BACKGROUND
There is scarce evidence verifying the impact of neuraminidase inhibitors (NAIs) in reducing influenza complications. The aim was to evaluate the available evidence from randomized-controlled trials (RCT) regarding the efficacy and safety of NAIs in reducing influenza complications.
METHODS
A systematic search of the literature was performed in the Cochrane Library, PubMed and Web of Science databases (2006-2019). Eligibility criteria were RCT that enrolled patients of any age or clinical severity with seasonal influenza (HN, HN or B) or influenza-like syndrome and receiving NAIs comparing to placebo therapy.
RESULTS
Eighteen RCTs (9004 patients) were included: nine focused on oral oseltamivir, six on inhaled zanamivir, and three on intravenous peramivir. Administration of NAIs therapy significantly decreased the time to clinical resolution (median difference: -17.7 hours; and total influenza-related complications (OR: 0.64, 95%CI: 0.51-0.82). In addition, NAIs significantly decreased acute otitis media complication (OR: 0.50, 95%CI: 0.31-0.82) and need for antibiotic treatment (OR: 0.64, 95%CI: 0.46-0.90); and showed a trend towards a reduced occurrence of pneumonia (OR: 0.44, 95%CI: 0.10-2.00), bronchitis (OR: 0.80, 95%CI: 0.43-1.48), sinusitis (OR: 0.73, 95%CI: 0.40-1.32), asthma exacerbations (OR: 0.57, 95%CI: 0.28-1.16), and hospitalizations (OR: 0.57, 95%CI: 0.24-1.38). The overall proportion of AEs tend to increase with NAIs treatment (OR: 1.16, 95%CI: 0.92-1.47). Use of NAIs was associated with a significant increase of nausea and vomiting (OR: 1.61, 95%CI: 1.04-2.50) and a decrease on diarrhea (OR: 0.81, 95%CI: 0.65-1.00).
CONCLUSIONS
NAIs are effective in reducing time to clinical resolution, total influenza-related complications, otitis media, and need of antibiotic administration. Reductions on mortality, pneumonia, asthma exacerbations or hospitalization rates only did demonstrate a trend benefit in favor of NAIs. The only significant AE is the increased occurrence of nausea and vomiting.

Meta-Analysis
BACKGROUND
Acute bronchiolitis is a significant burden on children, their families and healthcare facilities. It mostly affects children younger than two years of age. Treatment involves adequate hydration, humidified oxygen supplementation, and nebulisation of medications, such as salbutamol, epinephrine, and hypertonic saline. The effectiveness of magnesium sulphate for acute bronchiolitis is unclear.
OBJECTIVES
To assess the effects of magnesium sulphate in acute bronchiolitis in children up to two years of age.
SEARCH METHODS
We searched CENTRAL, MEDLINE, Embase, LILACS, CINAHL, and two trials registries to 30 April 2020. We contacted trial authors to identify additional studies. We searched conference proceedings and reference lists of retrieved articles. Unpublished and published studies were eligible for inclusion.
SELECTION CRITERIA
Randomised controlled trials (RCTs) and quasi-RCTs, comparing magnesium sulphate, alone or with another treatment, with placebo or another treatment, in children up to two years old with acute bronchiolitis. Primary outcomes were time to recovery, mortality, and adverse events. Secondary outcomes were duration of hospital stay, clinical severity score at 0 to 24 hours and 25 to 48 hours after treatment, pulmonary function test, hospital readmission within 30 days, duration of mechanical ventilation, and duration of intensive care unit stay.
DATA COLLECTION AND ANALYSIS
We used standard methodological procedures expected by Cochrane. We used GRADE methods to assess the certainty of the evidence.
MAIN RESULTS
We included four RCTs (564 children). One study received funding from a hospital and one from a university; two studies did not report funding sources. Comparator interventions differed among all four trials. Studies were conducted in Qatar, Turkey, Iran, and India. We assessed two studies to be at an overall low risk of bias, and two to be at unclear risk of bias, overall. The certainty of the evidence for all outcomes and comparisons was very low except for one: hospital re-admission rate within 30 days of discharge for magnesium sulphate versus placebo. None of the studies measured time to recovery, duration of mechanical ventilation, duration of intensive care unit stay, or pulmonary function. There were no events of mortality or adverse effects for magnesium sulphate compared with placebo (1 RCT, 160 children). The effects of magnesium sulphate on clinical severity are uncertain (at 0 to 24 hours: mean difference (MD) on the Wang score 0.13, 95% confidence interval (CI) -0.28 to 0.54; and at 25 to 48 hours: MD on the Wang score -0.42, 95% CI -0.84 to -0.00). Magnesium sulphate may increase hospital re-admission rate within 30 days of discharge (risk ratio (RR) 3.16, 95% CI 1.20 to 8.27; 158 children; low-certainty evidence). None of our primary outcomes were measured for magnesium sulphate compared with hypertonic saline (1 RCT, 220 children). Effects were uncertain on the duration of hospital stay in days (MD 0.00, 95% CI -0.28 to 0.28), and on clinical severity on the Respiratory Distress Assessment Instrument (RDAI) score at 25 to 48 hours (MD 0.10, 95% CI -0.39 to 0.59). There were no events of mortality or adverse effects for magnesium sulphate, with or without salbutamol, compared with salbutamol (1 RCT, 57 children). Effects on the duration of hospital stay were uncertain (magnesium sulphate: 24 hours (95% CI 25.8 to 47.4), magnesium sulphate + salbutamol: 20 hours (95% CI 15.3 to 39.0), and salbutamol: 24 hours (95% CI 23.4 to 76.9)). None of our primary outcomes were measured for magnesium sulphate + epinephrine compared with no treatment or normal saline + epinephrine (1 RCT,120 children). Effects were uncertain for the duration of hospital stay in hours (MD -0.40, 95% CI -3.94 to 3.14), and for RDAI scores (0 to 24 hours: MD -0.20, 95% CI -1.06 to 0.66; and 25 to 48 hours: MD -0.90, 95% CI -1.75 to -0.05).
AUTHORS' CONCLUSIONS
There is insufficient evidence to establish the efficacy and safety of magnesium sulphate for treating children up to two years of age with acute bronchiolitis. No evidence was available for time to recovery, duration of mechanical ventilation and intensive care unit stay, or pulmonary function. There was no information about adverse events for some comparisons. Well-designed RCTs to assess the effects of magnesium sulphate for children with acute bronchiolitis are needed. Important outcomes, such as time to recovery and adverse events should be measured.

Meta-Analysis
INTRODUCTION
The advent of genome amplification assays has allowed description of new respiratory viruses and to reconsider the role played by certain respiratory viruses in bronchiolitis. This systematic review and meta-analysis was initiated to clarify the prevalence of respiratory viruses in children with bronchiolitis in the pre-COVID-19 pandemic era.
METHODS
We performed an electronic search through Pubmed and Global Index Medicus databases. We included observational studies reporting the detection rate of common respiratory viruses in children with bronchiolitis using molecular assays. Data was extracted and the quality of the included articles was assessed. We conducted sensitivity, subgroups, publication bias, and heterogeneity analyses using a random effect model.
RESULTS
The final meta-analysis included 51 studies. Human respiratory syncytial virus (HRSV) was largely the most commonly detected virus 59.2%; 95% CI [54.7; 63.6]). The second predominant virus was Rhinovirus (RV) 19.3%; 95% CI [16.7; 22.0]) followed by Human bocavirus (HBoV) 8.2%; 95% CI [5.7; 11.2]). Other reported viruses included Human Adenovirus (HAdV) 6.1%; 95% CI [4.4; 8.0]), Human Metapneumovirus (HMPV) 5.4%; 95% CI [4.4; 6.4]), Human Parainfluenzavirus (HPIV) 5.4%; 95% CI [3.8; 7.3]), Influenza 3.2%; 95% CI [2.2; 4.3], Human Coronavirus (HCoV) 2.9%; 95% CI [2.0; 4.0]), and Enterovirus (EV) 2.9%; 95% CI [1.6; 4.5]). HRSV was the predominant virus involved in multiple detection and most codetections were HRSV + RV 7.1%, 95% CI [4.6; 9.9]) and HRSV + HBoV 4.5%, 95% CI [2.4; 7.3]).
CONCLUSIONS
The present study has shown that HRSV is the main cause of bronchiolitis in children, we also have Rhinovirus, and Bocavirus which also play a significant role. Data on the role played by SARS-CoV-2 in children with acute bronchiolitis is needed.

Meta-Analysis
BACKGROUND
Inhaled hypertonic saline (HS) has shown benefit in decreasing airway edema in acute bronchiolitis which is the most common lower respiratory infection resulting in dyspnea among infants under 2 years old. The aim of this systematic review and meta-analysis was to evaluate the efficacy and safety of HS in the implementation of treatment with nebulized HS among children with bronchiolitis.
METHODS
A systematic literature search was conducted using Cochrane Library, PubMed, EMBASE and Airiti Library (Chinese Database) for randomized controlled trials from inception to July 2019. We calculated pooled risk ratios (RR), mean difference (MD) and 95% CI using RevMan 5.3 for meta-analysis.
RESULTS
There were 4186 children from 32 publications included. Compared to the control group, the HS group exhibited significant reduction of severity of respiratory distress, included studies used the Clinical Severity Score (n = 8; MD, - 0.71; 95% CI, - 1.15 to - 0.27; I = 73%) and full stop after Respiratory Distress Assessment Instrument (n = 5; MD, - 0.60; 95% CI, - 0.95 to - 0.26; I = 0%) for evaluation respectively. Further, the HS group decreased the length of hospital stay 0.54 days (n = 20; MD, - 0.54; 95% CI, - 0.86 to - 0.23; I = 81%).
CONCLUSIONS
We conclude that nebulization with 3% saline solution is effective in decreasing the length of hospital stay and the severity of symptoms as compared with 0.9% saline solution among children with acute bronchiolitis. Further rigorous randomized controlled trials with large sample size are needed.

Meta-Analysis
AIMS
In light of the recent safety concerns relating to NSAID use in COVID-19, we sought to evaluate cardiovascular and respiratory complications in patients taking NSAIDs during acute lower respiratory tract infections.
METHODS
We carried out a systematic review of randomised controlled trials and observational studies. Studies of adult patients with short-term NSAID use during acute lower respiratory tract infections, including bacterial and viral infections, were included. Primary outcome was all-cause mortality. Secondary outcomes were cardiovascular, renal and respiratory complications.
RESULTS
In total, eight studies including two randomised controlled trials, three retrospective and three prospective observational studies enrolling 44 140 patients were included. Five of the studies were in patients with pneumonia, two in patients with influenza, and one in a patient with acute bronchitis. Meta-analysis was not possible due to significant heterogeneity. There was a trend towards a reduction in mortality and an increase in pleuro-pulmonary complications. However, all studies exhibited high risks of bias, primarily due to lack of adjustment for confounding variables. Cardiovascular outcomes were not reported by any of the included studies.
CONCLUSION
In this systematic review of NSAID use during acute lower respiratory tract infections in adults, we found that the existing evidence for mortality, pleuro-pulmonary complications and rates of mechanical ventilation or organ failure is of extremely poor quality, very low certainty and should be interpreted with caution. Mechanistic and clinical studies addressing the captioned subject are urgently needed, especially in relation to COVID-19.

Children exposed to secondhand smoke (SHS) are at increased risk for disease. We sought to estimate the medical costs among Korean children who were exposed to SHS at home. A Markov model was developed, including five diseases (asthma, acute otitis media, acute bronchitis, pneumonia and sudden infant death syndrome) that were significantly associated with SHS in children based on a systematic review. The time horizon of the analysis was 20 years (from birth to adulthood), and the cycle length was 1 week. The direct healthcare costs were discounted annually at 5%. Univariate and probabilistic sensitivity analyses were conducted. The Markov model estimated the healthcare costs for 20 years as 659.61 USD per exposed child, an increase of approximately 30% compared to the cost per unexposed child (507.32 USD). Sensitivity analysis suggested that the younger the age of the exposure, the greater the incremental healthcare costs incurred, implying that infants and young children were especially vulnerable to the SHS exposure. Findings of this study could provide key baseline data for future economic evaluations on SHS control policies in South Korea.

The characteristics of the frequent exacerbator with chronic bronchitis phenotype and non-exacerbator phenotype in patients with chronic obstructive pulmonary disease: a meta-analysis and system review.
BACKGROUND
Chronic obstructive pulmonary disease (COPD) patients with different phenotypes show different clinical characteristics. Therefore, we conducted a meta-analysis to explore the clinical characteristics between the non-exacerbator (NE) phenotype and the frequent exacerbator with chronic bronchitis (FE-CB) phenotype among patients with COPD.
METHODS
CNKI, Wan fang, Chongqing VIP, China Biology Medicine disc, PubMed, Cochrane Library, and EMBASE databases were searched from the times of their inception to April 30, 2019. All studies that reported the clinical characteristics of the COPD phenotypes and which met the inclusion criteria were included. The quality assessment was analyzed by Cross-Sectional/Prevalence Study Quality recommendations. The meta-analysis was carried out using RevMan5.3.
RESULTS
Ten cross-sectional observation studies (n = 8848) were included. Compared with the NE phenotype, patients with the FE-CB phenotype showed significantly lower forced expiratory volume in 1 s percent predicted (FEV%pred) (mean difference (MD) -8.50, 95% CI -11.36--5.65, P < 0.001, I = 91%), forced vital capacity percent predicted (FVC%pred) [MD - 6.69, 95% confidence interval (CI) -7.73--5.65, P < 0.001, I = 5%], and forced expiratory volume in 1 s/forced vital capacity (FEV/FVC) (MD -3.76, 95% CI -4.58--2.95,P < 0.001, I = 0%); in contrast, Charlson comorbidity index (MD 0.47, 95% CI 0.37-0.58, P < 0.001, I = 0], COPD assessment test (CAT) score (MD 5.61, 95% CI 4.62-6.60, P < 0.001, I = 80%), the quantity of cigarettes smoked (pack-years) (MD 3.09, 95% CI 1.60-4.58, P < 0.001, I = 41%), exacerbations in previous year (2.65, 95% CI 2.32-2.97, P < 0.001, I = 91%), modified Medical British Research Council (mMRC) score (MD 0.72, 95% CI 0.63-0.82, P < 0.001, I = 57%), and body mass index (BMI), obstruction, dyspnea, exacerbations (BODEx) (MD 1.78, 95% CI 1.28-2.28, P < 0.001, I = 91%), I = 34%) were significantly higher in patients with FE-CB phenotype. No significant between-group difference was observed with respect to BMI (MD-0.14, 95% CI -0.70-0.42, P = 0.62, I = 75%).
CONCLUSION
COPD patients with the FE-CB phenotype had worse pulmonary function and higher CAT score, mMRC scores, frequency of acute exacerbations, and the quantity of cigarettes smoked (pack-years) than those with the NE phenotype.

Meta-Analysis
To systematically review the effectiveness and safety of Tanreqing Injection in treating acute exacerbation of chronic bronchitis( AECB). CNKI,Wan Fang,VIP,CBM,Medline,Cochrane Library,EMbase and Web of Science were retrieved,and randomized controlled trials for the effect of Tanreqing Injection in the treatment of acute exacerbation of chronic bronchitis were screened. The quality of the included studies was evaluated according to the Cochrane Handbook's evaluation criteria. The data was analyzed by RevMan 5.3. Totally 23 RCTs involving 1 901 patients were included,including 952 in the experimental group and 949 in the control group. The Meta-analysis demonstrated that in terms of the disappearance time of fever,the group of Tanreqing Injection combined with the conventional therapy was superior to conventional therapy group( RR =-1. 03,95%CI[-1. 45,-0. 62],P<0. 000 01); compared with the conventional therapy group,the group of Tanreqing Injection combined with conventional therapy had a higher cure rate for AECB( RR = 1. 17,95% CI[1. 13,1. 23],P < 0. 000 01). The group of Tanreqing Injection combined with levofloxacin had a higher cure rate for AECB than the levofloxacin group( RR = 1. 23,95% CI[1. 08,1. 41],P = 0. 002). The group of Tanreqing Injection combined with cefuroxime had a higher cure rate for AECB than the cefuroxime group( RR = 1. 22,95%CI[1. 05,1. 42],P = 0. 01).The group of Tanreqing Injection combined with cefoperazone sodium and sulbactam sodium had a higher cure rate for AECB than the group of cefoperazone sodium and sulbactam sodium( RR = 1. 22,95% CI[1. 04,1. 44],P = 0. 02). The outcomes of disappearance time of cough and expectoration had a huge heterogeneity,so were used for descriptive analysis. The adverse reactions mainly included skin rash,dizziness,gastrointestinal reactions. Based on the available data and the results of the analysis,the group of Tanreqing Injection combined with Western medicine has a higher cure rate for acute exacerbation of chronic bronchitis,and the effect in reducing symptoms disappearance time. In view of the limited number of included studies,small sample size and low methodological quality,the results of this study need to be confirmed with high-level clinical trials.

Meta-Analysis
To systematically review the effectiveness and safety of Reduning Injection in the treatment of acute tracheal-bronchitis.Four Chinese databases( CNKI,VIP,Wan Fang,Sino Med) and three English databases( Cochrane Library,Medline,Web of Science) were systematically and comprehensively retrieved. The retrieval time was from the establishment of each database to April 2019.Randomized controlled trials( RCTs) for the treatment of acute tracheal-bronchitis with Reduning Injection were collected. Two researchers independently conducted literature screening,data extraction and risk assessment for bias. Rev Man 5.3 software was used for data analysis. Fourteen studies were included,and the total sample size was 1 652 at last. Meta-analysis results show that in the aspect of total clinical effective rate,Reduning Injection was superior to ribavirin( RR = 1. 37,95%CI[1. 28,1. 47],P<0. 000 01); Reduning Injection combined with conventional therapy was better than conventional therapy alone( RR = 1. 14,95% CI[1. 09,1. 19],P <0. 000 01); Reduning Injection combined with azithromycin was better than azithromycin therapy alone( RR = 1. 21,95% CI[1. 07,1. 37],P = 0. 002). In the aspect of clinical symptoms,the time in average fever disappearance of Reduning Injection therapy was shorter than that of ribavirin therapy( MD =-1.68,95%CI[-1. 72,-1. 49],P<0. 000 01); the time in cough disappearance of Reduning Injection therapy was shorter than that of ribavirin therapy( MD =-2. 57,95%CI[-2. 91,-2. 24],P<0. 000 01); the time in lung rales disappearance,Reduning Injection therapy was superior to ribavirin therapy( MD =-2. 26,95% CI[-2. 71,-1. 80],P<0. 000 01),and Reduning Injection combined with conventional therapy was superior to conventional therapy( MD =-1. 77,95% CI[-1. 95,-1. 59],P<0. 000 01). Based on the findings,Reduning Injection can improve the total effective rate,reduce the average time of disappearance in fever,cough and lung rales,with mild adverse reactions and a low incidence. However,the quality of the literatures included is not high,it is necessary to adopt large-sample-size,rigorously designed clinical trial protocols in line with the international standards,in a bid to improve the quality of evidence.

Complementary Therapies in Medicine Mar 2020Our review summarizes published literature of complementary and alternative medicine (CAM) used for the treatment of acute bronchitis in children.
OBJECTIVE
Our review summarizes published literature of complementary and alternative medicine (CAM) used for the treatment of acute bronchitis in children.
BACKGROUND
Acute bronchitis is one of the most frequent pediatric diseases and has high prevalence for in- and outpatient care. Acute bronchitis is mainly a viral-caused infection, but a high and inappropriate use of antibiotics has been demonstrated in many countries. As CAM therapies might reduce the use of antibiotics and can complement conventional therapies in children, they could be an appropriate treatment option.
METHODS
A systematic literature search was conducted using general and complementary and alternative medicine (CAM)-specific databases. A search term including 65 CAM-associated definitions was applied.
RESULTS
Literature search revealed 309 articles, whereby 18 articles hit search criteria. These clinical trials were subgrouped into the categories herbal medicine, anthroposophic medicine and homeopathy. The most often studied approaches are herbal remedies, in particular the Pelargonium sidoides extract, EPs® 7630. Its efficacy was demonstrated in three placebo-controlled trials and two observational studies. Anthroposophic approaches (mainly ribwort-containing remedies) were investigated in two controlled trials and three observational studies. Two studies were found investigating the homeopathic remedies Monapax® and Droperteel®.
CONCLUSION
Study results indicate a favorable effect of investigated CAM approaches. However, only three of 18 studies were randomized controlled trials (RCTs), so a reliable statement on effectiveness was not possible and further RCTs are indispensable.
