A Rare Case of Autoimmune-Mediated Lecithin:Cholesterol Acyltransferase Insufficiency Manifesting as the Acute Onset of Extremely Hypo-High-Density Lipoprotein-Cholesterolemia and Spontaneous Improvement: A Case Report with a Review of the Literature.

A 59-year-old Japanese woman was referred for an extremely low level of circulating high-density lipoprotein cholesterol (HDL-C). The serum HDL-C level had long been within the normal range but suddenly decreased asymptomatically to 7 mg/dL. She had no typical symptoms associated with familial lecithin, cholesterol acyltransferase deficiency (FLD), including proteinuria, anemia, and corneal opacity.

Impact of the transition from radioimmunoassay (RIA) to chemiluminescent enzyme immunoassay (CLEIA) for the measurement of plasma aldosterone concentration (PAC) on the diagnosis of primary aldosteronism (PA) via retrospective analyses in Okinawa, Japan.

In Japan, the traditional method for measuring plasma aldosterone concentration (PAC) was radioimmunoassay (RIA), which had several challenges, including poor traceability of certified reference materials and reduced detection sensitivity at low concentrations. To overcome these issues, a chemiluminescent enzyme immunoassay (CLEIA) for PAC measurement was introduced in April 2021 and the Japan Endocrine Society published new guidelines for primary aldosteronism (PA). This study aimed to evaluate the impact of the transition from RIA to CLEIA for PAC measurement on PA diagnosis.

Gut microbiota-based prediction for the transition from normal glucose tolerance (NGT) to impaired glucose tolerance (IGT) in a remote island cohort study.

Aim: The present cohort study explored whether specific gut microbiota (GM) profile would predict the development of impaired glucose tolerance (IGT) in individuals with normal glucose tolerance (NGT).

Methods: A total of 114 study subjects with NGT in Kumejima island, Japan participated in the present study and underwent 75 g oral glucose tolerance tests at baseline and one year later. We compared the profile of GM at baseline between individuals who consistently maintained NGT (NRN, n = 108) and those who transitioned from NGT to IGT (NTI, n = 6).

Post-traumatic pituitary stalk transection syndrome (PSTS) expeditiously manifested after a fall from a height combined with acute traumatic spinal cord injury: a rare case report with review of literature.

Post-traumatic pituitary stalk transection syndrome (PSTS) is an extremely rare cause of combined pituitary hormone deficiency (CPHD), affecting approximately 9 per 100,000 cases of traumatic brain injury. In contrast, pituitary stalk interruption syndrome (PSIS) is also a rare cause of CPHD. Importantly, these conditions are often confused due to their similar names and resembling findings on magnetic resonance imaging (MRI).

Profile of gut microbiota and serum metabolites associated with metabolic syndrome in a remote island most afflicted by obesity in Japan.

Numerous studies have revealed distinct differences in the profiles of gut microbiota between non-obese and obese individuals. To date, however, little is known if any disparities in the community of gut microbiota exist between metabolically healthy obese (MHO) and metabolically unhealthy obese (MUO) subjects. We therefore aimed to comprehensively characterize the gut microbiota and circulating metabolites in serum from both MHO and MUO residing in the remote island, Kumejima, where the prevalence of obesity is one of the highest in Japan, and explored possible correlations between the gut microbiota profile and markers of metabolic syndrome.

Obesity and Voiding Parameters in a Community-Based Population of Okinawa, Japan: Kumejima Digital Health Project (KDHP).

(1) Background: Evidence has accumulated regarding the etiology of lower urinary tract symptoms associated with obesity and metabolic syndrome. Therefore, the present study aimed to identify which subjectively and objectively measured voiding parameters were associated with obesity in a community-based population. (2) Methods: Voiding parameters on a self-administered questionnaire and a digital self-health monitoring system for urine excretion (s-HMSU) were compared between participants with and without obesity, defined as a body mass index ≥ 25 kg/m2 (n = 30 and 29, respectively), from a community in Okinawa, Japan.

Fermented brown rice beverage distinctively modulates the gut microbiota in Okinawans with metabolic syndrome: A randomized controlled trial.

Accumulating evidence to date suggests that brown rice is superior to white rice in regard to its beneficial impact on a number of risk factors of the metabolic syndrome (MetS). However, little is known about the influence of fermented brown rice beverage on the gut microbiota in humans. We therefore hypothesized that its impact would beneficially alter the gut microbiota composition of patients with MetS.

Effect of a mobile digital intervention to enhance physical activity in individuals with metabolic disorders on voiding patterns measured by 24-h voided volume monitoring system: Kumejima Digital Health Project (KDHP).

Purpose: To evaluate the effect of a mobile digital intervention on voiding patterns, we performed 24-h voided volume monitoring in individuals with metabolic disorders.

Methods: Participants with metabolic disorders were grouped into either the intervention group (n = 17), who had access to a smartphone app (CARADA), or the non-intervention group (n = 11), who did not. Urine monitoring was conducted for 24 h using a novel digital self-health monitoring system for urine excretion (s-HMSU).

Validation of a novel digital health monitoring system to measure the volume of voided urine.

Aim: To validate a novel digital health monitoring system to measure the volume of voided urine.

Methods: Micturition volume was calculated using our novel digital self-health monitoring system of urine excretion (s-HMSU) in 18 participants (16 women and 2 men; average age, 40.8 years), without a history of voiding symptoms.
