Variclose Vein Sealing System appears to be safe and effective in treatment of saphenous vein insufficiency. Further randomized studies with long-term outcomes are required for determining optimal treatment modality in patients with saphenous vein insufficiency.

ObjectiveTo investigate the impact of gender difference in early postoperative outcomes in elderly patients (aged 70 or older) undergoing coronary artery bypass grafting surgery.MethodsBetween October 2009 and December 2013, a total of 223 elderly patients (aged 70 or older) undergoing isolated primary coronary artery bypass grafting surgery were included in this retrospective observational cohort study. Patients were divided into two groups according to their gender. The patients' medical records were collected, their baseline preoperative characteristics, operative data, and postoperative outcomes were retrospectively reviewed, and the effect of gender difference in the early postoperative outcomes was analyzed.ResultsGroup 1 (female patients) and Group 2 (male patients) consisted of 71 and 152 patients, respectively. Mean age of patients was 74.4±3.6 years (range: 70-84 years). The level of EuroSCORE I, the incidence of hypertension and hyperlipidemia were significantly higher in Group 1, while the rate of smoking was significantly higher in Group 2. Mean postoperative intubation time, length of intensive care unit and hospital stay were longer in female patients than in male patients, but these differences were not statistically significant. No statistically significant difference between two groups in terms of the transfusion of blood products was observed. The rates of in-hospital mortality and major postoperative complications were statistically similar between the two groups.ConclusionIn conclusion, the female gender was not associated with worse early postoperative outcomes in elderly patients undergoing coronary artery bypass grafting surgery.

Background: The present study investigated the protective effects of carvacrol (CAR) against testicular toxicity induced by sodium arsenite (SA).Methods and Results: Rats were given SA and/or CAR for 14 days. Semen analyzes showed that CAR increased sperm motility and decreased the percentage of anarmol and dead sperm. It was determined that the oxidative stress induced by SA decreased with the increase of Nrf-2 and HO-1 expressions, SOD, CAT, GPx and GSH levels, and MDA levels decreased after CAR treatment. It was observed that autophagy and in ammation triggered by SA in testicular tissue were alleviated by suppressing the expressions of LC3A, LC3B, MAPK-14, NF-kB, TNF-a, IL-1b, iNOS and COX-2 biomarkers in rats given CAR. CAR treatment protected against apoptosis by suppressing Bax and Caspase-3 expressions and triggering Bcl-2 expression in testicles.Conclusions: As a result, it was seen that CAR could provide protection against SA-induced damage in testicular tissues of rats.

According to this study, obesity does not lead to an increased risk of mortality and other adverse outcomes after CABG surgery. However, obesity may prolong hospital stay and increase the cost of CABG operation.

In this study, the effect of lead acetate (PbAc) and sinapic acid (SNP) administration on oxidative stress, apoptosis, inflammation, sperm quality and histopathology in testicular tissue of rats was tried to be determined. PbAc was administered at a dose of 30 mg/kg/bw for 7 days to induce testicular toxicity in rats. Oral doses of 5 and 10 mg/kg/bw SNP were administered to rats for 7 days after PbAc administration. According to our findings, while PbAc administration increased MDA content in rats, it decreased GPx, SOD, CAT activity and GSH content. NF‐kB, IL‐1β, TNF‐α, and COX‐2, which are among the inflammation parameters that increased due to PbAc, decreased with the administration of SNP. Nrf2, HO‐1, and NQO1 mRNA transcript levels decreased with PbAc, but SNP treatments increased these mRNA levels in a dose‐dependent manner. RAGE and NLRP3 gene expression were upregulated in PbAc treated rats. MAPK14, MAPK15, and JNK relative mRNA levels decreased with SNP treatment in PbAc treated rats. While the levels of apoptosis markers Bax, Caspase‐3, and Apaf‐1 increased in rats treated with PbAc, the level of Bcl‐2 decreased, but SNP inhibited this apoptosis markers. PbAc caused histopathological deterioration in testis tissue and negatively affected spermatogenesis. When the sperm quality was examined, the decrease in sperm motility and spermatozoon density caused by PbAc, and the increase in the ratio of dead and abnormal spermatozoa were inhibited by SNP. As a result, while PbAc increased apoptosis and inflammation by inducing oxidative stress in testicles, SNP treatment inhibited these changes and increased sperm quality.
