Alterations of the vaginal microbiome in healthy pregnant women positive for group B Streptococcus colonization during the third trimester.

BACKGROUND: Streptococcus agalactiae or group B Streptococcus (GBS) asymptomatically colonizes the genitourinary tracts of up to 30% of pregnant women. Globally, GBS is an important cause of neonatal morbidity and mortality. GBS has recently been linked to adverse pregnancy outcomes. The potential interactions between GBS and the vaginal microbiome composition remain poorly understood. In addition, little is known about the vaginal microbiota of pregnant Egyptian women. RESULTS: Using V3-V4 16S rRNA next-generation sequencing, we examined the vaginal microbiome in GBS culture-positive pregnant women (22) and GBS culture-negative pregnant women (22) during the third trimester in Ismailia, Egypt. According to the alpha-diversity indices, the vaginal microbiome of pregnant GBS culture-positive women was significantly more diverse and less homogenous. The composition of the vaginal microbiome differed significantly based on beta-diversity between GBS culture-positive and culture-negative women. The phylum Firmicutes and the family Lactobacillaceae were significantly more abundant in GBS-negative colonizers. In contrast, the phyla Actinobacteria, Tenericutes, and Proteobacteria and the families Bifidobacteriaceae, Mycoplasmataceae, Streptococcaceae, Corynebacteriaceae, Staphylococcaceae, and Peptostreptococcaceae were significantly more abundant in GBS culture-positive colonizers. On the genus and species levels, Lactobacillus was the only genus detected with significantly higher relative abundance in GBS culture-negative status (88%), and L. iners was the significantly most abundant species. Conversely, GBS-positive carriers exhibited a significant decrease in Lactobacillus abundance (56%). In GBS-positive colonizers, the relative abundance of the genera Ureaplasma, Gardnerella, Streptococcus, Corynebacterium, Staphylococcus, and Peptostreptococcus and the species Peptostreptococcus anaerobius was significantly higher. The Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways related to the metabolism of cofactors and vitamins, phosphatidylinositol signaling system, peroxisome, host immune system pathways, and host endocrine system were exclusively enriched among GBS culture-positive microbial communities. However, lipid metabolism KEGG pathways, nucleotide metabolism, xenobiotics biodegradation and metabolism, genetic information processing pathways associated with translation, replication, and repair, and human diseases (Staphylococcus aureus infection) were exclusively enriched in GBS culture-negative communities. CONCLUSIONS: Understanding how perturbations of the vaginal microbiome contribute to pregnancy complications may result in the development of alternative, targeted prevention strategies to prevent maternal GBS colonization. We hypothesized associations between inferred microbial function and GBS status that would need to be confirmed in larger cohorts.

Knowledge, attitude and practice towards abortion and post abortion care among Egyptian private obstetricians and gynaecologists.

OBJECTIVE: To assess the knowledge, attitude, and practice of private obstetricians and gynaecologists towards abortion, post-abortion care, and post-abortion family planning. PATIENTS AND METHODS: A cross-sectional study, from June 2017 to May 2018, using a self-administered questionnaire of 150 obstetricians/gynaecologists at private clinics, centres, hospitals in Ismailia, Egypt. The questionnaire was composed of four broad sections: section one was about the socio-demographic characteristics of the participants; section two was about physicians' knowledge, attitude and practices regarding abortion; section three was about their attitudes and practices regarding post-abortion family planning and screening for sexually transmitted diseases (STDs) in patients presenting for induced abortion; and section four was about the socio-demographic characteristics of women seeking induced abortion taken from the physicians' views. RESULTS: Only 15.2% of participants had performed an abortion for unwanted pregnancies at ≤12 weeks vs. 3.8% for unwanted pregnancies >12 weeks' gestation. The most common reason for not performing an abortion was religious prohibition (80.35% vs. 86.6% for unwanted pregnancy ≤12 and > 12 weeks, respectively). Social causes were the most common reason for seeking an induced abortion. None of the physicians used manual vacuum aspiration (MVA) for abortion or had received training in MVA. Post-abortion family planning counselling was offered by 20.5% of physicians, while 13.6% screened for STDs. CONCLUSIONS: The majority of private obstetricians/gynaecologists in Ismailia, Egypt, do not perform abortions for unwanted pregnancies because of their religious beliefs. Post-abortion screening for STDs and family planning services are not sufficiently integrated into post-abortion care.

The role of levonorgestrel intra-uterine system in the management of adenomyosis: A systematic review and meta-analysis of prospective studies.

INTRODUCTION: The levonorgestrel intrauterine system (LNG-IUS) is a long-acting hormone-releasing uterine device that has many non-contraceptive benefits. The study aims to assess the safety and efficacy of LNG-IUS in the management of adenomyosis. MATERIAL AND METHODS: We searched the following bibliographic databases: MEDLINE via PubMed, SCOPUS, Web of Science, Cochrane Central Register of Controlled Trials (CENTRAL), EMBASE and Google Scholar for the relevant studies which used LNG-IUS in management of patients with clinically or ultrasonographic diagnosed adenomyosis.The main outcome measures are pain score at the end of follow-up, bleeding, symptomatic relief, uterine volume (mL), endometrial thickness (mm) and/or hemoglobin level. RESULTS: Ten prospective studies (patients n = 551) were included. The overall effect estimates showed that the LNG-IUS led to significant reductions in pain score after 12 months (standardized mean difference [SMD[ -3.87, 95% confidence interval [CI] -5.51 to -2.23, P < .001), 24 months (SMD -5.56, 95% CI -9.80 to -1.32, P = .01) and 36 months of insertion (SMD -3.81, 95% CI -4.27 to -3.36, P < .001). Similarly, the Pictorial Blood Assessment Chart (PBAC) showed significant reduction up to 36 months after LNG-IUS insertion (SMD -2.32, 95% CI -2.91 to -1.73, P < .001). The LNG-IUS led to significant reductions in the uterine volume 12 months (SMD -.60, 95% CI -0.88 to -.31, P < .001) and 36 months after insertion (SMD -0.42, 95% CI -0.69 to -0.14, P = .003). CONCLUSIONS: LNG-IUS is a promising and effective option for the management of adenomyosis. Its use effectively reduced the severity of symptoms, uterine volume and endometrial thickness, and improved laboratory outcomes.
