Meta-Analysis Review
BACKGROUND
Traditionally, reversal of neuromuscular blocking agents following the completion of surgery was achieved with cholinesterase inhibitors. Recently, sugammadex has been increasingly relied upon. Sugammadex is a γ-cyclodextrin molecule that rapidly reverses steroidal neuromuscular blocking drugs. Its use following colorectal surgery has become more common, and while the rapidity of reversal is undoubtedly improved, whether sugammadex impacts clinical postoperative outcomes is unknown. This systematic review and meta-analysis aims to compare postoperative outcomes in patients receiving sugammadex to those receiving a control during colorectal surgery.
METHODS
Medline, Embase, and CENTRAL were systematically searched. Articles were included if they compared sugammadex with a control (e.g., neostigmine, pyridostigmine, placebo) in patients undergoing colorectal surgery in terms of total hospital length of stay and frequency of postoperative adverse respiratory events. Pairwise meta-analyses using inverse variance random effects was performed.
RESULTS
From 269 citations, five studies with 535 patients receiving sugammadex (45.8% female; mean age: 64.4) and 569 patients receiving a control (45.0% female; mean age: 64.3) were included. There was no significant difference in length of stay between the two groups (MD -0.01, 95% CI -0.27 to 0.25, P = 0.95). The risk of adverse respiratory events postoperatively was similar between the two groups (RR 1.33, 95% CI 0.81-2.19, P = 0.25).
CONCLUSION
There are no current data to suggest an improvement in postoperative outcomes with the use of sugammadex in patients undergoing colorectal surgery. This study is limited by the number of included studies. Further prospective studies comparing sugammadex and a control in colorectal surgery is required.

Review
This review provides an up-to-date literature account on the efficacy of Botulinum toxin treatment for common motor disorders of Parkinson Disease. The reviewed disorders include the common motor disorders in PD such as tremor, focal foot dystonia, rigidity and freezing of gait (FOG). In the area of Parkinson tremor, two newly described evaluation/injection techniques (Yale method in USA and Western University method in Canada) offer efficacy with low incidence of hand and finger weakness as side effects. Blinded studies conducted on foot dystonia of PD indicate that botulinum toxin injections into toe flexors are efficacious in alleviating this form of dystonia. Small, blinded studies suggest improvement of Parkinson rigidity after botulinum toxin injection; proof of this claim, however, requires information from larger, blinded clinical trials. In FOG, the improvement reported in open label studies could not be substantiated in blinded investigations. However, there is room for further controlled studies that include the proximal lower limb muscles in the injection plan and/or use higher doses of the injected toxin for this indication.

Meta-Analysis
BACKGROUND
Epidemiological studies have reported associations between pesticide exposure and respiratory health effects, but the quantitative impact on lung function is unclear. To fill this gap, we undertook a systematic review of the available literature on the association between pesticide exposure and pulmonary function.
AIMS
To examine all available literature regarding the relationship between occupational and environmental exposure to pesticides and lung function.
METHODS
We searched MEDLINE, EMBASE and Web of Science databases to 1 October 2017 without any date or language restrictions using a combination of MeSH terms and free text for 'pesticide exposure' and 'lung function'. We included studies that met the criteria of our research protocol registered in PROSPERO, and we assessed their quality using a modified Newcastle-Ottawa scale.
RESULTS
Of 2356 articles retrieved, 56 articles were included in the systematic review and pooled in meta-analyses for forced expiratory volume in 1 s (FEV1)/forced vital capacity (FVC), FVC and FEV1. There was tentative evidence that exposure to cholinesterase (ChE) inhibiting pesticides reduced FEV1/FVC and no evidence that paraquat exposure affected lung function in farmers.
CONCLUSIONS
Respiratory surveillance should be enhanced in those exposed to ChE-inhibiting pesticides which reduced FEV1/FVC according to the meta-analysis. Our study is limited by heterogeneity between studies due to different types of exposure assessment to pesticides and potential confounders. Further studies with a more accurate exposure assessment are suggested.

Meta-Analysis
BACKGROUND
As people age, they accumulate several health conditions, requiring the use of multiple medications (polypharmacy) to treat them. One of the challenges with polypharmacy is the associated increase in anticholinergic exposure to older adults. In addition, several studies suggest an association between anticholinergic burden and declining physical function in older adults.
OBJECTIVE/PURPOSE
This systematic review aimed to synthesise data from published studies regarding the association between anticholinergic burden and mobility. The studies were critically appraised for the strength of their evidence.
METHODS
A systematic literature search was conducted across five electronic databases, EMBASE, CINAHL, PSYCHINFO, Cochrane CENTRAL and MEDLINE, from inception to December 2021, to identify studies on the association of anticholinergic burden with mobility. The search was performed following a strategy that converted concepts in the PECO elements into search terms, focusing on terms most likely to be found in the title and abstracts of the studies. For observational studies, the risk of bias was assessed using the Newcastle Ottawa Scale, and the Cochrane risk of bias tool was used for randomised trials. The GRADE criteria was used to rate confidence in evidence and conclusions. For the meta-analyses, we explored the heterogeneity using the Q test and I test and the publication bias using the funnel plot and Egger's regression test. The meta-analyses were performed using Jeffreys's Amazing Statistics Program (JASP).
RESULTS
Sixteen studies satisfied the inclusion criteria from an initial 496 studies. Fifteen studies identified a significant negative association of anticholinergic burden with mobility measures. One study did not find an association between anticholinergic intervention and mobility measures. Five studies included in the meta-analyses showed that anticholinergic burden significantly decreased walking speed (0.079 m/s ± 0.035 MD ± SE,95% CI: 0.010 to 0.149, p = 0.026), whilst a meta-analysis of four studies showed that anticholinergic burden significantly decreased physical function as measured by three variations of the Instrumental Activities of Daily Living (IADL) instrument 0.27 ± 0.12 (SMD ± SE,95% CI: 0.03 to 0.52), p = 0.027. The results of both meta-analyses had an I statistic of 99% for study heterogeneity. Egger's test did not reveal publication bias.
CONCLUSION
There is consensus in published literature suggesting a clear association between anticholinergic burden and mobility. Consideration of cognitive anticholinergic effects may be important in interpreting results regarding the association of anticholinergic burden and mobility as anticholinergic drugs may affect mobility through cognitive effects.

Review
PURPOSE
Asthma is a heterogeneous disease with a wide range of symptoms. Severe asthma exacerbations (SAEs) are characterized by worsening symptoms and bronchospasm requiring emergency department visits. In addition to conventional strategies for SAEs (inhaled β-agonists, anticholinergics, and systemic corticosteroids), another pharmacological option is represented by ketamine. We performed a systematic review to explore the role of ketamine in refractory SAEs.
METHODS
We performed a systematic search on PubMed and EMBASE up to August 12th, 2021. We selected prospective studies only, and outcomes of interest were oxygenation/respiratory parameters, clinical status, need for invasive ventilation and effects on weaning.
RESULTS
We included a total of seven studies, five being randomized controlled trials (RCTs, population range 44-92 patients). The two small prospective studies (n = 10 and n = 11) did not have a control group. Four studies focused on adults, and three enrolled a pediatric population. We found a large heterogeneity regarding sample size, age and gender distribution, inclusion criteria (different severity scores, if any) and ketamine dosing (bolus and/or continuous infusion). Of the five RCTs, three compared ketamine to placebo, while one used fentanyl and the other aminophylline. The outcomes evaluated by the included studies were highly variable. Despite paucity of data and large heterogeneity, an overview of the included studies suggests absence of clear benefit produced by ketamine in patients with refractory SAE, and some signals towards side effects.
CONCLUSION
Our systematic review does not support the use of ketamine in refractory SAE. A limited number of prospective studies with large heterogeneity was found. Well-designed multicenter RCTs are desirable.

Review
BACKGROUND
Respiratory disease is the main cause of morbidity and mortality in cystic fibrosis (CF), and many different therapies are used by people with CF in the management of respiratory problems. Bronchodilator therapy is used to relieve symptoms of shortness of breath and to open the airways to allow clearance of mucus. Despite the widespread use of inhaled bronchodilators in CF, there is little objective evidence of their efficacy. A Cochrane Review looking at both short- and long-acting inhaled bronchodilators for CF was withdrawn from the Cochrane Library in 2016. That review has been replaced by two separate Cochrane Reviews: one on long-acting inhaled bronchodilators for CF, and this review on short-acting inhaled bronchodilators for CF. For this review 'inhaled' includes the use of pressurised metered dose inhalers (MDIs), with or without a spacer, dry powder devices and nebulisers.
OBJECTIVES
To evaluate short-acting inhaled bronchodilators in children and adults with CF in terms of clinical outcomes and safety.
SEARCH METHODS
We searched the Cochrane Cystic Fibrosis Trials Register, compiled from electronic database searches and handsearching of journals and conference abstract books on 28 March 2022 and searched trial registries for any new or ongoing trials on 12 April 2022. We also searched the reference lists of relevant articles and reviews.
SELECTION CRITERIA
We searched for randomised controlled trials (RCTs) or quasi-RCTs that looked at the effect of any short-acting inhaled bronchodilator delivered by any device, at any dose, at any frequency and for any duration compared to either placebo or another short-acting inhaled bronchodilator in people with CF. We screened references as per standard Cochrane methodology.
DATA COLLECTION AND ANALYSIS
Two review authors extracted data and assessed risk of bias using the Cochrane RoB 1 tool. Where we were not able to enter data into our analyses we reported results directly from the papers. We assessed the certainty of evidence using GRADE.
MAIN RESULTS
We included 11 trials from our systematic search, with 191 participants meeting our inclusion criteria; three of these trials had three treatment arms. Eight trials compared short-acting inhaled beta-2 agonists to placebo and four trials compared short-acting inhaled muscarinic antagonists to placebo. Three trials compared short-acting inhaled beta-2 agonists to short-acting inhaled muscarinic antagonists. All were cross-over trials with only small numbers of participants. We were only able to enter data into the analysis from three trials comparing short-acting inhaled beta-2 agonists to placebo. Short-acting inhaled beta-2 agonists versus placebo All eight trials (six single-dose trials and two longer-term trials) reporting on this comparison reported on forced expiratory volume in 1 second (FEV), either as per cent predicted (% predicted) or L. We were able to combine the data from two trials in a meta-analysis which showed a greater per cent change from baseline in FEV L after beta-2 agonists compared to placebo (mean difference (MD) 6.95%, 95% confidence interval (CI) 1.88 to 12.02; 2 trials, 82 participants). Only one of the longer-term trials reported on exacerbations, as measured by hospitalisations and courses of antibiotics. Only the second longer-term trial presented results for participant-reported outcomes. Three trials narratively reported adverse events, and these were all mild. Three single-dose trials and the two longer trials reported on forced vital capacity (FVC), and five trials reported on peak expiratory flow, i.e. forced expiratory flow between 25% and 75% (FEF). One trial reported on airway clearance in terms of sputum weight. We judged the certainty of evidence for each of these outcomes to be very low, meaning we are very uncertain about the effect of short-acting inhaled beta-2 agonists on any of the outcomes we assessed. Short-acting inhaled muscarinic antagonists versus placebo All four trials reporting on this comparison looked at the effects of ipratropium bromide, but in different doses and via different delivery methods. One trial reported FEV % predicted; three trials measured this in L. Two trials reported adverse events, but these were few and mild. One trial reported FVC and three trials reported FEF. None of the trials reported on quality of life, exacerbations or airway clearance. We judged the certainty of evidence for each of these outcomes to be very low, meaning we are very uncertain about the effect of short-acting inhaled muscarinic antagonists on any of the outcomes we assessed. Short-acting inhaled beta-2 agonists versus short-acting inhaled muscarinic antagonists None of the three single-dose trials reporting on this comparison provided data we could analyse. The original papers from three trials report that both treatments lead to an improvement in FEV L. Only one trial reported on adverse events; but none were experienced by any participant. No trial reported on any of our other outcomes. We judged the certainty of evidence to be very low, meaning we are very uncertain about the effect of short-acting inhaled beta-2 agonists compared to short-acting inhaled muscarinic antagonists on any of the outcomes we assessed.
AUTHORS' CONCLUSIONS
All included trials in this review are small and of a cross-over design. Most trials looked at very short-term effects of inhaled bronchodilators, and therefore did not measure longer-term outcomes. The certainty of evidence across all outcomes was very low, and therefore we have been unable to describe any effects with certainty.

Meta-Analysis Review
BACKGROUND
Varenicline is an efficacious smoking-cessation drug. However, previous meta-analyses provide conflicting results regarding its cardiovascular safety. The publication of several new randomized controlled trials (RCTs) provides an opportunity to reassess this potential adverse drug reaction.
METHODS AND RESULTS
We searched MEDLINE, EMBASE, and the Cochrane Library for RCTs that compare varenicline with placebo for smoking cessation. RCTs reporting cardiovascular serious adverse events and/or all-cause mortality during the treatment period or within 30 days of treatment discontinuation were eligible for inclusion. Relative risks (RRs) with 95% CIs were generated by using DerSimonian-Laird random-effects models. Thirty-eight RCTs met our inclusion criteria (N=12 706). Events were rare in both varenicline (57/7213) and placebo (43/5493) arms. No difference was observed for cardiovascular serious adverse events when comparing varenicline with placebo (RR 1.03, 95% CI 0.72-1.49). Similar findings were obtained when examining cardiovascular (RR 1.04, 95% CI 0.57-1.89) and noncardiovascular patients (RR 1.03, 95% CI 0.64-1.64). Deaths were rare in both varenicline (11/7213) and placebo (9/5493) arms. Although 95% CIs were wide, pooling of all-cause mortality found no difference between groups (RR 0.88, 95% CI 0.50-1.52), including when stratified by participants with (RR 1.24, 95% CI 0.40-3.83) and without (RR 0.77, 95% CI 0.40-1.48) cardiovascular disease.
CONCLUSIONS
We found no evidence that varenicline increases the rate of cardiovascular serious adverse events. Results were similar among those with and without cardiovascular disease. Given varenicline's efficacy as a smoking cessation drug and the long-term cardiovascular benefits of cessation, it should continue to be prescribed for smoking cessation.

Meta-Analysis Review
BACKGROUND
Use of smokeless tobacco (ST) can lead to tobacco dependence and long-term use can lead to health problems including periodontal disease, cancer, and cerebrovascular and cardiovascular disease.
OBJECTIVES
To assess the effects of behavioural and pharmacologic interventions for the treatment of ST use.
SEARCH METHODS
We searched the Cochrane Tobacco Addiction Group specialised register in June 2015.
SELECTION CRITERIA
Randomized trials of behavioural or pharmacological interventions to help users of ST to quit with follow-up of at least six months.
DATA COLLECTION AND ANALYSIS
We used standard methodological procedures as expected by the Cochrane Collaboration. We summarised outcomes as risk ratios (RRs). For subgroups of trials with similar types of intervention and without substantial statistical heterogeneity, we estimated pooled effects using a Mantel-Haenszel fixed-effect method.
MAIN RESULTS
We identified 34 trials that met the inclusion criteria, of which nine were new for this update, representing over 16,000 participants. There was moderate quality evidence from two studies suggesting that varenicline increases ST abstinence rates (risk ratio [RR] 1.34, 95% confidence interval (CI) 1.08 to 1.68, 507 participants). Pooled results from two trials of bupropion did not detect a benefit of treatment at six months or longer (RR 0.89, 95% CI 0.54 to 1.44, 293 participants) but the confidence interval was wide. Neither nicotine patch (five trials, RR 1.13, 95% CI 0.93 to 1.37, 1083 participants) nor nicotine gum (two trials, RR 0.99, 95% CI 0.68 to 1.43, 310 participants) increased abstinence. Pooling five studies of nicotine lozenges did increase tobacco abstinence (RR 1.36, 95% CI 1.17 to 1.59, 1529 participants) but confidence in this estimate is low as the result is sensitive to the exclusion of three trials which did not use a placebo control.Statistical heterogeneity was evident among the 17 trials of behavioural interventions: eight of them reported statistically and clinically significant benefits; six suggested benefit but with wide CIs and no statistical significance; and three had similar intervention and control quit rates and relatively narrow CIs. Heterogeneity was not explained by study design (individual or cluster randomization), whether participants were selected for interest in quitting, or specific intervention components. In a post hoc subgroup analysis, trials of behavioural interventions incorporating telephone support, with or without oral examination and feedback, were associated with larger effect sizes, but oral examination and feedback alone were not associated with benefit.In one trial an interactive website increased abstinence more than a static website. One trial comparing immediate cessation using nicotine patch versus a reduction approach using either nicotine lozenge or brand switching showed greater success for the abrupt cessation group.
AUTHORS' CONCLUSIONS
Varenicline, nicotine lozenges and behavioural interventions may help ST users to quit. Confidence in results for nicotine lozenges is limited. Confidence in the size of effect from behavioural interventions is limited because the components of behavioural interventions that contribute to their impact are not clear.

Meta-Analysis Review
BACKGROUND
Acetylcholinesterase inhibitors (AChEIs) and memantine are commonly used in the management of dementia. In routine clinical practice, dementia is often monitored via the Mini-Mental State Examination (MMSE). We conducted a systematic review and meta-analysis of the effects of these drugs on MMSE scores.
SUMMARY
Eighty trials were identified. Pooled effect estimates were in favour of both AChEIs and memantine at 6 months. Meta-regression indicated that dementia subtype was a moderator of AChEI treatment effect, with the effect of treatment versus control twice as high for patients with Parkinson disease dementia/ dementia with Lewy bodies (2.11 MMSE points at 6 months) as for patients with Alzheimer disease/vascular dementia (0.91 MMSE points at 6 months). Key Messages: AChEIs demonstrate a modest effect versus control on MMSE scores which is moderated by dementia subtype. For memantine the effect is smaller.

Meta-Analysis
IMPORTANCE
The association between the use of medications and the development of bullous pemphigoid (BP) is unclear.
OBJECTIVE
To assess the associations between previous exposure to certain medications and BP.
DATA SOURCES
For this systematic review and meta-analysis, PubMed, the Cochrane Central Register of Controlled Trials, and Embase were searched for relevant studies from inception to February 20, 2020.
STUDY SELECTION
Case-control or cohort studies and randomized clinical trials that examined the odds or risk of BP in patients with previous medication use were included. No geographic or language limitations were imposed.
DATA EXTRACTION AND SYNTHESIS
The Meta-analysis of Observational Studies in Epidemiology (MOOSE) guideline was followed. The Newcastle-Ottawa Scale was used to evaluate the risk of bias of included observational studies; Cochrane Collaboration's tool was used for randomized clinical trials. Aggregate data were used to conduct a random-effects model meta-analysis if the included studies were sufficiently homogenous. Subgroup analyses were performed for use of various medications of the same category.
MAIN OUTCOMES AND MEASURES
Odds ratio (OR), hazard ratio, and risk ratio of bullous pemphigoid in association with medication use.
RESULTS
This meta-analysis included 13 case-control studies, 1 cohort study, and 1 randomized clinical trial with a total of 285 884 participants. The meta-analysis of case-control studies showed a significant association of BP with previous use of aldosterone antagonists (pooled OR, 1.75; 95% CI, 1.28-2.40), dipeptidyl peptidase 4 inhibitors (pooled OR, 1.92; 95% CI, 1.55-2.38), anticholinergics (pooled OR, 3.12; 95% CI, 1.54-6.33), and dopaminergic medications (pooled OR, 2.03; 95% CI, 1.34-3.05). One cohort study found an increased risk of BP among patients receiving dipeptidyl peptidase 4 inhibitors (hazard ratio, 2.38; 95% CI, 1.16-4.88; P = .02). One trial found a higher occurrence of BP in patients with diabetes receiving linagliptin (0.2% in diabetes group vs 0% in the placebo group).
CONCLUSIONS AND RELEVANCE
The findings of this systematic review and meta-analysis suggest that aldosterone antagonists, dipeptidyl peptidase 4 inhibitors, anticholinergics, and dopaminergic medications are associated with BP. These medications should be judiciously prescribed, particularly in high-risk patients who are elderly and have disabling neurologic disorders.
