- Anxiety and depression in the initial stage of the COVID-19 outbreak in a Portuguese sample: exploratory studyPublication . José, Helena; Oliveira, Cláudia; Costa, Emília; Matos, Filomena; Pacheco, Eusébio; Nave, Filipe; Valentim, Olga; Sousa, LuísIn previous studies, it was found that the confinement to which the population was subjected during the quarantine of the COVID-19 pandemic increased the risk of anxiety and depression. Objective: to analyze the levels of anxiety and depression symptoms in Portugal residents during the quarantine of the COVID-19 pandemic. Methods: This is a descriptive, transversal, and exploratory study of non-probabilistic sampling. Data collection was carried out between 6th and 31st of May 2020. Sociodemographic and health questionnaires PHQ-9 and GAD-7 were used. Results: The sample consisted of 920 individuals. The prevalence for depressive symptoms (PHQ-9 ≥ 5) was 68.2% and (PHQ-9 ≥ 10) was 34.8%, and for anxiety symptoms (GAD-7 ≥ 5) was 60.4% and (GAD-7 ≥ 10) was 20%. Depressive symptoms were moderately severe for 8.9% of the individuals, and 4.8% presented severe depression. Regarding the generalized anxiety disorder, we found that 11.6% of individuals present moderate symptoms, and 8.4% severe anxiety symptoms. Conclusions: The prevalence of depressive and anxiety symptoms were substantially higher than those previously found for the Portuguese population and when compared with other countries during the pandemic. Younger individuals, female, with chronic illness and medicated, were more vulnerable to depressive and anxious symptoms. In contrast, participants who maintained frequent levels of physical activity during confinement had their mental health protected.
- Effect of humor intervention on well-being, depression, and sense of humor in hemodialysis patientsPublication . Sousa, Luís; Antunes, Ana Vanessa; Marques-Vieira, Cristina; Silva, Paulo César Lopes da; Severino, Sandy; José, HelenaObjetivo: Evaluar si la visualización de películas de humor durante las sesiones de hemodiálisis mejora el bienestar subjetivo y el sentido del humor, al tiempo que disminuye los niveles de estrés / ansiedad y depresión, en pacientes con hemodiálisis. Material y Método: Se realizó un estudio pre-post intervención con un grupo de control no equivalente, en pacientes con enfermedad renal crónica en hemodiálisis, en dos unidades de hemodiálisis de Diaverum Clinics. El estudio incluyó a 34 pacientes en el grupo de intervención y 33 pacientes en el grupo de control. La intervención consistió en la visualización de películas de humor durante diez sesiones de hemodiálisis en un período de cuatro semanas. El grupo control vio películas neutrales. Los datos se recogieron mediante un cuestionario de información sociodemográfica y de salud (edad, sexo, nacionalidad, educación, ocupación, estado civil, duración de la sesión de diálisis, presencia de hipertensión y diabetes); la escala subjetiva de felicidad; la escala de satisfacción general con la vida; la escala de depresión, ansiedad y estrés (DASS-21) y la escala multidimensional de sentido del humor. Se emplearon pruebas t-Student y pruebas t para muestras pareadas. La respuesta al cambio se evaluó utilizando: el porcentaje de cambio, el efecto pico y el efecto base, el tamaño del efecto y la media de respuesta estandarizada. Resultados: Los niveles de felicidad subjetiva y de sentido del humor aumentaron en el grupo de intervención, pero no hubo aumento significativo en la satisfacción general con la vida. Solo los niveles de depresión disminuyeron significativamente en el grupo de intervención. Conclusiones: La visión de las películas de humor como una intervención de enfermería mejoró los niveles de felicidad subjetiva y de sentido del humor, al tiempo que disminuyó la percepción de los síntomas depresivos.
- Spatial patterns of fishing activity inside the Gorringe bank MPA based on VMS, AIS and e-logbooks dataPublication . Campos, Aida; Leitão, Pedro; Sousa, Luís; Gaspar, Patrícia; Henriques, VictorIn this study, the fishing distribution and intensity over the Gorringe bank, a large oceanic underwater mountain located in the NE Atlantic, Natura 2000 Network MPA inside Portugal's EEZ is evaluated in the period from 2012 to 2016. Based on the combined analysis of fisheries-dependent data comprising Vessel Monitoring System (VMS), Automatic Identification System (AIS) and electronic logbooks available for the Portuguese fleet oper-ating within the area, it was possible to identify fishing trips and fishing events and define fishing trajectories, allowing the estimation of the fishing effort and the CPUE at a high spatial resolution. A total of 32 Portuguese vessels were identified to have undertaken fishing activity within the limits of this MPA, mainly longliners based on mainland ports, operating drifting and bottom longlines on a seasonal basis. Fleet-related differences in the distribution and intensity of fishing effort and CPUE for the main target species were addressed. The bottom longline activity concentrated, as expected, around the two seamount summits, where the presence of VMEs and sensitive habitat-forming species have been registered. The analysis of AIS data, the only dataset made available in this study for non-Portuguese vessels, strongly suggests that the foreign fleet operating within the Gorringe MPA represents a significant fraction of the fishing activity in the area. If assessing the fishing impacts is deemed as an important objective in the management of this MPA, then the results obtained in this study can be a valuable contribution towards the environmental protection of this oceanic seamount.
