Only half of the authors of overviews of exercise-related interventions use some strategy to manage overlapping primary studies-a metaresearch study.

OBJECTIVES: The conduct of systematic reviews (SRs) and overviews share several similarities. However, because the unit of analysis for overviews is the SRs, there are some unique challenges. One of the most critical issues to manage when conducting an overview is the overlap of data across the primary studies included in the SRs. This metaresearch study aimed to describe the frequency of strategies to manage the overlap in overviews of exercise-related interventions. STUDY DESIGN AND SETTING: A systematic search in MEDLINE (Ovid), Embase (Ovid), Cochrane Library, Epistemonikos, and other sources was conducted from inception to June 2022. We included overviews of SRs that considered primary studies and evaluated the effectiveness of exercise-related interventions for any health condition. The overviews were screened by two authors independently, and the extraction was performed by one author and checked by a second. We found 353 overviews published between 2005 and 2022 that met the inclusion criteria. RESULTS: One hundred and sixty-four overviews (46%) used at least one strategy to visualize, quantify, or resolve overlap, with a matrix (32/164; 20%), absolute frequency (34/164; 21%), and authors' algorithms (24/164; 15%) being the most used methods, respectively. From 2016 onwards, there has been a trend toward increasing the use of some strategies to manage overlap. Of the 108 overviews that used some strategy to resolve the overlap, ie, avoiding double or multiple counting of primary study data, 79 (73%) succeeded. In overviews where no strategies to manage overlap were reported (n = 189/353; 54%), 16 overview authors (8%) recognized this as a study limitation. CONCLUSION: Although there is a trend toward increasing its use, only half of the authors of the overviews of exercise-related interventions used a strategy to visualize, quantify, or resolve overlap in the primary studies' data. In the future, authors should report such strategies to communicate more valid results.

¿Cómo y Cuánto se Mueven los Adultos que sufrieron un Evento Coronario un Año después de haber entrado a un Programa de Rehabilitación Cardiaca? / How and How Much Do Adults Who Suffered a Coronary Event Move One Year After Entering a Cardiac Rehabilitation Program?

Introducción. Establecer un estilo de vida activo y saludable es uno de los objetivos más importantes y desafiantes de la rehabilitación cardíaca. Comprender el comportamiento de los patrones de actividad física (AF) en adultos que han sufrido un evento coronario y que han participado en un programa de Rehabilitación Cardíaca (RC) es necesario para evaluar su impacto y proponer estrategias oportunas en esta área. Objetivo. Evaluar el cumplimiento de la recomendación global de AF 1 año después de ingresar a un programa de RC para enfermedad arterial coronaria. Métodos. Se aplicó el Cuestionario Internacional de Actividad Física a adultos con enfermedad coronaria tratada a los 6 y 12 meses de su ingreso a un programa de Rehabilitación Cardíaca en 6 hospitales de Chile, entre mayo de 2019 y febrero de 2020 en el contexto del estudio aleatorizado. Se realizó un ensayo clínico multicéntrico de no inferioridad (Hybrid Cardiac Rehabilitation Trial, HYCARET). Resultados. 117 participantes (74 hombres, edad 59,34 ±9,52 años, 83,4±27,2% de adherencia a la RC) físicamente activos al final de un programa de RC fueron evaluados a los 6 y 12 meses desde el ingreso para determinar su adherencia a la AF. La tasa de seguimiento fue del 94,01% a los 6 meses (6m) y del 78,63% a los 12 meses (12m). El 90% de los participantes seguían físicamente activos a los 6 meses y el 92,39% seguían activos a los 12 meses después del evento coronario. Un 5,98% fueron clasificados como inactivos a los 6 m pero estaban físicamente activos al año. En contraste, sólo el 0,85% se volvió inactivo a los 6 meses y permaneció inactivo hasta 1 año, mientras que el 4,27% se reportó como activo a los 6 meses, pero terminó estando inactivo al año. La AF relacionada con las tareas del hogar es responsable del 40% y más del gasto calórico total de los adultos después de un evento coronario en todo momento. El gasto calórico relacionado con actividades recreativas y transporte disminuyó a los 6 y 12 meses, mientras que el gasto calórico asociado con el trabajo y las actividades domésticas aumentó a los 6 y 12 meses después de completar un programa de RC. Conclusión. Los adultos que completan un programa de RC continúan activos 6 y 12 meses después de un evento coronario. Sin embargo, las actividades que generan mayor gasto calórico varían con el tiempo. Este hallazgo resalta la importancia de fomentar la actividad física como parte del tiempo de ocio y recreación en los adultos, ya que se sabe que su beneficio es mayor.

Background. Establishing a healthy, active lifestyle is one of the most important and challenging goals of cardiac rehabilitation. Understanding the behavior of physical activity (PA) patterns in adults who have suffered a coronary event and who have participated in a Cardiac Rehabilitation (CR) program is necessary to evaluate its impact and propose timely strategies in this area. Objetive. To evaluate compliance with the global PA recommendation 1 year after entering a CR program for coronary artery disease. Methods. The International Physical Activity Questionnaire was applied to adults with coronary heart disease treated 6 and 12 months after admission to a Cardiac Rehabilitation program in 6 hospitals in Chile, between May 2019 and February 2020 in the context of the randomized study. A multicenter non-inferiority clinical trial (Hybrid Cardiac Rehabilitation Trial, HYCARET) was conducted. Results. 117 participants (74 men, age 59.34 ± 9.52 years, 83.4 ± 27.2% adherence to CR) physically active at the end of a CR program were evaluated at 6 and 12 months from entry. to determine their adherence to PA. The follow-up rate was 94.01% at 6 months (6m) and 78.63% at 12 months (12m). 90% of participants were still physically active at 6 months and 92.39% were still active at 12 months after the coronary event. 5.98% were classified as inactive at 6 m but were physically active at one year. In contrast, only 0.85% became inactive at 6 months and remained inactive for up to 1 year, while 4.27% reported themselves as active at 6 months but ended up being inactive at one year. Housework-related PA is responsible for 40% and more of adults' total caloric expenditure after a coronary event at all times. Caloric expenditure related to recreational activities and transportation decreased at 6 and 12 months, while caloric expenditure associated with work and home activities increased at 6 and 12 months after completing a CR program. Conclusion. Adults who complete a CR program remain active 6 and 12 months after a coronary event. However, the activities that generate the greatest caloric expenditure vary over time. This finding highlights the importance of promoting physical activity as part of leisure and recreation time in adults, since it is known that its benefit is greater.

Hybrid Cardiac Rehabilitation Program in a Low-Resource Setting: A Randomized Clinical Trial.

Importance: While effective, cardiovascular rehabilitation (CR) as traditionally delivered is not well implemented in lower-resource settings. Objective: To test the noninferiority of hybrid CR compared with traditional CR in terms of cardiovascular events. Design, Setting, and Participants: This pragmatic, multicenter, parallel arm, open-label randomized clinical trial (the Hybrid Cardiac Rehabilitation Trial [HYCARET]) with blinded outcome assessment was conducted at 6 referral centers in Chile. Adults aged 18 years or older who had a cardiovascular event or procedure, no contraindications to exercise, and access to a mobile telephone were eligible and recruited between April 1, 2019, and March 15, 2020, with follow-up until July 29, 2021. Interventions: Participants were randomized 1:1 in permuted blocks to the experimental arm, which received 10 center-based supervised exercise sessions plus counseling in 4 to 6 weeks and then were supported at home via telephone calls and text messages through weeks 8 to 12, or the control arm, which received the standard CR of 18 to 22 sessions with exercises and education in 8 to 12 weeks. Main Outcomes and Measures: The primary outcome was cardiovascular events or mortality. Secondary outcomes were quality of life, return to work, and lifestyle behaviors measured with validated questionnaires; muscle strength and functional capacity, measured through physical tests; and program adherence and exercise-related adverse events, assessed using checklists. Results: A total of 191 participants were included (mean [SD] age, 58.74 [9.80] years; 145 [75.92%] male); 93 were assigned to hybrid CR and 98 to standard CR. At 1 year, events had occurred in 5 unique participants in the hybrid CR group (5.38%) and 9 in the standard CR group (9.18%). In the intention-to-treat analysis, the hybrid CR group had 3.80% (95% CI, -11.13% to 3.52%) fewer cardiovascular events than the standard CR group, and relative risk was 0.59 (95% CI, 0.20-1.68) for the primary outcome. In the per-protocol analysis at different levels of adherence to the intervention, all 95% CIs crossed the noninferiority boundary (eg, 20% adherence: absolute risk difference, -0.35% [95% CI, -7.56% to 6.85%]; 80% adherence: absolute risk difference, 3.30% [95% CI, -3.70% to 10.31%]). No between-group differences were found for secondary outcomes except adherence to supervised CR sessions (79.14% [736 of 930 supervised sessions] in the hybrid CR group vs 61.46% [1201 of 1954 sessions] in the standard CR group). Conclusions and Relevance: The results suggest that a hybrid CR program is noninferior to standard center-based CR in a low-resource setting, primarily in terms of recurrent cardiovascular events and potentially in terms of intermediate outcomes. Hybrid CR may induce superior adherence to supervised exercise. Clinical factors and patient preferences should inform CR model allocation.

Assessment of activities and participation of people by rehabilitation-focused clinical registries: a systematic scoping review.

INTRODUCTION: Rehabilitation is considered a key intervention in health care. Clinical registries, defined as an organized system that uses observational methods to collect information to assess specific outcomes in a defined population, can contribute to assessing the impact of the rehabilitation intervention. This review aims to identify and describe rehabilitation-specific registry systems with an emphasis on identifying outcomes that enable the assessment of vital areas and activities of daily living. EVIDENCE ACQUISITION: A systematic scoping review was conducted. A systematic search was conducted up to August 2022 in MEDLINE/PubMed, Embase, Cochrane Library, Epistemonikos, and other search resources. Studies related to rehabilitation registries presented data on people with health problems that could limit their functioning were selected. The inclusion of studies/clinical registries was not limited by methodological design, year of publication, country, or language. The unit of analysis was rehabilitation registries. The measurement instruments used to assess the outcomes were explored to estimate the domain assessed from the vital areas related to functioning and disability as described by the International Classification of Functioning, Disability and Health (ICF). The vital areas were classified according to activities of daily living (ADLs). EVIDENCE SYNTHESIS: Seventy-one registries in rehabilitation were identified. The registries included a median of 3 (IQR 2-5) assessment instruments designed to assess the impact of different rehabilitation programs. In total, 137 different assessment scales or instruments were identified. Each rehabilitation registry assessed 6 (IQR 2-8) domains of the ICF, and 15.4% of registries assessed all domains. The most assessed domain was "Mobility" (89.7%), and the least assessed was "General Tasks and Demands" (25.6%). In addition, 92.3% of rehabilitation registries assessed basic ADLs, 76.9% advanced ADLs, and 71.8% instrumental ADLs. CONCLUSIONS: Although clinical registries do not claim to directly assess the impact of rehabilitation programs on people's functioning according to the ICF framework, it was identified that a low percentage of them assessed the nine vital areas through different outcome assessment instruments. However, most rehabilitation registries directly or indirectly assess some basic, instrumental, and advanced ADLs. The findings of this review highlight the need to improve the design of clinical registries focused on assessing the impact of rehabilitation programs to assess people in all areas of their lives.

Assessment of redundancy, methodological and reporting quality, and potential discrepancies of results of systematic reviews of early mobilisation of critically ill adults: a meta-research protocol.

INTRODUCTION: Several systematic reviews (SRs) have been conducted to determine the effectiveness of early mobilisation in critically ill adults with heterogeneous methodology and results. Redundancy in conducting SRs, unclear justification when leading new SRs or updating, and discordant results of SRs on the same research question may generate research waste that makes it difficult for clinicians to keep up to date with the best available evidence. This meta-research aims to assess the redundancy, methodological and reporting quality, and potential reasons for discordance in the results reported by SRs conducted to determine the effectiveness of early mobilisation in critically ill adult patients. METHODS AND ANALYSIS: A meta-research of early mobilisation SRs in critically ill adult patients will be conducted. A search of MEDLINE (Ovid), Embase (Ovid), CINAHL (EBSCOhost), Cochrane Library, Epistemonikos and other search resources will be conducted. Two independent reviewers will perform study selection, data extraction and quality appraisal. Discrepancies will be resolved by consensus or a third reviewer. The redundancy of SRs will be assessed by the degree of overlap of primary studies. In addition, the justification for conducting new SRs will be evaluated with the 'Evidence-Based Research' framework. The methodological quality of the SRs will be assessed with the A MeaSurement Tool to Assess systematic Reviews 2 tool, and the quality of the reports through compliance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. To assess the potential reasons for discordance in the results of the SRs considering divergence in results and their interpretation. ETHICS AND DISSEMINATION: As meta-research, this study does not involve the participation of people whose rights may be violated. However, this overview will be developed rigorously and systematically to achieve valid and reliable results. The findings of this meta-research study will be presented at conferences and published in a peer-reviewed journal related to rehabilitation, critical care or research methodology.

Evaluation of counselling materials for hybrid cardiac rehabilitation in a low-resource setting: Perceptions of patients and providers.

OBJECTIVE: This study evaluated the usefulness of a booklet as support material for counseling focused on self-efficacy and therapist interaction in the course of counseling in a hybrid CR program (i.e., supervised and unsupervised sessions) developed for low-resource settings. METHODS: Counseling material was developed by a multidisciplinary team, with patient input. Using multi-methods, first input from patients from six centers in Chile was sought through a telephone survey (cross-sectional). Second, input from physiotherapists delivering the intervention at all centres was solicited qualitatively through a focus group on Zoom. Content analysis was performed using a deductive-thematic approach. RESULTS: Seventy-one patients were included. All (100 %) participants responded that the materials were easy to understand, contained suggestions applicable to daily life, captured their attention and was useful for future questions. The booklet overall was rated 6.7 ± 0.6/7 %, and 98.2 % were satisfied with the counselling. Overall themes from the six deliverers related to the CR intervention (e.g., well manualized protocols for counselling), the deliverer (e.g., expertise to deliver) and patients (e.g., found information useful). CONCLUSION: The usefulness of the counseling together with the supporting booklet was established by patients and delivering professionals. PRACTICE IMPLICATIONS: Thus, with some final refinement, this resource can be disseminated for use by other Spanish CR programs.

Effectiveness of physical rehabilitation interventions in critically ill patients-A protocol for an overview of systematic reviews.

INTRODUCTION: Adult and pediatric patients admitted to intensive care units (ICUs) requiring invasive ventilatory support, sedation, and muscle blockade may present neuromusculoskeletal deterioration. Different physical rehabilitation interventions have been studied to evaluate their effectiveness in improving critically ill patients' outcomes. Given that many published systematic reviews (SRs) aims to determine the effectiveness of different types of physical rehabilitation interventions, it is necessary to group them systematically and assess the methodological quality of SRs to help clinicians make better evidence-based decisions. This overview of SRs (OoSRs) aims to map the existing evidence and to determine the effectiveness of physical rehabilitation interventions to improve neuromusculoskeletal function and other clinical outcomes in adult and pediatric critically ill patients. METHODS: An OoSRs of randomized and non-randomized clinical trials involving critically ill adult and pediatric patients receiving physical rehabilitation intervention will be conducted. A sensitive search of MEDLINE (Ovid), Embase (Ovid), CINAHL (EBSCOhost), Cochrane Library, Epistemonikos, and other search resources will be conducted. Two independent reviewers will conduct study selection, data extraction, and methodological quality assessment. Discrepancies will be resolved by consensus or a third reviewer. The degree of overlap of studies will be calculated using the corrected covered area. The methodological quality of the SRs will be measured using the AMSTAR-2 tool. The GRADE framework will report the certainty of evidence by selecting the "best" SR for each physical rehabilitation intervention and outcome. DISCUSSION: The findings of this overview are expected to determine the effectiveness and safety of physical rehabilitation interventions to improve neuromusculoskeletal function in adult and pediatric critically ill patients based on a wide selection of the best available evidence and to determine the knowledge gaps in this topic by mapping and assessing the methodological quality of published SRs.

Introducción: la decisión de suplementar la nutrición parenteral total (NPT) con emulsiones de los ácidos grasos (AG) omega-3 (Ω3) eicosapentaenoico (EPA) y docosahexaenoico (DHA) de origen marino se basa en los beneficios clínicos obtenidos en distintas situaciones médicas y quirúrgicas, entre los que destacan la reducción de la estancia hospitalaria, de los días de ventilación mecánica, de la incidencia de infecciones y de la mortalidad. Sin embargo, la evidencia en pacientes críticos aún es contradictoria. Objetivo: el objetivo de este ensayo clínico fue analizar el efecto de la suplementación con AG Ω3 EPA/DHA sobre los marcadores de pronóstico clínico: médicos, nutricionales y bioquímicos, en pacientes en estado crítico, en relación con el desenlace. Método: ensayo clínico, controlado, aleatorizado y unicéntrico en 64 pacientes adultos con condición crítica, de los cuales 47 pacientes se aleatorizaron para recibir NPT suplementada con AG Ω3 EPA/DHA a dosis de 0,1 g/kg/día (n = 23) o 0,2 g/kg/día (n = 24), comparados con un grupo de control histórico con NPT sin suplementación (n = 17). Se determinaron de manera basal y al final del soporte nutricional los marcadores de pronóstico clínico: médicos, nutricionales y bioquímicos. Resultados: los dos grupos con suplementación mostraron una reducción estadísticamente significativa de la mortalidad (p < 0,005); los marcadores de pronóstico clínico: SOFA, APACHE II, SAPS 3, NUTRIC, RTL y CRS, fueron consistentes en mostrar una mejoría significativa (p < 0,005) del pronóstico con las dosis de 0,1 y 0,2 g/kg/día de AG Ω3 EPA/DHA, respectivamente. Conclusión: la suplementación de la nutrición parenteral con ácidos grasos AG Ω3 EPA/DHA a dosis de 0,1 g y 0,2 g/kg/día mejora el pronóstico de la recuperación y la probabilidad de sobrevida en los pacientes críticos.

Introduction: the decision to supplement total parenteral nutrition (TPN) with emulsions of omega-3 (Ω3) eicosapentaenoic (EPA) and docosahexaenoic (DHA) fatty acids (FA) of marine origin is based on the clinical benefits obtained in different medical situations and surgical procedures, among which reductions in hospital stay, days of mechanical ventilation, incidence of infections and mortality stand out. However, the evidence in critically ill patients remains contradictory. Objective: the objective of this clinical trial was to analyze the effect of supplementation with EPA/DHA Ω3 FAs on clinical prognostic markers - medical, nutritional and biochemical - in critically ill patients, relating to outcome. Method: a clinical, controlled, randomized, single-center trial in 64 critically ill adult patients, of which 47 patients were randomized to receive TPN supplemented with EPA/DHA Ω3 FAs in doses of 0.1 g/kg/day (n = 23) and 0.2 g/kg/day (n = 24), compared with a historical control group with TPN without supplementation (n = 17). Clinical prognosis markers were determined at baseline and at the end of nutritional support (medical, nutritional and biochemical). Results: the two groups with supplementation showed a statistically significant reduction in mortality (p < 0.005); the clinical prognostic markers SOFA, APACHE II, SAPS 3, NUTRIC, RTL and CRS were consistent in showing a significant improvement (p < 0.005), of prognosis with doses of 0.1 and 0.2 g/kg/day of EPA/DHA Ω3 FAs, respectively. Conclusion: supplementation of parenteral nutrition with EPA/DHA Ω3 fatty acids at doses of 0.1 g and 0.2 g/kg/day improves recovery prognosis and the probability of survival in critically ill patients.

Seroprevalencia y factores de riesgo asociados a toxoplasmosis gestacional en el Nororiente Colombiano / Seroprevalence and risk factors for congenital toxoplasmosis in the northeastern region of Colombia / Soroprevalência e fatores de risco associados à toxoplasmose gestacional no nordeste da Colômbia

Introduction: Toxoplasmosis is a zoonosis prevalent in one-third of the world's population, adversely affecting maternal-fetal health by causing varying degrees of damage to the fetus. Objective: To assess the seroprevalence of Toxoplasma gondii IgG and IgM antibodies and associated risk factors in first-trimester pregnant women in Cúcuta, Colombia, in 2018. Materials and Methods: Cross-sectional and correlational study in 111 women who voluntarily participated. Specific IgM and IgG antibodies were detected by luminescence immunoassay (LIA). Results: Total seropositivity for IgM and IgG was 19.8% and 35.1%, respectively, 11.7% was for IgM only, and 53.2% corresponded to the overall seronegativity rate for T. gondii. Risk factors (CI = 95%) such as undercooked meat consumption (54.1% of cases, OR = 1.8, p = 0.120), tap water consumption (48.6%, OR = 1.4, p = 0.421), and goat or cow raw milk consumption (39.6%, OR = 0.78, p = 0.553) were identified; in addition, living with cats (23.4%) was identified as a risk factor significantly associated with parasite seropositivity (OR = 2.8, p = 0.025). Discussion and Conclusions: Our findings showed a possible risk of primary infection in more than half of the pregnant population, given the seronegativity against the parasite. A considerable frequency of suspected cases of very recent infection was also found. In addition to being associated with a previously recognized risk factor, this fact suggests the presence of other dietary risks that should be addressed through prevention strategies during prenatal care and the need to strengthen event surveillance.

Introdução: A toxoplasmose é uma zoonose prevalente em um terço da população mundial, que afeta negativamente a saúde materno-fetal, causando diversos graus de danos ao feto. Objetivo: Propôs-se avaliar o estado sorológico IgG e IgM anti - Toxoplasma gondii e fatores de risco relacionados, em gestantes no primeiro trimestre em Cúcuta, Colômbia, no ano de 2018. Material e Métodos: Estudo transversal e correlacional em Participaram 111 mulheres voluntariamente, que foram testadas para IgM e IgG específicos pelo imunoensaio LIA. Resultados: 19,8% e 35,1% do total de soropositividade foram encontrados para IgM e IgG, respectivamente, 11,7% foi apenas para IgM e 53,2% corresponde à frequência de soronegatividade geral para T.gondii; Foram identificados fatores de risco (IC=95%) , como consumo de carne mal cozida (54,1% dos casos, OR= 1,8, p=0,120 ), água da torneira (48,6%, OR=1,4, p=0,421), cru leite de cabra ou vaca (39,6%, OR=0,78, p=0,553 ), além de conviver com gatos (23,4%), sendo este último significativamente associado à soropositividade ao parasita ( OR=2,8 , p =0,025 ). Discussão e conclusões: Nossos achados revelam um possível risco de infecção primária em mais da metade da população gestante dada a sua soronegatividade contra o parasita, mas também uma frequência considerável de casos com suspeita de infecção muito recente, que, além de estar associada a um fator de risco previamente reconhecido , sugere outros aspectos de risco em torno da alimentação que devem ser impactados por meio de estratégias de prevenção durante o pré-natal, sugerindo a necessidade de fortalecer a vigilância em torno do evento.

Evaluación del soporte nutricional intensivo en pacientes con neumonía grave por COVID-19

RESUMEN Introducción: En los pacientes críticos con COVID-19 ocurren una serie de alteraciones metabólicas, las cuales afectan directamente el estado nutricional del paciente. Para mejorar la sobrevida de los pacientes con COVID-19, se hace relevante el tratamiento nutricional oportuno, idealmente dentro de las primeras 24-48 horas de la admisión a la UCI. El objetivo de este estudio fue reportar la evolución, desde el ingreso hasta el egreso, del balance nitrogenado, diversos parámetros bioquímicos y el estado nutricional de los pacientes con neumonía por COVID-19. Método: Estudio observacional retrospectivo de temporalidad longitudinal, se realizó en la UCI del Hospital Las Higueras de Talcahuano, Chile. Se incluyeron a 33 pacientes al ingreso y al egreso de la UCI. Resultados: Se reportó un incremento significativo del balance nitrogenado al egreso de los pacientes de UCI, sin embargo, no se registraron cambios en la media de talla, peso, IMC, prevalencia de desnutrición durante la estancia en la UCI. La prevalencia de desnutrición moderada y severa fue de un 14,0%, valor inferior al 45,0% informado en pacientes con COVID-19. Conclusión: En este estudio se reportó que la implementación del protocolo y la terapia nutricionales durante la pandemia de COVID-19 se asoció a un aumento del balance nitrogenado y un mejor control glicémico en los pacientes que egresan de la UCI por neumonía de COVID-19.

ABSTRACT Introduction: In critically ill patients with COVID-19, a series of metabolic alterations occur, which directly affect the patient's nutritional status. To improve the survival of patients with COVID-19, timely nutritional treatment is relevant, ideally within the first 24-48 hours of admission to the ICU. The objective of this study was to report the evolution, from admission to discharge, of the nitrogen balance, various biochemical parameters and the nutritional status of patients with COVID-19 pneumonia. Method: We conducted a retrospective observational study in the ICU of Las Higueras Hospital in Talcahuano, Chile. Thirty-three patients were included at admission and discharge from the ICU. Results: A significant increase in nitrogen balance was reported at ICU patient discharge, however, no changes were recorded in mean height, weight, BMI, or prevalence of malnutrition during ICU stay. The prevalence of moderate and severe malnutrition was 14.0%, a value lower than the 45.0% reported in patients with COVID-19. Discussion: In this study we reported that the implementation of the nutritional protocol and therapy during the COVID-19 pandemic was associated with an increase in nitrogen balance and better glycemic control in patients discharged from the ICU due to COVID-19 pneumonia.

A hybrid exercise-based cardiac rehabilitation program is an effective strategy to improve muscle strength and functional exercise capacity in adults and older people with coronary artery disease.

Coronary heart disease is the most common cause of death worldwide. Standard cardiac rehabilitation (face-to-face sessions) has shown benefits in increasing muscle strength and functional exercise capacity in adults and older people. However, it is unknown whether hybrid cardiac rehabilitation (a first face-to-face phase + a second remote monitoring phase) will have similar benefits in adults versus older subjects. The aim of this study was to compare the effects of a hybrid exercise-based cardiac rehabilitation program on muscle strength and functional exercise capacity in "adult" versus "older" people with coronary artery disease. We hypothesized that a hybrid exercise-based cardiac rehabilitation program would improve muscle strength and functional exercise capacity, but the impact would be smaller in the older group than the adult individuals. This study is part of a larger project (The Hybrid Cardiac Rehabilitation Trial-HYCARET). We subjected 22 adult (<60 y) females and males (ADULT; n = 5/17 (f/m); 52 ± 5 y; 28.9 ± 3.4 kg·m-2) and 20 older (≥60 y) females and males (OLDER; n = 6/14 (f/m); 66 ± 4 y; 27.4 ± 3.9 kg·m-2) with coronary artery disease to 12 weeks of hybrid exercise-based cardiac rehabilitation program. Prior to and after 12 weeks of a hybrid exercise-based cardiac rehabilitation program, grip strength (handgrip), leg strength (chair stand test), and functional exercise capacity (6-minute walk test, 6MWT) were assessed. The hybrid exercise-based cardiac rehabilitation program resulted in a 9.4 ± 14.6% and a 6.2 ± 12.1% grip strength increase, a 14.4 ± 39.4% and a 28.9 ± 48.1% legs strength increase, and a 14.6 ± 26.4% and a 6.8 ± 14.0% functional exercise capacity improvement in ADULT and OLDER, respectively (p < 0.05) with no differences between groups. In conclusion, a hybrid exercise-based cardiac rehabilitation program could increase muscle strength and improve functional exercise capacity in adults and older people with coronary artery disease. More future studies comparing effectiveness among these age groups are needed to strengthen this conclusion.

Enfermedad por inyección de rellenos sintéticos permanentes (EIRSP). Recomendaciones del grupo de expertos del Capítulo de Biomateriales de la FILACP / Disease caused by permanent synthetic fillers FILACP Biomaterials Committee expert group recomendations

La enfermedad por rellenos sintéticos permanentes (EIRSP) representa un verdadero problema de salud pública sobre todo en América Latina, afectando a millones de personas, predominantemente mujeres de mediana edad de estrato económico medio-bajo. Actualmente no existe una conducta terapéutica consensuada, razón que motivó al Comité de Biomateriales de la FILACP 2020-2022 a crear un grupo de 9 expertos quienes se plantearon los siguientes objetivos: 1.- Resaltar la importancia de la enfermedad, 2.- Clasificar sus estadios clínicos, 3.- Proponer un protocolo integral de diagnóstico y tratamiento, 4.- Proponer una estrategia terapéutica multidisciplinaria y 5.- Promover campañas de prevención.El relleno sintético más utilizado con fines estéticos ha sido la silicona inyectada en cara, glúteos, mamas, miembros inferiores, manos y genitales, con alto potencial de migración. Otras substancias son el metacrilato, aceites minerales, parafina y la combinación de ellas. Ninguno de estos productos es de grado médico ni biocompatible. Al ser inyectados van a producir diversas reacciones locales y sistémicas desencadenadas por reacción de hipersensibilidad tipo IV, conduciendo al desarrollo de una enfermedad autoinmune de tejido conectivo.Se propone una clasificación basada en 6 estadios clínicos o grados. 1: Sin signos ni síntomas. 2: Cambios de coloración. 3: Inflamación, induraciones, cambios de textura y dolor. 4: Extrusión del producto con o sin infección. 5: Migración. 6: Complicaciones locales o sistémicas graves.Se establecen las pautas diagnósticas basadas en la historia clínica, exámenes de laboratorio, inmunológicos y radiológicos. Para este último, la resonancia magnética es la técnica de elección y en algunos casos, con excepción de glúteos y mamas, el ultrasonido es de gran utilidad. (AU)

Disease caused by permanent synthetic fillers (EIRSP acronym in Spanish) represents a real public health problem, especially in Latin America, affecting millions of people, predominantly middle-aged women from a medium-low economic stratum. Currently, there is no consensual therapeutic behavior, the reason that motivated the FILACP Biomaterials Committee 2020-2022 to create a group of 9 experts, who set the following objectives: 1.- Highlight the importance of the disease, 2.- Classify the clinical stages, 3.- Propose a comprehensive diagnosis and treatment protocol, 4.- Propose a multidisciplinary therapeutic strategy and 5.- Promote prevention campaigns.The most widely used synthetic filler for aesthetic purposes has been silicone injected into the face, buttocks, breasts, lower limbs, hands and genitals, with a high potential for migration. Other substances are methacrylate, mineral oils, paraffin, and a combination. None of these products have a medical grade or are biocompatible. When injected, they will produce various local and systemic reactions triggered by type IV hypersensitivity reactions, leading to the development of autoimmune connective tissue disease.A classification based on 6 clinical stages or grades is proposed. 1: No signs or symptoms. 2: Color changes. 3: Inflammation, indurations, texture changes, and pain. 4: Extrusion of the product with or without infection. 5: Migration. 6: Severe local or systemic complications.Diagnostic guidelines are established based on clinical history, laboratory, immunological and radiological tests. For the latter, magnetic resonance imaging is the technique of choice, and in some cases, except for the buttocks and breasts, ultrasound is beneficial. (AU)

Personal and household PM2.5 and black carbon exposure measures and respiratory symptoms in 8 low- and middle-income countries.

BACKGROUND: Household air pollution (HAP) from cooking with solid fuels has been associated with adverse respiratory effects, but most studies use surveys of fuel use to define HAP exposure, rather than on actual air pollution exposure measurements. OBJECTIVE: To examine associations between household and personal fine particulate matter (PM2.5) and black carbon (BC) measures and respiratory symptoms. METHODS: As part of the Prospective Urban and Rural Epidemiology Air Pollution study, we analyzed 48-h household and personal PM2.5 and BC measurements for 870 individuals using different cooking fuels from 62 communities in 8 countries (Bangladesh, Chile, China, Colombia, India, Pakistan, Tanzania, and Zimbabwe). Self-reported respiratory symptoms were collected after monitoring. Associations between PM2.5 and BC exposures and respiratory symptoms were examined using logistic regression models, controlling for individual, household, and community covariates. RESULTS: The median (interquartile range) of household and personal PM2.5 was 73.5 (119.1) and 65.3 (91.5) µg/m3, and for household and personal BC was 3.4 (8.3) and 2.5 (4.9) x10-5 m-1, respectively. We observed associations between household PM2.5 and wheeze (OR: 1.25; 95%CI: 1.07, 1.46), cough (OR: 1.22; 95%CI: 1.06, 1.39), and sputum (OR: 1.26; 95%CI: 1.10, 1.44), as well as exposure to household BC and wheeze (OR: 1.20; 95%CI: 1.03, 1.39) and sputum (OR: 1.20; 95%CI: 1.05, 1.36), per IQR increase. We observed associations between personal PM2.5 and wheeze (OR: 1.23; 95%CI: 1.00, 1.50) and sputum (OR: 1.19; 95%CI: 1.00, 1.41). For household PM2.5 and BC, associations were generally stronger for females compared to males. Models using an indicator variable of solid versus clean fuels resulted in larger OR estimates with less precision. CONCLUSIONS: We used measurements of household and personal air pollution for individuals using different cooking fuels and documented strong associations with respiratory symptoms.

Two-Minute Step Test as a Complement to Six-Minute Walk Test in Subjects With Treated Coronary Artery Disease.

The 2-Minute Step Test (2MST) has been presented as an alternative to the 6-Minute Walk Test (6MWT) based on the association between the two tests in older adults; however, some authors propose that it should not be a substitute but rather a complement to the latter in the fitness evaluation. Specifically, in coronary disease, despite the potential and clinical utility of 2MST, the relationship of both tests in this population is unknown. This study aimed to determine the relationship between 6MWT and 2MST and to explore the relationship of biodemographic factors for both tests in subjects with treated coronary artery disease. For this, the 6MWT and the 2MST were applied to patients with coronary artery disease treated in 6 hospitals in Chile between May 2019 and February 2020. Additionally, lower limb strength was assessed by a chair-stand test, grip strength was assessed by a dynamometer, and physical measurements were applied. In total, 163 participants underwent both tests (average age = 58.7 ± 9.8 years; 73.6% men; 64.4% revascularized by angioplasty; 28.2% revascularized by surgery, and 7.4% treated by drugs or thrombolysis). Heart rate was higher at the end of the 6MWT, while the perception of effort was greater at the end of the 2MST. There was a weak positive correlation between the 6MWT and the 2MST in subjects with treated coronary disease (r = 0.28, p = 0.0003). While age (r = -0.27), weight (r = 0.25), height (r = 0.49), and strength of both lower limbs (r = 0.41) and grip strength (r = 0.53) correlated weakly or moderately to the covered distance in 6MWT, the number of steps by the 2MST correlated only weakly to height (r = 0.23), lower limb strength (r = 0.34), and grip strength (r = 0.34). Age, weight, height, lower limb strength, and grip strength would explain better the meters walked in the 6MWT than the steps achieved in the 2MST. With these findings, we can conclude that, in patients with treated coronary artery disease, it does not seem advisable to replace 6MWT with 2MST when it is possible to do so. Additionally, the 2MST may provide additional information in the fitness evaluation. However, the usefulness of 2MST in this population needs to be further studied.

Measuring and predicting personal and household Black Carbon levels from 88 communities in eight countries.

Black Carbon (BC) is an important component of household air pollution (HAP) in low- and middle- income countries (LMICs), but levels and drivers of exposure are poorly understood. As part of the Prospective Urban and Rural Epidemiological (PURE) study, we analyzed 48-hour BC measurements for 1187 individual and 2242 household samples from 88 communities in 8 LMICs (Bangladesh, Chile, China, Colombia, India, Pakistan, Tanzania, and Zimbabwe). Light absorbance (10-5 m-1) of collected PM2.5 filters, a proxy for BC concentrations, was calculated via an image-based reflectance method. Surveys of household/personal characteristics and behaviors were collected after monitoring. The geometric mean (GM) of personal and household BC measures was 2.4 (3.3) and 3.5 (3.9)·10-5 m-1, respectively. The correlation between BC and PM2.5 was r = 0.76 for personal and r = 0.82 for household measures. A gradient of increasing BC concentrations was observed for cooking fuels: BC increased 53% (95%CI: 30, 79) for coal, 142% (95%CI: 117, 169) for wood, and 190% (95%CI: 149, 238) for other biomass, compared to gas. Each hour of cooking was associated with an increase in household (5%, 95%CI: 3, 7) and personal (5%, 95%CI: 2, 8) BC; having a window in the kitchen was associated with a decrease in household (-38%, 95%CI: -45, -30) and personal (-31%, 95%CI: -44, -15) BC; and cooking on a mud stove, compared to a clean stove, was associated with an increase in household (125%, 95%CI: 96, 160) and personal (117%, 95%CI: 71, 117) BC. Male participants only had slightly lower personal BC (-0.6%, 95%CI: -1, 0.0) compared to females. In multivariate models, we were able to explain 46-60% of household BC variation and 33-54% of personal BC variation. These data and models provide new information on exposure to BC in LMICs, which can be incorporated into future exposure assessments, health research, and policy surrounding HAP and BC.

Multinational prediction of household and personal exposure to fine particulate matter (PM2.5) in the PURE cohort study.

INTRODUCTION: Use of polluting cooking fuels generates household air pollution (HAP) containing health-damaging levels of fine particulate matter (PM2.5). Many global epidemiological studies rely on categorical HAP exposure indicators, which are poor surrogates of measured PM2.5 levels. To quantitatively characterize HAP levels on a large scale, a multinational measurement campaign was leveraged to develop household and personal PM2.5 exposure models. METHODS: The Prospective Urban and Rural Epidemiology (PURE)-AIR study included 48-hour monitoring of PM2.5 kitchen concentrations (n = 2,365) and male and/or female PM2.5 exposure monitoring (n = 910) in a subset of households in Bangladesh, Chile, China, Colombia, India, Pakistan, Tanzania and Zimbabwe. PURE-AIR measurements were combined with survey data on cooking environment characteristics in hierarchical Bayesian log-linear regression models. Model performance was evaluated using leave-one-out cross validation. Predictive models were applied to survey data from the larger PURE cohort (22,480 households; 33,554 individuals) to quantitatively estimate PM2.5 exposures. RESULTS: The final models explained half (R2 = 54%) of the variation in kitchen PM2.5 measurements (root mean square error (RMSE) (log scale):2.22) and personal measurements (R2 = 48%; RMSE (log scale):2.08). Primary cooking fuel type, heating fuel type, country and season were highly predictive of PM2.5 kitchen concentrations. Average national PM2.5 kitchen concentrations varied nearly 3-fold among households primarily cooking with gas (20 µg/m3 (Chile); 55 µg/m3 (China)) and 12-fold among households primarily cooking with wood (36 µg/m3 (Chile)); 427 µg/m3 (Pakistan)). Average PM2.5 kitchen concentration, heating fuel type, season and secondhand smoke exposure were significant predictors of personal exposures. Modeled average PM2.5 female exposures were lower than male exposures in upper-middle/high-income countries (India, China, Colombia, Chile). CONCLUSION: Using survey data to estimate PM2.5 exposures on a multinational scale can cost-effectively scale up quantitative HAP measurements for disease burden assessments. The modeled PM2.5 exposures can be used in future epidemiological studies and inform policies targeting HAP reduction.

Impact of Outdoor Gyms on Adults' Participation in Physical Activity: A Natural Experiment in Chile.

BACKGROUND: Although low levels of physical activity have slightly decreased globally, the need to reverse the physical inactivity remains urgent. One approach has been the installation of outdoor gyms (OGs). METHOD: A natural experiment arose from the installation of OGs in different neighborhoods of the city of Temuco, Chile. Baseline measurements were collected between 2006 and 2017 in a cohort of adults participating in the Prospective Urban & Rural Epidemiology study. Physical activity was assessed with the short version of the International Physical Activity Questionnaire, and time-varying covariates was assessed every 3 years. The multistage hierarchical, nested sampling process and the follow-up assessments led to data correlated at different levels, thus the authors analyzed the data using a logistic multilevel model. RESULT: 2463 urban adults from 16 neighborhoods, with an average age of 51.7 (9.8) years (67% female), were included. Having an adequate number of OGs improved the odds of complying with the World Health Organization's recommendations (adjusted odds ratio = 4.64, 3.95-5.45). In addition, being male (odds ratio = 1.53, 1.32-1.77) and under the age of 60 years (odds ratio = 0.83, 0.71-0.97) were associated with being physically active. CONCLUSION: The presence of more OGs can have a positive impact on physical activity recommendations.
