HIV-related neuropsychological impairment and immunodeficiency. CD8+ lymphocytes and neopterin are related to HIV-encephalopathy

The relationship between neuropsychological test performance and immunological parameters was studied in 52 HIV-positive patients within different stages of the infection. All subjects were neuropsychologically tested, the CD4 + and CD8 4- lymphocyte count were measured in peripheral blood, and the concentration of neopterin and HIV-p24 antigen were measured in serum. Ten patients with AIDS were defined as neuropsychologically impaired. The CD8 + cell count was the only immunological parameter that could significantly discriminate between AIDS patients with and without neuropsychological impairment. For the total group, significant positive correlations were found between neuropsychological test results and the number of CD8 + and CD4 + lymphocytes, and significant negative correlations were observed between serum concentration of neopterin and neurocognitive function. Regression analyses showed that up to 51% of the variance in test performance could be explained by CD8 + cells and neopterin concentration. The possible role of CD8 + lymphocytes and neopterin in the pathogenesis of HIV-related CNS-dysfunction is discussed.

The roles of dispositional optimism and pessimism in hiv disease progression

Relationships between dispositional optimism and pessimism and the course of HIV infection, determined by changes in viral load and CD4 counts, were studied in a longitudinal cohort of 412 patients on antiretroviral therapy (ART). Multiple regression analyses controlling for baseline levels of disease status, ethnicity, and depressive symptoms demonstrated that higher pessimism at baseline was associated with higher viral load at follow-up (average of 18 months later). Optimism at baseline had a curvilinear relationship with CD4 counts at follow-up. Moderate levels of optimism at baseline predicted the highest CD4 counts at follow-up. Although optimism and pessimism were associated with specific health behaviors (e.g., ART adherence, cigarette use, drug use, dietary practices), none of these behaviors mediated the optimism/pessimism effects. The biologic and behavioral mediators of associations of personality variables with the course of treated HIV infection deserve continued investigation.     

Cross-sectional and Longitudinal associations in coping strategies and physical health outcomes among HIV-Positive youth

This study assessed whether coping styles had an influence on physical health outcomes either concurrently or longitudinally in a sample of HIV-positive youth. Coping styles were characterized as positive, passive, depressive withdrawal, and escapist. A cross-sectional latent variable analysis (N = 279) assessed associations among environmental stress, self-esteem, social support, coping styles, AIDS symptoms, and CD4 count. A more restricted longitudinal analysis (N = 174) tested associations among earlier environmental stress, self-esteem, coping styles, and AIDS symptoms at follow-up. CD4 count was not associated with coping styles in the cross-sectional analysis. Concurrent AIDS symptoms were significantly predicted by depressive withdrawal and environmental stress. A passive coping style modestly predicted more AIDS symptoms longitudinally. Correlates of perceived health and well-being of persons with HIV/AIDS are important to investigate in addition to more objective measures such as CD4 count that may not be amenable to change through coping style interventions alone.     

定量组织速度成像评价酒精性心肌损害左室功能的价值

为了评估定量组织速度成像(QTVI)在评价大量饮酒后心肌损害左室功能改变方面的价值,我们对饮酒量符合酒精性心肌病诊断标准患者21例(B组,每日饮白酒≥150g或啤酒4瓶,每周6天~7天,10年以上),30例健康志愿者(A组,正常对照组)进行常规超声参数及QTVI参数测定,包括:二尖瓣环收缩期峰值速度(Vs)、舒张早期运动速度(Ve)、舒张晚期运动速度(Va)等。结果显示,B组常规各超声参数与A组比较差异有显著性统计学意义(P0.01)。QTVI参数与A组比较Va减低(P0.05),Vs、Ve、Ve/Va显著减低(P0.01)。提示QTVI技术能够有效地评估酒精性心肌损害病左室功能的改变。

Self regard and concealment of homosexuality as predictors of CD4+ cell count over time among hiv seropositive gay men

Living with HIV can challenge core features of a person’s sense of identity and ultimately lead to a diminished sense of self regard. Self-regard has been defined as the extent to which a person experiences an integrated sense of identity. Gay men with HIV may also face struggles related to their identity in deciding whether to disclose or conceal their homosexuality. This study examined whether concealment of homosexuality and a person’s sense of self regard would be associated with CD4+ cell count over time among HIV seropositive gay men. 53 HIV seropositive gay men completed questionnaires at one time point. CD4+ cell counts were measured at the time of questionnaire completion and 24 months later. Greater self regard at baseline was associated with higher CD4+ counts at 24 months. The association between baseline self regard and CD4+ count at 24 months was strongest among persons with less concealment of homosexuality.     

Confirmation of an Inhibitory Control Deficit in Attention-Deficit/Hyperactivity Disorder

The objective of this study was to determine whether deficient inhibitory control distinguishes children with a diagnosis of attention-deficit/hyperactivity (ADHD) disorder, conduct disorder (CD), and comorbid ADHD + CD from normally developing children. Participants were rigorously diagnosed children (age 7 to 12 years) with ADHD (N = 72), CD (N = 13) or ADHD + CD (N = 47) and 33 control children (NC). We studied inhibitory control using the stop-signal paradigm, a laboratory task that assessed the ability to inhibit an ongoing action. The ADHD group had significantly impaired inhibitory control compared to NC, CD, and ADHD + CD children. These results indicate that children with ADHD have deficient inhibition as measured in the stop-signal paradigm and that ADHD occurring in the presence of ADHD + CD may represent a phenocopy of CD rather than a variant of ADHD.
