Oncological and Clinical Impacts of Routine Splenic Flexure Mobilization in Anterior Resection.

Background Splenic flexure mobilization (SFM) is widely regarded as one of the most challenging steps in laparoscopic and robotic colorectal surgery, sparking ongoing debate. Some surgeons routinely advocate for SFM, citing its role in achieving greater left colonic reach, which facilitates a safe, tension-free, and well-vascularized anastomosis while adhering to oncological principles. Conversely, others argue that SFM does not consistently ensure these benefits and may increase the risk of complications, including splenic, bowel, or vascular injuries, as well as unnecessarily prolonging the procedure.

Assessing the catalytic potential of novel halogen substituted carbene NHC (F, Cl, Br, I) catalysts in [3 + 2] cycloaddition reactions: A computational investigation.

This study investigated the catalytic behavior of NHC-X ligands (X = F, Cl, Br, I) in cycloaddition reactions, focusing on both mononuclear and binuclear pathways. Using NCI (noncovalent interaction), RDG (reduced density gradient), ELF (electron localization function), and LOL (localized orbital locus) computational analyses, the electronic interactions and stability of the ligands were examined. The results showed that NHC-Cl exhibited the least steric hindrance and strongest transition state stabilization, making it the most efficient catalyst.

The First Reported Foodborne Botulism Outbreak in Riyadh, Saudi Arabia: Lessons Learned.

Background: Botulism has not been previously reported in the Kingdom of Saudi Arabia. This rare and sometimes fatal foodborne illness is caused by neurotoxins and primarily results from consuming home-canned fruits, vegetables, dairy, and seafood products & it can lead to paralysis.

Objective: The purpose of this study was to evaluate the clinical features of patients who developed botulism in Riyadh in 2024 after consuming mayonnaise from a well-known local chain of restaurants in Riyadh, Saudi Arabia.

Effect of short-term carbapenem restriction on the incidence of non-pseudomonal multi-drug resistant Gram-negative bacilli in an intensive care unit.

We conducted a two-phase retrospective study to investigate the impact of a short-term carbapenem restriction on the incidence of non-pseudomonal multidrug-resistant (MDR) Gram-negative bacilli in our intensive care unit (ICU). The first phase of the study (before carbapenem restriction) was conducted between May and July 2016, and the second phase (implementation of carbapenem restriction) between September and November 2016. The incidence of all non-pseudomonal MDR Gram-negative bacilli (extended-spectrum β-lactamase-producing , carbapenem-resistant and MDR ) decreased significantly after carbapenem restriction.
