Letermovir Prophylaxis for Cytomegalovirus Infection in Children After Hematopoietic Cell Transplantation.

Background/aim: Cytomegalovirus (CMV) infection is one of the major causes of morbidity following hematopoietic cell transplantation (HCT). Allogeneic HCT (allo-HCT) recipients are at the highest risk of clinically significant CMV reactivation. While letermovir has been approved for prophylactic use in CMV seropositive adults, reports on pediatric data are very limited.

Clinical Insights to Complete and Incomplete Surgical Revascularization in Atrial Fibrillation and Multivessel Coronary Disease.

The Endocannabinoid System and Physical Activity-A Robust Duo in the Novel Therapeutic Approach against Metabolic Disorders.

Rapidly increasing worldwide prevalence of obesity and related pathologies encompassing coronary heart disease, hypertension, metabolic syndrome, or type 2 diabetes constitute serious threats to global health and are associated with a significantly elevated risk of premature death. Considering the enormous burden of these pathologies, novel therapeutic and preventive patterns are indispensable. Dysregulation of one of the most complex biological systems in the human body namely, the endocannabinoid system (ECS) may result in metabolic imbalance and development of insulin resistance, type 2 diabetes, or non-alcoholic fatty liver disease.

Assessment of anti-SARS-CoV-2 antibodies level in convalescents plasma.

Despite extensive vaccination, the quantity of patients infected with the SARS-CoV-2 virus and its variants continues to grow worldwide. Treating patients with a severe course of COVID-19 is a difficult challenge. One of the generally accepted and specific therapy methods is the use of plasma rich in anti-SARS-CoV-2 antibodies.

Concurrent subcutaneous and ocular infections with Dirofilaria repens in a Polish patient: a case report in the light of epidemiological data.

Dirofilariasis is an emerging zoonosis caused by nematodes of the genus Dirofilaria, most often D. repens and D. immitis.

Ecthyma gangrenosum as a serious complication of infection in departments of paediatric oncology.

In most cases is a consequence of bloodstream infection in immunodeficient patients. This bacterium is characterized by multi-drug resistance and has a number of mechanisms that allow it to survive even in extreme conditions. The disease is characterized by an aggressive course involving the skin and mucous membranes, leading to ulceration with signs of necrosis within 12 to 24 h.

Wide Fontanels, Delayed Speech Development and Hoarse Voice as Useful Signs in the Diagnosis of KBG Syndrome: A Clinical Description of 23 Cases with Pathogenic Variants Involving the Gene or Submicroscopic Chromosomal Rearrangements of 16q24.3.

KBG syndrome is a neurodevelopmental autosomal dominant disorder characterized by short stature, macrodontia, developmental delay, behavioral problems, speech delay and delayed closing of fontanels. Most patients with KBG syndrome are found to have a mutation in the gene or a chromosomal rearrangement involving this gene. We hereby present clinical evaluations of 23 patients aged 4 months to 26 years manifesting clinical features of KBG syndrome.

Meta-analysis of controlled studies on minimally interrupted vs. continuous use of non-vitamin K antagonist oral anticoagulants in catheter ablation for atrial fibrillation.

Aims: At present, there are no guideline recommendations for minimally interrupted use of non-vitamin K antagonist oral anticoagulants (mi-NOAC) during catheter ablation (CA) for atrial fibrillation (AF). Current evidence is predominantly based on observational studies, with continuous use of vitamin K antagonist in the control arm. This quantitative summary reflects the first high-level evidence on contemporary regimens, with continuous NOAC use (c-NOAC) as the current gold standard.

Invitation to participate in a multi-center study for validation of cerebral computed tomography angiography and computed tomography perfusion in the determination of cerebral circulatory arrest during brain death/death by neurological criteria diagnosis procedure in paediatric population below 12 years of age.

We would like to invite paediatric intensive care units (PICU) to join our multi-center trial concerning patient population < 12 y/o and aiming at: • validation of computed tomography angiography (CTA)/computed tomography perfusion (CTP) tests for brain death/death by neurological criteria (BD/DNC) diagnosis procedures, • validation of duplex Doppler insonation of extracranial segments of the internal cerebral arteries and the vertebral arteries for choosing an optimal time for CTA/CTP testing.

Impact of preoperative glycometabolic status on outcomes in cardiac surgery: Systematic review and meta-analysis.

Background: Historically, impaired glucose metabolism has been associated with early and late complicated clinical outcomes after cardiac surgery; however, such a condition is not specific to subjects with diabetes mellitus and involves a larger patient population.

Methods: Databases were screened (January 2000 to December 2020) to identify eligible articles; studies that evaluated the association between preoperative metabolic status, as assessed by glycosylated hemoglobin levels and clinical outcomes, were considered. The studies were stratified in thresholds by baseline glycosylated hemoglobin level (lower vs higher).

Methods: This multicenter all-comer registry included data of consecutive patients with CAP treated by CS implantation.

Metal allergy after the Nuss procedure for pectus excavatum: a review.

Minimally invasive repair of pectus excavatum (MIRPE) technique (the Nuss procedure) is a minimally-invasive method that is commonly used in the treatment of pectus excavatum. An allergic reaction to the metal alloy bar that is implanted in the thorax during the procedure is a reported complication. We briefly review current literature concerning epidemiology, mechanisms and research results of allergic reactions after Nuss bar implantation.

Impact of donor and recipient Epstein-Barr Virus serostatus on outcomes of allogeneic hematopoietic cell transplantation: a systematic review and meta-analysis.

Allogeneic hematopoietic cell transplant (allo-HCT) is a potentially curative therapeutic strategy that showed encouraging long-term outcomes in hematological diseases. A number of factors can influence post-transplant clinical outcomes. While Epstein-Barr virus (EBV) constitutes a trigger for development of various adverse conditions, no clinical study yet has been powered to assess the effect of EBV serostatus on the clinical outcomes in allo-HCT population.

Education and training programmes for infection prevention and control professionals: mapping the current opportunities and local needs in European countries.

Background: Studies have repeatedly highlighted the need for homogenisation of training content and opportunities in infection prevention and control (IPC) across European countries.

Objectives: To map current training opportunities for IPC professionals, define local needs and highlight differences, across 11 European countries (Cyprus, France, England, Germany, Greece, Italy, Netherlands, Poland, Romania, Spain, Switzerland).

Sources: From July 2018 to February 2019, IPC experts directly involved in IPC training and education in their countries and/or internationally were invited to complete a prespecified set of questions in order to provide a detailed description of IPC training opportunities and needs in their country.
