COVID-19 Vaccinations, Infections, and Outcomes Among 784 People Living with HIV.

Introduction: Variants of COVID-19 are responsible for 700 million infections and 7 million deaths worldwide. Vaccinations have high efficiency in preventing infection and secondary benefits of reducing COVID-19 hospital admissions, attenuating disease severity and duration of illness. Conflicting reports were published regarding COVID-19 among PLWH.

Characteristics of patients with spontaneous resolution of sesame allergy.

Background: The prevalence of sesame allergy is increasing; strict avoidance is the mainstay of therapy. Lately, sesame oral immunotherapy was presented as an alternative treatment, with a high rate of success. Therefore, data on the natural history and the clinical characteristics of patients with persistent sesame allergy are important for the management of patients with sesame allergy.

End-expiratory lung volume remains stable during N MBW in healthy sleeping infants.

We have previously shown that functional residual capacity (FRC) and lung clearance index were significantly greater in sleeping healthy infants when measured by N (nitrogen) washout using 100% O (oxygen) versus 4% SF (sulfur hexafluoride) washout using air. Following 100% O exposure, tidal volumes decreased by over 30%, while end-expiratory lung volume (EELV, i.e.

Aging leads to impaired epicutaneous sensitization that causes attenuated allergy and pulmonary inflammation in mice.

Aging is associated with altered decreased barrier function in the skin, which can lead to different types of immunoglobulin E (IgE)-mediated sensitization to environmental allergens. Yet, allergen-specific respiratory sensitization among the elderly is not well described. The aim of this study was to investigate the effect of aging on allergic pulmonary inflammation induced by epicutaneous sensitization of mechanically irritated skin in mice.
