		                        			Surgery for an atrioventricular septal defect (AVSD) is rare in septuagenarians. This is the case of a 75-year-old man with partial AVSD. He developed dyspnea on exertion. Detail examinations revealed partial AVSD, severe left atrioventricular valve (LAVV) regurgitation, severe right atrioventricular valve (RAVV) regurgitation, persistent atrial fibrillation, and coronary artery stenosis, which required surgical intervention. Subsequently, we performed ostium primum-type atrial septal defect closure using an autologous pericardium patch, LAVV replacement with a bioprosthetic valve, RAVV repair without annuloplasty, a modified Maze IV procedure, left atrial appendage closure, and coronary artery bypass grafting. Although LAVV repair for LAVV regurgitation was initially performed, it was converted to LAVV replacement because the repair could not control the regurgitation due to advanced degenerative changes with the thickening of the leaflets. The patient was discharged on the 15th postoperative day uneventfully. One and a half years after surgery, he had neither cardiovascular events nor arrhythmias.

		                        			A 74-year-old man, with a medical background of cryoglobulinemia, had been undergone nonbacterial thrombotic endocarditis with immunotherapy spanning three months. Following a year and three months, he has presented to our institution experiencing acute decompensated heart failure attributable to severe aortic regurgitation (AR),moderate mitral regurgitation (MR),and severe tricuspid regurgitation (TR).Transesophageal echocardiography revealed aortic valve cusps destruction and anterior mitral valve leaflet vegetation. The potential complications of leukocytoclastic or necrotizing vasculitis due to hypothermic cardiopulmonary bypass in cryoglobulinemia patients were addressed preemptively through preoperative plasmapheresis. During the procedure, tepid core cooling cardiopulmonary bypass at 33℃ and tepid blood cardioplegia solution at 30℃ were employed to mitigate the risk of vasculitis. Urgent aortic valve replacement, mitral vegetation resection, and tricuspid annuloplasty were performed, and the patient was discharged on the 23rd postoperative day without any untoward events.

		                        			 Methods:
		                        			In total, 828 patients (338 males and 490 females; mean age, 65.0 years) who underwent spinal instrumentation surgery from 2013 to 2021 in Kyorin University School of Medicine were retrospectively investigated. Patients were divided into the SSI (group I) and non-SSI (group N) groups. Patient characteristics, comorbidity, laboratory, and surgical factors were investigated. Univariate analysis was performed for each item, and multivariate logistic regression analysis was performed for items with significant differences. 
		                        		
		                        			Results:
		                        			Fifteen patients (1.85%) had SSIs. Univariate analysis revealed significant differences between groups I and N in history of steroid use, serum albumin, C-reactive protein, number of fixed vertebrae, and perioperative blood transfusion. Multivariate logistic regression analysis showed that a history of steroid use (odds ratio [OR], 5.38; 95% confidence interval [CI], 1.41–20.49; p=0.014), serum albumin (OR, 0.34; 95% CI, 0.13–0.84; p=0.020), and perioperative blood transfusion (OR, 5.85; 95% CI, 1.46–23.50; p=0.013) were independent risk factors for SSIs. 
		                        		
		                        			Conclusions
		                        			The results of this study indicate that preoperative nutritional intervention, appropriate management of anemia, and intraoperative and postoperative bleeding control may decrease the incidence of SSIs. However, this study has several limitations, including its retrospective design, analysis of a few SSI cases, and inclusion of various surgical approaches and disease types. Future studies that address these limitations are desirable.

		                        			 Methods:
		                        			A total of 224 consecutive patients with OVFs aged ≥65 years who received treatment within 2 weeks after the occurrence of injury were enrolled. The patients were followed up for 6 months thereafter. The criteria for evaluating the degree of independence were applied to evaluate ADLs. Multivariable analysis with a logistic regression model was performed to evaluate the risk factors for ADL decline. 
		                        		
		                        			Results:

		                        			 With increasing global life expectancy, the significance of geriatric assessment parameters has increased. Sarcopenia is a crucial assessment parameter and is defined as the age-related loss of muscle mass and strength. Sarcopenia is widely acknowledged as a risk factor for postoperative complications in diverse advanced malignancies and has a detrimental effect on the long-term prognosis. While most studies have primarily concentrated on the correlation between sarcopenia and advanced cancer, more recent investigations have focused on the relationship between sarcopenia and early-stage cancer. Endoscopic submucosal dissection (ESD), which is less invasive than surgical intervention, is extensively employed in the management of early-stage cancer, although it is associated with complications such as bleeding and perforation. In recent years, several reports have revealed the adverse consequences of sarcopenia in patients with early-stage cancer undergoing ESD. This literature review briefly summarizes the recent studies on the association between sarcopenia and ESD.

		                        			Background/Aims:
		                        			5-Aminosalicylic acid (5-ASA) is a basic drug for inducing and maintaining remission for ulcerative colitis. One of its formulations has a coating with a pH-dependent degradation that ensures the release 5-ASA at the terminal ileum. No evidence has been shown concerning the effects of proton pump inhibitors (PPIs) or H2 receptor antagonists (H2RAs) on the clinical course of ulcerative colitis patients in remission. The present study assessed the effect of PPIs or H2RAs on the relapse of ulcerative colitis patients in clinical remission maintained by pH-dependent released 5-ASA. 
		                        		
		                        			Methods:
		                        			Ulcerative colitis patients who had been prescribed time- or pH-dependent-released 5-ASA between January 2015 and December 2018 were enrolled in this multicenter retrospective study. The period of remission until relapse occurred was analyzed among the patients taking time-dependent-released 5-ASA or pH-dependent-released 5-ASA with/without PPIs or H2RAs. 
		                        		
		                        			Results:
		                        			One hundred and nineteen patients were analyzed in this study. In the primary endpoint, the relapse rate was higher in patients taking pH-dependent-released 5-ASA and PPIs or H2RAs than in those taking the pH-dependent-released 5-ASA without PPIs or H2RAs, while the relapse rate was similar in patients taking the time-dependent-released 5-ASA with or without PPIs or H2RAs concomitantly. Patients with a short duration of disease and middle-aged patients more frequently showed relapse with PPIs or H2RAs than the other patients. 
		                        		
		                        			Conclusions
		                        			The coadministration of PPIs or H2RAs affects the clinical course of ulcerative colitis in remission maintained by pH-dependent-released 5-ASA.

		                        			Objective: To report a case of anterior longitudinal ligament (ALL) injury that was not noticeable during lateral lumbar interbody fusion and was disclosed after posterior corrective fusion surgery.Case presentation: After performing lateral lumbar interbody fusion followed by posterior corrective fusion surgery, we observed an anterior longitudinal ligament rupture that required additional surgery. Postoperative pain in the left lower limb and muscle weakness due to nerve traction appeared, but this was improved by stabilization between the vertebral bodies.Conclusion: Unidentified anterior longitudinal ligament rupture can result in unexpected local lordosis during posterior surgery, possibly related to lower extremity palsy. Therefore, checking for possible rupture during and after anterior surgery is important. If the ALL damage is disclosed before posterior surgery, the proper surgical strategy for the posterior surgery must be considered.
