Parkinson's disease has exhibited the most rapid increase in prevalence among neurodegenerative disorders over the past 25 years. With the expanding availability of its surgical interventions and the controversial side effects identified in the literature, it is urgent to develop instruments for discerning subtle changes in patients' biopsychosocial functioning. Therefore, the primary objective of this study was to culturally adapt the Deep Brain Stimulation Impairment Scale (DBS-IS) into Brazilian Portuguese and evaluate its content validity.

Parkinson's disease (PD) is a neurological disorder that primarily affects movement and is often accompanied by depressive symptoms. Subthalamic nucleus (STN) deep brain stimulation (DBS) has emerged as a therapeutic intervention for PD, although its impact on depressive symptoms remains complex. This study investigates the relationship between PD, DBS, and depressive symptoms, focusing on how DBS influences cognitive function and mood among PD patients in Brazil.

Article Synopsis
  • The study analyzed 20 years of data on severe asthma exacerbation (SAE) admissions in adult patients at 40 ICUs in the greater Paris area to understand trends in patient characteristics, management, and outcomes.
  • Admissions for SAE significantly declined over the two decades, dropping from 2.84% of total ICU admissions in 1997-2001 to 1.05% in both 2007-2011 and 2012-2016.
  • Although the use of mechanical ventilation remained low, factors like older age and severe symptoms were linked to higher ICU mortality rates, while overall ICU and hospital mortality decreased over the study period.

Objective: This study aims to identify what existing literature has shown about possible cognitive alterations in unaccompanied refugee children.

Data Sources: The search was performed in the Web of Science, PsycInfo, Scopus, and PubMed databases, including articles published in any year and in any language. The research was submitted to the Prospero protocol (ID: CRD42021257858), and the quality of the included articles was evaluated using the Mixed Methods Appraisal Tool.

Background: Deep brain stimulation (DBS) is considered an alternative treatment for patients with rapidly developing Parkinson's disease (PD). DBS can cause cognitive changes, and it is necessary to perform an executive assessment before and after DBS to better define the prognosis.

Objective: The aim of this study was to analyze the use of the Stroop test for assessment of cognitive functions in patients with PD undergoing DBS.

In active cancers, venous thromboembolism is a poor prognosis factor and one of the main causes of death. Venous thromboembolism is 4 to 7 times more common in patients with active cancer compared with the general population. The risk of thrombosis depends on characteristics related to the patient, cancer, and current treatments.

Unlabelled: Depressive symptoms are associated with a decline of episodic memory, but the relationship with semantic memory remains unclear.

Objective: The aim of the study was to analyze the relationship of depressive symptoms with the semantic memory in a community-based sample of elderly adults. The sample comprised two groups, namely, clinical (with depressive symptoms) and control.

Unlabelled: Given the aging of the world population, it is essential to investigate which methods are most effective for treating the diseases that manifest with age. This study addresses Parkinson's disease (PD), for which Deep Brain Stimulation (DBS) has been increasingly used to treat the disease.

Objective: To investigate Executive Functions (EF) in patients with and without DBS.

Unlabelled: Subjective Well-Being (SWB) is determined by the degree of satisfaction with one's own life and the intensity/frequency with which we experience negative and positive emotions. Current studies indicate that SWB is beneficial for health.

Objective: The aim of this systematic review was to analyze the methodological quality of published articles on SWB in people with Alzheimer's disease (AD).

Introduction: Cognitive impairment in chronic kidney disease (CKD) is commonly associated with neuropsychiatric disorders. As a complex pathology, at all stages of CKD patients need to have a good understanding of the need for drug and nutritional adherence. Cognitive screening is the starting point for detection of cognitive impairments.

Unlabelled: Cognitive functions, such as impulsiveness and executive functions, are often impaired in Parkinson's disease.

Objective: to analyze the relationship between impulsiveness and executive functions (EF) in people with Parkinson's disease (PD).

Methods: a correlation study involving a sample of 50 patients with an established diagnosis of PD aged 40 years or older was conducted using the following instruments: Demographic Questionnaire, Montreal Cognitive Assessment Basic (MOCA-B), Barratt's Impulsiveness Scale (BIS-11) and Frontal Assessment Battery (FAB).

Introduction: There is evidence in the literature that cognitive impairment is more prevalent in individuals with chronic kidney disease (CKD) than in the general population. The Montreal Cognitive Assessment (MoCA) is an instrument with a good application profile for cognitive evaluation of patients with CKD-like impairments. The objective of this study is to perform a systematic review of MoCA use in the context of CKD.

Previous meta-analyses have demonstrated verbal working memory (WM) dysfunction in children and adolescents with attention deficit/hyperactivity disorder (ADHD); however, the findings are inconsistent. The main objective of this meta-analysis was to investigate the performance of children and adolescents with ADHD in the Digit Span Backwards (DSB) subtest from the Wechsler Intelligence Scale for Children or Wechsler Adult Intelligence Scale. We also sought to provide an updated meta-analysis on WM in children and adolescents with ADHD.

Background/aims: Long-term mechanical assist devices are now commonly used in the treatment of severe heart failure to unload the failing ventricle, maintain sufficient end-organ perfusion and improve functional capacity. Depending on the assisted ventricles, 3 categories of long-term assist devices are available: left ventricular assist device (LVAD), biventricular assist device and total artificial heart. Improvements in technology, especially the advent of smaller, durable continuous flow pumps, have led to the use of LVADs in a much broader population of patients in the last 10 years.

Background: Decision-making is a complex, multidimensional cognitive function that requires the choice between two or more options and also the predictive analysis of its consequences. One of the tools most widely used to assess decision-making in neuropsychological research is the Iowa Gambling Task (IGT).

Objective: To conduct a systematic review of articles reporting empirical IGT studies based in Brazil.
