Simultaneous real-time PCR detection of nine prevalent sexually transmitted infections using a predesigned double-quenched TaqMan probe panel
Full text linkSexually transmitted diseases are major causes of infertility, ectopic pregnancy, and premature birth. Here, we developed a new multiplex real-time polymerase chain reaction (PCR) assay for the simultaneous detection of nine major sexually transmitted infections (STIs) found in Vietnamese women, including Chlamydia trachomatis, Neisseria gonorrhoeae, Gardnerella vaginalis, Trichomonas vaginalis, Candida albicans, Mycoplasma hominis, Mycoplasma genitalium, and human alphaherpesviruses 1 and 2. A panel containing three tubes × three pathogens/tube was predesigned based on double-quenched TaqMan probes to increase detection sensitivity. There was no cross-reactivity among the nine STIs and other non-targeted microorganisms. Depending on each pathogen, the agreement with commercial kits, sensitivity, specificity, repeatability and reproducibility coefficient of variation (CV), and limit of detection of the developed real-time PCR assay were 99.0%–100%, 92.9%–100%, 100%, <3%, and 8–58 copies/reaction, respectively. One assay cost only 2.34 USD. Application of the assay for the detection of the nine STIs in 535 vaginal swab samples collected from women in Vietnam yielded 532 positive cases (99.44%). Among the positive samples, 37.76% had one pathogen, with G. vaginalis (33.83%) as the most prevalent; 46.36% had two pathogens, with G. vaginalis + C. albicans as the most prevalent combination (38.13%); and 11.78%, 2.99%, and 0.56% had three, four, and five pathogens, respectively. In conclusion, the developed assay represents a sensitive and cost-effective molecular diagnostic tool for the detection of major STIs in Vietnam and is a model for the development of panel detections of common STIs in other countries
Rapid point of care testing for four bacterial sexually transmitted infections using the portable isothermal loop-mediated nucleic acid amplification eazyplex platform
Full text linkPurpose:
To analyze sensitivity and specificity of the rapid point-of-care (POC) eazyplex testing platform for bacterial sexually transmitted infections (STI) among men who have sex with men (MSM).
Methods:
272 anal, urethral, and pharyngeal swabs collected from 153 MSM were tested by both the eazyplex platform and an in-house PCR or culture in the university microbiology reference laboratory.
Results:
Compared to the reference diagnostic method, the overall sensitivity/specificity of eazyplex was 88%/98% for N. gonorrhoeae, 82%/100% for C. trachomatis, 70%/ > 99% for U. urealyticum, and 85%/98% for M. hominis, respectively. Sensitivity for N. gonorrhoeae and U. urealyticum in urethral samples was 100%.
Conclusion:
With good to very good sensitivity depending on the sampling site and pathogen as well as very good specificity overall the eazyplex platform is a useful rapid diagnostic method for POC bacterial STI-testing especially for N. gonorrhoeae and C. trachomatis, allowing for almost immediate treatment initiation
Sexually transmitted infections among key populations in India: A protocol for systematic review
Full text linkBackground: Sexually transmitted infections (STIs) are one of the leading causes of health, and economic burdens in the developing world, leading to considerable morbidity, mortality, and stigma. The incidence and prevalence of the four curable STIs viz. syphilis, gonorrhoea, chlamydia, and trichomoniasis vary remarkably across different geographical locations. In India, the prevalence of four curable STI among general populations is in between 0 to 3.9 percent. However, it is assumed that STI prevalence is much higher among subpopulations practicing high-risk behaviour. Like men who have sex with men (MSM), transgender (TG), injecting drug users (IDU), and female sex workers (FSW).
Objectives: In the present circumstances, a systematic review is necessary to integrate the available data from previously published peer-reviewed articles and published reports from several competent authorities to provide the prevalence and geographical distribution of the four curable STIs among the key population of India.
Methods: All available articles will be retrieved from PubMed, Google Scholar, Cochrane database, Scopus, Science Direct, and the Global Health network using the appropriate search terms. The data will be extracted through data extraction form as per PICOS (population, intervention, comparison, outcome, study design) framework. Risk of bias and quality assessment will be performed according to the situation with the help of available conventional protocol.
Discussion: The future systematic review, generated from the present protocol, may provide evidence of the prevalence and geographical distribution of the four curable STIs among the key population of India. We hope that the findings of the future systematic review will strengthen the existing surveillance system in India, to determine the above-mention STIs prevalence among key populations in India
Development of an mhealth app to support the prevention of sexually transmitted infections among black men who have sex with men engaged in pre-exposure prophylaxis care in New Orleans, Louisiana: qualitative user-centered design study
Full text linkBackground:
Sexual health disparities exist for Black men who have sex with men (BMSM) in New Orleans, Louisiana. Rates of sexually transmitted infections (STIs) are high for both BMSM and those taking HIV pre-exposure prophylaxis (PrEP).
Objective:
In this study, we introduced an existing PrEP adherence app to new potential users—BMSM engaged in PrEP care in New Orleans—to guide app adaptation with STI prevention features and tailoring for the local context.
Methods:
Using a user-centered design, we conducted 4 focus group discussions (FGDs), with interim app adaptations from December 2020 to March 2021. During the FGDs, a video of the app, app website, and mock-ups were shown to participants. We asked about facilitators of and barriers to STI prevention in general, current app use, impressions of the existing app, new app features to potentially facilitate STI prevention, and how the app should be tailored for BMSM. We used applied qualitative thematic analysis to identify themes and needs of the population.
Results:
Overall, 4 FGDs were conducted with 24 BMSM taking PrEP. We grouped themes into 4 categories: STI prevention, current app use and preferences, preexisting features and impressions of the prep’d app, and new features and modifications for BMSM. Participants noted concern about STIs and shared that anxiety about some STIs was higher than that for others; some participants shared that since the emergence of PrEP, little thought is given to STIs. However, participants desired STI prevention strategies and suggested prevention methods to implement through the app, including access to resources, educational content, and sex diaries to follow their sexual activity. When discussing app preferences, they emphasized the need for an app to offer relevant features and be easy to use and expressed that some notifications were important to keep users engaged but that they should be limited to avoid notification fatigue. Participants thought that the current app was useful and generally liked the existing features, including the ability to communicate with providers, staff, and each other through the community forum. They had suggestions for modifications for STI prevention, such as the ability to comment on sexual encounters, and for tailoring to the local context, such as depictions of iconic sights from the area. Mental health emerged as an important need to be addressed through the app during discussion of almost all features. Participants also stressed the importance of ensuring privacy and reducing stigma through the app.
Conclusions:
A PrEP adherence app was iteratively adapted with feedback from BMSM, resulting in a new app modified for the New Orleans context and with STI prevention features. Participants gave the app a new name, PCheck, to be more discreet. Next steps will assess PCheck use and STI prevention outcomes
Validation of the 2018 FIGO staging system for predicting the prognosis of patients with stage IIIC cervical cancer
Full text linkBackground:
Risk stratification of patients with cervical cancer accompanied by positive lymph nodes (stage IIIC) (the 2018 International Federation of Gynecology and Obstetrics [FIGO] new staging system) yields a clinically heterogeneous group. In this study, we investigated the prognostic performance of the 2018 FIGO staging system for stage IIIC cervical cancer.
Methods:
The study included patients with stage III cervical cancer based on the 2018 FIGO staging system, who visited Chongqing University Cancer Hospital between January 2011 and December 2014. Kaplan-Meier curves were generated to evaluate overall survival (OS), which was compared using the log-rank test. The Cox proportional hazard regression model was used for multivariable analysis.
Results:
A total of 418 patients were eligible for analysis. The 5-year OS was 54.1% for stage IIIC1, 43.3% for stage IIIA, 40.6% for stage IIIB, and 23.1% for stage IIIC2 (P 2 than in patients with stage IIIC1pN1-2 (HR 2.753, 95% CI 1.527-4.965, P = .001).
Conclusions:
Patients with stage IIIC1 cervical cancer showed heterogeneous clinical characteristics that reflected variable prognoses, depending on the T stage and the extent of pelvic lymph node metastases
Predictors of oncologic outcome in patients receiving phase i investigational therapy for recurrent or metastatic cervical cancer
Full text linkIntroduction:
We aimed to identify clinical, pathologic, and treatment factors that are predictive of response and survival in patients with cervical cancer referred to phase I clinical trials.
Methods:
Patients with cervical cancer who received at least one dose of a phase I investigational agent at our institution between 2014 and 2022 were included. The log-rank test was used to analyze differences in progression-free survival (PFS) and overall survival (OS), and multivariable regression analysis was performed.
Results:
We included 65 patients with a median age of 41 years (range, 20–74), 3 prior therapies (range, 1–7), and 67.7% squamous carcinoma. The rate of distant metastasis at trial entry was 84.6%. The most common molecular alterations included PIK3CA (46.5%), PD-L1+ (46.2%), EPH (30.0%), and CREBBP (23.1%); 23.1% had received a prior checkpoint inhibitor. Phase I trials were for immunotherapy (58.5%) or targeted therapy (41.5%). The rate of biomarker matching was 21.5%. For all patients, median PFS was 3.6 months (95% CI, 2.0–5.2) and OS was 9.3 months (95% CI, 7.0–10.6). Factors at study entry associated with worse survival were presence of bone metastasis (PFS 1.6 vs 4.4 months: hazard ratio [HR], 2.8; p = 0.001; OS 3.8 vs 10.0 months: HR, 3.9; p < 0.0001) and absolute lymphocyte count below 1000/μL (PFS 1.8 vs 5.2 months: HR, 2.9; p = 0.0004; OS 7.0 vs 10.6 months: HR, 3.2; p = 0.0009). Factors associated only with worse OS were absolute neutrophil count above 4700/μL, hemoglobin below 10.5 g/dL, and smoking status. Grade 3+ treatment-related adverse events were seen in 16.9% of cases.
Conclusion:
Bone metastasis and absolute lymphocyte count below normal range at phase I study entry portend poor survival in patients with recurrent or metastatic cervical cancer
Cervical cancer screening service utilization and associated factors among women living with HIV receiving anti-retroviral therapy at Adama hospital medical college, Ethiopia
Full text linkIntroduction:
Cervical cancer is the second highest cause of cancer-related mortality in the world, and it is one of the top 20 causes of mortality in Ethiopia. Even though cervical cancer is more common among women living with HIV, the utilization of cervical cancer screening services remains low in Ethiopia.
Objectives:
This study aimed to assess cervical cancer screening service utilization and associated factors among women living with HIV receiving anti-retroviral therapy at Adama Hospital Medical College, Ethiopia.
Methods:
An institution-based cross-sectional study was conducted among a sample of 304 women living with HIV from 1st–30th June 2022. Data were collected using an interviewer-administered questionnaire. The data were entered into Epi info version 7 and exported to SPSS version 25 for analysis. Bi-variable logistic regression analysis was used to identify candidate variables at p < .25. Finally, multivariable logistic regression analysis was used to identify the independent predictors of cervical cancer screening service utilization at p < .05 with 95% confidence intervals.
Results:
The magnitude of cervical cancer screening service utilization was 26.9% (95% CI: 22.0, 32.6). Being a government employee (AOR: 8.09, 95% CI: 1.5, 41.19), having a family history of cervical cancer (AOR: 3.4, 95% CI: 1.02, 11.9), being aware of cervical cancer screening (AOR: 3.75, 95% CI: 2.11, 14.7), having a history of sexually transmitted infection (AOR: 3.14, 95% CI: 1.95, 10.2), and heard about cervical cancer (AOR: 2.6, 95% CI: 1.05, 6.41) were associated with cervical cancer screening service utilization.
Conclusion:
The magnitude of cervical cancer screening service utilization was low. It was associated with occupation status, family history of cervical cancer, awareness about cervical cancer screening, history of STI, and ever heard about cervical cancer. Thus, to maximize utilization, health education programs and other multidisciplinary strategies had to be implemented
Screening for cervical cancer among women in five countries in sub-saharan Africa: analysis of the role played by distance to health facility and socio-demographic factors
Full text linkBackground:
Cervical cancer significantly affects women in Sub-Saharan Africa (SSA). However, limited studies have concentrated on cervical screening behaviour among women in SSA. This study aimed to assess the interplay of distance to health facilities and socio-demographic factors with cervical screening behaviour among women in five SSA countries.
Methods:
The study was based on pooled data of 40,555 women included in Demographic and Health Surveys (DHS) conducted between 2013 to 2021. Proportions and logistic regression models were used in assessing the interplay of distance to health facilities and socio-demographic factors with cervical screening behaviour.
Results:
Approximately, 7.9% of women that saw the distance to a health facility as a big problem, tested for cervical cancer compared to 13.5% who indicated that distance to a health facility is not a big problem. More women in urban areas, with a higher level of education, of richest wealth index, aged 40–44 years and using contraceptives who also indicated that distance to a health facility was a big problem tested for cervical cancer compared to those in rural areas with no education, of poorest wealth index, aged 15–19 years and not using contraceptives. Education, age, contraceptive use, frequent exposure to mass media and Sexual Transmitted Infections (STI) had a significant relationship with testing for cervical cancer.
Conclusion:
The prevalence of cervical cancer screening was low in the five SSA countries largely due to distance barriers and was also significantly influenced by education, age, contraceptive use, frequent exposure to mass media, and STI status. To improve the screening for cervical cancer and its associated benefits in the five SSA countries, there is a need for policymakers, clinicians and public health workers to channel more commitment and efforts to addressing the barriers identified in this study
Research gaps and needs to optimize the use of assisted vaginal birth: technical brief
Full text linkSelf-reported sexually transmitted infections among adolescent girls and young women in Mali: analysis of prevalence and predictors
Full text linkObjective:
To examine the prevalence and predictors of self-reported sexually transmitted infections (SR-STIs) among adolescent girls and young women in Mali.
Design:
We performed a cross-sectional analysis of data from the Demographic and Health Survey of Mali, which was conducted in 2018. A weighted sample of 2105 adolescent girls and young women aged 15–24 was included. Percentages were used to summarise the results of the prevalence of SR-STIs. We used a multilevel binary logistic regression analysis to examine the predictors of SR-STIs. The results were presented using an adjusted odds ratio (aOR) with 95% confidence interval (CI). Statistical significance was set at p<0.05.
Setting:
Mali.
Participants:
Adolescent girls (15–19 years) and young women (20–24 years).
Outcome measure:
SR-STIs.
Results:
The prevalence of SR-STIs among the adolescent girls and young women was 14.1% (95% CI=12.3 to 16.2). Adolescent girls and young women who had ever tested for HIV, those with one parity, those with multiparity, those with two or more sexual partners, those residing in urban areas, and those exposed to mass media were more likely to self-report STIs. However, those residing in Sikasso and Kidal regions were less likely to report STIs.
Conclusion:
Our study has shown that SR-STIs are prevalent among adolescent girls and young women in Mali. Health authorities in Mali and other stakeholders should formulate and implement policies and programmes that increase health education among adolescent girls and young women and encourage free and easy access to STI prevention and treatment services
