The aim of this study is to evaluate the results of photorefractive keratectomy (PRK) in the management of postoperative hyperopia and astigmatism in patients with history of radial keratotomy (RK). ⋯ PRK seems to bring favorable outcome and safety profile in the management of post-RK hyperopia and astigmatism. It is crucial for practitioners to warn their patients about the fact that they may still have progressive refractive instability regardless of their choice on the laser method of vision correction.

The normal prostate-specific antigen (PSA) level in patients with urethral catheterization is a controversy. We designed this study to investigate the effect of nontraumatic urethral catheterization without urinary retention on serum PSA. ⋯ Nontraumatic urethral catheterization has very little effect on PSA level and in patients with urethral catheter routine evaluation of PSA rising should be considered.

In this study, we aimed to determine comprehensive maternal characteristics associated with birth weight using Bayesian modeling. ⋯ Higher maternal macro- and micro-nutrient intake during pregnancy was associated with a lower risk of delivering low birth weight infants. These findings support recommendations to expand intake of nutrients during pregnancy to high level.

Stroke as a devastating condition is a major cause of death worldwide. It is accountable for long-term disability with high personal and social cost in adults. Alpha-lipoic acid (ALA) is an eight-carbon, sulfur-containing compound with antioxidant properties which reduces body weight, changes other anthropometric indices, and regulates food intake by suppressing appetite and increasing metabolism This study was designed to evaluate the possible effects of ALA supplementation on anthropometric indices and dietary intake in patients with stroke. ⋯ Results of this trial indicated that 12-week supplementation with 600 mg ALA can decrease waist circumference and food intake (energy, carbohydrate, protein, and fat) in patients with stroke.

Matrix metalloproteinase 9 (MMP9) -1562C>T (rs3918242) polymorphism has been proposed as a risk factor for coronary artery disease (CAD) with conflicting results. The aim of the present study was to investigate the association of -1562C>T genetic polymorphism, gene expression and circulating levels of MMP9 with CAD risk in an Iranian subpopulation in in Zanjan City. ⋯ Our study demonstrated that circulating levels of MMP9 but not -1562C>T polymorphism of MMP9 gene may be a risk factor for development and severity of CAD in an Iranian subpopulation in Zanjan.
