Part C — Application (30 points, 6 points each)
Write 5-7 complete sentences with specific reference to chapter content, primary literature citations, and methodological framings where asked.
21. ARDSNet 2000 low tidal volume protocol as Master's foundational anchor. Walk the ARDS Network 2000 NEJM trial design (RCT comparing 6 mL/kg predicted body weight versus 12 mL/kg tidal volume in 861 ARDS patients), findings (22% versus 40% mortality, absolute reduction 9%), and downstream impact (ARDSnet protocol as standard of care for two decades). Articulate refinements — Amato 2015 NEJM driving pressure framework, Guerin 2013 NEJM PROSEVA prone positioning, ECMO via CESAR/EOLIA for selected severe refractory ARDS. Position ARDSNet 2000 alongside other Master's clinical-translational foundational anchors.
22. Severe asthma biologics revolution at Master's translational depth. Walk the biologics class development — omalizumab (anti-IgE) for moderate-to-severe allergic asthma, mepolizumab/reslizumab/benralizumab (anti-IL-5 pathway) for eosinophilic asthma, dupilumab (anti-IL-4Rα) for T2-high asthma, tezepelumab (anti-TSLP) for cross-phenotype severe asthma. Apply the T2-high versus T2-low biomarker-guided care framework. How has this transformed severe asthma management from the historical corticosteroid-centered framework to the modern phenotype-targeted biologic-centered framework?
23. Opioid respiratory depression public health translation cross-coach integration. Walk the opioid public-health framework at Master's translational depth — opioid epidemiology three-wave framework (prescription opioid era, heroin transition, illicit fentanyl Wave 3), opioid respiratory depression mechanism (MOR activation on preBötC inspiratory neurons → reduced inspiratory drive → apnea), naloxone harm reduction (Walley 2013 BMJ, 2023 OTC approval). Cross-reference Brain Master's Lesson 1 (SUD treatment with methadone/buprenorphine/naltrexone framework) and Sleep Master's Lesson 1 (BZ-opioid co-prescribing risk at FDA 2016 boxed warning depth per Sun 2017 BMJ). How do the three chapters jointly hold the opioid public health crisis at Master's depth?
24. Breathwork research at methodological-evidence-threshold framework. Walk the Balban 2023 Cell Reports Medicine trial design (4-condition RCT, 5 min daily over 28 days, 114 adults) and findings (cyclic sighing strongest mood improvement, modest effect sizes). Apply the methodological-evidence-threshold framework — what does the trial actually demonstrate (daily-practice 28-day mood effects, not acute single-session effects or clinical depression treatment)? Position breathwork research OUTSIDE established depression treatment landscape per the methodological-evidence-threshold framework, contrasting with light therapy (Lam 2016) and exercise (Schuch 2016) positioned WITHIN. Identify the wellness-industry overclaim pattern operating in breathwork space.
25. Occupational lung disease emerging epidemics and environmental pulmonology. Walk two emerging occupational lung disease epidemics — engineered stone silicosis (workers cutting artificial stone countertops, accelerated silicosis at younger ages, Australia 2024 ban) and CWP modern Appalachian resurgence (Blackley 2018 JAMA documenting accelerated progression). Cross-reference Pope 1995 NEJM air pollution mortality framework and the environmental justice intersection. Apply the structural public health framing — these are not individual exposure decisions but workplace and environmental exposure systems requiring policy intervention. How does the Master's chapter build the occupational and environmental pulmonology framework?
