Despite the benefits of minimally invasive surgery, interventions such as laparoscopic liver surgery present unique challenges, like the significant anatomical differences between preoperative images and intraoperative scenes due to pneumoperitoneum, patient pose, and organ manipulation by surgical instruments. To address these challenges, a method for intraoperative three-dimensional reconstruction of the surgical scene, including vessels and tumors, without altering the surgical workflow, is proposed. The technique combines neural radiance field reconstructions from tracked laparoscopic videos with ultrasound three-dimensional compounding.

It has proven difficult to establish robust evidence for significant clinical benefits of medical treatment in primary sclerosing cholangitis (PSC). For ursodeoxycholic acid, clinical practice guidelines only offer vague recommendations, leading to a situation of variable prescription rates depending on local reimbursement policies and physician preference. The difficulty in drug development in PSC is partly related to a poor understanding of critical disease processes with failure to identify relevant mechanisms of action of putative drugs.

J Allergy Clin Immunol

November 2024

Laboratory for Paediatric Immunology, Willem-Alexander Children's Hospital, Leiden University Medical Center, Leiden, The Netherlands. Electronic address:

Article Synopsis
  • Newborn screening (NBS) programs in Europe started in the 1960s, expanding recently to include testing for severe combined immunodeficiency (SCID) through T-cell receptor excision circles (TRECs).
  • A survey sent to 46 European countries collected comprehensive data, with 38 countries responding, revealing that 17 have already implemented TREC-based NBS.
  • The findings indicate a need to reassess the definition of the target disease to include conditions beyond SCID and highlight the importance of international collaboration for improving universal TREC-based screening.

Tertiary Lymphoid Structures (TLS) are organized aggregates of immune cells such as T cells, B cells, and Dendritic Cells (DCs), as well as fibroblasts, formed postnatally in response to signals from cytokines and chemokines. Central to the function of TLS are DCs, professional antigen-presenting cells (APCs) that coordinate the adaptive immune response, and which can be classified into different subsets, with specific functions, and markers. In this article, we review current data on the contribution of different DC subsets to TLS function in cancer and autoimmunity, two opposite sides of the immune response.

Article Synopsis
  • The study aimed to compare immune responses to a COVID-19 booster vaccination between older adults and younger individuals, focusing on humoral and cellular immunity.
  • Researchers found that older adults (average age 86) initially had lower immune responses after earlier vaccinations compared to younger adults (average age 39), but both groups improved their antibody levels after the booster.
  • While young adults showed increased cellular immune responses after the booster, older adults did not, and their plasma showed higher levels of certain T cell activation and exhaustion markers, indicating potential immune dysfunction in the elderly.
