Prevalence and Prognostic Significance of Malnutrition Risk in Patients With Valvular Heart Disease.

Background: Previous studies on the prevalence and prognosis of nutritional status in valvular heart disease (VHD) were primarily limited to aortic stenosis. The nutritional status of other types of VHDs remained an underexplored area.

Objectives: This study aimed to evaluate the prevalence of malnutrition risk in different types of VHD and investigate the association between malnutrition risk and adverse clinical events.

Narrowing and blue-shifting photoluminescence of carbon dots by enhancing sp-C hybridization using a microreactor.

Effectively narrowing and blue-shifting photoluminescence (PL) of carbon dots (CDs) through enhancing their sp-C hybridization degree by using a microreactor are achieved. The resulting CDs emit ultraviolet (UV) PL centered at 345 nm with a full width at half maximum (FWHM) of 54 nm, with blue-shift of over 100 nm and FWHM narrowed by nearly half in comparison with that of the CDs prepared by using the traditional solvothermal method.

Cardiovascular Risk Factors in Patients with Valvular Heart Disease: A Nationwide Observational Cohort Study.

Purpose: Conventional cardiovascular risk factors may contribute to the development of valvular heart disease (VHD). The present study sought to investigate the distribution of conventional modifiable cardiovascular risk factors (smoking, hypertension, hyperlipidemia, and diabetes) in various VHDs, the impact of risk factors on outcomes, and the prognostic indicators in patients with distinct burdens of risk factors.

Patients And Methods: The study included 11862 patients with moderate or greater VHD.

Disulfiram-loaded nanovesicles hydrogel promotes healing of diabetic wound.

Background: Traditional methods for treating diabetic wounds are limited in effectiveness because of their long healing times, the risk of immune rejection, and susceptibility to infection. Suppressing neutrophil extracellular traps (NETs) is an effective strategy for reducing persistent inflammation in diabetic wounds. Although disulfiram (DSF) can inhibit the significant increase of NETs in diabetic wounds, oral DSF suffers from rapid and harmful metabolism in the liver.

A systematic, updated review of Xuezhikang, a domestically developed lipid-lowering drug, in the application of cardiovascular diseases.

A large proportion of people with dyslipidaemia have poorly controlled lipid levels, emphasizing the need for alternative lipid-lowering treatments that are both effective and safe. Xuezhikang, a red yeast rice (RYR) extract, containing 13 kinds of monacolins and other bioactive components, emerges as one such promising option.

A Photo-Assisted Zinc-Air Battery with MoS/Oxygen Vacancies Rich TiO Heterojunction Photocathode.

Converting solar energy into electrochemical energy is a sustainable strategy, but the design of photo-assisted zinc-air battery (ZAB) with efficient utilization of sunlight faces huge challenges. Herein, a photo-assisted ZAB of a three-electrode system using MoS/oxygen vacancies-rich TiO heterojunction as charge cathode and Fe, N-doped carbon matrix (FeNC) as discharge cathode is constructed, where MoS is chosen as solar light-responsive catalytic material and TiO acts as electron transport layer and hole blocking layer, arising from a train of thought for efficient charging under sunlight irradiation and light-independent discharging. The introduction of oxygen vacancies in TiO facilitates the temporary trapping of carriers and triggers rapid carrier transfer at the interface of the heterojunction, which hinders the recombination of photogenerated holes, thereby facilitating their further participation in the oxygen evolution reaction.

Impact of metabolic abnormalities on the association between normal-range urinary albumin-to-creatinine ratio and cardiovascular mortality: evidence from the NHANES 1999-2018.

Background: The urinary albumin to creatinine ratio (UACR) is associated with adverse cardiovascular outcomes, even when within the normal range. However, the potential modification of this effect by metabolic abnormalities remains unclear. This study explored whether metabolic abnormalities modify the association between normal-range UACR and cardiovascular mortality.

TREM2 aggravates sepsis by inhibiting fatty acid oxidation via the SHP1/BTK axis.

Impaired fatty acid oxidation (FAO) and the therapeutic benefits of FAO restoration have been revealed in sepsis. However, the regulatory factors contributing to FAO dysfunction during sepsis remain inadequately clarified. In this study, we identified a subset of lipid-associated macrophages characterized by high expression of trigger receptor expressed on myeloid cells 2 (TREM2) and demonstrated that TREM2 acted as a suppressor of FAO to increase the susceptibility to sepsis.

AttriPrompter: Auto-Prompting with Attribute Semantics for Zero-shot Nuclei Detection via Visual-Language Pre-trained Models.

Large-scale visual-language pre-trained models (VLPMs) have demonstrated exceptional performance in downstream object detection through text prompts for natural scenes. However, their application to zero-shot nuclei detection on histopathology images remains relatively unexplored, mainly due to the significant gap between the characteristics of medical images and the weboriginated text-image pairs used for pre-training. This paper aims to investigate the potential of the object-level VLPM, Grounded Language-Image Pre-training (GLIP), for zero-shot nuclei detection.

Associations of metabolic syndrome and its components with sarcopenia, and the mediating role of insulin resistance: Findings from NHANES database.

Background: To investigate the association between metabolic syndrome (MetS) and its components with sarcopenia, and to explore the extent to which insulin resistance (IR) mediates this association, using data from the National Health and Nutrition Examination Survey (NHANES).

Methods: We analyzed cross-sectional data from 15,779 adults in the NHANES from 1999 to 2006 and 2011-2018. Multivariable logistic regression models were used to determine the odds ratios (ORs) between MetS, its components, the number of MetS components, and sarcopenia.

The role of residual inflammatory risk and LDL cholesterol in patients with in-stent restenosis undergoing percutaneous coronary intervention.

Background: To evaluate the relationships between residual inflammatory risk [assessed by high-sensitivity C-reactive protein (hsCRP)], residual cholesterol risk [assessed by low-density lipoprotein cholesterol (LDL-C)] and clinical outcomes among patients who underwent percutaneous coronary intervention (PCI) for in-stent restenosis (ISR) lesions.

Methods: Between January 2017 and December 2018, a total of 2079 patients who underwent PCI for ISR were consecutively enrolled. The primary outcome was the rate of major adverse cardiac events (MACE), defined as a composite endpoint of all-cause death, spontaneous myocardial infarction (MI), or repeat revascularization.

Oxygen-doped Carbon Nitrides with Visible Room-temperature Phosphorescence and Invisible Thermal-Stimuli-Responsive Ultraviolet Delayed Fluorescence for Security Applications.

Multi-mode emissive materials with stimuli-responsive producing invisible signals are very attractive for advanced security applications, but development of such materials remains highly challenging. In this work, oxygen-doped carbon nitrides (O-CNs) are prepared via microwave-assisted heating of urea, which exhibit ultraviolet (UV) solid-state fluorescence (SSFL), visible room temperature phosphorescence (RTP) and thermal-stimuli production of invisible UV delayed fluorescence (DF) properties. Further studies confirmed that the SSFL and RTP could be attributed to the introduction of oxygen functional group (e.

HSP70 contributes to pathogenesis of fulminant hepatitis induced by coronavirus.

Fulminant viral hepatitis (FH) represents a significant clinical challenge, with its pathogenesis not yet fully elucidated. Heat shock protein (HSP)70, a molecular chaperone protein with a broad range of cytoprotective functions, is upregulated in response to stress. However, the role of HSP70 in FH remains to be investigated.

Galectin-3 induces pathogenic immunosuppressive macrophages through interaction with TREM2 in lung cancer.

Background: High infiltration of tumor-associated macrophages (TAMs) is associated with tumor promotion and immunosuppression. The triggering receptor expressed on myeloid cells 2 (TREM2) is emerged as a key immunosuppressive regulator for TAMs, however, how TREM2-expressing TAMs are recruited and what ligands TREM2 interacts with to mediate immunosuppression is unknown.

Methods: Flow cytometry and single-cell RNA sequencing were used to analyze TREM2 expression.

LncRNA-mRNA co-expression analysis reveals aquaporin-9-promoted neutrophil extracellular trap formation and inflammatory activation in sepsis.

Sepsis is a life-threatening condition caused by an excessive inflammatory response to an infection. However, the precise regulatory mechanism of sepsis remains unclear. Using a strand-specific RNA-sequencing, we identified 115 hub differentially expressed long noncoding RNAs (lncRNAs) and 443 mRNAs in septic patients, primarily participated in crucial pathways including neutrophil extracellular trap (NET) formation and toll-like receptor signaling.

Background And Objectives: The relationship between physical frailty, age-related conditions, and the incidence of degenerative valvular heart disease (VHD) remains unclear. This study aimed to investigate the potential association between physical frailty and the development of degenerative VHD.

Research Design And Methods: Participants from the UK Biobank who were initially free of VHD and heart failure were categorized into 3 groups based on the frailty phenotype: non-frailty, pre-frailty, and frailty.

Artificial Intelligence in the Screening, Diagnosis, and Management of Aortic Stenosis.

The integration of artificial intelligence (AI) into clinical management of aortic stenosis (AS) has redefined our approach to the assessment and management of this heterogenous valvular heart disease (VHD). While the large-scale early detection of valvular conditions is limited by socioeconomic constraints, AI offers a cost-effective alternative solution for screening by utilizing conventional tools, including electrocardiograms and community-level auscultations, thereby facilitating early detection, prevention, and treatment of AS. Furthermore, AI sheds light on the varied nature of AS, once considered a uniform condition, allowing for more nuanced, data-driven risk assessments and treatment plans.
