Background:. Health-related quality of life (HRQOL) is an important outcome indicator of healthcare that has been little studied in East Asia, where, culturally, there is greater family interdependence than in the West. We aimed to study the HRQOL of schizophrenia outpatients compared to general practice outpatients, and to examine determinants of schizophrenia HRQOL in our community. Methods:. The HRQOL of 94 schizophrenia and 90 general practice outpatients was assessed using the COOP/WONCA chart. Clinical status, demographics, medication dosages, extrapyramidal side-effects, and frequency of personal, family and social functioning were assessed using standardized questionnaires. Results:. Some 90% of schizophrenia outpatients still lived with their immediate families, and the majority were single, unemployed, and rarely engaged in social activities. They had poorer satisfaction with overall HRQOL compared to general practice outpatients. Using stepwise linear regression analysis, poorer schizophrenia overall HRQOL was predicted by dissatisfaction with and poorer participation in family relationships, dissatisfaction with emotional well-being and male gender [R2 = 0.40, p = 0.040; F(4, 5.1) = 14.3, p < 0.001]. Conclusions:. Strained family relationships appeared to be an important contributor to poorer schizophrenia HRQOL in our East Asian community. This could possibly be related to the narrowing of social-occupational functioning and its burden on the family. [ABSTRACT FROM AUTHOR]

There has been relatively little study of the longitudinal course of cognitive functioning before the onset of schizophrenia. We report scores from standardized academic examinations at ages 12 and 16 years of 30 male patients with a first episode of schizophrenia (FES) and a normal control group balanced for gender, age, parental socio–economic class and academic scores at age 12. The FES group had greater deterioration in mathematics scores and poorer educational outcome, possibly reflecting neurocognitive changes that preceded the onset of schizophrenia.

Japanese encephalitis virus (JEV) is an important arbovirus in Asia that can cause serious neurological disease. JEV is transmitted by mosquitoes in an enzootic cycle involving porcine and avian reservoirs, in which humans are accidental, dead-end hosts. JEV is currently not endemic in Singapore, after pig farming was abolished in 1992; the last known human case was reported in 2005. However, due to its location along the East-Asian Australasian Flyway (EAAF), Singapore is vulnerable to JEV re-introduction from the endemic regions. Serological and genetic evidence in the last decade suggests JEV's presence in the local fauna. In the present study, we report the genetic characterization and the first isolation of JEV from 3214 mosquito pools consisting of 41,843 Culex mosquitoes, which were trapped from April 2014 to May 2021. The findings demonstrated the presence of genotype I of JEV (n = 10), in contrast to the previous reports of the presence of genotype II of JEV in Singapore. The genetic analyses also suggested that JEV has entered Singapore on several occasions and has potentially established an enzootic cycle in the local fauna. These observations have important implications in the risk assessment and the control of Japanese encephalitis in non-endemic countries, such as Singapore, that are at risk for JEV transmission.
