BACKGROUND Clinical relevance of dental caries is often underestimated in patients with schizophrenia. The objective of this study was to examine dental caries and to identify clinical and demographic variables associated with poor dental condition in patients with schizophrenia. METHODS Inpatients with schizophrenia received a visual oral examination of(More)
We study tilted perfect fluid cosmological models with a constant equation of state parameter in spatially homogeneous models of Bianchi type VI −1/9 using dynamical systems methods and numerical simulations. We study models with and without vorticity, with an emphasis on their future asymptotic evolution. We show that for models with vorticity there(More)
OBJECTIVE While 65%-80% occupancy of dopamine D2 receptors with antipsychotics has been proposed to achieve optimal therapeutic response during acute treatment of schizophrenia, it remains unclear as to whether it is also necessary to maintain D2 receptor occupancy within this "safe" window for ongoing maintenance treatment. The data are especially scarce(More)
OBJECTIVE We assessed the reliability of remote video psychiatric interviews conducted via the internet using narrow and broad bandwidths. METHOD Televideo psychiatric interviews conducted with 42 in-patients with chronic schizophrenia using two bandwidths (narrow, 128 kilobits/s; broad, 2 megabits/s) were assessed in terms of agreement with face-to-face(More)
INTRODUCTION The objective of this study was to examine the evolution of antidepressant switch and adjunctive therapy. METHODS This chart review was conducted at 6 primary psychiatric clinics or hospitals, in Tokyo, Japan. A chart review of longitudinal prescriptions was conducted regarding 633 outpatients with major depressive disorder for up to 2 years(More)
Long-term follow-up data of patients with schizophrenia on depot antipsychotics have been few and the longest follow-up period has been up to 7 years. We carried out a systematic chart review to examine 10-year outcomes for outpatients with schizophrenia who were receiving a conventional depot antipsychotic. Maintenance of outpatient status for 10 years was(More)
OBJECTIVE The use of an algorithm may facilitate measurement-based treatment and result in more rational therapy. We conducted a 1-year, open-label study to compare various outcomes of algorithm-based treatment (ALGO) for schizophrenia versus treatment-as-usual (TAU), for which evidence has been very scarce. METHODS In ALGO, patients with schizophrenia(More)
