Widely used e-cigarette flavoring impairs lung function

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.

Sleep Apnea Raises Your Risk of Sudden Cardiac Death

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.

Memo to Underwriters:

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

RESULTS:

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).

CONCLUSIONS:

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.

Drink More Green Tea

Conclusion

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.
