Venetoclax (Ven) plus hypomethylating agents are considered standard-of-care for patients with acute myeloid leukemia (AML) judged ineligible for intensive chemotherapy (IC). Real-world studies complement clinical trials, since patterns of patient selection, treatment-exposure and post-remission management may vary. This prospective observational multi-center study included 209 newly diagnosed IC-ineligible patients with a median age 75 years (interquartile range, 71-81 years).

There is a global initiative to reduce the use of restrictive care practices in mental health settings. Variations in the reported rates across regions complicate the understanding of their use and tracking trends over time. However, it remains unclear whether these discrepancies reflect real differences in the implementation of these practices or are sourced from inconsistencies in incident classification and reporting methods.

In mucosal barriers, tissue cells and leukocytes collaborate to form specialized niches that support host-microbiome symbiosis. Understanding the spatial organization of these barriers is crucial for elucidating the mechanisms underlying health and disease. The gingiva, a unique mucosal barrier with significant health implications, exhibits intricate tissue architecture and likely contains specialized immunological regions.

Background: Penetrating skull base injuries are complex clinical scenarios requiring multidisciplinary management to address both immediate life-threatening conditions and long-term complications.Anterior skull base fractures account for 21% of skull fractures from which 4% were caused by head trauma [1]. Post-traumatic cerebrospinal fluid (CSF) leaks may arise, becoming a major source of morbidity; these can lead to the development of severe intracranial infections [2].

Background: Cystic fibrosis (CF) primarily affects Caucasian populations, with the highest prevalence in countries like Ireland, the UK, Australia, and Canada. Despite significant improvements in survival, pulmonary insufficiency remains the leading cause of death. Factors such as nutrition, chronic Pseudomonas aeruginosa (PsA) infection, genotype, pancreatic status, and cystic fibrosis-related diabetes affect pulmonary function across age groups.

Flagellar rotation facilitates the transfer of a bacterial conjugative plasmid.

EMBO J

January 2025

Department of Microbiology and Molecular Genetics, Institute for Medical Research Israel-Canada (IMRIC), The Hebrew University-Hadassah Medical School, POB 12272, The Hebrew University of Jerusalem, 91120, Jerusalem, Israel.

Article Synopsis
  • Conjugation-mediated DNA delivery is a key way antibiotic resistance spreads among bacteria, but the details of how this process works are not well understood.
  • The pLS20 plasmid, found in Bacillus species, uniquely requires fluid environments and induces multicellular clustering to enhance DNA transfer.
  • This study found that the pLS20 plasmid’s gene expression relies on the presence of bacterial flagella, connecting motility with the activation of conjugation during active movement, potentially spreading the plasmid to new areas.

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.

Purpose:  Fusional vergence ranges (FVR) quantify the oculomotor system's ability to overcome heterophoria, playing a critical role in diagnosis and treatment. This study investigated the effect of prism order on near vertical FVR using the smooth and step methods.

Methods:  Normal participants were randomly assigned to either the smooth or step testing method and to Base-Up (BU, infravergence) first or Base Down (BD, supravergence) first prism type.

  • This study evaluates the effectiveness of combining coalition resection and calcaneal lengthening osteotomy to treat symptomatic talocalcaneal coalition in children with painful flat feet.
  • An analysis of 10 pediatric patients showed significant improvements in foot deformities and pain levels, with most enjoying good postoperative outcomes after an average follow-up of 54 months.
  • The research concludes this combined surgical approach is effective, with minimal complications and no requirement for additional surgeries post-treatment.

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.

Background: Despite growing awareness of sex differences in inappropriate prescribing among older adults, including the initiation of problematic prescribing cascades, the impact of gender bias remains largely unexplored.

Objectives: We explored how a patient's sex and gender-related sociocultural factors influence physicians' prescribing decisions, potentially leading to prescribing cascades in older adults. A secondary objective was to explore whether and how physician sex affected prescribing decisions for female and male patients.

COPD Risk Phenotypes in Older Smokers: Evaluation in GLI- and GOLD-Defined Respiratory Impairment.

Lung

November 2024

Department of Medicine, Shaare Zedek Medical Center and Faculty of Medicine, Respiratory Research Unit, Pulmonary Institute, Hebrew University of Jerusalem, 12, Bayit Street, 91031, Jerusalem, Israel.

Purpose: In aging populations, the Global Initiative for Obstructive Lung Disease (GOLD) spirometry threshold may misclassify normal spirometry as airflow limitation. The Global Lung Initiative (GLI) method provides age-adjusted criteria. We investigated how the use of GOLD or GLI thresholds in an algorithm affects the classification of elderly smokers into COPD risk phenotypes.

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.
