The prevalence, hospitalization outcomes and risk factors of euthyroid sick syndrome in patients with diabetic ketosis/ketoacidosis.

BACKGROUND: To investigate the prevalence of euthyroid sick syndrome (ESS) and to evaluate the outcomes and risk factors associated with ESS among hospitalized patients with diabetic ketosis (DK) or diabetic ketoacidosis (DKA). METHODS: Laboratory and clinical data of 396 adult hospitalized DK/DKA patients with or without ESS were collected and analyzed. Spearman linear analysis and multivariable logistic regression analyses were used to evaluate correlated factors of thyroid hormones and risk factors of ESS. RESULTS: Most of the individuals were diagnosed with type 2 diabetes (359/396, 90.7%). The prevalence of ESS was 57.8% (229/396). Patients in ESS group were older and had a longer course of diabetes. Levels of thyroid hormones, serum lipids, and parameters reflecting acidosis were significantly decreased in ESS group. The proportion of patients with infection, acute renal injury and DKA was significantly higher in ESS group than in control group, accompanied by longer hospitalization stay and higher hospitalization costs. Free triiodothyronine positively correlates with albumin, eGFR, parameters reflecting acidosis and lipid profiles (All P < 0.001), and negatively correlates with age, onset age, 24-h urine albumin, hsCRP and WBC count (All P < 0.001). Hypoalbuminemia, low level of carbon dioxide combining power, high level of HbA1c and WBC, and co-infection are shown to be risk factors for ESS (OR = 0.866, 0.933, 1.112, 1.146, 1.929, respectively; All P < 0.05). CONCLUSIONS: The prevalence of ESS was high in adult DK/DKA patients. Patients with ESS had inferior clinical and socioeconomic outcomes. Early recognition and management of patients with ESS may be necessary to improve outcome.

Dietary Zinc Intake Affects the Association Between Dietary Vitamin A and Depression: A Cross-Sectional Study.

Introduction: Dietary vitamin A concentrations correlate with depression. Zinc has been reported to be associated with lower depression. In addition, zinc is an important cofactor in the activation of vitamin A. However, there are few studies investigating relationships between of dietary zinc intake, dietary vitamin A intake and depression. Materials and Methods: The data for this study came from the National Health and Nutrition Examination Survey (NHANES) from 2005 to 2018 and involved 70,190 participants. We stratified participants by recommended dietary zinc intake (recommended dietary zinc intake for women: 8 mg/day, recommended dietary zinc intake for men: 11 mg/day). We further assessed the association between vitamin A and depression in participants with low and high zinc intake (interaction test) using univariate logistic regression of intake participants. Result: In the female population we grouped the population into low and high zinc intake groups using the recommended dietary zinc intake of 8 (mg/day), with an increase in total vitamin A, the risk of depression was significantly lower in the low zinc intake group (OR: 0.85 95 CI: 0.76-0.96), while the risk of depression was increased in the high zinc intake group (OR: 1.05 95 CI: 0.95 to 1.17). Thus, in the female population, there was a significant interaction between insufficient vitamin an intake and depression (interaction likelihood ratio test of p = 0.011). In the male population we grouped the population by the recommended dietary zinc intake of 11(mg/day). Again, the population was divided into two groups with low and high zinc intake, however we did not find significant results for the interaction (p = 0.743 for the interaction likelihood ratio test). Conclusion: Our findings suggest that zinc intake may influence the relationship between dietary vitamin A and depression. Of course, our findings require further randomized controlled trials to enhance the credibility.

Hemoglobin A(1c) proportion, mortality rate, and risk factors for death in diabetic patients with severe hypoglycemia: a multicenter retrospective survey over ten years.

OBJECTIVE: To investigate the HbA(1c) proportion and mortality rate across diabetic patients with severe hypoglycemia and the risk factors for death. METHODS: All the diabetic patients with severe hypoglycemia were divided into HbA(1c)<6.5% group and HbA(1c)≥6.5% group. The proportion of HbA(1c), mortality rate and the risk factors for death were analyzed. Common causes for severe hypoglycemia were also analyzed. RESULTS: The percentages of HbA(1c) in the HbA(1c)<6.5% and HbA(1c)≥6.5% groups were 51.2% and 48.8%, respectively. The mortality rates were not significantly different between the 2 groups (5.3% vs. 5.1%, χ(2)=0.01, p=0.17). Binary logistic regression analysis revealed that in both groups, creatinine, aspartate aminotransferase, and uric acid levels were the risk factors for death. In the HbA(1c)<6.5% and HbA(1c)≥6.5% groups, 65.0% and 64.2% showed common causes of severe hypoglycemia, respectively. CONCLUSIONS: With respect to severe hypoglycemia, equal attention should be paid to patients with an HbA(1c) level of ≥6.5% and those with an HbA(1c) level of <6.5%. The mortality rate is approximately 5% in severe hypoglycemia no matter how the HbA(1c) level is. Creatinine, aspartate aminotransferase, and uric acid are the main risk factors in both groups. Two-thirds of severe hypoglycemia cases could be prevented.
