PARTNER is a prospective, phase II-III, randomized controlled clinical trial that recruited patients with triple-negative breast cancer, who were germline BRCA1 and BRCA2 wild type. Here we report the results of the trial. Patients (n = 559) were randomized on a 1:1 basis to receive neoadjuvant carboplatin-paclitaxel with or without 150 mg olaparib twice daily, on days 3 to 14, of each of four cycles (gap schedule olaparib, research arm) followed by three cycles of anthracycline-based chemotherapy before surgery.

Article Synopsis
  • Researchers previously identified a stem cell-derived additive that enhances heart protection during cold ischemia, aimed at improving procedures in cardiac transplantation.
  • The study involved eight pigs, comparing two methods of cold ischemic time (CIT)—one utilizing chest cavity storage and the other external storage—while measuring their heart performance.
  • Results showed that the external storage method had longer CIT and different temperature conditions, but both methods maintained similar initial heart performance metrics.

Bidirectional interactions between the immune system and the gut microbiota are key contributors to various physiological functions. Immune-associated diseases such as cancer and autoimmunity, and efficacy of immunomodulatory therapies, have been linked to microbiome variation. Although COVID-19 infection has been shown to cause microbial dysbiosis, it remains understudied whether the inflammatory response associated with vaccination also impacts the microbiota.

Objective: Sepsis is a leading cause of mortality. Predicting outcomes is challenging and few biomarkers perform well. Defects in the renin-angiotensin system (RAS) can predict clinical outcomes in sepsis and may outperform traditional biomarkers.

Age-associated B cells (ABC) accumulate with age and in individuals with different immunological disorders, including cancer patients treated with immune checkpoint blockade and those with inborn errors of immunity. Here, we investigate whether ABCs from different conditions are similar and how they impact the longitudinal level of the COVID-19 vaccine response. Single-cell RNA sequencing indicates that ABCs with distinct aetiologies have common transcriptional profiles and can be categorised according to their expression of immune genes, such as the autoimmune regulator (AIRE).

Purpose: Community engagement is essential in effective public health programs. This paper illustrates the methods used to engage community in the development of a multi-level implementation intervention to address cancer disparities related to hereditary cancer syndromes.

Methods: Implementation Mapping (IM), was used to guide the co-creation of an intervention.

In Canada, nurse practitioners (NPs) have been recognized as advanced practice nurses (APNs) for two decades. During this time, the number of NP education programs has increased and transitioned from post-baccalaureate to graduate and post-graduate level. In 2018, the Canadian Association of Schools of Nursing's (CASN) board of directors passed a motion to provide a voluntary NP accreditation program.

George Daicoff was a true pioneer who excelled in patient care, research, teaching, and advocacy; he performed cardiac surgery on thousands. He trained at Mayo Clinic under the tutelage of John Kirklin in 1966. He served on the faculty at University of Florida from 1967 to 1977 and became Chief of Thoracic and Cardiovascular Surgery at University of Florida.

Nurses in advanced practice roles have existed in Canada for over 100 years, yet only in the last two decades, have nurse practitioners (NPs) been recognized as advanced practice nurses (APNs). During this time, NP educational programs have increased and transitioned from post-baccalaureate level to graduate level. Legislation and national NP regulatory approval processes have contributed to existing barriers to NP role implementation and full scope of practice.

The growing unmet demand for suitable organ donors increases each year. Despite relative contraindications for thoracic organ donation after previous cardiac surgery, experienced programmes and surgeons can successfully utilise the lungs from select donors who have undergone prior cardiac surgery. This is the first reported case of double lung en bloc procurement from a donor who had a previous arterial switch operation as an infant.

Introduction: accurate and timely laboratory diagnosis of yellow fever (YF) is critical to the Eliminate Yellow Fever Epidemics (EYE) strategy. Gavi, the Vaccine Alliance recognized the need to support and build capacity in the national and regional laboratories in the Global YF Laboratory Network (GYFLN) as part of this strategy.

Methods: to better understand current capacity, gaps and needs of the GYFLN laboratories in Africa, assessments were carried out in national and regional reference laboratories in the 25 African countries at high risk for YF outbreaks that were eligible for new financial support from Gavi.

Nanowarming of cryopreserved organs perfused with magnetic cryopreservation agents (mCPAs) could increase donor organ utilization by extending preservation time and avoiding damage caused by slow and nonuniform rewarming. Here, we report formulation of an mCPA containing superparamagnetic iron oxide nanoparticles (SPIONs) that are stable against aggregation in the cryopreservation agent VS55 before and after vitrification and nanowarming and that achieve high-temperature rise rates of up to 321°C/min under an alternating magnetic field. These SPIONs and mCPAs have low cytotoxicity against primary cardiomyocytes.

Article Synopsis
  • Primary immunodeficiency (PID) leads to serious health issues like recurrent infections, autoimmune diseases, and cancers, presenting challenges for diagnosis and treatment, especially when patients are adults with no known family history.
  • A study analyzing whole-genome sequencing in 1,318 PID patients found that 10.3% had identified mutations in known genes, along with new candidate genes and deletions in regulatory regions that contribute to PID.
  • The research also explored the genetic interplay of high-penetrance variants with common variants, shedding light on how these factors affect the diverse symptoms and severity seen in PID, highlighting the potential of whole-genome sequencing in improving diagnosis and understanding of immune disorders.

A 29-year old male with recurrent respiratory and skin infections, anaemia and neutropaenia during childhood required immunoglobulin replacement for antibody deficiency from age 16. He remained relatively well until age 28 when he presented with a two-week history of fatigue, sore throat, fever and productive cough. He was found to have EBV viraemia and splenomegaly and a diagnosis of EBV-driven lymphoproliferative disease was made following bone marrow trephine.

IL-6 excess is central to the pathogenesis of multiple inflammatory conditions and is targeted in clinical practice by immunotherapy that blocks the IL-6 receptor encoded by We describe two patients with homozygous mutations in who presented with recurrent infections, abnormal acute-phase responses, elevated IgE, eczema, and eosinophilia. This study identifies a novel primary immunodeficiency, clarifying the contribution of IL-6 to the phenotype of patients with mutations in , and genes encoding different components of the IL-6 signaling pathway, and alerts us to the potential toxicity of drugs targeting the IL-6R.

Background: Yellow fever (YF) is a viral hemorrhagic fever, endemic in the tropical forests of Africa and Central and South America. The disease is transmitted by mosquitoes infected with the yellow fever virus (YFV). Ethiopia was affected by the largest YF outbreak since the vaccination era during 1960-1962.

Objectives: Clinical experience is an essential component of nurse practitioner (NP) education that relies heavily on preceptors. Recruitment and retention of preceptors is challenging due to many variables that can affect NP education and practice. We surveyed Canadian NP programs to understand their preceptorship structures, how they support preceptorship, and to identify gaps and challenges to recruitment and retention of preceptors.
