Adolescents' Views on Seeking Help for Emotional and Behavioral Problems: A Focus Group Study

This study aimed to get insight into adolescents' views on help-seeking for emotional and behavioral problems. Fourteen focus groups were conducted. Two vignettes, depicting one healthy adolescent with few issues and one adolescent with severe psychosocial problems, were used to structure the focus groups. The focus groups were framed within a youth help-seeking model. Adolescents (mean age of 15.0 years) generally reported seeking help from friends or the internet for mild issues and from a person they trust like a parent or school mentor, for more severe problems. Adolescents correctly recognized the issues in vignette one as surmountable and the problems in vignette two as severe. A bond of trust with a help source was regarded as the main facilitator for the decision to seek help. Adolescents reported a preference for help sources who clearly displayed their expertise for the issue at hand and for informal help-sources, particularly friends

Busulfan exposure associated with event-free survival in children after allogeneic haematopoietic stem cell transplantation: A retrospective multicenter cohort study

Busulfan exposure associated with event-free survival in children after allogeneic haematopoietic stem cell transplantation: A retrospective multicenter cohort study OBJECTIVE To determine the relationship between busulfan cumulative area under the curve (AUC] and event-free survival lEFS] in children undergoing allogeneic haematopoietic stem cell transplantation (alloHCT). DESIGN Retrospective, multicenter cohort study. METHODS Children who underwent alloHCT in 15 different centres worldwide were included in this study (2000-20131. Participants had to be on intravenous busulfan and pharmacokinetic samples had to be available. Exposure of interest was the cumulative AUC of busulfan, and primary outcome was EFS (time to graft failure, relapse or all-cause mortality). Cox regression models were used to derive relative risks (RR), and the optimal busulfan AUC level was estimated using propensity adjusted Weibull models. RESULTS A total of 674 subjects (41[%] malignant, 59[%] non- malignant) with a median age of 4.5 years (interquartile range 1.4-10.7 years) were included in the analysis. We observed a significant U-shaped relationship between busulfan cumulative AUC and EFS (P = 0.011). The optimal target was estimated at 90 mgh/L (78-101 mgh/L), and was independent of any of the investigated patient characteristics. An AUC below the target increased the risk of graft failure and relapse (relative risk 1.75, P = 0.004), while transplant-related mortality was more pronounced when the AUC was too high (relative risk 2.99, P <0.0011. CONCLUSION This is the largest study on the relationship between busulfan and clinical outcomes in children undergoing alloHCT. Our results strongly advocate the use of therapeutic drug monitoring of busulfan, using 90 mg-h/L (78-101 mg h/L) as a target

Rabbit ATG/ATLG in preventing graft-versus-host disease after allogeneic stem cell transplantation: consensus-based recommendations by an international expert panel

This collaborative initiative aimed to provide recommendations on the use of polyclonal antithymocyte globulin (ATG) or anti-T lymphocyte globulin (ATLG) for the prevention of graft-versus-host disease (GvHD) after allogeneic hematopoietic stem cell transplantation (HSCT). A comprehensive review of articles released up to October, 2018 was performed as a source of scientific evidence. Fourteen clinically relevant key questions to the domains indication, administration, and post-transplant management were developed and recommendations were produced using the Delphi technique involving a Panel of 14 experts. ATG/ATLG was strongly recommended as part of myeloablative conditioning regimen prior to matched or mismatched unrelated bone marrow or peripheral blood allogeneic HSCT in malignant diseases to prevent severe acute and chronic GvHD. ATG/ATLG was also recommended prior to HLA-identical sibling peripheral HSCT with good but lesser bulk of evidence. In reduced intensity or nonmyeloablative conditioning regimens, ATG/ATLG was deemed appropriate to reduce the incidence of acute and chronic GvHD, but a higher risk of relapse should be taken into account. Recommendations regarding dose, application, and premedication were also provided as well as post-transplant infectious prophylaxis and vaccination. Overall, these recommendations can be used for a proper and safe application of polyclonal ATG/ATLG to prevent GvHD after allogeneic HSCT

Enzyme replacement therapy and/or hematopoietic stem cell transplantation at diagnosis in patients with mucopolysaccharidosis type I: results of a European consensus procedure

<p>Abstract</p> <p>Background</p> <p>Mucopolysaccharidosis type I (MPS I) is a lysosomal storage disorder that results in the accumulation of glycosaminoglycans causing progressive multi-organ dysfunction. Its clinical spectrum is very broad and varies from the severe Hurler phenotype (MPS I-H) which is characterized by early and progressive central nervous system (CNS) involvement to the attenuated Scheie phenotype (MPS I-S) with no CNS involvement. Indication, optimal timing, safety and efficacy of the two available treatment options for MPS I, enzyme replacement therapy (ERT) and hematopoietic stem cell transplantation (HSCT), are subject to continuing debate. A European consensus procedure was organized to reach consensus about the use of these two treatment strategies.</p> <p>Methods</p> <p>A panel of specialists, including 8 specialists for metabolic disorders and 7 bone marrow transplant physicians, all with acknowledged expertise in MPS I, participated in a modified Delphi process to develop consensus-based statements on MPS I treatment. Fifteen MPS I case histories were used to initiate the discussion and to anchor decisions around either treatment mode. Before and at the meeting all experts gave their opinion on the cases (YES/NO transplantation) and reasons for their decisions were collected. A set of draft statements on MPS I treatment options composed by a planning committee were discussed and revised during the meeting until full consensus.</p> <p>Results</p> <p>Full consensus was reached on several important issues, including the following: 1) The preferred treatment for patients with MPS I-H diagnosed before age 2.5 yrs is HSCT; 2) In individual patients with an intermediate phenotype HSCT may be considered if there is a suitable donor. However, there are no data on efficacy of HSCT in patients with this phenotype; 3) All MPS I patients including those who have not been transplanted or whose graft has failed may benefit significantly from ERT; 4) ERT should be started at diagnosis and may be of value in patients awaiting HSCT.</p> <p>Conclusions</p> <p>This multidisciplinary consensus procedure yielded consensus on the main issues related to therapeutic choices and research for MPS I. This is an important step towards an international, collaborative approach, the only way to obtain useful evidence in rare diseases.</p

Encounters with the moral economy of water: convergent evolution in Valencia

[EN] This article presents the results of comparative fieldwork on the huerta of Valencia in Spain, a successful community-managed irrigation system of medium scale, one governed collectively by thousands of small farmers organized into 10 autonomous but highly interdependent irrigator groups. The study tested a model identified previously in research on successful systems of much smaller scale in Peru, a set of principles of operation that, when affirmed by farmers and obeyed as collective-choice rules, interact to create equity among water rights and transparency in water use in an unusual way. The authors show that a nearly identical set are at work in all 10 communities of Valencia, revealing the unique manner in which these work together to promote successful and sustainable cooperation, both within and between the user groups, and arguing that their presence in Spain and the Andes is indicative, not of diffusion from one continent to another, but of independent invention. These principles together laid the foundations for separate Andean and Islamic hydraulic traditions, which were often manifested locally in robust and equitable systems of the same general type, here called the moral economy of water. This kind of communal system appears to have emerged repeatedly, and often independently, in a great many other locales and settings throughout the world; its adaptive dynamics are shown to be of great relevance to small farmers today as they face the growing scarcity of water being induced by population growth and by climate change.Trawick, P.; Ortega Reig, MV.; Palau-Salvador, G.

A risk factor analysis of outcomes after unrelated cord blood transplantation for children with Wiskott-Aldrich syndrome

Wiskott-Aldrich syndrome is a severe X-linked recessive immune deficiency disorder. A scoring system of Wiskott-Aldrich syndrome severity (0.5-5) distinguishes 2 phenotypes: X-linked thrombocytopenia and classic Wiskott-Aldrich syndrome. Hematopoietic cell transplantation is curative for Wiskott-Aldrich syndrome, however the use of unrelated umbilical cord blood transplantation has seldom been described. We analyzed umbilical cord blood transplantation outcomes for 90 patients. Median age at umbilical cord blood transplantation was 1.5 years. Patients were classified according to clinical scores (2 (23%), 3 (30%), 4 (23%) and 5 (19%)). Most patients received HLA mismatched umbilical cord blood transplantation and myeloablative conditioning with anti-thymocyte globulin. Cumulative incidence of neutrophil recovery at day-60 was 89% and day-100 acute graft-versus-host disease grade II-IV was 38%; use of methotrexate for graft-versus- host disease prophylaxis delayed engraftment (p=0.02), but decreased acute graft-versus-host disease (p=0.03). At 5-year, overall survival and event-free survival were 75% and 70%, respectively. Estimated 5 year- event-free survival was 83%, 73% and 55% for patients with clinical score 2, 4-5 and 3, respectively. In multivariate analysis, age<2years at umbilical cord blood transplantation and clinical phenotype X-linked thrombocytopenia were associated with improved event-free survival. Overall survival tended to be improved after 2007 (p=0.09). In conclusion, umbilical cord blood transplantation is a good alternative option for young children with Wiskott-Aldrich syndrome lacking an HLA identical stem cell donor
