Methods: Patients who initiated clozapine treatment between July 2009 and December 2018 were included in this study.

Polypharmacy in Older Adults with Alzheimer's Disease.

The number of patients with Alzheimer's disease is increasing annually. Most of these patients are older adults with comorbid physical illnesses, which means that they are often treated with a combination of medications for the disease they have and those for Alzheimer's disease. Thus, older adults with Alzheimer's disease are potentially at risk for polypharmacy.

Low-dose acyclovir for prophylaxis of varicella-zoster virus reactivation after hematopoietic stem cell transplantation in children.

Background: Varicella-zoster virus (VZV) reactivation is a serious complication of hematopoietic stem cell transplantation (HSCT). Although low-dose acyclovir can prevent VZV reactivation after HSCT in adults, the efficacy of a dose of acyclovir lower than the recommended dose, such as 60-80 mg/kg/day in children, is unclear. In this study, we aimed to evaluate the incidence of VZV reactivation after HSCT during and after low-dose acyclovir administration for preventing VZV reactivation in children.

Anxiolytic-like effects of hochuekkito in lipopolysaccharide-treated mice involve interleukin-6 inhibition.

Hochuekkito (HET) is a Kampo medicine used to treat postoperative and post-illness general malaise and decreased motivation. HET is known to regulate immunity and modulate inflammation. However, the precise mechanism and effects of HET on inflammation-induced central nervous system disorders remain unclear.

Retrospective Cohort Study of Clinical Efficacy and Safety of Cefozopran for Treating Febrile Neutropenia during Chemotherapy in Patients with Lung Cancer.

Febrile neutropenia (FN) is a serious side effect in patients undergoing cancer chemotherapy and frequently proves fatal. Since infection control is crucial in the management of FN, the antimicrobial agent cefozopran (CZOP) has been recommended but not approved for routine use in clinical care of FN in Japan. However, few studies of CZOP in the management of FN have used a thrice daily dose schedule.

Bumetanide prevents diazepam-modified anxiety-like behavior in lipopolysaccharide-treated mice.

Benzodiazepine receptor agonists are widely prescribed therapeutic agents that alter gamma-aminobutyric acid (GABA) receptor activity and have anxiolytic effects. Post-operative use of benzodiazepines is a risk factor of delirium. Inflammatory conditions alter the anxiolytic effects of benzodiazepine.

Effects of a conventional mood stabilizer alone or in combination with second-generation antipsychotics on recurrence rate and discontinuation rate in bipolar I disorder in the maintenance phase: A systematic review and meta-analysis of randomized, placebo-controlled trials.

Objectives: A systematic review and meta-analysis of double-blind, randomized placebo-controlled trials were conducted to examine how soon an increase in recurrence risk could be observed among bipolar I disorder (BDI) patients who were clinically stable with the combination therapy of mood stabilizers with second-generation antipsychotics (SGA+MS) treatment following second-generation antipsychotics discontinuation (i.e., MS alone) compared with SGA+MS maintenance.

The Efficacy and Safety of Lubiprostone for Constipation in Cancer Patients Compared with Non-cancer Patients: A Retrospective Cohort Study.

Lubiprostone is an effective drug for various types of constipation in patients without cancer; however, there is no report on its efficacy and safety in patients with cancer. Our purpose was to evaluate the efficacy and safety of lubiprostone for constipation in cancer patients. We retrospectively studied 124 patients (cancer, N = 67) who were treated with lubiprostone for constipation in our hospital between June 2013 and May 2016.

Intracranial self-stimulation-reward or immobilization-aversion had different effects on neurite extension and the ERK pathway in neurotransmitter-sensitive mutant PC12 cells.

Various actions trigger pleasure (reward) or aversion (punishment) as emotional responses. Emotional factors that negatively affect brain neural control processes for long periods of time might cause various mental diseases by inducing neuronal changes. In the present study, newly developed PC12m12 cells which are　highly sensitivity to neurotransmitters such as acetylcholine (ACh), were used.

Recurrence of Mania or Depression Among Adult Bipolar Patients Who Continued Using Lithium: A Single-group Summary Meta-analysis of Randomized Trials.

Background: The exact recurrence rate of bipolar disorder in patients receiving lithium maintenance phase treatment and the modifiers associated with recurrence are still unknown.

Methods: We searched Embase, PubMed, and CENTRAL from inception until April 28, 2020. Outcomes included recurrence rate of any mood episode, depressive episodes, and manic/hypomanic/mixed episodes; all-cause discontinuation rate; and discontinuation rate due to adverse events.

Development of an appropriate simple suspension method for valganciclovir medication.

Background: Valganciclovir (VGC) is essential for preventing cytomegalovirus infections after transplants in adult and pediatric patients. In pediatric patients, VGC tablets have to be pulverized so that they can be delivered via nasogastric tubes. The "simple suspension method" is usually used to suspend tablets in hot water in Japan.

Efficacy and safety of lithium and lamotrigine for the maintenance treatment of clinically stable patients with bipolar disorder: A systematic review and meta-analysis of double-blind, randomized, placebo-controlled trials with an enrichment design.

Aim: Whether patients with adult bipolar disorder (BD) who have been clinically stabilized with lithium or lamotrigine should continue this medication is not established fully. This systematic review and meta-analysis evaluated the efficacy and safety of lithium and lamotrigine for maintenance treatment in clinically stable patients with adult BD.

Methods: This meta-analysis included only double-blind, randomized, placebo-controlled trials with an enrichment design that selected patients who responded acutely to lithium or lamotrigine.

Clinical characteristics of elderly depressive patients with low metaiodobenzylguanidine uptake.

Background: Recently, depression with Lewy body pathology before the appearance of parkinsonism and cognitive dysfunction has been drawing attention. Low cardiac metaiodobenzylguanidine (MIBG) uptake is helpful for early differentiation of Lewy body disease (LBD) from late-onset psychiatric disorders even before parkinsonism or dementia appears. In this study, we used MIBG uptake as a tool in suspected LBD, and evaluated the relationship of MIBG results to clinical characteristics and depressive symptoms.

Influence of lipopolysaccharide on diazepam-modified loss of righting reflex duration by pentobarbital treatment in mice.

Benzodiazepine receptor agonists are widely prescribed therapeutic agents, alter gamma-aminobutyric acid (GABA) receptor function, and have hypnotic, anxiolytic, anticonvulsant, and antispastic effects. GABA receptor activity increases under systemic inflammatory conditions. We investigated the effect of benzodiazepine receptor agonists on pentobarbital-induced loss of righting reflex (LORR) duration using a mouse model of lipopolysaccharide (LPS)-induced inflammation.

Effects of Magnesium Oxide on the Serum Duloxetine Concentration and Antidepressant-Like Effects of Duloxetine in Rats.

Duloxetine is a serotonin/noradrenaline reuptake inhibitor that is used as an antidepressant. However, it is known to cause constipation as a side effect. Magnesium compounds, such as magnesium oxide and magnesium hydroxide aqueous solution, are often combined with duloxetine to ameliorate the constipation caused by duloxetine.

[Training 5th-Year Clinical Pharmacy Students to Collect and Evaluate Information from Original Articles].

　Pharmacists are required to contribute to evidence-based medicine (EBM) by providing drug information, which can be collected from various sources such as books, websites, and original articles. In particular, information from original articles is needed in some situations. For example, original articles by international researchers are used to aid the management of novel in-hospital preparations on which little knowledge is available.

Administration of Kampo medicine through a tube at an advanced critical care center.

n emergency and critical care medical centers, tube administration is employed for patients who have difficulty swallowing oral drugs owing to decreased consciousness or mechanical ventilation. However, tube clogging due to drug injection is a concern. We compared the crushing method with the simple suspension method for the passage of amlodipine, an antihypertensive drug, in combination with rikkunshito, which has been used to treat upper gastrointestinal disorders such as functional dyspepsia and gastroesophageal reflux in emergency and critical care medical centers, to ascertain the effect of Kampo products on the passage of other drugs during tube administration.

Intracranial self-stimulation and immobilization had different effects on neurite extension and the p38 MAPK pathway in PC12m3 cells.

Aim: In mammals, rewarding and aversive states are motivational drivers of behavioral expression. However, it is unclear whether such states affect neuronal functions at the level of individual neurons. In the present study, the neuronal effects of rewarding and aversive states were investigated in using PC12 mutant cells (PC12m3 cells) with low sensitivity to nerve growth factor.

Intracranial self-stimulation-reward induces neurite extension in PC12m3 cells and activation of the p38 MAPK pathway.

Factors that trigger emotional expression may be divided into two patterns according to the type of motivation, acquiring reward (pleasure) and avoiding aversion (punishment). Repeated exposure to certain external stimuli accompanied by aberrant motivation may produce psychiatric diseases such as bipolar disorder and addiction via dysregulation of the central nervous system. However, neurobiological underpinnings of such diseases have not been clarified, especially at the neuronal level.

In vitro quantitative determination of the concentration of the polymerization agent methyl 2-benzoylbenzoate in intravenous injection solution and the cytotoxic effects of the chemical on normal human peripheral blood mononuclear cells.

In previous studies, we detected the photoinitiators 1-hydroxycyclohexyl phenyl ketone (1-HCHPK) and 2-methyl-4'-(methylthio)-2-morpholinopropiophenone (MTMP) in an intravenous injection solution. Importantly, 1-HCHPK and MTMP have been demonstrated to be cytotoxic to normal human peripheral blood (PB) mononuclear cells (MNC). Cell death (apoptosis) pathways can be classified into two modes, caspase-dependent and -independent pathways.
