Review
AIM AND OBJECTIVE
This study aimed to determine whether the use of complete dentures has an influence on the respiratory capacity, assessed by the spirometry examination.
MATERIALS AND METHODS
A systematic review was conducted following the Preferred Reporting Items for Systematic Review and Meta-Analysis and registered in the International Prospective Register of Systematic Reviews (CRD42021255224). The PICO question (population/exposure/comparison/outcome) was "Does the use of complete dentures influence the respiratory capacity of a toothless subject?" A search strategy was adapted for the PubMed/MEDLINE, The Cochrane Library, OpenGrey, Lilacs, Scopus, and Embase databases. Inclusion criteria were prospective and retrospective studies. The new castle ottawa (NOS) scale and the Methodological Index for Non-randomized studies were selected to assess the quality of the included studies.
RESULTS
Four studies were selected, totalizing the evaluation of 242 participants, aged ranging from 40 to 73 years old. Two studies concluded that the use of complete dentures can negatively affect the respiratory capacity. One study stated that it did not interfere regardless of its use during spirometric measurements, and the other reported that dental prosthesis was required in cases of evaluation of the extrathoracic airways.
CONCLUSION
The use of complete dentures did not represent relevant changes from the reference values for pulmonary function in the spirometry test. Considering the results of this review, it is not yet possible to establish a clinical protocol for the use of complete dentures during the test.
CLINICAL SIGNIFICANCE
Oral rehabilitation with conventional complete dentures is widely used for the treatment of edentulism, especially in elderly patients. In addition, with aging, many complex changes in immunity and respiratory function contribute to the increase in the development of lung diseases. Therefore, it is important to establish a guidance regarding the use or not of the removable dental prostheses in the respiratory capacity test through spirometry examination.

Meta-Analysis
INTRODUCTION
Wheezing is a major problem in children, and respiratory viruses are often believed to be the causative agent. While molecular detection tools enable identification of respiratory viruses in wheezing children, it remains unclear if and how these viruses are associated with wheezing. The objective of this systematic review is to clarify the prevalence of different respiratory viruses in children with wheezing.
METHODS
We performed an electronic in Pubmed and Global Index Medicus on 01 July 2019 and manual search. We performed search of studies that have detected common respiratory viruses in children ≤18 years with wheezing. We included only studies using polymerase chain reaction (PCR) assays. Study data were extracted and the quality of articles assessed. We conducted sensitivity, subgroup, publication bias, and heterogeneity analyses using a random effects model.
RESULTS
The systematic review included 33 studies. Rhinovirus, with a prevalence of 35.6% (95% CI 24.6-47.3, I2 98.4%), and respiratory syncytial virus, at 31.0% (95% CI 19.9-43.3, I2 96.4%), were the most common viruses detected. The prevalence of other respiratory viruses was as follows: human bocavirus 8.1% (95% CI 5.3-11.3, I2 84.6%), human adenovirus 7.7% (95% CI 2.6-15.0, I2 91.0%), influenza virus6.5% (95% CI 2.2-12.6, I2 92.4%), human metapneumovirus5.8% (95% CI 3.4-8.8, I2 89.0%), enterovirus 4.3% (95% CI 0.1-12.9, I2 96.2%), human parainfluenza virus 3.8% (95% CI 1.5-6.9, I2 79.1%), and human coronavirus 2.2% (95% CI 0.6-4.4, I2 79.4%).
CONCLUSIONS
Our results suggest that rhinovirus and respiratory syncytial virus may contribute to the etiology of wheezing in children. While the clinical implications of molecular detection of respiratory viruses remains an interesting question, this study helps to illuminate the potential of role respiratory viruses in pediatric wheezing.

Review
INTRODUCTION
Severe asthma is characterized by frequent exacerbations, symptoms limiting daily activities and nocturnal symptoms. It requires the continuous use of medications, at high doses, and, sometimes, continuous use of oral corticosteroids, representing a significant burden to health system and society. This systematic review sought to address economic data related to severe asthma in Brazil.
METHOD
In June 2014, electronic searches were conducted to identify relevant publications. Quality criteria were developed and applied to each selected study. In order to compare results across the selected studies, costs were refined to an annual basis, grouped according to the study perspective, inflated and converted to 2014 USD.
RESULTS
Cost analyses from the Brazilian public health system perspective were derived from two studies and showed an average annual hospital cost per patient of 135 USD and 733 USD, respectively. From the family perspective, average annual direct costs per patient varied from 764 USD to 929 USD.
CONCLUSION
Hospitalizations and medications seem to be the most important resources funded by the Brazilian public health system and by patients and their families. Although further studies are necessary, as information on cost of this disease is scarce in Brazil, these findings suggest that there is a potential room for improving severe asthma care among Brazilian patients.

Meta-Analysis Review
BACKGROUND
The efficacy of macrolides in the management of asthma has been studied but remains controversial. We conducted a systematic review and meta-analysis of macrolides in the management of adult patients with asthma.
METHODS
Randomized controlled trials of macrolides used in adult patients with asthma were searched for in MEDLINE, EMBASE, PsycINFO, Cochrane Library, CINAHL, and Igaku Chuo Zasshi databases to evaluate the efficacy and safety of macrolides.
RESULTS
Seventeen reports with macrolide treatment durations ranging from 6 to 48 weeks were included. Macrolides did not reduce exacerbations requiring hospitalization, severe exacerbations, or rescue use of short-acting beta-2 agonist inhalers; improve lung function; decrease peripheral blood or sputum neutrophil counts; or decrease fractional exhaled nitric oxide compared to placebo. Macrolides statistically improved asthma control and quality of life but by less than the minimal clinically important difference. Peripheral blood eosinophil counts as well as serum and sputum eosinophilic cationic protein concentrations were significantly decreased with macrolides compared to placebo. The improvement of asthma symptoms and airway hyperresponsiveness varied by study. The safety profile of macrolides was comparable to that of placebo.
CONCLUSIONS
Although macrolides have some useful clinical aspects, there is not sufficient evidence to recommend their use in the management of adult patients with asthma.

The Cochrane Database of Systematic... Jun 2011Bronchodilators are commonly used for acute bronchiolitis, despite uncertain effectiveness. (Meta-Analysis)
Meta-Analysis Review
BACKGROUND
Bronchodilators are commonly used for acute bronchiolitis, despite uncertain effectiveness.
OBJECTIVES
To examine the efficacy and safety of epinephrine in children less than two with acute viral bronchiolitis.
SEARCH STRATEGY
We searched CENTRAL (2010, Issue 3) which contains the Acute Respiratory Infections Group's Specialized Register, MEDLINE (1950 to September Week 2, 2010), EMBASE (1980 to September 2010), Scopus (1823 to September 2010), PubMed (March 2010), LILACS (1985 to September 2010) and Iran MedEx (1998 to September 2010).
SELECTION CRITERIA
We included randomized controlled trials comparing epinephrine to placebo or another intervention involving children less than two years with acute viral bronchiolitis. Studies were included if the trials presented data for at least one quantitative outcome of interest.We selected primary outcomes a priori, based on clinical relevance: rate of admission by days one and seven of presentation for outpatients, and length of stay (LOS) for inpatients. Secondary outcomes included clinical severity scores, pulmonary function, symptoms, quality of life and adverse events.
DATA COLLECTION AND ANALYSIS
Two review authors independently screened the searches, applied inclusion criteria, assessed risk of bias and graded the evidence. We conducted separate analyses for different comparison groups (placebo, non-epinephrine bronchodilators, glucocorticoids) and for clinical setting (inpatient, outpatient).
MAIN RESULTS
We included 19 studies (2256 participants). Epinephrine versus placebo among outpatients showed a significant reduction in admissions at Day 1 (risk ratio (RR) 0.67; 95% confidence interval (CI) 0.50 to 0.89) but not at Day 7 post-emergency department visit. There was no difference in LOS for inpatients. Epinephrine versus salbutamol showed no differences among outpatients for admissions at Day 1 or 7. Inpatients receiving epinephrine had a significantly shorter LOS compared to salbutamol (mean difference -0.28; 95% CI -0.46 to -0.09). One large RCT showed a significantly shorter admission rate at Day 7 for epinephrine and steroid combined versus placebo (RR 0.65; 95% CI 0.44 to 0.95). There were no important differences in adverse events.
AUTHORS' CONCLUSIONS
This review demonstrates the superiority of epinephrine compared to placebo for short-term outcomes for outpatients, particularly in the first 24 hours of care. Exploratory evidence from a single study suggests benefits of epinephrine and steroid combined for later time points. More research is required to confirm the benefits of combined epinephrine and steroids among outpatients. There is no evidence of effectiveness for repeated dose or prolonged use of epinephrine or epinephrine and dexamethasone combined among inpatients.

Review
INTRODUCTION
Changes in air pressure during flying can cause ear-drum pain and perforation, vertigo, and hearing loss. It has been estimated that 10% of adults and 22% of children might have changes to the ear drum after a flight, although perforation is rare. Symptoms usually resolve spontaneously.
METHODS AND OUTCOMES
We conducted a systematic review and aimed to answer the following clinical question: What are the effects of interventions to prevent middle-ear pain during air travel? We searched: Medline, Embase, The Cochrane Library and other important databases up to July 2014 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).
RESULTS
We found three studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.
CONCLUSIONS
In this systematic review we present information relating to the effectiveness and safety of the following interventions: nasal balloon inflation, nasal decongestants (topical), and oral pseudoephedrine.

Meta-Analysis Review
BACKGROUND
Acetylcysteine and carbocysteine are the most commonly prescribed mucolytic drugs in Brazil and many European and African countries. To our knowledge, no systematic review has been published on their efficacy and safety for acute upper and lower respiratory tract infections (RTIs) in children without chronic broncho-pulmonary disease.
OBJECTIVES
The objective was to assess the efficacy and safety and to establish a benefit-risk ratio of acetylcysteine and carbocysteine as symptomatic treatments for acute upper and lower RTIs in paediatric patients without chronic broncho-pulmonary disease.
SEARCH METHODS
We searched CENTRAL (2013, Issue 2), MEDLINE (1966 to February week 3, 2013), EMBASE (1980 to March 2013), Micromedex (2010), Pascal (1987 to 2004) and Science Citation Index (1974 to March 2013).
SELECTION CRITERIA
To study efficacy, we used randomised controlled trials (RCTs) comparing the use of acetylcysteine or carbocysteine versus placebo, either alone or as an add-on therapy. To study safety, we used trials comparing acetylcysteine or carbocysteine versus active treatment or no treatment and case reports.
DATA COLLECTION AND ANALYSIS
In this review update two review authors (YD, MC), with help from a colleague, extracted data and assessed trial quality. We performed a subgroup analysis of children younger than two years of age.
MAIN RESULTS
We included six trials involving 497 participants to study efficacy. They showed some benefit (e.g. reduction of cough at day seven) from mucolytic agents, although differences were of little clinical relevance. No conclusion was drawn about the subgroup of infants younger than two years because data were unavailable. Thirty-four studies, including the previous six trials involving 2064 children, were eligible to study safety. Overall safety was good but very few data were available to evaluate safety in infants younger than two years. However, 59 cases of paradoxically increased bronchorrhoea observed in infants were reported to the French pharmacovigilance system.
AUTHORS' CONCLUSIONS
The results have to be interpreted with caution because they are based on a limited number of participants included in studies whose methodological quality is questionable. Acetylcysteine and carbocysteine seem to have a limited efficacy and appear to be safe in children older than two years. These results should take into consideration the fact that acetylcysteine and carbocysteine are prescribed for self limiting diseases (for example, acute cough, bronchitis). Given strong concerns about safety, these drugs should only be used for acute upper and lower RTIs in the context of a RCT with regards to children younger than two years.

Efficacy and safety of treatment with biologicals (benralizumab, dupilumab and omalizumab) for severe allergic asthma: A systematic review for the EAACI Guidelines - recommendations on the use of biologicals in severe asthma.
Allergic asthma is a frequent asthma phenotype. Both IgE and type 2 cytokines are increased, with some degree of overlap with other phenotypes. Systematic reviews assessed the efficacy and safety of benralizumab, dupilumab and omalizumab (alphabetical order) vs standard of care for patients with uncontrolled severe allergic asthma. PubMed, Embase and Cochrane Library were searched to identify RCTs and health economic evaluations, published in English. Critical and important asthma-related outcomes were evaluated. The risk of bias and the certainty of the evidence were assessed using GRADE. All three biologicals reduced with high certainty the annualized asthma exacerbation rate: benralizumab incidence rate ratios (IRR) 0.63 (95% CI 0.50 - 0.81); dupilumab IRR 0.58 (95%CI 0.47 - 0.73); and omalizumab IRR 0.56 (95%CI 0.42 - 0.73). Benralizumab and dupilumab improved asthma control with high certainty and omalizumab with moderate certainty; however, none reached the minimal important difference (MID). Both benralizumab and omalizumab improved QoL with high certainty, but only omalizumab reached the MID. Omalizumab enabled ICS dose reduction with high certainty. Benralizumab and omalizumab showed an increase in drug-related adverse events (AEs) with low to moderate certainty. All three biologicals had moderate certainty for an ICER/QALY value above the willingness to pay threshold. There was high certainty that in children 6-12 years old omalizumab decreased the annualized exacerbation rate [IRR 0.57 (95%CI 0.45-0.72)], improved QoL [relative risk 1.43 (95%CI 1.12 -1.83)], reduced ICS [mean difference (MD) -0.45 (95% CI -0.58 to -0.32)] and rescue medication use [ MD -0.41 (95%CI -0.66 to -0.15)].

Meta-Analysis Review
BACKGROUND
Understanding the comparative effectiveness of treatments for patients with unexplained or refractory cough is important to increase awareness of proven therapies and their potential adverse effects in this unique population.
METHODS
We performed a literature search for English-language studies published up to June 2012 that compared symptomatic therapies for chronic cough. Two investigators screened each abstract and full-text article for inclusion, abstracted data, and rated quality. Meta-analysis with random-effects models was used to summarize effects of treatments.
RESULTS
We identified 49 studies (3,067 patients) comprising 68 therapeutic comparisons. Of the studied agents, opioid and certain nonopioid and nonanesthetic antitussives had demonstrated efficacy for chronic cough in adults. Compared with placebo, effect sizes (standardized mean differences for cough severity and rate ratios for cough frequency) for opioids were 0.55 (95% CI, 0.38-0.72; P < .0001) and 0.57 (95% CI, 0.36-0.91; P = .0260), respectively. For dextromethorphan, effect sizes were 0.37 (95% CI, 0.19-0.56; P = .0008) and 0.40 (95% CI, 0.18-0.85; P = .0248), respectively. The overall strength of evidence was limited by inconsistency and imprecision of results and by small numbers of direct comparisons. Nonpharmacologic therapies and the management of cough in children were infrequently studied.
CONCLUSIONS
Although evidence is limited, opioid and certain nonopioid and nonanesthetic antitussives demonstrated efficacy for treating chronic cough in adults. There is a need for further studies in patients with unexplained or refractory cough as well as for more systematic study designs, assessment of patient-centered outcomes, and reporting.

Meta-Analysis Review
BACKGROUND
Montelukast is a highly selective and specific cysteinyl leukotriene receptor antagonist used in the treatment of asthma. Whether montelukast as adjuvant therapy can significantly and safely treat adults with cough variant asthma (CVA) remains inconclusive.
AIMS
This meta-analysis systematically evaluated the efficacy and safety of montelukast as an adjuvant treatment for adults with CVA.
MATERIALS AND METHODS
Randomized controlled trials (RCTs) on montelukast combined with inhaled corticosteroids (ICS) and long-acting β2 agonists (LABAs) to treat CVA in adults, from inception to March 6, 2023, were retrieved from the CNKI, Wanfang, VIP, CBM, PubMed, Embase, Cochrane Library, and Web of Science databases and Clinical Trials website. Review Manager (version 5.4) and Stata (version 15.0) were used to conduct the meta-analysis.
RESULTS
A total of 15 RCTs were ultimately included in the meta-analysis. It was established that montelukast as adjuvant therapy raised the total effective rate (RR = 1.20, 95% confidence interval [CI] [1.13, 1.27], P < 0.01) and improved the FEV1% (SMD = 0.91, 95% CI [0.40, 1.41], P < 0.01), PEF% (SMD = 0.63, 95% CI [0.38, 0.88], P < 0.01), FEV1 (SMD = 1.15, 95% CI [0.53, 1.77], P < 0.01), PEF (SMD = 0.64, 95% CI [0.42, 0.86], P < 0.01), and FEV1/FVC% (SMD = 0.76, 95% CI [0.51, 1.01], P < 0.01) and reduced the recurrence rate (RR = 0.28, 95% CI [0.15, 0.53], P < 0.01). The incidence of adverse reactions was higher in the montelukast auxiliary group compared to the control group but with no statistical difference (RR = 1.32, 95% CI [0.89, 1.96], P = 0.17).
CONCLUSION
Existing evidence indicated that the use of montelukast as an adjuvant therapy had therapeutic efficacy superior to ICS + LABA alone for the treatment of adult patients with CVA. However, further research is needed, especially a combination of high-quality long-term prospective studies and carefully designed RCTs.
