Purpose:Thyroid hormones (THs) significantly affect the cardiovascular system. N-terminal pro-B-type natriuretic peptide (NT-proBNP) is a useful biomarker for diagnosing, evaluating, and predicting outcomes in heart failure (HF). This comprehensive review and meta-analysis aimed to investigate the effects of thyroid dysfunction (hypothyroidism and hyperthyroidism) on NT-proBNP levels. Methods:Two investigators independently searched PubMed, Embase, Cochrane Library, and Web of Science databases for studies published from inception to July 31, 2022, without any restrictions on language. Results:21 studies were included. In participants without HF, NT-proBNP levels may be elevated in those with overt hyperthyroidism (standardized mean difference [SMD] 2.38, 95% confidence interval [CI]:1.0-3.76). Notably, among patients with preexisting HF, significantly higher NT-proBNP levels were found in patients with overt hyperthyroidism, overt hypothyroidism, or subclinical hypothyroidism than in euthyroid subjects (SMD [95%CI] = 0.31[0.01, 0.62], 0.32[0.08, 0.56], and 0.33[0.21, 0.46], respectively). Seven trials compared NT-proBNP levels in patients with thyroid dysfunction before and after therapy, and significant drops in NT-proBNP levels were observed in patients with hyperthyroidism (SMD [95%CI] = -1.53[-2.50, -0.55]) upon achieving a euthyroid state. In contrast, increased NT-proBNP levels were observed in hypothyroid patients after treatment (SMD [95%CI] = 1.07[0.28, 1.85]). Conclusion:Thyroid dysfunction can significantly affect NT-proBNP levels, which may change upon achieving a euthyroid state. Notably, the effect of thyroid dysfunction on cardiac function may depend on the underlying cardiac status. Thus, timely recognition and effective treatment of cardiac symptoms in patients with thyroid dysfunction are mandatory because the prognosis of HF may be improved with appropriate treatment of thyroid dysfunction.

帕金森病(parkinson's disease,PD)是第二大常见的神经退行性病变,主要表现为运动迟缓、肌强直、静止性震颤等运动症状,以及痴呆、抑郁、社交恐惧等非运动症状.2型糖尿病(diabetes mellitus type 2,T2DM)是最常见的慢性病之一,其特征是长期胰岛素抵抗(insulin resistance,IR)和胰岛素分泌缺陷.PD和T2DM有共同发病机制,如IR、糖基化终末产物及甲基乙二醛大量累积、氧化应激和线粒体功能障碍等,T2DM患者发生PD的风险增加.治疗T2DM的药物,如二甲双胍、胰岛素增敏剂等具有神经修复和保护功能,有可能成为治疗帕金森的潜在药物.同时,治疗PD的药物,如溴隐亭、左旋多巴也会影响糖代谢及胰岛素分泌.本文旨在概述PD与T2DM的相关机制,同时总结两者的潜在治疗方法.
Although nonalcoholic fatty liver disease (NAFLD) commonly occurs in overweight or obese individuals, it is increasingly being identified in the lean population. The association between lean and an increased risk of all-cause mortality among patients with NAFLD remains controversial. We aimed to perform a systematic review and meta-analysis of the literature to evaluate this association and compare the long-term outcomes of lean NAFLD patients and non-lean NAFLD patients. For this systematic review and meta-analysis, we searched PubMed, Embase, Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI), Wan Fang, and Chinese Biomedical Literature Database (CBM) from inception to October 15, 2021, for relevant original research articles without any language restrictions. Our primary outcome was to compare the all-cause mortality in lean NAFLD patients and non-lean NAFLD patients by qualitative synthesis. Relative risks (RRs) and corresponding 95
