Background/Aims: We aimed to clarify the clinicopathological characteristics and causes of Barrett’s esophageal adenocarcinoma (BEA) with unclear demarcation. Methods: We reviewed BEA cases between January 2010 and August 2022. The lesions were classified into the following two groups: clear demarcation (CD group) and unclear demarcation (UD group). We compared the clinicopathological findings between the two groups. Furthermore, we measured the length and width of the foveolar structures, as well as the width of marginal crypt epithelium (MCE). Results: We analyzed data from 68 patients with BEA, including 47 and 21 in the CD and UD groups, respectively. Multivariate analysis revealed long-segment Barrett’s esophagus (LSBE) as the sole significant risk factor for BEA (odds ratio, 12.17; 95% confidence interval, 2.84–47.6; p=0.001). Regarding pathological analysis, significant differences were observed in the length and width of the foveolar structure between cancerous and surrounding mucosa in the CD group (p=0.03 and p=0.00, respectively); however, no significant difference was observed in the UD group (p=0.53 and p=0.72, respectively). Nevertheless, the width of MCE in the cancerous area was significantly shorter than that in the surrounding mucosa in both groups (p<0.05, and p<0.05, respectively). Conclusions LSBE is a significant risk factor for BEA in the UD group. The width of MCE may be an important factor in the endoscopic diagnosis of BEA.

Background/Aims: Endoscopic ultrasound (EUS)-guided pancreatic duct drainage is a well-established procedure for managing pancreaticojejunostomy anastomotic strictures (PJAS) post-Whipple surgery. In this study, we examined the effectiveness and safety of EUS-guided pancreaticojejunostomy (EUS-PJS). Methods: This retrospective, single-arm study was performed at Aichi Cancer Center Hospital on 10 patients who underwent EUS-guided pancreaticojejunostomy through the afferent jejunal loop using a forward-viewing echoendoscope when endoscopic retrograde pancreatography failed. Our primary endpoint was technical success rate, defined as successful stent insertion. The secondary endpoints were early and late adverse events. Results: A total of 10 patients underwent EUS-PJS between February 2019 and October 2023. The technical success rate was 100%. The median procedure time was 23.5 minutes. No remarkable early or late adverse events related to the procedure, except for fever, occurred in two patients. The median follow-up duration was 9.5 months, and the median number of stent exchanges was two. A stent-free state was achieved in three patients. Conclusions EUS-PJS for PJAS management after pancreaticoduodenectomy appears to be an effective and safe procedure with the potential advantages of fewer reinterventions and the creation of a permanent drainage fistula.

Background/Aims: Biliary obstruction drainage in patients with hepatocellular carcinoma (HCC) is associated with symptom palliation, improved access to chemotherapy, and improved survival. Stent placement and exchange via endoscopic retrograde cholangiopancreatography biliary drainage risk traversing the HCC, a hypervascular tumor and causing bleeding. Endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) potentially prevents procedure-related bleeding. Therefore, we evaluated the efficacy and safety of EUS-HGS as an alternative treatment for biliary obstruction in patients with HCC. Methods: This was a retrospective study of all EUS-HGS procedures performed in patients with HCC at the Aichi Cancer Center Hospital, Japan, from February 2017 to August 2023. Results: A total of 14 EUS-HGS procedures (42.9% primary) were attempted in 10 HCC patients (mean age 71.5 years, 80.0% male). Clinical and technical success rates were 92.9% and 90.9%, respectively. The observed procedure details in the 13 successful procedures included B3 puncture (53.8%), 22-G needle (53.8%), fully covered self-expandable metal stent (100%), and mean procedure time (32.7 minutes). There was no bleeding. Mild complications occurred in 27.3%. All patients resumed oral intake within 24 hours. Conclusions EUS-HGS is a technically feasible and clinically effective initial or salvage drainage option for the treatment of biliary obstruction in patients with HCC.

Background: In the Latarjet procedure, the subscapularis is divided at the superior two-thirds junction. It has been believed that this subscapularis split approach resulted in better internal rotation strength rather than an L-shaped subscapularis tenotomy. However, there are few studies demonstrating the preserved function of the subscapularis after the Latarjet procedure. The aim of the present study was to clarify the subscapularis activity using positron emission tomography (PET) in patients after the Latarjet procedure. Methods: Six men who had undergone the Latarjet procedure were enrolled. The internal rotation exercise with elastic bands was performed with the arm at 0° and 90° of abduction. After the exercises, the patients had an intravenous injection of fluorine 18 fluorodeoxyglucose ( 18 F FDG). Each PET image was fused to the corresponding computed tomography image to calculate the standardized uptake value (SUV). The internal rotation muscle strength was measured by a dynamometer. Results: At 0° of abduction, the subscapularis SUVs of the involved side were significantly lower than those of the uninvolved side (p = 0.010), although there was no significant difference at 90° of abduction. The SUVs of the involved subscapularis were significantly lower at 0° of abduction than at 90° (p = 0.034). The internal rotation strength of the involved side was 81.1% ± 12.1% of the uninvolved side at 0° of abduction. Conclusions After the Latarjet procedure with the subscapularis split approach, subscapularis activity was well preserved at 90° of abduction. However, internal rotation strength was reduced by 19%.

This review aims to evaluate the safety of remimazolam for intravenous sedation during dental treatment and oral surgery. The protocol was registered in the Open Science Framework (registration DOI: 10.17605/OSF.IO/RFPSZ), and reporting followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR). Literature searches and screenings were conducted using PubMed and the Cochrane database, with additional records manually reviewed from various sources. The selected studies, published in English, investigated the safety of remimazolam for sedation in dental and oral surgery. An initial search identified 20 studies, of which five prospective studies met the inclusion criteria. All included studies used an initial bolus administration of remimazolam. Primary outcomes assessed were the sedation success rate, incidence of adverse effects, onset time, awakening time, recovery time, and postoperative side effects. This scoping review indicates that all studies validated the superiority of remimazolam over other sedatives for dental treatment and oral surgery. The development and research of innovative technologies to reduce dental pain and anxiety presents opportunities for interdisciplinary collaboration and improved patient care in dental practice.Future clinical studies should focus on determining the optimal timing for additional dosing and discontinuation when remimazolam is administered continuously.

INTRODUCTION

Heart failure (HF) is a common cause of hospitalization, heart failure-related readmission, poor quality of life, and mortality. It also poses a substantial economic burden. The heart failure clinical practice guideline (HFCPG) was developed to provide evidence-based recommendations on the diagnosis and management of chronic HF with reduced ejection fraction (HFrEF) among adult Filipino patients in the outpatient setting for primary care physicians.

The GRADE approach and an Evidence-to-Decision framework were used to evaluate the evidence and formulate recommendations. The strength and direction of each recommendation were determined through voting, with consensus reached if 75% of all CP members agreed.

The HFCPG provides 19 recommendations and one good practice statement in response to 14 identified clinical questions. Careful history-taking and physical examination, use of chest x-ray to detect cardiomegaly and/or pulmonary congestion, two-dimensional echocardiography for HF diagnosis, and baseline determination of serum sodium, potassium, and creatinine to guide management have been highly recommended; however, the 12-lead electrocardiogram should not be solely used for HF diagnosis. Judicious use of diuretics to relieve congestion, use of selected beta-blockers, renin-angiotensin-aldosterone blockers, mineralocorticoid receptor antagonists, and SGLT2 inhibitors are strongly recommended for the treatment of HFrEF.

HFrEF is a complex condition that requires early recognition and careful management. Guideline-directed medical therapies, particularly the evidence-based pillars of treatment, are recommended, as well as early discussion of palliative care, timely determination of advanced heart failure and the need for referral to higher levels of care.

BACKGROUND: This cohort study aimed to identify the accumulation patterns of objectively measured ambulatory activity (AA) variables in the middle-aged and older Japanese women and examine the relationship of these derivative patterns with onset of metabolic syndrome (MetS). METHODS: A total of 794 women (mean age: 56.2 years) provided objectively assessed AA data using a uniaxial accelerometer. The number of steps, time accumulated in light-intensity AA (LIAA) and moderate-to-vigorous intensity AA (MVAA) and the ratio of MVAA to total AA (LIAA + MVAA) were calculated. Latent profile analysis was used to identify participant groups based on their distinct AA patterns. Logistic regression models were used to assess the association of groups with the onset of MetS after adjusting for age, sex, education, alcohol habit, smoking habit, energy intake, and the number of MetS components present at baseline. RESULTS: Four distinct groups were identified: Group A had low levels of the AA variable; group B accumulated a certain number or more steps primarily through MVAA; group C accumulated a certain number or more steps primarily through LIAA; and group D had high level of the AA variables. Over the course of the 5-year follow-up period, 61 participants (7.7%) developed MetS. The multivariate-adjusted odds ratio (95% confidence interval) for onset of MetS in groups B, C, and D relative to group A were 0.416 (0.166-1.218), 0.451 (0.223-0.914), and 0.933 (0.365-2.382), respectively. Group C had a significantly lower odds ratio of MetS onset than group A. CONCLUSION AA patterns accumulating a certain number or more steps, regardless of the intensity of AA, may help reduce the risk of MetS compared to inactive AA patterns.

BACKGROUND: SARS-CoV-2 (COVID-19) is transmitted via infectious respiratory particles. Infectious respiratory particles are released when an infected person breathes, coughs, or speaks. Several studies have measured respiratory particle concentrations through focusing on activities such as breathing, coughing, and short speech. However, few studies have investigated the effect of speech duration. METHODS: This study aimed to clarify the effects of speech duration and volume on the respiratory particle concentration. Study participants were requested to speak at three voice volumes across five speech durations, generating 15 speech patterns. Participants spoke inside a clean booth where particle concentrations and voice volumes were measured and analyzed during speech. RESULTS: Our findings suggest that as speech duration increased, the aerosol number concentration also increased. Through focusing on individual differences, we considered there might be super-emitters who emit more aerosol particles than the average human. Two participants were identified as statistical outliers (aerosol number concentration, n = 1; mass concentration, n = 1). CONCLUSIONS Considering speech duration may improve our understanding of respiratory particle concentration dynamics. Two participants were identified as potential super-emitters.
