Patient characteristics. Two comparisons were made for the purposes of this inves- tigation: (1) patients with bacteriuria vs nonbacteriuria control subjects (Table 1), and (2) UTI vs ASB subjects (Table 2). All 296 study subjects were white. ■ Patients with bacteriuria vs control subjects —When com- pared with individuals from the nonbacteriuria control group ( Table 1), patients with bacteriuria (either UTI or ASB) were more often: ▫ female (84% vs 75%; OR, 1.84; 95% CI, 1.03-3.26) ▫ nursing home residents (OR, 1.74; 95% CI, 1.08-2.80) ▫ had a history of hypertension (OR, 1.81; 95% CI, 1.14-2.87) ▫ received bladder catheterization in the ED or on admission (OR, 1.72; 95% CI, 1.08-2.74) JAOA • Vol 109 • No 4 • April 2009 • 221 ORIGINAL CONTRIBUTION Table 1 Bacteriuria in Hospitalized Older Adults: Characteristics and Acute Discharge Diagnosis for Subjects With Bacteriuria vs Nonbacteriuria Control Subjects (N=296)* Characteristics Bacteriuria Group (n=154) Nonbacteriuria Control Group (n=142) Crude Odds Ratio (95% Confidence Interval) ■ Mean (SD) Age, y 83 (8) 82 (8) ... ■ Female 130 (84) 106 (75) 1.84 (1.03-3.26)† ■ Nursing Home Resident 68 (44) 47 (33) 1.74 (1.08-2.80)† ■ Medical History ▫ Cognitive impairment 47 (31) 38 (27) 1.20 (0.73-1.99) ▫ Cardiovascular health – Hypertension 93 (60) 65 (46) 1.81 (1.14-2.87)† – Stroke 30 (19) 34 (24) 0.77 (0.44-1.34) ▫ Pulmonary disease – Chronic obstructive pulmonary disease 33 (21) 36 (25) 0.80 (0.47-1.38) – Pneumonia 16 (10) 19 (13) 0.75 (0.37-1.52) ▫ Diabetes mellitus 45 (29) 34 (24) 1.31 (0.78-2.20) ▫ Falls 16 (10) 9 (6) 1.71 (0.73-4.01) ■ Hospital Care‡ ▫ Bladder catheter 78 (51) 53 (37) 1.72 (1.08-2.74)† ▫ Antibiotic treatment 92 (60) 67 (47) 1.66 (1.05-2.63) † – Levofloxacin treament 53 (58) 26 (39) 2.09 (1.10-3.96)† Acute Discharge Diagnosis ■ Ischuria§ 5 (4) 11 (8) 0.44 (0.15-1.31) ■ Delirium 46 (30) 11 (8) 5.07 (2.51-10.27)† ■ Cardiovascular Health ▫ Atrial fibrillation 19 (12) 19 (13) 0.91 (0.46-1.80) ▫ Congestive heart failure 31 (20) 18 (13) 1.74 (0.92-3.27) ■ Pulmonary Disease 42 (27) 59 (42) 0.53 (0.32-0.86)† ▫ Pneumonia 23 (15) 32 (23) 0.60 (0.33-1.09) ■ Diabetes Mellitus With Hyperglycemia 32 (21) 27 (19) 1.12 (0.63-1.98) ■ Falls 26 (17) 20 (14) 1.24 (0.66-2.33) ▫ Fracture 8 (5) 12 (8) 0.59 (0.23-1.50) ▫ No fracture 18 (12) 8 (6) 2.22 (0.93-5.27) ■ Blood Test Results ▫ Serum urea nitrogen/ creatinine ratio, “20:1 79 (51) 68 (48) 1.15 (0.73-1.81) ▫ Electrolyte panel (imbalance) 51 (33) 58 (41) 0.72 (0.45-1.15) ▫ Serum albu...
Patient characteristics. A total of 299 patients (79%) participating in the GIPS-III trial underwent 2D TTE assessment, image quality was insufficient to determine LV mass in 9 subjects and to determine LV volumes in 38 subjects. CMR was performed in 275 patients (73%), image quality was insufficient to determine LV mass in 8 subjects and to determine LV volumes in 4 subjects. CMR and 2D TTE measurements were available in 259 patients (61%), of which LV mass measurements in both imaging modalities were available in 255 patients and LV volume measurements in 236 patients. In-hospital clinical, angiographic and biochemical characteristics, as well as medication at discharge, are presented in Table 1. Median infarct size was 7.2% (2.6, 13.7) of LV mass.
Patient characteristics. Data are expressed as the median (range). The mild asthmatics prior to challenge (n=11) are included in the total of 21 mild asthmatics.
Patient characteristics. Between 2010 and 2012, a total of 12,529 patients received at least one platelet transfusion in Denmark. Of these, 826 patients were excluded based on age at time of transfusion and 1,927 patients were excluded as they only received a transfusion in a hospital that accounted for fewer than 1000 platelet transfusions in the study period. The final cohort consisted of 9,776 patients, more men than women (62.3% versus 37.7%), with an average age of 64.1 years (table 1). During the study period, these patients received 66,101 platelet transfusions, of which 22,240 units (33.6%) were stored for six or seven days. This relatively large proportion of old platelet concentrates is a consequence of the first-in-first-out policy. Forty-nine percent of all platelet concentrates were transfused to patients with a hematological malignancy, 15.6% to patients with trauma or xxxxx, and 8.6% to patients who underwent cardiothoracic surgery. The distribution of diagnoses was similar among the storage time categories. Information about blood group of the product was missing for 11,156 products, but this was equally distributed among the storage time categories. The proportion of rhesus D negative products increased with increasing storage time (Table 2). Table 1.

Patient characteristics. A cohort of 3,513 DLBCL patients was identified, including 922 patients (26%) >80 years old at diagnosis. The mean and median ages at diagnosis in the sub-cohort of patients >80 years old were 85 and 84 years, respectively. The corresponding mean and median estimate for those ≤80 years of age was 73 years. Characteristics of patients in each age category are displayed in Table 1. Compared to patients ≤80 years old, those >80 years old were more likely to be female, widowed, live in a metropolitan area, have extranodal disease, and have poor performance status; patients >80 years old were less likely to have late stage disease and to live in a census tract with >25% of residents completing high school only (all p<0.05).
Patient characteristics. Patient characteristics are given in Table 1. The age of the subjects varied from 13 to 77 years, with the average of 43 years by the time of taking the CT scans (Table 1). 23 (40%) of the patients were men. 29 (51%) of the whole group had allergic rhinitis, 13 (23%) had diagnosed asthma and 13 (23%) had nasal polyps (Table 1). 35 out of 57 patients ended up having sinonasal surgery during the following 12 months after they had undergone sinus CT scans (Table 1). The regularly used medications excluding those for CRS or related diseases were for heart and vascular diseases (10 patients), hypothyreosis (5 patients), migraine (3 patients), hyper-cholesterolemia (2 patients), gastroesophageal reflux disease (2 patients), cystitis (1 patient), irritable bowel syndrome (1 patient), melanoma (1 patient), otosclerosis (1 patient), prostate hypertrophy (1 patient) and rheumatoid arthritis (1 patient). The median (min-max) duration of CRS symptoms was 8.3 (0-54 years) prior to taking the CT scan (Table 1). The median (min-max) number of antibiotic courses for acute rhinosinusitis during the past two years was 4.8 (0-15) (Table 1). The median VAS scores of sinonasal symptoms were between 3.5-5.8 (Table 1). 46 (81%) of the patients had current use of intranasal corticosteroids. None of the patients reported as having used peroral corticosteroids during the past 12 months (Table 1). 12 (21%) of the patients had undergone a previous sinus operation such as inferior or middle meatal antrostomy and/or ethmoidectomy (Table 1). The median (Q1-Q3) total Lund-MacKay score was 3 (1-5) on both sides (Table 2). Inter-observer agreement
Patient characteristics. Patient demographics including age, gender, screening height and weight, and other demographic characteristics will be summarized using descriptive statistics. Baseline disease characteristics will be summarized by presenting frequency counts and percentages for disease characteristics as appropriate.
Patient characteristics. ECG analysis was performed by LEADS (Leiden ECG Analysis and Decompo- sition Software), our MATLAB (The MathWorks, Natick, USA) program for re- search oriented ECG analysis. LEADS first computed an averaged beat in order to minimize noise. In this averaged beat, the beginning and end of the QRS complex were automatically detected. An observer, who was blinded to the patient data, cor- rected this interval if necessary. LEADS identified the apex and end of the T wave in each ECG lead. The end of the T wave was set at the point where the tangent to the steepest portion of the terminal part of the T wave crossed the isoelectric line. Subsequently, LEADS searched backward for the apex of the T wave, defined as the point of the T wave with the highest amplitude. Finally, LEADS calculated a num- ber of ECG indices proposed to assess dispersion of the repolarization: the Tapex- end interval8, QT interval12, T-wave amplitude13, T-wave surface area14 and T-wave complexity15. QT and Tapex-end intervals were corrected for heart rate by the Bazett formula16. T-wave complexity was calculated by means of singular value decomposi- tion of the T wave15;17. The higher, more complex, singular values 2 to 8 were divided by the first, most simple component to quantify T-wave complexity. Additionally, LEADS constructed the vectorcardiogram by using the inverse Dower matrix18;19 and calculated the spatial angle between the QRS and T axes.
Patient characteristics. Forty-seven patients (53.2% female, median age 62 years, range 22-74 years) and 47 healthy controls (76.6% female, median age 54 years, range 24-66 years) were vaccinated with the seasonal influenza vaccine from October to December 2016. Healthy controls were significantly younger (p=0.001) and were more frequently female (p=0.02) than the MG group. In the MG group, 23 patients randomly received a placebo injection followed by flu vaccination 4 weeks later. Baseline characteristics did not differ between the two MG patients groups that either received first the flu vaccination or the placebo vaccination. The MG group consisted of 29 patients with (IM+) and 18 without (IM-) immunosuppressive medication. The IM+ group was significantly older (p<0.01) than the IM- group and contained more female patients (p=0.04). Disease duration and whether a patient underwent a thymectomy in the past was not significantly different between IM- and IM+ groups (p=0.4 and p=0.16, respectively). Baseline characteristics are given in Table 1.
