RESUMEN

Urban life shapes the mental health of city dwellers, and although cities provide access to health, education and economic gain, urban environments are often detrimental to mental health1,2. Increasing urbanization over the next three decades will be accompanied by a growing population of children and adolescents living in cities3. Shaping the aspects of urban life that influence youth mental health could have an enormous impact on adolescent well-being and adult trajectories4. We invited a multidisciplinary, global group of researchers, practitioners, advocates and young people to complete sequential surveys to identify and prioritize the characteristics of a mental health-friendly city for young people. Here we show a set of ranked characteristic statements, grouped by personal, interpersonal, community, organizational, policy and environmental domains of intervention. Life skills for personal development, valuing and accepting young people's ideas and choices, providing safe public space for social connection, employment and job security, centring youth input in urban planning and design, and addressing adverse social determinants were priorities by domain. We report the adversities that COVID-19 generated and link relevant actions to these data. Our findings highlight the need for intersectoral, multilevel intervention and for inclusive, equitable, participatory design of cities that support youth mental health.

RESUMEN

Alcohol's link with sexuality is long-standing and prominent. While research continues to document robust associations between drinking and sexual behavior, scientific attention now centers primarily on evaluating mechanisms and attendant theoretical frameworks to advance our understanding of how alcohol exerts a causal impact. We describe four domains with reliable evidence of alcohol effects: sexualized social perceptions, sexual arousal, sexual risk taking, and sexual assault. We consider three contextual frames: distal factors associated with encountering opportunities for alcohol-involved sex, proximal factors associated with alcohol's acute effects, and distal-proximal interactions. We then examine the empirical support for mechanisms embedded within four theoretical frameworks: alcohol disinhibition, alcohol expectancy, alcohol myopia, and emotion regulation. Support for disinhibition mechanisms is evident with sexual arousal only. Expectancy and myopia mechanisms enjoy support across domains and make up bases for integrative expectancy-myopia causal explanations. Emotion regulation mechanisms evidence preliminary support in risk taking and sexual assault. Implications and future directions are considered.

RESUMEN

BACKGROUND: Pre-exposure prophylaxis (PrEP) is highly effective at reducing the risk of human immunodeficiency virus (HIV) acquisition in at-risk individuals; however, it is largely underutilized. The Veterans Health Administration has created an HIV PrEP dashboard to identify at-risk veterans in attempt to increase PrEP enrollment. OBJECTIVE: This study aimed to determine whether the use of an HIV PrEP dashboard would prove effective at increasing PrEP enrollment at a single facility. METHODS: This was a single-center quality improvement project. Three pharmacists used the HIV PrEP dashboard and retrospective chart review to identify eligible patients for PrEP. A multimodal process of contacting patients was conducted. The primary objective was to evaluate the number of patients who enrolled in PrEP during the study period. Secondary objectives included evaluating the ability of the HIV PrEP dashboard to identify eligible patients, identify effective strategies to target PrEP enrollment, and compare those patients who accepted with those who declined PrEP to evaluate barriers to enrollment. RESULTS: Of the 94 patients reviewed, 26 patients (27.7%) were found eligible for PrEP. Of the eligible patients, 3 patients (11.5%) were enrolled, and 7 patients (26.9%) declined PrEP. The others were lost to follow-up (9 of 26, 34.6%), had no action taken on a chart note to provider (6 of 26, 23.1%), or did not have a primary care provider assigned at the local facility (1 of 26, 3.9%). The 3 patients who were successfully enrolled in PrEP were all contacted and prescribed PrEP through the infectious diseases (ID) clinic. There were no statistically significant differences between the cohorts of patients who accepted and declined PrEP. CONCLUSIONS: The use of an HIV PrEP dashboard aided in identifying eligible patients for PrEP. Enrollment through the ID clinic was the most successful modality. Further research is needed to characterize barriers to PrEP uptake and to develop strategies to increase prescribing from non-ID providers.

RESUMEN

Purpose: Cefepime is an antibiotic associated with cefepime induced neurotoxicity (CIN), particularly in those with reduced renal function, or in cases of inappropriate medication dosing. This report describes a case of CIN associated with a change in infusion duration from 180 to30 minutes, which to the best of our knowledge has not been previously reported in the literature. Summary: A 73-year old male was treated with extended infusion cefepime over 180 minutes while hospitalized with recurrent pneumonia. On discharge, cefepime was continued as outpatient parenteral antimicrobial therapy (OPAT) administered over 30 minutes. The patient began to experience symptoms of neurotoxicity after 1 day of receiving OPAT, which subsequently led to a readmission as neurological symptoms worsened. Cefepime was discontinued and symptoms resolved within 48 hours. Renal function was stable throughout treatment and no other causes for neurotoxicity were noted. Conclusion: This is a unique case of CIN secondary to shortened infusion time, which is clinically relevant, particularly during transitions of care. Further investigation, including more widespread use of therapeutic drug monitoring will be beneficial to further elucidate the relationship between infusion time and CIN development.

RESUMEN

Despite the effectiveness of male condoms, many Female Sex Workers (FSWs) report using condoms infrequently with multiple clients during sexual activity. As such, inconsistent condom use by FSWs is a public health concern as it can increase STI and HIV transmission. This systematic review synthesized extant evidence regarding barriers to condom use experienced by FSWs in the U.S and U.S. - Mexico border towns. The search was conducted through PubMed, CINAL, Cochrane, Medline, and PsychInfo. Studies were included if: they were conducted in the U.S. or U.S. - Mexico borders, their target population was FSWs, they examined condom use barriers experienced by FSWs, and they were published in English between 2011 and February 2021. Condom use barriers among FSWs were reported in all the articles including alcohol consumption and drug use before sex, venue stability, socio-economic status vulnerability, violence and gendered power dynamics, trust of regular clients, and age. The review findings indicate the need to develop interventions promoting condom use for both FSWs and their clients, as well as alternative interventions for HIV prevention such as pre-exposure prophylaxis (PrEP).

RESUMEN

Despite the continued prevalence of HIV and condoms' proven effectiveness in HIV prevention, many young men continue to engage in condom use resistance (CUR). Research shows that sexual compulsivity and childhood sexual abuse (CSA) victimization are risk factors for CUR. Given that sexual activity between men is the most common method through which HIV is transmitted, and that men who have sex with men and women (MSMW) are up to five times as likely to contract or transmit HIV as men who have sex with women only (MSWO), understanding the CUR behaviors of MSMW is uniquely important. Young, single men who had had sex with a woman in the past year (N = 623) completed questionnaires assessing their previous sexual experiences with men and women, history of CSA, sexual compulsivity, and CUR to determine how MSMW classification may moderate the associations between these variables. Results revealed full, moderated mediation, such that CSA was significantly associated with sexual compulsivity among MSMW, but not MSWO. Furthermore, sexual compulsivity was subsequently associated with CUR, in a model accounting for 5.35% of CUR variance. Such findings suggest that exposure to CSA may render MSMW especially susceptible to maladaptive, sexually compulsive desires and behaviors. As a result, MSMW may be more likely to disregard the inherent risks associated with condomless sexual activity and engage in CUR. Thus, intervention programs seeking to reduce the transmission of HIV and other STIs should prioritize targeting MSMW who experienced CSA to reduce sexual compulsivity and increase condom use.

RESUMEN

PURPOSE: The purpose of this study was to explore relationships between postoperative opioid administration and posttraumatic stress symptoms (PTSS) in preschool-aged children surviving cardiac surgery. DESIGN AND METHODS: This was a cross-sectional, descriptive study using survey administration and medical chart review. Primary caregivers of children aged three to six years who underwent cardiac surgery at our institution between 2018 and 2020 were invited to participate. Opioid administration was calculated according to morphine milligram equivalents and indexed to the child's body weight. Caregivers completed the Young Child Posttraumatic Stress Disorder Checklist to explore child PTSS. We used correlational methods to assess the strength and direction of relationships between postoperative opioid administration and child PTSS. RESULTS: We did not find a statistically significant relationship between total postoperative opioid administration and child PTSS. When analyzing individual opioid agents, morphine did show a significant inverse relationship to YCPC scores (rs = -.57, p = .017) in children with single ventricle physiology. CONCLUSIONS: Total postoperative opioid administration was not statistically significantly related to child PTSS in our sample. Differing patterns of association were noted among children with single- versus bi-ventricular physiology. Postoperative morphine administration was favorably associated with PTSS in children with single-ventricle physiology. PRACTICE IMPLICATIONS: Nurses caring for preschool children who undergo cardiac surgery should anticipate the potential development of PTSS in their patients. Studies using larger sample sizes and longitudinal design are needed to replicate the significant relationship between morphine administration and PTSS in preschoolers with single-ventricle physiology.

RESUMEN

This study assessed the role of mental health symptoms and motives for sex in the association between childhood sexual abuse (CSA) and sexual risk-taking among men who have sex with women (MSW). The sample consisted of young adult (ages 21 to 30), non-monogamous MSW (N = 532) who reported having condomless sex at least once in the past year. Due to alcohol-related aims from two larger studies from which the data were analyzed, participation was excluded to men who regularly consumed alcohol (3 to 35 weekly drinks) and reported no symptoms of alcohol use disorder. Participants answered background questionnaires in lab and then completed a six-week, follow-up survey assessing the number of sex partners and condom use during the prior six weeks. CSA survivors reported greater mental health symptoms and sex motives related to coping, self-affirmation, and partner approval relative to non-survivors. CSA, sex for partner approval, and sex to enhance motives were positively associated with the number of sex partners. Participants endorsing self-affirmation sex motives reported higher condom use than those who did not. CSA contributes to long-term mental and sexual health outcomes among MSW. Identifying and treating depressive and anxiety symptoms and motives for sex may improve sexual health among CSA survivors.

RESUMEN

Understanding the mechanisms underlying the association between lower socioeconomic status (SES) and Intimate Partner Aggression (IPA) is necessary for decreasing risk for IPA among lower-SES individuals. As limited control over one's external environment impacts individuals' ability to internally control their emotional states, the present study examined impulsivity and anger as serial mediators in the association from SES to IPA perpetration. Structural equation modeling analyses (N = 430 men, Mage = 24.66, 66.8% White) showed direct effects from lower SES to higher physical and sexual IPA. Additionally, there was a marginally significant indirect effect from SES to psychological IPA via higher impulsivity and anger. These findings may inform the development of interventions, showing that self-regulatory skills training may help lower psychological aggression. To address physical and sexual IPA, efforts that directly target the detriments of lower SES - via financial, housing, or educational support programs - may be indicated.

RESUMEN

BACKGROUND AND OBJECTIVES: Research has not yet investigated how the association between alcohol and alcohol-related consequences differs across cisgender heterosexual women (CHW), cisgender heterosexual men (CHM), and sexual and gender minority (SGM) college students. METHODS: Participants were N = 754 college students (34.5% CHW [n = 260]; 34.5% CHM [n = 260]; 31.0% SGM [n = 234]) between the ages 18 and 25 who completed a survey on sexual orientation, gender identity, alcohol use (i.e., average drinks per week), and alcohol-related consequences. RESULTS: Among individuals who reported alcohol use, CHM reported significantly more drinks per week compared to CHW and SGM. The logistic model of a zero-inflated negative binomial regression indicated that excess zeros in the alcohol-related consequences were more likely among (1) nondrinkers and (2) SGM compared to CHM. The count portion of the model indicated that, among drinkers, there was a positive association between drinks per week and alcohol-related consequences. Estimated alcohol-related consequences per drink were 1.90% higher among CHW than CHM and 2.76% higher among SGM than CHM. Exploratory analyses did not find significant differences in outcomes between cisgender female and male sexual minority students. DISCUSSION AND CONCLUSION: Findings suggest that although CHW and SGM students consume less alcohol than CHM, these students experience more alcohol-related consequences per drink. SCIENTIFIC SIGNIFICANCE: This study advances the field's knowledge of alcohol use patterns and consequences among SGM college students. There is a need for alcohol education programming that is tailored to the unique experiences, identities, and minority stressors of SGM college students.

RESUMEN

Subclinical cardiotoxicity at low total cumulative doxorubicin (DOX) doses can manifest into cardiomyopathy in long-term cancer survivors. However, the underlying mechanisms are poorly understood. In male B6C3F1 mice, assessment of cardiac function by echocardiography was performed at 1, 4, 10, 17, and 24 weeks after exposure to 6, 9, 12, and 24 mg/kg total cumulative DOX doses or saline (SAL) to monitor development of delayed-onset cardiotoxicity. The 6- or 9-mg/kg total cumulative doses resulted in a significant time-dependent decline in systolic function (left ventricular ejection fraction (LVEF) and fractional shortening (FS)) during the 24-week recovery although there was not a significant alteration in % LVEF or % FS at any specific time point during the recovery. A significant decline in systolic function was elicited by the cardiotoxic cumulative DOX dose (24 mg/kg) during the 4- to 24-week period after treatment compared to SAL-treated counterparts. At 24 weeks after DOX treatment, a significant dose-related decrease in the expression of genes and proteins involved in sarcoplasmic reticulum (SR) calcium homeostasis (Ryr2 and Serca2) was associated with a dose-related increase in the transcript level of Casp12 (SR-specific apoptosis) in hearts. These mice also showed enhanced apoptotic activity in hearts indicated by a significant dose-related elevation in the number of apoptotic cardiomyocytes compared to SAL-treated counterparts. These findings collectively suggest that a steady decline in SR calcium handling and apoptosis might be involved in the development of subclinical cardiotoxicity that can evolve into irreversible cardiomyopathy later in life.

RESUMEN

Formaldehyde (FA) is an irritating, highly reactive aldehyde that is widely regarded as an asthmagen. In addition to its use in industrial applications and being a product of combustion reaction and endogenous metabolism, FDA-regulated products may contain FA or release FA fumes that present toxicity risks for both patients and healthcare workers. Exposure to airborne FA is associated with nasal neoplastic lesions in both animals and humans. It is classified as a Group 1 carcinogen by International Agency for Research on Cancer (IARC) based on the increased incidence of cancer in animals and a known human carcinogen in the Report on Carcinogens by National Toxicology Program (NTP). Herein, we systematically evaluated the tissue responses to FA fumes in an in vitro human air-liquid-interface (ALI) airway tissue model. Cultures were exposed at the air interface to 7.5, 15, and 30 ppm of FA fumes 4 h per day for 5 consecutive days. Exposure to 30 ppm of FA induced sustained oxidative stress, along with functional changes in ciliated and goblet cells as well as possible squamous differentiation. Furthermore, secretion of the proinflammatory cytokines, IL-1ß, IL-2, IL-8, GM-CSF, TNF-a and IFN-γ, was induced by repeated exposures to FA fumes. Expression of MMP-1, MMP-3, MMP-7, MMP-10, MMP-12, and MMP-13 was downregulated at the end of the 5-day exposure. Although DNA-damage was not detected by the comet assay, FA exposures downregulated the DNA repair enzymes MGMT and FANCD2, suggesting its possible interference in the DNA repair capacity. Overall, a general concordance was observed between our in vitro responses to FA fume exposures and the reported in vivo toxicity of FA. Our findings provide further evidence supporting the application of the ALI airway system as a potential in vitro alternative for screening and evaluating the respiratory toxicity of inhaled substances.

RESUMEN

Glutaraldehyde (GA) has been cleared by the Center for Devices and Radiological Health (CDRH) of the Food and Drug Administration (FDA) as a high-level disinfectant for disinfecting heat-sensitive medical equipment in hospitals and healthcare facilities. Inhalation exposure to GA is known to cause respiratory irritation and sensitization in animals and humans. To reproduce some of the known in vivo effects elicited by GA, we used a liquid aerosol exposure system and evaluated the tissue responses in a human in vitro airway epithelial tissue model. The cultures were treated at the air interface with various concentrations of GA aerosols on five consecutive days and changes in tissue function and structure were evaluated at select timepoints during the treatment phase and after a 7-day recovery period. Exposure to GA aerosols caused oxidative stress, inhibition of ciliary beating frequency, aberrant mucin production, and disturbance of cytokine and matrix metalloproteinase secretion, as well as morphological transformation. Some effects, such as those on goblet cells and ciliated cells, persisted following the 7-day recovery period. Of note, the functional and structural disturbances observed in GA-treated cultures resemble those found in ortho-phthaldehyde (OPA)-treated cultures. Furthermore, our in vitro findings on GA toxicity partially and qualitatively mimicked those reported in the animal and human survey studies. Taken together, observations from this study demonstrate that the human air-liquid-interface (ALI) airway tissue model, integrated with an in vitro exposure system that simulates human inhalation exposure, could be used for in vitro-based human hazard identification and the risk characterization of aerosolized chemicals.

RESUMEN

Coercive Condom Use Resistance (CUR) is a significant problem, associated with increases in STIs, unplanned pregnancy, feelings of betrayal, and a loss of sexual autonomy. Furthermore, young men are much more likely to perpetrate coercive CUR than young women. Thus, the present study sought to examine the past experiences, trait characteristics, and state emotions which may precede coercive CUR perpetration intentions, including alcohol intoxication, childhood emotional abuse, trait impulsivity, sexual sensation seeking, state impulsivity, and state anxiety, using an alcohol administration procedure. Young, single, non-problem drinking, and sexually active men who have sex with women from the United States (N = 297; 66% White, 9.4% Black, 10.7% Multi-racial, 5.1% Asian, 1.0% Native American, 1.0% Pacific Islander, and 10.4% Hispanic or Latino) were recruited for participation. They were randomly assigned to either receive alcohol or remain sober before projecting themselves into a hypothetical sexual scenario with a woman who asked to use a condom. Results showed that greater levels of childhood emotional abuse were associated with increased trait impulsivity and sexual sensation seeking, and that sexual sensation seeking was associated with increased state impulsivity and subsequent anxiety during the scenario. Finally, alcohol intoxication moderated the relationship between state anxiety and coercive CUR such that state anxiety was positively associated with coercive CUR among intoxicated men only. Findings suggest that interventions targeting coercive CUR behavior may be improved by focusing on men who have experienced childhood trauma, as well as their alcohol consumption and in-the-moment experiences of impulsivity and anxiety.

RESUMEN

D-glucosamine is a widely consumed dietary supplement used to promote joint health and treat osteoarthritis. It also stimulates intracellular hexosamine flux and increases transforming growth factor ß1 (TGFß1) mRNA expression and insulin resistance in animal studies. The effects of D-glucosamine exposure were investigated in obese Zucker rats. Male (leprfa/leprfa) Zucker rats were exposed to 30, 120, 300 and 600 mg D-glucosamine HCl per kg/day either alone or with chondroitin sulfate (24, 96, 240 and 480 mg/kg/day respectively) for 90 days. After 4 weeks exposure, these doses produced CmaxD-glucosamine concentrations of up to 24 µM in tail vein serum concurrent with a transient 30% increase in blood glucose concentration in the 600 mg/kg/day dose group. D-Glucosamine did not significantly alter body weight, blood glucose or serum insulin levels at any dose tested after 13 weeks exposure, but did increase urinary TGFß1 concentrations. The Zucker rats developed nephropathy and scrotal sores that were related to their hyperglycemia and obesity, and D-glucosamine exposure exacerbated these conditions to a small extent. The incidence of pulmonary osseous metaplasia was increased in rats exposed to D-glucosamine and a single incidence of adrenal osseous metaplasia was noted in one animal exposed to 600/480 mg D-glucosamine HCl/chondroitin sulfate. These lesions may have been treatment related. These studies suggest that the risk of adverse effects of oral D-glucosamine is small compared to that of hyperglycemia in these animals, but the potential for TGFß1-mediated pathologies, such as osseous metaplasia and renal nephropathy may be increased.

RESUMEN

Ortho-phthalaldehyde (OPA) is a chemical disinfectant used for the high-level sterilization of heat-sensitive medical instruments. Although OPA is considered a safer alternative to glutaraldehyde, no exposure limits have been established for respiratory exposures to ensure the safety of OPA sterilization and the safe use of OPA-treated medical instruments. In order to address data gaps in the toxicological profile of OPA, we treated human in vitro air-liquid-interface (ALI) airway cultures at the air interface with various concentrations of OPA aerosols for 10 consecutive days. Temporal tissue responses were evaluated at multiple time points during the treatment phase as well as 10 days following the last exposure. The disturbance of glutathione (GSH) homeostasis occurred as early as 20 min following the first exposure, while oxidative stress persisted throughout the treatment phase, as indicated by the sustained induction of heme oxygenase-1 (HMOX-1) expression. Repeated exposures to OPA aerosols resulted in both functional and structural changes, including the inhibition of ciliary beating frequency, aberrant mucin production, decreases in airway secretory cells, and tissue morphological changes. While OPA-induced oxidative stress recovered to control levels after a 10 day recovery period, functional and structural alterations caused by the high concentration of OPA aerosols failed to fully recover over the observation period. These findings indicate that aerosolized OPA induces both transient and relatively persistent functional and structural abnormalities in ALI cultures under the conditions of the current study.

RESUMEN

HIV/AIDS remains a significant health threat and alcohol is a robust contributing factor. After 25 years of alcohol challenge studies investigating alcohol-related behavioral risk (ARBR), much has been learned delineating how drinking influences sexual transmission. We examine this research and consider its relevance for interventions in the era of antiretrovirals. We consider prototypic alcohol challenge methods, illustrative findings, and prevention/intervention implications, noting three perspectives: (a) scale up/extend existing interventions, including identifying under-targeted risk groups and intersecting with PrEP/PEP interventions; (b) modify existing interventions by cultivating psychoeducational content related to alcohol expectancies, alcohol myopia, sexual arousal, risk perception, sexual abdication, and condom use resistance; and (c) innovate new interventions through Science of Behavior Change approaches and repurposing ARBR paradigms. Finally, we suggest research directions concluding that until HIV incidence diminishes significantly, psychosocial interventions addressing the nexus of alcohol use, sexual transmission, and adherence to biomedical protocols will be an important priority.

RESUMEN

Exposure to cigarette smoke (CS) is a known risk factor in the pathogenesis of smoking-caused diseases, such as chronic obstructive pulmonary diseases (COPD) and lung cancer. To assess the effects of CS on the function and phenotype of airway epithelial cells, we developed a novel repeated treatment protocol and comprehensively evaluated the progression of key molecular, functional, and structural abnormalities induced by CS in a human in vitro air-liquid-interface (ALI) airway tissue model. Cultures were exposed to CS (diluted with 0.5 L/min, 1.0 L/min, and 4.0 L/min clean air) generated from smoking five 3R4F University of Kentucky reference cigarettes under the International Organization for Standardization (ISO) machine smoking regimen, every other day for 4 weeks (3 days per week, 40 min/day). By integrating the transcriptomics-based approach with the in vitro pathophysiological measurements, we demonstrated CS-mediated effects on oxidative stress, pro-inflammatory cytokines and matrix metalloproteinases (MMPs), ciliary function, expression and secretion of mucins, and squamous cell differentiation that are highly consistent with abnormalities observed in airways of smokers. Enrichment analysis on the transcriptomic profiles of the ALI cultures revealed key molecular pathways, such as xenobiotic metabolism, oxidative stress, and inflammatory responses that were perturbed in response to CS exposure. These responses, in turn, may trigger aberrant tissue remodeling, eventually leading to the onset of respiratory diseases. Furthermore, changes of a panel of genes known to be disturbed in smokers with COPD were successfully reproduced in the ALI cultures exposed to CS. In summary, findings from this study suggest that such an integrative approach may be a useful tool for identifying genes and adverse cellular events caused by inhaled toxicants, like CS.

RESUMEN

Sexual aggression perpetration is a public health epidemic, and burgeoning research aims to delineate risk factors for individuals who perpetrate completed rape. The current study investigated physical and psychological intimate partner violence (IPV) history, coercive condom use resistance (CUR), and heavy episodic drinking (HED) as prospective risk factors for rape perpetration. Young adult men (N = 430) ages 21-30 completed background measures as well as follow-up assessments regarding rape events perpetrated over the course of 3 months. Negative binomial regression with log link function was utilized to examine whether these risk factors interacted to prospectively predict completed rape. There was a significant interaction between physical IPV and HED predicting completed rape; men with high HED and greater physical IPV histories perpetrated more completed rapes during follow-up than men with low HED at the same level of physical IPV. Moreover, psychological IPV and coercive CUR interacted to predict completed rape such that men with high coercive CUR and greater psychological IPV histories perpetrated more completed rapes throughout the follow-up period than men with low coercive CUR at the same level of psychological IPV. Findings suggest targets for intervention efforts and highlight the need to understand the topography of different forms of aggression perpetration.

RESUMEN

Per principles outlined in the Belmont Report, research involving human subjects should minimize risks to participants and maximize benefits to participants and society. Recruitment of participants should be equitable. Once enrolled, participants have the right to withdraw at any point. Researchers must balance these principles with pressures to meet enrollment goals and, in the context of repeated-measures designs, retain participants across time. The purpose of this perspective is to describe the approach and corresponding activities for recruiting and retaining underrepresented and vulnerable populations that are the focus of a transdisciplinary academic research center. To this effort, we offer diverse disciplinary backgrounds, experience working with a wide range of populations (from infants to older adults and across multiple health conditions), and spanning a variety of research designs. Effective strategies offered include partnering with community entities, approaching potential participants where they are and at a time of readiness, using population-appropriate modes of communication and data collection, conducting study activities in familiar settings and at convenient times, maintaining frequent contact, and offering meaningful incentives. These strategies are consistent with population-specific reports found in the extant literature and underscore their cross-cutting nature, with adaptations based on participant and community partner needs and preferences.
