文摘Helicobacter pylori(H.pylori)infection remains a pivotal driver of chronic gastritis,peptic ulcer,gastric mucosa-associated lymphoid tissue lymphoma and gastric cancer,yet its eradication is increasingly frustrated by climbing antibiotic resistance and intolerable side-effects of standard triple or quadruple therapies.In recent years,fecal microbiota transplantation(FMT),a strategy that reconstructs the gut ecosystem by introducing a healthy donor microbiome,has emerged as a novel adjunct or alternative.By competitively excluding H.pylori,reinforcing mucosal barrier integrity,modulating host immunity and secreting bacteriocins,FMT can raise eradication rates,relieve dyspeptic symptoms and lower recurrence.This review synthesizes up-to-date pre-clinical,pilot and controlled clinical data,dissects underlying mechanisms,compares delivery routes,donor screening protocols and safety profiles,and discusses regulatory,ethical and standardization hurdles that must be overcome before large-scale clinical application.
文摘As a critical department ensuring the sterility of hospital instruments,the Sterile Supply Center(SSC)directly impacts the sterility status of clinical instruments through its sterilization qualification rate.Geriatric patients,due to physiological decline and compromised immune function,constitute a high-risk group for hospital-acquired infections,with more stringent requirements for instrument sterility.This paper analyzes the current status and influencing factors of sterilization qualification rates in SSCs,explores the mechanistic association between sterilization qualification rates and infections in geriatric departments,and proposes targeted strategies to improve sterilization qualification rates.It highlights the pivotal role of SSC instrument sterilization in infection prevention and control for geriatric patients,providing theoretical basis and practical guidance for optimizing SSC management,reducing infection rates in geriatric departments,and ensuring the safety of elderly patients’medical care.These findings aim to enhance overall infection management standards in hospitals.

文摘Recent increases in infectious diseases affecting the central nervous system have raised concerns about their role in neuroinflammation and neurodegeneration.Viral pathogens or their products can invade the central nervous system and cause damage,leading to meningitis,encephalitis,meningoencephalitis,myelitis,or post-infectious demyelinating diseases.Although neuroinflammation initially has a protective function,chronic inflammation can contribute to the development of neurodegenerative diseases.Mechanisms such as protein aggregation and cellular disturbances are implicated with specific viruses such as herpes simplex virus type 1 and Epstein-Barr virus being associated with Alzheimer's disease and multiple sclerosis,respectively.Extracellular nucleotides,particularly adenosine triphosphate and its metabolites are released from activated,infected,and dying cells,acting as alarmins mediating neuroinflammation and neurodegeneration.When viruses infect central nervous system cells,adenosine triphosphate is released as an alarmin,triggering inflammatory responses.This process is mediated by purinergic receptors,divided into two families:P1,which responds to adenosine,and P2,activated by adenosine triphosphate and other nucleotides.This review highlights how specific viruses,such as human immunodeficiency virus type 1,Theiler's murine encephalomyelitis virus,herpes simplex virus type 1,Epstein-Barr virus,dengue virus,Zika virus,and severe acute respiratory syndrome coronavirus 2,can initiate inflammatory responses through the release of extracellular nucleotides,particularly adenosine triphosphate,which act as critical mediators in the progression of neuroinflammation and neurodegenerative disorders.A better understanding of purinergic signaling pathways in these diseases may suggest new potential therapeutic strategies for targeting neuroinflammation to mitigate the long-term consequences of viral infections in the central nervous system.

文摘BACKGROUND Patients with hepatitis B virus(HBV)infection require chronic and personalized care to improve outcomes.Large language models(LLMs)can potentially provide medical information for patients.AIM To examine the performance of three LLMs,ChatGPT-3.5,ChatGPT-4.0,and Google Gemini,in answering HBV-related questions.METHODS LLMs’responses to HBV-related questions were independently graded by two medical professionals using a four-point accuracy scale,and disagreements were resolved by a third reviewer.Each question was run three times using three LLMs.Readability was assessed via the Gunning Fog index and Flesch-Kincaid grade level.RESULTS Overall,all three LLM chatbots achieved high average accuracy scores for subjective questions(ChatGPT-3.5:3.50;ChatGPT-4.0:3.69;Google Gemini:3.53,out of a maximum score of 4).With respect to objective questions,ChatGPT-4.0 achieved an 80.8%accuracy rate,compared with 62.9%for ChatGPT-3.5 and 73.1%for Google Gemini.Across the six domains,ChatGPT-4.0 performed better in terms of diagnosis,whereas Google Gemini demonstrated excellent clinical manifestations.Notably,in the readability analysis,the mean Gunning Fog index and Flesch-Kincaid grade level scores of the three LLM chatbots were significantly higher than the standard level eight,far exceeding the reading level of the normal population.CONCLUSION Our results highlight the potential of LLMs,especially ChatGPT-4.0,for delivering responses to HBV-related questions.LLMs may be an adjunctive informational tool for patients and physicians to improve outcomes.Nevertheless,current LLMs should not replace personalized treatment recommendations from physicians in the management of HBV infection.
文摘BACKGROUND Liver transplant(LT)recipients are susceptible to carbapenem-resistant Klebsiella pneumoniae(CRKP)infections.Comprehensive research addressing the incidence,timing,infection sites,resistance patterns,treatment options,and associated risk factors among LT recipients with CRKP is now lacking.AIM To assess the incidence,resistance,therapy,and risk factors of CRKP infections post-LT,and to evaluate the impact of them on prognosis.METHODS A retrospective study was conducted,including 430 consecutive patients who underwent LT between January 2015 and June 2023.This study aimed to investigate the risk factors for CRKP infections and their influence on outcomes using logistic regression analysis.RESULTS Among the 430 patients who underwent LT,20(4.7%)experienced at least one documented CRKP infection within 3 months post-transplantation.The median time from LT to the onset of CRKP infections was 6.5 days.The lungs and bloodstream were the most common sites of CRKP infections.CRKP isolates were relatively susceptible to ceftazidime/avibactam(93.7%),polymyxin B(90.6%),and tigecycline(75.0%)treatment.However,all isolates were resistant to piperacillin/tazobactam,ceftazidime,cefepime,aztreonam,meropenem,and levofloxacin treatment.Recipients with CRKP infections had a mortality rate of 35%,the rate was 12.5%for those receiving ceftazidime/avibactam therapy.Multivariate analysis identified female sex[odds ratio(OR)=3.306;95%confidence interval(CI):1.239-8.822;P=0.017],intraoperative bleeding≥3000 mL(OR=3.269;95%CI:1.018-10.490;P=0.047),alanine aminotransferase on day 1 post-LT≥1500 U/L(OR=4.370;95%CI:1.686-11.326;P=0.002),and post-LT mechanical ventilation(OR=2.772;95%CI:1.077-7.135;P=0.035)as significant variables associated with CRKP.CRKP infections were related to an intensive care unit length(ICU)of stay≥7 days and 6-month all-cause mortality post-LT.CONCLUSION CRKP infections were frequent complications following LT,with poor associated outcomes.Risk factors for post-LT CRKP infections included female sex,significant intraoperative bleeding,elevated alanine aminotransferase levels,and the need for mechanical ventilation.CRKP infections negatively impacted survival and led to prolonged ICU stays.
文摘BACKGROUND Transfusion transmissible infections(TTIs)are illnesses spread through contaminated blood or blood products.In India,screening for TTIs such as hepatitis B virus(HBV),hepatitis C virus(HCV),human immunodeficiency virus(HIV)-I/II,malaria,and syphilis is mandatory before blood transfusions.Worldwide,HCV,HBV,and HIV are the leading viruses causing mortality,affecting millions of people globally,including those with co-infections of HIV/HCV and HIV/HBV.Studies highlight the impact of TTIs on life expectancy and health risks,such as liver cirrhosis,cancer,and other diseases in individuals with chronic HBV.Globally,millions of blood donations take place annually,emphasizing the importance of maintaining blood safety.AIM To study the prevalence of TTIs,viz.,HBV,HCV,HIV I/II,syphilis,and malaria parasite(MP),among different blood donor groups.METHODS The study assessed the prevalence of TTIs among different blood donor groups in Delhi,India.Groups included total donors,in-house donors,total camp donors,institutional camp donors,and community camp donors.Tests for HIV,HBV,and HCV were done using enzyme-linked immunosorbent assay,while syphilis was tested with rapid plasma reagins and MP rapid card methods.The prevalence of HBV,HCV,HIV,and syphilis,expressed as percentages.Differences in infection rates between the groups were analyzed usingχ²tests and P-values(less than 0.05).RESULTS The study evaluated TTIs among 42158 blood donors in Delhi.The overall cumulative frequency of TTIs in total blood donors was 2.071%,and the frequencies of HBV,HCV,HIV-I/II,venereal disease research laboratory,and MP were 1.048%,0.425%,0.221%,0.377%,and 0.0024%,respectively.In-house donors,representing 37656 donors,had the highest transfusion transmissible infection(TTI)prevalence at 2.167%.Among total camp donors(4502 donors),TTIs were identified in 1.266%of donors,while community camp donors(2439 donors)exhibited a prevalence of 1.558%.Institutional camp donors(2063 donors)had the lowest TTI prevalence at 0.921%.Statistical analysis revealed significant differences in overall TTI prevalence,with total and in-house donors exhibiting higher rates compared to camp donors.CONCLUSION Ongoing monitoring and effective screening programs are essential for minimizing TTIs.Customizing blood safety measures for different donor groups and studying socio-economic-health factors is essential to improving blood safety.

文摘This study primarily aimed to investigate the prevalence of human papillomavirus(HPV)and other common pathogens of sexually transmitted infections(STIs)in spermatozoa of infertile men and their effects on semen parameters.These pathogens included Ureaplasma urealyticum,Ureaplasma parvum,Chlamydia trachomatis,Mycoplasma genitalium,herpes simplex virus 2,Neisseria gonorrhoeae,Enterococcus faecalis,Streptococcus agalactiae,Pseudomonas aeruginosa,and Staphylococcus aureus.A total of 1951 men of infertile couples were recruited between 23 March 2023,and 17 May 2023,at the Department of Reproductive Medicine of The First People’s Hospital of Yunnan Province(Kunming,China).Multiplex polymerase chain reaction and capillary electrophoresis were used for HPV genotyping.Polymerase chain reaction and electrophoresis were also used to detect the presence of other STIs.The overall prevalence of HPV infection was 12.4%.The top five prevalent HPV subtypes were types 56,52,43,16,and 53 among those tested positive for HPV.Other common infections with high prevalence rates were Ureaplasma urealyticum(28.3%),Ureaplasma parvum(20.4%),and Enterococcus faecalis(9.5%).The prevalence rates of HPV coinfection with Ureaplasma urealyticum,Ureaplasma parvum,Chlamydia trachomatis,Mycoplasma genitalium,herpes simplex virus 2,Neisseria gonorrhoeae,Enterococcus faecalis,Streptococcus agalactiae,and Staphylococcus aureus were 24.8%,25.4%,10.6%,6.4%,2.4%,7.9%,5.9%,0.9%,and 1.3%,respectively.The semen volume and total sperm count were greatly decreased by HPV infection alone.Coinfection with HPV and Ureaplasma urealyticum significantly reduced sperm motility and viability.Our study shows that coinfection with STIs is highly prevalent in the semen of infertile men and that coinfection with pathogens can seriously affect semen parameters,emphasizing the necessity of semen screening for STIs.
文摘This article aims to deepen the understanding of the role of Helicobacter pylori(H.pylori)infection in the development of cholelithiasis,initiated by the article by Yao et al,who investigated the potential link between H.pylori infection and the development of cholelithiasis through a multicenter retrospective study on an Asian population of over 70000 participants.They also performed a compre-hensive analysis of previously published studies on H.pylori and cholelithiasis,finding a positive association therein[odds ratio(OR)=1.103,P=0.049].Patients positive for H.pylori also had lower levels of total and direct bilirubin,but higher levels of total cholesterol and low-density lipoprotein cholesterol compared to uninfected patients(P<0.05).Cohort studies have confirmed that H.pylori is a risk factor for cholelithiasis(P<0.0001),and aggregate analyses of case-control and cross-sectional studies have shown a positive association between H.pylori and cholelithiasis in Asia(OR=1.599,P=0.034),but not in Europe(OR=1.277,P=0.246).Moreover,H.pylori appears to be related to a higher ratio of choledocho-lithiasis/cholecystolithiasis(OR=3.321,P=0.033).The authors conclude that H.pylori infection is positively correlated with cholelithiasis,particularly with the choledocholithiasis phenotype,especially in Asia,and it is potentially related to bilirubin and cholesterol metabolism.

文摘Objective This study aims to analyze the burden of lower respiratory infections in Chinese elderly people aged 70 and above.Methods This study utilized Global Burden of Disease(GBD)1990-2050 prediction data to analyze changes in mortality rates and disability-adjusted life year(DALY)rates for lower respiratory infections in the elderly population(aged 70 and above)in China from 1990 to 2050.It also discusses future trends in the burden of lower respiratory infections(LRI)in China under different scenarios.Results According to GBD predictions,the burden of lower respiratory infections in the elderly aged 70 years and above in China is lower than the global average.The burden has been decreasing from 1990 to 2020,but is projected to increase from 2020 to 2050.Scenario-based predictions suggest that,under scenarios involving improvements in nutrition and vaccination,the burden of lower respiratory infections in the elderly in China is expected to be the lowest in 2050.Conclusion This study indicates that the burden of lower respiratory infections in elderly people aged 70 years and above in China remains a significant public health issue and may worsen.The government should consider strengthening the preventive measures and management strategies for respiratory infections in the elderly population.
文摘In this paper,we analyze the article published by El Labban et al,which explores the impact of cirrhosis on patients with necrotizing fasciitis.The authors conclude that cirrhosis is a significant risk factor for increased in-hospital morbidity and mortality in this patient population.Building upon their final observation regarding the importance of understanding this association,we will delve into the topic of infections in patients with liver cirrhosis.These patients exhibit intrinsic characteristics that make them particularly susceptible to infections,both bacterial and fungal.This heightened risk not only increases the likelihood of severe infections but also makes them a common trigger for acute decompensations,including the development of acute-on-chronic liver failure,which markedly worsens prognosis and mortality.Infections in patients with cirrhosis often require a more aggressive and rapid diagnostic and therapeutic approach due to the higher risk of nosocomial infections,multidrug-resistant organisms,and atypical clinical presentations.Delayed or inadequate management can lead to unfavorable outcomes,further complicating the course of their underlying liver disease.The aim of this article is to emphasize the importance of early and appropriate management in patients with cirrhosis with infections.Evidence supports that timely and tailored interventions not only improve clinical outcomes but also reduce mortality.By raising awareness among clinicians about the complexity of these cases,we hope to contribute to optimizing the care of this high-risk population.
