A conceptual model and detailed framework for stress-related,strain-related,and overuse athletic injury

A multitude of athletic injuries occur when the various tissues that make up the human body experience stresses and strains that exceed their material strength. The precise amount of stress and strain that any given tissue can withstand is determined by the mechanical properties and resultant strength of that particular tissue. These mechanical properties are directly determined by an individual’s physiology and acute regulation of these properties. A number of theoretical frameworks for athletic injury occurrence have been proposed, however, a detailed conceptual framework for injury aetiology that considers the interplay between the physiological and mechanical factors and outlines the causal pathways to tissue damage and injury is needed. This will guide injury research towards a more thorough investigation of causal mechanisms and understanding of risk factors. Further, it is important to take into account the considerable differences in loading patterns which can result in varying injury outcomes such as acute stress-related, strain-related, or overuse injury. Within this article a simplified conceptual model of athletic injury is proposed along with a detailed, evidence-informed, conceptual framework for athletic injury aetiology that focuses on stress-related, strain-related, and overuse injury.     

Outcomes after occupational therapy intervention for traumatic brachial plexus injury: A prospective longitudinal cohort study

Study DesignProspective longitudinal cohort study.IntroductionTraumatic brachial plexus injuries (BPIs) can be devastating and negatively impact daily function and quality of life. Occupational therapists play an important role in rehabilitation; however, studies identifying outcomes are lacking.PurposeThis study aims to describe outcomes including motor recovery, upper limb function, participation, pain, and quality of life for people receiving occupational therapy intervention.MethodsA convenience sample of English-speaking adults (n = 30) with a traumatic BPI, attending the clinic between December 1, 2014, to November 30, 2016, participated. Participants received occupational therapy focusing on sensorimotor retraining and activity-based rehabilitation. Data on active range of motion (goniometry), strength (Medical Research Council (MRC)), upper-limb function (UEFI15, QuickDASH), participation (PSFS), pain (Brief Pain Inventory), and quality of life (EQ-5D-3L) were collected at baseline, 3, 6, 9, and 12 months.ResultsElbow flexion strength showed significant improvement at all time-points, average increase 2.17 (MRC) (95% confidence interval: 1.29-3.04; P < .001) and mean final MRC grading 3.86 (standard error: 0.44). Significant improvements at 12 months were seen in: shoulder abduction strength and range, flexion strength and range, external rotation range; elbow extension strength and flexion range; thumb flexion and extension strength. Upper limb function (QuickDASH) showed significant improvement (mean change = 18.85; 95% confidence interval: 4.12-33.59; P = .02). Forearm protonation range and finger flexion strength were significantly worse. Remaining outcomes did not show significant improvement.ConclusionsOccupational therapy with surgical intervention can improve strength, range, and upper limb function with people following traumatic BPI. Further investigations into impact on participation, pain, and quality of life are required.     

Curcumin attenuates spatial memory impairment by anti-oxidative,anti-apoptosis,and anti-inflammatory mechanism against methamphetamine neurotoxicity in male Wistar rats: Histological and biochemical changes

ObjectiveMethamphetamine is used extensively around the world as a psychostimulant. The complications related to methamphetamine include methamphetamine-induced neurotoxicity, mainly involving intraneuronal processes, such as oxidative stress and excitotoxicity. Curcumin is effective against neuronal injury due to its antioxidant, anti-inflammatory effects. In this study, we examined the protective effects of curcumin against methamphetamine neurotoxicity.MethodsSixty male Wistar rats were divided into the following groups: control (n = 12), DMSO (n = 12), methamphetamine (n = 12), and methamphetamine + curcumin (100 and 200 mg/kg, respectively, intraperitoneal [IP]; n = 12). Neurotoxicity was induced by 40 mg/kg of methamphetamine administrated through 4 injections (4 × 10 mg/kg, q2h, IP). Curcumin (100 and 200 mg/kg) was administered at 7 days after the last methamphetamine injection. By using a Morris water maze task, the hippocampus-dependent memory and spatial learning were evaluated 1 day after the last curcumin injection. Then, the animal brains were isolated for biochemical measurements, as well as glial fibrillary acidic protein (GFAP), ionized calcium-binding adaptor protein-1(Iba-1) and caspase-3 immunohistochemical staining.ResultsThe current study demonstrated that administration of curcumin significantly attenuates spatial memory impairment (P < 0.01) following methamphetamine neurotoxicity. Curcumin caused a significant increase in the levels of superoxide dismutase and glutathione peroxidase (P < 0.05). However, it decreased tumor necrosis factor (TNF-α) (P < 0.05) and malondialdehyde (P < 0.01) levels as compared to the methamphetamine group. Also, curcumin significantly reduced Iba-1 (P < 0. 01), GFAP and caspase-3 positive cells in the hippocampus (P < 0.001).ConclusionCurcumin exerted neuroprotective effects on methamphetamine neurotoxicity because of its antioxidant and anti-inflammatory effect.     

A Profile of Black and Latino Older Adults Receiving Care in Nursing Homes: 2011–2017

ObjectiveTo identify if disparate trends in the access and use of nursing home (NH) services among Black and Latino older adults compared with White older adults persist. Access was operationalized as the NHs that served Black, Latino, and White residents. Use was operationalized as the utilization of NH services by Black, Latino, and White residents.DesignThis was an observational study analyzing facility-level data from LTCfocus for 2011 to 2017.Setting and ParticipantsAll NH residents present in US NHs participating in the Centers for Medicare and Medicaid Services program on the first Thursday in April in the years 2011 to 2017. NHs with fewer than 4500 bed-days per year are excluded in the LCTfocus dataset. Black, Latino, and White were the racial/ethnic groups of interest.MethodsWe calculated the mean percentage of each racial/ethnic group in NHs (Black, Latino, White) annually along with the number of NHs that provided care for these groups. We conducted a simple trend analysis using ordinary least squares to estimate the change in NH access and use by racial/ethnic group over time.ResultsOur NH sample ranged from 15,564 in 2011 to 14,956 in 2017. Latino residents' use of NHs increased by 20.47% and Black residents increased by 11.42%, whereas there was a 1.36% decrease in White residents’ use of NHs. In this 7-year span, there was a 4.44% and 6.41% decline in the number of NHs that serve any Black and Latino older adults, respectively, compared with a 2.26% decline in NHs that serve only White older adults (access).Conclusions and ImplicationsOur findings reveal a continued disproportionate rise in Black and Latino older adults’ use of NHs while the number of NHs that serve this population have declined. This work can inform federal and state policies to ensure access to long-term care services and supports in the community for all older adults and prevent inappropriate NH closures.     

A Cross-Sectional,Correlational Study Comparing Individual Characteristics of Younger and Older Nursing Home Residents using Western Canadian Resident Assessment Instrument–Minimum Data Set (RAI-MDS) 2.0

ObjectiveTo compare characteristics of nursing home (NH) residents by age categories in Western Canada.DesignA cross-sectional, correlational analysis of secondary data.Setting and Participants89,231 residents living in Western Canada NHs in the provinces of Alberta, Manitoba, and British Columbia in 2016 and 2017.MethodsResident characteristics (age, sex, marital status, body mass index, medical diagnoses, cognitive function, physical function, depressive symptoms) came from the Resident Assessment Instrument–Minimum Data Set 2.0 and were analyzed using chi-square, analysis of variance, and post hoc pairwise tests. Human developmental stage age categories were used to create 5 age groups: 18-34, 35-50, 51-64, 65-80, and 81 years and older.ResultsThe demographics, medical diagnoses, cognitive function, and physical function characteristics of NH residents among 5 age groups differed considerably (all P < .001). Residents aged 18-34 years were predominately male, never married, with a higher incidence of paralysis and traumatic brain injury. Residents aged 35-50 years had a higher incidence of stroke and multiple sclerosis, and residents aged 51-64 years mainly were morbidly obese and more prone to depression. Residents aged 65-80 years were predominately married and more prone to diabetes, and residents aged 81 years and older were predominately widowed, with a higher incidence of dementia compared with others.Conclusions and ImplicationsFindings describe the uniqueness of younger NH age groups and indicate that the youngest NH residents often have the severe disability and a modest support system (as defined by partnered status) compared to older residents in NHs. Future studies must analyze longitudinal data that track the growth of, and changes in, residents’ health and functional status.
