1.Exercise therapy for diabetes mellitus
Journal of the Korean Medical Association 2023;66(7):427-431
Exercise lowers blood glucose levels, improves insulin sensitivity, and helps prevent complications; therefore, it is highly effective for prevention and treatment of diabetes mellitus. However, many patients with diabetes do not meet the recommendations for the amount of exercise. In this study, we focus on the latest recommendations and discuss exercise therapies that are helpful for patients with diabetes.Current Concepts: Many studies have shown that exercise helps to improve blood glucose control, physical strength, and cardiorespiratory capacity in patients with type 1 or 2 diabetes. Patients with diabetes are advised to perform both aerobic and resistance exercises. Aerobic exercise is suitable for most patients and can rapidly lower blood glucose levels. Resistance exercise improves muscle strength and endurance and is useful for long-term stabilization of blood glucose levels. Combined aerobic and resistance exercise improves insulin resistance and additionally controls blood glucose levels. Patients with diabetes are recommended moderate intensity exercise for at least 150 min/week, at least thrice a week, without interruption in exercise for >2 consecutive days.Discussion and Conclusion: Exercise is an essential recommended lifestyle intervention for patients with diabetes, and regular exercise is important. Furthermore, patients with diabetes should avoid low-energy activities and minimize sitting time.

Journal of Korean Medical Science 2025;40(10):e15-
Background:
Researchers have proposed that there is a potential link between folliclestimulating hormone (FSH) and cognitive function, yet the evidence remains inconclusive.The current study aims to identify the association between serum FSH levels and cognitive performance, and to examine whether this association varies by cognitive diagnosis, serum estradiol (E2) levels, or cognitive domain.
Methods:
This multicenter cross-sectional study used a clinical database comprising female visitors to memory clinics at three referral hospitals in Korea. Venous blood samples were collected to determine serum FSH and E2 concentrations via immunoradiometric assay.Cognitive performance was evaluated using either the Korean version of the Consortium to Establish a Registry for Alzheimer’s Disease or the Seoul Neuropsychological Screening Battery, while cognitive diagnoses were made via clinical diagnostic interviews.
Results:
Among the 159 participants (normal cognition [NC], n = 70; mild cognitive impairment [MCI], n = 52; Alzheimer’s disease [AD] dementia, n = 37), there were no significant differences in serum FSH levels associated with cognitive diagnosis. In women with NC, serum FSH levels were found to be positively correlated with cognitive performance in global cognition, nonverbal memory, and executive function, even after adjusting for serum E2 level and its interaction with serum FSH level. However, no significant correlations were observed in women with MCI and AD dementia.
Conclusion
The association between circulating FSH and cognition may be independent from circulating E2, but it may depend on disease progression or cognitive domains. This suggests a potential role of gonadotropin in cognitive decline in elderly women.

7.The Effect of Denosumab on Bone Mass in Super Elderly Patients
Journal of Bone Metabolism 2020;27(2):119-124
Background:
Denosumab is a potent antiresorptive drug leading to significant reduction in the risk of vertebral and non-vertebral fractures in postmenopausal osteoporosis. The effect of denosumab in super-elderly patients lacks data to date and few literature has proven the efficacy to this specific group. The purpose of this study was to determine the effectiveness and safety of denosumab in the super-elderly.
Methods:
We retrospectively evaluated 60 patients older than 80 with osteoporosis treated with denosumab. Patients were treated with denosumab every 6 months for 12 months 2017 to 2020. The primary endpoint was defined by the changes in bone mineral density (BMD) of 3 measurement sites: the lumbar spine, femoral neck, and total hip. Changes in bone turnover markers, serum calcium, serum phosphate, and 25-hydroxy-vitamin D were also observed.
Results:
All 60 patients were female, and the mean age was 83.9±3.1, from age 80 to 94. After 12 months of denosumab treatment, significant increases in BMD were observed; 3.02±2.74% for the lumbar spine (P=0.000), 3.10±6.90% for the femoral neck (P=0.005), and 2.89±5.80% for the total hip (P=0.002) The bone turnover marker C-terminal telopeptide of type I collagen and osteocalcin significantly declined after 12 months of treatment (-34.8±45.9%; P=0.002 and –35.5±38.9%; P=0.004 respectively). Symptomatic hypocalcemia and serious adverse drug reactions that required drug discontinuation were not observed during treatment.
Conclusions
Denosumab is thought to be an anti-osteoporotic medication that is sufficiently effective and safe even for the super-elderly.

Small cell lung cancer (SCLC), which originated from neuroendocrine tissue, can develop into paraneoplastic endocrine syndromes, such as Cushing syndrome, because of an inappropriate secretion of ectopic adrenocorticotropic hormone (ACTH). This paraneoplastic syndrome is known to be a poor prognostic factor in SCLC. The reason for poor survival may be because of a higher risk of infection associated with hypercortisolemia. Therefore, early detection and appropriate treatment for this syndrome is necessary. But the diagnosis is challenging and the source of ACTH production can be difficult to identify. We report a 69-year-old male patient who had severe hypokalemia, metabolic alkalosis, and hypertension as manifestations of an ACTH-secreting small cell carcinoma of the lung. He was treated with ketoconazole and spironolactone to control the ACTH dependent Cushing syndrome. He survived for 15 months after chemotherapy, which is unusual considering the poor outcome of the ectopic ATH syndrome associated with SCLC.
