In addition, preoperative and postoperative sixth-month BMI and laboratory parameters of the patients in Group 1 were compared.

TyG index is positively associated with HOMA-IR in cholelithiasis patients with insulin resistance: Based on a retrospective observational study.

Background/objective: Cholelithiasis is a common disease but pose significant global health and financial burdens. Mechanisms of the disease are associated with insulin resistance (IR), obesity, metabolic syndrome, and type 2 diabetes. Insulin resistance is commonly observed in cholelithiasis patients.

Matching-adjusted indirect comparison (MAIC) results confirmed by head-to-head trials: a case study in psoriasis.

Background: Head-to-head comparisons through randomized controlled trials (RCTs) provide high-quality evidence to inform healthcare decisions. In their absence, indirect comparisons are often performed; however, evidence is limited on how valid matching-adjusted indirect comparison (MAIC)-based comparative efficacy estimates are vs. RCT-based estimates.

Materials and methods The outcomes in 268 patients operated on with the diagnosis of colon cancer between January 2011 and March 2019 were retrospectively analyzed.

Ability of ESWL nomograms to predict stone-free rate in children.

Introduction: We aimed to evaluate whether the pediatric extracorporeal shock wave lithotripsy (ESWL) nomograms can predict stone-free status in children effectively and whether they are applicable to our series. We hypothesize that two current nomograms predicting successful treatment with ESWL in pediatric patients are valid.

Study Design: We evaluated 415 renal units (children <18 years) with eligible data who received ESWL treatment for upper urinary tract stones.

The role of the lactate level in determining the risk rates of small bowel resection in incarcerated hernias.

Background: An incarcerated hernia is a part of the intestine or abdominal tissue that becomes trapped in the sac of a hernia. An increase in morbidity and mortality occurs after intestinal resections from strangulated hernias. This study aims to examine the markers that may be effective in determining the risk of small bowel resection due to incarcerated hernias.

Effect of cultivar and season on the robustness of PLS models for soluble solid content prediction in apricots using FT-NIRS.

FT-NIR models were developed for the non-destructive prediction of soluble solid content (SSC), titratable acidity (TA), firmness and weight of two commercially important apricot cultivars, "Hacıhaliloğlu" and "Kabaaşı" from Turkey. The models constructed for SSC prediction gave good results. We could also establish a model which can be used for rough estimation of the apricot weight.
