- Systematic reviews (SRs) in orthopedics need better reporting and rigorous methods to provide less biased recommendations, as assessed in a study of 360 SRs from 2012 to 2022.
- Most SRs focused on therapy-related topics, with a notable number authored by researchers from the USA, UK, and China, and only half utilized pairwise meta-analysis.
- Despite improvements in protocol registrations and risk of bias assessments by 2022, adherence to reporting guidelines was low, with poor use of comprehensive search strategies and little evaluation of evidence certainty, indicating a need for greater scrutiny by authors and reviewers.
Background: Since clinically relevant postoperative pancreatic fistula (CR-POPF) can cause intra-abdominal hemorrhage and abscesses, leading to surgery-related deaths after pancreaticoduodenectomy (PD), its preoperative prediction is important to develop strategies for surgical procedures and perioperative management. This study aimed to establish a novel prediction model for CR-POPF using preoperative markers.
Methods: On a training set of 180 patients who underwent PD at the Yamaguchi University Hospital, a combination of CR-POPF predictors were explored using the leave-one-out method with a unique discrete Bayes classifier.
Introduction: This retrospective cohort study aimed to investigate the effect of rehabilitation and without weekend therapy on Activities of daily living (ADL) and readmission in vertebral fracture patients aged 60 years and older.
Methods: The present study used a hospital-based database created by JMDC Inc. The JMDC hospital-based database is an epidemiological database that has been storing medical claims and Diagnosis Procedure Combination survey data.
Article Synopsis
- The study investigates how sleep quality in patients with chronic low back pain (CLBP) affects their quality of life (QoL), focusing on the roles of pain, cognitive factors, and central sensitization (CS).
- The research involved 101 patients and utilized structural covariance analysis to analyze data, yielding strong goodness-of-fit indices that support the model.
- Findings indicate that while sleep quality is not directly linked to QoL, it is significantly influenced by cognitive factors and CS, suggesting complex underlying relationships.

We constructed a tongue diagnosis electronic learning and evaluation system based on a standardized tongue image database.
Purpose: This study aims to verify the practicality of this assessment system by evaluating the tongue diagnosis ability of Kampo specialists (KSs), medical professionals, and students.
[Purpose] This study aimed to identify kinematic gait indicators for a fall risk screening test through quantitative comparisons of gait characteristics measured using mobile inertial sensors between faller and non-faller groups in a population of community-dwelling older people. [Participants and Methods] We enrolled 50 people aged ≥65 years who used long-term care prevention services, interviewed them to determine their fall history during the past year, and divided them into faller and non-faller groups. Gait parameters (velocity, cadence, stride length, foot height, heel strike angle, ankle joint angle, knee joint angle, and hip joint angle) were assessed using the mobile inertial sensors.
