The 2024 European Society of Cardiology guidelines for atrial fibrillation (AF) emphasize a patient-centered approach to management, structured around the AF-CARE pathway: Comorbidity and risk factor management (C), Avoiding stroke and thromboembolism (A), Reducing symptoms through rate and rhythm control (R), and Evaluation and dynamic reassessment (E). This framework ensures that comorbidities such as hypertension, heart failure, diabetes, and obesity are effectively managed to prevent disease progression and improve outcomes. A key principle of the guidelines is shared decision making involving patients, families, caregivers, and healthcare teams to ensure individualized care that reflects patient preferences.

Interest in remimazolam has surged in recent years, thanks to its advantageous pharmacologic profile. This ultra-short-acting benzodiazepine is noted for its rapid onset and termination of action, organ-independent elimination, availability of a reversal agent, and excellent hemodynamic stability. Although the use of remimazolam has been explored in various anesthesia settings and procedures, data on its application in cardiovascular anesthesia and catheterization laboratory procedures remain limited.

Objective: To examine the association of COVID-19 convalescent plasma transfusion with mortality and the differences between subgroups in hospitalized patients with COVID-19.

Patients And Methods: On October 26, 2022, a systematic search was performed for clinical studies of COVID-19 convalescent plasma in the literature from January 1, 2020, to October 26, 2022. Randomized clinical trials and matched cohort studies investigating COVID-19 convalescent plasma transfusion compared with standard of care treatment or placebo among hospitalized patients with confirmed COVID-19 were included.

Convalescent plasma is used to treat COVID-19. There are theoretical concerns about the impact of pro-coagulant factors in convalescent plasma on the coagulation cascade particularly among patients with severe COVID-19. The aim of this study was to evaluate the coagulation profile of COVID-19 convalescent plasma.

Background: The United States (US) Expanded Access Program (EAP) to coronavirus disease 2019 (COVID-19) convalescent plasma was initiated in response to the rapid spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of COVID-19. While randomized clinical trials were in various stages of development and enrollment, there was an urgent need for widespread access to potential therapeutic agents. The objective of this study is to report on the demographic, geographical, and chronological characteristics of patients in the EAP, and key safety metrics following transfusion of COVID-19 convalescent plasma.

Coagulopathy is common during left ventricular assist device (LVAD) implantation, treatment of which can be challenging given the often-limited ability for the right ventricle to accommodate volume transfusion after device initiation with 20% to 40% of patients developing right ventricular failure (RVF). Transfusion of plasma late on cardiopulmonary bypass (CPB) combined with ultrafiltration may replace clotting factors while reducing volume administration. We compared outcomes in patients undergoing LVAD implantation receiving plasma on CPB and ultrafiltration with traditional transfusion practices.

Successful therapeutics and vaccines for coronavirus disease 2019 (COVID-19) have harnessed the immune response to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Evidence that SARS-CoV-2 exists as locally evolving variants suggests that immunological differences may impact the effectiveness of antibody-based treatments such as convalescent plasma and vaccines. Considering that near-sourced convalescent plasma likely reflects the antigenic composition of local viral strains, we hypothesize that convalescent plasma has a higher efficacy, as defined by death within 30 days of transfusion, when the convalescent plasma donor and treated patient were in close geographic proximity.

Article Synopsis
  • The United States expanded access to convalescent plasma for COVID-19 through an EAP to address the urgent need for treatment as the pandemic affected vulnerable populations disproportionately.
  • The Mayo Clinic coordinated the program, allowing any US physician to enroll patients, while blood banks adapted quickly to supply convalescent plasma to hospitalized individuals.
  • From April to August 2020, over 105,000 patients were enrolled in the EAP, with a significant portion being older adults, males, and minorities, highlighting efforts to include underserved groups in the treatment process.

Objective: To assess the association between the preoperative model for end-stage liver disease (MELD) and MELD-XI (exclude international normalized ratio) score and outcomes in patients undergoing pericardiectomy for constrictive pericarditis.

Patients And Methods: Patients >18 years of age undergoing pericardiectomy for constrictive pericarditis between January 1, 2007, and October 12, 2017, were analyzed with data for MELD and MELD-XI score calculation within 30 days preoperatively. The association between the MELD and MELD-XI scoring systems and risk of postoperative outcomes was assessed in regression models adjusting for relevant covariates.

Background: Convalescent plasma has been widely used to treat coronavirus disease 2019 (Covid-19) under the presumption that such plasma contains potentially therapeutic antibodies to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that can be passively transferred to the plasma recipient. Whether convalescent plasma with high antibody levels rather than low antibody levels is associated with a lower risk of death is unknown.

Methods: In a retrospective study based on a U.

Objective: To provide an update on key safety metrics after transfusion of convalescent plasma in hospitalized coronavirus 2019 (COVID-19) patients, having previously demonstrated safety in 5000 hospitalized patients.

Patients And Methods: From April 3 to June 2, 2020, the US Food and Drug Administration Expanded Access Program for COVID-19 convalescent plasma transfused a convenience sample of 20,000 hospitalized patients with COVID-19 convalescent plasma.

Results: The incidence of all serious adverse events was low; these included transfusion reactions (n=78; <1%), thromboembolic or thrombotic events (n=113; <1%), and cardiac events (n=677, ~3%).

Importance: Passive antibody transfer is a longstanding treatment strategy for infectious diseases that involve the respiratory system. In this context, human convalescent plasma has been used to treat coronavirus disease 2019 (COVID-19), but the efficacy remains uncertain.

Objective: To explore potential signals of efficacy of COVID-19 convalescent plasma.

Unilateral cervical spinal cord hemisection at C2 (C2SH) interrupts descending bulbospinal inputs to phrenic motoneurons, paralyzing the diaphragm muscle. Recovery after C2SH is enhanced by brain derived neurotrophic factor (BDNF) signaling via the tropomyosin-related kinase subtype B (TrkB) receptor in phrenic motoneurons. The role for gene therapy using adeno-associated virus (AAV)-mediated delivery of TrkB to phrenic motoneurons is not known.

Patients undergoing radiofrequency ablation for treatment of atrial fibrillation may present critically ill with complications of atrial esophageal fistula, commonly manifesting as neurologic deficits and septicemia difficult to distinguish from other acute etiologies without a high index of suspicion. The temporal variability in fistula formation and symptom presentation, along with their nonspecific features, makes diagnosis often a late finding with historically high morbidity and mortality. We present a patient admitted to a medical intensive care unit with status epilepticus and recurrent positive blood cultures for organisms commonly associated with the gastrointestinal (GI) tract.

Trypanosoma cruzi's trypomastigotes are highly active and their incessant motility seems to be important for mammalian host cell infection. The kinetoplastid membrane protein-11 (KMP-11) is a protein expressed in all parasite stages, which induces a cellular and humoral immune response in the infected host, and is hypothesized to participate in the parasite's motility. An N-terminal peptide from KMP-11, termed K1 or TcTLE, induced polyclonal antibodies that inhibit parasitic invasion of Vero cells.

KMP-11 is a highly conserved protein of Trypanosoma cruzi implicated in parasite's motility. Here we show that K1, a peptide derived from KMP-11, induced polyclonal antibodies capable of decreasing T. cruzi infection in vitro.
