RESUMO

Health care workers experience high rates of burnout and psychiatric distress. A large health care system in the southwest United States developed a comprehensive mental health service model for employees. Services offered range from traditional benefits (eg, Employee Assistance Program), resiliency and well-being initiatives, and innovative technology solutions, to access to peer support services for professional practice issues. The latest innovation in services is a free, self-insured outpatient mental health clinic designed exclusively for health care workers and their dependents. In this article, the authors describe the development of expanded mental health programming for health care workers and discuss how this unique service model proactively reduces common barriers to the receipt of high-quality care. This approach to caring for the workforce may serve as a model for other health care organizations across the United States. By providing mental health support to employees, health care organizations are mitigating the risk of burnout and related consequences to the system.

RESUMO

The context of child prosthetics is a complex and important area for research and innovation. Yet, like many areas of paediatric medical technology development, there are several barriers to innovating specifically for the unique needs of children (i.e., a relatively small patient population or 'market'). As such, much child prosthetics technology is developed from the downsizing of adult prosthetics, leading to suboptimal outcomes for children and young people. Since 2016, the Starworks Child Prosthetics Research Network has been exploring this space, bringing children and their families together with key opinion leaders from the NHS, clinical Academia and leading National Research Centres with capabilities in child prosthetics with the aim of increasing research across the system. Above all else, Starworks is centred on the needs of children and their families, ensuring they have an equal voice in driving the ongoing research agenda. This article will share key learnings from the creation and development of the Starworks Network that may be applicable and/or adaptable across a wider paediatric medical technology research and innovation landscape. In particular it will discuss how it addressed three key aims of; (1) Addressing child-specific issues; (2) Building a sustainable network; and (3) Fostering impactful innovation.

RESUMO

The health care delivery system in the United States, structured to provide single-disease care, presents unique challenges for patients with complex physical and psychiatric comorbidities. Patients in these populations are often referred to multiple specialty clinics, encounter little continuity of care or collaboration among their providers, incur high health care costs, and experience poor treatment outcomes. Given these barriers, questions remain about the extent to which siloed and fragmented care, as opposed to the complex nature of the illnesses themselves, contribute to poor outcomes. If given the opportunity to receive well-integrated, consistent, and personalized care, can patients with historically difficult-to-treat comorbid medical and mental illnesses make progress? This article describes an innovative model of care called functional rehabilitation that is designed to address existing barriers in treatment. The functional rehabilitation program seeks to disrupt the escalating effects of interacting comorbidities by offering highly collaborative treatment from a small team of clinicians, personalized interventions using a shared decision-making framework, multipronged treatment options, colocation in a large hospital system, and significant 1:1 time with patients. The article includes a case example with longitudinal outcome data that illustrates how progress can be made with appropriate programmatic supports. Future research should examine the cost-effectiveness of this model of care.

RESUMO

Sedation is an essential component of treatment for some patients admitted to the ICU, but it carries a risk of sedation-related delirium. Sedation-related delirium is associated with higher mortality and increased length of stay, but pharmacologic treatments for delirium can lead to oversedation or other adverse effects. Therefore, nonpharmacologic treatments are recommended in the literature; however, these recommendations are quite general and do not provide structured interventions. To establish a structured nonpharmacologic intervention that could improve indications of delirium after sedation, we combined evidence-based interventions including recordings of sensory-rich stories told by the patient's family and patient-specific music into our novel positive stimulation for medically sedated patients (PSMSP) protocol. The positive listening stimulation playlist organized by a board-certified music therapist (MT-BC) within the PSMSP protocol can be used in carefully monitored sessions with the MT-BC potentially to decrease agitation and stabilize arousal, as well as being played by nursing staff throughout the patient's recovery from sedation. Further controlled studies will be necessary, but the PSMSP protocol has the potential to reduce agitation and increase arousal during listening, as highlighted by the case of a patient recovering from sedation during treatment for COVID-19 pneumonia. It is important for the entire critical care team to be aware of nonpharmacologic treatments like PSMSP that are available for delirium mitigation so that, where applicable, these therapies can be incorporated into the patient's treatment regimen.

RESUMO

BACKGROUND: Changes in residuum volume are a common problem in lower-limb amputees during prosthesis usage, and can lead to poor suspension, impaired gait, and tissue damage. Residuum volume can be affected by the in-socket air pressure, which will influence fluid flow in and around the residuum. The use of "active" pumps to reduce air pressure has been shown to conserve the residuum volume, but these are expensive and unlikely to be widely available. An alternative, passive approach, based on Boyles' law, is to introduce a larger distal void volume at the end of the socket and hence reduce the change in pressure for a given change in volume. OBJECTIVES: To compare the performance across three test conditions (passive-conventional, with standard distal void; passive-with increased distal void; and active system) in terms of residuum volume changes and comfort. STUDY DESIGN: Repeated-measures experiment under three test conditions. METHODS: Five transtibial amputee participants (three males and two females), aged between 27 and 67 years, and of mobility grade K2 or K3, were fitted with a bespoke test prosthesis that was adapted to include the three test conditions. Residuum volume was measured before and after walking under each test condition (presented in a random order). Comfort was also assessed after walking with each test condition. RESULTS: The reduction in residuum volume, relative to the baseline volume, was higher for the conventional passive system (4.2% ± 2.8%) compared with the modified passive (1.4% ± 1.4%) and active (1.6% ± 1.1%) systems. CONCLUSION: The use of a passive suspension system with an increased distal void within the socket may help to stabilize the residuum volume during prosthesis usage.

RESUMO

To enable the progression of research during the COVID-19 lockdown, a novel remote method of creating clinical standard trans-radial bypass sockets was devised as a collaboration between an engineering team and a clinical research group. The engineering team recruited two able-bodied participants, marked areas of interest on the participant's limb and captured limb geometry and electrode sites with a high definition optical scanner. The resulting 3D scan was modified to make electrode sites and areas of interest recessed and tactile. Models were 3D printed to scale and posted to the clinical team to manufacture the sockets. A modified lamination process was used, comprising plaster casting and rectifiying the model by hand. The recessed areas of the 3D printed model were used to guide the process. The bypass sockets were returned to the engineering team for testing. A simple electromyography (EMG) tracking task was performed using clinical electrodes to validate the skin-electrode contact and alignment. This paper demonstrates a validated method for remotely creating transradial bypass sockets. There is potential to extrapolate this method to standard socket fittings with further research.

RESUMO

BACKGROUND: Achilles tendinopathy (AT) is common, and can be traumatic or insidious in onset and short-lasting or persistent in nature. Factors influencing the experience of pain are poorly understood; little is known about mechanisms driving pain and the response (or lack of) to rehabilitation. Despite this, there is a growing body of evidence supporting the use of exercise to manage AT. Interestingly, variation in exercise approach does not appear to significantly impact outcome. Patients' perceptions of factors related to rehabilitation that may influence outcome could provide a valuable addition to help guide future research and practice. OBJECTIVES: The aim of this study is to gain an insight into patients' experiences of participating in an exercise-based rehabilitation programme for AT. METHOD: A qualitative interpretive description design. Data generated from semi-structured interviews were analysed thematically using the guidelines set out by Braun and Clarke. FINDINGS: This is the first study to use a qualitative method of inquiry to gain data on the experiences of people undertaking exercise-based rehabilitation for AT. The four major themes that were identified from the data were: (1) 'understanding the impact' (2) 'expectations' (3) 'what matters' and (4) 'the burden of exercise'. CONCLUSIONS: Given the uncertainty surrounding the mechanisms of effect of our treatments, the insights provide a platform from which researchers and clinicians can consider further in the management of people with Achilles tendinopathy. Specifically, it has highlighted that patients value a flexible, supportive approach embracing the biopsychosocial impact of AT on the individual.

RESUMO

As the demand for telepsychiatry increases during the COVID-19 pandemic, the strengths and challenges of telepsychiatry implementation must be articulated to improve clinical practices in the long term. Currently, observations within US contexts are lacking; therefore, we report on the rapid implementation of telepsychiatry and workflow experiences in a psychiatric practice based within a large health care system in southeast Texas with a national catchment area. We discuss the logistics of the implementation, including modes of communication, scheduling, coordination, and capacity; the psychological effects of web-based services, including both the loss of the physical therapeutic environment and the unique interpersonal dynamics experienced in the virtual environment; and postadoption patterns of engagement with our services and with other clinical functions affected by the rapid adaptation to telemedicine. Our art therapy group programming serves as an applied case study, demonstrating the value of a well-managed web-based program (eg, patients were receptive and well-engaged, and they appreciated the continuity of accessible service) as well as the challenges (eg, the need for backup plans and technological fallbacks, managing interruptions and telecommunication learning curves, and working around the difference in resources for art and music therapy between a well-stocked clinical setting versus clients' home spaces). We conclude from our experience that the overall strengths of telepsychiatry include receptive and well-engaged responses from patients as well as the expansion of boundaries, which provides a directly contextualized view into patients' home lives. Challenges and corresponding recommendations include the need for more careful safety planning for high-risk patients; maintaining professional boundaries in the newly informal virtual setting; designing the physical space to both frame the patient encounter and maintain work-life balance for the therapist; allowing for delays and interruptions (including an initial acclimation session); and preserving interprofessional care team collaboration when the physical locations that normally facilitate such encounters are not accessible. We believe that careful observations of the strengths and challenges of telepsychiatry during this pandemic will better inform practices that are considering telepsychiatry adoption both within pandemic contexts and more broadly thereafter.

RESUMO

Using a shoulder harness and control cable, a person can control the opening and closing of a body-powered prosthesis prehensor. In many setups the cable does not pass adjacent to the shoulder joint center allowing shoulder flexion on the prosthetic side to be used for prehensor control. However, this makes cable setup a difficult compromise as prosthesis control is dependent on arm posture; too short and the space within which a person can reach may be unduly restricted, too long and the user may not be able to move their shoulder sufficiently to take up the inevitable slack at some postures and hence have no control over prehensor movement. Despite the fundamental importance of reachable workspace to users, to date there have been no studies in prosthetics on this aspect. Here, a methodology is presented to quantify the reduction in the reachable volume due to the harness, and to record the range-of-motion of the prehensor at a series of locations within the reachable workspace. Ten anatomically intact participants were assessed using a body-powered prosthesis simulator. Data was collected using a 3D motion capture system and an electronic goniometer. The harnessed reachable workspace was 38-85% the size of the unharnessed volume with participants struggling to reach across the body and above the head. Across all arm postures assessed, participants were only able to achieve full prehensor range-of-motion in 9%. The methodologies presented could be used to evaluate future designs of both body-powered and myoelectric prostheses.

RESUMO

Purpose: The ageing process can be accompanied by a degeneration of the spine and increase the risk of thoracic hyperkyphosis (excessive spinal forward curvature) amongst elderly people. This condition can in turn impair mobility, reduce balance, and increase the risk of falling and mortality in affected individuals. The use of corrective orthotic bracing has been shown to improve spinal posture, and increase stability and balance amongst the elderly. However, there is little evidence that evaluates the use of corrective braces on foot pressure changes in these subjects.Methods: In this study, we evaluated the use of a thoracolumbosacral orthosis (TLSO) on 19 subjects over 60 years old who presented with hyperkyphosis. We measured foot pressure using the Pedar-X system before (without brace) and after (with brace) immediate using a TLSO in both static (quite standing) and dynamic (walking on a 5 meters freeway) scenarios.Results: The results demonstrated that using a TLSO immediately decreases forefoot pressures in stasis, and around the first metatarsal, as well as pressures relating to the second to fifth metatarsals under dynamic conditions. Hindfoot pressures were increased, but not significantly.Conclusion: This study showed that using a TLSO can be beneficial for elderly people with hyperkyphosis.Implications for rehabilitationThe ageing process can be accompanied by a degeneration of the spine and increase the risk of thoracic hyperkyphosis.The use of corrective orthotic bracing has been shown to improve spinal posture, and increase stability and balance amongst the elderly.Using a TLSO decreases forefoot pressures in stasis, and around the first metatarsal, as well as pressures relating to the second to fifth metatarsals under dynamic conditions.

RESUMO

OBJECTIVE: Achilles tendinopathy is a common type of overuse condition, with isolated eccentric loading (ECL) programmes being the principal conservative treatment of choice. However, alternative protocols, involving different contraction types, have more recently been investigated. The purpose of the present review was to examine the evidence from studies comparing two or more different types of loading programmes in relation to patient-reported outcomes for people with Achilles tendinopathy. METHODS: A systematic review was undertaken, and the risk of bias of included papers were assessed using the Cochrane Risk of Bias tool. An electronic search of CINAHL, MEDLINE, Embase and SPORTDiscus was undertaken from their inception to May 2018. The eligibility criteria for selecting studies were randomized controlled or clinical controlled trials investigating two or more different loading programmes for chronic (>3 months) Achilles tendinopathy. RESULTS: Seven articles were included in the review. Low-quality evidence exists that a do-as-tolerated modification of the Alfredson programme is more effective than the standardized programme at improving function in the short term. Very-low-quality evidence suggests that ECL is superior at reducing pain levels than concentric in isolation, but no more effective at improving pain or disability than concentric-eccentric programmes. CONCLUSIONS: There is conflicting evidence regarding the superiority of ECL over other contraction types, challenging the current approach to managing Achilles tendinopathy. There is also evidence that do-as-tolerated repetition volumes are more effective at improving function in the short term compared with those recommended by the standardized Alfredson protocol.

RESUMO

The upper limb activity of twenty unilateral upper limb myoelectric prosthesis users and twenty anatomically intact adults were recorded over a 7-day period using two wrist worn accelerometers (Actigraph, LLC). This dataset reflects the real-world activities of the participants during their normal day-to-day routines. Participants included students, working adults, and retirees recruited from across the United Kingdom. This dataset offers a potential wealth of knowledge into a poorly understood cohort. The raw unprocessed data files and the activity count data exported from the Actilife software are provided. We also provide a non-wear algorithm developed for the removal of prosthesis non-wear periods and resulting activity count data corresponding to prothesis wear periods. Finally, we have included the transposed activity diaries provided by the participants. Analysis to date has primarily involved assessment of the symmetry of upper limb activity, however, there is potential to undertake additional analysis such as understanding the differences in the way a prosthesis is used compared to an anatomical arm.

RESUMO

Four compounds (1-4) were isolated from a Hawaiian sponge of the genus Myrmekioderma. Myrmenaphthol A (1) incorporates two unusual elements into an oxidized steroidal core: a naphthyl AB-ring system and a hydroxy group at C-2. A comparison of the experimental and predicted electronic circular dichroism (ECD) spectra of 1 assigned an S configuration to the lone stereocenter (ΔESI = 0.75; similarity factor 0.8137). Known compounds, cinanthrenol A (2), 3,4-dihydroxypregna-5,17-diene-10,2-carbolactone (3), and 3,4-dihydroxypregna-5,20-diene-10,2-carbolactone (4), were also isolated. Despite literature reports of competitive inhibition at nanomolar levels for 2, neither 2 nor the structurally related 1 showed any activity against estrogen receptors at the concentrations tested.

RESUMO

Several known sesquiterpenoid quinones and quinols (1-9), and kauamide (10), a new polyketide-peptide containing an 11-membered heterocycle, were isolated from the extracts of the Hawaiian marine sponge Dactylospongia elegans. The planar structure of 10 was determined from spectroscopic analyses, and its relative and absolute configurations were established from density functional theory (DFT) calculations of the GIAO NMR shielding tensors, and advanced Marfey's analysis of the N-MeLeu residue, respectively. Compounds 1 and 3 showed moderate inhibition of ß-secretase 1 (BACE1), whereas 1-9 exhibited moderate to potent inhibition of growth of human glioma (U251) cells. Compounds 1-2 and 4-7 were also active against human pancreatic carcinoma (Panc-1) cells.

RESUMO

The "uncanny phenomenon" describes the feeling of unease associated with seeing an image that is close to appearing human. Prosthetic hands in particular are well known to induce this effect. Little is known, however, about this phenomenon from the viewpoint of prosthesis users. We studied perceptions of eeriness and human-likeness for images of different types of mechanical, cosmetic, and anatomic hands in upper-limb prosthesis users (n=9), lower-limb prosthesis users (n=10), prosthetists (n=16), control participants with no prosthetic training (n=20), and control participants who were trained to use a myoelectric prosthetic hand simulator (n=23). Both the upper- and lower-limb prosthesis user groups showed a reduced uncanny phenomenon (i.e., significantly lower levels of eeriness) for cosmetic prosthetic hands compared to the other groups, with no concomitant reduction in how these stimuli were rated in terms of human-likeness. However, a similar effect was found neither for prosthetists with prolonged visual experience of prosthetic hands nor for the group with short-term training with the simulator. These findings in the prosthesis users therefore seem likely to be related to limb absence or prolonged experience with prostheses.

RESUMO

BACKGROUND: The aim of this study was to assess the performance of an original powered foot clearance creator (PFCC) mechanism worn in conjunction with an isocentric reciprocal gait orthosis (IRGO) and evaluate its effect on trunk compensatory movements and spatiotemporal parameters in nine healthy subjects. METHOD: A PFCC motorized mechanism was designed that incorporated twin sole plates, the movements of which enabled increased toe to floor clearance during swing phase. A prototype was constructed in combination with an IRGO, and hence was re-named as an IRGO-PFCC orthosis. The effects of IRGO-PFCC usage on the spatiotemporal parameters and trunk compensatory movements during walking were then analyzed under two conditions, firstly with the PFCC 'active' i.e., with the motorized device functioning, and secondly inactive, where floor clearance was standard. RESULTS: Ambulating with IRGO-PFCC orthosis resulted in reduction in the spatiotemporal parameters of gait (speed of walking, cadence and stride length) in nine healthy subjects. Walking with IRGO-PFCC orthosis led to significant differences in lateral (p = .007) and vertical (p = .008) trunk compensatory movements. In other words, through using IRGO-PFCC orthosis, the lateral and vertical trunk compensatory movements decreased by 51.32% and 42.7%, respectively. CONCLUSION: An adapted PFCC mechanism, with a relatively small motor and power supply could effectively increase toe to floor clearance during swing phase and thereby decrease trunk compensatory motions and potentially improve energy consumption. Implications for rehabilitations •The High rejection rates of reciprocal gait orthoses are related to the increasing in energy expenditure and burden loads on the upper limb joints during walking following trunk compensatory movements.•An original powered foot clearance creator mechanism was designed and constructed to assisting floor clearance capability and reduce trunk compensatory movements in subjects with spinal cord injury during swing phase of gait.•This original powered foot clearance creator mechanism by using moveable soleplates and motorized actuation could decrease the trunk compensatory motions during the ambulation of nine healthy subjects.•More experiments are needed to investigate this mechanism on trunk compensatory movements of SCI subjects.

RESUMO

STUDY DESIGN: Pilot study. PURPOSE: Evaluation of two different hip-knee-ankle-foot orthoses (HKAFOs; medial linkage reciprocating gait orthosis [MLRGO] and isocentric reciprocating gait orthosis [IRGO]) using gait and postural stability analysis in four subjects with spinal cord injury (SCI). OVERVIEW OF LITERATURE: To the best of our knowledge, no study has evaluated postural stability in subjects with SCI when using MLRGO and IRGO. METHODS: The relative efficacy of each orthosis was evaluated with relevant gait parameters, and an assessment of postural stability and sway during usage was made. Each analysis was conducted following an appropriate period of training and acclimatization. The gait parameters employed in the study were walking speed, cadence, and endurance; these were recorded and analyzed using current, validated methods. Postural stability was assessed using a verified force plate measurement system, and a modified Falls Efficacy Scale (mFES) was used for the measurement of postural sway and the perceived fear of falling. RESULTS: Walking speed, cadence, and endurance increased with the use of both HKAFOs. When the two types of HKAFOs were compared, all the parameters showed a slight (but not significant) increase with the use of MLRGO compared with the use of IRGO. In contrast, there were slight but insignificant improvements in postural sway with the use of IRGO. However, although there were no significant differences between the two sets of mFES scores, there was a slightly reduced fear of falling with the use of MLRGO compared with the use of IRGO in the static standing position. CONCLUSIONS: It is noteworthy that meaningful interpretations of results can only be drawn if a larger sample is employed. This pilot study showed no significant data; however, the results indicate that the use of MLRGO is superior to that of IRGO in terms of potential improvement in the mobility and confidence levels of subjects with SCI.

RESUMO

BACKGROUND: Current outcome measures used in upper limb myoelectric prosthesis studies include clinical tests of function and self-report questionnaires on real-world prosthesis use. Research in other cohorts has questioned both the validity of self-report as an activity assessment tool and the relationship between clinical functionality and real-world upper limb activity. Previously,1 we reported the first results of monitoring upper limb prosthesis use. However, the data visualisation technique used was limited in scope. STUDY DESIGN: Methodology development. OBJECTIVES: To introduce two new methods for the analysis and display of upper limb activity monitoring data and to demonstrate the potential value of the approach with example real-world data. METHODS: Upper limb activity monitors, worn on each wrist, recorded data on two anatomically intact participants and two prosthesis users over 1 week. Participants also filled in a diary to record upper limb activity. Data visualisation was carried out using histograms, and Archimedean spirals to illustrate temporal patterns of upper limb activity. RESULTS: Anatomically intact participants' activity was largely bilateral in nature, interspersed with frequent bursts of unilateral activity of each arm. At times when the prosthesis was worn prosthesis users showed very little unilateral use of the prosthesis (≈20-40 min/week compared to ≈350 min/week unilateral activity on each arm for anatomically intact participants), with consistent bias towards the intact arm throughout. The Archimedean spiral plots illustrated participant-specific patterns of non-use in prosthesis users. CONCLUSION: The data visualisation techniques allow detailed and objective assessment of temporal patterns in the upper limb activity of prosthesis users. Clinical relevance Activity monitoring offers an objective method for the assessment of upper limb prosthesis users' (PUs) activity outside of the clinic. By plotting data using Archimedean spirals, it is possible to visualise, in detail, the temporal patterns of upper limb activity. Further work is needed to explore the relationship between traditional functional outcome measures and real-world prosthesis activity.
