ABSTRACT

PURPOSE: This study aims to describe the experiences and needs of Canadian speech-language pathologists (SLPs) who conducted communication assessments via telepractice across the lifespan during the first year (2020) of the COVID-19 pandemic.

METHOD: The present study consisted of an online survey that aimed to capture both quantitative aspects of telepractice-based communication assessment and the qualitative experience of shifting to telepractice. One hundred sixty-eight practicing SLPs across Canada participated in the survey, between September 2020 and January 2021. Quantitative results were analysed using descriptive statistics while open-ended responses were analysed using thematic analysis.

RESULT: SLPs identified challenges and opportunities relating to client and family engagement, access to and knowledge of technology, and the reliability of assessment tools. SLPs also identified a future need for online assessment materials and training, such as materials adapted for different communication needs (e.g. augmentative and alternative communication).

CONCLUSION: The present study contributes to a growing understanding worldwide of potential benefits and challenges related to telepractice, fuelled by the necessary shift in practices in our field during the COVID-19 pandemic. The results provide direction for continuing to build a valid and inclusive approach to telepractice in the future.

ABSTRACT

In this work, we set up a new discrete predator-prey competitive model with time-varying delays and feedback controls. By virtue of the difference inequality knowledge, a sufficient condition which guarantees the permanence of the established discrete predator-prey competitive model with time-varying delays and feedback controls is derived. Under some appropriate parameter conditions, we have proved that the periodic solution of the system without delay exists and globally attractive. To verify the correctness of the derived theoretical fruits, we give two examples and execute computer simulations. Our obtained results are novel and complement previous known results.

ABSTRACT

PURPOSE: To evaluate the efficacy of interventional radiological (IR) procedures in iatrogenic urinary tract injury and investigate the factors affecting the outcome.

METHODS: Fifty-eight patients (21 male) with a mean age of 50.3 ± 15.8 years referred for iatrogenic urinary tract injury were enrolled in this study. Technical success was defined as (i) successful placement of a nephrostomy catheter within the renal pelvis and/or (ii) successful antegrade ureteral stent placement (double J stent) between the renal pelvis and bladder lumen. Complete resolution was defined as maintained ureteral patency without an external drain and ureteral stent. The factors that may affect complete resolution [ureteral avulsion, ureterovaginal fistula (UVF), history of malignancy/radiotherapy, and time to IR management] were also investigated. The receiver operating characteristic analysis was performed to estimate the cut-off time point for the IR management timing affecting complete resolution.

RESULTS: The technical success rate for nephrostomy and ureteral stent placement was 100% (n = 58/58) and 78% (n = 28/36), respectively. In 14 patients, non-dilated pelvicalyceal systems were evident. In 18 patients, no further intervention after percutaneous nephrostomy was performed due to (i) poor performance status (n = 6) and (ii) reconstruction surgery upon clinicians’ and/or patients’ request (n = 12). Reconstruction surgery was required in 11 of the remaining 40 patients due to failure of percutaneous treatment (n = 11/40, 27.5%). In six of the patients, ureteral stents could not be removed due to the development of benign ureteral strictures (n = 6/40, 15%). Our complete resolution rate was 57.5% (n = 23/40). Age, gender, type of surgery (endoscopic or open), side and location of the injury did not statistically affect the complete resolution rate. The presence of ureteral avulsion, history of malignancy and radiotherapy individually or in combination significantly affected the complete resolution rate negatively. The presence of UVF also had a negative effect on the complete resolution rate; however, it did not reach statistical significance. Delayed intervention was also a significant factor related to lower complete resolution. The optimal cut-off point of the time interval for favorable clinical outcome was found to be 0-19^th day following the surgery.

CONCLUSION: IR procedures are safe and effective in the management of iatrogenic urinary tract injuries. Antegrade ureteral stenting should be performed as soon as possible to establish ureteral integrity without the development of stricture.

ABSTRACT

BACKGROUND: Although it causes low-dose radiation exposure, dimercaptosuccinic acid (DMSA) renal cortical scintigraphy is the gold standard examination method in the noninvasive diagnosis of renal scar tissue (RST). Shear wave elastography (SWE) has recently come to the fore as a technique for measuring kidney stiffness in the examination of RST. The present study aims to compare DMSA and SWE tests to evaluate whether SWE can be used instead of DMSA as a test that does not cause radiation exposure in pediatric patients.

METHODS: In this prospective study, sonographic elastography was performed on pediatric patients with DMSA images. In the SWE examination, measurements were made from each kidney’s upper, middle and lower parts. DMSA and elastography data were compared for the diagnosis of RST.

RESULTS: A total of 64 patients were included in the present study. There were 68.8% female (n = 44) and 31.2% (n = 20) male patients. There were 45 pediatric patients [Female 30 (66.7%), male 15 (33.3%)] in group 1 (pathological group) and 19 pediatric patients [Female 14 (73.7%), male 5 (26.3%)] in the control group. When DMSA data and SWE values were compared, it was found that elastography did not show a statistically significant performance in predicting renal scarring.

CONCLUSION: In the existing literature, various studies reported different values for the diagnosis of renal stiffness using SWE. Similar to some previous studies, the present study observed no significant correlations between DMSA and SWE. Thus, DMSA preserves its major role and effectiveness as an important predictor of RST in pediatric patients.

ABSTRACT

INTRODUCTION: A DnCNN for image denoising trained with natural images is available in MATLAB. For Tc-99m DMSA images, any loss of clinical details during the denoising process will have serious consequences since denoised image is to be used for diagnosis. The objective of the study was to find whether this pre-trained DnCNN can be used for denoising Tc-99m DMSA images and compare its performance with block matching 3D (BM3D) filter.

MATERIALS AND METHODS: Two hundred forty-two Tc-99m DMSA images were denoised using BM3D filter (at sigma = 5, 10, 15, 20, and 25) and DnCNN. The original and denoised images were reviewed by two nuclear medicine physicians and also assessed objectively using the image quality metrics: SSIM, FSIM, MultiSSIM, PIQE, Blur, GCF, and Brightness. Wilcoxon signed-rank test was applied to find the statistically significant difference between the value of image quality metrics of the denoised images and the corresponding original images.

RESULTS: Nuclear medicine physicians observed no loss of clinical information in DnCNN denoised image and superior image quality compared to its original and BM3D denoised images. Edges/boundaries of the scar were found to be well preserved, and doubtful scar became obvious in the denoised image. Objective assessment also showed that the quality of DnCNN denoised images was significantly better than that of original images at P-value <0.0001.

CONCLUSION: The pre-trained DnCNN available with MATLAB Deep Learning Toolbox can be used for denoising Tc-99m DMSA images, and the performance of DnCNN was found to be superior in comparison with BM3D filter.

ABSTRACT

AIM: To explore the perspectives of adults born prematurely on guidelines for management at extreme premature birth, and personalisation at the limit of viability.

METHODS: We conducted four two-hour online focus group interviews in the Netherlands.

RESULTS: Twenty-three participants born prematurely were included in this study, ranging in age from nineteen to fifty-six years, and representing a variety of health outcomes. Participants shared their perspectives on different types of guidelines for managing extremely premature birth. They agreed that a guideline was necessary to prevent arbitrary treatment decisions and to avoid physician bias. All participants favoured a guideline that is based upon multiple prognostic factors beyond gestational age. They emphasized the importance of discretion, regardless of the type of guideline used. Discussions centred mainly on the heterogeneity of value judgments about outcomes after extreme premature birth. Further, participants defined personalisation as ‘not just looking at numbers and statistics’. They associated personalisation mainly with information provision and decision-making. Participants stressed the importance of involving families in decision-making and taking their care needs seriously.

CONCLUSION: Adults born prematurely prefer a periviability guideline that considers multiple prognostic factors and allows for discretion.

ABSTRACT

Spatiotemporal metrics such as step frequency have been associated with running injuries in some studies. Wearables can measure these metrics and provide real-time feedback in-field, but are often not validated. This study assessed the validity of commercially available wireless instrumented insoles (ARION) for quantifying spatiotemporal metrics during level running at different speeds (2.78-5.0 m s^-1 ,) and slopes (3° and 6° up/downhill) to an instrumented treadmill. Mean raw, percentage and absolute percentage error, and limits of agreement (LoA) were calculated. Agreement was statistically quantified using four thresholds: excellent, <5%; good, <10%; acceptable, <15%; and poor, >15% error. Excellent agreement (<5% error) was achieved for stride time across all conditions, and for step frequency across all but one condition with good agreement. Contact time and swing time generally showed at least good agreement. The mean difference across all conditions was -0.95% for contact time, 0.11% for stride time, 0.6% for swing time, -0.11% for step frequency, and -0.09% when averaged across all outcomes and conditions. The accuracy at an individual level was generally good to excellent, being <10% for all but two conditions, with these conditions being <15%. Additional experiments among four runners showed that step length could also be measured with an accuracy of 1.76% across different speeds with an updated version of the insoles. These findings suggests that the ARION wearable may not only be useful for large-scale in-field studies investigating group differences, but also to quantify spatiotemporal metrics with generally good to excellent accuracy for individual runners.

ABSTRACT

AIMS: To identify the barriers and enablers perceived by hospital-based clinicians to providing evidence-based continence care to inpatients.

DESIGN: This was a cross-sectional study of inpatient clinicians using a questionnaire.

METHODS: Acute care and rehabilitation clinicians from 15 wards that admit patients after stroke at 12 hospitals (NSW = 11, Queensland =1, metropolitan = 4, regional = 8) were invited to complete an online questionnaire. The 58 questions (answered on a 5-point Likert scale) were aligned to 13 of the 14 domains of the Theoretical Domains Framework. Results were dichotomized into ‘strongly agree/agree’ and ‘unsure/disagree/strongly disagree’ and proportions were calculated. Data collection occurred between January 2019 and March 2019.

RESULTS: The questionnaire was completed by 291 participants with 88% being nurses. Barriers were found in nine domains including knowledge; skills; memory attention and decision making; emotion; environmental context and resources; behavioural regulation; social professional role; intensions, social influences; and beliefs about capabilities. Enablers were found in seven domains including goals; social influences; knowledge; skills; social, professional role and identity; reinforcement and beliefs about consequences.

CONCLUSION: This multi-site, multi-professional study that included predominantly nurses highlights the barriers and enablers to inpatient continence care. Future implementation studies in inpatient continence management should address these identified barriers and enablers to improve effectiveness of implementation of evidence-based care.

IMPLICATIONS FOR THE PROFESSION: This study highlights that although there are many barriers to ward nurses providing evidence-based continence care, there are also several enablers. Both should be addressed to improve practice.

REPORTING METHOD: We adhered to the Checklist for Reporting Results of Internet E-Surveys (CHERRIES) (Supplementary File 1).

RELEVANCE TO CLINICAL PRACTICE: Establishing barriers to practice gives a broader understanding of why practice does not occur and establishes areas where researchers and clinicians need to address in order to change behaviour.

ABSTRACT

OBJECTIVE: To examine the differences in both maternal and neonatal outcomes between flexible and non-flexible sacrum positions at birth.

METHODS: A descriptive, cross-sectional, retrospective study was carried out on a sample of low-risk pregnant women. Univariate and multivariate logistic regressions and multivariate linear regressions were conducted to estimate the association between our discrete or continuous variables of interest. Maternal outcomes were perineal tear, maternal blood loss, second stage length; neonatal outcomes were Apgar scores and neonatal asphyxia. Results were adjusted for maternal age, neonatal birth weight, and epidural analgesia.

RESULTS: We considered for final analysis 2198 women. In primiparous women, women giving birth in the all-fours position were significantly more likely to have an intact perineum (P = 0.011) and a shorter length of the second stage of labor (P = 0.022). Maternal age (P = 0.005) and neonatal weight (P = 0.013) significantly increased perineal tearing; maternal age (P = 0.004) and neonatal birth weight (P < 0.001) were significantly associated with a higher amount of blood loss. Maternal age (P = 0.002) and neonatal weight (P < 0.001) significantly increased the length of the second stage of labor. For multiparous women, the side-lying position was significantly correlated with an intact perineum (P = 0.031); maternal age and intact perineum were statistically inversely associated. Epidural analgesia significantly increased the length of the second stage of labor in both nulliparous (P < 0.001) and pluriparous women (P < 0.001). No significant differences were found in neonatal outcomes.

CONCLUSION: Women with a low-risk labor should be free to choose their birth position as flexible sacrum positions are shown to increase maternal well-being and do not affect neonatal health.

ABSTRACT

Our study aimed to evaluate the hip joints of healthy children aged 2-13 years morphometrically through radiographic images. Demographic characteristics of 300 healthy children in our study include an average age of 6.4 years old based on the 2-to-13-year-old bracket and sex classified to 133 girls and 167 boys. A total of 600 normal hips from these children were digitally measured based on Acetabular Index, ACM angle, MZ distance, Sharp angle, CE angle, Femoral Head Coverage Ratio, Cranial, and medial joint space (MJS). *p < 0.05; **p < 0.01 indicated a statistically significant difference. It was found that Acetabular Index, ACM angle, MZ distance, Sharp angle, Cranial, and MJSs decreased with age; Acetabular Depth value and CE angle increased with age; the CE angle differed between the sides (right-left) in the young teens period and in boys; and the cranial joint space (CJS) differed between the sides in girls. In addition, girls had higher values than boys in terms of Acetabular Index, ACM angle, Sharp angle, MZ distance, and Femoral Head Coverage Ratio; CE angle and MJS were higher in girls; and Acetabular Depth Value and CJS did not differ significantly between sexes. Obtaining the normal values will guide in the diagnosis and treatment of many clinical conditions including DDH and Legg-Calve-Perthes disease. It can also be used to compare the hips between healthy children and those diagnosed with Cerebral Palsy.
