Return to valued activities: Survivors' experiences of adaptation and growth after treatment for head and neck cancer.

OBJECTIVE: The objective of this study was to explore the experiences of head and neck cancer (HNC) survivors who returned to valued activities to understand how they reconstruct their lives following HNC diagnosis and treatment. METHODS: A qualitative research approach based on social constructionist theory was used. A total of 21 in-depth semi-structured interviews were conducted with adults diagnosed with any type of HNC in the previous 6 years. Reflexive thematic analysis was used to identify themes. RESULTS: HNC presents a unique trauma following which some survivors navigate paths back to meaningful activities. The experiences of HNC survivors who adapted to life after treatment described internal and external change and development, identified by three themes; Mindfulness; Gratitude; and Adaptation. CONCLUSION: People diagnosed with HNC frequently experience lasting effects and other survivorship issues, however some survivors were able to return to valued activities and recreate a meaningful lifestyle reflecting the possibility of post traumatic growth. This study provides insight into the experiences of head and neck cancer survivors who were able to make meaning and find internal and external growth following treatment. These findings can be used to inform advanced communication skills training for oncology health professionals and psychoeducational courses for people diagnosed with head and neck cancer in the future.

Anomalies in global network connectivity associated with early recovery from alcohol dependence: A network transcranial magnetic stimulation and electroencephalography study.

Although previous research in alcohol dependent populations identified alterations within local structures of the addiction 'reward' circuitry, there is limited research into global features of this network, especially in early recovery. Transcranial magnetic stimulation (TMS) is capable of non-invasively perturbing the brain network while electroencephalography (EEG) measures the network response. The current study is the first to apply a TMS inhibitory paradigm while utilising network science (graph theory) to quantify network anomalies associated with alcohol dependence. Eleven individuals with alcohol-dependence (ALD) in early recovery and 16 healthy controls (HC) were administered 75 single pulses and 75 paired-pulses (inhibitory paradigm) to both the left and right prefrontal cortex (PFC). For each participant, Pearson cross-correlation was applied to the EEG data and correlation matrices constructed. Global network measures (mean degree, clustering coefficient, local efficiency and global efficiency) were extracted for comparison between groups. Following administration of the inhibitory paired-pulse TMS to the left PFC, the ALD group exhibited altered mean degree, clustering coefficient, local efficiency and global efficiency compared to HC. Decreases in local efficiency increased the prediction of being in the ALD group, while all network metrics (following paired-pulse left TMS) were able to adequately discriminate between the groups. In the ALD group, reduced mean degree and global clustering was associated with increased severity of past alcohol use. Our study provides preliminary evidence of altered network topology in patients with alcohol dependence in early recovery. Network anomalies were predictive of high alcohol use and correlated with clinical features of alcohol dependence. Further research using this novel brain mapping technique may identify useful network biomarkers of alcohol dependence and recovery.

Neuromodulation of Attentional Control in Major Depression: A Pilot DeepTMS Study.

While Major Depressive Disorder (MDD) is primarily characterized by mood disturbances, impaired attentional control is increasingly identified as a critical feature of depression. Deep transcranial magnetic stimulation (deepTMS), a noninvasive neuromodulatory technique, can modulate neural activity and induce neuroplasticity changes in brain regions recruited by attentional processes. This study examined whether acute and long-term high-frequency repetitive deepTMS to the dorsolateral prefrontal cortex (DLPFC) can attenuate attentional deficits associated with MDD. Twenty-one MDD patients and 26 matched control subjects (CS) were administered the Beck Depression Inventory and the Sustained Attention to Response Task (SART) at baseline. MDD patients were readministered the SART and depressive assessments following a single session (n = 21) and after 4 weeks (n = 13) of high-frequency (20 Hz) repetitive deepTMS applied to the DLPFC. To control for the practice effect, CS (n = 26) were readministered the SART a further two times. The MDD group exhibited deficits in sustained attention and cognitive inhibition. Both acute and long-term high-frequency repetitive frontal deepTMS ameliorated sustained attention deficits in the MDD group. Improvement after acute deepTMS was related to attentional recovery after long-term deepTMS. Longer-term improvement in sustained attention was not related to antidepressant effects of deepTMS treatment.

Implementing a self-management intervention for people with a chronic compensable musculoskeletal injury in a workers compensation context: a process evaluation.

PURPOSE: Determining factors critical for an intervention's success, specifically for whom and under what circumstances, is necessary if interventions are to be effectively targeted and efficiently implemented. This paper describes a process evaluation undertaken to assess the implementation of a novel self-management (SM) intervention developed for those with a chronic compensable work-related musculoskeletal disorder seeking to return to work. METHODS: The process evaluation, assessing the 'Self-Management for Return to Work' intervention, examined data from program leader evaluations, telephone interviews with stakeholders (injured worker participants, vocational rehabilitation consultant program leaders and compensation insurance regulators), post-intervention focus group session feedback, attendance lists and researcher notes. RESULTS: The evaluation identified several challenges and barriers associated with conducting research within the VR environment and with the characteristics of those targeted i.e., injured workers with a chronic compensable condition. These issues were primary contributing factors to the modifications to the randomised controlled trial methodology and the trial's premature cessation. CONCLUSIONS: Despite the difficulties encountered, high stakeholder acceptability suggests that the concept and theory underlying the targeted SM intervention were not flawed, though there is room for further tailoring to both the program method and its timing. The results of this process evaluation provide a useful platform for others considering the implementation of interventions within the vocational rehabilitation context or with individuals with chronic, compensated injuries.

Work-related road traffic injury: a multilevel systems protocol.

BACKGROUND: Although road traffic injury is reported as the leading cause of work-related death in Australia, it is not clear, due to limitations in previous methods used, just how large a burden it is. Many organisations are unaware of the extent of work-related road traffic injury and, importantly, what can be done to reduce the burden. The proposed research will (i) estimate the prevalence of work-related road traffic injury and (ii) identify the organisational determinants associated with work-related road traffic injury. METHODS AND DESIGN: The current study is designed to enumerate the problem and identify the individual driver-level, the supervisor-level and organisational-level factors associated with work-related road traffic injury. The multilevel systems protocol will involve a series of cross-sectional surveys administered to drivers of fleet vehicles (n=1200), supervisors of the drivers (n=1200) and senior managers (n=300) within the same organisation. DISCUSSION: The novel use of the multilevel systems protocol is critical to be able to accurately assess the specific determinants of driving safety within each context of an organisation. RESULTS: The results are expected to highlight that reducing injury in the workplace requires more than just individual compliance with safety procedures. It will also establish, for the first time, an occupational translation taskforce to ensure that the research findings are adopted into work-place practice and thereby directly contribute to reductions in work-related road traffic injury.

'Beyond Cancer' Rehabilitation Program to Support Breast Cancer Survivors to Return to Health, Wellness and Work: Feasibility Study Outcomes.

More women are returning to work following breast cancer treatment. Our team designed 'Beyond Cancer', a multimodal rehabilitation program to support breast cancer survivors to return to work. This study aimed to determine the feasibility of the intervention from the breast cancer survivor, employer and occupational rehabilitation provider perspectives. The feasibility design focused on implementation, acceptability and preliminary indications of efficacy. Primary outcome measures included work status, work capacity and perceived support at work. Responses were compared with an historical usual care group of mixed cancer survivors. The tailored intervention was delivered over 33 weeks (on average) by trained occupational rehabilitation consultants. Eighty-four women with breast cancer (mean age = 50.8 years, SD = 8.24) who were unable to work in their pre-diagnosis capacity for >3 months participated. Results provided preliminary indications of efficacy for primary work outcomes, including work capacity relative to the historical usual care group, and some secondary biopsychosocial variables (physical fatigue, return to work expectations). The intervention was acceptable, demonstrated strong participant engagement and high satisfaction. Feasibility has been demonstrated for this multimodal intervention focused on returning to sustainable work for women with breast cancer. Future research is required with people diagnosed with other cancer types to demonstrate broader implementation.

Deficits in selective attention in symptomatic Huntington disease: assessment using an attentional blink paradigm.

BACKGROUND: Impaired selective attention in Huntington disease (HD) may manifest as difficulty in identifying a single target embedded among a series of distractors in rapid serial visual presentation tasks. METHOD: We used an attentional blink (AB) paradigm to examine whether attentional control is impaired in symptomatic HD. Fourteen HD patients and 13 age-matched healthy controls performed a rapid serial visual presentation task in which 2 targets (T1 and T2) and numerous distractors were presented in rapid succession. We assessed the accuracy of T1 identification and the AB (impaired T2 detection after the correct identification of T1). RESULTS: Among the HD patients, identification of T1 was significantly impaired and AB was significantly larger but not longer. The HD patients also made significantly more random errors. CONCLUSIONS: Frontostriatal or frontoparietal dysfunction is likely to compromise attentional control in HD, such that well-masked and rapidly presented target stimuli are difficult to detect and identify, especially as the difficulty level increases. Although we previously reported no AB deficits in presymptomatic HD, with manifest disease we found that the progressive frontoparietal cortical changes compromise attentional control mechanisms.

Applying systems thinking to improve the safety of work-related drivers: A systematic review of the literature.

INTRODUCTION: Light vehicles (<4.5 tons) driven for work purposes represent a significant proportion of the registered motor vehicles on our roads. Drivers of these vehicles have significant exposure to the dangers of the road transport environment. To optimize safety for these workers, it is critical to understand the factors contributing to risk of being involved in an incident. This information can then be used to inform the review and revision of existing risk controls and the development of targeted prevention activities. METHOD: The aim of the study was to undertake a systematic review of the literature to identify the factors associated with work-related driving incidents. The factors identified in the review were represented within an adapted version of Rasmussen's risk management framework (Rasmussen, 1997). Fifty studies were analyzed following data screening and review of full text. The highest proportion of risk factors were categorized at the lower levels of the system, including the 'Drivers and Other Road Users' level (n = 20, 44.4%) and the 'Equipment, Environment, and Meteorological Surroundings' level (n = 19, 42.2%). There were no risk factors identified at the 'Regulatory and Government Bodies' levels of the framework, confirming the narrow investigative scope of past research and the need to acknowledge a broader range of factors within and across higher levels of the system. CONCLUSIONS: The findings of this study inform the direction of future research and design of targeted prevention activities capable of creating system change for the safety of work-related drivers.

Considerations surrounding remote medicolegal assessments: a systematic search and narrative synthesis of the range of motion literature.

Remote telehealth practices were forced to advance 10 years in a few short weeks in March 2020 due to the onset of a global pandemic. In the sphere of non-clinical medicine, a dramatic element of uncertainty entered the psyche of doctors and lawyers in relation to the validity of remote or virtual independent medical examination (vIME). This paper considers the key issues surrounding the virtual assessment of clients for medicolegal purposes. Our main hypothesis was that, within certain defined parameters, the vIME technique can deliver reliable and accurate assessments. To explore this, a systematic literature search focusing on advanced device-based range of motion measurement was conducted, along with an historical snapshot of observation-based range of motion measurement considering application to remotely performed IME. While some specialists are of the view that observational measurement may be applied reliably to some joints when conducted by experienced orthopaedic surgeons, evidence for this is scant. The results, instead, support the notion of using task substitution, that is specialists appropriately assisted in conducting vIMEs by musculoskeletal trained allied health practitioners, regardless of the measurement tool, for permanent impairment assessments. Moreover, self-performed examinations by injured individuals using advanced technology are not reliable in this setting. Our final contention is that remote examinations with limited clinical assessment have utility for legal matters, such as the assessment of causation of injury, treatment advice or approvals and fitness for pre-employment tasks or safe variations, with objective clinical adjunct support such as Picture Archiving and Communication System-based modern radiology systems.

Improving injury surveillance data quality: a study based on hospitals contributing to the Victorian Emergency Minimum Dataset.

OBJECTIVE: In this paper, we describe the design and baseline data of a study aimed at improving injury surveillance data quality of hospitals contributing to the Victorian Emergency Minimum Dataset (VEMD). METHODS: The sequential study phases include a baseline analysis of data quality, direct engagement and communication with each of the emergency department (ED) hospital sites, collection of survey and interview data and ongoing monitoring. RESULTS: In 2019/20, there were 371,683 injury-related ED presentations recorded in the VEMD. Percentage unspecified, the indicator of (poor) data quality, was lowest for 'body region' (2.7%) and 'injury type' (7.4%), and highest for 'activity when injured' (29.4%). In the latter, contributing hospitals ranged from 3.0-99.9% unspecified. The 'description of event' variable had a mean word count of 10; 16/38 hospitals had a narrative word count of <5. CONCLUSIONS: Baseline hospital injury surveillance data vary vastly in data quality, leaving much room for improvement and justifying intervention as described. IMPLICATIONS FOR PUBLIC HEALTH: Hospital engagement and feedback described in this study is expected to have a marked effect on data quality from 2021 onwards. This will ensure that Victorian injury surveillance data can fulfil their purpose to accurately inform injury prevention policy and practice.

"We're on a Merry-Go-Round": Reflections of Patients and Carers after Completing Treatment for Sarcoma.

Sarcoma is a rare cancer that has a significant impact on patients' and carers' quality of life. Despite this, there has been a paucity of research exploring the diverse experiences of patients and carers following sarcoma treatment. The aim of this study was to explore patients' and carers' reflections on life after treatment for sarcoma. A qualitative research design with a social constructionist epistemology was used. Participants included patients previously treated for sarcoma (n = 21) and family carers of patients treated for sarcoma (n = 16). Participants completed semi-structured interviews which were analysed using thematic analysis. Three primary themes were identified: "This journey is never going to be over", "But what happens when I am better?", and finding a silver lining. Participants represented sarcoma as having a long-term, and sometimes indefinite, threat on their life that they had limited control over. Conclusions: This study highlight the heterogeneous and ongoing needs of sarcoma survivors and their families. Patients and carers strove to translate their experiences in a meaningful way, such as by improving outcomes for other people affected by sarcoma. Parental carers in particular attempted to protect the patient from the ongoing stress of managing the disease.

'Beyond Cancer': a study protocol of a multimodal occupational rehabilitation programme to support breast cancer survivors to return work.

INTRODUCTION: With more women working and surviving breast cancer, issues concerning sustainable employment must be addressed. Support to transition back to work is a gap in survivorship care. This paper describes the feasibility trial protocol for 'Beyond Cancer', a multimodal occupational rehabilitation programme to support breast cancer survivors' return to work. Breast cancer survivors are hypothesised to show improved work status, work capacity and perceived support at work at 6 months postintervention relative to baseline and a historical usual care group. METHODS AND ANALYSIS: The prospective feasibility design allows determination of change in primary (work status) as well as secondary outcome measures work capacity and perceived support at work. PARTICIPANTS: breast cancer survivors of working age, unable to work in their prediagnosis capacity for >3 months, their employers and a historical usual care group. Key intervention elements: an evidence-based biopsychosocial assessment and health coaching programme, employer education and support, and return to work (RTW) planning and monitoring. Health coaching empowers survivors to return to social function, including work. Employer education and support facilitates communication and improves workplace support. For employers, we predict change in confidence in effectively supporting employees' RTW. Multilevel regression modelling will provide indications of efficacy for primary and secondary outcomes, and thematic analysis will examine perceived efficacy and acceptability. ETHICS AND DISSEMINATION: Ethics approval has been granted by Monash and Curtin University Human Research Ethics Committees (HREC: 13300, HRE2019-0280, respectively). The evaluation of this innovative programme will provide the foundation for an Randomised Controlled Trial (RCT) and national roll-out, thus improving the quality of life of those who have been directly affected by breast cancer across Australia. Results will be published in peer-reviewed journals, presented at relevant conferences and disseminated to survivorship-focused organisations. TRIAL REGISTRATION NUMBER: Registered trial with the Australian New Zealand Clinical Trials Registry (ANZCTR) (ACTRN12618001985279); Pre-results.

The impact of stimulants on a clinical measure of attention in children with ADHD.

The effect of stimulant medication on the attentional functioning of 23 children (8-12 yrs) with attention deficit/hyperactivity disorder (ADHD) was investigated. Significant main effects of medication and TEA-Ch subtests were found, however there was no significant interaction. Planned contrasts showed that stimulants improved performance on the sustained attention, but not the selective or divided attention, subtests. Similar to previous studies, the results indicate that stimulants improve sustained attention in children with ADHD. Significant effects of stimulants on selective and divided attention, however, were not as apparent. Therefore, care must be taken when using TEA-Ch subtests to assess performance change subsequent to stimulant administration.

Progressive age-related changes in the attentional blink paradigm.

Previous studies on aging and attention typically examine group differences between younger and older adults, rather than seeing aging as a continuous process. Using correlational analyses, this study examined progressive changes in the magnitude of the attentional blink (AB) associated with aging. Increased age was found to be significantly associated with the ability to detect the second target (T2), whereby older age was correlated with the production of a longer and more pronounced AB; this supports the proposition that aging is associated with reduced inhibitory processes and selective attention. It was also found that AB performance somewhat improves between ages 18-39 years, but tends to decline from 40 years of age onward, providing an interesting and novel finding that AB effects may become more sensitive at this point in time. The AB task may prove useful in the assessment of selective attention in normal healthy adults, as well as changes associated with pathological aging.

Workplace road safety risk management: An investigation into Australian practices.

In Australia, more than 30% of the traffic volume can be attributed to work-related vehicles. Although work-related driver safety has been given increasing attention in the scientific literature, it is uncertain how well this knowledge has been translated into practice in industry. It is also unclear how current practice in industry can inform scientific knowledge. The aim of the research was to use a benchmarking tool developed by the National Road Safety Partnership Program to assess industry maturity in relation to risk management practices. A total of 83 managers from a range of small, medium and large organisations were recruited through the Victorian Work Authority. Semi-structured interviews aimed at eliciting information on current organisational practices, as well as policy and procedures around work-related driving were conducted and the data mapped onto the benchmarking tool. Overall, the results demonstrated varying levels of maturity of risk management practices across organisations, highlighting the need to build accountability within organisations, improve communication practices, improve journey management, reduce vehicle-related risk, improve driver competency through an effective workplace road safety management program and review organisational incident and infringement management. The findings of the study have important implications for industry and highlight the need to review current risk management practices.

A new approach to managing work-related road traffic injury: The development of a health investment framework.

OBJECTIVE: Statistics indicate that employees commuting or traveling as part of their work are overrepresented in workplace injury and death. Despite this, many organizations are unaware of the factors within their organizations that are likely to influence potential reductions in work-related road traffic injury. METHODS: This article presents a multilevel conceptual framework that identifies health investment as the central feature in reducing work-related road traffic injury. Within this framework, we explore factors operating at the individual driver, workgroup supervisor, and organizational senior management levels that create a mutually reinforcing system of safety. RESULTS: The health investment framework identifies key factors at the senior manager, supervisor, and driver levels to cultivating a safe working environment. These factors are high-performance workplace systems, leader-member exchange and autonomy, trust and empowerment, respectively. The framework demonstrates the important interactions between these factors and how they create a self-sustaining organizational safety system. CONCLUSIONS: The framework aims to provide insight into the future development of interventions that are strategically aligned with the organization and target elements that facilitate and enhance driver safety and ultimately reduce work-related road traffic injury and death.

Do management practices support or constrain safe driving behaviour? A multi-level investigation in a sample of occupational drivers.

It has been estimated that one-third of all work-related deaths occur while driving for work-related purposes. Despite this, many organisations are unaware of the practices, beyond those that identify and control the impact of unforeseen events (i.e., risk management), that predispose drivers to risk. This study addresses the issue by identifying the management practices operationalised as, High Performance Workplace Systems (HPWS) that influence safe driver behaviour. The study also explores the value given to safety by senior level management as a moderator of the relationship between HPWS practices and driver behaviour. Each factor was tested within a two level hierarchical model consisting of 911 drivers, nested within 161 supervisors and 83 organisations. The findings highight that under conditions of high investment in job and work design, communication and selection practices, drivers reported poorer driving behaviour. An interaction effect also demonstrated that under conditions of high investment in remuneration, drivers reported safer behaviour, but only when they perceived that managers valued and prioritised safety. The findings challenge current thinking in the management of workplace road safety.

Age-related differences in cognitive function using a global local hierarchical paradigm.

While research suggests that normal ageing is associated with compromised divided attentional processing abilities, such studies are comparatively few in comparison to other areas of attention (e.g. selective attention). The current study sought to examine age-related effects in divided attention using a global/local paradigm in three normal healthy age groups: younger adults (20-40 years), middle-aged (40-60 years), and older adults (61-80 years). In three experiments we sought to examine the ability to process local/global stimuli, ability to divide and switch attention, as well as the influence of a cue on target performance. Experiment 1 revealed global precedence and interference for all age groups; older adults were overall significantly slower in their response times. Experiments 2 and 3 suggest an age-related impairment in dividing and switching attention, which may begin as early as middle age. The findings are considered to reflect reduced inhibitory mechanisms, as well as possible neurobiological changes in the normal ageing process.

Cortical inhibition within motor and frontal regions in alcohol dependence post-detoxification: A pilot TMS-EEG study.

OBJECTIVES: Preclinical studies suggest that cortical alterations within the prefrontal cortex (PFC) are critical to the pathophysiology of alcohol dependence. Combined transcranial magnetic stimulation (TMS) and electroencephalography (EEG) allows direct assessment of cortical excitability and inhibition within the PFC of human subjects. We report the first application of TMS-EEG to measure these indices within the PFC of alcohol-dependent (ALD) patients post-detoxification. METHODS: Cortical inhibition was assessed in 12 ALD patients and 14 healthy controls through single and paired-pulse TMS paradigms. Long-interval cortical inhibition indexed cortical inhibition in the PFC. In the motor cortex (MC), short- interval intracortical inhibition and cortical silent period determined inhibition, while intracortical facilitation measured facilitation, resting and active motor threshold indexed cortical excitability. RESULTS: ALD patients demonstrated altered cortical inhibition across the bilateral frontal cortices relative to controls. There was evidence of altered cortical excitability in ALD patients; however, no significant differences in MC inhibition. CONCLUSIONS: Our study provides first direct evidence of reduced cortical inhibition in the PFC of ALD patients post-detoxification. Altered cortical excitability in the MC may reflect hyper-excitability within the cortex associated with chronic alcohol consumption. These findings provide initial neurophysiological evidence of disrupted cortical excitability within the PFC of ALD patients.

The interaction of shape- and location-based priming in object categorisation: evidence for a hybrid "what + where" representation stage.

The relationship between part shape and location is not well elucidated in current theories of object recognition. Here we investigated the role of shape and location of object parts on recognition, using a classification priming paradigm with novel 3D objects. In Experiment 1, the relative displacement of two parts comprising the prime gradually reduced the priming effect. In Experiment 2, presenting single-part primes in locations progressively different from those in the composite target had no effect on priming. In Experiment 3, manipulating the relative position of composite prime and target strongly affected priming. Finally, in Experiment 4 the relative displacement of single-part primes and composite targets did influence response time. Together, these findings are best interpreted in terms of a hybrid theory, according to which conjunctions of shape and location are explicitly represented at some stage of visual object processing.
