Review
Gastroparesis is a gastric motility disorder characterized by delayed gastric emptying. It is a rare disease and difficult to treat effectively; management is a dilemma for gastroenterologists and surgeons alike. We conducted a systematic review of the literature to evaluate current diagnostic tools as well as treatment options. We describe key elements in the pathophysiology of the disease, in addition to current evidence on treatment alternatives, including nutritional considerations, medical and surgical options, and related outcomes.

Meta-Analysis
INTRODUCTION
The diagnosis of pancreatic exocrine insufficiency (PEI) is challenging. The C mixed triglyceride breath test (C MTGT) has emerged as a promising diagnostic method. However, there is need to assimilate high quality evidence to understand its accuracy and address variation in the conduct of the test. This systematic review aims to appraise the existing literature on the methodology and accuracy of the C MTGT.
METHODS
A systematic literature search of PUBMED, MEDLINE, and EMBASE databases identified articles describing the use of the C MTGT in the analysis of pancreatic function in adults. Data extraction addressed each methodological step in detail. These were combined in a narrative synthesis. For quantitative analysis, those studies within this search that assessed the accuracy of the C MTGT were selected.
RESULTS
37 studies were included for qualitative review, 6 assessed sensitivity and specificity of the C MTGT against another measure of PEI and were included in quantitative synthesis. Areas with a majority consensus were pre-test overnight fasting, a test meal with a lipid load of at least 10 g, within-test control of exercise and dietary intake, breath sampling every 30 min and the preference of isotope ratio mass spectrometry (IRMS) for analysis. Good evidence suggests there is no benefit to extend the total timeframe of breath sampling beyond 6 h. Areas of uncertainty are a) Duration of PERT cessation b) the addition of metoclopramide, c) the ideal test meal and d) if the time frame can be shortened. Quantitative analysis among 6 studies demonstrated a pooled sensitivity and specificity of the C MTGT for diagnosing PEI of 0.84 (95% CI: 0.73-0.91) and 0.87 (95% CI: 0.79-0.93) respectively.
CONCLUSION
There is yet to emerge a clear standard of breath test methodology that is validated for all causes of PEI and suitable for routine use. The accuracy of the C MTGT for diagnosing PEI is encouraging when compared to other measures. We present a suggested set protocol based on the current literature and identify areas that need further, high quality evidence. With refinement, the C MTGT could become a valuable, non-invasive PEI diagnostic tool that could be used outside of specialist centres.

Meta-Analysis
BACKGROUND
Dopamine antagonists are the main pharmacological options to treat gastroparesis. The aim of this study was to conduct a systematic literature review (SLR) to evaluate the profile of adverse events (AEs) of dopamine antagonists used in the treatment of children and adults with gastroparesis.
METHODS
We searched EMBASE and MEDLINE up to March 25, 2021, for relevant clinical trials and observational studies. We conducted a proportional meta-analysis to estimate the pooled occurrence of AEs (%), with 95% confidence interval (CI), from arm-level data across studies and the comparative occurrence of AEs from placebo-controlled clinical trials (odds ratio [OR] with 95% CI).
RESULTS
We identified 28 studies assessing AEs experienced by patients treated for gastroparesis with domperidone and metoclopramide; 22 studies contributed data to the meta-analyses. Cardiovascular, neurological, and endocrine AEs were commonly observed, with point incidences varying from 1 to > 50%. Clinically important AEs, such as QTc prolongation, occurred in 5% of patients treated with domperidone (95% CI: 3.32-8.62). Restlessness, an extrapyramidal AE, occurred in 15% of patients (95% CI: 7.48-26.61) treated with metoclopramide, with a 7-fold increase compared with patients receiving placebo (OR: 7.72; 95% CI: 1.27-47.05). Variation in terminology to describe extrapyramidal events precluded further pooled analyses. Additional meta-analyses were not feasible due to discrepancies in the assessment and reporting of the AEs.
CONCLUSIONS
The evidence confirms concerns of cardiovascular, extrapyramidal, and endocrine AEs in patients with gastroparesis treated with domperidone and metoclopramide. Imprecise AE reporting limits firm interpretation and conclusions.

Review
BACKGROUND
Upper endoscopy is the definitive treatment for upper gastrointestinal haemorrhage (UGIH). However, up to 13% of people who undergo upper endoscopy will have incomplete visualisation of the gastric mucosa at presentation. Erythromycin acts as a motilin receptor agonist in the upper gastrointestinal (GI) tract and increases gastric emptying, which may lead to better quality of visualisation and improved treatment effectiveness. However, there is uncertainty about the benefits and harms of erythromycin in UGIH.
OBJECTIVES
To evaluate the benefits and harms of erythromycin before endoscopy in adults with acute upper gastrointestinal haemorrhage, compared with any other treatment or no treatment/placebo.
SEARCH METHODS
We used standard, extensive Cochrane search methods. The latest search date was 15 October 2021.
SELECTION CRITERIA
We included randomised controlled trials (RCTs) that investigated erythromycin before endoscopy compared to any other treatment or no treatment/placebo before endoscopy in adults with acute UGIH.
DATA COLLECTION AND ANALYSIS
We used standard Cochrane methods. Our primary outcomes were 1. UGIH-related mortality and 2. serious adverse events. Our secondary outcomes were 1. all-cause mortality, 2. visualisation of gastric mucosa, 3. non-serious adverse events, 4. rebleeding, 5. blood transfusion, and 5. rescue invasive intervention. We used GRADE criteria to assess the certainty of the evidence for each outcome. MAIN RESULTS: We included 11 RCTs with 878 participants. The mean age ranged from 53.13 years to 64.5 years, and most participants were men (72.3%). One RCT included only non-variceal haemorrhage, one included only variceal haemorrhage, and eight included both aetiologies. We defined short-term outcomes as those occurring within one week of initial endoscopy. Erythromycin versus placebo Three RCTs (255 participants) compared erythromycin with placebo. There were no UGIH-related deaths. The evidence is very uncertain about the short-term effects of erythromycin compared with placebo on serious adverse events (risk difference (RD) -0.01, 95% confidence interval (CI) -0.04 to 0.02; 3 studies, 255 participants; very low certainty), all-cause mortality (RD 0.00, 95% CI -0.03 to 0.03; 3 studies, 255 participants; very low certainty), non-serious adverse events (RD 0.01, 95% CI -0.03 to 0.05; 3 studies, 255 participants; very low certainty), and rebleeding (risk ratio (RR) 0.63, 95% CI 0.13 to 2.90; 2 studies, 195 participants; very low certainty). Erythromycin may improve gastric mucosa visualisation (mean difference (MD) 3.63 points on 16-point ordinal scale, 95% CI 2.20 to 5.05; higher MD means better visualisation; 2 studies, 195 participants; low certainty). Erythromycin may also result in a slight reduction in blood transfusion (MD -0.44 standard units of blood, 95% CI -0.86 to -0.01; 3 studies, 255 participants; low certainty). Erythromycin plus nasogastric tube lavage versus no intervention/placebo plus nasogastric tube lavage Six RCTs (408 participants) compared erythromycin plus nasogastric tube lavage with no intervention/placebo plus nasogastric tube lavage. There were no UGIH-related deaths and no serious adverse events. The evidence is very uncertain about the short-term effects of erythromycin plus nasogastric tube lavage compared with no intervention/placebo plus nasogastric tube lavage on all-cause mortality (RD -0.02, 95% CI -0.08 to 0.03; 3 studies, 238 participants; very low certainty), visualisation of the gastric mucosa (standardised mean difference (SMD) 0.48 points on 10-point ordinal scale, 95% CI 0.10 to 0.85; higher SMD means better visualisation; 3 studies, 170 participants; very low certainty), non-serious adverse events (RD 0.00, 95% CI -0.05 to 0.05; 6 studies, 408 participants; very low certainty), rebleeding (RR 1.13, 95% CI 0.63 to 2.02; 1 study, 169 participants; very low certainty), and blood transfusion (MD -1.85 standard units of blood, 95% CI -4.34 to 0.64; 3 studies, 180 participants; very low certainty). Erythromycin versus nasogastric tube lavage Four RCTs (287 participants) compared erythromycin with nasogastric tube lavage. There were no UGIH-related deaths and no serious adverse events. The evidence is very uncertain about the short-term effects of erythromycin compared with nasogastric tube lavage on all-cause mortality (RD 0.02, 95% CI -0.05 to 0.08; 3 studies, 213 participants; very low certainty), visualisation of the gastric mucosa (RR 1.19, 95% CI 0.79 to 1.79; 2 studies, 198 participants; very low certainty), non-serious adverse events (RD -0.10, 95% CI -0.34 to 0.13; 3 studies, 213 participants; very low certainty), rebleeding (RR 0.77, 95% CI 0.40 to 1.49; 1 study, 169 participants; very low certainty), and blood transfusion (median 2 standard units of blood, interquartile range 0 to 4 in both groups; 1 study, 169 participants; very low certainty). Erythromycin plus nasogastric tube lavage versus metoclopramide plus nasogastric tube lavage One RCT (30 participants) compared erythromycin plus nasogastric tube lavage with metoclopramide plus nasogastric tube lavage. The evidence is very uncertain about the effects of erythromycin plus nasogastric tube lavage on all the reported outcomes (serious adverse events, visualisation of gastric mucosa, non-serious adverse events, and blood transfusion).
AUTHORS' CONCLUSIONS
We are unsure if erythromycin before endoscopy in people with UGIH has any clinical benefits or harms. However, erythromycin compared with placebo may improve gastric mucosa visualisation and result in a slight reduction in blood transfusion.

Review
BACKGROUND
Patients with cerebral palsy, a group of movement disorders with motor, and possibly communication and behavioral features that mimic catatonic signs, may benefit from efforts to improve the detection and treatment of comorbid catatonia. Given that cerebral palsy frequently co-occurs with conditions associated with catatonia, such as autism spectrum disorder, epilepsy, intellectual disability, and mood and psychotic disorders, lifetime prevalence of catatonia in this population may be high.
OBJECTIVE
This study aimed to systematically review the literature on catatonia and the related condition of neuroleptic malignant syndrome (NMS) in patients with cerebral palsy while presenting 2 additional cases of catatonia.
METHODS
We used the terms "cerebral palsy" in combination with "catatoni∗," related terms for catatonia, and "neuroleptic malignant syndrome" to query Ovid MEDLINE (1948 to November 28, 2022), PsycINFO, Cumulative Index to Nursing, and Allied Health Literature, and Embase for applicable case reports. The Neuroleptic Malignant Syndrome Information Service database was also manually searched.
RESULTS
In addition to our 2 catatonia reports, we identified 10 reports of catatonia in patients with cerebral palsy, as well as 8 reports of NMS. Patients with both conditions responded well, and sometimes rapidly, to treatment. Notably, of the 5 patients with catatonia and cerebral palsy who received electroconvulsive therapy, 2 developed recurrent self-limited hyperthermia posttreatment. We also identified several cases of baclofen withdrawal, which can be life threatening because of seizure risk, presenting with NMS-like features in patients with cerebral palsy who had malfunctioning intrathecal baclofen pumps for spasticity management.
CONCLUSIONS
Given frequent comorbidity of conditions associated with catatonia in patients with cerebral palsy, as well as routine treatment with medications that can induce NMS, such as metoclopramide and anticholinergics, catatonia and NMS may be underreported in the cerebral palsy patient population, despite being highly treatable. Possible underdiagnosis of catatonia in patients with cerebral palsy may be because of misattribution of overlapping features between the 2 conditions to cerebral palsy. Clinicians should be aware of possible recurrent self-limited fever when using electroconvulsive therapy to treat patients with catatonia and cerebral palsy while also being vigilant for intrathecal baclofen withdrawal when encountering NMS-like features in patients with cerebral palsy.

Meta-Analysis
BACKGROUND & AIMS
Although there have been multiple drugs tested in gastroparesis, their relative efficacy and safety are unknown. We evaluated this in a network meta-analysis of randomized controlled trials (RCTs).
METHODS
We searched the literature to September 7, 2022. We judged the efficacy of drugs based on global symptoms of gastroparesis; individual symptoms, including nausea, vomiting, abdominal pain, bloating, or fullness; and safety according to total adverse events and adverse events leading to withdrawal. We extracted data as intention-to-treat analyses, assuming dropouts to be treatment failures and reporting pooled relative risks (RRs) of not improving with 95% confidence intervals (CIs), ranking drugs according to P-score.
RESULTS
We identified 29 RCTs (3772 patients). Based on global symptoms, clebopride ranked first for efficacy (RR, 0.30; 95% CI, 0.16-0.57; P-score = .99) followed by domperidone (RR, 0.68; 95% CI, 0.48-0.98; P-score = .76). No other drug was superior to placebo. Only 2 drug classes were efficacious: in rank order, oral dopamine antagonists (RR, 0.58; 95% CI, 0.44-0.77; P-score = .96) and tachykinin-1 antagonists (RR, 0.69; 95% CI, 0.52-0.93; P-score = .83). For individual symptoms, oral metoclopramide ranked first for nausea (RR 0.46; 95% CI, 0.21-1.00; P-score = .95), fullness (RR 0.67; 95% CI, 0.35-1.28; P-score = .86), and bloating (RR 0.53; 95% CI, 0.30-0.93; P-score = .97), based on only 1 small trial. Only prucalopride was more likely to be associated with adverse events than placebo.
CONCLUSIONS
In a network meta-analysis, oral dopamine antagonists and tachykinin-1 antagonists were more efficacious than placebo for gastroparesis, but confidence in the evidence was low to moderate for most comparisons. There is an unmet need for efficacious therapies for gastroparesis.

Meta-Analysis Review
BACKGROUND & AIMS
Multiple drugs have been used to treat gastroparesis symptoms, yet their therapeutic benefits are poorly understood partly due to lack of insight into response and adverse event rates with placebo in randomized controlled trials (RCTs). We evaluated these issues systematically in drug trials for gastroparesis.
METHODS
We searched the medical literature through August 2, 2022 to identify RCTs comparing active drug with placebo in patients with gastroparesis. We assessed placebo response rates according to at least one of the following endpoints: improvement according to a composite outcome, nausea, vomiting, abdominal pain, bloating, or fullness, as well as total adverse events, and adverse events leading to withdrawal. We extracted data as intention-to-treat analyses with dropouts assumed to be treatment failures. We pooled placebo response and adverse event rates using a random effects model and expressed as proportions with 95% confidence intervals (CIs).
RESULTS
Thirty-five studies were eligible. Among 23 trials reporting a composite endpoint of improvement, the pooled placebo response rate was 29.3% (95% CI, 23.7%-35.2%). Pooled placebo response rates were higher in idiopathic compared with diabetic gastroparesis (34.2% vs 28.1%), among trials that did not use validated symptom questionnaires (31.2% vs 27.4%), and in RCTs of shorter duration (<4 weeks, 32.6% vs ≥9 weeks, 23.2%). Adverse events occurred in 33.8% (95% CI, 26.4%-41.8%) of patients with placebo, in 27 trials, and were less common in idiopathic compared with diabetic gastroparesis (17.9% vs 43.4%), trials of shorter duration (<4 weeks, 33.7% vs ≥9 weeks, 40.7%), and trials with lower randomization ratios of active drug to placebo (1:1, 26.7% vs 3:1, 50.5%).
CONCLUSIONS
This meta-analysis assessed placebo response and adverse event rates in gastroparesis. To accurately assess therapeutic gain, future trials should be a minimum of 8 weeks duration, use validated questionnaires, and distinguish gastroparesis subtypes.

BACKGROUND
Metoclopramide may be used to treat people suffering from acute migraine. However, no comprehensive investigation on this issue has been recorded. This review will provide more solid evidence for the use of metoclopramide in treating acute migraine.
AIM
To compare the efficacy of intravenous metoclopramide with other therapies in migraine attack treatment in an emergency department (ED).
METHODS
We included randomized controlled trials of participants older than 18 years with acute migraine headaches, which included at least one arm that received intravenous (IV) metoclopramide at the ED. A literature search of PubMed, Web of Science, Cochrane Collaboration, and Reference Citation Analysis on December 31, 2021 retrieved other drugs or placebo-controlled studies without language limitation. The risk of bias was assessed using the Cochrane risk of bias tool. The primary endpoint was pain reduction at 60 min or closest to 1 h after treatment, as measured by the pain scale. Secondary endpoints included adverse effects or reactions resulting from metoclopramide or comparisons.
RESULTS
Fourteen trials with a total of 1661 individuals were eligible for review. The risk of bias ranged from low to intermediate. IV metoclopramide administration was not associated with higher pain reduction at 1 h (Standard mean difference [SMD] = -0.03, 95% confidence interval [CI]: -0.33-0.28, = 0.87). However, metoclopramide was associated with better pain reduction than placebo (SMD = 1.04, 95%CI: 0.50-1.58, = 0.0002). In addition, side effects were not significantly different between IV metoclopramide and other drugs or placebo (odds ratio [OR] = 0.76, 95%CI: 0.48-1.19, = 0.09 and OR = 0.92, 95%CI: 0.31-2.74, = 0.54, respectively).
CONCLUSION
Metoclopramide is more effective than placebo in treating migraine in the ED. Despite the observed tendency of decreased side effects, its effectiveness compared to other regimens is poorly understood. More research on this area is needed to treat migraine in acute care settings effectively.

Review
Gastroparesis is a functional gastrointestinal disorder that more commonly affects women, with most cases being diagnosed during childbearing age. However, there is a paucity of data and guidelines to specifically highlight the epidemiology, disease course, maternal and fetal impact, and the management of existing gastroparesis during pregnancy. Apart from metoclopramide, there is no approved therapy specifically indicated for gastroparesis. More importantly, pregnant and breastfeeding women are excluded from clinical trials evaluating pharmacologic agents in the management of gastroparesis. This poses a real challenge to healthcare providers in counseling and managing patients with gastroparesis. In this systematic review, we summarize the current available literature and the knowledge gaps in the impact of pregnancy on gastroparesis and vice versa. We also highlight the efficacy and safety profiles of available pharmacologic and nonpharmacologic therapies in the management of patients with gastroparesis, with emphasis on judicious use of dietary approaches that are deemed relatively safe during pregnancy.

Meta-Analysis Review
TRANSESOPHAGEAL ECHOCARDIOGRAPHY (TEE) is carried out in various clinical settings, with an increasing importance, and sedation usually is required to perform it. Several sedative agents are available, and the authors aimed to compare the cardiovascular and respiratory safety of the strategies used for sedation in TEE through a systematic review with network meta-analysis (NMA). The MEDLINE, CENTRAL, EMBASE, and PsycInfo databases were searched in December 2020 for randomized clinical trials (RCTs) comparing sedation strategies for patients undergoing TEE. The authors assessed variations in systolic blood pressure (SBP), heart rate (HR), and peripheral oxygen saturation (SpO), along with the incidences of hypotension, bradycardia, and desaturation. A random-effect meta-analysis was performed. Nine RCTs (N = 881 patients) with 20 active arms (5 dexmedetomidine; 4 propofol; 4 midazolam; 3 midazolam + opioid; 2 ketamine + propofol; 1 midazolam + ondansetron; 1 midazolam + metoclopramide) and 1 placebo arm were included. Dexmedetomidine was associated with decreases in SBP (mean difference [MD] = -18.78 mmHg; 95% CI [-26.27 to -11.28]) and HR (MD = -11.15 beats/min; 95% CI [-16.15 to -6.15]). Dexmedetomidine significantly reduced the HR compared with ketamine + propofol (-16.90 beats/min; 95% CI: -33.21 to -0.58]) and midazolam + opioid (-24.15 beats/min; 95% CI: -42.67 to -5.63). Midazolam was found to reduce SBP (-12.09 mmHg; 95% CI: -20.43 to -3.74) and was shown to reduce SpO compared with the placebo (-1.00%; 95% CI -1.74 to -0.26). Based on the NMA, the drugs with a higher likelihood of decreasing both SBP and HR were dexmedetomidine and midazolam. All of the drugs led to a small decrease (only statistically significant for midazolam) in SpO, with the systematic use of supplemental O in some trials. The risks of hypotension, bradycardia, or desaturation were not significantly different among the evaluated drugs.
