    Associations of depression and anxiety with substance use and social health among older adults living with HIV

    Life expectancy after HIV infection dramatically increased following the development of antiretroviral therapies (ART) in 1996. As the population of older adults living with HIV increases, concerns have grown about possible disparities in mental health. We evaluated mental health outcomes, specifically depressive symptoms and anxiety, among older adults living with HIV in two large urban cities. We also examined the relationship between mental health outcomes and substance use and social health. We recruited 154 participants from infectious disease clinics in Los Angeles, CA and New Orleans, LA to complete cross-sectional surveys. We assessed prevalence of depressive symptoms (CES-D-10) and anxiety (GAD-7). Bivariate analyses and multivariate linear regressions were run to examine the factors associated with depressive symptoms and anxiety. We found that 44.8% of all participants were at risk for clinical depression, 55.8% reported mild to severe levels of anxiety, and 40.0% met criteria for both. In multivariate analyses, greater depressive symptoms and anxiety were associated with greater perceived HIV-related stigma and smaller social networks. Depressive symptoms were additionally associated with younger age. Substance use was not associated with depressive symptoms or anxiety. Findings suggest older adults living with HIV may be at high risk for depression and anxiety and that the presence of these conditions may also be linked to poorer social health indicators. This highlights the importance of screening for and addressing depression and anxiety among older adults with HIV

    A Fatal Case of Herpes Simplex Encephalitis with Two False-Negative Polymerase Chain Reactions

    An 88-year-old man presented with a 1-month history of altered mental status and seizures. His electrographic and imaging findings were suggestive of herpes simplex encephalitis (HSE), for which he was empirically treated with acyclovir. He underwent two lumbar punctures 3 days apart; both cerebrospinal fluid analyses tested negative for herpes simplex virus (HSV) by polymerase chain reaction (PCR). These negative results and his continued deterioration after 9 days of acyclovir therapy prompted treatment with steroids for possible autoimmune encephalitis. Shortly after the change in management, the patient died from cardiac arrest. At autopsy, his brain showed both gross and microscopic evidence of encephalitis and was positive for HSV by immunohistochemistry. This fatal case of HSE emphasizes the limitations of HSV PCR and the importance of clinical suspicion in the diagnosis and management of this disease

    Alcohol consumption and cognitive performance: a <scp>M</scp> endelian randomization study

    Aims: To use Mendelian randomization to assess whether alcohol intake was causally associated with cognitive function. Design: Mendelian randomization using a genetic variant related to alcohol intake (ADH1B rs1229984) was used to obtain unbiased estimates of the association between alcohol intake and cognitive performance. Setting: Europe. Participants: More than 34000 adults. Measurements: Any versus no alcohol intake and units of intake in the previous week was measured by questionnaire. Cognitive function was assessed in terms of immediate and delayed word recall, verbal fluency and processing speed. Findings: Having consumed any versus no alcohol was associated with higher scores by 0.17 standard deviations (SD) [95% confidence interval (CI)=0.15, 0.20] for immediate recall, 0.17 SD (95% CI=0.14, 0.19) for delayed recall, 0.17 SD (95% CI=0.14, 0.19) for verbal fluency and 0.12 SD (95% CI=0.09, 0.15) for processing speed. The minor allele of rs1229984 was associated with reduced odds of consuming any alcohol (odds ratio=0.87; 95% CI=0.80, 0.95; P=0.001; R2=0.1%; F-statistic=47). In Mendelian randomization analysis, the minor allele was not associated with any cognitive test score, and instrumental variable analysis suggested no causal association between alcohol consumption and cognition: -0.74 SD (95% CI=-1.88, 0.41) for immediate recall, -1.09 SD (95% CI=-2.38, 0.21) for delayed recall, -0.63 SD (95% CI=-1.78, 0.53) for verbal fluency and -0.16 SD (95% CI=-1.29, 0.97) for processing speed. Conclusions: The Mendelian randomization analysis did not provide strong evidence of a causal association between alcohol consumption and cognitive ability

    Recent advances in the understanding of Chlamydophila pecorum infections, sixteen years after it was named as the fourth species of the Chlamydiaceae family

    Chlamydophila pecorum found in the intestine and vaginal mucus of asymptomatic ruminants has also been associated with different pathological conditions in ruminants, swine and koalas. Some endangered species such as water buffalos and bandicoots have also been found to be infected by C. pecorum. The persistence of C. pecorum strains in the intestine and vaginal mucus of ruminants could cause long-term sub-clinical infection affecting the animal’s health. C. pecorum strains present many genetic and antigenic variations, but coding tandem repeats have recently been found in some C. pecorum genes, allowing C. pecorum strains isolated from sick animals to be differentiated from those isolated from asymptomatic animals. This review provides an update on C. pecorum infections in different animal hosts and the implications for animal health. The taxonomy, typing and genetic aspects of C. pecorum are also reviewed

    Comprehensive Dissection of PDGF-PDGFR Signaling Pathways in PDGFR Genetically Defined Cells

    Get PDF
    Despite the growing understanding of PDGF signaling, studies of PDGF function have encountered two major obstacles: the functional redundancy of PDGFRα and PDGFRβ in vitro and their distinct roles in vivo. Here we used wild-type mouse embryonic fibroblasts (MEF), MEF null for either PDGFRα, β, or both to dissect PDGF-PDGFR signaling pathways. These four PDGFR genetically defined cells provided us a platform to study the relative contributions of the pathways triggered by the two PDGF receptors. They were treated with PDGF-BB and analyzed for differential gene expression, in vitro proliferation and differential response to pharmacological effects. No genes were differentially expressed in the double null cells, suggesting minimal receptor-independent signaling. Protean differentiation and proliferation pathways are commonly regulated by PDGFRα, PDGFRβ and PDGFRα/β while each receptor is also responsible for regulating unique signaling pathways. Furthermore, some signaling is solely modulated through heterodimeric PDGFRα/β
