Objectives: To identify how prevalent Streptococcus pyogenes is among Umrah visitors and pilgrims by comparing its presence before and after the visitors perform Umrah and hajj. Methods: A cross-sectional study was carried out on Umrah visitors/pilgrims, for which their throat swabs were taken for assessing the upper respiratory tract infection’s carriage rate, particularly of Group A streptococci (GAS), after they arrived in Saudi Arabia for the Hajj and Umrah rituals and befor their leaving. After collecting the swabs, they were inoculated on Columbia agar using 5% sheep blood and then incubated at 37˚C. VITEK 2 systems were used to identify the isolates. Results: Of the 979/613 Umrah visitors/pilgrims involved, before performing Umrah, their Streptococcus pyogenes percentage was 0.2% and it increased to 0.7 after performing Umrah. Further, the Streptococcus pyogenes percentage before and after performing Hajj was 0.3% and 1.1%, respectively. No statistical significance was found in the difference between the positive Streptococcus pyogenes found before and after performing Hajj and Umrah among Umrah visitors/pilgrims (p-value = 0.2). All bacterial isolates were found to be sensitive to Cefotaxime and Ceftriaxone antibiotics (100%). Conclusion: The Streptococcus pyogeneshigh resistance to antibiotics combined with the lack of a vaccine poses a serious risk concerning the resulting infection spread and emphasizes the necessity of ensuring greater global surveillance of such epidemics.展开更多

Methods: In this observational and cross-sectional analysis, 114 patients admitted in the intensive care unit were enrolled. The endotracheal aspirates and bronchoalveolar lavage were collected. The bacteria were isolated and identified, and finally, antimicrobial sensitive pattern of the isolated bacteria was examined. Results: The prevalence of infection was 72.72% in male patients and 27.28% in females. The predominant bacteria were Klebsiella pneumoniae (37.50%) followed by Acinetobacter spp. (36.36%), Pseudomonas aeruginosa (7.95%),Escherichia coli (6.81%), Proteus mirabilis (2.27%), atypical Escherichia coli (1.13%), Enterococcus spp. (1.13%),Elizabethkingia meningoseptica (1.13%),Staphylococcus aureus (1.13%),Proteus vulgaris (1.13%), Citrobacter freundii (1.13%), and Citrobacter koseri (1.13%). High resistance to cephalosporins (82.18%) was demonstrated in all Gram-negative bacteria. Bacteria showed susceptibility to colistin (88.75%) followed by tigecycline (83.11%), gentamycin (36.18%), and amikacin (49.23%). Conclusions: As the most frequent respiratory organisms, Klebsiella pneumoniae and Acinetobacter spp. have increased resistance to cephalosporins and susceptibility to colistin followed by tigecycline.展开更多

The objectives are 1) to report the prevalence of antihistamine prescription for children less than 6 years old with acute upper respiratory infection and 2) to explore the associated factors for the prescription practice.METHODS: This is a cross-sectional study. All consecutive cases of paediatric patients aged 6 or below who presented to the emergency department during a study period of one week from April 1 to July 4, 2009 with diagnosis of acute upper respiratory infection were included. Totally 162 patients were included.RESULTS: Among the 162 cases, 141(87%) patients were prescribed one antihistamine of any group. Sixty(37%) patients were prescribed two or more antihistamines. In multivariate logistic regression model, age was found to be signi? cantly(P<0.001) associated with multiple antihistamine prescription(OR=1.042, 95%CI=1.02 to 1.06). Years of graduation of attending physician for more than 5 years was also a strong predictor of multiple antihistamine prescription(OR=4.654, 95%CI=2.20 to 9.84, P<0.001).CONCLUSION: In the local emergency department, patients' age and the years of graduation from medical school of the attending physician were predictors of multiple antihistamine prescription for acute upper respiratory infections for children aged less than 6.展开更多

These causes include general anesthesia, intubation factors, factors inherent to the patient, surgical factors, the injudicious use of antimicrobial agents, and the environmental factors of the ward. The perioperative management of the respiratory tract should be strengthened. Health education, respiratory function training, oral nursing intervention,atomization inhalation, and personalized expectoration methods should receive more attention to decrease the complications and promote the early rehabilitation of patients after abdominal surgery.展开更多

文摘Objective Human adenovirus(HAdV)infection is common and can develop to serious conditions with high mortality,yet the mechanism of HAdV infection remains unclear.In the present study,the serum metabolite profiles of HAdV-7-infected patients with pneumonia or upper respiratory tract infection(URTI)were explored.Methods In total,35 patients were enrolled in the study following an outbreak of HAdV-7 in the army,of whom 14 had pneumonia and 21 had URTI.Blood samples were collected at the acute stage and at the recovery stage and were analyzed by untargeted metabolomics.Results Over 90% of the differential metabolites identified between the pneumonia patients and URTI patients were lipids and lipid-like molecules,including glycerophospholipids,fatty acyls,and sphingolipids.The metabolic pathways that were significantly enriched were primarily the lipid metabolism pathways,including sphingolipid metabolism,glycerophospholipid metabolism,and linoleic acid metabolism.The sphingolipid metabolism was identified as a significantly differential pathway between the pneumonia patients and URTI patients and between the acute and recovery stages for the pneumonia patients,but not between the acute and recovery stages for the URTI patients.Ceramide and lactosylceramide,involved in sphingolipid metabolism,were significantly higher in the pneumonia patients than in the URTI patients with good discrimination abilities[area under curve(AUC)0.742 and 0.716,respectively;combination AUC 0.801].Conclusion Our results suggested that HAdV modulated lipid metabolism for both the patients with URTI and pneumonia,especially the sphingolipid metabolism involving ceramide and lactosylceramide,which might thus be a potential intervention target in the treatment of HAdV infection.

文摘Objective:This study aims to explore the prevalence,features,and risk factors of lower respiratory tract infections(LRTIs)in the intensive care unit(ICU)of a newly established hospital in Zunyi City.The goal is to devise strategies for preventing LRTIs in the ICU of new hospitals,thereby mitigating the incidence of nosocomial LRTIs in ICU patients.Methods:A case-control study was conducted from March 2019 to December 2022 to investigate the incidence rate of LRTIs in the ICU of a newly constructed hospital in Zunyi City.Patients with LRTIs constituted the case group,while those without LRTIs constituted the control group,where a 1:1 matching principle was adhered to.A single-factor chi-square(χ2)test was employed to analyze the risk factors,with independent risk factors being explored using a multivariate logistic regression analysis.Results:A total of 169 strains of pathogenic bacteria were isolated,comprising 66.28%gram-negative bacteria,17.75%gram-positive bacteria,and 15.97%fungi.The most prevalent pathogens included Acinetobacter baumannii(43.20%),Candida albicans(10.65%),and Pseudomonas aeruginosa(8.88%).Of the 82 strains infected by multidrug-resistant bacteria in patients with LRTIs,81.7%were carbapenem-resistant Acinetobacter baumannii,9.8%were multidrug-resistant Pseudomonas aeruginosa,and 6.1%were carbapenem-resistant Escherichia coli.Identified risk factors included smoking history,total hospitalization days,ICU stay length,hypoproteinemia,indwelling gastric tube,intubation type,duration of mechanical ventilation,usage of antibacterial drugs,and administration of protein drugs(P<0.05).Multivariate logistic regression analysis demonstrated that these factors were independent risk factors for nosocomial LRTIs in ICU patients(P<0.05).Conclusion:ICU patients in our hospital were mainly infected by carbapenem-resistant Acinetobacter baumannii.To prevent LRTIs in patients,tailored preventive measures should be developed and the rational use of antibacterial drugs should be promoted.
文摘Background: Respiratory tract infection (RTI) is a prevalent infection across the world and is a major health concern linked to the crowding that occurs during the Hajj season. Objectives: To identify how prevalent Streptococcus pyogenes is among Umrah visitors and pilgrims by comparing its presence before and after the visitors perform Umrah and hajj. Methods: A cross-sectional study was carried out on Umrah visitors/pilgrims, for which their throat swabs were taken for assessing the upper respiratory tract infection’s carriage rate, particularly of Group A streptococci (GAS), after they arrived in Saudi Arabia for the Hajj and Umrah rituals and befor their leaving. After collecting the swabs, they were inoculated on Columbia agar using 5% sheep blood and then incubated at 37˚C. VITEK 2 systems were used to identify the isolates. Results: Of the 979/613 Umrah visitors/pilgrims involved, before performing Umrah, their Streptococcus pyogenes percentage was 0.2% and it increased to 0.7 after performing Umrah. Further, the Streptococcus pyogenes percentage before and after performing Hajj was 0.3% and 1.1%, respectively. No statistical significance was found in the difference between the positive Streptococcus pyogenes found before and after performing Hajj and Umrah among Umrah visitors/pilgrims (p-value = 0.2). All bacterial isolates were found to be sensitive to Cefotaxime and Ceftriaxone antibiotics (100%). Conclusion: The Streptococcus pyogeneshigh resistance to antibiotics combined with the lack of a vaccine poses a serious risk concerning the resulting infection spread and emphasizes the necessity of ensuring greater global surveillance of such epidemics.
文摘Objective: To investigate the application of WBC, CRP and SAA combined detection in the early diagnosis of respiratory tract infection in children. Methods: Collect the literature reports on the early diagnosis of respiratory tract infection in children by the combined detection of WBC, CRP and SAA in recent years, and follow up the relevant literature reports from the selection of “new three routine” laboratory items for rapid diagnosis in pediatric outpatient department and the application of the combined detection of WBC, CRP and SAA in the early diagnosis of respiratory tract infection in children. Results: Many literature studies found that the combined detection of WBC, CRP and SAA has important clinical significance in the early diagnosis of respiratory tract infection in children. Conclusion: Through reviewing the relevant literature, we can understand the application of WBC, CRP and SAA combined detection in the early diagnosis of respiratory tract infection in children. To provide more accurate and reliable laboratory data for the early diagnosis and treatment of respiratory tract infection in children in the future.
文摘Background:The effectiveness of vitamin C in the prevention and treatment of pediatric upper respiratory tract infections was evaluated in a meta-analysis.Methods:A total 2,573 children with upper respiratory tract infections were included in the meta-analysis,1,280 of whom received vitamin C and 1,293 who received control medication.The analysis of findings related to the studies included was done through random or fixed effects model to determine whether vitamin C supplementation could stop and control upper respiratory tract infections in children using mean difference(MD)with 95%confidence intervals(CIs).Results:On average,vitamin C-treated children had fewer upper respiratory tract infection bouts,their illness lasted shorter(MD-0.84;95%CI-1.47 to-0.20,P=0.009),and they were less contagious than the control.Conclusions:The number of episodes and illness duration of upper respiratory tract-infected pediatric subjects were considerably reduced in the intervention group(vitamin C)compared to the control.Due to the small sample size in four of 11 studies and the limited number of studies included for comparison,the outcomes should be carefully examined.
文摘Objective:To explore and analyze the clinical effect of comfort nursing on children with acute otitis media.Methods:62 children with acute otitis media caused by upper respiratory tract infection who visited the outpatient clinic of our hospital from June 2022 to June 2023 were selected for this study.They were divided into a study group(n=31)and a control group(n=31).Children in the control group received basic care,while children in the study group received comfort nursing along with basic care.The hearing thresholds,body temperature,treatment compliance,and nursing satisfaction of the two groups of children were compared.Results:After the nursing intervention,the hearing threshold and average body temperature of the children in the study group were lower than those in the control group(P<0.05);the treatment compliance of the children in the study group was higher than that in the control group(P<0.05);the nursing satisfaction of the study group was higher than that of the control group(P<0.05).Conclusion:Comfort nursing can improve the treatment effect,treatment compliance,and nursing satisfaction of children with children with acute otitis media caused by upper respiratory tract infection.
文摘BACKGROUND Respiratory tract infections in the elderly are difficult to cure and can easily recur,thereby posing a great threat to patient prognosis and quality of life.AIM To investigate the therapeutic effects of different antibiotics in elderly patients with respiratory tract infection.METHODS Seventy-four elderly patients with respiratory tract infection were randomly allocated to a study(n=37;treated with cefoperazone sodium/sulbactam sodium)or control(n=37;treated with piperacillin sodium/tazobactam sodium on the basis of routine symptomatic support)group.Both groups were treated for 7 d.Time to symptom relief(leukocyte recovery;body temperature recovery;cough and sputum disappearance;and rale disappearance time),treatment effect,and laboratory indexes[procalcitonin(PCT),C-reactive protein(CRP),white blood cell count(WBC),and neutrophil percentage(NE)]before and 7 d after treatment and the incidence of adverse reactions were assessed.RESULTS In the study group,the time to WBC normalization(6.79±2.09 d),time to body temperature normalization(4.15±1.08 d),time to disappearance of cough and sputum(6.19±1.56 d),and time to disappearance of rales(6.68±1.43 d)were shorter than those of the control group(8.89±2.32 d,5.81±1.33 d,8.77±2.11 d,and 8.69±2.12 d,respectively;P=0.000).Total effective rate was higher in the study group(94.59%vs 75.68%,P=0.022).Serum PCT(12.89±3.96μg/L),CRP(19.62±6.44 mg/L),WBC(20.61±6.38×10^(9)/L),and NE(86.14±7.21%)levels of the study group before treatment were similar to those of the control group(14.05±4.11μg/L,18.79±5.96 mg/L,21.21±5.59×10^(9)/L,and 84.39±6.95%,respectively)with no significant differences(P=0.220,0.567,0.668,and 0.291,respectively).After 7 d of treatment,serum PCT,CRP,WBC,and NE levels in the two groups were lower than those before treatment.Serum PCT(2.01±0.56μg/L),CRP(3.11±1.02 mg/L),WBC(5.10±1.83×10^(9)/L),and NE(56.35±7.17%)levels were lower in the study group than in the control group(3.29±0.64μg/L,5.67±1.23 mg/L,8.13±3.01×10^(9)/L,and 64.22±8.08%,respectively;P=0.000).There was no significant difference in the incidence of adverse reactions between the groups(7.50%vs 12.50%,P=0.708).CONCLUSION Piperacillin sodium/tazobactam sodium is superior to cefoperazone sodium/sulbactam sodium in the treatment of elderly patients with respiratory tract infection with a similar safety profile.
文摘Objective: To investigate the prevalence of isolated organisms in patients with lower respiratory tract infections and the antibiotic susceptibilities at a tertiary care center. Methods: In this observational and cross-sectional analysis, 114 patients admitted in the intensive care unit were enrolled. The endotracheal aspirates and bronchoalveolar lavage were collected. The bacteria were isolated and identified, and finally, antimicrobial sensitive pattern of the isolated bacteria was examined. Results: The prevalence of infection was 72.72% in male patients and 27.28% in females. The predominant bacteria were Klebsiella pneumoniae (37.50%) followed by Acinetobacter spp. (36.36%), Pseudomonas aeruginosa (7.95%),Escherichia coli (6.81%), Proteus mirabilis (2.27%), atypical Escherichia coli (1.13%), Enterococcus spp. (1.13%),Elizabethkingia meningoseptica (1.13%),Staphylococcus aureus (1.13%),Proteus vulgaris (1.13%), Citrobacter freundii (1.13%), and Citrobacter koseri (1.13%). High resistance to cephalosporins (82.18%) was demonstrated in all Gram-negative bacteria. Bacteria showed susceptibility to colistin (88.75%) followed by tigecycline (83.11%), gentamycin (36.18%), and amikacin (49.23%). Conclusions: As the most frequent respiratory organisms, Klebsiella pneumoniae and Acinetobacter spp. have increased resistance to cephalosporins and susceptibility to colistin followed by tigecycline.
文摘BACKGROUND: Currently there is very limited data in the literature assessing the prevalence of antihistamine prescription, and there is no local prevalence data about the prescription of antihistamine agents among primary practitioner and emergency physicians. The objectives are 1) to report the prevalence of antihistamine prescription for children less than 6 years old with acute upper respiratory infection and 2) to explore the associated factors for the prescription practice.METHODS: This is a cross-sectional study. All consecutive cases of paediatric patients aged 6 or below who presented to the emergency department during a study period of one week from April 1 to July 4, 2009 with diagnosis of acute upper respiratory infection were included. Totally 162 patients were included.RESULTS: Among the 162 cases, 141(87%) patients were prescribed one antihistamine of any group. Sixty(37%) patients were prescribed two or more antihistamines. In multivariate logistic regression model, age was found to be signi? cantly(P<0.001) associated with multiple antihistamine prescription(OR=1.042, 95%CI=1.02 to 1.06). Years of graduation of attending physician for more than 5 years was also a strong predictor of multiple antihistamine prescription(OR=4.654, 95%CI=2.20 to 9.84, P<0.001).CONCLUSION: In the local emergency department, patients' age and the years of graduation from medical school of the attending physician were predictors of multiple antihistamine prescription for acute upper respiratory infections for children aged less than 6.
文摘This article provides a review of the causes of respiratory tract infection after abdominal surgery. These causes include general anesthesia, intubation factors, factors inherent to the patient, surgical factors, the injudicious use of antimicrobial agents, and the environmental factors of the ward. The perioperative management of the respiratory tract should be strengthened. Health education, respiratory function training, oral nursing intervention,atomization inhalation, and personalized expectoration methods should receive more attention to decrease the complications and promote the early rehabilitation of patients after abdominal surgery.

文摘Objective To explore the prescribing patterns of outpatients receiving antibiotics for upper respiratory tract infections(URTIs)in rural Western China and to identify the correlation in terms of doctors and patients characteristics.Methods Totally 7 678 prescriptions for URTIs were collected from 680 primary health village clinics of 40 counties across 10 provinces of Western China.Two outcome variables were used in the analysis:the occurrence of prescribing at least one antibiotic drug for an URTI and the occurrence of prescribing two or more antibiotics for an URTI.GEE logistic regression models were used to examine the socioeconomic and demographic determinants of the above two outcome variables.Results The percentage of prescribing at least one antibiotic for URTIs was 48.6% while the percentage of prescribing antibiotic combination(two or more antibiotics)was 4.6%.The two measurements of antibiotic utilization differed remarkably among the 10 provinces.Patients diagnosed with tonsillitis and faucitis had higher odds(OR=8.86 for tonsillitis and OR=4.64 for faucitis)of antibiotic prescription than patients with other diagnosis of URTIs.Patients with tonsillitis and faucitis also had higher odds(OR=3.82 for tonsillitis and OR=2.71 for faucitis)of multiple antibiotic prescription than those with other diagnosis of URTIs.The number of drugs per prescription and injection in prescriptions were also significant predictors of antibiotic and multiple antibiotic utilization for URTIs.Conclusion It is concluded that the percentage of antibiotic prescription for URTIs is higher in rural Western China than in most of other countries with available data and that prescriptions of antibiotics for URTIs are associated with residence regions of patients,URTI diagnosis and background information on drug prescription.
文摘Objective:To examine the effects of human bocavirus type 1(HBoV1)on the course of lower respiratory tract infections in cases of monoinfection and coinfection,and the effects of HBoV1 viral load on the disease in children under six years old hospitalized with a diagnosis of HBoV1-associated lower respiratory tract infections.Methods:Children under six years of age,who were hospitalized with the diagnosis of lower respiratory tract infection due to HBoV1 between 1 January 2021 and 1 January 2022 were included in the study.Laboratory confirmation of the respiratory pathogens was performed using polymerase chain reaction(PCR).Results:Fifty-four(16.4%)children with HBoV1 among 329 children whose PCR was positive with bacterial/viral agent in nasopharyngeal swab samples were included in the study.There were 28(51.9%)males and 26(48.1%)females with a median age 23.4 months[interquartile range(IQR):13.2,30.0 months](min-max:1 month-68 months).HBoV1 was detected as a monoinfecton in 26(48.1%)children,and as a coinfection with other respiratory agents in 28 children(51.9%).In multiple regression analysis,coinfection(P=0.032)was associated with the length of hospitalization(P<0.001;R^(2)=0.166).There was a negative correlation(r=−0.281,P=0.040)between cough and cycle threshold.Fever was found to be positively correlated with C-reactive protein(r=0.568,P<0.001)and procalcitonin(r=0.472;P=0.001).Conclusions:Although we found a higher HBoV1 viral load in children with more cough symptoms in our study,it had no effect on the severity of the disease,such as length of hospital stay and need for intensive care.Coinfection was found to affect the length of hospitalization.

文摘Objective:Gastrointestinal heat retention syndrome(GHRS)is associated with lung-heat syndrome and is related to recurrent respiratory infection.Upper respiratory tract infection(URTI)lung heat syndrome is common in children.The study will explore the effect of GHRS on the structure and function of gut microbiota in children with URTI lung-heat syndrome.Methods:Participants were divided into both groups using the self-developed URTI scale and the“GHRS Diagnostic Scale$Pediatric Part”:GHRS-positive children(LS group)and GHRS-negative children(L group).General information,clinical symptoms,and stool were collected.We used 16S rRNA amplicon sequencing technology to determine the gene sequence of the V3eV4 region in feces and measure the gut microbiota of the both groups at the genus level.Results:A total of 23 children were included in the both groups.There were 12 cases in the LS group and 11 cases in the L group.There was no statistical difference between the both groups in age,gender,height,weight,and body mass index.The effective sequences shared by the both groups accounted for 85.66%of the total.In the gut microbiota,there was no difference in the a diversity and the b diversity between the both groups.Compared with the L group,the LS group had a significant increase in the relative abundance of the Ruminococcus gnavus group,Prevotella-9,Staphylococcus,and Actinomyces(P<.05).The functions of the both groups of microbiota primarily concentrate on metabolism,genetic information processing,and environmental information processing.The relative abundance of signaling molecules and interactions in the LS group were higher than that in the L group(P<.05).The redundancy analysis(RDA)showed that the URTI score had the greatest impact on the distribution of microbiota.Conclusion:GHRS may affect the development of URTI lung-heat syndrome by changing the relative abundances of gut microbiota.
