Comparative Study Clinical TrialVenturi mask adjuvant oxygen therapy in severe acute ischemic stroke.
The effect of oxygen therapy in acute ischemic stroke remains undetermined. ⋯ By using VM therapy with a fraction of inspired oxygen of 40%, there might be less mortality and comorbidities in treated patients who experienced a severe acute ischemic stroke. Further randomized confirmatory studies should explore the decreased mortality in patients who experience a severe acute ischemic stroke, especially in those with a large middle cerebral artery infarction who undergo VM therapy with a fraction of inspired oxygen of 40%.

Randomized Controlled Trial Comparative StudyTestosterone therapy in men with Parkinson disease: results of the TEST-PD Study.
Testosterone deficiency has been reported in patients with Parkinson disease (PD), Alzheimer disease, and Huntington disease. It is not known whether testosterone therapy (TT) in men with borderline hypogonadism and neurodegenerative diseases will be of substantial benefit. Previously, we reported that testosterone deficiency is more common in patients with PD compared with age-matched control subjects, and we also reported in 2 small open-label studies that some nonmotor symptoms responded favorably to TT. ⋯ Testosterone therapy was generally well tolerated in elderly men with PD and probable testosterone deficiency. While there was no significant difference in the motor and nonmotor scales between the TT and placebo groups at the end of 8 weeks compared with baseline, this may be due to several study limitations, including small sample size, a strong placebo effect with intramuscular therapy, and short follow-up that did not allow measurement of delayed effects of TT in some subjects. Until more definitive studies are reported, practitioners should be particularly cautious in treatment of low testosterone concentrations in men with PD and borderline testosterone deficiency, and careful consideration should be given to the risks vs the benefits of TT.
