Article Abstract
Background: Engaging in leisure activities was suggested to protect older adults from dementia. However, the association between playing a musical instrument and the risk of dementia is not well-established. This study aimed to investigate this association in older adults using a systematic review and meta-analysis of prospective cohort studies.
Methods: Pooled hazard ratio (HR) and 95% confidence interval (CI) of having dementia for older adults playing a musical instrument were calculated using the random-effects model. We performed the I statistic to detect heterogeneity across studies and the test for funnel plot asymmetry to assess publication bias. The risk of bias assessment was conducted using the modified Newcastle-Ottawa Scale.
Results: A total of three prospective cohort studies were found eligible: two from the U.S. and one from Japan. Playing a musical instrument, in the meta-analysis, was significantly associated with a decreased risk of dementia (HR = 0.64; 95% CI: 0.41, 0.98) among older adults. No signs of significant heterogeneity across studies (I = 23.3% and p-heterogeneity = 0.27) or publication bias (z= -1.3 and p-publication bias = 0.18) were identified.
Conclusion: Playing a musical instrument was associated with a decreased risk of dementia among older adults. Older adults should be encouraged to engage in leisure activities, especially playing musical instruments.

Introduction: Despite high coverage of routine childhood vaccines, uptake of the human papillomavirus (HPV) vaccine in the Pacific Island nation of Tonga has been slow. Culturally appropriate communication resources on the importance, safety, and effectiveness of the HPV vaccine are critical to support acceptance and uptake. To develop these resources, it is important to understand what people want to know.

Rare diseases, defined by the 2002 Rare Disease Act, affect fewer than 5 in 10,000 individuals. Rare metabolic bone diseases (MBDs), such as osteogenesis imperfecta, hypophosphatasia, osteopetrosis, and other unclassified disorders, can disrupt bone development and remodeling, posing diagnostic and management challenges. This study analyzed data from the rarembd.

The surgical approach of ureteral stricture has changed dramatically over the past 15 years with the rise of robotic upper urinary tract reconstruction. This study aimed to evaluate the outcomes of all robotic ureteral reconstructions performed at a single academic center for ureteral stricture and to assess the predictive factors of stricture recurrence. The charts of all patients who underwent robot-assisted ureteral reconstruction between 2013 and 2024 at a single academic center were retrospectively reviewed.

Objective: Reveal the changing rule of the positional relationship between the uncinate process of cervical spine and vertebral artery by measuring the relevant parameters between the uncinate process of cervical spine and vertebral artery in different age groups.
Methods: A retrospective study was conducted on 1240 cases of cervical spine imaging data from 2018 to 2021 in the Radiology Department of the Affiliated Hospital of Inner Mongolia Medical University. The distance between the uncinate process superior ridge and vertebral artery and the maximum of pedicle transverse angle, the minimum of pedicle transverse angle, the range of pedicle transverse angle and the pedicle width were measured according to age groups.

Introduction: Pituitary adenomas (PAs) are generally benign neoplasms, though in rare cases may exhibit aggressive behavior. In 2024, the PANOMEN-3 workshop released a new clinical-pathological classification. The objective of this study was to examine the potential of the PANOMEN-3 classification to predict prognosis of PAs and guide treatment in our single center cohort of patients with PAs.
