Clinically significant BE is related to poorer surgical outcomes, and additional interventions may be needed to improve long term outcomes. Though surgery does alter body's physiology, claims that the psychological aspects of BE are "cured" by obesity surgery must be viewed with caution. Researchers and practitioners must reach a consensus on how to define BE after gastric surgery so that future long-term prospective studies may further evaluate the effect of BE on surgical outcome and vice versa.

BackgroundMany lesbian and bisexual (LB) women veterans may have been targets of victimization in the military based on their gender and presumed sexual orientation, and yet little is known regarding the health or mental health of LB veterans, nor the degree to which they feel comfortable receiving care in the VA.ObjectiveThe purpose of this study was to examine the prevalence of mental health and gender-specific conditions, VA healthcare satisfaction and trauma exposure among LB veterans receiving VA care compared with heterosexually-identified women veterans receiving.DesignProspective cohort study of Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) women veterans at two large VA facilities.ParticipantsThree hundred and sixty five women veterans that completed a baseline survey. Thirty-five veterans (9.6 %) identified as gay or lesbian (4.7 %), or bisexual (4.9 %).Main MeasuresMeasures included sexual orientation, military sexual trauma, mental and gender-specific health diagnoses, and VA healthcare utilization and satisfaction.Key ResultsLB OEF/OIF veterans were significantly more likely to have experienced both military and childhood sexual trauma than heterosexual women (MST: 31 % vs. 13 %, p < .001; childhood sexual trauma: 60 % vs. 36 %, p = .01), to be hazardous drinkers (32 % vs. 16 %, p = .03) and rate their current mental health as worse than before deployment (35 % vs. 16 %, p < .001).ConclusionsMany LB veterans have experienced sexual victimization, both within the military and as children, and struggle with substance abuse and poor mental health. Health care providers working with female Veterans should be aware of high rates of military sexual trauma and childhood abuse and refer women to appropriate VA treatment and support groups for sequelae of these experiences. Future research should focus on expanding this study to include a larger and more diverse sample of lesbian, gay, bisexual, and transgender veterans receiving care at VA facilities across the country.

SUMMARY Background Treatment of hepatitis C virus (HCV) infection with pegylated interferon/ribavirin achieves sustained virological response in up to 56% of HCV mono-infected patients and 40% of HCV/human immunodeficiency virus (HIV)-co-infected patients. The relationship of patient adherence to outcome warrants study. Aim To review comprehensively research on patient-missed doses to HCV treatment and discuss applicable research from adherence to HIV antiretroviral therapy. Methods Publications were identified by PubMed searches using the keywords: adherence, compliance, hepatitis C virus, interferon and ribavirin. Results The term ‘non-adherence’ differs in how it is used in the HCV from the HIV literature. In HCV, ‘non-adherence’ refers primarily to dose reductions by the clinician and early treatment discontinuation. In contrast, in HIV, ‘non-adherence’ refers primarily to patient-missed doses. Few data have been published on the rates of missed dose adherence to pegylated interferon/ribavirin and its relationship to virological response. Conclusions As HCV treatment becomes more complex with new classes of agents, adherence will be increasingly important to treatment success as resistance mutations may develop with suboptimal dosing of HCV enzyme inhibitors. HIV adherence research can be applied to that on HCV to establish accurate methods to assess adherence, investigate determinants of non-adherence and develop strategies to optimize adherence.

Mortality in HIV-positive persons is increasingly due to non-HIV-related medical comorbidities. There are limited data on the prevalence and patient awareness of these comorbid conditions. Two hundred subjects at an urban HIV clinic were interviewed in 2005 to assess their awareness of 15 non-HIV-related medical comorbidities, defined as medical problems that are neither AIDS-defining by standard definitions, nor a direct effect of immune deficiency. Medical charts were subsequently reviewed to establish prevalence and concordance between selfreport and chart documentation. Eighty-four percent of subjects self-reported at least 1 of 15 medical comorbidities and 92% had at least 1 condition chart-documented. The top 5 chart-documented conditions were hepatitis C (51.5%), pulmonary disease (28.5%), high blood pressure (27%), high cholesterol (24.5%), and obesity (22.5%). In multivariate analysis, higher number of non-HIV-related medical comorbidities was associated with older age, female gender, and intravenous drug use as route of HIV transmission. Across self-reported non-HIV-related medical comorbidities, the absolute concordance rate ranged from 67% to 96%, the sensitivity ranged from 0% to 79%; the positive predictive value ranged from 0% to 100%. While the vast majority of largely urban minority HIVpositive subjects were diagnosed with non-HIV-related medical comorbidities, there is significant room for improvement in patient awareness. In order to help patients optimally access and adhere to medication and medical care for these non-HIV-related medical comorbidities, interventions and educational campaigns to improve patient awareness that take cultural background, literacy, and educational level into account should be developed, implemented, and evaluated.
