Serum cystatin C as an early predictor of acute kidney injury in preterm neonates with respiratory distress syndrome.

Preterm neonates with respiratory distress syndrome (RDS) are at increased risk of acute kidney injury (AKI). Our study aimed at determining whether serum cystatin C (sCysC) on day 3 of life (D3) can early predict AKI in preterm neonates with RDS. This prospective study was conducted on 75 preterm neonates; 50 with RDS and 25 without RDS.

A pilot study on sperm DNA damage in β-thalassemia major: is there a role for antioxidants?

Excess iron deposition in patients with beta thalassemia major (BTM) causes excess free radical formation, damages the hypothalamic pituitary testicular axis and production of sperms with DNA defects. As antioxidants were reported to improve fertility in healthy males; their effectiveness to improve sperm DNA defects in adult males with BTM was studied. Twenty fully pubertal BTM patients were included consecutively, all had semen analysis; 10 were found to be azoospermic, so further analysis for sperms and DNA defects was conducted on the remaining 10 participants.

Association between serum 25 (OH) vitamin D level at birth and respiratory morbidities among preterm neonates.

Objectives: To determine the association between 25-hydroxyvitamin D [25(OH)D] levels on first day of life with respiratory distress syndrome (RDS), need and duration of mechanical ventilation, and subsequent development of bronchopulmonary dysplasia (BPD) among preterm neonates.

Study Design: In this case-control study, serum 25(OH)D was measured on first day of life in 65 preterm neonates <34 weeks: 40 with RDS and 25 without RDS and compared between them. Serum 25(OH)D levels were categorized into normal (above 30 ng/ml), insufficiency (20-30 ng/ml), moderate deficiency (10-20 ng/ml), and severe deficiency (<10 ng/ml).

Resistin and Insulin Resistance: A Link Between Inflammation and Hepatocarcinogenesis.

Background: Hepatocellular carcinoma (HCC) is the sixth most common cancer and the third leading cause of cancer related death overall. The role of insulin resistance in the development of HCC associated with chronic HCV infection has not been established. Resistin is a polypeptide hormone belonging to the adipokine family which could contribute to tumorigenesis and angiogenesis.
