Meta-Analysis
A four-oil intravenous lipid emulsion improves markers of liver function, triglyceride levels and shortens length of hospital stay in adults: a systematic review and meta-analysis.
Clinical trials have reported that a four-oil intravenous lipid emulsion (SMOFlipid) play a positive role in immune function, but showed inconsistent outcomes compared to other lipid emulsions. A systematic review and meta-analysis was conducted to evaluate the effect of SMOFlipid on liver function, triglycerides (TG), inflammatory markers, and clinical outcomes in hospitalized adults after short-term use compared to others. A search of the PubMed, Medline, Embase, China National Knowledge Infrastructure, and Wanfang databases was performed to identify the included randomized controlled trials. Trials with adults who were administrated a short-term course of SMOFlipid were included. A meta-analysis on liver function markers, TG, inflammatory markers, and clinical outcomes was conducted. A total of 18 randomized controlled trials with 1188 patients were included. Compared to other lipid emulsions, SMOFlipid was associated with a significant reduction in ALT, AST, γ-glutamyltransferase, total bilirubin, TG, C-reactive protein and length of hospital stay. No effect on serum interleukin-6 levels or adverse events were observed. For adult patients, our meta-analysis indicated that SMOFlipid may be beneficial to the liver and prone to prevent hyperlipidemia. The SMOFlipid also shortened length of hospital stay.

Meta-Analysis
BACKGROUND
Eczema and food allergy are common health conditions that usually begin in early childhood and often occur together in the same people. They can be associated with an impaired skin barrier in early infancy. It is unclear whether trying to prevent or reverse an impaired skin barrier soon after birth is effective in preventing eczema or food allergy.
OBJECTIVES
Primary objective To assess effects of skin care interventions, such as emollients, for primary prevention of eczema and food allergy in infants Secondary objective To identify features of study populations such as age, hereditary risk, and adherence to interventions that are associated with the greatest treatment benefit or harm for both eczema and food allergy.
SEARCH METHODS
We searched the following databases up to July 2020: Cochrane Skin Specialised Register, CENTRAL, MEDLINE, and Embase. We searched two trials registers and checked reference lists of included studies and relevant systematic reviews for further references to relevant randomised controlled trials (RCTs). We contacted field experts to identify planned trials and to seek information about unpublished or incomplete trials.
SELECTION CRITERIA
RCTs of skin care interventions that could potentially enhance skin barrier function, reduce dryness, or reduce subclinical inflammation in healthy term (> 37 weeks) infants (0 to 12 months) without pre-existing diagnosis of eczema, food allergy, or other skin condition were included. Comparison was standard care in the locality or no treatment. Types of skin care interventions included moisturisers/emollients; bathing products; advice regarding reducing soap exposure and bathing frequency; and use of water softeners. No minimum follow-up was required.
DATA COLLECTION AND ANALYSIS
This is a prospective individual participant data (IPD) meta-analysis. We used standard Cochrane methodological procedures, and primary analyses used the IPD dataset. Primary outcomes were cumulative incidence of eczema and cumulative incidence of immunoglobulin (Ig)E-mediated food allergy by one to three years, both measured by the closest available time point to two years. Secondary outcomes included adverse events during the intervention period; eczema severity (clinician-assessed); parent report of eczema severity; time to onset of eczema; parent report of immediate food allergy; and allergic sensitisation to food or inhalant allergen.
MAIN RESULTS
This review identified 33 RCTs, comprising 25,827 participants. A total of 17 studies, randomising 5823 participants, reported information on one or more outcomes specified in this review. Eleven studies randomising 5217 participants, with 10 of these studies providing IPD, were included in one or more meta-analysis (range 2 to 9 studies per individual meta-analysis). Most studies were conducted at children's hospitals. All interventions were compared against no skin care intervention or local standard care. Of the 17 studies that reported our outcomes, 13 assessed emollients. Twenty-five studies, including all those contributing data to meta-analyses, randomised newborns up to age three weeks to receive a skin care intervention or standard infant skin care. Eight of the 11 studies contributing to meta-analyses recruited infants at high risk of developing eczema or food allergy, although definition of high risk varied between studies. Durations of intervention and follow-up ranged from 24 hours to two years. We assessed most of this review's evidence as low certainty or had some concerns of risk of bias. A rating of some concerns was most often due to lack of blinding of outcome assessors or significant missing data, which could have impacted outcome measurement but was judged unlikely to have done so. Evidence for the primary food allergy outcome was rated as high risk of bias due to inclusion of only one trial where findings varied when different assumptions were made about missing data. Skin care interventions during infancy probably do not change risk of eczema by one to two years of age (risk ratio (RR) 1.03, 95% confidence interval (CI) 0.81 to 1.31; moderate-certainty evidence; 3075 participants, 7 trials) nor time to onset of eczema (hazard ratio 0.86, 95% CI 0.65 to 1.14; moderate-certainty evidence; 3349 participants, 9 trials). It is unclear whether skin care interventions during infancy change risk of IgE-mediated food allergy by one to two years of age (RR 2.53, 95% CI 0.99 to 6.47; 996 participants, 1 trial) or allergic sensitisation to a food allergen at age one to two years (RR 0.86, 95% CI 0.28 to 2.69; 1055 participants, 2 trials) due to very low-certainty evidence for these outcomes. Skin care interventions during infancy may slightly increase risk of parent report of immediate reaction to a common food allergen at two years (RR 1.27, 95% CI 1.00 to 1.61; low-certainty evidence; 1171 participants, 1 trial). However, this was only seen for cow's milk, and may be unreliable due to significant over-reporting of cow's milk allergy in infants. Skin care interventions during infancy probably increase risk of skin infection over the intervention period (RR 1.34, 95% CI 1.02 to 1.77; moderate-certainty evidence; 2728 participants, 6 trials) and may increase risk of infant slippage over the intervention period (RR 1.42, 95% CI 0.67 to 2.99; low-certainty evidence; 2538 participants, 4 trials) or stinging/allergic reactions to moisturisers (RR 2.24, 95% 0.67 to 7.43; low-certainty evidence; 343 participants, 4 trials), although confidence intervals for slippages and stinging/allergic reactions are wide and include the possibility of no effect or reduced risk. Preplanned subgroup analyses show that effects of interventions were not influenced by age, duration of intervention, hereditary risk, FLG mutation, or classification of intervention type for risk of developing eczema. We could not evaluate these effects on risk of food allergy. Evidence was insufficient to show whether adherence to interventions influenced the relationship between skin care interventions and risk of developing eczema or food allergy.
AUTHORS' CONCLUSIONS
Skin care interventions such as emollients during the first year of life in healthy infants are probably not effective for preventing eczema, and probably increase risk of skin infection. Effects of skin care interventions on risk of food allergy are uncertain. Further work is needed to understand whether different approaches to infant skin care might promote or prevent eczema and to evaluate effects on food allergy based on robust outcome assessments.

Meta-Analysis
INTRODUCTION
Clinicians utilize lipid emulsion to treat local anesthetic toxicity and non-local anesthetic toxicities, a practice supported by animal experimentation and clinical experience. Prior meta-analysis confirmed a mortality benefit of lipid emulsion in animal models of local anesthetic toxicity but the benefit of lipid emulsion in models of non-local anesthetic toxicity remains unanswered. Further, swine suffer an anaphylactoid reaction from lipid emulsions calling into question their role as a model system to study lipid, so we examined swine and non-swine dependent outcomes in models of intravenous lipid emulsion.
METHODS
We conducted a systematic review and meta-analysis examining the use of lipid emulsion therapy in animal models of cardiac toxicity. We quantified mortality using a random-effects odds-ratio method. Secondary outcomes included survival in the following subgroups: local-anesthetic systemic toxicity, non-local anesthetic toxicity, swine-based models, and non-swine models (e.g., rat, rabbit and dog). We assessed for heterogeneity with Cochran's Q and I. We examined bias with Egger's test & funnel plot analysis.
RESULTS
Of 2784 references screened, 58 met criteria for inclusion. Treatment with lipid emulsion reduced chance of death in all models of toxicity with an odds ratio of death of 0.26 (95% CI 0.16-0.44, Z-5.21, < 0.00001, Cohen's- = 0.72, = 60). Secondary outcomes confirmed a reduced chance of death in models of local anesthetic toxicity (OR 0.16 {95% CI 0.1-0.33}) and non-local anesthetic toxicity (OR 0.43 {95% CI 0.22-0.83}). Heterogeneity (Cochran's Q 132 {df = 59, < 0.01}, = 0.55) arose primarily from animal-model and disappeared ( < = 0.12) when we analyzed swine and non-swine subgroups independently. Swine only benefited in models of local anesthetic toxicity (OR 0.28 {95% CI 0.11-0.7}, = 0.0033) whereas non-swine models experienced a homogeneous benefit across all toxins (OR 0.1 {95% CI 0.06-0.16}, < 0.00001). Egger's test identified risk of bias with outliers on funnel plot analysis.
DISCUSSION
Lipid emulsion therapy reduces mortality in animal models of toxicity. Heterogeneity arises from the animal-model used. Swine only benefit in models of local anesthetic toxicity, potentially due to lipid dose, experimental design or swine's anaphylactoid reaction to lipid. Outlier analysis reinforced the need for appropriate dosing of lipid emulsion along with airway management and chest compressions in the setting of cardiac arrest.

Immunotherapy to improve pregnancy outcome in women with abnormal natural killer cell levels/activity and recurrent miscarriage or implantation failure: A systematic review and meta-analysis.
There is a trend towards offering immunotherapy to women with unexplained reproductive failure based on abnormal Natural Killer (NK) cell levels. Previous systematic reviews evaluating immunotherapy usage have not focused on women with abnormal level of NK cells. To address the gap in literature, this systematic review aims to evaluate the efficacy of immunotherapy to improve pregnancy outcome in women with recurrent miscarriage (RM) or implantation failure (RIF) specifically selected based on abnormal levels and/or activity of NK cells. Six databases were searched for peer-reviewed studies following PRISMA guidelines. Risk of bias assessment was conducted using RoB2 for randomized controlled trials (RCT) and ROBINS-I for non-RCT. Of 1025 studies identified, seven studies on intravenous immunoglobulin (IVIG) (four), prednisolone (one), etanercept (one) and intralipid (one) were included. Meta-analysis of the non-RCT IVIG studies (557 participants; 312 intervention, 245 controls) showed livebirth in favour of intervention (RR 2.57; 95 % CI = 1.79-3.69; p < 0.05), however there were significant heterogeneity (I = 62 %) and moderate to severe risk of bias in these studies. Individual RCTs reported improved livebirth outcome in etanercept, intralipid and prednisolone and this was significant in the former two (p < 0.05). In conclusion, there may be some benefit of immunotherapy, but paucity of high quality evidence means that it is not possible to support the use of immunotherapy even when selected based on abnormal NK cell level/activity. Further research with application of scientifically validated immunological biomarkers in well-planned large scale RCTs will determine whether immunotherapy is beneficial in this subpopulation of women.

Influence of different intravenous lipid emulsions on fatty acid status and laboratory and clinical outcomes in adult patients receiving home parenteral nutrition: A systematic review.
BACKGROUND & AIMS
Patients who have chronic intestinal failure require home parenteral nutrition (HPN) support. Intravenous lipid emulsions (IVLEs) are a vital part of HPN. The conventional IVLE is based on pure soybean oil, which contains a high concentration of omega-6 fatty acids. Alternative IVLEs are commercially available. These contain various oil blends and have different fatty acid compositions from soybean oil that could provide benefit to patients on HPN. The aim of this systematic review is to assess the effects of different IVLEs in adult patients requiring HPN.
METHODS
A systematic literature search was conducted up to October 2019 using relevant search terms in the Medline, EMBASE and CINAHL databases. Only randomised controlled trials (RCTs) in adults on HPN that compared two or more IVLEs were included. Data were extracted and the Cochrane Collaboration's tool for assessing risk of bias was used.
RESULTS
Six articles were identified for inclusion in this systematic review. Studies differed according to sample size, duration and the IVLEs compared. Four studies found no increased risk of adverse effects related to the different IVLEs, whilst one study found a higher frequency of serious adverse events with soybean oil. One study found higher serum α-tocopherol with the blend of soybean oil, medium chain triglycerides, olive oil and fish oil. Inflammatory markers were not affected by different IVLEs in three studies. Differences in liver function tests were minimal, but one study found slight abnormalities in patients receiving soybean oil. IVLEs containing olive oil or fish oil modified the blood fatty acid profile. No studies reported essential fatty acid deficiency.
CONCLUSIONS
There may be benefits of using alternative IVLEs to soybean oil-based emulsions in adults requiring HPN, although there is currently insufficient evidence to determine superiority of one formulation over another. More and larger RCTs are required in this area.

OBJECTIVE
Intravenous lipid emulsions (ILE) were developed many decades ago to supply nutritional requirements to patients unable to obtain adequate enteral nutrition. The utility of ILE was extended to therapeutics, facilitating the delivery of drugs. More recently, the potential for ILE to act as an antidote for inversion of drug toxicity has been recognized. This review aims to summarize the literature on ILE therapy as an antidote. Suggested mechanisms of action, safety profile, and recommendations on the administration of ILE in cases of drug intoxication are highlighted.
MATERIALS AND METHODS
A complete literature survey was performed using the PubMed database search to collect available information regarding mechanisms of ILE action as an antidote, ILE administration for drug toxicity, and presentation of adverse events.
RESULTS
A total of 102 studies met the selection criteria for inclusion in the review. Mainly used for local anesthetics toxicity, ILE therapy has been expanded in clinical toxicology involving overdose treatment of drugs other than local anesthetics. Partitioning in a lipid phase of fat droplets is a mechanism named the lipid sink phenomenon that has primarily been described to explain this action of ILE and remains the most widely accepted. At the same time, recent research has also revealed several molecular mechanisms that may contribute to ILE efficacy.
CONCLUSIONS
ILE therapy comprises a recognized approach in clinical toxicology. Due to the lack of randomized clinical trials, recommendations on administration are based on animal studies and published cases. Thus, the constantly increased knowledge about ILE therapy supports the need for a detailed appraisal.

BACKGROUND
Pharmaceutical nanotechnology represents an efficient alternative for the delivery of pharmacologically active plant-derived compounds, considering their protective capacity, oral bioavailability and drug vectorization capacity. In this context, butters obtained from plant seeds have emerged as promising products for the development of pharmacologically active nanostructures. They possess a complex lipid composition, allowing the formation of different emulsion systems with solid cores, since this mixture of different triglycerides is solid at room temperature and body temperature. Therefore, the systematic mapping around the technological development of nanostructures produced from plant-derived butters is potentially valuable for researchers interested in novel alternative formulations for pharmacological therapy, with potential industrial, economic, health and societal impacts.
METHODS
Systematic review was carried out by the search of scientific papers and patents deposited in official databases concerning the development of nanostructured pharmaceutical products using plantderived butters as starting material. The publications obtained were subjected to sorting and analysis by applying the following inclusion/exclusion criteria.
RESULTS
The Solid Lipid Nanoparticle (SLN) was the type of nanostructure produced in all the analyzed scientific papers, due to the physicochemical characteristics of the lipid constituents of plantderived butters. In this sense, 54% of the articles have reported the use of Cocoa Butter for the production of nanostructures; 28% for Shea Butter; 6% for Cupuacu Butter, 6% for Murumuru Butter and 6% for Bacuri Butter.
DISCUSSION
In the technological prospection, only two patents exhibited SLN as an invention based on cocoa butter and on shea butter, respectively. The production methods employed have included: phase inversion temperature, microemulsion, hot high pressure homogenization, high shear homogenization and ultrasonication.
CONCLUSION
In light of this prospective review, the encouragement of novel studies in lipids-based nanotechnology is evident, considering the small number of findings so far, in order to stimulate new research involving plant-derived butters from easily cultivated fruits in tropical regions, then stimulating the pharmaceutical development of new therapeutic alternatives using biocompatible and sustainable raw materials.

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.

Meta-Analysis
Comparative efficacy and safety of Chinese herbal injections combined with transcatheter hepatic arterial chemoembolization in treatment of liver cancer: a bayesian network Meta-analysis.
OBJECTIVE
To address the optimal Chinese herbal injections (CHIs) against liver cancer, the present network Meta-analysis is designed to investigate the comparative efficacy and safety of different CHIs.
METHODS
Several electronic databases were searched up to June 1st, 2017. The quality assessment was conducted and network Meta-analysis was performed to compare the efficacy and safety of different CHIs plus transcatheter hepatic arterial chemoembolization (TACE). Primary outcomes were 1-year and 2-year survival rate, the secondary outcomes includes the clinical effective rate, performance status and the adverse reactions (ADRs). Data analysis was applied Stata 13.0 and WinBUGS 1.4 software.
RESULTS
A total of 105 randomized controlled trials (RCTs) were identified for inclusion in this analysis, with data for 7683 patients and 13 CHIs. The results suggested that Javanica oil emulsion, Huachansu injection plus TACE were more favorable for 1-year and 2-year survival rate than other CHIs. Kanglaite, Astragalus polysaccharide injection plus TACE showed superiority in the clinical effective rate and performance status over other CHIs. And Shenmai injection plus TACE was superior to reducing ADRs than other CHIs for patients with liver cancer.
CONCLUSION
Our findings indicated that receiving CHIs combined with TACE may have therapeutic benefits for patients with liver cancer in improving survival rate, clinical effective rate, the performance status and alleviating the ADRs.

Comparative Study
BACKGROUND
Microemulsions drug delivery systems (MDDS) have been known to increase the bioavailability of hydrophobic drugs. The main challenge of the MDDS is the development of an effective and safe system for drug carriage and delivery. Biosurfactants are preferred surface-active molecules because of their lower toxicity and safe characteristics when compared to synthetic surfactants. Glycolipid and lipopeptide are the most common biosurfactants that were tested for MDDS. The main goal of the present systematic review was to estimate the available evidence on the role of biosurfactant in the development of MDDS.
SEARCH STRATEGY
Literature searches involved the main scientific databases and were focused on the period from 2005 until 2017. The Search filter composed of two items: "Biosurfactant" and/or "Microemulsion."
INCLUSION CRITERIA
Twenty-four studies evaluating the use of biosurfactant in MDDS were eligible for inclusion. Among these 14 were related to the use of glycolipid biosurfactants in the MDDS formulations, while four reported using lipopeptide biosurfactants and six other related review articles.
RESULTS
According to the output study parameters, biosurfactants acted as active stabilizers, hydrophilic or hydrophobic linkers and safety carriers in MDDS, and among them glycolipid biosurfactants had the most application in MDDS formulations.
CONCLUSION
Synthetic surfactants could be replaced by biosurfactants as an effective bio-source for MDDS due to their excellent self-assembling and emulsifying activity properties.
