Plasma Glycomic Markers of Accelerated Biological Aging During Chronic HIV Infection.

People with HIV (PWH) experience an increased vulnerability to premature aging and inflammation-associated comorbidities, even when HIV replication is suppressed by antiretroviral therapy (ART). However, the factors that contribute to or are associated with this vulnerability remain uncertain. In the general population, alterations in the glycomes of circulating IgGs trigger inflammation and precede the onset of aging-associated diseases. Here, we investigate the IgG glycomes of cross-sectional and longitudinal samples from 1,216 women and men, both living with virally suppressed HIV and those without HIV. Our glycan-based machine learning models indicate that living with chronic HIV significantly accelerates the accumulation of pro-aging-associated glycomic alterations. Consistently, PWH exhibit heightened expression of senescence-associated glycan-degrading enzymes compared to their controls. These glycomic alterations correlate with elevated markers of inflammatory aging and the severity of comorbidities, potentially preceding the development of such comorbidities. Mechanistically, HIV-specific antibodies glycoengineered with these alterations exhibit reduced anti-HIV IgG-mediated innate immune functions. These findings hold significant potential for the development of glycomic-based biomarkers and tools to identify and prevent premature aging and comorbidities in people living with chronic viral infections.

Association of PTSD With Longitudinal COVID-19 Burden in a Mixed-Serostatus Cohort of Men and Women: Weathering the Storm.

OBJECTIVES: This study of people with HIV (PWH) and those without HIV conducted during the COVID-19 pandemic in the United States in 2020 examines the impact of posttraumatic stress disorder (PTSD) on COVID-19 burden, defined as pandemic-related disruptions. METHODS: Data consisted of survey responses on PTSD among participants (N = 2434) enrolled in the Multicenter AIDS Cohort Study (MACS) and the Women's Interagency HIV (WIHS) cohorts. Unadjusted and adjusted regression models were used to examine the association of PTSD with COVID-19 burden (overall and domain-specific burdens). Quasi-Poisson regression models were used to assess associations with the COVID-19 burden score and 2 domain-specific burdens: (1) changes in resources and (2) interruptions in health care. Analyses was adjusted for age, race/ethnicity, HIV serostatus, current smoking status, number of comorbidities, education, and study regions. RESULTS: Study participants were a median age of 58 (interquartile range, 52-65) years. In both bivariate and multivariable models, PTSD severity was associated with greater overall COVID-19 burden. PTSD severity was associated with the number of resource changes and number of interruptions in medical care. These findings were also consistent across cohorts (MACS/WIHS) and across HIV serostatus, suggesting a greater risk for COVID-19 burden with greater PTSD severity, which remained significant after controlling for covariates. CONCLUSIONS: This study builds on emerging literature demonstrating the impact of mental health on the burden and disruption associated with the COVID-19 pandemic, providing context specific to PWH. The ongoing pandemic requires structural and social interventions to decrease disruption to resources and health resource needs among these vulnerable populations.

Degree of Polypharmacy and Cognitive Function in Older Women with HIV.

The number of people with HIV (PWH) experiencing age-associated comorbidities including those treated with medications and cognitive impairment is increasing. We examined associations between polypharmacy and cognition in older women with HIV (WWH) given their vulnerability to this comorbidity. Cross-sectional analysis capitalizing on Women's Interagency HIV Study data collected between 2014 and 2017. WWH meeting the following criteria were analyzed: age ≥50 years; availability of self-reported non-antiretroviral therapy (ART) medications data; and neuropsychological data. The number of non-ART medications used regularly in the prior 6 months was summed. Polypharmacy was categorized as none/low (0-4), moderate (5-9), or severe (≥10). Multivariable linear regression analyses examined polypharmacy-cognition (T-score) associations in the total sample and among virally suppressed (VS; < 20 copies/mL)-WWH after covariate adjustment for enrollment site, income, depressive symptoms, substance use (smoking, heavy alcohol, marijuana, crack, cocaine, and/or heroin), the Veterans Aging Cohort Study index (indicators of HIV disease and organ system function, hepatitis C virus serostatus), ART use, nadir CD4 count, and specific ART drugs (efavirenz, integrase inhibitors). We included 637 women (median age = 55 years; 72% Black). Ninety-four percent reported ART use in the past 6 months and 75% had HIV RNA <20 copies/mL. Comorbidity prevalence was high (61% hypertension; 26% diabetes). Moderate and severe polypharmacy in WWH were 34% and 24%. In WWH, severe polypharmacy was associated with poorer executive function (p = .007) and processing speed (p = .01). The same pattern of findings remained among VS-WWH. Moderate polypharmacy was not associated with cognition. Moderate and severe polypharmacy were common and associated with poorer executive function and processing speed in WWH. Severe polypharmacy may be a major contributor to the persistence of domain-specific cognitive complications in older WWH above and beyond the conditions that these medications are used to treat.

Socioeconomic, Psychosocial, and Clinical Factors Associated With Employment in Women With HIV in the United States: A Correlational Study.

ABSTRACT: Employment is a social determinant of health, and women living with HIV (WLWH) are often underemployed. This correlational study examined the socioeconomic, psychosocial, and clinical factors associated with employment among WLWH (n = 1,357) and women at risk for HIV (n = 560). Descriptive and inferential statistics were used to evaluate factors associated with employment status. Employment was associated (p ≤ .05) with better socioeconomic status and quality of life (QOL), less tobacco and substance use, and better physical, psychological, and cognitive health. Among WLWH, employment was associated (p ≤ .05) with improved adherence to HIV care visits and HIV RNA viral suppression. Using multivariable regression modeling, differences were found between WLWH and women at risk for HIV. Among WLWH, household income, QOL, education, and time providing childcare remained associated with employment in adjusted multivariable analyses (R2 = .272, p < .001). A better understanding of the psychosocial and structural factors affecting employment is needed to reduce occupational disparities among WLWH.

Relationship between food insecurity and smoking status among women living with and at risk for HIV in the USA: a cohort study.

OBJECTIVES: People living with HIV (PLHIV) in the USA, particularly women, have a higher prevalence of food insecurity than the general population. Cigarette smoking among PLHIV is common (42%), and PLHIV are 6-13 times more likely to die from lung cancer than AIDS-related causes. This study sought to investigate the associations between food security status and smoking status and severity among a cohort of predominantly low-income women of colour living with and without HIV in the USA. DESIGN: Women enrolled in an ongoing longitudinal cohort study from 2013 to 2015. SETTING: Nine participating sites across the USA. PARTICIPANTS: 2553 participants enrolled in the Food Insecurity Sub-Study of the Women's Interagency HIV Study, a multisite cohort study of US women living with HIV and demographically similar HIV-seronegative women. OUTCOMES: Current cigarette smoking status and intensity were self-reported. We used cross-sectional and longitudinal logistic and Tobit regressions to assess associations of food security status and changes in food security status with smoking status and intensity. RESULTS: The median age was 48. Most respondents were African-American/black (72%) and living with HIV (71%). Over half had annual incomes ≤US$12 000 (52%). Food insecurity (44%) and cigarette smoking (42%) were prevalent. In analyses adjusting for common sociodemographic characteristics, all categories of food insecurity were associated with greater odds of current smoking compared with food-secure women. Changes in food insecurity were also associated with increased odds of smoking. Any food insecurity was associated with higher smoking intensity. CONCLUSIONS: Food insecurity over time was associated with smoking in this cohort of predominantly low-income women of colour living with or at risk of HIV. Integrating alleviation of food insecurity into smoking cessation programmes may be an effective method to reduce the smoking prevalence and disproportionate lung cancer mortality rate particularly among PLHIV.

Characteristics of the MACS/WIHS Combined Cohort Study: Opportunities for Research on Aging With HIV in the Longest US Observational Study of HIV.

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.

Food Insecurity and T-cell Dysregulation in Women Living With Human Immunodeficiency Virus on Antiretroviral Therapy.

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 P < .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.

Food insecurity and neurocognitive function among women living with or at risk for HIV in the United States.

BACKGROUND: Neurocognitive impairment (NCI) persists among women living with HIV. Food insecurity is also common among women and may be an important modifiable contributor of NCI. OBJECTIVE: The goal of this study was to determine the association of food insecurity with neurocognitive function among women living with or without HIV. METHODS: From 2013 to 2015, we analyzed data from a cross-sectional sample from the Women's Interagency HIV Study (WIHS). Measures included food insecurity and a comprehensive neuropsychological test battery assessing executive function, processing speed, attention/working memory, learning, memory, fluency, and motor function. We conducted multivariable linear regressions to examine associations between food insecurity and domain-specific neurocognitive performance, adjusting for relevant sociodemographic, behavioral, and clinical factors. RESULTS: Participants (n = 1,324) were predominantly HIV seropositive (68%), Black/African-American (68%) or Hispanic (16%), and low income (48% reported <$12,000/y), with a median age of 49.6 y (IQR = 43.1, 55.5). Approximately one-third (36%, n = 479) were food insecure. Food insecurity was associated with poorer executive function (b = -1.45, SE = 0.58, P ≤ 0.01) and processing speed (b = -1.30, SE = 0.59, P ≤ 0.05). HIV serostatus modified the association between food insecurity and learning, memory, and motor function (P values <0.05). Food insecurity was positively associated with learning among women living with HIV (b = 1.58, SE = 0.77, P ≤ 0.05) and negatively associated with motor function among HIV-negative women (b = -3.57, SE = 1.08, P ≤ 0.001). CONCLUSIONS: Food insecurity was associated with domain-specific neurocognitive function in women, and HIV serostatus modified associations. Food security may be an important point of intervention for ethnically diverse women with low socioeconomic status. Longitudinal studies are warranted to determine potential pathways by which food insecurity is associated with neurocognitive function among women living with or at risk for HIV.

Syndemic burden and systemic inflammation, HIV health status, and blood pressure among women with unsuppressed HIV viral loads among women living with HIV.

INTRODUCTION: Smoking, low education, obesity, and depressive symptoms are all associated with HIV health status, increased blood pressure, and inflammation, and constitute a syndemic burden that may contribute to poor health outcomes. The current study examined syndemic burden and health outcomes among women living with HIV. METHODS: Women were participants enrolled in the Women's Interagency HIV Study. Outcomes included blood pressure, HIV health status (HIV-1 RNA viral load and CD4 T-cell counts), and IL-6. Syndemic burden was defined as a count variable of low education, obesity, cigarette use, and depressive symptoms. RESULTS: Women (N = 131) were an average of 60.54 years of age (SD = 8.86), and 49% were non-Hispanic Black. In multivariable analyses, syndemic burden was not significantly associated with SBP (P = 0.342) or DBP (P = 0.763), IL-6 (P = 0.168), or CD4 cell count (P = 0.846). However, syndemic burden was associated with increased viral load (age adjusted ß = 0.35, P < 0.001). Comparing women with high versus low syndemic burden, also controlling for women's age, women with high syndemic burden had higher DBP and HIV viral load. DISCUSSION: Syndemic burden appeared to play an important role in HIV health status and could potentially increase the risk of HIV transmission. High syndemic burden, defined as at least two syndemic conditions, had the greatest effects of HIV viral load and DBP. Targeted interventions to address syndemic burden may help improve health outcomes in women living with HIV as well as reduce the risk of hypertension and HIV transmission.

Oral health-related quality of life and unmet dental needs among women living with HIV.

BACKGROUND: Oral health-related quality of life (OHRQoL) is a multidimensional, perception-based measure of how oral health affects social and physical functioning and self-image. OHRQoL is important for assessing women living with HIV (WLWH) who may have unmet dental needs and experience disparities that impact dental care accessibility. METHODS: In 2016, the authors conducted an assessment of OHRQoL among a national sample of 1,526 WLWH in the Women's Interagency HIV Study using the Oral Health Impact Profile instrument, which assesses the frequency of 14 oral health impact items. OHRQoL was measured using multivariable linear regression with a negative binomial distribution to assess the association between report of a recent unmet dental need and OHRQoL. RESULTS: "Fair or poor" oral health condition was reported by 37.8% (n = 576) of WLWH. Multivariable linear regression showed that unmet dental needs had the strongest positive association with poor OHRQoL (difference in Oral Health Impact Profile mean, 2.675; P < .001) compared with not having unmet needs. The frequency of dental care utilization was not associated with higher OHRQoL. Older age, fair or poor dental condition, smoking, symptoms of anxiety and loneliness, and poor OHRQoL were also associated with worse OHRQoL. CONCLUSION: Self-perceived impact of oral health on social and physical function and self-image, as measured by OHRQoL, may be an easily assessable but underrecognized aspect of OHRQoL, particularly among women aging with HIV. PRACTICAL IMPLICATIONS: Dentists should implement OHRQoL assessments in their management of the care of patients with HIV to identify those who do have significant oral health impacts.

Food Insecurity Is Associated With Lower Levels of Antiretroviral Drug Concentrations in Hair Among a Cohort of Women Living With Human Immunodeficiency Virus in the United States.

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.

Probiotics and prebiotics in intestinal health and disease: from biology to the clinic.

Probiotics and prebiotics are microbiota-management tools for improving host health. They target gastrointestinal effects via the gut, although direct application to other sites such as the oral cavity, vaginal tract and skin is being explored. Here, we describe gut-derived effects in humans. In the past decade, research on the gut microbiome has rapidly accumulated and has been accompanied by increased interest in probiotics and prebiotics as a means to modulate the gut microbiota. Given the importance of these approaches for public health, it is timely to reiterate factual and supporting information on their clinical application and use. In this Review, we discuss scientific evidence on probiotics and prebiotics, including mechanistic insights into health effects. Strains of Lactobacillus, Bifidobacterium and Saccharomyces have a long history of safe and effective use as probiotics, but Roseburia spp., Akkermansia spp., Propionibacterium spp. and Faecalibacterium spp. show promise for the future. For prebiotics, glucans and fructans are well proven, and evidence is building on the prebiotic effects of other substances (for example, oligomers of mannose, glucose, xylose, pectin, starches, human milk and polyphenols).

Food Insecurity Is Associated With Inflammation Among Women Living With HIV.

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.

Room for Improvement: The HIV-Diabetes Care Continuum Over 15 Years in the Women's Interagency HIV Study.

BACKGROUND: Gains in life expectancy through optimal control of HIV infection with antiretroviral therapy (ART) may be threatened if other comorbidities, such as diabetes, are not optimally managed. METHODS: We analyzed cross-sectional data of the Women's Interagency HIV Study (WIHS) from 2001, 2006, and 2015. We estimated the proportions of HIV-positive and HIV-negative women with diabetes who were engaged in care and achieved treatment goals (hemoglobin A1c [A1c] <7.0%, blood pressure [BP] <140/90 mmHg, low-density lipoprotein [LDL] cholesterol <100 mg/dL, not smoking) and viral suppression. Repeated-measures models were used to estimate the adjusted prevalence of achieving each diabetes treatment goal at each time point, by HIV status. RESULTS: We included 486 HIV-positive and 258 HIV-negative women with diabetes. In 2001, 91.8% visited a health care provider, 60.7% achieved the A1c target, 70.5% achieved the BP target, 38.5% achieved the LDL cholesterol target, 49.2% were nonsmokers, 23.3% achieved combined ABC targets (A1c, BP, and cholesterol), and 10.9% met combined ABC targets and did not smoke. There were no differences by HIV status, and patterns were similar in 2006 and 2015. Among HIV-positive women, viral suppression increased from 41% in 2001 to 87% in 2015 compared with 8% and 13% achieving the ABC goals and not smoking. Viral suppression was not associated with achievement of diabetes care goals. CONCLUSIONS: Successful management of HIV is outpacing that of diabetes. Future studies are needed to identify factors associated with gaps in the HIV-diabetes care continuum and design interventions to better integrate effective diabetes management into HIV care.

Evidence-based HMO care for prostate specific antigen testing.

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.

The Impact of Substance Use on Adherence to Antiretroviral Therapy Among HIV-Infected Women in the United States.

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.

Higher Body Mass Index Is Associated With Greater Proportions of Effector CD8+ T Cells Expressing CD57 in Women Living With HIV.

BACKGROUND: A low proportion of CD28CD8 T cells that express CD57 is associated with increased mortality in HIV infection. The effect of increasing body mass index (BMI) changes in the proportion of CD57CD28CD8 T cells among HIV-infected individuals on antiretroviral therapy is unknown. SETTING: In a US cohort of HIV-infected women, we evaluated associations of BMI and waist circumference with 3 distinct CD8 T cell phenotypes: % CD28CD57CD8 T cells, % CD57 of CD28CD8 T cells, and % CD28 of all CD8 T cells. METHODS: Multivariable linear regression analysis was used to estimate beta coefficients for each of 3 T-cell phenotypes. Covariates included HIV parameters (current and nadir CD4, current viral load), demographics (age, race, income, and study site), and lifestyle (tobacco and alcohol use) factors. RESULTS: Of 225 participants, the median age was 46 years and 50% were obese (BMI >30 m/kg). Greater BMI and waist circumference were both associated with higher % CD28CD57CD8 T cells and % CD57 of all CD28CD8 T cells in multivariable analysis, including adjustment for HIV viral load (all P < 0.05). The association between greater BMI and the overall proportion of CD28 CD8 cells in fully adjusted models (0.078, 95% confidence interval: -0.053 to 0.209) was not significant. CONCLUSIONS: In this analysis, greater BMI and waist circumference are associated with greater expression of CD57 on CD28CD8 T cells and a greater proportion of CD57CD28 CD8 T cells. These findings may indicate that increasing BMI is immunologically protective in HIV-infected women. Future research is needed to understand the prognostic importance of these associations on clinical outcomes.

Variability in orthopedic surgeon treatment preferences for nondisplaced scaphoid fractures: A cross-sectional survey.

PURPOSE: The absence of a best practice treatment standard contributes to clinical variation in medicine. Often in the absence of evidence, a standard of care is developed and treatment protocols are implemented. The purpose of this study was to examine whether the standard of care for the treatment of nondisplaced scaphoid fractures is uniform among orthopedic surgeons. METHODS: A survey of orthopedic surgeons actively practicing in the US or abroad was conducted to elicit preferred treatment strategies for nondisplaced scaphoid fractures. The surgeons were recruited at orthopedic conferences, clinical visits, and via email. The survey included demographic questions along with a short clinical vignette. The option for fracture management included surgical versus nonsurgical treatment. For those who chose nonsurgical treatment, type/duration of immobilization was recorded. Cost analysis was performed to estimate direct and indirect costs of various treatment options. RESULTS: A total of 494 orthopedic surgeons completed the survey. The preference for surgical treatment was preferred in 13% of respondents. Hand/upper extremity specialists were significantly more likely to operate compared with generalists (p = 0.0002). Surgeons younger than forty-five were nearly twice as likely to choose surgery (p = 0.01). There was no clear consensus on duration of immobilization as 30% of surgeons chose 6 weeks, 33% selected 8 weeks, and 27% opted for 12 weeks. Total cost of surgery was 49% greater than that of nonoperative treatment. With each additional week of immobilization for nonoperative treatment, the total costs of surgical treatment near that of nonoperative treatment. CONCLUSION: There exist clear trends in how specific demographic groups choose to treat the nondisplaced scaphoid fracture. Whether these trends are the result of generational gaps or additional subspecialty training remains difficult to determine, but there is need to pursue a more consistent approach that benefits the patients and the health care system as a whole.

Lack of Agreement on Distal Radius Fracture Treatment.

INTRODUCTION: Variation in clinical practice resulting from the absence of evidence-based treatment protocols has negative implications on both the cost and the quality of medical care. The objective of this study was to assess whether a standard of care for the treatment of extra-articular nondisplaced distal radius fracture has developed despite the lack of a conclusive recommendation from the American Academy of Orthopaedic Surgeons. METHODS: A case-vignette survey was conducted. Treatment type and duration of casting selections were analyzed. The cost implications of responses were assessed. Participants were practicing orthopedists primarily in the mid-Atlantic region of the United States. Orthopedists (n = 494) were recruited via E-mail and at the American Academy of Orthopaedic Surgeons Annual Meeting held in Chicago in March 2013. Inclusion criteria required that participants be graduates of an accredited medical school and be practicing orthopedists at the time of survey distribution. The main outcome measure was surgical or nonsurgical intervention. RESULTS: Nonsurgical treatment was selected by 60% of respondents, with surgery preferred by 37%. Duration of casting responses varied from 2 to 12 weeks. Among nonsurgical responses, 69% indicated 6 weeks as their preferred duration of casting (95% confidence interval, 64.9-73.1%). Surgery imposes a 76% greater total cost to society than nonsurgical treatments. CONCLUSIONS: Our findings suggest the absence of a consensus strategy for the treatment of extra-articular nondisplaced distal radius fractures. Implications of variance in treatment on cost and quality support the need for established, evidence-based guidelines or further clinical trials to assist in the management of this common fracture.

Patient Preferences for Receiving Reports of Test Results.

INTRODUCTION: The general public's preferences for modes of communication (other than in-person communication) for medical test results were investigated. We hypothesized that patients would prefer a variety of methods to receive common tests results (blood cholesterol and colonoscopy) compared with genetics test results. METHODS: This study was a cross-sectional survey. RESULTS: A total of 409 participants responded to the survey. Among these participants, ≥50% reported that they were comfortable receiving results for a blood cholesterol test or colonoscopy via 4 of the 7 non-in-person communication methods (password-protected website, personal voicemail, personal E-mail, and letter were preferred over home voicemail, fax, and mobile phone text message). In comparison, >50% of participants were comfortable with only 1 non-in-person communication method for non-HIV sexually transmitted infections (STIs) and none for genetic tests. Patients were least comfortable receiving any information via fax, regardless of test type. There were statistical differences among comfort levels for blood cholesterol and colonoscopy tests and both STIs and genetic testing for personal voicemail, personal E-mail, mobile phone text message, and password-protected website, but there were no differences between STIs and genetic testing. No correlation was found between "familiarity" with test and "comfort" of receiving information about specific test. CONCLUSIONS: Participants demonstrated preferences in how they received test results by non-in-person communication methods, preferring personal E-mail and password-protected websites, but did not prefer fax. Importantly, participants also demonstrated that preference was dependent on test type.
