HIV infection in rural villages of Cameroon

OBJECTIVE: To evaluate HIV-1 antibody seroprevalence and risk factors for HIV seropositivity in rural areas of Cameroon. METHOD: The prevalences of HIV antibodies in 53 villages in rural Cameroon visited during May-October 2000 were determined with an HIV1/2 rapid assay, standard ELISA, and western blot. Demographic data and risk factors were elicited via face-to-face interviews with a structured questionnaire. RESULTS: HIV seroprevalence was 5.8% (243/4156, 95% confidence interval [CI] = 5.1-6.6) overall, 6.3% (151/2394, 95% CI = 5.4-7.4) among females and 5.2% (92/1762, 95% CI = 4.3-6.4) among males. HIV seroprevalence among persons aged 15 - 70 years did not differ significantly by province (5.6% in Center, 4.5% in East, 6.9% in South, and 5.8% in South-West) ( =.10). Analysis of age- and gender-standardized prevalence by village across provinces indicated a near-significant difference (nonparametric Wilcoxon signed rank test, =.06), with highest prevalence in South-West, followed by South, Center, and East. Multivariate analysis revealed that single women were significantly more likely to be HIV seropositive than were married or widowed women. Women with a history of sexual relations while traveling were at significantly increased risk of HIV seropositivity (OR adjusted for age and marital status = 2.4, 95% CI = 1.4-9.7). Among men, those who reported ever having a sexually transmitted disease were at significantly increased risk of HIV-seropositivity (OR adjusted for age = 1.8, 95% CI = 1.1-2.8). CONCLUSION: We have documented a wide range of HIV prevalences among rural villages of Cameroon. Age, marital status (in women) and sexual risk factors appear to be associated with HIV infection in this setting.     

围术期焦虑及干预

本文以自评、医师评定两种方式对腹部手术患者１０３例（除外精神科病史）进行围术期焦虑及干预的描述性研究。发现术前明显焦虑者占３０％，疑有焦虑者占３４％，无焦虑者占３６％。特质焦虑直接影响术前状态焦虑，疾病、手术因素影响术后焦虑，此时特质焦虑仍起作用。支持性心理治疗能降低术前焦虑，提高无并发症者满意程度，但对躯体预后无直接影响。另外，腹部手术患者入院时血皮质醇浓度高于正常人群。     

Impact of a Federal Healthy Start Program on Feto-infant Morbidity Associated with Absent Fathers: A Quasi-experimental Study

The absence of fathers during pregnancy increases the risk of feto-infant morbidities, including low birth weight (LBW), preterm birth (PTB), and small-for-gestational age. Previous research has shown that the Central Hillsborough Healthy Start project (CHHS)—a federally funded initiative in Tampa, Florida—has improved birth outcomes. This study explores the effectiveness of the CHHS project in ameliorating the adverse effects of fathers’ absence during pregnancy. This retrospective cohort study used CHHS records linked to vital statistics and hospital discharge data (1998–2007). The study population consisted of women who had a singleton birth with an absent father during pregnancy. Women were categorized based on residence in the CHHS service area. Propensity score matching was used to match cases (CHHS) to controls (rest of Florida). Conditional logistic regression was employed to generate odds ratios (OR) and 95 % confidence intervals (CI) for matched observations. Women residing in the CHHS service area were more likely to be high school graduates, black, younger (<35 years), and to have adequate prenatal care compared to controls (p < 0.01). These differences disappeared after propensity score matching. Mothers with absent fathers in the CHHS service area had a reduced likelihood of LBW (OR 0.76, 95 % CI 0.65–0.89), PTB (OR 0.72, 95 % CI 0.62–0.84), very low birth weight (OR 0.50, 95 % CI 0.35–0.72) and very preterm birth (OR 0.48, 95 % CI 0.34–0.69) compared to their counterparts in the rest of the state. This study demonstrates that a Federal Healthy Start project contributed to a significant reduction in adverse fetal birth outcomes in families with absent fathers.     

The EuroSIDA study: 25 years of scientific achievements

The EuroSIDA study was initiated in 1994 and follows adult people living with HIV (PLHIV) in 100 collaborating clinics across 35 countries covering all European regions, Israel and Argentina. The study aims to study the long‐term virological, immunological and clinical outcomes of PLHIV and to monitor temporal changes and regional differences in outcomes across Europe. Annually collected data include basic demographic characteristics, information on AIDS‐ and non‐AIDS‐related clinical events, and details about antiretroviral therapy (ART), hepatitis C treatment and other medications, in addition to a range of laboratory values. The summer 2016 data set held data from a total of 23 071 individuals contributing 174 481 person‐years of follow‐up, while EuroSIDA’s unique plasma repository held over 160 000 samples. Over the past 25 years, close to 300 articles have been published in peer‐reviewed journals (h‐index 52), covering a range of scientific focus areas, including monitoring of clinical and virological outcomes, ART uptake, efficacy and adverse events, the influence of hepatitis virus coinfection, variation in the quality of HIV care and management across settings and regions, and biomarker research. Recognizing that there remain unresolved issues in the clinical care and management of PLHIV in Europe, EuroSIDA was one of the cohorts to found The International Cohort Consortium of Infectious Disease (RESPOND) cohort consortium on infectious diseases in 2017. In celebration of the EuroSIDA study’s 25th anniversary, this article aims to summarize key scientific findings and outline current and future scientific focus areas.     

Differences between bipolar compression and ultrasonic devices for parenchymal transection during laparoscopic liver resection

Objectives

In laparoscopic liver resection, multiple options for parenchymal transection techniques exist; however, none have emerged as superior. The aim of this study was to compare operative characteristics and outcomes between bipolar compression and ultrasonic devices used for parenchymal transection during laparoscopic liver resection.

Methods

A review of a prospective hepatopancreatobiliary database from December 2002 to August 2009 identified 54 patients who underwent laparoscopic liver resection with parenchymal division using either a bipolar compression (n = 35) or an ultrasonic (n = 19) device. Operative data, histology and 90-day complication rates were compared between the groups using analysis of variance (anova) and Pearson''s chi-squared test.

Results

The two groups did not differ significantly in terms of age, body mass index, parenchymal steatosis/inflammation or number of segments resected. A shorter time of parenchymal transection was noted for the bipolar compression device (median: 35 min; range: 20–65 min) vs. the ultrasonic device (median: 55 min; range: 29–75 min) (P < 0.001). Median total operative time was also shorter using the bipolar compression device (130 min) than the ultrasonic device (180 min) (P = 0.050). No significant differences between device groups were noted for estimated blood loss, complications of any type or liver-specific complications.

Conclusions

Bipolar compression devices may offer advantages over ultrasonic devices in terms of decreased transection time and total operative time. No differences in postoperative complications in laparoscopic liver resection emerged between patients operated using the devices.     

The Association Between HIV/AIDS During Pregnancy and Fetal Growth Parameters in Florida: A Population Based Study

In this population-based retrospective study, we sought to investigate the association between HIV/AIDS during pregnancy and adverse birth outcomes, including low birth weight (LBW), very low birth weight (VLBW), preterm birth (PTB), very preterm birth (VPTB), and small for gestational age (SGA), among women in Florida by sociodemographic variables. Using data from Florida's maternally linked birth cohort files, we examined singleton live births in the state during 1998 to 2007 (N = 1,698,107). The study population was categorized based on the maternal HIV/AIDS status. Poisson regression models were used to generate adjusted rate ratios (ARR) to estimate the association between HIV/AIDS status and fetal growth parameters. The main outcome measures were fetal growth parameters, including LBW, VLBW, PTB, VPTB, and SGA. As compared to HIV/AIDS-negative women, mothers with HIV/AIDS had elevated risks for LBW (ARR = 1.40; 95% CI = 1.30-1.50), VLBW (ARR = 1.25; 95% CI = 1.04-1.51), SGA (ARR = 1.26; 95% CI = 1.17-1.35), PTB (ARR = 1.23; 95% CI = 1.03-1.47), and VPTB (ARR = 1.27; 95% CI = 1.20-1.36). Risk estimates for LBW and SGA were highest among Hispanics mothers with HIV/AIDS, while white mothers with HIV/AIDS had the highest risk levels for VLBW and PTB, compared to their HIV/AIDS negative counterparts. Our findings show that women with HIV/AIDS have elevated risks for inhibited fetal growth and shortened gestation with important racial/ethnic variation. This is the first known population-based study that reveals racial/ethnic differences in HIV/AIDS-related fetal growth morbidity outcomes.
