Conducting Research With Older Adults With Vision Impairment: Lessons Learned and Recommended Best Practices.

Gerontol Geriatr Med 2018 Jan-Dec;4:2333721418812624. Epub 2018 Nov 28.

University of Utah, Salt Lake City, USA.

Older adults are underrepresented in research, and a potential barrier to their participation may be the increasing prevalence of vision loss and lack of accommodation for this challenge. Although vision loss may initially pose a challenge to research participation, its effects can be mitigated with early, in-depth planning. For example, recruitment is more inclusive when best practices identified in the literature are used in the preparation of written materials to reduce glare and improve readability and legibility.

Three-Dimensional Templating and Use of Standard Instrumentation in Primary Anatomic Total Shoulder Arthroplasty.

JBJS Essent Surg Tech 2017 Sep 27;7(3):e28. Epub 2017 Sep 27.

Orthopaedic and Rheumatologic Institute, Cleveland Clinic, Cleveland, Ohio.

Introduction: Three-dimensional (3D) templating of the glenoid in anatomic shoulder arthroplasty allows for more accurate planning and more optimal positioning of the glenoid component than 2-dimensional computed tomography (2D CT) scans through an improved understanding of both the pathologic and the premorbid glenoid joint line, version, and inclination in reference to an idealized calculated glenoid position.

Indications & Contraindications:

Step 1 Obtain A Ct Scan With 3d Reconstruction And Define Glenoid Version And Inclination: Obtain a CT scan of the entire scapula and proximal part of the humerus with slices of ≤1 mm and a 3D reconstruction with subtraction of the humeral head, and identify the scapular and glenoid planes to define the pathologic version and inclination, which can be done in any commercially available software program while following these basic principles (Video 1).

Step 2 Define Premorbid Glenoid Morphology: Carefully evaluate for the presence of the native glenoid, noting its version and inclination, and be careful to distinguish the true native glenoid from osteophytes (Video 2). Read More

Giant and Very Large Intracranial Aneurysms: Surgical Strategies and Special Issues.

Acta Neurochir Suppl 2018;129:25-31

Department of Neurosurgery, San Salvatore City Hospital, L'Aquila, Italy.

Giant intracranial aneurysms (GIAs) and very large intracranial aneurysms (VLAs) have a poor natural history because of a high incidence of bleeding and strokes. These lesions always represent a great challenge for neurosurgeons and interventional neuroradiologists because of some peculiar intrinsic features such as size, angioarchitecture, wide neck, mass effect, intraluminal thrombosis, atherosclerotic changes, involvement of branches and perforators, and a frequent need to perform revascularization procedures. The results of a cumulative surgical series of 75 VLAs and GIAs are reported. Read More

Washing the Femoral Canal Results in More Predictable Seating of a Short, Tapered Femoral Stem.

J Arthroplasty 2018 Oct 19;33(10):3220-3225. Epub 2018 Jun 19.

Division of Orthopaedic Surgery, Jo Miller Orthopaedic Lab, McGill University, Montreal, Canada.

Background: It is critical that a femoral rasp be effective in preparing the proximal femur to accept the size and the geometry of the femoral implant at the time of total hip arthroplasty. Short, tapered femoral stems may be at greater risk because they require the preparation of a short femoral region without any reaming. We undertook a study to determine the effect on implant seating in femora that were prepared by rasping alone with those that were rasped and the canal was washed with saline at the time of cementless THA with a short, tapered femoral implant.

This study determined differences in spinal-pelvic kinematics sitting on (i) mat (ii) block and (iii) novel 10º forward inclined wedge (Buttafly) in a same-subject repeated measures cross-over design in 60 healthy individuals (34 females). Repeated measures ANOVA revealed statistically significant differences between sitting conditions and lumbar and pelvic sagittal angles. Both, the inclined wedge and the block seating aids reduced overall flexion, but the inclined wedge had a greater influence in the lumbar region whilst the block induced the greatest change in the pelvis.

A Randomized Controlled Trial of a Truck Seat Intervention: Part 1-Assessment of Whole Body Vibration Exposures.

Ann Work Expo Health 2018 Oct;62(8):990-999

Environmental and Occupational Health Program, School of Biological and Population Health Sciences, Oregon State University, Corvallis, OR, USA.

Full-time vehicle and heavy equipment operators often have a high prevalence of musculoskeletal disorders, especially low back pain (LBP). In occupations requiring vehicles or heavy equipment operation, exposure to whole body vibration (WBV) has been consistently associated with LBP. LBP is the most common cause of work-related disability and continues to be the leading cause of morbidity and lost productivity in the US workforce. Read More

A Randomized Controlled Trial of a Truck Seat Intervention: Part 2-Associations Between Whole-Body Vibration Exposures and Health Outcomes.

Ann Work Expo Health 2018 Oct;62(8):1000-1011

Department of Environmental and Occupational Health Sciences, University of Washington, Seattle, WA, USA.

This randomized controlled trial study was conducted to determine whether two different seating interventions would reduce exposure to whole-body vibration (WBV) and improve associated health outcomes. Forty professional truck drivers were randomly assigned to two groups: (i) a control group of 20 drivers who received a new, industry-standard air-suspension seat, and (ii) an intervention group of 20 drivers who received an active-suspension seat. This study collected regional body pain (10-point scale), low back disability [Oswestry Disability Index (ODI)], physical and mental health [the Short Form 12-item Health Survey (SF-12)], and work limitations [Work Limitation Questionnaire (WLQ)] before and 3, 6, and 12 months after the seating intervention.

Identity, Semiotics, and Use of Symbols in Adult Day Services.

Gerontologist 2018 07;58(4):730-738

Department of Sociology and Anthropology, Center for Aging Studies, University of Maryland Baltimore County (UMBC).

Purpose: This article explores experiences of older adults attending an Adult Day Service (ADS) center. We focus on semiotics, which is ADS clients' use of symbols to communicate with others and to assert their personal and social identities. We refer to the ADS as a semiosphere-a term that refers to the dense, symbolically mediated interactions among this community. Read More

Microclimate evaluation of strap-based wheelchair seating systems for persons with spinal cord injury: A pilot study.

J Tissue Viability 2018 Aug 12;27(3):181-187. Epub 2018 Jun 12.

1 Veterans Drive (151), Minneapolis VA Health Care System, Minneapolis, MN, 55417, USA; Department of Rehabilitation Medicine, University of Minnesota, Minneapolis, MN, 55455, USA.

Study Purpose: The purpose of this pilot study was to assess microclimate characteristics of two versions of a strap-based wheelchair seating system (perforated and solid straps) and to conduct preliminary microclimate comparisons of subjects' current wheelchair seating systems.

Materials And Methods: In this pilot study, the microclimate properties of two variations (solid and perforated) of a strap-based seating system were compared with two commonly used seating systems. Six subjects sat on three different seating systems each for 100-min test periods, while temperature and relative humidity were measured with a single sensor adjacent to the skin-seat interface.
