Increased Risk of Fragility Fractures among HIV Infected Compared to Uninfected Male Veterans

BACKGROUND: HIV infection has been associated with an increased risk of fragility fracture. We explored whether or not this increased risk persisted in HIV infected and uninfected men when controlling for traditional fragility fracture risk factors. METHODOLOGY/PRINCIPAL FINDINGS: Cox regression models were used to assess the association of HIV infection with the risk for incident hip, vertebral, or upper arm fracture in male Veterans enrolled in the Veterans Aging Cohort Study Virtual Cohort (VACS-VC). We calculated adjusted hazard ratios comparing HIV status and controlling for demographics and other established risk factors. The sample consisted of 119,318 men, 33% of whom were HIV infected (34% aged 50 years or older at baseline, and 55% black or Hispanic). Median body mass index (BMI) was lower in HIV infected compared with uninfected men (25 vs. 28 kg/m²; p<0.0001). Unadjusted risk for fracture was higher among HIV infected compared with uninfected men [HR: 1.32 (95% CI: 1.20, 1.47)]. After adjusting for demographics, comorbid disease, smoking and alcohol abuse, HIV infection remained associated with an increased fracture risk [HR: 1.24 (95% CI: 1.11, 1.39)]. However, adjusting for BMI attenuated this association [HR: 1.10 (95% CI: 0.97, 1.25)]. The only HIV-specific factor associated with fragility fracture was current protease inhibitor use [HR: 1.41 (95% CI: 1.16, 1.70)]. CONCLUSIONS/SIGNIFICANCE: HIV infection is associated with fragility fracture risk. This risk is attenuated by BMI

Changing patterns in the prevalence of posttraumatic stress disorder, major depressive episode and generalized anxiety disorder over 24 months following a road traffic crash: Results from the UQ SuPPORT study.

OBJECTIVE: To examine the prevalence and changing patterns of PTSD, major depressive episode (MDE), and generalized anxiety disorder (GAD) in adult claimants who sustained a non-catastrophic injury in a road traffic crash (RTC) in Queensland, Australia. METHOD: Participants (N = 284) were assessed at approximately 6, 12, and 24 months post-RTC using the composite international diagnostic interview (CIDI) modules for PTSD, and CIDI-short form for MDE, and GAD. RESULTS: The prevalence of at least one of these disorders was 48.2%, 52.5%, and 49.3%, at 6, 12, and 24 months, respectively. Comorbidity was common (20.8% at 6 months, 27.1% at 12 months, and 21.1% at 24 months) and only 33.1% of participants never met PTSD, GAD, or MDE criteria. A substantial proportion of participants (42.3%) had an unstable diagnostic pattern over time. Participants with multiple diagnoses at 6 months were more likely to continue to meet diagnostic criteria for any disorder at 12 and 24 months than participants with a single diagnosis. Participants with PTSD (with or without MDE/GAD) were more likely to meet criteria for any disorder at 24 months than participants with another diagnosis. Preinjury psychiatric history increased the likelihood of any disorder at 24 months post-injury, but did not significantly increase the likelihood of PTSD. CONCLUSIONS: People injured in a RTC are at risk of having complex psychological presentations over time. Interventions to prevent mental disorders, especially PTSD, in the early post-injury period are needed to prevent chronic psychological injury, including consideration of comorbidity and dynamic course

Decreased Awareness of Current Smoking Among Health Care Providers of HIV-positive Compared to HIV-negative Veterans

BACKGROUND: Cigarette smoking is an important risk factor for morbidity and mortality in HIV-positive patients on combination antiretroviral therapy. OBJECTIVE: To determine whether awareness of smoking differs between HIV and non-HIV providers, and to identify factors associated with failure to recognize current smoking. DESIGN: Observational study. PARTICIPANTS: 801 HIV-positive and 602 HIV-negative patients, 72 HIV and 71 non-HIV providers enrolled in the Veterans Aging Cohort 5 Site Study. MEASUREMENTS: Data sources included patient and provider questionnaires; electronic medical records; and the national administrative VA database. We calculated sensitivity, specificity, and measures of agreement between patient- and provider-reported smoking, and examined factors associated with failure to recognize current smoking using logistic regression. RESULTS: Whereas most providers were correct when they identified a patient as a current smoker (specificity ≥90%), HIV providers missed current smoking more often (sensitivity 65% for HIV vs. 82% for non-HIV). Kappa scores for current smoking were significantly lower for HIV compared to non-HIV providers (0.55 vs. 0.75, p\u3c.001). In models adjusted for age, gender, race, and other differences, patient HIV status and provider specialty in infectious diseases were independent predictors of a provider\u27s failure to recognize current smoking. Comorbid illnesses, cough/dyspnea, degree of immune competence and HIV viral suppression did not impact recognition of current smoking. Only 39% of HIV providers reported confidence in their ability to influence smoking cessation compared to 62% of non-HIV providers (p=.049). CONCLUSIONS: Interventions to increase HIV provider awareness of current smoking and skills to influence smoking cessation are needed. Efforts should also target patient populations with smoking-related comorbid diseases who would especially benefit from smoking cessation. © 2007 Society of General Internal Medicine

The Unique Challenges Facing HIV-Positive Patients Who Smoke Cigarettes: HIV Viremia, Art Adherence, Engagement in HIV care, and Concurrent Substance Use

Evidence suggests that smoking may have negative associations with HIV health outcomes. The smoking rate in our sample of people living with HIV (N = 333) was triple that of the general population (57% v. 19%). Regression analyses revealed that smokers (v. non-smokers) reported lower medication adherence (unstandardized beta = 9.01) and were more likely to have a detectable viral load (OR = 2.85, 95%CI [1.53–5.30]). Smokers attended fewer routine medical visits (β = −0.16) and were more likely to report recent hospitalization (OR = 1.89, 95%CI [0.99, 3.57]). Smokers ranked “health” as less important to their quality of life (β = −0.13) and were more likely to report problematic alcohol (OR = 2.40, 95%CI [1.35, 4.30]), cocaine (OR = 2.87, 95%CI [1.48–5.58]), heroin (OR = 4.75, 95%CI [1.01, 22.30]), or marijuana use (OR = 3.08, 95%CI [1.76–5.38]). Findings underscore the need for integrated behavioral smoking cessation interventions and routine tobacco screenings in HIV primary care
