Methods: A total of 118 children with recurrent respiratory tract infection who were treated in the hospital between January 2015 and January 2017 were collected and divided into control group and observation group by random number table method, 59 cases in each group. Control group received conventional therapy, and observation group received pidotimod combined with conventional therapy. The differences in serum levels of inflammatory mediators, acute phase proteins and Th1/Th2 cytokines were compared between the two groups before and after treatment. Results: Before treatment, the differences in serum levels of inflammatory mediators, acute phase proteins and Th1/Th2 cytokines were not statistically significant between the two groups. after 1 week of treatment, serum TNF-α, PCT, CRP, PAB, TRF and IL-4 contents of both groups of children were lower than those before treatment while IFN-γ contents as well as IFN-γ/ IL-4 levels were higher than those before treatment, and serum TNF-α, PCT, CRP, PAB, TRF and IL-4 contents of observation group were lower than those of control group while IFN-γ content as well as IFN-γ/ IL-4 level was higher than those of control group. Conclusion: Pidotimod combined with conventional drug therapy can effectively inhibit the infection status and optimize the Th1/Th2 cellular immune function of children with recurrent respiratory tract infection.展开更多

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

In this study, we evaluated the Qiagen ResPlex II V2.0 kit and explored factors influencing its sensitivity. Nasopharyngeal swab (NPS) specimens were prospectively collected from pediatric inpatients with lower respiratory tract infections at the time of admission in the Shenzhen Children's Hospital from May 2009 to April 2010. Total nucleic acids were extracted using the EZ1 system (Qiagen, Germany) and 17 respiratory viruses and genotypes including influenza A virus (FluA), FluB, parainfluenza virus 1 (PIV1), PIV2, PIV3, PIV4, respiratory syncytial virus (RSV), human metapneumovirus (hMPV), rhinoviruses (RhV), enteroviruses (EnV), human bocaviruses (hBoV), adenoviruses (AdV), four coronaviruses (229E, OC43, NL63 and HKU1), and FluA 2009 pandemic H1N1(H1N1-p) were detected and identified by the ResPlex II kit. In parallel, 16 real-time TaqMan quantitative RT-PCR assays were used to quantitatively detect each virus except for RhV. Influenza and parainfluenza viral cultures were also performed. Among the total 438 NPS specimens collected during the study period, one or more viral pathogens were detected in 274 (62.6%) and 201(45.9%) specimens by monoplex TaqMan RT-PCR and multiplex ResPlex, respectively. When results from monoplex PCR or cell culture were used as the reference standard, the multiplex PCR possessed specificities of 92.9-100.0%. The sensitivity of multiplex PCR for PIV3, hMPV, PIV1 and BoV were 73.1%, 70%, 66.7% and 55.6%, respectively, while low sensitivities (11.1%-40.0%) were observed for FluA, EnV, OC43, RSV and H1N1. Among the seven viruses/genotypes detected with higher frequencies, multiplex PCR sensitivities were correlated significantly with viral loads determined by the TaqMan RT-PCR in FluA, H1N1-p and RSV (p=0.011-0.000). The Qiagen ResPlex II multiplex RT-PCR kit possesses excellent specificity for simultaneous detection of 17 viral pathogens in NPS specimens in pediatric inpatients at the time of admission. The sensitivity of multiplex RT-PCR was influenced by viral loads, specimen process methods, primer and probe design and amplification condition.展开更多

Methods We conducted a semiparametric time-series analysis to estimate the percentage increase in emergency-room visits for RTI associated with changes in DTR after adjustment for daily weather conditions (temperature and relative humidity) and outdoor air pollution. Results DTR was significantly associated with daily emergency-room visits for RTI. An increase of 1 °C in the current-day (L0) and in the 2-day moving average (L01) DTR corresponded to a 0.94% [95% confidence interval (CI), 0.34%-1.55%] and 2.08% (95% CI, 1.24%-2.93%) increase in emergency-room visits for RTI, respectively. Conclusion DTR was associated with increased risk of RTI. More studies are needed to understand the impact of DTR on respiratory health.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

文摘Objective: To study the influence of pidotimod combined with conventional drug therapy on the infection status and immune function of children with recurrent respiratory tract infection. Methods: A total of 118 children with recurrent respiratory tract infection who were treated in the hospital between January 2015 and January 2017 were collected and divided into control group and observation group by random number table method, 59 cases in each group. Control group received conventional therapy, and observation group received pidotimod combined with conventional therapy. The differences in serum levels of inflammatory mediators, acute phase proteins and Th1/Th2 cytokines were compared between the two groups before and after treatment. Results: Before treatment, the differences in serum levels of inflammatory mediators, acute phase proteins and Th1/Th2 cytokines were not statistically significant between the two groups. after 1 week of treatment, serum TNF-α, PCT, CRP, PAB, TRF and IL-4 contents of both groups of children were lower than those before treatment while IFN-γ contents as well as IFN-γ/ IL-4 levels were higher than those before treatment, and serum TNF-α, PCT, CRP, PAB, TRF and IL-4 contents of observation group were lower than those of control group while IFN-γ content as well as IFN-γ/ IL-4 level was higher than those of control group. Conclusion: Pidotimod combined with conventional drug therapy can effectively inhibit the infection status and optimize the Th1/Th2 cellular immune function of children with recurrent respiratory tract infection.

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.

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 Recurrent respiratory tract infection (RRTI) is a disease occurred frequently in preschool children.Methods A total of 120 RRTI children were randomly divided into active group,remission group,intervention group and control group,meanwhile 30 healthy children were selected as the healthy group.Children in the intervention group were given oral Bifidobaeterium tetravaccine tablets (Live) for 2 months,while the control group received routine treatment.Stool sample were detected to analyze the bacterial strains.The occurrence of respiratory tract infection (RTI) was compared between different groups during 1 year follow-up.Results Compared with the healthy group,the number of Bifidobacteria and Lactobacilli in the active group,remission group,intervention group and control group was significantly decreased (P < 0.05).The number of Bifidobacteria and Lactobacilli in the intervention group was significantly higher compared to other RRTI groups (P < 0.05).During the follow-up period,the average annual frequency of different acute RTI and use of antibiotics were significantly reduced (P < 0.05),the average duration of cough,fever and use of antibiotics at each episode were also significantly shortened (P < 0.05) in the intervention group compared to the control group.Conclusions Children with RRTI are susceptible to intestinal flora imbalance.Oral probiotics can effectively improve the RRTI intestinal microecological balance in children and reduce the frequency of RTI.
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Importance:Recurrent respiratory tract infection(RRTI)is common in children.Inappropriate RRTI treatment will lead to asthma and other diseases,thereby seriously affecting the growth and physical health of children.Immune function modulation can prevent and alleviate childhood RRTI.Yupingfeng(YPF),a patented traditional Chinese medicine(TCM),has immunomodulatory effects and is widely used in China to treat children with RRTI.Objective:To evaluate the safety and efficacy of YPF monotherapy in treating children with RRTI.Methods:This multicenter,randomized,double-blind,double-simulation,noninferiority clinical trial was conducted from January 2015 to August 2017,with an 8-week treatment period and 52-week follow-up after the drug withdrawal.Children aged 2–6 years with RRTI meeting the inclusion and exclusion criteria were enrolled in 13 hospitals in China and divided randomly into three groups(2:2:1 ratio)to receive YPF,pidotimod,or placebo.The primary outcome was the proportion of RRTI returning to normal standard level during the follow-up.The secondary outcomes were reduction in the number of RRTI recurrences,effect on clinical symptoms(in accord with TCM practice),effect per symptom,and safety.The trial was registered at the Chinese Clinical Trials Registry(www.chictr.org.cn)under the unique identifier ChiCTR-IPR-15006847.Results:Three hundred and fifty-one children were enrolled and randomly assigned to 3 groups;124,125,and 61 children in the YPF,pidotimod,and placebo groups,respectively,had completed the trial.During the follow-up,the proportion of RRTI returning to normal standard level was 73.13%,67.15%,and 38.81%with YPF,pidotimod,and placebo,respectively(P<0.0001).The proportion of cases who returned to normal standard level in the YPF group was 34.32%higher than that in the placebo group.The safety profile did not significantly differ among the groups.Interpretation:YPF granules were noninferior to the active control drug pidotimod oral solution for the treatment of RRTI in children,and were superior to placebo,with a high safety profile.

文摘Objective:To explore the relationship between gastrointestinal heat retention syndrome and the incidence of pneumonia and recurrent respiratory tract infections(RRTIs)in children.Methods:A prospective cohort study was conducted in the pediatric outpatient department of Beijing Dongfang Hospital.Children without respiratory tract infections(RTIs)were consecutively recruited according to the selection criteria.A semi-structured questionnaire was used to record traditional Chinese medicine(TCM)symptoms and demographic and physiological characteristics.Gastrointestinal heat retention syndrome was considered to be a predisposing factor and was diagnosed according to a scale with reliability and validity.The participants were followed up for 12 months.Participants and their parents or guardians were contacted via clinical interviews and telephone every 6 months.Episodes of pneumonia and RTIs were recorded in detail.Results:A total of 420 children were included.Of participants,370(88.10%)were followed up for 12 months.The mean number of RTI episodes per participant was 5.37(95%CI:5.14 to 5.60).In total,186 participants in the gastrointestinal heat retention syndrome group and 184 participants in the nongastrointestinal heat retention syndrome group completed the 12-month follow-up period.The baseline of both groups was comparable.The incidence of RRTIs in children with gastrointestinal heat retention syndrome was 1.27(95%CI:1.01 to 1.59)times that in children without gastrointestinal heat retention syndrome.Logistic regression analysis revealed that abnormally increased appetite with frequent hunger,foul breath,dry stools,and dark red or purple fingerprints were positively correlated with the incidence of pneumonia.Irascibility and feverish feelings in the palms and soles were positively correlated with the occurrence of RRTI.Conclusions:Gastrointestinal heat retention syndrome is a risk factor for RRTIs in children.Studies with larger sample sizes and longer follow-up time are warranted to confirm the degree of causal risk associated with RTIs.
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Multiplex RT-PCR assays have been widely used tools for detection and differentiation of a panel of respiratory viral pathogens. In this study, we evaluated the Qiagen ResPlex II V2.0 kit and explored factors influencing its sensitivity. Nasopharyngeal swab (NPS) specimens were prospectively collected from pediatric inpatients with lower respiratory tract infections at the time of admission in the Shenzhen Children's Hospital from May 2009 to April 2010. Total nucleic acids were extracted using the EZ1 system (Qiagen, Germany) and 17 respiratory viruses and genotypes including influenza A virus (FluA), FluB, parainfluenza virus 1 (PIV1), PIV2, PIV3, PIV4, respiratory syncytial virus (RSV), human metapneumovirus (hMPV), rhinoviruses (RhV), enteroviruses (EnV), human bocaviruses (hBoV), adenoviruses (AdV), four coronaviruses (229E, OC43, NL63 and HKU1), and FluA 2009 pandemic H1N1(H1N1-p) were detected and identified by the ResPlex II kit. In parallel, 16 real-time TaqMan quantitative RT-PCR assays were used to quantitatively detect each virus except for RhV. Influenza and parainfluenza viral cultures were also performed. Among the total 438 NPS specimens collected during the study period, one or more viral pathogens were detected in 274 (62.6%) and 201(45.9%) specimens by monoplex TaqMan RT-PCR and multiplex ResPlex, respectively. When results from monoplex PCR or cell culture were used as the reference standard, the multiplex PCR possessed specificities of 92.9-100.0%. The sensitivity of multiplex PCR for PIV3, hMPV, PIV1 and BoV were 73.1%, 70%, 66.7% and 55.6%, respectively, while low sensitivities (11.1%-40.0%) were observed for FluA, EnV, OC43, RSV and H1N1. Among the seven viruses/genotypes detected with higher frequencies, multiplex PCR sensitivities were correlated significantly with viral loads determined by the TaqMan RT-PCR in FluA, H1N1-p and RSV (p=0.011-0.000). The Qiagen ResPlex II multiplex RT-PCR kit possesses excellent specificity for simultaneous detection of 17 viral pathogens in NPS specimens in pediatric inpatients at the time of admission. The sensitivity of multiplex RT-PCR was influenced by viral loads, specimen process methods, primer and probe design and amplification condition.

文摘Objective This study aimed to assess the association between emergency-room visits for respiratory tract infection (RTI) with diurnal temperature range (DTR), a weather parameter closely associated with urbanization and global climate change. Methods We conducted a semiparametric time-series analysis to estimate the percentage increase in emergency-room visits for RTI associated with changes in DTR after adjustment for daily weather conditions (temperature and relative humidity) and outdoor air pollution. Results DTR was significantly associated with daily emergency-room visits for RTI. An increase of 1 °C in the current-day (L0) and in the 2-day moving average (L01) DTR corresponded to a 0.94% [95% confidence interval (CI), 0.34%-1.55%] and 2.08% (95% CI, 1.24%-2.93%) increase in emergency-room visits for RTI, respectively. Conclusion DTR was associated with increased risk of RTI. More studies are needed to understand the impact of DTR on respiratory health.
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.
