Anti-Tuberculosis Therapy-Induced Hepatotoxicity among Ethiopian HIV-Positive and Negative Patients

Background: To assess and compare the prevalence, severity and prognosis of anti-TB drug induced hepatotoxicity (DIH) in HIV positive and HIV negative tuberculosis (TB) patients in Ethiopia. Methodology/Principal Findings: In this study, 103 HIV positive and 94 HIV negative TB patients were enrolled. All patients were evaluated for different risk factors and monitored biochemically and clinically for development of DIH. Sub-clinical hepatotoxicity was observed in 17.3 % of the patients and 8 out of the 197 (4.1%) developed clinical hepatotoxicity. Seven of the 8 were HIV positive and 2 were positive for HBsAg. Conclusions/Significance: Sub-clinical hepatotoxicity was significantly associated with HIV co-infection (p = 0.002), concomitant drug intake (p = 0.008), and decrease in CD4 count (p = 0.001). Stepwise restarting of anti TB treatment was also successful in almost all the patients who developed clinical DIH. We therefore conclude that anti-TB DIH is a major problem in HIV-associated TB with a decline in immune status and that there is a need for a regular biochemical and clinical follow up for those patients who are at risk

Self-esteem memories: Feeling good about achievement success, feeling bad about relationship distress

College students and middle-aged adults provided memories of occasions when they felt especially good or especially bad about themselves. Probes directed the memory search to several age intervals during childhood, adolescence, and adulthood. Predominant themes represented in self-esteem memories differed consistently as a function of emotional valence. Memories of positive self-worth frequently focused on achievement/mastery themes, whereas memories of negative self-worth frequently focused on interpersonal/affiliation themes. When people evaluate the self through the lens of autobiographical memory, interpersonal distress is portrayed as especially damaging and achievement success is portrayed as especially enhancing. The asymmetry between positive and negative self-esteem memories is explained using multiple theoretical perspectives within social and personality psychology

Cultural scripts guide recall of intensely positive life events

Abstract In four studies, we examined the temporal distribution of positive and negative memories of momentous life events. College students and middle-aged adults reported events occurring from the ages of 8 to 18 years in which they had felt especially good or especially bad about themselves. Distributions of positive memories showed a marked peak at ages 17 and 18. In contrast, distributions of negative memories were relatively flat. These patterns were consistent for males and females and for younger and older adults. Content analyses indicated that a substantial proportion of positive memories from late adolescence described culturally prescribed landmark events surrounding the major life transition from high school to college. When the participants were asked for recollections from life periods that lack obvious age-linked milestone events, age distributions of positive and negative memories were similar. The results support and extend Berntsen and Rubin\u27s (2004) conclusion that cultural expectations, or life scripts, organize recall of positive, but not negative, events
