Autoimmune hemolytic anemia (AIHA) is an uncommon but recognized complication of a hematopoietic stem cell transplant (HSCT). Management challenges include the absence of established guidelines and variable response rates to first-line treatments. We present a case series of three patients, all submitted to HSCT for non-oncologic diseases, who developed AIHA as a complication in the following months.

November 2024

Neurology, Department of Neurosciences and Mental Health, Hospital de Santa Maria, Unidade Local de Saúde Santa Maria, Lisbon, Portugal; Centro de Estudos Egas Moniz, Faculdade de Medicina, Universidade de Lisboa, Lisbon, Portugal.

Article Synopsis
  • Posterior reversible encephalopathy syndrome (PRES) is a rare condition affecting the white matter of the brain and can present similarly to other neurological disorders.
  • The case discussed involves a 63-year-old man with multiple sclerosis undergoing interferon beta therapy, who experienced sudden symptoms resembling a relapse due to PRES.
  • This highlights the need for careful clinical evaluation in older patients with multiple sclerosis, as it may require adjusting their treatment for better outcomes.

Introduction And Importance: Acute lower gastrointestinal bleeding is one of the most common causes of hospital admission. However, massive bleeding is uncommon and is mainly due to hemorrhoidal bleeding in elderly patients receiving anticoagulant therapy. We present a rare case of a massive rectal haemorrhage with an uncommon cause.

Background: Speech production is a possible way to monitor bulbar and respiratory functions in patients with amyotrophic lateral sclerosis (ALS). Moreover, the emergence of smartphone-based data collection offers a promising approach to reduce frequent hospital visits and enhance patient outcomes. Here, we studied the relationship between bulbar and respiratory functions with voice characteristics of ALS patients, alongside a speech therapist's evaluation, at the convenience of using a simple smartphone.

Objective: To optimise the organisation of care and encourage the adoption of good clinical practices, the RarERN Path methodology was designed within ERN ReCONNET. The aim of our work was to report the application of RarERN Path on systemic sclerosis within the ERN ReCONNET centres, providing a feasible and flexible organisational reference model for optimising the systemic sclerosis care pathway in different countries.

Methods: RarERN Path is a six-phase methodology which enables the creation of a reference organisational model co-designed on the basis of the expertise of different stakeholders.

Decoding mutational hotspots in human disease through the gene modules governing thymic regulatory T cells.

Front Immunol

November 2024

Instituto de Medicina Molecular João Lobo Antunes, Faculdade de Medicina, Universidade de Lisboa, Lisboa, Portugal.

Computational strategies to extract meaningful biological information from multiomics data are in great demand for effective clinical use, particularly in complex immune-mediated disorders. Regulatory T cells (Tregs) are essential for immune homeostasis and self-tolerance, controlling inflammatory and autoimmune processes in many diseases with a multigenic basis. Here, we quantify the Transcription Factor (TF) differential occupancy landscape to uncover the Gene Regulatory Modules governing lineage-committed Tregs in the human thymus, and show that it can be used as a tool to prioritise variants in complex diseases.

Electronic address:

Objectives: The "split-hand syndrome" is a common clinical sign in amyotrophic lateral sclerosis (ALS), being characterized by more severe atrophy of the hand muscles on the radial side of the hand compared to the ulnar side. We aimed to investigate possible physiological differences between relevant hand muscles using low-intensity F-wave stimulation to assess spinal motoneuron excitability.

Methods: We recruited 36 healthy volunteers.

Cardiophrenic Lymph Node Resection Through Abdominal Subxiphoid Approach: Surgical Technique.

Surg Technol Int

October 2024

Department of Digestive, Hepatobiliary, and Liver Transplantation Surgery, AP-HP, Hôpital de la Pitié-Salpêtrière, Paris, France.

While metastatic extension to the cardiophrenic lymph nodes (CPN) is relatively rare, cardiophrenic lymphadenectomy may be performed for diagnostic and/or therapeutic purposes. The subxiphoid approach is appropriate, especially for CPN in the prepericardiac area, offering adequate exposure while avoiding the morbidity associated with pleural or pericardial breach. In this article, we describe the surgical technique-detailing the retrosternal liberation section of the tranversus abdominis muscle, followed by cardiophrenic dissection and lymphadenectomy.

A global effort to benchmark predictive models and reveal mechanistic diversity in long-term stroke outcomes.

bioRxiv

November 2024

Groupe d'Imagerie Neurofonctionnelle, Institut des Maladies Neurodégénératives-UMR 5293, Centre national de la recherche scientifique (CNRS), CEA, University of Bordeaux, Bordeaux, France.

Stroke remains a leading cause of mortality and long-term disability worldwide, with variable recovery trajectories posing substantial challenges in anticipating post-event care and rehabilitation planning. In response, we established the NeuralCup consortium to address these challenges by benchmarking predictive models of stroke outcome through a collaborative, data-driven approach. This study presents the findings of 15 participating teams worldwide who used a comprehensive dataset including clinical and imaging data, to identify and compare predictors of motor, cognitive, and emotional outcomes one-year post-stroke.

Article Synopsis
  • The study introduces a new technique called multielectrode catheter-induced ectopy mapping (MECIE mapping) to help locate the origins of infrequent premature ventricular complexes (PVCs) for effective ablation treatment.
  • Researchers enrolled 29 patients with infrequent PVCs and used MECIE mapping to create a detailed local activation time map, achieving high concordance with the clinical PVCs.
  • After an average follow-up of about 13 months, 93.1% of the patients experienced an 80% or greater reduction in PVCs, indicating that MECIE mapping is a promising strategy for successful PVC ablation.

Article Synopsis
  • The study analyzed the clinical characteristics of female Obstructive Sleep Apnoea (OSA) patients from the European Sleep Apnoea Database, using data from 9,710 participants.
  • Four distinct clusters or phenotypes of women with OSA were identified, each with varying age, BMI, comorbidities, and severity of sleep apnea.
  • The findings suggest that gender-specific phenotyping could lead to better risk assessment and tailored treatment options for women with OSA.

Article Synopsis
  • In the TOPAZ-1 trial, patients with biliary tract cancers (BTC) who had recurrence within 6 months of surgery were excluded, which often happens in practice. This study looked into the effectiveness of cisplatin-gemcitabine-durvalumab (CGD) in patients who did experience early recurrence.
  • The study enrolled 178 BTC patients who had surgery and then underwent treatment with CGD after experiencing either early or late disease recurrence. Key goals were to measure overall survival (OS) and progression-free survival (PFS).
  • Results showed no significant differences in OS and PFS between early and late relapse groups, suggesting CGD is effective regardless of when the cancer

Digital health interventions including telehealth, mobile health, artificial intelligence, big data, robotics, extended reality, computational and high-fidelity bench simulations are an integral part of the path toward precision medicine. Current applications encompass risk factor modification, chronic disease management, clinical decision support, diagnostics interpretation, preprocedural planning, evidence generation, education, and training. Despite the acknowledged potential, their development and implementation have faced several challenges and constraints, meaning few digital health tools have reached daily clinical practice.
