As of October 22, 2019, a total of 1,604 cases of EVALI, including 34 deaths, were reported to CDC. Based on data collected as of October 15, 2019, use of tetrahydrocannabinol (THC)-containing products in the 3 months preceding symptom onset was reported by 86% of patients. The median age of EVALI patients who survived was 23 years, and the median age of EVALI patients who died was 45 years.

Diseases Associated with VAPI
The following patterns of lung injury have been reported with VAPI:
■■Acute eosinophilic pneumonia
■■Acute lung injury and acute respiratory distress syndrome
■■Acute and subacute hypersensitivity pneumonitis
■■Acute eosinophilic pneumonia
■■Diffuse alveolar hemorrhage
■■Respiratory bronchiolitis-associated pneumonitis
This new study found that, in addition to how many breathing interruptions occur, how long each one lasts is also important. Patients with the shortest apneas were 31 percent more likely to die during the study’s decade of follow-up with participants. This held true for both male and female participants.
A new study has found that a common e-cigarette flavoring that has chemical characteristics similar to toxic chemicals found in cigarette smoke disrupts an important mechanism of the lungs’ antibacterial defense system.

In a five-year study of nearly 11,000 people, those with obstructive sleep apnea had a higher risk of sudden cardiac death. At greatest risk were those aged 60 and older with moderate to severe apnea (20 episodes an hour).
When their oxygen saturation levels dipped below 78 percent — preventing air from flowing into the lungs — their risk increased by 80 percent.

In case anyone asks why we are so harsh on untreated OSA quote this study.

During an average follow-up of 5.3 years, 142 patients had resuscitated or fatal SCD (annual rate 0.27%). In multivariate analysis, independent risk factors for SCD were age, hypertension, coronary artery disease, cardiomyopathy or heart failure, ventricular ectopy or nonsustained ventricular tachycardia, and lowest nocturnal O2sat (per 10% decrease, hazard ratio [HR]: 1.14; p = 0.029). SCD was best predicted by age >60 years (HR: 5.53), apnea-hypopnea index >20 (HR: 1.60), mean nocturnal O2sat <93% (HR: 2.93), and lowest nocturnal O2sat <78% (HR: 2.60; all p < 0.0001).
In a population of 10,701 adults referred for polysomnography, OSA predicted incident SCD, and the magnitude of risk was predicted by multiple parameters characterizing OSA severity. Nocturnal hypoxemia, an important pathophysiological feature of OSA, strongly predicted SCD independently of well-established risk factors. These findings implicate OSA, a prevalent condition, as a novel risk factor for SCD.
This study suggests that the consumption of green tea ≥2 times/d is associated with a reduced risk of COPD in Korean populations.
Consuming Green Tea at Least Twice Each Day Is Associated with Reduced Odds of Chronic Obstructive Lung Disease in Middle-Aged and Older Korean Adults
Drink more green tea.
Especially if you’re an older Korean.
The annual number of asthma deaths among persons aged 15–64 years has declined significantly from 1999 through 2016, most likely reflecting improvements in asthma management and effectiveness of prevention efforts
