Evolving Clinical Features of Diabetic Ketoacidosis: The Impact of SGLT2 Inhibitors.

Pharmaceuticals (Basel)

November 2024

Department of Endocrinology and Metabolism, Faculty of Medicine, Recep Tayyip Erdogan University, Rize 53100, Türkiye.

: The antidiabetic effect of SGLT2 inhibitors (SGLT2-is) is based on their ability to increase glucose excretion through urine by inhibiting the kidney-resident SGLT2 protein. Euglycemic diabetic ketoacidosis (EuDKA) is an uncommon but potentially life-threatening adverse effect of these medications, which are notable for their antidiabetic, cardiovascular, and renal protective properties. This study aimed to clarify the impact of SGLT2-is on demographic, clinical, and biochemical characteristics in patients with DKA.

Int J Mol Sci

November 2024

Department of Medical Biology, Faculty of Medicine, Recep Tayyip Erdogan University, Rize 53100, Turkey.

Article Synopsis
  • * The study explores how the Hedgehog signalling pathway affects trastuzumab resistance in HER2-positive breast cancer, revealing that resistant cell lines show increased Hedgehog activity and stemness markers.
  • * Treatment with the Hedgehog inhibitor GANT61 combined with trastuzumab significantly lowers stemness marker expression, indicating that targeting Hedgehog signalling could help overcome resistance and improve treatment outcomes.

Background: This cross-sectional study aims to investigate the retino-choroidal degenerative effects of periodontitis, metabolic syndrome (Mets), and the combination of these diseases using optical coherence tomography (OCT) measurements.

Methods: Ninety-two patients selected according to inclusion criteria were divided into four groups: systemically and periodontally healthy (control), systemically healthy periodontitis (PD), periodontally healthy metabolic syndrome (MetS), and periodontitis and metabolic syndrome combined (PD-MetS). The systemic inflammatory-oxidative effects of periodontitis and MetS were biochemically evaluated using the serum TNF-α level, IL-1β/IL-10 ratio, and oxidative stress index (OSI: TOS/TAS).

Adipose tissue represents an organ that is highly dynamic and contributes toward vital survival events such as immune responses, lactation, metabolism fuel, and thermogenesis. Data emerging from recent studies support the notion of adipose tissue being organized into a complex system characterized by a discrete anatomy, elevated physiological plasticity, and specific vascular and nerve supplies. Vasoactive intestinal peptide (VIP), along with its receptors, type 1 (VPAC1) and type 2 (VPAC2), has been implicated in various physiological and pathophysiological processes.

Modern approach to bone comorbidity in prolactinoma.

Pituitary

December 2024

Institute of Endocrine and Metabolic Sciences, San Raffaele Vita-Salute University and IRCCS Hospital, Via Olgettina 60, Milan, 20132, Italy.

Prolactinomas account for more than half of pituitary adenomas, and besides their clinical impact on fertility and gonadal function, they lead to detrimental effects on bone. Patients with prolactinoma are prone to deterioration of bone structure caused not only by prolactin (PRL) induced hypogonadism but also by its direct actions on bone cells and calcium metabolism. However, clinical studies have shown inconsistent evidence regarding whether PRL could have a deleterious effect independently from gonadal insufficiency on skeletal integrity.
