Introduction: Transition of care from hospital to primary care has been recognised globally as a high-risk scenario for older patients' safety by the WHO. Indeed, sub-optimal care transitions are associated with increased mortality, morbidity and adverse events.Improving communication through timely and accurate clinical information transfer has been identified as a key component of optimal care transitions.

Article Synopsis
  • The study aimed to find if lower contrast enhancement on postoperative MRI is linked to a higher chance of complications in patients undergoing nasoseptal flap (NSF) reconstruction after surgery.
  • It involved a review of patients who had an endoscopic endonasal approach with NSF reconstruction, assessing their MRIs for enhancement scores that indicate how well the flap is healing.
  • Results showed that patients with lower enhancement scores had significantly higher odds of complications, suggesting that MRI enhancement levels could help surgeons predict patient outcomes more effectively.

Introduction: Current guidelines for treatment for locally advanced pancreatic cancer recommend chemotherapy ± radiation, or radiation alone when multimodal therapy is contraindicated. In a subset of patients, guideline-recommended treatment (GRT) achieves sufficient response to qualify for potentially curative resection. This study evaluated trends in treatment utilization and aimed to identify barriers to GRT.

Rationale And Objective: Avoidance of opioid withdrawal plays a key role in human opioid addiction. Here, we present a procedure for studying operant negative reinforcement in rats that was inspired by primate procedures where opioid-dependent subjects lever-press to prevent naloxone infusions.

Methods: In Experiment 1, we trained rats (n = 30, 15 females) to lever-press to escape and then avoid mild footshocks (0.

Broad-spectrum RAS inhibition has the potential to benefit roughly a quarter of human patients with cancer whose tumours are driven by RAS mutations. RMC-7977 is a highly selective inhibitor of the active GTP-bound forms of KRAS, HRAS and NRAS, with affinity for both mutant and wild-type variants. More than 90% of cases of human pancreatic ductal adenocarcinoma (PDAC) are driven by activating mutations in KRAS.

Article Synopsis
  • Scientists are looking for better ways to detect pancreatic cancer early so it can be treated more effectively.
  • They studied blood samples from 426 patients to find different markers that could indicate pancreatic cancer compared to other conditions.
  • Results showed that a mix of certain protein markers and DNA changes in the blood can help identify early-stage pancreatic cancer better than just using one marker alone.

Article Synopsis
  • Scientists found that blocking RAS, a gene that can cause cancer when mutated, might help about 25% of cancer patients.
  • They tested a drug called RMC-7977 on various cancer models, especially pancreatic cancer, and saw it stopped tumors from growing without harming normal tissue.
  • The drug caused cancer cells to die off, but normal cells only slowed down a bit, showing it could be a good option for treating pancreatic cancer.

Article Synopsis
  • Emerging research suggests that gut bacteria (microbiome) may play a role in pancreatic cancer (PaCa) development.
  • The study analyzed blood samples from 172 individuals diagnosed with PaCa and 863 matched control samples to explore the relationship between microbial-related metabolites and PaCa risk.
  • A panel of microbial and non-microbial metabolites was created to enhance risk prediction for PaCa, identifying individuals at high risk who could benefit from closer monitoring and potential preventive strategies.

Background: The COVID-19 pandemic caused a wave of acute respiratory distress syndrome (ARDS) with a high in-hospital mortality, especially in patients requiring invasive mechanical ventilation. Wharton Jelly-derived Mesenchymal Stromal Cells (WJ-MSCs) may counteract the pulmonary damage induced by the SARS-CoV-2 infection through pro-angiogenic effects, lung epithelial cell protection, and immunomodulation.

Methods: In this randomized, double-blind, placebo-controlled phase 2a trial, adult patients receiving invasive mechanical ventilation for SARS-CoV-2 induced moderate or severe ARDS were assigned to receive 1 intravenous infusion of 1 × 10 WJ-MSCs/kg or placebo within 48 h of invasive ventilation followed by 2 infusions of 0.

The fungal cell wall and secreted exopolysaccharides play an important role in the interactions between fungi and their environment. Despite their central role in fungal biology, ecology, and host-pathogen interactions, the composition of these polymers and their synthetic pathways are not well understood. The protocols presented in this article describe an approach to isolate fungal cell wall polysaccharides and to identify and quantify the monosaccharide composition of these polymers by gas chromatography-mass spectrometry (GC-MS).

Historically, the management of pancreatic cystic neoplasms (PCN) has been operative. Early intervention for premalignant lesions, including intraductal papillary mucinous neoplasms (IPMN) and mucinous cystic neoplasms (MCN), offers an opportunity to prevent pancreatic cancer-with potential decrement to patients' short-term and long-term health. The operations performed have remained fundamentally the same, with most patients undergoing pancreatoduodenectomy or distal pancreatectomy using oncologic principles.

Purpose: The Enhanced Recovery After Surgery (ERAS) protocol is a multimodal perioperative care bundle aimed to improve pancreatic surgery outcomes. This work evaluates whether a Whipple ERAS protocol can be safely implemented at a quaternary care center. We also aimed to assess if race and socioeconomic factors are associated with disparities in outcomes in patients undergoing a Whipple ERAS protocol.

G protein-coupled receptors (GPCRs) promote the expression of immediate early genes required for learning and memory. Here, we showed that β-adrenergic receptor (βAR) stimulation induced the nuclear export of phosphodiesterase 4D5 (PDE4D5), an enzyme that degrades the second messenger cAMP, to enable memory consolidation. We demonstrated that the endocytosis of βAR phosphorylated by GPCR kinases (GRKs) mediated arrestin3-dependent nuclear export of PDE4D5, which was critical for promoting nuclear cAMP signaling and gene expression in hippocampal neurons for memory consolidation.

Background: Healthcare curricula need summative assessments relevant to and representative of clinical situations to best select and train learners. Simulation provides multiple benefits with a growing literature base proving its utility for training in a formative context. Advancing to the next step, "the use of simulation for summative assessment" requires rigorous and evidence-based development because any summative assessment is high stakes for participants, trainers, and programs.
