High Preoperative T1 Slope is a Marker for Global Sagittal Malalignment.

Study Design: Retrospective cohort study.

Objective: To develop parameter thresholds obtainable from cervical radiographs that correlate with concomitant thoracolumbar malalignment.

Summary Of Background Data: T1 slope (T1S) is typically discussed in the context of cervical deformity and correlated with health-related quality of life outcomes.

The healthcare experiences of rural-living Canadians with and without a primary care provider: a qualitative analysis of open-ended cross-sectional survey responses.

Aim: This study aimed to explore healthcare experiences of rural-living patients both with (attached) and without (unattached) a local primary care provider.

Background: Primary care providers serve a gatekeeping role in the Canadian healthcare system as the first contact for receiving many health services. With the shortage of primary care providers, especially in rural areas, there is a need to explore attached and unattached patient experiences when accessing healthcare.

Single cell and spatial analysis of immune-hot and immune-cold tumours identifies fibroblast subtypes associated with distinct immunological niches and positive immunotherapy response.

Cancer-associated Fibroblasts (CAFs) have emerged as critical regulators of anti-tumour immunity, with both beneficial and detrimental properties that remain poorly characterised. To investigate this, we performed single-cell and spatial transcriptomic analysis, comparing head & neck squamous cell carcinoma (HNSCC) subgroups, which although heterogenous, can be considered broadly immune-hot and immune-cold (human papillomavirus [HPV]+ve and HPV-ve tumours respectively). This identified six fibroblast subpopulations, including two with immunomodulatory gene expression profiles (IL-11 + inflammatory [i]CAF and CCL19 + fibroblastic reticular cell [FRC]-like).

Fixation Methods, Complications, and Outcomes After Primary Fixation of Isolated Chondral Fragments in the Knee: A Systematic Review.

Background: Knee injuries resulting in purely cartilaginous defects are rare, and controversy remains regarding the reliability of chondral-only fixation.

Purpose: To systematically review the literature for fixation methods and outcomes after primary fixation of chondral-only defects within the knee.

Study Design: Systematic review; Level of evidence, 5.

Amniotic Fluid as a Potential Treatment for Vocal Fold Scar in a Rabbit Model.

Objectives/hypothesis: Vocal fold (VF) injury and chronic inflammation can progress to scarring, which is notoriously difficult to treat. Human amniotic fluid (AF) has potential for VF wound healing in a rabbit model, and we hypothesized that AF would demonstrate wound healing properties superior to hyaluronic acid (HA) over time.

Study Design: Randomized, controlled trial.
