A preliminary study in classification of the severity of spine deformation in adolescents with lumbar/thoracolumbar idiopathic scoliosis using machine learning algorithms based on lumbosacral joint efforts during gait.

To assess the severity and progression of adolescents with idiopathic scoliosis (AIS), radiography with X-rays is usually used. The methods based on statistical observations have been developed from 3D reconstruction of the trunk or topography. Machine learning has shown great potential to classify the severity of scoliosis on imaging data, generally on X-ray measurements.

Static Postural Control Deficits in Adults with Myotonic Dystrophy Type 1, Steinert Disease.

Background: Myotonic dystrophy type 1 (DM1) is characterized by progressive and predominantly distal muscle atrophy and myotonia. Gait and balance impairments, resulting in falls, are frequently reported in this population. However, the extent to which individuals with DM1 rely more on a specific sensory system for balance than asymptomatic individuals (AI) is unknown.

Anti-inflammatory treatment after cataract surgery in Sweden: changes in prescribing patterns from 2010 to 2017.

Aims: To investigate changes in the prescribing patterns of postoperative eye drops following cataract surgery in Sweden from 2010 to 2017.

Methods: Data from cataract procedures registered in the National Cataract Register during the month of March from 2010 to 2017 were record linked and sent to the Swedish Prescribed Drug Register, which allowed us to determine which eye drops the patients had obtained from 3 months presurgery to 2 weeks post surgery.

Results: During the 8-year study period, 54 889 surgeries were registered.

Identification of the most relevant intervertebral effort indicators during gait of adolescents with idiopathic scoliosis.

The intervertebral efforts, i.e., forces and torques, during gait have been recognized as influencing the progression of scoliosis, due to the mechanical modulations according to the Hueter-Volkmann Law.

Effect of Bi-Level Positive Airway Pressure (BIPAP) Ventilation on Gas Exchange, Body Mass Index, and Body Composition in Patients with Obesity Hypoventilation Syndrome.

Background: This study aimed to assess the outcomes of bi-level positive airway pressure (BIPAP) therapy among patients with obesity hypoventilation syndrome (OHS).

Materials And Methods: In this prospective observational study, a total of 30 patients with OHS, who were subjected to BIPAP therapy, were included. The peripheral capillary oxygen saturation (SPO), partial pressure of carbon dioxide (PCO), body mass index (BMI), and body composition indices, including total body fat (TBF), total body protein (TBP), total body mineral (TBM), and total body water (TBW), were measured using standard procedures at baseline and one week, one month, and six months after the onset of treatment.

Decomposition of three-dimensional ground-reaction forces under both feet during gait.

Unlabelled: Three-dimensional ground reaction forces (3D-GRF) are essential for functional evaluation for rehabilitation. A platform path is required to obtain the 3D-GRF. The main shortcoming of these platform paths is that during double stance phases of gait, both feet can be placed on the same force platform causing the need for decomposing the 3D-GRF under each foot.

Improving patient-assessed outcomes after cataract surgery.

Purpose: To identify and evaluate possible causes of poor patient-reported visual function after cataract surgery.

Methods: We obtained retrospective data from the Swedish National Cataract Register on patient self-assessed visual function before and after cataract surgery based on the Catquest-9SF questionnaire. We identified patients who self-reported similar or more difficulties postoperatively than preoperatively, and looked at possible causative variables such as sex, age, preoperative and postoperative corrected distance visual acuity (CDVA) and refractive errors, and ocular comorbidity.

Custom sizing of lower limb exoskeleton actuators using gait dynamic modelling of children with cerebral palsy.

The use of exoskeletons as an aid for people with musculoskeletal disorder is the subject to an increasing interest in the research community. These devices are expected to meet the specific needs of users, such as children with cerebral palsy (CP) who are considered a significant population in pediatric rehabilitation. Although these exoskeletons should be designed to ease the movement of people with physical shortcoming, their design is generally based on data obtained from healthy adults, which leads to oversized components that are inadequate to the targeted users.

Spinal Cord Infarct During Concomitant Circulatory Support With Intra-Aortic Balloon Pump and Veno-Arterial Extracorporeal Membrane Oxygenation.

Objective: To report a series of three patients who received simultaneous circulatory support with both veno-arterial extracorporeal membrane oxygenation and intra-aortic balloon pump and subsequently developed spinal cord infarction, and present a brief review of the relevant literature.

Data Sources: Hospital medical records and MEDLINE and PubMed databases.

Study Selection: Any patient who developed lower limb neurologic symptoms during a period of concurrent venoarterial extracorporeal membrane oxygenation and intra-aortic balloon pump support, with subsequent MRI changes involving the spinal cord, from 2006 (the year of institution of venoarterial extracorporeal membrane oxygenation in our ICU) to 2014.

Survey of medical residents' attitude toward physical medicine and rehabilitation.

This survey was completed on 600 medical residents in 19 randomly selected teaching hospitals from three Iranian medical universities to delineate some possible factors associated with medical residents' awareness of and attitude toward 11 specified areas of physical medicine and rehabilitation (PM&R). Fifty-four percent of the participants had a history of consultation with physiatrists. Male residents and those with history of general medicine education in a university having a residency program in PM&R were the most likely to consult with physiatrists.

Estimation of region of attraction for polynomial nonlinear systems: a numerical method.

This paper introduces a numerical method to estimate the region of attraction for polynomial nonlinear systems using sum of squares programming. This method computes a local Lyapunov function and an invariant set around a locally asymptotically stable equilibrium point. The invariant set is an estimation of the region of attraction for the equilibrium point.

Splanchnic vein thrombosis in severe acute pancreatitis: a 2-year, single-institution experience.

Objectives: This study aimed to determine current practice in the management and outcome of splanchnic vein thrombosis complicating acute pancreatitis (AP).

Methods: An audit of prospectively collected data for all patients presenting with AP was conducted. Patients with splanchnic vein thrombosis were grouped according to vessel involvement and whether or not systemic anticoagulation was administered.

Neural network control of communications systems.

Neural networks appear well suited to applications in the control of communications systems for two reasons: adaptivity and high speed. This paper describes application of neural networks to two problems, admission control and switch control, which exploit the adaptivity and speed property, respectively. The admission control problem is the selective admission of a set of calls from a number of inhomogeneous call classes, which may have widely differing characteristics as to their rate and variability of traffic, onto a network.
