Use of the Omaha System nursing model on nutritional status outcomes in peritoneal dialysis patients.

OBJECTIVE: To construct and apply a risk screening and intervention system for malnutrition in peritoneal dialysis patients based on the Omaha System. MATERIALS AND METHODS: A total of 75 peritoneal dialysis patients were randomly divided into control (38 cases) and intervention group (37 cases). The control group received routine operation training and health education, and the intervention group implemented a nutritional management plan based on the Omaha System. The modified quantitative subjective comprehensive nutritional scale (MQSGA) score, kidney disease dietary compliance attitude (RAAQ) and behavior (RABQ) score, body mass index (BMI), serum albumin (ALB), prealbumin (PA), and hemoglobin (Hb) were observed. RESULTS: Before intervention, there was no significant difference in these indicators between the two groups (p > 0.05). After 6 months, the MQSGA score in the intervention group was significantly lower than that in the control group (p < 0.05). RAAQ score and RABQ score in the intervention group were higher than those in the control group and (p < 0.05), and the nutritional indicators in the intervention group, such as BMI, ALB, PA, and Hb, were higher than those in the control group (p < 0.05). CONCLUSION: A nutritional management plan based on the Omaha System can help improve the nutrition condition of peritoneal dialysis patients, and improve the dietary compliance of chronic kidney disease patients.

Association of serum iron metabolism with muscle mass and frailty in older adults: A cross-sectional study of community-dwelling older adults.

This study aimed to explore the correlation between serum ferritin and additional biomarkers associated with iron metabolism, as well as their connection to muscle atrophy and frailty in the community-dwelling middle-aged and elderly population. The study included 110 middle-aged and elderly participants. Participants were categorized into an iron accumulation group (31 cases) and a normal iron group (79 cases) based on the standard ferritin values for men and women. Based on the criteria of the Asian Working Group on Muscular Dystrophy, participants were classified into a sarcopenia group (31 cases) and a non-sarcopenia group (79 cases). Using the Fried frailty syndrome criteria, participants were categorized into non-frailty (7 cases), pre-frailty (50 cases), and frailty (53 cases) groups. We employed multiple linear regression, binary logistic regression, partial correlation analysis, and ordinal logistic regression to assess the associations between iron metabolism indices and the presence of muscle atrophy and frailty. Compared with the normal iron group, the iron overload group had significantly higher ferritin, weight loss, fatigue, slow gait, and frailty scores (P < .05). Among the 3 models we set, ferritin was not significantly correlated with muscle mass in models 1 and 3 (P > .05), ferritin was positively correlated with muscle mass in model 2 (Pmodel2 = .048), but Transferrin saturation was positively correlated with muscle mass in all 3 models (Pmodel1 = .047, Pmodel2 = .026, Pmodel3 = .024). Ferritin, body mass index and iron overload were the influencing factors of sarcopenia (Pferritin = .027, PBMI < .001, Piron overload = .028). Ferritin was positively correlated with weight loss, fatigue, slow gait, frailty score, and frailty grade (P < .05). Age, gender and ferritin were the influencing factors of frailty classification (P < .05). Disrupted iron metabolism can lead to decreased muscle mass and function among the middle-aged and elderly, increasing frailty risk. It's crucial to prioritize community-based frailty screening and prevention, focusing on iron utilization as well as storage, since accelerating the body's iron metabolism cycle might influence muscle health more significantly than iron reserves.

Implementation of Evidence in Preventing Postoperative Sore Throat of Patients Undergoing General Anesthesia Intubation Using the i-PARIHS Framework.

Objective: The aim of the study was to assess the effectiveness of the implementation of the best evidence in preventing postoperative sore throat in patients undergoing general anesthesia intubation. Methods: The related topics of the postoperative sore throat of patients undergoing general anesthesia intubation were systematically searched in the database and evaluated using the Integrated Promoting Action on Research Implementation in Health Services (i-PARIHS) framework. Combined with clinical needs and evidence-based professional judgment, 20 pieces of evidence and 6 examination standards on the management process and evidence implementation plan for the prevention of postoperative sore throat in patients with general anesthesia intubation are summarized, implementing the best evidence into clinical practice in anesthesiology, general surgery, orthopedics, thoracic surgery, and gynecology. Results: Nurses' knowledge scores and evidence compliance significantly improved after the implementation of the best evidence (P < 0.05); the incidence of the postoperative sore throat in patients undergoing general anesthesia intubation decreased from 41.7% to 28.1%. Conclusion: The i-PARIHS framework effectively prevents postoperative sore throat in patients, providing an effective case for translating evidence into practice based on the i-PARIHS framework.

Reduced circulating oxytocin and High-Molecular-Weight adiponectin are risk factors for metabolic syndrome.

The neurohypophysial hormone, oxytocin, is involved in the regulation of energy metabolism. Adiponectin (APN) is an adipose tissue-specific serum protein that inversely associates with metabolic syndrome (MetS). High-molecular-weight adiponectin (HMW APN) is considered the active form. In the present study, we aimed to determine the relationships of oxytocin and HMW APN to MetS and investigate whether or not the combination of oxytocin and HMW APN is associated with further metabolic abnormalities compared to each of them alone. A total of 170 subjects (75 with MetS and 95 non-MetS) were enrolled. Anthropometric parameters, oral glucose tolerance test (OGTT), blood lipids, hs-CRP, oxytocin and HMW APN levels were measured. Compared with non-MetS subjects, serum oxytocin and HMW APN levels were significantly lower in subjects with MetS (P<0.01). We then classified the subjects into three groups: high oxytocin and high HMW APN levels (high score group), low oxytocin and low HMW APN levels (low score group) and others. Participants in low score group showed the worst metabolic profiles and were more likely to have MetS compared to the other two group. In Spearman rank correlation coefficient, the classification by the combination of oxytocin and HMW APN was significantly correlated with a larger number of metabolic risk factors compared with classification by each of them alone. Individuals with low circulating oxytocin levels coupled with low HMW APN levels were at significantly increased risk of MetS. The combination of both markers would be useful for identifying MetS high risk patients.
