Read on to find out the difference between roseola and measles rashes. Roseola, also known as roseola infantum, sixth disease, or exanthema subitum, is a viral infection that typically affects children.

causes of precapillary pulmonary hypertension :: Article Creator Long-term Oxygen Therapy Improves Exercise Capacity In PH Long-term oxygen improves exercise capacity in people with pulmonary arterial hypertension (PAH) or chronic thromboembolic pulmonary hypertension (CTEPH), a study suggests. Twelve weeks of supplemental oxygen led to a significant and clinically relevant improvements in exercise capacity, as assessed with the six-minute walking distance test (6MWD), by 42 meters (about 138 feet) over the distances walked at start of the study, "Long-term oxygen therapy in precapillary pulmonary hypertension — SOPHA study," which was published in Scientific Reports. PH is marked by high blood pressure in the pulmonary arteries, the blood vessels that transport blood from the heart to the lungs. Precapillary PH includes PAH, where blood pressure increases due to the narrowing of pulmonary arteries, along with CTEPH, a rare form of p...
