RESUMO
BACKGROUND: College students have a high prevalence of food insecurity, and descriptive reports suggest even higher rates at minority-serving institutions than those at predominantly White institutions. These institutional inequities in food insecurity among college students based on minority designation may have shifted owing to the COVID-19 pandemic. OBJECTIVES: We aimed to compare the prevalence of food insecurity between students at minority serving and predominantly White institutions during 3 phases: prepandemic [Fall 2019-Spring 2020 (February 2020)], earlier pandemic (Fall 2020-Spring 2021), and later pandemic (Fall 2021-Spring 2022). METHODS: Our study included repeated cross-sectional samples from the American College Health Association-National College Health Assessment III (N = 287,221 students, 354 institutions). We performed multivariable Poisson regression with cluster-robust SEs to estimate associations between institutional minority designation and food insecurity, with 1 model for each pandemic phase. RESULTS: Students attending minority serving compared with predominantly White institutions had a higher prevalence of food insecurity overall (42% compared with 37%) and within each pandemic phase. After adjusting for sociodemographic and institutional characteristics, students at minority serving institutions had 23% higher food insecurity prevalence during the prepandemic phase than students at predominantly White institutions (95% confidence interval: 1.14, 1.32). Associations were null for earlier and later pandemic phases. CONCLUSIONS: Lower institutional inequities in food insecurity after the onset of the pandemic may reflect more students returning home as well as an increase in social safety net programs. Regardless of cause, the high prevalence of food insecurity among students, especially at minority serving institutions, underscores the importance of addressing food insecurity at postsecondary campuses.
RESUMO
Introduction: Low-income immigrants who are eligible to participate in the Supplemental Nutrition Assistance Program (SNAP) participate at lower rates compared to non-immigrants. Immigrant households may be more likely to participate in SNAP if they live in areas with policies that integrate them into society and protect them from deportation. Methods: Data on low-income immigrant households came from the 2019 American Community Survey (N = 87,678). The outcome was whether any household member received SNAP in the previous 12 months. Immigrant policy exposures came from two sources: the State Immigration Policy Resource, which includes 18 immigrant criminalizing and integrating policies, and a database that identified 'sanctuary policies' (SP), which we summarized at the county level. Multivariable logistic regression adjusted for person/household-level and area-level confounders. Results: Living in a jurisdiction with a SP was associated with 21% higher odds of enrolling in SNAP compared to living in a jurisdiction without a SP (adjusted odds ratio [aOR] 1.21, 95% CI=1.11,1.31). Relative to the least immigrant friendly states, living in the most immigrant-friendly states was associated with 16% higher odds of SNAP enrollment (aOR=1.16, 95%CI=1.06-1.28). When SP and state-level immigrant friendly policy environment were cross-classified, SNAP participation was 23% and 26% higher for those living in jurisdictions with one- and both- exposures, respectively, relative to those with neither (aOR 1.23; CI 1.12,1.36; aOR 1.26; CI 1.15,1.37). Conclusions: Many at high risk of food insecurity - including immigrants and citizens in households with immigrants - are eligible for SNAP but under-enroll. Policies that welcome and safeguard immigrants could reduce under enrollment.
RESUMO
INTRODUCTION: Water insecurity-the inability to access and benefit from affordable, reliable and safe water for basic needs-is a considerable global health threat. With the urgent need to target interventions to the most vulnerable, accurate and meaningful measurement is a priority. Households use diverse strategies to cope with water insecurity; however, these have not been systematically characterised nor measured. The Food Insecurity Coping Strategies Index has been insightful for targeting nutrition interventions to the most vulnerable. As a first step towards creating an analogous scale for water, this study characterises the largest empirical data set on water insecurity coping strategies and proposes guidance on measuring it using a novel toolkit. METHODS: Open-ended responses on water insecurity coping (n=2301) were collected across 11 sites in 10 low- and middle-income countries in the Household Water InSecurity Experiences (HWISE) Scale validation study. Responses were characterised and compared with behaviours identified in the literature to construct an instrument to systematically assess coping. RESULTS: We identified 19 distinct strategies that households used when experiencing water insecurity. These findings, paired with prior literature, were used to develop a Water Insecurity Coping Strategies Assessment Toolkit with guidance on its piloting to assess coping prevalence, frequency and severity. CONCLUSIONS: The widespread occurrence of water insecurity coping strategies underscores the importance of understanding their prevalence and severity. The Water Insecurity Coping Strategies Assessment Toolkit offers a comprehensive approach to evaluate these strategies and inform the design and monitoring of interventions targeting those most vulnerable to water insecurity.

In celiac disease (CD) there is a state of hypercoagulability and multiple factors have been found that may be involved. Cases of association of CD and antiphospholipid síndrome (APS) have been described and several observational studies have found an increase in antiphospolipid antibodies (AAF) in patients with CD, so both entities may be interrelated, increasing the risk of thrombotic events. A descriptive case of a patient who is simultaneusly diagnosed with CD and APS is presented.
RESUMO
Resumen Objetivo: describir los aspectos moleculares y celulares de la respuesta inmune frente a SARS-CoV-2; y las repercusiones clínicas, producto de mecanismos inmunes. Introducción: la aparición de una neumonía atípica en China, en diciembre de 2019, provocó un confinamiento global. El agente responsable de esta enfermedad fue nombrado por el Comité Internacional de Taxonomía de Virus como SARS-CoV-2, y la enfermedad que produce fue denominada COVID-19 por la OMS el 11 de febrero del 2020. Metodología: para este estudio descriptivo se indagó en la base de datos de Pubmed, Science, Nature, The Lancet, The New England Journal of Medicine, medRxiv y Google académico; cuyos descriptores utilizados fueron COVID-19, 2019-nCoV, SARS-CoV-2, linfocitos, anticuerpos e inmunidad; incluyendo en la revisión 130 estudios. Resultados: las manifestaciones clínicas más frecuentes que produce SARS-CoV-2 son: fiebre, tos seca y fatiga; siendo los individuos ancianos que presentan con mayor frecuencia complicaciones como el síndrome de distrés respiratorio agudo, arritmias, fallo cardíaco agudo y shock séptico. Se identificó descensos significativos de las células NK, linfocitos B, linfocitos T CD4+ y CD8+ en sangre periférica en pacientes con cuadros moderados y severos de COVID-19. Discusión: Las células NK y macrófagos se encargan de la contención y eliminación viral en las primeras etapas de la infección por SARSCoV-2. No está claro la relevancia de la respuesta humoral en la contención, y eliminación de SARS-CoV-2. La respuesta de linfocitos T citotóxicos es esencial para la completa resolución de la infección por SARS-CoV-2, ya que logran la eliminación de las células infectadas. No existe un tratamiento antiviral específico recomendado para COVID-19, y actualmente no existe vacuna disponible.
Abstract Objective: To describe the molecular and cellular aspects of the immune response against SARS-CoV-2 and the clinical repercussions resulting from inefficient immune mechanisms. Introduction: The emergence of an atypical pneumonia in China in December 2019 led to a global confinement. The agent responsible for this new disease was named SARS-CoV-2 by the International Committee on Taxonomy of viruses, and the disease it produces was named COVID-19 by the WHO on February 11, 2020. Methodology: For this descriptive study we researched the databases of Pubmed, Science, Nature, The Lancet, The New England Journal of Medicine, medRxiv and Google Scholar; which descriptors used were: COVID-19, 2019-nCoV, SARS-CoV-2, lymphocytes, antibodies and immunity; including 130 studies in the review. Results: The most common clinical manifestations produced by SARS-CoV-2 are: fever, dry cough and fatigue, being the elderly people who are mostly having complications such as acute respiratory distress syndrome, arrhythmias, acute heart failure and septic shock. Significant decreases in NK cells, B lymphocytes, CD4+ and CD8+ T lymphocytes were identified in peripheral blood in patients with moderate and severe COVID-19 conditions. Discussion: NK cells and macrophages are responsible for viral containment and elimination in the early stages of SARS-CoV-2 infection. The relevance of the humoral response in the containment and elimination of SARS-CoV-2 is unclear. The cytotoxic T lymphocyte response is essential for the complete resolution of SARS-CoV-2 infection, as they achieve the elimination of infected cells. There is no specific antiviral treatment recommended yet for COVID-19, and there is currently no vaccine available.

ABSTRACT Objective. To evaluate the effect of three diets on the growth of juvenile common snook (Centropomus undecimalis) maintained in freshwater ponds. Materials and methods. 108 juvenile of common snook were homogenous and randomly distributed in a pond, divided into 9 corrals of 50 m2. Three diets were applied (D1: commercial food for trout, 45% protein; D2: commercial food for cobia, 50% protein and D3: fresh fish, 17.52% protein). The experimental treatments were assigned in triplicate and diets were supplied in two daily doses. Biometrics were performed every 20 days to assess: weight, size, Length-Weight correlation, Feed Conversion Factor (FCA), Condition Factor (K), Specific Growth Rate (SGR) and survival; during 120 days. The results were evaluated with a one-way ANOVA, when differences (p<0.05) were found the means were compared by test Median Mood, otherwise a pos-hoc test was performed (Tukey HSD). Results. Applying the test of Mood Median significant differences were found, showing the highest growth with D2, where values of SGR=0.65±0.09 g/day; FCA=3.76 and K=0.81±0.06. Survival was D1=51.4%, D2=50% and D3=77.8% without inferring statistically among the different diets. Conclusions. The culture of this species in freshwater ponds with commercial food for cobia, is viable in terms of growth and weight gain.
RESUMEN Objetivo. Evaluar el efecto de tres dietas sobre el desempeño de juveniles de róbalo (Centropomus undecimalis) mantenidos en estanques de agua dulce. Materiales y métodos. 108 juveniles de róbalo fueron distribuidos homogénea y aleatoriamente en un estanque dividido en 9 corrales de 50 m2. Se suministraron tres dietas (D1: alimento comercial para truchas, 45% de proteína; D2: alimento comercial para cobia, 50% de proteína y D3: pescado fresco, 17.52% de proteína). Los tratamientos experimentales fueron asignados por triplicado y se les suministró cada dieta en dos dosis diarias. Se realizaron biometrías cada 20 días evaluando: peso, talla, relación Longitud-Peso, Factor de Conversión Alimenticia (FCA), Factor de Condición (K), Tasa Específica de Crecimiento (SGR) y supervivencia final; durante 120 días. Los resultados fueron evaluados con un ANOVA a una vía, cuando no se encontraron diferencias (p>0.05) las medias fueron comparadas mediante la prueba de la Mediana de Mood. En caso de significación estadística del ANOVA, se aplicó la prueba de comparación múltiple de Tukey HSD. Resultados. Se encontraron diferencias estadísticas entre los tratamientos, mostrando los mayores crecimientos y rendimientos con D2, con valores de SGR=0.65±0.09 g/día; FCA=3.76 y K=0.81±0.06. La supervivencia fue D1=51.4%, D2=50% y D3=77.8% sin diferir estadísticamente entre las diferentes dietas. Conclusiones. El cultivo de esta especie en estanques de agua dulce con suministro de alimento comercial para cobia es viable en términos de crecimiento y ganancia en peso.
RESUMO
OBJECTIVE The objective of this study was to investigate the association between food assistance program participation and overweight/obesity according to poverty level. METHODS A cross-sectional analysis of data from 46,217 non-pregnant and non-lactating women in Lima, Peru was conducted; these data were obtained from nationally representative surveys from the years 2003, 2004, 2006, and 2008-2010. The dependent variable was overweight/obesity, and the independent variable was food assistance program participation. Poisson regression was used to stratify the data by family socioeconomic level, area of residence (Lima versus the rest of the country; urban versus rural), and survey year (2003-2006 versus 2008-2010). The models were adjusted for age, education level, urbanization, and survey year. RESULTS Food assistance program participation was associated with an increased risk of overweight/obesity in women living in homes without poverty indicators [prevalence ratio (PR) = 1.29; 95% confidence interval (CI) 1.06;1.57]. When stratified by area of residence, similar associations were observed for women living in Lima and urban areas; no associations were found between food assistance program participation and overweight/obesity among women living outside of Lima or in rural areas, regardless of the poverty status. CONCLUSIONS Food assistance program participation was associated with overweight/obesity in non-poor women. Additional studies are required in countries facing both aspects of malnutrition. .
OBJETIVO Investigar associação entre participação no programa de assistência alimentar e sobrepeso/obesidade, segundo nível de pobreza. MÉTODOS Estudo transversal com dados sobre 46.217 mulheres não gestantes e não lactantes, de Lima, Peru, obtidos de pesquisas, com representatividade nacional, nos anos de 2003, 2004, 2006 e 2008-2010. A variável dependente foi o sobrepeso/obesidade e a independente foi a participação no programa de assistência alimentar. Utilizou-se regressão de Poisson; os modelos foram estratificados por nível socioeconômico familiar para todo o país, por área de residência (Lima versus o resto do país; urbano versus residência rural) e anos de estudo (2003-2006 versus 2008-2010). Os modelos foram ajustados por idade, nível acadêmico, urbanização e ano de estudo. RESULTADOS Participar do programa de assistência alimentar associou-se com risco aumentado de sobrepeso/obesidade para as mulheres que viviam em domicílios sem indicadores de pobreza (PR = 1,29; IC95% 1,06;1,57). Quando estratificados por área de residência, foram observadas associações similares para as mulheres que vivem em Lima e em áreas urbanas; não foram encontradas associações entre a participação no programa de assistência alimentar e sobrepeso/obesidade entre as mulheres que vivem fora de Lima ou em áreas rurais, independentemente de sua condição de pobreza. CONCLUSÕES Participar do programa de assistência alimentar associou-se com sobrepeso/obesidade para mulheres não pobres. Estudos adicionais serão necessários em países que enfrentam ambas as faces da má nutrição. .

The study objectives were to map the different stages of the nutrition transition for each departmentwithin Peru, and to determine the nutrition policy needs for each geographic areabased on their current stage in the nutrition transition. Results show that most of the countryis suffering from a double-burden of malnutrition, with high rates of stunting among childrenless than 5 years of age and high rates of overweight and obesity among women of reproductiveage. Currently, Peru has only country-wide nutrition policies, administered by the Ministryof Health, that are primarily focused on stunting prevention. This study argues for the need tohave decentralized nutrition policies that vary according to what type of malnutrition is beingexperienced in each geographic area.
Los objetivos de este estudio consistían en trazar un mapa por departamentos yetapas de la transición nutricional en el Perú y determinar las políticas nutricionalesnecesarias en las distintas zonas geográficas en función de sus etapas en la transición.Los resultados demuestran que la mayor parte del país está sufriendo la llamadadoble carga de la malnutrición, en la que coexisten tasas elevadas de desnutricióncrónica entre los menores de 5 años y tasas elevadas de sobrepeso y obesidad en lasmujeres en edad fecunda. En el Perú actual, las políticas nutricionales, gestionadaspor el Ministerio de Salud, están centralizadas y su prioridad es prevenir la detencióndel crecimiento. Este estudio aboga por la necesidad de contar con políticas nutricionalesdescentralizadas que varíen en función del tipo de malnutrición que se estépadeciendo en cada zona geográfica.
