SGLT2 inhibitors for the treatment of diabetes: a patent review (2013-2018)

Introduction: The sodium-glucose co-transporter 2 (SGLT2) is ascribed to target renal tubular glucose re-absorption, and its inhibition has been proved to induce glucosuria which improves the glycemic index. Accordingly, SGLT2 inhibitors have found to be the promising class of antidiabetic agents for the management of type 2 diabetes mellitus. A large number of SGLT2 inhibitors have developed through structural modification and investigated for their ability to selectivity inhibit SGLT2 transporters with better bioavailability.

Areas covered: This review comprises a summary of patent applications (2013–2018) of SGLT2 inhibitors with focus on chemical structural advancement and therapeutic potentials in the management of diabetes and related disorders.

Expert opinion: SGLT2 inhibitors exert multiple metabolic benefits, including reduced glycated hemoglobin (HbA1c), improved glycemic control (fasting and postprandial), reduced body weight, reduced systolic and diastolic blood pressure and improved HDL cholesterol. Due to the virtue of no interference with insulin action and secretion, their efficacy remains the same even in presence of progressive β cell failure in type 2 diabetes. Additionally, few members of this class have been reported to exhibit cardioprotective, renoprotective, and anticancer activity. However, more study on the long-term outcomes in patients taking SGLT2 inhibitors is warranted.     

Atención prehospitalaria urgente de los pacientes pediátricos expuestos a tóxicos: características epidemiológico-clínicas y evaluación de la calidad asistencial

ObjectiveTo describe the characteristics of paediatric patients with suspected poisoning treated by advanced life support (ALS) units, and to evaluate quality indicators (QI) for the prehospital emergency care of these patients.MethodA one-year observational study of patients under 18 years of age exposed to poisoning and treated by an ALS unit of the Medical Emergency System in Catalonia. Severe clinical criteria were defined, with 8 QI being evaluated for prehospital emergency care of poisoned paediatric patients.ResultsThe study included a total of 254 patients, with a median age of 14 years-old (p25-75 = 7-16), with intentional poisoning in 50.8% of cases. The most frequently involved toxic agent was carbon monoxide (CO) (33.8%). Poisoning was found in 48.8% of those patients, being serious in 16.5%. Intentionally (OR 5.1; 95% CI: 1.9-13.8) and knowledge of the time of exposure (OD 3.1; 95% CI: 1.3-7.3) were independent risk factors associated with the appearance of severe clinical symptoms. Five QI did not reach the quality standard and included, availability of specific clinical guidelines, activated charcoal administration in selected patients, oxygen therapy administration at maximum possible concentration in carbon monoxide poisoning, electrocardiographic assessment in patients exposed to cardiotoxic substances, and recording of the minimum data set.ConclusionsPaediatric patients attended by ALS units showed specific characteristics, highlighting the involvement of CO and adolescents with voluntary poisoning. The QI assessment was useful to detect weak points in the quality of care of these patients and to develop strategies for improvement.     

风池穴不同刺法对椎动脉型颈椎病的临床疗效评价

目的:探究风池穴不同刺法对椎动脉型颈椎病的临床疗效。方法:选择2018年4月—2019年1月北京中医药大学东直门医院针灸科门诊就诊的84例椎动脉型颈椎病患者作为研究对象,分为观察组43例、对照组41例。观察组采用短刺法针刺风池穴治疗,对照组采用平补平泻法针刺风池穴治疗,1个疗程后比较两组患者的ESCV、颈椎病症状分级量化表评分以及TCD相关指标,TCD指标观察基底动脉和双侧椎动脉的平均血流速度(Vm)、收缩期血流速度峰值(Vs)、血管搏动指数(PI)和血管阻力指数(RI)的变化。结果:治疗前后两组ESCV、颈椎病症状分级量化表评分比较,差异有统计学意义(P<0.05),且椎动脉、基底动脉的Vs、Vm较治疗前明显减慢,且观察组治疗效果优于对照组(P<0.05)。结论:针刺风池穴治疗椎动脉型颈椎病临床效果显著,且短刺法优于平补平泻法。
