Wrapping double-mattress anastomosis for pancreaticojejunostomy in minimally invasive pancreaticoduodenectomy can significantly reduce postoperative pancreatic fistula rate compared with conventional pancreaticojejunostomy in open surgery: An analysis of a propensity score-matched sample.

Surg Oncol 2021 Apr 9;38:101577. Epub 2021 Apr 9.

Department of Surgery, Fujita Health University, 1-98 Dengakugakubo, Kutsukake-cho, Toyoake, Aichi, 470-1192, Japan.

Over half of clinical practice guidelines use non-systematic methods to inform recommendations: A methods study.

PLoS One 2021 22;16(4):e0250356. Epub 2021 Apr 22.

Department of Anesthesiology, Pharmacology & Therapeutics, Faculty of Medicine, Cochrane Hypertension Review Group, Therapeutics Initiative, University of British Columbia, Vancouver, BC, Canada.

Introduction: Assessing the process used to synthesize the evidence in clinical practice guidelines enables users to determine the trustworthiness of the recommendations. Clinicians are increasingly dependent on guidelines to keep up with vast quantities of medical literature, and guidelines are followed to avoid malpractice suits. We aimed to assess whether systematic methods were used when synthesizing the evidence for guidelines; and to determine the type of review cited in support of recommendations. Read More

Intraoperative Seizure Detection During Active Resection of Glioblastoma Through a Novel Hollow Circular Electrocorticography Array.

Oper Neurosurg (Hagerstown) 2021 Apr 22. Epub 2021 Apr 22.

Department of Neurology, Mayo Clinic, Jacksonville, Florida, USA.

Background And Importance: Data supporting the use of electrocorticography (ECoG) monitoring during electrical stimulation in awake craniotomies for resection of supratentorial neoplasms is robust, but its applicability during active resection is often limited by the inability to keep the array in place. Given the known survival benefit of gross total resection in glioma surgery, novel approaches to surgical monitoring are warranted to maximize safe resection and optimize surgical outcomes in patients with glioblastoma.

Clinical Presentation: A 68-yr-old right-handed woman presented to the emergency department with confusion. Read More

Radiological evaluation of ex novo high grade glioma: velocity of diametric expansion and acceleration time study.

Radiol Oncol 2020 Dec 3;55(1):26-34. Epub 2020 Dec 3.

Division of Neurosurgery, Department of Neurosciences, Policlinico "G. Rodolico", University Hospital, Catania, Italy.

Background: One of the greatest neuro-oncological concern remains the lack of knowledge about the etiopathogenesis and physiopathology of gliomas. Several studies reported a strict correlation between radiological features and biological behaviour of gliomas; in this way the velocity of diametric expansion (VDE) correlate with lower grade glioma aggressiveness. However, there are no the same strong evidences for high grade gliomas (HGG) because of the lack of several preoperative MRI. Read More

Development of zein/soluble soybean polysaccharide nanoparticle-stabilized Pickering emulsions.

J Food Sci 2021 Apr 22. Epub 2021 Apr 22.

Key Laboratory of Fermentation Engineering, Ministry of Education, National "111" Center for Cellular Regulation and Molecular Pharmaceutics, Hubei Key Laboratory of Industrial Microbiology, School of Biological Engineering and Food, Hubei University of Technology, Wuhan, China.

Pickering emulsions have received wide attention due to their "surfactant-free" character and the ability of delivery bioactive compounds. In the current work, zein and soluble soybean polysaccharide (SSPS) food-grade composite nanoparticles (NPs) were fabricated as Pickering stabilizers. The particle size of the composite NPs varied with the concentration of zein and SSPS, consequently leading to larger hydrodynamic diameters compared with zein nanoparticles (ZPs) in all formulations, also seen from the scanning electron microscopy (SEM) images.

Day care as a strategy for drowning prevention in children under 6 years of age in low- and middle-income countries.

Cochrane Database Syst Rev 2021 Apr 22;4:CD014955. Epub 2021 Apr 22.

Department of Public Health and Primary Care, Faculty of Medicine, KU Leuven, Leuven, Belgium.

Background: Drowning is responsible for an estimated 320,000 deaths a year, and over 90% of drowning mortality occurs in low- to middle-income countries (LMICs), with peak drowning rates among children aged 1 to 4 years. In this age group, mortality due to drowning is particularly common in rural settings and about 75% of drowning accidents happen in natural bodies of water close to the home. Providing adequate child supervision can protect children from drowning, and organized formal day care programs could offer a way to achieve this. Read More
