BMJ Open 2023; 13:e071984. [PMID: 37977861 PMCID: PMC10660841 DOI: 10.1136/bmjopen-2023-071984] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/19/2023] [Accepted: 10/30/2023] [Indexed: 11/19/2023] Open
Abstract
OBJECTIVES To assess the current evidence on the potential of digital health interventions (DHIs) to improve adherence to oral antipsychotics among patients with schizophrenia by assessing the methodologies, feasibility and effectiveness of DHIs as well as the perceptions of relevant stakeholders. DESIGN The scoping review was conducted based on the methodologies outlined by Levac et al and reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews guidelines. DATA SOURCES PubMed, Embase, Web of Science, Scopus, CINAHL, PsycINFO and the Cochrane Library were searched in August 2023 to identify relevant publications from the previous decade. ELIGIBILITY CRITERIA Studies published in English focused on improving medication adherence among adult patients with schizophrenia or schizoaffective disorder via DHIs were selected. Protocols, editorials, comments, perspectives, reviews, correspondence and conference abstracts were excluded. DATA EXTRACTION AND SYNTHESIS The extracted data included general information about the study, framework, participants, features and strategies of DHIs, measurement tools for adherence used, and main findings. RESULTS In total, 64 studies were included in the qualitative synthesis. Features used in DHIs to improve medication adherence included phone calls, text messages, mobile apps, sensors, web-based platforms and electronic devices. Strategies included medication reminders and monitoring, providing medication-related information and suggestions, other illness management suggestions and individual support. Texting and mobile apps were commonly used as medication reminders and monitoring methods. Additionally, the use of sensors combined with other digital technologies has garnered significant attention. All the interventions were considered acceptable and feasible, and several were assessed in pilot trials. Preliminary findings suggest that DHIs could enhance medication adherence in patients with schizophrenia. However, further validation of their effectiveness is required. CONCLUSION DHIs are a promising approach to enhancing medication adherence among patients with schizophrenia. Future interventions should be interactive, focusing on user preference, experience and privacy.

The Effect of Longer Dosing Intervals for Long-Acting Injectable Antipsychotics on Outcomes in Schizophrenia. Neuropsychiatr Dis Treat 2023; 19:531-545. [PMID: 36915909 PMCID: PMC10008005 DOI: 10.2147/ndt.s395383] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/29/2022] [Accepted: 01/12/2023] [Indexed: 03/16/2023] Open
Abstract
Medication nonadherence in schizophrenia can have serious implications including relapses and hospitalization. Long-acting injectable (LAI) antipsychotics require fewer administrations, while ensuring sustained medication coverage. In this review, we summarize the expected real-world benefits of longer dosing intervals in the management of schizophrenia. LAIs are associated with improved clinical outcomes of less frequent relapses and reduced functional impairment, encouraging patients to regain control of their lives. Aripiprazole lauroxil and paliperidone palmitate three-monthly (PP3M) LAIs have longer dosing intervals of 2-3 months and provide improved outcomes in patients with schizophrenia. Paliperidone palmitate six-monthly (PP6M) LAI provides the longest dosing interval, twice-yearly dosing, among existing LAIs. Decreasing the frequency of LAI administrations has the potential to reduce occurrence of serious outcomes associated with poor medication adherence. By eliminating the need for daily oral antipsychotic dosing, LAIs could increase the likelihood of patient acceptance, decrease stigma, and promote self-esteem. Longer intervals of medication coverage may be desirable for patients with higher risk of relapse including adults with recent-onset schizophrenia, those living in circumstances that may deprive them of regular access (eg, homeless), those that are in transitions between care settings or to reduce interpersonal contact during public health emergencies (eg, COVID-19 pandemic).

Abstract
INTRODUCTION Access to mental health services is a challenge, especially for young people who are over-represented in the unemployment and poverty index in South Africa. Therefore, continuing care is a problem after hospital discharge for young people with first-episode psychosis (FEP) due to a lack of clinical engagement and follow-up, for which they need support, including financial, to improve their outcomes. This pilot randomised control trial (RCT) aims to assess the feasibility and acceptability of financial support, in the form of an unconditional cash transfer (UCT), among young patients with FEP to prevent relapse. METHODS AND ANALYSIS This study will use a 1:1 ratio two-arm open-label pilot RCT of 60 young participants (18-29 years) with FEP in remission, who will be recruited from specialised psychiatric facilities in KwaZulu-Natal Province, South Africa. This study will implement an UCT and assess its feasibility, acceptability and preliminary clinical outcomes (ie, medication adherence, relapse, quality of life, personal and social function). The follow-up time will be 3 months, the outcomes being measured at baseline, months 1 and 3. Descriptive and conventional content analysis will be done for quantitative and qualitative data, respectively. ETHICS AND DISSEMINATION The study obtained provisional approval from the Biomedical Research Ethics Committee at the University of KwaZulu-Natal(#BREC/00004117/2022). Also is registered on the South African National clinical trial registry (#DOH-27-092022-5894) and approved by the KwaZulu-Natal department of health (#NHRD Ref: KZ_2002209_033). The results from this investigation will be actively disseminated through peer-reviewed journal publications, conference presentations and stakeholder engagement. TRIAL REGISTRATION NUMBER DOH-27-092022-5894.

Abstract
BACKGROUND The coronavirus disease 2019 (COVID-19) pandemic has resulted in a total upending of our daily lives. While anxiety and depression were frequently reported among the general population, the pandemic's impact on patients with mental health problems remains unknown. METHODS A cross-sectional questionnaire survey involving 1,166 patients was conducted at one psychiatric hospital and one mental health clinic. RESULTS Symptom deterioration was reported in 23% to 34% of the patients and 9% to 20% reported increase in drug dosage. No significant differences were reported in these items among diagnostic categories. Patients with F3 (mood disorders) reported more psychological stress during the pandemic's beginning and during the emergency. Patients with F2 (schizophrenia, schizotypal, and delusional disorders) did online shopping and meetings less frequently, and reported poorer adherence of 3C's, while mask management was stricter in patients with F4 (neurotic, stress-related, and somatoform disorders). Symptom deterioration was significantly associated with increase in drug dosage, new physical symptoms, anxiety unrelated to COVID-19, stress at the beginning of pandemic, stress during the 'state of emergency', poor adaptability to environmental change, daily life changes, decrease in sleeping time, and decrease in time spent outside. CONCLUSION One third of patients reported symptom deterioration during the pandemic, which was associated with stress and daily life changes. Patients with good adaptability to environmental changes might resilient against symptom deterioration. Providing continuous support to help patients manage their daily life in this COVID-19 era may minimize the risk of symptom deterioration.

CLINICAL PSYCHOPHARMACOLOGY AND NEUROSCIENCE 2021; 19:773-779.

Abstract
Objective While antipsychotics are necessary for relapse prevention in the treatment of schizophrenia in general, some minority of patients may be maintained without continuous antipsychotic treatment. However, the characteristics of such patients are not well known and previous reports have not evaluated key elements such as physical comorbidities and functioning. Methods Among 635 patients with schizophrenia who participated in a 12-year follow-up, those who were maintained without antipsychotic treatment for at least one year after the study were investigated. The patients underwent comprehensive assessments, including Positive and Negative Syndrome Scale (PANSS) for psychopathology, Cumulative Illness Rating Scale for Geriatrics (CIRS-G) for physical comorbidities, and Functional Assessment for Comprehensive Treatment of Schizophrenia (FACT-Sz), Barthel Index, and EuroQoL five dimensions (EQ5D) for function. Results Six patients were included (mean ± standard deviation age, 66.8 ± 17.4 years; 4 inpatients). The four inpatients were old (77.8 ± 4.8 years) and chronically ill (duration of illness, 49.3 ± 12.5 years) with a high PANSS score (total score, 118.0 ± 9.8; negative syndrome subscale, 41.3 ± 6.9), low functioning (FACT-Sz, 9.8 ± 3.6; Barthel Index, 8.8 ± 9.6), and serious physical comorbidities (CIRS-G, 15.5 ± 1.1). By contrast, the two outpatients were relatively young (45.0 ± 12.0 years) and clinically in good condition (PANSS total score, 44.5 ± 0.5; Barthel Index, 100 for both; EQ5D, 0.85 ± 0.04). Conclusion Although the number is limited, two types of patients with schizophrenia were identified who were free from ongoing antipsychotic treatment; 1) older chronic inpatients with serious physical comorbidities, and 2) younger outpatients with milder impairments. Future explorations are needed to identify those who will be successfully withdrawn from continuous antipsychotic treatment.

Abstract
This study aimed to identify if antipsychotic exposure in offspring is associated with psychiatric and non-psychiatric healthcare service use and work disability of their parents. This Swedish population-based cohort study was based on data comprising 10,883 individuals with schizophrenia, who had at least one identifiable parent in the nationwide registers, and their parents (N = 18,215). The register-based follow-up during 2006–2013 considered the level of antipsychotic exposure and persistence of use of the offspring, further categorized into first (FG) and second generation (SG) antipsychotics, and orals versus long-acting injections (LAIs). The main outcome measure was parental psychiatric healthcare service use, secondary outcomes were non-psychiatric healthcare use and long-term sickness absence. SG-LAI use was associated with a decreased risk (relative risks [RR] 0.81-0.85) of parental psychiatric healthcare use compared with not using SG-LAI, whereas oral antipsychotics were associated with an increased risk (RRs 1.10–1.29). Both FG- and SG-LAI use by the offspring were associated with a lower risk of long-term sickness absence (range of odds ratios 0.34–0.47) for the parents, compared with non-use of these drugs. The choice of antipsychotic treatment for the offspring may have an impact on work disability and healthcare service use of their parents.

Abstract
INTRODUCTION While patients' perspectives toward pharmacotherapy are expected to be directly influenced by their motivation and understanding of the treatment that they are currently receiving, no study has comprehensively investigated the impact of insight into illness and knowledge for the ongoing pharmacotherapy on the attitude towards drug treatment among patients with schizophrenia. MATERIALS AND METHODS One hundred forty-eight Japanese outpatients diagnosed with schizophrenia, according to the International Classification of Diseases 10th edition, were included (mean±SD age, 47.3±12.4 years; 90 men (60.8%)). Attitudes toward antipsychotic treatment and insight into illness were assessed with the Drug Attitude Inventory-10 (DAI-10) and the VAGUS, respectively. In addition, a multiple-choice questionnaire that was designed to examine patients' knowledge about therapeutic effects, types, and implicated neurotransmitters of antipsychotic drugs they were receiving was utilized. RESULTS The mean±SD of DAI-10 score was 4.7±4.2. The multiple regression analysis found that lower Positive and Negative Syndrome Scale (PANSS) scores, higher VAGUS scores, and longer illness duration were significantly associated with higher DAI-10 scores (β=-0.226, P=0.009; β=0.250, P=0.008; β=0.203, P=0.034, respectively). There was a significant difference in the DAI-10 scores between the subjects who gave more accurate answers regarding the effects of their primary antipsychotic and those who did not (mean±SD, 5.57±4.38 vs 4.13±4.04, P=0.043); however, this finding failed to survive the multiple regression analysis. CONCLUSION Better insight into illness and treatment, lower illness severity, longer illness duration, and possibly greater knowledge about the therapeutic effects of medications may lead to better attitudes towards pharmacotherapy among patients with schizophrenia, which has an important implication for this typically chronic mental condition requiring long-term antipsychotic treatment to sustain stability.

Abstract
OBJECTIVE Long-acting depot preparations of antipsychotics are the mainstay of treatment for patients with schizophrenia who show nonadherence to their medications. Olanzapine pamoate is one of the recently approved long-acting depot psychotropic preparations that have shown its efficacy both in clinical trials and in clinical uses against the illness. However, emerging literature indicates toward a cluster of adverse effects known as postinjection delirium/sedation syndrome (PDSS). METHODS We here present a case of PDSS in a woman with paranoid schizophrenia. After maintaining well for almost 1½ years, she developed PDSS at her 31st scheduled long-acting olanzapine injection. RESULTS Several features of PDSS including its mechanism and course have been discussed. CONCLUSIONS More research is necessary to understand the syndrome and the association between PDSS and long-acting olanzapine injection. Clinicians should keep in mind that PDSS may worsen compliance in an index patient and affect the course of the illness.

Abstract
Objective: The ACCESS treatment model offers assertive community treatment (ACT) embedded in an integrated care program to patients with severe psychotic disorders. Compared to standard care, it proved to be more effective in terms of service disengagement and other outcomes in patients with psychotic disorders over 12, 24, and 48 months. Many patients with severe mental disorders experience involuntary admissions which can be potentially traumatic. In this study, we assessed the effect of ACT on reducing involuntary admissions over an observation period of 4 years. Method: One hundred seventy-one patients treated in ACCESS were included in this study. The primary outcome was rate of involuntary admissions during 48 months. Secondary outcomes were differences between those with and without involuntary admissions in the 2 years prior to ACCESS regarding change of psychopathology, severity of illness, psychosocial functioning, quality of life, satisfaction with care, medication non-adherence, and service-disengagement. Results: Of 171 patients, 58 patients (33.9%) were involuntarily admitted to hospital in the past 2 years before entry. During the 4 years of treatment, 16 patients (9.4%) were involuntarily admitted to hospital which was a significantly lower rate compared to the 2 years before inclusion in ACCESS (p < .001). Comparing the two groups, larger improvements in severity of illness (p = .004) and functional status (p = .043) were detected in the group with no history of involuntary admissions. At 4-year follow-up, of the remaining patients, 69.2% (n = 81) were full adherent (p < .001), compared to 18.9% (n = 31) at baseline with no differences between the two groups over the study period (p = .25). Over 4 years, only 13 patients (13.2%) were service-disengaged due to non-practical reasons. Conclusions: In this long-term study, we were able to demonstrate a reduction in involuntary admissions in four treatment years compared to the 2 years prior to admission to the ACCESS model in patients with severe and mostly multiphase schizophrenia spectrum disorders and affective disorders with psychotic features. This may help prevent patients from suffering from a potentially traumatic experience during treatment in the psychiatric system.

Clinical Characteristics of Patients With Schizophrenia Who Successfully Discontinued Antipsychotics: A Literature Review. J Clin Psychopharmacol 2018; 38:582-589. [PMID: 30300291 DOI: 10.1097/jcp.0000000000000959] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 12/22/2022]
Abstract
PURPOSE/BACKGROUND Although discontinuing antipsychotics clearly increases the risk of relapse in schizophrenia, some patients remain clinically well without continuous antipsychotic treatment. However, data on the characteristics of such patients are still scarce. METHODS/PROCEDURES A systematic literature review was conducted to identify predictive factors for successful antipsychotic discontinuation in schizophrenia using PubMed (last search; June 2018) with the following search terms: (antipsychotic* or neuroleptic) AND (withdraw* or cessat* or terminat* or discontinu*) AND (schizophreni* or psychosis). The search was filtered with humans and English. Factors associated with a lower risk of relapse, when replicated in 2 or more studies with a follow-up period of 3 months or longer, were considered successful. FINDINGS/RESULTS Systematic literature search identified 37 relevant articles. Mean relapse rate after antipsychotic discontinuation was 38.3% (95% confidence interval = 16.0%-60.6%) per year. Factors associated with a lower risk of relapse were being maintained on a lower antipsychotic dose before discontinuation, older age, shorter duration of untreated psychosis, older age at the onset of illness, a lower severity of positive symptoms at baseline, better social functioning, and a lower number of previous relapses. IMPLICATIONS/CONCLUSIONS Although this literature review suggests some predictors for successful antipsychotic withdrawal in patients with schizophrenia, the very limited evidence base and unequivocally high relapse rates after discontinuation must remain a matter of serious debate for risk/benefit considerations.

Effectiveness of aripiprazole once-monthly in schizophrenia patients pretreated with oral aripiprazole: a 6-month, real-life non-interventional study. BMC Psychiatry 2018; 18:365. [PMID: 30428862 PMCID: PMC6237037 DOI: 10.1186/s12888-018-1946-x] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/19/2018] [Accepted: 10/30/2018] [Indexed: 01/01/2023] Open
Abstract
BACKGROUND In this study, the treatment of schizophrenia patients with aripiprazole once-monthly (AOM) was evaluated under real-life conditions in a naturalistic setting. METHODS This multicenter, prospective, non-interventional study included 242 patients (age = 43.1 ± 15.1 years, 55.0% male) who were monitored during 6 months of AOM treatment. Endpoints included measurements of psychopathology (Brief Psychiatric Rating Scale, BPRS) and severity of illness scales (Clinical Global Impressions-Severity, CGI-S, and -Improvement, CGI-I). Furthermore, treatment-related adverse events (TRAEs) were recorded. RESULTS At baseline, the mean BPRS total score was 54.1 ± 15.6, the mean CGI-S was 4.8 ± 0.8 and the most frequent illness category was 'markedly ill' (41.7%). Patients had been pretreated with oral aripiprazole for a mean duration of 9.7 months (SD: 22.3) and 87.9% were deemed by their clinician as "clinically stable" and for a mean of 5.9 months. The difference in global BPRS after 6 months was - 13.8 (SD: 16.0; 95% CI: [- 15.9; - 11.7]; p < 0.001). The proportion of patients with high CGI-S scores decreased and the proportion of patients with low scores increased significantly (p < 0.001, respectively). BPRS scores improved numerically especially well in younger patients ≤35 years, CGI-S scores decreased significantly more in this population. TRAEs were rare, with low incidences of extrapyramidal symptoms (2.9%) or weight increase (0.4%). CONCLUSIONS Treatment with AOM showed satisfying effectiveness in outpatients with further improvement of psychopathology after oral aripiprazole treatment for a considerable duration and even after having achieved clinically judged "stability". Our findings indicate a robust therapeutic effect of AOM and substantiate previous results from randomized controlled trials under real-world routine conditions.

Abstract
Schizophrenia has been claimed to be a "heterogeneous" disorder despite the fact that a diagnosis is made without reliable biomarkers but sorely with a constellation of "common" observable symptoms that however may be overlooked. Alternatively functional impairments are the prerequisite to make a diagnosis and may be simpler and more pragmatic to express objectively. It would then be reasonable to categorize patients according to the magnitude of psychosocial impairments, as has been done in terms of the severity of "classical" symptoms. In this context the author proposes a new paradigm in which patients with schizophrenia are classified into three functional subtypes using the anchors for the Clinical Global Impression Functioning subscale (CGI-F, adopted from the CGI) and the Functional Assessment for Comprehensive Treatment of Schizophrenia (FACT-Sz): Class 1 patients are those with no to mild functional impairments (a score of 1-3 in the CGI-F and a score of 60-100 in the FACT-Sz), Class 2 patients are those with moderate to marked impairments (4 or 5 in the CGI-F and 40-59 in the FACT-Sz), and Class 3 patients are those with severe to most severe impairments (6 or 7 in the CGI-F 6,7 and 0-39 in the FACT-Sz). The author has no intention to ignore the importance of other domains of the illness but instead provides a simple framework as what the patient is actually doing is considered to represent the proximal "hard outcome" and certainly has the relevance in the management of schizophrenia. Implications of this pragmatic classification system for clinics and research are discussed.

Abstract
The Pattern study was conducted to provide longitudinal observational data for individual patients with persistent symptoms of schizophrenia. Pattern is an international, multicenter, non-interventional, prospective cohort study of schizophrenia outpatients who were not considered to be in recovery. In the longitudinal phase reported herein, patients were assessed over 1 year using different clinical rating scales. Patient management followed routine local clinical practice. Primary outcome was disease state, defined by the Positive and Negative Syndrome Scale (PANSS), Negative Symptom Factor Score (NSFS), Positive Symptom Factor Score (PSFS), and Personal and Social Performance (PSP) Scale. In total, 1344 protocol-compliant patients (70.9% male) were included. Patients showed a high stability in disease state between consecutive study visits. Persistent negative persistent symptoms and symptomatic remission were the most prevalent and stable disease states. Patients in relapse generally transitioned to negative persistent symptoms or to symptomatic remission. PANSS, PSP, and quality of life ratings remained relatively stable. Relapses occurred in 10% of patients; probability of relapse was associated with younger age, extra-pyramidal symptoms, and more antipsychotic medications. Despite treatment, schizophrenia symptoms tend to remain stable over time, without overall improvement. One of the greatest challenges in schizophrenia is attainment of full symptom remission.

Caregiver burden in schizophrenia following paliperidone palmitate long acting injectables treatment: pooled analysis of two double-blind randomized phase three studies. NPJ SCHIZOPHRENIA 2017; 3:23. [PMID: 28751663 PMCID: PMC5532271 DOI: 10.1038/s41537-017-0025-5] [Citation(s) in RCA: 25] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/17/2017] [Revised: 06/22/2017] [Accepted: 06/26/2017] [Indexed: 11/09/2022]
Abstract
The pooled analysis of two double-blind, randomized, multicenter, phase-3 studies evaluated predictors of improvement or worsening of schizophrenia-related caregiver burden following paliperidone palmitate long-acting injectables (1-monthly [PP1M] and 3-monthly [PP3M]) treatment. Caregivers were offered to complete the involvement evaluation questionnaire (involvement evaluation questionnaire; 31-item scale). Total, 1498 caregivers (intent-to-treat open-label analysis set, n = 1497; mean [SD] age: 51.5 [13.02] years, 27 countries) were included: 49% were parents and >50% caregivers spent >32 hours/week in caregiving. Majority of caregivers with considerable burden (n = 1405; mean [SD] baseline involvement evaluation questionnaire scores: 28.4 [15.07]) improved significantly from baseline to end-of-study (n = 756; mean [SD] change from open-label baseline to double-blind endpoint in long-acting injectable scores:−8.9 [14.73]); most improvements were seen in urging followed by worrying, tension, and supervision domains (mean [SD] change from open-label baseline to double-blind endpoint in involvement evaluation questionnaire scores, urging: −3.7 [6.45]; worrying:−2.6 [5.11]; tension:−2.3 [4.84]; supervision: −1.3 [3.69]). Improvements significantly correlated with relapse status, patient age, and age of diagnosis (p < 0.001) while long-acting injectable use at baseline, number, and duration of prior psychiatric hospitalizations (<24 months) had no significant correlation. Caregiver burden was significantly improved for patients on prior oral antipsychotics post-switching to long-acting injectable, with less impact on leisure days and hours spent in caregiving (p < 0.001). Family members of patients with schizophrenia experience considerable caregiver burden. Switching from oral antipsychotic to long-acting injectable can provide meaningful and significant improvement in caregiver burden. Switching from oral to long-acting injectable antipsychotic medication improves overall caregiver burden. The physical, emotional and financial toll of providing care for patients with schizophrenia is often underestimated. Poor adherence to conventional oral antipsychotics is a major cause of symptomatic relapse in patients and of stress for carers. Srihari Gopal and colleagues at Janssen Pharmaceuticals have pooled data from two large studies involving 1498 caregivers across 27 countries. They found that administration of either 1- or 3-monthly long-acting injectable antipsychotics not only eased the burden of daily dosing and patient compliance, but also had a positive impact on the stress conditions of caregivers. Using the Involvement Evaluation Questionnaire to measure caregiver burden, the authors showed that the switch in drug formulation decreased the need to urge patients to self-care and the hours spent caregiving.

Abstract
Introduction Data on the knowledge about antipsychotic medications prescribed in patients with schizophrenia are very limited. Moreover, it remains unclear how patients' knowledge about prescribed antipsychotics affects medication adherence. Methods ighty-one Japanese outpatients with schizophrenia according to the International Classification of Diseases, 10th edition, were included. Patients' knowledge of the primary antipsychotics prescribed to them in terms of therapeutic effects, type, and implicated neurotransmitters was assessed with a multiple-choice questionnaire developed for this study. Medication possession ratios (MPRs) were compared between patients who answered correctly and those who did not in each category. Results The percentages of subjects who answered correctly regarding antipsychotic effects, type, and implicated neurotransmitters were low at 30.9%, 30.9%, and 7.4%, respectively. No differences were found in MPRs between subjects who answered correctly and those who did not. Discussion Our preliminary results indicate that patients lack knowledge about their antipsychotic medications. More concerning, they suggest that knowledge about prescribed antipsychotics may not directly translate into actual medication adherence in patients with schizophrenia.

Abstract
Clinicians and patients differ concerning the goals of treatment. Eighty individuals with schizophrenia were assessed online about which symptoms they consider the most important for treatment, as well as their experience with different interventions. Treatment of affective and neuropsychological problems was judged as more important than treatment of positive symptoms (p < 0.005). While most individuals had experience with Occupational and Sports Therapy, only a minority had received Cognitive-Behavioral Therapy, Family Therapy, and Psychoeducation with family members before. Patients appraised Talk, Psychoanalytic, and Art Therapy as well as Metacognitive Training as the most helpful treatments. Clinicians should carefully take into consideration patients' preferences, as neglect of consumers' views may compromise outcome and adherence to treatment.

Abstract
AIMS Paliperidone palmitate 3-month (PP3M) represents a new long-acting injectable antipsychotic therapeutic option. This review aims: 1) to summarize available data relating to efficacy, safety, tolerability and costs of PP3M; 2) to describe hospitalization rate, occupational status, treatment preference, satisfaction, adherence and caregiver burden of patients with schizophrenia who participate in PP3M clinical trials; 3) to examine ethical implications, pros and cons of PP3M use and 4) to propose study designs to further assess PP3M. METHODS On August 21, 2017, a search on PubMed about PPM3, without any filter restriction, was conducted and all available records were analyzed. Records written in a language other than English were excluded. RESULTS Twenty-two records were included in this review: 6 reviews, 1 report, 4 pharmacokinetic studies, 2 cost-effectiveness analyses, 1 open-label clinical trial, 2 randomized controlled trials (RCTs), 5 studies based on these 2 RCTs and 1 observational study. DISCUSSION According to these last 9 studies, when compared with placebo, PP3M showed a longer time to relapse and good safety and tolerability profiles. Furthermore, when compared with paliperidone palmitate 1 month (PP1M), PP3M treatment showed: 1) non-inferiority in terms of efficacy, safety, tolerability, rate of hospitalization, symptomatic and functional remission, treatment preference and variations of the occupational status; 2) a longer time to relapse after treatment discontinuation and 3) a similar reduction of the caregiver burden. CONCLUSION PP3M is the only 3-monthly long-acting injectable antipsychotic available on the market. This makes it a unique option of treatment, which could be chosen both in early and advanced phases of illness. Nonetheless, longer naturalistic follow-up studies, two-arm head-to-head superiority trials and mirror studies, based on real-world samples of patients, are needed to further assess long-term safety and advantages of this new option of treatment and to define patients' sub-populations that would most beneficiate from it.

Abstract
The dose of antipsychotic required for acute phase treatment of schizophrenia is well established, but there is no consensus on dose required for maintenance phase. Current guidelines do not provide definitive recommendations on the dose of antipsychotics needed in the maintenance treatment of schizophrenia, possibly due to limited research. In this retrospective study, minimum antipsychotic dose prescribed in maintenance treatment of schizophrenia in a real life situation was examined. Schizophrenia patients having Clinical Global Impression - Severity (CGI-S)≤3 for at-least six months during the maintenance phase treatment were included (n=163). The medical records of these patients were reviewed and the antipsychotic dose prescribed for acute and maintenance phase treatment was recorded. The mean antipsychotic dose used during maintenance treatment was approximately 30% lower than the dose used during acute phase. Importantly, about 40% of the subjects maintained well with a dose lesser than the recommended therapeutic range. Earlier age at onset and longer duration of illness were associated with higher antipsychotic dose requirement during the maintenance phase treatment. These findings could have important clinical implications if replicated in systematic prospective studies.

Abstract
Background Assessment of psychosocial functioning in people with schizophrenia is important. The Global Assessment of Functioning (GAF-F) scale represents a widely applied, easy, and quick tool, but its validity and reliability have been debated. The aim was to investigate whether GAF-F scores are associated with other indicators of functioning, severity, and hospitalization. Methods A Danish population-based cohort study of adults (≥18 years) with a recorded GAF-F score at first-time schizophrenia diagnosis during 2004–2011 was performed. The internal validity of GAF-F was evaluated by assessing its association with other baseline measures of functioning and illness severity. Risk of schizophrenia hospitalization within 2 years was evaluated using Cox regression stratified by sex and adjusted for age, year of diagnosis, and inpatient/outpatient status at diagnosis. Results We identified 2,837 cases of schizophrenia with a GAF-F score at first-time diagnosis (73.0% inpatients; 62.6% males). GAF-F was associated with several baseline measures of functioning and illness severity, such as female sex, being in work, and a longer baseline hospitalization. Lower GAF-F scores were associated with higher hospitalization risk among males (reference GAF-F 61–100): GAF-F 51–60: hazard rate ratio (HRR) =1.24 (95% confidence interval [CI] =0.89–1.75); GAF-F 41–50: HRR =1.31 (95% CI =0.97–1.77); GAF-F 31–40: HRR =1.36 (95% CI =1.01–1.82); GAF-F 21–30: HRR =1.50 (95% CI =1.09–2.06); and GAF-F 1–20: HRR =2.30 (95% CI =1.36–3.90), fitting a dose–response relationship (P=0.031). This association was not found in females. Conclusion GAF-F at first-time schizophrenia diagnosis showed good internal validity against other measures of functionality in a Danish hospital setting. Severe impairment (as measured by the GAF-F score) at first-time schizophrenia diagnosis was associated with a higher risk of 2-year hospitalization among males, which may indicate sex differences in the course of disease and treatment response.

Abstract
After 1 year of introduction of olanzapine long-acting injectable (LAI) in India, many psychiatrists believe that it is a very affordable, well-tolerated, and effective second generation long-acting antipsychotic depot compared to not well tolerated but cheap first generation antipsychotic depots and to other second generation depots which are costly. However, reports of its possible adverse events in clinical settings are not yet published. We report what probably might be the first case of postinjection delirium/sedation syndrome (PDSS) in India. Although the occurrence is uncommon, incorrect understanding of this event may hinder the future use of the potentially useful olanzapine LAI. We review the available literature on the proposed diagnostic guidelines, mechanism of this event, precautions, and management of PDSS.

Abstract
Long-acting injectable antipsychotics (LAIs) were developed to make treatment easier, improve adherence, and/or signal the clinician when nonadherence occurs. Second-generation antipsychotic LAIs (SGA-LAIs) combine the advantages of SGA with a long-acting formulation. The purpose of this review is to evaluate the available literature concerning the impact of SGA-LAIs on patient functioning and quality of life (QOL). Although several studies regarding schizophrenia patients' functioning and QOL have been performed, the quantity of available data still varies greatly depending on the SGA-LAI under investigation. After reviewing the literature, it seems that SGA-LAIs are effective in ameliorating patient functioning and/or QOL of patients with schizophrenia, as compared with placebo. However, while methodological design controversy exists regarding the superiority of risperidone LAI versus oral antipsychotics, the significant amount of evidence in recently published research demonstrates the beneficial influence of risperidone LAI on patient functioning and QOL in stable patients and no benefit over oral treatment in unstable patients. However, the status of the research on SGA-LAIs is lacking in several aspects that may help physicians in choosing the correct drug therapy. Meaningful differences have been observed between SGA-LAIs in the onset of their clinical efficacy and in the relationships between symptoms and functioning scores. Moreover, head-to-head studies comparing the effects of SGA-LAIs on classical measures of psychopathology and functioning are available mainly on risperidone LAI, while those comparing olanzapine LAI with other SGA-LAIs are still lacking. Lastly, some data on their use, especially in first-episode or recent-onset schizophrenia and in refractory or treatment-resistant schizophrenia, is available.

Abstract
We describe real-world psychopharmacological treatment in a Japanese, male, closed psychiatric unit where clozapie was still unavailable. Fifty-five persistently-ill patients with schizophrenia (ICD-10), mean ± S.D. age: 57.5 ± 13.0 y.o., duration of illness and admissions: 30.9 ± 15.2 years and 20.7 ± 14.5 years, respectively) treated longitudinally were evaluated. The rule was to treat with a simplest possible psychotropic regimen without polypharmacy. Compared to the baseline, the number and dose of antipsychotics were reduced from 1.9 to 1.1 and 1012 mg/day to 607 mg/day, respectively. The number of total psychotropics was minimized from 4.7 to 2.1, with a simplified once or twice daily dosing. Overall, the CGI-Severity and FACT-Sz (global functioning) improved slightly from 5.8 to 5.5 and 28.7 to 32.6, respectively. Of note, no patients got worse in comparison with the baseline clinical presentation. Forty-four patients were successfully treated with a single antipsychotic; only seven needed two antipsychotics simultaneously while 36 had been treated with antipsychotic polypharmacy at baseline. Benzodiazepines (mostly lorazepam) and antiparkinsonian drugs were prescribed in 28 and only two, respectively. Nineteen needed adjunctive valproate (average blood levels: 99.3 ± 21.8 μg/mL) and nine used lithium (0.61 ± 0.26 mEq/L). Optimization of psychopharmacotherapy is still possible for difficult-to-treat patients and, while augmentation of an antipsychotic with mood stabilizers is frequently needed, antipsychotic polypharmacy should be exceptional.

Abstract
Dopamine partial agonism and functional selectivity have been innovative strategies in the pharmacological treatment of schizophrenia and mood disorders and have shifted the concept of dopamine modulation beyond the established approach of dopamine D2 receptor (D2R) antagonism. Despite the fact that aripiprazole was introduced in therapy more than 12 years ago, many questions are still unresolved regarding the complexity of the effects of this agent on signal transduction and intracellular pathways, in part linked to its pleiotropic receptor profile. The complexity of the mechanism of action has progressively shifted the conceptualization of this agent from partial agonism to functional selectivity. From the induction of early genes to modulation of scaffolding proteins and activation of transcription factors, aripiprazole has been shown to affect multiple cellular pathways and several cortical and subcortical neurotransmitter circuitries. Growing evidence shows that, beyond the consequences of D2R occupancy, aripiprazole has a unique neurobiology among available antipsychotics. The effect of chronic administration of aripiprazole on D2R affinity state and number has been especially highlighted, with relevant translational implications for long-term treatment of psychosis. The hypothesized effects of aripiprazole on cell-protective mechanisms and neurite growth, as well as the differential effects on intracellular pathways [i.e. extracellular signal-regulated kinase (ERK)] compared with full D2R antagonists, suggest further exploration of these targets by novel and future biased ligand compounds. This review aims to recapitulate the main neurobiological effects of aripiprazole and discuss the potential implications for upcoming improvements in schizophrenia therapy based on dopamine modulation beyond D2R antagonism.

Abstract
We describe four elderly male inpatients with chronic schizophrenia successfully withdrawn from long-lasting antipsychotic treatment. Then we review studies in which antipsychotics were discontinued in patients 65 y.o. (or at least 50 on the average) or older using PubMed (last search; August 2014). The average (±S.D.) age, duration of illness and total duration of hospitalization of the patients were 77.0±8.6 y.o., 46.0±26.9 years, and 41.0±27.3 years, respectively. Illness severity as assessed with the Clinical Global Impression (CGI)-Severity was five for three patients and six for the other. After withdrawal from antipsychotic treatment for 28.3±11.4 weeks, none showed appreciable changes in psychopathology, functioning as well as adverse effects and the resultant CGI-Improvement was four for all patients. Compared with those who needed continuous antipsychotic treatment in the same unit (n=51; mean±S.D. age: 56.0±12.1 y.o.), they were significantly older and treated with a fewer number of total psychotropics at baseline (1.50±1.00 versus 4.94±1.93 agents). A literature search failed to find any studies in which antipsychotics were discontinued exclusively in patients with schizophrenia 65 years or older and underscored a clear paucity of data on this important topic. Cessation of chronic antipsychotic treatment could be a viable option at least in some patients with geriatric schizophrenia although more systematic studies are necessary.
