RESUMEN

BACKGROUND: At-risk levels of alcohol use threaten the health of patients with HIV (PWH), yet evidence-based strategies to decrease alcohol use and improve HIV-related outcomes in this population are lacking. We examined the effectiveness of integrated stepped alcohol treatment (ISAT) on alcohol use and HIV outcomes among PWH and at-risk alcohol use. METHODS: In this multi-site, randomized trial conducted between January 28, 2013 through July 14, 2017, we enrolled PWH and at-risk alcohol use [defined as alcohol consumption of ≥ 14 drinks per week or ≥ 4 drinks per occasion in men ≤ 65 years old or ≥ 7 drinks per week or ≥ 3 drinks per occasion in women or men > 65 years old]. ISAT (n = 46) involved: Step 1- Brief Negotiated Interview with telephone booster, Step 2- Motivational Enhancement Therapy, and Step 3- Addiction Physician Management. Treatment as usual (TAU) (n = 47) involved receipt of a health handout plus routine care. Analyses were conducted based on intention to treat principles. RESULTS: Despite a multi-pronged approach, we only recruited 37% of the target population (n = 93/254). Among ISAT participants, 50% advanced to Step 2, among whom 57% advanced to Step 3. Participants randomized to ISAT and TAU had no observed difference in drinks per week over the past 30 days at week 24 (primary outcome) [least square means (Ls mean) (95% CI) = 8.8 vs. 10.6; adjusted mean difference (AMD) (95% CI) = - 0.4 (- 3.9, 3.0)]. CONCLUSION: An insufficient number of patients were interested in participating in the trial. Efforts to enhance motivation of PWH with at-risk alcohol use to engage in alcohol-related research and build upon ISAT are needed. Trial registration Clinicaltrials.gov: NCT01410123, First posted August 4, 2011.

RESUMEN

BACKGROUND: There is no known safe level of alcohol use among patients with HIV and liver disease. We examined the effectiveness of integrated stepped alcohol treatment (ISAT) on alcohol use, HIV, and liver outcomes among patients with HIV and liver disease. METHODS: In this multi-site, randomized trial conducted between January 28, 2013 through July 15, 2016, we enrolled 95 patients with HIV and liver disease [defined as having active hepatitis C infection or FIB-4 score > 1.45]. ISAT (n = 49) involved: Step 1- Brief Negotiated Interview with telephone booster, Step 2- Motivational Enhancement Therapy, and Step 3- Addiction Physician Management. Treatment as usual (TAU) (n = 46) involved receipt of a health handout plus routine care. Analyses were conducted based on intention to treat. RESULTS: Among ISAT participants, 55% advanced to Step 2, among whom 70% advanced to Step 3. Participants randomized to ISAT and TAU increased abstinence (primary outcome) over time. Abstinence rates were non-significantly higher by self-report (38% vs. 23%, adjusted odds ratio [AOR] [95% CI] = 2.6 [0.8, 9.0]) and phosphatidylethanol (43% vs. 32%, AOR [95% CI] = 1.8 [0.5, 6.3] among those randomized to ISAT vs. TAU at week 24. VACS Index scores (AMD [95% CI] = 1.1 [-3.2, 5.5]) and the proportion with an undetectable HIV viral load (AOR [95% CI] = 0.3 [0.1, 1.3]) did not differ by group at week 24 (p values >0.05). ISAT had non-significantly lower FIB-4 scores (adjusted mean difference [AMD] [95% CI] = -0.2 [-0.9, 0.5]), ALT (AMD [95% CI] = -7 [-20, 7]) and AST (AMD [95% CI] = -4 [-15, 7]) at week 24 compared to TAU. CONCLUSION: ISAT is feasible and potentially effective at enhancing delivery of evidence-based alcohol treatment to promote alcohol abstinence and improve liver biomarkers among patients with HIV and liver disease.

RESUMEN

PURPOSE: Trauma has been associated with risky sexual behavior in diverse populations. However, little is known about this association among men and women veterans. This study hypothesized that 1) a history of trauma would be associated with risky sexual behavior among men and women veterans, 2) interpersonal trauma would predict risky sexual behavior among women, whereas noninterpersonal trauma would predict risky sexual behavior among men, and 3) military-related trauma would constitute additional risk. Using data from 567 women and 524 men veterans enrolled at the Veterans Health Administration, this study investigated the association between trauma-related experiences and risky sexual behavior in the last 12 months. Risk and protective factors that have been frequently associated with sexual behavior in previous research were also included in the model. METHODS: This study was drawn from the Women Veterans Cohort Study, a national survey of veterans. Bivariate and multivariate analyses were performed after multiple imputation for missing data. RESULTS: Predictive factors associated with risky sexual behavior differed between men and women veterans. Among women, childhood sexual victimization and intimate partner violence were associated with risky sexual behavior. Among men, binge drinking was the single significant risk factor. Military exposures were not significantly associated with risky sexual behavior in either men or women. CONCLUSIONS: This study lays the groundwork for theory-generating research into the psychological underpinnings of noted associations and underscores the importance of integrated health services to address the range of issues affecting sexual behavior and related health outcomes.

RESUMEN

CONTEXT: It has been assumed that the increase in urine calcium (Ca) that accompanies an increase in dietary protein was due to increased bone resorption. However, studies using stable Ca isotopes have found that dietary protein increases Ca absorption without increasing bone resorption. OBJECTIVE: The objective of the study was to investigate the impact of a moderately high protein diet on bone mineral density (BMD). DESIGN: This was a randomized, double-blind, placebo-controlled trial of protein supplementation daily for 18 months. SETTING: The study was conducted at two institutional research centers. PARTICIPANTS: Two hundred eight older women and men with a body mass index between 19 and 32 kg/m(2) and a self-reported protein intake between 0.6 and 1.0 g/kg participated in the study. INTERVENTION: Subjects were asked to incorporate either a 45-g whey protein or isocaloric maltodextrin supplement into their usual diet for 18 months. MAIN OUTCOME MEASURE: BMD by dual-energy x-ray absorptiometry, body composition, and markers of skeletal and mineral metabolism were measured at baseline and at 9 and 18 months. RESULTS: There were no significant differences between groups for changes in L-spine BMD (primary outcome) or the other skeletal sites of interest. Truncal lean mass was significantly higher in the protein group at 18 months (P = .048). C-terminal telopeptide (P = .0414), IGF-1 (P = .0054), and urinary urea (P < .001) were also higher in the protein group at the end of the study period. There was no difference in estimated glomerular filtration rate at 18 months. CONCLUSION: Our data suggest that protein supplementation above the recommended dietary allowance (0.8 g/kg) may preserve fat-free mass without adversely affecting skeletal health or renal function in healthy older adults.

RESUMEN

CONTEXT: Excess abdominal adiposity is a primary factor for insulin resistance in older age. OBJECTIVES: Our objectives were to examine the role of abdominal obesity on adipose tissue, hepatic, and peripheral insulin resistance in aging, and to examine impaired free fatty acid metabolism as a mechanism in these relations. DESIGN: This was a cross-sectional study. SETTING: The study was performed at a General Clinical Research Center. PARTICIPANTS: Healthy, inactive older (>60 yr) women (n = 25) who were not on hormone replacement therapy or glucose-lowering medication were included in the study. Women with abdominal circumference values above the median (>97.5 cm) were considered abdominally obese. MAIN OUTCOME MEASURES: Whole-body peripheral glucose utilization, adipose tissue lipolysis, and hepatic glucose production were measured using in vivo techniques according to a priori hypotheses. RESULTS: In the simple analysis, glucose utilization at the 40 mU insulin dose (6.3 +/- 2.8 vs. 9.1 +/- 3.4; P < 0.05), the index of the insulin resistance of basal hepatic glucose production (23.6 +/- 13.0 vs. 15.1 +/- 6.0; P < 0.05), and insulin-stimulated suppression of lipolysis (35 vs. 54%; P < 0.05) were significantly different between women with and without abdominal obesity, respectively. Using the glycerol appearance rate to free fatty acid ratio as an index of fatty acid reesterification revealed markedly blunted reesterification in the women with abdominal adiposity under all conditions: basal (0.95 +/- 0.29 vs. 1.35 +/- 0.47; P < 0.02); low- (2.58 +/- 2.76 vs. 6.95 +/- 5.56; P < 0.02); and high-dose (4.46 +/- 3.70 vs. 12.22 +/- 7.13; P < 0.01) hyperinsulinemia. Importantly, fatty acid reesterification was significantly (P < 0.01) associated with abdominal circumference and hepatic and peripheral insulin resistance, regardless of total body fat. CONCLUSION: These findings support the premise of dysregulated fatty acid reesterification with abdominal obesity as a pathophysiological link to perturbed glucose metabolism across multiple tissues in aging.

RESUMEN

CONTEXT: The role of magnesium (Mg) as a determinant of bone mass has not been extensively explored. Limited studies suggest that dietary Mg intake and bone mineral density are correlated in adults, but no data from interventional studies in children and adolescents are available. OBJECTIVE: We sought to determine whether Mg supplementation in periadolescent girls enhances accrual of bone mass. DESIGN: We carried out a prospective, placebo-controlled, randomized, one-year double-blind trial of Mg supplementation. SETTING: The study was conducted in the Clinical Research Centers at Yale University School of Medicine. PATIENTS OR OTHER PARTICIPANTS: Healthy 8- to 14-yr-old Caucasian girls were recruited from community pediatricians' offices. Dietary diaries from over 120 volunteers were analyzed, and those with dietary Mg intake of less than 220 mg/d were invited to participate in the intervention. INTERVENTION: Magnesium (300 mg elemental Mg per day in two divided doses) or placebo was given orally for 12 months. MAIN OUTCOME MEASURE: The primary outcome measure was interval change in bone mineral content (BMC) of the total hip, femoral neck, Ward's area, and lumbar spine (L1-L4) after 12 months of Mg supplementation. RESULTS: Significantly increased accrual (P = 0.05) in integrated hip BMC occurred in the Mg-supplemented vs. placebo group. Trends for a positive Mg effect were evident in the pre- and early puberty and in mid-late puberty. Lumbar spinal BMC accrual was slightly (but not significantly) greater in the Mg-treated group. Compliance was excellent; 73% of capsules were ingested as inferred by pill counts. Serum mineral levels, calciotropic hormones, and bone markers were similar between groups. CONCLUSIONS: Oral Mg oxide capsules are safe and well tolerated. A positive effect of Mg supplementation on integrated hip BMC was evident in this small cohort.
