PREVALENCIA DE INFECCION POR VIRUS HEPATITIS C, B Y VIH EN PACIENTES ALCOHOLISTAS DE LA CIUDAD DE CORDOBA

La Hepatitis C y B, junto al alcoholismo, continúan siendo un verdadero problema de Salud Pública. Sin embargo, actualmente no existen datos locales que nos permitan estimar la prevalencia de infección por virus hepatotropos en pacientes alcoholistas, sus genotipos, distrubución geográfica, ni su asociación con determinado tipo de alcoholismo. Además, la co-infección del virus de la inmunodeficiencia humana (VIH) con los virus de hepatitis supone un impacto muy importante desde el punto de vista sanitario y estadístico en nuestro país, ya que alrededor del 50 por ciento de los pacientes VIH positivos presentan dicha coinfección. Es así que, por ser de interés sanitario y por compartir vías de transmisión con el virus de hepatitis B y C, nos parece adecuado estudiar también la presencia de VIH-1 en esta población. Nuestro centro de atención pública (IPAD), atiende a pacientes con trastornos por el consumo de sustancias; deshabitúa y rehabilita alcoholistas y a otros trastornos por consumo. Dichos pacientes, que viven en la ciudad capital, serán evaluados serológicamente para la detección de virus hepatotropos C-B y el VIH. Considerando que en nuestra institución se atiende a un 70 % de Alcoholistas Puros (con un promedio de 7 pacientes nuevos por día), nos resulta importante pesquisar la prevalencia de Virus C, B y VIH en nuestra población de alcoholistas. Toda esta problemática, es la propuesta de mi tesis doctoral. Hipótesis: estimamos encontrar en nuestra población de estudio cifras superiores a la prevalencia de estos virus publicada en bancos de sangre, lo cual se toma como referencia. Objetivos: -Conocer la prevalencia de infección por Virus de Hepatitis C, B y VIH-1 en pacientes alcoholistas de la ciudad de Córdoba, determinar si existe asociación de estos virus con algún tipo de alcoholismo, e identificar genotipos prevalentes y su distribución geográfica en Córdoba. Se incluirán en forma prospectiva y aleatorea, pacientes que concurren por primera vez, de ambos sexos, mayores de 21 años, alcoholistas puros (Gama-Delta-Epsilon de Jellinek). Se confeccionará una ficha, previo consentimiento informado, que permitirá categorizar al "tipo de bebedor". Se les realizará Serología para HCV, Ag HBs (en caso de reactividad se adicionará el Anti HBcore) y VIH. En caso de la positividad serológica, se procederá al frisado de los mismos, para la Genotipificación correspondiente. La recolección, captura y procesamiento de los datos se realizarán en una planilla o ficha. Luego se reubicarán en una base electrónica de datos y se harán los análisis estadísticos de los mismos. Resultados esperados: estimamos encontrar, coincidiendo con la bibliografía, un aumento en la prevalencia de estos virus. Creemos que pueden existir diferencias en los distintos tipos de alcoholismo debido a las diversas situaciones de riesgo a las que se exponen (más exposición en el Gama de Jellineck). Por esto esperamos encontrar un aumento en la prevalencia del Virus C, especialmente en el tipo consuetudinario (delta de Jellineck) por los trastornos nutritivos derivados del modo de consumo. Posiblemente esto pueda ser la llave de otros estudios que puedan esclarecer una vía de transmisión desconocida para este virus. De la misma manera, identificar los distintos genotipos existentes en nuestra ciudad y su distribución, y que como sabemos tiene implicancia en la evolución, y en los costos por el tiempo de tratamiento. Esta información será un aporte para programar medidas de vigilancia epidemiológica adecuada, elaborar estrategias preventivas además de aplicar el tratamiento correspondiente a los pacientes infectados que se detecten como tal durante el desarrollo del proyecto.

Age, growth and reproductive biology of Plaice, (Pleuronectes platessa L.) in Irish waters, 2003-2005

The current study presents data on age and growth for plaice (Pleuronectes platessa L.) sampled between November 2003 and February 2005 in ICES areas Via (northwest coast of Ireland), Vila (Irish Sea), Vllg (Celtic Sea), VDj (southwest coast of Ireland) and VHb (west coast of Ireland), and data on the reproductive biology and maturity of plaice in ICES area Vllb (west coast of Ireland). This is the first detailed account of the biology of plaice for some of these areas. It is intended that this study will improve understanding of the life cycle of plaice and help fisheries scientists to better predict the effect of fishing effort on Irish plaice stocks. The overall length range found for plaice was 9-51.99cm TL, with a length range of 9-5 lcm TL for females and 9-40cm for males. In all ICES areas the length range for female fish was larger than for male fish. The age range of plaice sampled during this study was 1 to 16 years. In all ICES areas females had a greater range in ages and fish in the larger age groups. From analysis of length and age data it was concluded that there was a significant difference (P=0.000) in growth rate of males and females between ICES areas sampled in March 2004. The highest rate of fishing mortality was determined for ICES area Via (F=1.06) and the lowest for ICES area Vila (F=0.56). In each ICES area male and female plaice have fully recruited to the population by age 4, with the exception of females in ICES area Via, for which a tr value of 5 years was determined. Length at first maturity (L50%) was determined to be 23cm and 21cm for males and females respectively. Age at first maturity (A50%) was determined to be 3 years for both males and females. It was found that males and females in ICES areas Vllb, Vila and Via are well above the length and age at first maturity when they are recruited to the fishery. In ICES area Vllb female plaice spawn from November to March, with peak spawning occurring in February, and male plaice spawn from November to April, with peak spawning occurring in November. Spawning females had an age range of 2 to 10 years and spawning males had an age range of 2 to 7 years. From the oocyte length frequency distributions, it was determined that the plaice is a determinate batch spawner. During this investigation a total of 177 ovaries and 127 testes were staged using both macroscopic and histological criteria. The overall percentage of maturity stages which compared favorably between the two assessment methods was 22.03% for female plaice and 37.80% for male plaice. In general, the findings of this study indicate that there was a very poor match between the macroscopic and histological assessment methods. Given that the histological determination of these stages is based on the observation of a distinct set of developmental features, it is expected that it would be more accurate to use histologically assessed gonads to calculate the annual percentage maturity assessment. The biology of plaice in the areas studied is compared with previous studies of plaice in Irish and European waters.

Avaliação intraoperatória e planejamento cirúrgico na cardiomiopatia hipertrófica

Paciente de 45 anos do sexo masculino, com diagnóstico de cardiomiopatia hipertrófica septal assimétrica, tendo sido submetido a implante de cardiodesfibrilador no passado. Apesar do tratamento clínico otimizado, evoluiu com progressiva deterioração clínica suscitando tratamento invasivo. Entretanto, não havia gradiente importante na via de saída do ventrículo esquerdo (VSVE) ao ecocardiograma de repouso e o teste provocativo com dobutamina foi inconclusivo por não atingir a frequência cardíaca preconizada. A avaliação intraoperatória com ecocardiograma transesofágico em uso de isoproterenol foi fundamental no diagnóstico de obstrução da VSVE. A miectomia septal foi realizada com sucesso e o paciente apresentou boa evolução pós-operatória.

The Effect of Activity-Based Payment on Dentists’ Activity: Evidence from a Natural Experiment in the UK National Health Service

The extent to which remuneration systems affect the behaviour of health care professionals is of considerable importance in the administration of publicly funded heath care systems. Using data across two jurisdictions in the United Kingdom, in only one of which remuneration was changed, we compare the extent of measured dental activity at the dentist level in order to ascertain the impact of moving to activity-based remuneration. We find that there are large and statistically significant increases in activity as dentists moved to the activity-based system and that a dentist’s previous form of contract is an important determinant of the magnitude of the effect. We also explore the extent to which dentists’ professional attitudes can explain differences in their activity and find that some aspects of self-reported attitudes are associated with observable differences in activity.
