Tracking Arteriovenous Fistula Maturation: A Novel Approach.

Blood Purif 2018 Dec 6:1-6. Epub 2018 Dec 6.

Renal Research Institute, New York, New York, USA.

Background: The time between the creation of an arteriovenous fistula (AVF) and its successful use is significantly longer in hemodialysis (HD) patients in the United States compared to those in other countries, and there is an urgent need to reduce the residence time of central-venous catheters (CVC).

Methods: Successful AVF creation and maturation results in typical hemodynamic changes, such as an increase in cardiac output and upper body blood flow (UBBF). In patients with CVC as vascular access, we measured once per minute intradialytic central-venous oxygen saturation (ScvO2) and hemoglobin levels simultaneously using the Crit-Line Monitor.

Association of Central Venous Oxygen Saturation Variability and Mortality in Hemodialysis Patients.

Blood Purif 2018 Dec 6:1-8. Epub 2018 Dec 6.

Renal Research Institute, New York, New York,

Background: Central venous oxygen saturation (ScvO2) is correlated with cardiac output. In most patients, ScvO2 declines during hemodialysis (HD) due to factors such as reduced preload, myocardial stunning, and intermittent arrhythmias. Previous research has shown that low ScvO2 is associated with higher mortality in chronic HD patients. Read More

Temporal fluctuations in young-of-the-year yellow perch mercury bioaccumulation in lakes of northeastern Minnesota.

Sci Total Environ 2018 Nov 22;656:475-481. Epub 2018 Nov 22.

USDA Forest Service, Superior National Forest, 8901 Grand Ave Place, Duluth, MN 55808, USA. Electronic address:

Identifying what determines fish mercury (Hg) bioaccumulation remains a key scientific challenge. While there has been substantial research on spatial variation in fish Hg bioaccumulation, the factors that influence temporal fluctuations in fish Hg have received less attention to date. In this study, we built upon a growing body of research investigating young-of-the-year (YOY) yellow perch Hg bioaccumulation and investigated annual fluctuations in YOY yellow perch Hg in six lakes in northeastern Minnesota over eight years.

The impact of dam flushing event on dissolved trace elements concentrations: Coupling integrative passive sampling and discrete monitoring.

Sci Total Environ 2018 Nov 22;656:433-446. Epub 2018 Nov 22.

Irstea, UR RiverLy, centre de Lyon-Villeurbanne, 5 rue de la Doua, CS 20244, F-69625, Villeurbanne Cedex, France.

Sediments accumulation in reservoirs induces water storage capacities reduction and flood risks increases rendering dam flushing or dredging events compulsory for security reasons. Short transient events like dam flushing monitoring is still a great challenge because the suspended sediments and contaminants concentrations increases could occur over only few hours/days and cover tens of kilometres. Since 1942, 21 dam flushing events have been performed on the Upper Rhône River (from Lake Geneva in Switzerland to Lyon in France) in order to evacuate accumulated sediments behind the Verbois dam (Switzerland).

Posterior Extensive Circumferential Decompressive Reconstructive Technique in surgical treatment of Upper Thoracic Spine Compressive Lesions.

World Neurosurg 2018 Dec 3. Epub 2018 Dec 3.

Department of Orthopedic Surgery and Traumatology and Minia University Hospital, Mohammed Badway str., 61111, El-Minia, Egypt; Minia University Spine Unit (MUSU), Faculty of Medicine, Minia University. Minia University Hospital, Mohammed Badway str., 61111, El-Minia, Egypt. Electronic address:

Background Data: Complexity in ventral surgical exposure, presence of scapula and large para-scapular musculature during posterior surgery are the main obstacles in operative treatment of Upper Thoracic Spine Compressive Lesions (UTSCL) like trauma, tuberculosis and neoplasm. Recently, the advantages of combined ventro-dorsal surgery could be successfully gained using 1-stage posterior salvage technique with enough accessibility to all three spinal columns.

Purpose: Retrospective evaluation of 35 patients with UTSCL treated by Posterior Extensive Circumferential Decompressive Reconstructive (PECDR) procedure. Read More

Locomotor central pattern generator excitability states and serotonin sensitivity after spontaneous recovery from a neonatal lumbar spinal cord injury.

Brain Res 2018 Dec 3. Epub 2018 Dec 3.

Norwegian Center for Stem Cell Research, Oslo University Hospital, Norway. Electronic address:

The spinal locomotor central pattern generator (CPG) in neonatal mice exhibits diverse output patterns, ranging from sub-rhythmic to multi-rhythmic to fictive locomotion, depending on its general level of excitation and neuromodulatory status (Sharples and Whelan, 2017). We have recently reported that the locomotor CPG in neonatal mice rapidly recovers the ability to produce neurochemically induced fictive locomotion following an upper lumbar spinal cord compression injury (Züchner et al., 2018).

Departamento de Piel y Partes Blandas del Instituto Nacional de Cancerología. Ciudad de México, México.

Dedifferentiated parosteal osteosarcoma is a variant in which a high grade osteosarcoma coexists with a parosteal osteosarcoma. We report the case of a 20-year-old female patient who presented with six months of evolution of pain and functional limitation of the right forearm, with no apparent cause; radiographs were performed, observing a tumoral lesion in the diaphysis of the right ulna.

Reflectance confocal microscopy for diagnosing keratinocyte skin cancers in adults.

Cochrane Database Syst Rev 2018 Dec 3;12:CD013191. Epub 2018 Dec 3.

Institute of Applied Health Research, University of Birmingham, Birmingham, UK, B15 2TT.

Background: Early accurate detection of all skin cancer types is important to guide appropriate management and improve morbidity and survival. Basal cell carcinoma (BCC) is usually a localised skin cancer but with potential to infiltrate and damage surrounding tissue, whereas cutaneous squamous cell carcinoma (cSCC) and melanoma are higher risk skin cancers with the potential to metastasise and ultimately lead to death. When used in conjunction with clinical or dermoscopic suspicion of malignancy, or both, reflectance confocal microscopy (RCM) may help to identify cancers eligible for non-surgical treatment without the need for a diagnostic biopsy, particularly in people with suspected BCC.

Pain could negatively affect school grades - Swedish middle school students with low school grades most affected.

PLoS One 2018 6;13(12):e0208435. Epub 2018 Dec 6.

Occupational and environmental medicine, Public Health and Community Medicine, Sahlgrenska Academy, University of Gothenburg, Gothenburg, Sweden.

Recurrent headache, abdominal and musculoskeletal pain are common in adolescents and it is therefore important to understand their impact on the transitional period from childhood to adulthood. However, studies of the prevalence over time and implications on educational outcomes are still limited, especially regarding multiple pain symptoms. The present study material consists of questionnaire surveys, completed in 2000 and 2008, including two study populations of 9th grade adolescents aged 15 living in West Sweden (n = 20 877).

Intracerebroventricular administration of sulfated CCK octapeptide induces anxiety-like behavior in goldfish.

J Neuroendocrinol 2018 Dec 6:e12667. Epub 2018 Dec 6.

Laboratory of Regulatory Biology, Graduate School of Science and Engineering, University of Toyama, Toyama, 930-8555, Japan.

Sulfated cholecystokinin octapeptide (CCK-8s) is involved in feeding regulation as an anorexigenic neuropeptide in vertebrates. In rodents, intracerebroventricular (ICV) administration of CCK-8s has been shown to affect not only feeding behavior, but also psychomotor activity. However, there is still no information regarding the psychophysiological effects of CCK-8s in goldfish. Read More
