Assessing Sleep Architecture With Polysomnography During Posttraumatic Amnesia After Traumatic Brain Injury: A Pilot Study.

Neurorehabil Neural Repair 2021 May 12:15459683211011241. Epub 2021 May 12.

Epworth HealthCare, Melbourne, Victoria, Australia.

Background: Early-onset sleep disturbance is common following moderate to severe traumatic brain injury (TBI) and often emerges while patients are in posttraumatic amnesia (PTA). However, sleep disruptions during this subacute recovery phase are not well-defined, and research often utilizes indirect measures (actigraphy) that quantify sleep based on activity. This study aims to examine sleep macro-architecture and sleep quality directly with ambulatory polysomnography (PSG) and measure endogenous salivary melatonin levels for patients experiencing PTA following moderate to severe TBI.

Rates of false positive outcomes on the A-WPTAS picture items in a sample of non-concussed athletes.

Brain Inj 2021 Jun 10;35(7):783-787. Epub 2021 May 10.

Department of Cognitive Science, Macquarie University, Sydney, NSW, Australia.

Accurate diagnosis of sports related concussion ensures that athletes are removed from play if concussed and prevents incorrect removal when a concussion has not occurred. Although various screening tools are currently in use, there is no gold standard measure with which to diagnose sports related concussion.: The current study aimed to investigate the diagnostic accuracy of the Abbreviated Westmead Post Traumatic Amnesia Scale (A-WPTAS) picture task, a neurocognitive measure used to assess mild traumatic brain injury.

Population Pharmacokinetic Modeling and Simulations of Imipenem in Burn Patients With and Without Continuous Venovenous Hemofiltration in the Military Health System.

J Clin Pharmacol 2021 Apr 2. Epub 2021 Apr 2.

Walter Reed Army Institute of Research, Experimental Therapeutics, Silver Spring, Maryland, USA.

Continuous venovenous hemofiltration (CVVH) is a life-sustaining procedure in patients with severe burns and acute kidney injury.

Popliteal artery: Anatomical study and review of the literature.

Ann Anat 2021 Mar 2;234:151654. Epub 2020 Dec 2.

Department of Human Anatomy and Embryology, Facultad de Medicina, Universidad Complutense de Madrid, Spain. Electronic address:

Background: The frequency of appearance of anatomical variability in the terminal division of the popliteal artery (PA) is different according to the type of sample used, and ranges from 2% to 21%. The PA locates 1,01 cm behind to the lateral meniscus, which makes it vulnerable during surgical procedures. Iatrogenic injury of the PA or its terminal branches increases if anatomical variables are present. Read More

J Dairy Sci 2021 Feb 25;104(2):2357-2368. Epub 2020 Nov 25.

Department of Animal Sciences, University of Florida, Gainesville, 32608. Electronic address:

Multiparous, nonlactating pregnant cows are negatively affected by heat stress, but the effect of heat stress on more thermotolerant pregnant heifers has received less attention. Our objective was to characterize the effect of late-gestation heat abatement on thermoregulatory responses and subsequent milk production of nulliparous Holstein heifers. Pregnant heifers, blocked by body condition score (BCS) and predicted transmitting ability (PTA) for milk, were enrolled in either heat stress (HT, shade of freestall barn; n = 16) or cooling (CL, shade of freestall barn, water soakers, and fans; n = 15) environments during the last 60 d of pregnancy (~8 weeks).

The accuracy of a novel pedicle screw insertion technique assisted by a special angular scale in the subaxial cervical spine using lateral mass as a reference marker.

J Orthop Surg Res 2020 Nov 23;15(1):551. Epub 2020 Nov 23.

Department of Spine Surgery, Zhongda Hospital, School of Medicine, Southeast University, Nanjing, 210009, Jiangsu, China.

Background: Posterior cervical pedicle screw (CPS) internal fixation has better biomechanical stability than other posterior cervical fixation methods. However, this technique is limited in clinical practice due to the complex anatomical structure and the adjacent relationship of the cervical pedicle, and the high risk of neurovascular injury. The purpose of this study was to describe a novel subaxial CPS insertion technique assisted by a special angular scale using lateral mass as a reference marker and to evaluate the accuracy of CPS placement and the distribution characteristics of CPS misplacement.

Initial displacement of the intra-articular surface after articular fracture correlates with PTA in C57BL/6 mice but not "superhealer" MRL/MpJ mice.

J Orthop Res 2020 Nov 12. Epub 2020 Nov 12.

Department of Orthopaedic Surgery, Duke University Medical Center, Durham, North Carolina, USA.

Posttraumatic arthritis (PTA) occurs commonly after articular fracture and may arise, in part, from joint surface incongruity after injury. MRL/MpJ (MRL) "super-healer" mice are protected from PTA compared to C57BL/6 (B6) mice following articular fracture. However, the relationship between the initial displacement of the articular surface, biologic response, and susceptibility to PTA after fracture remains unclear. Read More

Turner Institute for Brain and Mental Health, School of Psychological Sciences, Monash University, Clayton, Victoria, Australia.

Most individuals with traumatic brain injury (TBI) experience a period of confusion after emergence from coma, termed post-traumatic amnesia, post-traumatic confusional state, or delirium. Recent guidelines suggest the importance of assessment and consistent management during this phase, but current practice worldwide remains unknown. This survey aimed to elucidate current international practice in assessment and treatment of patients in the acute stages of recovery after TBI. Read More

Traumatic axonal injury on clinical MRI: association with the Glasgow Coma Scale score at scene of injury or at admission and prolonged posttraumatic amnesia.

J Neurosurg 2020 Oct 23:1-12. Epub 2020 Oct 23.

Departments of1Neuromedicine and Movement Science and.

Objective: The aim in this study was to investigate if MRI findings of traumatic axonal injury (TAI) after traumatic brain injury (TBI) are related to the admission Glasgow Coma Scale (GCS) score and prolonged duration of posttraumatic amnesia (PTA).

Methods: A total of 490 patients with mild to severe TBI underwent brain MRI within 6 weeks of injury (mild TBI: median 2 days; moderate to severe TBI: median 8 days). The location of TAI lesions and measures of total TAI lesion burden (number and volume of lesions on FLAIR and diffusion-weighted imaging and number of lesions on T2*-weighted gradient echo or susceptibility-weighted imaging) were quantified in a blinded manner for clinical information.

Cleaning Up the MESS: Can Machine Learning Be Used to Predict Lower Extremity Amputation after Trauma-Associated Arterial Injury?

J Am Coll Surg 2021 Jan 3;232(1):102-113.e4. Epub 2020 Oct 3.

Department of Surgery, Donald and Barbara Zucker School of Medicine at Hofstra/Northwell, Manhasset, NY; Divisions of Vascular and Endovascular Surgery, Donald and Barbara Zucker School of Medicine at Hofstra/Northwell, Manhasset, NY. Electronic address:

Background: Thirty years after the Mangled Extremity Severity Score was developed, advances in vascular, trauma, and orthopaedic surgery have rendered the sensitivity of this score obsolete. A significant number of patients receive amputation during subsequent admissions, which are often missed in the analysis of amputation at the index admission. We aimed to identify risk factors for and predict amputation on initial admission or within 30 days of discharge (peritraumatic amputation [PTA]). Read More

Two Coarse Spatial Patterns of Altered Brain Microstructure Predict Post-traumatic Amnesia in the Subacute Stage of Severe Traumatic Brain Injury.

Front Neurol 2020 4;11:800. Epub 2020 Sep 4.

Danish Research Centre for Magnetic Resonance (DRCMR), Centre for Functional and Diagnostic Imaging Research, Copenhagen University Hospital Hvidovre, Hvidovre, Denmark.

Diffuse traumatic axonal injury (TAI) is one of the key mechanisms leading to impaired consciousness after severe traumatic brain injury (TBI). In addition, preferential regional expression of TAI in the brain may also influence clinical outcome. We addressed the question whether the regional expression of microstructural changes as revealed by whole-brain diffusion tensor imaging (DTI) in the subacute stage after severe TBI may predict the duration of post-traumatic amnesia (PTA).
