Background: Malnutrition is a recurrent problem that has acquired its own identity in recent years. The aim of this study is to assess the risk of malnutrition and nutritional status on admission and its evolution until discharge in patients aged 65 and over admitted to medical and surgical hospitalization units in hospitals of the Spanish National Health System. Methods: Prospective observational study to be carried out in the medical-surgical hospitalization units of 9 public hospitals between 01/09/2022 and 31/12/2024. Using consecutive sampling, a total of 4077 patients will be included (453 in each hospital). Variables included are related to the care process, functionality, cognition and comorbidity, risk profile, nutritional status and dysphagia; as well as frailty, dietary quality and contextual variables. The incidence of risk of malnutrition, undernutrition and dysphagia during the care process and at discharge will be calculated. The association with risk factors will be studied with logistic regression models and multivariate Cox regression models. In addition, an analysis of participants' satisfaction with food services will be carried out. Discussion: Some studies address nutritional status or dysphagia in older people in various care settings. However, there is a lack of large sample studies including both processes of the impact of hospitalization. The results of the project will provide information on the incidence and prevalence of both pathologies in the study subjects, their associated factors and their relationship with the average length of stay, mortality and early readmission. These results will serve to improve their health status. Trial registration: The study was approved by the Ethics and Research Committee on 30/09/2020, approved for funding on 02/12/2021 and with registration number RBR-5jnbyhk in the Brazilian clinical trials database (ReBEC) for observational studies.

Falls have a considerable impact on the functional prognosis of older adults. The main focus of this multicenter, retrospective, observational study was to examine the prevalence of falls in Spanish people aged 65−80 years still living at home. The secondary aims included examining the overall sociodemographic and clinical variables associated with a history of falls and then stratifying these findings by sex.We also aimed to determine the differences between sexes with regard to the history and consequences of falls and to evaluate associations between fall history and functional performance tests. The 747 older adults had all participated in the otago exercise program, which is a progressive home program of strength, balance, and endurance exercises. They were recruited by nurses in 21 primary care centers in 10 Spanish provinces between September 2017 to December 2018. The participants' mean age was 72.2 (SD: 4.3) years, and 67% were women. We recorded sociodemographic and clinical variables, functional performance test results, and any falls and/or injuries in the last 12 months. We found that 32% had fallen, 36% of those had fallen more than once, and 48% had sustained injuries when they fell. The bivariate analysis showed that women had more than twice the odds of falling than

IntroductionMild cognitive impairment is one of the consequences of ageing, causing functional disability, a poor quality of life and an increased socioeconomic expenditure. Evidence shows that patients go through a long preclinical stage in which cognitive deficits appear subtly until they reach the threshold of dementia. Non-pharmacological interventions have been gaining ground as prevention of modifiable factors of cognitive decline such as obesity, diabetes, physical inactivity or social isolation. Along these lines, Information and Communication Technologies (ICTs) can be a tool for cognitive stimulation, cognitive training and cognitive rehabilitation. The main objective of the systematic review will be to review and analyse the use of ICTs for the improvement of cognitive functions in healthy older adult population aged 50 and over, for the prevention of cognitive impairmentMethodsA systematic review will be conducted including randomised clinical trials in adults without diseases or accidents associated with cognitive impairment, and whom have used ICTs for the improvement of cognitive functions between 2010 and 2020 in English or Spanish. The articles that report data on cognitive function by domain, for example, memory or executive functions, or by test will be included. The databases Medline (PubMed), CinahlPlus, Scopus, ISI WoS, CENTRAL and IEEE Xplore will be searched. Studies that meet the inclusion criteria will be analysed according to the Cochrane RoB2 tool for risk of bias assessment.Ethics and disseminationEthical approval is not necessary as this is a systematic review. The results will be published in scientific journals, as well as in specialised congresses on the subject of study.
