Caracterização clínica e laboratorial de 131 casos (2016 – 2022) de hipercortisolismo ACTH-dependente canino
O objetivo do estudo foi avaliar os aspectos clínicos e laboratoriais de cães com hipercortisolismo dependente do hormônio adrenocorticotrófico (ACTH) em uma série de casos (131). Predominaram fêmeas (63%), idade média de 10 anos, as raças mais frequentes foram Shih-tzu (15,27%), Poodle (14,5%) e Yorkshire (14,5%). Os achados laboratoriais mais comuns foram elevação da atividade de alanina aminotransferase (ALT) (49,56%) e fosfatase alcalina (FA) (75,65%), hipertrigliceridemia (74,34%) e hipercolesterolemia (51,72%). As manifestações clínicas mais frequentes foram poliúria (47,86%), polidipsia (54,70%) e polifagia (47%). As comorbidades mais encontradas foram hepatopatias (70,16%), alterações em vesícula biliar (66,13%) e dermatopatias (11,29%). Concluiu-se que a caracterização dos pacientes foi semelhante a estudos anteriores; porém, com uma frequência menor de manifestações clínicas, sugerindo um diagnóstico em estágios mais precoces
Metabolic correlates of behavioraland affective disturbances in frontal lobepathologies
Abstract.: Objective: Although previous studies have shown that the human frontal cortex is involved in the experience of emotions as well as in social behavior, data regarding the exact anatomical substrates of behavioral and affective deficits in frontal lobe pathologies are still scarce. The aim of this study was to investigate the metabolic correlates of these deficits in a group of non-selected consecutive patients with frontal lobe lesions. Patients and Methods: Clinicometabolic correlations between several emotional and social parameters and metabolic patterns in the frontal cortex and amygdala were investigated in 32 patients with frontal lobe pathologies. The behavioral disturbances were evaluated using the Lhermitte's informant questionnaire. Regional cerebral glucose metabolism was measured with [18F] fluorodeoxyglucose and high-resolution positron emission tomography. Statistical analysis was performed using both single variable correlation and multiple regression analyses. Results: Both single variable and multivariate analyses demonstrate that decreased regional glucose metabolism in the right medial area 10 was associated with apathy. There were also significant negative relationships between metabolism in the right orbitofrontal cortex and stereotypy and indifference to rules. Impulsiveness, personality disturbances and loss of emotional control were associated with decreased metabolism in the left amygdala. Conclusions: In terms of clinicometabolic correlations, the present data support the implication of different functional anatomic systems in frontal lobe-related behavioral and affective disturbances. In particular, they imply that the classically described symptoms of impaired behavioral control may be related to right orbitofrontal cortex hypometabolism whereas impaired regulation of emotions may result from a functional damage of the left amygdal
The Hospital Anxiety and Depression Scale: low sensitivity for depression screening in demented and non-demented hospitalized elderly
Background: We currently use the depression subscale (HADD) of the Hospital Anxiety and Depression Scale (HADS) for depression screening in elderly inpatients. Given recent concerns about the performance of the HADD in this age group, we performed a quality-control study retrospectively comparing HADD with the diagnosis of depression by a psychiatrist. We also studied the effect of dementia on the scale's performance. Methods: HADS produces two 7-item subscales assessing depression or anxiety. The HADD was administered by a neuropsychologist. As "gold standard” we considered the psychiatrist's diagnosis based on the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, criteria. Patients older than 65 years, assessed by both the HADD and the psychiatrist, with a clinical dementia rating (CDR) score lower than 3, were included. The effect of dementia was assessed by forming three groups according to the CDR score (CDR0-0.5, CDR1, and CDR2). Simple and multiple logistic regression models were applied to predict the psychiatrist's depression diagnosis from HADD scores. Areas under the receiver operating characteristics curve (AUC) were plotted and compared by χ2 tests. Results: On both univariate and multiple analyses, HADD predicted depression diagnosis but performed poorly (univariate: p = 0.009, AUC = 0.60 (95% confidence interval (CI) = 0.53-0.66); multiple: p = 0.007, AUC = 0.65 (95% CI = 0.58-0.71)), regardless of cognitive status. Because mood could have changed between the two assessments (they occurred at different points of the hospital stay), the multiple analyses were repeated after limiting time interval at 28, 21, and 14 days. No major improvements were noted. Conclusion: The HADD performed poorly in elderly inpatients regardless of cognitive status. It cannot be recommended in this population for depression screening without further stud

Study approach and field work procedures of the MentDis_ICF65+ project on the prevalence of mental disorders in the older adult European population
Background This study describes the study approach and field procedures of the MentDis_ICF65+ study, which aims to assess the prevalence of mental disorders in older adults. Methods An age-appropriate version of the Composite International Diagnostic Interview (CIDI65+) was developed and tested with regard to its feasibility and psychometric properties in a pre-test and pilot phase. In the cross-sectional survey an age-stratified, random sample of older adults (65–84 years) living in selected catchment areas of five European countries and Israel was recruited. Results N = 3142 participants (mean age 73.7 years, 50.7% female) took part in face-to-face interviews. The mean response rate was 20% and varied significantly between centres, age and gender groups. Sociodemographic differences between the study centres appeared for the place of birth, number of grandchildren, close significants, retirement and self-rated financial situation. The comparison of the MentDis_ICF65+ sample with the catchment area and country population of the study centres revealed significant differences, although most of these were numerically small. Conclusions The study will generate new information on the prevalence of common mental disorders among older adults across Europe using an age-appropriate, standardized diagnostic instrument and a harmonized approach to sampling. Generalizability of the findings and a potentially limited representativeness are discussed
Overview of managed entry agreements : an integrative review towards policy making in Brazil
Resuminho (60 palavras): In order to provide legal and scientific embasement for policy making in Brazil, the aim of this study was to provide a panorama of Managed Entry Agreements around the world. A systematic review was conducted and the information about the agreements were summarized. It was included 25 studies, which described 446 agreements performed in 29 countries. Introduction (100 palavras): Managed Entry Agreements (MEA) are a reality in many countries. They are used as a tool to reduce the impact of uncertainty and the high cost of new drugs by providing access to new technologies under pre-established conditions. In Brazil, the Ministry of Health approved a high-cost technology under performance evaluation, being the first experience in the country. The aim of this study was to conduct a review to identify MEA performed worldwide to provide embasement to inform public health policy making in Brazil, as well as critical considerations surrounding the implementation of performance based agreements. Methods (75 palavras): A review of MEA for health technologies was conducted, using the question ‘What are the health technology managed entry agreements that have being performed around the world?’. The searches were conducted in april 2019, through PUBMED, EMBASE, LILACS and Cochrane Library databases, as well as manual search and gray literature. The selection of studies was performed by two independent reviewers and, in cases of disagreement, solved by a third reviewer. Results (75 palavras): A total of 25 studies were included, describing 446 agreements in 29 countries, being Australia (122), Italy (96), the United States (48) and Scotland (42) more frequent. Financial risk-sharing agreements were the most prevalent (43%). About 95% of the agreements involved medicines - more than half antineoplastic agents. The outcomes assessed and the impact of the agreements were not addressed in most studies, which may be due to the confidentiality character of them. Conclusions (100 palavras): We are likely to see a growth in MEA in the future with the continual launch of new high priced and complex treatments, coupled with increasing demands on available resources. They are an important tool to improve access to innovative and high cost medicines to achieve universal health coverage, although there are critical issues to consider. Besides the embedded confidentiality of most of the agreements, learning from already stablished knowledge, experiences and practices across countries can be a crucial strategy to guide Brazil’s initial experiences in this area
The dimensionality of suicidal ideation and its clinical implications
No consensus has been reached regarding the theoretical dimensions underlying the Scale for Suicide Ideation (SSI) and Beck's Scale for Suicide Ideation (BSI), widely used in research and clinical practice. This undermines the understanding and management of suicidal behavior
The Function of Personality in Suicidal Ideation from the Perspective of the Interpersonal-Psychological Theory of Suicide
The Interpersonal-Psychological Theory of Suicide (IPTS) has been increasingly studied over the last years, responding to the demand for a valid framework addressing suicidality. Yet, only a few studies have explored the function of personality in the IPTS and none with clinical patients. We aimed to contribute to fill this gap in investigating the relationship between personality as conceptualized by the Five-Factor Model, the IPTS constructs, and a dimensional measure of current suicidal ideation. We conducted correlation, multiple linear regression, and path analyses based on a trait-interpersonal framework in a sample of 201 individuals visiting the psychiatric emergency room of a general hospital with current suicidal ideation. Neuroticism (positively) and openness (negatively) predicted perceived burdensomeness, while neuroticism (positively) and extraversion (negatively) predicted thwarted belongingness. Higher conscientiousness and lower extraversion were both predictors of the acquired capability for suicide. However, none of the models involving path analyses with IPTS variables as mediators of the relationship between personality traits and suicidal ideation was adequately adjusted to the data. Thus, it appears that personality plays a significant albeit modest role in suicidality when considered from an IPTS perspective. As personality is frequently assessed in the clinical routine, health professionals should consider it as complementary to detect individuals at risk of or presenting suicidal ideation
