Background: In recent years, a notable increase in syphilis cases has been observed in Japan, aligning with global trends. We aimed to elucidate the trends in sexually transmitted infections (STIs) incidence (specifically syphilis) in Japan and examine its relationship with the number of sex industry-related businesses in prefectures.

Methods: Data on STIs and the number of sex industry-related businesses from 2000 to 2022 were obtained from the National Institute of Infectious Diseases (NIID) and the official website of the Japan National Crime Prevention Association, respectively.

Article Synopsis
  • The choroid plexus plays a vital role in producing cerebrospinal fluid and regulating circadian rhythms, which can be affected by neurodegenerative diseases like Alzheimer's.
  • A study analyzed brain samples from patients with Alzheimer's, vascular dementia, Parkinson's disease, and multiple system atrophy, focusing on the morphology of choroid plexus epithelial cells.
  • Results showed no significant changes in epithelial cell measurements across the different disease groups, but age was positively correlated with cell size, suggesting that aging affects these cells regardless of neurodegenerative conditions.

  • This study investigates how air temperature affects mortality rates from the 10 leading causes of death in Japan, comparing Hokkaido (cold region) and Okinawa (warm region).
  • Data from January 2008 to December 2022 revealed that Hokkaido had significantly lower temperatures and higher death rates (excluding aspiration pneumonia) from most leading causes than Okinawa.
  • It was found that several causes of death, especially heart disease and cerebrovascular disease, were linked to temperature variations, with notable differences in the patterns observed between the two regions.

  • The CANPIONE study aimed to evaluate the effectiveness of canagliflozin, an SGLT2 inhibitor, in slowing the progression of chronic kidney disease (CKD) in participants with early-stage CKD and type 2 diabetes.
  • In a trial involving 98 participants, those taking canagliflozin showed a significant reduction in urinary albumin levels and a slower decline in their estimated glomerular filtration rate (eGFR) compared to those receiving standard treatment.
  • The study suggests that monitoring individual changes in eGFR slope could be a promising method for assessing the kidney-protective effects of new treatments in early CKD.

The number of older drivers is increasing with the aging population; this has led to concerns about traffic accidents involving older drivers. For older adults, the automobile is not just a means of transportation, but a life necessity that promotes social activities and maintains and improves health-related quality of life. In this study, we aimed to clarify the relationship between driving ability and physical fitness factors among 70 older adult drivers using a single regression analysis and multiple regression models adjusted for age, sex, and other factors.

Objective: Coronavirus infectious disease, that emerged in 2019 (COVID-19) has been a major public health issue not only in Japan, but also worldwide, and the implementation of a proper vaccination strategy has been important. To promote vaccination, the present study compared impressions of COVID-19 vaccinations stratified by the number of vaccinations among healthcare professional university students in Okayama, Japan, and suggests better vaccination strategies.

Method: A total of 212 Japanese healthcare professional university students were enrolled in this clinical qualitative study using the text mining method.

The aim of this study was to compare impressions of COVID-19 vaccination and influenza vaccination in Japan by analyzing social media (Twitter) using a text-mining method. We obtained 10,000 tweets using the keywords "corona vaccine" and "influenza vaccine" on 15 December 2022 and 19 February 2023. We then counted the number of times the words were used and listed frequency of these words by a text-mining method called KH Coder.

Article Synopsis
  • - A man in his forties was found dead at a friend's house, with toxicological analysis revealing fatal levels of caffeine and other drugs commonly found in an over-the-counter cough medicine called BRON, which is sold in Japan.
  • - The analysis showed significant concentrations of caffeine, chlorpheniramine, dihydrocodeine, and methylephedrine, with caffeine being classified as a methylxanthine and primarily metabolized by cytochrome P450 (CYP)1A2, which can be inhibited by fluvoxamine.
  • - The study concluded that his death resulted from an overdose of BRON, highlighting the need to consider drug interactions, as fluvoxamine's inhibition of caffeine metabolism likely increased his caffeine

Factors associated with dynamic changes in the objectively measured physical activity have not been well understood. We aimed to 1) evaluate the longitudinal change in the physical activity trajectory according to sex which is associated with age and to 2) determine the factors associated with the dynamic change in physical activity-related variables across a wide age range among Japanese adults. This longitudinal prospective study included 689 Japanese adults (3914 measurements) aged 26-85 years, whose physical activity data in at least two surveys were available.

Resistance training is effective in chronic hemodialysis patients with type 2 diabetes mellitus, but its effect on toe pinch force (TPF) is unknown. This study was a randomized controlled trial conducted at three hospitals to investigate the effect of short-term toe resistance training on TPF in chronic hemodialysis patients with type 2 diabetes. The patients were randomly allocated to intervention (performed aerobic exercise and four toe resistance training exercises) and control (performed aerobic exercise only) groups.

Previous cross-sectional studies have indicated that low relative appendicular lean mass (ALM) against body weight (divided by body weight, ALM/Wt, or divided by body mass index, ALM/BMI) was negatively associated with metabolic syndrome (MetS). Conversely, previous cross-sectional studies have indicated that the absolute ALM or ALM divided by squared height (ALM/Ht2) were positively associated with MetS. The aim of this longitudinal study was to investigate the association between low absolute or relative skeletal muscle mass, leg muscle power, or percent body fat and the development of MetS in Japanese women in a 7-y prospective study.

Background: In patients with systemic lupus erythematosus (SLE), a higher frequency of atherosclerotic lesions is associated with poor prognosis. Hydroxychloroquine (HCQ) has been reported to improve the lifespan and the prognosis of dyslipidaemia in patients with SLE, but the mechanism is unclear. We investigated the effect of supplemental HCQ treatment on the levels of serum cytokines associated with atherosclerosis in patients with stable SLE.
