RESUMO

BACKGROUND & AIMS: Patient navigation interventions can improve health outcomes in underserved, low-income, and racial and ethnic minority groups, who often experience health disparities. We examined the effectiveness of patient navigation to improve linkage to hepatitis C virus (HCV) treatment receipt in a socioeconomically disadvantaged, racially diverse patient population. METHODS: We performed a pre-post analysis evaluating the effectiveness of a patient navigation program among baby boomers who tested positive for HCV in a safety-net health system. The usual care group (June 2013 to May 2015) and patient navigation group (January 2016 to December 2017) were balanced using a stabilized inverse probability of treatment weighting approach. We used logistic regression analyses to evaluate associations between patient navigation and linkage to care for HCV treatment evaluation, treatment initiation, and sustained virologic response. RESULTS: Among 1353 patients (62% black, 61% uninsured, 16% homeless), 769 were in the usual care group, and 584 were in the patient navigation group. The patient navigation group had significantly higher odds of linkage to care (odds ratio [OR], 3.7; 95% confidence interval [CI], 2.9-4.8) and treatment initiation (OR, 3.2; 95% CI, 2.3-4.2) within 6 months. The patient navigation group continued to have increased linkage to care (OR, 3.4; 95% CI, 2.7-4.3) and treatment initiation (OR 2.3; 95% CI, 1.7-3.0) at 12 months. However, there was no significant difference in sustained virologic response between the groups (86.9% vs 86.1%; P = .78). CONCLUSIONS: Patient navigation was associated with significantly increased linkage to care and treatment initiation among patients with HCV infection. Patient navigation programs can be used to promote HCV elimination among traditionally difficult-to-reach patient populations.

RESUMO

BACKGROUND: South Texas Latinas experience higher cervical cancer incidence and mortality compared to Latinas nationwide. Despite the availability of effective human papillomavirus vaccines, South Texas Latino/a adolescents sub-optimally complete the series. Research shows provider recommendation strongly predicts vaccine uptake, but minority adolescents are less likely to report that their provider recommended the vaccine and series completion. There is also scant information on the HPV vaccine administration process in clinic practices providing vaccination services to Latino adolescents with limited access to healthcare resources. The purpose of the study was to describe providers' experience with administering the HPV vaccine to Latino/a patients in their practices. METHODS: The study used qualitative description to describe the experience of 15 South Texas healthcare providers (doctors and nurses) with the process of HPV vaccine administration in their practices. We conducted open ended, audio-recorded interviews, which were subsequently transcribed verbatim and uploaded into Atlas.(ti) 7.0 for analysis. The interviews yielded detailed descriptions of barriers and facilitators that could potentially impact HPV vaccine uptake. RESULTS: Providers identified parental exposure to provider recommendation as enhancing HPV acceptance and existing policies and implementation of evidence-based practices as facilitators of HPV vaccine uptake. Barriers ranged from parental fears of adolescent sexual activity and potential vaccine side effects to lack of transportation and the cost of the vaccine. CONCLUSION: These findings reflect barriers and facilitators to administering the HPV vaccine previously identified and also highlight issues unique to the situation among Latinos in South Texas. Implications include the need to design and implement efforts to improve provider-parent communication and enhance parental and adolescent patients' understanding of and confidence in the HPV vaccine. Furthermore, policy changes are needed to rectify organizational/structural challenges to HPV vaccine administration.

RESUMO

Hispanic family caregivers of people with dementia experience higher levels of stress compared to non-Hispanic white caregivers. Long-term stress causes depression, caregiver burden, cellular aging, and dysregulation of the immune, nervous, and endocrine systems. The purpose of this study was to determine the validity of the Spanish version of the English Stress-Busting Program (SBP) for Family Caregivers by determining changes in quality-of-life measures and biomarkers. Thirty-six caregivers completed the SBP in the language of their choice (14 Spanish-speaking Hispanics [HS], 8 English-speaking Hispanics [HE], and 14 non-Hispanic English [NHE] speakers). Quality-of-life measures included the Perceived Stress Scale, the Screen for Caregiver Burden, and the Center for Epidemiologic Studies Depression Scale. Assessment of oral health and immunity included salivary flow rate, pH, buffer capacity, total protein, and secretory immunoglobulin A (sIgA). Indicators of stress (salivary cortisol), inflammation (C-reactive protein), and cellular aging (leukocyte telomere length) were assessed. Following completion of the SBP, the Spanish-speaking group had less depression and caregiver burden along with improved oral health and reduced cellular aging. When comparing baseline values to post-intervention, all three groups showed significant improvement in subjective caregiver burden. When the data from all three groups were combined, biomarkers that showed improvement after nine weeks of SBP included the stress hormone cortisol, salivary pH, and leukocyte telomere length. The results indicate that the Spanish SBP reduces caregiver stress as assessed by quality-of-life indicators and biomarkers. The Spanish SBP can help to mitigate health disparities in Hispanic Spanish-speaking caregivers.

RESUMO

Chronic hepatitis C virus (HCV) increases the risk for hepatocellular carcinoma. Despite higher prevalence of HCV in persons born 1945-1965 (baby boomer), screening has not been widely adopted. Both primary care providers (PCPs) and associate care providers (ACPs) need to be educated about the rationale and methods to screen for HCV. In five Federally Qualified Health Centers serving low-income Hispanic communities, PCPs and ACPs attended a 50-min training lecture about HCV epidemiology, screening methods, and evaluation. Using a 12-item questionnaire, knowledge and attitudes were compared for PCPs and ACPs at baseline (pre-test) and following training (post-test). A higher proportion of PCPs correctly answered 3 of 6 knowledge questions on both pre-test and post-test but ACPs' showed more improvement in knowledge (all P < 0.05). ACPs had more favorable attitudes about linking patients to care on pre- and post-tests than PCPs, and ACPs' attitudes improved on all 6 items versus 4 for PCPs. Both PCPs and ACPs improved knowledge and attitudes after training about HCV screening but ACPs had more favorable attitudes than PCPs. Engaging the entire primary care practice team in learning about HCV screening promotes knowledge and attitudes necessary for successful implementation.

RESUMO

AIMS AND OBJECTIVES: To identify support needs of low-income baby boomers recently diagnosed with chronic hepatitis C virus infection. BACKGROUND: The U.S. Preventive Services Task Force has endorsed one-time screening of all baby boomers (born 1945-1965) for hepatitis C because 75% of the estimated 2-3 million persons with chronic infection are in this age range. We hypothesised that persons diagnosed by routine screening would have significant psycho-emotional, cognitive and healthcare challenges that need to be met by collaborative care and services from nurses and other healthcare personnel. DESIGN: Qualitative descriptive study of data from three focus groups with predominantly minority participants (N = 16). Data were analysed using qualitative content analysis, and transcribed data were categorised by three domains in a previously developed model and a new domain identified in this study. Frequencies of unique participants' comments about each theme were calculated. RESULTS: Elucidated domains were as follows: (i) psycho-emotional effects due to social stigma, shame, fear and dealing with risky behaviours; (ii) social effects due to concerns about infecting others; and (iii) cognitive deficits because of poor understanding about hepatitis C virus infection and its care. A new domain related to health care emerged reflecting the following themes: poor access to care, barriers to costly treatment, and navigating complex care for comorbidities. Despite these challenges, participants strongly endorsed universal baby boomer hepatitis C virus screening. CONCLUSIONS: This study describes psycho-emotional and social challenges of people dealing with a hepatitis C diagnosis which are compounded by poor knowledge and barriers to supportive care. RELEVANCE TO CLINICAL PRACTICE: Nursing and other allied health personnel require structured support programmes to assist older persons diagnosed with hepatitis C with addressing these common challenges with the ultimate goal of achieving a cure.

RESUMO

BACKGROUND: Inulin and other fructans are synthesized and stored in mezcal agave (Agave salmiana). Fructans provide several health benefits and have excellent technological properties, but only few data report their physiological effect when added in the diet. RESULTS: Here, we studied the physiological effects of fructans obtained from A. salmiana when added in the diet of Wistar rats. Results showed favorable changes on Wistar rats when the fructans was added to their diet, including the decrease of the pH in the feces and the increase of the number of lactic acid bacteria (CFU g-1 ) (Lactobacillus spp. and Bifidobacterium spp.), even these changes were enhanced with the synbiotic diet (fructans plus B. animalis subsp. lactis). Synbiotic diet, developed changes in the reduction of cholesterol and triglycerides concentrations in serum, with statistical differences (P < 0.05). Histological analysis of colon sections showed that synbiotic diet promoted colon cells growth suggesting that fructans from A. salmiana confer beneficial health effects through gut microbiota modulation. CONCLUSION: Our data underline the advantage of targeting the gut microbiota by colonic nutrients like specific structure of fructans from A. salmiana, with their beneficial effects. More studies are necessary to define the role of fructans to develop more solid therapeutic solutions in humans. © 2016 Society of Chemical Industry.

RESUMO

SOX2 anophthalmia syndrome is an uncommon autosomal dominant syndrome caused by mutations in the SOX2 gene and clinically characterized by severe eye malformations (anophthalmia/microphthalmia) and extraocular anomalies mainly involving brain, esophagus, and genitalia. In this work, a patient with the SOX2 anophthalmia syndrome and exhibiting a novel dental anomaly is described. SOX2 genotyping in this patient revealed an apparently de novo c.70del20 deletion, a commonly reported SOX2 mutation. A review of the phenotypic variation observed in patients carrying the recurrent SOX2 c.70del20 mutation is presented. Although dental anomalies are uncommonly reported in the SOX2 anophthalmia syndrome, we suggest that a dental examination should be performed in patients with SOX2 mutations.

RESUMO

INTRODUCTION: Vaccine mandates are controversial, and people vary widely in their preferences to support or reject vaccine mandates. For some, vaccine mandates represent a commitment to reduce harm and support public health. For others, vaccine mandates are viewed as a threat to individual freedom and a violation of personal choice. This manuscript investigated support for a COVID-19 vaccine mandate among COVID-19-vaccinated individuals and identified differences by demographic characteristics and COVID-19 experience. METHODS: Cross-sectional surveys were given to COVID-19-vaccinated individuals at a vaccination clinic in South Texas in the U.S. with the goal of identifying attitudes, beliefs, and perceptions about COVID-19 vaccination and willingness to support a COVID-19 vaccination mandate. Associations of interest were analyzed using descriptive statistics. KEY RESULTS: Approximately half of the sample was of Hispanic or Latino origin (48 %); most respondents identified as White (59 %), followed by 12 % who identified as Asian. Overall, 59 % of participants supported the possibility for a COVID-19 vaccine mandate. Preliminary data showed significant racial differences in willingness to support a possible COVID-19 vaccine mandate (χ2 (1, n = 893) = 26.7, p < .001, phi = .17); 80 % of Asian people reported support for COVID-19 vaccination mandate compared to 50 % to 57 % for other racial groups. Significant differences also emerged by ethnicity (χ2 (4, n = 1033) = 7.12, p = .008, phi = .08) whereby a higher percentage of Latino participants (66 %) reported willingness to support a COVID-19 vaccine mandate. Similarly, significant differences were found by age (χ2 (4, n = 1045) = 20.92, p < .001, phi = .21), yet no significant differences were found by sex or previous COVID-19 diagnosis. CONCLUSION: Support for a COVID-19 vaccination mandate is controversial even among vaccinated people. Identifying and understanding cultural and contextual factors that underlie differences in attitudes and beliefs about COVID-19 vaccination mandates is essential to advance dialogue and inform educational health campaigns to increase COVID-19 vaccination rates.

RESUMO

Despite efforts to dissuade major manufacturers and retailers from marketing and selling vape products to adolescents, the practice of vaping continues to increase in this population. Few studies have assessed adolescent perceptions of vaping, access to vaping, and use of vaping, and most rely, at least in part, on inferential conclusions drawn from data on smoking traditional combustible cigarettes. A novel electronic survey was created to assess the use of vapes, perceptions of vaping, and access to vaping among a convenience sample of adolescents (ages 12-20 years) in eleven schools in South-Central Texas from May to August 2021. The students' perceived threat of negative health outcomes due to vaping was calculated based on questions soliciting perceptions of severity (perceived danger) and susceptibility (perceived likelihood of illness). Trends were identified using descriptive and bivariate statistical tests. A total of 267 respondents were included; 26% had tried vaping. A majority (63%) did not believe vaping and smoking were synonymous. Most (70%) thought it was easy to obtain supplies and (76%) vape before and after (88%) or even during (64%) school. Respondents who vaped had a 34% lower perceived threat when compared to respondents who did not vape. In this sample of adolescents from South-Central Texas, one in four reported that they had tried vaping. Easy access to vapes and misperceptions regarding the safety of vaping might create a false sense of security with respect to vaping as an alternative to smoking, particularly among those who reported vaping, and is likely contributing to the increased use of vapes.

RESUMO

The use of antibiotics unbalances the intestinal microbiota. Probiotics, prebiotics, and synbiotics are alternatives for these unbalances. The effects of a new synbiotic composed of probiotic Saccharomyces boulardii CNCM I-745 and fructans from Agave salmiana (fAs) as prebiotics were assessed to modulate the intestinal microbiota. Two probiotic presentations, the commercial probiotic (CP) and the microencapsulated probiotic (MP) to improve those effects, were used to prepare the synbiotics and feed Wistar rats subjected to antibiotics (AB). Eight groups were studied, including five controls and three groups to modulate the microbiota after the use of antibiotics: G5: AB + MP-synbiotic, G6: AB + CP-synbiotic, and G8: AB + fAs. All treatments were administered daily for 7 days. On days 7 and 21, euthanasia was performed, cecum tissue was recovered and used to evaluate histological analysis and to study microphotograph by TEM, and finally, bacterial DNA was extracted and 16S rRNA gene metabarcode sequencing was performed. Histological analysis showed less epithelial damage and more abundance of the intestinal microbiota in the groups G5, G6, and G8 in comparison with the AB control group after 7 days. Microphotograph of the cecum at 2 weeks post treatment showed that G5 and G6 presented beneficial effects in epithelial reconstruction. Interestingly, in the groups that used the synbiotic without AB (G3 and G4) in addition to contributing to the recovery of the autochthonous microbiota, it promotes the development of beneficial microorganisms; those results were also achieved in the groups that used the synbiotic with AB enhancing the bacterial diversity and regulating the impact of AB.

RESUMO

Fructans contribute significantly to dietary fiber with beneficial effects on gastrointestinal physiology in healthy individuals and offer a promising approach to treating some diseases. Two experiments (Experiment 1 = rats with normal weight; Experiment 2 = obese rats) were developed to compare the effects of three fructan sources (Cichorium intybus L. Asteraceae, Helianthus tuberosus L. Asteraceae and Agave angustifolia ssp. tequilana Haw, Agavaceae) on body weight change, blood metabolites and fecal bacteria in non-diabetic (ND) and diabetic (D) rats. In Experiment 1 total body weight gain and daily feed intake in D and ND rats decreased (P < 0.05) with supplements of fructan. Only in D rats, blood glucose concentrations, fecal Clostrodium spp. counts, and liver steatosis decreased, while blood HDL concentrations and fecal Lactobacillus spp. and Bifidobacterium spp. counts increased due to fructans. In Experiment 2, total body weight gain and feed intake in ND and D rats were also decreased by fructans. In ND rats, fructan decreased blood glucose concentrations. In D rats, fructans from A. angustifolia ssp. tequilana decreased blood cholesterol and LDL and liver steatosis. For both ND and D rats, fecal Lactobacillus spp. and Bifidobacterium spp. counts were higher (P < 0.05) with fructan supplements.

RESUMO

Objective: Completion of human papillomavirus (HPV) vaccine series among Texas Hispanic adolescents is low compared to national data. We examined the association between HPV vaccine initiation and completion among Hispanic adolescents in a rural, Texas-Mexico border county and specific individual and neighborhood-level characteristics. Design: Cross-sectional analysis of data from a broader cancer prevention program. Setting: Underserved colonias communities in a Texas-Mexico border county. Participants: Hispanic mothers or caregivers (n=712) and adolescents aged 11-17 years (n=1120) linked to publicly available data about their neighborhood. Main Outcome Measures: HPV vaccine adherence (ie, initiation and completion) as reported in either the Texas Immunization Registry or adolescents' electronic medical records, measured at the end of the cancer prevention program. Methods: Logit and multi-level mixed-effects logistic regression of individual- and neighborhood-level data. Results: Factors associated with HPV vaccine initiation and completion were female gender (P<.01), adolescent insurance status (P<.001), and receipt of required vaccines (P<.001). After controlling for neighborhood-level characteristics, only receipt of required vaccines remained significant. Conclusions: Findings indicate a relationship between Hispanic adolescents' receiving the required vaccine series for school admission and HPV vaccine initiation and completion. In resource-limited settings like federally qualified health centers, further efforts should focus on implementing best practices at both the provider level (eg, education on bundled vaccine recommendation) and practice-level (eg, outreach and support by trained immunization navigators).

RESUMO

In Mexico, few studies have analyzed the associations between toxic elements and metabolic diseases. In the present study, we analyzed the associations between serum arsenic (As), cadmium (Cd), and mercury (Hg) levels and body mass index (BMI) and fasting plasma glucose (FPG) in a Mexican adult population. Anthropometric data corresponding to 86 Mexican healthy adults (59 females and 27 men) were analyzed. FPG was analyzed by an enzymatic colorimetric method, and serum As, Cd, and Hg levels were analyzed by inductively coupled plasma-mass spectrometry (ICP-MS). The data show that the median serum As, Cd, and Hg levels were relatively higher in females (As = 1.78 ng mL-1, Cd = 1.00 ng mL-1, Hg = 0.96 ng mL-1) than those in males (As = 1.22 ng mL-1, Cd = 0.91 ng mL-1, Hg = 0.95 ng mL-1). However, these differences were not statistically significant (p ≥ 0.097). We also found that the median level of As significantly increased with an increase in the body weight categories (normal weight = 1.08; overweight = 1.50; obesity = 2.75; p < 0.001). In addition, a positive association between serum As levels and FPG before and after adjustment for BMI was demonstrated (RhoUnadjusted = 0.012; (RhoAdjusted = 0.243, p = 0.032). Serum As levels are positively associated with BMI and FPG in the adult population of Mexico. Nevertheless, these results need to be replicated and confirmed with a larger sample size.

RESUMO

BACKGROUND: Lead (Pb) exposure has been associated with cardiovascular diseases and metabolic syndrome, nevertheless its association with obesity, type 2 diabetes, and dyslipidemia markers has been little explored in Mexico. Therefore, we evaluated the association of serum Pb levels (Pb-S), with body mass index (BMI), fasting plasma glucose (FPG), total cholesterol (TC), and triglycerides (TG). METHODS: A cross-sectional study was performed on 85 Mexican adults (57 women and 28 men). BMI was calculated, while FPG, TC, and TG were measured by the enzymatic colorimetric method. Total Pb-S levels were measured using inductively coupled plasma mass spectrometry (ICP-MS). RESULTS: The study population was 20.3 ± 1.9 years old, showed an average of Pb-S of 0.0982 ± 0.068 µg dL-1, and presented a frequency of overweight (OW) and obesity (OB) of 50.5% and 18.8%, respectively. Men had higher average FPG than women (Women= 83.930 ± 5.662 vs Men= 84.953 ± 6.495; p = 0.037). When we analyzed anthropometric and clinical variables, Pb-S and frequency of OW and OB were observed to increase within the categories of Pb-S tertiles (<0.001). The averages of Pb-S were 0.051 ± 0.035 µg dL-1, 0.107 ± 0.067 µg dL-1, and 0.151 ± 0.063 µg dL-1 for individuals with normal weight (NW), OW, and OB, respectively. In addition, an analysis adjusted for age and sex shows Pb-S is positively associated with BMI (ß = 2.76 ± 0.498, p = <0.001). CONCLUSION: Our results evidence a significant association between Pb-S and the increase of BMI in Mexican adults and highlight the important health impact that may represent environmental Pb exposure.

RESUMO

BACKGROUND: Cancer is a taxing chronic disease that demands substantial care, most of which is shouldered by informal caregivers. As a result, cancer caregivers often have to manage considerable challenges that could result in severe physical and psychological health consequences. Technology-based interventions have the potential to address many, if not all, of the obstacles caregivers encounter while caring for patients with cancer. However, although the application of technology-based interventions is on the rise, the term is seldom defined in research or practice. Considering that the lack of conceptual clarity of the term could compromise the effectiveness of technology-based interventions for cancer caregivers, timely research is needed to bridge this gap. OBJECTIVE: This study aims to clarify the meaning of technology-based interventions in the context of cancer caregiving and provide a definition that can be used by cancer caregivers, patients, clinicians, and researchers to facilitate evidence-based research and practice. METHODS: The 8-step concept analysis method by Walker and Avant was used to analyze the concept of technology-based interventions in the context of cancer caregiving. PubMed, PsycINFO, CINAHL, and Scopus were searched for studies that examined technology-based interventions for cancer caregivers. RESULTS: The defining attributes of technology-based interventions were recognized as being accessible, affordable, convenient, and user-friendly. On the basis of insights gained on the defining attributes, antecedents to, and consequences of technology-based interventions through the concept analysis process, technology-based interventions were defined as the use of technology to design, develop, and deliver health promotion contents and strategies aimed at inducing or improving positive physical or psychological health outcomes in cancer caregivers. CONCLUSIONS: This study clarified the meaning of technology-based interventions in the context of cancer caregiving and provided a clear definition that can be used by caregivers, patients, clinicians, and researchers to facilitate evidence-based oncology practice. A clear conceptualization of technology-based interventions lays foundations for better intervention design and research outcomes, which in turn have the potential to help health care professionals address the needs and preferences of cancer caregivers more cost-effectively.

RESUMO

PURPOSE: Type 2 diabetes mellitus (T2DM) is an urgent public health problem and disproportionately affects Mexican Americans. The gut microbiome contributes to the pathophysiology of diabetes; however, no studies have examined this association in Mexican-Americans. The objective of this study was to compare gut microbiome composition between Mexican-Americans with and without T2DM. METHODS: This was a cross-sectional study of volunteers from San Antonio, TX. Subjects were 18 years or older and self-identified as Mexican American. Subjects were grouped by prior T2DM diagnosis. Eligible subjects attended a clinic visit to provide demographic and medical information. Thereafter, subjects recorded their dietary intake for three days and collected a stool sample on the fourth day. Stool 16s rRNA sequences were classified into operational taxonomic units (OTUs) via the mothur bayesian classifier and referenced to the Greengenes database. Shannon diversity and bacterial taxa relative abundance were compared between groups using the Wilcoxon rank sum test. Beta diversity was estimated using Bray-Curtis indices and compared between groups using PERMANOVA. RESULTS: Thirty-seven subjects were included, 14 (38%) with diabetes and 23 (62%) without diabetes. Groups were well-matched by body mass index and comorbid conditions. Shannon diversity was not significantly different between those with and without T2DM (3.26 vs. 3.31; p = 0.341). Beta diversity was not significantly associated with T2DM diagnosis (p = 0.201). The relative abundance of the most common bacterial phyla and families did not significantly differ between groups; however, 16 OTUs were significantly different between groups. CONCLUSIONS: Although alpha diversity was not significantly different between diabetic and non-diabetic Mexican Americans, the abundance of certain bacterial taxa were significantly different between groups.

RESUMO

Background: Cancer patients are particularly vulnerable to COVID-19, partially owing to their compromised immune systems and curbed or cut cancer healthcare services caused by the pandemic. As a result, cancer caregivers may have to shoulder triple crises: the COVID-19 pandemic, pronounced healthcare needs from the patient, and elevated need for care from within. While technology-based health interventions have the potential to address unique challenges cancer caregivers face amid COVID-19, limited insights are available. Thus, to bridge this gap, we aim to identify technology-based interventions designed for cancer caregivers and report the characteristics and effects of these interventions concerning cancer caregivers' distinctive challenges amid COVID-19. Methods: A systematic search of the literature will be conducted in PubMed, PsycINFO, CINAHL, and Scopus from the database inception to the end of March, 2021. Articles that center on technology-based interventions for cancer caregivers will be included in the review. The search strategy will be developed in consultation with an academic librarian who is experienced in systematic review studies. Titles, abstracts, and full-text articles will be screened against eligibility criteria developed a priori. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses procedures will be followed for the reporting process. Conclusions: COVID-19 has upended cancer care as we know it. Findings of this study can shed light on evidence-based and practical solutions cancer caregivers can utilize to mitigate the unique challenges they face amid COVID-19. Furthermore, results of this study will also offer valuable insights for researchers who aim to develop interventions for cancer caregivers in the context of COVID-19. In addition, we also expect to be able to identify areas for improvement that need to be addressed in order for health experts to more adequately help cancer caregivers weather the storm of global health crises like COVID-19 and beyond.

RESUMO

Demand for building competencies in implementation research (IR) outstrips supply of training programs, calling for a paradigm shift. We used a bootstrap approach to leverage external resources and create IR capacity through a novel 2-day training for faculty scientists across the four Texas Clinical & Translational Science Awards (CTSAs). The Workshop combined internal and external expertise, targeted nationally established IR competencies, incorporated new National Institutes of Health/National Cancer Institute OpenAccess online resources, employed well-known adult education principles, and measured impact. CTSA leader buy-in was reflected in financial support. Evaluation showed increased self-reported IR competency; statewide initiatives expanded. The project demonstrated that, even with limited onsite expertise, it was possible to bootstrap resources and build IR capacity de novo in the CTSA community.
