Atypical Abnormal Pulmonary Vein Drainage with Atrial Septal Defect: Surgical Treatment

Sinus venosus atrial septal defect (SV‐ASD) usually coexists with partial anomalous pulmonary vein connection (PAPVC). It is a difficult diagnosis in transthoracic echocardiography (TTE) due to eccentric position of defects. We present a rare case of atypical anatomical variation in PAPVC, which was never described before. Two right pulmonary veins drained into superior vena cava, which overrode SV‐ASD and interatrial septum, a third pulmonary vein into the right atrium. Complete diagnosis could not be set after TTE, nor transesophageal echocardiography, whereas angio‐CT was finally conclusive. This diagnostic approach allowed the surgical planning.     

Gaining weight through retirement? Results from the SHARE survey

This paper estimates the causal impact of retirement on the Body Mass Index (BMI) of adults aged 50–69 years old, on the probability of being either overweight or obese and on the probability of being obese. Based on the 2004, 2006 and 2010–2011 waves of the Survey of Health, Ageing and Retirement in Europe (SHARE), our identification strategy exploits variation in European Early Retirement Ages (ERAs) and stepwise increases in ERAs in Austria and Italy between 2004 and 2011 to examine an exogenous shock to retirement behavior. Our results show that retirement induced by discontinuous incentives in early retirement schemes causes a 12-percentage point increase in the probability of being obese among men within a two- to four-year period. We find that the impact of retirement is highly non-linear and mostly affects the right-hand side of the male BMI distribution. Additional results show that this pattern is driven by men retiring from strenuous jobs and by those who were already at risk of obesity. In contrast, no significant results are found among women.     

维生素D与多囊卵巢患者胰岛素抵抗相关性及其机制研究

目的:探讨维生素D对多囊卵巢综合征(PCOS)患者胰岛素抵抗(IR)的影响及其机制研究.方法:选取自2013年2月～2014年2月在该院就诊的48例PCOS患者作为PCOS组,另选30例健康育龄期妇女作为对照组,测量研究者身高、体质量参数,计算体质指数(BMI),采用全自动生化分析仪葡萄糖氧化酶检测空腹血糖浓度(FBG)、化学发光法检测血清空腹胰岛素(FI)及胰岛素样生长因子-1(IGF-1)水平、ELISA方法测定血清25-(OH)D3浓度,计算稳态胰岛素评价指数(HOMA-IR)用于评价胰岛素抵抗性,量化胰岛素敏感指数(QUICKI)用于评价胰岛素敏感度,并分析FI、HOMA-IR、QUICKI及IGF-1与血清25-(OH)D3浓度的相关性.结果:PCOS组BMI及FBG与对照组相比,差异无统计学差异(P＞0.05),而FI、HOMA-IR、QUICKI、25-(OH) D3及IGF-1与对照组比较,差异均有统计学差异(P＜0.05);并且PCOS组FI和HOMA-IR与血清25-(OH)D3浓度呈显著负相关,差异有统计学意义(P＜0.05),QUICKI和IGF-1水平与血清25-(OH)D3浓度呈显著正相关,差异有统计学意义(P＜0.05).结论:PCOS患者IR可能与血清中维生素D缺乏有关,而IGF-1分泌减少又可能是导致PCOS患者维生素D缺乏的重要原因.     

Sudden Cardiac Death in Patients With Type 1 Versus Type 2 Diabetes

ObjectiveTo investigate the association between type 1 diabetes mellitus (T1D) and type 2 diabetes mellitus (T2D) with risk of sudden cardiac arrest (SCA).MethodsIn a prospective community-based study of SCA from February 1, 2002, through November 30, 2019, we ascertained 2771 cases age 18 years of age or older and matched them to 8313 controls based on geography, age, sex, and race/ethnicity. We used logistic regression to evaluate the independent association between diabetes, T1D, T2D, and SCA.ResultsPatients had a mean age of 64.5±15.9 years, were 33.3% female and 23.9% non-White race. Overall, 36.7% (n=1016) of cases and 23.8% (n=1981) of controls had diabetes. Among individuals with diabetes, the proportion of T1D was 6.5% (n=66) among cases and 2.0% among controls (n=40). Diabetes was associated with 1.5-times higher odds of SCA. Compared with those without diabetes, the odds ratio and 95% CI for SCA was 4.36 (95% CI, 2.81 to 6.75; P<.001) in T1D and 1.45 (95% CI, 1.30 to 1.63; P<.001) in T2D after multivariable adjustment. Among those with diabetes, the odds of having SCA were 2.41 times higher in T1D than in T2D (95% CI, 1.53 to 3.80; P<.001). Cases of SCA with T1D were more likely to have an unwitnessed arrest, less likely to receive resuscitation, and less likely to survive compared with those with T2D.ConclusionType 1 diabetes was more strongly associated with SCA compared with T2D and had less favorable outcomes following resuscitation. Diabetes type could influence the approach to risk stratification and prevention of SCA.     

Increased hospital costs are associated with low skeletal muscle mass in patients undergoing elective open aortic surgery

Objective

Low psoas muscle area is shown to be an indicator for worse postoperative outcome in patients undergoing vascular surgical. Additionally, it has been associated with longer durations of hospital stay in patients with cancer who undergo surgery and subsequently greater health care costs in Europe and the United States. We sought to evaluate this effect on hospital expenditure for patients undergoing vascular repair in a health care system with universal access.
