Walking on common ground: a cross-disciplinary scoping review on the clinical utility of digital mobility outcomes. NPJ Digit Med 2021; 4:149. [PMID: 34650191 PMCID: PMC8516969 DOI: 10.1038/s41746-021-00513-5] [Citation(s) in RCA: 32] [Impact Index Per Article: 10.7] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2021] [Accepted: 08/09/2021] [Indexed: 02/08/2023] Open
Abstract
Physical mobility is essential to health, and patients often rate it as a high-priority clinical outcome. Digital mobility outcomes (DMOs), such as real-world gait speed or step count, show promise as clinical measures in many medical conditions. However, current research is nascent and fragmented by discipline. This scoping review maps existing evidence on the clinical utility of DMOs, identifying commonalities across traditional disciplinary divides. In November 2019, 11 databases were searched for records investigating the validity and responsiveness of 34 DMOs in four diverse medical conditions (Parkinson's disease, multiple sclerosis, chronic obstructive pulmonary disease, hip fracture). Searches yielded 19,672 unique records. After screening, 855 records representing 775 studies were included and charted in systematic maps. Studies frequently investigated gait speed (70.4% of studies), step length (30.7%), cadence (21.4%), and daily step count (20.7%). They studied differences between healthy and pathological gait (36.4%), associations between DMOs and clinical measures (48.8%) or outcomes (4.3%), and responsiveness to interventions (26.8%). Gait speed, step length, cadence, step time and step count exhibited consistent evidence of validity and responsiveness in multiple conditions, although the evidence was inconsistent or lacking for other DMOs. If DMOs are to be adopted as mainstream tools, further work is needed to establish their predictive validity, responsiveness, and ecological validity. Cross-disciplinary efforts to align methodology and validate DMOs may facilitate their adoption into clinical practice.

Abstract
OBJECTIVES To assess the experience of people with long-term respiratory conditions regarding the impact of measures to reduce risk of COVID-19. DESIGN Analysis of data (n=9515) from the Asthma UK and British Lung Foundation partnership COVID-19 survey collected online between 1 and 8 April 2020. SETTING Community. PARTICIPANTS 9515 people with self-reported long-term respiratory conditions. 81% female, age ranges from ≤17 years to 80 years and above, from all nations of the UK. Long-term respiratory conditions reported included asthma (83%), chronic obstructive pulmonary disease (10%), bronchiectasis (4%), interstitial lung disease (2%) and 'other' (<1%) (eg, lung cancer and pulmonary endometriosis). OUTCOME MEASURES Study responses related to impacts on key elements of healthcare, as well as practical, psychological and social consequences related to the COVID-19 pandemic and social distancing measures. RESULTS 45% reported disruptions to care, including cancellations of appointments, investigations, pulmonary rehabilitation, treatment and monitoring. Other practical impacts such as difficulty accessing healthcare services for other issues and getting basic necessities such as food were also common. 36% did not use online prescriptions, and 54% had not accessed online inhaler technique videos. Psychosocial impacts including anxiety, loneliness and concerns about personal health and family were prevalent. 81% reported engaging in physical activity. Among the 11% who were smokers, 48% reported they were planning to quit smoking because of COVID-19. CONCLUSIONS COVID-19 and related social distancing measures are having profound impacts on people with chronic respiratory conditions. Urgent adaptation and signposting of services is required to mitigate the negative health consequences of the COVID-19 response for this group.

Walking-related digital mobility outcomes as clinical trial endpoint measures: protocol for a scoping review. BMJ Open 2020; 10:e038704. [PMID: 32690539 PMCID: PMC7371223 DOI: 10.1136/bmjopen-2020-038704] [Citation(s) in RCA: 24] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/20/2020] [Revised: 05/14/2020] [Accepted: 05/18/2020] [Indexed: 02/06/2023] Open
Abstract
INTRODUCTION Advances in wearable sensor technology now enable frequent, objective monitoring of real-world walking. Walking-related digital mobility outcomes (DMOs), such as real-world walking speed, have the potential to be more sensitive to mobility changes than traditional clinical assessments. However, it is not yet clear which DMOs are most suitable for formal validation. In this review, we will explore the evidence on discriminant ability, construct validity, prognostic value and responsiveness of walking-related DMOs in four disease areas: Parkinson's disease, multiple sclerosis, chronic obstructive pulmonary disease and proximal femoral fracture. METHODS AND ANALYSIS Arksey and O'Malley's methodological framework for scoping reviews will guide study conduct. We will search seven databases (Medline, CINAHL, Scopus, Web of Science, EMBASE, IEEE Digital Library and Cochrane Library) and grey literature for studies which (1) measure differences in DMOs between healthy and pathological walking, (2) assess relationships between DMOs and traditional clinical measures, (3) assess the prognostic value of DMOs and (4) use DMOs as endpoints in interventional clinical trials. Two reviewers will screen each abstract and full-text manuscript according to predefined eligibility criteria. We will then chart extracted data, map the literature, perform a narrative synthesis and identify gaps. ETHICS AND DISSEMINATION As this review is limited to publicly available materials, it does not require ethical approval. This work is part of Mobilise-D, an Innovative Medicines Initiative Joint Undertaking which aims to deliver, validate and obtain regulatory approval for DMOs. Results will be shared with the scientific community and general public in cooperation with the Mobilise-D communication team. REGISTRATION Study materials and updates will be made available through the Center for Open Science's OSFRegistry (https://osf.io/k7395).

Work participation, mobility and foot symptoms in people with systemic lupus erythematosus: findings of a UK national survey. J Foot Ankle Res 2019; 12:26. [PMID: 31164925 PMCID: PMC6489339 DOI: 10.1186/s13047-019-0335-0] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/01/2019] [Accepted: 04/11/2019] [Indexed: 11/12/2022] Open
Abstract
Objective The aim of this study was to investigate whether foot and lower limb related symptoms were associated with work participation and poor mobility in people with Systemic Lupus Erythematosus (SLE). Method A quantitative, cross-sectional, self-reported survey design was utilised. People with SLE from six United Kingdom (UK) treatment centres and a national register were invited to complete a survey about lower limb and foot health, work participation and mobility. Data collected included work status and the prevalence of foot symptoms. The focus of the analyses was to explore potential associations between poor foot health work non-participation. Results In total, 182 useable surveys were returned. Seventy-nine respondents reported themselves as employed and 32 reported work non-participation. The remaining were retired due to age or reported work non-participation for other reasons. Work non-participation due to foot symptoms was significantly associated with difficulty walking (p = 0.024), past episodes of foot swelling (p = 0.041), and past episodes of foot ulceration (p = 0.018). There was a significant increase in foot disability scores amongst those not working (mean 18.13, 95% CI: 14.85–21.41) compared to those employed (mean 10.16, 95% CI: 8.11–12.21). Conclusions Twenty-nine% of people with SLE reported work non-participation because of lower limb or foot problems. Our results suggest that foot health and mobility may be important contributors to a persons’ ability to remain in work and should be considered as part of a clinical assessment.

Abstract
Background Systemic lupus erythematosus (SLE) can present with a variety of symptoms. Previous research has shown there is a high prevalence of lower limb and foot problems in patients with SLE associated with the musculoskeletal, vascular and neurological changes. Furthermore, there is a high prevalence of infections affecting the feet and a range of common skin and nail problems. However, it is not known how these foot problems impact upon people’s lives. Therefore, we aimed to explore this using a qualitative approach. Method Following ethical approval, 12 participants were recruited who had a diagnosis of SLE, current and/or past experience of foot problems and were over 18 years in age. Following consent, interviews were carried out with an interpretivist phenomenological approach to both data collection and analysis. Results Seven themes provide insight into: foot problems and symptoms; the impact of these foot problems and symptoms on activities; disclosure and diagnosis of foot problems; treatment of foot problems and symptoms; perceived barriers to professional footcare; unanswered questions about feet and footcare; and identification of the need for professional footcare and footcare advice. Conclusion These participants tend to “self-treat” rather than disclose that they may need professional footcare. A lack of focus upon foot health within a medical consultation is attributed to the participant’s belief that it is not within the doctor’s role, even though it is noted to contribute to reduced daily activity. There is a need for feet to be included as a part of patient monitoring and for foot health management to be made accessible for people with SLE.

Abstract
Objective The main aim of this survey was to determine the frequency of self-reported lower limb or foot and ankle complications experienced by participants with systemic lupus erythematosus (SLE). A secondary aim was to determine the frequency of treatments that have been received or that participants with SLE may like to receive if offered. Method A quantitative, cross-sectional, self-reported survey design was utilized. The developed survey was checked for face and content validity prior to patient partner cognitive debriefing in order to ensure usability, understanding of the process of completion and of the questions posed. The full protocol for survey development has been published previously. Results This is the first comprehensive national UK survey of lower limb and foot health problems reported by participants with SLE. A high prevalence of vascular, dermatological and musculoskeletal complications was reported by survey respondents. Additionally, whilst the relative prevalence of sensory loss was low, a quarter of people reported having had a fall related to changes in foot sensation demonstrating a previously unknown rate and cause of falls. Conclusion Complications related to vascular, dermatological and musculoskeletal health are identified as particularly prevalent in participants with SLE. Further, there is a suggestion that the provision of interventions to maintain lower limb health is highly varied and lacks national standardization, despite there being a strong indication of participant reported need. The findings of this work can be used to inform care guideline development in addition to identifying areas for future research.

Effect of Mold Temperature on High-resilience Cold-cure Flexible Polyurethane Foam Surface Texture. J CELL PLAST 2016.

Abstract
Flexible polyurethane foam is often molded directly into preheated tools for foaming reaction which expands to fill the mold cavity. The foam that is directly in contact with the mold surface cures as the foam skin. Parts frequently have surface defects ranging from shrink marks, to voids, to mottling, and knit lines. There are many possible causes such as applying too much or too little release agent, or mold surface not cleaned and conditioned as required before the foaming process. Uneven mold temperatures are also suspected to be a cause of surface defects, especially in high-resilience (HR) cold-cure polyurethane foam systems. A specially designed mold capable of maintaining tight temperature tolerance is built to produce foam samples at varying temperatures. The effects of mold surface temperature on the foam surface texture are studied and analyzed. The effect of processing temperature on the macro and micro surface texture is examined. It is shown that the processing temperature has a significant effect on the foam surface texture. Three-dimensional topographical analysis of foam surface texture has discovered a trend from samples produced at varying temperatures from 30 to 80 C. This research is funded by EPSRC and assisted by Collins and Aikman UK, and Rojac Tooling Technologies Ltd.

Abstract
Polyurethane (PU) foam is molded into preheated tools and expands to fill the mold cavity. Foam parts frequently have defects such as varying density and flaws in surface texture. Although there are many possible causes uneven mold temperatures are suspected to be a leading cause of defects(1,2). Much of the work previously undertaken to reduce flexible foam molding scrap and improved quality has focused on chemical compositions, chemical reactions and materials development. This research is to investigate the effects of mold temperature on high-resilience cold-cure polyurethane foam molded parts. A specially designed airtight mold capable of holding tight temperature tolerance was used to produce standard size foam specimens at varying temperatures ranging from 30 °C to 80 °C. The specimens were kept in a controlled temperature and humidity environment for a stipulated time before analysis. The effect of mold temperature on the average foam density, density gradients and surface texture were measured. The foam specimens were weighed and measured for the overall density while Computerized Tomography was used to examine the density gradients throughout each foam specimen. 3D topographical analysis of the foam surface structure was conducted using a non-contact laser triangulation gauge. The results show that the mold temperature has an effect on the foam density and foam surface texture with specimens produced at 50 °C having the ideal texture.

Abstract
PURPOSE OF REVIEW To review the medical literature on neuromuscular abnormalities acquired in the intensive care unit (ICU), particularly after mechanical ventilation, focusing on the most recent advances in this field. RECENT FINDING Using a simple bedside muscle strength score, significant clinical weakness is detected in one fourth of patients awakening in ICU after more than 1 week of mechanical ventilation. Weakness is associated with a longer time on mechanical ventilation, although the exact relationship between limb and respiratory neuromuscular involvement remains unclear. Muscle involvement is often combined with axonal involvement and can predominate or occur in isolation in some patients. Although prolonged severe weakness is unusual, milder abnormalities may persist for several months after discharge. In addition to severity and duration of initial organ failures, both neuromuscular inactivity and use of corticosteroids make an independent contribution of the neuromuscular abnormalities. Conversely, strict glycemic control may prevent neuromuscular abnormalities, although this needs to be confirmed in general ICU patients. SUMMARY Avoiding complete neuromuscular inactivity, using corticosteroids with greater discernment, and closely monitoring blood glucose levels might be worthwhile avenues for research in prevention of neuromuscular abnormalities acquired in the most severely ill ICU patients. Investigations of the severity of the respiratory neuromuscular involvement are also warranted.

Abstract
It is unknown whether changes in corticomotor excitability follow exercise in healthy humans. We hypothesized that a fall in the diaphragm and quadriceps motor-evoked potential (MEP) amplitude elicited by transcranial magnetic stimulation of the motor cortex would occur after an incremental exercise task. In 11 healthy subjects, we measured transdiaphragmatic pressure and isometric quadriceps tension in response to supramaximal peripheral magnetic nerve stimulation. MEPs were recorded from these muscles in response to transcranial magnetic stimulation. After baseline measurements, subjects performed a period of submaximal exercise (gentle walking). Measurements were repeated 5 and 20 min after this. The subjects then exercised on a treadmill with an incremental protocol to exhaustion. Transcranial magnetic stimulation was performed at baseline and at 5, 20, 40, and 60 min after exhaustive exercise, and force measurements were obtained at baseline, 20 min, and 60 min. Mean exercise duration was 18 +/- 4 min, and mean maximum heart rate was 172 +/- 10 beats/min. Twitch transdiaphragmatic pressure and twitch isometric quadriceps tension were not different from baseline after exercise, but a significant decrease was observed in diaphragm MEP amplitude 5 and 20 min after exercise (60 +/- 38 and 45 +/- 24%, respectively, of baseline, P = 0.0001). At the same times, the mean quadriceps MEPs were 59 +/- 39 and 74 +/- 32% of baseline (P < 0.0001 and P < 0.01, respectively). Studies using paired stimuli confirmed a likely intracortical mechanism for this depression. Our data confirm significant depression of both diaphragm and quadriceps MEPs after incremental treadmill exercise.

Abstract
We studied the spectrum of septic discitis presenting to two busy district general hospitals over 2.5 years (November 1996 to April 1999), surveying the case notes of all patients attending Royal Bournemouth and Poole Hospitals with probable septic discitis on magnetic resonance imaging (MRI). Twenty-two cases of septic discitis were identified, suggesting an annual incidence of 2/100 000/year. Seventy-three percent of patients were aged > or =65 years. In 91% of patients, back pain was the presenting symptom, with neurological signs evident in 45% of patients. Fever >37.5 degrees C was present in 68% of patients, and a marked elevation of erythrocyte sedimentation rate (ESR) in 91%. Diagnosis was originally by MRI in 86% of patients, with plain radiographs not diagnostic of discitis in the early stages of the infection. Staphylococcus aureus was the commonest pathogen (41%), but in 18% of patients, no organism was identified. The major predisposing factors to septic discitis were invasive procedures (41%), underlying cancer (25%) and diabetes (18%). Pre-existing degenerative spinal disease was found in 50% of patients. Four patients whose causative organism was not isolated had a poorer outcome: one death and three with increased morbidity. Our estimated incidence rate (2/100 000/year) is higher than that in previous studies and may be due to a higher detection rate with MRI and/or a genuine increase in the number of cases. Septic discitis should be considered in any patient who has severe localized pain at any spinal level, especially if accompanied by fever and elevated ESR, or in the immunosuppressed.

Abstract
Lymphopenia is a common finding in old people admitted to medical and psychiatric wards. We describe a pilot study of the clinical associations, and prognostic significance of lymphopenia in elderly persons admitted to acute medical and psychiatric wards. Consecutive patients admitted to acute medical and psychiatric wards were prospectively selected according to initial peripheral lymphocyte count (PLC) into lymphopenic (PLC < 1.0 X 10(9)/litre, n = 41), and non-lymphopenic (PLC > 1.5 x 10(9)/litre, n = 23). Results of routine haematological and biochemical investigations were recorded, as well as drug history and medical diagnoses. Anthropometric measurements, assessment of functional ability (Barthel ADL Index), and cognitive function (Mini-Mental State Examination) were then performed by investigators blind to lymphocyte status. Patients were contacted between 3 and 6 months following recruitment into the study. Lymphopenia was associated with functional ability as measured by a lower Barthel score (p = 0.004), and cognitive impairment as measured by the Mini-Mental State Examination (p = 0.02). No association was found with medical diagnostic groupings, drugs known to cause lymphopenia, nutritional status, or survival. Lymphopenia may be a significant marker of vulnerability, and a larger study is required to elucidate the veracity and mechanisms of lymphopenia-associated debility.

Abstract
Multiple myeloma, relapsing polychondritis and myelodysplastic syndrome are all serious diseases in which making a clear diagnosis can be difficult. This case of a 72-year-old man found after extensive investigation to have all three of the above, demonstrates how difficult diagnosis and treatment can be, producing in this case a life threatening clinical syndrome. We also postulate that the association of these three diseases may be an immune-derived complication of myelodysplastic syndrome.

Abstract
A working party was established by the Population Screening Project Board (UK), in conjunction with the Family Health Services Computer Unit, in order to develop a system for diabetes care (DIALOG) that would create a District Diabetes Register and prompt the process of diabetes annual review across both primary and secondary care. To simplify the creation and maintenance of the Diabetes Register, DIALOG has been designed to interface with the Family Health Services Authority population register to enable realtime download of demographic data. The system will also accumulate clinical information for the continuing audit diabetes services according to the data items specified in the standard UK diabetes dataset and can deliver detailed statistical analyses. Data input can be manual or electronic. DIALOG has been created to complement and integrate with existing diabetes information systems in primary and secondary care; it is not intended to be a clinic management system. It has the potential to become a National Diabetes Register.

Abstract
Capillary vessel wall thickening may contribute to the muscle fibre atrophy and impaired pulmonary gas transfer notable in SLE/MCTD. Using electron microscopy we measured the thickness of unilaminar capillary basement membranes (CBM) and quantified basement membrane laminae and pericyte layers in the skeletal muscle biopsies of 31 patients with SLE, including 14 with MCTD, and 11 controls. Capillary basement membrane thickness was significantly increased in SLE compared with controls (P < 0.01) and was significantly associated with the level of C3dg (P < 0.01). Patients with MCTD had significantly greater layering of pericytes and laminae compared with patients with SLE alone (P < 0.0001 for both variables). Multiple stepwise regression analysis indicated that ANA titre was a good predictor of pericyte layering (R = 0.63, P = 0.003) and of basement membrane lamination (P < 0.0001), with steroid therapy having a significant negative association with the number of laminae (P < 0.02). A negative association between KCO and the number of layers of basement membrane (R = 0.51, P = 0.01) was documented. However, multiple regression analysis revealed no association between parameters of thickened vessel walls and the presence of muscle fibre atrophy.

Abstract
Five elderly patients presenting with neuropsychiatric systemic lupus erythematosus were referred to the sectorised psychiatry service of the department of health care of the elderly. They represented 2% of patients admitted over a period of two years. Two patients presented with a subacute confusional state, two with dementia, and one with depression. Three patients responded well to treatment. This suggests that systemic lupus erythematosus (SLE) is more common in elderly people than was originally thought and is a potentially treatable cause of organic brain disorder. The absence of reports of elderly patients with SLE is likely to be due to the continued application of the American Rheumatism Association's revised 1982 classification criteria, which are inappropriate for this population.

Abstract
A system for assessing symptoms (pain, stiffness, gelling) and signs (local temperature, effusion, tenderness, synovial swelling, popliteal cyst, crepitus) of osteoarthritis of the knee has been developed. The system has been assessed for intra- and interobserver variation using normal and osteoarthritic knees. Intraobserver variability is low for all indices but interobserver variability is high for physical signs. It is suggested that the components within this system, when applied by a single observer, may provide a reasonable framework for clinical assessment of osteoarthritis of the knee.

Abstract
It has been reported that migraine is common in systemic lupus erythematous (SLE) and an association with phospholipid antibodies has been suggested. The incidence of migraine and non-migrainous headache was prospectively studied in 90 patients with SLE and 90 age- and sex-matched controls. A history of migraine was commoner in SLE patients than in controls [31(34%) vs 15(16%); P less than 0.05], and the mean age of onset was higher in the SLE group (26.8 vs 17.2 years). Within the SLE group an association was found between migraine and SLE disease activity. Non-migrainous headaches were also more common (non-significant) in the SLE group, and there was a close temporal relationship between onset of both headache and SLE in many patients. Both migraine and non-migrainous headaches in SLE patients often responded to specific SLE treatment. No association was found between migraine or other headaches and antibodies to phospholipids.

Nailfold capillary density as a possible indicator of pulmonary capillary loss in systemic lupus erythematosus but not in mixed connective tissue disease. J Rheumatol 1991; 18:1532-6.

Abstract
Nailfold capillary density was measured in 24 patients with systemic lupus erythematosus (SLE), 14 with mixed connective tissue disease (MCTD) and 21 healthy subjects. Pulmonary function tests were performed on all subjects and needle muscle biopsies on 12 patients with SLE and 9 with MCTD. A significant correlation was documented between nailfold capillary density and pulmonary gas transfer (KCO) in patients with SLE (p less than 0.001) but not in patients with MCTD. This suggests that in SLE poor gas transfer may be dependent on alveolar capillary loss and that nailfold capillary density may be a good indicator of alveolar capillary density. There was no significant correlation between skeletal muscle fiber atrophy and nailfold capillary density in SLE or MCTD. Additional studies to optimize the nailfold capillary counting method are described.

Abstract
Non-steroidal anti-inflammatory drug induced small intestinal inflammation may have an adverse effect on the joints of patients with rheumatoid arthritis. We therefore assessed small intestinal and joint inflammation in patients with rheumatoid arthritis before and after three to nine months' treatment with sulphasalazine (n = 40) and other second line drugs (n = 20), while keeping the dosage of non-steroidal anti-inflammatory drug at the same level. Sulphasalazine significantly decreased the mean (SD) faecal excretion of 111indium labelled leucocytes from 2.39 (2.22)% to 1.33 (1.13)% (normal less than 1%, p less than 0.01) and improved the joint inflammation as assessed by a variety of parameters. There was no significant correlation between the effects of sulphasalazine treatment on the intestine and the joints. Treatment with other second line drugs had no significant effect on the faecal excretion of 111indium (1.58 (1.04)% and 1.86 (1.51)%, respectively) but improved joint inflammation significantly. The lack of correlation between the intestinal and joint inflammation and their response to treatment suggests that the two are not causally related.
