Mitolnc controls cardiac BCAA metabolism and heart hypertrophy by allosteric activation of BCKDH.

Enzyme activity is determined by various different mechanisms, including posttranslational modifications and allosteric regulation. Allosteric activators are often metabolites but other molecules serve similar functions. So far, examples of long non-coding RNAs (lncRNAs) acting as allosteric activators of enzyme activity are missing. Here, we describe the function of mitolnc in cardiomyocytes, a nuclear encoded long non-coding RNA, located in mitochondria and directly interacting with the branched-chain ketoacid dehydrogenase (BCKDH) complex to increase its activity. The BCKDH complex is critical for branched-chain amino acid catabolism (BCAAs). Inactivation of mitolnc in mice reduces BCKDH complex activity, resulting in accumulation of BCAAs in the heart and cardiac hypertrophy via enhanced mTOR signaling. We found that mitolnc allosterically activates the BCKDH complex, independent of phosphorylation. Mitolnc-mediated regulation of the BCKDH complex constitutes an important additional layer to regulate the BCKDH complex in a tissue-specific manner, evading direct coupling of BCAA metabolism to ACLY-dependent lipogenesis.

Health equity in action: using community-engaged research to update an intervention promoting a healthy home food environment to Black/African American families.

PURPOSE: Describe the method for conducting community-engaged research to identify needed changes for an existing evidence-based intervention, and prepare it for implementation in a community setting within the Dan L Duncan Comprehensive Cancer Center catchment area in an effort to achieve more equitable outcomes in diet-related disease risk factors. METHODS: The intervention, Family Eats, was developed over 10 years ago. It works directly with parents of Black/African American 9-12 year old children to create a healthy home food environment to support prevention of obesity and related cancers. Data collection with community stakeholders occurred through a series of  Community Advisory Board (CAB) meetings guided by the Delphi Technique, an iterative approach for gaining group consensus on a topic. RESULTS: Key information on needed changes and potential implementation strategies were identified. Perceived level of engagement among CAB members was high overall and in terms of both quantity and quality. CONCLUSION: The Delphi Technique shows promise as a method for conducting community-engaged research that promotes engagement and identifies key information needed to adapt and implement an existing intervention in a community setting.

Self-Sampling for Human Papillomavirus Testing: Acceptability in a U.S. Safety Net Health System.

INTRODUCTION: Self-sampling for human papillomavirus testing is increasingly recognized as a strategy to expand cervical cancer screening access and utilization. Acceptability is a key determinant of uptake. This study assesses the acceptability of and experiences with mailed self-sampling kits for human papillomavirus testing among underscreened patients in a safety net health system. METHODS: A nested telephone survey was administered between 2021 and 2023 to a sample (n=272) of the 2,268 participants enrolled in the Prospective Evaluation of Self-Testing to Increase Screening trial. Trial participants include patients of a safety net health system aged 30-65 years who were not up to date on screening. Participants were asked about barriers to provider-performed screening. Kit users and nonusers were asked about their experiences. RESULTS: Prevalent barriers to provider-performed screening included perceived discomfort of pelvic examination (69.4%), being uncomfortable with male providers (65.4%), and embarrassment (57.0%). Among participants who reported using the mailed kit (n=164), most reported good experiences (84.8%). Most reported self-sampling as more/equally convenient (89.0%), less/equally embarrassing (99.4%), and less/equally stressful (95.7%) than provider-performed screening. Among kit nonusers (n=43), reasons for not using the kit included forgetting about it (76.7%), preferring provider-performed screening (76.7%), and fearing cancer (67.4%). CONCLUSIONS: Prospective Evaluation of Self-Testing to Increase Screening trial participants generally had a positive experience with self-sampling for human papillomavirus testing. Increased comfort and reduced embarrassment/anxiety with self-sampling are relevant attributes because these were the most prevalent reported barriers to provider-performed screening. High acceptability suggests potentially high uptake when self-sampling for human papillomavirus testing receives regulatory approval and is available in safety net health systems.

Using Culturally Adapted Theater Outreach to Promote Cancer Screening Among Medically Underserved Minority Communities.

Black, Hispanic, and Asian individuals, the three largest US racial/ethnic minorities, continue to suffer disproportionately from breast, cervical, and colon cancers largely because cancer screening continues to be underutilized even after decades of availability. This study examined the utility of theoretically grounded and culturally adapted in-person theater monologues aimed at promoting early detection screening among the three highest population racial/ethnic groups in Harris County, Houston, TX. Nine monologues were created to promote cancer screening and early detection for breast, cervical, and colorectal cancers in three different languages (English, Spanish, Vietnamese) and targeting underserved Black, Hispanic, and Vietnamese adult Harris County residents. From January 2014 to March 2020, 265 live monologue outreach events were held with 110 focused on prevention and screening for breast cancer, 75 for colorectal cancer, and 80 for cervical cancer. A total of 5989 individuals attended these outreach events and 86.3% completed the post-performance evaluation survey. Overall for all monologues, 6.6% of participants reported a positive change in their intent to screen from 75.7 to 82.3% after intervention (p < 0.001) and audience member scores on knowledge questions for all three cancers were mostly positive. Importantly, early detection questions for all three cancers were over 90% correct for all respondents, and well over 70% for the various groups. The findings revealed opportunities for improving monologue content to cultivate cancer early detection and screening knowledge. Results suggest that a theater-based approach may be an effective strategy to disseminate cancer screening education, improve knowledge, and increase intent to obtain screening among medically underserved communities.

Gender Differences in Self-Efficacy for Diabetes Self-Management Among Hispanics: The Mediating Role of Perceived Support and Depressive Symptoms.

PURPOSE: The purpose of this study is to examine the extent to which perceived support and depressive symptoms might interfere with Hispanic patients' ability to manage their diabetes and whether these effects vary by gender. METHODS: Data were collected from a cohort of 232 Hispanic men and women with type 2 diabetes mellitus (T2DM). Conditional process analysis was used to test a moderated mediation model of the time-lagged processes associating gender, diabetes support, and depressive symptoms with reported self-efficacy after 3 months. RESULTS: Increased depressive symptoms were associated with lower self-efficacy, but the conditional effects varied among men and women. The index of moderated mediation was significant, indicating that among women, the indirect effect of depressive symptoms on self-efficacy was contingent on lower levels of perceived support. Among men, increased depressive symptoms were directly associated with declines in self-efficacy and were not conditional on perceived support. CONCLUSIONS: Results of the study have important implications for gender health equity. Mental health screening and an assessment of support needs may be important for determining appropriate complementary therapies when treating Hispanic women with chronic conditions such as diabetes. Attention to possible differences in gender-specific mental health needs could lead to improved self-management, better glycemic control, and more equitable health outcomes.

The Texas collaborative center for hepatocellular cancer: Reducing liver cancer mortality in Texas through coordination, collaboration and advocacy.

Texas has the highest age-adjusted incidence rate of hepatocellular carcinoma (HCC) in the United States. To address cancer prevention and early detection through research, Cancer Prevention and Research Institute of Texas (CPRIT) has funded the Texas Collaborative Center for Hepatocellular Cancer (TeCH) to facilitate liver cancer research, education and advocacy activities. This paper describes the organizational structure, program measures, the actions completed and future plans of TeCH. This center is comprised of several cores and committees including the Administrative Core, Steering Committee, Data and Biospecimen Core, Scientific Committee, Clinical Network Committee, and the Community Outreach Committee. Each core and committee provide its own level of connectivity and necessary research support. We have developed and published a TeCH Framework, a conceptual model designed for improving primary and secondary prevention of HCC. TeCH and its committees facilitate connections and collaborations among HCC researchers and clinicians, healthcare leaders, biotechnology companies and the public to reduce liver cancer mortality in Texas by 2030.

Human Papillomavirus Vaccinations During the COVID-19 Pandemic in Middle Schools in the Rio Grande Valley of Texas.

This quasi-experimental study (a community-based, physician-led human papillomavirus [HPV] education campaign and school-based vaccination program) followed 6481 students at eight Pharr-San Juan-Alamo Independent School District (Rio Grande Valley, Texas) middle schools between August 2016 and March 2021. We describe the successes and challenges experienced during the COVID-19 pandemic. HPV vaccine initiation and completion rates increased 1.29-fold and 1.47-fold, respectively, between June 2019 and March 2021. Between March 2020 and March 2021, 268 HPV vaccine doses were provided through 24 school-based interventions. Our program continued successes seen in increasing HPV vaccination rates and reducing possible HPV-associated cancers.

Preferred Strategies for Delivering Health Information to Patients With Musculoskeletal Disorders: A Qualitative Study.

BACKGROUND: Patients' information needs may differ from what their care providers may perceive to be the patients' needs. This discordance needs to be recognized and addressed. OBJECTIVE: We conducted a qualitative study to explore the perceptions of patients with selected musculoskeletal disorders and those of rheumatologists, on their preferred strategies for delivery of disease management information. METHODS: Fifty-two patients diagnosed with either rheumatoid arthritis, knee osteoarthritis, or osteoporosis took part in 6 focus groups and 18 individual semistructured interviews. In addition, 11 rheumatologists participated in 2 focus groups and 4 semistructured individual interviews. Data were explored by thematic content analysis. Perceived preferences were identified and compared between patients and rheumatologists regarding (a) media, (b) setting, (c) messengers, and (d) key message content. RESULTS: Patients' preferred media for disease management information were electronic (television and videos delivered as digital optical discs or the Internet), group instruction, and printed material. Patients preferred the information to be delivered in the setting of their homes, doctor's offices, or clinic waiting areas by the rheumatologists and patients with disease experience, addressing healthy lifestyle changes, medication adherence, and consequences of noncompliance. For rheumatologists, the perceived preference for information delivery was through printed material (brochures, booklets, and pamphlets) delivered in waiting areas by nurses and physicians, addressing nature of the disease, complications, and treatment adverse effects. CONCLUSIONS: Provider perspectives on strategies for education may differ from those of patients. Our findings highlight the need for considering different stakeholder perspectives in designing educational tools and decision support materials for patients with chronic diseases. TAKEHOME MESSAGE: Rheumatologists' preferences on strategies for education (mode of delivery, delivery setting, messengers, and topics) differ from those of patients. For example, patients want to learn about lifestyle changes and consequences of compliance versus noncompliance, whereas rheumatologists considered more important for patients to understand their disease, treatment adverse effects, and consequences of noncompliance.

Psychosocial Contributors to Depressive Symptoms in Hispanic Patients With Type 2 Diabetes.

PURPOSE: The purpose of this study is to identify psychosocial factors associated with depressive symptoms in Hispanic patients with diabetes and explore the extent to which their effects may vary by gender and acculturation. METHODS: The authors completed a secondary analysis of data from 247 Hispanic adults with type 2 diabetes. Gender and language groups were compared using chi-square and t tests. Hierarchical multiple regression was used to examine associations of depressive symptoms with perceived support, diabetes-related distress, and social and personal factors. RESULTS: Women reported less support than men. English speakers reported more depressive symptoms than Spanish speakers. When adjusting for age, gender, and acculturation, psychosocial factors significantly associated with depressive symptoms included less support received, greater emotional burden, and less ability to socialize or pursue normal activities because of diabetes. CONCLUSIONS: Social support provided by family among less acculturated Hispanics may play an important role in reducing emotional burden and lowering the risk of comorbid depression. The quality of interpersonal relationships and the ability to continue normal activities may also be important. More acculturated Hispanic women with diabetes may be at greater risk for comorbid depression and worse health outcomes. Screening for depression and assessment of support needs is warranted for Hispanic women.

Human papillomavirus awareness among foreign- and US-born Hispanics, United States, 2017-2018.

INTRODUCTION: Human papillomavirus (HPV) and HPV vaccine knowledge and awareness are known to be lower among Hispanics compared to non-Hispanic whites. However, Hispanics in the US are a non-homogenous population, with significant differences by nativity, particularly between the US-and foreign-born individuals. We examined HPV and HPV vaccine awareness among foreign-born Hispanics, US-born Hispanics, and US-born non-Hispanic whites. METHODS: We analyzed data from the Health Information National Trends Survey (HINTS) 5, cycles 1 (2017) and 2 (2018), the most recent HINTS datasets including nativity information. We used descriptive statistics and multivariable regression to compare awareness of HPV and the HPV vaccine among ethnicity/nativity subgroups. RESULTS: Over 50% of foreign-born Hispanics had not heard of HPV, compared to 32% of US-born Hispanics (P < 0.01) and 33% of non-Hispanic whites (p < 0.01). Lack of HPV vaccine awareness among foreign-born Hispanics was not significantly different from US-born Hispanics (52% vs. 44%, p = 0.12), but was significantly lower compared to non-Hispanic whites (52% vs. 32%, p < 0.01). In multivariable analyses, non-Hispanic whites had over twice the odds of having heard of HPV than foreign-born Hispanics (p < 0.05), while US-born Hispanics had 75% higher odds (p < 0.05). Regarding HPV awareness, non-Hispanic whites had 95% higher odds of having heard of the HPV vaccine than foreign-born Hispanics (p < 0.05), while differences between US and foreign-born Hispanics were not significant. CONCLUSION: There are significant nativity-related differences in HPV and HPV vaccine awareness and knowledge among US-born Hispanics. Over 50% of foreign-born Hispanic adults are unaware of HPV and the HPV vaccine.

Adolescent electronic cigarette counselling: knowledge, attitudes and perceived barriers among clinical staff in a primary care setting.

OBJECTIVE: To assess knowledge, attitudes, and perceived barriers (KAP) regarding e-cigarette use counselling among adolescent healthcare clinical staff in an urban system, and to compare results between providers and rooming staff. METHODS: Primary care clinical staff (n = 169) completed an anonymous survey. Descriptive statistics and Chi-square tests were used to summarize data and compare KAP between medical providers and rooming staff. RESULTS: Staff wanted to learn more about e-cigarettes (87.6%). The most common knowledge deficits were how to use the 5As + 5Rs model for tobacco cessation counselling (66.7%) and the chemical content of e-liquids (55.4%), with no differences across groups. Overall, 58% of providers expressed confidence in their ability to talk with adolescent patients about e-cigarette use. The most common barriers to counselling were low knowledge about e-cigarettes (74.0%) and how to refer adolescent patients for cessation support (43.8%). CONCLUSIONS: Provider and rooming staff expressed similar educational needs surrounding e-cigarettes, counselling, and treatment for adolescent patients. Clinical staff expressed confidence in their ability to affect change. There were no differences in the identified knowledge gaps or barriers to care between rooming staff and providers, suggesting that the same educational format can be used to target both groups.

Incomplete Records as a Leading Cause of Missed Opportunity for Human Papillomavirus Vaccine Initiation in a Safety Net Health System.

OBJECTIVE: The goal of this study was to categorize reasons behind missed opportunities for human papillomavirus (HPV) vaccine initiation in an under-resourced population and to identify associated patient and clinic characteristics. METHODS: Manual chart review was performed for patients aged 11 to 18 years who visited a primary care clinic in a health system in Texas, USA between 06/01/18 and 08/31/18 and were due for an initial HPV vaccine dose but did not receive it. Reasons for HPV vaccine noninitiation were categorized as follows: incomplete immunization record, no documentation of discussion (no documentation that the HPV vaccine was offered or ordered), refusal, staff/provider error, and medical. Multinomial logistic regression was used to examine factors associated with each category. RESULTS: Of 4467 adolescents seen in the study period, 575 (12.9%) were due for the first dose of HPV vaccine but did not receive it. The most common reason for noninitiation was incomplete immunization record (37%), followed by no documentation of discussion (24%), refusal (20%), staff/provider error (15%), and medical (4%). The highest odds of incomplete immunization were among older adolescents. The highest odds of no documentation of discussion were during sick visits. The highest odds of staff/provider error were among patients with commercial insurance. The lowest odds of refusal were in patients with county/indigent insurance. CONCLUSIONS: The most common reason for missed opportunity visits for HPV vaccine initiation was lack of adequate immunization records. Our study highlights the importance of immunization record access and bidirectional reporting as important targets for future interventions.

Randomized Controlled Trial of Patient Education Tools for Patients With Rheumatoid Arthritis.

OBJECTIVE: The present study was undertaken to evaluate the efficacy of 2 educational tools for patients with rheumatoid arthritis (RA) by comparing a newly developed video tool, including storylines and testimonials, combined with a written booklet to the same written booklet alone. METHODS: We conducted a randomized controlled trial. Our primary outcome was disease knowledge. Secondary outcomes were decisional conflict, self-efficacy, effective health care management, and satisfaction. Outcomes were measured before and after reviewing the materials, and 3 and 6 months later. Linear mixed-effects models were performed to evaluate changes over time. RESULTS: In total, 221 participants received an educational video and booklet (n = 111) or a booklet alone (n = 110). The mean age was 50.8 years, mean disease duration was 4.8 years, 85% were female, and 24% had limited health literacy levels. Within groups, most outcomes improved between baseline and follow-up, but there were no statistically significant differences across groups. Patients receiving the video and booklet were more likely than those receiving the booklet alone to rate the presentation as excellent for providing information about the impact of RA, medication options, evidence about medications, benefits of medication, and self-care options. Factors significantly associated with greater improvements in knowledge and decisional conflict from baseline to 6 months included limited health literacy, lower educational level, and shorter disease duration. CONCLUSION: Regardless of the delivery method, outcomes were improved up to 6 months after educational materials were delivered. Our findings support the implementation of self-administered educational materials in clinical settings, as they can result in sustained improvements in disease knowledge and decisional conflict.

Análisis de oportunidades perdidas y barreras de vacunación en menores de 7 años que visitan los centros de salud en la ciudad de Azul, año 2022 / Analysis of missed opportunities and vaccination barriers in children under 7 years of age who visit health centers in the city of Azul, year 2022

INTRODUCCIÓN La vacunación universal ha sido una de las estrategias más efectivas en Salud Pública para disminuir la mortalidad infantil. Los problemas de accesibilidad, la complejidad de los esquemas actuales, el miedo a los efectos adversos, la falta de conocimiento por parte de los médicos sobre vacunas y las oportunidades pérdidas de vacunación (OPV) se suman en este tiempo a los asociados a medidas extraordinarias tomadas en el contexto de la pandemia por el virus SARS-Cov2. OBJETIVOS Identificar los principales factores del sistema de salud y del individuo asociados OPV que contribuyen en el descenso de coberturas de vacunas del esquema nacional de vacunación en población menores de 7 años de la ciudad de Azul en el contexto de pandemia. MÉTODOS Se utilizaron las encuestas provistas por la Organización mundial de la salud (OMS) para análisis de OPV. Las mismas fueron administradas a la salida de todos los establecimientos de salud que cuentan con vacunatorios a cuidadores de menores de 7 años, y encuestas autoadministradas sobre conocimiento, actitudes y prácticas al personal de salud dedichos centros. Muestra no probabilística. Las OPV se calcularon en base a las libretas de vacunación o sus registros locales de vacunación según el esquema nacional de vacunación. RESULTADOS Se realizaron 184 encuestas a cuidadores de niños menores de 7 años a la salida de establecimientos de primer y segundo nivel de la ciudad de Azul. La proporción de encuestas para el nivel primario de atención fue de 63,04% (IC 55,63-70,03%) y para el nivel secundario 36,96% (IC 29,97-44,37). Del total de elegibles el 15,43% (IC 10,24-21,93) presentaron al menos una OPV. Al indagar el motivo de no vacunación en dicha población el24% (9,36-45,13) se perdió porque no le preguntaron, otro 24% (9,36-45,13) por cuestiones asociadas a la logística del servicio de vacunación. Los 25 niños elegibles no vacunados representaron un total de 59 OPDV, siendo la 4 dosis de Pentavalente el 16,9% de las mismas (IC 9,47-28,46). Se encuestaron 15 de 34 trabajadores de la salud, hallándose en un 66,67% (38,38-88,18) barreras de conocimiento y un 46,67 (21,27-73,41) presentaron barreras de actitud y prácticas. DISCUSIÓN la herramienta de OPV-OMS permitió caracterizar los motivos potenciales de OPV de nuestra ciudad, siendo la pobre coordinación entre las visitas al sistema de salud y la vacunación incompleta durante las visitas al vacunatorio dos puntos a mejorar.

Mailed self-sample HPV testing kits to improve cervical cancer screening in a safety net health system: protocol for a hybrid effectiveness-implementation randomized controlled trial.

BACKGROUND: Almost 20% of U.S. women remain at risk for cervical cancer due to their inability or unwillingness to participate in periodic clinic-based screening. Self-sampling has been shown to be an effective strategy for screening women for high-risk human papillomavirus (HR-HPV) infection in specific contexts. However, its effectiveness among medically underserved women in safety net health systems has not been evaluated. Furthermore, it is also unclear whether implementation strategies such as patient navigation can be used to improve the success of self-sample screening programs by addressing patient-level barriers to participation. METHODS/DESIGN: The Prospective Evaluation of Self-Testing to Increase Screening (PRESTIS) trial is a hybrid type 2 effectiveness-implementation pragmatic randomized controlled trial of mailed self-sample HPV testing. The aim is to assess the effectiveness of mailed self-sample HPV testing kits to improve cervical cancer screening participation among patients in a safety net health system who are overdue for clinic-based screening, while simultaneously assessing patient navigation as an implementation strategy. Its setting is a large, urban safety net health system that serves a predominantly racial/ethnic minority patient population. The trial targets recruitment of 2268 participants randomized to telephone recall (enhanced usual care, n = 756), telephone recall with mailed self-sample HPV testing kit (intervention, n = 756), or telephone recall with mailed self-sample HPV testing kit and patient navigation (intervention + implementation strategy, n = 756). The primary effectiveness outcome is completion of primary screening, defined as completion and return of mailed self-sample kit or completion of a clinic-based Pap test. Secondary effectiveness outcomes are predictors of screening and attendance for clinical follow-up among women with a positive screening test. Implementation outcomes are reach, acceptability, fidelity, adaptations, and cost-effectiveness. DISCUSSION: Hybrid designs are needed to evaluate the clinical effectiveness of self-sample HPV testing in specific populations and settings, while incorporating and evaluating methods to optimize its real-world implementation. The current manuscript describes the rationale and design of a hybrid type 2 trial of self-sample HPV testing in a safety net health system. Trial findings are expected to provide meaningful data to inform screening strategies to ultimately realize the global goal of eliminating cervical cancer.
