Validity of the international physical activity questionnaire short form for assessing physical activity in Japanese adults with type 1 diabetes.

Objective: To examine the validity of the International Physical Activity Questionnaire short form (IPAQ-SF) against an objective method for assessing physical activity (PA) in Japanese adults with type 1 diabetes (T1D).

Methods: This cross-sectional study included 126 adults with T1D (aged 20-74 years). The participants wore a triaxial accelerometer for 7 consecutive days and completed the IPAQ-SF (a recall survey for the last 7 days) on the day following the 7-day accelerometer period.

Association between serum zinc levels and trabecular bone scores among patients undergoing chronic hemodialysis.

Introduction: Zinc, an essential trace element, plays an important role in various cellular processes, and zinc deficiency is common in patients undergoing hemodialysis. Zinc has been shown to stimulate osteoblastic bone formation and mineralization and inhibit osteoclastic bone resorption. Although osteoporosis is highly prevalent among patients undergoing hemodialysis, the utility of areal bone mineral density (aBMD) measured using dual-energy X-ray absorptiometry (DXA) is limited because DXA cannot reveal bone microarchitectural alterations.

Who Could Be Targeted for Teledentistry in Japanese Clinics? A Questionnaire Survey of Patients.

Objectives: The COVID-19 pandemic has fostered the use of teledentistry worldwide. However, teledentistry remains underutilized in Japan due to a lack of clarity regarding its target population. This study aimed to determine the current demands of patients of dental clinics in Saitama, Japan; enable dental care professionals to adopt teledentistry; and examine which patients could be targeted for teledentistry.

Depressive Symptoms and Amyloid Pathology.

Importance: Depressive symptoms are associated with cognitive decline in older individuals. Uncertainty about underlying mechanisms hampers diagnostic and therapeutic efforts. This large-scale study aimed to elucidate the association between depressive symptoms and amyloid pathology.

Pulmonary pleomorphic carcinoma: A rare case showing arterial carcinomatosis mimicking pulmonary artery intimal sarcoma.

A male in his seventies presented with lung cancer in the right lower lobe. The surgically resected specimen revealed a pleomorphic carcinoma featuring an adenocarcinoma component with lepidic, acinar, and papillary patterns, alongside a spindle cell component spreading along the pulmonary artery wall, resembling intimal sarcoma. The spindle tumor cells were positive for keratins, TTF-1, napsin A, and vimentin, but negative for p40, CK14, desmin, alpha-smooth muscle actin, CDK4, and MDM2.
