INTRODUCTION
Although several lipid-lowering drugs are available, they are not sufficient for some patients. Bempedoic acid is a small molecule adenosine triphosphate-citrate lyase inhibitor indicated for the treatment of adults with hypercholesterolemia.
AREAS COVERED
We performed a systematic review of the literature using PubMed database, and the following keywords were used: 'bempedoic acid,' 'hypercholesterolemia,' and 'adenosine triphosphate citrate lyase.' The chemical property, mechanism of action, pharmacokinetics, clinical efficacy, and safety of bempedoic acid are introduced in this paper.
EXPERT OPINION
Bempedoic acid can modulate the metabolism of cholesterol. Clinical trials indicated that bempedoic acid could significantly reduce low-density lipoprotein cholesterol levels. Bempedoic acid was well tolerated.

Meta-Analysis
INTRODUCTION
Bempedoic acid (ETC-1002) is a first-in-class lipid-lowering agent recently approved by the United States (US) Food and Drug Administration (FDA) and the European Medicines Agency (EMA) for commercialization.
OBJECTIVE
The aim was to assess, through a systematic review of the literature and a meta-analysis of the available phase 2 and phase 3 clinical studies, the effect of treatment with bempedoic acid on serum uric acid (SUA) concentration. Secondary outcomes were treatment-related variations in creatinine serum level and incidence of gout.
METHODS
A systematic literature search in SCOPUS, PubMed Medline, ISI Web of Science and Google Scholar databases was conducted up to November 13th, 2019, in order to identify clinical trials potentially eligible for the meta-analysis. Effect sizes were expressed as absolute mean differences (MDs) and 95% confidence intervals (CIs).
RESULTS
Data were pooled from four clinical studies comprising ten arms, which included overall 3369 subjects, with 2213 in the active-treatment arm and 1156 in the control one. Meta-analysis of data suggested that treatment with bempedoic acid is related to a significant increase in SUA (MD 0.73, 95% CI 0.54-0.91, P < 0.001), serum creatinine (MD 0.04, 95% CI 0.03-0.05, P < 0.001) and the incidence of gout (odds ratio 3.56, 95% CI 1.24-10.19, P = 0.018). The relatively small number of subjects involved in the studies and the exclusion of patients with renal impairment from the clinical trials are important limitations of the meta-analysis. However, our data indicate potential safety issues with bempedoic acid and suggest that further studies are performed both to elucidate the pathogenetic mechanisms underlying these associations and to verify the long-term safety of this treatment.
CONCLUSION
Bempedoic acid seems to have unfavourable effects on SUA, creatinine level and the incidence of gout. The ongoing Cardiovascular Outcomes Trial (CVOT) will explore the longer-term safety of treatment with bempedoic acid and clarify its effect on cardiovascular events and mortality.

Meta-Analysis
BACKGROUND
Acne is an inflammatory disorder with a high global burden. It is common in adolescents and primarily affects sebaceous gland-rich areas. The clinical benefit of the topical acne treatments azelaic acid, salicylic acid, nicotinamide, sulphur, zinc, and alpha-hydroxy acid is unclear.
OBJECTIVES
To assess the effects of topical treatments (azelaic acid, salicylic acid, nicotinamide, zinc, alpha-hydroxy acid, and sulphur) for acne.
SEARCH METHODS
We searched the following databases up to May 2019: the Cochrane Skin Group Specialised Register, CENTRAL, MEDLINE, Embase, and LILACS. We also searched five trials registers.
SELECTION CRITERIA
Clinical randomised controlled trials of the six topical treatments compared with other topical treatments, placebo, or no treatment in people with acne.
DATA COLLECTION AND ANALYSIS
We used standard methodological procedures expected by Cochrane. Key outcomes included participants' global self-assessment of acne improvement (PGA), withdrawal for any reason, minor adverse events (assessed as total number of participants who experienced at least one minor adverse event), and quality of life.
MAIN RESULTS
We included 49 trials (3880 reported participants) set in clinics, hospitals, research centres, and university settings in Europe, Asia, and the USA. The vast majority of participants had mild to moderate acne, were aged between 12 to 30 years (range: 10 to 45 years), and were female. Treatment lasted over eight weeks in 59% of the studies. Study duration ranged from three months to three years. We assessed 26 studies as being at high risk of bias in at least one domain, but most domains were at low or unclear risk of bias. We grouped outcome assessment into short-term (less than or equal to 4 weeks), medium-term (from 5 to 8 weeks), and long-term treatment (more than 8 weeks). The following results were measured at the end of treatment, which was mainly long-term for the PGA outcome and mixed length (medium-term mainly) for minor adverse events. Azelaic acid In terms of treatment response (PGA), azelaic acid is probably less effective than benzoyl peroxide (risk ratio (RR) 0.82, 95% confidence interval (CI) 0.72 to 0.95; 1 study, 351 participants), but there is probably little or no difference when comparing azelaic acid to tretinoin (RR 0.94, 95% CI 0.78 to 1.14; 1 study, 289 participants) (both moderate-quality evidence). There may be little or no difference in PGA when comparing azelaic acid to clindamycin (RR 1.13, 95% CI 0.92 to 1.38; 1 study, 229 participants; low-quality evidence), but we are uncertain whether there is a difference between azelaic acid and adapalene (1 study, 55 participants; very low-quality evidence). Low-quality evidence indicates there may be no differences in rates of withdrawal for any reason when comparing azelaic acid with benzoyl peroxide (RR 0.88, 95% CI 0.60 to 1.29; 1 study, 351 participants), clindamycin (RR 1.30, 95% CI 0.48 to 3.56; 2 studies, 329 participants), or tretinoin (RR 0.66, 95% CI 0.29 to 1.47; 2 studies, 309 participants), but we are uncertain whether there is a difference between azelaic acid and adapalene (1 study, 55 participants; very low-quality evidence). In terms of total minor adverse events, we are uncertain if there is a difference between azelaic acid compared to adapalene (1 study; 55 participants) or benzoyl peroxide (1 study, 30 participants) (both very low-quality evidence). There may be no difference when comparing azelaic acid to clindamycin (RR 1.50, 95% CI 0.67 to 3.35; 1 study, 100 participants; low-quality evidence). Total minor adverse events were not reported in the comparison of azelaic acid versus tretinoin, but individual application site reactions were reported, such as scaling. Salicylic acid For PGA, there may be little or no difference between salicylic acid and tretinoin (RR 1.00, 95% CI 0.92 to 1.09; 1 study, 46 participants; low-quality evidence); we are not certain whether there is a difference between salicylic acid and pyruvic acid (1 study, 86 participants; very low-quality evidence); and PGA was not measured in the comparison of salicylic acid versus benzoyl peroxide. There may be no difference between groups in withdrawals when comparing salicylic acid and pyruvic acid (RR 0.89, 95% CI 0.53 to 1.50; 1 study, 86 participants); when salicylic acid was compared to tretinoin, neither group had withdrawals (both based on low-quality evidence (2 studies, 74 participants)). We are uncertain whether there is a difference in withdrawals between salicylic acid and benzoyl peroxide (1 study, 41 participants; very low-quality evidence). For total minor adverse events, we are uncertain if there is any difference between salicylic acid and benzoyl peroxide (1 study, 41 participants) or tretinoin (2 studies, 74 participants) (both very low-quality evidence). This outcome was not reported for salicylic acid versus pyruvic acid, but individual application site reactions were reported, such as scaling and redness. Nicotinamide Four studies evaluated nicotinamide against clindamycin or erythromycin, but none measured PGA. Low-quality evidence showed there may be no difference in withdrawals between nicotinamide and clindamycin (RR 1.12, 95% CI 0.49 to 2.60; 3 studies, 216 participants) or erythromycin (RR 1.40, 95% CI 0.46 to 4.22; 1 study, 158 participants), or in total minor adverse events between nicotinamide and clindamycin (RR 1.20, 95% CI 0.73 to 1.99; 3 studies, 216 participants; low-quality evidence). Total minor adverse events were not reported in the nicotinamide versus erythromycin comparison. Alpha-hydroxy (fruit) acid There may be no difference in PGA when comparing glycolic acid peel to salicylic-mandelic acid peel (RR 1.06, 95% CI 0.88 to 1.26; 1 study, 40 participants; low-quality evidence), and we are uncertain if there is a difference in total minor adverse events due to very low-quality evidence (1 study, 44 participants). Neither group had withdrawals (2 studies, 84 participants; low-quality evidence).
AUTHORS' CONCLUSIONS
Compared to benzoyl peroxide, azelaic acid probably leads to a worse treatment response, measured using PGA. When compared to tretinoin, azelaic acid probably makes little or no difference to treatment response. For other comparisons and outcomes the quality of evidence was low or very low. Risk of bias and imprecision limit our confidence in the evidence. We encourage the comparison of more methodologically robust head-to-head trials against commonly used active drugs.

Efficacy of Budesonide/Glycopyrronium/Formoterol Fumarate Metered Dose Inhaler (BGF MDI) Versus Other Inhaled Corticosteroid/Long-Acting Muscarinic Antagonist/Long-Acting β-Agonist (ICS/LAMA/LABA) Triple Combinations in COPD: A Systematic Literature Review and Network Meta-analysis.
INTRODUCTION
Triple inhaled corticosteroid/long-acting muscarinic antagonist/long-acting β-agonist (ICS/LAMA/LABA) combination therapy is recommended for patients with chronic obstructive pulmonary disease (COPD) who experience further exacerbations/symptoms on dual LAMA/LABA or ICS/LABA therapy. The relative efficacy of budesonide/glycopyrronium/formoterol fumarate metered dose inhaler 320/18/9.6 µg (BGF MDI) in COPD was compared with other ICS/LAMA/LABA fixed-dose and open combination therapies in a network meta-analysis (NMA).
METHODS
A systematic literature review was conducted to identify randomized controlled trials of at least 10-week duration, including at least one fixed-dose or open combination triple therapy arm, in patients with moderate to very severe COPD. Studies were assessed for methodological quality and risk of bias. A three-level hierarchical Bayesian NMA model was used to determine the exacerbation rate per patient per year as well as the following outcomes at week 24: changes from baseline in pre-dose trough forced expiratory volume in 1 s (FEV), post-dose peak FEV, and St. George's Respiratory Questionnaire (SGRQ) total score; proportion of SGRQ responders; and Transition Dyspnea Index focal score. Change from baseline in rescue medication use over weeks 12-24 was also analyzed. Meta-regression and sensitivity analyses were used to assess heterogeneity across studies.
RESULTS
Eighteen studies (n = 29,232 patients) contributed to the NMA. ICS/LABA dual combinations were combined as a single treatment group to create a connected network. Across all outcomes, there were no statistically significant differences between BGF MDI and other triple ICS/LAMA/LABA fixed-dose (fluticasone furoate/umeclidinium/vilanterol and beclomethasone dipropionate/glycopyrronium/formoterol fumarate) and open combinations with data available within the network. Results from sensitivity analyses and meta-regression were consistent with the base-case scenario.
CONCLUSION
This NMA suggested that BGF MDI has comparable efficacy to other ICS/LAMA/LABA fixed-dose and open triple combination therapies in reducing exacerbations and improving lung function and symptoms in patients with moderate to very severe COPD. Further research is warranted as additional evidence regarding triple therapies, especially fixed-dose combinations, becomes available.

Meta-Analysis
BACKGROUND
The evidence base for the widely accepted standard regimen of succinylcholine for rapid sequence induction (1.0 mg kg) remains unclear.
METHODS
We performed a systematic review and meta-analysis of randomized trials comparing any succinylcholine regimen with the standard regimen (1.0 mg kg) and reporting on intubating conditions and/or apnoea times. Results were expressed as absolute risk differences (ARD) for dichotomous data and mean differences (MD) for continuous data.
RESULTS
We retrieved six trials with relevant data of 864 patients (ASA 1 or 2, aged 18-65 years, body mass index < 30 kg m). Four regimens (0.3, 0.4, 0.5, 0.6 mg kg) were compared with 1.0 mg kg in at least three trials each, and three (0.8, 1.5, 2 mg kg) in one each. With 0.3 to 0.5 mg kg, the likelihood of excellent intubating conditions was significantly decreased (ARD - 22% to - 67%). With 0.3 and 0.4 mg kg, but not with 0.5, 0.6, 0.8, 1.5 and 2.0 mg kg, the likelihood of unacceptable intubating conditions was significantly increased (ARD + 22% and + 32%, respectively). With 2.0 mg kg, but not with 0.8 or 1.5 mg kg, the likelihood of excellent intubating conditions was significantly increased (ARD + 23%). Apnoea times were significantly shorter with regimens ≤0.8 mg kg (MD - 1.0 to - 3.4 min) but were not reported with 1.5 or 2.0 mg kg.
CONCLUSIONS
With succinylcholine regimens ≤0.5 mg kg, excellent intubating conditions are less likely and apnoea times are shorter, compared with 1 mg kg. With 0.3 and 0.4 mg kg, unacceptable intubating conditions are more common. Succinylcholine 1.5 mg kg does not produce more often excellent conditions compared with 1 mg kg, while 2.0 mg kg does, but the database with these regimens is weak and apnoea times remain unknown. Limited information size and strong statistical heterogeneity decrease the certainty of the evidence.

Gonzalez, AM and Trexler, ET. Effects of citrulline supplementation on exercise performance in humans: A review of the current literature. J Strength Cond Res 34(5): 1480-1495, 2020-L-citrulline, a nonessential amino acid found primarily in watermelon, has recently garnered much attention for its potential to augment L-arginine bioavailability, nitric oxide production, and exercise performance. Over the past decade, L-citrulline has received considerable scientific attention examining potentially ergogenic properties for both aerobic and anaerobic exercise performance. Thus, the purpose of this article is to summarize the theoretical rationale behind L-citrulline supplementation and to comprehensively review the available scientific evidence assessing the potential ergogenic value of L-citrulline supplementation on vascular function and exercise performance in humans. In addition, research that has investigated the potential synergistic effects of L-citrulline with other dietary ingredients (e.g., arginine, antioxidants, nitrates, and branched-chain amino acids) is reviewed. Oral L-citrulline and citrulline malate supplementation have shown to increase plasma citrulline and arginine concentrations, along with total nitrate and nitrite concentrations. Although blood flow enhancement is a proposed mechanism for the ergogenic potential of L-citrulline, evidence supporting acute improvements in vasodilation and skeletal muscle tissue perfusion after supplementation is scarce and inconsistent. Nevertheless, several studies have reported that L-citrulline supplementation can enhance exercise performance and recovery. Given the positive effects observed from some investigations, future studies should continue to investigate the effects of both acute and chronic supplementation with L-citrulline and citrulline malate on markers of blood flow and exercise performance and should seek to elucidate the mechanism underlying such effects.

Oral supplementation with iron is a standard intervention for treating or preventing iron deficiency with or without anemia. Over the last few decades, various forms of oral iron have been developed to improve treatment tolerability and iron bioavailability. In this review, we gathered research data regarding the use of iron protein succinylate since it was first marketed in the 1980s. Electronic databases - PubMed and the Cochrane Library - were searched for studies published up to March 2019. Clinical or observational studies reporting data on the tolerability of oral iron protein succinylate were included. Results were statistically described to evaluate and compare the efficacy and safety of iron protein succinylate with the comparators under study. Iron protein succinylate was investigated in 54 studies: 38 randomized clinical trials and 16 observational studies, with a total of 8454 subjects. Of them, 8142 were included in the efficacy analysis: patients were divided into three population subtypes: general ( = 1899), gynecological/obstetric ( = 5283), and pediatric ( = 960). In total, 6450 patients received iron protein succinylate, experiencing a significant change in hemoglobin and ferritin in all populations. The change in all parameters was similar or higher with iron protein succinylate compared to other iron treatments evaluated. Overall, study groups receiving iron protein succinylate reported the lowest rate of adverse events. Although all iron treatments analyzed are effective and safe, our results suggest that iron protein succinylate may be an excellent choice to treat iron deficiency and anemia due to its superior effectiveness and tolerability.

Aliskiren is an oral antihypertensive medication that acts by directly inhibiting renin. High levels of circulating renin and prorenin activate the pathological signaling pathway of fibrosis. This drug also reduces oxidative stress. Thus, the aim of this systematic review is to analyze experimental studies that show the actions of aliskiren on fibrosis. PubMed and LILACS databases were consulted using the keywords aliskiren and fibrosis within the period between 2005 and 2017. Fifty-three articles were analyzed. In the heart, aliskiren attenuated remodeling, hypertrophy, inflammatory cytokines, collagen deposition, and oxidative stress. In the kidneys, there was a reduction in interstitial fibrosis, the infiltration of inflammatory cells, apoptosis, proteinuria, and in the recruitment of macrophages. In diabetic models, an improvement in the albumin/creatinine relationship and in the insulin pathway in skeletal muscles was observed; aliskiren was beneficial to pancreatic function and glucose tolerance. In the liver, aliskiren reduced fibrosis, steatosis, inflammatory cytokines, and collagen deposition. In the lung and peritoneal tissues, there was a reduction in fibrosis. Many studies have reported on the beneficial effects of aliskiren on endothelial function and arterial rigidity. A reduction in fibrosis in different organs is cited by many authors, which complies with the results found in this review. However, studies diverge on the use of the drug in diabetic patients. Aliskiren has antifibrotic potential in several experimental models, interfering with the levels of fibrogenic cytokines and oxidative stress. Therefore, its use in diseases in which fibrosis plays an important pathophysiological role is suggested.

Meta-Analysis
The role of the direct renin inhibitor aliskiren in hypertension is not fully established and use of aliskiren in diabetic patients is especially controversial. A systematic review investigating both short-term diastolic and systolic blood pressure (DBP and SBP) reduction and long-term cardiovascular outcomes has not been conducted. Therefore, we aimed to fill this gap by investigating BP reduction, major cardiovascular outcomes, and mortality of aliskiren compared to other antihypertensive therapy. We searched PubMed and Embase databases for relevant randomized controlled trials (RCTs). Using a random-effects model, weighted mean difference (WMD) and relative risk (WRR) with 95% confidence interval (CI) were used to measure the effect of aliskiren therapy in the management of hypertension and major cardiovascular outcomes. Thirty seven RCTs with a total of 35,916 patients were included. Aliskiren induced slightly greater DBP and SBP reductions than other antihypertensive agents (WMD -0.77 mmHg, 95% CI [-2.01;0.46 mmHg] and WMD -1.14 mmHg, 95% CI [-2.78;0.50 mmHg], respectively). Aliskiren did not reduce total mortality or cardiovascular death. In patients with diabetes, aliskiren add-on therapy may have the potential to increase total mortality and cardiovascular death (WRR 1.06, 95% CI [0.88;1.28] and WRR 1.09, 95% CI [0.94;1.24], respectively). Despite superior BP-reducing effect, aliskiren is not recommended as first-line treatment in hypertensive patients as it does not reduce mortality and major cardiovascular outcomes. Dual renin-angiotensin-aldosterone system inhibition with aliskiren should be avoided in diabetic patients, while the use of aliskiren monotherapy remains to be investigated.

The British Journal of Dermatology Aug 2019The persistence and effectiveness of systemic therapies for moderate-to-severe psoriasis in current clinical practice are poorly characterized.
BACKGROUND
The persistence and effectiveness of systemic therapies for moderate-to-severe psoriasis in current clinical practice are poorly characterized.
OBJECTIVES
To systematically review observational studies investigating the persistence and effectiveness of acitretin, ciclosporin, fumaric acid esters (FAE) and methotrexate, involving at least 100 adult patients with moderate-to-severe psoriasis, exposed to therapy for ≥ 3 months.
METHODS
MEDLINE, Embase, the Cochrane Library and PubMed were searched from 1 January 2007 to 1 November 2017 for observational studies reporting on persistence (therapy duration or the proportion of patients discontinuing therapy during follow-up) or effectiveness [improvements in Psoriasis Area and Severity Index (PASI) or Physician's Global Assessment (PGA)]. This review was registered with PROSPERO, number CRD42018099771.
RESULTS
Of 411 identified studies, eight involving 4624 patients with psoriasis were included. Variations in the definitions and analyses of persistence and effectiveness outcomes prevented a meta-analysis from being conducted. One prospective multicentre study reported drug survival probabilities of 23% (ciclosporin), 42% (acitretin) and 50% (methotrexate) at 1 year. Effectiveness outcomes were not reported for either acitretin or ciclosporin. The persistence and effectiveness of FAE and methotrexate were better characterized, but mean discontinuation times ranged from 28 to 50 months for FAE and 7·7 to 22·3 months for methotrexate. At 12 months of follow-up, three studies reported that 76% (FAE), 53% (methotrexate) and 59% (methotrexate) of patients achieved ≥ 75% reduction in PASI, and one reported that 76% of FAE-exposed patients achieved a markedly improved or clear PGA.
CONCLUSIONS
The comparative persistence and effectiveness of acitretin, ciclosporin, FAE and methotrexate in real-world clinical practice in the past decade cannot be well described due to the inconsistency of the methods used.
