Consensus statement on the diagnosis, management, and treatment of angioedema mediated by Bradykinin. Part. II: treatment, follow-up, and special situations

Background: There are no previous Spanish guidelines or consensus statements on bradykinin-induced angioedema. Aim: To draft a consensus statement on the management and treatment of angioedema mediated by bradykinin in light of currently available scientifi c evidence and the experience of experts. This statement will serve as a guideline to health professionals. Methods: The consensus was led by the Spanish Study Group on Bradykinin-Induced Angioedema, a working group of the Spanish Society of Allergology and Clinical Immunology. A review was conducted of scientifi c papers on different types of bradykinin-induced angioedema (hereditary and acquired angioedema due to C1 inhibitor defi ciency, hereditary angioedema related to estrogens, angioedema induced by angiotensin-converting enzyme inhibitors). Several discussion meetings were held to reach the consensus. Results: Treatment approaches are discussed, and the consensus reached is described. Specifi c situations are addressed, namely, pregnancy, contraception, travelling, blood donation, and organ transplantation. Conclusions: A review of and consensus on treatment of bradykinin-induced angioedema is presentedIntroducción: No existen guías previas españolas sobre el manejo del angioedema mediado por bradicinina. Objetivos: Alcanzar un consenso sobre el manejo y tratamiento del angioedema mediado por bradicinina a la luz de la evidencia científi ca disponible y la experiencia de los expertos, que sirva como guía para los profesionales de la salud. Métodos: SGBA/GEAB, un grupo de trabajo de la SEAIC dirigió el consenso. Se realizó una revisión de los documentos científi cos publicados sobre los diferentes tipos de angioedema mediado por bradicinina [angioedema hereditario o adquirido por defi ciencia de inhibidor de la C1 esterasa, angioedema hereditario relacionado con estrógenos (AEH tipo III, AEH-FXII), angioedema inducido por IECA (inhibidores del enzima convertidor de angiotensina]. Hubo varias reuniones del SGBA/GEAB para alcanzar el consenso. Resultados: Se revisan y discuten los diferentes tratamientos disponibles y se describe el consenso alcanzado.

Conclusiones: Se presenta una revisión del tratamiento del angioedema mediado por bradicinina y un consenso sobre su tratamiento en EspañaDr. Teresa Caballero is a researcher with the Hospital La Paz Health Research Institute (IdiPaz) program for promoting research activities (2009

Angioedema severity and impact on quality of life: Chronic histaminergic angioedema versus chronic spontaneous urticaria

Histamine-mediated angioedema is the most frequent form of angioedema. It is classified as idiopathic histaminergic acquired angioedema (IH-AAE)1 when allergies and other causes have been excluded and a positive treatment response to antihistamines, corticosteroids, or omalizumab has been reported. Idiopathic histaminergic acquired angioedema may occur in isolation, when it is termed chronic histaminergic angioedema (CHA), or it may be associated with wheals in chronic spontaneous urticaria angioedema (CSU-AE). The term CHA is equivalent to IH-AAE and mast cell-mediated angioedema. However, this term reflects the chronic and recurrent course of the disease. Therefore, we propose that the term CHA be internationally discussed in the following guidelines. Chronic spontaneous urticaria is classically characterized by the presence of recurrent episodes of wheals (hives) with or without angioedema for at least 6 weeks.2 Chronic histaminergic angioedema is typically considered a subtype of CSU without wheals. However, a recent study3 found several features that differentiate CHA from CSU, which suggests that CHA is a separate entity. Quality of life (QoL) studies specifically for CHA patients have not been performed, and their QoL has been assessed only in the context of CSU-AE

Desafios da integração nos novos arranjos institucionais de políticas públicas no Brasil

Resumo O Governo Federal brasileiro tem experimentado arranjos institucionais que tem como objetivo construir políticas públicas efetivas em um contexto territorial complexo. Neles há dois eixos centrais: (i) a tentativa de articular temáticas intersetoriais e (ii) a construção de modelos de gestão de políticas públicas com coordenação entre os entes federativos e a sociedade civil. Este artigo analisa como novos arranjos institucionais consideram o papel dos territórios. A análise está estruturada em duas questões centrais: (a) qual a centralidade dada à concepção de território e em que medida ele desempenha papel ativo ou passivo no desenho do arranjo; (b) que fatores poderiam explicar contornos do arranjo institucional e como a dimensão territorial se materializa neles. O artigo analisa três arranjos: Plano Brasil Sem Miséria; Programa de Aceleração do Crescimento; Programa Territórios da Cidadania. As análises baseadas em documentos oficiais dos programas visam compreender, a partir de sua estrutura de funcionamento, como se dão questões como intersetorialidade, relações federativas e concepção de território. Analisando os programas, percebe-se que, ainda que em graus variados, há mais justaposição do que integração de políticas públicas, e que neles os territórios – entendido como os lócus de implementação das políticas e as forças sociais nele presentes – não ocupam uma posição ativa, revelando-se meros repositórios de investimentos. Como consequência, essa fragilidade, observada tanto na dupla integração desejada como na articulação territorial, é algo que resulta em perda de eficiência dos investimentos e em comprometimento dos resultados. Esses limites se devem, em grande medida, ao peso da cultura setorial que permeia os gestores e o comportamento das forças sociais, associado a uma cultura institucional de privilégio dos resultados alcançáveis em curto prazo. Esses aspectos, por sua vez, concretizam-se tanto nas normas que regulamentam os arranjos como no leque de agentes envolvidos. Em termos teóricos essa hipótese se afasta das análises que tomam os arranjos meramente sob o ângulo administrativo ou de gestão e se aproxima das abordagens institucionalistas, para as quais não se pode analisar os arranjos institucionais isolados do ambiente institucional do qual são, a um só tempo, parte e expressão

Human resources: the Cinderella of health sector reform in Latin America

Human resources are the most important assets of any health system, and health workforce problems have for decades limited the efficiency and quality of Latin America health systems. World Bank-led reforms aimed at increasing equity, efficiency, quality of care and user satisfaction did not attempt to resolve the human resources problems that had been identified in multiple health sector assessments. However, the two most important reform policies – decentralization and privatization – have had a negative impact on the conditions of employment and prompted opposition from organized professionals and unions. In several countries of the region, the workforce became the most important obstacle to successful reform. This article is based on fieldwork and a review of the literature. It discusses the reasons that led health workers to oppose reform; the institutional and legal constraints to implementing reform as originally designed; the mismatch between the types of personnel needed for reform and the availability of professionals; the deficiencies of the reform implementation process; and the regulatory weaknesses of the region. The discussion presents workforce strategies that the reforms could have included to achieve the intended goals, and the need to take into account the values and political realities of the countries. The authors suggest that autochthonous solutions are more likely to succeed than solutions imported from the outside

Epigenetic remodelling licences adult cholangiocytes for organoid formation and liver regeneration.

Following severe or chronic liver injury, adult ductal cells (cholangiocytes) contribute to regeneration by restoring both hepatocytes and cholangiocytes. We recently showed that ductal cells clonally expand as self-renewing liver organoids that retain their differentiation capacity into both hepatocytes and ductal cells. However, the molecular mechanisms by which adult ductal-committed cells acquire cellular plasticity, initiate organoids and regenerate the damaged tissue remain largely unknown. Here, we describe that ductal cells undergo a transient, genome-wide, remodelling of their transcriptome and epigenome during organoid initiation and in vivo following tissue damage. TET1-mediated hydroxymethylation licences differentiated ductal cells to initiate organoids and activate the regenerative programme through the transcriptional regulation of stem-cell genes and regenerative pathways including the YAP-Hippo signalling. Our results argue in favour of the remodelling of genomic methylome/hydroxymethylome landscapes as a general mechanism by which differentiated cells exit a committed state in response to tissue damage.RCUK Cancer Research UK ERC H2020 Wellcome Trus

Systematic review of quality of life and functional outcomes in randomized placebo-controlled studies of medications for attention-deficit/hyperactivity disorder

Children, adolescents and adults with attention-deficit/hyperactivity disorder (ADHD) experience functional impairment and poor health-related quality of life (HRQoL) in addition to symptoms of inattention/hyperactivity-impulsivity. To synthesize qualitatively the published evidence from randomized, double-blind, placebo-controlled trials of the effectiveness of pharmacotherapy on functional impairment or HRQoL in patients with ADHD, a systematic PubMed searching and screening strategy was designed to identify journal articles meeting pre-specified criteria. Post hoc analyses and meta-analyses were excluded. HRQoL outcomes, functional outcomes and the principal ADHD symptom-based outcome were extracted from included studies. An effect size of 0.5 versus placebo was used as a threshold for potential clinical relevance (unreported effect sizes were calculated when possible). Of 291 records screened, 35 articles describing 34 studies were included. HRQoL/functioning was usually self-rated in adults and proxy-rated in children/adolescents. Baseline data indicated substantial HRQoL deficits in children/adolescents. Placebo-adjusted effects of medication on ADHD symptoms, HRQoL and functioning, respectively, were statistically or nominally significant in 18/18, 10/12 and 7/9 studies in children/adolescents and 14/16, 9/11 and 9/10 studies in adults. Effect sizes were ≥0.5 versus placebo for symptoms, HRQoL and functioning, respectively, in 14/16, 7/9 and 4/8 studies in children/adolescents; and 6/12, 1/6 and 1/8 studies in adults. Effect sizes were typically larger for stimulants than for non-stimulants, for symptoms than for HRQoL/functioning, and for children/adolescents than for adults. The efficacy of ADHD medication extends beyond symptom control and may help reduce the related but distinct functional impairments and HRQoL deficits in patients with ADHD

Alcohol consumption and risky sexual practices: the pattern of nursing students from the Spanish University

OBJECTIVE: to determine the prevalence of substance abuse and unsafe sexual practices and to analyze the relationship between them, in nursing students at the University of Seville. METHOD: quantitative methodological approach with a descriptive cross-sectional design. The population was composed of first year nursing students in the University of Seville, during the academic year 2010-2011 (N=510), with consecutive opportunistic sampling composed of students who attended class on the scheduled day (n=291). RESULTS: a high prevalence of alcohol consumption, and increased likelihood of not using protective measures during sexual practices when alcohol had been consumed, was present. CONCLUSION: these findings are consistent with those obtained in the same population in Brazil, and highlight the need to strengthen in the nursing curriculum, the transverse axis related to the prevention of substance abuse, especially alcohol

Longitudinal association between motor and obsessive compulsive symptoms in patients with psychosis and their unaffected siblings

Little is known about the co-prevalence of obsessive compulsive symptoms (OCS) and motor symptoms in patients with psychotic disorders. Cross-sectional associations between OCS and motor symptoms were assessed at baseline and at 3years follow-up in patients (n=726) with psychotic disorders and in their unaffected siblings (n=761) from the Dutch Genetic Risk and Outcome of Psychosis (GROUP) study. Furthermore, longitudinal associations between changes in OCS and motor symptoms were evaluated. At baseline, OCS was not associated with any motor symptom (akathisia, dyskinesia, parkinsonism or dystonia) in patients. At follow-up, patients with OCS reported significantly more akathisia. Dividing the patients into four groupsno OCS, OCS remission with OCS only at baseline, OCS de novo with OCS only at follow-up and a persistent OCS grouprevealed that the OCS de novo group already reported more akathisia at baseline compared to the no-OCS group. At follow-up, both the OCS de novo and the persistent OCS group reported more akathisia. These results remained significant after correcting for relevant confounders clozapine, GAF score, PANSS-negative score and IQ. Motor symptoms at baseline were significantly associated with OCS at follow-up, but not the other way around. In siblings, OCS at baseline was associated with akathisia, but this association was lost at follow-up. Results suggest that motor symptoms might precede co-occurring OCS in patients with psychotic disorders. However, no inference can be made about causality, and further prospective research is needed to investigate this assumption
