Do medical house officers value the health of veterans differently from the health of non-veterans?

BACKGROUND: Little information is available regarding medical residents' perceptions of patients' health-related quality of life. Patients cared for by residents have been shown to receive differing patterns of care at Veterans Affairs facilities than at community or university settings. We therefore examined: 1) how resident physicians value the health of patients; 2) whether values differ if the patient is described as a veteran; and 3) whether residency-associated variables impact values. METHODS: All medicine residents in a teaching hospital were asked to watch a digital video of an actor depicting a 72-year-old patient with mild-moderate congestive heart failure. Residents were randomized to 2 groups: in one group, the patient was described as a veteran of the Korean War, and in the other, he was referred to only as a male. The respondents assessed the patient's health state using 4 measures: rating scale (RS), time tradeoff (TTO), standard gamble (SG), and willingness to pay (WTP). We also ascertained residents' demographics, risk attitudes, residency program type, post-graduate year level, current rotation, experience in a Veterans Affairs hospital, and how many days it had been since they were last on call. We performed univariate and multivariable analyses using the RS, TTO, SG and WTP as dependent variables. RESULTS: Eighty-one residents (89.0% of eligible) participated, with 36 (44.4%) viewing the video of the veteran and 45 (55.6%) viewing the video of the non-veteran. Their mean (SD) age was 28.7 (3.1) years; 51.3% were female; and 67.5% were white. There were no differences in residents' characteristics or in RS, TTO, SG and WTP scores between the veteran and non-veteran groups. The mean RS score was 0.60 (0.14); the mean TTO score was 0.80 (0.20); the mean SG score was 0.91 (0.10); and the median (25th, 75th percentile) WTP was $10,000 ($7600, $20,000) per year. In multivariable analyses, being a resident in the categorical program was associated with assigning higher RS scores, but no residency-associated variables were associated with the TTO, SG or WTP scores. CONCLUSION: Physicians in training appear not to be biased either in favor of or against military veterans when judging the value of a patient's health

Impact of HIV/AIDS on care and outcomes of severe sepsis

INTRODUCTION: There has been dramatic improvement in survival for patients with HIV/AIDS; however, some studies on patients with HIV/AIDS and serious illness have reported continued low rates of intensive care. The purpose of this study was to examine patterns of care and outcomes for patients with severe sepsis and HIV/AIDS and compare them with those of patients with severe sepsis without HIV/AIDS. METHODS: We assessed data from all 1999 discharge abstracts from all non-federal hospitals in six US states. Patient demographic characteristics, discharge diagnoses, resource use, and outcomes were extracted. Analyses were performed using chi-square, Wilcoxon rank sum, or regression techniques, as appropriate. RESULTS: We identified 74,020 patients with severe sepsis (7,638 (10.3%) had HIV/AIDS) using ICD-9-CM codes. Patients with severe sepsis and HIV/AIDS had a similar mean length of stay (16.9 days versus 17.7 days; p = 0.0669), had lower mean hospitalization cost ($24,382 versus$30,537; p < 0.0001), were less likely to be admitted to the intensive care unit (37% versus 56%; p < 0.0001), and had a greater mortality (29% versus 20%; p < 0.0001) than those without HIV/AIDS. After adjustment for cohort differences, patients with severe sepsis and HIV/AIDS had increased likelihood of death (OR (95% CI) = 2.41 (2.23–2.61)) and were substantially less likely to be admitted to the intensive care unit (OR (95% CI) = 0.54 (0.51–0.59)). When compared with those with severe sepsis and HIV/AIDS, patients with severe sepsis without HIV/AIDS were universally more likely to be admitted to the intensive care unit, even when they had comorbid illnesses with equal or worse expected in-hospital mortality (e.g., metastatic cancer). CONCLUSION: For patients with severe sepsis, there are differences in care and outcomes for those with HIV/AIDS. Further research is needed to examine the delivery of care for patients with severe sepsis and HIV/AIDS

Gender differences in health-related quality of life of adolescents with cystic fibrosis

BACKGROUND: Female patients with cystic fibrosis (CF) have consistently poorer survival rates than males across all ages. To determine if gender differences exist in health-related quality of life (HRQOL) of adolescent patients with CF, we performed a cross-section analysis of CF patients recruited from 2 medical centers in 2 cities during 1997–2001. METHODS: We used the 87-item child self-report form of the Child Health Questionnaire to measure 12 health domains. Data was also collected on age and forced expiratory volume in 1 second (FEV(1)). We analyzed data from 98 subjects and performed univariate analyses and linear regression or ordinal logistic regression for multivariable analyses. RESULTS: The mean (SD) age was 14.6 (2.5) years; 50 (51.0%) were female; and mean FEV(1 )was 71.6% (25.6%) of predicted. There were no statistically significant gender differences in age or FEV(1). In univariate analyses, females reported significantly poorer HRQOL in 5 of the 12 domains. In multivariable analyses controlling for FEV(1 )and age, we found that female gender was associated with significantly lower global health (p < 0.05), mental health (p < 0.01), and general health perceptions (p < 0.05) scores. CONCLUSION: Further research will need to focus on the causes of these differences in HRQOL and on potential interventions to improve HRQOL of adolescent patients with CF

Self-rated health of primary care house officers and its relationship to psychological and spiritual well-being

<p/> <p>Background</p> <p>The stress associated with residency training may place house officers at risk for poorer health. We sought to determine the level of self-reported health among resident physicians and to ascertain factors that are associated with their reported health.</p> <p>Methods</p> <p>A questionnaire was administered to house officers in 4 residency programs at a large Midwestern medical center. Self-rated health was determined by using a health rating scale (ranging from 0 = death to 100 = perfect health) and a Likert scale (ranging from "poor" health to "excellent" health). Independent variables included demographics, residency program type, post-graduate year level, current rotation, depressive symptoms, religious affiliation, religiosity, religious coping, and spirituality.</p> <p>Results</p> <p>We collected data from 227 subjects (92% response rate). The overall mean (SD) health rating score was 87 (10; range, 40–100), with only 4 (2%) subjects reporting a score of 100; on the Likert scale, only 88 (39%) reported excellent health. Lower health rating scores were significantly associated (P < 0.05) with internal medicine residency program, post-graduate year level, depressive symptoms, and poorer spiritual well-being. In multivariable analyses, lower health rating scores were associated with internal medicine residency program, depressive symptoms, and poorer spiritual well-being.</p> <p>Conclusion</p> <p>Residents' self-rated health was poorer than might be expected in a cohort of relatively young physicians and was related to program type, depressive symptoms, and spiritual well-being. Future studies should examine whether treating depressive symptoms and attending to spiritual needs can improve the overall health and well-being of primary care house officers.</p

Long-acting injectable Cabotegravir + Rilpivirine for HIV maintenance therapy: Week 48 pooled analysis of phase 3 ATLAS and FLAIR trials

BACKGROUND: Long-acting (LA) injectable regimens are a potential therapeutic option in people living with HIV-1. SETTING: ATLAS (NCT02951052) and FLAIR (NCT02938520) were 2 randomized, open-label, multicenter, multinational phase 3 studies. METHODS: Adult participants with virologic suppression (plasma HIV-1 RNA &lt;50 copies/mL) were randomized (1:1) to continue with their current antiretroviral regimen (CAR) or switch to the long-acting (LA) regimen of cabotegravir (CAB) and rilpivirine (RPV). In the LA arm, participants initially received oral CAB + RPV once-daily for 4 weeks to assess individual safety and tolerability, before starting monthly injectable therapy. The primary endpoint of this combined analysis was antiviral efficacy at week 48 (FDA Snapshot algorithm: noninferiority margin of 4% for HIV-1 RNA ≥50 copies/mL). Safety, tolerability, and confirmed virologic failure (2 consecutive plasma HIV-1 RNA ≥200 copies/mL) were secondary endpoints. RESULTS: The pooled intention-to-treat exposed population included 591 participants in each arm [28% women (sex at birth), 19% aged ≥50 years]. Noninferiority criteria at week 48 were met for the primary (HIV-1 RNA ≥50 copies/mL) and key secondary (HIV-1 RNA &lt;50 copies/mL) efficacy endpoints. Seven individuals in each arm (1.2%) developed confirmed virologic failure; 6/7 (LA) and 3/7 (CAR) had resistance-associated mutations. Most LA recipients (83%) experienced injection site reactions, which decreased in incidence over time. Injection site reactions led to the withdrawal of 6 (1%) participants. The serious adverse event rate was 4% in each arm. CONCLUSION: This combined analysis demonstrates monthly injections of CAB + RPV LA were noninferior to daily oral CAR for maintaining HIV-1 suppression

Compartmentation of Hexokinase in Rat Heart A Critical Factor for Tracer Kinetic Analysis of Myocardial Glucose Metabolism

Radiolabeled analogues of 2-deoxyglucose are widely used to trace glucose metabolism in cell cultures, whole organs, and intact animals, although kinetic differences in transport and phosphorylation between these compounds and glucose exist. The present studies were undertaken to determine the effects of insulin stimulation on the phosphorylation of 2-deoxyglucose compared to glucose in the intact, saline-perfused working rat heart. Rates of glucose utilization determined from tritiated glucose differed from rates estimated from the accumulation of I &apos;CI 2-deoxyglucose in a nonconstant manner when comparing rates in the absence or presence of physiologic levels of insulin (13 pU/ml). The fraction of monophosphorylated hexoses that was accounted for by [&apos;4C]2-deoxyglucose 6-phosphate was dramatically decreased in hearts perfused in the presence of insulin. Additionally, hexokinase activity associated with the mitochondrial fraction of tissue extracts was increased in hearts stimulated by insulin. While this redistribution of hexokinase to the mitochondria did not affect the apparent affinity constant for glucose, hexokinase bound to mitochondria exhibited an 8.5-fold decrease in the affinity for 2-deoxyglucose when compared with hexokinase present in the cytosolic fraction. The findings are consistent with an insulin-mediated preferential uptake and phosphorylation of glucose compared to deoxyglucose. The results also imply that the redistribution of hexokinase and the differential effect of insulin on its affinity for tracer and tracee are responsible for changes in the &quot;lumped constant &quot; (i.e., the correction factor used to equate 2-deoxyglucose to glucose uptake). These changes must be taken into account when regional myocardial glucose metabolism is assessed by the 2-deoxyglucose method. (J. Clin. Invest. 1992
