RESUMO
High-risk pulmonary embolism (PE) is a life-threatening disease state with current guidelines recommending reperfusion therapy with systemic thrombolytics in addition to anticoagulation. This was a prospective observational cohort study with a historical control group comparing tenecteplase to alteplase for the treatment of PE or cardiac arrest with suspected PE. The primary outcome was the incidence of institutional protocol deviations defined as incorrect thrombolytic dose administered or the incorrect product compounded. Secondary outcomes included any bleeding event, major bleeding event, all-cause mortality, and for patients with a cardiac arrest, successful return of spontaneous circulation (ROSC). Fifty-four patients were included in the study. Protocol deviations occurred in one patient receiving tenecteplase and one patient receiving alteplase (4.0% vs 3.4%; P = 1.0). There was no difference in all-cause mortality (80% vs 86.2%; P = .72), any bleed (12% vs 13.8%; P = 1.0), major bleed (8.0% vs 6.9%; P = 1.0), or ROSC achievement (22.2% vs 28.6%; P = .73) when comparing tenecteplase to alteplase. Our study demonstrates that tenecteplase may be an alternative thrombolytic to alteplase for treatment of PE or cardiac arrest with suspected PE. Further studies comparing the different systemic thrombolytic agents for PE or cardiac arrest with suspected PE are needed.
RESUMO
Monoclonal antibody Proprotein Convertase Subtilisin/Kexin type 9 (PCSK9) inhibitors reduce total cholesterol (TC), low density lipoproteins (LDL), high density lipoproteins (HDL), and triglycerides (TG). We assessed the ability of berberine, a natural PCSK9 inhibitor, to reduce lipid concentrations either alone or combined with other nutraceuticals. We searched PubMed, Scopus and EMBASE from inception to September 30th, 2022 for randomized controlled trials (RCTs) assessing 8-18 wk of berberine therapy on. A total of 41 RCTs with 4,838 patients met our inclusion criteria. Berberine containing products significantly reduced TC (MD -17.42 mg/dL [95%CI: -22.91 to -11.93]), LDL (MD -14.98 mg/dL [95%CI: -20.67 to -9.28]), and TG (MD -18.67 mg/dL [95%CI: -25.82 to -11.51]) while raising HDL (MD 1.97 mg/dL [95%CI: 1.16 to 2.78]) versus control (I2 > 72% for all analyses). Products with berberine alone had less robust effects on TC (MD -12.08 mg/dL [95%CI: -21.79 to -2.37]), LDL (MD -9.26 mg/dL [95%CI: -20.31 to 1.78]), and HDL (MD 1.38 mg/dL [95%CI: -1.27 to 4.03]) but TG effects were similar (MD -17.40 mg/dL [95%CI: -32.57 to -2.23]). Berberine along with red yeast rice reduced TC (MD -19.62 mg/dL [95%CI: -28.56 to -10.68]) and LDL (MD -18.79 mg/dL [95%CI: -28.03 to -9.54]) as did combination therapy with Silybum maranium for TC (MD -31.81 mg/dL [95%CI: -59.88 to -3.73]) and LDL (MD -30.82 mg/dL [95%CI: -56.48 to -5.16]). Berberine, alone or with other nutraceuticals, can provide a modest positive impact on lipid concentrations.
