Long-term outcomes of corneal transplantation: a review of 8,378 patients.

Purpose: To analyze the outcomes of corneal transplantation procedures over a 13-year period at Farabi Eye Hospital, Tehran, Iran, to identify trends and determinants influencing the frequency and success of primary and re-transplantations.

Methods: Utilizing a comprehensive dataset from the hospital's Hospital Information System, the study reviewed the records of 8,378 patients who underwent corneal transplants between 2009 and 2022. This analysis included demographic information, surgical details, and follow-up data.

Plant and marine-derived natural products: sustainable pathways for future drug discovery and therapeutic development.

Plant- and marine-derived natural products are rich sources of bioactive compounds essential for drug discovery. These compounds contain complex mixtures of metabolites, which collectively contribute to their pharmacological properties. However, challenges arise in the isolation of individual bioactive compounds, owing to their intricate chemistry and low abundance in natural extracts.

A novel technique for external iliac artery reconstruction in renal transplant patients with extensively atherosclerotic lower limb vasculature.

We describe a 54-year-old man with type 2 diabetes mellitus, ischemic myopathy, pulmonary hypertension, and end-stage renal disease who was admitted for heart failure and listed for a dual cardiac-renal transplantation. Extensive calcification in the iliac arteries prevented clamping. Proximal endovascular balloon control of the left iliac artery was achieved using contralateral access; distal control was established by passing a Fogarty catheter distally through an iliac arteriotomy, later used for anastomosis of the cadaveric conduit.

The efficacy and safety of nelarabine in relapsed or refractory T-cell acute lymphoblastic leukemia: a systematic review and meta-analysis.

T-cell Acute Lymphoblastic Leukemia (T-ALL) is a subtype of acute lymphoblastic leukemia characterized by the proliferation of abnormal T-cell precursors. Nelarabine, a purine analog, has been approved as a targeted therapy for patients with refractory or relapsed T-ALL. This study aims to evaluate the efficacy and safety of Nelarabine, either as monotherapy or in combination with other therapies, in treating T-ALL.

Severe heat stroke with multiorgan failure following collapse in a sauna.

Heat stroke is characterised by hyperthermia and acute encephalopathy. We describe a rare case of classical heat stroke secondary to prolonged sauna use with multiorgan sequelae including seizures, liver injury, kidney injury, disseminated intravascular coagulation, rhabdomyolysis and type 2 myocardial infarction. The patient was treated with external cooling, intravenous fluid therapy and blood products, and made a full recovery without need for advanced organ support.
