    2017-12-01

    Full Text Available Introducción: Los estudios realizados sobre la educación de la sexualidad han permitido constatar que aún son insuficientes los conocimientos que poseen los adolescentes sobre aspectos relacionados con el tema, en especial los riesgos del aborto y su repercusión de manera desfavorable en la salud sexual. Objetivo: Determinar la percepción de riesgo en adolescentes relacionado con aborto por embarazos no deseados. Métodos: Estudio observacional descriptivo, transversal y prospectivo, se utilizaron encuestas y entrevistas, así como métodos estadísticos para el procesamiento de la información. El universo estuvo conformado por 354 adolescentes pertenecientes a los consultorios médicos 20, 28 y 30 del Grupo Básico de Trabajo 2 del policlínico Pedro Borrás Astorga, la muestra de 190 adolescentes se encontraron entre las edades de 14 a 18 años. Resultados: Se evidenció una tendencia de los jóvenes a practicar conductas sexuales precoces y riesgosas, lo que favorece el aumento creciente de la práctica del aborto, con insuficientes conocimientos y percepción de riesgo sobre las consecuencias y riesgos de una interrupción de embarazo, donde se encuentran debilitados el rol de los padres y el papel del personal de salud de las áreas donde pertenecen. Conclusiones: Se demostró que el proceso de educación para la salud muestra insuficiencias en cuanto a la creación de programas educativos más creativos que fomentan actividades de promoción y prevención de salud dirigidos a los adolescentes.

    El aborto recurrente se presenta entre el 1 y 7% de las parejas. Su etiología comprende factores genéticos, inmunológicos, anatómicos, hormonales, metabólicos, trombofílicos e infecciosos. Con el objetivo de establecer la frecuencia de mosaicismos de baja proporción en cromosomas sexuales, en una población de parejas con antecedente de aborto recurrente, se hizo un estudio citogenético prospectivo caso- control en 20 parejas, remitidas al Laboratorio de Biogenética del Centro Colombiano de Fe...

    2008-01-01

    Las vacunas de células diploides humanas (WI-38, MRC-5) tienen un origen éticamente objetable, dado que dichas células proceden de abortos provocados. Entre ellas destacan vacunas empleadas contra rubéola, sarampión, parotiditis, rabia, poliomielitis, viruela, hepatitis A, varicela y herpes zóster. Actualmente se encuentran en desarrollo otras vacunas cultivadas en células (293, PER.C6) transformadas mediante virus, procedentes de abortos. Entre ellas hay vacunas contra la gripe, virus respi...

  4. Prevalencia de la infección por virus de Epstein Barr (VEB en mujeres gestantes y con aborto, durante las primeras semanas de embarazo

    2013-12-01

    Full Text Available El virus de Epstein-Barr (VEB es un agente patógeno común para los humanos y su efecto en la infección vertical es poco estudiado. Durante el embarazo hay riesgo a contraer infecciones que afectan al feto. La infección adquirida antes del nacimiento ocasiona abortos, mortinatos, malformaciones, retraso en el crecimiento intrauterino, prematuridad y secuelas por infección postnatal crónica. Los efectos inmediatos o a largo plazo representan un problema a nivel mundial. Durante el embarazo se ha mostrado una prevalencia del 98% y aproximadamente el 40% de las embarazadas son susceptibles y transmitirán el virus al feto. Los actuales exámenes clínicos de rutina revelan pocos hallazgos específicos en la madre pues en su mayoría la infección por VEB tiene un curso asintomático. La poca efectividad en su tratamiento hace que la prevención y el diagnóstico sean de gran importancia. Se conoce que el VEB se mantiene latente en el 90% de los pacientes después de la infección primaria y que la infección puede ser reactivada debido a diversos factores como el estrés crónico, posiblemente debido a la disminución de la respuesta inmune celular. En la presente investigación se evaluó la prevalencia de la infección por VEB en mujeres gestantes y con aborto que se encontraban durante las primeras 15 semanas de embarazo. Las muestras de pacientes de la consulta de obstetricia en diferentes ambulatorios de los Municipios Libertador y Campo Elías del Estado Mérida y de mujeres en la sala de emergencia obstétrica del Instituto Autónomo Hospital Universitario de Los Andes (IAHULA que acudieron por aborto durante las primeras semanas, se analizaron con una prueba ELISA para la detecctar anticuerpos séricos de tipo IgG VCA-VEB que no discriminan entre una primoinfección y una infección pasada. El 35% de la población de estudio fueron 9 mujeres en gestación sin antecedente de aborto y el 65% corresponde a 17 mujeres que historia previa

    En este trabajo nos hemos centrado en el estudio de 8 polimorfismos relacionados con el metabolismo de las hormonas sexuales en el feto y su relación con los abortos espontáneos de causa desconocida, bajo la hipótesis de que un desequilibrio en la producción de hormonas sexuales en el feto está implicado en la interrupción de la gestación. Para ello se seleccionaron muestras de tejido fetal procedentes de abortos espontáneos de causa desconocida y se estudiaron varios polimorfismos de dos enz...

  6. Aborto recurrente

    Directory of Open Access Journals (Sweden)

    Y. Alejandro Manzur, Dr.

    2010-05-01

    Full Text Available Aproximadamente 1–3% de parejas en edad reproductiva experimentan 3 ó más abortos espontáneos consecutivos, lo que se define como aborto recurrente. La evaluación debe incluir una detallada historia clínica y examen físico, seguida de una serie de exámenes protocolizados destinados a detectar los factores más frecuentemente involucrados en esta patología (anatómico, cromosómico, inmunológico, endocrinológico y trombofílico. El manejo debe basarse en evidencias, evitando tratamientos experimentales o sin sustento científico, e incluyendo siempre un adecuado soporte emocional, tan necesario en estas parejas. A pesar de los esfuerzos por dilucidar los orígenes del aborto recurrente, sigue existiendo un 50% de casos sin causa aparente, los cuales suelen lograr tasas de embarazo exitoso de hasta 70% sin mediar tratamiento médico alguno.

  7. ABORTO NO INFECCIOSO EN CAPRINOS

    Directory of Open Access Journals (Sweden)

    Francisco J. Pastor

    2006-10-01

    Full Text Available Las pérdidas por abortos constituyen la principal falla reproductiva de los caprinos en sistemas extensivos donde se presenta una restricción alimenticia durante la gestación. Los abortos en estas condiciones suelen presentarse en más de la mitad de las cabras gestantes. El alto número de abortos en cabras en condiciones de escasez de forraje obedece a la particular estrategia reproductiva de la cabra, la cual “responde” al estímulo del macho cabrío, aun con bajas reservas corporales de energía, y una vez gestante, la cabra continúa o suspende la preñez, según la disponibilidad de nutrientes. Bajo condiciones intensivas y en diversas áreas geográficas, se presenta una mayor ocurrencia de abortos en cabras lecheras de origen Europeo, en comparación com cabras no lecheras (nativas. En climas templados poco extremosos, las cabras lecheras son menos propensas a abortar durante las épocas más calurosas del año, en comparacióncon las épocas más frías. La ausencia de cuernos, una pobre condición corporal, la gestación de más de un feto y la deficiencia de magnesio, cobre y selenio son factores importantes de riesgo de abortos en caprinos. La deficiencia de fósforo provoca también el aborto en caprinos, aunque esto sólo se ha demostrado forzando artificialmente esta deficiencia. Se han documentado además abortos en cabras tratadas com antihelmínticos y en animales que han consumido algunas plantas de zonas áridas con fitotoxinas. PALABRAS-CHAVE: Condición corporal, desnutrición, edad, peso corporal, plantas tóxicas.

    2009-01-01

    Introducción: Las consecuencias psiquiátricas del aborto inducido siguen siendo objeto de controversia. Las reacciones de cualquier mujer al descubrir que ha concebido pueden ser muy variables. El embarazo, inicialmente intencionado o no deseado, puede provocar estrés; y el aborto espontáneo puede acarrear sentimientos de pérdida y reacciones de duelo, por lo que no es de extrañar que el aborto inducido, con las implicaciones emocionales añadidas (sentimientos de alivio, vergüenza y culpa), s...

    Guadalupe Salas y Villagómez

    1998-01-01

    Full Text Available En este artículo se hace una medición indirecta del aborto en México, a través del modelo de Bongaarts, con el fin de observar la evolución del aborto inducido y, en segundo término, hacer una aproximación a la incidencia de este fenómeno en 1976,1979 y 1987. También se realiza una estimación de la mortalidad por aborto y de su comportamiento entre 1980 y 1990, para observar su tendencia en el periodo, señalar el peso relativo de las muertes por aborto con relación al resto de las causas de muerte materna y a su importancia dentro de la mortalidad general de las mujeres en edad reproductiva. Por último, se buscó obtener una correlación entre las tasas específicas de la mortalidad por aborto y las tasas específicas de fecundidad, con el fin de encontrar en qué grupos de edad se observa una mayor correlación.

  14. Algunas determinaciones del pregnandiol urinario en el aborto amenazante

    Directory of Open Access Journals (Sweden)

    Eudoro Castillo Vega

    1956-07-01

    Full Text Available El presente trabajo tiene por objeto hacer algunas "determinaciones del pregnandiol urinario en enfermas con síntomas evidentes de aborto amenazante", o bien, en enfermas en cuya historia anamnésica se encuentre el antecedente de uno o más abortos anteriores, así como también de partos prematuros y que, ni en los primeros ni en los últimos se haya encontrado una causa bien determinada. En lo posible, se han escogido pacientes con antecedente Serológico Negativo y de constitución topográfica anatómica, en cuanto a pelvis se refiere, normales. Es de lógica que, a una enferma con una desviación uterina o con un tumor pélvico, no se puede achacar el aborto a deficiencia de Progesterona o de cualquiera otra hormona, pues la causa es verdaderamente objetiva.

  15. Medicina, eugenesia y género: el aborto terapéutico en las mujeres con tuberculosis. Buenos Aires, 1920-1930

    Directory of Open Access Journals (Sweden)

    María Laura Rodríguez

    2018-01-01

    Full Text Available Se analiza el aborto terapéutico como un recurso médico orientado teóricamente a salvaguardar la salud y la vida de la mujer gestante enferma. El artículo se aproxima a esta problemática considerando la asociación entre “tisis y embarazo” a partir de discursos y experiencias clínicas publicadas por un conjunto de obstetras, ginecólogos y tisiólogos que trabajaban en los hospitales de la ciudad de Buenos Aires entre 1920 y 1930. Así, se abordan saberes, discursos, criterios y prácticas terapéuticas, que muestran cómo se fueron definiendo tendencias conservadoras respecto a la gestación y a los órganos genésicos femeninos, bajo una agenda eugénica positiva que no priorizó la salud de estas enfermas. El texto muestra de qué manera dichas tendencias se moldearon a partir de valores y normativas anclados en la desigualdad de género.

  16. El aborto inducido de las mexicanas en el contexto transfronterizo México-Estados Unidos

    2003-01-01

    Full Text Available Este es un estudio sociodemográfico comparativo del aborto inducido de las mujeres que viven en los dos lados de la frontera México-Estados Unidos. Se analiza el caso especifico de Tijuana y San Diego mediante la utilización de fuentes complementarias de datos: una encuesta posparto realizada en el IMSS de Tijuana en 1993 con información para un total de 2 709 mujeres y los expedientes de la clínica Womancare de Planned Parenthood, con información para 1 109 mujeres. Esta última fuente incluye información sobre las mexicanas que cruzaron la frontera entre la primavera y el verano de 1993 para practicarse un aborto en condiciones legales y seguras en San Diego. Los resultados indican que el aborto ocurre más frecuentemente en las etapas avanzadas del periodo reproductivo de las mujeres. Sin embargo, también utilizan el aborto para posponer el inicio de su trayectoria reproductiva. Existen distintos patrones de aborto entre las mujeres fronterizas definidos por variaciones en la edad al momento del aborto, el número de hijos al momento de abortar, la edad al primer embarazo, las opiniones acerca del aborto, los motivos para abortar y los planes para enfrentar los efectos emocionales en la etapa postaborto.

    2008-01-01

    Tratar adecuadamente en el actual contexto plural la cuestión del aborto, no es oportuno centrarla en torno a los términos matar y no matar, o justo e injusto, sino más bien en un conflicto de valores y de su jerarquización. En ninguna concepción el aborto es un bien, y el reconocimiento del derecho al aborto no implica nunca la obligación de abortar.

  5. Aborto terapéutico, ausencia injustificada en la política sanitaria

    Directory of Open Access Journals (Sweden)

    Susana Chávez-Alvarado

    Full Text Available A pesar de que el aborto, por razones de salud, no es considerado un delito en el Perú, el Estado niega su inclusión en la política pública, con lo cual infringe el derecho de las mujeres a interrumpir un embarazo cuando este afecta su salud. Al examinar el artículo del Código Penal que exceptúa de delito a este tipo de aborto, se identifican atribuciones que protegen a las mujeres y establecen condiciones para ofertar dicha atención. En el presente documento se pone en debate los argumentos que el Estado Peruano viene usando para no aprobar el Protocolo de Aborto Terapéutico, con el cual se reglamentaria su oferta y financiamiento en los servicios públicos y se fundamenta por qué se debería cumplir con esta obligación, en base al marco conceptual de la “causal salud”. Se presentan, además, dos casos judicializados, en que el Estado Peruano ha sido encontrado responsable de violar los derechos humanos de dos adolescentes a quienes se les negó el aborto terapéutico.

    2011-01-01

    Full Text Available El comienzo de la vida humana se encuentra en vilo en Colombia, ante la ratificación del Protocolo Facultativo sobre la eliminación de todas las formas de discriminación contra la mujer, adoptada por la Asamblea General de las Naciones Unidas de 1999, ratificada en el año de 2005. El tema se desarrolla en dos Sentencias, la primera, C-355 de 2006 despenaliza el aborto en tres situaciones excepcionales: Violación, enfermedad de la madre y malformación del feto. La segunda, T-388 de 2009 abarca la objeción de conciencia, que solamente es reconocida a las personas naturales; afirmando el máximo Tribunal Constitucional que no es un derecho del cual sean titulares las personas jurídicas o el Estado, limitando a las clínicas, hospitales y centros de salud que presenten objeción de conciencia para la no realización de la práctica del aborto. El no cumplimiento de esta declaración ha producido sanciones a las instituciones sanitarias privadas por el no acatamiento de los efectos erga ommes de las sentencias proferidas por la Corte Constitucional; estas instituciones reclaman objeción de conciencia institucional por su ideario y creencias religiosas. Estos criterios tienen implicaciones bioéticas y biojurídicas frente a la interpretación pluralista de orden filosófico, religioso y jurídico del artículo 18 de la Carta Política; el cual, garantiza la libertad de conciencia en nuestro Estado Social de Derecho y, es el legislador quien debe reasumir su competencia a través del bioderecho.

    Full Text Available Se examinan varios aspectos relativos a las políticas de control de natalidad y respecto al aborto a la luz de algunas actitudes sociales y de algunos hechos. Las estadísticas anuales de 1976 muestran un total de 13.670 abortos realizados en España en 1974. Estadísticas no oficiales estiman sin embargo que son 400.000 los abortos realizados en España cada año; otras sugieren entre 70.000 y 100.000. Las leyes españolas permiten el aborto provocado tan sólo bajo circunstancias médicas especiales. Se citan las opiniones de médicos expertos y científicos favorables al aborto y al control de natalidad. Se ofrecen los precedentes legales de la política demográfica en España, y las leyes vigentes en otros países (incluyendo Europa Occidental, Gran Bretaña, Europa del Este, Canadá, Latinoamérica, Asía, África y Oceanía son revisadas. Se discute también la perspectiva moral basada en los derechos del feto, la posición de la iglesia católica y de los partidos políticos españoles. El Partido Socialista y el Partido Comunistas son favorables al aborto, mientras que alianza Popular y el Centro Democrático y Social se oponen al mismo. La Plataforma de Grupos de Mujeres de Madrid ha solicitado información y educativa en temas de sexualidad, anticonceptivos gratuitos y legalización del aborto en una campaña de presión a los partidos políticos llevada acabo con motivo de las elecciones de junio de 1977. Sin embargo, el III Congreso Nacional de la Familia Española ha manifestado en un informe estar a favor de los valores de la familia tradicional y su visión negativa del aborto y del uso de anticonceptivos, los cuales son emparejados a la permisividad social, al rechazo del principio de autoridad y a la trasgresión de la ley.

    2011-01-01

    Full Text Available El aborto inducido y la violencia doméstica contra las mujeres se consideran problemas de salud pública por las consecuencias a la salud física y mental que afectan a las mismas. El objetivo fue analizar el discurso de las mujeres que han experimentado el aborto en sus relaciones familiares. Los sujetos del estudio fueron diecisiete mujeres ingresadas en una maternidad pública en Salvador, Bahia (Brasil, por causa del aborto inducido. La recolección de datos se realizó entre julio y septiembre de 2008, por medio de entrevistas semiestructuradas, organizadas a partir del Discurso del Sujeto Colectivo. Las ideas centrales que surgieron de los discursos muestran que la decisión del aborto se deriva de la historia de violencia vivida con sus compañeros y familiares, y del abandono cuando el embarazo fue descubierto. La Enfermería necesita entender el contexto social en el cual viven las mujeres que abortan, a fin de reformular sus prácticas.

Los datos provienen de una encuesta anónima y computarizada a participantes que acudieron a una reunión de gineco-obstetricia en México en 2009 (n=418. Las actitudes de los profesionales de la salud juegan un papel determinante para favorecer el acceso a servicios de abortos tanto médicos como quirúrgicos. No se encontró asociación estadística entre vivir en una entidad federativa mayormente res- trictiva y la práctica de abortos, lo cual se explica por el escaso conocimiento que los participantes de la encuesta tenían sobre las leyes de aborto vigentes en su entidad. Esta falta de conocimiento sobre la legislación del aborto puede obstaculizar que una mujer tenga este servicio aun cuando el marco legal lo permita.

    Full Text Available Últimamente la investigación ha prestado un gran interés a la historia de género, siendo un tema ampliamente tratado el del control demográfico, pero se ha centrado más en la existencia y efectividad de los métodos usados que en el significado que esconde. Al analizar el tema del aborto y la anticoncepción en el mundo antiguo, en sociedades donde se acepta tranquilamente el infanticidio, analizaremos la relación de la maternidad con la ciudadanía femenina, así como la importancia dada a la reproducción, tanto la meramente física como la de todo el orden social que conlleva. Para ello se hace necesario analizar no solo las obras médicas o legales que hacen referencia al aborto, sino toda una serie de textos vinculados a la construcción de lo femenino en la Antigüedad. La ambigua relación entre maternidad, aborto e infanticidio nos ayuda a comprender mejor a la mujer antigua, pero también su sociedad e incluso la nuestra.

Muchas mujeres españolas podrían estar yendo a abortar a otros países europeos como Gran Bretaña, Francia u Holanda. Se ofrecen las estadísticas sobre aborto de estos países europeos. Se comparan las actitudes de los españoles hacia al aborto, y se comparan con las existentes en otros países. Se examina la planificación familiar en tanto que alternativa. Los datos recabados en España muestran que la mayoría de la población acepta la necesidad de implantar la planificación familiar, manifestándose asimismo a favor del uso de anticonceptivos orales como medio para llevarla a cabo. Entre las mujeres entrevistadas, un 30-35% afirmaron haber ingerido anticonceptivos orales para evitar el embarazo.

    Full Text Available Investigación cualitativa dirigida a comprender la vida cotidiana de las mujeres con un historial de violencia doméstica que tuvo un aborto. Se realizaron entrevistas en profundidad con diez mujeres que fueron ingresados en el hospital por el aborto y reportaron haber experimentado violencia doméstica. En la mayor parte, se caracterizan por ser negras, de bajo nivel educativo y con edad entre 18 y 40 años. El proceso de organización y análisis de los datos fueron basados en las nociones de la Sociología Comprensiva y la sensibilidad teórica. La vida de las mujeres que tuvieron un aborto está marcada por la experiencia de la violencia doméstica cuando niña y adolescente, expresado por el abandono y el rechazo, y también por la violencia doméstica. La actividad sexual temprana está relacionada con el embarazo no deseado y la falta de apoyo de la familia y de la pareja. Es necesaria una visión profesional para el reconocimiento de la violencia doméstica como un problema de salud de la mujer.

El artículo analiza la posición oficial de la jerarquía de la Iglesia Católica argentina difundida y defendida a través de los pronunciamientos públicos de la Conferencia Episcopal Argentina (CEA y las actitudes de ciudadanos/as cordobeses en relación al aborto. Se ha combinado técnicas de recolección y análisis de datos cualitativos y cuantitativos con el objeto de aproximarnos a una visión desde las jerarquías y las bases de un sector religioso mayoritario.

La muestra estuvo conformada por 30 pacientes de la Clínica de los Andes de Tunja, entre los 30 y 65 años. Se evaluaron los datos antropométricos, la frecuencia de consumo de alimentos y el perfil lipídico. Se les suministró a los pacientes 250 g de aguacate al día por cuatro semanas. Se empleó la estadística descriptiva y la prueba T de hipótesis con un nivel de significancia p< 0.05. Durante las cuatro semanas el aumento de peso de los hombres fue de 2.7 K y de las mujeres de 2.3 K (p<0.05. El nivel de colesterol total disminuyó en 14% (p<0.05 y el de LDL en 16% (P<0.05; el valor de HDL aumentó en un 19% (P<0.05, y el de los TG en un 12% (p =0.037. El 27% de la muestra normalizó los niveles de CT, el 30% los de LDL, el 91% aumentó el nivel de HDL y el 20% aumentó los de TG. El índice de riesgo de presentar enfermedad cardiovascular (CT/ HDL disminuyó en 29%. Según el test de Framinghan, 4 pacientes presentan más de un 20% de riesgo a 10 años de presentar cardiopatía coronaria. Los resultados muestran que el aguacate como fuente de ácidos grasos monoinsaturados, puede ser utilizado dentro del plan de alimentación de pacientes con dislipidemia, incluyéndolo dentro del aporte energético para evitar así un aumento de peso por su alta densidad calórica. En conclusión, en la población estudiada se evidenció el efecto benéfico del consumo diario de aguacate en términos de disminución de los niveles de colesterol total y LDL yaumento de HDL, resultados que tienen implicaciones como medida preventiva de la enfermedad coronaria.

    Full Text Available Introducción: se hace una revisión sobre el aborto, poniendo de manifiesto como el delito criminal ha evolucionado a la legitimidad destacando las posiciones de la Iglesia Católica, que eleva al feto a la categoría de persona antes de tener vialidad. Objetivo: valorar la situación legal en Cuba, amparado por la Resolución 24 del 2013 del Ministro de Salud que lo regula reconociendo a la grávida ese derecho. Material y método: se utilizan en el estudio métodos descriptivos, histórico lógico, estadísticos y demográficos. Se revisaron las tasas de abortos por embarazos comparativas del período de estudio que abarcaron los años desde 1970 a 2013 en la provincia Pinar del Río relacionadas con la natalidad. Conclusiones: el aborto en Cuba está reconocido como derecho femenino. Se rodea de cuidados científicos y éticos. Se practica en instituciones de salud y relaciona con la disminución de natalidad; resulta necesaria una nueva orientación educativa que contenga los valores que la reproducción implica para la salvaguarda de la salud de la mujer, y de la sociedad por sobre los intereses y motivos placenteros personales desligados de la utilidad social de cuanto hacemos con nuestras vidas.

In contrast, an HRE approach predicts decreased effectiveness due to repeated presentation. We ar...

    Estamos en los finales del presente siglo y hemos sido testigos de las inmensas conquistas obtenidas por los grandes avances de la ciencia y la tecnología modernas en todas las áreas del conocimiento humano. Sin embargo, por las perspectivas que logramos vislumbrar, llegaremos al año 2.000 sin darle una justa y real solución a la endemia mundial de la indeseable práctica del aborto que viene cabalgando a través de la historia universal.

    He considerado pertinente hacer algunas reflexiones sobre este inquietante y polémico tema, en mi doble función de Rector de la Universidad Metropolitana, especializada como es sabido en el área de la salud, y en mi condición de especialista en Gineco-Obstetricia con un largo recorrido de más de seis lustros en actividad permanente a la que he dedicado tiempo completo, tanto en la práctica hospitalaria como privada.

    Esta endemia mundial del aborto es tan antigua como la misma historia de los pueblos, así observamos que las leyes de la antigua India no penalizaban la interrupción del embarazo. En la Grecia antigua no se le miraba como un acto deshonesto. En Roma tanto en la época imperial como en la República no era considerado como delito y solamente con la llegada del cristianismo pasó a convertirse en un hecho punible: a partir de entonces cada nación de acuerdo con su cultura o religión fue tomando una posición frente a esta indeseable práctica.

    Cada vez que se menciona la palabra aborto o se pone en boca de algún representante de la sociedad o de cualquier gobierno, genera encendidas polémicas y a veces hasta cismas en la opinión de los pueblos. En Colombia el problema de la práctica del aborto clandestino es un mal social grave con grandes repercusiones en la salud de la comunidad y en los servicios médicos asistenciales, especialmente en la población de escasos recursos económicos.

    Full Text Available La dimensión subjetiva implicada en el proceso de aborto voluntario en contextos de ilegalidad y penalización ha sido escasamente explorada. Cuando un aborto se produce en la clandestinidad es, por definición, un aborto inseguro, independientemente de las condiciones sanitarias en el cual éste tenga lugar. El contexto de ilegalidad y penalización se transforma en un texto que determina la experiencia y sus resultados médicos, psicológicos, familiares, sociales y jurídicos. El estudio se realizó en base a un diseño cualitativo con entrevistas en profundidad a mujeres que abortaron clandestinamente en los últimos 15 años en Uruguay. Los hallazgos permitieron conocer los factores subjetivos asociados a las experiencias de aborto en un contexto, como el uruguayo, donde la práctica es tipificada como delito por la ley vigente en el país. The subjective dimension involved in the process of voluntary abortion in contexts of illegality and criminalization hasn't been studied in depth. A clandestine abortion is, by definition, an unsafe abortion, regardless of the sanitary conditions under which it takes place. The context of illegality and criminalization turns into a text that determines the experience and the medical, psychological, family, social and legal outcome. The study was carried out on the basis of a qualitative design with in-depth interviews to women who underwent clandestine abortions in the past 15 years in Uruguay. The findings allowed for the discovery of the subjective factors associated to abortion experiences in a context, such as the Uruguayan, where the practice is defined as a crime by the law in force.

    Full Text Available El aborto ha sido siempre un tema complejo que, en la actualidad, sigue suscitando intensos debates desde planteamientos muy dispares y posturas irreconciliables. Detrás de las diferentes líneas argumentativas para legitimar o no la interrupción voluntaria de la gestación existe un análisis de salud sexual y reproductiva desde una óptica moral con una concepción determinada de la “maternidad” que condiciona la jurisprudencia de los diferentes países. Muchas legislaciones permiten el aborto por cuestiones de salud, pero la defensa de la libertad de las mujeres lo reivindica como un derecho humano. Abortion has been always a complex subject still carries on causing heated discussions from very disparate criteria and irreconcilable positions. Behind the different argumentative lines to legitimate, or not, the voluntary termination of pregnancy, there is an analysis on sexual and reproductive health from a moral viewpoint with a certain conception of “motherhood” that conditions all countries’ jurisprudence. Many legislations authorize abortion on heath matters, but the defense of the women’s freedom demands it as a human right.

    Full Text Available In this paper we propose an integrative model of habituation of reinforcer effectiveness (HRE that links behavioral and neural based explanations of reinforcement. We argue that habituation of reinforcer effectiveness (HRE is a fundamental property of reinforcing stimuli. Most reinforcement models implicitly suggest that the effectiveness of a reinforcer is stable across repeated presentations. In contrast, an HRE approach predicts decreased effectiveness due to repeated presentation. We argue that repeated presentation of reinforcing stimuli decreases their effectiveness and that these decreases are described by the behavioral characteristics of habituation (McSweeney and Murphy, 2009;Rankin et al., 2009. We describe a neural model that postulates a positive association between dopamine neurotransmission and HRE. We present evidence that stimulant drugs, which artificially increase dopamine neurotransmission, disrupt (slow normally occurring HRE and also provide evidence that stimulant drugs have differential effects on operant responding maintained by reinforcers with rapid vs. slow HRE rates. We hypothesize that abnormal HRE due to genetic and/or environmental factors may underlie some behavioral disorders. For example, recent research indicates that slow-HRE is predictive of obesity. In contrast ADHD may reflect ‘accelerated-HRE’. Consideration of HRE is important for the development of effective reinforcement based treatments. Finally, we point out that most of the reinforcing stimuli that regulate daily behavior are non-consumable environmental/social reinforcers which have rapid-HRE. The almost exclusive use of consumable reinforcers with slow-HRE in pre-clinical studies with animals may have caused the importance of HRE to be overlooked. Further study of reinforcing stimuli with rapid-HRE is needed in order to understand how habituation and reinforcement interact and regulate behavior.

    Full Text Available El uso del mifepriston (RU486, en combinación con análogos de las prostaglandinas, en la inducción del aborto químico requiere una específica reflexión en relación a los principales aspectos farmacológicos y toxicológicos. La actual dialéctica bioética y biopolítica, a menudo ideologizada, impone aún más un tratamiento riguroso basado en evidencias científicas, para aclarar sobre todo los mecanismos de acción y de los eventos adversos. Estos últimos a veces también subvalorados o minimizados. Considerada la iniquidad del aborto voluntario, el artículo se propone también el objetivo de aclarar cómo, a la luz de una reciente bibliografía, el recurso al RU486 representa un significativo riesgo para la salud de las mujeres. Una particular atención está reservada a la aclaración etiopatogenética de las hemorragias y de las sepsis, en las cuales se han evidenciado también distintos decesos.

Aquí se describe un caso de aborto en yegua debido a la infección por este agente. Se efectuó la necropsia completa de un feto a término donde se colectaron muestras para inmunofluorescencia directa (IFD, histopatología y microbiología. Además, se efectuó un estudio serológico de la tropilla y se evaluó seroconversión en la yegua abortada. El feto evidenció hepatomegalia, esplenomegalia e ictericia. Microscópicamente se apreció hepatitis mononuclear con disociación de los hepatocitos, esplenitis aguda y glomérulo-nefritis. Aunque el microrganismo no pudo ser aislado, la enfermedad se confirmó por la seroconversión observada en la yegua abortada, y debido a la identificación del agente mediante IFD en la impronta renal. Este caso demuestra la presencia del agente localmente y evidencia que la enfermedad puede ser un problema para la producción ecuestre. SUMMARY. Abortion caused by Leptospira in a mare from Salta Province, Argentina. Leptospirosis in horses is usually asymptomatic, although there are regions where the disease is a problem. Here, a case of abortion caused by the agent in a mare is described. Full autopsy of a fetus at term was performed; samples for direct immunofluorescence (DIF, histopathology and microbiology were collected. Additionally, a serological study of the herd was conducted, as well as seroconversion in the aborted mare. The fetus evidenced hepatomegaly, splenomegaly and jaundice. Microscopically, mononuclear hepatitis with hepatocyte dissociation, acute splenitis and glomerulonephritis, were appreciated. Although the microorganism couldn’t be quite properly, the disease was confirmed by the seroconversion present in the aborted mare.

O material utilizado foi obtido de um estudo retrospectivo de casos de aborto recebidos pelo Setor de Patologia Veterinária da Universidade Federal de Lavras e de fetos necropsiados durante os anos de 2011 a 2013. De 60 fetos estudados, 30 (50% tinham lesões microscópicas. Destes, 19 (63% apresentaram lesões compatíveis com aborto por N. caninum, caracterizadas principalmente por encefalite não supurativa multifocal, necrose e gliose multifocal, assim como, miocardite e miosite não supurativa. Em 14 fetos chegou-se ao diagnóstico definitivo. Destes, cinco tiveram sua confirmação somente pela marcação IHQ e cinco foram positivos somente na PCR. Quatro fetos foram positivos tanto na IHQ quanto na PCR. Cinco fetos, provenientes do estudo retrospectivo apresentaram lesões compatíveis com N. caninum, mas a presença do protozoário não foi confirmada pela marcação IHQ. Os achados demonstram que o N. caninum é um importante agente associado ao aborto em bovinos na região sul de Minas Gerais. Para tanto, além das lesões microscópicas a associação entre a IHQ e a técnica de PCR foi essencial para a confirmação do diagnóstico.

    Full Text Available Con el presente trabajo se pretende incorporar al estudio del aborto en México la perspectiva generacional y la distinción según el tipo de unión, dos dimensiones que no han sido consideradas en los estudios publicados hasta la fecha. Los datos utilizados corresponden a los de la Encuesta Nacional de la Dinámica Demográfica levantada en 1997. Entre los resultados obtenidos destaca el relativo a la reducción que experimentó el aborto entre las jóvenes (menores de 30 años de las generaciones nacidas a fines de los años cuarenta y aquellas que lo hicieron veinte años después, a fines de los sesenta. La distinción por tipo de unión nos permite atribuir esta disminución a las mujeres casadas, que casi exclusivamente eran quienes lo practicaban, y evaluar su impacto reductivo sobre la fecundidad en 1.2 nacimientos evitados en las generaciones mayores y 0.5 en las mas jóvenes. Las mujeres en uniones libres no superan los 0.6 nacimientos evitados en ninguna de las dos generaciones. Al aplicar el factor de separación propuesto, estas diferencias se traducen en relaciones de un aborto espontáneo por casi seis inducidos entre las casadas de más edad y solamente uno de cada dos entre las más jóvenes. Finalmente la distribución según el método anticonceptivo utilizado nos indica que las jóvenes en unión libre están más eficazmente protegidas que las casadas.

  13. Habituation of the cold shock response is inhibited by repeated anxiety: Implications for safety behaviour on accidental cold water immersions.

    Accidental cold-water immersion (CWI) triggers the life-threatening cold shock response (CSR) which is a precursor to sudden death on immersion. One practical means of reducing the CSR is to induce an habituation by undergoing repeated short CWIs. Habituation of the CSR is known to be partially reversed by the concomitant experience of acute anxiety, raising the possibility that repeated anxiety could prevent CSR habituation; we tested this hypothesis. Sixteen participants (12 male, 4 female) completed seven, seven-minute immersions in to cold water (15°C). Immersion one acted as a control (CON1). During immersions two to five, which would ordinarily induce an habituation, anxiety levels were repeatedly increased (CWI-ANX rep ) by deception and a demanding mathematical task. Immersions six and seven were counter-balanced with another high anxiety condition (CWI-ANX rep ) or a further control (CON2). Anxiety (20cm visual analogue scale) and cardiorespiratory responses (cardiac frequency [f c ], respiratory frequency [f R ], tidal volume [V T ], minute ventilation [V̇ E ]) were measured. Comparisons were made between experimental immersions (CON1, final CWI-ANX rep , CON2), across habituation immersions and with data from a previous study. Anxiety levels were sustained at a similar level throughout the experimental and habituation immersions (mean [SD] CON1: 7.0 [4.0] cm; CON2: 5.8 [5.2] cm cf CWI-ANX rep : 7.3 [5.5] cm; p>0.05). This culminated in failure of the CSR to habituate even when anxiety levels were not manipulated (i.e. CON2). These data were different (pCSR consequently habituated. Repeated anxiety prevented CSR habituation. A protective strategy that includes inducing habituation for those at risk should include techniques to lower anxiety associated with the immersion event or habituation may not be beneficial in the emergency scenario.

    Full Text Available http://dx.doi.org/10.1590/S0104-026X2012000100010 La ley de “matrimonio igualitario”, votada en 2010 por el parlamento argentino, convirtió a este país en el primero de Latinoamérica en legalizar el matrimonio homosexual. Se trata de una victoria para un grupo históricamente discriminado por sus preferencias eróticas y hasta entonces ausente de la legislación. En este contexto, aparentemente auspicioso para la igualdad sexual, considero, sin embargo, que la nueva ley no se corresponde con el orden sexual que regula los cuerpos de las mujeres argentinas. En efecto, desde 1921 el Código Penal argentino tipifica al aborto como un “delito contra la vida” y, pese a ello, cada año unas cien mujeres mueren por abortos clandestinos. En base a esta situación, en este artículo analizaré el desfasaje que encuentro entre las políticas homosexuales y las políticas reproductivas de Argentina. A diferencia de Europa, donde los derechos reproductivos precedieron a las políticas homosexuales, en este país se ha operado lo inverso. Allí, el reconocimiento legal de las parejas de mismo sexo coincide con las medidas impulsadas por otras democracias, tendientes a alcanzar lo que algunos autores denominan ciudadanía sexual. Sin embargo, mientras la Argentina no reconozca el derecho a la interrupción gratuita y segura del embarazo, esta noción, que legitima la aplicabilidad universal de derechos sexuales, seguirá siendo problemática. Considero que sin el derecho a la libre disposición del propio cuerpo, el cual comprende la libertad sexual y el derecho a decidir sobre la gestación, en el actual contexto argentino la ley de matrimonio gay representa un episodio aislado.

    Neurodevelopment outcomes of children conceived by Assisted Reproductive Technology (ART)have been the subject of much recent attention. To date there are no reports of neurodevelopmental performance before birth in this group. To compare habituation (a measure of brain function) in fetuses conceived by assisted reproduction techniques (ART) with naturally conceived (NC) fetuses. Case control study. Women with singleton pregnancies matched for maternal age, parity and smoking were recruited in 2 groups: ART (n=20) and NC (n=20). Sound stimuli (250 Hz, 110 dB) at 10 second intervals lasting 2 s were administered to the fetus. The end point was habituation (cessation of movement for five consecutive stimuli) or a maximum of 30 stimuli. Responses of the fetus were observed with ultrasound at 28, 32 and 36 weeks' gestation, video-recorded and anonymised for analysis. At 28 weeks' gestation significantly more ART fetuses responded to sound of 250 Hz, 110 dB (p=0.02) but this difference did not persist at 32 and 36 weeks'. There was a significant increase in nonresponders as gestation advanced in the ART group. There was no difference in habituation or mean number of trials to habituate at all three gestations. ART fetuses demonstrated no differences in habituation suggesting that there is no neurodevelopment delay. However, a decrease in response to sound as gestation advances might be a harbinger for poor perinatal outcomes and needs exploration. Crown Copyright © 2011. Published by Elsevier Ireland Ltd.

    The autonomic nervous system in Behcet's patients may be affected due to various reasons. This entity may be detected with the measurement of the electrodermal activities, heart rate variability and pupillometric methods. Habituation is one of the implicit forms of learning and memory and the loss of habituation can reveal pathological changes in the synaptic regions. To determine whether there is a functional decrease in the synaptic effectiveness (habituation) of the pathways to sympathetic neurons that had been repeatedly activated in Behcet's. Twelve patients with Behcet's disease and 12 healthy controls were included in the study. Sympathetic skin potential (SSP) records were taken at normal room temperature in a quiet place within a Faraday cage. Sixteen square wave single shock impulses (duration: 1200 ms, strength: 5 mA) were applied on each case. After the 1st stimulus, the SSP amplitudes were lower in the patients compared to the controls (P0.05). Whereas there was no significant differences among the SSP amplitudes after the 9th impulse in the controls (P>0.05). The habituation rate of the SSP after consecutive impulses was slowest in the patients compared to controls (P<0.001, t value=12.39). There is a delayed habituation in Behcet's disease and that may due to pathologic changes with vasculitis through their peripheral nerves.

  7. Mortalidade por causas relacionadas ao aborto no Brasil: declínio e desigualdades espaciais

    2000-03-01

    Full Text Available Além de constituir causa freqüente de internamentos obstétricos em países pobres, o aborto representa a incapacidade do sistema público de saúde de prover informação suficiente sobre métodos contraceptivos para prevenir gestações em vez de interrompê-las. No Brasil, as altas taxas de utilização de serviços de saúde por abortamentos refletem as dificuldades persistentes de contracepção e planejamento familiar. Além disso, a mortalidade por aborto serve como indicador da qualidade dos procedimentos abortivos, um ponto importante num país onde tal prática é ilegal e, portanto, clandestinamente realizada. No presente estudo, analisamos as taxas de mortalidade por causas relacionadas ao aborto entre mulheres de 10 a 54 anos de idade, incluindo aquelas que morreram por abortamentos espontâneos e provocados, de 1980 a 1995, segundo região de residência. As informações utilizadas foram obtidas do banco de dados sobre mortalidade do Sistema Único de Saúde --Ministério da Saúde. Dados sobre população foram obtidos junto à Fundação Instituto Brasileiro de Geografia e Estatística. Estudaram-se 2 602 óbitos. Do total de óbitos, 15% foram devidos a aborto retido, aborto espontâneo e aborto induzido com indicação legalmente admitida. Oitenta e cinco por cento dos óbitos foram causados por aborto induzido sem indicação legalmente admitida e por aborto sem causa especificada. Os coeficientes de mortalidade por causas relacionadas ao aborto têm decrescido continuamente no Brasil, mas tais avanços têm-se distribuído desigualmente no país. A região que apresentou a menor queda na taxa (38% em 15 anos foi o Nordeste. As mulheres que morreram por aborto tiveram uma média de idade decrescente no período estudado.

  8. Sleep homeostasis, habits and habituation.

    2017-06-01

    The importance of sleep for behavioural performance during waking is long-established, but the underlying reasons and mechanisms remain elusive. Waking and sleep are associated with changes in the levels of GluA1 AMPAR subunit in synaptic membranes, while studies using genetically-modified mice have identified an important role for GluA1-dependent synaptic plasticity in a non-associative form of memory that underlies short-term habituation to recently experienced stimuli. Here we posit that sleep may play a role in dishabituation, which restores attentional capacity and maximises the readiness of the animal for learning and goal-directed behaviour during subsequent wakefulness. Furthermore we suggest that sleep disturbance may fundamentally change the nature of behaviour, making it more model-free and habitual as a result of reduced attentional capacity.

    Full Text Available ResumenEste trabajo se plantea a partir de una perspectiva teórico–conceptual, en la cual se aborda la relación entre dos enfoques que confluyen y forman parte de la agenda de discusión pública en la sociedad contemporánea: el aborto y el control social. Es así, que se examinará desde un enfoque empírico, el porqué de la prohibición del aborto –sobre todo en aquellos países donde no se encuentra legalizada su práctica–. Con esto, se constituye la reflexión sobre un mecanismo que se encuentra orientado a implementar esquemas particulares de control social, en el cual están institucionalizados: patrones culturales, normativos y socio–políticos, que tienden a regular la reproducción, la natalidad, el libre ejercicio de la sexualidad y el derecho de las mujeres a decidir sobre su cuerpo. AbstractThis paper arises from a theoretical and conceptual perspective in which the relationship between, two approaches converge and form part of the agenda of public discussion in contemporary society is discussed: abortion and social control. Thus, it will be considered from an empirical approach, the reason for the prohibition of abortion, especially in countries where the practice is not legalized. With this, the reflection is a mechanism aimed at implementing specific schemes is social control; which are institutionalized: socio-political, which tend to regulate reproduction, birth, cultural, regulatory and free exercise patterns of sexuality and the right of women to decide about their bodies.

Amostra não probabilística controlada por seis cotas, de acordo com nível educacional e idade, refletindo a estrutura social e demográfica encontrada na PNA-urna. A maioria das mulheres entrevistadas realizou apenas um aborto, mas uma em cada quatro realizou dois abortos, e uma em cada 17 realizou três abortos. A maioria dos abortos ocorre entre jovens até 19 anos, muitas das quais já tiveram filhos. Os exames mais comuns para identificar a gravidez são o beta-HCG sérico, o teste de urina de farmácia e o ultrassom. Há uma prevalência do aborto entre mulheres negras. O principal método abortivo é uma combinação de chás e cytotec (misoprostol com a finalização em hospitais. Parentes e companheiros auxiliam em diferentes etapas do processo.

  12. El aborto en las trayectorias de mujeres y varones de la ciudad de Buenos Aires

    Mónica Petracci

    Full Text Available Sobre la base de entrevistas a treinta mujeres y treinta varones, residentes en el área metropolitana de Buenos Aires, acerca de sus experiencias de aborto, se reconstruyen trayectorias en las que el aborto constituye un hito. Se concluye que la ilegalidad no influye en la decisión de interrumpir un embarazo, sino en las condiciones diferenciales de su práctica clandestina; que las huellas del aborto marcan diferencialmente a las mujeres, en cuyo cuerpo es practicado, que a los varones, participantes secundarios del proceso, aunque las huellas sean perdurables tanto en mujeres como en varones. Asimismo, se muestra que en las mujeres pobres, al primer embarazo sigue un nacimiento y luego un aborto; que en las clases medias, al primer embarazo sigue el aborto y luego los hijos; y que la eventualidad de interrumpir el embarazo no se plantea sólo en situaciones excepcionales sino que forma parte del proceso desencadenado por la sospecha de un embarazo.

    Full Text Available No Brasil existem poucas informações sobre o aborto provocado e suas características na população. A dificuldade em se obter dados confiáveis deve-se: à sua ilegalidade, e também ao fato de que a maioria dos estudos é realizada em hospitais. Assim, em 1990, foi realizada pesquisa entre alunas da graduação e funcionárias de uma universidade brasileira. Os dados foram obtidos por meio de questionário, auto-respondido, para devolução por correio, anonimamente. Os resultados apresentados referem-se à freqüência do aborto provocado nesta população. Encontrou-se que quatro vezes menos alunas do que funcionárias tinham engravidado alguma vez (15% e 65%; 9% das alunas e 14% das funcionárias tiveram aborto provocado. Entre as mulheres que engravidaram alguma vez, as alunas tiveram mais aborto provocado do que as funcionárias (59% e 20%. Quando controladas por grupo etário as diferenças entre as alunas e funcionárias mantiveram-se. Entretanto, entre as alunas, o aborto provocado foi mais freqüente entre as mais jovens.

    Rebeca de Souza e Silva

    2012-12-01

    Full Text Available Esse artigo investiga fatores associados ao aborto induzido entre jovens residentes numa comunidade pobre da cidade de São Paulo. A amostra foi composta por 102 homens e 99 mulheres de 14 a 25 anos de idade que já haviam iniciado suas vidas sexuais. Usou-se o modelo hierárquico de regressão logística. As variáveis não ter companheiro sexual no momento da entrevista, sexo do entrevistado, idade no momento da entrevista, priorizar morar só e número de gestações compuseram o modelo final. Dar muita importância a morar só quadruplica a chance de ocorrer um aborto. Jovens mais velhos foram menos propensos a se deparar com um aborto, dado que a chance de se optar pelo aborto se reduz 17% para cada incremento de um ano na idade dos jovens. Isso é indicativo de que as gestações ocorreram de forma inesperada, intempestiva, como é praxe nas condutas adolescentes, sendo as maiores candidatas a terminarem em aborto provocado. Evidencia-se, portanto, a necessidade de serem investidos recursos financeiros para obtenção de métodos contraceptivos eficazes e inócuos, destinados ao início da vida sexual.

Este renovado sistema concede un amplio campo de autonomía a la mujer embarazada para decidir sobre su eventual maternidad durante las primeras catorce semanas de gestación, combinado con dos indicaciones por causas médicas que recogen los supuestos de peligro para la vida o salud de la mujer y las anomalías fetales. Aunque la ley está recurrida ante el Tribunal Constitucional, existen motivos suficientes para justificar su adecuación a los principios reconocidos en la Constitución española, en particular, por el declarado objetivo legal de desarrollar políticas públicas en materia de información y educación sexual y reproductiva dirigidas a reducir el alarmante número de embarazos no deseados que se registran anualmente, sobre todo entre la población juvenil. Un objetivo que puede contribuir a contener los abortos que se producen en España de modo mucho más realista y eficaz que la amenaza con sanciones penales.

    Data are presented on 240 female habitual self-mutilators. The typical subject is a 28-year-old Caucasian who first deliberately harmed herself at age 14. Skin cutting is her usual practice, but she has used other methods such as skin burning and self-hitting, and she has injured herself on at least 50 occasions. Her decision to self-mutilate is impulsive and results in temporary relief from symptoms such as racing thoughts, depersonalization, and marked anxiety. She now has or has had an eating disorder, and may be concerned about her drinking. She has been a heavy utilizer of medical and mental health services, although treatment generally has been unsatisfactory. In desperation over her inability to control her self-mutilative behavior this typical subject has attempted suicide by a drug overdose.

Objetivou-se, com ela, compreender a experiência e as necessidades de cuidado das adolescentes em situação de abortamento. Os resultados mostram que o impacto da gravidez levou-as ao medo da não aceitação da família e, ao mesmo tempo, à felicidade, pela possibilidade de ser mãe. A experiência do aborto foi marcada por sofrimento, e o atendimento foi considerado satisfatório, mas foi realçada a necessidade do recebimento de mais atenção e informação.

Os resultados indicam que, na população estudada, a indução do aborto é prática comum entre jovens, solteiras (ou que vivem sem um parceiro estável, de baixa paridade, com escolaridade incipiente e não-usuárias de métodos contraceptivos. Recomenda-se a realização de estudos que investiguem os conhecimentos relacionados a percepções, conceitos culturais do aborto, e às razões por que mulheres pobres fracassam na adoção de métodos de planejamento familiar.

  6. Experiências de abortos provocados em clínicas privadas no Nordeste brasileiro

    Paloma Silveira

    Full Text Available Resumo Baseado numa investigação qualitativa desenvolvida em 2012, o artigo analisa experiências de abortos provocados de pessoas de estratos sociais médios realizados em clínicas privadas. Foram narradas 34 histórias de gravidezes interrompidas em clínicas por 19 mulheres e cinco homens, residentes em duas capitais do Nordeste brasileiro. Uma análise temática revela que existem diferentes tipos de clínicas e de atendimento prestados pelos médicos. O artigo mostra que a realização de um aborto em uma clínica privada não é garantia de um atendimento humanizado e seguro. As narrativas fornecem descrições de diversas situações e práticas, desde aquelas com algumas falhas, como a falta de informações sobre os medicamentos, até outras com abusos graves, como procedimentos realizados sem anestesia. Assim, conclui-se que a ilegalidade da prática do aborto, no Brasil, permite que as clínicas funcionem sem qualquer tipo de regulação do Estado, não impedindo que as mulheres realizem abortos, mas as expondo a situações de total vulnerabilidade e de violação dos direitos humanos.

A amostra foi constituída por 70% da população de cada curso da área biomédica totalizando 71 respondentes. Os dados foram coletados através de questionário elaborado a partir de pesquisas exploratórias e aplicados nos locais de aula, nos meses de agosto e outubro de 1998. Os resultados estão divididos em duas partes: a primeira caracteriza a amostra e a segunda trata das questões relativas ao aborto provocado. A maior parte dos estudantes encontra-se na faixa etária de 17-22 anos, são católicos, solteiros e são dependentes financeiramente. Um percentual representativo sabe o que é aborto provocado, os métodos utilizados e suas conseqüências. São de opinião contrária ao aborto e responsabilizam o casal pela decisão de deixar ou não a gravidez evoluir, em menor percentual além da mulher, outras pessoas como amigos e familiares são apontados também como responsáveis.

    Full Text Available Resumen: Este artículo recoge algunas reflexiones teóricas ligadas a una investigación empírica en torno a los derechos sexuales y (no reproductivos, en la intersección entre los discursos sociopolíticos y las experiencias personales, con el objetivo de contribuir a comprender las dificultades para discutir pública y políticamente sobre aborto, en Argentina en particular y en Latinoamérica en general. El debate se plantea en el marco de contextos neoliberales ligados a procesos de políticas de individuación y juridificación/judicialización de los problemas sociales, incluyendo la cuestión del aborto. La hipótesis planteada apunta a subrayar las complejidades que supone la concepción de individuo vigente en el marco del neoliberalismo, a diferencia del individuo de la “sociedad organizada”, así como a resaltar las dificultades particulares que devienen del pasaje del énfasis en un discurso biomédico a otro jurídico en torno de las sexualidades. Se trata de dos problemas nodales: uno, ligado con la cuestión de lo que supone la individuación; y el otro, lo que implica la solapada persistencia del sujeto abstracto, base del sujeto de derecho, y que oblitera todas las diferencias, incluidas las económicas y sociales entre las personas (mujeres, en este caso. Asimismo se enfatiza la insistencia en la conciencia, la voluntad, la libertad, pero sobre todo, la responsabilidad que se exige al individuo neoliberal (retomando la noción de individuo liberal clásica pero actualizada a los tiempos que corren y que se traduce, en caso del aborto, en la dificultad para tolerar la “falla” que deviene de la imposibilidad de prevenir exitosamente todos los riesgos, en el marco del ejercicio de la sexualidad que se impone ahora como libre, voluntaria, consentida, responsable y placentera.

    La Corte Constitucional de Colombia, con la Sentencia C-325 de 2006, proporciona una fuente de análisis e interpretación jurídica para la despenalización del aborto en Colombia. Esa es una tarea difícil, ya que, por un lado, la población colombiana en la actualidad manifiesta una gran polarización respecto al tema, y por otro, la despenalización del aborto es objeto no solo del derecho sino también de diversas disciplinas científicas y filosóficas y de sistemas normativos como la ética, la moral y la religión. En este artículo se analiza, en primer lugar, lo que llevó a la Corte  onstitucional a pronunciarse sobre la despenalización del aborto en Colombia. En segundo lugar, se tratan las consideraciones de la Corte y el debate jurídico-ideológico que tuvo que librar para llegar a su decisión. A renglón seguido, se hace un análisis desde la bioética del debate ético-moral que ha generado tal Sentencia; y por último, se infieren algunas implicaciones de esta norma dentro del complejo funcionamiento de la sociedad colombiana.

Para ello, se hará hincapié en tres dimensiones. La primera, consiste en el análisis de los emergentes de la mencionada Carrera a la luz de las legislaciones, y regulaciones que promueven Derechos Sexuales como parte fundamental de los derechos humanos (DDHH. La segunda estriba en el análisis de tales emergentes en relación a discontinuidades y rupturas con lo que se definirá como Modelo Médico Hegemónico (MMH. Por último, se indagará en las políticas, representaciones y prácticas respecto al misoprostol. Esta investigación es de carácter cualitativo. El corpus analizado consiste en entrevistas semi-estructuradas a 24 estudiantes de la mencionada carrera y en regulaciones vigentes emitidas tanto por organismos médicos nacionales, latinoamericanos e internacionales. Como resultados preliminares, primero, se destacan la escasa permeabilidad en la carrera de las regulaciones vigentes, los conocimientos y actualizaciones farmacológicas expresadas en los documentos emitidos por organismos médicos nacionales, latinoamericanos e internacionales en los últimos 10 años. En segundo lugar, resalta la predominancia de un silencio o vacío en el currículo en relación al aborto. Este silencio no es inocuo, sino que tiene efectos concretos: no garantizar el cumplimiento con el marco de DDHH vigentes en Argentina. Por último, el desconocimiento sobre el misoprostol y su amplia utilidad en el campo gineco-obstétrico refuerza la asimetría en la relación médico/a-paciente y una idea de aborto medicalizado que, por lo tanto, robustece al MMH.

O abortamento é juridicamente permitido apenas em casos de violência sexual, risco à vida da mulher ou com comprovação de anencefalia fetal. O abortamento significa um grave problema para a saúde pública nos países em desenvolvimento, e, também no Brasil, resultando em um debate heterogêneo que é pautado por diversos aspectos legais, morais, religiosos, sociais e culturais. (Ministério da Saúde, 2011. Neste contexto nosso objetivo foi levantar informações acerca da opinião de moradores da cidade de Campos dos Goytacazes, acerca do aborto. Utilizou-se questionário fechado com escala tipo likert composto por 3 questões numa amostra de 40 pessoas escolhidas aleatoriamente. Os questionários foram aplicados em locais públicos e nas imediações do ISECENSA. A idade média dos sujeitos de pesquisa foi de 27 anos, todos maiores de 18 anos e a distribuição por gênero foi 60% gênero femininos e 40% masculino. Da amostra 55% dos sujeitos discordaram acerca da legalização do aborto e os que concordaram somaram 32,5% da amostra. Acerca da totalidade dos participantes que concordaram que haveria um aumento na procura pelo aborto, caso o mesmo fosse regulamentado somaram-se 50%, e os que discordaram acerca deste aumento somou-se 27,5%. Perguntou-se aos sujeitos de pesquisa em qual circunstância seria justificável o aborto. As respostas variaram bastante. Dentro das respostas oferecidas o resultado foi: Estupro 27,5%, Risco à vida da mãe ou do feto 27,5%, Gravidez indesejada 7,5%, Todas as respostas anteriores 25% e em nenhum dos casos 12,5%. Ressaltamos a importância de que a criminalização do abortamento seja debatida de forma ampla pela sociedade por um viés da saúde pública e da justiça social. Percebeu-se que a temática é fortemente enviesada por questões morais. Acreditamos que novas pesquisas envolvendo metodologia

Aparecen sin embargo, el riesgo de no otorgar al embrión o feto el estatuto de paciente que merece por su condición de ser personal. Existen situaciones clínicas que conllevan la alternativa de interrumpir o no un embarazo en etapas con inciertas posibilidades de sobrevida para el embrión o feto. Muchas de ellas se dan en situaciones donde es perfectamente posible mantener el embarazo, asegurando un buen desenlace para la madre y su hijo, y otras donde la gravedad de la patología arriesga tanto la vida de la madre como la de su hijo en gestación. Un médico obstetra que considera como pacientes a la madre y a su hijo comprende que la interrupción del embarazo en la primera situación constituye un aborto del llamado terapéutico y por lo tanto la muerte del feto es directamente buscada. En la segunda situación, de producirse una muerte, ésta ocurre al intentar el médico salvar a sus dos pacientes. Acción no sólo lícita sino obligatoria para el médico.

From a survey of the state of the art on this theme, in which it stood out the aperfomance of the speeches that maintain the abortion criminalization or defend that the abortion is decriminalized and legalized. Keywords : Latin America, Decriminalization of Abortion , Reproductive Rights, Feminism *** Resumen Desde la década de 1960, el feminismo de la segunda onda he destacado la cuestión de los derechos sobre el cuerpo y el libre ejercicio de la sexualidad de las mujeres. Entre los temas destacados, las feministas guían la defensa del aborto como un derecho de la mujer a ser garantizado por el Estado. A pesar del éxito logrado en gran parte de Europa, el avance de esta discusión fue reprimida en los países de América Latina, debido a la dominación de los gobiernos dictatoriales que persiguen la organización de los movimientos sociales. Desde el retorno a la democracia, el movimiento feminista de nuevo puso el tema del aborto en la agenda, sin embargo, los nuevos arreglos políticos y luchas de poder contribuyeron al aborto sigue siendo un delito penal en la mayor parte de América Latina. En este contexto, el presente estudio tuvo como objetivo analizar la situación política de América Latina con respecto a los avances y retrocesos en materia de derechos sexuales y reproductivos de las mujeres, centrándose en la despenalización del aborto a partir de un estudio del estado del arte sobre este tema que, destacando el desempeño de los discursos que actúan para mantener la penalización del aborto o que defienden que ser despenalizado y legalizado.

Tenemos que tener claridad en que nuestra oposición al aborto no es por razones religiosas ni otras particularísimas. Nos oponemos a realizar esas intervenciones porque ellas vulneran principios y valores propios de la profesión médica. Tenemos en una mujer embarazada a dos pacientes, y la medicina siempre debe respetarles la vida y otorgarles los cuidados de su salud. Debemos enseñar a nuestros alumnos a cuidar y acoger a todos nuestros pacientes como siempre lo hemos hecho.

    Full Text Available El paso relativamente rápido de la lógica del aborto terapéutico en Estados Unidos al punto de vista filosófico en el que prima la libertad de elección individual ha sido debido en gran parte al apoyo de la clase médica, muy poderosa en aquel país. El aborto pasó de ser una mera cuestión personal a ser el centro de un agrio debate sobre el que los políticos debían pronunciarse debido a que las personas que lo promovían lo hacían por razones humanitarias. Se presentan una serie de estadísticas acerca de la evolución de las actitudes de los americanos ante el aborto durante las dos últimas décadas. Se sugiere que el papel de la Iglesia Católica en la controversia se basa no sólo en su preocupación ética por la vida humana, sino en el continuado rechazo agustiniano de la relación sexual únicamente orientada hacia el placer y la subsiguiente afirmación de que sólo está legitimada de cara a la procreación.

En primer lugar realizaremos una descripción general del contexto de los casos de aborto no punible en la Argentina, resaltando que en la mayoría de los casos las creencias religiosas de los expertos suelen influir y condicionar las decisiones de las mujeres. Luego, pondremos el foco en la discusión dentro de un comité sobre un caso particular, el de una joven discapacitada que solicitó un aborto luego de un abuso sexual y que luego de atravesar un largo camino de judicialización y evaluaciones de comités de expertos, no logró interrumpir su embarazo. Este caso ilustra cómo las creencias religiosas influencian la toma de decisiones en el área de la salud pública y cómo se consolida la presencia de agentes religiosos expertos en bioética como una estrategia para influenciar los espacios públicos de la Iglesia Católica en la Argentina.

    This study investigates the influence of habitual caffeine intake on aerobic exercise-performance responses to acute caffeine supplementation. A double-blind, crossover, counterbalanced study was performed. Forty male endurance-trained cyclists were allocated into tertiles, according to their daily caffeine intake: low (58 ± 29 mg/d), moderate (143 ± 25 mg/d), and high (351 ± 139 mg/d) consumers. Participants completed three trials in which they performed simulated cycling time trials (TTs) in the fastest time possible following ingestion of the following: caffeine (CAF: 6 mg/kg body mass), placebo (PLA), and no supplement (CON). A mixed-model analysis revealed that TT performance was significantly improved in CAF compared with PLA and CON (29.92 ± 2.18 vs. 30.81 ± 2.67 and 31.14 ± 2.71 min, respectively; P = 0.0002). Analysis of covariance revealed no influence of habitual caffeine intake as a covariate on exercise performance ( P = 0.47). TT performance was not significantly different among tertiles ( P = 0.75). No correlation was observed between habitual caffeine intake and absolute changes (CAF - CON) in TT performance with caffeine ( P = 0.524). Individual analysis showed that eight, seven, and five individuals improved above the variation of the test in CAF in the low, moderate, and high tertiles, respectively. A Fisher's exact test did not show any significant differences in the number of individuals who improved in CAF among the tertiles ( P > 0.05). Blood lactate and ratings of perceived exertion were not different between trials and tertiles ( P > 0.05). Performance effects of acute caffeine supplementation during an ~30-min cycling TT performance were not influenced by the level of habitual caffeine consumption. NEW & NOTEWORTHY There has been a long-standing paradigm that habitual caffeine intake may influence the ergogenicity of caffeine supplementation.

Se plantean algunas hipótesis sobre las razones por las cuales los varones son actores secundarios en los modelos de interpretación de la reproducción y se muestra cómo ello genera lagunas conceptuales, ambivalencias prácticas y confusiones en el proceso de definición de derechos y responsabilidades en el ámbito de la reproducción, a pesar de que, a la par, los varones son identificados como actores relevantes al definir el discurso moral que pretende regular la posibilidad del aborto. Nos interesa recuperar algunos aportes del pensamiento feminista al analizar el doble código moral que se utiliza como referencia para las vivencias sexual y reproductiva de varones y de mujeres. Si bien es un texto de carácter exploratorio no nos limitamos a repetir algunos de los planteamientos del pensamiento feminista, sino que los diversificamos a partir de los llamados estudios sobre masculinidad, en términos del uso del lenguaje, del manejo del discurso y de la experiencia de los varones alrededor de dos dinamismos vinculados con la reproducción, la sexualidad y la salud.

    Full Text Available OBJECTIVE: In the last decade, important advances were made in the struggle for reproductive rights in Mexico. The goal of this study was to discover the opinions of decision-makers about the grounds for legal abortion as well as to explore their perceptions about further liberalization of abortion laws countrywide. MATERIAL AND METHODS: In-depth interviews were conducted with eight prominent decision-makers working in governmental health, law and social institutions as well as representatives of political parties. RESULTS: Six decision-makers favored a further liberalization of abortion laws. They proposed several strategies to move forward with liberalization. Two decision-makers were against abortion under all circumstances. CONCLUSIONS: Three factors seem to play a key role in the liberalization of abortion: a liberal party governing at the state level, a favorable public opinion and the pressure of NGOs promoting reproductive rights. A state-by-state approach seems more effective for generating changes in abortion laws.OBJETIVO: En la última década se realizaron avances importantes en la lucha por los derechos reproductivos en México.

    Full Text Available OBJECTIVE: If properly trained, medical students could become future opinion leaders in health policy and could help the public to understand the consequences of unwanted pregnancies and of abortions. The objective of this study was to analyze the frequency of unwanted pregnancies and induced abortions that had occurred among women who were first-year medical students at a major public university in Mexico City and to compare the experiences of those women with the experiences of the general population of Mexican females aged 15 to 24. METHODS: In 1998 we administered a cross-sectional survey to all the first-year medical students at the National Autonomous University of Mexico, which is the largest university in Latin America. For this study we analyzed 549 surveys completed by female students. RESULTS: Out of the 549 women, 120 of them (22% had been sexually active at some point. Among those 120 sexually active students, 100 of them (83% had used a contraceptive method at some time, and 19 of the 120 (16% had been pregnant. Of those 19 women who had been pregnant, 10 of them had had an illegal induced abortion (in Mexico, abortions are illegal except under a small number of extenuating circumstances. The reported abortion rate among the female medical students, 2%, was very low in comparison with the 11% rate for women of similar ages in the Mexican general population. CONCLUSIONS: The lower incidence of abortion among the female medical students indicates that when young Mexican women have access to medical information and are highly motivated to avoid unintended pregnancy and abortion, they can do so.OBJETIVO: Con entrenamiento adecuado, los estudiantes de medicina pueden convertirse en líderes de opinión con futura injerencia sobre las políticas de salud, así como ayudar al público a entender las consecuencias de los embarazos indeseados y del aborto.

Objetivo O objetivo deste trabalho foi avaliar as atitudes de estudantes de Medicina em relação à objeção de consciência ao aborto legal. Métodos Todos os estudantes das escolas médicas do Piauí foram convidados a responder a um questionário eletrônico e anônimo com perguntas sobre características sociodemográficas, objeção de consciência ao aborto e obrigações éticas em caso de recusa. Resultados A taxa de resposta foi de 66,7% (n = 1.174. Enquanto 13,2% dos estudantes apresentariam objeção de consciência por risco de morte da mulher, 31,6% objetariam quando houvesse anencefalia fetal e 50,8% em caso de estupro. Na recusa do aborto por estupro, 54% não encaminhariam a mulher a outro profissional e 72,5% não explicariam a ela as opções de tratamento. Religião foi a única característica associada à recusa para o aborto. Conclusões A objeção de consciência no aborto por estupro foi mais frequente do que nas outras circunstâncias previstas pela legislação brasileira. Os estudantes com religião estiveram mais associados à recusa.

  8. Caffeine promotes global spatial processing in habitual and non-habitual caffeine consumers

    Full Text Available Information processing is generally biased toward global cues, often at the expense of local information. Equivocal extant data suggests that arousal states may accentuate either a local or global processing bias, at least partially dependent on the nature of the manipulation, task and stimuli. To further differentiate the conditions responsible for such equivocal results we varied caffeine doses to alter physiological arousal states and measured their effect on tasks requiring the retrieval of local versus global spatial knowledge. In a double-blind, repeated-measures design, non-habitual (Exp. 1; N=36, M=42.5±29 mg/day caffeine and habitual (Exp. 2; N=34, M=579.5±311.5 mg/day caffeine caffeine consumers completed four test sessions corresponding to each of four caffeine doses (0 mg, 100 mg, 200 mg, 400 mg. During each test session, participants consumed a capsule containing one of the three doses of caffeine or placebo, waited sixty minutes, and then completed two spatial tasks, one involving memorizing maps and one spatial descriptions. A spatial statement verification task tested local versus global spatial knowledge by differentially probing memory for proximal versus distal landmark relationships. On the map learning task, results indicated that caffeine enhanced memory for distal (i.e. global compared to proximal (i.e. local comparisons at 100 (marginal, 200, and 400 mg caffeine in non-habitual consumers, and marginally beginning at 200 mg caffeine in habitual consumers. On the spatial descriptions task, caffeine enhanced memory for distal compared to proximal comparisons beginning at 100 mg in non-habitual but not habitual consumers. We thus provide evidence that caffeine-induced physiological arousal amplifies global spatial processing biases, and these effects are at least partially driven by habitual caffeine consumption.

    Society increasingly requests that individuals adopt environmentally benign behavior. Information campaigns purported to change people's attitudes are often regarded as prerequisites to installing such changes. While such information may be a necessary step, it is not sufficient by itself. We argue that many everyday behaviors with environmental consequences are habitual, and that little attention is given to information directed toward changing these habitual behaviors. In other instances, behavior is guided by values in a more reflective process. However, other information besides environmental consequences may draw a person's attention and affect behavioral choice. Using surveys and experimental studies targeting consumer behavior, we studied under what conditions different kinds of information is likely to influence people with varying levels of environmental concern. Based on results from these studies, implications for behavioral change are discussed.

  11. Habituation and sensitization in primary headaches

    Science.gov (United States)

    2013-01-01

    The phenomena of habituation and sensitization are considered most useful for studying the neuronal substrates of information processing in the CNS. Both were studied in primary headaches, that are functional disorders of the brain characterized by an abnormal responsivity to any kind of incoming innocuous or painful stimuli and it’s cycling pattern over time (interictal, pre-ictal, ictal). The present review summarizes available data on stimulus responsivity in primary headaches obtained with clinical neurophysiology. In migraine, the majority of electrophysiological studies between attacks have shown that, for a number of different sensory modalities, the brain is characterised by a lack of habituation of evoked responses to repeated stimuli. This abnormal processing of the incoming information reaches its maximum a few days before the beginning of an attack, and normalizes during the attack, at a time when sensitization may also manifest itself. An abnormal rhythmic activity between thalamus and cortex, namely thalamocortical dysrhythmia, may be the pathophysiological mechanism subtending abnormal information processing in migraine. In tension-type headache (TTH), only few signs of deficient habituation were observed only in subgroups of patients. By contrast, using grand-average responses indirect evidence for sensitization has been found in chronic TTH with increased nociceptive specific reflexes and evoked potentials. Generalized increased sensitivity to pain (lower thresholds and increased pain rating) and a dysfunction in supraspinal descending pain control systems may contribute to the development and/or maintenance of central sensitization in chronic TTH. Cluster headache patients are chrarcterized during the bout and on the headache side by a pronounced lack of habituation of the brainstem blink reflex and a general sensitization of pain processing.

    This study analyzed the relationship of individual differences in personality with habituation in the acoustic startle response (ASR). Data from nine trials in ASR to white noise bursts and a personality questionnaire based on the alternative big five personality approach were modelled with a latent growth curve (LCM) including intercept and slope habituation growth factors. There was a negative correlation between the intercept and slope, indicating that individuals with higher initial ASR levels had also a more pronounced and faster decrease in the ASR. Contrary to expectations, Extraversion and Sensation Seeking did not relate with habituation in ASR. Neuroticism and Aggressiveness related asymmetrically with the habituation rate in ASR. Higher levels of Neuroticism were related with faster habituation, whereas higher levels of Aggressiveness were related with slower habituation. Further studies with the LCM should be undertaken to clarify in a greater extent the association of personality with habituation in ASR. Copyright © 2014 Elsevier B.V. All rights reserved.

    Full Text Available Os debates e as ações feministas em prol da liberalização do aborto no Brasil foram marcados por avanços, recuos e, sobretudo, por inúmeras negociações políticas. Da omissão da palavra "aborto", em meados dos anos 70, à opção política pela descriminalização e pela realização dos casos previstos por lei, observa-se uma vocação política do feminismo brasileiro para a negociação. Conclui-se que essas negociações tiveram mais êxito em nível político do que social, pois não lograram alcançar e sensibilizar camadas mais amplas da população.The debates and feminist actions in favor of the legalization of abortion in Brazil were characterized by progresses and regressions, and above all by countless political negotiations. From the omission of the word "abortion", in the mid-seventies, to the political choice of decriminalization and application of the cases foreseen by law, Brazilian feminism has been marked by the choice of negotiation. The article concludes that these negotiations have succeeded politically but failed to reach society and heighten public awareness at a large scale.

    2013-01-01

    Background Temporomandibular disorders are the most common cause of chronic orofacial pain, but, except where they occur subsequent to trauma, their cause remains unknown. This cross-sectional study assessed chewing function (habitual chewing side) and the differences of the chewing side and condylar path and lateral anterior guidance angles in participants with chronic unilateral temporomandibular disorder. This is the preliminary report of a randomized trial that aimed to test the effect of a new occlusal adjustment therapy. Methods The masticatory function of 21 randomly selected completely dentate participants with chronic temporomandibular disorders (all but one with unilateral symptoms) was assessed by observing them eat almonds, inspecting the lateral horizontal movement of the jaw, with kinesiography, and by means of interview. The condylar path in the sagittal plane and the lateral anterior guidance angles with respect to the Frankfort horizontal plane in the frontal plane were measured on both sides in each individual. Results Sixteen of 20 participants with unilateral symptoms chewed on the affected side; the concordance (Fisher’s exact test, P = .003) and the concordance-symmetry level (Kappa coefficient κ = 0.689; 95% confidence interval [CI], 0.38 to 0.99; P = .002) were significant. The mean condylar path angle was steeper (53.47(10.88) degrees versus 46.16(7.25) degrees; P = .001), and the mean lateral anterior guidance angle was flatter (41.63(13.35) degrees versus 48.32(9.53) degrees P = .036) on the symptomatic side. Discussion The results of this study support the use of a new term based on etiology, “habitual chewing side syndrome”, instead of the nonspecific symptom-based “temporomandibular joint disorders”; this denomination is characterized in adults by a steeper condylar path, flatter lateral anterior guidance, and habitual chewing on the symptomatic side.

    2016-01-01

    Full Text Available The habituation/cross-habituation test (HaXha is a spontaneous odor discrimination task that has been used for many decades to evaluate olfactory function in animals. Animals are presented repeatedly with the same odorant after which a new odorant is introduced. The time the animal explores the odor object is measured. An animal is considered to cross-habituate during the novel stimulus trial when the exploration time is higher than the prior trial and indicates the degree of olfactory patency. On the other hand, habituation across the repeated trials involves decreased exploration time and is related to memory patency, especially at long intervals. Classically exploration is timed using a stopwatch when the animal is within 2 cm of the object and aimed toward it. These criteria are intuitive, but it is unclear how they relate to olfactory exploration, that is, sniffing. We used video tracking combined with plethysmography to improve accuracy, avoid observer bias, and propose more robust criteria for exploratory scoring when sniff measures are not available. We also demonstrate that sniff rate combined with proximity is the most direct measure of odorant exploration and provide a robust and sensitive criterion.

    2012-08-01

    Our paper explores the interaction of persistent firing axonal and presynaptic processes in the generation of short term memory for habituation. We first propose a model of a sensory neuron whose axon is able to switch between passive conduction and persistent firing states, thereby triggering short term retention to the stimulus. Then we propose a model of a habituating synapse and explore all nine of the behavioral characteristics of short term habituation in a two neuron circuit. We couple the persistent firing neuron to the habituation synapse and investigate the behavior of short term retention of habituating response. Simulations show that, depending on the amount of synaptic resources, persistent firing either results in continued habituation or maintains the response, both leading to longer recovery times. The effectiveness of the model as an element in a bio-inspired memory system is discussed.

    La historia de Vera Drake nos recuerda no sólo los tiempos pasados sino también los nuestros, porque, como entonces, las mujeres todavía no controlan su cuerpo; pueden abortar, pero tienen que mentir sobre el por qué; pueden abortar, pero eso no forma parte de su derecho a la salud y a la sanidad básicas. Detrás de ello lo que asoma es una cierta construcción ideológica del aborto que aún mantiene parte de la fuerza que tuvo antaño, y que, por eso, la bioética debe seguir revisando y cuest...

    Full Text Available Lithuanian has regular past habitual forms with the suffix -dav-, which can be explained as an originally iterative suffix -dau- restricted to the past tense (Fraenkel 1936. Dialectal and Old Lithuanian, in addition to -dav-, also feature habituals with the suffixes -lav- and -dlav-, which could have followed the same path of development (Fraenkel 1936, as evidenced by a number of diverse languages (Bybee et al. 1994. Using an electronic edition of Lietuvių kalbos žodynas (The Dictionary of Lithuanian as the data source, a limited number of possible iteratives with -dau- and other related suffixes were found, which has led to two main conclusions. (1 Habituals were restricted to the past tense before the appearance of the first written Lithuanian texts (mid-16th c. and the present and the infinitive stems went out of use. If this had not been the case, more corresponding verbal formations should have remained. (2 Iteratives with the habitual-to-be suffixes had to be productive to some extent in the dialects, which grammaticalized them as past habituals. If these formations had been productive in all dialects of Lithuanian, more iteratives should have been found in the areas that did not grammaticalize them as past habituals. It is also suggested that the form-frequency correspondence principle (Haspelmath 2008, 2014, 2017 should have operated in the formation of the Lithuanian habitual. Longer suffixes were chosen to mark habitual situations as a less frequent subtype of iterative situations and habitual forms were restricted to the past tense because habituality is one of the default (more frequent readings of the present and hence the habituals in the past tend to be marked explicitly (Bybee et al. 1994.

    Full Text Available OBJECTIVE: We aim to assess the opinions of Mexicans in the state of Tlaxcala on abortion and other topics concerning women's reproductive health and status in society. MATERIAL AND METHODS: We summarize opinions on abortion and women's roles in society and perform logit regressions to assess characteristics correlated with support for abortion rights. RESULTS: A majority of respondents were against a woman's right to abortion when asked generally, but when asked about specific circumstances, a majority supported the right to abortion in five of the nine hypothetical circumstances proposed. In multivariate analysis, age, education, religion, religious service attendance, and views regarding women's roles in society had significant effects on support for the right to abortion. CONCLUSIONS: Our results demonstrate that residents of Tlaxcala view abortion as a personal decision and support a woman's right to abortion in more circumstances than currently allowed under state law.OBJETIVO: Describir opiniones sobre salud sexual y reproductiva, aborto y rol social de las mujeres entre un grupo de residentes de Tlaxcala, México.

    Full Text Available Mitochondrial disease is the most common neuromuscular disease and has a profound impact upon daily life, disease and longevity. Exercise therapy has been shown to improve mitochondrial function in patients with mitochondrial disease. However, no information exists about the level of habitual physical activity of people with mitochondrial disease and its relationship with clinical phenotype.Habitual physical activity, genotype and clinical presentations were assessed in 100 patients with mitochondrial disease. Comparisons were made with a control group individually matched by age, gender and BMI.Patients with mitochondrial disease had significantly lower levels of physical activity in comparison to matched people without mitochondrial disease (steps/day; 6883±3944 vs. 9924±4088, p = 0.001. 78% of the mitochondrial disease cohort did not achieve 10,000 steps per day and 48% were classified as overweight or obese. Mitochondrial disease was associated with less breaks in sedentary activity (Sedentary to Active Transitions, % per day; 13±0.03 vs. 14±0.03, p = 0.001 and an increase in sedentary bout duration (bout lengths/fraction of total sedentary time; 0.206±0.044 vs. 0.187±0.026, p = 0.001. After adjusting for covariates, higher physical activity was moderately associated with lower clinical disease burden (steps/day; r(s = -0.49; 95% CI -0.33, -0.63, P<0.01. There were no systematic differences in physical activity between different genotypes mitochondrial disease.These results demonstrate for the first time that low levels of physical activity are prominent in mitochondrial disease. Combined with a high prevalence of obesity, physical activity may constitute a significant and potentially modifiable risk factor in mitochondrial disease.

    The ability of horses to habituate to frightening stimuli greatly increases safety in the horse–human relationship. A recent experiment suggested, however, that habituation to frightening visual stimuli is relatively stimulus-specific in horses and that shape and colour are important factors...... for object generalisation (Christensen et al., 2008). In a series of experiments, we aimed to further explore the ability of horses (n = 30, 1 and 2-year-old mares) to recognise and generalise between objects during habituation. TEST horses (n = 15) were habituated to a complex object, composed of five...... simple objects of varying shape and colour, whereas CONTROL horses (n = 15) were habituated to the test arena, but not to the complex object. In the first experiment, we investigated whether TEST horses subsequently reacted less to i) simple objects that were previously part of the complex object (i...

    Full Text Available Resumen Augusta García Platas murió tras un aborto clandestino en Ayacucho en 1946. Este ensayo, basado en materiales del Archivo Histórico de Ayacucho, da cuenta del proceso criminal que se abrió para determinar los responsables de su muerte. A pesar de que sindicaron a ciertos individuos como culpables directos de provocar el aborto, las autoridades judiciales consideraban que la causa de fondo de la muerte de la joven había sido el abandono por parte de quienes debían velar por su salud física y moral. Este caso nos brinda la oportunidad de esclarecer las estrategias que los implicados usaban para defenderse de acusaciones criminales. Además, nos ayuda a entender las diversas deficiencias del Poder Judicial peruano de mediados del siglo XX.

    Full Text Available Qualquer tentativa de se investigar a prática de abortos ilegais deve lidar com o problema de estar perguntando às mulheres acerca de um tema delicado, sensível, com implicações múltiplas, o que leva a dificuldades para se obter informações verazes. O estudo realizado enfoca principalmente aspectos metodológicos de uma pesquisa realizada junto a uma população de mulheres de 15 a 49 anos de idade, com o objetivo de verificar a freqüência e as condições em que era feito o aborto provocado em uma região do Estado de São Paulo (Brasil. Foram entrevistadas, em seus domicílios, 1.955 mulheres. Utilizou-se um questionário estruturado e pré-testado. A maioria das entrevistadas declarou nunca ter abortado nem pensado em fazê-lo, enquanto 4% referiram alguma vez ter feito aborto; 16,7% disseram que, pelo menos uma vez, tomaram chá/remédio para menstruar. Entre as que acreditaram estar grávidas na ocasião, a maioria informou nunca ter abortado, apesar de terem menstruado quando ingeriram chá/remédio. Os resultados permitiram concluir que as mulheres tendem a omitir a informação sobre a prática de aborto quando perguntadas diretamente sobre isso. Especialmente aquelas que o induzem por ingestão de substâncias parecem não reconhecer esse ato como sendo uma forma de interromper a gestação.

    Full Text Available O artigo analisa representações do aborto por meio do discurso e imagens contidas em documentários. Na controvérsia do aborto no espaço público, grupos alinhados pró-vida e pró-escolha buscam o audiovisual como meio de propagar suas mensagens políticas. A retórica visual pró-vida recorre a imagens de diferentes estágios do desenvolvimento para provar a individualidade de embriões e fetos e sua condição de pessoa dotada de direitos. O movimento pró-escolha constrói seu discurso por meio de relatos de pessoas que passaram pela experiência do aborto, enfatizando o sofrimento e a violência da criminalização e da clandestinidade. O foco é a mulher como sujeito moral. A exceção está no tópico da anencefalia, quando imagens são usadas para representar a figura do "bebê sem cérebro" inviável. A partir do sofrimento e da violência, fetos e mulheres são apresentados como vítimas pelos diferentes lados da disputa, modo de reivindicar acesso a direitos.

  19. Differences in the locomotor-activating effects of indirect serotonin agonists in habituated and non-habituated rats.

    2012-07-01

    The indirect serotonin (5-HT) agonist 3,4-methylenedioxymethamphetamine (MDMA) produces a distinct behavioral profile in rats consisting of locomotor hyperactivity, thigmotaxis, and decreased exploration. The indirect 5-HT agonist α-ethyltryptamine (AET) produces a similar behavioral profile. Using the Behavioral Pattern Monitor (BPM), the present investigation examined whether the effects of MDMA and AET are dependent on the novelty of the testing environment. These experiments were conducted in Sprague-Dawley rats housed on a reversed light cycle and tested during the dark phase of the light/dark cycle. We found that racemic MDMA (RS-MDMA; 3 mg/kg, SC) increased locomotor activity in rats tested in novel BPM chambers, but had no effect on locomotor activity in rats habituated to the BPM chambers immediately prior to testing. Likewise, AET (5 mg/kg, SC) increased locomotor activity in non-habituated animals but not in animals habituated to the test chambers. These results were unexpected because previous reports indicate that MDMA has robust locomotor-activating effects in habituated animals. To further examine the influence of habituation on MDMA-induced locomotor activity, we conducted parametric studies with S-(+)-MDMA (the more active enantiomer) in habituated and non-habituated rats housed on a standard or reversed light cycle. Light cycle was included as a variable due to reported differences in sensitivity to serotonergic ligands during the dark and light phases. In confirmation of our initial studies, rats tested during the dark phase and habituated to the BPM did not show an S-(+)-MDMA (3 mg/kg, SC)-induced increase in locomotor activity, whereas non-habituated rats did. By contrast, in rats tested during the light phase, S-(+)-MDMA increased locomotor activity in both non-habituated and habituated rats, although the response in habituated animals was attenuated.

    To describe foveal damage in habitual use of poppers, a popular recreational drug. Retrospective observational case series. Six patients with bilateral vision loss after chronic popper inhalation were seen in 4 university-based ophthalmology departments. Symptoms, medical history, ophthalmic examination, and functional and morphological tests are described. All patients experienced progressive bilateral vision loss, with central photopsia in 2 cases. Initial visual acuities ranged from 20/50 to 20/25. In all patients, a bilateral yellow foveal spot was present that, by optical coherence tomography, was associated with disruption of the outer segments of foveal cones. Functional and anatomical damage was restricted to the fovea. The poppers involved were identified as isopropyl nitrite in 3 cases. Four patients showed anatomical and/or functional improvement over several months after discontinuing popper inhalation. Repeated inhalation of poppers may be associated with prolonged bilateral vision loss due to the disruption of foveal cone outer segments. Retinal damage may progressively improve following drug discontinuation.

    Full Text Available Estudo quantitativo, com o objetivo de estudar a violência doméstica em mulheres em situação de aborto provocado. Foram entrevistas 147 mulheres internadas por aborto provocado numa maternidade pública, na cidade de Salvador-BA. Os sujeitos foram, na maioria, mulheres jovens, negras, com baixa escolaridade, dependentes economicamente dos cônjuges, que vivenciam violência psicológica, física e sexual cometida pelos cônjuges. Quase metade das mulheres vivenciou violência doméstica durante a gravidez atual, sendo este o motivo do aborto para 67% delas. Conclui-se que existe uma associação entre a vivência de violência doméstica e o aborto provocado. Isso repercute na saúde mental das mulheres, que desenvolvem sintomas do transtorno de estresse pós-traumático. Necessita-se, portanto, de um olhar por parte dos profissionais de saúde de modo a identificar a violência doméstica enquanto agravo e associá-la ao aborto provocado, o que requer transformação no modelo de formação, incorporando a violência doméstica como objeto da saúde.

    Full Text Available La ley de "matrimonio igualitario", votada en 2010 por el parlamento argentino, convirtió a este país en el primero de Latinoamérica en legalizar el matrimonio homosexual. Se trata de una victoria para un grupo históricamente discriminado por sus preferencias eróticas y hasta entonces ausente de la legislación. En este contexto, aparentemente auspicioso para la igualdad sexual, considero, sin embargo, que la nueva ley no se corresponde con el orden sexual que regula los cuerpos de las mujeres argentinas. En efecto, desde 1921 el Código Penal argentino tipifica al aborto como un "delito contra la vida" y, pese a ello, cada año unas cien mujeres mueren por abortos clandestinos. En base a esta situación, en este artículo analizaré el desfasaje que encuentro entre las políticas homosexuales y las políticas reproductivas de Argentina. A diferencia de Europa, donde los derechos reproductivos precedieron a las políticas homosexuales, en este país se ha operado lo inverso. Allí, el reconocimiento legal de las parejas de mismo sexo coincide con las medidas impulsadas por otras democracias, tendientes a alcanzar lo que algunos autores denominan ciudadanía sexual. Sin embargo, mientras la Argentina no reconozca el derecho a la interrupción gratuita y segura del embarazo, esta noción, que legitima la aplicabilidad universal de derechos sexuales, seguirá siendo problemática. Considero que sin el derecho a la libre disposición del propio cuerpo, el cual comprende la libertad sexual y el derecho a decidir sobre la gestación, en el actual contexto argentino la ley de matrimonio gay representa un episodio aislado.The Argentine Parliament recently passed the New Equal Marriage Act for same-sex couples, making Argentina the first country in Latin America to legalize this type of union. This act represents a victory for a group historically discriminated for its sexual preferences and until then absent from the national legislation. In this

    Bee, M A

    2001-09-01

    The aggressive response of male bullfrogs (Rana catesbeiana) habituates with repeated broadcasts of acoustic stimuli simulating a new territorial neighbor. The effects of stimulus repetition rate and stimulus intensity on bullfrog aggressive responses were tested in a field experiment designed to test the assumptions of a dual-process theory of habituation. Synthetic advertisement calls were broadcast at 2 repetition rates and 2 intensities in a factorial design. Bullfrogs were more aggressive at the higher stimulus intensity at both repetition rates. Aggressive responses habituated more slowly at the higher stimulus intensity and slower repetition rate compared with other treatments. Several biotic and abiotic factors had small or negligible effects on aggressive responses. Although consistent with the operation of 2 opposing processes, habituation and sensitization, the data provide only partial support for the assumptions of dual-process theory.

  10. LA DISTANCIA ENTRE EL DISCURSO JURÍDICO Y LA PRÁCTICA DEL ABORTO EN COLOMBIA

    Full Text Available La concepción originaria de la Corte Constitucional, respecto de si el nasciturus es poseedor o no del derecho absoluto a la vida, ha ido cambiando gradualmente a medida que han ido pasando las sentencias que han estudiado el tema. No se ha llegado a la idea de considerar que el derecho a la vida se posee, al igual que todos los derechos fundamentales, desde el nacimiento, sin embargo, sí ha ido calando en la Corte la idea que el derecho a la vida del nasciturus, si es que este lo posee, no es absoluto y por eso en ocasiones debe ceder frente a los derechos de la mujer. 'El derecho al aborto y La tolerancia en el discurso iusfilosófico y la vigencia del pensamiento liberal en América Latina' son trabajos de investigación en donde se hace manifiesto el uso del término tolerancia en los diferentes sectores de poder de la sociedad y como argumento de aceptación a la diferencia, por lo tanto, para un país como Colombia, es particularmente problemático que el aborto admita una tolerancia en sentido positivo, esto porque la influencia del discurso religioso es tan fuerte que coarta las decisiones públicas aun en desmedro de las políticas de salud. Por esto se hace necesario elaborar un discurso conciliador entre el estamento político y los pronunciamientos dogmáticos de la iglesia católica en Colombia en lo que al aborto se refiere.

    Full Text Available Serão analisados neste ensaio alguns dos debates em torno da temática do aborto que ocorreram no Congresso Nacional com a ocasião da Proposta de Emenda Constitucional - central da discussão foi a defesa da vida. Serão identificados os blocos discursivos que apresentam posições contrárias e favoráveis à interrupção da gravidez, os princípios religiosos ou determinismo biológico em que essas posições estão ancoradas e as formas como esses discursos permanecem. Ainda são levantadas as diferentes compreensões do que é vida, decorrentes dos argumentos utilizados nesses discursos, os quais estão alinhados com os posicionamentos da Igreja Católica e do Movimento Feminista, atores sociais protagonistas desse embate.This essay will analyze some of the debates around abortion in the National Congress due to the Constitutional Amendment Bill - PEC25/95, by Deputy Severino Cavalcanti (PPB/PE, where the main issue was precisely life defense. The discursive blocks that present the debate in relation to pregnancy interruption, the religious principles or biological determinism on which those debates are based, and the ways in which such discourses are maintained will be identified. Distinct understandings of life, as a result of the points used in such discourses, which are aligned with the position of the Catholic Church and the Feminist Movement - the social actors of this debate- are also discussed here.

    Full Text Available Objetivo: Comprender la percepción acerca de la interrupción voluntaria del embarazo (ive, bajo las tres causales definidas en la Sentencia C-355 del 2006, en un grupo de médicos del Hospital de San José, Bogotá-Colombia. Metodología: Estudio cualitativo hermenéutico. La muestra se configuró con quince médicos del servicio de Ginecología y Obstetricia seleccionados por muestreo teórico y el tamaño de la muestra se determinó por saturación de la información. Los datos se obtuvieron mediante entrevistas a profundidad que fueron analizadas con la propuesta de Heidegger, Diekelman, Allen y Tanner. Resultados: La Sentencia C-355 de 2006, fue percibida como una disposición necesaria que le reconoce a la mujer el derecho a decidir sobre su vida y reproducción; además, ofrece una interrupción del embarazo segura. Asimismo, aporta a la disminución de problemáticas sociales, del sistema de salud y familiares; aunque en la sociedad colombiana persiste una percepción negativa de la ive. No obstante, señalaron las falencias de la Sentencia: ausencia en las definiciones del concepto de salud y del límite de semanas de gestación para acceder a la ive; y de atención psicológica y genética posterior a la interrupción. Discusión: La Sentencia es un avance significativo para Colombia. A pesar de aceptar la ive, los participantes reconocen los cuestionamientos que nacen de esta práctica y que son producto de sus valores religiosos y familiares, y de la estigmatización social del aborto. Conclusiones: Es inminente la revisión de la Sentencia y la participación de los médicos en este proceso

    Full Text Available Pistillate flower abscission (PFA severely affects walnut (Juglans regia L. production, mainly of the cultivar ‘Serr’. A study on symptoms of flower abortion in walnut ‘Serr’, induced by excess or lack of pollen, was carried out following the evolution of flowers and peduncles. Hand pollinated flowers, with different pollen concentrations: 0, 1, 5, 25, 50 and 100% pollen diluted (w/w in talcum powder, showed external and internal abortion symptoms. External symptoms were recorded directly from the tree, while for internal symptoms, flower excisions stained with blue Toluidin-O at 0.05%, were analyzed under an optical microscope. Excess pollen abortion produced flowers with rapid damage. The growth rate was very low, involucre brightness was lost and the stigma turned necrotic, in contrast to the flower aborted from lack of pollen. Normal flowers continued growing to fruit harvest, without losing brightness. Excess pollen abortion induced flower drop, with or without attached peduncle. Two separation zones can be present: the distal and proximal areas of the peduncle. Peduncle scars allowed for differentiating abortion induced from excess or lack of pollen, or other reasons.El aborto en flores postiladas (PFA por exceso de polen que afecta al nogal (Juglans regia L., disminuye considerablemente la producción de nueces, principalmente en el cultivar ‘Serr’. Se estudió la sintomatología del aborto por exceso y falta de polinización en flores y pedúnculo de este cultivar. Para esto se realizó polinización manual, utilizando diferentes concentraciones de polen sobre flores en diferentes estados de receptividad. Las concentraciones se obtuvieron mediante diluciones (peso/peso de polen combinado con talco. Las concentraciones utilizadas fueron 0; 1; 5; 25; 50 y 100% de polen. Se observó la sintomatología externa e interna de la flor, mediante apreciación visual en el árbol y a través de cortes longitudinales en la flor para

    To test for relationships between objectively measured habitual physical activity and fundamental movement skills in a relatively large and representative sample of preschool children. Physical activity was measured over 6 d using the Computer Science and Applications (CSA) accelerometer in 394 boys and girls (mean age 4.2, SD 0.5 yr). Children were scored on 15 fundamental movement skills, based on the Movement Assessment Battery, by a single observer. Total physical activity (r=0.10, Pmovement skills score. Time spent in light-intensity physical activity was not significantly correlated with motor skills score (r=0.02, P>0.05). In this sample and setting, fundamental movement skills were significantly associated with habitual physical activity, but the association between the two variables was weak. The present study questions whether the widely assumed relationships between motor skills and habitual physical activity actually exist in young children.

    Full Text Available O estudo objetivou descrever a relação entre aborto e saúde pública no Brasil, sob a perspectiva dos direitos humanos. Trata-se de uma revisão de literatura realizada na base de dados SciELO. Verificou-se que a busca de mulheres pelos seus direitos perdura por décadas e, mesmo alcançando várias conquistas, como as ocorridas na assistência à saúde da mulher, ainda são necessárias outras mudanças, como, por exemplo, na assistência preventiva da gravidez indesejada e no respeito aos direitos humanos de mulheres que desejam abortar. Conclui-se que, por conta da criminalização do aborto no País, diversas mulheres realizam este procedimento de forma insegura, provocando danos a sua própria saúde, o que se configura em uma violação dos direitos humanos.

  2. Physiological, Molecular and Genetic Mechanisms of Long-Term Habituation

    2009-09-12

    Work funded on this grant has explored the mechanisms of long-term habituation, a ubiquitous form of learning that plays a key role in basic cognitive functioning. Specifically, behavioral, physiological, and molecular mechanisms of habituation have been explored using a simple model system, the tail-elicited siphon-withdrawal reflex (T-SWR) in the marine mollusk Aplysia californica. Substantial progress has been made on the first and third aims, providing some fundamental insights into the mechanisms by which memories are stored. We have characterized the physiological correlates of short- and long-term habituation. We found that short-term habituation is accompanied by a robust sensory adaptation, whereas long-term habituation is accompanied by alterations in sensory and interneuron synaptic efficacy. Thus, our data indicates memories can be shifted between different sites in a neural network as they are consolidated from short to long term. At the molecular level, we have accomplished microarray analysis comparing gene expression in both habituated and control ganglia. We have identified a network of putatively regulated transcripts that seems particularly targeted towards synaptic changes (e.g. SNAP25, calmodulin) . We are now beginning additional work to confirm regulation of these transcripts and build a more detailed understanding of the cascade of molecular events leading to the permanent storage of long-term memories. On the third aim, we have fostered a nascent neuroscience program via a variety of successful initiatives. We have funded over 11 undergraduate neuroscience scholars, several of whom have been recognized at national and regional levels for their research. We have also conducted a pioneering summer research program for community college students which is helping enhance access of underrepresented groups to life science careers. Despite minimal progress on the second aim, this project has provided a) novel insight into the network mechanisms by

El análisis de diversas situaciones – algunas límite (como el caso del aborto – nos permiten problematizar qué se entiende por “sujetos/personas autónomos/as” en el ámbito de la salud-enfermedad. Aquí exponemos los resultados del análisis que, por un lado problematizan la noción de autonomía desligándola de la matrizliberal y poniéndola en relación con el cuerpo y las emociones en el marco de relaciones interpersonales; y por otro, permiten operacionalizar la tipología de paciente definido en función de la autonomía de la que partimos (sujeto pasivo, consumidor/usuario, e interlocutor-ciudadano.

    Coffee drinking is the main source of caffeine intake among adult population in the western world. It has been reported that low to moderate caffeine intake has beneficial effect on alertness and cognitive functions in healthy subjects. The aim of this study is to evaluate the impact of habitual coffee consumption on cognitive function in hemodialysis patients. In a cross-sectional study, 86 patients from a single-dialysis centre underwent assessment by the Montreal Cognitive Assessment tool and evaluation for symptoms of fatigue, mood, and sleep disorders by well-validated questionnaires. The habitual coffee use and the average daily caffeine intake were estimated by participants' response to a dietary questionnaire. Sixty-seven subjects (78%) consumed black coffee daily, mostly in low to moderate dose. Cognitive impairment was found in three-quarters of tested patients. Normal mental performance was more often in habitual coffee users (25% versus 16%). Regular coffee drinkers achieved higher mean scores on all tested cognitive domains, but a significant positive correlation was found only for items that measure attention and concentration (P = 0.024). Moderate caffeine intake by habitual coffee consumption could have beneficial impact on cognitive function in hemodialysis patients due to selective enhancement of attention and vigilance.

    Habituation to sex pheromones is one of the key mechanisms in mating disruption, an insect control tactic. Male moths often show reduced sexual response after pre-exposure to female sex pheromone. Mating disruption is relatively rare in insect orders other than Lepidoptera. As a positive control we confirmed habituation in a moth (Epiphyas postvittana) using 24 h pre-exposure to sex pheromone to reduce subsequent activation behaviour. We then tested the impact of pre-exposure to sex or trail pheromone on subsequent behavioural response with insects from three other orders. Similar pre-exposure for 24 h to either sex pheromone [Pseudococcus calceolariae (Homoptera) and apple leaf curling midge Dasineura mali (Diptera), or trail pheromone of Argentine ants (Linepithema humile (Hymenoptera)], followed by behavioural assay in clean air provided no evidence of habituation after pre-exposure in these latter cases. The moths alone were affected by pre-exposure to pheromone. For pests without habituation, sustained attraction to a point source may make lure and kill more economical. Improved knowledge of behavioural processes should lead to better success in pest management and mechanisms should be investigated further to inform studies and practical efforts generally enhancing effectiveness of pheromone-based management. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

    Full Text Available Embora o aborto provocado no Brasil seja importante problema de saúde, é difícil conhecer a exata medida de sua ocorrência, em função da ilegalidade dessa prática. Com a disponibilidade das informações sobre as hospitalizações pelo Ministério da Saúde, tornou-se possível conhecer, ainda que de forma incompleta, o quadro dos abortos atendidos na rede hospitalar do SUS. O objetivo do estudo foi conhecer as 53.861 internações com diagnóstico de aborto entre mulheres de 10 a 49 anos na rede hospitalar conveniada com o SUS no Estado de São Paulo no ano de 1995, segundo o tipo do aborto, idade e local de residência. As internações de mulheres em idade reprodutiva no Estado de São Paulo, em 1995, representaram 37,8% do total das hospitalizações pagas pelo SUS, sendo que dessas 59,6% foram por questões ligadas à gravidez, parto e puerpério, dentre as quais os abortos representam cerca de 10%. Sua distribuição nas regiões da Grande São Paulo e Interior do Estado mostra que é maior a proporção aborto/parto entre as mulheres da Grande São Paulo do que do Interior (127,4 abortos a cada 1.000 partos na Grande São Paulo contra 90,9 no Interior. O tipo de aborto mais freqüente foi o aborto espontâneo (57,4% e a distribuição por idade mostra uma concentração entre os 20 e 29 anos, além de revelar que cerca de 20% deles ocorreram em adolescentes com menos de 19 anos.Despite the importance of the issue of abortion in Brazil, it is difficult to know the exact extent of the problem owing to the fact that it is an illegal practice.

The objective of the study was to investigate the 53,861 hospitalizations diagnosed as abortion among women from 10 to 49 years of age in hospitals affiliated to SUS in the state

    Full Text Available La presente investigación ex post facto analiza la relación entre la duración habitual de sueño y el estado de ánimo deprimido. La muestra estuvo compuesta por 141 estudiantes sanos de ambos sexos, 19 con patrón de sueño corto (6 horas de sueño diario o menos, 64 con patrón de sueño intermedio (7-8 horas de sueño diario y 58 con patrón de sueño largo (más de 9 horas de sueño diario. El ánimo deprimido se evaluó con el Inventario de Depresión de Beck (BDI y la subescala de depresión del Cuestionario de Salud General (GHQ-28. Los sujetos con patrón de sueño corto y largo mostraban puntuaciones superiores en ánimo deprimido que aquellos con patrón de sueño intermedio. El análisis de cada uno de los ítems de depresión específicos mostró que los sujetos con patrón de sueño corto diferían de los patrones de sueño intermedio en los síntomas somáticos de la depresión, mientras las diferencias entre los sujetos con patrón de sueño largo e intermedio se producían en aspectos cognitivos. Se presentan algunas hipótesis explicativas sobre los mecanismos que pueden estar mediando las relaciones entre duración de sueño y estado de ánimo deprimido. El desarrollo de iniciativas educacionales destinadas a optimizar los hábitos de sueño de los estudiantes puede ser útil para prevenir depresiones futuras.

    To evaluate and compare the temporal changes in pulse waveform parameters of ocular blood flow (OBF) between non-habitual and habitual groups due to caffeine intake. This study was conducted on 19 healthy subjects (non-habitual 8; habitual 11), non-smoking and between 21 and 30 years of age. Using laser speckle flowgraphy (LSFG), three areas of optical nerve head were analyzed which are vessel, tissue, and overall, each with ten pulse waveform parameters, namely mean blur rate (MBR), fluctuation, skew, blowout score (BOS), blowout time (BOT), rising rate, falling rate, flow acceleration index (FAI), acceleration time index (ATI), and resistive index (RI). Two-way mixed ANOVA was used to determine the difference between every two groups where p groups in several ocular pulse waveform parameters, namely MBR (overall, vessel, tissue), BOT (overall), rising rate (overall), and falling rate (vessel), all with p group, but not within the habitual group. The temporal changes in parameters MBR (vessel, tissue), skew (overall, vessel), BOT (overall, vessel), rising rate (overall), falling rate (overall, vessel), and FAI (tissue) were significant for both groups (habitual and non-habitual) in response to caffeine intake. The experiment results demonstrated caffeine does modulate OBF significantly and response differently in non-habitual and habitual groups. Among all ten parameters, MBR and BOT were identified as the suitable biomarkers to differentiate between the two groups.

    Because of the recent improvements in the electrification process of cars, several types of alternative fuel vehicles are appearing in the car market. However, these new engine technologies are not easily penetrating the market around the world and the conventional ones are still the leaders....... A vast literature has explored the reasons for such low market penetration, due mainly to car's features. Using a hybrid choice model approach, in this research we study if, and to which extent, habitual car use influences individual propensity to buy a specific type of engine technology. We found...... of a conventional one. The importance of taking into account this latent construct is demonstrated also with the results of the simulated elasticity measures. In fact, the exclusion of latent habitual effect significantly underestimates the elasticity of diesel and hybrid cars and overestimates the elasticity...

  7. Occasional, obligatory, and habitual stone tool use in hominin evolution.

    Science.gov (United States)

    Shea, John J

    2017-09-01

    Archeologists have long assumed that earlier hominins were obligatory stone tool users. This assumption is deeply embedded in traditional ways of describing the lithic record. This paper argues that lithic evidence dating before 1.7 Ma reflects occasional stone tool use, much like that practiced by nonhuman primates except that it involved flaked-stone cutting tools. Evidence younger than 0.3 Ma is more congruent with obligatory stone tool use, like that among recent humans. The onset of habitual stone tool use at about 1.7 Ma appears correlated with increased hominin logistical mobility (carrying things). The onset of obligatory stone tool use after 0.3 Ma may be linked to the evolution of spoken language. Viewing the lithic evidence dating between 0.3-1.7 Ma as habitual stone tool use explains previously inexplicable aspects of the Early-Middle Pleistocene lithic record. © 2017 Wiley Periodicals, Inc.

    Full Text Available Chronic biting of oral mucosa is an innocuous self inflicted injury, commonly seen in children suffering from developmental and psychological problems and has rarely been reported in normal unaffected individuals. The management strategies vary from counseling, prescription of sedatives to different prosthetic shields. The paper highlights the efficacy of a simple approach using soft mouth guard in the management of self inflicted lesions due to habitual biting of oral mucosa in two normal healthy children.

    2007-10-01

    Full Text Available La contracepción de emergencia puede evitar el embarazo luego de un coito sin medidas contraceptivas o cuando éstas fallan. Se recomienda el levonorgestrel, un gestágeno sintético, en dosis única de 1.5 mg (alternativamente en dos dosis de 0.75 mg espaciadas 12 h. Su eficacia es moderada, pues impide aproximadamente 80% de los embarazos. La eficacia es mayor cuanto más precozmente se administre, pero puede darse hasta 5 días post-coito. La tolerancia es similar o superior a la de otros preparados empleados con igual propósito. Los efectos adversos comprenden náuseas, vómitos, cefalea, tensión mamaria y alteraciones transitorias en la siguiente menstruación. Se desconoce si el levonorgestrel aumenta la probabilidad de embarazo ectópico cuando el tratamiento fracasa. No se recomienda su empleo como contraceptivo habitual. Cuando se administra antes del pico preovulatorio de LH, el levonorgestrel generalmente bloquea o retrasa la ovulación. Puede asimismo afectar la migración de los espermatozoides en el tracto genital femenino e, indirectamente, la fertilización. Pese a haberse postulado reiteradamente, no existe evidencia de un efecto antiimplantatorio. El conocimiento del método es muy variable en diferentes sociedades, pero aun donde es bien conocido permanece subutilizado. Se ha propuesto proveer levonorgestrel por adelantado para promover su uso. En ensayos clínicos, tal provisión no afectó adversamente el comportamiento sexual ni el empleo de otros contraceptivos, pero tampoco redujo el número de embarazos o abortos. En consecuencia, el empleo de levonorgestrel debe considerarse un método de respaldo que no reemplaza el uso de contraceptivos más eficaces.Emergency contraception may avoid pregnancy after unprotected intercourse or when regular contraceptive measures fail. Levonorgestrel, a synthetic gestagen, is recommended for emergency contraception as a single 1.5-mg dose or, alternatively, two 0.75-mg doses taken 12

    Learning, defined as a change in behaviour evoked by experience, has hitherto been investigated almost exclusively in multicellular neural organisms. Evidence for learning in non-neural multicellular organisms is scant, and only a few unequivocal reports of learning have been described in single-celled organisms. Here we demonstrate habituation, an unmistakable form of learning, in the non-neural organism Physarum polycephalum In our experiment, using chemotaxis as the behavioural output and quinine or caffeine as the stimulus, we showed that P. polycephalum learnt to ignore quinine or caffeine when the stimuli were repeated, but responded again when the stimulus was withheld for a certain time. Our results meet the principle criteria that have been used to demonstrate habituation: responsiveness decline and spontaneous recovery. To distinguish habituation from sensory adaptation or motor fatigue, we also show stimulus specificity. Our results point to the diversity of organisms lacking neurons, which likely display a hitherto unrecognized capacity for learning, and suggest that slime moulds may be an ideal model system in which to investigate fundamental mechanisms underlying learning processes. Besides, documenting learning in non-neural organisms such as slime moulds is centrally important to a comprehensive, phylogenetic understanding of when and where in the tree of life the earliest manifestations of learning evolved. © 2016 The Author(s).

A maioria das pesquisas está concentrada em hospitais públicos, com mulheres admitidas para tratamento do aborto incompleto, restringindo-se portanto aos abortos que apresentaram complicações. Descrevem o perfil das mulheres, métodos e razões para o aborto e conseqüências imediatas para a saúde física. Entretanto, permanecem limites relacionados à necessidade de estudos para mensuração da incidência do aborto; para investigação das especificidades dos óbitos por aborto e casos de morbidade grave; para análise da relação do aborto com anticoncepção; para investigação das repercussões do aborto na saúde mental das mulheres e para incorporação da perspectiva masculina. É urgente o desenvolvimento de pesquisas de avaliação da atenção ao aborto nos serviços públicos. Os resultados dos estudos devem ser divulgados, contribuindo para superar a visão ideologizada da discussão do direito ao aborto no país.This paper provides a review of abortion studies produced in the field of public health in Brazil, highlighting current research gaps and challenges. Most studies focus on women admitted to public hospitals for treatment of incomplete abortion, so their scope is limited to abortions presenting complications. Women's profiles, abortion methods, motives, and immediate consequences for women's physical health are also included. However, there remains a need for studies on the following aspects: measuring abortion incidence; investigating cases of post-abortion complications and death; analyzing the relationship between abortion and contraception; investigating the impact of abortion on women's mental health; and incorporating men's perspectives. There is an urgent need for evaluative research on abortion care in public services. Research results should be disseminated widely

    Full Text Available OBJETIVO: Conocer la percepción, recursos y prácticas que sobre el aborto tienen las parteras de un área rural mexicana, el Municipio de Yecapixtla, Morelos, situado en la parte central de México. MÉTODOS: Se utilizó método cualitativo, realizándose entrevistas en profundidad, grupos focales y observación participativa. Los tópicos indagados fueron aspectos socioculturales, sexualidad, reproducción y aspectos de salud en relación al aborto. Se entrevistó en profundidad a 9 parteras y se realizó un grupo focal en el que participaron 16 parteras. RESULTADOS: Éstos dan cuenta de una profunda actitud de rechazo ante el aborto, inducido o espontáneo. El primero se conceptúa como un pecado grave y el segundo como un fracaso en la principal función de la mujer en estas comunidades, la reproducción. Las mujeres que abortan son llamadas "puercas", "cochinas" o "perras" y las parteras se muestran reacias a atenderlas. Sin embargo, es común entre las mujeres de la comunidad la práctica de la "regulación de la regla", es decir, la utilización de sustancias que hacen que aparezca la menstruación si ésta se ha retrasado. Dicha práctica no se considera abortiva. CONCLUSIONES: El conocimiento del mundo de significaciones populares en torno al aborto es imprescindible para construir modelos y estrategias efectivas que, desde los servicios institucionales de salud, refuercen los vínculos entre éstos y las parteras tradicionales, de manera que se mejore el acceso a servicios y la calidad de la atención a las mujeres.

    Full Text Available O Código Penal Brasileiro existem permissibilidades para a realização de alguns procedimentos de abortamento, o chamado aborto legal. Nos casos de violência sexual, é assegurado o direito da mulher em optar por interromper a gestação. Mesmo que essa chamada permissão esteja garantida por lei e ratificada em normas ministeriais, ainda encontra-se morosidade em seu procedimento, uma vez que o profissional de saúde pode, em virtude das suas crenças morais ou religiosas, éticas ou/e filosóficas, optar pela “objeção de consciência”; essa escusa seria invocada a partir das representações desses sujeitos sobre o que seria o aborto legal. A partir desta realidade, o presente trabalho versou acerca de pesquisa em andamento dentro de uma maternidade de referência em procedimentos de abortamento legal na capital do Rio Grande do Norte. Buscou-se analisar as representações dos profissionais de saúde sobre as práticas de aborto legal, como também verificar como se organizam em torno da “objeção de consciência”; por meio de pesquisa qualitativa, com utilização de observação e entrevistas semiestruturadas.

    Full Text Available A través de la evolución de las tasas de fecundidad y embarazo por grupos de edad en España entre 1975 y 1995, se puede apreciar el descenso que se ha producido en ambos indicadores. Si bien la tendencia es idéntica, la cuantía del descenso difiere, pues se aprecia un descenso de mayor envergadura en las tasas de fecundidad que en las de embarazo, diferencia que se debe al aborto. El incremento del recurso al aborto desde la entrada en vigor de la ley que lo despenaliza es un rasgo común, aunque su importancia difiere dependiendo del grupo de edad. Así, la mayor proporción de embarazos finalizando en un aborto se observa entre las menores de veinticinco años y las mayores de cuarenta. El análisis contempla las diferencias entre comunidades autónomas, pudiéndose apreciar distintos comportamientos, principalmente en determinados grupos de edad.

    Full Text Available La educación médica en México tiene deficiencias importantes en el terreno de la salud sexual y reproductiva, y ofrece a los estudiantes pocos elementos para el reconocimiento del aborto como un problema relevante de la práctica profesional de la medicina. La educación médica carece de opciones para la capacitación clínica de los futuros médicos en modelos para la atención integral del aborto, que incluyen el uso de tecnologías seguras y eficaces, y una gama de servicios para responder a las necesidades de las mujeres. Estas limitaciones tienen especial relevancia en países como México, donde el aborto inseguro sigue siendo un importante problema de salud pública. Además, el marco legal del aborto ha empezado a cambiar en la década presente, por lo que la búsqueda de alternativas para incorporar un enfoque amplio sobre el aborto en los programas de las escuelas de medicina es una tarea que no se puede postergar.Medical education in Mexico has significant deficiencies in the area of sexual and reproductive health and does not offer students the information needed for dealing with abortion as a relevant problem in the professional practice of medicine. Medical education does not offer options for the clinical training of future physicians in integrated models for abortion care, which include the use of safe and effective technologies as well as a range of services to respond to women's needs. These limitations are especially relevant in countries such as Mexico where unsafe abortion continues to be a significant public health problem. In addition, the legal context for abortion has begun to change during the current decade; therefore, the search for alternatives to incorporate a broad approach to abortion in medical school programs is a task that cannot be postponed.

    de Wit, Sanne; Barker, Roger A; Dickinson, Anthony D; Cools, Roshan

    2011-05-01

    This study presents the first direct investigation of the hypothesis that dopamine depletion of the dorsal striatum in mild Parkinson disease leads to impaired stimulus-response habit formation, thereby rendering behavior slow and effortful. However, using an instrumental conflict task, we show that patients are able to rely on direct stimulus-response associations when a goal-directed strategy causes response conflict, suggesting that habit formation is not impaired. If anything our results suggest a disease severity-dependent deficit in goal-directed behavior. These results are discussed in the context of Parkinson disease and the neurobiology of habitual and goal-directed behavior.

    1977-01-01

    Astronauts, particularly in Skylab flights, experienced varying degrees of motion sickness lasting 3-5 days. One possible mechanism for this motion sickness adaptation is believed to be a reduction in otolith sensitivity with an attendant reduction in sensory conflict. In an attempt to determine if this hypothesis is valid, a ground-based pilot study was conducted on a vertical linear accelerator. The extent of habituation to accelerations which initially produced motion sickness was evaluated, along with the possible value of habituation training to minimize the space motion sickness problem. Results showed that habituation occurred for 6 of the 8 subjects tested. However, in tests designed to measure dynamic and static otolith function, no significant differences between pre- and post-habituation tests were observed. Cross habituation effects to a standard Coriolis acceleration test were not significant. It is unlikely that ground-based pre-habituation to linear accelerations of the type examined would alter susceptibility to space motion sickness.

It is included in the group of related idiopathic epilepsies with localization. Seizures habitually begin with visual symptoms, which are ocassionally followed by hemiclonic, complex partial, and generalized tonicclonic seizures. The interictal EEG shows spike-wave complexes of occipital and temporal posterior localization that are suppressed by eye opening. A patient aged 8 in whom the clinical and electroencephalographic criteria of epilepsy of childhood with occipital paroxysms are present is studied in this paper. Emphasis is made on the apparently benign evolution of this syndrome.

    The purpose of this study was to compare the effects of exercise habituation (3-32 years, mean 13.2 years) on physical vitality among five different groups. One hundred and two independent, community-dwelling elderly Japanese men, aged 64.6 +/- 6.6 years, were recruited as subjects. The vital age test battery consisted of various coronary heart disease risk factors and physical fitness elements. The results of analysis of variance revealed that vital age as an index of physical vitality was youngest in joggers (47.9 yr, N=18), intermediate in trekkers (55.8 yr, N=20) and walkers (59.1 yr, N=18), and oldest (69.6 yr, N=20) in patients with ischemic heart disease (IHD). The difference between chronological age and vital age was approximately 15 years (pexercising IHD patients. These results indicate that exercise habituation significantly affects the overall health status of most individuals, irrespective of mode of exercise. Among the three modes of exercise, jogging may be most beneficial. Furthermore, regularly exercising coronary patients may have physical vitality similar to that of sedentary men.

  9. Habitual intake of fruit juice predicts central blood pressure.

    Despite a common perception that fruit juice is healthy, fruit juice contains high amounts of naturally occurring sugar without the fibre content of the whole fruit. Frequent fruit juice consumption may therefore contribute to excessive sugar consumption typical of the Western society. Although excess sugar intake is associated with high blood pressure (BP), the association between habitual fruit juice consumption and BP is unclear. The present study investigated the association of fruit juice consumption with brachial and central (aortic) BP in 160 community dwelling adults. Habitual fruit juice consumption was measured using a 12 month dietary recall questionnaire. On the same day, brachial BP was measured and central (aortic) BP was estimated through radial artery applanation. Frequency of fruit juice consumption was classified as rare, occasional or daily. Those who consumed fruit juice daily, versus rarely or occasionally, had significantly higher central systolic BP (F (2, 134) = 6.09, p juice daily rather than rarely or occasionally. In conclusion, more frequent fruit juice consumption was associated with higher central BPs. Copyright © 2014 Elsevier Ltd. All rights reserved.

  10. Visual shape recognition in crayfish as revealed by habituation.

    Full Text Available To cope with the everyday challenges that they encounter in their evolutionary niche, crayfish are considered to rely mainly on chemical information or, alternatively, on tactile information, but not much on vision. Hence, research has focused on chemical communication, whereas crayfish visual abilities remain poorly understood and investigated. To fill in this gap, we tested whether crayfish (Procambarus clarkii can distinguish between two different visual shapes matched in terms of luminance. To this aim, we measured both the habituation response to a repeated presentation of a given shape, a downright Y, and the response recovery when a novel shape was presented. The novel shape could be either a Möbius or the same Y-shape but upright rotated. Our results demonstrate that, after habituation to the downright Y, crayfish showed a significantly higher response recovery to the Möbius as compared to the upright rotated Y. Hence, besides relying on chemo-haptic information, we found that crayfish can use sight alone to discriminate between different abstract geometrical shapes when macroscopically different. Failure to discriminate between the downright Y and its inversion or a generalization from the presence of a shape with three points creating a simple category, are both likely parsimonious explanations that should be investigated systematically in further studies. A future challenge will be understanding whether crayfish are capable of generalized shape recognition.

    Full Text Available Resumo O artigo objetiva analisar a produção científica sobre aborto e estigma social e o potencial da categoria estigma para estudos sobre a assistência ao abortamento no Brasil. Utilizou-se o método de revisão integrativa de publicações das bases científicas, optando por não estabelecer limite temporal. Analisou-se 65 publicações com as representações sociais de mulheres que abortam e de profissionais que as atendem; exploram os obstáculos para a implementação das leis do aborto e dos protocolos e normas que facilitariam o acesso a serviços de qualidade. À relevância conceitual de Erving Goffman somou-se a compreensão sobre a transgressão dos estereótipos de gênero, o imperativo da maternidade, a pureza sexual, que marca as mulheres que abortam como seres inferiores, deteriorados: promíscuas, pecadoras, assassinas. Identificaram-se grupos mais afetados pela estigmatização: mulheres em abortamento, profissionais de saúde. O conflito feminino pela dualidade ocultar/revelar seus abortamentos, a objeção de consciência de profissionais e os obstáculos na implementação de políticas públicas emergiram dos trabalhos. A reflexão sobre o papel do estigma pode interferir no ciclo do aborto clandestino e contribuir para o (re desenho de intervenções que apoiem a redução de danos à saúde sexual e reprodutiva das mulheres.

    Objective Research shows that slower habituation of salivary responses to food stimuli is related to greater energy intake and that obese (Ob) individuals habituate slower than those of normal weight (NW). No study has examined habituation rates in weight loss maintainers (WLMs) who have reduced from obese to normal weight, relative to those who are Ob or NW. Design Salivation to two baseline water trials and 10 lemon-flavored lollipop trials were studied in 14 WLMs, 15 Ob and 18 NW individuals comparable in age, gender and ethnicity. Linear mixed models were used to compare WLMs with Ob and NW groups. Results Salivation in the WLM and NW groups decreased significantly (for both P <0.005) across trials, indicative of habituation. Salivary responses in the Ob group did not habituate (P=0.46). When compared with Ob group, WLMs showed a quicker reduction in salivation (P<0.05). WLM and NW groups did not differ in habituation rate (P=0.49). Conclusions WLMs have habituation rates that are comparable to NW individuals without previous history of obesity, and show quicker habituation than those who are currently obese. These results suggest that physiological responses to food may ‘normalize’ with successful weight loss maintenance. PMID:20010900

    Micronutrient status is of fundamental importance both upon conception and throughout pregnancy. There is an abundance of literature investigating nutrient intakes during individual trimesters of pregnancy but few studies have investigated baseline intakes of nutrients throughout gestation as a continuum. The current investigation set out to measure habitual micronutrient intakes at weeks 13, 25, 35 of pregnancy and 6 weeks postpartum using a prospective background information questionnaire, 4-7-day weighed food diary and postnatal questionnaire. Seventy-two primiparous, Caucasian Londoners were recruited at the study start with 42 completing the first, second, third trimester and postpartum study stages respectively. Study findings indicated that sodium intakes were significantly higher than UK guidelines throughout and after pregnancy (P pregnancy, but to varying levels of statistical significance (P health interventions may be required to help expectant mothers achieve an optimal diet, particularly after birth when dietary recommendations increase for some micronutrients.

    Full Text Available O presente trabalho investigou os principais fatores de risco e preditores para o aborto induzido. Foi realizado um estudo transversal de base populacional com uma amostra representativa de 3.002 mulheres de 15 a 49 anos residentes no Sul do Brasil. Para responder as questões de aborto, as mulheres foram alocadas entre duas metodologias: método da urna ou método das questões indiretas. Informações sócio-econômicas, demográficas e reprodutivas foram obtidas por meio de um questionário pré-codificado. Na análise e interpretação dos dados utilizou-se o modelo de regressão logística. Teorema de Bayes foi aplicado para a determinação das probabilidades a posteriori permitindo a transformação dos dados agregados em dados individuais. Abortos induzidos estiveram fortemente relacionados com relatos de perda fetal em todas as idades. Entre as adolescentes, os principais preditores foram: pertencer a famílias de baixa renda, ter baixa escolaridade e alta evasão escolar, além de conhecerem um número maior de métodos contraceptivos. Para as mulheres de 20 a 49 anos de idade não houve diferença sócio-econômica, sendo que, estado civil e características reprodutivas, incluindo conhecimento de métodos contraceptivos, foram os fatores de risco freqüentes para o aborto induzido.This study aimed to identify key risk factors and predictors of induced abortion. A cross-sectional population-based study was conducted with a representative sample of 3,002 women 15 to 49 years of age in southern Brazil, randomly assigned to answer questions on induced abortion using either the ballot-box method or the indirect questioning method. Socioeconomic, demographic, and reproductive data were obtained through a pre-coded questionnaire. Data analysis used epidemiological statistical inferences and Bayes' theorem to calculate a posteriori probability. Induced abortion was strongly associated with fetal loss for all age groups.

    To compare electrical activity in the anterior temporal and masseter muscles on the habitual (HMS) and non-habitual mastication side (NHMS), during mastication and in the mandibular postural position. In addition, the increase in electrical activity during mastication was assessed for the HMS and NHMS, analysing both working (WSM) and non-working side during mastication (NWSM). A total of 28 healthy women (18-32 years) participated in the study. They were submitted to Kazazoglu's test to identify the HMS. Bioresearch 'Bio EMG' software and bipolar surface electrodes were used in the exams. The exams were conducted in the postural position and during the unilateral mastication of raisins, on both the HMS and NHMS. The working and non-working side on HMS and NHMS were assessed separately. The obtained data were then statistically analysed with SPSS 20.0, using the Paired Samples Test at a significance level of 95%. The differences in the average EMG values between HMS and NHMS were not statistically significant in the postural position (Temporal p=0.2; Masseter p=0.4) or during mastication (Temporal WSM p=0.8; Temporal NWSM p=0.8; Masseter WSM p=0.6; Masseter NWSM p=0.2). Differences in the increase in electrical activity between the masseter and temporal muscles occurred on the working side, on the HMS and NHMS (p=0.0), but not on the non-working side: HMS (p=0.9) and NHMS (p=0.3). The increase in electrical activity was about 35% higher in the masseter than in the temporal muscle. Mastication side preference does not significantly impact electrical activity of the anterior temporal and masseter muscles during mastication or in postural position. Copyright © 2016.

    The present experiment tested the effects of caffeine on acoustic startle habituation during different attention tasks in which subjects either (a) attended to the acoustic startle stimulus (auditory attention; n = 9) (b) attended to a visual search task during presentation of acoustic startle stimuli (visual attention; n = 10), or (c) were given no specific instructions during acoustic startle testing (no attention; n = 9). Startle eyeblink responses were measured after subjects received either caffeine (1 mg/kg) or placebo. Caffeine significantly delayed response habituation in the no attention group and in the auditory attention group, but had no effect on habituation in the visual attention group. These data show that startle habituation can occur with minimal attention being directed to the acoustic startle stimulus, and that visual attention cancels the effects of caffeine on startle habituation.

    1993-06-01

    The memory of hamsters (Mesocricetus auratus) for the flank scent of other male hamsters was investigated in a series of habituation experiments. In 2 types of habituation tasks (Experiments 1 and 2), male hamsters habituated to the flank scent of 1 male and then increased their level of investigation to that of a novel male; similar results were obtained when the intervals between trials ranged from 1 s to 2 days. When the test trial was 10 or 21 days after habituation (Experiment 3), males discriminated between familiar and novel flank scents at 10 days but not at 21 days. The results demonstrate recognition of familiar and unfamiliar individual odors and excellent memory for these differences. Habituation techniques yield extremely robust results and may be useful for investigations of other aspects of individual signatures.

    Habituated embryogenic line of pumpkin contained more CKs and IAA, but less ABA than the non-habituated line. Pronounced hypomethylation correlated with the absence of 2,4-D, addition of 5-azaC, and the process of habituation. A comparative analysis between habituated and non-habituated embryogenic cultures of pumpkin (Cucurbita pepo L.) in relation to endogenous phytohormones, global DNA methylation, and developmental and regeneration capacities of the cultures was conducted. The analysis revealed more cytokinins (CKs) and indole-3-acetic acid (IAA), but less abscisic acid (ABA) in the habituated HEC line than in the non-habituated DEC line. Ribosides and ribotides were the most abundant CK forms in both HEC and DEC lines (75.9 and 57.6 %, respectively). HEC contained more free-base CKs (5.8 vs. 3.2 %), whereas DEC contained considerably more O-glycosides (39.1 vs. 18.3 %). Although prevalence of IAA was common for both lines, relative ratio of CKs and ABA differed between DEC and HEC lines. ABA was prevailing over CKs in DEC, while CKs prevailed over ABA in HEC line. Taking into account the importance of ABA for embryo maturation, the reduced endogenous ABA content in HEC line might be the reason for a 5-fold reduction in regeneration capacity compared to DEC. Both habituated and non-habituated embryogenic lines were highly methylated in the presence of 2,4-dichlorophenoxyacetic acid (2,4-D). Pronounced hypomethylation correlated with the absence of 2,4-D, addition of 5-azacytidine (5-azaC), but also with the process of habituation. The habituated line was resistant to the effect of hypomethylation drug 5-azaC and remained highly methylated even after the addition of 5-azaC. Also, 5-azaC did not change the developmental pattern in the habituated line, indicating the existence of separate mechanisms by which 2,4-D influences global DNA methylation in comparison to habituation-related global DNA methylation.

  13. México 2006: El aborto de una prolongada transición a la democracia

    Full Text Available Se hace un breve recuento histórico del sistema político y de las principales reformas en el aparato electoral mexicano que condujeron al marco dentro del cual se realizaron las elecciones presidenciales de 2006. Se revisan los principales acontecimientos de este proceso electoral y del post-electoral, así como algunos de sus antecedentes. Se concluye que el principal problema de la llamada transición democrática en México es que se centró en reformas que establecieron reglas e instituciones electorales, pero que no transformaron el resto del sistema político y por tanto no se construyeron nuevas instituciones, relaciones de poder ni una renovada estructura del Estado que dieran lugar a una genuina democracia. Las instituciones electorales demostraron en 2006 su fragilidad interna, y una seria debilidad al no estar respaldadas por otras instituciones y relaciones que pudieran robustecerlas, como un auténtico Estado de derecho y una genuina división y equilibrio de poderes. Esto permitió que las instituciones electorales en 2006 cedieran a las presiones de los grupos que han detentado tradicionalmente el poder económico y político y que se resisten a una verdadera alternancia. El desafío en México es empezar de nuevo con una reforma del Estado que no sólo establezca reglas e instituciones electorales confiables, sino que vaya a fondo en la constitución de un sistema político integral y genuinamente democrático.

    Full Text Available Resumo Discute o aborto pelas perspectivas de mulheres internadas em uma maternidade pública de Salvador (BA. Enfatiza a observação participante do cotidiano do hospital e descreve trabalho de campo com técnicas de pesquisa qualitativa e quantitativa. Por perspectiva etnográfica, aborda a experiência hospitalar de mulheres diante da interrupção, voluntária ou não, da gravidez e apresenta o ponto de vista dos profissionais de saúde, argumentando que a forma pela qual a instituição estrutura a atenção ao aborto e os processos de simbolização a ela imbricados afetam profundamente as experiências das mulheres. Aponta que a discriminação contra as mulheres que abortam está integrada a estrutura, organização e cultura institucionais, e não apenas a ações individuais dos profissionais.

  15. Individual variation in habituation: behaviour over time toward different stimuli in threespine sticklebacks (Gasterosteus aculeatus)

    Habituation, or the relatively permanent waning of a response as a result of repeated stimulation, is a form of behavioural plasticity that allows animals to filter out irrelevant stimuli and to focus selectively on important stimuli. Individuals that fail to habituate might be at a disadvantage if they continue to respond to irrelevant stimuli; therefore, habituation can have adaptive significance. In this study we compared rates of behaviour over time toward three different ecologically-relevant stimuli (food, a male intruder and a gravid female) in threespine sticklebacks (Gasterosteus aculeatus). We detected evidence for habituation to the stimuli, and males in this study were especially aggressive toward both male and female conspecifics. Although there were some clear temporal patterns that could be detected by looking at average behaviour, not all individuals behaved in the same ‘average’ way. We detected substantial inter-individual variation in behaviour toward all three stimuli, inter-individual variation in rates of habituation to both male and female conspecifics, but no evidence for correlations between behaviours across stimuli (behavioural syndromes). These results suggest that individual animals vary in rates of habituation, and prompt hypotheses about the causes and consequences of variation in rates of habituation. PMID:25678715

  16. Habituation as an adaptive shift in response strategy mediated by neuropeptides

    Habituation is a non-associative form of learning characterized by a decremented response to repeated stimulation. It is typically framed as a process of selective attention, allowing animals to ignore irrelevant stimuli in order to free up limited cognitive resources. However, habituation can also occur to threatening and toxic stimuli, suggesting that habituation may serve other functions. Here we took advantage of a high-throughput Caenorhabditis elegans learning assay to investigate habituation to noxious stimuli. Using real-time computer vision software for automated behavioral tracking and optogenetics for controlled activation of a polymodal nociceptor, ASH, we found that neuropeptides mediated habituation and performed an RNAi screen to identify candidate receptors. Through subsequent mutant analysis and cell-type-specific gene expression, we found that pigment-dispersing factor (PDF) neuropeptides function redundantly to promote habituation via PDFR-1-mediated cAMP signaling in both neurons and muscles. Behavioral analysis during learning acquisition suggests that response habituation and sensitization of locomotion are parts of a shifting behavioral strategy orchestrated by pigment dispersing factor signaling to promote dispersal away from repeated aversive stimuli.

  17. "My worries are rational, climate change is not": habitual ecological worrying is an adaptive response.

    Full Text Available Qualifications such as "global warming hysteria" and "energy policy schizophrenia" put forward by some climate change skeptics, usually outside the academic arena, may suggest that people who seriously worry about the environment suffer from psychological imbalance. The present study aimed to refute this thesis. While habitual worrying in general is strongly associated with psychopathological symptoms, in a survey a near-zero correlation was found between habitual ecological worrying and pathological worry. Instead, habitual ecological worrying was associated with pro-environmental attitudes and behaviors, and with a personality structure characterized by imagination and an appreciation for new ideas. The study had sufficient statistical power and measures were valid and reliable. The results confirm that those who habitually worry about the ecology are not only lacking in any psychopathology, but demonstrate a constructive and adaptive response to a serious problem. In the public domain, these findings may contribute to a more rational and less emotional debate on climate change and to the prevention of stigmatization of people who are genuinely concerned about our habitat and are prepared to do something about it ("habitual worriers are not crazy". In the academic arena this study may contribute to environmental psychology ("habitual worrying is part of a green identity", as well as to the literature on worry and anxiety ("habitual worrying can be a constructive response".

    A deficit in amygdala habituation to repeated emotional stimuli may be an endophenotype of disorders characterized by emotion dysregulation, such as borderline personality disorder (BPD). Amygdala reactivity to emotional stimuli is genetically modulated by brain-derived neurotrophic factor (BDNF) variants. Whether amygdala habituation itself is also modulated by BDNF genotypes remains unknown. We used imaging-genetics to examine the effect of BDNF Val66Met genotypes on amygdala habituation to repeated emotional stimuli. We used functional magnetic resonance imaging (fMRI) in 57 subjects (19 BPD patients, 18 patients with schizotypal personality disorder [SPD] and 20 healthy controls [HC]) during a task involving viewing of unpleasant, neutral, and pleasant pictures, each presented twice to measure habituation. Amygdala responses across genotypes (Val66Met SNP Met allele-carriers vs. Non-Met carriers) and diagnoses (HC, BPD, SPD) were examined with ANOVA. The BDNF 66Met allele was significantly associated with a deficit in amygdala habituation, particularly for emotional pictures. The association of the 66Met allele with a deficit in habituation to unpleasant emotional pictures remained significant in the subsample of BPD patients. Using imaging-genetics, we found preliminary evidence that deficient amygdala habituation may be modulated by BDNF genotype. Copyright © 2017. Published by Elsevier B.V.

    Habitual exercise is associated with enhanced domain-general cognitive control, such as inhibitory control, selective attention, and working memory, all of which rely on the frontal cortex. However, whether regular exercise is associated with more specific aspects of cognitive control, such as the cognitive control of emotion, remains relatively unexplored. The present study employed a correlational design to determine whether level of habitual exercise was related to performance on the Stroop test measuring selective attention and response inhibition, the cognitive reappraisal task measuring cognitive reappraisal success, and associated changes in prefrontal cortex (PFC) oxygenation using functional near-infrared spectroscopy. 74 individuals (24 men, 50 women, age 18-32 years) participated. Higher habitual physical activity was associated with lower Stroop interference (indicating greater inhibitory control) and enhanced cognitive reappraisal success. Higher habitual exercise was also associated with lower oxygenated hemoglobin (O 2 Hb) in the PFC in response to emotional information. However, NIRS data indicated that exercise was not associated with cognitive control-associated O 2 Hb in the PFC. Behaviorally, the findings support and extend the previous findings that habitual exercise relates to more successful cognitive control of neutral information and cognitive reappraisal of emotional information. Future research should explore whether habitual exercise exerts causal benefits to cognitive control and PFC oxygenation, as well as isolate specific cognitive control processes sensitive to change through habitual exercise.

  20. Attentional Bias Associated with Habitual Self-Stigma in People with Mental Illness.

    As habitual self-stigma can have a tremendous negative impact on people with mental illness, it is of paramount importance to identify its risk factors. The present study aims to examine the potential contributory role of attentional bias in habitual self-stigma. People with mental illness having strong (n = 47) and weak (n = 47) habitual self-stigma completed a computerized emotional Stroop task which included stigma-related, positive, and non-affective words as stimuli. The strong habit group was found to exhibit faster color-naming of stigma-related words (compared to non-affective words), whereas the weak habit group showed no difference in the speed of response to different stimuli. These findings suggest that people with stronger habitual self-stigma may be more able to ignore the semantic meaning of stigma-related words and focus on the color-naming task. Moreover, people with stronger habitual self-stigma may have greater attentional avoidance of stigma-related material. The present study is the first to demonstrate a specific relationship between habitual self-stigma and biased processing of stigma-related information. In order to further determine the role and the nature of attentional bias in habitual self-stigma, future research should employ a broader range of experimental paradigms and measurement techniques to examine stigma-related attentional bias in people with mental illness.

    Full Text Available Background: Abnormalities in habituation have been documented in Autism Spectrum Disorder (ASD and Williams syndrome (WS. Such abnormalities have been proposed to underlie the distinctive social and non-social difficulties that define ASD, including sensory features and repetitive behaviours, and the distinctive social phenotype characterizing WS. Methods: We measured habituation in 39 preschoolers with ASD, 20 peers with WS and 19 typically developing (TD children using an eye-tracking protocol that measured participants’ duration of attention in response to a repeating stimulus and a novel stimulus presented side by side across multiple trials. Results: Participants in the TD group and the WS group decreased their attention toward the repeating stimulus and increased their attention to the novel stimulus over time. Conversely, the ASD group showed a similar attentional response to the novel and repeating stimuli. Habituation was correlated with social functioning in the WS but not in the ASD group. Contrary to predictions, slower habituation in ASD was associated with lower severity of repetitive behaviours. Conclusions: Habituation appears to be intact in WS and impaired in ASD. More research is needed to clarify the nature of the syndrome-specific patterns of correlations between habituation and social and non-social functioning in these neurodevelopmental disorders.

    2014-07-01

    Shear loading rates (LR) have not been investigated in runners with a mid- or forefoot strike (FFS) versus rearfoot strike (RFS). The purpose of this study was to compare three-dimensional ground reaction forces (GRF) and LR during impact in habitual rearfoot strikers (hRF) and habitual forefoot strikers (hFF) strikers. Thirty competitive runners performed 10 overground running trials with both foot strike styles. Peak three-dimensional and resultant GRF and instantaneous LR during impact were compared. Vertical LR significantly decreased for hRF using an FFS (RFS = 148 ± 36 body weight [BW]·s(-1), FFS = 98 ± 31 BW·s(-1)) but was similar for hFF running with either foot strike (FFS = 136 ± 35 BW·s(-1), RFS = 135 ± 28 BW·s(-1)). Posterior impact forces were present during FFS but not during RFS, and posterior LR was significantly greater for both groups during FFS (-58 ± 17 vs -19 ± 6 BW·s(-1)). Medial impact forces were also present during FFS but not during RFS, and medial LR was significantly larger for both groups during FFS (-21 ± 7 vs -6 ± 6 BW·s(-1)). Interestingly, hFF had greater impact peaks and LR in all directions compared with hRF during FFS. This may be explained by hFF using a smaller strike index (hFF = 62% ± 9%, hRF = 67% ± 9%; P = 0.02), which was significantly inversely related to vertical LR and impact peak. Peak resultant and vertical LR are not ubiquitously lower when using a shod FFS versus RFS despite an absence of resultant and vertical impact peaks. Furthermore, there were impact peaks in the posterior and medial directions, leading also to greater LR in these directions during FFS. Therefore, transitioning from RFS to FFS in traditional running shoes may not offer long-term protection against impact-related running injuries because hFF running with an FFS demonstrated many GRF and LR similar to or greater than RFS.

    The transition from goal-directed actions to habitual ethanol seeking models the development of addictive behavior that characterizes alcohol use disorders. The progression to habitual ethanol-seeking behavior occurs more rapidly than for natural rewards, suggesting that ethanol may act on habit circuit to drive the loss of behavioral flexibility. This review will highlight recent research that has focused on the formation and expression of habitual ethanol seeking, and the commonalities and distinctions between ethanol and natural reward-seeking habits, with the goal of highlighting important, understudied research areas that we believe will lead toward the development of novel treatment and prevention strategies for uncontrolled drinking.

  5. Goal-directed, habitual and Pavlovian prosocial behavior

    2015-05-01

    Full Text Available Although prosocial behaviors have been widely studied across disciplines, the mechanisms underlying them are not fully understood. Evidence from psychology, biology and economics suggests that prosocial behaviors can be driven by a variety of seemingly opposing factors: altruism or egoism, intuition or deliberation, inborn instincts or learned dispositions, and utility derived from actions or their outcomes. Here we propose a framework inspired by research on reinforcement learning and decision making that links these processes and explains characteristics of prosocial behaviors in different contexts. More specifically, we suggest that prosocial behaviors inherit features of up to three decision-making systems employed to choose between self- and other- regarding acts: a goal-directed system that selects actions based on their predicted consequences, a habitual system that selects actions based on their reinforcement history, and a Pavlovian system that emits reflexive responses based on evolutionarily prescribed priors. This framework, initially described in the field of cognitive neuroscience and machine learning, provides insight into the potential neural circuits and computations shaping prosocial behaviors. Furthermore, it identifies specific conditions in which each of these three systems should dominate and promote other- or self- regarding behavior.

    Why do people gamble? A large body of research suggests that cognitive distortions play an important role in pathological gambling. Many of these distortions are specific cases of a more general misperception of randomness, specifically of an illusory perception of patterns in random sequences. In this article, we provide further evidence for the assumption that gamblers are particularly prone to perceiving illusory patterns. In particular, we compared habitual gamblers to a matched sample of community members with regard to how much they exhibit the choice anomaly 'probability matching'. Probability matching describes the tendency to match response proportions to outcome probabilities when predicting binary outcomes. It leads to a lower expected accuracy than the maximizing strategy of predicting the most likely event on each trial. Previous research has shown that an illusory perception of patterns in random sequences fuels probability matching. So does impulsivity, which is also reported to be higher in gamblers. We therefore hypothesized that gamblers will exhibit more probability matching than non-gamblers, which was confirmed in a controlled laboratory experiment. Additionally, gamblers scored much lower than community members on the cognitive reflection task, which indicates higher impulsivity. This difference could account for the difference in probability matching between the samples. These results suggest that gamblers are more willing to bet impulsively on perceived illusory patterns.

    Full Text Available A 3-year-old male child was brought by his parents with a nonhealing ulcer on the right middle finger having no significant history except for an injury sustained to the right elbow in December 2013. On further probing, the mother revealed that the child used to indulge in habitual biting of his right middle finger while watching TV. Initially he was investigated extensively by a vascular surgeon and no abnormality was detected. He was later referred to the dermatology department and on examination, the patient was attentive with normal behaviour. The right upper limb was slightly larger than left. There was no deformity of the right elbow. The right third fingertip was enlarged and mutilated. There was no nerve thickening or hypopigmented patch. There was loss of sensation on the right hand and arm. Differential diagnosis of Lesch–Nyhan syndrome and congenital sensory neuropathy were considered. The patient was referred to a neurologist who investigated further with magnetic resonance imaging (MRI, and the final diagnosis of syringomyelia was made based on MRI findings.

    Organizational change is a particularly emotional event for those being confronted with it. Anger is a frequently experienced emotion under these conditions. This study analyses the influence of employees' habitual anger reactions on their reported behavior during organizational change. It was explored whether anger reactions conducive to recovering or increasing individual well-being will enhance the likelihood of functional change behavior. Dysfunctional regulation strategies in terms of individual well-being are expected to decrease the likelihood of functional change behavior-mediated by the commitment to change. Four hundred and twelve employees of different organizations in Luxembourg undergoing organizational change participated in the study. Findings indicate that the anger regulation strategy venting, and humor increase the likelihood of deviant resistance to change. Downplaying the incident's negative impact and feedback increase the likelihood of active support for change. The mediating effect of commitment to change has been found for humor and submission. The empirical findings suggest that a differentiated conceptualization of resistance to change is required. Specific implications for practical change management and for future research are discussed.

    Habit formation is a behavioral adaptation that automates routine actions. Habitual behavior correlates with broad reconfigurations of dorsolateral striatal (DLS) circuit properties that increase gain and shift pathway timing. The mechanism(s) for these circuit adaptations are unknown and could be responsible for habitual behavior. Here we find that a single class of interneuron, fast-spiking interneurons (FSIs), modulates all of these habit-predictive properties. Consistent with a role in habits, FSIs are more excitable in habitual mice compared to goal-directed and acute chemogenetic inhibition of FSIs in DLS prevents the expression of habitual lever pressing. In vivo recordings further reveal a previously unappreciated selective modulation of SPNs based on their firing patterns; FSIs inhibit most SPNs but paradoxically promote the activity of a subset displaying high fractions of gamma-frequency spiking. These results establish a microcircuit mechanism for habits and provide a new example of how interneurons mediate experience-dependent behavior.

  13. Habituation and adaptation of the vestibuloocular reflex: a model of differential control by the vestibulocerebellum

    1992-01-01

    We habituated the dominant time constant of the horizontal vestibuloocular reflex (VOR) of rhesus and cynomolgus monkeys by repeated testing with steps of velocity about a vertical axis and adapted the gain of the VOR by altering visual input with magnifying and reducing lenses. After baseline values were established, the nodulus and ventral uvula of the vestibulocerebellum were ablated in two monkeys, and the effects of nodulouvulectomy and flocculectomy on VOR gain adaptation and habituation were compared. The VOR time constant decreased with repeated testing, rapidly at first and more slowly thereafter. The gain of the VOR was unaffected. Massed trials were more effective than distributed trials in producing habituation. Regardless of the schedule of testing, the VOR time constant never fell below the time constant of the semicircular canals (approximately 5 s). This finding indicates that only the slow component of the vestibular response, the component produced by velocity storage, was habituated. In agreement with this, the time constant of optokinetic after-nystagmus (OKAN) was habituated concurrently with the VOR. Average values for VOR habituation were obtained on a per session basis for six animals. The VOR gain was adapted by natural head movements in partially habituated monkeys while they wore x 2.2 magnifying or x 0.5 reducing lenses. Adaptation occurred rapidly and reached about +/- 30%, similar to values obtained using forced rotation. VOR gain adaptation did not cause additional habituation of the time constant. When the VOR gain was reduced in animals with a long VOR time constant, there were overshoots in eye velocity that peaked at about 6-8 s after the onset or end of constant-velocity rotation. These overshoots occurred at times when the velocity storage integrator would have been maximally activated by semicircular canal input. Since the activity generated in the canals is not altered by visual adaptation, this finding indicates that the gain

    Qualifications such as "global warming hysteria" and "energy policy schizophrenia" put forward by some climate change skeptics, usually outside the academic arena, may suggest that people who seriously worry about the environment suffer from psychological imbalance. The present study aimed to refute this thesis. While habitual worrying in general is strongly associated with psychopathological symptoms, in a survey a near-zero correlation was found between habitual ecological worrying and path...

The common forms of migraine are characterized interictally by a habituation deficit of cortical and subcortical evoked responses that has...... been attributed to neuronal dysexcitability. FHM and the common forms of migraine are thought to belong to a spectrum of migraine phenotypes with similar pathophysiology, and we therefore examined whether an abnormal habituation pattern would also be found in FHM patients....

    Full Text Available Este artículo describe la ilegalidad del aborto en Colombia cuya población forma parte del 0,4% mundial que vive en países donde el aborto está totalmente prohibido. La penalización absoluta hace de este un problema de salud pública generador de inequidad social. En las decisiones reproductivas la legislación siempre ha desconocido a las mujeres como personas, y enfrentada a una concepción integral sobre derechos sexuales y reproductivos, los proyectos de ley apenas se refieren a las situaciones "moralmente inaceptables" - embarazo por violación - o a razones terapéuticas. Las contradicciones entre la ilegalidad y la realidad permiten mantener un discurso público de rechazo frente al aborto (posición dominante de la jerarquía eclesiástica, mientras que en la práctica, se recurre a la interrupción voluntaria de la gestación en condiciones de seguridad y confianza al menos entre las mujeres de los estratos socioeconómicos más altos. Esto no sólo genera inequidad social, sino que refleja la forma en que las leyes van perdiendo sentido, creando en el imaginario colectivo la impresión de que no sirven ni son necesarias, debilitando el Estado en su función normativa.This article discusses the illegality of abortion in Colombia, situating this country within the 0.4% of the world population where abortion is completely banned. Absolute criminalization of abortion turns it into a public health matter and produces social inequality. The Colombian legislation has always disregarded women as individuals and as persons in full possession of their legal rights. In contrast to a comprehensive conceptualization of sexual and reproductive rights, the various abortion bills merely refer either to "morally unacceptable" situations such as pregnancy resulting from rape or to therapeutic motives. Contradictions between illegality and reality give rise to a public discourse that features rejection of abortion practices, in keeping with the

    Low dietary fibre intake has been associated with poorer health outcomes, therefore having the ability to be able to quickly assess an individual's dietary fibre intake would prove useful in clinical practice and for research purposes. Current dietary assessment methods such as food records and food frequency questionnaires are time-consuming and burdensome, and there are presently no published short dietary fibre intake questionnaires that can quantify an individual's total habitual dietary fibre intake and classify individuals as low, moderate or high habitual dietary fibre consumers. Therefore, we aimed to develop and validate a habitual dietary fibre intake short food frequency questionnaire (DFI-FFQ) which can quickly and accurately classify individuals based on their habitual dietary fibre intake. In this study the DFI-FFQ was validated against the Monash University comprehensive nutrition assessment questionnaire (CNAQ). Fifty-two healthy, normal weight male (n = 17) and female (n = 35) participants, aged between 21 and 61 years, completed the DFI-FFQ twice and the CNAQ once. All eligible participants completed the study, however the data from 46% of the participants were excluded from analysis secondary to misreporting. The DFI-FFQ cannot accurately quantify total habitual dietary fibre intakes, however, it is a quick, valid and reproducible tool in classifying individuals based on their habitual dietary fibre intakes.

    Individuals with anxiety disorders have previously demonstrated abnormal habituation to aversiveness over time. As anxiety sensitivity (AS), or an individuals' propensity to fear of anxiety-related sensations, has been shown to be a risk factor for anxiety disorders (particularly panic disorder), the present study examined whether AS was also associated with abnormal habituation. This association was examined in two independent samples of undergraduates (Ntotal=178). Habituation was operationalised as the reduction in startle response to multiple startle probes presented over 2.5 minutes and three definitions of this reduction were employed. Results indicated that individuals with higher levels of AS evidenced deficits in startle habituation, but the strength of this relationship was somewhat dependent on the definition of startle habituation, with the most robust definition being an analysis of participants' individual slopes across all nine blinks. The present findings suggest that startle habituation is a key mechanism underlying AS, and may help elucidate the role this risk factor plays in the pathogenesis of anxiety disorders.

    Habitual midday napping is a common habit in China, especially for pregnant women. The purpose of this study was to examine whether duration and frequency of maternal habitual midday napping were associated with high birthweight (HBW). A total of 10,482 participants from Healthy Baby Cohort were include in our analysis. The information of the mothers and their infants were abstracted from medical records, or obtained from questionnaire. Logistic regression models were used to calculate the odds ratios (ORs) and 95% confidence intervals (CIs) of habitual midday napping duration and frequency with HBW. Of the participants, 8,705 (83.0%) reported having habitual midday napping. Duration and frequency of napping had a positive association with HBW without adjustment. After controlling for potential confounders, increasing risk of HBW was observed in participants who napped 1.5-2 hours (OR, 1.50, 95% CI, 1.14, 1.98), and ≥2 hours (OR, 1.35, 95% CI, 1.03, 1.78) compared with no habitual midday napping. Participants who took naps ≥5 days/week had a higher risk of HBW (OR, 1.37, 95% CI, 1.07, 1.77) compared with the women without naps. This suggests that longer (≥1.5 hours) and more frequent (≥5 days/week) maternal habitual midday napping were associated with an increased risk of HBW.

  1. Objectively determined habitual physical activity in South African adolescents: the PAHL study

    Background There is limited data on objectively determined habitual physical activity (PA) in 16-year old South African adolescents. The purpose of this study was to objectively determine the habitual PA of adolescents from the North West Province of South Africa by race and gender. Methods Adolescents (137 girls, 89 boys) from the ongoing Physical Activity and Health Longitudinal Study (PAHL study), participated in the present study. Habitual PA was objectively recorded by means of the Actiheart® over a period of 7 days. Time spent in moderate-to-vigorous intensity physical activity (MVPA) was assessed. Results Average MVPA for the study sample was 50.9 ± 40.3 minutes/day. Girls were significantly more active than boys expending more time in MVPA (61.13 ± 52.2 minutes/day; p Physical activity varies by both gender and race in adolescents from the North West Province of South Africa. Objectively determined data from our study indicates that girls habitually spend more time in MVPA per day than boys, and that white adolescents habitually engage in more MVPA than black adolescents. Seeing as the average MVPA per day for the entire study sample falls below the recommended daily average of 60minutes/day, adolescents should be the foremost targets of interventions aimed at enhancing habitual PA.

    Using a randomized control group trial the long-term efficacy of a habituation-based treatment as conceived by Jastreboff, and a cognitive-behavioural tinnitus coping training were compared. An educational intervention was administered as a control condition. Both treatments were conducted in a group format (habituation-based treatment, 5 sessions; tinnitus coping training, 11 sessions). Educational intervention was delivered in a single group session. Patients were categorized according to their level of disability due to tinnitus (low, high), age and gender and then randomly allocated to the treatment conditions (habituation-based treatment, n = 30; tinnitus coping training, n = 27; educational intervention, n = 20). Data assessment included follow-ups of up to 21 months. Several outcome variables including disability due to tinnitus were assessed either by questionnaire or diary. Findings reveal highly significant improvements in both tinnitus coping training and habituation-based treatment in comparison with the control group. While tinnitus coping training and habituation-based treatment do not differ significantly in reduction of tinnitus disability, improvement in general well-being and adaptive behaviour is greater in tinnitus coping training than habituation-based treatment. The decrease in disability remains stable throughout the last follow-up in both treatment conditions.

  4. Psychological correlates of habitual diet in healthy adults.

    Stevenson, Richard J

    2017-01-01

    There are 3 motivations for studying the psychological correlates of habitual diet. First, diet is a major but modifiable cause of morbidity and mortality, and dietary interventions could be improved by knowing the psychological characteristics of consumers of healthy/unhealthy diets. Second, animal studies indicate that diet can impair cognition, stress responsiveness, and affective processing, but it is unclear whether this also happens in humans. Third, certain psychological traits are associated with obesity, but it is not known whether these precede and thus contribute to weight gain. Although many psychological correlates of diet have been identified, the literature is highly dispersed, and there has been no previous comprehensive narrative review. Organized here by psychological domain, studies linking diet with individual differences in perception, cognition, impulsivity, personality, affective processing, mental health, and attitudes, beliefs and values-in healthy adults-are reviewed. Although there is a growing literature on the psychological correlates of fruit/vegetable intake-the core of a healthy diet-consumers of unhealthy diets have characteristics that probably make them less responsive to education-based interventions. Diet may be a causal contributor to depression, and diet is consistently linked to impulsivity and certain personality traits. There are inconsistent and less explored links to perceptual, affective and cognitive processes, with several emerging parallels to the animal literature. Impulsivity and personality traits common to obese individuals also occur in lean consumers of unhealthy diets, suggesting these may contribute to weight gain. Diet-psychology correlates remain understudied even though this could significantly benefit human health. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

    Full Text Available This study aimed to assess total energy expenditure (TEE and specific habitual physical activities in adolescent sprint athletes. Two methods used to estimate TEE, an activity diary (AD and SenseWear armband (SWA, were compared. Sixteen athletes (6 girls, 10 boys, mean age 16.5 ± 1.6 yr simultaneously wore a SWA and completed an AD and food diary during one week. Basal energy expenditure as given by the SWA when taken off was corrected for the appropriate MET value using the AD. TEE as estimated by the AD and SWA was comparable (3196 ± 590 kcal and 3012 ± 518 kcal, p = 0.113 without day-to-day variations in TEE and energy expended in activities of high intensity. Daily energy intake (2569 ± 508 kcal did not match TEE according to both the AD and SWA (respectively p < 0.001 and p = 0.007. Athletes were in a supine position for a longer time on weekend days than on week days and slept longer on Sundays. Athletes reported a longer time of high-intensive physical activities in the AD than registered by the SWA on 4 out of 7 days. In addition to specific sprint activities on 3 to 7 days per week, 11 out of 16 athletes actively commuted to school where they participated in sports once or twice per week. The AD and the SWA are comparable in the estimation of TEE, which appears realistic and sustainable. The SWA offers an appropriate and objective method in the assessment of TEE, sleeping and resting in adolescent athletes on the condition that detailed information is given for the times the armband is not worn. The AD offers activity specific information but relies on the motivation, compliance and subjectivity of the individual, especially considering high-intensive intermittent training

    Full Text Available International successions have often raised controversies for Private International Law. This paper deals with the general ground of jurisdiction of the deceased’s last habitual residence. In this field, the flexible, fluid and changing concept of the last “habitual residence” of the deceased needs an appropriate interpretation both for academics and for the practitioners of Private International Law. However, this essay holds that the liquidity of the concept “habitual residence” of the deceased may be an advantage to grant international jurisdiction on the courts which are best placed to rule on the merits of the case. Moreover, this paper sustains that a careful and holistic interpretation of the text of the Regulation and a proper analysis of the function of this ground of international jurisdiction leads to a surprising conclusion, i.e., the concept of the “habitual residence” is not as complex and difficult to specify as, at first glance, it might appear.

    Full Text Available Infectious abortion is a significant cause of reproductive failure and economic losses in cattle. The goal of this study was to detect nucleic acids of several infectious agents known to cause abortion including Arcanobacterium pyogenes, Bovine Herpesvirus 1, Brucella abortus, Campylobacter fetus subsp. venerealis, Chlamydophila abortus, Leptospira sp., Listeria monocytogenes, Salmonella sp., Mycoplasma bovis, Mycoplasma bovigenitalium, Neospora caninum, and Tritrichomonas foetus. Tissue homogenates from 42 fetuses and paraffin-embedded tissues from 28 fetuses and 14 placentas/endometrium were included in this study. Brucella abortus was detected in 14.2% (12/84 of the samples. Salmonella sp. DNA was amplified from 2 fetuses, and there was one positive for Neospora caninum, and another for Listeria monocytogenes. This PCR-based approach resulted in identification of the etiology in 19% of samples, or 20% if considered fetal tissues only.Aborto infeccioso é uma causa significativa de falhas reprodutivas e perdas econômicas na bovinocultura.

  10. Effects of temperature on heat pain adaptation and habituation in men and women.

    2010-12-01

    We recently reported that women report greater pain adaptation and habituation to moderately painful heat stimuli than men (Hashmi and Davis [16]); but slightly lower temperatures were needed to evoke moderate pain in the women. Hardy et al (1962) and LaMotte (1979) suggested that pain adaptation is most prominent at modest noxious heat temperatures and may occur at temperatures close to pain thresholds. Thus, as a follow-up to our previous study, we examined the role of absolute temperature in pain adaptation and habituation in men and women and assessed whether pain threshold impacts these findings. We hypothesised that pain adaptation and habituation would be more prominent at low and moderate temperatures, and that higher temperatures would induce pain adaptation and habituation in women but not in men. We further hypothesized that pain adaptation would not be correlated with pain thresholds. To test this, we obtained continuous ratings of pain evoked by 44.5-47.5°C stimuli applied to the dorsal foot of men and women. Each run consisted of three 30s stimuli at the same temperature with a 60s inter-stimulus interval. Women showed within-stimulus adaptation of total pain at all temperatures, but men showed significant adaptation to temperatures less than 47°C. There were no sex differences in inter-stimulus habituation and both men and women reported habituation to temperatures less than 46°C. Pain thresholds did not correlate with pain adaptation. These data highlight the temperature-sensitivity and sex differences of pain adaptation and habituation. Copyright © 2010 International Association for the Study of Pain. Published by Elsevier B.V.

    This study examined the influence of feminist attitudes on self-objectification, habitual body monitoring, and body dissatisfaction in middle age and older women. The participants were 138 European American heterosexual women ranging in age from 40 to 87 years old. Consistent with previous research, self-objectification and habitual body monitoring were positively correlated with body dissatisfaction and, self-objectification and habitual body monitoring remained stable across the lifespan. While age did not moderate the relationship between self-objectification and body dissatisfaction, age was found to moderate the relationship between habitual body monitoring and body dissatisfaction such that the relationship was smaller for older women than for middle-aged women. Interestingly, feminist attitudes were not significantly correlated with body dissatisfaction, self-objectification, or habitual body monitoring, and endorsement of feminist attitudes was not found to moderate the relationship between self-objectification or habitual body monitoring and body dissatisfaction. Potential implications for older women are discussed.

    Habits tend to form slowly but, once formed, can have great stability. We probed these temporal characteristics of habitual behaviors by intervening optogenetically in forebrain habit circuits as rats performed well-ingrained habitual runs in a T-maze. We trained rats to perform a maze habit, confirmed the habitual behavior by devaluation tests, and then, during the maze runs (ca. 3 s), we disrupted population activity in a small region in the medial prefrontal cortex, the infralimbic cortex. In accordance with evidence that this region is necessary for the expression of habits, we found that this cortical disruption blocked habitual behavior. Notably, however, this blockade of habitual performance occurred on line, within an average of three trials (ca. 9 s of inhibition), and as soon as during the first trial (habit, and, simultaneously, the more recently acquired habit was blocked. These online changes occurred within an average of two trials (ca. 6 s of infralimbic inhibition). Measured changes in generalized performance ability and motivation to consume reward were unaffected. This immediate toggling between breaking old habits and returning to them demonstrates that even semiautomatic behaviors are under cortical control and that this control occurs online, second by second. These temporal characteristics define a framework for uncovering cellular transitions between fixed and flexible behaviors, and corresponding disturbances in pathologies. PMID:23112197

  13. Competitive short-term and long-term memory processes in spatial habituation.

    2011-04-01

    Exposure to a spatial location leads to habituation of exploration such that, in a novelty preference test, rodents subsequently prefer exploring a novel location to the familiar location. According to Wagner's (1981) theory of memory, short-term and long-term habituation are caused by separate and sometimes opponent processes. In the present study, this dual-process account of memory was tested. Mice received a series of exposure training trials to a location before receiving a novelty preference test. The novelty preference was greater when tested after a short, rather than a long, interval. In contrast, the novelty preference was weaker when exposure training trials were separated by a short, rather than a long interval. Furthermore, it was found that long-term habituation was determined by the independent effects of the amount of exposure training and the number of exposure training trials when factors such as the intertrial interval and the cumulative intertrial interval were controlled. A final experiment demonstrated that a long-term reduction of exploration could be caused by a negative priming effect due to associations formed during exploration. These results provide evidence against a single-process account of habituation and suggest that spatial habituation is determined by both short-term, recency-based memory and long-term, incrementally strengthened memory.

    This study is designed to compare the habitual pitch measured in two different speech activities (free play activity and traditionally used structured speech activity) for normally developing preschool-aged children to explore to what extent preschoolers vary their vocal pitch among different speech environments. Habitual pitch measurements were conducted for 10 normally developing children (2 boys, 8 girls) between the ages of 31 months and 71 months during two different activities: (1) free play; and (2) structured speech. Speech samples were recorded using a throat microphone connected with a wireless transmitter in both activities. The habitual pitch (in Hz) was measured for all collected speech samples by using voice analysis software (Real-Time Pitch). Significantly higher habitual pitch is found during free play in contrast to structured speech activities. In addition, there is no showing of significant difference of habitual pitch elicited across a variety of structured speech activities. Findings suggest that the vocal usage of preschoolers appears to be more effortful during free play than during structured activities. It is recommended that a comprehensive evaluation for young children's voice needs to be based on the speech/voice samples collected from both free play and structured activities.

    Habituation and sensitization are important behavioural responses to repeated exposure to painful stimuli, but little is known about the factors determining sensory, affective and sympathetic habituation to repeated pain stimulation in men and women. Thirty volunteers (15 women) underwent a standardized heat pain paradigm spread over 8 consecutive days. At the beginning of the experiment, personality dimensions, coping strategies and pain catastrophizing thoughts were determined. Receiving a series of 10 blocks of six painful heat stimuli a day, participants rated pain intensity and unpleasantness. Skin conductance was recorded throughout the sessions. The results show similar habituation of both the sensory and affective dimensions of pain in men and women, although skin conductance did not undergo a significant decrease across the eight days. When focusing on single daily sessions, women showed pain sensitization but sympathetic habituation, while men showed pain sensitization but stable sympathetic activation. Our findings therefore indicate that the process of long-term habituation to painful heat stimuli is a common feature in both genders, whereas men and women might differently recruit their sympathetic nervous system for short-term pain processing. This study could potentially help to better evaluate gender-specific mechanisms in pain perception. © 2012 European Federation of International Association for the Study of Pain Chapters.

    Familiarity with stimuli that bring neither reward nor punishment, manifested through behavioral habituation, enables organisms to detect novelty and devote cognition to important elements of the environment. Here we describe in mice a form of long-term behavioral habituation to visual grating stimuli that is selective for stimulus orientation. Orientation-selective habituation (OSH) can be observed both in exploratory behavior in an open arena and in a stereotyped motor response to visual stimuli in head-restrained mice. We found that the latter behavioral response, termed a 'vidget', requires V1. Parallel electrophysiological recordings in V1 revealed that plasticity, in the form of stimulus-selective response potentiation (SRP), occurred in layer 4 of V1 as OSH developed. Local manipulations of V1 that prevented and reversed electrophysiological modifications likewise prevented and reversed memory demonstrated behaviorally. These findings suggest that a form of long-term visual recognition memory is stored via synaptic plasticity in primary sensory cortex.

    To investigate familial clustering of habitual constipation in pediatric patients who attended our medical facilities. Children with the diagnosis of functional, habitual constipation or patients without constipation and their respective family members were prospectively recruited to our study. Constipation was established in all participants using a standard questionnaire (Rome criteria). A total of 112 children and their families participated in the study, of which 37 were probands families (test) and 75 children and their respective family members constituted the control group. A total of 310 family members completed the questionnaire. No significant differences were found between the study and the control groups in age, sex, or family size. Siblings or parents from the study group (probands) had significantly higher rates of constipation compared with the control group (30% vs 7% and 42% vs 9%, respectively; P = 0.001). Habitual constipation in children seemed to cluster in families. The pathophysiology behind this phenomenon is yet unknown.

    To assess the impact of match-start time and days relative to match compared with the habitual sleep characteristics of elite Australian Football (AF) players. 45 elite male AF players were assessed during the preseason (habitual) and across 4 home matches during the season. Players wore an activity monitor the night before (-1), night of (0), 1 night after (+1), and 2 nights (+2) after each match and completed a self-reported rating of sleep quality. A 2-way ANOVA with Tukey post hoc was used to determine differences in sleep characteristics between match-start times and days relative to the match. Two-way nested ANOVA was conducted to examine differences between competition and habitual phases. Effect size ± 90% confidence interval (ES ± 90% CI) was calculated to quantify the magnitude of pairwise differences. Differences observed in sleep-onset latency (ES = 0.11 ± 0.16), sleep rating (ES = 0.08 ± 0.14), and sleep duration (ES = 0.08 ± 0.01) between competition and habitual periods were trivial. Sleep efficiency was almost certainly higher during competition than habitual, but this was not reflected in the subjective rating of sleep quality. Elite AF competition does not cause substantial disruption to sleep characteristics compared with habitual sleep. While match-start time has some impact on sleep variables, it appears that the match itself is more of a disruption than the start time. Subjective ratings of sleep from well-being questionnaires appear limited in their ability to accurately provide an indication of sleep quality.

    A ubiquitous feature of an animal's response to an odorant is that it declines when the odorant is frequently or continuously encountered. This decline in olfactory response, termed olfactory habituation, can have temporally or mechanistically different forms. The neural circuitry of the fruit fly Drosophila melanogaster's olfactory system is well defined in terms of component cells, which are readily accessible to functional studies and genetic manipulation. This makes it a particularly useful preparation for the investigation of olfactory habituation. In addition, the insect olfactory system shares many architectural and functional similarities with mammalian olfactory systems, suggesting that olfactory mechanisms in insects may be broadly relevant. In this chapter, we discuss the likely mechanisms of olfactory habituation in context of the participating cell types, their connectivity, and their roles in sensory processing. We overview the structure and function of key cell types, the mechanisms that stimulate them, and how they transduce and process odor signals. We then consider how each stage of olfactory processing could potentially contribute to behavioral habituation. After this, we overview a variety of recent mechanistic studies that point to an important role for potentiation of inhibitory synapses in the primary olfactory processing center, the antennal lobe, in driving the reduced response to familiar odorants. Following the discussion of mechanisms for short- and long-term olfactory habituation, we end by considering how these mechanisms may be regulated by neuromodulators, which likely play key roles in the induction, gating, or suppression of habituated behavior, and speculate on the relevance of these processes for other forms of learning and memory. © 2014 Elsevier B.V.

    The effect of habituation at reduced water activity (aw) on heat tolerance of Salmonella spp. was investigated. Stationary-phase cells were exposed to aw 0.95 in broths containing glucose-fructose, sodium chloride, or glycerol at 21°C for up to a week prior to heat challenge at 54°C. In addition, the effects of different aws and heat challenge temperatures were investigated. Habituation at aw 0.95 resulted in increased heat tolerance at 54°C with all solutes tested. The extent of the increase and the optimal habituation time depended on the solute used. Exposure to broths containing glucose-fructose (aw 0.95) for 12 h resulted in maximal heat tolerance, with more than a fourfold increase in D54 values. Cells held for more than 72 h in these conditions, however, became as heat sensitive as nonhabituated populations. Habituation in the presence of sodium chloride or glycerol gave rise to less pronounced but still significant increases in heat tolerance at 54°C, and a shorter incubation time was required to maximize tolerance. The increase in heat tolerance following habituation in broths containing glucose-fructose (aw 0.95) was RpoS independent. The presence of chloramphenicol or rifampin during habituation and inactivation did not affect the extent of heat tolerance achieved, suggesting that de novo protein synthesis was probably not necessary. These data highlight the importance of cell prehistory prior to heat inactivation and may have implications for food manufacturers using low-aw ingredients. PMID:11055944

    Chronic sleep loss has been associated with increased daytime sleepiness, as well as impairments in memory and attentional processes. In the present study, we evaluated the neuronal changes of a pre-attentive process of wake auditory sensory gating, measured by brain event-related potential (ERP)--P50 in eight normal sleepers (NS) (habitual total sleep time (TST) 7 h 32 m) vs. eight chronic short sleeping individuals (SS) (habitual TST ≤6 h). To evaluate the effect of sleep extension on sensory gating, the extended sleep condition was performed in chronic short sleeping individuals. Thus, one week of time in bed (6 h 11 m) corresponding to habitual short sleep (hSS), and one week of extended time (∼ 8 h 25 m) in bed corresponding to extended sleep (eSS), were counterbalanced in the SS group. The gating ERP assessment was performed on the last day after each sleep condition week (normal sleep and habitual short and extended sleep), and was separated by one week with habitual total sleep time and monitored by a sleep diary. We found that amplitude of gating was lower in SS group compared to that in NS group (0.3 µV vs. 1.2 µV, at Cz electrode respectively). The results of the group × laterality interaction showed that the reduction of gating amplitude in the SS group was due to lower amplitude over the left hemisphere and central-midline sites relative to that in the NS group. After sleep extension the amplitude of gating increased in chronic short sleeping individuals relative to their habitual short sleep condition. The sleep condition × frontality interaction analysis confirmed that sleep extension significantly increased the amplitude of gating over frontal and central brain areas compared to parietal brain areas.

    The objective of this study was to investigate the associations between objectively measured habitual sleep duration (HSD), habitual sleep variability (HSV), and energy and snack intake in adolescents. We used data from 324 adolescents who participated in the Penn State Child Cohort follow-up examination. Actigraphy was used over seven consecutive nights to estimate nightly sleep duration. The seven-night mean and standard deviation of sleep duration were used to represent HSD and HSV, respectively. The Youth/Adolescent Food Frequency Questionnaire was used to obtain the daily average total energy, protein, fat, and carbohydrate intake, and number of snacks consumed. Linear regression models were used to investigate the associations between habitual sleep patterns and caloric, protein, fat, and carbohydrate intake. Proportional odds models were used to associate habitual sleep patterns with snack consumption. After adjusting for age, sex, race, body mass index (BMI) percentile, and smoking status, an increased HSV was associated with a higher energy intake, particularly from fat and carbohydrate. For example, with a 1-h increase in HSV, there was a 170 (66)-kcal increase in the daily total energy intake. An increased HSV was also related to increased snack consumption, especially snacks consumed after dinner. For instance, a 1-h increase in HSV was associated with 65% and 94% higher odds of consuming more snacks after dinner during school/workdays and weekends/vacation days, respectively. Neither energy intake nor snack consumption was significantly related to HSD. High habitual sleep variability, not habitual sleep duration, is related to increased energy and food consumption in adolescents. Maintaining a regular sleep pattern may decrease the risk of obesity in adolescents. Copyright © 2015 Elsevier B.V. All rights reserved.

    This study examined the links between desensitization to violent media stimuli and habitual media violence exposure as a predictor and aggressive cognitions and behavior as outcome variables. Two weeks after completing measures of habitual media violence exposure, trait aggression, trait arousability, and normative beliefs about aggression, undergraduates (N = 303) saw a violent film clip and a sad or a funny comparison clip. Skin conductance level (SCL) was measured continuously, and ratings of anxious and pleasant arousal were obtained after each clip. Following the clips, participants completed a lexical decision task to measure accessibility of aggressive cognitions and a competitive reaction time task to measure aggressive behavior. Habitual media violence exposure correlated negatively with SCL during violent clips and positively with pleasant arousal, response times for aggressive words, and trait aggression, but it was unrelated to anxious arousal and aggressive responding during the reaction time task. In path analyses controlling for trait aggression, normative beliefs, and trait arousability, habitual media violence exposure predicted faster accessibility of aggressive cognitions, partly mediated by higher pleasant arousal. Unprovoked aggression during the reaction time task was predicted by lower anxious arousal. Neither habitual media violence usage nor anxious or pleasant arousal predicted provoked aggression during the laboratory task, and SCL was unrelated to aggressive cognitions and behavior. No relations were found between habitual media violence viewing and arousal in response to the sad and funny film clips, and arousal in response to the sad and funny clips did not predict aggressive cognitions or aggressive behavior on the laboratory task. This suggests that the observed desensitization effects are specific to violent content.

    Optimal behavioral performance results from a balance between goal-directed and habitual systems of behavioral control, which are modulated by ascending monoaminergic projections. While the role of the dopaminergic system in behavioral control has been recently addressed, the extent to which changes in global serotonin neurotransmission could influence these 2 systems is still poorly understood. We employed the dietary acute tryptophan depletion procedure to reduce serotonin neurotransmission in 18 healthy volunteers and 18 matched controls. We used a 3-stage instrumental learning paradigm that includes an initial instrumental learning stage, a subsequent outcome-devaluation test, and a slip-of-action stage, which directly tests the balance between hypothetical goal-directed and habitual systems. We also employed a separate response inhibition control test to assess the behavioral specificity of the results. Acute tryptophan depletion produced a shift of behavioral performance towards habitual responding as indexed by performance on the slip-of-action test. Moreover, greater habitual responding in the acute tryptophan depletion group was predicted by a steeper decline in plasma tryptophan levels. In contrast, acute tryptophan depletion left intact the ability to use discriminative stimuli to guide instrumental choice as indexed by the instrumental learning stage and did not impair inhibitory response control. The major implication of this study is that serotonin modulates the balance between goal-directed and stimulus-response habitual systems of behavioral control. Our findings thus imply that diminished serotonin neurotransmission shifts behavioral control towards habitual responding. © The Author 2015. Published by Oxford University Press on behalf of CINP.

    Background The aim of this study was to examine the effects of a 6-week training program of simulated barefoot running (SBR) on running kinetics in habitually shod (wearing shoes) female recreational runners. Material/Methods Twelve female runners age 25.7±3.4 years gradually increased running distance in Vibram FiveFingers minimal shoes over a 6-week period. The kinetic analysis of treadmill running at 10 Km/h was performed pre- and post-intervention in shod running, non-habituated SBR, and habituated SBR conditions. Spatiotemporal parameters, ground reaction force components, and electromyography (EMG) were measured in all conditions. Results Post-intervention data indicated a significant decrease across time in the habituation SBR for EMG activity of the tibialis anterior (TA) in the pre-activation and absorptive phase of running (Prunning, unhabituated SBR, and habituated SBR. Six weeks of SBR was associated with a significant decrease in the loading rates and impact forces. Additionally, SBR significantly decrease the stride length, step duration, and flight time, and stride frequency was significantly higher compared to shod running. Conclusions The findings of this study indicate that changes in motor patterns in previously habitually shod runners are possible and can be accomplished within 6 weeks. Non-habituation SBR did not show a significant neuromuscular adaptation in the EMG activity of TA and GAS as manifested after 6 weeks of habituated SBR. PMID:26166443

Paradoxalmente, é justamente nesses países que observam-se os menores danos à Saúde da Mulher enquanto que, mesmo pautando-se em dados pouco ou nada confiáveis, o custo da prática clandestina é altíssimo: suas sequelas são bastante frequentes e, não raras vezes, levam ao óbito. Avaliar-se o quão alto é este custo, contudo, é uma tarefa bastante árdua e, infelizmente, dependendo do enfoque desejado pode até ser inexequível. A solução mais acertada para a resolução desse dilema seria, a julgar pela literatura especializada, legalizar-se o aborto. Nessa eventualidade, além de se reduzir, automaticamente, os custos da prática clandestina, a análise do dueto Aborto/ Saúde, por si, permitiria remover os custos remanecentes.Mas, enquanto se convive com uma legislação restritiva, a solução mais sensata, é buscar otimizar a qualidade de análise daquele dueto.

    Performing a prospective memory task repeatedly changes the nature of the task from episodic to habitual. The goal of the present study was to investigate the neural basis of this transition. In two experiments, we contrasted event-related potentials (ERPs) evoked by correct responses to prospective memory targets in the first, more episodic part of the experiment with those of the second, more habitual part of the experiment. Specifically, we tested whether the early, middle, or late ERP-components, which are thought to reflect cue detection, retrieval of the intention, and post-retrieval processes, respectively, would be changed by routinely performing the prospective memory task. The results showed a differential ERP effect in the middle time window (450–650 ms post-stimulus). Source localization using low resolution brain electromagnetic tomography analysis suggests that the transition was accompanied by an increase of activation in the posterior parietal and occipital cortex. These findings indicate that habitual prospective memory involves retrieval processes guided more strongly by parietal brain structures. In brief, the study demonstrates that episodic and habitual prospective memory tasks recruit different brain areas. PMID:25071519

    Violation of unconditioned stimulus (US) expectancy during extinction training may enhance associative learning and result in improved long-term extinction retention compared to within-session habituation. This experiment examines variation in US expectancy (i.e., expectancy violation) as a predictor of long-term extinction retention. It also examines within-session habituation of fear-potentiated startle (electromyography, EMG) and fear of conditioned stimuli (CS) throughout extinction training as predictors of extinction retention. Participants (n = 63) underwent fear conditioning, extinction and retention and provided continuous ratings of US expectancy and EMG, as well as CS fear ratings before and after each phase. Variation in US expectancy throughout extinction and habituation of EMG and fear was entered into a regression as predictors of retention and reinstatement of levels of expectancy and fear. Greater variation in US expectancy throughout extinction training was significantly predictive of enhanced extinction performance measured at retention test, although not after reinstatement test. Slope of EMG and CS fear during extinction did not predict retention of extinction. Within-session habituation of EMG and self-reported fear is not sufficient for long-term retention of extinction learning, and models emphasizing expectation violation may result in enhanced outcomes.

    Body exposure is a common and effective treatment for body image disturbance in bulimia nervosa (BN). However, little is known about treatment mechanisms. Based on models of emotional processing and neurovisceral integration, we expected to observe a) initial activation and b) habituation of cognitive-affective and autonomic responding within one and between two standardized body exposure sessions. A group of 13 women with BN and 13 healthy controls (HC) were repeatedly exposed to their bodies. Prior to and after treatment with three individualized mirror exposure sessions participants received a session of standardized exposure to videographic recordings of their body. Subjective ratings of body-related emotions and thoughts were assessed repeatedly throughout the standardized exposure sessions and autonomic responses were recorded continuously. Subjective and sympathetic responses were activated initially in both groups. Cognitive-affective responses habituated within the standardized sessions in both groups, whereas between the standardized sessions habituation was only found in women with BN. Increasing sympathetic responses were found within the sessions in both groups. The results support cognitive-affective habituation during body exposure in BN and to a lesser extent in HC. Autonomic responses however did not show a corresponding pattern and did not distinguish between groups. Implications for body exposure research and practice are discussed.

    Running is one of the most accessible physical activities and running with and without footwear has attracted extensive attention in the past several years. In this study 18 habitually male unshod runners and 20 habitually male shod runners (all with dominant right feet) participated in a running test. A Vicon motion analysis system was used to capture the kinematics of each participant's lower limb. The in-shoe plantar pressure measurement system was employed to measure the pressure and force exerted on the pressure sensors of the insole. The function of a separate hallux in unshod runners is analyzed through the comparison of plantar pressure parameters. Owing to the different strike patterns in shod and unshod runners, peak dorsiflexion and plantarflexion angle were significantly different. Habitually shod runners exhibited a decreased foot strike angle (FSA) under unshod conditions; and the vertical average loading rate (VALR) of shod runners under unshod conditions was larger than that under shod conditions. This suggests that the foot strike pattern is more important than the shod or unshod running style and runners need to acquire the technique. It can be concluded that for habitually unshod runners the separate hallux takes part of the foot loading and reduces loading to the forefoot under shod conditions. The remaining toes of rearfoot strike (RFS) runners function similarly under unshod conditions. These morphological features of shod and unshod runners should be considered in footwear design to improve sport performance and reduce injury. Copyright © 2015 Elsevier B.V. All rights reserved.

    Runners are often categorized as forefoot, midfoot or rearfoot strikers, but how much and why do individuals vary in foot strike patterns when running on level terrain? This study used general linear mixed-effects models to explore both intra- and inter-individual variations in foot strike pattern among 48 Kalenjin-speaking participants from Kenya who varied in age, sex, body mass, height, running history, and habitual use of footwear. High speed video was used to measure lower extremity kinematics at ground contact in the sagittal plane while participants ran down 13 meter-long tracks with three variables independently controlled: speed, track stiffness, and step frequency. 72% of the habitually barefoot and 32% of the habitually shod participants used multiple strike types, with significantly higher levels of foot strike variation among individuals who ran less frequently and who used lower step frequencies. There was no effect of sex, age, height or weight on foot strike angle, but individuals were more likely to midfoot or forefoot strike when they ran on a stiff surface, had a high preferred stride frequency, were habitually barefoot, and had more experience running. It is hypothesized that strike type variation during running, including a more frequent use of forefoot and midfoot strikes, used to be greater before the introduction of cushioned shoes and paved surfaces.

    1. The initial respiratory and cardiac responses to cold water immersion are thought to be responsible for a significant number of open water deaths each year. Previous research has demonstrated that the magnitude of these responses can be reduced by repeated immersions in cold waterwhether the site of habituation is central or peripheral. 2. Two groups of subjects undertook two 3 min head-out immersions in stirred water at 10 C of the right-hand side of the body (R). Between these two immersions (3 whole days) the control group (n = 7) were not exposed to cold water, but the habituation group (n = 8) undertook a further six 3 min head-out immersions in stirred water at 10 C of the left-hand side of the body (L). 3. Repeated L immersions reduced (P immersion a reduction (P < 0.05) in the magnitude of the responses evoked was seen in the habituation group but not in the control group, despite both groups having identical skin temperature profiles. 4. It is concluded that the mechanisms involved in producing habituation of the initial responses are located more centrally than the peripheral receptors.

    2010-10-01

    Habituation to novel environments is frequently studied to analyze cognitive phenotypes in animals, and an open-field test is generally conducted to investigate the changes that occur in animals during habituation. The test has not been used in behavioral studies of medaka (Oryzias latipes), which is recently being used in behavioral research. Therefore, we examined the open-field behavior of medaka on the basis of temporal changes in 2 conventional indexes of locomotion and position. The findings of our study clearly showed that medaka changed its behavior through multiple temporal phases as it became more familiar with new surroundings; this finding is consistent with those of other ethological studies in animals. During repeated open-field testing on 2 consecutive days, we observed that horizontal locomotion on the second day was less than that on the first day, which suggested that habituation is retained in fish for days. This temporal habituation was critically affected by water factors or visual cues of the tank, thereby suggesting that fish have spatial memory of their surroundings. Thus, the data from this study will afford useful fundamental information for behavioral phenotyping of medaka and for elucidating cognitive phenotypes in animals. Copyright (c) 2010 Elsevier B.V.

  16. Evidence for habituation of the irrelevant-sound effect on serial recall.

    Röer, Jan P; Bell, Raoul; Buchner, Axel

    2014-05-01

    Working memory theories make opposing predictions as to whether the disruptive effect of task-irrelevant sound on serial recall should be attenuated after repeated exposure to the auditory distractors. Although evidence of habituation has emerged after a passive listening phase, previous attempts to observe habituation to to-be ignored distractors on a trial-by-trial basis have proven to be fruitless. With the present study, we suggest that habituation to auditory distractors occurs, but has often been overlooked because past attempts to measure habituation in the irrelevant-sound paradigm were not sensitive enough. In a series of four experiments, the disruptive effects of to-be-ignored speech and music relative to a quiet control condition were markedly reduced after eight repetitions, regardless of whether trials were presented in blocks (Exp. 1) or in a random order (Exp. 2). The auditory distractor's playback direction (forward, backward) had no effect (Exp. 3). The same results were obtained when the auditory distractors were only presented in a retention interval after the presentation of the to-be-remembered items (Exp. 4). This pattern is only consistent with theoretical accounts that allow for attentional processes to interfere with the maintenance of information in working memory.

  17. Competition with Variety Seeking and Habitual Consumption: Price Commitment or Quality Commitment?

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available This paper investigates price and quality competition in a market where consumers seek variety and habit formation. Variety seeking is modeled as a decrease in the willingness to pay for product purchased on the previous occasion while habitual consumption may increase future marginal utility. We compare two competing strategies: price commitment and quality commitment. With a three-stage Hotelling-type model, we show that variety seeking intensifies while habitual consumption softens the competition. With price commitment, firms supply lower quality levels in period 1 and higher quality levels in period 2, while, with quality commitment, firms charge higher prices in period 1 and lower prices in period 2. However, the habitual consumption brings the opposite effect. In addition, with quality commitment variety seeking leads to a lower profit and a higher consumer surplus, while habitual consumption leads to the opposite results. On the other side, with price commitment these behaviors have no effect on the consumer surplus, although they still lower down the firm profits. Finally, we also identify conditions under which one strategy outperforms the other.

    Inadequate sleep and psychological stress can both elevate physiological stress markers, such as cortisol. Prior studies that have applied induced psychosocial stress after a night of experimental sleep deprivation have found these effects to be compounded. We examined whether the relationship between stress reactivity and poor sleep also extends to habitual sleep patterns. Fifty-nine adult male participants were recruited. Habitual sleep patterns were monitored with actigraphy for a week. Participants subsequently underwent the Trier Social Stress Test. Cardiovascular responses and salivary cortisol were measured at baseline, during stress, and during recovery. Subjects who showed poor habitual sleep efficiency during the week before stress induction responded with higher stress-related elevations of blood pressure and cortisol levels as compared to subjects with high sleep efficiency. This relationship between poor sleep efficiency and elevated blood pressure persisted during the post-stress recovery period. Similar associations between total sleep time in the week prior to the stress induction and physiological reactivity did not reach significance. Our findings indicate that habitual low sleep efficiency exaggerates cardiovascular and neuroendocrine effects of psychosocial stress, in a male population. Copyright © 2017 Elsevier Ltd.

    Visual clutter imposes significant challenges to older adults in everyday tasks and often calls on selective processing of relevant information. Previous research has shown that both visual search habits and task goals influence older adults' allocation of spatial attention, but has not examined the relative impact of these two sources of attention when they compete. To examine how aging affects the balance between goal-driven and habitual attention, and to inform our understanding of different attentional subsystems, we tested young and older adults in an adapted visual search task involving a display laid flat on a desk. To induce habitual attention, unbeknownst to participants, the target was more often placed in one quadrant than in the others. All participants rapidly acquired habitual attention toward the high-probability quadrant. We then informed participants where the high-probability quadrant was and instructed them to search that screen location first-but pitted their habit-based, viewer-centered search against this instruction by requiring participants to change their physical position relative to the desk. Both groups prioritized search in the instructed location, but this effect was stronger in young adults than in older adults. In contrast, age did not influence viewer-centered search habits: the two groups showed similar attentional preference for the visual field where the target was most often found before. Aging disrupted goal-guided but not habitual attention. Product, work, and home design for people of all ages--but especially for older individuals--should take into account the strong viewer-centered nature of habitual attention.

    Previous studies have demonstrated a profound lack of habituation in 129P3 mice compared to the habituating, but initially more anxious, BALB/c mice. The present study investigated whether this non-adaptive phenotype of 129P3 mice is primarily based on anxiety-related characteristics. To test this hypothesis and extend our knowledge on the behavioural profile of 129P3 mice, the effects of the anxiolyticdiazepam (1, 3 and 5 mg/kg) and the putative anxiolytic metabotropic glutamate receptor 5 (mGlu5R) antagonist 2-methyl-6-(phenylethynyl)pyridine (MPEP, 3, 10 and 30 mg/kg) treatment on within-trial (intrasession) habituation, object recognition (diazepam: 1 mg/kg; MPEP 10 mg/kg) and on the central-nervous expression of the immediate early gene c-Fos (diazepam: 1 mg/kg; MPEP 10 mg/kg) were investigated. Behavioural findings validated the initially high, but habituating phenotype of BALB/c mice, while 129P3 mice were characterized by impaired intrasession habituation. Diazepam had an anxiolytic effect in BALB/c mice, while in higher doses caused behavioural inactivity in 129P3 mice. MPEP revealed almost no anxiolytic effects on behaviour in both strains, but reduced stress-induced corticosterone responses only in 129P3 mice. These results were complemented by reduced expression of c-Fos after MPEP treatment in brain areas related to emotional processes, and increased c-Fos expression in higher integrating brain areas such as the prelimbic cortex compared to vehicle-treated 129P3 mice. These results suggest that the strain differences observed in (non)adaptive anxiety behaviour are at least in part mediated by differences in gamma-aminobutyric acid- A and mGluR5 mediated transmission.

    Endurance running may have a long evolutionary history in the hominin clade but it was not until very recently that humans ran wearing shoes. Research on modern habitually unshod runners has suggested that they utilize a different biomechanical strategy than runners who wear shoes, namely that barefoot runners typically use a forefoot strike in order to avoid generating the high impact forces that would be experienced if they were to strike the ground with their heels first. This finding suggests that our habitually unshod ancestors may have run in a similar way. However, this research was conducted on a single population and we know little about variation in running form among habitually barefoot people, including the effects of running speed, which has been shown to affect strike patterns in shod runners. Here, we present the results of our investigation into the selection of running foot strike patterns among another modern habitually unshod group, the Daasanach of northern Kenya. Data were collected from 38 consenting adults as they ran along a trackway with a plantar pressure pad placed midway along its length. Subjects ran at self-selected endurance running and sprinting speeds. Our data support the hypothesis that a forefoot strike reduces the magnitude of impact loading, but the majority of subjects instead used a rearfoot strike at endurance running speeds. Their percentages of midfoot and forefoot strikes increased significantly with speed. These results indicate that not all habitually barefoot people prefer running with a forefoot strike, and suggest that other factors such as running speed, training level, substrate mechanical properties, running distance, and running frequency, influence the selection of foot strike patterns.

  9. Modification of Male Courtship Motivation by Olfactory Habituation via the GABAA Receptor in Drosophila melanogaster

    A male-specific component, 11-cis-vaccenyl acetate (cVA) works as an anti-aphrodisiac pheromone in Drosophila melanogaster. The presence of cVA on a male suppresses the courtship motivation of other males and contributes to suppression of male-male homosexual courtship, while the absence of cVA on a female stimulates the sexual motivation of nearby males and enhances the male-female interaction. However, little is known how a male distinguishes the presence or absence of cVA on a target fly from either self-produced cVA or secondhand cVA from other males in the vicinity. In this study, we demonstrate that male flies have keen sensitivity to cVA; therefore, the presence of another male in the area reduces courtship toward a female. This reduced level of sexual motivation, however, could be overcome by pretest odor exposure via olfactory habituation to cVA. Real-time imaging of cVA-responsive sensory neurons using the neural activity sensor revealed that prolonged exposure to cVA decreased the levels of cVA responses in the primary olfactory center. Pharmacological and genetic screening revealed that signal transduction via GABAA receptors contributed to this olfactory habituation. We also found that the habituation experience increased the copulation success of wild-type males in a group. In contrast, transgenic males, in which GABA input in a small subset of local neurons was blocked by RNAi, failed to acquire the sexual advantage conferred by habituation. Thus, we illustrate a novel phenomenon in which olfactory habituation positively affects sexual capability in a competitive environment. PMID:26252206

    When exposed to a cold environment, a barehanded person experiences pain, cold sensation, and reduced manual dexterity. Both acute (e.g. exercise) and chronic (e.g. cold acclimatization or habituation) processes might lessen these negative effects. The purpose of this experiment was to determine the effect of cold habituation on physiology, perception, and manual dexterity during rest, exercise, and recovery in 5 °C. Six cold weather athletes (CWA) and eight non habituated men (NON) volunteered to participate in a repeated measures cross-over design. The protocol was conducted in 5 °C and was 90 min of resting cold exposure, 30 min of cycle ergometry exercise (50 % VO2 peak), and 60 min of seated recovery. Core and finger skin temperature, metabolic rate, Purdue Pegboard dexterity performance, hand pain, thermal sensation, and mood were quantified. Exercise-induced finger rewarming (EIFRW) was calculated for each hand. During 90 min of resting exposure to 5 °C, the CWA had a smaller reduction in finger temperature, a lower metabolic rate, less hand pain, and less negative mood. Despite this cold habituation, dexterity performance was not different between groups. In response to cycle ergometry, EIFRW was greater in CWA (~12 versus 7 °C) and occurred at lower core temperatures (37.02 versus 37.31 °C) relative to NON but dexterity was not greater during post-exercise recovery. The current data indicate that cold habituated men (i.e., CWA) do not perform better on the Purdue Pegboard during acute cold exposure. Furthermore, despite augmented EIFRW in CWA, dexterity during post-exercise recovery was similar between groups.

  12. Gravidez imprevista e aborto no Rio de Janeiro, Brasil: gênero e geração nos processos decisórios

    Directory of Open Access Journals (Sweden)

    Maria Luiza Heilborn

    Full Text Available O artigo apresenta resultados da pesquisa HEXCA - Brasil, que investigou, por meio de entrevistas em profundidade, a interrupção da gravidez nas trajetórias biográficas de 31 mulheres e 28 homens de classes populares e médias e diferentes faixas etárias (18 a 27 e 40 a 49 anos. Abordam-se os processos de negociação e tomada de decisão acerca do aborto. Tais processos revelam-se portadores de temporalidades distintas, não lineares, e condicionados por circunstâncias sociais variadas. A análise dos processos de decisão seguiu o exame das relações de gênero narradas pelos informantes, bem como a condição da etapa de vida em que o evento da interrupção da gravidez teve lugar. O contraste geracional permitiu observar, nos estratos sociais pesquisados, mudanças significativas nas relações de gênero e familiares, nas representações acerca da maternidade, paternidade e reprodução, e nos métodos e no acesso ao abortamento nas últimas décadas. A perspectiva biográfica adotada mostrou-se fecunda ao vincular o evento analisado ao curso das experiências sexuais, contraceptivas e reprodutivas dos entrevistados.

  13. De la maternidad elegida a no ser madre (por ahora: anticoncepción y aborto en la vida de las mujeres

    Susana Rostagnol

    Full Text Available Este artículo analiza las formas en que mujeres procuran elegir el momento de su maternidad, y las maneras en que combinan sus prácticas reproductivas en el marco de su sexualidad. La norma conceptiva habla de un tiempo para la maternidad que se inscribe dentro de una serie de requisitos, los cuales, si bien son sociales, marcan las expectativas de las propias mujeres; el tipo de pareja y el momento vital aparecen entre los más importantes. Se examinan las prácticas anticonceptivas de mujeres según los tipos de relación de pareja en que se encuentran; el lugar ocupado por la medicalización de los cuerpos; y la relación entre la anticoncepción y los embarazos no esperados. Emergen marcadas diferencias en los significados y prácticas reproductivas entre mujeres de estratos bajos y de capas medias. El aborto se presenta como una forma de demorar el inicio del ciclo reproductivo entre mujeres de camadas medias, mientras que en estratos bajos aparece hacia el final de dicho ciclo, o para distanciar los nacimientos.

  16. “My Worries Are Rational, Climate Change Is Not”: Habitual Ecological Worrying Is an Adaptive Response

    Verplanken, Bas; Roy, Deborah

    2013-01-01

    Qualifications such as “global warming hysteria” and “energy policy schizophrenia” put forward by some climate change skeptics, usually outside the academic arena, may suggest that people who seriously worry about the environment suffer from psychological imbalance. The present study aimed to refute this thesis. While habitual worrying in general is strongly associated with psychopathological symptoms, in a survey a near-zero correlation was found between habitual ecological worrying and pathological worry. Instead, habitual ecological worrying was associated with pro-environmental attitudes and behaviors, and with a personality structure characterized by imagination and an appreciation for new ideas. The study had sufficient statistical power and measures were valid and reliable. The results confirm that those who habitually worry about the ecology are not only lacking in any psychopathology, but demonstrate a constructive and adaptive response to a serious problem. In the public domain, these findings may contribute to a more rational and less emotional debate on climate change and to the prevention of stigmatization of people who are genuinely concerned about our habitat and are prepared to do something about it (“habitual worriers are not crazy”). In the academic arena this study may contribute to environmental psychology (“habitual worrying is part of a green identity”), as well as to the literature on worry and anxiety (“habitual worrying can be a constructive response”).

    The aim of the present study was to determine the β-adrenergic contribution to sweating during incremental exercise in habitually trained males. Nine habitually trained and 11 untrained males performed incremental cycling until exhaustion (20 W/min). Bilateral forearm sweat rates (ventilated capsule) were measured at two skin sites that were transdermally administered via iontophoresis with either 1% propranolol (Propranolol, a nonselective β-adrenergic receptor antagonist) or saline (Control). The sweat rate was evaluated as a function of both relative (percentage of maximum workload) and absolute exercise intensities. The sweat rate at the Propranolol site was lower than the control during exercise at 80 (0.57 ± 0.21 and 0.45 ± 0.19 mg·cm -2 ·min -1 for Control and Propranolol, respectively) and 90% (0.74 ± 0.22 and 0.65 ± 0.17 mg·cm -2 ·min -1 , respectively) of maximum workload in trained males (all P 0.05). At the same absolute intensity, higher sweat rates on the control site were observed in trained males relative to the untrained during exercise at 160 (0.23 ± 0.20 and 0.04 ± 0.05 mg·cm -2 ·min -1 for trained and untrained, respectively) and 180 W (0.40 ± 0.20 and 0.13 ± 0.13 mg·cm -2 ·min -1 , respectively) (all P 0.05). We show that the β-adrenergic mechanism does modulate sweating during exercise at a submaximal high relative intensity in habitually trained males. The β-adrenergic mechanism may in part contribute to the greater sweat production in habitually trained males than in untrained counterparts during exercise. NEW & NOTEWORTHY We demonstrated for the first time that the β-adrenergic mechanism does modulate sweating (i.e., β-adrenergic sweating) during exercise using a localized β-adrenoceptor blockade in humans in vivo. β-Adrenergic sweating was evident in habitually trained individuals during exercise at a submaximal high relative intensity (80-90% maximal work). This observation advances

    Substance use is partially driven by habitual processes that occur automatically in response to environmental cues and may be central to users' identities. This study was designed to validate the Self-Report Habit Index (SRHI) for assessing habitual marijuana, alcohol, cigarette, and e-cigarette use. We examined the SRHI's psychometrics in separate samples of adult marijuana (Ns = 189;170), alcohol (Ns = 100;133), cigarette (Ns = 58;371), and e-cigarette (N = 239) users. A 6-item, single-factor solution evidenced good fit across substances (CFI marijuana/alcohol/cigarettes/e-cigarettes = 0.996/0.997/0.996/0.994, RMSEA = 0.046/0.047/0.067/0.068, SRMR = 0.017/0.017/0.010/0.015) and internal consistency (α = 0.88/0.94/0.95/0.91). The SRHI was scalar invariant for sex and race. However, independent-samples t-tests indicated only that women endorsed stronger habitual e-cigarette use and that men endorsed stronger habitual marijuana use. The SRHI also was scalar invariant by product type in dual-users (cigarettes/e-cigarettes[N = 371]; alcohol/cigarettes [n = 58]), although differences in habit strength only were observed for cigarettes versus e-cigarettes, with dual-users reporting stronger habitual cigarette use. Finally, the SRHI predicted frequency of marijuana, alcohol, cigarette, and e-cigarette use (n p 2 [marijuana/alcohol/cigarettes/e-cigarettes] = 0.37/0.48/0.31/0.17) and quantity of alcohol and cigarette use (n p 2  = 0.43/0.33). The SRHI is a psychometrically sound measure of adults' habitual substance use. The SRHI detected mean differences by sex and substance type and predicted the frequency of using each substance. Future research should determine if the SRHI is appropriate for use with other substances or age groups (e.g., adolescents), how it relates to task-based, behavioral measures of habit strength, and the degree to which habit predicts the development or maintenance of addiction.

    modulation is currently inconsistent. In a double-blind placebo-controlled crossover design, 18 healthy male volunteers received either placebo or a dose of 10 mg of escitalopram (SSRI), after which they were tested in both PPI and habituation of the startle reflex paradigms. No significant differences...... between the two treatments were observed on PPI, although escitalopram was found to significantly delay habituation of the ASR. In the current study, escitalopram was found to delay habituation, but it did not affect PPI in healthy male volunteers. As escitalopram is a highly specific SSRI, the results...

  1. Habituation/Fatigue behavior of a synapse memristor based on IGZO-HfO2 thin film.

    A synaptic memristor based on IGZO and oxygen-deficient HfO 2 films has been demonstrated. The memristor exhibits a fatigue response to a monotonic stimulus of voltage pulses, which is analogous to the habituation behavior of biological memory. The occurrence of habituation is nearly simultaneous with the transition from short-term memory to long-term memory. The movement and redistribution of oxygen species with the assistance of polarization in HfO 2 layer are responsible for the above results. The observation of habituation behavior proves the potential prospect of memristor on the mimic of biological neuron.

    Pothitou, Mary; Kolios, Athanasios J.; Varga, Liz; Gu, Sai

    2016-08-01

    This paper reviews existing up-to-date literature related to individual household energy consumption. The how and why individual behaviour affects energy use are discussed, together with the principles and perspectives which have so far been considered in order to explain the habitual consuming behaviour. The research gaps, which are revealed from previous studies in terms of the limitations or assumptions on the methodology to alter individuals' energy usage, give insights for a conceptual framework to define a comprehensive approach. The proposed framework suggests that the individual energy perception gaps are affected by psychological, habitual, structural and cultural variables in a wider-contextual, meso-societal and micro-individual spectrum. All these factors need to be considered in order for a variety of combined intervention methods, which are discussed and recommended, to introduce a more effective shift in the conventional energy-consuming behaviour, advancing insights for successful energy policies.

  4. Discriminación auditiva en entornos de ruido, en personas que usan auriculares de forma habitual || Perception of phonemes in noise environments, in people who usually use headphones

    Full Text Available La finalidad de este trabajo era conocer cómo la utilización diaria y prolongada de auriculares, así como el ruido de fondo, afectan a la comprensión del habla. Existe evidencia en la literatura de que el uso habitual de auriculares puede traducirse en una pérdida de audición en la frecuencia de 3000 Hz, y también son conocidas las dificultades de comprensión que surgen cuando hay un elevado nivel de ruido ambiental. Por ello, en esta investigación se quiso contar con una muestra de personas que prácticamente no han sido objeto de estudio pero que por su ocupación llevan cierto tiempo bajo los efectos de ambos factores. Así, se contó con la colaboración como grupo experimental de 24 teleoperadoras y de otras 20 personas no relacionadas con la profesión como grupo control equivalente. Para la tarea de evaluación se empleó una versión reducida y en español del Speech Perception in Noise Test. La tarea consistía en repetir la última palabra de una serie de frases pregrabadas con distintos sonidos de fondo, en las que había distintos fonemas y diferente predictibilidad de las palabras. Los resultados obtenidos mostraron que la utilización habitual de auriculares tiene un efecto negativo sobre la percepción auditiva de ciertas frecuencias y que el ruido de call center afecta negativamente a la compresión del habla, incluso más que el de tráfico. Estos hallazgos son de aplicación tanto en lo laboral como en lo educativo y prueban la importancia de sensibilizar a la población sobre el uso adecuado de auriculares.

  7. Post-training scopolamine treatment induced maladaptive behavior in open field habituation task in rats.

    Directory of Open Access Journals (Sweden)

    Natalija Popović

    Full Text Available The effects of scopolamine on memory consolidation are controversial and depend on several factors (i.e. site of administration, time of administration and testing, dose, cognitive task, experimental protocol, specie, strain, etc.. Generally, the range dose of systemic administered scopolamine, used in memory consolidation studies, has varied from 0.05 to 50 mg/kg. However, according to the literature, the most frequently used doses of scopolamine efficient on memory consolidation, are 1 and 30 mg/kg, low and high doses, respectively. In open field habituation studies only lower doses of scopolamine were used to test memory consolidation. Therefore, in the present study we compared the effects of low (1 mg/kg and high (30 mg/kg scopolamine dose, on the open field habituation task, in male Wistar rats. Scopolamine was administered immediately after the acquisition task and animals were retested 48 h later on. On the retested day, the ambulation and rearing in the open field decreased in the same manner in all tested groups. In saline- and 1 mg/kg scopolamine-treated animals, the time spent in grooming significantly decreased in the habituation task, while the same parameter significantly increased in animals treated with 30 mg/kg of scopolamine. The defecation rate significantly decreased (control group, maintained (1 mg/kg of scopolamine treated animals or significantly increased (30 mg/kg of scopolamine treated group on retention test. In conclusion, the present data suggest that post-training scopolamine administration does not affect locomotion neither exploration in the habituation to a novel environment, but increases defecation and grooming, two behaviours associated with fearful and stressful situations.

  8. Sounds scary? Lack of habituation following the presentation of novel sounds.

    Directory of Open Access Journals (Sweden)

    Tine A Biedenweg

    Full Text Available BACKGROUND: Animals typically show less habituation to biologically meaningful sounds than to novel signals. We might therefore expect that acoustic deterrents should be based on natural sounds. METHODOLOGY: We investigated responses by western grey kangaroos (Macropus fulignosus towards playback of natural sounds (alarm foot stomps and Australian raven (Corvus coronoides calls and artificial sounds (faux snake hiss and bull whip crack. We then increased rate of presentation to examine whether animals would habituate. Finally, we varied frequency of playback to investigate optimal rates of delivery. PRINCIPAL FINDINGS: Nine behaviors clustered into five Principal Components. PC factors 1 and 2 (animals alert or looking, or hopping and moving out of area accounted for 36% of variance. PC factor 3 (eating cessation, taking flight, movement out of area accounted for 13% of variance. Factors 4 and 5 (relaxing, grooming and walking; 12 and 11% of variation, respectively discontinued upon playback. The whip crack was most evocative; eating was reduced from 75% of time spent prior to playback to 6% following playback (post alarm stomp: 32%, raven call: 49%, hiss: 75%. Additionally, 24% of individuals took flight and moved out of area (50 m radius in response to the whip crack (foot stomp: 0%, raven call: 8% and 4%, hiss: 6%. Increasing rate of presentation (12x/min ×2 min caused 71% of animals to move out of the area. CONCLUSIONS/SIGNIFICANCE: The bull whip crack, an artificial sound, was as effective as the alarm stomp at eliciting aversive behaviors. Kangaroos did not fully habituate despite hearing the signal up to 20x/min. Highest rates of playback did not elicit the greatest responses, suggesting that 'more is not always better'. Ultimately, by utilizing both artificial and biological sounds, predictability may be masked or offset, so that habituation is delayed and more effective deterrents may be produced.

    To describe and compare the temporal-spatial kinematic variables of mandibular movement during deliberate unilateral and habitual mastication in healthy young-adult individuals. The study sample was composed of eight male healthy volunteers aged 19 to 24 years. The kinematic data were obtained using a motion analysis system - Qualisys Track Manager (QTM) ProReflex MCU. Recordings were performed during deliberate unilateral mastication (UM) and habitual mastication (HM) of firm-consistency gummy candy. The following variables were analyzed: (1) masticatory sequence: duration, number of masticatory cycles, and chewing rate; (2) masticatory cycle: duration, vertical and medial-lateral mandibular range of motion in relation to the skull, and maximum velocity during the opening and closing phases. Data of the variables were compared during UM and HM by the paired t test, and the effect sizes ('d' Cohen) were calculated. Regarding the variables of the masticatory sequence, smaller chewing rate was observed for UM compared with that for HM (1.19±0.21Hz and 1.29±0.16Hz, respectively, p=0.004, d=0.53). Smaller values of maximum velocity during the opening (MU=67.4 mm/s and MH=80.02, p=0.053, d=0.80) and closing (MU=71.77±9.35mm/s and MH=3.51±7mm/s, p=0.014, d=0.79) phases of the masticatory cycle were observed in deliberate unilateral mastication compared with those in habitual mastication. Kinematic variables associated with the sequence and cycle of mastication are influenced by the chewing pattern adopted - deliberate unilateral or habitual.

  10. Habituation contributes to the decline in wheel running within wheel-running reinforcement periods.

    Habituation appears to play a role in the decline in wheel running within an interval. Aoyama and McSweeney [Aoyama, K., McSweeney, F.K., 2001. Habituation contributes to within-session changes in free wheel running. J. Exp. Anal. Behav. 76, 289-302] showed that when a novel stimulus was presented during a 30-min interval, wheel-running rates following the stimulus increased to levels approximating those earlier in the interval. The present study sought to assess the role of habituation in the decline in running that occurs over a briefer interval. In two experiments, rats responded on fixed-interval 30-s schedules for the opportunity to run for 45 s. Forty reinforcers were completed in each session. In the first experiment, the brake and chamber lights were repeatedly activated and inactivated after 25 s of a reinforcement interval had elapsed to assess the effect on running within the remaining 20 s. Presentations of the brake/light stimulus occurred during nine randomly determined reinforcement intervals in a session. In the second experiment, a 110 dB tone was emitted after 25 s of the reinforcement interval. In both experiments, presentation of the stimulus produced an immediate decline in running that dissipated over sessions. No increase in running following the stimulus was observed in the first experiment until the stimulus-induced decline dissipated. In the second experiment, increases in running were observed following the tone in the first session as well as when data were averaged over several sessions. In general, the results concur with the assertion that habituation plays a role in the decline in wheel running that occurs within both long and short intervals. (c) 2004 Elsevier B.V.

    Barefoot locomotion is widely believed to be beneficial for motor development and biomechanics but are implied to be responsible for foot pathologies and running-related injuries. Although most of available studies focused on acute effects of barefoot running and walking little is known regarding the effects of long-term barefoot versus shod locomotion. The purpose of this study was to systematically review the literature to evaluate current evidence of habitual barefoot (HB) versus habitual shod locomotion on foot anthropometrics, biomechanics, motor performance, and pathologies. Four electronic databases were searched using terms related to habitually barefoot locomotion. Relevant studies were identified based on title, abstract, and full text, and a forward (citation tracking) and backward (references) search was performed. Risk of bias was assessed, data pooling, and meta-analysis (random effects model) performed and finally levels of evidence determined. Fifteen studies with 8399 participants were included. Limited evidence was found for a reduced ankle dorsiflexion at footstrike (pooled effect size, -3.47; 95% confidence interval [CI], -5.18 to -1.76) and a lower pedobarographically measured hallux angle (-1.16; 95% CI, -1.64 to -0.68). HB populations had wider (0.55; 95% CI, 0.06-1.05) but no shorter (-0.22; 95% CI, -0.51 to 0.08) feet compared with habitual shod populations. No differences in relative injury rates were found, with limited evidence for a different body part distribution of musculoskeletal injuries and more foot pathologies and less foot deformities and defects in HB runners. Only limited or very limited evidence is found for long-term effects of HB locomotion regarding biomechanics or health-related outcomes. Moreover, no evidence exists for motor performance. Future research should include prospective study designs.

    Health-related quality of life (HRQL) is a global indicator of perceived health status, which includes physical and mental domains. Several biological mechanisms might support an association between consumption of yogurt and better HRQL. Our aim was to assess the association between habitual yogurt consumption and HRQL in the general adult population. We conducted a prospective study with 4,445 individuals aged 18 years and older who were recruited in 2008 to 2010 and were followed up to 2012. Habitual yogurt consumption was assessed at baseline with a validated diet history. HRQL was measured with the Physical Composite Summary and the Mental Composite Summary of the Spanish version of the SF-12 Health Survey. The analysis of the association between baseline yogurt consumption and HRQL at 2012 was performed with linear regression and adjusted for the main confounders, including baseline HRQL. Mean follow-up was 3.5 years (standard deviation=0.6 years). Compared with nonconsumers of yogurt, the Physical Composite Summary scores were similar in habitual consumers of ≤6 servings/week (β=.40; P=0.20) and in consumers of ≥1 serving/day (β=.25; P=0.45). A suggestion of tendency toward a lower Mental Composite Summary score was found among daily yogurt consumers (β=-.65; P=0.09; P for trend across categories=0.07). Results were similar among individuals without morbidity, never smokers, and individuals with higher adherence to the Mediterranean diet. Habitual yogurt consumption did not show an association with improved HRQL. Copyright © 2015 Academy of Nutrition and Dietetics. Published by Elsevier Inc. All rights reserved.

    Breakfast has been shown to be beneficial for cognitive and academic performance in school children. However, there is a paucity of studies which examine the relationship between breakfast consumption and academic performance and a complete absence of studies in UK school children. The aim of this study, therefore, was to examine the association between habitual breakfast consumption frequency and Cognitive Abilities Test (CAT) performance, a reasoning test routinely used in UK schools. Adolescents aged 11-13 years (n = 292; males: 53.8%) completed a questionnaire to report usual weekly breakfast intake frequency. Breakfast was subjectively defined by the participants. Habitual weekly breakfast consumption frequency was categorized as rare (0-2 days), occasional (3-4 days), or frequent (5-7 days). Participants' CAT performance was used as a proxy measure of academic performance. The CAT has three components: verbal, non-verbal, and quantitative reasoning. Normative standard age scores (SAS) for verbal, non-verbal, quantitative reasoning, and overall mean SAS were obtained from school records and hierarchical linear regression models were applied, adjusting for the confounders: gender, ethnicity, socio-economic status, English as an Additional Language, and body mass index. Habitual breakfast consumption frequency did not significantly predict any CAT SAS in all models (crude and adjusted). However, methodological considerations which could account for this disagreement with previous research, were identified. These included the isolation of school-day breakfast consumption, use of a standard definition of breakfast, and measurement of actual academic performance.

    Intake of added sugars, mainly fructose and sucrose, has been associated with risk factors for cognitive impairment, such as obesity, the metabolic syndrome and type 2 diabetes. The objective of this analysis was to examine whether habitual intakes of total sugars, added sugars, sugar-sweetened beverages or sweetened solid foods are associated with cognitive function. The present study included 737 participants without diabetes, aged 45–75 years, from the Boston Puerto Rican Health Study, 200...

    Full Text Available Breakfast has been shown to be beneficial for cognitive and academic performance in school children. However, there is a paucity of studies which examine the relationship between breakfast consumption and academic performance and a complete absence of studies in UK school children. The aim of this study, therefore, was to examine the association between habitual breakfast consumption frequency and Cognitive Abilities Test (CAT performance, a reasoning test routinely used in UK schools. Adolescents aged 11-13 years (n=292; males: 53.8% completed a questionnaire to report usual weekly breakfast intake frequency. Breakfast was subjectively defined by the participants. Habitual weekly breakfast consumption frequency was categorized as rare (0-2 days, occasional (3-4 days or frequent (5-7 days. Participants’ CAT performance was used as a proxy measure of academic performance. The CAT has three components: verbal, non-verbal and quantitative reasoning. Normative standard age scores (SAS for verbal, nonverbal, quantitative reasoning and overall mean SAS were obtained from school records and hierarchical linear regression models were applied, adjusting for the confounders: gender, ethnicity, socio-economic status, English as an Additional Language and body mass index. Habitual breakfast consumption frequency did not significantly predict any CAT SAS in all models (crude and adjusted. However, methodological considerations which could account for this disagreement with previous research were identified. These included the isolation of school-day breakfast consumption, use of a standard definition of breakfast, and measurement of actual academic performance. The findings of the current study suggest more comprehensive ways in which future studies might investigate the relationship between habitual breakfast consumption and academic performance.

    Studies suggest that exaggerated amygdala reactivity is a vulnerability factor for posttraumatic stress disorder (PTSD); however, our understanding is limited by a paucity of prospective, longitudinal studies. Recent studies in healthy samples indicate that, relative to reactivity, habituation is a more reliable biomarker of individual differences in amygdala function. We investigated reactivity of the amygdala and cortical areas to repeated threat presentations in a prospective study of PTSD. Participants were recruited from the emergency department of a large level I trauma center within 24 hours of trauma. PTSD symptoms were assessed at baseline and approximately 1, 3, 6, and 12 months after trauma. Growth curve modeling was used to estimate symptom recovery trajectories. Thirty-one individuals participated in functional magnetic resonance imaging around the 1-month assessment, passively viewing fearful and neutral face stimuli. Reactivity (fearful > neutral) and habituation to fearful faces was examined. Amygdala reactivity, but not habituation, 5 to 12 weeks after trauma was positively associated with the PTSD symptom intercept and predicted symptoms at 12 months after trauma. Habituation in the ventral anterior cingulate cortex was positively associated with the slope of PTSD symptoms, such that decreases in ventral anterior cingulate cortex activation over repeated presentations of fearful stimuli predicted increasing symptoms. Findings point to neural signatures of risk for maintaining PTSD symptoms after trauma exposure. Specifically, chronic symptoms were predicted by amygdala hyperreactivity, and poor recovery was predicted by a failure to maintain ventral anterior cingulate cortex activation in response to fearful stimuli. The importance of identifying patients at risk after trauma exposure is discussed. Copyright © 2017 Society of Biological Psychiatry. Published by Elsevier Inc. All rights reserved.

    Sleep need differs between individuals, and so the same duration of sleep will lead to sleep insufficiency in some individuals but not others. The aim of this study was to determine the separate and combined associations of both sleep duration and unmet sleep need with excessive daytime sleepiness (EDS) in Korean adults. The participants comprised 2,769 Korean adults aged 19 years or older. They completed questionnaires about their sleep habits over the previous month. The question regarding sleep need was "How much sleep do you need to be at your best during the day?" Unmet sleep need was calculated as sleep need minus habitual sleep duration. Participants with a score of >10 on the Epworth Sleepiness Scale were considered to have EDS. The overall prevalence of EDS was 11.9%. Approximately one-third of the participants (31.9%) reported not getting at least 7 hours of sleep. An unmet sleep need of >0 hours was present in 30.2% of the participants. An adjusted multivariate logistic regression analysis revealed a significant excess risk of EDS in the groups with unmet sleep needs of ≥2 hours [odds ratio (OR), 1.80; 95% confidence interval (CI), 1.27-2.54] and 0.01-2 hours (OR, 1.42; 95% CI, 1.02-1.98). However, habitual sleep duration was not significantly related to EDS. EDS was found to be associated with unmet sleep need but not with habitual sleep duration when both factors were examined together. We suggest that individual unmet sleep need is more important than habitual sleep duration in terms of the relation to EDS.

    For the neurophysiological examination of nociceptive pathways, contact-heat evoked potentials (contact-heat EPs) are elicited by repetitive brief noxious heat stimuli. Suppression of heat responses in primary nociceptive neurons during repetitive stimulation has been shown in animal models in vivo and in vitro. We now investigated whether heat pain and contact-heat EPs in humans display equivalent signs of habituation. Heat pain and EPs were elicited in 16 volunteers with a contact thermode (30 degrees Cs(-1)). Heat pulses at three intensities (pain threshold, moderate noxious and maximum available) were applied to the right forearm either by moving the thermode after each pulse to variable locations or when fixed to one location (inter-stimulus intervals 8-10s). Contact-heat EPs consisted of an early negativity in temporal leads (N1), followed by a biphasic response at the vertex (N2-P2). Pain ratings and contact-heat EPs (N1 and N2-P2 components) displayed significant temperature dependence. N2-P2 correlated positively with ratings. With stimulation at variable locations, both measures slowly decreased with time constants tau of 2 min (ratings) and 12 min (EPs). With stimulation at a fixed location, habituation was much faster for both, ratings (tau=10s) and EPs (tau=33 s). As a consequence, both measures were significantly reduced (pheat pain perception and contact-heat EPs display signs of rapid habituation when stimulation is restricted to a fixed location and thus, reflect fatigue of peripheral nociceptive neurons. Habituation within the central nervous system is slower and less pronounced.

  6. Problemas derivados de la indeterminación legal de la profesión habitual: situaciones de compatibilidad no deseadas y propuestas de revisión

    Directory of Open Access Journals (Sweden)

    Ana Álvarez Moreno

    Full Text Available La determinación de la profesión habitual se configura como una de las piezas clave del sistema por el que se rige la declaración de invalidez permanente. Lo es porque determina tanto la procedencia de la declaración inicial de la invalidez, de manera fundamental en la incapacidad permanente total, como la compatibilidad de la misma una vez reconocida con el trabajo, con un salario o con una posible prestación futura derivada del mismo. La indeterminación legal de los parámetros que configuran el reconocimiento de una situación de invalidez deriva, en situaciones de compatibilidad difíciles de justificar. Sin duda la más sorprendente es la prácticamente absoluta compatibilidad de la situación de incapacidad permanente absoluta y de gran invalidez con el trabajo, según la doctrina configurada por el Tribunal Supremo. También hay dificultad para revisar el grado de incapacidad reconocido, puesto que la misma ha de ajustarse a los motivos tasados por el legislador. Conclusiones: - Delimitar el concepto de profesión habitual de una forma de manera que se amplíe desde el marco reducido de las funciones al más amplio del grupo profesional o, cuando menos, al que habilita al empresario para efectuar la movilidad funcional. - Modificar las actuales causas de revisión de la invalidez posibilitando que la mejoría también pueda ser considerada desde la perspectiva profesional, bien por la adaptación y rehabilitación funcional posterior o bien porque las modificaciones de los procesos productivos modifiquen la capacidad profesional inicialmente determinada. - Determinar en supuestos de nuevo trabajo si es compatible con las limitaciones funcionales objetivadas e impedir así el desempeño de trabajos con requerimientos similares o superiores a los que provocaron el reconocimiento de la situación de IPT. - Suspender la pensión de IPT en el supuesto de que el beneficiario de la misma simultaneé su percibo con el desempeño de la misma

  7. Not all mice are equal: welfare implications of behavioural habituation profiles in four 129 mouse substrains.

    Directory of Open Access Journals (Sweden)

    Hetty Boleij

    Full Text Available Safeguarding the welfare of animals is an important aim when defining housing and management standards in animal based, experimental research. While such standards are usually defined per animal species, it is known that considerable differences between laboratory mouse strains exist, for example with regard to their emotional traits. Following earlier experiments, in which we found that 129P3 mice show a lack of habituation of anxiety related behaviour after repeated exposure to an initially novel environment (non-adaptive profile, we here investigated four other 129 inbred mouse substrains (129S2/SvPas, 129S2/SvHsd (exp 1; 129P2 and 129X1 (exp 2 on habituation of anxiety related behaviour. Male mice of each strain were repeatedly placed in the modified hole board test, measuring anxiety-related behaviour, exploratory and locomotor behaviour. The results reveal that all four substrains show a lack of habituation behaviour throughout the period of testing. Although not in all of the substrains a possible confounding effect of general activity can be excluded, our findings suggest that the genetic background of the 129 substrains may increase their vulnerability to cope with environmental challenges, such as exposure to novelty. This vulnerability might negatively affect the welfare of these mice under standard laboratory conditions when compared with other strains. Based on our findings we suggest to consider (substrain-specific guidelines and protocols, taking the (substrain-specific adaptive capabilities into account.

    The aim of the study was to determine whether habitual minimalist shoe runners present with purported favorable running biomechanithat reduce running injury risk such as initial loading rate. Eighteen minimalist and 16 traditionally cushioned shod runners were assessed when running both in their preferred training shoe and barefoot. Ankle and knee joint kinetics and kinematics, initial rate of loading, and footstrike angle were measured. Sagittal ankle and knee joint stiffness were also calculated. Results of a two-factor ANOVA presented no group difference in initial rate of loading when participants were running either shod or barefoot; however, initial loading rate increased for both groups when running barefoot (p=0.008). Differences in footstrike angle were observed between groups when running shod, but not when barefoot (minimalist:8.71±8.99 vs. traditional: 17.32±11.48 degrees, p=0.002). Lower ankle joint stiffness was found in both groups when running barefoot (p=0.025). These findings illustrate that risk factors for injury potentially differ between the two groups. Shoe construction differences do change mechanical demands, however, once habituated to the demands of a given shoe condition, certain acute favorable or unfavorable responses may be moderated. The purported benefits of minimalist running shoes in mimicking habitual barefoot running is questioned, and risk of injury may not be attenuated. © Georg Thieme Verlag KG Stuttgart · New York.

    To examine the associations of TV viewing time and domain-specific physical activity with weight change; to determine whether domain-specific physical activity moderates the potential association of TV viewing time with weight change. We used four-year longitudinal data (baseline: 2003-2004, follow-up: 2007-2008) on 969 adults from selected neighborhoods in Adelaide, Australia (Age: 48.6 ± 10.6 years, 61% females). Mixed models examined four-year weight change as the dependent variable, with TV viewing time, habitual transport and past week domain-specific physical activity at baseline as independent variables. On average, participants gained 1.6 kg over four years. TV viewing time at baseline was positively associated with weight gain at follow-up. Each additional hour of TV viewing was associated with 0.24-0.27 kg of extra weight gain. This relationship was not moderated by recent recall of transport, leisure-time, and occupational physical activity, but was moderated by habitual transport: an additional hour of TV viewing time at baseline was significantly associated with an extra weight gain of 0.65 kg at follow-up among those who were inactive in everyday transport; TV time was not significantly associated with weight change among those who were regularly active in transport. Habitual active transport may protect adults against risk of weight gain associated with prolonged TV viewing time. Copyright © 2012 Elsevier Inc. All rights reserved.

  10. Measurement of habituation to noise using the method of continuous judgment by category

    Using "the method of continuous judgment by category", we examined the noisiness of sounds from public loudspeakers, and habituation to them. Subjects judged the noisiness of the sound at any moment of their choice by touching one of seven numbered keys on a computer keyboard, each corresponding to a noisiness category. At the same time, the subjects were required to complete a task as carefully and rapidly as possible. The duration of "no response" to sounds was an index of habituation. Both personality factors and physical factors were analyzed. It was found that the duration of "no response" is a good index to habituation to noise, and that there were wide differences in the "no response" time of different subjects. The reactions of individual subjects in sessions 1 and 2 and the questionnaire survey were, however, consistent. This suggests that there is a group that is relatively sensitive to noise and a group that is less sensitive to noise. It was also found that subjects had difficulty in becoming accustomed to intense noise.

    Children with autism spectrum disorder (ASD) exhibit difficulties processing and encoding sensory information in daily life. Cognitive response to environmental change in control individuals is naturally dynamic, meaning it habituates or reduces over time as one becomes accustomed to the deviance. The origin of atypical response to deviance in ASD may relate to differences in this dynamic habituation. The current study of 133 children and young adults with and without ASD examined classic electrophysiological responses (MMN and P3a), as well as temporal patterns of habituation (i.e., N1 and P3a change over time) in response to a passive auditory oddball task. Individuals with ASD showed an overall heightened sensitivity to change as exhibited by greater P3a amplitude to novel sounds. Moreover, youth with ASD showed dynamic ERP differences, including slower attenuation of the N1 response to infrequent tones and the P3a response to novel sounds. Dynamic ERP responses were related to parent ratings of auditory sensory-seeking behaviors, but not general cognition. As the first large-scale study to characterize temporal dynamics of auditory ERPs in ASD, our results provide compelling evidence that heightened response to auditory deviance in ASD is largely driven by early sensitivity and prolonged processing of auditory deviance.

    Full Text Available Habituation of the orienting response has long served as a model system for studying fundamental psychological phenomena such as learning, attention, decisions and surprise. In this article, we review an emerging hypothesis that the evolutionary role of the superior colliculus (SC in mammals or its homologue in birds, the optic tectum (OT, is to select the most salient target and send this information to the appropriate brain regions to control the body and brain orienting responses. Recent studies have begun to reveal mechanisms of how saliency is computed in the OT/SC, demonstrating a striking similarity between mammals and birds. The saliency of a target can be determined by how different it is from the surrounding objects, by how different it is from its history (that is habituation and by how relevant it is for the task at hand. Here, we will first review evidence, mostly from primates and barn owls, that all three types of saliency computations are linked in the OT/SC. We will then focus more on neural adaptation in the OT and its possible link to temporal saliency and habituation.

    The aim of ths study was to examine the association between habitual physical activity and positive and negative affect. This cross-sectional study included 276 women aged 20 +, from the Geelong Osteoporosis Study. Habitual physical activity and other lifestyle exposures were assessed by questionnaire, concurrent with anthropometric assessments. Physical activity was categorized as very active, moderately active or sedentary. Positive and negative affect scores were derived from the validated 20 item Positive and Negative Affect Schedule (PANAS) self-report and were categorized into tertiles. There was a pattern of lower positive affect scores for lower levels of physical activity. With very active as the reference category, the odds for having a positive affect score in the highest tertile were sequentially lower for those who were moderately active (OR = 0.53, 95%CI 0.28-1.01) and sedentary (OR = 0.28, 95%CI 0.10-0.75). Associations were sustained after adjusting for body mass index and polypharmacy (OR = 0.50, 95%CI 0.26-0.96 and OR = 0.25, 95%CI 0.09-0.72, respectively). These associations were not explained by age, negative affect score or other exposures. No association was detected between physical activity and negative affect scores. This study reports that higher positive affect scores, encompassing emotions such as interest, excitement, enthusiasm and alertness, are associated with higher levels of habitual physical activity. These observations warrant further investigations into possible mechanistic interplay between neurobiological and psychosocial factors that underpin this association.

    Familiarity with stimuli that bring neither reward nor punishment, manifested through behavioural habituation, enables organisms to detect novelty and devote cognition to important elements of the environment. Here we describe in mice a form of long-term behavioural habituation to visual grating stimuli that is selective for stimulus orientation. Orientation-selective habituation (OSH) can be observed both in exploratory behaviour in an open arena, and in a stereotyped motor response to visual stimuli in head-restrained mice. We show that the latter behavioural response, termed a vidget, requires V1. Parallel electrophysiological recordings in V1 reveal that plasticity, in the form of stimulus-selective response potentiation (SRP), occurs in layer 4 of V1 as OSH develops. Local manipulations of V1 that prevent and reverse electrophysiological modifications likewise prevent and reverse memory demonstrated behaviourally. These findings suggest that a form of long-term visual recognition memory is stored via synaptic plasticity in primary sensory cortex. PMID:25599221

    In a previous publication [Deacon RMJ, Cholerton LL, Talbot K, Nair-Roberts RG, Sanderson DJ, Romberg C, et al. Age-dependent and -independent behavioral deficits in Tg2576 mice. Behav Brain Res 2008;189:126-38] we found that very few cognitive tests were suitable for demonstrating deficits in Tg2576 mice, an amyloid over-expression model of Alzheimer's disease, even at 23 months of age. However, in a retrospective analysis of a separate project on these mice, tests of social memory and open field habituation revealed large cognitive impairments. Controls showed good open field habituation, but Tg2576 mice were hyperactive and failed to habituate. In the test of social memory for a juvenile mouse, controls showed considerably less social investigation on the second meeting, indicating memory of the juvenile, whereas Tg2576 mice did not show this decrement.As a control for olfactory sensitivity, on which social memory relies, the ability to find a food pellet hidden under wood chip bedding was assessed. Tg2576 mice found the pellet as quickly as controls. As this test requires digging ability, this was independently assessed in tests of burrowing and directly observed digging. In line with previous results and the hippocampal dysfunction characteristic of aged Tg2576 mice, they both burrowed and dug less than controls.

    This study assessed changes in selected physiological and kinematic variables over 6 weeks of treadmill skating in an effort to understand the process of habituation to this novel training modality. Seven male, Atom-A hockey players who were injury-free and had no previous treadmill skating experience participated in the study. Players performed four 1-min skating bouts at progressively increasing speeds, each week, for 6 weeks. One speed (10.5 km/h) was repeated weekly to allow for assessment of the habituation process. Our criteria for habituation were: a decrease in stride rate, heart rate and rating of perceived exertion, and an increase in stride length, trunk angle and vertical movement of the centre of mass, leading to a plateau, over the course of the 6-week study. Significant decreases were seen in stride rate, heart rate and ratings of perceived exertion, and significant increases were found in stride length. Some of these changes were evident after only one week of training and all were present by week 4. After 6 weeks (24 min) of exposure to treadmill skating, all participants displayed a visibly more efficient skating style.

    Full Text Available Social and economic changes occurring in the last two decades in Mozambique may have induced lifestyle changes among youth. This study aimed to document secular changes in habitual physical activities of Mozambican youth between 1992, 1999 and 2012. A total of 3393 youth (eight–15 years, were measured in three different time periods (1992, 1999, 2012. Habitual physical activity (PA was estimated with a questionnaire, including items related to household chores, sport participation, traditional games and walking activities. Biological maturation was assessed. Analysis of Covariance (ANCOVA was used to compare mean differences in PA across the years. Significant decreases between 1992–1999 and 1992–2012 were observed for boys in household chores, games and walking, and a significant decline between 1999 and 2012 was found in sport participation. Among girls, a significant and consistent decline (1992 > 1999 > 2012 was observed for household chores, a decline between 1992–1999 and 1992–2012 for games and walking, and a significant increase between 1992 and 1999 in sport participation. In general, a negative secular trend was found in habitual PA among Mozambican youth. Interventions aimed at increasing PA represent important educational and public health opportunities.

    Considerable behavioral data indicates that operant actions can become habitual, as evidenced by insensitivity to changes in the action-outcome contingency and in subjective outcome values. Notably, although several studies have investigated the neural substrates of habits, none has clearly differentiated the areas of the human brain that support habit formation from those that implement habitual control. We scanned participants with fMRI as they learned and performed an operant task in which the conditional structure of the environment encouraged either goal-directed encoding of the consequences of actions, or a habit-like mapping of actions to antecedent cues. Participants were also scanned during a subsequent assessment of insensitivity to outcome devaluation. We identified dissociable roles of the cerebellum and ventral striatum, across learning and test performance, in behavioral insensitivity to outcome devaluation. We also show that the inferior parietal lobule – an area previously implicated in several aspects of goal-directed action selection, including the attribution of intent and awareness of agency – predicts sensitivity to outcome devaluation. Finally, we reveal a potential functional homology between the human subgenual cortex and rodent infralimbic cortex in the implementation of habitual control. In summary, our findings suggest a broad systems division, at the cortical and subcortical levels, between brain areas mediating the encoding and expression of action-outcome and stimulus-response associations.

    Men have been frequently found to perform more accurately than women in mental rotation tasks. However, men and women also differ with regard to the habitual use of emotion regulation strategies, particularly with regard to expressive suppression, i.e., the suppression of emotional expression in behavior. As emotional suppression is more often used by men, emotion regulation strategies might be a variable modulating gender differences in mental rotation performance. The present study, therefore, examined the influences of gender and emotion regulation strategies on mental rotation performance accuracy and feedback processing. Twenty-eight men and 28 women matched for relevant demographic variables performed mental rotation tasks of varying difficulty over a prolonged time. Emotional feedback was given immediately after each trial. Results showed that women reported to use expressive suppression less frequently than men. Women made more errors in the mental rotation task than men confirming earlier demonstrations of gender differences. Furthermore, women were more impaired by the negative feedback as indicated by the increased likelihood of subsequent errors compared with men. Task performance of women not habitually using expressive suppression was most inferior and most strongly influenced by failure feedback compared with men. Women using expressive suppression more habitually did not significantly differ in mental rotation accuracy and feedback processing from men. Hence, expressive suppression reduces gender differences in mental rotation accuracy by improving cognitive performance following failure feedback.

    There are associations described between dementia, mild cognitive impairment (MCI) and foods with a high content of polyphenols. To assess the infl uence of habitual chocolate consumption over the MMSE in Spanish older adults. Cross-sectional study, using data of the follow-up of the Seniors-Study on Nutrition and Cardiovascular Risk in Spain (ENRICA) cohort. Habitual chocolate consumption in the last year was assessed with a computerized dietary history; differences between dark chocolate and milk chocolate were recorded. Chocolate intake was classified into the following categories: no consumption, chocolate consumption of ≥ 10 g/d had a better MMSE score (adjusted beta coefficient and 95% confidence interval: 0.26 (0.02-0.50; p trend = 0.05); for dark chocolate, the results were also statistically significant (0.48 [0.18-0.78]; p trend chocolate consumption was not associated with higher likelihood of having MCI. However, dark chocolate consumption was associated with less likelihood of MCI (OR and 95%CI for MMSE ≤ 25: 0.39 [0.20-0.77]; for MMSE ≤ 24: 0.26 [0.10-0.67]; and for MMSE ≤ 23: 0.25 [0.07-0.82]). Our results suggest that habitual dark chocolate consumption might improve cognitive function among the older population.

    Self-induced hypoxia has been reported particularly in adolescents, and it can result in neurological injury. Here, we present a case of electroencephalogram (EEG) abnormalities induced by habitual neck compression differentiated from epileptic seizures by Tc-99m HMPAO SPECT. A 19-year-old male was admitted for evaluation of recurrent generalized tonic-clonic seizures. No interictal EEG abnormality was detected; however, abnormal slow delta waves were found immediately after habitual right neck compression. To differentiate EEG abnormalities due to a hemodynamic deficit induced by habitual neck compression from an epileptic seizure, Tc-99m HMPAO SPECT was performed immediately after right carotid artery compression. Abnormal delta waves were triggered, and cerebral hypoperfusion in the right internal carotid artery territory was detected on Tc-99m HMPAO SPECT. The slow delta wave detected on the EEG resulted from the cerebral hypoperfusion because of the habitual neck compression.

    Full Text Available RESUMO: Poincianella pyramidalis (catingueira é uma planta tóxica associada a abortos, perdas embrionárias e malformações em caprinos e animais de laboratório. Surtos e casos esporádicos de intoxicação espontânea em ovinos vem sendo relatados nos últimos cinco anos no agreste de Pernambuco. Devido à ocorrência destes casos espontâneos e a escassez de pesquisas na espécie ovina, o objetivo desse trabalho foi realizar um estudo experimental para avaliação dos efeitos teratogênicos de P. pyramidalis em ovelhas. No experimento foram utilizadas 16 ovelhas e três carneiros, sem raça definida (SRD. As fêmeas foram divididas em quatro grupos, com quatro animais por grupo e mantidas em baias individuais, foram submetidas a sincronização do estro e acasalamento por monta natural, após 30 dias foi realizado o diagnóstico para confirmação da gestação.

    The preorbital gland plays not only an olfactory role in cervids but also a visual one. Opening this gland is an easy way for the calf to communicate with the mother, indicating hunger/satiety, stress, pain, fear, or excitement. This information can be also useful for farm operators to assess how fast the calves habituate to handling routines and to detect those calves that do not habituate and may suffer chronic stress in the future. Thirty-one calves were subjected to 2 consecutive experiments to clarify if observing preorbital gland opening is related to habituation to handling in red deer calves (Cervus elaphus). Calves were born in 3 different paddocks, handled as newborns (Exp. 1), and then subjected to the same routine handling but with different periodicity: every 1, 2, or 3 wk (Exp. 2). In Exp. 1, preorbital gland opening was recorded in newborns during an initial handling (including weighing, ear tagging, and sex determination). Preorbital gland opening occurred in 93% of calves during this procedure and was not affected by sex, time since birth, or birth weight. Experiment 2 consisted of measuring preorbital opening during the same routine handling (weighing, blood sampling, and rump touching to assess body condition) when calves were 1, 3, and 5 mo old. Binary logistic regression showed that gland opening was associated with habituation to handling, since at 1 and 3 mo the probability of opening the gland decreased with the number of handlings that a calf experienced before (P = 0.008 and P = 0.028, respectively). However, there were no further changes in preorbital gland opening rate in the 5-mo-old calves (P = 0.182). The significant influence of the number of previous handlings on the probability of opening the preorbital gland was confirmed through generalized linear model with repeated measures (P = 0.007). Preorbital gland opening decreased along the phases of the study. Nevertheless, we found a significant trend in individuals to keep similar

    Reduced time in bed relative to biological sleep need is common. The impact of habitual short sleep on auditory attention has not been studied to date. In the current study, we utilized novelty oddball tasks to evaluate the effect of habitual short sleep on brain function underlying attention control processes measured by the mismatch negativity (MMN, index of pre-attentive stage), P3a (attention-dependent), and P3b (memory-dependent) event related brain potentials (ERPs). An extended time in bed in a separate study was used to evaluate the possible reversal of the impairments of these processes in habitual short sleepers. Ten self-defined short sleepers (total sleep time [TST] ≤ 6 h) and 9 normal-sleeping subjects with TST 7-8 h, participated. ERPs were recorded via a 64-channel EEG system. Two test conditions: "ignore" and "attend" were implemented. The ERPs were analyzed and compared between groups on the 2 task conditions and frontal/central/parietal electrodes by 3-factor ANOVA. Sleep diary data were compared between groups by t-test. Sleep was recorded by the Zeo sleep monitoring system for a week in both habitual and extended sleep conditions at home. The main findings of the present study show that short sleeping individuals had deficiency in activity of the MMN and P3a brain responses over frontal areas compared to normal-sleeping subjects. The P3b amplitude was increased over frontal areas and decreased over parietal with respect to the control group. Extension of time in bed for one week increased TST (from 5.7 h to 7.4 h), and concomitantly MMN amplitude increased from -0.1 μV up to -1.25 μV over frontal areas. Reduced time in bed is associated with deficiency of the neuronal process associated with change detection, which may recover after one week of sleep extension, whereas attention-dependent neural processes do not normalize after this period of time in habitually short sleeping individuals and may require longer recovery periods.

    Full Text Available The present article is aimed at examining the category of the reality status by discussing the dichotomy “realis / irrealis” in the context of the categories of modality, habituality and futurity. Prototype analysis is juxtaposed with scope analysis, and the category of the habitual is discussed from the typological perspective as well as from the perspective of its connection with the category of futurity. The paper presents aspect diversity of habituals (perfective and imperfective aspect and its contextual implications as well as the differentiation between the habitual and modality. A special focus is on the prototype analysis and its application instances in Polish, English and Hebrew. The primary objective of the paper is to show that, although it is possible to treat irrealis as notional category, the habituals in Polish and many other Slavic languages (e.g. Czech should be identified with the modality domain rather than irrealis category. The paper is also an attempt to provide an insight into the distinction between (irrealis and encoding systems of modalities as the habitual aspect displays modal category features in many languages (including Polish.

    Principal component analysis (PCA) is a widely used exploratory method in epidemiology to derive dietary patterns from habitual diet. Such dietary patterns seem to originate from intakes on multiple days and eating occasions. Therefore, analyzing food intake of study populations with different levels of food consumption can provide additional insights as to how habitual dietary patterns are formed. We analyzed the food intake data of German adults in terms of the relations among food groups from three 24-h dietary recalls (24hDRs) on the habitual, single-day, and main-meal levels, and investigated the contribution of each level to the formation of PCA-derived habitual dietary patterns. Three 24hDRs were collected in 2010-2012 from 816 adults for an European Prospective Investigation into Cancer and Nutrition (EPIC)-Potsdam subcohort study. We identified PCA-derived habitual dietary patterns and compared cross-sectional food consumption data in terms of correlation (Spearman), consistency (intraclass correlation coefficient), and frequency of consumption across all days and main meals. Contribution to the formation of the dietary patterns was obtained through Spearman correlation of the dietary pattern scores. Among the meals, breakfast appeared to be the most consistent eating occasion within individuals. Dinner showed the strongest correlations with "Prudent" (Spearman correlation = 0.60), "Western" (Spearman correlation = 0.59), and "Traditional" (Spearman correlation = 0.60) dietary patterns identified on the habitual level, and lunch showed the strongest correlations with the "Cereals and legumes" (Spearman correlation = 0.60) habitual dietary pattern. Higher meal consistency was related to lower contributions to the formation of PCA-derived habitual dietary patterns. Absolute amounts of food consumption did not strongly conform to the habitual dietary patterns by meals, suggesting that these patterns are formed by complex combinations of variable food

    Full Text Available The increase of ecotourism operations within Costa Rica during the last 20yrs has brought more and more humans into close, direct contact with several wildlife species. One of these species is the white-faced capuchin (Cebus capucinus, highly gregarious, and with exposure over time, willing to come into close vicinity of humans and their developments. Such contact has its advantages and disadvantages for the ecotourism industry. We observed white-faced monkeys in order to assess the impact of human presence and development on monkey behavior, with a focus on aggressive, affiliative, and foraging behaviors in Curú Wildlife Refuge (CWR, located in Puntarenas, Costa Rica, and to ascertain the degree of over-habituation of capuchin populations at CWR. Though there exists no discrete behavioral parameters that measure over-habituation, it can be defined as an extreme state of habituation in which non-human primates not only lose fear of humans, but also actively include humans in social interactions or treat them as a food resource. We used instantaneous focal animal and group scan sampling during 8wks in March and April 2012. Two groups (approximately 20-30 individuals each of capuchins were observed; the first near the tourist development at the Southwestern area of CWR, representing a habituated population that regularly foraged, rested, and groomed in the presence of humans. The second, was observed in the Northeastern area of CWR, did not visit the center of human activity and exhibited fear of humans. The habituated group exhibited significantly fewer instances of threatened behavior in response to human presence (p<0.0001 than the non-habituated group, and spent significantly more time eating and foraging (p<0.0001. While the habituated monkeys at CWR may not be over-habituated, they could become that way as development, especially ecotourism, increases. Over-habituation is a problem that affects capuchins in certain ecotourism sites in Costa

MÉTODOS: Se utilizó método cualitativo, realizándose entrevistas en profundidad, grupos focales y observación participativa. Los tópicos indagados fueron aspectos socioculturales, sexualidad, reproducción y aspectos de salud en relación al aborto. Se entrevistó en profundidad a 9 parteras y se realizó un grupo focal en el que participaron 16 parteras. RESULTADOS: Éstos dan cuenta de una profunda actitud de rechazo ante el aborto, inducido o espontáneo. El primero se conceptúa como un pecado grave y el segundo como un fracaso en la principal función de la mujer en estas comunidades, la reproducción. Las mujeres que abortan son llamadas "puercas", "cochinas" o "perras" y las parteras se muestran reacias a atenderlas. Sin embargo, es común entre las mujeres de la comunidad la práctica de la "regulación de la regla", es decir, la utilización de sustancias que hacen que aparezca la menstruación si ésta se ha retrasado. Dicha práctica no se considera abortiva. CONCLUSIONES: El conocimiento del mundo de significaciones populares en torno al aborto es imprescindible para construir modelos y estrategias efectivas que, desde los servicios institucionales de salud, refuercen los vínculos entre éstos y las parteras tradicionales, de manera que se mejore el acceso a servicios y la calidad de la atención a las mujeres.OBJETIVO: Conhecer a percepção, recursos e práticas que as parteiras tradicionais, de uma área rural mexicana, possuem sobre o aborto.

    Extreme emotional reactivity is a defining feature of borderline personality disorder, yet the neural-behavioral mechanisms underlying this affective instability are poorly understood. One possible contributor is diminished ability to engage the mechanism of emotional habituation. The authors tested this hypothesis by examining behavioral and neural correlates of habituation in borderline patients, healthy comparison subjects, and a psychopathological comparison group of patients with avoidant personality disorder. During fMRI scanning, borderline patients, healthy subjects, and avoidant personality disorder patients viewed novel and repeated pictures, providing valence ratings at each presentation. Statistical parametric maps of the contrasts of activation during repeated versus novel negative picture viewing were compared between groups. Psychophysiological interaction analysis was employed to examine functional connectivity differences between groups. Unlike healthy subjects, neither borderline nor avoidant personality disorder patients exhibited increased activity in the dorsal anterior cingulate cortex when viewing repeated versus novel pictures. This lack of an increase in dorsal anterior cingulate activity was associated with greater affective instability in borderline patients. In addition, borderline and avoidant patients exhibited smaller increases in insula-amygdala functional connectivity than healthy subjects and, unlike healthy subjects, did not show habituation in ratings of the emotional intensity of the images. Borderline patients differed from avoidant patients in insula-ventral anterior cingulate functional connectivity during habituation. Unlike healthy subjects, borderline patients fail to habituate to negative pictures, and they differ from both healthy subjects and avoidant patients in neural activity during habituation. A failure to effectively engage emotional habituation processes may contribute to affective instability in borderline

    Parkour is an activity that encompasses methods of jumping, climbing and vaulting. With landing being a pertinent part of this practise, Parkour participants (traceurs) have devised their own habitual landing strategies, which are suggested to be a safer and more effective style of landing. The purpose of this study was to compare the habitual landing strategies of traceurs and recreationally trained individuals from differing drop heights. Comparisons between landing sound and mechanical parameters were also assessed to gauge the level of landing safety. Ten recreationally trained participants and ten traceurs performed three landings from 25% and 50% body height using their own habitual landing strategies. Results at 25% showed significantly lower maximal vertical force (39.9%, p strike analysis revealed traceurs landed using forefoot or forefoot-midfoot strategies in 93.2% of trials; whereas recreationally trained participants used these styles in only 8.3% of these landings. To conclude, the habitual landings of traceurs are more effective at lowering the kinetic landing variables associated with a higher injury risk in comparison to recreationally trained individuals. Sound as a measure of landing effectiveness and safety holds potential significance; however requires further research to confirm. Key pointsHabitual traceur landings were observed to be safer landing techniques in comparison to those utilised by recreationally trained individuals, due to the lower maximal vertical forces, slower times to maximal vertical force, lesser loading rates and lower maximal sound.Traceurs predominantly landed with the forefoot only, whereas recreationally trained individuals habitually utilised a forefoot to heel landing strategy.The habitual landing techniques performed by traceurs may be beneficial for other landing sports to incorporate into training to reduce injury.

    The increase of ecotourism operations within Costa Rica during the last 20 yrs has brought more and more humans into close, direct contact with several wildlife species. One of these species is the white-faced capuchin (Cebus capucinos), highly gregarious, and with exposure over time, willing to come into close vicinity of humans and their developments. Such contact has its advantages and disadvantages for the ecotourism industry. We observed white-faced monkeys in order to assess the impact of human presence and development on monkey behavior, with a focus on aggressive, affiliative, and foraging behaviors in Curú Wildlife Refuge (CWR), located in Puntarenas, Costa Rica, and to ascertain the degree of over-habituation of capuchin popula- tions at CWR.

The second, was observed in the Northeastern area of CWR, did not visit the center of human activity and exhibited fear of humans. The habituated group exhibited significantly fewer instances of threatened behavior in response to human presence (p ecotourism, increases. Over-habituation is a problem that affects capuchins in certain ecotourism sites in Costa Rica. It is critical that the consequences of habituation be studied more carefully, primarily in areas where ecotourism operations draw visitors to wildlife habitats.

    Behavior therapy is effective for Persistent Tic Disorders (PTDs), but behavioral processes facilitating tic reduction are not well understood. One process, habituation, is thought to create tic reduction through decreases in premonitory urge severity. The current study tested whether premonitory urges decreased in youth with PTDs (N = 126) and adults with PTDs (N = 122) who participated in parallel randomized clinical trials comparing behavior therapy to psychoeducation and supportive therapy (PST). Trends in premonitory urges, tic severity, and treatment outcome were analyzed according to the predictions of a habituation model, whereby urge severity would be expected to decrease in those who responded to behavior therapy. Although adults who responded to behavior therapy showed a significant trend of declining premonitory urge severity across treatment, results failed to demonstrate that behavior therapy specifically caused changes in premonitory urge severity. In addition, reductions in premonitory urge severity in those who responded to behavior therapy were significant greater than those who did not respond to behavior therapy but no different than those who responded or did not respond to PST. Children with PTDs failed to show any significant changes in premonitory urges. Reductions in premonitory urge severity did not mediate the relationship between treatment and outcome in either adults or children. These results cast doubt on the notion that habituation is the therapeutic process underlying the effectiveness of behavior therapy, which has immediate implications for the psychoeducation and therapeutic rationale presented in clinical practice. Moreover, there may be important developmental changes in premonitory urges in PTDs, and alternative models of therapeutic change warrant investigation. Copyright © 2017. Published by Elsevier Ltd.

    Regular physical activity is generally associated with psychological well-being, although there are relatively few prospective studies in older adults. We investigated habitual physical activity as a risk factor for de novo depressive and anxiety disorders in older men and women from the general population. In this nested case-control study, subjects aged 60 years or more were identified from randomly selected cohorts being followed prospectively in the Geelong Osteoporosis Study. Cases were individuals with incident depressive or anxiety disorders, diagnosed using the Structured Clinical Interview for DSM-IV-TR (SCID-I/NP); controls had no history of these disorders. Habitual physical activity, measured using a validated questionnaire, and other exposures were documented at baseline, approximately four years prior to psychiatric interviews. Those with depressive or anxiety disorders that pre-dated baseline were excluded. Of 547 eligible subjects, 14 developed de novo depressive or anxiety disorders and were classified as cases; 533 controls remained free of disease. Physical activity was protective against the likelihood of depressive and anxiety disorders; OR = 0.55 (95% CI 0.32-0.94), p = 0.03; each standard deviation increase in the transformed physical activity score was associated with an approximate halving in the likelihood of developing depressive or anxiety disorders. Leisure-time physical activity contributed substantially to the overall physical activity score. Age, gender, smoking, alcohol consumption, weight and socioeconomic status did not substantially confound the association. This study provides evidence consistent with the notion that higher levels of habitual physical activity are protective against the subsequent risk of development of de novo depressive and anxiety disorders.

    Accidental immersion in cold water is a risk factor for many occupations. Habituation to cold-water immersion (CWI) is one practical means of reducing the cold shock response (CSR) on immersion. We investigated whether repeated thermoneutral water immersion (TWI) induced a perceptual habituation (i.e., could lessen perceived threat and anxiety) and consequently reduce the CSR on subsequent CWI. There were 12 subjects who completed seven 7-min head-out immersions. Immersions one and seven were CWls [15.0 (0.1) degrees C], and immersions two to six were TWI [34.9 (0.10) degrees C]. Anxiety 120-cm visual analogue scale) and the cardiorespiratory responses [heart rate (f(C)), respiratory frequency (f(R)), tidal volume (V(T)), and minute ventilation (V(E))] to immersion were measured throughout. Data were compared within subject between conditions using ANOVA to an alpha level of 0.05. Acute anxiety was significantly reduced after repeated exposure to the immersion scenario (i.e., TWI): CWI-1: 6.3 (4.4) cm; and CWI-2: 4.5 (4.0) cm [condition mean (SD)]. These differences did not influence the peak in the CSR. The f(C), f(R), and V(E) responses were similar between CWI-1 and CWI-2. V(T) response was significantly lower in CWI-2; mean (SD) across the immersion: CWI-1 1.27 (0.17) vs. CWI-2 1.11 0.21 L. Repeated TWI lessened the anxiety associated with CWI (perceptual habituation). This had a negligible effect on the primary components of the CSR, but did lower VT, which may reduce the volume of any aspirated water in an emergency situation. Reducing the threat appraisal of an environmental stressor may be a useful biproduct of survival training, thereby minimizing psychophysiological strain.

    The loss of the conscious control of respiration on whole body cold water immersion (CWI) can result in the aspiration of water and drowning. Repeated CWI reduces the respiratory drive evoked by CWI and should prolong breath-hold time on CWI (BHmax(CWI)). Psychological skills training (PST) can also increase BHmax(CWI) by improving the ability of individuals to consciously suppress the drive to breathe. This study tested the hypothesis that combining PST and repeated CWI would extend BHmax(CWI) beyond that seen following only repeated CWI. There were 20 male subjects who completed two 2.5-min, head-out breath-hold CWI (BH1 and BH2) in water at 12 degrees C. Following BH1, subjects were matched on BHmax(CWI) and allocated to a habituation (HAB) group or a habituation plus PST group (H+PST). Between BH1 and BH2 both experimental groups undertook five 2.5-min CWI on separate days, during which they breathed freely. The H+PST also received psychological training to help tolerate cold and suppress the drive to breathe on immersion to extend BHmax(CWI). During BH1, mean BHmax(CWI) (+/- SD) in the HAB group was 22.00 (10.33) s and 22.38 (10.65) s in the H+PST. After the five free-breathing CWI, both groups had a longer BHmax(CWI) in BH2. The HAB group improved by 14.13 (20.21) s, an increase of 73%. H+PST improved by 26.86 (24.70) s, a 120% increase. No significant differences were identified between the groups. Habituation significantly increases BHmax on CWI, the addition of PST did not result in statistically significant improvements in BHmax(CWI), but may have practical significance.

  14. Speed/accuracy trade-off between the habitual and the goal-directed processes.

    Full Text Available Instrumental responses are hypothesized to be of two kinds: habitual and goal-directed, mediated by the sensorimotor and the associative cortico-basal ganglia circuits, respectively. The existence of the two heterogeneous associative learning mechanisms can be hypothesized to arise from the comparative advantages that they have at different stages of learning. In this paper, we assume that the goal-directed system is behaviourally flexible, but slow in choice selection. The habitual system, in contrast, is fast in responding, but inflexible in adapting its behavioural strategy to new conditions. Based on these assumptions and using the computational theory of reinforcement learning, we propose a normative model for arbitration between the two processes that makes an approximately optimal balance between search-time and accuracy in decision making. Behaviourally, the model can explain experimental evidence on behavioural sensitivity to outcome at the early stages of learning, but insensitivity at the later stages. It also explains that when two choices with equal incentive values are available concurrently, the behaviour remains outcome-sensitive, even after extensive training. Moreover, the model can explain choice reaction time variations during the course of learning, as well as the experimental observation that as the number of choices increases, the reaction time also increases. Neurobiologically, by assuming that phasic and tonic activities of midbrain dopamine neurons carry the reward prediction error and the average reward signals used by the model, respectively, the model predicts that whereas phasic dopamine indirectly affects behaviour through reinforcing stimulus-response associations, tonic dopamine can directly affect behaviour through manipulating the competition between the habitual and the goal-directed systems and thus, affect reaction time.

    Full Text Available Este artigo analisa a polêmica em torno da determinação dos limites da vida, a partir do pressuposto de que a demarcação das fronteiras entre vida e morte envolve questões culturais, sociais, religiosas e políticas referentes à gestão da pessoa. Debates acerca do aborto e da eutanásia evidenciam concepções morais sobre os direitos individuais que, por sua vez, são passíveis de normatização em cada contexto. Tais temas revelam para além da criação e do desenvolvimento de novas tecnologias médicas, direcionadas à reprodução assistida, medicina fetal e manutenção artificial da vida, seja de prematuros ou de doentes fora de possibilidades de cura valores e posicionamentos, muitas vezes contrastivos. A partir de levantamento de projetos de lei apresentados no âmbito legislativo brasileiro, constatou-se a presença de discursos opostos, oriundos da religião e de defensores da autonomia individual, o que ilustra os dilemas contemporâneos sobre os limites da vida.This article analyzes the controversy surrounding what can be established as the limit of life, from the presumption that the frontier marks between life and death involve cultural, social, religious and political issues referred to personhood management. Debates about abortion and euthanasia make it clear that moral concepts on individual rights can be standardized in each context. These themes reveal beyond new medical technology creation and development, focused on assisted fertilization, fetal medicine and maintaining life artificially, either for premature babies or patients without possibilities of cure values and viewpoints, often opposed. From the survey of law projects, presented within Brazilian legislative field, opposite positions were revealed, from religion and defenders of individual autonomy, which illustrates the contemporary dilemmas on the limits of life.

Fragile X Syndrome (FXS) is a leading genetic cause of intellectual disability and autism. Electrophysiological responses in humans with FXS show reduced habituation with sound repetition and this deficit may underlie auditory hypersensitivity in FXS. Our previous study in Fmr1 knockout (KO) mice revealed an unusually long state of increased sound-driven excitability in auditory cortical neurons suggesting that cortical responses to repeated sounds may exhibit abnormal habituation as in humans with FXS. Here, we tested this prediction by comparing cortical event related potentials (ERP) recorded from wildtype (WT) and Fmr1 KO mice. We report a repetition-rate dependent reduction in habituation of N1 amplitude in Fmr1 KO mice and show that matrix metalloproteinase-9 (MMP-9), one of the known FMRP targets, contributes to the reduced ERP habituation. Our studies demonstrate a significant up-regulation of MMP-9 levels in the auditory cortex of adult Fmr1 KO mice, whereas a genetic deletion of Mmp-9 reverses ERP habituation deficits in Fmr1 KO mice. Although the N1 amplitude of Mmp-9/Fmr1 DKO recordings was larger than WT and KO recordings, the habituation of ERPs in Mmp-9/Fmr1 DKO mice is similar to WT mice implicating MMP-9 as a potential target for reversing sensory processing deficits in FXS. Together these data establish ERP habituation as a translation relevant, physiological pre-clinical marker of auditory processing deficits in FXS and suggest that abnormal MMP-9 regulation is a mechanism underlying auditory hypersensitivity in FXS. Fragile X Syndrome (FXS) is the leading known genetic cause of autism spectrum disorders. Individuals with FXS show symptoms of auditory hypersensitivity. These symptoms may arise due to sustained neural responses to repeated sounds, but the underlying mechanisms remain unclear. For the first time, this study shows deficits

    Casi la generalidad de los estudios realizados sobre cementos con adición de cenizas volantes se refieren a sus características y comportamiento en pastas, morteros y hormigones, siempre en relación con aquéllos del cemento portland. Esta vez, se desarrolló un trabajo experimental orientado a relacionar entre sí los cementos con adiciones de cenizas volantes y de puzolana natural. Para ello se fabricaron a escala de laboratorio cementos de ambos tipos, empleando como materias primas comunes clinker y yeso y, como variables, diferentes porcentajes de las dos adiciones, que cumplieron previamente los requisitos normalizados en cuanto a sus actividades puzolánicas. La calidad de los cementos fabricados resultó adecuada y concordante con la del cemento portland-puzolánico obtenido a escala industrial con los mismos clinker, yeso y puzolana natural de este estudio. Posteriormente, se determinaron las características de los cementos experimentales y se confeccionaron morteros normales para la realización de ensayos físicos y mecánicos. Los resultados de ensayos indicaron que los cementos con adición de cenizas volantes (CCV requieren menos agua para consistencia normal, presentan tiempos de fraguado mayores y expansiones en autoclave menores que los cementos con adición de puzolana (CP. Los calores de hidratación a 7 y 28 días de edad fueron aproximadamente similares para ambos tipos de cemento. En morteros normales, los cementos CCV mostraron menor retracción de secado, mayor retentividad y mayor fluidez (para igual cantidad de agua que los cementos CP. En los ensayos de exudación se observó que ésta depende más de la finura que el tipo de adición. Finalmente, los ensayos mecánicos señalaron que las resistencias a compresión y flexotracción de los morteros con cementos CCV son menores a edades inferiores que 14 días (del orden de 5 a 10% a un día de edad, pero que a partir de entonces pasan a ser mayores que las de

    Increased anthropogenic activity can result in parasite exchanges and/or general changes in parasite communities, imposing a health risk to great apes. We studied protist and helminth parasites of wild western lowland gorilla groups in different levels of habituation, alongside humans inhabiting Dzanga-Sangha Protected Areas in the Central African Republic. Faeces were collected yearly during November and December from 2007 to 2010 and monthly from November 2010 to October 2011. Protist and helminth infections were compared among gorilla groups habituated, under habituation and unhabituated, and the effect of host traits and seasonality was evaluated. Zoonotic potential of parasites found in humans was assessed. No significant differences in clinically important parasites among the groups in different stages of habituation were found, except for Entamoeba spp. However, humans were infected with four taxa which may overlap with taxa found in gorillas. Females were less infected with spirurids, and adults had higher intensities of infection of Mammomonogamus sp. We found seasonal differences in the prevalence of several parasite taxa, but most importantly, the intensity of infection of unidentified strongylids was higher in the dry season. This study highlights that habituation may not necessarily pose a greater risk of protist and helminth infections in gorilla groups.

  5. Habituation of the orienting reflex and the development of Preliminary Process Theory.

    Barry, Robert J

    2009-09-01

    The orienting reflex (OR), elicited by an innocuous stimulus, can be regarded as a model of the organism's interaction with its environment, and has been described as the unit of attentional processing. A major determinant of the OR is the novelty of the eliciting stimulus, generally operationalized in terms of its reduction with stimulus repetition, the effects of which are commonly described in habituation terms. This paper provides an overview of a research programme, spanning more than 30 years, investigating psychophysiological aspects of the OR in humans. The major complication in this research is that the numerous physiological measures used as dependent variables in the OR context fail to jointly covary with stimulus parameters. This has led to the development of the Preliminary Process Theory (PPT) of the OR to accommodate the complexity of the observed stimulus-response patterns. PPT is largely grounded in autonomic measures, and current work is attempting to integrate electroencephalographic measures, particularly components in the event-related brain potentials reflecting aspects of stimulus processing. The emphasis in the current presentation is on the use of the defining criteria of the habituation phenomenon, and Groves and Thompson's Dual-process Theory, in the development of PPT.

    Although soft drinks are heavily advertised, widely consumed, and have been associated with obesity, little is understood regarding neural responsivity to soft drink intake, anticipated intake, and advertisements. Functional MRI was used to assess examine neural response to carbonated soft drink intake, anticipated intake and advertisement exposure as well as milkshake intake in 27 adolescents that varied on soft drink consumer status. Intake and anticipated intake of carbonated Coke® activated regions implicated in gustatory, oral somatosensory, and reward processing, yet high-fat/sugar milkshake intake elicited greater activation in these regions vs. Coke intake. Advertisements highlighting the Coke product vs. nonfood control advertisements, but not the Coke logo, activated gustatory and visual brain regions. Habitual Coke consumers vs. nonconsumers showed greater posterior cingulate responsivity to Coke logo ads, suggesting that the logo is a conditioned cue. Coke consumers exhibited less ventrolateral prefrontal cortex responsivity during anticipated Coke intake relative to nonconsumers. Results indicate that soft drinks activate reward and gustatory regions, but are less potent in activating these regions than high-fat/sugar beverages, and imply that habitual soft drink intake promotes hyper-responsivity of regions encoding salience/attention toward brand specific cues and hypo-responsivity of inhibitory regions while anticipating intake.

    Full Text Available Eminectomy which is one of the popular and most effective treatments for habitual temporomandibular joint luxation was first described by Myrhaug in 1951. There are few reports which described eminectomy being performed under local anesthesia and conscious sedation. We present a case series of habitual luxation of the TMJ treated by eminectomy performed under local anesthesia and conscious sedation and general anesthesia. Five patients were examined and found to have recurrent luxation of the TMJ. The age of patients ranged from 18 to 93 years. Bilateral eminectomy of the TMJ was performed for two patients, and unilateral eminectomy was performed for three patients. Two were examined under intravenous propofol sedation and local anesthesia, while three patients were examined under general anesthesia. One patient died from ileus one month after surgery. The follow-up period except for the case that died from ileus ranged from 12 to 33 months. No recurrent dislocation of the TMJ has been identified. Based on our experience and two other series in the literature, eminectomy with sedation and local anesthesia can be considered and might be a good option in elderly patients.

    Background The consumption of chocolate and cocoa has established cardiovascular benefits. Less is known about the effects of chocolate on arterial stiffness, a marker of subclinical cardiovascular disease. The aim of this study was to investigate whether chocolate intakes are independently associated with pulse wave velocity (PWV), after adjustment for cardiovascular, lifestyle and dietary factors. Methods Prospective analyses were undertaken on 508 community-dwelling participants (mean age 61 years, 60% women) from the Maine-Syracuse Longitudinal Study (MSLS). Habitual chocolate intakes, measured using a food frequency questionnaire, were related to PWV, measured approximately 5 years later. Results Chocolate intake was significantly associated with PWV in a non-linear fashion with the highest levels of PWV in those who never or rarely ate chocolate and lowest levels in those who consumed chocolate once a week. This pattern of results remained and was not attenuated after multivariate adjustment for diabetes, cardiovascular risk factors and dietary variables (p = 0.002). Conclusions Weekly chocolate intake may be of benefit to arterial stiffness. Further studies are needed to explore the underlying mechanisms that may mediate the observed effects of habitual chocolate consumption on arterial stiffness. PMID:27493901

    The purpose of this study was to describe caffeine use among a group of habitual caffeine users, truck drivers, and to explore the associations between caffeine use and critical safety events by age in the naturalistic work setting. A secondary analysis of existing data from the Naturalistic Truck Driving Study was conducted. Analyses focused on the association between sleep and caffeine consumption by duty status, comparisons of sleep and caffeine use by age, and the associations between caffeine use and safety-critical events (SCEs). Findings indicated differences in caffeine use by duty status. However, no difference in sleep time by duty status, or between sleep time and caffeine use was found regardless of when the caffeine was consumed during the 5 hours prior to sleep. Sleep time did not vary significantly by age, although increasing age was associated with decreased caffeine use. Overall, a 6% reduction in the rate of SCEs per eight ounces of caffeinated beverage consumed was found. This study makes a unique scientific contribution because it uses real-time observations of truckers in the naturalistic work setting. It also does not involve caffeine withdrawal but rather an investigation of the effects of the naturalistic consumption of caffeine on sleep and driving performance. Findings suggest that caffeine use among habitual users offers a protective effect for safety-critical driving events. Occupational health nurses may use this information to counsel workers in the use of caffeine to enhance driving safety. © 2015 The Author(s).

    Background and aims The current study examined the mediating role of maladaptive perfectionism among parental psychological control, eating disorder symptoms, and exercise dependence symptoms by gender in habitual exercisers. Methods Participants were 348 Italian exercisers (n = 178 men and n = 170 women; M age = 20.57, SD = 1.13) who completed self-report questionnaires assessing their parental psychological control, maladaptive perfectionism, eating disorder symptoms, and exercise dependence symptoms. Results Results of the present study confirmed the mediating role of maladaptive perfectionism for eating disorder and exercise dependence symptoms for the male and female exercisers in the maternal data. In the paternal data, maladaptive perfectionism mediated the relationships between paternal psychological control and eating disorder and exercise dependence symptoms as full mediator for female participants and as partial mediator for male participants. Discussion Findings of the present study suggest that it may be beneficial to consider dimensions of maladaptive perfectionism and parental psychological control when studying eating disorder and exercise dependence symptoms in habitual exerciser.

  13. Music and Video Gaming during Breaks: Influence on Habitual versus Goal-Directed Decision Making.

    Full Text Available Different systems for habitual versus goal-directed control are thought to underlie human decision-making. Working memory is known to shape these decision-making systems and their interplay, and is known to support goal-directed decision making even under stress. Here, we investigated if and how decision systems are differentially influenced by breaks filled with diverse everyday life activities known to modulate working memory performance. We used a within-subject design where young adults listened to music and played a video game during breaks interleaved with trials of a sequential two-step Markov decision task, designed to assess habitual as well as goal-directed decision making. Based on a neurocomputational model of task performance, we observed that for individuals with a rather limited working memory capacity video gaming as compared to music reduced reliance on the goal-directed decision-making system, while a rather large working memory capacity prevented such a decline. Our findings suggest differential effects of everyday activities on key decision-making processes.

    Full Text Available Recent studies have shown that instructed cognitive reappraisal can regulate the neural processing of reward. However, it is still unclear whether the habitual use of cognitive reappraisal in everyday life can influence brain activity associated with reward processing. In the present study, participant’s neural responses to reward were measured using electroencephalography (EEG recorded during a gambling task, while their tendency to use cognitive reappraisal was assessed using the Emotion Regulation Questionnaire (ERQ. Event-related potential (ERP results indicated that losses on the gambling task elicited greater negative reward-related feedback negativity (FN than gains. The differential FN between losses and gains was significantly correlated with cognitive reappraisal scores across participants, such that individuals with a higher tendency to use cognitive reappraisal showed stronger reward processing (i.e. amplified FN difference between losses and gains. This correlation remained significant after controlling for expressive suppression scores. However, expressive suppression per se was not correlated with FN differences. Taken together, these results suggest that the habitual use of cognitive reappraisal influences the neural processing of reward.

    CT findings of the head in 120 chronic alcoholics aged 30 to 69 yrs. were compared with those of 93 controls matched in age. The patient group showed a definitely higher incidence of dilatation of the brain surface and the ventricular system. The dilatation in the patients had no preferred site, both the brain surface and ventricular system being affected in most cases. In the patients no constant relation was noted between CT findings and the presence or absence of withdrawal symptoms, intellectual impairement, hepatic dysfunction or malnutrition. CT abnormality was not always reflected on EEG in the patients. The reversibility of abnormal CT could not be confirmed. CT findings of habitual drinkers (35 subjects in their 50s) living with no social or familial trouble were compared with those of non-drinkers (35 subjects in the same generation). The incidence of dilatation of various regions and the frequency of such cases in the habitual drinkers were definitely higher than those of the non-drinkers.

    Underlying psychophysiological mechanisms of effect linking openness to experience to health outcomes, and particularly cardiovascular well-being, are unknown. This study examined the role of openness in the context of cardiovascular responsivity to acute psychological stress. Continuous cardiovascular response data were collected for 74 healthy young female adults across an experimental protocol, including differing counterbalanced acute stressors. Openness was measured via self-report questionnaire. Analysis of covariance revealed openness was associated with systolic blood pressure (SBP; p = .016), and diastolic blood pressure (DBP; p = .036) responsivity across the protocol. Openness was also associated with heart rate (HR) responding to the initial stress exposure (p = .044). Examination of cardiovascular adaptation revealed that higher openness was associated with significant SBP (p = .001), DBP (p = .009), and HR (p = .002) habituation in response to the second differing acute stress exposure. Taken together, the findings suggest persons higher in openness are characterized by an adaptive cardiovascular stress response profile within the context of changing acute stress exposures. This study is also the first to demonstrate individual differences in cardiovascular adaptation across a protocol consisting of differing stress exposures. More broadly, this research also suggests that future research may benefit from conceptualizing an adaptive fitness of openness within the context of change. In summary, the present study provides evidence that higher openness stimulates short-term stress responsivity, while ensuring cardiovascular habituation to change in stress across time. © 2017 Society for Psychophysiological Research.

    Runners tend to shift from a rearfoot to a forefoot strike pattern when running barefoot. However, it is unclear how the first attempts at running barefoot affect habitually rearfoot shod runners. Due to the inconsistency of their recently adopted barefoot technique, a number of new barefoot-related running injuries are emerging among novice barefoot runners. The aim of this study was therefore to analyse the influence of three running conditions (natural barefoot [BF], barefoot with a forced rearfoot strike [BRS], and shod [SH]) on muscle activity and impact accelerations in habitually rearfoot shod runners. Twenty-two participants ran at 60% of their maximal aerobic speed while foot strike, tibial and head impact accelerations, and tibialis anterior (TA), peroneus longus (PL), gastrocnemius medialis (GM) and gastrocnemius lateralis (GL) muscle activity were registered. Only 68% of the runners adopted a non-rearfoot strike pattern during BF. Running BF led to a reduction of TA activity as well as to an increase of GL and GM activity compared to BRS and SH. Furthermore, BRS increased tibial peak acceleration, tibial magnitude and tibial acceleration rate compared to SH and BF. In conclusion, 32% of our runners showed a rearfoot strike pattern at the first attempts at running barefoot, which corresponds to a running style (BRS) that led to increased muscle activation and impact accelerations and thereby to a potentially higher risk of injury compared to running shod.

    Oral cancer incidence of 77,003 poses a major health concern in India, with 5-10 % tobacco habitués developing oral cancer. The current study examined the role of specific genomic variants in oral cancer. We examined five genomic variants represented as single nucleotide polymorphisms (SNPs) in genes associated with cell proliferation and cellular invasion. The SNPs rs2124437 (RASGRP3), rs1335022 (GRIK2), rs4512367 (PREX2), rs4748011 (CCDC3), and rs1435218 (LNX1) were analyzed in 500 histopathologically confirmed oral cancers and 500 healthy controls with a minimum of 10 years of tobacco usage. Allelic discrimination real-time PCR SYBR Green assay was used. The genotypic and allelic frequencies between cases and controls were analyzed using SPSS software (version 19) and odds ratio (OR) using Hutchon.net, indicating increased risk to oral cancers. A significant association of the SNPs in oral cancer was observed in RASGRP3 AA (rs2124437) (p oral cancer in tobacco habitués.

    Our objective was to evaluate the association between habitual daytime napping and the prevalence of metabolic syndrome. We conducted a population-based study of 8,547 subjects aged 40 years or older. Metabolic syndrome was defined according to a harmonized definition from a joint statement and the recommended thresholds for the Chinese population. Information about sleep duration was self-reported. The prevalence of metabolic syndrome in the no daytime napping group, the 0 to 1 hour daytime napping group and the more than 1 hour daytime napping group were 35.0%, 36.0% and 44.5% among the females (Pnapping hours were positively associated with parameters of metabolic syndrome in the female subjects, including waist circumference, systolic blood pressure, triglycerides and fasting plasma glucose (Pnapping females, napping for more than 1 hour was independently associated with an increased prevalence of metabolic syndrome (odds ratio 1.39, 95% confidence interval, 1.13-1.72). Compared to the female subjects in the no daytime napping group, those habitually napped for more than 1 hour exhibited 46% and 26% increases in the prevalence of central obesity and hypertriglyceridemia (all Pnapping hours and metabolic syndrome among the male subjects.

    Full Text Available Rats implanted bilaterally with cannulae in the CA1 region of the dorsal hippocampus or the entorhinal cortex were submitted to either a one-trial inhibitory avoidance task, or to 5 min of habituation to an open field. Immediately after training, they received intrahippocampal or intraentorhinal 0.5-µl infusions of saline, of a vehicle (2% dimethylsulfoxide in saline, of the glutamatergic N-methyl-D-aspartate (NMDA receptor antagonist 2-amino-5-phosphono pentanoic acid (AP5, of the protein kinase A inhibitor Rp-cAMPs (0.5 µg/side, of the calcium-calmodulin protein kinase II inhibitor KN-62, of the dopaminergic D1 antagonist SCH23390, or of the mitogen-activated protein kinase kinase inhibitor PD098059. Animals were tested in each task 24 h after training. Intrahippocampal KN-62 was amnestic for habituation; none of the other treatments had any effect on the retention of this task. In contrast, all of them strongly affected memory of the avoidance task. Intrahippocampal Rp-cAMPs, KN-62 and AP5, and intraentorhinal Rp-cAMPs, KN-62, PD098059 and SCH23390 caused retrograde amnesia. In view of the known actions of the treatments used, the present findings point to important biochemical differences in memory consolidation processes of the two tasks.

    Nutritional epidemiology is increasingly shifting its focus from studying single nutrients to the exploration of the whole diet utilizing dietary pattern analysis. We analyzed associations between habitual diet (including macronutrients, dietary patterns, biomarker of fish intake) and lipoprotein particle subclass profile in young adults. Complete dietary data (food-frequency questionnaire) and lipoprotein subclass profile (via nuclear magnetic resonance spectroscopy) were available for 663 subjects from the population-based FinnTwin12 study (57% women, age: 21-25 y). The serum docosahexaenoic to total fatty acid ratio was used as a biomarker of habitual fish consumption. Factor analysis identified 5 dietary patterns: "Fruit and vegetables", "Meat", "Sweets and desserts", "Junk food" and "Fish". After adjustment for sex, age, body mass index, waist circumference, physical activity, smoking status and alcohol intake, the "Junk food" pattern was positively related to serum triglycerides (r = 0.12, P = 0.002), a shift in the subclass distribution of VLDL toward larger particles (r = 0.12 for VLDL size, P consumption is related to favorable subclass distributions of VLDL and HDL, while junk food intake is associated with unfavorable alterations in the distribution of all lipoprotein subclasses independent of adiposity and other lifestyle factors.

    Nicotine is a psychoactive substance that is commonly consumed in the context of music. However, the reason why music and nicotine are co-consumed is uncertain. One possibility is that nicotine affects cognitive processes relevant to aspects of music appreciation in a beneficial way. Here we investigated this possibility using Event-Related Potentials. Participants underwent a simple decision-making task (to maintain attentional focus), responses to which were signalled by auditory stimuli. Unlike previous research looking at the effects of nicotine on auditory processing, we used complex tones that varied in pitch, a fundamental element of music. In addition, unlike most other studies, we tested non-smoking subjects to avoid withdrawal-related complications. We found that nicotine (4.0 mg, administered as gum) increased P2 amplitude in the frontal region. Since a decrease in P2 amplitude and latency is related to habituation processes, and an enhanced ability to disengage from irrelevant stimuli, our findings suggest that nicotine may cause a reduction in habituation, resulting in non-smokers being less able to adapt to repeated stimuli. A corollary of that decrease in adaptation may be that nicotine extends the temporal window during which a listener is able and willing to engage with a piece of music.

  4. "An army of reformed drunkards and clergymen": the medicalization of habitual drunkenness, 1857-1910.

    2014-07-01

    Historians have recognized that men with drinking problems were not simply the passive subjects of medical reform and urban social control in Gilded Age and Progressive Era America but also actively shaped the partial medicalization of habitual drunkenness. The role played by evangelical religion in constituting their agency and in the historical process of medicalization has not been adequately explored, however. A post-Civil War evangelical reform culture supported institutions that treated inebriates along voluntary, religious lines and lionized former drunkards who publicly promoted a spiritual cure for habitual drunkenness. This article documents the historical development and characteristic practices of this reform culture, the voluntarist treatment institutions associated with it, and the hostile reaction that developed among medical reformers who sought to treat intemperance as a disease called inebriety. Those physicians' attempts to promote therapeutic coercion for inebriates as medical orthodoxy and to deprive voluntarist institutions of public recognition failed, as did their efforts to characterize reformed drunkards who endorsed voluntary cures as suffering from delusions arising from their disease. Instead, evangelical traditions continued to empower reformed drunkards to publicize their own views on their malady which laid the groundwork for continued public interest in alcoholics' personal narratives in the twentieth century. Meanwhile, institutions that accommodated inebriates' voluntarist preferences proliferated after 1890, marginalizing the medical inebriety movement and its coercive therapeutics. © The Author 2013.

    Full Text Available Whole-life beer consumption and a quantitative measurement of several dietary micronutrients consumed in adult life were obtained from the dietary and alcohol data of the case-control arm of the population-based Melbourne Colorectal Cancer Study. There was a statistically significant risk, adjusted for other established risk factors, among habitual beer drinkers (AOR 1.75, 95% CI 1.28–2.41 with a significant positive dose-response effect (AOR trend 1.34, 95% CI 1.16–1.55. Among beer consumers the data were interpreted as showing an attenuation of this risk with consumption of the four micronutrients involved in methylation: folate, methionine, vitamins B6 and B12, and the four micronutrients examined with antioxidant properties: selenium, vitamins E, C, and lycopene. The strongest effects were noted with vitamins E, C, and lycopene, and the weakest with methionine and selenium. Whilst not condoning excessive beer drinking, the regular consumption of foods rich in these micronutrients may provide a simple and harmless preventative strategy among persistent habitual beer drinkers and deserves further study with larger study numbers.

    Humans have engaged in endurance running for millions of years, but the modern running shoe was not invented until the 1970s. For most of human evolutionary history, runners were either barefoot or wore minimal footwear such as sandals or moccasins with smaller heels and little cushioning relative to modern running shoes. We wondered how runners coped with the impact caused by the foot colliding with the ground before the invention of the modern shoe. Here we show that habitually barefoot endurance runners often land on the fore-foot (fore-foot strike) before bringing down the heel, but they sometimes land with a flat foot (mid-foot strike) or, less often, on the heel (rear-foot strike). In contrast, habitually shod runners mostly rear-foot strike, facilitated by the elevated and cushioned heel of the modern running shoe. Kinematic and kinetic analyses show that even on hard surfaces, barefoot runners who fore-foot strike generate smaller collision forces than shod rear-foot strikers. This difference results primarily from a more plantarflexed foot at landing and more ankle compliance during impact, decreasing the effective mass of the body that collides with the ground. Fore-foot- and mid-foot-strike gaits were probably more common when humans ran barefoot or in minimal shoes, and may protect the feet and lower limbs from some of the impact-related injuries now experienced by a high percentage of runners.

    Full Text Available The eating habits formation of the individuals with the Down’s syndrome deserves special attention because, besides specific anatomical and physiological alterations, some aspects also interfere in this process. Among them, the parents’behavior is the one that counts most, and it’s essential to establish a healthy diet. Facing this, the objective in this study was to assess the habitual diet in eight overweight adolescents with the Down’s syndrome living in the South Region of Tocantins State. These adolescents are between 10 and 19 years of age. To instrumentalize the referred assessment, the Food Frequency Questionnaire for Adolescents was applied and it was compared with the Adapted Food Pyramid recommendations. It was observed 82% of the adolescents used to eat less than the recommended amount of the vegetables and cereal/bread/tubers/roots; 68% eat less fruits and 87% eat less milk/dairy products groups. It was also detected an exaggeration in the consumption of grains, meat/eggs and sugar/candy groups. It was concluded that the adolescents habitually keep a diet out of the pattern considered healthy. It’s predominantly easy chewing food and high in calories, what may bring risks of getting overweight and even obese. Thus, it’s vital to go through an eating re-education process, in whichthe family has participation, so that changes in the eating habits may be achieved.

    Different systems for habitual versus goal-directed control are thought to underlie human decision-making. Working memory is known to shape these decision-making systems and their interplay, and is known to support goal-directed decision making even under stress. Here, we investigated if and how decision systems are differentially influenced by breaks filled with diverse everyday life activities known to modulate working memory performance. We used a within-subject design where young adults listened to music and played a video game during breaks interleaved with trials of a sequential two-step Markov decision task, designed to assess habitual as well as goal-directed decision making. Based on a neurocomputational model of task performance, we observed that for individuals with a rather limited working memory capacity video gaming as compared to music reduced reliance on the goal-directed decision-making system, while a rather large working memory capacity prevented such a decline. Our findings suggest differential effects of everyday activities on key decision-making processes.

    Full Text Available En esta entrevista, Giovanni Levi - como un conocedor del tema de Familia - realiza una importante evaluación sobre el actual estado de las investigaciones realizadas en el Brasil y em el exterior. Con estilo franco, agudo y lucido critica las visiones tradicionales y sus ilusiones ypropone nuevos conceptos y métodos. La historia de la familia debería ceder espacio para el estudio de las redes relacionales o de los mundos relacionales. De la misma forma, la historia cuantitativa debería abrir espacio para el estudio de las cualidades. Ya con relación a la historia de las elites, tan estudiada y reproducida en una diversidad de trabajos, que deberíase mirar en otra perspectiva. Es decir, no mirar a las reglas sociales predeterminadas, sino a los desvíos y a las variaciones. Levi defiende que los historiadores deben trascender a los documentos que se encuentran fácilmente y que pueden fortalecer perspectivas deformadas y esequilibradas de la sociedad. Para él, los historiadores deben esforzarse por estudiar a aquellos grupos que dejaron pocos rastros documentales. En ese esfuerzo existiría una nueva mirada sobre la historia de la familia.

    2013-01-01

    This paper presents a novel bio-inspired habituation function for robots under control by an artificial spiking neural network. This non-associative learning rule is modelled at the synaptic level and validated through robotic behaviours in reaction to different stimuli patterns in a dynamical virtual 3D world. Habituation is minimally represented to show an attenuated response after exposure to and perception of persistent external stimuli. Based on current neurosciences research, the originality of this rule includes modulated response to variable frequencies of the captured stimuli. Filtering out repetitive data from the natural habituation mechanism has been demonstrated to be a key factor in the attention phenomenon, and inserting such a rule operating at multiple temporal dimensions of stimuli increases a robot's adaptive behaviours by ignoring broader contextual irrelevant information.

    Animals can habituate to certain repeated stressors and reduce the physiological response that such stressor evoked initially. Studies related to stress habituation in fish are scarce and the available data differ depending on the species and on the type, duration and severity of the stressor...... no significant changes in serotonergic activity. However, incremented serotonergic activity was detected in fish previously trained. Furthermore, dopaminergic activity decreased in diurnal trained and nocturnal trained groups with respect to ST/naïve fish. Crh expression in hypothalamus was higher in ST...... for the animals to habituate, indicating that repeated chasing within short periods should be avoided when manipulating fish in order to keep proper welfare conditions in this species....

    Full Text Available El herpesvirus equino (EHV es uno de los patógenos virales de mayor importancia en la industria equina mundial, debido a las grandes pérdidas económicas que acarrea. La enfermedad comúnmente asociada con el EHV se denomina rinoneumonitis equina y se caracteriza por ser una infección primaria del tracto respiratorio superior, que progresa a través de la mucosa; puede causar aborto en los últimos meses de gestación, muerte perinatal de potros, mortinatos y mieloencefalitis. La infección productiva es seguida por un estado de latencia viral, etapa en la cual el animal no presenta ningún signo clínico de enfermedad y no hay replicación viral. Bajo una situación de estrés, el virus puede reactivarse y caballos infectados infectar a otros caballos sanos. En esta revisión se presenta de manera sintetizada, los principales hallazgos relacionados con la replicación viral y patogénesis molecular del EHV, relacionando además las proteínas implicadas en la regulación de la replicación del genoma, todas las glicoproteínas estructurales que han sido estudiadas hasta el momento y que son el eje central de investigación de distintos grupos en el mundo. Se discute además, la verdadera importancia de la dispersión directa célula-célula del virus, la formación de placas, el crecimiento in vitro y en algunos casos, la asociación con la patogénesis, bien sea en un modelo animal o en el hospedero natural.
