This study aimed to investigate the effects of participating in a voluntary community-based square-stepping exercise (SSE) salon and analyze the effects of different activity frequencies (weekly or biweekly) in the SSE salon on the physical functions of community-dwelling older women. Older women attending the SSE salon were enrolled in the study, and measurements of physical functions (grip strength, one-leg standing, 5 m walk, timed up and go [TUG], and chair-stand in 30 s) were performed at pre and post intervention for SSE salon development and at 1 year following voluntary activity initiation (1-year follow-up) (mean age: 77.1 ± 7.2 years). Participants were divided into two groups (a weekly group performing SSE once a week and a biweekly group performing SSE once every 2 weeks) and were analyzed accordingly. The results revealed interaction in the TUG test, with significant improvement observed in the weekly group at preintervention, postintervention, and 1-year follow-up. Conversely, the biweekly group significantly improved at the 1-year follow-up compared with the pre and postintervention groups. No significant difference was observed in other parameters. In conclusion, regular participation in the SSE salon, even if the frequency is biweekly, was suggested to be effective in maintaining and improving physical function.

A 61-year-old male presented to another hospital with sudden chest and back pain, and CT revealed a diagnosis of type A acute aortic dissection with patent false lumen. The ascending aortic diameter was 45 mm and the right common carotid artery was occluded. There were no neurological abnormalities, no pericardial effusion, and only mild AR. Eight hours after onset, the patient was transferred to our hospital. The laboratory data showed severe DIC with fibrinogen <50 mg/dl, so that medical DIC treatment was given first because of the high risk of bleeding. Twenty-two hours after the onset, DIC improved and surgery was initiated. The right common carotid artery was ligated for fear of thrombus dispersion at the periphery of the occlusion site. An ascending arch replacement was then performed. Postoperative hemostasis was good, and no new neurological abnormalities were observed. Usually, type A acute aortic dissection is indicated for emergency surgery, but in this case, DIC treatment took precedence. We report here a rare experience.

Convexity dural arteriovenous fistula (dAVF) is associated with high-grade dAVF and is usually presented with aggressive clinical presentation. Precise diagnosis and understanding the pathogenesis are important to achieving successful treatment without complications. We report a case of dAVF with Sylvian-Labbé collateral pattern, concerning embryological development that was thought to be involved in the vascular architecture and pathogenesis of dural AVF. Thus, a 60-year-old man was presented with sudden onset of seizure with no history of trauma. Magnetic Resonance Imaging (MRI) showed cortical hemorrhage in the left precentral gyrus. Digital subtraction angiography (DSA) showed the convexity dural arteriovenous fistula (dAVF) involving a vein that appeared to be the vein of Labbé, the drainer was anastomosed with superior middle cerebral vein (SMCV) and formed the varix. With the successful treatment with trans-arterial embolization (TAE), obliteration of dAVF was achieved with no neurological deficits. This case highlights convexity dAVF with the complex relationship between embryological development and the arcade of venous drainage route, wherein the anomaly might be acquired and caused by elevated venous pressure in a vein that appeared to be the vein of Labbé. Gaining knowledge of the embryological basis may aid in a deeper understanding of acquired pathologies.

Background/Aims: A latex agglutination turbidity (LA) assay to test for serum antibodies has been approved in Japan and Korea for mass screening of Helicobacter pylori infection. In this study, we evaluated the LA assay for diagnosing H. pylori infection and predicting gastric mucosal changes in a Mongolian population. Methods: In total, 484 individuals were classified into H. pylori-positive (n=356) and H. pylorinegative (n=128) groups, as determined by histology and H. pylori culture. Results: The best cutoff, sensitivity, and specificity values for the LA assay were 18.35 U/mL, 74.2%, and 65.6%, respectively. The LA values in the atrophic gastritis group were statistically higher than those in the other groups (healthy, chronic gastritis, intestinal metaplasia, and gastric cancer, p<0.0001). The cutoff value to distinguish the atrophic gastritis group from the other four groups was 32.0 U/mL, and its area under the curve was 0.673, which was the highest among the E-plate, pepsinogen (PG) I, PG II, and PG I/II ratio tests in our data. The odds ratios for atrophic gastritis determined by the LA assay and PG I test in multiple logistic regression were 2.5 and 1.9, respectively, which were significantly higher than for the other tests. Conclusions The LA assay can determine the risk of atrophic gastritis, which in turn is a considerable risk factor for gastric cancer. We propose using this assay in combination with the PG I/II ratio to avoid missing gastric cancer patients who have a low LA value (less than 32.0 U/mL).
