Ophthalmic Genetics Group, Institute of Molecular and Clinical Ophthalmology Basel, 4031 Basel, Switzerland; Department of Ophthalmology, Universität Basel, 4031 Basel, Switzerland; Department of Genetics and Genome Biology, University of Leicester, Leicester LE1 7RH, UK. Electronic address:

Retinitis pigmentosa (RP) is a Mendelian disease characterized by gradual loss of vision, due to the progressive degeneration of retinal cells. Genetically, it is highly heterogeneous, with pathogenic variants identified in more than 100 genes so far. Following a large-scale sequencing screening, we identified five individuals (four families) with recessive and non-syndromic RP, carrying as well bi-allelic DNA changes in COQ8B, a gene involved in the biosynthesis of coenzyme Q10.

Introduction: Developed by the Global Vascular Guidelines committee, the Global Limb Anatomic Staging System (GLASS) is an angiographic scoring system used for quantifying infrainguinal disease extent and predicting treatment success with endovascular techniques (EVT). Currently, no other risk prediction model is available for patients with chronic limb threatening ischemia (CLTI) undergoing EVT. GLASS' validation and adoption outside academic institutions for research are limited.

: Male stress urinary incontinence (SUI) after surgical treatment of benign prostatic enlargement (BPE) is an infrequent but dreadful complication and constitutes a therapeutic challenge. The efficacy and safety of the adjustable trans-obturator male system (ATOMS) in these patients is rather unknown, mainly due to the rarity of this condition. We aimed to assess the results of ATOMS to treat SUI after transurethral resection (TURP) or holmium laser enucleation (HoLEP) of the prostate.

The combination of cyclin-dependent kinase 4/6 inhibitors (CDK4/6i) with endocrine therapy (ET) is the standard-of-care for estrogen receptor (ER)-positive, HER2-negative (ER+/HER2- advanced/metastatic breast cancer (mBC). However, the impact of CDK4/6i on circulating immune cells and circulating tumor cells (CTCs) in patients receiving CDK4/6i and ET (CDK4/6i+ET) remains poorly understood. This was a prospective cohort study including 44 patients with ER+/HER2- mBC treated with CDK4/6i+ET in either first or second line.

Impact of an Exercise-Based Cardiac Rehabilitation Program on Cardiopulmonary Test Parameters.

Cardiology

August 2024

Cardiology Service, Heart and Vessels Department, Centro Hospitalar Universitário Lisboa Norte, CAML, CCUL, Faculty of Medicine of the University of Lisbon, Lisbon, Portugal.

Introduction: Exercise-based cardiac rehabilitation programs (CRPs) represent a multidisciplinary therapeutic approach tailored to improve cardiorespiratory fitness and overall health-related quality of life, while reducing cardiovascular hospitalizations and mortality. Our aim was to determine changes in exercise capacity and cardiac events according to the left ventricular ejection fraction (LVEF) following a CRP.

Methods: This single-center cohort study included 131 patients who completed a center-based CRP from 2015 to 2022.

Article Synopsis
  • - The study aimed to understand the natural history and prognostic factors of porto-sinusoidal vascular disorder (PSVD) by analyzing a large cohort of 587 patients across 27 centers, finding that the majority were asymptomatic at diagnosis, but many experienced complications related to portal hypertension.
  • - Over a median follow-up of 68 months, 8.5% of patients underwent liver transplantation, while 19% died, highlighting significant risks like portal hypertension-related bleeding and ascites, as well as the impact of age and liver function on prognosis.
  • - The findings indicate that the severity of underlying conditions and liver/renal function significantly influence survival chances, leading to the development of a nomogram for more accurate prognosis prediction in

Study of seasonality of attacks in MOG antibody-associated disease.

Mult Scler Relat Disord

October 2024

Nuffield Department of Clinical Neurosciences, University of Oxford, UK. Electronic address:

Article Synopsis
  • Some studies suggest that attacks of acute disseminated encephalomyelitis (ADEM) may vary with the seasons, and up to 50% of ADEM cases have myelin oligodendrocyte glycoprotein (MOG) antibodies.
  • This study analyzed data from the Oxford-based NMO Service database to examine potential seasonal effects on MOG antibody-associated disease (MOGAD) attacks from 2010 to 2021.
  • The findings indicated that there were no significant seasonal variations in the frequency of total or onset MOGAD attacks in the UK.

  • Atrial fibrillation (AF) is a common issue in cancer patients, and this study aims to evaluate their clinical characteristics and management, particularly focusing on antithrombotic medications.
  • The study involved 1,514 patients with recent cancer diagnoses and confirmed AF, finding high rates of cardiovascular diseases and a significant number of patients not receiving optimal anticoagulation treatment upon admission.
  • Results indicate a significant underuse of appropriate antithrombotic therapy, suggesting the necessity for improved cardiovascular assessments in the care of cancer patients with AF.

Article Synopsis
  • - Lung cancer is a major global health issue, and low-dose computed tomography (LDCT) screening can reduce mortality rates by up to 25%, making it a cost-effective solution that European countries are encouraged to explore for implementation.
  • - A task force reviewed literature and engaged in discussions to develop recommendations for launching lung cancer screening programs in Portugal, focusing on the guidelines of the World Health Organization tailored to the local healthcare system.
  • - Key areas covered in the recommendations include identifying eligible populations, invitation methods, radiological requirements, result reporting, referral processes, and the integration of smoking cessation programs as essential for effective lung cancer screening.

Article Synopsis
  • * The condition was diagnosed as a fixed drug eruption (FDE) linked to an allergic reaction from radiocontrast used during the procedure, confirmed by medical history and positive drug testing.
  • * Delayed hypersensitivity reactions (DHRs) can occur after contrast administration, and while skin tests help identify allergens, premedication with corticosteroids may reduce the severity of these reactions.

Preoperative statin therapy for adults undergoing cardiac surgery.

Cochrane Database Syst Rev

July 2024

Department of Cardiology/Heart and Vessels, Hospital de Santa Maria, Centro Hospitalar Universitário Lisboa Norte (CHULN), CAML, CCUL@RISE, Faculdade de Medicina, Universidade de Lisboa, Lisbon, Portugal.

Background: Despite significant advances in surgical techniques and perioperative care, people undertaking cardiac surgery due to cardiovascular disease are more prone to the development of postoperative adverse events. Statins (5-hydroxy-3-methylglutaryl-co-enzyme A (HMG-CoA) reductase inhibitors) are well-known for their anti-inflammatory and antioxidant effects and are established for primary and secondary prevention of coronary artery disease. In addition, statins are thought to have clinical benefits in perioperative outcomes in people undergoing cardiac surgery.
