Diabetes mellitus is generally considered a risk factor for impaired wound healing. This study aimed to evaluate the glycaemic status of patients undergoing neck dissection and describe its impact on postoperative outcomes, especially wound healing. A retrospective analysis was performed of the preoperative, intraoperative, and postoperative glycaemic data obtained from the medical charts of 60 adult patients who had undergone 64 neck dissections. Nine of the 64 procedures were performed in diabetic patients (14.1%). The average glucose values were: preoperative 5.99 ± 1.25 mmol/l, intraoperative 8.90 ± 2.62 mmol/l, and postoperative 10.01 ± 2.49 mmol/l. All registered preoperative hyperglycaemia cases (eight cases) were diabetic. Postoperative insulin therapy was done in 14 procedures (21.9%). Wound healing complications were found in five patients (7.8%); there was no wound infection. There was no association of wound healing complications with preoperative diabetic status (P = 1.000), preoperative glucose control (P = 1.000), preoperative (P=0.469), intraoperative (P = 0.248), and postoperative (P = 0.158) glucose values, or with postoperative glucose control (P = 0.577). These data do not support the association of stress-induced hyperglycaemia or diabetes mellitus with postoperative wound healing problems in neck dissection.

Background: Immune cells within tumor tissues play important roles in remodeling the tumor microenvironment, thus affecting tumor progression and the therapeutic response. The current study was designed to identify key markers of plasma cells and explore their role in high-grade serous ovarian cancer (HGSOC).
Methods: We utilized single-cell sequencing data from the Gene Expression Omnibus (GEO) database to identify key immune cell types within HGSOC tissues and to extract related markers via the Seurat package.

Background: Neuropilin-1 (NRP1) is a transmembrane protein involved in surface receptor complexes for a variety of extracellular signals. NRP1 expression in human cancers is associated with prominent angiogenesis and advanced progression stage. However, the molecular mechanisms underlying NRP1 activity in the tumor microenvironment remain unclear.

The fibroblast growth factor (FGF) family comprises 15 paracrine-acting and 3 endocrine-acting polypeptides, which govern a multitude of processes in human development, metabolism and tissue homeostasis. Therapeutic endocrine FGFs have recently advanced in clinical trials, with FGF19 and FGF21-based therapies on the cusp of approval for the treatment of primary sclerosing cholangitis and metabolic syndrome-associated steatohepatitis, respectively. By contrast, while paracrine FGFs were once thought to be promising drug candidates for wound healing, burns, tissue repair and ischaemic ailments based on their potent mitogenic and angiogenic properties, repeated failures in clinical trials have led to the widespread perception that the development of paracrine FGF-based drugs is not feasible.

Transforming growth factor-beta (TGF-β), displaying a dual role in immunosuppression and pathogenesis, has emerged as a key regulator of anti-leishmanial immune responses. In Leishmania infections, TGF-β drives immune deviation by enhancing regulatory T-cell (T-reg) differentiation and inhibiting macrophage activation, suppressing critical antiparasitic responses. This cytokine simultaneously promotes fibroblast proliferation, extracellular matrix production, and fibrosis in infected tissues, which aids in wound healing but impedes immune cell infiltration, particularly in visceral leishmaniasis, where splenic disorganization and compromised immune access are notable.

Background: Keloid is a benign skin tumor that result from abnormal wound healing and excessive collagen deposition. The pathogenesis is believed to be linked to genetic predisposition and immune imbalance, although the precise mechanisms remain poorly understood. Current therapeutic approaches may not consistently yield satisfactory outcomes and are often accompanied by potential side effects and risks.
