Geometric control by active mechanics of epithelial gap closure

Epithelial wound healing is one of the most important biological processes occurring during the lifetime of an organism. It is a self-repair mechanism closing wounds or gaps within tissues to restore their functional integrity. In this work we derive a new diffuse interface approach for modelling the gap closure by means of a variational principle in the framework of non-equilibrium thermodynamics. We investigate the interplay between the crawling with lamellipodia protrusions and the supracellular tension exerted by the actomyosin cable on the closure dynamics. These active features are modeled as Korteweg forces into a generalised chemical potential. From an asymptotic analysis, we derive a pressure jump across the gap edge in the sharp interface limit. Moreover, the chemical potential diffuses as a Mullins-Sekerka system, and its interfacial value is given by a Gibbs-Thompson relation for its local potential driven by the curvature-dependent purse-string tension. The finite element simulations show an excellent quantitative agreement between the closure dynamics and the morphology of the edge with respect to existing biological experiments. The resulting force patterns are also in good qualitative agreement with existing traction force microscopy measurements. Our results shed light on the geometrical control of the gap closure dynamics resulting from the active forces that are chemically activated around the gap edge.

The IHI Rochester Report 2022 on Healthcare Informatics Research: Resuming After the CoViD-19

In 2020, the CoViD-19 pandemic spread worldwide in an unexpected way and suddenly modified many life issues, including social habits, social relationships, teaching modalities, and more. Such changes were also observable in many different healthcare and medical contexts. Moreover, the CoViD-19 pandemic acted as a stress test for many research endeavors, and revealed some limitations, especially in contexts where research results had an immediate impact on the social and healthcare habits of millions of people. As a result, the research community is called to perform a deep analysis of the steps already taken, and to re-think steps for the near and far future to capitalize on the lessons learned due to the pandemic. In this direction, on June 09th-11th, 2022, a group of twelve healthcare informatics researchers met in Rochester, MN, USA. This meeting was initiated by the Institute for Healthcare Informatics-IHI, and hosted by the Mayo Clinic. The goal of the meeting was to discuss and propose a research agenda for biomedical and health informatics for the next decade, in light of the changes and the lessons learned from the CoViD-19 pandemic. This article reports the main topics discussed and the conclusions reached. The intended readers of this paper, besides the biomedical and health informatics research community, are all those stakeholders in academia, industry, and government, who could benefit from the new research findings in biomedical and health informatics research. Indeed, research directions and social and policy implications are the main focus of the research agenda we propose, according to three levels: the care of individuals, the healthcare system view, and the population view.

OC-078 LAP-T LAPAROSCOPIC GAS-LESS TECHNIQUE FOR THE REPAIR OF RECTUS MUSCLES DIASTASIS AND HERNIA IN ATHLETES

Background/Aim

Diastasis of Rectus Abdominis Muscles (DRAM) in athletes is typically associated with muscle and fascial tearing and fracture and umbilical/epigastric hernias. Parietal damage is generally located on midline, subjected to continuous efforts and overload. Contrarily to repair of DRAM consequent to pregnancy or obesity, in athletes, the trigger of injury will persist after repair. LAP-T Technique aims at Mini-Invasive restoration of anatomy and physiologic functionality through laparoscopic tailored suture&mesh repair, allowing return to full sport activity.

Methods

96 cases from January 2010 to May 2021, minimum follow-up of 12 months. Elected patients: athletes, under 60 years old, BMI < 30, ASA1 – ASA2, with maximum IRD 10cm and associated AWR. Rectus muscles are re-approximated from xiphoid to pubis with tailored sutures, and hernia defect repaired, using laparoscopic running self-locking barbed sutures. Entire procedure is performed in gas-less laparoscopy (3mmHg). Considering persistence of triggering cause after repair in athletes, the repair is consolidated placing an intra-peritoneal mesh. 10–15 days from surgery, patients start following a tailored rehabilitation program up to full resumption of sport activity.

Results

In all patients, AW anatomy and physiological functionality were successfully restored, any hernia repaired, with the restitution ad integrum of the AW; no higher pain related to the continuous suturing has been reported compared to bridge IPOM laparoscopic repair, while allowing for physiologic outcome and stronger repair. No intra operative bleeding, no seroma formation, chronic pain, nor mesh infection. All athletes retrieved full sport activity at pre-hernia and DRAM level. 98% follow up at 12 months, 91% at 24, with no recurrences observed.

Conclusions

LAP-T technique proved to be feasible technique for Athletes, allowing for sound and anatomic reconstruction of DRAM, associated hernias, and musculo-fascial tearing, with reduced trauma, fast recovery and full resumption of sport activity.

The Föppl-von Kármán equations of elastic plates with initial stress

Initially, stressed plates are widely used in modern fabrication techniques, such as additive manufacturing and UV lithography, for their tunable morphology by application of external stimuli. In this work, we propose a formal asymptotic derivation of the Föppl-von Kármán equations for an elastic plate with initial stresses, using the constitutive theory of nonlinear elastic solids with initial stresses under the assumptions of incompressibility and material isotropy. Compared to existing works, our approach allows us to determine the morphological transitions of the elastic plate without prescribing the underlying target metric of the unstressed state of the elastic body. We explicitly solve the derived FvK equations in some physical problems of engineering interest, discussing how the initial stress distribution drives the emergence of spontaneous curvatures within the deformed plate. The proposed mathematical framework can be used to tailor shape on demand, with applications in several engineering fields ranging from soft robotics to four-dimensional printing.

O52 LAP-T MINI LAPAROSCOPIC TECHNIQUE FOR THE REPAIR OF RECURRENT UMBILICAL HERNIA ON PRIMARILY UNTREATED DIASTASIS

Aim

“This retrospective analysis on 1000 cases of Diatasis Recti (DR) complicated by single/multiple, primary/recurrent hernias, all treated with the Laparoscopic Abdominoplasty Technique (LAP-T), aims at evaluating the possible correlation of higher recurrence rate and complications when DR is left untreated”

Material and Methods

“This review on 1000 patients, <65yrs, BMI<30, 3>IRD>12, based on CT Scan/MRI study, showed 235 (23,5%) of them to be recurrent umbilical/midline hernias engaged on untreated RMD, independently from the surgical technique used for primary repair. Re-operation with LAP-T technique, consisted in removal of recurrent hernia and dislocated mesh when present, closure by self-locking running sutures of the hernia defect and the DR. Repair is consolidated placing an intra-peritoneal mesh”

Results

“In all patients, recurrence was repaired, DR reconstructed and abdominal wall anatomy and physiological functionality successfully restored. No intra operative bleeding, seroma formation, chronic pain, nor mesh infection have been recorded. 98% follow up at 12 months, 91% at 24, no recurrences observed”

Conclusions

“Higher incidence of recurrent umbilical/midline hernias observed in this analysis, compared to average recurrence rate reported in literature, suggest that regardless primary repair technique, the repair of the sole hernia engaged on a DR is likely to lead to a recurrent hernia, further midline hernia defects formation and worsening of the DR. A significant correlation between the recurrency after primary umbilical/midline repair when a concomitant RMD is left untreated is likely to lead to a more invasive and complicated re-intervention, higher complication rate and discomfort for the patient”

Clinical Information Systems and Artificial Intelligence: Recent Research Trends

OBJECTIVES

This survey aims at reviewing the literature related to Clinical Information Systems (CIS), Hospital Information Systems (HIS), Electronic Health Record (EHR) systems, and how collected data can be analyzed by Artificial Intelligence (AI) techniques.

METHODS

We selected the major journals (11 journals) collecting papers (more than 7,000) over the last five years from the top members of the research community, and read and analyzed the papers (more than 200) covering the topics. Then, we completed the analysis using search engines to also include papers from major conferences over the same five years.

RESULTS

We defined a taxonomy of major features and research areas of CIS, HIS, EHR systems. We also defined a taxonomy for the use of Artificial Intelligence (AI) techniques on healthcare data. In the light of these taxonomies, we report on the most relevant papers from the literature.

CONCLUSIONS

We highlighted some major research directions and issues which seem to be promising and to need further investigations over a medium- or long-term period.

DEDICATE: proposal for a conceptual framework to develop dementia-friendly integrated eCare support

Background

Evidence shows that the implementation of information and communication technologies (ICT) enabled services supporting integrated dementia care represents an opportunity that faces multi-pronged challenges. First, the provision of dementia support is fragmented and often inappropriate. Second, available ICT solutions in this field do not address the full spectrum of support needs arising across an individual’s whole dementia journey. Current solutions fail to harness the potential of available validated e-health services, such as telehealth and telecare, for the purposes of dementia care. Third, there is a lack of understanding of how viable business models in this field can operate. The field comprises both professional and non-professional players that interact and have roles to play in ensuring that useful technologies are developed, implemented and used.

Methods

Starting from a literature review, including relevant pilot projects for ICT-based dementia care, we define the major requirements of a system able to overcome the limitations evidenced in the literature, and how this system should be integrated in the socio-technical ecosystem characterizing this disease. From here, we define the DEDICATE architecture of such a system, and the conceptual framework mapping the architecture over the requirements.

Results

We identified three macro-requirements, namely the need to overcome: deficient technology innovation, deficient service process innovation, and deficient business models innovation. The proposed architecture is a three level architecture in which the center (data layer) includes patients’ and informal caregivers’ preferences, memories, and other personal data relevant to sustain the dementia journey, is connected through a middleware (service layer), which guarantees core IT services and integration, to dedicated applications (application layer) to sustain dementia care (formal support services, FSS), and to existing formal care infrastructures, in order to guarantee care coordination (care coordination services, CCS).

Conclusions

The proposed DEDICATE architecture and framework envisages a feasible means to overcome the present barriers by: (1) developing and integrating technologies that can follow the patient and the caregivers throughout the development of the condition, since the early stages in which the patient is able to build up preferences and memories will be used in the later stages to maximise personalization and thereby improve efficacy and usability (technology innovation); (2) guaranteeing the care coordination between formal and informal caregivers, and giving an active yet supported role to the latter (service innovation); and (3) integrating existing infrastructures and care models to decrease the cost of the overall care pathway, by improving system interoperability (business model innovation).

Leukocyte Tracking Database, a collection of immune cell tracks from intravital 2-photon microscopy videos

Recent advances in intravital video microscopy have allowed the visualization of leukocyte behavior in vivo, revealing unprecedented spatiotemporal dynamics of immune cell interaction. However, state-of-the-art software and methods for automatically measuring cell migration exhibit limitations in tracking the position of leukocytes over time. Challenges arise both from the complex migration patterns of these cells and from the experimental artifacts introduced during image acquisition. Additionally, the development of novel tracking tools is hampered by the lack of a sound ground truth for algorithm validation and benchmarking. Therefore, the objective of this work was to create a database, namely LTDB, with a significant number of manually tracked leukocytes. Broad experimental conditions, sites of imaging, types of immune cells and challenging case studies were included to foster the development of robust computer vision techniques for imaging-based immunological research. Lastly, LTDB represents a step towards the unravelling of biological mechanisms by video data mining in systems biology.

Researches about Knowledge of Self-Examination and some Problems about Breast Cancer

A research on the degree of knowledge about the problem of breast self-examination was carried out in a group of 500 women in the Out-patients Department of the Cancer Institute in Milan.

The women were given a questionnaire to fill up at home and to return at the moment of the medical examination.

The analysis of data showed that, though the level of education of the subjects was fairly good, the knowledge and the practise of the periodical self-examination as a method for an early diagnosis was very low. 70% of the women declared to have some knowledge about the method, but only 9% declared to practise it regularly.

Managing Different Time Granularities of Clinical Information by an Interval-based Temporal Data Model

In the field of databases, time management at different levels of granularity has been an issue for several years, for instance when dealing with clinical information from different databases using different time units, dealing with natural language expressions, or when dealing with temporal uncertainty. A temporal data model is proposed to manage the temporal aspect of data, presented at various and mixed levels of granularity. The concept of temporal assertions shapes the entire temporal information. The model provides a temporal dimension to the data by using intervals that can be specified at different granularities. The model supports a three-valued logic, where True, False and Undefined are the truth values. The temporal data model allows to manage some degrees of uncertainty when establishing temporal relationships between intervals or between temporal assertions, expressed at different granularities. The logical connectives and quantifiers can manage each of the three truth-values.

We applied the temporal data model by implementing an object-oriented database system for managing follow-up clinical data from patients who underwent percutaneous transluminal coronary angioplasty.

MS2/Cardio: Towards a Multi-Service Medical Software for Cardiology

Many clinics are interested to use software packages in daily practice, but lack of integration of such packages seriously limits their scope. In practice this often entails switching between programs and interrupting the run of an individual program. A multi-task approach would not solve this problem as it would not eliminate the need to input the same data many times, as often occurs when using separate packages. The construction of a Multi-Service Medical Software package (MSx2) is described, which was also developed as an example of practical integration of some clinically relevant functions. The package runs on a personal computer in an MS-DOS environment and integrates a time-oriented medical record management unit (TOMRU) for data of ambulatory patients, and a drug information management unit (DIMU) concerning posology, content, effects, and possible interactions. Of the possible database configurations allowed by MSx2, the cardiology patient database (MSx2/C) and hypertensive patient database (MSx2/H) were developed and described here. Clinical information to be included in the configurations was obtained after discussion and consensus of clinical practitioners. MSx2/C was distributed to several hundred clinical centers during computerized courses to train future users. MSx2 can easily transfer patient data to statistical processing packages.

Correlations between medical students’ specialty choice and different attitudes towards mental illness

Introduction

Discrimination and stigmatization cause an important burden for people suffering from psychiatric disorders. The medical doctors, those who should be important reference points for psychiatric patients, are instead one of the categories that contribute to their stigmatization.

Objectives

It is extremely important to study and to know the attitudes of undergraduate medical students towards psychiatric disorders, since these individuals will be involved in the care of these patients throughout their careers.

Aims

The present study analyzes the attitudes of a group of Italian medical students towards mental illness, highlighting the differences between the students who would choose surgical specialties from those who prefer medical ones.

Methods

A total of 339 medical students of different medical schools, in Rome and Foggia (Italy), completed a cross-sectional survey. The Italian version of community attitude towards the mentally Ill test (CAMI) was used to evaluate the students’ attitudes.

Results

The students that would choose medical specialties reported less stigmatizing responses in 11 CAMI items (including five items with P < 0.01), in benevolence and community mental health ideology subscales (P = 0.003) and in the total score (P = 0.003).

Conclusions

It is evident that the students that prefer the surgical specialties have more stigmatizing attitudes towards psychiatric patients. Negative feedbacks on Psychiatry from non-psychiatrist colleagues may have a fundamental role in stigmatizing mental disorders.

Differences in empathy in Italian university students: Are medical students more or less empathetic?

Introduction

Empathy is the capacity to understand or feel what another person is experiencing. It is an important quality in the medical profession, since it is fundamental in interpersonal relationships with patients. Nevertheless, many studies have found that over time medical students (MS) become less empathic and more detached from patients.

Objectives and aims

To determine MS loss of empathy and to study the differences in empathy between MS and other university students who are not involved in healthcare.

Methods

We enrolled 244 MS (120 of the 1st year and 124 of the last year) and 125 other university students not involved in healthcare, in different universities in Rome and Foggia (Italy). They anonymously and voluntarily completed a socio-demographic questionnaire and Baron Cohen's empathy quotient test (EQ).

Results

We found no differences regarding EQ total score between MS and other students, however there are few differences considering individual EQ items. In particular, MS really like taking care of others (P = 0.005) and they are sometimes considered to be rude, even if only they are only blunt (P = 0.006). We found no differences in empathy between first year and last year MS.

Conclusions

In our sample of Italian students, we have not found MS to be more or less empathetic than other university students, but there are some peculiar differences in empathy that make them better suited to the chosen course of study. Moreover, we found no differences between the different years of medical school.

Adherence to Selective Serotonin and Serotonin-Norepinephrine Reuptake Inhibitor Prescriptions Affects Overall Medication Adherence in Older Persons: Evidence From the Italian Nationwide OsMed Health-DB Database

OBJECTIVE

This study aimed to evaluate prevalence of prescription of and adherence to selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs) and whether adherence to these classes of drugs affects overall medication adherence in older persons.

METHODS

In a cross-sectional analysis of administrative data comprehensive of all prescribed drugs reimbursed by the Italian national health care system, new prescriptions of SSRIs and SNRIs to persons aged 65 years or older were analyzed (n = 380,400 in 2011; 395,806 in 2012; 409,741 in 2013, from a total sample of 3,762,299 persons aged 65 years or older) as well as prescriptions of antihypertensives, statins, other psychiatric drugs, antidiabetics, antiplatelets, anticoagulants, drugs for chronic obstructive pulmonary disease, and antiosteoporotics. Adherence was estimated by calculating the proportion of days covered by drugs dispensed during a period of 365 days. Adherence was defined as a proportion of days covered of more than 80%.

RESULTS

Prevalence of SSRI and SNRI prescriptions varied from 11.4% in 2011 to 12.1% in 2013. Adherence to SSRI and SNRI prescriptions ranged from 31.2% in persons aged ≥ 95 years in 2011 to 41.8% in persons aged 75-84 years in 2013. Persons adherent to SSRI and SNRI prescriptions were more likely to be adherent to the other medications, after adjustment for age, gender, and number of drugs prescribed. The highest association was found for adherence to psychiatric drugs (OR = 1.9; 95% CI, 1.8-2.0).

CONCLUSIONS

Adherence to SSRI and SNRI prescriptions is poor in older persons. However, people adherent to these classes of antidepressants are more likely to be adherent to the other medications they are prescribed. Studies are needed to evaluate the reasons for and the potential benefits of increasing adherence to antidepressants on overall adherence.

Telemedicine for Developing Countries. A Survey and Some Design Issues

BACKGROUND

Developing countries need telemedicine applications that help in many situations, when physicians are a small number with respect to the population, when specialized physicians are not available, when patients and physicians in rural villages need assistance in the delivery of health care. Moreover, the requirements of telemedicine applications for developing countries are somewhat more demanding than for developed countries. Indeed, further social, organizational, and technical aspects need to be considered for successful telemedicine applications in developing countries.

OBJECTIVE

We consider all the major projects in telemedicine, devoted to developing countries, as described by the proper scientific literature. On the basis of such literature, we want to define a specific taxonomy that allows a proper classification and a fast overview of telemedicine projects in developing countries. Moreover, by considering both the literature and some recent direct experiences, we want to complete such overview by discussing some design issues to be taken into consideration when developing telemedicine software systems.

METHODS

We considered and reviewed the major conferences and journals in depth, and looked for reports on the telemedicine projects.

RESULTS

We provide the reader with a survey of the main projects and systems, from which we derived a taxonomy of features of telemedicine systems for developing countries. We also propose and discuss some classification criteria for design issues, based on the lessons learned in this research area.

CONCLUSIONS

We highlight some challenges and recommendations to be considered when designing a telemedicine system for developing countries.

Advanced Age and Medication Prescription: More Years, Less Medications? A Nationwide Report From the Italian Medicines Agency

BACKGROUND

In older adults co-occurrence of multiple diseases often leads to use of multiple medications (polypharmacy). The aim of the present study is to describe how prescription of medications varies across age groups, with specific focus on the oldest old.

METHODS

We performed a cross-sectional study using 2013 data from the OsMed Health-DB database (mean number of medicines and defined daily doses prescribed in 15,931,642 individuals). There were 3,378,725 individuals age 65 years or older (21.2% of the study sample).

RESULTS

The mean number of prescribed medications progressively rose from 1.9 in the age group <65 years to 7.4 in the age group 80-84 years and then declined, with a more marked reduction in the age group 95 years or older with a mean number of 2.8 medications. A similar pattern was observed for the mean number of defined daily doses. Among participants age ≥65 years, proton pump inhibitors were the most commonly prescribed medication (40.9% of individuals ≥65 years), followed by platelet aggregation inhibitors (32.8%) and hydroxy-methylglutaryl-coenzyme A reductase inhibitors (26.1%). A decline in prescription was observed among individuals age 90 years or older, but this reduction was less consistent for medications used to treat acute conditions (ie, antibiotics and glucocorticoids) rather than preventive medicines commonly used to treat chronic diseases (ie, antihypertensive medications and hydroxy-methylglutaryl-coenzyme A reductase inhibitors).

CONCLUSIONS

The burden of medication treatment progressively increases till age 85 and substantially declines after age of 90 years. Patterns of medication prescription widely vary across age groups.

A Design Methodology for Medical Processes

BACKGROUND

Healthcare processes, especially those belonging to the clinical domain, are acknowledged as complex and characterized by the dynamic nature of the diagnosis, the variability of the decisions made by experts driven by their experiences, the local constraints, the patient's needs, the uncertainty of the patient's response, and the indeterminacy of patient's compliance to treatment. Also, the multiple actors involved in patient's care need clear and transparent communication to ensure care coordination.

OBJECTIVES

In this paper, we propose a methodology to model healthcare processes in order to break out complexity and provide transparency.

METHODS

The model is grounded on a set of requirements that make the healthcare domain unique with respect to other knowledge domains. The modeling methodology is based on three main phases: the study of the environmental context, the conceptual modeling, and the logical modeling.

RESULTS

The proposed methodology was validated by applying it to the case study of the rehabilitation process of stroke patients in the specific setting of a specialized rehabilitation center. The resulting model was used to define the specifications of a software artifact for the digital administration and collection of assessment tests that was also implemented.

CONCLUSIONS

Despite being only an example, our case study showed the ability of process modeling to answer the actual needs in healthcare practices. Independently from the medical domain in which the modeling effort is done, the proposed methodology is useful to create high-quality models, and to detect and take into account relevant and tricky situations that can occur during process execution.

Differences in attitudes towards mental illness and psychiatry among medical students, before and after the academic course of psychiatry

Background

Stigma towards mental illness and psychiatry have a major impact on psychiatric patients’ quality of life; in particular, prejudicial beliefs make it more difficult for future doctors to send patients to mental health services, leading to a delay of necessary care.

Aims

Our aim is to evaluate the stigma towards mental illness and psychiatry, in a sample of Italian medical students. We studied the differences between the first-year students who have not attended the academic course in psychiatry, compared to the senior students who have attended the psychiatric lectures.

Methods

We tested 113 medical students, using the following questionnaires:

– Attitudes Towards Psychiatry (ATP 30);

– Community Attitudes Towards Mental Ill (CAMI);

– Perceived Discrimination Devaluation Scale (PDD), to assess the discrimination towards mental illness perceived in society;

– Baron-Cohen's Empathy Quotient (EQ), to measure empathy.

Results

Among the 113 students, 46 have already attended the academic course of psychiatry and CAMI scores were less stigmatizing as total score (P = 0.014) and in authoritarianism subscale (P = 0.049), social restriction (P = 0.022) and ideology of mental health in the community (P = 0.017). However, there were no statistically significant differences in empathy, perceived discrimination in the society and stigmatization of psychiatry.

Conclusions

The 67 students who have not attended the academic course of psychiatry are more stigmatizing, considering psychiatric patients as inferior people that require coercive attitudes, socially dangerous and that should be treated faraway from the community. Studying psychiatry is therefore useful to reduce, in the future doctors, these prejudices toward mentally ill patients.

Mental Health and Empathy: Do Nursing Students Have Better Attitudes to Psychiatric Patients?

Background

Stigma towards mental illness has a major impact on the quality of life and the health care of psychiatric patients. Several studies have reported that health professionals have more negative attitudes than general population.

Aims

To explore empathy and attitudes towards mental illness in nursing students (NS) and non-health university students. Our purpose is to see how NS have more empathic and less stigmatizing attitudes towards psychiatric patients, compared to other university students.

Methods

We tested 96 university students (50 NS and 46 non-health university students), with the following questionnaires anonymously filled out:

– Community attitudes towards mental ill (CAMI), to evaluate the different students’ attitudes towards mental illness;

– Empathy quotient (EQ), to assess empathy.

Results

NS differs from the other group in 5 items of CAMI (P < 0.05 in 3 items and P < 0.01 in 2 items), and Authoritarianism subscale (P = 0.023). This shows that NS have a greater general awareness and less stigmatizing attitudes about the need to hospitalize the mentally ill, the difference between psychiatric patients and general population, the wrong need of segregation and the real causes of mental illness. There is also a significant difference in EQ (items 6, 21, 25, 44, 59): future nurses seem to have a slightly higher empathy, even though the EQ total score does not differ in the two groups.

Conclusions

These results suggest that there is a difference with respect to the attitudes towards psychiatric patients in NS and students who do not follow health-care courses: NS have more empathetic and less stigmatizing attitudes.

Different Attitudes Toward Psychiatry and Psychiatric Patients in Nursing Students: Can Personal Experiences Reduce Stigma?

Background

Psychiatric patients often do not receive the same health treatment reserved for patients with no mental disorders. Stigma in mental-health nurses can worsen the patients’ healing time and quality of care.

Objective

To explore the different attitudes towards mental illness and psychiatry in nursing students (NS) of the first and the final year of university, and the importance of having visited a psychiatric ward and having known a psychiatric patient.

Methods

Fifty NS completed the following tests:

– Community attitudes towards mental ill (CAMI);

– Attitudes towards psychiatry (ATP-30);

– Empathy quotient (EQ).

Results

NS of the final year differ significantly from those of the first year in 4 CAMI items, in Authoritarianism subscale (P = 0.041), Social Restrictiveness (P = 0.029) and Community Mental Health Ideology (P = 0.045), indicating a more mature and responsible approach to psychiatric patients, without considering them a threat to be secluded. EQ does not show a significant difference in empathy, not even considering the individual items. Final year NS also have more positive attitudes toward Psychiatry in 3 ATP-30 items and total score (P = 0.01). Those who visited a psychiatric ward have more positive attitudes towards mental illness and Psychiatry, in 6 CAMI items and 3 ATP-30 items. Having personally known a psychiatric patient leads to positive attitudes in only a few CAMI items.

Conclusions

Last-year NS, who have had more direct relationships with patients through practical training, have more empathetic and less stigmatizing attitudes. It is also very useful to attend a psychiatric ward during the nursing training.

Attitudes toward psychiatry and psychiatric patients in medical students: Can real-world experiences reduce stigma?

Introduction

Stigma towards psychiatry and mental illness significantly worsens the quality of life of psychiatric patients. Negative prejudices in medical students make it difficult for future doctors to send patients to mental health services and promote an increased risk of premature death.

Aims

Our aim is to assess stigma towards mental illness and psychiatry in medical students, and to study the influence of real-world experiences, such as having visited a psychiatric ward, having personally met a psychiatric patient or having friends and/or family members who suffer from a mental illness.

Methods

One hundred and thirteen Italian medical students completed the following tests:

– Attitudes Towards Psychiatry (ATP-30);

– Community Attitudes Towards Mental Ill (CAMI);

– Perceived Discrimination Devaluation Scale (PDD);

– Baron-Cohen's Empathy Quotient (EQ).

Results

Having visited a psychiatric ward correlates with a better attitude towards psychiatry (P = 0.008), rather than towards the mentally ill. Having personally known someone with mental disorders correlates with less stigmatizing scores in CAMI: total score (P = 0.002), authoritarianism (P < 0.001), benevolence (P = 0.047) and social restriction (P = 0.001). Similar results emerged in those who have close relationships with a psychiatric patient. There is no statistical significance as to empathy.

Conclusions

The students who have visited a psychiatric ward have a less stigmatizing vision of psychiatry, while having personally known psychiatric patients favors a less stigmatizing attitude towards them. Those who have not had this experience, have a more hostile and intolerant vision of mental illness, and consider psychiatric patients as inferior subjects that require coercive attitudes and that would be better to avoid because socially dangerous.

Domains of Health IT and Tailoring of Evaluation: Practicing Process Modeling for Multi-Stakeholder Benefits

This contribution focuses on the heterogeneity and complexity of health information technology services and systems in a multi-stakeholder environment. We propose the perspective of process modeling as a method to break out complexity, represent heterogeneity, and provide tailored evaluation and optimization of health IT systems and services. Two case studies are presented to show how process modeling is needed to fully understand the information flow, thus identifying requirements and specifications for information system re-engineering and interoperability; detect process weaknesses thus designing corrective measures; define metrics as a mean to evaluate and ensure system quality; and optimize the use of resources.

Working conditions and mental health in teachers: a preliminary study

BACKGROUND

Unfavourable working conditions are associated with poor mental health and many studies show that teachers are at risk of this.

AIMS

To investigate if and to what extent specific dimensions of working conditions are associated with symptoms of depression and anxiety in teachers in state schools in Italy.

METHODS

A cross-sectional questionnaire survey of Italian state schoolteachers using the Karasek Job Content Questionnaire, the Self-Rating Anxiety Scale (SAS) and the Center for Epidemiologic Studies Depression Scale (CES-D). We tested the hypotheses that high job demand, low decision latitude and low support are associated with anxiety and depression in teachers using a correlation matrix and hierarchical multiple regression models.

RESULTS

113/180 (63%) of schoolteachers invited to participate completed the survey. 49% scored above the cut-off on CES-D and 11% on SAS. CES-D was positively correlated with job demand (r = 0.517, P < 0.01) and negatively with social support (r = -0.226, P < 0.05). SAS was positively correlated with job demand (r = 0.408, P < 0.01). Hierarchical multiple regression analysis showed that job demand was significantly associated with CES-D and SAS scores, explaining 28 and 25% of variance respectively.

CONCLUSIONS

About half of the teachers in this study scored above the threshold for depression and ~1 in 10 for anxiety on self-rating questionnaires. Poor mental health in teachers is significantly associated with high job demand and low social support. These results should be confirmed in larger, more representative samples.

Counting elementary charges on nanoparticles by electron holography

The distribution and movement of charge is fundamental to many physical phenomena, particularly for applications involving nanoparticles, nanostructures, and electronic devices. However, there are very few ways of quantifying charge at the necessary length scale. Here, we show that aberration-corrected electron holography is capable of counting the charge on individual nanoparticles to a precision of one elementary unit of charge. We present a method that measures charges within predefined contours by directly applying Gauss's law at the nanoscale. We perform a statistical analysis to reveal the relationship between the size of the contours and the precision of the charge measurement and present strategies to optimize the spatial and signal resolution for the presented method.

Aripiprazole, alcohol and substance abuse: a review

Aripiprazole is an atypical antipsychotic used for schizophrenia, manic and mixed episodes associated with bipolar I disorder and as adjunctive therapy for major depressive disorder. It functions as a partial agonist at dopamine D2 and 5-HT1A receptors, and as an antagonist at the 5-HT2A receptor. The most recent results obtained from scientific research showed that dopaminergic mechanisms are involved in motivation, reward, and reinforcement of substance abuse. The use of aripiprazole and partial dopamine agonists could represent a novel strategy for normalizing dopamine neurotransmission. Many studies in the last few years have highlighted aripiprazole as a potential candidate for the treatment of different types of substance dependence. This review aims to describe recent scientific research using aripiprazole in different substance abuse disorders (i.e., alcoholism, cocaine, amphetamine and nicotine use). Furthermore, the efficacy of aripiprazole compared to other pharmacological therapies will be described. Given the low number of studies, the frequent absence of placebo or active comparators, and the low statistical power of the studies, a clear conclusion about the use of aripiprazole in alcohol/substance dependence cannot be drawn. Therefore, we suggest the need for further studies, preferably randomized and placebo-controlled.

"Fast track surgery" in the north-west of Italy: influence on the orientation of surgical practice

Fast track surgery is a peri-operative management model, including different strategies to improve patients' convalescence, avoid metabolic alterations, reduce complications, and shorten hospital stay. Prerequisite is coordination between different practitioners (surgeon, anaesthetist, nurse, nutritionist, physiotherapist). The purpose of our investigation is to understand the level of fast track surgery application in Piedmont and to evidence analogies and differences among departments. We projected an investigation proposing, to every surgery department in Piedmont, a multiple-choice questionnaire evaluating the level of fast track surgery peri-operative interventions' application. Data analysis was conducted in two points of view: the transversal one with an overview of answer's percentages, the longitudinal one correlating data through Pearson's index (r). We collected answers by 78 % of balloted departments (38 on 49). Transversal analysis, including the evaluation of percentages of each question, shows that intra-operative period is the most influenced by fast track principles, and that only 12 departments of 38 apply complete protocols. Longitudinal analysis, estimating the whole of each department's answers, demonstrates the absence of statistical significance in the correlation between fast track surgery application and territorial (r = 0.18), economic (r = 0.31), or age (r = 0.06) variables. Influence of fast track surgery is significantly present in our territory, even though it is not fully concretized in protocols. The choice of fast track depends on the instruction, the environment and the sensibility of each surgeon. Knowledge of geographic distribution of departments applying this model can be useful to organize common protocols, starting from more experienced hospitals.

Querying temporal clinical databases on granular trends

This paper focuses on the identification of temporal trends involving different granularities in clinical databases, where data are temporal in nature: for example, while follow-up visit data are usually stored at the granularity of working days, queries on these data could require to consider trends either at the granularity of months ("find patients who had an increase of systolic blood pressure within a single month") or at the granularity of weeks ("find patients who had steady states of diastolic blood pressure for more than 3 weeks"). Representing and reasoning properly on temporal clinical data at different granularities are important both to guarantee the efficacy and the quality of care processes and to detect emergency situations. Temporal sequences of data acquired during a care process provide a significant source of information not only to search for a particular value or an event at a specific time, but also to detect some clinically-relevant patterns for temporal data. We propose a general framework for the description and management of temporal trends by considering specific temporal features with respect to the chosen time granularity. Temporal aspects of data are considered within temporal relational databases, first formally by using a temporal extension of the relational calculus, and then by showing how to map these relational expressions to plain SQL queries. Throughout the paper we consider the clinical domain of hemodialysis, where several parameters are periodically sampled during every session.

Depression, inflammation and coronary heart disease: prognostical value of c reactive protein and depressive symptoms

Introduction

The aim of this preliminary study is to assess, in a sample of patients with Coronary Heart Disease (CHD), the specific association between depressive symptoms and systemic inflammation.

Methods

Sixty-One inpatients with CHD, 31 Unstable Angina and 28 Myocardial Infarction, participated in the study. The plasma levels of C Reactive Protein were measured using Dade Behring’s High Sensitivity CRP assay (hs-CRP) at T0, T30 and T90.

At the same timings, they were tested by an examiner, unaware of their diagnosis, with a psychometric battery (SCL90-R, HDRS, MADRS, BDI, QlesQ).

Results

The elevation of hs-CRP occurs during the whole observation period, with maximum significance at T90 (p = 0,031).

A multivariate analysis at T0 indicates a statistical correlation between SCL90-R scores and hs-CRP levels (p = 0.02).

The SCL90-R is also associated with the risk of further cardiac events (p = 0.013).

Also the BDI could be useful as a prognostic factor (p = 0.026).

We found a trend towards correlation between CRP values and depressive symptoms, but it never reaches statistical significance for the other scales.

Conclusions

The feelings of loss and the fear of death, related to the environmental and emotional situation of the hospitalization, may prevail in the acute phase of CHDs.

Some patients may overcome this reactive depression, while others may exhibit a biological depression, related to the high level of CRP and thus to an increased risk of re-infarction and other coronary events.

[Diagnosis of deficit and attention/hyperactivity disorders (ADHD) in patients with bipolar or unipolar depression: an experimental study]

INTRODUCTION

The present research study starts up from the current scientific and academic interest concerning Deficit and Attention/Hyperactivity Disorders, which in this period seems to have an "epidemic" diffusion. Some authors have proved how the Deficit and Attention/Hyperactivity Disorder may predispose to the development of other psychopathological attitude in adulthood. A recent study has underlined a common comorbidity between ADHD in childhood and Bipolar Disorder. The aim of the present was to verify the existence of an ADHD diagnosis in patients with depression (Unipolar and Bipolar) and to verify if such syndrome overstays in the present psychopathological picture. Moreover there has been even the intention to investigate on a difference in ADHD symptomatology in patients with Bipolar and Unipolar Depression.

MATERIALS AND METHODS

The study has been conducted on a sample of 67 patients with depression diagnosis (35 patients with bipolar depression diagnosis, 32 patients with depression unipolar diagnosis) enrolled at the Bipolar Disorders Unit of the Clinical Psychiatry and Drug Dependence Institute of the Policlinico Universitario A. Gemelli in Rome. The evaluation has been performed through the supply of the following psychometric tests: Neo Personality Inventory (Mole-pi-R), Brown Attention Deficit Disorder Scale (Brown ADD-Scale), Adult ADHD Self-Report Staircases (ASRS-v1.1), Criteria of the Deficit and Attention / Hyperactivity Disorder for childhood according to the DSM-IV-Tr.

RESULTS

The achieved results point out that 42% of the sample has satisfied the ADHD Criterions during their childhood according to the DSM-IV-Tr and that symptomatology seems to remain in the present psychopathological picture. As to polarity of depression it has emerged that patients with Bipolar Depression diagnosis have satisfied with a greater frequency the ADHD criteria during their childhood than patients with Unipolar Depression.

CONCLUSIONS

Our results seem to confirm the hypothesis that patients with bipolar depression diagnosis have more Deficit and Attention / Hyperactivity Disorders comorbidity diagnosis than others.
