Feasibility, Contrast Sensitivity and Network Specificity of Language fMRI in Presurgical Evaluation for Epilepsy and Brain Tumor Surgery.

Brain Topogr 2021 Apr 10. Epub 2021 Apr 10.

Department of Medicine, School of Health Sciences, Democritus University of Thrace, Xanthi, Greece.

Language fMRI has become an integral part of the planning process in brain surgery. However, fMRI may suffer from confounding factors both on the patient side, as well as on the provider side. In this study, we investigate how patient-related confounds affect the ability of the patient to perform language fMRI tasks (feasibility), the task sensitivity from an image contrast point of view, and the anatomical specificity of expressive and receptive language fMRI protocols.

NarxCare Scores Greater Than 300 Are Associated with Adverse Outcomes After Primary THA.

Clin Orthop Relat Res 2021 Apr 7. Epub 2021 Apr 7.

A. K. Emara, D. Grits, A. K. Klika, R. M. Molloy, V. E. Krebs, W. K. Barsoum, C. Higuera-Rueda, N. S. Piuzzi, Department of Orthopaedic Surgery, Cleveland Clinic Foundation, Cleveland, OH, USA.

Background: The association between preoperative prescription drug use (narcotics, sedatives, and stimulants) and complications and/or greater healthcare utilization (length of stay, discharge disposition, readmission, emergency department visits, and reoperation) after total joint arthroplasty has been established but not well quantified. The NarxCare score (NCS) is a weighted scalar measure of overall prescription opioid, sedative, and stimulant use. Higher scores reflect riskier drug-use patterns, which are calculated based on (1) the number of prescribing providers, (2) the number of dispensing pharmacies, (3) milligram equivalence doses, (4) coprescribed potentiating drugs, and (5) overlapping prescription days.

Nicotinamide Mononucleotide Attenuates Renal Interstitial Fibrosis After AKI by Suppressing Tubular DNA Damage and Senescence.

Front Physiol 2021 23;12:649547. Epub 2021 Mar 23.

Key Laboratory of Renal Disease, Renal Division, Department of Medicine, Peking University First Hospital, Peking University Institute of Nephrology, Ministry of Health of China, Beijing, China.

Acute kidney injury (AKI) is a worldwide health problem currently lacking therapeutics that directly promote renal repair or prevent the occurrence of chronic fibrosis. DNA damage is a feature of many forms of kidney injury, and targeting DNA damage and repair might be effective strategies for kidney protection in AKI. Boosting nicotinamide adenine dinucleotide (NAD) levels is thought to have beneficial effects on DNA damage repair and fibrosis in other organs. Read More

[Ground reaction forces during gait in people with unilateral transtibial amputation, a series of cases].

Rehabilitacion (Madr) 2021 Apr 5. Epub 2021 Apr 5.

Universidad Autónoma de Manizales, Manizales, Colombia.

Unilateral Transtibial Amputees (UTA) usually present deficiencies in the mechanisms underlying their gait likely because of the absence of the resected segment, thus having an impact on the ability to actively adjust the lower limb prosthesis. Five participants with UTA were evaluated considering the ground reaction forces during gait by using an integrated BTS GAITLAB system. The first and the second vertical peak forces tended to be greater in the Healthy Lower Limb (HLL) than in the Lower Limb prosthesis (LLP). Read More

Handb Clin Neurol 2021 ;178:257-275

Departments of Medicine (Neurology), Ophthalmology and Visual Sciences, and Psychology, University of British Columbia, Vancouver, BC, Canada. Electronic address:

As we live in a dynamic world, motion is a fundamental aspect of our visual experience. The advent of computerized stimuli has allowed controlled study of a wide array of motion phenomena, including global integration and segmentation, speed and direction discrimination, motion aftereffects, the optic flow that accompanies self-motion, perception of object form derived from motion cues, and point-light biological motion. Animal studies first revealed the existence of a motion-selective region, the middle temporal (MT) area, also known as V5, located in the lateral occipitotemporal cortex, followed by areas such as V5A (also known as MST, the middle superior temporal area), V6/V6A, the ventral intraparietal area, and others.
