AI Article Synopsis
- Anemia is prevalent in lung cancer patients, and hemoglobin levels at diagnosis could indicate prognosis.
- A study of 421 lung cancer patients revealed that 52.2% had anemia, with low hemoglobin levels linked to a 41% lower survival rate.
- Monitoring hemoglobin levels may improve prognosis and treatment strategies for lung cancer patients.
Article Abstract
Background And Objective: Anemia is commonly observed in lung cancer (LC). Hemoglobin levels at the time of diagnosis could be considered a prognostic indicator in patients with LC. The aim of this trial was to analyze hemoglobin levels at the time of diagnosis as a prognostic factor in patients with LC.
Patients And Method: We retrospectively examined all patients with LC (cytologically or histologically confirmed) diagnosed in our health area for a period of 3 years. Correlation between hemoglobin levels and survival was assessed. All patients were divided into 2 groups: patients with low hemoglobin levels (lower than percentile 25 of the distribution), and patients who exceeded that figure. By means of Cox's regression, the influence of hemoglobin levels in survival was calculated and adjusted to other factors.
Results: 421 patients were included, 52.2% of them presented anemia at the time of diagnosis. Mean age was 65.8 years and 92.7% were male. The group of patients with hemoglobin levels lower than percentile 25 had a survival rate that was 41% inferior.
Conclusions: Low hemoglobin levels are associated with decreased survival in patients with LC. The evaluation of this parameter could be used for a more accurate prognosis in LC and a better adequacy of therapeutic indications.

Intravenous iron therapy for treating patients with iron deficiency anaemia during the perioperative period of gynecological malignancy.

Anaemia is a common phenomenon in patients with malignant gynecological tumors. The occurrence of anaemia in the perioperative period leads to an increased probability of blood transfusion, increased surgical complications,poor wound healing, prolonged hospitalization, increased medical costs, and increased mortality. Intravenous iron, which is known for its rapid onset and lack of gastrointestinal side effects, has become increasingly prevalent in clinical practice.

However, the relationship between NO bioavailability, dynamic regulation of protein -nitrosylation by trans- and de-nitrosylases, and HFpEF pathophysiology has not been elucidated. Here, we provide novel insights into the delicate interplay between NO bioavailability and protein -nitrosylation in HFpEF.

Introduction: Diabetes is a metabolic disorder of glucose homeostasis that is a significant risk factor for neurodegenerative diseases, such as Alzheimer's disease, as well as mood disorders, which often precede neurodegenerative conditions. We examined the medial habenulainterpeduncular nucleus (MHb-IPN), as this circuit plays crucial roles in mood regulation, has been linked to the development of diabetes after smoking, and is rich in cholinergic neurons, which are affected in other brain areas in Alzheimer's disease.
Methods: This study aimed to investigate the impact of streptozotocin (STZ)-induced hyperglycemia, a type 1 diabetes model, on mitochondrial and lipid homeostasis in 4% paraformaldehyde-fixed sections from the MHb and IPN of C57BL/6 J male mice, using a recently developed automated pipeline for mitochondrial analysis in confocal images.
PLK1 inhibition impairs erythroid differentiation.

Polo-like kinase 1 (PLK1), a key regulator of the G2/M phase in mitosis, is frequently overexpressed in numerous tumors. Although PLK1 inhibitors have emerged as promising therapeutic agents for cancer, their use has been linked to significant anemia in a subset of patients, yet the underlying mechanisms remain poorly understood. In this study, we utilized an human umbilical cord blood-derived CD34 cell-based erythroid differentiation system, alongside a murine model, to investigate the impact of PLK1 inhibitors on erythropoiesis.

This study aims to assess the impact of levocarnitine supplementation on hematological and serum iron profile parameters, comparing the efficacy of oral versus intravenous (IV) administration in these patients.
Materials And Methods: This was a multicenter, randomized controlled trial was conducted on patients undergoing MHD at the hemodialysis unit of our study center in Karachi, Pakistan.
