Peri-operative identification and management of patients with unhealthy alcohol intake.

Introduction: This consensus statement gives practical advice for the safe management of patients with harmful alcohol intake undergoing elective and emergency surgery. The wide spectrum of alcohol-related organ dysfunction observed in this cohort of patients may have a profound impact on care, and the additional effects of alcohol withdrawal may further exacerbate postoperative morbidity and mortality.

Methods: A working party was assembled based on clinical and/or academic expertise in the area.

Association between vitamin D status at 3 years and eosinophilic asthma in 6-year-old children with a history of severe bronchiolitis.

The association between early childhood serum 25-hydroxyvitamin D (25(OH)D) and eosinophilic asthma remains unclear. We investigated this association using multicentre prospective data from 584 children with a history of bronchiolitis requiring hospitalisation (high-risk population). Low serum 25(OH)D levels (<20 ng/mL) were associated with increased odds of developing eosinophilic asthma (adjusted OR 2.

Single-Molecule Tracking dataset for histone H3 (hht1) from live and fixed cells of Schizosaccharomyces pombe.

Single-molecule tracking provides direct real-time measurements of protein dynamics in live cells with high spatiotemporal resolution. In the last decade, this method has been adopted by several labs to understand the dynamics of DNA replication, transcription, telomerase, chromatin remodeling, etc. in a variety of model systems (bacteria, yeast S.

Role of ATP-dependent chromatin remodelers in meiosis.

In eukaryotic cells, DNA is wrapped around histone octamers to compact the genome. Although such compaction is required for the precise segregation of the genome during cell division, it restricts the DNA-protein interactions essential for several cellular processes. During meiosis, a specialized cell division process that produces gametes, several DNA-protein interactions are crucial for assembling meiosis-specific chromosome structures, meiotic recombination, chromosome segregation, and transcriptional regulation.

Ascitic Shear Stress Activates GPCRs and Downregulates Mucin 15 to Promote OvarianCancer Malignancy.

The accumulation of ascites in patients with ovarian cancer increases their risk of transcoelomic metastasis. Although common routes of peritoneal dissemination are known to follow distinct paths of circulating ascites, the mechanisms that initiate these currents and subsequent fluid shear stresses are not well understood. Here, we developed a patient-based, boundary-driven computational fluid dynamics model to predict an upper range of fluid shear stress generated by the accumulation of ascites.

Preadmission Penicillin Allergy Evaluation Before Hematopoietic Stem Cell Transplantation Optimizes Febrile Neutropenia Treatment and Inpatient Resource Utilization.

Febrile neutropenia is a common complication of conditioning chemotherapy for hematopoietic stem cell transplant (HSCT), but a major barrier for optimal treatment of febrile neutropenia is historical penicillin allergies. Our group recently published a development of a clinical pipeline for delabeling penicillin allergies in adult patients planned to undergo hematopoietic stem cell transplant (HSCT). In this retrospective cohort study, we followed patients to evaluate their outcomes during inpatient admission for HSCT.

ANTIMICROBIAL WOUND DRESSINGS FOR FULL-THICKNESS INFECTED BURN WOUNDS.

Infection of wounds delays healing, increases treatment costs, and leads to major complications. Current methods to manage such infections include antibiotic ointments and antimicrobial wound dressings, both of which have significant drawbacks, including frequent reapplication and contribution to antimicrobial resistance. In this work, we developed wound dressings fabricated with a medical-grade polyurethane coating composed of natural plant secondary metabolites, cinnamaldehyde, and alpha-terpineol.

Manganese catalysed dehydrocoupling of silanes and siloxanes with ammonia to prepare oligosilazanes and polysiloxazanes.

The halogen-free synthesis of oligosilazanes has been observed upon dehydrocoupling silanes with ammonia at 25 °C using [(BDI)Mn(μ-H)]. Extending this methodology to polymethylhydrosiloxanes afforded thermally robust polysiloxazane solids, and the dehydrocoupling of 1,3,5,7-tetramethylcyclotetrasiloxane with ammonia afforded a polysiloxazane having a weight-average molecular weight of 4300 g mol. A representative oligosilazane has been applied to a copper surface and found to afford a 20 μm thick coating that resists corrosion after 24 h under water.

Non-selective beta-blocker is associated with reduced mortality in critically ill patients with cirrhosis: A real-world study.

Background: Apart from direct portal pressure reduction, non-selective beta-blockers (NSBB) modulate inflammatory response, which could be beneficial in patients with acute decompensation (AD). We therefore aimed to evaluate the effect of NSBB on 28-day mortality and markers of systemic inflammation in a propensity score-matched (PSM) cohort of AD patients requiring intensive care unit (ICU) admission.

Methods: Patients were recruited from registry of AD patients requiring ICU admission.

One flask cascade approach to a complex pyrano[2,3-]pyrazole-pyrazolone hybrid heterocyclic system and its initiatory neurobiological profiling.

A one-pot multicomponent approach towards a hybrid heterocyclic pyrano[2,3-]pyrazole-pyrazolone framework involving tandem Knoevenagel condensation, sequential intermolecular 1,6-Michael addition, and 6- cyclization between diynones and pyrazolones, mediated by DBU, has been discovered. This process embodies several green and sustainable chemistry features. Preliminary bioactivity profiling of the new chemical entities indicates neuroprotective and AChE inhibitory activities.

FDA approval summary: fam-trastuzumab deruxtecan-nxki for unresectable or metastatic non-small cell lung cancer with activating HER2 mutations.

On August 11, 2022, FDA granted accelerated approval to fam-trastuzumab deruxtecan-nxki (DS-8201a, T-DXd, ENHERTU, Daiichi Sankyo) for adult patients with unresectable or metastatic non-small cell lung cancer (NSCLC) whose tumors have activating human epidermal growth factor receptor 2 (HER2) mutations, as detected by an FDA-approved test, and who have received a prior systemic therapy. The approval was based on a prespecified interim analysis of DESTINY-Lung02 (Study U206), a multi-center, randomized, dose-optimization trial in patients with NSCLC harboring activating HER2-mutations. At the approved dose of 5.

Proteostasis in neurodegenerative diseases.

Proteostasis is essential for normal function of proteins and vital for cellular health and survival. Proteostasis encompasses all stages in the "life" of a protein, that is, from translation to functional performance and, ultimately, to degradation. Proteins need native conformations for function and in the presence of multiple types of stress, their misfolding and aggregation can occur.

Natural products from the human microbiome: an emergent frontier in organic synthesis and drug discovery.

Often referred to as the "second genome", the human microbiome is at the epicenter of complex inter-habitat biochemical networks like the "gut-brain axis", which has emerged as a significant determinant of cognition, overall health and well-being, as well as resistance to antibiotics and susceptibility to diseases. As part of a broader understanding of the nexus between the human microbiome, diseases and microbial interactions, whether encoded secondary metabolites (natural products) play crucial signalling roles has been the subject of intense scrutiny in the recent past. A major focus of these activities involves harvesting the genomic potential of the human microbiome bioinformatics guided genome mining and culturomics.

Synthetic Approach toward Diverse Oxa-Cages via Olefin Metathesis.

This article demonstrates a late-stage modification of the cage propellanes that are transformed into intricate oxa-cycles via ring-rearrangement metathesis (RRM) and regioselective ring-closing metathesis (RCM) as crucial steps. In addition, we also report the extended pentacycloundecane (PCUD)-based oxa-cages involving the domino cycloetherification followed by olefin metathesis. These oxa-cages involve a domino sequence in which the PCUD core unit remains intact.
