Abstract Background Approximately one-third of schizophrenia patients eventually develop treatment-resistant schizophrenia (TRS). Although the time course of TRS development varies from patient to patient, the details of these variations have not been clarified. The present study compared the duration of time required to achieve control of the first-episode psychosis (FEP) between patients who went on to develop TRS and those who did not, in order to determine whether a bifurcation point exists for the transition to TRS. Methods The present study included 271 schizophrenia patients. Based on the clinical assessment, each patient was assigned to a TRS (n = 79) or Non-TRS group (n = 182). Clinical factors relating to FEP treatment such as the duration of initial hospital admission and the degree of improvement were retrospectively identified. Results There was no significant difference in the duration of initial hospital admission (defined as the time from treatment introduction to successful discharge) between the two groups (mean of 87.9 days for TRS vs. 53.3 days for Non-TRS). The degree of improvement during initial hospital admission of the TRS group was significantly lower than that of the Non-TRS group (Global Assessment of Functioning (GAF) of 50 points for TRS vs. 61 points for Non-TRS). Approximately half of the TRS patients showed an acute onset pattern and longer hospital admission (mean 169 days) for their FEP. The other half of TRS patients needed no hospital admission, indicating an insidious onset pattern with no clear psychotic episode and treatment introduction without hospital admission. Conclusions Future TRS patients can have difficulty in improvement during their FEP. There appear to be two distinct patterns for the development of TRS. One pattern is characterized by refractory positive symptoms and a longer period to control the first psychosis; the other shows latent or insidious onset and poor response to the initial treatment.

BACKGROUNDAlthough the duration of untreated psychosis (DUP) plays an important role in the short-term prognosis of patients with schizophrenia, their long-term prognosis generally is not determined by DUP alone. It is important to explore how other clinical factors in the early stage are related to DUP and consequent disease courses.METHODSA total of 664 patients with untreated psychosis were surveyed for this study. At the first examination, we divided them into the severe positive symptoms cases (SC) or the less severe cases (NonSC) and compared the prognosis among the two groups after a 10-year follow-up. In all, 113 patients in the SC group and 43 patients in the NonSC group were follow-up completers.RESULTSWhereas DUP was not different between the two groups, patients with nonacute onset in both groups had significantly longer DUP than those in patients with acute onset. For all clinical measures, there was no difference in prognosis between the two groups or among the four groups classified by mode of onset (MoO) and initial severity of positive symptoms. However, the degree of improvement of global assessment of functioning (GAF) was significantly smaller in the NonSC-nonacute group than in the SC-acute and SC-nonacute groups.CONCLUSIONSThese results suggest that neither DUP nor MoO alone necessarily affects the initial severity of positive symptoms. Moreover, it is possible that patients with low impetus of positive symptoms onset within long DUP experience profound pathologic processes. Therefore, the current study results indicated that long DUP and nonacute onset were related to poor long-term prognosis, regardless of initial positive symptoms.

Background: The WHO’s Health Promoting Schools (HPS) framework is based on an understanding of the reciprocal relationship between health and education, and the need to take a holistic approach to health promotion in schools. We aim to clarify the degree to which the HPS framework is reflected in the national policies of eight target countries and the issues surrounding its successful implementation. Methods: Date were collected through two expert workshops with participants from eight Asian countries: Cambodia, China, Japan, Korea, Lao PDR, Nepal, the Philippines, and Thailand. In the first workshop, data collected on national policy were mapped against the HPS framework. From this, key issues were identified, and follow-up data collection was conducted in each country for a second workshop. Results: We identified a policy shift toward the HPS framework in six out of the eight countries. Neither Japan nor Korea had changed their national policy frameworks to reflect an HPS approach; however, in the latter, model pro- grams had been introduced at a local level. We identified various barriers to successful implementation, especially in relation to mental health and wellbeing. Conclusion: Given the recent shift toward the HPS approach in six out of the eight countries in this study, there is a need to conduct research to assess the impact of this framework on the health and wellbeing of students and school staff. At the same time, we call for more dialog in the context of Japan to explore the possible benefits of introducing the HPS framework into schools. [ABSTRACT FROM AUTHOR]

Assara seminivalis (Turner) (Pyralidae) was recorded from Japan for the first time. This species was reared from the seeds of Heritiera littoralis( Malvaceae) on the Iriomote-jima Is., the Ryukyus, southwestern Japan. Photographs of the adult specimens and male and female genitalia are presented, as well as some showing its larval biology. [ABSTRACT FROM AUTHOR]
