Revista chilena de pediatría , 1998,
Abstract: Objetivo: determinar si el pH gástrico intramucoso (pHi) ofrece información útil acerca del estado hemodinámica y contribuye a delinear el pronostico en ni os con fallo circulatorio periférica (choque. Pacientes y método: Se estudiaron siete ni os de 4 a 14 (x = 8,5) anos de edad, con cheque, que requirieron catéter en la arteria pulmonar. En lodos se midió pHi simultáneamente con pH arterial (pHa), índice de entrega de oxigeno (IDO2), índice de consume de oxigeno JIVO2], saturación venosa mixta (SvO2) y concentración de lactato en la sangre arterial cada 6 horas durante 24 horas. Resultado: se encontró una correlación inversa significativa entre el IDO2 y pHi (r = -0,85) (p = 0,01]. No hubo correlación entre la concentración arterial de lactato, pHa, SvO2 y el pHi. El promedio de la concentración de lactato fue mas alto en los fallecidos que en los sobrevivientes [3,53 mmol/l vs 1,59 mmol/l; p = 0,051). Conclusión: en esta serie se encontró una correlación significativa entre pHi e IDO2, pero en e! sentido contrario al fisiologicamente esperado y no se encontró relación entre pHi y letalidad.

Revista médica de Chile , 2005,
Abstract: Extracorporeal membrane oxygenation (ECMO) improves survival in neonatal and pediatric patients with reversible severe respiratory or cardiac failure, in whom intensive treatment fails. Since 1999, a multidisciplinary team is trained to form the first neonatal-pediatric ECMO center in Chile, according to the norms of the Extracorporeal Life Support Organization (ELSO). During 2003 the first three patients were admitted to the program: a male newborn with pulmonary hypertension, a 38 days old female operated for a total anomalous pulmonary venous connection and a 3 months old male with a severe pneumonia caused by respiratory syncytial virus. They remained in ECMO for five, seven and nine days respectively and all survived to the procedure. No neurological complications were observed after one and a half year of follow up. This consolidates the first national neonatal-pediatric ECMO program, associated to ELSO. Up to date, twelve patients have been admitted to the program (Rev Méd Chile 2005; 133: 1065-70)

Abstract: Cyclosporine A (CsA) is a fungus-derived molecule with potent immunosuppressive activity that has been largely used to downregulate cell-mediated immune responses during transplantation. However, previous data have indicated that CsA shows immunomodulatory activity that relays on the antigen concentration and the dose of CsA used. To test the hypothesis that minimal doses of CsA may show different outcomes on grafts, we used an experimental model for skin transplants in mice. ICR outbred mice received skin allografts and were either treated daily with different doses of CsA or left untreated. Untreated mice showed allograft rejection within 14 days, with graft necrosis, infiltration of neutrophils and macrophages and displayed high percentages of CD8+ T cells in the spleens, which were associated with high serum levels of IL-12, IFN-g and TNF-α. As expected, mice treated with therapeutic doses of CsA (15 mg/kg) did not show allograft rejection within the follow-up period of 30 days and displayed the lowest levels of IL-12, IFN-g and TNF-α as well as a reduction in CD8+ lymphocytes. In contrast, mice treated with consecutive minimal doses of CsA (5 × 10?55 mg/kg) displayed an acute graft rejection as early as one to five days after skin allograft; they also displayed necrosis and strong inflammatory infiltration that was associated with high levels of IL-12, IFN-g and TNF-α. Moreover, the CD4+ CD25hiFoxP3+ subpopulation of cells in the spleens of these mice was significantly inhibited compared with animals that received the therapeutic treatment of CsA and those treated with placebo. Our data suggest that consecutive, minimal doses of CsA may affect Treg cells and may stimulate innate immunity.

Abstract: introduction: extubation failure (ef) is a common complication after congenital heart disease surgery (chds), ranging from 6.7% to 22%. there are few publications that identify risk factors associated with ef in these patients. objective: to determine the rate of ef after chds and identify risk factors. method: a 3 years retrospective chart review of children less than 3 years-old who underwent chds with cardiopulmonary bypass (cpb). preoperative, operative and postoperative data was collected, including cardiac defect and type of surgery repair. results: 242 children after chds were studied, with ef rate of 9.9%. significant risk factor for ef during surgery was deep hypothermic circulatory arrest (dhca) (p = 0,0043 or = 3,1) and postoperative was laryngeal stridor (p = 0,0006 or = 21,6). down syndrome and age less than 6 months were identified as independent risk factors. finally, ef was associated with longer mechanical ventilation and higher incidence of pulmonary infections. conclusions: around 10% of extubation trials failed in patients with chds and cpb, a rate that is similar to the ones reported in other clinical reviews. in our study, the main risk factors for ef were laryngeal stridor after extubation, dhca, down syndrome and age less than 6 months. the ef was associated with longer mechanical ventilation and lung infection

Abstract: abstract in mexico, vegetable production under greenhouse conditions has increased significantly in recent years; cucumber (cucumis sativus l.) production is important, representing 10% of greenhouse crops. to evaluate the effect of pruning system on yield and quality of parthenocarpic cucumbers, a study was carried out in a greenhouse at the agricultural experimental station of the sonora university, during the period september 2009 to january 2010. the treatments were three cucumber hybrids (caman, esparon, and modan), and two pruning systems (without removing the growing point of the main stem, and the growing point of the main stem removed and two lateral branches near the top of the plant allowed to grow, resulting in two branches growing downward). the experimental design was a completely randomized block design with factorial arrangement, with four replications. days to flowering and to the beginning of harvest, commercial production (fruit number per plant, fruit weight and yield), as well as production quality (fruit length, diameter and firmness) were evaluated. during autumn-winter production, the agronomic management of cucumber in unheated greenhouses should be done without removing the growing point of the main stem, since the growth of new branches is delayed when the apical point of the main stem is removed and low temperatures retard the growth of secondary branches; this technique also requires less labor. precocity was not observed in any of the hybrids, or due to pruning system; flowering began at 33 days after sowing and harvest at 69 days. the fruit number per plant in esparon was greater with respect to caman and modan when the growing point of the main stem was not removed, with 17.7 fruit plant-1; its implementation is recommended, since it also presented a low percentage of male flowers and fewer double fruit. fruit weight and quality parameters were within the standards established for american type cucumbers, with an average weight of 330

El papel de la antropología forense en la identificación de las víctimas del holocausto del Palacio de Justicia, Bogotá, Colombia (1985)
Rodríguez C. José V.
Maguaré , 2010,
Abstract: En noviembre de 1985 el grupo armado M-19 se tomó el Palacio de Justicia del Estado colombiano, un acto sucedido por la retoma del recinto por parte de las fuerzas armadas de Colombia. Tiempo después de la toma y la retoma del Palacio, se comprobó que la identificación de las víctimas que dejaron estos sucesos se vio alterada por la acción de las fuerzas militares, algunos de cuyos comandantes fueron comprometidos penalmente por el delito de desaparición forzada. El artículo muestra parte de los resultados de la investigación sobre los hechos del Palacio; además, presenta la metodología de investigación y los resultados de la revisión de los restos óseos de la fosa común del Cementerio del Sur, en Bogotá, en donde fueron enterrados los cuerpos de las víctimas, entre las que se cuentan civiles y guerrilleros. Todo tiene como objetivo mostrar el papel de la antropología forense en la identificación de personas.

Abstract: The study aims to evaluate the effectiveness of an intervention of psychotherapy in improving the mental health and Quality of life of caregivers. This intervention is based on theoretical approaches to care adjusted to cognitive theory, in order to be applied in primary health care centres.This is multicentre clinical trials study, randomized in two parallel groups, carry out in two PHC, Study population: 150 caregivers will be included by consecutive sampling and they will be randomized the half to experimental group and the other half to control group. They provide mostly all the assistance to care-dependent familiars receiving attention in PHC Centers.Measurements: Each caregiver will be evaluated on a personal interview. The caregivers' assessment protocol: 1) Assessment of different socio-demographic related to care, and caregiver's personal situation. 2)Care-dependent individuals will also be assessed by Barthel Index and Pfeiffer Questionnaire (SPMSQ). 3)Change in caregivers will be the principal measure: family function (Family APGAR Questionnaire), burden short questionnaire (Short Zarit Burden Interview), quality of life (Ruiz & Baca: 1993 Questionnaire), the Duke-UNK Functional Social Support Questionnaire, the General Health Questionnaire-12, and changes in Dysfunctional Thoughts about caring. 4) Intervention implementation measures will also be assessed.Intervention: A psychotherapeutic intervention will be 8 sessions of 90 minutes in groups. This intervention has been initially developed for family caregivers of patients with dementia.Psychotherapeutic interventions have been proved to obtain better results to reduce symptomatology and improve emotional state of caregivers. Moreover, this intervention has been proved to be effective in a different setting other than PHC, and was developed by professionals of Mental Health. If we found that this intervention is effective in PHC and with our professionals, it would be an important instrument to offer to
