In a randomized trial of 24 elderly people with essential hypertension (12 in each group), one group spent 7 days and nights in a broad‑leaved evergreen forest and the other stayed in an urban area. After the trip, the forest group had a significant drop in blood pressure compared with…
In a randomized trial of 20 healthy adults, researchers recorded EKGs during a 3-minute baseline, a 15-minute massage, and a 3-minute postmassage period. Moderate pressure massage raised the high-frequency (HF) heart-rate variability measure and lowered the LF/HF ratio, which the authors say indicates increased parasympathetic (vagal) activity peaking in the…
The results suggested that CFS is associated with IFOF WM deficits which continue to deteriorate at an abnormal rate. J. Magn. Reson. Imaging 2016;44:1301-1311.
This small cross-sectional study compared 33 regular yoga practitioners with 35 non‑practitioners aged 17–30. The yoga group had a lower resting heart rate (about 69 vs 81 bpm) and a smaller blood‑pressure response on the sustained handgrip test (about 10.2 vs 16.3), differences the authors report as statistically significant. Other…
Researchers tested 33 healthy people to see how lightheadedness and brain blood flow are linked. During hyperventilation that lowered CO2, people's reports of lightheadedness matched drops in cerebral blood flow velocity (CBFv). After a few such episodes, a smell that had been paired with hyperventilation later triggered more lightheadedness and…
Ibogaine is a psychoactive herbal medication with alleged antiaddiction properties. We report a case of ibogaine intoxication mimicking Long-QT syndrome resulting in ventricular flutter and nearby cardiac arrest. A 61-year-old man experienced massive QT prolongation and ventricular flutter at a rate of 270 beats per minute requiring defibrillation after ingestion…
