ABSTRACT
BACKGROUND: It is reported that reduced physical activity and malnutrition may trigger pneumonia, and the utilisation of the geriatric nutritional risk index (GNRI) upon admission to long-term nursing care can enable the implementation of accurate and timely rehabilitation and nutritional support, which may, in turn, minimise pneumonia incidence. However, to date, there is no reported association between GNRI and pneumonia among stable schizophrenic patients. METHODS: This is a retrospective investigation. We enrolled 434 hospitalised subjects aged ≥50 years, who were diagnosed with stable schizophrenia between January 2017 and June 2022. Baseline nutritional status information during the stable stage of schizophrenia was evaluated using body mass index, serum albumin, and GNRI. In addition, pneumonia-based information, including diagnosis and treatment, was retrospectively obtained within 1 year. To examine the potential association between nutrition indicators and pneumonia risk among stable schizophrenia patients, we employed a logistic regression analysis. RESULTS: The pneumonia incidence among all stable schizophrenia patients was 10.14%, and there were no statistically significant difference between sexes (male vs. female, 10.63% vs. 9.44%, P = 0.687). Based on the univariate analysis of nutrition indicators and pneumonia, female patients exhibited a strong correlation between serum albumin and pneumonia (P = 0.022). Furthermore, we adjusted for potential influencing factors of pneumonia infection, and confirmed that only serum albumin was linked to pneumonia risk in female stable schizophrenia patients (odds ratio = 0.854, 95% CI: 0.749-0.975, P = 0.02). CONCLUSIONS: Based on our analysis, serum albumin was strongly correlated with pneumonia risk in female stable schizophrenia patients.

BACKGROUND: A post-marketing surveillance of blonanserin has been ongoing since September 2018. The aim of this study was to assess the effectiveness and safety of oral blonanserin in Chinese young and middle-aged female patients with schizophrenia in real clinical settings, using the data from the post-marketing surveillance. METHODS: A 12-week, prospective, multi-center, open-label, post-marketing surveillance was conducted. Female patients aged 18-40 years were included in this analysis. The Brief Psychiatric Rating Scale (BPRS) was used to evaluate the effectiveness of blonanserin in improving psychiatric symptoms. The incidence of adverse drug reactions (ADRs) such as of extrapyramidal symptoms (EPS), prolactin elevation and the weight gain were used to evaluate the safety profile of blonanserin. RESULTS: A total of 392 patients were included both in the safety and full analysis sets, 311 patients completed the surveillance protocol. The BPRS total score was 48.8 ± 14.11 at the baseline, decreasing to 25.5 ± 7.56 at 12 weeks (P < 0.001, compared with baseline). EPS (20.2%) including akathisia, tremor, dystonia, and parkinsonism were found as the most frequent ADRs. The mean weight gain was 0.27 ± 2.5 kg at 12 weeks from the baseline. Four cases (1%) of prolactin elevation were observed during the period of surveillance. CONCLUSION: Blonanserin significantly improved the symptoms of schizophrenia in female patients aged 18-40 years; the drug was well tolerated and had a low tendency to cause metabolic side effects, including prolactin elevation in these patients. Blonanserin might be a reasonable drug for the treatment of schizophrenia in young and middle-aged female patients.

BACKGROUND: Blonanserin (BNS) had been undergoing post-market surveillance (PMS) since September 2018. Using the surveillance data, we did this analysis to assess the safety and effectiveness of different doses of BNS to explore a sufficient dose range of BNS in Chinese patients with schizophrenia (SZ). METHODS: A 12-week, prospective, observational, single-arm, multicenter, open-label PMS was conducted. In this analysis, we divided the patients from PMS into low, medium to high, and high dose groups based on the dose of BNS they received, with medium to high dose group being the focus. The Brief Psychiatric Rating Scale (BPRS) scores at week 2 or 4, 6 or 8, and 12 were calculated to evaluate the effectiveness of BNS in improving psychiatric symptoms. The safety of BNS was reported as the incidence of adverse drug reactions. RESULTS: 364 patients were included in the medium to high dose group, of which 321 completed the surveillance, with a dropout rate of 11.8%. The mean daily dose was 15.1 ± 1.92 mg. The BPRS total score was 50.1 ± 11.95 at baseline and decreased to 26.6 ± 7.43 at 12 weeks (P < 0.001). When compared with other groups, the median to high dose group achieved significantly more reduction in BPRS score at week 12 (P = 0.004 versus low dose and P = 0.033 versus higher dose). Extrapyramidal symptoms [EPS (46.4%)] were the most common adverse reactions in the medium to high group. The average weight gain during the surveillance was 0.5 ± 2.56 kg and prolactin elevation occurred in 2.2% patients. Most adverse reactions were mild. CONCLUSIONS: BNS at medium to high doses (mean 15.1 mg/d) significantly improved symptoms of SZ and was well-tolerated. Most ADRs were mild, and the likelihood of causing metabolic side effects and prolactin elevations was low. Medium to high dose of BNS is a more potent treatment choice for SZ.

ABSTRACT
BACKGROUND: Internet gaming disorder (IGD) becomes a growing concern during the digital era, especially with the pandemic's social distancing measures. It is essential to comprehend the psychosocial predictors and impacts of IGD. METHODS: A two-wave annual panel study was conducted in Zigong, China, utilizing regional sampling through school-based surveys involving upper primary school to high school students. Data were collected in October 2020 (T1, N = 94,020) and October 2021 (T2, N = 60,551). Self-report data were collected on demographic information, internet gaming behavior, and other mental health factors. Cross-lagged panel models (CLPM) were employed to estimate the bidirectional relationships between the variables. RESULTS: At T1, 65,643 (72.6 %) participants identified as gamers; at T2, this number decreased to 42,213 (69.7 %). T1 IGD symptoms demonstrated predictability for all T2 psychological variables. Within the framework of the CLPM examining the interplay between IGD symptoms, anxiety symptoms, and hyperactivity/inattention, we uncovered significant reciprocal cross-lagged effects between these variables over time. The relationship between T1 IGD symptoms and T2 anxiety symptoms had age-specific differences, with 13-15-year-old boys displaying the highest coefficient, which decreased for the 16-18 age group. LIMITATIONS: Our study is subject to potential recall bias associated with self-reported retrospective data. Additionally, our analysis assumes temporal ordering between variables, an assumption that may not always hold in complex systems. CONCLUSIONS: There are reciprocal relationships between IGD symptoms, anxiety symptoms, and hyperactivity/inattention in adolescents, underscoring the imperative need for comprehensive strategies aimed at addressing the impact of IGD on mental health and overall well-being.

AIM: This study aimed to examine the link between handgrip strength (HGS) asymmetry and mortality risk among older Chinese adults. METHODS: These analyses were conducted using data from adults aged 60 years and older from the 2011-2013 waves of the China Health and Retirement Longitudinal Study, using baseline participant data collected in 2011. Proxy-reported information was used to assess the mortality outcomes of the participants over a 2-year follow-up. The highest recorded HGS values for each hand were used to compute the HGS asymmetry ratio (non-dominant HGS/dominant HGS) and HGS weakness (Male<26 kg, Female<16 kg). Covariate-adjusted Cox models were employed to gauge the relationship between abnormal HGS and mortality risk. RESULTS: Overall, 5083 adults were enrolled in this study, of whom 50.15% (2549/5083) were male. The proportions of low HGS alone, HGS asymmetry alone, and asymmetric and low HGS were 6.43%, 30.95%, and 9.22%, respectively, in males, and 4.81%, 35.87%, and 9.55%, respectively, in females. A total of 96 and 78 deaths were recorded for male (3.77%) and female (3.08%) participants, respectively, over the 2-year follow-up period. Significant differences in mortality were observed between the different HGS groups for both sexes. An adjusted Cox regression analysis model confirmed that only low HGS (P = 0.047, hazard ratio [HR] = 1.949, 95% confidence interval [95% CI]: 1.008-3.768) and low HGS with asymmetry (P = 0.007, HR = 2.152, 95% CI: 1.231-3.764) were significantly associated with mortality risk in older males. CONCLUSIONS: The results revealed that low HGS with or without asymmetry was associated with a higher risk of death over a 2-year follow-up interval in older Chinese males.

Schizophrenia is an unexplained, complex and serious mental illness. Blonanserin (BNS) is a new antipsychotic drug widely used in the treatment of schizophrenia. However, large-scale clinical studies have not been conducted in China. A multi-center, prospective, open-label, 12-week surveillance was carried out to evaluate the safety and effectiveness of BNS in patients with schizophrenia in China. Safety assessments included adverse drug reactions (ADRs), extrapyramidal symptoms (EPS), akathisia, concomitant medications for EPS by the end of treatment, and the changes in body weight from baseline by the end of treatment. The effectiveness was evaluated by the Brief Psychiatric Rating Scale (BPRS). From September 2018 to May 2020, of the 1,060 patients enrolled, 1,018 were included in the full analysis set (FAS) and safety set (SS), respectively. ADRs were developed in 205 patients among the included, the incidence being 20.1%. ADRs of EPS occurred in 169 patients, the incidence being 16.6%, ADRs of akathisia occurred in 90 patients, the incidence being 8.8%; concomitant therapeutic and prophylactic agents for EPS accounts for 19.2%; 4.0% of patients had a ≥7% increase in body weight from baseline at 12 weeks after initiating treatment. Using the last-observation-carried-forward (LOCF) method, the changes in total BPRS scores were -11.2 ± 10.17 (N = 1,018), -16.8 ± 12.69 (N = 1,018) and -20.6 ± 13.99 (N = 1,018) after 2/4, 6/8, or 12 weeks, respectively. 53.5% (545/1,018) patients showed response to blonanserin treatment in week 12. The post-marketing surveillance results of BNS demonstrates safety profile and effectiveness of the drug.
ABSTRACT
Background: Seed-based studies on resting-state functional connectivity (rsFC) in schizophrenia have shown disrupted connectivity involving a number of brain networks; however, the results have been controversial. Methods: We conducted a meta-analysis based on independent component analysis (ICA) brain templates to evaluate dysconnectivity within resting-state brain networks in patients with schizophrenia. Seventy-six rsFC studies from 70 publications with 2,588 schizophrenia patients and 2,567 healthy controls (HCs) were included in the present meta-analysis. The locations and activation effects of significant intergroup comparisons were extracted and classified based on the ICA templates. Then, multilevel kernel density analysis was used to integrate the results and control bias. Results: Compared with HCs, significant hypoconnectivities were observed between the seed regions and the areas in the auditory network (left insula), core network (right superior temporal cortex), default mode network (right medial prefrontal cortex, and left precuneus and anterior cingulate cortices), self-referential network (right superior temporal cortex), and somatomotor network (right precentral gyrus) in schizophrenia patients. No hyperconnectivity between the seed regions and any other areas within the networks was detected in patients, compared with the connectivity in HCs. Conclusions: Decreased rsFC within the self-referential network and default mode network might play fundamental roles in the malfunction of information processing, while the core network might act as a dysfunctional hub of regulation. Our meta-analysis is consistent with diffuse hypoconnectivities as a dysregulated brain network model of schizophrenia.
ABSTRACT
BACKGROUND: Relevant studies have shown that group cognitive behavioral therapy is effective in treating patients with depressive disorder, but the dropout rate is high. The present study is aimed to explore the patterns of integrated group psychotherapy. AIMS: This study investigated the clinical effects of integrated group psychotherapy for elderly patients with senile depression. METHODS: One hundred elderly patients with senile depression were divided into the experiment group (n=50) and the control group (n=50) randomly. The experiment group was given regular pharmacological treatments combined with integrated group psychotherapy, while the control group was given regular pharmacological treatments combined with integrated group cognitive behavioral therapy. These two groups were assessed with the Hamilton Depression Scale (HAMD-24) and Geriatric Depression Scale (GDS-15) before the study and at two weeks, four weeks and eight weeks after the treatments. RESULTS: According to the comparisons within these two groups, it was found that the HAMD and GDS total scores before treatments were all significantly higher than those after treatments (F=102.50, p=0.001; F=55.94, p<0.001). We found that the HAMD total scores after four weeks and eight weeks were significantly different between the two groups (F=3.82, p=0.021). The differences between two groups' GDS total scores after two weeks, four weeks and eight weeks were also significantly different (F=4.49, p=0.009). Seven cases dropped out in the experiment group, while sixteen cases dropped out in the control group. The difference of dropout rates was statistically significant (x2 =4.57, p=0.032). CONCLUSION: Medication treatments combined with the group integrated psychotherapy significantly improve the clinical effect for elderly patients with senile depression. The compliance is improved and the dropout rate declines.
