    ABSTRACT: Recent imaging studies have shown that brain morphology and neural activity during sexual arousal differ between homosexual and heterosexual men. However, functional differences in neural networks at the resting state is unknown. The study is to characterize the association of homosexual preference with measures of regional homogeneity and functional connectivity in the resting state. Participants were 26 healthy homosexual men and 26 age-matched healthy heterosexual men in whom we collected echo planar magnetic resonance imaging data in the resting state. The sexual orientation was evaluated using the Kinsey Scale. We first assessed group differences in regional homogeneity and then, taking the identified differences as seed regions, we compared groups in measures of functional connectivity from those seeds. The behavioral significances of the differences in regional homogeneity and functional connectivity were assessed by examining their associations with Kinsey Scores. Homosexual participants showed significantly reduced regional homogeneity in the left inferior occipital gyrus, right middle occipital gyrus, right superior occipital gyrus, left cuneus, right precuneus, and increased regional homogeneity in rectal gyrus, bilateral midbrain, and left temporal lobe. Regional homogeneity correlated positively with Kinsey scores in the left inferior occipital gyrus. The homosexual group also showed reduced functional connectivity between left middle temporal gyrus, left supra-marginal gyrus, right cuneus and the seed region, i.e. left inferior occipital gyrus. Additionly, the connection between the left inferior occipital gyrus and right thalamus correlated positively with Kinsey scores. These differences in regional homogeneity and functional connectivity may contribute to a better understanding of the neural basis of male sexual orientation.

    ABSTRACT: OBJECTIVE: To compare matched paliperidone-ER- and olanzapine-treated schizophrenic patients on measures of glucose and lipid metabolism. METHODS: Eighty hospitalized patients with schizophrenia (DSM-IV) were randomly assigned to treatment with paliperidone ER or olanzapine for a period of 12 weeks. At baseline and every 4 weeks, we assessed weight, subcutaneous fat, waist and hip circumferences, fasting glucose, insulin, glycohemoglobin A1, cholesterol, triglycerides, high density lipoprotein (HDL) cholesterol, low density lipoprotein (LDL) cholesterol, and prolactin. We also assessed at every time point body mass index (BMI), homeostasis insulin resistance (HOMA-IR), and homeostasis β-cell function (HOMA-B). RESULTS: Thirty-three patients randomly assigned to paliperidone ER and 23 patients randomly assigned to olanzapine groups completed the entire 12-week treatment. Within-group analyses showed that fasting measures in both groups increased for weight, BMI, waist circumferences, hip circumference, subcutaneous fat, cholesterol, triglycerides, and prolactin. In contrast, fasting glucose, LDL, and HOMA-B increased during treatment only in the olanzapine group. We also detected significantly different serum prolactin levels at all time point between the paliperidone ER- and olanzapine-treated groups, as well as a statistical trend for HOMA-B to increase more in the olanzapine compared to paliperidone-ER group over the 12 weeks of the trial. We did not detect, however, differential drug effects over the 12 weeks of the trial on fasting measures of BMI, glucose, glycohemoglobin A1, insulin, HDL, LDL, cholesterol, triglyceride, or HOMA-IR. CONCLUSION: This study reinforces the necessity of regularly monitoring metabolic parameters in patients with schizophrenia taking atypical antipsychotics, including paliperidone ER.

    ABSTRACT: The homosexual population is particularly susceptible to sexually transmitted disease because of various high-risk sexual behaviors among them. The authors explored the application of capture-recapture methods in estimating the size of the sexually active homosexual male population in Hangzhou. Homosexual men at 9 activity sites were investigated in Hangzhou, Zhejiang. The total active homosexual male population of Hangzhou estimated by the capture-recapture method and multiplier method was 2014 (95% confidence interval [CI] = 1899-2129) and 2012.5 (95% CI 1925 to 2101), respectively. This study shows that the capture-recapture method can be used to enumerate and provide accurate and reliable estimates of the active homosexual population in any area, provided that certain conditions are controlled.

    ABSTRACT: The objective of this study was to evaluate the effectiveness and tolerability of citalopram versus citalopram plus paliperidone combination therapy in patients with somatoform disorders (SDs). In this 6-week, randomized, fixed-dose study, 60 patients with SD (ICD-10 F45.0), undifferentiated SD (F45.1), and somatoform autonomic dysfunction (F45.3) were randomly assigned to receive citalopram (20 mg/day) with or without paliperidone (3 mg/day). Four scales were used to evaluate effectiveness and tolerability at baseline and at the end of the second, fourth, and sixth week after treatment: Somatoform Disorders Screening Symptoms-7 (SOMS-7), Hamilton Anxiety Scale (HAMA), 17-item Hamilton Depression Scale (HAMD-17), and Treatment Emergent Symptom Scale (TESS). The rater was blinded to the kind of treatment patients received. (i) In the intention-to-treat population (N = 51), the overall response ratio (50% reduction in SMOS-7 scores) was significantly higher in the citalopram-paliperidone group compared with the citalopram group after a 6-week treatment (71.4 vs. 38.10%, χ² = 4.71, P = 0.03). (ii) The SOMS-7 and somatic subscore of the Hamilton Anxiety Scale (HAMA-SOM) total score of the citalopram plus paliperidone group decreased more significantly than that of the citalopram group, and a significant difference could be observed at the end of 4 weeks of treatment. (iii) There was no significant difference between the two groups in adverse effects, and no serious adverse event was reported in both groups. Our findings indicate that a combination with paliperidone is significantly better than monotherapy with citalopram whether synergistic or add-on for patients with SDs. Our results call for future studies with larger sample sizes and a longer duration to draw more definitive conclusions.

    ABSTRACT: Few studies demonstrated neural circuits related to disgust were influenced by internal sexual orientation in male. Here we used fMRI to study the neural responses to disgust in homosexual and heterosexual men to investigate that issue. Thirty-two healthy male volunteers (sixteen homosexual and sixteen heterosexual) were scanned while viewing alternating blocks of three types of erotic film: heterosexual couples (F-M), male homosexual couples (M-M), and female homosexual couples (F-F) engaged in sexual activity. All the participants rated their level of disgust and sexual arousal as well. The F-F and M-M stimuli induced disgust in homosexual and heterosexual men, respectively. The common activations related to disgusting stimuli included: bilateral frontal gyrus and occipital gyrus, right middle temporal gyrus, left superior temporal gyrus, right cerebellum, and right thalamus. Homosexual men had greater neural responses in the left medial frontal gyrus than did heterosexual men to the sexual disgusting stimuli; in contrast, heterosexual men showed significantly greater activation than homosexual men in the left cuneus. ROI analysis showed that negative correlation were found between the magnitude of MRI signals in the left medial frontal gyrus and scores of disgust in homosexual subjects (p<0.05). This study indicated that there were regions in common as well as regions specific for each type of erotic stimuli during disgust of homosexual and heterosexual men.

    ABSTRACT: The present study is aimed at evaluating the efficacy and safety of long-acting risperidone on early onset schizophrenia in adolescent patients. A total of 31 adolescent patients (13 -18 years) with schizophrenia met the DSM-IV-TR criteria for schizophrenia and their symptoms were stable when orally taking risperidone or olanzapine. They were admitted into a 24 week, open-label study on the long-acting risperidone. Risperidone was administered every 2 weeks at a dose of 25, 37.5 and up to a maximum dose of 50 mg. The Positive and Negative Syndrome Scale (PANSS), the Clinical Global Impressions (CGI) and the Extrapyramidal symptom rating scale (ESRS) were used to assess the improvement in the symptoms. Improvements in the symptoms of schizophrenia occurred in patients treated with long-acting risperidone at week 6 and continued throughout the study with significant reduction in total PANSS score at week 24 (-4.2 ± 0.2, P < 0.01). At the same time, 51.6% of patients were rated as clinical improvement at the end of study. Among these 31 cases, the most frequently reported adverse events were depression (12.9%), anxiety (9.7%), headache (9.7%) and insomnia (6.4%). ESRS scores were reduced during the treatment with long-acting risperidone. The mean decrease in serum prolactin and body weight was 13.1 ng/ml and 4.5 kg, respectively. Intramuscular administration of long-acting risperidone was safe and well tolerated in adolescent patients. Long-acting risperidone also could improve the symptoms of schizophrenia in adolescent patients.
