RESUMEN

Effective management of schizophrenia (SZ) requires long-term treatment with antipsychotics (APs) to prevent clinical relapse, attain remission and improve patients' personal and social functioning, and quality of life. Although APs remain the cornerstone treatment for patients with SZ, despite their potential benefits, long-acting injectable APs (LAI-APs) remain underused, most notably in women with SZ. The efficacy and tolerability of APs differ significantly between men and women, and some of these differences are more noticeable depending on the patient's age and the stage of the disorder. Although sex differences may influence treatment outcomes in SZ, their pertinence has been insufficiently addressed, especially regarding the use of LAI-APs. Some biological and social experiences, such as pregnancy, lactation, contraception and menopause, are specific to women, but these remain under-researched issues. Implications of this disorder in parenting are also of special pertinence regarding women; therefore, taking sex differences into account when treating SZ patients is now recommended, and improving personalized approaches has been proposed as a priority in the management of psychosis. In this narrative, critical review, we address some aspects specific to sex and their implications for the clinical management of women with SZ, with a special focus on the potential role of LAI-AP treatments.


• Schizophrenia is a chronic mental illness, and patients often need to take antipsychotic medications in the long-run in order to stay well, avoid re-occurrence of symptoms and improve their everyday functioning and quality of life. • Antipsychotics are available in both pill and injection form. The latter is known as long-acting injectable antipsychotics (LAI-APs) and can be administered from weekly to twice a year. • Despite their effectiveness and practicality due to less frequent administration, LAI-APs remain largely underused, especially in women with schizophrenia. • The efficacy and tolerability of antipsychotics can be very different between men and women, and some of these differences may be more pronounced depending on the patient's age and the phase of the illness. • Notably, physical and social aspects such as pregnancy, lactation, contraception, parenting and menopause and their effects on the treatment with antipsychotics and particularly LAI-APs in women with schizophrenia are under-studied. • Nevertheless, we have now become more aware of the importance of these sex differences, and it is recommended to take them routinely into consideration when treating patients with schizophrenia in clinical practice. • In this article, we discuss how factors specific to sex can influence the treatment of women with schizophrenia and focus on the potential role of LAI-AP medications.

RESUMEN

Negative symptoms in the context of psychosis are still poorly understood and diagnosed, which impairs the treatment efficacy of current therapies and patient's integration in society. In this study, we aimed to test hypothesis-based and exploratory associations of negative symptom domains, as defined by the Brief Negative Symptom Scale (BNSS), with hormonal and hematological variables, and, complementarily, with standard psychological/cognitive and psychopathological measures. Fifty-one male patients diagnosed with a psychotic disorder underwent a structured interview and blood collection. Standard Spearmen bivariate correlations were used for data analysis. We obtained evidence of hypothesis-based associations between specific negative symptoms and oxytocin, thyroid stimulating hormone levels and neutrophil-to-lymphocyte ratio; as well as novel and hypothesis-free associations with erythrocyte and lymphocyte count, mean corpuscular volume and red cell distribution width. Complementarily, we also obtained some validation of previous associations of negative symptoms with illness resolution, cognitive symptom severity and social performance, and a novel association with anger contagion. We hope our results can generate new hypotheses in psychosis research. Our work suggests further avenues in research on erythrocytic, inflammatory, thyroid and oxytocin-related markers and abnormalities in psychosis, especially in regards to specific negative symptoms, towards more precise and comprehensive etiological, diagnostic and therapeutic models.

RESUMEN

In its early stage, the COVID-19 pandemic and the subsequent public health measures brought several challenges to people in general, with adolescents being one of the most affected groups. To assess the psychological reactions of Portuguese adolescents in that early phase of the COVID-19 pandemic, we conducted an online survey that was filled by a sample of 340 (67.6% female and 32.4% male) middle adolescents (aged 16 and 17 years). Using the Impact Event Scale-Revised and the Depression, Anxiety, and Stress Scale, we found that most participants reported a normal score for depression, anxiety, and stress. However, 47.1% reported some level of pandemic-related traumatic distress, and 25.6% reported high severity values. The girls' levels of depression, anxiety, stress, and traumatic distress were significantly higher than those of the boys. Regression models showed that gender, number of symptoms experienced in the past days, self-reported health status, and concern with family were significant predictors of these mental health indicators. Our findings underscore the need for future research on the long-term traumatic psychological impact of the COVID-19 pandemic in adolescents, and on the gender differences in this group. This will allow the development of strategies to identify and address at-risk adolescents, since the promotion of mental health and the prevention of pathology are imperative for the health of current and future generations.

RESUMEN

Maintenance of response in schizophrenia is largely dependent on compliance with antipsychotic treatment. When people with schizophrenia are responsible for their own treatment, partial or non-adherence is common and usually results in relapse. Assured compliance with antipsychotic treatment is possible when long-acting injectable antipsychotics are given by healthcare staff, but some patients may not consent to treatment for a variety of reasons. An alternative to long-acting injections is the use of supervised oral administration of long-acting antipsychotics. This method assures compliance with prescribed regimens without the need for injections. To be suitable for once-weekly administration as an oral formulation, an antipsychotic needs to have a sufficiently long duration of action and to be well tolerated in high doses. There is evidence that weekly oral administration of either pimozide or penfluridol is effective and well tolerated in the treatment of schizophrenia. Other drugs potentially suitable for once-weekly oral administration include aripiprazole, brexpiprazole and cariprazine.

RESUMEN

The COVID-19 pandemic has become one of the main international concerns regarding its impact on mental health. The present study aims to investigate the prevalence of depression, anxiety, and stress symptoms, and behavioral aspects amidst the COVID-19 pandemic in a Brazilian population. An online survey was administered from May 22 to June 5, 2020 using a questionnaire comprising of sociodemographic information, the Depression, Anxiety, and Stress Scale (DASS-21), and the Coping Strategies Inventory. Participants comprised 3,000 people from Brazil's 26 states and the Federal District, with an average age of 39.8 years, women (83%), married (50.6%), graduates (70.1%) and employees (46.7%). Some contracted the virus (6.4%) and had dead friends or relatives (22.7%). There was more consumption of drugs, tobacco, medication, and food (40.8%). Almost half of participants expressed symptoms of depression (46.4%), anxiety (39.7%), and stress (42.2%). These were higher in women, people without children, students, patients with chronic diseases, and people who had contact with others diagnosed with COVID-19. The existence of a group more vulnerable to situations with a high stress burden requires greater attention regarding mental health during and after the pandemic. That said, it should be emphasized that these findings are preliminary and portray a moment still being faced by many people amid the pandemic and quarantine measures. Therefore, we understand that the magnitude of the impacts on mental health will only be more specific with continuous studies after total relaxation of the quarantine.

RESUMEN

Like previous pandemics, the coronavirus disease 2019 (COVID-19) has direct and indirect effects, including in mental health. To evaluate the immediate psychological impact of COVID-19, we conducted an online survey in Portugal (24-27 March 2020), using the Impact of Event Scale-Revised (IES-R) and the Depression, Anxiety and Stress Scale (DASS-21). From the 10,529 participants (M = 31.33; SD = 9.73), 83.4% were women, had a mean age of 31.2 years, and 70.9% were active workers. Depression, anxiety, and stress were rated as moderate to severe in 11.7%, 16.9%, and 5.6% of the sample, respectively. Moreover, 49.2% of participants reported a moderate or severe psychological impact of the outbreak. Women, the unemployed, those with lower education, living in rural areas, and with flu-like symptoms or chronic disorders were risk factors. Further research is needed to identify vulnerable groups to better inform and adapt mental health policies and interventions.

RESUMEN

Instruments designed to evaluate the necessity of compulsory psychiatric treatment (CPT) are scarce to non-existent. We developed a 25-item Checklist (scoring 0 to 50) with four clusters (Legal, Danger, Historic and Cognitive), based on variables identified as relevant to compulsory treatment. The Compulsory Treatment Checklist (CTC) was filled with information on case (n=324) and control (n=251) subjects, evaluated under the Portuguese Mental Health Act (Law 36/98), in three hospitals. For internal validation, we used Confirmatory Factor Analysis (CFA), testing unidimensional and bifactor models. Multilevel logistic regression model (MLL) was used to predict the odds ratio (OR) for compulsory treatment based on the total scale score. Receiver Operating Characteristic analysis (ROC) was performed to predict compulsory treatment. CFA revealed the best fit indexes for the bifactor model, with all items loading on one General factor and the residual loading in the a priori predicted four specific factors. Reliability indexes were high for the General factor (88.4%), and low for specific factors (<5%), which demonstrate that CTC should not be performed in the subscales to access compulsory treatment. MLL reveals that for each item scored in the scale, it increases the OR by 1.26 for compulsory treatment (95%CI 1.21-1.31, p<0.001). Based on the total score, accuracy was 90%, and the best cut-off point of 23.5 detects compulsory treatment with a sensitivity of 75% and specificity of 93.6%. The CTC presents robust internal structure with a strong unidimensional characteristic, and a cut-off point for compulsory treatment of 23.5. The improved 20-item version of the CTC could represent an important instrument to improve clinical decision regarding CPT, and ultimately to improve mental health care of patients with severe psychiatric disorders.

RESUMEN

Despite their widespread use, long-acting injectable (LAI) antipsychotics (APs) are often regarded with some negativity because of the assumption of punishment, control and insufficient evolution towards psychosocial development of patients. However, LAI APs have proved effective in schizophrenia and other severe psychotic disorders because they assure stable blood levels, leading to a reduction of the risk of relapse. Therapeutic opportunities have also arisen after introduction of newer, second-generation LAI APs in recent years. Newer LAI APs are more readily dosed optimally, may be better tolerated and are better suited to integrated rehabilitation programmes. This review outlines the older and newer LAI APs available for the treatment of schizophrenia, with considerations of past and present pharmacological and therapeutic issues. Traditional, evidence-based approaches to systematic reviews and randomized clinical trials are of limited utility in this area so this paper's blending of experimental trials with observational research is particularly appropriate and effective.

RESUMEN

OBJECTIVE: Patients with schizophrenia (SZ) often present sleep complaints, and patients with sleep disturbances are at a greater risk for symptom worsening after antipsychotic discontinuation. Long-term adherence to antipsychotic treatment remains a challenge for clinicians, and the relationship between quality of sleep and treatment adherence in SZ outpatients has been poorly studied. METHODS: In this cross-sectional, non-interventional study, 811 adult outpatients with a diagnosis of SZ were divided into two groups according to the presence (or absence) of sleep disturbances, and assessed using measures of symptom severity, quality and patterns of sleep, adherence/compliance to treatment, and family support degree. RESULTS: Patients with sleep disturbances were significantly more symptomatic (p < 0.0001), and scored significantly higher on the Pittsburgh Sleep Quality Index (PSQI) as compared with patients without sleep disturbances (p < 0.0001). More compliant patients showed less sleep disturbances (p < 0.0001); moreover, patients with worse compliance to pharmacological treatment showed significantly higher scores on the PSQI (p < 0.0001). Regarding family support degree, patients with sleep disorders presented a lower family support (p = 0.0236), and patients with worse treatment adherence had worse family support (p < 0.0001). CONCLUSIONS: Our findings show that SZ outpatients reporting sleep disturbances show greater symptom severity, and worse adherence/compliance to treatment, as well as a lower family support.

RESUMEN

Patients with schizophrenia often present sleep complaints, but its relationship with general satisfaction with life (SWL) and burden for caregivers has been understudied. We aimed to assess the differences in SWL between patients with and without self-reported sleep disturbances and that of their caregivers. In a noninterventional study, 811 schizophrenia adult outpatients were screened for their subjective perception of having (or not) sleep disturbances and evaluated with the Brief Psychiatric Rating Scale (BPRS) and the Pittsburgh Sleep Quality Index (PSQI). Patients self-reporting sleep disturbances were significantly more symptomatic (P < 0.001), presented significantly worse family support (P = 0.0236), and self-reported worse SWL in all domains. Caregivers of patients with schizophrenia self-reporting sleep disturbances also reported worse SWL in all domains, as compared to caregivers of patients without subjective sleep disturbances. Patient and caregivers' SWL was significantly correlated to patients' quality of sleep (P < 0.0001 for all domains). Patient' and caregivers' SWL was negatively affected by patients' poor quality of sleep. We found that patients self-reporting sleep disturbances showed greater symptom severity, worse quality of sleep, worse SWL, and less caregiver support. SWL was also worse for caregivers of patients with schizophrenia reporting sleep disturbances.

RESUMEN

PURPOSE: Deficits in social functioning are a core feature of schizophrenia and are influenced by both symptomatic and neurocognitive variables. In the present study we aimed to determine the reliability and validity of the Portuguese version of the Personal and Social Performance (PSP) scale, and possible correlations with measures of cognitive functioning. METHODS: One-hundred and four community and inpatients with schizophrenia were assessed using measures of social functioning and symptom severity alongside measures of executive function, processing speed, and verbal memory. RESULTS: Convergent validity with the GAF in the four domains of the PSP varied from 0.357 to 0.899. Reliability was found to be satisfactory, with a Cronbach's alpha coefficient of 0.789. Inter-rater reliability in the four domains of the PSP varied from 0.430 to 0.954. Low-functioning patients (PSP < 70) were older, had longer duration of illness, were more symptomatic and had worse cognitive performances, as compared with high-functioning patients (PSP ≥ 70). In a regression model, deficits in social functioning were strongly predicted both by symptomatic and neurocognitive variables; these together accounted for up to 62% of the variance. CONCLUSIONS: The present study supports the reliability and validity of the Portuguese language version of the PSP and further supports the original measure. The co-administration of brief cognitive assessments with measures of functioning may lead to more focused interventions, possibly improving outcomes in this group.
