Revisión sistemática de la literatura de las intervenciones diseñadas para el comportamiento de automedicación no responsable

La automedicación no responsable se ha convertido en un problema de salud pública global en las últimas décadas, por sus consecuencias individuales (por ejemplo, la intoxicación) y colectivas (por ejemplo, la resistencia microbiana a los antibióticos). Las intervenciones orientadas a este comportamiento han sido aisladas y muy diferentes. Aunque se tiene evidencia de que su aplicación puede traer beneficios en diferentes poblaciones, no se halló en la literatura una compilación sistemática de dichas intervenciones. El objetivo de la presente revisión es sistematizar la literatura científica sobre las diferentes alternativas de intervención del comportamiento individual de automedicación no responsable. En cuanto al método, la revisión de literatura involucró la búsqueda sistemática de “automedicación” e “intervención” en las bases de datos académicas internacionales con contenidos de psicología, suscritas por la Biblioteca de la Universidad del Rosario. Como resultado se encontró que las intervenciones orientadas al comportamiento de automedicación no responsable se pueden clasificar en dos grandes grupos: (a) intervenciones regulatorias, con dirección “arriba hacia abajo”, que suponen una acción de los Estados nacionales por medio de sus legislaciones o de entidades internacionales (por ejemplo, Organización Mundial de la Salud); y (b) intervenciones educativas, con dirección “abajo hacia arriba”, que suponen acciones con individuos y comunidades con el fin de enseñar acerca del uso adecuado de los medicamentos. Se concluye acerca de la necesidad de complementar ambos tipos de intervención, los cuales, si bien demuestran resultados positivos, aisladamente son insuficientes para contrarrestar integralmente este fenómeno creciente y complejo.

Disturbi dell'informazione, nuovi media e libertà di manifestazione del pensiero

L’elaborato affronta il tema della massiccia diffusione di disinformazione tramite internet sotto il profilo del diritto costituzionale, nell’ottica di indagare se le dimensioni del fenomeno richiedano l’elaborazione di principi e soluzioni nuove ovvero se i paradigmi costituzionali enucleati dalla tradizione costituzionalistica con riferimento alla libertà d’espressione forniscano gli strumenti sufficienti per un intervento efficace. In tale ottica, il lavoro premette una ricostruzione del fenomeno della disinformazione nel tentativo di individuare il perimetro socio-cognitivo e tecnologico entro cui la medesima prolifera, descrivendo gli elementi che distinguono l’informazione diffusa dai nuovi media rispetto a quella veicolata dai media mainstream. Ciò premesso, lo studio passa a delineare lo “statuto costituzionale” del falso, indagando la rilevanza che la menzogna assume sotto il profilo costituzionale nel suo rapporto con la libertà di manifestazione del pensiero negli ordinamenti interno, europeo e statunitense. L’analisi prosegue poi con l’esame delle politiche di contrasto alla disinformazione introdotte da singoli Stati (prevalentemente Germania, Francia e Italia), Unione europea, e piattaforme, con l’obiettivo di mettere in luce vantaggi e limiti dei modelli di eteroregolamentazione, coregolamentazione e autoregolamentazione. Da ultimo, l’elaborato scompone alcune delle azioni e misure passate in rassegna e le analizza con la lente d’ingrandimento della libertà di manifestazione del pensiero, ordinandone i contenuti secondo la specifica propensione a comprimere la libertà d’espressione. L’indagine si conclude con alcuni brevi spunti conclusivi che evidenziano l’esigenza, in base ai principi costituzionali analizzati, che eventuali interventi normativi siano se del caso volti alla regolazione delle piattaforme, ovvero dei “contenitori”, lasciano i contenuti al libero scambio delle idee.

La nuova eGovernance sanitaria europea: verso una piena integrazione della digitalizzazione nei sistemi sanitari degli Stati membri

L’elaborato approfondisce il diritto alla salute nell’ordinamento dell’Unione europea, con la consapevolezza che il settore della sanità, nella complessità di una tensione perdurante tra la sua matrice sociale e l’applicazione di logiche europee di mercato, rappresenta un ambito da sempre sottratto all’intervento diretto e vincolante delle istituzioni. Contemporaneamente, prende spunto dall’osservazione della transizione digitale dei sistemi sanitari nazionali per proporre una rilettura dei tradizionali equilibri istituzionali tra ordinamenti e constatare il grado di influenza dell’Unione oltre la dimensione transfrontaliera. Infatti, per le attuali esigenze di sostenibilità dei sistemi di tutela della salute e per il valore aggiunto riconosciuto alle azioni europee nel corso della gestione della pandemia da Covid-19, l’eHealth ha rappresentato l’occasione per una vigorosa intrusione delle istituzioni europee entro prerogative tipicamente statuali, fino all’emersione di una eGovernance sanitaria europea. Pertanto, la trattazione compie un percorso evolutivo che muove dalla Direttiva 2011/24 sull’assistenza transfrontaliera e l’assistenza sanitaria online, in combinato disposto con il complesso degli atti di soft law connessi, per verificarne l’esiguo impatto sui sistemi sanitari degli Stati membri e, alla luce dei recenti investimenti strategici ed interventi normativi rilevanti in tema di tecnologie applicate alla sanità, riconoscerne il sostanziale superamento. In particolare, il confronto tra l’insufficiente livello di digitalizzazione raggiunto finora nei sistemi sanitari degli Stati membri ed il tenore della Proposta di regolamento sullo European Health Data Space suggerisce l’evoluzione dell’impianto di governo dei dati sanitari stabilito nella Direttiva, a partire dalla previsione di una disciplina comune sulla cartella sanitaria. A questo proposito, l’interoperabilità tra tecnologie diviene un presupposto operativo indefettibile, che corrobora la natura ‘tecnologicamente condizionata’ del diritto alla salute e propone l’idea che la sanità digitale rappresenti un passo in avanti verso un’assistenza europea uniforme.

Evaluating non-price effects of regulatory and competition enforcement interventions

This thesis provides an ex-post evaluation of the effects of regulatory and competition policy enforcement interventions on non-price dimensions of competition. Chapter 1 examines the effects of a merger between two large Dutch supermarket chains on the variety and composition of product assortment. Chapter 2 and Chapter 3 investigate, both theoretically and empirically, the effects of access regulation in fixed telecoms markets on incentives to invest in superior infrastructure technologies. Non-price effects, together with price effects, are crucial to shed light on the extent of competition in a market and assess the effectiveness of regulatory and competition authorities' interventions. When evaluating non-price effects, however, it is harder to draw conclusions on the overall impact on consumers' welfare.

Role of regulatory T cells in long-term immune dysfunction associated with severe sepsis

Objective: To investigate the role of regulatory T cells in the modulation of long-term immune dysfunction during experimental sepsis. It is well established that sepsis predisposes to development of a pronounced immunosuppression. Nevertheless, the mechanisms underlying the immune dysfunction after sepsis are still not well understood. Design: Prospective experimental study. Setting: University research laboratory. Interventions: Wild-type mice underwent cecal ligation and puncture and were treated with antibiotic during 3 days after surgery. On days 1, 7, or 15 after cecal ligation and puncture, the frequency of regulatory T cells, proliferation of CD4(+) T cells and bacterial counts were evaluated. Fifteen days after cecal ligation and puncture, surviving mice underwent secondary pulmonary infection by intranasal inoculation of nonlethal dose of Legionella pneumophila. Some mice received agonistic glucocorticoid-induced tumor necrosis factor receptor antibody (DTA-1) before induction of secondary infection. Measurements and Main Results: Mice surviving cecal ligation and puncture showed a markedly increased frequency of regulatory T cells in thymus and spleen, which was associated with reduced proliferation of CD4(+) T cells. Fifteen days after cecal ligation and puncture, all sepsis-surviving mice succumbed to nonlethal injection of L. pneumophila. Treatment of mice with DTA-1 antibody reduced frequency of regulatory T cells, restored CD4(+) T cell proliferation, reduced the levels of bacteria in spleen, and markedly improved survival of L. pneumophila infection. Conclusion: These findings suggest that regulatory T cells play an important role in the progression and establishment of immune dysfunction observed in experimental sepsis.

The impact of generic reference pricing interventions in the statin market

The objective of this study was to evaluate the intended and unintended impact on pharmaceutical use and sales of three public financing reforms applied to the prescription of statins: a Spanish generic reference pricing (RP) system for lovastatin and simvastatin, and two competing policies introduced by the Andalusian Public Health Service (APHS) for all statins, first a maximum consumer price (MCP) and then a so called quality prescribing incentive for general practitioners (MCP plus PI).This study is designed as an observational, retrospective, interrupted time series analysis with comparison series (APHS and the rest of Spain) of 46 monthly drug use and sales ratios from January 2001 to October 2004 for each active ingredient in the group of statins.RP has been effective at reducing the volume of sales growth of the off-patent statins, yet its overall impact on sales of all statins has been relatively modest. The quantity and volume of sales impact heavily depends on regulatory RP details such as when the system is introduced, how often it is updated, and how the reference price is calculated.

Cognate microRNA-Gene Regulatory Networks Mediating Glioblastoma Oncogenic Properties

Malignant gliomas, including the most common and fatal form glioblastoma (GBM, WHO grade IV astrocytoma), remain a challenge to treat. In the United States and Europe, more than 30,000 patients per year are newly diagnosed with GBM. Despite ongoing trials, the best currently available multimodal treatment approaches include surgical resection followed by concomitant and adjuvant radiation (RT) and temozolomide (TMZ) therapy, resulting in a low median overall survival (OS) rate ranging from 12.2 - 15.9 months. The important role of genetic and epigenetic changes in DNA, RNA, and protein alteration as well as epigenetic changes secondary to the tumor microenvironment and outside selection pressure (therapeutic interventions), are increasingly being recognized. In GBM treatment, the focus is shifting toward a more patient-centered (personalized) therapy. In this regard, in particular, microRNAs are being increasingly studied. MicroRNAs are non¬protein coding small RNAs that serve as negative gene regulators by binding to a specific sequence in the promoter region of a target gene, thus regulating gene expression. A single microRNA potentially targets hundreds of genes; thus, microRNAs and their cognate target genes have important roles as tumor suppressors and oncogenes as well as regulators of various cancer- specific cellular features, such as proliferation, apoptosis, invasion, and metastasis. The identification of distinct microRNA-gene regulatory networks in GBM patients can be expected to provide novel therapeutic insights by identifying candidate patients for targeted therapies. To this end, in this work we identified and validated clinically relevant and meaningful novel gene- microRNA regulatory networks that correlated with MR tumor phenotypes, histopathology, and patient survival and response rates to therapy. - Le traitement des gliomes malins, y compris sous leur forme la plus commune et meurtrière, le glioblastome (GBM, ou astrocytome de grade IV selon l'OMS), demeure à ce jour un défi. Aux États-Unis et en Europe, un nouveau diagnostic de GBM est prononcé dans plus de 30Ό00 cas par an. En dépit de tests en cours, les meilleures approches thérapeutiques combinées actuellement disponibles comprennent la résection chirurgicale de la tumeur, suivie d'une radiothérapie adjuvante ainsi que d'un traitement au temozolomide (RT/TMZ), thérapies dont résulte une médiane de survie globale basse (overall survival, OS), comprise entre 12.2 et 15.9 mois. On reconnaît de plus en plus le rôle majeur de l'ADN, de l'ARN et de l'altération des protéines ainsi que des modifications épigénétiques, secondaires par rapport au microenvironnement de la tumeur et à la pression de sélection extérieure (les interventions thérapeutiques). Dans le traitement du GBM, le centre d'intérêt se déplace vers une thérapie centrée sur le cas individuel du patient. Dans ce but, en particulier les microARN sont de plus en plus analysés. Les microARN sont de petits ARN non-codants (les protéines) qui servent de régulateurs négatifs de gènes en s'attachant à une séquence spécifique dans la région promotrice d'un gène-cible, régulant ainsi l'expression du gène. Un seul microARN cible potentiellement des centaines de gènes; on a ainsi découvert que les microARN et leurs gènes-cibles apparentés ont une fonction importante en tant que suppresseurs de tumeurs et d'oncogènes, ainsi que comme régulateurs de diverses caractéristiques cellulaires spécifiques du cancer, comme la prolifération, l'apoptose, l'invasion et la métastase. On peut s'attendre à ce que l'identification de réseaux microARN régulateurs de gènes, distincts selon les patients de GBM, fournisse une approche thérapeutique inédite par la détermination des patients susceptibles de réagir favorablement à des thérapies ciblées.

Les interventions communautaires d’activation au Québec et leurs déterminants : orientations institutionnelles, appropriation et gouvernance.

Cette recherche exploratoire a pour objet d’étude la mise en œuvre des interventions d’activation pour l’emploi auprès des prestataires de l’assistance sociale en situation de grande vulnérabilité au Québec. Elle cherche à décrire les pratiques mises en œuvre par des intervenants de la première ligne (« street-level ») au sein des organismes communautaires œuvrant en employabilité, dans le cadre des mesures et programmes de l’agence Emploi- Québec, dans un contexte de contractualisation et partenariat entre le gouvernement et le secteur à but non lucratif. Le mémoire cherche à identifier les processus qui peuvent influencer les pratiques de la première ligne de services lors de l’interaction avec les destinataires du système intégré d’aide financière de dernier recours et d’aide à l’emploi, de même qu’à comprendre les rapports de force en présence lors de la mise en œuvre des interventions. L’on veut répondre aux deux questions suivantes : Quel est le poids relatif du cadre institutionnel du système d’activation et du pouvoir discrétionnaire des intervenants de la première ligne travaillant directement avec les prestataires les plus vulnérables, au sein des organismes communautaires en employabilité? Plus précisément, comment ces deux types de processus interagissent-ils entre eux, pour produire la politique telle que mise en œuvre? On se base sur des approches théoriques sur la mise en œuvre des politiques inspirées des perspectives de « street level bureaucracy » (Lipsky, 1971, 1980; Smith et Lipsky, 1993 ; Hupe & Hill, 2007 ; Brodkin, 2007, 2011, 2012, 2015; Rice, 2012), du néo-institutionnalisme discursif (Schmidt, 2008, 2010) et de l’Ethnographie institutionnelle (Smith, 1999, 2006; Campbell & Gregor, 2008). On considère que la mise en œuvre de la politique d’activation entraîne non seulement une « appropriation » du cadre institutionnel et systémique par les intervenants de première ligne, mais aussi une co-construction de la politique dans un contexte de gouvernance spécifique. La stratégie de recherche est qualitative et s’inspire de l’approche de l’ethnographie institutionnelle en sociologie, qui propose une méthodologie pour retracer les effets des institutions sur les travailleurs dans leur vie quotidienne (Smith, 2005, 1999, 1987; Campbell and Gregor, 2008). Elle comprend : i) des entretiens avec des intervenants communautaires qui fournissent des services d’aide et d’accompagnement pour l’intégration en emploi portant sur certains dossiers de prestataires du système; ii) des entretiens avec des coordinatrices d’organismes communautaires œuvrant en employabilité, et iii) une collecte et une analyse de la documentation institutionnelle et du cadre de réglementation pour la mise en œuvre du système d’activation. L'analyse aborde le discours institutionnel d'une part et, d'autre part, le discours des répondants du secteur communautaire en employabilité concernant leurs interventions auprès des prestataires dans le cadre des programmes et mesures d’E-Q, et leurs « explications » des pratiques quotidiennes.

Institutional pressures on financial services firms: the role of information systems in regulatory compliance

The financial crisis of 2008 led to new international regulatory controls for the governance, risk and compliance of financial services firms. Information systems play a critical role here as political, functional and social pressures may lead to the deinstitutionalization of existing structures, processes and practices. This research examines how an investment management system is introduced by a leading IT vendor across eight client sites in the post-crisis era. Using institutional theory, it examines changes in working practices occurring at the environmental and organizational levels and the ways in which technological interventions are used to apply disciplinary effects in order to prevent inappropriate behaviors. The results extend the constructs of deinstitutionalization and identify empirical predictors for the deinstitutionalization of compliance and trading practices within financial organizations.

Air accident investigation among regulatory agencies

The aim of this manuscript is to describe and compare regulatory aviation agencies according to their subordination and attributions to investigate air accidents. Possible consequences in identifying the contributory factors are also presented. Distinct procedures investigating air accidents among agencies lead to a lack of standardization of the statistics, making it difficult to analyze the data globally. Separately the information does not configure the entire scenario of what occurred, affecting the analysis and subsequent interventions. We recommend a joint and collaborative work between the different committees that operate in the investigation of air accidents.

Report of a European Society of Cardiology-European Association of Percutaneous Cardiovascular Interventions task force on the evaluation of coronary stents in Europe: executive summary.

The evaluation for European Union market approval of coronary stents falls under the Medical Device Directive that was adopted in 1993. Specific requirements for the assessment of coronary stents are laid out in supplementary advisory documents. In response to a call by the European Commission to make recommendations for a revision of the advisory document on the evaluation of coronary stents (Appendix 1 of MEDDEV 2.7.1), the European Society of Cardiology (ESC) and the European Association of Percutaneous Cardiovascular Interventions (EAPCI) established a Task Force to develop an expert advisory report. As basis for its report, the ESC-EAPCI Task Force reviewed existing processes, established a comprehensive list of all coronary drug-eluting stents that have received a CE mark to date, and undertook a systematic review of the literature of all published randomized clinical trials evaluating clinical and angiographic outcomes of coronary artery stents between 2002 and 2013. Based on these data, the TF provided recommendations to inform a new regulatory process for coronary stents. The main recommendations of the task force include implementation of a standardized non-clinical assessment of stents and a novel clinical evaluation pathway for market approval. The two-stage clinical evaluation plan includes recommendation for an initial pre-market trial with objective performance criteria (OPC) benchmarking using invasive imaging follow-up leading to conditional CE-mark approval and a subsequent mandatory, large-scale randomized trial with clinical endpoint evaluation leading to unconditional CE-mark. The data analysis from the systematic review of the Task Force may provide a basis for determination of OPC for use in future studies. This paper represents an executive summary of the Task Force's report.

For-profit business safety interventions: A systematic, descriptive review of the literature

The purpose of this research was to determine if principles from organizational theory could be used as a framework to compare and contrast safety interventions developed by for-profit industry for the time period 1986–1996. A literature search of electronic databases and manual search of journals and local university libraries' book stacks was conducted for safety interventions developed by for-profit businesses. To maintain a constant regulatory environment, the business sectors of nuclear power, aviation and non-profits were excluded. Safety intervention evaluations were screened for scientific merit. Leavitt's model from organization theory was updated to include safety climate and renamed the Updated Leavitt's Model. In all, 8000 safety citations were retrieved, 525 met the inclusion criteria, 255 met the organizational safety intervention criteria, and 50 met the scientific merit criteria. Most came from non-public health journals. These 50 were categorized by the Updated Leavitt's Model according to where within the organizational structure the intervention took place. Evidence tables were constructed for descriptive comparison. The interventions clustered in the areas of social structure, safety climate, the interaction between social structure and participants, and the interaction between technology and participants. No interventions were found in the interactions between social structure and technology, goals and technology, or participants and goals. Despite the scientific merit criteria, many still had significant study design weaknesses. Five interventions tested for statistical significance but none of the interventions commented on the power of their study. Empiric studies based on safety climate theorems had the most rigorous designs. There was an attempt in these studies to address randomization amongst subjects to avoid bias. This work highlights the utility of using the Updated Leavitt's Model, a model from organizational theory, as a framework when comparing safety interventions. This work also highlights the need for better study design of future trials of safety interventions. ^

Regulatory governance of ‘training markets’, ‘market failure’, and ‘quasi’ markets: historical dimensions of the post-initial training market in the Netherlands

This article examines regulatory governance of the post-initial training market in The Netherlands. From an historical perspective on policy formation processes, it examines market formation in terms of social, economic, and cultural factors in the development of provision and demand for post-initial training; the roles of stakeholders in the longterm construction of regulatory governance of the market; regulation of and public providers; policy responses to market failure; and tripartite division of responsibilities between the state, social partners, commercial and publicly-funded providers. Historical description and analysis examine policy narratives of key stakeholders with reference to: a) influence of societal stakeholders on regulatory decision-making; b) state regulation of the post-initial training market; c) public intervention regulating the market to prevent market failure; d) market deregulation, competition, employability and individual responsibility; and, e) regulatory governance to prevent ‘allocative failure’ by the market in non-delivery of post-initial training to specific target groups, particularly the low-qualified. Dominant policy narratives have resulted in limited state regulation of the supply-side, a tripartite system of regulatory governance by the state, social partners and commercial providers as regulatory actors. Current policy discourses address interventions on the demand-side to redistribute structures of opportunity throughout the life courses of individuals. Further empirical research from a comparative historical perspective is required to deepen contemporary understandings of regulatory governance of markets and the commodification of adult learning in knowledge societies and information economies.

Impact Of Pharmacist Interventions On Drug-related Problems And Laboratory Markers In Outpatients With Human Immunodeficiency Virus Infection.

Substantial complexity has been introduced into treatment regimens for patients with human immunodeficiency virus (HIV) infection. Many drug-related problems (DRPs) are detected in these patients, such as low adherence, therapeutic inefficacy, and safety issues. We evaluated the impact of pharmacist interventions on CD4+ T-lymphocyte count, HIV viral load, and DRPs in patients with HIV infection. In this 18-month prospective controlled study, 90 outpatients were selected by convenience sampling from the Hospital Dia-University of Campinas Teaching Hospital (Brazil). Forty-five patients comprised the pharmacist intervention group and 45 the control group; all patients had HIV infection with or without acquired immunodeficiency syndrome. Pharmaceutical appointments were conducted based on the Pharmacotherapy Workup method, although DRPs and pharmacist intervention classifications were modified for applicability to institutional service limitations and research requirements. Pharmacist interventions were performed immediately after detection of DRPs. The main outcome measures were DRPs, CD4+ T-lymphocyte count, and HIV viral load. After pharmacist intervention, DRPs decreased from 5.2 (95% confidence interval [CI] =4.1-6.2) to 4.2 (95% CI =3.3-5.1) per patient (P=0.043). A total of 122 pharmacist interventions were proposed, with an average of 2.7 interventions per patient. All the pharmacist interventions were accepted by physicians, and among patients, the interventions were well accepted during the appointments, but compliance with the interventions was not measured. A statistically significant increase in CD4+ T-lymphocyte count in the intervention group was found (260.7 cells/mm(3) [95% CI =175.8-345.6] to 312.0 cells/mm(3) [95% CI =23.5-40.6], P=0.015), which was not observed in the control group. There was no statistical difference between the groups regarding HIV viral load. This study suggests that pharmacist interventions in patients with HIV infection can cause an increase in CD4+ T-lymphocyte counts and a decrease in DRPs, demonstrating the importance of an optimal pharmaceutical care plan.
