Abstract
OBJECTIVE To investigate the relationship between perception of craniofacial deformity, geometric head features, and 3D head shape analyzed by statistical shape modeling (SSM). PATIENTS A total of 18 unoperated patients with scaphocephaly (age = 5.2 ± 1.1m)-6 were followed-up after spring-assisted cranioplasty (SAC) (age = 9.6 ± 1.5m)-and 6 controls (age = 6.7 ± 2.5m). MAIN OUTCOME MEASURES 3D head shapes were retrieved from 3D scans or computed tomography (CTs). Various geometrical features were measured: anterior and posterior prominence, take-off angle, average anterior and posterior lateral and horizontal curvatures, cranial index (CI) (cranial width over length), and turricephaly index (TI) (cranial height over length). SSM and principal component analysis (PCA) described shape variability. All models were 3D printed; the perception of deformity was blindly scored by 9 surgeons and 1 radiologist in terms of frontal bossing (FB), occipital bulleting (OB), biparietal narrowing (BN), low posterior vertex (LPV), and overall head shape (OHS). RESULTS A moderate correlation was found between FB and anterior prominence (r = 0.56, P < .01) and take-off angle (r = - 0.57, P < .01). OB correlated with average posterior lateral curvature (r = 0.43, P < 0.01) similarly to BPN (r = 0.55, P < .01) and LPV (r = 0.43, P < .01). OHS showed strong correlation with CI (r = - 0.68, P < .01) and TI (r = 0.63, P< .01). SSM Mode 1 correlated with OHS (r = 0.66, p < .01) while Mode 3 correlated with FB (r = - 0.58, P < .01). CONCLUSIONS Esthetic cranial appearance in craniofacial patients is correlated to specific geometric parameters and could be estimated using automated methods such as SSM.

Abstract
The Ma_MISS miniaturized spectrometer is integrated within the Drilling System of the ExoMars Rosalind Franklin Rover for Mars exploration. Here we focus on the on ground calibration campaign to obtain radiometric and linearity calibrations of the Ma_MISS instrument, while the first paper dealt with the spectral calibration [De Angelis et al., Rev. Sci. Instrum. 93, 123704 (2022)]. The experimental setup used to carry out radiometric calibration is described, as are the methods used for data processing and key parameter retrieval. In particular, the Spectrometer Transfer Function (Responsivity), Signal-to-Noise Ratio, and detector linearity are determined. In a third paper [De Sanctis et al., Planet. Sci. J. 3, 142 (2022)], validation of the Ma_MISS calibration results through spectral measurements performed on rock and synthetic targets during the radiometric calibration campaign is described.

Abstract
Purpose Sliding genioplasty is used to surgically correct a retruded or misaligned chin: in this procedure, an osteotomy is performed and the bony segment is repositioned. In this study we investigate the effect of surgical parameters (bony segment movement, osteotomy design) on postop soft tissue changes in a patient cohort. Methods Seven patients were retrospectively recruited. Cone beam computed tomography data were obtained and soft tissue and bone shape reconstructions were performed. 3D models were created and surgical cuts were replicated according to postop scans. Each model was imported in ANSYS 2019R1 (Ansys Inc, USA) for simulation: the effect of variation in osteotomy plane as well as extent of bony segment movement were assessed by means of design of experiment: surgical parameters were varied in a surgically acceptable range and the soft tissue predictions were evaluated as displacement output of five craniometric landmarks. Results Simulation results show the overall changes of the lower third of the face are sensitive to changes in horizontal and vertical displacement of the bony segment as well as segment rotation. No significant changes in the soft tissue response were to attribute to the osteotomy design. Conclusions Our results are consistent with experimental findings reported in the literature: when planning genioplasty in orthognathic surgery, particular focus on the segment movement (horizontal translation, vertical translation and rotation), rather than on the design of the osteotomy itself, should be considered.

Abstract
BACKGROUND Esthesioneuroblastoma (ENB) is an uncommon neuroectodermal tumor that originates from the olfactory mucosa and often recurs locally. Distant metastases of ENB have been described, but there are few reports of intramedullary metastases to the spinal cord. CASE DESCRIPTION Here we report a case of a patient presenting with a progressive paraparesis and magnetic resonance imaging findings of multiple drop metastases to thoracic and lumbar regions of the spinal cord, 17 years after diagnosis and treatment for an intracranial ENB with subsequent neck nodal metastases. The dorsal symptomatic lesion was treated with resection, radiotherapy, and adjuvant chemotherapy. The implications of spinal metastases for the clinical prognosis of this disease are discussed, with a review of the few reported cases of spinal ENB metastases in the literature. CONCLUSIONS Through the presentation of this case we hope to further contribute to a better understanding of this rare disease's prognosis.

Abstract
IMPORTANCE Sophisticated evidence-based information resources can filter medical evidence from the literature, integrate it into electronic health records, and generate recommendations tailored to individual patients. OBJECTIVE To assess the effectiveness of a computerized clinical decision support system (CDSS) that preappraises evidence and provides health professionals with actionable, patient-specific recommendations at the point of care. DESIGN, SETTING, AND PARTICIPANTS Open-label, parallel-group, randomized clinical trial among internal medicine wards of a large Italian general hospital. All analyses in this randomized clinical trial followed the intent-to-treat principle. Between November 1, 2015, and December 31, 2016, patients were randomly assigned to the intervention group, in which CDSS-generated reminders were displayed to physicians, or to the control group, in which reminders were generated but not shown. Data were analyzed between February 1 and July 31, 2018. INTERVENTIONS Evidence-Based Medicine Electronic Decision Support (EBMEDS), a commercial CDSS covering a wide array of health conditions across specialties, was integrated into the hospital electronic health records to generate patient-specific recommendations. MAIN OUTCOMES AND MEASURES The primary outcome was the resolution rate, the rate at which medical problems identified and alerted by the CDSS were addressed by a change in practice. Secondary outcomes included the length of hospital stay and in-hospital all-cause mortality. RESULTS In this randomized clinical trial, 20 563 patients were admitted to the hospital. Of these, 6480 (31.5%) were admitted to the internal medicine wards (study population) and randomized (3242 to CDSS and 3238 to control). The mean (SD) age of patients was 70.5 (17.3) years, and 54.5% were men. In total, 28 394 reminders were generated throughout the course of the trial (median, 3 reminders per patient per hospital stay; interquartile range [IQR], 1-6). These messages led to a change in practice in approximately 4 of 100 patients. The resolution rate was 38.0% (95% CI, 37.2%-38.8%) in the intervention group and 33.7% (95% CI, 32.9%-34.4%) in the control group, corresponding to an odds ratio of 1.21 (95% CI, 1.11-1.32; P < .001). The length of hospital stay did not differ between the groups, with a median time of 8 days (IQR, 5-13 days) for the intervention group and a median time of 8 days (IQR, 5-14 days) for the control group (P = .36). In-hospital all-cause mortality also did not differ between groups (odds ratio, 0.95; 95% CI, 0.77-1.17; P = .59). Alert fatigue did not differ between early and late study periods. CONCLUSIONS AND RELEVANCE An international commercial CDSS intervention marginally influenced routine practice in a general hospital, although the change did not statistically significantly affect patient outcomes.

Abstract
Abstract
Introduction
Barrett’s esophagus (BE) is a well-known precursor to esophageal adenocarcinoma (EAC). Simple BE has an annual rate of progression to EAC of only up to 0.5%, while BE with low-grade dysplasia (LGD) or with high-grade dysplasia (HGD) has a higher progression rate of ~10% and ~40%, respectively. Therefore, accurate diagnosis and grading of dysplasia in BE are critical for optimal patient management. However, grading dysplasia is not well defined in practice, which often results in poor interobserver and/or intraobserver reproducibility. In this study, we aim to (1) investigate the concordance of intradepartmental consultations of BE dysplasia and (2) compare consultant diagnosis with final diagnosis and follow-up diagnosis.
Methods
We retrospectively reviewed 856 intradepartmental consultation records obtained from May 2017 to March 2018. For cases of Barrett’s dysplasia in biopsy specimens, H&E-stained slides were re-reviewed and the corresponding clinical information was retrieved from the electronic medical record.
Results
Twenty intradepartmental consultation cases of Barrett’s dysplasia were identified (involving 2 females and 18 males, mean age 67.8 ± 8.6 years, ranging 50-81 years). The most frequent reasons for consultation were indefinite dysplasia (IND) vs LGD and LGD vs HGD. Half of the cases showed concordance between referring pathologist and consultant pathologist(s), while 10% of the case showed a major discrepancy (resulting in significant changes in patient management and/or prognosis) and 40% showed a minor discrepancy (resulting in no significant impact on patient management and/or prognosis). The final diagnoses were changed after consultation for cases with major discrepancy, while 60% of cases with minor discrepancy remained the original diagnoses.
Conclusions
Intradepartmental consultations are strongly recommended for the challenging cases of BE dysplasia, which can effectively prevent over- or underdiagnosis. For challenging cases such as IND vs LGD, two or more consultants are usually needed to reach an agreement.

Abstract
INTRODUCTION INTRODUCTION The knowledge of principles and methods of Evidence Based Medicine (EBM) and the use of Clinical Practice Guidelines to inform clinical decisions are recognised as key instruments to improve the quality of care. In Italy the Parliament has revised the legal system that rules the responsibilities of health professionals and health care safety, prescribing health professionals to adhere to guidelines and good practice recommendations. The objective of the study was to evaluate guidelines and clinical pathways developed at local level and to assess knowledge and attitudes of healthcare workers toward EBM and guidelines. METHODS At the l'ASL 5 Liguria La Spezia we performed a census of all the documents registered as "guidelines" or "clinical pathways" at the Direzione Generale by the end of May 2016. We assessed their methodological quality by the "Recognition Card for Clinical Pathways Production and Revision Activity" prepared by the Ligurian Region. We conducted semi-structured interviews to assess attitudes and knowledge of healthcare workers. RESULTS We found 17 clinical pathways, 41% contained organizational/management recommendations, and 59% contained mainly clinical recommendations. 41% was produced by assimilating already existing guidelines. 29% did not describe the method of production. Only one document linked directly each recommendation with scientific evidence. 10 healthcare workers out of 32 invited actually accepted to conduct the interview. Respondents showed a positive attitude toward the EBM and guidelines but a poor knowledge of the methodology of production and the instruments and principles for critical appraising of scientific literature. Nobody knew the GRADE approach. The most relevant barriers identified were: lack of time, poor knowledge of English and statistical methods, poor applicability of the international guidelines to local setting and real patients encountered in clinical practice. DISCUSSION Despite the initiatives of the legislator toward civil responsibility and safety of care that should increase the use of guidelines, we found an overall poor knowledge of the concepts of EBM and method of guidelines production. Though the attitudes of responders to the interview were positive, barriers to use seemed to be predominant and considered more as obstacles than as a stimulus. In peripheral settings or in hospitals of medium/small size, clinical guidelines could remain confined to a merely juridical role, with weak impact on professional practice.

Abstract
Non-immune hydrops fetalis (NIHF) has a high mortality rate [1]. Many etiologies of NIHF have been identified, including cardiovascular abnormalities, severe anemia, and genetic defects. In patients with cardiovascular etiology, structural malformations lead to fluid accumulation resulting in increased intravascular hydrostatic pressure. We report a fatal case of NIHF in a 31 week gestational age, Caucasian neonate with heart remodeling associated with a stenotic vasculopathy of the right pulmonary artery. The artery revealed partial occlusion with vascular wall abnormalities, including disarrayed smooth muscle fibers, hyperplasia within the tunica media, and myxoid change within the media and intima. Identical vasculopathy was also identified within a mesenteric artery, and this contributed to hemorrhage and early ischemic necrosis of the small intestine, discovered on postmortem examination.

Abstract
Endocarditis is a cardiovascular disease caused by the inflammation of the inner tissues of the heart, the endocardium, usually of the valves. Bacteraemia is essential in the development of endocarditis, and there are some findings that the main pathogens of endocarditis are viridans group streptococci: Streptococcus oralis, Streptococcus sanguinis, and Enterococcus faecalis. There is strong evidence that endocarditis bacteria are present in the tonsillar microbiota, so that tonsillar infection is associated with an increased risk of endocarditis. The aim of this manuscript is to investigate the presence of the main pathogens of endocarditis in tonsillar microbiota of an Afghan population group. A sample of 80 tonsil swabs were analyzed by quantitative real time PCR to detect endocarditis pathogens and an estimation of the total bacterial load. The median bacterial load in PCR reaction was 1.4x106 (interquartile range 4,7x105 - 2,9x106). Three species, S. Oralis, S. Sanguinis, and E. Faecalis were found in large amounts in all specimens. On the other hand, S. Mitis was never detected. The S. Aureus was found in 3 samples with a prevalence of 0.04 (C.I. 0.01-0.10). The S. Mutans was found in 33 samples with a prevalence of 0.41 (C.I. 0.31-0.52). Endocarditis bacteria has been found into the tonsillar microbiota, so there is sufficient evidence to justify that the oral cavity is a reservoir of endocarditis bacteria that can have a significant impact on the cardiovascular function.

Abstract
Some studies have evidenced the role of human polyomaviruses in head and neck squamous cell carcinoma. BK, JC and SV40 human polyoma viruses are widely recognized as etiological agents associated with malignancies. The aim of this study was to analyse the prevalence of BK, IC and SV40 in tonsillar microbiota in a group of Afghan volunteers. A sample of the tonsillar microbiota was taken from a single site using a sterile oral swab paper stick. A fixed volume of purified DNA from each sample was tested by quantitative real-time polymerase chain reactions to evaluate the number of human cells and the number of viral genomes in each sample. The cell number was evaluated via the quantification of a single copy genomic sequence, which is located in the HMBS locus. The median analyzed cell number in each reaction was 4343 (interquartile range 2074-8470). SV40 was never detected, while prevalence rate was 0.11 (C.I. 0.06-0.20) for BK and 0.10 (C.I. 0.05-0.19) for JC. Further studies are necessary to clarify whether polyomaviruses can be considered a risk factor of oral, oropharyngeal and laryngeal malignancies.

Abstract
Cancer of the oral cavity is known to have a diverse aetiology that includes infectious agents. Human papilloma virus has been found to be associated with several types of human cancer, inclusive of cervical, vulvar, vaginal, penile, anal, and cancer of tonsil. The aim of this manuscript is to investigate the presence of human papilloma virus in tonsillar microbiota of an Afghan population group. A sample of the tonsillar microbiota was collected by oral swab paper stick from 80 healthy donors. The sample was investigated for the presence of high-risk human papillomavirus types 16, 18, 31 and 45 by real time PCR. Eight samples produced some positive endpoint signals for human papillomaviruses. The human papillomavirus 31 was the unique papillomavirus detected; its calculated prevalence rate was 0.10 (C.I. 0.05-0.19). However, the viral load was always very low, in the order of 10-3 viral genomes per cell. The high prevalence of high-risk human papillomavirus in healthy population suggest a need for further investigation on virus spreading and supports the development of vaccination strategies.

Abstract
BACKGROUND Advanced Computerized Decision Support Systems (CDSSs) assist clinicians in their decision-making process, generating recommendations based on up-to-date scientific evidence. Although this technology has the potential to improve the quality of patient care, its mere provision does not guarantee uptake: even where CDSSs are available, clinicians often fail to adopt their recommendations. This study examines the barriers and facilitators to the uptake of an evidence-based CDSS as perceived by diverse health professionals in hospitals at different stages of CDSS adoption. METHODS Qualitative study conducted as part of a series of randomized controlled trials of CDSSs. The sample includes two hospitals using a CDSS and two hospitals that aim to adopt a CDSS in the future. We interviewed physicians, nurses, information technology staff, and members of the boards of directors (n = 30). We used a constant comparative approach to develop a framework for guiding implementation. RESULTS We identified six clusters of experiences of, and attitudes towards CDSSs, which we label as "positions." The six positions represent a gradient of acquisition of control over CDSSs (from low to high) and are characterized by different types of barriers to CDSS uptake. The most severe barriers (prevalent in the first positions) include clinicians' perception that the CDSSs may reduce their professional autonomy or may be used against them in the event of medical-legal controversies. Moving towards the last positions, these barriers are substituted by technical and usability problems related to the technology interface. When all barriers are overcome, CDSSs are perceived as a working tool at the service of its users, integrating clinicians' reasoning and fostering organizational learning. CONCLUSIONS Barriers and facilitators to the use of CDSSs are dynamic and may exist prior to their introduction in clinical contexts; providing a static list of obstacles and facilitators, irrespective of the specific implementation phase and context, may not be sufficient or useful to facilitate uptake. Factors such as clinicians' attitudes towards scientific evidences and guidelines, the quality of inter-disciplinary relationships, and an organizational ethos of transparency and accountability need to be considered when exploring the readiness of a hospital to adopt CDSSs.

Abstract
Background: Topical corticosteroids have proven efficacy in the treatment of eosinophilic esophagitis (EoE) and are considered the cornerstone of therapy. Objective: To evaluate the effect of topical beclomethasone dipropionate (BDP) therapy on clinical outcomes, esophageal eosinophilia, and other markers of inflammation in patients with EoE. Methods: Nine subjects with a biopsy-proven diagnosis of EoE were enrolled. In a cross-over design, the subjects were randomly assigned to a sequence of BDP and placebo. Treatment periods were 8 weeks, with a 4-week washout period. The subjects had endoscopic biopsies and blood tests at baseline and after each treatment period. They were instructed to maintain a diary of symptoms. Immuno-histochemical studies were performed for interleukins IL-4, IL-5, IL-13, granulocyte-macrophage colony-stimulating factor (GM-CSF), and transforming growth factor (TGF) beta. Reverse transcription polymerase chain reaction was performed for IL-3, IL-4, IL-5, IL-10, IL-13, IL-17F, IL-25, IL-33, chemokine ligands (CCL)2, CCL5, CCL11, GM-CSF, and TGF-beta levels. The mast cell tryptase (MCT) level was measured in esophageal tissues. Results: BDP led to a significantly larger decrease in esophageal eosinophilia compared with placebo, but there was no significant change in peripheral eosinophilia and high-sensitivity C-reactive protein between the two groups. The study was not powered enough for us to report a significant improvement in clinical symptoms. There was a significant decrease in tissue IL-13 and MCT levels from baseline to the end of treatment between the treatment and placebo groups. Mean fold decreases in cytokine expression between the baseline and treatment groups were observed for IL-17F, IL-25, CCL2, and CCL5. Conclusion: Treatment with topical BDP was associated with significant decrease in esophageal eosinophilia, MCT and IL-13. BDP is a potential alternative to fluticasone propionate and budesonide for treatment of EoE. Larger studies are needed to validate these findings.

Abstract
BACKGROUND Computerized decision support systems (CDSSs) are computer programs that provide doctors with person-specific, actionable recommendations, or management options that are intelligently filtered or presented at appropriate times to enhance health care. CDSSs might be integrated with patient electronic health records (EHRs) and evidence-based knowledge. METHODS/DESIGN The Computerized DEcision Support in ONCOlogy (ONCO-CODES) trial is a pragmatic, parallel group, randomized controlled study with 1:1 allocation ratio. The trial is designed to evaluate the effectiveness on clinical practice and quality of care of a multi-specialty collection of patient-specific reminders generated by a CDSS in the IRCCS Istituto Scientifico Romagnolo per lo Studio e la Cura dei Tumori (IRST) hospital. We hypothesize that the intervention can increase clinician adherence to guidelines and, eventually, improve the quality of care offered to cancer patients. The primary outcome is the rate at which the issues reported by the reminders are resolved, aggregating specialty and primary care reminders. We will include all the patients admitted to hospital services. All analyses will follow the intention-to-treat principle. DISCUSSION The results of our study will contribute to the current understanding of the effectiveness of CDSSs in cancer hospitals, thereby informing healthcare policy about the potential role of CDSS use. Furthermore, the study will inform whether CDSS may facilitate the integration of primary care in cancer settings, known to be usually limited. The increasing use of and familiarity with advanced technology among new generations of physicians may support integrated approaches to be tested in pragmatic studies determining the optimal interface between primary and oncology care.

Abstract
INTRODUCTION One of the aims of Evidence-Based Medicine is to improve quality and appropriateness of care by the expedition of the knowledge transfer process. Computerized Decision Support Systems (CDSSs) are computer programs that provide alerts to the prescribing doctor directly at the moment of medical examination. In fact, alerts are integrated within the single patient electronic health record. CDSS based on the best available and updated evidence and guidelines may be an efficient tool to facilitate the transfer of the latest results from clinical research directly at the bedside, thus supporting decision-making. OBJECTIVES The CODES (COmputerized DEcision Support) trial is a research program funded by the Italian Ministry of Health and the Lombardy Region. It aims to evaluate the feasibility of the implementation of a CDSS at the hospital level and to assess its efficacy in daily clinical practice. METHODS The CODES project includes two pragmatic RCTs testing a CDSS (i.e. the EBMeDS - MediDSS) in two large Italian hospitals: the first is a general hospital in Vimercate (Lombardy), the second is an oncologic research center in Meldola (Emilia Romagna). The CDSS supports a full spectrum of decisions: therapy, drug interactions, diagnosis, and management of health care services are covered by a hundreds of reminders. However only few reminders are activated per patient, highlighting crucial problems in the delivery of high-quality care. The two trials have similar design and primary outcome, the rate at which alerts detected by the software are resolved by a decision of the clinicians. The project also includes the assessment of barriers and facilitators in the adoption of these new technologies by hospital staff members and the retrospective evaluation of the repeated risks in prescription habits. RESULTS The trials are ongoing and currently more than 10,000 patients have been randomized. The qualitative analysis revealed a progressive shift in the perception of the tool. Doctors are now seeing it as a trusted second opinion, available 24/7, which is tailored to the needs of the patient. The retrospective analysis showed the opportunity to achieve a better healthcare quality through an active risk management. Aggregating data from whole hospitals emerge rare drug interactions that otherwise would not be recognizable. DISCUSSION CDSS are promising tools to support clinicians in everyday practice. They can be used as a real time app or to perform retrospective analyses. These data can provide unique resources to hospital management.

Abstract
BACKGROUND Computerized decision support systems (CDSSs) are information technology-based software that provide health professionals with actionable, patient-specific recommendations or guidelines for disease diagnosis, treatment, and management at the point-of-care. These messages are intelligently filtered to enhance the health and clinical care of patients. CDSSs may be integrated with patient electronic health records (EHRs) and evidence-based knowledge. METHODS/DESIGN We designed a pragmatic randomized controlled trial to evaluate the effectiveness of patient-specific, evidence-based reminders generated at the point-of-care by a multi-specialty decision support system on clinical practice and the quality of care. We will include all the patients admitted to the internal medicine department of one large general hospital. The primary outcome is the rate at which medical problems, which are detected by the decision support software and reported through the reminders, are resolved (i.e., resolution rates). Secondary outcomes are resolution rates for reminders specific to venous thromboembolism (VTE) prevention, in-hospital all causes and VTE-related mortality, and the length of hospital stay during the study period. DISCUSSION The adoption of CDSSs is likely to increase across healthcare systems due to growing concerns about the quality of medical care and discrepancy between real and ideal practice, continuous demands for a meaningful use of health information technology, and the increasing use of and familiarity with advanced technology among new generations of physicians. The results of our study will contribute to the current understanding of the effectiveness of CDSSs in primary care and hospital settings, thereby informing future research and healthcare policy questions related to the feasibility and value of CDSS use in healthcare systems. This trial is seconded by a specialty trial randomizing patients in an oncology setting (ONCO-CODES).

Abstract
INTRODUCTION Decision makers adopt interventions, including vaccines, which are most beneficial to populations. A transparent, unbiased, and comprehensive framework based on evidence-based criteria is a promising tool to guide decision-making on vaccine adoption: we developed a multi-dimensional framework conceived from the DECIDE - Evidence to decision Framework (EtD framework). We validated the framework by conducting a real data and evidence set collection on varicella vaccination and tested it with a multidisciplinary group. METHODS The EtD framework presented evidence concerning the varicella vaccination organized in six dimensions: Burden of disease, Vaccine characteristics and impact of immunization program, Values and preferences, Resource use, Equity and Feasibility. Two reviewers completed each dimension with information about varicella vaccine. A multidisciplinary group of 42 participants were asked to evaluate the information in the framework, decide whether to introduce varicella vaccine in the national immunization program, assess the usefulness, and propose some impovements of the decision-making tool. RESULTS From 33 responders (79%) out of 42, 61% supported the adoption of the varicella vaccine as part of the national immunization program. A half (50%) favored the monovalent vaccine while the other half chose the tetravalent vaccine. About 90% of responders found information in the EtD framework comprehensive, easy to understand, and presented in a way that helped make decisions. CONCLUSIONS Complete and transparent information are welcome. The EtD identified a situation of important divergences between policy makers regarding the introduction and the choice of vaccine. In our case study, for example, a third of the multidisciplinary group did not recommend the adoption of varicella vaccine.

Abstract
INTRODUCTION Computerized Decision Support Systems (CDSSs) connect health care professionals with high-quality, evidence-based information at the point-of-care to guide clinical decision-making. Current research shows the potential of CDSSs to improve the efficiency and quality of patient care. The mere provision of the technology, however, does not guarantee its uptake. This qualitative study aims to explore the barriers and facilitators to the use of CDSSs as identified by health providers. METHODS The study was performed in three Italian hospitals, each characterized by a different level of familiarity with the CDSS technology. We interviewed frontline physicians, nurses, information technology staff, and members of the hospital board of directors (n=24). A grounded theory approach informed our sampling criteria as well as the data collection and analysis. RESULTS The adoption of CDSSs by health care professionals can be represented as a process that consists of six "positionings," each corresponding to an individual's use and perceived mastery of the technology. In conditions of low mastery, the CDSS is perceived as an object of threat, an unfamiliar tool that is difficult to control. On the other hand, individuals in conditions of high mastery view the CDSS as a helpful tool that can be locally adapted and integrated with clinicians' competences to fulfil their needs. In the first positionings, the uptake of CDSSs is hindered by representational obstacles. The last positionings, alternatively, featured technical obstacles to CDSS uptake. DISCUSSION Our model of CDSS adoption can guide hospital administrators interested in the future integration of CDSSs to evaluate their organizational contexts, identify potential challenges to the implementation of the technology, and develop an effective strategy to address them. Our findings also allow reflections concerning the misalignment between most Italian hospitals and the current innovation trends toward the uptake of computerized decision support technologies.

Abstract
We systematically reviewed randomized controlled trials (RCTs) assessing the effectiveness of computerized decision support systems (CDSSs) featuring rule- or algorithm-based software integrated with electronic health records (EHRs) and evidence-based knowledge. We searched MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, and Cochrane Database of Abstracts of Reviews of Effects. Information on system design, capabilities, acquisition, implementation context, and effects on mortality, morbidity, and economic outcomes were extracted. Twenty-eight RCTs were included. CDSS use did not affect mortality (16 trials, 37395 patients; 2282 deaths; risk ratio [RR] = 0.96; 95% confidence interval [CI] = 0.85, 1.08; I(2) = 41%). A statistically significant effect was evident in the prevention of morbidity, any disease (9 RCTs; 13868 patients; RR = 0.82; 95% CI = 0.68, 0.99; I(2) = 64%), but selective outcome reporting or publication bias cannot be excluded. We observed differences for costs and health service utilization, although these were often small in magnitude. Across clinical settings, new generation CDSSs integrated with EHRs do not affect mortality and might moderately improve morbidity outcomes.

Abstract
BACKGROUND Computerized clinical decision support systems (CDSSs) have been shown to improve the efficiency and quality of patient care by connecting healthcare professionals with high quality, evidence-based information at the point-of-care. The mere provision of CDSSs, however, does not guarantee their uptake. Rather, individual and institutional perceptions can foster or inhibit the integration of CDSSs into routine clinical workflow. Current studies exploring health professionals' perceptions of CDSSs focus primarily on technical and usability issues, overlooking the social or cultural variables as well as broader administrative or organizational roles that may influence CDSS adoption. Moreover, there is a lack of data on the evolution of perceived barriers or facilitators to CDSS uptake across different stages of implementation. METHODS We will conduct a qualitative, cross-sectional study in three Italian specialty hospitals involving frontline physicians, nurses, information technology staff, and members of the hospital board of directors. We will use semi-structured interviews following the Grounded Theory framework, progressively recruiting participants until no new information is gained from the interviews. DISCUSSION CDSSs are likely to become an integral and diffuse part of clinical practice. Various factors must be considered when planning their introduction in healthcare settings. The findings of this study will guide the development of strategies to facilitate the successful integration of CDSSs into the regular clinical workflow. The evaluation of diverse health professionals across multiple hospital settings in different stages of CDSS uptake will better capture the complexity of roles and contextual factors affecting CDSS uptake.

Abstract
BACKGROUND Endogenous opioid peptides have been shown to play a role in the development and/or perpetuation of inflammation. We hypothesize that the endogenous opioid system is involved in inflammatory bowel disease, and antagonism of the opioid-opioid receptor will lead to reversal of inflammation. AIMS A randomized double-blind placebo-controlled study was designed to test the efficacy and safety of an opioid antagonist for 12 weeks in adults with active Crohn's disease. METHODS Forty subjects with active Crohn's disease were enrolled in the study. Randomized patients received daily oral administration of 4.5-mg naltrexone or placebo. Providers and patients were masked to treatment assignment. The primary outcome was the proportion of subjects in each arm with a 70-point decline in Crohn's Disease Activity Index score (CDAI). The secondary outcome included mucosal healing based upon colonoscopy appearance and histology. RESULTS Eighty-eight percent of those treated with naltrexone had at least a 70-point decline in CDAI scores compared to 40% of placebo-treated patients (p = 0.009). After 12 weeks, 78% of subjects treated with naltrexone exhibited an endoscopic response as indicated by a 5-point decline in the Crohn's disease endoscopy index severity score (CDEIS) from baseline compared to 28% response in placebo-treated controls (p = 0.008), and 33% achieved remission with a CDEIS score <6, whereas only 8% of those on placebo showed the same change. Fatigue was the only side effect reported that was significantly greater in subjects receiving placebo. CONCLUSIONS Naltrexone improves clinical and inflammatory activity of subjects with moderate to severe Crohn's disease compared to placebo-treated controls. Strategies to alter the endogenous opioid system provide promise for the treatment of Crohn's disease.

Abstract
AIM Early recurrence of atrial fibrillation (AF) is common after electrical cardioversion (ECV). Accurate prediction of AF recurrence might allow more selective use of ECV and the targeted use of antiarrhtyhmic therapy in those at highest risk of recurrence. METHODS We have screened consecutive patients attending for cardioversion of AF and recruited those without valvular heart disease, heart failure or permanent pacemakers. All patients underwent echocardiography and measurement of serum BNP levels within 24 hours before ECV. Measurement of BNP was repeated at 1, 7, 30 and 90 days after ECV and an ECG recorded on each occasion. RESULTS We have screened 24 consecutive patients. Five were excluded. All 19 study subjects were succesfully cardioverted to sinus rhythm. AF recurred in nine cases. Recurrence of AF was associated with AF duration, left atrial size, the presence of hypertension and the BNP level before cardioversion. BNP fell significantly after cardioversion. The BNP level after cardioversion was not associated with AF recurrence. CONCLUSION Even in persons without valvular heart disease or heart failure, an elevated level of BNP predicts recurrence of AF after ECV. The level to which BNP falls after cardioversion is not predictive of AF recurrence.

Abstract
BACKGROUND In 1996, the National Cancer Institute hosted an international workshop to develop criteria to identify patients with colorectal cancer who should be offered microsatellite instability (MSI) testing due to an increased risk for Hereditary Nonpolyposis Colorectal Cancer (HNPCC). These criteria were further modified in 2004 and became known as the revised Bethesda Guidelines. Our study aimed to retrospectively evaluate the percentage of patients diagnosed with HNPCC tumors in 2004 who met revised Bethesda criteria for MSI testing, who were referred for genetic counseling within our institution. METHODS All HNPCC tumors diagnosed in 2004 were identified by accessing CoPath, an internal database. Both the Tumor Registry and patients' electronic medical records were accessed to collect all relevant family history information. The list of patients who met at least one of the revised Bethesda criteria, who were candidates for MSI testing, was then cross-referenced with the database of patients referred for genetic counseling within our institution. RESULTS A total of 380 HNPCC-associated tumors were diagnosed at our institution during 2004 of which 41 (10.7%) met at least one of the revised Bethesda criteria. Eight (19.5%) of these patients were referred for cancer genetic counseling of which 2 (25%) were seen by a genetics professional. Ultimately, only 4.9% of patients eligible for MSI testing in 2004 were seen for genetic counseling. CONCLUSION This retrospective study identified a number of barriers, both internal and external, which hindered the identification of individuals with HNPCC, thus limiting the ability to appropriately manage these high risk families.

Abstract
BACKGROUND Inflammatory bowel disease (IBD) is associated with increased intestinal permeability and decreased expression of tight junction (TJ) proteins in the inflamed mucosa. Whether this alteration in TJ expression is a prerequisite for the development of intestinal inflammation or a secondary result of that inflammation is unknown. This study looked at the expression of the TJ protein ZO-1 and the corresponding permeability changes in dextran sulfate sodium (DSS) induced colitis in a mouse model. MATERIALS AND METHODS BALB/c mice were fed 3% DSS or water for 1, 3, 5, or 7 days. The animals were weighed, stool was checked for blood, and the colon length measured. Segments of the colon were used for histology, immunohistochemistry for ZO-1, or Western blot for TJ proteins. Colonic permeability was measured using Evan's Blue dye. RESULTS DSS treated animals had heme positive stools, colitis by histology, significant weight loss, and colon shortening. There was an absence of ZO-1 by Western blot in the 7-day DSS treated animals, double the amount of claudin-1 and normal cytokeratin. The loss of ZO-1 started after 1 d of DSS treatment and was followed by a significant increase in permeability to Evan's blue by day 3. CONCLUSIONS The loss of ZO-1 and increased permeability preceded the development of significant intestinal inflammation suggesting that in DSS colitis alterations in the TJ complex occur before the intestinal inflammation and not as a consequence of it. These changes in the TJ complex may facilitate the development of the inflammatory infiltrate seen in colitis.

Abstract
In this study, a highly porous collagen-based biodegradable scaffold was developed as an alternative to synthetic, non-degradable corneal implants. The developed method involved lyophilization and subsequent stabilization through N-ethyl-N'-[3-dimethylaminopropyl] carbodiimide/N-hydroxy succinimide (EDC/NHS) cross-linking to yield longer lasting, porous scaffolds with a thickness similar to that of native cornea (500 microm). For collagen-based scaffolds, cross-linking is essential; however, it has direct effects on physical characteristics crucial for optimum cell behavior. Hence, the effect of cross-linking was studied by examining the influence of cross-linking on pore size distribution, bulk porosity and average pore size. After seeding the foam with human corneal keratocytes, cell proliferation, cell penetration into the scaffold and ECM production within the scaffold were studied. After a month of culture microscopical and immunohistochemical examinations showed that the foam structure did not undergo any significant loss of integrity, and the human corneal keratocytes populated the scaffold with cells migrating both longitudinally and laterally, and secreted some of the main constituents of the corneal ECM, namely collagen types I, V and VI. The foams had a layer of lower porosity (skin layer) both at the top and the bottom. Foams had an optimal porosity (93.6%), average pore size (67.7 microm), and chemistry for cell attachment and proliferation. They also had a sufficiently rapid degradation rate (73.6+/-1.1% in 4 weeks) and could be produced at a thickness close to that of the natural corneal stroma. Cells were seeded at the top surface of the foams and their numbers there was higher than the rest, basically due to the presence of the skin layer. This is considered to be an advantage when epithelial cells need to be seeded for the construction of hemi or full thickness cornea.

Abstract
Potential contamination of animal-derived collagen with pathogens has led to the demand for safe recombinant sources of this complex molecule. In continuation of our previous work [Ruggiero et al. (2000) FEBS Lett. 469, 132-136], here we show that it is possible to produce recombinant hydroxylated homotrimeric collagen in tobacco plants that are co-transformed with a human type I collagen and a chimeric proline-4-hydroxylase (P4H). This is to our knowledge the first time that transient expression in tobacco was used to improve the quality of a recombinant protein produced in plants through co-expression with an animal cell-derived modifying enzyme. We demonstrated the functionality of the new chimeric P4H and thus improved the thermal stability of recombinant collagen I from plants to 37 degrees C.

Abstract
Human unhydroxylated homotrimeric triple-helical collagen I produced in transgenic plants was used as an experimental model to provide insights into the role of hydroxyproline in molecular folding and fibril formation. By using chemically cross-linked molecules, we show here that the absence of hydroxyproline residues does not prevent correct folding of the recombinant collagen although it markedly slows down the propagation rate compared with bovine fully hydroxylated homotrimeric collagen I. Relatively slow cis-trans-isomerization in the absence of hydroxyproline likely represents the rate-limiting factor in the propagation of the unhydroxylated collagen helix. Because of the lack of hydroxylation, recombinant collagen molecules showed increased flexibility as well as a reduced melting temperature compared with native homotrimers and heterotrimers, whereas the distribution of charged amino acids was unchanged. However, unlike with bovine collagen I, the recombinant collagen did not self-assemble into banded fibrils in physiological ionic strength buffer at 20 degrees C. Striated fibrils were only obtained with low ionic strength buffer. We propose that, under physiological ionic strength conditions, the hydroxyl groups in the native molecule retain water more efficiently thus favoring correct fibril formation. The importance of hydroxyproline in collagen self-assembly suggested by others from the crystal structures of collagen model peptides is thus confirmed experimentally on the entire collagen molecule.
