Background: Various factors are related to self-management of medication. However, few reports comprehensively examine the factors related to patients, medication levels, and other factors related to the recuperative environment, such as family support. The aim of this study was to investigate factors affecting the continuation of medication self-management among hospitalized older adults receiving convalescent rehabilitation.

We included 1,181 officers who worked at local authorities within the urgent protective action planning zone of Sendai Nuclear Power Station in Kagoshima Prefecture, Japan. Logistic regression analysis revealed that female sex (odds ratio = 2.

However, there is a perception that scientific information about the health impact of radiation exposure has not been adequately shared among the local government staffs, including schoolteachers. We contacted schoolteachers at all 120 schools within the Urgent Protective Action Planning Zone of the Sendai Nuclear Power Plant, Kagoshima prefecture, in 2017.

Because of a few reports on Asian populations, it is unclear whether the clinical characteristics of sIBM are identical in Caucasian and Japanese patients.
Methods: We compared 18 patients with sIBM, divided into 3 groups by age-of-onset, with previous cohort studies.
Background: Nonsystemic vasculitic neuropathy (NSVN) is a vasculitis syndrome clinically restricted to the peripheral nervous system. Although treatment may improve prognosis, daily activities of such patients after treatment have not been well studied.
Methods: We evaluated clinical features, laboratory data, nerve conduction, and sural nerve biopsy findings for 16 unbiased consecutive patients with NSVN.
When cerebral infarction develops during pregnancy, treatment without adverse effects must be considered not only for the mother but also for the fetus. Because pregnant women were excluded from many clinical trials, clear treatment guidance for them is not shown in the package inserts or guidelines of many drugs. We report the case of a 35-year-old woman (gravida 3, para 2) who developed sudden onset of left visual field defect, left hemiparesis, and dysesthesia over the left forearm during her fourth month of pregnancy.

Job stress of the employees was estimated by the score for total health risk. Among the 19 divisions, two divisions showed over 120 points of mean total health risk score.

Our previous study, however, suggested that this condition may have a genetic component [Shinkai et al 2003 Am J Med Genet 119B 7-12]. Orexins, also called hypocretins, play an important role in feeding and drinking behavior.
View Article and Find Full Text PDFA number of linkage studies have previously implicated the region of chromosome 13q34 in schizophrenia. Chumakov and colleagues (2002) identified a gene complex called G72 (now termed D-amino acid oxidase activator: DAOA)/G30 in this region and performed association analyses of the DAOA/G30 as well as the D-amino-acid oxidase (DAAO) gene with schizophrenia. DAAO oxidizes D-serine, a potent activator of the N-methyl-D-aspartate (NMDA) type glutamate receptor in the human brain whereas the DAOA protein is considered an activator of DAAO.

From the viewpoints of the prevention of health impairment, accidents at work and traffic accidents, active implementation of screening for SAS in workplaces is necessary. Using a portable pulse oximeter, we conducted SAS screening for workers, who applied for the screening or who were instructed to participate by occupational physicians based on their symptoms at the time of medical check-up, in order to evaluate the effectiveness of a portable pulse oximeter as a screening device in the workplace.

It has been reported that there are alterations in BDNF levels in the brains of patients with schizophrenia. It has also been reported that transneuronal transfer of BDNF is dependent on neuronal activity, suggesting that BDNF plays an important role in neurotransmission.

Several studies, however, have suggested that there might be a genetic predisposition to polydipsia. In the present study, using a case-control sample that is independent from the previous family sample, we examined a possible association between polydipsia and functional polymorphisms in the genes of cytochrome P450 (CYP) 1A2 and 2D6, primarily important enzymes to the pharmacokinetics of antipsychotic drugs.

NAD(P)H: quinone oxidoreductase (NQO1) is an important enzyme in the human body that counteracts the oxidative stress-induced neuronal injury caused by the toxic free radicals such as dopamine-semiquinones. Taking the possible genetic predisposition to TD into account (Yassa and Ananth, 1981), the NQO1 gene is a good candidate gene that may confer increased susceptibility to TD.

However, several studies suggest there may be a genetic predisposition to polydipsia, including our previous study demonstrating familial concordance of polydipsia among first-degree relatives with schizophrenia. Antipsychotic medications may contribute to the development of polydipsia and studies show that dopamine D2 receptors are involved in drinking behaviour pathophysiology.
View Article and Find Full Text PDFObjective: Recent studies have revealed positive associations between tardive dyskinesia (TD) and genetic polymorphisms of several cytochrome P450 (CYP) subfamilies that are involved in pharmacokinetic process of antipsychotic drugs. In the present study, we analyzed the relationship between TD and two polymorphisms of the CYP1A2 gene, 734C/A and -2964G/A, in a sample of Japanese patients with schizophrenia.
Methods: We studied 199 Japanese patients with schizophrenia.
Objective: Oxidative stress such as free radical-mediated neuronal dysfunction may be involved in the pathophysiology of schizophrenia. The human glutathione peroxidase (GPX1) is a selenium-dependent enzyme, which plays an important role in the detoxification of free radicals. We therefore hypothesized that the GPX1 gene, which is located on chromosome 3p21.

We hypothesized that deranged dopamine degradation enzyme activities might be related to the susceptibility to TD through altered dopaminergic neurotransmission in the central nervous system. In the present study, we investigated the relationship between the gene polymorphisms of three dopamine degradation enzymes and TD.
View Article and Find Full Text PDFPossible involvement of oxidative stress in the pathophysiology of tardive dyskinesia (TD) has been proposed. Long-term administration of neuroleptics alters dopaminergic turnover, yielding the increase of the formation of reactive oxygen species (ROS), which may lead to TD through neuronal toxicity as a consequence of oxidative stress. In the present study, the relationship between TD and a polymorphism of the neuronal nitric oxide synthase (NOS1) gene whose reaction product, nitric oxide (NO), is involved in oxidative stress was studied in 171 Japanese patients with schizophrenia, including 41 patients meeting TD criteria.
