Impact of the COVID-19 pandemic on rural obstetrics practices in New Mexico.

Context: During pregnancy, the immune system is altered, putting women at increased risk of complications from respiratory viruses. There is limited information about the effects of COVID-19 on pregnant women and obstetrics programs, particularly in rural regions.

Aims: Most published reports have been from large urban hospitals.

Post mortem evaluation of inflammation, oxidative stress, and PPARγ activation in a nonhuman primate model of cardiac sympathetic neurodegeneration.

Cardiac dysautonomia is a common nonmotor symptom of Parkinson's disease (PD) associated with loss of sympathetic innervation to the heart and decreased plasma catecholamines. Disease-modifying strategies for PD cardiac neurodegeneration are not available, and biomarkers of target engagement are lacking. Systemic administration of the catecholaminergic neurotoxin 6-hydroxydopamine (6-OHDA) recapitulates PD cardiac dysautonomia pathology.

In vivo imaging of inflammation and oxidative stress in a nonhuman primate model of cardiac sympathetic neurodegeneration.

Loss of cardiac postganglionic sympathetic innervation is a characteristic pathology of Parkinson's disease (PD). It progresses over time independently of motor symptoms and is not responsive to typical anti-parkinsonian therapies. Cardiac sympathetic neurodegeneration can be mimicked in animals using systemic dosing of the neurotoxin 6-hydroxydopamine (6-OHDA).
