Objective: To explore the relationship between muscle fat deposition , muscle iron deposition , and glu- cose metabolism in elderly obese patients . Methods: Elderly obese patients who visited the outpatient clinic were selected . Oral glucose tolerance tests were performed . Muscle fat and iron deposition in the abdominal wall and pa- raspinal muscles at the L3 vertebra level were quantified using the Dixon technique based on nuclear magnetic reso- nance . Results: A total of 140 elderly obese patients were included , among which 46 were newly diagnosed with type 2 diabetes mellitus (T2DM) , 44 had impaired glucose tolerance (IGR) , and 50 had normal glucose tolerance (NGT) . Compared to NGT and IGR groups , patients with T2DM had significantly increased muscle fat deposition , iron deposition , and visceral fat , while subcutaneous fat was significantly reduced (P < 0. 05) . After adjusting for confounding factors using multivariate logistic regression , muscle fat deposition was identified as an independent risk factor for glucose metabolism disorders : patients with muscle fat≥42. 2% had a 2. 9 times risk of glucose me- tabolism abnormalities compared to those with muscle fat < 42. 2% . Conclusion With the occurrence of glucose metabolism disorders , muscle fat and iron deposition gradually increase in elderly obese patients . Muscle fat depo- sition is an independent risk factor for predicting glucose metabolism abnormalities in elderly obese patients .

Objective To investigate the predictive value of dynamic monitoring of transcutaneous oxygen partial pressure [p_tc(O₂)], transcutaneous carbon dioxide partial pressure [p_tc(CO₂)], serum amyloid A (SAA), and interleukin-6 (IL-6) levels in predicting bronchopulmonary dysplasia (BPD) in neonates with neonatal respiratory distress syndrome (NRDS). Methods A total of 240 NRDS patients were selected as the research subjects and divided into BPD group (108 cases) and non-BPD group (132 cases) based on whether BPD occurred. The levels of p_tc(O₂), p_tc(CO₂), SAA, and IL-6 were compared between the two groups on the 1st, 7th, and 14th day after birth. Spearman correlation analysis was used to explore the correlation between each indicator and the degree of illness. The relative risk (RR) and 95% confidence interval (CI) were used to evaluate the impact of each indicator on BPD in NRDS patients. Receiver operating characteristic (ROC) curves and decision curve analysis were used to evaluate the predictive efficacy and clinical net benefit of each indicator for BPD. Results On the 1st day after birth, there were no statistically significant differences in p_tc(O₂), p_tc(CO₂), serum SAA, and IL-6 levels between the two groups (P>0.05). On the 7th and 14th day after birth, the p_tc(O₂) in the BPD group was lower than that in the non-BPD group, while the p_tc(CO₂) and serum SAA, IL-6 levels were higher than those in the non-BPD group (P < 0.05). Correlation analysis results showed that the degree of BPD in children was negatively correlated with p_tc(O₂) on the 7th day after birth (r=-0.724, P < 0.05), and positively correlated with p_tc(CO₂), SAA, and IL-6 on the 7th day after birth (r=0.635, 0.830, 0.715, P < 0.05). The degree of pulmonary dysfunction in children was negatively correlated with p_tc(O₂) on the 7th day after birth (r=-0.719, P < 0.05), and positively correlated with p_tc(CO₂), SAA, and IL-6 on the 7th day after birth (r=0.673, 0.756, 0.696, P < 0.05). On the 7th day after birth, the p_tc(O₂) of BPD patients was negatively correlated with SAA and IL-6 (r=-0.605, -0.623, P < 0.05), while p_tc(CO₂) was positively correlated with SAA and IL-6 (r=0.618, 0.650, P < 0.05). ROC curve showed that the combined prediction of p_tc(O₂), p_tc(CO₂), SAA, and IL-6 on the 7th day after birth for NRDS complicated with BPD was better than the individual prediction of the four indicators, with an area under the curve of 0.938 (95%CI, 0.899 to 0.965). The risk of BPD in high-expression of p_tc(CO₂), SAA, and IL-6 was 2.256, 1.668, and 1.667 times higher than that in low-expression, respectively. The risk of BPD in high-expression of p_tc(O₂) was 0.568 times higher than that in low-expression. The decision curve analysis showed that when the threshold value was within the range of 0.2 to 0.9, the combined model of p_tc(O₂), p_tc(CO₂), SAA, and IL-6 was superior to the individual prediction in predicting the net benefit rate of BPD in NRDS patients on the 7th day after birth. Conclusion The severity of NRDS complicated with BPD is closely related to p_tc(O₂), p_tc(CO₂), SAA, and IL-6, and the combined detection of the four indicators can help improve the predictive efficacy and net benefit rate of NRDS complicated with BPD.
