Impact of technological advancements on short-term outcomes in flap reconstruction after soft tissue sarcoma resection: A retrospective comparative analysis.

Background: Soft tissue sarcomas (STS) are rare malignancies requiring extensive surgical resection, often leading to significant soft tissue defects. Flap reconstruction is crucial for restoring function and appearance. Recent reconstructive microsurgery advancements, including high-resolution indocyanine green (ICG) imaging and ultra-high-frequency ultrasonography (UHFU), have revolutionized preoperative planning and intraoperative guidance.

Basic Science and Pathogenesis.

Background: Although amyloid deposition in brain is one of the hallmark pathological features of Alzheimer's disease (AD), the upstream events and its molecular environment in AD brain remain largely unknown. Recent advances in analytical methods such as mass spectrometry can provide the cutting-edge tools to unveil the AD pathogenesis at molecular and atomic level.

Method: In order to gain the comprehensive information about AD pathology at molecular level, postmortem brain sections of AD patients were analyzed by the hybrid molecular imaging methods composed of the conventional histological analyses, matrix assisted laser desorption ionization mass spectrometry imaging (MALDI-MSI) for small molecules, laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) imaging for metals, and particle induced X-ray emission (PIXE) imaging for elements.

Thermodynamic Concentration Inequalities and Trade-Off Relations.

Thermodynamic tradeoff relations quantify the fundamental concept of "no free lunch" in the physical world, suggesting that faster and more precise physical processes come at a higher thermodynamic cost. The key elements in these trade-off relations are the thermodynamic uncertainty relation and speed limit, which are closely tied to information inequalities from which other trade-off relations are derived. Concentration inequalities are relations that complement information inequalities in statistical analyses and have been widely used in various fields.

Clinical Manifestations.

Background: The application of image recognition technology has been spreading to dementia screening. However, cognitive function fluctuates due to mental and physical conditions.

PMDA Perspective on Use of Real-World Data and Real-World Evidence as an External Control: Recent Examples and Considerations.

Recent discussions about the utilization of real-world data (RWD) and real-world evidence (RWE) have been more focused on drug development for regulatory approval rather than during the post-marketing stage. In Japan, RWD/RWE have been practically utilized as an external control for drug approval. Most cases were related to orphan diseases where the feasibility of conducting randomized controlled clinical trials was generally low.

The correlation between discrepancies in clinical and pathological T stages and overall survival in upper urinary tract urothelial carcinoma: Analysis of the hospital-based cancer registry data in Japan.

Objective: Our study assessed the correlation between discrepancies in clinical and pathological T stages and overall survival (OS) in patients with upper urinary tract urothelial carcinoma (UTUC), including renal pelvis (UCP) and ureter (UCU) carcinoma, treated with radical surgery.

Methods: We utilized data from the Japanese Hospital-Based Cancer Registry (HBCR) to identify UTUC cases (n = 2376), consisting of UCP cases (n = 1196) and UCU cases (n = 1180), diagnosed with cTa-3N0M0 between 2012 and 2013. All cases were histologically confirmed and treated solely with radical surgery, excluding any chemotherapy or radiotherapy.

Impact of correlation structure on sample size requirements of statistical methods for multiple binary outcomes: A simulation study.

Background: In randomized clinical trials, multiple-testing procedures, composite endpoints, and prioritized outcome approaches are increasingly used to analyze multiple binary outcomes. Previous studies have shown that correlations between outcomes influence their sample size requirements. Although sample size is an important factor affecting the choice of statistical methods, the power and required sample sizes of methods for analyzing multiple binary outcomes have yet to be compared under the influence of outcome correlations.

Phenotype Spectrum of TRPM3-Associated Disorders.

Objective: Monoallelic variants in the transient receptor potential melastatin-related type 3 gene (TRPM3) have been associated with neurodevelopmental manifestations, but knowledge on the clinical manifestations and treatment options is limited.

Objective: To evaluate the satisfaction, effectiveness, and usability of a telerehabilitation programme for Parkinson's disease (PD) patients.

Design: Prospective cohort study.

Subjects/patients: PD patients based on the diagnostic criteria for clinically established or probable PD published by the International Parkinson and Movement Disorder Society.

A case of choroidal metastasis from renal cell carcinoma significantly reduced by radiotherapy.

Introduction: Choroidal metastasis from renal cell carcinoma is relatively rare and unresponsive to systemic treatment.

Case Presentation: A man in his eighties with left renal cell carcinoma and pulmonary metastasis developed visual impairment in the left eye during primary treatment with ipilimumab and nivolumab followed by secondary treatment with cabozantinib. Consultation with an ophthalmologist revealed choroidal metastasis, which was subsequently treated with local radiotherapy (3 Gy × 10 Fr), resulting in a significant reduction in the metastatic lesions.

Association Between Kyphosis and Sleep Disturbance in Community-Dwelling Older Adults: The Locomotive Syndrome and Health Outcome in Aizu Cohort Study.

Purpose: Worsening sagittal alignment of the spine, particularly kyphosis, may cause difficulty in assuming a supine position, restricting sleeping posture and movement and potentially leading to sleep disturbances. However, no studies have explored the relationship between sagittal spinal alignment and sleep disturbance. This study aimed to clarify the relationship between sagittal spinal alignment and sleep disturbance.

Plasma amyloid beta biomarkers predict amyloid positivity and longitudinal clinical progression in mild cognitive impairment.

Introduction: Previous studies have examined the predictive accuracy of plasma amyloid beta (Aβ) biomarkers in clinical cohorts. However, their accuracy for predicting amyloid-positive patients in community-based cohorts is unclear. This study aimed to determine the predictive accuracy of Aβ precursor protein 669-711/Aβ1-42, Aβ1-40/1-42 and their composite biomarkers for brain amyloid deposition or the clinical progression in community-dwelling older adults with mild cognitive impairment (MCI).

Hairy vetch ( Roth), a leguminous plant with nitrogen-fixing ability, is used as a cover crop and has the potential to suppress weeds and plant diseases. The microbial composition, particularly fungal endophytes, which may be related to the beneficial functions of this crop, has not been previously studied. In this study, we analyzed the diversity and function of culturable fungal endophytes associated with hairy vetch from eight locations across Japan.

Glioblastoma, IDH-wildtype manifesting as intracranial hemorrhage: A case report highlighting the clinical utility of digital polymerase chain reaction in integrated diagnoses.

The manifestation of glioblastoma, IDH-wildtype (GB) as intracranial hemorrhage (ICH) presents diagnostic and therapeutic challenges. Molecular characteristics, including TERT promoter mutation, EGFR amplification, and chromosome 7 gain/10 loss, were incorporated to diagnose GB in the fifth edition of the World Health Organization Classification of Tumors of the Central Nervous System. When molecular analyses fail to detect low fractions of these genetic alterations, the integrated diagnosis of GB can be enigmatic.
