Quality of life after pulmonary embolism: Prospective validation of the German version of the PEmb-QoL questionnaire.

BACKGROUND: The Pulmonary Embolism Quality of Life questionnaire (PEmb-QoL) is a 40-item questionnaire to measure health-related quality of life in patients with pulmonary embolism. It covers six 6 dimensions: frequency of complaints, limitations in activities of daily living, work-related problems, social limitations, intensity of complaints, and emotional complaints. Originally developed in Dutch and English, we prospectively validated a German version of the PEmb-QoL. METHODS: A forward-backward translation of the English version of the PEmb-QoL into German was performed. German-speaking consecutive adult patients aged ≥18 years with an acute, objectively confirmed pulmonary embolism discharged from a Swiss university hospital (01/2011-06/2013) were recruited telephonically. Established psychometric tests and criteria were used to evaluate the acceptability, reliability, and validity of the German PEmb-QoL questionnaire. To assess the underlying dimensions, an exploratory factor analysis was performed. RESULTS: Overall, 102 patients were enrolled in the study. The German version of the PEmb-QoL showed a good internal consistency (Cronbach's alpha ranging from 0.72 to 0.96), item-total (0.53-0.95) and inter-item correlations (>0.4), and test-retest reliability (intra-class correlation coefficients 0.59-0.89) for the dimension scores. A moderate correlation of the PEmb-QoL with SF-36 dimension and summary scores (0.21-0.83) indicated convergent validity, while low correlations of PEmb-QoL dimensions with clinical characteristics (-0.16-0.37) supported discriminant validity. The exploratory factor analysis suggested four underlying dimensions: limitations in daily activities, symptoms, work-related problems, and emotional complaints. CONCLUSION: The German version of the PEmb-QoL questionnaire is a valid and reliable disease-specific measure for quality of life in patients with pulmonary embolism.

Newsprint Demand and Supply Scenarios

Diplomityön tavoitteena oli sanomalehtipaperin kysyntään ja tarjontaan vaikuttavien tekijöiden identifiointi ja analysointi. Nämä tekijät käytiin yhteisesti läpi skenaarioiden avulla. Aluksi kuvattiin teollisuuden ala ja esiteltiin tärkeimmät alaa kuvaavat mittarit. Analyysi tehtiin Porterin kilpailuteorian tekijöiden pohjalta. Työssä listattiin yksittäiset tekijät, jotka vaikuttavat sanomalehtipaperin kysyntään ja tarjontaan. Näistä tekijöistä valittiin tärkeimmät ja niiden pohjalta rakennettiin skenaarioita. Skenaariot kuvaavat erilaisia mahdollisia tulevaisuuksia.Kysyntä kuten myös tarjonta on jakautunut epätasaisesti maailmassa. Alueelliset erot ovat hyvinkin merkittäviä. Tästä johtuu laajamittainen kaupankäynti eri alueiden välillä. Käynnissä oleva paperiteollisuuden konsolidoitumisprosessi auttaa vähentämään sanomalehtipaperin hinnan ja tarjonnan heilahtelua. Tämä puolestaan johtuu alan keskittymisestä ja järkevästä kapasiteetin hallinnasta.Diplomityö korostaa sanomalehtipaperin tuottajien vastuuta tarjonnan lisäämisessä. E-median uhkaa tai mahdollisuutta on myös spekuloitu ja kysynnän alueellisen kysynnän kehitystä on analysoitu. Diplomityö antaa ehdotuksia erilaisiksi tulevaisuuden kehitysvaihtoehdoiksi. Sanomalehtipaperin kysyntä tulee kasvamaan maailmanlaajuisesti, tuotanto tulee siirtymään lähemmäksi markkinoita, kaupankäynti Aasiaan tulee kasvamaan ja yrityksen tulevat keskittymään viisaaseen kapasiteetin hallintaan.

Surgery for unruptured arteriovenous malformations of the brain is better than conservative management for selected cases : a prospective cohort study

Object. The aim of this study was to identify patients who are likely to benefit from surgery for unruptured brain arterriovenous malformations (ubAVMs). Methods. The authors' database was interrogated for the risk and outcome of hemorrhage after referral and the out- come from surgery. Furthermore, the outcome from surgery incorporated those cases excluded from surgery because of perceived greater risk (sensitivity analysis). Finally, a comparison was made for the authors' patients between the natural history and surgery. Data were collected for 427 consecutively enrolled patients with ubAVMs in a database that in- cluded patients who were conservatively managed. Kaplan-Meier analysis was performed on patients observed for more than 1 day to determine the risk of hemorrhage. Variables that may influence the risk of first hemorrhage were assessed using Cox proportional hazard regression models and Kaplan-Meier life table analyses from referral until the first occur- rence of the following: hemorrhage, treatment, or last review. The outcome from surgery (leading to a new permanent neurological deficit with last review modified Rankin Scale [mRS] score > 1) was determined. Further sensitivity analy- sis was made to predict risk from surgery for the total ubAVM cohort by incorporating outcomes of surgical cases as well as cases excluded from surgery because of perceived risk, and assuming an adverse outcome for these excluded cases. Results. A total of 377 patients with a ubAVM were included in the analysis of the risk of hemorrhage. The 5-year risk of hemorrhage for ubAVM was 11.5%. Hemorrhage resulted in an mRS score > 1 in 14 cases (88% [95% CI 63%-98%]). Patients with Spetzler-Ponce Class A ubAVMs treated by surgery (n = 190) had a risk from surgery of 1.6% (95% CI 0.3%-4.8%) for a permanent neurological deficit leading to an mRS score > 1 and 0.5% (95% CI< 0.1%-3.2%) for a permanent neurological deficit leading to an mRS score > 2. Patients with Spetzler-Ponce Class B ubAVMs treated by surgery (n = 107) had a risk from surgery of 14.0% (95% CI 8.6%-22.0%) for a permanent neurological deficit leading to an mRS score > 1. Sensitivity analysis of Spetzler-Ponce Class B ubAVMs, including those in patients excluded from surgery, showed that the true risk for surgically eligible patients may have been as high as 15.6% (95% CI 9.9%-23.7%) for mRS score > 1, had all patients who were perceived to have a greater risk experienced an adverse outcome. Patients with Spetzler-Ponce Class C ubAVMs treated by surgery (n = 44) had a risk from surgery of 38.6% (95% CI 25.7%-53.4%) for a permanent neurological deficit leading to an mRS score >1. Sensitivity analysis of Class C ubAVMs, including those harbored by patients excluded from surgery, showed that the true risk for surgically eligible patients may have been as high as 60.9% (95% CI 49.2%-71.5%) for mRS score > 1, had all patients who were perceived to have a greater risk experienced an adverse outcome. Conclusion. Surgical outcomes for Spetzler-Ponce Class ubAVMs are better than those for conservative management.

CoDiab-VD: protocol of a prospective population-based cohort study on diabetes care in Switzerland.

BACKGROUND: Diabetes represents an increasing health burden worldwide. In 2010, the Public Health Department of the canton of Vaud (Switzerland) launched a regional diabetes programme entitled "Programme cantonal Diabète" (PcD), with the objectives to both decrease the incidence of diabetes and improve care for patients with diabetes. The cohort entitled CoDiab-VD emerged from that programme. It specifically aimed at following quality of diabetes care over time, at evaluating the coverage of the PcD within this canton and at assessing the impact of the PcD on care of patients with diabetes. METHODS/DESIGN: The cohort CoDiab-VD is a prospective population-based cohort study. Patients with diabetes were recruited in two waves (autumn 2011--summer 2012) through community pharmacies. Eligible participants were non-institutionalised adult patients (≥ 18 years) with diabetes diagnosed for at least one year, residing in the canton of Vaud and coming to a participating pharmacy with a diabetes-related prescription. Women with gestational diabetes, people with obvious cognitive impairment or insufficient command of French were not eligible. Self-reported data collected, included the following primary outcomes: processes-of-care indicators (annual checks) and outcomes of care such as HbA1C, (health-related) quality of life measures (Short Form-12 Health Survey--SF-12, Audit of Diabetes-Dependent Quality of Life 19--ADDQoL) and Patient Assessment of Chronic Illness Care (PACIC). Data on diabetes, health status, healthcare utilisation, health behaviour, self-management activities and support, knowledge of, or participation to, campaigns/activities proposed by the PcD, and socio-demographics were also obtained. For consenting participants, physicians provided few additional pieces of information about processes and laboratory results. Participants will be followed once a year, via a mailed self-report questionnaire. The core of the follow-up questionnaires will be similar to the baseline one, with the addition of thematic modules adapting to the development of the PcD. Physicians will be contacted every 2 years. DISCUSSION: CoDiab-VD will allow obtaining a broad picture of the care of patients with diabetes, as well as their needs regarding their chronic condition. The data will be used to evaluate the PcD and help prioritise targeted actions. TRIAL REGISTRATION: This study is registered with ClinicalTrials.gov, identifier NCT01902043, July 9, 2013.

Violence en psychiatrie: une recherche prospective au Département Universitaire de Psychiatrie Adulte (DUPA) interrogée à la lumière du modèle cindynique

Le management des risques dans les institutions psychiatriques représente aujourd'hui un challenge majeur pour les cliniciens, les administrateurs et les décideurs politiques. Il pose la question de la formation des équipes au management de la violence et de l'évaluation des patients dans la clinique quotidienne. Cet article fait le lien entre une étude, menée sur un an dans une institution psychiatrique et un modèle de management des risques, le modèle cindynique. Les résultats doivent interroger sur les représentations du phénomène de violence par les différents acteurs, l'appropriation par les équipes d'outils d'évaluation de la dangerosité et sur la communication dans l'équipe pluridisciplinaire et avec le patient.
