Magnetic graphene derivates for efficient herbicide removal from aqueous solution through adsorption.

2,4-Dichlorophenoxyacetic acid (2,4-D) is an herbicide and is among the most widely distributed pollutant in the environment and wastewater. Herein is presented a complete comparison of adsorption performance between two different magnetic carbon nanomaterials: graphene oxide (GO) and its reduced form (rGO). Magnetic functionalization was performed employing a coprecipitation method, using only one source of Fe, requiring low energy, and potentially allowing the control of the amount of incorporated magnetite.

Nurses' stress and resilience before and after evaluation for hospital accreditation.

Objectives: to analyze and compare levels of stress and resilience in nurses before and after the assessment for maintenance of the Hospital Accreditation Certification.

Bromoderma in an infant.

Bromoderma is a cutaneous eruption caused by the absorption of bromide. Clinical manifestations include acneiform and vegetative lesions. We report the case of an infant with bromoderma caused by the use of syrup for abdominal colic containing calcium bromide.

Acute generalized exanthematous pustulosis associated with spider bite.

Acute generalized exanthematous pustulosis (AGEP) is an acute febrile rash, usually induced by drugs, which recently has been linked to spider bite. We report a case of a male patient, 48 years old, with an erythematous rash accompanied by fever and small non-follicular pustules. He reported previous pain in the buttock with the onset of a necrotic plaque.

Endoscopic basilic vein transposition for hemodialysis access.

Background: Hemodialysis access by autogenous arteriovenous fistulas (AVFs) is generally recommended due to lower mortality, morbidity, and cost vs graft and catheter use. Many dialysis patients lack the common superficial veins used for standard AVF options and require transposition of a deep vein for autogenous dialysis access through a long open incision (open/AVF-T). These operations may require prolonged time for healing, thus extending catheter-based dialysis.

Peritoneal dialysis catheters: laparoscopic versus traditional placement techniques and outcomes.

Background: Peritoneal dialysis is used for renal replacement therapy in over 25,000 patients in the United States. Some authors have recommended laparoscopic guidance for peritoneal dialysis catheter (PDC) placement, although consensus statements have not favored a specific technique. This study reviews outcomes in patients in whom placement was performed by the traditional "blind" technique (B-PDC) versus the laparoscopic technique (L-PDC).

Laparoscopic Heller myotomy for achalasia.

Background: Achalasia is an uncommon illness affecting 1 per 100,000 patients yearly. There is evidence to suggest viral, autoimmune, and hereditary etiologies. There are many treatment options available including medications, botulinum toxin injection, pneumatic dilation, and surgical myotomy.

Techniques for repair of gastric prolapse after laparoscopic gastric banding.

Laparoscopic gastric banding is a valuable surgical option for treating morbidly obese patients. Its operative technique is continually being refined. Since its inception, many changes in technique have helped to reduce the complication rate.

Immune-enhancing enteral diet selectively augments ileal blood flow in the rat.

Background: Clinical studies show that immune-enhancing enteral diets (IED; with L-arginine, fish oil, and RNA fragments) decrease the rate of sepsis and shorten the length of hospital stay after the start of enteral feeding. These beneficial effects are dependent on the route of administration (enteral vs parenteral) and on the nutrient composition (IED vs standard diets). Gut exposure to an IED seems to preserve and/or augment intestinal mucosal immunity.

The source of coagulase-negative staphylococci in the Endophthalmitis Vitrectomy Study. A comparison of eyelid and intraocular isolates using pulsed-field gel electrophoresis.

Objective: To determine the species distribution of coagulase-negative staphylococci (CoNS) in patients with endophthalmitis and to ascertain whether the patient's own flora was a major source of postoperative endophthalmitis following cataract extraction.

Methods: In a 4-year multicenter prospective study, 524 bacterial isolates were submitted from 225 Endophthalmitis Vitrectomy Study patients. From the 524 isolates, 250 represented CoNS cultured from the anterior chamber, the vitreous, or both of the 225 patients.

Abnormalities in lymphocyte populations in infants with neural crest cardiovascular defects.

The DiGeorge syndrome has been associated with various immune deficits. Embryologically, defects of the neural crest are associated with conotruncal and aortic arch abnormalities. The objective of this study was to determine if children with neural crest congenital heart defects can have subtle but significant immunodeficiencies.

Four-year prospective study of STAPH-IDENT system and conventional method for reference identification of Staphylococcus, Stomatococcus, and Micrococcus spp.

A 4-year prospective study compared the accuracy of the STAPH-IDENT system (bioMérieux Vitek, Inc., Hazelwood, Mo.) with that of the reference procedure of the Centers for Disease Control and Prevention for the identification of Staphylococcus species, Stomatococcus mucilaginosus, and Micrococcus species.

Symptomatic vitamin A and D deficiencies in an eight-year-old with autism.

An 8-year-old boy with autism developed a limp and periorbital swelling. He was found to have hypocalcemia and radiographic evidence of rickets. Ophthalmologic examination revealed xerophthalmia and corneal erosions.

Numerical approach to reference identification of Staphylococcus, Stomatococcus, and Micrococcus spp.

A numerical-code system for the reference identification of Staphylococcus species, Stomatococcus mucilaginosus, and Micrococcus species was established by using a selected panel of conventional biochemicals. Results from 824 cultures (289 eye isolate cultures, 147 reference strains, and 388 known control strains) were used to generate a list of 354 identification code numbers. Each six-digit code number was based on results from 18 conventional biochemical reactions.

Prevalence of serotypes of Xanthomonas maltophilia from world-wide sources.

Since its development in 1988, a serologic typing scheme for Xanthomonas maltophilia, based on 31 O antigens, has been successfully used to serotype isolates involved in nosocomial outbreaks in the United States. To determine if this serotyping scheme would be useful in typing X. maltophilia isolates from world-wide sources, we obtained additional isolates from 10 countries; of 900 isolates tested, 795 (88.

Reevaluation of the API 20E identification system versus conventional biochemicals for identification of members of the family Enterobacteriaceae: a new look at an old product.

The API 20E bacterial identification system has been used for 19 years, often as the standard with which other identification systems are compared. Because the accuracy of this system compared with conventional biochemical tests has not been determined in many years, we evaluated the API 20E linear strip by using 291 typical and atypical strains of the family Enterobacteriaceae taken from a culture collection. At 24 h, the API 20E correctly identified by genus and species 229 of 291 (78.

Comparison of the autoSCAN-W/A rapid bacterial identification system and the Vitek AutoMicrobic system for identification of gram-negative bacilli.

The autoSCAN-W/A (W/A; Baxter MicroScan, West Sacramento, Calif.) with the new fluorometric Rapid Neg Combo 1 (RNC) panel is a fully automated fluorometric system for identification of both enteric and nonenteric gram-negative bacilli within 2 h. We compared the W/A with the Vitek AutoMicrobic System (Vitek AMS; Vitek Systems, Inc.

Preliminary evaluation of Biolog, a carbon source utilization method for bacterial identification.

The Biolog Identification System (Biolog, Inc., Hayward, Calif.) is a new bacterial identification method that establishes an identification based on the exchange of electrons generated during respiration, leading to a subsequent tetrazolium-based color change.

Agreement between visual and automated UniScept API readings.

The UniScept API system was evaluated for agreement of visual versus automated readings of both its identification panels and its antimicrobial susceptibility panels.
