Melanin-Deferoxamine Nanoparticles Targeting Ferroptosis Mitigate Acute Kidney Injury via RONS Scavenging and Iron Ion Chelation.

Rhabdomyolysis (RM)-induced acute kidney injury (AKI) involves the release of large amounts of iron ions from excess myoglobin in the kidneys, which mediates the overproduction of reactive species with the onset of iron overload via the Fenton reaction, thus inducing ferroptosis and leading to renal dysfunction. Unfortunately, there are no effective treatments for AKI other than supportive care. Herein, we developed a multifunctional nanoplatform (MPD) by covalently bonding melanin nanoparticles (MP NPs) to deferoxamine.

Assessment of Relationship between Dietary Factors, Socioeconomic Factor, Behavioral Factor, Physical Measurement and Risk of Migraine: A Univariable and Multivariable Mendelian Randomization Study.

Objective: Although numerous studies have identified associations between socioeconomic, behavioral, dietary, and physical factors and migraine, the causal nature of these relationships has yet to be adequately established.

Methods: We utilized two-sample Mendelian randomization to elucidate the causal associations of 28 distinct traits for socioeconomic factor, behavioral factor, dietary factor and physical measurement with migraine. In the univariable Mendelian randomization analysis, the inverse-variance weighted method served as the primary analytic approach.

First-line treatments for KRAS-mutant non-small cell lung cancer: current state and future perspectives.

mutations are common in non-small cell lung cancer (NSCLC) and are associated with patient prognosis; however, targeting has faced various difficulties. Currently, immunotherapy, chemotherapy, and chemoimmunotherapy play pivotal roles in the first-line treatment of -mutated NSCLC. Here, we summarize the current evidence on first-line therapies and compare the treatment outcomes and biomarkers for different regimens.

Glucocorticoid replacement therapy after retroperitoneal laparoscopic unilateral adrenal adenoma resection in patients with non-cortisol secreting tumors: a retrospective cohort study.

Background: Adrenal Cushing's syndrome is caused by an adrenal tumor that produces hypercortisolism and requires glucocorticoid supplementation following resection of the tumour to prevent adrenal insufficiency. Few studies have examined whether glucocorticoid replacement (GR) therapy is required after retroperitoneal laparoscopic unilateral adrenal adenoma resection in patients with non-cortisol secreting tumors, or whether there is any correlation between preoperative biochemical indicators and postoperative cortisol function. This study sought to investigate which patients with non-cortisol secreting tumors required GR therapy after undergoing retroperitoneal laparoscopic resection of unilateral adrenal cortical adenoma.

Noninvasive early identification of durable clinical benefit from immune checkpoint inhibition: a prospective multicenter study (NCT04566432).

Immune checkpoint inhibitors (ICIs) have changed the treatment landscape for patients with non-small cell lung cancer (NSCLC). In spite of durable responses in some patients, many patients develop early disease progression during the ICI treatment. Thus, early identification of patients with no durable benefit would facilitate the clinical decision for these patients.
