ABSTRACT
BACKGROUND: Antibiotic use remains common for the treatment of lower respiratory tract infections. The objective of this study was to evaluate the impact of antibiotic use on the duration and severity of acute lower respiratory tract infection (LRTI). PARTICIPANTS: Adult patients presenting to US primary or urgent care sites with a chief complaint of cough and symptoms consistent with LRTI. MAIN MEASURES: Collected data included demographics, comorbidities, symptoms, and 48 viral and bacterial respiratory pathogens by PCR. Severity of signs/symptoms was reported for up to 28 days using diaries and text messages. Interpolation was used where data were missing. KEY RESULTS: Of 718 patients with baseline data, 29% had an antibiotic prescribed at baseline. The most common antibiotics were amoxicillin-clavulanate, azithromycin, doxycycline, and amoxicillin in 85% of patients. Provision of an antibiotic had no effect on the duration or overall severity of cough, including in patients with viral, bacterial, and mixed infections. Receipt of an antibiotic did reduce the likelihood of a follow-up visit (14.1% vs 8.2%, aOR 0.47, 95% CI 0.26-0.84), perhaps by removing the motivation of getting an antibiotic at a follow-up visit. However, they were also more likely to receive a systemic corticosteroid (31.9% vs 4.5%, p < 0.001) and were also more likely to receive an albuterol inhaler (22.7% vs 7.6%, p < 0.001). Patients believed that receiving an antibiotic would reduce the duration of their illness by nearly 4 days. CONCLUSIONS: In this large prospective study in the US primary and urgent care setting, antibiotics had no measurable impact on the severity or duration of cough due to acute LRTI. Patients had unrealistic expectations regarding the duration of LRTI and the effect of antibiotics which should be the target of antibiotic stewardship efforts.

BACKGROUND: Social unacceptability of food access is part of the lived experience of food insecurity but is not assessed as part of the United States Household Food Security Survey Module (HFSSM). OBJECTIVES: The objectives were as follows: 1) to determine the psychometric properties of 2 additional items on social unacceptability in relation to the HFSSM items and 2) to test whether these 2 items provided added predictive accuracy to that of the HFSSM items for mental health outcomes. METHODS: Cross-sectional data used were from the Intersection of Material-Need Insecurities and HIV and Cardiovascular Health substudy of the Multicenter AIDS Cohort Study/Women's Interagency HIV Study Combined Cohort Study. Data on the 10-item HFSSM and 2 new items reflecting social unacceptability were collected between Fall 2020 and Fall 2021 from 1342 participants from 10 United States cities. The 2 social unacceptability items were examined psychometrically in relation to the HFSSM-10 items using models from item response theory. Linear and logistic regression was used to examine prediction of mental health measured by the 20-item Center for Epidemiologic Studies Depression scale and the 10-item Perceived Stress Scale. RESULTS: The social unacceptability items were affirmed throughout the range of severity of food insecurity but with increasing frequency at higher severity of food insecurity. From item response theory models, the subconstructs reflected in the HFSSM-10 and the subconstruct of social unacceptability were distinct, not falling into one dimension. Regression models confirmed that social unacceptability was distinct from the subconstructs reflected in the HFSSM-10. The social unacceptability items as a separate scale explained more (â¼1%) variation in mental health than when combined with the HFSSM-10 items in a single scale, and the social unacceptability subconstruct explained more (â¼1%) variation in mental health not explained by the HFSSM-10. CONCLUSIONS: Two social unacceptability items used as a separate scale along with the HFSSM-10 predicted mental health more accurately than did the HFSSM-10 alone.

Context: Probiotics are live microorganisms that, when administered in adequate amounts, confer a health benefit on the host. One of the most common indications for probiotic treatment is the prevention of antibiotic-associated diarrhea (AAD). Unfortunately, many probiotic products used for AAD are not supported by rigorous independent research, and often results in non-evidence-based usage. Additionally, it is not clear when is the most appropriate time to take a probiotic when on an antibiotic course. Objectives: The primary aim is to determine the ability of BB-12 to impact antibiotic-induced reduction in short chain fatty acid concentration (SCFA), as reflected by the levels of acetate on day 14. Secondarily to determine the ability of BB-12 to impact antibiotic-induced disruption of the gut microbiota with 16S rDNA profiling, with the addition of the time variable of probiotic consumption. Study Design and Interventions: A five group randomized controlled trial, finished in December 2022, we are currently analyzing all the data, but will be finished much prior to NAPCRG. All participants were given a 7-day prescription for amoxicillin-clavulanic acid 875mg taken twice daily. One group received no other interventions. While the other participants were broken into 4 groups. Two groups consumed the yogurt intervention (either yogurt+probiotic or control yogurt) four hours after the antibiotic and two groups consumed the yogurt intervention (either yogurt+probiotic or control yogurt) concomitantly with antibiotics. This timing question is important, as it is unknown if the optimal time for patients to administer probiotics is concurrently with, or after four hours following antibiotic consumption. Setting: Capital Areal Primary Care Practice Based Research Network. Population Studied: 118 participants, ages 18-65 years, generally healthy. Outcome Measures: Change in SCFA among the five groups, microbiome reduced disruption and clinically diagnosed diarrhea. Results: Study is complete and analysis is underway. Should have full results by end of July 2023, much before NAPCRG. .

Context: Probiotics are live microorganisms that, when administered in adequate amounts, confer a health benefit on the host. One of the most common indications for probiotic treatment is the prevention of antibiotic-associated diarrhea (AAD). Unfortunately, many probiotic products used for AAD are not supported by rigorous independent research, and often results in non-evidence-based usage. The overarching objective is to move research forward for the most well-studied Bifidobacterium strain. Objectives: The primary aim is to test the efficacy of high dose, BB-12-supplemented yogurt in preventing AAD, compared to yogurt without BB-12, in children receiving antibiotics. Other aims are to further assess the safety of yogurt supplemented with BB-12, and to carry out longitudinal community structure and gene expression analysis of fecal microbiota to evaluate the impact of high dose BB-12 in a pediatric population receiving antibiotics. The microbiota includes hundreds of species, and its disruption is hypothesized to be an important factor in the development of AAD. AIM 1: To test the efficacy of high dose, BB-12-supplemented yogurt in preventing AAD, compared to yogurt without BB-12, in children receiving antibiotics. Hypothesis: Children receiving antibiotics who receive the yogurt with BB-12 will demonstrate less diarrhea than those receiving a control yogurt without BB-12. This is a Phase II trial that requires additional safety evaluation of high dose BB-12. Hypotheses 3: Administration of antibiotics will alter the composition and gene expression profile of the gut microbiota in pediatric patients, and concomitant ingestion of BB-12 in yogurt will mitigate the antibiotic-induced disturbance in the gut microbiota, as identified using 16S rRNA and metatranscriptomic profiling. Study Design and Analysis: We will finish in the June 2023 a Phase II, randomized, doubleblinded controlled trial with allocation concealment. Setting: Capital Areal Primary Care Practice Based Research Network. Population Studied: 270 patients, ages 3-12 years, clinically diagnosed with a respiratory infection requiring 7-10 days of antibiotics. Interventions: The two arms are, BB-12-supplemented yogurt and non-supplemented control yogurt, in a 1:1 randomized allocation. Participants of all ages will be asked to consume the same dose, 100 ml, of product per day. The 100 ml serving of probiotic yogurt will deliver ≥1010 CFU of BB-12. The BB-12 probiotic was not be added.

Long COVID (LongC) is associated with a myriad of symptoms including cognitive impairment. We reported at the beginning of the COVID-19 pandemic that neuronal-enriched or L1CAM+ extracellular vesicles (nEVs) from people with LongC contained proteins associated with Alzheimer's disease (AD). Since that time, a subset of people with prior COVID infection continue to report neurological problems more than three months after infection. Blood markers to better characterize LongC are elusive. To further identify neuronal proteins associated with LongC, we maximized the number of nEVs isolated from plasma by developing a hybrid EV Microfluidic Affinity Purification (EV-MAP) technique. We isolated nEVs from people with LongC and neurological complaints, AD, and HIV infection with mild cognitive impairment. Using the OLINK platform that assesses 384 neurological proteins, we identified 11 significant proteins increased in LongC and 2 decreased (BST1, GGT1). Fourteen proteins were increased in AD and forty proteins associated with HIV cognitive impairment were elevated with one decreased (IVD). One common protein (BST1) was decreased in LongC and increased in HIV. Six proteins (MIF, ENO1, MESD, NUDT5, TNFSF14 and FYB1) were expressed in both LongC and AD and no proteins were common to HIV and AD. This study begins to identify differences and similarities in the neuronal response to LongC versus AD and HIV infection.

OBJECTIVE: Sexual and physical abuse are highly prevalent among women living with HIV (WLWH) and are risk factors for the development of mental health and substance use disorders (MHDs, SUDs), and cognitive and medical comorbidities. We examined empirically derived patterns of trauma, MHD, and SUD, and associations with later cognitive and health outcomes. METHODS: A total of 1027 WLWH (average age = 48.6 years) in the Women's Interagency HIV Study completed the World Mental Health Composite International Diagnostic Interview from 2010 to 2013 to identify MHDs, SUDs, and age at onset of sexual and physical abuse. Then, cognitive impairment, cardiovascular/metabolic conditions, and HIV disease outcomes were assessed for up to 8.8 years. Latent class analysis identified patterns of co-occurring trauma, MHDs, and/or SUDs. Generalized estimating equations determined associations between these patterns and midlife cognitive and medical outcomes. RESULTS: Six distinct profiles emerged: no/negligible sexual/physical trauma, MHD, or SUD (39%); preadolescent/adolescent sexual trauma with anxiety and SUD (22%); SUD only (16%); MHD + SUD only (12%); early childhood sexual/physical trauma only (6%); and early childhood sexual/physical trauma with later MHD + SUD (4%). Profiles including early childhood trauma had the largest number of midlife conditions (i.e., cognitive, cardiovascular, HIV-related). Preadolescent/adolescent sexual trauma with anxiety and SUD predicted both global and domain-specific cognitive declines. Only SUD without trauma predicted lower CD4, whereas childhood trauma with MHD + SUD predicted increased CD8. CONCLUSIONS: WLWH have complex multisystem profiles of abuse, MHD, and/or SUD that predict midlife cognitive, metabolic/cardiovascular, and HIV outcomes. Understanding the interplay between these factors over time can identify risks and personalize preventative and treatment interventions.

BACKGROUND: Live dietary microbes have been hypothesized to contribute to human health but direct evidence is lacking. OBJECTIVES: This study aimed to determine whether the dietary consumption of live microbes is linked to improved health outcomes. METHODS: Data from the NHANES 2001-2018 were used to assess microbial intake and their adjusted associations with selected physiological parameters (e.g., blood pressure, anthropometric measures, and biomarkers) among adults aged 19 y and older. Regression models were constructed to assess the microbial intake with each physiological parameter and adjusted for demographics and other covariates. Microbial intake was assessed as both a continuous variable and a 3-level categorical variable. Fermented foods were assessed in a separate model. RESULTS: In continuous models, an additional 100-g intake of microbe-containing foods was associated with a lower systolic blood pressure (regression coefficient: -0.331; 95% CI: -0.447, -0.215 mm Hg), C-reactive protein (-0.013; 95% CI: -0.019, -0.008 mg/dL), plasma glucose -0.347; 95% CI: -0.570, -0.124 mg/dL), plasma insulin (-0.201; 95% CI: -0.304, -0.099 µU/mL), triglyceride (-1.389; 95% CI: -2.672, -0.106 mg/dL), waist circumference (-0.554; 95% CI: -0.679, -0.428 cm), and BMI -0.217; 95% CI: -0.273, -0.160 kg/m2) levels and a higher level of high density lipoprotein cholesterols (0.432; 95% CI: 0.289, 0.574 mg/dL). Patterns were broadly similar when microbial intake was assessed categorically and when fermented foods were assessed separately. CONCLUSIONS: To our knowledge, this study is the first to quantify, in a nationally representative data set of American adults and using stable sets of covariates in the regression models, the adjusted associations of dietary intakes of live microbes with a variety of outcomes, such as anthropometric measures, biomarkers, and blood pressure levels. Our findings suggest that foods with higher microbial concentrations are associated with modest health improvements across a range of outcomes.

Food insecurity disproportionately affects people with HIV and women in the United States (US). More evidence is needed to understand the interplay between levels of food insecurity and levels of antiretroviral therapy (ART) adherence over time, as well as how food insecurity relates to engagement in HIV care. We used random effects models with longitudinal data from the US Women's Interagency HIV Study to estimate the (1) adjusted associations of current and 6-month lagged food security with ART adherence categories (n = 1646), and (2) adjusted associations of food security with engagement-in-care (n = 1733). Very low food security was associated with a higher relative risk of ART non-adherence at prior and current visits compared with food security, and this association increased across non-adherence categories. Very low food security was associated with lower odds of receiving HIV care and higher odds of a missed visit. Food insecurity among US women with HIV is associated with poorer engagement in care and degree of ART non-adherence over time.

BACKGROUND: Consuming live microbes in foods may benefit human health. Live microbe estimates have not previously been associated with individual foods in dietary databases. OBJECTIVES: We aimed to estimate intake of live microbes in US children (aged 2-18 y) and adults (≥19 y) (n = 74,466; 51.2% female). METHODS: Using cross-sectional data from the NHANES (2001-2018), experts assigned foods an estimated level of live microbes per gram [low (Lo), <104 CFU/g; medium (Med), 104-107 CFU/g; or high (Hi), >107 CFU/g]. Probiotic dietary supplements were also assessed. The mean intake of each live microbe category and the percentages of subjects who ate from each live microbe category were determined. Nutrients from foods with live microbes were also determined using the population ratio method. Because the Hi category comprised primarily fermented dairy foods, we also looked at aggregated data for Med or Hi (MedHi), which included an expanded range of live microbe-containing foods, including fruits and vegetables. RESULTS: Our analysis showed that 52%, 20%, and 59% of children/adolescents, and 61%, 26%, and 67% of adults, consumed Med, Hi, or MedHi foods, respectively. Per capita intake of Med, Hi, and MedHi foods was 69, 16, and 85 g/d for children/adolescents, and 106, 21, and 127 g/d for adults, respectively. The proportion of subjects who consumed live microbes and overall per capita intake increased significantly over the 9 cycles/18-y study period (0.9-3.1 g/d per cycle in children across categories and 1.4 g/d per cycle in adults for the Med category). CONCLUSIONS: This study indicated that children, adolescents, and adults in the United States steadily increased their consumption of foods with live microbes between the earliest (2001-2002) and latest (2017-2018) survey cycles. Additional research is needed to determine the relations between exposure to live microbes in foods and specific health outcomes or biomarkers.

BACKGROUND: Food insecurity is associated with increased morbidity and mortality in people with human immunodeficiency virus (HIV) on antiretroviral therapy, but its relationship with immune dysregulation, a hallmark of HIV infection and comorbidity, is unknown. METHODS: In 241 women participating in the Women's Interagency HIV Study, peripheral blood mononuclear cells were characterized by flow cytometry to identify cell subsets, comprising surface markers of activation (%CD38+HLADR+), senescence (%CD57+CD28-), exhaustion (%PD-1+), and co-stimulation (%CD57- CD28+) on CD4+ and CD8+ T cells. Mixed-effects linear regression models were used to assess the relationships of food insecurity with immune outcomes, accounting for repeated measures at ≤3 study visits and adjusting for sociodemographic and clinical factors. RESULTS: At the baseline study visit, 71% of participants identified as non-Hispanic Black, 75% were virally suppressed, and 43% experienced food insecurity. Food insecurity was associated with increased activation of CD4+ and CD8+ T cells, increased senescence of CD8+ T cells, and decreased co-stimulation of CD4+ and CD8+ T cells (all Pâ <â .05), adjusting for age, race/ethnicity, income, education, substance use, smoking, HIV viral load, and CD4 count. In stratified analyses, the association of food insecurity with CD4+ T-cell activation was more pronounced in women with uncontrolled HIV (viral load >40 copies/mL and CD4 <500 cells/mm3) but remained statistically significant in those with controlled HIV. CONCLUSIONS: Food insecurity may contribute to the persistent immune activation and senescence in women with HIV on antiretroviral therapy, independently of HIV control. Reducing food insecurity may be important for decreasing non-AIDS-related disease risk in this population.

In 2019, the National Institutes of Health combined the Multicenter AIDS Cohort Study (MACS) and the Women's Interagency HIV Study (WIHS) into the MACS/WIHS Combined Cohort Study (MWCCS). In this paper, participants who made a study visit during October 2018-September 2019 (targeted for MWCCS enrollment) are described by human immunodeficiency virus (HIV) serostatus and compared with people living with HIV (PLWH) in the United States. Participants include 2,115 women and 1,901 men with a median age of 56 years (interquartile range, 48-63); 62% are PLWH. Study sites encompass the South (18%), the Mid-Atlantic/Northeast (45%), the West Coast (22%), and the Midwest (15%). Participant race/ethnicity approximates that of PLWH throughout the United States. Longitudinal data and specimens collected for 35 years (men) and 25 years (women) were combined. Differences in data collection and coding were reviewed, and key risk factor and comorbidity data were harmonized. For example, recent use of alcohol (62%) and tobacco (28%) are common, as are dyslipidemia (64%), hypertension (56%), obesity (42%), mildly or severely impaired daily activities (31%), depressive symptoms (28%), and diabetes (22%). The MWCCS repository includes serum, plasma, peripheral blood mononuclear cells, cell pellets, urine, cervicovaginal lavage samples, oral samples, B-cell lines, stool, and semen specimens. Demographic differences between the MACS and WIHS can confound analyses by sex. The merged MWCCS is both an ongoing observational cohort study and a valuable resource for harmonized longitudinal data and specimens for HIV-related research.

BACKGROUND: Food insecurity is a well-established determinant of suboptimal, self-reported antiretroviral therapy (ART) adherence, but few studies have investigated this association using objective adherence measures. We examined the association of food insecurity with levels of ART concentrations in hair among women living with human immunodeficiency virus (WLHIV) in the United States. METHODS: We analyzed longitudinal data collected semiannually from 2013 through 2015 from the Women's Interagency HIV Study, a multisite, prospective, cohort study of WLHIV and controls not living with HIV. Our sample comprised 1944 person-visits from 677 WLHIV. Food insecurity was measured using the US Household Food Security Survey Module. ART concentrations in hair, an objective and validated measure of drug adherence and exposure, were measured using high-performance liquid chromatography with mass spectrometry detection for regimens that included darunavir, atazanavir, raltegravir, or dolutegravir. We conducted multiple 3-level linear regressions that accounted for repeated measures and the ART medication(s) taken at each visit, adjusting for sociodemographic and clinical characteristics. RESULTS: At baseline, 67% of participants were virally suppressed and 35% reported food insecurity. In the base multivariable model, each 3-point increase in food insecurity was associated with 0.94-fold lower ART concentration in hair (95% confidence interval, 0.89 to 0.99). This effect remained unchanged after adjusting for self-reported adherence. CONCLUSIONS: Food insecurity was associated with lower ART concentrations in hair, suggesting that food insecurity may be associated with suboptimal ART adherence and/or drug absorption. Interventions seeking to improve ART adherence among WLHIV should consider and address the role of food insecurity.

The collective findings from human microbiome research, randomized controlled trials on specific microbes (i.e., probiotics), and associative studies of fermented dairy consumption provide evidence for the beneficial effects of the regular consumption of safe live microbes. To test the hypothesis that the inclusion of safe, live microbes in the diet supports and improves health, we propose assessment of the types and evidentiary quality of the data available on microbe intake, including the assembly and evaluation of evidence available from dietary databases. Such an analysis would help to identify gaps in the evidence needed to test this hypothesis, which can then be used to formulate and direct initiatives focused on prospective and randomized controlled trials on live microbe consumption. Outcomes will establish whether or not the evidence exists, or can be generated, to support the establishment of dietary recommendations for live microbes.

Background: Chronic inflammation is associated with AIDS-defining and non-AIDS-defining conditions. Limited research has considered how food insecurity influences chronic inflammation among people living with human immunodeficiency virus (HIV). We examined whether food insecurity was associated with higher levels of inflammation among women living with HIV (WWH) in the United States. Methods: We analyzed cross-sectional data collected in 2015 from 421 participants on antiretroviral therapy from the Women's Interagency HIV Study. The exposure was any food insecurity. The outcome was inflammation, measured by proinflammatory cytokine interleukin-6 (IL-6) and tumor necroses factor receptor 1 (TNFR1) levels. We conducted multivariable linear regressions, adjusting for sociodemographic, clinical, and nutritional factors. Results: Nearly one-third of participants (31%) were food insecure and 79% were virally suppressed (<20 copies/mL). In adjusted analyses, food insecurity was associated with 1.23 times the level of IL-6 (95% confidence interval [CI], 1.06-1.44) and 1.13 times the level of TNFR1 (95% CI, 1.05-1.21). Findings did not differ by HIV control (virally suppressed with CD4 counts ≥500 cells/mm3 or not) in adjusted stratified analyses. Conclusion: Food insecurity was associated with elevated inflammation among WWH regardless of HIV control. Findings support the need for programs that address food insecurity among WWH.

BACKGROUND: Food insecurity, which disproportionately affects marginalized women in the United States, is associated with depressive symptoms. Few studies have examined relations of food insecurity with other mental health outcomes. OBJECTIVE: The aim of this study was to investigate the associations of food insecurity with symptoms of generalized anxiety disorder (GAD), stress, and posttraumatic stress disorder (PTSD) in the Women's Interagency HIV Study (WIHS), a prospective cohort study of women with or at risk of HIV in the United States. METHODS: Participants were 2553 women with or at risk of HIV, predominantly African American/black (71.6%). Structured questionnaires were conducted during April 2013-March 2016 every 6 mo. Food security (FS) was the primary predictor, measured using the Household Food Security Survey Module. We measured longitudinal outcomes for GAD (GAD-7 score and a binary GAD-7 screener for moderate-to-severe GAD). Only cross-sectional data were available for outcomes measuring perceived stress (PSS-10 score) and PTSD (PCL-C score and a binary PCL-C screener for PTSD). We examined associations of FS with the outcomes through use of multivariable linear and logistic regression, including lagged associations with GAD outcomes. RESULTS: After adjusting for sociodemographic and health-related factors including HIV serostatus, current marginal, low, and very low FS were associated with increasingly higher GAD-7 scores, and with 1.41 (95% CI: 1.10, 1.80; P < 0.01), 2.03 (95% CI: 1.59, 2.61; P < 0.001), and 3.23 (95% CI: 2.43, 4.29; P < 0.001) times higher odds of screening positive for moderate-to-severe GAD, respectively. Low and very low FS at the previous visit (6 mo earlier) were independently associated with GAD outcomes at current visit. Associations of FS with PSS-10 and PCL-C scores exhibited similar dose-response relations. Very low FS was associated with 1.93 (95% CI: 1.15, 3.24; P < 0.05) times higher odds of screening positive for PTSD. CONCLUSIONS: Food insecurity may be associated with a range of poor mental health outcomes among women in the United States with or at risk of HIV.

BACKGROUND: Food insecurity and mental health negatively affect the lives of women in the United States. Participants in the Women's Interagency HIV Study (WIHS) provided the opportunity to understand the association of food insecurity with depression and mental well-being over time. OBJECTIVE: We investigated the association between current and persistent food insecurity and depression among women at risk of or living with HIV in the United States. METHODS: We used longitudinal data from the WIHS, a prospective cohort study in women at risk of or living with HIV from multiple sites in the United States. Participants completed 6 semiannual assessments from 2013 to 2016 on food security (FS; high, marginal, low, and very low) and mental health (i.e., depressive symptoms and mental well-being). We used multiple regression analysis to estimate the association between these variables. RESULTS: Among 2551 participants, 44% were food insecure and 35% reported depressive symptoms indicative of probable depression. Current marginal, low, and very low FS were associated with 2.1-, 3.5-, and 5.5-point (all P < 0.001) higher depression scores, respectively. In models adjusting for both current and previous FS, previous marginal, low, and very low FS were associated with 0.2-, 0.93-, and 1.52-point higher scores, respectively (all P < 0.001). Women with very low FS at both time points (persistent food insecurity) had a 6.86-point higher depression score (P < 0.001). In the mental health models, there was a dose-response relation between current FS and worse mental health even when controlling for previous FS (all P < 0.001). Previous low FS was associated with worse mental health. These associations did not differ by HIV status. CONCLUSIONS: Food insecurity placed women at risk of depression and poor mental well-being, but the risk was substantially higher for women experiencing persistent food insecurity. Future interventions to improve women's mental health call for multilevel components that include addressing food insecurity.

Research is scant regarding differential effects of specific types of recreational drugs use on antiretroviral therapy adherence among women, particularly to single-tablet regimens (STR). This is increasingly important in the context of marijuana legalization. We examined the effects of self-reported substance use on suboptimal (<95%) adherence in the Women's Interagency HIV Study, 2003-2014. Among 1799 HIV-infected women, the most prevalent substance used was marijuana. In multivariable Poisson GEE regression, substance use overall was significantly associated with suboptimal adherence (adjusted prevalence ratio, aPR = 1.20, 95% CI 1.10-1.32), adjusting for STR use, socio-demographic, behavioral, and clinical factors. Among STR users, compared to no drug use, substance use overall remained detrimental to ART adherence (aPR = 1.61, 95% CI 1.24-2.09); specifically, both marijuana (aPR = 1.48, 95% CI: 1.11-1.97) and other drug use (aPR = 1.87, 95% CI 1.29-2.70) predicted suboptimal adherence. These findings highlight the need to intervene with drug-using women taking antiretroviral therapy to maintain effective adherence.

We used the World Health Organization's Composite International Diagnostic Interview to determine the prevalence, comorbidity, and correlates of lifetime and 12-month behavioral health disorders in a multisite cohort of 1027 women living with HIV in the United States. Most (82.6%) had one or more lifetime disorders including 34.2% with mood disorders, 61.6% with anxiety disorders, and 58.3% with substance use disorders. Over half (53.9%) had at least one 12-month disorder, including 22.1% with mood disorders, 45.4% with anxiety disorders, and 11.1% with substance use disorders. Behavioral health disorder onset preceded HIV diagnosis by an average of 19 years. In multivariable models, likelihood of disorders was associated with women's race/ethnicity, employment status, and income. Women with 12-month behavioral health disorders were significantly more likely than their counterparts to engage in subsequent sexual and substance use HIV risk behaviors. We discuss the complex physical and behavioral health needs of women living with HIV.

Food insecurity, internalized HIV stigma, and depressive symptoms are independently associated with poor HIV outcomes. Food insecurity, stigma, and depression may be interrelated among women living with HIV (WLHIV). We hypothesized that food insecurity would be independently associated with internalized stigma and depressive symptoms among WLHIV in the United States (US), and would partially account for associations between stigma and depressive symptoms. We tested hypotheses using regression models and partial correlation analysis with cross-sectional data among 1317 WLHIV from the Women's Interagency HIV Study. In adjusted models, greater food insecurity was associated with internalized HIV stigma and depressive symptoms (all p < 0.05), exhibiting dose-response relationships. Food insecurity accounted for 23.2% of the total shared variance between depressive symptoms and internalized stigma. Food insecurity is associated with depressive symptoms and internalized HIV stigma among US WLHIV, and may play a role in the negative cycle of depression and internalized stigma.

BACKGROUND: There is pressure in the U.S. system to move away from fee-for-service models to a more pre-paid system, which may result in decreased costs, but the impact on evidence-based care is unclear. We examined a large pre-paid Health Maintenance Organizations (HMO) in Israel to see if evidence-based guidelines are followed for prostate specific antigen (PSA) testing. METHODS: A retrospective cohort of ambulatory visits from 2002 to 2011 of patients age >75 receiving care from Clalit Health Services was conducted. Historically reported U.S. cohorts were used for comparison. The main measure was the percent of patients who had at least one PSA after age 75. RESULTS: In each of the 10 years of follow-up, 22% of the yearly Israeli cohort, with no known malignancy or benign prostatic hyperplasia, had at least one PSA, while for the total 10 years, 30% of the men had at least one PSA. These rates are considerably lower than previously reported U.S. rates. CONCLUSIONS: In a pre-paid system in which physicians have no incentive to order tests, they appear to order PSA tests at a lower rate than has been observed in the U.S. system. Additional quality of measures should continue to be examined as the U.S. shifts away from a fee-for-service model. Copyright © 2016 John Wiley & Sons, Ltd.
