COVID-19 Frequency in Hospitalized Psychiatric Patients: A Systematic Review.

OBJECTIVE: The COVID-19 pandemic affected individuals in different contexts (e.g. long-term care facilities, schools, communities), including psychiatric hospitals. Thus, the objective of this systematic review, duly registered and approved on PROSPERO (CRD42023427835), is to assess the frequency of positive COVID-19 cases among patients hospitalized in psychiatric hospitals. METHODS: A total of 4,922 articles were identified in the database searches, and 17 studies conducted in psychiatric hospitals from different regions of the world were selected. RESULTS: The frequency of positive COVID-19 cases among patients hospitalized in psychiatric hospitals ranged from 1.8% to 98.8%. Out of a total of 19,573 patients hospitalized in psychiatric hospitals, the pooled mean frequency of positive COVID-19 cases was 11.9%. The majority of patients presented COVID-19 symptoms (e.g. cough, fever and others). The COVID-19 diagnosis was primarily conducted through RT-PCR testing in 88.9% of the studies. CONCLUSION: In conclusion, there is discrepancy in the methodology of the studies assessing the frequency of positive COVID-19 cases in psychiatric hospitals. However, this review allowed us to understand how the COVID-19 pandemic has impacted the population hospitalized in psychiatric hospitals.

Effects of empathy training on psychological concerns and empathy in caregivers of older people: A randomized, double-blind, crossover, clinical trial with follow-up.

OBJECTIVES: To investigate the effects of empathy training on psychological concerns and empathy in caregivers of older people. METHODS: A randomized, double-blind, crossover, clinical trial with follow-up was conducted online. Thirty paid and unpaid caregivers of older people from different regions of Brazil participated in an empathy training program. The caregivers answered a sociodemographic questionnaire and measures for the evaluation of empathy (affective and cognitive domains), burden, the impact of providing care as well as depressive symptoms and psychiatric symptoms before and immediately after training. Empathy and its domains were also assessed at three post-intervention follow-ups. RESULTS: Empathy training diminished levels of psychological concerns. Moreover, an increase was found in levels of cognitive empathy 15, 30 and 60 days after the intervention. CONCLUSIONS: Empathy training with a focus on cognitive empathy diminished psychological concerns in caregivers of older people and increased the levels of this ability over time. This intervention can be considered a coping strategy for negative impacts related to providing care. CLINICA LTRIAL REGISTRATION: RBR-8kjtfx3.

Factors associated with happiness among community-dwelling older adults: a systematic review.

OBJECTIVES: To identify factors associated with self-reported happiness among community-dwelling older adults. METHODS: A systematic review of the literature was conducted. Searches were conducted in the PsycInfo, Web of Science, Scopus and Pubmed databases for relevant articles published in English, Spanish or Portuguese using the following search strategy and Boolean operators: (happiness*) AND (elder* OR (old adult*)). No restriction was imposed with regards to year of publication. This review was registered in PROSPERO (CRD42018107302). RESULTS: Forty-six articles met the eligibility criteria and were included in the review. Economic, social and health-related factors were associated with happiness among community-dwelling older adults. The sociodemographic characteristics of older adults, such as the female sex, being married, an older age, a higher level of schooling and having a religion, were also associated with happiness. CONCLUSIONS: The articles included in the present systematic review demonstrate that social, economic and health-related aspects have an association with happiness in community-dwelling older adults.

Development and validation of a brief digital cognitive test based on the paradigm of stimulus equivalence in a sample of older adults.

With the technological advancement and democratization of electronic devices, computerized cognitive tests have been increasingly used in the clinical context to evaluate cognitive performance in individuals. Objective: This study aimed to propose a brief digital cognitive test based on the paradigm of stimulus equivalence and assess its convergent validity by comparing it with traditionally applied tests. Methods: The study was carried out with a non-probabilistic sample of 50 older adults selected from a public call through the communication media, health units, and day centers of a city in the countryside of São Paulo. Participants were assessed by the brief digital cognitive test, Mini-Mental State Examination, Brief Cognitive Screening Battery, and the Five Digit Test. Results: Participants had a mean age of 71.23 years (standard deviation [SD]: ±9.36) and a mean of 7.15 years of schooling (SD: ±5.34). The mean time to answer the test was 5.33 minutes (SD: ±1.92). There were statistically significant correlations between traditional and digital tests in most domains evaluated. In addition, considering the total score of the digital test, the test could discriminate participants with and without cognitive impairment: area under the ROC curve=0.765; 95%CI 0.630-0.901. Conclusion: The brief digital cognitive test, using the stimulus equivalence paradigm, is an easy-to-apply and valid instrument for the investigation of cognitive impairment in older adults.

Conclusão: O teste digital cognitivo breve com o uso do paradigma de equivalência de estímulos é um instrumento de fácil aplicação e válido para a investigação de comprometimento cognitivo em idosos.

Effects of the Acute and Chronic Administration of Cannabidiol on Cognition in Humans and Animals: A Systematic Review.

Introduction: The effects of cannabidiol (CBD) on cognition has been investigated in recent years to determine the therapeutic potential of this cannabinoid for a broad gamut of medical conditions, including neuropsychiatric disorders. The aim of the present study was to perform a systematic review of studies that analyzed the effects of the acute and chronic administration of CBD on cognition in humans and animals both to assess the cognitive safety of CBD and to determine a beneficial potential of CBD on cognition. Methods: The PubMed, Web of Science, PsycINFO, and Scopus databases were searched in December of 2022 for relevant articles using the following combinations of keywords: ("cannabidiol" OR "CBD") AND ("cognition" OR "processing cognitive" OR "memory" OR "language" OR "attention" OR "executive function" OR "social cognition" OR "perceptual motor ability" OR "processing speed"). Results: Fifty-nine articles were included in the present review (36 preclinical and 23 clinical trials). CBD seems not to have any negative effect on cognitive processing in rats. The clinical trials confirmed these findings in humans. One study found that repeated dosing with CBD may improve cognitive in people who use cannabis heavily but not individuals with neuropsychiatric disorders. Considering the context of neuropsychiatric disorders in animal models, CBD seems to reverse the harm caused by the experimental paradigms, such that the performance of these animals becomes similar to that of control animals. Conclusions: The results demonstrate that the chronic and acute administration of CBD seems not to impair cognition in humans without neuropsychiatric disorders. In addition, preclinical studies report promising results regarding the effects of CBD on the cognitive processing of animals. Future double-blind, placebo-controlled, randomized clinical trials with larger, less selective samples, with standardized tests, and using different doses of CBD in outpatients are of particular interest to elucidate the cognitive effects of CBD.

The frequency of psychotic symptoms in types of dementia: a systematic review.

The frequency of psychotic symptoms in older adults is high, mainly in neurocognitive cognitions of the most varied etiologies. Objectives: This study aimed to review the studies that analyze the frequency of the types of delusions, hallucinations, and misidentifications in dementia conditions of different etiologies. Methods: A systematic review was conducted on August 9, 2021, in the PubMed, PsycInfo, Embase, Web of Science, and Scopus databases with the following descriptors: (dementia OR alzheimer disease OR dementia with Lewy bodies OR frontotemporal dementia OR mixed dementia OR vascular dementia OR major neurocognitive disorder OR parkinson disease dementia) AND (psychotic symptoms OR psychosis OR hallucinations OR delusions OR psychopathology OR misidentification) AND (prevalence OR epidemiology). Results: A total of 5,077 articles were found, with a final inclusion of 35. The overall frequency of psychotic symptoms ranged from 34 to 63% in dementia conditions of the most varied etiologies. Alzheimer's disease (AD) presents more delusions and hallucinations and has a higher frequency regarding the presence of misidentifications. On the contrary, Dementia with Lewy bodies (DLB) seems to present more hallucinations, even auditory, when compared to the other dementias, concomitantly with delusions. Vascular and frontotemporal dementia present fewer psychotic symptoms than DLB and AD. Conclusions: We identified a gap in the literature on the description of the psychotic symptoms of dementia, mainly in those of non-AD etiologies. Studies that assess the neuropsychiatric symptoms of dementias deeply might contribute in a more definite manner to the causal diagnosis of dementia.

A frequência de sintomas psicóticos em idosos é alta, principalmente em cognições neurocognitivas das mais variadas etiologias. Objetivos: Revisar os estudos que analisam a frequência dos tipos de delírios, alucinações e erros de identificação em quadros demenciais de diferentes etiologias. Métodos: Foi realizada uma revisão sistemática em 9 de agosto de 2021, nas bases de dados PubMed, PsycInfo, Embase, Web of Science e Scopus, com os seguintes descritores: (demência OR doença de alzheimer OR demência com corpos de Lewy OR demência frontotemporal OR demência mista OR vascular demência OU transtorno neurocognitivo maior OU demência da doença de Parkinson) E (sintomas psicóticos OU psicose OU alucinações OU delírios OU psicopatologia OU identificação errônea) E (prevalência OU epidemiologia). Resultados: Foram encontrados 5.077 artigos, com inclusão final de 35. A frequência geral de sintomas psicóticos foi de 34 a 63% em quadros demenciais das mais variadas etiologias. A doença de Alzheimer (DA) apresenta mais delírios, alucinações e maior frequência quanto à presença de erros de identificação. Por outro lado, a demência com corpos de Lewy (DCL) parece apresentar mais alucinações, inclusive auditivas, quando comparada às demais demências, concomitantemente aos delírios. As demências vascular e frontotemporal apresentam menos sintomas psicóticos do que a DCL e a DA. Conclusões: Identificamos lacuna na literatura quanto à descrição dos sintomas psicóticos das demências, principalmente naquelas de etiologia não DA. Estudos que aprofundem os sintomas neuropsiquiátricos das demências podem contribuir de forma mais definitiva para o diagnóstico causal da demência.

Cannabinoids to Improve Health-Related Quality of Life in Patients with Neurological or Oncological Disease: A Meta-Analysis.

Background: Cannabinoids have been suggested to alleviate frequently experienced symptoms of reduced mental well-being such as anxiety and depression. Mental well-being is an important subdomain of health-related quality of life (HRQoL). Reducing symptoms and maintaining HRQoL are particularly important in malignant primary brain tumor patients, as treatment options are often noncurative and prognosis remains poor. These patients frequently report unprescribed cannabinoid use, presumably for symptom relieve. As studies on brain tumor patients specifically are lacking, we performed a meta-analysis of the current evidence on cannabinoid efficacy on HRQoL and mental well-being in oncological and neurological patients. Methods: We performed a systematic PubMed, PsychINFO, Embase, and Web of Science search according to PRISMA guidelines on August 2 and 3, 2021. We included randomized controlled trials (RCTs) that assessed the effects of tetrahydrocannabinol (THC) or cannabidiol (CBD) on general HRQoL and mental well-being. Pooled effect sizes were calculated using Hedges g. Risk of bias of included studies was assessed using Cochrane's Risk of Bias tool. Results: We included 17 studies: 4 in oncology and 13 in central nervous system (CNS) disease. Meta-analysis showed no effect of cannabinoids on general HRQoL (g=-0.02 confidence interval [95% CI -0.11 to 0.06]; p=0.57) or mental well-being (g=-0.02 [95% CI -0.16 to 0.13]; p=0.81). Conclusions: RCTs in patients with cancer or CNS disease showed no effect of cannabinoids on HRQoL or mental well-being. However, studies were clinically heterogeneous and since many glioma patients currently frequently use cannabinoids, future studies are necessary to evaluate its value in this specific population.

Construction of face databases for tasks to recognize facial expressions of basic emotions: a systematic review.

Recognizing the other's emotions is an important skill for the social context that can be modulated by variables such as gender, age, and race. A number of studies seek to elaborate specific face databases to assess the recognition of basic emotions in different contexts. Objectives: This systematic review sought to gather these studies, describing and comparing the methodologies used in their elaboration. Methods: The databases used to select the articles were the following: PubMed, Web of Science, PsycInfo, and Scopus. The following word crossing was used: "Facial expression database OR Stimulus set AND development OR Validation." Results: A total of 36 articles showed that most of the studies used actors to express the emotions that were elicited from specific situations to generate the most spontaneous emotion possible. The databases were mainly composed of colorful and static stimuli. In addition, most of the studies sought to establish and describe patterns to record the stimuli, such as color of the garments used and background. The psychometric properties of the databases are also described. Conclusions: The data presented in this review point to the methodological heterogeneity among the studies. Nevertheless, we describe their patterns, contributing to the planning of new research studies that seek to create databases for new contexts.

Prevalence of frailty syndrome in Brazil: a systematic review / Prevalência da síndrome da fragilidade no Brasil: uma revisão sistemática

Abstract Background The population is aging rapidly, which leads to an increased prevalence of frailty syndrome. A large number of investigations on the subject have been conducted in Brazil, but no systematic review of prevalence studies involving the Brazilian population has been carried out considering the characteristics of the sample and the evaluation methods used. Objective To develop a systematic review of studies that assess the prevalence of frailty syndrome in Brazil, analyzing the clinical and demographic characteristics of the samples and the methods used for the diagnosis of the syndrome. Method The searches were carried out in the PubMed, SciELO and Web of Science databases using the following keywords: (prevalence or epidemiology) and frailty and Brazil. Results Forty-seven articles met the eligibility criteria and were included in the review. The prevalence of frailty ranged from 3.85% to 74.1%, depending on the assessment instrument used, context, region and population studied. Conclusion The prevalence data are discrepant, and the standardization of screening methods for the frailty syndrome could facilitate the comparison between studies, in order to maximize and create intervention strategies, especially in a country with cultural diversity and regional disparities, such as Brazil

Cultural factors associated with burden in unpaid caregivers of older adults: A systematic review.

The aim of the present systematic review was to investigate cultural factors associated with burden in unpaid caregivers of older adults. Searches were conducted in the Pubmed, Web of Science, PsycInfo, Scopus, Embase, LILACs and SciELO databases for relevant articles published in English, Portuguese and Spanish using the search terms 'Caregiver AND Culture AND (Burnout OR Caregiver Burden) AND Aged'. No restriction was imposed regarding year of publication. A total of 1234 articles were identified, 34 of which were selected for the present review. The following sociodemographic characteristics were associated with burden: being female, married, White caregivers, young and the spouse of the care recipient; having no siblings; having low schooling and low economic status. Cultural factors associated with burden were living with the care recipient, not professing a religion or having little spirituality, familism (i.e. less reciprocity) and an absence of social support. The present findings underscore the importance of developing intervention strategies that consider cultural factors to minimise the negative impacts of care on unpaid caregivers of older adults.

Empathy Training for Caregivers of Older People: A Systematic Review.

OBJECTIVES: To identify empathy training models and the effects on psychological concerns in paid and unpaid caregivers of older people. METHODS: A systematic review was conducted. Searches for relevant articles were performed in the Embase, LILACS, PsycInfo, Pubmed, Scopus and Web of Science databases using the following search strategy: "Empathy AND (Education OR Training OR Intervention) AND Caregiver." No restrictions were imposed regarding language or year of publication. RESULTS: Empathy training for caregivers of older people were performed in six studies, three of which identified a significant increase in empathy levels and consequent reduction in psychological concerns. Empathy training focused on aspects of empathy and/or the caregiver had significant effects on the outcome variables. Moreover, training conducted online, by telephone and/or in person can generate satisfactory results. The other three studies that conducted training with a focus on aspects of dementia and/or old age did not present any effect on the outcome variables. CONCLUSIONS: Empathy training for caregivers of older people can increase levels of this ability, especially in the cognitive domain, as well as diminish psychological concerns caused by the negative impact of providing care. CLINICAL IMPLICATIONS: Empathy training directed at empathic abilities and/or aspects of providing care can be effective at increasing levels of this ability. Moreover, training in different care contexts can minimize the negative impacts of providing care.

Psychological Concerns Associated with Empathy in Paid and Unpaid Caregivers of Older People: A Systematic Review.

OBJECTIVES: Identify associations between psychological concerns and empathy (affective and cognitive domains) in paid and unpaid caregivers of older people. METHODS: A systematic review of the literature was conducted. Searches were performed in the Pubmed, Web of Science, PsycINFO, Scopus and Embase databases using the search terms "Empathy," "Caregiver," "Depression," "Burnout," Anxiety", Caregiver Burden" and "Psychological Stresses" and the Boolean operators "AND" and "OR." No restrictions were imposed regarding language or year of publication. This review was registered in PROSPERO (CRD42021267276). RESULTS: Twelve articles met the inclusion criteria and were included in the present review. Most studies involved the participation of unpaid caregivers. Higher levels of empathy were associated with greater psychological concerns. Regarding affective empathy, direct associations were found with depressive symptoms, anxiety and stress. In contrast, high levels of cognitive empathy were associated with fewer depressive symptoms as well as less stress and burnout syndrome. CONCLUSIONS: An association was found between greater affective empathy and psychological impairment in caregivers of older people. Higher levels of cognitive empathy can help minimize psychological concerns. CLINICAL IMPLICATIONS: Working on empathic ability among caregivers of older people in different environments can contribute positively to the emotional impact of caregiving. Moreover, empathetic cognitive training among caregivers can serve as a strategy to minimize the negative consequences of the impact of caregiving.

Association between falls and cognitive performance among community-dwelling older people: a cross-sectional study

ABSTRACT BACKGROUND: Falls among older people have a negative impact on health and therefore constitute a public health problem. Cognitive decline can also accompany the aging process, and both conditions lead to significant increases in morbidity and mortality in this population. Objective: To analyze the cognitive performance of older people, classified as non-fallers, sporadic fallers and recurrent fallers, and investigate the relationship between falls and cognition. DESIGN AND SETTING: Cross-sectional study conducted in the interior of the state of São Paulo, Brazil. METHODS: Evaluations on 230 older people were conducted. They were divided into three groups: non-fallers, sporadic fallers (one fall) and recurrent fallers (two or more falls). The Mini-Mental State Examination, Consortium to Establish a Registry for Alzheimer's Disease (CERAD), Brief Cognitive Screening Battery (BCSB), Cambridge Examination for Mental Disorders of the Elderly (CAMDEX) similarities subtest and digit span test were applied. RESULTS: In multinomial logistic regression, being a recurrent faller was significantly associated with lower scores in the CERAD word list (odds ratio, OR = 0.92; 95% confidence interval, CI, 0.86-0.98; P = 0.01), in CERAD constructive praxis (OR = 0.88; 95% CI, 0.79-0.98; P = 0.02), in BCSB figure list memory (OR = 0.94; 95% CI, 0.89-0.99; P = 0.02) and in verbal fluency (OR = 0.89; 95% CI, 0.81-0.97; P = 0.01). Recurrent fallers also had lower scores in these same tests, compared with sporadic fallers. CONCLUSION: Cognitive impairment, especially in the domains of memory and executive functioning, can influence occurrences of recurrent falls.

RESULTS: In multinomial logistic regression, being a recurrent faller was significantly associated with lower scores in the CERAD word list (odds ratio, OR = 0.92; 95% confidence interval, CI, 0.86-0.98; P = 0.01), in CERAD constructive praxis (OR = 0.88; 95% CI, 0.79-0.98; P = 0.02), in BCSB figure list memory (OR = 0.94; 95% CI, 0.89-0.99; P = 0.02) and in verbal fluency (OR = 0.89; 95% CI, 0.81-0.97; P = 0.01). Recurrent fallers also had lower scores in these same tests, compared with sporadic fallers. CONCLUSION: Cognitive impairment, especially in the domains of memory and executive functioning, can influence occurrences of recurrent falls.

What factors are associated with affective and cognitive empathy in informal and formal caregivers of older people?

OBJECTIVE: To analyse factors associated with affective and cognitive empathy in informal and formal caregivers of older people. METHODS: A cross-sectional study was conducted with 111 formal and informal caregivers divided into three groups (lower, intermediate and higher empathy) based on the Multidimensional Interpersonal Reactivity Index score (total, affective and cognitive empathy). A sociodemographic questionnaire, the Zarit Burden Inventory, Patient Health Questionnaire-9 and Functional Assessment Questionnaire were applied. RESULTS: The participants were predominantly women (91%), and median [IQR] age was 46 [33-57] years. In the multinomial regression analysis being an informal caregiver, being older and having depressive symptoms were associated with higher levels of empathy (total score and the affective domain). No associations were found for the cognitive domain. CONCLUSIONS: A high level of empathy, especially affective empathy, was associated with depressive symptoms, older age and being an informal caregiver. Family relationships and the lack of training among informal caregivers should be explored.

Reliability of the Theory of Mind Task Battery (ToM TB) to assess social cognition in post-stroke patients.

Theory of mind is the ability to understand, and infer thoughts or mental states to others. This is a central domain of social cognition that can be impaired after brain injury, resulting in changes in social skills and implications for rehabilitation.The aim of this investigation was to analyze the reliability of the Theory of Mind Task Battery (ToM TB) in post-stroke patients.This is a cross-sectional prospective study with psychometric characteristics, involving 38 patients diagnosed with ischemic or hemorrhagic stroke assessed by three examiners using the ToM TB scale, translated and adapted to Brazilian Portuguese. Satisfactory levels of interexaminer agreement were found for almost all categories of the ToM TB: Kappa ranged from 0.036 to 1.00, total score (ICC) from 0.958 to 0.999 and a Cronbach's alpha of 0.658 was obtained with the complete instrument.The Brazilian version of the ToM TB in post-stroke patients is a reliable instrument that can be used to assess the theory of mind, prognosis and rehabilitation of post-stroke patients.

Recognition of Facial Expressions of Emotion and Depressive Symptoms among Caregivers with Different Levels of Empathy.

OBJECTIVES: To assess differences in the recognition of facial expressions of emotion among caregivers of older people with different levels of empathy. METHODS: A cross-sectional study was conducted with 158 caregivers of older adults who provided care in family residences or nursing homes. The caregivers were divided into three groups based on the score of the multidimensional Interpersonal Reactivity Index: "lower empathy", "intermediate empathy", and "higher empathy". Data collection involved the administration of a sociodemographic questionnaire, the Emotion Recognition Test, and the Patient Health Questionnaire. RESULTS: No significant differences were found among the groups in terms of sociodemographic variables. Regarding clinical characteristics, the "higher empathy" group had more depressive symptoms than the other groups (p = .001). Moreover, the "higher empathy" group exhibited greater accuracy at recognizing the expression of sadness than the "lower empathy" group (p = .033). The recognition of sadness remained significant in the analysis of variance adjusted for depressive symptoms (p < .05). CONCLUSIONS: Caregivers with higher levels of empathy showed greater accuracy at recognizing sadness emotion compared to caregivers with lower levels of empathy. Additionally, caregivers with greater empathy have more depressive symptoms. CLINICAL IMPLICATIONS: The recognition of facial expressions of sadness may give caregivers a skill to infer possible needs in older care recipients. However, a higher level of empathy may exert a negative psychological impact on caregivers of older people, which could have repercussions regarding the quality of care provided.
