BACKGROUND: Current guidelines discourage prophylactic plasma use in non-bleeding patients. This study assesses global plasma transfusion practices in the intensive care unit (ICU) and their alignment with current guidelines. STUDY DESIGN AND METHODS: This was a sub-study of an international, prospective, observational cohort. Primary outcomes were in-ICU occurrence rate of plasma transfusion, proportion of plasma events of total blood products events, and number of plasma units per event. Secondary outcomes included transfusion indications, INR/PT, and proportion of events for non-bleeding indications. RESULTS: Of 3643 patients included, 356 patients (10%) experienced 547 plasma transfusion events, accounting for 18% of total transfusion events. A median of 2 (IQR 1, 2) units was given per event excluding massive transfusion protocol (MTP) and 3 (IQR 2, 6) when MTP was activated. MTP accounted for 39 (7%) of events. Indications of non-MTP events included active bleeding (54%), prophylactic (25%), and pre-procedure (12%). Target INR/PT was stated for 43% of transfusion events; pre-transfusion INR/PT or visco-elastic hemostatic assays (VHA) were reported for 73%. Thirty-seven percent of events were administered for non-bleeding indications, 54% with a pre-transfusion INR < 3.0 and 30% with an INR < 1.5. DISCUSSION: Plasma transfusions occurred in 10% of ICU patients. Over a third were given for non-bleeding indications and might have been avoidable. Target INR/PT was not stated in more than half of transfusions, and pre-transfusion INR/PT or VHA was not reported for 27%. Further research and education is needed to optimize guideline implementation and to identify appropriate indications for plasma transfusion.

INTRODUCTION/AIMS: Prospective, randomized, controlled trials of intravenous immunoglobulin (IVIG) maintenance therapy in myasthenia gravis (MG) are lacking. In this trial, we evaluated the safety and efficacy of caprylate/chromatography-purified IVIG; (IGIV-C) in patients with generalized MG undergoing standard care. METHODS: Sixty-two patients enrolled in this phase 2, multicenter, international, randomized trial (1:1 IGIV-C [2 g/kg loading dose; 1 g/kg every 3 weeks through week 21] or placebo). Efficacy was assessed by changes in Quantitative MG (QMG) score at week 24 versus baseline (primary endpoint) and percentage of patients with clinical improvement in QMG, MG Composite (MGC), and MG-Activities of Daily Living (MG-ADL) scores (secondary endpoints). Safety assessments reported all adverse events (AEs). RESULTS: The change in QMG at 24 weeks was -5.1 for IGIV-C and -3.1 for placebo (p = .187). Seventy percent of patients in the IGIV-C group had improvement in MG-ADL (≥2-point decrease) versus 40.6% in the placebo group (p = .025). Patients showing clinical improvement in QMG and MGC (≥3-point decrease) were 70.0% for IGIV-C versus 59.4% for placebo (p = .442) and 60.0% for IGIV-C versus 53.1% for placebo (p = .610). IGIV-C was well tolerated; serious AEs were similar between arms. Three of four MG exacerbations requiring hospitalizations occurred in the IGIV-C arm with one death. DISCUSSION: Several efficacy parameters showed numerical results greater than those seen in the placebo group. This was a small study and may have been underpowered to see significant differences. Additional studies may be warranted to fully determine the efficacy of IVIG maintenance therapy in MG.

Systematic strategies for preventing and treating esophagogastric variceal rebleeding (EVRB) are currently inadequate. This systematic review aimed to update this critical gap by searching contemporary studies from major guideline websites, databases, and professional associations focused on EVRB prevention in cirrhosis patients. Key findings highlight evaluation methods, risk management, preventive measures, health education, and follow-up strategies. Notably, a hepatic venous pressure gradient exceeding 18 mmHg is identified as a reliable predictor of gastroesophageal varices (GOV) rebleeding. Effective management of primary diseases is crucial, with methods including antiviral and anti-fibrotic therapies, alcohol avoidance, vaccination, and careful medication management. The combination of nonselective β-blockers (NSBBs) and endoscopic variceal ligation (EVL) is established as the gold standard for secondary EVRB prevention. For patients experiencing recurrent bleeding despite NSBBs and EVL, transjugular intrahepatic portosystemic shunt (TIPS) therapy is recommended. Surgical options, such as surgical shunt and devascularization, are advised for those unsuitable for endoscopic therapy or TIPS, particularly in Child-Pugh A and B patients unresponsive to treatment. Additionally, traditional Chinese medicine options, such as Fufang Biejia Ruangan Tablets, Fuzheng Huayu Capsules, and Anluo Huaxian Pills, have shown promise in improving hepatic fibrosis and GOV in cirrhotic patients. This review offers a comprehensive overview of current prevention and treatment strategies for EVRB, providing valuable insights for clinicians and healthcare professionals.

INTRODUCTION: Crystalloid and colloid solutions commonly used in intensive and perioperative care can affect haemocoagulation status. This in vitro study assessed the impact of Plasma-Lyte, albunorm 5%, and Gelaspan 4% solutions on primary and secondary haemostasis using rotational thromboelastometry and platelet function analyser. METHODS: In this prospective study, we examined blood samples from 20 healthy volunteers using rotational thromboelastometry and platelet function analyser. Simultaneously, we analysed the blood samples subjected to 10% dilution using Plasma-Lyte, albunorm 5%, and Gelaspan 4% solutions. RESULTS: Compared to controls, Plasma-Lyte shortened EXTEM-CT (p = 0.005) and reduced FIBTEM-MCF (p = 0.017). albunorm 5% prolonged EXTEM-CFT (p = 0.001), decreased EXTEM-alpha (p < 0.001) and MCF in EXTEM, INTEM, and FIBTEM tests (p < 0.001, p = 0.038, p = 0.001, respectively), along with MCE in the PLTEM test (p < 0.001). Gelaspan 4% also prolonged EXTEM-CFT (p < 0.001), decreased EXTEM-alpha (p < 0.001) and MCF in EXTEM, INTEM, and FIBTEM tests (p < 0.001, p < 0.001, p = 0.009, respectively), along with MCE in the PLTEM test (p < 0.001). Gelaspan 4% also reduced EXTEM-CT (p = 0.021). All solution prolonged CT in PFA Col/ADP (p = 0.003 for Plasma-Lyte, p < 0.001 for albunorm and Gelaspan) and albunorm 5% also prolonged CT in Col/Epi (p = 0.003). CONCLUSION: Plasma-Lyte had the least effect on secondary haemostasis, whereas albunorm 5% had the least effect among colloids. Gelaspan 4% adversely affected the propagation phase of coagulation, maximal strength and elasticity of the coagulum, and the level of functional fibrinogen. All solutions adversely affected platelet function in primary haemostasis, with Plasma-Lyte showing the least effect.

BACKGROUND: Androgen-receptor signaling inhibitors (ARSIs) significantly improve survival in systemic therapy for advanced/metastatic prostate cancer (PCa) patients; however possible central nervous system (CNS) toxicity is an unaddressed concern. We aimed to assess and compare the incidence of CNS-related adverse events (AEs) secondary to the treatment of PCa patients with different ARSIs. MATERIALS: In August 2023, a comprehensive seach was conducted in three databases for randomized controlled trials (RCTs) of PCa patients receiving ARSIs plus ADT. The primary endpoints included mental impairment, cognitive impairment, seizure, fatigue, and falls. RESULTS: Twenty-six RCTs, comprising 20,328 patients, were included in meta-analyses and network meta-analyses (NMAs). ARSIs increased the risk of mental impairment (RR: 1.72; 95% CI, 1.09-2.71), cognitive impairment (RR: 2.25; 95% CI, 1.78-2.86), seizure (RR: 2.20, 95% CI, 1.09-4.45), fatigue (RR: 1.31, 95% CI, 1.20-1.43), and falls (RR: 2.07, 95% CI, 1.60-2.67) compared to standard of care (SOC). Based on NMAs, Enzalutamide showed a significant increase in risk for all assessed CNS-related AEs, while Abiraterone demonstrated significant risk increases in cognitive impairment, fatigue, and falls. Conversely, Darolutamide did not exhibit significant increases in risk for any CNS-related AEs, except for fatigue. CONCLUSIONS: The addition of ARSIs to ADT increased all examined CNS-related AEs compared to SOC. Each ARSI is associated with a distinct profile of CNS-related AEs. Careful patient selection and monitoring for CNS sequelae is necessary to achieve the best quality of life in patients on ARSI + ADT for PCa.

BACKGROUND: Androgen-receptor pathway inhibitors (ARPIs) have dramatically changed the management of advanced/metastatic prostate cancer (PCa). However, their cardiovascular toxicity remains to be clarified. OBJECTIVE: To analyze and compare the risks of cardiovascular events secondary to treatment of PCa patients with different ARPIs. METHODS: In August 2023, we queried PubMed, Scopus, and Web of Science databases to identify randomized controlled studies (RCTs) that analyze PCa patients treated with abiraterone, apalutamide, darolutamide, and enzalutamide. The primary outcomes of interest were the incidence of cardiac disorder, heart failure, ischemic heart disease (IHD), atrial fibrillation (AF), and hypertension. Network meta-analyses (NMAs) were conducted to compare the differential outcomes of each ARPI plus androgen deprivation therapy (ADT) compared to standard of care (SOC). RESULTS: Overall, 26 RCTs were included. ARPIs were associated with an increased risk of cardiac disorders (RR: 1.74, 95% CI: 1.13-2.68, p = 0.01), heart failure (RR: 2.49, 95% CI: 1.05-5.91, p = 0.04), AF (RR: 2.15, 95% CI: 1.14-4.07, p = 0.02), and hypertension (RR: 2.06, 95% CI: 1.67-2.54, p < 0.01) at grade ≥3. Based on NMAs, abiraterone increased the risk of grade ≥3 cardiac disorder (RR:2.40, 95% CI: 1.42-4.06) and hypertension (RR:2.19, 95% CI: 1.77-2.70). Enzalutamide was associated with the increase of grade ≥3 AF(RR: 3.17, 95% CI: 1.05-9.58) and hypertension (RR:2.30, 95% CI: 1.82-2.92). CONCLUSIONS: The addition of ARPIs to ADT increases the risk of cardiac disorders, including IHD and AF, as well as hypertension. Each ARPI exhibits a distinct cardiovascular event profile. Selecting patients carefully and vigilant monitoring for cardiovascular issues is imperative for those undergoing ARPI + ADT treatment.

OBJECTIVES: The efficacy and safety of macitentan, an endothelin receptor antagonist, were assessed in a 52-week, prospective, multicenter, double-blind, randomized, placebo-controlled, parallel-group study assessing the efficacy and safety of macitentan in Fontan-palliated adult and adolescent patients (RUBATO-DB) and an open-label extension trial (RUBATO-OL). METHODS: Patients aged 12 years and older with New York Heart Association functional class II or III underwent total cavopulmonary connection more than 1 year before screening and showed no signs of Fontan failure/clinical deterioration. In RUBATO-DB, the primary efficacy end point was change in peak oxygen consumption from baseline to week 16; secondary end points were change from baseline over 52 weeks in peak oxygen consumption and change in mean count/minute of daily physical activity via accelerometer from baseline to week 16. Safety was assessed throughout both studies. RESULTS: In RUBATO-DB, 137 patients were randomized to macitentan 10 mg (n = 68) or placebo (n = 69); 92.7% completed 52-week double-blind treatment. At week 16, mean ± SD change in peak oxygen consumption was -0.16 ± 2.86 versus -0.67 ± 2.66 mL/kg/minute with macitentan versus placebo (median unbiased treatment difference estimate, 0.62 mL/kg/minute [99% repeated CI, -0.62 to 1.85]; P = .19). No treatment effect was observed in either of the secondary end points. During RUBATO-DB, most common adverse events with macitentan were headache, nasopharyngitis, and pyrexia. Across RUBATO-DB and RUBATO-OL, most common adverse events were COVID-19, headache, and fatigue. RUBATO-OL was prematurely discontinued because RUBATO-DB did not meet its primary or secondary end point. CONCLUSIONS: The primary end point of RUBATO-DB was not met; macitentan did not improve exercise capacity versus placebo in patients with Fontan palliation. Macitentan was generally well tolerated over long-term treatment.

OBJECTIVE: Ischemic complications account for significant patient morbidity following aneurysmal subarachnoid hemorrhage (aSAH). The Prevention and Treatment of Vasospasm with Clazosentan (REACT) study was designed to assess the safety and efficacy of clazosentan, an endothelin receptor antagonist, in preventing clinical deterioration due to delayed cerebral ischemia (DCI) in patients with aSAH. METHODS: REACT was a prospective, multicenter, randomized, double-blind, phase 3 study. Eligible patients had aSAH secured by surgical clipping or endovascular coiling, and had presented with thick and diffuse clot on admission CT scan. Patients were randomized (1:1 ratio) to 15 mg/hour intravenous clazosentan or placebo within 96 hours of the aSAH for up to 14 days, in addition to standard of care treatment including oral or intravenous nimodipine. The primary efficacy endpoint was the occurrence of clinical deterioration due to DCI up to 14 days after initiation of the study drug. The main secondary endpoint was the occurrence of clinically relevant cerebral infarction at day 16 after study drug initiation. Other secondary endpoints included clinical outcome assessed on the modified Rankin Scale (mRS) and the Glasgow Outcome Scale-Extended (GOSE) at week 12 post-aSAH. Imaging and clinical endpoints were centrally adjudicated. RESULTS: A total of 409 patients were randomized between February 2019 and May 2022 across 74 international sites. Three patients did not start study treatment and were not included in the analysis set. The occurrence of clinical deterioration due to DCI was 15.8% (32/202 patients) in the clazosentan group and 17.2% (35/204 patients) in the placebo group, and the difference was not statistically significant (relative risk reduction [RRR] 7.2%, 95% CI -42.6% to 39.6%, p = 0.734). A nonsignificant RRR of 34.1% (95% CI -21.3% to 64.2%, p = 0.177) was observed in clinically relevant cerebral infarcts treated with clazosentan (7.4%, 15/202) versus placebo (11.3%, 23/204). Rescue therapy was less frequently needed for patients treated with clazosentan compared to placebo (10.4%, 21/202 vs 18.1%, 37/204; RRR 42.6%, 95% CI 5.4%-65.2%). A nonsignificant relative risk increase of 25.4% (95% CI -10.7% to 76.0%, p = 0.198) was reported in the risk of poor GOSE and mRS scores with clazosentan (24.8%, 50/202) versus placebo (20.1%, 41/204) at week 12 post-aSAH. Treatment-emergent adverse events were similar to those reported previously. CONCLUSIONS: Clazosentan administered for up to 14 days at 15 mg/hour had no significant effect on the occurrence of clinical deterioration due to DCI. Clinical trial registration no.: NCT03585270 (ClinicalTrials.gov) EU clinical trial registration no.: 2018-000241-39 (clinicaltrialsregister.eu).

AIMS: Among patients with cardiogenic shock, immediate initiation of extracorporeal membrane oxygenation (ECMO) did not demonstrate any benefit at 30 days. The present study evaluated 1-year clinical outcomes of the Extracorporeal Membrane Oxygenation in the therapy of Cardiogenic Shock (ECMO-CS) trial. METHODS AND RESULTS: The ECMO-CS trial randomized 117 patients with severe or rapidly progressing cardiogenic shock to immediate initiation of ECMO or early conservative strategy. The primary endpoint for this analysis was 1-year all-cause mortality. Secondary endpoints included a composite of death, resuscitated cardiac arrest or implantation of another mechanical circulatory support device, duration of mechanical ventilation, and the length of intensive care unit (ICU) and hospital stays. In addition, an unplanned post-hoc subgroup analysis was performed. At 1 year, all-cause death occurred in 40 of 58 (69.0%) patients in the ECMO arm and in 40 of 59 (67.8%) in the early conservative arm (hazard ratio [HR] 1.02, 95% confidence interval [CI] 0.66-1.58; p = 0.93). The composite endpoint occurred in 43 (74.1%) patients in the ECMO group and in 47 (79.7%) patients in the early conservative group (HR 0.83, 95% CI 0.55-1.25; p = 0.29). The durations of mechanical ventilation, ICU stay and hospital stay were comparable between groups. Significant interaction with treatment strategy and 1-year mortality was observed in subgroups according to baseline mean arterial pressure (MAP) indicating lower mortality in the subgroup with low baseline MAP (<63 mmHg: HR 0.58, 95% CI 0.29-1.16; pinteraction = 0.017). CONCLUSIONS: Among patients with severe or rapidly progressing cardiogenic shock, immediate initiation of ECMO did not improve clinical outcomes at 1 year compared to the early conservative strategy. However, immediate ECMO initiation might be beneficial in patients with advanced haemodynamic compromise.

Cíl: V počtech mechanické trombektomie (MT) symptomatického uzávěru velké mozkové tepny u pacientů s akutní ischemickou cévní moz- kovou příhodou (iCMP) na počet obyvatel se řadí Česká republika na přední místa v Evropě. Cílem práce bylo na základě analýzy dat studie METRICS II (Mechanical Thrombectomy Quality Indicators Study in Czech Stroke Centers II) zhodnotit aktuální výsledky léčby iCMP a vývoj plnění indikátorů kvality napříč republikou. Sekundárním cílem práce byla subanalýza souboru z hlediska použité techniky MT a jejího vlivu na úspěšnost rekanalizace uzávěru velké mozkové tepny. Metodika: Národní prospektivní observační studie METRICS II probíhala v České republice od 1. ledna 2023 do 31. prosince 2023. Studie se zúčastnilo jedenáct z patnácti center provádějících MT. Všechna technická a klinická data byla sbírána prospektivně. Výsledky léčby iCMP byly následně srovnány s doporučenými hodnotami jednotlivých parametrů multioborového konsenzu a výsledky studie METRICS probíhající v roce 2019. Data vztahující se k vlastní technice MT v předním povodí byla podrobena subanalýze a statisticky zpracována z hlediska vlivu použité techniky na úspěšnost rekanalizace uzávěru velké mozkové tepny. Výsledky: V práci jsou analyzována data z jedenácti center, ve kterých byla mechanická trombektomie provedena celkem 1312 pacientům (51,1 % mužů) průměrného věku 70,9 roků (SD ± 12,7). Intravenózní trombolýzou (IVT) byli před MT léčeni 894 nemocní (68,2 %) a 426 (32,5 %) bylo sekundárně transportováno k MT z jiného centra. Získaná data z národní prospektivní observační studie METRICS II byla hodnocena jako celek i pro jednotlivá centra. Shoda výsledků péče s doporučeními navrženými multioborovým konsenzem byla velmi vysoká. Sedm center splnilo parametry všech doporučení. Ostatní centra nesplnila pouze ojedinělá kritéria a ve většině případů jen hraničně. Statistickým zpracováním souboru MT v přední cirkulaci byla prokázána signifikantní závislost mezi typem MT a dosažením rekanalizace (TICI 2b–3, p = 0,0004, resp. TICI 2c/3, p < 0,0001). Závěr: Výsledky studie METRICS II ukázaly vysokou kvalitu péče o pacienty s uzávěrem velké mozkové tepny léčených MT. Statistickým zpracováním souboru MT v přední cirkulaci byla prokázána signifikantní závislost mezi typem MT a dosažením rekanalizace. Pro skupinu pacientů, u kterých proběhla MT kombinací aspirace a rekanalizace za pomoci stentretrieveru sekundárně, byla nalezena signifikantně nižší úspěšnost rekanalizace uzávěru velké mozkové tepny.

Aim: The Czech Republic is among the leading countries in Europe in the number of mechanical thrombectomy (MT) procedures for symptomatic large vessel occlusion (LVO) in patients with acute ischemic stroke per population. The aim of this study was to evaluate the current outcomes of acute ischemic stroke treatment and the development of treatment quality indicators in the Czech Republic based on the analysis of data from the METRICS II study (Mechanical Thrombectomy Quality Indicators Study in Czech Stroke Centres II). The secondary aim of the study was to subanalyze the cohort in terms of the MT technique used and its impact on the success of recanalisation of the LVO. Methods: The national prospective observational study METRICS II was conducted in the Czech Republic from 1 January 2023 to 31 December 2023. Eleven of the 15 centres performing MT participated in the study. All technical and clinical data were collected prospectively. The results of ischemic stroke treatment were then compared with the recommended values of the individual parameters of the multidisciplinary consensus and the results of the METRICS study ongoing in 2019. Data related to the actual technique of MT in the anterior circulation were subanalyzed and statistically processed for the effect of the technique used on the success of recanalization of the LVO. Results: Data from 11 centres in which mechanical thrombectomy was performed on a total of 1312 patients (51.1% male) with a mean age of 70.9 years (SD ± 12.7) were analysed. IV thrombolysis prior MT was performed in 894 (68.2%) patients and 426 (32.5%) patients were transferred secondarily for MT from primary stroke centers to dedicated comprehensive centers. Data obtained from the national prospective observational METRICS II study were evaluated as a whole and for individual centers. The concordance of results with the recommendations of multi- society consensus was very high. Seven centers met the parameters of all recommendations. The remaining centers failed to meet only isolated criteria and only marginally. Statistical analysis of the anterior circulation MT cohort showed a significant relationship between MT type and achievement of recanalization (TICI 2b-3, p = 0.0004 and TICI 2c/3, p < 0.0001, respectively). Conclusion: The results of METRICS II showed a high quality of care for patients with large cerebral artery occlusion treated with MT. Statistical analysis of a cohort of anterior circulation MTs showed a significant relation- ship between the type of MT and the achievement of recanalisation. A significantly lower success rate of recanalization of LVO was found for the group of patients who underwent MT by a combination of aspiration and recanalization using a stent retriever secondarily.
