Independent effect of weather, air pollutants, and seasonal influenza on risk of tuberculosis hospitalization: An analysis of 22-year hospital admission data.

BACKGROUND: While influenza infections and environmental factors have been documented as potential drivers of tuberculosis, no investigations have simultaneously examined their impact on tuberculosis at a population level. This study thereby made use of Hong Kong's surveillance data over 22 years to elucidate the temporal association between environmental influences, influenza infections, and tuberculosis activity. METHODS: Weekly total numbers of hospital admissions due to tuberculosis, meteorological data, and outdoor air pollutant concentrations in Hong Kong during 1998-2019 were obtained. All-type influenza-like illness positive (ILI+) rate and type-specific ILI+ rates were used as proxies for influenza activity. Quasi-Poisson generalized additive models together with distributed lag non-linear models were used to assess the association of interest. RESULTS: A total of 164,116 hospital admissions due to tuberculosis were notified in public settings over a period of 22 years. The cumulative adjusted relative risk (ARR) of hospital admission due to tuberculosis was 1.07 (95% CI, 1.00-1.14) when the mean ambient temperature increased from 15.1 °C (the 5th percentile) to 24.5 °C (median). Short-term exposure to air pollutants was not found to be statistically significantly related to tuberculosis hospitalization. Accounting for the environmental covariates in the analysis, the cumulative ARR of tuberculosis admission was elevated to 1.05 (95% CI, 1.01-1.08) when the rate of ILI+ total increased from zero to 19.9 per 1000 consultations, the 95th percentile. CONCLUSION: Our findings demonstrated that increased influenza activity and higher temperature were related to a higher risk of tuberculosis admissions. Stepping up the promotion of influenza vaccination, especially before the summer season, may lower the risk of tuberculosis infection/reactivation for vulnerable groups (e.g. elderly born before the launch of Bacillus Calmette-Guérin vaccination programme).

Finding the positives from the COVID-19 pandemic: factors associated with posttraumatic growth among nurses in Hong Kong.

Background: Due to active involvement with patients for COVID-19 treatments, nurses are susceptible to adverse psychological outcomes amid the COVID-19 pandemic. Despite the distress, studies have suggested that nurses are able to experience positive changes (i.e. posttraumatic growth; PTG) during the pandemic. Research on other populations has also indicated that COVID-19-specific worries and work-related coping resources are associated with people's positive changes during the pandemic. Objective: This study examined how socio-demographic characteristics, COVID-19-related worries, and work-related variables (satisfaction with work and workplace pandemic guidelines) were associated with PTG among nurses in Hong Kong. Methods: Nurses (N = 1510) working in hospitals and community settings were recruited through nursing associations in Hong Kong between 8 August 2020 and 22 September 2020. They were invited to complete a cross-sectional survey measuring their sociodemographic characteristics, COVID-19 worries, and satisfaction with work and workplace pandemic-control measures. Results: Results from hierarchical regressions found that those working non-full-time (ß = -0.06), affiliating with a religion (ß = 0.24), having higher COVID-19-related worries and psychological distress (ßs ranging from 0.12-0.15), and having higher work satisfaction (ß = 0.14) were associated with higher PTG (ps < .05). Moreover, a significant interaction between psychological distress and satisfaction with workplace pandemic control guidelines emerged in explaining PTG (ß = 0.08, p < .05), such that guideline satisfaction was only associated with higher PTG among those with higher distress (ß = 0.09, p = .03), but not those with lower distress (ß = -0.05, p > .05). Conclusions: Nurses in Hong Kong did report positive changes amid the COVID-19 pandemic. Future studies could focus on the contributing factors of PTG to design for effective strategies to enhance resources for nurses to promote positive psychosocial outcomes.

Antecedentes: Debido a la participación activa de pacientes en los tratamientos de COVID-19, las/os enfermeras son susceptibles a resultados psicológicos adversos en medio de la pandemia de COVID-19. A pesar de la angustia, los estudios han sugerido que las(os) enfermeras(os) pueden experimentar cambios positivos (es decir, crecimiento postraumático; CPT) durante la pandemia. Investigación en otras poblaciones también ha indicado que las preocupaciones específicas por COVID-19 y los recursos de afrontamiento relacionados con el trabajo están asociados a cambios positivos de las personas durante la pandemia.Objetivo: Este estudio examinó cómo las características sociodemográficas, las preocupaciones relacionadas a COVID-19 y las variables relacionadas con el trabajo (satisfacción con el trabajo y pautas pandémicas en el lugar de trabajo) se asociaron con el CPT entre las(os) enfermeras(os) de Hong Kong.Métodos: Las(os) enfermeras(os) (N = 1510) que trabajan en hospitales y entornos comunitarios fueron reclutadas(os) a través de asociaciones de enfermería en Hong Kong entre el 8 de agosto del 2020 y el 22 de septiembre del 2020. Los participantes fueron invitados a completar una encuesta transversal que midió sus características sociodemográficas, preocupaciones sobre COVID-19 y satisfacción con el trabajo y las medidas de control de pandemias en el lugar de trabajo.Resultados: Los resultados de regresiones jerárquicas encontraron que aquellos que: no trabajaban a tiempo completo (ß = −0.06), se afiliaban a una religión (ß = 0.24), tenían mayores preocupaciones y angustia psicológica relacionadas por COVID-19 (ßs que oscilan entre 0.12­0.15) y tenían una mayor satisfacción laboral (ß = 0.14), se asociaron con CPT más alto (ps < .05). Además, una interacción significativa entre la angustia psicológica y la satisfacción con las pautas de control de la pandemia en el lugar de trabajo, surgió al explicar el CPT (ß = 0.08, p < .05), de modo que la satisfacción de la guía sólo se asoció con un CPT más alto entre aquéllos con mayor angustia (ß = 0.09, p = .03), pero no en aquéllos con menor angustia (ß = −0.05, p > .05).Conclusiones: Las(os) enfermeras(os) en Hong Kong informaron cambios positivos en medio de la pandemia por COVID-19. Los estudios futuros podrían centrarse en los factores que contribuyen a la CPT para diseñar estrategias eficaces con el fin de mejorar los recursos de las(os) enfermeras(os) para promover resultados psicosociales positivos.
