Medical Causes of Hospitalisation among Patients with Bronchiectasis: A Nationwide Study in Japan.

Purpose: Although the international guidelines for managing bronchiectasis are centred on preventing the exacerbation of bronchiectasis, the medical causes of admissions to hospital among patients with bronchiectasis have not been fully investigated.

Methods: This study targeted patients with bronchiectasis who were admitted to hospitals between April 2018 and March 2020 using the national inpatient database in Japan. The causes of hospitalisation and types of antibiotics used for hospitalised patients were recorded.

Feasibility of robotic-assisted surgery in advanced rectal cancer: a multicentre prospective phase II study (VITRUVIANO trial).

Background: The potential benefits of robotic-assisted compared with laparoscopic surgery for locally advanced cancer have not been sufficiently proven by prospective studies. One factor is speculated to be the lack of strict surgeon criteria. The aim of this study was to assess outcomes for robotic surgery in patients with locally advanced rectal cancer with strict surgeon experience criteria.

Interstitial Pneumonitis Following Sequential Administration of Programmed Death-1/Programmed Death-Ligand1 Inhibitors and Epidermal Growth Factor Receptor-Tyrosine Kinase Inhibitors For Non-Small Cell Lung Cancer: A Matched-Pair Cohort Study Using a Nationwide Inpatient Database.

Background: It is unclear whether the sequential administration of programmed death (PD)-1/programmed death-ligand 1 (PD-L1) inhibitors and epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) is associated with the development of severe interstitial pneumonitis (IP).

Patients And Methods: We identified 69,107 eligible patients with non-small cell lung cancer (NSCLC) from a Japanese national inpatient database, who initiated EGFR-TKI therapy. The study population was divided into the PD-1/PD-L1 inhibitor and non-prior PD-1/PD-L1 groups based on PD-1/PD-L1 administration before EGFR-TKI therapy.

Effectiveness of vortioxetine for winter depression in bipolar disorder: A case report.

Background: We present a case report on the efficacy of the short-term application of vortioxetine in managing winter depression in patients with seasonal bipolar disorder (BP). Standard treatment strategies for BP may not adequately address seasonal depressive symptoms during winter in patients with seasonal BP patterns. Depressive symptoms during winter may be linked to seasonal changes in serotonin transporter binding, such as a decrease in synaptic serotonin levels, necessitating alternative approaches.

Age-Related Differences in the Effectiveness of Rehabilitation to Improve Activities of Daily Living in Patients with Stroke: A Cross-Sectional Study.

Background: This study aimed to reveal differences in the effectiveness of rehabilitation in improving activities of daily living (ADL) in patients with acute stroke across age groups and propose age-appropriate rehabilitation strategies.

Methods: This observational study analyzed nationwide administrative data of inpatients admitted to hospitals with acute stroke between April 1, 2018, and March 31, 2020. The data included the average length of daily rehabilitation sessions, weekly frequency of rehabilitation sessions, and initiation of rehabilitation within 3 days.

Analyzing attempt and success factors for amputated digit replantation in Japan using the diagnosis procedure combination database.

The number of amputated finger replantation has declined in the USA and Germany in recent years; however, there have been no reports on recent trends in Japan. We examined the current practices, attempts, and success factors of digit replantation in Japan. We hypothesized that the rates of digit replantation and success rates were consistently standardized in Japan.

Enhancement of mineral density and mechanical properties in root caries treated with silver diammine fluoride and glass ionomer cement, with emphasis on silver ion distribution.

Objectives: This study aimed to measure the distribution of silver ion (Ag), mineral recovery, and nanohardness in carious lesions and comprehensively evaluate the degree of dentin restoration.

Methods: Sixty human teeth with root caries were randomly assigned to the control, silver diammine fluoride (SDF) [Safo], and SDF+Glass ionomer cement (GIC) treatment [Safo+Fuji] groups. Micro-computed tomography (micro-CT) was performed at five time points for each sample before/after treatment to evaluate mineral density within and around carious lesions.

Association between hospital case volume and maternal adverse events in patients with placental abruption: An analysis using a Japanese national inpatient database.

Objective: To clarify the relationship between the prognosis of patients with placental abruption (PA) and the healthcare delivery system using data from a large national inpatient database in Japan.

Methods: Using the Diagnosis Procedure Combination database, we conducted a retrospective cohort study with the data of patients in almost 1000 hospitals with the primary diagnosis of PA who were hospitalized from April 2014 to March 2021. We divided the hospitals into four groups based on the number of deliveries per month.

Analysis of the characteristics of anticipatory postural adjustments in older adults using smartphones: Association between cognitive and balance functions.

Objectives: Using smartphones, we aimed to clarify the characteristics of anticipatory postural adjustments (APA) in older adults and examine the relationship between cognitive and balance functions.

Methods: The study participants were 10 young and 13 older adults. An accelerometer built into a smartphone was attached to the lower back (L5) of the participant, and acceleration in the mediolateral direction was measured using a one-leg stance (OLS).

Association of Novel Antihyperglycemic Drugs Versus Metformin With a Decrease in Asthma Exacerbations.

Background: Similar to metformin, dipeptidyl peptidase-4 inhibitors (DPP-4 Is), glucagon-like peptidase 1 receptor agonists (GLP-1 RAs), and sodium glucose co-transporter-2 inhibitors (SGLT-2 Is) may improve control of asthma owing to their multiple potential mechanisms, including differential improvements in glycemic control, direct anti-inflammatory effects, and systemic changes in metabolism.

Objective: To investigate whether these novel antihyperglycemic drugs were associated with fewer asthma exacerbations compared with metformin in patients with asthma comorbid with type 2 diabetes.

Methods: Using a Japanese national administrative database, we constructed 3 active comparators-new user cohorts of 137,173 patients with a history of asthma starting the novel antihyperglycemic drugs and metformin between 2014 and 2022.

Association between additional weekend rehabilitation and functional outcomes in patients with hip fractures: does age affect the effectiveness of weekend rehabilitation?

Purpose: Rehabilitation after hip fracture surgery is crucial for improving physical function. Additional rehabilitation over the weekend or after working hours is reportedly associated with improved physical function; however, this may not apply to an aging population, including patients aged > 90 years. This study aimed to investigate the association between additional weekend rehabilitation and functional outcomes in different age groups.

Analysis of in-hospital deaths in patients with critical limb ischemia necessitating invasive treatments: based on a Japanese nationwide database.

Critical limb ischemia (CLI) is associated with systemic cardiovascular and non-cardiovascular diseases. Treatments primarily targeting limb-related outcomes may not improve overall life prognosis. We aimed to describe in-hospital mortality and the underlying etiologies in Japanese patients with CLI.

Clinical and molecular significance of flow cytometric analysis for reactive oxygen species production and residual p67 expression in p67-deficient chronic granulomatous disease.

Chronic granulomatous disease (CGD) is a primary immunodeficiency disease caused by molecular defects in nicotinamide adenine dinucleotide phosphate (NADPH) oxidase. p67-CGD is an autosomal recessive CGD, which is caused by a defect in the cytosolic components of NADPH oxidase, p67, encoded by NCF2. We previously established a flow cytometric analysis for p67 expression, which allows accurate assessment of residual protein expression in p67-CGD.

Noninvasive Positive Airway Pressure Management for Post-extubation Support in Preterm Infants: Observational Cohort Study with Overlap Weighting Analysis.

Background: Nasal continuous positive airway pressure (NCPAP), nasal intermittent positive pressure ventilation (NIPPV), and high-flow nasal cannula (HFNC) are often used after initial extubation in preterm infants. However, data regarding the choice between NCPAP/NIPPV and HFNC are limited. This study examined which therapy was more effective as post-extubation support.

Temporal patterns of sleep latency in central hypersomnia and attention deficit hyperactivity disorder: a cluster analysis exploration using Multiple Sleep Latency Test.

Introduction: Excessive daytime sleepiness (EDS) is a crucial symptom that diminishes the quality of life. The primary causes of EDS are central hypersomnia, including narcolepsy type 1 (NT1), type 2 (NT2), and idiopathic hypersomnia (IH). EDS is often associated with other psychiatric disorders, particularly attention deficit hyperactivity disorder (ADHD).

Impact of nurse-led interprofessional work in older patients with heart failure and multimorbidity: A retrospective cohort study.

Background: The number of patients with multimorbidity has increased due to the aging of the global population. Although the World Health Organization has indicated that multimorbidity will be a major medical problem in the future, the appropriate interventions for patients with multimorbidity are currently unknown. This study aimed to investigate whether nurse-led interprofessional work is associated with improved prognosis in heart failure patients with multimorbidity aged ≥65 years who were admitted in an acute care hospital.
