A secondary gendered analysis of interviews with Latina cisgender women indicated for HIV pre-exposure prophylaxis

HIV infections disproportionately impact Latinx populations in the United States, yet oral pre-exposure prophylaxis (PrEP) uptake is low. This study was a secondary gendered analysis of interviews with Latina cisgender women (n = 20) recruited from an urban safety net hospital inNew York City between August 2019 and October 2022. All women were indicated for PrEP by the provider. In-depth interviews were conducted with participants in English and Spanish and asked about social determinants of health, sexual partnerships and behaviors, and PrEP-specific enablers and barriers. Secondary thematic content analysis was conducted to identify gender-related factors influencing PrEP uptake. The following themes emerged from the data:structural factors (e.g., employment), partner-related factors, low sexual health knowledge, and resilience and empowerment. Partner-related factors were the most salient; partner infidelity served as reasons for initiating PrEP. Despite being constrained by low power in relationships, women made empowered choices to initiate PrEP and protect themselves. Findings indicated that the impact of gender inequity was an important factor in Latina women's PrEP decision making, pointing to a need to address partner-driven HIV risk, imbalance of power in relationships, and gender norms.

Protocol for a prospective, randomized, controlled trial of Mental Contrasting with Implementation Intentions (MCII) to enhance the effectiveness of VA's MOVE! weight management program: WOOP (Wish, Outcome, Obstacle, Plan) VA

INTRODUCTION

Intensive weight management programs are effective but often have low enrollment and high attrition. Lack of motivation is a key psychological barrier to enrollment, engagement, and weight loss. Mental Contrasting with Implementation Intentions (MCII) is a unique imagery technique that increases motivation for behavior change. We describe our study protocol to assess the efficacy and implementation of MCII to enhance the effectiveness of VA's MOVE! or TeleMOVE! weight management programs using a procedure called "WOOP" (Wish, Outcome, Obstacle, Plan) for Veterans. We hypothesize that WOOP+MOVE! or TeleMOVE! (intervention) will lead to greater MOVE!/TeleMOVE! program engagment and consequently weight loss than MOVE!/TeleMOVE! alone (control).

METHOD

Veterans are randomized to either the intervention or control. Both arms receive the either MOVE! or TeleMOVE! weight management programs. The intervention group receives an hour long WOOP training while the control group receives patient education. Both groups receive telephone follow up calls at 3 days, 4 weeks, and 2 months post-baseline. Eligible participants are Veterans (ages 18-70 years) with either obesity (BMI ≥ 30 kg/m2) or overweight (BMI ≥ 25 kg/m2) and an obesity-associated co-morbidity. At baseline, 6 and 12 months, we assess weight, diet, physical activity in both groups. The primary outcome is mean percent weight change at 6 months. Secondary outcomes include changes in waist circumference, diet, physical activity, and dieting self-efficacy and engagement in regular physical activity. We assess implementation using the RE-AIM framework.

CONCLUSION

If WOOP VA is found to be efficacious, it will be an important tool to facilitate weight management and improve weight outcomes.

Co-delivery of HIV pre-exposure prophylaxis (PrEP) and HIV testing among publicly insured adolescents and young adults (AYA) receiving medication for opioid use disorder (MOUD)

BACKGROUND

Low rates of HIV pre-exposure prophylaxis (PrEP) prescribing contribute to the disproportionate burden of HIV in the United States. Among adolescent and young adults (AYA) with opioid use disorder, HIV testing and PrEP co-prescription rates are poorly characterized.

METHODS

We performed a retrospective analysis involving deidentified data from Philadelphia's Medicaid beneficiaries ages 16-29 years who were prescribed medication for opioid use disorder (MOUD) from 2015 to 2020 and continuously Medicaid-enrolled for ≥6 months prior to that prescription. After identifying the presence of a qualifying diagnosis signifying a PrEP indication, we examined the outcome of appropriate PrEP co-prescriptions and HIV testing using generalized estimating equations (GEE) modeling.

RESULTS

We identified 795 AYA Medicaid beneficiaries with 1269 qualified treatment episodes. We calculated a PrEP prescribing rate of 29.47 per 1000 person-years among AYA receiving MOUD. The HIV testing rate was 63.47 per 1000 person-years among AYA receiving MOUD. GEE modeling revealed that individuals receiving methadone were more likely (aOR=2.62, 95% CI=1.06-6.49) to receive HIV testing within 6 months after a PrEP-qualifying diagnosis compared to those receiving other MOUD medications. Those who only saw outpatient behavioral health providers were less likely (aOR=0.48, 95% CI=0.24-0.99) to have received an HIV test within 6 months after the PrEP-qualifying diagnosis compared to those receiving inpatient behavioral health services.

CONCLUSIONS

Co-prescription of PrEP and HIV testing among AYA receiving MOUD was rare in this large urban publicly insured population. Interventions are needed to increase HIV prevention services for this key population of AYA at risk for HIV infection.

Substance use and treatment disparities among Asian Americans, Native Hawaiians, and Pacific Islanders: A systematic review

BACKGROUND

The increasing relevance of substance use disorder (SUD) within the Asian American, Native Hawaiian, and Pacific Islander (AA&NH/PI) communities, particularly amidst rising anti-Asian hate incidents and the disproportionate health and economic challenges faced by the NH/PI community during the COVID-19 pandemic, underscores the urgency of understanding substance use patterns, treatment disparities, and outcomes.

METHODS

Following PRISMA guidelines, 37 out of 231 studies met the search criteria. Study characteristics, study datasets, substance use rates, SUD rates, treatment disparities, treatment quality, completion rates, and analyses disaggregated by the most specific AA&NH/PI ethnic group reported were examined.

RESULTS

Despite increased treatment admissions over the past two decades, AA&NH/PI remain underrepresented in treatment facilities and underutilize SUD care services. Treatment quality and completion rates are also lower among AA&NH/PI. Analyses that did not disaggregate AA and NHPI as distinct groups from each other or that presented aggregate data only within AA or NHPI as a whole were common, but available disaggregated analyses reveal variations in substance use and treatment disparities among ethnic groups. There is also a lack of research in exploring within-group disparities, including specific case of older adults and substance use.

CONCLUSION

To address disparities in access to substance use treatment and improve outcomes for AA&NH/PI populations, targeted interventions and strategic data collection methods that capture diverse ethnic groups and languages are crucial. Acknowledging data bias and expanding data collection to encompass multiple languages are essential for fostering a more inclusive approach to addressing SUD among AA&NH/PI populations.

Experiences of oncology researchers in the Veterans Health Administration during the COVID-19 pandemic

The Veterans Health Administration is chartered "to serve as the primary backup for any health care services needed…in the event of war or national emergency" according to a 1982 Congressional Act. This mission was invoked during the COVID-19 pandemic to divert clinical and research resources. We used an electronic mixed-methods questionnaire constructed using the Theoretical Domains Framework (TDF) and the Capability, Opportunity, and Motivation (COM-B) model for behavior change to study the effects of the pandemic on VHA researchers. The questionnaire was distributed electronically to 118 cancer researchers participating in national VHA collaborations. The questionnaire received 42 responses (36%). Only 36% did not feel that their research focus changed during the pandemic. Only 26% reported prior experience with infectious disease research, and 74% agreed that they gained new research skills. When asked to describe helpful support structures, 29% mentioned local supervisors, mentors, and research staff, 15% cited larger VHA organizations and 18% mentioned remote work. Lack of timely communication and remote work, particularly for individuals with caregiving responsibilities, were limiting factors. Fewer than half felt professionally rewarded for pursuing research related to COVID. This study demonstrated the tremendous effects of the COVID-19 pandemic on research activities of VHA investigators. We identified perceptions of insufficient recognition and lack of professional advancement related to pandemic-era research, yet most reported gaining new research skills. Individualizing the structure of remote work and ensuring clear and timely team communication represent high yield areas for improvement.

Electron Temperature Measurements Using a Two-Filter Soft X-ray Array in VEST

A multichannel soft X-ray (SXR) array has been developed to measure the electron temperature in the Versatile Experiment Spherical Torus (VEST). To estimate electron temperature using the two-filter method applied to SXR intensity, we designed a pinhole camera that has two photodiode arrays with different metallic filters. We also adopted a filter wheel and tested various filter parameters to find the optimal filter set. Through tests, the combination of aluminum and beryllium was found to be the most suitable for the current experimental conditions in VEST. The filtered SXR signals were acquired with a low-noise preamplifier, exhibiting sufficient signal-to-noise ratios for electron temperature estimation based on the intensity ratio of two signals obtained with different filters. The estimated electron temperature from the developed two-filter SXR array showed reasonably matched levels and consistent trends with Thomson scattering measurements. Error contribution from impurity line emission is also discussed.

Impact of Workflow and Educational Interventions on MR Safety in Radiation Oncology

PURPOSE/OBJECTIVE(S)

Magnetic resonance imaging (MRI) is becoming increasingly integrated into radiation oncology (RO) departments with the use of MRI-Linacs and MRI simulation. Due to the number of implants in patients with cancer, adoption of comprehensive patient screening and MR safety workflows in RO is critical. Identifying MR unsafe implants only at the time of MRI simulation leads to same-day cancellations, potentially delaying treatment, and can risk MR safety events (SEs). This quality improvement study evaluated the impact of workflow and educational interventions on MR safety in RO at a single institution.

MATERIALS/METHODS

In an effort to decrease same-day cancellations and improve safety surrounding use of a 3 Tesla MRI simulator at an academic center, three plan-see-do-act (PDSA) cycles were implemented from 4/18/22 - 1/19/23. MR safety oversight for the simulator was provided by a multidisciplinary team, with input from both radiology and RO. PDSA cycle 1 implemented a two-screen functional workflow, adapted from radiology at the same institution. The first screen is completed by the practice coordinator (PC) at the time of scheduling to triage high-risk patients into a work queue (WQ) for further evaluation by the MR safety team. The second screen is performed by the MR technologist (MRT) at the point of care. PDSA cycle 2 involved education for PCs. PDSA cycle 3 was a second PC educational intervention including a visual aide to assist with WQ use. Efficacy was determined by the number of same-day cancellations, patients in the WQ (a measure of the number of patients identified at the initial screen as having an implant), and SEs in each PDSA cycle.

RESULTS

PDSA cycle 1 spanned 56 workdays during which 91 MR simulations were scheduled with 6 cancellations (6.5%). PDSA cycle 2 spanned 84 days during which 173 MR simulations were scheduled with 18 cancellations (10.4%). PDSA cycle 3 spanned 39 workdays and had 94 MR simulations, with 7 cancellations (7.4%). The cancellation rate during each PDSA cycle was 0.11, 0.21, and 0.17 cancellations/day, respectively. The number of patients in the WQ during each PDSA cycle, representing successfully screened high-risk patients, was 0, 0, and 3, respectively. There were no SEs during the study.

CONCLUSION

In this study, an MR safety workflow from radiology was successfully implemented in RO. There were no SEs during the study, but the number of patients successfully screened as high-risk and placed in the WQ increased after repeat PC education. Further increases in WQ use would decrease the demand for implant assessment at point of care, which could decrease burden on the MRT, same day cancellations, and potentially SEs. This will be especially important if case load increases. Future work could expand educational efforts to additional staff.

EquiPrEP: An implementation science protocol for promoting equitable access and uptake of long-acting injectable HIV pre-exposure prophylaxis (LAI-PrEP)

BACKGROUND

Long-acting injectable HIV pre-exposure prophylaxis (LAI-PrEP) was approved by the U.S. Food and Drug Administration in December 2021. This initial phase of implementation represents a prime opportunity to ensure equitable LAI-PrEP provision to communities often underrepresented in PrEP care before disparities in access and uptake emerge. Herein, we describe the EquiPrEP Project which utilizes an equity-oriented implementation science framework to optimize LAI-PrEP rollout in an urban safety-net clinic in New York City.

METHODS

The primary objectives of this project are to: (1) increase LAI-PrEP initiation overall; (2) increase uptake among groups disproportionately impacted by the HIV epidemic; (3) preserve high PrEP retention while expanding use; and (4) identify barriers and facilitators to LAI-PrEP use. EquiPrEP will enroll 210 PrEP-eligible participants into LAI-PrEP care with planned follow-up for one year. We will recruit from the following priority populations: Black and/or Latine men who have sex with men, Black and/or Latine cisgender women, and transgender women and nonbinary individuals. To evaluate implementation of LAI-PrEP, we will utilize equity-focused iterations of the Reach, Effectiveness, Adoption, Implementation, Maintenance (RE-AIM) framework and the Consolidated Framework for Implementation Research (CFIR), in addition to longitudinal surveys and qualitative interviews.

DISCUSSION

Novel LAI-PrEP formulations carry tremendous potential to revolutionize the field of HIV prevention. Implementation strategies rooted in equity are needed to ensure that marginalized populations have access to LAI-PrEP and to address the structural factors that hinder initiation and retention in care.

Non-Partner Sexual Violence Among Asian American, Native Hawaiian, and Pacific Islander Adults: A Scoping Review

The Asian American, Native Hawaiian, and Pacific Islander (AANHPI) population is rapidly growing in the United States. Despite sexual violence being a persistent and significant public health issue, research on this topic among AANHPIs is lacking. The study objective is to conduct a systematic scoping review on the published literature on non-partner sexual violence among AANHPIs to identify gaps and priorities to inform actionable research. The systematic review was conducted following the PRISMA Protocol for Systematic Reviews. Database searches were conducted of MEDLINE, Embase, PsycINFO, and Cochrane Central of Clinical Trials, along with and AgeLine and CINAHL for peer-reviewed articles describing non-partner sexual violence among AANHPIs. The search was limited to articles in English published after 1990. Each citation was reviewed by two trained independent reviewers, with a third researcher resolving any conflicts. Of the 998 articles screened and subsequently 496 full-text articles assessed for eligibility, 38 articles were included in the final analysis. The majority of studies did not report disaggregated data for AANHPI subgroups, with most focusing on East Asian subgroups and little evidence on NHPI communities. Most studies were cross-sectional, quantitative, and employed non-probability sampling. There was a lack of studies on effectiveness of interventions and validity of sexual violence-related measures. Our review provides a first step in mapping the extant literature on non-partner sexual violence among this underserved and under-researched population and will serve as a guide for future research, policy, and intervention.

The Prevalence and Correlates of Diabetes Distress among South Asians Living in New York City (NYC): Baseline Results from a Randomized Trial

Background

Type 2 diabetes (T2D) disproportionately affects South Asians in the United States (US). Living with T2D can be challenging due to the distress it can create for an individual. Distress associated with diabetes, commonly known as diabetes distress (DD), may lead to complications and challenges with the management of diabetes. This study aims to describe the prevalence of DD among a sample of South Asians in New York City (NYC) seeking care in community-based primary care settings and its association with sociodemographic characteristics and clinical measures.

Methods

This study utilized baseline data from the Diabetes Research, Education, and Action for Minorities (DREAM) Initiative, an intervention designed to reduce hemoglobin A1C (HbA1c) among South Asians with uncontrolled T2D in NYC. DD was measured using the Diabetes Distress Scale (DDS). First, descriptive statistics were used to analyze sociodemographic variables. Chi-square tests assessed categorical variables and Wilcoxon Rank Sum tests assessed continuous variables using a Type I error rate of 0.05. Logistic regression was performed to determine if HbA1c and mental health, along with other covariates, were associated with dichotomized DDS subscales.

Results

Overall, 415 participants completed the DDS at baseline. Median age was 56 years (IQR: 48-62). A total of 25.9% had high emotional burden distress, 6.6% had high physician-related distress, and 22.2% had high regimen-related distress based on subscales. In adjusted analyses, individuals with any days of poor mental health had significantly higher odds of overall distress (OR:3.7, p=0.014), emotional burden distress (OR:4.9, p<0.001), and physician-related distress (OR:5.0, p=0.002) compared to individuals with no days of poor mental health. Individuals with higher HbA1c had significantly higher odds of regimen-related distress (OR:1.31, p=0.007).

Conclusions

Findings suggest that DD is prevalent among this sample of South Asians with diagnosed T2D in NYC. Screening for DD in patients with prediabetes/diabetes should be considered by providers to help provide mental and physical health services during primary care visits. Future research can also benefit from a longitudinal analysis of the impact of DD on diabetes self-management, medication adherence, and mental and physical health.

Trial registration

This study uses baseline data from "Diabetes Management Intervention For South Asians" (NCT03333044), which was registered with clinicaltrials.gov on 6/11/2017.

Stakeholder Perspectives on the Impact of COVID-19 on the Implementation of a Community-Clinic Linkage Model in New York City

Community-clinical linkage models (CCLM) have the potential to reduce health disparities, especially in underserved communities; however, the COVID-19 pandemic drastically impacted their implementation. This paper explores the impact of the pandemic on the implementation of CCLM intervention led by community health workers (CHWs) to address diabetes disparities among South Asian patients in New York City. Guided by the Consolidated Framework for Implementation Research (CFIR), 22 stakeholders were interviewed: 7 primary care providers, 7 CHWs, 5 community-based organization (CBO) representatives, and 3 research staff. Semi-structured interviews were conducted; interviews were audio-recorded and transcribed. CFIR constructs guided the identification of barriers and adaptations made across several dimensions of the study's implementation context. We also explored stakeholder-identified adaptations used to mitigate the challenges in the intervention delivery using the Model for Adaptation Design and Impact (MADI) framework. (1) Communication and engagement refers to how stakeholders communicated with participants during the intervention period, including difficulties experienced staying connected with intervention activities during the lockdown. The study team and CHWs developed simple, plain-language guides designed to enhance digital literacy. (2) Intervention/research process describes intervention characteristics and challenges stakeholders faced in implementing components of the intervention during the lockdown. CHWs modified the health curriculum materials delivered remotely to support engagement in the intervention and health promotion. (3) community and implementation context pertains to the social and economic consequences of the lockdown and their effect on intervention implementation. CHWs and CBOs enhanced efforts to provide emotional/mental health support and connected community members to resources to address social needs. Study findings articulate a repository of recommendations for the adaptation of community-delivered programs in under-served communities during a time of public health crises.

A36 INVESTIGATING TYPE 1 REGULATORY T CELLS AS A THERAPY FOR INFLAMMATORY BOWEL DISEASE USING A MOUSE MODEL OF ACUTE INTESTINAL EPITHELIAL DAMAGE

Background

Inflammatory bowel disease (IBD) affects an estimated 270,000 people in Canada and is rapidly increasing in prevalence. All patients have relapsing disease, and a subset of individuals do not respond to current treatments. Further, there are no approved treatment options in Canada that reverse IBD-induced intestinal fibrosis. We have previously shown type 1 regulatory cells (Tr1s) are capable of suppressing inflammatory macrophages, promote barrier function of human intestinal epithelial cells, and induce differentiation of mucin-producing goblet cells. We hypothesize that Tr1 cells can prevent inflammatory damage and fibrosis in an mouse model of acute gut damage.

Purpose

We hypothesize that Tr1 cells can prevent inflammatory damage and fibrosis in an mouse model of gut damage. Here we evalute the therapeutic potential of Tr1 cells in an model of acute intestinal epithelial damage.

Method

Tr1 cells were isolated and expanded from CD4⁺ CD44^high FOXP3^- cells. Their phenotype was characterized by flow cytometry and cytokine secretion was measured via ELISA. WT B6 mice were given 2% DSS in H₂O for 7 days, followed by H₂O alone for 7 days. Prior to DSS treatment, mice were sub-lethally irradiated to facilitate engraftment, and given I.P. injections of PBS or 0.5 – 2 x 10⁶ Tr1 cells. Mice weights and health scores were recorded daily. At the endpoint, blood, spleen, and mesenteric lymph nodes were analyzed for Tr1 cell engraftment (or lack thereof) for each mouse. Complete white blood counts were performed for each mouse. Additionally, proximal, medial, and distal portions of the ileum were processed for histologic scoring.

Result(s)

Tr1 cells isolated from CD4⁺ CD44^high FOXP3^- cells produce high levels of IL-10 following stimulation (>35,000 pg/ml/1 x 10⁵ cells). Additionally, these cells express high levels of Tr1 markers CD49b and Lag-3. Optimization experiments indicated no significant differences between mice irradiated and given DSS and mice only given DSS (no irradiation). Our results suggest no significant differences in inflammatory cell infiltrate scores between control and Tr1 treated mice. However, gut architecture scores appeared to improve with increasing Tr1 doses. Further, weight change improved with Tr1 treatment, as compared to PBS controls. Interestingly, Tr1 treatment appeared to decrease total eosinophil and neutrophil counts from peripheral blood.

Conclusion(s)

Our initial findings indicate Tr1 adoptive transfer prior to acute damage via DSS improves gut damage and weight loss.

Prevalence of Substance Use Among Asian Sexual Minority Individuals in the United States, 2015-2020

Asian sexual minorities (SMs) are an under-researched population. SMs are at higher risk for substance use problems than heterosexuals, but little research exists specifically on Asians who are SM. This study compared the prevalence of substance use among Asian SMs and among adults by race/ethnicity and sexual identity in the US. Data were analyzed from participants in the 2015-2020 National Survey on Drug Use and Health, a nationally representative cross-sectional survey of non-institutionalized adults. Controlling for demographic characteristics, logistic regression models were used to estimate odds of substance use 1) among Asian adults by sexual identity (N = 11,079) and 2) all adults by race/ethnicity and sexual minority status (N = 223,971). Among Asians, compared to heterosexuals, identifying as gay/lesbian was associated with higher odds of past-month use of marijuana. Bisexual Asians were at higher odds of engaging in past-year prescription opioid misuse and having past-year alcohol use disorder (AUD). Compared to White heterosexuals, Asian SMs were at lower odds for past-month binge drinking and cocaine use, but not for past-month marijuana use and past-year AUD, marijuana use disorder, and prescription opioid misuse. More research is needed to understand these disparities and address sexual identity's role in substance use among Asians.

Intersectional discrimination and its impact on Asian American women's mental health: A mixed-methods scoping review

Introduction

Gendered racism against Asian American women has become an increasing public health threat in recent years. Although intersectional discrimination (i.e., co-occurring race- and gender-based discrimination) against Asian American women is not new, research on this topic is lacking. The present scoping review sought to explore how Asian American women report experiences of intersectional discrimination through a systematic examination of the current literature. We included studies that explicitly or implicitly discuss intersectional discrimination. We also aimed to identify indicators of psychological wellbeing and coping associated with these experiences.

Methods

Following PRISMA Guidelines for Systematic Scoping Reviews, database searches were conducted for peer-reviewed articles. A total of 1,476 studies were title- and abstract-screened by two independent reviewers. Then, 148 articles were full-text screened for eligibility.

Results

A final sample of 23 studies was identified (15 qualitative and 8 quantitative). Only nine of the included studies explicitly used an intersectional framework. Results from qualitative studies revealed that Asian American women experience intersectional discrimination through fetishization, the ascription of passivity, invalidation through lack of representation and pervasive white beauty ideals, and workplace tokenization and scrutiny. Study findings suggested that Asian American women experience these forms of intersectional discrimination across multiple levels of influence (i.e., internalized, interpersonal, institutional, structural). Findings from both qualitative and quantitative studies also indicated how discrimination, whether explicitly or implicitly intersectional, contributes to adverse mental health outcomes such as body shame, disordered eating, depression, and suicidality. Studies also touched on common coping mechanisms employed by Asian American women when facing or anticipating discrimination, such as avoidance, shifting, proactive coping, and leaning on networks of support. There was a lack of studies using quantitative assessments of intersectional discrimination. Also, most studies did not include disaggregated data by ethnicity, age, sexual identity, religion, socioeconomic status, immigration status, or skin color, all of which are likely to shape their experiences.

Discussion

Our scoping review highlights how the marginalization of Asian American women is an urgent threat to their mental wellbeing. These findings are discussed to inform future research, interventions, and policy changes that prevent racialized and gendered violence against Asian American women.

Factors Influencing Recovery and Well-Being Among Asian Survivors of International Criminal Sex Trafficking in an Urban U.S. City

Sex trafficking is serious form of gender-based violence that results in profound adverse health outcomes, yet one that is poorly understood. New York City is a major hub for sex trafficking, with a significant but unquantified number of victims originating from East Asian countries and trafficked via illicit massage businesses. Peer-reviewed studies among Asian survivors of international criminal sex trafficking do not exist. The aim of this study is to qualitatively examine the factors at various levels of influence that impact the recovery and reintegration process of Asian criminal sex trafficking survivors in the United States from the perspective of survivors and front-line service providers. The study was guided by community-based participatory research and trauma-informed approaches, leveraging a collaboration with a well-established service provider organization. Ten in-depth interviews were conducted between 2018 and 2019 with three Korean survivors and seven key informants who were anti-trafficking service providers working with East Asian clients. Data were analyzed using a grounded theory approach. Survivors and service providers vocalized factors at multiple levels that either facilitate or impede recovery and well-being. Levels of influence included structural (e.g., poverty/debt bondage, immigration status, limited English proficiency), cultural (e.g., fatalism, collectivism), institutional (e.g., lack of culturally appropriate, trauma-informed care), interpersonal (e.g., exploitation, social support), and individual (e.g., resilience). Stigma was a crosscutting factor that spanned all levels of influence. This study highlights the voices of survivors and front-line service providers to understand the lives of an under-researched population of Asian sex trafficking survivors. Ultimately, the root, structural causes of survivor marginalization need to be addressed, which stem from the intersection of class-, gender-, and race-related inequities. While survivors continue to experience exploitation and marginalization post-trafficking, they also carry an enormous amount of resilience that must be leveraged in their path to recovery from trauma.

1323 VOLUNTEER-LED ONLINE GROUP EXERCISE FOR OLDER ADULTS: A FEASIBILITY AND ACCEPTABILITY STUDY

Introduction

The health benefits of physical activity for older people are well recognised and include reduction in falls, improvement in frailty status and physical function. Nonetheless, physical inactivity remains a significant problem among older adults. This study aimed to determine the feasibility and acceptability of implementing online volunteer-led group exercise for community-dwelling older adults.

Methods

This pre-post mixed methods study was conducted among older adults attending community social clubs. Eligible participants were aged ≥ 65 years, able to walk independently, and able to provide written consent. The intervention consisted of a once weekly volunteer-led online group chair-based exercise. The primary outcomes were the feasibility and acceptability of the intervention. Secondary outcomes included physical activity levels measured using the Community Health Model Activities Program for Seniors (CHAMPS) questionnaire, functional status (Barthel Index), and health-related quality of life (EQ-5D-5L). Outcomes were measured at baseline and at 6 months. Trials registration: NCT04672200.

Results

Nineteen volunteers were recruited, 15 completed training and 9 were retained (mean age 68 years, 7 female). Thirty participants (mean age 77 years, 27 female) received the intervention and attended 54% (IQR 37-67) of exercise sessions. One minor adverse event was reported. Participants had no significant changes in secondary outcome measures, with a trend towards improvement in physical activity levels. The intervention was acceptable to volunteers, participants, and staff. The seated exercises were perceived as safe, manageable and enjoyable. Volunteers were relatable role models providing positive vicarious experiences that improved participants confidence to exercise within a friendly, non-judgmental environment. Technological issues, or reluctance to learn how to use technology were barriers to the intervention. The social interactions and sense of belonging motivated participation.

Conclusions

Trained volunteers can safely deliver online group exercise for community-dwelling older adults and the intervention was feasible and acceptable to older adults, volunteers and club staff.

Levels of physical activity and sitting time in women with infants, toddlers and preschoolers: a population-based cross-sectional study

OBJECTIVES

Insufficient physical activity (PA) and prolonged sitting time (ST) increase the risk of chronic disease and mortality. Caring for young children can potentially impact maternal PA and sedentary behaviours. The aims of this study were to explore the levels of PA and ST in women with young children (infants, toddlers and preschoolers) and sociodemographic and behavioural factors associated with these.

STUDY DESIGN

This was a population-based cross-sectional study.

METHODS

Survey 5 data collected in 2009 (n = 4290) of the 1973-1978 birth cohort of the Australian Longitudinal Study on Women's Health were used. Multiple linear and logistic regression models were used to examine associations.

RESULTS

In adjusted models, compared with women with preschoolers, women whose youngest child was an infant aged 0-6 months, aged >6-12 months or toddler had lower PA (-321.3 MET.min/week [95% confidence interval (CI) -416.2, -226.4], -147.9 MET.min/week [95% CI -237.6, -58.1] and -106.4 MET.min/week [95% CI -172.3, -40.5]). ST was higher in women whose youngest child was an infant aged 0-6 months (0.48 h/day; 95% CI 0.19, 0.77) but lower with infants aged >6-12 months (-0.33 h/day; 95% CI -0.60, -0.05) and toddlers (-0.40 h/day; 95% CI -0.60, -0.20) than in those with preschoolers. The findings were similar in the logistic model. Sociodemographic and behavioural factors such as occupation and marital status also influenced PA and ST.

CONCLUSIONS

Women with infants and toddlers have lower PA than women with preschoolers. Women are more likely to sit more in the first 6 months after childbirth. These findings can inform resources and intervention development to improve activity levels in women with young children through consideration of the age of the youngest child, sociodemographic and behavioural factors.

The long-term cardiac events after coronary bifurcation stenting with second-generation drug-eluting stents in elderly patients are comparable to those of younger patients

Background

Elderly patients undergoing percutaneous coronary intervention (PCI) generally have a high risk of adverse clinical outcomes. We investigated the long-term clinical impact of PCI on coronary bifurcation disease in elderly patients in Korea and Italy.

Methods

From the BIFURCAT (comBined Insights from the Unified RAIN and COBIS bifurcAtion regisTries) data, we evaluated 5,537 patients who underwent PCI for coronary bifurcation disease. The primary outcome was major adverse cardiac events (MACEs), defined as the composite of target vessel myocardial infarction, target lesion revascularisation, and stent thrombosis. Kaplan–Meier estimates and Cox proportional hazard models were used to compare elderly patients (aged ≥75 years) and younger patients (aged &lt;75 years).

Results

A total of 1,415 patients (26%) were aged ≥75 years. Elderly patients were more frequently female, had higher rates of hypertension and chronic kidney disease (CKD), and presented more frequently with left main (LM) disease. After a median follow-up of 2.1 years, MACEs were comparable between elderly and younger patients. In multivariable analysis, old age was not an independent predictor of MACEs (p=0.977). In elderly patients, CKD and LM disease were independent predictors of MACEs, whereas in younger patients, hypertension, diabetes, CKD, reduced left ventricular ejection fraction, LM disease, and two-stent strategy usage were independent predictors.

Conclusions

Elderly patients who underwent coronary bifurcation PCI with second-generation drug-eluting stents demonstrated similar clinical outcomes to those of younger patients. Both CKD and LM disease were independent predictors of MACEs, regardless of age after coronary bifurcation PCI.

The differential effects of antihypertensive drugs on central blood pressure: nebivolol versus telmisartan (ATD-CBP)

Background

Central blood pressure and central pulse pressure have a better correlation with the risk of cardiovascular disease compared to those of peripheral measurement. In a previous study, a second-generation beta-blocker showed poor CBP-lowering effects. However, the effect on CBP by third-generation beta-blockers is not fully elucidated. Thus, this randomised study investigated whether nebivolol-based hypertension treatment may confer advantages over telmisartan, an angiotensin II receptor-blocker, in reducing CBP.

Methods

This was a prospective, randomised, multicentre, open-label, controlled trial that evaluated 98 hypertensive patients. Patients received either nebivolol- (N=49) or telmisartan-based (N=49) treatment for hypertension for 12 weeks with a target BP of ≤140/80. The primary outcome was the difference in change from baseline central systolic BP (cSBP) after 12 weeks.

Results

There were no significant differences between the two groups in baseline central and peripheral SBP. The mean change in cSBP from baseline (ΔcSBP) was −17.2±3 mmHg for nebivolol group (P&lt;0.001) and −29.9±3 mmHg for telmisartan group (P&lt;0.001). The difference in ΔcSBP between the two groups was significant (12.7mmHg, 95% confidence interval [CI], 4.13 to 21.2; P=0.004). Peripheral SBP (pSBP) decreased less in nebivolol group compared to telmisartan group (−18.0±3 in nebivolol group vs. −26.3±3 in telmisartan group, P=0.032). After adjusting for reduction in pSBP, reduction in cSBP was higher in telmisartan group compared to nebivolol group, as shown by the ratio of changes in cSBP and pSBP (ΔcSBP/ΔpSBP; 0.67 for nebivolol group vs. 1.11 for telmisartan group, P=0.080), albeit without statistical significance.

Conclusions

Nebivolol-based hypertension treatment may have less potent CBP-lowering effects compared to telmisartan. However, larger-scale studies are warranted to further elaborate our findings.

Effect of an early invasive strategy based on time of symptom onset in patients with non-ST elevation myocardial infarction

Background

A limitation of the current guidelines of the timing of invasive coronary angiography (ICA) for patients with non-ST-segment elevation (NSTE) acute coronary syndrome is based on randomization time. So far, no study has reported the clinical outcomes of invasive strategy timing based on the time of symptom onset. Herein, we aimed to investigate the effect of invasive strategy timing from the time of symptom onset on the 3-year clinical outcomes of patients with NSTE myocardial infarction (MI).

Methods and results

Among 13,104 patients from the Korea Acute Myocardial Infarction Registry-National Institutes of Health, we evaluated 5,856 patients with NSTEMI. The patients were categorized according to symptom-to-catheter (StC) time (&lt;48 h and ≥48 h). The primary outcome was 3-year all-cause mortality, and the secondary outcome was a 3-year composite of all-cause mortality, recurrent MI, and hospitalization for heart failure. Overall, 3,919 (66.9%) patients were classified into the StC time &lt;48 h group. This group had lower all-cause mortality than the StC time ≥48 h group (7.3% vs. 13.4%, p&lt;0.001). The continuous association of StC time and risk of primary and secondary endpoints showed shorter StC time (reference: 48 h), and lower adjusted hazard ratio reduction was observed. In multivariable analysis, independent predictors of delayed ICA were older age, non-specific symptoms, no use of emergency medical services, no ST-segment deviation, chronic kidney disease, and Global Registry of Acute Coronary Events score &gt;140.

Conclusion

Early invasive strategy based on the StC time improves all-cause mortality in patients with NSTEMI.

Examining the effect of COVID-19 pandemic on exercise behavior and perceived academic stress among U.S. college students

Objective: The aim of this study was to capture the impact of COVID-19 on exercise behavior in U.S. college students. Exercise behaviors and perceived academic stress were examined from pre-COVID-19 (January-March 2020) and early-COVID-19 (April-July 2020) to continued-COVID-19 times (August-October 2020). Participants: One hundred and thirty-two participants completed the online questionnaires retrospectively. Methods: Two-way analyses of variance were used to examine exercise behaviors and academic stress perception over time between genders. Results: Participants spent much time in sedentary behavior and an increase in academic stress was evident in learning during the early-COVID-19 period. The time spent in sedentary behavior was reduced, but the stress involving coursework remained during the continued-COVID period. The impact of the COVID pandemic was observed to be universal across sex groups. Conclusions: Universities should consider how to support physical and mental health during lockdown and extended closure due to a pandemic.

Group B Streptococcus (GBS) colonisation is dynamic over time, whilst GBS capsular polysaccharides-specific antibody remains stable

Group B Streptococcus (GBS) is a leading cause of adverse pregnancy outcomes due to invasive infection. This study investigated longitudinal variation in GBS rectovaginal colonization, serum and vaginal GBS capsular polysaccharide (CPS)-specific antibody levels. Non-pregnant women were recruited in the UK and were sampled every 2 weeks over a 12-week period. GBS isolates were taken from recto-vaginal swabs and serotyped by polymerase chain reaction. Serum and vaginal immunoglobulin G (IgG) and nasal immunoglobulin A (IgA) specific to CPS were measured by Luminex, and total IgG/A by ELISA. Seventy women were enrolled, of median age 26. Out of the 66 participants who completed at least three visits: 14/47 (29.8%) women that were GBS negative at screening became positive in follow-up visits and 16/19 (84.2%) women who were GBS positive at screening became negative. There was 50% probability of becoming negative 36 days after the first positive swab. The rate of detectable GBS carriage fluctuated over time, although serum, vaginal, and nasal CPS-specific antibody levels remained constant. Levels of CPS-specific antibodies were higher in the serum of individuals colonized with GBS than in non-colonized, but similar in the vaginal and nasal mucosa. We found correlations between antibody levels in serum and the vaginal and nasal mucosa. Our study demonstrates the feasibility of elution methods to retrieve vaginal and nasal antibodies, and the optimization of immunoassays to measure GBS-CPS-specific antibodies. The difference between the dynamics of colonization and antibody response is interesting and further investigation is required for vaccine development.

957 THE USE OF IPADS AS PART OF PERSON CENTERED CARE IN A TEACHING HOSPITAL IN SINGAPORE

The elderly patients are currently the main occupants of acute hospital beds and this trend will likely increase as the world ages. The elderly patients with cognitive issues frequently have behavioural symptoms which may be challenging for the care staff to manage, especially the staff who have not been formally trained in Gerontology. The use of restraints for this group of vulnerable patients should be discouraged as restraints can cause harmful effects.

The use of iPads as a non pharmacological strategy for managing the behavioural symptoms among the elderly in-patients with cognitive issues was effective in reducing agitation, with an improvement in mood and sundown symptoms. The patients were actively and meaningfully engaged with their iPads during therapy.

The nursing staff too, benefited from iPads as a novel therapy for their elderly in-patients with cognitive issues in providing cognitive and social stimulations, which they had no time to provide for. While the patients showed improvement in their behavioural symptoms, the nurses’ stress levels reduced with improved self-reported job satisfaction.

Help seeking and mental health outcomes among South Asian young adult survivors of sexual violence in the New York State Region

BACKGROUND

Sexual violence is a growing issue faced across diverse South Asian American communities under the backdrop of a distinct religious and cultural environment that intersects with the ability to prevent and manage this public health crisis. There is also growing attention on sexual violence experienced by younger or second-generation South Asian Americans, although little is known on the prevalence of this violence and its impact on health outcomes. Using data from a community-driven sexual violence survey, this study describes the experience of sexual violence and related help seeking behaviors and mental health outcomes among 18-34-year-old South Asian Americans living near the New York (NY) State region.

METHODS

Participants were recruited via social media to participate in an anonymous survey developed in partnership with an advisory board of South Asian young adult representatives. Data was analyzed descriptively and through adjusted logistic regression models.

RESULTS

Overall, responses from 335 sexual assault survivors were analyzed. Types of assault experienced included no-contact (97.6%), contact (75.2%), rape attempts (50.2%), rape (44.6%), and multiple rape (19.6%). Many reported perpetrators were South Asian (65.1%) or family members (25.1%). Only 27.6% indicated they had reported assaults to authorities or received services. In adjusted analyses, odds of help seeking were higher among participants who were older (AOR:1.10, 95%CI:1.02-1.20), were a sexual minority (lesbian, gay, bisexual) (1.98, 1.05-3.71), had a family member as the perpetrator (1.85, 1.01-3.40), had lower disclosure stigma (1.66, 1.16-2.44), and experienced depression (2.16, 1.10-4.47). Odds of depression were higher among sexual minority participants and lower among those with higher sexual assault disclosure stigma (3.27, 1.61-7.16; 0.68, 0.50-0.93).

CONCLUSIONS

Findings call for greater targeted policy interventions to address the prevention of sexual violence among young South Asian Americans and greater focus on improving help seeking behaviors and improving mental health outcomes among survivors.

Experiences of researchers fulfilling VHA’s “fourth mission” during the COVID-19 pandemic

11059

Background: As the largest integrated healthcare system in the US, the Veterans Health Administration (VHA) is chartered “to serve as the primary backup for any health care services needed...in the event of war or national emergency” according to a 1982 Congressional Act. This mission was invoked during the COVID 19 pandemic to divert clinical and research resources, resulting in dramatic changes in the activities of investigators and research staff. This study uses established behavioral change frameworks to examine the experience of VHA cancer researchers during the pandemic. Methods: We conducted a mixed methods study on the effects of the pandemic on VHA researchers. We used an electronic questionnaire composed of Likert scale statements and open-ended questions, which was constructed using the 14 domains of the Theoretical Domains Framework (TDF) and the Capability, Opportunity, and Motivation (COM-B) model for behavior change. Likert scale statements were quantified and content analysis was performed on open ended responses. Results: The questionnaire was distributed electronically to 118 researchers participating in national VHA collaborations, with 42 responses (36%). Several significant themes and findings emerged. Only 36% of respondents did not feel that their research focus changed during the pandemic. (TDF: professional role and identity maps to COM-B Motivation). And 81% of respondents reported a diverse range of research interests (COM-B: M). Only 11 of 42 respondents (26%) reported prior experience with infectious disease research (TDF: skills maps to COM-B: C), and 31 of 42 (74%) agreed that they gained new research skills during the pandemic (COM-B: C). When asked to describe support structures helpful during the pandemic, 29% mentioned local supervisors, mentors and research staff (COM-B: C, M), 15% cited larger VHA organizations (COM-B: C) and 18% mentioned remote work abilities or telehealth (COM-B: O). Lack of timely communication from supervisors and remote work, particularly for individuals with caregiving responsibilities, were seen as limiting factors for research during the pandemic (COM-B: O). Although 83% of respondents agreed that they will be prepared to respond to future crises after COVID (COM-B: C), fewer than half (40%) of respondents felt professionally rewarded for pursuing research related to COVID, with 50% feeling neutral (COM-B: M). Conclusions: This study demonstrated the tremendous effects of the COVID 19 pandemic on research activities of VHA investigators. We identified perceptions of insufficient recognition and lack of professional advancement related to pandemic era research. Improving the structure of remote work and team communication represent high yield areas for improvement. It is essential to understand barriers and facilitators of crisis redeployment in the VHA, to make the transition effective and fulfilling for those carrying out the mission.

A Social Media-Based Diabetes Intervention for Low-Income Mandarin-Speaking Chinese Immigrants in the United States: Feasibility Study

BACKGROUND

Chinese immigrants bear a high diabetes burden and face significant barriers to accessing diabetes self-management education (DSME) and counseling programs.

OBJECTIVE

The goal of this study was to examine the feasibility and acceptability and to pilot test the potential efficacy of a social media-based DSME intervention among low-income Chinese immigrants with type 2 diabetes (T2D) in New York City.

METHODS

This was a single group pretest and posttest study in 30 Chinese immigrants with T2D. The intervention included 24 culturally and linguistically tailored DSME videos, focusing on diabetes education and behavioral counseling techniques. Over 12 weeks, participants received 2 brief videos each week via WeChat, a free social media app popular among Chinese immigrants. Primary outcomes included the feasibility and acceptability of the intervention. Feasibility was evaluated by recruitment processes, retention rates, and the video watch rate. Acceptability was assessed via a satisfaction survey at 3 months. Secondary outcomes, that is, hemoglobin A_1c (HbA_1c), self-efficacy, dietary intake, and physical activity, were measured at baseline, 3 months, and 6 months. Descriptive statistics and paired 2-sided t tests were used to summarize the baseline characteristics and changes before and after the intervention.

RESULTS

The sample population (N=30) consisted of mostly females (21/30, 70%) who were married (19/30, 63%), with limited English proficiency (30/30, 100%), and the mean age was 61 (SD 7) years. Most reported an annual household income of <US $25,000 (24/30, 80%) and a high school education or less (19/30, 63%). Thirty participants were recruited within 2 months (January and February 2020), and 97% (29/30) of the participants were retained at 6 months. A video watch rate of 92% (28/30) was achieved. The mean baseline HbA_1c level was 7.3% (SD 1.3%), and this level declined by 0.5% (95% CI -0.8% to -0.2%; P=.003) at 6 months. The mean satisfaction score was 9.9 (SD 0.6) out of 10, indicating a high level of satisfaction with the program. All strongly agreed or agreed that they preferred this video-based DSME over face-to-face visits. Compared to baseline, there were significant improvements in self-efficacy, dietary, and physical activity behaviors at 6 months.

CONCLUSIONS

This pilot study demonstrated that a social media-based DSME intervention is feasible, acceptable, and potentially efficacious in a low-income Chinese immigrant population with T2D. Future studies need to examine the efficacy in an adequately powered clinical trial.

Sexual violence among LGB+ South Asian Americans: Findings from a community survey

Lesbian, gay, bisexual, and other sexual minority (LGB+) South Asian Americans represent a disproportionately underserved and often invisible community in the United States. While issues of sexual violence have been documented in the South Asian American community, little is known on its impact among LGB+ individuals. This study explores the experience of sexual violence, related attitudes, and mental health outcomes among LGB+ South Asian Americans. A community-informed online survey of 18–34-year-old South Asian Americans living near the New York State region, recruited from online social media platforms, was conducted. Study design, implementation, and evaluation occurred in partnership with an advisory board of South Asian young adult representatives; data was analyzed both descriptively and through multivariable logistic regression models. Of the 385 participants who reported their sexuality, LGB+ participants comprised 24.1% (n = 93) of the sample. LGB+ participants were more likely to have experienced rape multiple times (17.2% vs. 9.6%) in bivariate analyses, and higher odds of depression (AOR:3.47, 95%CI:1.61–8.17) in adjusted analyses. Overall, LGB+ South Asian Americans displayed a disproportionate burden of sexual violence and depression. Findings identify policy and research pathways to address sexual violence among LGB+ South Asians.

OnBehalf

Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients with Functional Mitral Regurgitation (COAPT)

Background

Prior studies suggest tricuspid regurgitation (TR) diminishes/resolves following mitral valve surgery and thus do not require treatment and may not influence outcomes.

Purpose

  We sought to evaluate the change in TR (ΔTR) and its association with outcomes after transcatheter edge-to-edge repair (TEER) compared with guideline-directed medical therapy (GDMT) in the COAPT trial.

Methods

Patients from the COAPT trial with echo core lab TR assessment at baseline and 30-day follow-up (n = 504) were included and divided into 2 groups: those whose TR worsened (ΔTR-INC) and those with no change or improvement in TR (ΔTR-SAME/DEC).  Two-year composite endpoints of death or heart failure hospitalization (HFH) and the individual components were analyzed, after excluding events occurring within the first 30 days.

Results

ΔTR-SAME/DEC occurred in 430 pts (228 TEER, 202 GDMT) while ΔTR-INC was noted in 74 pts (38 TEER, 36 GDMT) (Figure 1A). From 30 days to 2 years, ΔTR-INC pts had a higher rate of the composite outcome of death or HFH compared with ΔTR-SAME/DEC (p = 0.006, Figure 1B). Both 2-year death (HR 1.52, 95% CI 1.01-2.27; p = 0.04) and HFH (HR 1.52, 95% CI 1.04-2.22; p = 0.03) were associated with ΔTR-INC. Assessed by treatment group (Figure 1C and 1D), the relationship between ΔTR-INC and composite death or HFH was significant in GDMT alone pts (HR 1.86, 95% CI 1.21-2.86) but not in TEER pts (HR 1.33, 95% CI 0.79-2.23), although interaction testing demonstrated consistency between the two treatments  (Pint = 0.31). 

Conclusions

Worsening TR at 30 days occurred in ∼15% of pts in the COAPT trial whether they were treated with TEER or GDMT alone. DTRINC was associated with increased death and HFH during 2-year follow-up. Abstract Figure 1

HIV, Tuberculosis, and Food Insecurity in Africa—A Syndemics-Based Scoping Review

The double burden of HIV/AIDS and tuberculosis (TB), coupled with endemic and problematic food insecurity in Africa, can interact to negatively impact health outcomes, creating a syndemic. For people living with HIV/AIDS (PWH), food insecurity is a significant risk factor for acquiring TB due to the strong nutritional influences and co-occurring contextual barriers. We aim to synthesize evidence on the syndemic relationship between HIV/AIDS and TB co-infection and food insecurity in Africa. We conducted a scoping review of studies in Africa that included co-infected adults and children, with evidence of food insecurity, characterized by insufficient to lack of access to macronutrients. We sourced information from major public health databases. Qualitative, narrative analysis was used to synthesize the data. Of 1072 articles screened, 18 articles discussed the syndemic effect of HIV/AIDS and TB co-infection and food insecurity. Reporting of food insecurity was inconsistent, however, five studies estimated it using a validated scale. Food insecure co-infected adults had an average BMI of 16.5–18.5 kg/m². Negative outcomes include death (n = 6 studies), depression (n = 1 study), treatment non-adherence, weight loss, wasting, opportunistic infections, TB-related lung diseases, lethargy. Food insecurity was a precursor to co-infection, especially with the onset/increased incidence of TB in PWH. Economic, social, and facility-level factors influenced the negative impact of food insecurity on the health of co-infected individuals. Nutritional support, economic relief, and psychosocial support minimized the harmful effects of food insecurity in HIV–TB populations. Interventions that tackle one or more components of a syndemic interaction can have beneficial effects on health outcomes and experiences of PWH with TB in Africa.

Community Recruitment of Asian, Latino and African American Older Adults With Depression Symptoms During COVID-19

Recruitment and engagement of racial/ethnic minority older adults in clinical trials is crucial to expand implementation of evidence-based interventions for disability prevention. Public Health measures to counteract COVID-19 pandemic have increased the challenges on reaching this population. This study seeks to comprehensively evaluate a set of recruitment strategies to enroll Latino, Asian and African American older adults with symptoms of depression and anxiety during the first year of a randomized clinical trial. A partnership of three academic sites across the U.S. (NYC, MA and PR) involving several collaborations with community agencies recruited racial/ethnic minority older adults using different strategies involving bilingual interviewers calling from hospital research dataset and community agencies’ list of clients, referrals from primary care providers or psychotherapy waitlist. In this presentation we will report various recruitment and retention data including individual and organizational predictors of successful recruitment as well as challenges across all three sites.

Development of postbiotics by whey bioconversion with Enterococcus faecalis M157 KACC81148BP and Lactococcus lactis CAU2013 KACC81152BP for treating periodontal disease and improving gut health

This study developed postbiotics with whey bioconversion product produced by Enterococcus faecalis M157 KACC 81148BP, and mixed whey bioconversion products produced by E. faecalis M157 KACC 81148BP and Lactococcus lactis ssp. lactis CAU2013 KACC 81152BP to alleviate periodontitis (PD) and to improve gut health. The powdered whey bioconversion product (EF) produced by E. faecalis M157 KACC 81148BP, mixed whey bioconversion products (EF+LL) from E. faecalis M157 KACC 81148BP and L. lactis CAU2013 KACC 81152BP, and phosphate-buffered saline (PBS; control) were administered orally to PD-induced rats for 8 wk. Infiltration of inflammatory cells and epithelial proliferation in periodontal tissue were found in control, but the lesions were reduced in PD+EF group (administration of EF to PD-induced rats), and no lesions were observed in PD+EF+LL group (administration of EF+LL to PD-induced rats). The bone loss volumes in PD+EF and PD+EF+LL groups were lower than in control. Cytokine production levels related to inflammation were lower and antioxidative stress markers were higher in PD+EF and PD+EF+LL groups than in control for both periodontal tissue and gut. The ratios of Lactobacillus spp. in gut microbiome of PD+EF and PD+EF+LL groups were higher than in control. These results indicate that the whey bioconversion product produced by E. faecalis M157 KACC 81148BP, and mixed whey bioconversion products produced by E. faecalis M157 KACC 81148BP and L. lactis CAU2013 KACC 81152BP are effective on relieving periodontitis and improving the gut health.
