Experiences of people with non-traumatic spinal cord injuries returning home after inpatient rehabilitation

PURPOSE

The aim of this study was to explore the experience of people with non-traumatic spinal cord injuries who have recently returned home from inpatient rehabilitation.

METHODS

Semi-structured interviews were conducted with seven adults with non-traumatic spinal cord injuries who had been discharged from inpatient rehabilitation from an Australian rehabilitation hospital, within the last two years.

RESULTS

Three themes were identified: the practicalities of coming home; adjusting to "my altered home life"; pursuing recovery. When people felt prepared by their rehabilitation service, and had appropriate support from others, they had a more positive adjustment experience, although not one without challenges. Due to less independence and inability to participate in meaningful life roles, participants experienced a sense of lost or changed identity. Maintaining hope for physical recovery was very important and motivated participants to actively engage in rehabilitation efforts.

CONCLUSIONS

This study adds to the knowledge regarding the lived experience of people with non-traumatic spinal cord injury transitioning from rehabilitation to home. Facilitators for successful rehabilitation discharge included ensuring community services contacted patients immediately after they left hospital, and providing support for carers. Health care workers can positively influence the adjustment process of people with NTSCI by facilitating re-engagement in meaningful roles.IMPLICATIONS FOR REHABILITATIONThe transition home from inpatient rehabilitation after non-traumatic spinal cord injury (NTSCI) is facilitated by early discharge planning and follow-up from services after discharge.Establishing routines helped participants adjust to their new circumstances.The emotional and practical support of carers is vital for successful adjustment to living in the community with an NTSCI.Health care workers can positively influence the adjustment process of people with NTSCI by facilitating their re-engagement in meaningful roles.

Musculoskeletal Injury in Referees That Officiate Over Ladies Gaelic Football and Camogie

Aim Ladies Gaelic football and Camogie are leading female sports in Ireland. Referees are essential to the game, however, no research has examined injury in referees that officiate over female Gaelic games to date. Therefore, this study aims to retrospectively examine the musculoskeletal injury profile and injury prevention practices of referees that officiate over female Gaelic games. Methods A retrospective anonymous questionnaire examined injuries that occurred in the previous 12 months in currently active Ladies Gaelic football and Camogie referees (n=170). Incidence and repeat incidence proportions were calculated along with descriptive statistics. Results In 2019, 42.9% (n=73) of referees sampled sustained an injury with 27.4% (n=20) sustaining two or more. Injuries primarily occurred to the lower extremity (79.6%,n=78), particularly the lower leg (20.4%,n=20) and knee (18.4%,18). Muscle strains and cramps (55.1%,n=54) were most frequent and injuries predominantly occurred during games (71.4%,n=70). Referees largely completed a warm-up but just 30.6% (n=52) conducted a cool-down. Over half had undertaken injury prevention education but only 37.6% (n=64) incorporated injury prevention elements into their training. Conclusion Just over two in five referees that officiate female Gaelic games became injured in the previous year, however their utilisation of injury prevention strategies, beyond completing a warm-up, is lacking. Thus, a referee specific injury prevention programme should be developed and if found to be effective, incorporated into a comprehensive injury prevention strategy by the governing bodies.

Capacitive monitoring system for real-time respiratory motion monitoring during radiation therapy

Summary

This work introduces a novel capacitive‐sensing technology capable of detecting respiratory motion with high temporal frequency (200 Hz). The system does not require contact with the patient and has the capacity to sense motion through clothing or plastic immobilization devices.

Abstract

Purpose

This work presents and evaluates a novel capacitive monitoring system (CMS) technology for continuous detection of respiratory motion during radiation therapy. This modular system provides real‐time motion monitoring without any contact with the patient, ionizing radiation, or surrogates such as reflective markers on the skin.

Materials and methods

The novel prototype features an array of capacitive detectors that are sensitive to the position of the body and capable of high temporal frequency readout. Performance of this system was investigated in comparison to the RPM infrared (IR) monitoring system (Varian Medical Systems). The prototype included three (5 cm × 10 cm) capacitive copper sensors in one plane, located at a distance of 8–10 cm from the volunteer. Capacitive measurements were acquired for central and lateral‐to‐central locations during chest free‐breathing and abdominal breathing. The RPM IR data were acquired with the reflector block at corresponding positions simultaneously. The system was also tested during deep inspiration and expiration breath‐hold maneuvers.

Results

Capacitive monitoring system data demonstrate close agreement with the RPM status quo at all locations examined. Cross‐correlation analysis on RPM and CMS data showed an average absolute lag of 0.07 s (range: 0.03–0.23 s) for DIBH and DEBH data and 0.15 s (range: 0–0.43 s) for free‐breathing. Amplitude difference between the normalized CMS and RPM signal during chest and abdominal breathing was within 0.15 for 94.3% of the data points after synchronization. CMS performance was not affected when the subject was clothed.

Conclusion

This novel technology permits sensing of both free‐breathing and breath‐hold respiratory motion. It provides data comparable to the RPM system but without the need for an IR tracking camera in the treatment room or use of reflective markers on the patient.

Describing a Process for Creating a Patient Visible Quality Educational Display to Increase Patient Engagement in Radiation Oncology Throughout the Canadian Maritimes Provinces

Here, we report the process for creating a patient visible quality educational display to highlight the collaborative quality working practices of Radiation Oncology clinicians and staff in the main Radiotherapy Centers throughout three Canadian provinces. These processes are often not visible to patients yet they speak directly to the standards of care delivered at these centers. The Canadian Partnership for Quality Radiotherapy (CPQR) Quality Assurance Guidelines for Canadian Radiation Treatment Programs guided this process. The display slides created were approved by the local Radiation Oncology departmental leadership for each participating medical center as well as patient focus groups and revised with feedback from both perspectives. Of 27 patients/families who evaluated the resulting educational patient display, 70% expressed high engagement in the information presented, and 81% felt the display will be of interest to patients receiving radiotherapy treatment. Patients/families surveyed reported that the displayed content made them feel more informed and more comfortable with their treatments. Survey data from this project indicates that increasing transparency and deepening patient education about the quality working practices behind radiotherapy treatments has the potential to empower patients receiving radiotherapy and increase their confidence in the care they are receiving.

Is stiffness related to athletic groin pain?

Athletic groin pain (AGP) is a common injury prevalent in field sports. One biomechanical measure that may be of importance for injury risk is stiffness. To date, [corrected] however, stiffness has not been examined in AGP. The primary aim was to determine whether AGP affects vertical and joint stiffness and if so, whether successful rehabilitation is associated with a change in stiffness. Sixty-five male patients with AGP and fifty male controls were recruited to this study. Assessment included a biomechanical examination of stiffness during a lateral hurdle hop test. Subjects with AGP were tested pre- and post-rehabilitation, while controls were tested once. AGP subjects were cleared for return to play in a median time of 9.14 weeks (5.14-29.0). Stiffness was significantly different at pre-rehabilitation in comparison with controls for three [corrected] of the ten stiffness values examined: ankle plantar flexor, knee extensor, hip abductor, and vertical stiffness (P <  .05, D = 0.38-0.81). [corrected]. Despite clearance for return to play, of these four variables, only hip abductor stiffness changed significantly from pre- to post-rehabilitation (P = .05, D = 0.36) [corrected] to become non-significantly different to the uninjured group (P = .23, D = 0.23). [corrected]. These findings suggest that hip abductor stiffness may represent a target for AGP rehabilitation. Conversely, given the clearance for return to play, the lower sagittal plane and vertical stiffness in the AGP group in comparison with the uninjured controls likely represents either a compensatory mechanism to reduce the risk of further injury or a consequence of neuromuscular detraining.

Clinical interventions to reduce stillbirths in sub-Saharan Africa: a mathematical model to estimate the potential reduction of stillbirths associated with specific obstetric conditions

OBJECTIVE

Stillbirths are among the most common adverse pregnancy outcomes, with 98% occurring in low-income countries. More than one-third occur in sub-Saharan Africa (SSA). However, the medical conditions causing stillbirths and interventions to reduce stillbirths from these conditions are not well documented. We estimated the reductions in stillbirths possible with combinations of interventions.

DESIGN

We developed a computerised model to estimate the impact of various interventions on stillbirths caused by the most common conditions. The model considered the location of obstetric care (home, clinic or hospital) and each intervention's efficacy, penetration and utilisation. Maternal transfers were also considered.

SETTING AND POPULATION

Pregnancies in SSA in 2012.

METHODS

For each condition, we created a series of scenarios involving different combinations of interventions and modelled their impact on stillbirth rates.

MAIN OUTCOME MEASURES

Stillbirths associated with various maternal and fetal conditions and the percentage reduction with various interventions.

RESULTS

Eight to ten maternal and fetal conditions were responsible for most stillbirths, but none for more than 15%. The most common conditions causing stillbirths in SSA include obstructed labour and uterine rupture, fetal distress and umbilical cord complications, fetal growth restriction, pre-eclampsia/eclampsia, and placental abruption/placenta praevia. Syphilis and malaria contribute smaller numbers. Reducing stillbirths requires appropriate diagnosis and management of each condition, usually including hospital care for monitoring and delivery, often by caesarean section. Maternal syphilis and malaria were the only conditions for which outpatient management alone reduced stillbirth.

CONCLUSIONS

Most stillbirths in low-income countries occur at term and during labour and therefore are preventable by appropriate obstetric care. Management focused on the maternal and fetal conditions that cause stillbirths is necessary to achieve stillbirth rates approaching those found in high-income countries.

TWEETABLE ABSTRACT

Reducing stillbirth incidence requires appropriate management of each causative condition and often caesarean delivery.

Intrapatient study comparing 3D printed bolus versus standard vinyl gel sheet bolus for postmastectomy chest wall radiation therapy

PURPOSE

This patient study evaluated the use of 3-dimensional (3D) printed bolus for chest wall radiation therapy compared with standard sheet bolus with regard to accuracy of fit, surface dose measured in vivo, and efficiency of patient setup. By alternating bolus type over the course of therapy, each patient served as her own control.

METHODS AND MATERIALS

For 16 patients undergoing chest wall radiation therapy, a custom 5.0 mm thick bolus was designed based on the treatment planning computed tomography scan and 3D printed using polylactic acid. Cone beam computed tomography scanning was used to image and quantify the accuracy of fit of the 2 bolus types with regard to air gaps between the bolus and skin. As a quality assurance measure for the 3D printed bolus, optically stimulated luminescent dosimetry provided in vivo comparison of surface dose at 7 points on the chest wall. Durations of patient setup and image guidance were recorded and compared.

RESULTS

In 13 of 16 patients, the bolus was printed without user intervention, and the median print time was 12.6 hours. The accuracy of fit of the bolus to the chest wall was improved significantly relative to standard sheet bolus, with the frequency of air gaps 5 mm or greater reduced from 30% to 13% (P < .001) and maximum air gap dimension diminished from 0.5 ± 0.3 to 0.3 ± 0.3 mm on average. Surface dose was within 3% for both standard sheet and 3D printed bolus. On average, the use of 3D printed bolus reduced the setup time from 104 to 76 seconds.

CONCLUSIONS

This study demonstrates 3D printed bolus in postmastectomy radiation therapy improves fit of the bolus and reduces patient setup time marginally compared with standard vinyl gel sheet bolus. The time savings on patient setup must be weighed against the considerable time needed for the 3D printing process.

Effects of high inclusion of soybean meal and a phytase superdose on growth performance of weaned pigs housed under the rigors of commercial conditions

Two studies were conducted to determine whether soybean meal (SBM) use in nursery pig diets can be increased by superdosing with phytase. In Exp. 1, 2,550 pigs (BW of 5.54 ± 0.09 kg) were used to evaluate the optimal level of phytase in low- or high-SBM diets. Two SBM levels (low and high) and 4 phytase doses (0, 1,250, 2,500, and 3,750 phytase units [FTU]/kg) were combined to create 8 dietary treatments in a 2 × 4 factorial arrangement. Pigs were fed a 3-phase feeding program, with each period being 10, 10, and 22 d, respectively. Inclusion of low and high SBM was 15.0 and 25.0%, respectively, for Phase 1; 19.0 and 29.0%, respectively, for Phase 2; and 32.5% for the common Phase 3 diet. Pigs fed diets with high SBM had improved G:F for Phase 1 and 2 and overall ( < 0.01) compared with low-SBM diets. Phytase quadratically improved G:F during Phase 3 and overall ( < 0.05), with the optimum phytase dose being 2,500 FTU/kg. High-SBM diets tended ( = 0.09) to decrease stool firmness (determined daily from d 1 to 10) only on d 2. In Exp. 2, 2,112 pigs (BW of 5.99 ± 0.10 kg) were used to evaluate the impact of high levels of SBM and phytase on performance, stool firmness, mortality, and morbidity in weaned pigs originating from a porcine reproductive and respiratory syndrome (PRRS) virus-positive sow farm. Pigs were fed a 3-phase feeding program as in Exp. 1. Three levels of SBM (low, medium, or high) and 2 phytase levels (600 or 2,600 FTU) were combined to create 6 dietary treatments in a 3 × 2 factorial arrangement. Inclusion of SBM was 15.0, 22.5, and 30.0% for Phase 1 and 20.0, 27.5, and 35.0% for Phase 2 for low, medium, and high SBM, respectively, and 29.0% for the common Phase 3 diet. Inclusion of SBM did not affect growth performance. The percentage of pigs removed for medical treatment linearly declined with increasing SBM levels ( = 0.04). High-SBM diets tended ( < 0.10) to decrease stool firmness during d 4 and 5 and high phytase tended ( < 0.10) to improve stool firmness on d 2 and 4. Analyzed PRRS titers in saliva samples collected on d 20 and 42 confirmed the PRRS status of the pigs; however, viral load was not impacted by dietary treatments ( ≥ 0.11). Results indicate that SBM levels in early nursery diets can be increased without decreasing growth performance and may be favorable in pigs originating from PRRS-positive sow farms by reducing costs of medical treatments. Supplementation of phytase at superdose levels can improve growth performance independently from the level of SBM in the diet.

Clinical applications of 3-dimensional printing in radiation therapy

Three-dimensional (3D) printing is suitable for the fabrication of complex radiotherapy bolus. Although investigated from dosimetric and feasibility standpoints, there are few reports to date of its use for actual patient treatment. This study illustrates the versatile applications of 3D printing in clinical radiation oncology through a selection of patient cases, namely, to create bolus for photon and modulated electron radiotherapy (MERT), as well as applicators for surface high-dose rate (HDR) brachytherapy. Photon boluses were 3D-printed to treat a recurrent squamous cell carcinoma (SCC) of the nasal septum and a basal cell carcinoma (BCC) of the posterior pinna. For a patient with a mycosis fungoides involving the upper face, a 3D-printed MERT bolus was used. To treat an SCC of the nose, a 3D-printed applicator for surface brachytherapy was made. The structures' fit to the anatomy and the radiotherapy treatment plans were assessed. Based on the treatment planning computed tomography (CT), the size of the largest air gap at the interface of the 3D-printed structure was 3 mm for the SCC of the nasal septum, 3 mm for the BCC of the pinna, 2 mm for the mycosis fungoides of the face, and 2 mm for the SCC of the nose. Acceptable treatment plans were obtained for the SCC of the nasal septum (95% isodose to 99.8% of planning target volume [PTV]), the BCC of the pinna (95% isodose to 97.7% of PTV), and the mycosis fungoides of the face (90% isodose to 92.5% of PTV). For the latter, compared with a plan with a uniform thickness bolus, the one featuring the MERT bolus achieved relative sparing of all the organs at risk (OARs) distal to the target volume, while maintaining similar target volume coverage. The surface brachytherapy plan for the SCC of the nose had adequate coverage (95% isodose to 95.6% of clinical target volume [CTV]), but a relatively high dose to the left eye, owing to its proximity to the tumor. 3D printing can be implemented effectively in the clinical setting to create highly conformal bolus for photon and MERT, as well as applicators for surface brachytherapy.
