RESUMEN

BACKGROUND: The objective of this randomized trial was to evaluate the short-term effect of bilingual written and interpersonal education regarding mammographic breast density (MBD). METHODS: Latinas aged 40 to 74 years who were presenting for screening mammography were recruited and randomized 1:1:1 to receive a letter with their mammogram and MBD results (usual care [UC]), a letter plus a brochure (enhanced care [ENH]), or a letter plus a brochure and telephonic promotora education (interpersonal care [INT]). Surveys were administered at enrollment (T0 ) and 2 weeks to 6 months after intervention delivery (T1 ). Differences were assessed with χ2 , Kruskal-Wallis, and McNemar tests and pairwise comparisons as appropriate. INT metrics and audio recordings were analyzed with descriptive statistics and qualitative content analysis. RESULTS: Between October 2016 and October 2019, 943 of 1108 Latina participants (85%) completed both surveys. At T1 , INT participants were more likely (P < .001) to report seeing their MBD results in the letter (70.2%) than UC (53.1%) or ENH participants (55.1%). The percentage of INT women who reported speaking with a provider about MBD (29.0%) was significantly greater (P < .001) than the percentage of UC (14.7%) or ENH participants (15.6%). All groups saw significant (P < .001) but nondifferential improvements in their knowledge of MBD as a masking and risk factor. In the INT group, the promotora delivered education to 77.1% of the 446 participants randomized to INT and answered questions at 28.3% of the encounters for an average of $4.70 per participant. CONCLUSIONS: Among Latinas in a low-resource setting, MBD knowledge may increase with written or interpersonal education, but with modest investment, interpersonal education may better improve MBD awareness and prompt patient-provider discussions.

RESUMEN

PURPOSE: Multiple efforts are underway to increase the inclusion of racial minority participants in genomic research and new forms of individualized medicine. These efforts should include studies that characterize how individuals from minority communities experience genomic medicine in diverse health-care settings and how they integrate genetic knowledge into their understandings of health-care needs. METHODS: As part of a large, multisite genomic sequencing study, we surveyed individuals to assess their decision to pursue genomic risk evaluation. Participants included Latino patients recruited at Mountain Park Health Center, a Federally Qualified Health Center in Phoenix, Arizona, and non-Latino patients recruited at a large academic medical center (Mayo Clinic in Rochester, MN). Both groups agreed to receive individualized genomic risk assessments. RESULTS: Comparisons between cohorts showed that Latino respondents had lower levels of decisional conflict about pursuing genomic screening but generally scored lower on genetic knowledge. Latino respondents were also more likely to have concerns about the misuse of genomic information, despite both groups having similar views about the value of genomic risk evaluation. CONCLUSION: Our results highlight the importance of evaluating sociocultural factors that influence minority patient engagement with genomic medicine in diverse health-care settings.

RESUMEN

PURPOSE: This report describes the return of sequencing results to low-income Latino participants recruited through a Federally Qualified Health Center (FQHC). We describe challenges in returning research results secondary to social determinants of health and present lessons learned to guide future genomic medicine implementation studies in low-resource settings. METHODS: Five hundred Latino adults (76% women) consented to research sequencing for a predetermined panel of actionable genes. Providers and staff from the FQHC were engaged to align processes with the practice and a community advisory board grounded the project in the local community. RESULTS: A pathogenic/likely pathogenic variant was present in 10 participants (2%). Challenges in return of results included the time lag (582 ± 53 days) between enrollment and returning actionable results, difficulty reaching participants, missed appointments, low health literacy, lack of health insurance, and reconciling results with limited information on family history. Return of one actionable result was deferred due to acute emotional distress secondary to recent traumatic life events. CONCLUSION: The social determinants of health influence the implementation of genomic medicine in low-income populations in low-resource settings. Considering nonbiological factors that contribute to disparities will be necessary to better appreciate how genomic medicine may fit within the context of health equity.

RESUMEN

The microbiota associated with phytophagous insects perform several functions that help insects exploit plant resources. Thus, microorganisms contribute to the dispersal of phytophagous species to new host plants, thereby promoting diversification. In this study, metatranscriptomic analysis was used to compare the gene expression of the microbiome of Anastrepha obliqua Macquart larvae feeding on 3 of its host plants: Spondias purpurea L (red mombin), Mangifera indica L (mango), and Averrhoa carambola L (starfruit). To identify differential gene expression in relation to the host plant, transcript abundance was compared. The results of the taxonomic and functional beta-diversity analysis showed that there were significant differences in the structures and activities of the microbial communities depending on the infested plant. Among the microorganisms, bacteria and fungi were active components of the microbiota. Differential expression analyses showed that the different active genes in each of the plants analyzed were mainly grouped into categories related to carbohydrate and amino acid metabolism, with some of these genes coding for cytochrome o ubiquinol oxidase, cytochrome c, and the enzyme isocitrate dehydrogenase. The microbiota of A. carambola larvae differed more at the level of community structure and gene function, possibly due to the different nutritional composition of the A. carambola and the presence of a set of secondary metabolites specific to the family Oxalidaceae. In conclusion, the transcriptional activity of the microbiota of A. obliqua larvae is influenced by diet, which is important because it could influence the performance of the insect on each of its different host plants.

RESUMEN

BACKGROUND: Understanding factors that shape breast cancer risk perceptions is essential for implementing risk-based approaches to breast cancer detection and prevention. This study aimed to assess multilevel factors, including prior screening behavior, shaping underserved, Hispanic women's perceived risk for breast cancer. METHODS: Secondary analysis of survey data from Hispanic women (N = 1325, 92% Spanish speaking, 64% < 50) enrolled in a large randomized controlled trial. Analyses were performed in two cohorts to account for the role of age on screening guideline recommendations (< 50 and 50 +). For each cohort, we examined differences in three common measures of perceived risk of breast cancer (percent lifetime, ordinal lifetime, comparative) by participant factors with chi-square or Kruskal-Wallis tests, as appropriate. Multivariate analyses examined the association between mammography history with percent perceived lifetime risk (outcome > 10 vs ≤ 10%). RESULTS: Overall, 75% reported a lifetime risk between 0 and 10%, 96% rated their ordinal risk as "not high," and 50% rated their comparative risk as "much lower." Women < 50 with a family history of breast cancer reported significantly higher levels of perceived risk across all three measures. Among women 50 + , those reporting lower levels of perceived risk were significantly more likely to be Spanish speaking. No significant association was observed between mammography history and percent lifetime risk of breast cancer. CONCLUSION: Factors shaping breast cancer risk perceptions differ by age. Prior screening may play less of role in constructing risk perceptions. Research is needed to develop culturally and linguistically appropriate strategies to improve implementation of risk-based screening.

RESUMEN

Importance: Hispanic adults with type 2 diabetes (T2D) are more likely to develop complications and die from the disease than the US general population. Digital storytelling interventions are narrative-based videos elicited through a community-based participatory research approach to surface the authentic voices of participants overcoming obstacles to health-promoting behaviors that perpetuate health inequities; research on the effect of digital storytelling on T2D outcomes among Hispanic adults is lacking. Objective: To assess the impact of a digital storytelling intervention on glycemic control and its acceptability among Hispanic patients with poorly controlled T2D. Design, Setting, and Participants: This was a multicenter, randomized clinical trial conducted within 2 primary care networks in Minnesota and Arizona among Hispanic adults with poorly controlled T2D (hemoglobin A1c level ≥8%). Enrollment and follow-up were conducted between February 14, 2019, and November 1, 2023. Intervention: The intervention group viewed a 12-minute digital storytelling video. The video included 4 Spanish-language stories that reinforced 4 diabetes self-management behavioral goals (healthful diet for diabetes, physical activity, medication adherence, and glucose self-monitoring). The control group received printed, culturally tailored T2D education materials. Main Outcomes and Measures: The primary outcome was the mean change from baseline to 3 months for hemoglobin A1c levels, adjusting for baseline hemoglobin A1c, age, gender, education, and income. Acceptability and narrative quality of the intervention were assessed through questionnaires. Results: There were 451 study participants, with 227 (mean [SD] age, 54.3 [9.3] years; 158 [69.3%] women) randomized to the intervention group and 224 (mean [SD] age, 54.5 [9.1] years; 156 [69.3%] women) to the control group. Of these, 390 completed 3-month follow-up of the primary outcome (86% retention). There was a small improvement in the mean (SD) hemoglobin A1c level in the intervention group compared with the control group in the adjusted model (9.1% [1.7] to 8.4% [1.6] vs 9.4% [1.8] to 8.8% [2.0]; P = .04] but not in the unadjusted model. Acceptability and narrative quality of the intervention were high. Conclusions and Relevance: In this randomized clinical trial, a digital storytelling intervention developed with and for Hispanic adults with T2D was highly acceptable and feasibly implemented within primary care settings and resulted in a modest improvement of glycemic control. This was a highly scalable intervention that may be integrated into clinical practice as part of a longitudinal diabetes self-management program for Hispanic adults. Trial Registration: ClinicalTrials.gov Identifier: NCT03766438.

RESUMEN

Unlike filamentous fungi and bacteria, very little is known about cultivable yeasts associated with marine sponges, especially those from Antarctic seas. During an expedition to King George Island, in the Antarctica, samples of 11 marine sponges were collected by scuba-diving. From these sponges, 20 psychrotolerant yeast isolates were obtained. Phylogenetic analyses of D1/D2 and ITS rRNA gene sequences revealed that the marine ascomycetous yeast Metschnikowia australis is the predominant organism associated with these invertebrates. Other species found belonged to the Basidiomycota phylum: Cystofilobasidium infirmominiatum, Rhodotorula pinicola, Leucosporidiella creatinivora and a new yeast from the Leucosporidiella genus. None of these yeasts have been previously associated with marine sponges. A screening to estimate the ability of these yeasts as producers of extracellular enzymatic activities at several pH and temperature conditions was performed. Several yeast isolates demonstrated amylolytic, proteolytic, lipolytic or cellulolytic activity, but none of them showed xylanolytic activity under the conditions assayed. To our knowledge, this work is the first description of cultivable yeasts associated with marine sponges from the Antarctic sea.

RESUMEN

Restless sleep disorder (RSD) is a condition recently described by a group of sleep experts who developed diagnostic and polysomnographic criteria after conducting a comprehensive review of the available literature where poor sleep or restless sleep is a symptom alone or that accompanies other disorders. This group defined RSD as a condition characterized by parental complaints of frequent jerking movements during sleep, position changes, and sleep disruption that cause significant impairment during the day. Diagnostic criteria include the presence of symptoms for at least 3 months, 3 times a week, and at least 5 movements per hour on polysomnography. Changes in behavior during the day, such as drowsiness, irritability, and hyperactivity that are not explained by a medical, pharmacological, or behavioral condition, should be considered. Its estimated prevalence is 7.7% of children referred for sleep problems. Children often have ferritin levels below 50 µg/l, a point in common with restless legs syndrome. Treatment consists of iron supplements, which have shown benefits in these children. To establish the diagnosis, secondary symptoms of medical origin or other sleep disorders such as restless legs syndrome or periodic limb movement disorder must be ruled out. The objective of this report is to review the current recommendations on this entity, describe the clinical, pathophysiological, and polysomnographic keys, in order to highlight the need to publicize this condition and expand studies in age groups other than those already defined and to generate treatment guidelines.

RESUMEN

BACKGROUND: Hispanic/Latino adults are disproportionately impacted by type 2 diabetes mellitus (T2D). The Stories for Change (S4C) Diabetes digital storytelling intervention promotes T2D self-management among Hispanic/Latino people. We describe the S4C protocol and participant baseline characteristics. METHODS: Study eligibility criteria: Hispanic or Latino, age 18-70 years, ≥1 office visit within a year at a participating clinic, T2D diagnosis for ≥6 months, HbA1c ≥ 8%, and intention to continue care at the recruitment clinic. We used a two-group, parallel randomized controlled trial design and an intervention derived through a community-based participatory research approach. All participants received usual diabetes care and two cards describing how to engage healthcare teams and access diabetes-related resources. At baseline, the intervention group additionally viewed the 12-min, intervention video (four stories about diabetes self-management). To encourage subsequent video viewing, participants received five monthly text messages. The messages prompted them to self-rate their motivation and self-efficacy for T2D management. The control group received no additional intervention. Bilingual (English/Spanish) staff collected data at baseline, six weeks, three months, and six months including biometric measurements and a survey on diabetes self-management outcomes, theory-based measures, and the number of video views. We reviewed the number of diabetes-related appointments attended using electronic medical record data. RESULTS: Participants (n = 451; 70% women, mean age = 53 years) had an average HbA1C ≥9%. Intervention participants reported identifying with the storytellers and engaging with the stories. CONCLUSION: We present a digital storytelling intervention protocol that provides a template for future health promotion interventions prioritizing health disparity populations.

RESUMEN

CONTEXT: Metformin is the first-line drug for treating diabetes but has a high failure rate. OBJECTIVE: To identify demographic and clinical factors available in the electronic health record (EHR) that predict metformin failure. METHODS: A cohort of patients with at least 1 abnormal diabetes screening test that initiated metformin was identified at 3 sites (Arizona, Mississippi, and Minnesota). We identified 22 047 metformin initiators (48% female, mean age of 57 ± 14 years) including 2141 African Americans, 440 Asians, 962 Other/Multiracial, 1539 Hispanics, and 16 764 non-Hispanic White people. We defined metformin failure as either the lack of a target glycated hemoglobin (HbA1c) (<7%) within 18 months of index or the start of dual therapy. We used tree-based extreme gradient boosting (XGBoost) models to assess overall risk prediction performance and relative contribution of individual factors when using EHR data for risk of metformin failure. RESULTS: In this large diverse population, we observed a high rate of metformin failure (43%). The XGBoost model that included baseline HbA1c, age, sex, and race/ethnicity corresponded to high discrimination performance (C-index of 0.731; 95% CI 0.722, 0.740) for risk of metformin failure. Baseline HbA1c corresponded to the largest feature performance with higher levels associated with metformin failure. The addition of other clinical factors improved model performance (0.745; 95% CI 0.737, 0.754, P < .0001). CONCLUSION: Baseline HbA1c was the strongest predictor of metformin failure and additional factors substantially improved performance suggesting that routinely available clinical data could be used to identify patients at high risk of metformin failure who might benefit from closer monitoring and earlier treatment intensification.

RESUMEN

PURPOSE: The purpose of this study was to characterize the material, health (general and diabetes-specific), and social impacts of the COVID-19 pandemic on Hispanic adults with type 2 diabetes who did not experience COVID-19 infection. METHODS: This cross-sectional and longitudinal study used surveys within a clinical trial of 79 Hispanic adult clinic patients with type 2 diabetes. Cross-sectional measures included the Coronavirus Anxiety Scale, items from the Coronavirus Impact Scale, and the Pandemic Impacts Inventory. Longitudinal measures included the Summary of Diabetes Self-Care, health care utilization, and measures of diabetes self-efficacy, social support, and quality of life. RESULTS: Participants were majority low-income, Spanish-speaking females with poor diabetes control. Coronavirus anxiety was low despite majority of participants having an affected family member and frequent access barriers. More than half of participants reported moderate/severe pandemic impact on their income. Diabetes self-care behaviors did not change between prepandemic and pandemic measures. Diabetes self-efficacy and quality of life improved despite fewer diabetes-related health care visits. CONCLUSIONS: Despite high levels of access barriers, financial strain, and COVID-19 infection of family members, Hispanic adults with type 2 diabetes continued to prioritize their diabetes self-management and demonstrated substantial resilience by improving their self-efficacy and quality of life.

RESUMEN

This article focuses on agar biopolymer films that offer promise for developing biodegradable packaging, an important solution for reducing plastics pollution. At present there is a lack of data on the mechanical performance of agar biopolymer films using a simple plasticizer. This study takes a Design of Experiments approach to analyze how agar-glycerin biopolymer films perform across a range of ingredients concentrations in terms of their strength, elasticity, and ductility. Our results demonstrate that by systematically varying the quantity of agar and glycerin, tensile properties can be achieved that are comparable to agar-based materials with more complex formulations. Not only does our study significantly broaden the amount of data available on the range of mechanical performance that can be achieved with simple agar biopolymer films, but the data can also be used to guide further optimization efforts that start with a basic formulation that performs well on certain property dimensions. We also find that select formulations have similar tensile properties to thermoplastic starch (TPS), acrylonitrile butadiene styrene (ABS), and polypropylene (PP), indicating potential suitability for select packaging applications. We use our experimental dataset to train a neural network regression model that predicts the Young's modulus, ultimate tensile strength, and elongation at break of agar biopolymer films given their composition. Our findings support the development of further data-driven design and fabrication workflows.

RESUMEN

INTRODUCTION: Minority communities have had limited access to advances in genomic medicine. Mayo Clinic and Mountain Park Health Center, a Federally Qualified Health Center in Phoenix, Arizona, partnered to assess the feasibility of offering genomic screening to Latino patients receiving care at a community-based health center. We examined primary care provider (PCP) experiences reporting genomic screening results and integrating those results into patient care. METHODS: We conducted open-ended, semi-structured interviews with PCPs and other members of the health care team charged with supporting patients who received positive genomic screening results. Interviews were recorded, transcribed, and analyzed thematically. RESULTS: Of the 500 patients who pursued genomic screening, 10 received results indicating a genetic variant that warranted clinical management. PCPs felt genomic screening was valuable to patients and their families, and that genomic research should strive to include underrepresented minorities. Providers identified multiple challenges integrating genomic sequencing into patient care, including difficulties maintaining patient contact over time; arranging follow-up medical care; and managing results in an environment with limited genetics expertise. Providers also reflected on the ethics of offering genomic sequencing to patients who may not be able to pursue diagnostic testing or follow-up care due to financial constraints. CONCLUSIONS: Our results highlight the potential benefits and challenges of bringing advances in precision medicine to community-based health centers serving under-resourced populations. By proactively considering patient support needs, and identifying financial assistance programs and patient-referral mechanisms to support patients who may need specialized medical care, PCPs and other health care providers can help to ensure that precision medicine lives up to its full potential as a tool for improving patient care.

RESUMEN

The ectodysplasin receptor (EDAR) is a tumor necrosis factor receptor (TNF) superfamily member. A substitution in an exon of EDAR at position 370 (EDARV370A) creates a gain of function mutant present at high frequencies in Asian and Indigenous American populations but absent in others. Its frequency is intermediate in populations of Mexican ancestry. EDAR regulates the development of ectodermal tissues, including mammary ducts. Obesity and type 2 diabetes mellitus are prevalent in people with Indigenous and Latino ancestry. Latino patients also have altered prevalence and presentation of breast cancer. It is unknown whether EDARV370A might connect these phenomena. The goals of this study were to determine 1) whether EDARV370A is associated with metabolic phenotypes and 2) if there is altered breast anatomy in women carrying EDARV370A. Participants were from two Latino cohorts, the Arizona Insulin Resistance (AIR) registry and Sangre por Salud (SPS) biobank. The frequency of EDARV370A was 47% in the Latino cohorts. In the AIR registry, carriers of EDARV370A (GG homozygous) had significantly (p < 0.05) higher plasma triglycerides, VLDL, ALT, 2-hour post-challenge glucose, and a higher prevalence of prediabetes/diabetes. In a subset of the AIR registry, serum levels of ectodysplasin A2 (EDA-A2) also were associated with HbA1c and prediabetes (p < 0.05). For the SPS biobank, participants that were carriers of EDARV370A had lower breast density and higher HbA1c (both p < 0.05). The significant associations with measures of glycemia remained when the cohorts were combined. We conclude that EDARV370A is associated with characteristics of the metabolic syndrome and breast density in Latinos.

RESUMEN

PURPOSE: The aim of the study was to characterize experiences of Latino participants receiving genomic screening results. METHODS: Participants were recruited at a federally qualified health center in the USA. In-person, semi-structured interviews were conducted in either Spanish or English by a bilingual, bicultural interviewer. Questions focused on motivations for pursuing genomic sequencing, concerns about receiving genomic screening results, and perceived benefits of receiving genomic information. Interviews were audio-recorded, transcribed, and translated. RESULTS: Fifty individuals completed an interview; 39 were conducted in Spanish. Participants described mixed motivations for pursuing genomic screening. Participants viewed the benefits of genomic screening in relation to not only their personal health but to the health of their families and their communities. Participants tended to have few concerns about genomic screening. Those concerns related to potential loss of privacy, misuses of genomic information, and the possibility of receiving distressing results. Some participants had misunderstandings about the scope of the test and the potential implications of their results. Most felt it was better to know about a genetic predisposition to disease than to remain uninformed. Participants felt that genomic screening was worthwhile. DISCUSSION: This is one of the first studies to examine the experiences of Latino individuals receiving genomic screening results. Our results suggest that many Latino patients in the US see value in genomic screening and have limited concerns about its potential to cause harm. These results inform ongoing efforts to increase the availability of genomic medicine to underrepresented populations and add to our understanding of sociocultural drivers in the adoption of precision medicine.

RESUMEN

INTRODUCTION: Latino communities are disproportionately affected by type 2 diabetes and experience disparities in access to diabetes prevention programs. The purpose of this study was to test the preliminary efficacy of a culturally grounded, diabetes prevention program for high-risk Latino families delivered through an integrated research-practice partnership. STUDY DESIGN: The integrated research-practice partnership was established in a predominantly Latino community and consisted of a Federally Qualified Health Center, a YMCA, an accredited diabetes education program, and an academic research center. Data were collected and analyzed from 2015 to 2018. SETTING/PARTICIPANTS: Latino families consisting of a parent with an obese child between age 8 and 12 years. INTERVENTION: The 12-week lifestyle intervention included nutrition education and behavioral skills training (60 minutes, once/week) and physical activity classes (60 minutes, three times/week) delivered at a YMCA. MAIN OUTCOME MEASURES: Outcomes included measures of adiposity (BMI, waist circumference, and body fat); HbA1c; and weight-specific quality of life. RESULTS: Over the course of the 2-year project period, 58 families (parents n=59, children n=68) were enrolled with 36% of parents and 29% of children meeting the criteria for prediabetes at baseline. Feasibility and acceptability were high, with 83% of enrolled families completing the program, 91% of the intervention sessions attended, and 100% of families stating they would recommend the program. The intervention led to significant decreases in percentage body fat among parents (46.4% [SD=10.8] to 43.5% [SD=10.5], p=0.001) as well as children (43.1% [SD=8.0] to 41.8% [SD=7.2], p=0.03). Additionally, HbA1c was significantly reduced in parents (5.6% [SD=0.4] to 5.5% [SD=0.3], p=0.03), and remained stable in children (5.5% [SD=0.3] vs 5.5% [SD=0.3], p>0.05). Significant improvements in quality of life were reported in parents (64.6 [SD=15.8] to 71.0 [SD=13.7], p=0.001) and children (69.7 [SD=15.8] to 72.6 [SD=13.7], p=0.05). CONCLUSIONS: These findings support the preliminary efficacy of an integrated research-practice partnership to meet the diabetes prevention needs of high-risk Latino families within a vulnerable community.

RESUMEN

AIM: To develop a process for returning medically actionable genomic variants to Latino patients receiving care in a Federally Qualified Health Center. METHODS: Prior to recruitment, researchers met with primary care providers to (1) orient clinicians to the project, (2) establish a process for returning actionable and nonactionable results to participants and providers through the electronic health record, and (3) develop a process for offering clinical decision support for follow-up education and care. A Community Advisory Board was engaged to provide input on recruitment strategies and materials for conveying results to participants. Participants in the Sangre Por Salud (Blood for Health) Biobank with hyperlipidemia or colon polyps represented the pool of potentially eligible participants. RESULTS: A total of 1,621 individuals were invited to participate and 710 agreed to an in- person consenting visit (194 no-showed and 16 declined). Over 12-months, 500 participants were enrolled. Participants were primarily Spanish-speaking (81.6%), female (74.2%), and enrolled because of hyperlipidemia (95.4%). All but 2 participants opted to receive primary (i.e., related to enrollment phenotypes) as well as secondary actionable results. CONCLUSION: Efforts to bring precision medicine to community-based health centers serving minority patients may require multilevel engagement activities to include individuals, providers, health systems, and the community.

RESUMEN

Purpose The purpose of this pilot feasibility project was to examine the potential effectiveness of a digital storytelling intervention designed through a community-based participatory research (CBPR) approach for immigrants and refugees with type 2 diabetes mellitus (T2DM). Methods The intervention was a 12-minute culturally and linguistically tailored video consisting of an introduction, 4 stories, and a concluding educational message. A structured interview was used to assess the intervention for acceptability, interest level, and usefulness among 25 participants with T2DM (15 Latino, 10 Somali) across 5 primary care clinical sites. After watching the video, participants rated their confidence and motivation about managing T2DM as a result of the intervention. Baseline A1C and follow-up values (up to 6 months) were abstracted from medical records. Results All participants reported that the intervention got their attention, was interesting, and was useful; 96% reported that they were more confident about managing their T2DM than before they watched the video, and 92% reported that the video motivated them to change a specific behavior related to T2DM self-management. The mean baseline A1C level for the intervention participants was 9.3% (78 mmol/mol). The change from baseline to first follow-up A1C level was -0.8% (-10 mmol/mol) ( P < .05). Conclusions Implementation of a digital storytelling intervention for T2DM among immigrant populations in primary care settings is feasible and resulted in self-rated improvement in psychosocial constructs that are associated with healthy T2DM self-management behaviors, and there was some evidence of improvement in glycemic control. A large-scale efficacy trial of the intervention is warranted.

RESUMEN

BACKGROUND/AIMS: The Sangre Por Salud (Blood for Health; SPS) Biobank was created for the purpose of expanding precision medicine research to include underrepresented Latino patients. It is the result of a unique collaboration between Mayo Clinic and Mountain Park Health Center, a federally qualified community health center in Phoenix, Arizona. This report describes the rationale, development, implementation, and characteristics of the SPS Biobank. METHODS: Latino adults (ages 18-85 years) who were active patients within Mountain Park Health Center's internal medicine practice in Phoenix, Ariz., and had no history of diabetes were eligible. Participants provided a personal and family history of chronic disease, completed a sociodemographic, psychosocial, and behavioral questionnaire, underwent a comprehensive cardiometabolic risk assessment (anthropometrics, blood pressure and labs), and provided blood samples for banking. Laboratory results of cardiometabolic testing were returned to the participants and their providers through the electronic health record. RESULTS: During the first 2 years of recruitment into the SPS Biobank, 2,335 patients were approached and 1,432 (61.3%) consented to participate; 1,354 (94.5%) ultimately completed all requisite questionnaires and medical evaluations. The cohort is primarily Spanish-speaking (72.9%), female (73.3%), with a mean age of 41.3 ± 12.5 years. Most participants were born outside of the US (77.9%) and do not have health insurance (77.5%). The prevalence of overweight (35.5%) and obesity (45.0%) was high, as was previously unidentified prediabetes (55.9%), type 2 diabetes (7.4%), prehypertension (46.8%), and hypertension (16.2%). The majority of participants rated their health as good to excellent (72.1%) and, as a whole, described their overall quality of life as high (7.9/10). CONCLUSION: Collaborative efforts such as the SPS Biobank are critical for ensuring that underrepresented minority populations are included in precision medicine initiatives and biomedical research that seeks to improve human health and reduce the burdens of disease.

RESUMEN

This work presents a techno-economic and environmental assessment of the glucose syrups production from sugarcane bagasse, plantain husk, cassava husk, mango peel, rice husk and corncobs. According to the economic analysis, the corncob had both, the lowest production cost (2.48USD/kg syrup) and the highest yield (0.61kgofsugars/kg of wet agroindustrial waste) due to its high content in cellulose and hemicellulose. This analysis also revealed that a heat integration strategy is necessary since the utilities consumption represent an important factor in the production cost. According to the results, the pretreatment section requires more energy in the syrup production in comparison with the requirements of other sections such as production and sugar concentration. The environmental assessment revealed that the solid wastes such as furfural and hydroxymethylfurfural affected the environmental development of the process for all the agroindustrial wastes, being the rice husk the residue with the lowest environmental impact.
