Nutrition Environment Gaps and Distribution Challenges in Rural Food Pantries During the COVID-19 Pandemic: A Mixed-Methods Study.

BACKGROUND: Food insecurity disproportionately affects low-income, racially marginalized, and rural communities. The COVID-19 pandemic led to higher demand for emergency food distribution, potentially impacting food pantry operations and services. Limited research exists assessing consumer nutrition environments of pantries in rural regions. OBJECTIVES: To assess the consumer nutrition environment of rural food pantries and report challenges and adaptations encountered during the pandemic. DESIGN: A mixed-methods, cross-sectional survey. PARTICIPANTS/SETTING: Nineteen food pantry representatives from California's San Joaquin Valley were surveyed between August 2020 and June 2021. Representatives were eligible if their pantry served the general population and was open at least once a week. Nine were church-based pantries, and 10 were from other settings. MAIN OUTCOME MEASURES: The Nutrition Environment Food Pantry Assessment Tool (NEFPAT) measured the nutrition food environment and scored pantries as bronze (0-15), silver (16-31), or gold (32-47) categories. Eleven items were developed to explore pandemic-related challenges. STATISTICAL ANALYSES PERFORMED: Independent χ2 tests assessed the relationship between the organization type and NEFPAT scores and food supply sources. Fisher's exact test explored associations between food pantry type, NEFPAT category, and challenges. Nonparametric tests were run on non-normally distributed data. Inductive content analysis was used to examine open-ended pandemic-related questions. RESULTS: The nutrition environment of most pantries was suboptimal, because no pantry scored in the "gold" category based on total NEFPAT scores (median, 18 of 47). No statistically significant differences were found in the NEFPAT scores by organization type. Most pantries did not provide healthy food nudges or culturally diverse foods. Key COVID-19 challenges encountered consisted of supply- and demand-side issues, including reduced personnel, capacity, and resources, and increased client quantity and demand for food. CONCLUSIONS: Assessing the nutrition environment of rural food pantries revealed gaps and strategies for improvement, including the use of healthy nudges and increasing the availability of culturally diverse foods.

Isokinetic trunk training on pain, disability, and strength in non-specific low back pain patients: A systematic review and meta-analysis.

BACKGROUND: Low back pain is one of the leading causes of disability globally, with a high economic and social burden. A decrease or imbalance in trunk strength has been associated with the occurrence of low back pain and its severity. Trunk strength training is helpful in the treatment of Non-specific low back pain (NSLBP) patients. However, we do not know the effects of trunk isokinetic training (IKT) on pain intensity, disability, and trunk strength. OBJECTIVE: This systematic review aimed to determine the effects of trunk IKT in NSLBP patients on pain intensity, disability, and trunk flexor and extensor isokinetic strength. METHODS: We searched PubMed, Web of Science, Scopus, CENTRAL, and PEDro, from January 2001 until March 2021 and updated to November 2022. Randomized controlled trials (RCTs) that investigated the effect of IKT in adult participants with NSLBP on pain intensity, disability, or isokinetic trunk strength were included. Mean difference (MD) and 95% confidence intervals (95% CI) were calculated for pain. Bias was assessed using the Cochrane risk of bias (RoB) tool and evidence certainty via Grading of Recommendations Assessment, Development and Evaluation (GRADE). RESULTS: Among 1750 retrieved articles, eight were included in this review. Meta-analysis comparing IKT (trunk isokinetic training, n= 134) with control groups (conventional exercises, n= 133) revealed that IKT decreases pain intensity (MD -1.50 (95% CI: -2.60; -0.39)) immediately post-intervention, and one month (MD -1.97 (95% CI: -2.92; -1.03)) and at six months follow-up (MD -2.48 (95% CI: -2.77; -2.19)), although with a very low to low quality according to the GRADE rating. Besides, IKT decreases disability and increases isokinetic trunk strength, but with scant evidence. CONCLUSIONS: Trunk IKT could be a novel clinical tool for pain management in patients with NSLBP, although evidence is scarce. In addition, few RCTs exist for IKT on disability or trunk isokinetic strength in patients with NSLBP. Therefore, further research on this topic is needed.

Cross-Cultural Adaptation and Initial Validation of Mi Niño: A Tool to Measure Food-Related Parenting Practices of Spanish-Speaking Parents with Young Children.

Background: Accurate measurement of food-related parenting practices is necessary to inform related interventions and program evaluation. Valid tools reflect cultural attributes that affect household food environments and feeding practices. Simple, unidirectional language adaptation approaches are insufficient to capture these attributes in assessment tools. My Child at Mealtime (MCMT) is a 27-item, validated, visually enhanced self-assessment tool to measure food-related parenting practices of low-income English-speaking parents of preschoolers. Objectives: The aim of this study was to describe the cross-cultural adaptation of MCMT into its Spanish version Mi Niño a la Hora the Comer (Mi Niño) and to establish its face validity, factor structure, and internal consistency. Methods: MCMT was adapted into its Spanish version after an iterative process that triangulated cognitive interviews with verification of conceptual equivalence by content experts to establish face validity and semantic equivalence. The resulting tool underwent confirmatory factor analysis to determine whether internal consistency was equivalent across the 2 versions. Results: Four rounds of cognitive interviews (n = 5, n = 6, n = 2, and n = 4, respectively) with Spanish-speaking women caregivers of children aged 3-5 y recruited from Head Start were conducted. Ten items were modified throughout the adaptation process. Modifications included improved clarity (6 items), comprehension (7 items), appropriateness (4 items), suitability (4 items), and usefulness (2 items) of text and/or accompanying visuals. Confirmatory factor analysis with a sample of Spanish-speaking caregivers (n = 243) resulted in 2 reliable factors representing "child-centered" (α = 0.82) and "parent-centered" (α = 0.87) food-related parenting practices. Conclusions: Face validity, semantic equivalence, and internal consistency of Mi Niño were established. This tool can be used in community settings to inform program content and measure changes in food-related parenting practices of Spanish-speaking parents and assist in setting food-related parenting goals. The next steps include exploring the correspondence of Mi Nino with mealtime behaviors observed through video recording.

Obesity Risk Assessment for Spanish-Speaking Immigrant Families with Young Children in the United States: Reliability and Validity with Nutrient Values.

The purpose is to examine validity and reliability for an obesity risk assessment tool developed in Spanish for immigrant families with children, 3-5 years old using an 8-week cross-sectional design with data collected over 1 year at Head Start and Special Supplemental Nutrition Program for Women, Infants and Children [WIC]. Parent/child dyads (206) provided a child obesity risk assessment, three child modified 24 h dietary recalls, three child 36+ h activity logs and one parent food behavior checklist. Main outcome measures were convergent validity with nutrients, cup equivalents, and diet quality and three assessments of reliability that included item difficulty index, item discrimination index, and coefficient of variation. Validity was demonstrated for assessment tool, named Niños Sanos. Scales were significantly related to variables in direction hypothesized [p ≤ 0.05]: Healthy Eating Index, fruit/vegetable cup equivalents, folate, dairy cup equivalents, vitamins D, ß-carotene, fiber, saturated fat, sugar, time at screen/ sleep/physical activity and parent behaviors. Three measures of reliability were acceptable. The addition of nutrient values as an analytical validation approach adds strength and consistency to previously reported Niños Sanos validation results using children's blood biomarkers and body mass index. This tool can be used by health professionals as an assessment of obesity risk in several capacities: (1) screener for counseling in a clinic, (2) large survey, (3) guide for participant goal setting and tailoring interventions, and (4) evaluation.

Complications of total temporomandibular joint replacement: a systematic review and meta-analysis.

The aim of this systematic review was to determine the most prevalent complications resulting from total temporomandibular joint (TMJ) replacement. An electronic search was performed using the Embase, LILACS, MEDLINE (via PubMed), SciELO, Scopus, and Web of Science databases up to June 2022. Prospective and retrospective clinical studies on patients who underwent TMJ replacement were included. Two reviewers performed the study selection, data extraction, and individual risk of bias assessment using the Joanna Briggs Institute Critical Appraisal Tools. The pooled prevalence of each complication was calculated through a proportion meta-analysis using the random-effects model. Twenty-eight studies met the eligibility criteria and were included in the review. All of the eligible studies had a low risk of bias. The results of the meta-analysis revealed that the most prevalent complication was paresis or paralysis of the facial nerve branches (7.8%; 95% confidence interval (CI) 2.6-15.1%, I2 = 94.5%), followed by sensory alterations (1.8%; 95% CI 0.6-4.9%, I2 = 88.8%), heterotopic bone formation (1.0%; 95% CI 0.1-2.5%, I2 = 75.8%), and infection (0.7%; 95% CI 0.1-1.6%, I2 = 22.7%). In conclusion, TMJ replacement has a low prevalence of complications, and most of them can be managed successfully.

Discapacidad funcional en pacientes con fibromialgia en un hospital en Lima, Perú

Introducción: La fibromialgia es un trastorno reumatológico caracterizado por dolor generalizado de localización imprecisa que afecta principalmente a mujeres. Se asocia a fatiga, ansiedad, depresión y la capacidad funcional de estos pacientes se ve afectada por la coexistencia de dichos trastornos. Métodos: Serie de casos de corte transversal con uso de datos secundarios de 126 pacientes con fibromialgia que acudieron a consultorio externo del servicio de reumatología de un hospital en Lima durante febrero de 2020. Se buscó determinar la frecuencia de discapacidad funcional y explorar factores asociados en pacientes con diagnóstico de fibromialgia con o sin depresión. La capacidad funcional y la presencia de síntomas depresivos fueron medidas mediante uso de escalas validadas. Se realizó un análisis multivariado de regresión logística múltiple para valorar si la depresión es un factor de riego independiente de discapacidad. Resultados: La edad tuvo una mediana de 53,5 (RIQ: 46-60) años y 122 participantes eran mujeres, además 42 (33,33%) pacientes presentaban depresión y 76 (60,32%) presentaban discapacidad funcional. En el análisis multivariado, se encontró que la depresión es un factor de riesgo independiente de discapacidad funcional luego de ajustar a diabetes, presencia de 3 o más comorbilidades, intensidad de fatiga y síntomas asociados [OR de 3.09 (1.24 - 7.70); p: 0.015]. Conclusiones: La depresión es un factor independiente para discapacidad funcional en pacientes con fibromialgia.

Background: Fibromyalgia is a rheumatological disorder characterized by generalized pain of imprecise localization that mainly affects women. It is associated with fatigue, anxiety, depression, and functional capacity is greatly affected by the coexistence of these disorders. Methods: It is a series of cross-sectional cases, using secondary data from 126 patients with fibromyalgia who attended the outpatient clinic of a hospital at Lima at the rheumatology service during February 2020. We try to determine the frequency of functional disability and explore associated factors in patients diagnosed with fibromyalgia with or without depression. Functional capacity and the presence of depressive symptoms were measure by validated scales. A multivariate multiple logistic regression analysis was performed to assess whether depression is an independent risk factor for disability. Results: The age had a median of 53.5 (IQR: 46-60) years, 122 participants were women. In addition, 42 (33.33%) patients had depression and 76 (60.32%) patients had functional disability. In the multivariate analysis, it was found that depression is an independent risk factor for functional disability after adjusting for diabetes, presence of 3 or more comorbidities, intensity of fatigue and associated symptoms [OR 3.09 (1.24 - 7.70); p: 0.015]. Conclusions: Depression is an independent factor for functional incapacity in patients with fibromyalgia.

A Cross-Sectional Analysis of Food Perceptions, Food Preferences, Diet Quality, and Health in a Food Desert Campus.

The sensory properties of foods guide food choices and intake, importantly determining nutritional and health status. In communities that have inconsistent access to nutritious foods, such as food deserts, food taste perceptions and preferences have yet to be explored. The purpose of this study was to examine how taster status (supertaster vs. non-taster) and food security status (high or marginal vs. low or very low) influences food taste intensities, food preferences and perceptions, and diet quality in a cohort of students from a food desert campus in the Central Valley of California. Moreover, the complex relationship of socioeconomic status, race/ethnicity, and sex on cardiometabolic and cognitive health warrants further examination. Two hundred fifty participants (aged 18-24 years) living in a food desert campus were recruited in 2018 for this cross-sectional study where participants underwent taste tests on selected fruits, vegetables, and nuts, and clinical tests (anthropometrics, blood glucose, blood pressure, and endothelial function), cognitive function tests (memory and attention), diet quality assessment (Healthy Eating Index (HEI)), and food preference and perception assessments. Food taste intensities were influenced by sex with bitter and umami taste intensities of several foods being perceived more intensely by males. Moreover, food liking was largely influenced by ethnicity with Hispanics having higher liking ratings for several foods compared with non-Hispanics. Both, Hispanics and females, had higher total fruit HEI scores and lower attention scores than non-Hispanics and males, respectively. Females also had lower blood pressure, reactive hyperemia index, and fasting blood glucose. Food-insecure individuals rated cost and convenience as more important factors for overall food consumption and had lower attention scores than those with higher food-security status. Future research should consider the complex interactions of factors such as taste and flavor perception, sex, ethnicity, prior exposure to foods, and other environmental factors when studying food preferences and health in young adults.

Selection of patients for percutaneous closure in nonlacunar cryptogenic stroke associated with patent foramen ovale. Data from the NORDICTUS cooperative registry.

INTRODUCTION: There is an extending use of percutaneous closure of patent foramen ovale (PFO) as therapy for PFO-associated cryptogenic strokes. The aim of our study was to investigate the clinical practice of percutaneous closure of PFO and to analyse the variables for decision-making on the selection of patients for this procedure. METHOD: A prospective observational multicentric survey was conducted using all the cases of cryptogenic stroke/transient ischaemic attack associated with PFO recorded in the NORDICTUS hospital registry during the period 2018-2021. Clinical data, radiological patterns, echocardiogram data and factors related to PFO-associated stroke (thromboembolic disease and paradoxical embolism criteria) were recorded. The indication for closure was analysed according to age (≤/> 60 years) and the characteristics of the PFO. RESULTS: In the group ≤ 60 years (n = 488), 143 patients (29.3%) underwent PFO closure. The most influential variables for this therapy were detection of a high-risk PFO (OR 4.11; IC 2.6-6.5, P < .001), criteria for paradoxical embolism (OR 2.61; IC 1.28-5.28; P = .008) and previous use of antithrombotics (OR 2.67; IC 1.38-5.18; P = .009). In the > 60 years group (n = 124), 24 patients had PFO closure (19%). The variables related to this option were history of pulmonary thromboembolism, predisposition to thromboembolic disease, paradoxical embolism criteria, and high-risk PFO. CONCLUSIONS: The detection of a high-risk PFO (large shunt, shunt with associated aneurysm) is the main criterion for a percutaneous closure-based therapy. Other conditions to consider in the eligibility of patients are the history of thromboembolic disease, paradoxical embolism criteria or the previous use of antithrombotics.

The loss of a child, bereavement and the search for meaning: A systematic review of the most recent parental interventions.

The loss of a child is considered one of the most tragic experiences that parents can go through. The present systematic review aims to compile the most recently published interventions in bereavement support for these parents, being particularly interested in those made from a meaning-centered approach. The search for the units of analysis was guided by the standards of the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) Statement and was entered in Web of Science, Scopus and EBSCO, obtaining a total of 485 papers of which 21 have been included in this article. The results found are heterogeneous in terms of the type of intervention used and results, but they all seem to have something in common: the lack of research and reliable interventions that exist for this population. With this systematic review we intend to achieve a better understanding of these parents' needs and to highlight the enormous work that still remains ahead in order to make their bereavement experience a little less devastating.

Spine stabilization exercises are not superior to flexion exercises for ultrasound-detected muscle thickness changes in patients with chronic low back pain and lumbar spondylolisthesis / Los ejercicios de estabilización de la columna vertebral no son superiores a los ejercicios de flexión para los cambios de grosor muscular detectados por ecografía, en pacientes con lumbalgia crónica y espondilolistesis lumbar

Abstract: Introduction: exercise programs can reduce pain and improve functionality in patients with degenerative spondylolisthesis and chronic low back pain. However, there is still no consensus surrounding the superiority of any specific routine for exercise-induced trophic changes of lumbar muscles. The aim was to compare the changes in the primary lumbar stabilizing muscle thickness after spine stabilization exercises and flexion exercises in patients with spondylolisthesis and chronic low back pain. Material and methods: prospective, longitudinal and comparative study was carried out. Twenty-one treatment-naive patients with a diagnosis of both chronic low back pain and degenerative spondylolisthesis over the age of 50 were included. A physical therapist taught participants either spine stabilization exercises or flexion exercises to execute daily at home. The thickness of the primary lumbar muscles was measured through ultrasound (at rest and contraction) at baseline and three months. A Mann-Whitney U test and Wilcoxon signed-rank test were performed for comparisons, and Spearman's rank correlation coefficients were calculated for associations. Results: we did not find statistically between the exercise programs: all patients presented significant changes in the thickness of the multifidus muscle but in none of the other evaluated muscles. Conclusion: there is no difference between spine stabilization exercises and flexion exercises after three months in terms of the changes in muscle thickness evaluated by ultrasound.

Resumen: Introducción: el ejercicio reduce el dolor y mejora la funcionalidad en pacientes con dolor crónico lumbar y espondilolistesis degenerativa. Sin embargo, no existe a la fecha un consenso sobre la superioridad de algún programa de ejercicio para inducir cambios tróficos de los músculos estabilizadores lumbares, por lo que el objetivo fue comparar el trofismo de estos músculos mediante ultrasonido, con dos programas de ejercicio distintos: estabilización vertebral versus ejercicios flexores. Material y métodos: estudio prospectivo, longitudinal y comparativo, en veintiún pacientes mayores de 50 años, con dolor crónico lumbar y espondilolistesis degenerativa. Se entrenó a los pacientes para la ejecución diaria de ejercicio: estabilización lumbar o ejercicios flexores, los cuales fueron asignados por aleatorización como parte de un ECA en desarrollo. El trofismo muscular fue evaluado mediante ultrasonido al inicio y a tres meses. Las pruebas de U de Mann-Whitney y prueba de Wilcoxon se usaron para comparaciones entre grupos y para correlaciones se usaron los coeficientes de correlación de Spearman. Resultados: todos los pacientes presentaron ganancia en el trofismo de los músculos multífidos a tres meses, pero sin diferencias entre grupos de tratamiento. No se detectaron cambios significativos en el resto de los músculos evaluados. Conclusión: no encontramos diferencia significativa entre los ejercicios de estabilización lumbar y los ejercicios flexores, a tres meses de seguimiento, en términos de los cambios tróficos medidos por ultrasonido de los músculos estabilizadores lumbares.

Collecting, Using, and Reporting Race and Ethnicity Information: Implications for Research in Nutrition Education, Practice, and Policy to Promote Health Equity.

This report will describe approaches for collecting, analyzing, and reporting race and ethnicity information in nutrition education and behavior research, practice, and policy to advance health equity. Race and ethnicity information is used to describe study participants and compare nutrition and health-related outcomes. Depending on the study design, race and ethnicity categories are often defined by the research question or other standardized approaches. Participant self-reported data are more acceptable than researcher adjudicated identification data, which can add bias and/or error. Valid methods to collect, use, and report race and ethnicity information are foundational to publication quality, findings of value, contribution to the knowledge base, and health equity.

A Systematic Review of Literature on the Representation of Racial and Ethnic Minority Groups in Clinical Nutrition Interventions.

The racial and ethnic disparities in diet-related chronic diseases are major concerns. This systematic review examines the extent to which diet-induced changes in health outcomes, such as cardiometabolic, inflammation, cancer, bone health, and kidney function outcomes, etc., have been reported and discussed by race or ethnicity in randomized trials with 2 or more diet arms that recruited both minority and non-Hispanic White groups. Databases (i.e., PubMed, Cochrane Library, and Web of Science) were searched up to August 2021. Thirty-four studies that discussed effects of defined dietary interventions on health outcomes by racial or ethnic minority group compared with non-Hispanic Whites were included in the systematic review (PROSPERO registration number: CRD42021229256). Acute trials and those with 1 diet arm that accounted for race or ethnicity in their analyses and studies that focused on a single racial or ethnic group were discussed separately. Most studies were conducted in Black compared with White adults testing effects of energy restriction, macronutrient modification, sodium reduction, or variations of the Dietary Approaches to Stop Hypertension (DASH) diet on cardiometabolic outcomes. There was limited focus on other minority groups. Evidence suggests greater blood pressure reduction for Black adults compared with Whites particularly with DASH (or similar) diets. Overall, there was limited consideration for group-specific eating patterns and diet acceptability. Overall risk of bias was low. With emerging precision nutrition initiatives that aim to optimize metabolic responses in population subgroups through tailored approaches, it is imperative to ensure adequate representation of racial and ethnic subgroups for addressing health disparities. Factors that help explain variability in responses such as socioecological context should be included and adequately powered. Given the racial and ethnic disparities in chronic diseases, studying the adoption, maintenance, and effectiveness of dietary interventions on health outcomes among different groups is critical for developing approaches that can mitigate diet-related health disparities.

Protease Inhibitors from Plants as Therapeutic Agents- A Review.

Plant-based diets are a great source of protease inhibitors (PIs). Two of the most well-known families of PIs are Bowman-Birk inhibitors (BBI) and Kunitz-type inhibitors (KTI). The first group acts mainly on trypsin, chymotrypsin, and elastase; the second is on serine, cysteine, and aspartic proteases. PIs can retard or inhibit the catalytic action of enzymes; therefore, they are considered non-nutritional compounds; nevertheless, animal studies and cell line experiments showed promising results of PIs in treating human illnesses such as obesity, cardiovascular diseases, autoimmune diseases, inflammatory processes, and different types of cancer (gastric, colorectal, breast, and lung cancer). Anticarcinogenic activity's proposed mechanisms of action comprise several inhibitory effects at different molecular levels, i.e., transcription, post-transcription, translation, post-translation, and secretion of cancer cells. This work reviews the potential therapeutic applications of PIs as anticarcinogenic and anti-inflammatory agents in human diseases and the mechanisms by which they exert these effects.

Effects of eccentric exercise on muscle architecture in adults: a systematic review / Efectos del ejercicio excéntrico en la arquitectura muscular en adultos: una revisión sistemática

SUMMARY: The purpose of this systematic review was to determine the effects of eccentric training on muscle architecture in the adult population. Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) statements were followed using keywords associated with architecture muscular and eccentric training. Four databases were used: PubMed, Scopus, SPORTDiscus and Web of Science. Methodological quality was assessed using the PEDro scale. A total of 1260 articles were retrieved, 18 included in this review. The parameters most frequently evaluated in the studies consulted were pennation angle (PA), fascicle length (FL), and muscle thickness (MT). These were assessed mainly in lower limb muscles such as biceps femoris long head (BFlh), vastus lateralis (VL), medial gastrocnemius (MG) and lateral gastrocnemius (LG), respectively. Eccentric training for at least four weeks generates adaptations in these parameters, mainly by increasing MT with FL and decreasing PA, determining muscle function. These results provide evidence on the effects of eccentric training on muscle architecture, which could be helpful to prevent injuries and favor muscle recovery processes.

RESUMEN: El propósito de esta revisión sistemática fue determinar los efectos del entrenamiento excéntrico sobre la arquitectura muscular en la población adulta. Se siguieron las recomendaciones del Ìtems de referencia para publicar Revisiones Sistemáticas y Metaanálisis (PRISMA) utilizando palabras clave asociadas con la arquitectura muscular y el entrenamiento excéntrico en cuatro bases de datos: PubMed, Scopus, SPORTDiscus y Web of Science. La calidad metodológica se evaluó mediante la escala PEDro. Se encontró un total de 1260 artículos, del los cuales, 18 fueron incluidos en esta revisión. Los parámetros más frecuentemente evaluados en los estudios fueron el ángulo de penación (AP), la longitud del fascículo (LF) y el grosor muscular (Gm). Estos fueron evaluados principalmente en músculos de los miembros inferiores como la cabeza larga del bíceps femoral (CLBf), el vasto lateral (VL), el gastrocnemio medial (GM) y el gastrocnemio lateral (GL), respectivamente. El entrenamiento excéntrico durante al menos cuatro semanas genera adaptaciones en estos parámetros, principalmente aumentando el GM con la LF y disminuyendo el AP, determinando de esta manera la función muscular. Estos resultados aportan evidencias sobre los efectos del entrenamiento excéntrico en la arquitectura muscular, que podrían ser útiles para prevenir lesiones y favorecer los procesos de recuperación muscular.

Progression of a series of patients with relapsing-remitting multiple sclerosis treated for 7 years with natalizumab using the "no evidence of disease activity" parameter.

INTRODUCTION: The safety and effectiveness of natalizumab in patients with relapsing-remitting multiple sclerosis (RRMS) has been demonstrated in clinical trials. However, due to the limitations of these trials, it is important to know how the condition behaves under long-term clinical practice conditions. OBJECTIVE: To determine the long-term effectiveness of natalizumab in patients with RRMS by means of annual evaluation of the "no evidence of disease activity" (NEDA) parameter, which includes number of relapses, disability (measured with the Expanded Disability Status Scale), and brain MRI parameters. PATIENTS AND METHODS: We performed a retrospective study of patients with RRMS from 3 centres who were treated with one or more doses of natalizumab. Each year, we evaluated NEDA status and safety based on the percentage of patients who discontinued treatment with natalizumab and experienced adverse reactions. RESULTS: The study included 89 patients, most of whom received treatment for 2 to 4 years, with a follow-up period of up to 7 years. Natalizumab significantly reduces the radiological and clinical progression of the disease, as well as the annual rate of relapses. The NEDA parameter demonstrates the effectiveness of the drug, with values of 75.28% for year one and 66.67% for year 7. Twenty-five patients (28.1%) dropped out after a median of 4 years. Fourteen of these patients (56%) dropped out due to the appearance of anti-JC virus antibodies, either in isolation or associated with another cause. Four dropouts (16%) were due to treatment ineffectiveness, with one patient dying due to progressive multifocal leukoencephalopathy. CONCLUSIONS: Natalizumab is highly effective as measured by the NEDA long-term remission parameter.

Development of an online curriculum for California early care and education providers on healthy beverages.

BACKGROUND: Children's consumption of sugar-sweetened beverages is associated with obesity, diabetes, and dental decay. California's Healthy Beverages in Child Care Act (AB 2084) requires all licensed child care centers and family child care homes to comply with healthy beverages standards, however many licensed providers in California are unaware of the law and few are fully compliant with the law's requirements. The aim of the current project is to describe the development of a self-paced online training on best practices and implementation of AB 2084 in English and Spanish for family child care home and child care center providers; and to evaluate the feasibility, defined as being accessible, acceptable, and satisfactory to providers, of this new online course. METHODS: The project was broken into two main stages: (1) development of the online course; and (2) evaluation of the final online course. The first stage was completed in five phases: (1) identify relevant course content and develop narration script; (2) conduct in-person focus groups with child care providers to review and edit the content; (3) adapt course content and translate for Spanish-speaking providers; (4) build the online course and resources; and (5) pilot online course and evaluate accessibility. The second stage, evaluation of the acceptability and satisfaction of the final course was rated on a Likert scale from 1 to 4; the evaluation was completed as part of a larger randomized control trial with 43 child care providers. The course features four key requirements of AB 2084 as the main sections of the course (milk, sweetened beverages, juice, and water), plus background information about beverages and children's health, special topics including caring for children with special needs, family engagement, written policies, and child engagement. RESULTS: The child care providers who completed the evaluation found the online training was easily understandable (median(Q1,Q3,IQR) = 4 (4,4,0)), included new information (3 (1, 3, 4)), provided useful resources (4(4,4,0)), and was rated with high overall satisfaction (3 (1, 3, 4)). CONCLUSION: Online training in English and Spanish designed for child care providers is a feasible medium to deliver important health messages to child care providers in an accessible, acceptable, and satisfactory manner.
