HIV self-test kits may have the potential to increase testing rates around the globe, and thereby lead to reductions in HIV-related incidence and mortality. However, the effectiveness of these ...self-test kits and the issues surrounding self-testing have been greatly debated in recent years. We conducted a literature review on the acceptability, feasibility, and effectiveness of HIV self-testing (HST) around the world. Of the 28 articles abstracted, several themes of HST were explored, including behavioral risk compensation, presence of counseling, uses of HST, ability to perform the self-test, sensitivity and specificity, concordance with confirmatory testing, perceptions surrounding HST, instruction and supervision, and cost. Overall, this literature review found that this diverse group of participants generally performed HST correctly with a few exceptions, were accepting of the test if available at a relatively low cost, and preferred the oral-based HST over the blood-based test.
COVID-19 brought enormous challenges to public health surveillance and underscored the importance of developing and maintaining robust systems for accurate surveillance. As public health data ...collection efforts expand, there is a critical need for infectious disease modeling researchers to continue to develop prospective surveillance metrics and statistical models to accommodate the modeling of large disease counts and variability. This paper evaluated different likelihoods for the disease count model and various spatiotemporal mean models for prospective surveillance.
We evaluated Bayesian spatiotemporal models, which are the foundation for model-based infectious disease surveillance metrics. Bayesian spatiotemporal mean models based on the Poisson and the negative binomial likelihoods were evaluated with the different lengths of past data usage. We compared their goodness of fit and short-term prediction performance with both simulated epidemic data and real data from the COVID-19 pandemic.
The simulation results show that the negative binomial likelihood-based models show better goodness of fit results than Poisson likelihood-based models as deemed by smaller deviance information criteria (DIC) values. However, Poisson models yield smaller mean square error (MSE) and mean absolute one-step prediction error (MAOSPE) results when we use a shorter length of the past data such as 7 and 3 time periods. Real COVID-19 data analysis of New Jersey and South Carolina shows similar results for the goodness of fit and short-term prediction results. Negative binomial-based mean models showed better performance when we used the past data of 52 time periods. Poisson-based mean models showed comparable goodness of fit performance and smaller MSE and MAOSPE results when we used the past data of 7 and 3 time periods.
We evaluate these models and provide future infectious disease outbreak modeling guidelines for Bayesian spatiotemporal analysis. Our choice of the likelihood and spatiotemporal mean models was influenced by both historical data length and variability. With a longer length of past data usage and more over-dispersed data, the negative binomial likelihood shows a better model fit than the Poisson likelihood. However, as we use a shorter length of the past data for our surveillance analysis, the difference between the Poisson and the negative binomial models becomes smaller. In this case, the Poisson likelihood shows robust posterior mean estimate and short-term prediction results.
•Adult diagnosis of epilepsy was associated with an increased risk of subsequent substance use disorder diagnosis.•A migraine diagnosis was associated with an increased risk of substance use disorder ...but not to the same extent as an epilepsy diagnosis.•Adults diagnosed with epilepsy who were uninsured or insured through Medicaid had a higher incidence of substance use disorder diagnoses.•Adults with epilepsy may benefit from mental healthcare inclusive of substance use prevention.
We investigated adult-onset epilepsy as a risk factor for the development of substance use disorder (SUD) by comparing the rate of SUD diagnosis among adults diagnosed with epilepsy with presumably healthy controls with lower extremity fractures (LEF). For additional comparison, we investigated the risk for adults with migraine only. Epilepsy and migraine are both episodic neurological disorders and migraine is frequently comorbid with epilepsy.
We conducted a time-to-event analysis using a subset of surveillance data of hospital admissions, emergency department visits, and outpatient visits in South Carolina, USA from January 1, 2000, through December 31, 2011. Individuals aged 18 years or older were identified using the International Classification of Disease, 9thRevision Clinical Modification (ICD-9) with a diagnosis of epilepsy (n = 78,547; 52.7% female, mean age 51.3 years), migraine (n = 121,155; 81.5% female, mean age 40.0 years), or LEF (n = 73,911; 55.4% female, mean age 48.7 years). Individuals with SUD diagnosis following epilepsy, migraine, or LEF were identified with ICD-9 codes. We used Cox proportional hazards regression to model the time to SUD diagnosis comparing adults diagnosed with epilepsy, migraine, and LEF, adjusting for insurance payer, age, sex, race/ethnicity, and prior mental health comorbidities.
Compared to LEF controls, adults with epilepsy were diagnosed with SUD at 2.5 times the rate HR 2.48 (2.37, 2.60) and adults with migraine only were diagnosed with SUD at 1.12 times the rate HR 1.12 (1.06, 1.18). We found an interaction between disease diagnosis and insurance payer, with hazard ratios comparing epilepsy to LEF of 4.59, 3.48, 1.97, and 1.44 within the commercial payer, uninsured, Medicaid, and Medicare strata, respectively.
Compared to presumably healthy controls, adults with epilepsy had a substantially higher hazard of SUD, while adults with migraine only showed a small, but significant, increased hazard of SUD.
In Kenya, HIV testing during first antenatal care (ANC) visit is a standard practice for pregnant women. Despite a policy promoting male partner testing in ANC, few male partners accompany their ...partners for HIV testing. We evaluated the impact of using oral HIV self-testing on HIV couples testing among ANC clients in Kenya and their male partners.
In a 3-arm randomized control study in eastern and central Kenya, consenting women attending the first ANC visit were randomized to receive: (1) standard-of-care and a standard information card; (2) an improved card stating the importance of male HIV testing; and (3) 2 oral HIV self-test kits and HIV testing information. Women completed a baseline and endline questionnaire, and consenting male partners were surveyed 3 months after enrolling female ANC clients. The primary outcome was HIV couples testing as reported by the female partners.
We randomized 1410 women at their first ANC visit of which 1215 were successfully followed up. One thousand one hundred thirty-three male partners consented to the survey. In the self-testing study arm 3, 79.1% (334/422) of the women reported that their partner tested for HIV as part of a couple, compared with 27% (110/406) and 35.1% (136/387) in study arm 1 and study arm 2, respectively. More than 90% of male partners who used the oral HIV self-test kits reported that it was easy to take sample and read the test results.
The study demonstrates that the ANC platform offers a unique opportunity to increase HIV couples testing among men using self-testing through distribution by their female partners.
While self-rated health (SRH) and quality of life (QoL) has been associated with substance use disorders (SUDs) in sex-working populations, little is known about this association in Iran. This study ...aimed to assess QoL and SRH in Iranian female sex workers (FSWs) in Tehran.
FSWs were recruited using convenience sampling methods from substance abuse treatment centers in Tehran that exclusively provided services for women. Participants completed an interviewer-administered demographic questionnaire in Persian and the Iranian version of the Short Form Health Survey (SF-36). Descriptive analyses, means and standard deviations; frequency and percentages, t-test and one-way ANOVA, and Chi-square tests were utilized to analyze the data.
The mean age among 161 participants clinically diagnosed with SUD was 34.09 years (SD 7.97; range: 18-57). The total mean QoL score was 41.03 (SD: 12.92). The highest and lowest mean scores were observed in the physical functioning (52.23) and role emotional (26.64) dimensions, respectively. Significant differences (p < 0.05) in QoL were observed according to education and marital status, and the average QoL score was lower in women who reported permanent marriages and women who were illiterate. The average score of QoL was significantly higher in employed women. Overall, 51.6% of the women rated their health as sub-optimal, with divorced participants and women who were illiterate more likely to rate their health as sub-optimal (p < 0.05).
Results emphasize the need for mental, physical, and sexual health screening and gender-specific interventions to improve QoL in this population. Further investigation may elucidate the consequences of poor SRH and QoL on SUD treatment adherence, sexual risk behavior, and morbidity and mortality in FSWs.
Providing high quality and respectful care during pregnancy and birth is one of the ways to reduce complications in women. Respectful care is a type of care that requires a valid instrument to ...measure. This study was conducted to determine the validity and reliability of the Persian version of the Respectful Maternity Care (RMC) questionnaire in 2018.
This study was performed with 150 women (in the first 48 h after birth), who were admitted in the postpartum wards of public hospitals from 1st January until 6th April 2018 in Zanjan city in Iran. Participants were selected randomly using the Poisson distribution (Time) sampling method. After receiving permission from the questionnaire's author, the internal consistency of the tool was measured by Cronbach's alpha coefficient after the Forward translation of the Persian version of the tool under expert supervision. The reliability of the modified questionnaire was assessed using a test-retest method in 10 eligible postpartum women, who completed the same questionnaire again after 72 h. The validity of the tool was confirmed by exploratory and confirmatory factor analysis using LISREL and SPSS software.
The original RMC tool achieved an overall high internal reliability (α = 0.839). Confirmatory factor analysis of original RMC scores demonstrated poor fit indices. In LISREL proposed paths for the model, one item was excluded and a re-exploratory factor analysis was performed with the remaining 14 items. Four new subscales were defined for the revised tool including Abusive Care, Effective Care, Friendly Care, and Respectful Communication, which explained 60% of the variance.
The revised tool included four subscales of Abusive Care, Effective Care, Friendly Care, and Respectful Communication in 14 items which explained 60% of the variance. Given the importance of providing high quality maternity care, and the variety of cultures and birth services across different countries, further research is needed on this RMC tool to evaluate its use in other countries and regions.
The aims were to evaluate the impact of maternal HIV infection diagnosis timing on infant outcomes. The outcomes of interest included preterm delivery (PTD) and confirmed infant HIV infection. Data ...for all HIV-exposed infants from 2004-14 were obtained. Maternal HIV infection diagnosis timing was categorized as: perinatal (PHIV), adult infection before conception, and after conception. Infant outcomes were compared according to timing of maternal HIV diagnosis. Bivariate outcomes were compared using χ
2
tests. Continuous variables were compared using Kruskal-Wallis tests. Logistic regression was used to determine predictors of PTD and infant HIV infection. Most women were diagnosed with HIV before conception: PHIV (21, 3%), before conception (431, 69%), and post-conception (176, 28%). Women diagnosed with HIV as an adult before conception were more likely to deliver preterm (P = 0.007). Prenatal care was associated with lower risk of PTD (aOR 0.1, 95% CI 0.04-0.5). Six infants contracted HIV. Infant HIV infection was more likely in women who did not take antiretroviral therapy (aOR 13.5, 95% CI 2.5-72.1) or delivered preterm (aOR 5.3, 95% 1.1-25.1). Women with PHIV were more likely to deliver at term, and there were no HIV infections among PHIV-exposed infants. These findings are reassuring to PHIV women who desire pregnancy.
HIV testing is an essential gateway to HIV prevention and treatment services. However, HIV testing uptake remains low among men due to stigma, discrimination, and confidentiality concerns. HIV ...self-testing (HIVST) is an alternative HIV testing method that can address many of these barriers for men. We conducted a systematic review to examine HIVST uptake and intervention strategies among Men in Sub-Saharan Africa.
We used a systematic approach to survey literature published from January 2010 to June 2020 using five electronic databases (PubMed-Medline, CINAHL Complete, PsychINFO, Google Scholar, and Web of Science) and a manual search. Studies were included if they were peer-reviewed, published in English, and examined HIVST willingness, uptake, and/or linkage to care and included men in Sub-Saharan Africa.
Sixty-three articles related to HIVST were reviewed. Of the included articles, 37 discussed HIVST uptake/acceptability and 24 discussed intervention strategies. Both oral swab and finger-prick methods had high acceptability with ease of access and availability of the test cited as important by men. Free HIVST kits were preferred by men. Secondary distribution of kits via peers, sexual partners, and female sex workers were successful.
HIV self-testing is highly acceptable to men. More efforts are needed to develop policies to implement HIVST programs targeting men in Sub-Saharan Africa, including a focus on linkage to care in sub-Saharan Africa. Future interventions should directly target men independently in tandem with using peers and their romantic partners to promote self-testing among men in sub-Saharan Africa. HIVST kit distribution strategies should be combined with services that can offer confirmatory tests and counseling for men as well as linkage to care.
Abstract Objective The goal of this study was to determine the prevalence of vaginitis and its association with high-risk human papillomavirus (HR HPV) in women undergoing cervical cancer screening ...in rural Tanzania. Methods For the purpose of cervical cancer screening, cytology and HR HPV polymerase chain reaction data were collected from 324 women aged between 30 and 60 years. Microscopy and gram stains were used to detect yeast and bacterial vaginosis. Cervical nucleic acid amplification test specimens were collected for the detection of Trichomonas vaginalis (TV), Chlamydia trachomatis , and Neisseria gonorrhoeae. Results The majority of women were married (320 of 324) and reported having a single sexual partner (270 of 324); the median age of participants was 41 years. HR HPV was detected in 42 participants. Forty-seven percent of women had vaginitis. Bacterial vaginosis was the most common infection (32.4%), followed by TV (10.4%), and yeast (6.8%). In multivariable logistic regression analysis, TV was associated with an increased risk of HR HPV (odds ratio, 4.2 95% CI, 1.7–10.3). Patients with TV were 6.5 times more likely to have HPV type 16 than patients negative for TV (50% vs 13.3%) (odds ratio, 6.5 95% CI, 1.1–37). Conclusions Among rural Tanzanian women who presented for cervical cancer screening, Trichomonas vaginitis was significantly associated with HR HPV infection (specifically type 16).
