SummaryCoronary artery disease (CAD) is a major determinant of long-term prognosis in patients with peripheral artery disease (PAD). We investigated the predictors of CAD in patients with lower extremity PAD.A total of 107 patients with PAD who underwent peripheral and simultaneous coronary angiography were reviewed. PAD was defined as (≥ 50%) stenosis associated with claudication or critical limb ischemia. PAD was divided into proximal and distal lesions. CAD was defined as angiographically significant (≥ 50%) stenosis of coronary arteries.The prevalence of CAD in patients with PAD was 62% (67/107), and of this 62%, only 13% (9/67) had angina and 72% (48/67) had multi-vessel disease. Diabetes significantly increased the risk of CAD in patients with PAD and the odds ratio of having multi-vessel CAD was 2.5 (1.1-5.9, P = 0.037) in multivariate regression analysis. The patients with multi-vessel CAD had more cardiovascular risk factors than those with normal, minimal and single CAD (P = 0.032). Interestingly, the prevalence of proximal PAD was higher in the normal or single CAD group than the multi-vessel CAD group, whereas both proximal and distal involvement of PAD was higher in the multi-vessel CAD group.Diabetes, multi-cardiovascular risk factors, and involvement of both proximal and distal lesions significantly increased the risk of multi-vessel CAD. Therefore, simultaneous CAD evaluation should be considered in patients with lower extremity PAD having diabetes, multi-cardiovascular risk factors, or multi-level disease.

Background: There is limited information describing the presenting characteristics and dynamic clinical changes in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection diagnosed in the early phase of illness. This study is a case series of patients with coronavirus disease 2019 (COVID-19) admitted to 11 hospitals in Korea. Methods: Patients with confirmed SARS-CoV-2 infection by positive polymerase chain reaction (PCR) testing of respiratory specimens by active surveillance that were finally discharged between February 20 and April 30, 2020 were included. Patients were classified into mild and non-mild groups on initial admission according to oxygen demand and Sequential Organ Failure Assessment score, and the mild group was followed up and subgrouped into non-aggravation and aggravation groups. Results: A total of 161 patients with SARS-CoV2 infection were enrolled. Among the mild group of 136 patients, 11.7% of patients experienced clinical aggravation during hospitalization, but there was no initial clinical parameter on admission predicting their aggravation. Fever (odds ratio [OR], 4.56), thrombocytopenia (OR, 12.87), fever (OR, 27.22) and lactate dehydrogenase (LDH) > 300 U/L (OR, 18.35), and CRP > 1 mg/dL (OR, 11.31) significantly indicated aggravation in the 1st, 2nd, 3rd, and 4th 5-day periods, respectively. PCR positivity lasted for a median of 22 days and 32 days after the onset of illness in the nonaggravation and aggravation groups, respectively. Conclusion: Old age was associated with early severe presentation. Clinical aggravation

Background: This study was aimed at evaluating the food intake and nutritional status of patients who underwent gastrectomy for gastric cancer based on a large-scale gastric cancer cohort. Methods: An observational prospective cohort study for gastric cancer has been conducted since 2010. From the cohort data, we selected the data for patients who completed at least 2 days of 3-day diet diaries and who underwent subtotal gastrectomy (STG) or total gastrectomy (TG). As a control group, patients who underwent endoscopic submucosal dissection were also included. The collected diet data were converted to macro- and micronutrients using computerized software, and the nutrient intakes were compared. Results: Among 6,556 patients who participated in the cohort study from 2011 to 2016, 1,289 patients who completed at least 2 days of 3-day diet diaries were included in this study. During the postoperative 3-month period, body weight was significantly decreased in the and TG groups. However, there was no difference in nutrient intake among the 3 groups except vitamin D and calcium intake. Similar results were observed during the postoperative 12 months period. Conclusions: Postoperative body weight loss and anemia might originate from altered absorptive function and metabolic change after gastrectomy rather than decreased nutrient intake.

Presyncopal symptoms during NTG-stimulated HUTT are SVR mediated, not cardiac output mediated. This study challenges the conventional idea of a decrease in cardiac output mediated by NTG as the overriding cause of presyncopal symptoms during HUTT.
