Method: DDG-3300K liver reserve function analyzer was applied to 5464 patients at the department of infectious diseases. The reasons for failed detection and complications related to the detection were analyzed, and the measures for improving the nursing procedures were proposed. Result: Among the 5464 patients, the detections were successful at the first attempt in 5458 patients;2 patients had leakage of liquid;2 patients were poorly prepared, and 1 case failed because of mistaken selection of CO mode, which led to adverse drug reactions;1 case did not finish the detection due to anaphylactic shock;8 patients had nausea and 6 patients had skin rash on the four limbs and torso during the detection. Conclusion: It is necessary to formulate the nursing procedures for the use of DDG-3300K liver reserve function analyzer. Moreover, preparatory work, health education, refined nursing procedures and skillful operations are closely related to the success rate and accuracy of the detection.展开更多

Methods: It was a retrospective study of descriptive and analytic type lasting one year six months (18 months) from January 1st, 2016 to June 30th, 2017 which involved patients admitted and hospitalized for cerebral toxoplasmosis in HIV field. Data enter was performed by Epi data 3.1 software and SPSS 21 software for statistical analysis. The threshold of significance was p Results: We observed 87 cases of cerebral toxoplasmosis (CT). The mean age was 38.53 ± 12.16. The clinical signs were mainly infectious syndrome (100%), headache (69.0%), confusion (46.0%) and meningeal syndrome (41.4%). The lethality was 37.9%. Living with a partner (p = 0.007), CD4 at initiation of antiretroviral therapy 3 (p = 0.009), and coma (p = 0.02) were the factors associated with death. Conclusion: This study showed that cerebral toxoplasmosis is associated with very high morbidity and mortality in the Infectious Diseases Department of Donka National Hospital. Living in a relationship, CD4 counts at baseline 3 and coma were independently associated with death. Special attention to these factors associated with infectious resuscitation and primary prevention in patients with a CD4 T lymphocyte count below 200 cells/mm may improve the prognosis of this pathology.展开更多

Real-time quantitative polymerase chain reaction (RT-qPCR) was the most widely used detection technique during the COVID-19 outbreak. However, it cannot discriminate between intact infectious viruses and surface-distorted, non-infectious virus particles or naked viral RNA. In this study, we present a strategy for the specific detection of infectious coronaviruses by combining viral receptor capture and reverse transcription loop-mediated isothermal amplification (RT-LAMP). We successfully applied this strategy to detect infectious virus particles of the SARS-CoV-2 surrogate virus and the human coronavirus NL63 (HCoV-NL63). Virus particles were first captured on ELISA plates coated with the recombinant human angiotensin-converting enzyme 2 (hACE2) receptor. Viral RNA was then extracted from the particles and detected by RT-LAMP using virus-specific primers. In our experimental setting, the proposed method had a minimum detection limit (LOD) of 90 PFU/mL, sensitivity of 96.2%, and specificity of 100%. Our study provides a proof-of-concept that viral receptor capture combined with RT-LAMP can differentiate infectious coronaviruses from non-infectious virions or naked viral RNA. This paves the way for this virus detection strategy to become a mainstream tool for the management, prevention and control of epidemic coronavirus diseases.展开更多

Objective: To describe the epidemiological, clinical and evolutionary characteristics of parasitosis diagnosed in the infectious diseases department of the Yalgado Ouédraogo University Hospital. Patients and Method: This is a descriptive cross-sectional study with retrospective data collection during the period from January 1, 2010 to August 31, 2022. Results: From January 1, 2010 to August 31, 2022, a total of 2829 patients were admitted to the infectious diseases department of the Yalgado Ouédraogo University Hospital in Ouagadougou. Among them, 624 patients suffered from parasitic pathologies, representing a hospital prevalence of 22%. The patients were predominantly male with a sex ratio of 1.1. The average age was 34 years ± 11. Most patients (74.7%) lived in the capital city of Ouagadougou. Ten percent (10%) of the patients with parasitosis were infected with HIV (PLHIV). Out of a total of 624 cases of parasitosis, protozoosis represented 97%, of which 80% were malaria cases. Clinical signs were dominated by neurological signs, digestive signs and dehydration. Comorbidities were dominated by HIV infection, tuberculosis and digestive candidiasis. Under treatment, the evolution was marked by a lethality of 10%. Conclusion: Protozoosis were the most frequently diagnosed. They were dominated by malaria and opportunistic parasitosis during AIDS. These results argue for a revitalization of voluntary HIV testing and careful management of PLHIV.展开更多

The objective of this study is to determine the extent of this prescription. Patients and Methods: This was a cross-sectional study with retrospective data collection of patients hospitalized in the infectious diseases department in the period from January 1, 2005 to December 31, 2020. The records of patients who received probabilistic antibiotic therapy were included. Results: During the study period, 330 patients had received probabilistic antibiotic therapy. The majority of patients were male (53%), with a sex ratio of 1.12. The mean age of the patients was 33 years ± 14. The age range of 20 to 40 years was the most represented (42%). Fifteen percent (15%) of patients were living with HIV. The majority of patients were from urban areas (56.4%). Forty-nine percent (49%) of the patients worked in the informal sector. Clinically, the reasons for consultation were dominated by fever, alteration of general condition, neurological disorders, digestive disorders, respiratory signs, urinary signs and diffuse pain. The physical examination showed that 48.1% of the patients had meningeal irritation syndrome, 10% had convulsions and 10% had focal signs, trismus was present in 4% of the patients and facial paralysis in 3%. In the digestive system, hepatomegaly was present in 29% of patients and digestive candidiasis in 31%. Respiratory examination showed crepitus and fluid effusion syndrome in 26.83% and 20.62% of patients respectively. The presumptive diagnosis was dominated by bacterial meningitis, salmonellosis and bronchopneumonia with banal germs. In terms of treatment, the beta-lactam family of drugs was the most prescribed. They were followed by aminoglycosides and fluoroquinolones. The evolution was marked by the death of 50 patients (15%). Conclusion: The most prescribed molecules belong to the family of Beta-lactam. And this prescription improved the outcome of patients. Bacterial susceptibility studies will allow better orientation of probabilistic antibiotic therapy in order to limit the emergence of multi-resistant bacteria.展开更多

The interactions involve physiological and ecological mechanisms and they have evolved under a given set of environmental conditions. Environmental change, therefore, will alter host-pathogen-vector interactions and, consequently, the distribution, in- tensity, and dynamics of infectious diseases. Here, we review how climate change may impact infectious diseases of aquatic and terrestrial wildlife. Climate change can have direct impacts on distribution, life cycle, and physiological status of hosts, pathogens and vectors. While a change in either host, pathogen or vector does not necessarily translate into an alteration of the disease, it is the impact of climate change on the interactions between the disease components which is particularly critical for altered disease risks. Finally, climate factors can modulate disease through modifying the ecological networks host-pathogen-vector systems are belonging to, and climate change can combine with other environmental stressors to induce cumulative effects on infectious dis- eases. Overall, the influence of climate change on infectious diseases involves different mechanisms, it can be modulated by phenotypic acclimation and/or genotypic adaptation, it depends on the ecological context of the host-pathogen-vector interactions, and it can be modulated by impacts of other stressors. As a consequence of this complexity, non-linear responses of disease sys- tems under climate change are to be expected. To improve predictions on climate change impacts on infectious disease, we sug- gest that more emphasis should be given to the integration of biomedical and ecological research for studying both the physio- logical and ecological mechanisms which mediate climate change impacts on disease, and to the development of harmonized methods and approaches to obtain more comparable results, as this would support the discrimination of case-specific versus gen- eral mechanisms .展开更多

Hand hygiene has been recognized for over a century as an effective measure to prevent healthcare associated infections in healthcare settings, the objective of this study was to appreciate the practice of hand hygiene during care by health professionals in the medical-surgical emergency department of the Donka National Hospital. Methods: It was a cross-sectional, analytical study. Data collection took place from March 1 to April 30, 2021. The study covered all health professionals, namely doctors, nurses, laboratory technicians, radiography technicians, pharmacists, students, stretcher bearers, surfactants who were present at the time of the study period. Results: During the study period, out of a total of 104 registered health professionals, we surveyed 99, which is a rate of 95%. The most represented age group was [30 - 39 years] with an average of 37.17 ± 10.34 years, and extremes of 22 years to 65 years. The male sex was the most dominant or 59.60% compared to the female sex or 40.40% with a sex ratio of 1.47. The hand hygiene compliance rate was low at 21%. The practice of hand hygiene during care for 100% of health professionals was very low, at 8.08%. No factors influence the observance of the practice of hand hygiene and the socio-professional characteristics of the conditions of provision of care activities. Conclusion: Hand hygiene during care is an essential aspect that must be considered as an essential measure in the prevention of infections in this period of the COVID-19 pandemic.展开更多

Living with a partner (p = 0.007), CD4 at initiation of antiretroviral therapy 3 (p = 0.009), and coma (p = 0.02) were the factors associated with death. Conclusion: This study showed that cerebral toxoplasmosis is associated with very high morbidity and mortality in the Infectious Diseases Department of Donka National Hospital. Living in a relationship, CD4 counts at baseline 3 and coma were independently associated with death. Special attention to these factors associated with infectious resuscitation and primary prevention in patients with a CD4 T lymphocyte count below 200 cells/mm may improve the prognosis of this pathology.

文摘Global environmental changes including climate warming,extreme weather events,ambient air pollution,freshwater contamination,and landscape transformation are reshaping the epidemiology of infectious diseases with unprecedented complexity,particularly in the post-COVID-19 era.This review synthesizes evidence from the past decade(2015-2024)to systematically elucidate how key environmental drivers modulate pathogen emergence,transmission dynamics,and clinical outcomes,with a focus on underlying mechanistic pathways.Specifically,we highlight:(1)the temperature-and precipitation-dependent transmission of vector-borne diseases(e.g.,malaria,dengue)via expanded vector habitats and accelerated pathogen incubation;(2)the exacerbation of respiratory infections(including COVID-19)by particulate matter(PM2.5)and nitrogen dioxide(NO2)through impaired mucosal immunity and enhanced inflammatory responses;(3)the persistence of diarrheal diseases in low-and middle-income countries(LMICs)linked to water insecurity and climate-induced infrastructure failure;and(4)zoonotic spillover risks amplified by urbanization and deforestation-driven human-wildlife interface disruption.Integrating the One Health socioecological framework,we further summarize methodological advances from high-resolution genomic surveillance to climate-informed machine learning models that have improved causal inference and predictive accuracy.Our synthesis confirms that environmental factors are not merely contextual but central,modifiable determinants of infectious disease risk,with disproportionate impacts on vulnerable populations.To mitigate future threats,we emphasize the urgency of interdisciplinary collaboration,integrated environmental-health monitoring platforms,and climate-resilient public health policies tailored to post-pandemic challenges.This review provides a timely roadmap for translating environmental epidemiology insights into actionable strategies to strengthen global health resilience.
文摘Objective:To evaluate laboratory findings that predict bacterial meningitis in emergency service and their diagnostic effectiveness.Methods:This retrospective cohort study analyzed data from patients presenting with meningitis symptoms at a referral hospital in Mersin,Turkey,between January 2019 and January 2022.Clinical findings and laboratory results,including leukocyte count,C-reactive protein(CRP),and procalcitonin levels in blood,were examined.Logistic regression,Chi square test,and receiver operating characteristics(ROC)curve analyses assessed the predictive value of these parameters.Results:A total of 199 participants were included in the study;99 patients were diagnosed with meningitis after lumbar puncture and 100 served as controls.Patients with meningitis exhibited significantly higher leukocyte counts(median:11890×10^(3)/μL vs.7905×10^(3)/μL,P<0.001)and CRP levels(median:6.00 mg/dL vs.0.95 mg/dL,P<0.001)compared to controls.Procalcitonin levels were significantly elevated in meningitis patients(median:0.21 ng/mL vs.0.10 ng/mL,P<0.001).Logistic regression identified albumin(OR=0.16,95%CI=0.06-0.40),and CRP(OR=1.18,95%CI=1.08-1.28)as independent predictors of meningitis.ROC analysis for CRP demonstrated a sensitivity of 80.6%and specificity of 70.0%at a cut-off value of 2.23 mg/dL(AUC=0.792).Conclusions:Elevated albumin levels and CRP contents in the blood were significant predictors of meningitis in emergency service.Early identification of predictive markers may aid in timely lumbar puncture and management of atypical cases.

文摘Rapid and accurate detection of infectious virus particles, not just viral nucleic acid, is essential to avoid unnecessary quarantine and effectively control the spread of viral diseases such as coronavirus disease 2019 (COVID-19), severe acute respiratory syndrome (SARS), and Middle East respiratory syndrome (MERS). Real-time quantitative polymerase chain reaction (RT-qPCR) was the most widely used detection technique during the COVID-19 outbreak. However, it cannot discriminate between intact infectious viruses and surface-distorted, non-infectious virus particles or naked viral RNA. In this study, we present a strategy for the specific detection of infectious coronaviruses by combining viral receptor capture and reverse transcription loop-mediated isothermal amplification (RT-LAMP). We successfully applied this strategy to detect infectious virus particles of the SARS-CoV-2 surrogate virus and the human coronavirus NL63 (HCoV-NL63). Virus particles were first captured on ELISA plates coated with the recombinant human angiotensin-converting enzyme 2 (hACE2) receptor. Viral RNA was then extracted from the particles and detected by RT-LAMP using virus-specific primers. In our experimental setting, the proposed method had a minimum detection limit (LOD) of 90 PFU/mL, sensitivity of 96.2%, and specificity of 100%. Our study provides a proof-of-concept that viral receptor capture combined with RT-LAMP can differentiate infectious coronaviruses from non-infectious virions or naked viral RNA. This paves the way for this virus detection strategy to become a mainstream tool for the management, prevention and control of epidemic coronavirus diseases.
文摘Introduction: Parasitic diseases remain a public health problem in Burkina Faso, as they are in other developing countries. Objective: To describe the epidemiological, clinical and evolutionary characteristics of parasitosis diagnosed in the infectious diseases department of the Yalgado Ouédraogo University Hospital. Patients and Method: This is a descriptive cross-sectional study with retrospective data collection during the period from January 1, 2010 to August 31, 2022. Results: From January 1, 2010 to August 31, 2022, a total of 2829 patients were admitted to the infectious diseases department of the Yalgado Ouédraogo University Hospital in Ouagadougou. Among them, 624 patients suffered from parasitic pathologies, representing a hospital prevalence of 22%. The patients were predominantly male with a sex ratio of 1.1. The average age was 34 years ± 11. Most patients (74.7%) lived in the capital city of Ouagadougou. Ten percent (10%) of the patients with parasitosis were infected with HIV (PLHIV). Out of a total of 624 cases of parasitosis, protozoosis represented 97%, of which 80% were malaria cases. Clinical signs were dominated by neurological signs, digestive signs and dehydration. Comorbidities were dominated by HIV infection, tuberculosis and digestive candidiasis. Under treatment, the evolution was marked by a lethality of 10%. Conclusion: Protozoosis were the most frequently diagnosed. They were dominated by malaria and opportunistic parasitosis during AIDS. These results argue for a revitalization of voluntary HIV testing and careful management of PLHIV.
文摘Introduction: In Burkina Faso, as in most developing countries, limited access to biological tests forces practitioners to resort very often to probabilistic antibiotic therapy. The objective of this study is to determine the extent of this prescription. Patients and Methods: This was a cross-sectional study with retrospective data collection of patients hospitalized in the infectious diseases department in the period from January 1, 2005 to December 31, 2020. The records of patients who received probabilistic antibiotic therapy were included. Results: During the study period, 330 patients had received probabilistic antibiotic therapy. The majority of patients were male (53%), with a sex ratio of 1.12. The mean age of the patients was 33 years ± 14. The age range of 20 to 40 years was the most represented (42%). Fifteen percent (15%) of patients were living with HIV. The majority of patients were from urban areas (56.4%). Forty-nine percent (49%) of the patients worked in the informal sector. Clinically, the reasons for consultation were dominated by fever, alteration of general condition, neurological disorders, digestive disorders, respiratory signs, urinary signs and diffuse pain. The physical examination showed that 48.1% of the patients had meningeal irritation syndrome, 10% had convulsions and 10% had focal signs, trismus was present in 4% of the patients and facial paralysis in 3%. In the digestive system, hepatomegaly was present in 29% of patients and digestive candidiasis in 31%. Respiratory examination showed crepitus and fluid effusion syndrome in 26.83% and 20.62% of patients respectively. The presumptive diagnosis was dominated by bacterial meningitis, salmonellosis and bronchopneumonia with banal germs. In terms of treatment, the beta-lactam family of drugs was the most prescribed. They were followed by aminoglycosides and fluoroquinolones. The evolution was marked by the death of 50 patients (15%). Conclusion: The most prescribed molecules belong to the family of Beta-lactam. And this prescription improved the outcome of patients. Bacterial susceptibility studies will allow better orientation of probabilistic antibiotic therapy in order to limit the emergence of multi-resistant bacteria.

文摘Objectives:Gastric cancer(GC)is among the most prevalent malignancies worldwide,ranking as the fifth most common cancer and the fifth leading cause of cancer-related mortality.This study intends to investigate how Inhibin subunit beta A(INHBA)promotes the progression of GC by activating the mitogen-activated protein kinase(MAPK)signaling pathway via targeting Integrin alpha-6(ITGA6).Methods:Quantitative reverse transcription-Polymerase Chain Reaction(qRT-PCR)and Immunohistochemistry(IHC)were utilised to validate the expression levels of INHBA in GC,which were subsequently correlated with the clinicopathological factors and outcomes.Cellular and animal studies were conducted to ascertain the role of INHBA in GC.RNA-sequencing(RNA-seq)and bioinformatics analysis were used to screen for the downstream target and pathway of INHBA,with Co-immunoprecipitation(Co-IP),Co-Immunofluorescent(Co-IF),Western blot(WB)and Rescue experiments validating their mechanisms of action in GC.Results:IHC and qRT-PCR analysis confirmed that GC tissues exhibited higher INHBA expression than adjacent noncancerous tissues.This elevated INHBA expression was found to be significantly associated with the incidence of tumor lesions,lymph node metastasis,and progression to higher TNM stages.Functional experiments showed that INHBA promoted GC cell proliferation and enhanced their migration and invasion in vitro while inhibiting apoptosis.Animal studies results indicated that INHBA overexpression promoted tumor growth and increased tumor weight and volume.Through a series of experiments,including RNA-seq,Co-IP,Co-IF,WB,and rescue assays,this study demonstrated that INHBA promotes GC progression by targeting ITGA6 to regulate the MAPK signaling pathway.Conclusions:INHBA/ITGA6/MAPK axis can provide new insights into GC therapy.Targeted INHBA inhibition holds promise as a therapeutic approach for GC treatment.

文摘Overproduction of reactive oxygen species(ROS) following ischemic injury triggers an inflammatory response,significantly impeding neurological functional recovery.Nanozymes with potent antioxidative and anti-inflammatory effects thus offer great potential for ischemic stroke treatment.In this study,we developed an ischemia-homing nanozyme by combining melatonin(MT)-loaded honeycomb manganese dioxide(MnO_(2)) nanoflowers with M2-type microglia membranes to rescue the ischemic penumbra.The surface-engineered M2-type microglia membranes provided intrinsic ischemia-homing and blood-brain barrier(BBB)-crossing properties to the biomimetic nanozymes.This nanozyme can not only transforms harmfulsuperoxide anion radicals(^(·)O^(2-)) and hydrogen peroxide(H_(2)O_(2)) into harmless water and oxygen but also scavenges highly toxic hydroxyl radicals(^(·)OH),dramatically lowering intracellular ROS levels.More importantly,the biomimetic nanoparticles reduce cerebral infarct areas and provide significant neuroprotection against ischemic stroke by lowering oxidative stress,inhibiting cell apoptosis,and decreasing inflammation.This study may offer a viable approach for the use of nanozymes in treating ischemic stroke.

文摘Insects represent emerging sources of bioactive peptides and functional materials.Mantidis Oötheca(Sang-Piao-Xiao in Chinese,SPX)serves as an insect-derived medicine for treating kidney disease.This study demonstrated that supernatant(SPX)improved kidney function in adriamycin(ADR)-induced nephropathy mice model.Transcriptomic analysis revealed that SPX inhibited complement activation by targeting the MASP1-C3/C3a receptor(C3aR)pathway.Peptidomic analysis identified 304 peptides from SPX,with 49 peptides selected for evaluation using prediction tools and molecular docking with complement core protein C3.Three peptides(PMGFPFDR,FNDPK,AAQFFNR)exhibiting docking scores below-8.0 were synthesized to verify complement inhibition and anti-fibrotic activities.The synthetic peptide AAQFFNR demonstrated complement inhibitory activity,with an inhibitory complement hemolytic 50%(ICH_(50))value of 24.54μmol·L^(-1),and exhibited superior protective effects in ADR-induced HK-2 cells.Surface plasmon resonance(SPR)assay revealed direct interaction between AAQFFNR and complement C3 with K_(d)value of 16.8μmol·L^(-1).The reno-protective effect of AAQFFNR was subsequently verified in ADR-induced mice.This research provides initial evidence that complement C3-inhibiting peptides from insects demonstrate potential in preventing nephropathy through in silico and in vivo validation approaches.

文摘Objective The aim of this study was to analyze the correlation between the levels of 12 cytokines in the cervical microenvironment and cervical intraepithelial neoplasia in patients with high-risk human papillomavirus(HR-HPV)infection.Methods Female patients(n=73)with HR-HPV infection were enrolled and divided into a high-grade squamous intraepithelial lesion(HSIL)group(n=33)and a non-HSIL(N-HSIL)group(n=40),which include low-grade squamous intraepithelial lesions and inflammation.Healthy screening subjects(n=31)with negative HR-HPV results were enrolled as a control group.We examined contemporaneous plasma and secretory cytokines from 25 study subjects to investigate the difference between systemic cytokine profiles and the local microenvironment immunity using the Wilcoxon matched-pairs signed rank test.The 12 cytokines from cervical secretions were compared between the three groups using the Mann-Whitney test,and logistic regression was used to analyze HSIL and N-HSIL.Results There were statistical differences in eight cytokines(IL-2,IL-6,TNF-α,IFN-γ,IL-1β,IL-12p70,IFN-α,and IL-8)between cervical secretion and plasma of the same patient,and seven cytokines were statistically different between the control and other two groups.We selected four independent variables(TNF-α,IFN-γ,IL-12p70,and IFN-α)commonly identified by univariate regression analysis and non-parametric tests for multivariate logistic regression analysis.Based on this model,HSIL could be predicted in patients with HR-HPV infection,with the area under the curve being 0.76.Conclusion The systemic cytokine profile cannot reflect the local microenvironment immunity,and the occurrence of HSIL is related to the cytokine levels in the cervical microenvironment.

文摘BACKGROUND In China,hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF) is the most common liver failure characterized by serious clinical syndromes of liver decompensation with a very high mortality.Bacterial and/or fungal infections are the most common complications that are associated with high short-term mortality.Bacterial translocation from the intestine,impaired hepatic clearance,and immune paralysis of circulating immune cells are thought to contribute to infectious complications in liver failure.The control of bacterial and fungal infections is the key to improving HBV-ACLF outcomes.Active prevention,early diagnosis,and timely treatment of bacterial and fungal infections are essential for treating HBV-ACLF.AIM To investigate the frequency and role of bacterial and fungal infections in patients with HBV-ACLF.METHODS Patients with HBV-ACLF hospitalized at Taihe Hospital,Hubei University of Medicine from January 2014 to December 2017 were retrospectively enrolled.Patient-related information was retrieved from the hospital case database,including general information,blood biochemistry,complications,etc.According to the occurrence of secondary infection or not,the patients were divided into an infection group and a non-infection group.The sites,types,and incidences of bacterial and fungal infections and the influence of infections on the prognosis of HBV-ACLF were statistically analyzed.The risk factors for infections were assessed by unconditional logistic regression.RESULTS There were 174 cases of HBV-ACLF that met the enrollment criteria,of which 114 (65.52%) were diagnosed with infectious complications.Infections occurred in the abdominal cavity (87 cases),respiratory tract (51 cases),urinary tract (18 cases),and biliary tract (10 cases).Patients with infectious complications had a significantly higher 28-d mortality (70.18%,80/114) than those without (40.00%,24/60)(70.18% vs 40.00%,P < 0.05).And patients with infectious complications had a much higher incidence of non-infectious complications (54.39%,62/114)(54.39% vs 15.00%,P < 0.05),leading to an extremely high 28-d mortality of 88.71%(55/62)(P < 0.05).The grade of liver failure,period of hospital stay ≥ 30 d,age ≥ 45 years,and percentage of neutrophils > 70% were identified as risk factors for infectious complications.CONCLUSION The high incidence of infectious complications in patients with HBV-ACLF is associated with severity and deterioration of the disease and may contribute to the extremely high mortality of these patients.
文摘The present study aimed to establish a list of parameters indicative of pathogen invasion and develop a predictive model to distinguish the etiologies of fever of unknown origin (FUO) into infectious and non-infectious causes.From January 2014 to September 2017,431 patients with FUO were prospectively enrolled in the study population.This study established a list of 26 variables from the following 4aspects:host factors,epidemiological factors,behavioral factors,and iatrogenic factors.Predefined predicted variables were included in a multivariate logistic regression analysis to develop a predictive model.The predictive model and the corresponding scoring system were developed using data from the confirmed diagnoses and 9 variables were eventually identified.These factors were incorporated into the predictive model.This model discriminated between infectious and non-infectious causes of FUO with an AUC of 0.72,sensitivity of 0.71, and specificity of 0.63.The predictive model and corresponding scoring system based on factors concerning pathogen invasion appear to be reliable screening tools to discriminate between infectious and non-infectious causes of FUO.

文摘Nervous system infections are among the most important diseases in travellers.Healthy travellers might be exposed to infectious agents of central nervous system,which may require in-patient care.Progressive course is not uncommon in this family of disorders and requires swift diagnosis.An overview of the available evidence in the field is.therefore,Urgent to pave the way to increase the awareness of travel-medicine practitioners and highlights dark areas for future research.In November 2013,data were collected from PubMed,Scopus,and Web of knowledge(1980 to2013) including books,reviews,and peer-reviewed literature,Works pertained to pre-travel care,interventions,vaccinations related neurological infections were retrieved.Here we provide information on pre-travel care,vaccination,chronic nervous system disorders,and post-travel complications.Recommendations with regard to knowledge gaps,and state-of-the-art research are made.Given an increasing number of international travellers,novel dynamic ways are available for physicians to monitor spread of central nervous system infections.Newer research has made great progresses in developing newer medications,detecting the spread of infections and the public awareness.Despite an ongoing scientific discussion in the field of travel medicine,further research is required for vaccine development,state-of-the-art laboratory tests,and genetic engineering of vectors.
文摘Infectious diseases are the common enemies of mankind.In the course of historical development,they persistently threaten human health and safety.Even today,despite the developments in medical science,we cannot escape the fear and suffering caused by infectious diseases.Whether in ancient or modern times,the source of infection,route of transmission,and a susceptible population are the three key conditions for the prevalence and spread of infectious diseases.All factors closely related to these three conditions can affect the prevalence of infectious diseases.China is one of the cradles of world civilization.The ancient people accumulated a great deal of experience and lessons in the long struggle against infectious diseases.In the face of the current threat posed by widespread infectious disease,it is imperative to review and summarize ancient Chinese ideas and health policies on epidemic prevention and control to inspire contemporary efforts in the prevention and control of infectious disease.The combination of prevention-oriented epidemic prevention ideology and traditional medicine provides valuable insights,especially for impoverished and medically underserved regions.

文摘The current study used multivariable logistic regression analysis to investigate associations between the intake frequencies of 13 food groups(or four diet groups)and infectious diseases.The analysis included 487849 participants from the UK Biobank,with 75209 participants diagnosed with infectious diseases.Participants reporting the highest intake frequency of processed meat(odds ratio[OR]=1.0964,95%confidence interval[CI]:1.0622–1.1318)and red meat(OR=1.0895,95%CI:1.0563–1.1239)had a higher risk of infectious diseases,compared with those with the lowest intake frequency.Consuming fish 2.0–2.9 times(OR=0.8221,95%CI:0.7955–0.8496),cheese≥5.0 times(OR=0.8822,95%CI:0.8559–0.9092),fruit 3.0–3.9 servings(OR=0.8867,95%CI:0.8661–0.9078),and vegetables 2.0–2.9 servings(OR=0.9372,95%CI:0.9189–0.9559)per week were associated with a lower risk of infection.Low meat-eaters(OR=0.9404,95%CI:0.9243–0.9567),fish-eaters(OR=0.8391,95%CI:0.7887–0.8919),and vegetarians(OR=0.9154,95%CI:0.8561–0.9778)had a lower risk of infectious diseases,compared with regular meat-eaters.The mediation analysis revealed that glycosylated hemoglobin,white blood cell count,and body mass index served as the mediators in the associations between diet and infectious diseases.The current study indicates that the intake frequency of food groups is a risk factor for infectious diseases,and fish-eaters have a lower risk of infection.
文摘Infectious diseases result from the interactions of host, pathogens, and, in the case of vector-borne diseases, also vec- tors. The interactions involve physiological and ecological mechanisms and they have evolved under a given set of environmental conditions. Environmental change, therefore, will alter host-pathogen-vector interactions and, consequently, the distribution, in- tensity, and dynamics of infectious diseases. Here, we review how climate change may impact infectious diseases of aquatic and terrestrial wildlife. Climate change can have direct impacts on distribution, life cycle, and physiological status of hosts, pathogens and vectors. While a change in either host, pathogen or vector does not necessarily translate into an alteration of the disease, it is the impact of climate change on the interactions between the disease components which is particularly critical for altered disease risks. Finally, climate factors can modulate disease through modifying the ecological networks host-pathogen-vector systems are belonging to, and climate change can combine with other environmental stressors to induce cumulative effects on infectious dis- eases. Overall, the influence of climate change on infectious diseases involves different mechanisms, it can be modulated by phenotypic acclimation and/or genotypic adaptation, it depends on the ecological context of the host-pathogen-vector interactions, and it can be modulated by impacts of other stressors. As a consequence of this complexity, non-linear responses of disease sys- tems under climate change are to be expected. To improve predictions on climate change impacts on infectious disease, we sug- gest that more emphasis should be given to the integration of biomedical and ecological research for studying both the physio- logical and ecological mechanisms which mediate climate change impacts on disease, and to the development of harmonized methods and approaches to obtain more comparable results, as this would support the discrimination of case-specific versus gen- eral mechanisms .
文摘Introduction: The transmission of infectious agents through the hands of nursing staff during care is the main cause of nosocomial infections. Hand hygiene has been recognized for over a century as an effective measure to prevent healthcare associated infections in healthcare settings, the objective of this study was to appreciate the practice of hand hygiene during care by health professionals in the medical-surgical emergency department of the Donka National Hospital. Methods: It was a cross-sectional, analytical study. Data collection took place from March 1 to April 30, 2021. The study covered all health professionals, namely doctors, nurses, laboratory technicians, radiography technicians, pharmacists, students, stretcher bearers, surfactants who were present at the time of the study period. Results: During the study period, out of a total of 104 registered health professionals, we surveyed 99, which is a rate of 95%. The most represented age group was [30 - 39 years] with an average of 37.17 ± 10.34 years, and extremes of 22 years to 65 years. The male sex was the most dominant or 59.60% compared to the female sex or 40.40% with a sex ratio of 1.47. The hand hygiene compliance rate was low at 21%. The practice of hand hygiene during care for 100% of health professionals was very low, at 8.08%. No factors influence the observance of the practice of hand hygiene and the socio-professional characteristics of the conditions of provision of care activities. Conclusion: Hand hygiene during care is an essential aspect that must be considered as an essential measure in the prevention of infections in this period of the COVID-19 pandemic.
