Caution in the use of sedation and endomyocardial biopsy for the management of pediatric acute heart failure caused by endocardial fibroelastosis

Endocardial fibroelastosis(EFE)is commonly considered to be an inflammatory reactive lesion of hyperplasia and deposition of tissue fibers and collagen in the endocardium and/or subendocardium,which is strongly associated with endocardial sclerosis,ventricular remodeling and acute and chronic heart failure,and is one of the important causes for pediatric heart transplantation.Early diagnosis and treatment are the key factors in determining the prognosis of the children.In this paper,we would like to highlight the potential unintended consequences of the use of sedation and biopsy for pediatric acute heart failure caused by EFE and the comprehensive considerations prior to clinical diagnosis.

Study protocol:A cross-sectional study on psychology and behavior investigation of Chinese residents,PBICR

Objective:This study protocol identifies the basic research route and framework of psychological and behavioral surveys among Chinese residents,aims establishing a database through a multicenter,large-sample cross-sectional survey in China to provide strong data support for research development in various fields and a more comprehensive and systematic understanding of the physical and mental health status of the public.Method:The study was conducted from June 20,2022 to August 31,2022,using stratified sampling and quota sampling methods,a total of 148 cities,202 districts and counties,390 townships/towns/sub-districts,and 780 communities/villages(excluding Hong Kong,Macao,and Taiwan)from 23 provinces,5 autonomous regions,and 4 municipalities directly under the central government in China were selected.The questionnaire was distributed one-on-one and face-to-face to the public by trained investigators,and the questionnaire included eight aspects:personal basic information,personal health status,family basic information,social environment in which they were located,psychological level scale,behavioral level scale,other scales,and attitude towards social hot issues.Data analysis will be performed after questionnaire return.Results:Data collection is ongoing.These findings will support physical and mental health research and strategy development in China and even globally,guiding policy-makers and health care organizations to reform their programs to ensure the best interests of residents and their families.

Molecular mechanisms underlying the high mortality of hypervirulent Klebsiella pneumoniae and its effective therapy development

Dear Editor,Klebsiella pneumoniae(Kp)has become the most important bacterial pathogen causing high mortality rates in clinical patients due to the continuous evolution to several important variants such as carbapenem-resistant(CR-Kp),hypervirulent(hvKp)and both CR and hv K.pneumoniae(CR-hvKp).The high mortality caused by clinical hvKp is attributed to the non-response to antibiotic treatment.

Intercontinental spread and clonal expansion of ColRNA1 plasmid-bearing Salmonella Corvallis ST1541 strains:a genomic epidemiological study

Salmonella Corvallis ST1541 has recently emerged as a globally disseminated pathogenic strain that often causes severe food-borne infections.Unlike most pandemic serotypes of Salmonella,the ST1541 strains harbored ColRNA1 plasmids that contain qnr-like determinants known to be responsible for the increasing incidence of ciprofloxacin-resistant food-borne Salmonella infections.In this study,we conducted a genomic analysis of a global collection of 388 S.Corvallis ST1541 strains collected within a twenty-year period.We investigated the genetic characteristics of plasmid-mediated quinolone resistance(PMQR)plasmids harbored by these S.Corvallis strains,established a mini-mum spanning tree(MST)to determine the temporal and spatial distribution of the top 10 MST clusters,inferred a time-phylogenies for the major sub-lineages and traced the routes of international dissemination of this serotype strains.Bayesian algorithm predicted that UK might be the origin of S.Corvallis strains currently prevalent in various countries.This idea is supported by the observation of the emergence of intercontinental-disseminated clonal strains and extensive transmission of the extensive-drug resistance(XDR)-encoding plasmid pSA663.This study there-fore provides valuable insight into the evolution of globally transmitted S.Corvallis strains and suggests a need to strengthen cooperation between different countries to control the dissemination of these drug-resistant bacteria.

Detection of a reassortant swine H1N2 influenza A virus from pigs in Hong Kong

Dear Editor,Influenza A viruses(IAVs)are responsible for significant respiratory illnesses in humans and a broad range of animal species.Repeated outbreaks and the rapid spread of genetically and antigenically distinct IAVs represent a considerable challenge for swine production.Pigs are susceptible to avian and human IAV infections and are considered“mixing vessels”where human,avian,and swine IAVs can recombine and generate novel reassortant influenza viruses with pandemic potential(Vincent et al.,2014).

Evaluating the effectiveness of control measures in multiple regions during the early phase of the COVID-19 pandemic in 2020

The number of COVID-19 confirmed cases rapidly grew since the SARS-CoV-2 virus was identified in late 2019.Due to the high transmissibility of this virus,more countries are experiencing the repeated waves of the COVID-19 pandemic.However,with limited manufacturing and distribution of vaccines,control measures might still be the most critical measures to contain outbreaks worldwide.Therefore,evaluating the effectiveness of various control measures is necessary to inform policymakers and improve future preparedness.In addition,there is an ongoing need to enhance our understanding of the epidemiological parameters and the transmission patterns for a better response to the COVID-19 pandemic.This review focuses on how various models were applied to guide the COVID-19 response by estimating key epidemiologic parameters and evaluating the effectiveness of control measures.We also discuss the insights obtained from the prediction of COVID-19 trajectories under different control measures scenarios.

Surveillance of Multidrug-Resistant Bacterial Infections in Non-Adult Patients-Zhejiang Province,China,2014-2019

ABSTRACT Introduction:Antimicrobial resistance has become a major public health threat globally.The prevalence of multidrug-resistant(MDR)bacterial infections increased substantially among inpatients under 18 years of age in recent years.In Zhejiang Province,China,the trends of drug-resistance in non-adult patients from 2014 to 2019 were monitored,aiming to determine the variation patterns and epidemiological features of MDR strains.

Towards an actionable One Health approach

Background Despite the increasing focus on strengthening One Health capacity building on global level,challenges remain in devising and implementing real-world interventions particularly in the Asia-Pacific region.Recognizing these gaps,the One Health Action Commission(OHAC)was established as an academic community for One Health action with an emphasis on research agenda setting to identify actions for highest impact.Main text This viewpoint describes the agenda of,and motivation for,the recently formed OHAC.Recognizing the urgent need for evidence to support the formulation of necessary action plans,OHAC advocates the adoption of both bottom-up and top-down approaches to identify the current gaps in combating zoonoses,antimicrobial resistance,addressing food safety,and to enhance capacity building for context-sensitive One Health implementation.Conclusions By promoting broader engagement and connection of multidisciplinary stakeholders,OHAC envisions a collaborative global platform for the generation of innovative One Health knowledge,distilled practical experience and actionable policy advice,guided by strong ethical principles of One Health.
