Cross-national Psychometric Evaluation of the Jefferson Scale of Empathy-Medical Student Version.

This study aimed to examine the factorial structure of the Jefferson Scale of Empathy-Medical student version (JSE-S) and assess items' discriminatory ability at higher and lower empathy levels in medical student populations from different countries and languages. JSE-S datasets were retrieved from previous studies of 4113 first- and/or second-year medical students from Switzerland, Portugal, Italy, Brazil, France, Spain, New Zealand, UK, Ireland, Mexico, and Peru. Parallel principal component analyses and item response theory were applied.

Psychometric properties of the positive mental health questionnaire: short form (PMHQ-SF18) in young adults.

Introduction: Positive Mental Health (PMH) plays a pivotal role in the promoting of mental health. Assessing this phenomenon is essential for early recognition and intervention in mental health. To date, only one tool was validated with 39 items to assess PMH among Portuguese young adults.

Objective structured assessment ultrasound skill scale for hyomental distance competence - psychometric study.

Background: Ultrasound assessment of the airway recently integrates the point-of-care approach to patient evaluation since ultrasound measurements can predict a difficult laryngoscopy and tracheal intubation. Because ultrasonography is performer-dependent, a proper training and assessment tool is needed to increase diagnostic accuracy. An objective, structured assessment ultrasound skill (OSAUS) scale was recently developed to guide training and assess competence.

The relation between lifestyles and positive mental health in Portuguese higher education students.

Healthy lifestyles are commonly associated with improved physical and mental health. Sleep patterns, nutrition, physical exercise, consumption of psychoactive substances, among others, can strongly influence positive mental health. The aims are: characterize lifestyles based on positive mental health clusters, considering the cross-sectional cohort sample of higher education students, and analyse the lifestyles associated with positive mental health.

Ultrasound-Guided Selective Bronchial Intubation: A Feasibility Study in Pediatric Animal Model.

Objective: Selective one-lung ventilation used to optimize neonatal and pediatric surgical conditions is always a demanding task for anesthesiologists, especially during minimally invasive thoracoscopic surgery. This study aims to introduce an ultrasound-guided bronchial intubation and exclusion technique in a pediatric animal model.

Methods: Seven rabbits were anesthetized and airway ultrasound acquisitions were done.

Lipocalin-2 does not influence EAE clinical score but it increases inflammation in central nervous system.

The contribution of lipocalin-2 (LCN2) to multiple sclerosis (MS) is controversial. Herein, we induced experimental autoimmune encephalomyelitis (EAE) in LCN2-null and wild-type (Wt) mice. While we did not find differences between genotypes regarding clinical score, LCN2-null EAE mice presented decreased expression of interferon gamma and diminished demyelination in the cerebellum.

A new scale informed by the Reciprocal-Engagement Model for quality evaluation of genetic counselling by patients: Development and initial validation.

Monitoring the quality of genetic counselling is essential to ensure appropriate provision. This study describes the development and initial psychometric validation of a novel scale for genetic counselling quality evaluation by patients. A deductive approach was taken to formulate scale items.

Prediction and cost-effectiveness comparison of amblyopia screening methods at ages 3-4 years.

Purpose: Compare the performance of different amblyopia screening tests.

Methods: Based on exploratory factor analyses (EFA) of different screening tests performed in 3295 children, we created models of screening strategies in a matrix with: uncorrected visual acuity (UCVA), Plusoptix measurements (PO), Randot Stereo-test (SR), and Cover-Test (CT). Receiver Operating Characteristic (ROC) curves and confusion matrix were used to compare performance of different model's algorithm to predict new diagnosis of amblyopia.

European Portuguese Version of the User Satisfaction Evaluation Questionnaire (USEQ): Transcultural Adaptation and Validation Study.

Background: Wearable activity trackers have the potential to encourage users to adopt healthier lifestyles by tracking daily health information. However, usability is a critical factor in technology adoption. Older adults may be more resistant to accepting novel technologies.

Useful Ultrasonographic Parameters to Predict Difficult Laryngoscopy and Difficult Tracheal Intubation-A Systematic Review and Meta-Analysis.

Unexpected difficult airway management can cause significant morbidity and mortality in patients admitted for elective procedures. Ultrasonography is a promising tool for perioperative airway assessment, nevertheless it is still unclear which sonographic parameters are useful predictors of difficult laryngoscopy and tracheal intubation. To determine the ultrasonographic predictors of a difficult airway that could be applied for routine practice, a systematic review and meta-analysis was conducted.

Amblyopia screening effectiveness at 3-4 years old: a cohort study.

Objective: To study the effectiveness of amblyopia screening at ages 3-4.

Methods And Analysis: From a population with no previous screening, a cohort of 2300 children with 3-4 years old attending school (91% of children this age attend school in Portugal), were submitted to a complete ophthalmological evaluation. Amblyopia was diagnosed, treated and followed.

25-OH Vitamin D Levels and Cognitive Performance: Longitudinal Assessment in a Healthy Aging Cohort.

: Declining serum levels of 25-hydroxyvitamin D [25(OH)D, a biomarker of vitamin D status] with aging is a well-recognized phenomenon. However, scarce information is available on the relation between 25(OH)D levels and cognitive performance over time in older individuals. Our purpose was to evaluate, longitudinally, the association of 25(OH)D with cognitive function in a healthy older adults' cohort.

Assessment of Undergraduates' Real-World Outcomes of Critical Thinking in Everyday Situations.

Critical thinking is a kind of "good" thinking that integrates a set of cognitive skills and dispositions to use those skills with knowledge to increase the chances of success in academic settings, job market, and daily life. The impact of critical thinking on life events, in face of everyday decisions and challenges, is still unclear, and further research is needed. In this exploratory study, a sample of 230 first-year students of a Bachelor's Degree or a Master's Degree in Portugal completed an experimental Portuguese version of the , a self-report inventory measuring everyday negative life events that are mediated by a lack of critical thinking.

Placebo prescription and empathy of the physician: A cross-sectional study.

Background: Empathy in the patient-physician relationship is a major component in an effective placebo treatment, as in every medical treatment. Understanding the role of empathy of the physician in the placebo effect may help dissect some of the context variables responsible for the effectiveness of the placebo.

Objectives: To determine the frequency of placebo prescription, doctors' beliefs, motivation, and attitudes to placebos in general practice in northern Portugal and to test the association between placebo prescription and physician empathy.

Adult Body Height Is a Good Predictor of Different Dimensions of Cognitive Function in Aged Individuals: A Cross-Sectional Study.

Adult height, weight, and adiposity measures have been suggested by some studies to be predictors of depression, cognitive impairment, and dementia. However, the presence of confounding factors and the lack of a thorough neuropsychological evaluation in many of these studies have precluded a definitive conclusion about the influence of anthropometric measures in cognition and depression. In this study we aimed to assess the value of height, weight, and abdominal perimeter to predict cognitive impairment and depressive symptoms in aged individuals.

The Advantages of Structural Equation Modeling to Address the Complexity of Spatial Reference Learning.

Background: Cognitive performance is a complex process influenced by multiple factors. Cognitive assessment in experimental animals is often based on longitudinal datasets analyzed using uni- and multi-variate analyses, that do not account for the temporal dimension of cognitive performance and also do not adequately quantify the relative contribution of individual factors onto the overall behavioral outcome. To circumvent these limitations, we applied an Autoregressive Latent Trajectory (ALT) to analyze the Morris water maze (MWM) test in a complex experimental design involving four factors: stress, age, sex, and genotype.

Discriminant power of socio-demographic characteristics and mood in distinguishing cognitive performance clusters in older individuals: a cross-sectional analysis.

Objectives: Identification of predictors of cognitive trajectories has been a matter of concern on aging research. For this reason, it is of relevance to infer cognitive profiles based on rapid screening variables in order to determine which individuals will be more predisposed to cognitive decline.

Method: In this work, a linear discriminant analysis (LDA) was conducted with socio-demographic variables and mood status as predictors of cognitive profiles, computed in a previous sample, based on different cognitive dimensions.

The Use of Canonical Correlation Analysis to Assess the Relationship Between Executive Functioning and Verbal Memory in Older Adults.

Executive functioning (EF), which is considered to govern complex cognition, and verbal memory (VM) are constructs assumed to be related. However, it is not known the magnitude of the association between EF and VM, and how sociodemographic and psychological factors may affect this relationship, including in normal aging. In this study, we assessed different EF and VM parameters, via a battery of neurocognitive/psychological tests, and performed a Canonical Correlation Analysis (CCA) to explore the connection between these constructs, in a sample of middle-aged and older healthy individuals without cognitive impairment ( = 563, 50+ years of age).

Exploring the factor structure of neurocognitive measures in older individuals.

Here we focus on factor analysis from a best practices point of view, by investigating the factor structure of neuropsychological tests and using the results obtained to illustrate on choosing a reasonable solution. The sample (n=1051 individuals) was randomly divided into two groups: one for exploratory factor analysis (EFA) and principal component analysis (PCA), to investigate the number of factors underlying the neurocognitive variables; the second to test the "best fit" model via confirmatory factor analysis (CFA). For the exploratory step, three extraction (maximum likelihood, principal axis factoring and principal components) and two rotation (orthogonal and oblique) methods were used.

The role of sex and sex-related hormones in cognition, mood and well-being in older men and women.

Alterations in hormone levels during aging impact on cognition and mood. Serum concentration levels of testosterone (TT), estradiol (E2), follicle-stimulating hormone (FSH), luteinizing hormone (LH), dehydroepiandrosterone sulfate (DHEAS) and prolactin (PRL) were assessed in 120 community-dwellers (51+ years of age, males and females), in a cross-sectional approach. Performance clusters based on executive functioning (GENEXEC), memory (MEM), mood and well-being were obtained.

Day and night: diurnal phase influences the response to chronic mild stress.

Chronic mild stress (CMS) protocols are widely used to create animal models of depression. Despite this, the inconsistencies in the reported effects may be indicative of crucial differences in methodology. Here, we considered the time of the diurnal cycle in which stressors are applied as a possible relevant temporal variable underlying the association between stress and behavior.

Clinical, physical and lifestyle variables and relationship with cognition and mood in aging: a cross-sectional analysis of distinct educational groups.

It is relevant to unravel the factors that may mediate the cognitive decline observed during aging. Previous reports indicate that education has a positive influence on cognitive performance, while age, female gender and, especially, depressed mood were associated with poorer performances across multiple cognitive dimensions (memory and general executive function). Herein, the present study aimed to characterize the cognitive performance of community-dwelling individuals within distinct educational groups categorized by the number of completed formal school years: "less than 4," "4, completed primary education," and "more than 4.

The Use of Multiple Correspondence Analysis to Explore Associations between Categories of Qualitative Variables in Healthy Ageing.

The main focus of this study was to illustrate the applicability of multiple correspondence analysis (MCA) in detecting and representing underlying structures in large datasets used to investigate cognitive ageing. Principal component analysis (PCA) was used to obtain main cognitive dimensions, and MCA was used to detect and explore relationships between cognitive, clinical, physical, and lifestyle variables. Two PCA dimensions were identified (general cognition/executive function and memory), and two MCA dimensions were retained.

The use of bayesian latent class cluster models to classify patterns of cognitive performance in healthy ageing.

The main focus of this study is to illustrate the applicability of latent class analysis in the assessment of cognitive performance profiles during ageing. Principal component analysis (PCA) was used to detect main cognitive dimensions (based on the neurocognitive test variables) and Bayesian latent class analysis (LCA) models (without constraints) were used to explore patterns of cognitive performance among community-dwelling older individuals. Gender, age and number of school years were explored as variables.
