An Analysis of the Effects of Predictive Early Nutritional Care Interventions in Patients Undergoing Maintenance Haemodialysis.

Objective: To study the effect of predictive early nutritional care intervention on gastrointestinal function, Subjective global nutritional assessment (SGA) score, serum albumin (ALB) and high-sensitivity C-reactive protein (hs CRP), quality of life and quality of sleep in patients on maintenance haemodialysis. Methods: A total of 90 cases of maintenance hemodialysis patients in our hospital were collected from March 2020 and randomly divided into two groups of 45 cases each. The control group was cared for according to routine procedures. The study group added predictive early nutritional care intervention to this control group, i.e., nutritional personalized care was adjusted according to the patient's own disease, adherence, and comorbidities. The nursing effects, improvement of gastrointestinal function, and serum indexes when the two groups were compared. Results: Before the intervention, there was no difference between the two groups regarding the improvement of gastrointestinal function, pg-sga score, or serum indexes (P > .05). After the intervention, the gastrointestinal function, pg-sga score and serum indexes in the two groups were improved, and the calorie and protein intake, the total effective rate of gastrointestinal function improvement, ALB level and quality of life score in the control group were significantly lower than those in the study group; BMI, AC, and TSF were significantly higher compared with study group; The level of hs CRP and sleep quality score in the study group were smaller than those in the study group (P < .05). Conclusion: Through predictive early nutritional care intervention, maintenance hemodialysis patients can increase food intake and improve protein and calorie intake. In turn, it effectively improves gastrointestinal function, malnutrition and microinflammation, and improves life and sleep, which is worthy of clinical promotion.

Effects of physical activity interventions on executive function in older adults with dementia: A meta-analysis of randomized controlled trials.

BACKGROUND: To date quantitative meta-analysis with large samples to investigate the effects and potential moderators of physical activity (PA) on executive function (EF) in older adults with dementia is insufficient. Therefore, we conducted this meta-analysis. DESIGN: Meta-analysis of randomized controlled trials (RCTs). PARTICIPANTS: Old people with Alzheimer's disease (AD) or related dementia of varying types and severity as the primary diagnosis. METHODS: PubMed, Web of Science, the Cochrane Library and Embase databases were searched for relevant studies published from 01 January, 2010 to 01 March, 2022. The results of executive function were reported in all RCTs. Random-effects meta-analysis was used to calculate the size of effects. Subgroup analyses of three moderators (including the specific sub-domains of EF, exercise prescription variables, and sample characteristics) were performed. RESULTS: Eighteen RCTs were included with a combined sample size of 1366. Overall, PA interventions improved overall EF (standardized mean difference [SMD]=0.23, 95% confidence interval [CI] 0.05 to 0.41, p<0.05). The EF sub-domain "planning" was significant moderator (SMD=0.31, 95%CI 0.11 to 1.51, p<0.01), but inhibitory control, working memory and cognitive flexibility were not significant. Regarding exercise prescription variables, type of resistance training; moderate intensity; total duration ≤24 weeks and short (once or twice a week) frequency improved overall EF performance. Session length may be a moderator. Regarding sample characteristics, old-old, AD and both dementia and AD had significant benefits. CONCLUSIONS AND IMPLICATIONS: EF in older adults with AD or related dementia benefited from physical activity, and the benefit was affected by the type, intensity, total duration, frequency of exercise. Physical activity can be an alternative intervention in aging patients with dementia, to improve EF performance or prevent or EF decline.

Sandwich teaching improved students' critical thinking, self-learning ability, and course experience in the Community Nursing Course: A quasi-experimental study.

The youngest generation of students prefers a more active learning style. Sandwich teaching may suit their learning style by alternating between active individual learning and passive collective learning. Sandwich teaching has been rarely applied to the Community Nursing Course for nursing students, and its teaching effects on this course remain unclear. This study applied Sandwich teaching to the Community Nursing Course for Chinese nursing undergraduates and investigated its effects on students' critical thinking, self-learning ability, course experience, and academic performance. This is a quasi-experimental study with 72 Chinese nursing undergraduates. Students receiving traditional teaching were enrolled in the control group (n = 36), and those who received Sandwich teaching were recruited into the experimental group (n = 36). Both groups received the 12-week, 90-min Community Nursing Course. Our main outcome variable, including students' critical thinking, self-learning ability, and course experience, was assessed by specific questionnaire. The paired t-tests were applied to compare the differences of the same group in the pre-test and the post-test, and the independent-sample t-tests were used to compare the differences between the two groups. We observed that nursing students' critical thinking ability and self-learning ability were significantly improved after receiving Sandwich teaching. Students' course experience of Sandwich teaching was significantly better than that of traditional teaching. The final exam score in the experimental group was not significantly higher than that in the control group. These results suggest that Sandwich teaching in Community Nursing Course improved Chinese nursing undergraduates' critical thinking, self-learning ability, and course experience, but failed in improving academic performance.

Effects of ARCS model-based motivational teaching strategies in community nursing: A mixed-methods intervention study.

BACKGROUND: Learning motivation is important for students to master professional knowledge. Teaching strategies play a role in promoting learning motivation and cultivating nursing students' critical thinking. OBJECTIVES: To apply the Attention, Relevance, Confidence, and Satisfaction (ARCS) model-based motivational teaching strategies in a community nursing course and evaluate the effects on learning motivation, critical thinking, and self-learning ability. DESIGN: A mixed-methods study using a quasi-experimental design and descriptive qualitative analysis. METHODS: Thirty-six third-year nursing students were divided into two groups. The experimental group was exposed to motivational teaching strategies based on the ARCS model in the 12-week community nursing course. The control group received traditional teaching. Students' critical thinking, self-learning ability and academic performance were quantitatively assessed, with t-tests performed to compare learning outcomes. Qualitative outcomes were evaluated through semi-structured interviews, analyzed by using thematic analysis. RESULTS: Students in the experimental group demonstrated significantly greater critical thinking and higher test scores than those in the control group. The self-learning ability and learning motivation of the students exposed to ARCS were also strengthened, and students reported high levels of satisfaction with the motivational teaching strategies. CONCLUSIONS: Applying the ARCS model-based motivational teaching strategies in community nursing courses is feasible and associated with improved learning motivation and outcomes among Chinese nursing undergraduates.
