Does the loot box open the door to addiction? A case report of gaming disorder with high charges for loot box purchases.

Background: A loot box is a gaming term for an electronic lottery that randomly provides items that enhance the gaming experience. In recent years, loot boxes have been increasingly discussed as a risk factor of gaming disorder (GD). While they may be purchased for a few dollars at a time, the cumulative expenses resulting from their addictive use have become a social problem.

Development and preliminary validation of the Group Cognitive Therapy Scale.

Aim: The aim of this research was to create a scale to assess the competency of therapists who conduct group cognitive behavioral therapy (G-CBT). The scale is intended to serve as a tool to aid the training of therapists.

Methods: Three stepped studies were conducted.

Door-to-Needle Time for Extracorporeal Cardiopulmonary Resuscitation and Neurological Outcomes in Out-of-Hospital Cardiac Arrest: A Nationwide Study.

Background: Extracorporeal cardiopulmonary resuscitation (ECPR) is an option for refractory cardiac arrest, and immediate initiation after indication is recommended. However, the practical goals of ECPR preparation (such as the door-to-needle time) remain unclear. This study aimed to elucidate the association between the door-to-needle time and neurological outcomes of out-of-hospital cardiac arrest.

Saccular and Fusiform Abdominal Aortic Aneurysms Treated With Endovascular Repair Differ in Presentation and Treatment Threshold: Analyses Using a National Clinical Database in Japan.

Background: Saccular abdominal aortic aneurysms (AAAs) are considered to be at higher risk of rupture than fusiform AAAs, but not much is known about the extent of this risk. Therefore, this study aimed to compare the rupture presentation between fusiform and saccular AAAs.

Methods And Results: This is a retrospective cohort study on 27 290 patients who underwent primary endovascular repair for a degenerative AAA between 2016 and 2019, and who were registered in the National Clinical Database in Japan.

Prognostic Value of Objective Social Isolation and Loneliness in Older Patients With Heart Failure: Subanalysis of FRAGILE-HF and Kitasato Cohort.

Background: Social factors encompass a broad spectrum of nonmedical factors, including objective (social isolation [SI]) and perceived (loneliness) conditions. Although social factors have attracted considerable research attention, information regarding their impact on patients with heart failure is scarce. We aimed to investigate the prognostic impact of objective SI and loneliness in older patients with heart failure.

Single coronary artery with aortic valve replacement followed by aortic root replacement due to endocarditis: A case report.

A woman with a single coronary artery underwent aortic valve replacement due to aortic stenosis. Two years later, she developed an aortic annular abscess around the right coronary cusp and non-coronary cusp. Significant adhesions to the right coronary artery (RCA) resulted from the abscess, making artery separation challenging, and raising concerns about potential future RCA stenosis.

Investigation of the impact of COVID-19 on postoperative outcomes using a nationwide Japanese database of patients undergoing laparoscopic distal gastrectomy and low anterior resection for gastric cancer and rectal cancer.

Background: The COVID-19 outbreak made conventional medical care impossible, forcing changes in both healthcare providers and patients. In Japan, COVID-19 infection began spreading in earnest in 2020 and exploded in 2021. There was concern that the medical impact of COVID-19 in 2021 would differ from that in 2020.

Effects of the COVID-19 pandemic on short-term postoperative outcomes for colorectal perforation: A nationwide study in Japan based on the National Clinical Database.

Aim: Possible negative effects of the COVID-19 pandemic on short-term postoperative outcomes for colorectal perforation in Japan were examined in this study.

Methods: The National Clinical Database (NCD) is a large-scale database including more than 95% of surgical cases in Japan. We analyzed 13 107 cases of colorectal perforation from 2019 to 2021.

A case of pulmonary primary MALT lymphoma with distinctive bronchoscopic findings.

Mucosa-associated lymphoid tissue (MALT) is a low-grade lymphoma, but cases in which it has transformed into a high-grade lymphoma have been reported, necessitating an accurate diagnosis. The patient was a 79-year-old nonsmoking Japanese female with history of ocular sarcoidosis. A computed tomography scan of her chest revealed a 35-mm nodule in the left S1 + 2, contiguous with the lymph nodes.

Efficacy of antithrombin administration for patients with sepsis: A systematic review, meta-analysis, and meta-regression.

Aims: There have been inconsistent reports regarding the effect of antithrombin on sepsis; furthermore, there are limited reports on how dosage affects therapeutic efficacy. Thus, we aimed to perform a systematic review and meta-analysis of the use of antithrombin for sepsis and a meta-regression analysis of antithrombin dosage.

Methods: We included randomized controlled trials (RCTs) and observational studies of adult patients with sepsis who received antithrombin.

Allogeneic hematopoietic cell transplantation for acute myeloid leukemia with fusion.

fusion is found in < 1% of de novo acute myeloid leukemia (AML) cases and confers a poor prognosis. This Japanese nationwide survey analyzed patients with AML ( = 22) and mixed phenotype acute leukemia (MPAL) ( = 10) with t(9;22) or who underwent allogeneic hematopoietic cell transplantation (allo-HCT) between 2002 and 2018. The 3-year overall survival (OS) rates were 81.

Use of current automatic smoke evacuation system in flexible gastrointestinal endoscopy: Its feasibility and potential usefulness.

Objectives: Flexible endoscopy does not have a system that can automatically evacuate surgical smoke generated in the gastrointestinal lumen. We aimed to investigate the feasibility and potential usefulness of automatic smoke evacuation systems in flexible endoscopy.

Methods: [Bench] After surgical smoke generated in the stomach was evacuated by the evacuator, the degree of residual smoke and gastric luminal collapse were evaluated to optimize the evacuator settings.
