RESUMO

STUDY QUESTION: Does LH protect mouse oocytes and female fertility from alkylating chemotherapy? SUMMARY ANSWER: LH treatment before and during chemotherapy prevents detrimental effects on follicles and reproductive lifespan. WHAT IS KNOWN ALREADY: Chemotherapies can damage the ovary, resulting in premature ovarian failure and reduced fertility in cancer survivors. LH was recently suggested to protect prepubertal mouse follicles from chemotoxic effects of cisplatin treatment. STUDY DESIGN, SIZE, DURATION: This experimental study investigated LH effects on primordial follicles exposed to chemotherapy. Seven-week-old CD-1 female mice were randomly allocated to four experimental groups: Control (n = 13), chemotherapy (ChT, n = 15), ChT+LH-1x (n = 15), and ChT+LH-5x (n = 8). To induce primary ovarian insufficiency (POI), animals in the ChT and ChT+LH groups were intraperitoneally injected with 120 mg/kg of cyclophosphamide and 12 mg/kg of busulfan, while control mice received vehicle. For LH treatment, the ChT+LH-1x and ChT+LH-5x animals received a 1 or 5 IU LH dose, respectively, before chemotherapy, then a second LH injection administered with chemotherapy 24 h later. Then, two animals/group were euthanized at 12 and 24 h to investigate the early ovarian response to LH, while remaining mice were housed for 30 days to evaluate short- and long-term reproductive outcomes. The effects of LH and chemotherapy on growing-stage follicles were analyzed in a parallel experiment. Seven-week-old NOD-SCID female mice were allocated to control (n = 5), ChT (n = 5), and ChT+LH-1x (n = 6) groups. Animals were treated as described above, but maintained for 7 days before reproductive assessment. PARTICIPANTS/MATERIALS, SETTING, METHODS: In the first experiment, follicular damage (phosphorylated H2AX histone (γH2AX) staining and terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) assay), apoptotic biomarkers (western blot), and DNA repair pathways (western blot and RT-qPCR) were assessed in ovaries collected at 12 and 24 h to determine early ovarian responses to LH. Thirty days after treatments, remaining mice were stimulated (10 IU of pregnant mare serum gonadotropin (PMSG) and 10 IU of hCG) and mated to collect ovaries, oocytes, and embryos. Histological analysis was performed on ovarian samples to investigate follicular populations and stromal status, and meiotic spindle and chromosome alignment was measured in oocytes by confocal microscopy. Long-term effects were monitored by assessing pregnancy rate and litter size during six consecutive breeding attempts. In the second experiment, mice were stimulated and mated 7 days after treatments and ovaries, oocytes, and embryos were collected. Follicular numbers, follicular protection (DNA damage and apoptosis by H2AX staining and TUNEL assay, respectively), and ovarian stroma were assessed. Oocyte quality was determined by confocal analysis. MAIN RESULTS AND THE ROLE OF CHANCE: LH treatment was sufficient to preserve ovarian reserve and follicular development, avoid atresia, and restore ovulation and meiotic spindle configuration in mature oocytes exposed at the primordial stage. LH improved the cumulative pregnancy rate and litter size in six consecutive breeding rounds, confirming the potential of LH treatment to preserve fertility. This protective effect appeared to be mediated by an enhanced early DNA repair response, via homologous recombination, and generation of anti-apoptotic signals in the ovary a few hours after injury with chemotherapy. This response ameliorated the chemotherapy-induced increase in DNA-damaged oocytes and apoptotic granulosa cells. LH treatment also protected growing follicles from chemotherapy. LH reversed the chemotherapy-induced depletion of primordial and primary follicular subpopulations, reduced oocyte DNA damage and granulosa cell apoptosis, restored mature oocyte cohort size, and improved meiotic spindle properties. LARGE SCALE DATA: N/A. LIMITATIONS, REASONS FOR CAUTION: This was a preliminary study performed with mouse ovarian samples. Therefore, preclinical research with human samples is required for validation. WIDER IMPLICATIONS OF THE FINDINGS: The current study tested if LH could protect the adult mouse ovarian reserve and reproductive lifespan from alkylating chemotherapy. These findings highlight the therapeutic potential of LH as a complementary non-surgical strategy for preserving fertility in female cancer patients. STUDY FUNDING/COMPETING INTEREST(S): This study was supported by grants from the Regional Valencian Ministry of Education (PROMETEO/2018/137), the Spanish Ministry of Science and Innovation (CP19/00141), and the Spanish Ministry of Education, Culture and Sports (FPU16/05264).

RESUMO

The rapid increasing of the population in combination with the emergence of new energy-consuming technologies has risen worldwide total energy consumption towards unprecedent values. Furthermore, fossil fuel reserves are running out very quickly and the polluting greenhouse gases emitted during their utilization need to be reduced. In this scenario, a few alternative energy sources have been proposed and, among these, proton exchange membrane (PEM) fuel cells are promising. Recently, polybenzimidazole-based polymers, featuring high chemical and thermal stability, in combination with fillers that can regulate the proton mobility, have attracted tremendous attention for their roles as PEMs in fuel cells. Recent advances in composite membranes based on polybenzimidazole (PBI) for high temperature PEM fuel cell applications are summarized and highlighted in this review. In addition, the challenges, future trends, and prospects of composite membranes based on PBI for solid electrolytes are also discussed.

RESUMO

We present an experimental study and a theoretical interpretation of the temperature dependence of the transport properties of doped CsH2PO4 salts in both protonic and superprotonic phases. Cesium phosphate based solid electrolytes are technologically relevant because their operational temperature range is about 100 to 300 °C in which a superprotonic transition may manifest depending on its mixed composition. The experimental study was carried out using impedance spectroscopy at the temperature range of 150-230 °C, and the protonic and superprotonic transport properties and proton concentrations were calculated and analyzed by using the electrode polarization, and the Debye and Cole-Cole models for the dielectric constant. We have shown that the transport properties predicted by the Cole-Cole model are consistent with the conductivity measurements whereas the Debye model shows some inconsistencies. We attribute this to the fact that the Cole-Cole model incorporates the effects of interactions among charge carriers better than the more commonly used Debye model. In this way, our work shows a more consistent approach to determine the transport properties of solid electrolytes and, therefore, provides a more reliable tool to analyze the transport properties of heterogeneous solid electrolytes that can be used in electrochemical devices, including fuel cells and supercapacitors.

RESUMO

This work is an analysis of the application of the generalized Monod kinetics model describing human corneal oxygen consumption during soft contact lens wear to models previously used by Chhabra et al. (J Biomed Mater Res B Appl Biomater, 2009a;90:202-209, Optom Vis Sci 2009b;86:454-466) and Larrea and Büchler (Invest Ophthalmol Vis Sci 2009;50:1076-1080). We use oxygen tension from in vivo estimations provided by Bonanno [Bonanno et al., Invest Ophthalmol Vis Sci 2002;43:371-376, and Bonanno et al 2009]. We consider four hydrogel and six silicone hydrogel lenses. The cornea is considered a single homogeneous layer, with constant oxygen permeability regardless of the type of lens worn. Our calculations yield different values for the maximum oxygen consumption rate Qc,max , whith differents oxygen tensions (high and low pc ) at the cornea-tears interface. Surprisingly, for both models, we observe an increase in oxygen consumption near an oxygen tension of 105 mmHg until a maximum is reached, then decreasing for higher levels of oxygen pressure. That is, when lowering the pressure of oxygen, the parameter Qc,max initially increases depending on the intensity of the change in pressure. Which, it could be related with the variation of the pH. Furthermore, it is also noted that to greater reductions in pressure, this parameter decreases, possibly due to changes in the concentration of glucose related to the anaerobic respiration. The averaged in vivo human corneal oxygen consumption rate of 1.47 × 10-4 cm3 of O2 /cm3 tissue s, with Monod kinetics model, considering all the lenses studied, is smaller than the average oxygen consumption rate value obtained using the Larrea and Büchler model. The impact that these calculations have on the oxygen partial pressure available at different depths in the corneal tissue is presented and discussed, taking into consideration previous models used in this study. © 2016 Wiley Periodicals, Inc.

RESUMO

El Comité Asesor de Vacunas de la Asociación Española de Pediatría (CAV-AEP) emite todos los años sus recomendaciones sobre la vacunación frente a este virus en la infancia y la adolescencia. La vacunación de la gripe es una actuación especialmente beneficiosa cuando va dirigida a personas (niños y adultos) que se incluyen en los grupos de población considerados de riesgo. Sin embargo, muchos niños y adolescentes pertenecientes a estos grupos de riesgo, y sus convivientes, continúan sin recibir, por distintas razones, dicha vacunación anual. Asimismo, se insiste en la recomendación de la vacunación de los profesionales sanitarios. En el presente documento se presentan las recomendaciones para la vacunación antigripal en la temporada 2016-2017, y se explican los fundamentos y limitaciones de las mismas. Es necesaria una mayor implicación de los profesionales, las autoridades sanitarias y todos los agentes sociales para transmitir cada año a la población, y de forma especial a los padres de niños y adolescentes pertenecientes a los grupos de riesgo, las recomendaciones de vacunación frente a la gripe estacional (AU)


The Advisory Committee on Immunization of the Spanish Association of Paediatrics issues its recommendations about vaccination against influenza virus in children and adolescents every year before the onset of the flu season. Influenza vaccination is particularly beneficial when aimed at individuals, both children and adults, who are included in the population groups considered at risk. However, for various reasons, many children and adolescents with underlying conditions and their contacts are still not given this vaccination annually. There is a need for a greater involvement of health professionals, health authorities and all social agents to inform the population, especially to the parents of children and adolescents in those risk groups, on the recommendations for seasonal influenza vaccination. In this document, current recommendations for influenza vaccination for the 2016-2017 season are presented, and reasons and limitations are explained. The recommendation for influenza vaccination is emphasized for health professionals (AU)

RESUMO

We study the microstructure of a granular amorphous silica ceramic material synthesized by spark plasma sintering. Using monodisperse spherical silica particles as precursor, spark plasma sintering yields a dense granular material with distinct granule boundaries. We use selective etching to obtain nanoscopic pores along the granule borders. We interrogate this highly interesting material structure by combining scanning electron microscopy, X-ray computed nanotomography and simulations based on random close packed spherical particles. We determine the degree of anisotropy caused by the uni-axial force applied during sintering, and our analysis shows that our synthesis method provides a means to avoid significant granule growth and to fabricate a material with well-controlled microstructure.

RESUMO

The Advisory Committee on Vaccines of the Spanish Association of Paediatrics (CAV-AEP) annually publishes the immunisation schedule which, in our opinion, estimates optimal for children resident in Spain, considering available evidence on current vaccines. We acknowledge the effort of the Ministry of Health during the last year in order to optimize the funded unified Spanish vaccination schedule, with the recent inclusion of pneumococcal and varicella vaccination in early infancy. Regarding the funded vaccines included in the official unified immunization schedule, taking into account available data, CAV-AEP recommends 2+1 strategy (2, 4 and 12 months) with hexavalent (DTPa-IPV-Hib-HB) vaccines and 13-valent pneumococcal conjugate vaccine. Administration of Tdap and poliomyelitis booster dose at the age of 6 is recommended, as well as Tdap vaccine for adolescents and pregnant women, between 27-36 weeks gestation. The two-dose scheme should be used for MMR (12 months and 2-4 years) and varicella (15 months and 2-4 years). Coverage of human papillomavirus vaccination in girls aged 11-12 with a two dose scheme (0, 6 months) should be improved. Information for male adolescents about potential beneficial effects of this immunisation should be provided as well. Regarding recommended unfunded immunisations, CAV-AEP recommends the administration of meningococcal B vaccine, due to the current availability in Spanish communitary pharmacies, with a 3+1 scheme (3, 5, 7 and 13-15 months). CAV-AEP requests the incorporation of this vaccine in the funded unified schedule. Vaccination against rotavirus is recommended in all infants. Annual influenza immunisation and vaccination against hepatitis A are indicated in population groups considered at risk.

RESUMO

The dielectric and mechanical spectroscopies of acetate of cis- and trans-2-phenyl-5-hydroxymethyl-1,3-dioxane are reported in the frequency domain from 10(-2) to 10(6)Hz. This ester has been selected in this study for its predominant α relaxation with regard to the ß relaxation, which can be neglected. This study consists of determining an interconversion algorithm between dielectric and mechanical measurements, given by using a relation between rotational and translational complex viscosities. These important viscosities were obtained from measures of the dielectric complex permittivity and by dynamic mechanical analysis, respectively. The definitions of rotational and translational viscosities were evaluated by means of fractional calculus, by using the fit parameters of the Havriliak-Negami empirical model obtained in the dielectric and mechanical characterization of the α relaxation. This interconversion algorithm is a generalization of the break of the Stokes-Einstein-Debye relationship. It uses a power law with an exponent defined as the shape factor, which modifies the translational viscosity. Two others factors are introduced for the interconversion, a shift factor, which displaces the translational viscosity in the frequency domain, and a scale factor, which makes equal values of the two viscosities. In this paper, the shape factor has been identified as the relation between the slopes of the moduli of the complex viscosities at higher frequency. This is interpreted as the degree of kinetic coupling between the molecular rotation and translational movements. Alternatively, another interconversion algorithm has been expressed by means of dielectric and mechanical moduli.

RESUMO

Las vacunaciones constituyen una de las principales herramientas de salud pública para el control de las enfermedades inmunoprevenibles. Si un niño es etiquetado de haber presentado una reacción alérgica a una vacuna es probable que se suspendan las siguientes inmunizaciones, con los riesgos que ello conlleva. La tasa de reacciones alérgicas graves es muy baja, oscilando entre 0,5 y 1/100.000 dosis. Las proteínas causantes de las reacciones alérgicas, más que los propios antígenos vacunales, son frecuentemente componentes residuales del proceso de fabricación, como son la gelatina y el huevo, y más raramente las levaduras o el látex. La mayoría de las reacciones son leves y localizadas en el lugar de la inyección, aunque en algunos casos pueden producirse reacciones anafilácticas graves. Si se sospecha que se ha producido una reacción alérgica inmediata a la vacuna, o si debemos vacunar a un niño con alergia a alguno de sus componentes, se deberá realizar un correcto diagnóstico de la posible alergia y conocer los componentes habituales de cada vacuna con el fin de determinar si la vacunación puede continuarse de forma segura


Vaccinations are one of the main public health tools for the control of vaccine-preventable diseases. If a child is labeled to have had an allergic reaction to a vaccine, the next immunizations will probably be suspended in that child, with the risks involved in this decision. The rate of severe allergic reactions is very low, ranging between 0.5-1/100,000 doses. The causes of allergic reactions to vaccines, more than the vaccine itself, are often due to residual protein components in the manufacturing process, such as gelatin or egg, and rarely to yeast or latex. Most of vaccine reactions are mild, localized at the site of injection, but in some circumstances, severe anaphylactic reactions can occur. If an immediate-type allergic reaction is suspected when vaccinating, or a child allergic to some of the vaccine components has to be vaccinated, a correct diagnosis of the possible allergy has to be made. The usual components of each vaccine should be known, in order to determine if vaccination can be performed safely on the child

RESUMO

La enfermedad meningocócica invasora, con sus 2 formas de presentación principales (sepsis y meningitis), es una patología grave y potencialmente mortal, causada por distintos serogrupos de Neisseria meningitidis, entre los cuales, actualmente, predomina el serogrupo B en Europa. La mayoría de los casos se producen en la edad pediátrica, con una mortalidad aproximada del 10% y un riesgo de secuelas permanentes del 20-30% entre los supervivientes. Presenta mayor incidencia y letalidad en niños sanos menores de 2-3 años, seguidos de los adolescentes, aunque puede ocurrir a cualquier edad. Hasta ahora no se contaba con ningún arma inmunopreventiva contra el meningococo B. Así, con la llegada a España de la única vacuna actualmente disponible, el Comité Asesor de Vacunas de la Asociación Española de Pediatría (CAV-AEP) ha analizado detalladamente tanto el potencial preventivo de dicha vacuna, como la situación peculiar administrativa de la misma en España. El objetivo de este documento es informar del posicionamiento del CAV-AEP en relación con la vacuna frente al meningococo B y el acceso a la misma por parte de la población infantil española, teniendo en cuenta que ha sido autorizada exclusivamente para el uso hospitalario en personas de riesgo. En Europa, la vacuna sí está disponible en farmacias, incluso incluida en calendarios oficiales de algunos países o regiones. Este comité considera que Bexsero(R) presenta un perfil de vacuna a incluir en todos los calendarios españoles y que debería estar disponible libremente en farmacias para su administración en todos los niños mayores de 2 meses


Meningococcal invasive disease, including the main clinical presentation forms (sepsis and meningitis), is a severe and potentially lethal infection caused by different serogroups of Neisseria meningitidis. Meningococcal serogroup B is the most prevalent in Europe. Most cases occur in children, with a mortality rate of 10% and a risk of permanent sequelae of 20-30% among survivors. The highest incidence and case fatality rates are observed in healthy children under 2-3 years old, followed by adolescents, although it can occur at any age. With the arrival in Spain of the only available vaccine against meningococcus B, the Advisory Committee on Vaccines of the Spanish Association of Paediatrics has analysed its preventive potential in detail, as well as its peculiar administrative situation in Spain. The purpose of this document is to publish the statement of the Committee as regards this vaccination and the access to it by the Spanish population, taking into account that it has been only authorized for people at risk. The vaccine is available free in the rest of Europe for those who want to acquire it, and in some countries and regions it has been introduced into the systematic immunisation schedules. The Committee considers that Bexsero(R) has a profile of a vaccine to be included in the official schedules of all the Spanish autonomous communities and insists on the need for it to be available in pharmacies for its administration in all children older than 2 months

RESUMO

The Advisory Committee on Vaccines of the Spanish Association of Paediatrics updates the immunisation schedule every year, taking into account epidemiological data as well as evidence on the safety, effectiveness and efficiency of current vaccines, including levels of recommendation. In our opinion, this is the optimal vaccination calendar for all children resident in Spain. Regarding the vaccines included in the official unified immunization schedule, the Committee emphasizes the administration of the first dose of hepatitis B either at birth or at 2 months of life; the recommendation of the first dose of MMR and varicella vaccine at the age of 12 months, with the second dose at the age of 2-3 years; DTaP or Tdap vaccine at the age of 6 years, followed by another Tdap booster dose at 11-12 years old; Tdap strategies for pregnant women and household contacts of the newborn, and immunization against human papillomavirus in girls aged 11-12 years old with a 2 dose scheme (0, 6 months). The Committee reasserts its recommendation to include vaccination against pneumococcal disease in the routine immunisation schedule, the same as it is being conducted in Western European countries. The recently authorised meningococcal B vaccine, currently blocked in Spain, exhibits the profile of a universal vaccine. The Committe insists on the need of having the vaccine available in communitary pharmacies. It has also proposed the free availability of varicella vaccines. Their efectiveness and safety have been confirmed when they are administred from the second year of life. Vaccination against rotavirus is recommended in all infants. The Committee stresses the need to vaccinate population groups considered at risk against influenza and hepatitis A.

RESUMO

El Comité Asesor de Vacunas de la Asociación Española de Pediatría actualiza anualmente su calendario de vacunaciones, tras un análisis tanto epidemiológico como de la seguridad, efectividad y eficiencia de las vacunas actuales, incluyendo grados de recomendación. Es el calendario que se estima idóneo actualmente para los niños residentes en España. En cuanto a las vacunas oficiales incluidas en el calendario común, se recalca la posibilidad de vacunar indistintamente frente a hepatitis B desde el nacimiento o desde los 2 meses; la recomendación de la primera dosis de triple vírica y de varicela a los 12 meses y la segunda a los 2-3 años; la administración de la vacuna DTPa o Tdpa a los 6 años, con refuerzo en la adolescencia; estrategias con Tdpa en embarazadas y convivientes del recién nacido, y la inmunización frente al papilomavirus en niñas a los 11-12 años con pauta de 2 dosis (0, 6 meses). Este comité insiste en la vacunación antineumocócica universal, tal y como se está llevando a cabo en todos los países de Europa Occidental. La vacuna frente al meningococo B, autorizada pero bloqueada actualmente en España, presenta un perfil de vacuna sistemática y se reivindica que, al menos, esté disponible en las farmacias comunitarias. Se propone, igualmente, la disponibilidad pública de las vacunas frente a la varicela, ya que han demostrado ser efectivas y seguras a partir del segundo año de vida. La vacunación frente al rotavirus es recomendable en todos los lactantes. La vacunación antigripal anual y la inmunización frente a la hepatitis A están indicadas en grupos de riesgo

We have graded, as routine vaccinations, those that the CAV-AEP consider all children should receive; as recommended those that fit the profile for universal childhood immunisation and would ideally be given to all children, but that can be prioritised according to the resources available for their public funding; and as risk group vaccinations those that specifically target individuals in special situations. Immunisation schedules tend to be dynamic and adaptable to ongoing epidemiological changes. Based on the latest epidemiological trends, CAV-AEP recommends the administration of the first dose of MMR and varicella vaccines at age 12 months, with the second dose at age 2-3 years; the administration of DTaP or Tdap vaccine at age 4-6 years, always followed by another Tdap dose at 11-12 years; and the three meningococcal C scheme at 2 months, 12 months and 12 years of age. It reasserts its recommendation to include vaccination against pneumococcal disease in the routine immunisation schedule. The CAV-AEP believes that the coverage of vaccination against human papillomavirus in girls aged 11-12 years must be increased. Universal vaccination against varicella in the second year of life is an effective strategy, and the immediate public availability of the vaccine is requested in order to guarantee the right of healthy children to be vaccinated. Vaccination against rotavirus is recommended in all infants due to the morbidity and elevated healthcare burden of the virus. The Committee stresses the need to vaccinate population groups considered at risk against influenza and hepatitis A. The recently authorised meningococcal B vaccine has opened a chapter of hope in the prevention of this disease. In anticipation of upcoming national and international studies, the Committee recommends the vaccine for the control of disease outbreaks, and insists on the need to be available in pharmacies. Finally, it emphasises the need to bring incomplete vaccinations up to date following the catch-up immunisation schedule.

RESUMO

El Comité Asesor de Vacunas de la Asociación Española de Pediatría (CAV-AEP) actualiza anualmente el calendario de vacunaciones teniendo en cuenta tanto aspectos epidemiológicos como de seguridad, efectividad y eficiencia de las vacunas. El presente calendario incluye grados de recomendación. Se consideran vacunas sistemáticas aquellas que el CAV-AEP estima que todos los niños deberían recibir; recomendadas, las que presentan un perfil de vacuna sistemática en la edad pediátrica y que es deseable que los niños reciban, pero que pueden ser priorizadas en función de los recursos para su financiación pública; y dirigidas a grupos de riesgo, aquellas con indicación preferente para personas en ciertas situaciones especiales. Los calendarios de vacunaciones tienen que ser dinámicos y adaptarse a los cambios epidemiológicos que vayan surgiendo. Teniendo en cuenta los últimos cambios en la epidemiología de las enfermedades, el CAV-AEP recomienda la administración de la 1.a dosis de las vacunas triple vírica y varicela a los 12 meses y la 2.a dosis a los 2-3 años; la administración de la vacuna DTPa o Tdpa a los 4-6 años, siempre acompañada de otra dosis de Tdpa a los 11-12 años; y el paso a un esquema 2 meses, 12 meses y 12 años de la vacunación frente al meningococo C. Se reafirma en la recomendación de incluir la vacunación frente al neumococo en el calendario de vacunación sistemático. El CAV-AEP estima que deben incrementarse las coberturas de vacunación frente al papiloma virus humano en las niñas a los 11-12 años. La vacunación universal frente a la varicela iniciada en el segundo año de vida es una estrategia efectiva, y se solicita la inmediata disponibilidad pública de la vacuna, reclamando el derecho a la prescripción y el derecho de los niños sanos a poder ser vacunados. La vacunación frente al rotavirus, dadas la morbilidad y la elevada carga sanitaria, es recomendable en todos los lactantes. Se insiste en la necesidad de vacunar frente a la gripe y a la hepatitis A a todos los que presenten factores de riesgo para dichas enfermedades. La vacuna frente al meningococo B, recientemente autorizada, abre un capítulo de esperanza en la prevención de esta enfermedad. En espera de próximos estudios nacionales e internacionales se recomienda, por el momento, para el control de brotes epidémicos y se insiste en el deseo de que sea comercializada libremente en las oficinas de farmacia. Por último, se insiste en la necesidad de actualizar las vacunaciones incompletas con las pautas de vacunación acelerada

RESUMO

The Advisory Committee on Vaccines of the Spanish Association of Paediatrics (CAV-AEP) updates the immunisation schedule every year, taking into account epidemiological data as well as evidence on the safety, effectiveness and efficiency of vaccines. The present schedule includes levels of recommendation. We have graded as routine vaccinations those that the CAV-AEP consider all children should receive; as recommended those that fit the profile for universal childhood immunisation and would ideally be given to all children, but that can be prioritised according to the resources available for their public funding; and as risk group vaccinations those that specifically target individuals in situations of risk. Immunisation schedules tend to be dynamic and adaptable to ongoing epidemiological changes. Nevertheless, the achievement of a unified immunisation schedule in all regions of Spain is a top priority for the CAV-AEP. Based on the latest epidemiological trends, CAV-AEP follows the innovations proposed in the last year's schedule, such as the administration of the first dose of the MMR and the varicella vaccines at age 12 months and the second dose at age 2-3 years, as well as the administration of the Tdap vaccine at age 4-6 years, always followed by another dose at 11-14 years of age, preferably at 11-12 years. The CAV-AEP believes that the coverage of vaccination against human papillomavirus in girls aged 11-14 years, preferably at 11-12 years, must increase. It reasserts its recommendation to include vaccination against pneumococcal disease in the routine immunisation schedule. Universal vaccination against varicella in the second year of life is an effective strategy and therefore a desirable objective. Vaccination against rotavirus is recommended in all infants due to the morbidity and elevated healthcare burden of the virus. The Committee stresses the need to vaccinate population groups considered at risk against influenza and hepatitis A. Finally, it emphasizes the need to bring incomplete vaccinations up to date following the catch-up immunisation schedule.

RESUMO

El Comité Asesor de Vacunas de la Asociación Española de Pediatría (CAV-AEP) actualiza anualmente el calendario de vacunaciones teniendo en cuenta tanto aspectos epidemiológicos, como de efectividad y eficiencia de las vacunas. El presente calendario incluye grados de recomendación. Se han considerado como vacunas sistemáticas aquellas que el CAV-AEP estima que todos los niños deberían recibir; como recomendadas las que presentan un perfil de vacuna sistemática en la edad pediátrica y que es deseable que los niños reciban, pero que pueden ser priorizadas en función de los recursos para su financiación pública; y dirigidas a grupos de riesgo aquellas con indicación preferente para personas en situaciones de riesgo. Los calendarios de vacunaciones tienen que ser dinámicos y adaptarse a los cambios epidemiológicos que vayan surgiendo, pero el CAV-AEP considera como objetivo prioritario la consecución de un calendario de vacunación único para toda España.Teniendo en cuenta los últimos cambios en la epidemiología de las enfermedades, las principales novedades propuestas en este calendario son la administración de la primera dosis de las vacunas triple vírica y varicela a los 12 meses (12-15 meses) y la segunda dosis a los 2-3 años, así como la administración de la vacuna Tdpa a los 4-6 años siempre acompañada de otra dosisa los 11-14 años. El CAV-AEP estima que deben incrementarse las coberturas de vacunación frente al papiloma virus humano en las niñas de 11 a 14 años. Se reafirma en la recomendación de incluir la vacunación frente al neumococo en el calendario de vacunación sistemática. La vacunación universal frente a la varicela en el segundo año de vida es una estrategia efectiva y por tanto un objetivo deseable.

The Advisory Committee on Vaccines of the Spanish Association of Pediatrics (CAVAEP) updates the immunization schedule every year, taking into account epidemiological data as well as evidence on the effectiveness and efficency of vaccines.The present schedule includes grades of recommendation. We have graded as routine vaccinations those that the CAV-AEP believes all children should receive; as recommended those that fit the profile for universal childhood immunization and would ideally be given to all children, but that can be prioritized according to the resources available for their public funding; and as risk group vaccinations those that specifically target individuals in situations of risk. Immunization schedules tend to be dynamic and adaptable to on going epidemiological changes. Nevertheless, the achievement of a unified immunization schedule in all regions of Spainis a top priority for the CAV-AEP. Based on the latest epidemiological trends, the main changes introduced to the schedule are the administration of the first dose of the MMR and the varicella vaccines at age 12 months(12---15 months) and the second dose at age 2---3 years, as well as the administration of the Tdap vaccine at age 4---6 years, always followed by another dose at 11---14 years of age.The CAV-AEP believes that the coverage of vaccination against human papilloma virus in girls aged 11---14 years must increase. It reasserts its recommendation to include vaccination against pneumococcal disease in the routine immunization schedule. Universal vaccination against varicellain the second year of life is an effective strategy and therefore a desirable objective. Vaccination against rotavirus is recommended in all infants due to the morbidity and elevated healthcare burden of the virus. The Committee stresses the need to vaccinate population groups considered at risk against influenza and hepatitis A. Finally, it emphasizes the need to bring incomplete vaccinations up to date following the catch-up immunization schedule (AU)
