Promoting Health Across the Lifespan: Sleep Topics

This document contains six lesson plans. The first lesson plan is designed to introduce the importance of sleep habits and the effect of sleep on physical, mental, and emotional health. The second lesson plan is designed to develop a more comprehensive understanding of sleep habits and their relationship to health. The third lesson plan is designed to address sleep health behaviors and to encourage positive behavior change. The fourth lesson plan is designed to introduce the importance of sleep scheduling and healthy sleep habits. The fifth lesson plan is designed to introduce the importance of sleep scheduling for academic success. The sixth lesson plan is designed to introduce sleep tracking and sleep health habits through the use of a Fitbit or other self-tracking device. The content is intended for college-aged students and health care professionals. Each lesson plan has a topic overview, time and format information, Healthy People 2020 Objectives, National Health Education Standards information, learning objectives, key concepts and terms, materials needed, and teaching steps. This material was developed by Plymouth State University students as a part of their coursework for Promoting Health Across the Lifespan, in fall 2016 with Dr. Barbara McCahan

Elevated levels of type 2 respiratory innate lymphoid cells in human infants with severe respiratory syncytial virus bronchiolitis

© 2019 by the American Thoracic Society. Rationale: Studies of the immune responses at the site of respiratory syncytial virus (RSV) infection are sparse despite nearly five decades of research into understanding RSV disease. Objectives: To investigate the role of mucosal innate immune responses to RSV and respiratory viral load in infants hospitalized with the natural disease. Methods: Cytokines, viral load, and type 2 innate lymphoid cell (ILC2) levels in nasal aspirates, collected within 24 hours of enrollment, from infants hospitalized with RSV infection were quantified. Measurements and Main Results: RSV severity in infants was categorized based on admission to the general ward (moderate) or the pediatric ICU (severe). Evaluable subjects included 30 patients with severe and 63 patients with moderate disease (median age, 74 d; range, 9-297 d). ILC2s were found in the nasal aspirates of patients with severe disease (0.051% of total respiratory CD451 cells) to a significantly greater extent than in patients with moderate disease (0.018%, P = 0.004). Levels of IL-4, IL-13, IL-33, and IL-1b were significantly higher in nasal aspirates of patients with severe disease compared with those of patients with moderate disease. Factors associated with disease severity were gestational age (odds ratio, 0.49; 95% confidence interval, 0.29-0.82; P = 0.007) and IL-4 (odds ratio, 9.67; 95% confidence interval, 2.45-38.15; P = 0.001). Conclusions: This study shows, for the first time, that elevated levels of ILC2s is associated with infant RSV severity. The findings highlight the dominance of type-2 responses to RSV infection in infants and suggest an important role of ILC2 in shaping the immune response early during RSV infection

Respiratory syncytial virus disease severity is associated with distinct CD8\u3csup\u3e+\u3c/sup\u3e T-cell profiles

Copyright © 2020 by the American Thoracic Society. Rationale: Respiratory syncytial virus (RSV) causes significant morbidity and mortality in infants worldwide. Although T-helper type 2 (Th2) cell pathology is implicated in severe disease, the mechanisms underlying the development of immunopathology are incompletely understood. Objectives: We aimed to identify local immune responses associated with severe RSV in infants. Our hypothesis was that disease severity would correlate with enhanced Th2 cellular responses. Methods: Nasal aspirates were collected from infants hospitalized with severe (admitted to the pediatric ICU) or moderate (maintained in the general ward) RSV disease at 5 to 9 days after enrollment. The immune response was investigated by evaluating T-lymphocyte cellularity, cytokine concentration, and viral load. Measurements and Main Results: Patients with severe disease had increased proportions of CD8 (cluster of differentiation 8)- positive T cells expressing IL-4 (Tc2) and reduced proportions of CD8+ T cells expressing IFNγ (Tc1). Nasal aspirates from patients with severe disease had reduced concentrations of IL-17. Patients with greater frequencies of Tc1, CD8+ T cells expressing IL-17 (Tc17), and CD4+ T cells expressing IL-17 (Th17) had shorter durations of hospitalization. Conclusions: Severe RSV disease was associated with distinct T-cell profiles. Tc1, Tc17, and Th17 were associated with shorter hospital stay and may play a protective role, whereas Tc2 cells may play a previously underappreciated role in pathology
