An Innovative Approach to Promote Weight Loss Among Mexican Immigrants: A Pilot Study.

Mexican Americans are among the highest risk groups for obesity and its associated health consequences, including diabetes, heart disease, and cancer. 154 overweight/obese Mexican Americans recruited from the Mexican Consulate in New York City were enrolled in COMIDA (Consumo de Opciones Más Ideales De Alimentos) (Eating More Ideal Food Options), a 12-week Spanish-language lifestyle intervention that included a dietary counseling session, weight-loss resources, and thrice-weekly text messages. Participants' weight (primary outcome); dietary intake, physical activity, and nutrition knowledge (secondary outcomes) were assessed pre- and post-intervention. Of the 109 who completed follow-up, 28% lost ≥ 5% of their baseline body weight. Post-intervention, participants consumed more fruit and less soda, sweet pastries, fried foods and red meat; increased physical activity; and evidenced greater nutrition knowledge. A community-based lifestyle intervention with automated components such as text messaging may be a scalable, cost-effective approach to address overweight/obesity among underserved populations.

Development and application of proficiency testing (PT) to evaluate the diagnostic capacity of SARS-CoV-2 by RT-qPCR - A practical and metrological approach.

It is necessary to use quality tools to evaluate the diagnostic capacity of laboratories, such as implementing a proficiency testing (PT) program. The goal of this work is to develop and apply a PT protocol to assess the diagnostic capacity of SARS-CoV-2 through the RT-PCR method, based on appropriate metrological tools. A 5-item test panel containing items with different dilutions of SARS-CoV-2, including negative controls, was developed to perform this PT with the application of different performance assessment tools to score and differentiate performance between laboratories, according to Table 2. Based on the participants' total qualitative result, 95% of the negative samples and 73% of the positive samples were correctly identified by the laboratories. The results obtained were compared e validate the systematics of the PT developed, so that it can be implemented and used to monitor and improve the diagnostic capacity of SARS-CoV-2, also helping to improve the quality of these results.

Association of Primary Language with Very Low Birth Weight Outcomes in Hispanic Infants in California.

OBJECTIVE: To determine the association of Spanish as a primary language for a family with the health outcomes of Hispanic infants with very low birth weight (VLBW, <1500g). STUDY DESIGN: Data from the California Perinatal Quality Care Collaborative (CPQCC) linked to hospital discharge records were analyzed. Hispanic infants with VLBW born between 2009 and 2018 with a primary language of English or Spanish were included. Outcomes selected were hypothesized to be sensitive to language barriers. Multivariable logistic regression models and mixed models estimated associations between language and outcomes. RESULTS: Of 18 364 infants meeting inclusion criteria, 27% (n = 4976) were born to families with Spanish as a primary language. In unadjusted analyses, compared with infants of primarily English-speaking families, these infants had higher odds of hospital readmission within 1 year (OR 1.11 [95% CI 1.02-1.21]), higher odds to receive human milk at discharge (OR 1.32 [95% CI 1.23-1.42]), and lower odds of discharge home with oxygen (OR 0.83 [95% CI 0.73-0.94]). In multivariable analyses, odds of readmission and home oxygen remained significant when adjusting for infant but not maternal and hospital characteristics. Higher odds for receipt of any human milk at discharge were significant in all models. Remaining outcomes did not differ between groups. CONCLUSIONS: Significant differences exist between Hispanic infants with VLBW of primarily Spanish-vs English-speaking families. Exploration of strategies to prevent readmissions of infants of families with Spanish as a primary language is warranted.

Conclusions: The experts considered the system adequate in terms of its structure and feasibility of implementation, contributing effectively to the consolidation of cultural training and at the motivational level.

Parental perceptions of bilingualism and home language vocabulary: Young bilingual children from low-income immigrant Mexican American and Chinese American families.

Dual language learners (DLLs), especially those from immigrant families in the United States, risk losing their home language as they gradually shift to speaking English as they grow up. Given the potential benefits of bilingualism on children's cognitive, linguistic, and social-emotional development, it is crucial to maintain children's home language to foster bilingual development. The current literature suggests that parental beliefs toward bilingualism and the language and literacy environment are linked to children's language development. With the growing number of DLLs living in the United States, little is known about what parental beliefs about bilingualism of their children are integrated into these bilingual households and parents' role in home language maintenance. The present study addresses the gap in the literature by investigating low-income immigrant families, specifically Chinese American and Mexican American families, and exploring the parental perceptions of children's bilingual language learning. Further, the present study examines the relations among parental perceptions of bilingualism, home language and literacy practices, and home language oral proficiency. Data were collected from a total of 41 Mexican American and 91 Chinese American low-income immigrant families with DLLs ages 50-88 months who had been recruited from Head Start programs and state-funded preschools in Northern California when the children were 3-4 years old. Information about shared reading frequency, home language exposure and usage, and parental perceptions of bilingualism was collected through parental interviews, and DLLs' home language oral proficiency was individually assessed. No significant difference in home language oral proficiency was observed between the two groups. Principal Components Analysis on the parental perceptions of bilingualism measure revealed two components, "Importance of Being Bilingual" and "English over Bilingualism." Stepwise regression analysis results show that "Importance of Being Bilingual" was associated with children's home language oral proficiency after controlling for culture, child age, the frequency of home language shared book reading, and child home language exposure and use. The results show that parents' positive beliefs toward bilingualism are related to the children's use of that language and their children's language outcomes. Implications and suggestions for home language and literacy support for DLLs are discussed.

Associations of physical activity and cognitive function with gross motor skills in preschoolers: Cross-sectional study.

Gross motor development in the preschool phase depends on several factors that remain poorly understood. This study aimed to investigate whether level of habitual physical activity (HPA) and global cognitive function (CF) can be used as predictors of gross motor skills in Brazilian preschoolers and to verify their possible mediators. A cross-sectional study was conducted with 166 children, aged 3-5 years. Gross motor skills, HPA, CF and possible mediators (e.g., sex, prematurity) were evaluated. Preschoolers with little HPA, low CF, and girls were more likely to have gross motor performance below expected, but female gender did not mediate HPA or CF. Therefore, HPA and CF, in addition to females, may be independent predictors of delayed gross motor skills in Brazilian preschoolers.

Association of muscular strength with total and central adiposity in adolescents with intellectual disability.

BACKGROUND: It has been established that for youth without disabilities, muscular strength (MS) is negatively associated with total and central adiposity. However, this relationship has not been clearly established for youth with intellectual disability (ID). The purpose of this study was to examine the association of MS with total and central adiposity in adolescents with ID. METHOD: Participants were 59 adolescents (40 males and 19 females: age 16.29 ± 1.66 years) with ID. Total and central adiposity were evaluated with dual-energy x-ray absorptiometry (DXA), body mass index (BMI), BMI z-score, waist circumference (WC), and conicity index (C-index). MS was evaluated with the score on the Bruininks-Oseretsky Test of Motor Proficiency (range, 0 to 42, with higher scores indicating better performance). Sex-specific maturity offset equations were used to evaluate somatic maturity. Spearman's correlation coefficients and sequential multiple regression were used to examine associations between MS and adiposity. RESULTS: Muscular strength score was negatively associated with BMI (sr = -0.32; P < 0.05), percent body fat (%BF; total, trunk, android and gynoid regions) (sr = -0.51 to -0.58; P < 0.01), and android-to-gynoid fat ratio (sr = -0.29; P < 0.05). After control for somatic maturity and sex, regression analysis indicated that MS score explained 10%-17% of the variance in BMI, BMI z-score, %BF (total, trunk, android and gynoid regions), WC, C-index and android-to-gynoid fat ratio. CONCLUSIONS: These findings suggest that MS is associated with DXA- and anthropometric-determined total and central adiposity among adolescents with ID.

A Pilot Group-Based Lifestyle Intervention to Promote Weight Loss Among Mexican Immigrants.

Mexican Americans are at increased risk for obesity upon immigration to the U.S., increasing their risk for diabetes, cardiovascular disease, and cancer. Our pilot individual lifestyle intervention culturally tailored for Mexican Americans, COMIDA (Consumo de Opciones Más Ideales De Alimentos) (Eating More Ideal Food Options), showed promising results. This paper presents outcomes from the group-based version of COMIDA. 129 overweight/obese Mexican Americans were enrolled in 'Group COMIDA'. Participants' weight (primary outcome), dietary intake and nutrition knowledge (secondary outcomes) were assessed pre- and post-intervention. Seventeen percent of participants experienced 5% weight loss at follow-up. Post-intervention, participants consumed more fruit and vegetables and fewer sweets and fried foods. A group-based, culturally adapted lifestyle intervention may be a more cost-effective approach than individual interventions to improve dietary behavior among underserved populations, though additional modifications may be considered to increase the intervention's effectiveness in promoting significant weight loss.

Discrimination, reliability, sensitivity, and specificity of metric-based assessment of an unstable pertrochanteric 31A2 intramedullary nailing procedure performed by experienced and novice surgeons.

INTRODUCTION: Identifying objective performance metrics for surgical training in orthopedic surgery is imperative for effective training and patient safety. The objective of this study was to determine if an internationally agreed, metric-based objective assessment of video recordings of an unstable pertrochanteric 31A2 intramedullary nailing procedure distinguished between the performance of experienced and novice orthopedic surgeons. MATERIALS AND METHODS: Previously agreed procedure metrics (i.e., 15 phases of the procedure, 75 steps, 88 errors, and 28 sentinel errors) for a closed reduction and standard cephalomedullary nail fixation with a single cephalic element of an unstable pertrochanteric 31A2 fracture. Experienced surgeons trained to assess the performance metrics with an interrater reliability (IRR) > 0.8 assessed 14 videos from 10 novice surgeons (orthopaedic residents/trainees) and 20 videos from 14 experienced surgeons (orthopaedic surgeons) blinded to group and procedure order. RESULTS: The mean IRR of procedure assessments was 0.97. No statistically significant differences were observed between the two groups for Procedure Steps, Errors, Sentinel Errors, and Total Errors. A small number of Experienced surgeons made a similar number of Total Errors as the weakest performing Novices. When the scores of each group were divided at the median Total Error score, large differences were observed between the Experienced surgeons who made the fewest errors and the Novices making the most errors (p < 0.001). Experienced surgeons who made the most errors made significantly more than their Experienced peers (p < 0.003) and the best performing Novices (p < 0.001). Error metrics assessed with Area Under the Curve demonstrated good to excellent Sensitivity and Specificity (0.807-0.907). DISCUSSION: Binary performance metrics previously agreed by an international Delphi meeting discriminated between the objectively assessed video-recorded performance of Experienced and Novice orthopedic surgeons when group scores were sub-divided at the median for Total Errors. Error metrics discriminated best and also demonstrated good to excellent Sensitivity and Specificity. Some very experienced surgeons performed similar to the Novice group surgeons that made most errors. CONCLUSIONS: The procedure metrics used in this study reliably distinguish Novice and Experienced orthopaedic surgeons' performance and will underpin quality-assured novice training.

Impact of United States 2017 Immigration Policy changes on missed appointments at two Massachusetts Safety-Net Hospitals.

INTRODUCTION: Studies have shown mixed findings regarding the impact of immigration policy changes on immigrants' utilization of primary care. METHODS: We used a difference-in-differences analysis to compare changes in missed primary care appointments over time across two groups: patients who received care in Spanish, Portuguese, or Haitian Creole, and non-Hispanic, white patients who received care in English. RESULTS: After adjustment for age, sex, race, insurance, hospital system, and presence of chronic conditions, immigration policy changes were associated with an absolute increase in the missed appointment prevalence of 0.74 percentage points (95% confidence interval: 0.34, 1.15) among Spanish, Portuguese and Haitian-Creole speakers. We estimated that missed appointments due to immigration policy changes resulted in lost revenue of over $185,000. CONCLUSIONS: We conclude that immigration policy changes were associated with a significant increase in missed appointments among patients who receive medical care in languages other than English.

Externalizing problems mediate the relationship between motor proficiency and internalizing problems in children: An extension of the Environmental Stress Hypothesis.

The Environmental Stress Hypothesis (ESH) is a causal theoretical framework that provides a flexible context for understanding factors that mediate the relationship between low motor proficiency and internalizing problems in children. The purpose of the present study was to use the ESH framework to determine whether body mass index (BMI), physical activity levels, psychosocial health and physical health, self-efficacy, perceived social status, prosocial behavior and externalizing problems were potential mediators between motor proficiency and internalizing factors in a population of Brazilian children. 431 children aged 7- to 10 years (240 females, 191 males) participated in the study. The variables were measured with the Movement Assessment Battery for Children, 2nd ed. (MABC-2), the Pediatric Quality of Life Inventory (PedsQL), the Strengths and Difficulties Questionnaire (SDQ), the MacArthur Subjective Social Status Scale (MacArthur SSS), the Self-efficacy Sense Assessment Roadmap (RASAE), and the Physical Activity Questionnaire (PAQ). The results indicated a direct relationship between motor proficiency and internalizing problems in a population of Brazilian children, with externalizing problems being the only variable mediating that relationship. To the best of our knowledge, this is the first time that externalizing problems were tested in the context of the ESH. Understanding and evaluating potential mediators in the relationship between motor proficiency and internalizing problems using the ESH framework is essential to promote prevention policies and interventions for school-age children.

Does high-definition transcranial direct current stimulation change brain electrical activity in professional female basketball players during free-throw shooting?

Differentiated brain activation in high-performance athletes supports neuronal mechanisms relevant to sports performance. Preparation for the motor action involves cortical and sub-cortical regions that can be non-invasively modulated by electrical current stimulation. This study aimed to investigate the effect of high-definition transcranial direct current stimulation (HD-tDCS) on electrical brain activity in professional female basketball players during free-throw shooting. Successful free-throw shooting (n = 2,361) from seven professional female basketball players was analyzed during two experimental conditions (HD-tDCS cathodic and sham) separated by 72 h. Three spectral bio-markers, Power Ratio Index (PRI), Delta Alpha Ratio (DAR), and Theta Beta Ratio (TBR) were measured (electroencephalography [EEG] Brain Products). Multi-channel HD-tDCS was applied for 20 min, considering current location and intensity for cathodic stimulation: FCC1h, AFF5h, AFF1h (-0.5 mA each), and FCC5h (ground). The within EEG analyses (pre and post HD-tDCS) of frontal channels (Fp1, Fp2, F3, F4, FC1, FC3) for 1 second epoch pre-shooting, showed increases in PRI (p < 0.001) and DAR (p < 0.001) for HD-tDCS cathodic condition, and in TBR for both conditions (cathodic, p = 0.01; sham, p = 0.002). Sub-group analysis divided the sample into less (n = 3; LSG) and more (n = 4; MSG) stable free-throw-shooting performers and revealed that increases in pre to post HD-tDCS in PRI only occurred for the LSG. These results suggest that the effect of HD-tDCS may induce changes in slow frontal frequency brain activities and that this alteration seems to be greater for players demonstrating a less stable free-throw shooting performance.

Usability of a point-of-care diagnostic to identify glucose-6-phosphate dehydrogenase deficiency: a multi-country assessment of test label comprehension and results interpretation.

BACKGROUND: Point-of-care glucose-6-phosphate dehydrogenase (G6PD) testing has the potential to make the use of radical treatment for vivax malaria safer and more effective. Widespread use of G6PD tests as part of malaria case management has been limited, in part due to due concerns regarding product usability, user training, and supervision. This study seeks to assess how well end users can understand the Standard™ G6PD Test (SD Biosensor, Suwon, South Korea) workflow, result output, and label after training. This will ultimately help inform test registration and introduction. METHODS: Potential G6PD test users who provide malaria case management at three sites in Brazil, Ethiopia, and India were trained on the use of the SD Biosensor Standard G6PD Test and assessed based on their ability to understand the test workflow and interpret results. The assessment was done through a questionnaire, designed to assess product usability against key technical product specifications and fulfill regulatory evidence requirements. Any participant who obtained 85% or above correct responses to the questionnaire was considered to adequately comprehend how to use and interpret the test. RESULTS: Forty-five participants, including malaria microscopists, laboratory staff, nurses, and community health workers took part in the study. Seventy-eight percent of all participants in the study (35/45) obtained passing scores on the assessment with minimal training. Responses to the multiple-choice questions indicate that most participants understood well the test intended use, safety claims, and warnings. The greatest source of error regarding the test was around the correct operating temperature. Most test results were also read and interpreted correctly, with the haemoglobin measurement being a more problematic output to interpret than the G6PD measurement. CONCLUSIONS: These data results show how a standardized tool can be used to assess a user's ability to run a point-of-care diagnostic and interpret results. When applied to the SD Biosensor Standard G6PD Test, this tool demonstrates that a range of users across multiple contexts can use the test and suggests improvements to the test instructions and training that can improve product usability, increase user comprehension, and ultimately contribute to more widespread effective use of point-of-care G6PD tests. TRIAL REGISTRATION: NCT04033640.

Quantitative Metrics for Performance Monitoring of Software Code Analysis Accredited Testing Laboratories.

Modern sensors deployed in most Industry 4.0 applications are intelligent, meaning that they present sophisticated behavior, usually due to embedded software, and network connectivity capabilities. For that reason, the task of calibrating an intelligent sensor currently involves more than measuring physical quantities. As the behavior of modern sensors depends on embedded software, comprehensive assessments of such sensors necessarily demands the analysis of their embedded software. On the other hand, interlaboratory comparisons are comparative analyses of a body of labs involved in such assessments. While interlaboratory comparison is a well-established practice in fields related to physical, chemical and biological sciences, it is a recent challenge for software assessment. Establishing quantitative metrics to compare the performance of software analysis and testing accredited labs is no trivial task. Software is intangible and its requirements accommodate some ambiguity, inconsistency or information loss. Besides, software testing and analysis are highly human-dependent activities. In the present work, we investigate whether performing interlaboratory comparisons for software assessment by using quantitative performance measurement is feasible. The proposal was to evaluate the competence in software code analysis activities of each lab by using two quantitative metrics (code coverage and mutation score). Our results demonstrate the feasibility of establishing quantitative comparisons among software analysis and testing accredited laboratories. One of these rounds was registered as formal proficiency testing in the database-the first registered proficiency testing focused on code analysis.

Association between motor proficiency and oral health in people with intellectual disabilities.

BACKGROUND: People with intellectual disabilities (IDs) may be at increased risk of developing periodontal diseases and dental caries due to poor oral hygiene. Our aim was to investigate motor proficiency factors associated with presence of visible plaque and gingival bleeding in people with IDs. We were particularly interested in the level of dependence, manual coordination and fine manual control of people with ID, as well as the level of exhaustion of the primary caregiver. METHODS: In this cross-sectional study, 299 people with ID were evaluated for oral hygiene using the simplified Visible Plaque Index and for gum inflammation using the Gingival Bleeding Index. The Bruininks-Oseretsky Motor Proficiency Test assessed motor proficiency through fine manual control (fine motor integration and fine motor precision) and manual coordination (manual dexterity and upper limb coordination). The level of dependence was assessed by the Katz dependency index, and the caregiver was tested for exhaustion using the fatigue severity scale. Prevalence ratios [and 95% confidence intervals (CI)] were calculated using crude and adjusted Poisson regression with robust variance. RESULTS: The exhaustion of the caregiver was associated positively to visible plaque [prevalence ratio (PR) = 1.36; 95% CI 1.06-1.65]. For gingival bleeding, people with IDs that had better fine motor integration (PR = 0.49; 95% CI 0.33-0.75) and precision (PR = 0.50; 95% CI 0.26-0.94), as well as manual dexterity (PR = 0.62, 95% CI 0.49-0.77), presented better results. CONCLUSION: Poor oral hygiene and gum inflammation were associated with motor proficiency of people with IDs and caregivers' exhaustion. Interventions to improve the oral health of people with IDs should take into account such conditions.
