Perspectives on a peer-driven intervention to promote pre-exposure prophylaxis (PrEP) uptake among men who have sex with men in southern New England: a qualitative study.

BACKGROUND: Pre-exposure prophylaxis (PrEP) is a highly effective pharmaceutical intervention that prevents HIV infection, but PrEP uptake across the US has been slow among men who have sex with men (MSM), especially among Black/African American (B/AA) and Hispanic /Latino (H/L) MSM. This study investigates the acceptability and essential components of a peer-driven intervention (PDI) for promoting PrEP uptake among MSM, with a specific focus on B/AA and H/L communities. METHODS: We conducted 28 semi-structured, qualitative interviews with MSM in southern New England to explore the components of a PDI, including attitudes, content, and effective communication methods. A purposive sampling strategy was used to recruit diverse participants who reflect the communities with the highest burden of HIV infection. RESULTS: Of 28 study participants, the median age was 28 years (interquartile range [IQR]: 25, 35). The sample comprised B/AA (39%, n = 11) and H/L (50%, n = 14) individuals. Notably, nearly half of the participants (46%) were current PrEP users. We found that many participants were in favor of using a PDI approach for promoting PrEP. Additionally, several participants showed interest in becoming peer educators themselves. They emphasized the need for strong communication skills to effectively teach others about PrEP. Moreover, participants noted that peer education should cover key topics like how PrEP works, how effective it is, and any possible side effects. CONCLUSIONS: Our study shows that effective PDIs, facilitated by well-trained peers knowledgeable about PrEP, could enhance PrEP uptake among MSM, addressing health disparities and potentially reducing HIV transmission in B/AA and H/L communities.

Adult Familial Influences on Rural Native Hawaiian and Pacific Islander Youths' E-Cigarette Use.

Background: Over the past decade, youth e-cigarette use has grown into a national epidemic, with Native Hawaiian and Pacific Islander (NHPI) youths' rates among some of the highest in the nation. Family factors significantly contribute to NHPI youths' decisions to engage in or resist substance use, yet few studies have specifically examined familial influences on NHPI youths' substance use decision-making and behaviors. Objective: The objective of this study is to examine adult familial influences on rural NHPI youths' decisions to engage in e-cigarette use. Method: Seventeen gender-specific focus groups with NHPI youths (N = 69) from eight public schools on Hawai'i Island were conducted. Results: Two family-related themes emerged from the data: 1) parental substance use permissiveness, and 2) family normalization of e-cigarette use. Conclusions: Examining adult familial contributors to NHPI youths' e-cigarette use needs to be part of a comprehensive effort to address NHPI health and substance use disparities. Prevention interventions should be explicit in addressing the family and relational context of NHPI youths' substance use.

Adverse Pregnancy Outcomes in Solid Organ Transplant Recipients: A Systematic Review and Meta-Analysis.

Importance: Transplant recipients experience high rates of adverse pregnancy outcomes; however, contemporary estimates of the association between solid organ transplantation and adverse pregnancy outcomes are lacking. Objective: To evaluate the association between solid organ transplantation and adverse pregnancy outcomes and to quantify the incidence of allograft rejection and allograft loss during pregnancy. Data Sources: PubMed/MEDLINE, EMBASE and Scopus databases were searched from January 1, 2000, to June 20, 2024, and reference lists were manually reviewed. Study Selection: Cohort and case-control studies that reported at least 1 adverse pregnancy outcome in pregnant women with solid organ transplantation vs without solid organ transplant or studies that reported allograft outcomes in pregnant women with solid organ transplantation were included following independent dual review of abstracts and full-text articles. Data Extraction and Synthesis: Two investigators abstracted data and independently appraised risk of bias using the Newcastle Ottawa Scale. A random-effects model was used to calculate overall pooled estimates using the DerSimonian-Laird estimator. Reporting followed the Meta-analysis of Observational Studies in Epidemiology (MOOSE) reporting guideline. Main Outcomes and Measures: Primary pregnancy outcomes were preeclampsia, preterm birth (<37 weeks), and low birth weight (<2500 g). Secondary pregnancy outcomes were live birth rate, gestation, very preterm birth (<32 weeks), very low birth weight (<1500 g), and cesarean delivery. Allograft outcomes were allograft loss and rejection during pregnancy. Results: Data from 22 studies and 93 565 343 pregnancies (4786 pregnancies in solid organ transplant recipients) were included; 14 studies reported adverse pregnancy outcomes, and 13 studies provided data for allograft outcomes. Pregnancies in organ transplant recipients were associated with significantly increased risk of preeclampsia (adjusted odds ratio [aOR], 5.83 [95% CI, 3.45-9.87]; I2 = 77.4%), preterm birth (aOR, 6.65 [95% CI, 4.09-12.83]; I2 = 81.8%), and low birth weight (aOR, 6.51 [95% CI, 2.85-14.88]; I2 = 90.6%). The incidence of acute allograft rejection was 2.39% (95% CI, 1.20%-3.96%; I2 = 68.5%), and the incidence of allograft loss during pregnancy was 1.55% (95% CI, 0.05%-4.44%; I2 = 69.2%). Conclusions and Relevance: In this systematic review and meta-analysis, pregnancies in recipients of a solid organ transplant were associated with a 4 to 6 times increased risk of preeclampsia, preterm birth, and low birth weight during pregnancy. There was a low overall risk of graft rejection or loss during pregnancy.

Using Expert Participation to Evaluate the Accuracy of Hand-Drawn Water-Table Maps.

Water-table maps are fundamental to hydrogeological studies and a manual, hand-drawn method is still commonly used to produce them. Despite this, the accuracy and variability of such maps have received little attention in international literature. In a unique experiment, 63 groundwater professionals drew water-table equipotential contours based on the same dataset of point measurements and were asked to infer flow directions and predict groundwater elevations at predefined locations. The root mean squared error (RMSE) for the average map calibration data was 10.5 m, which is accuracy comparable to numerical groundwater models. This study confirmed that to produce hand-drawn water-table maps, practitioners seek to not only fit the spatial data, but also to conform to their own cognitive model of hydrogeological concepts and processes. The calibration accuracy increased with experience; from a RMSE of 13.3 m for practitioners with 0-3 years of experience to a RMSE of 9.2 m for those with four or more years. Despite considerable variability in the style of the hand-drawn water-table maps, the maps were consistent in their representation of the dominant regional groundwater flow directions. There was less consensus, however, in predicting the direction of surface water-groundwater interaction for a stream reach. Hand-drawn water-table mapping remains useful and valid, especially as a starting point for hydrogeological conceptualization, yet further work is required to resolve issues around transparency, repeatability, and reproducibility.

Ku Like Kakou: Utilizing a Community-led Model of Collaboration to Respond to the COVID-19 Pandemic.

The outbreak of COVID-19 in 2020 brought significant challenges for Native Hawaiians (NH), Pacific Islanders (PI), and other communities of color worldwide. Rapidly increasing rates of infection and transmission of the virus in Native Hawaiian and Pacific Islander (NHPI) communities and incomplete or unavailable data signaled to Hawai'i's leaders that advocacy and action needed to take place to minimize the impact of COVID-19. The Native Hawaiian and Pacific Islander Response, Recovery, and Resilience team (NHPI 3R Team) emerged from an effort to lead and fill gaps in response to COVID-19. Through the swift, intentional, and collaborative work of the team and its partners, NHPI communities and the entities that serve them were better equipped to navigate the pandemic, improve health outcomes, and contribute to a reduction in the number of infections, a rise in vaccination uptake, and an increase in NH and PI representation on various levels of government agencies. As the world shifts its focus from COVID-19 to broader health topics, the NHPI 3R Team will continue to serve as a hub for the exchange of resources and a model of community-led work that can be used to tackle issues like COVID-19 and beyond.

Examining implementation determinants of a culturally grounded, school-based prevention curriculum in rural Hawai'i: A test development and validation study.

Background: This study examined the implementation determinants of a culturally grounded, school-based drug prevention curriculum in rural Hawai'i. Test development and validation procedures were used to examine the impact of implementation barriers and facilitators of the curriculum in public or charter middle/intermediate schools on Hawai'i Island. Method: A five-phase, mixed-methods approach toward test development and validation was used. These phases included item generation (Phase 1), item refinement and selection (Phase 2), item reduction (Phase 3), reliability testing (Phase 4), and validity testing (Phase 5). Educational administrators, teachers, and staff employed by the Hawai'i State Department of Education (HIDOE) participated in the study. Results: Phases 1 and 2 yielded 50 implementation barriers and 27 implementation facilitators that were evaluated by 204 HIDOE administrators, teachers, and staff. Factor analysis of the barrier items indicated a four-factor solution: (1) Innovation Barriers, (2) HIDOE State-Level Barriers, (3) Teacher-Level Barriers, and (4) Administrator-Level Barriers. Mean comparisons indicated that several barrier and facilitator items differentiated teachers from administrators in the sample. Conclusions: This study contributes to the implementation measurement literature, specifically in the areas of mental health and substance use. It also highlights the importance of addressing multiple contextual levels in the implementation of culturally focused prevention interventions. Plain Language Summary Title: Examining Implementation Barriers and Facilitators for School-Based Prevention in Hawai'i. Plain Language Summary Compared with other major ethnic groups, Native Hawaiian and Pacific Islander (NHPI) youth have substantially higher rates of substance use and higher adverse mental and physical health effects related to their use. Despite these disparities, educational and community-based practitioners have long struggled with implementing and sustaining promising substance use interventions for NHPI youth. This study contributes to our understanding of measuring implementation barriers and facilitators for substance use prevention for NHPI youth in rural school settings. It contributes to the field of health disparities and health equity promotion, by addressing calls for research to understand factors affecting successful implementation of prevention programs. This is critical toward achieving health equity for underrepresented and vulnerable populations, such as NHPI and rural youth.

A psychometric analysis of the adapted historical loss scale and historical loss associated symptoms scale among native Hawaiian adults.

Objectives: The Historical Loss Scale (HLS) and Historical Loss Associated Symptoms Scale (HLASS) are standardized measures that have been accepted and previously validated among North American Indigenous communities and allow researchers to measure the impact of Historical Loss. Evidence of the psychometric properties of this instrument have not been assessed for Native Hawaiians, the Indigenous peoples of Hawai'i. The purpose of this study is to investigate the psychometric properties of the adapted HLS (aHLS) and HLASS for adults from multiple Hawaiian Homestead Communities throughout Hawai'i. Methods: Data are based on cross-sectional surveys administered between 2014 and 2020. The final sample included 491 Native Hawaiian adults who were predominantly female (67.3%) and between the ages of 18-90 years, who were part of the larger study entitled the Hawaiian Homestead Health Survey. Factor analyses were conducted to determine the final model structures of each scale. Reliability and correlation matrices of items are also reported. Results: The final factor structure of the aHLS model suggested 3 factors: (1) General loss of culture or cultural loss, (2) Intergenerational loss, and (3) Distrust and destruction of traditional foods. The final HLASS model also suggested 3 factors: (1) Depression and Anger, (2) Shame and Anxiety, and (3) Re-experiencing, fear, and avoidance. Conclusion: These findings have implications for future research, practice, and education that explores the role of Historical Loss and associated symptoms in Native Hawaiians and Indigenous communities at large. In particular, measuring historical loss and associated symptoms in Hawaiian Homestead communities paves the way for quantitative assessments of historical trauma and healing in these communities.

Exploring Native Hawaiian and Pacific Islander Youths' E-Cigarette Resistance Strategies: Implications for Tobacco Product Use Prevention.

This study examined the e-cigarette and vaping resistance strategies used by Native Hawaiian and Pacific Islander (NHPI) youths in rural Hawai'i. Focus groups (N = 17) were conducted in eight geographically dispersed elementary, middle/intermediate, and multilevel schools in low-income communities on Hawai'i Island. Sixty-nine youths (67% NHPI, Mage = 12.5 years) participated in this study. The resistance strategies discussed across the greatest number of groups were "refuse" (saying no), "explain" (providing reasons for vaping refusal), "avoid" (avoiding people or places where e-cigarettes were used), and "leave" (walking away from a situation where e-cigarettes were being used). Participants described the challenges in using these strategies within contexts characterized by widespread peer and family vaping and strong social demands to use e-cigarettes. The findings suggest the need for multi-level interventions based on youths' resistance strategies to meaningfully reduce youth vaping use in rural and/or NHPI communities.

Comparing the effectiveness and cost-effectiveness of text-message reminders and telephone patient navigation to improve the uptake of faecal immunochemical test screening among non-responders in London: a randomised controlled trial protocol.

INTRODUCTION: Participation in bowel cancer screening is lower in regions where there is high ethnic diversity and/or socioeconomic deprivation. Interventions, such as text message reminders and patient navigation (PN), have the potential to increase participation in these areas. As such, there is interest in the comparative effectiveness of these interventions to increase bowel cancer screening participation, as well as their relative cost-effectiveness. METHODS AND ANALYSIS: This study will use a three-arm randomised controlled trial design to compare the effectiveness and cost-effectiveness of text message reminders and PN to increase the uptake of bowel cancer screening in London. Participants will be individuals who have not returned a completed faecal immunochemical test kit within 13 weeks of receiving a routine invitation from the London bowel cancer screening hub. Participants will be randomised (in a 1:1:1 ratio) to receive either (1) usual care (ie, 'no intervention'), (2) a text message reminder at 13 weeks, followed by repeated text message reminders at 15, 17 and 19 weeks (in the event of non-response) or (3) a text message reminder at 13 weeks, followed by PN telephone calls at 15, 17 and 19 weeks in the event of non-response. The primary endpoint will be participation in bowel cancer screening, defined as 'the return of a completed kit by week 24'. Statistical analysis will use multivariate logistic regression and will incorporate pairwise comparisons of all three groups, adjusted for multiple testing. ETHICS AND DISSEMINATION: Approvals to conduct the research have been obtained from University College London's Joint Research Office (Ref: 150666), the Screening Research, Innovation and Development Advisory Committee ('RIDAC', Ref: 2223 014 BCSP Kerrison), the Health Research Authority (Ref: 22/WM/0212) and the Confidentiality Advisory Group (Ref: 22/CAG/0140). Results will be conveyed to stakeholders, notably those managing the screening programme and published in peer-reviewed journals/presented at academic conferences. TRIAL REGISTRATION NUMBER: ISRCTN17245519.

The soluble (pro)renin receptor promotes a preeclampsia-like phenotype both in vitro and in vivo.

Preeclampsia is classified as new-onset hypertension coupled with gross endothelial dysfunction. Placental (pro)renin receptor ((P)RR) and plasma soluble (P)RR (s(P)RR) are elevated in patients with preeclampsia. Thus, we aimed to interrogate the role (P)RR may play in the pathogenesis of preeclampsia. Human uterine microvascular endothelial cells (HUtMECs, n = 4) were cultured with either; vehicle (PBS), 25-100 nM recombinant s(P)RR, or 10 ng/ml TNF-a (positive control) for 24 h. Conditioned media and cells were assessed for endothelial dysfunction markers via qPCR, ELISA, and immunoblot. Angiogenic capacity was assessed through tube formation and adhesion assays. Additionally, pregnant rats were injected with an adenovirus overexpressing s(P)RR from mid-pregnancy (day 8.5), until term (n = 6-7 dams/treatment). Maternal and fetal tissues were assessed. HUtMECs treated with recombinant s(P)RR displayed increased expression of endothelial dysfunction makers including vascular cell adhesion molecule-1, intracellular adhesion molecule-1, and endothelin-1 mRNA expression (P = 0.003, P = 0.001, P = 0.009, respectively), along with elevated endothelin-1 protein secretion (P < 0.001) compared with controls. Recombinant s(P)RR impaired angiogenic capacity decreasing the number of branches, total branch length, and mesh area (P < 0.001, P = 0.004, and P = 0.009, respectively), while also increasing vascular adhesion (P = 0.032). +ADV rats exhibited increased systolic (P = 0.001), diastolic (P = 0.010), and mean arterial pressures (P = 0.012), compared with -ADV pregnancies. Renal arteries from +ADV-treated rats had decreased sensitivity to acetylcholine-induced relaxation (P = 0.030), compared with -ADV pregnancies. Our data show that treatment with s(P)RR caused hypertension and growth restriction in vivo and caused marked endothelial dysfunction in vitro. These findings demonstrate the significant adverse actions of s(P)RR on vascular dysfunction that is characteristic of the preeclamptic phenotype.

Estrogenic endocrine disruptor exposure directly impacts erectile function.

Erectile dysfunction (ED) is an extremely prevalent condition which significantly impacts quality of life. The rapid increase of ED in recent decades suggests the existence of unidentified environmental risk factors contributing to this condition. Endocrine Disrupting Chemicals (EDCs) are one likely candidate, given that development and function of the erectile tissues are hormonally dependent. We use the estrogenic-EDC diethylstilbestrol (DES) to model how widespread estrogenic-EDC exposure may impact erectile function in humans. Here we show that male mice chronically exposed to DES exhibit abnormal contractility of the erectile tissue, indicative of ED. The treatment did not affect systemic testosterone production yet significantly increased estrogen receptor α (Esr1) expression in the primary erectile tissue, suggesting EDCs directly impact erectile function. In response, we isolated the erectile tissue from mice and briefly incubated them with the estrogenic-EDCs DES or genistein (a phytoestrogen). These acute-direct exposures similarly caused a significant reduction in erectile tissue contractility, again indicative of ED. Overall, these findings demonstrate a direct link between estrogenic EDCs and erectile dysfunction and show that both chronic and acute estrogenic exposures are likely risk factors for this condition.

Primary Care Providers' Experiences Treating Opioid Use Disorder Using Telehealth in the Height of the COVID-19 Pandemic.

BACKGROUND: The COVID-19 pandemic catalyzed a rapid shift in healthcare delivery towards telehealth services, impacting patient care, including opioid use disorder (OUD) treatment. Regulatory changes eliminated the in-person evaluation requirement for buprenorphine treatment, encouraging adoption of telehealth. This study focused on understanding experiences of primary care providers in predominantly rural areas who used telehealth for OUD treatment during the pandemic. METHODS: Semi-structured interviews were conducted with 22 primary care providers. Participants practiced in 13 rural and 9 urban counties in Kentucky and Arkansas. Data were analyzed using conventional content analysis. RESULTS: The pandemic significantly impacted healthcare delivery. While telehealth was integrated for behavioral health counseling, in-person visits remained crucial, especially for urine drug screenings. Telehealth experiences varied, with some facing technology issues, while others found it efficient. Telehealth proved valuable for behavioral health counseling and sustaining relationships with established patients. Patients with OUD faced unique challenges, including housing, internet, transportation, and counseling needs. Stigma surrounding OUD affected clinical relationships. Building strong patient-provider relationships emerged as a central theme, emphasizing the value of face-to-face interactions. Regarding buprenorphine training, most found waiver training helpful but lacked formal education. CONCLUSION: This research offers vital guidance for improving OUD treatment services, especially in rural areas during crises like the COVID-19 pandemic. It highlights telehealth's value as a tool while acknowledging its limitations. The study underscores the significance of strong patient-provider relationships, the importance of reducing stigma, and the potential for training programs to elevate quality of care in OUD treatment.

CO-Sprout-A Pilot Double-Blinded Placebo-Controlled Randomised Trial of Broccoli Sprout Powder Supplementation for Pregnant Women with COVID-19 on the Duration of COVID-19-Associated Symptoms: Study Protocol.

Since its discovery in late 2019, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been estimated to be responsible for at least 769.3 million infections and over 6.95 million deaths. Despite significant global vaccination efforts, there are limited therapies that are considered safe and effective for use in the management of COVID-19 during pregnancy despite the common knowledge that pregnant patients have a much higher risk of adverse outcomes. A bioactive compound found in broccoli sprout-sulforaphane-is a potent inducer of phase-II detoxification enzymes promoting a series of potentially beneficial effects notably as an antioxidant, anti-inflammatory, and anti-viral. A pilot, double-blinded, placebo-controlled randomised trial is to be conducted in Melbourne, Australia, across both public and private hospital sectors. We will assess a commercially available broccoli sprout extract in pregnant women between 20+0 and 36+0 weeks gestation with SARS-CoV-2 infection to investigate (i) the duration of COVID-19 associated symptoms, (ii) maternal and neonatal outcomes, and (iii) biomarkers of infection and inflammation. We plan to enrol 60 outpatient women with COVID-19 irrespective of vaccination status diagnosed by PCR swab or RAT (rapid antigen test) within five days and randomised to 14 days of oral broccoli sprout extract (42 mg of sulforaphane daily) or identical microcrystalline cellulose placebo. The primary outcome of this pilot trial will be to assess the feasibility of conducting a larger trial investigating the duration (days) of COVID-19-associated symptoms using a broccoli sprout supplement for COVID-19-affected pregnancies. Pregnant patients remain an at-risk group for severe disease following infection with SARS-CoV-2 and currently unclear consequences for the offspring. Therefore, this study will assess feasibility of using a broccoli sprout supplement, whilst providing important safety data for the use of sulforaphane in pregnancy.

Communication strategies and effectiveness of early childhood obesity-related prevention programs for linguistically diverse communities: A rapid review.

Children from culturally and linguistically diverse backgrounds experience higher rates of obesity and have poorer outcomes in obesity prevention studies. Interventions tailored to specific cultural groups may be limited within linguistically diverse, multicultural communities, and thus, alternative approaches to childhood obesity prevention in these communities are needed. This study aims to describe communication strategies used in interventions targeting prevention of obesity/obesity-related behaviors, among children 0-5 years, from linguistically diverse communities, and assess their effectiveness. A rapid review was conducted by systematically searching Medline, Embase, and CINAHL. The inclusion criteria are as follows: Studies reported an intervention tailored to linguistically diverse communities targeting at least one obesity-related behavior among children 0-5 years. The exclusion criteria are as follows: Interventions used simple language translations, targeted one language group, or treated obesity. A total of 4677 articles were identified with 14 studies meeting inclusion criteria. Key communication strategies included materials in multiple languages, English text written at a set readability level, and multimodal delivery. Six studies reported effectiveness data, of which five had effective primary or secondary outcomes. This is the first rapid review to identify communication strategies used in childhood obesity prevention interventions for linguistically diverse communities, highlighting a need for future research to incorporate and evaluate the communication strategies identified.

Preeclampsia to COVID-19: A journey towards improved placental and vascular function using sulforaphane.

Excess inflammation and oxidative stress are common themes in many pathologies of pregnancy including preeclampsia and more recently severe COVID-19. The risk of preeclampsia increases following maternal infection with COVID-19, potentially relating to significant overlap in pathophysiology with endothelial, vascular and immunological dysfunction common to both. Identifying a therapy which addresses these injurious processes and stabilises the endothelial and vascular maternal system would help address the significant global burden of maternal and neonatal morbidity and mortality they cause. Sulforaphane is a naturally occurring phytonutrient found most densely within cruciferous vegetables. It has anti-inflammatory, antioxidant and immune modulating properties via upregulation of phase-II detoxification enzymes. This review will cover the common pathways shared by COVID-19 and preeclampsia and offer a potential therapeutic target via nuclear factor erythroid 2-related factor upregulation in the form of sulforaphane.

Development, validation, and results of a national endoscopy safety attitudes questionnaire (Endo-SAQ).

Background and study aims Safety attitudes are linked to patient outcomes. The Joint Advisory Group on Gastrointestinal Endoscopy (JAG) identifies the need to improve our understanding of safety culture in endoscopy. We describe the development and validation of the Endo-SAQ (endoscopy safety attitudes questionnaire) and the results of a national survey of staff attitudes. Methods Questions from the original SAQ were adapted to reflect endoscopy-specific content. This was refined by an expert group, followed by a pilot study to assess acceptability. The refined Endo-SAQ (comprising 35 questions across six domains) was disseminated to endoscopy staff across the UK and Ireland. Outcomes were domain scores and the percentage of positive responses (score ≥75/100) per domain. Descriptive and comparative analyses were performed. Binary logistic regression identified staff and service factors associated with positive scores. Validity and reliability of Endo-SAQ were assessed through psychometric analysis. Results After expert review, four questions in the preliminary Endo-SAQ were adjusted. Sixty-one participants undertook the pilot study with good acceptability. A total of 453 participants completed the refined Endo-SAQ. There were positive responses in teamwork, safety climate, job satisfaction, and working conditions domains. Endoscopists had significantly more positive responses to stress recognition and working conditions than nursing staff. JAG accreditation was associated with positive scores in safety climate and job satisfaction domains. Endo-SAQ met thresholds of construct validity and reliability. Conclusions Endoscopy staff had largely positive safety attitudes scores but there were significant differences across domains and staff. There is evidence for the validity and reliability of Endo-SAQ. Endo-SAQ could complement current measures of patient safety in endoscopy and be used in evaluation and research.

Activin A and pathologies of pregnancy: a review.

Activin A is a two-subunit protein belonging to the transforming growth factor ß superfamily. First discovered almost three decades ago, it has since been implicated in diverse physiological roles, ranging from wound repair to reproduction. After 30 years of research, altered activin A levels are now understood to be associated with the development of various diseases, making activin A a potential therapeutic target. In pregnancy, the placenta and fetal membranes are major producers of activin A, with significantly enhanced serum concentrations now recognised as a contributor to numerous gestational disorders. Evidence now suggests that circulating levels of activin A may be clinically relevant in the early detection of pregnancy complications, including miscarriage and preeclampsia. This review aims to summarise our current understanding of activin A as a potential diagnostic marker in common pregnancy pathologies.
