There has been substantial investment by local governments, international health agencies and non- governmental organizations (NGOs) to increase supply and uptake of condoms (Xxxxxx et al., 2016; Xxxxxxx et al., 2008; Pienaar et al., 2016; Xxxxx et al., 2015). Increasing access to condoms and education about STI and HIV prevention has resulted in important gains in condom use, especially among high-risk populations like commercial sex workers (CSW) and men who have sex with men (MSM) (Xxxxxxx et al., 2008; Xxxxxx & Xxxxx, 2016; Xxxxxxxx et al., 2016; Subramanian et al., 2013). However, condom usage among CSWs continues to face barriers including client preference for unprotected sex, inconsistent condom supply, and policies that criminalize sex work (Xxxxxxxx et al., 2016; Jung, 2013). Among MSM populations, condom use is mediated by perceptions of risk and condom self-efficacy (Xxxxxx & Xxxxx, 2016; Xxxxxxxxxx et al., 2016; Jung, 2013). National rates of condom use in the US vary by race, age, gender, and sex act: 24.7% of men and 21.8% of women report condom use at last vaginal intercourse while 26.5% of insertive male partners, 44.1% of receptive male partners and 10.8% of receptive female partners report condom use at last anal intercourse (Reece et al., 2010). One of the barriers to condom usage in low-income countries is negative perception or rumors about condoms (Xxxxxxx et al., 2004); a study in Tanzania found that negative beliefs about condoms were significant predictors of willingness to use condoms (Xxxxxxx et al., 2012). Perceptions by the public about condom safety and efficacy directly affect their use and thus can adversely affect sexual and reproductive health programs (Xxxxx et al., 2014; Xxxxxxx et al., 2012). Negative beliefs about condoms include the belief that condoms cause cancer (Xxxxxxx et al., 2012). This is actually a concern among some condom manufacturers —specifically, the release of nitrosamines from condoms (ISO/TC 157, 2015). Nitrosamines are a class of carcinogenic compounds that can be produced in the manufacturing process of rubber products. Formed by the reaction of nitrites with secondary or tertiary amines, nitrosamines can vary in their carcinogenicity, with two potent carcinogens, N‐nitrosodiethylamine (NDEA) and N- nitrosodimethylamine (NDMA), often used as indicators of nitrosamine presence (Xxxxx, 2011). The World Health Organization (WHO), the European Union, and the US Environmental Protection Agency (EPA) classify NDEA and NDMA as probable or presumed human carcinogens (Xxxxx, 2011). The US Department of Health and Human Services released the 13th Report on Carcinogens in 2014, which included 15 listings of nitrosamines classified as “known or reasonably anticipated” carcinogens (NTP, 2014). Nitrosamines are linked with the development of multiple different types of cancer in many different animal models, including colon tumors in male rats, female mice and guinea pigs, as well as cervical tumors in female shrews following rectal or oral administration (NTP, 2014). Nitrosamines have been found in food, cosmetics, tobacco products, and rubber goods such as balloons, pacifiers, baby bottle teats, and also condoms (NTP, 2007; Dong et al., 2015; Altkofer et al., 2005; Fritschi et al., 2015; Xxxxxxxx & Xxxxxxxxxxxx, 2011). Nitrosamine-related cancer studies in humans are relatively scarce, though they include epidemiological studies of cancer mortality for occupational cohorts, as well as case-control or ecological studies conducted on dietary exposure (Monarca et al., 2001; de Vocht et al., 2007; NTP, 2014). Subsequent sections will discuss studies and regulations regarding nitrosamine exposure in occupational settings, food and drinking water, as well as rubber products like pacifiers, rubber gloves, and condoms1. The migration of nitrosamines from condoms to mucous membranes like the vagina and rectum, which have higher absorption, is a possible risk (Eisenbrand, 2005).

Conclusions. This study finds no evidence indicating an association between nitrosamine exposure from condoms Contrary to our expectations, findings suggest that interruptions by both males and incidence females lead to greater reporting of cervical domestic violence. Also, female interruptions seem to be more predictive of severe physical violence than male interruptions, while both male and colorectal cancerfemale interruptions are similarly predictive of sexual violence. Condoms provide substantial The mechanisms explaining these findings are unclear, thus highlighting the need for further research on the topic of interview environment and measurable public health benefits, its impact on response patterns and providers on global estimates of domestic violence prevalence.

There has been substantial investment by local governmentsI especially want to thank my committee members, international health agencies and non- governmental organizations (NGOs) to increase supply and uptake of condoms (Xxxxxx et al., 2016; Xxxxxxx et al., 2008; Pienaar et al., 2016; Xxxxx et al., 2015). Increasing access to condoms and education about STI and HIV prevention has resulted in important gains in condom use, especially among high-risk populations like commercial sex workers (CSW) and men who have sex with men (MSM) (Xxxxxxx et al., 2008; Xxxxxx & Xxxx Xxxxx, 2016; Xxxxxxxx et al., 2016; Subramanian et al., 2013). However, condom usage among CSWs continues to face barriers including client preference for unprotected sex, inconsistent condom supplyXxx Xxxxxx, and policies that criminalize sex work (Xxxxx Xxxxxxxx et al.for their support, 2016; Jung, 2013). Among MSM populations, condom use is mediated by perceptions of risk and condom self-efficacy (Xxxxxx & Xxxxx, 2016; Xxxxxxxxxx et al., 2016; Jung, 2013). National rates of condom use in the US vary by race, age, genderguidance, and sex act: 24.7% encouragement. Your influence in my achievement of men and 21.8% of women report condom use at last vaginal intercourse while 26.5% of insertive male partners, 44.1% of receptive male partners and 10.8% of receptive female partners report condom use at last anal intercourse (Reece et al., 2010). One of the barriers to condom usage in low-income countries is negative perception or rumors about condoms (Xxxxxxx et al., 2004); a study in Tanzania found that negative beliefs about condoms were significant predictors of willingness to use condoms (Xxxxxxx et al., 2012). Perceptions by the public about condom safety and efficacy directly affect their use and thus can adversely affect sexual and reproductive health programs (Xxxxx et al., 2014; Xxxxxxx et al., 2012). Negative beliefs about condoms include the belief that condoms cause cancer (Xxxxxxx et al., 2012). This is actually a concern among some condom manufacturers —specifically, the release of nitrosamines from condoms (ISO/TC 157, 2015). Nitrosamines this milestone are a class of carcinogenic compounds that can be produced in the manufacturing process of rubber products. Formed by the reaction of nitrites with secondary or tertiary amines, nitrosamines can vary in their carcinogenicity, with two potent carcinogens, N‐nitrosodiethylamine (NDEA) and N- nitrosodimethylamine (NDMA), often used as indicators of nitrosamine presence (Xxxxx, 2011)so much more than this paper. The World Health Organization (WHO), the European Union, most important acknowledgement of all goes to my wife and the US Environmental Protection Agency (EPA) classify NDEA sons who supported and NDMA as probable or presumed human carcinogens (Xxxxx, 2011)encouraged me to persevere. The US Department of Health and Human Services released the 13th Report on Carcinogens in 2014, which included 15 listings of nitrosamines classified as “known or reasonably anticipated” carcinogens (NTP, 2014)I think we did it. Nitrosamines are linked with the development of multiple different types of cancer in many different animal models, including colon tumors in male rats, female mice and guinea pigs, as well as cervical tumors in female shrews following rectal or oral administration (NTP, 2014). Nitrosamines have been found in food, cosmetics, tobacco products, and rubber goods such as balloons, pacifiers, baby bottle teats, and also condoms (NTP, 2007; Dong et al., 2015; Altkofer et al., 2005; Fritschi et al., 2015; Xxxxxxxx & Xxxxxxxxxxxx, 2011). Nitrosamine-related cancer studies in humans are relatively scarce, though they include epidemiological studies of cancer mortality for occupational cohorts, as well as case-control or ecological studies conducted on dietary exposure (Monarca et al., 2001; de Vocht et al., 2007; NTP, 2014). Subsequent sections I promise I will discuss studies and regulations regarding nitrosamine exposure in occupational settings, food and drinking water, as well as rubber products like pacifiers, rubber gloves, and condoms1. The migration of nitrosamines from condoms to mucous membranes like the vagina and rectum, which have higher absorption, is be a possible risk (Eisenbrand, 2005).lot more fun going forward… Chapter 1 Introduction 1

Conclusions. This study finds no evidence indicating an association The specificity of QFT-GIT was high and similar to TST at either cutoff. Test discordance observed in recruits with increased risk may be due to lower TST specificity, lower QFT-GIT sensitivity, or both. Negative QFT-GIT results for recruits born in countries with high–TB prevalence and whose TST is > 15mm suggest that QFT-GIT may be less sensitive than TST. Additional studies are needed to determine the risk of developing TB when TST and QFT-GIT results are discordant.

The causative agent of TB is the Mycobacterium tuberculosis bacillus. Mycobacterium tuberculosis infection (MTBI) occurs in food humans, who act as its primary reservoir. Approximately 2 billion people worldwide have quiescent or latent M. tuberculosis infection (LTBI) and water 5 Occupational exposure are at risk of developing TB (1).

There has been substantial investment by local governments, international health agencies and non- governmental organizations (NGOs) to increase supply and uptake of condoms (Xxxxxx et al., 2016; Xxxxxxx et al., 2008; Pienaar et al., 2016; Xxxxx et al., 2015). Increasing access to condoms and education about STI and HIV prevention has resulted in important gains in condom use, especially among high-risk populations like commercial sex workers (CSW) and men who have sex with men (MSM) (Xxxxxxx et al., 2008; Xxxxxx & Xxxxx, 2016; Xxxxxxxx et al., 2016; Subramanian et al., 20133). However, condom usage among CSWs continues elimination of TB remains elusive, even in high-resource countries because of continued transmission in groups at high risk of MTBI and progression to face barriers including client preference for unprotected sexTB, inconsistent condom supplydifficulties in detecting MTBI, and policies that criminalize sex work programmatic complacency (Xxxxxxxx et al., 2016; Jung, 20134). Among MSM populationsAround 4% of the US population is thought to have LTBI, condom use and is mediated by perceptions of risk a constant source for future TB and condom self-efficacy MTBI transmission (Xxxxxx & Xxxxx, 2016; Xxxxxxxxxx et al., 2016; Jung, 20135). National rates There is continued pressure to improve diagnostic and screening methods for detecting MTBI, including LTBI and infection manifesting as TB (6-8). Identifying and treating LTBI among those at high risk of condom use in the US vary by race, age, gender, developing TB is an important component for TB control and sex act: 24.7% of men and 21.8% of women report condom use at last vaginal intercourse while 26.5% of insertive male partners, 44.1% of receptive male partners and 10.8% of receptive female partners report condom use at last anal intercourse (Reece et al., 2010). One of the barriers to condom usage elimination in low-income countries is negative perception or rumors about condoms TB incidence regions, such as the US and Canada (Xxxxxxx et al.9, 2004); a study in Tanzania found that negative beliefs about condoms were significant predictors of willingness to use condoms (Xxxxxxx et al., 201210). Perceptions by No method exists for accurately detecting LTBI. Historically, the public about condom safety and efficacy directly affect their use and thus can adversely affect sexual and reproductive health programs only way to diagnose LTBI was the tuberculin skin test (Xxxxx et al.TST), 2014; Xxxxxxx et al., 2012which involved measuring immunologic delayed hypersensitivity to an intradermal injection of purified protein derivatives (PPD) made from M. tuberculosis (tuberculin PPD) (11). Negative beliefs about condoms include The TST has limitations in detecting LTBI in some settings. For example, where the belief prevalence of LTBI is low, the positive predictive value (PPV) of TST is hindered by cross reactions induced by sensitization to other mycobacteria (11). The development of interferon-gamma release assays (IGRA) offered an alternative to the TST and addressed some limitations in the TST (12, 13). MTBI typically induces an immune T-lymphocyte response which produces the cytokine interferon gamma (INF-γ) when the T-cells encounter mycobacterial antigens (13). Whole-blood IGRAs such as the 2nd generation, QuantiFERON®-TB Gold test (QFT-G) (Cellestis Limited, Xxxxxxxx, Xxxxxxxx, Australia) measure the amount of INF-γ released when blood is stimulated with specific Mycobacterium antigens (14). In 2007, the US Food and Drug Administration (FDA) approved the 3rd generation of IGRA for the detection of MTBI, the QuantiFERON®-TB Gold In-Tube test (QFT-GIT) (Cellestis Limited, Xxxxxxxx, Xxxxxxxx, Australia) (15). Like the TST, positive QFT-GIT results are highly associated with factors that condoms cause cancer historically contribute to MTBI (Xxxxxxx et al.15, 201216). However, QFT-GIT can exhibit discordance when compared to TST results and other IGRAs (15, 17-19). Absence of a “gold standard” to confirm MTBI limits IGRA assessments of accuracy and allows only estimates of sensitivity and specificity (15, 16). Approximations of sensitivity have been achieved by comparing the results of diagnostic tests to culture-confirmed cases of TB (15). Previous studies have assessed IGRAs among “assumed negative” populations at low-risk of MTBI, to better approximate specificity, with some consideration of test discordance (20- 22). Further research has been suggested to understand the factors associated with discordant test results (6, 15, 23). In light of the need for more research to understand IGRA accuracy and discordance, this study on QFT-GIT is part of a series of IGRA studies (21, 24- 26). This is actually study was conducted to add to the current discourse on the interpretation of LTBI screening results among low-risk populations when considering multiple testing methods. The analysis of cross-sectional data obtained from US Navy recruits in 2004 will quantify QFT-GIT specificity for a concern among some condom manufacturers —specificallypopulation at low-risk for MTBI. Additionally, this study will identify recruit characteristics and estimate their associations to discordant results between the release of nitrosamines from condoms QFT-GIT and TST. Results for QFT-GIT will also be compared to other IGRA results, performed at the same time (ISO/TC 157, 201521). Nitrosamines are a class of carcinogenic compounds that can be produced in the manufacturing process of rubber products. Formed by the reaction of nitrites with secondary or tertiary amines, nitrosamines can vary in their carcinogenicity, with two potent carcinogens, N‐nitrosodiethylamine (NDEA) and N- nitrosodimethylamine (NDMA), often used as indicators of nitrosamine presence (Xxxxx, 2011). The World Health Organization (WHO), the European Union, and the US Environmental Protection Agency (EPA) classify NDEA and NDMA as probable or presumed human carcinogens (Xxxxx, 2011). The US Department of Health and Human Services released the 13th Report on Carcinogens in 2014, which included 15 listings of nitrosamines classified as “known or reasonably anticipated” carcinogens (NTP, 2014). Nitrosamines are linked with the development of multiple different types of cancer in many different animal models, including colon tumors in male rats, female mice and guinea pigs, as well as cervical tumors in female shrews following rectal or oral administration (NTP, 2014).

TB usually affects the lungs and is transmitted from human-printed sources cited 53 Introduction Condoms are one of the most important public health tools in sexual healthto-human through inhalation. The bacterium that is primarily responsible for causing TB, playing roles in human immunodeficiency virus Mycobacterium tuberculosis (HIV) prevention, prevention of sexually transmitted infections (STIsMTB), was first identified and family planningdescribed in 1882 by Xxxxxx Xxxx. There has been substantial investment Infections with MTB (MTBI) can be classified as either an active disease (referred to as TB) with clinical symptoms and pathological signs, or as an asymptomatic non-contagious state, often called “latent” TB infection (LTBI). People with TB may present with constitutional symptoms, such as weight loss, fever, chills, night sweats, and weakness, but may also present with symptoms associated with disease in specific organs. The lung is most often affected as evidence by local governmentssymptoms of cough, international health agencies sputum production, hemoptysis, and non- governmental organizations chest pain, that are typically accompanied by an abnormal chest x-ray. Pulmonary TB accounts for approximately 80% of newly diagnosed TB in the U. S. while 20% to 30% involves extra-pulmonary sites. Traditional methods used to diagnose TB rely primarily on sputum smear microscopy, bacteriological culture, and clinical examination, although newer and rapid molecular tests are being used with increasing frequency. A combination of sputum culture and clinical exam are considered the gold standard for definitive TB diagnosis. TB is curable with a standard six month course of four antimicrobial agents (NGOs) to increase supply isoniazid, rifampicin, pyrazinamide, and uptake ethambutol), but, if left untreated, 70% of condoms cases worldwide will not survive 10 years (Xxxxxx et al.World Health Organization, 2016; Xxxxxxx et al., 2008; Pienaar et al., 2016; Xxxxx et al., 2015). Increasing access to condoms and education about STI and HIV prevention has resulted in important gains in condom use, especially among high-risk populations like commercial sex workers (CSW) and men who have sex with men (MSM) (Xxxxxxx et al., 2008; Xxxxxx & Xxxxx, 2016; Xxxxxxxx et al., 2016; Subramanian et al., 2013). However, condom usage among CSWs continues to face barriers including client preference for unprotected sex, inconsistent condom supply, and policies that criminalize sex work (Xxxxxxxx et al., 2016; Jung, 2013). Among MSM populations, condom use is mediated by perceptions of risk and condom self-efficacy (Xxxxxx & Xxxxx, 2016; Xxxxxxxxxx et al., 2016; Jung, 2013). National rates of condom use in the US vary by race, age, gender, and sex act: 24.7% of men and 21.8% of women report condom use at last vaginal intercourse while 26.5% of insertive male partners, 44.1% of receptive male partners and 10.8% of receptive female partners report condom use at last anal intercourse (Reece et al., 2010). One of the barriers to condom usage in low-income countries is negative perception or rumors about condoms (Xxxxxxx et al., 2004); a study in Tanzania found that negative beliefs about condoms were significant predictors of willingness to use condoms (Xxxxxxx et al., 2012). Perceptions by the public about condom safety and efficacy directly affect their use and thus can adversely affect sexual and reproductive health programs (Xxxxx et al., 2014; Xxxxxxx et al., 2012). Negative beliefs about condoms include the belief that condoms cause cancer (Xxxxxxx et al., 2012). This is actually a concern among some condom manufacturers —specifically, the release of nitrosamines from condoms (ISO/TC 157, 2015). Nitrosamines are a class of carcinogenic compounds that can be produced in the manufacturing process of rubber products. Formed by the reaction of nitrites with secondary or tertiary amines, nitrosamines can vary in their carcinogenicity, with two potent carcinogens, N‐nitrosodiethylamine (NDEA) and N- nitrosodimethylamine (NDMA), often used as indicators of nitrosamine presence (Xxxxx, 2011). The World Health Organization (WHO), the European Union, and the US Environmental Protection Agency (EPA) classify NDEA and NDMA as probable or presumed human carcinogens (Xxxxx, 2011). The US Department of Health and Human Services released the 13th Report on Carcinogens in 2014, which included 15 listings of nitrosamines classified as “known or reasonably anticipated” carcinogens (NTP, 2014). Nitrosamines are linked with the development of multiple different types of cancer in many different animal models, including colon tumors in male rats, female mice and guinea pigs, as well as cervical tumors in female shrews following rectal or oral administration (NTP, 2014). Nitrosamines have been found in food, cosmetics, tobacco products, and rubber goods such as balloons, pacifiers, baby bottle teats, and also condoms (NTP, 2007; Dong et al., 2015; Altkofer et al., 2005; Fritschi et al., 2015; Xxxxxxxx & Xxxxxxxxxxxx, 2011). Nitrosamine-related cancer studies in humans are relatively scarce, though they include epidemiological studies of cancer mortality for occupational cohorts, as well as case-control or ecological studies conducted on dietary exposure (Monarca et al., 2001; de Vocht et al., 2007; NTP, 2014). Subsequent sections will discuss studies and regulations regarding nitrosamine exposure in occupational settings, food and drinking water, as well as rubber products like pacifiers, rubber gloves, and condoms1. The migration of nitrosamines from condoms to mucous membranes like the vagina and rectum, which have higher absorption, is a possible risk (Eisenbrand, 2005).

TABLE OF CONTENTS INTRODUCTION 1 BACKGROUND 3 METHODS 8 RESULTS 19 DISCUSSION 24 CONCLUSIONS 33 REFERENCES 34 INTRODUCTION‌ End-stage renal disease (ESRD) has increased by 1000% in the past 3 decades, proving to be a significant health concern in the United Sates. In 1980, there were 60,000 persons with ESRD though in 2018 there were over 700,000 Americans living with ESRD (1). The expense of Chronic Kidney Disease (CKD) and ESRD has a significant impact on the United States economy and in 2018, CKD and ESRD accounted for mapping approximately 7% of Medicare expenditure, equating to $114 billion per year (2,3). It is well established that kidney transplantation is the optimal therapy for ESRD as it provides increased survival, better quality of life, and GISis less costly when compared with conventional dialysis (4–7). Since the advent of effective antiretroviral therapy, persons living with HIV (PLWH) are surviving longer and accumulating comorbidities. While HIV specific mortality has decreased, unfortunately, there continues to be a growing HIV epidemic, particularly in the southeastern United States. In 2017, the south accounted for 52% of the 38,739 new HIV diagnoses (8). As the HIV population ages, ESRD has emerged as a significant cause of morbidity and mortality, with PLWH being three times more likely to develop ESRD compared with the general population and is thought to compromise approximately 1.5% of the dialysis population (9,10). Additionally, compared with HIV- negative counterparts, PLWH experience a lower one- and five- year survival on dialysis (11). Despite this, there is growing evidence that PLWH are less likely to be placed on the organ waitlist and 47% less likely to receive a living donor kidney transplant (12). In order to improve survival and increase transplant rates among PLWH, it is critical to better understand the barriers to achieving a kidney transplant in this high-risk population. The objective of this thesis project was to identify and describe the HIV positive dialysis population in ESRD Network 6, the region with the lowest rates of kidney transplantation in the nation. Additionally, to compare their progression through the early steps (referral, evaluation, and waitlisting) of kidney transplantation to general dialysis population, and highlight patient and dialysis level characteristics that may influence access to kidney transplantation. This was accomplished through creating a novel HIV-ESRD dataset that identifies PLWH as well as her encyclopedic knowledge in finding those who proceeded through the early steps of transplantation.

The widespread use of affective antiretroviral therapy (ART) has decreased the prevalence of HIV-associated nephropathies (13,14), playing roles in human immunodeficiency however, PLWH are still developing CKD and ESRD faster than HIV negative counterparts. This is largely due to co-morbidities (diabetes mellitus, cardiovascular disease, hypertension, and metabolic syndrome), co- infection with hepatitis C virus (HIV) prevention, prevention of sexually transmitted infections (STIsHCV), medication induced injury, and family planning. There has been substantial investment by local governments, international health agencies and non- governmental organizations accelerated aging seeing in chronic HIV infection (NGOs) to increase supply and uptake of condoms (Xxxxxx et al., 2016; Xxxxxxx et al., 2008; Pienaar et al., 2016; Xxxxx et al., 20159,15,16). Increasing PLWH of black race are especially at risk for progression from CKD to ESRD. A study performed in Baltimore, Maryland revealed that African-Americans were at an increased risk for incident CKD and developed ESRD markedly faster than white subjects (HR, 17.7 [95% CI 2.5-127.0]) (17). ESRD among PLWH is particularly present in the southeast. In 2000, ESRD Network 6 had the 4th highest percentage of PLWH on dialysis at a proportion of 1.9% compared to an national average of 1.5%(10). Unfortunately, the southeastern region of the US continues to have the highest burden of CKD and ESRD with Georgia, North Carolina and South Carolina being states with some of the highest age-standardized CKD disability-adjusted life years (18,19). This coupled by the ongoing HIV epidemic in the southeast makes ESRD Network 6 a unique region to study the coexistence of ESRD and access to condoms kidney transplantation among PLWH. With significant risk of progression from CKD to ESRD, it is imperative to understand access to transplantation among this vulnerable patient population. Renal transplantation is a feasible treatment option for PLWH with ESRD. In the 1980’s, HIV infection was considered a contraindication for transplantation and education about STI and US legal code was amended to make it a federal crime to transplant tissue from HIV prevention has resulted in important gains in condom use, especially among high-risk populations like commercial sex workers positive donors (CSW) and men who have sex with men (MSM) (Xxxxxxx et al., 2008; Xxxxxx & Xxxxx, 2016; Xxxxxxxx et al., 2016; Subramanian et al., 201320). HoweverIt was theorized that the effect of immunosuppression would contribute to progression of HIV disease, condom usage among CSWs continues lead to face barriers including client preference for unprotected sexmore episodes of infection and increased rate of death; making it an inappropriate allocation of an organ. Between 1987 to 1997, inconsistent condom supply, and policies that criminalize sex work (Xxxxxxxx et al., 2016; Jung, 2013). Among MSM populations, condom use is mediated by perceptions of risk and condom self-efficacy (Xxxxxx & Xxxxx, 2016; Xxxxxxxxxx et al., 2016; Jung, 2013). National rates of condom use there were 32 kidney transplants performed in the US vary in PLWH (mostly unintentional transplantation), with reported 3-year graft survival of 53% and patient survival 83% (21,22). These transplants though were prior to significant improvement in medications used to treat PLWH. In 2003, Stock et al published promising outcomes on 14 HIV-positive patients who underwent transplantation. At a mean follow up of 480 days, 10 out of 10 (100%) of patients who received kidney transplants were alive with functioning grafts. There was no evidence of HIV disease progression and HIV did not seem to have an impact on graft survival (23). Around the same time, driven out of lack of access to dialysis, colleagues in South Africa performed the first kidney transplants from HIV-positive organ donors to HIV-positive recipients, showing that transplantation among PLWH was safe and feasible (24). With revived interest in transplanting PLWH, there have been a number of single center studies and a large multicenter study of 150 HIV-positive renal transplant recipients which all reported transplant outcomes for PLWH that were similar to the general transplant population 19(25–28). With better HIV care and improved understanding of medication interactions, PLWH in the United States are not only eligible for HIV-negative organs, but HIV-positive organs as well. In 2013, the HIV Organ Procurement Equity (HOPE) Act was signed into law, reversing the 1988 amendment, allowing HIV positive organs to be transplanted into HIV positive recipients. This policy change is estimated to increase the donor pool by race300-500 organs, ageproviding a unique opportunity to increase utilization of these organs and increase rates of kidney transplantation in HIV positive individuals 20(29). The transplant evaluation process is a multifaceted and complex process with the southeastern region performing the least transplants. Though it is possible for patients to be referred for kidney transplant prior to starting dialysis, genderthe majority of ESRD patients start on dialysis before they are referred to a transplant center. Within 60 days of starting dialysis, patients are required by law to be educated on the risks and benefits of transplantation and if eligible, are referred by a dialysis provider to a transplant center. The transplant center then decides on their waitlist candidacy through conducting thorough medical evaluations (often inclusive of multiple studies and specialty evaluations), performing a psychosocial evaluation, assessing their social support network and financial ability to fund kidney transplantation. When this step is completed, the patient can be waitlisted with the eventual hope of receiving a living or deceased donor kidney transplant. To better understand how well dialysis facilities were performing in referring patients to kidney transplant, Xx. Xxxxxx Xxxxxx (co-I; Department of Surgery & Department of Epidemiology) and team reported in 2014 that ESRD Network 6 has the lowest rates of kidney transplantation in the nation, and sex actthat Georgia had the lowest of all 50 states (18,30,31) (Figure 1). Factors associated with decreased access to transplant include demographic differences in the southeast, racial disparities, socioeconomic influences, distance to transplant center, provider knowledge and awareness of transplantation (18,32,33). Because no national surveillance data exist on steps prior to waitlisting, the Southeastern Kidney Transplant Coalition developed a novel data registry for referral and evaluation for transplantation among all 9 transplant centers in Xxxxxxx, Xxxxx Xxxxxxxx xxx Xxxxx Xxxxxxxx (X00XX000000, PI: 24.7Xxxxxx). They found substantial variability in transplant access at the dialysis facility level where some facilities referred 0% of men patients and 21.8others referred 76% of women report condom use at last vaginal intercourse while 26.5% of insertive male partners, 44.1% of receptive male partners and 10.8% of receptive female partners report condom use at last anal intercourse (Reece et al., 201034). One Dialysis facility variability in transplant rates for HIV patients have not been described because currently no data exists linking HIV and ESRD care within a state or region. Factors influencing referral to kidney transplantation in PLWH have yet to be described in ESRD Network 6 and will direct construction of future interventions. Identifying PLWH who are on dialysis is difficult to do. Since 2005, there are scarce data on the barriers to condom usage incidence and prevalence of PLWH requiring dialysis. As part of a condition of participation in lowthe ESRD Medicare program, Centers for Medicare and Medicaid Services (CMS) medical evidence form (CMS 2728 form) is completed on every ESRD patient upon initiation of dialysis. CMS funds dialysis for ESRD patient and the surgical procedure and immunosuppressants for those who undergo kidney transplantation. The medical evidence form provides evidence of an ESRD condition, registers patients into a national renal registry, documents medical co-income countries is negative perception or rumors about condoms morbidities and other clinical data in dialysis patients, and ensures quality care for ERSD patients (Xxxxxxx et al., 2004); a study in Tanzania found that negative beliefs about condoms were significant predictors of willingness to use condoms (Xxxxxxx et al., 201235). Perceptions by In 2005, HIV serostatus was removed as an ESRD-related condition on the public about condom safety and efficacy directly affect their use and thus can adversely affect sexual and reproductive health programs medical evidence form due to concerns regarding disclosure of HIV status (Xxxxx et al., 2014; Xxxxxxx et al., 201236). Negative beliefs about condoms include the belief that condoms cause cancer Presently, in order to identity PLWH on dialysis, HIV status is inferred through pharmacy prescription data (Xxxxxxx et al., 201212). This ascertainment method is actually a concern among some condom manufacturers —specificallysuboptimal, as it may misclassify patients on pre-exposure prophylaxis as being on ART, may fail to identify PLWH not engaged in HIV care, and lacks patient-level epidemiologic and clinical data. Nonetheless, pharmacy prescription data is the release of nitrosamines from condoms (ISO/TC 157, 2015). Nitrosamines are a class of carcinogenic compounds only currently available method that can be produced used. In this study, Medicare prescription part D claims data was used to identify PLWH on dialysis. In 2016, there was 81% participation of Medicare part D among hemodialysis patients, suggestive that majority of the HIV population is captured in this study (37). METHODS‌ Hypothesis: Persons living with HIV in ESRD Network 6 are less likely to traverse through the multistep process of kidney transplantation compared to HIV-negative counterparts in the manufacturing process setting of rubber productsESRD. Formed by Specific Aims Aim 1: To identify and describe the reaction characteristics of nitrites with secondary or tertiary aminesPLWH and ESRD in ESRD Network 6. Aim 2: To describe the distribution and timing of early steps of kidney transplant inclusive of referral, nitrosamines can vary in their carcinogenicity, with two potent carcinogens, N‐nitrosodiethylamine (NDEA) and N- nitrosodimethylamine (NDMA), often used as indicators of nitrosamine presence (Xxxxx, 2011). The World Health Organization (WHO), the European Unionevaluation, and the US Environmental Protection Agency (EPA) classify NDEA waitlisting among PLWH compared with HIV negative individuals with ESRD in Network 6. Aim 3: To identify patient-level and NDMA as probable or presumed human carcinogens (Xxxxx, 2011). The US Department of Health dialysis facility-level factors that are associated with time to referral and Human Services released the 13th Report on Carcinogens in 2014, which included 15 listings of nitrosamines classified as “known or reasonably anticipated” carcinogens (NTP, 2014). Nitrosamines are linked with the development of multiple different types of cancer in many different animal models, including colon tumors in male rats, female mice and guinea pigs, as well as cervical tumors in female shrews following rectal or oral administration (NTP, 2014). Nitrosamines have been found in food, cosmetics, tobacco products, and rubber goods such as balloons, pacifiers, baby bottle teats, and also condoms (NTP, 2007; Dong et altime to waitlisting., 2015; Altkofer et al., 2005; Fritschi et al., 2015; Xxxxxxxx & Xxxxxxxxxxxx, 2011). Nitrosamine-related cancer studies in humans are relatively scarce, though they include epidemiological studies of cancer mortality for occupational cohorts, as well as case-control or ecological studies conducted on dietary exposure (Monarca et al., 2001; de Vocht et al., 2007; NTP, 2014). Subsequent sections will discuss studies and regulations regarding nitrosamine exposure in occupational settings, food and drinking water, as well as rubber products like pacifiers, rubber gloves, and condoms1. The migration of nitrosamines from condoms to mucous membranes like the vagina and rectum, which have higher absorption, is a possible risk (Eisenbrand, 2005).

ABSTRACT BACKGROUND: Breastfeeding is vital for providing young infants with the nutrients they need for healthy growth and development; however, there are several socio-economic and health determinants that predict whether or not mothers are able to initiate and maintain it for the recommended duration. With changing demographics among first time mothers, we examined the current association between maternal education and self-reported breastfeeding duration in the U.S. METHODS: Utilizing national and population-based cross-sectional data from the 2011-2013 National Survey of Family Growth (NSFG), we examined the association between maternal education and self-reported breastfeeding duration among primiparas aged 15-44 years. Breastfeeding duration was examined as an ordinal variable. We estimated adjusted odds ratios and 95% confidence intervals using a multivariable ordinal logistic regression, while controlling for several potential confounders. RESULTS: Of the 2069 participants who were eligible for our analysis, 66.2% of first time mothers breastfed. 27.1% of them breastfed for less than a week to 8 weeks, 46.01% breastfed for 9 to 52 weeks and 15.12% breastfed for more than one-year-old and were still breastfeeding at the Emory Center time of interview.

There has been substantial investment by local governments, international health agencies and non- governmental organizations (NGOs) to increase supply and uptake of condoms (Xxxxxx et al., 2016; Xxxxxxx et al., 2008; Pienaar et al., 2016; Xxxxx et al., 2015). Increasing access to condoms and education about STI and HIV prevention has resulted in important gains in condom use, especially among high-risk populations like commercial sex workers (CSW) and men who have sex with men (MSM) (Xxxxxxx et al., 2008; Xxxxxx & Xxxxx, 2016; Xxxxxxxx et al., 2016; Subramanian et al., 2013). However, condom usage among CSWs continues to face barriers including client preference after controlling for unprotected sex, inconsistent condom supply, and policies that criminalize sex work (Xxxxxxxx et al., 2016; Jung, 2013). Among MSM populations, condom use is mediated by perceptions of risk and condom self-efficacy (Xxxxxx & Xxxxx, 2016; Xxxxxxxxxx et al., 2016; Jung, 2013). National rates of condom use in the US vary by race, age, genderrace and ethnicity, marital status, religious beliefs, employment status and sex act: 24.7% of men federal poverty level. Women with a college education and 21.8% of above were less likely to not breastfeed and to have shorter breastfeeding duration times. (aOR=0.59 CI= 0.47, 0.74) compared to women report condom use at last vaginal intercourse while 26.5% of insertive male partnerswith lower education. In addition, 44.1% of receptive male partners women with less than high school education, even though it was not statistically significant, also were less likely to not breastfeed and 10.8% of receptive female partners report condom use at last anal intercourse to have shorter breastfeeding duration times (Reece et al.aOR=0.75 CI= 0.40, 2010). One of the barriers to condom usage in low-income countries is negative perception or rumors about condoms (Xxxxxxx et al., 2004); a study in Tanzania found that negative beliefs about condoms were significant predictors of willingness to use condoms (Xxxxxxx et al., 2012). Perceptions by the public about condom safety and efficacy directly affect their use and thus can adversely affect sexual and reproductive health programs (Xxxxx et al., 2014; Xxxxxxx et al., 2012).

Subsequent sections will discuss studies and regulations regarding nitrosamine exposure in occupational settings, food and drinking water, as well as rubber products like pacifiers, rubber gloves, and condoms1. The migration of nitrosamines from condoms to mucous membranes like the vagina and rectum, which have higher absorption, is a possible risk (Eisenbrand, 20051.35).

Conclusions. This study finds no evidence indicating an association between nitrosamine exposure from condoms and incidence of cervical and colorectal cancer. Condoms provide substantial and measurable public health benefitsThese results add to the inconsistent findings regarding IPV, relationship power, and providers SRH outcomes. Future research may wish to examine differences in these variables among younger and healthcare organizations should continue older adolescents and consider the role of a sexual network, and other partner characteristics. High STI rates among those experiencing IPV highlights the need to recommend promote prevention methods that women can control, including testing, PrEP, and promote them without hesitationHPV vaccinations. Lack Additionally, the high rates of ecological association between state-level cervical STIs and colorectal cancer incidence and nitrosamine exposure from low reported condom use overall calls for a crossincreased sex education in high schools that stresses STI risk and the importance of health protective behaviors to reduce the spread of STIs among high-sectional study risk adolescents including African American emerging adults.

There has been substantial investment by local governments, international health agencies and non- governmental organizations (NGOs) to increase supply and uptake of condoms (Xxxxxx et al., 2016; Xxxxxxx et al., 2008; Pienaar et al., 2016; Xxxxx et al., 2015). Increasing access to condoms and education about FIGURE 6 MEDIATION PATHWAY FOR STI and HIV prevention has resulted in important gains in condom use, especially among high-risk populations like commercial sex workers (CSW) and men who have sex with men (MSM) (Xxxxxxx et al., 2008; Xxxxxx & Xxxxx, 2016; Xxxxxxxx et al., 2016; Subramanian et al., 2013). However, condom usage among CSWs continues to face barriers including client preference for unprotected sex, inconsistent condom supply, and policies that criminalize sex work (Xxxxxxxx et al., 2016; Jung, 2013). Among MSM populations, condom use is mediated by perceptions of risk and condom self-efficacy (Xxxxxx & Xxxxx, 2016; Xxxxxxxxxx et al., 2016; Jung, 2013). National rates of condom use in the US vary by race, age, gender, and sex act: 24.7% of men and 21.8% of women report condom use at last vaginal intercourse while 26.5% of insertive male partners, 44.1% of receptive male partners and 10.8% of receptive female partners report condom use at last anal intercourse (Reece et al., 2010). One of the barriers to condom usage in low-income countries is negative perception or rumors about condoms (Xxxxxxx et al., 2004); a study in Tanzania found that negative beliefs about condoms were significant predictors of willingness to use condoms (Xxxxxxx et al., 2012). Perceptions by the public about condom safety and efficacy directly affect their use and thus can adversely affect sexual and reproductive health programs (Xxxxx et al., 2014; Xxxxxxx et al., 2012). Negative beliefs about condoms include the belief that condoms cause cancer (Xxxxxxx et al., 2012). This is actually a concern among some condom manufacturers —specifically, the release of nitrosamines from condoms (ISO/TC 157, 2015). Nitrosamines are a class of carcinogenic compounds that can be produced in the manufacturing process of rubber products. Formed by the reaction of nitrites with secondary or tertiary amines, nitrosamines can vary in their carcinogenicity, with two potent carcinogens, N‐nitrosodiethylamine (NDEA) and N- nitrosodimethylamine (NDMA), often used as indicators of nitrosamine presence (Xxxxx, 2011). The World Health Organization (WHO), the European Union, and the US Environmental Protection Agency (EPA) classify NDEA and NDMA as probable or presumed human carcinogens (Xxxxx, 2011). The US Department of Health and Human Services released the 13th Report on Carcinogens in 2014, which included 15 listings of nitrosamines classified as “known or reasonably anticipated” carcinogens (NTP, 2014). Nitrosamines are linked with the development of multiple different types of cancer in many different animal models, including colon tumors in male rats, female mice and guinea pigs, as well as cervical tumors in female shrews following rectal or oral administration (NTP, 2014). Nitrosamines have been found in food, cosmetics, tobacco products, and rubber goods such as balloons, pacifiers, baby bottle teats, and also condoms (NTP, 2007; Dong et al., 2015; Altkofer et al., 2005; Fritschi et al., 2015; Xxxxxxxx & Xxxxxxxxxxxx, 2011).

Conclusions. This The findings from this study finds no evidence indicating an association between nitrosamine exposure from condoms provide insight into variabilities of toxicological endpoints in ATSDR and incidence of cervical and colorectal cancer. Condoms provide substantial and measurable other governmental databases, which could be useful in public health benefits, guidance and providers risk assessments.

There has been substantial investment by local governmentsI especially want to thank my committee members, international health agencies and non- governmental organizations (NGOs) to increase supply and uptake of condoms (Xxxxxx et al., 2016; Xxxxxxx et al., 2008; Pienaar et al., 2016; Xxxxx et al., 2015). Increasing access to condoms and education about STI and HIV prevention has resulted in important gains in condom use, especially among high-risk populations like commercial sex workers (CSW) and men who have sex with men (MSM) (Xxxxxxx et al., 2008; Xxxxxx & Xxxx Xxxxx, 2016; Xxxxxxxx et al., 2016; Subramanian et al., 2013). However, condom usage among CSWs continues to face barriers including client preference for unprotected sex, inconsistent condom supplyXxx Xxxxxx, and policies that criminalize sex work (Xxxxx Xxxxxxxx et al.for their support, 2016; Jung, 2013). Among MSM populations, condom use is mediated by perceptions of risk and condom self-efficacy (Xxxxxx & Xxxxx, 2016; Xxxxxxxxxx et al., 2016; Jung, 2013). National rates of condom use in the US vary by race, age, genderguidance, and sex act: 24.7% encouragement. Your influence in my achievement of men and 21.8% of women report condom use at last vaginal intercourse while 26.5% of insertive male partners, 44.1% of receptive male partners and 10.8% of receptive female partners report condom use at last anal intercourse (Reece et al., 2010). One of the barriers to condom usage in low-income countries is negative perception or rumors about condoms (Xxxxxxx et al., 2004); a study in Tanzania found that negative beliefs about condoms were significant predictors of willingness to use condoms (Xxxxxxx et al., 2012). Perceptions by the public about condom safety and efficacy directly affect their use and thus can adversely affect sexual and reproductive health programs (Xxxxx et al., 2014; Xxxxxxx et al., 2012). Negative beliefs about condoms include the belief that condoms cause cancer (Xxxxxxx et al., 2012). This is actually a concern among some condom manufacturers —specifically, the release of nitrosamines from condoms (ISO/TC 157, 2015). Nitrosamines this milestone are a class of carcinogenic compounds that can be produced in the manufacturing process of rubber products. Formed by the reaction of nitrites with secondary or tertiary amines, nitrosamines can vary in their carcinogenicity, with two potent carcinogens, N‐nitrosodiethylamine (NDEA) and N- nitrosodimethylamine (NDMA), often used as indicators of nitrosamine presence (Xxxxx, 2011)so much more than this paper. The World Health Organization (WHO), the European Union, most important acknowledgement of all goes to my wife and the US Environmental Protection Agency (EPA) classify NDEA sons who supported and NDMA as probable or presumed human carcinogens (Xxxxx, 2011)encouraged me to persevere. The US Department of Health and Human Services released the 13th Report on Carcinogens in 2014, which included 15 listings of nitrosamines classified as “known or reasonably anticipated” carcinogens (NTP, 2014)I think we did it. Nitrosamines are linked with the development of multiple different types of cancer in many different animal models, including colon tumors in male rats, female mice and guinea pigs, as well as cervical tumors in female shrews following rectal or oral administration (NTP, 2014). Nitrosamines have been found in food, cosmetics, tobacco products, and rubber goods such as balloons, pacifiers, baby bottle teats, and also condoms (NTP, 2007; Dong et al., 2015; Altkofer et al., 2005; Fritschi et al., 2015; Xxxxxxxx & Xxxxxxxxxxxx, 2011). Nitrosamine-related cancer studies in humans are relatively scarce, though they include epidemiological studies of cancer mortality for occupational cohorts, as well as case-control or ecological studies conducted on dietary exposure (Monarca et al., 2001; de Vocht et al., 2007; NTP, 2014). Subsequent sections I promise I will discuss studies and regulations regarding nitrosamine exposure in occupational settings, food and drinking water, as well as rubber products like pacifiers, rubber gloves, and condoms1. The migration of nitrosamines from condoms to mucous membranes like the vagina and rectum, which have higher absorption, is be a possible risk (Eisenbrand, 2005).lot more fun going forward… Chapter 1 Introduction 1

Conclusions. The associations between food insecurity and diabetes as well as the high prevalence of both conditions give evidence that food insecurity should be addressed in clinical settings. This study finds no evidence indicating an association between nitrosamine exposure from condoms and incidence makes the case that electronic medical records should include measures of cervical and colorectal cancerfood insecurity for appropriate referral. Condoms provide substantial and measurable public health benefitsMore research, and providers and healthcare organizations should especially longitudinal, is necessary to continue to recommend examining this association.

There has been substantial investment by local governments, international health agencies and non- governmental organizations (NGOs) to increase supply and uptake of condoms (Xxxxxx et al., 2016; Xxxxxxx et al., 2008; Pienaar et al., 2016; Xxxxx et al., 2015).

Historically communicable diseases or infectious diseases were the main concerns, contributing to the mortality and morbidity. After the end of 19th century, developing the knowledge and treatments for infectious diseases has contributed to the steep declines in human immunodeficiency virus mortality from infectious diseases (HIV) prevention1). As a result people live longer but people became suffering from different diseases, prevention of sexually transmitted infections (STIs)such as cancers, heart diseases, diabetes, and family planning. There has been substantial investment by local governments, international health agencies and non- governmental organizations dementia (NGOs) to increase supply and uptake of condoms (Xxxxxx et al., 2016; Xxxxxxx et al., 2008; Pienaar et al., 2016; Xxxxx et al., 20152). Increasing access Low bone mineral density and NAFLD are not directly related to condoms a life-threatening conditions, and education about STI and HIV prevention has resulted in important gains in condom use, especially among high-risk populations like commercial sex workers (CSW) and men who they have sex with men (MSM) (Xxxxxxx et al., 2008; Xxxxxx & Xxxxx, 2016; Xxxxxxxx et al., 2016; Subramanian et al., 2013)not attracted so much attention. However, condom usage among CSWs continues to face barriers including client preference for unprotected sexlow bone mineral density can increase the rate of bone fracture, inconsistent condom supplywhich decrease the patients’ quality of life. The number of people with NAFLD is increasing as obesity is becoming more prevalent. Therefore, these two factors can have a great impact on public health, and policies that criminalize sex work considering the association can give us a better strategy for prevention and therapy, and must be beneficial for the future researches. Bone Mineral Density Bone mineral density (Xxxxxxxx et al., 2016; Jung, 2013BMD) is widely used to diagnose osteoporosis (3). Among MSM populationsOsteoporosis is a disease “characterized by low bone mass, condom use is mediated deterioration of bone tissue and disruption of bone architecture, compromised bone strength and an increase in the risk of fracture.” (3) Xxxxxx reported 10.2 million Americans aged 50 years and older are affected by perceptions of risk and condom self-efficacy osteoporosis in 2013 (Xxxxxx & Xxxxx, 2016; Xxxxxxxxxx et al., 2016; Jung, 20134). National rates Maintaining BMD level is beneficial to protect against incidents of condom use bone fractures. Prospective cohort studies have demonstrated that people with low bone mineral density of femur (5, 6), lumber spine (5, 7), radius (6, 8) or forearm (9) have higher risk of bone fracture. Meta-analysis reported -1 S.D. BMD people have 1.5 to 2.6 times as high risk of bone fracture (10). In the industrialized countries, the number of people with osteoporosis or low bone mineral density is increasing, as population is aging. “It is anticipated that the number of fractures will grow proportionally.” (3) “Annually, two million fractures are attributed to osteoporosis, causing more than 432,000 hospital admissions, almost 2.5 million medical office visits and about 180,000 nursing home admissions in the US vary by raceU.S.” (3) Therefore, age, gender, keeping bone mineral density is also beneficial from the view of public health and sex act: 24.7% of men and 21.8% of women report condom use at last vaginal intercourse while 26.5% of insertive male partners, 44.1% of receptive male partners and 10.8% of receptive female partners report condom use at last anal intercourse (Reece et alhealthcare economy., 2010).

There has been substantial investment by local governments, international health agencies and non- governmental organizations (NGOs) to increase supply and uptake of condoms (Xxxxxx et al., 2016; Xxxxxxx et al., 2008; Pienaar et al., 2016; Xxxxx et al., 2015)You make this work worthwhile. Increasing access to condoms and education about STI and HIV prevention has resulted in important gains in condom use, especially among high-risk populations like commercial sex workers (CSW) and men who have sex with men (MSM) (Xxxxxxx et al., 2008; Xxxxxx & Xxxxx, 2016; Xxxxxxxx et al., 2016; Subramanian et al., 2013). However, condom usage among CSWs continues to face barriers including client preference I am grateful for unprotected sex, inconsistent condom supply, and policies that criminalize sex work (Xxxxxxxx et al., 2016; Jung, 2013). Among MSM populations, condom use is mediated by perceptions of risk and condom self-efficacy (Xxxxxx & Xxxxx, 2016; Xxxxxxxxxx et al., 2016; Jung, 2013). National rates of condom use in the US vary by race, age, gender, and sex act: 24.7% of men and 21.8% of women report condom use at last vaginal intercourse while 26.5% of insertive male partners, 44.1% of receptive male partners and 10.8% of receptive female partners report condom use at last anal intercourse (Reece et al., 2010). One of the barriers to condom usage in low-income countries is negative perception or rumors about condoms (Xxxxxxx et al., 2004); a study in Tanzania found that negative beliefs about condoms were significant predictors of your willingness to use condoms (Xxxxxxx et al., 2012)participate in my study. Perceptions by Many students on campuses across the public about condom safety and efficacy directly affect their use and thus can adversely affect sexual and reproductive health programs (Xxxxx et al., 2014; Xxxxxxx et al., 2012). Negative beliefs about condoms include country act to create change on the belief issues that condoms cause cancer (Xxxxxxx et al., 2012). This is actually a concern among some condom manufacturers —specifically, the release of nitrosamines from condoms (ISO/TC 157, 2015). Nitrosamines are a class of carcinogenic compounds that can be produced in the manufacturing process of rubber products. Formed by the reaction of nitrites with secondary or tertiary amines, nitrosamines can vary in their carcinogenicity, with two potent carcinogens, N‐nitrosodiethylamine (NDEA) and N- nitrosodimethylamine (NDMA), often used as indicators of nitrosamine presence (Xxxxx, 2011). The World Health Organization (WHO), the European Union, and the US Environmental Protection Agency (EPA) classify NDEA and NDMA as probable or presumed human carcinogens (Xxxxx, 2011). The US Department of Health and Human Services released the 13th Report on Carcinogens in 2014, which included 15 listings of nitrosamines classified as “known or reasonably anticipated” carcinogens (NTP, 2014). Nitrosamines are linked with the development of multiple different types of cancer in many different animal modelsmatter to them, including colon tumors sexual violence. I do this work in male rats, female mice and guinea pigs, as well as cervical tumors in female shrews following rectal or oral administration (NTP, 2014). Nitrosamines have been found in food, cosmetics, tobacco products, and rubber goods such as balloons, pacifiers, baby bottle teats, and also condoms (NTP, 2007; Dong et alhonor of you., 2015; Altkofer et al., 2005; Fritschi et al., 2015; Xxxxxxxx & Xxxxxxxxxxxx, 2011). Nitrosamine-related cancer studies in humans are relatively scarce, though they include epidemiological studies of cancer mortality for occupational cohorts, as well as case-control or ecological studies conducted on dietary exposure (Monarca et al., 2001; de Vocht et al., 2007; NTP, 2014). Subsequent sections will discuss studies and regulations regarding nitrosamine exposure in occupational settings, food and drinking water, as well as rubber products like pacifiers, rubber gloves, and condoms1. The migration of nitrosamines from condoms to mucous membranes like the vagina and rectum, which have higher absorption, is a possible risk (Eisenbrand, 2005).

TABLE OF CONTENTS INTRODUCTION 1 BACKGROUND 3 METHODS 8 RESULTS 19 DISCUSSION 24 CONCLUSIONS 33 REFERENCES 34 INTRODUCTION‌ End-stage renal disease (ESRD) has increased by 1000% in the past 3 decades, proving to be a significant health concern in the United Sates. In 1980, there were 60,000 persons with ESRD though in 2018 there were over 700,000 Americans living with ESRD (1). The expense of Chronic Kidney Disease (CKD) and ESRD has a significant impact on the United States economy and in 2018, CKD and ESRD accounted for mapping approximately 7% of Medicare expenditure, equating to $114 billion per year (2,3). It is well established that kidney transplantation is the optimal therapy for ESRD as it provides increased survival, better quality of life, and GISis less costly when compared with conventional dialysis (4–7). Since the advent of effective antiretroviral therapy, persons living with HIV (PLWH) are surviving longer and accumulating comorbidities. While HIV specific mortality has decreased, unfortunately, there continues to be a growing HIV epidemic, particularly in the southeastern United States. In 2017, the south accounted for 52% of the 38,739 new HIV diagnoses (8). As the HIV population ages, ESRD has emerged as a significant cause of morbidity and mortality, with PLWH being three times more likely to develop ESRD compared with the general population and is thought to compromise approximately 1.5% of the dialysis population (9,10). Additionally, compared with HIV- negative counterparts, PLWH experience a lower one- and five- year survival on dialysis (11). Despite this, there is growing evidence that PLWH are less likely to be placed on the organ waitlist and 47% less likely to receive a living donor kidney transplant (12). In order to improve survival and increase transplant rates among PLWH, it is critical to better understand the barriers to achieving a kidney transplant in this high-risk population. The objective of this thesis project was to identify and describe the HIV positive dialysis population in ESRD Network 6, the region with the lowest rates of kidney transplantation in the nation. Additionally, to compare their progression through the early steps (referral, evaluation, and waitlisting) of kidney transplantation to general dialysis population, and highlight patient and dialysis level characteristics that may influence access to kidney transplantation. This was accomplished through creating a novel HIV-ESRD dataset that identifies PLWH as well as her encyclopedic knowledge in finding those who proceeded through the early steps of transplantation.

The widespread use of affective antiretroviral therapy (ART) has decreased the prevalence of HIV-associated nephropathies (13,14), playing roles in human immunodeficiency however, PLWH are still developing CKD and ESRD faster than HIV negative counterparts. This is largely due to co-morbidities (diabetes mellitus, cardiovascular disease, hypertension, and metabolic syndrome), co- infection with hepatitis C virus (HIV) prevention, prevention of sexually transmitted infections (STIsHCV), medication induced injury, and family planning. There has been substantial investment by local governments, international health agencies and non- governmental organizations accelerated aging seeing in chronic HIV infection (NGOs) to increase supply and uptake of condoms (Xxxxxx et al., 2016; Xxxxxxx et al., 2008; Pienaar et al., 2016; Xxxxx et al., 20159,15,16). Increasing PLWH of black race are especially at risk for progression from CKD to ESRD. A study performed in Baltimore, Maryland revealed that African-Americans were at an increased risk for incident CKD and developed ESRD markedly faster than white subjects (HR, 17.7 [95% CI 2.5-127.0]) (17). ESRD among PLWH is particularly present in the southeast. In 2000, ESRD Network 6 had the 4th highest percentage of PLWH on dialysis at a proportion of 1.9% compared to an national average of 1.5%(10). Unfortunately, the southeastern region of the US continues to have the highest burden of CKD and ESRD with Georgia, North Carolina and South Carolina being states with some of the highest age-standardized CKD disability-adjusted life years (18,19). This coupled by the ongoing HIV epidemic in the southeast makes ESRD Network 6 a unique region to study the coexistence of ESRD and access to condoms kidney transplantation among PLWH. With significant risk of progression from CKD to ESRD, it is imperative to understand access to transplantation among this vulnerable patient population. Renal transplantation is a feasible treatment option for PLWH with ESRD. In the 1980’s, HIV infection was considered a contraindication for transplantation and education about STI and US legal code was amended to make it a federal crime to transplant tissue from HIV prevention has resulted in important gains in condom use, especially among high-risk populations like commercial sex workers positive donors (CSW) and men who have sex with men (MSM) (Xxxxxxx et al., 2008; Xxxxxx & Xxxxx, 2016; Xxxxxxxx et al., 2016; Subramanian et al., 201320). HoweverIt was theorized that the effect of immunosuppression would contribute to progression of HIV disease, condom usage among CSWs continues lead to face barriers including client preference for unprotected sexmore episodes of infection and increased rate of death; making it an inappropriate allocation of an organ. Between 1987 to 1997, inconsistent condom supply, and policies that criminalize sex work (Xxxxxxxx et al., 2016; Jung, 2013). Among MSM populations, condom use is mediated by perceptions of risk and condom self-efficacy (Xxxxxx & Xxxxx, 2016; Xxxxxxxxxx et al., 2016; Jung, 2013). National rates of condom use there were 32 kidney transplants performed in the US vary in PLWH (mostly unintentional transplantation), with reported 3-year graft survival of 53% and patient survival 83% (21,22). These transplants though were prior to significant improvement in medications used to treat PLWH. In 2003, Xxxxx et al published promising outcomes on 14 HIV-positive patients who underwent transplantation. At a mean follow up of 480 days, 10 out of 10 (100%) of patients who received kidney transplants were alive with functioning grafts. There was no evidence of HIV disease progression and HIV did not seem to have an impact on graft survival (23). Around the same time, driven out of lack of access to dialysis, colleagues in South Africa performed the first kidney transplants from HIV-positive organ donors to HIV-positive recipients, showing that transplantation among PLWH was safe and feasible (24). With revived interest in transplanting PLWH, there have been a number of single center studies and a large multicenter study of 150 HIV-positive renal transplant recipients which all reported transplant outcomes for PLWH that were similar to the general transplant population 19(25–28). With better HIV care and improved understanding of medication interactions, PLWH in the United States are not only eligible for HIV-negative organs, but HIV-positive organs as well. In 2013, the HIV Organ Procurement Equity (HOPE) Act was signed into law, reversing the 1988 amendment, allowing HIV positive organs to be transplanted into HIV positive recipients. This policy change is estimated to increase the donor pool by race300-500 organs, ageproviding a unique opportunity to increase utilization of these organs and increase rates of kidney transplantation in HIV positive individuals 20(29). The transplant evaluation process is a multifaceted and complex process with the southeastern region performing the least transplants. Though it is possible for patients to be referred for kidney transplant prior to starting dialysis, genderthe majority of ESRD patients start on dialysis before they are referred to a transplant center. Within 60 days of starting dialysis, patients are required by law to be educated on the risks and benefits of transplantation and if eligible, are referred by a dialysis provider to a transplant center. The transplant center then decides on their waitlist candidacy through conducting thorough medical evaluations (often inclusive of multiple studies and specialty evaluations), performing a psychosocial evaluation, assessing their social support network and financial ability to fund kidney transplantation. When this step is completed, the patient can be waitlisted with the eventual hope of receiving a living or deceased donor kidney transplant. To better understand how well dialysis facilities were performing in referring patients to kidney transplant, Xx. Xxxxxx Xxxxxx (co-I; Department of Surgery & Department of Epidemiology) and team reported in 2014 that ESRD Network 6 has the lowest rates of kidney transplantation in the nation, and sex actthat Georgia had the lowest of all 50 states (18,30,31) (Figure 1). Factors associated with decreased access to transplant include demographic differences in the southeast, racial disparities, socioeconomic influences, distance to transplant center, provider knowledge and awareness of transplantation (18,32,33). Because no national surveillance data exist on steps prior to waitlisting, the Southeastern Kidney Transplant Coalition developed a novel data registry for referral and evaluation for transplantation among all 9 transplant centers in Xxxxxxx, Xxxxx Xxxxxxxx xxx Xxxxx Xxxxxxxx (X00XX000000, PI: 24.7Xxxxxx). They found substantial variability in transplant access at the dialysis facility level where some facilities referred 0% of men patients and 21.8others referred 76% of women report condom use at last vaginal intercourse while 26.5% of insertive male partners, 44.1% of receptive male partners and 10.8% of receptive female partners report condom use at last anal intercourse (Reece et al., 201034). One Dialysis facility variability in transplant rates for HIV patients have not been described because currently no data exists linking HIV and ESRD care within a state or region. Factors influencing referral to kidney transplantation in PLWH have yet to be described in ESRD Network 6 and will direct construction of future interventions. Identifying PLWH who are on dialysis is difficult to do. Since 2005, there are scarce data on the barriers to condom usage incidence and prevalence of PLWH requiring dialysis. As part of a condition of participation in lowthe ESRD Medicare program, Centers for Medicare and Medicaid Services (CMS) medical evidence form (CMS 2728 form) is completed on every ESRD patient upon initiation of dialysis. CMS funds dialysis for ESRD patient and the surgical procedure and immunosuppressants for those who undergo kidney transplantation. The medical evidence form provides evidence of an ESRD condition, registers patients into a national renal registry, documents medical co-income countries is negative perception or rumors about condoms morbidities and other clinical data in dialysis patients, and ensures quality care for ERSD patients (Xxxxxxx et al., 2004); a study in Tanzania found that negative beliefs about condoms were significant predictors of willingness to use condoms (Xxxxxxx et al., 201235). Perceptions by In 2005, HIV serostatus was removed as an ESRD-related condition on the public about condom safety and efficacy directly affect their use and thus can adversely affect sexual and reproductive health programs medical evidence form due to concerns regarding disclosure of HIV status (Xxxxx et al., 2014; Xxxxxxx et al., 201236). Negative beliefs about condoms include the belief that condoms cause cancer Presently, in order to identity PLWH on dialysis, HIV status is inferred through pharmacy prescription data (Xxxxxxx et al., 201212). This ascertainment method is actually a concern among some condom manufacturers —specificallysuboptimal, as it may misclassify patients on pre-exposure prophylaxis as being on ART, may fail to identify PLWH not engaged in HIV care, and lacks patient-level epidemiologic and clinical data. Nonetheless, pharmacy prescription data is the release of nitrosamines from condoms (ISO/TC 157, 2015). Nitrosamines are a class of carcinogenic compounds only currently available method that can be produced used. In this study, Medicare prescription part D claims data was used to identify PLWH on dialysis. In 2016, there was 81% participation of Medicare part D among hemodialysis patients, suggestive that majority of the HIV population is captured in this study (37). METHODS‌ Hypothesis: Persons living with HIV in ESRD Network 6 are less likely to traverse through the multistep process of kidney transplantation compared to HIV-negative counterparts in the manufacturing process setting of rubber productsESRD. Formed by Specific Aims Aim 1: To identify and describe the reaction characteristics of nitrites with secondary or tertiary aminesPLWH and ESRD in ESRD Network 6. Aim 2: To describe the distribution and timing of early steps of kidney transplant inclusive of referral, nitrosamines can vary in their carcinogenicity, with two potent carcinogens, N‐nitrosodiethylamine (NDEA) and N- nitrosodimethylamine (NDMA), often used as indicators of nitrosamine presence (Xxxxx, 2011). The World Health Organization (WHO), the European Unionevaluation, and the US Environmental Protection Agency (EPA) classify NDEA waitlisting among PLWH compared with HIV negative individuals with ESRD in Network 6. Aim 3: To identify patient-level and NDMA as probable or presumed human carcinogens (Xxxxx, 2011). The US Department of Health dialysis facility-level factors that are associated with time to referral and Human Services released the 13th Report on Carcinogens in 2014, which included 15 listings of nitrosamines classified as “known or reasonably anticipated” carcinogens (NTP, 2014). Nitrosamines are linked with the development of multiple different types of cancer in many different animal models, including colon tumors in male rats, female mice and guinea pigs, as well as cervical tumors in female shrews following rectal or oral administration (NTP, 2014). Nitrosamines have been found in food, cosmetics, tobacco products, and rubber goods such as balloons, pacifiers, baby bottle teats, and also condoms (NTP, 2007; Dong et altime to waitlisting., 2015; Altkofer et al., 2005; Fritschi et al., 2015; Xxxxxxxx & Xxxxxxxxxxxx, 2011). Nitrosamine-related cancer studies in humans are relatively scarce, though they include epidemiological studies of cancer mortality for occupational cohorts, as well as case-control or ecological studies conducted on dietary exposure (Monarca et al., 2001; de Vocht et al., 2007; NTP, 2014). Subsequent sections will discuss studies and regulations regarding nitrosamine exposure in occupational settings, food and drinking water, as well as rubber products like pacifiers, rubber gloves, and condoms1. The migration of nitrosamines from condoms to mucous membranes like the vagina and rectum, which have higher absorption, is a possible risk (Eisenbrand, 2005).

Conclusions. The associations between food insecurity and diabetes as well as the high prevalence of both conditions give evidence that food insecurity should be addressed in clinical settings. This study finds no evidence indicating an association between nitrosamine exposure from condoms and incidence makes the case that electronic medical records should include measures of cervical and colorectal cancerfood insecurity for appropriate referral. Condoms provide substantial and measurable public health benefitsMore research, and providers and healthcare organizations should especially longitudinal, is necessary to continue to recommend examining this association.

There has been substantial investment by local governments, international health agencies and non- governmental organizations (NGOs) to increase supply and uptake of condoms (Xxxxxx et al., 2016; Xxxxxxx et al., 2008; Pienaar et al., 2016; Xxxxx et al., 2015). Increasing access to condoms and education about STI and HIV prevention has resulted in important gains in condom use, especially among high-risk populations like commercial sex workers (CSW) and men who have sex with men (MSM) (Xxxxxxx et al., 2008; Xxxxxx & Xxxxx, 2016; Xxxxxxxx et al., 2016; Subramanian et al., 2013). However, condom usage among CSWs cases continues to face barriers including client preference for unprotected sex, inconsistent condom supply, and policies grow. In that criminalize sex work (Xxxxxxxx et al., 2016; Jung, 2013). Among MSM populations, condom use is mediated by perceptions of risk and condom self-efficacy (Xxxxxx & Xxxxx, 2016; Xxxxxxxxxx et al., 2016; Jung, 2013). National rates of condom use in the US vary by race, age, gender, and sex act: 24.7% of men and 21.8% of women report condom use at last vaginal intercourse while 26.5% of insertive male partners, 44.1% of receptive male partners and 10.8% of receptive female partners report condom use at last anal intercourse (Reece et al., 2010). One of the barriers to condom usage in low-income countries is negative perception or rumors about condoms (Xxxxxxx et al., 2004); a study in Tanzania found that negative beliefs about condoms were significant predictors of willingness to use condoms (Xxxxxxx et al., 2012).

TB usually affects the lungs and is transmitted from human-printed sources cited 53 Introduction Condoms are one of the most important public health tools in sexual healthto-human through inhalation. The bacterium that is primarily responsible for causing TB, playing roles in human immunodeficiency virus Mycobacterium tuberculosis (HIV) prevention, prevention of sexually transmitted infections (STIsMTB), was first identified and family planningdescribed in 1882 by Xxxxxx Xxxx. There has been substantial investment Infections with MTB (MTBI) can be classified as either an active disease (referred to as TB) with clinical symptoms and pathological signs, or as an asymptomatic non-contagious state, often called “latent” TB infection (LTBI). People with TB may present with constitutional symptoms, such as weight loss, fever, chills, night sweats, and weakness, but may also present with symptoms associated with disease in specific organs. The lung is most often affected as evidence by local governmentssymptoms of cough, international health agencies sputum production, hemoptysis, and non- governmental organizations chest pain, that are typically accompanied by an abnormal chest x-ray. Pulmonary TB accounts for approximately 80% of newly diagnosed TB in the U. S. while 20% to 30% involves extra-pulmonary sites. Traditional methods used to diagnose TB rely primarily on sputum smear microscopy, bacteriological culture, and clinical examination, although newer and rapid molecular tests are being used with increasing frequency. A combination of sputum culture and clinical exam are considered the gold standard for definitive TB diagnosis. TB is curable with a standard six month course of four antimicrobial agents (NGOs) to increase supply isoniazid, rifampicin, pyrazinamide, and uptake ethambutol), but, if left untreated, 70% of condoms cases worldwide will not survive 10 years (Xxxxxx et al.World Health Organization, 2016; Xxxxxxx et al., 2008; Pienaar et al., 2016; Xxxxx et al., 2015). Increasing access to condoms and education about STI and HIV prevention has resulted in important gains in condom use, especially among high-risk populations like commercial sex workers (CSW) and men who have sex with men (MSM) (Xxxxxxx et al., 2008; Xxxxxx & Xxxxx, 2016; Xxxxxxxx et al., 2016; Subramanian et al., 2013). However, condom usage among CSWs continues to face barriers including client preference for unprotected sex, inconsistent condom supply, and policies that criminalize sex work (Xxxxxxxx et al., 2016; Jung, 2013). Among MSM populations, condom use is mediated by perceptions of risk and condom self-efficacy (Xxxxxx & Xxxxx, 2016; Xxxxxxxxxx et al., 2016; Jung, 2013). National rates of condom use in the US vary by race, age, gender, and sex act: 24.7% of men and 21.8% of women report condom use at last vaginal intercourse while 26.5% of insertive male partners, 44.1% of receptive male partners and 10.8% of receptive female partners report condom use at last anal intercourse (Reece et al., 2010). One of the barriers to condom usage in low-income countries is negative perception or rumors about condoms (Xxxxxxx et al., 2004); a study in Tanzania found that negative beliefs about condoms were significant predictors of willingness to use condoms (Xxxxxxx et al., 2012). Perceptions by the public about condom safety and efficacy directly affect their use and thus can adversely affect sexual and reproductive health programs (Xxxxx et al., 2014; Xxxxxxx et al., 2012). Negative beliefs about condoms include the belief that condoms cause cancer (Xxxxxxx et al., 2012). This is actually a concern among some condom manufacturers —specifically, the release of nitrosamines from condoms (ISO/TC 157, 2015). Nitrosamines are a class of carcinogenic compounds that can be produced in the manufacturing process of rubber products. Formed by the reaction of nitrites with secondary or tertiary amines, nitrosamines can vary in their carcinogenicity, with two potent carcinogens, N‐nitrosodiethylamine (NDEA) and N- nitrosodimethylamine (NDMA), often used as indicators of nitrosamine presence (Xxxxx, 2011). The World Health Organization (WHO), the European Union, and the US Environmental Protection Agency (EPA) classify NDEA and NDMA as probable or presumed human carcinogens (Xxxxx, 2011). The US Department of Health and Human Services released the 13th Report on Carcinogens in 2014, which included 15 listings of nitrosamines classified as “known or reasonably anticipated” carcinogens (NTP, 2014). Nitrosamines are linked with the development of multiple different types of cancer in many different animal models, including colon tumors in male rats, female mice and guinea pigs, as well as cervical tumors in female shrews following rectal or oral administration (NTP, 2014). Nitrosamines have been found in food, cosmetics, tobacco products, and rubber goods such as balloons, pacifiers, baby bottle teats, and also condoms (NTP, 2007; Dong et al., 2015; Altkofer et al., 2005; Fritschi et al., 2015; Xxxxxxxx & Xxxxxxxxxxxx, 2011). Nitrosamine-related cancer studies in humans are relatively scarce, though they include epidemiological studies of cancer mortality for occupational cohorts, as well as case-control or ecological studies conducted on dietary exposure (Monarca et al., 2001; de Vocht et al., 2007; NTP, 2014). Subsequent sections will discuss studies and regulations regarding nitrosamine exposure in occupational settings, food and drinking water, as well as rubber products like pacifiers, rubber gloves, and condoms1. The migration of nitrosamines from condoms to mucous membranes like the vagina and rectum, which have higher absorption, is a possible risk (Eisenbrand, 2005).

Condoms provide substantial and measurable public health benefits, and providers and healthcare organizations should continue to recommend and promote them without hesitation. Lack of ecological association between state-level cervical and colorectal cancer incidence and nitrosamine exposure from condom use for a cross-sectional study gaps in the TIC practices of the TC. We put forth recommendations that build upon center strengths and address the identified barriers to facilitate the creation of a multilevel implementation strategy to integrate TIC into the HIV services provided. If successfully adapted, the TC could serve as a HIV-TIC model for other high-volume, resource- constrained HIV clinics.

This is actually a concern among some condom manufacturers —specifically, the release of nitrosamines from condoms (ISO/TC 157, 2015). Nitrosamines are a class of carcinogenic compounds that can be produced in the manufacturing process of rubber products. Formed by the reaction of nitrites with secondary or tertiary amines, nitrosamines can vary in their carcinogenicity, with two potent carcinogens, N‐nitrosodiethylamine (NDEA) and N- nitrosodimethylamine (NDMA), often used as indicators of nitrosamine presence (Xxxxx, 2011). The World Health Organization (WHO), the European Union, and the US Environmental Protection Agency (EPA) classify NDEA and NDMA as probable or presumed human carcinogens (Xxxxx, 2011). The US Department of Health and Human Services released the 13th Report on Carcinogens in 2014, which included 15 listings of nitrosamines classified as “known or reasonably anticipated” carcinogens (NTP, 2014). Nitrosamines are linked with the development of multiple different types of cancer in many different animal models, including colon tumors in male rats, female mice and guinea pigs, as well as cervical tumors in female shrews following rectal or oral administration (NTP, 2014). Nitrosamines have been found in food, cosmetics, tobacco products, and rubber goods such as balloons, pacifiers, baby bottle teats, and also condoms (NTP, 2007; Dong et al., 2015; Altkofer et al., 2005; Fritschi et al., 2015; Xxxxxxxx & Xxxxxxxxxxxx, 2011). Nitrosamine-related cancer studies in humans are relatively scarce, though they include epidemiological studies of cancer mortality for occupational cohorts, as well as case-control or ecological studies conducted on dietary exposure (Monarca et al., 2001; de Vocht et al., 2007; NTP, 2014). Subsequent sections will discuss studies and regulations regarding nitrosamine exposure in occupational settings, food and drinking water, as well as rubber products like pacifiers, rubber gloves, and condoms1. The migration of nitrosamines from condoms to mucous membranes like the vagina and rectum, which have higher absorption, is a possible risk (Eisenbrand, 2005).
