Schizofrenie: prevence relapsu a opětovné hospitalizace na psychiatrické klinice po léčbě / Schizophrenia: Prevention of relapse and re-admission to psychiatric hospital after treatment

Aarseth, Erling Becker January 2010 (has links)
It has in this review article been cited several different studies and sources, all concerning the prevention of relapse of schizophrenia and related psychotic disorders; The different approaches to treatment (programs, type of psychotherapy etc.) have been discussed according to evidence based research and randomized controlled trials. Although some explanations have been given about terms used in the literature, as well as some definitions to enable classifications in future studies, it has been focused only on the preventive measures used in schizophrenia; a detailed description of different subgroups of schizophrenia, as well as detailed descriptions of pharmacology in euroleptics is beyond the scope of this article. The recognition of relapse symptoms was first considered and defined, and the different approaches was then discussed; Outpatient treatment plans and relapse prevention plans, as well as the impact of cognitive behavioral therapy and psychotherapy have been discussed in subsequent chapters. In this section, it was especially focused on the ITAREPS program and its impact on the relapse prevention. The role of medications was then defined and supported with clinical studies and trials.

Previsão hidrometeorológica visando sistema de alerta antecipado de cheias em bacias urbanas / Hidrometeorological precipitation forecast for flood early warning systems in urban areas

Juliana Pontes Machado de Andrade 13 September 2006 (has links)
Freqüentemente, a população das áreas metropolitanas é surpreendida pela ocorrência de inundações muito rápidas que causam danos diversos. O sistema de alerta antecipado contra inundações é uma ferramenta que visa minimizar tais impactos. O componente de previsão do sistema será abordado neste trabalho. Tal previsão é feita através de um modelo conceitual de previsão hidrometeorológica de precipitação baseado em equações termodinâmicas e modelo simplificado de física das nuvens seguido de um modelo chuva-vazão. A antecedência proporcionada pelo modelo hidrometeorológico aplicado é de 30 minutos para variáveis de entrada observadas. Este tempo pode ser estendido com a inclusão de estimativas futuras das variáveis de entrada. A calibração do modelo foi feita manualmente com o uso de duas medidas de desempenho, esta etapa pode ser aprimorada em pesquisas futuras. Apesar da simplicidade do modelo hidrometeorológico apresentou-se satisfatório em algumas simulações, conseguindo prever o início das precipitações. / Urban population are often surprised by flash floods which cause several kinds of damages. An early warning system is a tool which aims to minimize such impacts. This work will approach the forecast component of this system. A conceptual hydrometeorological precipitation forecasting model, based on thermodynamics equations and simplified cloud physics, will be used to perform the forecast. Model lead time is 30 minutes for measured inputs, this time can be extended by the use of estimated inputs instead of the measured ones. Calibration was performed manually based on conservation of precipitation volume and its distribution in time. This step can be improved on future researches. In spite of model’s simplicity, some simulations presented satisfactory results, being able to forecast precipitation’s beginning.

Novel approaches to the diagnosis and management of severe acute pancreatitis

Miranda, Charles Joseph January 2016 (has links)
Severe Acute Pancreatitis (SAP) is the rapid onset of inflammation within the pancreatic organ. Unlike the milder form of this illness, SAP is associated with a high mortality and morbidity. No significant reduction in the outcomes of this disease has been made since the implementation of organ supportive management over two decades ago. This is due to difficulties in distinguishing between the milder form of the disease in the early period of the onset of symptoms when clinical intervention is most likely to prevent complications and death. Clinical equipoise exists in the management of one of these complications, namely Abdominal Compartment Syndrome (ACS) as the conventional management of surgery runs contrary to published evidence showing early abdominal surgery deteriorates clinical outcomes. Aims: Validation of the potential use of the Early Warning Score (EWS) as a predictor of SAP. Evaluation of the evidence for recombinant human protein C (Xigris™) in the early treatment of SAP. Determination of the safety profile of Xigris™ when given early in SAP. To determine if surgical management of ACS in SAP is of significant benefit compared to conventional management alone. Methods: Four studies were performed: A prospective observational study assessing the median EWS of patients admitted with acute pancreatitis; a systematic review of published evidence reporting the use of Xigris™ in SAP; a prospective cohort study using a 24 hour infusion of Xigris™ early in patients diagnosed with SAP and a pilot randomized controlled trial of targeted decompression in patients with ACS complicating SAP. Results: The highest EWS values for 130 patients with acute pancreatitis within the first 3 days of admission were not shown to have significant sensitivity and specificity in predicting an unfavourable outcome. A review of the published literature between from January 1985 to January 2011 supported the further investigation of Xigris™ as a treatment for SAP. No significant adverse events or differences in outcomes were evident in 19 patients who received a 24-hour infusion of Xigris™ early in SAP compared to matched historical controls. 22 patients were screened for the development of ACS. No patient developed ACS and consequently no randomization to either treatment arm was possible. Conclusion: With the recent advent of an updated classification system for the severity of acute pancreatitis, further prospective evaluation of the use of EWS in clinical practice is warranted. The results of the Phase 1 clinical trial of Xigris™ didnot reveal significant safety issues that might preclude the further investigation of Xigris™ as a specific therapy early in the onset of SAP. The absence of ACS inpatients with SAP lends support to a theory that ACS may be an epiphenomenon in the course of SAP.

Predictors of financial crises-do we see the same pattern in Sweden?-do we see the same pattern in Sweden? / Indikatorer av finansiella kriser - Ser vi samma mönster i Sverige?

Hedin, Fredrik, Johansson, Jonathan January 2017 (has links)
This paper aims to find macroeconomic and financial variables with ability to predict financial crises. A dataset covering 17 developed countries over the period 1870-2013 have been investigated using a logit model. We found commonly used macroeconomic variables such as terms of trade and consumption to be strong predictors within our sample. Whereas private debt and house prices are frequently found to be strong predictors, we found loans to business to be at least as good in predicting financial crises. Multivariate models are constructed as warning systems and used to analyze Sweden from 1975 up until 2016. The most efficient warning system give a strong signal before the first and moderate signal before the second crisis. In extension, regarding today’s climate the warning system provides no signal, suggesting low current risk. Policy makers can benefit from observing certain variables that are found significant in this study to improve financial stability and reduce socio-economic costs.

It Takes an Institution's Village to Retain a Student: A Comprehensive Look at Two Early Warning System Undergraduate Retention Programs and Administrators' Perceptions of Students' Experiences and the Retention Services they Provide Students in the Early Warning System Retention Programs

Hamilton, Shelly-Ann 03 July 2013 (has links)
Institutions have implemented many campus interventions to address student persistence/retention, one of which is Early Warning Systems (EWS). However, few research studies show evidence of interventions that incorporate noncognitive factors/skills, and psychotherapy/psycho-educational processes in the EWS. A qualitative study (phenomenological interview and document analysis) of EWS at both a public and private 4-year Florida university was conducted to explore EWS through the eyes of the administrators of the ways administrators make sense of students’ experiences and the services they provide and do not provide to assist students. Administrators’ understanding of noncognitive factors and the executive skills subset and their contribution to retention and the executive skills development of at-risk students were also explored. Hossler and Bean’s multiple retention lenses theory/paradigms and Perez’s retention strategies were used to guide the study. Six administrators from each institution who oversee and/or assist with EWS for first time in college undergraduate students considered academically at-risk for attrition were interviewed. Among numerous findings, at Institution X: EWS was infrequently identified as a service, EWS training was not conducted, numerous cognitive and noncognitive issues/deficits were identified for students, and services/critical departments such as EWS did not work together to share students’ information to benefit students. Assessment measures were used to identify students’ issues/deficits; however, they were not used to assess, track, and monitor students’ issues/deficits. Additionally, the institution’s EWS did address students’ executive skills function beyond time management and organizational skills, but did not address students’ psychotherapy/psycho-educational processes. Among numerous findings, at Institution Y: EWS was frequently identified as a service, EWS training was not conducted, numerous cognitive and noncognitive issues/deficits were identified for students, and services/critical departments such as EWS worked together to share students’ information to benefit students. Assessment measures were used to identify, track, and monitor students’ issues/deficits; however, they were not used to assess students’ issues/deficits. Additionally, the institution’s EWS addressed students’ executive skills function beyond time management and organizational skills, and psychotherapy/psycho-educational processes. Based on the findings, Perez’s retention strategies were not utilized in EWS at Institution X, yet were collectively utilized in EWS at Institution Y, to achieve Hossler and Bean’s retention paradigms. Future research could be designed to test the link between engaging in the specific promising activities identified in this research (one-to-one coaching, participation in student success workshops, academic contracts, and tutoring) and student success (e.g., higher GPA, retention). Further, because this research uncovered some concern with how to best handle students with physical and psychological disabilities, future research could link these same promising strategies for improving student performance for example among ADHD students or those with clinical depression.

Evaluation des systèmes d'intelligence épidémiologique appliqués à la détection précoce des maladies infectieuses au niveau mondial. / Evaluation of epidemiological intelligence systems applied to the early detection of infectious diseases worldwide.

Barboza, Philippe 16 December 2014 (has links)
Nos travaux ont démontré les performances des systèmes d’intelligence épidémiologique en matière de détection précoce des évènements infectieux au niveau mondial, la valeur ajoutée spécifique de chaque système, la plus grande sensibilité intrinsèque des systèmes modérés et la variabilité du type de source d’information utilisé. La création d’un système virtuel combiné intégrant le meilleur résultat des sept systèmes a démontré les gains en termes de sensibilité et de réactivité, qui résulterait de l’intégration de ces systèmes individuels dans un supra-système. Ils ont illustrés les limites de ces outils et en particulier la faible valeur prédictive positive des signaux bruts détectés, la variabilité les capacités de détection pour une même pathologie, mais également l’influence significative jouée par le type de pathologie, la langue et la région de survenue sur les capacités de détection des évènements infectieux. Ils ont établis la grande diversité des stratégies d’intelligence épidémiologique mises en œuvre par les institutions de santé publique pour répondre à leurs besoins spécifiques et l’impact de ces stratégies sur la nature, l’origine géographique et le nombre des évènements rapportés. Ils ont également montré que dans des conditions proches de la routine, l’intelligence épidémiologique permettait la détection d’évènements infectieux en moyenne une à deux semaines avant leur notification officielle, permettant ainsi d’alerter les autorités sanitaires et d’anticiper la mise en œuvre d’éventuelles mesures de contrôle. Nos travaux ouvrent de nouveaux champs d’investigations dont les applications pourraient être importantes pour les utilisateurs comme pour les systèmes. / Our work demonstrated the performance of the epidemic intelligence systems used for the early detection of infectious diseases in the world, the specific added value of each system, the greater intrinsic sensitivity of moderated systems and the variability of the type information source’s used. The creation of a combined virtual system incorporating the best result of the seven systems showed gains in terms of sensitivity and timeliness that would result from the integration of these individual systems into a supra-system. They have shown the limits of these tools and in particular: the low positive predictive value of the raw signals detected, the variability of the detection capacities for the same disease, but also the significant influence played by the type of pathology, the language and the region of occurrence on the detection of infectious events. They established the wide variety of epidemic intelligence strategies used by public health institutions to meet their specific needs and the impact of these strategies on the nature, the geographic origin and the number of events reported. As well, they illustrated that under conditions close to the routine, epidemic intelligence permitted the detection of infectious events on average one to two weeks before their official notification, hence allowing to alert health authorities and therefore the anticipating the implementation of eventual control measures. Our work opens new fields of investigation which applications could be important for both users systems.

Sjuksköterskors erfarenheter av att använda bedömningsinstrumentet NEWS : en integrerad litteraturöversikt / Nurses' experiences of using the assessment tool NEWS : an integrated literature review

Fjällborg, Jenny, Johansson, Susanne January 2020 (has links)
National Early Warning Score (NEWS) är ett bedömningsinstrument som används inom vården för att upptäcka och varna när en patient blir kraftigt försämrad. Syftet med litteraturöversikten var att sammanställa kunskap om sjuksköterskors erfarenheter av att använda bedömningsinstrumentet NEWS. En integrerad litteraturöversikt genomfördes där 12 vetenskapliga artiklar togs ut efter en systematisk litteratursökning i PubMed och CINAHL. Av dessa var det sex med kvalitativ metod, fyra kvantitativ metod och två mixad metod, som granskades och analyserades. Analysen resulterade i fyra kategorier. Dessa var ”NEWS användes av sjuksköterskan för att observera, bedöma och planera vård”, ”NEWS kunde både vara ett stöd och skapa merarbete”, ”NEWS förbättrade kommunikationen med andra kollegor” och ” NEWS kunde främja sjuksköterskan i sin profession”. Slutsatserna som drogs var att sjuksköterskorna ansåg NEWS som användbart vid att uppfatta en patients försämring, instrumentet användes även som ett sätt att stödja en egen klinisk bedömning. Sjuksköterskorna ansåg att NEWS behövde anpassas för olika sjukdomstillstånd eftersom falska höga värden ledde till onödiga kontroller och larmutmattning. Kommunikationen mellan kollegor blev bättre och sjuksköterskorna fick stöd och bättre respons när vitalparametrar kommunicerades. Sjuksköterskorna ansåg att NEWS ökade fokuset på vitalparametrar vilket ledde till ökad kunskap om avvikelser samt stimulerade till egna bedömningar. Författarna anser att det finns behov av att arbeta särskilt med kommunikationsmetoder som införlivas med NEWS, där alla parter i vårdkedjan förstår instrumentets relevans. Detta kan förslagsvis göras i samband vid implementering av NEWS med tydliga riktlinjer kring bedömnings-instrumentet, hur det ska användas och varför.
