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.

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. [ABSTRACT FROM AUTHOR]

Introduction: 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. [ABSTRACT FROM AUTHOR]
