OBJECTIVE: To compare the vaginal microbiome in women who have undergone spontaneous abortion with a gestational age of less than 20 weeks to that of women who have a continued pregnancy of the same gestational age.
METHODS: Cross-sectional comparative research design.
METHODS: The study was conducted in a tertiary care hospital of North Karnataka, India. In this rural area, many women lack awareness of prenatal care and women\'s health information. Given rising rates of spontaneous abortion, studying the impact of the vaginal microbiome on pregnancy outcomes is crucial for raising local awareness.
METHODS: Two hundred women; 100 experienced spontaneous abortion within 20 weeks\' gestation, and 100 maintained pregnancy with the same gestational age.
METHODS: Vaginal swab was used to detect participants\' vaginal microbiota. DNA was extracted from the vaginal samples; the 16S ribosomal RNA sequencing method was used to identify the organisms present.
RESULTS: A pathogen detection rate of 13.15% (n = 200 women) was found in vaginal cultures. The percentages of bacterial detection in women who had spontaneous abortion and those whose pregnancies continued were 19.9% and 7.9%, respectively (p < .05). Compared to women who sustained their pregnancy, women who experienced spontaneous abortion had five common species: Escherichia coli (48%), Enterococcus faecalis (28%), Enterococcus faecium (12%), Pseudomonas fluorescens (7%), and Pseudomonas cedrina (5%); the most prevalent species among those with sustained pregnancy were Lactobacillus iners (58%), Lactobacillus crispatus (32 %), and E. coli (10%; p < .05).
CONCLUSIONS: The vaginal microbiomes of women with spontaneous abortion were more varied and irregularly distributed with bacteria. The bacteria identified could affect a woman\'s pregnancy outcome and perhaps be associated with spontaneous abortion. It is vital for nurses to provide education to women who are in the fertile period regarding prenatal screening, sexually transmitted infections, and perineal care.

The effect of hepatitis B virus (HBV) replication during pregnancy on the outcomes of pregnancies remains to be elucidated.
This study aimed to investigate the association between HBV replication and adverse maternal and infant outcomes.
We retrospectively analysed the clinical data of 836 pregnant inpatients with hepatitis B surface antigen positivity who delivered at two provincial tertiary grade A hospitals in the Fujian province between June 2016 and October 2020.
The incidence of intrahepatic cholestasis of pregnancy, hypertensive syndrome complicating pregnancy, gestational diabetes mellitus, preterm birth, macrosomia, growth restriction, and vaginal infections did not differ in the HBV replication and non-replication groups (p > 0.05); however, the rates of caesarean section (p = 0.017; OR, 1.423; 95% CI, 1.065-1.902) and neonatal jaundice (p < 0.001; OR, 2.361; 95% CI, 1.498-3.721) were higher in the replication group than that in the non-replication group. After using propensity score analysis to adjust for alanine transaminase and aspartate aminotransferase levels in both groups, the replication group was still found to have an increased risk for caesarean section (p < 0.001; OR, 2.367; 95% CI, 1.668-3.359) and their infants had higher rates of neonatal jaundice (p < 0.001; OR, 12.605; 95% CI, 4.456-35.656).
Our findings contribute to a better understanding of the association between maternal HBV replication status and perinatal outcomes. Pregnant women with HBV replication face an increased risk of caesarean section, and their infants appear to have a higher risk for neonatal jaundice.

To explore the pathogen distribution in Chinese females with vaginitis.
This retrospective study included Chinese females with vaginitis admitted at the outpatient department of the Gynecology Clinic of the Second Affiliated Hospital of Kunming Medical University between January 2013 and June 2013. Data on the vaginal pathogens and inflammation were analyzed.
The vaginal secretions from 15,601 gynecologic outpatients were abnormal, including 8547 (54.78%) with vaginal infection and 7054 (45.22%) without. In patients with vaginal infections, a single infection was observed in 69.72% (5959/8547) of them, and mixed infection was observed in 30.28% (2588/8547). The differences in age and inflammation grade between the infection and no-infection groups were statistically significant (all P < 0.001). In addition, multiple types of vaginitis could be diagnosed in patients with mixed infections.
About half of the Chinese women with abnormal vaginal secretions are positive for pathogens in the study period. Patients\' age and inflammation grade are associated with co-infection. From the public health perspective, this study suggests that the importance of vaginal hygiene should be enforced in Chinese women.

Due to the excessive use of antibiotic and antimycotic treatments, the risk of resistant microbes and fungi is rapidly emerging. Previous studies have demonstrated that many women with (recurrent) urinary tract infection (UTI) and/or vaginal infections (VIs) welcome alternative management approaches to reduce the use of antibiotics and antifungals and avoid short- and long-term adverse effects. This study aims to determine which complementary medicine (CM) and self-care strategies are being used by women suffering from (recurrent) UTI and VI in The Netherlands and how they perceive their effectiveness in order to define directions for future research on safety, cost-effectiveness, and implementation of best practices. A cross-sectional online survey was performed among women, ≥18 years old, with a history of UTIs; 162 respondents were included in the data analysis, with most participants aged between 50 and 64 years (36.4%). The women reported having consulted a CM practitioner for UTI-specific symptoms (23.5%) and VI-specific symptoms (13.6%). Consultations of homeopaths, acupuncturists, and herbal physicians are most often reported. Overall, 81.7% of the women suffering from UTI used complementary or self-care strategies besides regular treatment, and 68.7% reported using CM/self-care strategies to treat vaginal symptoms. UTI- related use of cranberries (51.9%), vitamin C (43.8%), and D-mannose (32.7%) were most reported. Perceived effectiveness was mostly reported for homeopathic remedies and D-mannose. The results showed a substantial burden of UTI and VI on daily and sexual activities. Besides the frequency of use, the indication of perceived effectiveness seems to be an important parameter for further and rigorously designed research to encourage nonantibiotic/antifungal treatment implementation into daily clinical practice.

Bacterial vaginosis (BV) represents the most frequent vaginal infection in women of childbearing age. The aim of this study was to characterise episodes of BV among adult Spanish women and their management with dequalinium chloride (DQC). Data from 573 DQC-treated BV adult women was obtained on medical records and questionnaires. The study shows that 20.6% had presented vaginal infections previously. Comorbid candidosis was significantly associated to other symptoms, such as pruritus or leucorrhoea. Most patients (64.3%) indicated a moderate-strong impact of the BV episode on their sexual life. After treatment, 84.8% of patients reported no BV symptoms. Patients were given instructions to prevent relapses. Most patients (83.1%) rated DQC as \'satisfactory\' or \'very/extremely satisfactory\' regarding symptom relief, prevention or treatment of the episode of BV. In conclusion, this study provides a better understanding of BV episodes and the impact of the treatment with DQC in real clinical practice in Spanish patients.IMPACT STATEMENTWhat is already known on this subject? Bacterial vaginosis (BV) is the most commonly reported vaginal infection among women of childbearing age. Despite the availability of antibiotic medications for the treatment of BV, management of this condition remains challenging. In fact, recurrence of BV has been reported for up to 50% of cases. However, antiseptic agents are considered an effective option for BV treatment.What the results of this study add? The study provides a better understanding of the prevalent symptomatology and the impact on quality of life of women with BV. Moreover, it has been observed that antiseptic dequalinium chloride (DQC) efficiently reduces symptoms and improves quality of life of the patients during episodes of BV.What the implications are of these findings for clinical practice and/or further research? In the context of the World Health Organisation recommendations on the rational use of antibiotics, we believe that the use of DQC may be a good alternative to antibiotics as a therapy for BV.

Pregnancy outcomes and women\'s health are directly affected by vaginal microbiota. This microbiota consists of a dynamic ecosystem of various microbes in different ratios, which in healthy conditions protect the vaginal epithelium from infections. However, cases of vaginal infection are regularly diagnosed in women of reproductive age, contributing to more severe outcomes. Therefore, our main goal was to determine the prevalence of bacterial vaginosis (BV), aerobic vaginitis (AV), and vulvovaginal candidiasis (VVC) among Ecuadorian pregnant and non-pregnant women. A cross-sectional study was conducted among 217 women between 13 and 40 years old seeking primary healthcare in Carlos Andrade Marin Hospital (HCAM), Gynecological-Obstetric Hospital Isidro Ayora (HGOIA) and Center for Teaching Health Cipriana Dueñas during October 2018 to February 2019. The classical characterization of the vaginal microbiota was performed through microscopy by the Nugent criteria to evaluate the presence of BV, healthy and intermediate microbiota, by the criteria of Donders to determine the presence of AV and by the Marot-Leblond criteria to diagnose VVC. DNA extraction from vaginal samples and Polymerase Chain Reaction (PCR) analysis was performed to characterize the presence of Gardnerella spp., Mobiluncus mulieris, Escherichia coli, Enterococcus spp., and Lactobacillus spp. Finally, quantification of the lactobacilli was performed by quantitative real-time PCR (qPCR) for samples from women with normal vaginal microbiota and women with AV. Our results showed 52% of women with healthy microbiota, 7% with intermediate microbiota, and 41% with vaginal dysbiosis, comprising 27% with AV, 8% with BV and 4% with VVC and 2% with co-infections or co-dysbiosis. Additionally, a higher amount of lactobacilli were found in pregnant women when compared to non-pregnant women, while AV cases were characterized by a significant drop of Lactobacillus spp., more precisely, between 1E3 and 1E5 colony forming units (CFU)/ml. Finally, women with normal vaginal microbiota showed an average load of lactobacilli between 1E6 and 1E7 CFU/ml. This pilot study showed no statistically significant differences between pregnant and non-pregnant women, pointing to the possibility to use lactobacilli quantification for the prevention of future vaginal infections.

Background: Bacterial vaginosis is the most frequent condition associated to the vaginal microbiota imbalance, affecting about the 40-50% of women in the world. Even if antibiotics are effcetive for bacterial vaginosis treatment a long-term recurrence rates, higher than 70%, is recorded. Lactoferrin is an iron-binding glycoprotein with bacteriostatic and bactericidal properties. It owns the ability to protect the host against infection, by binding and regulating the iron needed for the bacterial proliferation. Objective: The present study was an open prospective randomized trial (registration no. SHI-EVE-2014.01) aimed at characterizing the bacterial biota of women affected by bacterial vaginosis (BV) and assessing the effects of two different lactoferrin concentrations (100 mg and 200 mg vaginal pessaries) on the composition and dynamics of the vaginal bacterial biota. Design: Sixty women with BV were recruited and randomized into two groups to receive lactoferrin pessaries for 10 days. Clinical evaluation was based on Amsel criteria and Nugent scores. Culture-dependent methods and Ion Torrent PGM sequencing of the 16S rRNA gene were applied to study in depth the overall structure of the vaginal bacterial biota and its dynamics during the treatment. Results: Vaginal lactoferrin administration modified the vaginal microbiota composition in patients with BV. During treatment, both 100 mg and 200 mg lactoferrin vaginal pessaries significantly decreased the occurrence of bacteria associated with BV, such as Gardnerella, Prevotella, and Lachnospira, and increased the occurrence of Lactobacillus species. The bacterial biota balance was maintained up to 2 weeks after treatment only in women treated with 200 mg lactoferrin pessaries. Conclusions: This study indicates that lactoferrin could be proposed as an alternative therapeutic approach for BV. Our data showed, for the first time, the dominance of Lactobacillus helveticus species during and after vaginal lactoferrin treatment.

OBJECTIVE: To investigate the risk for preterm birth associated with vaginal infections in pregnancies after a loop electrosurgical excision procedure (LEEP), compared with women with no prior LEEP.
METHODS: Multicentre retrospective cohort study.
METHODS: USA.
METHODS: Women with LEEP between 1996 and 2006 were compared with two unexposed groups who had cervical biopsy or Pap test, without any other cervical procedure, in the same calendar year.
METHODS: The first pregnancy progressing beyond 20 weeks of gestation in women with prior LEEP was compared with pregnancy in women without LEEP. Stratified analysis according to the presence or the absence of vaginal infection during pregnancy was used to investigate whether the risk for preterm birth differed according to the presence or the absence of infection. The interaction between LEEP and vaginal infection was investigated using multivariable logistic regression with interaction terms, as well as the Mantel-Haenszel test for homogeneity.
METHODS: Spontaneous preterm birth (<37 and <34 weeks of gestation).
RESULTS: Of 1727 patients who met the inclusion criteria, 34.4% (n = 598) underwent LEEP prior to an index pregnancy. There was no increased risk for vaginal infections among women with LEEP compared with women without LEEP. Chlamydia infection and LEEP demonstrated significant interaction, suggesting that the presence of chlamydia infection in women with a history of LEEP augments the risk for preterm birth, compared with women with no history of LEEP.
CONCLUSIONS: Vaginal infections during pregnancy in women with a history of LEEP may be associated with an increased risk for preterm birth, compared with women with no history of LEEP.
