Microbleeds in fronto-subcortical circuits are predictive of dementia conversion in patients with vascular cognitive impairment but no dementia

Cerebral small vessel disease(CSVD) is a common etiology of vascular cognitive impairment with no dementia(V-CIND). Studies have revealed that cerebral microbleeds(CMBs), a feature of CSVD, contribute to cognitive impairment. However, the association between CMBs and dementia conversion in individuals with V-CIND is still unclear. Here, we analyzed the predictive role of CMBs in the conversion from V-CIND to dementia in CSVD patients. We recruited and prospectively assessed 85 patients with CSVD and V-CIND. V-CIND was evaluated using a series of comprehensive neuropsychological scales, including the Chinese version of the Montreal Cognitive Assessment and the Clinical Dementia Rating. MRI assessments were used to quantify lacunar infarcts, white matter hyperintensities, CMBs, and medial temporal lobe atrophy. Eighty-two of the 85 patients completed the assessment for dementia conversion at a 1-year follow-up assessment. Multivariate logistic regression analyses were conducted to examine independent clinical and MRI variables associated with dementia conversion. Twenty-four patients(29.3%) had converted to dementia at the 1-year follow-up, and these individuals had significantly more CMBs in the fronto-subcortical circuits. Multivariate logistic regression analyses revealed that the patients with CMBs in the fronto-subcortical circuits(odds ratio = 4.4; 95% confidence interval: 1.602–12.081, P = 0.004) and 5 or more CMBs overall(odds ratio = 17.6, 95% confidence interval: 3.23–95.84, P = 0.001) had a significantly increased risk of dementia at the 1-year follow-up. These findings indicate that CMBs in the fronto-subcortical circuits may be predictive of dementia conversion in CSVD patients with V-CIND, and thus extend the clinical significance of CMBs.

Adjunctive aripiprazole for antipsychotic-related hyperprolactinaemia in patients with first-episode schizophrenia:a metaanalysis

Background Hyperprolactinaemia is a common antipsychotic(AP)-induced adverse effect,particularly in female patients.Aims This meta-analysis examined the efficacy and safety of adjunctive aripiprazole in preventing AP-related hyperprolactinaemia in patients with first-episode schizophrenia.Methods PubMed,PsycINFO,EMBASE,Cochrane Library,WanFang and China Journal Net databases were searched to identify eligible randomised controlled trials(RCTs).Primary outcomes were the reductions of serum prolactin level and prolactin-related symptoms.Data were independently extracted by two reviewers and analysed using RevMan(V.5.3).Weighted/standardised mean differences(WMDs/SMDs)±95%Cis were reported.Results In the five RCTs(n=400),the adjunctive aripiprazole(n=197)and the control groups(n=203)with a mean of 11.2 weeks of treatment duration were compared.The aripiprazole group had a significantly lower endpoint serum prolactin level in all patients(five RCTs,n=385;WMD:-50.43 ng/mL(95%Cl:-75.05 to-25.81),p<0.00001;l2=99%),female patients(two RCTs,n=186;WMD:-22.58 ng/mL(95%Cl:-25.67 to-19.49),p<0.00001;l2=0%)and male patients(two RCTs,n=127;WMD:-68.80 ng/mL(95%Cl:-100.11 to-37.49),p<0.0001).In the sensitivity analysis for the endpoint serum prolactin level in all patients,the findings remained significant(p<0.00001;l2=96%).The aripiprazole group was s叩erior to the control group in improving negative symptoms as assessed by the Positive and Negative Syndrome Scale(three RCTs,n=213;SMD:-0.51(95%Cl:-0.79 to-0.24),p=0.0002;l2=0%).Adverse effects and discontinuation rates were similar between the two groups.Conclusions Adjunctive aripiprazole appears to be associated with reduced AP-induced hyperprolactinaemia and improved prolactin-related symptoms in first-episode schizophrenia.Further studies with large sample sizes are needed to confirm these findings.

Adjunctive Peony-Glycyrrhiza decoction for antipsychotic-induced hyperprolactinaemia:a meta-analysis of randomised controlled trials

Background Hyperprolactinaemia is a common adverse effect of antipsychotics(APs). The results of PeonyGlycyrrhiza decoction(PGD) as a potentially useful adjunctive treatment for hyperprolactinaemia are inconsistent.Aim This meta-analysis of randomised controlled trials(RCTs) examined the efficacy and safety of adjunctive PGD therapy for AP-induced hyperprolactinaemia.Methods English(PubMed, Embase, Cochrane Library,PsycINFO) and Chinese(Chinese National Knowledge Infrastructure, Wanfang Data) databases were systematically searched up to 10 June 2018. The inclusion criteria were based on PIC0 S一/^rticipants: adult patients with schizophrenia; Aitervention: PGD plus APs; Cbmparison: APs plus placebo or AP monotherapy;(Xjtcomes: efficacy and safety; Study design: RCTs. The weighted mean difference(WMD) and risk ratio(RR) along with their 95% CIs were calculated using Review Manager(RevMan) V.5.3 software.Results Five RCTs(n=450) were included and analysed.Two RCTs(n=140) were double-blind and four RCTs(n=409) reported ‘random' assignment with specific description. The PGD group showed a significantly lower serum prolactin level at endpoint than the control group(n=380, WMD:-32.69 ng/mL(95% Cl-41.66 to 23.72),/X0.00001, ^=97%). Similarly, the superiority of PGD over the control groups was also found in the improvement of hyperprolactinaemia-related symptoms. No difference was found in the improvement of psychiatric symptoms assessed by the Positive and Negative Syndrome Scale(n=403,WMD:-0.62(95% Cl-2.38 to 1.15), p=0.49, ^=0%). There were similar rates of all-cause discontinuation(n=330, RR0.93(95% Ci 0.63 to 1.37),/t=0.71, ^=0%) and adverse drug reactions between the two groups. According to the Grading of Recommendations Assessment, Development and Evaluation approach, the level of evidence of primary and secondary outcomes ranged from ‘very low'(14.3%),‘low'(42.8%),‘moderate'(14.3%),to ‘high,(28.6%>.Conclusions Current evidence supports the adjunctive use of PGD to suppress elevated prolactin and improve prolactininduced symptoms without significant adverse events in adult patients with AP-induced hyperprolactinaemia. Highquality RCTs with longer duration are needed to confirm these findings.Trial registration number 42016037017.

Nicotine dependence in community-dwelling Chinese patients with schizophrenia

Background Smoking is a serious public health problem. Patients with schizophrenia usually have a higher prevalence of smoking than the general population, but the level of nicotine dependence is seldom studied, especially for patients living in the communities. Aims This study aimed to examine the level of nicotine dependence in Chinese community-dwelling patients with schizophrenia and explored its associated sociodemographic and clinical factors. Methods A total of 621 patients with schizophrenia treated in the primary care centres of Guangzhou were consecutively recruited. The level of nicotine dependence was assessed with the Chinese version of the Fagerstrom Test for Nicotine Dependence (FTND). Results 148 patients with schizophrenia were current smokers, and the mean (SD) score of FTND was 5.06 (2.55) for all the current smokers. The prevalence of nicotine addiction was 48.0%(95% Cl: 40.0%-56.0%) in patients with current smoking. The patients with schizophrenia had a significantly higher level of nicotine dependence than the Chinese general population. Multiple linear regression analysis revealed that male gender, being unemployed, having a family history of psychiatric disorders, having major medical conditions, first illness episode and less severe positive symptoms were significantly associated with a higher level of nicotine dependence. Conclusion Community-dwelling patients with schizophrenia in China, especially male patients, had a higher level of nicotine dependence than the general population.

青少年抑郁个体化识别与干预的三级框架

Depression in adolescents is a significant public health challenge with a high prevalence and negative outcomes.In the United States,the lifetime and 12-month prevalence rates of major depressive disorder(MDD)among 13-to 18-year-olds were 11.0%and 7.5%,respectively,prior to COVID-19.The COVID-19pandemic has further exacerbated the global trend of increasing rates of adolescent depression.
