Monitoring serologic response to single in ovo vaccination with an immune complex vaccine against infectious bursal disease in broilers.

The infectious bursal disease (IBD) virus is one of the most resistant and prevalent virus worldwide in the poultry industry, being vaccination the main tool to control the disease. For this reason, consistent and uniform immunization of broiler flocks against IBD is necessary to avoid the disease spreading. The aim of this study was to apply and assess an epidemiologic mapping tool focused on the immunization by in ovo single broiler vaccination using an immune complex IBD vaccine. With this regard, 7,576 serum samples were collected from 603 broiler flocks raised in 354 Spanish farms. To do so, blood samples were randomly collected from birds with ages between 35 to 51 d, and the serum was analyzed by ELISA. The results obtained from this study suggested a high uniform immunization against IBDV and a protective immunization between 35 and 51 d of age, with mean titer values ranging between 6,331 and 7,426. In addition, seroprevalence titer data of this large-scale monitoring study fitted a polynomial equation with a R2 value of 0.77, helping to explain and predict the humoral response to IBD vaccination. This seroprevalence map was applied to broiler production and was based on business intelligence tool that incorporates newly developed mapping tool to cover the need of having real-time information of humoral response to IBD vaccination and could be an effective tool for veterinary services to control and prevent IBD.

Construction and content validation of a measurement tool to evaluate person-centered therapeutic relationships in physiotherapy services.

OBJECTIVES: This study sought to develop a tool for evaluating person-centered therapeutic relationships within physiotherapy services, and to examine the content validity of the same. METHODS: A mixed qualitative and quantitative study was performed in three distinct phases: 1) the items were generated based on a literature review and a content analysis of focus groups of patients and physiotherapists; 2) an e-Delphi survey process was performed based on three rounds to select and refine the proposed questionnaire; 3) two rounds of cognitive interviews were conducted to evaluate the comprehension of items, the clarity of language and the appropriateness and relevance of content. RESULTS: Thirty-one items were generated based on the seven domains identified after the analysis of four focus groups of physiotherapists and four patient focus groups. Nine experts participated in the e-Delphi survey. Fifty-five patients participated in the two rounds of the cognitive pre-tests. Participating patients were from public and private physical therapy services. Based on the participants' suggestions, four items were removed, and four were added, whereas 16 were reworded. CONCLUSIONS: The final tool comprised 31 items divided into seven domains. The response format was based on a 5-point Likert frequency scale. The response options ranged from "strongly agree" to "strongly disagree".

Li-Fraumeni syndrome heterogeneity.

Clinical variability is commonly seen in Li-Fraumeni syndrome. Phenotypic heterogeneity is present among different families affected by the same pathogenic variant in TP53 gene and among members of the same family. However, causes of this huge clinical spectrum have not been studied in depth. TP53 type mutation, polymorphic variants in TP53 gene or in TP53-related genes, copy number variations in particular regions, and/or epigenetic deregulation of TP53 expression might be responsible for clinical heterogeneity. In this review, recent advances in the understanding of genetic and epigenetic aspects influencing Li-Fraumeni phenotype are discussed.

Retinoblastoma: hacia un diagnóstico más precoz / Retinoblastoma: towards an earlier diagnosis

OBJETIVOS: El número de enucleaciones y secuelas visuales por retinoblastoma es elevado. El objetivo del estudio fue evaluar diferentes aspectos diagnósticos y plantear estrategias que ayuden a mejorar el manejo clínico del retinoblastoma. Método: Estudio retrospectivo de 38 pacientes con retinoblastoma estudiados genéticamente (29 unilaterales, 9 bilaterales). Se evaluaron la edad de inicio, los signos clínicos y el tiempo de evolución, el número de enucleaciones, el momento de realización y la supervivencia a 5 años. Resultados: La leucocoria fue el signo clínico fundamental (presente en el 90% de los casos). El retraso diagnóstico medio fue de 3,2 meses. Entre los casos unilaterales se enuclearon el 76% de los ojos y en las formas bilaterales el 55%. Solo se encontró un fallecimiento entre los 25 pacientes seguidos durante al menos 5 años. Conclusiones: Las estrategias de diagnóstico y tratamiento del retinoblastoma necesitan ser actualizadas. Para ello, una buena coordinación entre pediatras y oftalmólogos es esencial. El manejo en centros de referencia, que dispongan de la tecnología y experiencia necesarias, debería contribuir a aumentar la tasa de preservación de órganos

OBJETIVOS: The number of enucleations and visual sequels due to retinoblastoma is high. The aim of this study was to evaluate the different diagnostic aspects and propose strategies that might improve the clinical management of this condition. Method: A retrospective study was conducted on 38 patients with retinoblastoma studied genetically (29 unilateral, 9 bilateral). The evaluation included: age of onset, clinical signs, and time since onset, number of enucleations, time to diagnosis, and survival at 5 years. Results: Leukocoria was the main clinical sign (present in 90% of cases). The mean diagnostic delay was 3.2 months. Among the unilateral cases, the eyes were enucleated in 76%, and 55% in the bilateral forms. Only one death was found among the 25 patients followed-up for at least 5 years. Conclusions: Retinoblastoma diagnostic and treatment strategies need to be updated. Good coordination between paediatricians and ophthalmologists is essential for this. Its management in reference centres, which have the necessary technology and experience, should contribute to increase the rate of organ preservation

Metastatic neuroblastoma in infants: are survival rates excellent only within the stringent framework of clinical trials?

Introduction. SIOPEN INES protocol yielded excellent 5-year survival rates for MYCN-non-amplified metastatic neuroblastoma. Patients deemed ineligible due to lack or delay of MYCN status or late registration were treated, but not included in the study. Our goal was to analyse survival at 10 years among the whole population. Materials and methods. Italian and Spanish metastatic INES patients’ data are reported. SPSS 20.0 was used for statistical analysis. Results. Among 98 infants, 27 had events and 19 died, while 79 were disease free. Five- and 10-year event-free survival (EFS) were 73 and 70 %, and overall survival (OS) was 81 and 74 %, respectively. MYCN status was significant for EFS, but not for OS in multivariate analysis. Conclusions. The survival rates of patients who complied with all the inclusion criteria for INES trials are higher compared to those that included also not registered patients. Five-year EFS and OS for INES 99.2 were 87.8 and 95.7 %, while our stage 4s population obtained 78 and 87 %. Concerning 99.3, 5-year EFS and OS were 86.7 and 95.6 %, while for stage 4 we registered 61 and 68 %. MYCN amplification had a strong impact on prognosis and therefore we consider it unacceptable that many patients were not studied for MYCN and probably inadequately treated. Ten-year survival rates were shown to decrease: EFS from 73 to 70 % and OS from 81 to 74 %, indicating a risk of late events, particularly in stage 4s. Population-based registries like European ENCCA WP 11-task 11 will possibly clarify these data (AU)

Contribution of endogenous bradykinin to fibrinolysis, inflammation, and blood product transfusion following cardiac surgery: a randomized clinical trial.

Bradykinin increases during cardiopulmonary bypass (CPB) and stimulates the release of nitric oxide, inflammatory cytokines, and tissue-type plasminogen activator (t-PA), acting through its B2 receptor. This study tested the hypothesis that endogenous bradykinin contributes to the fibrinolytic and inflammatory response to CPB and that bradykinin B2 receptor antagonism reduces fibrinolysis, inflammation, and subsequent transfusion requirements. Patients (N = 115) were prospectively randomized to placebo, ε-aminocaproic acid (EACA), or HOE 140, a bradykinin B2 receptor antagonist. Bradykinin B2 receptor antagonism decreased intraoperative fibrinolytic capacity as much as EACA, but only EACA decreased D-dimer formation and tended to decrease postoperative bleeding. Although EACA and HOE 140 decreased fibrinolysis and EACA attenuated blood loss, these treatments did not reduce the proportion of patients transfused. These data suggest that endogenous bradykinin contributes to t-PA generation in patients undergoing CPB, but that additional effects on plasmin generation contribute to decreased D-dimer concentrations during EACA treatment.

Comparative effects of angiotensin receptor blockade and ACE inhibition on the fibrinolytic and inflammatory responses to cardiopulmonary bypass.

The effects of angiotensin-converting enzyme (ACE) inhibition and angiotensin II type 1 receptor blockade (ARB) on fibrinolysis and inflammation after cardiopulmonary bypass (CPB) are uncertain. This study tested the hypothesis that ACE inhibition enhances fibrinolysis and inflammation to a greater extent than ARB in patients undergoing CPB. One week to 5 days before surgery, patients were randomized to ramipril 5 mg/day, candesartan 16 mg/day, or placebo. ACE inhibition increased intraoperative bradykinin and tissue-type plasminogen activator (t-PA ) concentrations as compared to AR B. Both ACE inhibition and AR B decreased the need for plasma transfusion relative to placebo, but only ACE inhibition decreased the duration of hospital stay. Neither ACE inhibition nor AR B significantly affected concentrations of plasminogen activator inhibitor-1 (PAI -1), interleukin (IL )-6, IL -8, or IL -10. ACE inhibition enhanced intraoperative fibrinolysis without increasing the likelihood of red-cell transfusion. By contrast, neither ACE inhibition nor ARB affected the inflammatory response. ACE inhibitors and ARBs may be safely continued until the day of surgery.

[Parental presence in the operating room: effect on the quality of anesthetic induction and postoperative agitation in children]. / Efectos de la presencia paterna en quirófano sobre la calidad de la inducción anestésica y agitación postoperatoria en niños.

BACKGROUND AND OBJECTIVE: Various nonpharmacologic strategies for reducing anxiety in children and improving cooperation during induction of anesthesia have been investigated. Parental presence during anesthetic induction has been the alternative studied most often, especially in English-speaking populations. Mixed results have been reported, however. The aim of this study was to evaluate the quality of anesthetic induction and the development of postoperative agitation in Spanish children undergoing ear, nose, or throat surgery with or without parental presence in the operating room. PATIENTS AND METHODS: Children in American Society of Anesthesiologists class 1 or 2 who were scheduled for ear, nose or throat surgery under inhalation anesthesia were randomized to 2 groups for presence or absence of a parent in the operating room. The induction experience was classified as easy, carried out with moderate resistance, or traumatic. The postoperative period was assessed as easy or traumatic. RESULTS: Forty children were randomized. Time to onset of anesthesia was similar in the 2 groups. Induction was easy for 65% of the children with parental presence and for 25% of the children without a parent present (P < .05). Induction was traumatic for 25% in the parental presence group and for 35% in the parental absence group (P < .05). The incidence of moderate resistance during induction was similar in the 2 groups; the quality of the postoperative experience was also similar. CONCLUSIONS: Parental presence during induction of inhalation anesthesia improves the induction experience of nonpremeditated Spanish children, increasing the incidence of easy induction and decreasing the presence of traumatic induction. The quality of the postoperative experience is similar.

Efectos de la presencia paterna en quirófano sobre la calidad de la inducción anestésica y agitación postoperatoria en niños / Parental presence in the operating room: effect on the quality of anesthetic induction and postoperative agitation in children

Objetivos: Se han investigado diversas alternativas no farmacológicas para reducir el estrés y mejorar la cooperación de los niños durante la inducción anestésica. La presencia de los padres durante la inducción anestésica ha sido la intervención más comúnmente estudiada, sobre todo en la población anglosajona y con resultados contradictorios. El objetivo del presente trabajo es evaluar la calidad de la inducción anestésica y del postoperatorio según la presencia paterna o no durante la misma en niños españoles no premedicados sometidos a cirugía otorrinolaringológica. Pacientes y métodos: Niños ASA I-II programados para cirugía otorrinolaringológica con inducción inhalatoria, asignados de forma aleatoria a dos grupos, según entraran los padres (grupo P) o no (grupo C) en el quirófano. La calidad de la inducción anestésica fue valorada como suave, moderada o traumática y el postoperatorio como suave o traumático. Resultados: Se incluyeron 40 niños. El tiempo de inducción anestésica fue similar en ambos grupos. Hubo una inducción suave en el 65% de los niños del grupo P frente al 25% en el grupo C (p<0,05), y una inducción traumática en el 25% de los niños del grupo P, frente al 35% del grupo C (p<0,05). La incidencia de inducción moderada y la calidad de postoperatorio fueron similares en ambos grupos. Conclusión: La presencia paterna durante la inducción de la anestesia inhalatoria mejora la calidad de la inducción del niño no premedicado, aumentando la incidencia de inducciones suaves frente a las traumáticas. No se han encontrado diferencias en la calidad del postoperatorio(AU)

Artritis séptica neumocócica de rodilla como causa de enfermedad tromboembólica venosa / Venous Thromboembolic Disease due to septic pneumococcal arthritis of the knee

La artritis séptica neumocócica es una entidad poco frecuente en adultos. Se produce por una disemincación hematógena desde algún foco infeccioso. La afectación poliarticular es menos frecuente si bien es más frecuente que en otros patógenos causantes de artritis. Presentamos el caso de una paciente con artritis séptica neumocócica en la rodilla derecha secundaria a una neumonía, la compresión de la cual causó una trombosis venosa profunda (TVP) en la extremidad ipsilateral y un tromboembolismo pulmonar (AU)

Streptococcus pneumoniae induced septic arthritis is very rare in adults. It is produced by hematogenous spread from other infectious areas. Polyarthritis involvement is less frequent, although it is more frequent than in other arthritis causing pathogens. We report a clinical case of a woman with septic pneumococcal arthritis of the knee secondary to pneumonia, the compression of which caused deep venous thrombosis (DVT) in the ipsilateral limb and pulmonary thromboembolism (AU)

HIV/STI co-infection among men who have sex with men in Spain.

In Spain, neither the HIV nor the STI national surveillance systems collect information on HIV/STI co-infection. However, there are two networks based on HIV/STI clinics which gather this data. We describe HIV prevalence in men who have sex with men (MSM) diagnosed with infectious syphilis and/or gonorrhoea in 15 STI clinics; and concurrent diagnoses of STI in MSM newly diagnosed with HIV in 19 HIV/STI clinics. In total, 572 MSM were diagnosed with infectious syphilis and 580 with gonorrhoea during 2005-2007. HIV prevalence among syphilis and gonorrhoea cases was 29.8% and 15.2% respectively. In the multivariate analysis, HIV/syphilis co-infection was associated with being Latin American; having a history of STI; reporting exclusively anal intercourse; and having sex with casual or several types of partners. HIV and gonorrhoea co-infection was associated with age older than 45 years; having no education or only primary education completed; and having a history of STI. In total, 1,462 HIV infections were newly diagnosed among MSM during 2003-2007. Of these, 31.0% were diagnosed with other STI at the same time. Factors associated with STI co-infection among new HIV cases in MSM were being Latin American; and having sex with casual partners or with both steady and casual partners. In Spain, a considerable proportion of MSM are co-infected with HIV and STI.

Subtelomeric analysis of pediatric astrocytoma: subchromosomal instability is a distinctive feature of pleomorphic xanthoastrocytoma.

Astrocytic neoplasms are genetically heterogeneous; however a low frequency of genomic changes has been found in juvenile pilocytic astrocytoma (PA) in molecular studies. Concerning pleomorphic xanthoastrocytomas (PXA), recent studies have given heterogeneous results for chromosomal alterations. We studied the subtelomeric regions of 19 primary astrocytoma tumors. Results were near normality for the PA group with relative scarcity of chromosomal imbalances, except for the duplication of 3pter in 4/15 and deletion of 21qter in 5/15 of them. In contrast, a specific profile was observed in the 4 PXA tumoral samples. This involved 3pter, 14qter and 19pter duplication and 4qter, 6qter, 9qter, 13cen, 17pter, 18qter and 21qter deletion. Our results indicate that the chromosomal and genetic aberrations in PXAs differed from those typically associated with the diffusely infiltrating astrocytic and oligodendroglial gliomas. These genetic differences would likely contribute to the more favorable behavior of PXAs and may be helpful for molecular differential diagnosis of pediatric cerebral tumors.

Clinical trial: a randomized controlled study on prevention of variceal rebleeding comparing nadolol + ligation vs. hepatic venous pressure gradient-guided pharmacological therapy.

BACKGROUND: Hepatic venous pressure gradient (HVPG) monitoring of therapy to prevent variceal rebleeding provides strong prognostic information. Treatment of nonresponders to beta-blockers +/- nitrates has not been clarified. AIM: To assess the value of HVPG-guided therapy using nadolol + prazosin in nonresponders to nadolol + isosorbide-5-mononitrate (ISMN) compared with a control group treated with nadolol + ligation. METHODS: Cirrhotic patients with variceal bleeding were randomized to HVPG-guided therapy (n = 30) or nadolol + ligation (n = 29). A Baseline haemodynamic study was performed and repeated within 1 month. In the guided-therapy group, nonresponders to nadolol + ISMN received nadolol and carefully titrated prazosin and had a third haemodynamic study. RESULTS: Nadolol + prazosin decreased HVPG in nonresponders to nadolol + ISMN (P < 0.001). Finally, 74% of patients were responders in the guided-therapy group vs. 32% in the nadolol + ligation group (P < 0.01). The probability of rebleeding was lower in responders than in nonresponders in the guided therapy group (P < 0.01), but not in the nadolol + ligation group (P = 0.41). In all, 57% of nonresponders rebled in the guided-therapy group and 20% in the nadolol + ligation group (P = 0.05). The incidence of complications was similar. CONCLUSIONS: In patients treated to prevent variceal rebleeding, the association of nadolol and prazosin effectively rescued nonresponders to nadolol and ISMN, improving the haemodynamic response observed in controls receiving nadolol and endoscopic variceal ligation. Our results also suggest that ligation may rescue nonresponders.
