Characterization of the symptoms of neurogenic orthostatic hypotension and their impact from a survey of patients and caregivers

BMC Neurology, 2018
BackgroundNeurogenic orthostatic hypotension (nOH) results from impaired vasoconstriction due to dysfunction of the autonomic nervous system and is commonly associated with Parkinson disease (PD), multiple system atrophy (MSA), and pure autonomic failure.

Orthostatic Hypotension in the Hypertensive Patient.

American Journal of Hypertension, 2018
Orthostatic hypotension (OH) is an important and common medical problem, particularly in the frail elderly with multiple comorbidities and polypharmacy. OH is an independent risk factor for falls and overall mortality.

Impact of Discontinuation of Fall‐Risk‐Increasing Drugs on Falls in Multimorbid Older Patients With Polypharmacy

Journal of the American Geriatrics Society, EarlyView.
ABSTRACT Background Falls are a major concern in the older population. An important cause of falls is fall‐risk‐increasing drugs (FRID). However, it is not known if the discontinuation of FRID leads to a reduction of falls. Therefore, the aim of this study was to assess the association between discontinuation of FRID and the occurrence of falls and ...

Inverse Transition Learning: Learning Dynamics from Demonstrations [PDF]

arXiv
We consider the problem of estimating the transition dynamics $T^*$ from near-optimal expert trajectories in the context of offline model-based reinforcement learning. We develop a novel constraint-based method, Inverse Transition Learning, that treats the limited coverage of the expert trajectories as a \emph{feature}: we use the fact that the expert ...

A Hybrid Multi-Factor Network with Dynamic Sequence Modeling for Early Warning of Intraoperative Hypotension [PDF]

arXiv
Intraoperative hypotension (IOH) prediction using past physiological signals is crucial, as IOH can lead to inadequate organ perfusion, increasing the risk of severe complications and mortality. However, existing IOH prediction methods often rely on static modeling, overlooking the complex temporal dependencies and non-stationary nature of ...

Diabetic gastroenteropathy: Associations between gastrointestinal symptoms, motility, and extraintestinal autonomic measures

Neurogastroenterology &Motility, EarlyView.
We found no associations between gastrointestinal and extraintestinal measures of diabetic autonomic neuropathy. Nonetheless, gastrointestinal symptoms increased with the severity of cardiovascular autonomic neuropathy and were associated with gastrointestinal measures.

Validation of the neuropathological criteria of the fourth Consortium on dementia with Lewy Bodies in autopsy cases from psychiatric hospitals

Psychiatry and Clinical Neurosciences, EarlyView.
Aim The pathological criteria from the fourth Consortium on Dementia With Lewy bodies (DLB) in psychiatric cohorts has not been validated. Also, the pathological differences in prodromal DLB subtypes remain unclear. This study aimed to elucidate the clinicopathological features of patients with DLB in psychiatric hospitals.

Women in space: A review of known physiological adaptations and health perspectives

Experimental Physiology, EarlyView.
Abstract Exposure to the spaceflight environment causes adaptations in most human physiological systems, many of which are thought to affect women differently from men. Since only 11.5% of astronauts worldwide have been female, these issues are largely understudied.
