Background: Severe hypoglycemia (SH) poses a significant challenge in the management of type 1 diabetes (T1D); however, the factors that offer protection other than diabetes technologies are under-studied. The primary objective of this study was to examine the association between hypoglycemia problem-solving (HPS) abilities and severe hypoglycemic events in adults with T1D using Poisson regression analysis.

Methods: In this cross-sectional study, 287 adults with T1D (mean age: 50.

Background: FreeStyle Libre uses the algorithm to calculate the sensor glucose (SG) levels. The manufacturer announced that they had changed the algorithm from the first generation (Gen. 1) to the third generation (Gen.

Aim: The Effect of Intermittent-Scanning Continuous Glucose Monitoring to Glycemic Control Including Hypoglycemia and Quality of Life of Patients with Type 1 Diabetes Mellitus (ISCHIA) study was a randomized, crossover trial that reported the decrease in time below range (TBR) by the use of intermittent-scanning continuous glucose monitoring (isCGM) combined with structured education in adults with type 1 diabetes (T1D) treated by multiple daily injections. The participants were instructed to perform frequent scanning of the isCGM sensor (10 times a day or more) and ingest sugar when impending hypoglycemia is suspected by tracking the sensor glucose levels and the trend arrow. We conducted post-hoc analysis to identify factors affecting difference in TBR (∆TBR), in time in range (∆TIR), and in time above range (∆TAR).

Objective: We previously reported the mean average relative difference (MARD) of the sensor glucose (SG) of the first-generation FreeStyle Libre with the original algorithm, an intermittent scanning continuous glucose monitoring (isCGM) device, was 15.6% in the Effect of Intermittent-Scanning Continuous Glucose Monitoring to Glycemic Control Including Hypoglycemia and Quality of Life of Patients with Type 1 Diabetes Mellitus Study (ISCHIA Study). In the present study, we aimed to further analyze its accuracy in detail by conducting a post-hoc analysis of the study.

Article Synopsis
  • * The study surveyed 233 adults with T1D, revealing that 11.6% experienced IAH, which was linked to a 5.41 times higher odds of near-miss driving incidents.
  • * Results indicated that individuals with IAH had poorer hypoglycemia problem-solving skills compared to those without, and diabetic peripheral neuropathy increased the risk of developing IAH, while continuous insulin infusion did not reduce it.

Background: Hypoglycemia in type 1 diabetes (T1D) is associated with mortality and morbidity, especially when awareness of hypoglycemia is impaired. This study aimed to investigate the protective and risk factors for impaired awareness of hypoglycemia (IAH) in adults with T1D.

Methods: This cross-sectional study enrolled 288 adults with T1D (mean age, 50.

Article Synopsis
  • This study explored how serum levels of sTREM2 might predict cognitive impairment in non-obese patients with type 2 diabetes, as dementia risk is higher for these individuals.
  • Researchers followed 166 Japanese patients over two years, assessing their cognitive function and measuring sTREM2 levels, with results indicating that higher sTREM2 levels were linked to declining cognitive scores in those with elevated HbA levels.
  • The findings suggest that managing blood sugar levels is crucial to prevent cognitive decline, and that increased sTREM2 could serve as a potential marker for cognitive issues in poorly controlled type 2 diabetes patients who are not obese.

Objective The treatment for asymptomatic primary hyperparathyroidism (PHPT) remains controversial. In 2008, the Third International Workshop on the Management of Asymptomatic PHPT proposed a set of guidelines for the management of asymptomatic PHPT. We therefore evaluated the application of the Workshop recommendations in Japanese patients with asymptomatic PHPT.

We herein report two cases involving a mother and daughter who presented with clinical features of Cushing's syndrome (CS) at 50 and 29 years of age, respectively, and were both found to have adrenocorticotropic hormone-independent adrenal adenoma. Furthermore, a new adenoma was detected in the contralateral adrenal gland in the mother 10 years after surgical treatment, when she presented with subclinical CS. The pathogenesis of this disorder, including the presence of unknown genetic abnormalities causing hereditary CS, is currently poorly understood.

Congenital combined pituitary hormone deficiency (CPHD) is associated with deficiencies of anterior pituitary hormones. PROP1 gene mutations are often responsible for CPHD, but few such cases have been reported in Japan. This study describes a 37-year-old Japanese man with CPHD, treated with hydrocortisone, testosterone, and L-thyroxine, who was evaluated for adult growth hormone deficiency (GHD).

We herein describe the case of a 47-year-old woman with pre-clinical Cushing's syndrome caused by a left adrenal adenoma, which was diagnosed 6 years after trans-sphenoidal selective removal of a pituitary adenoma for acromegaly at age 35. The patient was started on bromocriptine and then somatostatin analogues after the surgery; however, since her serum insulin-like growth factor-1 (IGF-1) values remained above the age-adjusted normal range, the treatment for acromegaly was switched from somatostatin analogues to pegvisomant (10 mg daily), before a left laparoscopic adrenalectomy. After the subsequent adrenalectomy, the dose of pegvisomant could be reduced gradually to once every 4 days without any increase in the serum IGF-1 values.

The presence of metabolic syndrome (MetS) and its individual components is related to an increased IMT. MetS and increasing numbers of individual MetS components predicted future progression of IMT. Improvement of MetS was related to smaller increases in IMT, especially in females.

Context: The molecular mechanisms by which triglycerides in lipid droplets (LDs) are synthesized, stored, and degraded need to be elucidated.

Objective: The objectives were to report siblings with neutral lipid storage disease with myopathy (NLSDM) with a novel mutation of adipose triglyceride lipase (ATGL) and determine whether the C-terminal part of ATGL containing the hydrophobic region plays a role in the interaction with LDs.

Design And Patients: Skin fibroblasts and peripheral blood leukocytes were obtained from NLSDM patients.
