Meta-Analysis Review
AIM
We performed a systematic review and network meta-analysis (NMA) to obtain comparative effectiveness estimates and rankings of non-surgical interventions used to treat infantile spasms.
METHOD
All randomized controlled trials (RCTs) including children 2 months to 3 years of age with infantile spasms (with hypsarrhythmia or hypsarrhythmia variants on electroencephalography) receiving appropriate first-line medical treatment were included. Electroclinical and clinical remissions within 1 month of starting treatment were analyzed.
RESULTS
Twenty-two RCTs comparing first-line treatments for infantile spasms were reviewed; of these, 17 were included in the NMA. Both frequentist and Bayesian network rankings for electroclinical remission showed that high dose adrenocorticotropic hormone (ACTH), methylprednisolone, low dose ACTH and magnesium sulfate (MgSO ) combination, low dose ACTH, and high dose prednisolone were most likely to be the 'best' interventions, although these were not significantly different from each other. For clinical remission, low dose ACTH/MgSO combination, high dose ACTH (with/without vitamin B ), high dose prednisolone, and low dose ACTH were 'best'.
INTERPRETATION
Treatments including ACTH and high dose prednisolone are more effective in achieving electroclinical and clinical remissions for infantile spasms.
WHAT THIS PAPER ADDS
Adrenocorticotropic hormone and high dose prednisolone are more effective than other medications for infantile spasms. Symptomatic etiology decreases the likelihood of remission even after adjusting for treatment lag.

European Journal of Anaesthesiology Oct 2023Pain after craniotomy can be intense and its management is often suboptimal.
BACKGROUND
Pain after craniotomy can be intense and its management is often suboptimal.
OBJECTIVES
We aimed to evaluate the available literature and develop recommendations for optimal pain management after craniotomy.
DESIGN
A systematic review using procedure-specific postoperative pain management (PROSPECT) methodology was undertaken.
DATA SOURCES
Randomised controlled trials and systematic reviews published in English from 1 January 2010 to 30 June 2021 assessing pain after craniotomy using analgesic, anaesthetic or surgical interventions were identified from MEDLINE, Embase and Cochrane Databases.
ELIGIBILITY CRITERIA
Each randomised controlled trial (RCT) and systematic review was critically evaluated and included only if met the PROSPECT requirements. Included studies were evaluated for clinically relevant differences in pain scores, use of nonopioid analgesics, such as paracetamol and NSAIDs, and current clinical relevance.
RESULTS
Out of 126 eligible studies identified, 53 RCTs and seven systematic review or meta-analyses met the inclusion criteria. Pre-operative and intra-operative interventions that improved postoperative pain were paracetamol, NSAIDs, intravenous dexmedetomidine infusion, regional analgesia techniques, including incision-site infiltration, scalp nerve block and acupuncture. Limited evidence was found for flupirtine, intra-operative magnesium sulphate infusion, intra-operative lidocaine infusion, infiltration adjuvants (hyaluronidase, dexamethasone and α-adrenergic agonist added to local anaesthetic solution). No evidence was found for metamizole, postoperative subcutaneous sumatriptan, pre-operative oral vitamin D, bilateral maxillary block or superficial cervical plexus block.
CONCLUSIONS
The analgesic regimen for craniotomy should include paracetamol, NSAIDs, intravenous dexmedetomidine infusion and a regional analgesic technique (either incision-site infiltration or scalp nerve block), with opioids as rescue analgesics. Further RCTs are required to confirm the influence of the recommended analgesic regimen on postoperative pain relief.

OBJECTIVES
Magnesium sulfate is a second-tier therapy for asthma exacerbations in children; guidelines recommend a single-dose to improve pulmonary function and decrease the odds of admission to the in-patient setting. However, many clinicians utilize prolonged magnesium sulfate infusions for children with refractory asthma. The purpose of this review is to describe the efficacy and safety of magnesium sulfate infusions administered over ≥ 1 h in children with status asthmaticus.
METHODS
Medline was searched using the keywords "magnesium sulfate" and "children." Articles evaluating the use of magnesium sulfate infusions for ≥1 h published between 1946 and August 2021 were included. Published abstracts were not included because of lack of essential details. All articles were screened by two reviewers.
RESULTS
Eight reports including 447 children were included. The magnesium regimens evaluated included magnesium delivered over 1 h ( = 148; 33.1%), over 4-5 h ( = 105; 23.5%), and over >24 h ( = 194; 43.4%). Majority of patients received a bolus dose of 25-75 mg/kg/dose prior to initiation of a prolonged infusion ( = 299; 66.9%). For the patients receiving magnesium infusions over 4-5 h, the dosing regimen varied between 40 and 50 mg/kg/h. For those receiving magnesium infusions >24 h, the dosing varied between 18.4 and 25 mg/kg/h for a duration between 53.4 and 177.5 h. Only three reports including 186 patients (41.6%) included an evaluation of clinical outcomes including evaluation of lung function parameters, reduction in PICU transfers, and/or decrease in emergency department length of stay. Five reports including 261 patients (58.4%) evaluated magnesium serum concentrations. In most reports, the goal concentrations were between 4 and 6 mg/dL. Only 3 (1.1%) out of the 261 patients had supratherapeutic magnesium concentrations. The only reports finding adverse events attributed to magnesium were noted in those receiving infusions for >24 h. Clinically significant adverse events included hypotension ( = 74; 16.6%), nausea/vomiting ( = 35; 7.8%), mild muscle weakness ( = 22; 4.9%), flushing ( = 10; 2.2%), and sedation ( = 2; 0.4%).
CONCLUSION
Significant variability was noted in magnesium dosing regimens, with most children receiving magnesium infusions over >4 h. Most reports did not assess clinical outcomes. Until future research is conducted, the use of prolonged magnesium sulfate infusions should be reserved for refractory asthma therapy.

Tetanus is a rare life-threatening condition often complicated by repetitive spasms, dysautonomia and neuromuscular respiratory failure contributing to high fatality rates in its severe form. Benzodiazepines used to treat muscle spasms pose a high risk of respiratory failure requiring mechanical ventilation, which is unaffordable and inaccessible for many. Magnesium sulfate, a cheap and widely available medication in all urban and rural health centres of LMICs for the treatment of eclampsia, can be used to control muscle spasms and dysautonomia. We thus conducted a systematic review of evidence to assess the safety and efficacy of magnesium sulfate in the treatment of tetanus. Any study published before April 15, 2021, discussing the efficacy and/or safety of MgSO4 infusion in the treatment of tetanus was systemically reviewed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Our systematic review included data from 13 studies, three were randomised, double-blind and controlled trials. The remaining ten studies were observational; six prospective and four retrospective studies. Our review showed no mortality benefit associated with the use of magnesium sulfate. However, magnesium sulfate was found to be effective in reducing spasms along with diazepam, leading to better control of dysautonomia, reduced need for mechanical ventilation and shorter hospital stay by 3-7 days. The incidence of magnesium toxicity was very low in the studies included.

Meta-Analysis Review
PURPOSE
Magnesium sulfate (MgSO) has been widely used in obstetrics as a mean to help decrease maternal and neonatal morbidity in various antenatal pathology. As a factor, it seems to regulate immunity and can, thus, predispose to infectious morbidity. To date, it remains unknown if its administration can increase the risk of chorioamnionitis. In the present meta-analysis, we sought to accumulate the available evidence.
METHODS
We systematically searched Medline, Scopus, Clinicaltrials.gov, EMBASE, Cochrane Central Register of Controlled Trials CENTRAL, and Google Scholar databases in our primary search along with the reference lists of electronically retrieved full-text papers.
RESULTS
Eight studies were included that investigated the incidence of chorioamnionitis among parturient that received MgSO and control patients. Magnesium sulfate was administered in 3229 women and 3330 women served as controls as they did not receive MgSO. The meta-analysis of data revealed that there was no association between the administration of magnesium sulfate and the incidence of chorioamnionitis (OR 0.98, 95% CI 0.73, 1.32). Rucker's analysis revealed that small studies did not significantly influence the statistical significance of this finding (OR 1.12, 95% CI 0.82, 1.53). Trial sequential analysis revealed that the required number to safely interpret the primary outcome was not reached. Two studies evaluated the impact of MgSO in neonates delivered in the setting of chorioamnionitis. Neither of these indicated the presence of a beneficial effect in neonatal morbidity, including the risk of cerebral palsy, intraventricular hemorrhage, necrotizing enterocolitis, bronchopulmonary dysplasia, sepsis, stillbirth, or neonatal death.
CONCLUSION
Current evidence indicates that magnesium sulfate is not associated with an increased risk of maternal chorioamnionitis. However, it should be noted that its effect on neonatal outcomes of offspring born in the setting of chorioamnionitis might be subtle if any, although the available evidence is very limited.

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 overview does not endorse or follow any particular protocol, but presents the evidence about a specific intervention, magnesium sulfate.
METHODS AND OUTCOMES
We conducted a systematic overview, aiming to answer the following clinical question: What are the effects of magnesium sulfate for acute asthma? We searched: Medline, Embase, The Cochrane Library, and other important databases up to November 2014 (Clinical Evidence overviews are updated periodically; please check our website for the most up-to-date version of this overview).
RESULTS
At this update, searching of electronic databases retrieved 50 studies. After deduplication and removal of conference abstracts, 24 records were screened for inclusion in the overview. Appraisal of titles and abstracts led to the exclusion of 10 studies and the further review of 14 full publications. Of the 14 full articles evaluated, one systematic review was updated and one systematic review was added at this update. We performed a GRADE evaluation for five PICO combinations.
CONCLUSIONS
In this systematic overview, we categorised the efficacy for two comparisons based on information about the effectiveness and safety of magnesium sulfate (iv) versus placebo and magnesium sulfate (nebulised) plus short-acting beta2 agonists (inhaled) versus short-acting beta2 agonists (inhaled) alone.

Review
BACKGROUND
Asthma is the common chronic inflammatory disease affecting children. It is usually associated with airway hyper-responsiveness. Globally, the prevalence of asthma among pediatrics population varies from 10% to 30%. Its symptoms range from chronic cough to life-threatening bronchospasm. At emergency department, all patients with acute severe asthma should initially receive oxygen, nebulized β2-agonists, nebulized anticholinergic agent, and corticosteroids. Though bronchodilators act within minutes, corticosteroids may require hours. Magnesium sulphate (MgSO) was first considered for treating asthma about 60 years ago. Several case reports were published on its usefulness in decreasing admission and endotracheal intubation. So far, evidence is conflicting to fully employ MgSO for asthma management in children under five.
OBJECTIVE
This systematic review was aimed to evaluate the effectiveness and safety of MgSO in the treatment of severe acute asthmatic attacks in children.
METHODS
A systematic and comprehensive search of literature was performed to identify controlled clinical trials conducted on IV and nebulized MgSO in pediatric patients with acute asthma.
RESULTS
Data generated from three randomized clinical trials were included in the final analysis. In this analysis, intravenous MgSO did not improve respiratory function (RR=1.09, 95%CI: 0.81-1.45) and not safer than conventional treatment (RR=0.38, 95%CI: 0.08-1.67). Similarly, use of nebulized MgSO showed no significant effect on respiratory function (RR=1.05, 95%CI: 0.68-1.64) and more tolerable (RR=0.31, 95%CI: 0.14-0.68).
CONCLUSION
Intravenous MgSO may not be superior to conventional treatment in moderate to severe acute asthma among children and neither have significant adverse effects. Similarly, nebulized MgSO showed no significant effect on respiratory function in moderate to severe acute asthma in children under five but it seems a safer alternative.

Review
AIM
Economic appraisal can help guide policy-making for purchasing decisions, and treatment and management algorithms for health interventions. We conducted a systematic review of economic studies in cerebral palsy (CP) to inform future research.
METHOD
Economic studies published since 1970 were identified from seven databases. Two reviewers independently screened abstracts and extracted data following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Any discrepancies were resolved by discussion.
RESULTS
Of 980 identified references, 115 were included for full-text assessment. Thirteen articles met standard criteria for a full economic evaluation, two as partial economic evaluations, and 18 as cost studies. Six were full economic evaluations alongside clinical studies or randomized controlled trials, whereas seven involved modelling simulations. The economic case for administration of magnesium sulfate for imminent preterm birth is compelling, achieving both health gain and cost savings. Current literature suggests intrathecal baclofen therapy and botulinum toxin injection are cost-effective, but stronger evidence for long-term effects is needed. Lifestyle and web-based interventions are inexpensive, but broader measurement of outcomes is required.
INTERPRETATION
Prevention of CP would avoid significant economic burden. Some treatments and interventions have been shown to be cost-effective, although stronger evidence of clinical effectiveness is needed. What this paper adds Cost-effectiveness evidence shows prevention is the most significant strategy. Some treatments are cost-effective, but stronger evidence for long-term effectiveness is required. Comparison of treatment costs is challenging owing to variations in methodologies and varying clinical indications.

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.

Review
BACKGROUND
Creatine is an amino acid derivative and, when phosphorylated (phosphocreatine), is involved in replenishing adenosine triphosphate (ATP) via the creatine kinase reaction. Cells obtain creatine from a diet rich in fish, meat, or dairy and by endogenous synthesis from the amino acids arginine, glycine, and methionine in an approximate 50:50 ratio. Animal studies have shown that creatine may provide fetal neuroprotection when given to the mother through her diet in pregnancy. It is important to assess whether maternally administered creatine in human pregnancy (at times of known, suspected, or potential fetal compromise) may offer neuroprotection to the fetus and may accordingly reduce the risk of adverse neurodevelopmental outcomes, such as cerebral palsy and associated impairments and disabilities arising from fetal brain injury.
OBJECTIVES
To assess the effects of creatine when used for neuroprotection of the fetus.
SEARCH METHODS
We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 November 2014).
SELECTION CRITERIA
We planned to include all published, unpublished, and ongoing randomised trials and quasi-randomised trials. We planned to include studies reported as abstracts only as well as full-text manuscripts. Trials using a cross-over or cluster-randomised design were not eligible for inclusion.We planned to include trials comparing creatine given to women in pregnancy for fetal neuroprotection (regardless of the route, timing, dose, or duration of administration) with placebo, no treatment, or with an alternative agent aimed at providing fetal neuroprotection. We also planned to include comparisons of different regimens for administration of creatine.
DATA COLLECTION AND ANALYSIS
We identified no completed or ongoing randomised controlled trials.
MAIN RESULTS
We found no randomised controlled trials for inclusion in this review.
AUTHORS' CONCLUSIONS
As we did not identify any randomised controlled trials for inclusion in this review, we are unable to comment on implications for practice. Although evidence from animal studies has supported a fetal neuroprotective role for creatine when administered to the mother during pregnancy, no trials assessing creatine in pregnant women for fetal neuroprotection have been published to date. If creatine is established as safe for the mother and her fetus, research efforts should first be directed towards randomised trials comparing creatine with either no intervention (ideally using a placebo), or with alternative agents aimed at providing fetal neuroprotection (including magnesium sulphate for the very preterm infant). If appropriate, these trials should then be followed by studies comparing different creatine regimens (dosage and duration of exposure). Such trials should be high quality and adequately powered to evaluate maternal and infant short and longer-term outcomes (including neurodevelopmental disabilities such as cerebral palsy), and should consider utilisation/costs of health care.
