Article Synopsis
  • Vaginal laxity (VL) is often linked to pelvic floor dysfunction, but its causes are not fully understood; this study aimed to explore the connection between childbirth history and VL.
  • A study of over 1,000 women revealed that 23% reported VL, with younger and less menopausal women being more affected, and symptoms of prolapse were significantly higher in this group.
  • Results indicated that women who had vaginal deliveries were three times more likely to experience VL than those who only had cesarean sections, with evidence suggesting that the first delivery has the most significant impact on VL symptoms.

Genetic engineering of immune cells has opened new avenues for improving their functionality but it remains a challenge to pinpoint which genes or combination of genes are the most beneficial to target. Here, we conduct High Multiplicity of Perturbations and Cellular Indexing of Transcriptomes and Epitopes (HMPCITE-seq) to find combinations of genes whose joint targeting improves antigen-presenting cell activity and enhances their ability to activate T cells. Specifically, we perform two genome-wide CRISPR screens in bone marrow dendritic cells and identify negative regulators of CD86, that participate in the co-stimulation programs, including Chd4, Stat5b, Egr2, Med12, and positive regulators of PD-L1, that participate in the co-inhibitory programs, including Sptlc2, Nckap1l, and Pi4kb.

Goldyne Savad Institute of Gene Therapy, Hadassah Medical Center, The Faculty of Medicine, The Hebrew University of Jerusalem, Jerusalem, Israel.

GNE myopathy is an adult onset neuromuscular disorder characterized by slowly progressive distal and proximal muscle weakness, caused by missense recessive mutations in the gene. Although the encoded bifunctional enzyme is well known as the limiting factor in the biosynthesis of sialic acid, no clear mechanisms have been recognized to account for the muscle atrophic pathology, and novel functions for GNE have been hypothesized. Two major issues impair studies on this protein.

Therapeutic strategies for advanced head and neck squamous carcinoma (HNSCC) consist of multimodal treatment, including Epidermal Growth Factor Receptor (EGFR) inhibition, immune-checkpoint inhibition, and radio (chemo) therapy. Although over 90% of HNSCC tumors overexpress EGFR, attempts to replace cytotoxic treatments with anti-EGFR agents have failed due to alternative signaling pathways and inter-tumor heterogeneity. Using protein expression data obtained from hundreds of HNSCC tissues and cell lines we compute individualized signaling signatures using an information-theoretic approach.

Torticollis in children can be a sign of a potentially dangerous disease; the correct diagnosis is not always obvious on history and physical examination. The use of point-of-care ultrasound (POCUS) helps to limit the differential diagnosis and direct appropriate further laboratory and radiology-performed evaluation. We present a case of a 10-year-old child whose deep neck infection (DNI) was timely diagnosed in the paediatric emergency department by early use of POCUS and drained under POCUS guidance after admission to the hospital.
