Effect of combined physical-cognitive training on the functional and cognitive capacity of older people with mild cognitive impairment: a randomized controlled trial.

BACKGROUND: The increase in population aging highlights the growing prevalence of mild cognitive impairment, prompting the adoption of interventions that combine physical exercise and cognitive training to improve health and cognitive performance in older adults. The aim of this study was to analyze the efficacy of a combined program on physical and cognitive health in older people with cognitive impairment. METHODS: A 12-week randomized controlled clinical trial involving 95 participants (aged 72.12 ± 4.25 years), 47 individuals participated in a control group (CG) that only underwent cognitive stimulation, while 48 individuals were in an experimental group (EG) that participated in a combined program. Balance was measured using the Tinetti scale, upper body strength was assessed with the arm curl test, lower body strength was evaluated with the 30-s chair stand test, flexibility was tested using the back scratch test and chair sit-and-reach test, physical function was measured with the Timed Up and Go test, cognitive function was assessed using the Mini Mental State Examination, cognitive impairment was evaluated with the Montreal Cognitive Assessment, verbal fluency was tested with the Isaac test, and executive functions were assessed using the Trail Making Test. RESULTS: The results of the study show significant improvements in both physical and cognitive aspects, such as balance, gait, upper and lower body strength, flexibility, physical function, cognitive function, cognitive impairment, verbal fluency, and executive functions in the group that carried out the intervention compared to the control group. CONCLUSION: A combined program for older individuals with mild cognitive impairment leads to enhancements in physical and cognitive health. These improvements underscore the importance of integrating physical exercise with cognitive training as an effective strategy for enhancing overall health and quality of life in older adults.

The differential illusion memory for high-associated abstract concepts (DIM-HA) effect.

A vast body of evidence has shown that concrete concepts are processed faster and more accurately than abstract concepts in a variety of cognitive tasks. This phenomenon is widely known as the concreteness effect, and explanations for its occurrence seem to reflect differences in processing and organization for both types of representations. While there is considerable evidence to support this concreteness effect, the nature of these differences is still controversial. In developing an explanation, we have proposed a relatively different approach from a false memory perspective using the Deese-Roediger-McDermott paradigm. To explore the implications of the association in creating false memories, we explore behavioral and electrophysiologically the false memory effect, where targets were manipulated according to their association strength and their concreteness. Results showed that false recognition rates differed significantly between concrete and abstract critical words when they were associated strongly with their respective lists, which led to a higher proportion of abstract false alarms both in behavioral and electrophysiological experiments. The principal outcome, which was called the DIM-HA effect, was discussed in terms of theories of associative activation and qualitatively different representation.

Gamification in the classroom: Kahoot! As a tool for university teaching innovation.

Objectives: The purpose of this study has been to evaluate the use of gamification in the classroom, in terms of its effects on attention, concentration, creativity, and generic capabilities, for university students enrolled in a Bachelor's degree program in Physiotherapy. Methods: An experimental design was implemented, using three groups differentiated by their time of exposure to the game (0 min, 30 min, or 60 min per week). The sample consisted of 73 s-year students from a Bachelor's degree program in Physiotherapy. The theoretical content for each class was taught during a period of 4 months, reinforced by use of the Kahoot! Online platform. Selective attention and concentration were evaluated using the d2 Test of Attention; creative intelligence using the Creative Intelligence Test (CREA); and generic capabilities using the capabilities subscale of the Student Engagement Questionnaire (SEQ). Results: The study's participants had a mean age of 19.51 ± 0.9 years, and it has demonstrated that use of Kahoot! For longer periods of time, i.e., more than 60 min per day, can improve essential skills in university students, such as attention, creativity, critical thinking, self-managed learning, adaptability, problem solving, and computer literacy. This study's results show that integrating Kahoot! Into the educational environment, especially with longer sessions that allow for deeper immersion in the game, produces benefits by stimulating various cognitive aspects and enhancing complex skills. Conclusion: This study has demonstrated that use of Kahoot! Improves key skills such as attention, creativity, and critical thinking, especially when longer sessions are used. It is also suggested that its use should be balanced with other educational activities, in order to achieve comprehensive development for the students.

Yoga as a therapeutic approach to mental health in university students: a randomized controlled trial.

Objectives: The purpose of this study has been to analyze the efficacy of a yoga-based intervention on stress, emotional wellbeing, state anxiety and trait anxiety in university students. Methods: This study was a randomized controlled trial. The sample consisted of 129 university students, of which 65 underwent a yoga training for 12 weeks and a control group that did not carry out any type of intervention. The primary outcome was stress, which was collected through The Perceived Stress Scale (PSS). The secondary outcomes were emotional wellbeing which was measured through the Warwick-Edinburgh Mental Wellbeing Scale (WEMWBS), and anxiety through State-Trait Anxiety Inventory (STAI). All variables were measured before and after the intervention. Results: Participants in the experimental group showed statistically significant improvements in the primary outcome perceived stress (Cohen's d = 0.44) and the secondary outcomes emotional wellbeing (Cohen's d = 0.47), and both state anxiety (Cohen's d = 0.38) and trait anxiety (Cohen's d = 0.80) compared to the control group that did not carry out any type of physical training. Conclusion: This study demonstrated that a 12-week yoga intervention can significantly reduce perceived stress and anxiety, and improve emotional wellbeing in university students. Initially, the experimental group (EG) reported higher levels of stress and anxiety than the control group (CG), but after the intervention, the EG experienced significant improvements compared to the CG.

Effects of mindfulness-based cognitive therapy on older adults with sleep disorders: a systematic review and meta-analysis.

Objective: This systematic review and meta-analysis was conducted to analyze the effectiveness of a mindfulness-based program on sleep quality in healthy non-institutionalized older people. Methods: This study was conducted following the PRISMA (Preferred Reporting Items For Systematic Reviews And Meta-Analyses) guidelines. The search was conducted during May and June 2023 using four databases: Pubmed, Scopus, Web of Science, and CINAHL. Different keywords combined with Boolean operators were used. Only 10 articles of the initial 177 were included. In the study, the standardized mean difference (SMD) was used along with a 95% confidence interval to measure the effect. Heterogeneity among the studies, assessed using Cochran's Q-test and the I2 statistic was found to be low, leading to the use of a fixed-effects model in the analysis. The effect size was expressed as Hedge'g. Furthermore, a subgroup analysis was conducted, taking into account the various tools used to assess sleep conditions. Results: Mindfulness was found to reduce poor sleep quality in people with both long-term and short-term sleep disorders. Weighting effect model Hedge'g = -0.344 with a 95% confidence interval ranging from -0.425 to -0.263. In all cases, statistically significant results were observed, as well as moderate and negative effect sizes according to the Hedge's g index: -0.326 for Insomnia Severity Index (ISI), -0.343 for Pittsburgh Sleep Quality Index (PSQI), and -0.28 for Sleep Onset Latency (SOL). Conclusion: This systematic review and meta-analysis found that mindfulness can be used to remedy poor sleep quality in older people, so it could be a viable treatment option for insomnia or other problems related to poor sleep quality in this population.

Effectiveness of Therapeutic Education in Patients with Cancer Pain: Systematic Review and Meta-Analysis.

(1) Objective: To review the existing evidence on pain education in patients with pain derived from an oncological process. (2) Methods: A systematic review was conducted using the databases Pubmed, Web of Science, PEDro, and Scopus. The selected studies had to incorporate instruction about the neurophysiology of pain into their educational program. The target population was cancer patients who had suffered pain for at least one month. The methodological quality of the articles collected was assessed using the PEDro scale. (3) Results: Some 698 studies were initially identified, of which 12 were included in this review. Four different models of pain education programs were found in the studies' interventions. Pain intensity, pain experience, quality of life, pain tolerance, and catastrophism were the variables that appeared most frequently. (4) Conclusions: This review demonstrates that pain education in patients with cancer pain may produce effects such as decreased pain intensity and catastrophism. Knowledge about pain also seems to increase. However, no benefit was reported for patients' overall quality of life. Therefore, more research is needed to clarify the effects of these interventions on the oncology population.
