The impact of neoadjuvant therapy in patients with left-sided resectable pancreatic cancer: an international multicenter study.

Purpose: To assess the association between neoadjuvant therapy and overall survival (OS) in patients with left-sided resectable pancreatic cancer (RPC) compared to upfront surgery.

Background: Left-sided pancreatic cancer is associated with worse OS compared to right-sided pancreatic cancer. Although neoadjuvant therapy is currently seen as not effective in patients with RPC, current randomized trials included mostly patients with right-sided RPC.

Protective role of Angiogenin in muscle regeneration in amyotrophic lateral sclerosis: Diagnostic and therapeutic implications.

Amyotrophic lateral sclerosis (ALS) is a fatal neuromuscular disease with no effective treatments, in part caused by variations in progression and the absence of biomarkers. Mice carrying the SOD1G93A transgene with different genetic backgrounds show variable disease rates, reflecting the diversity of patients. While extensive research has been done on the involvement of the central nervous system, the role of skeletal muscle remains underexplored.

Biotissue Curriculum Translates to Performance in the Operating Room for Gastrojejunostomy and Hepaticojejunostomy in Robotic Pancreaticoduodenectomy.

Objective: Robotic simulation training curricula aim to aid surgeons in attaining robotic operating room proficiency, but the crossover success remains to be examined.

Design: A retrospective cohort study grading robotic biotissue training models and intraoperative anastomotic videos. The curriculum included deliberate practice of inanimate drills of a hepaticojejunostomy (HJ) and gastrojejunostomy (GJ).

Effects of ALS-associated 5'tiRNA on the transcriptomic and proteomic profile of primary neurons in vitro.

tRNA-derived stress-induced RNAs (tiRNAs) are a new class of small non-coding RNA that have emerged as important regulators of cellular stress responses. tiRNAs are derived from specific tRNA cleavage by the stress-induced ribonuclease angiogenin (ANG). Loss-of-function mutations in the ANG gene are linked to amyotrophic lateral sclerosis (ALS), and elevated levels of specific tiRNAs were recently identified in ALS patient serum samples.

Video Review Can Measure Surgical Robotic Skill Development in a Resident Robotic Hernia Curriculum: A Retrospective Cohort Study.

Background: Hernia repairs are one of the most common general surgery procedures and an essential part of training for general surgery residents. The widespread incorporation of robotic hernia repairs warrants the development of a procedure-specific robotic curriculum to assist novice surgeons in improving technical skills.

Objective: To evaluate a robotic hernia simulation-based curriculum for general surgery residents using video review.

Rationale and design of a large trial of perioperative ketamine for prevention of chronic post-surgical pain.

Background: Chronic post-surgical pain (CPSP) is recognised as one of the most common and debilitating complications of major surgery. Progression from acute to chronic pain after surgery involves sensitisation of central nervous system pathways with the N-methyl-D-aspartate (NMDA) receptor having a central role. Ketamine is a potent, non-selective NMDA antagonist commonly used for management of acute postoperative pain.

Best Practices for Delivering Neoadjuvant Therapy in Pancreatic Ductal Adenocarcinoma.

Importance: Neoadjuvant therapy (NT) is an increasingly used treatment strategy for patients with localized pancreatic ductal adenocarcinoma (PDAC). Little research has been conducted on cancer care delivery during NT, and the standards for optimal delivery of NT have not been defined.

Objective: To develop consensus best practices for delivering NT to patients with localized PDAC.

Role of Sex and Early Life Stress Experience on Porcine Cardiac and Brain Tissue Expression of the Oxytocin and HS Systems.

Early life stress (ELS) significantly increases the risk of chronic cardiovascular diseases and may cause neuroinflammation. This post hoc study, based on the material available from a previous study showing elevated "serum brain injury markers" in male control animals, examines the effect of sex and/or ELS on the cerebral and cardiac expression of the HS and oxytocin systems. Following approval by the Regional Council of Tübingen, a randomized controlled study was conducted on 12 sexually mature, uncastrated German Large White swine of both sexes.

Metabolic Effects of Sodium Thiosulfate During Resuscitation from Trauma and Hemorrhage in Cigarette-Smoke-Exposed Cystathionine-γ-Lyase Knockout Mice.

Background: Acute and chronic pre-traumatic cigarette smoke exposure increases morbidity and mortality after trauma and hemorrhage. In mice with a genetic deletion of the HS-producing enzyme cystathione-γ-lyase (CSE), providing exogenous HS using sodium thiosulfate (NaSO) improved organ function after chest trauma and hemorrhagic shock. Therefore, we evaluated the effect of NaSO during resuscitation from blunt chest trauma and hemorrhagic shock on CSE mice with pre-traumatic cigarette smoke (CS) exposure.

Extended panel testing in ovarian cancer reveals BRIP1 as the third most important predisposition gene.

Purpose: The prevalence of germline pathogenic variants (PVs) in homologous recombination repair (HRR) and Lynch syndrome (LS) genes in ovarian cancer (OC) is uncertain.

Methods: An observational study reporting the detection rate of germline PVs in HRR and LS genes in all OC cases tested in the North West Genomic Laboratory Hub between September 1996 and May 2024. Effect sizes are reported using odds ratios (ORs) and 95% confidence intervals (95% CI) for unselected cases tested between April 2021 and May 2024 versus 50,703 controls from the Breast Cancer Risk after Diagnostic Gene Sequencing study.

Complexity and Experience Grading to Guide Patient Selection for Minimally-invasive Pancreatoduodenectomy: An ISGPS Consensus.

Objective: The ISGPS aims to develop a universally accepted complexity and experience grading system to guide the safe implementation of robotic and laparoscopic minimally-invasive pancreatoduodenectomy (MIPD).

Background: Despite the perceived advantages of MIPD, its global adoption has been slow due to the inherent complexity of the procedure and challenges to acquiring surgical experience. Its wider adoption must be undertaken with an emphasis towards appropriate patient selection according to adequate surgeon and center experience.

The Effect of Targeted Hyperoxemia on Brain Immunohistochemistry after Long-Term, Resuscitated Porcine Acute Subdural Hematoma and Hemorrhagic Shock.

Epidemiological data suggest that moderate hyperoxemia may be associated with an improved outcome after traumatic brain injury. In a prospective, randomized investigation of long-term, resuscitated acute subdural hematoma plus hemorrhagic shock (ASDH + HS) in 14 adult, human-sized pigs, targeted hyperoxemia (200 < PO < 250 mmHg vs. normoxemia 80 < PO < 120 mmHg) coincided with improved neurological function.

The minimally invasive approach confers improved outcomes in frail cancer patients undergoing hepatectomy: an American College of Surgeons National Surgical Quality Improvement Program analysis.

Background: Morbidity for liver resection has decreased, and frail patients are undergoing surgery. The effect of minimally invasive liver resection (MILR) is unknown. This study aimed to evaluate the effect of MILR on the outcomes in frail patients.

The development of a deep learning model for automated segmentation of the robotic pancreaticojejunostomy.

Background: Minimally invasive surgery provides an unprecedented opportunity to review video for assessing surgical performance. Surgical video analysis is time-consuming and expensive. Deep learning provides an alternative for analysis.

Incumbency and self-uncertainty: when prototypical leaders lose their advantage.

Research on how uncertainty affects the preference for prototypical over non-prototypical leaders has produced mixed results. To understand these discrepancies, two studies explored leader status (prospective versus incumbent) as a potential moderator. Participants reported levels of self-uncertainty (Study 1) or were primed with high versus low self-uncertainty (Study 2) before evaluating a prototypical or non-prototypical leadership candidate who was incumbent or prospective.
