Role of orexin receptors in histamine- and chloroquine-induced pruriceptive processing.

It is known that orexin peptides are involved in nociceptive processing, while little is known about the roles of these peptides in itch processing. To reveal the functions of orexin peptides in pruriceptive processing, orexin A (OX-A) and orexin B (OX-B) were applied before histamine or chloroquine (CQ). The administration of OX-A reduced the numbers of scratching events and c-Fos positive cells induced by histamine and CQ, but not OX-B.

Rapid Identification of Fusion in Acute Lymphoblastic Leukemia.

Introduction: is rearranged and overexpressed in a subgroup of acute lymphoblastic leukemia (ALL) with B-precursor phenotype, with a favorable outcome. Even though characteristic gene expression signature as well as surface expression of CD2/CD371 could be a hallmark of -rearranged ALL, actual detection of rearrangement is, however, largely dependent on whole transcriptome analysis due to the highly repetitive nature of gene loci and insertion as the main mechanism of fusion gene formation.

Methods: Polymerase chain reactions (PCRs) with several combinations of multiplex primers located on and gene loci were used for the detection of , which represents more than 90% of fusion.

Characteristics of psychiatric patients with nightmares after suvorexant administration: A retrospective study.

Aim: Suvorexant is an orexin receptor antagonist (ORA) for the treatment of insomnia. The antagonistic action of suvorexant on orexin receptors is associated with an increase in rapid eye movement (REM) sleep, which can potentially lead to nightmares depending on the patient's condition. However, the precise risk factors for nightmares among patients taking ORAs, such as suvorexant, have yet to be identified.

Brief Behavioral Activation Intervention for Inpatient Depression by Psychiatric Nurses: A Single-Group Study.

Introduction: Behavioral Activation (BA) is a short-term cognitive behavioral therapy modality that stimulates activities that increase patients' reinforcement experiences. Recent research verified the effect of brief BA. However, despite the short intervention time per session, BA is difficult to implement during hospitalization due to its long implementation period.

Development of radioiodine-labeled mequitazine for evaluation of hepatic CYP2D activity.

As drug-metabolizing enzyme activities are affected by a variety of factors, such as drug-drug interactions, a method to evaluate drug-metabolizing enzyme activities in real time is needed. In this study, we developed a novel SPECT imaging probe for evaluation of hepatic CYP2D activity. Iodine-123- and 125-labeled 4-iodobenzylmequitazine (I-BMQ) was synthesized with high labeling and purity.

[Importance of Secondary Cancer Screening-In the Case of Childhood Cancer].

The cumulative incidence of secondary cancers in childhood cancer survivors at 20 years after treatment is 2-5%, which is 3-20 times higher than in the general population. Risk factors include radiation therapy, alkylating agents, platinum drugs, and topoisomerase Ⅱ inhibitors. A retrospective cohort study of 15 pediatric oncology hospitals in Japan revealed that the time to development of a second cancer varies from 5 years or less for hematologic tumors, 10 years or less for bone/soft tissue tumors, approximately 10 years for brain tumors, and 15-20 years for thyroid and adult-type cancers.

Differential Contribution of 5-HT, 5-HT, and 5-HT Receptors to Acute Pruriceptive Processing Induced by Chloroquine and Histamine in Mice.

The involvement of serotonin (5-HT) and/or noradrenaline in acute pruriceptive processing in the central nervous system (CNS) has been reported using antidepressants, such as milnacipran, a serotonin and noradrenaline reuptake inhibitor, and mirtazapine, a noradrenergic and specific serotonergic antidepressant; however, the roles of 5-HT receptor family in acute pruriceptive processing have not been fully elucidated in the CNS. In the present study, scratching behavior induced by chloroquine (CQ) was ameliorated by milnacipran or mirtazapine, and these effects were reversed by SB207266, a 5-HT antagonist, or SB258585, a 5-HT antagonist, but not by SB258585, a 5-HT antagonist. Moreover, CQ-induced scratches were mitigated by intrathecal injection of 5-HT agonists, such as BIMU8 and ML10302, and the 5-HT agonist, WAY208466.

Role of kainate receptors in pruriceptive processing in the mouse spinal cord.

Pruritus, including neuropathic and psychogenic pruritus, is an unpleasant feeling that causes a desire to scratch, which negatively impacts physical and psychological aspects of daily life. Nonetheless, little is known about the neural mechanisms involved in pruritus. Glutamate is a predominant excitatory neurotransmitter in the mammalian central nervous system and exerts its effects by binding to various glutamate receptors, including kainate (KA) receptors; however, the precise involvement of each glutamate receptor in pruriceptive processing remains unclear, particularly that of KA receptors.

A case study of the utilization of clozapine treatment for treatment-resistant schizophrenia associated with 22q11.2 deletion syndrome.

Background: The optimal treatment strategy for patients with treatment-resistant schizophrenia (TRS) associated with 22q11.2 deletion syndrome (DS) remains a subject of debate.

Case Presentation: We present the case of a 40-year-old female patient diagnosed with TRS and 22q11.

Frailty Improvement by Multicomponent Drug, Ninjin'Yoeito, in Mild Cognitive Impairment and Mild Alzheimer's Disease Patients: An Open-Label Exploratory Study (FRAMINGO).

Background: Alzheimer's disease (AD) and dementia have increasingly been conceived of as "complex diseases of aging", determined by multiple, simultaneous, interacting pathophysiological processes. The condition known as frailty is a phenotype of aging and its comprehensive pathophysiology is thought to be closely related to the incidence of mild cognitive impairment (MCI) and the exacerbation of dementia.

Objective: This study aimed to investigate the effect of the multicomponent drug, ninjin'yoeito (NYT), on frailty in MCI and mild AD patients.

Factors associated with employment status among mothers of survivors of childhood cancer: a cross-sectional study.

Purpose: To identify the factors associated with employment status among mothers of childhood cancer survivors (CCSs).

Methods: We conducted a questionnaire survey on mothers of survivors of childhood cancer to clarify practical factors such as care demands, psychological factors such as motivation to work, and support. After calculating descriptive statistics for all variables, binary logistic regression analysis was performed.

Characteristics of psychiatric patients with hypokalemia after yokukansan administration: A retrospective study.

Aim: Yokukansan is a Japanese herbal medicine used in psychiatry to treat behavioral and psychological symptoms of dementia and other psychiatric symptoms. However, the glycyrrhizic acid included in this medicine can cause pseudoaldosteronism and hypokalemia. We aimed to identify the risk factors for hypokalemia due to yokukansan.

Factors related to employment in childhood cancer survivors in Japan: A preliminary study.

Purpose: Previous research has revealed vocational and academic difficulties in childhood cancer survivors, and explored impact of survivors' medical history and physical function on vocational and academic status. However, we often encounter survivors with similar diagnoses and late effects but different academic or employment statuses. This raises the question of what affects academic attainment and employment other than treatment or late effects.

A nationwide survey of late effects in survivors of juvenile myelomonocytic leukemia in Japan.

We conducted a cross-sectional study using a questionnaire to explore the late effects in survivors of allogenic hematopoietic stem cell transplantation (HSCT) for juvenile myelomonocytic leukemia (JMML). The attending pediatric hematologists/oncologists completed the questionnaires. Of the 30 survivors, approximately 83% showed more than one late effect.

Significance of active screening for detection of health problems in childhood cancer survivors.

Background: Childhood cancer survivors (CCSs) have a lifelong increased risk of chronic health problems, most of which are associated with the curative therapies. Recent studies have suggested that prospective active screening using comprehensive assessments for CCSs is superior in identifying undiagnosed chronic health problems.

Methods: To assess the significance of active screening using comprehensive medical examinations for detecting chronic health problems in multiple organ systems in CCSs, we retrospectively compared the frequency and severity of health problems between two different cohorts of CCSs in a single institution: 110 CCSs who visited the outpatient clinic for regular follow-ups between December 2010 and December 2015 (regular follow-up group) vs.

Measurement of Hepatic CYP3A4 and 2D6 Activity Using Radioiodine-Labeled -Desmethylvenlafaxine.

Drug metabolizing enzyme activity is affected by various factors such as drug-drug interactions, and a method to quantify drug metabolizing enzyme activity in real time is needed. In this study, we developed a novel radiopharmaceutical for quantitative imaging to estimate hepatic CYP3A4 and CYP2D6 activity. Iodine-123- and 125-labeled -desmethylvenlafaxine (I-ODV) was obtained with high labeling and purity, and its metabolism was found to strongly involve CYP3A4 and CYP2D6.

Serum thymus and activation-regulated chemokine (TARC) levels correlate with atopic dermatitis disease severity in patients < 6 months.

Atopic dermatitis (AD) may develop by 6 months of age, and its severity assessment is essential for appropriate treatments. Scoring Atopic Dermatitis (SCORAD) is suggested to evaluate the severity of AD but is cumbersome for routine clinical use. The serum thymus and activation-regulated chemokine (TARC) is used as a marker of AD severity.

Karnofsky performance status and visual analogue scale scores are simple indicators for quality of life in long-term AYA survivors who received allogeneic hematopoietic stem cells transplantation in childhood.

The purpose of this study was to investigate Karnofsky performance status (KPS) scores and visual analogue scale (VAS) scores to explain which domains in the standardized self-reported quality of life (QOL) are instrumental for long-term hematopoietic stem cell transplantation (HSCT) survivors. We conducted a nationwide cross-sectional questionnaire study on 221 survivors with allogeneic-HSCT in 28 pediatric centers. Patient-reported QOL was assessed at a single time point using the 36-item Short-Form Survey (SF-36), the Functional Assessment of Cancer Therapy-Bone Marrow Transplant (FACT-BMT), and VAS scores.

Hospital Support for Siblings of Children With Illness in Japan.

Recent years have seen increased attention to the needs and support of siblings of children with chronic illness, and reports of intervention studies on siblings are gradually increasing worldwide. In Japan, the basic policy approved by the Cabinet in 2021 of The Basic Law for Child and Maternal Health and Development stipulates promoting support for the siblings of children with chronic illness, medical care, and disabilities. Simultaneously, practical reports are emerging.

Psychosocial interventions for community-dwelling individuals with schizophrenia: study protocol for a systematic review and meta-analysis.

Introduction: Despite the recent global mental health movement of the transition from hospital-centred to integrated community-based services, comprehensive evidence of psychosocial interventions focusing on community-dwelling individuals with schizophrenia is still lacking. To overcome this gap in the current knowledge, we will conduct a systematic review and meta-analysis to assess the efficacy of all types of psychosocial interventions for community-dwelling (non-hospitalised) individuals with schizophrenia when compared with non-active control conditions (eg, treatment as usual).

Methods And Analysis: This study protocol has been developed according to the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols guidelines.

Case of reversible Mobitz type II atrioventricular block after the use of injectable antipsychotics.

Although Mobitz type II atrioventricular block is typically an arrhythmia arising from a permanent organic disorder of the His-Purkinje system, reversible factors should also be considered. Here, we report the association between a rare reversible Mobitz type II atrioventricular block and antipsychotic medication in a 75-year-old patient with schizophrenia.
