The functional impact of a traumatic hand injury: a comparison of rural/remote and metropolitan/regional populations

Background/Aims:

The aim of this research was to explore the commonalities and differences in the issues associated with the functional recovery and rehabilitation of a traumatic hand injury experienced by people in rural/remote and metropolitan/regional areas of North Queensland, Australia.

Methods:

Responses to a previously mailed survey exploring the functional impact on a rural/remote population and a metropolitan/regional population were used for analysis and comparison.

Findings:

Both populations reported a loss of movement, pain and stiffness, and a significantly greater percentage of metropolitan/regional respondents reported a loss of strength. Leisure and work tasks were affected for both groups as a result of their impairment. Rural and remote respondents would have liked more appointments but found that it was expensive to get to them. There was a significant reduction for both populations of respondents reporting their occupation as labourers after having a hand injury. There was also a significant increase in those who reported undertaking home duties, were pensioners or unemployed.

Conclusion:

A traumatic hand injury can have a moderate to extreme impact on work and leisure, regardless of residential location. Contextual factors related to living in rural and remote areas can be both a barrier and a facilitator to participation in functional activities. A review of service provision in rural/remote areas to address concerns regarding the expense of attending appointments and the minimal number of appointments required for rural and remote residents following a traumatic hand injury is recommended. Distance technology such as telehealth can increase flexibility of treatment and reduce the requirement to travel. The ongoing development and implementation of this technology is important to facilitate equitable health care between rural/remote and metropolitan/regional populations.

Physical disabilities in Asia: A meta-synthesis of qualitative literature written in English

Introduction

Research shows that occupational therapists and occupational therapy students are increasingly taking up positions in cross-cultural contexts where occupational form, social values and understanding of occupation are different to Western norms. It may be difficult for the occupational therapist to identify the implication of cultural differences.

Method

This meta-synthesis investigated lived experience of physical disability in East and Southeast Asia with the aim of identifying local understandings of disability, using the technique of meta-ethnography as described by Noblit and Hare.

Findings

Fourteen articles met the selection criteria and six overarching themes were identified concerning disability in Asia: theme (1), the influence of disability on relationships within primary groups; theme (2), journeys in resilience vary among individuals; theme (3), managing poor health makes disability difficult; theme (4), education is important and difficult for people with disabilities to achieve; theme (5), financial hardship is closely linked to disability; and theme (6), values and beliefs are enmeshed in the experiences of living with disabilities.

Conclusion

There is a wide range of experiences of disability. Occupational therapy services and research may be more effective for people with disabilities in cross-cultural settings, when these factors are investigated and incorporated into practice.

Abstract P4-04-03: Targeting of phosphatidylserine by monoclonal antibodies augments the activity of immune checkpoint inhibitor PD-1/PD-L1 therapy in murine breast tumors

Phosphatidylserine (PS) is a phospholipid that typically resides in the inner leaflet of the plasma membrane in many types of cells, including both tumor and tumor associated endothelial cells. Conditions that cause cellular stress, including those that occur from oxygen radicals, hypoxia, irradiation, and chemotherapy, cause a dramatic shift in PS localization. This change in localization results in PS shifting to the outer plasma membrane, allowing its recognition by components of the tumor microenvironment. Recognition of PS promotes an immunosuppressive environment that encourages tumor growth, in part by promoting the recruitment of myeloid derived suppressor cells, immature dendritic cells, and M2-like macrophages, in addition to inducing production of anti-inflammatory cytokines. Currently the chimeric PS-targeting antibody, bavituximab, is being used in combination with chemotherapies to treat patients with solid tumors in multiple late-stage clinical trials, where it is believe to help augment the efficacy of chemotherapeutics by blockade of PS-mediated immunosuppression and triggering an Fc-FcR mediated pro-inflammatory response in the tumor microenvironment. While the results with PS targeting therapies with chemotherapeutics are encouraging, the effectiveness of PS targeting therapies in conjunction with therapies towards immune checkpoint regulators remains largely unknown. To better understand the role of PS-targeting in breast cancers, and its effectiveness when used in combination with checkpoint inhibitors, immune competent mice harboring either EMT-6 or E0771 breast tumors were utilized. Treatments comprised PS targeting antibodies and an anti-PD1 antibody (to interrupt the PD-1/PD-L1 signaling axis) either alone or in combination with each other, and the effect on tumor growth and immune suppression determined. In both models, which showed differential sensitivity to therapy, the inclusion of PS targeting antibodies with the checkpoint blocker antibody had a significantly greater anti-tumor response than either single agent alone.

How well do physical activity questions perform? A European cognitive testing study

BACKGROUND

Only few studies have focused on the cognitive processes of the respondents that are involved when answering physical activity questionnaires (PAQs). This study aimed at examining whether two PAQs work as intended with different segments of the survey population in different cultural settings in Europe.

METHODS

The International Physical Activity Questionnaire - Short Form (IPAQ-SF) and the US National Health Interview Survey - Adult Core Physical Activity Questionnaire (NHIS-PAQ) were tested in Belgium, Estonia, Germany and the UK using a standardized cognitive interviewing procedure. IPAQ-SF measures total vigorous physical activity (PA), moderate PA, walking and sitting. NHIS-PAQ measures leisure-time vigorous PA, light and moderate PA and muscle-strengthening PA. In total 62 persons completed cognitive interviews, at least 15 interviews were conducted in each country.

RESULTS

Both PAQs performed as intended with young and high-skilled persons and those having a regular exercise schedule. For the others, however, the testing revealed that problems occurred with both PAQs relating to understanding the concepts of '(light and) moderate' and 'vigorous' PA, classifying activities into the provided answer options of different PA intensities, recalling instances of 'normal' activities such as walking and sitting, and calculating the total duration of more than one activity or instance of an activity. The revealed problems with the questionnaires were quite similar in different countries; profound cultural differences were not observed.

CONCLUSIONS

Both questionnaires were difficult to answer for many respondents and rather user-unfriendly. They are designed to measure an exactness of PA quantity (frequency and duration) and intensity which would be desirable to obtain from a scientific point of view; however, respondents can hardly provide this information for cognitive reasons. Studies investigating the respondents' perspective are useful for improving physical activity information based on self-reports.

Intrarenal B Cell Cytokines Promote Transplant Fibrosis and Tubular Atrophy

Renal transplantation is the optimum treatment for end-stage renal failure. B cells have been identified in chronic allograft damage (CAD) and associated with the development of tertiary lymphoid tissue within the human renal allograft. We performed renal transplantation in mice to model CAD and identified B cells forming tertiary lymphoid tissue with germinal centers. Intra-allograft B220(+) B cells comprised of IgM(high) CD23(-) B cells, IgM(lo) CD23(+) B cells, and IgM(lo) CD23(-) B cells with elevated expression of CD86. Depletion of B cells with anti-CD20 was associated with an improvement in CAD but only when administered after transplantation and not before. Isolated intra-allograft B cells were cultured and shown to synthesize multiple cytokines, the most abundant of these were GRO-α (CXCL1), RANTES (CCL5), IL-6 and MCP-1 (CCL2). Tubular loss was observed with T cell accumulation within the allograft and development of interstitial fibrosis, whilst type III collagen deposition was observed in areas of F4/80(+) macrophages and PDGFR-β(+) and transgelin(+) fibroblasts, all of which were reduced by B cell depletion. We have shown that intra-allograft B cells are key mediators of CAD. B cells possibly contribute to CAD by intra-allograft secretion of cytokines and chemokines.

Differences in regional adiposity, bone mineral density, and physical exercise participation based on exercise self-efficacy among senior adults

AIM

The impact of exercise self-efficacy levels (ESE) on exercise participation, levels of body fat (BF), and bone mineral density (BMD) are unclear in senior-aged adults. The purpose of this study was to investigate effects of ESE on exercise participation, regional distribution of BF, and BMD among seniors.

METHODS

Senior adults (N.=76; 36 males, 40 females) were separated into tertiles (T1, age=60.4±1.4; T2, age=61.3±1.4; T3, age=60.4±1.5) based on self-reported levels of ESE. BMD and regional BF were measured using dual-energy x-ray absorptiometry and exercise participation levels were measured using the Rapid Physical-Activity Questionnaire.

RESULTS

MANOVA revealed a significant Wilks Lambda (p < 0.001) and univariate analysis was completed for exercise participation levels, android BF, gynoid BF, and spinal BMD. ANOVA revealed T3 was significantly lower for android BF (p=0.002) than T1 and T2 (30% and 26%, respectively) while gynoid BF was significantly lower (p=0.012) for T3 (24%) compared to T1. When evaluating exercise participation levels, T3 was significantly higher (p < 0.001) than T1 or T2. Spinal BMD was significantly higher (p=0.030) between T2 (10%) and T1.

CONCLUSION

ESE is an important factor in senior adults ability to maintain longitudinal health.

Incremental effects of 28 days of beta-alanine supplementation on high-intensity cycling performance and blood lactate in masters female cyclists

Within the aging population, there exists a subset of individuals termed masters athletes (MA). As masters-level competition increases in popularity, MA must find methods to enhance individual athletic performance. Longitudinal beta-alanine (BA) supplementation is suggested to enhance physical capability during exercise; however, these effects have not been evaluated in MA. To examine the longitudinal effects of BA on time to exhaustion (TTE), total work completed (TWC), and lactate clearance in female MA cyclists. Twenty-two female MA (age = 53.3 ± 1.0) participated in this double-blind design. Subjects were randomly assigned to BA (n = 11; 800 mg BA + 8 g dextrose) or placebo (PLA; n = 11; 8 g dextrose) groups and supplemented 4 doses/day over 28 days. Every 7 days, subjects completed a cycling TTE at 120% VO2max, and TWC was calculated. Blood lactate was measured at baseline, immediate post, and 20-min post each TTE. No significant differences existed between groups for any variable at baseline (p > 0.05). After 28 days supplementation, BA had greater TTE (23 vs 1% change) and TWC (21 vs 2% change) than PLA (p < 0.05). Following the 20-min TTE recovery, lactate was 24% lower in BA compared to PLA (4.35 vs. 5.76 mmol/L, respectively). No differences existed for variables during intermittent weeks. 28 days of BA supplementation increased cycling performance via an enhanced time to exhaustion and total work completed with associated lactate clearance during passive rest in female MA.

Early Intervention in Children (0–6 Years) with a Rare Developmental Disability: The Occupational Therapy Role

Objective/Background

This study aims to explore the occupational therapists’ role in early intervention for children diagnosed with a rare developmental disability.

Methods

A survey was distributed by mail or online, to eligible occupational therapists currently used by the Disability and Community Care Services throughout Queensland, Australia. Eligible occupational therapists were those working with children aged 0–6 years. Two in-depth phone interviews were also undertaken.

Results

Eleven participants who had previously worked with at least one child with a rare developmental disability returned the survey. One participant nominated for a follow-up interview and a second interview with a speech and language pathologist was conducted to gain a multidisciplinary perspective. The most common areas requiring intervention were play support (85.3%), activities of daily living, communication, gross motor, and fine motor skills (79.4%).

Conclusion

Family-centred practice, play therapy, and individually tailored programmes are identified as key practice areas for this population. The important role occupational therapists play in early intervention teams is highlighted; however, further research is needed to develop the evidence base for best practice with particular rare developmental conditions.

Treatment of congenital pulmonary lymphangiectasia using ethiodized oil lymphangiography

Historically, congenital pulmonary lymphangiectasia (CPL) has had poor treatment outcomes despite aggressive therapy. There are recent reports of ethiodized oil (Lipiodol) lymphangiography successfully treating lymphatic leakage in adults. In this report, we describe two infants with CPL complicated by chylothoraces successfully treated by instillation of ethiodized oil into the lymphatic system. Congenital atresia of the thoracic duct was demonstrated on the lymphangiogram in both patients before treatment. Both patients have shown good short-term outcomes without supplemental oxygen or fat restricted diets at 9 months of age. Ethiodized oil lymphangiography represents a new treatment modality for some patients with CPL.

Integrating molecular diagnostics into histopathology training: the Belfast model

Molecular medicine is transforming modern clinical practice, from diagnostics to therapeutics. Discoveries in research are being incorporated into the clinical setting with increasing rapidity. This transformation is also deeply changing the way we practise pathology. The great advances in cell and molecular biology which have accelerated our understanding of the pathogenesis of solid tumours have been embraced with variable degrees of enthusiasm by diverse medical professional specialties. While histopathologists have not been prompt to adopt molecular diagnostics to date, the need to incorporate molecular pathology into the training of future histopathologists is imperative. Our goal is to create, within an existing 5-year histopathology training curriculum, the structure for formal substantial teaching of molecular diagnostics. This specialist training has two main goals: (1) to equip future practising histopathologists with basic knowledge of molecular diagnostics and (2) to create the option for those interested in a subspecialty experience in tissue molecular diagnostics to pursue this training. It is our belief that this training will help to maintain in future the role of the pathologist at the centre of patient care as the integrator of clinical, morphological and molecular information.

New graduate occupational therapists' perceptions of near-misses and mistakes in the workplace

PURPOSE

The purpose of this paper is to explore the perceptions of near-misses and mistakes among new graduate occupational therapists from Australia and Aotearoa/New Zealand (NZ), and their knowledge of current incident reporting systems.

DESIGN/METHODOLOGY/APPROACH

New graduate occupational therapists in Australia and Aotearoa/NZ in their first year of practice (n = 228) participated in an online electronic survey that examined five areas of work preparedness. Near-misses and mistakes was one focus area.

FINDINGS

The occurrence and disclosure of practice errors among new graduate occupational therapists are similar between Australian and Aotearoa/NZ participants. Rural location, structured supervision and registration status significantly influenced the perceptions and reporting of practice errors. Structured supervision significantly impacted on reporting procedure knowledge. Current registration status was strongly correlated with perceptions that the workplace encouraged event reporting.

RESEARCH LIMITATIONS/IMPLICATIONS

Areas for further investigation include investigating the perceptions and knowledge of practice errors within a broader profession and the need to explore definitional aspects and contextual factors of adverse events that occur in allied health settings. Selection bias may be a factor in this study.

PRACTICAL IMPLICATIONS

Findings have implications for university and workplace structures, such as clinical management, supervision, training about practice errors and reporting mechanisms in allied health.

ORIGINALITY/VALUE

Findings may enable the development of better strategies for detecting, managing and preventing practice errors in the allied health professions.

Community integration after traumatic brain injury: a systematic review of the clinical implications of measurement and service provision for older adults

OBJECTIVE

To explore the scope, reliability, and validity of community integration measures for older adults after traumatic brain injury (TBI).

DATA SOURCES

A search of peer-reviewed articles in English from 1990 to April 2011 was conducted using the EBSCO Health and Scopus databases. Search terms included were community integration, traumatic brain injury or TBI, 65 plus or older adults, and assessment.

STUDY SELECTION

Forty-three eligible articles were identified, with 11 selected for full review using a standardized critical review method.

DATA EXTRACTION

Common community integration measures were identified and ranked for relevance and psychometric properties. Of the 43 eligible articles, studies reporting community integration outcomes post-TBI were identified and critically reviewed. Older adults' community integration needs post-TBI from high quality studies were summarized.

DATA SYNTHESIS

There is a relative lack of evidence pertaining to older adults post-TBI, but indicators are that older adults have poorer outcomes than their younger counterparts. The Community Integration Questionnaire (CIQ) is the most widely used community integration measurement tool used in research for people with TBI. Because of some limitations, many studies have used the CIQ in conjunction with other measures to better quantify and/or monitor changes in community integration.

CONCLUSIONS

Enhancing integration of older adults after TBI into their community of choice, with particular emphasis on social integration and quality of life, should be a primary rehabilitation goal. However, more research is needed to inform best practice guidelines to meet the needs of this growing TBI population. It is recommended that subjective tools, such as quality of life measures, are used in conjunction with well-established community integration measures, such as the CIQ, during the assessment process.

The effects of power and strength training on bone mineral density in premenopausal women

AIM

The purpose of this 48-week exercise intervention was designed to examine the effects of power and resistance training on bone mineral density (BMD).

METHODS

Premenopausal women were recruited and randomly assigned to either a power (N.=8) or resistance (N.=11) training group. The power exercises included jumping rope, skipping, hopping, and other power-type exercises. The resistance training group performed 8-10 whole-body strengthening exercises at 70% one-repetition maximum (1RM). Before and after the exercise intervention, BMD was measured via dual energy x-ray absorptiometry (DXA) for the total-body, lumbar spine, left femoral neck, and left greater trochanter. Muscular strength was measured by hand grip dynamometer and 1RM of chest press and leg press. Muscular power was assessed by the Margaria-Kalamen stair climb test. Data were analyzed using repeated measures ANOVA.

RESULTS

There were no statistical differences between the two training groups for any of the BMD measurements. Chest press strength was different between the two groups, increasing 6.41 and 1.1kg for the resistance and power groups, respectively over the course of the training period (F[1.15]=9.44, P<0.01). There was a significant time effect for leg press 1RM (F[1.15]=6.04, P=0.03). The participants increased by 12.37kg after the 48-week intervention. Hand grip strength also increased after the study intervention (F[1.16]=46.32, P<0.01).

CONCLUSION

The results of this study suggest that power and resistance training are comparable techniques for maintaining bone density.

The use of focus groups to develop a culturally relevant quality of life tool for lymphatic filariasis in Bangladesh

PURPOSE

The purpose of this study was to conduct focus groups to operationalise the construct of quality of life (QOL) for people living with lymphatic filariasis (LF) in Bangladesh to develop culturally valid items for a Bangladeshi LF QOL tool.

METHODS

Ten focus groups were conducted with a stratified purposeful sample (n = 60) of LF patients (3 focus groups, n = 17), doctors (1 focus group, n = 5), nurses (1 focus group, n = 6) and other hospital staff (1 focus group, n = 5), community leaders (2 focus groups, n = 14), community volunteer health workers (1 focus group, n = 5) and Bangladeshi LF researchers and planners (1 focus group, n = 8). Focus group methodology was informed by local culture in consultation with cultural mentors and local advisors, often going against standard focus group procedures. Data were collected through note taking, audio taping, transcripts, observational notes and a reflection diary. Open coding of transcript data was completed until data saturation was achieved.

RESULTS

Forty-three constructs were identified through the focus groups that had not previously been identified in the literature, including constructs relating to environmental supports and barriers, activities, participation and psychological impacts. There were marked differences between the impacts reported by different groups, highlighting the need for a comprehensive purposive sample. In particular, contributions from participants who would not traditionally be viewed as "experts" were vital.

CONCLUSIONS

The use of focus groups strongly contributed to the operationalisation of the concept of QOL in Bangladesh for people living with LF. Use of literature review or expert opinion alone would have missed vital constructs.
