BACKGROUND: A reduction in the brain-derived neurotrophic factor (BDNF) level in the brain causes depression, whereas an increase in its level has therapeutic benefits against depression. BDNF is synthesized in various peripheral tissues and transported to the brain via the peripheral circulation across the blood-brain barrier. Therefore, substances that upregulate peripheral BDNF level may be used to prevent and treat depression. Previously, we demonstrated that Citrus unshiu peel (Chinpi) and C...

BACKGROUND: Bleeding risk factors in elderly patients with atrial fibrillation undergoing percutaneous coronary intervention (PCI) are unclear and data on the use of antithrombotic drugs are lacking. We investigated the bleeding risk factors in elderly patients with atrial fibrillation undergoing PCI to help optimize antithrombotic therapy according to bleeding risk. We also investigated the association between the actual use of antithrombotic therapy and bleeding events. METHODS: A retrospective cohort study was conducted on 134 elderly patients with atrial fibrillation who underwent primary PCI at the Department of Cardiology, Showa University Fujigaoka Hospital...

BACKGROUND: Prescribing with high levels of medical appropriateness and patient satisfaction improves adherence. However, its appropriateness does not always match patient preference. Deprescription is important for ensuring the safety of medication therapy, but is not straightforward. Although successful deprescribing requires knowledge of patients' thoughts on their prescriptions and factors that influence their acceptance of deprescribing, few comprehensive studies have been conducted on this topic...

BACKGROUND: Our case is the first report showing the development of hypoglycemia following the administration of vadadustat in a patient with chronic kidney disease being treated with mitiglinide and sitagliptin, possibly due to drug-drug interaction between vadadustat and sitagliptin under the administration of mitiglinide. CASE PRESENTATION: A 72-year-old man with type 2 diabetes mellitus had received sitagliptin 50 mg once daily and mitiglinide 10 mg three times daily over the last 3 years...

BACKGROUND: In most countries barring Japan, antihypertensive drug use has been reported using the defined daily doses/1000 inhabitants/day (DID). Although DID has been shown to allow for the assessment of the number of patients treated with a particular drug, the relationship between DID and the number of patients with hypertension has not been clarified. This study aimed to clarify the relationship between antihypertensive drug use and the number of people with high blood pressure based on the National Database of Health Insurance Claims and Specific Health Checkups of Japan (NDB) open data...

BACKGROUND: Long-term care issues, specifically metabolic bone disorders, are a concern for people living with human immunodeficiency virus (PLWH) who undergo life-long antiretroviral therapy (ART). Previous clinical trials with denosumab, an anti-RANKL antibody inhibitor, have revealed its effectiveness in increasing bone mineral density (BMD) in patients with osteoporosis. However, there are limited data on adherence and effectiveness of denosumab treatment for osteoporosis in PLWH...

BACKGROUND: Methotrexate (MTX) is used to treat graft-versus-host disease (GVHD) following allogeneic hematopoietic stem cell transplantation (allo-HSCT). Recently, a case was encountered in which the blood concentration of tacrolimus (TCR) at steady state increased after intravenous MTX administration for GVHD treatment (therapeutic IV-MTX administration). Therefore, this study aimed to investigate the effect of therapeutic IV-MTX administration on the pharmacokinetics of TCR. METHODS: This single-center, retrospective, observational study included patients who underwent allo-HSCT and received therapeutic IV-MTX administration during immunosuppressive therapy with continuous intravenous infusion (CIV) of TCR from April 2004 to December 2021...

BACKGROUND: Dexamethasone (DEX) induces CYP3A activity in a concentration-dependent manner. However, no study has examined changes in the blood concentration of CYP3A substrate drugs when DEX is administered at high doses. Herein, we present a case in which tacrolimus (TAC), a typical CYP3A substrate drug, was co-administered with a chemotherapy regimen that included high-dose DEX. CASE PRESENTATION: A 71-year-old woman underwent liver transplantation for hepatocellular carcinoma 18 years prior to her inclusion in this case study...

BACKGROUND: Suvorexant and ramelteon have been presented as useful for preventing postoperative delirium. Previous studies reported on the comparison with benzodiazepine hypnotics which have been known for the risk for inducing delirium, but the comparison with patients not taking any hypnotics has not been reported yet. Therefore, we assessed the incidence rates for postoperative delirium comparing cancer patients who received preoperative combined administration with suvorexant and ramelteon and those not taking any hypnotics...

BACKGROUND: Several methods have been reported for detecting resistance genes or phenotypic testing on the day of positive blood culture in Escherichia coli or Klebsiella pneumoniae bacteremia. However, some facilities have not introduced these methods because of costs or other reasons. Toyota Kosei Hospital introduced cefpodoxime (CPDX) rapid screening on May 7, 2018, to enable early detection of third-generation cephalosporin resistance. In this study, we aimed to evaluate the effects of intervention with an Antimicrobial Stewardship Team using CPDX rapid screening...

BACKGROUND: Gastrointestinal injuries caused by nonsteroidal anti-inflammatory drugs (NSAIDs) is a serious side effect in patients with rheumatoid arthritis (RA). However, effective therapeutic strategies have yet to be established. In this study, we investigated the therapeutic effects of teprenone (TEP), a gastric mucosal protective drug, on NSAID-induced gastrointestinal injuries in rats with RA (AA rats). METHODS: Gastrointestinal injury was induced by oral administration of indomethacin (IMC), a typical NSAID...

BACKGROUND: Drug therapy is a crucial aspect of heart failure management and has been shown to reduce morbidity and mortality in heart failure patients. However, the comparative effects of these drug classes on readmission rates have not been well studied. Therefore, the aim of this study was to examine the association between different classes of heart failure drugs and 30-day readmission rates in patients with heart failure. METHOD: A multicenter, hospital-based retrospective cohort design was employed and 572 randomly selected patients with heart failure were included...

BACKGROUND: Tedizolid is an oxazolidinone anti-MRSA drug with included in the National Health Insurance Drug Price List in 2018. The effect of hemodialysis on tedizolid phosphate concentrations has been reported; pre-dialysis concentrations decreased by 10% compared to post- dialysis concentrations. However, the material of the dialysis membrane remains unknown. In addition, there have been no reports on the effects of continuous hemodiafiltration. In this study, we investigated the effects of continuous hemodiafiltration on tedizolid using two types of dialysis membranes made of different materials...

BACKGROUND: The loading dose of teicoplanin (TEIC) is recommended for implementation. However, there is significant discrepancy between the dose settings in the package insert and, in the guidelines, and the actual status of loading doses in Japan is unclear. Furthermore, TEIC causes liver injury as side effect. Although the risk of developing liver injury has not been reported to be increased following a loading dose based on the guidelines, there is a lack of reports in large populations...

BACKGROUND: We previously demonstrated that in a Japanese national university's medical faculty, overall paper publication frequency increased between 1979-1980 and 2017-2018, while original paper publication did not increase. Further, publication language changed from predominantly Japanese to English. However, whether these trends are specific to medicine or representative of other faculties remains unclear. METHODS: We diachronically analyzed annual university library-produced publication reports for four pharmaceutical and three medical units between 1979-1980 and 2019-2020, elucidating how publication frequency, type, and language medium changed...

BACKGROUND: Tedizolid is a new oxazolidinone antibiotic with high potency for the treatment of infections caused by methicillin-resistant Staphylococcus aureus and other species. CASE PRESENTATION: Two patients with osteoarthritis (women aged 79 and 73 years, cases 1 and 2, respectively) infected with S. aureus were successfully treated with tedizolid after administration of 200 mg once daily via intravenous infusion. The synovial fluid and plasma concentrations of tedizolid during surgery in case 1 at day 7 were 2...

BACKGROUND: Among Japanese pharmacists, there is a gap in their commitment to self-improvement and a possible gap in their ability to identify and solve problems. However, the factors causing this situation have not yet been clarified. This study was conducted to identify factors that influence the abilities of Japanese pharmacists to identify and solve problems, which are skills considered essential for this profession. A prior history of presenting at academic conferences was set as a surrogate outcome to clarify whether having this experience affects the factors...

BACKGROUND: In-hospital therapeutic drug monitoring (TDM) requires a suitable quantification method for target drugs from the viewpoint of precision, throughput, and testing costs. We previously developed a practical HPLC-UV platform for quantification of serum levels of various drugs. In this report, the platform was effectively applied to the quantification of patient serum levels of five different drugs by clinical professionals in our hospital during their daily work. METHODS: The residual sera of patients receiving carbamazepine (CBZ), phenytoin (PHT), lamotrigine (LTG), vancomycin (VCM), or voriconazole (VRCZ) were used in the present clinical study...

BACKGROUND: We conducted a systematic review and meta-analysis to summarize the available literature and comprehensively appraise the renal profiles of sodium-glucose cotransporter 2 inhibitors (SGLT2i) in Japanese patients with type 2 diabetes mellitus (T2DM). METHODS: The electronic databases MEDLINE, Ichushi-web, and ClinicalTrials.gov were searched for studies without language restrictions from their inception until 20 July 2023 and CENTRAL until 21 September 2021...
