Acute or persistent pain is a common occurrence and is often undertreated in older patients, especially those with an inability to communicate verbally (ICV). Regular comprehensive pain assessment, including self-rating and/or behavior scales, is critical but difficult to implement in routine clinical practice. The choice of the most appropriate scale for each patient is not easy, even for trained and skilled medical personnel. Indeed, the use of scales for short pain-behavior exposes to pain under-detection due to [...]

Chronically low blood pressure in older adults is associated with significantly increased long-term risks of dementia and all-cause mortality risk. Yet low blood pressure is generally not treated until an individual begins to experience the acute symptoms arising from very low cerebral perfusion. However, these acute symptoms, such as dizziness, balance difficulty, syncope, increased fall occurrence, vision impairment, and nausea, begin to occur only at very low blood pressure levels, such that mean arterial pressu [...]

Background: Both disrupted sleep and cognitive impairment are frequent in Parkinson’s disease (PD), but the evidence for a relationship between self-reported sleep disturbance and cognitive symptoms has been equivocal. If sleep symptoms differentially predict cognition in different subtypes, effects may be obscured in a general PD sample. Objective: First, to determine whether the associations between participant and disease variables, sleep symptoms and cognitive performance vary by subtype (younger and olde [...]

Small supernumerary marker chromosomes (sSMCs) are centric chromosome fragments additionally present in an otherwise normal human chromosome set that cannot be characterized by classical cytogenetic techniques alone. The majority of sSMCs are not yet related to a defined clinical phenotype. We compiled from the literature all 78 cases with multiple sSMCs per cell in which the chromosomal origin of the sSMCs has been identified. The number of sSMCs varies from 2 to 7; 64% have 2 sSMCs, 14% have 3 sSMCs, and the freq [...]

Cyclone separators are widely used in fluid catalytic cracking (FCC) units due to their lack of moving parts and relatively low-pressure drop. However, cyclone separators are prone to erosion-related issues, which is a major drawback. In this paper, a large eddy simulation (LES) of the particle-gas flow in a cyclone separator is investigated using a four-way Euler-Lagrange approach to model inter-particle collisions and the exchange of momentum between particles and fluid. The effects of inter-particle and particle [...]

Currently, geriatric medicine consists mainly of palliative treatment of the disorders that characterize senile decay. This is perfectly compatible with the prevailing view that aging is the inevitable result of multiple degenerative processes that cannot be treated effectively as they are, in themselves, inevitable and irreversible. This interpretation of aging clashes with a mass of data and arguments that, conversely, indicate that aging is a specific physiological function, favoured by supra-individual natural [...]

In September 2020 Hurricane Sally impacted two National Data Buoy Center (www.ndbc.noaa.gov) buoys near its track: 42040 in the deep water and 42012 in the shallow. Using pertinent air-sea interaction formulas from the literature, analyses of these buoy data indicate that, under fully rough airflow and wind sea conditions, U* = a Hs2 /Tp3 + b, here U* is the friction velocity, Hs is the significant wave height, and Tp is the peak wave period. It is found that a = 28 and b = 0.12 for the deep water environment, a = [...]
