<b><i>Objective:</i></b> Hyponatremia is a common electrolyte disorder in patients with stroke, which leads to various fatal complications. We performed a systematic review and meta-analysis to investigate the outcomes of acute stroke patients with hyponatremia. <b><i>Methods:</i></b> We searched MEDLINE, EMBASE, and the Cochrane Library databases for relevant literature in English published up to March 2020. Two review authors independently screened and selected the studies by assessing the eligibility and validity based on the inclusion criteria. Mortality at 90 days was set as the primary end point, and in-hospital mortality and length of hospital stay were set as the secondary end points. We conducted the data synthesis and analyzed the outcomes by calculating the odds ratio (OR) and mean difference. <b><i>Results:</i></b> Of 835 studies, 15 studies met the inclusion criteria (<i>n</i> = 10,745). The prevalence rate of stroke patients with hyponatremia was 7.0–59.2%. They had significantly higher 90-day mortality (OR, 1.73; 95% confidence interval (CI), 1.24–2.42) and longer length of hospital stay (mean difference, 10.68 days; 95% CI, 7.14–14.22) than patients without hyponatremia. Patients with hyponatremia had a higher tendency of in-hospital mortality than those without hyponatremia (OR, 1.61; 95% CI, 0.97–2.69). <b><i>Conclusions:</i></b> The development of hyponatremia in the clinical course of stroke is associated with higher short-term mortality and a longer hospital stay. Although the causal relationship is unclear, hyponatremia could be a significant predictor of poor outcomes after stroke.

Abstract Introduction Ventilator-associated pneumonia (VAP) is reported as the second most common nosocomial infection among critically ill patients with the incidence ranging from 2 to 16 episodes per 1000 ventilator days. The use of probiotics has been shown to have a promising effect in many RCTs. Our systematic review and meta-analysis were thus planned to determine the effect of probiotic use in critically ill ventilated adult patients on the incidence of VAP, length of hospital stay, length of ICU stay, duration of mechanical ventilation, the incidence of diarrhea, and the incidence of oropharyngeal colonization and in-hospital mortality. Methodology Systematic search of various databases (such as Embase, Cochrane, and Pubmed), published journals, clinical trials, and abstracts of the various major conferences were made to obtain the RCTs which compare probiotics with placebo for VAP prevention. The results were expressed as risk ratios or mean differences. Data synthesis was done using statistical software - Review Manager (RevMan) Version 5.4 (The Cochrane Collaboration, 2020). Results Nine studies met our inclusion criterion and were included in the meta-analysis. The incidence of VAP (risk ratio: 0.70, CI 0.56, 0.88; P = 0.002; I2 = 37%), duration of mechanical ventilation (mean difference −3.75, CI −6.93, −0.58; P 0.02; I2 = 96%), length of ICU stay (mean difference −4.20, CI −6.73, −1.66; P = 0.001; I2 = 84%) and in-hospital mortality (OR 0.73, CI 0.54, 0.98; P = 0.04; I2 = 0%) in the probiotic group was significantly lower than that in the control group. Probiotic administration was not associated with a statistically significant reduction in length of hospital stay (MD −1.94, CI −7.17, 3.28; P = 0.47; I2 = 88%), incidence of oro-pharyngeal colonization (OR 0.59, CI 0.33, 1.04; P = 0.07; I2 = 69%), and incidence of diarrhea (OR 0.59, CI 0.34, 1.03; P = 0.06; I2 = 38%). Discussion Our meta-analysis shows that probiotic administration has a promising role in lowering the incidence of VAP, the duration of mechanical ventilation, length of ICU stay, and in-hospital mortality.

Respiratory Muscle Weakness

Background: Increased frequency of chest infections in acute stroke patients may be the result of respiratory muscle weakness contributing to a weak cough and poor airway clearance. We undertook a systematic review of studies comparing respiratory muscle strength in acute stroke patients with age-matched controls. Method: A systematic review of literature was performed using the electronic databases Medline, EMBASE, ISI web of knowledge and the Scopus. The key words searched were stroke or cerebrovascular accident in combination with cough, inspiratory, expiratory or respiratory and strength or weakness. Studies were included if they compared stroke patients with age matched controls and measured maximum inspiratory or expiratory mouth pressure (PImax and PEmax) for inspiratory and expiratory muscle strength respectively. Results: The initial search identified 136 articles, 14 of which remained after screening for pre-defined inclusion criteria and removal of duplicates. Eleven were excluded after reviewing abstracts (5 did not assess muscle strength, 5 did not include healthy control group, 1 absolute values could not be obtained). A further study was identified from the reference lists of screened articles. The 4 studies that met inclusion criteria included 121 subjects. Mean PImax ranged from 75-99 cmH 2 O in controls and 37-74 cmH 2 O in stroke patients. (mean difference 41 cmH 2 O, 95% CI 54 to 29 cm H 2 O; P<0.0001). Mean PEmax ranged from 52-89 cm H 2 O in stroke patients and was also reduced compared with age matched controls (mean difference 55 cmH 2 O, 95% CI 61 to 48 cmH 2 O; P<0.0001). ( Fig 1 ). Conclusion: Individual studies and pooled data suggest that respiratory muscle strength is impaired in acute stroke patients. However, these studies are limited by small samples and design heterogeneity. Larger studies are needed to assess the relationship of respiratory muscle weakness with chest infections and clinical outcomes in the acute phase.

Abstract BACKGROUND Down syndrome (DS) is associated with a number of immunologic abnormalities and congenital heart disease (CHD) which increase susceptibility to respiratory syncytial virus (RSV). However current position statements from the American Academy of Pediatrics and the Canadian Paediatric Society do not recommend routine RSV prophylaxis with Palivizumab to all infants with DS, OBJECTIVES To conduct a systematic reviewand meta-analysis of observational studies to compare RSV-related hospitalization (RSVH) rates, length of hospital stay(LOS), need for intensive care and assisted ventilation in DS children <2 years of age compared with children without DS. DESIGN/METHODS Data Sources: The authors searched MEDLINE, Embase, CINAHL, reference lists of relevant articles, abstracts and conference proceedings, results of unpublished trials, and contacted the primary authors of relevant studies. Studies were included if data was provided on RSV-related hospitalization in children <2yr of age with and without DS. Data extraction & Synthesis: Two reviewers independently screened the search results, applied inclusion criteria and assessed methodological quality using the Newcastle-Ottawa Scale. Data was extracted and checked in duplicate. Main outcomes & measures: The primary outcome was RSV-related hospitalization. Secondary outcomes included length of hospital stay, need for intensive care and assisted ventilation. Sensitivity analysis was conducted for the primary outcome comparing DS infants without congenital heart disease (CHD) with non-DS infants. RESULTS 19 cohort studies met the inclusion criteria. Ten studies involving 1,390,380 children were analyzed. DS-children had significantly higher RSVH compared to non-DS children (Relative Risk, 6.97; 95% CI, 6.01 to 8.08; I2=0%; Figure 1a). Among children hospitalized with RSV, need for assisted ventilation (RR, 5.82; 95% CI, 1.81 to 18.69; I2=84%; Figure 1b) and LOS (Mean difference, 2.28 days; 95% CI, 1.61 to 2.96 days; I2=0%; Figure 1c) were significantly higher in DS-children. The sensitivity analysis also confirmed that DS children without CHD had a significantly higher RSVH rate compared to non-DS children (RR, 6.31; 95% CI, 4.83 to 8.23;I2=0%; Figure 1d). CONCLUSION Compared to children without DS, RSV-related hospitalization, need for assisted ventilation and length of RSV-related hospital stay is significantly higher in children with DS in the first 2 years of life. The results of this systematic review should prompt a favorable recommendation for routine RSV prophylaxis in both healthy and medically compromised DS children aged <2years.

(1) Background: Dysphagia is common in acute stroke patients and is a major risk factor for aspiration pneumonia. We investigated whether the early detection of dysphagia in stroke patients through screening could prevent the development of pneumonia and reduce mortality; (2) Methods: We searched the PubMed, Embase, Cochrane Library, and Scopus databases for relevant studies published up to November 2021. We included studies that performed dysphagia screening in acute stroke patients and evaluated whether it could prevent pneumonia and reduce mortality rates. The methodological quality of individual studies was evaluated using the Risk Of Bias In Non-randomized Studies of Interventions tool, and publication bias was evaluated by the funnel plot and Egger’s test; (3) Results: Of the 6593 identified studies, six studies met the inclusion criteria for analysis. The screening group had a significantly lower incidence of pneumonia than the nonscreening group did (odds ratio (OR), 0.60; 95% confidence interval (CI), 0.42 to 0.84; p = 0.003; I2, 66%). There was no significant difference in mortality rate between the two groups (OR, 0.61; 95% CI, 0.33 to 1.13; p = 0.11; I2, 93%); (4) Conclusions: Early screening for dysphagia in acute stroke patients can prevent the development of pneumonia.

Abstract Background: This systematic review and meta-analysis aimed to evaluate the effect of dexmedetomidine on lung function and prognosis.Methods: We searched PubMed, Embase and the Cochrane Library from inception to January 30, 2020 following the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) statement guidelines. Randomized controlled trials of dexmedetomidine associated with lung function were assessed. The primary outcomes are pH, PaO2, PaCO2, respiratory index (RI) and time to extubation. The secondary outcomes are PaO2/FiO2, length of hospital stay and events of pulmonary complications.Results: 17 trials of 924 patients were included. Compared with placebo group, dexmedetomidine group had higher PaO2 (MD: 10.96; 95% CI: from 0.77 to 21.15; p=0.04) and PaO2/FiO2 (MD: 30.77; 95% CI: from 19.11 to 42.43; p<0.00001). The dexmedetomidine group had lower PaCO2 (MD: -0.88; 95% CI: from -1.66 to -0.11; p=0.002) and shorter length of hospital stay (MD: -1.19; 95% CI: from -2.21 to -0.16; p=0.02). The dexmedetomidine group had lower occurrence of pulmonary complications (RR: 0.28; 95% CI: from 0.09 to 0.82; p=0.02). However, there is no significant difference in pH, respiratory index and extubation time.Conclusion: Dexmedetomidine has better influence on lung function and prognosis.

Objective To determine the impact of treatment for patients with nasal obstruction secondary to allergic rhinitis (AR) and nasal septal deviation (NSD) on sleep quality. Data Sources Primary studies were identified though PubMed, Scopus, Cochrane Library, and Web of Science. Review Methods A systematic review was performed by querying databases for articles published through August 2020. Studies were included that reported on objective sleep parameters (apnea-hypopnea index) and sinonasal and sleep-specific patient-reported outcome measures: Rhinoconjunctivitis Quality of Life Questionnaire, Nasal Obstruction Symptom Evaluation, Epworth Sleepiness Scale (EpSS), and Pittsburgh Sleep Quality Index (PSQI). Results The database search yielded 1414 unique articles, of which 28 AR and 7 NSD studies were utilized for meta-analysis. A total of 9037 patients (8515 with AR, 522 with NSD) were identified with a mean age of 35.0 years (35.3 for AR, 34.0 for NSD). Treatment for AR and NSD significantly improved subjective sleep quality. For AR, the EpSS mean difference was −1.5 (95% CI, –2.4 to –0.5; P = .002) and for the PSQI, –1.7 (95% CI, –2.1 to –1.2; P < .00001). For NSD, the EpSS mean difference was −3.2 (95% CI, –4.2 to –2.2; P < .00001) and for the PSQI, –3.4 (95% CI, –6.1 to –0.6; P = .02). Conclusion Subjective sleep quality significantly improved following treatment for AR and NSD. There were insufficient data to demonstrate that objective metrics of sleep quality similarly improved.

Abstract Objective We conducted a systematic review and meta-analysis to determine the effectiveness of comprehensive community-based interventions with ≥ 2 components in improving asthma outcomes in children. Methods A systematic search of Medline, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Excerpta Medica Database (EMBASE), Cochrane Library and hand search of reference collections were conducted to identify any research articles published in English between 2000 and 2019. All studies reporting community-based asthma interventions with ≥ 2 components (e.g., asthma self-management education, home environmental assessment or care coordination etc.) for children aged ≤ 18 years were included. Meta-analyses were performed using random-effects model to estimate pooled odds ratio (OR) with 95% confidence intervals (CIs). Results Of the 2352 studies identified, 21 studies were included in the final analysis: 19 pre-post interventions, one randomised controlled trial (RCT) and one retrospective study. Comprehensive asthma programs with multicomponent interventions were associated with significant reduction in asthma-related Emergency Department (ED) visits (OR = 0.26; 95% CI 0.20–0.35), hospitalizations (OR = 0.24; 95% CI 0.15–0.38), number of days (mean difference = − 2.58; 95% CI − 3.00 to − 2.17) and nights with asthma symptoms (mean difference = − 2.14; 95% CI − 2.94 to − 1.34), use of short-acting asthma medications/bronchodilators (BD) (OR = 0.28; 95% CI 0.16–0.51), and increase use of asthma action plan (AAP) (OR = 8.87; 95% CI 3.85–20.45). Conclusion Community-based asthma care using more comprehensive approaches may improve childhood asthma management and reduce asthma related health care utilization.

IntroductionHigh blood pressure (BP) in acute stroke has adverse outcomes. Transdermal glyceryl trinitrate (GTN) has beneficial properties in controlling BP. The 2016 meta-analysis and 2017 Cochrane review showed that transdermal GTN was beneficial in a small patient subgroup with stroke onset ≤6 hours. Larger studies focusing on this patient subgroup have since been conducted. We report the protocol for an updated systematic review and meta-analysis on the safety and benefits of transdermal GTN in acute stroke.Methods and analysisWe will search Medline, Pubmed, Embase, CINAHL and Cochrane Library from inception until June 2020 for randomised trials that report the efficacy and safety of transdermal GTN versus placebo/control therapy among adult patients with acute stroke. Primary outcomes include in-hospital mortality, BP lowering and late functional status. Secondary outcomes include early, late, resource utilisation and surrogate outcomes. Safety outcomes include reported adverse events. Reviewers will first screen titles and abstracts, and then full texts, to identify eligible studies. Independently and in duplicate, they will extract data, assess risk of bias (RoB) using a modified Cochrane RoB tool and quality of evidence using Grading of Recommendations, Assessment, Development and Evaluation. Disagreement will be resolved by discussion and consultation with an external reviewer if necessary. Using a random-effects model, we will report effect sizes using relative risks and 95% CIs. We will perform predefined subgroup analyses: intracerebral haemorrhage versus ischaemic stroke; minor (NIHSS (National Institutes of Health Stroke Scale) ≤five) versus major (NIHSS >five) ischaemic stroke; ischaemic stroke with versus without thrombolysis; prehospital versus non-prehospital settings; time from stroke to randomisation ≤6 versus >6 hours and high versus low overall RoB studies. We will also perform trial sequential analysis for the primary outcomes.Ethics and disseminationEthics board approval is unnecessary. PROSPERO registration has been obtained. The results will be disseminated through publication in a peer-reviewed journal.PROSPERO registration numberCRD42020173093.

Abstract   Esophagectomy has high morbidity and mortality, mainly due to pulmonary complications. Consequently, ventilatory support is a cornerstone in postoperative management. However, there is still no consensus on the timing for extubation. There is a fear that untimely extubation would lead to a high risk for an urgent reintubation. On the other hand, there is a risk for pulmonary damage in prolonged intubation. Thus, the present study aimed to compare early and late extubation after esophagectomy. Methods A systematic review was carried out on PubMed, Lilacs, Cochrane Library Central, and Embase, comparing early and late extubation after esophagectomy. The primary outcome was reintubation. Secondary outcomes included mortality; complications; pulmonary complications; pneumonia; anastomotic fistula; length of hospital stay; and ICU length of stay. The inclusion criteria were: a) clinical trials and cohort studies; b) adult patients (&gt; 18 years); and c) patients with esophageal cancer undergoing esophagectomy. The results were summarized by risk difference and mean difference. 95% confidence interval and random model were applied. Results Four articles were selected, comprising 490 patients. Early extubation did not increase the risk for reintubation, with a risk difference of 0.01 (95%CI -0.03; 0.04). Also, there was no difference for mortality −0.01 (95%CI -0.04; 0.03); complications −0.09 (95%CI -0.22; 0.05); pulmonary complications −0.05 (95%CI -0.13; 0.03); pneumonia −0.06 (95% CI-0.18; 0.05); anastomotic fistula −0.01 (95% CI -0.09; 0.08). In addition, there was no significant mean difference for: length of hospital stay −0.10 (95%CI -0.38; 0.1); and ICU length of stay 0.00 (95%CI -0.22; 0.22). Conclusion Early extubation after esophagectomy does not increase the risk for reintubation, mortality, complications, and lenght of stay.
