Social Capital and Quality of Life Among People Living With HIV/AIDS in Southeast China.

A cross-sectional study was conducted with 261 people living with HIV (PLWH) in Southeast China. A social capital questionnaire was used to measure social capital dimensions (trust, social connection, and social participation). A Chinese version of the Medical Outcomes Study HIV Health Survey (MOS-HIV) was used to assess Quality of Life (QoL); Physical Health Summary Scores (PHS) and Mental Health Summary Scores (MHS) were calculated. Multiple regression assessed whether social capital and its dimensions were associated with PHS and MHS. After controlling for sociodemographics and HIV-related factors, lower PHS scores were found among participants with low overall social capital (P < .01) and low trust (P < .001). Lower MHS scores were found among participants with low overall social capital (P < .001), low trust (P < .001) and low social connection (P < .01). Our findings identify potential intervention targets to improve QoL among PLWH in Southeast China, including the promotion of social capital.

Meta-analysis: is combination of tetracycline and amoxicillin suitable for Helicobacter pylori infection?

AIM: To access the efficacy of combination with amoxicillin and tetracycline for eradication of Helicobacter pylori (H. pylori), thus providing clinical practice guidelines. METHODS: PubMed, EMBASE, Cochrane Central Register of Controlled Trials, Science Citation Index, China National Knowledge Infrastructure, Wanfang, and Chinese Biomedical Literature databases and abstract books of major European, American, and Asian gastroenterological meetings were searched. All clinical trials that examined the efficacy of H. pylori eradication therapies and included both tetracycline and amoxicillin in one study arm were selected for this systematic review and meta-analysis. Statistical analysis was performed with Comprehensive Meta-Analysis Software (Version 2). Subgroup, meta-regression, and sensitivity analyses were also carried out. RESULTS: Thirty-three studies met the inclusion criteria. The pooled odds ratio (OR) was 0.90 (95%CI: 0.42-1.78) for quadruple therapy with amoxicillin and tetracycline vs other quadruple regimens, and total eradication rates were 78.1% by intention-to-treat (ITT) and 84.5% by per-protocol (PP) analyses in the experimental groups. The pooled eradication rates of 14-d quadruple regimens with a combination of amoxicillin and tetracycline were 82.3% by ITT and 89.0% by PP, and those of 10-d regimens were 84.6% by ITT and 93.7% by PP. The OR by ITT were 1.21 (95%CI: 0.64-2.28) for triple regimens with amoxicillin and tetracycline vs other regimens and 1.81 (95%CI: 1.37-2.41) for sequential treatment with amoxicillin and tetracycline vs other regimens, respectively. CONCLUSION: The effectiveness of regimens employing amoxicillin and tetracycline for H. pylori eradication may be not inferior to other regimens, but further study should be necessary.

[A case-control study on risk factors for advanced schistosomiasis japonica].

OBJECTIVE: To investigate risk factors for the development of advanced schistosomiasis. METHODS: The case-control study was designed with a match of 1:1 and 1:2. Healthy persons and chronic schistosomiasis patients were used as control. Each group was composed of 213 cases. Items investigated included: history of schistosomiasis and treatment, exposure to the contaminated water, social-economical condition and nutritional status, other concomitant diseases. Cellular and humoral immunity, HBVMs and ABO blood groups were also detected. Statistical analysis was performed by 1:1 and 1:2 matched single and stepwise conditional logistic regression analysis with SAS software. RESULTS: By stepwise conditional logistic regression analysis, it was revealed that number of schistosomiasis examination (OR = 1.168-1.311), interval from first infection to last treatment(OR = 1.142), interval from first infection to this investigation (OR = 1.089), HBsAg+ (OR = 4.683-10.759), HBcAb+ (OR = 2.873), HBsAg+ + HBeAb+ + HBcAb+ (OR = 7.64) were risk factors of developing advanced schistosomiasis. The average living space and cellular immunity were lower in advanced schistosomiasis patients than others. No association was found between advanced schistosomiasis and ABO blood groups. CONCLUSION: The development of advanced schistosomiasis is associated with repeated infections, and delayed or incomplete treatment. Combined infection with hepatitis B, poor socio-economic conditions and impaired cellular immunity may increase the pathogenetic risk of schistosomiasis.
