RESUMEN

BACKGROUND: Health care providers are a key source of reports of infants to child welfare related to birthing people's substance use. Many of these reports are overreports, or reports that exceed what is legally mandated, and reflect racial bias. We developed and evaluated a webinar for health professionals to address overreporting related to birthing people's substance use. METHODS: This evaluation study collected data from health professionals registering to participate in a professional education webinar about pregnancy, substance use, and child welfare reporting. It collected baseline data upon webinar registration, immediate post-webinar data, and 6 month follow-up data. Differences in both pre-post-and 6 month follow-up data were used to examine changes from before to after the webinars in beliefs, attitudes, and practices related to pregnant and birthing people who use drugs and child welfare reporting. RESULTS: 592 nurses, social workers, physicians, public health professionals, and other health professionals completed the baseline survey. More than half of those completing the baseline survey (n = 307, 52%) completed one or both follow-up surveys. We observed statistically significant changes in five of the eleven opioid attitudes/beliefs and in four of the nine child welfare attitudes/beliefs from baseline to follow-ups, and few changes in "control statements," i.e. beliefs we did not expect to change based on webinar participation. All of the changes were in the direction of less support for child welfare reporting. In particular, the proportion agreeing with the main evaluation outcome of "I would rather err on the side of overreporting to child welfare than underreporting to child welfare" decreased from 41% at baseline to 28% and 31% post-webinar and at 6-month follow up (p = 0.001). In addition, fewer participants endorsed reporting everyone at the 6 month follow-up than at baseline (12% to 22%) and more participants endorsed reporting no one at the 6-month follow-up than at baseline (28% to 18%), p = 0.013. CONCLUSIONS: Webinars on the legal, scientific, and ethical aspects of reporting that are co-developed with people with lived experience may be a path to reducing health professional overreporting to child welfare related to birthing people's substance use.

RESUMEN

BACKGROUND: We investigated how a personalized care-planning software and linked mobile-app may aid people to self-manage their type 2 diabetes (T2D) more effectively. RESEARCH DESIGN AND METHODS: People with T2D and glycated hemoglobin (HbA1c) greater than 58 mmol/mol (7.5%) were randomized to either an intervention group receiving a personalized care plan, or the control group receiving usual care. Quality of life (QoL) was measured for both groups using validated questionnaires and one-on-one interviews with a subset of 12 participants from each group. RESULTS: QoL for the active treatment group increased, by their EQ -5D-5 L score increasing on average by 0.046, whereas it decreased for the control group on average by 0.009. The EQ Visual Analogue Score (VAS) of the intervention group also increased by 8.2%, whereas the control group had a reduction in EQ VAS score of 2.8% (p = 0.008 for difference). CONCLUSION: In this prospective RCT, the findings point to how the provision of personalized care plans can result in an improvement in individuals' self-rated QoL. This may lead to longer term health benefits.

RESUMEN

OBJECTIVE: No studies have examined whether alcohol taxes may be relevant for reducing harms related to pregnant people's drinking. METHOD: We examined how beverage-specific ad valorem, volume-based, and sales taxes are associated with outcomes across three data sets. Drinking outcomes came from women of reproductive age in the 1990-2020 US National Alcohol Surveys (N = 11 659 women $\le$ 44 years); treatment admissions data came from the 1992-2019 Treatment Episode Data Set: Admissions (N = 1331 state-years; 582 436 pregnant women admitted to treatment); and infant and maternal outcomes came from the 2005-19 Merative Marketscan® database (1 432 979 birthing person-infant dyads). Adjusted analyses for all data sets included year fixed effects, state-year unemployment and poverty, and accounted for clustering by state. RESULTS: Models yield no robust significant associations between taxes and drinking. Increased spirits ad valorem taxes were robustly associated with lower rates of treatment admissions [adjusted IRR = 0.95, 95% CI: 0.91, 0.99]. Increased wine and spirits volume-based taxes were both robustly associated with lower odds of infant morbidities [wine aOR = 0.98, 95% CI: 0.96, 0.99; spirits aOR = 0.99, 95% CI: 0.98, 1.00] and lower odds of severe maternal morbidities [wine aOR = 0.91, 95% CI: 0.86, 0.97; spirits aOR = 0.95, 95% CI: 0.92, 0.97]. Having an off-premise spirits sales tax was also robustly related to lower odds of severe maternal morbidities [aOR = 0.78, 95% CI: 0.64, 0.96]. CONCLUSIONS: Results show protective associations between increased wine and spirits volume-based and sales taxes with infant and maternal morbidities. Policies that index tax rates to inflation might yield more public health benefits, including for pregnant people and infants.

RESUMEN

Multimorbidity (multiple conditions) and polypharmacy (multiple medications) are increasingly common, yet there is a need to better understand the prevalence of co-occurrence. In this systematic review, we examined the prevalence of multimorbidity and polypharmacy among adults (≥18 years) and older adults (≥65 years) in clinical and community settings. Six electronic databases were searched, and 87 studies were retained after two levels of screening. Most studies focused on adults 65 years and older and were done in population-based community settings. Although the operational definitions of multimorbidity and polypharmacy varied across studies, consistent cut-points (two or more conditions and five or more medications) were used across most studies. In older adult samples, the prevalence of multimorbidity ranged from 4·8% to 93·1%, while the prevalence of polypharmacy ranged from 2·6% to 86·6%. High heterogeneity between studies indicates the need for more consistent reporting of specific lists of conditions and medications used in operational definitions.

RESUMEN

INTRODUCTION: Previous research has found that policies specifically focused on pregnant people's alcohol use are largely ineffective. Therefore, the purpose of this study is to analyze the relationships between general population policies regulating alcohol physical availability and outcomes related to pregnant people's alcohol use, specifically infant morbidities and injuries. METHODS: Outcome data were obtained from Merative MarketScan, a longitudinal commercial insurance claims data set. Policy data were obtained from the National Institute on Alcohol Abuse and Alcoholism's Alcohol Policy Information System, the National Alcohol Beverage Control Association, and Liquor Handbooks and merged using policies in effect during the estimated year of conception. Relationships between state-level policies regulating sites, days/hours, and government monopoly of liquor sales and infant morbidities and injuries were examined. Analyses used logistic regression with individual controls, fixed effects for state and year, state-specific time trends, and SEs clustered by state. The study analysis was conducted from 2021 to 2023. RESULTS: The analytic sample included 1,432,979 infant-birthing person pairs, specifically people aged 25-50 years who gave birth to a singleton between 2006 and 2019. A total of 3.1% of infants had a morbidity and 2.1% of infants had an injury. State government monopoly on liquor sales was associated with reduced odds of infant morbidities and injuries, whereas gas station liquor sales were associated with increased odds of infant morbidities and injuries. Allowing liquor sales after 10PM was associated with increased odds for infant injuries. No effect was found for allowing liquor sales in grocery stores or on Sundays. CONCLUSIONS: Findings suggest that limiting alcohol availability for the general population may help reduce adverse infant outcomes related to pregnant people's alcohol use.

RESUMEN

INTRODUCTION: Stigma is a well-known barrier to HIV testing and treatment and is an emerging barrier to pre-exposure prophylaxis (PrEP) use. To guide future research, measurement and interventions, we developed a conceptual framework for PrEP stigma among adolescent girls and young women (AGYW) in sub-Saharan Africa, a priority population for PrEP. METHODS: A literature review, expert consultations and focus group discussions (FGDs) were conducted to adapt the Health Stigma and Discrimination Framework, describing the stigmatization process nested within the socio-ecological framework. We reviewed all articles on PrEP stigma and on HIV, contraceptive or sexuality stigma among AGYW from 2009 to 2019. Expert consultations were conducted with 10 stigma or PrEP researchers and two Kenyan youth advisory boards to revise the framework. Finally, FGDs were conducted with AGYW PrEP users (4 FGDs; n = 20) and key influencers (14 FGDs; n = 72) in Kenya with the help of a Youth Research Team who aided in FGD conduct and results interpretation. Results from each phase were reviewed and the framework was updated to incorporate new and divergent findings. This was validated against an updated literature search from 2020 to 2023. RESULTS: The conceptual framework identifies potential drivers, facilitators and manifestations of PrEP stigma, its outcomes and health impacts, and relevant intersecting stigmas. The main findings include: (1) PrEP stigma is driven by HIV, gender and sexuality stigmas, and low PrEP community awareness. (2) Stigma is facilitated by factors at multiple levels: policy (e.g. targeting of PrEP to high-risk populations), health systems (e.g. youth-friendly service availability), community (e.g. social capital) and individual (e.g. empowerment). (3) Similar to other stigmas, manifestations include labelling, violence and shame. (4) PrEP stigma results in decreased access to and acceptability of PrEP, limited social support and community resistance, which can impact mental health and decrease PrEP uptake and adherence. (5) Stigma may engender resilience by motivating AGYW to think of PrEP as an exercise in personal agency. CONCLUSIONS: Our PrEP stigma conceptual framework highlights potential intervention targets at multiple levels in the stigmatization process. Its adoption would enable researchers to develop standardized measures and compare stigma across timepoints and populations as well as design and evaluate interventions.

RESUMEN

Introduction: C3 glomerulopathy (C3G) is an ultrarare renal disease characterized by deposition of complement component C3 in the glomerular basement membrane (GBM). Rare and novel genetic variation in complement genes and autoantibodies to complement proteins are commonly identified in the C3G population and thought to drive the underlying complement dysregulation that results in renal damage. However, disease heterogeneity and rarity make accurately defining characteristics of the C3G population difficult. Methods: Here, we present a retrospective analysis of the Molecular Otolaryngology and Renal Research Laboratories C3G cohort. This study integrated complement biomarker testing and in vitro tests of autoantibody function to achieve the following 3 primary goals: (i) define disease profiles of C3G based on disease drivers, complement biomarkers, and age; (ii) determine the relationship between in vitro autoantibody tests and in vivo complement dysregulation; and (iii) evaluate the association between autoantibody function and disease progression. Results: The largest disease profiles of C3G included patients with autoantibodies to complement proteins (48%) and patients for whom no genetic and/or acquired drivers of disease could be identified (43%). The correlation between the stabilization of convertases by complement autoantibodies as measured by in vitro modified hemolytic assays and systemic biomarkers that reflect in vivo complement dysregulation was remarkably strong. In patients positive for autoantibodies, the degree of stabilization capacity predicted worse renal function. Conclusion: This study implicates complement autoantibodies as robust drivers of systemic complement dysregulation in approximately 50% of C3G but also highlights the need for continued discovery-based research to identify novel drivers of disease.

RESUMEN

CyVerse, the largest publicly-funded open-source research cyberinfrastructure for life sciences, has played a crucial role in advancing data-driven research since the 2010s. As the technology landscape evolved with the emergence of cloud computing platforms, machine learning and artificial intelligence (AI) applications, CyVerse has enabled access by providing interfaces, Software as a Service (SaaS), and cloud-native Infrastructure as Code (IaC) to leverage new technologies. CyVerse services enable researchers to integrate institutional and private computational resources, custom software, perform analyses, and publish data in accordance with open science principles. Over the past 13 years, CyVerse has registered more than 124,000 verified accounts from 160 countries and was used for over 1,600 peer-reviewed publications. Since 2011, 45,000 students and researchers have been trained to use CyVerse. The platform has been replicated and deployed in three countries outside the US, with additional private deployments on commercial clouds for US government agencies and multinational corporations. In this manuscript, we present a strategic blueprint for creating and managing SaaS cyberinfrastructure and IaC as free and open-source software.

RESUMEN

BACKGROUND: Among pregnant and recently pregnant people we investigated whether legal recreational cannabis is associated with pregnancy-related cannabis use, safety beliefs, and perceived community stigma. METHODS: In 2022, we surveyed 3571 currently and recently pregnant English- or Spanish-speaking adults in 37 states. Primary outcomes included cannabis use during pregnancy and two continuous scale measures of beliefs about safety and perceived community stigma. Using generalized linear models and mixed effects ordinal logistic regression with random effects for state, we assessed associations between legal recreational cannabis and outcomes of interest, controlling for state-level and individual-level covariates and specifying appropriate functional form. RESULTS: Those who reported cannabis use during pregnancy were more likely to believe it is safe and to perceive community stigma compared to those who did not report use during pregnancy. Legal recreational cannabis was not associated with cannabis use during pregnancy, continuation or increase in use, frequency of use, or safety beliefs. Legal recreational cannabis was associated with lower perceived community stigma (coefficient: -0.07, 95% CI: -0.13, -0.01), including among those who reported use during (coefficient = -0.22, 95% CI: -0.40, -0.04) and prior to but not during (coefficient = -0.19, 95% CI: -0.37, -0.01) pregnancy. CONCLUSION: Findings do not support concerns that legal recreational cannabis is associated with cannabis use during pregnancy or beliefs about safety. Legal recreational cannabis may be associated with lower community stigma around cannabis use during pregnancy, which could have implications for pregnant people's disclosure of use and care-seeking behavior.

RESUMEN

Circulating tumour DNA (ctDNA) detection via liquid biopsy is an emerging alternative to tissue biopsy, but its potential in treatment response monitoring and prognosis in triple negative breast cancer (TNBC) is not yet well understood. Here we determined the prevalence of actionable mutations detectable in ctDNA using a clinically validated cancer gene panel assay in patients with TNBC, without recurrence at the time of study entry. Sequencing of plasma DNA and validation of variants from 130 TNBC patients collected within 7 months of primary treatment completion revealed that 7.7% had detectable residual disease with a hotspot panel. Among neoadjuvant treated patients, we observed a trend where patients with incomplete pathologic response and positive ctDNA within 7 months of treatment completion were at much higher risk of reduced progression free survival. We propose that a high risk subset of early TNBC patients treated in neoadjuvant therapy protocols may be identifiable by combining tissue response and sensitive ctDNA detection.

RESUMEN

Renin, an aspartate protease, regulates the renin-angiotensin system by cleaving its only known substrate angiotensinogen to angiotensin. Recent studies have suggested that renin may also cleave complement component C3 to activate complement or contribute to its dysregulation. Typically, C3 is cleaved by C3 convertase, a serine protease that uses the hydroxyl group of a serine residue as a nucleophile. Here, we provide seven lines of evidence to show that renin does not cleave C3. First, there is no association between renin plasma levels and C3 levels in patients with C3 Glomerulopathies (C3G) and atypical Hemolytic Uremic Syndrome (aHUS), implying that serum C3 consumption is not increased in the presence of high renin. Second, in vitro tests of C3 conversion to C3b do not detect differences when sera from patients with high renin levels are compared to sera from patients with normal/low renin levels. Third, aliskiren, a renin inhibitor, does not block abnormal complement activity introduced by nephritic factors in the fluid phase. Fourth, aliskiren does not block dysregulated complement activity on cell surfaces. Fifth, recombinant renin from different sources does not cleave C3 even after 24 hours of incubation at 37 °C. Sixth, direct spiking of recombinant renin into sera samples of patients with C3G and aHUS does not enhance complement activity in either the fluid phase or on cell surfaces. And seventh, molecular modeling and docking place C3 in the active site of renin in a position that is not consistent with a productive ground state complex for catalytic hydrolysis. Thus, our study does not support a role for renin in the activation of complement.

RESUMEN

OBJECTIVES: We aimed to measure both stated and experimentally "revealed" abortion provision preferences among US people with capacity for pregnancy. STUDY DESIGN: In July 2022, we recruited US residents assigned female sex at birth and aged 18 to 55 years using Prolific, an online survey hosting platform. We asked participants what first-trimester abortion method and delivery model they would prefer. We also assessed abortion care preferences with a discrete choice experiment, which examined the relative importance of the following care attributes: method, distance, wait time for appointment, delivery model (telehealth vs in-clinic), and cost. RESULTS: More than half of the 887 respondents (59%) self-reported a slight (22%) or strong (37%) preference for medication compared to aspiration abortion; 11% stated no preference. Our discrete choice experiment found that cost and wait time had a greater effect on hypothetical decision-making than did method and delivery model (discrete choice experiment average importances = 44.3 and 23.2, respectively, compared to 15.9 and 8.2, respectively). Simulations indicated that holding other attributes constant, respondents preferred medication to aspiration abortion and telehealth to in-clinic care. CONCLUSIONS: This study, the first to examine abortion preferences in the United States, using a discrete choice experiment, demonstrates the importance of wait time and cost in abortion care decision-making. Our work indicates that for this population, factors related to health care financing and organization may matter more than clinical aspects of care. IMPLICATIONS: Although people in this study preferred medication to aspiration abortion and telehealth to in-clinic care, wait time and cost of care played a greater role in care decision-making. Focusing solely on clinical aspects of care (i.e., method, delivery model) may ignore other attributes of care that are particularly important for potential patients.

RESUMEN

BACKGROUND: Policies specific to alcohol use during pregnancy have not been found to reduce risks related to alcohol use during pregnancy. In contrast, general population alcohol policies are protective for the general population. Here, we assessed whether US state-level general population alcohol policies are related to drinking outcomes among women of reproductive age. METHODS: We conducted secondary analyses of 1984-2020 National Alcohol Survey data (N = 13,555 women ≤44 years old). State-level policy exposures were government control of liquor retail sales, heavy beer at gas stations, heavy beer at grocery stores, liquor at grocery stores, Sunday off-premise liquor sales, and blood alcohol concentration (BAC) driving limits (no law, 0.10 limit, 0.05-0.08 limit). Outcomes were past 12-month number of drinks, ≥5 drink days, ≥8 drink days, and any DSM-IV alcohol abuse/dependence symptoms. Regressions adjusted for individual and state-level controls, clustering by state, and included fixed effects for survey month and year. RESULTS: Allowing Sunday off-premise liquor sales versus not was related to having 1.20 times as many drinks (95% CI: 1.01, 1.42), 1.41 times as many ≥5 drink days (95% CI: 1.08, 1.85), and 1.91 times as many ≥8 drink days (95% CI: 1.28, 2.83). BAC limits of 0.05-0.08 for driving versus no BAC limit was related to 0.51 times fewer drinks (95% CI: 0.27, 0.96), 0.28 times fewer days with ≥5 drinks (95% CI: 0.10, 0.75), and 0.20 times fewer days with ≥8 drinks (95% CI: 0.08, 0.47). CONCLUSIONS: US state-level policies prohibiting Sunday off-premise liquor sales and BAC limits of 0.05-0.08 for driving are related to less past 12-month overall and heavy drinking among women 18-44 years old.

RESUMEN

INTRODUCTION: Oral pre-exposure prophylaxis (PrEP) has the potential to reduce HIV acquisition among adolescent girls and young women (AGYW) in sub-Saharan Africa, a priority population for epidemic control. However, intimate partner violence (IPV) and low relationship power can create significant challenges to PrEP use. The Tu'Washindi intervention aimed to increase PrEP use by addressing relationship- and violence-related barriers among AGYW enrolled in the DREAMS Initiative in Siaya County, Kenya. METHODS: Our multi-level, community-based intervention was piloted in a cluster-randomized controlled trial conducted at six DREAMS sites from April to December 2019 (NCT03938818). Three intervention components were delivered over 6 months: an eight-session empowerment-based support club, community sensitization targeted towards male partners and a couples' PrEP education event. Participants were ages 17-24, HIV negative and either eligible for, or already taking, PrEP. Over 6 months of follow-up, we assessed IPV (months 3 and 6) and PrEP uptake and continuation (month 6) through interviewer-administered questionnaires; PrEP adherence was assessed with Wisepill electronic monitoring devices. These outcomes were compared using adjusted Poisson and negative binomial regression models. RESULTS: We enrolled 103 AGYW with median age of 22 years (IQR 20-23); one-third were currently taking PrEP and 45% reported IPV in the past 3 months. Retention was 97% at month 6. Compared to the control arm, intervention arm participants were more likely to initiate PrEP, if not already using it at enrolment (52% vs. 24%, aRR 2.28, 95% CI 1.19-4.38, p = 0.01), and those taking PrEP had more days with device openings (25% of days vs. 13%, aRR 1.94, 95% CI 1.16-3.25, p = 0.01). Twenty percent of participants reported IPV during follow-up. There were trends towards fewer IPV events (aIRR 0.66, 95% CI 0.27-1.62, p = 0.37) and fewer events resulting in injury (aIRR 0.21, 95% CI 0.04-1.02, p = 0.05) in the intervention versus control arm. CONCLUSIONS: Tu'Washindi shows promise in promoting PrEP uptake and adherence among AGYW without concomitant increases in IPV; however, adherence was still suboptimal. Further research is needed to determine whether these gains translate to increases in the proportion of AGYW with protective levels of PrEP adherence and to evaluate the potential for the intervention to reduce IPV risk.

RESUMEN

INTRODUCTION: Effective use of oral HIV pre-exposure prophylaxis (PrEP) has been lower among African adolescent girls and young women (AGYW) than among older women, young men who have sex with men, and serodiscordant heterosexual couples in the region. Efforts to build PrEP support have centered around peers and male partners, but the family may also play an important role. This qualitative study aimed to describe family influence on PrEP use among AGYW in in three African cities. METHODS: POWER (Prevention Options for Women Evaluation Research) was a PrEP demonstration project among 2550 AGYW (16-25 years old) in Johannesburg and Cape Town, South Africa and Kisumu, Kenya conducted from 2017 to 2020. In-depth interviews and focus group discussions were conducted with 136 AGYW participants to explore their PrEP views and experiences, including awareness and interest in PrEP; barriers and facilitators to uptake and use; the influence of family, peers, intimate partners, and community; and the key types of support for their PrEP use. Transcripts were coded and analysed thematically. RESULTS: The decision to initiate PrEP was associated with fear and anxiety linked to anticipated stigma from family members, and with family's lived HIV experience. Family disclosure, especially to mothers, was important to participants, as most lived with their families and considered it essential for them to obtain their mother's approval to use PrEP. Most family members, particularly mothers, provided instrumental, emotional, informational and appraisal support to participants using PrEP, including reminders, encouragement, and problem-solving. Participants reported that family members with insufficient information about PrEP safety and efficacy and who voiced concerns were a substantial barrier to their use. However, they often became supportive after receiving more PrEP information. CONCLUSION: Families, particularly mothers, can play an important role in supporting PrEP use. PrEP programmes should leverage family support to help with PrEP persistence by providing basic information to families about PrEP safety and efficacy. AGYW using PrEP should be encouraged to selectively disclose PrEP use to build support and counseled on how to disclose and address family concerns.

RESUMEN

INTRODUCTION: Effective use of pre-exposure prophylaxis (PrEP) has been low among adolescent girls and young women (AGYW) in sub-Saharan Africa. The MTN-034/REACH trial offered AGYW a menu of adherence support strategies and achieved high adherence to both daily oral PrEP and the monthly dapivirine vaginal ring. Understanding how these strategies promoted product use could inform the design of adherence support systems in programmatic settings. METHODS: REACH was a randomized crossover trial evaluating the safety of and adherence to the ring and oral PrEP among 247 HIV-negative AGYW (ages 16-21) in South Africa, Uganda and Zimbabwe from January 2019 to September 2021 (NCT03593655). Adherence support included monthly counselling sessions with drug-level feedback (DLF) plus optional daily short message service (SMS) reminders, weekly phone or SMS check-ins, peer support clubs, "peer buddies" and additional counselling. Counsellors documented adherence support choices and counselling content on standardized forms. Through focus groups, serial in-depth interviews (IDIs) and single IDIs (n = 119 total), we explored participants' experiences with adherence support and how it encouraged product use. RESULTS: Participants received counselling at nearly all visits. DLF was provided at 54.3% of sessions and, across sites, 49%-68% received results showing high adherence for oral PrEP, and 73%-89% for the ring. The most popular support strategies were in-person clubs and weekly calls, followed by online clubs, additional counselling and SMS. Preferences differed across sites but were similar for both products. Qualitative results demonstrated that the REACH strategies supported adherence by providing information about HIV and PrEP, continually motivating participants, and supporting the development of behavioural skills and self-efficacy, aligning with the Information, Motivation, and Behavioural Skills (IMB) model. Effectiveness was supported by three foundational pillars: strong interpersonal relationships with counsellors; ongoing, easily accessible support and resources; and establishing trust in the counsellors and study products through counsellor relationships, peer-to-peer exchange and DLF. CONCLUSIONS: Implementation programmes could support effective PrEP use by offering a small menu of counsellor- and peer-based support options that are youth-friendly and developmentally appropriate. The same menu options can support both ring and oral PrEP users, though content should be tailored to the individual products.

RESUMEN

Understanding community responses to climate is critical for anticipating the future impacts of global change. However, despite increased research efforts in this field, models that explicitly include important biological mechanisms are lacking. Quantifying the potential impacts of climate change on species is complicated by the fact that the effects of climate variation may manifest at several points in the biological process. To this end, we extend a dynamic mechanistic model that combines population dynamics, such as species interactions, with species redistribution by allowing climate to affect both processes. We examine their relative contributions in an application to the changing biomass of a community of eight species in the Gulf of Maine using over 30 years of fisheries data from the Northeast Fishery Science Center. Our model suggests that the mechanisms driving biomass trends vary across space, time, and species. Phase space plots demonstrate that failing to account for the dynamic nature of the environmental and biologic system can yield theoretical estimates of population abundances that are not observed in empirical data. The stock assessments used by fisheries managers to set fishing targets and allocate quotas often ignore environmental effects. At the same time, research examining the effects of climate change on fish has largely focused on redistribution. Frameworks that combine multiple biological reactions to climate change are particularly necessary for marine researchers. This work is just one approach to modeling the complexity of natural systems and highlights the need to incorporate multiple and possibly interacting biological processes in future models.

RESUMEN

Background: Medical professionals are key components of child maltreatment surveillance. Updated estimates of reporting rates by medical professionals are needed. Methods: We use the National Child Abuse and Neglect Data System (2000-2019) to estimate rates of child welfare investigations of infants stemming from medical professional reporting to child welfare agencies. We adjust for missing data and join records to population data to compute race/ethnicity-specific rates of infant exposure to child welfare investigations at the state-year level, including sub-analyses related to pregnant/parenting people's substance use. Results: Between 2010 and 2019, child welfare investigated 2.8 million infants; ∼26% (n=731,705) stemmed from medical professionals' reports. Population-adjusted rates of these investigations stemming doubled between 2010 and 2019 (13.1-27.1 per 1000 infants). Rates of investigations stemming from medical professionals' reports increased faster than did rates for other mandated reporters, such as teachers and police, whose reporting remained relatively stable. In 2019, child welfare investigated ∼1 in 18 Black (5.4%), 1 in 31 Indigenous (3.2%), and 1 in 41 White infants (2.5%) following medical professionals' reports. Relative increases were similar across racial groups, but absolute increases differed, with 1.3% more of White, 1.7% of Indigenous, and 3.1% of Black infants investigated in 2019 than 2010. Investigations related to substance use comprised ∼35% of these investigations; in some states, this was almost 80%. Discussion: Rates of child welfare investigations of infants stemming from medical professional reports have increased dramatically over the past decade with persistent and notable racial inequities in these investigations.

RESUMEN

INTRODUCTION: In response to the diverse roles and strong influence that male partners may have in women's decisions and ability to use HIV prevention products, we previously developed the counselor-administered Healthy Relationship Assessment Tool (HEART). This tool helps counselors tailor pre-exposure prophylaxis (PrEP) adherence support counseling to women's relationship dynamics with their sexual partners, suggesting modules for counselors to deliver. In this study, we examined the extent to which counselors used the HEART to guide the delivery of intervention modules and whether changes in subsequent HEART scores reflected the counseling module(s) received. METHODS: We conducted this study during a randomized controlled trial of the Community Health clinic model for Agency in Relationships and Safer Microbicide Adherence (CHARISMA) counseling intervention in Johannesburg, South Africa. Trained lay counselors administered the HEART to intervention group participants at enrollment (n=203) and at 3- and 6-month follow-up visits between October 2018 and April 2021. The HEART auto-calculated participants' response scores to recommend relevant counseling modules. We compared the mean scores for the 5 HEART scales across groups receiving different counseling modules. We also assessed changes in scale scores over time by the counseling module received. RESULTS: Although counselors could override HEART counseling module recommendations based on additional knowledge of participants' cases, they consistently agreed with the HEART recommendations. The HEART also triggered the sorting of women into counseling modules that they were positioned to successfully leverage. Additionally, participants' HEART scores changed over time in predictable ways based on the type of counseling module received. CONCLUSION: Overall, the tool performed as predicted and was consistent with past validation efforts of the HEART, indicating that the HEART may provide an efficient means to tailor women's counseling to address relationship-related challenges to PrEP adherence.

RESUMEN

OBJECTIVES: We aimed to explore the psychometric properties of the first known online asynchronous multiple mini-interview (MMI) designed for fairness with subgroup analyses by key characteristics, usability and acceptability. DESIGN: Cross-discipline multimethod evaluation. SETTING: One UK University. PARTICIPANTS: Applicants to nursing, midwifery and paramedic science undergraduate programmes during 2021-2022. PRIMARY, SECONDARY OUTCOME MEASURES: Psychometric properties (internal consistency, construct validity, dimensionality) were assessed using Cronbach's alpha (α), parallel analysis (PA), Schmid-Leiman transformation and ordinal confirmatory factor analysis (CFA). Usability and acceptability were evaluated using descriptive statistics and conventional content analysis. METHODS: The system was configured in a seven question 4 min MMI. Applicants' videorecorded their answers which were later assessed by interviewers and scores summed. Applicants and interviewers completed online evaluation questionnaires. RESULTS: Performance data from 712 applicants determined good-excellent reliability for the asynchronous MMI (mean α 0.72) with similar results across subgroups (gender, age, disability/support needs, UK/non-UK). PA and factor analysis results suggested there were seven factors relating to the MMI questions with an underlying general factor that explained the variance in observed candidate responses. A CFA testing a seven-factor hierarchical model showed an excellent fit to the data (Confirmatory Fit Index=0.99), Tucker Lewis Index=0.99, root mean square error (RMSE) =0.034). Applicants (n=210) viewed the flexibility, relaxed environment and cost savings advantageous. Interviewers (n=65) reported the system to be intuitive, flexible with >70% time saved compared with face-to-face interviews. Reduced personal communication was cited as the principal disadvantage. CONCLUSIONS: We found that the asynchronous MMI was reliable, time-efficient, fair and acceptable and building fairness in was lost-cost. These novel, insights are applicable across health professions selection internationally informing the future configuration of online interviews to ensure workforces represent the societies they serve.
