RESUMO

Despite its devastating impact, neonatal herpes is not a nationally notifiable condition. As of 2023 it is only reportable in 6 states. A consistently applied case definition with designation as a nationally notifiable condition would optimize surveillance and preventative efforts.

RESUMO

BACKGROUND: Pre-exposure prophylaxis (PrEP), condom use, post-exposure prophylaxis (PEP), and sexual partner reduction help to prevent HIV acquisition but have low uptake among young people. We aimed to assess the efficacy of automated text messaging and monitoring, online peer support, and strengths-based telehealth coaching to improve uptake of and adherence to PrEP, condom use, and PEP among adolescents aged 12-24 years at risk of HIV acquisition in Los Angeles, CA, USA, and New Orleans, LA, USA. METHODS: We conducted a four-arm randomised controlled factorial trial, assessing interventions designed to support uptake and adherence of HIV prevention options (ie, PrEP, PEP, condom use, and sexual partner reduction). We recruited young people aged 12-24 years who were at risk of HIV acquisition from 13 community-based organisations, adolescent medicine clinics, and organisations serving people who are unstably housed, people who were previously incarcerated, and other vulnerable young people, and through dating apps, peer referrals, and social venues and events in Los Angeles, CA, USA, and New Orleans, LA, USA. Young people who tested seronegative and reported being gay, bisexual, or other men who have sex with men, transgender men or women, or gender diverse (eg. non-binary or genderqueer) were eligible for inclusion. Participants were randomly assigned to one of four intervention groups in a factorial design: automated text messaging and monitoring (AMMI) only, AMMI plus peer support via private social media, AMMI plus strengths-based telehealth coaching by near-peer paraprofessionals, or AMMI plus peer support and coaching. Assignment was further stratified by race or ethnicity and sexual orientation within each interviewer's group of participants. Participants were masked to intervention assignment until after baseline interviews when offered their randomly assigned intervention, and interviewers were masked throughout the study. Interventions were available throughout the 24-month follow-up period, and participants completed baseline and follow-up assessments, including rapid diagnostic tests for sexually transmitted infections, HIV, and substance use, at 4-month intervals over 24 months. The primary outcomes were uptake and adherence to HIV prevention options over 24 months, measured by self-reported PrEP use and adherence, consistent condom use with all partners, PEP prescription and adherence, and number of sexual partners in participants with at least one follow-up. We used Bayesian generalised linear modelling to assess changes in outcomes over time comparing the four study groups. This study is registered with ClinicalTrials.gov (NCT03134833) and is completed. FINDINGS: We screened 2314 adolescents beginning May 1, 2017, to enrol 1037 participants (45%) aged 16-24 years between May 6, 2017, and Aug 30, 2019, of whom 895 (86%) had follow-up assessments and were included in the analytical sample (313 assigned to AMMI only, 205 assigned to AMMI plus peer support, 196 assigned to AMMI plus coaching, and 181 assigned to AMMI plus peer support and coaching). Follow-up was completed on Nov 8, 2021. Participants were diverse in race and ethnicity (362 [40%] Black or African American, 257 [29%] Latinx or Hispanic, 184 [21%] White, and 53 [6%] Asian or Pacific Islander) and other sociodemographic factors. At baseline, 591 (66%) participants reported anal sex without a condom in the past 12 months. PrEP use matched that in young people nationally, with 101 (11%) participants reporting current PrEP use at baseline, increasing at 4 months to 132 (15%) and continuing to increase in the AMMI plus peer support and coaching group (odds ratio 2·31, 95% CI 1·28-4·14 vs AMMI control). There was no evidence for intervention effect on condom use, PEP use (ie, prescription or adherence), PrEP adherence, or sexual partner numbers. No unanticipated or study-related adverse events occurred. INTERPRETATION: Results are consistent with hypothesised synergistic intervention effects of evidence-based functions of informational, motivational, and reminder messaging; peer support for HIV prevention; and strengths-based, goal-focused, and problem-solving telehealth coaching delivered by near-peer paraprofessionals. These core functions could be flexibly scaled via combinations of technology platforms and front-line or telehealth HIV prevention workers.

RESUMO

BACKGROUND: Sexually transmitted infections (STIs) associated with genital ulcer disease due to herpes simplex virus-2 (HSV-2) are a prominent cause of morbidity and mortality. Serologic screening for HSV-2 is recommended only for individuals with genital herpes symptom history. However, no validated symptom screening tool currently exists. METHODS: Currently asymptomatic adults presenting for routine care at STI clinics in Lima, Peru completed a survey of prior genital herpes symptoms and received HSV-2 serological testing with the Euroimmun Anti-HSV-2 (gG2) ELISA IgG (Lubeck, Germany). A sub-sample of indeterminate results were sent for Western blot confirmatory testing. We assessed associations between past symptoms and anti-HSV-2 positivity and corrected the HSV-2 prevalence by re-classifying indeterminates per Western Blot results. RESULTS: We enrolled 131 participants between July and October 2022. HSV-2 antibody test results found 21.4% positive, 41.2% indeterminate, and 37.4% negative. Excluding indeterminate results, 36.4% were positive. Of participants with no prior symptoms 31.2% tested positive, compared to 35.7% with one prior symptom, 50.0% with 2, and 50.0% with 3+ prior symptoms. Among the sub-sample of indeterminates, 92.6% were confirmed positive by Western Blot, bringing the total estimated proportion of participants with HSV-2 antibodies to 59.5%. Either based on the original classification of HSV-2 antibody status or after incorporation of confirmatory testing results, there was no significant association between symptom history and HSV-2 antibody positivity. CONCLUSIONS: With currently available tests, recommendations to screen individuals based on genital herpes symptom history may not be useful. More discriminatory symptom screening tools or HSV-2 antibody tests with better performance are needed.

RESUMO

Gay and bisexual men in Kenya face extreme socio-political stigma which manifests in widespread violence and discrimination across socio-ecological levels. We conducted individual in-depth interviews with 60 gay and bisexual men in western and central Kenya. Interview transcripts were thematically analyzed using an inductive, phenomenological approach to qualitatively examine experiences of stigma and violence at the interpersonal and institutional levels. A total of seven primary themes and four sub-themes emerged from the data. At the interpersonal level, participants described stigma and violence from family, friends, and romantic/sexual partners with sub-themes for gay-baiting violence, blackmail, intimate partner violence, and commitment phobia. At the institutional level, participants described stigma and violence from religious, employment, educational, and healthcare institutions. This stigma and violence severely impacted the lives of participants including their mental health, physical health, sexual health, socioeconomic status, and ability to access health-promoting services. These data identify sources of stigma and describe how this stigma manifests in the everyday lives of gay and bisexual men in Kenya. Study findings and quotes from participants highlight the severity of violence, stigma, and discrimination faced by this community and emphasize the need for decriminalization of same-sex sexualities as well as interventions to support health and wellbeing.

RESUMO

BACKGROUND: Glycogen storage disease type Ib (GSD Ib) is a severe disorder of carbohydrate metabolism due to bi-allelic variants in SLC37A4. It is associated with neutropaenia and neutrophil dysfunction, which has recently been attributed to the accumulation of 1,5-anhydroglucitol-6-phosphate (1,5AG6P) within neutrophils. Treatment with sodium-glucose co-transporter-2 (SGLT2) inhibitors, such as empagliflozin, is a novel therapy that reduces 1,5-anhydroglucitol (1,5AG) in plasma. RESULTS: We report our experience in treating 8 paediatric GSD Ib patients with empagliflozin with a cumulative treatment time greater than 12 years. Treatment with a median dose of 5 mg (0.22 mg/kg height weight) of empagliflozin resulted in improvement in bowel health, growth, and laboratory parameters. Plasma 1,5AG levels reduced by a median of 78%. Baseline 1,5AG levels in our cohort were higher than in adult patients with GSD Ib. Hypoglycaemia on empagliflozin treatment occurred in 50% of our cohort. CONCLUSION: We report the largest single centre cohort of GSD Ib patients treated with empagliflozin to date. Treatment with SGLT2 inhibitors is a novel and favourable treatment option for neutropaenia and neutrophil dysfunction in GSD Ib. We suggest a low starting dose of empagliflozin with careful titration due to the risk of hypoglycaemia. The interpretation of 1,5AG levels and their role in treatment monitoring is yet to be established, and requires ongoing research.

RESUMO

Gay and bisexual men and other men who have sex with men (GBMSM) experience many sexual orientation-related stressors that negatively influence physical and mental health, making it imperative to understand their experiences of resilience-promoting resources such as social support. We utilized qualitative and participatory methodologies to examine sources of social support and types of social support received by GBMSM in Western Kenya through in-depth interviews with 60 GBMSM, including both peer educators and community members. GBMSM received emotional, informational, and instrumental support from six different relationship types: friends and peer groups, family of origin, sexual and romantic partners, healthcare providers, peer educators, and other people including work colleagues and police officers. A key finding from this study is the centrality of sexuality-specific support across all sources and types of support. Implications for clinics and LGBTQ organizations, policy, and future research are discussed.

RESUMO

Gay and bisexual male youth in Kenya experience human rights violations, including pervasive stigma and discrimination, and these oppressive forces are associated with elevated rates of mental health concerns. Despite these challenges, many gay and bisexual male youth in Kenya are thriving during this critical developmental period. This study explored intrapersonal processes that gay and bisexual male youth in Kisumu, Kenya, highlight as important to developing, and demonstrating resilience in the face of adversity. We conducted qualitative in-depth interviews (IDIs) with 40 gay and bisexual male youth, ages 20-30 (mean = 26.4), and an additional 20 IDIs with gay and bisexual men, ages 22-45 (mean = 26.6), who were working as peer educators (total n = 60), all in Kisumu, Kenya. A total of nine primary themes emerged which describe various intrapersonal resilience processes enacted by gay and bisexual male youth, including sexual identity acceptance, self-confidence, self-love, religious/spiritual affirmation, adaptive coping, successful navigation, legal rights awareness, economic stability, and advocacy satisfaction. These data demonstrate the range of positive personal processes that promote mental health and wellbeing among gay and bisexual male youth in Kenya. We discuss implications of these findings for community-based interventions, and call for a research paradigm shift away from deficits and toward resilience.

RESUMO

We are the next generation of public health practitioners. As public health students, we acknowledge that the COVID-19 (coronavirus disease 2019) pandemic will continue to fundamentally alter the field that we are preparing to enter. We will be the first wave of public health professionals whose education is being shaped by this pandemic. For decades to come, we will be working to address the impacts of this pandemic. In this commentary, we are lending our voice to discuss and highlight the importance of considering the intersections of various determinants of health and COVID-19, including education, food insecurity, housing instability, and economic hardship. We provide a discussion on what is being done across the United States in attempts to reduce the growing health inequities. As the next generation of public health leaders, we believe that only by investing in these issues can we begin to address the social and economic impact of the COVID-19 pandemic.

RESUMO

According to the egosystem-ecosystem theory of social motivation, people with ecosystem motivation believe their interpersonal relationships work in nonzero-sum ways. A longitudinal study of individuals in romantic relationships and a study of romantic couples who had a conflict discussion in the laboratory both showed that compassionate goals predict increased nonzero-sum beliefs through increased responsiveness and perceptions of partner's responsiveness and that nonzero-sum beliefs uniquely predict increased relationship quality through increased optimism that relationship problems can be overcome. The results support the view that motivational orientations shape people's lay theories that their relationship works in zero-sum or nonzero-sum ways, and further show that nonzero-sum beliefs are an important and unique predictor of change in relationship quality independent of responsiveness or perceived partner responsiveness.

RESUMO

OBJECTIVE: The associations substance use has with sex and condom use among college students appear to be well documented and of clear public health significance. However, few event-level studies examine marijuana or heavy alcohol use, control for temporal patterns shared among these behaviors, or consider differences by relationship status. METHOD: We recruited 284 18- to 22-year-old undergraduate men and women (79%), 61% of whom were in a serious relationship. For 24 consecutive days, participants reported on their prior day marijuana use, heavy alcohol use, vaginal intercourse, and condom use. RESULTS: Most intercourse events (86%) were reported by participants in a serious relationship, and most (62%) were not protected by a condom. Hierarchical generalized linear models indicated that participants in a serious relationship were more likely to report intercourse than were others. Adjusting for weekly patterns in intercourse, odds of intercourse were higher on days participants reported marijuana or heavy alcohol use; the latter effect was stronger for single participants. Being drunk during sex, being in a serious relationship, and using noncondom birth control were associated with less condom use. CONCLUSIONS: Models distinguish among multiple potential influences on undergraduates' sexual behavior. Findings suggest that greater attention to the relationship and other contexts of marijuana and alcohol use may be relevant to understanding young adults' sexual behavior and preventing health-risking or nonconsensual sex.

RESUMO

We investigated whether a "yearly" histrelin implant would provide pubertal suppression when left in place for 2 years. Equivalent suppression was observed when comparing 12 and 24 months in 33 children with central precocious puberty. A single implant for 2 years reduces cost and number of implant procedures.

RESUMO

OBJECTIVE: To investigate the use of random ultrasensitive (US) luteinizing hormone (LH) levels to monitor children being treated with a histrelin implant for central precocious puberty (CPP). STUDY DESIGN: This was a prospective, uncontrolled, observational study at a pediatric endocrinology tertiary center. Thirty-three children (26 girls; mean age 7.2 ± 2.5 years) treated with a histrelin implant for CPP were enrolled. A random US LH measurement was obtained at 6 months, and a gonadotropin-releasing hormone analog stimulation test was performed at 12 months. Clinic visits occurred at baseline and at 6-month intervals. RESULTS: In 59% of the patients (17 of 29), the 6-month random US LH exceeded the prepubertal range of ≤0.3 IU/L. In contrast, gonadotropin-releasing hormone analog stimulation tests revealed complete hypothalamic-pituitary-gonadal axis suppression (peak LH <4 IU/L) in all 31 patients who underwent testing. US LH levels were highly correlated with peak stimulated LH levels. The mean peak stimulated LH level was higher in patients with a pubertal random LH than in those with a prepubertal random LH (1.2 ± 0.5 IU/L vs 0.5 ± 0.1 IU/L; P < .01). No patient had clinical evidence of pubertal progression. CONCLUSION: The random US LH level does not revert to a prepubertal range in more than one-half of patients with a histrelin implant and documented hypothalamic-pituitary-gonadal axis suppression. Long-term studies are needed to elucidate the optimal strategy for monitoring treatment in children with CPP.

RESUMO

Testotoxicosis, a form of gonadotropin-independent precocious puberty, results from an activating mutation of the luteinizing hormone receptor expressed in testicular Leydig cells. Affected males experience early testosterone secretion, virilization, advancing bone age, and resultant short stature. Recently, the use of combination therapy with a potent antiandrogen agent (bicalutamide) and a third-generation aromatase inhibitor (anastrozole or letrozole) was reported to yield encouraging short-term results. We present here the results of longer-term treatment (4.5 and 5 years) with this combination therapy in 2 boys who demonstrated that it is well tolerated, slows bone-age advancement in the face of continued linear growth, and prevents progression of virilization.

RESUMO

In 2007, a hydrogel histrelin implant was approved for the treatment of children with central precocious puberty (CPP). Children with CPP commonly have reduced height potential due to premature closure of the epiphyseal growth plates from exposure to sex steroids. Gonadotropin-releasing hormone analog (GnRHa) treatment halts puberty and allows for improvement of adult height. A hydrogel implant delivery system utilizing the potent GnRHa, histrelin, was first developed for use in men with prostate cancer. A once yearly histrelin subcutaneous implant was subsequently developed for the treatment of children with CPP. Studies to date have demonstrated safety, tolerability, and effectiveness of this treatment option in patients treated up to 2 years. The most common adverse effects of the implant relate to implant site pain or bruising. Cost of this treatment seems comparable to somewhat higher than the commonly used GnRHa treatment option, depot leuprolide. While long term studies are needed to establish continued efficacy and safety beyond 2 years of treatment, the histrelin implant appears to be an attractive option for GnRHa treatment in patients with CPP.
