Effects of school closure on lifestyle behaviours and health outcomes in children during the COVID-19 pandemic in Chile: A time-matched analysis.

BACKGROUND: The COVID-19 pandemic led to school closures, potentially impairing children's behaviours and health. We aimed to explore the effects of school closure on lifestyle behaviours (dietary habits, physical activity) and health outcomes (adiposity, fitness, self-esteem, self-concept) in children. METHODS: We measured 247 children before school closure (October-November 2019) and after school reopening (October-November 2021) (COVID-19 group). To distinguish the changes due to school closure from changes due to growth, we included 655 age-matched children with cross-sectional measurements in October-November 2019 (control group). The response of this group (i.e., differences between children with 2 years of difference) was considered the expected response to growth. Two-way ANOVA was used to test age-by-group interactions, indicating an effect of school closure. RESULTS: In 7-to-9-year-old children, the COVID-19 group had larger-than-expected decreases in physical activity (by 0.4 points), resulting in higher physical inactivity prevalence (by 19 percent points) at 9 years. This was accompanied by larger-than-expected increases in fat percentage (by 6.1 percent point). In 8-to-10-year-old children, the COVID-19 group had higher physical inactivity prevalence at 10 years (by 20 percent points). This was accompanied by larger-than-expected increases in fat percentage (by 8.3 percent points), z-score BMI (by 0.90 units), and waist circumference (by 6.1 cm). In 9-to-11-year-old children, the COVID-19 group had larger-than-expected decreases in physical activity (by 0.3 points) and increases in self-concept (by 0.2 points). The response in dietary habits, fitness, or self-esteem was not different between groups. CONCLUSION: Overall, school closure negatively impacted physical activity and adiposity, particularly in the youngest children.

Lecciones y desafíos del uso de los grupos relacionados por el diagnóstico en Chile / Using diagnosis-related groups in Chile: lessons and challenges / Lições e desafios do uso de grupos de diagnósticos relacionados no Chile

[RESUMEN].Objetivo. Analizar la implementación de los grupos relacionados por el diagnóstico (GRD) en Chile con miras a optimizar la distribución de los recursos públicos. Método. Se utilizó un análisis narrativo cronológico de los principales hitos, complementado por simulaciones de aplicación de los GRD mediante competencia emulada y análisis de conglomerados para fines evaluativos. Resultados. En el año 2001 se introdujeron los GRD en Chile, en un contexto académico. El Fondo Nacional de Salud (FONASA) comenzó a utilizarlos en el sector privado y, con un piloto, en el sector público en el 2015. Tras casi dos décadas de avances, en el 2020 se instaló el programa GRD como mecanismo de pago para los hospitales públicos desde el FONASA. Sin embargo, la pandemia de COVID-19 enlenteció su desarrollo. En el 2022 se retomó la aplicación y, tras evaluar el programa, se evidenció que los conglomerados de hospitales predefinidos para el pago diferenciado por GRD no lograron diferenciar grupos homogéneos. En el 2023 se reformó el programa y se aumentaron los recursos financieros, se definió un solo conglomerado y una tasa base, y se reconoció una mayor complejidad hospitalaria que la de años previos. Además, se agregaron tres hospitales al programa, con un total de 68. Conclusiones. La experiencia muestra que es posible dar continuidad a una política pública de financiamiento de la salud para lograr una mayor eficiencia y equidad en el sistema de salud, sobre la base de la existencia de instituciones robustas que persistan en su desarrollo y mejoramiento continuo.

[ABSTRACT]. Objective. Analyze the implementation of diagnosis-related groups (DRGs) in Chile with a view to optimizing the distribution of public resources. Methods. A chronological narrative analysis of the main milestones was complemented by simulated application of DRGs through emulated competition and cluster analysis for evaluative purposes. Results. In 2001, DRGs were introduced in Chile in an academic context. The National Health Fund (FONASA) began using DRGs in the private sector. A public sector pilot was launched in 2015. After nearly two decades of progress, in 2020 FONASA established the DRG program as a payment mechanism for public hospitals. However, the COVID-19 pandemic slowed its development. In 2022, implementation was resumed. After evaluating the program, it was evident that the hospital clusters that had been predefined for differentiated payment did not successfully differentiate homogeneous groups. In 2023, the program was reformed, financing was increased, a single cluster and base rate were defined, and greater hospital complexity was recognized, compared to previous years. Three hospitals were added to the program, for a total of 68. Conclusions. This experience shows that it is possible to sustain a public health financing policy that achieves greater efficiency and equity in the health system, based on the existence of robust institutions that continuously develop and improve.

[Dying during the pandemic: Experiences of relatives of patients who died during the COVID-19 pandemic in Chile]. / Morir en pandemia: Experiencias de familiares de pacientes fallecidos durante la pandemia COVID-19 en Chile.

INTRODUCTION: The COVID-19 pandemic marked a milestone in the history of medicine worldwide. Together with the humanitarian drama it represented, the problems that arose are promoting lines of research in multiple fields. One of these fields is the aspects related to medical communication and end-of-life care. This paper reports the experiences and perceptions of relatives of patients who died during the pandemic with a psychospiritual support intervention in a public hospital in the Metropolitan Region, Chile, called "farewell". METHODS: A qualitative study was conducted with a phenomenological approach based on in-depth interviews. From this, categories were derived that allowed a systematization of the observation of the experiences. RESULTS: Among the results, the impact of the circumstances and the communication provided by the medical team on grief should be highlighted. The use of the word "farewell" emerges as a useful, albeit ambiguous, communicative tool when it comes to adequately framing an end-of-life process. CONCLUSIONS: It is argued that the end of life is an area that requires physical and psychospiritual spaces, and adequate training at all levels to do justice to a highly relevant moment in the care of people.

[Association between pain and depression in chilean older adults. Reality that requires an immediate approach]. / Asociación entre dolor y depresión en adultos mayores chilenos. Realidad que requiere abordaje inmediato.

ABASTRACT Background: To study the association between pain and depression, its characteristics and related factors in chilean older adults. METHODS: Cross-sectional analytical study of the National Survey of Dependence in Chilean older adults 2009, with a sample of 4766 people aged 60 years and older. Pain was described using a Likert scale from "no pain" to "very much pain". Depression was measured using the GDS-15 scale. Adjusted logistic regression analyses were performed to identify the association between pain and depression. RESULTS: 70% of the sample reported pain, 21.6% of high intensity. The screening was positive for depression in 23% of the sample, and 5% suspected severe depression. Both conditions were more frequent in women, subjects with low levels of schooling and rural residence. There was an association between pain and depression OR 3.46. The greater the intensity of pain, the greater the association OR 5.2 (95% CI 4.1-6.7) for depressive symptoms and OR 13.9 for suspected severe depression (95% CI 8.1-23.9). CONCLUSION: The association between pain and depression is high and is related to pain intensity, being higher in people with less education and physical dependency. The high frequency of both conditions in Chilean elderly people and their serious consequences make it an urgent public health problem, aggravated as a consequence of the prolonged isolation due to the COVID-19 pandemic.

[Perceptions and experiences of users who received outpatient COVID-19 care in Santiago, Chile]. / Percepciones y experiencias de usuarios que recibieron cuidados ambulatorios de COVID-19 en Santiago de Chile.

AIM: To explore the perceptions and experiences of COVID-19 patients who received outpatient treatment in public health services in the Metropolitan Region of Chile. METHODS: An exploratory rapid qualitative study was conducted. Individual, telephonic and semi-structured interviews were conducted with patients who received a COVID-19 diagnosis confirmed by a PCR test and who had outpatient treatment for the disease. A thematic analysis was performed. RESULTS: Nine interviews were conducted (six female and three male participants). The main emerging themes were: life before COVID-19, living with the disease at home, recovery process, and Ineffective sanitary measures. Most of the participants highlighted the lack of information about their health and the uncertainty about COVID-19 as the cause of fear for their wellbeing. They also felt guilty for putting at risk others due to their COVID-19-positive status. CONCLUSION: The experiences of patients show the need to strengthen communication and information strategies for patients who receive outpatient care during the pandemic. This is key to reducing misinformation, fear and uncertainty about the progression of the disease and the potential recovery. Consequently, this could impact clinical outcomes and patient satisfaction.

[Evaluation of the state and implementation of the Hospital Clinical Forensic Units in Chile]. / Evaluación del estado e implementación de las Unidades Clínico Forense Hospitalarias en Chile.

BACKGROUND: Sexual violence has a several negative impact on women's health. Thus, the health system is a gateway for the multisector response to victims. In 2018, the Clinical Forensic Hospital Units (UCFH) in Chile were launched for this purpose. OBJECTIVE: To evaluate the state of implementation of the UCFH in the health services (HS) in Chile. METHOD: This is a quantitative descriptive, cross-sectional study. A survey was designed and applied through the Google Forms platform to the managers of the care and prevention network for victims of sexual violence (VSV) of each SS. The contact of each manager was requested by each HS in three ways: transparency law, lobby law, and telephone. Each HS was classified according to the existence or not of UCFH and for each unit the availability of resources was evaluated according to the recommendations of the Technical Standard of Attention to VSV of the Ministry of Health. Also, the functioning of each unit during the pandemic was evaluated. RESULTS: Twenty-four of the 29 HSs responded, of which 12 reported having UCFH. Of the 12 units, 50% had complete infrastructure, 58.3% had complete instruments, none had full human resources, 50% had partial HR, 50% had sampling complete, and 58. 3% had full health benefits. The function during the pandemic was affected in 25% of the units. CONCLUSION: Challenges persist in the implementation of the UCFH, with special limitations in the availability of human resources.

Sociodemographic Factors Related to Perceived Physical Activity on Chilean Adults after COVID-19 Pandemic.

The current study aimed to examine the relationship between sociodemographic variables (i.e., sex, age, marital status, educational level, socioeconomic status, and working mode) and physical activity levels declared by Chilean adults. The sample comprised 483 Chilean adults, 159 men (32.9%) and 324 women (67.1%) aged from 18 to 69 years old (36.5 ± 12.0). The participants completed an ad hoc sociodemographic online survey between December 2022 and March 2023 that included questions about characteristics of participants such as sex, age, educational level, household income, marital status, and working mode. Vigorous, moderate, and walking activities were measured using the International Physical Activity Questionnaire-Short Form (IPAQ-SF), a self-administered questionnaire. Men declared significantly higher vigorous and moderated physical activity than women. People aged 18 to 25, single or unmarried, and with the lowest household income, showed significantly higher scores in vigorous physical activity than those aged 26 to 45, cohabiting with a partner or married, and middle household income, respectively. Regarding working mode, people working at their job site said walking more than people not working, working in a hybrid mode, and working online. Our findings suggest that promoting strategies that increase physical activity during the pandemic is necessary to avoid health problems.

Enfermedad de Parkinson: tasa de mortalidad como causa básica en el periodo 2016-2023 en Chile / Parkinson's disease: mortality rate as a basic cause in the period 2016-2023 in Chile

INTRODUCTION: Parkinson's disease (PD) is a progressive neurodegenerative disease that primarily affects movement. The objective is to describe the mortality rate (MT) due to Parkinson's Disease in the period 2016 - 2023 in Chile. MATERIALS AND METHODS: Descriptive, observational and cross-sectional study. A descriptive analysis was carried out on TM due to PD as the underlying cause in patients from 45 years of age, according to sex, age group, regional distribution, place of death and month of death. Data were collected from the Department of Statistics and Health Information and the National Institute of Statistics, and were processed using Microsoft Office Excel. RESULTS: 5,785 deaths were studied, determining a MT of the period of 11.58 deaths per 100,000 inhabitants, with a maximum in 2023. A predominance is observed in men, over 80 years of age, residents in the Los Lagos region. DISCUSSION: A decrease in mortality from PD is observed during the years of the SARS-COV-2 pandemic, possibly associated with the fact that those patients suffering from PD could have died from respiratory causes. Men present higher rates, associated with biological differences and environmental exposure, as well as agricultural regions such as Los Lagos. There is a seasonal increase in winter due to climatic conditions that increase comorbidities. CONCLUSION: This study provides valuable information on PE mortality in Chile and highlights areas that could benefit from specific interventions, being essential to improve health care and policies in Chile.

INTRODUCCIÓN: La enfermedad de Parkinson (EP) es una enfermedad neurodegenerativa progresiva que afecta principalmente al movimiento. Se plantea como objetivo describir la tasa de mortalidad (TM) por Enfermedad de Parkinson en el periodo 2016 - 2023 en Chile. MATERIALES Y MÉTODOS: Estudio descriptivo, observacional y transversal. Se realizó un análisis descriptivo sobre la TM por EP como causa básica en pacientes desde 45 años, según sexo, grupo etario, distribución regional, lugar y mes del deceso. Los datos fueron recolectados desde el Departamento de Estadísticas e Información de Salud y el Instituto Nacional de Estadísticas, y se procesaron mediante Microsoft Office Excel. RESULTADOS: Se estudiaron 5.785 defunciones, determinando una TM del periodo de 11.58 defunciones por cada 100.000 habitantes, con un máximo en el año 2023. Se observa un predominio en hombres, mayores de 80 años, residentes en la región de Los Lagos. DISCUSIÓN: Se observa una disminución en la mortalidad por EP durante los años de pandemia SARS-COV-2, posiblemente asociado a que aquellos pacientes que padecen EP, pudiesen haber fallecido por causa respiratoria. Los hombres presentan tasas más altas, asociado a diferencias biológicas y de exposición ambiental, asimismo las regiones agrícolas como Los lagos. Se presenta un aumento estacional en invierno por las condiciones climáticas que aumentan las comorbilidades. CONCLUSIÓN: Este estudio proporciona información valiosa sobre la mortalidad por EP en Chile y destaca áreas que podrían beneficiarse de intervenciones específicas, siendo esencial para mejorar la atención y las políticas de salud en Chile.

The caregiving work experience of healthcare workers in Chile during the COVID-19 pandemic and its impact on mental health: A qualitative study based on the international initiative HEROES. / Experiencia de trabajo de cuidados de trabajadores de la salud en Chile durante la pandemia COVID-19 y su impacto en la salud mental: estudio cualitativo a partir de la iniciativa internacional HEROES.

Introduction: The COVID-19 pandemic has impacted the mental health of healthcare workers. Studying the care perspective is essential to understanding the causes of specific mental health findings and proposing strategies to address them. Methods: Cross-sectional study with a thematic analytical approach, derived from the international initiative "The Health Care Workers Study" (HEROES), conducted among healthcare workers in Chile during the second semester of 2022 and the first of 2023 through semi-structured interviews and inductive coding. Results: A narrative synthesis of 35 interviews in four themes: care at work: the presence of changes in work tasks, concern about becoming infected, collective "mystique", stigma due to being a healthcare worker, conflicts with patients; care at home: multiple ways of arranging household tasks, the relevance of living with others, interrelation with work dynamics, "double burden" among women; relationship with one's own mental health: recognition of mental health impact, the stress associated with change and uncertainty, perception of work overload, feelings of guilt or responsibility for infecting family members; and beliefs and values about the pandemic and its effects: acceptance of psychological impact on healthcare workers, organizational culture as a relevant element in postponing one's own mental health, initial disbelief in the effects of the pandemic, similarities with previous periods of social upheaval, and equality among people in terms of vulnerability to the disease. Conclusions: Five elements emerge as potential areas for intervention: gender perspective, previous exposure to crisis experiences, self-care spaces, peer support, and institutional response. The care perspective helps study the relationship between some stressors and healthcare workers' mental health in the context of a pandemic.

Introducción: La pandemia por COVID-19 ha impactado la salud mental de los trabajadores de salud. La perspectiva de cuidados se ha identificado como necesaria de estudiar, para entender causas atribuibles asociadas a hallazgos específicos en materia de salud mental y proponer cursos de acción para abordarla. Métodos: Estudio de carácter transversal con enfoque analítico temático, derivado de la iniciativa internacional (HEROES) Fue realizado entre trabajadores de salud en Chile, durante el segundo semestre de 2022 y el primero de 2023, a través entrevistas semiestructuradas y codificación inductiva. Resultados: Síntesis narrativa de 35 entrevistas, en cuatro temas: cuidados en el trabajo: presencia de cambios de funciones, preocupación por contagio, "mística" colectiva, estigma por condición de trabajador de la salud, conflictos con pacientes; cuidados en el hogar: diversas formas de arreglos de tareas domésticas, relevancia de la convivencia con otros, interrelación con dinámicas laborales, "doble carga" entre mujeres; relación con la propia salud mental: reconocimiento de afectación en salud mental, estrés asociado a cambio e incertidumbre, percepción de sobrecarga laboral, sentimientos de culpa o responsabilidad por contagio a familiares; y creencias y valores sobre la pandemia y sus efectos: aceptación de afectación psíquica de trabajadores de la salud, cultura organizacional como elemento relevante en postergación de propia salud mental, incredulidad inicial ante efectos de la pandemia, similitudes con periodos de conmoción social previos, igualdad entre personas respecto a vulnerabilidad frente a enfermedad. Conclusiones: Cinco elementos surgen como potenciales áreas de intervención: perspectiva de género, exposición previa a experiencias de crisis, espacios de autocuidado, apoyo de pares y respuesta institucional. La perspectiva de cuidados es útil para estudiar la relación entre algunos factores estresantes y la salud mental de los trabajadores de salud en el contexto de pandemia.

Efficacy, immunogenicity and safety of CoronaVac® in children and adolescents aged 6 months to 17 years: a multicenter, randomized, double-blind, placebo-controlled phase III clinical trial.

Safe and effective vaccines against COVID-19 for children and adolescents are needed. This international multicenter, randomized, double-blind, placebo-controlled, phase III clinical trial assessed the efficacy, immunogenicity, and safety of CoronaVac® in children and adolescents (NCT04992260). The study was carried out in Chile, South Africa, Malaysia, and the Philippines. The enrollment ran from September 10, 2021 to March 25, 2022. For efficacy assessment, the median follow-up duration from 14 days after the second dose was 169 days. A total of 11,349 subjects were enrolled. Two 3-µg injections of CoronaVac® or placebo were given 28 days apart. The primary endpoint was the efficacy of the CoronaVac®. The secondary endpoints were the immunogenicity and safety. The vaccine efficacy was 21.02% (95% CI: 1.65, 36.67). The level of neutralizing antibody in the vaccine group was significantly higher than that in the placebo group (GMT: 390.80 vs. 62.20, P <0.0001). Most adverse reactions were mild or moderate. All the severe adverse events were determined to be unrelated to the investigational products. In conclusion, in the Omicron-dominate period, a two-dose schedule of 3 µg CoronaVac® was found to be safe and immunogenic, and showed potential against symptomatic COVID-19 in healthy children and adolescents.

Comparative analysis of COVID-19 diagnoses and mortality among hospitalized indigenous and non-indigenous populations in Chile: 2020-2021.

BACKGROUND: Current literature presents mixed effects of the COVID-19 pandemic on Indigenous communities. We aim to highlight potential disparities and temporal shifts in both the impact of COVID-19 and vaccine uptake among hospitalized Indigenous populations in Chile. METHODS: We conducted an observational analysis utilizing 1,598,492 hospitalization records from 2020 to 2021 based on publicly accessible hospital discharge data spanning 65 healthcare facilities of medium and high complexity funded through the Diagnosis-Related Groups (DRG) mechanism in Chile, representing roughly 70% of the country's total hospitalizations. This was supplemented with publicly available municipal data on COVID-19 vaccinations and socio-demographic variables. We performed logistic regression analysis at 0.05 level of significance to assess the bivariate and multivariable association of Indigenous status with COVID-19 diagnosis and COVID-19 deaths among hospitalized populations. We also performed univariate and multiple linear regression to assess the association of COVID-19 vaccination rate and Indigenous status at the municipality level. In addition, we report the distribution of top 10 secondary diagnoses among hospitalized COVID-19 cases and deaths separately for Indigenous and non-Indigenous populations. RESULTS: Indigenous populations displayed lower adjusted odds for both COVID-19 diagnosis (OR: 0.76, 95% CI: 0.74, 0.77) and death (OR: 0.91, 95% CI: 0.85, 0.97) when compared to non-Indigenous groups. Notably, the adjusted odds ratio for COVID-19 diagnosis in Indigenous populations rose from 0.59 (95% CI: 0.57, 0.61) in 2020 to 1.17 (95% CI: 1.13, 1.21) in 2021. Factors such as the significantly higher median age and greater number of comorbidities in the non-Indigenous hospitalized groups could account for their increased odds of COVID-19 diagnosis and mortality. Additionally, our data indicates a significantly negative adjusted association between COVID-19 vaccination rates and the proportion of Indigenous individuals. CONCLUSION: Although Indigenous populations initially showed lower odds of COVID-19 diagnosis and mortality, a marked rise in diagnosis odds among these groups in 2021 underscores the urgency of targeted interventions. The observed negative association between the proportion of Indigenous populations and vaccination rates further underscores the necessity to tackle vaccine access barriers and work towards equitable distribution.

Revisiting the Link between Workplace Support for Families, Family Support, Diet Quality, and Satisfaction with Food-Related Life in the Second Year of the Pandemic.

The main objective of this study was to examine the actor and partner effects between Perceived Workplace Support for Families (PWSFs) and family support (PFS), diet quality, and satisfaction with food-related life (SWFoL) in households with both parents working and adolescents, along with the role of the three family members' diet quality as a mediator. During the second year of the pandemic in Chile, 860 dual-earner parents of different sexes and their adolescent child (average age 13 years, with 50.7% being male) were recruited from two cities. Parents responded to a measure of PWSFs and the Perceived Family Support Scale. Mothers, fathers, and adolescents answered the Adapted Healthy Eating Index (AHEI) and the satisfaction with food-related life Scale. The examination employed the mediation Actor-Partner Interdependence Model and structural equation modeling for the analyses. Results showed that mothers' PWSFs improved their and their teenage children's SWFoL, while fathers' PWSFs only improved their SWFoL. The mothers' PFS improved their and the fathers' diet quality while enhancing their SWFoL and the adolescents' SWFoL. The fathers' PFS enhanced their and the adolescents' SWFoL. The mothers' PFS also indirectly enhanced their and the fathers' SWFoL via each parent's diet quality. Each family member's diet quality was positively related to their SWFoL, while mothers' diet quality was positively related to the fathers' SWFoL. These results imply that resources obtained by parents from PFS positively impact the SWFoL of the three family members through different mechanisms. They also highlight the importance of maternal family support for SWFoL during the pandemic.

Mental Health and Suicidal Behaviour in Chilean Youth during the Covid-19 Pandemic.

BACKGROUND: The pandemic caused by the SARS-CoV-2 virus led to a series of containment and mitigation measures through lockdowns, social distancing, and the closure of educational establishments, which have had a profound impact on the mental health of the adolescent population. OBJECTIVE: The main objective of the present study has been to identify the sociodemographic and mental health variables related to suicidal ideation, planning, and attempts in young people participating in outpatient intervention projects within the Chilean protection network since the onset of the pandemic and the strictest lockdowns. METHOD: The study's sample consists of 125 young people aged 14 to 18 years (M = 15.65; SD = 1.22), participating in outpatient intervention projects within the National Service for Minors (SENAME)/Better Childhood protection network. Through a self-report survey, the young participants provided responses on sociodemographic variables and suicidal behaviour (ideation, planning, and attempts). RESULTS: 29.9% of the participants reported suicidal ideation during the onset of the pandemic and the established lockdowns; 29.2% reported having devised a plan to do so, and 18.2% indicated having attempted suicide during the evaluated period. A higher occurrence of suicidal behaviour was observed in females, sexual minorities, respondents over 15 years old, and respondents presenting depressive symptoms. CONCLUSIONS: The Covid-19 pandemic has had a significant impact on suicidal behaviour among the adolescent population served by the protection network in Chile. The prior violation of their rights may have contributed to the issue, particularly affecting young females in late adolescence with indicators of depression, who require specialized intervention due to the high risk detected.

Dynamic changes of hematological and hemostatic parameters in COVID-19 hospitalized patients: Potential role as severity biomarkers for the Chilean population.

Background: COVID-19 is still a global health issue, there is limited evidence in South America regarding laboratory biomarkers associated with severe disease. The objective of our study was to identify hematological and hemostatic changes associated with severe COVID-19. Methods: A total of 170 hospitalized patients with COVID19 were included in the study, defining their severity according to established criteria. Demographic, clinical, and laboratory (days 1, 3, 7, 15) data were obtained. We performed a statistical analysis, assuming significance with a value of p < 0.05. We analyzed the correlation between severity and biomarkers and established cut-off values for severe patients through ROC curves, estimating Odds Ratio associated with severe disease. Results: Day 1 was observed significant differences between moderate vs severe patients for leukocytes (WBC), Neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR) and D-dimer, establishing cut-off points for each of them. The markers we found associated to risk of severe disease were WBC (OR=3.2396; p = 0.0003), NLR (OR=5.7084; p < 0.0001), PLR (OR=4.4094; p < 0.0001), Neutrophil (OR=4.1193; p < 0.0001), D-dimer (OR=2.7827; p = 0.0124). Conclusions: The results allow to establish basic laboratory biomarkers associated to severe disease, which could be used as prognostic markers.

Resultados Síntesis narrativa de 35 entrevistas, en cuatro temas: cuidados en el trabajo: presencia de cambios de funciones, preocupación por contagio, "mística" colectiva, estigma por condición de trabajador de la salud, conflictos con pacientes; cuidados en el hogar: diversas formas de arreglos de tareas domésticas, relevancia de la convivencia con otros, interrelación con dinámicas laborales, "doble carga" entre mujeres; relación con la propia salud mental: reconocimiento de afectación en salud mental, estrés asociado a cambio e incertidumbre, percepción de sobrecarga laboral, sentimientos de culpa o responsabilidad por contagio a familiares; y creencias y valores sobre la pandemia y sus efectos: aceptación de afectación psíquica de trabajadores de la salud, cultura organizacional como elemento relevante en postergación de propia salud mental, incredulidad inicial ante efectos de la pandemia, similitudes con periodos de conmoción social previos, igualdad entre personas respecto a vulnerabilidad frente a enfermedad. Conclusiones Cinco elementos surgen como potenciales áreas de intervención: perspectiva de género, exposición previa a experiencias de crisis, espacios de autocuidado, apoyo de pares y respuesta institucional. La perspectiva de cuidados es útil para estudiar la relación entre algunos factores estresantes y la salud mental de los trabajadores de salud en el contexto de pandemia.

Introduction The COVID-19 pandemic has impacted the mental health of healthcare workers. Studying the care perspective is essential to understanding the causes of specific mental health findings and proposing strategies to address them. Methods Cross-sectional study with a thematic analytical approach, derived from the international initiative "The Health Care Workers Study" (HEROES), conducted among healthcare workers in Chile during the second semester of 2022 and the first of 2023 through semi-structured interviews and inductive coding. Results A narrative synthesis of 35 interviews in four themes: care at work: the presence of changes in work tasks, concern about becoming infected, collective "mystique", stigma due to being a healthcare worker, conflicts with patients; care at home: multiple ways of arranging household tasks, the relevance of living with others, interrelation with work dynamics, "double burden" among women; relationship with one's own mental health: recognition of mental health impact, the stress associated with change and uncertainty, perception of work overload, feelings of guilt or responsibility for infecting family members; and beliefs and values about the pandemic and its effects: acceptance of psychological impact on healthcare workers, organizational culture as a relevant element in postponing one's own mental health, initial disbelief in the effects of the pandemic, similarities with previous periods of social upheaval, and equality among people in terms of vulnerability to the disease. Conclusions Five elements emerge as potential areas for intervention: gender perspective, previous exposure to crisis experiences, self-care spaces, peer support, and institutional response. The care perspective helps study the relationship between some stressors and healthcare workers' mental health in the context of a pandemic.

Early mutational signatures and transmissibility of SARS-CoV-2 Gamma and Lambda variants in Chile.

Genomic surveillance (GS) programmes were crucial in identifying and quantifying the mutating patterns of SARS-CoV-2 during the COVID-19 pandemic. In this work, we develop a Bayesian framework to quantify the relative transmissibility of different variants tailored for regions with limited GS. We use it to study the relative transmissibility of SARS-CoV-2 variants in Chile. Among the 3443 SARS-CoV-2 genomes collected between January and June 2021, where sampling was designed to be representative, the Gamma (P.1), Lambda (C.37), Alpha (B.1.1.7), B.1.1.348, and B.1.1 lineages were predominant. We found that Lambda and Gamma variants' reproduction numbers were 5% (95% CI: [1%, 14%]) and 16% (95% CI: [11%, 21%]) larger than Alpha's, respectively. Besides, we observed a systematic mutation enrichment in the Spike gene for all circulating variants, which strongly correlated with variants' transmissibility during the studied period (r = 0.93, p-value = 0.025). We also characterised the mutational signatures of local samples and their evolution over time and with the progress of vaccination, comparing them with those of samples collected in other regions worldwide. Altogether, our work provides a reliable method for quantifying variant transmissibility under subsampling and emphasises the importance of continuous genomic surveillance.

Testing an online screening for autism in the COVID-19 pandemic: a psychometric study of the Q-CHAT-24 in Chilean toddlers.

Background: The aim of this study was to examine some psychometric characteristics of the Chilean-adapted version of the Quantitative Checklist for Autism in Toddlers (Q-CHAT-24) (24) in a group of unselected children (community sample). This version was administered remotely through an online version during the pandemic period to caregivers of children, aged 18-24 months, registered in four primary care polyclinics of the Health Service Araucanía Sur, Chile. Methods: An intentional non-probabilistic sampling was used. Three hundred and thirteen toddlers were examined. Participants completed an online version of the Q-CHAT-24 which was disseminated through the REDCap platform. Evidence of reliability through internal consistency and evidence of predictive validity through ROC curve analysis were realized. Results: The mean age of the children evaluated was 21.16 months. The Shapiro-Wilk test revealed that Q-CHAT-24 scores was normally distributed. 71 cases (23.12%) scored 38 points or more on the Q-CHAT-24, qualifying as Autistic Risk. 48 cases (15.63%) were confirmed as autistic through the ADOS-2 Module T. All items were positively correlated with Q-CHAT-24 total score. All items were positively correlated with Q-CHAT-24 total score. Internal consistency was acceptable for the Q-CHAT-24 (Cronbach ´s α=0.78). The internal consistencies were analyzed for the Q-CHAT-24 Factors, and they were good for factor 1 "Communication and Social Interaction" (Cronbach ´s α=0.85) and acceptable for factor 2 "Restrictive and Repetitive Patterns" (Cronbach ´s α=0.74). Receiver operating characteristic (ROC) curve analyses were performed. The AUC values were 0.93 with statistical significance (p<0.01). For the cut-off point of 38, the Sensitivity, Specificity and Youden index values were 0.89, 0.8 and 0.7, respectively. The Positive Predictive Value (PPV) was 86% and the Negative Predictive Value (NPV) was 85%. Conclusions: In accordance with the objectives of this study, evidence of reliability and predictive validity was demonstrated for the Q-CHAT-24 in this Chilean population. More importantly, this study provides Sensitivity and Specificity data for a remote application version of an autism screening tool already validated in Chile. The implications of this have to do with the possibility of establishing a remote assessment system for children at risk of autism on a population scale.

Revisiting longitudinal qualitative studies in social work: considerations for design and methodological insights.

This paper undertakes an analysis and discussion of the methodological challenges and insights derived from three longitudinal qualitative studies, all conducted in Chile during the COVID-19 pandemic and subject to comprehensive theoretical-methodological reflection processes centred on their respective designs. This analysis makes a significant contribution to interdisciplinary discussions within social research, with a particular emphasis on longitudinal trajectories. First, we present a comparative analysis of three studies in social work, utilising Saldaña's questions addressing changes and learning in longitudinal studies. The first study explores the labour trajectories of researchers, the second focuses on the educational trajectories of students, and the last examines therapeutic alliance trajectories between social workers and families within the child protection system. Following this, we delve into the methodological decisions made by the research group during the execution of these longitudinal studies. This encompasses an examination of participant involvement, temporal definitions of the adopted designs, and the most suitable methodological tools for analysing change processes over time. The outcomes of this comparative analysis reveal the distinctive characteristics of the three longitudinal studies, providing insights into how the time dimension is explored within them. We highlight key criteria essential for consideration in longitudinal qualitative research, particularly regarding participants and methodology. In conclusion, we advocate for an expanded reflection within the realm of longitudinal qualitative methodology, encompassing aspects such as design choices, approaches to data analysis, integration of technology in information processing, and strategies for maintaining participant engagement.
