Background: Clozapine is the only antipsychotic medication with proven efficacy against treatment-resistant schizophrenia. This multicenter retrospective cohort study aimed to evaluate the impact of a delay in clozapine initiation on long-term outcomes.
Methods: Patients who initiated clozapine treatment between July 2009 and December 2018 were included in this study.

Objective: To identify factors affecting adherence to medication, a subjective questionnaire survey was administered to schizophrenia patients regarding the prescribed antipsychotic formulations.
Methods: We evaluated the patients' satisfaction and dissatisfaction with prescribed antipsychotic formulations, and patients answered the Drug Attitude Inventory-10 Questionnaire (DAI-10). Inclusion criteria for patients are as follows: age between 20 and 75 years and taking antipsychotic agents containing the same ingredients and formulations, for at least 1 month.
As cognitive dysfunction due to schizophrenia is strongly associated with patients' social rehabilitation, cognitive functions have been examined as a therapeutic target. Although the Brief Assessment of Cognition in Schizophrenia (BACS) has been used to evaluate cognitive function, it is difficult to administer in routine clinical practice due to its time-consuming nature. Therefore, a novel tool is needed to facilitate the assessment of cognitive function.

For the propagation of S. aureus phages, knowledge of the effects of phage types, process parameters, and analytical methodologies should be investigated.

Objective: To improve poor medication adherence in schizophrenic patients, long-acting injectable (LAI) antipsychotics are used. However, it has not yet become common in Japan. Recently, aripiprazole LAI was approved for alternative injection into the deltoid muscle in addition to the gluteal muscle.

However, we often experience patients who require more than 2 weeks of combined use. Therefore, differences in combination periods need to be examined.

However, the DNA mutations responsible for the phenotypic change of phage resistance are unknown. Whole-genome analysis revealed eight genes that acquired mutations: six point mutations (five missense mutations and one nonsense mutation) and two deletions.

Methods: The patients enrolled in this study consisted of 10 clozapine-treated schizophrenia patients and 10 healthy adult men. A prospective, randomized, double-blind, crossover, placebo-controlled clinical trial was designed.
Blue wavelengths form the portion of the visible electromagnetic spectrum that most potently regulates circadian rhythm. We hypothesized that wearing blue-blocking (BB) glasses in the evening may influence circadian rhythm disturbances in patients with major depressive disorder (MDD), resulting in improved sleep and mood. We used a randomized placebo-controlled double-blinded design.

Unlabelled: investigated the adverse events of antipsychotics that are less likely to be reported by patients and the reasons why such symptoms remain latent.
A major factor in the resilience of is the alternative sigma factor B (σ). Type II Toxin/Antitoxin (TA) systems are also known to have a role in the bacterial stress response upon activation via the ClpP or Lon proteases. Directly upstream of the σ operon in is the TA system , which can cleave mRNA at UACMU sites.

It has been reported that clozapine-treated patients with schizophrenia and psychiatric healthcare professionals consider different side effects to be important. The aim of this study was to assess current practice related to the side effects of clozapine in clozapine-treated patients with schizophrenia and psychiatric healthcare professionals in Japan.

To increase the usability of these phages, it is necessary to understand the mechanism underlying host recognition, especially the receptor-binding proteins (RBPs) that determine host range. In this study, we found that the staphylococcal Twort-like phage ΦSA012 possesses at least two RBPs.

Objective: This study examined the utility of adenine for preventing clozapine-induced neutropenia.
Methods: This retrospective study examined the effect of adenine on clozapine-induced neutropenia in patients with treatment- resistant schizophrenia and was conducted at Okehazama Hospital in Japan from July 2010 to June 2013. Adenine was available for use from June 2011 onwards.
