Cambios en los cuidadores informales en cuanto a estilos de vida, relaciones y alteraciones de salud mental

Changes in the informal caregiver life styles, relations and alterations of mental health. Justification.The increase of the population aged 65 years and older in developed countries is generating a proportional increasing of the dependency caused by chronic pathologies. The care of these persons is being carried out by relatives, informal carers, leading to some alterations in diverse areas, among them mental alterations, as a consequence of taking care. Objectives. To develop a profile of the informal carers and to correlate the caregiver burden with the carers disorders. To detect risk factors to allow carrying out premature nursing interventions to diminish the disorders in the informal carers. Design. An observational and cross-sectional study is made in primary care health services area of the city of Girona. Methodology. Random sample of carer of dependent people at their home , assigned to the program of domiciliary attention (ATDOM) of the educational basic areas of health (ABS). A sample size of 269 persons, with a level of precision of 9% was needed. Questionnaire ICUB 97, the test of Barthel, the Philadelphia Geriatric Center scale, and a questionnaire are used as instruments that includes demographic and social variables, and mental and physical carers disorders.Results. A total of 80 participants were interviewed. The most common problems as consequence of taking care were the backache, to feel more tired, to feel impotent and to have less free time. Correlation between the level of dependence of the patient with the number of problems perceived by the caretaker does not exist. Since they are informal carers they eat frequently outside the habitual schedule, took place an increase or loss of weight, experienced more disorders in sexual life and an increasing lack of interest in surroundings. A 33% of the informal carers are being treated for problems related to the mental health.Conclusion. The fact of being informal carer carries important consequences in their health, the lifestyles and the social relations. These can be attenuated if the nursing interventions are able to consider to the well-taken care of subject, and its surroundings in an holistic way. The professionals of infirmary of mental health must contribute to their knowledge and abilities contributing to make an assessment, a diagnosis and an intervention paying special attention to psycho-social aspects mentioned

Crucial role of CB(2) cannabinoid receptor in the regulation of central immune responses during neuropathic pain

Neuropathic pain is a clinical manifestation of nerve injury difficult to treat even with potent analgesic compounds. Here, we used different lines of genetically modified mice to clarify the role played by CB2 cannabinoid receptors in the regulation of the central immune responses leading to the development of neuropathic pain. CB2 knock-out mice and wild-type littermates were exposed to sciatic nerve injury, and both genotypes developed a similar hyperalgesia and allodynia in the ipsilateral paw. Most strikingly, knock-outs also developed a contralateral mirror image pain, associated with an enhanced microglial and astrocytic expression in the contralateral spinal horn. In agreement, hyperalgesia, allodynia, and microglial and astrocytic activation induced by sciatic nerve injury were attenuated in transgenic mice overexpressing CB2 receptors. These results demonstrate the crucial role of CB2 cannabinoid receptor in modulating glial activation in response to nerve injury. The enhanced manifestations of neuropathic pain were replicated in irradiated wild-type mice reconstituted with bone marrow cells from CB2 knock-outs, thus demonstrating the implication of the CB2 receptor expressed in hematopoietic cells in the development of neuropathic pain at the spinal cord.

Interferon-gamma is a critical modulator of CB(2) cannabinoid receptor signaling during neuropathic pain

Nerve injuries often lead to neuropathic pain syndrome. The mechanisms contributing to this syndrome involve local inflammatory responses, activation of glia cells, and changes in the plasticity of neuronal nociceptive pathways. Cannabinoid CB(2) receptors contribute to the local containment of neuropathic pain by modulating glial activation in response to nerve injury. Thus, neuropathic pain spreads in mice lacking CB(2) receptors beyond the site of nerve injury. To further investigate the mechanisms leading to the enhanced manifestation of neuropathic pain, we have established expression profiles of spinal cord tissues from wild-type and CB(2)-deficient mice after nerve injury. An enhanced interferon-gamma (IFN-gamma) response was revealed in the absence of CB(2) signaling. Immunofluorescence stainings demonstrated an IFN-gamma production by astrocytes and neurons ispilateral to the nerve injury in wild-type animals. In contrast, CB(2)-deficient mice showed neuronal and astrocytic IFN-gamma immunoreactivity also in the contralateral region, thus matching the pattern of nociceptive hypersensitivity in these animals. Experiments in BV-2 microglia cells revealed that transcriptional changes induced by IFN-gamma in two key elements for neuropathic pain development, iNOS (inducible nitric oxide synthase) and CCR2, are modulated by CB(2) receptor signaling. The most direct support for a functional involvement of IFN-gamma as a mediator of CB(2) signaling was obtained with a double knock-out mouse strain deficient in CB(2) receptors and IFN-gamma. These animals no longer show the enhanced manifestations of neuropathic pain observed in CB(2) knock-outs. These data clearly demonstrate that the CB(2) receptor-mediated control of neuropathic pain is IFN-gamma dependent.

Cada paciente por el que se consultó fue evaluado y programado para visita siguiendo un protocolo claramente definido. En cada visita se registraron variables demográficas y clínicas y se evaluaron el dolor, anorexia, estreñimiento, insomnio, debilidad, ansiedad y depresión. La eficacia en el control sintomático se analizó para aquellos pacientes que fueron capaces de hacer tres visitas consecutivas. Resultados: referente al proceso de citación fueron evaluables 2.385 pacientes. El 80% de los pacientes programados vinieron a visita y la mediana de tiempo entre la demanda y la visita fueron de 10 días. La evaluación del control sintomático fue posible para 553 pacientes, mostrando un significativo buen control de todos los síntomas con excepción de la astenia. El 55% de los pacientes requirieron opioides para el dolor, observándose un cambio en el patrón pasando de morfina a fentanilo TTS. Conclusiones: la carga asistencial, en nuestro centro, en la consulta externa de cuidados paliativos es alta. Los resultados del proceso de citación muestran un alto cumplimiento con un mínimo tiempo de espera entre la petición y la visita. Los resultados clínicos muestran un buen control global de los síntomas con excepción de la astenia. También se observa un cambio en el patrón de la perscripción de opioides. Este estudio ha de ser considerado como la línea basal para futuros estudios de nuestro centro o en otros de características similares

Síndrome de boca ardiente: claves diagnósticas y terapéuticas

El síndrome de boca ardiente (SBA) se conoce también como boca escaldada, ardor bucal, glosodinia, glosopirosis, estomatodinia, estomatopirosis o disestesia oral. Se caracteriza por dolor o sensación de ardor, escozor o picazón, a veces aspereza, sobre todo en la lengua, paladar duro y labio inferior, en ausencia de datos clínicos o de laboratorio que justifiquen estos síntomas. Puede acompañarse de disgeusia (trastornos del gusto) y de xerostomía (boca seca), constituyendo la tríada clásica. Su etiología, poco precisa, es multifactorial. La evolución del cuadro tiende a ser crónica, alternando períodos de exacerbación y mejoría durante meses o años. Es más frecuente en mujeres perimenopáusicas o posmenopáusicas. Los episodios de SBA aparecen de forma espontánea y presentan un abanico variable en la gravedad de los síntomas. Mientras algunos pacientes refieren malestar leve o moderado, otros manifiestan dolor insoportable. Los síntomas suelen ser menos intensos...

Trocas gasosas e conteúdo de carboidratos e compostos nitrogenados em pinhão-manso irrigado com águas residuária e salina

O objetivo deste trabalho foi avaliar alterações nas trocas gasosas e nos conteúdos de carboidratos e compostos nitrogenados, em pinhão-manso (Jatropha curcas) irrigado com águas residuária e salina. Empregou-se o delineamento em blocos ao acaso, com quatro tratamentos e quatro repetições: irrigação plena com água de abastecimento a 0,6 dS m-1 (controle); irrigação plena com água salinizada a 2,4 dS m-1 (SAL); e irrigação com água residuária de esgoto, plena (R100) e a 50% da capacidade de campo (R50). O tratamento R50 reduziu fortemente as trocas gasosas e a área foliar, comparado ao controle, seguido pelos tratamentos SAL e R100. A redução na fotossíntese diminuiu o nível de sacarose nas folhas, nos quatro tratamentos. Os teores de açúcares solúveis aumentaram nos tratamentos R50, SAL e R100, enquanto o conteúdo de amido permaneceu praticamente inalterado. Os conteúdos de prolina e glicina betaína aumentaram nos três tratamentos, mas a última foi mais importante, em termos quantitativos, como protetor celular e osmótico. A irrigação plena com água residuária induz efeitos similares aos causados pela irrigação com água salina. A irrigação limitada com água residuária causa estresse agudo às plantas, provavelmente pela combinação de deficiência hídrica e acúmulo de solutos no solo.

Risk factors for head and neck cancer in young adults: a pooled analysis in the INHANCE consortium.

BACKGROUND: Increasing incidence of head and neck cancer (HNC) in young adults has been reported. We aimed to compare the role of major risk factors and family history of cancer in HNC in young adults and older patients. METHODS: We pooled data from 25 case-control studies and conducted separate analyses for adults ≤45 years old ('young adults', 2010 cases and 4042 controls) and >45 years old ('older adults', 17 700 cases and 22 704 controls). Using logistic regression with studies treated as random effects, we estimated adjusted odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS: The young group of cases had a higher proportion of oral tongue cancer (16.0% in women; 11.0% in men) and unspecified oral cavity / oropharynx cancer (16.2%; 11.1%) and a lower proportion of larynx cancer (12.1%; 16.6%) than older adult cases. The proportions of never smokers or never drinkers among female cases were higher than among male cases in both age groups. Positive associations with HNC and duration or pack-years of smoking and drinking were similar across age groups. However, the attributable fractions (AFs) for smoking and drinking were lower in young when compared with older adults (AFs for smoking in young women, older women, young men and older men, respectively, = 19.9% (95% CI = 9.8%, 27.9%), 48.9% (46.6%, 50.8%), 46.2% (38.5%, 52.5%), 64.3% (62.2%, 66.4%); AFs for drinking = 5.3% (-11.2%, 18.0%), 20.0% (14.5%, 25.0%), 21.5% (5.0%, 34.9%) and 50.4% (46.1%, 54.3%). A family history of early-onset cancer was associated with HNC risk in the young [OR = 2.27 (95% CI = 1.26, 4.10)], but not in the older adults [OR = 1.10 (0.91, 1.31)]. The attributable fraction for family history of early-onset cancer was 23.2% (8.60% to 31.4%) in young compared with 2.20% (-2.41%, 5.80%) in older adults. CONCLUSIONS: Differences in HNC aetiology according to age group may exist. The lower AF of cigarette smoking and alcohol drinking in young adults may be due to the reduced length of exposure due to the lower age. Other characteristics, such as those that are inherited, may play a more important role in HNC in young adults compared with older adults.

Morbilidad de la extracción de los terceros molares en pacientes entre los 12 y 18 años de edad

Objetivo: El propósito de este estudio fue analizar la incidencia de complicaciones después de la extracción quirúrgica de los terceros molares en pacientes de 12 a 18 años de edad. Pacientes y método: Se realizó un estudio retrospectivo de 390 extracciones quirúgicas de terceros molares superiores e inferiores en 173 pacientes en edades comprendidas entre los 12 y 18 años de edad, intervenidos bajo anestesia locorregional en el año 2000 en el Máster de Cirugía Bucal e Implantología Bucofacial de la Universidad de Barcelona. Los pacientes fueron divididos en tres grupos (A: 12-14 años, B:15-16 años, C: 17-18 años). Se registró la edad y el sexo del paciente, el motivo de la extracción, el grado de desarrollo dentario, la posición, la angulación y la inclusión del tercer molar. Finalmente se valoró la asociación entre dichas variables y la aparición de complicaciones postoperatorias. Resultados: La mayoría de los pacientes intervenidos fueron del sexo femenino (66,9%), y el grupo de edad en la que se realizó el mayor número de extracciones (62,8%) fue en el grupo C (17-18 años). El principal motivo de extracción fue la indicación por parte del ortodoncista (40,5%), seguido por la indicación profiláctica (39,5%). La presencia de clínica fue el motivo de extracción en un 20% de los casos. Se observó una incidencia del 15,6% de complicaciones postoperatorias tras la extracción de 390 terceros molares. En el grupo A el riesgo de complicaciones fue de 17,4%, en el grupo B de 19% y en el grupo C de 13,7%. Todas las complicaciones fueron reversibles y de corta duración como el dolor y la inflamación persistente, la infección, el trismo y la equimosis. Se presentó un caso de parestesia del nervio dentario inferior y un caso de parestesia del nervio lingual que remitieron a los 2 meses y al mes respectivamente. Conclusiones: este estudio demuestra que no hay diferencias significativas en las complicaciones observadas entre los tres grupos de edad, y por lo general, éstas son leves y reversibles. Se observó una mayor tendencia de complicaciones en las mujeres y el porcentaje de complicaciones aumenta cuanto menor es el espacio disponible para la erupción

Salivary cotinine concentrations in daily smokers in Barcelona, Spain: a cross-sectional study

Background: Characterizing and comparing the determinant of cotinine concentrations in different populations should facilitate a better understanding of smoking patterns and addiction. This study describes and characterizes determinants of salivary cotinine concentration in a sample of Spanish adult daily smoker men and women. Methods: A cross-sectional study was carried out between March 2004 and December 2005 in a representative sample of 1245 people from the general population of Barcelona, Spain. A standard questionnaire was used to gather information on active tobacco smoking and passive exposure, and a saliva specimen was obtained to determine salivary cotinine concentration. Two hundred and eleven adult smokers (>16 years old) with complete data were included in the analysis. Determinants of cotinine concentrations were assessed using linear regression models. Results: Salivary cotinine concentration was associated with the reported number of cigarettes smoked in the previous 24 hours (R2 = 0.339; p < 0.05). The inclusion of a quadratic component for number of cigarettes smoked in the regression analyses resulted in an improvement of the fit (R2 = 0.386; p < 0.05). Cotinine concentration differed significantly by sex, with men having higher levels. Conclusion: This study shows that salivary cotinine concentration is significantly associated with the number of cigarettes smoked and sex, but not with other smoking-related variables.

Polychlorinated and polybrominated biphenyls

This volume of the IARC Monographs provides evaluations of the carcinogenicity of polychlorinated biphenyls and polybrominated biphenyls. Polychlorinated biphenyls are a class of aromatic compounds comprising 209 congeners, each containing 1 to 10 chlorine atoms attached to a biphenyl nucleus. Technical products, which were manufactured to obtain a certain degree of chlorination, are mixtures of numerous congeners. These products were widely used as dielectric fluid in capacitors and transformers, and to a lesser extent in building materials. Although their production and use has been banned in most countries, these compounds are ubiquitous environmental pollutants, including in polar regions and the deep ocean, because they are persistent and bioaccumulate. Worldwide monitoring programmes have shown that polychlorinated biphenyls are present in most samples of human milk. An IARC Monographs Working Group reviewed epidemiological evidence, animal bioassays, and mechanistic and other relevant data to reach conclusions as to the carcinogenic hazard to humans of polychlorinated biphenyls, of the subclass of dioxinlike polychlorinated biphenyls, and of polybrominated biphenyls.

Torção hepática e obstrução de cólon transverso: relato de um caso e revisão da literatura

Os autores relatam o caso de uma paciente de 20 anos de idade, sem antecedentes patológicos, que apresentou quadro de abdome agudo obstrutivo. Realizou exames radiológicos, ultra-som e tomografia computadorizada, seguidos de laparotomia exploradora, sendo constatadas: a) rotação hepática completa para o hipocôndrio esquerdo; b) hipotensão severa por compressão da veia cava inferior; c) malformação congênita dos ligamentos falciforme e coronários; d) obstrução do cólon transverso por bridas constritivas congênitas; e) importante distensão gasosa de alças cólicas no hipocôndrio direito. Foram ressecadas as bandas pericólicas, com redução imediata da dilatação no hemiabdome direito, havendo retorno espontâneo do fígado à posição anatômica. Esta condição ímpar, e os outros três casos similares já descritos na literatura mundial, são comentados neste trabalho.
