Safety and Efficacy of Evacetrapib in Patients with Inadequately-controlled Hypercholesterolemia and High Cardiovascular Risk; A meta-analysis of Randomized Placebo-controlled Trials.
BACKGROUND
Low-density lipoprotein cholesterol (LDL-C) is causally related to cardiovascular disease. Inhibition of cholesteryl ester transfer protein with Evacetrapib may provide an additional treatment option for patients who do not reach their LDL-C goal with statins or patients who cannot tolerate statins. We aimed to evaluate the safety and efficacy of Evacetrapib in patients with inadequately-controlled hypercholesterolemia and high cardiovascular risk.
METHOD
A computer literature search for PubMed, Scopus, and Science Direct was carried out from inception to 2019 and was updated from January 2019 till March 2021. We included only RCTs. Data were pooled as a mean difference in a random-effect model using the Mantel-Haenzel (M-H) method. We used Open Meta [Analyst] software (by the center of evidence-based medicine, Oxford University, UK).
RESULTS
Five studies (n = 12,937 patients) reported in five articles were included in this meta-analysis. The overall pooled estimate showed that LDL-C was significantly lower in the evacetrapib group than the placebo group (MD -34.07 mg/dL, 95% CI [-40.66, -27.49], p<0.0001). The pooled estimate showed that Apo-B was significantly lower in the evacetrapib130 mg group than the placebo group (MD -22.64 mg/dL, 95% CI [-30.70, -14.58], p<0.0001). HDL-C was significantly higher in the evacetrapib group over the placebo group (MD 93.31 mg/dL, 95% CI [56.07, 130.56], p<0.0001).
CONCLUSION
Current evidence from five RCTs (12,539 participants) suggests that evacetrapib has favorable outcomes in patients with inadequately-controlled Hypercholesterolemia and high cardiovascular risks. Evacetrapib could significantly increase the HDL and Apo-A1 levels and lower the LDL cholesterol and Apo-B levels with an acceptable safety profile.

Alzheimer's disease (AD) is a complex and heterogeneous neurodegenerative disease. A wide range of techniques have been proposed to facilitate early diagnosis of AD, including biomarkers from the cerebrospinal fluid and blood. Although phosphorylated tau and amyloid beta are amongst the most promising biomarkers of AD, other peripheral biomarkers have been identified and in this review we synthesize the current knowledge on circulating fatty acids. Fatty acids are involved in different biological process including neurotransmission and inflammation. Interestingly, some fatty acids appear to be modulated during disease progression, including long chain saturated fatty acids, and polyunsaturated fatty acids, such as docosahexaenoic acid . However, discrepant results have been reported in the literature and there is the need for further validation and method standardization. Nonetheless, our literature review suggests that fatty acid analyses could potentially provide a valuable source of data to further inform the pathology and progression of AD.

INTRODUCTION
The Mediterranean Diet (MedDiet) is described as a plant-based dietary pattern with adherence associated with reductions in chronic disease risk and longevity. Although the nutrient profile is diverse and complex, the MedDiet is often described as a rich source of n-3 polyunsaturated fatty acids (PUFA) derived from fish, seafood and nuts. However, whether MedDiet adherence results in appreciable increases in tissue levels of n-3 PUFAs is yet to be systematically investigated. This systematic review synthesized the literature to determine the impact of the MedDiet on n-3 PUFA tissue levels.
MATERIALS AND METHODS
Medline, Embase, Amed, and CINAHL databases were searched for studies reporting on adherence to a MedDiet and tissue levels of n-3 PUFAs. PROSPERO registration number is CRD 42020162114.
RESULTS
Twenty-two studies were included. Seven were observational studies and 15 were randomised controlled trials (RCTs). All observational studies reported a positive relationship between adherence and higher tissue n-3 PUFA levels. Two-thirds (10/15) of RCTs reported significant increases in n-3 PUFA concentrations.
DISCUSSION
MedDiet adherence is associated with higher tissue levels of n-3 PUFA. However, we report heterogeneity in the description across all MedDiet interventions.

Levosimendan Can Improve the Level of B-Type Natriuretic Peptide and the Left Ventricular Ejection Fraction of Patients with Advanced Heart Failure: A Meta-analysis of Randomized Controlled Trials.
BACKGROUND AND AIMS
Levosimendan, a calcium (Ca)-sensitizing cardiotonic agent, is mainly used in patients with advanced heart failure. However, no research could explain how levosimendan reduces the mortality in advanced heart failure patients. We aim to illustrate the efficacy of levosimendan through clinical indexes.
METHODS
We searched PubMed, Embase, and CENTRAL from 1994 to August 2019 to compare the efficacy of levosimendan infusion for the treatment of advanced heart failure with that of other agents (placebo, dobutamine, furosemide, and prostaglandin E1). Levels of B-type natriuretic peptide (BNP) and N-terminal pro BNP (NT-proBNP), and left ventricular ejection fraction (LVEF) and heart rate (HR) were analyzed. The count data were analyzed by the standardized mean difference (SMD) and its 95% confidence interval (CI) to determine the effect size. We chose the random effect model or the fixed effect model according to the heterogeneity.
RESULTS
Nine randomized controlled trials with 413 patients were ultimately enrolled. Compared with other agents (placebo, dobutamine, furosemide, and prostaglandin E1), levosimendan significantly reduced the BNP level (SMD - 0.91; 95% CI - 1.44 to - 0.39; p = 0.001; I = 74.3%) and improved the LVEF (SMD 0.74; 95% CI 0.22-1.25; p = 0.005; I = 79.7%). However, levosimendan did not significantly change the HR (SMD 0.09; 95% CI - 0.24 to 0.42; p = 0.592; I = 51.5%). Meanwhile, we found that the main source of heterogeneity was the use of loaded or unloaded levosimendan.
CONCLUSION
Our meta-analysis suggests that intravenous levosimendan can reduce BNP level and increase LVEF in patients with advanced heart failure to reduce the mortality at the shortest follow-up available.

BACKGROUND
Previous studies have experimentally validated and reported that chemical constituents of marine sponges are a source of natural anti-inflammatory substances with the biotechnological potential to develop novel drugs.
AIMS
Therefore, the aim of this study was to perform a systematic review to provide an overview of the anti-inflammatory substances isolated from marine sponges with therapeutic potential.
METHODS
This systematic review was performed on the Embase, PubMed, Scopus and Web of Science electronic databases. In total, 613 were found, but 340 duplicate studies were excluded, only 100 manuscripts were eligible, and 83 were included.
RESULTS
The results were based on and assays, and the anti-inflammatory effects of 251 bioactive compounds extracted from marine sponges were investigated. Their anti-inflammatory activities include inhibition of pro-inflammatory mediators, such as tumor necrosis factor- α (TNF-α), interleukin-6 (IL-6), nitrite or nitric oxide (NO), inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), interleukin 1β (IL-1β), prostaglandin E2 (PGE2), phospholipase A2 (PLA2), nuclear transcription factor-kappa B (NF-κB), leukotriene B4 (LTB4), cyclooxygenase- 1 (COX-1), and superoxide radicals.
CONCLUSION
In conclusion, data suggest (approximately 98% of articles) that substances obtained from marine sponges may be promising for the development of novel anti-inflammatory drugs for the treatment of different pathological conditions.

Bipolar disorder (BD) is a mood psychiatric disorder described by changes between depressive, hypomanic, or manic episodes. The aimed of the present study was evaluated possible changes in the AA pathway in BD through a systematic review of observational studies. A search in the electronic databases was proceeded, on Cochrane Library, MEDLINE, EMBASE, PsycINFO, Google Scholar and the British Library for studies published until August 2020. A search strategy was developed using the terms: "Bipolar Disorder" and "Phospholipase A2" or "Arachidonic Acids" or "Cyclooxygenase 2" or "Prostaglandins E" as text words and Medical Subject Headings (i.e., MeSH and EMTREE). Seven primary studies were included in the systematic review, with a total of 246 BD patients, 20 depression patients, and 425 heathy controls (HC). The studies showed contradictory results in the AA and PLA2, no primary articles with COX and PGE2 assessments were included in this review. According to the Newcastle-Ottawa quality score scale (NOS), our systematic review presented high quality. The investigation of the inflammatory pathway of AA still needs further investigation and evidence, given the growing number of studies suggesting the efficacy of anti-inflammatory drugs as adjunctive therapy in the pharmacological treatment of BD.

Meta-Analysis
A number of studies have examined the beneficial effects of cocoa consumption on markers of oxidative stress in different population, however, the findings have been inconclusive. Herein, we systematically reviewed available interventional studies to elucidate the overall impact of cocoa consumption on markers of oxidative stress among adult population. PubMed, Cochrane's library, Science Direct, Scopus, Google scholar and ISI web of science databases were searched for all available literature until March 2019 for relevant studies. The Jadad scale was used to assess the quality of each study. A total of 48 studies out of 1402 met the inclusion criteria and were included in our systematic review and 16 of them were entered in meta-analysis. The pooled estimate from the random-effect model showed cocoa consumption significantly reduced malondialdehyde (SMD: -0.71; 95 % CI, -1.41 to -0.01; P = 0.048) and 8-iso-prostaglandin F2α (WMD: -43.76; 95 % CI, -76.25 to -11.28; P = 0.008) but not the other markers of oxidative stress. Our findings support the concept that cocoa consumption plays an important role in the human metabolic pathway through reducing the oxidative stress. In order to draw a firm link between cocoa and oxidative stress, more clinical trials with adequate sample size and sufficient follow-up periods are warranted.

Meta-Analysis
BACKGROUND
Diabetes nephropathy (DN), as one of the common complications of diabetes, is characterized by persistent albuminuria, decreased glomerular filtration rate, and elevated arterial blood pressure. At present, Xuebijing injection is widely used in the treatment of DN. However, few systematic reviews and meta-analysis related to Xuebijing injection intervention in DN were published. In order to more systematically and objectively evaluate the clinical efficacy of Xuebijing injection intervention in DN, we conducted systematic reviews and meta-analysis to verify it.
OBJECTIVE
The purpose of the research was to systematically evaluate the clinical efficacy of Xuebijing injection combined with alprostadil in the treatment of diabetic nephropathy.
METHODS
We searched the China National Knowledge Infrastructure (CNKI), China Biomedical Database (SinoMed), Weipu Database (VIP), Wanfang Database, PubMed, The Cochrane Library, Embase, Web of Science and other databases by computer, and searched the randomized controlled trials of Xuebijing injection combined with alprostadil in the treatment of DN at home and abroad from the establishment of the database to 2022. The main outcome indicators included blood glucose, and the secondary outcome indicators included blood lipid, renal function, urinary protein, and safety. Two evaluators independently screened the literature, extracted the data and evaluated the risk of bias in the included studies. RevMan 5.3 software was used to analyze the data.
RESULTS
A total of 14 randomized controlled trials were included, including 1233 cases, 618 cases in the treatment group and 615 cases in the control group. The results of meta-analysis demonstrated that compared with the control group, the treatment group could effectively reduce fasting plasma glucose [mean difference [MD] = -1.90, 95% CI (-2.40, -1.40), P < .00001], glycosylated hemoglobin A1c [MD = -2.38, 95% CI (-2.51, -2.25), P < .00001], 2h postprandial blood glucose [MD = -2.92, 95% CI (-3.95, -1.89), P < .00001], triacylglycerol [MD = -1.08, 95% CI (-1.66, -0.50), P = .0003], total cholesterol [MD = -1.17, 95% CI (-1.39, -0.95), P < .00001], low-density lipoprotein cholesterol [MD = -1.19, 95% CI (-1.60, -0.78), P < .00001], high-density lipoprotein cholesterol [MD = 0.32, 95% CI (0.23, 0.42), P < .00001], serum creatinine [MD = -42.95, 95% CI (-57.46, -28.43), P < .00001], blood urea nitrogen [MD = -2.24, 95%CI (-2.62,-1.86), P < .00001], blood β2 microglobulin [SMD = -1.49, 95% CI (-1.70, -1.28), P < .00001], urine β2 microglobulin [SMD = -0.81, 95% CI (-1.04, -0.58), P < .00001], 24-hour urinary protein quantification [MD = -0.20, 95% CI (-0.26, -0.14), P < .00001], urinary albumin excretion rate [SMD = -1.15, 95% CI (-1.38, -0.93), P < .00001].
CONCLUSION
Xuebijing injection combined with alprostadil has more advantages in treating DN compared to routine Western medicine.

AIMS
Sodium-glucose cotransporter-2 inhibitors (SGLT2is) have a protective cardiorenal effect in type 2 diabetes. This systematic review examines the effects of SGLT2is on clinical biomarkers of inflammation and oxidative stress.
METHODS
A search of Medline, Embase, Web of Science, and The Cochrane Library was performed examining changes in selected clinical biomarkers for inflammation: c-reactive protein (CRP), adiponectin, interleukin-6 (IL6), tumour necrosis factor-alpha (TNF-α), and oxidative stress: 8-iso-prostaglandin F2α (8-iso-PGF2α) and 8-hydroxy-2'-deoxyguanosine (8-OHdG). Quality of evidence was evaluated using the GRADEpro tool and risk of bias was assessed using the Cochrane RoB 2 and ROBINS-I tools.
RESULTS
A total of 23 (15 randomised, 8 observational) heterogeneously-designed clinical studies were identified (1654 patients, 24 weeks median follow-up). Consistent reductions were observed for CRP (10/12 studies), IL6 (5/5 studies), TNFα (3/4 studies), 8-iso-PGF2α (3/4 studies) and 8-OHdG (2/2 studies), and a consistent increase in adiponectin (6/8 studies). Change in serum CRP following SGLT2is appear to be independent of change in HbA1c and other study design and clinically relevant variables.
CONCLUSIONS
There is heterogeneous, yet consistent data supporting the beneficial effects of SLGT2is on inflammatory and oxidative stress. Change in serum CRP appears to be independent of change in HbA1c.

PURPOSE
Performing bioinformatics analyses using trabecular meshwork (TM) gene expression data in order to further elucidate the molecular pathogenesis of primary open-angle glaucoma (POAG), and to identify candidate target genes.
METHODS
A systematic search in Gene Expression Omnibus and ArrayExpress was conducted, and quality control and preprocessing of the data was performed with ArrayAnalysis.org. Molecular pathway overrepresentation analysis was performed with PathVisio using pathway content from three pathway databases: WikiPathways, KEGG and Reactome. In addition, Gene Ontology (GO) analysis was performed on the gene expression data. The significantly changed pathways were clustered into functional categories which were combined into a network of connected genes.
RESULTS
Ninety-two significantly changed pathways were clustered into five functional categories: extracellular matrix (ECM), inflammation, complement activation, senescence and Rho GTPase signalling. ECM included pathways involved in collagen, actin and cell-matrix interactions. Inflammation included pathways entailing NF-κB and arachidonic acid. The network analysis showed that several genes overlap between the inflammation cluster on the one hand, and the ECM, complement activation and senescence clusters on the other hand. GO analysis, identified additional clusters, related to development and corticosteroids.
CONCLUSION
This study provides an overview of the processes involved in the molecular pathogenesis of POAG in the TM. The results show good face validity and confirm findings from histological, biochemical, genome-wide association and transcriptomics studies. The identification of known points of action for drugs, such as Rho GTPase, arachidonic acid, NF-κB, prostaglandins and corticosteroid clusters, supports the value of this approach to identify potential drug targets.
