[Predictors of postoperative complications in patients with ventral hernia].

Objective: To evaluate potential predictors of 1-month postoperative complications after primary ventral hernia repair using database of the 1 Clinic of the Samarkand State Medical University.

Material And Methods: A cohort study included 348 patients who underwent ventral hernia surgery in the 1 Clinic of the Samarkand State Medical University between January 1, 2014 and January 1, 2021. We performed logistic regression analysis to identify risk factors of postoperative complications.

Fretting Wear Behavior and Damage Mechanisms of Inconel X-750 Alloy in Dry Contact Condition.

Frictional and fretting wear behaviors of Inconel X-750 alloy against GCr15 steel ball were investigated in dry contact condition with ∼60% air humidity. Fretting tests were run at the high frequency tribosystem SRV 4 in room temperature and ball-on-flat contact configuration were adopted with the relative oscillatory motion of small displacement amplitude (40 m). Sliding regimes, wear volumes, frictional properties, and material damage mechanisms were studied with regard to different normal loading and test durations.

The Discriminative Ability of the Azeri Version of the Strengths and Difficulties Questionnaire in Outpatient Practice.

In this study we examined the validity of the Azeri version of the Strengths and Difficulties Questionnaire (SDQ). The SDQ was administered to the parents of two samples of 4-16-year-old children: the case group was drawn from children presenting to the psychiatric outpatient service (n = 347) and the comparison group from the pediatric outpatient service (n = 267). The total difficulties score and the scores for each subscale were compared between two groups.

Polycyanoacrylate porous material for bone tissue substitution.

A proof of concept study has been conducted for the design of a porous biodegradable material containing nanocapsules and two actives with independent release-bimodal drug-eluting implants. Completely safe synthetic material free from risk of prion and virus contamination was tested in vivo, and a method for controlling the rate of biodegradation of poly-2-cyanoacrylic polymer was developed. Novel perfluorinated 2-cyanoacrylic esters have been applied for the chemical modification of polyethyl-2-cyanoacrlylate copolymers.
