Abstract
Mycoplasma genitalium is an important sexually transmitted pathogen affecting both men and women. Its extremely slow growth in vitro and very demanding culture requirements necessitate the use of molecular-based diagnostic tests for its detection in clinical specimens. The recent availability of U.S. Food and Drug Administration (FDA)-cleared commercial molecular-based assays has enabled diagnostic testing to become more widely available in the United States and no longer limited to specialized reference laboratories. Advances in the knowledge of the epidemiology and clinical significance of M. genitalium as a human pathogen made possible by the availability of molecular-based testing have led to updated guidelines for diagnostic testing and treatment that have been published in various countries. This review summarizes the importance of M. genitalium as an agent of human disease, explains the necessity of obtaining a microbiological diagnosis, describes currently available diagnostic methods, and discusses how the emergence of antimicrobial resistance has complicated treatment alternatives and influenced the development of diagnostic tests for resistance detection, with an emphasis on developments over the past few years.

Abstract
This systematic review demonstrates increasing antimicrobial resistance and incomplete understanding of the bacterium’s natural history. Since Mycoplasma genitalium was identified 40 years ago, much of the epidemiology has been described, diagnostic tests have been developed and approved, and recommended treatment approaches have been identified. However, the natural history remains incompletely understood, and antimicrobial resistance has rapidly increased. This review summarizes evidence published since the US Centers for Disease Control and Prevention 2015 Sexually Transmitted Diseases Treatment Guidelines. Data on sequelae remain insufficient, macrolide resistance is common, and fluoroquinolone resistance is increasing. Potential benefits of testing and treatment include resolving symptoms, interrupting transmission, and preventing sequelae. Potential harms include cost, patient anxiety, and increasing antimicrobial resistance.

Abstract
INTRODUCTION The present study aimed to explore the involved lncRNA-miRNA-mRNA network in the cell cycle and proliferation after conventional treatments in Luminal A breast cancer patients. METHODS The candidate miRNAs (miRs), lncRNAs, and mRNAs were first taken from the Gene Expression Omnibus and TCGA databases. The lncRNA-miR-mRNA network was then constructed using the high-throughput sequencing data. The expression levels of selected targets were measured in the breast cancer and healthy samples by the Real-Time PCR technique and compared with the clinical outcomes by the Kaplan-Meier method. RESULTS Our analysis revealed a group of differentially expressed 3 lncRNAs, 9 miRs, and 14 mRNAs in breast cancer patients. A significant expression decrease of the selected tumor suppressor lncRNAs, miRs, and genes and a substantial expression increase of the selected onco-lncRNAs, oncomiRs, and oncogenes were obtained in the patients compared to the healthy group. The plasma levels of the lncRNAs, miRs, and mRNAs were more significant after the operation, chemotherapy, and radiotherapy than the pre-treatment. The Kaplan-Meier analysis indicated that the patients with a high expression of miR-21, miR-20b, IGF1R, and E2F2 and a low expression of miR-125a, PDCD4, and PTEN had exhibited a shorter overall survival rate. CONCLUSION Our results suggested that the underlying mechanisms of the lncRNA, miRs, and mRNAs and relevant signaling pathways may be considered predictive and therapeutic targets for breast cancer.

Abstract
Objective To examine associations between Mycoplasma genitalium infection during pregnancy and adverse outcomes. Methods We did a systematic review of observational studies. We searched Medline, EMBASE, the Cochrane Library and CINAHL up to 11 August 2021. Studies were included if they compared preterm birth, spontaneous abortion, premature rupture of membranes, low birth weight or perinatal death between women with and without M. genitalium. Two reviewers independently assessed articles for inclusion and extracted data. We used random-effects meta-analysis to estimate summary ORs and adjusted ORs, with 95% CIs, where appropriate. Risk of bias was assessed using established checklists. Results We identified 116 records and included 10 studies. Women with M. genitalium were more likely to experience preterm birth in univariable analyses (summary unadjusted OR 1.91, 95% CI 1.29 to 2.81, I2=0%, 7 studies). The combined adjusted OR was 2.34 (95% CI 1.17 to 4.71, I2=0%, 2 studies). For spontaneous abortion, the summary unadjusted OR was 1.00 (95% CI 0.53 to 1.89, I2=0%, 6 studies). The adjusted OR in one case–control study was 0.9 (95% CI 0.2 to 3.8). Unadjusted ORs for premature rupture of membranes were 7.62 (95% CI 0.40 to 145.86, 1 study) and for low birth weight 1.07 (95% CI 0.02 to 10.39, 1 study). For perinatal death, the unadjusted OR was 1.07 (95% CI 0.49 to 2.36) in one case–control and 38.42 (95% CI 1.45 to 1021.43) in one cohort study. These two ORs were not combined, owing to heterogeneity. The greatest risk of bias was the failure in most studies to control for confounding. Conclusion M. genitalium might be associated with an increased risk of preterm birth. Further prospective studies, with adequate control for confounding, are needed to understand the role of M. genitalium in adverse pregnancy outcomes. There is insufficient evidence to indicate routine testing and treatment of asymptomatic M. genitalium in pregnancy. PROSPERO registration number CRD42016050962.

Abstract
Currently, infections caused by Mycoplasma genitalium are ones the most common sexually transmitted infections. Their prevalence is varied from 1.3% to 15.9%. Infections caused by M.genitalium may lead to urethritis in men and a wide spectrum of diseases in women. Antibiotic resistance now is one of the most emerging problems both in the scientific and in the healthcare fields. The usage of antimicrobials inhibiting cell wall synthesis for the treatment of M.genitalium is ineffective, and resistance to macrolides and fluoroquinolones is increasing rapidly. M.genitalium infections diagnostics is complicated due to specific conditions and duration of culture methods. The usage of nucleic acid amplification techniques is the most relevant for laboratory diagnostics, and is used in existing assays. This review compiles current data on the prevalence, molecular mechanisms of pathogenesis and antibiotic resistance, as well as diagnostics methods of M.genitalium.

Abstract
Human papilloma virus (HPV) infection is the most common viral infection of the reproductive tract. HPV infection is more prevalent in pregnant than in age-matched non-pregnant women and its prevalence increases as pregnancy progresses. A number of reports evaluated the role of HPV infection in miscarriages. In the present review, we summarize the existing evidence regarding the association between HPV infection and miscarriage. It is still unclear whether HPV infection is associated with increased risk for miscarriage. Studies in the field yielded conflicting findings and their conclusions are limited by a small sample size and/or methodological limitations. On the other hand, preclinical data support a role of HPV infection in placental dysfunction. Given the high prevalence of HPV infection and the possibility that vaccination against HPV might protect against miscarriage, more studies are needed to elucidate whether this common infection is associated with increased risk for miscarriage.

Abstract
Routine screening for Chlamydia and gonococcal infection in pregnancy is not widespread, especially in low- and middle-income countries (LMICs), despite their potential adverse consequences on pregnancy outcome. We conducted a systematic literature search of three major databases to review current literature surrounding Chlamydia trachomatis and Neisseria gonorrhoeae infections in pregnancy. We discuss the epidemiology and burden of both infections, detection methods, potential adverse feto-maternal and infant outcomes and provide an overview of treatment options. A total of 67 articles met the inclusion criteria. The prevalence of C. trachomatis and N. gonorrhoeae across all trimesters ranged between 1.0%-36.8% and 0-14.2% worldwide, respectively. The most common diagnostic method is the Nucleic acid amplification test (NAAT). In pregnancy, chlamydia is associated with preterm birth, spontaneous miscarriage, stillbirth and neonatal conjunctivitis, while gonorrhoea is mainly associated with preterm birth and stillbirth. Amoxicillin, erythromycin and azithromycin showed similar efficacy in the treatment of chlamydia in pregnancy, while ceftriaxone and cefixime were effective in treating gonorrhoea in pregnancy. Being largely asymptomatic infections in women, we opine that detection strategies with locally appropriate tools should be combined with the syndromic approach in LMICs, where there is a high burden of disease.

Abstract
Viral infections are considered to be risk factors for spontaneous abortion (SA). Conflicting results have been reported on the association between Human Papillomavirus (HPV) and SA. HPV DNA was investigated in matched chorionic villi tissues and peripheral blood mononuclear cells (PBMCs) from women who experienced SA (n = 80, cases) and women who underwent a voluntary interruption of pregnancy (VI; n = 80, controls) by qualitative PCR and quantitative droplet digital PCR (ddPCR). Viral genotyping was performed using real-time PCR in HPV-positive samples. Specific IgG antibodies against HPV16 were investigated in sera from SA (n = 80) and VI (n = 80) females using indirect ELISA assays. None of the DNA samples from SA subjects was HPV-positive (0/80), whilst HPV DNA was detected in 2.5% of VI women (p > 0.05), with a mean viral DNA load of 7.12 copy/cell. VI samples (n = 2) were found to be positive for the HPV45 genotype. The ddPCR assay revealed a higher number of HPV-positive samples. HPV DNA was detected in 3.7% and 5% of SA and VI chorionic tissues, respectively, with mean viral DNA loads of 0.13 copy/cell in SA and 1.79 copy/cell in VI (p >0.05) samples. All DNA samples from the PBMCs of SA and VI females tested HPV-negative by both PCR and ddPCR. The overall prevalence of serum anti-HPV16 IgG antibodies was 37.5% in SA and 30% in VI (p > 0.05) women. For the first time, HPV DNA was detected and quantitatively analyzed using ddPCR in chorionic villi tissues and PBMCs from SA and VI women. Circulating IgG antibodies against HPV16 were detected in sera from SA and VI females. Our results suggest that HPV infection in chorionic villi may be a rare event. Accordingly, it is likely that HPV has no significant role in SA.

Abstract
PURPOSE To analyze the effect of Chlamydia trachomatis (C. trachomatis) on adverse pregnancy outcomes based on the currently available evidence. METHODS Multiple databases were comprehensively searched from the available date of inception through December 9, 2019. The effect of C. trachomatis on adverse pregnancy outcomes was assessed using pooled odds rations (ORs) and 95% confidence intervals (CIs). Egger's test was used for publication bias. RESULTS Fifty studies involving 502,141 participants were identified. C. trachomatis infection was found to be associated with preterm birth in antibody detection [OR (95% CI): 1.571 (1.112-2.220), P = 0.010] and high-quality assessment [OR (95% CI): 1.734 (1.295-2.321), P < 0.001], preterm premature rupture of membranes (PPROM) in culture detection [OR (95% CI): 4.339 (1.806-10.424), P = 0.001] and high-quality assessment [OR (95% CI): 2.822 (1.333-5.973), P = 0.007], stillbirth [OR (95% CI): 1.585 (1.219-2.062), P = 0.001], low-birthweight babies [OR (95% CI): 2.205 (1.137-4.274), P = 0.019], and babies small for gestational age [OR (95% CI): 1.193 (1.091-1.305), P < 0.001]. No publication bias was exhibited in miscarriage (P = 0.170), preterm birth (P = 0.303), PPROM (P = 0.341), stillbirth (P = 0.533), and low-birthweight babies (P = 0.535). CONCLUSIONS C. trachomatis infection during pregnancy is associated with a higher risk of preterm birth, PPROM, stillbirth, low-birthweight babies, and babies small for gestational age.

Abstract
OBJECTIVE Mycoplasma genitalium (MG) is a sexually transmitted organism associated with cervicitis and pelvic inflammatory disease in women and has been shown to increase the risk of HIV acquisition and transmission. Little is known about the prevalence and incidence of MG in pregnant women. Our study sought to evaluate the prevalence and incidence of MG infection in HIV-infected and HIV-uninfected pregnant women. METHODS We conducted a cohort study of 197 women ≥18 years receiving antenatal care in South Africa from November 2017 to February 2019. We over-recruited HIV-infected pregnant women to compare MG by HIV infection status. Self-collected vaginal swabs, performed at the first antenatal visit, third trimester and within 1 week post partum, were tested for MG using the Aptima assay (Hologic, USA). We report on the prevalence and incidence of MG and used multivariable logistic regression to describe correlates of MG and adverse pregnancy and birth outcomes (preterm delivery, miscarriage and vertical HIV transmission), adjusting for maternal age and HIV infection status. RESULTS At first antenatal visit, the median age was 29 years (IQR=24-34) and the gestational age was 19 weeks (IQR=14-23); 47% of women enrolled in the study were HIV-infected. MG prevalence was 24% (95% CI 16% to 34%, n=22) in HIV-infected and 12% (95% CI 6.8% to 20%, n=13) in HIV-uninfected pregnant women. MG incidence during pregnancy and early post partum was 4.7 infections per 100 woman-years (95% CI 1.2 to 12.9) or 3.9 per 1000 woman-months (95% CI 1.0 to 10.7). Adjusting for maternal age, HIV-infected women had over three times the odds of being infected with MG (adjusted OR=3.09, 95% CI 1.36 to 7.06). CONCLUSION We found a high prevalence and incidence of MG in pregnant women. Younger maternal age and HIV infection were associated with MG infection in pregnancy. Further research into birth outcomes of women infected with MG, including vertical transmission of HIV infection, is needed.

Abstract
BACKGROUND Cervical cancer is the most common cancer in women. High-Risk HPV types are known as the main agents involved in genital and cervical malignancies. There may be co pathogens like STIs that are involved in enhancing the susceptibility and progression to cervical neoplasia. This study was conducted to detect C. trachomatis, HSV-2 and M. genitalium using qPCR in women suffering from cervical intraepithelial neoplasia, HPV infection and non cancerous- non HPV subjects for the association of burden of genital disorders. MATERIALS AND METHODS This descriptive study was performed on 195 Liquid Based Cytology (LBCs) specimens collected from women referred to private laboratories. Fifty, 98 and 47 samples were from women with known CIN, HPV positive and non-cancerous/non-HPV, respectively. HSV-2, C. trachomatis, M. genitalium and HPV genotypes have been detected using multiplex TaqMan Real Time PCR and PCR hybridization. RESULTS A total of 148 HPV positive samples were included. HPVs 6 (35.13%), 16 (32.43%), 18 (21.62%), 11 (9.46%), 31 (9.46%), and 51 (9.46%) were the most common genotypes. Single, 2, 3, and more than 4 multiple HPV genotypes were detected in 46%, 29.7%, 14.2%, 10.1% cases, respectively. The prevalence of M. genitalium, C. trachomatis and HSV2 was 3 (1.54%), 24 (12.3%) and 1(0.5%), respectively. There were no statistically significant differences between these pathogens and cervical intraepithelial neoplasia (p≥ 0.05). CONCLUSION HR-HPV genotypes were more prevalent in genital infections and cervical cancer. It would seem early detection of dominant STI pathogens such as Chlamydia spp. gains due to effective prevention. Here, further research is needed to understand the co-infections burden of HPV genotypes with STIs in clinical manifestations.

Abstract
Chlamydia trachomatis (CT) infection is often silent and can
lead to long-term reproductive complications in women. In this study, we
determined the prevalence of CT infection and possible associations between the
presence of the infection and clinical-epidemiological variables in pregnant
women attended at the Basic Health Units of the Coari city, Amazonas, Brazil.
From July 2016 to March 2017, 164 pregnant women undergoing prenatal care were
recruited. One hundred of these women were tested for CT infection using two
types of samples: cervico-vaginal and urine. The diagnosis was confirmed by PCR
with primers specific for the omp1 gene of CT chromosomal DNA. Of the 100
pregnant women, 18 (18%) had CT infection, 8 (8%) of which were positive in both
samples, 7 (7%) only in the urine sample and 3 (3%) only in cervical-vaginal
sample. There was moderate agreement (Kappa=0.55) and no statistically
significant difference between sample types (p = 0.400). The mean age of
infected women was 21.1 years (SD = 4.6). Of the clinical-epidemiological
variables analyzed, “more than 2 partners in the last 12 months” (p = 0.022) and
gynecological complaint of “pain after intercourse” (p = 0.020) were associated
with CT infection. This study showed a high prevalence (18%) of CT infection
among pregnant women in Coari / Amazonas. Urine sampales were as good as
cervical-vaginal ones for the screening of CT infection during the prenatal
period.
