Olanzapine-induced Metabolic Syndrome and its Association with -759C>T Polymorphism of the HTR2C Gene in Iraqi Schizophrenic Patients

The hazardous metabolic effects of treating schizophrenia patients with olanzapine comprise serotonin 2C receptor (5-HT2C) antagonists. Metabolic side effects of antipsychotic drugs, including lipid abnormalities, disturbed glucose metabolism, and weight gain, can have a major impact on treating psychiatric patients. The intent of this study was to investigate whether there is an associated link between the genetic polymorphism at -759C>T in the promoter region of the 5-hydroxytryptamine 2C receptor (HTR2C) gene and the metabolic syndrome driven by olanzapine in schizophrenia patients. A cross-sectional study that involved fifty hospitalized patients with schizophrenia. The patients were split into two groups (metabolic and non-metabolic) according to the classification criteria of the metabolic syndrome. The HTR2C promoter region polymorphism was identified through sequencing using the Sanger method after polymerase chain reaction amplification of the extracted deoxyribonucleic acid. Even though none of the genotypes of the -759C>T variant are associated with the propensity to develop metabolic syndrome, there is a significant difference in the -759C>T variant's T allele (p-value = 0.001). The presence of the T allele in the -759 C/T variant was significantly associated with developing metabolic syndrome. Keywords: Schizophrenic patients, Olanzapine, Genetic polymorphism, 5-hydroxytryptamine 2C receptor (HTR2C) gene, -759C>T.

Sexual side effects of antipsychotic drugs in schizophrenia: Protocol for a systematic review with single-arm, pairwise and network meta-analysis of randomized controlled trials and non-randomized studies

Introduction Sexual dysfunctions are common yet underreported side effects of antipsychotics for schizophrenia, affecting 30-80% of treated individuals. These side effects can severely impact social interactions and treatment adherence for individuals with schizophrenia, but comprehensive comparative evidence assessing the risk profiles of different antipsychotics is lacking. This study aims to address this gap using network meta-analysis that integrates data from both randomized-controlled trials (RCTs) and non-randomized studies (NRS). Protocol This systematic review will include both RCTs and NRS focusing on participants with schizophrenia or schizophrenia-like psychoses, without restrictions on symptoms, gender, ethnicity, age, or setting. For interventions, all second-generation antipsychotics will be included. The primary outcome will be the occurrence of at least one sexual adverse event of any kind. Secondary outcomes will be the occurrence of any sexual adverse event evaluated in men and women separately, and any adverse event related to the three phases of sexual response cycle separately: desire (e.g. libido, sexual thoughts), arousal (e.g. erection, lubrication) and orgasm (e.g. ejaculation, anorgasmia), and any adverse effect related to breast dysfunction and menstruation irregularities. Study selection and data extraction will be performed independently by two reviewers. The Cochrane Risk of Bias tool 1 and ROBINS-I will be employed to evaluate the risk of bias for RCTs and NRS, respectively. Single-arm meta-analysis of proportions will synthesize the average frequency of sexual adverse events in treated participants. Pairwise and network meta-analysis of RCTs and NRS will be used to evaluate comparative tolerability. Subgroup and sensitivity analyses will explore possible heterogeneity in results and validate the findings’ robustness. The quality of the evidence will be evaluated using GRADE. Discussion This study will provide vital insights into the sexual side effects of antipsychotics by combining evidence from clinical trials and real-world practice, facilitating better decision-making in choosing the optimal antipsychotic for individuals.

Exploring the Relationships Between Antipsychotic Dosage and Voice Characteristics in Relation to Extrapyramidal Symptoms.

Extrapyramidal symptoms (EPS) are common side effects of antipsychotic drugs. Despite the growing interest in exploring objective biomarkers for EPS prevention and the potential use of voice in detecting clinical disorders, no studies have demonstrated the relationships between vocal changes and EPS. Therefore, we aimed to determine the associations between voice changes and antipsychotic dosage, and further investigated whether speech characteristics could be used as predictors of EPS. Forty-two patients receiving or expected to receive antipsychotic drugs were recruited. Drug-induced parkinsonism of EPS was evaluated using the Simpson-Angus Scale (SAS). Participants' voice data consisted of 16 neutral sentences and 2 second-long /Ah/utterances. Thirteen voice features were extracted from the obtained voice data. Each voice feature was compared between groups categorized based on SAS total score of below and above "0.6." The associations between antipsychotic dosage and voice characteristics were examined, and vocal trait variations according to the presence of EPS were explored. Significant associations were observed between specific vocal characteristics and antipsychotic dosage across both datasets of 1-16 sentences and /Ah/utterances. Notably, Mel-Frequency Cepstral Coefficients (MFCC) exhibited noteworthy variations in response to the presence of EPS. Specifically, among the 13 MFCC coefficients, MFCC1 (t=-4.47, p<0.001), MFCC8 (t=-4.49, p<0.001), and MFCC12 (t=-2.21, p=0.029) showed significant group differences in the overall statistical values. Our results suggest that MFCC may serve as a predictor of detecting drug-induced parkinsonism of EPS. Further research should address potential confounding factors impacting the relationship between MFCC and antipsychotic dosage, possibly improving EPS detection and reducing antipsychotic medication side effects.

The Use of Ascorbic Acid in Adjunctive Treatment for Schizophrenia-Current State of Knowledge.

Schizophrenia is a mental illness characterized by disturbances in the perception of reality, thinking, emotions, and social functioning. This significantly impacts the quality of life of patients and leads to long-term disability. Despite advances in understanding its pathogenesis and treatment, schizophrenia remains a clinical challenge, especially due to the diversity of its symptoms and the complexity of its mechanisms. Schizophrenia is associated with abnormal functioning of the dopaminergic system, disturbances in glutamatergic neurotransmission, and oxidative stress in the brain. In recent years, there has been increasing interest in optimizing the treatment of mental disorders. The potential use of ascorbic acid, or vitamin C, in the therapy of schizophrenia could bring substantial benefits to patients. Ascorbic acid exhibits antioxidant and neuroprotective properties, suggesting its potential efficacy in reducing brain oxidative stress and improving neurotransmission. Additionally, there have been reports of its positive effects on psychotic symptoms and its potential in reducing the side effects of antipsychotic drugs. In this review article, we present the current state of knowledge on the potential use of ascorbic acid in the treatment of schizophrenia as an adjunct to standard pharmacological therapy. We analyze existing clinical studies and the mechanisms of action of vitamin C, suggesting its promising role as an adjunctive therapy in the treatment of schizophrenia. These insights, though not yet widely disseminated, may be significant for the further development of therapeutic strategies for this mental illness.

Sexual Dysfunction with Risperidone in Male and Female Patients of Schizophrenia

Background: Sexual side-effects due to use of Antipsychotic drugs have become one of the most important determinants of treatment compliance. Studies regarding sexual side-effects associated with antipsychotics comprise only a handful in the Indian population, especially so in this north-eastern part of the country. Aims and Objectives 1. To assess the sexual dysfunction associated with Risperidone in male and female patients of Schizophrenia. 2. To compare the sexual dysfunction associated with Risperidone between male and female patients of Schizophrenia. Materials and Methods: This was a hospital based comparative study conducted on 50 clinically stable male and female patients of Schizophrenia on Risperidone only. A Sexual Functioning Questionnaire (SFQ) was administered after assessing the clinical stabilities with the Brief Psychiatric Rating Scale (BPRS). Sexual dysfunction was assessed by calculating the mean scores on all the domains of sexual functioning in SFQ which were then compared across the study groups using the Chi square test . The results were analysed using SPSS Version 16.0 setting the significance threshold at p &lt;0.05. Results: From this study, we inferred that with Risperidone, impairment is seen in desire disorders (12%), arousal disorders (14%), orgasmic difficulties (26%) and overall sexual dysfunction (20%) although not statistically significant. It was also found that in females, Risperidone caused more desire disorders, more arousal disorders and a more overall sexual dysfunction; whereas in case of males, Risperidone caused more arousal disorders, more orgasmic difficulties, more sex related pain problems and a more overall sexual dysfunction; Conclusion: Sexual dysfunction is an important side-effect of Antipsychotic drugs. So clinicians should try to address these side-effects to help patients’ attain a better compliance.

Neuroleptic Malignant Syndrome with haloperidol in a patient with alcohol withdrawal delirium

Neuroleptic malignant syndrome (NMS) is a serious side effect of antipsychotic drugs. Alcohol withdrawal delirium and NMS can present with similar symptoms and hence can create confusion. We present a case of a young male who had no underlying medical illness except alcohol use disorder but developed NMS with a single dose of haloperidol (5 mg) in withdrawal delirium state. Alcohol has been reported to cause polymorphism in the D2 dopamine receptors, which is also the site of action for antipsychotic medicines. Apart from this, dehydration, physical exhaustion, and restraint use may have increased the risk of NMS in our patient. We managed both the conditions, alcohol withdrawal delirium and NMS, simultaneously with lorazepam and bromocriptine.

Dry Eyes Illness in Psychiatric Patients Placed on Antipsychotic Medications

Introduction: Psychosis is used to describe conditions that affect the mind where there has been loss of contact with reality. Most psychotic disorders are treated with a combination of medications and psychotherapy. A significant ocular side effect of anti-psychotic drugs is dry eyes which often do not get adequate attention thus leading to great discomfort to the patient. Methodology: The study was a hospital-based, case-control prospective study where patients diagnosed with a psychotic disorders within the age groups of 18 to 70 years and who have been on anti-psychotic treatment for at least one year were examined by a consultant ophthalmologist. Healthy adults were enrolled from the Ophthalmology outpatient clinic as the control for the study. Result: The case group comprised 53(44.9%) males and 65(55.1%) females. The age group with the highest representation amongst the cases- 29.7% was the 29-38-year-olds. On the medication history, 65(55.1%) started taking antipsychotic drugs within 1-5 years. 65.3% of the respondents were on antipsychotic monotherapy-commonly Olanzapine tablets. Schirmer’s test was normal in most of the participants in both cases 50.8% and control 53.4% but those that have been on medication for 5 years or less demonstrated the highest occurrence of severe dry eyes with a prevalence rate of 23.1% while those on medication for over 10 years showed a higher prevalence of mild dry eyes accounting for 20.8% of the cases. Tear film Break-up Time (TBUT) showed Dry eyes in 50.8% of cases. A significant proportion (56.9%) of those who had been on medication for 1-5 years were found to be exhibiting dry eyes. Conclusion: An association was observed between Dry eye disease and antipsychotic medication as early as within 1-5 years of using the medication. Ophthalmic assessment should be incorporated early in the course of treatment.

Hyperleptinemia contributes to antipsychotic drug-associated obesity and metabolic disorders.

Despite their high degree of effectiveness in the management of psychiatric conditions, exposure to antipsychotic drugs, including olanzapine and risperidone, is frequently associated with substantial weight gain and the development of diabetes. Even before weight gain, a rapid rise in circulating leptin concentrations can be observed in most patients taking antipsychotic drugs. To date, the contribution of this hyperleptinemia to weight gain and metabolic deterioration has not been defined. Here, with an established mouse model that recapitulates antipsychotic drug-induced obesity and insulin resistance, we not only confirm that hyperleptinemia occurs before weight gain but also demonstrate that hyperleptinemia contributes directly to the development of obesity and associated metabolic disorders. By suppressing the rise in leptin through the use of a monoclonal leptin-neutralizing antibody, we effectively prevented weight gain, restored glucose tolerance, and preserved adipose tissue and liver function in antipsychotic drug-treated mice. Mechanistically, suppressing excess leptin resolved local tissue and systemic inflammation typically associated with antipsychotic drug treatment. We conclude that hyperleptinemia is a key contributor to antipsychotic drug-associated weight gain and metabolic deterioration. Leptin suppression may be an effective approach to reducing the undesirable side effects of antipsychotic drugs.

Knowledge of antipsychotic medication and their side effects among psychiatric nurses at a tertiary hospital in Lesotho

Factors that impede the physical health monitoring of patients with severe mental illness are multidimensional, and healthcare providers’ knowledge and expertise regarding antipsychotic medication and side effects remain key determinants of the frequency and quality of screening a patient shall be subjected to. This challenge transcends the monitoring of patients treated with antipsychotics, where scholars have determined a lack of knowledge about screening for adverse effects, resulting in poor clinical assessments among patients prescribed antipsychotics. This study aimed to describe nurses’ knowledge regarding antipsychotic medications and their side effects at the psychiatric hospital in Lesotho. To guide the research process, a quantitative, non-experimental, descriptive approach was employed with 40 nurses out of 44 nurses as respondents, who were selected using convenience sampling, and respondents rated their knowledge regarding the side effects of antipsychotic medication using a Likert scale on a structured research questionnaire. The data were collected using a self-administered questionnaire, analysed using SPSS (version 28), and displayed using tables, frequencies, standard deviations, and means. This study's female respondents comprised 30 (75.0%) and 10 (25.0%) males. The mean age was 39.05 (SD 8.9), with eight years of psychiatry experience. A total of 29 (72.0%) had sufficient antipsychotic knowledge (t = 36.38, df = 39, p &lt; .000), 31 (78.3%) and had adequate knowledge of the side effects of antipsychotic drugs (t = 34.00375, df = 39, p &lt; .000). In conclusion, this study reveals a positive trend in nursing knowledge about antipsychotic medications and associated side effects, highlighting the importance of ongoing professional development to maintain and enhance this expertise.

THE EFFECT OF HYDROXYZINE ON AKATHISIA AND OTHER NEUROLOGICAL SIDE EFFECTS OF ANTIPSYCHOTICS IN THE TREATMENT OF PARANOID SCHIZOPHRENIA

Side effects of antipsychotic drugs are the most urgent problem in the pharmacotherapy of schizophrenia. Medications used to correct side effects of various pharmacological groups, including correctors of cholinolytics, tranquilizers-benzodiazepines, have severe side effects, which justifies the search for no less effective and at the same time safer alternatives. The aim of the study was to evaluate the corrective effect of Hydroxyzine on akathisia and other neurological disorders that develop as side effects of antipsychotic therapy. Materials and methods. The study analyzed the severity of side effects in 43 patients suffering from paranoid schizophrenia receiving monotherapy with antipsychotics, before their administration, on the 7th and 21st day after the start of taking Hydroxyzine. The severity of side effects was assessed by the ESRS scales and the scale of evaluating drug-induced akathisia. Results. A significant corrective effect of Hydroxyzine on akathisia and other neurological side effects of antipsychotics was shown on the 7th day of Hydroxyzine therapy, the severity of Parkinsonism, dyskinesia, akathisia and tremor significantly decreased. Patients noted an improvement in general well-being, a decrease in the level of anxiety associated with the disease, staying in a psychiatric hospital, side effects of psychopharmacotherapy. Hydroxyzine significantly reduced the severity of akathisia, assessed both objectively and subjectively by patients. There was a decrease in the need of patients to move, to change the position of the body, improved sleep, reduced emotional stress. In general, Hydroxyzine had a positive effect in the form of a decrease in pathological motor activity and a decrease in the severity of emotional manifestations associated with the side effect of antipsychotics, which persisted on the 21st day of Hydroxyzine therapy in the absence of clinically significant undesirable side effects. Conclusions. The results of the study show the effectiveness of Hydroxyzine for correcting neurological side effects of antipsychotics along with good tolerability and substantiate the possibility of expanding its use in the complex therapy of paranoid schizophrenia.

Histone deacetylase 1 regulates haloperidol-induced motor side effects in aged mice

BackgroundAntipsychotic drugs prescribed to elderly patients with neuropsychiatric disorders often experience severe extrapyramidal side effects. Previous studies from our group suggest that changes in histone modifications during aging increase the risk for antipsychotic drug side effects, because co-administration of antipsychotics with class 1 histone deacetylase (HDAC) inhibitors could mitigate the severity of motor side effects in aged mice. However, which HDAC subtype contributes to the age-related sensitivity to antipsychotic drug side effects is unknown. MethodsIn this study, we overexpressed histone deacetylase type 1(HDAC1) in the striatum of 3-month-old mice and knocked down HDAC 1 in the striatum of 21-month-old mice by microinjection of AAV9-HDAC1-GFP or AAV9-CRISPR/Cas9-HDAC1-GFP vectors. Four weeks after the viral-vector delivery, the typical antipsychotic drug haloperidol was administered daily for 14 days, followed by motor function assessments through the open field, rotarod, and catalepsy behavioral tests. ResultsYoung mice with overexpressed HDAC1 showed increased cataleptic behavior induced by haloperidol administration, which is associated with the increased HDAC1 level in the striatum. In contrast, aged mice with HDAC1 knocked down rescued locomotor activity, motor coordination, and decreased cataleptic behavior induced by haloperidol administration, which is associated with decreased HDAC1 level in the striatum. ConclusionsOur results suggest that HDAC1 is a critical regulator in haloperidol-induced severe motor side effects in aged mice. Repression of HDAC1 expression in the striatum of aged mice could mitigate typical antipsychotic drug-induced motor side effects.

How sexuality is affected and managed in patients under antipsychotic drugs

IntroductionSexual dysfunction (SD) is a prevalent side effect of antipsychotic drugs (AP), and it impairs patients’ quality of life. Because of the distress caused by it, it should be borne in mind when prescribed since it is responsible for treatment nonadherence or discontinuation. SD affects about 45- 80% of males and 30-80% of females that take it. In SD, all phases of the sexual response cycle may be compromised.ObjectivesThis non-systematic review of the literature aims to better understand the antipsychotic-induced SD and its management to better compliance of AP-treated patients without compromising their quality of life.MethodsA semi-structured review on PubMed linking SD as a side effect of AP drugs.ResultsAll AP drugs can cause SD. It seems related to their mechanism of activity at receptors D2, 5-HT2, α1, H1, and M, which are also involved in sexual function. They do it by diminishing arousal, decreasing libido by blocking motivation and reward system and orgasm indirectly, provoking erectile dysfunction by vasodilatation, and decreasing woman lubrification. Hyperprolactinemia is a significant cause of sexual dysfunctions. Haloperidol, Risperidone, and Amisulpride (prolactin elevating AP) are more likely to cause SD than Olanzapine, Clozapine, Quetiapine, and Aripiprazole (prolactin sparing AP). Although psychotic disorders (Schizophrenia and other psychotic disorders) can impact sexual functioning, according to evidence, there is no denying the role of AP in this issue. Aripiprazole, a D2 partial agonist, has been associated with lower rates of SD and seems to reduce the rates of SD in patients previously treated with other AP. Other AP with the same potential dopamine agonist activity, such as Cariprazine and Brexpiprazole, can probably have the same effect. The management of SD induced by AP drugs should include measuring serum prolactin and modifying risk factors like hypertension, smoking, hyperglycemia, and hypercholesterolemia. In that regard, waiting for spontaneous remission, reducing the dose of the AP prescribed, or switching to Aripiprazole are all viable strategies, if possible. Although the evidence supporting the addition of symptomatic therapies is weak, adding dopaminergic drugs (amantadine, bromocriptine, cabergoline) or drugs with specific effects on sexual functioning (such as phosphodiesterase inhibitors or yohimbine) may be helpful in selected cases.ConclusionsAlthough all AP drugs can cause sexual dysfunction, it is difficult to determine its true prevalence accurately. AP-induced sexual dysfunction can adversely affect compliance and is one of the factors that must be considered when selecting treatment. In summarizing, Aripiprazole has shown to be the AP with the most favorable profile concerning SD. Cariprazine and Brexpiprazole, being also D2 partial agonists, may cause less SD.Disclosure of InterestNone Declared

Antipsychotic-induced priapism: case report and review of the literature.

IntroductionPriapism is a painful and prolonged penile erection in the absence of sexual stimulation. It is a urology emergency that, if not treated, may cause erectile dysfunction. Pharmacologically induced priapism is the most common form of priapism and almost half of all cases are caused by antipsychotic (AP) drugs. Considering priapism is a rare but important side effect, it is of major importance that psychiatrists be aware of it. Thus, we herein report the case of a 46-year-old man that developed priapism upon receiving intramuscular APs in a psychiatric emergency setting.ObjectivesTo alert for the importance of priapism as a potential side effect of AP drugs and to understand the physiological mechanisms involved in antipsychotic-induced priapism.MethodsA non-systematic review of the literature was carried out on PubMed. We looked for reviews and case reports published in the last 10 years containing the terms “priapism”, “antipsychotics” and “psychopharmacology priapism”. We also present a clinical case of antipsychotics-induced priapism.ResultsWe report the case of a 46-year-old man that was brought to the Psychiatric ER by police authorities due to disruptive and aggressive behaviour, a sense of increased energy and power and delusional speech of grandiose and persecutory content. No clinical records of psychosis or bipolar disorder were known, and the patient had never been medicated with AP drugs. The patient was involuntarily admitted to the psychiatric inward for treatment. Due to the aggravation of his aggressive behaviour, with potential danger for himself, other patients and the nursing staff, he was medicated with 5 mg of haloperidol and 25 mg of chlorpromazine. About an hour later the patient developed a painful erection that lasted at least for 4 hours. He was promptly sent to the Urology ER where an intracavernosal aspiration followed by injection of phenylephrine was needed to reverse priapism. APs are the most common cause of drug-induced priapism. Even though typical APs were pointed as more prone to cause this side effect, it is now known that atypical APs, including third-generation ones such as aripiprazole, may also cause priapism. It is thought that the α1- adrenergic antagonist action of most APs inhibits the contraction of smooth muscle in the corpus cavernosum of the penis, impeding venous outflow and thus causing ischemic priapism. To reduce the risk, the dosage of the AP may be reduced or changed to an AP with lower affinity for α1- adrenergic receptors.ConclusionsPriapism is a rare but important side effect of APs. Being aware of it and of its physiological mechanism is of major importance when treating patients with APs.Disclosure of InterestNone Declared

Metabolic side effects in persons with schizophrenia during mid- to long-term treatment with antipsychotics: a network meta-analysis of randomized controlled trials.

Metabolic side effects of antipsychotic drugs can have serious health consequences and may increase mortality. Although persons with schizophrenia often take these drugs for a long time, their mid- to long-term metabolic effects have been studied little so far. This study aimed to evaluate the mid- to long-term metabolic side effects of 31 antipsychotics in persons with schizophrenia by applying a random-effects Bayesian network meta-analysis. We searched the Cochrane Schizophrenia Group's Study-Based Register of Trials (up to April 27, 2020) and PubMed (up to June 14, 2021). We included published and unpublished, open and blinded randomized controlled trials with a study duration >13 weeks which compared any antipsychotic in any form of administration with another antipsychotic or with placebo in participants diagnosed with schizophrenia. The primary outcome was weight gain measured in kilograms. Secondary outcomes included "number of participants with weight gain", fasting glucose, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, and triglycerides. We identified 137 eligible trials (with 35,007 participants) on 31 antipsychotics, with a median follow-up of 45 weeks. Chlorpromazine produced the most weight gain (mean difference to placebo: 5.13 kg, 95% credible interval, CrI: 1.98 to 8.30), followed by clozapine (4.21 kg, 95% CrI: 3.03 to 5.42), olanzapine (3.82 kg, 95% CrI: 3.15 to 4.50), and zotepine (3.87 kg, 95% CrI: 2.14 to 5.58). The findings did not substantially change in sensitivity and network meta-regression analyses, although enriched design, drug company sponsorship, and the use of observed case instead of intention-to-treat data modified the mean difference in weight gain to some extent. Antipsychotics with more weight gain were often also among the drugs with worse outcome in fasting glucose and lipid parameters. The confidence in the evidence ranged from low to moderate. In conclusion, antipsychotic drugs differ in their propensity to induce metabolic side effects in mid- to long-term treatment. Given that schizophrenia is often a chronic disorder, these findings should be given more consideration than short-term data in drug choice.

Exercise to treat psychopathology and other clinical outcomes in schizophrenia: A systematic review and meta-analysis.

Psychopathology and side effects of antipsychotic drugs contribute to worsening physical health and long-term disability, and increasing the risk of mortality in these patients. The efficacy of exercise on these factors is not fully understood, and this lack of knowledge may hamper the routine application of physical activity as part of the clinical care of schizophrenia. To determine the effect of exercise on psychopathology and other clinical markers in patients with schizophrenia. We also looked at several moderators. MEDLINE, Web of Science, Scopus, CINAHL, SPORTDiscus, PsycINFO, and Cochrane Library databases were systematically searched from inception to October 2022. Randomized controlled trials of exercise interventions in patients 18-65years old diagnosed with schizophrenia disorder were included. A multilevel random-effects meta-analysis was conducted to pool the data. Heterogeneity at each level of the meta-analysis was estimated via Cochran's Q, I2, and R2. Pooled effect estimates from 28 included studies (1,460 patients) showed that exercise is effective to improve schizophrenia psychopathology (Hedges' g=0.28, [95% CI 0.14, 0.42]). Exercise presented stronger effects in outpatients than inpatients. We also found exercise is effective to improve muscle strength and self-reported disability. Our meta-analysis demonstrated that exercise could be an important part in the management and treatment of schizophrenia. Considering the current evidence, aerobic and high-intensity interval training exercises may provide superior benefits over other modalities. However, more studies are warranted to determine the optimal type and dose of exercise to improve clinical outcomes in people with schizophrenia.

Schizophrenia, Curcumin and Minimizing Side Effects of Antipsychotic Drugs: Possible Mechanisms.

Schizophrenia is a mental disorder characterized by episodes of psychosis; major symptoms include hallucinations, delusions, and disorganized thinking. More recent theories focus on particular disorders of interneurons, dysfunctions in the immune system, abnormalities in the formation of myelin, and augmented oxidative stress that lead to alterations in brain structure. Decreased dopaminergic activity and increased phospholipid metabolism in the prefrontal cortex might be involved in schizophrenia. Antipsychotic drugs used to treat schizophrenia have many side effects. Alternative therapy such as curcumin (CUR) can reduce the severity of symptoms without significant side effects. CUR has important therapeutic properties such as antioxidant, anti-mutagenic, anti-inflammatory, and antimicrobial functions and protection of the nervous system. Also, the ability of CUR to pass the blood-brain barrier raises new hopes for neuroprotection. CUR can improve and prevent further probable neurological and behavioral disorders in patients with schizophrenia. It decreases the side effects of neuroleptics and retains lipid homeostasis. CUR increases the level of brain-derived neurotrophic factor and improves hyperkinetic movement disorders. CUR may act as an added counteraction mechanism to retain cell integrity and defense against free radical injury. Thus it appears to have therapeutic potential for improvement of schizophrenia. In this study, we review several properties of CUR and its ability to improve schizophrenia and minimize the side effects of antipsychotic drugs, and we explore the underlying mechanisms by which CUR affects schizophrenia and its symptoms.

The response of subgroups of patients with schizophrenia to different antipsychotic drugs: a systematic review and meta-analysis

As comparatively few trials in subgroups of patients with schizophrenia have been done, clinicians need to know whether they can rely on the results of randomised controlled trials (RCTs) in the general population of patients with schizophrenia. We aimed to compare the efficacy and side-effects of antipsychotic drugs in different subgroups. In this systematic review and meta-analysis, we searched reference lists of previous systematic reviews and meta-analyses, the Cochrane Schizophrenia Group's Study-Based Register (from database inception to April 27, 2020), and PubMed (from April 1, 2020 to June 14, 2021). We excluded studies in patients with stable schizophrenia (ie, relapse prevention studies), studies with a high risk of bias, and studies from mainland China due to quality concerns concerning allocation and masking methods. We included single-blind RCTs or better that assessed one or more of 16 second-generation and 18 first-generation antipsychotics in the general population of patients with schizophrenia or in one or more of the subgroups: children and adolescents (age range as defined in the original studies), patients with a first episode, patients with predominant or prominent negative symptoms, patients with comorbid substance use, patients with treatment-resistant schizophrenia, or older patients (age range as defined in the original studies). Two authors independently screened the results of the search, retrieved full-text articles, and checked the inclusion criteria. Using the Preferred Reporting Items for Systematic Reviews and Meta-analyses guideline, all parameters were extracted in duplicate. The primary outcome was change in overall symptoms. We compared drug efficacy between subgroups, by sex, schizoaffective disorder versus schizophrenia, and study origin using random-effects, inverse variance meta-analyses and random-effects subgroup tests, and meta-regression. We included 537 RCTs with 76 382 participants, 26 627 (34·9%) women, 49 755 (65·1%) men, mean age 37·3 years (range of means 7·9-80·2; ethnicity data not available). 412 RCTs included patients in the general population of patients with schizophrenia, 42 included patients with treatment-resistant schizophrenia, 25 included children and adolescents, 20 included patients with their first episode, 20 included patients with predominant or prominent negative symptoms, 13 included patients with comorbid substance use, and 11 included older patients. Of 507 random-effects subgroup tests done, 46 (9%) showed a significant difference (p<0·05) between subgroups, but there was no clear indication as to which drug should be used in which subgroup. The effects of antipsychotics in various patient subgroups were usually similar to those in the general population of patients with schizophrenia, but comparably few studies contributed to the subgroups, in particular in terms of side-effects. If the evidence for treatment in a given subgroup is small, guideline makers and clinicians should consider using the results in the much better studied group of the general population of patients with schizophrenia.

Health promotion in psychiatry and mental health: The example of metabolic syndrome and nursing practices

Introduction: Life expectancy in psychiatric patients is reduced by 15 to 20 years due to the presence of comorbidities and the lifestyle of these patients. Metabolic syndrome, also a side effect of antipsychotic drugs, is an aggravating factor of this phenomenon, which is why health promotion is essential. The objective of this study is to describe the knowledge, attitudes, and practices of psychiatric nurses with regard to metabolic syndrome, using N. Pender's health promotion model as a framework.Methodology: A multicenter descriptive study using a «knowledge, attitude, practice» survey was conducted in 16 psychiatric departments in the Ile-de-France region. 70 nurses were interviewed via online questionnaires.Results: The results show partial knowledge. A gap exists between attitudes and nursing practices. The nurses' actions mainly involve counseling. The type of nursing knowledge is discussed, as well as the need for reflection on the nurse-patient relationship. Nursing interventions need to be further developed to better manage metabolic syndrome.Conclusion: Training is needed to carry out preventive measures and promote health more effectively.

A Survey Study on the Status of Somatic Symptoms in Young and Middle-Aged Patients with Mental Illness during Long-Term Hospitalization.

Psychiatric disorders include severe psychiatric disorders and those in general with some psychiatric disorders having a clear etiology or in which a significant psychiatric predisposing factor is present. Whereas, psychiatric disorders precisely refer to those characterized by mild depression and mild anxiety and appear to affect a large number of people in any community. It has been reported that the disease is highly prevalent and has a huge impact on the individual, family, and community levels, resulting in a heavy burden on the healthcare system of a country. To explore the status of somatic symptoms in young and middle-aged psychiatric patients during long-term hospitalization, a total of 114 young and middle-aged psychiatric patients with prolonged hospitalization (more than 5 years) were included. Data information of the hospitalized patients was recorded, including preadmission somatic symptoms, electrocardiogram (ECG), echocardiogram, abdominal ultrasound, and blood tests. In addition, a homemade questionnaire was administered, and general information about the patients was also collected, including gender, age, current medication use, and duration of medication use. Correlations between cardiometabolic disease, osteoporosis, and long-term oral antipsychotic medication were analyzed in these young and middle-aged patients. The prevalence of comorbid somatic symptoms was 77.2%, and concomitant disorders included mainly cardiometabolic disorders, osteoporosis, pulmonary infections, cerebrovascular disorders, digestive disorders, fractures, and skin conditions. The incidence of somatic symptoms caused by long-term use of antipsychotic drugs was about 88.6%, and the incidence of concomitant somatic symptoms was higher in young and middle-aged psychiatric patients who were hospitalized for a long time. The current study observed a high prevalence of somatic symptoms in young and middle-aged patients with long-term inpatient psychiatric illness. Endocrine and metabolic disorders, particularly dyslipidemia, may trigger a range of deleterious effects. In addition to this, there is a high incidence of osteoporosis. Special attention should be paid to the side effects of antipsychotic drugs, and appropriate measures are needed to make early diagnosis and provide early treatment to reduce the occurrence of cardiometabolic diseases and osteoporosis.

Amantadine in the Treatment of Sexual Inactivity in Schizophrenia Patients Taking Atypical Antipsychotics-The Pilot Case Series Study.

Sexual dysfunctions in people with schizophrenia are more severe than in the general population and are an important element in the treatment of schizophrenia. The mechanism of sexual dysfunction in patients treated for schizophrenia may be related to the side effects of antipsychotic drugs (hyperprolactinemia, suppression of the reward system), but it may also be related to the pathogenesis of schizophrenia itself. The aim of the study was to present the possibility of using amantadine in the treatment of sexual dysfunction in schizophrenia without the concomitant hyperprolactinemia. In an open and naturalistic case series study, five men treated for schizophrenia in a stable mental state were described. All patients reported a prolonged lack of sexual desire and sexual activity prior to treatment with amantadine. After exclusion of hyperprolactinemia, patients received amantadine 100 mg in the evening. Sexual dysfunction was assessed using subscales of the 14-point Short Form of the Changes in Sexual Functioning Questionnaire (CSFQ-14). On subsequent visits after 1, 2 and 3 months of administration of amantadine, an improvement in sexual functioning was observed in all patients. Although this is only the preliminary report, amantadine may become a new indication for the treatment of sexual dysfunction in schizophrenia patients.
