Assessment of the Association of Health with the Liberalisation of Trade in Services under the World Trade Organisation

Background: The liberalisation of trade in services which began in 1995 under the General Agreement on Trade in Services (GATS) of the World Trade Organisation (WTO) has generated arguments for and against its potential health effects. Our goal was to explore the relationship between the liberalisation of services under the GATS and three health indicators – life expectancy (LE), under-5 mortality (U5M) and maternal mortality (MM) - since the WTO was established. Methods and Findings: This was a cross-sectional ecological study that explored the association in 2010 and 1995 between liberalisation and health (LE, U5M and MM), and between liberalisation and progress in health in the period 1995–2010, considering variables related to economic and social policies such as per capita income (GDP pc), public expenditure on health (PEH), and income inequality (Gini index). The units of observation and analysis were WTO member countries with data available for 2010 (n = 116), 1995 (n = 114) and 1995–2010 (n = 114). We conducted bivariate and multivariate linear regression analyses adjusted for GDP pc, Gini and PEH. Increased global liberalisation in services under the WTO was associated with better health in 2010 (U5M: 20.358 p,0.001; MM: 20.338 p = 0.001; LE: 0.247 p = 0.008) and in 1995, after adjusting for economic and social policy variables. For the period 1995–2010, progress in health was associated with income equality, PEH and per capita income. No association was found with global liberalisation in services. Conclusions: The favourable association in 2010 between health and liberalisation in services under the WTO seems to reflect a pre-WTO association observed in the 1995 data. However, this liberalisation did not appear as a factor associated with progress in health during 1995–2010. Income equality, health expenditure and per capita income were more powerful determinants of the health of populations.This study was funded by the Carlos III Health Institute and the Programme for Promotion of Biomedical and Health Sciences (http://www.isciii.es/) of the Spanish Ministry of Health and Consumer Affairs (Ref.

Recommendations for the Clinical Approach to Immune Thrombocytopenia: Spanish ITP Working Group (GEPTI)

Glucocorticoids; Intravenous immunoglobulins; Primary immune thrombocytopeniaGlucocorticoides; Immunoglobulines intravenoses; Trombocitopènia immune primàriaGlucocorticoides; Inmunoglobulinas intravenosas; Trombocitopenia inmune primariaPrimary immune thrombocytopenia (ITP) is a complex autoimmune disease whose hallmark is a deregulation of cellular and humoral immunity leading to increased destruction and reduced production of platelets. The heterogeneity of presentation and clinical course hampers personalized approaches for diagnosis and management. In 2021, the Spanish ITP Group (GEPTI) of the Spanish Society of Hematology and Hemotherapy (SEHH) updated a consensus document that had been launched in 2011. The updated guidelines have been the reference for the diagnosis and management of primary ITP in Spain ever since. Nevertheless, the emergence of new tools and strategies makes it advisable to review them again. For this reason, we have updated the main recommendations appropriately. Our aim is to provide a practical tool to facilitate the integral management of all aspects of primary ITP management

Simoctocog alfa (Nuwiq ® ) in children: early steps in life’s journey for people with severe hemophilia A

People with severe hemophilia A usually experience their first bleed early in life. In children with severe hemophilia A, primary prophylaxis is recommended to prevent recurrent and potentially life-threatening bleeds that significantly impact day-to-day life. Factor VIII (FVIII) prophylaxis is well-established in children and has been shown to reduce the development of hemophilic arthropathy. However, a major challenge of FVIII therapy is the development of neutralizing anti-FVIII antibodies (FVIII inhibitors). Simoctocog alfa (Nuwiq®) is a human cell line-derived recombinant FVIII (rFVIII) whose immunogenicity, efficacy, and safety have been studied in 167 children with severe hemophilia A across two prospective clinical trials and their long-term extensions. In 105 previously untreated children, the inhibitor rate of 16.2% for high-titer inhibitors (26.7% for all inhibitors) was lower than published rates for hamster cell line-derived rFVIII products. There was no inhibitor development in previously untreated children with non-null F8 mutations and in previously treated children. In a case series of 10 inhibitor patients, 8 (80%) underwent successful immune tolerance induction with simoctocog alfa with a median time to undetectable inhibitor of 3.5 months. In an analysis of 96 children who enrolled in the extension studies and received long-term simoctocog alfa prophylaxis for up to 5 years, median spontaneous, joint, and total annualized bleeding rates were 0.3, 0.4, and 1.8, respectively. No thromboembolisms were reported in any of the 167 children, and there were no treatment-related deaths. Optimal care of children should consider several factors, including minimization of inhibitor development risk, maintaining tolerance to FVIII, highly effective bleed prevention and treatment, safety, and impact on long-term outcomes such as bone and joint health. In this context we review the pediatric clinical data and ongoing studies with simoctocog alfa

Clinical Efficacy and Safety of Fanhdi®, a Plasma-Derived VWF/Factor VIII Concentrate, in von Willebrand Disease in Spain: A Retrospective Study

Prophylaxis; Von willebrand diseaseProfilaxis; Enfermedad de von willebrandProfilaxi; Malaltia de von willebrandObjective To evaluate the efficacy and safety of a plasma-derived factor VIII concentrate containing von Willebrand Factor (pdVWF/FVIII) in standard clinical practice in von Willebrand Disease (VWD) patients. Methods A retrospective, multicentric, observational study of VWD patients treated with Fanhdi®, a pdVWF/FVIII concentrate, from January 2011 to December 2017 was conducted at 14 centers in Spain. Efficacy and safety were evaluated for acute bleeding episodes, for prevention of bleeding in surgeries, and for secondary long-term prophylaxis. Results Seventy-two eligible patients, type 1, 2, 3 VWD (25%/38.9%/36.1%) were treated for spontaneous and traumatic bleeding (140 episodes, n = 41 patients), to prevent surgical bleeding (69 episodes, n = 43 patients); and for secondary long-term prophylaxis (18 programs, n = 13 patients). Replacement therapy with pdVWF/FVIII showed an excellent to good clinical efficacy in 96.7% of the bleeding episodes, 100% during surgical procedures and 100% during prophylaxis. No adverse events (AEs), nor serious AEs related to the product were observed. Conclusions Fanhdi® was effective, safe and well tolerated in the management of bleeding episodes, the prevention of bleeding during surgeries, and for secondary long-term prophylaxis in VWD patients.This work was supported by Grifols, manufacturer of the pdVWF/FVIII, Fanhdi®

Haemophilia: Reasons for visits to the paediatric emergency department

Introducción: La hemofilia es una enfermedad rara, por lo que su abordaje en Urgencias puede suponer un reto para los pediatras. Objetivos: Describir la frecuencia y motivos de consulta de los niños hemofílicos en Urgencias. Material y métodos: Estudio retrospectivo longitudinal realizado en Urgencias Pediátricas de un hospital de tercer nivel. Se incluyeron hemofílicos A y B, desde el nacimiento hasta los 16 años, que consultaron por cualquier motivo durante 6 años (2011-2016). Se analizaron: edad, tipo y gravedad de hemofilia, motivo de consulta, profilaxis domiciliaria frente a sangrados, pruebas complementarias, diagnóstico establecido, tratamiento y número de visitas a Urgencias. Resultados: Se analizaron 116 varones con un total de 604 visitas. La media de edad fue de 5,5 años y la mediana de 5,3. De ellos, 101 pacientes eran hemofílicos A (38 leves, 4 moderados, 59 graves) y 15 hemofílicos B (9 leves, 3 moderados, 3 graves). Los principales motivos de consulta (clasificados en triaje) fueron: problema musculoesquelético/traumático o sangrado (66,7%), causas no relacionadas con hemofilia (29%), sospecha de infección de catéter central (2,8%) y administración rutinaria de factor (1,5%). Se realizaron pruebas complementarias en 335 visitas (55,5%). Del total, 317 consultas (52,5%) requirieron factor; 103 episodios (17,1%) precisaron ingreso, cuyos principales motivos fueron: traumatismo craneoencefálico (35,9%), infección de catéter venoso central (13,6%), hemartrosis (8,7%), hematoma muscular (6,8%) y hematuria (5,8%). Conclusión: Los pacientes consultaron por causas habituales de la edad pediátrica, pero también lo hicieron por motivos específicos de su enfermedad; lo más frecuente fue el problema musculoesquelético/traumático o sangrado. El Servicio de Urgencias es un componente indispensable en su atenciónIntroduction: Haemophilia is a rare disease and its management can pose a challenge to Emergency Department paediatricians. Aim: To describe the frequency and reasons for consultation by haemophilic children in the ED. Materials and methods: Longitudinal retrospective study was conducted in a paediatric Emergency Department of a tertiary care hospital. The study included haemophiliacs A and B, ages 0 to 16 years old, and who had consulted the Emergency Department for whatever reason over a span of 6 years (2011-2016). The data analysed include: age, type and severity of haemophilia, reason for query, prophylactic status, complementary examinations, established diagnosis, treatment, and number of visits to the Emergency Department. Results: The analysis included 116 males with a total of 604 Emergency Department visits. The mean age was 5.5 years, and the median age was 5.3 years. A total of 101 patients were categorised as haemophiliac A (38 mild, 4 moderate, 59 severe), and 15 as haemophiliac B (9 mild, 3 moderate, 3 severe). The main reasons for initial Emergency Department visits (ranked by triage) were: musculoskeletal problems/injury or bleeding (66.7%), causes unrelated to haemophilia (29%), suspected central venous catheter related infection (2.8%), and routine clotting factor infusion (1.5%). Additional tests were conducted during 335 visits (55.5%). Factor replacement was undertaken in 317 visits (52.5%). A total of 103 episodes (17.1%) required hospital admission, due to: head trauma (35.9%), central venous catheter -related infection (13.6%), haemarthrosis (8.7%), muscle haematoma (6.8%), and haematuria (5.8%). Conclusion: Haemophilic patients went to the Emergency Department for common paediatric causes, but also requested consultation on specific problems related to haemophilia, with musculoskeletal problems/injury or bleeding being the main issues. The paediatric Emergency Department is an indispensable component of haemophilia car

Educar para la Participación Ciudadana. Un Reto para la Escuela del Siglo XXI

Nuestro mundo tiene graves problemas que deben ser afrontados con la participación de los ciudadanos. Ello exige la construcción de una ciudadanía verdaderamente participativa. La sociedad espera de la escuela que contribuya a educar para este tipo de ciudadanía, pero la escuela actual no puede responder adecuadamente a este requerimiento ni es la única institución responsable de este objetivo.
