The occult pulmonary infection is the most common complications in elderly patients with type 2 diabetes mellitus (T2DM). Since its etiological characteristics has not been clarified, infection control remains a serious problem for public health. To investigate the prevalence and clinical significance of occult pulmonary infection in elderly T2DM patients, in this study, 573 elderly patients cochallenged with T2DM and community-acquired pulmonary infection from January 2018 to December 2020 were selected in the hospitals and divided into occult pneumonia group (OP, n = 249 ) and nonoccult pneumonia group (NOP, n = 324 ) according to the nature of infection. Clinical medical records were analyzed retrospectively to summarize the infection characteristics of elderly diabetics with occult pneumonia. The prevalence of the cases (278/324, 85.8%) in NOP group was not higher than that in OP group (206/249, 82.7%; P > 0.05 ). Also, there was not significant difference in the distribution of isolated pathogens among the positive patients. The length of hospitalization and mortality of OP patients were significantly higher than those NOP patients. Multivariate logistic regression showed that advanced age, comorbidities, hypothyroidism, senile dementia, and prolonged bed rest were independent risk factors for occult pneumonia in elderly diabetic patients. Therefore, the results demonstrated that the pulmonary infection in elderly patients with diabetes mellitus is often occult. Gram-negative bacteria are the predominant pathogens and cause poor prognosis. Advanced age, comorbidities (senile dementia, hypothyroidism), and prolonged bed rest are the independent risk factors for occult pneumonia.

Objectives. As a screening index of diabetic kidney disease (DKD), urinary albumin/creatine ratio (UACR) is commonly used. However, approximately 23.3%-56.6% of DKD patients with estimated glomerular filtration rate eGFR<60 ml/min per 1.73 m2 are normoalbuminuric. Thus, urinary biomarkers of nonalbuminuric renal insufficiency in type 2 diabetes mellitus (T2DM) patients are urgently needed. Methods. This cross-sectional study enrolled 209 T2DM patients with normoalbuminuria whose diabetes duration was more than 5 years. The patients were classified into two groups, NO-CKD (eGFR≥60 ml/min per 1.73 m2, n=165) and NA-DKD (eGFR<60 ml/min per 1.73 m2, n=44). Levels of urinary neutrophil gelatinase-associated lipocalin (NGAL), retinol-binding protein (RBP), plasminogen activator inhibitor-1 (PAI-1), vascular cell adhesion molecule-1 (VCAM-1), and E-cadherin were detected, and their correlations with eGFR, plasma TNF-α, IL-6, endothelin-1 (ET-1), and 8-hydroxydeoxyguanosine (8-OHdG) were assessed. Results. Among patients with renal insufficiency, 26.0% was normoalbuminuric. Compared to the NO-CKD group, the NA-DKD group was older with lower hemoglobin (HB) levels and higher systolic blood pressure (SBP), plasma TNF-α, IL-6, and 8-OHdG levels. Logistic regression analysis suggested that age, TNF-α, and 8-OHdG were independent risk factors for nonalbuminuric renal insufficiency. Compared to the NO-CKD group, the NA-DKD group exhibited significant increases in urinary NGAL and RBP levels but not PAI-1, VCAM-1, and E-cadherin. Urinary NGAL and RBP both correlated negatively with eGFR and positively with plasma IL-6 and 8-OHdG. Multiple linear regression indicated NGAL (β=−0.287, p=0.008) and RBP (β=−44.545, p<0.001) were independently correlated with eGFR. Conclusion. Age, plasma TNF-α, and 8-OHdG are independent risk factors for renal insufficiency in T2DM patients with normoalbuminuria. Urinary NGAL and RBP can serve as noninvasive biomarkers of normoalbuminuric renal insufficiency in T2DM.

It would be important to predict type 2 diabetes mellitus (T2DM) and diabetic nephropathy (DN). This study was aimed at evaluating the predicting significance of hemostatic parameters for T2DM and DN. Plasma coagulation and hematologic parameters before treatment were measured in 297 T2DM patients. The risk factors and their predicting power were evaluated. T2DM patients without complications exhibited significantly different activated partial thromboplastin time (aPTT), platelet (PLT), and D-dimer (D-D) levels compared with controls (P<0.01). Fibrinogen (FIB), PLT, and D-D increased in DN patients compared with those without complications (P<0.001). Both aPTT and PLT were the independent risk factors for T2DM (OR: 1.320 and 1.211, P<0.01, resp.), and FIB and PLT were the independent risk factors for DN (OR: 1.611 and 1.194, P<0.01, resp.). The area under ROC curve (AUC) of aPTT and PLT was 0.592 and 0.647, respectively, with low sensitivity in predicting T2DM. AUC of FIB was 0.874 with high sensitivity (85%) and specificity (76%) for DN, and that of PLT was 0.564, with sensitivity (60%) and specificity (89%) based on the cutoff values of 3.15 g/L and 245 × 109/L, respectively. This study suggests that hemostatic parameters have a low predicting value for T2DM, whereas fibrinogen is a powerful predictor for DN.

Abstract Objective Marginal ulcer (MU) is a serious complication after Roux-en-Y gastric bypass (RYGB) procedures. This study reports the incidence, risk factors and treatment outcomes of symptomatic and incidentally, at routine endoscopy diagnosed, MU. Methods All patients undergoing RYGB procedures between 2013 and 2018 at a single center were included. Upper endoscopy was performed in case of symptoms and/or routinely 2 and 5 years postoperatively. Results 568 patients (83.3% female) underwent RYGB procedure with a median age of 40 years and median initial body mass index of 41 kg/m2. Median time to follow-up was 2.99 years. Routine 2- and 5-year upper endoscopy was performed in 256 (55.3%) and 65 (38.0%) eligible patients, respectively. In 86 (15.1%) patients, MU was diagnosed at a median time of 14.2 months (4.58 – 26.2) postoperatively and 24.4% of patients with MU were asymptomatic. 76.7% of MUs were located on the side of the Roux-limb. 88.4% of MUs were treated conservatively; re-operation was necessary in 10 (11.6%) patients. Smoking and type 2 diabetes mellitus were the only independent risk factors for MU development in multivariate analysis with a hazard ratio of 2.65 and 1.18 (HbA1c per unit &gt;6.0), respectively. Conclusion MU is a common complication after gastric bypass surgery with 25% of patients being asymptomatic. Follow-up routine endoscopy is recommended for early MU detection and subsequent accurate therapy, especially in patients with the independent risk factors smoking and type 2 diabetes mellitus.
