Complicaciones de la preeclampsia severa y su relación con variables demográficas y obstétricas

Introducción: La preeclampsia severa es una de las principales patologías que afectan a las mujeres embarazadas, sus complicaciones tienen un alto impacto en la salud del binomio madre-hijo. Materiales y métodos: Se realizo una serie de casos, durante un periodo de 1 año se revisaron las historias clínicas de las pacientes que ingresaron a la unidad de cuidado intensivo obstétrico de la Clínica Orquídeas, con diagnóstico de preeclampsia severa. Se describieron los datos demográficos y las complicaciones. Se realizó análisis univariado con las variables de interés y se calcularon diferencias significativas por medio del test exacto de Fisher. Resultados: Se registraron 196 pacientes con preeclampsia severa en el periodo de estudio. Las complicaciones mas frecuentes fueron síndrome HELLP (30,6%), insuficiencia renal aguda (16,3%) y edema pulmonar (10,2%); el ingreso de las pacientes con preeclampsia severa a la UCIO en embarazo aumenta el riesgo de sufrir complicaciones. El síndrome de HELLP se presento con mayor frecuencia en pacientes que realizaron 6 o mas controles prenatales (p=0.066). Discusión: Los resultados evidencian una prevalencia de preeclampsia severa mayor que la observada por otros autores, probablemente por ser una UCI exclusivamente obstétrica. Las complicaciones mas frecuentes son concordantes con otros estudios publicados. El mayor riesgo de complicaciones asociadas en pacientes que ingresan embarazadas a la UCIO podría estar en relación a la severidad de la patología. Se requieren estudios analíticos para establecer asociaciones entre cada una de las complicaciones y sus factores condicionantes.

Sugammadex versus neostigmina en la reversión de la relajación neuromuscular en neurocirugía. Experimento clínico. Reporte preliminar

Existen grupos quirúrgicos específicos donde es mandatorio el uso de relajantes neuromusculares no despolarizantes, como es el caso de los pacientes llevados a procedimiento de neurocirugía; debido a sus características particulares el rocuronio es una buena alternativa para este tipo de procedimientos, ya sea en bolos o en infusión. Sin embargo la relajación residual y los efectos adversos de los medicamentos para revertir la relajación neuromuscular deben tenerse en cuenta en este grupo de pacientes en particular. El presente trabajo busca comparar la reversión de la relajación de infusiones de rocuronio, con Neostigmina mas Atropina vs la reversión con Sugammadex en pacientes llevados a manejo quirúrgico de lesiones supratentoriales por parte del servicio de neurocirugía de la Fundación Cardioinfantil, evaluando complicaciones durante la administración de los medicamentos y 24 horas posoperatorias, así como los tiempos para extubación y salida de salas de cirugía. Estudio con características de experimento prospectivo, aleatorizado, ciego, controlado. En este documento se realiza un reporte preliminar descriptivo de 14 pacientes reclutados hasta la actualidad.

Manifestaciones renales en pacientes con síndrome de Alagille: Reporte de casos y revisión de la literatura.

El síndrome de Alagille es una condición autosómica dominante que se define clínicamente por alteraciones de cinco sistemas principales: escasez de ductos biliares con colestasis crónica, compromiso cardíaco (estenosis pulmonar), óseo (vétebras en mariposa), oftálmico (embriotoxon posterior) y de la cara (fascies dismórficas leves pero reconocibles). La afectación renal es común en estos pacientes; sin embargo, no hace parte de los criterios que definen el síndrome. Reportamos los casos de 3 pacientes con síndrome de Alagille y compromiso renal y realizamos una revisión de la literatura para establecer la importancia de incluir la evaluación de este sistema en el diagnóstico del síndrome. Concluimos que el compromiso renal es frecuente, y por lo tanto sugerimos que en todos los casos se evalúe la posibilidad de compromiso renal tanto a nivel estructural como funcional glomerular y tubular.

"Genome-Wide Linkage in a Highly Consanguineous Pedigree Reveals Two Novel Loci on Chromosome 7 for Non-Syndromic Familial Premature Ovarian Failure"

Background: The human condition known as Premature Ovarian Failure (POF) is characterized by loss of ovarian function before the age of 40. A majority of POF cases are sporadic, but 10–15% are familial, suggesting a genetic origin of the disease. Although several causal mutations have been identified, the etiology of POF is still unknown for about 90% of the patients. Methodology/Principal Findings: We report a genome-wide linkage and homozygosity analysis in one large consanguineous Middle-Eastern POF-affected family presenting an autosomal recessive pattern of inheritance. We identified two regions with a LODmax of 3.26 on chromosome 7p21.1-15.3 and 7q21.3-22.2, which are supported as candidate regions by homozygosity mapping. Sequencing of the coding exons and known regulatory sequences of three candidate genes (DLX5, DLX6 and DSS1) included within the largest region did not reveal any causal mutations. Conclusions/Significance: We detect two novel POF-associated loci on human chromosome 7, opening the way to the identification of new genes involved in the control of ovarian development and function.

Genotyping Klebsiella pneumoniae isolated from hepatic abscesses in three patients from Bogota, Colombia

Pyogenic liver abscess caused by Klebsiella pneumoniae represents an ever increasing entity which has mainly been described as occurring in Asia, even though, on a smaller scale, cases are being more frequently described from the USA and Europe, 13% overall mortality being reached worldwide. Affected patients are severely sick, suffering from fever, sweating, having increased acute phase reactants and risk factors such as Diabetes Mellitus, alcoholism and the inherent characteristics of the bacteria causing the disease. Objective: in this work we used a Multilocus Sequencing Typing (MLST), a nucleotide sequence-based method in order to characterize the genetic relationships among bacterial isolates. Materials and methods: the report is focused on three cases involving patients suffering from pyogenic liver abscess caused by Klebsiella pneumoniae in two hospitals in Bogota, Colombia, where phenotyping and hypermucoviscosity studies were carried out, as well as the genotyping of cultured Klebsiella isolates. Reults: it was found that the isolated microorganism in cases I and II corresponded to the same K. pneumoniae strain, having 100% sequence identity for the 5 genes being studied while the strain in Case III was genotypically different. Conclusion: it is important to carry out multidisciplinary studies allowing all pyogenic liver abscess cases reported in Colombia to be complied to ascertain the frequency of microorganisms causing this pathology in our country, as well as a genotyping study of different K. pneumoniae strains to compare them and confirm clonal and pathogenicity relationships through housekeeping gene analysis.

Mobile Incubation in Waved Albatross (Phoebastria irrorata): Associated Hatching Failure and Artificial Mitigation

Waved albatrosses often relocate their eggs during incubation by placing the egg between the tarsi and shuffling forward. This behavior frequently results in eggs becoming lodged between rocks, accounting for at least 10%, and perhaps as much as 80%, of breeding failures. Because albatross populations worldwide are currently threatened, artificial means of augmenting reproductive success may be necessary to mitigate losses caused by anthropogenic effects. We characterize the frequency and extent of egg movement; test several hypotheses related to microhabitat, timing, and incubation location to explain the behavior; and investigate the utility of repositioning lodged eggs in a location in which breeding birds might resume incubation. Egg rescue increased both the likelihood of continued incubation as well as the hatching rate in our experiment, and provides an efficient, low-cost management option for this species.

Quantification of the probability of containment failure caused by an in-vessel steam explosion for the Sizewell B PWR

AEA Technology has provided an assessment of the probability of α-mode containment failure for the Sizewell B PWR. After a preliminary review of the methodologies available it was decided to use the probabilistic approach described in the paper, based on an extension of the methodology developed by Theofanous et al. (Nucl. Sci. Eng. 97 (1987) 259–325). The input to the assessment is 12 probability distributions; the bases for the quantification of these distributions are discussed. The α-mode assessment performed for the Sizewell B PWR has demonstrated the practicality of the event-tree method with input data represented by probability distributions. The assessment itself has drawn attention to a number of topics, which may be plant and sequence dependent, and has indicated the importance of melt relocation scenarios. The α-mode failure probability following an accident that leads to core melt relocation to the lower head for the Sizewell B PWR has been assessed as a few parts in 10 000, on the basis of current information. This assessment has been the first to consider elevated pressures (6 MPa and 15 MPa) besides atmospheric pressure, but the results suggest only a modest sensitivity to system pressure.

Supply, demand and a failure of understanding: addressing the culture clash between archaeologists' expectations for training and employment in 'academia' versus 'practice

A university degree is effectively a prerequisite for entering the archaeological workforce in the UK. Archaeological employers consider that new entrants to the profession are insufficiently skilled, and hold university training to blame. But university archaeology departments do not consider it their responsibility to deliver fully formed archaeological professionals, but rather to provide an education that can then be applied in different workplaces, within and outside archaeology. The number of individuals studying archaeology at university exceeds the total number working in professional practice, with many more new graduates emerging than archaeological jobs advertised annually. Over-supply of practitioners is also a contributing factor to low pay in archaeology. Steps are being made to provide opportunities for vocational training, both within and outside the university system, but archaeological training and education within the universities and subsequently the archaeological labour market may be adversely impacted upon by the introduction of variable top-up student fees.

Failure to regulate: counterproductive recruitment of top-down prefrontal-subcortical circuitry in major depression

Although depressed mood is a normal occurrence in response to adversity in all individuals, what distinguishes those who are vulnerable to major depressive disorder (MDD) is their inability to effectively regulate negative mood when it arises. Investigating the neural underpinnings of adaptive emotion regulation and the extent to which such processes are compromised in MDD may be helpful in understanding the pathophysiology of depression. We report results from a functional magnetic resonance imaging study demonstrating left-lateralized activation in the prefrontal cortex (PFC) when downregulating negative affect in nondepressed individuals, whereas depressed individuals showed bilateral PFC activation. Furthermore, during an effortful affective reappraisal task, nondepressed individuals showed an inverse relationship between activation in left ventrolateral PFC and the amygdala that is mediated by the ventromedial PFC (VMPFC). No such relationship was found for depressed individuals, who instead show a positive association between VMPFC and amygdala. Pupil dilation data suggest that those depressed patients who expend more effort to reappraise negative stimuli are characterized by accentuated activation in the amygdala, insula, and thalamus, whereas nondepressed individuals exhibit the opposite pattern. These findings indicate that a key feature underlying the pathophysiology of major depression is the counterproductive engagement of right prefrontal cortex and the lack of engagement of left lateral-ventromedial prefrontal circuitry important for the downregulation of amygdala responses to negative stimuli.

Understanding the dimensional change card sort: Perspectives from task success and failure

Four experiments consider some of the circumstances under which children follow two different rule pairs when sorting cards. Previous research has repeatedly found that 3-year-olds encounter substantial difficulties implementing the second of two conflicting rule sets, despite their knowledge of these rules. One interpretation of this phenomenon [Cognitive Complexity and Control (CCC) theory] is that 3-year-olds have problems establishing an appropriate hierarchical ordering for rules. The present data suggest an alternative account of children's card sorting behaviour, according to which the cognitive salience of test card features may be more important than inflexibility with respect to rule representation.
