Association of sleep quality with duty hours, mental health, and medical errors among Japanese postgraduate residents: a cross-sectional study.

Long duty hours (DH) impair sleep and negatively affect residents' health and medical safety. This cross-sectional study investigated the association among residents' DH, sleep duration, insomnia, sleep impairment, depressive symptoms, and self-reported medical errors among 5579 residents in Japan who completed the General Medicine In-Training Examination (2021) and participated in the training-environment survey. Weekly DH was classified under seven categories.

Comparing Efficacy Between Robust and PTV Margin-based Optimizations for Interfractional Anatomical Variations in Prostate Tomotherapy.

Background/aim: Interfractional anatomical variations cause considerable differences between planned and actual radiotherapy doses. This study aimed to investigate the efficacy of robust and planning target volume (PTV) margin-based optimizations for the anatomical variations in helical tomotherapy for prostate cancer.

Patients And Methods: Ten patients underwent treatment-planning kilovolt computed tomography (kVCT) and daily megavolt computed tomography (MVCT).

Risk Assessment of Permanent Pacemaker Implantation After Transcatheter Aortic Valve Implantation in Patients With Preexisting Right Bundle Branch Block.

Preexisting right bundle branch block (RBBB) is the strongest predictor for permanent pacemaker implantation (PPI) after transcatheter aortic valve implantation (TAVI). However, the risk assessment for new PPI and effective procedural strategy for preventing new PPI in patients with preexisting RBBB are still unclear. This study stratified the new PPI risk after TAVI and investigated the impact of implantation strategy in a preexisting RBBB cohort.

Impella-Supported Surgical Repair for Acute Phase Posterior Ventricular Septal Rupture.

A 72-year-old man was diagnosed with posterior ventricular septal rupture after acute myocardial infarction with dissection in the posterior wall of the ventricular septum. On admission, cardiogenic shock was identified, and an Impella CP was inserted to improve his hemodynamics. Extended sandwich patch repair through the right ventricle with a Dacron patch was successfully performed, achieving an excellent postoperative course with stable hemodynamics.

Clinical Implication of Supra-Normal Left Ventricular Ejection Fraction in Patients Undergoing Transcatheter Aortic Valve Replacement.

Background: Individuals with heart failure displaying supra-normal left ventricular ejection fraction (snLVEF) may exhibit less favorable clinical outcomes in contrast to their counterparts with normal left ventricular ejection fraction (nLVEF). The distinctive characteristics and mid-term prognosis of individuals with severe aortic stenosis and snLVEF following transcatheter aortic valve replacement (TAVR) remain enigmatic.

Methods: Among 7393 patients diagnosed with severe aortic stenosis who underwent TAVR between 2013 and 2019 and were enlisted in the optimized transcatheter valvular intervention (OCEAN-TAVI) multicenter registry (UMIN000020423), we selected patients with left ventricular ejection fraction (LVEF) ≥ 50%.

Difference in tissue temperature change between two cryoballoons.

Background: Cryoballoon ablation, especially Arctic Front Advance Pro (AFA-Pro) (Medtronic, Minneapolis, Minnesota, USA), has been widely recognised as a standard approach to atrial fibrillation (AF). Recently, Boston Scientific has released a novel cryoballoon system (POLARx). Despite comparable acute clinical outcomes of these two cryoballoons, the recent study reported a higher complication rate, especially for phrenic nerve palsy, with POLARx.

Incidence, clinical course, and risk factors in the development of femoral pseudoaneurysm after atrial fibrillation ablation.

Background: Previous studies have revealed the risk factors for femoral pseudoaneurysms (FPA). Most data on FPA are based on coronary and peripheral interventions, with limited studies focusing on atrial fibrillation (AF) ablation. However, patient backgrounds, anticoagulation regimens, and vascular access methods differ.

Five-year outcomes in carbon-ion radiotherapy for postoperative pelvic recurrence of rectal cancer: A prospective clinical trial (GUNMA 0801).

Introduction: Carbon-ion radiotherapy (C-ion RT) is associated with favorable clinical outcomes for the pelvic recurrence of rectal cancer. However, few long-term follow-up studies after C-ion RT have been conducted. Hence, we performed an updated analysis of a prospective clinical trial of C-ion RT for the postoperative pelvic recurrence of rectal cancer.

Long-Term Assessment of Survival After Transcatheter Aortic Valve Implantation - Insights From the International Transcatheter Aortic Valve Implantation Registry.

Background: Transcatheter aortic valve implantation (TAVI) is an established treatment for severe aortic stenosis (AS), but despite estimates of life expectancy after TAVI being essential in heart team discussion, these data are scarce. Therefore, the current study sought to assess long-term survival and its trends in relation to chronological age, surgical risk, and treatment period.

Methods and results: We included 2,414 consecutive patients who underwent TAVI for severe symptomatic AS between 2008 and 2021 at 2 international centers.

Serum MMP3 and IL1-RA levels may be useful biomarkers for detecting asthma and chronic obstructive pulmonary disease overlap in patients with asthma.

Background: Asthma and chronic obstructive pulmonary disease (COPD) overlap (ACO) is characterized by concurrent features of asthma and COPD. Since disease pathogenesis, severities, and treatments differ between asthma and ACO, it is important to differentiate them.

Objective: To clarify and compare the characteristics of ACO and asthma and identify the serum biomarkers for differentiating them, especially in older patients.

Stepwise prolongation of overall survival from first to third generation EGFR-TKIs for EGFR mutation-positive non-small-cell lung cancer: the Tokushukai REAl-world Data project (TREAD 01).

Objective: The introduction of new-generation epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) has afforded promising overall survival outcomes in clinical trials for non-small-cell lung cancer. We aim to investigate the current adoption rate of these agents and the real-world impact on overall survival among institutions.

Methods: In a nationwide retrospective cohort study of 46 Tokushukai Medical Group hospitals in Japan, we analyzed clinical data of consecutive patients with non-small-cell lung cancer receiving EGFR-TKIs between April 2010 and March 2020.

Exploration of predictors associated with bleeding in computed tomography-guided core needle splenic biopsy: A retrospective study.

Splenic diseases may be caused by infections and can be either malignant, such as lymphoma and lung cancer, or benign, such as hemangioma. In some cases, diagnostic uncertainty of imaging persists, and image-guided splenic needle biopsy is a useful diagnostic tool to avoid the disadvantages of incorrect diagnosis, including performing unnecessary splenectomy or not giving the necessary treatment. Splenic biopsies can be divided into ultrasound-guided, computed tomography (CT)-guided fine-needle aspiration, or core needle biopsy (CNB).
