Evaluation of a Cooperia oncophora double-domain ASP-based vaccine against Cooperia spp. infections in cattle and sheep.

A double-domain activation-associated secreted protein (dd-Co-ASP) isolated from the bovine small intestinal parasite Cooperia oncophora was previously shown to be an effective vaccine candidate to protect calves against a homologous challenge infection. The aim of this study was to investigate whether the dd-Co-ASP protein, purified from a Belgian C. oncophora isolate, would offer protection against a C. oncophora isolate from the southern hemisphere as well as other Cooperia species such as C. punctata in cattle and C. curticei in sheep. Two vaccination studies were performed, i.e. one in cattle and one in sheep, in which the protective effects of dd-Co-ASP, supplemented with Quil A as an adjuvant, were compared with an adjuvant control. Whereas our results showed a 75 % reduction in Cooperia spp. cumulative faecal egg counts, the results obtained in sheep demonstrated that dd-Co-ASP was ineffective in raising a protective immune response against a C. curticei challenge infection. Even though sequence analysis of the dd-Co-ASP gene revealed restricted sequence heterogeneity in the double domain ASP within and between bovine Cooperia species, the results of the vaccine study suggest that there is sufficient conservation at the protein level to yield cross-protection, holding promise for the development of a general Cooperia vaccine for use in cattle.

Introducción: Reducir la pobreza, reducir la mortalidad de menores de 5 años (< 5 años) y lograr cobertura universal de salud son parte de los Objetivos de Desarrollo Sostenible (ODS). Objetivo: determinar el gasto de bolsillo de salud (GBS) ante la enfermedad de < 5 años y su inci-dencia económica en los hogares según su condición de pobreza en Paraguay. Material y Método: se analizó la Encuesta Permanente de Hogares del 2014, considerando la defi-nición oficial de pobreza y la referencia de enfermedad o accidente en un trimestre. Se calculó el promedio de GBS por hogar, la incidencia sobre el ingreso monetario trimestral (IM), sobre los sub-sidios estatales por pobreza (IS) y el equivalente de subsistencia o alimentación (EA). Resultados: Entre los hogares no pobres: 41,1% (IC 37,3 a 45,0) tuvo al menos 1 enfermo < 5 años, de los cuales 76,6% (IC 71,5 a 81,0) tuvo GBS, siendo en promedio 223.455 Gs. (DE 37.445). Los medicamentos fueron 68,9% (IC 61,7 a 76,1) del total. La IM fue 1,7% (IC 1,1 a 2,3). Entre los ho-gares pobres: 50,0% (IC 44,7 a 52,2) tuvo al menos 1 enfermo < 5 años, de los cuales 71,2% (IC 64,7 a 76,9) tuvo GBS, siendo en promedio 125.545 Gs. (DE 14.749). Los medicamentos fueron 77,5% (IC 69,2 a 85,7) del total. La IM fue 4,0% (IC 2,3 a 5,8). La IS fue 54,6% (IC 13,0 a 96,2) y el EA fue el equivalente a 7 días de alimentación en promedio (DE 1,5). Conclusión: Ante los retos de los ODS, Paraguay requiere de mayor protección financiera en salud para niñas y niños < 5 años, mediante sinergias de las políticas de reducción de pobreza y de salud. Palabras Clave: gasto de bolsillo de salud, cobertura universal de salud, derecho a la salud, pobreza, menores de 5 años.

Introduction: Reducing poverty, reducing the mortality of children under 5 years (<5 years) and achieving universal health coverage are part of the Sustainable Development Goals (SDGs). Objective: to determine the out-of-pocket health expenditure (GBS) for the disease of <5 years and its economic impact on households according to their poverty status in Para-guay. Material and Method: the 2014 Permanent Household Survey was analyzed, considering the official definition of poverty and the reference of illness or accident in a quarter. The average of GBS per household, the incidence on quarterly monetary income (IM), on state subsidies for poverty (IS) and the equivalent of feeding (EA) were calculated. Results: Among non-poor households: 41.1% (CI 37.3 to 45.0) had at least 1 <5 years ill or injured, of which 76.6% (CI 71.5 to 81.0) had GBS , being on average 223,455 Gs. (DE 37,445). The medications were 68.9% (CI 61.7 to 76.1) of the total. The IM was 1.7% (CI 1.1 to 2.3). Among poor households: 50.0% (CI 44.7 to 52.2) had at least 1 <5 years ill or injured, of which 71.2% (CI 64.7 to 76.9) had GBS, being in average 125,545 Gs. (DE 14,749). The medications were 77.5% (CI 69.2 to 85.7) of the total. The IM was 4.0% (CI 2.3 to 5.8). The IS was 54,6% (IC 13,0 a 96,2) and the EA was the equivalent of 7 days of feeding on av-erage (SD 1.5). Conclusion: Given the challenges of the SDGs, Paraguay requires greater financial protection in health for children under 5 years, through synergies of poverty reduction and health policies. Keywords: out-of-pocket health expenditure, universal health coverage, right to health, pov-erty, children under 5 years.

Introduction: Reducing poverty and achieving universal health coverage for people of all ages are part of the Sustainable Development Goal. Objective: determine the Out-of-pocket Health Expenditure (GBS) for people 60 and older (≥ 60 years) who are sick and its economic impact on households according to their poverty status in Paraguay. Material and Method: the 2014 Permanent Household Survey was analyzed, considering the official definition of poverty and the reference of illness or accident in a quarter. The average of GBS per household, the impact on quarterly monetary risk (IM) and on state subsidies for food pensions for the elderly (IPa). Results: Of 1,621,525 homes in the country 435,448 had at least 1 person 60 years, of which 188,715 had at least 1 of them ill or injured and 144,554 reported GBS. Among the non-poor households: 11.6% (IC 10.5 to 12.9) had at least 1 ill person ≥ 60 years, of which 75.8% (IC 71.2 to 79.8) had GBS, being on average 547,931 Gs. (DE 58,251). The medications were 53.3% (IC 45.2 to 61.5) from total. There was an IM of 5,7% (IC 4.6 to 6.9). Among the poor households: 11.6% (IC 9.6 to 14.0) had at least 1 ill person ≥ 60 years, of which 79.5% (IC 70.7 to 86,2) had GBS, being on average 341,542 Gs. (DE 40,101). The medications were 71.3 % (IC 61.9 to 80.7) from total. There was an IM of 11.5% (IC 7.0 to 16.0). There was an IPa of 16.9% (IC 4.4 to 29.4). The GBS was the equivalent to 19 days of feeding on average (DE 3.71). Conclusion: Paraguay requires more financial protection for older adults through synergies of poverty reduction and health policies.

Prognostic role for the derived neutrophil-to-lymphocyte ratio in early breast cancer: a GEICAM/9906 substudy.

PURPOSE: Elevated markers of host inflammation, a hallmark of cancer, have been associated with worse outcomes in several solid tumors. Here, we explore the prognostic role of the derived neutrophil-to-lymphocyte ratio (dNLR), across different tumor subtypes, in patients with early breast cancer. PATIENTS AND METHODS: This was a retrospective analysis of 1246 patients with lymph node-positive, operable early breast cancer enrolled in the GEICAM/9906 trial, a multicenter randomized phase 3 study evaluating adjuvant chemotherapy. dNLR was calculated as the ratio of neutrophils and the difference between total leukocytes and neutrophils in peripheral blood before chemotherapy. Disease-free survival (DFS) and overall survival were explored using a Cox proportional hazard analysis. RESULTS: The analysis comprised 1243 (99.8%) patients with dNLR data, with a median follow-up of 10 years. Data on intrinsic subtypes were available from 818 (66%) patients (luminal A 34%, luminal B 32%, HER2-enriched 21% and basal-like 9%). Median dNLR was 1.35 [interquartile range (IQR) 1.08-1.71]. In the whole population, dNLR was not prognostic after adjustment for clinico-pathological factors. However, dNLR ≥ 1.35 was independently associated with worse DFS in the hormone receptor-negative/HER2+ population (HR 2.86; p = 0.038) and in patients with one to three lymph node metastases (HR 1.32, p = 0.032). There was a non-significant association with worse DFS in non-luminal and in HER2-enriched tumors (HR 1.40, p = 0.085 and HR 1.53, p = 0.067). No significant interaction was observed between the treatment arm and dNLR. CONCLUSION: Elevated dNLR appears to be an adverse prognostic factor in hormone receptor-negative early breast cancer.

Validez diagnóstica de la escala de alvarado en pacientes con dolor abdominal sugestivo de apendicitis, en un hospital de tercer nivel, del sur de bogotá

El dolor abdominal agudo es uno de los síntomas por los que un paciente asiste al servicio de urgencias de cualquier hospital, a nivel mundial, representando entre un 5 y 10% del total de consultas, constituyéndose para el médico de urgencias y especialistas interconsultados, un reto, dado que encierra varias patologías, que pueden ser o no quirúrgicas y que de no ser diagnosticadas, correcta y oportunamente, se pueden convertir en fatales, como la apendicitis, la condición patológica y quirúrgica, la que, frecuentemente, se ve enfrentado el cirujano general. El paciente, se puede presentar con signos y síntomas muy variados, que van desde un cuadro claro de apendicitis o no tener signos ni síntomas que sugieran, como diagnóstico, esta patología, por lo cual, se han desarrollado escalas que faciliten o aporten ayuda al médico para un correcto diagnóstico y posterior tratamiento. La escala de Alvarado hace parte de estas ayudas diagnósticas, siendo un método económico, no invasivo, rápido y confiable. Se evaluó por medio de este proyecto, la validez de la escala en la USS Tunal de IIII nivel, al ser uno de los hospitales más grandes y concurridos de Bogotá; para ello, se tomó una muestra de 161 pacientes y valorando cada parámetro de la escala, además, de comparar el puntaje dado por la misma y el diagnóstico histopatológico. Los resultados permiten concluir que la escala es sensible, pero no específica para el diagnóstico de apendicitis.

Acute abdominal pain is one of the symptoms which a patient attends the emergency room of any hospital worldwide, representing a 5 to 10% of those consultations; this represents for the emergency doctor and specialists interconsulted a challenge, because it contains several conditions that may or may not be surgical and not be diagnosed properly and promptly can be fatal, within these, is appendicitis, pathological and surgical condition which most often is faced the surgeon general. The patient may present with signs and varied symptoms ranging from a clear picture of appendicitis, or have no signs or symptoms suggestive as this pathology diagnosis; so scales have been developed to facilitate or provide help to the doctor for a correct diagnosis and subsequent treatment; Alvarado makes the scale of these diagnostic aids, being a non-invasive, fast and reliable economical method. Was evaluated by means of this project the validity of the scale in the USS Tunal IIII level to be one of the largest and busiest hospitals in Bogota, for this sample of 161 patients was taken Hospital and rated each parameter in addition to comparing the scores given by the same scale and histopathological diagnosis. The results show that the scale is sensitive but not specific for the diagnosis of appendicitis.

Regulation of ribosome biogenesis in maize embryonic axes during germination.

Ribosome biogenesis is a pre-requisite for cell growth and proliferation; it is however, a highly regulated process that consumes a great quantity of energy. It requires the coordinated production of rRNA, ribosomal proteins and non-ribosomal factors which participate in the processing and mobilization of the new ribosomes. Ribosome biogenesis has been studied in yeast and animals; however, there is little information about this process in plants. The objective of the present work was to study ribosome biogenesis in maize seeds during germination, a stage characterized for its fast growth, and the effect of insulin in this process. Insulin has been reported to accelerate germination and to induce seedling growth. It was observed that among the first events reactivated just after 3 h of imbibition are the rDNA transcription and the pre-rRNA processing and that insulin stimulates both of them (40-230%). The transcript of nucleolin, a protein which regulates rDNA transcription and pre-rRNA processing, is among the messages stored in quiescent dry seeds and it is mobilized into the polysomal fraction during the first hours of imbibition (6 h). In contrast, de novo ribosomal protein synthesis was low during the first hours of imbibition (3 and 6 h) increasing by 60 times in later stages (24 h). Insulin increased this synthesis (75%) at 24 h of imbibition; however, not all ribosomal proteins were similarly regulated. In this regard, an increase in RPS6 and RPL7 protein levels was observed, whereas RPL3 protein levels did not change even though its transcription was induced. Results show that ribosome biogenesis in the first stages of imbibition is carried out with newly synthesized rRNA and ribosomal proteins translated from stored mRNA.

Illness trajectories in Mexican children with juvenile idiopathic arthritis and their parents.

BACKGROUND: We hypothesize that the qualitative approach of socio-cultural aspects in children with juvenile idiopathic arthritis (JIA) and their parents would improve the understanding of their illness. OBJECTIVE: To explain the phenomenon of experiencing JIA within a specific cultural context. METHODS: The theoretical position of this research was based on the substantive theories of suffering, explanatory models and illness experience. Its design was that of qualitative field, and its analysis followed the interpretative grounded theory methodology. Data were collected by in-depth interviews and notes; tape recordings were transcribed verbatim, read and imported into the ATLAS/ti 4.2 software. Data conceptualization, categorization and interpretation were based on the constant comparison method. RESULTS: A total of 16 adults and six children from 10 families were interviewed. 'Pilgrimage' (metaphorically referred by some of the parents) was a major code in the study that reflected the religious reference to the trajectory of pain, faith and hope. For children, pilgrimage was conformed by immediate concepts; for parents, by historical and immediate experiences influenced by JIA subtype. Pilgrimage was consistent with the model of the illness trajectory theory, which conceptually relates to the idea that the course of chronic diseases is variable and modifiable throughout time. CONCLUSION: The qualitative approach of JIA provides wide and deep information on the perception that children and parents have about the disease. The illness trajectory theory corresponds to pilgrimage, the theoretical model for JIA in this study.

Condiciones de salud oral en ancianos residentes en hogares geriátricos de Asunción / Oral health conditions in elderly residents of nursing homes in Asuncion

La longevidad es una conquista de la humanidad, por lo tanto, la sociedad debe estar preparada para enfrentar los nuevos desafíos en lo que se refiere al ambiente, prácticas de salud y políticas sociales de atención al anciano, creando condiciones que posibiliten un envejecimiento saludable. Las Naciones Unidas clasifica dentro de la categoría de ancianos a las personas de 60 años y más, en el Paraguay este grupo de etario constituye alrededor del 73% de la población total. El envejecimiento es un proceso multicausal en el que intervienen numerosos factores que influyen en la cavidad bucal, al igual que el resto del organismo. La pérdida de piezas dentales no es propia de la edad, sino un indicador del mal estado de salud oral del paciente. En nuestro país no se tiene reporte de la situación de salud oral de los ancianos, por lo que se realizó es estudio observacional descriptivo de corte transverso, con el objetivo de observar clínicamente las condiciones de salud oral en personas mayores de 60 años residentes en hogares geriátricos de Asunción, con el propósito de establecer las condiciones y necesidades prioritarias y proponer un plan preventivo para mejorar dichas condiciones. Fueron examinados 46 pacientes, de ambos sexos, entre 60 y 92 años, residentes en hogares de ancianos "Nuestra Señora de la Asunción", "La Piedad" y "El Buen Samaritano", el muestreo fue no probabilístico de casos consecutivos. Entre los hallazgos más importantes se destacan la prevalencia de caries y enfermedad periodontal que fueron de 100% y el promedio de 4,4 piezas dentarias sanas presentes en boca. Por lo que se sugiere la realización de otro estudio para conocer la situación real en el país, la creación de una cátedra de odontogeriatría, para la atención especializada de los ancianos institucionalizados o no, y el establecimiento de medidas educativas tendientes a posibilitar un país con ancianos saludables

Enfermedad de Rosai-Dorfman / Rosai-Dorfman Disease

En esta comunicación se presenta un caso con compromiso de ambas fosas nasales por la enfermedad de Rosai-Dorfman. En el examen clínico se constataron sendas masas tumorales que ocupaban totalmente la fosa nasal derecha y, parcialmente, la izquierda. En el estudio histológico se comprobó la presencia de proliferación de linfocitos, varios de ellos cargados de núcleos linfoides sin desintegrarse, lo que constituye la emperipolesis. Esta histología concuerda con la enfermedad de Rosai-Dorfman. Esta paciente fue tratada quirúrgicamente realizándosele un abordaje combinado mediante rinotomía lateral y resección endoscópica nasal con microdebridador. Es importante destacar que constituye el primer caso reportado en Cuba en la localización nasal.

[Correlation between positive skin tests to molds, total IgE, and specific IgE using ELISA and mold cultures from the environment of the pediatric allergy patient]. / Correlación entre pruebas cutáneas positivas a hongos, IgE total, e IgE específica por ELISA y cultivos de hongos en el medio ambiente del paciente pediátrico alérgico.

The aim of this study was to made a correlation between allergic symptoms, positive skin prick test to fungi, total and specific IgE and mold culture in the patient's environmental. There were included 35 children (3-16 years), with skin prick test positive to fungi. The most frequent were: Rhizopus, Aspergillus, Cladosporium and Candida. Total and specific IgE were measured with ELISA, with titers high in 77.2% and 31.4% respectively. Fungal cultures were collected from dwellings and schools. The most frequently isolated mold genera were Cladosporium, Alternaria and Penicillium in the same proportion in both places: dwellings and schools. We concluded fungi are commonly found in children's environment.

[Antimicrobial susceptibility of Neisseria gonorrhoeae strains determined by disk diffusion]. / Susceptibilidad antimicrobiana de cepas de Neisseria gonorrhoeae por difusión con discos.

The Gonoccocus Laboratory of "Pedro Kourí" Tropical Medicine Institute carried out a study of in vitro susceptibility of Neisseria gonorrhoeae to penicillin, tetracycline, cefuroxime ceftriaxone, cefotaxine and ciprofoxacin by means of a disk diffusion method with the culture medium agar base GC plus supplement. In the first phase, the method was standardized and the reference N. gonorrhoeae ATCC 49226 strain was used whereas in the second phase, 50 gonococcal strains isolated in 8 provinces during 1995 and 1996 were examined. The results of such standardization confirmed that the antimicrobial susceptibility values were within the allowable limits. 52 and 34% of strains were resistant to penicillin and tetracycline respectively and all of them showed susceptibility to the rest of evaluated antimicrobial drugs. We recommend the use of the disk diffusion method for surveillance of gonococci resistance to these drugs in our country.

[First report of Neisseria polysaccharea in Cuba]. / Primer reporte de Neisseria polysaccharea en Cuba.

The National Laboratory of Reference of Pathogenic Neisserias of "Pedro Kourí" Tropical Medicine Institute studied 58 strains which had been previously identified as Neisseria meningiditis and isolated from nasopharyngeal carriers from 1985-1998. They were applied the knapp detection scheme plus the glutamiltransferase production test. The latter and the polyscharide production based on 5% sacarose allowed to make a differential diagnosis between N. meningitidis and Neisseria polyccharea. It was possible to identify a N. polysaccharia strain, a species that is reported for the first time in Cuba.

Capacidad de autocuidado de pacientes diabéticos no insulinodependientes / Self-care ability in non insulin-dependent diabetic patients

Uno de los mayores desafíos en el manejo de la diabetes, es lograr la adhesividad al tratamiento, haciéndose evidente la necesidad de educación para lograr la motivación y el compromiso del individuo. Es aquí donde la enfermería en su rol educativo adquiere un papel fundamental, pues busca entregar al paciente las habilidades necesarias para su autocuidado. Por ello, conocer las Capacidades de Autocuidado del paciente, es importante ya que de esta manera se podrán adaptar las estrategias a su condición, logrando su máxima independencia. El propósito del estudio es conocer la Capacidad de Autocuidado y el Motivo de Consulta al Servicio de Urgencia del hospital Dr. Sótero del Río, de diabéticos no insulinodependientes mayores de 45 años, durante Noviembre de 1997. Estudio descriptivo y transversal. La muestra se seleccionó de forma intencional y quedó constituida por 60 personas a quienes se les aplicó un cuestionario. De los resultados se destaca que un 41 por ciento de la muestra tenía nivel educacional. La causa más frecuente de consulta fue la diabetes descompensada. Se observó que un alto porcentaje de los pacientes tenía 6 años ó más con la enfermedad. En cuanto a las complicaciones crónicas un 70 por ciento tenía al menos una. Con relación a la capacidad de autocuidado de estos pacientes se concluyó que el 67 por ciento era independiente.

[Characterization of Haemophilus influenzae strains using sugar fermentation]. / Caracterización de cepas de Haemophilus influenzae mediante fermentación de azúcares.

64 Haemophilus influenzae strains circulating in Havana City during a year were characterized by the carbohydrate fermentation method for the first time in Cuba. The fermentative pattern D was the most frequently found. Patterns D and G together were 72% of the total of strains studied. The combination of the carbohydrate fermentation with serotyping and biotyping allowed a greater differentiation of strains (14 groups). Patterns A, B, C and F appeared in children over 6 months of age, and pattern G in the group from 6 to 18. Patterns D and G predominated in the bacterial meningoencephalitis. A higher heterogeneity was observed among the strains isolated from acute respiratory infections. Some of the advantages of the Haemophilus influenzae strains subtyping method are stressed, such as: simplicity, easiness to be applied and interpreted, and the fact that it is not necessary a qualified personnel or a specialized laboratory for its implementation.

[Arterial oxygen saturation versus peak expiratory flow as predictive values in the course of asthmatic crises in children]. / Saturación arterial de oxígeno contra flujo espiratorio máximo como valores predictivos en la evolución de la crisis asmática en niños.

Asthmatic crisis is one of the most frequent urgencies in children. One of the most difficult decision for a physician is to determine what patient requires only ambulatory treatment and what patient needs hospital treatment. Many investigators have developed predictive scores, but to date conclusions are confusing. The purpose of the present study was to compare the value of arterial oxygen saturation versus peak expiratory flow rate measurements as predictors of the outcome of the asthmatic crisis in children. We performed a prospective, longitudinal, observational, comparative study in 50 children (30 males, 20 female), with ages between 6 and 18 years old, with the presence of a moderate asthmatic crisis. We measured arterial oxygen saturation and peak expiratory flow rate at the moment of their arrival to urgencies and at 30 minutes, 2, 4 and 24 hours after the administration of nebulized albuterol (100 mcg/k/dose). We found significant differences on baseline arterial oxygen saturation and the registrations taken at 2, 4, and 24 hours posttreatment (0.01), and we could only find significant differences between baseline peak expiratory flow rate and the registrations taken at 24 hours pretreatment. In conclusion arterial oxygen saturation is a better predictor than peak expiratory flow rate in the evolution of the asthmatic crisis in children.

[Early identification of respiratory viruses in asthmatic children]. / Identificación temprana de virus respiratorios en niños asmáticos.

The role of viral infections as a part of the environmental factors that triggered asthma in atopic subjects, their age specific pattern, as well as many risk factors for the development of subsequent wheezing are described. Some pathogenic mechanisms and their importance in the induction of airway inflammation are mentioned and early identification by laboratory tests in outlined for preventive approach and early antiinflammatory treatment.

[Urethritis caused by serotype B Haemophilus influenzae. Report of a case]. / Uretritis por Haemophilus influenzae serotipo b. Reporte de un caso.

A case of a patient with schistosomiasis haematobium history, from Mozambique, is presented. This patient was admitted in the Institute of Tropical Medicine for having urination troubles and purulent urethral secretion. Serotype B Haemophilus influenzae, biotype i.v. of the urethra, was isolated. The strain was sensitive to ampicillin, chloramphenicol, ceftraxione, and norfloxacin, and resistant to tetracycline and erythromycin. The patient got better after receiving treatment with norfloxacin. A comment is made on the role of this microorganism as a sexual transmission pathogen.
