Effects of monensin inclusion and cattle subspecies on utilization of bermudagrass hay (13.7% CP, 77.3% NDF, and 38.8% ADF) were evaluated using ruminally cannulated steers (5 [BI] and 5 [BT]; 398 kg BW). Subspecies were concurrently subjected to a 2-period, 2-treatment crossover design. Treatments were 0 (CON) or 200 mg·steer·d monensin (MON) in 0.91 kg dried distillers' grains with solubles. Periods were 70 d in length: 20 d of adaptation, 22 d of sample collection, and 28 d for withdrawal of treatment...

INTRODUCTION: Removal of pulmonary secretions in mechanically ventilated patients usually requires suction with closed catheter systems or flexible bronchoscopes. Manual ventilation is occasionally performed during such procedures if clinicians suspect inadequate ventilation. Suctioning can also be performed with the ventilator entirely disconnected from the endotracheal tube (ETT). The aim of this study was to investigate if these two procedures generate negative airway pressures, which may contribute to atelectasis...

Positioned at the intersection of the head, body and forelimb, the pectoral girdle has the potential to function in both feeding and locomotor behaviours-although the latter has been studied far more. In ray-finned fishes, the pectoral girdle attaches directly to the skull and is retracted during suction feeding, enabling the ventral body muscles to power rapid mouth expansion. However, in sharks, the pectoral girdle is displaced caudally and entirely separate from the skull (as in tetrapods), raising the question of whether it is mobile during suction feeding and contributing to suction expansion...

Measuring a disconnected streambed seepage flux using a seepage meter can give important streambed information and help understanding groundwater-surface water interaction. In this study, we provide a correction for calculating the seepage flux rate with the consideration of air compressibility inside the manometer of the Bouwer and Rice seepage meter. We notice that the effect of air compressibility in the manometer is considerably larger when more air is included in the manometer. We find that the relative error from neglecting air compressibility can be constrained within 5% if the manometer of the Bouwer and Rice seepage meter is shorter than 0...

Once incision and drainage of fascial space abscess is performed, irrigation of deep spaces with saline and antibiotic solution should be done daily for effective elimination or reduction of infection. Various advocated aids for irrigation into deeper areas are: small pediatric nasogastric feeding tubes, French catheter, polyethylene irrigation tubes and scalp vein infusion set. All these aids have major inherent disadvantages like, they tend to kink inside the deep spaces limiting the reach of irrigating solution into deeper spaces, are not readily available in dental departments and have to be discarded after every use...

PURPOSE: We conducted a prospective, randomized study to evaluate the necessity of drainage after thyroid surgery. METHODS: The patients (n = 215) were randomly assigned to be treated with suction drains (group 1; n = 108) or not (group 2; n = 107). RESULTS: The postoperative pain scores were significantly lower in the non-drained group than in the drained group of patients at postoperative days 0 and at 1. Hematomas, seromas, wound infections, transient biochemical hypoparathyroidism, and transient damage of the recurrent laryngeal nerve occurred more frequently in the drained group than in the non-drained group...

This protocol describes 3D bioprinting of cardiac tissue without the use of biomaterials, using only cells. Cardiomyocytes, endothelial cells and fibroblasts are first isolated, counted and mixed at desired cell ratios. They are co-cultured in individual wells in ultra-low attachment 96-well plates. Within 3 days, beating spheroids form. These spheroids are then picked up by a nozzle using vacuum suction and assembled on a needle array using a 3D bioprinter. The spheroids are then allowed to fuse on the needle array...

BACKGROUND: Patients with acquired brain injury (ABI) often require long periods of having a tracheostomy tube for airway protection and prolonged mechanical ventilation. It has been recognized that fast and safe decannulation improves outcomes and facilitates the recovery process. Nevertheless, few studies have provided evidence for decannulation criteria, despite the high prevalence of ABI subjects with tracheostomies. The aim of our study was to assess which clinical parameters are the best predictors for decannulation in subjects with ABI...

BACKGROUND: Flexible bronchoscopy (FB) in intubated patients on mechanical ventilation increases airway resistance. During FB, two ventilatory strategies are possible: maintaining tidal volume (VT) while maintaining baseline CO2 or allowing reduction of VT. The former strategy carries risk of hyperinflation due to expiratory flow limitation with FB. The aim of the authors was too study end expiratory lung volume (EELV) during FB of intubated subjects while limiting VT. METHODS: We studied 16 subjects who were intubated on mechanical ventilation and required FB...

INTRODUCTION: Pneumonia is the third most common postoperative complication. However, its epidemiology varies widely and is often difficult to assess. For a better understanding, we utilized two national databases to determine the incidence of postoperative pneumonia after various surgical procedures. Specifically, we used the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) and the Nationwide Inpatient Sample (NIS) to determine the incidence and yearly trends of postoperative pneumonia following orthopaedic, urologic, otorhinolaryngologic, cardiothoracic, neurosurgery, and general surgeries...

The paediatric intensive care unit (PICU) provides care to critically ill neonates, infants and children. These patients are vulnerable and susceptible to the environment surrounding them, yet there is little information available on indoor air quality and factors affecting it within a PICU. To address this gap in knowledge we conducted continuous indoor and outdoor airborne particle concentration measurements over a two-week period at the Royal Children's Hospital PICU in Brisbane, Australia, and we also collected 82 bioaerosol samples to test for the presence of bacterial and viral pathogens...
