Adherencia al tratamiento en la esquizofrenia

[Es]La adherencia al tratamiento es un problema real en los pacientes esquizofrénicos, que dificulta su inserción en la sociedad y puede ocasionarles graves repercusiones médicas. Por ello, el objetivo de esta revisión es valorar la eficacia de las intervenciones psicoeducacionales con la ayuda del personal sanitario y/o familiares, en la adherencia al tratamiento de los pacientes esquizofrénicos. Se realizó una revisión sistemática para dar respuesta al objetivo planteado, analizando las respuestas de los individuos para las diferentes intervenciones realizadas con el apoyo de los profesionales sanitarios y/o familiares. Se incluyeron nueve artículos: 4 revisiones sistemáticas y 5 estudios randomizados. En los resultados se encontraron factores de riesgo clave que proporcionaban una mayor probabilidad de no-adherencia, lo que llevaba a más recaídas y peor pronóstico para la persona. Las intervenciones realizadas con los pacientes mejoraban esa adherencia a lo largo del tiempo. Se concluye por tanto que mejorar la adherencia al tratamiento en la esquizofrenia es un factor clave para los pacientes, su familia y la sociedad. Esto podría lograrse incidiendo en la adherencia al tratamiento y con un seguimiento por parte del personal sanitario.

Leukemia-Associated Mutations in Nucleophosmin Alter Recognition by CRM1: Molecular Basis of Aberrant Transport

Nucleophosmin (NPM) is a nucleocytoplasmic shuttling protein, normally enriched in nucleoli, that performs several activities related to cell growth. NPM mutations are characteristic of a subtype of acute myeloid leukemia (AML), where mutant NPM seems to play an oncogenic role. AML-associated NPM mutants exhibit altered subcellular traffic, being aberrantly located in the cytoplasm of leukoblasts. Exacerbated export of AML variants of NPM is mediated by the nuclear export receptor CRM1, and due, in part, to a mutationally acquired novel nuclear export signal (NES). To gain insight on the molecular basis of NPM transport in physiological and pathological conditions, we have evaluated the export efficiency of NPM in cells, and present new data indicating that, in normal conditions, wild type NPM is weakly exported by CRM1. On the other hand, we have found that AML-associated NPM mutants efficiently form complexes with CRM1HA (a mutant CRM1 with higher affinity for NESs), and we have quantitatively analyzed CRM1HA interaction with the NES motifs of these mutants, using fluorescence anisotropy and isothermal titration calorimetry. We have observed that the affinity of CRM1HA for these NESs is similar, which may help to explain the transport properties of the mutants. We also describe NPM recognition by the import machinery. Our combined cellular and biophysical studies shed further light on the determinants of NPM traffic, and how it is dramatically altered by AML-related mutations.

The Interplay between Natural Selection and Susceptibility to Melanoma on Allele 374F of SLC45A2 Gene in a South European Population

We aimed to study the selective pressures interacting on SLC45A2 to investigate the interplay between selection and susceptibility to disease. Thus, we enrolled 500 volunteers from a geographically limited population (Basques from the North of Spain) and by resequencing the whole coding region and intron 5 of the 34 most and the 34 least pigmented individuals according to the reflectance distribution, we observed that the polymorphism Leu374Phe (L374F, rs16891982) was statistically associated with skin color variability within this sample. In particular, allele 374F was significantly more frequent among the individuals with lighter skin. Further genotyping an independent set of 558 individuals of a geographically wider population with known ancestry in the Spanish population also revealed that the frequency of L374F was significantly correlated with the incident UV radiation intensity. Selection tests suggest that allele 374F is being positively selected in South Europeans, thus indicating that depigmentation is an adaptive process. Interestingly, by genotyping 119 melanoma samples, we show that this variant is also associated with an increased susceptibility to melanoma in our populations. The ultimate driving force for this adaptation is unknown, but it is compatible with the vitamin D hypothesis. This shows that molecular evolution analysis can be used as a useful technology to predict phenotypic and biomedical consequences in humans.

Identification of the main allergen sensitizers in an Iran asthmatic population by molecular diagnosis

Background: There has been a significant growth in the prevalence of allergy, mainly associated to IgE-mediated disorders such as asthma and rhinitis. The identification of atopy in asthmatic patients through the measurement of specific IgE can help to identify risk factors that cause asthmatic symptoms in patients. The development and use of individualized allergen-based tests by the Component Resolved Diagnosis has been a crucial advance in the accurate diagnosis and control of allergic patients. The objective of this work was to assess the usefulness of molecular diagnosis to identify environmental allergens as possible factors influencing the development and manifestation of asthma in a group of asthmatic patients from Iran. Methods: Studied population: 202 adult asthmatic patients treated at the Loghman Hakim Hospital and Pasteur Institute of Teheran (Iran) from 2011 to 2012. Specific IgE determined by the ImmunoCAP system were used to both evaluate the patients' atopic condition and the molecules involved in the allergic sensitization. SDS-PAGE IgE-immunoblotting associated with mass spectrometry was carried out to study the cockroach IgE-binding sensitizing proteins. Results: Forty-five percent of all patients could be considered atopic individuals. Eighty-two percent of atopic patients were sensitized to pollen allergens. The Salsola kali (Sal k 1) and the Phleum pratense (rPhl p 1 and/or rPhl p 5) major allergens were the most common sensitizers among pollens (71% and 18%, respectively). Thirty-five percent of the atopic population was sensitized to cockroach. Four different allergens, including a previously unknown alpha-amylase, were identified in the cockroach extract. No significant associations could be demonstrated between the severity of asthma and the specific IgE levels in the atopic population. Statistical analysis identified the Sal k 1 as the main protein allergen influencing the development and expression of asthma in the studied population. Conclusions: Pollen and cockroach were the most relevant allergen sources in the asthmatic population. The Salsola kali major allergen was the main cause for sensitization in the atopic patients suffering asthma. Using the Component Resolved Diagnosis, it was possible to identify a new Blattella germanica cockroach allergen (Blattella alpha amylase 53 kDa) that could sensitize a relevant percentage of this population.

Linhas entrelaçadas no discurso profético de Padre Antonio Vieira

O presente trabalho se propõe a analisar o discurso profético de Padre Antônio Vieira, por meio das obras Esperanças de Portugal. Quinto Império do Mundo e Livro Anteprimeiro da História do Futuro. A construção singular de tais textos será evidenciada a partir da articulação de três importantes conexões: conexão teológico-política; conexão mística e conexão histórica. Assim, a partir da abordagem de elementos biográficos e de uma reconstrução sócio-histórica, demonstraremos a lógica peculiar dessa escrita marcada pelo risco, pela fé e pelo delírio

Penaeus indicus H. Milne Edwards, 1837: resumo das conclusões dos cruzeiros de pesca exploratória entre 1979 e 1983 no banco de Sofala em Moçambique

From 1979 to 1983, several surveys were carried out with research and fishing vessels at Sofala Bank in Mozambique. Their main objective was the assessment of shallow water prawn stocks, as this resource is of great economic importance for the country. A summary of the conclusions of these surveys regarding the species Penaeus indicus is presented. During the rainy season the species occurs closer to the shore than during the dry season. Estimates of biomass are very variable. The spawning peak seems to occur at the beginning of the rainy season (September-October). The spawning areas are located very close to the shore in the northern part of Sofala Bank and South of 17 degree 10'S in the 15-25 m depth interval.

Nada além da verdade? a consolidação do direito à verdade e seu exercício por comissões e tribunais

O trabalho expõe a consolidação do direito à verdade pelo Direito Internacional e a complementaridade entre as comissões da verdade e os tribunais, mecanismos de justiça de transição, como a combinação que melhor lhe confere aplicabilidade. Primeiramente, a tese reivindica que a transição e a consolidação democrática devem se dar por meio da prestação de contas com o passado, o que se torna possível na medida em que se promoveram a partir da 2a Guerra Mundial significativas alterações no Direito Internacional, que se afasta do paradigma vesfaliano de soberania. Aborda-se assim o excepcional desenvolvimento do Direito Internacional dos Direitos Humanos, do Direito Internacional Humanitário e do Direito Penal Internacional, centralizados na ideia de responsabilidade. A tese também abrange o desenvolvimento do direito à verdade no seio da Organização das Nações Unidas e dos sistemas regionais de proteção de direitos humanos, tendo alcançado o status de norma imperativa ou peremptória, sendo explorados os obstáculos ao seu exercício como no caso de anistias e outras medidas similiares como a prescrição, a justiça militar e a coisa julgada. Enfrentam-se, ainda, as potencialidades e limites da verdade que resulta de comissões da verdade e dos tribunais, concebida esta como conhecimento sobre os fatos e o reconhecimento da responsabilidade pelo ocorrido. O trabalho aborda temas como a independência e imparcialidade das comissões de verdade, seus poderes e o alcance de suas conclusões e recomendações. Por sua vez, com vistas a identificar as verdades a serem alcançadas pelos tribunais, privilegia-se o processo criminal, por se entender que a sentença penal pressupõe o exercício mais completo do devido processo. A imperatividade do direito à verdade é também demonstrada pela defesa da participação da vítima no processo criminal e da admissão de culpa por parte do acusado -- ambos consagrados pelo Tratado de Roma. Por fim, a tese analisa alguns cenários para a complementaridade entre estes dois mecanismos de justiça de transição, fazendo o estudo dos casos do Chile, Peru, Serra Leoa e Quênia, casos estes permeados pelo Direito Internacional, seja pela influência da jurisdição universal ou pelo impacto da jurisdição internacional. O caso brasileiro, por certo, não se ajusta a nenhum destes cenários. Sua caracterização como um diálogo em aberto, para efeitos deste trabalho, pressupõe que o Brasil encontra-se em um importante momento de decisão sobre a complementaridade entre comissões da verdade e tribunais - a recente aprovação da Comissão Nacional da Verdade deve conviver com o aparente conflito entre a decisão do Supremo Tribunal Federal, que afirmou a constitucionalidade da Lei de Anistia de 1979, e a decisão da Corte Interamericana no caso Araguaia, que entende nulos os dispositivos da lei que obstaculizam o processamento dos responsáveis, ambas no ano de 2010 - com a oportunidade de demonstrar que a passagem do tempo não arrefece as obrigações a que se comprometeu no cenário internacional.

O corpo na clínica psicanalítica: inibição, sintoma e angústia

Investiga-se, nesta tese, o corpo, a partir da trilogia freudiana: inibição, sintoma e angústia. De forma particular, interessam à pesquisa o corpo ideal, propagado pela cultura, e seus efeitos. Para tanto, desenvolvemos os elementos teóricos de Freud e Lacan, a partir dos quais se dividiu a tese em três partes. Na primeira parte, considerou-se o conceito de inibição ao lado do da imagem, privilegiando-se o corpo, seu caráter de imagem e a anorexia. O estudo se baseou na teoria freudiana do narcisismo, incluindo-se seus derivados, as noções de Eu ideal, Ideal do Eu e o Estádio do Espelho lacaniano. Na intenção de ilustrar a busca imperativa por um corpo ideal, apresentou-se um caso clínico. Demarquei a segunda parte desta tese elucidando o sintoma no corpo. Para verificar sua incidência, revisitou-se a História, desde Hipócrates até o início da psicanálise, quando a histeria aparece na clínica; ressaltando-se alguns casos clínicos da clínica freudiana. Verifiquei que o corpo tem ressonância com alguns conceitos essenciais da psicanálise, tal como a pulsão e o inconsciente, além de ilustrarem sua relação com o narcisismo, o sintoma e a angústia. Na terceira parte, privilegiei o estudo da angústia relacionada ao corpo em Freud e Lacan, e o referencial usado para essa etapa foi a clínica da fobia. Procurou-se, ainda, exemplificar as diversas figuras do corpo tal como modificado na atualidade. Como resultado desta pesquisa, verificou-se que ser dono do próprio corpo não significa ficar reduzido a ele, mas apropriar-se de sua imagem. Embora o corpo fale através de seus sintomas, ele pode também ganhar nova moldura, através dos significantes constituídos pela linguagem. Foi possível constatar, como as diferentes dimensões do corpo é ligada aos três registros propostos por Lacan: imaginário, simbólico e real, percebendo-se, por fim, o lugar que o corpo ganha na topologia borromeana, na última etapa do ensino de Lacan.

Involvement of ANXA5 and ILKAP in Susceptibility to Malignant Melanoma

Single nucleotide-polymorphisms (SNPs) are a source of diversity among human population, which may be responsible for the different individual susceptibility to diseases and/or response to drugs, among other phenotypic traits. Several low penetrance susceptibility genes associated with malignant melanoma (MM) have been described, including genes related to pigmentation, DNA damage repair and oxidative stress pathways. In the present work, we conducted a candidate gene association study based on proteins and genes whose expression we had detected altered in melanoma cell lines as compared to normal melanocytes. The result was the selection of 88 loci and 384 SNPs, of which 314 fulfilled our quality criteria for a case-control association study. The SNP rs6854854 in ANXA5 was statistically significant after conservative Bonferroni correction when 464 melanoma patients and 400 controls were analyzed in a discovery Phase I. However, this finding could not be replicated in the validation phase, perhaps because the minor allele frequency of SNP rs6854854 varies depending on the geographical region considered. Additionally, a second SNP (rs6431588) located on ILKAP was found to be associated with melanoma after considering a combined set of 1,883 MM cases and 1,358 disease-free controls. The OR was 1.29 (95% CI 1.12-1.48; p-value= 4x10(-4)). Both SNPs, rs6854854 in ANXA5 and rs6431588 in ILKAP, show population structure, which, assuming that the Spanish population is not significantly structured, suggests a role of these loci on a specific genetic adaptation to different environmental conditions. Furthermore, the biological relevance of these genes in MM is supported by in vitro experiments, which show a decrease in the transcription levels of ANXA5 and ILKAP in melanoma cells compared to normal melanocytes.

Human Endogenous Retrovirus HERV-Fc1 Association with Multiple Sclerosis Susceptibility: A Meta-Analysis

Background: Human endogenous retroviruses (HERVs) are repetitive sequences derived from ancestral germ-line infections by exogenous retroviruses and different HERV families have been integrated in the genome. HERV-Fc1 in chromosome X has been previously associated with multiple sclerosis (MS) in Northern European populations. Additionally, HERV-Fc1 RNA levels of expression have been found increased in plasma of MS patients with active disease. Considering the North-South latitude gradient in MS prevalence, we aimed to evaluate the role of HERV-Fc1on MS risk in three independent Spanish cohorts. Methods: A single nucleotide polymorphism near HERV-Fc1, rs391745, was genotyped by Taqman chemistry in a total of 2473 MS patients and 3031 ethnically matched controls, consecutively recruited from: Northern (569 patients and 980 controls), Central (883 patients and 692 controls) and Southern (1021 patients and 1359 controls) Spain. Our results were pooled in a meta-analysis with previously published data. Results: Significant associations of the HERV-Fc1 polymorphism with MS were observed in two Spanish cohorts and the combined meta-analysis with previous data yielded a significant association [rs391745 C-allele carriers: p(M-H) = 0.0005; ORM-H (95% CI) = 1.27 (1.11-1.45)]. Concordantly to previous findings, when the analysis was restricted to relapsing remitting and secondary progressive MS samples, a slight enhancement in the strength of the association was observed [p(M-H) = 0.0003, ORM-H (95% CI) = 1.32 (1.14-1.53)]. Conclusion: Association of the HERV-Fc1 polymorphism rs391745 with bout-onset MS susceptibility was confirmed in Southern European cohorts.

Temperature-and pH-Sensitive Nanohydrogels of Poly(N-Isopropylacrylamide) for Food Packaging Applications: Modelling the Swelling-Collapse Behaviour

Temperature-sensitive poly(N-isopropylacrylamide) (PNIPA) nanohydrogels were synthesized by nanoemulsion polymerization in water-in-oil systems. Several cross-linking degrees and the incorporation of acrylic acid as comonomer at different concentrations were tested to produce nanohydrogels with a wide range of properties. The physicochemical properties of PNIPA nanohydrogels, and their relationship with the swelling-collapse behaviour, were studied to evaluate the suitability of PNIPA nanoparticles as smart delivery systems (for active packaging). The swelling-collapse transition was analyzed by the change in the optical properties of PNIPA nanohydrogels using ultraviolet-visible spectroscopy. The thermodynamic parameters associated with the nanohydrogels collapse were calculated using a mathematical approach based on the van't Hoff analysis, assuming a two-state equilibrium (swollen to collapsed). A mathematical model is proposed to predict both the thermally induced collapse, and the collapse induced by the simultaneous action of two factors (temperature and pH, or temperature and organic solvent concentration). Finally, van't Hoff analysis was compared with differential scanning calorimetry. The results obtained allow us to solve the problem of determining the molecular weight of the structural repeating unit in cross-linked NIPA polymers, which, as we show, can be estimated from the ratio of the molar heat capacity (obtained from the van't Hoff analysis) to the specific heat capacity (obtained from calorimetric measurements).
