Epidemiology and outcomes of carbapenem-resistant infections in patients with hematological malignancies from 2014 to 2022.

Background: We aimed to describe the epidemiology, cross-transmission, interventions, and outcomes of carbapenem-resistant (CRKP) infections in the hematological malignancies (HM) department of a hospital in China.

Methods: This prospective study was divided into three stages from 2014 to 2022: Period 1 (from 1 January 2014 to 4 March 2021), Period 2 (from 5 March 2021 to 31 December 2021), and Period 3 (from 1 January 2022 to 31 December 2022), with different measures implemented at each stage to evaluate the rate of new infections. The risk factors, epidemiological characteristics, data from all patients with CRKP, NGS gene sequencing molecular epidemiology analysis, and cross-transmission were described.

The interaction of nutrient uptake with biotic and abiotic stresses in plants.

Plants depend heavily on efficient nutrient uptake and utilization for optimal growth and development. However, plants are constantly subjected to a diverse array of biotic stresses, such as pathogen infections, insect pests, and herbivory, as well as abiotic stress like drought, salinity, extreme temperatures, and nutrient imbalances. These stresses significantly impact the plant's ability to take up nutrient and use it efficiency.

Multi-Scenario Validation and Assessment of a Particulate Matter Sensor Monitor Optimized by Machine Learning Methods.

Objective: The aim was to evaluate and optimize the performance of sensor monitors in measuring PM and PM under typical emission scenarios both indoors and outdoors.

Method: Parallel measurements and comparisons of PM and PM were carried out between sensor monitors and standard instruments in typical indoor (2 months) and outdoor environments (1 year) in Shanghai, respectively. The optimized validation model was determined by comparing six machining learning models, adjusting for meteorological and related factors.

The impact of preoperative biliary drainage on postoperative healthcare-associated infections and clinical outcomes following pancreaticoduodenectomy: a ten-year retrospective analysis.

Background: Pancreaticoduodenectomy (PD) is a complex procedure and easily accompanied by healthcare-associated infections (HAIs). This study aimed to assess the impact of PBD on postoperative infections and clinical outcomes in PD patients.

Methods: The retrospective cohort study were conducted in a tertiary hospital from January 2013 to December 2022.

Epidemiology of healthcare-associated infections and outcomes among open and robotic pancreatoduodenectomy: A retrospective study from 2013 to 2022.

Background And Aim: Healthcare-associated infections (HAIs) after pancreaticoduodenectomy (PD) are one of the common postoperative complications. This study aims to investigate the epidemiology of postoperative HAIs in patients with open pancreaticoduodenectomy (OPD) and robotic pancreaticoduodenectomy (RPD).

Methods: This retrospective cohort study described the trend of HAIs in patients undergoing PD from January 2013 to December 2022 at a tertiary hospital.

Differences in Pathogenicity and Vaccine Resistance Discovered between Two Epidemic Strains of Marek's Disease Virus in China.

Despite highly effective vaccines, Marek's disease (MD) causes great economic loss to the poultry industry annually, largely due to the continuous emergence of new MD virus (MDV) strains. To explore the pathogenic characteristics of newly emerged MDV strains, we selected two strains (AH/1807 and DH/18) with clinically different pathotypes. We studied each strain's infection process and pathogenicity and observed differences in immunosuppression and vaccine resistance.

Efficient CRISPR-Cas13d-Based Antiviral Strategy to Combat SARS-CoV-2.

The current SARS-CoV-2 pandemic forms a major global health burden. Although protective vaccines are available, concerns remain as new virus variants continue to appear. CRISPR-based gene-editing approaches offer an attractive therapeutic strategy as the CRISPR-RNA (crRNA) can be adjusted rapidly to accommodate a new viral genome sequence.

Complete genome analysis reveals evolutionary history and temporal dynamics of Marek's disease virus.

Marek's disease has caused enormous losses in poultry production worldwide. However, the evolutionary process and molecular mechanisms underlying Marek's disease virus (MDV) remain largely unknown. Using complete genomic sequences spanning an unprecedented diversity of MDVs, we explored the evolutionary history and major patterns in viruses sampled from 1964 to 2018.

Emerging natural recombinant Marek's disease virus between vaccine and virulence strains and their pathogenicity.

Marek's disease virus (MDV), an oncogenic virus belonging to the subfamily Alphaherpesvirinae, causes Marek's disease (MD). Vaccines can control MD but cannot block the viral infection; they are considered imperfect vaccines, which carry the risk of recombination. In this study, six natural recombinant MDV strains were isolated from infected chickens in commercial flocks in China.

The Psychological Effect of Forming WeChat Groups Between Medical Staff and Patients With COVID-19.

This study was conducted in order to explore the effect of psychological intervention based on the use of WeChat with coronavirus disease 2019 (COVID-19) patients. A total of 65 patients with COVID-19, from two wards, were divided into an experimental group and a control group with the ward as the basic unit. Communication concerning routine treatment and nursing was established between the medical staff and patients in the experimental group WeChat groups.

Chemodynamic Therapy Combined with Multifunctional Nanomaterials and Their Applications in Tumor Treatment.

During the past few decades, radiotherapy and chemotherapy have been the standard approaches for tumor treatments. However, the potential toxic effect and side effects of both radiotherapy and chemotherapy on the human body still cannot be neglected. Given this, the Fenton reaction has become one of the most effective treatment strategies to combat tumor cells.

Natural co-infection with two virulent wild strains of Marek's disease virus in a commercial layer flock.

Marek's disease (MD) is a highly contagious lymphoproliferative poultry disease caused by the oncogenic herpesvirus, Marek's disease virus (MDV). MDV strains have shown a continued evolution of virulence leading to immune failure, and MD cases continue to occur. Co-infection of virulent MDV strains is an important factor leading to viral evolution and host immune failure.

A high frequency of Gallid herpesvirus-2 co-infection with Reticuloendotheliosis virusis associated with high tumor rates in Chinese chicken farms.

The prevalence of Marek's disease (MD) caused by Gallid herpesvirus-2 (GaHV-2) has been increasing in chickens in China despite universal vaccination. Among the possible reasons for this trend, of Reticuloendotheliosis virus (REV) contamination in vaccines could lead to co-infection and reduce the vaccine efficacy. Here, we report the epidemiological findings of our continuous surveillance of MD, and an examination of the effects of REV and/or GaHV-2 co-infection.

Differential expression of type I interferon mRNA and protein levels induced by virulent Marek's disease virus infection in chickens.

Marek's disease virus (MDV), an α-herpesvirus targeting avian species, causes fatal Marek's disease (MD) in chickens. The host interferon (IFN) responses play a key role in resisting viral infection. However, host IFN responses following MDV infection in the chicken central immune organs (thymus and bursa of Fabricius), which contain numerous MDV target cells, is poorly understood.
