Worse lung function, more allergic sensitization but less blood eosinophilia in elderly patients with long-standing versus late-onset asthma.

Background: Asthma in the elderly is usually considered homogeneous and non-atopic.

Objective: To compare clinical, functional and immunological features between elderly asthmatics with long-standing asthma (LSA) and those with late-onset asthma (LOA).

Methods: Eighty-two asthmatics older than 64 were included into LSA (asthma onset before age 40;  = 46) and LOA (asthma onset from 40 years of age on;  = 36) groups.

Dendritic cell-based immunotherapy in non-small cell lung cancer: a comprehensive critical review.

Despite treatment advances through immunotherapies, including anti-PD-1/PD-L1 therapies, the overall prognosis of non-small cell lung cancer (NSCLC) patients remains poor, underscoring the need for novel approaches that offer long-term clinical benefit. This review examined the literature on the subject over the past 20 years to provide an update on the evolving landscape of dendritic cell-based immunotherapy to treat NSCLC, highlighting the crucial role of dendritic cells (DCs) in immune response initiation and regulation. These cells encompass heterogeneous subsets like cDC1s, cDC2s, and pDCs, capable of shaping antigen presentation and influencing T cell activation through the balance between the Th1, Th2, and Th17 profiles and the activation of regulatory T lymphocytes (Treg).

Development and validation of an asthma knowledge questionnaire for use in Brazil.

Objective: To develop and validate an asthma knowledge questionnaire for use in adult asthma patients in Brazil.

Methods: A 34-item self-report questionnaire was constructed and administered to adult asthma patients and adult controls. The maximum total score was 34.
