Radiation induced lymphopenia - a possible critical factor in current oncological treatment.

Background: The effect of ionizing radiation on the immune system during the treatment of malignant tumors has long remained a point of great interest. This issue is currently gaining importance, especially in connection with the advancing development and availability of immunotherapeutic treatment. During cancer treatment, radiotherapy has the ability to influence the immunogenicity of the tumor by increasing the expression of certain tumor-specific antigens.

Unusual local epidemic of paediatric respiratory syncytial virus during a time of global pandemic.

Background: Western Australia (WA) public health measures to eradicate SARS-CoV-2 resulted in a secondary reduction in paediatric respiratory syncytial virus (RSV) admissions. Following an absent expected 2020 winter peak, RSV-positive admissions surged during the summer of 2020.

Aim: This report examines the number of RSV-positive admissions and severities across 36 months to better understand this out-of-season epidemic.

Clinical, molecular, and pathological investigations of ovine pulmonary adenocarcinoma in the middle of Iraq.

Background: Ovine pulmonary adenocarcinoma (OPA), caused by Jaagsiekte sheep retrovirus (JSRV), is a contagious neoplastic disease in sheep characterized by chronic respiratory signs, inducing the transformation of secretory epithelial cells of the distal respiratory tract.

Aims: To perform clinical, epidemiological, and molecular studies with evaluation of some predisposing factors at the herd level of OPA infection in sheep in Al-Qadisiyah Province, Iraq.

Methods: The first step of the study was undertaken to evaluate the clinical cases of OPA in naturally infected sheep and correlation with observing respiratory signs.

Antibiotic Allergy Labels in Children Are Associated with Adverse Clinical Outcomes.

Background: Self-reported antibiotic allergies are common among hospitalized adults and children. However, there is a paucity of studies investigating the impact of an antibiotic allergy label in childhood.

Objective: To investigate the impact of antibiotic allergy labeling on clinical outcomes in children.
