Background The bedside fiber bronchoscope has been widely used in the diagnosis and treatment of respiratory disease. This study aims to assess the effect of using bedside fiber bronchoscope in sputum suction and alveolar lavage for treatment of stroke-associated pneumonia (SAP), compared with the use of conventional suction catheter. Methods One hundred and six patients with SAP were randomly divided into control group (n = 53) and experimental group (n = 53) for a controlled study. Patients in the two groups were conventionally treated with phlegm-resolving and anti-infective therapy...

The Greenland Shark ( Somniosus microcephalus ) is the most common bycatch in the Greenland halibut ( Reinhardtius hippoglossoides ) bottom longline fishery in Cumberland Sound, Canada. Historically, this inshore fishery has been prosecuted through the ice during winter but winter storms and unpredictable landfast ice conditions since the mid-1990s have led to interest in developing a summer fishery during the ice-free season. However, bycatch of Greenland shark was found to increase substantially with 570 sharks captured during an experimental Greenland halibut summer fishery (i...

PURPOSE OF REVIEW: As a flapless procedure, SMILE brings benefits to refractive surgery, such as lower corneal biomechanical impact, less dry eye risk and less stromal bed exposure. However, the longer learning curve can be a risk factor for complications. This article aims to discuss SMILE complications and proposes a categorized analysis of occurrences, dividing into two groups: intraoperative and postoperative complications. Among intraoperative, we also suggest a subdivision between those related to the laser (lenticule construction), tissue separation (lenticule dissection) and tissue removal (lenticule extraction)...

BACKGROUND: Adequate analgesia and sedation is crucial in critical care. There is little knowledge on the extent of painful and stressful procedures on children admitted to a paediatric intensive care unit (PICU) and its analgesic and/or sedative management. OBJECTIVE: The primary objective was to determine the number of painful and stressful procedures per patient per day in our PICU patients, including the numbers of attempts. A secondary objective was to map PICU nurses' perceptions of the painfulness of the included procedures...

The importance of enhancing sludge dewaterability is increasing due to the considerable impact of excess sludge volume on disposal costs and on overall sludge management. This study presents an innovative approach to enhance dewaterability of anaerobic digestate (AD) harvested from a wastewater treatment plant. The combination of zero valent iron (ZVI, 0-4.0g/g total solids (TS)) and hydrogen peroxide (HP, 0-90mg/g TS) under pH3.0 significantly enhanced the AD dewaterability. The largest enhancement of AD dewaterability was achieved at 18mg HP/g TS and 2...

Cuihong Zhou, Xintong Huang, Meng Zeng
Dehydrating large amounts of sludge produced by sewage treatment plants is difficult. Microwave pretreatment can effectively and significantly improve the dewaterability and hydrogen production of sludge subjected to anaerobic digestion. The aim of this study was to investigate the effects of different microwave conditions on hydrogen production from anaerobic digestion and dewaterability of sludge. Based on an analysis of the electric field distribution, a spiral reactor was designed and a continuous microwave system was built to conduct intermittent and continuous experiments under different conditions...

Preterm infants spend the early days of their lives in neonatal intensive care units, where they undergo many minor painful procedures. There are many nonpharmacologic methods that can effectively reduce the pain response of neonates who undergo routine procedures. This study aimed to investigate whether oral glucose and listening to lullabies could bring pain relief during the removal and reinsertion of the tracheal tube and also oronasopharyngeal suctioning in premature infants to whom nasal continuous positive airway pressure was applied...

This study is an assessment of the hydrothermal carbonisation of poultry slaughterhouse wastes sludge for the solid recovered fuel. The effects of hydrothermal carbonisation were evaluated by varying the reaction temperatures in the range of 170 °C-220 °C. After hydrothermal carbonisation was completed, the capillary suction time, time to filter, and particle size decreased by ranges of 170.4 to 25.9 s, 40 to 7.0 s, and 220 to 98 um, respectively, with increasing hydrothermal carbonisation temperature...

We study the flow injection of semiflexible polymers in a nanopore with a diameter smaller than the persistence length of the macromolecules. The suction model from de Gennes and Brochard is modified to take into account the effect of the rigidity of the polymer in the Odijk regime. We show that in this case of extreme confinement the flow threshold vanishes slowly and that in the limit of infinitely small nanopore the free energy barrier eventually disappears.

Whether alveolar liquid surface tension, T, is elevated in the acute respiratory distress syndrome (ARDS) has not been demonstrated in situ in the lungs. Neither is it known how exogenous surfactant, which has failed to treat ARDS, affects in situ T. We aim to determine T in an acid-aspiration ARDS model before and after exogenous surfactant administration. In isolated rat lungs, we combine servo-nulling pressure measurement and confocal microscopy to determine alveolar liquid T according to the Laplace relation...

Motivated by biotechnological prospects, there is increasing evidence that we may just be scraping the tip of the iceberg of poisonous marine invertebrates, among which the Polychaeta are promising candidates for bioprospecting. Here we show that an inconspicuous phyllodocid uses toxins in its uncanny feeding strategy. The worm, a jawless active predator characterised by its bright green colour, preys on larger invertebrates (including conspecifics) by extracting tissue portions with its powerful proboscis through suction...

Surgically induced fire is a life-threatening hazard; this topic has received little attention, although only 3 factors, the so-called fire triad, are needed for surgical fires to occur: an oxidizer, fuel and an ignition source. This systematic review aims to determine the impact of each component and to delegate every staff member an area of responsibility, thus ensuring patient health through prevention or protection. The trial was registered in Prospero CRD42018082656. A database search of eligible, preferably evidence-based studies was conducted...

Aim: Intensive application of highly concentrated antimicrobials during scaling and root planing may be hazardous if swallowed in quantity. This study evaluates two dental isolation systems for fluid leakage in conjunction with a sham treatment of scaling and root planing. Materials and methods: Eight volunteers were randomly assigned to wear a conventional rubber dam (RD) and a combined suction and isolation device (IsoLite® system [IL]) alternatively on contralateral maxillary and mandibular quadrants. RD was cut between the canine and the first molar and was fixed on the first molar with a rubber dam clamp and with a tissue adhesive (Histoacryl) on the gingiva...

The lack of direct measurement of left ventricular unloading is a significant impediment to the development of an automatic speed control system for continuous-flow left ventricular assist devices (cf-LVADs). We have developed an inlet cannula tip for cf-LVADs with integrated electrodes for volume sensing based on conductance. Four platinum-iridium ring electrodes were installed into grooves on a cannula body constructed from polyetheretherketone (PEEK). A sinusoidal current excitation waveform (250 μA pk-pk, 50 kHz) was applied across one pair of electrodes, and the conductance-dependent voltage was sensed across the second pair of electrodes...

Cell signalling and mechanics influence vascular pathophysiology and there is an increasing demand for in vitro model systems that enable examination of signalling between vascular cells under hemodynamic conditions. Current 3D vessel wall constructs do not recapitulate the mechanical conditions of the native tissue nor do they allow examination of cell-cell interactions under relevant hemodynamic conditions. Here, we describe a 3D microfluidic chip model of arterial endothelial and smooth muscle cells where cellular organization, composition and interactions, as well as the mechanical environment of the arterial wall are mimicked...

The rice crop and associated ecosystems constitute a rich mosaic of habitats that preserve a rich biological diversity. Spiders are an abundant and successful group of natural predators that are considered efficient in the biocontrol of the major insect pests in agroecosystems. Spider diversity in different stages of the rice crop growth from eastern Uruguay was analysed. Field study was developed on six rice farms with rotation system with pasture, installed during intercropping stage as cover crop. Six rice crops distributed in three locations were sampled with pitfall and entomological vaccum suction machine...

Baleen whales (Mysticeti) are the largest animals on Earth, thanks to their ability to filter huge volumes of small prey from seawater. Mysticetes appeared during the Late Eocene, but evidence of their early evolution remains both sparse and controversial [1, 2], with several models competing to explain the origin of baleen-based bulk feeding [3-6]. Here, we describe a virtually complete skull of Llanocetus denticrenatus, the second-oldest (ca. 34 Ma) mysticete known. The new material represents the same individual as the type and only specimen, a fragmentary mandible...

BACKGROUND: The complex nature of the Paediatric Intensive Care Unit (PICU) patient requires the bedside nurse to make rapid, complex decisions regarding endotracheal suction (ETS) interventions. It is not understood what influences nurses' decision making in the context of ETS, however, the actions of the clinician have a direct impact on the efficacy of the ETS event and patient outcomes. OBJECTIVES: To explore and describe the use of normal saline instillation and lung recruitment with paediatric ETS in a cohort of Australian nurses, and to identify factors that influence normal saline use with ETS...
