Abstract
The prevalence of vaginal infection is increasing among women, especially at reproductive age. For proper eradication of infection, the effective concentration of a drug is required at the infection site. Therefore, local delivery is recommended to exert a direct therapeutic effect at the site action that causes a reduction in dose and side effects. The main focus of vaginal drug delivery is to enhance retention time and patient compliance. The high recurrence rate of vaginal infection due to the lack of effective treatment strategies opens the door for new therapeutic approaches. To combat these setbacks, intravaginal gene therapies have been investigated. High attention has been gained by vaginal gene therapy, especially for sexually transmitted infection treatment. Despite much research, no product is available in the market, although in vitro and preclinical data support the vaginal route as an effective route for gene administration. The main focus of this review is to discuss the recent advancement in miniaturized polymeric systems for intravaginal gene therapies to treat local infections. An overview of different barriers to vaginal delivery and challenges of vaginal infection treatment are also summarised.

Abstract
This study aimed to determine the prevalence of and risk factors associated with BV(bacterial vaginosis, BV), VVC (vulvovaginal candidiasis, VVC) and TV (trichomonal vaginitis, TV) among non-pregnant women. Among 770 women included in analyses, surveyed using a questionnaire and subsequently diagnosed with BV, VVC and TV via Gram staining and vaginal swab microscopy. Vaginal infections were prevalent in 31.30%, with BV being the most prevalent (21.35%). Single-variable analysis revealed that an age of 20-29 years (odds ratio [OR] = 2.31, 95% CI: 1.24-4.29; p = .007) and lack of education (OR = 0.50, 95% CI: 0.28-0.89; p = .018) were significantly associated with BV. However, an age of 30-39 years was significantly associated with VVC (OR = 2.12, 95% CI: 1.03-4.38; p = .038). Multivariable analysis confirmed that miscarriage was an independent predictor of BV and VVC. Miscarriage was significantly associated with the incidence of BV and VVC (OR = 1.680, 95% CI: 1.146-2.462; p = .011 and OR = 2.04, 95% CI: 1.30-3.20; p = .002, respectively). In conclusion, BV appears to be the predominant cause of vaginitis, risk factors for vaginitis include age and level of education and miscarriage.IMPACT STATEMENTWhat is already known on this subject? Inflammation of the vagina, or vaginitis, is caused by various infectious and non-infectious factors. The most common causes of infectious vaginitis are BV, VVC and TV. Kunming located at the southwestern border of China, However, there is still no systematic research investigating the status of vaginitis infection in Yunnan Province. Therefore, the present study aimed to determine the prevalence of these vaginal infections; BV, VVC, and TV, among women of childbearing age, and to assess the prevalence of vaginal infections and the associated risk factors.What do the results of this study add? In our study we found that vaginal infections were prevalent in 31.30% of reproductive-age women, with BV being the most prevalent (21.35%). We believe that our study makes a significant contribution to the literature because we report that BV appears to be the predominant cause of vaginitis, followed by VVC and TV. Risk factors for vaginitis include age, miscarriage and level of education.What are the implications of these findings for clinical practice and/or further research? This study aimed to determine the prevalence of these vaginal infections, BV, VVC and TV, and to assess the prevalence of vaginal infections and the associated risk factors. Health education interventions are recommended to raise women's awareness of vaginitis and its prevention.

Abstract
Recent investigations have meaningfully developed our knowledge of the features of the reproductive microbiome/metabolome profile and their relations with host responses to offer an optimal milieu for the development of the embryo during the peri-implantation period and throughout pregnancy. In this context, the establishment of homeostatic circumstances in the Female Reproductive Tract (FRT), in various physiological periods, is a significant challenge, which appears the application of postbiotics can facilitate the achievement of this goal. So, currently, scientific literature confirms that postbiotics due to their antimicrobial, antiviral, and immunomodulatory properties can be considered as a novel biotherapeutic approach. Future investigation in this field will shed more translational mechanistic understanding of the interaction of the postbiotics derived from vaginal Lactobacilli with females' health and reproduction.

Abstract
BACKGROUND The aim of this study was to identify vaginal Lactobacillus spp. and quantify vaginal inflammatory cytokines in primigravida vs. multigravida women and pregnant vs. non-pregnant women. METHODS Vaginal swabs were obtained from four groups of patients. A real-time PCR was carried out to identify the Lactobacillus spp. Multiplex immunoassays were performed to quantify a total of 27 cytokines using the Bio-Plex MAGPIX multiplex reader and MesoQuick Plex SQ 120 (Meso Scale Diagnostics LLC, Rockville, MD, USA). Inferential statistics using hypothesis tests were applied to detect differences in cytokine levels. RESULTS Significant differences in cytokines and chemokines exist among the four populations of women studied. IP-10 is significantly higher in multigravida women as compared to primigravida women. IFN-γ, MCP-1, MIP-1β, IL-2 and IL-10 are significantly higher in non-pregnant women compared to pregnant women. L. iners was the most abundant species in multigravida, pregnant and non-pregnant patients, while L. crispatus was the most abundant species in primigravida patients. Significant differences in the levels of MIP-1β, TNF-α, PDGF-BB, VEGF-A, IL-12, and IL-10 exist between women identified with Lactobacillus species and women not identified with Lactobacillus species. CONCLUSIONS There were significant differences regarding cytokines, chemokines, and Lactobacillus spp. among four groups of studied patients. With these results, we increase our understanding of the role that vaginal cytokines and Lactobacillus species have during pregnancy, with the goal that this novel research will be useful for examining vaginal biomarkers in obstetrical conditions.

Abstract
Strain Marseille-P5643T was isolated from a vaginal sample of a healthy Senegalese woman. It is an anaerobic Gram-negative, rod-shaped bacterium. Strain Marseille-P5643T exhibits 93.7% similarity levels with the Facklamia hominis strain ATCC 700628T, the phylogenetically closest related species with standing in nomenclature. The draft genome size of strain Marseille-P5643T is 1.79 Mb with 39.0 mol% of G+C content. We propose here the creation of Vaginisenegalia massiliensis gen. nov., sp. nov., as a new bacterial genus from the phylum Firmicutes.

Abstract
BACKGROUND In Yemen, the underlying causes of infectious vaginitis have been neglected. Therefore, this study aimed to determine the prevalence and risk factors associated with bacterial vaginosis (BV), vulvovaginal candidiasis (VVC) and trichomonal vaginitis (TV) among non-pregnant reproductive-aged women. METHODS A cross-sectional study was conducted among 347 non-pregnant reproductive-aged women seeking primary healthcare in Sana'a city, Yemen. Data about sociodemographic characteristics, lifestyle-related behaviors, routine hygienic practices, menstrual care and history and type of contraceptive intake were collected using a structured questionnaire. Vaginal discharge samples were collected and examined for discharge characteristics and pH by a gynecologist. Then, samples were examined for BV, VVC and TV. Data were analyzed using suitable statistical tests. RESULTS Vaginal infections were prevalent among 37.6% of reproductive-aged women, where BV was the most prevalent (27.2%). VVC was significantly higher among symptomatic women and significantly associated with itching (P = 0.005). Using bivariate analysis, the age of < 25 years (odds ratio [OR] = 1.9, 95% confidence interval [CI]: 1.16-3.10; P = 0.010) and using intrauterine contraceptive devices (IUCDs) (OR = 1.8, 95% CI: 1.09-2.89; P = 0.020) were significantly associated with BV, while history of miscarriage was significantly associated with a lower risk of BV (OR = 0.5, 95% CI: 0.31-0.85, P = 0.009). However, polygyny was significantly associated with VVC (OR = 3.4, 95% CI: 1.33-8.66; P = 0.007). Multivariable analysis confirmed that age of < 25 years and using IUCD were the independent predictors of BV, while history of miscarriage was an independent protective factor against BV. On the other hand, marriage to a polygamous husband was the independent predictor of VVC. CONCLUSIONS More than a third of non-pregnant reproductive-aged women seeking PHC in Sana'a have single or mixed infections with BV, VVC or TV. BV is the most frequent cause of vaginitis and is significantly associated with the age of < 25 years and using IUCDs, while VVC is significantly higher among women with polygamous husbands. Health education of polygamous husbands and their wives, regular monitoring of BV among IUCD users and screening women for vaginitis before treatment are recommended.

Abstract
The human microbiome project has shown a remarkable diversity of microbial ecology within the human body. The vaginal microbiota is unique in that in many women it is most often dominated by Lactobacillus species. However, in some women it lacks Lactobacillus spp. and is comprised of a wide array of strict and facultative anaerobes, a state that broadly correlates with increased risk for infection, disease, and poor reproductive and obstetric outcomes. Interestingly, the level of protection against infection can also vary by species and strains of Lactobacillus, and some species although dominant are not always optimal. This factors into the risk of contracting sexually transmitted infections and possibly influences the occurrence of resultant adverse reproductive outcomes such as tubal factor infertility. The composition and function of the vaginal microbiota appear to play an important role in pregnancy and fertility treatment outcomes and future research in this field will shed further translational mechanistic understanding onto the interplay of the vaginal microbiota with women's health and reproduction.
