Recovery of Volitional Motor Control and Overground Walking in Participants With Chronic Clinically Motor Complete Spinal Cord Injury: Restoration of Rehabilitative Function With Epidural Spinal Stimulation (RESTORES) Trial-A Preliminary Study.

Spinal cord injury (SCI) is damage to any part of the spinal cord resulting in paralysis, bowel and/or bladder incontinence, and loss of sensation and other bodily functions. Current treatments for chronic SCI are focused on managing symptoms and preventing further damage to the spinal cord with limited neuro-restorative interventions. Recent research and independent clinical trials of spinal cord stimulation (SCS) or intensive neuro-rehabilitation including neuro-robotics in participants with SCI have suggested potential malleability of the neuronal networks for neurological recovery. We hypothesize that epidural electrical stimulation (EES) delivered via SCS in conjunction with mental imagery practice and robotic neuro-rehabilitation can synergistically improve volitional motor function below the level of injury in participants with chronic clinically motor-complete SCI. In our pilot clinical RESTORES trial (RESToration Of Rehabilitative function with Epidural spinal Stimulation), we investigate the feasibility of this combined multi-modal approach in restoring volitional motor control and achieving independent overground locomotion in participants with chronic motor complete thoracic SCI. Secondary aims are to assess the safety of this combination therapy including the off-label SCS usage as well as improving functional outcome measures. To our knowledge, this is the first clinical trial that investigates the combined impact of this multi-modal EES and rehabilitation strategy in participants with chronic motor complete SCI. Two participants with chronic motor-complete thoracic SCI were recruited for this pilot trial. Both participants have successfully regained volitional motor control below their level of SCI injury and achieved independent overground walking within a month of post-operative stimulation and rehabilitation. There were no adverse events noted in our trial and there was an improvement in post-operative truncal stability score. Results from this pilot study demonstrates the feasibility of combining EES, mental imagery practice and robotic rehabilitation in improving volitional motor control below level of SCI injury and restoring independent overground walking for participants with chronic motor-complete SCI. Our team believes that this provides very exciting promise in a field currently devoid of disease-modifying therapies.

A cross-sectional study of knowledge and practices in the management of patients with Parkinson's disease amongst public practice-based general practitioners and geriatricians.

BACKGROUND: As most patients are likely to first interface with their community general practitioner (GP) or geriatrician for chronic healthcare conditions, these non-neurologists practitioners are well-placed to diagnose, initiate treatment in symptomatic Parkinson's disease (PD) patients, and provide regular and timely management of their PD. However, current studies suggest that the role of the GP and geriatrician in providing holistic care for PD patients may be limited by factors such as patient perceptions, and a lack of knowledge base in the quality measures of care. This paper aims to better understand the different management styles between GPs and geriatricians practicing in public institutions in Singapore, qualify the difficulties they face in providing patient-centric care for PD patients, and identify any gaps in quality measures of care. METHODS: A questionnaire was completed anonymously by GPs (n = 43) and geriatricians (n = 33) based at public institutions, on a voluntary basis before a compulsory didactic teaching on PD. Questions were modelled after quality measures set out by the American Academy of Neurology, specifically eliciting information on falls, non-motor symptoms, exercise regime and medication-related symptoms. "PD management practices and styles" questions were answered by the respondents on a 4-point Likert scale. RESULTS: Geriatricians spent more time in consult with PD patients compared with GPs (median [Q1-Q3] = 20 [15-30] vs 10 [10-15] minutes, p <  0.001). Geriatricians were more comfortable initiating PD medications than GPs (OR = 11.8 [95% CI: 3.54-39.3], p <  0.001), independent of gender, years of practice and duration of consult. Comfort in initiating dopamine replacement therapy (OR 1.06 [1.00-1.36], p = 0.07; aOR = 1.14 [1.02-1.26], p = 0.02) also increased with physician's years of practice. Unfamiliarity with the types and/or doses of the medications was the most cited barrier faced by GPs (76.7%). Geriatricians were more likely than GPs to ask about falls (100% vs 86.0%, p = 0.025), non-motor symptoms (75.8% vs 53.5%, p = 0.049) and the patient's regular physical activities (72.7% vs 41.9%, p = 0.01). CONCLUSIONS: This study identified key patterns in the management practices and styles of non-neurologists physicians, and identified gaps in current practice. Our data suggests that interventions directed at education on PD medication prescriptions and provision of patient PD education, creation of best clinical practice guidelines, and accreditation by national bodies may instil greater confidence in practitioners to initiate and continue patient-centric PD care. A longer consultation duration with PD patients should be considered to allow physicians to get a greater scope of the patient's needs and better manage them.

Medications That Increase Osmolality and Compromise the Safety of Enteral Feeding in Preterm Infants.

BACKGROUND: Medications added to preterm milk feeds have the potential to raise osmolality, causing feed intolerance and necrotizing enterocolitis. OBJECTIVE: The aim of this study was to evaluate changes in the osmolality of milk feeds and water with 14 medications and the diluent amounts required to keep the osmolality below the safety threshold of ≤450 mOsm/kg. Changes in the osmolality of milk with medications while on continuous infusion over 2 and 4 h were determined. METHODS: This study was designed to measure the osmolality of 14 commonly used medications in preterm infants both neat and when supplemented with expressed breast milk (EBM), EBM with fortifier (EBMF), preterm formula (PTF), and water. Dose-effect curves were plotted, and the volume of each diluent was calculated to keep the osmolality ≤450 mOsm/kg. Time-effect curves were plotted at 2 and 4 h for each medication for both EBM and EBMF. RESULTS: Neat osmolality of all except 5 medications were above 2,000 mOsm/kg. The osmolality rose with decreasing proportions of diluents used, depicting an indirect curvilinear relationship between the increasing dilution and osmolality for all except 2 medications. As a diluent, EBM was required in lower dilutions than EBMF. Dilutions needed for additives with PTF were very similar to those of EBM. The change in osmolality over time with additives was statistically significant for EBMF. CONCLUSIONS: EBM and PTF were found to be safer diluents than EBMF for enteral additives. The practice of keeping milk feeds with medications for continuous feeding is safe for a period of 4 h in EBM.
