Abstract Objectives To assess awareness and knowledge of Interventional Radiology (IR) in a large population of medical students in 2019. Methods An anonymous survey was distributed electronically to 9546 medical students from first to sixth year at three European medical schools. The survey contained 14 questions, including two general questions on diagnostic radiology (DR) and artificial intelligence (AI), and 11 on IR. Responses were analyzed for all students and compared between preclinical (PCs) (first to third year) and clinical phase (Cs) (fourth to sixth year) of medical school. Of 9546 students, 1459 students (15.3%) answered the survey. Results On DR questions, 34.8% answered that AI is a threat for radiologists (PCs: 246/725 (33.9%); Cs: 248/734 (36%)) and 91.1% thought that radiology has a future (PCs: 668/725 (92.1%); Cs: 657/734 (89.5%)). On IR questions, 80.8% (1179/1459) students had already heard of IR; 75.7% (1104/1459) stated that their knowledge of IR wasn’t as good as the other specialties and 80% would like more lectures on IR. Finally, 24.2% (353/1459) indicated an interest in a career in IR with a majority of women in preclinical phase, but this trend reverses in clinical phase. Conclusions Development of new technology supporting advances in artificial intelligence will likely continue to change the landscape of radiology; however, medical students remain confident in the need for specialty-trained human physicians in the future of radiology as a clinical practice. A large majority of medical students would like more information about IR in their medical curriculum; almost a quarter of students would be interested in a career in IR.

What is the actual value of new medicines? The answer to this question is the key to rational use of new technologies in health care and for design of appropriate incentives for innovation. In this paper we present methods, data and study results for valuing new medical technologies in a life cycle perspective, relevant for development of a new approach to contract and payment for innovation that can replace present systems for pricing and reimbursement.   Focus is on value in clinical practice, and on the data needs and methods needed for the development of outcome-based payment systems that balances risks and rewards for innovation in health care. We provide an overview of studies from the Swedish context on the value of new medicines introduced in the treatment of diabetes, cancer, cardiovascular disease and rheumatoid arthritis. These studies using national health data and quality registers emphasise the importance of continuing efforts to collect relevant data for assessment of value after a medicine reaches the market and starts to be used in clinical practice. It is only when medicines are used in clinical practice that the benefits for real-world patient populations can be identified, measured and valued. Analyses of real-world data will also assist further development and tailoring of treatment strategies to optimize the value of the new technology. While an effective patent system rewards innovation for a limited period of time, many innovations may continue to provide value to society long after patent protection, and these values must be included in the assessment of value of innovation.

Prontosan® Debridement Pad (PDP; B. Braun) è un nuovo presidio disegnato per migliorare il processo di debridement meccanico. In questo lavoro riportiamo i risultati di un complesso progetto condotto al fine di sviluppare consenso tra gli esperti sul migliore modo di impiegare questa nuova tecnologia nella pratica clinica. Il progetto si è articolato in tre fasi. Nella prima è stata condotta una estesa revisione della letteratura che ha condotto ad identificare, analizzare criticamente e a riassumere in formato strutturato 27 studi clinici pertinenti. Nella seconda fase le evidenze disponibili sono state discusse in modo sistematico con un pannello di 10 esperti, i quali hanno formulato 12 raccomandazioni per l'impiego clinico del PDP. Queste raccomandazioni sono state quindi sottoposte a votazione formale attraverso il metodo GRADE. Infine, nei mesi successivi, 13 casi clinici provenienti dalla pratica clinica routinaria e trattati in accordo con le raccomandazioni stabilite sono stati raccolti e vengono qui presentati. Nel complesso, i dati disponibili in letteratura e quelli raccolti dalla pratica clinica confermano l'efficacia del PDP come strumento per il debridement meccanico, offrendo vantaggi significativi per una ottimale Wound Bed Preparation e per il controllo del dolore. Il nostro progetto può inoltre essere utile per ottimizzare l'impiego pratico di questo nuovo promettente dispositivo. Prontosan® Debridement Pad (PDP; B. Braun) is a new device designed for mechanical debridement. This paper summarizes the results of a complex initiative aimed to develop consensus among a panel of wound care experts about the optimal use of this new technology. An extensive review of the literature found 27 pertinent papers, which underwent a formal process of critical appraisal and evidence extraction by two independent methodologists. Results are displayed in an evidence report. 12 practical recommendations, concerning management of acute and chronic wounds, have been developed and approved. Main point of strength of this project is the use of a systematic approach to literature review, evidence synthesis and presentation, development and measurement of expert consensus. Moreover, expert panel provided further clinical data, through the reporting of 13 clinical cases managed according to abovementioned recommendations, with a particular focus on burns and chronic ulcers treatment, both in adult and pediatric patients. Overall, results from literature review and from clinical experience confirm that the combined system Prontosan® Solution and PDP is a promising tool useful in the critical phase of debridement in acute and chronic wounds treatment. Efficacy in debris removal and pain reduction are the main points of strength. Our project may contribute to optimize clinical use of this innovative device.

Stalk Lodging

ABSTRACTBackgroundStalk lodging (breakage of plant stems prior to harvest) is a major problem for both farmers and plant breeders. A limiting factor in addressing this problem is the lack of a reliable method for phenotyping stalk strength. Previous methods of phenotyping stalk strength induce failure patterns different from those observed in natural lodging events. This paper describes a new device for field-based phenotyping of stalk strength called “DARLING” (Device for Assessing Resistance to Lodging IN Grains). The DARLING apparatus consists of a vertical arm which is connected to a horizontal footplate by a hinge. The operator places the device next to a stalk, aligns the stalk with a force sensor, steps on the footplate, and then pushes the vertical arm forward until the stalk breaks. Force and rotation are continuously recorded during the test and these quantities are used to calculate two quantities: stalk flexural stiffness and stalk bending strength.ResultsField testing of DARLING was performed at multiple sites. Validation was based upon three factors. First, the device induces the characteristic “crease” or Brazier buckling failure patterns observed in naturally lodged stalks. Second, in agreement with prior research, flexural stiffness values attained using the DARLING apparatus are strongly correlated with bending strength measurements. Finally, a paired specimen experimental design was used to determine that the flexural data obtained with DARLING is in agreement with laboratory-based flexural testing results of the same specimens. DARLING was also deployed in the field to assess phenotyping throughput (# of stalks phenotyped per hour). Over approximately 5000 tests, the average testing rate was found to be 210 stalks/hour.ConclusionsThe DARLING apparatus provides a quantitative assessment of stalk strength in a field setting. It induces the same failure patterns observed in natural lodging events. DARLING can also be used to perform non-destructive flexural tests. This new technology has many applications, including breeding, genetic studies on stalk strength, longitudinal studies of stalk flexural stiffness, and risk assessment of lodging propensity.

It has recently been proposed to use ultraviolet (UVA) corneal collagen crosslinking as an alternative method of treating bacterial ulcerative lesions of the cornea. Ambivalent results regarding the efficacy and safety of this method of treatment limit its implementation in clinical practice so far.The purpose of this work is to analyze three clinical cases involving the use of a new device for local UVA crosslinking in the complex treatment of bacterial corneal protracted-course ulcers with the suspected development of mixed fungal infection.Material and methods. For a dynamic follow-up of patients, we used biomicroscopy with a fluorescein test, photo registration and optical coherence tomography of the anterior part of the eye. Inflammatory changes were assessed using a point scale.Results. 3–5 procedures of local UVA exposure (with instillations of 0.1% riboflavin solution) lasting 3–5 minutes each and given with an interval of 2–4 days ensured stable and fast epithelialization of the cornea and a significant increase in visual acuity in the inflammatory process outcome.Conclusion. The first results of treating bacterial corneal ulcers using a new portable device for local UVA crosslinking have shown its high therapeutic efficiency and good prospects for further use in clinical practice.

BACKGROUND A novel medical device has been developed to address an unmet need in standardising and facilitating heart rate recording during neonatal resuscitation. In a time critical emergency resuscitation, where failure can mean death of an infant, it is vital that clinicians are provided with information in a timely, precise and clear manner to capacitate appropriate decision making. This new technology provides a hands free, wireless heart rate monitoring solution that easily fits the clinical pathway and procedure for neonatal resuscutation. To understand the requirements of the interface design for this new device, a human factors approach was implemented. This combined a traditional user-centred design approach with an Applied Cognititive Task Analysis (ACTA) to understand the tasks involved, the cognitive requirements and the potential for error during a neonatal resusciation scenario. OBJECTIVE 1. To understand the cognitive requirements of clinicians for a novel medical device to facilitate neonatal resuscitation; 2. To apply a human factors approach and a traditional user-centred design approach to provide a device interface specification. METHODS Fourteen clinical staff were involved in producing the final design requirements. Two paediatric doctors supported the development of a visual representation of the activities associated with neonatal resucitation. This was used to develop a scenario based workshop. Two workshops were carried out in parallel and involved three paediatric doctors, three neonatal nurses, two advance neonatal practitioners and four midwives. Both groups came together at the end to reflect on the findings which emerged during the separate sessions. RESULTS The outputs of this study have provided a comprehensive description of information requirements during neonatal resuscitation, and enabled product developers to understand the core and preferred requirements of the user interface design for the device. The study raised three key areas for the designers to consider, which had not previously been highlighted. These related to interface layout and information priority, size and portability of the device and auditory feedback. CONCLUSIONS This study demonstrates the value of the ACTA approach to inform the development of resuscitation devices, and more generally for medical device development.

The article describes a new device for studying the act of sucking in animals. The device is designed to record the parameters that occur during the sucking act: compression forces, pushing forces, rarefaction, their amplitudes, frequencies and phases. Studies were conducted among 10 calves at different ages to determine the parameters of the sucking process. It was found that the minimum dilution in the oral cavity of a calf is observed at 2 days of age - 10.5 kPa. At 7 days of age, it amounted to 14.9 kPa, at 12 days of age - 17.3. The maximum value is observed at 28 days of age - 27.1 kPa. The compression force on the nipple also increases with age. If at 2 days of age it is 28.8 N, then at 28 days of age it is 59.1 N. When sucking, calves push the udder with an effort of 28.0 (2 days old), 31.3 (7 days) 38.9 (12 days), 46.1 (17 days), 50.1 (22 days) and 51.2 N (28 days). The frequency of sucking movements varies from 1.8 to 2.3 Hz, respectively, at 2 and 28 days of age.

The Impact

The objective of the present work was to determine some force parameters for removal of an abutment from a dental implant in a frictional system (locking taper, 1.23 degrees). Ten implants of the same length (11 mm) and different diameters were selected, along with 10 straight abutments (13 mm length) with different diameters. Abutments were attached to implants without application of force. Fixation of the implant-abutment mount (IA) (repeated 1–5 times) was performed through the impact of a body weight (compression force, tapping) left from a known height. After each group of tappings, IA mounts were coupled with a tensile strength tester. The lowest removal value was found after the first tapping of mount #2 (83 N, implant diameter 3.3 mm/4.5 mm abutment diameter), and the highest removal value happened with mount #8 after the fifth tapping (420 N, 5.0 mm/5.5 mm). The force to remove IA mounts increased with the number of tappings and with the increase in abutment mass. Three activations (tappings) of the abutment were considered necessary to yield optimal stability, demonstrated by the large increase in removal force.
