A cross-sectional study on coronary artery disease diagnosis in patients with peripheral artery disease

PurposeCompared with healthy individuals, patients with peripheral artery disease (PAD) generally have a very high risk of subclinical Coronary artery disease (CAD) and cardiovascular events. To determine the correlation between CAD in PAD patients, thereby promoting the lifetime of PAD patients and reducing the serious impacts of CAD.MethodsThis clinical-based cross-sectional study comprised 100 consecutive patients in India from 2014 to 2016. In this research, PAD patients were screened for CAD by treadmill stress test and cardiac colour Doppler examination. In addition, this study performed coronary angiography followed by peripheral angiography for patients who could not perform the treadmill test.ResultsWith the statistical results, the study observed a high prevalence of CAD in PAD patients that can be detected only with angiography. Further, 30.93% of asymptomatic CAD prevalence was observed in PAD patients. The study strengthens the need for coronary angiography in all symptomatic lower limb PAD cases to detect early CAD, particularly in patients with diabetes and dyslipidemia.ConclusionThere exists a strong correlation between PAD and CAD. Hence, precise diagnosis followed by supervision of PAD patients is significant for avoiding local progression of cardiovascular risk.     

Gender differences in genotypic distribution of endothelin-1 gene and endothelin receptor A gene in pulmonary hypertension associated with rheumatic mitral valve disease

IntroductionThe female gender is a risk factor for idiopathic pulmonary arterial hypertension. However, it is unknown whether females with rheumatic mitral valve disease are more predisposed to develop pulmonary hypertension compared to males.AimWe aimed to investigate whether there was a difference in genotypic distribution of endothelin-1 (ET-1) and endothelin receptor A (ET_A) genes between female and male patients of pulmonary hypertension associated with rheumatic mitral valve disease (PH-MVD).MethodsWe compared prevalence of ET-1 gene (Lys198Asn) and ET_A gene (His323His) polymorphisms according to gender in 123 PH-MVD subjects and 123 healthy controls.ResultsThe presence of mutant Asn/Asn and either mutant Asn/Asn or heterozygous Lys/Asn genotypes of Lys198Asn polymorphism when compared to Lys/Lys in females showed significant association with higher risk (odds ratio [OR] 4.5; p =0.007 and OR 2.39; p =0.02, respectively). The presence of heterozygous C/T and either mutant T/T or heterozygous C/T genotypes of His323His polymorphism when compared to wild C/C genotype in females showed a significant association with higher risk (OR 1.96; p =0.047 and OR 2.26; p =0.01, respectively). No significant difference was seen in genotypic frequencies in males between PH-MVD subjects and controls. Logistic regression analysis showed that mutant genotype Asn/Asn (p =0.007) and heterozygous genotype Lys/Asn of Lys198Asn polymorphism (p =0.018) were independent predictors of development of PH in females.ConclusionsET-1 and ET_A gene polymorphisms were more prevalent in females than males in PH-MVD signifying that females with rheumatic heart disease may be more susceptible to develop PH.

目的:探讨肝移植受者延续护理中应用远程随访管理系统的效果。方法:挑选2018年6月—2019年12月医院接受治疗的60例肝移植受者,在其出院后2周以自制的远程随访管理系统对其展开居家延续护理。结果:医护小组达成了对受者术后疾病状况的远程监控,通过视频交流为病人提供706例次健康指导。所有研究对象对远程随访管理系统的接受率、掌握率、应用时间、每次视频交流时间分别为81.08%、100.00%、(10.53±2.49)d、(12.13±2.69)min。肝移植受者满意度最高的3项依次是视频交流方式、延续护理模式、指导或者咨询内容;延续护理小组满意度最高的3项依次是病情变化处理方法、视频交流方式、指导或者咨询内容。结论:通过远程随访管理,为肝移植受者开展延续护理是现实可行的,不但能使肝移植受者的术后自我管理能力得到有效提升,且受者及延续护理小组都对此系统的应用具有较高的满意度。     

弹性抗阻运动对慢性阻塞性肺疾病康复疗效的Meta分析

目的 系统评价弹性抗阻运动(弹力带/弹力管)对慢性阻塞性肺疾病(COPD)患者康复疗效的影响。方法 检索Cochrane Library、PubMed、Web of Science、中国知网、维普、万方和生物医学文献数据库中关于弹性抗阻运动治疗COPD患者的临床随机对照试验,检索时限自建库至2020年9月。最后纳入文献11篇,其中英文9篇,中文2篇,共485例患者。采用Cochrane风险偏倚评估工具及物理治疗证据数据库量表进行质量评价,采用RevMan 5.2软件进行分析。这一系统评价在PROSPERO(CRD42020208659)上登记。结果 弹性抗阻运动组与传统抗阻运动组(如举重训练机、体重训练) 6 min步行试验距离(6WMD) (MD = 1.19, 95%CI -7.02~9.39, P = 0.78)、COPD患者自我评估测试(CAT) (MD = -0.43, 95%CI -2.42~1.57, P = 0.68)和肌力(MD = 0.23, 95%CI -1.06~1.52, P = 0.73)无显著性差异,两组间异质性不高。弹性抗阻运动组与非抗阻运动组6MWD (MD = 18.30, 95%CI -8.92~45.52, P = 0.19)和CAT (MD = -0.59, 95%CI -3.78~2.60, P = 0.72)无显著性差异,研究间异质性较高。结论 弹性抗阻运动也许是一种潜在的替代传统抗阻训练的方法,但弹性抗阻运动对运动耐力、生活质量、肺功能的影响尚不明确。     

COVID-19 Gender Disparities and Mitigation Recommendations: A Narrative Review

The coronavirus disease 2019 (COVID-19) pandemic has rapidly created widespread impacts on global health and the economy. Data suggest that women are less susceptible to severe illness. However, sex-disaggregated data are incomplete, leaving room for misinterpretation, and focusing only on biologic sex underestimates the gendered impact of the pandemic on women. This narrative review summarizes what is known about gender disparities during the COVID-19 pandemic and the economic, domestic, and health burdens along with overlapping vulnerabilities related to the pandemic. In addition, this review outlines recommended strategies that advocacy groups, community leaders, and policymakers should implement to mitigate the widening gender disparities related to COVID-19.     

Adherence to Chronic Kidney Disease Screening Guidelines Among Patients With Type 2 Diabetes in a US Administrative Claims Database

ObjectiveTo examine the screening rates for kidney damage and function among patients with type 2 diabetes (T2D) and chronic kidney disease stage at diabetes diagnosis using a US administrative claims database.Patients and MethodsThis cohort study used a claims database enriched with laboratory results data. Patients with T2D (defined as 1 inpatient or 2 outpatient claims for diabetes), aged 18 years or older, and with at least 1 year of follow-up enrollment were identified. Patients with type 1 diabetes, kidney disease, or other related conditions at baseline were excluded. We estimated screening rates using laboratory orders for serum creatinine and estimated glomerular filtration rate (eGFR) measurement and urine albumin to creatinine ratio (UACR). Chronic kidney disease severity was reported using the Kidney Disease: Improving Global Outcomes classification based on laboratory results.ResultsA total of 1,881,447 patients with T2D were eligible for analysis. Mean ± SD age was 63.1±13.1 years; 947,150 patients (50.3%) were male. Serum creatinine tests were ordered within 14 days of the index date among 290,722 patients of 622,915 (46.7%) patients with newly-recognized T2D. Overall, 1,595,964 patients (84.8%) had at least one serum creatinine test ordered during the 1-year follow-up period. Fewer patients received a UACR test during follow-up (814,897 [43.3%]). Less than half of all patients with T2D received a laboratory test order for both serum creatinine and urine albumin measurements during the follow-up period.ConclusionPhysicians treating patients with diabetes are selectively adhering to chronic kidney disease screening guidelines, as indicated by high rates of eGFR testing, but less frequent UACR testing. Despite recommendations to monitor both eGFR and UACR, less than half of patients were screened for albuminuria during the 1-year follow-up.
