The impact of docosahexaenoic acid on maternal mental health: scoping review.

Introduction: Docosahexaenoic acid (DHA) is a polyunsaturated essential fatty acid from the omega-3 series that appears to be key to perinatal mental health. For this, the aim of this review is to evaluate the effect of DHA on maternal mental health during pregnancy and lactation with respect to depression and anxiety. The present scoping review was carried out following the methodology of Arksey and O'Malley (2005). The selection of studies was carried out in accordance with PRISMA by means of systematic searches in the PubMed, Scopus, PsycINFO and Medline databases. The results classified according to the effectiveness of DHA. In most (n = 9) of the 14 studies finally included, DHA plasma levels with or without other polyunsaturated omega-3 fatty acids were significantly lower in pregnant women with depressive and anxiety symptoms. However, no study reported a beneficial effect of DHA on mental health during the postpartum period. The majority used detection method was the Edinburgh Postpartum Depression Scale (n = 11). The prevalence of depressive symptoms ranged between 5.9 % and 50 %. As a conclusion, although more research is needed in this area, these exploratory results suggest that DHA could play an important role in preventing the pathogenesis of depression and anxiety during gestation.

Introducción: El ácido docosahexaenoico (DHA) es un ácido graso esencial poliinsaturado de la serie omega-3 que parece ser clave para la salud mental perinatal. Por ello, el objetivo de esta revisión es evaluar el efecto del DHA sobre la salud mental materna durante el embarazo y la lactancia con respecto a la depresión y la ansiedad. La presente revisión se llevó a cabo siguiendo la metodología de Arksey y O'Malley (2005). La selección de estudios se realizó de acuerdo con PRISMA mediante búsquedas sistemáticas en las bases de datos PubMed, Scopus, PsycINFO y Medline. Los resultados se catalogaron según la eficacia del DHA. En la mayoría (n = 9) de los 14 estudios finalmente incluidos, los niveles plasmáticos de DHA con o sin otros ácidos grasos omega-3 poliinsaturados fueron significativamente más bajos en mujeres embarazadas con síntomas de depresión y ansiedad. Sin embargo, ningún estudio informó un efecto beneficioso del DHA sobre la salud mental durante el periodo posparto. El método de detección más utilizado fue la Escala de Depresión Posparto de Edimburgo (n = 11). La prevalencia de síntomas depresivos osciló entre el 5,9 % y el 50 %. Como conclusión, aunque se necesita más investigación en este ámbito, los resultados exploratorios parecen indicar que el DHA juega un papel importante en la prevención de la patogenia de la depresión y la ansiedad durante el periodo de gestación.

Psychological Well-Being in Nursing Students: A Multicentric, Cross-Sectional Study.

In addition to complying with strict academic standards, nursing students must acquire relevant knowledge and skills, and learn how to carry themselves in different and often stressful professional settings. These obligations could severely affect their mental health. The purpose of this study was to examine the mental health status of undergraduate nursing students and related factors. A total of 1368 nursing students from different universities in Spain and Chile were included in this study, which took place over the 2018-2019 academic year. We assessed their levels of stress related to specific learning methodologies and determined their mental health status using the General Health Questionnaire (GHQ-28). The results revealed that the more advanced the course was, the lower the total GHQ-28 score. The stress generated by different types of training activities had a significant effect on the total GHQ-28 score. These results suggest that nursing education could act as a protective factor against mental health disorders. Although a heavy academic workload could lead to higher levels of stress, overall, it seems that mental health is better in more advanced courses than in initial academic years.

Experiences, emotional responses, and coping skills of nursing students as auxiliary health workers during the peak COVID-19 pandemic: A qualitative study.

The COVID-19 crisis in Spain has exacerbated the shortage of nursing staff to respond to increasing healthcare demands. For this reason, nursing students were requested to collaborate voluntarily as auxiliary health staff. This emergency has led to mental health problems in health professionals, hence the relevance of coping techniques. The objectives of this study were to explore the experiences and emotional responses of final-year nursing students who volunteered to carry out healthcare relief tasks during the peak of the COVID-19 pandemic, and to identify the coping strategies they adopted to deal with this situation. A qualitative study was conducted in the constructivist paradigm. Purposive sampling was used, and twenty-two students participated in semi-structured interviews, which were then content-analysed. The study is reported using the COREQ checklist. Five themes emerged in the 'Experiences and emotional response' dimension (context, patients, emotions and feelings, risk of contagion, and personal satisfaction), and three themes emerged in the 'Coping strategies' dimension strategies in the work environment, in daily life and personal life. Although the students expressed negative emotions due to the highly complex context and lack of professional experience, they evaluated the experience positively in terms of learning and usefulness. Most notably, the students employed adaptive coping strategies to deal with the pandemic.

Análisis de la deshidratación de adultos mayores en una residencia geriátrica de España: prevalencia y factores asociados / Analysis of dehydration in older people in a nursing home in Spain: prevalence and associated factors

INTRODUCCIÓN: la deshidratación en las personas mayores institucionalizadas es un problema poco explorado, no habiéndose encontrado evidencia al respecto en relación con las personas mayores del contexto residencial español. OBJETIVOS: estimar la prevalencia de la deshidratación e identificar los factores asociados a la misma en las personas mayores institucionalizadas en una residencia geriátrica. MÉTODOS: estudio descriptivo y transversal. La deshidratación se midió a través del color de la orina. Para la identificación de los factores se seleccionaron variables sociodemográficas, clínicas, funcionales y mentales. RESULTADOS: la muestra total estudiada fue de 96 individuos con una media de edad de 86,6 años (± 7,1), de los cuales el 80,2 % eran mujeres. La prevalencia de la deshidratación fue del 31,3 % (IC 95 %: 22,0 a 40,6). Los factores que se asociaron independientemente a la deshidratación fueron la presencia de ojos hundidos (OR = 8,67; p = 0,004), la baja ingesta hídrica (OR = 3,96; p = 0,041) y el deterioro funcional (OR = 0,97; p = 0,012) y cognitivo (OR = 1,10; p = 0,009). CONCLUSIONES: este estudio permite visibilizar el problema de la deshidratación en las personas mayores institucionalizadas en España. La tabla de colores de la orina puede emplearse de forma rutinaria, no invasiva y con bajo coste, por lo que podría ser el método de elección para la detección de la deshidratación en esta población. Teniendo en cuenta que la deshidratación crónica es la más prevalente en las personas mayores, la identificación de los factores asociados es clave para mejorar su hidratación

BACKGROUND: dehydration in institutionalized elderly people has not been extensively studied. There are not clear data on the Spanish context. AIM: to estimate the prevalence of dehydration and to identify the associated factors in institutionalized older people in a nursing home. METHODS: a cross-sectional study was carried out. Dehydration was measured through the colour of urine. For the identification of the associated factors, sociodemographic, clinical, functional, and mental variables were selected. RESULTS: the total sample studied was comprised of 96 individuals with a mean age of 86.6 years (± 7.1), of whom 80.2 % were women. The prevalence of dehydration was 31.3% (95 % CI, 22.0 to 40.6). The factors that were independently associated with dehydration were the presence of sunken eyes (OR = 8.67; p = 0.004), low fluid intake (OR = 3.96; p = 0.041), and both functional (OR = 0.97; p = 0.012) and cognitive (OR = 1.10; p = 0.009) impairment. CONCLUSIONS: this study highlights the problem of dehydration in institutionalized older people in Spain. An urine colour table may be used routinely, non-invasively, and cheaply. So, it may well be the best simple method for detecting dehydration in this population. Taking into account that chronic dehydration is most prevalent in elderly people, the identification of associated factors is a key factor for a successful approach

The influence of COVID-19 on the mental health of final-year nursing students: comparing the situation before and during the pandemic.

The COVID-19 pandemic has had an important impact on the academic world. It is known that university studies can influence the mental health of students, and especially those studying health sciences. In this study, we therefore sought to analyse whether the current pandemic has affected the mental well-being of final-year nursing students. This was a multi-centre study, with a descriptive, longitudinal, and prospective design. Mental well-being was evaluated using the General Health Questionnaire. A total of 305 participants were included in the study, of whom 52.1% had experienced the COVID-19 pandemic. Statistically significant differences were found between the two groups analysed in terms of age, access to university, average marks, mental well-being self-esteem, emotional exhaustion, and sense of coherence. In the case of mental well-being, a direct association was found with both the pandemic situation (OR = 2.32, P = 0.010) and emotional exhaustion scores (OR = 1.20, P < 0.001), while an inverse association was found with sense of coherence scores (OR = 0.45, P < 0.001). This study shows that the mental health of students is a significant factor and one that must be taken into consideration when training nursing staff at university. There is a need to promote healthy habits and provide appropriate coping strategies. It is also important to train and prepare students for pandemic situations as these can have an important impact on the mental health of both the members of the public who will be treated by these future nursing professionals and the students themselves.

Prevalence and Risk Factors Associated With Low Fluid Intake in Institutionalized Older Residents.

OBJECTIVE: The aim of this study was to determine the prevalence of low fluid intake in institutionalized older residents and the associated factors. DESIGN: This was a cross-sectional study. SETTING AND PARTICIPANTS: The study was carried out at a nursing home with a capacity for 156 residents, all of whom were older than 65 years. MEASURES: Data were collected on the fluids consumed by each resident over a period of 1 week. Information relating to sociodemographic variables and to residents' health, nutrition, and hydration status was also collected. RESULTS: Of 53 residents, 34% ingested less than 1500 mL/d. The factors with the greatest correlation associated with low fluid intake were cognitive and functional impairment, the risk of suffering pressure ulcers, being undernourished, a texture-modified diet, dysphagia, impaired swallowing safety, and BUN:creatinine ratio. CONCLUSIONS/IMPLICATIONS: The results obtained highlight the scale of low fluid intake in nursing homes and also aid to identify and understand the factors associated with this problem. The findings could help us to develop specific strategies to promote the intake of liquids and thereby reduce the incidence of dehydration in nursing homes.

[How to improve hydration and fluid intake in institutionalized older people? A scientific literature review]. / ¿Cómo mejorar la hidratación y la ingesta hídrica en las personas mayores institucionalizadas? Una revisión de la literatura científica.

BACKGROUND: residents are vulnerable to suffer of dehydration due to physiological changes and the physical and cognitive limitations. AIM: to handle this situation, it has been decided to evaluate the interventions which are carried out for the management of dehydration and low fluid intake in older people living in nursing homes. METHODS: the revised scientific literature review methodology of PRISMA was applied. An electronic database search was performed in PubMed, Scopus, CINAHL and other sources databases. The literature search was carried out between October 2016 and January 2017. Out of a total of 3,379 articles extracted, eleven studies were selected for analysis. In addition, their quality was assessed through Cochrane and the Newcastle-Ottawa Scale. RESULTS: the risk of bias in the studies was mostly medium. Regarding the results, the interventions were classified according to whether they were invasive or non-invasive. Invasive interventions were intravenous and/or subcutaneous fluid therapy. Their effectiveness was related to the clinical improvement of dehydration. However, local reactions appeared. Non-invasive interventions focused on the individualized assistance, the stimulation to drink more and the consideration of the preferences of each resident, producing an increase in fluid intake and an improvement in analytical parameters. CONCLUSIONS: given the peculiarities of the institutionalized elderly population, both types of intervention have been shown to have a positive effect on improving hydration. Nonetheless, non-invasive interventions have confirmed to be more efficient given their simplicity of application and cause fewer adverse effects.

INTRODUCCIÓN: los residentes son vulnerables a sufrir deshidratación por los cambios fisiológicos y las limitaciones físicas y cognitivas que padecen. OBJETIVO: para manejar esta situación, se ha decidido evaluar las intervenciones que se llevan a cabo para el manejo de la deshidratación y la baja ingesta hídrica en las personas mayores institucionalizadas en residencias geriátricas. MÉTODOS: se realizó una revisión de la literatura científica siguiendo la metodología PRISMA mediante búsquedas sistemáticas en las bases de datos PubMed, Scopus, CINAHL y otras fuentes. De un total de 3.379 artículos extraídos, se seleccionaron once estudios para su análisis. Además, se avaluó su calidad a través de Cochrane y la Newcastle-Ottawa Scale. RESULTADOS: el riesgo de sesgo de los estudios fue medio en su mayoría. En cuanto a los resultados, las intervenciones se clasificaron según fuesen invasivas o no invasivas. Las intervenciones invasivas fueron la sueroterapia intravenosa y/o subcutánea y su efectividad estuvo relacionada con la mejora clínica de la deshidratación. No obstante, aparecieron reacciones locales. Las no invasivas se centraron en la asistencia individualizada, la estimulación para beber más y tener en cuenta las preferencias de cada residente, produciendo un aumento de la ingesta y una mejora en los parámetros analíticos. CONCLUSIONES: dadas las peculiaridades de la población mayor institucionalizada, ambos tipos de intervención han demostrado tener un efecto positivo en la mejora de la hidratación. No obstante, las intervenciones no invasivas han confirmado ser más eficientes dada su sencillez de aplicación y provocar menos efectos Adversos.

Risk factors associated with dehydration in older people living in nursing homes: Scoping review.

BACKGROUND: Dehydration in the older people is a prevalent problem that is often associated with physiological changes, physical limitations and environmental conditions. OBJECTIVES: The scoping review was carried out to identify risk factors associated with dehydration in older people living in nursing homes. DESIGN: The revised scoping methodology framework of Arksey and O'Malley (2005) was applied. Study selection was carried out in accordance with Davis et al. (2009) and focused on the inclusion criteria (people over 65 years old and living in nursing homes). Risk factors were classified using the geriatric assessment. DATA SOURCES: An electronic database search was performed in PubMed, Scopus and CINAHL. The literature search was carried out between October 2016 and January 2017. REVIEW METHODS: Thematic reporting was performed and study findings were validated through interdisciplinary meetings of experts. The quality of the papers consulted was also evaluated using the Newcastle-Ottawa Scale adapted for cross-sectional, cohort and case-control studies. RESULTS: In all, 16 papers were analysed, all of which were observational studies. The risk of bias ranged from very low (n = 1), to medium (n = 13) and high (n = 2). The risk factors were classified in line with the different components of the geriatric assessment. In the socio-demographic characteristics age and gender were identified. In the clinical component, infections, renal and cardiovascular diseases and end-of-life situations were the most common factors highlighted in the papers analysed. With reference to the functional component, its limitation was associated with dehydration, while for factors of mental origin, it was related to dementia and behavioural disorders. Finally, the factors relating to the social component were institutionalisation, requiring a skilled level of care and it being winter. CONCLUSIONS: The most commonly repeated factors highlighted in the review were age, gender, infections, end of life and dementia, with it being important to highlight the large number of factors in the clinical component. Even so, the great majority of the factors were unmodifiable conditions associated typically associated with the physiology of ageing.

Fear of falling in community-dwelling older adults: A cause of falls, a consequence, or both?

BACKGROUND: Despite the number of studies that have tried to demonstrate that there is an association between previous falls and the fear of falling, the relationship between these two variables remains a matter of controversy. OBJECTIVES: Our objective was to investigate whether the fear of falling is a cause of falls, a consequence, or both in community-dwelling adults aged ≥ 75 years old. METHODS: A descriptive, longitudinal, prospective study was performed. A total of 640 individuals were interviewed between 2009 and 2011. Sociodemographic data, health status, history of falls and fear of falling were assessed at baseline and at 24 months. RESULTS: The prevalence of falls at baseline was 25% as opposed to 35.2% at 24 months. The prevalence of the fear of falling was 41.5% at baseline. Logistic regression analysis showed a significant association between a history of falls and the fear of falling. Other factors associated with the fear of falling were female gender, comorbidity, depressive symptoms, and disability. In total, 41.7% of the subjects who had reported a fear of falling at baseline had suffered at least one fall 24 months later. Unadjusted Cox regression analysis revealed that the fear of falling was a risk factor for falls. According to the final model adjusted for other covariates, the only reliable predictor was female gender. The Cox model stratified by gender failed to show a crude association between fear of falling and falls. CONCLUSION: A previous history of falls in the previous year was a good predictor of the fear of falling; but the fear of falling was a predictor of falls during follow-up only in the unadjusted model, pointing to strong gender turns out as an effect modifier of the association of FOF and subsequent falls. Nursing staff working in elderly care should not only routinely assess patients' previous history of falls, but also evaluate their fear of falling and its associated factors.

Differences in fitness level between women aged 60 and over participating in three different supervised exercise programs and a sedentary group.

The aim of this study was to compare fitness levels in women aged 60 and over participating in a supervised exercise program (involving tai chi, recreational gymnastics, and/or aquatic fitness) with those in a sedentary group. An observational, descriptive, cross-sectional study was performed on a total of 171 women aged from 60 to 92 who attended public community clubs for older adults. The instruments used included the Senior Fitness Test, the Tinetti Balance Assessment Tool, the Katz Index, and the Lawton & Brody Activities of Daily Living Scale. Significant differences in fitness levels were observed when we compared the exercise groups with the sedentary group. Women with better fitness levels had a lower risk of suffering falls and greater autonomy in performing activities of daily living and instrumental activities of daily living. Agility and gait control were found to be independently associated with exercise groups.

Asociación entre el Mini Nutritional Assessment y el índice de fragilidad de Fried en las personas mayores que viven en la comunidad / Association between Mini Nutritional Assessment and the Fried frailty index in older people living in the community

Fundamento y objetivo: Valorar la asociación entre el Mini Nutritional Assessment (MNA) y el índice de fragilidad de Fried en las personas mayores que viven en la comunidad. Material y método: Estudio transversal en individuos de 75 años o más, residentes en la comunidad. Como variables se incluyeron el estado nutricional medido a través del MNA y su forma abreviada, el Mini Nutritional Assessment Short Form (MNA-SF), y el índice de fragilidad a través de los criterios de Fried. Resultados: La muestra fue de 640 individuos, con media (DE) de edad de 81,3 (5,0) años; el 39,7% eran varones. Según el MNA-SF, el 76,9% de los individuos estaban bien nutridos, el 19,8% en riesgo de desnutrición y el 1,9% desnutridos, mientras que según el MNA, dichos porcentajes fueron del 78,1, 19,6 y 2,3%, respectivamente. Según los criterios de Fried, el 43,4% eran no frágiles, el 47%, prefrágiles, y el 9,6%, frágiles. La mayor proporción de sujetos frágiles se encontraban en riesgo de desnutrición. La puntuación del MNA y del MNA-SF en los sujetos frágiles fue significativamente menor que en los prefrágiles y no frágiles. A medida que aumentaba la puntuación de los componentes del MNA, aumentaba el índice de fragilidad. Así mismo, existía una asociación significativa entre los 5 criterios de fragilidad y las categorías del MNA y el MNA-SF. El área bajo la curva ROC para el MNA-SF fue de 0,75, mientras que para el MNA fue de 0,80. Conclusiones: Los resultados presentados ponen de manifiesto la clara asociación entre el MNA y los criterios de Fried. También evidencian que la categoría del MNA «riesgo de desnutrición» es la que está más fuertemente asociada al índice de fragilidad (AU)

Background and objective: To assess the association between Mini Nutritional Assessment (MNA) and the Fried frailty index in older people living in the community. Material and method: Cross-sectional study of individuals aged 75 and over living in the community. Variables: nutritional status measured by Mini Nutritional Assessment Short Form (MNA-SF) and MNA, and frailty measured by Fried’s frailty criteria. Results: The sample consisted of 640 individuals with a mean age of 81.3 5.0 years; 39.7% were men. According to the MNA-SF, 76.9% of patients were well nourished, 19.8% were at risk of malnutrition and 1.9% were malnourished, while percentages were 78.1, 19.6 and 2.3%, respectively, according to the MNA. According to Fried criteria, 43.4% were not frail, 47% were pre-frail and 9.6% were frail. The largest proportion of frail subjects were at risk of malnutrition. The higher the score of MNA components, the higher was the frailty index. Likewise, there was a significant association between the 5 frailty criteria and the categories of MNA and MNA-SF. The area under the ROC curve for the MNA-SF was 0.75 while for the MNA it was 0.80. Conclusions: The results presented show a clear association between Mini Nutritional Assessment and Fried’s criteria. They also suggest that the «nutritional risk» MNA category is the one most strongly associated with the Fried’s frailty index (AU)
