Clinically diagnosed childhood asthma and follow-up of symptoms in a Swedish case control study

BACKGROUND: Childhood asthma has risen dramatically not only in the western societies and now forms a major and still increasing public health problem. The aims of this study were to follow up at the age of ten the patterns of asthma symptoms and associations among children with a clinically diagnosed asthma in a sizeable urban-rural community and to in compare them with demographic controls using a standardised questionnaire. METHODS: In a defined region in Sweden with a population of about 150 000 inhabitants, all children (n = 2 104) born in 1990 were recorded. At the age of seven all primary care and hospital records of the 1 752 children still living in the community were examined, and a group of children (n = 191) was defined with a well-documented and medically confirmed asthma diagnosis. At the age of ten, 86 % of these cases (n = 158) and controls (n = 171) completed an ISAAC questionnaire concerning asthma history, symptoms and related conditions. RESULTS: Different types of asthma symptoms were highly and significantly over-represented in the cases. Reported asthma heredity was significantly higher among the cases. No significant difference in reported allergic rhinitis or eczema as a child was found between cases and controls. No significant difference concerning social factors or environmental exposure was found between case and controls. Among the control group 4.7 % of the parents reported that their child actually had asthma. These are likely to be new asthma cases between the age of seven and ten and give an estimated asthma prevalence rate at the age of ten of 15.1 % in the studied cohort. CONCLUSION: A combination of medical verified asthma diagnosis through medical records and the use of self-reported symptom through the ISAAC questionnaire seem to be valid and reliable measures to follow-up childhood asthma in the local community. The asthma prevalence at the age of ten in the studied birth cohort is considerably higher than previous reports for Sweden. Both the high prevalence figure and allowing the three-year lag phase for further settling of events in the community point at the complementary roles of both hospital and primary care in the comprehensive coverage and control of childhood asthma in the community

Hepatitis C infection: eligibility for antiviral therapies

peer reviewedBackground Current treatments of chronic hepatitis C virus (HCV) are effective, but expensive and susceptible to induce significant side effects. Objectives To evaluate the proportion of HCV patients who are eligible for a treatment. Methods In a database comprising 1726 viraemic HCV patients, the files of 299 patients who presented to the same hepatologist for an initial appointment between 1996 and 2003 were reviewed. Results Patients' characteristics were age 43.1 +/- 15.6 years, 53% male and 92% Caucasian. The main risk factors were transfusion (43%) and drug use (22%). Genotypes were mostly genotype 1 (66%), genotype 3 (12%) and genotype 2 (10%). These characteristics were not different from those of the whole series of 1726 patients. A total of 176 patients (59%) were not treated, the reasons for non-treatment being medical contraindications (34%), non-compliance (25%) and normal transaminases (24%). In addition, 17% of patients declined therapy despite being considered as eligible, mainly due to fear of adverse events. Medical contraindications were psychiatric (27%), age (22%), end-stage liver disease (15%), willingness for pregnancy (13%), cardiac contraindication (7%) and others (16%). Only 123 patients (41%) were treated. A sustained viral response was observed in 41%. The treatment was interrupted in 16% for adverse events. Conclusions The majority of HCV patients are not eligible for treatment. This implies that, with current therapies, only 17% of patients referred for chronic HCV become sustained responders. Some modifications of guidelines could extend the rate of treatment (patients with normal transaminases), but an important barrier remains the patients' and the doctors' fear of adverse events

Scoping Review: Digital mental health interventions for children and adolescents affected by war

Objective Over 200 million children and adolescents live in countries affected by violent conflict, are likely to have complex mental health needs, and struggle to access traditional mental health services. Digital mental health interventions have the potential to overcome some of the barriers in accessing mental health support. We performed a scoping review to map existing digital mental health interventions relevant for children and adolescents affected by war, examine the strength of the evidence base, and inform the development of future interventions. Method Based on a pre-registered strategy, we systematically searched MEDLINE, Embase, Global Health, APA PsychInfo, and Google Scholar from the creation of each database to 30th September 2022, identifying k=6,843 studies. Our systematic search was complemented by extensive consultation with experts from the GROW Network. Results The systematic search identified 6 relevant studies: one evaluating digital mental health interventions for children and adolescents affected by war and five for those affected by disasters. Experts identified 35 interventions of possible relevance. The interventions spanned from universal prevention to specialist-guided treatment. Most interventions directly targeted young people and parents/carers and were self-guided. A quarter of the interventions were tested through randomized controlled trials. Because most interventions were not culturally or linguistically adapted to relevant contexts, their implementation potential was unclear. Conclusion There is very limited evidence for the use of digital mental health interventions for children and adolescents affected by war at present. The review provides a framework to inform the development of new interventions

Estudo da psico-manutenção da Asma: as cognições como preditoras de emoções e comportamentos problemáticos associados à Asma

Numa amostra de 50 doentes asmáticos hospitalizados ou em regime de consulta externa, investigou-se a associação entre as cognições disfuncionais associadas à Asma e outras variáveis psicológicas (emoções e comportamentos) tradicionalmente estudadas no âmbito dos modelos cognitivo-comportamentais, através de instrumentos de medida dessas variáveis específicos para a doença asmática. Os resultados encontrados sugerem que as cognições disfuncionais associadas à Asma são preditoras de comportamentos/emoções problemáticos que ocorrem antes, durante e depois das crises asmáticas. Sugerem-nos ainda que as cognições disfuncionais são preditoras de maiores níveis de sintomatologia “pânico/medo” e de atitudes negativas face à doença asmática e ao seu tratamento
