Background: Cardiometabolic diseases, such as type 2 diabetes, hypertension, dyslipidemia or obesity, constitute major causes of mortality and morbidity worldwide, especially among middle-aged individuals. The increasing incidence and association with aging and lifestyle, render the cardiometabolic diseases a societal concern. This is further reinforced by their association with an increased risk of cognitive impairment and neurodegenerative diseases (namely dementia and Alzheimer's disease (AD)).

Histology is a preclinical subject transversal in medical, dental, and veterinary curricula. Classical teaching approaches in histology are often undermined by lower motivation and engagement of students, which may be addressed by innovative learning environments. Herein, we developed a serious game approach and compared it with a classical teaching style.

Hemophagocytic lymphohistiocytosis (HLH) is a rare clinical entity characterized by fever, constitutional symptoms, and hepatosplenomegaly associated with the presence of hemophagocytosis in the bone marrow and other organs. Visceral leishmaniasis (VL) is a severe zoonotic disease hypoendemic in Portugal, particularly in the Alto Douro region. We report the case of a 21-year-old female patient with a recent diagnosis of human immunodeficiency virus (HIV) infection, stage C3, in the context of severe pneumonia, who presented to the emergency department with fever, erythematous rash on the upper limbs and trunk, choluria and jaundice, one week after starting antiretroviral therapy (ART).

Measuring trends in extinction risk: a review of two decades of development and application of the Red List Index.

Philos Trans R Soc Lond B Biol Sci

January 2025

BirdLife International, David Attenborough Building, Pembroke Street, Cambridge CB2 3QZ, UK.

The Red List Index (RLI) is an indicator of the average extinction risk of groups of species and reflects trends in this through time. It is calculated from the number of species in each category on the IUCN Red List of Threatened Species, with trends influenced by the number moving between categories when reassessed owing to genuine improvement or deterioration in status. The global RLI is aggregated across multiple taxonomic groups and can be disaggregated to show trends for subsets of species (e.

Hydroxychloroquine-induced Sweet's Syndrome: A Case Report and Literature Review.

Acta Derm Venereol

January 2025

Dermatology Department, Unidade Local de Saúde Santa Maria, Lisbon, Portugal; Dermatology University Clinic, Faculty of Medicine, University of Lisbon, Lisbon, Portugal; Dermatology Research Unit, Instituto de Medicina Molecular, University of Lisbon, Lisbon, Portugal.

Sweet's syndrome (or acute febrile dermatosis) is a neutrophilic dermatosis with a characteristic presentation encompassing specific clinical (fever and erythemato-violaceous oedematous papules, plaques and nodules), laboratory (neutrophilia and increased inflammatory markers), and histological (dermal neutrophilic infiltrate without vasculitis) features. Its pathophysiology is poorly understood but there seems to be an auto-inflammatory component related to mutations in inflammasome genes. It has been subdivided into its classic form, malignancy-associated, and drug-induced, according to its aetiology.

Are Animal Models Necessary? Exploring (Dis)advantages and Alternatives.

Eur J Neurosci

January 2025

Pharmacology and Neurobiology Laboratory of the Immunophysiology and Pharmacology Department, School of Medicine and Biomedical Sciences (ICBAS), University of Porto, Porto, Portugal.

Animal models have been crucial for scientific development, allowing researchers to understand the underlying mechanisms of various human conditions, and are far from becoming obsolete in scientific research. However, the ethics of animal experimentation has been a prevalent question between both experts and nonexperts. This essay tackles the advantages and disadvantages of the usage of animal models while delving into new alternatives that have emerged in light of contemporary science.

Iatrogenic intramural esophageal hematoma during EUS-B-FNA procedure.

BMC Pulm Med

January 2025

Unidade de Broncologia e Pneumologia de Intervenção - Instituto Português de Oncologia Francisco Gentil, Coimbra, Portugal.

Background: Esophageal ultrasound with bronchoscope fine needle aspiration (EUS-B-FNA) is a valuable tool for the diagnosis and staging of lung cancer, complementing endobronchial lung ultrasound (EBUS). While generally considered safe, there is a notable lack of comprehensive knowledge within the interventional pulmonology community regarding potential complications.

Case Presentation: We present a case involving a 66-year-old male with squamous cell lung carcinoma undergoing mediastinal staging.

Background: Dialysis recovery time (DRT) refers to the period during which fatigue and weakness subside following hemodialysis treatment, allowing patients to resume their daily routines. This study aimed to identify the factors influencing DRT in hemodialysis patients in Turkey and Portugal, where the prevalence of chronic kidney disease is notably high.

Methods: A cross-sectional observational study was conducted in a private dialysis center in Turkey and three dialysis centers in Portugal.

Complete datasets of genetic variants are key to biodiversity genomic studies. Long-read sequencing technologies allow the routine assembly of highly contiguous, haplotype-resolved reference genomes. However, even when complete, reference genomes from a single individual may bias downstream analyses and fail to adequately represent genetic diversity within a population or species.

Layer-by-Layer (LbL) self-assembly encapsulation is a promising technology for the protection and delivery of lactic acid bacteria. However, laboratory-scale encapsulation is often time-consuming, involves intensive protocols tailored for small-scale operations, requires substantial amounts of energy and water, and results in a low yield of encapsulated biomass. Scaling-up this process to a bench-bioreactor scale is not simply a matter of increasing culture volume as different key parameters (not particularly relevant at lab scale) become critical, including biomass production, the number of polymer layers, and the biomass-to-polymer mass ratio.

Biodiversity spatial distribution of benthic macroinvertebrate assemblages is influenced by anthropogenic disturbances at multiple spatial extents.

Sci Total Environ

January 2025

Universidade Federal de Minas Gerais, Instituto de Ciências Biológicas, Departamento de Genética, Ecologia e Evolução, Laboratório de Ecologia de Bentos, Av. Antônio Carlos 6627, Pampulha, 31270-901 Belo Horizonte, MG, Brazil.

Understanding the patterns and mechanisms of biodiversity and its organization in space is essential for developing effective conservation strategies. Zeta diversity is an index of how taxa are shared by several sites, providing information on how ecological filters, including anthropogenic disturbances, influence biodiversity distribution. This study documents how anthropogenic disturbances at multiple spatial extents affect the spatial variation of benthic macroinvertebrate assemblages in lotic ecosystems.
