Utilization of big data to improve management of the emergency departments. Results of a systematic review

Background. The emphasis on using big data is growing exponentially in several sectors including biomedicine, life sciences and scientific research, mainly due to advances in information technologies and data analysis techniques. Actually, medical sciences can rely on a large amount of biomedical information and Big Data can aggregate information around multiple scales, from the DNA to the ecosystems. Given these premises, we wondered if big data could be useful to analyze complex systems such as the Emergency Departments (EDs) to improve their management and eventually patient outcomes. Methods. We performed a systematic review of the literature to identify the studies that implemented the application of big data in EDs and to describe what have already been done and what are the expectations, issues and challenges in this field. Results. Globally, eight studies met our inclusion criteria concerning three main activities: the management of ED visits, the ED process and activities and, finally, the prediction of the outcome of ED patients. Although the results of the studies show good perspectives regarding the use of big data in the management of emergency departments, there are still some issues that make their use still difficult. Most of the predictive models and algorithms have been applied only in retrospective studies, not considering the challenge and the costs of a real-time use of big data. Only few studies highlight the possible usefulness of the large volume of clinical data stored into electronic health records to generate evidence in real time. Conclusion. The proper use of big data in this field still requires a better management information flow to allow real-time application

ER access by foreign citizens between 1999 and 2014 in five large hospital of Rome, Italy

...Lack of information about the health services and the status of illegal immigrant can make difficult for foreign population to access primary care, leading to misuse of emergency rooms (ER). This study investigated the accesses between January 1999 and December 2014 to the ERs of five large hospital of Rome, Italy

Heart Rate Variability from Wearable Photoplethysmography Systems: Implications in Sleep Studies at High Altitude

The interest in photoplethysmography (PPG) for sleep monitoring is increasing because PPG may allow assessing heart rate variability (HRV), which is particularly important in breathing disorders. Thus, we aimed to evaluate how PPG wearable systems measure HRV during sleep at high altitudes, where hypobaric hypoxia induces respiratory disturbances. We considered PPG and electrocardiographic recordings in 21 volunteers sleeping at 4554 m a.s.l. (as a model of sleep breathing disorder), and five alpine guides sleeping at sea level, 6000 m and 6800 m a.s.l. Power spectra, multiscale entropy, and self-similarity were calculated for PPG tachograms and electrocardiography R-R intervals (RRI). Results demonstrated that wearable PPG devices provide HRV measures even at extremely high altitudes. However, the comparison between PPG tachograms and RRI showed discrepancies in the faster spectral components and at the shorter scales of self-similarity and entropy. Furthermore, the changes in sleep HRV from sea level to extremely high altitudes quantified by RRI and PPG tachograms in the five alpine guides tended to be different at the faster frequencies and shorter scales. Discrepancies may be explained by modulations of pulse wave velocity and should be considered to interpret correctly autonomic alterations during sleep from HRV analysis

Low level of attention to health inequalities in prevention planning activities of the Italian Regions

Background: Health promotion and prevention activities should tackle health inequalities to reduce disparities in health among disadvantaged populations. This study aimed to assess the extent to which the Italian Regions considered health inequalities during the planning of prevention activities, to detect geographical differences and to identify the possible determinants of differences in attention to health inequalities. Methods: The 19 Regional Prevention Plans (RPPs) developed by Italian Regions within the National Prevention Plan (NPP) 2010-2013 were assessed using a specific tool to address the level of attention to health inequalities. Univariate and multivariate analyses were performed to identify regional characteristics associated with a higher level of attention to health inequalities. Results: Of the 702 projects included in the 19 RPPs, only 56 (8.0 %) specifically addressed issues related to health inequalities. The results of the multivariate analysis showed that a higher level of attention was associated with the macroarea of intervention 'prevention in high-risk groups', with the higher quality of the Strategic Plan Section of the RPP and with the higher percentage of migrants in the Region in 2010. Moreover, projects that addressed the topic of health inequalities were more likely to be developed in the Northern Regions, in Regions with a lower level of 'linking social capital' and with a Higher Regional Health Care Expenditure (RHCE) as a percentage of Regional Gross Domestic Product (RGDP) in 2010. Conclusions: The level of attention to health inequalities in the regional planning process of prevention activities 2010-2013 in Italy is low. The results of this study supported the new round of prevention planning in Italy, and highlight the urgent need to increase the number of policies and interventions able to reduce health inequalities

European survey on knowledge and attitudes of public health professionals on public health genomics: pilot study

Background: During the past decade a debate has arisen on the possible utility of genomic science for public health purposes. Within this context, a survey is being conducted to assess attitudes of European public health (PH) professionals belonging to European Public Health Association (EUPHA) network regarding their role in the implementation of public health genomics (PHG), and their knowledge and attitudes regarding genetic testing and the delivery of genetic services. Methods: A pilot on-line survey was conducted on professionals from Sapienza University of Rome and the Vrije University of Amsterdam. The survey tool is composed of 5 sections: Personal details, Professional activity, Knowledge on genetic testing and delivery of genetic services, Attitudes on genetic testing and delivery of genetic services, Attitudes on the role of PH professionals in PHG. Results: 34 people responded to the questionnaire, mostly medical doctors (61.8%). No respondents correctly identified all evidence-based applications of genetic testing. More than one third of respondents agreed that it would be more important to invest resources in the social and environmental causes of ill health than in genetic testing. Nearly 70% thought that PHG needs to be grounded on evidence of effectiveness, a lower rate agreed ii should be grounded on cost-effectiveness. The rate of agreement with the proposed roles of PH professionals in PHG was very high. Conclusion: This pilot study showed a positive attitude but the need to improve knowledge of PH professionals on PHG. It provided useful input for the implementation of the survey to all members of the EUPHA network

Surgery for Complex forms of Atrioventricular Septal Defect: Early Survival and Probability of Cure

Atrioventricular Septal Defects (AVSD) account for 7.4% of Congenital Heart Defects (CHD). They may occur in isolation, with a narrow spectrum of age at presentation and prognosis, or in association with other intracardiac malformations: here symptoms and needs for treatment vary considerably. Moreover, their frequent association with abnormal genetic disorders, such as Trisomy 21 or Heterotaxy, further complicates the task of surgical treatment. Analysing the data is seemingly complex: some associations are exceedingly rare, while in other more common morphologies, the approach is variable and controversial. Although results have greatly improved in the last decades, early and late survival remains suboptimal, sometimes poor. Early mortality greatly varies, along with complexity of pathophysiology and repair, from 5% to over 30%. The dilemma between high operative risk and palliation of the univentricular type is at times daunting. The possibility of surgical cure is discussed according to surgical options but the frequent need for reintervention makes hope elusive. Late survival greatly differs, from 45% to 80% at 5-year follow-up. It is hardly surprising, in the western type of society, that prenatal diagnosis should result in a high rate of termination of pregnancy. This holds particularly true when a chromosomal abnormality is also identified

Considerações acerca do brincar e do estatuto da fantasia a partir de proposições teóricas que baseiam a pesquisa IRDI

This work was designed from the theme of child-play and the statute of fantasy, the theoretical axis of the AP3. It is proposed that the play as a developing route of a particular version concerning the significant related to the construction of the child's own body, to its Otherness and to the world that is presented, as well as the expression of the position of the child as a being in constitution and even a being that (already) is. In its relationship to fantasy - or as a means of phantasmatic expression - the play enables processes of representation and, paradoxically, points to something that resists being represented, although it continues to operate in the psychism.Este trabajo fue diseñado desde el tema del jugar y el estatuto de la fantasía, eje teórico de la AP3. Se propone el jugar como un medio para elaborar una versión particular de los significantes relacionados a la construcción del propio cuerpo delniño, a su Otro y al mundo que se presenta a el, así como expresión de la posición del niño como sujeto en constitución e incluso sujeto que (ya) es. En su relación con la fantasía - o como medio de expresión fantasmática -, el jugar permite procesos de representación y, paradójicamente, apunta a algo que se resiste a ser representado, pero sigue funcionando en la psique.Este trabalho foi concebido a partir da temática sobre o brincar e o estatuto da fantasia, eixo teórico da AP3. Propõe-se o brincar como via de elaboração de uma versão particular acerca dos significantes relacionados à construção do próprio corpo da criança, ao seu Outro e ao mundo que a ela se apresenta, assim como expressão da posição da criança como sujeito em constituição e mesmo sujeito que (já) é. Em sua relação com a fantasia - ou como via de expressão fantasmática -, o brincar viabiliza processos de representação e, paradoxalmente, aponta para algo que resiste a ser representado, mas que continua a atuar no psiquismo

Which BRCA genetic testing programs are ready for implementation in health care? A systematic review of economic evaluations

Purpose: There is considerable evidence regarding the efficacy and effectiveness of BRCA genetic testing programs, but whether they represent good use of financial resources is not clear. Therefore, we aimed to identify the main health-care programs for BRCA testing and to evaluate their cost-effectiveness. Methods: We performed a systematic review of full economic evaluations of health-care programs involving BRCA testing. Results: Nine economic evaluations were included, and four main categories of BRCA testing programs were identified: (i) populationbased genetic screening of individuals without cancer, either comprehensive or targeted based on ancestry; (ii) family history (FH)-based genetic screening, i.e., testing individuals without cancer but with FH suggestive of BRCA mutation; (iii) familial mutation (FM)- based genetic screening, i.e., testing individuals without cancer but with known familial BRCA mutation; and (iv) cancer-based genetic screening, i.e., testing individuals with BRCA-related cancers. Conclusions: Currently BRCA1/2 population-based screening represents good value for the money among Ashkenazi Jews only. FHbased screening is potentially very cost-effective, although further studies that include costs of identifying high-risk women are needed. There is no evidence of cost-effectiveness for BRCA screening of all newly diagnosed cases of breast/ovarian cancers followed by cascade testing of relatives, but programs that include tools for identifying affected women at higher risk for inherited forms are promising. Cost-effectiveness is highly sensitive to the cost of BRCA1/2 testing

Are knowledge and skills acquired during the Master Degree in Nursing actually put into practice? A pilot study in Italy

Background. Literature on the evaluation of the Master’s Degree in Nursing is scarce. The objective of this pilot study was to test a questionnaire aimed at monitoring the activities of nurses after receiving the Master’s degree. Methods. An electronic questionnaire was administered to 36 graduates who obtained the Master’s degree during the academic year 2010/2011. Results. Almost 80% of the participants judged their level of improvement in knowledge and skills during the course to have been satisfactory, but the level of implementation of these competencies at work was quite low. Conclusion. Competencies acquired during the Master’s degree course are not always put into practice

Adherence to the Mediterranean Diet and Circulating Levels of Sirtuin 4 in Obese Patients: A Novel Association

PURPOSE: This study was aimed at evaluating sirtuin 4 (Sirt4) levels in obese individuals, in relation to their adherence to the Mediterranean diet (MD), a healthy dietary pattern characterized by high antioxidant capacity, and markers of visceral fat storage. SUBJECTS/METHODS: Forty-three obese patients (44% males; BMI: 36.7-58.8 kg/m2) were consecutively included. PREvención con DIeta MEDiterránea (PREDIMED) and the 7-day food records were used to assess the adherence to MD and dietary pattern, respectively. Visceral adiposity index (VAI) was calculated. Sirt4 levels were detected by ELISA method. RESULTS: The majority of the obese participants (62.8%) had an average adherence to MD. Compared with average adherers, low adherers had higher BMI, energy intake, and percentage of energy from lipids, mainly saturated fat and polyunsaturated fatty acids (PUFA), and lower Sirt4 levels. After adjusting for BMI, Sirt4 levels remained negatively correlated with VAI. After adjusting for total energy intake, Sirt4 levels remained negatively associated with PREDIMED and consumption of n-3 PUFA, vitamins C and E. The threshold value of PREDIMED predicting the lowest decrease in Sirt4 levels was found at a score of 6. CONCLUSIONS: Less reduced Sirt4 levels in obese patients adhering to MD suggest a further aspect of the antioxidant advantage of MD
