DRAGON - 8U Nanosatellite Orbital Deployer

The Space Research Centre of the Polish Academy of Sciences (SRC PAS) together with Astronika company have developed an Orbital Deployer called DRAGON for ejection of the Polish scientific nanosatellite BRITE-PL Heweliusz (Fig. 1). The device has three unique mechanisms including an adopted and scaled lock and release mechanism from the ESA Rosetta mission MUPUS instrument. This paper discusses major design restrictions of the deployer, unique design features, and lessons learned from development through testing

Pharmacotherapy of atrial fibrillation in COVID-19 patients

The coronavirus pandemic disease 2019 (COVID-19) has changed the face of contemporary medicine. However, each and every medical practitioner must be aware of potential early and late complications of COVID-19, its impact on chronic diseases — especially ones as common as atrial fibrillation (AF) — and the possible interactions between patients’ chronic medications and pharmacotherapy of COVID-19. Patients with AF due to comorbidities and, often, elderly age are assumed to be at a higher risk of a severe course of COVID-19. This expert consensus summarizes the current knowledge regarding the pharmacotherapy of AF patients in the setting of the COVID-19 pandemic. In general, anticoagulation principles in quarantined or asymptomatic individuals remain unchanged. Nevertheless, it is advisable to switch from vitamin K antagonists to non-vitamin K antagonist oral anticoagulants (NOACs) whenever possible due to their consistent benefits and safety with fixed dosing and no monitoring. Additionally, in AF patients hospitalized due to mild or moderate COVID-19 pneumonia, we recommend continuing NOAC treatment or to switching to low-molecular-weight heparin (LMWH). On the other hand, in severely ill patients hospitalized in intensive care units, intravenous or subcutaneous dosing is preferable to oral, which is why the treatment of choice is either LMWH or unfractionated heparin. Finally, particularly in critical scenarios, the treatment strategy in COVID-19 patients with AF should be individualized based on possible interactions between anticoagulants, antiarrhythmics, antivirals, and antibiotics. In this consensus, we also discuss how to safely perform COVID-19 vaccination in anticoagulated AF patients

Out-of-hospital cardiac arrest: Do we have to perform coronary angiography?

Out-of-hospital cardiac arrest (OHCA) remains a leading cause of global mortality, while survivors are burdened with long-term neurological and cardiovascular complications. OHCA management at the hospital level remains challenging, due to heterogeneity of OHCA presentation, the critical status of OHCA patients reaching the return of spontaneous circulation (ROSC), and the demands of post ROSC treatment. The validity and optimal timing for coronary angiography is one important, yet not fully defined, component of OHCA management. Guidelines state clear recommendations for coronary angiography in OHCA patients with shockable rhythms, cardiogenic shock, or in patients with ST-segment elevation observed in electrocardiography after ROSC. However, there is no established consensus on the angiographic management in other clinical settings. While coronary angiography may accelerate the diagnostic and therapeutic process (provided OHCA was a consequence of coronary artery disease), it might come at the cost of impaired post-resuscitation care quality due to postponing of intensive care management. The aim of the current statement paper is to discuss clinical strategies for the management of OHCA including the stratification to invasive procedures and the rationale behind the risk-benefit ratio of coronary angiography, especially with patients in critical condition

Effectiveness and safety of PCSK9 inhibitor therapy in patients with familial hypercholesterolemia within a therapeutic program in Poland: Preliminary multicenter data

Background: In Poland, treatment with proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors has become available free of charge in a therapeutic program. Assessed herein, is the efficacy and safety of alirocumab and evolocumab in patients with heterozygous familial hypercholesterolemia (FH).Methods: Data of 55 adult FH patients who participated in the program were analyzed upon meeting the criteria established by the Ministry of Health (low density lipoprotein cholesterol [LDL-C] above 160 mg/dL on max. tolerated statin dose and ezetimib). The efficacy of PCSK9 inhibitors in reducing LDL-C with drug administration every 2 weeks was assessed after 3 months and 1 year of therapy. A safety profile evaluation was performed at each visit. 48 patients completed the 3-month and 21 for the 1-year observation periods (34 patients treated with alirokumab and 14 with evolocumab).Results: The mean concentration of direct-measured LDL-C decreased from the initial level of 215.1 ± 74.5 mg/dL to 75.3 ± 64.1 mg/dL, i.e., by 65 ± 14% following 3 months of treatment. This effect was stable in 1-year observation (77.7 ± 72.8 mg/dL). Adverse effects were flu-like symptoms (13.0%), injection site reactions (11.1%), fatigue (5.6%) and musculoskeletal symptoms (5.6%). Seven patients failed to complete the 3-month treatment period due to side effects or non-compliance, and 1 patient failed to complete the 1-year treatment due to myalgia.Conclusions: This study confirmed high effectiveness of PCSK9 inhibitors in reducing LDL-C levels in patients with FH. Due to restrictive inclusion criteria with LDL-C threshold level > 160 mg/dL (> 4.1 mmol/L) required for participation in the therapeutic program, a relatively small number of FH patients were eligible for treatment
