Footprints in the scan: reducing the carbon footprint of diagnostic tools in urology.

PURPOSE OF REVIEW: There is an ever-growing focus on climate change and its impact on our society. With healthcare contributing a sizeable proportion of carbon emissions, the sector has a duty to address its environmental impact. We highlight the recent progress, current challenges, and future prospects for reducing the carbon footprint in diagnostic urology, specifically for imaging, without compromising patient care. RECENT FINDINGS: The review is separated into four key areas of recent research: the design of a green radiology department, considering both infrastructural as well as behavioural changes that promote sustainability; individual scanners, where we provide an update on recent technological advancements and changes in behaviour that may enhance sustainable use; responsible resource allocation, where it is important to derive the maximal benefit for patients through the smallest use of resources; the recent research regarding single versus reusable urologic endoscopes as a case example. SUMMARY: We offer an overview of the present sustainability landscape in diagnostic urology with the aim of encouraging additional research in areas where existing practices may be challenged. To protect the environment, attention is drawn to both more simple steps that can be taken as well as some more complex and expensive ones.

PI-QUAL version 2: an update of a standardised scoring system for the assessment of image quality of prostate MRI.

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.

International Variations in Surgical Quality of Care in Men With Prostate Cancer: Results From the TrueNTH Global Registry.

PURPOSE: Functional problems such as incontinence and sexual dysfunction after radical prostatectomy (RP) are important outcomes to evaluate surgical quality in prostate cancer (PC) care. Differences in survival after RP between countries are known, but differences in functional outcomes after RP between providers from different countries are not well described. METHODS: Data from a multinational database of patients with PC (nonmetastatic, treated by RP) who answered the EPIC-26 questionnaire at baseline (before RP, T0) and 1 year after RP (T1) were used, linking survey data to clinical information. Casemix-adjusted incontinence and sexual function scores (T1) were calculated for each country and provider on the basis of regression models and then compared using minimally important differences (MIDs). RESULTS: A total of 21,922 patients treated by 151 providers from 10 countries were included. For the EPIC-26 incontinence domain, the median adjusted T1 score of countries was 76, with one country performing more than one MID (for incontinence: 6) worse than the median. Eighteen percent of the variance (R2) of incontinence scores was explained by the country of the providers. The median adjusted T1 score of sexual function was 33 with no country performing perceivably worse than the median (more than one MID worse), and 34% (R2) of the variance of the providers' scores could be explained by country. CONCLUSION: To our knowledge, this is the first comparison of functional outcomes 1 year after surgical treatment of patients with PC between different countries. Country is a relevant predictor for providers' incontinence and sexual function scores. Although the results are limited because of small samples from some countries, they should be used to enhance cross-country initiatives on quality improvement in PC care.

Social Capital as a Framework to Address Organizational Climate Change Policy.

PURPOSE: To examine state Area Agencies on Aging (AAAs) in Pennsylvania for services they provide to older adults regarding extreme events and how readiness can be captured through social networks and policies at the local, state, and federal levels. METHOD: Using an online survey, 79% of AAA directors answered questions describing perceptions and actions related to social capital and its influence on policy. RESULTS: AAAs acknowledged weather/temperature changes impact the need to prepare for common scenarios of extreme weather, temperature, and flooding. AAAs reported major social connections with county government and one state agency, with limited connections with federal agencies. CONCLUSION: Multiple opportunities exist for AAAs to consider climate change in expansion efforts, specifically regarding health care. Geriatric nurses can play a key role in expansion, advocacy, and policy development for AAAs that serve older adults in the context of climate change.

Urinary and Sexual Impact of Robotic Radical Prostatectomy: Reporting of Patient-reported Outcome Measures in the First Year after Radical Prostatectomy in a Contemporary Multicentre Cohort in the United Kingdom.

Background and objective: Radical prostatectomy (RP) is an established treatment for localised prostate cancer that can have a significant impact on urinary and sexual function, with recovery over time. Our aim was to describe functional recovery in the first year after RP, reporting descriptive outcomes alongside validated patient-reported outcome measure scores (Expanded Prostate Cancer Index Composite, EPIC-26). Methods: Men undergoing RP between September 2015 and November 2019 completed EPIC-26 at baseline and 1, 3, 6, and 12 mo. Key findings and limitations: Overall, 2030 men consented to participation, underwent RP, and completed EPIC-26. At baseline, 97% were pad-free (1928/1996; 95% confidence interval [CI] 96-97%) and 77% were leak-free and pad-free (1529/1996; 95% CI 75-78), with a median EPIC-26 incontinence domain score of 100 (interquartile range [IQR] 86-100). At 12 mo, 65% were pad-free (904/1388; 95% CI 63-68%) and 42% were leak-free and pad-free (583/1388; 95% CI 39-45%), with a median EPIC-26 score of 76 (IQR 61-100). While one in three men reported wearing a pad at 12 mo, fewer than one in ten men needed more than 1 pad/d. At baseline, 1.9% reported a "moderate or big problem" with urine leakage, which increased to 9.7% at 12 mo. At baseline, the median sexual domain score among 1880 men was 74 (IQR 43-92) and 52% had erections sufficient for intercourse without medication (975/1880; 95% CI 50-54%). Among these 975 men, 630 responded at 12 mo, of whom 17% reported sufficient erections for intercourse (105/630; 95% CI 14-20%), without medication in 6% (37/630; 95% CI 4-8%) and needing medication in 11% (68/630; 95% CI 9-13%); the median EPIC-26 domain score was 26 (IQR 13-57). Conclusions and clinical implications: Reporting of functional outcomes after RP in terms of easily understood concepts such as pad-free and leak-free status, and erections with and with medication, alongside the classical report using EPIC-26 domain scores, increases the understanding of RP recovery patterns over the first year. Patient summary: At 12 months after surgery for prostate cancer, one in ten men reported a moderate or big problem with urine leakage and one in five men reported sufficient erections.

Applying Machine Learning for Enhanced MicroRNA Analysis: A Companion Risk Tool for Oral Squamous Cell Carcinoma in Standard Care Incisional Biopsy.

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.

Eosinophils in Oral Disease: A Narrative Review.

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.

PRECISE Version 2: Updated Recommendations for Reporting Prostate Magnetic Resonance Imaging in Patients on Active Surveillance for Prostate Cancer.

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.

Inflammatory Lymphedema Masquerading as Bilateral Cellulitis: A Military Dilemma.

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.

The Role of Multiparametric MRI and MRI-targeted Biopsy in the Diagnosis of Radiorecurrent Prostate Cancer: An Analysis from the FORECAST Trial.

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.

Prostate MRI and image quality: The urologist's perspective.

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.

The ELSI Virtual Forum, 30 Years of the Genome: Integrating and Applying ELSI Research.

Evaluating the impact of engaging older adults and service providers as research partners in the co-design of a community mobility-promoting program: a mixed methods developmental evaluation study.

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.

Mercury in Neotropical birds: a synthesis and prospectus on 13 years of exposure data.

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. Total mercury (THg) concentrations (µg/g) and sample sizes of birds across Central America, South America, and the West Indies from 2007­2023.

Diagnosing Extrapulmonary Sarcoidosis and the Implications of Diagnosis on Military Service.

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.

The Role of Vitamins in Oral Potentially Malignant Disorders and Oral Cancer: A Systematic Review.

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.

Longitudinal Integrated Ambulatory, Didactic, and Evidenced-Based Medicine Curriculum in Internal Medicine.

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.
