RESUMEN

INTRODUCTION: Access to medicines is one of the biggest challenges to health systems, affecting society and individuals. This study aims to explore citizens' opinions, perceptions and attitudes on the model of medicines' research and development (R&D) and price setting of medicines reimbursed by the Italian National Health Service. MATERIALS AND METHODS: We run four online focus groups, analysed through thematic analysis. INCLUSION CRITERIA: people aged 30-70 years, who had completed at least compulsory schooling (8-10 years), with no specialised knowledge about the subject. EXCLUSION CRITERIA: healthcare workers, pharmaceutical and device industry employees, researchers and medicine policy board members. We aimed to include a purposive sample of 20 participants, variable in terms of age, educational level and place of residence. RESULTS: Eleven women and six men participated. The mean age was 53 years (range: 28-73). Most (n = 15) had a university degree or attended secondary schools. Eight had a job, five were not employed, and four were retired. In general, participants supported the role of the public health service. Almost all had limited knowledge of medicines' R&D and price setting. Most asked for transparency on medicine prices and negotiation criteria. Participants considered revenues of pharmaceutical companies disproportionate and most called for containment measures of profits. Most were in favour of a stronger public intervention in R&D and prices' negotiations. Few were sceptical of the public sector's ability to play this role. DISCUSSION: Medicines' prices were discussed as a health matter. Increasing citizens' awareness of these topics is needed by providing spaces and conditions to participate in the discussion, including different perspectives and interests. PATIENT OR PUBLIC CONTRIBUTION: Members of BEUC-the European consumer organisation-proposed the project. Altroconsumo, an independent consumer organisation and OCU, a Spanish consumer organisation, participated in developing the project and the main topics to discuss. The Mario Negri Institute and Aplica cooperative-the Spanish methodological team-were involved by BEUC and their national organisations to define the methodology, organisational aspects and contents and conducted the focus groups.

RESUMEN

BACKGROUND: Patient and Public Involvement (PPI) is slowly but steadily being implemented in all phases of clinical research. As part of the European project "Building Data Rich Clinical Trials" a survey was launched to investigate the knowledge, experiences and opinions on this topic of clinicians and researchers from seven European clinical and non-clinical centers (Cancer Core Europe). METHODS: An invitation to take part in a cross-sectional web survey was sent to 199 clinicians and researchers working in the field of precision oncology. The questionnaire was developed ad hoc because no existing questionnaires met the purpose of this study. The analysis takes account of whether respondents had experience on PPI or not. RESULTS: On a total of 101 respondents, this survey reveals that 76.2% of them knew about PPI before answering the questionnaire, 54.5% had experience in the previous five years and 86.1% were interested in a training course on this topic. PPI knowledge grew together with career seniority (peak of 86.5% for established career professionals), while the group most interested in a course was the early-career professionals (100.0%). Finally, the majority of respondents stated they had no training or education on PPI (67.3% of experienced and 82.6% of not-experienced respondents). CONCLUSIONS: This survey shows that most cancer researchers knew the term PPI, even if only a little more than half of them had any relative experience. Opinions on PPI benefits, negative effects, barriers and requirements differed between the groups of PPI experienced and not-experienced respondents, showing that experience itself can influence respondents' opinions. Most of respondents reported they would prefer a training course based on practical rather than theoretical tools.

RESUMEN

BACKGROUND: Partnering with consumers in the planning, delivery and evaluation of health services is an essential component of person-centred care. There are many ways to partner with consumers to improve health services, including formal group partnerships (such as committees, boards or steering groups). However, consumers' and health providers' views and experiences of formal group partnerships remain unclear. In this qualitative evidence synthesis (QES), we focus specifically on formal group partnerships where health providers and consumers share decision-making about planning, delivering and/or evaluating health services. Formal group partnerships were selected because they are widely used throughout the world to improve person-centred care. For the purposes of this QES, the term 'consumer' refers to a person who is a patient, carer or community member who brings their perspective to health service partnerships. 'Health provider' refers to a person with a health policy, management, administrative or clinical role who participates in formal partnerships in an advisory or representative capacity. This QES was co-produced with a Stakeholder Panel of consumers and health providers. The QES was undertaken concurrently with a Cochrane intervention review entitled Effects of consumers and health providers working in partnership on health services planning, delivery and evaluation. OBJECTIVES: 1. To synthesise the views and experiences of consumers and health providers of formal partnership approaches that aimed to improve planning, delivery or evaluation of health services. 2. To identify best practice principles for formal partnership approaches in health services by understanding consumers' and health providers' views and experiences. SEARCH METHODS: We searched MEDLINE, Embase, PsycINFO and CINAHL for studies published between January 2000 and October 2018. We also searched grey literature sources including websites of relevant research and policy organisations involved in promoting person-centred care. SELECTION CRITERIA: We included qualitative studies that explored consumers' and health providers' perceptions and experiences of partnering in formal group formats to improve the planning, delivery or evaluation of health services. DATA COLLECTION AND ANALYSIS: Following completion of abstract and full-text screening, we used purposive sampling to select a sample of eligible studies that covered a range of pre-defined criteria, including rich data, range of countries and country income level, settings, participants, and types of partnership activities. A Framework Synthesis approach was used to synthesise the findings of the sample. We appraised the quality of each study using the CASP (Critical Appraisal Skill Program) tool. We assessed our confidence in the findings using the GRADE-CERQual (Confidence in the Evidence from Reviews of Qualitative research) approach. The Stakeholder Panel was involved in each stage of the review from development of the protocol to development of the best practice principles. MAIN RESULTS: We found 182 studies that were eligible for inclusion. From this group, we selected 33 studies to include in the final synthesis. These studies came from a wide range of countries including 28 from high-income countries and five from low- or middle-income countries (LMICs). Each of the studies included the experiences and views of consumers and/or health providers of partnering in formal group formats. The results were divided into the following categories. Contextual factors influencing partnerships: government policy, policy implementation processes and funding, as well as the organisational context of the health service, could facilitate or impede partnering (moderate level of confidence). Consumer recruitment: consumer recruitment occurred in different ways and consumers managed the recruitment process in a minority of studies only (high level of confidence). Recruiting a range of consumers who were reflective of the clinic's demographic population was considered desirable, particularly by health providers (high level of confidence). Some health providers perceived that individual consumers' experiences were not generalisable to the broader population whereas consumers perceived it could be problematic to aim to represent a broad range of community views (high level of confidence). Partnership dynamics and processes: positive interpersonal dynamics between health providers and consumers facilitated partnerships (high level of confidence). However, formal meeting formats and lack of clarity about the consumer role could constrain consumers' involvement (high level of confidence). Health providers' professional status, technical knowledge and use of jargon were intimidating for some consumers (high level of confidence) and consumers could feel their experiential knowledge was not valued (moderate level of confidence). Consumers could also become frustrated when health providers dominated the meeting agenda (moderate level of confidence) and when they experienced token involvement, such as a lack of decision-making power (high level of confidence) Perceived impacts on partnership participants: partnering could affect health provider and consumer participants in both positive and negative ways (high level of confidence). Perceived impacts on health service planning, delivery and evaluation: partnering was perceived to improve the person-centredness of health service culture (high level of confidence), improve the built environment of the health service (high level of confidence), improve health service design and delivery e.g. facilitate 'out of hours' services or treatment closer to home (high level of confidence), enhance community ownership of health services, particularly in LMICs (moderate level of confidence), and improve consumer involvement in strategic decision-making, under certain conditions (moderate level of confidence). There was limited evidence suggesting partnering may improve health service evaluation (very low level of confidence). Best practice principles for formal partnering to promote person-centred care were developed from these findings. The principles were developed collaboratively with the Stakeholder Panel and included leadership and health service culture; diversity; equity; mutual respect; shared vision and regular communication; shared agendas and decision-making; influence and sustainability. AUTHORS' CONCLUSIONS: Successful formal group partnerships with consumers require health providers to continually reflect and address power imbalances that may constrain consumers' participation. Such imbalances may be particularly acute in recruitment procedures, meeting structure and content and decision-making processes. Formal group partnerships were perceived to improve the physical environment of health services, the person-centredness of health service culture and health service design and delivery. Implementing the best practice principles may help to address power imbalances, strengthen formal partnering, improve the experiences of consumers and health providers and positively affect partnership outcomes.

RESUMEN

BACKGROUND: genetic testing for cystic fibrosis (CF) has been offered to people with higher risk of being carrier. OBJECTIVES: to assess the effectiveness of population-based CF carrier screening for adults of reproductive age and its optimal organizational features. DESIGN: systematic review. SETTING AND PARTICIPANTS: MedLine, Embase, Cochrane Library, CINAHL and LILACS (1990-2022) were searched to retrieve primary and secondary studies on adults (16 years and older), with no clinical indication or genetic risk, eligible for genetic testing for CF carrier status. MAIN OUTCOMES MEASURES: attitude to screening, uptake of screening offered, informed reproductive choices. RESULTS: a total of 3,326 records were screened and 292 potentially eligible full-text publications assessed. The review included 71 publications, corresponding to 3 reviews, 40 cohort studies (11 comparative, 29 single-arm), and 6 model studies, published between 1992 and 2021 (median 1998). Only one study compared screening or no screening. This study suggested an association between carrier screening and a lower incidence of CF. Comparative studies examined different approaches for invitation and testing, i.e., settings, target population (individuals/couples, prenatal/preconceptional), how invitations are organized (primary care/maternal hospitals), and format and content of the pre-test information. However, no firm conclusions can be drawn on the impact of these features on informed reproductive choices, uptake, and attitude, because of the limitations of the evidence collected. CONCLUSIONS: the broad heterogeneity of the studies, methodological weaknesses, and the limited transferability of the results mean there is still uncertainty about the effectiveness of preconceptional and prenatal CF carrier screening in the general population.

RESUMEN

BACKGROUND: Informed consent forms for clinical research are several and variable at international, national and local levels. According to the literature, they are often unclear and poorly understood by participants. Within the H2020 project CORBEL-Coordinated Research Infrastructures Building Enduring Life-science Services-clinical researchers, researchers in ethical, social, and legal issues, experts in planning and management of clinical studies, clinicians, researchers in citizen involvement and public engagement worked together to provide a minimum set of requirements for informed consent in clinical studies. METHODS: The template was based on a literature review including systematic reviews and guidelines searched on PubMed, Embase, Cochrane Library, NICE, SIGN, GIN, and Clearinghouse databases, and on comparison of templates gathered through an extensive search on the websites of research institutes, national and international agencies, and international initiatives. We discussed the draft versions step-by-step and then we referred to it as the "matrix" to underline its modular character and indicate that it allows adaptation to the context in which it will be used. The matrix was revised by representatives of two international patient groups. RESULTS: The matrix covers the process of ensuring that the appropriate information, context and setting are provided so that the participant can give truly informed consent. It addresses the key topics and proposes wording on how to clarify the meaning of placebo and of non-inferiority studies, the importance of individual participants' data sharing, and the impossibility of knowing in advance how the data might be used in future studies. Finally, it presents general suggestions on wording, format, and length of the information sheet. CONCLUSIONS: The matrix underlines the importance of improving the process of communication, its proper conditions (space, time, setting), and addresses the participants' lack of knowledge on how clinical research is conducted. It can be easily applied to a specific setting and could be a useful tool to identify the appropriate informed consent format for any study. The matrix is mainly intended to support multicentre interventional randomized clinical studies, but several suggestions also apply to non-interventional research.

RESUMEN

The decision aid "Donnainformata-mammografia" (https://www.donnainformata-mammografia.it/en/) has been developed with the aim of providing clear information on the benefits and harms of breast cancer screening, and the controversies on the relationship between mortality reduction and overdiagnosis. It was evaluated in a randomized clinical trial showing it increases informed choice and does not decrease participation in screening.This article describes the framework, the guiding principles, and the operational phases of the tool development.The project was developed within the national screening programme. The promoters decided to state their placement, to start from the information needs of women and what is already known, and to balance spontaneous navigation with "nudging" to key contents. Three focus groups with 18 women and 4 interviews were organized. Participants expressed a favourable attitude towards screening, and no knowledge of the debate on screening efficacy and overdiagnosis. A literature review and a comparison of decision aids were conducted. The online tool included the results of these steps. The home page presents key information with links to relevant topics, so that the person can decide to stop there having an overview or to continue. The «ready to decide¼ button, which leads to the section of decision support, can be clicked on every page. Here, the person can evaluate a list of key points on the basis of her values, in order to decide to participate in screening or not.

RESUMEN

In the past few decades, our understanding of glycan information-encoding power has notably increased, thus leading to a significant growth also in the design and synthesis of glycomimetic probes. Combining data from multiple analytical sources, such as crystallography, nuclear magnetic resonance spectroscopy, and other biophysical methods (eg, surface plasmon resonance and carbohydrate microarrays) has allowed to shed light on the key interaction events between carbohydrates and their protein-targets. However, the low metabolic stability of carbohydrates and their high hydrophilicity, which translates in low bioavailability, undermine their development as drugs. In this framework, the design of chemically modified analogues (called carbohydrate mimics or glycomimetics) appears as a valid alternative for the development of therapeutic agents. Glycomimetics, as structural and functional mimics of carbohydrates, can replace the native ligands in the interaction with target proteins, but are designed to show enhanced enzymatic stability and bioavailability and, possibly, an improved affinity and selectivity toward the target. In the present account, we specifically focus on the most recent advances in the design and synthesis of glycomimetics. In particular, we highlight the efforts of the scientific community in the development of straightforward synthetic procedures for the preparation of sugar mimics and in their preliminary biological evaluation.

RESUMEN

BACKGROUND: Improving the quality of information and communication is a priority in organised breast cancer screening and an ethical duty. Programmes must offer the information each woman is looking for, promoting informed decision-making. This study aimed to develop and evaluate a web-based dynamic decision aid (DA). METHODS: A pragmatic randomised trial carried out in six regional organised screening programmes recruited women at the first invitation receiving DA or a web-based standard brochure (SB). The primary outcome was informed choice measured on knowledge, attitudes, and intentions. Follow-up period: 7-10 days. Secondary outcomes included participation rate, satisfaction, decisional conflict, and acceptability of DA. RESULTS: Two thousand one hundred and nineteen women were randomised and 1001 completed the study. Respectively, 43.9% and 36.9% in the DA and SB reached the informed choice. The DA gave a 13-point higher proportion of women aware about overdiagnosis compared to SB (38.3% versus 25.2%, p < 0.0001). The percentage of women attending screening was the same: 84% versus 83%. Decisional conflict was significantly lower in the DA group (14.4%) than in the SB group (19.3%). CONCLUSION: DA increases informed choice. Complete information including the pros, cons, controversies, and overdiagnosis-overtreatment issues boost a woman's knowledge without reducing the rate of actual screening participation. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov number NCT03097653.

RESUMEN

Cadherins are homophilic cell-cell adhesion molecules whose aberrant expression has often been shown to correlate with different stages of tumor progression. In this work, we investigate the interaction of two peptidomimetic ligands with the extracellular portion of human E-cadherin using a combination of NMR and computational techniques. Both ligands have been previously developed as mimics of the tetrapeptide sequence Asp1-Trp2-Val3-Ile4 of the cadherin adhesion arm, and have been shown to inhibit E-cadherin-mediated adhesion in epithelial ovarian cancer cells with millimolar potency. To sample a set of possible interactions of these ligands with the E-cadherin extracellular portion, STD-NMR experiments in the presence of two slightly different constructs, the wild type E-cadherin-EC1-EC2 fragment and the truncated E-cadherin-(Val3)-EC1-EC2 fragment, were carried out at three temperatures. Depending on the protein construct, a different binding epitope of the ligand and also a different temperature effect on STD signals were observed, both suggesting an involvement of the Asp1-Trp2 protein sequence among all the possible binding events. To interpret the experimental results at the atomic level and to probe the role of the cadherin adhesion arm in the dynamic interaction with the peptidomimetic ligand, a computational protocol based on docking calculations and molecular dynamics simulations was applied. In agreement with NMR data, the simulations at different temperatures unveil high variability/dynamism in ligand-cadherin binding, thus explaining the differences in ligand binding epitopes. In particular, the modulation of the signals seems to be dependent on the protein flexibility, especially at the level of the adhesive arm, which appears to participate in the interaction with the ligand. Overall, these results will help the design of novel cadherin inhibitors that might prevent the swap dimer formation by targeting both the Trp2 binding pocket and the adhesive arm residues.

RESUMEN

Despite concern on the impact of coronavirus disease 2019 (COVID-19) pandemic on undocumented immigrants, quantitative evidence on the issue is scant. We analyze socioeconomic and health conditions of 1590 undocumented immigrants in Milan, Lombardy, one of the regions with the highest COVID-19 clinical burden in the world that does not guarantee access to primary care for these individuals. We document a sharp reduction in visit number after lockdown, with 16% frequency of acute respiratory infections, compatible with COVID-19. Moreover, housing conditions make it difficult to implement public health measures. Results suggest the need to foster primary care by undocumented immigrants to face COVID-19 emergency.

RESUMEN

BACKGROUND: the Covid-19 pandemic has provoked a huge of clinical and epidemiological research initiatives, especially in the most involved countries. However, this very large effort was characterized by several methodological weaknesses, both in the field of discovering effective treatments (with too many small and uncontrolled trials) and in the field of identifying preventable risks and prognostic factors (with too few large, representative and well-designed cohorts or case-control studies). OBJECTIVES: in response to the fragmented and uncoordinated research production on Covid-19, the   italian Association of Epidemiology (AIE) stimulated the formation of a working group (WG) with the aims of identifying the most important gaps in knowledge and to propose a structured research agenda of clinical and epidemiological studies considered at high priority on Covid-19, including recommendations on the preferable methodology. METHODS: the WG was composed by 25 subjects, mainly epidemiologists, statisticians, and other experts in specific fields, who have voluntarily agreed to the proposal. The agreement on a list of main research questions and on the structure of the specific documents to be produced were defined through few meetings and cycles of document exchanges. RESULTS: twelve main research questions on Covid-19 were identified, covering aetiology, prognosis, interventions, follow-up and impact on general and specific populations (children, pregnant women). For each of them, a two-page form was developed, structured in: background, main topics, methods (with recommendations on preferred study design and warnings for bias prevention) and an essential bibliography. CONCLUSIONS: this research agenda represents an initial contribution to direct clinical and epidemiological research efforts on high priority topics with a focus on methodological aspects. Further development and refinements of this agenda by Public Health Authorities are encouraged.

RESUMEN

BACKGROUND: In the framework of 'Doing more does not mean doing better - Choosing Wisely Italy' health professionals, general population and healthcare advocacy associations are widely involved. PartecipaSalute-Mario Negri IRCCS and Altronconsumo organized a survey in order to assess the opinions and behaviors of people toward unnecessary tests and drugs. METHODS: An online survey was distributed by Altroconsumo to a voluntary panel of 6304 Italian citizens covering the whole of the country and by PartecipaSalute-Mario Negri IRCCS through the PartecipaSalute website, e-mail lists, website articles, lay journals and Facebook. RESULTS: In all 1006 people reached by Altroconsumo, and 355 volunteers of healthcare advocacy associations reached by PartecipaSalute responded. Respondents usually decides on their treatment together with the physician, respectively 50% for general population and 64% for volunteers of healthcare advocacy associations. The respondents are aware of the question of over-use of drugs and tests (80%), more often among the volunteers of healthcare advocacy associations (86%). Over-use is considered a problem mostly for economic reasons among the general population, while in the advocacy associations the risks for patients' health is considered more important. CONCLUSION: These findings suggest that patients do not always ask for more, especially if they receive an answer to their questions and clarifications about unnecessary treatments. There is a need for further understanding of the factors influencing decision-making aimed at achieving good care. Engaging the public and patients at all levels of healthcare is essential for a valuable use of health resources.

RESUMEN

OBJECTIVES: to define a list of priorities for activities and research projects based on the consultation of Italian AIDS advocacy groups through an online survey. DESIGN: a multidisciplinary advisory board was set up to define the survey and discuss the findings. Five areas - and related items - were listed: prevention, continuity of care, discrimination, research, key populations. Fifty-eight AIDS advocacy groups were identified and invited through e-mail to the survey, which lasted two months. Responders were asked to select a priority area and vote two items. Then, as second choice, they had to choose up to three items across the other areas. The final step of the prioritization process was the discussion of the survey findings with the advisory board. SETTING AND PARTICIPANTS: Italian HIV advocacy groups. RESULTS: thirty-seven groups responded (64%). The priority selected by most was prevention (around 80%), particularly preventive information addressed to teenagers and the general population. For the second choice, the most chosen items referred to discrimination and the continuity of care. The advisory board members underlined the need for a planned, organized, monitored, and evidence-based approach for HIV prevention information in different settings. CONCLUSIONS: different strategies to provide HIV prevention information should be proposed and monitored according to different targets, following an evidence-based approach. The stigma and discrimination against people with HIV and AIDS must be cleaned up to foster safe sex behaviours, providing education interventions at school. Wider structural issues have to be addressed, such as the availability and affordability of health services, contraceptive choices and condoms, poverty, and cultural gender norms.

RESUMEN

Streptococcus pneumoniae (SP) is a common human pathogen associated with a broad spectrum of diseases and it is still a leading cause of mortality and morbidity worldwide, especially in children. Moreover, SP is increasingly associated with drug resistance. Vaccination against the pathogen may thus represent an important strategy to overcome its threats to human health. In this context, revealing the molecular determinants of SP immunoreactivity may be relevant for the development of novel molecules with therapeutic perspectives as vaccine components. Serogroup 19 comprises the immune-cross reactive types 19F, 19A, 19B and 19C and it accounts for a high percentage of invasive pneumococcal diseases, mainly caused by serotypes 19F and 19A. Herein, we report the synthesis and biological evaluation of an aminopropyl derivative of the trisaccharide repeating unit of SP 19A. We compare two different synthetic strategies, based on different disconnections between the three monosaccharides which make up the final trisaccharide, to define the best approach for the preparation of the trisaccharide. Synthetic accessibility to the trisaccharide repeating unit lays the basis for the development of more complex biopolymer as well as saccharide conjugates. We also evaluate the binding affinity of the trisaccharide for anti-19A and anti-19F sera and discuss the relationship between the chemical properties of the trisaccharide unit and biological activity.

RESUMEN

Neisseria meningitidis serogroup A (MenA) is an aerobic diplococcal Gram-negative bacterium responsible for epidemic meningitis disease. Its capsular polysaccharide (CPS) has been identified as the primary virulence factor of MenA. This polysaccharide suffers from chemical lability in water. Thus, the design and synthesis of novel and hydrolytically stable structural analogues of MenA CPS may provide additional tools for the development of therapies against this disease. In this context, the structural features of the natural phosphorylated monomer have been analyzed and compared to those of its carba-analogue, where the endocyclic oxygen has been replaced by a methylene moiety. The lowest energy geometries of the different molecules have been calculated using a combination of quantum mechanical techniques and molecular dynamics simulations. The predicted results have been compared and validated using NMR experiments. The results indicate that the more stable designed glycomimetics may adopt the conformation adopted by the natural monomer, although they display a wider flexibility around the torsional degrees of freedom.

RESUMEN

Background: Health technology assessment and ethical issues have to be dealt with in deciding on national carrier screening for cystic fibrosis (CF)-the most frequent severe autosomal recessive disease in Caucasian populations and several stakeholders need to be involved. A citizens' jury is one way to ask citizens to deliberate on controversial topics in the interests of a society. The aims of this project were to gather opinions about CF carrier screening through citizens' jury deliberations and to match them with the findings of a large online consultation survey open to the general population, people with CF and families and health professionals. Methods: Three citizens' juries and an online survey were asked: 'Should the Health Service organize screening of the population with the aim of identifying healthy people who may have children with CF?' The jurors had no medical background and no personal or family CF history. The survey was open to people with CF, families, and healthcare professionals. Results: Jurors and survey respondents were in favour of CF carrier screening, mainly considering the severity of CF, the value of informed reproductive choices and the equality of the screening. All the citizens' juries felt positively about the health service actively offer CF carrier screening to provide women and couples of reproductive age equal access and standardized information on the pros and cons. Conclusion: Considering the favourable attitude towards CF screening, the feasibility of CF screening, in terms of best setting, target age and healthcare professionals providing it, should be tested in a clinical trial.

RESUMEN

During the last decade there has been a growing interest in glycoimmunology, a relatively new research field dealing with the specific interactions of carbohydrates with the immune system. Pathogens' cell surfaces are covered by a thick layer of oligo- and polysaccharides that are crucial virulence factors, as they mediate receptors binding on host cells for initial adhesion and organism invasion. Since in most cases these saccharide structures are uniquely exposed on the pathogen surface, they represent attractive targets for vaccine design. Polysaccharides isolated from cell walls of microorganisms and chemically conjugated to immunogenic proteins have been used as antigens for vaccine development for a range of infectious diseases. However, several challenges are associated with carbohydrate antigens purified from natural sources, such as their difficult characterization and heterogeneous composition. Consequently, glycoconjugates with chemically well-defined structures, that are able to confer highly reproducible biological properties and a better safety profile, are at the forefront of vaccine development. Following on from our previous review on the subject, in the present account we specifically focus on the most recent advances in the synthesis and preliminary immunological evaluation of next generation glycoconjugate vaccines designed to target bacterial and fungal infections that have been reported in the literature since 2011.

RESUMEN

BACKGROUND: In Italy women aged 50-69 are invited for a population-based breast cancer (BC) screening. Physicians, policy makers and patients associations agree on the need to inform women about the benefits and harms in order to permit an informed decision. Decision aids (DA) are an effective way to support people in their decisions about health. This trial aims to assess women's informed choices, according to their health literacy and values, on participating or not in BC screening for the first time. Benefits, harms and controversies are presented. METHODS/DESIGN: The impact of the DA will be evaluated in a randomized controlled trial with a two-week follow-up. Women will be randomized via web to DA or a standard brochure. We will invite 8160 women, to obtain a final sample of 816 women. The primary outcome will be informed choice, measured on the basis of knowledge, attitudes and intentions on BC screening. Secondary outcomes are participation rate, satisfaction on information and decisional conflict. DISCUSSION: The web DA will be open-source and implemented on BC screenings and its efficacy for increasing informed choice will be tested. This model could be applied to other healthcare settings, cancer screenings, and public health programs. TRIAL REGISTRATION: The protocol for this trial was registered with the Clinicaltrials.gov registry on March 16, 2017: NCT03097653 .

RESUMEN

We describe the formation of a bis-cyclopropane product, a tricyclic[4.1.0.02,4]heptane, that is formed during a Johnson-Corey-Chaykovsky reaction on a cyclopentenone. Two (of four possible) bicyclic products are selectively formed by addition of a COOEt-stabilized sulfur ylide onto the Michael acceptor. The tricyclic product is formed subsequently via a retro Michael elimination of a hindered ether followed by addition of a further cyclopropyl moiety, affecting only one of the two bicyclic products initially formed. The experimental reaction outcome was rationalized using density functional theory (DFT), investigating the different Michael-addition approaches of the sulfur ylide, the transition state (TS) energies for the formation of possible zwitterionic intermediates and subsequent reactions that give rise to cyclopropanation. Selective formation of only two of the four possible products occurs due to the epimerization of unreactive intermediates from the other two pathways, as revealed by energy barrier calculations. The formation of the tricyclic product was rationalized by evaluation of energy barriers for proton abstraction required to form the intermediate undergoing the second cyclopropanation. The selectivity-guiding factors discussed for the single and double cyclopropanation of this functionalized Michael-acceptor will be useful guidelines for the synthesis of future singly and doubly cyclopropanated compounds.

RESUMEN

The synthesis and conformational analysis of pseudo-thio-1,2-dimannoside are described. This molecule mimics mannobioside (Manα(1,2)Man) and is an analog of pseudo-1,2-dimannoside, with expected increased stability to enzymatic hydrolysis. A short and efficient synthesis was developed based on an epoxide ring-opening reaction by a mannosyl thiolate, generated in situ from the corresponding thioacetate. NMR-NOESY studies supported by MM3∗ calculations showed that the pseudo-thio-1,2-dimannoside shares the conformational behavior of the pseudo-1,2-dimannoside and is a structural mimic of the natural disaccharide. Its affinity for DC-SIGN was measured by SPR and found to be comparable to the corresponding O-linked analog, offering good opportunities for further developments.
