RESUMO

Multiparametric MRI is the optimal primary investigation when prostate cancer is suspected, and its ability to rule in and rule out clinically significant disease relies on high-quality anatomical and functional images. Avenues for achieving consistent high-quality acquisitions include meticulous patient preparation, scanner setup, optimised pulse sequences, personnel training, and artificial intelligence systems. The impact of these interventions on the final images needs to be quantified. The prostate imaging quality (PI-QUAL) scoring system was the first standardised quantification method that demonstrated the potential for clinical benefit by relating image quality to cancer detection ability by MRI. We present the updated version of PI-QUAL (PI-QUAL v2) which applies to prostate MRI performed with or without intravenous contrast medium using a simplified 3-point scale focused on critical technical and qualitative image parameters. CLINICAL RELEVANCE STATEMENT: High image quality is crucial for prostate MRI, and the updated version of the PI-QUAL score (PI-QUAL v2) aims to address the limitations of version 1. It is now applicable to both multiparametric MRI and MRI without intravenous contrast medium. KEY POINTS: High-quality images are essential for prostate cancer diagnosis and management using MRI. PI-QUAL v2 simplifies image assessment and expands its applicability to prostate MRI without contrast medium. PI-QUAL v2 focuses on critical technical and qualitative image parameters and emphasises T2-WI and DWI.

RESUMO

The prevalence of diseases characterised by eosinophilia is on the rise, emphasising the importance of understanding the role of eosinophils in these conditions. Eosinophils are a subset of granulocytes that contribute to the body's defence against bacterial, viral, and parasitic infections, but they are also implicated in haemostatic processes, including immunoregulation and allergic reactions. They contain cytoplasmic granules which can be selectively mobilised and secrete specific proteins, including chemokines, cytokines, enzymes, extracellular matrix, and growth factors. There are multiple biological and emerging functions of these specialised immune cells, including cancer surveillance, tissue remodelling and development. Several oral diseases, including oral cancer, are associated with either tissue or blood eosinophilia; however, their exact mechanism of action in the pathogenesis of these diseases remains unclear. This review presents a comprehensive synopsis of the most recent literature for both clinicians and scientists in relation to eosinophils and oral diseases and reveals a significant knowledge gap in this area of research.

RESUMO

Machine learning analyses within the realm of oral cancer outcomes are relatively underexplored compared to other cancer types. This study aimed to assess the performance of machine learning algorithms in identifying oral cancer patients, utilizing microRNA expression data. In this study, we implemented this approach using a panel of oral cancer-associated microRNAs sourced from standard incisional biopsy specimens to identify cases of oral squamous cell carcinomas (OSCC). For the model development process, we used a dataset comprising 30 OSCC and 30 histologically normal epithelium (HNE) cases. We initially trained a logistic regression prediction model using 70 percent of the dataset, while reserving the remaining 30 percent for testing. Subsequently, the model underwent hyperparameter tuning resulting in enhanced performance metrics. The hyperparameter-tuned model exhibited high accuracy (0.894) and ROC AUC (0.898) in predicting OSCC. Testing the model on cases of potentially malignant disorders (OPMDs) revealed that leukoplakia with mild dysplasia was predicted as having a high risk of progressing to OSCC, emphasizing machine learning's advantage over histopathology in detecting early molecular changes. These findings underscore the necessity for further refinement, incorporating a broader set of variables to enhance the model's predictive capabilities in assessing the risk of oral potentially malignant disorders.

RESUMO

BACKGROUND AND OBJECTIVE: The Prostate Cancer Radiological Estimation of Change in Sequential Evaluation (PRECISE) recommendations standardise the reporting of prostate magnetic resonance imaging (MRI) in patients on active surveillance (AS) for prostate cancer. An international consensus group recently updated these recommendations and identified the areas of uncertainty. METHODS: A panel of 38 experts used the formal RAND/UCLA Appropriateness Method consensus methodology. Panellists scored 193 statements using a 1-9 agreement scale, where 9 means full agreement. A summary of agreement, uncertainty, or disagreement (derived from the group median score) and consensus (determined using the Interpercentile Range Adjusted for Symmetry method) was calculated for each statement and presented for discussion before individual rescoring. KEY FINDINGS AND LIMITATIONS: Participants agreed that MRI scans must meet a minimum image quality standard (median 9) or be given a score of 'X' for insufficient quality. The current scan should be compared with both baseline and previous scans (median 9), with the PRECISE score being the maximum from any lesion (median 8). PRECISE 3 (stable MRI) was subdivided into 3-V (visible) and 3-NonV (nonvisible) disease (median 9). Prostate Imaging Reporting and Data System/Likert ≥3 lesions should be measured on T2-weighted imaging, using other sequences to aid in the identification (median 8), and whenever possible, reported pictorially (diagrams, screenshots, or contours; median 9). There was no consensus on how to measure tumour size. More research is needed to determine a significant size increase (median 9). PRECISE 5 was clarified as progression to stage ≥T3a (median 9). CONCLUSIONS AND CLINICAL IMPLICATIONS: The updated PRECISE recommendations reflect expert consensus opinion on minimal standards and reporting criteria for prostate MRI in AS. PATIENT SUMMARY: The Prostate Cancer Radiological Estimation of Change in Sequential Evaluation (PRECISE) recommendations are used in clinical practice and research to guide the interpretation and reporting of magnetic resonance imaging for patients on active surveillance for prostate cancer. An international panel has updated these recommendations, clarified the areas of uncertainty, and highlighted the areas for further research.

RESUMO

Bilateral lower extremity inflammatory lymphedema (BLEIL) is a novel condition characterized by confluent erythema and painful edema prominent to the dorsum of the feet and ankles bilaterally following prolonged standing and marching, occurring most often in military recruits. Prolonged standing during the initial week of basic training is thought to cause venous congestion and subsequent inflammatory vasculitis. This condition may be misdiagnosed as bilateral cellulitis, prompting the initiation of unnecessary antibiotic therapy. Increased education and recognition of this new clinical entity would lead to the initiation of appropriate therapy and earlier symptom resolution and, thus, an earlier return to military training. Herein, we describe a small case series of Marine Corps recruit members undergoing their first week of basic training (i.e., "processing week") who developed bilateral lower extremity edema, erythema, and pain localized to the dorsum of the feet and the medial and lateral aspects of the ankles consistent with the diagnosis of BLEIL but were initially diagnosed with bilateral lower extremity cellulitis and received intravenous antimicrobial therapy. With prompt initiation of venous decongestive therapy with leg elevation, both patients had rapid symptom resolution and returned to basic training without any future episodes of symptoms. These cases add to the paucity of data on this clinical entity, illustrate the symptoms and demographics of BLEIL, and describe the importance of recognition and initiation of appropriate therapy.

RESUMO

BACKGROUND: The role of multiparametric magnetic resonance imaging (MRI) for detecting recurrent prostate cancer after radiotherapy is unclear. OBJECTIVE: To evaluate MRI and MRI-targeted biopsies for detecting intraprostatic cancer recurrence and planning for salvage focal ablation. DESIGN, SETTING, AND PARTICIPANTS: FOcal RECurrent Assessment and Salvage Treatment (FORECAST; NCT01883128) was a prospective cohort diagnostic study that recruited 181 patients with suspected radiorecurrence at six UK centres (2014 to 2018); 144 were included here. INTERVENTION: All patients underwent MRI with 5 mm transperineal template mapping biopsies; 84 had additional MRI-targeted biopsies. MRI scans with Likert scores of 3 to 5 were deemed suspicious. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: First, the diagnostic accuracy of MRI was calculated. Second, the pathological characteristics of MRI-detected and MRI-undetected tumours were compared using the Wilcoxon rank sum test and chi-square test for trend. Third, four biopsy strategies involving an MRI-targeted biopsy alone and with systematic biopsies of one to two other quadrants were studied. Fisher's exact test was used to compare MRI-targeted biopsy alone with the best other strategy for the number of patients with missed cancer and the number of patients with cancer harbouring additional tumours in unsampled quadrants. Analyses focused primarily on detecting cancer of any grade or length. Last, eligibility for focal therapy was evaluated for men with localised (≤T3bN0M0) radiorecurrent disease. RESULTS AND LIMITATIONS: Of 144 patients, 111 (77%) had cancer detected on biopsy. MRI sensitivity and specificity at the patient level were 0.95 (95% confidence interval [CI] 0.92 to 0.99) and 0.21 (95% CI 0.07 to 0.35), respectively. At the prostate quadrant level, 258/576 (45%) quadrants had cancer detected on biopsy. Sensitivity and specificity were 0.66 (95% CI 0.59 to 0.73) and 0.54 (95% CI 0.46 to 0.62), respectively. At the quadrant level, compared with MRI-undetected tumours, MRI-detected tumours had longer maximum cancer core length (median difference 3 mm [7 vs 4 mm]; 95% CI 1 to 4 mm, p < 0.001) and a higher grade group (p = 0.002). Of the 84 men who also underwent an MRI-targeted biopsy, 73 (87%) had recurrent cancer diagnosed. Performing an MRI-targeted biopsy alone missed cancer in 5/73 patients (7%; 95% CI 3 to 15%); with additional systematic sampling of the other ipsilateral and contralateral posterior quadrants (strategy 4), 2/73 patients (3%; 95% CI 0 to 10%) would have had cancer missed (difference 4%; 95% CI -3 to 11%, p = 0.4). If an MRI-targeted biopsy alone was performed, 43/73 (59%; 95% CI 47 to 69%) patients with cancer would have harboured undetected additional tumours in unsampled quadrants. This reduced but only to 7/73 patients (10%; 95% CI 4 to 19%) with strategy 4 (difference 49%; 95% CI 36 to 62%, p < 0.0001). Of 73 patients, 43 (59%; 95% CI 47 to 69%) had localised radiorecurrent cancer suitable for a form of focal ablation. CONCLUSIONS: For patients with recurrent prostate cancer after radiotherapy, MRI and MRI-targeted biopsy, with or without perilesional sampling, will diagnose cancer in the majority where present. MRI-undetected cancers, defined as Likert scores of 1 to 2, were found to be smaller and of lower grade. However, if salvage focal ablation is planned, an MRI-targeted biopsy alone is insufficient for prostate mapping; approximately three of five patients with recurrent cancer found on an MRI-targeted biopsy alone harboured further tumours in unsampled quadrants. Systematic sampling of the whole gland should be considered in addition to an MRI-targeted biopsy to capture both MRI-detected and MRI-undetected disease. PATIENT SUMMARY: After radiotherapy, magnetic resonance imaging (MRI) is accurate for detecting recurrent prostate cancer, with missed cancer being smaller and of lower grade. Targeting a biopsy to suspicious areas on MRI results in a diagnosis of cancer in most patients. However, for every five men who have recurrent cancer, this targeted approach would miss cancers elsewhere in the prostate in three of these men. If further focal treatment of the prostate is planned, random biopsies covering the whole prostate in addition to targeted biopsies should be considered so that tumours are not missed.

RESUMO

The development of different imaging modalities of the prostate has significantly improved tumor detection, patient risk stratification, and quality of care.Among these, multiparametric magnetic resonance imaging (mp-MRI) has emerged as the most sensitive tool.It is useful in the diagnosis, localization, risk stratification, and staging of clinically significant prostate cancer, PCa. As a result, mp-MRI of the prostate is recommended as the initial diagnostic test for men with suspected PCa. A multidisciplinary approach is crucial in the diagnosis and management of prostate cancer and mp-MRI plays a fundamental role in this scenario.While many aspects of image quality certainly fall within the purview of radiology, it is important to recognize that urologists must also be attentive to imaging quality when utilizing mp-MRI to facilitate PCa management. We present our viewpoint as urologists on how image quality impacts the management of men diagnosed with PCa andattempt to identify the factors that impact mp-MRI image quality, consequences of poor image quality, and finally suggestions for improvements.

RESUMO

BACKGROUND: Increasingly researchers are partnering with citizens and communities in research; less is known about research impacts of this engagement. EMBOLDEN is an evidence-informed, mobility-promoting intervention for older adults co-designed by a 26-person Strategic Guiding Council (SGC) of health/social service providers and older adult citizens. This study evaluated research partners' perceptions of engagement strategies, the engagement context, strengths, areas for improvement, as well as the impacts of the guiding council on older-adult identified priority areas. METHODS: This study was guided by developmental evaluation, working in partnership with four older adult SGC members who helped to set evaluation priorities, decide methods, and adapt patient-centred evaluation tools. Data sources included a questionnaire, focus groups and document analysis of meeting notes from 16 SGC meetings that took place between December 2019 and February 2022. A thematic approach to analysis guided the coding of focus group transcripts and SGC meeting notes. Convergent mixed methods guided the integration and presentation of qualitative and quantitative data sources in a joint display of evaluation results. RESULTS: Of 26 SGC members, nine completed the evaluation squestionnaire, and five participated in focus groups. Around two thirds of the SGC commonly attended each meeting. EMBOLDEN's SGC was structured to include a diverse group (across gender, ethnicity and discipline) of older adults and service providers, which was perceived as a strength. Engagement processes were perceived as inclusive and well-facilitated, which stimulated discussion at meetings. Advantages and disadvantages of engaging with the SGC virtually, as compared to in-person (as was the case for the first 3 SGC meetings) were also discussed. Impacts of the SGC were identified across preparatory, execution phase and translational stages of research. Impacts of SGC involvement on members were also described. CONCLUSION: Older adult research partners played an important role designing, implementing, and evaluating co-design approaches in this study. Older adults and service providers can make important contributions to the design, delivery and sharing results of health research through their lived expertise and connections to community. This project contributes to the growing field of citizen and community engagement in research by offering a participatory approach to engagement evaluation that considers diversity, satisfaction, and impact.


It is becoming common for researchers to ask patients and caregivers to become involved with their studies as partners. By partnering with people who have first-hand experience with a condition, researchers hope their studies will be more relevant, run efficiently and have more impact than studies designed by researchers alone. Over the last twenty years, there has been a significant increase in the number of published papers that involve patients and caregivers, but few papers mention what changed because of this involvement. Researchers need to know the best ways to involve patients and caregivers and the impact of doing so.This study aimed to find out how a council of older adults (OAs) and service providers (SPs) impacted a study about collaboratively designing and testing a mobility intervention. This study aimed to find out how council members felt about their involvement in this study, by asking them what went well and what could have been improved.This study used a questionnaire, focus groups and analyzed council meeting notes to inform this study. Four OA council members helped design the study, decide research methods, and adapt wording of questions (focus groups, questionnaire). Between 19% and 35% of council members completed evaluation activities. They felt the study strengths were the diversity of the council, and a welcoming environment for discussion. The council impacted how the study was designed, carried out and how results were shared. Results from this study can improve patient partnership engagement, experiences, and impacts in future studies.

RESUMO

Sarcoidosis is a systemic inflammatory disease that can cause granulomatous infiltration of almost all organs and tissues which allows for a wide variety of presentations that may overlap with other disease processes. Renal sarcoidosis is a much rarer site of extrapulmonary involvement and may present as hypercalcemia, tubular or glomerular dysfunction, and/or granulomatous interstitial nephritis. Prompt diagnosis of sarcoidosis is crucial for initiating appropriate treatment and avoiding organ dysfunction. Herein, we describe a case of an armed forces service member who developed extrapulmonary sarcoidosis and renal sarcoidosis with acute complications refractory to glucocorticoids requiring adalimumab. The case highlights and emphasizes a rare manifestation of extrapulmonary sarcoidosis, the importance of avoiding premature closure of the differential diagnosis to avoid diagnostic delay and treatment imitation, and the unique clinical reasoning that occurs in active-duty personnel where diagnoses and subsequent treatments can have career implications and affect the ability of the service member to maintain the ability to deploy worldwide.

RESUMO

Environmental mercury (Hg) contamination of the global tropics outpaces our understanding of its consequences for biodiversity. Knowledge gaps of pollution exposure could obscure conservation threats in the Neotropics: a region that supports over half of the world's species, but faces ongoing land-use change and Hg emission via artisanal and small-scale gold mining (ASGM). Due to their global distribution and sensitivity to pollution, birds provide a valuable opportunity as bioindicators to assess how accelerating Hg emissions impact an ecosystem's ability to support biodiversity, and ultimately, global health. We present the largest database on Neotropical bird Hg concentrations (n = 2316) and establish exposure baselines for 322 bird species spanning nine countries across Central America, South America, and the West Indies. Patterns of avian Hg exposure in the Neotropics broadly align with those in temperate regions: consistent bioaccumulation across functional groups and high spatiotemporal variation. Bird species occupying higher trophic positions and aquatic habitats exhibited elevated Hg concentrations that have been previously associated with reductions in reproductive success. Notably, bird Hg concentrations were over four times higher at sites impacted by ASGM activities and differed by season for certain trophic niches. We developed this synthesis via a collaborative research network, the Tropical Research for Avian Conservation and Ecotoxicology (TRACE) Initiative, which exemplifies inclusive, equitable, and international data-sharing. While our findings signal an urgent need to assess sampling biases, mechanisms, and consequences of Hg exposure to tropical avian communities, the TRACE Initiative provides a meaningful framework to achieve such goals. Ultimately, our collective efforts support and inform local, scientific, and government entities, including Parties of the United Nations Minamata Convention on Mercury, as we continue working together to understand how Hg pollution impacts biodiversity conservation, ecosystem function, and public health in the tropics.


RESúMEN: La contaminación ambiental por mercurio (Hg) en los trópicos supera nuestra comprensión de sus consecuencias para la biodiversidad. Los vacíos de conocimiento que existen sobre la exposición a la contaminación podrían ocultar las amenazas para la conservación en el Neotrópico: una región que alberga a más de la mitad de las especies del mundo, pero que enfrenta una continua intensificación de las emisiones de Hg y del cambio de uso del suelo por el avance de la minería de oro artesanal y de pequeña escala (MAPE). Debido a su distribución global y su sensibilidad a la contaminación, las aves brindan una oportunidad valiosa como bioindicadores para evaluar cómo las emisiones de Hg afectan la capacidad de un ecosistema para sustentar la biodiversidad y, en última instancia, la salud global. Presentamos la más grande base de datos sobre concentraciones de Hg en aves Neotropicales (n = 2,316) para establecer una línea base para los niveles de exposición a Hg en 322 especies de aves de nueve países de América Central, América del Sur, y el Caribe. Encontramos patrones de las concentraciones de Hg en aves de los trópicos que se asemejan a los de las regiones templadas: mostrando una bioacumulación consistente a través de grupos funcionales y una alta variación espaciotemporal. Las especies de aves que ocupan posiciones más altas en la cadena trófica y en hábitats acuáticos registraron concentraciones elevadas de Hg que podrían tener efectos negativos en su éxito reproductivo. Es importante resaltar que las concentraciones de Hg en las aves de los sitios afectados por la MAPE fueron cuatro veces más altas que las de los sitios control y además difirió por temporada para ciertos nichos tróficos. Desarrollamos esta síntesis a través de una red de investigación colaborativa, la Iniciativa de Investigación Tropical para la Conservación y Ecotoxicología Aviar (TRACE), que ejemplifica un intercambio de datos inclusivo, equitativo e internacional. Si bien nuestros hallazgos sugieren una necesidad urgente de evaluar los sesgos en el muestreo, los mecanismos, y las consecuencias de la exposición al Hg en las comunidades de aves tropicales, la Iniciativa TRACE proporciona un marco para abordar estos objetivos. Nuestro esfuerzo colectivo tiene como propósito respaldar y brindar información a las entidades locales, científicas, y gubernamentales, incluyendo las Partes de la Convención de Minamata de las Naciones Unidas sobre el Mercurio, mientras continuamos trabajando juntos para comprender cómo la contaminación por Hg en los trópicos puede afectar la salud pública, el funcionamiento de los ecosistemas, y la conservación de la biodiversidad.

RESUMO

Magnetic resonance imaging is the gold standard imaging modality for the diagnosis of prostate cancer (PCa). Image quality is a fundamental prerequisite for the ability to detect clinically significant disease. In this critical review, we separate the issue of image quality into quality improvement and quality assessment. Beginning with the evolution of technical recommendations for scan acquisition, we investigate the role of patient preparation, scanner factors, and more advanced sequences, including those featuring Artificial Intelligence (AI), in determining image quality. As means of quality appraisal, the published literature on scoring systems (including the Prostate Imaging Quality score), is evaluated. Finally, the application of AI and teaching courses as ways to facilitate quality assessment are discussed, encouraging the implementation of future image quality initiatives along the PCa diagnostic and monitoring pathway. EVIDENCE LEVEL: 3 TECHNICAL EFFICACY: Stage 3.

RESUMO

Background High variability in prostate MRI quality might reduce accuracy in prostate cancer detection. Purpose To prospectively evaluate the quality of MRI scanners taking part in the quality control phase of the global PRIME (Prostate Imaging Using MRI ± Contrast Enhancement) trial using the Prostate Imaging Quality (PI-QUAL) standardized scoring system, give recommendations on how to improve the MRI protocols, and establish whether MRI quality could be improved by these recommendations. Materials and Methods In the prospective clinical trial (PRIME), for each scanner, centers performing prostate MRI submitted five consecutive studies and the MRI protocols (phase I). Submitted data were evaluated in consensus by two expert genitourinary radiologists using the PI-QUAL scoring system that evaluates MRI diagnostic quality using five points (1 and 2 = nondiagnostic; 3 = sufficient; 4 = adequate, 5 = optimal) between September 2021 and August 2022. Feedback was provided for scanners not achieving a PI-QUAL 5 score, and centers were invited to resubmit new imaging data using the modified protocol (phase II). Descriptive comparison of outcomes was made between the MRI scanners, feedback provided, and overall PI-QUAL scores. Results In phase I, 41 centers from 18 countries submitted a total of 355 multiparametric MRI studies from 71 scanners, with nine (13%) scanners achieving a PI-QUAL score of 3, 39 (55%) achieving a score of 4, and 23 (32%) achieving a score of 5. Of the 48 (n = 71 [68%]) scanners that received feedback to improve, the dynamic contrast-enhanced sequences were those that least adhered to the Prostate Imaging Reporting and Data System, version 2.1, criteria (44 of 48 [92%]), followed by diffusion-weighted imaging (20 of 48 [42%]) and T2-weighted imaging (19 of 48 [40%]). In phase II, 36 centers from 17 countries resubmitted revised studies, resulting in a total of 62 (n = 64 [97%]) scanners with a final PI-QUAL score of 5. Conclusion Substantial variation in global prostate MRI acquisition parameters as a measure of quality was observed, particularly with DCE sequences. Basic evaluation and modifications to MRI protocols using PI-QUAL can lead to substantial improvements in quality. Clinical trial registration no. NCT04571840 Published under a CC BY 4.0 license.

RESUMO

BACKGROUND: Micronutrients are vital for general and oral health, and their potential anti-cancer properties are documented. We explore beneficial vitamins for oral potentially malignant disorders (OPMDs) and oral cancer (OC), assessing the therapeutic impacts of essential vitamin supplementation. METHODS: We systematically review evidence on vitamin supplementation's therapeutic effects for OPMDs and OC. Relevant studies were identified through comprehensive searches of MEDLINE, Evidence-Based Medicine, and Web of Science until 16 May 2023. All studies underwent risk of bias using criteria modified from the Office of Health Assessment and Translation (OHAT) tool. RESULTS: We analysed 80 papers. Vitamin K, studied in vitro, shows promising therapeutic potential. Vitamin C, investigated in vivo (animals and humans), demonstrated mixed animal results and generally positive human trial effects. Vitamin A's efficacy varied, with positive monotherapy or adjunct effects. Vitamins B and D showed therapeutic benefits. Oral cancer research was extensive, with a focus on oral lichen planus and oral leukoplakia among the 11 OPMDs. All bias levels were reported in 'selective reporting' and 'performance', except for "definitely high" in the 'selection', 'detection', and 'attrition/exclusion' domains. CONCLUSIONS: Evidence of vitamin interventions for OPMDs and OC ranges from mixed to promising. Standardizing the study design and outcomes would enhance future research.

RESUMO

INTRODUCTION: The Accreditation Council for Graduate Medical Education (ACGME) endorses evolving scholarly education regarding evidence-based medicine (EBM) and its clinical application in Internal Medicine (IM). The IM residents at Navy Medical Readiness and Training Center San Diego (NMRTC-SD) communicated the need for both increased ambulatory didactic sessions as well as a formal EBM curriculum. Prior to the academic year of 2021-2022, no formal ambulatory or EBM curriculum existed. In July 2021, an integrated EBM-ambulatory curriculum was implemented. METHODS:  A pre-curriculum needs assessment was performed and thereafter an eight-session integrated ambulatory-EBM curriculum was implemented in the 2021-2022 academic year. Faculty members facilitated small group discussions focused on a particular didactic topic and EBM principle and integrated the learning of both into one session. After each session, residents completed a feedback form. At the end of the year, a post-curriculum needs assessment was collected. KEY RESULTS: Thirty-four residents of all post-graduate years (PGY) levels participated from July 2021 to June 2022. Primary outcomes were satisfaction with the didactic portion of the curriculum, perception of receipt of adequate training in EBM principles, and perception of level of competency in practicing EBM principles. Overall, participants reported a substantial increase in satisfaction with didactic teaching and a large increase in the perceived competency in practicing EBM principles. CONCLUSION: This integrated didactic-EBM curriculum represents an effective method of incorporating didactic topics in IM with the teaching and application of EBM principles, which improved resident satisfaction with the curricula and self-perception of competency in critically appraising medical literature.

RESUMO

Background: Pre-exposure prophylaxis (PrEP) for HIV is underutilized, particularly among attendees of obstetrics and gynecology (Ob/Gyn) clinics. Lack of self-perception of HIV risk is a barrier to PrEP utilization, and a lack of understanding of community risk factors for HIV may contribute to that lack of self-perception of risk. Methods: Attendees of general Ob/Gyn clinics in New Orleans completed a survey assessing HIV knowledge, self-perception of HIV risk, and interest in PrEP. They reviewed a brief written educational intervention on demographic and behavioral risk factors for HIV and availability of PrEP. HIV knowledge, self-perception of HIV risk, and interest in PrEP were reassessed after the intervention. Results: One-hundred seventy individuals completed the survey. Eighty-five participants (50%) expressed initial interest in PrEP. Self-perception of risk of HIV acquisition was associated with interest in PrEP. Ten of 11 (90.9%) respondents who had high self-perceived risk of HIV were interested in PrEP, compared with 75 of 159 (47.2%) of those who had low self-perceived risk (p = 0.01). The association remained significant in a multivariate analysis. After the intervention, the number of those who perceived themselves to be at risk of HIV increased from 11 to 25 individuals (p < 0.01) and 20 of these (80%) were interested in PrEP. Knowledge of HIV risk factors increased (p < 0.01). The intervention did not significantly alter interest in PrEP. Conclusions: Self-perception of HIV risk was associated with interest in PrEP. A brief written educational intervention increased knowledge of HIV risk factors and increased self-perception of risk of HIV. The intervention did not translate to increased interest in PrEP.

RESUMO

PURPOSE: This study aimed to assess the image quality of apparent diffusion coefficient (ADC) maps derived from conventional diffusion-weighted MRI and fractional intracellular volume maps (FIC) from VERDICT MRI (Vascular, Extracellular, Restricted Diffusion for Cytometry in Tumours) in patients from the INNOVATE trial. The inter-reader agreement was also assessed. METHODS: Two readers analysed both ADC and FIC maps from 57 patients enrolled in the INNOVATE prospective trial. Image quality was assessed using the Prostate Imaging Quality (PI-QUAL) score and a subjective image quality Likert score (Likert-IQ). The image quality of FIC and ADC were compared using a Wilcoxon Signed Ranks test. The inter-reader agreement was assessed with Cohen's kappa. RESULTS: There was no statistically significant difference between the PI-QUAL score for FIC datasets compared to ADC datasets for either reader (p = 0.240 and p = 0.614). Using the Likert-IQ score, FIC image quality was higher compared to ADC (p = 0.021) as assessed by reader-1 but not for reader-2 (p = 0.663). The inter-reader agreement was 'fair' for PI-QUAL scoring of datasets with FIC maps at 0.27 (95% confidence interval; 0.08-0.46) and ADC datasets at 0.39 (95% confidence interval 0.22-0.57). For Likert scoring, the inter-reader agreement was also 'fair' for FIC maps at 0.38 (95% confidence interval; 0.10-0.65) and substantial for ADC maps at 0.62 (95% confidence interval; 0.39-0.86). CONCLUSION: Image quality was comparable for FIC and ADC. The inter-reader agreement was similar when using PIQUAL for both FIC and ADC datasets but higher for ADC maps compared to FIC maps using the image quality Likert score.
