The third paradigm provides an opportunity to look beyond any dichotomy between "standardized" versus "real-life" characteristics of the health care system and study designs. Namely, future research will determine whether the identification of these contextual factors can help to best design randomized controlled trials that provide better estimates of drugs' effectiveness.
This prospective observational cohort study aimed to explore the clinical features of incident immune thrombocytopenia in adults and predictors of outcome, while determining if a family history of autoimmune disorder is a risk factor for immune thrombocytopenia. All adults, 18 years of age or older, recently diagnosed with immune thrombocytopenia were consecutively recruited across 21 hospital centers in France. Data were collected at diagnosis and after 12 months. Predictors of chronicity at 12 months were explored using logistic regression models. The association between family history of autoimmune disorder and the risk of developing immune thrombocytopenia was explored using a conditional logistic regression model after matching each case to 10 controls. One hundred and forty-three patients were included: 63% female, mean age 48 years old (Standard Deviation=19), and 84% presented with bleeding symptoms. Median platelet count was 10×10(9)/L. Initial treatment was required in 82% of patients. After 12 months, only 37% of patients not subject to disease-modifying interventions achieved cure. The sole possible predictor of chronicity at 12 months was a higher platelet count at baseline [Odds Ratio 1.03; 95%CI: 1.00, 1.06]. No association was found between outcome and any of the following features: age, sex, presence of either bleeding symptoms or antinuclear antibodies at diagnosis. Likewise, family history of autoimmune disorder was not associated with incident immune thrombocytopenia. Immune thrombocytopenia in adults has been shown to progress to a chronic form in the majority of patients. A lower platelet count could be indicative of a more favorable outcome.
Dropout rates from inpatient treatment for eating disorders are very high and have a negative impact on outcome. The purpose of this study was to identify personality factors predictive of dropout from hospitalization. A total of 64 adult patients with anorexia nervosa consecutively hospitalized in a specialized unit were included; 19 patients dropped out. The dropout group and the completer group were compared for demographic variables, clinical features, personality dimensions, and personality disorders. There was no link between clinical features and dropout, and among demographic variables, only age was associated with dropout. Personality factors, comorbidity with a personality disorder and Self-transcendence dimension, were statistically predictive of premature termination of hospitalization. In a multivariate model, these two factors remain significant. Personality traits (Temperament and Character Inventory personality dimension and comorbid personality disorder) are significantly associated with dropout from inpatient treatment for anorexia nervosa. Implications for clinical practice, to diminish the dropout rate, will be discussed.
BackgroundAnorexia nervosa is a severe psychiatric disorder mainly affecting women. Its treatment is long and accepted with much difficulty, in particular in-patient treatment.AimsTo describe the subjective motives of women with anorexia nervosa for requesting in-patient admission, from a qualitative analysis of application letters.MethodsParticipants were adult women (18 years and older) with anorexia nervosa who were admitted as in-patients in a referral hospital unit in France from January 2008 to December 2010. The application letters, prerequisites to admission, were studied by the interpretative phenomenological method of content analysis.Results63 letters have been analysed, allowing the identification of six themes related to requests for in-patient care: loss of control of behaviour, and of thoughts, mental exhaustion, isolation, inner struggle and fear of recovery.ConclusionsRequests for in-patient admission were motivated by very personal, subjective experiences, unrelated to medical reasons for admission. These results may help improve pre-admission motivational work with individuals, by basing it on their subjective experience.
To describe the clinical and economic burden of severe asthma in France over 12 months. Methods: Data were retrieved from the observational, prospective "Cohorte Obstruction Bronchique et Asthme" (COBRA) cohort, which has enrolled nearly 1000 asthma patients since 2007 from throughout France. Patients undergoing treatment with GINA step-4 or 5 medications uninterruptedly for 12 months (thus defining "severe asthma") were identified and their clinical data used to describe the clinical burden of asthma (exacerbations, symptoms outside exacerbations, and level of asthma control). Patients' utilization of healthcare resources was described and used to estimate the direct medical costs incurred to treat severe asthma. Results: 155 patients were included in the present study. Over the 12-month period of interest, 128 (83%) patients experienced at least one asthma exacerbation, 22 (14%) patients were hospitalized for asthma, 133 (86%) patients experienced continuous symptoms outside exacerbations, and 77 (50%) patients experienced important limitations in daily life activities. The median number of asthma-related drugs used was 4. The mean estimated annual asthma-related cost was 8,222 euros (standard deviation, SD = 11,886), including 7,229 euros (SD = 11,703) for controller medications. Conclusion: Symptoms outside exacerbation periods are highly prevalent in severe asthma patients, for whom the main driver of medical costs is controller medication.
Background: The majority of patients with chronic obstructive pulmonary disease (COPD) suffer from comorbid cardiovascular (CV) disease. Accumulating evidence suggests a temporal association between COPD exacerbations and acute CV events, possibly due to lung hyperinflation, increased hypoxemia and systemic inflammation. The aims of the study were to estimate the risk of (1) acute CV events [acute myocardial infarction (AMI), CV-related death] or stroke in the months following a COPD exacerbation and (2) COPD exacerbation in the months following an acute CV event. Methods: A systematic literature review of observational studies published since 2000 was conducted by searching literature databases (Medline and Embase). Studies were eligible if conducted in adults with COPD, exposed to either COPD exacerbation or acute CV events, with outcomes of acute CV events or COPD exacerbation reported. Studies were appraised for relevance, bias and quality. Meta-analyses, using random-effect models, were performed for each outcome of interest, thus providing a pooled relative risk (RR) and its 95% confidence interval. Results: Eight studies were identified, of which seven were used for the meta-analyses examining the risk of CV events 1–3 months after an exacerbation compared with none. For stroke (six studies), RR was 1.68 (95% CI = 1.19–2.38). For AMI (six studies), RR was 2.43 (95% CI = 1.40–4.20). No studies exploring risk of exacerbation following an acute CV event were identified. Conclusion: This meta-analysis identified a markedly increased risk of stroke or AMI within a relatively short period of time following a COPD exacerbation. Although the underlying mechanisms are not fully elucidated, patients with COPD should be monitored for risk of CV outcomes after exacerbations. In addition, preventing exacerbations may decrease the risk of subsequent acute CV events. Registration: The study protocol was published via PROSPERO: International Prospective Register of Systematic Reviews (#CRD42020211055).
In routine clinical practice, the decision to apply a watchful waiting strategy seems to be driven by platelet counts even in the absence of bleeding symptoms, resulting in treatment being initiated in more than 80% of the children surveyed. Overall, younger children with ITP showed good prognosis, with lower platelet counts and, to a lesser extent, male gender predicting more favorable outcomes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
