ABSTRACT

Adequate and transparent reporting is necessary for critically appraising published research. Yet, ample evidence suggests that the design, conduct, analysis, interpretation, and reporting of oral health research could be greatly improved. Accordingly, the Task Force on Design and Analysis in Oral Health Research-statisticians and trialists from academia and industry-identified the minimum information needed to report and evaluate observational studies and clinical trials in oral health: the OHStat Guidelines. Drafts were circulated to the editors of 85 oral health journals and to Task Force members and sponsors and discussed at a December 2020 workshop attended by 49 researchers. The guidelines were subsequently revised by the Task Force's writing group. The guidelines draw heavily from the Consolidated Standards for Reporting Trials (CONSORT), Strengthening the Reporting of Observational Studies in Epidemiology (STROBE), and CONSORT harms guidelines and incorporate the SAMPL guidelines for reporting statistics, the CLIP principles for documenting images, and the GRADE indicating the quality of evidence. The guidelines also recommend reporting estimates in clinically meaningful units using confidence intervals, rather than relying on P values. In addition, OHStat introduces 7 new guidelines that concern the text itself, such as checking the congruence between abstract and text, structuring the discussion, and listing conclusions to make them more specific. OHStat does not replace other reporting guidelines; it incorporates those most relevant to dental research into a single document. Manuscripts using the OHStat guidelines will provide more information specific to oral health research.

ABSTRACT

Adequate and transparent reporting is necessary for critically appraising research. Yet, evidence suggests that the design, conduct, analysis, interpretation, and reporting of oral health research could be greatly improved. Accordingly, the Task Force on Design and Analysis in Oral Health Research-statisticians and trialists from academia and industry-empaneled a group of authors to develop methodological and statistical reporting guidelines identifying the minimum information needed to document and evaluate observational studies and clinical trials in oral health: the OHstat Guidelines. Drafts were circulated to the editors of 85 oral health journals and to Task Force members and sponsors and discussed at a December 2020 workshop attended by 49 researchers. The final version was subsequently approved by the Task Force in September 2021, submitted for journal review in 2022, and revised in 2023. The checklist consists of 48 guidelines: 5 for introductory information, 17 for methods, 13 for statistical analysis, 6 for results, and 7 for interpretation; 7 are specific to clinical trials. Each of these guidelines identifies relevant information, explains its importance, and often describes best practices. The checklist was published in multiple journals. The article was published simultaneously in JDR Clinical and Translational Research, the Journal of the American Dental Association, and the Journal of Oral and Maxillofacial Surgery. Completed checklists should accompany manuscripts submitted for publication to these and other oral health journals to help authors, journal editors, and reviewers verify that the manuscript provides the information necessary to adequately document and evaluate the research.

ABSTRACT

Purpose To compare parameters of left ventricular (LV) and right ventricular (RV) volume and function between a commercially available 0.55-T low-field-strength cardiac cine MRI scanner and a 1.5-T scanner. Materials and Methods In this prospective study, healthy volunteers (May 2022 to July 2022) underwent same-day cine imaging using both scanners (0.55 T, 1.5 T). Volumetric and functional parameters were assessed by two experts. After analyzing the results of a blinded crossover reader study of the healthy volunteers, 20 participants with clinically indicated cardiac MRI were prospectively included (November 2022 to February 2023). In a second blinded expert reading, parameters from clinical 1.5-T scans in these participants were compared with those same-day 0.55-T scans. Results are displayed as Bland-Altman plots. Results Eleven healthy volunteers (mean age: 33 years [95% CI: 27, 40]; four of 11 [36%] female, seven of 11 [64%] male) were included. Very strong mean correlation was observed (r = 0.98 [95% CI: 0.97, 0.98]). Average deviation between MRI systems was 1.6% (95% CI: 0.3, 2.9) for both readers. Twenty participants with clinically indicated cardiac MRI were included (mean age: 55 years [95% CI: 48, 62], six of 20 [30%] female, 14 of 20 [70%] male). Mean correlation was very strong (r = 0.98 [95% CI: 0.97, 0.98]). LV and RV parameters demonstrated an average deviation of 1.1% (95% CI: 0.1, 2.1) between MRI systems. Conclusion Cardiac cine MRI at 0.55 T yielded comparable results for quantitative biventricular volumetric and functional parameters compared with routine imaging at 1.5 T, if acquisition time is doubled.

ABSTRACT

As the world recovers from the COVID-19 pandemic, a resurgence in MPXV cases is causing serious concern. The early clinical similarity of MPXV to common ailments like the flu and cold, coupled with the resemblances of its progressing rash to other infections, underscores the importance of prompt and accurate diagnosis. Among the infections, smallpox is clinically closest to MPXV, and rashes similar to MPXV stages also appear in syphilis and varicella zoster. A comprehensive review of MPXV, herpes, and syphilis was carried out, including structural and morphological features, origins, transmission modes, and computational studies. PubMed literature search on MPXV, using MeSH key terms, yielded 1904 results, with the analysis revealing prominent links to sexually transmitted diseases. More in-depth exploration of MPXV, Herpes Simplex Virus (HSV), and Syphilis revealed further disease interconnections and geographical correlations. These findings emphasize the need for a holistic understanding of these interconnected infectious agents for better control and management.

ABSTRACT

BACKGROUND: In medical education, the learning environment (LE) significantly impacts students' professionalism and academic performance. Positive LE perceptions are linked to better academic outcomes. Our study, which was conducted 15 years after curriculum reform at King Saud University's College of Medicine, aimed to explore students' perspectives on their LE and identify areas for improvement. By understanding their experiences, we strive to enhance LE and promote academic success. METHODS: This mixed-method study employed an explanatory sequential approach in which a cross-sectional analytical survey phase was collected first using the Johns Hopkins Learning Environment Scale (JHLES), followed by qualitative focus groups. Findings from quantitative and qualitative methods were integrated using joint display. RESULTS: A total of 653 medical students completed the JHLES. The total average score was 81 out of 140 (16.8), and the average subscale scores ranged from 2.27 (0.95) for inclusion and safety to 3.37 (0.91) for community of peers. The qualitative approach encompasses both inductive and deductive analyses, identifying overarching themes comprising proudness, high expectations and competition, and views about the curriculum. The integration of results emphasizes the need for continued efforts to create a supportive and inclusive LE that positively influences students' experiences and academic success. CONCLUSION: This research offers valuable insights for educational institutions seeking to enhance medical education quality and support systems. Recommendations include faculty development, the cultivation of supportive environments, curriculum revision, improved mentorship programs, and initiatives to promote inclusivity and gender equity. Future research should explore longitudinal and comparative studies, innovative mixed methods approaches, and interventions to further optimize medical education experiences. Overall, this study contributes to the ongoing dialog on medical education, offering a nuanced understanding of the complex factors influencing students' perceptions and suggesting actionable strategies for improvement.

ABSTRACT

Aims: A comparison of diagnostic performance comparing AI-QCTISCHEMIA, coronary computed tomography angiography using fractional flow reserve (CT-FFR), and physician visual interpretation on the prediction of invasive adenosine FFR have not been evaluated. Furthermore, the coronary plaque characteristics impacting these tests have not been assessed. Methods and results: In a single centre, 43-month retrospective review of 442 patients referred for coronary computed tomography angiography and CT-FFR, 44 patients with CT-FFR had 54 vessels assessed using intracoronary adenosine FFR within 60 days. A comparison of the diagnostic performance among these three techniques for the prediction of FFR ≤ 0.80 was reported. The mean age of the study population was 65 years, 76.9% were male, and the median coronary artery calcium was 654. When analysing the per-vessel ischaemia prediction, AI-QCTISCHEMIA had greater specificity, positive predictive value (PPV), diagnostic accuracy, and area under the curve (AUC) vs. CT-FFR and physician visual interpretation CAD-RADS. The AUC for AI-QCTISCHEMIA was 0.91 vs. 0.76 for CT-FFR and 0.62 for CAD-RADS ≥ 3. Plaque characteristics that were different in false positive vs. true positive cases for AI-QCTISCHEMIA were max stenosis diameter % (54% vs. 67%, P < 0.01); for CT-FFR were maximum stenosis diameter % (40% vs. 65%, P < 0.001), total non-calcified plaque (9% vs. 13%, P < 0.01); and for physician visual interpretation CAD-RADS ≥ 3 were total non-calcified plaque (8% vs. 12%, P < 0.01), lumen volume (681 vs. 510 mm3, P = 0.02), maximum stenosis diameter % (40% vs. 62%, P < 0.001), total plaque (19% vs. 33%, P = 0.002), and total calcified plaque (11% vs. 22%, P = 0.003). Conclusion: Regarding per-vessel prediction of FFR ≤ 0.8, AI-QCTISCHEMIA revealed greater specificity, PPV, accuracy, and AUC vs. CT-FFR and physician visual interpretation CAD-RADS ≥ 3.

ABSTRACT

BACKGROUND: Few literature reviews have been published focusing on navigation, robotic or pre-operative planning using 3D-imaging technology (3D-printing, 3D-planning). To our knowledge, no reviews have been performed to assess and compare all these modalities together versus control groups (conventional fluoroscopy) through high Randomized Control Trials (RCTs) and Prospective Control Studies (PCSs). The aim of this study was to assess and compare 3D-imaging technologies from pre-operative planning to per-operative navigation and robotic in the management of pelvic ring fractures through high level studies. METHODS: A literature search was performed using PubMed, the Cochrane library and Google scholar using keywords up to December 2023. Only prospective comparative studies (RCT and PCS) were included. A total of 341 articles were identified, 39 articles were selected for full-text analysis leaving 7 articles included in this literature systematic review. RESULTS: A trend towards improved precision in screw placement and reduction of radiation exposure without consequences in term of functional outcomes have been identified. No conclusions can be extrapolated regarding operative time and blood loss except for robotic which improve these parameters because robotic arm assistance help surgeons to correctly follow the planning based on 2D-fluoroscopy. Surgery duration and radiation dose are significantly reduced with robotic-arm assistance for the same reasons. With navigation the results have to be nuanced according to the experience of the surgical team. Interest of navigation is emphasized in sacral dysmorphism in comparison with conventional fluoroscopy. This highlights the benefits of navigation for ilio-sacral screw placement in difficult cases and less experimented teams. CONCLUSION: High level studies which assess and compare 3D-imaging technologies from pre-operative planning to per-operative navigation and robotic in the management of pelvic ring fractures are low. To date and according to the present high level literature, navigation and 3D-technologies in pelvic ring surgery should be recommended for difficult cases.

ABSTRACT

In this review article four clinical comparative studies in axial spondylarthritis (axSpA) are presented and discussed. SURPASS as the only head-to-head study investigated the effect of adalimumab biosimilar disease-modifying antirheumatic drug (bsDMARD) or secukinumab on radiographic progression over a time period of 2 years. Overall, the radiographic progression of the spine was low and no significant difference between adalimumab bsDMARD or secukinumab was noted. The three other studies were not constructed as direct head-to-head studies but compared the efficacy of non-steroidal antirheumatic drugs (NSARD) with and without simultaneous treatment with biological DMARDs (bDMARD). The CONSUL study showed no statistically significant difference in the delay of radiographic progression of the spine over 2 years in radiographic axSpA (r-axSpA) patients, who underwent either combined treatment with golimumab and celecoxib or treatment with golimumab alone over 2 years. The ESTHER study showed that patients with early axSpA active inflammatory lesions, which were detected by whole-body magnetic resonance imaging (MRI), showed a significantly greater improvement under treatment with etanercept than those treated with sulfasalazine. The INFAST study showed that patients with early active axSpA who received a combined treatment of infliximab and naproxen, achieved a clinical remission twice as frequently as those who only received naproxen. Therefore, for the endpoint of radiological progression no difference could be shown in the inhibition of radiological progression between the mechanisms of action investigated. The comparative data for the endpoint of clinical efficacy showed that patients with bDMARDs showed a clearly better response to treatment than patients with NSAR or conventional synthetic DMARDs (csDMARD).

ABSTRACT

Purpose To develop and validate a machine learning multimodality model based on preoperative MRI, surgical whole-slide imaging (WSI), and clinical variables for predicting prostate cancer (PCa) biochemical recurrence (BCR) following radical prostatectomy (RP). Materials and Methods In this retrospective study (September 2015 to April 2021), 363 male patients with PCa who underwent RP were divided into training (n = 254; median age, 69 years [IQR, 64-74 years]) and testing (n = 109; median age, 70 years [IQR, 65-75 years]) sets at a ratio of 7:3. The primary end point was biochemical recurrence-free survival. The least absolute shrinkage and selection operator Cox algorithm was applied to select independent clinical variables and construct the clinical signature. The radiomics signature and pathomics signature were constructed using preoperative MRI and surgical WSI data, respectively. A multimodality model was constructed by combining the radiomics signature, pathomics signature, and clinical signature. Using Harrell concordance index (C index), the predictive performance of the multimodality model for BCR was assessed and compared with all single-modality models, including the radiomics signature, pathomics signature, and clinical signature. Results Both radiomics and pathomics signatures achieved good performance for BCR prediction (C index: 0.742 and 0.730, respectively) on the testing cohort. The multimodality model exhibited the best predictive performance, with a C index of 0.860 on the testing set, which was significantly higher than all single-modality models (all P ≤ .01). Conclusion The multimodality model effectively predicted BCR following RP in patients with PCa and may therefore provide an emerging and accurate tool to assist postoperative individualized treatment.

ABSTRACT

Providing quality services, using modern technologies, having effective marketing, and providing services at an international level have led to the globalization of hospital services. This study aimed to identify the components of health services in developing countries that provide services to international patients. A comparative review was conducted by searching in PubMed, Scopus, Web of Science, Google Scholar, Google, and the websites of the World Medical Tourism Organization, the World Bank, and the Ministry of Health of the selected countries from 2000 to 2022. Iran, Turkey, Jordan, Costa Rica, the UAE, and Singapore were selected. The data were collected and analyzed using a comparative table. Different strategies were used to develop the medical tourism industry among the studied countries, but the main challenges in this field included the inappropriateness of the quality of the services provided or the provision of services that did not meet the needs of patients, the lack of expert human resource, not using medical facilitation companies, communication problems with patients, insufficient government support for medical tourism, and strict laws regarding business. The development of activities in the medical tourism industry requires planning in various dimensions. It seems that developing the medical marketing and activities of facilitator companies to facilitate patient admission, monitoring the quality of services provided, improving interdepartmental coordination, and considering a single trustee for this industry will improve the medical tourism status in Iran.

ABSTRACT

Purpose To assess the feasibility of monitoring the effects of elexacaftor-tezacaftor-ivacaftor (ETI) therapy on lung ventilation and perfusion in people with cystic fibrosis (CF), using phase-resolved functional lung (PREFUL) MRI. Materials and Methods This secondary analysis of a multicenter prospective study was carried out between August 2020 and March 2021 and included participants 12 years or older with CF who underwent PREFUL MRI, spirometry, sweat chloride test, and lung clearance index assessment before and 8-16 weeks after ETI therapy. For PREFUL-derived ventilation and perfusion parameter extraction, two-dimensional coronal dynamic gradient-echo MR images were evaluated with an automated quantitative pipeline. T1- and T2-weighted MR images and PREFUL perfusion maps were visually assessed for semiquantitative Eichinger scores. Wilcoxon signed rank test compared clinical parameters and PREFUL values before and after ETI therapy. Correlation of parameters was calculated as Spearman ρ correlation coefficient. Results Twenty-three participants (median age, 18 years [IQR: 14-24.5 years]; 13 female) were included. Quantitative PREFUL parameters, Eichinger score, and clinical parameters (lung clearance index = 21) showed significant improvement after ETI therapy. Ventilation defect percentage of regional ventilation decreased from 18% (IQR: 14%-25%) to 9% (IQR: 6%-17%) (P = .003) and perfusion defect percentage from 26% (IQR: 18%-36%) to 19% (IQR: 13%-24%) (P = .002). Areas of matching normal (healthy) ventilation and perfusion increased from 52% (IQR: 47%-68%) to 73% (IQR: 61%-83%). Visually assessed perfusion scores did not correlate with PREFUL perfusion (P = .11) nor with ventilation-perfusion match values (P = .38). Conclusion The study demonstrates the feasibility of PREFUL MRI for semiautomated quantitative assessment of perfusion and ventilation changes in response to ETI therapy in people with CF.

ABSTRACT

OBJECTIVE: Refugees are frequently shown to have worse mental health outcomes than non-displaced populations. This fact is commonly attributed to traumatic pre-displacement experiences. While important, the focus on trauma risks overlooking the role socioeconomic living-conditions in different arrival and transit contexts can play in determining refugees' mental distress. Building on the ecological model of refugee distress, we investigate how social ecological conditions relate to the mental distress of Syrians in Lebanon and Turkey. Both countries present important spaces of arrival and transit for millions of displaced Syrians, each with a specific historical, political, social and economic context. METHODS: The empirical analysis is based on data gathered in early 2021 in face-to-face surveys among displaced Syrians in Lebanon (N = 1127) and Turkey (N = 1364). Individual mental distress is evaluated using the Patient Health Questionnaire (PHQ-8) score as the dependent variable in a multivariate regression analysis. RESULTS: Social ecological factors do not only differ in their extent of deprivation between Lebanon and Turkey. They also differ in their relationship with individual mental health outcomes. In Lebanon, limited access to the health care system and having family in the same city are major risk factors for elevated mental distress, whereas in Turkey, these are low education, poverty, unemployment as well as employment as day laborer. Discrimination and social isolation emerge as relevant predictors in both countries. CONCLUSION: Based on this analysis, we argue that a context-specific understanding of mental distress amidst the social ecology refugees face in countries of refuge and transit is necessary. This approach needs to be pursued to provide adequate support and alleviate refugees' mental distress both, in the country of first refuge and after possible onward migration. In addition to clinical implications, the study particularly highlights the important role anti-discrimination and social inclusion policies could play in promoting refugee mental health.

ABSTRACT

Purpose To develop an MRI-based model for clinically significant prostate cancer (csPCa) diagnosis that can resist rectal artifact interference. Materials and Methods This retrospective study included 2203 male patients with prostate lesions who underwent biparametric MRI and biopsy between January 2019 and June 2023. Targeted adversarial training with proprietary adversarial samples (TPAS) strategy was proposed to enhance model resistance against rectal artifacts. The automated csPCa diagnostic models trained with and without TPAS were compared using multicenter validation datasets. The impact of rectal artifacts on the diagnostic performance of each model at the patient and lesion levels was compared using the area under the receiver operating characteristic curve (AUC) and the area under the precision-recall curve (AUPRC). The AUC between models was compared using the DeLong test, and the AUPRC was compared using the bootstrap method. Results The TPAS model exhibited diagnostic performance improvements of 6% at the patient level (AUC: 0.87 vs 0.81, P < .001) and 7% at the lesion level (AUPRC: 0.84 vs 0.77, P = .007) compared with the control model. The TPAS model demonstrated less performance decline in the presence of rectal artifact-pattern adversarial noise than the control model (ΔAUC: -17% vs -19%, ΔAUPRC: -18% vs -21%). The TPAS model performed better than the control model in patients with moderate (AUC: 0.79 vs 0.73, AUPRC: 0.68 vs 0.61) and severe (AUC: 0.75 vs 0.57, AUPRC: 0.69 vs 0.59) artifacts. Conclusion This study demonstrates that the TPAS model can reduce rectal artifact interference in MRI-based csPCa diagnosis, thereby improving its performance in clinical applications.

ABSTRACT

Purpose To compare the image quality and diagnostic capability in detecting malignant liver tumors of low-dose CT (LDCT, 33% dose) with deep learning-based denoising (DLD) and standard-dose CT (SDCT, 100% dose) with model-based iterative reconstruction (MBIR). Materials and Methods In this prospective, multicenter, noninferiority study, individuals referred for liver CT scans were enrolled from three tertiary referral hospitals between February 2021 and August 2022. All liver CT scans were conducted using a dual-source scanner with the dose split into tubes A (67% dose) and B (33% dose). Blended images from tubes A and B were created using MBIR to produce SDCT images, whereas LDCT images used data from tube B and were reconstructed with DLD. The noise in liver images was measured and compared between imaging techniques. The diagnostic performance of each technique in detecting malignant liver tumors was evaluated by three independent radiologists using jackknife alternative free-response receiver operating characteristic analysis. Noninferiority of LDCT compared with SDCT was declared when the lower limit of the 95% CI for the difference in figure of merit (FOM) was greater than -0.10. Results A total of 296 participants (196 men, 100 women; mean age, 60.5 years ± 13.3 [SD]) were included. The mean noise level in the liver was significantly lower for LDCT (10.1) compared with SDCT (10.7) (P < .001). Diagnostic performance was assessed in 246 participants (108 malignant tumors in 90 participants). The reader-averaged FOM was 0.880 for SDCT and 0.875 for LDCT (P = .35). The difference fell within the noninferiority margin (difference, -0.005 [95% CI: -0.024, 0.012]). Conclusion Compared with SDCT with MBIR, LDCT using 33% of the standard radiation dose had reduced image noise and comparable diagnostic performance in detecting malignant liver tumors.

ABSTRACT

Over the last decade, clinical practice guidelines (CPGs) have become an important asset for daily life in healthcare organizations. Efficient management and digitization of CPGs help achieve organizational objectives and improve patient care and healthcare quality by reducing variability. However, digitizing CPGs is a difficult, complex task because they are usually expressed as text, and this often leads to the development of partial software solutions. At present, different research proposals and CPG-derived CDSS (clinical decision support system) do exist for managing CPG digitalization lifecycles (from modeling to deployment and execution), but they do not all provide full lifecycle support, making it more difficult to choose solutions or proposals that fully meet the needs of a healthcare organization. This paper proposes a method based on quality models to uniformly compare and evaluate technological tools, providing a rigorous method that uses qualitative and quantitative analysis of technological aspects. In addition, this paper also presents how this method has been instantiated to evaluate and compare CPG-derived CDSS by highlighting each phase of the CPG digitization lifecycle. Finally, discussion and analysis of currently available tools are presented, identifying gaps and limitations.

ABSTRACT

Purpose: Open reduction (OR) is usually required in developmental dysplasia of hip (DDH) for children below 24 months of age, those who failed to achieve a satisfactory reduction by the closed method. OR in this age group can be performed either through a medial or anterior approach. However, there is a paucity of literature and a lack of more substantial evidence regarding which approach (medial versus anterior) is superior for performing OR in this age group with minimal complications. Methods: Four databases (PubMed, Embase, Scopus, and Cochrane Library) were searched for relevant articles reporting outcomes and complication rates of DDH children less than 24 months undergone OR either through medial or anterior approach using pre-defined keywords. Data on avascular necrosis (AVN) rates, further corrective surgery (FCS) rates, and clinical and radiological grading using McKay clinical criteria and Severin radiological criteria were assessed. Meta-analysis was carried out using RevMan (Review Manager 5.4) software. Results: Five comparative studies, having a minimum of two-year follow-up, were included for final analysis. According to the MINORS tool assessment, all five studies were of good to high quality. Of 257 hips, 151 and 106 underwent OR through medial and anterior approaches, respectively. Our meta-analysis showed a statistically significant (p = 0.01) number of AVN cases with the anterior approach compared to the medial approach. The overall random effect showed the odds of having AVN with an anterior approach to be 2.27 (95% CI: 1.18,4.38) times more than the same with a medial approach. Regarding FCS rates, the meta-analysis depicted no significant difference between the two groups (p = 0.63). The two groups had no statistically significant difference regarding clinical and radiological outcomes using McKay and Severin criteria, respectively. Following surgery, improvement in the acetabular index from pre-operative value showed no statistically significant difference between the two groups (p = 0.48). Conclusions: Medial approach is safe and effective for OR of the hip in DDH up to 24 months of age. Our analysis showed that AVN rates are lower with a medial approach than the anterior approach, with similar clinical and radiological outcomes and rates of FCS. However, one should consider the surgeon's expertise while choosing between these approaches.

ABSTRACT

This article contributes a comparative review of social work in Canada and Scotland to international conversations about social work and the environment. The 'environmental question' of the 21st century is a radical challenge to social work developed in relation to the 'social question' of the 19th century. Work to begin to include the natural environment within high-income state social work can expect to encounter established infrastructures of thinking and doing that will be difficult to shift. We, therefore, compare guiding social work policy documents and identify points of tension that are likely to be shared across wealthy national contexts.
