Plasma Metabonomics of Human Adenovirus-infected Patients with Pneumonia and Upper Respiratory Tract Infection

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.

A Meta-Analysis of the Effectiveness of Vitamin C in the Prevention and Treatment of Childhood Upper Respiratory Tract Infections

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.

The Effect of Comfort Nursing on the Compliance and Efficacy of Treatment for Children with Acute Otitis Media Caused by Upper Respiratory Tract Infection

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.

An association between Helicobacter pylori and upper respiratory tract disease: Fact or fiction?

Helicobacter pylori(H. pylori) is a major cause of chronic gastritis and gastric ulcers and considerable evidence supports the notion that infection with this bacterium is also associated with gastric malignancy in addition to various other conditions including pulmonary, vascular and autoimmune disorders. Gastric juice infected with H. pylori might play an important role in upper respiratory tract infection. Although direct and/or indirect mechanisms might be involved in the association between H. pylori and upper respiratory tract diseases, the etiological role of H. pylori in upper respiratory tract disorders has not yet been fully elucidated. Although various studies over the past two decades have suggested a relationship between H. pylori and upper respiratory tract diseases, the findings are inconsistent. The present overview describes the outcomes of recent investigations into the impact of H. pylori on upper respiratory tract and adjacent lesions.

Prescription practice of antihistamines for acute upper respiratory tract infections in pediatric patients in a local emergency department in Hong Kong

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.

Antibiotic prescribing patterns for upper respiratory tract infections in rural Western China

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.

Novel Approach to Microbiological Study of Chronic Inflammations at Upper Respiratory Tract: Research of Blood L-Form Microbiota

Background: The recognition of human blood microbiota, consisting of cell wall-deficient microbes (L-forms), is a major challenge today in the field of microbiology. There are accumulating data confirming the concept of “internal” blood L-form microbiota and its significance for health and diseases. Finding out whether the blood microbiota can be of diagnostic and prognostic importance for detection and evaluation of chronic infections anywhere in the body is a major objective. In the context of chronically infected upper respiratory tract (URT), the aim of the current study was to understand whether a local infection can be a source for entry of bacteria and fungi in the blood. Methods: Blood samples from six persons with chronic inflammations in URT diagnosed with hypertrophied adenoids, chronic sinusitis, nasal polyps, chronic naso-pharyngitis and one control healthy person were studied. Blood microbiota assessment methodology that be used, included three phases: 1) isolation of L-form cultures from blood-development and propagation;2) cultivation directed to conversion of L-forms into bacterial and fungal cultures;3) isolation of pure classical bacterial and fungal cultures and their identification by MALDI-TOF method. Results: From the patients were isolated L-forms of opportunistic bacteria (Streptococcus mitis, Roseomonas mucosa, Dermacoccus nishinomiyaensis, Enterococcus faecalis, Acinetobacter johnsonii, Pseudomonas putida, Staphylococcus aureus, Pseudomonas luteola, Enterobacter cloacae) and fungi such as Rhodotorula mucilaginosa, Aspergillus niger, Aspergillus fumigatus and Mucorales. Conclusion: The novel innovative methodology for assessment of blood L-form microbiota was successfully applied for detection of microbes responsible for chronic infections at URT.

Effectiveness and Safety of Jinye Baidu Granules(金叶败毒颗粒)for Acute Upper Respiratory Tract Infection:A Systematic Review and Meta-analysis

To evaluate the effectiveness and safety of Jinye Baidu Granules(金叶败毒颗粒)for acute upper respiratory tract infection(AURTI).Database such as CNKI,Wan-fang,VIP,Sino Med,Web of science,Clinical Trials gov,Medline、EMBASE,CENTRAL,Cochrane Library were retrieved to collect randomized controlled trials(RCTs)on Jinye Baidu Granules(金叶败毒颗粒)in treating AURTI from the estabslishment of the database to March 2019.A total of 2 reviewers independently screened the literature according to the inclusion and exclusion criteria,and extracted material and the quality evaluation of the included studies.Quality evaluation adopted Cochrane Handbook 5.1 evaluation standards and tools.Rev Man5.3 was used to perform Meta-analysis for the adopted study.Finally a total of 4 RCTs involving 636 patients were included.Meta-analysis results showed that:compared with conventional Western medicine alone,Jinye Baidu Granules(金叶败毒颗粒)combined with Western medicine in the treatment of acute upper respiratory tract infection can improve the total effective rate of clinical efficacy[RR=0.13,95%CI(0.06,0.29),P<0.00001],shorten the time of antipyretic time for acute upper respiratory tract infection[MD=–1.22,95%CI(–1.43,–1.00),P<0.00001],shorten the time of pharyngeal pain[MD=–1.97,95%CI(–2.97,–0.96),P<0.0001]and shorten the cough disappear time[MD=–1.97,95%CI(–2.97,–0.96),P<0.0001].There were 2 papers reporting adverse reactions during the study period,and one of them specifically reported diarrhea,nausea,vomiting and stomachache in the experimental group.In the control group:diarrhea,nausea and adverse reactions disappeared after drug withdrawal;the incidence of adverse reactions was 3.92%in the control group and 5.88%in the observation group.There was no significant difference between the 2 groups(P>0.05).Based on existing data and methods,the systematic evaluation showed that,compared with Western medicine alone,Jinye Baidu Granules(金叶败毒颗粒)combined with Western medicine alone could improve the total effective rate of clinical efficacy,reduce the time of fever,sore throat,and the disappearance of cough with less adverse reactions.However,due to the low quality of the included study,large samples,multicenter,randomized,double-blind trials and trials are still needed to randomized controlled trials with reference to the CONSORT standard and the STRICTA statement.

Effects of cartilaginous rings on airflow and particle transport through simplified and realistic models of human upper respiratory tracts

In the present study, computational fluid dynamics （CFD） is used to investigate inspiratory and expiratory airflow characteristics in the human upper respiratory tract for the purpose of identifying the probable locations of particle deposition and the wall injury. Computed tomography （CT） scan data was used to reconstruct a three dimensional respiratory tract from trachea to first generation bronchi. To compare, a simplified model of respiratory tract based on Weibel was also used in the study. The steady state results are obtained for an airflow rate of 45 L/min, corresponding to the heavy breathing condition. The velocity distribution, wall shear stress, static pressure and particle deposition are compared for inspiratory flows in simplified and realistic models and expiratory flows in realistic model only. The results show that the location of cartilaginous rings is susceptible to wall injury and local particle deposition.

Effect of gastrointestinal heat retention syndrome on gut microbiota in children with upper respiratory tract infection and lung-heat syndrome

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.

Traditional Chinese Medicine Nursing Protocols for Fever Caused by Exogenous Pathogens (Upper Respiratory Infection)

Fever caused by exogenous pathogens,also called upper respiratory infection( URI),refers to a classification of exogenous diseases induced by invasion of six pathogenic factors into the body leading to disharmony betw een nutrient Qi and defensive Qi and imbalance of Yin and Yang. As an extremely common symptom or sign,it is frequently seen in various processes of acute and chronic diseases. In recent years,traditional Chinese medicine( TCM) has achieved a certain efficacy in the treatment of fever caused by exogenous pathogens,such as modified formulae,Chinese patent drugs,self-made formulae,acupuncture,moxibustion and so on.This article mainly explored the key points of common syndromes,TCM nursing methods and health guidance of fever caused by exogenous pathogens,in order to further develop the advantages of TCM,improve its efficacy and standardize its nursing behavior.

SARS-CoV-2 viral load in the upper respiratory tract and disease severity in COVID-19 patients

Due to the disease's broad clinical spectrum,it is currently unclear how to predict the future prognosis of patients at the time of diagnosis of coronavirus disease 2019(COVID-19).Real-time reverse transcription-polymerase chain reaction(RTPCR)is the gold standard molecular technique for diagnosing COVID-19.The number of amplification cycles necessary for the target genes to surpass a threshold level is represented by the RT-PCR cycle threshold(Ct)values.Ct values were thought to be an adequate proxy for severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)viral load.A body of evidence suggests that SARS-CoV-2 viral load is a possible predictor of COVID-19 severity.The link between SARS-CoV-2 viral load and the likelihood of severe disease development in COVID-19 patients is not clearly elucidated.In this review,we describe the scientific data as well as the important findings from many clinical studies globally,emphasizing how viral load may be related to disease severity in COVID-19 patients.Most of the evidence points to the association of SARS-CoV-2 viral load and disease severity in these patients,and early anti-viral treatment will reduce the severe clinical outcomes.

We made clinical observations on the therapeutic effect of acupuncture on acute upper respiratory tract infection and compared with the effect of paracetamol and Antondine, The result showed that acupuncture therapy could allay fever more rapidly than drugs, so long as the differentiation of syndromes is correct and the acupoint is selected properly.

Discordance between olfactory psychophysical measurements and olfactory event related potentials in five patients with olfactory dysfunction following upper respiratory infection

Background Subjective olfactory tests are easy to perform and popularly applied in the clinic, but using only these, it is difficult to diagnose all disorders of the olfactory system. The olfactory event related potentials technique offers further insight into the olfactory system and is an ideal objective test. This analysis was of subjective and objective data on the olfactory function of twelve patients with loss of smell associated with an upper respiratory infection （URI）. Methods We tested the twelve patients with URI induced olfactory loss by medical history, physical examination of the head and neck, olfactory tests and medical imaging. Olfactory function was assessed by Toyota and Takagi olfactometry including olfactory detection and recognition thresholds and olfactory event-related potentials （OERPs） recorded with OEP-98C Olfactometer. Results An unusual phenomenon was observed in five patients in whom the subjective detection and recognition thresholds were normal, while the expected OERPs were not detectable. Conclusions We suggest that the discordance between olfactory psychophysical measurements and OERPs might be the results of abnormal electrophysiology related with olfactory neuropathy caused by viral URI. In addition, the measurement of OERPs might play a significant role in evaluating olfactory dysfunction.

Progressive deterioration of the upper respiratory tract and the gut microbiomes in children during the early infection stages of COVID-19

Children are less susceptible to coronavirus disease 2019 (COVID-19), and they have manifested lower morbidity and mortality after infection, for which a multitude of mechanisms may be considered. Whether the normal development of the gut-airway microbiome in children is affected by COVID-19 has not been evaluated. Here, we demonstrate that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)infection alters the upper respiratory tract and the gut microbiomes in nine children. The alteration of the microbiome is dominated by the genus Pseudomonas, and it sustains for up to 25e58 days in different individuals. Moreover, the patterns of alternation are different between the upper respiratory tract and the gut. Longitudinal investigation shows that the upper respiratory tract and the gut microbiomes are extremely variable among children during the course of COVID-19. The dysbiosis of microbiome persists in7 of 8 children for at least 19e24 days after discharge from the hospital. Disturbed development of both the gut and the upper respiratory microbiomes and prolonged dysbiosis in these nine children imply possible long-term complications after clinical recovery from COVID-19, such as predisposition to the increased health risk in the post-COVID-19 era.

Clinical practices s of Traditional Chinese Medicine for acute upper respiratory tract infection in children

OBJECTIVE:To develop Clinical practice s of Traditional Chinese Medicine(TCM) for acute upper respiratory tract infection(AURI) in children;TCM is usedalone or administered together with antibiotics.METHODS:Under the guidance of evidence-based medicine concept,in strict accordance with the rules of international s development,as well as on the basis of evidence of clinical research of TCM,the s solicited opinions from clinical experts and methodologists in TCM and Western Medicine.GRADE standard was applied to form experts' consensus.RESULTS:The s standardized classification of TCM patterns and TCM treatments in children with AURI,including prescription,Chinese patent medicine,non-drug treatment and prevention.CONCLUSION:Follows the principle of "evidence based,consensus supplemented,and experience referred",these s were formulated,but the quality of evidence of included studies were relatively low.Further refinement of the s should be needed as deeper clinical studies as available in future.
