Clinical characteristics and results after conservative treatment or interfascicular neurolysis of 100 limbs with spontaneous anterior interosseous nerve palsy: A prospective Japanese multicenter study.

Background: Spontaneous anterior interosseous nerve (AIN) palsy is characterized by the sudden onset of upper limb pain followed by weakness of muscles mainly innervated by the AIN. Although this palsy is conventionally treated conservatively, interfascicular neurolysis to release hourglass-like fascicular constrictions has been recommended. The present study aimed to establish the clinical characteristics and treatment strategy for this condition.

Urgent Contrast-Enhanced Computed Tomography before Early Colonoscopy in the Management of Colonic Diverticular Bleeding: A Multicenter Randomized Controlled Trial.

Introduction: Contrast-enhanced computed tomography (CE-CT) has been gaining attention as an initial investigation in the management of colonic diverticular bleeding (CDB), yet the role of CE-CT other than its diagnostic yield has not been adequately clarified. We aimed to determine whether the use of urgent CE-CT improves identification of stigmata of recent hemorrhage (SRH) in subsequently performed early colonoscopy (≤24 h of arrival) or other clinical outcomes of CDB.

Methods: We conducted a randomized, open-label, controlled trial at 23 institutions in Japan.

Methylprednisolone pulse and prednisolone for intensification of primary treatment in Kawasaki disease patients at high risk of treatment resistance: a multicenter prospective cohort study.

The purpose of this study is to determine whether adding intravenous methylprednisolone pulse (IVMP) to primary adjunctive prednisolone with intravenous immunoglobulin (IVIG) improves treatment resistance and coronary artery aneurysms (CAA) in patients with Kawasaki disease (KD) with a high risk of treatment resistance. This multicenter, prospective, observational study was conducted at 28 hospitals in Japan from October 2016 to June 2020. For patients predicted to be resistant to treatment based on a Kobayashi score ≥ 5 and total bilirubin ≥ 1.

Gender Differences in Long-Term Outcomes of Young Patients Who Underwent Percutaneous Coronary Intervention: Long-Term Outcome Analysis from a Multicenter Registry in Japan.

Young patients who underwent percutaneous coronary intervention (PCI) have shown worse long-term outcomes but remain inadequately investigated. We analyzed 1,186 consecutive young patients (aged ≤55 years) from the Keio Cardiovascular PCI registry who were successfully discharged after PCI (2008 to 2019) and compared them to 5,048 older patients (aged 55 to 75 years). The primary outcome was a composite of all-cause death, acute coronary syndrome, heart failure, bleeding, stroke requiring admission, and coronary artery bypass grafting within 2 years after discharge.

Association of pre-hospital precipitating factors with short- and long-term outcomes of acute heart failure patients: A report from the WET-HF2 registry.

Background: Interest in clinical course preceding heart failure (HF) exacerbation has grown, with a greater emphasis placed on patients' clinical factors including precipitant factor (PF). Large-scale studies with precise PF documentation and temporal-outcome variation remain limited.

Methods: We reviewed prospectively collected 2412 consecutive patient-level records from a multicenter Japanese registry of hospitalized patients with HF (West Tokyo Heart Failure2 Registry: 2018-2020).

Contrast volume and in-hospital outcomes of dialysis patients undergoing percutaneous coronary intervention.

Toxicity resulting from retained contrast media may cause adverse cardiovascular outcomes (e.g., heart failure and cardiogenic shock) for dialysis patients.

Conventional medical therapy in heart failure patients eligible for the PARADIGM-HF, DAPA-HF, and SHIFT trials.

Background: Recent trials on novel heart failure (HF) treatments (angiotensin receptor-neprilysin inhibitor, sodium-glucose cotransporter 2 inhibitor, and ivabradine) emphasize the use of conventional medical therapy (angiotensin-converting enzyme inhibitors, beta-blockers [BB], and mineral corticosteroid receptor antagonists). We aimed to evaluate the prescription rate of conventional medical therapy and its association with long-term outcomes in patients eligible for recent trials.

Methods: We examined 1295 consecutive patients with HF with reduced ejection fraction (HFrEF) from a multicenter registry (WET-HF registry).

Superiority of urgent vs early endoscopic hemostasis in patients with upper gastrointestinal bleeding with high-risk stigmata.

Background: Guidelines recommend that all patients with upper gastrointestinal bleeding (UGIB) undergo endoscopy within 24 h. It is unclear whether a subgroup may benefit from an urgent intervention. We aimed to evaluate the influence of endoscopic hemostasis and urgent endoscopy on mortality in UGIB patients with high-risk stigmata (HRS).

Multifaceted Assessment of the Effects of an Eye Exercise for Presbyopia.

Exercise for presbyopia is theoretically ineffective. However, some studies have reported favorable subject responses, although the reasons were not detected. We investigated one such presbyopic exercise.

Does neoadjuvant chemotherapy have therapeutic benefit for node-positive upper tract urothelial carcinoma? Results of a multi-center cohort study.

Objective: The indications of neoadjuvant chemotherapy (NAC) for lymph node-positive upper tract urothelial carcinoma (UTUC) have not been investigated regarding improved survival outcomes. Our specific aim was to compare the clinical outcomes of clinically node-positive UTUC patients who were treated by NAC followed by radical nephroureterectomy (RNU) or upfront RNU followed by adjuvant chemotherapy (AC).

Materials And Methods: Among 966 UTUC patients, we identified 89 with clinical nodal involvement who received either NAC before RNU nor AC after upfront RNU.

Epicardial adipose tissue is associated with cardiorespiratory fitness and hemodynamics among Japanese individuals of various ages and of both sexes.

Epicardial adipose tissue may affect hemodynamics and cardiorespiratory fitness as it is a metabolically active visceral adipose tissue and a source of inflammatory bioactive substances that can substantially modulate cardiovascular morphology and function. However, the associations between epicardial adipose tissue and hemodynamics and cardiorespiratory fitness remain unclear. This cross-sectional study aimed to examine the association between epicardial adipose tissue volume and hemodynamics, and cardiorespiratory fitness among Japanese individuals of various ages and of both sexes.

Guideline adherence for radical cystectomy significantly affects survival outcomes in non-muscle-invasive bladder cancer patients.

Background: The relationship between guideline adherence for radical cystectomy of non-muscle-invasive bladder cancer and patient prognoses currently remains unclear. We investigated whether guideline adherence at the time of non-muscle-invasive bladder cancer affects the oncological outcomes of bladder cancer patients who underwent radical cystectomy.

Methods: Among 267 cTa-4N0-2M0 bladder cancer patients, 70 who underwent radical cystectomy under the non-muscle-invasive bladder cancer or muscle-invasive bladder cancer status that progressed from non-muscle-invasive bladder cancer were identified.

Risk Factors of Coronary Artery Abnormalities and Resistance to Intravenous Immunoglobulin Plus Corticosteroid Therapy in Severe Kawasaki Disease: An Analysis of Post RAISE.

Background: Coronary artery abnormalities (CAAs) still occur in patients with Kawasaki disease receiving intensified treatment with corticosteroids. We aimed to determine the risk factors of CAA development and resistance to intensified treatment in Post RAISE (Prospective Observational Study on Stratified Treatment With Immunoglobulin Plus Steroid Efficacy for Kawasaki Disease)-the largest prospective cohort of Kawasaki disease patients to date.

Methods: In Post RAISE, 2648 consecutive patients with Kawasaki disease were enrolled.

The clinicopathological characteristics of muscle-invasive bladder recurrence in upper tract urothelial carcinoma.

This study aimed to clarify the clinical characteristics and oncological outcomes of patients with upper tract urothelial carcinoma (UTUC) who developed muscle-invasive bladder cancer (MIBC) after radical nephroureterectomy (RNU). We identified 966 pTa-4N0-2M0 patients with UTUC who underwent RNU and clarified the risk factors for MIBC progression after initial intravesical recurrence (IVR). We also identified 318 patients with primary pT2-4N0-2M0 MIBC to compare the oncological outcomes with those of patients with UTUC who developed or progressed to MIBC.

Symptom Under-Recognition of Atrial Fibrillation Patients in Consideration for Catheter Ablation: A Report From the KiCS-AF Registry.

Objectives: This study sought to investigate whether symptom under-recognition is associated with the application of catheter ablation.

Background: Atrial fibrillation (AF) symptom burden is frequently under-recognized and may affect the choice of treatment strategies.

Methods: A total of 3,276 patients with AF consecutively registered in a Japanese multicenter database from 2012 to 2017 were analyzed.

The Overlap Syndrome: A Case Report of Chronic Graft-Versus-Host Disease After the Development of a Pseudomembrane.

Background: Ocular graft-versus-host disease (GVHD) is one of the most severe complications of hematopoietic stem cell transplantation. It manifests as an impairment of the ocular surface, such as severe dry eye disease, and deteriorates the recipient's visual function and quality of life. We encountered an "overlap syndrome" of ocular GVHD, which is characterized by the presence of both acute and chronic GVHD symptoms.

Efficacy and safety of darolutamide in Japanese patients with nonmetastatic castration-resistant prostate cancer: a sub-group analysis of the phase III ARAMIS trial.

Background: Darolutamide, an oral androgen receptor inhibitor, has been approved for treating nonmetastatic castration-resistant prostate cancer (nmCRPC), based on significant improvements in metastasis-free survival (MFS) in the ARAMIS clinical trial. Efficacy and safety of darolutamide in Japanese patients are reported here.

Methods: In this randomized, double-blind, placebo-controlled phase III trial, 1509 patients with nmCRPC and prostate-specific antigen (PSA) doubling time ≤ 10 months were randomized 2:1 to darolutamide 600 mg twice daily or matched placebo while continuing androgen deprivation therapy.
