Meta-Analysis
BACKGROUND
There is widespread, increasing use of magnesium sulphate in obstetric practice for pre-eclampsia, eclampsia, and preterm fetal neuroprotection; benefit for preventing preterm labour and birth (tocolysis) is unproven. We conducted a systematic review and meta-analysis to assess whether antenatal magnesium sulphate is associated with unintended adverse neonatal outcomes.
METHODS AND FINDINGS
CINAHL, Cochrane Library, LILACS, MEDLINE, Embase, TOXLINE, and Web of Science, were searched (inceptions to 3 September 2019). Randomised, quasi-randomised, and non-randomised trials, cohort and case-control studies, and case reports assessing antenatal magnesium sulphate for pre-eclampsia, eclampsia, fetal neuroprotection, or tocolysis, compared with placebo/no treatment or a different magnesium sulphate regimen, were included. The primary outcome was perinatal death. Secondary outcomes included pre-specified and non-pre-specified adverse neonatal outcomes. Two reviewers screened 5,890 articles, extracted data, and assessed risk of bias following Cochrane Handbook and RTI Item Bank guidance. For randomised trials, pooled risk ratios (RRs) or mean differences, with 95% confidence intervals (CIs), were calculated using fixed- or random-effects meta-analysis. Non-randomised data were tabulated and narratively summarised. We included 197 studies (40 randomised trials, 138 non-randomised studies, and 19 case reports), of mixed quality. The 40 trials (randomising 19,265 women and their babies) were conducted from 1987 to 2018 across high- (16 trials) and low/middle-income countries (23 trials) (1 mixed). Indications included pre-eclampsia/eclampsia (24 trials), fetal neuroprotection (7 trials), and tocolysis (9 trials); 18 trials compared magnesium sulphate with placebo/no treatment, and 22 compared different regimens. For perinatal death, no clear difference in randomised trials was observed between magnesium sulphate and placebo/no treatment (RR 1.01; 95% CI 0.92 to 1.10; 8 trials, 13,654 babies), nor between regimens. Eleven of 138 non-randomised studies reported on perinatal death. Only 1 cohort (127 babies; moderate to high risk of bias) observed an increased risk of perinatal death with >48 versus ≤48 grams magnesium sulphate exposure for tocolysis. No clear secondary adverse neonatal outcomes were observed in randomised trials, and a very limited number of possible adverse outcomes warranting further consideration were identified in non-randomised studies. Where non-randomised studies observed possible harms, often no or few confounders were controlled for (moderate to high risk of bias), samples were small (200 babies or fewer), and/or results were from subgroup analyses. Limitations include missing data for important outcomes across most studies, heterogeneity of included studies, and inclusion of published data only.
CONCLUSIONS
Our findings do not support clear associations between antenatal magnesium sulphate for beneficial indications and adverse neonatal outcomes. Further large, high-quality studies (prospective cohorts or individual participant data meta-analyses) assessing specific outcomes, or the impact of regimen, pregnancy, or birth characteristics on these outcomes, would further inform safety recommendations.

Review
INTRODUCTION
The optimal dosing regimen of magnesium sulfate for treating preeclampsia and eclampsia is unclear. Evidence from the Cochrane review of randomized controlled trials (RCTs) was inconclusive due to lack of relevant data.
MATERIAL AND METHODS
To complement the evidence from the Cochrane review, we assessed available data from non-randomized studies on the comparative efficacy and safety of alternative magnesium sulfate regimens for the management of preeclampsia and eclampsia. Sources included Medline, EMBASE, Popline, CINAHL, Global Health Library, African Index Medicus, Biological abstract, BIOSIS and reference lists of eligible studies. We selected non-randomized study designs including quasi-RCTs, cohort, case-control and cross-sectional studies that compared magnesium sulfate regimens in women with preeclampsia or eclampsia.
RESULTS
Of 6178 citations identified, 248 were reviewed in full text and five studies of low to very low quality were included. Compared with standard regimens, lower-dose regimens appeared equally as good in terms of preventing seizures [odds ratio (OR) 1.02, 95% confidence interval (CI) 0.46-2.28, 899 women, four studies], maternal morbidity (OR 0.47, 95%CI 0.32-0.71, 796 women, three studies), and fetal and/or neonatal mortality (OR 0.87, 95%CI 0.38-2.00, 800 women, four studies). Comparison of loading dose only with maintenance dose regimens showed no differences in seizure rates (OR 0.99, 95%CI 0.22-4.50, 146 women, two studies), maternal morbidity (OR 0.53, 95%CI 0.15-1.93, 146 women, two studies), maternal mortality (OR 0.63, 95%CI 0.05-7.50, 146 women, two studies), and fetal and/or neonatal mortality (OR 0.49, 95%CI 0.23-1.03, 146 women, two studies).
CONCLUSION
Lower-dose and loading dose-only regimens could be as safe and efficacious as standard regimens; however, this evidence comes from low to very low quality studies and further high quality studies are needed.

BACKGROUND
Asthma is an illness that commonly affects adults and children, and it serves as a common reason for children to attend emergency departments. An asthma exacerbation is characterised by acute or subacute worsening of shortness of breath, cough, wheezing, and chest tightness and may be triggered by viral respiratory infection, poor compliance with usual medication, a change in the weather, or exposure to allergens or irritants. Most children with asthma have mild or moderate exacerbations and respond well to first-line therapy (inhaled short-acting beta-agonists and systemic corticosteroids). However, the best treatment for the small proportion of seriously ill children who do not respond to first-line therapy is not well understood. Currently, a large number of treatment options are available and there is wide variation in management.
OBJECTIVES
Main objective - To summarise Cochrane Reviews with or without meta-analyses of randomised controlled trials on the efficacy and safety of second-line treatment for children with acute exacerbations of asthma (i.e. after first-line treatments, titrated oxygen delivery, and administration of intermittent inhaled short-acting beta-agonists and oral corticosteroids have been tried and have failed) Secondary objectives - To identify gaps in the current evidence base that will inform recommendations for future research and subsequent Cochrane Reviews - To categorise information on reported outcome measures used in trials of escalation of treatment for acute exacerbations of asthma in children, and to make recommendations for development and reporting of standard outcomes in future trials and reviews - To identify relevant randomised controlled trials that have been published since the date of publication of each included review METHODS: We included Cochrane Reviews assessing interventions for children with acute exacerbations of asthma. We searched the Cochrane Database of Systematic Reviews. The search is current to 28 December 2019. We also identified trials that were potentially eligible for, but were not currently included in, published reviews. We assessed the quality of included reviews using the ROBIS criteria (tool used to assess risk of bias in systematic reviews). We presented an evidence synthesis of data from reviews alongside an evidence map of clinical trials. Primary outcomes were length of stay, hospital admission, intensive care unit admission, and adverse effects. We summarised all findings in the text and reported data for each outcome in 'Additional tables'.
MAIN RESULTS
We identified 17 potentially eligible Cochrane Reviews but extracted data from, and rated the quality of, 13 reviews that reported results for children alone. We excluded four reviews as one did not include any randomised controlled trials (RCTs), one did not provide subgroup data for children, and the last two had been updated and replaced by subsequent reviews. The 13 reviews included 67 trials; the number of trials in each review ranged from a single trial up to 27 trials. The vast majority of comparisons included between one and three trials, involving fewer than 100 participants. The total number of participants included in reviews ranged from 40 to 2630. All studies included children; 16 (24%) included children younger than two years of age. Most of the reviews reported search dates older than four years. We have summarised the published evidence as outlined in Cochrane Reviews. Key findings, in terms of our primary outcomes, are that (1) intravenous magnesium sulfate was the only intervention shown to reduce hospital length of stay (high-certainty evidence); (2) no evidence suggested that any intervention reduced the risk of intensive care admission (low- to very low-certainty evidence); (3) the risk of hospital admission was reduced by the addition of inhaled anticholinergic agents to inhaled beta-agonists (moderate-certainty evidence), the use of intravenous magnesium sulfate (high-certainty evidence), and the use of inhaled heliox (low-certainty evidence); (4) the addition of inhaled magnesium sulfate to usual bronchodilator therapy appears to reduce serious adverse events during hospital admission (moderate-certainty evidence); (5) aminophylline increased vomiting compared to placebo (moderate-certainty evidence) and increased nausea and nausea/vomiting compared to intravenous beta-agonists (low-certainty evidence); and (6) the addition of anticholinergic therapy to short-acting beta-agonists appeared to reduce the risk of nausea (high-certainty evidence) and tremor (moderate-certainty evidence) but not vomiting (low-certainty evidence). We considered 4 of the 13 reviews to be at high risk of bias based on the ROBIS framework. In all cases, this was due to concerns regarding identification and selection of studies. The certainty of evidence varied widely (by review and also by outcome) and ranged from very low to high.
AUTHORS' CONCLUSIONS
This overview provides the most up-to-date evidence on interventions for escalation of therapy for acute exacerbations of asthma in children from Cochrane Reviews of randomised controlled trials. A vast majority of comparisons involved between one and three trials and fewer than 100 participants, making it difficult to assess the balance between benefits and potential harms. Due to the lack of comparative studies between various treatment options, we are unable to make firm practice recommendations. Intravenous magnesium sulfate appears to reduce both hospital length of stay and the risk of hospital admission. Hospital admission is also reduced with the addition of inhaled anticholinergic agents to inhaled beta-agonists. However, further research is required to determine which patients are most likely to benefit from these therapies. Due to the relatively rare incidence of acute severe paediatric asthma, multi-centre research will be required to generate high-quality evidence. A number of existing Cochrane Reviews should be updated, and we recommend that a new review be conducted on the use of high-flow nasal oxygen therapy. Important priorities include development of an internationally agreed core outcome set for future trials in acute severe asthma exacerbations and determination of clinically important differences in these outcomes, which can then inform adequately powered future trials.

Review
INTRODUCTION
In resource-rich countries, the incidence of severe perinatal asphyxia (causing death or severe neurological impairment) is about 1/1000 live births. In resource-poor countries, perinatal asphyxia is probably much more common. Data from hospital-based studies in such settings suggest an incidence of 5-10/1000 live births.
METHODS AND OUTCOMES
We conducted a systematic review and aimed to answer the following clinical question: What are the effects of interventions in term or near-term newborns with perinatal asphyxia? We searched: Medline, Embase, The Cochrane Library and other important databases up to June 2006 (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 25 systematic reviews, RCTs or observational 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: anticonvulsants (prophylactic), antioxidants, calcium channel blockers, corticosteroids, fluid restriction, head and/or whole body hypothermia, hyperbaric oxygen treatment, hyperventilation, Iinotrope support, magnesium sulphate, mannitol, opiate antagonists, and resuscitation (in air versus higher concentrations of oxygen).

Meta-Analysis Review
STUDY OBJECTIVE
Emergence agitation (EA) is a common complication in pediatric patients after general anesthesia. The effectiveness of magnesium sulfate in decreasing the incidence of EA in children remains controversial. Therefore, a systematic review and meta-analysis was performed to assess the efficacy of magnesium sulfate in preventing EA in pediatric patients following general anesthesia.
DESIGN
Systematic review and meta-analysis.
SETTING
PubMed, Embase, Web of Science, and Cochrane Library were searched to identify eligible randomized controlled trials from their respective database inception dates to June 30, 2021.
PATIENTS
Pediatric patients (< 18 years old) undergoing general anesthesia.
INTERVENTIONS
Intravenous administration of magnesium sulfate.
MEASUREMENTS
The primary outcome of the meta-analysis was EA incidence. The risk of bias of the included studies was evaluated using the revised Cochrane risk of bias tool for randomized trials (RoB 2.0). Grading of Recommendations, Assessment, Development, and Evaluation was applied to assess the level of certainty.
MAIN RESULTS
Eight studies with 635 participants were identified. The forest plot revealed no significant difference in the incidence of EA between patients treated with magnesium sulfate and the control group (risk ratio = 0.69, 95% confidence interval [0.44, 1.07]; P = 0.10, I = 74%, moderate level of certainty). Additionally, magnesium sulfate did not reduce postoperative pediatric anesthesia emergence delirium scores but prolonged the emergence time. No significant differences were observed in postoperative complications (nausea, vomiting, laryngospasm, breath-holding, coughing, oxygen desaturation, and cardiac arrhythmias).
CONCLUSIONS
Administration of magnesium sulfate during general anesthesia did not affect the occurrence of EA in pediatric patients. However, magnesium sulfate can prolong the emergence time without adverse effects. PROSPERO registration number: CRD42021252924.

INTRODUCTION
Magnesium sulfate has been extensively used to treat asthma exacerbations, but its efficacy remains questionable in the chronic obstructive pulmonary disease (COPD) population. The aim of the study was to compare the efficacy of intravenous (IV) magnesium sulfate in COPD. A systemic review search was conducted on PubMed, Embase, and the Central Cochrane Registry. Randomized clinical trials were included with magnesium sulfate as an intervention arm in the COPD population.
MATERIALS AND METHODS
For continuous variables, standardized mean difference (SMD) and difference in means (MD) were calculated. For discrete variables, the Mantel-Haenszel (MH) odds ratio was used. For effect sizes, a confidence interval of 95% was used. A p-value of less than 0.05 was used for statistical significance. Analysis was done using both random and fixed effect models. Heterogeneity was evaluated using the I² statistic.
RESULTS
Seven studies were included in the final analysis. In patients with acute exacerbations of COPD treated with IV magnesium, a significant increase in forced expiratory volume in one second (FEV₁) was observed (MD = 2.537 [0.717 to 4.357], p = 0.006), as well as in peak expiratory flow rate (PEFR) (SMD = 1.073 [0.748 to 1.397], p < 0.001) using the fixed model. Similarly, residual volume decreased significantly in the IV magnesium group (MD = -0.470 [-0.884 to -0.056], p = 0.026). The hospitalization rate was also lower in the magnesium group, (MH odds ratio 0.453 [0.233 to 0.882], p = 0.020). No statistically significant difference was noted in FEV₁ in the stable COPD population.
CONCLUSION
IV magnesium was associated with a favorable deviation of FEV1 and PEFR, decreased residual volume, and decreased odds of admission in the COPD exacerbation population. Therefore, magnesium sulfate can be used as an adjunctive therapy in the treatment of acute exacerbations of COPD.

Background Magnesium sulfate is an accepted intervention for fetal neuroprotection. There are some perceived differences in the international recommendations on the use magnesium sulfate for fetal neuroprotection in preterm labor. Content This systematic review analyses the available clinical guidelines for the use of magnesium sulfate for fetal neuroprotection and compares the recommendations, and assesses the quality of guidelines. This provides the consensus, differences and explores the areas for future collaborative research. We searched databases of PUBMED, EMBASE, COCHRANE, Web of Science, LILACS; and included the national and the international clinical practice guidelines. We included seven guidelines out of 227 search results. We evaluated the methodological quality of guidelines using the Appraisal of Guidelines Research and Evaluation (AGREE II) tool and systematically extracted guideline characters, recommendation and supporting evidence base. Summary Five guidelines were of high quality and two were of moderate quality. One guideline achieved more than an 80% score in all the domains of AGREE II tool. All guidelines recommend use of magnesium sulfate for fetal neuroprotection. However, there are differences in other recommendations such as upper gestational age, dose, duration, repeating treatment and use of additional tocolytics. Outlook Future guidelines should include recommendations on all aspects of magnesium sulfate therapy for fetal neuroprotection. Future research and international collaboration should focus on areas where there are no international consensual recommendations.

Review
INTRODUCTION
Acetylcholinesterase inhibition by organophosphorus pesticides or organophosphate nerve agents can cause acute parasympathetic system dysfunction, muscle weakness, seizures, coma, and respiratory failure. Prognosis depends on the dose and relative toxicity of the specific compound, as well as pharmacokinetic factors.
METHODS AND OUTCOMES
We conducted a systematic review and aimed to answer the following clinical question: What are the effects of treatments for acute organophosphorus poisoning? We searched: Medline, Embase, The Cochrane Library, and other important databases up to April 2010 (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 62 systematic reviews, RCTs, or observational 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: activated charcoal (single or multiple doses), alpha(2) adrenergic receptor agonists, atropine, benzodiazepines, butyrylcholinesterase replacement therapy, cathartics, extracorporeal clearance, gastric lavage, glycopyrronium bromide (glycopyrrolate), ipecacuanha (ipecac), magnesium sulphate, milk or other home remedy immediately after ingestion, N-methyl-D-aspartate receptor antagonists, organophosphorus hydrolases, oximes, removing contaminated clothes and washing the poisoned person, and sodium bicarbonate.

Review
Stroke is a leading cause of death, disability, and dementia worldwide. Strokes can be divided into ischemic strokes and hemorrhagic strokes. At the moment, tissue plasminogen activator (tPA) is the only FDA-approved drug for ischemic stroke. Minocycline (MC) and Magnesium (Mg) are promising therapies for ischemic stroke, especially in the pre-hospital setting. These drugs are readily available, inexpensive, and generally safe. We decided to investigate these drugs' neuroprotective effects in treating ischemic stroke in the acute and chronic setting. We conducted a systematic review of the published literature on MC and Mg's functional outcome in ischemic stroke. This paper's methodology included only clinical trials published in the last 15 years, using PubMed as a database. The systematic review demonstrated that MC infusion in the pre-hospital and hospital setting improved functional outcomes and disability scores. Furthermore, MC also decreased matrix metalloproteinase 9 (MMP-9) levels. MC might have a more significant effect on men than women because different molecular pathways of cerebral ischemia seem to be involved between both genders. The systematic review showed that patients with ischemic stroke did not benefit from magnesium sulfate infusion in the pre-hospital and hospital setting. Nevertheless, patients with lacunar strokes and patients who supplemented their meals with potassium-magnesium salt in the diet had better functional outcomes. Future studies would need a more significant sample of participants and a better selection to increase the study's power and avoid selection bias, respectively. Further publications could benefit from subcategorizing strokes and investigating the gender role in stroke treatment. These directives could give a more robust conclusion regarding the neuroprotective effects of these drugs.

Review
INTRODUCTION
About 10% of adults have suffered an attack of asthma, and up to 5% of these have severe disease that responds poorly to treatment. Patients with severe disease have an increased risk of death, but patients with mild-to-moderate disease are also at risk of exacerbations. Most guidelines about the management of asthma follow stepwise protocols. This review does not endorse or follow any particular protocol, but presents the evidence about specific interventions.
METHODS AND OUTCOMES
We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of treatments for chronic asthma? What are the effects of treatments for acute asthma? We searched: Medline, Embase, The Cochrane Library, and other important databases up to June 2008 (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 99 systematic reviews, RCTs, or observational 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. For acute asthma: beta(2) agonists (plus ipratropium bromide, pressured metered-dose inhalers, short-acting continuous nebulised, short-acting intermittent nebulised, and short-acting intravenous); corticosteroids (inhaled); corticosteroids (single oral, combined inhaled, and short courses); education about acute asthma; generalist care; helium-oxygen mixture (heliox); magnesium sulphate (intravenous and adding isotonic nebulised magnesium to inhaled beta(2) agonists); mechanical ventilation; oxygen supplementation (controlled 28% oxygen and controlled 100% oxygen); and specialist care. For chronic asthma: beta(2) agonists (adding long-acting inhaled beta(2) agonists when asthma is poorly controlled by inhaled corticosteroids, or short-acting inhaled beta(2) agonists as needed for symptom relief); inhaled corticosteroids (low dose and increasing dose); leukotriene antagonists (with or without inhaled corticosteroids); and theophylline (when poorly controlled by inhaled corticosteroids).
