Effect of serum 25‐hydroxyvitamin D3 on insulin resistance and β‐cell function in newly diagnosed type 2 diabetes patients

Aims/Introduction

To evaluate serum 25‐hydroxyvitamin D₃ (25(OH)D₃) in newly diagnosed type 2 diabetes patients and to explore the associations of 25(OH)D₃ with insulin resistance and β‐cell function.

Materials and Methods

A total of 97 newly diagnosed type 2 diabetes patients and 69 healthy controls were recruited. Serum 25(OH)D₃ was determined using high‐pressure liquid chromatography. Insulin resistance was measured using a homeostasis model assessment of insulin resistance (HOMA‐IR). β‐Cell function was determined using the HOMA β‐cell function index (HOMA‐β), early‐phase insulin secretion index (ΔI30/ΔG30) and area under the insulin curve (AUCins). Correlation analysis was carried out using Pearson''s correlation and multiple stepwise regression analysis.

Results

Serum 25(OH)D₃ was much lower in patients with newly diagnosed type 2 diabetes (t = −13.00, P < 0.01), and the prevalence of hypovitaminosis 25(OH)D₃ was 62.9% (61/97) in diabetic patients. Among the diabetic patients, patients with hypovitaminosis 25(OH)D₃ showed higher glycosylated hemoglobin and AUCglu (P < 0.01) as well as lower HOMA‐β, ΔI30/ΔG30 and AUCins. Serum 25(OH)D₃ was independently positively correlated with ΔI30/ΔG30 and AUCins (P < 0.05), but was not significantly correlated with either HOMA‐IR or HOMA‐β. Only triglycerides, glycosylated hemoglobin and ΔI30/ΔG30 emerged as independent factors associated with serum 25(OH)D₃ in both diabetes patients and the health control group.

Conclusions

The present results further showed a low serum 25(OH)D₃ concentration in patients with newly diagnosed type 2 diabetes. 25(OH)D₃ deficiency is associated with disturbances in glucose metabolism and lipid metabolism. Serum 25(OH)D₃ is not correlated with basal insulin resistance or β‐cell function, but is significantly positively correlated with glucose‐stimulated insulin secretion and β‐cell function.     

Transition of newly graduated nurses in China: An evaluation study

The work adaptation of newly graduated nurses exerts a vital impact on their career developments. It is of great significance to guide newly graduated nurses to get acclimatized to the student-to-nurse transition. This study aimed to investigate the work adaptability disorder from the perspective of the organizational socialization and explore the potential factors of work adaptability disorder of newly graduated nurses. A cross-sectional study was performed. Convenience sampling was adopted to recruit 206 newly graduated nurses at four tertiary hospitals in China. The Work Adaptability Disorder Scale, the Transition Shock of Newly Graduated Nurses Scale, and the Organizational Socialization Questionnaire were utilized to measure the work adaptability disorder. The results showed the level of work adaptability disorder was mediocre among newly graduated nurses in China. The variables of gender, education, only child, family residence, transition shock, and organizational socialization could serve as predictors of work adaptability. Our research showed countermeasure of improving organizational socialization and relieving transition shock should be added to the training program of newly graduated nurses with purpose of promoting their adaptation.     

Mechanism and prevention of enlargement or new development of aneurysm following treatment by clipping or coiling

Abstract

The mechanisms of cerebral aneurysm recurrence and enlargement were Investigated in 11 patients: two with dissecting aneurysms, six with fully grown aneurysms after neck clipping, one with enlarged aneurysm after dome clipping, and two with enlarged aneurysm due to recanalization after GDC coil embolization. We concluded that it is fundamentally important to ensure complete attachment of the internal elastic lamina around the aneurysm neck by precise neck clipping and effective embolization, with accurate positioning of remaining internal elastic lamina.

海南省三亚市2010—2021年新报告HIV/AIDS晚发现情况及影响因素分析

目的 了解三亚市2010—2021年艾滋病病毒（HIV）感染者/艾滋病（AIDS）患者（简称HIV/AIDS）晚发现情况及影响因素,为降低晚发现比例提供依据。方法 从中国疾病预防控制信息系统中收集三亚市2010—2021年新报告的HIV/AIDS信息,依据中国疾病预防控制中心2014年提出的5类晚发现判断标准识别晚发现者,以是否为晚发现者为因变量,人口学信息为自变量,运用二元Logistic逐步回归模型分析HIV/AIDS发生晚发现的影响因素。结果 三亚市2010—2021年新报告HIV/AIDS 710例,晚发现比例为33.4%（237例）;第1~5类晚发现构成比分别是0.8%、59.1%、10.1%、17.3%和12.7%。2010—2021年晚发现比例由95.5%降至22.4%,呈下降趋势（χ²_趋势=34.777,P<0.05）。多因素分析结果,民族、文化程度、样本来源和确证年份是三亚市HIV/AIDS晚发现的影响因素,黎族HIV/AIDS晚发现比例为56.8%,晚发现风险高于汉族（OR=2.253,95%CI=1.361~3.670）;初中及以下文化程度HIV/AIDS晚发现比例为55.5%,晚发现风险是高中及以上者的1.722倍（95%CI=1.072~2.765）;样本来源于医疗机构和检测咨询者晚发现比例分别为63.1%和45.5%,晚发现风险均高于来源于MSM人群者（OR=5.564,95%CI=3.278~9.444;OR=2.204,95%CI=1.239~3.923）;与2018—2021年相比,2010—2013年确证者风险较高（OR=2.246,95%CI=1.311~4.488）。结论 三亚市HIV/AIDS晚发现形势不容忽视,尤其是来源于咨询检测和医疗机构的HIV/AIDS,应加强检测力度,提高人群主动检测意识。
