Short retrospective review of 77 cases of bacterial endocarditis, observed in the 1980-84 period, and diagnosed by means of echography and blood culture. Alfa haemolytic streptococcus strains were isolated (47.6% of 42 isolated strains) followed by Staphylococcus aureus (16.7%) and Staphylococcus epidermidis (11.9%). Positive bloodculture were more frequent in the patients with valvular prosthesis. The results are analysed and some comments are done.

Background: Allergic rhinitis (AR) represents a persistent inflammatory condition affecting the upper respiratory tract, characterized by abnormal initiation of the immunoglobulin E (IgE)-mediated cascade. Follicular helper T (Tfh) cells and regulatory T (Tfr) cells are pivotal in orchestrating the development of IgE production in AR patients. IL-35, an anti-inflammatory cytokine, secreted by various cellular subpopulations.

Department of Neonatology, Al Wakra Hospital, Hamad Medical Corporation, Doha, Qatar.
Background: Group B Streptococcus (GBS) is the most common cause of neonatal early onset sepsis in term infants and a major cause of late onset sepsis in both term and preterm infants.
Aim: To estimate the incidence of GBSS among neonates born in Qatar between July 2015 and June 2020 (5 years). A secondary aim was to describe the outcomes of the affected babies.

Background: Our aim was to develop a quantitative model for immediately estimating the risk of death and/or brain injury in late-onset sepsis (LOS) in preterm infants, based on objective and measurable data available at the time sepsis is first suspected (i.e., time of blood culture collection).

Innate Lymphoid Cells Unit, Bambino Gesù Children's Hospital, IRCCS, Rome, Italy.
The Innate Lymphoid Cells (ILCs) are a family of innate immune cells composed by the Natural Killer (NK) cells and the helper ILCs (hILCs) (ILC1, ILC2, ILC3), both developing from a common ILC precursor (ILCP) derived from hematopoietic stem cells (HSCs). A correct ILC reconstitution is crucial, particularly in patients receiving HSC transplantation (HSCT), the only therapeutic option for many adult and pediatric high-risk hematological malignancies. Indeed, mainly thanks to their cytotoxic activity, NK cells have a strong Graft-versus-Leukemia (GvL) effect.

de Duve Institute, Université catholique de Louvain, Brussels, Belgium. Electronic address:
Neutrophils were historically considered a homogenous population of cells with functions limited to innate immunity against external threats. However, with the rise of immunotherapy, recent works have shown that neutrophils are also important actors in immuno-oncology. In this context, neutrophils appear as a more heterogenous population of cells.
