To analyze the characteristics of pulmonary nodules (PNs) and related influencing factors in patients with type 2 diabetes mellitus (T2DM). Retrospectively analyzed the clinical and biochemical characteristics of 224 patients with PNs and 488 patients with non-PNs in patients with T2DM, and compared the clinical data of 72 patients with large nodules (≥ 5 mm) and 152 patients with small nodules (< 5 mm) in the pulmonary nodules (PNs) group. Compared to the non-PNs group, the PNs Patients in the group had a longer duration of diabetes, higher age, serum creatinine (SCR), blood urea nitrogen (BUN) and the lower albumin (ALB) and body mass index (BMI); women, diabetic retinopathy (DR), diabetic peripheral neuropathy (DPN), and estimated glomerular filtration rate (eGFR) < 60 ml/min1.73m2 were more represented in the PNs group; there were fewer patients with overweight in the PNs group. Age and eGFR < 60 ml/min/1.73m2 were independent risk factors for PNs in patients with T2DM, and overweight was associated with a reduced risk of PNs. Compared with the small nodule group, patients in the large nodule group had higher fasting blood glucose (FBG) and lower fasting insulin (FINS); meanwhile, patients with decreased homeostasis model assessment-β (HOMA-β) and high smoking index (SI) were higher in the large nodule group; decreased HOMA-β and high SI were independent risk factors for large nodules. Age and eGFR < 60 ml/min/1.73m2 were independent risk factors for pulmonary nodules in patients with T2DM, and overweight may be a protective factor. Moreover, decreased islet B-cell function and smoking may contribute to the presence of PNs with a diameter of over 5 mm.
Visceral adiposity index (VAI) is a reliable indicator of visceral adiposity. However, no stu-dies have evaluated the association between VAI and DKD in US adults with diabetes. Theref-ore, this study aimed to explore the relationship between them and whether VAI is a good pr-edictor of DKD in US adults with diabetes. Our cross-sectional study included 2508 participan-ts with diabetes who were eligible for the National Health and Nutrition Examination Survey (NHANES) from 2007 to 2018. Univariate and multivariate logistic regression were used to an-alyze the association between VAI level and DKD. Three models were used to control for pot-ential confounding factors, and subgroup analysis was performed for further verification. A tot-al of 2508 diabetic patients were enrolled, of whom 945 (37.68%) were diagnosed with DKD. Overall, the VAI was 3.36 +/- 0.18 in the DKD group and 2.76 +/- 0.11 in the control group. VAI was positively correlated with DKD (OR = 1.050, 95% CI 1.049, 1.050) after fully adjusting for co-nfounding factors. Compared with participants in the lowest tertile of VAI, participants in the highest tertile of VAI had a significantly increased risk of DKD by 35.9% (OR = 1.359, 95% CI 1.355, 1.362). Through subgroup analysis, we found that VAI was positively correlated with the occurrence of DKD in all age subgroups, male(OR = 1.043, 95% CI 1.010, 1.080), participants wit-hout cardiovascular disease(OR = 1.038, 95% CI 1.011, 1.069), hypertension (OR = 1.054, 95% CI 1.021, 1.090), unmarried participants (OR = 1.153, 95% CI 1.036, 1.294), PIR < 1.30(OR = 1.049, 95% CI 1.010, 1.094), PIR >= 3 (OR = 1.085, 95% CI 1.021, 1.160), BMI >= 30 kg/m(2) (OR = 1.050, 95% CI 1.016, 1.091), former smokers (OR = 1.060, 95% CI 1.011, 1.117), never exercised (OR = 1.033, 95% CI 1.004, 1.067), non-Hispanic white population (OR = 1.055, 95% CI 1.010, 1.106) and non-Hipanic black population (OR = 1.129, 95% CI 1.033, 1.258). Our results suggest that elevated VAI levels are closely associated with the development of DKD in diabetic patients. VAI may be a simpl-e and cost-effective index to predict the occurrence of DKD. This needs to be verified in furt-her prospective investigations.
Abstract Objective:The gut microbiota was considered to be an important hidden "organ" of the human body, which was of great significance in maintaining the body's physiology and pathological regulation. Previous studies had found that the gut microbiota was closely related to various diseases, but there was no unified conclusion on the distribution characteristics of the gut microbiota in chronic kidney disease (CKD) and its relationship with the progression of CKD. In this study, we tried to investigate the profile and function of gut microbiota in CKD and its relationship with the progression of CKD. Methods: A total of 80 people were enrolled in this study. Twenty were healthy people, and 60 were CKD patients. The CKD patients were divided into three stages including stage 3, 4, and 5. We conducted taxonomic analyses in different groups. The distributions of phyla, classes, orders, families and genera in different groups and samples were investigated. We also evaluated the correlations between clinical parameters and gut microbiota in 60 CKD patients. Results:The gut microbiota in the healthy group and CKD group had 2351 operational taxonomic units (OTUs) in total. The healthy group had 1076 OTUs, and the CKD group had 2259 OTUs. The diversity of gut microbiota in the stage 3 CKD group was smaller than that in the other groups. Bacteroides was positively correlated with serum creatinine (Scr) and serum cholesterol, while was negatively correlated with albumin (ALB), haemoglobin, and estimated glomerular filtration rate (eGFR). Blautia was positively correlated with Scr, blood urea nitrogen (BUN), 24-hour urine protein (24-h UTP), and serum cholesterol, while was negatively correlated with haemoglobin and eGFR。Bifidobacterium was positively correlated with eGFR, while was negatively correlated with Scr and BUN. Prevotella was negatively correlated with BUN, while was positively correlated with haemoglobin. Megamonas was negatively correlated with BUN, while was positively correlated with haemoglobin and eGFR. Subdoligranulum was negatively correlated with UA. Parabacteroides and megasphaera were positively correlated with serum cholesterol. Klebsiella was negatively correlated with haemoglobin. Conclusions:The gut microbiota might be one of the important pathological mechanisms underlying the development and progression of CKD. The changes of diversity in gut microbiota were associated with disease progression. Some kinds of gut microbiota including bacteroides, blautia, parabacteroides, megasphaera and klebsiella might be detrimental factors in CKD, while other kinds of gut microbiota including bifidobacterium, prevotella, megamonas and subdoligranulum might be beneficial factors in CKD.
