Purpose: It is unclear if undesired practices such as scientific fraud, publication bias, and honorary authorship are present in neuroradiology. Therefore, the objective was to explore the integrity of clinical neuroradiological research using a survey method. Methods: Corresponding authors who published in one of four top clinical neuroradiology journals were invited to complete a survey about integrity in clinical neuroradiology research. Results: A total of 232 corresponding authors participated in our survey. Confidence in the integrity of published scientific work in clinical neuroradiology (0–10 point scale) was rated as a median score of 8 (range 3–10). In linear regression analysis, respondents from Asia had significantly higher confidence (beta coefficient of 0.569, 95% confidence interval, CI: 0.049–1.088, P = 0.032). Of the respondents 8 (3.4%) reported to have committed scientific fraud in the past 5 years, whereas 66 respondents (28.4%) reported to have witnessed or suspected scientific fraud by anyone from their department in the past 5 years. A total of 192 respondents (82.8%) thought that a study with positive results is more likely to be accepted by a journal than a similar study with negative results and 96 respondents (41.4%) had an honorary author on any of their publications in the past 5 years. Conclusion: Experts in the field have overall high confidence in published clinical neuroradiology research; however, scientific integrity concerns are not negligible, publication bias is a problem and honorary authorship is common. The findings from this survey may help to increase awareness and vigilance among anyone involved in clinical neuroradiological research. [ABSTRACT FROM AUTHOR]

Tissue expansion (TE) is a rather widely accepted technique in plastic surgery, with variable indications; among numerous other indications, it is commonly used in scar management. In our research, we focused on the significance of TE as an important armamentarium and valid solution for the treatment of large and old post-burn scars, with good cosmetic and functional outcomes. Our study is a retrospective analysis conducted at Dr. Soliman Fakeeh Hospital, Jeddah, during the period from 2020 to 2023. This retrospective analysis included 15 tissue expanders, which were inserted in eight patients with large post-burn scars. Each patient underwent two stages of scar repair using variable-size tissue expanders. Post-operative assessment for scar quality and patient satisfaction was conducted using the POSAS score system in addition to standard documentation. Our study sheds light on the satisfactory and accepted cosmetic and functional outcomes for skin tissue expanders for post-burn scars and deformities. [ABSTRACT FROM AUTHOR]

Objective: To investigate the view of clinicians on diagnostic radiology and its future. Methods: Corresponding authors who published in the New England Journal of Medicine and the Lancet between 2010 and 2022 were asked to participate in a survey about diagnostic radiology and its future. Results: The 331 participating clinicians gave a median score of 9 on a 0–10 point scale to the value of medical imaging in improving patient-relevant outcomes. 40.6%, 15.1%, 18.9%, and 9.5% of clinicians indicated to interpret more than half of radiography, ultrasonography, CT, and MRI examinations completely by themselves, without consulting a radiologist or reading the radiology report. Two hundred eighty-nine clinicians (87.3%) expected an increase in medical imaging utilization in the coming 10 years, whereas 9 clinicians (2.7%) expected a decrease. The need for diagnostic radiologists in the coming 10 years was expected to increase by 162 clinicians (48.9%), to remain stable by 85 clinicians (25.7%), and to decrease by 47 clinicians (14.2%). Two hundred clinicians (60.4%) expected that artificial intelligence (AI) will not make diagnostic radiologists redundant in the coming 10 years, whereas 54 clinicians (16.3%) thought the opposite. Conclusion: Clinicians who published in the New England Journal of Medicine or the Lancet attribute high value to medical imaging. They generally need radiologists for cross-sectional imaging interpretation, but for a considerable proportion of radiographs, their service is not required. Most expect medical imaging utilization and the need for diagnostic radiologists to increase in the foreseeable future, and do not expect AI to make radiologists redundant. Clinical relevance statement: The views of clinicians on radiology and its future may be used to determine how radiology should be practiced and be further developed. Key Points: • Clinicians generally regard medical imaging as high-value care and expect to use more medical imaging in the future. • Clinicians mainly need radiologists for cross-sectional imaging interpretation while they interpret a substantial proportion of radiographs completely by themselves. • The majority of clinicians expects that the need for diagnostic radiologists will not decrease (half of them even expect that we need more) and does not believe that AI will replace radiologists.

Background: Stroke is a leading cause of mortality and disability and one of the most common neurological conditions globally. Many studies focused on vitamin D as a stroke risk factor, but only a few focused on its serum level as a predictor of stroke initial clinical severity and recovery with inconsistent results. The purpose of this study was to assess the relationship between serum vitamin D levels and stroke clinical severity at admission and functional independence and disability at discharge in Saudi Arabia. Methodology: A retrospective cohort study of adult ischemic stroke patients who had their vitamin D tested and admitted within 7 days of exhibiting stroke symptoms at King Abdulaziz Medical City (KAMC) Jeddah, Saudi Arabia. Based on vitamin D level, the patients were categorized into normal [25(OH)D serum level = 75 nmol/L], insufficient [25(OH)D serum level is 50-75 nmol/L], and deficient [25(OH)D serum level = 50 nmol/L]. The primary outcome was to assess the vitamin D serum level of ischemic stroke patients' clinical severity at admission and functional independence at discharge. The National Institute of Health Stroke Scale (NIHSS) was used to assess the clinical severity, whereas the modified Rankin scale (mRS) was used to assess functional independence and disability. Results: The study included 294 stroke patients, out of 774, who were selected based on the inclusion and exclusion criteria. The mean age of the participants was 68.2 ± 13.4 years, and 49.3% were male. The patients' distribution among the three groups based on their vitamin D levels is: normal (n = 35, 11.9%), insufficient (n = 66, 22.5%), and deficient (n = 196, 65.6%). After adjusting for potential covariates, regression analysis found a significant inverse relationship of NIHSS based on 25(OH)D serum level (beta coefficient: 0.04, SE: 0.01, p = 0.003). Patients with deficient serum vitamin D level also had significantly higher odds of worse functional independence in mRS score [OR: 2.41, 95%CI: (1.13-5.16), p = 0.023] when compared to participants with normal vitamin D level. Conclusion: Low vitamin D levels were associated with higher severity of stroke at admission and poor functional independence and disability at discharge in patients with acute ischemic stroke. Further randomized clinical and interventional studies are required to confirm our findings. [ABSTRACT FROM AUTHOR]
