Meta-Analysis
BACKGROUND
Magnesium supplementation is often purported to improve sleep; however, as both an over-the-counter sleep aid and a complementary and alternative medicine, there is limited evidence to support this assertion. The aim was to assess the effectiveness and safety of magnesium supplementation for older adults with insomnia.
METHODS
A search was conducted in MEDLINE, EMBASE, Allied and Complementary Medicine, clinicaltrials.gov and two grey literature databases comparing magnesium supplementation to placebo or no treatment. Outcomes were sleep quality, quantity, and adverse events. Risk of bias and quality of evidence assessments were carried out using the RoB 2.0 and Grading of Recommendations Assessment, Development and Evaluation (GRADE) approaches. Data was pooled and treatment effects were quantified using mean differences. For remaining outcomes, a modified effects direction plot was used for data synthesis.
RESULTS
Three randomized control trials (RCT) were identified comparing oral magnesium to placebo in 151 older adults in three countries. Pooled analysis showed that post-intervention sleep onset latency time was 17.36 min less after magnesium supplementation compared to placebo (95% CI - 27.27 to - 7.44, p = 0.0006). Total sleep time improved by 16.06 min in the magnesium supplementation group but was statistically insignificant. All trials were at moderate-to-high risk of bias and outcomes were supported by low to very low quality of evidence.
CONCLUSION
This review confirms that the quality of literature is substandard for physicians to make well-informed recommendations on usage of oral magnesium for older adults with insomnia. However, given that oral magnesium is very cheap and widely available, RCT evidence may support oral magnesium supplements (less than 1 g quantities given up to three times a day) for insomnia symptoms.

Meta-Analysis Review
BACKGROUND & AIMS
This study aimed (1) to systematically review controlled trials of solid food diets for the treatment of inflammatory bowel disease (IBD); and (2) to grade the overall quality of evidence.
METHODS
Systematic review of prospective controlled trials of solid food diets for the induction or maintenance of remission in IBD. Two authors independently performed study selection, data extraction, and assessment of certainty of evidence. Meta-analyses were performed on studies with quantitative data on response, remission, and relapse.
RESULTS
There were 27 studies for meta-analysis. For induction of remission in Crohn's disease (CD), low refined carbohydrate diet and symptoms-guided diet outperformed controls, but studies had serious imprecision and very low certainty of evidence. The Mediterranean diet was similar to the Specific Carbohydrate Diet (low certainty of evidence), and partial enteral nutrition (PEN) was similar to exclusive enteral nutrition (very low certainty of evidence). PEN reduced risk of relapse (very low certainty of evidence), whereas reduction of red meat or refined carbohydrates did not (low certainty of evidence). For ulcerative colitis, diets were similar to controls (very low and low certainty of evidence).
CONCLUSIONS
Among the most robust dietary trials in IBD currently available, certainty of evidence remains very low or low. Nonetheless, emerging data suggest potential benefit with PEN for induction and maintenance of remission in CD. Reduction of red meat and refined carbohydrates might not reduce risk of CD relapse. As more dietary studies become available, the certainty of evidence could improve, thus allowing for more meaningful recommendations for patients.

BACKGROUND
Stress is a natural response of the body, induced by factors of a physical (hunger, thirst, and infection) and/or psychological (perceived threat, anxiety, or concern) nature. Chronic, long-term stress may cause problems with sleep, concentration, and memory, as well as affective disorders. The passionflower () is a perennial plant with documented therapeutic properties. The literature data suggest that the passionflower itself, as well as its preparations, helps reduce stress and can therefore be helpful in the treatment of insomnia, anxiety, and depression. The objective of this systematic review was to evaluate in terms of its neuropsychiatric effects.
METHODS
The scientific databases PubMed, ClinTrials.gov, and Embase were searched up to 22 October 2019. The search identified randomized clinical trials describing the effects of in neuropsychiatric disorders.
RESULTS
The systematic review included nine clinical trials. The duration of the studies included in the analysis varied widely, from one day up to 30 days. Study participants were no less than 18 years old. In each of the papers, the effects of passionflower were measured by using a number of different tests and scales. The majority of studies reported reduced anxiety levels following the administration of preparations, with the effect less evident in people with mild anxiety symptoms. No adverse effects, including memory loss or collapse of psychometric functions, were observed.
CONCLUSION
may be helpful in treating some symptoms in neuropsychiatric patients.

Meta-Analysis Review
BACKGROUND & AIMS
Patients with Crohn's disease (CD) treated with ustekinumab who experience inadequate response, or loss of response after standard induction and/or maintenance dosing may benefit from dose escalation. We conducted a systematic review and meta-analysis examining the effectiveness of reinduction and/or dose interval shortening of ustekinumab in patients with active CD despite standard induction and maintenance.
METHODS
Through a systematic literature search through March 31, 2021, we identified 15 cohort studies in 925 adults with CD with inadequate response or loss of response to standard dose ustekinumab, underwent dose escalation (reinduction and/or dose interval shortening to <8 weeks), and reported rates of achieving clinical response, corticosteroid-free clinical remission, endoscopic response, and/or remission. We calculated pooled rates (with 95% confidence intervals) using random effects meta-analysis and examined factors associated with response to dose escalation through qualitative synthesis of individual studies.
RESULTS
On meta-analysis, 55% of patients (95% confidence interval, 52%-58%) with inadequate response or loss of response who underwent ustekinumab dose escalation achieved clinical response, with moderate heterogeneity (I = 57%). Approximately 61% of patients were able to achieve endoscopic response, including 29% who achieved endoscopic remission. Dose interval shortening alone recaptured response in 57% patients. No consistent factors associated with response to dose escalation were identified on qualitative synthesis.
CONCLUSION
In real word settings, ustekinumab dose escalation was effective in achieving response in patients with CD with inadequate response, or loss of response to standard dose induction and/or maintenance therapy.

Beta-adrenoreceptor antagonist (beta-blocker) poisoning is a common overdose which can lead to significant morbidity and mortality. To evaluate the effects of treatments for beta-adrenoreceptor antagonist poisoning. Searches were conducted across MEDLINE (1946-26 November 2019, Ovid); Embase (1974-26 November 2019, Ovid); and the Cochrane Central Register of Controlled Trials (CENTRAL, to 26 November 2019) utilising a combination of subject headings and free text. The search strategy identified 15, 553 citations. Two reviewers screened titles and abstracts prior to selecting 141 articles (Kappa on articles included = 0.982, 95% CI 0.980-0.985). Primary outcomes included mortality and improvement in haemodynamic parameters (e.g., heart rate, blood pressure or a composite measure able to quantitate a haemodynamic response). The risk of bias was high for all interventions. Fifteen case reports described the administration of activated charcoal and five detailed the use of gastric lavage. As there was concurrent utilisation of multiple interventions, it was difficult to draw definitive conclusions regarding the relative contribution of these interventions to mortality or survival. The use of catecholamines in treating beta-blocker toxicity was reported in 16 case reports, 3 case series and 2 animal studies. These agents most likely provided a survival benefit and improved haemodynamics. Multiple intravenous boluses of atropine were associated with improvement in heart rate and blood pressure in one case report. Intravenous calcium was associated with an improvement in haemodynamics in three out of six case reports but in association with multiple other therapies as well as in two animal studies. The use of this therapy was associated with mortality benefit in 10 case series. Two case reports showed clear haemodynamic improvement in a timeframe consistent with insulin administration (bolus then continuous infusion). Maintenance dosing ranged from 1 to 10 units/kg/h of insulin. However, it is unclear whether high-dose insulin euglycaemic therapy improved haemodynamic response above catecholamines and other inotropic agents in humans. Hypoglycaemia and hypokalemia were commonly observed adverse effects. Glucagon was associated with minor improvements in haemodynamics through an increase in heart rate in two cases series, nine case reports and five animal studies. Four case reports reported an association with improvement in haemodynamics following administration of methylene blue but in the setting of co-ingestion with amlodipine. There was variable response to intravenous lipid emulsion therapy reported in 10 case series, 5 animal studies and 21 case reports. There were four case reports showing variable response to lignocaine in arrhythmias secondary to beta-blocker toxicity. Fructose diphosphate, levosimendan and amrinone did not provide a mortality or significant haemodynamic benefit in three animal studies and nine case reports. . Veno-arterial extracorporeal membrane oxygenation was associated with improved survival in patients with severe cardiogenic shock or cardiac arrest in an observational study and four cases series. The evidence of four case reports suggest haemodialysis may assist in the management of massive overdose of specific water-soluble beta-blockers (e.g., atenolol) by improving elimination; however, a survival or haemodynamic benefit was not established. One case series and a single case report showed the utility of temporary overdrive cardiac pacing to prevent arrhythmias in sotalol toxicity. Catecholamines, vasopressors, high-dose insulin euglycaemic therapy and veno-arterial extracorporeal membrane oxygenation were associated with reduced mortality. However, it must be acknowledged that multiple treatments were often given simultaneously. Haemodynamic improvements in blood pressure and cardiac output were seen with the use of catecholamines, vasopressin and high-dose insulin euglycaemic therapy. Evidence for treatment recommendations is almost entirely drawn from very low- to low-quality studies and subject to bias. However, it is reasonable to have a graduated response to cardiovascular instability beginning with intravenous fluids, commencement of a single or a combination of catecholamine inotropes and vasopressors depending upon the type of haemodynamic compromise (bradycardia, left ventricular dysfunction, vasodilation). High-dose insulin euglycaemic therapy can be introduced as an adjunctive inotrope and lastly, more invasive methods such as veno-arterial extracorporeal membrane oxygenation should be considered in cases unresponsive to other therapies.

PloS One 2021To determine the effect of Ashwagandha extract on sleep. (Meta-Analysis)
Meta-Analysis
OBJECTIVE
To determine the effect of Ashwagandha extract on sleep.
METHODS
A comprehensive search was conducted in CENTRAL, MEDLINE, SCOPUS, Google Scholars, World Health Organization Trials Portal, ClinicalTrials.gov, Clinical Trial Registry of India, and AYUSH Research Portal for all appropriate trials. Randomized controlled trials that examined the effect of Ashwagandha extract versus placebo on sleep in human participants 18 years old and above were considered. Two authors independently read all trials and independently extracted all relevant data. The primary outcomes were sleep quantity and sleep quality. The secondary outcomes were mental alertness on rising, anxiety level, and quality of life.
RESULTS
A total of five randomized controlled trials containing 400 participants were analyzed. Ashwagandha extract exhibited a small but significant effect on overall sleep (Standardized Mean Difference -0.59; 95% Confidence Interval -0.75 to -0.42; I2 = 62%). The effects on sleep were more prominent in the subgroup of adults diagnosed with insomnia, treatment dosage ≥600 mg/day, and treatment duration ≥8 weeks. Ashwagandha extract was also found to improve mental alertness on rising and anxiety level, but no significant effect on quality of life. No serious side effects were reported.
CONCLUSION
Ashwagandha extract appears to has a beneficial effect in improving sleep in adults. However, data on the serious adverse effects of Ashwagandha extract are limited, and more safety data would be needed to assess whether it would be safe for long-term use.

Meta-Analysis
Chronic obstructive pulmonary disease patient care must include confirming a diagnosis with postbronchodilator spirometry. Because of the clinical heterogeneity and the reality that airflow obstruction assessed by spirometry only partially reflects disease severity, a thorough clinical evaluation of the patient should include assessment of symptom burden and risk of exacerbations that permits the implementation of evidence-informed pharmacologic and nonpharmacologic interventions. This guideline provides recommendations from a comprehensive systematic review with a meta-analysis and expert-informed clinical remarks to optimize maintenance pharmacologic therapy for individuals with stable COPD, and a revised and practical treatment pathway based on new evidence since the 2019 update of the Canadian Thoracic Society (CTS) Guideline. The key clinical questions were developed using the Patients/Population (P), Intervention(s) (I), Comparison/Comparator (C), and Outcome (O) model for three questions that focuses on the outcomes of symptoms (dyspnea)/health status, acute exacerbations, and mortality. The evidence from this systematic review and meta-analysis leads to the recommendation that all symptomatic patients with spirometry-confirmed COPD should receive long-acting bronchodilator maintenance therapy. Those with moderate to severe dyspnea (modified Medical Research Council ≥ 2) and/or impaired health status (COPD Assessment Test ≥ 10) and a low risk of exacerbations should receive combination therapy with a long-acting muscarinic antagonist/long-acting ẞ2-agonist (LAMA/LABA). For those with a moderate/severe dyspnea and/or impaired health status and a high risk of exacerbations should be prescribed triple combination therapy (LAMA/LABA/inhaled corticosteroids) azithromycin, roflumilast or N-acetylcysteine is recommended for specific populations; a recommendation against the use of theophylline, maintenance systemic oral corticosteroids such as prednisone and inhaled corticosteroid monotherapy is made for all COPD patients.

Medicine Mar 2021This systematic review investigated the clinical effects of inhalation aromatherapy for the treatment of sleep problems such as insomnia. (Meta-Analysis)
Meta-Analysis
BACKGROUND
This systematic review investigated the clinical effects of inhalation aromatherapy for the treatment of sleep problems such as insomnia.
METHODS
Studies on sleep problems and inhalation aromatherapy, published in Korean and international journals, were included in the meta-analysis. Five domestic and international databases, respectively each, were used for the literature search. Keywords included sleep disorder, sleep problems, insomnia, and aroma inhalation, and the related literature was further searched. After the screening, selected articles were assessed for their quality and conducted the risk of bias using RevMan 5.0, a systematic literature review was then conducted. A meta-analysis comparing the averages was conducted on studies that reported numerical values. Additionally, meta-analysis of variance and meta-regression analyses were performed.
RESULTS
Meta-analysis of the 34 studies using the random-effects model revealed that the use of aromatherapy was highly effective in improving sleep problems such as insomnia, including quantitative and qualitative sleep effects (95% confidence interval [CI], effect sizes = 0.6491). Subgroup analysis revealed that the secondary outcomes including stress, depression, anxiety, and fatigue were significantly effective. The single aroma inhalation method was more effective than the mixed aroma inhalation method. Among the single inhalation methods, the lavender inhalation effect was the greatest.
CONCLUSION
Inhalation aromatherapy is effective in improving sleep problems such as insomnia. Therefore, it is essential to develop specific guidelines for the efficient inhalation of aromatherapy.
ETHICS AND DISSEMINATION
Ethical approval is not required because individual patient data are not included. The findings of this systematic review were disseminated through peer-reviewed publications or conference presentations.

Meta-Analysis
Apraxia affects 20% of the right brain-damaged patients and 50% of the left brain-damaged patients. This disorder of motor programming reduces patients' independence and there are few guidelines on the rehabilitative treatment in the physiotherapy and speech therapy field.The aim of this study was to assess which therapeutic interventions are the most effective in stroke patients with apraxia in considering the mentioned purviews. Four databases were systematically searched in order to detect all available studies investigating the physical and speech rehabilitation of patients. The literature research produced five studies including 168 patients for the physiotherapy and 50 for speech therapy fields; two were eligible for meta-analysis. Quality was rated with Jadad, PEDro scale and Cochrane Risk Of Bias Tool. Both for physiotherapy and speech therapy fields, the RCTs interventions obtained statistically significant results for outcomes of interest. Despite this, it is still not possible to determine the best approach due to the low number of patients involved, the lack of maintenance of the results at follow up and the timing of the revaluation period being very short to confirm the efficacy of treatments.

Review
BACKGROUND
Patients with kidney failure require vascular access to receive maintenance haemodialysis (HD), which can be achieved by an arteriovenous fistula or a central venous catheter (CVC). CVC use is related to frequent complications such as venous stenosis and infection. Venous stenosis occurs mainly due to trauma caused by the entrance of the catheter into the venous lumen and repeated contact with the vein wall. A biofilm, a colony of irreversible adherent and self-sufficient micro-organisms embedded in a self-produced matrix of exopolysaccharides, is associated with the development of infections in patients with indwelling catheters. Despite its clinical relevance, the treatment of catheter-related bloodstream infections (CRBSIs) in patients receiving maintenance HD remains controversial, especially regarding catheter management. Antibiotic lock solutions may sterilise the catheter, treat the infection and prevent unnecessary catheter procedures. However, such treatment may also lead to antibiotic resistance or even clinical worsening in certain more virulent pathogens. Catheter removal and delayed replacement may remove the source of infection, improving infectious outcomes, but this approach may also increase vascular access stenosis, thrombosis or both, or even central vein access failure. Catheter guidewire exchange attempts to remove the source of infection while maintaining access to the same vein and, therefore, may improve clinical outcomes and preserve central veins for future access.
OBJECTIVES
To assess the benefits and harms of different interventions for CRBSI treatment in patients receiving maintenance HD through a permanent CVC, such as systemic antibiotics alone or systemic antibiotics combined with either lock solutions or catheter guidewire exchange or catheter replacement.
SEARCH METHODS
We searched the Cochrane Kidney and Transplant Register of Studies up to 21 December 2021 through contact with the Information Specialist using search terms relevant to this review. Studies in the Register were identified through searches of CENTRAL, MEDLINE, and EMBASE, conference proceedings, the International Clinical Trials Register (ICTRP) Search Portal, and ClinicalTrials.gov.
SELECTION CRITERIA
We included all randomised controlled trials (RCTs) and quasi-RCTs evaluating the management of CRBSI in permanent CVCs in people receiving maintenance HD.
DATA COLLECTION AND ANALYSIS
Two authors independently selected studies for inclusion, assessed their risk of bias, and performed data extraction. Results were expressed as risk ratios (RR) or hazard ratios (HR) for dichotomous outcomes and mean difference (MD) for continuous outcomes, with their 95% confidence intervals (CI). The certainty of the evidence was assessed using GRADE.
MAIN RESULTS
We identified two RCTs and one quasi-RCT that enrolled 760 participants addressing the treatment of CRBSIs in people (children and adults) receiving maintenance HD through CVC. No two studies compared the same interventions. The quasi-RCT compared two different lock solutions (tissue plasminogen activator (TPA) and heparin) with concurrent systemic antibiotics. One RCT compared systemic antibiotics alone and in association with an ethanol lock solution, and the other compared systemic antibiotics with different catheter management strategies (guidewire exchange versus removal and replacement). The overall certainty of the evidence was downgraded due to the small number of participants, high risk of bias in many domains, especially randomisation, allocation, and other sources of bias, and missing outcome data. It is uncertain whether an ethanol lock solution used with concurrent systemic antibiotics improved CRBSI eradication compared to systemic antibiotics alone (RR 1.61, 95% CI 1.16 to 2.23) because the certainty of this evidence is very low. There were no reported differences between the effects of TPA and heparin lock solutions on cure rates (RR 0.92, 95% CI 0.74 to 1.15) or between catheter guidewire exchange versus catheter removal with delayed replacement, expressed as catheter infection-free survival (HR 0.88, 95% CI 0.43 to 1.79). To date, no results are available comparing other interventions. Outcomes such as venous stenosis and/or thrombosis, antibiotic resistance, death, and adverse events were not reported.
AUTHORS' CONCLUSIONS
Currently, there is no available high certainty evidence to support one treatment over another for CRBSIs. The benefit of using ethanol lock treatment in combination with systemic antibiotics compared to systemic antibiotics alone for CRBSIs in patients receiving maintenance HD remains uncertain due to the very low certainty of the evidence. Hence, further RCTs to identify the benefits and harms of CRBSI treatment options are needed. Future studies should unify CRBSI and cure definitions and improve methodological design.
