Family health nursing care: weaknesses and strengths in the Unified Health System

OBJECTIVETo analyze the weaknesses and strengths of nursing care in the Family Health Strategy and its interfaces with the Unified Health System network.METHODA qualitative study performed by means of semi-structured interviews and systematic observations, with the participation of a nursing team of 15 people from October of 2012 to January of 2013.RESULTSStrengths that were emphasized: the nurse's versatility in conducting users within the unit and the health system, therefore directly acting upon access to these services. The nurse is the main subject that participates in the care processes for the person, family and social groups. Weaknesses that were highlighted: fragile embracement and low resolution of users' and families' problems.CONCLUSIONThe nursing care process in health units still lacks collective articulation, involvement of the team, and decentralization of the decisions.

The study assesses firstly the evaluation process of the first generation of asylum instruments while underlining the possibilities to improve it. It analyses secondly the asylum "acquis" regarding distribution of refugees between Member States, the eligibility for protection, the status of protected persons regarding detention and vulnerability, asylum procedures and the external dimension by formulating short-term recommendations of each area. Its last part is devoted to the long term evolution of the Common European Asylum System regarding the legal context including the accession of the EU to the Geneva Convention, the institutional perspectives including the new European Support Office, the jurisdictional perspective, the substantive perspective, the distributive perspective and the external perspective.

Workloads and strain process in Community Health Agents

ABSTRACT OBJECTIVE To identify the workloads present in the work activities of community health agents (CHAs) and the resulting strain processes. METHOD A descriptive, exploratory, cross-sectional and quantitative study conducted with 137 CHAs. Data were collected through a questionnaire and interview guided by the health surveillance software called SIMOSTE (Health Monitoring System of Nursing Workers), following the ethical codes of the current law. RESULTS In total, were identified 140 workloads involved in 122 strain processes, represented by the occurrence of health problems of the CHAs. The mechanical (55.00%) and biological (16.43%) loads stood out. The most common strain processes were the external causes of morbidity and mortality (62.31%) and diseases of the musculoskeletal system and connective tissue (10.66%). CONCLUSION From the identified overloads, it became evident that all workloads are present in the work process of CHAs, highlighting the mechanical load, represented mainly by external causes of morbidity and mortality that are related to occupational accidents.

The TetR-type MfsR protein of the integrative and conjugative element (ICE) ICEclc controls both a putative efflux system and initiation of ICE transfer.

Integrative and conjugating elements (ICE) are self-transferable DNAs widely present in bacterial genomes, which often carry a variety of auxiliary genes of potential adaptive benefit. One of the model ICE is ICEclc, an element originally found in Pseudomonas knackmussii B13 and known for its propensity to provide its host with the capacity to metabolize chlorocatechols and 2-aminophenol. In this work, we studied the mechanism and target of regulation of MfsR, a TetR-type repressor previously found to exert global control on ICEclc horizontal transfer. By using a combination of ICEclc mutant and transcriptome analysis, gene reporter fusions, and DNA binding assays, we found that MfsR is a repressor of both its own expression and that of a gene cluster putatively coding for a major facilitator superfamily efflux system on ICEclc (named mfsABC). Phylogenetic analysis suggests that mfsR was originally located immediately adjacent to the efflux pump genes but became displaced from its original cis target DNA by a gene insertion. This resulted in divergence of the original bidirectional promoters into two separated individual regulatory units. Deletion of mfsABC did not result in a strong phenotype, and despite screening a large number of compounds and conditions, we were unable to define the precise current function or target of the putative efflux pump. Our data reconstruct how the separation of an ancestor mfsR-mfsABC system led to global control of ICEclc transfer by MfsR.

Diversity and regional inequalities: Assessing the outcomes of the Spanish 'System of Health Care Services'

The consolidation of a universal health system coupled with a process of regionaldevolution characterise the institutional reforms of the National Health System(NHS) in Spain in the last two decades. However, scarce empirical evidence hasbeen reported on the effects of both changes in health inputs, outputs andoutcomes, both at the country and at the regional level. This paper examinesthe empirical evidence on regional diversity, efficiency and inequality ofthese changes in the Spanish NHS using cross-correlation, panel data andexpenditure decomposition analysis. Results suggest that besides significantheterogeneity, once we take into account region-specific needs there is evidenceof efficiency improvements whilst inequalities in inputs and outcomes, althoughmore visible , do not appear to have increased in the last decade. Therefore,the devolution process in the Spanish Health System offers an interesting casefor the experimentation of health reforms related to regional diversity butcompatible with the nature of a public NHS, with no sizeable regionalinequalitiest.

Social security in theory and practice (II): Efficiency theories, narrative theories and implications for reform

166 countries have some kind of public old age pension. What economic forcescreate and sustain old age Social Security as a public program? Mulligan and Sala-i-Martin (1999b) document several of the internationally and historically common features of social security programs, and explore "political" theories of Social Security. This paper discusses the "efficiency theories", which view creation of the SS program as a full of partial solution to some market failure. Efficiency explanations of social security include the "SS as welfare for the elderly" the "retirement increases productivity to optimally manage human capital externalities", "optimal retirement insurance", the "prodigal father problem", the "misguided Keynesian", the "optimal longevity insurance", the "governmenteconomizing transaction costs", and the "return on human capital investment". We also analyze four "narrative" theories of social security: the "chain letter theory", the "lump of labor theory", the "monopoly capitalism theory", and the "Sub-but-Nearly-Optimal policy response to private pensions theory".The political and efficiency explanations are compared with the international and historical facts and used to derive implications for replacing the typical pay-as-you-go system with a forced savings plan. Most of the explanations suggest that forced savings does not increase welfare, and may decrease it.

Proving the performance of a new revenue management system

Revenue management (RM) is a complicated business process that can best be described ascontrol of sales (using prices, restrictions, or capacity), usually using software as a tool to aiddecisions. RM software can play a mere informative role, supplying analysts with formatted andsummarized data who use it to make control decisions (setting a price or allocating capacity fora price point), or, play a deeper role, automating the decisions process completely, at the otherextreme. The RM models and algorithms in the academic literature by and large concentrateon the latter, completely automated, level of functionality.A firm considering using a new RM model or RM system needs to evaluate its performance.Academic papers justify the performance of their models using simulations, where customerbooking requests are simulated according to some process and model, and the revenue perfor-mance of the algorithm compared to an alternate set of algorithms. Such simulations, whilean accepted part of the academic literature, and indeed providing research insight, often lackcredibility with management. Even methodologically, they are usually awed, as the simula-tions only test \within-model" performance, and say nothing as to the appropriateness of themodel in the first place. Even simulations that test against alternate models or competition arelimited by their inherent necessity on fixing some model as the universe for their testing. Theseproblems are exacerbated with RM models that attempt to model customer purchase behav-ior or competition, as the right models for competitive actions or customer purchases remainsomewhat of a mystery, or at least with no consensus on their validity.How then to validate a model? Putting it another way, we want to show that a particularmodel or algorithm is the cause of a certain improvement to the RM process compared to theexisting process. We take care to emphasize that we want to prove the said model as the causeof performance, and to compare against a (incumbent) process rather than against an alternatemodel.In this paper we describe a \live" testing experiment that we conducted at Iberia Airlineson a set of flights. A set of competing algorithms control a set of flights during adjacentweeks, and their behavior and results are observed over a relatively long period of time (9months). In parallel, a group of control flights were managed using the traditional mix of manualand algorithmic control (incumbent system). Such \sandbox" testing, while common at manylarge internet search and e-commerce companies is relatively rare in the revenue managementarea. Sandbox testing has an undisputable model of customer behavior but the experimentaldesign and analysis of results is less clear. In this paper we describe the philosophy behind theexperiment, the organizational challenges, the design and setup of the experiment, and outlinethe analysis of the results. This paper is a complement to a (more technical) related paper thatdescribes the econometrics and statistical analysis of the results.

Monitoring the university admissions process in Spain

The examinations taken by high-school graduates in Spain and the role ofthe examination in the university admissions process are described. Thefollowing issues arising in the assessment of the process are discussed:reliability of grading, comparability of the grades and scores(equating),maintenance of standards, and compilation and use of the grading process,and their integration in the operational grading are proposed. Variousschemes for score adjustment are reviewed and feasibility of theirimplementation discussed. The advantages of pretesting of items and ofempirical checks of experts' judgements are pointed out. The paperconcludes with an outline of a planned reorganisation of the highereducation in Spain, and with a call for a comprehensive programme ofempirical research concurrent with the operation of the examination andscoring system.

Exploring the implementation of a medication adherence programme by community pharmacists : a qualitative study

Background Medication adherence has been identified as an important factor for clinical success. Twenty-four Swiss community pharmacists participated in the implementation of an adherence support programme for patients with hypertension, diabetes mellitus and/or dyslipidemia. The programme combined tailored consultations with patients about medication taking (expected at an average of one intervention per month) and the delivery of each drug in an electronic monitoring system (MEMS6?). Objective To explore pharmacists' perceptions and experiences with implementation of the medication adherence programme and to clarify why only seven patients were enrolled in total. Setting Community pharmacies in French-speaking Switzerland. Method Individual in-depth interviews were audio-recorded, with 20 of the pharmacists who participated in the adherence programme. These were transcribed verbatim, coded and thematically analysed. Process quality was ensured by using an audit trail detailing the development of codes and themes; furthermore, each step in the coding and analysis was verified by a second, experienced qualitative researcher. Main outcome measure Community pharmacists' experiences and perceptions of the determining factors influencing the implementation of the adherence programme. Results Four major barriers were identified: (1) poor communication with patients resulting in insufficient promotion of the programme; (2) insufficient collaboration with physicians; (3) difficulty in integrating the programme into pharmacy organisation; and (4) insufficient pharmacist motivation. This was related to the remuneration perceived as insufficient and to the absence of clear strategic thinking about the pharmacist position in the health care system. One major facilitator of the programme's implementation was pre-existing collaboration with physicians. Conclusion A wide range of barriers was identified. The implementation of medication adherence programmes in Swiss community pharmacies would benefit from an extended training aimed at developing communication and change management skills. Individualised onsite support addressing relevant barriers would also be necessary throughout the implementation process.

Canine distemper virus : persistence and pathology in the central nervous system

Résumé : Le virus de la maladie de Carré (en anglais: canine distemper virus, CDV) qui est pathogène pour les chiens et autres carnivores, est très semblable au virus de la rougeole humaine (en anglais MV). Ces deux virus font partie du genre des Morbillivirus qui appartient à la famille des Paramyxoviridae. Ils induisent des complications dans le système nerveux central (SNC). Au stade précoce et aigu de l'infection du SNC, le CDV induit une démyélinisation (1). Ce stade évolue dans certains cas vers une infection chronique avec progression de la démyélinisation. Pendant le stade précoce, qui suit en général de trois semaines les premiers symptômes, le processus de démyélinisation est associé à la réplication du virus et n'est pas considéré comme inflammatoire (1). Par contre, au stade chronique, la progression des plaques de démyélinisation semble être plutôt liée à des processus immunogènes caractéristiques (2), retrouvés également dans la sclérose en plaques (SEP) chez les humains. Pour cette raison, le CDV est considéré comme un modèle pour la SEP humaine et aussi pour l'étude des maladies et complications induites par les Morbillivirus en général (3). Dans notre laboratoire, nous avons utilisé la souche A75/17-CDV, qui est considérée comme le modèle des souches neurovirulentes de CDV. Nous avons cherché en premier lieu à établir un système robuste pour infecter des cultures neuronales avec le CDV. Nous avons choisi les cultures primaires de l'hippocampe du nouveau-né de rat (4), que nous avons ensuite infecté avec une version modifiée du A75/17, appelée rgA75/17-V (5). Dans ces cultures, nous avons prouvé que le CDV infecte des neurones et des astrocytes. Malgré une infection qui se diffuse lentement entre les cellules, cette infection cause une mort massive aussi bien des neurones infectés que non infectés. En parallèle, les astrocytes perdent leur morphologie de type étoilé pour un type polygonal. Finalment, nous avons trouvé une augmentation importante de la concentration en glutamate dans le milieu de culture, qui laisse présumer une sécrétion de glutamate par les cultures infectées (6). Nous avons ensuite étudié le mécanisme des effets cytopathiques induits par le CDV. Nous avons d'abord démontré que les glycoprotéines de surface F et H du CDV s'accumulent massivement dans le réticulum endoplasmique (RE). Cette accumulation déclenche un stress du RE, qui est caractérisé par une forte expression du facteur de transcription proapoptotique CHOP/GADD 153 et de le la calreticuline (CRT). La CRT est une protéine chaperonne localisée dans le RE et impliquée dans l'homéostasie du calcium (Ca2+) et dans le repliement des protéines. En transfectant des cellules de Vero avec des plasmides codant pour plusieurs mutants de la glycoprotéine F de CDV, nous avons démontré une corrélation entre l'accumulation des protéines virales dans le RE et l'augmentation de l'expression de CRT, le stress du RE et la perte de l'homéostasie du Ca2+. Nous avons obtenu des résultats semblables avec des cultures de cellules primaires de cerveau de rat. Ces résultats suggèrent que la CRT joue un rôle crucial dans les phénomènes neurodégénératifs pendant l'infection du SNC, notamment par le relazgage du glutamate via le Ca2+. De manière intéressante, nous démontrons également que l'infection de CDV induit une fragmentation atypique de la CRT. Cette fragmentation induit une re-localisation et une exposition sélective de fragments amino-terminaux de la CRT, connus pour êtres fortement immunogènes à la surface des cellules infectées et non infectées. A partir de ce résultat et des résultats précédents, nous proposons le mécanisme suivant: après l'infection par le CDV, la rétention dans le RE des protéines F et H provoque un stress du RE et une perte de l'homéostasie du Ca2+. Ceci induit la libération du glutamate, qui cause une dégénération rapide du SNC (sur plusieurs jours ou semaines) correspondant à la phase aiguë de la maladie chez le chien. En revanche, les fragments amino-terminaux de la CRT libérés à la surface des cellules infectées peuvent avoir un rôle important dans l'établissement d'une démyélinisation d'origine immunogène, typique de la phase chronique de l'infection de CDV. Summary : The dog pathogen canine distemper virus (CDV), closely related to the human pathogen measles virus (MV), belongs to the Morbillivirus genus of the Paramyxoviridae family. Both CDV and NIV induce complications in the central nervous system (CNS). In the acute early stage of the infection in CNS, the CDV infection induces demyelination. This stage is sometimes followed by a late persistent stage of infection with a progression of the demyelinating lesions (1). The acute early stage occurs around three weeks after the infection and demyelinating processes are associated with active virus replication and are not associated to inflammation (1). In contrast during late persistent stage, the demyelination plaque progression seems to be mainly due to an immunopathological process (2), which characteristics are shared in many aspects with the human disease multiple sclerosis (MS). For these reasons, CDV is considered as a model for human multiple sclerosis, as well as for the study of Morbillivirus-mediated pathogenesis (3). In our laboratory, we used the A75/17-CDV strain that is considered to be the prototype of neurovirulent CDV strain. We first sought to establish a well characterized and robust model for CDV infection of a neuronal culture. We chose primary cultures from newborn rat hippocampes (4) that we infected with a modified version of A75/17, called rgA75/17-V (5). In these cultures, we showed that CDV infects both neurons and astrocytes. While the infection spreads only slowly to neighbouring cells, it causes a massive death of neurons, which includes also non-infected neurons. In parallel, astrocytes undergo morphological changes from the stellate type to the polygonal type. The pharmacological blocking of the glutamate receptors revealed an implication of glutamatergic signalling in the virus-mediated cytopathic effect. Finally, we found a drastic increase concentration of glutamate in the culture medium, suggesting that glutamate was released from the cultured cells (6). We further studied the mechanism of the CDV-induced cytopathic effects. We first demonstrated that the CDV surface glycoprotein F and H markedly accumulate in the endoplasmic reticulum (ER). This accumulation triggers an ER stress, which is characterized by increased expression of the proapoptotic transcription factor CHOP/GADD 153 and calreticulin (CRT). CRT is an ER resident chaperon involved in the Ca2+ homeostasis and in the response to misfolded proteins. Transfections of Vero cells with plasmids encoding various CDV glycoprotein mutants reveal a correlation between accumulation of viral proteins in the ER, CRT overexpression, ER stress and alteration of ER Ca2+ homeostasis. Importantly, similar results are also obtained in primary cell cultures from rat brain. These results suggest that CRT plays a crucial role in CNS infection, particularly due to CRT involvement in Ca2+ mediated glutamate releases, and subsequent neurodegenerative disorders. Very intriguingly, we also demonstrated that CDV infection induces an atypical CRT fragmentation, with relocalisation and selective exposure of the highly immunogenic CRT N-terminal fragments at the surface of infected and neighbouring non-infected cells. Altogether our results combined with previous findings suggest the following scenario. After CDV infection, F and H retention alter Ca2+ homeostasis, and induce glutamate release, which in turn causes rapid CNS degeneration (within days or a week) corresponding to the acute phase of the disease in dogs. In contrast, the CRT N-terminal fragments released at the surface of infected cells may rather have an important role in the establishment of the autoimmune demyelination in the late stage of CDV infection.

Epithelial to mesenchymal transition in the pathogenesis of uterine malignant mixed Müllerian tumours: the role of ubiquitin proteasome system and therapeutic opportunities.

Malignant mixed Müllerian tumours (malignant mixed mesodermal tumours, MMMT) of the uterus are metaplastic carcinomas with a sarcomatous component and thus they are also called carcinosarcomas. It has now been accepted that the sarcomatous component is derived from epithelial elements that have undergone metaplasia. The process that produces this metaplasia is epithelial to mesenchymal transition (EMT), which has recently been described as a neoplasia-associated programme shared with embryonic development and enabling neoplastic cells to move and metastasise. The ubiquitin proteasome system (UPS) regulates the turnover and functions of hundreds of cellular proteins. It plays important roles in EMT by being involved in the regulation of several pathways participating in the execution of this metastasis-associated programme. In this review the specifi c role of UPS in EMT of MMMT is discussed and therapeutic opportunities from UPS manipulations are proposed.

Ubiquitination and the Ubiquitin-Proteasome System as regulators of transcription and transcription factorsin epithelial mesenchymal transition of cancer.

Epithelial to Mesenchymal Transition (EMT) in cancer is a process that allows cancer cells to detach from neighboring cells, become mobile and metastasize and shares many signaling pathways with development. Several molecular mechanisms which regulate oncogenic properties in neoplastic cells such as proliferation, resistance to apoptosis and angiogenesis through transcription factors or other mediators are also regulators of EMT. These pathways and downstream transcription factors are, in their turn, regulated by ubiquitination and the Ubiquitin-Proteasome System (UPS). Ubiquitination, the covalent link of the small 76-amino acid protein ubiquitin to target proteins, serves as a signal for protein degradation by the proteasome or for other outcomes such as endocytosis, degradation by the lysosome or directing these proteins to specific cellular compartments. This review discusses aspects of the regulation of EMT by ubiquitination and the UPS and underlines its complexity focusing on transcription and transcription factors regulating EMT and are being regulated by ubiquitination.

How useful is satellite positioning system (GPS) to track gait parameters? A review.

Over the last century, numerous techniques have been developed to analyze the movement of humans while walking and running. The combined use of kinematics and kinetics methods, mainly based on high speed video analysis and forceplate, have permitted a comprehensive description of locomotion process in terms of energetics and biomechanics. While the different phases of a single gait cycle are well understood, there is an increasing interest to know how the neuro-motor system controls gait form stride to stride. Indeed, it was observed that neurodegenerative diseases and aging could impact gait stability and gait parameters steadiness. From both clinical and fundamental research perspectives, there is therefore a need to develop techniques to accurately track gait parameters stride-by-stride over a long period with minimal constraints to patients. In this context, high accuracy satellite positioning can provide an alternative tool to monitor outdoor walking. Indeed, the high-end GPS receivers provide centimeter accuracy positioning with 5-20 Hz sampling rate: this allows the stride-by-stride assessment of a number of basic gait parameters--such as walking speed, step length and step frequency--that can be tracked over several thousand consecutive strides in free-living conditions. Furthermore, long-range correlations and fractal-like pattern was observed in those time series. As compared to other classical methods, GPS seems a promising technology in the field of gait variability analysis. However, relative high complexity and expensiveness--combined with a usability which requires further improvement--remain obstacles to the full development of the GPS technology in human applications.

Application of a support system to the design of wastewater treatment plants

This paper presents a case study that explores the advantages that can be derived from the use of a design support system during the design of wastewater treatment plants (WWTP). With this objective in mind a simplified but plausible WWTP design case study has been generated with KBDS, a computer-based support system that maintains a historical record of the design process. The study shows how, by employing such a historical record, it is possible to: (1) rank different design proposals responding to a design problem; (2) study the influence of changing the weight of the arguments used in the selection of the most adequate proposal; (3) take advantage of keywords to assist the designer in the search of specific items within the historical records; (4) evaluate automatically thecompliance of alternative design proposals with respect to the design objectives; (5) verify the validity of previous decisions after the modification of the current constraints or specifications; (6) re-use the design records when upgrading an existing WWTP or when designing similar facilities; (7) generate documentation of the decision making process; and (8) associate a variety of documents as annotations to any component in the design history. The paper also shows one possible future role of design support systems as they outgrow their current reactive role as repositories of historical information and start to proactively support the generation of new knowledge during the design process

Gaussian process framework for pervasive estimation of swimming velocity with body-worn IMU

Presented is an accurate swimming velocity estimation method using an inertial measurement unit (IMU) by employing a simple biomechanical constraint of motion along with Gaussian process regression to deal with sensor inherent errors. Experimental validation shows a velocity RMS error of 9.0 cm/s and high linear correlation when compared with a commercial tethered reference system. The results confirm the practicality of the presented method to estimate swimming velocity using a single low-cost, body-worn IMU.
