 Mycoplasma spp. and Ureaplasma spp. belong to humans’ genitourinary microbiota and sometimes are associated with infections of the genitourinary tract. The aim of this study was to evaluate the occurrence of Mycoplasma spp. and Ureaplasma spp. in genital specimens from patients of the 15th Regional de Saúde of Paraná State, Brazil, and to correlate the results with clinical and laboratory data. A retrospective cross-sectional study was conducted, based on the analysis of results of vaginal, endocervical, urine and urethral culture for mycoplasmas from patients attended in a reference laboratory, from January 2009 to December 2016. We evaluated 2,475 results of culture for mycoplasmas. A total of 50.8% patients were positive for mycoplasmas. Of these, 76.8% had positive culture exclusively for Ureaplasma spp. and 4.7% for Mycoplasma hominis. Both microorganisms were isolated in the microbiology culture of 18.5% of patients. Among the positive culture, 81.4% had significant concentrations. Bacterial vaginosis was the most common alteration observed in association with mycoplasmas. The high positivity of cultures for mycoplasmas, especially Ureaplasma spp. found in our study, highlight the presence of these microorganisms in many of the genital tract disorders that can be sexually transmitted and, consequently, should not be neglected.

Portugal has been the western European country with the highest rate of notified acquired immunodeficiency syndrome (AIDS) cases since 1999 and human immunodeficiency virus (HIV) infection cases since 2000. Nonetheless, exact information on the magnitude and trends of recently acquired infections is missing. In a cross-sectional study we aimed to determine HIV prevalence, the proportion of recently acquired infections and the incidence among patients attending a Sexually Transmitted Infections (STI) clinic and among HIV positive cases tested at the AIDS Reference Laboratory (ARL), by using the Avidity Index (AI) of antibodies to identify recent HIV-1 seroconversions. Demographic and behavioural data were collected. At the STI clinic 253 patients were enrolled, 16 were found to be HIV infected (14 HIV-1, 2 HIV-2) and a prevalence of 6.3% was obtained. Four recent HIV-1 infections were identified and the HIV-1 incidence was 3.3% per year. At the ARL, 332 newly diagnosed cases of HIV-1 infection were studied, 59 (17.8%) were recent infections and an annual incidence of 4.1% was estimated. These findings support STI clinics as key sentinel sites for recently acquired HIV infections and illustrate the viability of testing for recent HIV infections in these settings and reinforce the value of this method in the surveillance for better monitoring current trends of the HIV/AIDS epidemic in Portugal.

Sex With Men

Men who have sex with men (MSM) and purchase sex (MPS) are a sub-group potentially at high risk for acquiring and transmitting sexually transmitted infections (STIs). This is a hard-to-reach population resulting in a scarcity of studies covering the issue. This cross-sectional study aimed to assess the association between purchasing sex and high-risk behaviors related to HIV/STI transmission and appraise the STI prevalence among MSM. All MSM who attended the STI clinic in Tel Aviv between 2003 and 2010 were included. Demographics, behavioral, clinical, and laboratory data were compared between MPS and non-MPS to identify high-risk sexual behaviors and STI prevalence associated with purchasing sex. Of the first visits of 2694 MSM who attended the STI clinic during the study period, 151 (5.6%) paid for sex. MPS were more commonly older and married than non-MPS. MPS were more likely to engage in behaviors associated with high risk for HIV/STI transmission, including infrequent condom use during anal sex, substance use during sex, and selling sex themselves. MPS had a higher STI prevalence than non-MPS, although this was not statistically significant ( p = 0.05). These findings highlight the need to establish culturally tailored interventions for MPS addressing the potential risks associated with purchasing sex.

Introduction: A one of the step towards achieving TB related targets is to ensure early and quality diagnosis of TB in national laboratories. WHO recommends that all national reference laboratories in TB burden countries strive to reach accreditation by 2025, based on ISO15189:2012 quality management system standard. To identify gaps, progress and evaluated the evolution in implementation QMS we performed a formal assessment of the national TB reference laboratory of Armenia, as well as estimates the specific quality indicators of NRL activity. Methodology: This is retrospective study cross-sectional study using laboratory data from the National TB Reference Laboratory in Armenia. Quality Management System assessments was conducted twice a year, using TB SLMTA assessment checklist. The sputum rejection and culture rates for quality indicators are calculated and assessed monthly. Results: Compared to the baseline in 2016, there was a quality improvement reflecting the progress from zero to a “one star” in 2018. Areas that reached half of the target score included document and records, management review and responsibilities, evaluation and audits. Sections as “client management and customer service” and “evaluation and audits” stagnated in terms of progress. In terms of NRL performace, all indicators improved except for culture positivity in smear negative tuberculosis. Conclusion: Although a quality management system was introduced in the NRL there is now an urgent need to develop and implement an adapted roadmap for Armenia. This will be vital to hasten the much-needed pace towards accreditation.

Genital Mycoplasmas

Background: Genital Mycoplasmas play a key etiological role in several urogenital diseases among both Men and Women. Just to mention the few, they are often responsible of non-gonococcal urethritis, spontaneous abortion, preterm birth, low birth weight, infertility and perinatal mortality. Aim: The study aimed to assess the prevalence of genital infections with Mycoplasma hominis, Ureaplasma urealyticum and their co-infection, as well as the susceptibility profiles to antibiotics commonly prescribed in Dschang, Cameroon. Study Design: This was a 5-years retrospective cross-sectional study (including data from January 1, 2015 to December 31, 2019) conducted at Saint Vincent de Paul Hospital in Dschang, Cameroon. Methods: Data of 338 participants received at the Gyneco-obstetric and Internal Medicine units, properly recorded, were collected from the Hospital Microbiology Laboratory records. Results: The overall prevalence to genital Mycoplasmas was 57.4%, with 44.4% attributed to Ureaplasma urealyticum, 5.9% to Mycoplasma hominis and 7.1% to the Co-infection with the two bacteria isolates. Josamycin was the most sensitive antibiotic against Ureaplasma urealyticum (85.3%) and the co-infection (91.7%). Mycoplasma hominis isolates were more susceptible to three fluoroquinolones and tetracyclines with an equal sensitivity rate of 80.0%. Emphasis is on the increasing resistance of co-infection towards Macrolides (83.3%). Summarily, Josamycin was the antibiotic to which genital Mycoplasmas showed the lowest resistance rate (6.2%) while the highest (62.9%) was attributed to Acetylspyramycin. Conclusion: The implementation of health policies in Cameroon should optimize on mechanisms of diagnosis, proper treatment and monitoring the antibiotic resistance of commonly isolated genital Mycoplasmas, regarding their impact on reproductive health.

Estimates of Trichomonas vaginalis prevalence in pregnant women are variable with few studies in Iraq.T. vaginalis is a worldwide prevalent sexually transmitted infection,but fortunately,it is very treatable. Researchers believed that pregnancy is one of the effective factors for T. vaginalis infection in women.A cross-sectional study performed in Obstetrics and Gynecology Department at Maternity and Children Teaching Hospital in Al-Diwaniya city on two hundred female pregnant patients between the ages of 16-45 years. These females had no intercourse for 2–3 days,not using drugs (antibiotics,antiprotozoal or steroids) for the last 15 days. Vaginal discharges of any type with or without itching,burning sensation or both were their main complaints. Vaginal swabs were taken from all participating patients for direct wet mount microscopy and culture for the detection of Trichomonas vaginalis infection. The study showed that twelve out of two hundred examined pregnant women (6%) presented with T. vaginalis infection. The infection was more in those with mothers’ age (26-35) years,housewives,low education,higher parity,and of rural residents. Other maternal variables were not significantly associated with T. vaginalis infection. The study showed a prevalence of (6%) of T. vaginalis infection in pregnant female attendees. Infection was more in those with mothers ’age (26-35) years,housewives,low educational level,higher parity,and living in rural areas.

Abstract Background Recommendations for sexually transmitted infection (STI) screening vary significantly across countries. This study evaluated the prevalence of urogenital and extragenital infections with Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), and Mycoplasma genitalium (MG) in patients visiting a French STI clinic in the Indian Ocean region to determine whether current STI screening practices should be updated. Methods This cross-sectional study examined all patients who visited the STI clinic between 2014 and 2015. Triplex polymerase chain reaction screening for CT, NG, and MG was performed on urine, vaginal, pharyngeal, and anal specimens (FTD Urethritis Basic Kit, Fast Track Diagnostics, Luxembourg). Results Of the 851 patients enrolled in the study, 367 were women (367/851, 43.2%) and 484 were men (484/851, 56.0%). Overall, 826 urogenital specimens (826/851, 97.1%), 606 pharyngeal specimens (606/851, 71.2%), and 127 anal specimens (127/851, 14.9%) were taken from enrolled patients. The prevalence of urogenital CT and MG was high in women ≤25 years (19/186, 10.21%; 5/186, 2.69%) and in men who have sex with women ≤30 years (16/212, 7.54%; 5/212, 2.36%). Among patients with urogenital CT infection, 13.7% (7/51) had urethritis. All patients with urogenital MG infection were asymptomatic. Men who have sex with men had a high prevalence of pharyngeal CT (2/45, 4.44%) and NG (3/44, 6.81%) and a high prevalence of anal CT (2/27, 7.41%), NG (2/27, 7.40%), and MG (1/27, 3.70%). After excluding patients with concomitant urogenital infection, extragenital infections with at least 1 of the 3 pathogens were found in 20 swabs (20/91, 21.9%) taken from 16 patients (16/81, 19.7%), all of them asymptomatic. Conclusions Routine multisite screening for CT, NG, and MG should be performed to mitigate the transmission of STIs in high-risk sexually active populations.

ObjectivesIn the 2010s, there has been an increase in sexually transmitted infections (STI) in men who have sex with men (MSM) in Australia, and since 2015 also in urban heterosexuals. Men who have sex with both men and women (MSMW) have characteristics that may differ from both men who have sex with men only (MSMO) and heterosexual men. We aimed to compare the sexual practices and the trends in HIV/STI positivity between MSMO and MSMW.DesignRepeated cross-sectional study.SettingA sexual health centre in Melbourne, Australia.ParticipantsMSM aged 18 years and above who attended the Melbourne Sexual Health Centre for the first time between 2011 and 2018. This includes 12 795 MSMO and 1979 MSMW.Primary outcome measuresDemographic characterics, sexual practices and HIV/STI positivity.ResultsCompared with MSMW, MSMO were more likely to practice anal sex and to have condomless receptive anal sex with casual male partners, and less likely to have a current regular relationship. Over the 8-year period, there was an increase in condomless receptive anal sex with casual male partners for both groups (MSMO: from 46.2% to 63.3%, ptrend <0.001; MSMW: from 41.3% to 57.9%, ptrend=0.011). Syphilis positivity increased in MSMO (from 5.5% to 7.9%, ptrend=0.012) and MSMW (from 0.9% to 6.4%, ptrend=0.004) and HIV remained stable. Gonorrhoea increased among MSMO from 2011 to 2014 (from 6.7% to 9.6%, ptrend=0.002), and remained stable from 2015 to 2018. MSMO had higher odds of testing positive for gonorrhoea (adjusted OR (aOR) 1.36, 95% CI 1.13 to 1.64), chlamydia (aOR 1.39, 95% CI 1.16 to 1.67), syphilis (aOR 1.74, 95% CI 1.37 to 2.22) and HIV (aOR 4.60, 95% CI 2.43 to 8.70) than MSMW.ConclusionsMSMW have overall lower condomless sex and lower HIV/STI positivity. In the last years, changes in sexual practices in MSM have affected both MSMW and MSMO leading to an increased STI risk.

Abstract Background Laboratory data and computed tomography (CT) have been used during the COVID-19 pandemic, mainly to determine patient prognosis and guide clinical management. The aim of this study was to evaluate the association between CT findings and laboratory data in a cohort of COVID-19 patients. Methods This was an observational cross-sectional study including consecutive patients presenting to the Reggio Emilia (Italy) province emergency rooms for suspected COVID-19 for one month during the outbreak peak, who underwent chest CT scan and laboratory testing at presentation and resulted positive for SARS-CoV-2. Results Included were 866 patients. Total leukocytes, neutrophils, C-reactive protein (CRP), creatinine, AST, ALT and LDH increase with worsening parenchymal involvement; an increase in platelets was appreciable with the highest burden of lung involvement. A decrease in lymphocyte counts paralleled worsening parenchymal extension, along with reduced arterial oxygen partial pressure and saturation. After correcting for parenchymal extension, ground-glass opacities were associated with reduced platelets and increased procalcitonin, consolidation with increased CRP and reduced oxygen saturation. Conclusions Pulmonary lesions induced by SARS-CoV-2 infection were associated with raised inflammatory response, impaired gas exchange and end-organ damage. These data suggest that lung lesions probably exert a central role in COVID-19 pathogenesis and clinical presentation.
