Objective:To analyze the efficacy of nutrition intervention combined with rehabilitation exercise in elderly patients with chronic heart failure (CHF) complicated by sarcopenia.Methods:In this randomized controlled trial, seventy CHF patients with sarcopenia, aged 80 years or older, who had received standard CHF medication treatment and had stable conditions with preserved ejection fraction (HFpEF) from June 2021 to October 2022 at the China-Japan Friendship Hospital outpatient clinic were continuously selected. The patients were randomly divided into a test group ( n=35) and a control group ( n=35) using a random number table. The test group continued the original heart failure medication treatment, and on the basis of daily meal, supplemented with whey protein powder [37 g per serving (including 16.2 g of whey protein, 145 kcal), twice a day]; they were given resistance exercise primarily focused on resistance training (5 sets of exercises, progressively increasing to 3 days per week, twice a day, 5 sets per session, 20 repetitions per set). The control group maintained the original heart failure medication treatment plan and lifestyle. The body mass index, appendicular skeletal muscle mass index (ASMI), grip strength, Five-Times-Sit-to-Stand Test, 6-meter walking speed, 6-minute walk test, brain natriuretic peptide (BNP), left ventricular ejection fraction, ratio of early mitral flow peak velocity to early mitral annulus diastolic peak velocity (E/e′), serum albumin, hemoglobin, and serum creatinine were compared between the two groups before and after 3 months of intervention using t-tests and chi-square tests to analyze the efficacy of nutrition intervention combined with rehabilitation exercise in elderly patients with CHF complicated by sarcopenia. Results:Among the 70 patients, there were 42 males and 28 females. There was no significant difference in baseline data between the test group and the control group (all P>0.05). After 3 months of intervention, ASMI, grip strength and 6 min walking distance in the test group were all significantly higher than those in the control group [(6.43±1.07) vs (6.09±0.86) kg/m 2, (27.75±2.13) vs (23.45±0.47) kg, (361.51±58.71) vs (273.50±69.85) m], and significantly higher than those before intervention [(5.99±1.45) kg/m 2, (23.55±9.64) kg, (273.50±69.86) m]. The time of Five-Times-Sit-to-Stand Test, BNP and E/e′ in the test group were both significantly lower than those in the control group [(11.20±2.09) vs (15.36±0.46) s, (278.80±58.69) vs (400.80±87.86) ng/L, (11.10±0.81) vs (14.66±1.90)], and significantly lower than those before intervention [(18.51±2.90) s, (407.50±122.74) ng/L and (14.00±1.15)]. There was no significant difference in remaining indicators between the two groups (all P>0.05). Conclusion:Nutritional intervention combined with rehabilitation exercise primarily focused on whey protein supplementation and resistance training can significantly improve limb muscle mass, muscle strength, muscle function, and cardiac function in elderly patients with CHF complicated by sarcopenia on the basis of heart failure medication treatment.

Objective:To conduct a statistical analysis on the condition of patients with pneumoconiosis complicated with chronic pulmonary heart disease based on the Tei index, and to establish a relevant prediction model.Methods:In March 2022, a retrospective analysis of 226 patients diagnosed with pneumoconiosis in the Department of Occupational Disease of Yantai Yantaishan Hospital from January 2016 to January 2022 was conducted. The patients with pneumoconiosis complicated by pulmonary heart disease were included in the pulmonary heart disease group and others were included in the non-pulmonary heart disease group. logistic regression analysis was used to screen out the relevant factors and establish a risk prediction model. Hosmer-Lemeshow test was applied to determine the goodness of fit of the model, and the receiver operating characteristic (ROC) area under the curve (AUC) was used to evaluate the predictive effect of the model.Results:Among the 226 patients with pneumoconiosis, 58 patients had chronic pulmonary heart disease, accounting for 25.7% of the surveyed population. The logistic analysis showed that the course of disease, pneumoconiosis stage and Tei index were influencing factors of pneumoconiosis complicated with pulmonary heart disease ( P<0.05). A risk prediction model for pneumoconiosis patients complicated with pulmonary heart disease was developed: Z=6.253 X1+1.265 X2+1.423 X3+9.264, in which X1 was the stage of pneumoconiosis, X2 was the course of disease, and X3 was the Tei index. Hosmer-Lemeshow test was used to evaluate the goodness of fit of the risk prediction model for pneumoconiosis patients complicated with pulmonary heart disease, the results indicated that the prediction model was in good agreement with the actual situation (χ 2=11.59, P=0.254). The diagnostic ability of the model was evaluated by the ROC curve, and the results showed that its AUC was 0.897, the sensitivity was 0.947, and the specificity was 0.784. Conclusion:The course of disease, pneumoconiosis stage and Tei index are the influencing factors of pneumoconiosis complicated with pulmonary heart disease. The model constructed based on these factors has a good prediction effect, which can provide a basis for the early detection and intervention of pneumoconiosis complicated with pulmonary heart disease.

Objective:To analyze the risk factors of bronchopulmonary dysplasia(BPD)in very preterm infants(VPI), and to provide scientific basis for the prevention and treatment of BPD in VPI.Methods:A prospective multicenter study was designed to collect the clinical data of VPI in department of neonatology of 28 hospitals in 7 regions from September 2019 to December 2020.According to the continuous oxygen dependence at 28 days after birth, VPI were divided into non BPD group and BPD group, and the risk factors of BPD in VPI were analyzed.Results:A total of 2 514 cases of VPI including 1 364 cases without BPD and 1 150 cases with BPD were enrolled.The incidence of BPD was 45.7%.The smaller the gestational age and weight, the higher the incidence of BPD( P<0.001). Compared with non BPD group, the average birth age, weight and cesarean section rate in BPD group were lower, and the incidence of male infants, small for gestational age and 5-minute apgar score≤7 were higher( P<0.01). In BPD group, the incidences of neonatal respiratory distress syndrome(NRDS), hemodynamically significant patent ductus arteriosus, retinopathy of prematurity, feeding intolerance, extrauterine growth restriction, grade Ⅲ~Ⅳ intracranial hemorrhage, anemia, early-onset and late-onset sepsis, nosocomial infection, parenteral nutrition-associated cholestasis were higher( P<0.05), the use of pulmonary surfactant(PS), postnatal hormone exposure, anemia and blood transfusion were also higher, and the time of invasive and non-invasive mechanical ventilation, oxygen use and total hospital stay were longer( P<0.001). The time of starting enteral nutrition, cumulative fasting days, days of reaching total enteral nutrition, days of continuous parenteral nutrition, days of reaching 110 kcal/(kg·d) total calorie, days of reaching 110 kcal/(kg·d) oral calorie were longer and the breastfeeding rate was lower in BPD group than those in non BPD group( P<0.001). The cumulative doses of amino acid and fat emulsion during the first week of hospitalization were higher in BPD group( P<0.001). Multivariate Logistic regression analysis showed that NRDS, invasive mechanical ventilation, age of reaching total enteral nutrition, anemia and blood transfusion were the independent risk factors for BPD in VPI, and older gestational age was the protective factor for BPD. Conclusion:Strengthening perinatal management, avoiding premature delivery and severe NRDS, shortening the time of invasive mechanical ventilation, paying attention to enteral nutrition management, reaching whole intestinal feeding as soon as possible, and strictly mastering the indications of blood transfusion are very important to reduce the incidence of BPD in VPI.
