Digital biomarkers: 3PM approach revolutionizing chronic disease management — EPMA 2024 position

AbstractNon-communicable chronic diseases (NCDs) have become a major global health concern. They constitute the leading cause of disabilities, increased morbidity, mortality, and socio-economic disasters worldwide.Medical condition-specific digital biomarker (DB) panels have emerged as valuable tools to manage NCDs. DBs refer to the measurable and quantifiable physiological, behavioral, and environmental parameters collected for an individual through innovative digital health technologies, including wearables, smart devices, and medical sensors. By leveraging digital technologies, healthcare providers can gather real-time data and insights, enabling them to deliver more proactive and tailored interventions to individuals at risk and patients diagnosed with NCDs.Continuous monitoring of relevant health parameters through wearable devices or smartphone applications allows patients and clinicians to track the progression of NCDs in real time. With the introduction of digital biomarker monitoring (DBM), a new quality of primary and secondary healthcare is being offered with promising opportunities for health risk assessment and protection against health-to-disease transitions in vulnerable sub-populations. DBM enables healthcare providers to take the most cost-effective targeted preventive measures, to detect disease developments early, and to introduce personalized interventions. Consequently, they benefit the quality of life (QoL) of affected individuals, healthcare economy, and society at large.DBM is instrumental for the paradigm shift from reactive medical services to 3PM approach promoted by the European Association for Predictive, Preventive, and Personalized Medicine (EPMA) involving 3PM experts from 55 countries worldwide. This position manuscript consolidates multi-professional expertise in the area, demonstrating clinically relevant examples and providing the roadmap for implementing 3PM concepts facilitated through DBs.

Same evidence different recommendations: a methodological assessment of transatlantic guidelines for the management of valvular heart disease.

To identify methodological variations leading to varied recommendations between the American College of Cardiology (ACC)/American Heart Association (AHA) and the European Society of Cardiology (ESC)/European Association for Cardio-Thoracic Surgery (EACTS) valvular heart disease (VHD) Guidelines, and to suggest foundational steps towards standardizing guideline development. An in-depth analysis was conducted to evaluate the methodologies used in developing the Transatlantic Guidelines for managing VHD. The evaluation was benchmarked against the standards proposed by the Institute of Medicine. Substantial discrepancies were noted in the methodologies utilized in development processes, including writing committee composition, evidence evaluation, conflict of interest management, and voting processes. Furthermore, despite their mutual differences, both methodologies also demonstrate notable deviations from the IOM standards in several essential areas, including literature review and evidence grading. These dual variances likely influenced divergent treatment recommendations. For example, the ESC/EACTS recommends transcatheter edge-to-edge repair (TEER) for patients ineligible for mitral valve surgery, while the ACC/AHA recommends TEER based on anatomy, regardless of surgical risk. ESC/EACTS guidelines recommend a mechanical aortic prosthesis for patients under 60, while ACC/AHA guidelines recommend it for patients under 50. Notably, the ACC/AHA and ESC/EACTS guidelines have differing age cut-offs for surgical over transcatheter aortic valve replacement (<65 and <75 years, respectively). Variations in methodologies for developing CPGs have resulted in different treatment recommendations that may significantly impact global practice patterns. Standardization of essential processes is vital to increase the uniformity and credibility of CPGs, ultimately improving healthcare quality, reducing variability and enhancing trust in modern medicine.

Which men benefit from prostate cancer screening? Prostate cancer mortality by subgroup in the European Randomised Study of Screening for Prostate Cancer.

To evaluate whether a subgroup of men can be identified that would benefit more from screening than others. This retrospective cohort study was based on three European Randomised Study of Screening for Prostate Cancer (ERSPC) centres, Finland, the Netherlands and Sweden. We identified 126 827 men aged 55-69 years in the study who were followed for maximum of 16 years after randomisation. The primary outcome was prostate cancer (PCa) mortality. We analysed three age groups 55-59, 60-64 and 65-69 years and PCa cases within four European Association of Urology (EAU) risk groups: low, intermediate, high risk, and advanced disease. The hazard ratio (HR) for PCa mortality in the screening arm relative to the control arm for men aged 55-59 years was 0.96 (95% confidence interval [CI] 0.75-1.24) in Finland, 0.70 (95% CI 0.44-1.12) in the Netherlands and 0.42 (95% CI 0.24-0.73) in Sweden. The HR for men aged 60-64 years was 1.03 (95% CI 0.77-1.37) in Finland, 0.76 (95% CI 0.50-1.16) in the Netherlands and 0.97 (95% CI 0.64-1.48) in Sweden. The HR for men aged 65-69 years was 0.80 (95% CI 0.62-1.03) in Finland and 0.57 (95% CI 0.38-0.83) in the Netherlands, and this age group was absent in Sweden. In the EAU risk group analysis, PCa mortality rates were materially lower for men with advanced disease at diagnosis in all three countries: 0.67 (95% CI 0.56-0.82) in Finland, 0.28 (95% CI 0.18-0.44) in the Netherlands, and 0.48 (95% CI 0.30-0.78) in Sweden. We were unable to unequivocally identify the optimal age group for screening, as mortality reduction differed among centres and age groups. Instead, the screening effect appears to depend on screening duration, and the number and frequency of screening rounds. PCa mortality reduction by screening is largely attributable to stage shift.

Definition and Management of Arrhythmia-induced Cardiomyopathy: Findings from the European Heart Rhythm Association Survey.

Arrhythmia-induced Cardiomyopathy (AiCM) represents a subtype of acute heart failure (HF) in the context of sustained arrhythmia. Clear definitions and management recommendations for AiCM are lacking. The European Heart Rhythm Association Scientific Initiatives Committee (EHRA SIC) conducted a survey to explore the current definitions and management of patients with AiCM among European and non-European electrophysiologists. A 25-item online questionnaire was developed and distributed among EP specialists on the EHRA SIC website and on social media between September 4th and October 5th 2023. Of the 206 respondents, 16% were female and 61% were between 30-49 years old. Most of the respondents were EP-Specialists (81%) working at University Hospitals (47%). While most participants (67%) agreed that AiCM should be defined as a left ventricular ejection fraction (LVEF) impairment after new onset of an arrhythmia, only 35% identified a specific LVEF drop to diagnose AiCM with a wide range of values (5-20% LVEF drop). Most respondents considered all available therapies: catheter ablation(93%), electrical cardioversion(83%), antiarrhythmic drugs (76%) and adjuvant HF treatment(76%). 83% of respondents indicated that adjuvant HF treatment should be started at first HF diagnosis prior to antiarrhythmic treatment and 84% agreed it should be stopped within six months after LVEF normalization. Responses for the optimal time point for the first LVEF reassessment during follow-up varied markedly (1 day-6 months after antiarrhythmic treatment). This EHRA Survey reveals varying practices regarding AiCM among physicians, highlighting a lack of consensus and heterogenous care of these patients.

Abstract PO5-19-02: I-PREPARE: International Prospective REgistry on Pre-pectorAl breast Reconstruction (EUBREAST 11R-NCT 05817175)

Abstract Background: Despite the progressive de-escalation of breast cancer (BC) surgery, mastectomy rates remain around 30-40%. Furthermore, up to 1/3 of BC patients undergo a contralateral risk-reducing mastectomy and around 40% of mutation carriers choose a bilateral intervention. To date, immediate breast reconstruction (IBR) with implants is the most commonly performed reconstructive procedure. After an initial experience with implants in subcutaneous positioning under the mastectomy flap in the seventies, this technique was abandoned due to a high rate of implant loss (28%), flap necrosis (13.5%) and capsular contracture (56%). For this reason, the positioning of the implant under the pectoralis major has become the standard of care. However, over time surgical techniques and implants have improved, resulting in decreasing implant loss, flap necrosis and capsular contracture rates. Moreover, biological/synthetic meshes have been used to cover the implant placed over the pectoralis major, thus avoiding to mobilize the muscle with some benefits in terms of reduced complications (no animation deformity, no chronic pain, no loss of muscular function), patients’ wellbeing, postoperative pain and recovery. Additionally, recent literature reported encouraging results with polyurethane breast implants in pre-pectoral positioning without any kind of implant coverage. Although these procedures are considered safe they were not evaluated in prospective randomized trials. In 2019 a joint consensus on pre-pectoral breast reconstruction (PBR) clearly recommended to properly audit the results in terms of surgical complications and patient-reported outcomes. Based on these premises the EUBREAST (European Breast Cancer Research Association of Surgical Trialists, www.eubreast.org) study group decided to launch a prospective international cohort study aimed at comparatively evaluating data on different surgical techniques of PBR with or without PMRT. Therefore, we will prospectively evaluate the utilization of PBR, including surgical, oncological, aesthetic and patients’ satisfaction and quality of life outcomes related to each type of surgical technique and the interaction with post-mastectomy radiation therapy (PMRT). Eligibility criteria: - Female patients age≥18 years - Signed informed consent - Patients undergoing mono/bilateral therapeutic mastectomy and immediate PBR Exclusion criteria - Patients not suitable for surgical treatment - Patients undergoing subpectoral reconstruction, reconstruction with tissue expander or autologous IBR Specific aims: The primary endpoint is implant-loss at 3 months defined as the unplanned removal or loss of the implant, as a result of infection or any other complication Secondary endpoints are infection, re-admission and re-operation rates, quality of life evaluated through BREASTQ Breast Reconstruction Module and EQ-5D-5L questionnaires on an App for patients before and after breast reconstruction at 6, 12, 24 months, early onset complication at 3 months, late-onset complications at 6, 12, 24 months, further surgery at 24 months, time to adjuvant therapy. Tertiary endpoints are further surgery, loco-regional recurrence, disease free survival, breast cancer specific survival, distant-disease free survival, overall survival, development of seroma/breast implant-associated anaplastic cell lymphoma. Statistics: We will use a single-arm design to assess the surgical safety of PBR through implant loss rate at 3 months which is expected to be ≤9% based on previous literature; 12% or greater will be regarded as unacceptably high. The assessment will be based on 1,112 patients. For this sample size calculation, power was set to 90%, and the two-sided alpha was set to 0.05. Allowing for a 10% loss to follow-up at 3 months, we aim at recruiting 1,236 patients. Accrual has not started yet.

The clinician's view on the advantages and contradictions of the new nomenclature of steatotic liver disease: A review

In September 2023, the European Association for the Study of the Liver (EASL) updated the disease nomenclature for non-alcoholic (metabolically associated) fatty liver disease. The goals of the revision were to increase awareness among health care professionals, civil society and patients about the disease, its course, treatment and outcomes; combating stigma; focusing on the initial etiological factor, including the main (cardiometabolic) risk of disease progression; improved diagnosis based on disease biomarkers; positive impact on the potency to search for new drugs; the ability to provide personalized medical care. The terms “non-alcoholic” and “fatty” were considered stigmatizing, and therefore, it was proposed to use the term steatotic liver disease (SLD) as the name of this nosology. The terms non-alcoholic fatty liver disease (NAFLD) or metabolic associated fatty liver disease (MAFLD) have been replaced by the term metabolic dysfunction-associated steatotic liver disease (MASLD). In the case of being combined with an alcohol factor, a diagnosis in which metabolic dysfunction is combined with alcoholic liver disease is referred to as MetALD. The fundamental principle in the diagnosis of MASLD is the presence of at least one of the cardiometabolic risk factors. Alcohol consumption interacts with cardiometabolic risk factors and increases the risk of SLD decompensation. The term nonalcoholic steatohepatitis (NASH), according to the new nomenclature, has been replaced by the term metabolic dysfunction-associated steatohepatitis (MASH). The adoption of the new nomenclature should help to increase awareness about the disease, its course and outcomes, as well as improve the quality of diagnosis and treatment.

Questions and Answers about the British Association for the Study of Religions (BASR)

The Association introduces you to the various guilds, societies, and organizations where scholars carry out their work. In this issue, we learned a bit about the British Association for the Study of Religion (BASR) from their secretary Suzanne Owen. Founded in 1954, BASR is a member association of the International Association for the History of Religions and of the European Association for the Study of Religions. Answers in our exchange were provided by Suzanne Owen (Secretary of the BASR) and reviewed by Stephen Gregg (President of the BASR).

Normal-Flow Low-Gradient AorticStenosis: Comparing the U.S. and European Guidelines.

Patients with normal-flow low-gradient (NFLG) severe aortic stenosis present both diagnostic and management challenges, with debate about the whether this represents true severe stenosis and the need for valve replacement. Studies exploring the natural history without intervention have shown similar outcomes of patients with NFLG severe aortic stenosis to those with moderate aortic stenosis and better outcomes after valve replacement than those with low-flow low-gradient severe aortic stenosis. Most studies (all observational) have shown that aortic valve replacement was associated with a survival benefit vs surveillance. Based on available data, the European Society of Cardiology/European Association for Cardio-Thoracic Surgery guidelines and European Association of Cardiovascular Imaging/American Society of Echocardiography suggest that these patients are more likely to have moderate aortic stenosis. This clinical entity is not mentioned in the American Heart Association/American College of Cardiology guidelines. Here we review the definition of NFLG severe aortic stenosis, potential diagnostic algorithms and points of error, the data supporting different management strategies, and the differing guidelines and outline the unanswered questions in the diagnosis and management of these challenging patients.

Embolic strokes of undetermined source: a clinical consensus statement of the ESC Council on Stroke, the European Association of Cardiovascular Imaging and the European Heart Rhythm Association of the ESC.

One in six ischaemic stroke patients has an embolic stroke of undetermined source (ESUS), defined as a stroke with unclear aetiology despite recommended diagnostic evaluation. The overall cardiovascular risk of ESUS is high and it is important to optimize strategies to prevent recurrent stroke and other cardiovascular events. The aim of clinicians when confronted with a patient not only with ESUS but also with any other medical condition of unclear aetiology is to identify the actual cause amongst a list of potential differential diagnoses, in order to optimize secondary prevention. However, specifically in ESUS, this may be challenging as multiple potential thromboembolic sources frequently coexist. Also, it can be delusively reassuring because despite the implementation of specific treatments for the individual pathology presumed to be the actual thromboembolic source, patients can still be vulnerable to stroke and other cardiovascular events caused by other pathologies already identified during the index diagnostic evaluation but whose thromboembolic potential was underestimated. Therefore, rather than trying to presume which particular mechanism is the actual embolic source in an ESUS patient, it is important to assess the overall thromboembolic risk of the patient through synthesis of the individual risks linked to all pathologies present, regardless if presumed causally associated or not. In this paper, a multi-disciplinary panel of clinicians/researchers from various backgrounds of expertise and specialties (cardiology, internal medicine, neurology, radiology and vascular surgery) proposes a comprehensive multi-dimensional assessment of the overall thromboembolic risk in ESUS patients through the composition of individual risks associated with all prevalent pathologies.

European association of perinatal medicine (EAPM) position statement: Screening, diagnosis and management of congenital anomalies of the umbilical cord

Congenital anomalies of the umbilical cord are associated with an increased risk of pregnancy and perinatal complications. Some anomalies of the cord have a higher prevalence than other fetal structural anomalies. The most common anomalies are the absence of an umbilical artery and velamentous insertion of the cord (with or without vasa previa). These anomalies, even when not associated with fetal structural defects, increase the risk of adverse perinatal outcome including, fetal growth restriction and stillbirth. In the absence of prenatal diagnosis, vasa previa is associated with the highest perinatal morbidity and mortality of all congenital anomalies of the umbilical cord. Most cases can be detected by ultrasound from the beginning of the second trimester and should be included in the routine mid-pregnancy ultrasound examination. Documentation should include cord insertion site, number of vessels in the cord, and if other pathologies have been detected. Pregnancies at increased risk of velamentous cord insertion should be screened for vasa previa using transvaginal ultrasound and colour Doppler imaging. If a velamentous cord insertion or isolated single umbilical artery is detected, individualised follow-up during pregnancy and tailored obstetric management are indicated.

A Comparison of Globally Applied Prognostic Risk Groups and the Prevalence of Metastatic Disease on Prostate-specific Membrane Antigen Positron Emission Tomography in Patients with Newly Diagnosed Prostate Cancer

BackgroundVarious risk classification systems (RCSs) are used globally to stratify newly diagnosed patients with prostate cancer (PCa) into prognostic groups. ObjectiveTo compare the predictive value of different prognostic subgroups (low-, intermediate-, and high-risk disease) within the RCSs for detecting metastatic disease on prostate-specific membrane antigen (PSMA) positron emission tomography (PET)/computed tomography (CT) for primary staging, and to assess whether further subdivision of subgroups would be beneficial. Design, setting, and participantsPatients with newly diagnosed PCa, in whom PSMA-PET/CT was performed between 2017 and 2022, were studied retrospectively. Patients were stratified into risk groups based on four RCSs: European Association of Urology, National Comprehensive Cancer Network (NCCN), Cambridge Prognostic Group (CPG), and Cancer of the Prostate Risk Assessment. Outcome measurements and statistical analysisThe prevalence of metastatic disease on PSMA-PET/CT was compared among the subgroups within the four RCSs. Results and limitationsIn total, 2630 men with newly diagnosed PCa were studied. Any metastatic disease was observed in 35% (931/2630) of patients. Among patients classified as having intermediate- and high-risk disease, the prevalence of metastases ranged from approximately 12% to 46%. Two RCSs further subdivided these groups. According to the NCCN, metastatic disease was observed in 5.8%, 13%, 22%, and 62% for favorable intermediate-, unfavorable intermediate-, high-, and very-high-risk PCa, respectively. Regarding the CPG, these values were 6.9%, 13%, 21%, and 60% for the corresponding risk groups. ConclusionsThis study underlines the importance of nuanced risk stratification, recommending the further subdivision of intermediate- and high-risk disease given the notable variation in the prevalence of metastatic disease. PSMA-PET/CT for primary staging should be reserved for patients with unfavorable intermediate- or higher-risk disease. Patient summaryThe use of various risk classification systems in patients with prostate cancer helps identify those at a higher risk of having metastatic disease on prostate-specific membrane antigen positron emission tomography/computed tomography for primary staging.

The Political Life of Research Ethics Committees And What It Means for Ethnographic Research

This review discusses three pieces of work, that is, a conference panel and two books, that deal with the role of research ethics committees (RECs) in regulating biomedical research and medical anthropological research. We summarise the papers and conversations of a panel we convened on this topic during the 2020 European Association for Social Anthropologists (EASA) conference. We review two relatively recent books which discuss the role of RECs in biomedical research: Adam Hedgecoe’s (2020) Trust in the System: Research Ethics Committees and the Regulation of Biomedical Research, and Salla Sariola and Bob Simpson’s (2019) Research as Development: Biomedical Research, Ethics, and Collaboration in Sri Lanka. Finally, we consider how the review that RECs outside academic institutions perform is inadequate for ethnographic research, including that involving prospective participants who may lack capacity to consent. We conclude that undertaking the research ethics review internally (i.e., under university RECs) would be a first step forward in reclaiming ethnographic research ethical conversations.

Peri- and post-operative outcomes of robot-assisted radical cystectomy after the implementation of the EAU guidelines recommendations for collecting and reporting complications at a high-volume referral center.

No studies relied on a standardized methodology to collect postoperative complications after robot-assisted radical cystectomy (RARC). The aim of our study was to evaluate peri- and post-operative outcomes of patients undergoing RARC adhering to the European Association of Urology (EAU) recommendations for reporting surgical outcomes and using a long postoperative follow-up. 246 patients who underwent RARC with intracorporal urinary diversion at a single tertiary referral center with a postoperative follow-up ≥ 1year for survivors. Postoperative outcomes were collected prospectively by interviews done by medical doctors. Complications were scored using the Clavien-Dindo classification (CD), grouped by type and severity (severe: CD score ≥ 3). We described peri- and post-operative outcomes and complication chronological distribution. Overall, 16 (6.5%) and 225 patients (91%) experienced intraoperative and postoperative complications, respectively. Moreover, 139 (57%) experienced severe complications. The most common any-grade and severe complications were infectious (72%) and genitourinary (35%), respectively. Overall, 52% of complications (358/682) occurred within 10days from surgery, and 51% of severe complications (106/207) occurred within 35days. However, 13% of complications (90/682) and 28% of severe complications (59/207) occurred 3months after surgery. The earliest complications were fever of unknown origins and paralytic ileus (median time-to-complication [mTTC]: 4days), the latest complications were urinary tract infection (mTTC: 40days) and hydronephrosis/ureteral obstruction (mTTC: 70days). The rate of postoperative complications after RARC is > 90% when a standardized collection method and a long follow-up is implemented. These results should be used to identify potential areas of improvement and for preoperative patient counseling.

Is there a "European Paediatrics"?

The journey from birth to adulthood is paved with threats to health and wellbeing, rendering this age group with its invaluable future potential particularly vulnerable. Therefore, children and adolescents deserve medical attention of the highest professional level based on solid, well founded training guidelines, the availability of a well-coordinated platform for the continuous acquisition of knowledge, exchange of ideas, and collaboration on research and clinical projects, and comprehensive continuing education. For the European region these crucial specifications are met to varying degrees by three major paediatric organisations: the European Academy of Paediatrics (EAP) with the European Board of Paediatrics (EBP) as the paediatric section of the European Union of Medical Specialists (UEMS PS), the European Paediatric Association (EPA/UNEPSA) and the European Confederation of Primary Care Paediatricians (ECPCP). A major goal of this paper is to call for the closest possible collaboration between these organizations in advocating for the health and rights of European children and adolescents and in effectively fostering the paediatric profession with a strong, unified voice.

Systematic evaluation of Merkel cell carcinoma clinical practice guidelines using the AGREE II instrument

Merkel cell carcinoma (MCC) is a rare type of skin cancer that requires a multidisciplinary approach with a variety of specialists for management and treatment. Clinical practice guidelines (CPGs) have recently been established to standardize management algorithms. The objective of this study was to appraise such CPGs via the Appraisal of Guidelines for Research and Evaluation (AGREE II) instrument. Eight CPGs were identified via systematic literature search following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria. Four appraisers trained in AGREE II protocols evaluated each CPG and deemed two CPGs as high quality, five as moderate quality, and one as low quality. Intraclass correlation coefficients (ICCs) were calculated to verify reviewer consistency as excellent, good, and moderate across four, one, and one domain, respectively. The majority of MCC CPGs are lacking in specifying stakeholder involvement, applicability, and rigor of development. The two high quality CPGs are from the Alberta Health Services (AHS) and the collaboration between the European Dermatology Forum, the European Association of Dermato-Oncology, and the European Organization of Research and Treatment of Cancer (EDF/EADO/EORTC). The EDF/EADO/EORTC CPG had the highest overall score with no significant deficiencies across any domain. An important limitation is that the AGREE II instrument is not designed to evaluate the validity of each CPG’s recommendations; conclusions therefore can only be drawn about each CPG’s developmental quality. Future MCC CPGs may benefit from garnering public perspectives, inviting external expert review, and considering available resources and implementation barriers during their developmental stages.

Disentangling the relationships of body mass index and circulating sex hormone concentrations in mammographic density using Mendelian randomization.

Mammographic density phenotypes, adjusted for age and body mass index (BMI), are strong predictors of breast cancer risk. BMI is associated with mammographic density measures, but the role of circulating sex hormone concentrations is less clear. We investigated the relationship between BMI, circulating sex hormone concentrations, and mammographic density phenotypes using Mendelian randomization (MR). We applied two-sample MR approaches to assess the association between genetically predicted circulating concentrations of sex hormones [estradiol, testosterone, sex hormone-binding globulin (SHBG)], BMI, and mammographic density phenotypes (dense and non-dense area). We created instrumental variables from large European ancestry-based genome-wide association studies and applied estimates to mammographic density phenotypes in up to 14,000 women of European ancestry. We performed analyses overall and by menopausal status. Genetically predicted BMI was positively associated with non-dense area (IVW: β = 1.79; 95% CI = 1.58, 2.00; p = 9.57 × 10-63) and inversely associated with dense area (IVW: β = - 0.37; 95% CI = - 0.51,- 0.23; p = 4.7 × 10-7). We observed weak evidence for an association of circulating sex hormone concentrations with mammographic density phenotypes, specifically inverse associations between genetically predicted testosterone concentration and dense area (β = - 0.22; 95% CI = - 0.38, - 0.053; p = 0.009) and between genetically predicted estradiol concentration and non-dense area (β =  - 3.32; 95% CI = - 5.83, - 0.82; p = 0.009), although results were not consistent across a range of MR approaches. Our findings support a positive causal association between BMI and mammographic non-dense area and an inverse association between BMI and dense area. Evidence was weaker and inconsistent for a causal effect of circulating sex hormone concentrations on mammographic density phenotypes. Based on our findings, associations between circulating sex hormone concentrations and mammographic density phenotypes are weak at best.

Medical students’ knowledge on palliative care – a survey of teaching in Finland

Background Most studies on palliative medicine (PM) undergraduate education have focused on contents and organizational issues but not the outcome. Students’ learning outcomes should be studied to improve teaching in medical schools. Methods A questionnaire about perceived PM education and attitudes on palliative care (PC) was sent to 543 last year students in all five Finnish medical schools in 2018–2019. In total, 175 (32 %) responses were received from four universities. The students evaluated both the quantity and quality of their PM teaching, implementation of European Association for Palliative Care (EAPC) guidelines and their satisfaction to the training. There were two palliative case scenarios, and the students were asked to find the best treatment option. Results In the Finnish universities, PM education was available mainly integrated with oncology, geriatrics, and general medicine. A total of two universities also offered a specific PM course. In average, 50–70% of the EAPC curriculum was covered by lectures, small-group teaching, seminars, and bedside teaching with significant differences between faculties. Only 30–60 % of students were satisfied with the education received. The highest rankings were given in the universities with a special PM course. Conclusions In Finland, the coverage of EAPC curriculum is satisfactory, but the PM education is mainly given integrated with other specialties. The dedicated course on PM was associated with increased perceived knowledge and satisfaction of PM education. However, PM training was not associated with students’ attitudes on PC.

Detection and Real-Time Surgical Assessment of Colorectal Liver Metastases Using Near-Infrared Fluorescence Imaging during Laparoscopic and Robotic-Assisted Resections.

The European Association of Endoscopic Surgery (EAES) recommends, with strong evidence, the use of indocyanine green (ICG) fluorescence imaging combined with intraoperative ultrasound (IOUS) to improve identification of superficial liver tumors. This study reports the use of ICG for the detection of colorectal liver metastases (CRLMs) during minimally invasive liver resection. A single-center consecutive series of minimally invasive (laparoscopic and robotic) hepatic resections for CRLMs was prospectively evaluated (April 2019 and October 2023). A total of 25 patients were enrolled-11 undergoing laparoscopic and 14 undergoing robotic procedures. The median age was 65 (range 50-85) years. Fifty CRLMs were detected: twenty superficial, eight exophytic, seven shallow (<8 mm from the hepatic surface), and fifteen deep (>10 mm from the hepatic surface) lesions. The detection rates of CRLMs through preoperative imaging, laparoscopic ultrasound (LUS), ICG fluorescence, and combined modalities (ICG and LUS) were 88%, 90%, 68%, and 100%, respectively. ICG fluorescence staining allowed us to detect five small additional superficial lesions (not identified with other preoperative/intraoperative techniques). However, two lesions were false positive fluorescence accumulations. All rim fluorescence pattern lesions were CRLMs. ICG fluorescence was used as a real-time guide to assess surgical margins during parenchymal-sparing liver resections. All patients with integrity of the fluorescent rim around the CRLM displayed a radical resection during histopathological analysis. Four patients (8%) with a protruding rim or residual rim patterns had positive resection margins. ICG fluorescence imaging can be integrated with other conventional intraoperative imaging techniques to optimize intraoperative staging. Rim fluorescence proved to be a valid indicator of the resection margins: by removing the entire fluorescent area, a tumor-negative resection (R0) is achieved.

Skin cancers are the most frequent cancers in fair-skinned populations, but we can prevent them.

Cancers of the skin are the most commonly occurring cancers in humans. In fair-skinned populations, up to 95% of keratinocyte skin cancers and 70–95% of cutaneous melanomas are caused by ultraviolet radiation and are thus theoretically preventable. Currently, however, there is no comprehensive global advice on practical steps to be taken to reduce the toll of skin cancer. To address this gap, an expert working group comprising clinicians and researchers from Africa, America, Asia, Australia, and Europe, together with learned societies (European Association of Dermato-Oncology, Euromelanoma, Euroskin, European Union of Medical Specialists, and the Melanoma World Society) reviewed the extant evidence and issued the following evidence-based recommendations for photoprotection as a strategy to prevent skin cancer. Fair skinned people, especially children, should minimise their exposure to ultraviolet radiation, and are advised to use protective measures when the UV index is forecast to reach 3 or higher. Protective measures include a combination of seeking shade, physical protection (e.g. clothing, hat, sunglasses), and applying broad-spectrum, SPF 30 + sunscreens to uncovered skin. Intentional exposure to solar ultraviolet radiation for the purpose of sunbathing and tanning is considered an unhealthy behaviour and should be avoided. Similarly, use of solaria and other artificial sources of ultraviolet radiation to encourage tanning should be strongly discouraged, through regulation if necessary. Primary prevention of skin cancer has a positive return on investment. We encourage policymakers to communicate these messages to the general public and promote their wider implementation.
