HIV Transgenic Rats Demonstrate Impaired Sensorimotor Gating But Are Insensitive to Cannabinoid (Δ9-Tetrahydrocannabinol)-Induced Deficits.

BACKGROUND: HIV-associated neurocognitive disorder (HAND) is commonly observed in persons living with HIV (PWH) and is characterized by cognitive deficits implicating disruptions of fronto-striatal neurocircuitry. Such circuitry is also susceptible to alteration by cannabis and other drugs of abuse. PWH use cannabis at much higher rates than the general population, thus prioritizing the characterization of any interactions between HIV and cannabinoids on cognitively relevant systems. Prepulse inhibition (PPI) of the startle response, the process by which the motor response to a startling stimulus is attenuated by perception of a preceding non-startling stimulus, is an operational assay of fronto-striatal circuit integrity that is translatable across species. PPI is reduced in PWH. The HIV transgenic (HIVtg) rat model of HIV infection mimics numerous aspects of HAND, although to date the PPI deficit observed in PWH has yet to be fully recreated in animals. METHODS: PPI was measured in male and female HIVtg rats and wild-type controls following acute, nonconcurrent treatment with the primary constituents of cannabis: Δ 9-tetrahydrocannabinol (THC; 1 and 3 mg/kg, s.c.) and cannabidiol (1, 10, and 30 mg/kg, i.p.). RESULTS: HIVtg rats exhibited a significant PPI deficit relative to wild-type controls. THC reduced PPI in controls but not HIVtg rats. Cannabidiol exerted only minor, genotype-independent effects on PPI. CONCLUSIONS: HIVtg rats exhibit a relative insensitivity to the deleterious effects of THC on the fronto-striatal function reflected by PPI, which may partially explain the higher rates of cannabis use among PWH.

Nature-Based Therapies for Sleep Disorders in People Living with Human Immunodeficiency Virus.

Following diagnosis of human immunodeficiency virus (HIV), getting adequate sleep may be the farthest thing from the mind of patients or providers. Even further from mind are the potential benefits on both sleep and HIV from nature-based therapy. In developing and developed countries, access to high-quality natural spaces has the potential to support physical and mental health. This article provides a review of sleep disorders, conventional and nature-based therapies, and the potential of nature-based therapy to support the health of people living with HIV through increased restorative sleep and immune function.

Resistance training with blood flow restriction: Impact on the muscle strength and body composition in people living with HIV/AIDS.

The aim of the study was to compare the impact of 12-week resistance training with blood flow restriction (GRTBFR) versus, traditional resistance training (GTRT) and non-training on the muscle strength and body composition HIV/AIDS participants. Muscle strength was tested at baseline, and on the 6th, 21st and 36th training sessions, using maximal repetition test. Pre- and post-intervention body composition changes were measured by dual-energy X-ray absorptiometry. Resistance training was undertaken three times a week comprising bilateral elbow extension and flexion exercises, unilateral flexion and bilateral knee extension. Changes in strength and body composition (pre- and post-intervention) between groups were evaluated by mixed models of repeated measures, and by paired and unpaired comparisons, considering the Effect Size. All groups were similar at baseline for muscle strength and body composition. Post-intervention, the training groups showed similar, statistically significant increases in muscle strength (GRTBFR=25.7-57.4%; GTRT=24.5-52.3%) and skeletal muscle tissue (GRTBFR=8.4%; GTRT=8.3%). There was also a significant change in body fat (p=0.023-0.043), with significant effect sizes for strength and skeletal muscle tissue (0.41-2.27), respectively. These results suggest that both resistance training interventions promoted muscle hypertrophy, body fat reduction and positive impact on muscle strength in people living with HIV/AIDS. Resistance training with blood flow restriction proved to be an effective alternative to include patients with marked physical weakness, unable to engage in regular strength training programme.ClinicalTrials.gov identifier: NCT02783417.

HIV-related disability and rehabilitation: perception of health care workers.

Background: Health care workers play an integral role in the rehabilitation and care of people living with HIV who face multiple impairments and often disabilities. The aim of the article was to understand the perceptions and attitudes of health care workers towards caring for people living with HIV, and experiencing disability. Methods: Fifteen health care workers offering care to people living with HIV were interviewed using a semi-structured guide. These health care workers included doctors, a social worker, a pharmacist, a dietician, an occupational therapist, a physiotherapist, and nurses and HIV couPnsellors who were employed at a public health care facility in KwaZulu-Natal. Data from the interviews were transcribed and analysed using conventional content analysis. Results: Four themes emerged from semi-structured interviews with the health care workers: a holistic disability framework, a multidisciplinary team dynamic, organisational barriers and recommendations by health care workers. Conclusion: Health care workers perceived a shift from a biomedical perspective of disability to a bio-psychosocial interpretation that is influenced by contextual and environmental barriers imposed by communities on people living with HIV. Barriers included stigmatisation that leads to attitudinal barriers and social exclusion of people living with HIV and experiencing disabilities within communities. Lack of resources, including of equipment, and a shortage of health care staff also posed barriers to the care offered to people living with HIV and experiencing disabilities. Participants agreed that improved communication in the multidisciplinary health care team, as well as continuing education and training, would enable health care workers to offer improved, integrated care to people living with HIV who experience disabilities.

Nutritional Intervention Reduces Dyslipidemia, Fasting Glucose and Blood Pressure in People Living with HIV/AIDS in Antiretroviral Therapy: A Randomized Clinical Trial Comparing Two Nutritional Interventions.

Antiretroviral therapy (ART) increases the risk of cardiometabolic diseases in people living with HIV/AIDS (PLWHA). However, there is a lack of evidence regarding the effectiveness of a nutritional intervention on several cardiometabolic parameters in this population. Therefore, this study aimed to evaluate the effectiveness of two nutritional interventions on several cardiometabolic parameters in PLWHA treated with ART. A parallel randomized clinical trial was performed with PLWHA treated with ART. The participants (n = 88) were divided into two intervention groups: (1) nutritional counseling (n = 44) and (2) individualized dietary prescription (n = 44). The follow-up period was 30 weeks. A reduction in low-density lipoprotein (LDL) was the primary outcome. Secondary outcome variables were reductions in total cholesterol (TC), triglycerides (TG), fasting plasma glucose (FPG), systolic and diastolic blood pressures (SBP and DBP, respectively), waist circumference (WC), body mass index (BMI), and increases in high-density lipoproteins (HDL). A multiple linear regression was used to analyze the effectiveness of the interventions, adjusted for sociodemographic, lifestyle, and clinical characteristics. Sixty-two PLWHA completed the trial (nutritional counseling, n = 32; individualized dietary prescription, n = 30). At follow-up, we observed in the nutritional counseling group significant reductions in SBP (p = 0.036) and DBP (p = 0.001). Significant reductions in FPG (p = 0.008) and DBP (p = 0.023) were found in the individualized dietary prescription group. In the fully adjusted models, significant reductions in LDL, SBP, DBP, and BMI were found in the individualized dietary prescription group. In conclusion, the two investigated nutritional interventions were effective in reducing some cardiometabolic risk factors in PLWHA. However, after adjustments for covariates, the individualized dietary prescription showed significant reductions in the primary outcome and, also, in more cardiometabolic risk factors than the nutritional counseling.

Effectiveness of Medical Nutrition Therapy to Improve Dietary Habits for Promoting Bone Health in People Living with Chronic HIV.

INTRODUCTION: Previous studies have established the risk of bone loss among people living with HIV affected by antiretroviral therapy drug side effects and inadequate nutrient intake. Until recently, there have been limits on using the medical nutrition therapy (MNT) to improve dietary habits for promoting bone health among people living with HIV. This was a randomized controlled trial study aimed to investigate the effectiveness of MNT in improving the bone health in people living with HIV by promoting dietary habits. METHODS: PLHIV at Queen Savang Vadhana Memorial Hospital were randomly grouped (by quota sampling) into the MNT group (intervention group) and the control group. One hundred and thirty PLHIV were recruited to participate in this study by convenient sampling. Sixty-five participants of the MNT group made a total of 6 appointments (for 12 weeks) to meet registered dietitians for receiving MNT to improve dietary habits for improving bone health, while 65 participants in the control group received only routine care at the hospital service center. RESULTS: In general, participants in the MNT group had significant increase in the amounts of calcium, vitamin D, potassium, and phosphorus intakes and length of exercise after the final week compared with before intervention. Also, they had significantly higher amount of nutrient intakes (calcium, vitamin D, potassium, and phosphorus) and length of exercise than the control group after finishing the final week of the experiment. CONCLUSION: In conclusion, MNT is effective for improving food habits and physical activity to promote bone health among people living with HIV.

S-EQUOL: a neuroprotective therapeutic for chronic neurocognitive impairments in pediatric HIV.

Chronic neurocognitive impairments, commonly associated with pediatric human immunodeficiency virus type 1 (PHIV), are a detrimental consequence of early exposure to HIV-1 viral proteins. Strong evidence supports S-Equol (SE) as an efficacious adjunctive neuroprotective and/or neurorestorative therapeutic for neurocognitive impairments in adult ovariectomized female HIV-1 transgenic (Tg) rats. There remains, however, a critical need to assess the therapeutic efficacy of SE when treatment occurs at an earlier age (i.e., resembling a therapeutic for children with PHIV) and across the factor of biological sex. Utilization of a series of signal detection operant tasks revealed prominent, sex-dependent neurocognitive deficits in the HIV-1 Tg rat, characterized by alterations in stimulus-reinforcement learning, the response profile, and temporal processing. Early (i.e., postnatal day 28) initiation of SE treatment precluded the development of chronic neurocognitive impairments in all (i.e., 100%) HIV-1 Tg animals, albeit not for all neurocognitive domains. Most notably, the therapeutic effects of SE are generalized across the factor of biological sex, despite the presence of endogenous hormones. Results support, therefore, the efficacy of SE as a neuroprotective therapeutic for chronic neurocognitive impairments in the post-cART era; an adjunctive therapeutic that demonstrates high efficacy in both males and females. Optimizing treatment conditions by evaluating multiple factors (i.e., age, neurocognitive domains, and biological sex) associated with PHIV and HIV-1 associated neurocognitive disorders (HAND) affords a key opportunity to improve the therapeutic efficacy of SE.

Dietary nitrate improves skeletal muscle microvascular oxygenation in HIV-infected patients receiving highly active antiretroviral therapy: a randomised, double-blind, cross-over, placebo-controlled study.

HIV-1 proteins and highly active antiretroviral therapy (HAART) have been associated with microvascular endothelial dysfunction. Although nitrate-rich beetroot juice (NR-BJ) consumption has been shown to improve endothelial function in clinical population, its effects in HIV-infected patients has not been addressed. We investigated the effect of a single dose of NR-BJ on muscle oxygen saturation parameters in response to a handgrip exercise in HIV-infected patients. Fifteen HIV-infected patients received NR-BJ or nitrate-depleted beetroot juice (ND-BJ) in a double-blind cross-over design. Near-IR spectroscopy was utilised to assess muscle oxygen saturation parameters during rhythmic handgrip exercise after NR-BJ or ND-BJ supplementation. A significant faster muscle oxygen desaturation rate during exercise (-7·97 (sd 5·00) v. -5·45 (3·94) %/s, P = 0·005) and muscle oxygen resaturation rate during exercise recovery (0·43 (0·24) v. 0·28 (0·24) %/s, P = 0·030) after NR-BJ ingestion was found. However, no significant difference in exercise time until fatigue was observed. Salivary nitrite and urinary nitrate concentration were analysed after NR-BJ or ND-BJ. A significant increase in salivary nitrite and urinary nitrate in NR-BJ was observed compared with ND-BJ (P < 0·05). Our findings suggest that NR-BJ consumption may acutely improve muscle oxygen saturation during exercise and exercise recovery in HIV-infected patients undergoing HAART and who are expected to present microvascular damage. Thus, future studies investigating the chronic effects of NR-BJ are warranted to delineate a better nutritional strategy based on nitrate-rich foods.

1-O-Acetylgeopyxin A, a derivative of a fungal metabolite, blocks tetrodotoxin-sensitive voltage-gated sodium, calcium channels and neuronal excitability which correlates with inhibition of neuropathic pain.

Chronic pain can be the result of an underlying disease or condition, medical treatment, inflammation, or injury. The number of persons experiencing this type of pain is substantial, affecting upwards of 50 million adults in the United States. Pharmacotherapy of most of the severe chronic pain patients includes drugs such as gabapentinoids, re-uptake blockers and opioids. Unfortunately, gabapentinoids are not effective in up to two-thirds of this population and although opioids can be initially effective, their long-term use is associated with multiple side effects. Therefore, there is a great need to develop novel non-opioid alternative therapies to relieve chronic pain. For this purpose, we screened a small library of natural products and their derivatives in the search for pharmacological inhibitors of voltage-gated calcium and sodium channels, which are outstanding molecular targets due to their important roles in nociceptive pathways. We discovered that the acetylated derivative of the ent-kaurane diterpenoid, geopyxin A, 1-O-acetylgeopyxin A, blocks voltage-gated calcium and tetrodotoxin-sensitive voltage-gated sodium channels but not tetrodotoxin-resistant sodium channels in dorsal root ganglion (DRG) neurons. Consistent with inhibition of voltage-gated sodium and calcium channels, 1-O-acetylgeopyxin A reduced reduce action potential firing frequency and increased firing threshold (rheobase) in DRG neurons. Finally, we identified the potential of 1-O-acetylgeopyxin A to reverse mechanical allodynia in a preclinical rat model of HIV-induced sensory neuropathy. Dual targeting of both sodium and calcium channels may permit block of nociceptor excitability and of release of pro-nociceptive transmitters. Future studies will harness the core structure of geopyxins for the generation of antinociceptive drugs.

Reorienting health systems to care for people with HIV beyond viral suppression.

The effectiveness of antiretroviral therapy and its increasing availability globally means that millions of people living with HIV now have a much longer life expectancy. However, people living with HIV have disproportionately high incidence of major comorbidities and reduced health-related quality of life. Health systems must respond to this situation by pioneering care and service delivery models that promote wellness rather than mere survival. In this Series paper, we review evidence about the emerging challenges of the care of people with HIV beyond viral suppression and identify four priority areas for action: integrating HIV services and non-HIV services, reducing HIV-related discrimination in health-care settings, identifying indicators to monitor health systems' progress toward new goals, and catalysing new forms of civil society engagement in the more broadly focused HIV response that is now needed worldwide. Furthermore, in the context of an increasing burden of chronic diseases, we must consider the shift that is underway in the HIV field in relation to burgeoning policy and programmatic efforts to promote healthy ageing.

Lipid based nutrient supplements during pregnancy may improve foetal growth in HIV infected women - A cohort study.

OBJECTIVES: Both maternal HIV infection and antiretroviral therapy are associated with adverse birth outcomes. The role of antenatal nutrient supplements with regard to adverse birth outcomes in HIV infected women exposed to antiretroviral therapy is not well known. We assessed the association between HIV and birth outcomes and explored whether antenatal lipid-based nutrient supplements (LNS) modulated this association. METHODS: We analysed a nested cohort of pregnant Malawian women who received daily LNS, multiple micronutrients (MMN) or iron and folic acid (IFA). Birth weight, length-for-age z-score (LAZ) and weight-for-age z-score (WAZ) were analysed as continuous outcomes and proportion of stunting and small-for-gestational age (SGA) as dichotomous outcomes. RESULTS: 134 HIV infected (46 LNS, 39 MMN, 49 IFA) and 833 HIV uninfected (271 LNS, 287 MMN, 275 IFA) women were included. Maternal HIV infection was associated with a lower mean birth weight (-129g (-209, -48), P = 0.002); LAZ (-0.34 (-0.54, -0.13), P = 0.002) and WAZ (-0.21 (-0.40, -0.02), P = 0.041) and a higher risk of stunting (RR (95% confidence interval), 1.87 (1.24, 2.83), P = 0.003) and SGA (1.66 (1.21, 2.26), P = 0.001) in the newborn. If the women received LNS, HIV was not associated with LAZ (mean difference (95%); -0.02 (-0.35, 0.31), P = 0.918) or newborn stunting (RR (95% CI), 0.84 (0.34, 2.03), P = 0.691). However HIV tended to be associated with LAZ if the women received MMN (-0.42 (-0.80, -0.03), P = 0.053); and was significantly associated with LAZ if the women received IFA (-0.52 (-0.89, -0.14), P = 0.021) and with newborn stunting if they received MMN (2.40 (1.15, 4.98), P = 0.029) or IFA (2.40 (1.26, 4.59), P = 0.024). CONCLUSIONS: Further research to investigate the impact of LNS on various aspects of foetal growth in HIV infected women is warranted.

Glucocorticoid-immune response to acute stress in women and men living with HIV.

Despite high risk for serious non-AIDS events (SNAEs) and accelerated age-related increases in inflammatory markers relative to HIV+ men, HIV+ women have been understudied, particularly in terms of stress impacts on immune parameters. The purpose of this study was to examine sex differences in glucocorticoid-immune stress response in mid-life HIV+ individuals, as poor glucocorticoid control of stress-induced inflammation may contribute to health risk in HIV+ women. Male and female participants completed a threat of shock laboratory stressor. Serum cortisol and cytokines [interleukin (IL)-6, IL-8, IL-10, IL-1ß, C-reactive protein (CRP), tumor necrosis factor (TNF)-α, interferon (IFN)-γ] were assessed at six timepoints prior to and in response to the stressor. Participants included 8 HIV- controls (n = 5 female) and 9 HIV+ (n = 5 female) who were virally suppressed. Repeated measures mixed models revealed a significant sex by HIV status by time interaction for IL-10, IL-1ß, TNF-α, and cortisol. IL-10 response, an anti-inflammatory cytokine, was larger in males than females, regardless of HIV status. TNF-α response was blunted in HIV+ individuals compared with HIV-, and specifically in HIV+ women, IL-1ß and cortisol response were blunted. Individuals living with HIV may have impaired coordination between the immune system and hypothalamic pituitary adrenal (HPA) axis. HIV+ women in particular exhibited dysregulated IL-1ß and cortisol response to acute stress. Future work should focus on relationships among proinflammatory cytokines, stress, and SNAEs in HIV, with attention to sex as a biological variable.

Effect of baseline micronutrient and inflammation status on CD4 recovery post-cART initiation in the multinational PEARLS trial.

BACKGROUND & AIMS: Nutritional deficiency and inflammation may impact CD4+ T cell recovery during combination antiretroviral therapy (cART), particularly in resource-limited settings where malnutrition is prevalent. The aim of this study was to investigate the relationship of micronutrient and inflammation biomarkers to CD4 recovery after cART initiation. METHODS: We conducted a secondary analysis of a random sub-cohort sample (n = 270) from a multinational randomized trial of cART regimen efficacy among 1571 cART-naïve adults. We measured pre-cART serum levels of micronutrients (Vitamin A, B6, B12, D, total carotenoids, selenium, and iron) and inflammation (C-reactive protein, soluble CD14 (sCD14), IFNγ, TNFα, Interleukin-6, and C-X-C motif chemokine 10 (CXCL10/IP10), EndoCab (IgM)) biomarkers. Biomarker status (i.e. micronutrient deficiency vs. sufficiency and elevated vs. low inflammation) was defined using established cutoffs or quartiles. Mixed-effects linear regression models were used to determine the association of baseline (pre-cART) concentrations of individual biomarkers with CD4 recovery through 96 weeks post-cART initiation. RESULTS: In models adjusting for time-dependent viral load and baseline CD4 count, age, sex, body mass index, country, treatment regimen, anemia and hypoalbuminemia status, pre-cART vitamin D deficiency was associated with lower CD4 recovery (-14.9 cells/mm3, 95% CI: -27.9, -1.8) compared to sufficiency. In contrast, baseline selenium deficiency (20.8 cells/mm3, 95% CI: 3.3, 38.3), vitamin A deficiency (35.9 cells/mm3, 95% CI: 17.6, 54.3) and high sCD14 (23.4 cells/mm3, 95% CI: 8.9, 37.8) were associated with higher CD4 recovery compared to sufficient/low inflammation status. CONCLUSIONS: In summary, baseline vitamin D deficiency was associated with diminished CD4 recovery after cART initiation; impaired CD4 recovery may contribute to the poor clinical outcomes recently observed in individuals with vitamin D deficiency. Vitamin A, selenium and sCD14 were associated with CD4 recovery but future studies are needed to further explore these relationships.

Revisiting Successful Aging With HIV Through a Revised Biopsychosocial Model: An Update of the Literature.

The concept of successful aging was recognized only recently by HIV researchers because people living with HIV (PLWH) in the early epidemic were not expected to survive. With the introduction of antiretrovirals that block viral replication, PLWH are now aging with HIV. Given the complex nature of HIV within the social, economic, and political climates in which it occurs, a holistic model of successful aging is needed to guide researchers and clinicians. Several overarching models exist, but must be updated for rapidly advancing HIV and aging research agendas. We provide an updated, adapted, and integrated biopsychosocial model of successful aging with HIV based on the principles of Baltes and Baltes (1998) on 8 essential components of successful aging: (a) length of life, (b) biological health, (c) mental health, (d) cognitive efficiency, (e) social competence, (f) productivity, (g) personal control, and (h) life satisfaction. Clinical practice and research implications are highlighted.

Capsaicin 8% Dermal Patch: A Review in Peripheral Neuropathic Pain.

The adhesive capsaicin dermal patch (Qutenza®) delivers a high concentration (8% w/w) of synthetic capsaicin, a highly selective agonist of transient receptor potential vanilloid-1 (TRPV-1), directly to the site of pain. The capsaicin 8% dermal patch is indicated in the EU for the treatment of peripheral neuropathic pain (PNP) in adults, either alone or in combination with other medicinal products for pain. In patients with painful diabetic peripheral neuropathy, a single 30-min application of the capsaicin 8% dermal patch provided 12 weeks of pain relief and improved sleep quality compared with placebo. Repeat treatment with the capsaicin 8% dermal patch plus standard of care over 52 weeks provided sustained pain relief, with no negative neurological effects compared with standard of care alone. The capsaicin 8% dermal patch was non-inferior to oral pregabalin in relieving pain in patients with non-diabetic PNP, with a faster onset of action and greater treatment satisfaction. A single 60-min application of the capsaicin 8% dermal patch provided rapid and sustained pain relief in patients with postherpetic neuralgia. Results in patients with HIV-associated neuropathy were equivocal, with a significant improvement in pain intensity observed in one trial, but not in the other. The capsaicin 8% dermal patch was generally well tolerated; transient application-site reactions were the most common adverse events. In conclusion, the capsaicin 8% dermal patch is a useful addition to the treatment options currently available for patients with PNP.

Effectiveness of macronutrient supplementation on nutritional status and HIV/AIDS progression: A systematic review and meta-analysis.

BACKGROUND & AIMS: Malnutrition is common in Sub-Saharan Africa, weakening the immune function of persons living with HIV infection (PLWH). Being malnourished at the initiation of antiretroviral therapy (ART) leads to higher risk of early mortality and reduced quality of life. Thus, introduction of protein-energy-fortified macronutrient supplements at ART initiation may improve HIV treatment outcomes. This review aimed to evaluate the effectiveness of macronutrient interventions. METHODS: This systematic review and meta-analysis included 15 studies conducted from 2000 to 2015 among Sub-Saharan African adults. RESULTS: Six randomized controlled trials and 4 retrospective cohort studies provided data eligible for a meta-analysis. Supplementation significantly increased the overall standardized mean difference (SMD) between baseline and follow-up data in weight (SMD = 0.382, p < .001), BMI (SMD = 0.799, p < .001); fat-free mass (SMD = 0.154, p = .009); and CD4 count (SMD = 0.428, p < .001). CONCLUSION: Protein-energy-fortified macronutrient supplementation at ART initiation may positively influence nutritional status and immunologic response in PLWH in Sub-Saharan Africa.

Vitamin D supplementation, bone turnover, and inflammation in HIV-infected patients.

OBJECTIVE: To assess whether vitamin D supplementation could be associated with a modification of inflammatory markers and bone turnover in HIV-1-infected patients. PATIENTS AND METHODS: Patients who participated in an initial survey in 2010 and who were followed in the same department were included in a new study in 2012. Between 2010 and 2012, vitamin D supplementation was offered to patients presenting with hypovitaminosis D as per appropriate guidelines. Clinical examinations were performed, and fasting blood samples were taken for inflammation and bone marker evaluations. RESULTS: Of the 263 patients who participated in the 2010 study, 198 were included in the 2012 study. Hypovitaminosis D was observed in 47% (36/77) of participants supplemented as per appropriate guidelines, in 78% (75/97) of transiently or incompletely supplemented participants, and in 71% (17/24) of non-supplemented participants (mainly because vitamin D levels in 2010 were normal). No significant correlation between vitamin D supplementation and the 2-year inflammation outcome (IL-6 and hsCRP) or C-terminal telopeptide levels was observed. However, a decrease in IL6 levels over the 2 years significantly correlated with reaching a normal vitamin D level (OR=0.89 per+1pg/mL IL6 increase, 95% CI=0.81-0.97, P=0.015). CONCLUSIONS: Vitamin D supplementation decreases the risk of hypovitaminosis D but does not decrease the risk of inflammation nor bone turnover, unless normal 25-OH vitamin D levels are reached.

HIV and the menopause: A review.

Effective antiretroviral therapy has resulted in a close to normal life expectancy for people living with HIV. This has led to a shift in the age distribution of women living with HIV in the UK, with one in three attending for HIV care estimated to be aged 45-56 years in 2014. The lack of experience of many HIV physicians in managing menopause, and the perceived complexity of managing menopause in women living with HIV by general practitioners means that many women are unable to access appropriate care and support. This is aggravated by the relative paucity of data on menopause in women living with HIV and conflicting results in this field, for example with regard to age of onset of menopause and symptomatology experienced. Furthermore, women living with HIV have unique considerations such as potential interactions between antiretroviral therapy and menopause hormone therapy (previously called hormone replacement therapy) and other physiological concerns such as a multifactorial propensity towards decreased bone mineral density and potentially increased cardiovascular risk. On the whole, menopause hormone therapy is probably underutilised in this group of women due to perceived concerns around drug-drug interactions, as well as fears shared with women in the general population about menopause hormone therapy. Menopausal women should be given adequate information on symptomatology, lifestyle modification and treatment options including menopause hormone therapy. Furthermore, a holistic approach which considers the increased burden of poor mental health in this population is essential.

"It was pain. That's it. It was pain." Lack of oral health care among otherwise healthy young adults living with HIV in South Africa: A qualitative study.

INTRODUCTION: The purpose of this study is to understand engagement with and availability of dental services among people living with HIV in a low-income community of South Africa. METHODS: In depth qualitative interviewing was used to collect data, which was analyzed using an inductive content analytical approach. The study was conducted in Gugulethu, a township community located outside of Cape Town, South Africa. Local public sector health services provided free of charge are the main source of primary health and dental care for this population. Participants included South African adults (age 18-35) recently diagnosed with HIV who had a CD4 count >350 cells/mm3. RESULTS: Many participants had little to no experience with dental care, did not know which health care providers are appropriate to address oral health concerns, were not aware of available dental services, utilized home remedies to treat oral health problems, harbored many misperceptions of dental care, avoided dental services due to fear, and experienced poverty as a barrier to dental services. CONCLUSIONS: Our findings suggest that integration of oral healthcare into medical care may increase patient knowledge about oral health and access to care. Leveraging the relatively robust HIV infrastructure to address oral disease may also be an effective approach to reaching these participants and those living in resource poor communities generally.
