Inborn errors of immunity reveal molecular requirements for generation and maintenance of human CD4 IL-9-expressing cells.

J Allergy Clin Immunol

November 2024

Garvan Institute of Medical Research, Darlinghurst, Australia; School of Clinical Medicine, Faculty of Medicine and Health, University of New South Wales (UNSW), Sydney, Australia. Electronic address:

Background: CD4 T cells play essential roles in adaptive immunity. Distinct CD4 T-cell subsets-T1, T2, T17, T22, T follicular helper, and regulatory T cells-have been identified, and their contributions to host defense and immune regulation are increasingly well defined. IL-9-producing T9 cells were first described in 2008 and appear to play both protective and pathogenic roles in human immunity.

Article Synopsis
  • This study aims to examine the histopathology and outcomes in patients with retinoblastoma who underwent eye enucleation and had neovascular glaucoma (NVG).
  • The research included 1,420 total cases from five continents, revealing that 16% of patients with NVG were often at higher risk of severe histopathological findings.
  • The findings indicate that NVG is linked to more aggressive forms of the disease and a higher chance of metastasis, emphasizing the need for careful monitoring and treatment in these cases.

The docking process is a crucial step in robotic surgery, which determines the technical capability of moving the robotic arms during surgery and affects the performance of surgery. Robotic companies, therefore, provide setup guides recommending the trocar placement, arm carts, and operating table positioning for each procedure or body quadrant, to facilitate this process. This process takes time and although improves with experience, reported docking times range from 4 to 29 min.

Article Synopsis
  • A comprehensive scale was developed to measure the burdens of three types of treatment: expected, unexpected complications, and ancillary procedure needs.
  • Expert panels assessed the burden of treatments in urology cases, calculating a burden score (BS) for different treatment options including partial nephrectomy, percutaneous ablation, radical cystectomy, and others.
  • Results indicated that less invasive treatments like percutaneous ablation and trimodal therapy had similar success rates as more invasive options, but with significantly lower burden scores, aiding in patient consultations on treatment choices.

Introduction: Universal newborn hearing screening has been successfully implemented in many places around the world, and it is recommended that cases with risk factors for hearing loss be followed-up regardless of hearing screening results. However, there is a need for clarity regarding the recommended rate of follow-up and which tests should be performed. The aim of this study was to assess the audiologic follow-up program for the group with risk factors.

Department of Developmental Biology and Cancer Research, Institute for Medical Research Israel-Canada, Hebrew University Medical School, 91120, Jerusalem, Israel.

Among the dominant pathogenic genes (PG) in breast cancer are BRCA1/2. Knowing whether a patient carry one of these alterations is meaningful as it affects management. A substantial question is to what extent are the genomic profile of a tumor and its characteristics affected by the germline profile of BRCA1/2 and what is the possible contribution of other environmental factors.

  • A phase II clinical study evaluated the effectiveness of a treatment combo (ibrutinib, bendamustine, and rituximab) in patients with relapsed or refractory aggressive B-cell non-Hodgkin lymphoma after stem cell transplants or in elderly patients.
  • The study showed a 49.1% overall response rate among patients who received at least one cycle, with better outcomes for those with relapsed disease (72.3%) versus refractory disease (37.8%).
  • Patients experiencing complete or partial responses had significantly longer median overall survival of 28.1 months, while common side effects included fatigue, diarrhea, and nausea, indicating that the treatment is both safe and effective for those needing potential transplantation.

Secondary hyperparathyroidism (SHP) associated with chronic kidney disease (CKD) contributes to morbidity and mortality, yet the related parathyroid signaling pathways are not fully understood. Previous studies have indicated that the parathyroid mTORC1 pathway is activated in both experimental CKD and hypocalcemia-induced SHP. Furthermore, mice with parathyroid-specific mTOR deficiency (PT-mTOR) exhibit disrupted parathyroid glands, but maintain normal serum PTH levels.

In recent decades, the recognition of the importance of sex, gender and their interrelationship for health research and for the practice of medicine has grown. Accordingly, the move to include gender medicine in medical school curricula has gained momentum in many countries. This article reviews the challenges of integrating this subject into medical school curricula and details the recent initiative to mainstream gender medicine into the six-year curriculum of the Hadassah-Hebrew University Medical School in Jerusalem, Israel.

Introduction: During the first waves of COVID-19 in 2020, the public was confined to their homes due to closure instructions that applied to gatherings, celebrations, and restaurants, as well as voluntary self-isolation for fear of contagion. This seclusion affected, among other things, pre-hospital emergency medical services (EMS), which experienced a general decrease in their activity for trauma cases and routine medical problems. Other immediate life-saving events are cases of anaphylaxis.

Inferring DNA methylation in non-skeletal tissues of ancient specimens.

Nat Ecol Evol

January 2025

Department of Genetics, The Alexander Silberman Institute of Life Sciences, The Hebrew University of Jerusalem, Jerusalem, Israel.

Genome-wide premortem DNA methylation patterns can be computationally reconstructed from high-coverage DNA sequences of ancient samples. Because DNA methylation is more conserved across species than across tissues, and ancient DNA is typically extracted from bones and teeth, previous works utilizing ancient DNA methylation maps focused on studying evolutionary changes in the skeletal system. Here we suggest that DNA methylation patterns in one tissue may, under certain conditions, be informative on DNA methylation patterns in other tissues of the same individual.

The management of hepatocellular carcinoma (HCC) is undergoing transformational changes due to the emergence of various novel immunotherapies and their combination with image-guided locoregional therapies. In this setting, immunotherapy is expected to become one of the standards of care in both neoadjuvant and adjuvant settings across all disease stages of HCC. Currently, more than 50 ongoing prospective clinical trials are investigating various end points for the combination of immunotherapy with both percutaneous and catheter-directed therapies.

Article Synopsis
  • The study compares the optical performance of three types of monofocal intraocular lenses (IOLs): spherical, aberration-neutral, and aberration-correcting models.
  • It uses a comprehensive approach by analyzing various corneal models and pupil sizes to account for differences in corneal spherical aberrations (SA) and pupil sizes commonly seen in both normal eyes and those post-refractive surgery.
  • Results show that pupil size and corneal SA significantly impact lens performance metrics like MTFmax (contrast at best focus), depth of focus, and refractive error tolerance, which vary based on the type of IOL used.

Pediatric Pulmonology Unit and Cystic fibrosis Center, Hadassah-Hebrew University Medical Center, Jerusalem, Israel.

Article Synopsis
  • Cystic fibrosis (CF) is a genetic disorder that primarily affects the lungs, leading to significant health issues and shortened life expectancy.
  • Despite improvements in treatment, lung function tends to decline due to early inflammation and infections, especially from pseudomonas bacteria.
  • Current treatments aim at nutrition, airway clearance, and infection control, but CFTR modulators target the underlying genetic issue, improving lung function and potentially changing the disease's progression when started early.

Taxanes and platinum molecules, specifically paclitaxel and carboplatin, are widely used anticancer drugs that induce cell death and serve as first-line chemotherapy for various cancer types. Despite the efficient effect of both drugs on cancer cell proliferation, many tumours have innate resistance against paclitaxel and carboplatin, which leads to inefficient treatment and poor survival rates. Haploid human embryonic stem cells (hESCs) are a novel and robust platform for genetic screening.
