Health data sharing attitudes towards primary and secondary use of data: a systematic review

Background

To receive the best care, people share their health data (HD) with their health practitioners (known as sharing HD for primary purposes). However, during the past two decades, sharing for other (i.e., secondary) purposes has become of great importance in numerous fields, including public health, personalized medicine, research, and development. We aimed to conduct the first comprehensive overview of all studies that investigated people's HD sharing attitudes-along with associated barriers/motivators and significant influencing factors-for all data types and across both primary and secondary uses.

Methods

We searched PubMed, MEDLINE, PsycINFO, Web of Science, EMBASE, and CINAHL for relevant studies published in English between database inception and February 28, 2023, using a predefined set of keywords. Studies were included, regardless of their design, if they reported outcomes related to attitudes towards sharing HD. We extracted key data from the included studies, including the type of HD involved and findings related to: HD sharing attitudes (either in general or depending on type of data/user); barriers/motivators/benefits/concerns of the study participants; and sociodemographic and other variables that could impact HD sharing behaviour. The qualitative synthesis was conducted by dividing the studies according to the data type (resulting in five subgroups) as well as the purpose the data sharing was focused on (primary, secondary or both). The Newcastle-Ottawa Scale (NOS) was used to assess the quality of non-randomised studies. This work was registered with PROSPERO, CRD42023413822.

Findings

Of 2109 studies identified through our search, 116 were included in the qualitative synthesis, yielding a total of 228,501 participants and various types of HD represented: person-generated HD (n = 17 studies and 10,771 participants), personal HD in general (n = 69 studies and 117,054 participants), Biobank data (n = 7 studies and 27,073 participants), genomic data (n = 13 studies and 54,716 participants), and miscellaneous data (n = 10 studies and 18,887 participants). The majority of studies had a moderate level of quality (83 [71.6%] of 116 studies), but varying levels of quality were observed across the included studies. Overall, studies suggest that sharing intentions for primary purposes were observed to be high regardless of data type, and it was higher than sharing intentions for secondary purposes. Sharing for secondary purposes yielded variable findings, where both the highest and the lowest intention rates were observed in the case of studies that explored sharing biobank data (98% and 10%, respectively). Several influencing factors on sharing intentions were identified, such as the type of data recipient, data, consent. Further, concerns related to data sharing that were found to be mutual for all data types included privacy, security, and data access/control, while the perceived benefits included those related to improvements in healthcare. Findings regarding attitudes towards sharing varied significantly across sociodemographic factors and depended on data type and type of use. In most cases, these findings were derived from single studies and therefore warrant confirmations from additional studies.

Interpretation

Sharing health data is a complex issue that is influenced by various factors (the type of health data, the intended use, the data recipient, among others) and these insights could be used to overcome barriers, address people's concerns, and focus on spreading awareness about the data sharing process and benefits.

Use of oxygen-ozone therapy to improve the effectiveness of antibiotic treatment on infected arthroplasty: protocol for a superiority, open-label, multicentre, randomised, parallel trial

INTRODUCTION

Surgical site infections still remain a major public health challenge and have become an increasing universal risk, especially for the implantation of orthopaedic devices.Unfortunately, the discovery and increasingly widespread use (especially the misuse) of antibiotics have led to the rapid appearance of antibiotic-resistant strains today; more and more infections are caused by microorganisms that fail to respond to conventional treatments.Oxygen-ozone therapy has been extensively used and studied for decades across various potential medical applications and has provided consistent effects with minimal side effects.This study aims to determine the superiority of oxygen-ozone therapy in combination with oral antibiotic therapy in patients with wound infections after an orthopaedic device implantation when compared with antibiotic therapy alone.

METHODS AND ANALYSIS

This is an open-label, multicentre, randomised, parallel-group study that aims to assess the efficacy and safety of oxygen-ozone therapy in combination with oral antibiotic therapy to treat infections in patients (male or female aged ≥18 years) having undergone surgery for the implant of an orthopaedic device. Patients must have at least one (but no more than three) postoperative wounds in the site of surgery (ulcers, eschars and sores) and at least one symptom (pain, burning, redness and malodour) and at least one sign (erythema, local warmth, swelling and purulent secretion) of infection of at least moderate intensity (score ≥2) in the target lesion at the screening visit (patients with wounds without signs of localised infection or with undermining wounds will be excluded).Patients (n=186) will be recruited from five Italian hospitals and studied for 7 weeks. All will be assigned to one of the two treatment groups according to a web-based, centralised randomisation procedure and placed into either the (1) intervention: oxygen-ozone therapy 2-3 times a week for 6 weeks (for a maximum of 15 sessions) simultaneously with an appropriate oral antibiotic therapy prescribed at baseline or (2) control: oral antibiotic therapy prescribed at baseline.The primary outcome is the efficacy and superiority of the treatment (ozone and oral antibiotic therapies); secondary outcomes include the resolution of signs and symptoms, modifications in lesion size and the treatment's safety and tolerability.

ETHICS AND DISSEMINATION

This study has been reviewed and approved by the responsible Independent Ethics Committee (IEC) of COMITATO ETICO CAMPANIA NORD, located at 'Azienda Ospedaliera San Giuseppe Moscati di Avellino'.After completion of the study, the project coordinator will prepare a draft manuscript containing the final results of the study on the basis of the statistical analysis. The manuscript will be derived by the co-authors for comments, and after revision, it will be sent to a major scientific journal. Findings will be disseminated via online and print media, events and peer-reviewed journals.

Challenges facing mental health systems arising from the COVID-19 pandemic: Evidence from 14 European and North American countries

We assessed challenges that the COVID-19 pandemic presented for mental health systems and the responses to these challenges in 14 countries in Europe and North America. Experts from each country filled out a structured questionnaire with closed- and open-ended questions between January and June 2021. We conducted thematic analysis to investigate the qualitative responses to open-ended questions, and we summarized the responses to closed-ended survey items on changes in telemental health policies and regulations. Findings revealed that many countries grappled with the rising demand for mental health services against a backdrop of mental health provider shortages and challenges responding to workforce stress and burnout. All countries in our sample implemented new policies or initiatives to strengthen mental health service delivery - with more than two-thirds investing to bolster their specialized mental health care sector. There was a universal shift to telehealth to deliver a larger portion of mental health services in all 14 countries, which was facilitated by changes in national regulations and policies; 11 of the 14 participating countries relaxed regulations and 10 of 14 countries made changes to reimbursement policies to facilitate telemental health care. These findings provide a first step to assess the long-term challenges and re-organizational effect of the COVID-19 pandemic on mental health systems in Europe and North America.

Public health leadership in the COVID-19 era: how does it fit? A scoping review

The COVID-19 pandemic has put a lot of pressure on all the world's health systems and public health leaders who have often found themselves unprepared to handle an emergency of this magnitude. This study aims to bring together published evidence on the qualities required to leaders to deal with a public health issue like the COVID-19 pandemic. This scoping literature review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews checklist. A search of relevant articles was performed in the PubMed, Scopus and Web of Science databases. A total of 2499 records were screened, and 45 articles were included, from which 93 characteristics of effective leadership were extrapolated and grouped into 6 clusters. The qualities most frequently reported in the articles were human traits and emotional intelligence (46.7%) and communication skills such as transparency and reliability (48.9%). Responsiveness and preparedness (40%), management skills (33.3%) and team working (35.6%) are considered by a significant percentage of the articles as necessary for the construction of rapid and effective measures in response to the emergency. A considerable proportion of articles also highlighted the need for leaders capable of making evidence-based decisions and driving innovation (31.1%). Although identifying leaders who possess all the skills described in this study appears complex, determining the key characteristics of effective public health leadership in a crisis, such as the COVID-19 pandemic, is useful not only in selecting future leaders but also in implementing training and education programmes for the public health workforce.

National Recovery and Resilience Plan and Health: qualitative analysis on the sustainability of the interventions on healthcare

Background

Sars-CoV2 epidemic was the cause of death of more than 180,000 Italian citizens. The sever-ity of this disease showed to policymakers how easily Italian health services, and particularly hospitals, could be overwhelmed by requests and needs from patients and the general population. As a consequence of the clogging of health services, the government decided to allocate a consistent investment to the com-munity and proximity assistance with a specific section (Mission 6) of the so called "National Recovery and Resilience Plan".

Objective

The aim of this study is to analyse the economic and social impact of the Mission 6 of the National Recovery and Resilience Plan, with particular regard to the most relevant interventions (Community Homes, Community Hospitals, Integrated Home Care), in order to understand its future sustainability.

Material and methods

A qualitative research methodology was chosen. Documents containing all the relevant information regarding the sustainability of the plan (called in short "Sustainability Plan") were taken into consideration. In case of missing data regarding the potential costs or expenditure of the afore-mentioned structures, estimates will be made reviewing literature for similar healthcare services, already implemented and active in Italy. Direct content analysis was chosen as the methodology for data analysis and final reporting of results.

Results

The National Recovery and Resilience Plan states that it will create savings of up to €1.18 bil-lion thanks to the re-organization of healthcare facilities, the reduction of hospitalizations, the reduction of inappropriate access to the emergency room, and the containment of pharmaceutical expenditure. This amount will be used to cover the salaries for the healthcare professionals employed in the newly planned healthcare structures. The analysis of this study has taken into account the number of healthcare profes-sionals that will be needed to operationalize the new facilities, as described in the plan and compared them with the reference salaries for each category (doctors, nurses, other healthcare workers). The annual cost for healthcare professionals has been stratified for each structure, with the following results: € 540 million for the personnel of the Community Hospitals ("Ospedali di Comunità"); € 1.1 billion for the personnel of Integrated Home Care Assistance ("Assistenza Domiciliare Integrata"); and € 540 million for the personnel of Community Homes ("Case della Comunità").

Discussion

The expected € 1.18 billion expenditure is implausible to be sufficient to cover the cost for salaries of all the healthcare professionals needed, which is expected to be around € 2 billion. The National Agency for the Regional Healthcare Services ("Agenzia nazionale per i servizi sanitari regionali") calculated that in Emilia-Romagna (the only region in Italy to have already implemented a healthcare structure based on the one described in the National Recovery and Resilience Plan), the activation of Community Hospitals and Community Homes reduced the rate of inappropriate access to emergency rooms by 26% (while in the National Recovery and Resilience Plan expectation is a reduction of at least by 90% for "white codes", the identified code for stable and not urgent patients). Moreover, the hypothesis for the daily cost of stay in the Community Hospital is roughly € 106, while the average current cost in the active Community Hospitals in Italy is € 132 (much higher than the National Recovery and Resilience Plan estimate).

Conclusion

The underlying principle of the National Recovery and Resilience Plan is highly valuable since it strives to enhance the quality and the quantity of the healthcare services in the country that are too often left out of national investments and programs. Nevertheless, the National Recovery and Resilience Plan has critical issues due to the superficial prevision of cost. The success of the reform appears to be established by decision makers and by their long-term prospective, oriented to overcome the resistance to change.

Effects of the Italian Law on Patient Safety and Health Professional Responsibilities Five Years after Its Approval by the Italian Parliament

The application of the Italian law No. 24/2017, which focused on patient safety and medical liability, in the Italian National Health Service has been evaluated by a survey conducted five years after the promulgation of the law. The law required the establishment of healthcare risk management and patient safety centers in all Italian regions and the appointment of a Clinical Risk Manager (CRM) in all Italian public and private healthcare facilities. This study demonstrates that five years after the approval of the law, it has not yet been fully implemented. The survey revealed a lack of adequate permanent staff in all the Regional Centers, with two employees on average per Center. Few meetings were held with the Regional Healthcare System decision-makers with less than four meetings per year. This reduces the capacity to carry out functions. In addition, the role of the CRMs is weak in most healthcare facilities. More than 20% of CRMs have other roles in the same organization. Some important tasks have reduced application, e.g., assessment of the inappropriateness risk (reported only by 35.3% of CRM) and use of patient safety indicators for monitoring hospitals (20.6% of CRM). The function of the Regional Centers during the COVID-19 pandemic was limited despite the CRMs being very committed. The CRMs units undertake limited research and have reduced collaboration with citizen associations. Despite most of the CRMs believing that the law has had an important role in improving patient safety, 70% of them identified clinicians' resistance to change and lack of funding dedicated to implementing the law as the main barriers to the management of risk.

Strengthening and promoting digital health practice: results from a Global Digital Health Partnership's survey

Background and objective

The capacity to promote and disseminate the best evidence-based practices in terms of digital health innovations and technologies represents an important goal for countries and governments. To support the digital health maturity across countries the Global Digital Health Partnership (GDHP) was established in 2019. The mission of the GDHP is to facilitate global collaboration and knowledge-sharing in the design of digital health services, through the administration of surveys and white papers.

Objective

The scope of this study is to critically analyze and discuss results from the Evidence and Evaluation GDHP Work Stream's survey, understand how governments and countries intend to address main obstacles to the digital health implementation, identify their strategies for a communication of effective digital health services, and promote the sharing of international based best practices on digital health.

Methods

This survey followed a cross-sectional study approach. A multiple-choice questionnaire was designed to gather data. Choices were extracted from research publications retrieved through a rapid review.

Results

Out of 29 countries receiving the survey, 10 returned it. On a scale from 1 to 5, eHealth systems/platforms (mean = 3.56) were indicated as the most important tool for centralized infrastructure to collect information on digital health, while primary care (mean = 4.0) represented the most voted item for healthcare services to collect information on digital health. Seven Countries out of 10 identified lack of organization, skepticism of clinicians, and accessibility of the population as a barriers to adopt digital health implementation, resulting to be the most voted items. Finally, the most endorsed priorities in digital health for Countries were the adoption of data-driven approaches (6 Countries), and telehealth (5 Countries).

Conclusion

This survey highlighted the main tools and obstacles for countries to promote the implementation of evidence-based digital health innovations. Identifying strategies that would communicate the value of health care information technology to healthcare professionals are particularly imperative. Effective communication programs for clinicians and the general population in addition to improved digital health literacy (both for clinicians and citizens) will be the key for the real implementation of future digital health technologies.

Italy: Health System Review

This analysis of the Italian health system reviews recent developments in organization and governance, health financing, health care provision, health reforms and health system performance. Italy has a regionalized National Health Service (SSN) that provides universal coverage largely free of charge at the point of delivery, though certain services and goods require a co-payment. Life expectancy in Italy is historically among the highest in the EU. However, regional differences in health indicators are marked, as well as in per capita spending, distribution of health professionals and in the quality of health services. Overall, Italy's health spending per capita is lower than the EU average and is among the lowest in western European countries. Private spending has increased in recent years, although this trend was halted in 2020 during the coronavirus disease 2019 (COVID-19) pandemic. A key focus of health policies in recent decades was to promote a shift away from unnecessary inpatient care, with a considerable reduction of acute hospital beds and stagnating overall growth in health personnel. However, this was not counterbalanced by a sufficient strengthening of community services in order to cope with the ageing population's needs and related chronic conditions burden. This had important repercussions during the COVID-19 emergency, as the health system felt the impact of previous reductions in hospital beds and capacity and underinvestment in community-based care. Reorganizing hospital and community care will require a strong alignment between central and regional authorities. The COVID-19 crisis also highlighted several issues pre-dating the pandemic that need to be addressed to improve the sustainability and resilience of the SSN. The main outstanding challenges for the health system are linked to addressing historic underinvestment in the health workforce, modernizing outdated infrastructure and equipment, and enhancing information infrastructure. Italy's National Recovery and Resilience Plan, underwritten by the Next Generation EU budget to assist with economic recovery from the COVID-19 pandemic, contains specific health sector priorities, such as strengthening the country's primary and community care, boosting capital investment and funding the digitalization of the health care system.

Ukrainian refugee crisis: the experience of the Roman Local Health Authority “ASL Roma 1”

Problem

On February 24th, 2022, Ukraine was invaded by Russian forces, forcing many Ukrainians to flee from their homes as refugees. More than 55,000 Ukrainians have since arrived on Italian territory. In response to the humanitarian crisis, the Roman Local Health Authority “ASL Roma 1” provided socio-sanitary assistance through first reception centers to more than 7700 refugees, prioritizing people with high social vulnerability. Ukraine’s vaccine hesitancy and different epidemiological landscape represented a major hurdle to be overcome.

Practice

ASL Roma 1’s practice served to ensure infectious diseases prevention and control, as well as continuity of care for non-communicable diseases and mental health issues. It consisted of repurposing resources, such as COVID-19 Hubs and their personnel, stipulating Public-Private Partnerships and collaborations with the local Ukrainian community, massive training, creating a centralized multidisciplinary team (with Ukrainian members) and a dedicated database/IT system.

Results

ASL Roma 1 empowered local Ukrainian communities by providing equipment, medical and administrative staff and socio-sanitary assistance. Ukrainian volunteers helped bridge the cultural gap for essential service provision, such as COVID-19 screening, enrolment in the NHS, health and social orientation, vaccinations and a tailored care pathway. Thus, more than 7700 refugees were assisted, with 1830 COVID-19 vaccinations administered and 170 in critical conditions promptly receiving specialized care.

Lessons

The multidisciplinary and cross-cultural interaction between doctors, nurses, cultural mediators, social workers, and other key actors was essential in ensuring a holistic care pathway. Services catered to Ukrainian refugees need complete integration between primary and centralized care. Flexibility and resilience are fundamental to foster an ecosystem of innovation and optimization of healthcare provision on all levels, from local to supranational.

Key messages

• The multidisciplinary and cross-cultural interaction between all medical and non-medical key actors is essential in ensuring a holistic care pathway and complete social integration of asylum seekers.

• Health system flexibility, resilience and an ecosystem of innovation and optimization of healthcare provision on all levels are fundamental components of preparedness for future refugee crises.

Leadership in public health crisis: a review to summarize lessons learned from COVID-19 pandemic

Background

During the COVID-19 pandemic, several public health challenges were faced, requiring worldwide leaders able to direct, guide, and establish appropriate strategies. The aim of this review was to summarize evidence on public health leadership during the COVID-19 era.

Methods

The systematic literature review was conducted according to the PRISMA 2020 checklist. A search of relevant articles was performed in the PubMed, Scopus, and Web of Science databases. Eligible articles were any type of publication, published between 2020 and 2022, that outlined one or more characteristics of effective public health leadership during the COVID-19 pandemic We excluded all articles that did not explicitly address the COVID-19 pandemic or had a different setting.

Results

A total of 2499 records were screened, and 45 articles were included. We identified 93 characteristics, clustered in six groups, that were reported as fundamental to be an effective leader in public health crises worldwide. Emotional intelligence and human traits (reported by 46.67% of the articles) were considered essential to build trust in the population and ensure cooperation with working groups. Communication skills (47%) are considered necessary to enable people to understand and accept measures. A supportive, multidisciplinary team and accountability mechanisms (33,33%) were highlighted as central elements, especially in the international field, to ensure reliability and consistency in action. Management skills (35,56%), adaptability (44,44%), and evidence-based approach (33,33%) were reported as key capabilities to ensure a prompt and rapid response to the challenges created by the pandemic.

Conclusions

The identification of the attributes of an effective public health leader conducted in this study is useful in choosing the key personalities who must lead public health today and in the training of tomorrow's European and worldwide leaders to be ready to face future threats.

Key messages

• Effective public health leaders in crisis are empathetic and trustworthy people, who have developed management and communication skills, and are able to make timely and evidence-based decisions.

• In order to create leaders capable of facing future threats, more emphasis in the training of public health workforce on soft skills and management competencies should be recommended.

Approaches to priority identification in digital health in ten countries of the Global Digital Health Partnership

BACKGROUND

To promote shared digital health best practices in a global context, as agreed within the Global Digital Health Partnership (GDHP), one of the most important topics to evaluate is the ability to detect what participating countries believe to be priorities suitable to improve their healthcare systems. No previously published scientific papers investigated these aspects as a cross-country comparison.

OBJECTIVE

The aim of this paper is to present results concerning the priorities identification section of the Evidence and Evaluation survey addressed to GDHP members in 2021, comparing countries' initiatives and perspectives for the future of digital health based on internationally agreed developments.

METHODS

This survey followed a cross-sectional study approach. An online survey was addressed to the stakeholders of 29 major countries.

RESULTS

Ten out of 29 countries answered the survey. The mean global score of 3.54 out of 5, calculated on the whole data set, demonstrates how the global attention to a digital evolution in health is shared by most of the evaluated countries.

CONCLUSION

The resulting insights on the differences between digital health priority identification among different GDHP countries serves as a starting point to coordinate further progress on digital health worldwide and foster evidence-based collaboration.

Scoping review of the current landscape of AI-based applications in clinical trials

Background

Clinical trials are essential for bringing new drugs, technologies and procedures to the market and clinical practice. Considering the design and the four-phase development, only 10% of them complete the entire process, partly due to the increasing costs and complexity of clinical trials. This low completion rate has a huge negative impact in terms of population health, quality of care and health economics and sustainability. Automating some of the process' tasks with artificial intelligence (AI) tools could optimize some of the most burdensome ones, like patient selection, matching and enrollment; better patient selection could also reduce harmful treatment side effects. Although the pharmaceutical industry is embracing artificial AI tools, there is little evidence in the literature of their application in clinical trials.

Methods

To address this issue, we performed a scoping review. Following the PRISMA-ScR guidelines, we performed a search on PubMed for articles on the implementation of AI in the development of clinical trials.

Results

The search yielded 772 articles, of which 15 were included. The articles were published between 2019 and 2022 and the results were presented descriptively. About half of the studies addressed the topic of patient recruitment; 12 articles reported specific examples of AI applications; five studies presented a quantitative estimate of the effectiveness of these tools.

Conclusion

All studies present encouraging results on the implementation of AI-based applications to the development of clinical trials. AI-based applications have a lot of potential, but more studies are needed to validate these tools and facilitate their adoption.

The cost-effectiveness of digital health interventions: A systematic review of the literature

Background

Digital health interventions have significant potential to improve safety, efficacy, and quality of care, reducing waste in healthcare costs. Despite these premises, the evidence regarding cost and effectiveness of digital tools in health is scarce and limited.

Objectives

The aim of this systematic review is to summarize the evidence on the cost-effectiveness of digital health interventions and to assess whether the studies meet the established quality criteria.

Methods

We queried PubMed, Scopus and Web of Science databases for articles in English published from January 1, 2016 to December 31, 2020 that performed economic evaluations of digital health technologies. The methodological rigorousness of studies was assessed with the Consolidated Health Economic Evaluation Reporting Standards (CHEERS). The review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) 2009 checklist.

Results

Search identified 1,476 results, 552 of which were selected for abstract and 35 were included in this review. The studies were heterogeneous by country (mostly conducted in upper and upper-middle income countries), type of eHealth intervention, method of implementation, and reporting perspectives. The qualitative analysis identified the economic and effectiveness evaluation of six different types of interventions: (1) seventeen studies on new video-monitoring service systems; (2) five studies on text messaging interventions; (3) five studies on web platforms and digital health portals; (4) two studies on telephone support; (5) three studies on new mobile phone-based systems and applications; and (6) three studies on digital technologies and innovations.

Conclusion

Findings on cost-effectiveness of digital interventions showed a growing body of evidence and suggested a generally favorable effect in terms of costs and health outcomes. However, due to the heterogeneity across study methods, the comparison between interventions still remains difficult. Further research based on a standardized approach is needed in order to methodically analyze incremental cost-effectiveness ratios, costs, and health benefits.

Social media and attitudes towards a COVID-19 vaccination: A systematic review of the literature

BACKGROUND

Vaccine hesitancy continues to limit global efforts in combatting the COVID-19 pandemic. Emerging research demonstrates the role of social media in disseminating information and potentially influencing people's attitudes towards public health campaigns. This systematic review sought to synthesize the current evidence regarding the potential role of social media in shaping COVID-19 vaccination attitudes, and to explore its potential for shaping public health interventions to address the issue of vaccine hesitancy.

METHODS

We performed a systematic review of the studies published from inception to 13 of March2022 by searching PubMed, Web of Science, Embase, PsychNET, Scopus, CINAHL, and MEDLINE. Studies that reported outcomes related to coronavirus disease 2019 (COVID-19) vaccine (attitudes, opinion, etc.) gathered from the social media platforms, and those analyzing the relationship between social media use and COVID-19 hesitancy/acceptance were included. Studies that reported no outcome of interest or analyzed data from sources other than social media (websites, newspapers, etc.) will be excluded. The Newcastle Ottawa Scale (NOS) was used to assess the quality of all cross-sectional studies included in this review. This study is registered with PROSPERO (CRD42021283219).

FINDINGS

Of the 2539 records identified, a total of 156 articles fully met the inclusion criteria. Overall, the quality of the cross-sectional studies was moderate - 2 studies received 10 stars, 5 studies received 9 stars, 9 studies were evaluated with 8, 12 studies with 7,16 studies with 6, 11 studies with 5, and 6 studies with 4 stars. The included studies were categorized into four categories. Cross-sectional studies reporting the association between reliance on social media and vaccine intentions mainly observed a negative relationship. Studies that performed thematic analyses of extracted social media data, mainly observed a domination of vaccine hesitant topics. Studies that explored the degree of polarization of specific social media contents related to COVID-19 vaccines observed a similar degree of content for both positive and negative tone posted on different social media platforms. Finally, studies that explored the fluctuations of vaccination attitudes/opinions gathered from social media identified specific events as significant cofactors that affect and shape vaccination intentions of individuals.

INTERPRETATION

This thorough examination of the various roles social media can play in disseminating information to the public, as well as how individuals behave on social media in the context of public health events, articulates the potential of social media as a platform of public health intervention to address vaccine hesitancy.

A Process Mining Pipeline to Characterize COVID-19 Patients' Trajectories and Identify Relevant Temporal Phenotypes From EHR Data

The impact of the COVID-19 pandemic involved the disruption of the processes of care and the need for immediately effective re-organizational procedures. In the context of digital health, it is of paramount importance to determine how a specific patients' population reflects into the healthcare dynamics of the hospital, to investigate how patients' sub-group/strata respond to the different care processes, in order to generate novel hypotheses regarding the most effective healthcare strategies. We present an analysis pipeline based on the heterogeneous collected data aimed at identifying the most frequent healthcare processes patterns, jointly analyzing them with demographic and physiological disease trajectories, and stratify the observed cohort on the basis of the mined patterns. This is a process-oriented pipeline which integrates process mining algorithms, and trajectory mining by topological data analyses and pseudo time approaches. Data was collected for 1,179 COVID-19 positive patients, hospitalized at the Italian Hospital “Istituti Clinici Salvatore Maugeri” in Lombardy, integrating different sources including text admission letters, EHR and hospital infrastructure data. We identified five temporal phenotypes, from laboratory values trajectories, which are characterized by statistically significant different death risk estimates. The process mining algorithms allowed splitting the data in sub-cohorts as function of the pandemic waves and of the temporal trajectories showing statistically significant differences in terms of events characteristics.

Governance of academic medical centres in changing healthcare systems: An international comparison

We provide an explorative and international comparison of the governance models of academic medical centres (AMCs). These centres face significant challenges, including disruptive external pressures and enduring financial conflicts pertaining to patient treatment, research and education. Therefore, we covered 10 European countries (Cyprus, Czechia, Denmark, Germany, Italy, Latvia, the Netherlands, Norway, Poland and Spain) and one associated state (Israel) in our analysis. In addition, we developed an expert questionnaire to collect data on the governance of AMCs in these 11 countries. Our results revealed no standardised definition of AMCs, with countries combining patient care, education/teaching and research differently. However, the ownership of such institutions is significantly homogeneous and is limited to public or private, nonprofit ownership. Furthermore, significant differences are associated with the (functional) integration level between the hospital and medical school. Therefore, most experts believe that the governance of AMCs will evolve into a more functionally integrated model of patient care, research and education.

Is blockchain the breakthrough we are looking for to facilitate genomic data sharing? The European Union perspective

The recent progress of genomics research is providing unprecedented insight into human genetic variance, susceptibility to disease and risk stratification. Current trends predict that a massive amount of genomic data will be produced in the upcoming years which, when coupled with the fast-paced development of the field, will create new social, ethical, and legal challenges. In the complex legislative environment of the European Union, genomic data sharing policies will have to weigh the benefits of scientific discovery against the ethical risks posed by the act of sharing sensitive data. In this complex, interconnected environment, blockchain provides a unique and novel solution to accountability, traceability, and transparency issues regarding genomic data sharing. Implementing a distributed ledger technology-based database could empower both patients and citizens to responsibly use genomic data pertaining to them because it allows for a higher degree of control over the recipients of their data and their uses. The blockchain technology will engage both data owners and policymakers to address the multiple issues of genomic data sharing and allow us to redefine the way we look at genomics.

Digital health technologies: a systematic review of their cost-effectiveness

Background

Digital health interventions have a potential to improve safety, efficacy and quality of care, reducing waste in healthcare costs. Despite premises, the evidence regarding cost and effectiveness of digital tools in health is scarce and limited.

Objectives: The aim of this systematic review is to summarize the evidence on cost-effectiveness of digital health interventions and to assess whether the studies meet the established quality criteria.

Methods

We queried PubMed, Scopus and Web of Science databases for articles in English published from 1 January 2016 to 31 December 2020 that performed economic evaluations of digital health technologies. The methodological rigorousness of studies was assessed with a well-established checklist (CHEERS). The incremental cost-effectiveness ratio (ICER)was calculated when the reviewed study reported related data but did not express the ICER.

Results

Searches identified 1476 results, 552 of which were selected for abstract and 35 were included in this review. The studies were heterogeneous by country, type of eHealth intervention, method of implementation, and reporting perspectives. The qualitative analysis identified the economic and effectiveness evaluation of seven different types of interventions: fourteen studies on a new telemedicine service; five on telecounseling; five on teletherapy; two on telemonitoring; five on new mobile applications; two on m-health programs; one on digital platforms and one on electronic health records.

Conclusions

Findings on cost-effectiveness of digital interventions showed a growing body of evidence and suggested a generally favorable effect in terms of costs and health outcomes. However, due to the heterogeneity across study methods, the comparison between interventions still remains difficult. Further research based on a standardized approach is needed in order to methodically analyze incremental cost-effectiveness ratios, costs, and health benefits.

Key messages

Digital interventions suggested a favorable effect in terms of costs and health outcomes. Digital health interventions have a potential to improve safety, efficacy and quality of care.

How the population worldwide is reacting to the COVID-19 vaccines: a systematic review on hesitancy

Background

High rates of vaccination are worldwide required to establish a herd immunity stopping the current COVID-19 pandemic evolution. Vaccine hesitancy is a major barrier in achieving herd immunity across different populations. This study sought to conduct a systematic review of the current literature regarding attitudes and hesitancy to receiving COVID-19 vaccination worldwide.

Methods

A systematic literature search was performed in accordance with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Multiple databases were searched, namely PubMed and Web of Science, on February 24th, 2021 using a set of developed keywords. Inclusion criteria included the study to be 1) conducted in English; 2) investigated attitudes, hesitancy, and/or barriers to COVID-19 vaccine acceptability among a given population; 3) utilized validated measurements techniques; 4) have the full text paper available and 5) be peer-reviewed prior to final publication. The Newcastle Ottawa (NOS) scale for cross sectional studies was used to assess the quality of the studies.

Results

73 studies were included in qualitative synthesis. Overall, vaccine acceptance rates ranged from 23.6% in Kuwait to 94.3% in Malaysia and Nepal. A variety of different factors contributed to increased hesitancy, some of which included having negative perception of vaccine efficacy, safety, convenience and price. Some of the consistent socio-demographic groups that were identified to be associated with increased hesitancy included: women, younger participants, less educated, with lower income, with no insurance, living in the rural area and self-identified as a racial/ethnic minority.

Conclusions

Vaccine hesitancy rates against COVID-19 vaccine ranged widely among across different populations. Identifying the factors that interplay and result in high hesitancy rates among a population can allow formulating a directed intervention to increase their vaccination uptake rates.

Key messages

It is necessary to understand the factors that contribute to the COVID-19 vaccine hesitancy. It is important to inform policy-makers and formulate direct intervention measures that will successfully handle the pandemic.

Governance and organization of Academic Medical Centers – a comparative analysis of 11 countries

Background

Academic Medical Centers (AMCs) are organizations that link three functions: providing highly specialized medical services, teaching activities and conducting research. The aim of the study was to provide an international comparison of the governance and organization models of AMCs. The analysis covered 10 European countries (Cyprus, Czechia, Denmark, Germany, Italy, Latvia, Netherlands, Norway, Poland, Spain) and Israel.

Methods

The study has an explorative and descriptive character. The methods involved: (1) the creation of a conceptual framework; (2) the development of a dedicated questionnaire; (3) data collection and analysis. The data was collected based on purposive sampling. There were 26 respondents from 11 countries.

Results

There is no standardized definition of AMCs across countries. Different types of hospital providers do link patientcare, teaching and research. Depending on the country and particular institution, the balance between these three functions, as well as the scope might vary a lot. The majority of the participating countries face either public or not-for-profit ownership for AMCs and medical faculties. However, the relationship between hospital and faculty varies substantially. Main internal governance challenges focus on lack of responsiveness to change and financial conflicts between the three core tasks. External challenges relate to financial sustainability and workforce shortages. Most respondents believe that in the nearby future the governance of AMCs will evolve to a more functionally integrated model of the three functions.

Conclusions

The study fills the gap in the literature on organization and governance of European AMCs. Although, there are substantial differences in the models of governance across countries, many challenges are highly similar. This raises important questions for future research (e.g. focusing solely on one function) as well as policy (the potential for cross-national learning).

Key messages

There is no standardized definition of AMCs across countries and different types of organizations are used to link the three functions of providing patientcare, teaching activities and research. Despite the organizational and legal differences, AMCs in different countries face similar challenges (nimbleness and financial conflicts between the three functions; health workforce shortages).

Attitudes, acceptance and hesitancy among the general population worldwide to receive the COVID-19 vaccines and their contributing factors: A systematic review

BACKGROUND

High rates of vaccination worldwide are required to establish a herd immunity and stop the current COVID-19 pandemic evolution. Vaccine hesitancy is a major barrier in achieving herd immunity across different populations. This study sought to conduct a systematic review of the current literature regarding attitudes and hesitancy to receiving COVID-19 vaccination worldwide.

METHODS

A systematic literature search of PubMed and Web of Science was performed on July 5th, 2021, using developed keywords. Inclusion criteria required the study to (1) be conducted in English; (2) investigate attitudes, hesitancy, and/or barriers to COVID-19 vaccine acceptability among a given population; (3) utilize validated measurement techniques; (4) have the full text paper available and be peer-reviewed prior to final publication.

FINDINGS

Following PRISMA guidelines, 209 studies were included. The Newcastle Ottawa (NOS) scale for cross-sectional studies was used to assess the quality of the studies.Overall, vaccine acceptance rates ranged considerably between countries and between different time points, with Arabian countries showing the highest hesitancy rates compared with other parts of the world.

INTERPRETATION

A variety of different factors contributed to increased hesitancy, including having negative perception of vaccine efficacy, safety, convenience, and price. Some of the consistent socio-demographic groups that were identified to be associated with increased hesitancy included: women, younger participants, and people who were less educated, had lower income, had no insurance, living in a rural area, and self-identified as a racial/ethnic minority.

Developing a Data-Driven Approach in Order to Improve the Safety and Quality of Patient Care

Objective: To improve the safety and quality of patient care in hospitals by shaping clinical pathways throughout the patient journey.

Study Setting: A risk model designed for healthcare organizations in the context of the challenges arising from comorbidity and other treatment-related complexities.

Study Design: The core of the model is the patient and his intra-hospital journey, which is analyzed using a data-driven approach. The structure of a predictive model to support organizational and clinical decision-making activities is explained. Data relating to each step of the intra-hospital journey (from hospital admission to discharge) are extracted from clinical records.

Principal Findings: The proposed approach is feasible and can be used effectively to improve safety and quality. It enables the evaluation of clinical risks at each step of the patient journey.

Conclusion: Based on data from real cases, the model can record and calculate, over time, variables and behaviors that affect the safety and quality of healthcare organizations. This provides a greater understanding of healthcare processes and their complexity which can, in turn, advance research relating to clinical pathways and improve strategies adopted by organizations.

Comparison of Deaths Rates for COVID-19 across Europe During the First Wave of the COVID-19 Pandemic

Background: Europe overall suffered greatly in the early stages of the COVID-19 pandemic but the impact of different countries varied. Italy was in the forefront, but there too there were differences, with the Lombardy region the epicentre of the pandemic. Methods: We report Crude Mortality Rates (CMRs) from deaths reported as due to COVID-19 and, in five countries where age-specific data are available, Standardized Mortality Rates (SMRs) in the European Union and United Kingdom. Results: As of 30th August 2020, Belgium was the country with the highest cumulative CMR (86.3/100,000), but the Lombardy region reached almost double this figure (167.6/100,000), far ahead of the corresponding figure for the rest of Italy at 37.0/100,000. SMRs could be calculated for five countries (Italy, Portugal, Sweden, Germany, and Netherlands). Among them, Sweden had the highest SMR (61.6/100,000). The corresponding figures for Italy, Netherlands, Portugal and Germany were 50.2, 41.4, 15.9, and 10.1 per 100,000, respectively. Conclusion: It is clear that countries within Europe have performed very differently in their responses to the COVID-19 pandemic, but the many limitations in the available data must be addressed before a definitive assessment of the reasons for these differences can be made.

How health systems approached respiratory viral pandemics over time: a systematic review

BACKGROUND

Several healthcare systems facing respiratory viral infections outbreaks, like COVID-19, have not been prepared to manage them. Public health mitigation solutions ranging from isolation of infected or suspected cases to implementation of national lockdowns have proven their effectiveness for the outbreak's control. However, the adjustment of public health measures is crucial during transition phases to avoid new outbreaks. To address the need for designing evidence-based strategies, we performed a systematic review to identify healthcare systems interventions, experiences and recommendations that have been used to manage different respiratory viral infections outbreaks in the past.

METHODS

PubMed, Web of Science, Scopus and Cochrane were searched to retrieve eligible studies of any study design, published in English until 17 April 2020. Double-blinded screening process was conducted by titles/abstracts and subsequently eligible full texts were read and pertinent data were extracted. When applicable, quality assessment was conducted for the included articles. We performed a narrative synthesis of each implemented public health approaches.

RESULTS

We included a total of 24 articles addressing the public health approaches implemented for respiratory viral infections outbreaks for COVID-19, influenza A H1N1, MERS and severe acute respiratory syndrome . The identified approaches are ascribable to two main categories: healthcare system strategies and healthcare provider interventions. The key components of an effective response on respiratory viral outbreaks included the implementation of evidence-based contextual policies, intrahospital management actions, community healthcare facilities, non-pharmaceutical interventions, enhanced surveillance, workplace preventive measures, mental health interventions and communication plans.

CONCLUSION

The identified healthcare system strategies applied worldwide to face epidemics or pandemics are a useful knowledge base to inform decision-makers about control measures to be used in the transition phases of COVID-19 and beyond.

A data-driven methodology to discover similarities between cocaine samples

Machine learning has been used for distinct purposes in the science field but no applications on illegal drug have been done before. This study proposes a new web-based system for cocaine classification, profiling relations and comparison, that is capable of producing meaningful output based on a large amount of chemical profiling’s data. In particular, the Profiling Relations In Drug trafficking in Europe (PRIDE) system, offers several advantages to intelligence actions across Europe. Thus, it provides a standardized, broad methodology which uses machine learning algorithms to classify and compare drug profiles, highlight how similar drug samples are, and how probable it is that they share a common origin, batch, or preparation process. We evaluated the proposed algorithms using precision and recall metrics and analyzed the quality of predictions performed by the algorithms, with respect to our gold standard. In our experiments, we reached a value of 88% for F_0.5-measure, 91% for precision, and 78% for recall, confirming our main hypothesis: machine learning can learn and be applied to have an automatic classification of cocaine profiles.

Healthcare systems strategies to manage pandemics transition phases: a systematic review

Double-blinded screening process was conducted by titles/abstracts and subsequently eligible full-texts were read and pertinent data were extracted. We performed a narrative analysis of each implemented strategy.

Results

We included a total of 24 articles addressing the public health strategies implemented for respiratory viral infections outbreaks as COVID-19, influenza A H1N1, MERS and SARS. The identified strategies are ascribable to two main categories: healthcare systems management at a national level and healthcare providers strategies at a local level. The key components of the transition strategies regarded the implementation of evidence-based contextual policies, intrahospital management approaches, community healthcare facilities, non-pharmaceutical interventions, enhanced surveillance, workplace preventive measures, mental health interventions and communication plans.

Conclusions

The identified healthcare systems strategies applied worldwide to face epidemics or pandemics, are a useful knowledge base to inform decision-makers about control measures to be used in the transition phases of COVID-19 and beyond.

Key messages

Healthcare systems strategies that can be implemented to manage pandemics/epidemics transition phases are a useful knowledge base to inform policy makers about the most effective solutions to adopt.

The evidence reporting the healthcare systems management of respiratory viruses epidemics/pandemics, show the lack of a common and shared approach and more evidence-based research is needed.

Post-mortem computed tomography for forensic applications: A systematic review of gunshot deaths

The first reported application of computed tomography (CT) to the field of forensic medicine was in 1977 for the study of gunshot injuries to the head. Since then, CT scanning has shown increased uses within the field of forensic practice. In this study a systematic literature search was carried out by consulting 17 electronic scientific databases. This systematic review considers studies published to date concerning the use of post-mortem CT (PMCT) in gunshot injury cases; this review shows variability between the PMCT and autopsy examination findings. Furthermore we identify the technical differences between the selected studies, emphasizing the specific findings obtainable with PMCT, in order to support forensic research towards shared and validated practices, whose results are used as evidence in the courtroom.

Highly Predictive Genetic Markers Distinguish Drug-Type from Fiber-Type Cannabis sativa L

Genetic markers can be used in seeds and in plants to distinguish drug-type from fiber-type Cannabis Sativa L. varieties even at early stages, including pre-germination when cannabinoids are not accumulated yet. With this aim, this paper reports sequencing results for tetrahydrocannabinolic acid synthase (THCAS) and cannabidiolic acid synthase (CBDAS) genes from 21 C. sativa L. varieties. Taking into account that THCAS- and CBDAS-derived enzymes compete for the same substrate, the novelty of this work relies in the identification of markers based on both THCAS and CBDAS rather than THCAS alone. Notably, in our panel, we achieved an adequate degree of discrimination (AUC 100%) between drug-type and fiber-type cannabis samples. Our sequencing approach allowed identifying multiple genetic markers (single-nucleotide polymorphisms-SNPs-and a deletion/insertion) that effectively discriminate between the two subgroups of cannabis, namely fiber type vs. drug type. We identified four functional SNPs that are likely to induce decreased THCAS activity in the fiber-type cannabis plants. We also report the finding on a deletion in the CBDAS gene sequence that produces a truncated protein, possibly resulting in loss of function of the enzyme in the drug-type varieties. Chemical analyses for the actual concentration of cannabinoids confirmed the identification of drug-type rather than fiber-type genotypes. Genetic markers permit an early identification process for forensic applications while simplifying the procedures related to detection of therapeutic or industrial hemp.

A Fatal Mediastinitis Due to a Neck Trauma from an Undeclared Assault

History of neck trauma should be promptly investigated in patients with severe infections of the chest as mediastinitis. We present a forensic case of a death due to a mediastinitis in a patient with an undetected fracture of the superior horn of the thyroid cartilage that was exclusively revealed at autopsy examination. Histological analyses of the neck tissues showed signs of pharyngeal mucosal microperforation caused by the fracture and surrounded by an inflammatory reaction. The fracture was caused by a not declared manual strangulation attempt, happened several days before medical evaluations. We share our experience to emphasize the importance of revealing the etiologies of fatal infections of the mediastinum both for clinical and forensic purposes.

Research ethics committee auditing: the experience of a university hospital

The authors report the first Italian experience of a research ethics committee (REC) audit focused on the evaluation of the REC's compliance with standard operating procedures, requirements in insurance coverage, informed consent, protection of privacy and confidentiality, predictable risks/harms, selection of subjects, withdrawal criteria and other issues, such as advertisement details and justification of placebo. The internal audit was conducted over a two-year period (March 2009-February 2011) divided into quarters to better value the influence of the new insurance coverage regulation that came into effect in March 2010 (Ministerial Decree of 14 July, 2009) and expand the requirements to safeguard participants in clinical drug trials including other critical items as information and consent and the risks to benefits ratio. Out of a total of 639 REC's opinions and research studies, 316 were reviewed. Regarding the insurance policy requirements, Auditor/REC non-compliance occurred only in one case. The highest number of Auditor/REC non-compliance was in regard to information and consent, which should have incurred a suspended decision rather than a favorable opinion. This internal audit shows the importance and the difficulty of the review process. For this reason, specific courses for members of the research ethics committee and for those who aspire to become auditors will be provided. There may also be efforts to improve the standard operating procedures already in place.

A case of sudden infant death due to a primary cardiac sarcoma

The case reported herein concerns the unexpected death of a 3-month-old female newborn who suddenly collapsed in her mother's arms and was dead on arrival at the hospital. The clinical histories of the baby and her parents were negative for symptoms or signs of illness, even those of cardiovascular origin. Furthermore, no clinical appearance of a pathologic status was noted by pediatricians after the birth until the last emergency recovery. The autopsy excluded external and internal signs of violence but revealed a large primary cardiac tumor arising from the free wall of the left ventricle, which had totally invaded the heart causing mitral valve deformation. Histological examination showed a low-grade sarcoma that completely infiltrated the myocardial tissue. The pathogenesis of this sudden infant death was postulated as being owing to a fatal ventricular fibrillation combined with a tumor-related restrictive cardiomyopathy obstructing left ventricular filling.

Increasing delta-9-tetrahydrocannabinol (Δ-9-THC) content in herbal cannabis over time: systematic review and meta-analysis

AIM

The objective of this meta-analysis is to assess the data regarding changes in herbal cannabis potency over time (from 1970 to 2009).

METHODS

Systematic searches of 17 electronic scientific databases identified studies on this topic, within which 21 case series studies satisfied our inclusion criteria of reporting the mean tetrahydrocannabinol (THC) value per number of samples per year. No language, publication date, publication type or status restrictions were imposed. The study selection and data extraction processes were performed independently but uniformly by two authors, included screening, determination of eligibility and inclusion of the eligible studies in the systematic review, and a meta-analysis of the results on THC content in herbal cannabis samples. We considered papers and not monographic scientific publications, rejecting all studies that were not focused on the subject of this review.

RESULTS

Meta-analysis by year was performed on 21 studies containing 75 total mean THC observations from 1979 to 2009 using the random effects model. The results revealed much variability between studies. Further, there was a significant correlation between year and mean THC in herbal cannabis. The combined data indicated the correlation between year and mean THC in herbal cannabis, revealing a temporal trend of increasing potency (5% above the mean THC value in the Poisson regression analysis).

CONCLUSIONS

The results of the analysis suggest that there has been a recent and consistent increase in cannabis potency worldwide.

Foreign object ingestion in complex suicide: a case report and review of the literature

Foreign body ingestion frequently occurs accidentally in the paediatric population as well as intentionally in prisoners to achieve hospitalisation, but is relatively uncommon in forensic cases and extremely rare as a method of inducing death in complex suicide. The reasons for this infrequency are many, not least the slowness of action and the lack of effectiveness in terms of lethality, regardless of the object used. In this article, we show an unplanned complex suicide carried out by ingestion of four plastic knives before hanging. Other complex suicides involving foreign body ingestion reported in the forensic literature are reviewed.

Placental Site Trophoblastic Tumor with lung metastases as cause of death in a young patient: a case report

Placental Site Trophoblastic Tumor (PSTT) is a rare form of Gestational Trophoblastic Disease (GTD). Approximately 200 cases have been reported in the literature. This disease has unpredictable biological behavior, whereas approximately 10-15% have clinically malignant evolution. We present the case of a 21-year old woman at first pregnancy without known previous abortion at 25 weeks of amenorrhea who was admitted to the hospital for hyperemesis, hepatic problems and important weight loss registered during the last few months. Few days after the admission, the patient suddenly died before the doctors can reach a diagnosis. A forensic investigation for medical malpractice was initiated. Samples collected from uterus at the autopsy revealed large trophoblastic cells with eosinophilic cytoplasm. Deposition of fibrinoid material was noticed between trophoblastic cells. Tumor cells dissected through the myometrium and invaded into the vascular spaces. Specimens of the lungs revealed numerous small neoplastic emboli into the vessels. We show autopsy and histological findings of PSTT in a young woman, which are very rarely described in the literature and we discuss the medico-legal implications related to the great difficulties of the gynecologists who faced this rare condition in term of diagnosis and prediction of biological behavior, outlining effective therapeutic approaches.

[Phyllodes tumor of the breast]

The diagnosis of benign, malignant or borderline phylloides tumor of the breast is based on a combination of clinical and histological features but the biological behavior of this neoplasm is not often predictable: the most important indicators of malignant behavior are underscored. Only a few patients with malignant or borderline lesions develop distant metastasis; local recurrences do not appear to effect survival: as a consequence, wide resection should to be primary treatment and axillary dissection is not worthwhile.

[Penile injuries caused by masturbation with a vacuum cleaner. Description of a case and review of the literature]

The paper reports a case of penis injury which occurred while masturbating using a vacuum cleaner. This caused skin lesions and urethral lacerations which were successfully cured from both and esthetic and functional point of view. The Authors stress the extreme rarity of the case and comment on the pathological anatomy of lesions and surgical objectives on the basis of a review of the literature.

[Diagnostic reliability of echography in ureteral lithiasis]

This article takes into account the diagnostic reliability of ultrasounds (US) in the ureteral lithiasis localisation. A stone has been ultrasonographically localised in 82.3% of 119 patients, this rate rising up to 89.4% in the last 85 consecutive patients. From a clinical point of view, 104 patients presented renal signs, whereas 10 out of them showed an atypical symptomatology, which at first led to a suspicion of acute appendicitis (5), intestinal obstruction (4), acute pancreatitis (1). A stone was accidentally detected in five asymptomatic patients. In 80% of the cases, the stone was situated in the proximal or juxtavesical ureter; in 20%, in the middle or distal ureter. A particular stress is laid in the ultrasonographic follow-up, by which the stone was uncovered in 6 cases, at first considered negative at US. Eight patients had to be referred to treatment with ESWL.
