Recent advances in machine learning (ML) promise far-reaching improvements across medical care, not least within psychiatry. While to date no psychiatric application of ML constitutes standard clinical practice, it seems crucial to get ahead of these developments and address their ethical challenges early on. Following a short general introduction concerning ML in psychiatry, we do so by focusing on schizophrenia as a paradigmatic case. Based on recent research employing ML to further the diagnosis, treatment, and prediction of schizophrenia, we discuss three hypothetical case studies of ML applications with view to their ethical dimensions. Throughout this discussion, we follow the principlist framework by Tom Beauchamp and James Childress to analyse potential problems in detail. In particular, we structure our analysis around their principles of beneficence, non-maleficence, respect for autonomy, and justice. We conclude with a call for cautious optimism concerning the implementation of ML in psychiatry if close attention is paid to the particular intricacies of psychiatric disorders and its success evaluated based on tangible clinical benefit for patients.

SUMMARY: Delusional infestation (delusional parasitosis) is a relatively rare condition but it has been of interest to a wide range of professionals, including entomologists, zoologists and dermatologists, as patients predominantly seek help from specialties other than psychiatrists. The illness requires a multidisciplinary approach and a strong bond of trust between the treating clinician and the patient to ensure the best possible outcome. This article discusses how clinicians in all specialties should approach patients presenting with the disorder and outlines differential diagnosis and associated laboratory tests. It considers the evidence base for treatment and the success of psychodermatology clinics that provide a 'neutral setting' for consultation to address the problem of patients' non-engagement. Such clinics are few, and there is a need to develop disease-specific pathways in primary care and hospital settings to improve prognosis. [ABSTRACT FROM AUTHOR]

SUMMARY: Psychodermatology is an emerging field at the interface between psychiatry, psychology and dermatology. There is a strong bidirectional relationship between a number of dermatological disorders and psychiatric disorders. This article provides an overview of psychiatric disorders with dermatological symptoms, and dermatological disorders with secondary psychophysiological consequences. The principles of management and our insights into establishing a psychodermatology service in the UK are discussed. [ABSTRACT FROM AUTHOR]

Background. Dysthymia is a common mental disorder, associated with considerable disability and high co-morbidity. This review assessed the role of pharmacological treatment. Methods. All randomized-controlled trials that compared active drug versus placebo for dysthymic patients were included. Pooled relative risks (RR) and 95% confidence intervals (CI) were calculated with the Random Effect Model method. Where possible, number needed to treat and number needed to harm were estimated. Results. Fifteen trials were included for the main comparisons. Similar results were obtained in terms of efficacy for different groups of drugs, such as tricyclic (TCA), selective serotonin reuptake inhibitors (SSRI), monoamine oxidase inhibitors (MAOI) and other drugs (sulpiride, amineptine, and ritanserin). The pooled RR treatment response was 0·68 (95% CI 0·59–0·78) for TCA, 0·64 (95% CI 0·55–0·74) for SSRIs, 0·59 (95% CI 0·48–0·71) for MAOIs. Other drugs (amisulpride, amineptine and ritanserin) showed similar results. Patients treated on TCA were more likely to report adverse events, compared with placebo. There were no differences in response to active treatment when dysthymia was compared to either dysthymia plus major depression or briefer non-major depressive states. Conclusions. Drug treatment appears to be effective in the short-term management of dysthymic disorder. The choice of drug should take into account specific side-effects profile of each drug.

Neuropsychiatric sequalae to coronavirus disease 2019 (COVID-19) infection are beginning to emerge, like previous Spanish influenza and severe acute respiratory syndrome episodes. Streptococcal infection in paediatric patients causing obsessive compulsive disorder (PANDAS) is another recent example of an infection-based psychiatric disorder. Inflammation associated with neuropsychiatric disorders has been previously reported but there is no standard clinical management approach established. Part of the reason is that it is unclear what factors determine the specific neuronal vulnerability and the efficacy of anti-inflammatory treatment in neuroinflammation. The emerging COVID-19 data suggested that in the acute stage, widespread neuronal damage appears to be the result of abnormal and overactive immune responses and cytokine storm is associated with poor prognosis. It is still too early to know if there are long-term-specific neuronal or brain regional damages associated with COVID-19, resulting in distinct neuropsychiatric disorders. In several major psychiatric disorders where neuroinflammation is present, patients with abnormal inflammatory markers may also experience less than favourable response or treatment resistance when standard treatment is used alone. Evidence regarding the benefits of co-administered anti-inflammatory agents such as COX-2 inhibitor is encouraging in selected patients though may not benefit others. Disease-modifying therapies are increasingly being applied to neuropsychiatric diseases characterised by abnormal or hyperreactive immune responses. Adjunct anti-inflammatory treatment may benefit selected patients and is definitely an important component of clinical management in the presence of neuroinflammation. [ABSTRACT FROM AUTHOR]

Background: Clozapine, an antipsychotic with unique efficacy in treatment-resistant psychosis, is associated with increased susceptibility to infection, including pneumonia.Aims: To investigate associations between clozapine treatment and increased risk of COVID-19 infection in patients with schizophrenia-spectrum disorders who are receiving antipsychotic medications in a geographically defined population in London, UK.Method: Using information from South London and Maudsley NHS Foundation Trust (SLAM) clinical records, via the Clinical Record Interactive Search system, we identified 6309 individuals who had an ICD-10 diagnosis of schizophrenia-spectrum disorders and were taking antipsychotics at the time of the COVID-19 pandemic onset in the UK. People who were on clozapine treatment were compared with those on any other antipsychotic treatment for risk of contracting COVID-19 between 1 March and 18 May 2020. We tested associations between clozapine treatment and COVID-19 infection, adjusting for gender, age, ethnicity, body mass index (BMI), smoking status and SLAM service use.Results: Of 6309 participants, 102 tested positive for COVID-19. Individuals who were on clozapine had increased risk of COVID-19 infection compared with those who were on other antipsychotic medication (unadjusted hazard ratio HR = 2.62, 95% CI 1.73-3.96), which was attenuated after adjusting for potential confounders, including clinical contact (adjusted HR = 1.76, 95% CI 1.14-2.72).Conclusions: These findings provide support for the hypothesis that clozapine treatment is associated with an increased risk of COVID-19 infection. Further research will be needed in other samples to confirm this association. Potential clinical implications are discussed. [ABSTRACT FROM AUTHOR]

Introduction: Schizophreniform Disorder is described pretty similar to schizophrenia, but with the difference of the symptoms duration which have to last for at least 1 month but less than 6 months. Patients have to be back at their baseline functional level once the disorder has resolved. This is a heterogeneous group of patients who have either a disorder similar to schizophrenia or something closer to a mood disorder. Objectives: To analyze clinical, psychopathological and epidemiological characteristics of schizophreniform disorder and also review causes, incidence, prevalence, diagnostic, therapeutic tools and the importance of maintaining the treatment, because of the abandonment of the treatment, which is a predictor of relapses. Methods: A review of the main impact literature concerning schizophreniform disorder is done during the last five years: prevalence, incidence, pathogenesis and its relationship with other psychiatric disorders encoded in DSM-V are studied. Results: The etiology is unknown. Psychotic symptoms can be treated with antipsychotics for 3 to 6 months. They usually respond faster than patients with schizophrenia (75% vs 20% respond within 8 days). Conclusions: The disease has a favorable prognosis, and has similarities with mood disorders. However, some data suggest a close relationship to schizophrenia. In support of the relationship with mood disorders, patients have more affective symptoms and a better outcome than patients with schizophrenia.

Introduction: There is an increasing rate of treatment resistance in severe psychiatric disorders (SPDs), which indicates the necessity for finding new therapeutic interventions, because of the significant negative impact these disorders have on the patient's quality of life, functionality, and other important parameters. In clinical practice, SPDs are estimated to represent up to 30-60% of all diagnosed cases. Schizophrenia spectrum disorders (SSD), major depressive disorder (MDD), and bipolar disorders (BDs) are associated with lower response to a large variety of therapeutic approaches. In this context, new technologies should be considered for SPDs, and non-invasive neuromodulation techniques can be explored as add-ons to ongoing therapeutic interventions. Objectives: A literature review was conducted to detect the available evidence to support recommendations for neuromodulation techniques in SPDs. Methods: Three electronic databases (PubMed, Cochrane, Google Scholar) were searched for papers corresponding to the keywords "treatment-resistant psychiatric disorders" and "neuromodulation" or "electroconvulsive therapy" (ECT) or "transcranial magnetic stimulation" (TMS) or "transcranial direct current stimulation" (tDCS), published from the beginning of the respective databases up to July 2023. Results: After the initial search, 1258 papers surfaced, but only 72 remained to be included in the analysis, after filtering them according to the inclusion and exclusion criteria. TMS may improve both depressive and manic symptoms, but also reports of polarity changes were found, indicating the need for careful monitoring of treatment-emergent affective switches (TEAS). TMS may also improve cognitive functions, although not sufficient evidence was found to support this observation clearly. The efficacy of temporoparietal TMS in schizophrenia has not been proven with certainty, although this intervention may improve positive symptoms. ECT was an effective and well-tolerated intervention for severe mood episodes, SSD, and BDs. Depressive symptoms responded to tDCS in bipolar/monopolar patients, but reports of TEAS in the BDs population have been reported. Conclusions: Non-invasive neuromodulation techniques may represent an efficient option in patients with SPD, but more good-quality trials are needed before this recommendation is formulated in clinical guidelines.

Introduction: Background : Somatic symptoms disorders are usually comorbid with depressive disorders despite that there is little evidence for effective treatment for it. Repetitive transcranial magnetic stimulation (rTMS) have been approved by FDA for mildly resistance depression. From this point we hypothesized that rTMS delivered over the prefrontal cortex (PFC) may be useful in somatic symptoms disorder. Therefore, in our case report we want to shed light on the potential effectiveness of rTMS in somatic symptoms disorder. Objectives: case report Methods: case report Results: Case Report : A 65-year-old Omani female with multiple medical comorbidities on multiple medications. She presented complaining of multiple somatic complains in the last 2 years after visiting multiple clinics and underwent several specialists' examinations, investigations and procedure for somatic treatments, all of them where normal. Then patient was seen by different psychiatric clinic multiple anti-depressant and adjuvant anti-psychotic medication were try, patient still not improve. Patient get admitted to hospital for observation and management. Initially she was preoccupying by her somatic complain kept on Fluoxetine and Olanzapine along with that topiramate was added, but still with minimal improvement. Then rTMS was added to her management plan following Intermittent theta burst (iTBS) rTMS protocol. After complete all sessions of rTMS patient was recovering from her all symptoms, no complain report from her. Conclusions: Conclusion : our case highlights the important of investigated more thoroughly in rTMS as treatment option for Persistent Somatic symptoms Disorder.

Introduction: Paliperidone Palmitate (PP) is an atypical antipsychotic, approved by the FDA for acute and maintenance treatment of schizophrenia and schizoaffective disorder. It has a relatively safety profile, and reported cases of paliperidone palmitate-induced angioedema or anaphylaxis are uncommon. Objectives: We intend to present a case of paliperidone palmitate-induced anaphylaxis to alert clinicians regarding this rare, but possible complication. Methods: Non-systematic review of the literature and report of a case study. Results: Long-acting injectable Paliperidone Palmitate (LAIPP) is a safe and effective alternative to oral Paliperidone, with less incidence of disease relapse related to medication non-compliance. Substance use disorder (SUD) is highly prevalent in first-episode psychosis (FEP), and it is associated to decreased treatment compliance, which impairs the outcomes of these patients. Therefore, several authors have been recommended long-acting injectable antipsychotics (LAI-AP), such the LAIPP, as a first line for treatment of FEP-SUD patients. The most common side effects associated with LAIPP are injection site reactions, extrapyramidal symptoms, hyperprolactinemia, sedation, hypersalivation, orthostatic hypotension, tachycardia, and weight gain. Hypersensitivity reactions have rarely been reported and may be dose-dependent. We report a case of a 20-year-old female, without medical history and no history of allergies, who was medicated with once-monthly LAIPP at dose 100 mg for the maintenance treatment of a first psychotic episode associated with cannabis abuse. Approximately 24 hours after the first monthly injection dose, she was admitted in the emergency room (ER) presenting an increasing angioedema associated with stridor, requiring endotracheal intubation and administration of adrenaline, clemastine and hydrocortisone during the assessment in the ER. After clinical stabilization, she was transferred to the internal medicine ward, and following a full recovery, she was discharged 6 days later while being medicated with Olanzapine 15 mg/day, Lorazepam 3 mg/day and Sertraline 50 mg/day. LAIPP was suspected as the etiology of the anaphylaxis reaction due to temporal relationship of its onset with therapy administration and by the exclusion of other potential causes. Consequently, LAIPP was discontinued at discharge. Conclusions: This report shows the possibility of a late and potentially life-threatening anaphylactic reaction to LAIPP. So, all physicians should be aware of this potential complication, which requires timely recognition and management. Disclosure of Interest: None Declared [ABSTRACT FROM AUTHOR]

Introduction: Delaware's recent longevity and aging trends predict a continual increase in the number of cancer survivors. As the cancer survivors live longer and age, the prevalence of comorbid chronic conditions tends to increase. Dual burden of cancer and comorbid chronic conditions can have significant and wide-ranging ramifications for cancer survivors. Comorbidity potentially affects the development, stage at diagnosis, treatment options, recurrence and long-term survival of people with cancer. Detailed delineation of Delaware adult cancer survivors including an exploration of comorbidity is critical. Objectives: The primary objective was to characterize selected chronic conditions among Delaware adults with cancer in order to present: (i) disparities amongst cancer survivors by select sociodemographic and survivorship characteristics, and (ii) compare the prevalence of chronic conditions among cancer survivors and adult Delawareans without a cancer diagnosis. Methods: Combined data (2018, 2020 and 2021) for Delaware were obtained from the Behavioral Risk Factor Surveillance System. The final data set included 927 Delawareans with at least one type of cancer (excluding skin cancers other than melanoma) and 11,917 participants without a cancer diagnosis. Descriptive statistics examined sociodemographic characteristics and chronic conditions in Delawareans with and without a cancer diagnosis. Results: Amongst adult Delawareans, 5.1% (CI: 4.6–5.5) were cancer survivors. Across the state, the majority of cancer survivors (76.8%) reported having only one cancer diagnosis. In this sample of Delaware cancer survivors, 83.5% identified as White. Majority were female (57.4%), aged 65 or older (58.9%), had some college or more education (63.7%), and with an income of $50,000 or more (51.1%). Arthritis (46.3%), diabetes (21.5%), depression (18.7%), asthma (14.1%), chronic obstructive pulmonary disease (13.7%) angina (11.9%) and heart attack (11.6%) were the most prevalent comorbid conditions. Prevalence of certain chronic conditions was 2-3 times higher among cancer survivors. Nearly 23% reported not receiving instructions regarding cancer follow-up care. Conclusions: Cancer survivors have unique concerns. Results aim to facilitate targeted interventions aimed at coordinated managed care among cancer survivors in Delaware. This study bolsters the ongoing public health effort towards the Healthy People 2030 goal of increasing the proportion of cancer survivors.

Introduction: Weight gain, QT interval prolongation, and dyslipidemias associated with the chronic use of some antipsychotic medications can explain a higher prevalence of cardiovascular risk in these psychiatric population. The D'Agostino Index include some factors such as age, total cholesterol, high-density lipoproteins, systolic blood pressure increased, antihypertensive treatment, smoking, and diabetes, to estimate an individual's risk (low, moderate or severe) of developing a cardiovascular event through a period of 10 years or throughout the patient's lifetime. Objectives: To compare the degree of cardiovascular risk using the D'Agostino Index, among different antipsychotic medications. Methods: An estimation of cardiovascular risk (low, moderate, or high) was performed with the D´Agostino index in a sample of 144 patients (82 men and 62 women) mean age 45,2 +/- 10.13. All patients were treated for at least one year at a therapeutic dose and adhered to their treatment regimen correctly. Subjects with some relevant pre-existing unstable heart disease were excluded. All patients previously provided informed consent and were of legal age. Clinical data on medical history, concomitant medications, and risk factors were collected. A completed physical exam, waist circumference, lab sample, a lifestyle scale, and an evaluation of vital signs in accordance with European Society of Hypertension were evaluated. Statistical analysis was carried out using the statistical software SPSS version 26.0. A significance level α=0.05 was considered throughout the study. Results: The four most consumed antipsychotics were risperidone 9.72% (n=14), paliperidone 25.7% (n=37), olanzapine 14.6% (n=21), and aripiprazole 34.7% (n=50). Descriptively, it was observed that the drugs most associated with moderate or high risks were paliperidone (37.8%) and olanzapine (33.3%), risperidone (28.6 %). Aripiprazol (22%) was the less associated compound with moderate/high cardiovascular risk. Conclusions: Subjects treated with olanzapine and paliperidone showed a higher association with cardiovascular risk. Predicting cardiovascular risk could provide individual benefits by enabling lifestyle modifications, pharmacological treatment changes, or closer monitoring to reduce cardiovascular risk.

After numerous unsuccessful attempts to create a therapy that could alter the course of Alzheimer's disease, first monoclonal antibodies targeting amyloid-β in the brain have finally shown consistent evidence of clinical effectiveness. These therapies not only slow the progression of the disease, but also show positive results in secondary clinical outcomes and reduced amyloid-β levels on PET scans. This presentation will examine the main features of the previous failed trials and explore possible reasons for their lack of success in developing a treatment for early-stage Alzheimer's disease. It will also compare the safety profiles of various antibodies and point out precautions that should be taken when using them in regular clinical practice. Furthermore, it will be discussed how blood-based biomarkers can revolutionize the clinical care pathway, making it easier to adopt antibody treatments. A comprehensive model that integrates case-finding and treatment across various healthcare sectors will be proposed. In conclusion, we may have made a significant breakthrough by demonstrating that reducing amyloid-β levels leads to clinical benefits, not just changes in biomarkers. As the new generation of drugs becomes more commonly used, we will see whether their statistical effectiveness translates into meaningful clinical changes. This could mark the start of a new phase in the development of drugs for Alzheimer's disease. Disclosure of Interest: None Declared [ABSTRACT FROM AUTHOR]

The recent network perspective of depression conceptualizes depression as a dynamic network of causally related symptoms, this in contrast with the traditional view of depression as a discrete latent entity that causes all symptoms. Electroconvulsive therapy (ECT) is an effective treatment for severe depression, but little is known about the temporal trajectories of symptom improvement during a course of ECT. We will present the results of a study that investigates the temporal trajectories of individual symptoms during treatment with ECT. Disclosure of Interest: None Declared [ABSTRACT FROM AUTHOR]

Introduction Tardive dyskinesia (TD) is a serious medical condition that affects a significant proportion of patients treated with antipsychotic agents. Objective To report a patient who developed tardive dyskinesia after initiation of antipsychotic and antidepressant treatment. Case report Miss H. is 24-year-old Tunisian woman who had been diagnosed with bipolar disorder 6 years ago. She received various drugs: olanzapine, haloperidol, amisulpride, sertraline, paroxetine, etc. On November 2013, she first complained of hand tremor and then developed severe dystonia of the trunk and chorea. A series of laboratory tests was performed after the onset of these involuntary movements. It included complete blood count, liver, renal, and thyroid function tests, blood prolactin level, blood glucose level, blood copper level and ceruloplasmin level. A brain MRI was also performed. These examinations showed no specific findings. The diagnosis of TD was presumed. The patient was first treated with amisulpride, lorazepam, avlocardyl and piracetam until May 2014. Then, amisulpride was substituted by olanzapine until August 2015. The luck of improvement led to her admission. We stopped antipsychotic treatments and prescribed her vitamin E (900 mg/day), clonazepam (6 mg/day) and vitamin B6. The follow-up led to the decline of the Abnormal Involuntary Movement Scale (AIMS) score of 7 points over 6 weeks. Conclusion TD remains a serious side effect that worsens the prognosis and affects the quality of life of patients. Cluster randomised trial should be done in order to develop practice recommendations for prevention and management of TD. [ABSTRACT FROM AUTHOR]

Introduction Cerebral abscesses are rare, occurring in approximately 0.3–1 per 100 000 patients. Mortality rate still remains as high as 22%. Very few cases of acute psychotic episodes associated with brain abscess have been reported. Objectives To present a case report of a patient with schizofrenia associated with multiple brain abscesses, focusing on clinical features and managing challenges. Methods Presentation of a clinical case supported by a non-systematic review of literature containing the key-words “brain abscess”, “psychosis” and “schizophrenia” Results This is a case report of a male 44-year-old patient with a known history of schizophrenia since the age of 18 and with multiple brain abscesses diagnosed 2 month ago. He was admitted to our inpatient service after discontinuation of her medication resulting in an acute psychotic episode. Antibiotic therapy with rifampicine, metronidazole, trimethoprim and sulfamethoxazole was started. Also, administration of clozapine was initiated (up to 400mg/day) with partial improvement, so aripiprazole was added (up to 45 mg/day), with insufficient response. We suspected of a drug interaction between rifampicine (known potent broad inducer of drug-metabolizing enzymes) and antipsychotic medication, so we decided to change aripiprazole to amisulpride 1200 mg/day, which CYP-catalyzed metabolism appears to be minor. A significant improvement in positive symptoms and mood was observed. The patient has since had no delusions or hallucinations and is living independently at home. Conclusions This clinical case highlights the possible association between brain abscesses and relapses in schizophrenia. It is of utmost importance to be aware for possible drug interactions between antibiotic therapy and antipsychotic medication. Disclosure No significant relationships.

Introduction Although monotherapy is preferable, in every day clinical practice polypharmacy is often unavoidable due to the need of treatment enhancement or cross-titration phases with shorter or longer overlaps of two or more drugs. However, administration of more than one drug treatment is often associated with more side effects. Objectives The aim of the present post-hoc analysis was to examine treatment emergent adverse events (TEAEs) during co-administration of cariprazine with other antipsychotics. Methods Treatment emergent adverse event data (TEAE) from a randomized, double-blind, parallel-group, active-controlled study (EudraCT Number: 2012-005485-36) in adult patients with schizophrenia having predominant negative symptoms was examined in the first two weeks of the double-blind treatment period, where gradual cross-titration occurred between cariprazine (3-6 mg/day) and other antipsychotics (including amisulpride, aripiprazole, fluphenazine, haloperidol, olanzapine, paliperidone, quetiapine, and sertindole). Thereafter, 24 weeks of cariprazine monotherapy followed. Results During the cross-titration period, 17.83% of patients experienced at least one TEAE. The TEAEs were in line with the well-established safety data: nausea (2.61%), insomnia (2.17%), headache (2.17%), akathisia (1.74%) and restlessness (1.3%) were the most common. Most events were mild in severity (66.1% mild, 32.2% moderate, 1.7% severe (insomnia)). Conclusions While not definitive, and limited by small sample size, the co-administration of cariprazine with other antipsychotics did not show an unexpected safety profile or overlapping toxicities. This is an important finding, if intermittent or longer co-administration of other antipsychotics are unavoidable with cariprazine treatment.

Introduction Treatment-resistant schizophrenia (TRS) affects 30% of people with a diagnosis of schizophrenia, and is defined as nonresponse to at least two trials of antipsychotic medication of adequate dose and duration. Clozapine is the only evidence-based treatment for TRS. Cariprazine may be considered significantly more efficacious than risperidone in improving negative symptoms of schizophrenia. Objectives To describe the experience of using cariprazine in combination with clozapine in patients with refractory schizophrenia and negative symptoms. Methods Qualitative design. We present a case report study of a 47-year-old male with a diagnosis of TRS, treated in our outpatient mental health clinic for twenty years. The patient experiences crystallized delusional ideas of harm, self-referential, paranoid and mystical-messianic content, phenomena of theft and thought reading, egodistonic auditory hallucinations. No substance use disorder was observed. He made several suicide attempts in the context of intense suffering and psychotic anguish. Clozapine 400mg/day was instituted after no response to treatment with amisulpride, paliperidone, olanzapine or aripiprazole. The intensity of positive symptoms was reduced (experiences of damage, commenting and insulting auditory hallucinations, self-referentiality), as well as the emotional and behavioral repercussions. Persistent negative symptoms appeared such as apathy, abulia, clinophilia, anergy, social isolation, affective flattening, impairing his functionality. Results Neuroimaging and periodic blood tests results were normal. Oral cariprazine was added in ascending doses up to 4.5mg with good tolerance. The patient showed remission of apathy, enhancement of behavioral activation, socialization and motivation to perform occupational activities. Conclusions Combinations of clozapine with partial agonists may improve the quality of life in refractory schizophrenia. Disclosure No significant relationships.

Background: In the treatment of psychosis, agitation and aggression in Alzheimer's disease, guidelines emphasise the need to 'use the lowest possible dose' of antipsychotic drugs, but provide no information on optimal dosing.Aims: This analysis investigated the pharmacokinetic profiles of risperidone and 9-hydroxy (OH)-risperidone, and how these related to treatment-emergent extrapyramidal side-effects (EPS), using data from The Clinical Antipsychotic Trials of Intervention Effectiveness in Alzheimer's Disease study (Clinicaltrials.gov identifier: NCT00015548).Method: A statistical model, which described the concentration-time course of risperidone and 9-OH-risperidone, was used to predict peak, trough and average concentrations of risperidone, 9-OH-risperidone and 'active moiety' (combined concentrations) (n = 108 participants). Logistic regression was used to investigate the associations of pharmacokinetic biomarkers with EPS. Model-based predictions were used to simulate the dose adjustments needed to avoid EPS.Results: The model showed an age-related reduction in risperidone clearance (P < 0.0001), reduced renal elimination of 9-OH-risperidone (elimination half-life 27 h), and slower active moiety clearance in 22% of patients, (concentration-to-dose ratio: 20.2 (s.d. = 7.2) v. 7.6 (s.d. = 4.9) ng/mL per mg/day, Mann-Whitney U-test, P < 0.0001). Higher trough 9-OH-risperidone and active moiety concentrations (P < 0.0001) and lower Mini-Mental State Examination (MMSE) scores (P < 0.0001), were associated with EPS. Model-based predictions suggest the optimum dose ranged from 0.25 mg/day (85 years, MMSE of 5), to 1 mg/day (75 years, MMSE of 15), with alternate day dosing required for those with slower drug clearance.Conclusions: Our findings argue for age- and MMSE-related dose adjustments and suggest that a single measure of the concentration-to-dose ratio could be used to identify those with slower drug clearance.

Clozapine is the only licensed pharmacotherapy for treatment-resistant schizophrenia. However, response to clozapine is variable. Understanding the demographic and clinical features associated with response to clozapine may be useful for patient stratification for clinical trials or for identifying patients for earlier initiation of clozapine. We systematically reviewed the literature to investigate clinical and demographic factors associated with variation in clozapine response in treatment-resistant patients with schizophrenia spectrum disorders. Subsequently, we performed a random-effects meta-analysis to evaluate differences in duration of illness, age at clozapine initiation, age of illness onset, body weight and years of education between clozapine responders and non-responders. Thirty-one articles were eligible for qualitative review and 17 of these were quantitatively reviewed. Shorter duration of illness, later illness onset, younger age at clozapine initiation, fewer hospitalisations and fewer antipsychotic trials prior to clozapine initiation showed a trend to be significantly associated with a better response to clozapine. Meta-analysis of seven studies, totalling 313 subjects, found that clozapine responders had a significantly shorter duration of illness compared to clozapine non-responders [g = 0.31; 95% confidence interval (CI) 0.06–0.56; p = 0.01]. The results imply that a delay in clozapine treatment may result in a poorer response and that a focus on prompt treatment with clozapine is warranted. [ABSTRACT FROM AUTHOR]

SUMMARY: Advocating for good physical healthcare for their patients is of the utmost importance to psychiatrists. This narrative review focuses on one part of this large goal, the topic of hyperprolactinaemia from the perspective of mental healthcare. For psychiatrists this often includes managing raised prolactin levels in the context of medication. However, they must consider the wider differentials of a raised prolactin level and the possible impact of treatments. For that reason, in this review we start with an overview of prolactin physiology before considering hyperprolactinaemia both in the context of antipsychotic therapy and its wider differentials, including prolactinoma. Investigation and management are considered and key practice points developed. [ABSTRACT FROM AUTHOR]

Negative symptoms of schizophrenia remain a major therapeutic challenge. The progress in the conceptualization and assessment is not yet fully reflected by treatment research. Nevertheless, there is a growing evidence base regarding the effects of biological and psychosocial interventions on negative symptoms. The importance of the distinction between primary and secondary negative symptoms for treatment selection might seem evident, but the currently available evidence remains limited. Good clinical practice is recommended for the treatment of secondary negative symptoms. Antipsychotic treatment should be optimized to avoid secondary negative symptoms due to side effects and due to positive symptoms. For most available interventions, further evidence is needed to formulate sound recommendations for primary, persistent, or predominant negative symptoms. However, based on currently available evidence recommendations for the treatment of undifferentiated negative symptoms (including both primary and secondary negative symptoms) are provided. Although it has proven difficult to formulate an evidence-based recommendation for the choice of an antipsychotic, a switch to a second-generation antipsychotic should be considered for patients who are treated with a first-generation antipsychotic. Antidepressant add-on to antipsychotic treatment is an option. Social skills training is recommended as well as cognitive remediation for patients who also show cognitive impairment. Exercise interventions also have shown promise. Finally, access to treatment and to psychosocial rehabilitation should be ensured for patients with negative symptoms. Overall, there is definitive progress in the field, but further research is clearly needed to develop specific treatments for negative symptoms. [ABSTRACT FROM AUTHOR]

Aims: Antipsychotics are primarily labelled for the treatment of severe mental illness and have documented clinical utility in certain neurological disorders or palliative care. However, off-label use of antipsychotics is common and increasing, and prior studies on antipsychotic utilisation have not specifically assessed users in neurology, palliative care or general practice. We aimed to explore diagnoses associated with antipsychotic use, treatment patterns and characteristics of users without diagnoses relevant to antipsychotic treatment. Methods: Population-based study identifiying all users of antipsychotics in Denmark (pop 5.7 mio.) 1997–2018 in the Danish National Prescription Register (DNPR). Possible indications for antipsychotic therapy were evaluated using in- and outpatient contacts from the DNPR. Users were divided hierarchically into six groups: severe mental disorders (schizophrenia, bipolar-spectrum disorders), chronic mental disorders (dementias, mental retardation, autism), other mental disorders (depression-spectrum, anxiety and personality disorders, etc.), selected neurological diseases, cancer and antipsychotic users without any of these diagnoses. This last group was characterised regarding demographics, antipsychotic use, health care utilisation and likely antipsychotic treatment initiator in 2018. Results: Altogether, 630 307 antipsychotic users were identified, of whom 127 649 had filled prescriptions during 2018. Users without diagnoses relevant to antipsychotic treatment comprised of the largest group (37%), followed by schizophrenia and bipolar-spectrum disorders (34%), other mental disorders (15%), dementia, autism and mental retardation (11%), cancer (2.2%) and neurological diagnoses (2.0%). Of 37 478 incident users in 2018, 39% had no diagnosis relevant to antipsychotic treatment, 7.9% had major depression, 7.7% neurotic/stress-related disorders and 7.5% dementia. Quetiapine was most commonly used, both overall (51%) and among users without diagnoses relevant to antipsychotic treatment (58%). Of 14 474 incident users in 2018 without diagnoses relevant to antipsychotic treatment, treatment was most likely initiated by a general practitioner (65%), with only 17% seeing a psychiatrist during the following year. As many as 18% of patients with adjustment disorders and 14% of those without relevant diagnoses for antipsychotic use, remained on antipsychotic treatment 5 years after their first prescription. Conclusions: Over one-third of antipsychotic users in Denmark did not have psychiatric, neurological or cancer diagnoses as possible indications for antipsychotic therapy. Many antipsychotics are initiated or prescribed in general practice, and a concerningly large subgroup without documented diagnoses relevant for antipsychotics continued to receive them. Rational prescribing, adequate side effect monitoring and further research into reasons for the observed antipsychotic use patterns and their risk–benefit ratio are needed. [ABSTRACT FROM AUTHOR]

Introduction An under-recognized life-threatening adverse effect of clozapine is the gastrointestinal hypomotility. It represents a serious problem. Clozapine is an atypical antipsychotic which commonly produces ileus. The risk is higher when we associate clozapine to drugs, such us anticholinergic and tricyclic. Ileus can produce the death in our patients, therefore we will check constipation in our daily clinical practice as a measure to avoid these side effectS. Methods We looked through Medline for articles published since 2005 regarding Clozapine and Ileus. We will present the case of a patient who developed Ileus as the side effect of clozapine. Results Constipation is very common in patients with schizophrenia (until 50%). Risk factors developing ileus in psychotic patients are: women, age, anticholinergic drugs, first generation of antipsychotics, clozapine, opioids and tricyclic antidepressants. Taking into account that this side effect can be mortal some recommendations that can reduce gastrointestinal hipomotility in this population are: a high fiber diet, exercise and the use of a softening laxative. In the case a patient treated with clozapine suffers from ileus we should shift the clozapine to aripiprazole or Amisulpride treatment. Moreover, we can use prokinetic drugs and surgery in the most complicated cases. Then, clozapine can be introduced after the ileus problem has been solved. Conclusion 1 Gastrointestinal hypomotility has a high prevalence in psychotic treatments. 2 Avoiding the use of other drugs that produce constipation. 3 Offer advice to avoid the constipation. 4 If ileus is present, stop the clozapine treatment and shift it to aripiprazole or Amisulpride.

Introduction: Oral anti-psychotic medication prescribed in primary care is a major treatment in mental illness. Since 2014 most 2nd generation anti-psychotics agents have been available through generic prescription. In 2017_18 certain generic mediations were subject to substantial price increases. Objectives: Quantify impact of changes in unit costs in primary care for main anti-psychotic medications on overall resources used and see whether this adverse situation was continuing. Methods: Monthly prescribing in primary care was consolidated by converting quantity amounts to total defined daily doses (DDD) using the factors published by WHO/ATC. Results: In 2018_19,10 million prescriptions containing 136 million DDD at costs of £110 million average £0.81/DDD were issued in primary care. The unforeseen price rises in 2017_18 caused a sharp increase in overall prices and had not reduced to the expected levels by 3rd quarter of 2019 as shown in Figure 1. Trend in average unit price in Figure 2 shows the unexpected price increases, now being reduced in Quetiapine and Olanzapine. However price increases in Chlorpromazine, Haloperidol, Amisulpride and Risperidone continue. If lowest average quarterly unit price of each medication in last 3 years are taken as benchmarks, the total costs difference between actual unit costs and the total volume prescribed multiplied by benchmark was £180 million in 3 years, 80% above the expected costs. This the equivalent to around £100/year/patient a significant sum. Conclusions: While the growth generic medication brings substantial cost advantages it also brings significant risks in supply and cost forecasting, and these rapid changes can put pressure on clinical behaviour and so patient outcomes.

Background: Delusional infestation is a condition at the interface of tactile and visual hallucinations and delusions. Individuals with this condition hold the fixed and false belief that their body or their environment is infested with parasites, insects or other organisms. Aims: There are no guidelines or publications detailing the psychological assessment, formulation, intervention and evaluation of this presentation. This paper aims to address this gap. Method: Single case experimental design methodology was employed to evaluate the use of cognitive behavioural therapy (CBT) for delusional infestation in a 70-year-old male who was intolerant of anti-psychotic medication. 'Tom' had a large, mature infarct in the middle cerebral artery territory as well as a left posterior parietal infarct post-stroke, which may have precipitated his symptoms. After a baseline period of 3 weeks, Tom received eight sessions of CBT based on the model by Collerton and Dudley (2004). Results: Post-intervention, there was a reliable improvement on clinical measures as well as a large reduction in distress levels, which was maintained at 3-month follow-up. The conviction in the belief that the infestation was real did not shift. Conclusion: This case demonstrated the potential for the use of CBT to address distress related to delusional infestation. This work is discussed in relation to post-stroke psychosis, psychological therapies with older adults, and suggestions are made for future research. [ABSTRACT FROM AUTHOR]

Background: Poor response to dopaminergic antipsychotics constitutes a major challenge in the treatment of psychotic disorders and markers for non-response during first-episode are warranted. Previous studies have found increased levels of glutamate and γ-aminobutyric acid (GABA) in non-responding first-episode patients compared to responders, but it is unknown if non-responders can be identified using reference levels from healthy controls (HCs). Methods: Thirty-nine antipsychotic-naïve patients with first-episode psychosis and 36 matched HCs underwent repeated assessments with the Positive and Negative Syndrome Scale and 3T magnetic resonance spectroscopy. Glutamate scaled to total creatine (/Cr) was measured in the anterior cingulate cortex (ACC) and left thalamus, and levels of GABA/Cr were measured in ACC. After 6 weeks, we re-examined 32 patients on aripiprazole monotherapy and 35 HCs, and after 26 weeks we re-examined 30 patients on naturalistic antipsychotic treatment and 32 HCs. The Andreasen criteria defined non-response. Results: Before treatment, thalamic glutamate/Cr was higher in the whole group of patients but levels normalized after treatment. ACC levels of glutamate/Cr and GABA/Cr were lower at all assessments and unaffected by treatment. When compared with HCs, non-responders at week 6 (19 patients) and week 26 (16 patients) had higher baseline glutamate/Cr in the thalamus. Moreover, non-responders at 26 weeks had lower baseline GABA/Cr in ACC. Baseline levels in responders and HCs did not differ. Conclusion: Glutamatergic and GABAergic abnormalities in antipsychotic-naïve patients appear driven by non-responders to antipsychotic treatment. If replicated, normative reference levels for glutamate and GABA may aid estimation of clinical prognosis in first-episode psychosis patients. [ABSTRACT FROM AUTHOR]

Background: Although clozapine is often discontinued, there is a paucity of guidelines and evidence on treatment options after clozapine discontinuation. Moreover, it is currently unknown whether reinstating clozapine in patients formerly using clozapine should be avoided.Aims: To compare the real-world effectiveness of antipsychotics after clozapine cessation.Method: From Finnish registry data (1995-2017), we identified 2250 patients with schizophrenia who had been using clozapine for ≥1 year before treatment cessation. The primary analysis consisted of adjusted within-individual analyses of psychiatric ward readmission owing to psychosis and treatment failure. Secondary analyses concerned between-individual mortality differences.Results: Compared with no use of antipsychotics, risk of psychiatric ward readmission was lowest for reinitiation of clozapine (adjusted hazard ratio (aHR) 0.49; 95% CI 0.40-0.61; P < 0.0001), oral olanzapine (aHR 0.58; 95% CI 0.48-0.71; P < 0.0001) and antipsychotic polypharmacy (aHR 0.62; 95% CI 0.53-0.72; P < 0.0001). Risk of treatment failure was lowest for aripiprazole long acting injectable (aHR 0.42; 95% CI 0.27-0.65; P < 0.0001), reinitiation of clozapine (aHR 0.49; 95% CI 0.43-0.57; P < 0.0001) and oral olanzapine (aHR 0.69; 95% CI 0.61-0.77; P < 0.0001). Mortality risk was lowest for reinitiation of clozapine (aHR 0.18; 95% CI 0.09-0.36; P < 0.0001) and oral olanzapine (aHR 0.26; 95% CI 0.17-0.40; P < 0.0001).Conclusions: Clozapine and olanzapine are the most effective and safest treatment options in those discontinuing clozapine for undefined reasons. Clozapine should therefore be reconsidered in patients with schizophrenia who previously discontinued this compound. [ABSTRACT FROM AUTHOR]

Background: Cognitive behavioural therapy (CBT) for psychosis currently yields modest outcomes and must be improved. Attachment imagery may be an effective means of reducing severity of paranoid beliefs and associated affect. Experimental studies have demonstrated these effects in non-clinical groups. The impact in clinical populations remains untested. Aims: This study assessed the impact of a brief attachment imagery task on paranoia and mood, in two people with a diagnosis of schizophrenia. Method: Two single case studies are presented. Both participants were working age adults with persecutory delusions. The study utilised an A-B-A design. Participants were recruited for a 6-week period, with a 2- and 3-week baseline respectively, 1-week intervention phase, and follow-up phase matched to duration of baseline. Trait paranoia and attachment were measured at the start of the baseline. State paranoia and affect were measured daily over the 6-week period. Results: For both participants, the baseline phase was characterised by high and variable levels of paranoia, which reduced during the intervention phase, with a return to baseline scores at follow-up. We found a similar pattern for negative affect, and the reverse pattern for positive affect. Conclusions: Attachment imagery may function as an effective emotion regulation strategy for people with psychosis. Continued use is likely to be needed to maintain gains. This brief task could prove valuable to people needing skills to manage paranoia and mood, and give clinicians confidence that people can manage short-term distress in CBT for psychosis, for example when addressing past trauma.

People with severe mental illness (SMI) have numerous risk factors that may predispose them to food insecurity (FI); however, the prevalence of FI and its effects on health are under-researched in this population. The present study aimed to describe the prevalence of FI and its relationship to lifestyle factors in people with SMI. This cross-sectional study recruited people with SMI receiving long-acting injectable (LAI) antipsychotic medication from community services at three sites in Sydney, Australia. Assessments were completed on physical health and lifestyle factors. χ2 Tests, independent-samples t tests and binary logistic regression analyses were calculated to examine relationships between lifestyle factors and FI. In total, 233 people completed the assessments: 154 were males (66 %), mean age 44·8 (sd 12·7) years, and the majority (70 %) had a diagnosis of schizophrenia. FI was present in 104 participants (45 %). People with FI were less likely to consume fruits (OR 0·42, 95 % CI 0·24, 0·74, P = 0·003), vegetables (OR 0·39, 95 % CI 0·22, 0·69, P = 0·001) and protein-based foods (OR 0·45, 95 % CI 0·25, 0·83, P = 0·011) at least once daily, engaged in less moderate to vigorous physical activity (min) (OR 0·997, 95 % CI 0·993, 1·000, P = 0·044), and were more likely to smoke (OR 1·89, 95 % CI 1·08, 3·32, P = 0·026). FI is highly prevalent among people with SMI receiving LAI antipsychotic medications. Food-insecure people with SMI engage in less healthy lifestyle behaviours, increasing the risk of future non-communicable disease. [ABSTRACT FROM AUTHOR]

Objective: From case reports, haloperidol administration has been associated with QTc prolongation, torsades de pointes, and sudden cardiac death. In a vulnerable population of critically ill patients after cardiac surgery, however, it is unclear whether haloperidol administration affects the QTc interval. Thus, the aim of this study is to explore the effect of haloperidol in low doses on this interval.Method: This retrospective cohort study was performed on a cardio-surgical intensive care unit (ICU), screened 2,216 patients and eventually included 68 patients with delirium managed with oral and intravenous haloperidol. In this retrospective analysis, electrocardiograms were taken prior and within 24 h after haloperidol administration. The effect of haloperidol on QTc was determined with a Person correlation, and inter-group differences were measured with new long QT comparisons.Results: In total, 68 patients were included, the median age was 71 (64-79) years and predominantly male (77%). Haloperidol administration followed ICU admission by three days and the cumulative dose was 4 (2-9) mg. As a result, haloperidol administration did not affect the QTc (r = 0.144, p = 0.23). In total, 31% (21/68 patients) had a long QT before and 27.9% (19/68 patients) after haloperidol administration. Only 12% (8/68 patients) developed a newly onset long QT. These patients were not different in the route of administration, cumulative haloperidol doses, comorbidities, laboratory findings, or medications.Significance Of Results: These results indicated that low-dose intravenous haloperidol was safe and not clinically relevant for the development of a newly onset long QT syndrome or adverse outcomes and support recent findings inside and outside the ICU setting.

Aim: Compared with the general population, individuals with schizophrenia have a higher risk of periodontal disease, which can potentially reduce their life expectancy. However, evidence for the early development of periodontal disease in schizophrenia is scant. The current study investigated risk factors for periodontal disease in patients newly diagnosed with schizophrenia. Methods: We identified a population-based cohort of patients in Taiwan with newly diagnosed schizophrenia who developed periodontal disease within 1 year of their schizophrenia diagnosis. Treatment with antipsychotics and other medications was categorised according to medication type and duration, and the association between medication use and the treated periodontal disease was assessed through logistic regression. Results: Among 3610 patients with newly diagnosed schizophrenia, 2373 (65.7%) had an incidence of treated periodontal disease during the 1-year follow-up. Female sex (adjusted odds ratios [OR] 1.40; 95% confidence interval [CI] 1.20–1.63); young age (adjusted OR 0.99; 95% CI 0.98–0.99); a 2-year history of periodontal disease (adjusted OR 2.45; 95% CI 1.84–3.26); high income level (adjusted OR 2.24; 95% CI 1.64–3.06) and exposure to first-generation (adjusted OR 1.89; 95% CI 1.54–2.32) and secondary-generation (adjusted OR 1.33; 95% CI 1.11–1.58) antipsychotics, anticholinergics (adjusted OR 1.24; 95% CI 1.03–1.50) and antihypertensives (adjusted OR 1.91; 95% CI 1.64–2.23) were independent risk factors for periodontal disease. Hyposalivation – an adverse effect of first-generation antipsychotics (FGAs) (adjusted OR 2.00; 95% CI 1.63–2.45), anticholinergics (adjusted OR 1.27; 95% CI 1.05–1.53) and antihypertensives (adjusted OR 1.90; 95% CI 1.63–2.22) – was associated with increased risk of periodontal disease. Therefore, hypersalivation due to FGA use (adjusted OR 0.72; 95% CI 0.59–0.88) was considered a protective factor. Conclusions: The current study highlights that early prevention of periodontal disease in individuals with schizophrenia is crucial. Along with paying more attention to the development of periodontal disease, assessing oral health regularly, helping with oral hygiene, and lowering consumption of sugary drinks and tobacco, emphasis should also be given by physicians to reduce the prescription of antipsychotics to the extent possible under efficacious pharmacotherapy for schizophrenia.

Background: The association between schizophrenia and decreased vitamin D levels is well documented. Low maternal and postnatal vitamin D levels suggest a possible etiological mechanism. Alternatively, vitamin D deficiency in patients with schizophrenia is presumably (also) the result of disease-related factors or demographic risk factors such as urbanicity. Methods: In a study population of 347 patients with psychotic disorder and 282 controls, group differences in vitamin D concentration were examined. Within the patient group, associations between vitamin D, symptom levels and clinical variables were analyzed. Group × urbanicity interactions in the model of vitamin D concentration were examined. Both current urbanicity and urbanicity at birth were assessed. Results: Vitamin D concentrations were significantly lower in patients (B = −8.05; 95% confidence interval (CI) −13.68 to −2.42; p = 0.005). In patients, higher vitamin D concentration was associated with lower positive (B = −0.02; 95% CI −0.04 to 0.00; p = 0.049) and negative symptom levels (B = −0.03; 95% CI −0.05 to −0.01; p = 0.008). Group differences were moderated by urbanicity at birth (χ2 = 6.76 and p = 0.001), but not by current urbanicity (χ2 = 1.50 and p = 0.224). Urbanicity at birth was negatively associated with vitamin D concentration in patients (B = −5.11; 95% CI −9.41 to −0.81; p = 0.020), but not in controls (B = 0.72; 95% CI −4.02 to 5.46; p = 0.765). Conclusions: Lower vitamin D levels in patients with psychotic disorder may in part reflect the effect of psychosis risk mediated by early environmental adversity. The data also suggest that lower vitamin D and psychopathology may be related through direct or indirect mechanisms. [ABSTRACT FROM AUTHOR]

Background: There is uncertainty about the incidence of breakthrough psychosis in treatment adherent patients, and the role that factors, such as cumulative antipsychotic exposure, play in this phenomenon. Methods: In a nationwide cohort of individuals treated for schizophrenia-spectrum disorders in Finland between 1 January 1996 and 31 December 2015, 'Breakthrough Psychosis on Antipsychotic Maintenance Medication' (BAMM) was defined as hospitalization for psychosis despite ongoing continuous treatment with long-acting injectable antipsychotics (LAIs) or oral antipsychotics (OAPs) for ⩾8 weeks. Incidence rates, survival curves, and risk factors were presented. Results: In a cohort of 16 031 continuous LAI treatment episodes with virtually assured adherence [median duration = 441 days, interquartile range (IQR) = 155–1277], BAMM incidence was 31.5%. For 42 867 OAPs treatment episodes (median duration = 483 days, IQR = 167–1491), for whom adherence was modeled by the PRE2DUP method, BAMM incidence was 31.1%. Factors related to illness instability at treatment onset were associated with BAMM, although median time to BAMM was 291 days (IQR = 121–876) for LAIs and 344 days (IQR = 142–989) for OAPs, and 27.4% (N = 1386) of the BAMM events in the LAI, and 32.9% (N = 4378) in the OAP group occurred despite >1 year since last hospitalization at treatment onset. Cumulative antipsychotic exposure was not a consistent risk factor. Conclusion: BAMM was relatively common even when adherence was confirmed with LAIs. Illness instability at treatment onset accounted for most cases, but relapse after years of continuous treatment was still prevalent. There was insufficient evidence to support causality between cumulative antipsychotic exposure and BAMM. Future research needs to address the role of symptom severity and neurobiology in BAMM.

SUMMARY: This article considers sexuality in older adults and the associated stereotypes and stigmas that lead to this area being underappreciated. Normal physiological changes in ageing are discussed and how they can cause sexual dysfunction. The elderly population has a higher burden of comorbid physical illness and this review considers evidence on the interplay between physical health and sexual health. Mental illness is also strongly linked with sexual functioning and is discussed, as is the evidence on psychotropics and sexual side-effects. Attitudes on sexuality in long-term care settings are highlighted and approaches to managing sexual disinhibition are included. [ABSTRACT FROM AUTHOR]

Objectives: There is a paucity of available research to guide clinical practice in delusional disorder (DD), particularly in late life. This study aimed to evaluate antipsychotic use and treatment outcomes in patients with DD aged 65 years and older. Secondarily, we sought to examine associated clinical features and socio-demographic variables.Design and Setting: This descriptive study reviewed all consecutive cases of DD referred to an Australian old age psychiatry service over a 12-year period. Fifty-five patients were assessed in the inpatient and/or community setting, with data verified from a review of all individual medical records.Measurements: Data were collected with respect to antipsychotic use, outcomes, and clinical features. Socio-demographic variables of DD cases were compared to a non-matched comparison group (n=278) and an age and gender matched comparison group with a 1:1 ratio (n=55).Results: The predominant type of DD was persecutory (87%). Non-prominent hallucinations were experienced by 18%, and depressive symptoms occurred in 22%. There was a statistically significant association between having DD and social isolation (χ2= 11.04 (DF=1) p<0.001; McNemar's test p<0.001). Atypical antipsychotic medication was prescribed in 32 cases, with follow-up permitted in 51 of the 55 cases (mean duration 36.6 months). Sustained recovery occurred in 20%, and improvement in an additional 35% of the study sample. Four patients subsequently developed dementia, and two developed mild cognitive impairment.Conclusions: Clinical improvement, including sustained recovery, occurred in more than half of those with late life DD. The majority of those who improved (96%) received atypical antipsychotics. [ABSTRACT FROM AUTHOR]

SUMMARY: Second-generation antipsychotic medications (SGAs) have advanced the treatment of schizophrenia over the past 30 years. However, a number of potentially life-threatening cardiac side-effects associated with these treatments concern and can discourage prescribers from administering these evidence-based treatments. This review provides a practical, psychiatrist-oriented understanding of the relative frequencies, mechanisms, investigations and treatments associated with these cardiac toxicities. We aim to highlight that these are relatively rare complications of an effective class of drug and to promote the advantages of early involvement of cardiologists in the psychiatric multidisciplinary team to guide the investigation and management of these conditions. LEARNING OBJECTIVES: After reading this article you will be able to: • understand the relative incidence of cardiotoxic side-effects of the various SGAs • perform preliminary investigations to diagnose the common cardiotoxic side-effects of SGAs • understand the treatments for these cardiac side-effects and the role of cardiologists involved the care of these patients.

Background: Around 30% of patients with schizophrenia are considered treatment resistant (TRS). Only around 40% of TRS patients respond to clozapine. Long acting injectable antipsychotics could be a useful augmentation strategy for nonresponders. Methods: We conducted a multicenter, observational, naturalistic, retrospective, 6-month mirror-image study to evaluate the efficacy and tolerability of clozapine and paliperidone palmitate association in 50 patients with TRS and other psychotic disorders. Clinical outcomes and side effects were systematically assessed. Results: Six months after starting the combined treatment, participants showed a significant relief of symptoms, decreasing the Brief Psychiatric Rating Scale total score from 18.32-7.71 to 7.84-5.16 (p < 0.001). The number of hospitalizations, the length of hospital stays and the number of visits to emergency services also decreased, while an increase of the functionality was observed (Personal and Social Performance total score increased from 46.06-118.7 to 60.86-18.68, p < 0.001). There was also a significant decrease in the number and severity of side effects with the combination therapy, decreasing the Udvalg for Kliniske Undersogelser total score from 10.76-8.04 to 8.82-6.63 (p = 0.004). Conclusions: This study provides the first evidence that combining clozapine with paliperidone palmitate in patients with TRS and other psychotic disorders could be effective and safe, suggesting further research with randomized controlled trials of augmentation strategies for clozapine nonresponder patients. Policy Significance Statement: Patients with psychotic disorders such as schizophrenia show a variable response to antipsychotic treatments. Around 30% of patients are considered treatment resistant, indicated by insufficient symptom control to at least two different drugs. In these resistant cases, clozapine should be indicated, as it has shown to be superior to other options. However, only 40%of patients respond to clozapine, being necessary to establishwhich treatments could best potentiate clozapine action. Combining clozapine with long acting injectable antipsychotics, and particularly paliperidone palmitate, could be a useful strategy. We conducted a multicenter study of 50 patients with treatment-resistant schizophrenia and other psychotic disorders comparing the efficacy and tolerability in the 6month-period prior and after starting the clozapine and paliperidone palmitate association. Our study suggests that this combination could be effective and safer, laying the groundwork for future clinical trials with this combination. [ABSTRACT FROM AUTHOR]

Background. There is consistent evidence that theory of mind (ToM) is impaired in schizophrenia (SZ); however, it remains unclear whether such deficits are trait- or state-dependent. We evaluated ToM in patients with schizophrenia spectrum disorders (SSDs), their healthy firstdegree relatives, and controls to test its suitability as an endophenotypic marker. We also studied the modifying effect of markers of clinical and genetic liability to SZ (schizotypy and genetic variability in the oxytocin receptor gene: OXTR) on ToM in healthy individuals. Methods. The sample included 38 stable SSD patients, 80 unaffected first-degree relatives, and 81 controls. ToM was assessed using the Hinting Task (HT) and schizotypy via the Schizotypal Personality Questionnaire-Brief (SPQ-B), which generates interpersonal (SPQ-IP), cognitiveperceptual (SPQ-CP), and disorganization (SPQ-D) scores. The polymorphism rs53576 of OXTR was genotyped. Results. Patients presented poorer HT performance than relatives and controls (p = 0.003 and p < 0.001). High SPQ-IP and SPQ-CP scores correlated with poorer ToM performance in relatives (p = 0.010 and p = 0.030), but not in controls. OXTR was not associated with HT scores, but it showed amodifying effect within controls; high SPQ-CP was related toHT poorer performance conditional to GG genotype (p = 0.007). Conclusions. ToM deficits were present in patients but not in unaffected relatives or controls. However, our data indicate the usefulness of clinical and genetic liability markers to characterize differences in ToM abilities within healthy individuals. Then, the observed link between ToM and SZ liability suggests the putative role of ToM as an endophenotypic marker. Nevertheless, new analyses in larger samples are needed. [ABSTRACT FROM AUTHOR]

The release of the Telepsychiatry Operational Guidelines 2020 in India, during the COVID-19 pandemic, is a relief for both clinicians and patients. These guidelines embark on initiating and executing naive and recently started telepsychiatry services in India. The document is aligned with other ethical regulations, policies, laws and the 2020 Telemedicine Practice Guidelines in India. This paper discusses a few points about the broader applicability of the guideline for the benefit of humankind in the prevailing healthcare crisis. The guidelines may be extrapolated in policy-making for telepsychiatry services in other low- and middle-income countries sharing a similar socioeconomic, cultural and political milieu.

Objective: The primary objective was to assess the reasons for antipsychotics switch to amisulpide and to evaluate the outcome at 6±1 months following the switch from any antipsychotic drug(s) to amisulpride (Solian®). Methods: This is an open, non-randomized, multicentric, retrospective, non-interventional study that included 1165 subjects who were already stabilized on amisulpride for at least 6±1 months. These patients were previously switched from other antipsychotic to Solian®. Data were collected retrospectively on the patients’ status 6±1 months ago and their present status. Results: Reasons for switching previous antipsychotic treatment: inadequate control of symptoms in 79.3% of the patients, relapse of the disease under treatment 54.5%, adverse reactions 61.9%, reduced compliance 49.1%, comorbities 7.7%, patients request 28%, family request 24.5%, high cost 1.8%. Reasons for choosing Solian®: quality of life improvement 20.3%, cognitive function preservation 18.7%, better efficacy on positive symptoms 18.7%, better efficacy on negative symptoms 15.1%, low risk of extrapyramidal symptoms 12.3%, reduced weight gain 9.8%, minimal interactions with other drugs 4.2%. The compliance was significantly improved (61%), moderately improved (16%), unchanged (7.6%). Adverse reactions were significantly improved (53.5%), moderately improved (18.5%), unchanged (8.9%), minimum worsening (0.2%), medium worsening (0.1%). The efficacy was significantly improved (69.8%), moderately improved (19.2%), unchanged (2.2%), minimum worsening (0.1%). Conclusions: The main reasons for antipsychotic switch were the inadequate control of symptoms, relapse of the disease under treatment and adverse reactions. Psychiatrists’ evaluation of the switch outcome at 6±1 months following the switch underlined significant improvement of compliance, adverse reactions and treatment efficacy. [ABSTRACT FROM AUTHOR]
