Compatibility of hypokalaemia caused by low-dose prednisolone plus abiraterone acetate therapy for metastatic castration-resistant prostate cancer.

Background: This study aimed to investigate the relationship between low-dose prednisolone (PSL) and the incidence of hypokalaemia at abiraterone acetate (abiraterone) plus PSL combination therapy targeting Japanese patients with metastatic castration-resistant prostate cancer (mCRPC).

Methods: This retrospective observational study included 153 Japanese patients treated with abiraterone and PSL for mCRPC at Kariya Toyota General Hospital and Gifu General Medical Center between September 2014 and October 2022. The incidence of grade ≥ 2 hypokalaemia as well as serum potassium level variations and the continuous combination therapy duration were compared between the low-dose (5 mg/day of PSL) and the standard-dose (10 mg/day of PSL) groups.

Successful pre-surgical treatment with carboplatin and gemcitabine chemotherapy for a patient with muscle-invasive bladder cancer and severe renal dysfunction.

Radical cystectomy is the standard treatment for muscle-invasive bladder cancer, and pre-surgical treatment can improve survival. Carboplatin and gemcitabine chemotherapy is considered an effective, safe treatment for patients ineligible for cisplatin-based chemotherapy owing to reduced renal function. However, there is limited evidence on pre-surgical treatment with carboplatin and gemcitabine chemotherapy with glomerular filtration rates < 30 mL/min.

Exploration of useful clinical laboratory values as diagnostic criteria for eosinophilic gastroenteritis.

Background: Eosinophilic gastroenteritis (EGE) is a rare eosinophilic infiltrative disorder. In Japan, EGE is diagnosed using clinical symptoms as well as microscopic, haematologic and histopathological findings. In this study, we examined the usefulness of laboratory data in the diagnosis of EGE.

Investigation of appropriate needle length considering skin thickness with the real injection posture for insulin injections in diabetic patients.

Background: Insulin treatment is widely used not only for type 1 but also for type 2 diabetes patients. Insulin must be injected into the subcutaneous tissue to be effective. The needle length has been shortened for safety and efficiency.

Survey of chemotherapy-induced nausea and vomiting in patients with urothelial carcinoma.

Chemotherapy-induced nausea and vomiting (CINV) can cause anorexia, weight loss and deterioration of patient quality of life. It is one of the most unpleasant adverse effects of chemotherapy treatment regimens. For the optimal treatment of gastrointestinal symptoms during urothelial carcinoma chemotherapy, the present study investigated the association between gastrointestinal symptoms and therapeutic effects of gemcitabine plus platinum [cisplatin (GC) or carboplatin (GCa)] therapies.

Diurnal Variation of Sitagliptin-Induced Pharmacological Effects in C57BL/6J Mice.

Chronopharmacology is the study of the varying responses of drugs to changes in biological timing and endogenous periodicities. The dipeptidyl peptidase-4 inhibitor sitagliptin is a globally prescribed anti-hyperglycemic drug. Although dipeptidyl peptidase-4 inhibitors are usually administered once, the specific intake time is generally not mentioned.

Chronopharmacology of dapagliflozin-induced antihyperglycemic effects in C57BL/6J mice.

Chronopharmacology is the study of the varying responses of drugs to changes in biological timing and endogenous periodicities. The selective sodium-glucose cotransporter 2 inhibitor, dapagliflozin, is a globally prescribed antihyperglycemic drug. Although dapagliflozin is usually administered once a day, the specific intake time is generally not mentioned.
