Diabetes mellitus is a significant risk factor for the development of heart disease (HD), with heart failure (HF) being one of the early manifestations of the disease in this population. The diagnostic process is challenging and contributes to a significant number of undiagnosed cases of HD among individuals with diabetes. This is largely due to the non-specific nature of symptoms and signs in the initial stages of disease, making early detection elusive.

A prolonged intensive care unit stay defines a worse long-term prognosis - Insights from the critically ill mortality by age (Cimba) study.

Aust Crit Care

September 2024

Clinica Universitária de Medicina Intensiva, FMUL, Lisbon, Portugal; Intensive Care Department, Hospital St(a) Maria, Lisbon, Portugal; Grupo Infeção e Desenvolvimento em Sépsis (GIS-ID), Porto, Portugal. Electronic address:

Article Synopsis
  • Patients with critical illnesses often face longer stays in the ICU, resulting in slower recovery and increased long-term health risks, particularly in older or frail individuals.
  • This study analyzed data from over 37,000 ICU patients to compare outcomes between those with short (<14 days) and prolonged (≥14 days) ICU stays, identifying key risk factors for sustained critical illness.
  • Results showed that patients with prolonged stays were generally younger but more severely ill, facing higher mortality rates in the ICU, hospital, and long-term, emphasizing the need for improved care planning based on these findings.

May 2024

Arthur and Sonia Labatt Brain Tumor Research Centre, Toronto, ON, Canada; Division of Hematology and Oncology, The Hospital for Sick Children, Toronto, ON, Canada. Electronic address:

Background: Constitutional mismatch repair deficiency (CMMRD) syndrome is a rare and aggressive cancer predisposition syndrome. Because a scarcity of data on this condition contributes to management challenges and poor outcomes, we aimed to describe the clinical spectrum, cancer biology, and impact of genetics on patient survival in CMMRD.

Methods: In this cohort study, we collected cross-sectional and longitudinal data on all patients with CMMRD, with no age limits, registered with the International Replication Repair Deficiency Consortium (IRRDC) across more than 50 countries.

Electronic address:

Influenza affects millions of people worldwide each year and can lead to severe complications, hospitalizations, and even death, especially among vulnerable populations such as older adults and those with chronic medical conditions. Annual vaccination is considered the most effective measure for preventing influenza and its complications. Despite the widespread availability of influenza vaccines, however, vaccination coverage rates remain suboptimal in several countries.

Inborn Metabolic Disorders Reference Center, Pediatrics Department, Hospital de São João, Porto, Portugal.

Introduction: Long-chain fatty acid oxidation disorders (LC-FAOD) are inborn errors of metabolism, also identified in newborn screening in Portugal. They interfere with adequate energy utilization, namely by muscles, heart, and liver. Treatment aims to maintain patients in an anabolic state, with increased caloric intake, using carbohydrates and medium-chain fatty acids.

Glucose homeostasis is essential for energy production and the central nervous system function, depending on glycogen metabolism. Glycogen storage diseases (GSD) are caused by enzymatic defects of the glycogen degradation and mainly involve the liver since the inhibition of hepatic glycogen breakdown results in its excessive storage and hepatomegaly. Other findings are hypoglycemia and hyperlactatemia and consequent neurological symptoms.

Beyond genetics: Deciphering the impact of missense variants in CAD deficiency.

J Inherit Metab Dis

November 2023

Structure of Macromolecular Targets Unit, Instituto de Biomedicina de Valencia (IBV), CSIC, Valencia, Spain.

Article Synopsis
  • - CAD is a crucial protein involved in making pyrimidines, and mutations can lead to developmental and epileptic issues that respond well to uridine supplements, but diagnosing CAD deficiency is challenging due to vague symptoms and numerous variants.
  • - Researchers evaluated 20 newly identified missense variants of CAD, finding 11 pathogenic ones that would benefit from treatment, while also confirming some known variants as damaging and classifying others as likely benign.
  • - By studying the dihydroorotase (DHO) domain of CAD through atomic-resolution structures and functional tests, the research aims to enhance the understanding of CAD's function and improve diagnostic methods for detecting pathogenic variants.

Introduction: Liquid biopsies based on plasma circulating tumour deoxyribonucleic acid (ctDNA) have shown promise in monitoring lung cancer evolution. The expression of ctDNA across time, its relationship with clinicopathological parameters and its association with lung cancer progression through imaging allow us to weigh how useful ctDNA could be in monitoring surgically resectable lung cancer. The aim of this study was to assess the impact of ctDNA analysis implementation in early-stage lung cancer.
