Case Report: Transient Stress Hyperglycemia in the Patient With ST-Elevation Myocardial Infarction

Transient stress hyperglycemia in the setting of acute myocardial infarction is a frequent phenomenon. Its transient nature should not dissuade the clinician from management of elevated blood glucose in a patient after an ST-elevation myocardial infarction. This case presents an adult patient after an ST-elevation myocardial infarction with transient stress hyperglycemia and the evidence used to identify optimal pharmacologic management and secondary prevention.     

Modulators of platelet function in aging

Abstract

Platelets are small, anucleated effector cells that play an important role in linking the hemostatic and inflammatory processes in the body. Platelet function is known to be altered under various inflammatory conditions including aging. A gain in platelet function during aging can increase the risk of thrombotic events, such as stroke and acute myocardial infarction. Anti-platelet therapy is designed to reduce risk of serious cerebrovascular and cardiovascular events, but the adverse consequences of therapy, such as risk for bleeding increases with aging as well. Age-associated comorbidities such as obesity, diabetes, and hyperlipidemia also contribute to increased platelet activity and thus can enhance the risk of thrombosis. Therefore, identification of unique mechanisms of platelet dysfunction in aging and in age-associated comorbidities is warranted to design novel antiplatelet drugs. This review outlines some of the current areas of research on aging-related mechanisms of platelet hyperactivity and addresses the clinical urgency for designing anti-platelet therapies toward novel molecular targets in the aging population.     

儿童肥胖症的相关影响因素与控制对策分析及其对糖尿病发病情况的影响

目的 分析儿童肥胖症的相关影响因素与控制对策分析及其对糖尿病发病情况的影响,为制定针对儿童肥胖症的防控措施提供理论依据。方法 将2012年5月-2018年1月期间于沈阳市第五人民医院儿科进行体检的836名儿童作为研究对象,统计本组研究对象中肥胖症发生率,并调查所有研究对象性别、年龄、学校性质、生活习惯等因素与肥胖症发生率的相关性。将出现肥胖症的患儿作为观察组,将正常儿童作为对照组,对比两组对象空腹血糖、餐后2 h血糖(2 hPBG),空腹血糖受损(IFG)、葡萄糖耐量异常(IGT)以及糖尿病发生率的差异。结果 836名儿童中,89名存在肥胖症,231名儿童体重超重,516名儿童BMI正常,肥胖症发生率为10.65%;多因素Logistic回归分析结果显示,男性(OR＝6.415,95%CI:2.714~12.684,P=0.027)、年龄>10岁(OR＝9.328,95%CI:2.413~10.152,P=0.003)、居住地在城市(OR＝6.413,95%CI:2.748~8.503,P=0.015)、早餐地点在家里(OR＝6.349,95%CI:2.692~8.419,P=0.009)、周末活动时间<1 h(OR＝14.928,95%CI:4.210~15.384,P<0.001)均是儿童肥胖症的危险因素;观察组FPG及2 hPBG表达水平均显著高于对照组(P<0.05);观察组IFG、IGT及糖尿病发生率均显著高于对照组(P<0.05)。结论 儿童肥胖症的发生与外界及自身多项因素有密切联系,还可能诱发糖尿病等并发症,临床中应针对诱导儿童肥胖症产生的具体因素制定相应控制对策,改善肥胖患儿生活质量,使其健康成长。     

Human metabolism: pathways and clinical aspects

Metabolism describes the series of chemical reactions that are concerned with the provision of energy to biological systems. They may be divided into reactions involved in energy yield (catabolism: demand exceeds supply), and energy storage (anabolism: supply exceeds demand). Regulation of these pathways is critical for homeostasis, and derangements in metabolism are seen in a wide variety of pathological processes. Understanding metabolism is key to the treatment of many diseases, notably diabetes, as well as underpinning clinical nutritional support.
