BACKGROUND The prevalence of sleep-disordered breathing (SDB) in patients with prolonged mechanical ventilation (PMV) is unknown. The aim of this study was to assess the frequency of SDB in patients admitted to a long-term acute care (LTAC) hospital who weaned from PMV. METHODS Retrospective chart review was conducted of all PMV patients who had in-patient polysomnography (PSG) between Janua...

There are several models of premotor cortex contributions to sensorimotor behavior. For instance, the ventral premotor cortex (PMv) appears to be involved in processing visuospatial object properties for grasping, whereas the dorsal premotor cortex (PMd) is involved in using arbitrary rules to guide advance motor planning. These models have focused on individual movements. Here, we examine the ...

INTRODUCTION In coronary artery bypass (CABG) surgery, the common complications are the need for reintubation, prolonged mechanical ventilation (PMV) and death. Thus, a reliable model for the prognostic evaluation of those particular outcomes is a worthwhile pursuit. The existence of such a system would lead to better resource planning, cost reductions and an increased ability to guide preventi...

OBJECTIVE Hypothyroidism is cited as an uncommon cause of ventilator-dependent respiratory failure. The objective of this study was to determine the incidence of hypothyroidism in patients with respiratory failure, receiving prolonged mechanical ventilation (PMV) with failure to wean, referred to a regional weaning center (RWC) for weaning. SETTING RWC. DESIGN Retrospective. METHODS Medic...

In this issue of RESPIRATORY CARE, Kojicic and colleagues describe long-term survival in patients who underwent tracheostomy for anticipated or prolonged mechanical ventilation (PMV) in Olmsted County, Minnesota.1 The study confirmed that approximately 10% of patients with invasive mechanical ventilation undergo tracheotomy and that overall 1-year mortality in that population is still substanti...

The amount of body fat and the energy balance are important factors that influence the timing of puberty and the normal reproductive function. Leptin is a key hormone that conveys to the central nervous system information about the individual energy reserve and modulates the hypothalamus-pituitary-gonad (HPG) axis. Recent findings suggest that the ventral premammillary nucleus (PMV) mediates th...

Motor-based brain-computer interface (BCI) use is a learned skill that has been shown to involve multiple cortical areas, though it only explicitly requires modulation of a small area of cortical tissue. The roles being played by these other areas have not yet been determined. In this study, using an electrocorticographic (ECoG) model, we apply a novel computational approach to quantifying the ...

Isıl konfor, insanın yapısı, yaşı, cinsiyeti gibi kişisel parametrelerin yanı sıra çevresel parametrelere de bağlıdır. Isıtma, soğutma ve havalandırma sistemlerinin çalışma şekli dış hava sıcaklıkları ısıl konfor için önemli parametrelerdir. Fanger deneysel çalışmalar sonucu “tahmini ortalama oy (PMV)” olarak adlandırılan bir gösterge oluşturmuş PMV=0’ı en iyi değer belirlemiştir. Bu çalışmada,...

ASHRAE 55-2004 and ISO 7730 standards failed to predict actual comfort level and lead to oversize design of HVAC system. So proper thermal environment monitoring is an important subject to have right size of HVAC systems. A prototype thermal EM system has been developed. Thermal environment parameters such as: temperature, relative humidity, CO and CO2 are measured by using the developed system...

The parieto-frontal circuit underlying grasping, which requires the serial involvement of anterior intraparietal area (aIPs) and ventral premotor cortex (PMv), has been recently extended enlightening role dorsal (PMd). supplementary motor (SMA) also suggested to encode grip force for grasping actions; furthermore, both PMd SMA are known play a crucial in imagery. Here, we aimed at assessing dyn...
