RESUMO

The use of pyrethroids in aquaculture has been an important component of achieving a thriving salmon farming industry in Chile. While the residual presence of such substances is known to depend on environmental conditions, most ecotoxicological studies to date have not considered environmental context. Here, we conducted oceanographic monitoring combined with experiments aiming to estimate the effects of two pyrethroids on the feeding rates of larvae of farmed mussels, Mytilus chilensis. In additional experiments, mussel spats were exposed to both pyrethroids, but under contrasting temperature/pH so as to mimic winter and summer conditions. Experiments mimicking spring conditions revealed that both pyrethroid substances affected the feeding of mussel larvae as a function of concentration. Conversely, significant impact of pyrethroids on adults were not observed with regard to temperature and pH, but a significant impact of low temperature/low pH condition on ingestion rates was confirmed. Given the current status of increasing ocean acidification, the results of this study are expected to provide useful information with regard to achieving sustainable mussel aquaculture, especially considering both activities occur in similar geographic areas, and the expansion of salmon farming areas is ongoing in Chile.

RESUMO

Los Trastornos musculoesqueléticos (TME) abarcan más de 150 patologías que pueden afectar al sistema locomotor, siendo considerado por la Organización Mundial de la Salud (OMS) en el año 2021 como el principal factor para la incapacidad laboral y de requerir rehabilitación. Estas lesiones se presentan de forma repentina y pueden llegar a ser enfermedades crónicas, las cuales pueden afectar de una manera social, económica y laboral. Objetivo. Establecer la prevalencia de las alteraciones musculoesqueléticas más frecuentes, asociadas a incapacidad laboral en pacientes que asisten al Centro de Salud en la provincia del Guayas. Materiales y métodos. Este trabajo de investigación tiene un alcance descriptivo observacional, de enfoque cuantitativo con un diseño no experimental de corte transversal, el mismo que se apoyó en una base de datos de tipo numérico. Resultados. Obteniendo como resultado una mayor prevalencia en el dolor articular con un 32,49%, seguido de lumbalgia 14,13%, patologías artrósicas 13.73% y dorsalgia 2,62%. Conclusiones. Al realizar la comparación entre varios estudios se pudo determinar que la edad más frecuente para presentar alteraciones musculoesqueléticas es de los 30 a 70 años de edad dentro de la población laboral, siendo a mayor edad, mayor prevalencia a incapacidad laboral.

Musculoskeletal disorders (MSDs) encompass more than 150 pathologies that can affect the locomotor system, being considered by the World Health Organization (WHO) in the year 2021 as the main factor for work incapacity and requiring rehabilitation. These injuries occur suddenly and can become chronic diseases, which can affect socially, economically and occupationally. Objective. To establish the prevalence of the most frequent musculoskeletal alterations associated with incapacity for work in patients attending the Health Center in the province of Guayas. Materials and methods. This research work has a descriptive observational scope, with a quantitative approach and a non-experimental cross-sectional design, which was supported by a numerical database. Results. Obtaining as a result a higher prevalence of joint pain with 32.49%, followed by low back pain 14.13%, osteoarthritic pathologies 13.73% and dorsalgia 2.62%. Conclusions. When comparing several studies, it was possible to determine that the most frequent age for presenting musculoskeletal alterations is between 30 and 70 years of age within the working population, the older the age, the higher the prevalence of incapacity for work.

Essas lesões ocorrem repentinamente e podem se tornar doenças crônicas, que podem afetar social, econômica e profissionalmente. Objetivo. Estabelecer a prevalência dos distúrbios musculoesqueléticos mais frequentes associados à incapacidade de trabalho em pacientes que frequentam o Centro de Saúde na província de Guayas. Materiais e métodos. Este trabalho de pesquisa tem um escopo observacional descritivo, com uma abordagem quantitativa e um projeto transversal não-experimental, que foi apoiado por um banco de dados numérico. Resultados. Obtendo como resultado uma maior prevalência de dores articulares com 32,49%, seguida de dores lombares baixas 14,13%, patologias artríticas 13,73% e dores nas costas 2,62%. Conclusões. Uma comparação entre vários estudos mostrou que a idade mais frequente para apresentar distúrbios musculoesqueléticos é entre 30 e 70 anos de idade na população trabalhadora, sendo que quanto maior a idade, maior a prevalência de incapacidade para o trabalho.

RESUMO

Resumen Existen diversas problemáticas que afectan la salud y el desempeño de un cuidador. El objetivo del presente estudio fue identificar la relación entre síntomas de depresión de los cuidadores primarios informales y la dependencia que perciben en la persona cuidada. El diseño del estudio fue no experimental, transversal y correlacional. La muestra fue no probabilística, intencional, de 259 cuidadores informales. Se utilizó el Cuestionario sobre la salud del paciente, Escala de Depresión (PHQ-8) y la Escala de Barthel, empleada para medir la capacidad de la persona para realizar 10 actividades básicas de la vida diaria. La edad promedio de los cuidadores de este estudio fue de 49.6 años, con predominio del sexo femenino, con 82.6 %; en el parentesco del cuidador, en su mayoría fueron hijas (38.2 %). El porcentaje de dependencia percibida por los cuidadores se ubicó en la categoría de dependencia moderada, con el 32.4 %. Los resultados muestran una correlación pequeña pero significativa (r = - 0.159, P = 0.010) entre dependencia y síntomas de depresión. El grupo de cuidadores de personas con dependencia severa presentó mayor sintomatología depresiva que sus pares cuidadores de personas con dependencia moderada (P = 0.014). Los cuida dores primarios informales reportaron mayor sintomatología depresiva cuando percibieron más dependencia en sus familiares con enfermedades crónicas.

Abstract There are various problems that affect a caregiver's health and performance. Therefore, the objective of the study was to identify the relationship between depression symptoms of the informal primary caregivers and the dependency that they perceive in the person who is being taken care of. The study design was non-experimental, cross-sectional and correlational. The sample was intentional non-probabilistic of 259 informal caregivers. Three data-collection instruments were used: the Patient Health Questionnaire, the Depression Scale (PHQ-8), and the Barthel Scale, which is used for measuring the capacity of a person to carry out 10 basic everyday activities. The average age of the caregivers in this study was 49.6 years, with a predominance of the female sex (82.6 %), and most of the patients' caregivers were their daughters (38.2 %). The caregivers' perceived percentage of dependence was placed in the moderate dependence category, with 32.4 %. Results show a small but significant correlation (r = - 0.159, P = 0.010) between dependence and symptoms of depression. The group of caregivers of people with severe dependence showed greater depressive symptoms than their caregiver peers of people with moderate dependence (P = 0.014). Informal primary caregivers reported greater depressive symptoms when they perceived more dependence in their relatives with chronic illnesses.
