In this study, we compared the operative time for unilateral inguinal hernia repair in children performed with either an open approach (OA) or the Percutaneous Internal Ring Suturing (PIRS) method. It was a retrospective chart review of all patients ages 0 to 18 who underwent unilateral inguinal hernia repair in the Department of Pediatric Surgery, Urology and Traumatology of the Regional Hospital in Kielce between January 2011 and December 2018. Patients with bilateral hernias or additional problems were excluded. Of 878 patients qualified for the study, 701 were in the OA group and 177 in the PIRS group. Overall, the time needed to complete the procedure was significantly longer for the OA method. The operative time was longer if the hernia was left-sided (p = 0.024). Analysis by gender showed that operative time was generally longer in males. For both genders, surgery was shorter if the PIRS method was used. For males in the PIRS group the operative time was affected by the location of the hernia, and it was longer for a left-sided hernia. The take-home message is that the PIRS procedure is faster than the OA for inguinal hernia repair in children and it might be considered as a preferred method, especially in females.

Background: Colorectal cancer (CRC), the most common malignancy of the gastrointestinal tract, is the second leading cause of cancer-related deaths worldwide. In this context, investigating low-penetrance gene variants associated with the increased risk of CRC represents a novel and crucial approach to enhancing prevention strategies and clinical surveillance. By focusing on these genetic variants, there is potential for more accurate prediction of individual CRC risk, which could contribute to the refinement of current screening and prophylactic programs. The aim of this case–control study was to explore the association between SIRT1 polymorphisms and CRC risk. Methods: We analyzed three SNPs—rs12778366 (T/C), rs3758391 (C/T), and rs7895833 (A/G)—in the promoter region of the SIRT1 gene, which may influence SIRT1 expression and thus play a role in cancer development. Our study included 200 patients with colorectal adenocarcinoma and 115 controls. Genomic DNA was extracted from blood samples, and SIRT1 SNP analysis was performed using the qPCR method and endpoint genotyping. Results: Univariate regression analysis revealed a slightly increased risk of developing CRC in individuals with minor alleles of the analyzed polymorphisms; however, the observed differences were not statistically significant. Conclusions: Although our findings did not reveal statistically significant differences in SIRT1 gene polymorphism frequencies between the CRC group and the control group, we observed a tendency that suggests further investigation in larger cohorts is warranted. This research underscores the importance of understanding low-penetrance genetic factors in CRC, highlighting their potential to inform more personalized and effective prevention strategies.

Background/Objectives: Pediatric cardiac arrest poses considerable obstacles, with survival rates markedly inferior to those of adults. Effective chest compressions are essential for enhancing outcomes; nevertheless, the ideal rescuer attitude is still ambiguous. This study sought to compare the efficacy of lateral (LAT) and over-the-head (OTH) chest compression techniques in pediatric cardiopulmonary resuscitation (CPR) and to ascertain whether OTH presents a viable alternative to the conventional LAT method by assessing compression quality, rescuer fatigue, and ergonomics. Methods: A randomized crossover simulation study was conducted in a high-fidelity medical simulation facility. Thirty-five medical students executed 2 min cycles of chest compressions with both LAT and OTH techniques, interspersed with a 15 min rest period between sessions. Results: OTH showed a tendency for enhanced overall performance (72.94 vs. 64.46; p = 0.08), while the differences lacked statistical significance. The compression rate was somewhat elevated with OTH (116.94 compared to 114.57; p = 0.31). We assessed LAT as somewhat less challenging (4.37 vs. 3.91; p = 0.17) and found less fatigue (4.83 vs. 4.40; p = 0.24). Male rescuers and individuals with elevated BMI attained larger compression depths. Age was negatively connected with the ease and efficiency of compressions. Conclusions: Although no statistically significant differences were detected, OTH demonstrated potential for enhanced performance. The anthropometrics of rescuers affected the quality of CPR, highlighting the necessity for tailored training methods. Future investigations should examine the long-term viability of OTH in clinical and pre-hospital environments.
