RESUMO

BACKGROUND: Data on the epidemiology of sexually transmitted infections (STIs) among transgender women (TGW) with and without human immunodeficiency virus (HIV) are limited. METHODS: We analyzed baseline data collected from a cohort of adult TGW across 6 eastern and southern US cities between March 2018 and August 2020 (n = 1018). Participants completed oral HIV screening, provided self-collected rectal and urogenital specimens for chlamydia and gonorrhea testing, and provided sera specimens for syphilis testing. We assessed associations with ≥1 prevalent bacterial STI using modified Poisson regression. RESULTS: Bacterial STI prevalence was high and differed by HIV status: 32% among TGW with HIV and 11% among those without HIV (demographic-adjusted prevalence ratio = 1.91; 95% confidence interval = 1.39-2.62). Among TGW without HIV, bacterial STI prevalence differed by geographic region, race and ethnicity, and gender identity, and was positively associated with reporting >1 sexual partner, hazardous alcohol use, homelessness, having safety concerns regarding transit to health care, and no prior receipt of gender-affirming health services. Among TGW with HIV, older age was inversely associated with bacterial STI. CONCLUSIONS: TGW had a high prevalence of bacterial STIs. The prevalence and correlates of bacterial STI differed by HIV status, highlighting the unique needs and risks of TGW with and without HIV. Tailored interventions may reduce sexual health-related inequities.

RESUMO

BACKGROUND: Adults with PKU have difficulty maintaining plasma phenylalanine (Phe) in the range that is safe for neurologic function. Elevated plasma Phe is a risk factor for congenital anomalies and developmental delay in offspring resulting from pregnancies with poor Phe control in women with PKU. Enzyme supplementation with pegvaliase allows adults with PKU to eat an unrestricted diet and have plasma Phe levels in a safe range for pregnancy but pegvaliase has not been approved for use in pregnant females with PKU. We report the results of chart review of 14 living offspring of females affected with PKU who were responsive to pegvaliase and chose to remain on pegvaliase throughout their pregnancy. METHODS: Fourteen pregnancies (one triplet pregnancy) and their offspring were identified at eight PKU treatment centers and medical records from pregnancy and birth were submitted for this study. Institutional Review Board approval was obtained. Responses to a dataset were provided to a single center and analyzed. RESULTS: Six females and eight males were born without congenital anomalies and all offspring had normal growth parameters. While mothers had preexisting comorbidities, no additional comorbidities were reported in the offspring. Four of eleven infants (excluding triplet pregnancies) were delivered preterm (36%), a higher rate than the general population (12%). A single first trimester (eight weeks) miscarriage in a 40y was not counted in this cohort of 14 live born infants. CONCLUSION: This retrospective study suggests that pegvaliase is effective at maintaining safe maternal blood Phe levels during pregnancy without deleterious effects on mother or child. A tendency toward premature birth (4/11; 36%) is higher than expected.

RESUMO

Vitamin D-dependent rickets type 1A (VDDR1A) is a rare condition caused by biallelic pathogenic variants in CYP27B1, which encodes 25-hydroxyvitamin D3-1-α-hydroxylase. Inadequate activity of this enzyme results in deficient 1α-hydroxylation of inactive 25-hydroxyvitamin D to biologically active 1,25-dihydroxyvitamin D, with consequent adverse effects on calcium and phosphate metabolism. A female child was clinically diagnosed at 18 months old with hypophosphatemic rickets based on phenotype and biochemical testing, with neither parent affected. A subsequent affected male sibling led to the reconsideration of the diagnosis. Exome sequencing showed a homozygous CYP27B1 c.1040T>A (p.Ile347Asn) variant for both children. No variants were found in genes associated with hypophosphatemic rickets. A review of published cases of VDDR1A with homozygous CYP27B1 variants indicates variable clinical presentation, lack of genotype-phenotype correlation, and low serum phosphate at diagnosis in most cases. These findings emphasize the clinical importance of molecular testing as part of the diagnostic evaluation for cases of non-nutritional rickets.

RESUMO

BACKGROUND: Transgender women (TW) experience significant inequities in healthcare access and health disparities compared to cisgender populations. Access to non-transition related healthcare is understudied among TW. We aimed to assess the association between access to care and gender minority stress and resilience factors among TW living with and without HIV in eastern and southern United States. METHODS: This study was a cross-sectional analysis of baseline data drawn from a cohort of 1613 adult TW from the LITE Study. The cohort permitted participation through two modes: a site-based, technology-enhanced mode and an exclusively online (remote) mode. Exploratory and confirmatory factor analyses determined measurement models for gender minority stress, resilience, and healthcare access. Structural equation modeling was used to assess the relationships between these constructs. Models were evaluated within the overall sample and separately by mode and HIV status. RESULTS: Higher levels of gender minority stress, as measured by anticipated discrimination and non-affirmation were associated with decreased access to healthcare. Among TW living with HIV, higher levels of anticipated discrimination, non-affirmation, and social support were associated with decreased healthcare access. Among TW living without HIV in the site-based mode, resilience was positively associated with positive healthcare experiences and inversely associated with barriers to healthcare access. Among TW living without HIV in the online mode, anticipated discrimination was associated with barriers to healthcare access; resilience was positively associated with positive healthcare experiences and inversely associated with barriers to healthcare access. CONCLUSIONS: Gender minority stress was associated with increased barriers to healthcare access among TW in the US, regardless of HIV status. Resilience factors did not mediate this effect. Interventions aiming to increase healthcare access among TW can be aided by efforts to mitigate drivers of gender minority stress and improve patient experiences in healthcare facilities.

RESUMO

INTRODUCTION: Existing literature suggests that transgender women (TW) may be at high risk for adverse mental health due to stress attributed to combined experiences of stigma and complex social and structural vulnerabilities. Little research has examined how these co-occurring experiences relate to mental health. We aimed to test a theoretically driven conceptual model of relationships between stigma, social and structural vulnerabilities, and mental health to inform future intervention tailoring. DESIGN/METHODS: Partial least square path modeling followed by response-based unit segmentation was used to identify homogenous clusters in a diverse community sample of United States (US)-based TW (N = 1418; 46.2% White non-Hispanic). This approach examined associations between latent constructs of stigma (polyvictimization and discrimination), social and structural vulnerabilities (housing and food insecurity, unemployment, sex work, social support, and substance use), and mental health (post-traumatic stress and psychological distress). RESULTS: The final conceptual model defined the structural relationship between the variables of interest within stigma, vulnerability, and mental health. Six clusters were identified within this structural framework which suggests that racism, ethnicism, and geography may be related to mental health inequities among TW. CONCLUSION: Our findings around the impact of racism, ethnicism, and geography reflect the existing literature, which unfortunately shows us that little change has occurred in the last decade for TW of color in the Southern US; however, the strength of our evidence (related to sampling structure and sample size) and type of analyses (accounting for co-occurring predictors of health, i.e., stigma and complex vulnerabilities, reflecting that of real-world patients) is a novel and necessary addition to the literature. Findings suggest that health interventions designed to offset the negative effects of stigma must include anti-racist approaches with components to reduce or eliminate barriers to resources that contribute to social and structural vulnerabilities among TW. Herein we provide detailed recommendations to guide primary, secondary, and tertiary prevention efforts. CLINICAL RELEVANCE: This study demonstrated the importance of considering stigma and complex social and structural vulnerabilities during clinical care and design of mental health interventions for transgender women who are experiencing post-traumatic stress disorder and psychological distress. Specifically, interventions should take an anti-racist approach and would benefit from incorporating social support-building activities.

RESUMO

One factor potentially driving healthcare and hospital worker (HHW)'s declining mental health during the COVID-19 pandemic is feeling betrayed by institutional leaders, coworkers, and/or others' pandemic-related responses and behaviors. We investigated whether HHWs' betrayal-based moral injury was associated with greater mental distress and post-traumatic stress disorder (PTSD) symptoms related to COVID-19. We also examined if these associations varied between clinical and non-clinical staff. From July 2020 to January 2021, cross-sectional online survey data were collected from 1,066 HHWs serving COVID-19 patients in a large urban US healthcare system. We measured betrayal-based moral injury in three groups: institutional leaders, coworkers/colleagues, and people outside of healthcare. Multivariate logistic regression analyses were performed to investigate whether betrayal-based moral injury was associated with mental distress and PTSD symptoms. Approximately one-third of HHWs reported feeling betrayed by institutional leaders, and/or people outside healthcare. Clinical staff were more likely to report feelings of betrayal than non-clinical staff. For all respondents, 49.5% reported mental distress and 38.2% reported PTSD symptoms. Having any feelings of betrayal increased the odds of mental distress and PTSD symptoms by 2.9 and 3.3 times, respectively. These associations were not significantly different between clinical and non-clinical staff. As health systems seek to enhance support of HHWs, they need to carefully examine institutional structures, accountability, communication, and decision-making patterns that can result in staff feelings of betrayal. Building trust and repairing ruptures with HHWs could prevent potential mental health problems, increase retention, and reduce burnout, while likely improving patient care.

RESUMO

Transgender women who sell sex (TWSS) experience high rates of HIV acquisition. Antiretrovirals for pre-exposure prophylaxis (PrEP) represent an efficacious HIV prevention strategy. The social and structural factors affecting PrEP delivery amongst TWSS are underexplored in the literature. We conducted ethnographic research to examine how multilevel social and structural factors manifest in TWSS's lived experiences and affect PrEP delivery and use. Twenty-four transgender women were recruited from the SAPPHIRE cohort and completed interviews focused on barriers and facilitators to PrEP engagement in the context of street-based sex work. Stakeholder interviews (N = 7) were also conducted. Our findings suggest there are unique features of the risk environment that can collectively impede PrEP use among TWSS.

RESUMO

The COVID-19 pandemic has exacted a physical and mental health toll on health care and hospital workers (HHWs). To provide COVID-19 care, HHWs expected health care institutions to support equipment and resources, ensure safety for patients and providers, and advocate for employees' needs. Failure to do these acts has been defined as institutional betrayal. Using a mixed-methods approach, this study aimed to explore the experience of institutional betrayal in HHWs serving COVID-19 patients and the associations between self-reported institutional betrayal and both burnout and career choice regret. Between July 2020 and January 2021, HHWs working in an urban U.S. health care system participated in an online survey (n = 1,189) and semistructured interview (n = 67). Among 1,075 quantitative participants, 57.8% endorsed institutional betrayal. Qualitative participants described frustration when the institution did not prioritize their safety while reporting they perceived receiving inadequate compensation from the system and felt that leadership did not sufficiently respond to their needs. Participants who endorsed prolonged breaches of trust reported more burnout and stronger intent to quit their job. Quantitatively, institutional betrayal endorsement was associated with 3-fold higher odds of burnout, aOR = 2.94, 95% CI [2.22, 3.89], and 4-fold higher odds of career choice regret, aOR = 4.31, 95% CI [3.15, 5.89], compared to no endorsement. Developing strategies to prevent, address, and repair institutional betrayal in HHWs may be critical to prevent and reduce burnout and increase motivation to work during and after public health emergencies.

RESUMO

Epileptic encephalopathies (EEs) are severe brain disorders with excessive ictal (seizure) and interictal (electrographic epileptiform discharges) activity in developing brain which may result in progressive cognitive and neuropsychological deterioration. In contrast to regular epilepsy where the treatment goal is to prevent the seizure (ictal) recurrence, in patients with EE the goal is to treat both ictal as well as interictal activity to prevent further progression. With the introduction of genetic sequencing technologies over the past 20 years, there is growing recognition of the genetic basis of EE, with the majority due to monogenic causes. Monogenic etiologies of EE include pathogenic variants in the γ-aminobutyric acid type A receptor (GABA-A) encoding gene family. We present a 2-year-old patient with EE, hypotonia, and global developmental delays. Clinical trio exome sequencing showed a novel, de novo variant in GABRG1. GABRG1 encodes the γ1 subunit of the GABA-A receptor. To date, there has not been an association of EE with pathogenic variants in GABRG1. This variant is predicted to be damaging to protein structure and function, and the patient's phenotype is similar to those with pathogenic variants in other members of the GABA-A receptor encoding gene family.

RESUMO

Cisgender men who have sex with transgender women face elevated risk for HIV, yet are understudied in prevention research. We conducted in-depth interviews with 19 men who have sex with transgender women in Baltimore, Maryland and Atlanta, Georgia to explore perspectives on HIV prevention. Participants used several strategies to reduce HIV risk: condoms, frequent HIV testing, communication about HIV status with partners, and limiting the types of sex acts performed. While condom use was inconsistent, it was preferred over pre-exposure prophylaxis, in part due to medical distrust. HIV self-testing was generally viewed unfavorably. Although most participants were referred to the study by their transgender women partners, they recommended reaching other men who have sex with transgender women in bars, nightclubs, online, and through social media. HIV prevention interventions should be inclusive of the needs and experiences of men who have sex with transgender women.

RESUMO

In the United States, transgender women are disproportionately burdened by HIV infection. Research aimed at curbing the HIV epidemic for this population may benefit from innovative technology to engage participants in research. Adult transgender women (n = 41) from six cities in the southern and eastern United States participated in seven online focus groups between August 2017 and January 2018. Analyses focused on perceived acceptability of novel technologies for research purposes, particularly HIV self-testing (HIVST) and remote data collection through a mobile app. While participants noted a number of benefits to HIVST and remote study participation, including increased participant engagement and sentiments of agency, they also expressed concerns that may impact HIVST and remote participation including housing instability, inconsistent access to technology, and confidentiality. Study findings provide insight into gaps that must be addressed when using technology-enhanced methods to support HIV testing and research participation among transgender women in the US. Substantial effort is required on the part of investigators to ensure equitable access across subgroups and, thus, minimize bias to avoid reproducing health disparities in research.

RESUMO

Black and Latina transgender women (BLTW) are disproportionately impacted by HIV but remain underrepresented in HIV and health services research. Between March 2016 and May 2017, BLTW (N = 201) were recruited in Baltimore, Maryland and Washington, DC through convenience sampling for a survey assessing multilevel determinants of HIV risk and treatment outcomes. Interviews concluded with a rapid oral HIV test. Bivariate and multivariable logistic regression modeling was performed to identify gender affirmation-related correlates of self-reported HIV treatment interruptions (HIVTIs) among BLTW living with HIV who had initiated antiretroviral therapy (ART) (n = 96). Among them, 57.3% (n = 55) reported at least one HIVTI. Unmet surgical needs (aOR = 1.6), past-year marijuana use (aOR = 14.6), and no current hormone use (aOR = 24.9) were significantly (p < 0.05) associated with HIVTIs in multivariable analysis. Unmet need for gender affirmation may inhibit ART adherence, highlighting opportunities to mitigate care interruptions in alignment with community needs and goals.

RESUMO

BACKGROUND: Novel, technology-based methods are rapidly increasing in popularity across multiple facets of quantitative research. Qualitative research, however, has been slower to integrate technology into research methodology. One method, computer-mediated communication (CMC), has been utilized to a limited extent for focus group discussions. OBJECTIVE: This study aimed to assess feasibility of an online video conferencing system to further adapt CMC to facilitate synchronous focus group discussions among transgender women living in six cities in eastern and southern United States. METHODS: Between August 2017 and January 2018, focus group discussions with adult transgender women were conducted in English and Spanish by research teams based in Boston, MA, and Baltimore, MD. Participants were sampled from six cities: Baltimore, MD; Boston, MA; New York, NY; Washington, DC; Atlanta, GA; and Miami, FL. This was formative research to inform a technology-enhanced cohort study to assess HIV acquisition among transgender women. This analysis focused on the methodologic use of CMC focus groups conducted synchronously using online software that enabled video or phone discussion. Findings were based on qualitative observations of attendance and study team debriefing on topics of individual, social, technical, and logistical challenges encountered. RESULTS: A total of 41 transgender women from all six cities participated in seven online focus group discussions-five English and two Spanish. There was equal racial distribution of black/African American (14/41, 34%) and white (14/41, 34%) attendees, with 29% (12/41) identifying as Hispanic/Latina ethnicity. Overall, 29 of 70 (41%) eligible and scheduled transgender women failed to attend the focus group discussions. The most common reason for nonattendance was forgetting or having a scheduling conflict (16/29, 55%). A total of 14% (4/29) reported technical challenges associated with accessing the CMC focus group discussion. CMC focus group discussions were found to facilitate geographic diversity; allow participants to control anonymity and privacy (eg, use of pseudonyms and option to use video); ease scheduling by eliminating challenges related to travel to a data collection site; and offer flexibility to join via a variety of devices. Challenges encountered were related to overlapping conversations; variable audio quality in cases where Internet or cellular connection was poor; and distribution of incentives (eg, cash versus gift cards). As with all focus group discussions, establishment of ground rules and employing both a skilled facilitator and a notetaker who could troubleshoot technology issues were critical to the success of CMC focus group discussions. CONCLUSIONS: Synchronous CMC focus group discussions provide a secure opportunity to convene participants across geographic space with minimal time burden and without losing the standardized approach that is expected of focus group discussions. This method may provide an optimal alternative to engaging hard-to-reach participants in focus group discussions. Participants with limited technological literacy or inconsistent access to a phone and/or cellular data or service, as well as circumstances necessitating immediate cash incentives may, however, require additional support and accommodation when participating in CMC focus group discussions.

RESUMO

5q31.3 microdeletion syndrome is characterized by neonatal hypotonia, encephalopathy with or without epilepsy, and severe developmental delay, and the minimal critical deletion interval harbors three genes. We describe 11 individuals with clinical features of 5q31.3 microdeletion syndrome and de novo mutations in PURA, encoding transcriptional activator protein Pur-α, within the critical region. These data implicate causative PURA mutations responsible for the severe neurological phenotypes observed in this syndrome.

RESUMO

OBJECTIVE: To interrogate the metabolic profile of five subjects from three families with rare, nonsense and missense mutations in SLC13A5 and Early Infantile Epileptic Encephalopathies (EIEE) characterized by severe, neonatal onset seizures, psychomotor retardation and global developmental delay. METHODS: Mass spectrometry of plasma, CSF and urine was used to identify consistently dysregulated analytes in our subjects. RESULTS: Distinctive elevations of citrate and dysregulation of citric acid cycle intermediates, supporting the hypothesis that loss of SLC13A5 function alters tricarboxylic acid cycle (TCA) metabolism and may disrupt metabolic compartmentation in the brain. SIGNIFICANCE: Our results indicate that analysis of plasma citrate and other TCA analytes in SLC13A5 deficient patients define a diagnostic metabolic signature that can aid in diagnosing children with this disease.

RESUMO

Weaver syndrome is a rare condition characterized by overgrowth, macrocephaly, accelerated osseous maturation, variable intellectual disability, and characteristic facial features. Pathogenic variants in EZH2, a histone methyltransferase, have previously been identified as a cause of Weaver syndrome. However, the underlying molecular cause in many patients remains unknown. We report a patient with a clinical diagnosis of Weaver syndrome whose exome was initially non-diagnostic. Reports in the medical literature of EED associated overgrowth prompted re-analysis of the patient's original exome data. The patient was found to have a likely pathogenic variant in EED. These findings support that Weaver syndrome is a disorder with locus heterogeneity and can be due to pathogenic variants in either EZH2 or EED. This case highlights the utility of exome sequencing as a clinical diagnostic tool for novel gene discovery as well as the importance of re-examination of exome data as new information about gene-disease associations becomes available. © 2016 Wiley Periodicals, Inc.

RESUMO

Tucking is the gender-affirming practice of putting the penis and scrotum between the buttocks and moving the testes up into the inguinal canals. Our study explores tucking and health effects among transfeminine adults (n=79). Most (74.7%) had practiced tucking and among them, 67.2% had tucked ≥7 years. When tucking, the majority (84.5%) tucked daily and almost half (44.8%) ≥17 h/day. Half (50.0%) reported concern about the health effects of tucking. Itching, rash, and testicular pain were the most commonly reported health effects. Health care providers should use a harm reduction approach in addressing tucking-related concerns and supporting patients who tuck.

RESUMO

The prevalence and correlates of food insecurity-the unavailability of food and limited access to it-have not been adequately considered among transgender women (TW), particularly alongside other health-related conditions burdening this population, such as HIV infection. This study examined the prevalence and correlates of food insecurity among TW. Between 2018 and 2020, 1590 TW in the Eastern and Southern U.S. completed a multi-site baseline assessment (socio-behavioral survey and HIV testing). Descriptive statistics were calculated and multivariable Poisson models with robust error variance were used to estimate prevalence ratios and 95% confidence intervals for correlates of food insecurity (dichotomized as sometimes-to-always vs. seldom-to-never running out of food). Eighteen percent of TW were living with HIV and nearly half of participants (44%) reported food insecurity. Correlates of food insecurity included being Black, multiracial, or another race/ethnicity; having < college education, low income, unstable housing, and high anticipated discrimination; and a history of sex work and sexual violence (all p < 0.05). Food insecurity was highly prevalent among TW. Current programs to provide food support do not adequately meet the needs of TW. HIV pr evention and care programs may benefit from addressing food insecurity.

RESUMO

WDR44 prevents ciliogenesis initiation by regulating RAB11-dependent vesicle trafficking. Here, we describe male patients with missense and nonsense variants within the WD40 repeats (WDR) of WDR44, an X-linked gene product, who display ciliopathy-related developmental phenotypes that we can model in zebrafish. The patient phenotypic spectrum includes developmental delay/intellectual disability, hypotonia, distinct craniofacial features and variable presence of brain, renal, cardiac and musculoskeletal abnormalities. We demonstrate that WDR44 variants associated with more severe disease impair ciliogenesis initiation and ciliary signaling. Because WDR44 negatively regulates ciliogenesis, it was surprising that pathogenic missense variants showed reduced abundance, which we link to misfolding of WDR autonomous repeats and degradation by the proteasome. We discover that disease severity correlates with increased RAB11 binding, which we propose drives ciliogenesis initiation dysregulation. Finally, we discover interdomain interactions between the WDR and NH2-terminal region that contains the RAB11 binding domain (RBD) and show patient variants disrupt this association. This study provides new insights into WDR44 WDR structure and characterizes a new syndrome that could result from impaired ciliogenesis.

RESUMO

This study characterized arrest, incarceration, and risk factors for incident incarceration among transgender women (TW) in the northeastern and southern United States. During semiannual study visits over 24 months in a multicenter cohort study, TW completed HIV testing and self-administered surveys. In total, 1571 TW completed baseline survey; 1,312 HIV-negative TW enrolled in the cohort and contributed 2134.3 person-years to the analysis. At baseline, 37% had been arrested and 21% had been incarcerated. Incident incarceration was 23.4 per 1,000 person-years (95% confidence interval [CI]: 16.9-29.9). Sex work was significantly associated with baseline and incident incarceration (p < .01). A history of incarceration at enrollment was the strongest predictor of incident incarceration (adjusted odds ratio [aOR] 6.99; 95% CI: 3.43-14.24). Living in the South (aOR 2.69, 95% CI: 1.22-5.93), income below the federal poverty level (aOR 2.65 95% CI: 3.43-14.24), and having a recent partner who had been incarcerated (aOR 2.62, 95% CI: 1.20-5.69) also increased the odds of incident incarceration in multivariable modeling. Structural interventions to reduce poverty and decriminalize sex work have the potential to reduce incarceration rates among TW.
