Intervention by community health workers (CHWs) is believed to prevent repeated childbearing among teenagers. This review investigated the effectiveness of CHWs in reducing repeated pregnancies and births among adolescents aged <20 years, 2 years after the delivery of their first child. Through electronic database and hand searching, experimental and/or observational studies were screened with their results undergoing systematic review and meta-analyses. Subgroup analyses were performed to further assess how study characteristics affected the pooled estimates and heterogeneity. A total of 11 eligible articles, from January 1980 to May 2015, were included. Seven studies evaluated repeated births and eight measured repeated pregnancies. Studies showed relevant disparities in terms of selected methodological aspects and program characteristics. Although most studies (n = 9) were either of “strong” or of “moderate” quality, only two of five finding a significant reduction exhibited a high level of quality as the other three failed to adjust results for confounders. Random effects modeling revealed an overall 30% decrease in repeated adolescent births (odds ratio = .70, confidence interval = .49–.99) among CHW-visited areas relative to nonvisited sites. On the other hand, no significant association was detected in terms of repeated pregnancies (odds ratio = .96, confidence interval = .70–1.28). [ABSTRACT FROM AUTHOR]

Background: Recent reports suggest that in-use contamination of intravenous infusates is uncommon in hospitals with good standards of care. Methods: We conducted a survey in a referral hospital in Mexico with good standards of care but no pharmacists to prepare intravenous infusates; we tested the a priori hypothesis that the contamination rate is zero. Using a sterile syringe, we took an initial infusate specimen at the time of recruitment, specimen 1, for culture. We took a second specimen, specimen 2, from administration sets that were maintained for 72 hours. Blood cultures were obtained at the discretion of the physicians caring for the patients. Results: We cultured 1093 infusate specimens from 621 administration sets comprising 421 patients. We obtained a specimen 1 from each of the enrolled sets and a specimen 2 from 472 sets (76%). We analyzed 10 significant cultures and obtained a global infusate contamination rate of 0.9% (10/1093; 95% CI: 0.5%-1.7%). Two cases of infusate-related bacteremia occurred, establishing a global rate of 0.003/72 infusion hours. Conclusions: Even in institutions with good nursing standards, endemic in-use infusate contamination may be a present danger. We must avoid the use of intravenous therapy whenever possible.

Objective: Existing evidence of predictors of repeated teenage pregnancy has not been assessed rigorously. This systematic review provides a comprehensive evaluation of protective and risk factors that are associated with repeated teenage pregnancy through a metaanalytical consensus.Data Sources: We used PubMed, EMBASE, CINAHL, ProQuest, PsychINFO, ScienceDirect, Scopus, and Web of Science databases from 1997-2015 and the reference list of other relevant research papers and related reviews.Study Eligibility Criteria: Eligibility criteria included (1) epidemiologic studies that analyzed factors associated with repeated pregnancy or birth among adolescents <20 years of age who were nulliparous or experienced at least 1 pregnancy, and (2) experimental studies with an observational component that was adjusted for the intervention.Study Appraisal and Synthesis Methods: We performed narrative synthesis of study characteristics, participant characteristics, study results, and quality assessment. We also conducted random-effects and quality-effects metaanalyses with meta-regression to obtain pooled odds ratios of identified factors and to determine sources of between-study heterogeneity.Results: Twenty-six eligible epidemiologic studies, most from the United States (n=24), showed >47 factors with no evidence of publication bias for each metaanalysis. Use of contraception (pooled odds ratio, 0.60; 95% confidence interval, 0.35-1.02), particularly long-acting reversible contraceptives (pooled odds ratio, 0.19; 95% confidence interval, 0.08-0.45), considerably reduced repeated teenage pregnancy risk. Among studies about contraception, the number of follow-up visits (adjusted coefficient, 0.72; P=.102) and country of study (unadjusted coefficient, 2.57; permuted P=.071) explained between-study heterogeneity. Education-related factors, which included higher level of education (pooled odds ratio, 0.74; 95% confidence interval, 0.60-0.91) and school continuation (pooled odds ratio, 0.53; 95% confidence interval, 0.33-0.84), were found to be protective. Conversely, depression (pooled odds ratio, 1.46; 95% confidence interval, 1.14-1.87), history of abortion (pooled odds ratio, 1.66; 95% confidence interval, 1.08-2.54), and relationship factors, such as partner support, increased the repeated teenage pregnancy risk.Conclusion: Contraceptive use, educational factors, depression, and a history of abortion are the highly influential predictors of repeated teenage pregnancy. However, there is a lack of epidemiologic studies in low- and middle-income countries to measure the extent and characteristics of repeated teenage pregnancy across more varied settings.
