Increased risk of adverse events following the treatment of associated versus elementary acetabular fractures: a matched analysis of short-term complications.

Purpose: This retrospective cohort study aims to compare short-term complication rates between patients receiving open reduction and internal fixation (ORIF) for associated versus elementary acetabular fractures, with a secondary objective of identifying independent risk factors for adverse outcomes.

Methods: The American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) database was queried using current procedural terminology (CPT) codes to identify patients that underwent ORIF for associated acetabular (CPT 27228) or elementary acetabular fractures (CPT 27226, 27227) from 2010 to 2021. Propensity score matching was employed to account for baseline differences and the short-term complication rates were compared between the cohorts.

Neutrophil elastase (NE) has been reported to be a pro-inflammatory stimulus for macrophages. The aim of the present study was to determine the impact of NE exposure on the human macrophage proteome and evaluate its impact on pro-inflammatory signals. Human blood monocytes from healthy volunteers were differentiated to macrophages and then exposed to either 500 nM of NE or control vehicle for 2 h in triplicate.

Association of Lipoprotein(a) With Major Adverse Cardiovascular Events Across hs-CRP: A Systematic Review and Meta-Analysis.

Background: Lipoprotein(a) [Lp(a)] is an independent risk factor for atherosclerotic cardiovascular disease. The relationship between Lp(a) and major adverse cardiovascular events (MACE) in the context of high-sensitivity C-reactive protein (hs-CRP) levels remains controversial due to conflicting results from previous studies.

Objectives: This systematic review and meta-analysis aimed to clarify the association between Lp(a) and risk of MACE across different hs-CRP levels in both primary and secondary prevention settings.

Maintaining prevention focus: the impact of an interdisciplinary taskforce on CAUTI rates during an EMR transition.

We employed an interrupted time series analysis to assess the impact of changing electronic medical records, concurrent with a Catheter-Associated Urinary Tract Infection (CAUTI) Taskforce, on CAUTI rates. We found that rates increased in most ICUs before returning to baseline. These findings suggest that a multi-faceted approach may reduce CAUTI rates.

Such insights are critical for enhancing the efficacy of mycoinsecticides. However, the utilization of these interactions in pest control remains largely unexplored.

oG-miR-6513-5p/BCL2L13 Axis Regulates Mitophagy during Oxidative Stress in the Human Saphenous Vein Endothelial Cells.

Venous graft decay (VGD) occurs in coronary artery bypass grafting (CABG), and ischemia-reperfusion oxidative stress injury during the operation is involved in VGD. To explore the cellular phenotypic changes during this process, a stable oxidative stress model of human saphenous vein endothelial cells (HSVECs) is constructed. Through proteomics and cell experiments, it is found that the expression of BCL2L13 is upregulated during oxidative stress of HSVECs, and BCL2L13 regulated mitophagy through receptor-mediated interaction with LC3 and plays a role in cell protection.

CREB-binding protein/P300 bromodomain inhibition reduces neutrophil accumulation and activates antitumor immunity in triple-negative breast cancer.

Tumor-associated neutrophils (TANs) have been shown to promote immunosuppression and tumor progression, and a high TAN frequency predicts poor prognosis in triple-negative breast cancer (TNBC). Dysregulation of CREB-binding protein (CBP)/P300 function has been observed with multiple cancer types. The bromodomain (BRD) of CBP/P300 has been shown to regulate its activity.

Activating pyruvate kinase improves red blood cell integrity by reducing band 3 tyrosine phosphorylation.

In a phase 1 study (NCT04000165), we established proof of concept for activating pyruvate kinase (PK) in sickle cell disease (SCD) as a viable antisickling therapy. AG-348 (mitapivat), a PK activator, increased adenosine triphosphate (ATP) and decreased 2,3-diphosphoglycerate levels while patients were on treatment, in line with the mechanism of the drug. We noted that the increased hemoglobin (Hb) persisted for 4 weeks after stopping AG-348 until the end of study (EOS).

Association between psychiatric disorders and irritable bowel syndrome: A bidirectional Mendelian randomization study.

Objective: Previous studies have suggested that irritable bowel syndrome (IBS) is strongly associated with psychiatric disorders. However, it is unclear whether this association is causal, concomitant, or accidental. Thus, we performed Mendelian randomization (MR) analysis to evaluate the causal effects of several psychiatric disorders on IBS.

Comparative analysis of metagenomic and targeted next-generation sequencing for pathogens diagnosis in bronchoalveolar lavage fluid specimens.

Background: Although the emerging NGS-based assays, metagenomic next-generation sequencing (mNGS) and targeted next-generation sequencing (tNGS), have been extensively utilized for the identification of pathogens in pulmonary infections, there have been limited studies systematically evaluating differences in the efficacy of mNGS and multiplex PCR-based tNGS in bronchoalveolar lavage fluid (BALF) specimens.

Methods: In this study, 85 suspected infectious BALF specimens were collected. Parallel mNGS and tNGS workflows to each sample were performed; then, we comparatively compared their consistency in detecting pathogens.

Effectiveness and safety of finerenone in diabetic kidney disease patients: a real-world observational study from China.

This study aimed to investigate the effect of finerenone on the renal parameters of the Chinese DKD population in the real-world medical setting for the first time, especially in combination with renin-angiotensin system inhibitors (RASi) and sodium-glucose cotransporter 2 inhibitors (SGLT2i).

Phenotypic Plasticity in Locusts: Trade-Off Between Migration and Reproduction.

Locusts exhibit phenotypic plasticity in response to population density changes, with distinct phenotypes in the solitary and gregarious phases. In the past decade, many studies have revealed the molecular mechanisms underlying phase changes, which include the change of body coloration, pheromones, behavior, flight, fecundity, immunity, and aging. Our understanding of the molecular mechanisms related to these phenotypic differences has expanded in breadth and depth with the decoding of the locust genome, involving transcriptional, post-transcriptional, translational, and epigenetic regulation.

Corynoline protects chronic pancreatitis via binding to PSMA2 and alleviating pancreatic fibrosis.

Background: Pancreatic fibrosis is the main pathological feature of chronic pancreatitis. There is a lack of medications that effectively alleviate or reverse pancreatic fibrosis and thus cure chronic pancreatitis.

Methods: We screened drugs that could alleviate pancreatic fibrosis from 80 traditional Chinese medicine monomers and verified their efficacy and mechanisms.
