H2O2-producing commensal lactobacilli inhibit N. gonorrhoeae in vitro and clinical data suggest they are associated with reduced risk of gonorrhea. Here we pre-colonized mice with Lactobacillus crispatus and then challenged them with N. gonorrhoeae to measure the effects of H2O2-producing lactobacilli on gonococcal infection. We found no difference in the duration of infection or number of gonococci recovered from untreated mice and mice colonized with L. crispatus. A gonococcal catalase mutant and a catalase, cytochrome C peroxidase mutant exhibited greater susceptibility to L. crispatus in vitro than wild type bacteria; however, recovery of these mutants from mice was not affected by L. crispatus. We also found no evidence that utilization of lactobacillus-produced lactate by N. gonorrhoeae balances the detrimental effects of H2O2 during infection. We conclude the relationship between lactobacilli and gonococci is complex and may be subject to factors that have not been reproduced in vitro.
Patient satisfaction is an indicator of quality of care received. Home-visit programs are associated with increased satisfaction and equivalent clinical outcomes but increased cost, compared with clinic visits. We hypothesized that home visits for routine well-child care would also be associated with increased satisfaction and equivalent outcomes. One thousand infants born at Tripler Army Medical Center were identified, and 630 were enrolled. Army and Air Force dependents received 2-week clinic visits. Navy and Marine Corps dependents were offered home visits. At 4 to 6 weeks, families completed a questionnaire. Maternal satisfaction and quality of anticipatory guidance were higher in the home-visit group. Clinical outcomes were equal. Home visits for routine well-child care are valid and are associated with greater maternal satisfaction, better anticipatory guidance, and equivalent clinical outcomes.
BackgroundHepatitis B virus (HBV) is endemic worldwide. Given significant rates of infectivity, all infants born to Hepatitis B surface antigen positive mothers need to receive treatment at birth, immunization and post-vaccination serologic testing. However, not all infants complete these requirements.FindingsWe performed a retrospective review of the management of infants born to Hepatitis B infected mothers at two large military hospitals in the United States that use a global electronic medical record to track patient results. We then compared these results to those recently published by the National Perinatal Hepatitis B Prevention Program (PHBPP), which does not include hospitals in the United States Military Healthcare System. Our results show that although all infants were managed appropriately at birth and immunization rates were very high, post vaccination follow-up testing rates were much lower than those seen in centers participating in the PHBPP. The rates of post vaccination serological testing were significantly higher for infants born to Hepatitis B e antigen positive mothers and those referred to a pediatric infectious disease specialist.ConclusionsDespite use of a global electronic medical record in the United States Military Healthcare System, management of HBV-exposed infants does not always follow recommended guidelines. These infants could benefit from a more systematic method of follow-up, similar to the PHBPP, to ensure HBV serologic testing is obtained after the vaccination series is complete.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
