Impact of aortic and pulmonary artery wall histology on radicular dilatation during the Ross procedure.

J Cardiothorac Surg

November 2024

Department of Cardiac Surgery, Amiens Picardie University Hospital Center, 1 Rue du Professeur Christian Cabrol, 80054, Amiens, Cedex1, France.

Article Synopsis
  • The study investigates the structural differences between the aortic root and pulmonary artery to understand how the pulmonary autograft dilates during the Ross procedure.
  • Samples from twenty fetuses and four adults were analyzed using various histological and immunohistochemical techniques to compare elastic laminae and smooth muscle cells in both arterial walls.
  • In adults, significant differences were found in these structures, suggesting that these microscopic variations influence the mechanical behavior of the pulmonary autograft and contribute to its dilation under systemic pressure after the procedure.

  • Hematological involvement (HI) is a serious condition associated with Langerhans cell histiocytosis (LCH), and is defined by low blood cell counts indicating potential life-threatening complications.
  • A study of 2,313 children with LCH revealed that about 331 developed HI, with a distinction between mild (MHI) and severe HI (SHI), each showing different health outcomes and survival rates over 10 years.
  • Recent advances in treatment have improved mortality rates, particularly with combination therapies and targeted treatments, sparking discussions about refining HI definitions to better inform treatment strategies.

Encephalitis with antibodies to leucine-rich glioma-inactivated 1 (LGI1-Ab-E) is a common form of autoimmune encephalitis, presenting with seizures and neuropsychiatric changes, predominantly in older males. More than 90% of patients carry the human leucocyte antigen (HLA) class II allele, HLA-DRB1*07:01. However, this is also present in 25% of healthy controls.

Efficacy of first-line immune checkpoint inhibitors in pulmonary sarcomatoid carcinoma.

Transl Lung Cancer Res

September 2024

Pneumology Department, Thoracic Oncology Unit, Cochin Hospital, AP-HP, Paris Cité University, Paris, France.

Background: Pulmonary sarcomatoid carcinomas (PSC) are notorious for their poor prognosis and resistance to chemotherapy. The literature suggests that immunotherapy might be effective against this aggressive tumor. This study aims to evaluate the efficacy of immunotherapy, either alone or combined with chemotherapy, as first-line treatment for PSC patients.

Article Synopsis
  • - The study evaluated how different resin composites cured under various CAD/CAM materials (like zirconia and glass ceramic) of different thicknesses impacted the depth of cure (DOC), using microhardness testing.
  • - It was found that as the thickness of the CAD/CAM materials increased, the DOC decreased, and the performance of resin composites varied based on their chemical makeup and the curing mode used.
  • - Among the materials tested, Tetric PowerFill exhibited the highest DOC, and the study suggested that using receiver operating characteristic models was more effective in predicting curing performance than traditional linear regression.

Purpose: This prospective clinical cohort was undertaken to determine the long-term risks of reinfection and all-cause aseptic failure after 1-stage exchange total knee arthroplasties (TKA) in a large series of consecutive patients with periprosthetic joint infection (PJI) following TKA.

Hypothesis: One-stage exchange for chronic PJI is an effective strategy, even in a non-selected population.

Patients And Methods: Non-selected patients (152 with 154 PJI) undergoing 1-stage-exchange TKA for PJI (January 2003-August 2015) were prospectively included and monitored for ≥2 years.

Article Synopsis
  • - The study analyzed 79 patients with severe tuberculosis-related ARDS who received ECMO treatment at 20 centers worldwide, focusing on their 90-day survival rates and related complications.
  • - Results showed that 51% of patients survived for 90 days, with significant complications including major bleeding and infections; miliary TB patients had a notably higher survival rate than those with cavitary TB.
  • - Factors like older age, drug-resistant TB, and higher pre-ECMO SOFA scores were identified as key predictors of mortality, suggesting that ECMO could be a valuable intervention for patients with TB-induced ARDS.

Article Synopsis
  • Improving care for older adults with end-stage kidney disease (ESKD) involves adapting medical standards to their unique needs, which can be complicated by factors like multiple health conditions and cognitive decline.
  • *Nephrologists face daily challenges in decision-making regarding treatment options, given the uncertain benefits and risks for this diverse population.
  • *The review emphasizes the importance of shared decision-making and suggests enhancing collaboration between gerontology and nephrology, while also calling for more research to fill existing gaps in knowledge.

Indeterminate DC histiocytosis is distinct from LCH and often associated with other hematopoietic neoplasms.

Blood Adv

Department of Pathology, Ambroise-Paré Hospital, Assistance Publique-Hôpitaux de Paris (AP-HP), & EA4340-Biomarkers and clinical trials in Cancerology and Onco-Hematology, Versailles SQY University, Paris-Saclay University, Boulogne, France.

Article Synopsis
  • Indeterminate dendritic cell histiocytosis (IDCH) is a rare condition marked by a buildup of specific histiocytes, with particular immunophenotypic features and clinical presentations, mostly in older adults.
  • The study analyzed 43 cases, showing that many patients had skin or lymph node involvement, and a significant number had related blood cancers or other histiocytic diseases.
  • Genetic analyses identified common mutations (like KRAS and BRAF) and unique gene fusions, helping to clarify IDCH's molecular profile and its potential impact on diagnosis and treatment strategies.

Background: Right ventricle impairment (RVI) is common during acute respiratory distress syndrome (ARDS) in adults and children, possibly mediated by the level of transpulmonary pressure (P). We sought to investigate the impact of the level of P on ARDS-associated right ventricle impairment (RVI).

Methods: Adults and children (> 72 h of life) were included in this two centers prospective study if they were ventilated for a new-onset ARDS or pediatric ARDS, without spontaneous breathing and contra-indication to esophageal catheter.

Background: Glaucoma is a leading cause of blindness, affecting retinal ganglion cells (RGCs) and their axons. By 2040, it is likely to affect 110 million people. Neuroinflammation, specifically through the release of proinflammatory cytokines by M1 microglial cells, plays a crucial role in glaucoma progression.

The surgical management of posterior cruciate ligament (PCL) injuries can be challenging. As most PCL injuries occur in a flexed knee position, the anterolateral bundle is thought to be more commonly injured than the posteromedial bundle (PMB); however, in hyperextension, the PMB plays a more significant role. The smaller size of the PMB compared with the anterolateral bundle and its lower strength may explain why isolated hyperextension PMB injuries can be easily overlooked.

Flecainide to Prevent Atrial Arrhythmia After Patent Foramen Ovale Closure: AFLOAT Study, A Randomized Clinical Trial.

Circulation

November 2024

ACTION Study Group, INSERM UMRS1166, ICAN-Institute of Cardiometabolism and Nutrition, Sorbonne Université (P.G., M.L., T.R., Y.T., M.E.G., D.B., J.S., N.H., G.D., G.M.), Institut de Cardiologie, Hôpital Pitié-Salpêtrière (AP-HP), Paris, France.

Background: The real incidence of atrial arrhythmia (AA) after patent foramen ovale (PFO) closure and whether this complication can be prevented remain unknown. We assessed whether flecainide is effective to prevent AA during the first 3 months after PFO closure, and whether 6 months of treatment with flecainide is more effective than 3 months to prevent AA after PFO closure.

Methods: AFLOAT (Assessment of Flecainide to Lower the Patent Foramen Ovale Closure Risk of Atrial Fibrillation or Tachycardia Trial) is a prospective, multicentre, randomized, open-label, superiority trial with a blind evaluation of all the end points (PROBE [Prospective Randomized Open, Blinded End Point] design).
