RESUMO
OBJECTIVES: Approximately 81% of traumatic brain injury cases are considered to be mild (mTBI), but few studies have reviewed mTBI caused by workplace violence (WPV). This study aimed to (1) determine the incidence of mTBI secondary to WPV in a statewide workers' compensation system using International Classification of Disease codes and (2) analyse and compare factors associated with return-to-work outcomes between WPV mTBI cases versus other mechanisms. METHODS: Using a retrospective cohort of claims data from the California Workers' Compensation Information System during 2015-2019, cases with a return-to-work date were classified as WPV if the injury description contained keywords such as assault, gunpoint, harassed, intimidated, punch, threat, robbery, violent or verbal abuse. RESULTS: Of the 14 089 mTBI claims analysed in this study, 11.2% were caused by WPV. When comparing WPV to non-WPV claims, the variables with statistically significant (p≤0.001) differences were age, income, industry and job class. There were no significant differences between groups for leave duration. In a linear mixed model, the variable of interest (WPV) was not associated with recovery duration after adjusting for other factors. CONCLUSION: To our knowledge, this is the first study to examine WPV mTBI claims in the USA. The findings suggest that the public administration, education and healthcare and social services industries are at higher risk for WPV mTBI. WPV and job class were the only modifiable factors in the model and therefore should be the focus of additional research.
RESUMO
BACKGROUND: With rising temperature extremes, older workers are becoming increasingly vulnerable to heat-related injuries because of age- and disease-associated decrements in thermoregulatory function. Endothelial monocyte-activating polypeptide-II (EMAP-II) is a proinflammatory cytokine that has not yet been well-characterized during heat stress, and which may mediate the inflammatory response to high levels of physiological strain. METHODS: We evaluated serum EMAP-II concentrations before and after 180 min of moderate-intensity work (200 W/m2 ) in temperate (wet-bulb globe temperature [WBGT] 16°C) and hot (WBGT 32°C) environments in heat-unacclimatized, healthy young (n = 13; mean [SD]; 22 [3] years) and older men (n = 12; 59 [4] years), and unacclimatized older men with hypertension (HTN) (n = 10; 60 [4] years) or type 2 diabetes (T2D) (n = 9; 60 [5] years). Core temperature and heart rate were measured continuously. RESULTS: In the hot environment, work tolerance time was lower in older men with HTN and T2D compared to healthy older men (both p < 0.049). While core temperature and heart rate reserve increased significantly (p < 0.001), they did not differ across groups. End-exercise serum EMAP-II concentrations were higher in young men relative to their older counterparts due to higher baseline levels (both p ≤ 0.02). Elevations in serum EMAP-II concentrations were similar between healthy older men and older men with HTN, while serum EMAP-II concentrations did not change in older men with T2D following prolonged work in the heat. CONCLUSION: Serum EMAP-II concentrations increased following prolonged moderate-intensity work in the heat and this response is influenced by age and the presence of HTN or T2D.

OBJECTIVE: The objective of the review is to examine the association between comorbidity and functional outcomes after hip fracture. INTRODUCTION: Patients who have suffered a hip fracture are at risk of poor functional recovery, which may be influenced by factors such as age, functional status at baseline, and comorbid conditions. Patients recovering from a hip fracture seldom present without other comorbid conditions. This proposed review will lead to a better understanding of the association between comorbidity and functional recovery after hip fracture and will assist in the medical support of patients recovering from these injuries. INCLUSION CRITERIA: Systematic reviews that include cohort studies reporting on comorbidity and functional outcomes after hip fracture in adults (≥ 18 years old) published at any time will be included. Study protocols, papers that are not systematic reviews, papers not reporting on comorbidities or functional outcomes, and papers published in languages other than English will be excluded from the review. METHODS: The JBI methodology for umbrella reviews will be followed. MEDLINE, Embase, and the Cochrane Database of Systematic Reviews will be searched. Two reviewers will screen the titles and abstracts against the eligibility criteria. Data extraction will be performed by 2 independent reviewers on the reviews selected for inclusion. Extracted study characteristics will include the author, year published, databases searched, number of studies/patients included, comorbidity measures, functional outcomes, presence of meta-analysis, and bias appraisal results. The quality of included studies will be reported using the JBI critical appraisal checklist for systematic reviews and research syntheses. A summary of the extracted data will be presented in tabular format and a narrative synthesis will be performed on the collected systematic reviews that meet the inclusion criteria. SYSTEMATIC REVIEW REGISTRATION NUMBER: PROSPERO CRD42021272502.

OBJECTIVE: To describe the sociodemographic features, impairments, and functional changes of COVID-19-positive individuals who underwent inpatient rehabilitation at three rehabilitation hospitals in Toronto, Canada. DESIGN: Retrospective chart review of patients admitted to three COVID-19 rehabilitation units between 20 April 2020 and 3 June 2020. Sociodemographic factors, impairments, length of stay, and Functional Independence Measure data were reported. RESULTS: A total of 41 patients were included in this study, including 22 males and 19 females. The median age was 75 years. Thirty-six percent of patients were admitted to the intensive care unit during their acute stay. The most commonly affected body functions were: neuromusculoskeletal (73.2%); combined cardiovascular, haematological, immunological, and respiratory (65.9%); and mental functions (29.3%). Median total Functional Independence Measure score was 85 at admission and 108.5 at discharge. CONCLUSION: This study represents some of the first data on the characteristics and outcomes of COVID-19-positive individuals admitted to inpatient rehabilitation in Toronto, Canada early in the COVID-19 pandemic.
RESUMO
BACKGROUND: Compared to other patient population groups, the field of amputation research in Canada lacks cohesion largely due to limited funding sources, lack of connection among research scientists, and loose ties among geographically dispersed healthcare centres, research institutes and advocacy groups. As a result, advances in clinical care are hampered and ultimately negatively influence outcomes of persons living with limb loss. OBJECTIVE: To stimulate a national strategy on advancing amputation research in Canada, a consensus-workshop was organized with an expert panel of stakeholders to identify key research priorities and potential strategies to build researcher and funding capacity in the field. METHODS: A modified Delphi approach was used to gain consensus on identifying and selecting an initial set of priorities for building research capacity in the field of amputation. This included an anonymous pre-meeting survey (N = 31 respondents) followed by an in-person consensus-workshop meeting that hosted 38 stakeholders (researchers, physiatrists, surgeons, prosthetists, occupational and physical therapists, community advocates, and people with limb loss). RESULTS: The top three identified research priorities were: (1) developing a national dataset; (2) obtaining health economic data to illustrate the burden of amputation to the healthcare system and to patients; and (3) improving strategies related to outcome measurement in patients with limb loss (e.g. identifying, validating, and/or developing outcome measures). Strategies for moving these priorities into action were also developed. CONCLUSIONS: The consensus-workshop provided an initial roadmap for limb loss research in Canada, and the event served as an important catalyst for stakeholders to initiate collaborations for moving identified priorities into action. Given the increasing number of people undergoing an amputation, there needs to be a stronger Canadian collaborative approach to generate the necessary research to enhance evidence-based clinical care and policy decision-making.IMPLICATIONS FOR REHABILITATIONLimb loss is a growing concern across North America, with lower-extremity amputations occurring due to complications arising from diabetes being a major cause.To advance knowledge about limb loss and to improve clinical care for this population, stronger connections are needed across the continuum of care (acute, rehabilitation, community) and across sectors (clinical, advocacy, industry and research).There are new surgical techniques, technologies, and rehabilitation approaches being explored to improve the health, mobility and community participation of people with limb loss, but further research evidence is needed to demonstrate efficacy and to better integrate them into standard clinical care.

BACKGROUND: Obesity is a known risk factor for stroke, but its impact on functional recovery is less clear. Understanding the effect of obesity on functional recovery during inpatient rehabilitation will aid clinicians in patient counselling and help administrators with program planning. OBJECTIVE: To determine if obesity affects the functional outcomes of adults undergoing inpatient stroke rehabilitation. METHODS: MEDLINE, Embase, CINAHL, and Cochrane databases were searched using the subject headings and text word terms for stroke, rehabilitation, and obesity. Two independent reviewers screened the articles against pre-defined eligibility criteria and extracted the data. Outcomes of interest included FIM, mRS, Fugl-Meyer Assessment of Sensorimotor Recovery after Stroke, and Barthel Index. RESULTS: Seven studies from five countries with a total of 3070 participants were included. There was significant heterogeneity among the studies in the BMI cut-off points and functional outcome measures used. Two studies found a positive association between obesity and functional outcome, two studies found no association, and three studies reported a negative relationship. CONCLUSIONS: No conclusions could be drawn regarding whether the functional outcome of adults undergoing inpatient stroke rehabilitation differ between individuals with and without obesity.

The risk for complications associated with joint and soft-tissue injections in patients taking direct oral anticoagulants (DOACs) is not fully understood. In this retrospective evaluation of 445 inpatients in a rehabilitation hospital who received corticosteroid injections, complications were compared in patients on DOACs with those who were not. After a review of all injections, no adverse events of significant bleeding (intra-articular or extra-articular) were observed. These findings suggest no substantial increase in adverse events associated with the use of DOACs when performing joint and soft-tissue injection procedures in inpatient rehabilitation setting.

A 26-year-old female chemist formulated polymers and coatings usually using silver ink particles. When she later began working with nickel nanoparticle powder weighed out and handled on a lab bench with no protective measures, she developed throat irritation, nasal congestion, "post nasal drip," facial flushing, and new skin reactions to her earrings and belt buckle which were temporally related to working with the nanoparticles. Subsequently she was found to have a positive reaction to nickel on the T.R.U.E. patch test, and a normal range FEV1 that increased by 16% post bronchodilator. It was difficult returning her to work even in other parts of the building due to recurrence of symptoms. This incident triggered the company to make plans for better control measures for working with nickel nanoparticles. In conclusion, a worker developed nickel sensitization when working with nanoparticle nickel powder in a setting without any special respiratory protection or control measures.

BACKGROUND: We evaluated the acute cardiovascular and thermoregulatory responses to repeated 70 degrees head-up tilts (HUT) performed following exercise-induced hyperthermia. METHODS: Eight male subjects underwent intermittent episodes of 70 degrees HUT in either a non-exercise/ non-heat stress state (NH) or an exercise-induced hyperthermic state (EIH). Subjects remained supine for 30 min in a thermoneutral environment (22 degrees C) and were subsequently exposed to three successive 6-min 70 degrees head-up tilts (HUT1, HUT2, HUT3), each separated by 10 min of supine resting. During EIH, subjects were rendered hyperthermic by exercise in the heat (core temperature of approximately 40.0 degrees C) and were then transferred to an ambient temperature of 22 degrees C. We evaluated the relative change in hemodynamic and thermal responses from the last minute in the supine position preceding the HUT to the final minute in HUT. RESULTS: While we measured a difference in the relative change in heart rate between conditions for all HUTs, no differences were observed in mean arterial pressure (MAP), total peripheral resistance, or cardiac output. A reduced change in baroreceptor sensitivity was measured in EIH for HUT1 only (-2 +/- 1 ms x mmHg(-1) following EIH compared to -13 +/- 3 ms x mmHg(-1) during NH). A significant transient reduction in cutaneous vascular conductance (CVC) occurred during HUT1 and HUT2 following EIH (-20 +/- 5% CVCmax and -9 +/- 3 %CVCmax, respectively), despite significant elevations in core temperature above resting levels (i.e., 1.4 degrees C and 0.9 degrees C for HUT1 and HUT2). CONCLUSION: We conclude that the maintenance of MAP following exercise in the heat is mitigated by reductions in skin perfusion despite significant elevations in core temperature.

We evaluated the hypothesis that with increasing levels of hyperthermia, thermal influences would predominate over nonthermal baroreceptor control of cutaneous vascular conductance (CVC) and local sweat rate (LSR). On separate days, eight male participants were positioned in either an upright seated posture (URS) or a 15 degrees head-down tilt (HDT) posture in a thermoneutral condition and during passive heating, until mean body temperature (T(body)) increased by 1.5 degrees C. Hemodynamic [heart rate (HR), cardiac output, mean arterial pressure (MAP)] and thermal responses [T(re), CVC, LSR] were measured continuously. MAP showed a gradual decrease in the early- to mid-stages of heating for both HDT and URS. At a T(body) > 0.6 degrees C, MAP achieved a stable, albeit reduced level from baseline resting for the duration of the heating, whereas MAP decreased significantly throughout the heating period in the URS position (p < 0.001). CVC increased rapidly in the early stages of heating and achieved a stable elevated level in both HDT and URS at the mid-stage of heating (T(body) increase Assuntos
