Understanding changes in echocardiographic parameters at different ages following fetal growth restriction:a systematic review and meta-analysis

Fetal growth restriction (FGR) increases cardiovascular risk by cardiac remodeling and programming. This systematic review and meta-analysis across species examines the use of echocardiography in FGR offspring at different ages. PubMed and Embase.com were searched for animal and human studies reporting on echocardiographic parameters in placental insufficiency- induced FGR offspring. We included six animal and 49 human studies. Although unable to perform a meta-analysis of animal studies because of insufficient number of studies per individual outcome, all studies showed left ventricular dysfunction. Our meta-analyses of human studies revealed a reduced left ventricular mass, interventricular septum thickness, mitral annular peak velocity, and mitral lateral early diastolic velocity at neonatal age. No echocardiographic differences during childhood were observed, although the small age range and number of studies limited these analyses. Only two studies at adult age were performed. Meta-regression on other influential factors was not possible due to underreporting. The few studies on myocardial strain analysis showed small changes in global longitudinal strain in FGR offspring. The quality of the human studies was considered low and the risk of bias in animal studies was mostly unclear. Echocardiography may offer a noninvasive tool to detect early signs of cardiovascular predisposition following FGR. Clinical implementation yet faces multiple challenges including identification of the most optimal timing and the exact relation to long-term cardiovascular function in which echocardiography alone might be limited to reflect a child's vascular status. Future research should focus on myocardial strain analysis and the combination of other (non)imaging techniques for an improved risk estimation.</p

Prevention of Complex Regional Pain Syndrome type 1 after conservative treatment of a distal radius fracture with a home exercise program: A proof-of-concept study.

Purpose: Prevention of CRPS-1, a post-traumatic pain syndrome, after a distal radius fracture is important as this syndrome might lead to chronic pain and serious disabilities. In several studies, it was shown that CRPS-1 can be cured with exercise and graded activities.Method: In a prospective cohort study, a home exercise program with progressive loading exercises was applied immediately after cast removal in patients with a distal radius fracture. After three months, patients were interviewed by telephone using the subjective Budapest diagnostic criteria for CRPS-1.Results: In our study, 56 patients were included and 9 patients (16%) scored positive on the subjective diagnostic criteria. None of the 9 patients was diagnosed with CRPS-1.Conclusion: This study indicates that a home exercise program after conservative treatment of distal radius fracture is a safe and effective option to prevent CRPS-1. A larger study is needed to prove the preventive power of this home exercise program.Level of evidence:

Safety of osseointegrated implants for transfemoral amputees : a two-center prospective cohort study

Background: Osseointegrated implants are an alternative for prosthetic attachment for individuals unable to wear a socket following an amputation. The concept of an integrated metal implant communicating with the external environment raises substantial concern about the risk of ascending infection. We report on the safety of press-fit osseointegrated implants currently used in Australia and the Netherlands. Methods: We prospectively recorded all adverse events in all patients with transfemoral amputation who were managed with an osseointegration implant system between 2009 and 2013 at two centers. The procedure was performed in two stages. A customized porous-coated implant was placed in the first stage, and a stoma was created in the second. Adverse events were categorized according to type (infection or “other”) and severity. Infections were classified according to four grades of severity based on clinical and radiographic findings: (1) low-grade soft-tissue infection, (2) high-grade soft-tissue infection, (3) bone infection, and (4) septic implant failure. Results: Eighty-six patients (ninety-one implants), twenty-five to eighty-one years of age, were included in the study and followed for a median of thirty-four months (range, twenty-four to seventy-one months). Thirty-one patients had an uneventful course with no complications; twenty-nine developed infection (all grade 1 or 2); and twenty-six did not develop infection but had one or more other complications requiring intervention, including stoma hypergranulation (seventeen patients), soft-tissue redundancy (fourteen), proximal femoral fracture (three), inadequate osseointegration leading to implant replacement (one), implant breakage (two), and breakage of the pin used as a fail-safe mechanism (twenty-five). Conclusions: Mild infection and irritation of the soft tissue in the skin-penetration area are common in transfemoral amputees who have an osseointegrated implant. These complications were successfully managed with simple measures. Severe infections resulting in septic implant loosening are rare.10 page(s

Ten Meters Walking Speed in Spinal Cord-Injured Patients: Does Speed Predict Who Walks and Who Rolls?

Background. Walking speed is assumed to be a key factor in regaining ambulation after spinal cord injury (SCI). However, from the literature it remains unclear which walking speed usually results in independent community ambulation. Objective. The primary aim of this study was to determine at which walking speed SCI patients tend to walk in the community instead of using a wheelchair. The secondary aim was to investigate clinical conditions that favor independent ambulation in the community. Methods. Data from SCI patients were collected retrospectively from the European Multicenter Study about Spinal Cord Injury database. We determined a cutoff walking speed at which the patients tend to walk in the community by plotting a receiver operating characteristics curve, using the Spinal Cord Independence Measure for outdoor mobility. Univariate analyses investigated which factors influence independent community ambulation. Results. A walking speed of 0.59 m/s is the cutoff between patients who do and do not ambulate independently in the community, with a sensitivity of 91.6% and a specificity of 80.3%. Age, injury severity, and lower limb muscle strength have a significant influence on independent community ambulation. Conclusions. Patients with an SCI who regain a walking speed of 0.59 m/s tend to achieve a level of walking effectiveness that allows for independent community walking. Although such patients tend to be younger and less severely injured, this walking speed can be a target for locomotor training in rehabilitation and clinical trials that lead to a meaningful outcome level of community walking.</jats:p

A Framework for Measuring the Progress in Exoskeleton Skills in People with Complete Spinal Cord Injury

For safe application of exoskeletons in people with spinal cord injury at home or in the community, it is required to have completed an exoskeleton training in which users learn to perform basic and advanced skills. So far, a framework to test exoskeleton skills is lacking. The aim of this study was to develop and test the hierarchy and reliability of a framework for measuring the progress in the ability to perform basic and advanced skills. Twelve participants with paraplegia were given twenty-four training sessions in 8 weeks with the Rewalk-exoskeleton. During the 2nd, 4th, and 6th training week the Intermediate-skills-test was performed consisting of 27 skills, measured in an hierarchical order of difficulty, until two skills were not achieved. When participants could walk independently, the Final-skills-test, consisting of 20 skills, was performed in the last training session. Each skill was performed at least two times with a maximum of three attempts. As a reliability measure the consistency was used, which was the number of skills performed the same in the first two attempts relative to the total number. Ten participants completed the training program. Their number of achieved intermediate skills was significantly different between the measurements XF2(2) = 12.36, p = 0.001. Post-hoc analysis revealed a significant increase in the median achieved intermediate skills from 4 [1–7] at the first to 10.5 [5–26] at the third Intermediate-skills-test. The rate of participants who achieved the intermediate skills decreased and the coefficient of reproducibility was 0.98. Eight participants met the criteria to perform the Final-skills-test. Their median number of successfully performed final skills was 16.5 [13–20] and 17 [14–19] skills in the first and second time. The overall consistency of &gt;70% was achieved in the Intermediate-skills-test (73%) and the Final-skills-test (81%). Eight out of twelve participants experienced skin damage during the training, in four participants this resulted in missed training sessions. The framework proposed in this study measured the progress in performing basic and advanced exoskeleton skills during a training program. The hierarchical ordered skills-test could discriminate across participants' skill-level and the overall consistency was considered acceptable

Cost-effectiveness of an integrated 'fast track' rehabilitation service for multi-trauma patients: A non-randomized clinical trial in the Netherlands

<div><p>Background</p><p>Multidisciplinary rehabilitation has been recommended for multi-trauma patients, but there is only low-quality evidence to support its use with these patients. This study examined whether a Supported Fast track multi-Trauma Rehabilitation Service (Fast Track) was cost-effective compared to conventional trauma rehabilitation service (Care As Usual) in patients with multi-trauma from a societal perspective with a one-year follow-up.</p><p>Methods</p><p>An economic evaluation alongside a prospective, multi-center, non-randomized, controlled clinical study, was conducted in the Netherlands. The primary outcome measure was the Functional Independence Measure (FIM). Generic Quality of Life and Quality Adjusted Life Years (QALYs) of the patients were derived using the Short-form 36 Health Status Questionnaire.</p><p>Incremental Cost-Effectiveness Ratios (ICERs) were stated in terms of costs per unit of FIM improvement and costs per QALY. To investigate the uncertainty around the ICERs, non-parametric bootstrapping was used.</p><p>Results</p><p>In total, 132 patients participated, 65 Fast Track patients and 67 Care As Usual patients. Mean total costs per person were €18,918 higher in the Fast Track group than in the Care As Usual group. Average incremental effects on the FIM were 3.7 points (in favor of the Fast Track group) and the incremental (extra) bootstrapped costs were €19,033, resulting in an ICER for cost per FIM improvement of €5,177. Care As Usual dominated Fast Track in cost per QALY as it gave both higher QALYs and lower costs. All sensitivity analyses attested to the robustness of our results.</p><p>Conclusions</p><p>This study demonstrated that a multidisciplinary rehabilitation program for multi-trauma patients according to the supported fast track principle is promising but cost-effectiveness evidence remains inconclusive. In terms of functional outcome, Fast Track was more expensive but yielded also more effects compared to the Care As Usual group. Looking at the costs per QALYs, unfavorable ICERs were found. Given the lack of a willingness-to-pay threshold for functional recovery and the relatively short time horizon, it is not possible to draw firm conclusions about the first.</p><p>Trial registration</p><p>(Current Controlled Trials register: <a href="http://www.isrctn.com/ISRCTN68246661" target="_blank">ISRCTN68246661</a>).</p></div

Effects of an Integrated ‘Fast Track’ Rehabilitation Service for Multi-Trauma Patients: A Non-Randomized Clinical Trial in the Netherlands

<div><p>Objectives</p><p>The effects on health related outcomes of a newly-developed rehabilitation program, called ‘supported Fast Track multi-trauma rehabilitation service’ (Fast Track), were evaluated in comparison with conventional trauma rehabilitation service (Care as Usual).</p><p>Methods</p><p>Prospective, multi-center, non-randomized controlled study. Between 2009 and 2012, 132 adult multi-trauma patients were included: 65 Fast Track and 67 Care as Usual patients with an Injury Severity Score ≥16, complex multiple injuries in several extremities or complex pelvic and/or acetabulum fractures. The Fast Track program involved: <i>integrated</i> coordination between trauma surgeon and rehabilitation physician, shorter stay in hospital with faster transfer to a specialized trauma rehabilitation unit, earlier start of multidisciplinary treatment and ‘non-weight bearing’ mobilization. Primary outcomes were functional status (FIM) and quality of life (SF-36) measured through questionnaires at baseline, 3, 6, 9 and 12 months post-trauma. Outcomes were analyzed using a linear mixed-effects regression model.</p><p>Results</p><p>The FIM scores significantly increased between 0 and 3 months (p<0.001) for both groups showing that they had improved overall, and continued to improve between 3 and 6 months for Fast Track (p = 0.04) and between 3 and 9 months for Care as Usual (p = 0.03). SF-36 scores significantly improved in both groups between 3 and 6 months (Fast Track, p<0.001; Care as Usual, p = 0.01). At 12 months, SF-36 scores were still below (self-reported) baseline measurements of patient health prior to the accident. However, the FIM and SF-36 scores differed little between the groups at any of the measured time points.</p><p>Conclusion</p><p>Both Fast Track and Care as Usual rehabilitation programs were effective in that multi-trauma patients improved their functional status and quality of life. A faster (maximum) recovery in functional status was observed for Fast Track at 6 months compared to 9 months for Care as Usual. At twelve months follow-up no differential effects between treatment conditions were found.</p><p>Trial Registration</p><p><a href="http://www.isrctn.com/search?q=68246661" target="_blank">ISRCTN68246661</a></p></div
