Validation of the IOTA ADNEX Model Among Japanese Women Performed by Gynecology Trainees and Ultrasound Specialists: A Retrospective Diagnostic Accuracy Study.

Objectives: This study aimed to validate the diagnostic accuracy of the International Ovarian Tumor Analysis (IOTA) Assessment of Different NEoplasias in the adneXa (ADNEX) model in Japanese women, population with a distinct adnexal mass distribution compared with European women, and to evaluate the model's utility by gynecology trainees and ultrasound specialists.

Methods: This single-center, retrospective study analyzed ultrasound data from January 2017 to March 2020 of 206 women with adnexal masses. Patients who underwent ultrasonography and serum CA-125 measurement and received postsurgery histological diagnosis were included.

Prevalence and Risk Factors of Pelvic Floor Disorders After Delivery in Japanese Women Using the Pelvic Floor Distress Inventory: A Retrospective Cohort Study.

Introduction Female pelvic floor disorders (PFDs) include clinical conditions such as urinary and fecal incontinence and pelvic organ prolapse. Disease-specific questionnaires like the Pelvic Floor Distress Inventory-20 (PFDI-20) have facilitated pelvic floor disorder assessment. We aimed to investigate the prevalence of pelvic floor disorders in Japanese women after different modes of delivery and the association of pelvic floor disorders with epidural anesthesia.

Association Between Cerebral Angiography and Asymmetrical Cortical and Deep/Medullary Vein Signs on T2 Star Magnetic Resonance Imaging in Patients with Hyperacute Horizontal Segment of the Middle Cerebral Artery Occlusion.

Background: When treating acute ischemic stroke patients, evaluation of collateral flow to the ischemic area is essential. Blood-oxygen-level-dependent imaging, including T2 star (T2∗), can identify elevated deoxyhemoglobin levels, reflecting an increase in the oxygen extraction fraction. Prominent veins on T2∗ represent increased deoxyhemoglobin and cerebral blood volume.

Prognostic value of chest computed tomography in community-acquired pneumonia patients.

Background: Chest computed tomography (CT) is commonly used to diagnose pneumonia in Japan, but its usability in terms of prognostic predictability is not obvious. We modified CURB-65 (confusion, urea >7 mmol·L, respiratory rate ≥30 breaths·min, blood pressure <90 mmHg (systolic) ≤60 mmHg (diastolic), age ≥65 years) and A-DROP scores with CT information and evaluated their ability to predict mortality in community-acquired pneumonia patients.

Methods: This study was conducted using a prospective registry of the Adult Pneumonia Study Group - Japan.

Predictive model of bleeding following endoscopic sphincterotomy for the treatment of choledocholithiasis in hemodialysis patients: A retrospective multicenter study.

Background And Aim: Although hemodialysis (HD) is a strong risk factor for postendoscopic sphincterotomy (ES) bleeding, additional risk factors in HD patients remain unclear. There is no model for predicting post-ES bleeding risk in HD patients. Therefore, we conducted a retrospective multicenter study to reveal these risk factors and develop a predictive model of post-ES bleeding in HD patients.

Automated computed tomography quantification of fibrosis predicts prognosis in combined pulmonary fibrosis and emphysema in a real-world setting: a single-centre, retrospective study.

Background: Combined pulmonary fibrosis and emphysema (CPFE) is a heterogeneous clinico-radiological syndrome without a consensus definition. There are limited data on the relation between the amount of parenchymal fibrosis and prognosis. In this study, we assessed the prognostic implications of the extent of fibrosis assessed by an automated quantitative computed tomography (CT) technique and the radiological and functional change over time in patients with a broad spectrum of fibrotic interstitial lung diseases (ILDs) encountered in a real-world setting.

Dietary trends in patients with fecal incontinence compared with the National Health and Nutrition Survey.

Objectives: Dietary guidance for patients with fecal incontinence (FI) in Japan is lacking. Here, we sought to investigate dietary trends of patients with FI.

Methods: We performed a comparative study of dietary intake par day between patients with FI and the national mean.

Impact of age on the recovery of six-minute walking distance after lung cancer surgery: a retrospective cohort study.

Purpose: The aim was to investigate the relationship of age for recovery of six-minute walking distance (6MWD), pulmonary function, and health-related quality of life (HRQOL) after lung cancer surgery.

Methods: Primary outcome was the 6MWD recovery until 6 months after surgery. Secondary outcome was the recoveries of forced expiratory volume in 1 s (FEV) and HRQOL until 6 months after surgery.

Hemodialysis is a strong risk factor for post-endoscopic sphincterotomy bleeding in patients with choledocholithiasis.

Background And Study Aims:  Hemodialysis (HD) is considered one of the risk factors for post-endoscopic sphincterotomy (ES) bleeding. Therefore, we conducted a retrospective study to evaluate HD as a risk factor for post-ES bleeding in patients with choledocholithiasis.

Patients And Methods:  We used the post-ES bleeding rate as the main outcome measure.

Survey of electric bidet toilet use among community dwelling Japanese people and correlates for an itch on the anus.

Objectives: We conducted a survey to investigate the use of bidet toilets among community dwelling Japanese people and explored the correlates for an itch on the anus.

Methods: A questionnaire-based survey was conducted among a convenience sample of individuals, who were derived from outpatients and employees of Kameda Medical Center, and students and employees of two technical colleges.

Results: A total of 4,963 respondents were evaluated in this study, 55 % of whom used bidet toilets either before or after defecation, and at least 30 % of bidet users washed the anus before defecation, partly to aid defecation.

Loop-mediated isothermal amplification method for diagnosing Pneumocystis pneumonia in HIV-uninfected immunocompromised patients with pulmonary infiltrates.

Loop-mediated isothermal amplification (LAMP) is becoming an established nucleic acid amplification method offering rapid, accurate, and cost-effective diagnosis of infectious diseases. We retrospectively evaluated 78 consecutive HIV-uninfected patients who underwent LAMP method for diagnosing Pneumocystis pneumonia (PCP). Diagnosis of PCP was made by the detection of Pneumocystis jirovecii (P.
