The COVID-19 pandemic has had a significant impact on populations at an economic, health, and on an interpersonal level, it is still unclear how it has affected health-risk behaviors, such as comfort ...food consumption over time. This study longitudinally examines the effect of the perceived impact of COVID-19 on comfort food consumption and whether this effect is mediated by emotional distress. A convenience sample of 1048 students and university staff (academic and non-academic) from two universities completed monthly online surveys during the COVID-19 pandemic across six waves (W; W1 to W6). Participants reported their perceived impact of COVID-19 (economic, interpersonal, and health), comfort food consumption, and emotional distress (DASS-21). Using structural equation models, we found an indirect longitudinal effect of the perceived impact of COVID-19 (W1) on comfort food consumption (W3 to W6) through increased emotional distress (W2). The perceived negative impact of COVID-19 on comfort food consumption was fully mediated by the emotional distress during the first waves (W3 and W4), ending in a partial mediation in the last waves (W5 and W6). These findings contribute to disentangling the mechanisms by which the perceived impact of COVID-19 affects comfort food consumption over time, and highlight the role of emotional distress. Future interventions should address comfort food consumption by focusing on handling emotional distress during a crisis.
El siguiente artículo presenta el caso del Mercado Central de Concepción y de su erróneamente atribuida autoría al arquitecto húngaro y ex alumno de la escuela Bauhaus, Tibor Weiner. En ese ...sentido, se busca articular una nueva narrativa historiográfica del complejo, que desde 2014 está declarado Monumento Histórico, introduciendo nuevos referentes desde donde pensar este mercado: la arquitectura colonial y una relación con la arquitectura en madera. La metodología se basa en la revisión de fuentes históricas inéditas y el análisis de la forma construida. En definitiva, el trabajo se sitúa en la intersección de la historia transnacional y vernácula de la arquitectura moderna.
Abstract
The COVID-19 pandemic has had a significant impact on daily life, affecting both physical and mental health. Changes arising from the pandemic may longitudinally impact health-related ...behaviors (HRB). As different HRBs co-occur, in this study, we explore how six HRBs - alcohol (past-week and binge-drinking), tobacco, marijuana, benzodiazepine use, and unhealthy food consumption - were grouped and changed over time during the COVID-19 pandemic. A sample of 1038 university students and staff (18 to 73 years old) of two universities completed an online psychometrically adequate survey regarding their recalled HRB (T0, pre-COVID-19 pandemic) and the impact of COVID-19 on their behaviors during July (T1) and November (T2). Latent Transition Analysis (LTA) was used to identify HRB cluster membership and how clusters changed across T0, T1, and T2. Four clusters emerged, but remained mainly stable over time: ‘Lower risk’ (65.2–80%), ‘Smokers and drinkers’ (1.5–0.01%), ‘Binge-drinkers and marijuana users’ (27.6–13.9%), and ‘Smokers and binge-drinkers’ (5.6–5.8%). Participants who moved from one cluster to another lowered their HRB across time, migrating from the ‘Binge-drinkers and marijuana users’ cluster to ‘Lower risk’. Participants in this cluster were characterized as less affected economically by the COVID-19 pandemic, with lower reported stress levels, anxiety, depression, and loneliness than the other clusters. Our results provide evidence of how HRBs clustered together and transitioned longitudinally during the COVID-19 pandemic. HRB clustering across time offers a valuable piece of information for the tailoring of interventions to improve HRB.
Congenital hypoaldosteronism is a rare autosomal recessive or dominant endocrinopathy with variable penetrance, secondary to primary defects in aldosterone synthesis that could lead to hypovolemia, ...hyponatremia, hyperkalemia, failure to thrive, microcephaly, seizures, neurodevelopmental delay, or hearing loss. We present the case of a Colombian patient with congenital hypoaldosteronism, who owns two variants in the CPY11B2 gene, and a heterozygous pathogenic variant for nonclassical congenital adrenal hyperplasia. However, the patient missed follow-up and treatment for 6 years. At the age of 7 years, he resumed medical follow-up with laboratory findings of hyperreninemia and hypoaldosteronism, as well as clinical findings of strabismus, left mixed hyperacusis, and pathological short stature (−4.3 SD). Therefore, a trial of fludrocortisone therapy was started with subsequent improvement in renin levels, weight gain, and growth velocity. After 10 months of the start of the medication, he presented hypertension. There is no literature about the late treatment of this condition for pathological short stature.
En el desarrollo del talento humano y la incidencia en el desempeño laboral en las empresas, es por la falta de personal capacitado, incumplimiento en las actividades de la organización, la carencia ...de los reglamentos del talento humano, el control inoportuno, falta de una comunicación organizativa entre los jefes y colaboradores y poca participación que permita la toma de decisiones adecuadas. Por tal razón, se pretende analizar la influencia del talento humano en el desempeño laboral de la empresa de lácteos Maribella. Se aplicó una encuesta de 15 personas y se realizó el análisis estadístico factorial exploratorio. Como resultado, los principales factores de la gestión del talento humano, fue el plan del personal, análisis y diseño de puestos, plan de desarrollo de carrera, plan de sucesiones y gestión del talento. Sin embargo, existen falencias en los factores de objetivos estratégicos, eficaz actuación y ventaja competitiva por el escaso conocimiento de los colaboradores en la trayectoria importante de la empresa, falta de evaluaciones de desempeño a los colaboradores y jefes de la empresa, metas estratégicas que les permita medir el desempeño laboral y capacitaciones desarrollo profesional.
Este trabajo analiza en el contexto costarricense, la contribución económica al hogar de las mujeres casadas o en unión libre en comparación con los ingresos que aporta su pareja. Desde una ...perspectiva de los roles de género, teoría del capital humano y aspectos relacionados con la oferta laboral femenina, se analizó, con métodos multivariados y descriptivos, qué variables influyen en la probabilidad de que la contribución de la mujer sea mayor o menor dentro del hogar. Utilizando datos de la Encuesta Nacional de Hogares de 2014, se encontró que un 51% de las mujeres casadas o en unión libre no generan ningún tipo de ingresos, lo cual evidencia una relación económica dispar en la mitad de los hogares, donde la función de proveedor queda relegada al hombre. Las labores domésticas y la cantidad de hijos impactan negativamente en la probabilidad de contribución, mientras que las mujeres con un mayor nivel educativo tienen mayor probabilidad de contribuir igualitariamente al ingreso.
The embrace of coronavirus disease 2019 (COVID-19) vaccine conspiracies has been linked to vaccine hesitancy. This study aimed to investigate the relationship between COVID-19 vaccine conspiracy ...theories and perceived vaccine effectiveness. The study utilized a longitudinal follow-up study in which adults in Chile completed surveys in December 2020 (T1) and May 2021 (T2). The psychometric properties of the five-item instrument on conspiracy theories for the COVID-19 vaccine were evaluated using data from T1 (
= 578). A confirmatory one-factor structure with suitable indicators of reliability was found. The longitudinal analysis (
= 292) revealed that conspiracy theories about the COVID-19 vaccine in T1 were associated with lower beliefs in its effectiveness in T2. However, no significant association was found between beliefs in effectiveness in T1 and conspiracy theories in T2. The study suggests that beliefs in conspiracy theories may temporally precede beliefs in vaccine effectiveness for COVID-19. The results have implications for strategies to address vaccine conspiracy beliefs and their implementation at the public policy level.
Swimmer athletes showed a decreased ventilatory response and reduced sympathetic activation during peripheral hypoxic chemoreflex stimulation. Based on these observations, we hypothesized that ...swimmers develop a diminished cardiorespiratory coupling due to their decreased hypoxic peripheral response. To resolve this hypothesis, we conducted a study using coherence time‐varying analysis to assess the cardiorespiratory coupling in swimmer athletes. We recruited 12 trained swimmers and 12 control subjects for our research. We employed wavelet time‐varying spectral coherence analysis to examine the relationship between the respiratory frequency (Rf) and the heart rate (HR) time series during normoxia and acute chemoreflex activation induced by five consecutive inhalations of 100% N2. Comparing swimmers to control subjects, we observed a significant reduction in the hypoxic ventilatory responses to N2 in swimmers (0.012 ± 0.001 vs. 0.015 ± 0.001 ΔVE/ΔVO2, and 0.365 ± 0.266 vs. 1.430 ± 0.961 ΔVE/ΔVCO2/ΔSpO2, both p < 0.001, swimmers vs. control, respectively). Furthermore, the coherence at the LF cutoff during hypoxia was significantly lower in swimmers compared to control subjects (20.118 ± 3.502 vs. 24.935 ± 3.832 area under curve AUC, p < 0.012, respectively). Our findings strongly indicate that due to their diminished chemoreflex control, swimmers exhibited a substantial decrease in cardiorespiratory coupling during hypoxic stimulation.
Swimmers present a decreased ventilatory response and reduced sympathetic activation during peripheral hypoxic chemoreflex stimulation. To determine if they also present decreased cardiorespiratory coupling, we used coherence time‐varying analysis to assess the relationship between the respiratory frequency and the heart rate time series during normoxia and hypoxia. Swimmers enhibited a lower level of cardiac sympathetic respiratory coupling during hypoxic stimulation.
(analítico)El cambio climático y el aumento de las olas de calor tienen un impacto negativo en el bienestar subjetivo de niños y jóvenes. Este estudio examinó la experiencia de bienestar en jóvenes ...chilenos frente a las olas de calor. Utilizando entrevistas y grupos focales, se seleccionaron diez participantes con diferentes trayectorias educativas y niveles de contacto con la naturaleza. Los resultados mostraron que predominaban percepciones negativas del clima y emociones displacenteras como preocupación y desmotivación. Sin embargo, se encontró que aquellos con mayor contacto con la naturaleza experimentaban un mayor bienestar subjetivo. Se concluye que las olas de calor asociadas al cambio climático afectan negativamente la salud mental, pero también se destaca el papel que desempeñan los jóvenes en las acciones de mitigación y adaptación ante el cambio climático.
Palabras clave: Bienestar subjetivo; olas de calor; cambio climático; jóvenes; ecoansiedad; investigación cualitativa.
