Resiliencia psicológica y dolor crónico
Ruiz Párraga,Gema Teresa; López Martínez,Alicia Eva;
Escritos de Psicología (Internet) , 2012, DOI: 10.5231/psy.writ.2012.1001
Abstract: the study of resilience continues to command wide-ranging interest, despite its long history. however, there is no universally accepted definition of resilience, despite its undoubted importance in the field of health. in this context, attention is being paid to the role played by resilience in the adaptation to physical diseases, including chronic pain. the few studies on this topic show resilience as a relevant variable in adjustment to chronic pain. nevertheless, definitive conclusions cannot be formed due to differences in the conceptualization and measurement of this variable across different studies. thus, further research in this area is needed.

Abstract: repetitive or chronic respiratory infections are common in cystic fibrosis patients, usually due to pseudomonas aeruginosa. the recommended therapy is the combination of one aminoglycoside with a beta-lactam antibiotic. for this reason, the susceptibility of 54 pseudomonas aeruginosa isolated obtained from the respiratory tract of cystic fibrosis patients to four beta-lactams was analysed. the study was performed by broth microdilution. ceftazidime was the most active agent against pseudomonas aeruginosa (85% of the total strains being susceptible).. eighty three percent of the strains were inhibited by azlocillin and 37% by carbenicillin. only 20% of all studied strains were susceptible to cefotaxime.
Sodio urinario como marcador bioquímico de la ingesta estimada de sal en ni?os y adolescentes
Maskin de Jensen,Alicia Noemí; López,Miryan Susana; Mir,Claudia Nora; Martínez,Pedro;
Acta bioqu?-mica cl?-nica latinoamericana , 2011,
Abstract: the aim of this study was to evaluate the estimated salt intake in "clinically healthy" children and adolescents, using the 24 h sodium urinary excretion as biochemical marker or indicator. a hundred and twelve male and female children aged 5 to 15, without a dietary restriction who visited the province pediatric hospital - posadas were evaluated. urinary sodium in 24 hours was measured using the electrode selective ion method. the salt intake (g/day) was calculated as: urinary sodium (mmol/day) x 58.5. there were no significant differences in estimated salt intake by gender. children aged from 9 to 15 have a significantly higher (p< 0.05) consumption (2.5 to 17 g salt /day) than those between the ages of 5 to 8 (1.3 a 11.7 g salt/day). a 24% of the children aged 5 to 8 and only a 15% at the age range 9 to 15 consume according international recommendations. the daily estimated salt intake indicates that a great percentage of the population studied presents a usual high consumption of salt, greater than their physiological needs and the recommended aims for prevention hypertension.
Trastorno de estrés postraumático y dolor crónico: nexos entre psico y pato(logía)
López Martínez,Alicia E.; Gómez Pérez,Lydia; Ruiz Párraga,Gema T.;
Escritos de Psicología (Internet) , 2009,
Abstract: the primary aim of this paper is to provide a brief review of the existing literature investigating the relationship between chronic pain and the posttraumatic stress disorder (pstd). there is a growing body of research that indicates that pstd and chronic pain frequently co-occur, and that both conditions may interact in such a way as to negatively impact the course and outcome of the treatment of either disorder. people with both health problems tend to have greater distress and impairment compared to those with only one of these conditions. in recent years, several important conceptual developments and potential mechanisms have been proposed on how and why these disorders often co-occur and how they can interact with one another. the research suggests that variables such as fear and avoidance, anxiety sensitivity, and catastrophizing, as well as general and specific psychological and biological features, may help account for the development and maintenance of both conditions.

Acta bioqu?-mica cl?-nica latinoamericana , 2011,
Abstract: El objetivo de este trabajo fue estimar la ingesta de sal en ni os y adolescentes "clínicamente sanos" utilizando como marcador o indicador bioquímico la excreción urinaria de sodio en 24 h. Se estudiaron 112 ni os de ambos sexos, entre 5 y 15 a os, sin restricción dietética, que concurrieron al Hospital de Pediatría - Posadas, Misiones. Se determinó la concentración de sodio en orina de 24 h utilizando un electrodo ión selectivo. La ingesta estimada de sal (g/día) se calculó a partir de: sodio urinario (mmol/día) x 58,5. No se encontraron diferencias significativas para la ingesta de sal por género. Los ni os entre 9 y 15 a os poseen una ingesta estimada (2,5 a 17 g sal/día) significativamente mayor (p < 0,05) que el grupo de 5 a 8 a os (1,3 a 11,7 g sal/día). Un 24% de los ni os de 5 a 8 a os y sólo el 15% del grupo etáreo de 9 a 15 a os, consumen de acuerdo a las recomendaciones establecidas por organismos internacionales. La ingesta de sal diaria estimada indica que un gran porcentaje de la población estudiada presenta una ingesta habitual elevada de sal, mayor a sus necesidades fisiológicas y a las metas recomendadas para prevenir la hipertensión arterial. O objetivo deste trabalho foi estimar a ingest o de sal em crian as e adolescentes "clinicamente saudáveis" utilizando como marcador ou indicador bioquímico a excre o urinária de sódio em 24 h. Foram estudadas 112 crian as de ambos os sexos, entre 5 e 15 anos, sem restri o dietética, que assistiram ao Hospital de Pediatria - Posadas, Misiones. Determinou-se a concentra o de sódio em urina de 24 h utilizando um eletrodo íon seletivo. A ingest o estimada de sal (g/dia) se calculou a partir do sódio urinário (mmoles/dia) x 58,5. N o se encontraram diferen as signiOcativas para a ingest o de sal por gênero. Crian as entre 9 e 15 anos têm uma ingest o estimada (2,5 a 17 g sal/dia) signiOcativamente maior (p < 0,05) que o grupo de 5 a 8 anos (1,3 a 11,7 g sal/dia). 24% das crian as de 5 a 8 anos e apenas 15% do grupo entre 9 e 15 anos, consomem conforme as recomenda es estabelecidas por organismos internacionais. A ingest o de sal diária estimada indica que um grande percentual da popula o estudada apresenta ingest o habitual elevada de sal, maior a suas necessidades Osiológicas e às metas recomendadas para prevenir hipertens o arterial.

Abstract: The primary aim of this paper is to provide a brief review of the existing literature investigating the relationship between chronic pain and the Posttraumatic Stress Disorder (PSTD). There is a growing body of research that indicates that PSTD and chronic pain frequently co-occur, and that both conditions may interact in such a way as to negatively impact the course and outcome of the treatment of either disorder. People with both health problems tend to have greater distress and impairment compared to those with only one of these conditions. In recent years, several important conceptual developments and potential mechanisms have been proposed on how and why these disorders often co-occur and how they can interact with one another. The research suggests that variables such as fear and avoidance, anxiety sensitivity, and catastrophizing, as well as general and specific psychological and biological features, may help account for the development and maintenance of both conditions.
Mytilus galloprovincialis Myticin C: A Chemotactic Molecule with Antiviral Activity and Immunoregulatory Properties

PLOS ONE , 2012, DOI: 10.1371/journal.pone.0023140
Abstract: Previous research has shown that an antimicrobial peptide (AMP) of the myticin class C (Myt C) is the most abundantly expressed gene in cDNA and suppressive subtractive hybridization (SSH) libraries after immune stimulation of mussel Mytilus galloprovincialis. However, to date, the expression pattern, the antimicrobial activities and the immunomodulatory properties of the Myt C peptide have not been determined. In contrast, it is known that Myt C mRNA presents an unusual and high level of polymorphism of unidentified biological significance. Therefore, to provide a better understanding of the features of this interesting molecule, we have investigated its function using four different cloned and expressed variants of Myt C cDNA and polyclonal anti-Myt C sera. The in vivo results suggest that this AMP, mainly present in hemocytes, could be acting as an immune system modulator molecule because its overexpression was able to alter the expression of mussel immune-related genes (as the antimicrobial peptides Myticin B and Mytilin B, the C1q domain-containing protein MgC1q, and lysozyme). Moreover, the in vitro results indicate that Myt C peptides have antimicrobial and chemotactic properties. Their recombinant expression in a fish cell line conferred protection against two different fish viruses (enveloped and non-enveloped). Cell extracts from Myt C expressing fish cells were also able to attract hemocytes. All together, these results suggest that Myt C should be considered not only as an AMP but also as the first chemokine/cytokine-like molecule identified in bivalves and one of the few examples in all of the invertebrates.
