Recently, Japan experienced an outbreak of a specific type of iGAS, streptococcal toxic shock syndrome (STSS). The outbreak was reported under the label"flesh-eating bacteria,"emphasizing the pathogenic potential of group A streptococcus (GAS).

Tumour plasticity and tumour microenvironment interactions as potential immunologic targets for pancreatic cancer treatment.

Pancreatic ductal adenocarcinoma (PDAC) is a malignant cancer with a high mortality and limited treatment options. Systemic chemotherapy remains the only approach for improving survival in patients with unresectable locally advanced and/or metastatic disease which comprises most patients. Targeted therapies have so far been disappointing with limited applicability and improvement in overall survival.

Effect of insulin sensitivity, insulin secretion, and beta cell function on the remission of type 2 diabetes: A post hoc analysis of the IDEATE trial.

Aims: To compare the probability of achieving diabetes remission in individuals with different phenotypes of insulin sensitivity, insulin secretion, and beta cell function and further detect the effects of diet, exercise, and lifestyle education intervention on these indexes.

Methods: Three-hundred and one participants who had glycated haemoglobin (HbA1c) data at baseline and after intervention were included for this post hoc analysis. We used the multi-way analysis of variance to assess the differences between the diabetes remission and non-remission groups or between intervention groups in changes of the indexes of insulin sensitivity, insulin secretion, and beta cell function.

Harnessing the tumor microenvironment: targeted cancer therapies through modulation of epithelial-mesenchymal transition.

The tumor microenvironment (TME) is integral to cancer progression, impacting metastasis and treatment response. It consists of diverse cell types, extracellular matrix components, and signaling molecules that interact to promote tumor growth and therapeutic resistance. Elucidating the intricate interactions between cancer cells and the TME is crucial in understanding cancer progression and therapeutic challenges.

Rapid Preparation of Collagen/Red Blood Cell Membrane Tubes for Stenosis-Free Vascular Regeneration.

Extracellular matrix (ECM)-based small-diameter vascular grafts (SDVGs, inner diameter (ID) < 6 mm) hold great promise for clinical applications. However, existing ECM-based SDVGs suffer from limited donor availability, complex purification, high cost, and insufficient mechanical properties. SDVGs with ECM-like structure and function, and good mechanical properties were rapidly prepared by optimizing common materials and preparation, which can improve their clinical prospects.

Revolutionizing Heart Failure Therapy: Harnessing IVT mRNA and Fusion Protein Technology to Prolong rhBNP Half-Life.

Purpose: Recombinant human B-type natriuretic peptide (rhBNP) has been extensively proven to be an effective mean of heart failure (HF) therapy, but its clinical application is limited by its very short half-life. This study aims to combine in vitro transcribed mRNA (IVT mRNA) and fusion protein technology to develop a rhBNP-Fc mRNA drug with long half-life, high efficiency and few side effects to treat HF.

Methods: The rhBNP-Fc fusion mRNA with IgG4-Fc sequence was produced by IVT technology.

Binding mechanism and antagonism of the vesicular acetylcholine transporter VAChT.

The vesicular acetylcholine transporter (VAChT) has a pivotal role in packaging and transporting acetylcholine for exocytotic release, serving as a vital component of cholinergic neurotransmission. Dysregulation of its function can result in neurological disorders. It also serves as a target for developing radiotracers to quantify cholinergic neuron deficits in neurodegenerative conditions.

Genome-wide association study unravels mechanisms of brain glymphatic activity.

Brain glymphatic activity, as indicated by diffusion-tensor imaging analysis along the perivascular space (ALPS) index, is involved in developmental neuropsychiatric and neurodegenerative diseases, but its genetic architecture is poorly understood. Here, we identified 17 unique genome-wide significant loci and 161 candidate genes linked to the ALPS-indexes in a discovery sample of 31,021 individuals from the UK Biobank. Seven loci were replicated in two independent datasets.

Nonlinear exposure-response associations of daytime, nighttime, and day-night compound heatwaves with mortality amid climate change.

Heatwaves are commonly simplified as binary variables in epidemiological studies, limiting the understanding of heatwave-mortality associations. Here we conduct a multi-country study across 28 East Asian cities that employed the Cumulative Excess Heatwave Index (CEHWI), which represents excess heat accumulation during heatwaves, to explore the potentially nonlinear associations of daytime-only, nighttime-only, and day-night compound heatwaves with mortality from 1981 to 2010. Populations exhibited high adaptability to daytime-only and nighttime-only heatwaves, with non-accidental mortality risks increasing only at higher CEHWI levels (75th-90th percentiles).

Neutrophil adhesion to vessel walls impairs pulmonary circulation in COVID-19 pathology.

Microthrombus formation is associated with COVID-19 severity; however, the detailed mechanism remains unclear. In this study, we investigated mouse models with severe pneumonia caused by SARS-CoV-2 infection by using our in vivo two-photon imaging system. In the lungs of SARS-CoV-2-infected mice, increased expression of adhesion molecules in intravascular neutrophils prolonged adhesion time to the vessel wall, resulting in platelet aggregation and impaired lung perfusion.

Expert consensus on sequential surgery after immune-targeted conversion therapy for advanced hepatocellular carcinoma in China.

Hepatocellular carcinoma (HCC) represents a significant global health burden, particularly in the Asia-Pacific region, where it is a leading cause of cancer-related mortality. In China alone, HCC accounts for approximately 367,700 new cases and 316,500 deaths annually; over 50% of patients are diagnosed at an advanced stage, limiting curative treatment options and resulting in poor survival outcomes. Systemic therapies combining immune checkpoint inhibitors (ICIs) with antiangiogenic targeted drugs have shown promise in converting unresectable HCC into resectable cases, potentially transforming clinical outcomes.

Enhancing representation of special populations: An approach to the inclusion of women veterans in VA clinical trials.

The under-recruitment of historically marginalized populations into clinical trials thwarts equitable inclusion of individuals who could benefit from healthcare innovations and limits the generalizability of results. For decades, the Veterans Health Administration (VA) has conducted large clinical trials that impact clinical guidelines for veterans and civilians alike. Within the VA, women are a numeric minority, and recruitment of this population into trials is challenged by gender-specific care structures, distinct demographic characteristics, and mistreatment such as higher rates of military sexual trauma and harassment on VA grounds.
