Few studies have quantified nitrous oxide (NO) emissions from intensively managed turfgrass systems on golf courses. Fertilizer treatments consisting of urea with inhibitors of nitrification and urease (INU), polymer-coated urea (PCU), and uncoated balanced methylene urea (BMU) chain, which use different mechanisms to control the release of N substrate, were applied to a golf course fairway and rough three times during the 2011 growing season at a rate of 50 kg N ha per application. The vented chamber method was used to measure turf-soil-atmospheric NO exchange...

OBJECTIVES: The clinical outcome of children with severe acute myocarditis who require mechanical circulatory support is not well known. Therefore, we studied the survival and clinical courses of patients with acute fulminant myocarditis supported by extracorporeal life support (ECLS). METHODS: We performed a retrospective chart review of 13 consecutive children with acute fulminant myocarditis who were treated with ECLS between April 2013 and April 2015. Demographics, initial symptoms, laboratory results, management, clinical courses and last follow-up status were investigated...

Iloprost is a selective pulmonary vasodilator approved for inhalation by the Food and Drug Administration. Iloprost has been increasingly used in the management of critically ill neonates with hypoxic lung disease. This in vitro study was designed to test the hypothesis that aerosol drug delivery could be effectively administered to infants with both conventional ventilation and high-frequency oscillatory ventilation (HFOV). A neonatal test lung model configured with newborn lung mechanics was ventilated with a conventional ventilator and an HFOV with standard settings...

CPAP (continuous positive airway pressure) is to establish a supraatmosferica pressure throughout the respiratory cycle on which the patient vent spontaneously. Its use improves the clinical and gasometrics parameters when applied with appropriate selection criteria in the context of respiratory failure acute (IRA) hypoxemic. It has been demonstrated that applying CPAP early, decreases the need for intubation and associated complications, as well as survival, reducing health care costs and hospital stay. The use of valve Boussignac for applying a CPAP is spreading especially in the delivered environment and emergencies as a device not mechanical, simple, easy to use and transport, which can manage enough pressures to manage the patient hypoxemia...

BACKGROUND: Spinal intradural arachnoid cysts are rare with only a few patients reported so far. Idiopathic, traumatic, posthemorrhagic, and postinflammatory causes have been reported in the literature. Especially, idiopathic lesions, in which other possible etiological factors have been ruled out, seem to be rare. PATIENTS AND METHODS: We systematically reviewed the literature in regards to localization within the spinal canal, treatment options, complications, and outcome...

Recent evidence of the significant impact of gastroparesis on morbidity and mortality mandates optimized management of this condition. Gastroparesis affects nutritional state, and in diabetics it has deleterious effects on glycemic control and secondary effects on organs that increase mortality. First-line treatments include restoration of nutrition and medications (prokinetic and antiemetic). We review the epidemiology, pathophysiology, impact, natural history, time trends, and treatment of gastroparesis, focusing on diabetic gastroparesis...

Contradictions between system-specific evidence and broader paradigms to explain ecosystem behavior present a challenge for natural resource management. In Florida (U.S.A.) springs, increasing nitrate (NO3-) concentrations have been implicated as the cause of algal overgrowth via alleviation of N-limitation. As such, policy and management efforts have centered heavily on reduction of nitrogen (N) loads. While the N-limitation hypothesis appears well founded on broadly supported aquatic eutrophication models, several observations from Florida springs are inconsistent with this hypothesis in its present simplified form...

Head injuries are a major cause of morbidity and mortality worldwide, many resulting from sporting activities. There is a constant need in the head protection industry for improved methods to manage impacts and to reduce the risk of mild and severe head injuries. Contemporary head protection primarily consists of foam with several inherent disadvantages, including a limited ability to provide effective energy absorption under both low and high impact velocities. Recently, thin-walled collapsible chambers were engineered to address this problem and have been implemented into sport helmets...

Activation of the innate immune system results from severe trauma and the resultant systemic inflammatory response is thought to mediate remote organ injury. In animal models, vagal-mediated innate immune responses have been shown to modulate proinflammatory cytokine release in response to trauma or sepsis. In those models, vagal nerve transaction and splenectomy decreased cytokine release and protected against lung injury and mortality. We hypothesized that, if similar mechanisms are active in humans, patients who require splenectomy for trauma would have better outcomes than injured patients without splenectomy...

To mimic airborne immune challenges, layer hens were intratracheally and concurrently challenged with various doses of the protein antigen human serum albumin (HuSA) and the pathogen-associated molecular pattern lipopolysaccharide (LPS) at 7 and 13 wk of age. All groups received 1 similar dose of HuSA plus LPS at 11 mo of age. Evaluation of plumage and body condition at 12 mo of age revealed that birds that had undergone intratracheal immunization with a high dosage of HuSA, irrespective of the concurrent dose of LPS, had significantly more feather damage but less wounds to the vent region, as opposed to birds not receiving HuSA...

Sediment contamination is a significant issue. Assessment, management, and monitoring of contaminated sediment require routine analyses of a large volume of sediment samples, which require significant preparation time including extraction of contaminants from samples prior to analysis. This work tested a new method of extracting contaminants from sediment based on the use of rapid, successive pressurization cycles, which involve compression of a gas into the extractive solvent in contact with the sediment immediately followed by decompression via venting...

Multidrug-resistant Acinetobacter baumannii resistant to carbapenems (MRAB-C) has become endemic in many hospitals in the UK. We describe an outbreak of MRAB-C that occurred on two intensive care units using ORION criteria (Outbreak Reports and Intervention studies Of Nosocomial infection). All patients colonised or infected with MRAB-C were included. Enhanced infection control precautions were introduced in Phase 1 of the outbreak. The adult neurosciences critical care unit (NCCU) was partially closed in Phase 2 and strict patient segregation, barrier nursing and screening thrice weekly was introduced...

BACKGROUND: The conventional standard of care for many patients at Saint Joseph HealthCare, a three-hospital system in Kentucky, includes the use of anticoagulant therapy. In view of the morbidity and mortality associated with anticoagulation-related complications, the prevention of bleeding and thrombotic adverse drug events was identified as a primary process improvement initiative. METHODS: Following establishment of an interdisciplinary team, formal evaluations of anticoagulant-use practices and associated patient outcomes occurred via several mechanisms...

Relief ducts fitted to venting openings is a widespread configuration in the industrial practice. The presence of a duct has been reported to severely increase the violence of the vented explosion posing a problem for the proper design of the venting device. Several studies have reported the leading importance--in the whole complex explosion phenomenology--of a secondary explosion in the duct. Modern approaches in the study of simply vented explosions (without ducts) have focused on the study of the interaction between internal and external explosion as a key issue in the mechanisms of pressure generation...

Due to initiatives such as the clean development mechanism (CDM), reducing greenhouse gas emissions for a developing country can offer an important route to attracting investment in a variety of qualifying project areas, including waste management. To date CDM projects have been largely confined to schemes that control emission from landfill, but projects that avoid landfilling are beginning to be submitted. In considering the waste options which might be suitable for developing countries certain ones, such as energy from waste, have been discounted for a range of reasons related primarily to the lack of technical and other support services required for these more sophisticated process trains...

The authors report a new technique of pulley plasty of the flexor digital system. It is not an operative procedure to reconstruct a damaged pulley but an original way to expand the volume of an intact pulley in order to adapt its volume to the diameter of the repaired flexor tendon. The flexor tendons ruptures in Verdan zone II and particularly in Tang zones IIA and IIB are often accompanied by an osteofibrous tunnel injury. Initially, the tendon sheath closure was advised after tendons repair. This sheath recovery had to have an effect on tendons nutrition by establishing the synovial cavity continuity and particularly to protect the tendons from adhesions formation...

The first bridge to transplant with a left ventricular assist device (LVAD) was preformed over 20 years ago. Since that time, the devices have continued to evolve and now patients are being supported with devices as an alternative to transplantation. The primary indication of end-stage heart failure remains the same but increased knowledge about patient selection, the timing of implant, and patient management have contributed to improved outcomes with decreasing adverse events. Multiorgan failure, right ventricular failure, bleeding, infection, thromboembolism, and device malfunction continue to be the most serious threats to long-term survival in these patients...

This article reviews infections that occur in patients with implanted mechanical circulatory support devices and presents recent data for signs of progress in controlling the incidence and impact of these infections. Two types of comparisons are used to examine this question. First, the outcomes of patients with HeartMate vented electric left ventricular assist devices (VADs) (Thoratec Corp, Pleasanton, CA) implanted during the REMATCH Trial are compared with the outcome of more recent patients who received this pump as destination therapy...

BACKGROUND AND AIMS: Irritable bowel syndrome (IBS) is defined by specific validated symptom criteria and encompasses several different underlying pathophysiological mechanisms that express a common set of symptoms. However, IBS is poorly understood by patients. We aimed to explore how a diagnosis of IBS affects the interaction between patients and their physicians. METHODS: A comprehensive literature search for studies in the English language addressing this issue was conducted using Medline, PubMed, Cochrane Database, Psychinfo, Cinahl, Embase, Web of Science and manual recursive search of reference lists...
