Full Text Available In view of the importance of certain problems relating to frit solubility in ceramic tile manufacture, a study was undertaken to determine how a set of different factors affect frit solubility. It was determined how the solubility of two frits was modified of the type of raw material used to make the frits and a series of variables relating to the glazes prepared from these frits. Relevant information was thus obtained regarding the industrial use of the frits, which is where the problems occur. The influence was specifically studied of milling time, suspension temperature, standing time, stirring intensity and the chemical composition of certain additives (binders and deflocculants on solubility. They were all found to substantially affect frit solobility, specially for certain elements (calcium, magnesium and cinc.

Dada la importancia que revisten algunos problemas relacionados con la solubilidad de fritas en el proceso de fabricación de baldosas cerámicas, se ha abordado la realización de un trabajo destinado a conocer la influencia que ejercen sobre aquella un conjunto de factores de diferente naturaleza. Se ha determinado cómo se modifica la solubilidad de dos fritas en función del tipo de materia prima empleada para fabricarlas y de una serie de variables relacionadas con los esmaltes que se preparan a partir de aquellas. De esta forma se ha obtenido información relevante desde el punto de vista del uso industrial que se hace de las fritas, que es donde aparecen los problemas a que se ha hecho referencia anteriormente. Concretamente se ha estudiado la influencia sobre la solubilidad del tiempo de molturación, la temperatura de la suspensión, el tiempo de reposo, la intensidad de la agitación y la composición química de algunos aditivos (ligantes y desfloculantes. Se ha constatado que todas ellas inciden sustancialmente en la propiedad estudiada, especialmente para algunos elementos (calcio, magnesio y cinc.

Full Text Available ABSTRACT The effect on soil productivity of harvesting forestry products deserved special attention in last years. Consequently, it is necessary to establish quantitative indices of environmental and economic impact for the different management stages. The decision of planting forestry trees is dependent on financial indicators; high costs may change investor decision. Maintaining soil nutrient stock as a baseline for productivity support may be an indicator of ecological sustainability; however, it can increase costs. Our objective was to answer the following: (i How each harvest scenario affect the nutrient stability of plantations? (ii Which of the alternative scenarios is of higher financial value at present? And (iii Does the present scenario of higher financial value persist if, for maintaining ecological sustainability, we conserve or replace the nutrients exported during harvest? We simulated different types of harvest and crop residue treatments in plantations of Eucalyptus grandis of 8 and 11 years old. Nutrient export in different scenarios was quantified and ecological stability indices -Plantation Stability Index (PEI-, and financial indices –Present Net Worth, Soil Expectation Value and Internal Rate of Return - were analyzed considering the cost of nitrogen replacement. The scenario of total harvest and residue burning gave losses of 491 and 369 kgN.ha-1 for 8 and 11 years rotation, respectively. PEI have shown that complete tree harvest and residue burning cause the highest ecological impact with index values superior to 2.5 (>0.5= instability; economic indices lowered when soil nutrients are recovered through fertilization inputs. Revenues reduction may affect the decision of planting commercial trees, alerting and stimulating to improve harvest practices at harvest and post-harvest stages.

Full Text Available En la Argentina, el negocio de producir semilla fiscalizada de soja presenta baja rentabilidad, por lo que es necesario un sistema de producción altamente eficiente para poder competir. Al respecto, no se ha evaluado la sensibilidad de algunos cultivares al retraso del momento de cosecha y al perjuicio provocado en esta operación, medido en términos de calidad de sus semillas. El objetivo de este trabajo fue evaluar la calidad fisiosanitaria de semillas de soja de diferentes cultivares en respuesta a tratamientos combinados de periodos de exposición al ambiente y niveles de daño mecánico en la cosecha, en condiciones locales de producción. Se trabajó con semillas de soja de cuatro cultivares con diferentes grados de deterioro ambiental, incidencia fúngica y efectos mecánicos. Se evaluó la calidad a través de ensayos de germinación, vigor, daño mecánico, contenido de humedad y sanidad. La respuesta de las variables fisiosanitarias a la acción mecánica fueron diferentes en los cultivares evaluados, evidenciándose disminución de la germinación y del vigor y en general un aumento en la incidencia fúngica. Sin embargo, estos efectos fueron menos marcados que los ocasionados por el factor periodo de exposición al ambiente.In Argentina, the business of certified soybean seed production shows underperformance; therefore, a highly efficient production system is necessary to be able to compete in this field. In this respect, factors affecting competitiveness such as the sensitivity of some cultivars to the delay in harvest time and to the damage resulting from this delay have not been evaluated in terms of seed quality. The objective of this study was to evaluate the physiosanitary quality of soybean seeds from different cultivars in response to combined treatments of environmental exposure and levels of mechanical damage at harvest in local production. Soybean seeds from four cultivars with varied degrees of environmental damage

Full Text Available El presente artículo aborda la utilización de la Tecnología de la Información (TI como factor competitivo en un Arreglo Productivo Local (APL Cosecha Metal-Mecánica en el estado de Río Grande del Sur, Brasil y tiene como objetivo buscar la comprensión de como el uso de la TI contribuye al aumento de la competitividad. Para alcanzar este objetivo, fue realizada una investigación en las empresas que componen el APL. Los resultados de la investigación indicaron que las empresas perciben la importancia del uso de la TI, pero que, en la práctica, su utilización es limitada, sobre todo tratándose de la planificación de la TI. Otro de los resultados que se encontró es que las empresas, aunque formen parte del APL, aún no colaboran entre sí, ya sea a través del cambio de informaciones, o a través de Sistemas de Información. Las principales recomendaciones ante estos resultados es que las empresas traten de actuar activamente para el fortalecimiento del APL. En lo que se refiere al uso de la TI se hace necesaria la planificación y la inversión en la adquisición de sistemas integrados para la mejor gerencia de las informaciones, lo cual contribuirá al aumento de la competitividad de las empresas que pertenecen al arreglo.

Mediante la exploración de los datos del X Censo Nacional de Población y el establecimiento de algunas medidas cuantitativas, en este artículo se busca establecer el logro educativo de la población de personas de origen indígena y afrodescendiente, en contraposición con la población mestiza (que denominamos acríticamente blanca y algunos elementos como los de la localización provincial y el de inserción temprana en el mundo del trabajo como factores de exclusión educativa. Siendo este estudio de corte exploratorio, se pretende que dé insumos prácticos y conceptuales para profundizar en la temática de la exclusión social y educativa. El análisis estadístico realizado ha permitido visualizar el hecho de que la identidad étnica y cultural, así como la localización geográfica (a escala provincial no son factores de exclusión educativa y social, sino que las explicaciones hay que buscarlas en la circularidad de la pobreza, que determina logros educativos bajos que influyen, a su vez, el acceso a puestos de trabajo de baja calificación. Este estudio sugiere que la inserción temprana en el mercado de trabajo es un factor clave de exclusión.

Se escogió una muestra de 195 pacientes, a los cuales se les realizó una laringectomía total en el Instituto Nacional de Oncología y Radiobiología, en el período comprendido entre enero de 1986 y diciembre de 1993. Esta complicación se presentó en el 59 % de los pacientes. La alta incidencia de ella parece estar en relación con la no sistematización de la profilaxis antibiótica. La sepsis resultó ser un factor favorecedor en la formación de la fístula, así como el tipo de cierre faríngeo, lo cual evidenció la superioridad del cierre mecánico de la faringe en relación con el cierre manual. La anemia posoperatoria resultó ser un importante factor predisponente en la formación de la fístulaA retrospective and descriptive study aimed at examining some factors predisposing the formation of pharyngo-cutaneous fistulae in laryngectome patients was conducted. A sample of 195 patients who had been performed a total laryngectomy at the National Oncology and Radiobiology Institute from January, 1986 to December, 1993 was chosen. This posoperative complication came out in 50 % of patients and its high incidence seems to be related to the non systematic use of antibiotic prophylasis. Sepsis was an influential factor for the formation of fistula as well as the pharyngeal closure, which showed that the mechanical pharynx closure is superior to the hand closure. The posoperative anemia turned to be an important predisposing factor in the formation of pharyngo-cutaneous fistulae

Full Text Available El cultivo de la variedad de platanera Gruesa, selección local de Dwarf Cavendish, ha experimentado un importante aumento en los últimos años en las Islas Canarias, tanto al aire libre como bajo invernadero. La eliminación de hojas, tras la floración, es una práctica habitual en los cultivos bajo invernadero. Asimismo es frecuente la pérdida de hojas por el efecto de los vientos en los cultivos al aire libre. El objetivo de este trabajo es evaluar, mediante simulación de pérdida foliar por daños mecánicos, la influencia que tiene la disminución de superficie foliar sobre el llenado y cosecha de la fruta en dicho cultivar. Para ello, cuatro meses antes de la cosecha se efectuaron cinco niveles de defoliación: 0%, 25%, 50%, 75% y 100%. Se valoran dos métodos diferentes de defoliación, eliminación de limbo foliar y tronchado de hojas con posterior corte de éstas. Se analizan y presentan datos morfológicos, fenológicos y productivos, así como valoración de la metodología empleada en este trabajo para la simulación de daños. A partir de un 25% de defoliado, equivalente a 7.5 hojas funcionales por planta, se detectaron diferencias significativas con las plantas testigos.

Full Text Available Las actuales modificaciones en el mundo del trabajo y en especial en las instituciones universitarias, han puesto de manifiesto nuevos riesgos de orden psicosocial que impactan no solo la salud física sino también la salud mental de los docentes, derivándose en el conocido síndrome de burnout. Se identificaron algunos factores de riesgo psicosocial intralaboral que propician el desarrollo y prevalencia del síndrome de burnout en estos profesionales de algunos países de América Latina como Colombia, Venezuela, Argentina y México. Se concluyó que ciertos aspectos propios de la organización del trabajo y de su realización tales como: multiplicidad de tareas, sobrecarga laboral, espacios inadecuados, falta de tiempo y de remuneración que compense los esfuerzos, son algunas de las principales fuentes de riesgos psicosociales que coadyuvan al posterior desarrollo y prevalencia del síndrome en esta población.

Full Text Available La descomposición de la materia orgánica, es un importante proceso que relaciona la dinámica de la vegetación con la dinámica del suelo. Regulando este proceso intervienen
factores bióticos y abióticos. Algunos autores mencionan que la temperatura es el factor climático más importante,
especialmente en condiciones muy húmedas; mientras que otros autores aseguran que es la humedad el factor climático más importante. Sin embargo, resulta claro que en las zonas templadas, la tasa de descomposición es más baja que en las zonas tropicales. También se han desarrollado modelos que
predicen el contenido de materia orgánica y nitrógeno en suelos superficiales, con base en informaciones sobre temperatura promedio anual y un "factor de humedad". Así
mismo otros han elaborado modelos que predicen la tasa de descomposición con base en el porcentaje de lignina contenido en el follaje. La evotranspiración actual anual, sin
embargo, presenta curvas de regresión más ajustadas al modelo de predicción, siendo el factor de mayor importancia.

El trovo verde. Poesía improvisada satírico-obscena en la fiesta de la cosecha

Full Text Available Harvest time has been since Upper Antiquity an exceptional occasion in peasant societies, giving rise to festive customs such as duels of improvised poetry in obscene tone and motif. In these duels, precepts of decency were momentarily removed. The historical and comparative research since the fescennini verses of Antiquity, through the pullas of the trovadores de repente of the Golden Age and other satirical genres, allows to link the priapic improvised poetry of the Alpujarra in both reaping and grape harvest contexts to a long popular tradition in which debates of burlesque verses were an entertainment associated with the nexus between fertility of earth and sexuality and with a sense of regeneration that has cathartic laugh. The survival of this burlesque and erotic register among the Alpujarra troubadours in certain festivals, coincidental in dates, spaces and actors with the traditional context of licenses during harvest time, suggests the reusing of these duels of inventiveness, in which participants play recalling a time when

Las cosechas han constituido desde antiguo un momento excepcional en las culturas campesinas y han propiciado costumbres festivas, como las luchas de poesías improvisadas de tono y temática obscena, en que se levantaba efímeramente el precepto del decoro. El rastreo histórico y comparativo desde los versos fesceninos de la Antigüedad, pasando por las pullas de los trovadores de repente en el Siglo de Oro y otros géneros satíricos, permite vincular el trovo priápico de la Alpujarra en contextos de siega, parva y vendimia, a una larga tradición popular en que las porfías de versos burlescos constituían un divertimento asociado al nexo de unión entre la fertilidad de la tierra y la sexualidad, así como al sentido regenerador de la risa catártica.

It is commonly believed that pregnancy is a time of good mental health. However it has been observed, until recently, that many pregnant women, above all in post partum period, manifest depressive symptoms like sadness, social withdrawal and lack of motivation. The consequences are enormous, for mother mental health and for the psychical development of the baby. It becomes therefore necessary to screening and to precociously intervene on these pathological conditions and thanks also to the suitable knowledge of the risk factors for the potential development of depression post partum.

Iorgulescu, A; Sandu, I; Turcu, F; Iordache, N

2013-03-15

Endoscopic retrograde cholangiopancreatography (ERCP) is a complex endoscopic technique that evolved from a diagnostic to a mainly therapeutic procedure. This was due to the identification of post-procedural complications that can follow both simple ERCP and that associated with the instrumentation of the biliary and pancreatic ductals. The identification of post ERCP complications in a proportion of 5 to 10% of cases, with a mortality rate of 0.33%, imposed their analysis and study of risk factors involved in their occurrence. The significance of post ERCP complications reveals the necessity of their avoidance by adopting additional measures if risk factors are identified. We have retrospectively analyzed 900 cases that underwent ERCP in the Surgery Department of "Sf. Ioan" Clinical Hospital in a period of 17 years. The complications of the procedure were studied. Among them, a special attention was given to post-ERCP acute pancreatitis (pERCP-AP), the most common complication that occurred in the study group. We also tried to find out and highlight the risk factors for this complication. ERCP is a relatively safe invasive procedure, yet it has complications (8% of cases), some of them potentially fatal (mortality 0.43%). The most common complications after ERCP are acute pancreatitis (3.7%), papillary bleeding (1.04%), retroperitoneal duodenal perforation (0.69%) and biliary septic complications like acute cholecystitis and cholangitis (1.21%). Acute pancreatitis is by far the most common complication. Risk factors for its occurrence are difficult sphincterotomy with precut use, failure of CBD desobstruction, pancreatic sphincterotomy, repeated injection of contrast in the pancreatic ductal system, dysfunction of the sphincter of Oddi and the absence of changes of chronic pancreatitis. When risk factors are identified, the patients' selection must be very strict and diagnostic ERCP should be avoided in favor of non-invasive diagnostic methods (MRI

The objective of this study was to find risk factors in pregnancy for post-traumatic stress and depression 1 month after childbirth. Furthermore, the relation between post-traumatic stress and depression was explored. A prospective longitudinal study. Pregnant women in Linköping and Kalmar, Sweden. A total of 1224 women were assessed in pregnancy, week 12-20 and 32, as well as 1 month postpartum. Post-traumatic stress and depression after delivery were assessed 1 month postpartum. Potential risk factors were assessed in early and late pregnancy. Variables measured during pregnancy were trait anxiety, depression, fear of childbirth, childbirth-related traumatic stress, stress coping capacity, social support, parity, educational level, age, gestation week, parity, educational level, civil status, previous psychological/psychiatric counselling, and previous experience of any traumatic events. Delivery mode was assessed from the medical records. Prevalence of post-traumatic stress (criteria A, B, C, D, E, and F according to DSM-IV) and depression (Beck's depression inventory). One month postpartum, 12 (1.3%) women had post-traumatic stress (met symptom criteria B, C, and D for post-traumatic stress disorder according to Diagnostic and statistical manual of mental disorders, 4th edition [DSM-IV]). The most important risk factors in pregnancy were depression in early pregnancy (OR=16.3), severe fear of childbirth (OR=6.2), and 'pre'-traumatic stress (in view of the forthcoming delivery) in late pregnancy (OR=12.5). The prevalence of depression was 5.6%. Post-traumatic stress and depression were positively related 1 month postpartum and were predicted by mainly the same factors. Risk factors for post-traumatic stress and depression after childbirth can be assessed in early pregnancy. Post-traumatic stress and depression also seem to share the same underlying vulnerability factors.

POST Traumatic Stress Disorder in Emergency Workers: Risk Factors and Treatment

Science.gov (United States)

Argentero, Piergiorgio; Dell'Olivo, Bianca; Setti, Ilaria

Post traumatic stress disorder (PTSD) are emergent phenomena resulting from exposure to a traumatic event that causes actual or threatened death or injury and produces intense fear, helplessness, or horror. In order to assess the role of different factors contributing to this kind of emergent phenomenon prevalence rates across gender, cultures, and samples exposed to different traumas are examined. Risk factors for PTSD, including pre-existing individual-based factors, features of the traumatic event, and post-trauma interventions are examined as well. Several characteristics of the trauma, related to cognitions, post-trauma social support and therapeutic interventions for PTSD are also considered. Further work is needed in order to analyze the inter-relationships among these factors and underlying mechanisms. The chaotic nature of traumatic processes, the multiple and interactive impacts on traumatic events require a comprehensive perspective aimed at planning effective interventions. Treatment outcome studies recommended the combined use of training and therapies as first-line treatment for PTSD.

Data collected included patient demographics, baseline visual acuity(VAand post-operative logMAR best corrected VA at 1y. Data analysis was performed with IBM SPSS Statistics Version 22.0. RESULTS: A total of 103 patients were included. The mean age was 51.2y. On multivariable analysis, each pre-operative positive deviation of 1 logMAR from a baseline VA of 0 logMAR was associated with a post-operative improvement of 0.859 logMAR(P0.001. Likewise, an attached macula pre-operatively was associated with a 0.374(P=0.003logMAR improvement post vitrectomy. Absence of iris neovascularisation and absence of post-operative complications were associated with a post vitrectomy improvement in logMAR by 1.126(P=0.001and 0.377(P=0.005respectively. Absence of long-acting intraocular tamponade was associated with a 0.302(P=0.010improvement of logMAR post vitrectomy.CONCLUSION: Factors associated with visual improvement after vitrectomy are poor pre-operative VA, an attached macula, absence of iris neovascularisation, absence of post-operative complications and abstaining from use of long-acting intraocular tamponade. A thorough understanding of the factors predicting visual improvement will facilitate decision-making in vitreoretinal surgery.

There is evidence that traumatic birth experiences are associated with psychological impairments. This study aimed to estimate the prevalence of childbirth-related post-traumatic stress symptoms and its obstetric and perinatal risk factors among a sample of Iranian women. This was a cross-sectional study carried out in Bushehr, Iran during a 3-months period from July to September 2009. Data were collected from all women attending eleven healthcare centers for postnatal care 6 to 8 weeks after childbirth. Those who had a traumatic delivery were identified and entered into the study. In order to assess childbirth-related post-traumatic stress, the Post-traumatic Symptom Scale-Interview (PSS-I) was administered. Data on demographic, obstetric and perinatal characteristics also were collected. Multivariate logistic regression was performed to examine the association between childbirth-related post-traumatic stress and demographic and obstetric and perinatal variables. In all, 400 women were initially evaluated. Of these, 218 women (54.5%) had a traumatic delivery and overall, 80 women (20%) were found to be suffering from post-partum post-traumatic stress disorder (PTSD). Multiple logistic regression analysis revealed that post-partum PTSD was associated with educational level, gestational age at delivery, number of prenatal care visits, pregnancy complications, pregnancy intervals, labor duration, and mode of delivery. The findings indicated that the prevalence of traumatic birth experiences and post-partum PTSD were relatively high among Iranian women. The findings also indicated that obstetric and perinatal variables were independently the most significant contributing factors to women's post-partum PTSD. It seems that a better perinatal care and supportive childbirth might help to reduce the burden of post-partum PTSD among this population.

The aim of this study was to investigate which psychological factors are related to post-stroke subjective cognitive complaints, taking into account the influence of demographic and stroke-related characteristics, cognitive deficits and emotional problems. In this cross-sectional study, 350 patients were assessed at 2 months post-stroke, using the Checklist for Cognitive and Emotional consequences following stroke (CLCE-24) to identify cognitive complaints. Psychological factors were: proactive coping, passive coping, self-efficacy, optimism, pessimism, extraversion, and neuroticism. Associations between CLCE-24 cognition score and psychological factors, emotional problems (depressive symptoms and anxiety), cognitive deficits, and demographic and stroke characteristics were examined using Spearman correlations and multiple regression analyses. Results showed that 2 months post-stroke, 270 patients (68.4%) reported at least one cognitive complaint. Age, sex, presence of recurrent stroke(s), comorbidity, cognitive deficits, depressive symptoms, anxiety, and all psychological factors were significantly associated with the CLCE-24 cognition score in bivariate analyses. Multiple regression analysis showed that psychological factors explained 34.7% of the variance of cognitive complaints independently, and 8.5% (p psychological factors, proactive coping was independently associated with cognitive complaints (p cognitive complaints. Because cognitive complaints are common after stroke and are associated with psychological factors, it is important to focus on these factors in rehabilitation programmes.

Full Text Available Background: Risk factors for post hemithyroidectomy (HT biochemical hypothyroidism (BH and its course are not well understood. The aim of the study was to look at the incidence, risk factors and the course of BH after HT Material and Methods: Longitudinal observational study at a tertiary care referral centre. Patients undergoing HT (Jan to Dec 2009, having a follow up for 2 years, with no history of head and neck radiation and euthyroid pre op status were included. Serum TSH, FT4, TPO Ab, Anti Tg Ab, FNAC and USG thyroid are performed pre operatively. Post operatively the residual thyroid volume was assessed using USG at 1 week. TSH was performed at one, three, six, twelve months after surgery. Statistical analysis: SPSS vs. 12 used and appropriate statistical tests applied Results: Patients (n=92 satisfied the inclusion criteria (14 males and 78 females. The mean age, duration of the goiter, TPO Ab and serum Anti Tg Ab levels were 38.58 ± 9.98 years, 35.08 ± 49.39 months, 43.87 ± 85.7 IU/mL and 2.65 ± 2.28 IU/mL respectively. BH was observed in 43.48% (n=40. Patients who had BH after HT were older, had significantly lower residual thyroid volume and smaller sized involved lobe. Patients with thyroiditis had a relative risk of 1.97 for post operative BH. At one year 23.33% (n=21 had BH. Conclusions: Post hemithyroidectomy BH is common in older patients with lesser amount of residual thyroid volume. 50% of these recover spontaneously within the first year after surgery necessitating monitoring of thyroxine replacement

Full Text Available Stroke is a major health problem world-wide and its burden has been rising in last few decades. Until now tissue plasminogen activator is only approved treatment for stroke. Angiogenesis plays a vital role for striatal neurogenesis after stroke. Administration of various growth factors in an early post ischemic phase, stimulate both angiogenesis and neurogenesis and lead to improved functional recovery after stroke. However vascular endothelial growth factors (VEGF is the most potent angiogenic factor for neurovascularization and neurogenesis in ischemic injury can be modulated in different ways and thus can be used as therapy in stroke. In response to the ischemic injury VEGF is released by endothelial cells through natural mechanism and leads to angiogenesis and vascularization. This release can also be up regulated by exogenous administration of Mesenchymal stem cells, by various physical therapy regimes and electroacupuncture, which further potentiate the efficacy of VEGF as therapy in post stroke recovery. Recent published literature was searched using PubMed and Google for the article reporting on methods of up regulation of VEGF and therapeutic potential of growth factors in stroke.

It is well recognized that patients with end stage renal diseases (ESRD) have hyper-plastic parathyroid glands. In most patients, a decrease in parathyroid hormone (PTH) occurs by about 1 year after renal transplantation. However, some renal transplant recipients continue to have elevated level of PTH. We prospectively evaluated 121 patients undergoing renal transplantation between August 2000 and 2002. The duration of dialysis, calcium (Ca), phosphorus (P), albumin, creatinine and iPTH levels were recorded prior to transplantation and three months and one year after transplantation. These 121 patients were on dialysis for an average period of 17.4 months prior to transplantation. An increase in the serum Ca and a decrease in serum P and iPTH level was seen in the patients after transplantation (P< 0.001). Hyperparathyroidism was in 12 (9.9%) and 7 (5.7%) patients three months and one year after transplantation respectively. Elderly patients and patients with longer duration on dialysis had an increased risk of developing post transplant hyperparathyroidism and hypercalcemia in the first year post transplant (P< 0.05). In conclusion age and duration on dialysis before transplantation seems to be important risk factors for post transplant hyperparathyroidism. (author)

Post-operative sleep disturbance, with suppression of rapid eye movement sleep and slow wave sleep followed by a subsequent rebound, seems to be related to the magnitude of trauma and thereby to the surgical stress response. In this context, cortisol, autonomic stimulation, and certain cytokines...... may lead to abnormal sleep. Furthermore, the environment, pain and the administration of analgesics seem to be important factors in the precipitation of sleep abnormalities. Post-operative sleep disturbance may contribute to the development of episodic hypoxaemia, haemodynamic instability and altered...... mental status, all of which have an influence on post-operative morbidity and mortality. Prevention or reduction of the post-operative sleep disturbance may be achieved by minimizing surgical trauma, changing the conventional nursing procedures, avoiding opioids and treating pain with non...

Post-partum weight retention (PWR) has been identified as a critical pathway for long-term overweight and obesity. In recent years, psychological factors have been demonstrated to play a key role in contributing to and maintaining PWR. Therefore, the aim of this study was to explore the relationship between post-partum psychological distress and PWR at 9 months, after controlling for maternal weight factors, sleep quality, sociocontextual influences, and maternal behaviours. Pregnant women (N = 126) completed a series of questionnaires at multiple time points from early pregnancy until 9 months post-partum. Hierarchical regression indicated that gestational weight gain, shorter duration (6 months or less) of breastfeeding, and post-partum body dissatisfaction at 3 and 6 months are associated with higher PWR at 9 months; stress, depression, and anxiety had minimal influence. Interventions aimed at preventing excessive PWR should specifically target the prevention of body dissatisfaction and excessive weight gain during pregnancy. What is already known on this subject? Post-partum weight retention (PWR) is a critical pathway for long-term overweight and obesity. Causes of PWR are complex and multifactorial. There is increasing evidence that psychological factors play a key role in predicting high PWR. What does this study add? Post-partum body dissatisfaction at 3 and 6 months is associated with PWR at 9 months post-birth. Post-partum depression, stress and anxiety have less influence on PWR at 9 months. Interventions aimed at preventing excessive PWR should target body dissatisfaction. © 2013 The British Psychological Society.

Post partum depression (PPD) is an important complication of child-bearing. It requires urgent interventions as it can have long-term adverse consequences if ignored, for both mother and child. If PPD has to be prevented by a public health intervention, the recognition and timely identification of its risk factors is must. We in this review have tried to synthesize the results of Asian studies examining the risk factors of PPD. Some risk factors, which are unique to Asian culture, have also been identified and discussed. We emphasize on early identification of these risk factors as most of these are modifiable and this can have significant implications in prevention of emergence of post partum depression, a serious health issue of Asian women.

The aim of the present study was to investigate the rate of post-tonsillectomy hemorrhage (PTH) in a single institution and to evaluate the clinical risk factors for PTH. We reviewed the records of 692 patients who underwent tonsillectomy (TE) at Yokohama Minami Kyosai Hospital in Japan. PTH grades were grouped into three categories according to the severity of the hemorrhagic episode: (I) minimal hemorrhage that stopped after noninvasive treatment, (II) hemorrhage requiring treatment with local anesthesia, and (III) hemorrhage requiring reoperation under general anesthesia in the operating room. Clinical risk factors such as sex, age (adults vs. children), TE indication, surgeon's skill level, operative time, ligature type, and duration of antibiotic administration for PTH were investigated. Among the 692 patients, 80 (11.6%) showed PTH, with primary and secondary hemorrhage accounting for 1.6% and 10.0%, respectively. A category III PTH was observed in 18 patients; thus, the overall risk of reoperation was 2.6%. The PTH episode most frequently occurred on postoperative days 5 and 6. The frequency of PTH was significantly higher in male patients and in adults (Pdefinition of PTH. Clinical risk factors for PTH were adult age and male gender. The surgeon's skill level was an additional risk factor for category III PTH. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Determining the labor factors associated with post-traumatic stress in uniformed workers in Medellin. A cross-sectional study was made of 124 uniformed workers aged 20 to 48 years-old. A survey was made using an adults' post-traumatic stress instrument which had been validated in Medellin. Statistical analysis was carried out. Post-traumatic stress disorder risk prevalence was 52.2 %. Multivariate analysis showed that the highest risk situations were those related to previous mental health diagnosis (PR=7.67), working schedule (4.24), violent episodes (PR=3.59) and community relationships (PR=2.73). A person's current labor situation seemed to be a risk factor for developing post-traumatic stress in the target population.

POST-STROKE COGNITIVE IMPAIRMENT – PHENOMENOLOGY AND PROGNOSTIC FACTORS

Maya Danovska

Full Text Available Stroke patients are at higher risk of developing cognitive impairment. Cognitive dysfunctions, especially progressive ones, worsen stroke prognosis and outcome. A longitudinal follow-up of cognitive disorders, however, is rendered difficult by their heterogeneity and the lack of definitions generally agreed upon. Stroke is a major cause of cognitive deficit. The identification of risk factors, clinical determinants and laboratory markers of post-stroke cognitive deficit may help detect patients at increased risk of cognitive deterioration, and prevent or delay the occurrence of post-stroke cognitive impairments. Though inflammatory processes have been implicated in the pathogenesis of stroke, their role in the complex pathophysiological mechanisms of post-stroke cognitive impairment is not completely understood. Evidence suggests that elevated serum C-reactive protein is associated with both the increased risk of stroke and post-stroke cognitive deficit. The hypothesis of a possible relationship between markers of systemic inflammation and cognitive dysfunctions raises the question of how rational the option of applying non-steroidal anti-inflammatory drugs in a proper therapeutic window will be, especially during the acute phase of stroke, to prevent cognitive decline and dementia.

The antecedents and consequences of maternal post-natal anxiety have received comparatively less attention than depression despite being one of the most frequently reported mental health difficulties experienced by parents following childbirth. The aim of this study was to extend emerging literature on post-natal anxiety by investigating the prevalence of maternal anxiety symptoms, and its relationship with parenting behaviours (i.e. warmth, hostility) and experiences (i.e. parenting efficacy and satisfaction) within the first post-natal year. The psychosocial risk factors for post-natal anxiety symptoms were also explored. A community sample of 224 Australian mothers of infants (aged 0-12 months) completed a self-report questionnaire. Mothers in the current sample reported significantly more symptoms of anxiety compared with a normative sample. Approximately 18% of mothers reported mild to extremely severe symptoms of anxiety, with a high proportion experiencing co-morbid depressive symptoms. Maternal anxiety was associated with low parenting warmth, involvement, efficacy and satisfaction, and high parenting hostility. Yet, co-morbid depression and anxiety was more strongly associated with these parenting behaviours and experiences than anxiety alone. A range of psychosocial risk factors (e.g. education, sleep, relationship quality) were associated with maternal post-natal anxiety symptoms, providing opportunities for early identification and targeted early intervention. © 2014 John Wiley & Sons Ltd.

Training department's role in human factor analysis during post-trip reviews

Goodman, D.

1987-01-01

Provide training is a frequent corrective action specified in a post-trip review report. This corrective action is most often decided upon by technical and operational staff, not training staff, without a detailed analysis of whether training can resolve the immediate problem or enhance employees' future performance. A more specific human factor or performance problem analysis would often reveal that training cannot impact or resolve the concern to avoid future occurrences. This human factor analysis is similar to Thomas Gilbert's Behavior Engineering Model (Human Competence, McGraw-Hill, 1978) or Robert Mager's/Peter Pipe's Performance Analysis (Analyzing Performance Problems, Pitman Learning, 1984). At Palo Verde Nuclear Generating Station, training analysts participate in post-trip reviews in order to conduct or provide input to this type of human factor and performance problem analysis. Their goal is to keep provide training out of corrective action statements unless training can in fact impact or resolve the problem. The analysts follow a plant specific logic diagram to identify human factors and to identify whether changes to the environment or to the person would best resolve the concern

BACKGROUND: Stroke can affect a person\\'s ability to drive, an important means of transportation in the developed world. AIMS: To determine percentage of patients and factors associated with return to driving post-stroke in a service with emphasis on driver assessment. METHODS: Retrospective study of patients discharged from the Stroke Service of our 470-bed teaching hospital from 1998 to 2002. RESULTS: Of 72 drivers pre-stroke, 54% recalled a driving assessment and 68% returned to driving. Younger patients (58.6 +\\/- 12.0 vs. 66.5 +\\/- 10.5, p = 0.008) with lower Modified Rankin Score (median 1 vs. 2, p = 0.0001) and normal cognition (55 vs. 43%, p = 0.45) were more likely to resume driving. More patients who were assessed returned to driving than those who were not (74 vs. 61%, p = 0.31). CONCLUSIONS: A relatively high level of return to driving can be achieved post-stroke with a pro-active approach to driver assessment and rehabilitation. A structured assessment and referral programme should be offered where appropriate.

Exposure to natural disasters has been associated with increased risk for various forms of psychopathology. Evidence indicates that socioeconomic status (SES) may be important for understanding post-disaster psychiatric distress; however, studies of SES-relevant factors in non-Western, disaster-exposed samples are lacking. The primary aim of the current study was to examine the role of pre-typhoon SES-relevant factors in relation to post-typhoon psychiatric symptoms among Vietnamese individuals exposed to Typhoon Xangsane. In 2006, Typhoon Xangsane disrupted a mental health needs assessment in Vietnam in which the Self Reporting Questionnaire-20 (SRQ-20), and the Demographic and Health Surveys Wealth Index, a measure of SES created for use in low-income countries, were administered pre-typhoon. The SRQ-20 was re-administered post-typhoon. Results of a linear mixed model indicated that the covariates of older age, female sex, and higher levels of pre-typhoon psychiatric symptoms were associated with higher levels of post-typhoon psychiatric symptoms. Analysis of SES indicators revealed that owning fewer consumer goods, having lower quality of household services, and having attained less education were associated with higher levels of post-typhoon symptoms, above and beyond the covariates, whereas quality of the household build, employment status, and insurance status were not related to post-typhoon psychiatric symptoms. Even after controlling for demographic characteristics and pre-typhoon psychiatric symptoms, certain SES factors uniquely predicted post-typhoon psychiatric distress. These SES characteristics may be useful for identifying individuals in developing countries who are in need of early intervention following disaster exposure.

INTRODUCTION Back pain during spaceflight has often been attributed to the lengthening of the spinal column due to the absence of gravity during both short and long-duration missions. Upon landing and re-adaptation to gravity, the spinal column reverts back to its original length thereby causing some individuals to experience pain and muscular spasms, while others experience no ill effects. With International Space Station (ISS) missions, cases of back pain and injury are more common post-flight, but little is known about the potential risk factors. Thus, the purpose of this project was to perform an initial evaluation of reported post-flight back pain and injury cases to relevant spaceflight risk factors in United States astronauts that have completed an ISS mission. METHODS All US astronauts who completed an ISS mission between Expeditions (EXP) 1 and 41 (2000-2015) were included in this evaluation. Forty-five astronauts (36 males and 9 females) completed 50 ISS missions during the study time period, as 5 astronauts completed 2 ISS missions. Researchers queried medical records of the 45 astronauts for occurrences of back pain and injury. A case was defined as any reported event of back pain or injury to the cervical, thoracic, lumbar, sacral, or coccyx spine regions. Data sources for the cases included the Flight Medicine Clinic's electronic medical record; Astronaut Strength, Conditioning and Rehabilitation electronic documentation; the Private Medical Conference tool; and the Space Medicine Operations Team records. Post-flight cases were classified as an early case if reported within 45 days of landing (R + 45) or a late case if reported from R + 46 to R + 365 days after landing (R + 1y). Risk factors in the astronaut population for back pain include age, sex, prior military service, and prior history of back pain. Additionally, spaceflight specific risk factors such as type of landing vehicle and onboard exercise countermeasures were included to evaluate their

It is important to evaluate the penetration of surface cracks in a Leak-Before-Break analysis. Because the stress intensity factors for surface cracks in pre/post penetration had not yet been analyzed, the authors carried three-dimensional boundary element analyses in order to obtain them. First, the authors developed the technique of nodal breakdown appropriate for cracks with short ligament length in a two-dimensional boundary element analysis. Next, analyses of stress intensity factor for surface cracks in pre/post penetration were carried out using the technique of nodal breakdown for cracks with short ligament length and the three-dimensional boundary element code BEM 3 D which was designed for a supercomputer.

Full Text Available With modern therapies and supportive care, survival rates of childhood cancer have increased considerably. However, there are long-term psychological sequelae of these treatments that may not manifest until pediatric survivors are into adulthood. The prevalence of post-traumatic stress disorder (PTSD in young adult survivors of childhood cancer ranges from 6.2% to 22%; associated risk factors are young age at the assessment, female gender, low education level and some disease-related factors. The aim of this study was to investigate, in adolescent and young adult (AYA survivors of childhood cancer, the incidence and severity of post-traumatic stress symptoms (PTSS, and to identify the risk factors and the associated post-traumatic growth (PTG index.Participants were 223 AYA cancer survivors recruited during follow-up visits in the Oncohematology Clinic of the Department of Child and Woman’s Health, University of Padua. Data were collected from self-report questionnaires on PTSS incidence, PTG mean score, perceived social support, and medical and socio-demographic factors. Ex-patients’ mean age at the assessment was 19.33 years (SD = 3.01, 15-25, 123 males and 100 females, with a mean of years off-therapy of 9.64 (SD=4.17. Most (52.5% had survived an hematological disorder and 47.5% a solid tumor when they were aged, on average, 8.02 years (SD=4.40.The main results indicated a moderate presence of clinical (≥9 symptoms: 9.4% and sub-clinical PTSS (6-8 symptoms: 11.2%, with the avoidance criterion most often encountered.

Post-partum depression is a common complication of women after childbirth. The objective of this study was to determine the prevalence of and factors associated with depressive symptoms among post-partum mothers attending a child immunization clinic at a maternity hospital in Kathmandu, Nepal. This cross-sectional study was conducted among 346 post-partum mothers at six to ten weeks after delivery using systematic random sampling. Mothers were interviewed using a semi-structured questionnaire. The Edinburgh Postnatal Depression Scale (EPDS) was used to screen for depressive symptoms. Logistic regression analysis was used to calculate the association of post-partum depressive symptoms with socio-demographic and maternal factors. The prevalence of post-partum depressive symptoms among mothers was 30%. Mothers aged 20 to 29 years were less likely to have depressive symptoms (adjusted odds ratio (aOR) = 0.40; 95% CI: 0.21-0.76) compared to older mothers. Similarly, mothers with a history of pregnancy-induced health problems were more likely to have depressive symptoms (aOR = 2.16; CI: 1.00-4.66) and subjective feelings of stress (aOR = 3.86; CI: 1.84-4.66) than mothers who did not. The number of post-partum mothers experiencing depressive symptoms was high; almost one-third of the participants reported having them. Pregnancy-induced health problems and subjective feelings of stress during pregnancy in the post-partum period were found to be associated with depressive symptoms among these women. Screening of depressive symptoms should be included in routine antenatal and postnatal care services for early identification and prevention.

Full Text Available Purpose: The magnitude of disability observed in strokesurvivors is believed to be dependent in part, on the severity of neurological deficits incurred. A s important but less well understood, is thecontribution of demographic, physical and environmental factors. The objective of this study was to establish what demographic, environmentaland physical factors influence functional independence post stroke. Method: Convenience sampling was used in the selection of subjects from four stroke outpatient public health facilities in the Gauteng Province of South Africa. The data were collected using a structured questionnaire. The analytical tools used included descriptive statistics to measure percentages and cross tabulations to measure the level of associations between functional independence and some of the demographic factors. The Barthel Index was computed to establish the degree of functional independence. Finally the influence of factors on functional independence was investigated using bivariate logistic regressions.Results: The results showed that younger patients (18 - 34 yrs may have a higher likelihood of functional independence compared to older patients at the time of discharge from hospital (18 - 34 years: Odds Ratio = 1. Patients without helpers were more likely to be functionally independent than those with a helper (p = 0.03. Involvement in household activities (p = 0.01, participation in community activities (p = 0.02 and bowel and bladder continence (p = 0.003 and p = 0.04 improved the likelihood of functional independence.Conclusion and im plications: Factors that influence functional independence post stroke are: age, bowel and bladder continence, the presence of a caregiver, participation in household and community activities. It is also of value to encourage patients to participate in household and community activities post stroke as well as being less dependent on helpers in an effort to attain functional independence post

Los mayores costos de producción del clavel estándar se asocian con la mano de obra que se utiliza en las labores del cultivo; el desbotone es una de las actividades que demanda mayor uso de mano de obra y tiempo. El objetivo del estudio fue determinar el efecto del desbotone en diferentes estadios de desarrollo del botón principal, sobre la producción y calidad en poscosecha del clavel estándar variedad Nelson en el primer pico de cosecha. Se evaluaron los estadios conocidos popularmente como botón ‘arveja’, ‘garbanzo’, ‘barril’, ‘estrella’, ‘bala’ y ‘punto de corte’. Las variables medidas incluyeron producción total a primera cosecha, grados de calidad y algunos criterios de clasificación en poscosecha. Se concluyó que el desbotone en los estadios evaluados no influye significativamente en la producción total del clavel en la primera cosecha. Sin embargo, en la clasificación por grados de calidad, se encontraron diferencias significativas: el desbotone en botón arveja’, ‘garbanzo’ y ‘barril’ mostró mayores promedios en el número de tallos grado ‘select’, mientras que el desbotone en botón ‘estrella’, ‘bala’ y ‘punto de corte’ reflejó mayores promedios para los grados ‘fancy’ estándar y nacional. El desbotone en diferentes estadios de desarrollo del botón principal afectó el número de tallos torcidos, sin aumentar significativamente el número de tallos débiles. El ensayo permitió definir que la etapa crítica para el desbotone son los estadios de desarrollo del botón principal previos al estadio ‘barril’, pues pasado este punto disminuye la calidad del producto.

Epilepsy is a frequent complication of central nervous system (CNS) infections. Post-infectious epilepsy is commonly refractory to medical treatment and plays a pivotal role for the poor long-term outcome of CNS infections. To provide an overview of clinical characteristics and risk factors of seizures associated with CNS infections. In addition, to summarize the state of the art of anticonvulsive treatment and the pre-surgical evaluation process in refractory cases. A comprehensive literature search for articles published between January 1970 and December 2011 was carried out. The occurrence of seizures during the acute course of meningitis, encephalitis and brain abscess is the main risk factor for the development of post-infectious epilepsy. There is a shortage of trials evaluating the efficacy of prophylactic and symptomatic treatment during the course of acute infection. Moreover, there are no randomized-controlled trials studying anticonvulsive drugs and their combinations for the management of post-infectious epilepsy. In a selected group of patients, however, medically refractory focal epilepsy is potentially curable by surgery. Further studies are required to improve the pathogenetic understanding of post-infectious epilepsy in order to develop preventive measures as well as to evaluate additional medical and surgical treatment strategies for the patients currently not considered for surgery. © 2012 The Author(s) European Journal of Neurology © 2012 EFNS.

Full Text Available Post-transplant erythrocytosis (PTE is characterized by persistently ele-vated hematocrit level 0 51%. This complication is reported to develop in 10-20% of renal allografts recipients, mostly 2 years after kidney transplantation. PTE is self-limited in 25% of the patients; however it may persist in patients with an increased susceptibility for thrombosis and potential fatal outcome. To evaluate the prevalence and risk factors of PTE in our center, we reviewed the records of 235 patients who received renal allografts from 1999 to 2004. Polycythemia was found in 45 (19% patients. There was no significant correlation of polycythemia and age, history of hypertension, diabetes, pre-transplant hematocrit level, pre-transplant history of transfusion, graft′s function, and source of kidney. A significantly higher proportion of PTE patients were males, patients with history of polycystic kidney disease, and patients with glomerulonephritis. We conclude that PTE is an important complication of kidney transplantation. There are several risk factors that should be addressed to prevent this complication.

In clinical practice, the mechanisms underlying chronic post-surgical pain (CPSP) remain insufficiently understood. The primary goals of this study were to determine the incidence of chronic pain after thoracic surgery and to identify possible risk factors associated with the development of chronic post-thoracotomy pain in Chinese patients. The secondary goal was to determine whether the difference between pre- and post-operative white blood cell (WBC) counts could predict the prevalence of CPSP after thoracotomy. The impact of chronic pain on daily life was also investigated. We contacted by phone 607 patients who had undergone thoracotomy at our hospital during the period February 2009 to May 2010. Statistical comparisons were made between patients with or without CPSP. were ultimately analyzed from 466 qualified patients. The overall incidence of CPSP was 64.5%. Difference between pre- and post-operative WBC counts differed significantly between patients with or without CPSP (P factor for the development of CPSP following thoracotomy (P factors for chronic pain included younger age (operative pain (P = 0.005) and the duration of chest tube drainage (P factoring surgical patients during peri-operative period. Besides, age, diabetes mellitus, acute post-operative pain, and duration of chest tube drainage may also play a role in chronic post-surgical pain occurrence.

Post-stroke delirium is a common problem in the care of stroke patients, and is associated with longer hospitalization, high short-term mortality, and an increased need for long-term care. Although post-stroke delirium occurs in approximately 10 ~ 30% of patients, little is known about the risk factors for post-stroke delirium in patients who experience acute stroke. A total of 576 consecutive patients who experienced ischemic stroke (mean age, 65.2 years; range, 23-93 years) were screened for delirium over a 2-year period in an acute stroke care unit of a tertiary referral hospital. We screened for delirium using the Confusion Assessment Method. Once delirium was suspected, we evaluated the symptoms using the Korean Version of the Delirium Rating Scale-Revised-98. Neurological deficits were assessed using the National Institutes of Health Stroke Scale at admission and discharge, and functional ability was assessed using the Barthel Index and modified Rankin Scale at discharge and 3 months after discharge. Thirty-eight (6.7%) patients with stroke developed delirium during admission to the acute stroke care unit. Patients with delirium were significantly older (70.6 vs. 64.9 years of age, P = .001) and smoked cigarettes more frequently (40% vs. 24%, P = .033) than patients without delirium. In terms of clinical features, the delirium group experienced a significantly higher rate of major hemispheric stroke (55% vs. 26%, P delirium were older age, history of cigarette smoking, and major hemispheric stroke. Abrupt cessation of cigarette smoking may be a risk factor for post-stroke delirium in ischemic stroke patients. The development of delirium after stroke is associated with worse outcome and longer hospitalization.

Post-traumatic stress disorder (PTSD) is one of the most prevalent long-term psychiatric diagnoses among survivors of severe acute respiratory syndrome (SARS). The objective of this study was to identify the predictors of chronic PTSD in SARS survivors. PTSD at 30 months after the SARS outbreak was assessed by the Structured Clinical Interview for the DSM-IV. Survivors' demographic data, medical information and psychosocial variables were collected for risk factor analysis. Multivariate logistic regression analysis showed that female gender as well as the presence of chronic medical illnesses diagnosed before the onset of SARS and avascular necrosis were independent predictors of PTSD at 30 months post-SARS. Associated factors included higher-chance external locus of control, higher functional disability and higher average pain intensity. The study of PTSD at 30 months post-SARS showed that the predictive value of acute medical variables may fade out. Our findings do not support some prior hypotheses that the use of high dose corticosteroids is protective against the development of PTSD. On the contrary, the adversity both before and after the SARS outbreak may be more important in hindering recovery from PTSD. The risk factor analysis can not only improve the detection of hidden psychiatric complications but also provide insight for the possible model of care delivery for the SARS survivors. With the complex interaction of the biopsychosocial challenges of SARS, an integrated multidisciplinary clinic setting may be a superior approach in the long-term management of complicated PTSD cases.

The objective of our study was to estimate the prevalence of the post-partum depressive symptomatology in a sample of Tunisian women, to study associated factors and to assess its relationship to quality of life. This is a prospective study carried out in two stages: during the first week (T1), then between sixth and eighth week post-partum (T2). Depressive symptomatology and quality of life were assessed respectively by the Edinburgh Postnatal Depression Scale and the World Health Organization Quality of Life scale. In the first stage, the prevalence of depressive symptomatology in the total sample (150 women) was 14.7% and was related to age above 35 years, low school level, personal psychiatric history, multiparity, caesarean delivery or forceps in the previous pregnancy and unplanned pregnancy. This prevalence was 19.8% among the 126 women reviewed in T2 and was correlated with the exaggerated sympathetic signs during pregnancy, namely perversion of taste and fatigue. Quality of life was strongly correlated with depressive symptoms in T1 and T2. Post-partum depressive symptoms were common in our sample and were correlated with quality of life. Therapeutic measures should be proposed for women with post-partum depressive symptoms and particularly with several risk factors in order to improve their quality of life.

Post-stroke depression (PSD, as a common complication of stroke, always obstructs the process of stroke rehabilitation. Accordingly, defining the risk factors associated with PSD has extraordinary importance. Although there have been many studies investigating the risk factors for PSD, the results are inconsistent.Objectives: The objectives of this study were to identify the risk factors for PSD by evidence-based medicine.Data sources: A systematic and comprehensive database search was performed of PubMed, Medline, CENTRAL, EMBASE.com, the Cochrane library and Web of Science for Literature, covering publications from January 1, 1998 to November 19, 2016.Study Selection: Studies on risk factors for PSD were identified, according to inclusion and exclusion criteria. The risk of bias tool, described in the Cochrane Handbook version 5.1.0, was used to assess the quality of each study. Meta-analysis was performed using RevMan 5.3 software.Results: Thirty-six studies were included for review. A history of mental illness was the highest ranking modifiable risk factor; other risk factors for PSD were female gender, age (<70 years, neuroticism, family history, severity of stroke, and level of handicap. Social support was a protective factor for PSD.Conclusion: There are many factors that have effects on PSD. The severity of stroke is an important factor in the occurrence of PSD. Mental history is a possible predictor of PSD. Prevention of PSD requires social and family participation.

Cognitive factors and post-partum depression: What is the influence of general personality traits, rumination, maternal self-esteem, and alexithymia?

OBJECTIVES: The objective was to assess the impact of cognitive factors on post-partum depression (PPD) symptoms. Because most of the literature data concern the immediate post-partum period or the first year post-partum, we notably sought to assess the longer term impact of cognitive factors on the symptoms of PPD. METHODS: Two studies were performed. In a pilot study, 1-month post-partum, 63 women filled out a sociodemographic information sheet and completed the abbreviated, revised Eysenck...

Using a social ecological model, this paper describes selected intra- and interpersonal factors that influence exercise behavior in women post hip fracture who participated in the Exercise Plus Program. Model testing of factors that influence exercise behavior at 2, 6 and 12 months post hip fracture was done. The full model hypothesized that demographic variables; cognitive, affective, physical and functional status; pain; fear of falling; social support for exercise, and exposure to the Exercise Plus Program would influence self-efficacy, outcome expectations, and stage of change both directly and indirectly influencing total time spent exercising. Two hundred and nine female hip fracture patients (age 81.0 +/- 6.9), the majority of whom were Caucasian (97%), participated in this study. The three predictive models tested across the 12 month recovery trajectory suggest that somewhat different factors may influence exercise over the recovery period and the models explained 8 to 21% of the variance in time spent exercising. To optimize exercise activity post hip fracture, older adults should be helped to realistically assess their self-efficacy and outcome expectations related to exercise, health care providers and friends/peers should be encouraged to reinforce the positive benefits of exercise post hip fracture, and fear of falling should be addressed throughout the entire hip fracture recovery trajectory.

Allogeneic hematopoietic stem cell transplantation is a successful treatment for hematologic malignancies and a variety of genetic and metabolic disorders. In the period following stem cell transplantation, the immune-compromised milieu allows opportunistic pathogens to thrive. Epstein-Barr virus-associated post-transplant lymphoproliferative disease can be a life-threatening complication for transplanted patients because of suppressed T-cell-mediated immunity. We analyzed possible risk factors associated with post-transplant lymphoproliferative disease in a cohort of over 1,000 patients. The incidence of post-transplant lymphoproliferative disease was 4%. Significant risk factors identified by multivariate analysis were: human leukocyte antigen-mismatch (PEpstein-Barr virus mismatch recipient-/donor+ (Pdisease grade II to IV (P=0.006), pre-transplant splenectomy (P=0.008) and infusion of mesenchymal stromal cells (P=0.015). The risk of post-transplant lymphoproliferative disease has increased in more recent years, from less than 2% before 1998 to more than 6% after 2011. Additionally, we show that long-term survival of patients with post-transplant lymphoproliferative disease is poor despite initial successful treatment. The 3-year survival rate among the 40 patients with post-transplant lymphoproliferative disease was 20% as opposed to 62% among patients without post-transplant lymphoproliferative disease (Pdisease after transplantation in need of pre-emptive measures.

The aim of this study was to understand factors that influence post-traumatic stress (PTS) in Korean forensic science investigators. A total of 111 forensic science investigators were recruited in Korea. PTS was measured using the tool modified by Choi (2001) from the original developed by Foa, Riggs, Dancu, and Rothbaum (1993) based on DSM-IV. Factors influencing PTS included demographic and job-related characteristics, emotional intelligence, and death anxiety. PTS scores were positively correlated with personality type, fatigue from work, and death anxiety. PTS scores were negatively correlated with length of career as a forensic science investigator and emotional intelligence. The factors that had the greatest influence on PTS were death anxiety, years spent as a forensic science investigator, personality type, emotional intelligence, fatigue, and homicide experience. The explanatory power of these six factors was 44.0%. Therefore, it is necessary to regularly evaluate the mental health of those who are vulnerable to PTS. Based on these results, various interventions could be implemented for promoting overall health of the forensic science investigators. Copyright © 2013. Published by Elsevier B.V.

Full Text Available Abstract Background Young maternal age has long been associated with higher infant mortality rates, but the role of socioeconomic factors in this association has been controversial. We sought to investigate the relationships between infant mortality (distinguishing neonatal from post-neonatal deaths, socioeconomic status and maternal age in a large, retrospective cohort study. Methods We conducted a population-based cohort study using linked birth-death certificate data for Missouri residents during 1997–1999. Infant mortality rates for all singleton births to adolescent women (12–17 years, n = 10,131; 18–19 years, n = 18,954 were compared to those for older women (20–35 years, n = 28,899. Logistic regression was used to estimate adjusted odds ratios (OR and 95% confidence intervals (CI for all potential associations. Results The risk of infant (OR 1.95, CI 1.54–2.48, neonatal (1.69, 1.24–2.31 and post-neonatal mortality (2.47, 1.70–3.59 were significantly higher for younger adolescent (12–17 years than older (20–34 years mothers. After adjusting for race, marital status, age-appropriate education level, parity, smoking status, prenatal care utilization, and poverty status (indicated by participation in WIC, food stamps or Medicaid, the risk of post-neonatal mortality (1.73, 1.14–2.64 but not neonatal mortality (1.43, 0.98–2.08 remained significant for younger adolescent mothers. There were no differences in neonatal or post-neonatal mortality risks for older adolescent (18–19 years mothers. Conclusion Socioeconomic factors may largely explain the increased neonatal mortality risk among younger adolescent mothers but not the increase in post-neonatal mortality risk.

Post-traumatic stress disorder (PTSD) is associated with negative impacts on physical health. Victims of a myocardial infarction (MI) who develop PTSD may be particularly affected by these impacts due to their cardiovascular vulnerability. Post-traumatic reactions in this population are not well known. To examine the prevalence of PTSD after MI and its risk factors, and to validate a prediction model for PTSD symptoms. Patients hospitalized for MI (n=477) were recruited in three hospitals. The Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, and questionnaires concerning PTSD symptoms and general measures were administered to patients during hospitalization and at one-month follow-up. Four per cent of the patients had PTSD and 12% had partial PTSD. The perception of a threat to life, the intensity of acute stress disorder and depression symptoms several days after the MI, a history of referral to a psychologist or psychiatrist, and female sex were risk factors for the intensity of PTSD symptoms in a sequential multiple regression analysis (R=0.634). The prediction model was validated by applying the regression equation to 48 participants who were not included in the initial regression (R=0.633). The risk factors for development of PTSD symptoms identified in the present study could be used to facilitate the detection of patients at risk for developing PTSD symptoms so they can later be offered psychological interventions as needed.

This study evaluated the factors associated with post-traumatic stress symptoms in Korean adolescents who lived in a disaster-affected community. A total of 1101 students attending secondary and high schools in Jindo, the location of the Sewol ferry disaster, were enrolled in a cross-sectional survey. The Child Report of Post-traumatic Symptoms (CROPS), the Center for Epidemiological Studies Depression Scale (CES-D), and the State Anxiety Inventory for Children (SAIC) were administered. Female gender, older children, poor academic achievement, and directly witnessing the rescue scene were associated with post-traumatic stress symptoms. The CES-D and SAIC scores of subjects with witness of the rescue were significantly higher than those of respondents without such experiences. The regression analysis revealed that directly witnessing the rescue scene was significantly associated with post-traumatic stress symptoms after adjusting for other variables. The results of this study suggest that witnessing the rescue scene following a disaster might be a risk factor for post-traumatic stress symptoms in adolescents in disaster-affected communities.

To evaluate the effectiveness of transjugular intrahepatic portosystemic shunt(TIPS) in the management of gastroesophageal variceal bleeding and predictive factors for long-term survival in patients with post-necrotic liver cirrhosis. A total of 49 patients with post-necrotic liver cirrhosis underwent TIPS over a recent three-year period. Forty-five had a history of hepatitis B viral infection, and four, of hepatitis C viral infection. In all patients, the indication for the procedure was variceal bleeding. Child-Pugh class was A in seven patients, B in 16 and C in 26 patients at the time of the last bleeding. The effectiveness of portal decompression and bleeding control was evaluated. Long-term survival was calculated by the Kaplan-Meier method and predictive factors were analyzed using the Wilcoxon test. The procedure was technically successful in all cases. The portosystemic pressure gradient decreased significantly from 21.4 ± 6.4 mmHg to 12.0 ± 5.1 mmHg(N=45). Active variceal bleeding was controlled in 34 of the 37 emergency patients. The total length of follow-up was from one day to three and a half years(mean : 383 ± 357 days). Rebleeding developed in 17 patients (35%). Hepatic encephalopathy, either newly developed or aggravated, occurred in 16 (32.7%). The thirty-day mortality rate was 20.4%, and the one-year survival rate was 63.8%. The significant predictive factors for poor prognosis were Child-Pugh class C and post-TIPS hepatic encephalopathy. TIPS is effective in portal decompression in the patients with variceal bleeding due to post-necrotic liver cirrhosis. The Child-Pugh classification and hepatic encephalopathy after TIPS are considered to be significant predictive factors for long-term survival

Function of the PHA-4/FOXA transcription factor during C. elegans post-embryonic development

Chen Di

2008-02-01

Full Text Available Abstract Background pha-4 encodes a forkhead box (FOX A transcription factor serving as the C. elegans pharynx organ identity factor during embryogenesis. Using Serial Analysis of Gene Expression (SAGE, comparison of gene expression profiles between growing stages animals and long-lived, developmentally diapaused dauer larvae revealed that pha-4 transcription is increased in the dauer stage. Results Knocking down pha-4 expression by RNAi during post-embryonic development showed that PHA-4 is essential for dauer recovery, gonad and vulva development. daf-16, which encodes a FOXO transcription factor regulated by insulin/IGF-1 signaling, shows overlapping expression patterns and a loss-of-function post-embryonic phenotype similar to that of pha-4 during dauer recovery. pha-4 RNAi and daf-16 mutations have additive effects on dauer recovery, suggesting these two regulators may function in parallel pathways. Gene expression studies using RT-PCR and GFP reporters showed that pha-4 transcription is elevated under starvation, and a conserved forkhead transcription factor binding site in the second intron of pha-4 is important for the neuronal expression. The vulval transcription of lag-2, which encodes a ligand for the LIN-12/Notch lateral signaling pathway, is inhibited by pha-4 RNAi, indicating that LAG-2 functions downstream of PHA-4 in vulva development. Conclusion Analysis of PHA-4 during post-embryonic development revealed previously unsuspected functions for this important transcriptional regulator in dauer recovery, and may help explain the network of transcriptional control integrating organogenesis with the decision between growth and developmental arrest at the dauer entry and exit stages.

Multiple factors contribute to elevated post-void residual urine volumes (PVR), but they may indicate detrusor underactivity (DU), especially in older women. The aim here was to examine factors associated with and prognostic significance of elevated PVR in a geriatric post-hip fracture assessment in a female population. Consecutive female hip fracture patients (n = 409) aged 65 years and older were included. PVR was measured by bladder scanner. PVR of 160 ml or more was deemed elevated. Age-adjusted univariate logistic regression analyses were conducted to examine the association of the domains of the comprehensive geriatric assessment (CGA) with elevated PVR. Cox proportional hazards model was used to determine the age-adjusted association of an elevated PVR with 1-year mortality. Of the patients, 64 (15.6%) had elevated PVR. Having urinary or fecal incontinence, difficulties in physical activities of daily living, malnutrition, poor performance on Timed Up and Go and Elderly Mobility Scale were significantly associated with elevated PVR. Difficulties in instrumental activities of daily living, renal dysfunction, constipation, polypharmacy, nocturia, cognitive impairment and depressive mood were not associated with elevated PVR. Elevated PVR significantly increased the risk of mortality 1 year post hip fracture. Elevated PVR is relatively common in older female hip fracture patients and associated with physical functioning, malnutrition and risk of mortality. Even though a causal relationship cannot be confirmed, the findings may suggest a relationship between DU and physical frailty. PVR deserves to be included in the CGA of frail older patients including women.

2011-01-01

Several epidemiological studies have reported that diabetes mellitus is a risk factor for hepatocellular carcinoma (HCC) in hepatitis C virus (HCV)-positive patients. However, it is unclear whether or not post-challenge hyperglycemia is a risk factor. The purpose of this study was to determine the association between post-challenge hyperglycemia and hepatocarcinogenesis in HCV-positive patients. A total of 203 HCV-RNA-positive subjects (108 males, mean age 54.3±10.8 years; 95 females, mean age 56.6±10.3 years; genotype 1b/2a/2b/3a: 152/38/12/1) who underwent liver biopsy and a 75-g oral glucose tolerance test, and who were treated with interferon (IFN) were enrolled in this study. None of the subjects had been treated with antidiabetic drugs. The subjects underwent ultrasonography and/or computed tomography every 6 months after the end of the IFN therapy. Thirteen patients, including one patient who achieved a sustained viral response (SVR) with IFN, developed HCC. On multivariate analysis, male sex, age >65 years, excessive alcohol consumption, non-SVR, liver steatosis area >5% in liver specimens, and 120-min post-challenge hyperglycemia were risk factors for the development of HCC. After matching subjects for sex, age, alcohol intake, and response to the IFN therapy, advanced fibrosis stages [hazard ratio (HR) 2.8], liver steatosis (HR 5.4), and 120-min post-challenge hyperglycemia (HR 4.9) were significant risk factors for the development of HCC. Furthermore, after matching for the fibrosis stage, liver steatosis (HR 5.7) and 120-min post-challenge hyperglycemia (HR 6.9) remained as significant factors for HCC development. Post-challenge hyperglycemia is an independent risk factor for HCC in HCV-positive patients. (author)

Factors affecting plant diversity during post-fire recovery and succession of mediterranean-climate shrublands in California, USA

Keeley, J.E.; Fotheringham, C.J.; Baer-Keeley, M.

2005-01-01

Plant community diversity, measured as species richness, is typically highest in the early post-fire years in California shrublands. However, this generalization is overly simplistic and the present study demonstrates that diversity is determined by a complex of temporal and spatial effects. Ninety sites distributed across southern California were studied for 5 years after a series of fires. Characteristics of the disturbance event, in this case fire severity, can alter post-fire diversity, both decreasing and increasing diversity, depending on life form. Spatial variability in resource availability is an important factor explaining patterns of diversity, and there is a complex interaction between landscape features and life form. Temporal variability in resource availability affects diversity, and the diversity peak in the immediate post-fire year (or two) appears to be driven by factors different from subsequent diversity peaks. Early post-fire diversity is influenced by life-history specialization, illustrated by species that spend the bulk of their life cycle as a dormant seed bank, which is then triggered to germinate by fire. Resource fluctuations, precipitation in particular, may be associated with subsequent post-fire diversity peaks. These later peaks in diversity comprise a flora that is compositionally different from the immediate post-fire flora, and their presence may be due to mass effects from population expansion of local populations in adjacent burned areas. ?? 2005 Blackwell Publishing Ltd.

To analyze pre-surgical predictive factors of post-surgical pain in patients undergoing hip or knee arthoplasty. A systematic literature review was performed. We defined a sensitive strategy on Medline, Embase and Cochrane Library up to May 2013. The inclusion criteria were: patients undertaking knee and/or hip arthroplasty, adults with moderate or severe pain (≥4 on a Visual Analog Scale) in whom predictive factors of post-surgical pain were evaluated before surgery. Systematic reviews, meta-analyses, controlled trials and observational studies were selected. We excluded animals and basic science articles, reviews of prosthesis, prosthesis due to fractures, patients with rheumatic diseases or studies with mixed population in which disaggregated data was not possible to obtain. A total 37 articles of moderate quality were selected. The articles included representative patients undergoing a knee or hip arthroplasty in our country; most of them were aged 60 years or above, with osteoarthritis, and with a high rate of obesity and comorbidities. We found great variability regarding the type of studies and predictive factors. There was a strong association between post-surgical pain and the following pre-surgical factors: female gender, low socio-economic status, higher pain, comorbidities, low back pain, poor functional status, and psychological factors (depression, anxiety or catastrophic pain). There are pre-surgical factors that might influence post-surgical pain in patients undergoing a knee or hip arthroplasty. Therefore, they should be taken into account when considering an arthroplasty. Copyright © 2014 Elsevier España, S.L.U. y Sociedad Española de Reumatología y Colegio Mexicano de Reumatología.

This paper presents an analysis of factors influencing job satisfaction in post-transition economies on the example of the Czech Republic. Our research shows that women reported higher levels of job satisfaction compared to men. Education proved to be statistically significant in one of three indicators of job satisfaction. Personal income and workplace relationships proved to be positively and significantly related to all the three indicators of job satisfaction. Most of the occupational dummies were significantly related to two out of three indicators of job satisfaction. In addition, we found that Czech entrepreneurs enjoy and value their job, which indicates strong self-selection for doing business in post-transition economies. However, human capital expressed by the level of education was significant factor for job satisfaction, meaning that well-educated people might not be satisfied with their jobs or feel that their education and experience are wasted in the market economy.

To evaluate the association between stent dwelling time and sepsis after ureteroscopy, and identify risk factors for sepsis in this setting. The prospectively collected database of a single institution was queried for all patients who underwent ureteroscopy for stone extraction between 2010 and 2016. Demographic, clinical, preoperative and operative data were collected. The primary study endpoint was sepsis within 48 h of ureteroscopy. Logistic regressions were performed to identify predictors of post-ureteroscopy sepsis in the ureteroscopy cohort and specifically in patients with prior stent insertion. Between October 2010 and April 2016, 1 256 patients underwent ureteroscopy for stone extraction. Risk factors for sepsis included prior stent placement, female gender and Charlson comorbidity index. A total of 601 patients had a ureteric stent inserted before the operation and were included in the study cohort, in which the median age was 56 years, 90 patients were women (30%), and 97 patients were treated for positive preoperative urine cultures (16.1%). Postoperative sepsis, Sepsis rates after stent dwelling times of 1, 2, 3 and >3 months were 1, 4.9, 5.5 and 9.2%, respectively. On multivariate analysis, stent dwelling time, stent insertion because of sepsis, and female gender were significantly associated with post-ureteroscopy sepsis in patients with prior stent placement. Patients who undergo ureteroscopy after ureteric stent insertion have a higher risk of postoperative sepsis. Prolonged stent dwelling time, sepsis as an indication for stent insertion, and female gender are independent risk factors. Stent placement should be considered cautiously, and if inserted, ureteroscopy should be performed within 1 month. © 2017 The Authors BJU International © 2017 BJU International Published by John Wiley & Sons Ltd.

Conflict and post-conflict communities in sub-Saharan Africa have a high under recognised problem of intimate partner violence (IPV). Part of the reason for this has been the limited data on IPV from conflict affected sub-Saharan Africa. This paper reports on the prevalence, risk factors and mental health consequences of IPV victimisation in both gender as seen in post-conflict eastern Uganda. A cross-sectional survey was carried out in two districts of eastern Uganda. The primary outcome of IPV victimisation was assessed using a modified Intimate Partner Violence assessment questionnaire of the American Congress of Obstetricians and Gynaecologists. The prevalence of any form of IPV victimisation (physical and/or sexual and/or psychological IPV) in this study was 43.7 % [95 % CI, 40.1-47.4 %], with no statistically significant difference between the two gender. The factors significantly associated with IPV victimisation were: sub-county (representing ecological factors), poverty, use of alcohol, and physical and sexual war torture experiences. The mental health problems associated with IPV victimisation were probable problem alcohol drinking, attempted suicide and probable major depressive disorder. In post-conflict eastern Uganda, in both gender, war torture was a risk factor for IPV victimisation and IPV victimisation was associated with mental health problems.

Full Text Available The elimination of burning practices in sugarcane harvest has led to more sustainable productive systems, with lower impact on the environment and on communities. The present paper is part of a study in which two sugarcane management systems were compared: (a one with sugarcane harvest residue kept on the ground (trash blanketing; and (b one without trash blanketing (burnt residue. Cultivar LCP 85-384 was planted in macro-plots in a commercial field in Albarracín, Tucumán, Argentina. A split-plot experimental design with three replications was used. Each plot had five 30 m-long rows. Two crop cycles (2006/2007 and 2007/2008, i.e. second and third ratoon, were evaluated. From the end of harvest onwards, residue amount (dry matter/ha and residue C/N relationship were determined periodically. At the beginning and at the end of each crop cycle, residue P and K contents were assessed. Residue left after harvest amounted to 12 and 16 tons of dry matter per hectare in the first and second evaluated crop cycles, respectively, but decreased significantly throughout these periods. Residue C/N relationship was over 100 in both crop cycles (117 and 101, respectively, but decreased significantly in their course. Reductions in both sugarcane residue and C/N relationship were correlated with days after harvest and accumulated thermal time (∑ mean daily air temperature. Trash initial C concentration was similar in both crop cycles and amounted to approximately 45%, whereas initial N concentration differed (0.4% and 0.6% in second and third ratoon, respectively. Residue decomposition contributed 3800 to 5700 kg of C, 7 to 50 kg of N and 45 to 40 kg of K per ha to the agro-ecosystem in both crop cycles studied.La eliminación de la quema durante la cosecha de la caña de azúcar llevó a la implementación de sistemas productivos más sustentables, con menos impacto ambiental y más amigables con las poblaciones vecinas.

Higher levels of parental stress have long-term effects on children's health and could lead to dysfunction in the parent-child interaction. Different background factors can be predictors of high parental stress. The aim of this study was to examine parental stress among Swedish women and identify different factors linked to women's parental stress. About 702 women were recruited to a clinical study and followed up six months after birth. Data were collected by two questionnaires, and 279 women completed the Swedish Parental Stress Questionnaire (SPSQ). Less than very good mental health and depressive symptoms after birth were strongly associated with parental stress, and the strongest association was found between post-partum depressive symptoms and high levels of stress in the subscale Incompetence. Multiparity was associated with high stress in two subscales, and lower level of education was a protective factor for stress in nearly all subscales. Depressive symptoms and perceived poor mental health post-partum are the most important factors related to high parental stress. The results point to the importance of identifying and supporting mothers with depressive symptoms, since these women have both mental illness and increased stress. © 2015 Nordic College of Caring Science.

Los frutos de tomate han sido considerados una fuente importante de AA “nutricionales” (vitaminas A, C y E y AA “fitoquímicos no nutritivos” (licopeno, flavonoides, flavonas y compuestos fenólicos totales, cuyo consumo está relacionado con su potencial antimutagénico y propiedades anticancerígenas. Las condiciones ambientales durante el cultivo como: intensidad de luz, pH del suelo, frecuencia de riego, tipo de fertilización, pueden afectar la composición química del fruto. Asimismo, durante la maduración del tomate, se inducen varios cambios metabólicos relacionados con la biosíntesis de compuestos, incluyendo el licopeno y otros carotenoides. También se ha demostrado que ciertas operaciones de manejo post cosecha y procesamiento del tomate (cortado, empacado y almacenado pueden alterar la concentración de micronutrientes (vitaminas y minerales y de compuestos AA. De acuerdo con los antecedentes mencionados, en la presente revisión se abordará la importancia de conocer los factores pre y post cosecha que afectan el contenido de AA en el tomate; asimismo, se destacará la estabilidad de los compuestos fitoquímicos contenidos en frutos sometidos a diferentes condiciones de procesamiento. Esta información resulta útil para la industria de los alimentos, además de fomentar el consumo de compuestos funcionales.

Full Text Available El hórreo asturiano es uno de los testimonios más importantes de la arquitectura en madera europea. Su estudio ha sido realizado desde perspectivas etnográficas, considerándose al hórreo como la manifestación cultural de una comunidad campesina de carácter igualitario y segmentario. En este artículo se propone una renovación interpretativa, con un nuevo protocolo de análisis que puede aplicarse al conjunto de la arquitectura tradicional. Consideramos que el hórreo constituye un documento histórico imprescindible y un componente básico de la cultura material. Por ello, su análisis puede acometerse desde disciplinas históricas propias de este enfoque (Arqueología, Etnoarqueología, Arqueología de la Arquitectura, Household Archaeology. En nuestro acercamiento concedemos mayor importancia a la diacronía, los contextos históricos y la influencia de las estructuras sociales de clase en el desarrollo de la cultura material. En este sentido, el estudio permite demostrar que el hórreo asturiano «estilo Villaviciosa» fue una creación de las elites rurales de los siglos XIV-XVI. Sus diseños respondieron a las necesidades del contexto histórico: enfriamiento climático, aumento de las cosechas señoriales, consolidación de las elites rurales y renovación de sus arquitecturas de poder. Como arquitectura de dignidad, su repertorio decorativo obedeció a temáticas cultas que transformaban al hórreo en una iglesia de la cosecha y expresaban la ideología de la nobleza.

Denis, Anne; Luminet, Olivier

2018-03-01

The objective was to assess the impact of cognitive factors on post-partum depression (PPD) symptoms. Because most of the literature data concern the immediate post-partum period or the first year post-partum, we notably sought to assess the longer term impact of cognitive factors on the symptoms of PPD. Two studies were performed. In a pilot study, 1-month post-partum, 63 women filled out a sociodemographic information sheet and completed the abbreviated, revised Eysenck Personality Questionnaire, the Ruminative Responses Scale, the Maternal Self-Report Inventory, and the Edinburgh Post-Natal Depression Scale. In the main study, 124 women additionally completed the Toronto Alexithymia Scale. The main study population was divided into 2 subgroups: women in the first year post-partum (n = 74) and those in the second year post-partum (n = 50). In the pilot study performed 1-month post-partum, brooding rumination and low self-esteem were significant predictors of the PPD symptom intensity. Neuroticism, brooding rumination, and low maternal self-esteem were also significant predictors of the PPD symptoms reported in the first year post-partum. Lastly, ruminative thoughts and alexithymia were significant predictors of the PPD symptoms reported in the second year post-partum. Our results suggest that alexithymia may be an important predictor of the incidence of this condition. The observation of differences in the PPD models as a function of the post-partum period may open up opportunities for developing novel PPD prevention/treatment programs.

Objective: To evaluate the prevalence and contributing factors causing post transplant erythrocytosis in renal transplant patients. Methods: This retrospective study was conducted on live related renal transplant patients at SIUT. The records of all transplant recipients transplanted between April 2008 and December 2008 and who had at least 24 months follow up were studied. Patients in whom haematocrit exceeded 51% and those who received treatment for it were classified into post transplant erythrocytosis group. Results: Out of 200 renal transplant patients who had functioning graft at the time of analysis, 40 (20%) developed post transplant erythrocytosis (HCT >51%) after a mean interval of 9.5+- 2.5 months. Patients with erythrocytosis were mostly males (95% in PTE group vs 73.75% in non PTE group) ,had a shorter period on dialysis before undergoing renal transplantation (9.28 months in PTE group vs 14.56 months in non PTE group) and had relatively better graft function at the onset of erythrocytosis as judged by serum creatinine (S. Creatinine of 1.06+-0.29 mg/dl in PTE group vs 1.37 +- 0.51 mg/dl in non PTE group). No thrombotic complications were observed. All patients with erythrocytosis were treated with enalapril (ACE inhibitors) and 28 out of 40 required phlebotomy in addition to ACE inhibitors. The mean HCT at the time of last follow up in treated patients was 48.61+-1.85%. Conclusion: Post transplant erythrocytosis generally occurs in male patients with good graft function, thrombotic complications are of rare occurrence and response to ACE inhibitors is good.

Smaller hippocampal volume has often been observed in patients with post-traumatic stress disorder (PTSD). However, there is no consensus whether this is a result of stress/trauma exposure, or constitutes a vulnerability factor for the development of PTSD. Second, it is unclear whether hippocampal volume normalizes with successful treatment of PTSD, or whether a smaller hippocampus is a risk factor for the persistence of PTSD. Magnetic resonance imaging (MRI) scans and clinical interviews were collected from 47 war veterans with PTSD, 25 healthy war veterans (combat controls) and 25 healthy non-military controls. All veterans were scanned a second time with a 6- to 8-month interval, during which PTSD patients received trauma-focused therapy. Based on post-treatment PTSD symptoms, patients were divided into a PTSD group who was in remission (n = 22) and a group in whom PTSD symptoms persisted (n = 22). MRI data were analysed with Freesurfer. Smaller left hippocampal volume was observed in PTSD patients compared with both control groups. Hippocampal volume of the combat controls did not differ from healthy controls. Second, pre- and post-treatment analyses of the PTSD patients and combat controls revealed reduced (left) hippocampal volume only in the persistent patients at both time points. Importantly, hippocampal volume did not change with treatment. Our findings suggest that a smaller (left) hippocampus is not the result of stress/trauma exposure. Furthermore, hippocampal volume does not increase with successful treatment. Instead, we demonstrate for the first time that a smaller (left) hippocampus constitutes a risk factor for the persistence of PTSD.

Purpose/Objective: Indications for post-prostatectomy radiation therapy are not well defined. We reviewed our experience treating post-prostatectomy patients with external beam irradiation to assess clinical and pathologic factors predictive of biochemical control. Materials and Methods: Between 1/87 and 3/93, 61 patients received post-operative tumor bed irradiation with a median dose of 59.4 Gy (50.4 - 68 Gy). Median follow-up was 4.1 years (7.6 months - 8.3 years) from irradiation. Patients were treated for the following reasons: 1) adjuvantly, within 6 months of surgery for extracapsular extension, seminal vesicle involvement, or positive surgical margins (n=38); 2) persistently elevated PSA post-operatively (n=2); 3) rising PSA >6 months after surgery (n=9); and 4) biopsy proven local recurrence (n=12). No patients had known nodal or metastatic disease. All patients had post-radiation PSA data available. Biochemical control was the endpoint studied using Kaplan-Meier life table analysis. Biochemical control was defined as the ability to maintain an undetectable PSA ( 4 and ≤1 0, >10 and ≤20, and > 20 ng/ml. The 3 year actuarial rates of biochemical control were 100% for group 1, 66.7% for group 2, 61.5% for group 3, and 28.6% for group 4. Pre-RT PSA values were also evaluated. Univariate Cox models indicated lower presurgical and pre-RT PSA values were predictive of biochemical control (p=0.017, p 6 months after surgery (group 3), the 3 year actuarial rate of biochemical control was 55.6%. The 3 year actuarial rate of biochemical control for patients treated for a biopsy proven recurrence (group 4) was 8.3%. By pair-wise log rank test, the rates of biochemical control were significantly different between groups 1 and 3 (p=0.036), groups 1 and 4 (p<0.001), and groups 3 and 4 (p=0.009). Conclusion: Biochemical control was achieved in approximately half of the patients treated with post-operative prostatic fossa irradiation. Elevated presurgical and pre

Colorectal cancer surgery is associated with a high incidence of post-operative infections, the outcome of which may be improved if diagnosed and treated early enough. We compared white blood cell (WBC) count, C-reactive protein (CRP), and procalcitonin (PCT) as predictors of post-operative infections and analyzed their impact on long-term survival. This retrospective study included 186 patients undergoing colorectal surgery. Post-operative values of WBC, CRP, and PCT were analyzed by the receiver operating characteristic (ROC) analysis. We followed infections 30 d after the surgery. A five-year survival was analyzed by Kaplan-Meier method and prognostic factors by Cox regression model. Fifty-five patients (29.5%) developed post-operative infection, the most frequent of which was surgical site infection (SSI). C-reactive protein on post-operative day three and PCT on post-operative day two demonstrated the highest diagnostic accuracy for infection (area under the curve [AUC] 0.739 and 0.735). C-reactive protein on post-operative day three was an independent predictor of infection. Five-year survival was higher in the non-infected group (70.8%), compared with the infected group (52.1%). The worst survival (40.9%) was identified in patients with organ/space SSI. Post-operative infection and tumor stage III-IV were independent predictors of a worse five-year survival. C-reactive protein on post-operative day three and PCT on post-operative day two may be early predictors of infection after colorectal cancer surgery. Post-operative infections in particular organ/space SSI have a negative impact on long-term survival.

Surgically implanted transmitters are a common method for tracking animal movements. Immediately following surgical implantation, animals pass through a critical recovery phase when behaviors may deviate from normal and the likelihood of individual survival may be reduced. Therefore, data collected during this period may be censored to minimize bias introduced by surgery-related behaviors or mortality. However, immediate post-release mortalities negate a sampling effort and reduce the amount of data potentially collected after the censoring period. Wildlife biologists should employ methods to support an animal’s survival through this period, but factors contributing to immediate post-release survival have not been formally assessed. We evaluated factors that potentially influenced the immediate post-release survival of 56 spectacled eiders (Somateria fischeri) marked with coelomically implanted satellite transmitters with percutaneous antennae in northern Alaska in 2010 and 2011. We modeled survival through the first 14 days following release and assessed the relative importance and effect of 15 covariates hypothesized to influence survival during this immediate post-release period. Estimated daily survival rate increased over the duration of the immediate post-release period; the probability of mortality was greatest within the first 5 days following release. Our top-ranking model included the effect of 2 blood analytes, pH and hematocrit, measured prior to surgical implantation of a transmitter. We found a positive response to pH; eiders exhibiting acidemia (low pH) prior to surgery were less likely to survive the immediate post-release period. We found a curvilinear response to hematocrit; eiders exhibiting extremely low or high pre-surgery hematocrit were also less likely to survive the immediate post-release period. In the interest of maximizing the survival of marked birds following release, hematological data obtained prior to surgical implantation of

There are limited data regarding blood transfusion following abdominoplasty, especially in post-bariatric surgery patients. The purpose of this study was to evaluate (1) the frequency and outcomes of blood transfusion in post-bariatric surgery patients undergoing abdominoplasty and (2) the predictive risk factors of blood transfusion in this patient population. Using the Nationwide Inpatient Sample database, the authors examined the clinical data of patients with a history of bariatric surgery who underwent abdominoplasty from 2007 to 2011 in the United States. A total of 20,130 post-bariatric surgery patients underwent abdominoplasty during this period. Overall, 1871 patients (9.3 percent) received blood transfusion. Chronic anemia patients had the highest rate of blood transfusion (25.6 percent). Post-bariatric surgery patients who received blood transfusion experienced a significantly higher complication rate (10.1 percent versus 4.8 percent; p blood transfusion. The blood transfusion rate in post-bariatric surgery abdominoplasty patients is not insignificant. Chronic anemia and congestive heart failure are the two major predictors of transfusion. Modifying risk factors such as anemia before abdominoplasty might significantly decrease the possibility of blood transfusion. Risk, III.

When developing maternity care services, it is important to know how psychosocial factors affect the course of post-partum depression (PPD), and how depressed mothers are treated. The aim of this study is to assess how adverse childhood experiences, poor present support and violence, and low socioeconomic status (SES) associate with PPD, specifically in new onset and recurrent post-partum depression. The second aim is to assess the treatment received for PPD. This is a cross-sectional study. The study group comprises 104 mothers with a current episode of PPD, and a control group of 104 mothers without an episode. The Structured Clinical Interview for DSM-IV Axis I Disorders was used for data collection. Psychosocial risk factors, treatment issues, and the course of depression were assessed with a structured self-report questionnaire. In age-adjusted multivariate analyses, adverse childhood experiences, a low level of present support in close relationships, and a poor SES were associated significantly with PPD. Childhood adversity was associated with both new onset and recurrent depression. Nevertheless, a low level of support and a poor SES were also associated with recurrent depression. A quarter of mothers with a major depressive episode in the post-partum period attended psychiatric services. In mothers with new onset depression, the proportion was only 5%. There is an urgent need to develop the diagnostics of depression in maternity care services. An awareness of psychosocial risk factors might help in this. More depressed mothers should be referred to psychiatric services.

Surgical procedures on obese patients are expected to have a high incidence of surgical site infection (SSI). The identification of pre-operative or early post-operative risk factors for SSI may help the surgeon to identify subjects in risk and adequately optimize their status. We conducted a study of the association of comorbidities and pre- and post-operative analytical variables with SSI following laparoscopic sleeve gastrectomy for the treatment of morbid obesity. We performed a prospective study of all morbidly obese patients undergoing laparoscopic sleeve gastrectomy as a bariatric procedure between 2007 and 2011. An association of clinical and analytical variables with SSI was investigated. The study included 40 patients with a mean pre-operative body mass index (BMI) of 51.2±7.9 kg/m(2). Surgical site infections appeared in three patients (7.5%), of whom two had an intra-abdominal abscess located in the left hypochondrium and the third had a superficial incisional SSI. Pre-operatively, a BMI >45 kg/m(2) (OR 8.7; p=0.008), restrictive disorders identified by pulmonary function tests (OR 10.0; p=0.012), a serum total protein concentration 30 mcg/dL (OR 13.0; p=0.003), and a mean corpuscular volume (MCV) operative SSI. Post-operatively, a serum glucose >128 mg/dL (OR 4.7; p=0.012) and hemoglobin operative anemia and hyperglycemia as risk factors for SSI. In these situations, the surgeon must be aware of and seek to control these risk factors.

Chemotherapy (CT) is the first priority treatment for advanced stage lung cancer. However, symptom distress, impaired ability to conduct daily activities, and post-CT care needs are potential side effects of CT. To explore the factors related to the care needs of post-chemotherapy lung cancer patients. A cross-sectional study was used. One hundred and twenty-one adult patients who had been diagnosed with advanced-stage lung cancer and who had undergone CT using the Platinum and Docetaxel doublet regimen were recruited from a medical center in southern Taiwan. The instruments used included a nursing care needs survey, symptoms distress scale, daily activity interference scale, and patient characteristics datasheet. Participants self-prioritized their emergency management, health consultation, and emotional support activities based on their perceived care needs. The top three post-CT symptoms in terms of severity were: fatigue, appetite change, and sleep disorder. Primary disruptions in daily activities during the post-CT period related to: holding social activities, work, and stair climbing. Significant and positive correlations were found among daily activity interference (r = .30, p needs. The regression model indicated daily activity interference as a predictor of care needs, accounting for 10.7% of the total variance. These results highlight the relationships among care needs, symptom distress, and daily activity interference in post-chemotherapy lung-cancer patients. The present study provides a reference for nursing care to reduce the symptom distress, to enhance the performance of daily activities, and to meet the care needs of lung-cancer patients.

In this study, our purpose was to examine whether personality and cognitive factors could be related to post-partum depression (PPD), mediated by anxiety, in Spanish women. Women were evaluated for personality and cognitive factors after the first trimester, for anxiety in the third trimester, and for PPD 4 months after childbirth. A structural equation model revealed that personality and cognitive factors were associated with anxiety and PPD as predictors. Neuroticism and extroversion proved to be the most relevant factors. Conscientiousness was associated with pregnancy anxiety. Pregnancy anxiety appeared as an independent predictor of PPD. The model presented here includes personality and cognitive and emotional factors as predictors of PPD. Comprehensive care for pregnant women should contemplate assessment and intervention on all these aspects. Special focus should be on cognitive factors and emotional regulation strategies, so as to minimize the risk of later development of emotional disorders during puerperal phases.

Model testing of factors that influence exercise behavior at 2, 6 and 12 months post hip fracture was done. The full model hypothesized that demographic variables; cognitive, affective, physical and functional status; pain; fear of falling; social support for exercise, and exposure to the Exercise Plus Program would influence self-efficacy, outcome expectations, and stage of change both directly and indirectly influencing total time spent exercising. Two hundred and nine female hip fracture patients (age 81.0 ± 6.9, the majority of whom were Caucasian (97%, participated in this study. The three predictive models tested across the 12 month recovery trajectory suggest that somewhat different factors may influence exercise over the recovery period and the models explained 8 to 21% of the variance in time spent exercising. To optimize exercise activity post hip fracture, older adults should be helped to realistically assess their self-efficacy and outcome expectations related to exercise, health care providers and friends/peers should be encouraged to reinforce the positive benefits of exercise post hip fracture, and fear of falling should be addressed throughout the entire hip fracture recovery trajectory

Deployment separation and reunifications are salient contexts that directly impact effective family functioning and parenting for military fathers. Yet, we know very little about determinants of post-deployed father involvement and effective parenting. The present study examined hypothesized risk and protective factors of observed parenting for 282 post-deployed fathers who served in the Army National Guard/Reserves. Pre-intervention data were employed from fathers participating in the After Deployment, Adaptive Parenting Tools (ADAPT) randomized control trial. Parenting practices were obtained from direct observation of father-child interaction and included measures of problem solving, harsh discipline, positive involvement, encouragement, and monitoring. Risk factors included combat exposure, negative life events, months deployed, and PTSD symptoms. Protective factors included education, income, dyadic adjustment, and social support. Results of a structural equation model predicting an effective parenting construct indicated that months deployed, income, and father age were most related to observed parenting, explaining 16% of the variance. We are aware of no other study utilizing direct parent-child observations of father’s parenting skills following overseas deployment. Implications for practice and preventive intervention are discussed. PMID:26213794

The Sewol ferry disaster caused national shock and grief in Korea. The present study examined the prevalence and associated factors of post-traumatic stress disorder (PTSD) symptoms among the surviving students 20 months after that disaster. This study was conducted using a cross-sectional design and a sample of 57 students (29 boys and 28 girls) who survived the Sewol ferry disaster. Data were collected using a questionnaire, including instruments that assessed psychological status. A generalized linear model using a log link and Poisson distribution was performed to identify factors associated with PTSD symptoms. The results showed that 26.3% of participants were classified in the clinical group by the Child Report of Post-traumatic Symptoms score. Based on a generalized linear model, Poisson distribution, and log link analyses, PTSD symptoms were positively correlated with the number of exposed traumatic events, peers and social support, peri-traumatic dissociation and post-traumatic negative beliefs, and emotional difficulties. On the other hand, PTSD symptoms were negatively correlated with psychological well-being, family cohesion, post-traumatic social support, receiving care at a psychiatry clinic, and female gender. This study uncovered risk and protective factors of PTSD in disaster-exposed adolescents. The implications of these findings are considered in relation to determining assessment and interventional strategies aimed at helping survivors following similar traumatic experiences. © 2018 The Korean Academy of Medical Sciences.

While studies have documented gender differences by histologic type among lung cancer patients, the effect of these differences on the health-related quality of life (HRQoL) of post-lobectomy lungcancer patients and related factors remain uncertain. This study examines gender-specific HRQoL and related factors in post-lobectomy lung-cancer patients. A cross-sectional study design was applied. A convenience sample of 231 post-lobectomy lungcancer patients was recruited from the thoracic surgery outpatient departments of two teaching hospitals in Taipei, Taiwan from March to December 2012. Patients performed a spirometry test and completed instruments that included a Beck Depression Inventory-II, an Interpersonal Support Evaluation List, and the symptom and function scales of the Quality of Life Questionnaire. Data analysis used descriptive statistics, including mean and standard deviations, frequency, and percentage values. Independent-sample Student's t-tests and multivariate analyses were used for comparative purposes. This study confirmed a significant gender effect on HRQoL and HRQoL-related factors such as marital status, religious affiliation, smoking status, histologic type, symptoms, pulmonary function, depression, and family support. Moreover, multivariate analysis found gender to be a significant determinant of the HRQoL aspects of physical functioning, emotional functioning, and cognitive functioning. Finally, results indicated that factors other than gender were also significant determinants of HRQoL. Gender impacts the HRQoL and related factors of postoperative lung-cancer patients. Therefore, gender should be considered in assessing and addressing the individual care needs of these patients in order to attain optimal treatment outcomes. Copyright © 2014 Elsevier Ltd.

Full Text Available   Background: Divorce is a complex, multidimensional concept and its direct and indirect impacts affects thousands of people in Iran each year. However, the concept of post-divorce adjustment in Iranian women has not been studied in detail. The aim of the present qualitative study was to determine the factors contributing to post-divorce adjustment in divorced women.  Methods: A qualitative research was carried out using grounded theory approach, followed by three phases of open coding, axial coding, and selective coding. The participants consisted of 21 divorced women who were selected using purposive sampling method. Semi-structured interviews were conducted and then interviews were recorded and transcribed for further analysis.    Results: A total of 21 divorced women participated in the current study. The majority of the participants were between 20-30 years old; they were between 17 to 30 years when they married. Also, most of the participants had bachelor’s degree (11 and most of them had a job (16. In the primary data coding, 35 open concepts were extracted. These concepts were then reduced into 32 secondary concepts. At the final stage, 6 main categories contributing to post-divorce adjustment were extracted including: (a demographics, (b interpersonal, (c attitudinal, (d relational, (e supportive, and (f coping strategies.  Conclusion: The present study emphasizes the value of lived experiences of divorced women. Based on the findings of our study, it is important to develop a solid support network and provide interventions targeting the quality of life in divorced women.

The identification of infrequent side-effects of clotting factor concentrates, undetected by clinical trials, is facilitated by post-marketing surveillance. We present a post-marketing surveillance study in which 97 patients with haemophilia A, attending three haemophilia centres, were treated over a median follow-up period of 284 days (range 1-1074), and a total follow-up period of 30,080 days, with a pasteurized immunoaffinity purified factor VIII concentrate (Monoclate-P, Armour, Collegeville, USA). 5216 infusions, using 10,527,000 units of Monoclate-P, were carried out, mostly for routine haemarthroses or prophylaxis. No new inhibitors were observed during the study. At the start of the study 60/97 were HIV seropositive, 67/97 HBs antibody positive, 12 HbsAb negative and the remainder HBsAb positive before the study period. 13/14 tested were HAV seropositive at the beginning of the study. One patient became HAV seropositive during the study period, an infection thought to be community acquired. No other seroconversions were observed. Only one mild transfusion reaction was observed. This study confirms the safety and efficacy of Monoclate-P. Post-marketing surveillance or nationally organized pharmaco-vigilance should be practiced more widely to enable identification of low-frequency side-effects of treatment.

To identify factors involved in the persistence of stress urinary incontinence (SUI) from pregnancy to 2 years post partum. In a longitudinal study at Donostia Hospital, San Sebastián, Spain, 458 primigravid women were recruited from April to October 2007. SUI was diagnosed via the 2002 International Continence Society definition. Severity was assessed via the Incontinence Severity Index, and impact on quality of life via the International Consultation on Incontinence Questionnaire. Means (Student t test and analysis of variance) and percentages (χ(2) and Fisher exact tests) were compared, and multiple logistic regression analysis was performed with variables that were significant or close to significant in a univariate analysis (Ppregnancy. Incontinence severity was slight or moderate in most cases and the impact on quality of life was low. A higher body mass index (BMI) in pregnant women at term was the only factor found to be associated with persistent SUI (odds ratio 1.19; 95% confidence interval 1.08-1.32). Higher BMI in pregnant women at term was an independent risk factor for the persistence of SUI from pregnancy to 2 years post partum.

Full Text Available Hybrid selection in maize (Zea mays L. over the decades has increased post-silking dry matter (PostDM and nitrogen (PostN accumulation, often with an accompanying increase in one or more N use efficiency (NUE metrics such as partial factor productivity (PFP, N conversion efficiency (NCE, and N internal efficiency (NIE. More certainty on the underlying mechanisms of how PostDM and PostN changes over time have contributed to NUE gains or losses in modern-era hybrids can only be realized by directly comparing hybrids of different eras in the context of production-system-relevant management systems. A two-year and two-location field study was conducted in Indiana with two N rates (55 and 220 kg N ha−1, three plant densities (54,000, 79,000, and 104,000 plants ha−1 and eight commercial hybrids that were released by a single seed company from 1967 to 2005. The main treatment effects of N rate, density, and hybrid dominated the PostDM and PostN responses, and there were no significant two-way or three-way interactions. Total dry matter at maturity gains averaged 80 kg ha−1 year−1 of hybrid release when averaged over locations, plant densities and N rates. Total N contents at maturity increased 0.68 kg ha−1 year−1, primarily due to annual increases in grain N content (0.8 kg ha−1 year−1. Post-silking N uptake rate increased 0.44 kg ha−1 year−1 for these era hybrids in more favorable production site-years. Slopes of grain N concentration increases per unit PostN gain were similar for all hybrids. Gains in average PFP over time were considerably higher at the low N rate (0.9 kg ha−1 year−1 than at the high N rate (0.3 kg kg−1 year−1. Hybrid gains in NIE were evident from 1967 to 1994, but not thereafter. The low N rate and higher plant densities also increased relative NIE and NCE values, but without hybrid interactions. There was no consistent trend of NIE or NCE gains in these hybrids primarily because grain and whole-plant N

Peri-anaesthetic complications in an equine referral hospital: Risk factors for post anaesthetic colic.

Science.gov (United States)

Jago, R C; Corletto, F; Wright, I M

2015-11-01

Peri-anaesthetic complications are relatively common in equine patients and further investigations are warranted to identify manageable risk factors. To report morbidity and mortality rates and identify associated risk factors for horses undergoing general anaesthesia, within a predominantly racing Thoroughbred (TB) population. Single centre retrospective observational study. Anaesthetic and case records of all horses ≥12 months old undergoing general anaesthesia at Newmarket Equine Hospital between August 2010 and April 2012 were analysed, excluding emergency abdominal/dystocia procedures or traumatology cases with cardiovascular compromise. Mortality and morbidity rates were calculated and described. Uni- and multivariable analyses were used to investigate the relationship between the principal complication, post anaesthetic colic (PAC) and risk factors. A total of 1067 anaesthetic records of 1021 horses were included in the study; of these, 702 horses (65.8%) were TB, 169 (15.8%) developed a complication within 7 days of general anaesthesia and 10 (0.94%) died as a result. The most prevalent morbidity was PAC, 111 horses (10.5%) developed colic within 7 days of general anaesthesia. Thoroughbred horses (odds ratio [OR] 2.93, 95% confidence interval [CI] 1.73-4.96) and horses receiving sodium benzylpenicillin (NaBP) (OR 2.77, 95% CI 1.69-4.50) were at increased risk of PAC. Thoroughbred racehorses were identified as at increased risk of PAC in this study and might benefit from more critical evaluation of post anaesthetic gastrointestinal function. An alternative to the administration of NaBP for prophylactic antimicrobial therapy needs to be further investigated if its role in PAC is confirmed by other studies. © 2015 EVJ Ltd.

The neuroprotective effect against spinal cord ischemia/reperfusion injury in rats exerted by delayed xenon post-conditioning is stronger than that produced by immediate xenon post-conditioning. However, the mechanisms underlying this process remain unclear. Activated microglia are the main inflammatory cell type in the nervous system. The release of pro-inflammatory factors following microglial activation can lead to spinal cord damage, and inhibition of microglial activation can relieve spinal cord ischemia/reperfusion injury. To investigate how xenon regulates microglial activation and the release of inflammatory factors, a rabbit model of spinal cord ischemia/reperfusion injury was induced by balloon occlusion of the infrarenal aorta. After establishment of the model, two interventions were given: (1) immediate xenon post-conditioning-after reperfusion, inhalation of 50% xenon for 1 hour, 50% N 2 /50%O 2 for 2 hours; (2) delayed xenon post-conditioning-after reperfusion, inhalation of 50% N 2 /50%O 2 for 2 hours, 50% xenon for 1 hour. At 4, 8, 24, 48 and 72 hours after reperfusion, hindlimb locomotor function was scored using the Jacobs locomotor scale. At 72 hours after reperfusion, interleukin 6 and interleukin 10 levels in the spinal cord of each group were measured using western blot assays. Iba1 levels were determined using immunohistochemistry and a western blot assay. The number of normal neurons at the injury site was quantified using hematoxylin-eosin staining. At 72 hours after reperfusion, delayed xenon post-conditioning remarkably enhanced hindlimb motor function, increased the number of normal neurons at the injury site, decreased Iba1 levels, and inhibited interleukin-6 and interleukin-10 levels in the spinal cord. Immediate xenon post-conditioning did not noticeably affect the above-mentioned indexes. These findings indicate that delayed xenon post-conditioning after spinal cord injury improves the recovery of neurological function by reducing

Post-partum depression (PPD) is the most prevalent mental problem associated with childbirth. The purpose of the present study was to determine the incidence of early PPD and possible relevant risk factors among women attending primary health centers in Mazandaran province, Iran for the first time. A longitudinal cohort study was conducted among 2279 eligible women during weeks 32-42 of pregnancy to determine bio-psycho-socio-cultural risk factors of depression at 2 weeks post-partum using the Iranian version of the Edinburgh Postnatal Depression Scale (EPDS). Univariate and hierarchical multiple logistic regression models were used for data analysis. Among 1,739 mothers whose EPDS scores were ≤ 12 during weeks 32-42 of gestation and at the follow-up study, the cumulative incidence rate of depression was 6.9% (120/1,739) at 2 weeks post-partum. In the multivariate model the factor that predicted depression symptomatology at 2 weeks post-partum was having psychiatric distress in pregnancy based on the General Health Questionnaire (GHQ) (OR = 1.06, (95% CI: 1.04-1.09), p = 0.001). The risk of PPD also lower in those with sufficient parenting skills (OR = 0.78 (95% CI: 0.69-0.88), p = 0.001), increased marital satisfaction (OR = 0.94 (95% CI: 0.9-0.99), p = 0.03), increased frequency of practicing rituals (OR = 0.94 (95% CI: 0.89-0.99), p = 0.004) and in those whose husbands had better education (OR = 0.03 (95% CI: 0.88-0.99), p = 0.04). The findings indicated that a combination of demographic, sociological, psychological and cultural risk factors can make mothers vulnerable to PPD.

Few studies on long-term functional outcome have been conducted in post-stroke patients in China. The objective of this study was to conduct a nationwide survey in China to investigate the 5-year prevalence of post-stroke disability and its correlation factors. A total of 893 patients with ischemic stroke were included. Demographic, clinical and neuro-imaging information were collected with standardized instruments that assessed stroke severity, depression, cognitive impairment, stroke recurrence and physical disability. Disability was assessed with the modified Ranking Score (mRS), of which a cutoff score ≥2 indicates disability. Statistical analysis included chi-square tests, two independent samples t-tests, Mann-Whitney U test and multiple logistic regression analysis. The frequency of disability in this study population was 45%. Multivariate analyses revealed that older age, lower education level, previous history of stroke, stroke severity at admission, depression, cognitive impairment at 3 months, and stroke recurrence within 5 years follow up were all significantly associated with post-stroke disability. The disability rate in 5-year post-stroke was high in Chinese patients. Treatment of depression, secondary prevention of stroke and rehabilitation may benefit disabled patients with stroke in China.

Post-Flight Back Pain Following International Space Station Missions: Evaluation of Spaceflight Risk Factors

Science.gov (United States)

Laughlin, Mitzi S.; Murray, Jocelyn D.; Wear, Mary L.; Van Baalen, Mary

2016-01-01

Back pain during spaceflight has often been attributed to the lengthening of the spinal column due to the absence of gravity during both short and long-duration missions. Upon landing and re-adaptation to gravity, the spinal column reverts back to its original length thereby causing some individuals to experience pain and muscular spasms, while others experience no ill effects. With International Space Station (ISS) missions, cases of back pain and injury are more common post-flight, but little is known about the potential risk factors.

However, there is little information available about its causes and methods of control. The effectiveness of L-cysteine (0.125, 0.25 and 0.5% in fresh-cut cherimoya harvested on two occasions (October and November and stored for 6 and 12 days at 0 °C was studied. In order to understand the biological basis of browning, polyphenol oxidase (PPO enzyme activity and total phenolic content in fresh-cut pieces were measured. Quality measurements and sensory analysis indicated that 0.5% L-cysteine was somewhat effective in reducing browning development, without affecting other quality attributes. In terms of physiological parameters, PPO activity did not show differences between mature (at harvest and ripe fruit (at processing in both harvest times, but cherimoya fruits picked in November presented lower PPO activity than fruit from October. In general, PPO activity and total phenolic content of L-cysteine treated fruits did not show consistent differences with untreated fruit at 6 or 12 days at 0 °C. PPO activity analyses demonstrated that PPO activity was higher in the outer part of cherimoya flesh compared to the middle or inner sector. These results would support the possibility of using L-cysteine as a postharvest treatment to reduce browning development in fresh-cut cherimoya.El desarrollo de pardeamiento es uno de los factores limitantes en la calidad de chirimoya (Annona cherimola Mill. precortada (fresh-cut.

This study examined the severity of post-traumatic stress and depressive disorders in Longmenshan adolescents after the 2013 Lushan earthquake, as well as relationships among earthquake-related exposure, post-earthquake negative factors, previous exposure to the 2008 Wenchuan earthquake, and level of earthquake impact (city). A cross-sectional survey was conducted among adolescents in Lushan (n = 1416), Baoxing (n = 1102) and Tianquan (n = 1265) at 3 years after the Lushan earthquake. Respondents were evaluated using the Earthquake Experience Scale, the Adolescent Self-rating Life Events Checklist (ASLEC), the Children's Revised Impact of Event Scale (CRIES-13), and the Depression Self-Rating Scale (KADS-6). High levels of post-traumatic stress and depression symptoms were found among adolescents in the most heavily affected cities, and these symptoms were more severe in respondents exposed to the 2008 earthquake. PTSD correlated most strongly with earthquake exposure, whereas depression correlated most strongly with psychosocial stressors following the event.

Full Text Available Aim: to assess the relationship between preand post-transplantation factors and degree of coronary artery lesion, reported by intravascular ultrasound study (IVUS in patients who underwent orthotopic heart transplantation (OHT surgery. Materials and methods. The study comprised of 27 patients who underwent OHT more than 2 years before. The age of patients was 46,8 ± 10,4 years old. All of them were preoperatively classified by HLA system. All patients received transthoracic echocardiography at terms of 1, 6, 12 and 24 months after OHT. Coronary angiography (CAG and IVUS were performed at 24 ± 6 months. Results. In CAG none of the patients showed angiographic signs of CA stenosis, but changes of various degrees were detected by IVUS. Results obtained by IVUS were clustered to select two groups with different degree of coronary artery lesion. The donor’s age in Group 2 was evidently higher compared to Group 1 (34,77 ± 1,03 and 40,00 ± 2,04 years, respectively, p = 0,043. Donor-recipient coincidence frequency was lower in group with significant CA lesion (by 2,36, р = 0,003. The number of cardiac surgeries performed prior to OHT was higher in Group 2 (by 2,8, р = 0,008. Post-transplant factor analysis showed that the number of diabetes mellitus (DM cases revealed after transplantation was more frequent in Group 2 (by 3,2 vs Group 1, р = 0,021. Conclusion. The degree of CA lesion according to IVUS at 24-month period after OTH was associated with several post-transplant factors, which were the presence of cardiac surgical interventions before transplantation, low HLA donor-recipient coincidence frequency, and donor’s age. The more significant CA lesion is, the more cases of DM after OHT occur.

In radiotherapy of pelvic cancers, the X-ray dose to be delivered to the tumour is limited by the tolerance of healthy surrounding tissue. In recent years, a number of serious complications of irradiation of pelvic organs were encountered. Modern radiotherapy necessitates the acceptance of a calculated risk of complications in order to achieve a better cure rate. To calculate these risks, one has to know the radiation dose-effect relationship of normal tissues. Of the normal tissues most at risk when treating pelvic tumours only the bowel is studied. In the literature regarding post-irradiation bowel complications, severe and mild complications are often mixed. In the present investigation the author concentrated on the group of patients with relatively mild symptoms. He studied the incidence and course of post-irradiation diarrhea in 196 patients treated for carcinoma of the uterine cervix or endometrium. The aims of the present study were: 1) to determine the incidence, course and prognostic significance of post-irradiation diarrhea; 2) to assess the influence of radiotherapy factors; 3) to study the relation of bile acid metabolism to post-irradiation diarrhea; 4) to investigate whether local factors (reservoir function) were primarily responsible.

Full Text Available Las características de la poesía de Héctor Viel Temperley han hecho de él un poeta de gran predicamento en el contexto literario argentino actual. En ella, la exaltación del cuerpo, del deporte, de la sensualidad y la sexualidad constituyen una peculiar forma de búsqueda de lo sagrado. En este sentido, la poesía del autor de Hospital Británico guarda similitudes con la inquietante lírica de William Blake. Aunque el tenor de la producción de Viel Temperley es diferente de la del inglés, hay en ambas una misma actitud de exaltación del cuerpo como vía de acceso a lo sagrado. En el presente trabajo, abordaré algunos textos de ambos autores como muestras de una mística del cuerpo.

Post-infectious fatigue syndrome (PIFS), also known as post-viral fatigue syndrome, is a complex condition resulting in physical, cognitive, emotional, neurological, vocational and/or role performance disabilities in varying degrees that changes over time. The needs for health care resources are high, and costly, as is the economic burden on the affected individuals. Many factors may impact the trajectory, and frequently PIFS develops into a chronic condition. Health professionals lack understanding and knowledge, which results in delayed diagnosis, lack of recognition, appropriate treatment, support and practical help. The aim of our study was to explore, from the perspective of persons who had lived with PIFS for four years following an outbreak of Giardia l. induced enteritis, factors that may have impacted their illness trajectory and how these factors had played a role during different phases. In this retrospective exploratory qualitative study a group of 26 affected adults between 26 and 59 years old were selected for in-depth interviews. A maximum variation sample was recruited from a physician-diagnosed cohort of persons with PIFS enrolled at a tertiary outpatient fatigue clinic. The interviews were audio-recorded, transcribed verbatim and subjected to qualitative content analysis. Unhelpful and helpful factors were associated with the healthcare system, health professionals and the affected persons were experienced as having an impact on the trajectory. External impacting factors which are related to the health care system, providers and the social security system are misdiagnosis, trivialization of symptoms, unhelpful advice, delayed diagnosis and lack of appropriate help. Internal impacting factors related to the affected individuals were lack of knowledge, overestimating functional capacity, assuming the condition will pass, ignoring body signals and denial. A model of impacting factors in each phase of the trajectory is presented. Unmet needs may

Parental Factors Associated with Child Post-traumatic Stress Following Injury: A Consideration of Intervention Targets

Anna E. Wise

2017-08-01

Full Text Available Post-traumatic stress disorder (PTSD symptoms are relatively common following pediatric traumatic injury and are related to poor long-term child outcomes. However, due to concerns regarding the efficacy of early child preventive interventions, and difficulty intervening with injured and medicated children soon after the event, it is not feasible to provide early psychological interventions to children exposed to traumatic injury. Parental PTSD symptoms and reactions to the child’s traumatic injury impact child outcomes and provide potential targets for early intervention to reduce child symptom development without involving the child. The authors conducted a review of the literature using Psycinfo and Pubmed research databases (publication years = 1990–2017 and identified 65 published studies relevant to the topic of the review. The present review considers parent factors [parenting styles, parental post-traumatic pathology (PTS, adaptive and maladaptive coping strategies, and communication regarding the traumatic injury] and their impact on child PTS. We focus specifically on factors amenable to intervention. We further review moderators of these relationships (e.g., child age and gender, parent gender and conclude that it is unlikely that a one-size-fits-all approach to treatment will be successful. Rather, it is necessary to consider the age and gender of parent child dyads in designing and providing targeted interventions to families following the traumatic injury of a child.

Full Text Available Abstract Background Few studies have focused on the differences between persons who are recovered after whiplash injury and those who suffer from persistent disability. The primary aim of this study was therefore to examine differences in symptoms, psychological factors and life satisfaction between subjects classified as recovered and those with persistent disability five years after whiplash injury based on the Neck Disability Index (NDI. Methods A set of questionnaires was answered by 158 persons (75 men, 83 women to assess disability (NDI, pain intensity (VAS, whiplash-related symptoms (Rivermead Post-Concussion Symptoms Questionnaire, RPQ, post-traumatic stress (Impact of Event Scale, IES, depression (Beck's depression inventory, BDI and life satisfaction (LiSat-11. The participants were divided into three groups based on the results of the NDI: recovered (34.8%, mild disability (37.3% and moderate/severe disability (27.3%. Results The moderate/severe group reported significantly higher VAS, BDI and IES scores and lower level of physical health and psychological health compared to the mild and the recovered groups. Less significant differences were reported between the mild and the recovered groups. Conclusions The group with the highest disability score reported most health problems with pain, symptoms, depression, post-traumatic stress and decreased life satisfaction. These findings indicate that classifying these subjects into subgroups based on disability levels makes it possible to optimize the management and treatment after whiplash injury.

Full Text Available La creciente atención que los problemas medioambientales suscitan entre un amplio sector de la sociedad, está produciendo una reacción en las empresas tanto por lo que a la adopción de sistemas de gestión medioambiental respecta como en el incremento de información medioambiental comunicada al exterior. A partir de los informes anuales de una muestra de 56 empresas correspondientes al periodo 1995-1998, el presente trabajo investiga algunos factores determinantes de las empresas que divulgan este tipo de información. Para ello, se procede a la estimación de un modelo de regresión lineal de un índice de información medioambiental sobre tres grupos de variables independientes. Los resultados obtenidos, coincidentes con los de la mayoría de estudios llevados a cabo al respecto, señalan que el tamaño, junto con la pertenencia a sectores específicos, resultan las variables más asociadas con el índice, mientras que no aparece relación alguna en el grupo de variables representativas de la evolución financiera de la compañía. The increasing awareness of corporate environmental problems among a large sector of society is bringing about reactions in companies, not only in terms of the adoption of environmental management systems but also in the inclusion in environmental information communicated publicly. Drawing on a sample of annual reports from 56 Spanish companies during the period 1995-1998, this paper seeks to identify certain factors causing this information to be disclosed. It constructs a linear regression model of an environmental information index using three groups of independent variables. The results obtained are consistent with the majority of studies in this area, with company size and industry being the variables most closely associated with the index, while no statistical link was found with variables representing financial development.

Childbirth might be a traumatic event for some women. This study was conducted with the objective of investigating the prevalence of Post-Traumatic Stress Disorder (PTSD) following childbirth. The study was designed using a descriptive correlation scheme. The participants were selected from the women referred to the healthcare centers affiliated with Zahedan University of Medical Sciences, Zahedan, Iran. Personal interviews were conducted with 600 women who were 6-8 weeks postpartum and had been undergone to this center for postpartum and child care. One hundred and three (17. 2%) women had symptoms of PTSD following childbirth based on the PTSD Symptom Scale (PSS). The results of logistic regression analysis revealed a significant correlation between maternal occupation (P = 0.01), depression level (P childbirth. PTSD from childbirth occurs in some women. Early identification of risk factors should lead to early therapeutic intervention in the mothers at risk of PTSD.

The goal of the current study is to examine the role of poor migration planning as a moderator for the effects of two post-migration factors, namely acculturation stress and quality of life, on symptoms of depression. Using a random sample of 347 Hong Kong new migrants from a 1-year longitudinal study, we used multiple regression analyses to examine both the direct and interaction effects of poorly planned migration, acculturation stress, and quality of life on depressive symptoms. Although poorly planned migration did not predict depressive symptoms at 1-year follow-up, it did exacerbate the detrimental effect of the two post-migration factors, namely high stress or low quality of life (both also measured at baseline) on depressive symptoms at this stage. Our results indicate that preventive measures must be developed for new immigrants in Hong Kong, especially for those who were not well prepared for migration.

Among the major complications of transsphenoidal surgery, less attention has been given to severe postoperative epistaxis, which can lead to devastating consequences. In this study, we reviewed 551 consecutive patients treated over a 4 year period by the senior author to evaluate the incidence, risk factors, etiology and management of immediate and delayed post-transsphenoidal epistaxis. Eighteen patients (3.3%) developed significant postoperative epistaxis - six immediately and 12 delayed (mean postoperative day 10.8). Fourteen patients harbored macroadenomas (78%) and 11 of 18 (61.1%) had complex nasal/sphenoid anatomy. In the immediate epistaxis group, 33% had acute postoperative hypertension. In the delayed group, one had an anterior ethmoidal pseudoaneurysm, and one had restarted anticoagulation on postoperative day 3. We treated the immediate epistaxis group with bedside nasal packing followed by operative re-exploration if conservative measures were unsuccessful. The delayed group underwent bedside nasal hemostasis; if unsuccessful, angiographic embolization was performed. After definitive treatment, no patients had recurrent epistaxis.

Lack of awareness of risk factors and symptoms for cancer may lead to late diagnosis and poor prognosis. We assessed community awareness about cervical cancer risk factors and symptoms and perceptions about prevention and cure of cervical cancer in order to contribute data to inform interventions to improve cervical cancer survival. Cross-sectional population-based survey. We conducted this study in Gulu, a post-conflict district in Uganda in 2012. The sample included 448 persons aged 18 years and above, selected through a multi-stage stratified cluster sampling process. We collected data using a pretested structured questionnaire. Logistic regressions were used to determine magnitudes of associations between socio-demographic and outcome variables. Most participants (444/448) had heard about cervical cancer. Known risk factors including multiple sexual partners, human papillomavirus infection, and early onset of sexual activity, were recognized by 88%, 82%, and 78% of respondents respectively. 63% of participants believed that prolonged use of family planning pills and injections caused cervical cancer. The majority of participants recognized symptoms of cervical cancer including inter-menstrual bleeding (85%), post-menopausal bleeding (84%), and offensive vaginal discharge (83%). 70% of participants believed that cervical cancer is preventable and 92% believed that it could be cured if diagnosed at an early stage. Recognition of cervical cancer risk factors and symptoms was high among study participants. Targeted interventions including increasing availability of HPV vaccination, population-based cervical screening and diagnostic services can translate high awareness into actual benefits. © 2015 The Authors.

Almost all studies on post-ERCP pancreatitis (PEP) have mainly involved patients with biliary diseases rather than chronic pancreatitis (CP), and the concept that CP seems to be a protective factor associated with PEP has not been studied in detail. The aim of this study was to determine the incidence of PEP in patients with CP at different clinical stages and to identify the predictive and protective factors of PEP in a large cohort. In this observational cohort study, medical records of patients with CP (CP group) and biliary diseases (BD group) in a tertiary hospital from January 2011 to May 2015 were examined. The difference in the incidence of PEP between CP group and BD group and the risk of PEP at different clinical stages of CP were calculated by the χ 2 test or the Fisher exact test. The predictive and protective factors for PEP were investigated by univariate and multivariate analysis. In total, 2028 ERCP procedures were performed in 1301 patients with CP and 2000 procedures in 1655 patients with BD. The overall incidence of PEP in CP group (4.5%) was similar to that in the BD group (4.8%; P = .747). However, CP patients had significantly lower rates of moderate and severe attacks (0% vs 1.3%, P pancreatitis, and prior PEP were independent risk factors of PEP, whereas extracorporeal shock wave lithotripsy was a protective factor. Compared with BD patients, CP patients had similar incidence of PEP overall but lower grades of severity. The incidence of PEP in CP patients decreased significantly with disease progression.

Full Text Available El propósito de este artículo es presentar algunos elementos sobre la teoría de los economistas clásicos con relación al empleo y confrontar sus ideas con lo que dentro del pensamiento económico se ha denominado como la moderna teoría del empleo: La versión Keynesiana. Es decir, se pretende retomar algunos de los argumentos de los autores clásicos en lo referente a la teoría del empleo, tratando sobre todo de establecer las similitudes y las diferencias entre dichas teorías y la concepción keynesiana, sin ninguna pretensión de originalidad de mi parte, sino más bien con el propósito de hacer una reflexión frente al tema del empleo, tan pertinente y a la vez preocupante, no solo para los economistas, sino para profesionales de diferentes disciplinas. El artículo hace referencia a los fundamentos principales que definen el mercado de trabajo y el problema del desempleo presentando un contraste entre la corriente de pensamiento ortodoxa y la teoría keynesiana. Se concluye que la teoría general no es la única ni la más completa argumentación del desempleo tal y como se presenta en la economía en la actualidad, pero tiene el mérito de haber brindado una explicación y alternativas de solución al flagelo del desempleo vivido en Estados Unidos en los años treinta del siglo pasado.

The objectives of this study were to characterize 60-d outcomes after treatment of mild (abnormal milk) and moderate (abnormal milk and abnormal udder) cases of clinical mastitis (CM) occurring in a single quarter of cows on Wisconsin farms (n=4) and to determine risk factors associated with those outcomes. Duplicate milk samples were collected from the affected quarter of each cow for microbiological analysis at the onset of CM (PRE) and 21 d later (POST). Cows were treated only in the affected quarter using an intramammary product containing 125 mg of ceftiofur. Bacteriological cure was defined as absence of pathogens in the POST sample obtained from the enrolled quarter. Recurrence was defined for the cow when CM occurred after the milk-withholding period for the enrolled case of CM. Retention in the herd was defined when a cow was retained within the herd for the 60-d follow-up period. Somatic cell count reduction (SCCR) was defined at the cow level as somatic cell count (SCC) below 200,000 cells/mL at the Dairy Herd Improvement Association test day occurring between 21 to 55 d post-treatment. The effects of farm, days in milk, parity, severity, microbiological diagnosis at PRE, previous milk yield, previous SCC, previous occurrence of CM and treatment duration on selected post-treatment outcomes were assessed using Chi-squared analysis and logistic regression. Microbiological results at PRE were distributed as: Escherichia coli (n=14), Klebsiella spp. (n=11), Enterobacter spp. (n=8), Serratia spp. (n=7), other gram-negative species (n=3), Streptococcus spp. (n=25), coagulase-negative staphylococci (n=4); Staphylococcus aureus (n=1); Streptococcus agalactiae (n=1), other gram-positive species (n=9), and culture negative (n=60). Treated quarters were more likely to experience bacteriological cure when the cow experienced CM for the first time in the lactation and when no pathogen was recovered from PRE milk samples obtained from the enrolled quarter.

Post-transcriptional regulation of vascular endothelial growth factor: Implications for tumor angiogenesis

Institute of Scientific and Technical Information of China (English)

Peter S Yoo; Abby L Mulkeen; Charles H Cha

2006-01-01

Vascular endothelial growth factor (VEGF) is a potent secreted mitogen critical for physiologic and tumor angiogenesis. Regulation of VEGF occurs at several levels, including transcription, mRNA stabilization,translation, and differential cellular localization of various isoforms. Recent advances in our understanding of posttranscriptional regulation of VEGF include identification of the stabilizing mRNA binding protein, HuR, and the discovery of internal ribosomal entry sites in the 5'UTR of the VEGF mRNA. Monoclonal anti-VEGF antibody was recently approved for use in humans, but suffers from the need for high systemic doses. RNA interference (RNAi)technology is being used in vitro and in animal models with promising results. Here, we review the literature on post-transcriptional regulation of VEGF and describe recent progress in targeting these mechanisms for therapeutic benefit.

Full Text Available This article discusses the factors present in post-merger integration of Systems and Information Technology (SIT that lead to positive and negative results in mergers and acquisitions (M & A. The research comprised three of the largest acquiring banks in Brazil. We adopted two methods of research, qualitative, to operationalize the theoretical concepts and quantitative, to test the hypotheses. We interviewed six executives of banks that held relevant experience in M & A processes. Subsequently, we applied questionnaires to IT professionals who were involved in the SIT integration processes. The results showed that the quality and expertise of the integration teams and managing the integration were the most relevant factors in the processes, with positive results for increased efficiency and the increased capacity of SIT. Negative results were due to failures in exploiting learning opportunities, the loss of employees and the inexpressive record of integration procedures.

Femoral neck fractures are frequent in the elderly population and lead to high morbidity and mortality. Hemiarthroplasty is an established surgical procedure for displaced intracapsular femoral neck fractures. Post-operative infection is frequent and is potentially devastating for the patient and the healthcare services. The goal of this study was to identify the risk factors of infection after hemiarthroplasty and help adapt our surgical practice. A systematic review of the literature was performed in July 2015 by two authors using the MedLine, PubMed and Cochrane databases. We used the MeSH keywords "hip hemiarthroplasty" AND "infection" to identify risk factors and methods of prevention for surgical site infection after hemiarthroplasty. Following the search, two authors independently performed the first stage based on titles and abstracts. Thirty-seven articles were selected. Review and analysis of the references was performed to find other articles of interest. Thirteen articles were selected to analyse. According to literature, the surgical site infection (SSI) rate after hip hemiarthroplasty (HHA) is between 1.7 and 7.3 %. Pre-operative comorbidities (obesity, liver disease, advanced age), operative conditions (junior surgeon, uncemented stems, time of surgery) and post-operative management (length of hospitalisation, haematoma, prolonged wound drainage and two urinary catheterisations) were identified as risk factors of surgical site infection. Authors describe conditions to decrease the incidence of these complications and underline the importance of "a specialised hip team" that provides fast care and helps decrease the duration of hospitalisation. Careful patient management for hemiarthroplasty is vital and may decrease the incidence of surgical site infection, which is associated with high morbidity and high procedure cost. Our review suggests that there are specific correctable risk factors for SSIs after HHA. Being able to identify these risk factors

Discrimination and distress among Afghan refugees in northern California: The moderating role of pre- and post-migration factors

Science.gov (United States)

2018-01-01

This study investigates the effect of perceived discrimination on the mental health of Afghan refugees, and secondly, tests the distress moderating effects of pre-migration traumatic experiences and post-resettlement adjustment factors. In a cross-sectional design, 259 Afghans completed surveys assessing perceived discrimination and a number of other factors using scales developed through inductive techniques. Multivariable analyses consisted of a series of hierarchical regressions testing the effect of perceived discrimination on distress, followed by a sequential analysis of moderator variables. Perceived discrimination was significantly associated with higher distress, and this relationship was stronger among those with a strong intra-ethnic identity and high pre-resettlement traumatic experiences. The expected buffering effects of civic engagement, ethnic orientation (e.g. integration), and social support were not significant. Discrimination is a significant source of stress for Afghan refugees, which may exacerbate stresses associated with other pre- and post-migration stressors. Future research is needed to tailor interventions that can help mitigate the stress associated with discrimination among this highly vulnerable group. PMID:29782531

Full Text Available There is a wide body of evidence showing a significant increase in the adoption of mergers and acquisitions (M&A worldwide. Moreover, research confirms that the integration and implementation stage (post-M&A has a major impact on the success or failure of a merger or acquisition. Therefore it has become increasingly important to explore the post-M&A phase further in order to support the management teams of organizations pursuing a merger or acquisition in meeting all their desired objectives. This paper proposes a framework to help in the successful execution of M&A. The framework contains three main elements: the motives, success factors and key success indicators (KSI. A qualitative research approach using the multiple case study methodology was conducted to test the framework. Ten case studies were selected from the industrial sector in Egypt and used to validate the research. The final version of the M&A framework was provided after applying the research results. Considering the practical implications of the M&A framework, a tool was proposed for its application in light of the balanced scorecard (BSC methodology. The proposed M&A scorecard tool should be used in the strategic planning and execution of M&A. Both the proposed M&A framework and the M&A scorecard tool should be used to guide the implementation of M&A in order to increase the success rate enjoyed by organizations.

Investigations of drinking behavior across military deployment cycles are scarce, and few prospective studies have examined risk factors for post-deployment alcohol misuse. Prevalence of alcohol misuse was estimated among 4645 US Army soldiers who participated in a longitudinal survey. Assessment occurred 1-2 months before soldiers deployed to Afghanistan in 2012 (T0), upon their return to the USA (T1), 3 months later (T2), and 9 months later (T3). Weights-adjusted logistic regression was used to evaluate associations of hypothesized risk factors with post-deployment incidence and persistence of heavy drinking (HD) (consuming 5 + alcoholic drinks at least 1-2×/week) and alcohol or substance use disorder (AUD/SUD). Prevalence of past-month HD at T0, T2, and T3 was 23.3% (s.e. = 0.7%), 26.1% (s.e. = 0.8%), and 22.3% (s.e. = 0.7%); corresponding estimates for any binge drinking (BD) were 52.5% (s.e. = 1.0%), 52.5% (s.e. = 1.0%), and 41.3% (s.e. = 0.9%). Greater personal life stress during deployment (e.g., relationship, family, or financial problems) - but not combat stress - was associated with new onset of HD at T2 [per standard score increase: adjusted odds ratio (AOR) = 1.20, 95% CI 1.06-1.35, p = 0.003]; incidence of AUD/SUD at T2 (AOR = 1.54, 95% CI 1.25-1.89, p risk of alcohol-related problems post-deployment.

Full Text Available Technical and environmental factors responsible of bird electrocution have been analyzed in low and medium tension power lines in a bird important area placed in the south of Alicante province (SE Spain. One hundred eighty six dead birds (119 birds of prey have been located in 182 poles inspected. Most species are legally protected and some are in jeopardy. Some pole types with suspended insulators have caused the same number of victims than poles with rigid insulators. Poles with rigid insulators in two levels produce more accidents than poles with one level. A different pole use according to the habitat has been observed. Birds of prey avoid poles in cultures, in the vicinity of roads and in flatlands or in hill tops. Furthermore, more electrocutions occur near bath zones. Poles in high places and located near to human altered habitats, where feeding is easy, are preferred by remainder birds.

Se analizan los factores técnicos y ambientales responsables de la electrocución de aves en tendidos de media y baja intensidad -situados en un área con una valiosa población de aves- en el sur de la provincia de Alicante. Se han localizado 186 aves muertas (119 rapaces en 182 postes visitados. La mayoría han sido especies protegidas, encontrándose, algunas de ellas, especialmente amenazadas. Los resultados muestran que algunos tipos de poste, con aisladores suspendidos, provocan un número de accidentes similar a otros tipos de postes con aisladores rígidos. Los postes con aisladores rígidos en dos planos producen más víctimas que los que presentan un único plano. Se observa que las aves realizan un uso diferente del poste en función del hábitat que lo rodea. Las rapaces evitan los postes situados sobre cultivos, los más próximos a las carreteras y los ubicados en zonas llanas o en las partes más altas de las laderas. Se encuentran más rapaces electrocutadas en aquellos postes próximos a zonas de baño. Para el resto de aves los

Immigrant Entrepreneurship in Post-Socialist Countries of the European Union: Motives and Patterns of Entrepreneurship of Post-Soviet Immigrants in Hungary

2017-01-01

Full Text Available This paper explores the relationship between migration, entrepreneurship, and foreign direct investments by focusing on entrepreneurial activities of post-Soviet (immigrants in Hungary in periods between 1991 and 2016. Post-Soviet migrants are in focus because between 1956 and 1989 the Soviet Union coercively kept Hungary in the Socialist bloc. Based on surveys and in-depth interviews, this paper reveals that there are considerable differences in patterns of entrepreneurship among post-Soviet immigrant entrepreneurs depending mostly on time of their arrival to Hungary. Similarly, motives for entrepreneurship among the first-wave migrants combine negative factors in the former Soviet Union with positive factors encountered in Hungary, while factors in Hungary recognized as positive by most post-Soviets prevail in motives for later waves of post-Soviet migration and entrepreneurship in Hungary. The paper also demonstrates that many relatively small investments have been conducted since 2000 by citizens of post-Soviet countries to Hungary. Some of them are transforming into an entrepreneurial activity, serving also as a basis for immigration to Hungary.

Resilience: Protective Factors for Depression and Post Traumatic Stress Disorder among African American Women?

Full Text Available There is a great need to carefully examine issues that may elevate one’s risk for mental illness and develop strategies to mitigate risk and cultivate resilience.  African Americans, specifically African American women (AAW, are disproportionately affected by mental illness, including depression and post-traumatic stress disorder (PTSD.  Higher rates of PTSD among AAW may be explained by significant rates of trauma exposure.  Higher resiliency in individuals with mental illnesses is associated with better treatment response/outcomes.  An examination of two (2 promising psycho-educational curricula for AAW at risk for depression and PTSD supports consideration of resilience as a protective factor among this population.  Strengthening psychological resilience among diverse AAW at risk for depression and/or PTSD may serve as a protective factor for symptom severity.  Multidimensional prevention and intervention strategies should incorporate culturally-centered, gender-specific, and strengths-based (resilience models of care to help encourage mental health help-seeking and promotion of wellness for AAW.

The aim of this study was to identify the potential risk factors for the development of post-traumatic stress disorder in mothers and fathers following infant hospitalisation in the neonatal intensive care unit. The development of neonatal intensive care units has increased the survival rate of infants. However, one of the major parental problems is post-traumatic stress disorder. An observational study covered 125 parents (72 mothers and 53 fathers) of infants aged 3-12 months who were hospitalised in the neonatal intensive care unit during the neonatal period. Third-referral neonatal intensive care unit. Several standardised and self-reported research tools were used to estimate the level of post-traumatic stress symptoms (Impact Event Scale-Revised), perceived stress (Perceived Stress Scale) and coping strategies (COPE Inventory). The respondents also completed a Parent and Infant Characteristic Questionnaire. The mothers and fathers did not differ in their parental and infant characteristics. Post-traumatic stress disorder was present in 60% of the mothers and 47% of the fathers. Compared to the fathers, the mothers felt greater stress (p = .020) and presented a higher severity of post-traumatic stress disorder (p stress disorder in the mothers. In the fathers, an Apgar test at 1 min after birth (p = .030) and a partner's post-traumatic stress disorder (p = .038) were related to post-traumatic stress disorder. The mothers compared to the fathers were more likely to use strategies such as: positive reinterpretation and growth, focusing on and venting of emotions, instrumental social support, religious coping and acceptance. In the fathers, the predictors included an Apgar score at 1 min after birth, a lack of congenital anomalies in the child and mental disengagement. Risk factors for post-traumatic stress disorder, as well as coping strategies, differ in women compare to men. Knowledge of risk factors for post-traumatic stress disorder, specific to

Esta porosidad de categorías y de criterios de agrupamiento es el nexo entre los textos de diferentes culturas literarias –desde la oralidad a la relectura literaria y posmoderna de las mitografías antiguas– y es lo que nos ha permitido trazar algunos paralelismos entre las narrativas míticas y las de la posmodernidad. This article deals with the integrated texts of cyclic tales and also the instruments and tools to catalog the components of fiction in a broad sense, the way to define the units of analysis (narratologies and the poetics of each period, with the emphasis on readers’ responses to determine the modes of narrative texts.

Full Text Available La gerencia universitaria de hoy, requiere asumir un proceso de transformación organizacional, que le permita describir un equilibrio entre su identidad institucional y los cambios sustanciales exigidos desde todos sus ámbitos, a fin de mejorar los procesos académicos, cohesionar con éxito las funciones básicas y por ende lograr la calidad académica deseada. Surge como inquietud el presente artículo el cual pretende indagar sobre algunos esfuerzos que la Universidad del Zulia ha adelantado en este sentido, pero sobre todo hacer énfasis en la perspectiva de algunos actores del proceso, representados por el personal docente y de investigación, que para el período 2000-2001 se desempeño como personal directivo Para la recolección de los datos se asumió en primer término la técnica cualitativa del grupo focal, permitiendo así lograr suficiente información para aplicar luego, una muestra probabilística que arrojó un tamaño de 39 unidades con un nivel de confianza del 95%. Se concluye que los gerentes universitarios están conscientes de los problemas de carácter operativo que obstaculizan el proceso de cohesión exitosa de las funciones básicas. Sin embargo, no evidencian conocimiento exhaustivo sobre el desarrollo de procesos gerenciales, para el logro de los cursos de acción enunciados por esos mismos actores. Se recomienda sobre la necesidad de formar una gerencia universitaria sólida, en el compromiso de la labor constante en materia de información y conocimiento, de tal forma que los cambios implantados sean percibidos de manera objetiva, internalizados y compartidos por la comunidad universitaria, en la búsqueda de que ellos se conviertan en piezas del proceso de cambio institucional.

A new hypothesis for the importance of seed dispersal in time

procesos fisiológicos que disparan su germinación. Sin embargo, la dispersión de semillas por animales de bajas tasas metabólicas y largos tiempos de retención, como por ejemplo los reptiles, podría ser considerada otro tipo de dispersión en el tiempo. Este estudio prueba la hipótesis que las semillas dispersadas por tortugas pueden evadir a los depredadores en el tiempo. Semillas depositadas bajo árboles parentales luego de que la cosecha haya terminado es ventajoso para escapar de depredadores denso-dependientes y por lo tanto deberían mostrar mayores tasas de supervivencia. La hipótesis se probó en cuatro especies de plantas amazónicas, Dicranostyles ampla, Oenocarpus bataua, Guatteria atabapensis y Ocotea floribuna, durante dos periodos: durante la cosecha y varios días después de la cosecha de frutos. Los experimentos se llevaron en dos estaciones biológicas de la Amazonia colombiana (Caparú y Zafire. Los principales depredadores de semillas fueron los no vertebrados y por lo tanto fueron el factor que más influyó en la supervivencia de las semillas en ambas áreas de estudio. De las cuatro especies probadas, sólo Guatteria atabapensis validó la hipótesis de la ventaja de la dispersión en el tiempo. Para esta especie, la depredación de semillas por vertebrados después del periodo de cosecha incrementó (de 4.1% a 9.2% mientras que la depredación de semillas por no vertebrados disminuyó (de 54.0% a 40.2%. Por el contrario, la depredación de semillas por vertebrados y por no vertebrados después del período de la cosecha para D. ampla incrementó (de 7.9% a 22.8% y de 40.4% a 50.6% respectivamente, sugiriendo saciación de depredadores. Los resultados sugieren que para algunas especies, el escape en el tiempo podría ser ventajoso para evadir algunos tipos de depredadores. El escape en el tiempo podría ser una dimensión adicional en donde las semillas podrían alcanzar lugares adecuados para su reclutamiento. Futuros estudios deber

Beyond Trauma: Post-resettlement Factors and Mental Health Outcomes Among Latino and Asian Refugees in the United States.

2016-08-01

War-related traumas impact refugees' mental health. Recent literature suggests that structural and sociocultural factors related to the resettlement also become critical in shaping refugees' mental health. So far, there is limited empirical evidence to support this claim among resettled refugees. Resettlement contextual factors that influence mental health outcomes were examined using Latino and Asian refugees (n = 656) from a nationally representative survey. Linear and logistic regressions predicted factors associated with the study's outcomes (self-reported mental health, mood disorders, and anxiety disorders). Post-resettlement traumas were significantly associated with mental health outcomes, but pre-resettlement traumas were not. Unemployment, everyday discrimination, and limited English were significantly associated with mental health outcomes among both Latino and Asian refugees. The outcomes indicate that resettlement contextual factors have a significant association with refugees' mental health. Therefore, future studies with refugees must pay closer attention to structural and sociocultural factors after resettlement.

The aim of this study was to investigate the post-partum recovery of blood pressure (BP) in women with hypertensive disorders of pregnancy (HDP) and to evaluate HDP risk factors. A total of 124 patients with gestational hypertension (n = 63) or pre-eclampsia (n = 61) who gave birth at Peking University People's Hospital between January and December 2013 were included in this study. The recorded clinical and laboratory parameters included the patients' general information, maternal pre-pregnancy body mass index, gestational weight gain, gestational age at onset and delivery, delivery mode and time taken for BP to return to normal level. Logistic regression analysis was performed to evaluate the influence of various risk factors on post-partum BP recovery. The mean interval for BP normalization was 24.1 ± 22.8 days (median, 7 days). Forty-six percent of the patients recovered from hypertension within three days, and 75% recovered within six weeks of delivery. About 90% of the patients required 60 days for BP to normalize after delivery. After adjusting for confounding factors, post-partum recovery from hypertension was found to be influenced by hypertension severity, maternal serum albumin level, a family history of hypertension and gestational week at delivery. The BP of the majority of the patients with gestational hypertension or pre-eclampsia returned to normal within 60 days of delivery. Hypertension severity, maternal serum albumin level, a family history of family hypertension and gestational week at delivery influenced the time required for BP normalization. © 2016 Japan Society of Obstetrics and Gynecology.

Post-translational processing and secretion of atrial natriuretic factor

International Nuclear Information System (INIS)

Shields, P.P.

1988-01-01

The post-translational processing and regulated secretion of atrial natriuretic factor (ANF) were studied in primary cultures of rat cardiac myocytes. Cultures were established from neonatal rat atria or ventricles, and were maintained for 7-14 days in complete serum free medium. The cultures contained high and constant levels of ANF-(1-126), the known storage form of the hormone in vivo. The cultures also secreted ANF-(1-126), instead of the known circulating form of the hormone, ANF-(99-126). However, the inclusion of the glucocorticoids dexamethasone or hydrocortisone in the culture medium increased the levels of ir-ANF contained and secreted by the cultures, and caused both atrial and ventricular cultures to secrete principally ANF-(99-126) instead of ANF-(1-126). The secreted peptide was shown to be authentic ANF-(99-126) by chromatographic, amino acid composition and radiosequence analysis, thus confirming that the cultures were accurately processing ANF to the in vivo circulating form in the presence of glucocorticoids. Glucocorticoids also caused an increase in size and clustering of atrial myocytes as determined by immunocytochemical analysis, but the morphological effects could be dissociated from the stimulation of ANF-(99-126) secretion by manipulating the timing of glucocorticoid exposure. The location of ANF-(99-126) formation was investigated using biosynthetically labeled 35 S-Cys-ANF-(1-126) in conjunction with actively processing cultures

To investigate the relationships between sociodemographic, pre- and post-migration variables with prevalence of psychological distress and global functioning in a heterogeneous sample of torture survivors. Clients referred from resettlement agencies via the Office of Refugee Resettlement (ORR) to a community clinic in the United States (N = 278) were interviewed with structured, translated questionnaires. Univariate and multivariate logistic regression analyses determined the associations of sociodemographic, pre-, and post-migration risk factors with posttraumatic stress disorder (PTSD), depression, anxiety, and global functioning. Regression data indicate that length of time between arrival in US and clinical services was significantly associated with PTSD and depression; participants receiving services after 1 year of resettlement were more likely to experience PTSD (adjusted OR = 3.29) and depression (adjusted OR = 4.50) than participants receiving services within 1 year. Anxiety was predicted by female gender (adjusted OR = 3.43), age over 40 years (adjusted OR = 3.12), Muslim religion (adjusted OR = 2.64), and receiving medical services (AOR 3.1). Severely impaired global functioning was associated with female gender (adjusted OR = 2.75) and unstable housing status (adjusted OR = 2.21). Findings highlight the importance of examining post-migration variables such as length of time in country prior to receiving services in addition to pre-migration torture history upon relocated torture survivors. Clinicians and policy-makers should be aware of the importance of early mental health screening and intervention on reducing the psychiatric burden associated with torture and forced relocation.

Specifically, we sought to find out what political variables influence this behaviour and what uses of the Internet seem to favour it. We also studied the effect of a number of socio-demographic control variables. To do this, we used the data from the 2007 survey on “The Internet and political participation” (ref. 2736, run by the Centro de Investigaciones Sociológicas. We began with an exploratory factor analysis, which was followed by a logistic regression. In order to exclude influences on the model due to the first-level of digital divide, the sample chosen for the analysis comprised Spanish Internet Users.

Perspective on physiological/endocrine and nutritional factors influencing fertility in post-partum dairy cows.

2010-09-01

Increasing reproductive performance of post-partum lactating dairy cows is a multi-factorial challenge involving disciplines of production medicine, nutrition, physiology and herd management. Systems of programmed timed insemination have been fine-tuned to achieve pregnancy per artificial inseminations (AI) approximating 45%. Systems have optimized follicle development, integrated follicle development with timing of induced corpus luteum regression and fine-tuned sequential timing of induced ovulation and AI. Use of programmes for insemination have identified occurrence of anovulatory ovarian status, body condition, uterine health and seasonal summer stress as factors contributing to reduced herd fertility. Furthermore, programmes of timed insemination provide a platform to evaluate efficacy of nutritional and herd health systems targeted to the transition and post-partum periods. The homeorhetic periparturient period, as cows deal with decreases in dry matter intake, results in a negative energy balance and is associated with a period of immunosuppression. Cows that transition well will cycle earlier and have a greater risk of becoming pregnant earlier post-partum. The innate arms of the immune system (acute and adaptive) are suppressed during the periparturient period. Cows experiencing the sequential complex of disorders such as dystocia, puerperal metritis, metritis, endometritis and subclinical endometritis are subsequently less fertile. Targeted strategies of providing specific nutraceuticals that provide pro- and anti-inflammatory effects, such as polyunsaturated fatty acids (e.g., linoleic, eicosapentaenoic/docosahexaenoic, conjugated linoleic acid), sequential glycogenic and lipogenic enrichment of diets, and organic selenium appear to differentially regulate and improve the immune and reproductive systems to benefit an earlier restoration of ovarian activity and increased fertility. © 2010 Blackwell Verlag GmbH.

It is unclear which potentially modifiable risk factors best predict post-trauma psychiatric disorders. We aimed to identify pre-trauma risk factors for post-traumatic stress disorder (PTSD) or major depression (MD) that could be targeted with resilience interventions. Newly recruited paramedics (n = 453) were assessed for history of mental disorders with structured clinical interviews within the first week of their paramedic training and completed self-report measures to assess hypothesized predictors. Participants were assessed every 4 months for 2 years to identify any episodes of PTSD and MD; 386 paramedics (85.2%) participated in the follow-up interviews. In all, 32 participants (8.3%) developed an episode of PTSD and 41 (10.6%) an episode of MD during follow-up. In all but nine cases (2.3%), episodes had remitted by the next assessment 4 months later. At 2 years, those with episodes of PTSD or MD during follow-up reported more days off work, poorer sleep, poorer quality of life, greater burn-out; and greater weight-gain for those with PTSD. In line with theories of PTSD and depression, analyses controlling for psychiatric and trauma history identified several pre-trauma predictors (cognitive styles, coping styles and psychological traits). Logistic regressions showed that rumination about memories of stressful events at the start of training uniquely predicted an episode of PTSD. Perceived resilience uniquely predicted an episode of MD. Participants at risk of developing episodes of PTSD or depression could be identified within the first week of paramedic training. Cognitive predictors of episodes of PTSD and MD are promising targets for resilience interventions.

The aim of this paper was to examine the role of perinatal, obstetric and post partum factors on maternal and paternal stress. It will present the first examination of the role of prenatal, obstetric, post-partum, and demographic variables in parenting stress for mothers and fathers at 9 months. Data from 6821 parental dyads of 9-month-old infants were extracted from the Growing Up in Ireland National Longitudinal Study of Children. Participants completed the Parental Stress Scale, the Dyadic Adjustment Scale, the Quality of Attachment Sub-scale from the Maternal and Paternal Postnatal Attachment Scales, and a single item health status question from the Short Form 12 Health Survey. Information on prenatal care, pregnancy complications, obstetric outcomes, infant health, and participant demographics were also collected. Separate hierarchical linear regressions were conducted for mothers and fathers Results: Mothers reported higher levels of parenting stress than fathers (p stress was predicted by attachment, own health status, average sleep, occupation, household income, and having a very rapid labor. Paternal parenting stress was predicted by attachment and own health status. A range of perinatal factors was associated with an increased risk of higher parenting stress at 9 months post-partum and the roles of these factors differ between mothers and fathers. These findings are important for predicting and reducing risk of parenting stress in both genders.

Understanding how veterans appraise their post-deployment experiences could provide insight into better assisting their deployment transitions. We aimed to assess the factor structure of positive and negative post-deployment appraisals in Australian veterans and to examine the resultant factors in their relationship with military stress and psychological health. Questions capturing post-deployment attitudes were developed by the researchers in collaboration with veterans. The questions were administered to 1938 veterans and the results factor analysed. The relationships between post-deployment appraisal, military stress and psychological health were examined using Structural Equation Modelling. A three-factor solution was found for the post-deployment appraisal questions; representing personal development, lack of recognition, and appreciation of life and country. Military stress was associated with the three factors and psychological health. The three factors were weakly to moderately associated with psychological health. Mediation between military stress and psychological health by any post-deployment appraisal factor was minimal. Post-deployment appraisal measures three important attitudes and concerns of veterans after deployment. Military stress is associated with the post-deployment appraisal factors. However, the factors did not mediate the relationship between military stress and psychological health. These factors provide insight into how veterans appraise their complex array of post-deployment experiences, and may provide useful in regard to transitions and integration into civilian life.

Modified ultrafiltration (MUF) is a technique that hemoconcentrates residual CPB circuit blood and the patient at the same time. Hemoconcentration and MUF are Class 1-A recommendations in the anesthesia and surgical blood conservation guidelines. This study evaluated the off-line MUF process of the Hemobag (HB, Global Blood Resources, Somers, CT, USA) to quantitate coagulation factor levels, platelet (PLT) count and function in one facility and cellular growth factor concentrations of the final product that were transfused to the patient in another facility In two cardiac surgery facilities, after decannulation, the extracorporeal circuit (ECC) blood from 22 patients undergoing cardiac surgery was processed with the HB device. In eleven patients from the first facility by the study design, blood samples for coagulation factor levels and PLT aggregation were drawn from the reservoir of the MUF device pre- and post-processing. The samples (n = 11) were sent to a reference laboratory where testing for prothrombin time (PT), international normalized ratio (INR), activated partial thromboplastin time (aPTT), reptilase time, fibrinogen, clotting factors II, V, VII, VIII, IX, X, ADAMTS-13, protein C, protein S, antithrombin III, von Willebrand Factor (vWF), and platelet (PLT) aggregation were performed. A portion of the final concentrated HB blood samples (n = 5-10) from the second facility by design were evaluated for transforming and platelet-derived cellular growth factor concentrations. On average, approximately 800 - 2000 mls of whole blood were removed from the ECC post-CPB for processing in the HB device. After processing, there was, on the average, approximately 300 - 950 mls of concentrated whole blood salvaged for reinfusion. The PT and INR were significantly lower in the post-processing product compared to the pre-processing samples while the aPTT times were not significantly different. All coagulation factors and natural anti-coagulants were significantly

A cross-sectional study was carried out to identify species and determine the prevalence of Cryptosporidium sp. shedding in pre-weaned and post-weaned dairy calves and to identify management factors that may be contributing to disease. A total of 240 calf faecal samples were collected from 16 farms in two districts in Johor, Malaysia, and screened by PCR. The overall Cryptosporidium prevalence was 27.1%. The prevalence of Cryptosporidium species in pre-weaned calves was 32.4% for C. parvum, 26.5% for C. bovis, followed by C. andersoni (20.6%), C. ryanae (11.8%) and mixed sp. (8.8%). The prevalence of Cryptosporidium species in post-weaned calves was 35% for C. bovis followed by C. andersoni and C. ryanae (30% each) and mixed sp. (5%). Subtyping analysis of 8 of the 11 C. parvum isolates at the gp60 locus identified five isolates as IIdA15G1, one as IIa18A3R1 and two isolates as IIa17G2R1. Management factors that increased the risk of Cryptosporidium infection included having other cattle farms close by, feeding calves with saleable milk, keeping pre-weaned calves in pens with slatted floors and keeping post-weaned calves in pens with a sand floor.

The process of becoming a humanitarian migrant is potentially damaging to mental health. We examined the association between pre-migration and post-migration potentially traumatic events and stressors and mental health, and assessed the moderating effect of post-migration stressors in humanitarian migrants in Australia. In this study, we used the first wave of data between 2013 and 2014 from the Building a New Life in Australia survey. The survey included 2399 migrants who had arrived in Australia holding a permanent humanitarian visa 3-6 months preceding the survey, with 77% and 23% of participants being granted visas through offshore and onshore humanitarian programmes, respectively. Post-traumatic stress disorder (PTSD) was measured with the Post-traumatic Stress Disorder 8 items (PTSD-8) and severe mental illness was measured with the Kessler Screening Scale for Psychological Distress (K6). Pre-migration potentially traumatic events and post-migration stressors related to asylum process and resettlement were measured with a self-reported questionnaire. Of the 2399 participants, 762 (31%; 95% CI 29·4-33·2) had PTSD and 394 (16%; 95% CI 14·2-17·2) had severe mental illness. The mean number of pre-migration potentially traumatic events was 2·1 (SD 1·4). 64%, 59%, 49%, and 18% of participants reported poor social integration, economic problems, worrying about family or friends overseas, and loneliness as post-migration stressors. Pre-migration potentially traumatic events and post-migration stressors were positively associated with PTSD and severe mental illness. Factors significantly modifying the association between pre-migration potentially traumatic events and mental health after controlling for confounding factors were resettlement related stressors, including loneliness (odds ratio 1·17, 95% CI 1·05-1·28 for PTSD and 1·28, 1·16-1·41 for severe mental illness) and the number of social integration stressors (1·10, 1·05-1·16 for PTSD).

2008-11-01

Full Text Available Abstract Background About twice as many women as men develop post-traumatic stress disorder (PTSD, even though men as a group are exposed to more traumatic events. Exposure to different trauma types does not sufficiently explain why women are more vulnerable. Methods The present work examines the effect of age, previous trauma, negative affectivity (NA, anxiety, depression, persistent dissociation, and social support on PTSD separately in men and women. Subjects were exposed to either a series of explosions in a firework factory near a residential area or to a high school stabbing incident. Results Some gender differences were found in the predictive power of well known risk factors for PTSD. Anxiety predicted PTSD in men, but not in women, whereas the opposite was found for depression. Dissociation was a better predictor for PTSD in women than in men in the explosion sample but not in the stabbing sample. Initially, NA predicted PTSD better in women than men in the explosion sample, but when compared only to other significant risk factors, it significantly predicted PTSD for both men and women in both studies. Previous traumatic events and age did not significantly predict PTSD in either gender. Conclusion Gender differences in the predictive value of social support on PTSD appear to be very complex, and no clear conclusions can be made based on the two studies included in this article.

Objective: To evaluate the frequency and associated factors in the post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis. Study Design: Cross-sectional analytical study. Place and Duration of Study: Endoscopy Suite of Surgical Unit IV, Civil Hospital, Karachi, from December 2009 to November 2010. Methodology: Patients undergoing ERCP were included. Patients who had presented with pancreatitis or raised amylase levels before procedure or patients who had previous history of surgery on the biliary or pancreatic systems were excluded from the study. Pearson chi-square and Fisher's exact test were used for qualitative data and t-test for quantitative data. Significance was taken as p=0.05. Odds ratio was calculated for the qualitative data using 95% confidence interval. Results: Age of the study population ranged from 9 to 90 years (mean age 46.5 A+- 14.94 years, median 45 years). Male to female ratio was 1:1.87. Pancreatitis was seen in 18 patients (3.6%), mild in 15 (3%), moderate in one (0.2%) and severe in 2 (0.4%). Mean amylase level at 4 hours and 24 hours was 280.93 A+- 539.13 and 168.83 A+- 338.34 respectively. Pancreatitis was seen in 15/326 (4.6%) females and 3/174 (1.72%) males. Statistically significant increased risk for pancreatitis was seen in difficult cannulation (9.8%, p = 0.006), prolonged cannulation time (7.6 minute, p = 0.002), pancreatic duct cannulation (13.7%, p = 0.001) and pancreatic duct contrast injection (13.4%, p < 0.001). Conclusion: The frequency of post-ERCP pancreatitis was 3.6%. Difficult cannulation, pancreatic duct cannulation, pancreatic duct contrast injection and balloon sphincteroplasty were associated with higher frequency of post-ERCP pancreatitis. Reuse of ERCP accessories poses no additional risk to the frequency of pancreatitis. (author)

Suicide is a major public health concern worldwide, and mental disorders have been identified as a main risk factor. Suicide is also one of the leading causes of perinatal maternal mortality, but very few studies have focused on suicide attempts (SA) in the perinatal period. This work aims to assess risk factors associated with SA in pregnancy and in the post-partum period in women with mental health disorders. Women (n = 1439) with psychiatric disorders jointly admitted with their infant to 16 psychiatric Mother-Baby Units over 10 years (2001-2010) were assessed retrospectively for the occurrence of SA in pregnancy or the postpartum period. Multinomial logistic regression was used to explore the independent impact of maternal sociodemographic characteristics, history of childhood maltreatment and abuse, current mental illness and pregnancy data on SA in pregnancy and/or postpartum. One hundred and fifty-four women (11.68%) attempted suicide: 49 in pregnancy (3.71%) and 105 (7.97%) in the post-partum period. SA in pregnancy was related to alcohol use (OR = 2.37[1.02-5.53]; p = 0.04) and smoking during pregnancy (OR = 1.87[1.01-3.49]; p = 0.04) and also to a history of miscarriage (OR = 2.29[1.18-4.41]; p = 0.01). SA in the post-partum period was associated with major depressive episode (OR = 2.72[1.40-5.26]; p = 0.003) or recurrent depression (OR = 4.12[2.25-7.51], p depression in the perinatal period.

Pancreatitis is the most common complication of endoscopic retrograde cholangiopancreatography (ERCP). Several patients´ or procedure related risk factors for post-ERCP pancreatitis (PEP) have been suggested. The aim of this study was to validate the risk factors for PEP in a high-volume center. All patients undergoing first time ERCP at a tertiary referral center between December 2010 and October 2013 were retrospectively included. PEP was defined according to the Atlanta Classification. 344 patients were included in the final analysis. The risk to develop PEP was increased in patients with chronic pancreatitis (odds ratio 3.7) and after inadvertent cannulation of the pancreatic duct (odds ratio 2.2), which occurred in 26.5% of the patients. Inadvertent cannulation occurred significantly more frequently in patients with difficult cannulation of the papilla duodeni major (odds ratio 12.7; passociated with an increased risk for difficult cannulation (odds ratio 3.0). Inadvertent cannulation of the pancreatic duct is a procedure related risk factor for PEP. Measurements on preventing inadvertent cannulation of the pancreatic duct should be established and studies on prophylactic measurements should focus particularly on patients with inadvertent cannulation of the pancreatic duct.

Post-stroke cognitive impairment: epidemiology, mechanisms and management

Sun, Jia-Hao

2014-01-01

Post-stroke cognitive impairment occurs frequently in the patients with stroke. The prevalence of post-stroke cognitive impairment ranges from 20% to 80%, which varies for the difference between the countries, the races, and the diagnostic criteria. The risk of post-stroke cognitive impairment is related to both the demographic factors like age, education and occupation and vascular factors. The underlying mechanisms of post-stroke cognitive impairment are not known in detail. However, the neuroanatomical lesions caused by the stroke on strategic areas such as the hippocampus and the white matter lesions (WMLs), the cerebral microbleeds (CMBs) due to the small cerebrovascular diseases and the mixed AD with stroke, alone or in combination, contribute to the pathogenesis of post-stroke cognitive impairment. The treatment of post-stroke cognitive impairment may benefit not only from the anti-dementia drugs, but also the manage measures on cerebrovascular diseases. In this review, we will describe the epidemiological features and the mechanisms of post-stroke cognitive impairment, and discuss the promising management strategies for these patients.

Surgical site infection (SSI) complicates approximately 2% of surgeries in the Veterans Affairs (VA) hospitals. Surgical site infections are responsible for increased morbidity, length of hospital stay, cost, and mortality. Surgical site infection can be minimized by modifying risk factors. In this study, we identified risk factors and developed accurate predictive surgical specialty-specific SSI risk prediction models for the Veterans Health Administration (VHA) surgery population. In a retrospective observation study, surgical patients who underwent surgery from October 2013 to September 2016 from 136 VA hospitals were included. The Veteran Affairs Surgical Quality Improvement Program (VASQIP) database was used for the pre-operative demographic and clinical characteristics, intra-operative characteristics, and 30-day post-operative outcomes. The study population represents 11 surgical specialties: neurosurgery, urology, podiatry, otolaryngology, general, orthopedic, plastic, thoracic, vascular, cardiac coronary artery bypass graft (CABG), and cardiac valve/other surgery. Multivariable logistic regression models were developed for the 30-day post-operative SSIs. Among 354,528 surgical procedures, 6,538 (1.8%) had SSIs within 30 days. Surgical site infection rates varied among surgical specialty (0.7%-3.0%). Surgical site infection rates were higher in emergency procedures, procedures with long operative duration, greater complexity, and higher relative value units. Other factors associated with increased SSI risk were high level of American Society of Anesthesiologists (ASA) classification (level 4 and 5), dyspnea, open wound/infection, wound classification, ascites, bleeding disorder, chemotherapy, smoking, history of severe chronic obstructive pulmonary disease (COPD), radiotherapy, steroid use for chronic conditions, and weight loss. Each surgical specialty had a distinct combination of risk factors. Accurate SSI risk-predictive surgery specialty

Rationale: The incidence and risk factors of post-traumatic stress disorder (PTSD) related to the intensive care unit (ICU) experience have not been reported in a mixed veteran and civilian cohort. Objectives: To describe the incidence and risk factors for ICU-related PTSD in veterans and civilians. Methods: This is a prospective, observational, multicenter cohort enrolling adult survivors of critical illness after respiratory failure and/or shock from three Veterans Affairs and one civilian hospital. After classifying those with/without preexisting PTSD (i.e., PTSD before hospitalization), we then assessed all subjects for ICU-related PTSD at 3 and 12 months post hospitalization. Measurements and Main Results: Of 255 survivors, 181 and 160 subjects were assessed for ICU-related PTSD at 3- and 12-month follow-up, respectively. A high probability of ICU-related PTSD was found in up to 10% of patients at either follow-up time point, whether assessed by PTSD Checklist Event-Specific Version (score ≥ 50) or item mapping using the Diagnostic and Statistical Manual of Mental Disorders-IV (DSM-IV). In the multivariable regression, preexisting PTSD was independently associated with ICU-related PTSD at both 3 and 12 months (P < 0.001), as was preexisting depression (P < 0.03), but veteran status was not a consistent independent risk factor for ICU-related PTSD (3-month P = 0.01, 12-month P = 0.48). Conclusions: This study found around 1 in 10 ICU survivors experienced ICU-related PTSD (i.e., PTSD anchored to their critical illness) in the year after hospitalization. Preexisting PTSD and depression were strongly associated with ICU-related PTSD. PMID:26735627

Bloch, Frédéric

2017-02-01

To test the hypothesis that post-traumatic stress disorder (PTSD) can appear after a fall and try to identify predictive factors for its development in older fallers. Systematic literature review and meta-analyses of studies on PTSD post fall in older subjects. One hundred seventy-seven indexed articles were identified, of which three had complete data on PTSD post fall in older subjects. Only the odds ratio of the association between history of fall and occurrence of PTSD was significant (odds ratio = 2.79 (95% CI, 1.03-7.53). The trend in our results, even though limited, reveals two groups of subjects: frail subjects that are at risk of developing PTSD and subjects who seem to be resistant to its development. A clear description of these two groups may help us identify the population at risk for delayed PTSD who could then benefit from dedicated treatment. Copyright © 2016 John Wiley & Sons, Ltd.

Delayed hemorrhage is an infrequent, but serious complication of colonoscopic polypectomy. Large size is the only polyp-related factor that has been unequivocally proven to increase the risk of delayed bleeding. It has been suggested that location in the right hemi-colon is also a risk factor. The objective of this study was to determine whether polyp location is an independent risk factor for delayed post-polypectomy hemorrhage. A retrospective case-control study was conducted in two university hospitals and two community hospitals. Thirty-nine cases and 117 controls were identified. In multivariate analysis, size and location were found to be independent polyp-related risk factors for delayed type hemorrhage. The risk increased by 13% for every 1 mm increase in polyp diameter (odds ratio (OR) 1.13, 95% confidence interval (CI) 1.05-1.20, Plocated in the right hemi-colon had an OR of 4.67 (1.88-11.61, P=0.001) for delayed hemorrhage. Polyps in the cecum seemed to be especially at high risk in univariate analysis (OR 13.82, 95% CI 2.66-71.73), but this could not be assessed in multivariate analysis as the number of cases was too small. Polyp type (sessile or pedunculated) was not a risk factor. Polyp location in the right hemi-colon seems to be an independent and substantial risk factor for delayed post-polypectomy hemorrhage. A low threshold for preventive hemostatic measures is advised when removing polyps from this region.

Post-Session Authentication

Entity authentication provides confidence in the claimed identity of a peer entity, but the manner in which this goal is achieved results in different types of authentication. An important factor in this regard is the order between authentication and the execution of the associated session....... In this paper, we consider the case of post-session authentication, where parties authenticate each other at the end of their interactive session. This use of authentication is different from session-less authentication (e.g., in RFID) and pre-session authentication (e.g., for access control.) Post......-session authentication, although a new term, is not a new concept; it is the basis of at least a few practical schemes. We, for the first time, systematically study it and present the underlying authentication model. Further, we show that an important class of problems is solvable using post-session authentication...

Although the role of anxiety disorders on the development of Post-partum Depression (PPD) have already been studied in literature, that of individual anxiety disorders has not received specific attention. The aim of this study is to investigate the role of Panic Disorder (PD) and family history for PD as risk factors for PPD. Six hundred women were recruited in a prospective, observational study at the 3rd month of pregnancy and followed up until the 6th month after delivery. At baseline, risk factors for PPD, Axis-I disorders and family history for psychiatric disorders were assessed. We investigated minor and major depression (mMD) occurred at 1st, 3rd and 6th months post-partum. Logistic regression models were used to estimate the association between PD, family history for PD and PPD. Forty women had mMD in the post-partum. PD during pregnancy (RR=4.25; 95%CI:1.48-12.19), a history of PD (RR 2.47; 95%CI:1.11-5.49) and family history for PD (RR=2.1; 95%CI:1.06-4.4) predicted PPD after adjusting for lifetime depression and risk factors for PPD. The response rate is moderately low, but it is similar to other studies. The drop out rate is slightly high, however the 600 women who completed the 6th month follow-up did not differ from the presence of PD at baseline. PD is an independent risk factor for PPD, underscoring need to assess PD symptoms during pregnancy. Furthermore, PD represents an important risk factor for the development of PPD and should be routinely screened in order to develop specific preventive interventions. Copyright 2009 Elsevier B.V.

This study aims to address and assess possible factors associated with nausea and vomiting (NV) following oral and maxillofacial surgery. A prospective study was carried out in the period from December 2013 to January 2016 targeting all attended cases in that period. For statistical analysis, Pearson chi-square and Fisher tests were used to verify association and ANOVA and Student's t tests to test for significant difference, p was defined as ≤0.05. The sample group consisted of 207 patients with an average age of 33.56 years (±13.23), and 70.5% of subjects were male. Calculations based on the predictive model showed that a female patient with prior history of nausea and vomiting who used opioids and had intra-oral surgical access would have a 96% chance of experiencing a nausea and vomiting episode. Other factors like age, being overweight, anesthesia, surgery duration, and duration of hospital stay also contribute so that these aspects must be paid careful attention prior to surgery to ensure a suitably orientated treatment that will avoid disturbances caused by post-operative nausea and vomiting. The occurrence of post-operative nausea and vomiting after oral and maxillofacial surgery was found to be more higher incidence associated to female patients who used opioids, who had a prior history of NV, whose surgery involved intra-oral access, who were in the second or third decades of their lives, who have above average weight, and who have long anesthesia when undergoing surgery, resulting in a long hospital stays.

Introduction Factors predictive of the need for red blood cell (RBC) transfusion in the intensive care unit (ICU) have been identified, but risk factors for transfusion after ICU discharge are unknown. This study aims identifies risk factors for RBC transfusion after discharge from the ICU. Methods A prospective, monocentric observational study was conducted over a 6-month period in a 24-bed medical ICU in a French university hospital. Between June and December 2003, 550 critically ill patients were consecutively enrolled in the study. Results A total of 428 patients survived after treatment in the ICU; 47 (11% of the survivors, 8.5% of the whole population) required RBC transfusion within 7 days after ICU discharge. Admission for sepsis (odds ratio [OR] 341.60, 95% confidence interval [CI] 20.35–5734.51), presence of an underlying malignancy (OR 32.6, 95%CI 3.8–280.1), female sex (OR 5.4, 95% CI 1.2–24.9), Logistic Organ Dysfunction score at ICU discharge (OR 1.45, 95% CI 1.1–1.9) and age (OR 1.06, 95% CI 1.02–1.12) were independently associated with RBC transfusion after ICU stay. Haemoglobin level at discharge predicted the need for delayed RBC transfusion. Use of vasopressors (OR 0.01, 95%CI 0.001–0.17) and haemoglobin level at discharge from the ICU (OR 0.02, 95% CI 0.007–0.09; P < 0.001) were strong independent predictors of transfusion of RBC 1 week after ICU discharge. Conclusion Sepsis, underlying conditions, unresolved organ failures and haemoglobin level at discharge were related to an increased risk for RBC transfusion after ICU stay. We suggest that strategies to prevent transfusion should focus on homogeneous subgroups of patients and take into account post-ICU needs for RBC transfusion. PMID:16965637

The objective of this study was to examine the effect of post-fusion treatment of somatic cell nuclear transfer (SCNT) oocytes with the proteasomal inhibitor MG132 on maturation promoting factor (MPF) activity, nuclear remodeling, embryonic development, and gene expression of cloned pig embryos. Immediately after electrofusion, SCNT oocytes were treated with MG132 and/or caffeine for 2 hr, vanadate for 0.5 hr, or vanadate for 0.5 hr followed by MG132 for 1.5 hr. Of the MG132 concentrations tested (0-5 microM), the 1 microM concentration showed a higher rate of blastocyst formation (25.9%) than 0 (14.2%), 0.5 (16.9%), and 5 microM (16.9%). Post-fusion treatment with MG132, caffeine, and both MG132 and caffeine improved blastocyst formation (22.1%, 21.4%, and 24.4%, respectively), whereas vanadate treatment inhibited blastocyst formation (6.5%) compared to the control (11.1%). When examined 2 hr after fusion and 1 hr after activation, MPF activity remained at a higher (P fusion with caffeine and/or MG132, but it was decreased by vanadate. The rate of oocytes showing premature chromosome condensation was not altered by MG132 but was decreased by vanadate treatment. In addition, formation of single pronuclei was increased by MG132 compared to control and vanadate treatment. MG132-treated embryos showed increased expression of POU5F1, DPPA2, DPPA3, DPPA5, and NDP52l1 genes compared to control embryos. Our results demonstrate that post-fusion treatment of SCNT oocytes with MG132 prevents MPF degradation and increases expression of transcription factors in SCNT embryos, which are necessary for normal development of SCNT embryos.

Full Text Available There is increasing awareness of the impact of post-traumatic stress disorder (PTSD on physical health, particularly cardiovascular disease. We review the literature on the role of trauma in the development of cardiovascular risk factors and disease, aftermath of a cardiac event, and risk for recurrence in cardiac patients. We explore possible mechanisms to explain these relationships, as well as appropriate assessment and treatment strategies for this population. Our main conclusion is that screening and referral for appropriate treatments are important given the high prevalence rates of PTSD in cardiac populations and the associated impact on morbidity and mortality.

OBJECT The authors performed a prospective study to define the prevalence and microbiological characteristics of infections in patients undergoing craniotomy and to clarify the risk factors for post-craniotomy meningitis. METHODS Patients older than 18 years who underwent nonstereotactic craniotomies between January 2006 and December 2008 were included. Demographic, clinical, laboratory, and microbiological data were systemically recorded. Patient characteristics, craniotomy type, and pre- and postoperative variables were evaluated as risk factors for meningitis RESULTS Three hundred thirty-four procedures were analyzed (65.6% involving male patients). Traumatic brain injury was the most common reason for craniotomy. Almost 40% of the patients developed at least 1 infection. Ventilator-associated pneumonia (VAP) was the most common infection recorded (22.5%) and Acinetobacter spp. were isolated in 44% of the cases. Meningitis was encountered in 16 procedures (4.8%), and CSF cultures were positive for microbial growth in 100% of these cases. Gram-negative pathogens (Acinetobacter spp., Klebsiella spp., Pseudomonas aeruginosa, Enterobacter cloaceae, Proteus mirabilis) represented 88% of the pathogens. Acinetobacter and Klebsiella spp. demonstrated a high percentage of resistance in several antibiotic classes. In multivariate analysis, the risk for meningitis was independently associated with perioperative steroid use (OR 11.55, p = 0.005), CSF leak (OR 48.03, p meningitis in this study. Ventilator-associated pneumonia was the most common infection overall. The offending pathogens presented a high level of resistance to several antibiotics.

Full Text Available Pancreatitis is the most common complication of endoscopic retrograde cholangiopancreatography (ERCP. Several patients´ or procedure related risk factors for post-ERCP pancreatitis (PEP have been suggested. The aim of this study was to validate the risk factors for PEP in a high-volume center.All patients undergoing first time ERCP at a tertiary referral center between December 2010 and October 2013 were retrospectively included. PEP was defined according to the Atlanta Classification.344 patients were included in the final analysis. The risk to develop PEP was increased in patients with chronic pancreatitis (odds ratio 3.7 and after inadvertent cannulation of the pancreatic duct (odds ratio 2.2, which occurred in 26.5% of the patients. Inadvertent cannulation occurred significantly more frequently in patients with difficult cannulation of the papilla duodeni major (odds ratio 12.7; p<0.001. ERCP on call was associated with an increased risk for difficult cannulation (odds ratio 3.0.Inadvertent cannulation of the pancreatic duct is a procedure related risk factor for PEP. Measurements on preventing inadvertent cannulation of the pancreatic duct should be established and studies on prophylactic measurements should focus particularly on patients with inadvertent cannulation of the pancreatic duct.

Schick, Andreas; Miller, Kathleen L; Lanthier, Michael; Dal Pan, Gerald; Nardinelli, Clark

An important goal in drug regulation is understanding serious safety issues with new drugs as soon as possible. Achieving this goal requires us to understand whether information provided during the Food and Drug Administration (FDA) drug review can predict serious safety issues that are usually identified after the product is approved. However, research on this topic remains understudied. In this paper, we examine whether any pre-marketing drug characteristics are associated with serious post-marketing safety actions. We study this question using an internal FDA database containing every new small molecule drug submitted to the FDA's Center for Drug Evaluation and Research (CDER) on or after November 21, 1997, and approved and commercially launched before December 31, 2009. Serious post-marketing safety actions include whether these drugs ever experienced either a post-marketing boxed warning or a withdrawal from the market due to safety concerns. A random effects logistic regression model was used to test whether any pre-marketing characteristics were associated with either post-marketing safety action. A total of 219 new molecular entities were analyzed. Among these drugs, 11 experienced a safety withdrawal and 30 received boxed warnings by July 31, 2016. Contrary to prevailing hypotheses, we find that neither clinical trial sample sizes nor review time windows are associated with the addition of a post-marketing boxed warning or safety withdrawal. However, we do find that new drugs approved with either a boxed warning or priority review are more likely to experience post-marketing boxed warnings. Furthermore, drugs approved with boxed warnings tend to receive post-marketing boxed warnings resulting from new safety information that are unrelated to the original warning. Drugs approved with a boxed warning are 3.88 times more likely to receive a post-marketing boxed warning, while drugs approved with a priority review are 3.51 times more likely to receive a post

The aim of the present study is to investigate the effects of exogenous fibroblast growth factor (FGF)9 on the progression of post-traumatic osteoarthritis (OA). The expression of FGF9 in articular cartilage with OA is detected by immunohistochemistry (IHC). The effects of intra-articular exogenous FGF9 injection on post-traumatic OA induced by the destabilization of the medial meniscus (DMM) surgery are evaluated. Cartilage changes and osteophyte formation in knee joints are investigated by histological analysis. Changes in subchondral bone are evaluated by microcomputed tomography (micro-CT). The effect of exogenous FGF9 on an interleukin-1β (IL-1β)-induced ex vivo OA model of human articular cartilage tissues is also evaluated. FGF9 expression was down-regulated in articular chondrocytes of OA but ectopically induced at sites of osteophyte formation. Intra-articular injection of exogenous FGF9 attenuated articular cartilage degradation in mice after DMM surgery. Exogenous FGF9 suppressed collagen X and MMP13 expressions in OA cartilage, while promoted collagen II expression. Similar results were observed in IL-1β-induced ex vivo OA model. Intra-articular injection of FGF9 had no significant effect on the subchondral bone of knee joints after DMM surgery, but aggravated osteophyte formation. The expressions of SOX9 and collagen II, and cell proliferation were up-regulated at sites of initial osteophyte formation in mice with exogenous FGF9 treatment. Intra-articular injection of exogenous FGF9 delays articular cartilage degradation in post-traumatic OA, while aggravates osteophyte formation. Copyright © 2016. Published by Elsevier Ltd.

Risk analysis of cold ischemia time (CIT) in liver transplantation has largely focused on patient and graft survival. Post-transplant length of stay is a sensitive marker of morbidity and cost. We hypothesize that CIT is a risk factor for post-transplant prolonged length of stay (PLOS) and aim to conduct an hour-by-hour analysis of CIT and PLOS. We retrospectively reviewed all adult, first-time liver transplants between March 2002 and September 2016 in the United Network for Organ Sharing database. 67,426 recipients were categorized by hourly CIT increments. Multivariable logistic regression of PLOS (defined as > 30 days), CIT groups, and an extensive list of confounding variables was performed. Linear regression between length of stay and CIT as continuous variables was also performed. CIT 1-6 hours was protective against PLOS, while CIT greater than 7 hours was associated with increased odds for PLOS. The lowest odds for PLOS were observed with 1-2 (odds ratio (OR) = 0.65, 95% confidence interval (CI) 0.45-0.92) and 2-3 hours (OR = 0.65, 95% CI 0.55-0.78) of CIT. OR for PLOS steadily increased with increasing CIT, reaching the greatest odds for PLOS with 13-14 hours (OR = 2.05, 95% CI 1.57-2.67) and 15-16 hours (OR = 2.06, 95% CI 1.27-3.33) of CIT. Linear regression revealed a positive correlation between length of stay and cold ischemia time with a correlation coefficient of +0.35 (p < 0.001). Post-liver transplant length of stay is sensitive to CIT, with substantial increase in the odds of PLOS observed with nearly every additional hour of cold ischemia. We conclude that CIT should be minimized to protect against the morbidity and cost associated with post-transplant PLOS. This article is protected by copyright.

Granulocyte colony-stimulating factor (G-CSF) is now widely used for stem cell mobilization. We evaluated the role of post-G-CSF white blood cell (WBC) counts and donor factors in predicting adverse events and yields associated with mobilization. WBC counts were determined at baseline, after the third and the fifth dose of G-CSF in 476 healthy donors. Donors with WBC ≥ 50 × 10(3)/μL post the third dose of G-CSF experienced more fatigue, myalgia/arthralgia, and chills, but final post-G-CSF CD34(+) cell counts were similar. Although the final CD34(+) cell count was higher in donors with WBC ≥ 50 × 10(3)/μL post the fifth G-CSF, the incidence of side effects was similar. Females more frequently experienced headache, nausea/anorexia, vomiting, fever, and lower final CD34(+) cell count than did males. Donors with body mass index (BMI) ≥ 25 showed higher incidences of sweat and insomnia as well as higher final CD34(+) cell counts. Donor receiving G-CSF ≥ 10 μg/kg tended to experience bone pain, headache and chills more frequently. Multivariate analysis indicated that female gender is an independent factor predictive of the occurrence of most side effects, except for ECOG > 1 and chills. Higher BMI was also an independent predictor for fatigue, myalgia/arthralgia, and sweat. Higher G-CSF dose was associated with bone pain, while the WBC count post the third G-CSF was associated with fatigue only. In addition, one donor in the study period did not complete the mobilization due to suspected anaphylactoid reaction. Observation for 1 h after the first injection of G-CSF is required to prevent complications from unpredictable side effects.

The assessment of science: the relative merits of post-publication review, the impact factor, and the number of citations.

Eyre-Walker, Adam; Stoletzki, Nina

The assessment of scientific publications is an integral part of the scientific process. Here we investigate three methods of assessing the merit of a scientific paper: subjective post-publication peer review, the number of citations gained by a paper, and the impact factor of the journal in which the article was published. We investigate these methods using two datasets in which subjective post-publication assessments of scientific publications have been made by experts. We find that there are moderate, but statistically significant, correlations between assessor scores, when two assessors have rated the same paper, and between assessor score and the number of citations a paper accrues. However, we show that assessor score depends strongly on the journal in which the paper is published, and that assessors tend to over-rate papers published in journals with high impact factors. If we control for this bias, we find that the correlation between assessor scores and between assessor score and the number of citations is weak, suggesting that scientists have little ability to judge either the intrinsic merit of a paper or its likely impact. We also show that the number of citations a paper receives is an extremely error-prone measure of scientific merit. Finally, we argue that the impact factor is likely to be a poor measure of merit, since it depends on subjective assessment. We conclude that the three measures of scientific merit considered here are poor; in particular subjective assessments are an error-prone, biased, and expensive method by which to assess merit. We argue that the impact factor may be the most satisfactory of the methods we have considered, since it is a form of pre-publication review. However, we emphasise that it is likely to be a very error-prone measure of merit that is qualitative, not quantitative.

A partir de la auditoría de las historias clínicas se obtuvieron los indicadores siguientes del pronóstico del niño quemado: superficie corporal quemada, tiempo de estadía, por ciento de pérdida de peso y mortalidad. De la misma forma se obtuvo la información acerca del tipo de soporte nutrimental metabólico empleado durante el tratamiento. Resultados: el tipo de soporte nutrimental metabólico más empleado fue el mixto, en el que se combinan las modalidades enteral y parenteral periférica, que abarcó al 52 % de los pacientes tratados. Los niños con menor por ciento de pérdida de peso (inferior al 10 % recibieron la forma enteral exclusiva (53,1 % de los casos tratados; en el 37,4 % el soporte fue mixto, pero usando la modalidad periférica de uso parenteral. Conclusiones: la estrategia nutrimental empleada en el niño quemado puede modificar algunos indicadores del pronóstico y debe ser una prioridad terapéutica para prevenir el deterioro clínico de estos pacientes.

Highlights: → We performed comprehensive PTM analysis for HNF4α protein. → We identified 8 PTMs in HNF4α protein including newly identified PTMs. → Among them, we found acetylation at lysine 458 was one of the prime PTMs for HNF4α function. → Acetylation at lysine 458 was inhibitory for HNF4α transcription function. → This modification fluctuated in response to extracellular condition. -- Abstract: To investigate the role of post-translational modifications (PTMs) in the hepatocyte nuclear factor 4α (HNF4α)-mediated transcription, we took a comprehensive survey of PTMs in HNF4α protein by massspectrometry and identified totally 8 PTM sites including newly identified ubiquitilation and acetylation sites. To assess the impact of identified PTMs in HNF4α-function, we introduced point mutations at the identified PTM sites and, tested transcriptional activity of the HNF4α. Among the point-mutations, an acetylation site at lysine 458 was found significant in the HNF4α-mediated transcriptional control. An acetylation negative mutant at lysine 458 showed an increased transcriptional activity by about 2-fold, while an acetylation mimic mutant had a lowered transcriptional activation. Furthermore, this acetylation appeared to be fluctuated in response to extracellular nutrient conditions. Thus, by applying an comprehensive analysis of PTMs, multiple PTMs were newly identified in HNF4α and unexpected role of an HNF4α acetylation could be uncovered.

Se determinaron los factores limitantes de la polinización natural de un cultivo de híbridos de cacao de 15 años de edad y se estimaron las variaciones en las condiciones de la polinización de acuerdo con la localidad, mediante la confrontación de los resultados obtenidos en este trabajo con aquellos encontrados para la región de Granada (Meta, en el mismo piedemonte llanero colombiano, La mayor diferencia entre las dos localidades fue la cantidad de polen aportado sobre los estilos, siendo el índice de rareza de polen (A para Guamal de 0,7, 10 cual sugiere unas condiciones de polinización intermedias en comparación con el hallado en Granada que fue de 1,07, Y que explica el deficiente llenado de las mazorcas con granos. Las probabilidades de formación y producción  de frutos de cacao fueron similares en las dos localidades según los val ores encontrados para Xw y Xm. La fertilidad en condiciones de polinización natural para las dos local localidades fue baja y la distribución de granos por mazorca confirmo las fallas en la polinización de las flores, siendo el problema de subpolinización más acentuado en Granada que en Guamal. Las condiciones de polinización variaron notablemente de una cosecha a la otra y también entre localidades, siendo una de las causas de la baja producción de cacao en la región.

Growth of New Firms: Which Factors Influence Post-Entry Performance? An Empirical Analysis Based on Swiss Firm Data

The aim of this study is to shed light on the factors which determine the post-entry performance of new firms. It is often argued that new firms are the driving force of structural changes and sometimes they are even characterized as an “engine” of economic growth. Nevertheless, the empirical evidence is mixed. Taking into account the high exit rate of new firms, a specific founding cohort does not contribute substantially to new jobs. In this paper, we analyse the contribution of new firms c...

Full Text Available The CoPanFlu-France cohort of households was set up in 2009 to study the risk factors for infection by the pandemic influenza virus (H1N1pdm in the French general population. The authors developed an integrative data-driven approach to identify individual, collective and environmental factors associated with the post-seasonal serological H1N1pdm geometric mean titer, and derived a nested case-control analysis to identify risk factors for infection during the first season. This analysis included 1377 subjects (601 households. The GMT for the general population was 47.1 (95% confidence interval (CI: 45.1, 49.2. According to a multivariable analysis, pandemic vaccination, seasonal vaccination in 2009, recent history of influenza-like illness, asthma, chronic obstructive pulmonary disease, social contacts at school and use of public transports by the local population were associated with a higher GMT, whereas history of smoking was associated with a lower GMT. Additionally, young age at inclusion and risk perception of exposure to the virus at work were identified as possible risk factors, whereas presence of an air humidifier in the living room was a possible protective factor. These findings will be interpreted in light of the longitudinal analyses of this ongoing cohort.

We retrospectively investigated the incidence and risk factors for transfusion-related acute lung injury (TRALI) among patients transfused for post-partum hemorrhage (PPH). We identified a series of 71 consecutive patients with PPH requiring the urgent transfusion of three or more red blood cell (RBC) units, with or without transfusion of fresh frozen plasma (FFP) and/or platelets (PLT). Clinical records were then retrieved and examined for respiratory distress events. According to the 2004 consensus definition, cases of new-onset hypoxemia, within 6 hours after transfusion, with bilateral pulmonary changes, in the absence of cardiogenic pulmonary edema were identified as TRALI. If an alternative risk factor for acute lung injury was present, possible TRALI was diagnosed. Thirteen cases of TRALI and 1 case of possible TRALI were identified (overall incidence 19.7%). At univariate analysis, patients with TRALI received higher number of RBC, PLT and FFP units and had a longer postpartum hospitalization. Among the diseases occurring in pregnancy- and various pre-existing comorbidities, only gestational hypertension and pre-eclampsia, significantly increased the risk to develop TRALI (p = 0.006). At multivariate analysis including both transfusion- and patient-related risk factors, pregnancy-related, hypertensive disorders were confirmed to be the only predictors for TRALI, with an odds ratio of 27.7 ( 95% CI 1.27-604.3, p=0.034). Patients suffering from PPH represent a high-risk population for TRALI. The patients with gestational hypertension and pre-eclampsia, not receiving anti-hypertensive therapy, have the highest risk. Therefore, a careful monitoring of these patients after transfusions is recommended.

Post-mastectomy reconstruction is a critical component of high-quality breast cancer care. Prior studies demonstrate socioeconomic disparity in receipt of reconstruction. Our objective was to evaluate trends in receipt of immediate reconstruction and examine socioeconomic factors associated with reconstruction in a contemporary cohort. Using the National Cancer Database, we identified women rates (2004-2013) for the overall cohort and stratified by socioeconomic factors were examined using Join-point regression analysis, and annual percentage change (APC) was calculated. We then restricted our sample to a contemporary cohort (2010-2013, n = 145,577). Multivariable logistic regression identified socioeconomic factors associated with immediate reconstruction. Average adjusted predicted probabilities of receiving reconstruction were calculated. Immediate reconstruction rates increased from 27 to 48%. Although absolute rates of reconstruction for each stratification group increased, similar APCs across strata led to persistent gaps in receipt of reconstruction. On multivariable logistic regression using our contemporary cohort, race, income, education, and insurance type were all strongly associated with immediate reconstruction. Patients with the lowest predicted probability of receiving reconstruction were patients with Medicaid who lived in areas with the lowest rates of high-school graduation (Black 42.4% [95% CI 40.5-44.3], White 45.7% [95% CI 43.9-47.4]). Although reconstruction rates have increased dramatically over the past decade, lower rates persist for disadvantaged patients. Understanding how socioeconomic factors influence receipt of reconstruction, and identifying modifiable factors, are critical next steps towards identifying interventions to reduce disparities in breast cancer surgical care.

Quality of life (QOL) reflects the individual's perception of the position within living contexts. This study was done to describe pre- and post-stroke QOLs of stroke survivors. A prospective longitudinal study was done among stroke survivors admitted to 13 hospitals in the western province of Sri Lanka. The calculated sample size was 260. The pre-stroke and post-discharge one-month QOL was gathered using short form-36 (SF-36) QOL tool. SF-36 includes questions on eight domains: general health, physical functioning, pain, role limitation due to physical problems, social functioning, vitality, role limitations due to emotional problems, and mental health. Univariate analysis was followed by determining the independent risk factors through multivariate analysis. The response rate was 81%. The disability was measured by the modified Rankin scale which ranges from 0 (no symptoms) to 6 (fatal outcome). The median (IQR) disability score was 4 (3 to 5). The post-discharge QOL scores were significantly lower than pre-stroke values (p role limitation-physical domains), female gender (for physical functioning and pain domains), lower health infrastructure (for general health, vitality, and mental health domains), lower education (for pain domain), higher disability (for general health, physical functioning, vitality, social functioning, and mental health domains), and hypercholesterolemia (for role limitation-emotional domain). Stroke survivors have not regained their pre-stroke QOL at 1 month following the hospital discharge irrespective of income level and pre-stroke QOL. Higher pre- and post-stroke QOLs are associated with better statuses of social determinants of health.

Postpartum depression (PPD) is a public health problem with high prevalence in Chile. Many factors are associated with PPD. To analyze the factors associated with the incidence of depressive symptoms (SD) in women with low obstetric risk. Cross-sectional analytical study on a sample of 105 postpartum women with low obstetric risk assessed by the Edinburgh Depression Scale at the eighth week postpartum. A 37% prevalence of depressive symptoms was found. Univariate analysis showed that the perception of family functioning, overcrowding and number of siblings, were significantly associated with postpartum depressive symptoms. A multiple regression model only accepted family functioning as a predictor of depression. Perception of family functioning was the only variable that explained in part the presence of depressive symptoms in women with low obstetric risk.

Although post-polypectomy bleeding is the most frequent complication after colonoscopic polypectomy, only few studies have investigated the incidence of bleeding prospectively. The aim of this study was to investigate the incidence of delayed post-polypectomy bleeding and its associated risk factors prospectively. Patients who underwent colonoscopic polypectomy at Kangbuk Samsung Hospital from January 2013 to December 2014 were prospectively enrolled in this study. Trained nurses contacted patients via telephone 7 and 30 days after polypectomy and completed a standardized questionnaire regarding the development of bleeding. Delayed post-polypectomy bleeding was categorized as minor or major and early or late bleeding. Major delayed bleeding was defined as a > 2-g/dL drop in the hemoglobin level, requiring hospitalization for control of bleeding or blood transfusion; late delayed bleeding was defined as bleeding occurring later than 24 h after polypectomy. A total of 8175 colonoscopic polypectomies were performed in 3887 patients. Overall, 133 (3.4%) patients developed delayed post-polypectomy bleeding. Among them, 90 (2.3%) and 43 (1.1%) patients developed minor and major delayed bleeding, respectively, and 39 (1.0%) patients developed late delayed bleeding. In the polyp-based multivariate analysis, young age ( 10 mm (OR 2.45; 95% CI 1.38-4.36) were significant risk factors for major delayed bleeding, while young age (< 50 years; OR 2.6; 95% CI 1.35-5.12) and immediate bleeding (OR 3.3; 95% CI 1.49-7.30) were significant risk factors for late delayed bleeding. Young age, aspirin use, polyp size, and immediate bleeding were found to be independent risk factors for delayed post-polypectomy bleeding.

Materiales y métodos: Se estudiaron 22 pacientes, distribuidos en 16 familias, del “Programa de atención integral a pacientes con fibrosis quística” de la Universidad de Cartagena. Se recopiló información acerca de las condiciones de vivienda del grupo familiar y se evaluaron aspectos fenotípicos hereditarios, y se construyeron genealogías para esta enfermedad. Resultados: El análisis de pedigríes reveló lo siguiente: en ocho familias (67%, los individuos afectados presentan rasgos caucásicos; en cinco familias (42% se reconoce existencia de ancestros europeos; en dos familias (17% existe consaguinidad. En relación con el aspecto ambiental, se encontró que 33% de las familias estudiadas habitan viviendas en malas condiciones. Conclusiones: Entre las familias de los pacientes con fibrosis quística de la ciudad de Cartagena detectados en este estudio se verifica la transmisión hereditaria autosómica recesiva, se confirma el mestizaje de nuestras poblaciones. La reincidencia de enfermos y la consanguinidad en varias familias denota la falta de asesoramiento genético y el desconocimiento de la evolución de la enfermedad por su grupo familiar. Estos resultados pueden ser el punto de partida de estudios más amplios que sirvan de fundamento para la implementación de políticas tendientes a reducir la frecuencia y severidad de la enfermedad a nivel local y nacional.

In 2008, 5 years after the Liberian civil war ended, there were an estimated 340,000 orphans in Liberia, 18 % of the total child population of the country. Given that children make up half the population and that these children experienced significant trauma and loss both through direct exposure to the war and then to the Ebola epidemic, and indirectly as a result of the trauma experienced by their parents, the recovery of these children is essential to the recovery of the nation as a whole. The goal of this research was to identify factors contributing to resilience among youth in post-conflict Liberia. Resilience was defined as evidence of adaptive functioning and psychological health. Seventy-five young people (age 13-18) in the capital city of Monrovia, Liberia were recruited in 2012. Semi-structured interviews were conducted, and demographic data were collected. Interviews were then transcribed and coded thematically. Forty-six of the participants were attending school, and 29 were not enrolled in school. Youth enrolled in school demonstrated greater adaptive functioning. This was particularly true for boys in any school setting and girls attending private school. Youth not attending school were more likely to have lost family members or become estranged from them, and many were also engaging in substance use. Emotion regulation, cognitive flexibility, agency, social intelligence and, in some cases, meaning-making were found in participants who showed resilient outcomes. Caregiver relationships mediate the development of psychological capacities that impact resilience. These findings suggest that youth who have lost a caregiver, many of whom are not attending school, are experiencing a significant ongoing burden in terms of their daily functioning and psychological health in the post-war period and should be the focus of further study and intervention targeting substance use and community reintegration.

Full Text Available La publicación de la quinta edición del DSM ha avivado un debate iniciado tiempo atrás, desde el anuncio de los cambios en los criterios de diagnóstico propuestos por la APA. En este artículo se analizan algunas de estas modificaciones. Se plantean aspectos interesantes y acertados, como la inclusión de la dimensionalidad, tanto en las clases diagnósticas como en algunos trastornos, la incorporación de un espectro obsesivo-compulsivo o la desaparición de los subtipos de esquizofrenia. También se analizan otros aspectos más controvertidos como la consideración del síndrome de psicosis atenuada, la descripción de un trastorno depresivo persistente, la reordenación en trastornos de síntomas somáticos los clásicos trastornos somatoformes, o el mantenimiento de los tres grandes grupos de trastornos de la personalidad, siempre insatisfactorios, junto con un planteamiento anunciado, pero marginal, de la perspectiva dimensional de las alteraciones de la personalidad. La nueva clasificación del DSM-5 abre numerosos interrogantes acerca de la validez que se pretende mejorar en el diagnóstico, en esta ocasión, asumiendo un planteamiento más cercano a la neurología y la genética que a la psicopatología clínica.

Recent advances in the risk factors, diagnosis and management of Epstein-Barr virus post-transplant lymphoproliferative disease.

Aguayo-Hiraldo, Paibel; Arasaratnam, Reuben; Rouce, Rayne H

Fifty years after the first reports of Epstein-Barr virus (EBV)-associated endemic Burkitt's lymphoma, EBV has emerged as the third most prevalent oncogenic virus worldwide. EBV infection is associated with various malignancies including Hodgkin and non-Hodgkin lymphoma, NK/T-cell lymphoma and nasopharyngeal carcinoma. Despite the highly specific immunologic control in the immunocompetent host, EBV can cause severe complications in the immunocompromised host (namely, post-transplant lymphoproliferative disease). This is particularly a problem in patients with delayed immune reconstitution post-hematopoietic stem cell transplant or solid organ transplant. Despite advances in diagnostic techniques and treatment algorithms allowing earlier identification and treatment of patients at highest risk, mortality rates remain as high as 90% if not treated early. The cornerstones of treatment include reduction in immunosuppression and in vivo B cell depletion with an anti-CD20 monoclonal antibody. However, these treatment modalities are not always feasible due to graft rejection, emergence of graft vs. host disease, and toxicity. Newer treatment modalities include the use of adoptive T cell therapy, which has shown promising results in various EBV-related malignancies. In this article we will review recent advances in risk factors, diagnosis and management of EBV-associated malignancies, particularly post-transplant lymphoproliferative disease. We will also discuss new and innovative treatment options including adoptive T cell therapy as well as management of special situations such as chronic active EBV and EBV-associated hemophagocytic lymphohistiocytosis.

Ablative laser resurfacing is considered to be the main therapeutic option for the treatment of wrinkles and acne scarring. However, in Asians, post-inflammatory hyperpigmentation (PIH) is a common adverse effect of laser resurfacing. Fractional resurfacing is a new concept of skin rejuvenation whereby zones of micro thermal injury are generated in the skin with the use of a 1,540-nm laser. The risk and prevalence of hyperpigmentation in dark-skinned patients using this approach have not been studied. To assess the prevalence and risk factors of PIH that is associated with the use of fractional resurfacing in Asians. A retrospective study of 37 Chinese patients who were treated with fractional resurfacing for acne scarring, skin rejuvenation, and pigmentation was carried out. In all of the cases, pre- and post-treatment clinical photographs (from standardized and cross-polarized views) were taken using the Canfield CR system. Two independent observers assessed the photographs. A prospective study of treatments of nine different density and energy levels that were applied to the forearms of 18 volunteers was also performed. Clinical photographs were assessed pre- and post-treatment for evidence of PIH. In the retrospective study, 119 treatment sessions were performed. Sixty-eight treatment sessions were high energy, low density; 51 sessions were low energy, high density. Patients who underwent a high energy but low-density treatment (range of energy 7-20 mJ; average energy 16.3 mJ, 1,000 MTZ) were associated with a lower prevalence of generalized PIH (7.1% vs. 12.4%) than those who underwent a low energy but high-density (range of energy 6-12 mJ; average energy 8.2 mJ, 2,000 MTZ) treatment. However, the difference was not statistically significant. Localized PIH occurred in the peri-oral area among patients who did not receive air cooling as an adjunctive therapy. Both the density and energy of the treatment determines the risk of PIH in dark-skinned patients

The purpose of this study was to assess factors associated with Escherichia coli (E. coli) contamination in rural households in Cambodia that have adopted household water treatment. The following factors were significantly associated (α E. coli contamination: cleaning the drinking vessel with untreated water, not drying the cup (with a cloth), accessing treated water by the use of a scoop (ref: using a tap), having more than one untreated water storage container, having an untreated water storage container that appeared dirty on the outside, and cows living within 10 m of the household. This study provides further evidence confirming previous studies reporting an association between inadequate cleanliness of water storage containers and household drinking water contamination, and identifies practical recommendations statistically associated with reduced post-treatment E. coli contamination in the household setting in rural Cambodia.

Yoon, Sunmoo; Gutierrez, Jose

Disability is a potential risk for stroke survivors. This study aims to identify disability risk factors associated with stroke and their relative importance and relationships from a national behavioral risk factor dataset. Data of post-stroke individuals in the U.S (n=19,603) including 397 variables were extracted from a publically available national dataset and analyzed. Data mining algorithms including C4.5 and linear regression with M5s methods were applied to build association models for post-stroke disability using Weka software. The relative importance and relationship of 70 variables associated with disability were presented in infographics for clinicians to understand easily. Fifty-five percent of post-stroke patients experience disability. Exercise, employment and satisfaction of life were relatively important factors associated with disability among stroke patients. Modifiable behavior factors strongly associated with disability include exercise (OR: 0.46, PData mining is promising to discover factors associated with post-stroke disability from a large population dataset. The findings can be potentially valuable for establishing the priorities for clinicians and researchers and for stroke patient education. The methods may generalize to other health conditions.

To evaluate the influence of post design and roughness and cement system (dual- or self-cured) on the retention of glass fibre posts. Two tapered and smooth posts (Exacto Cônico No. 2 and White Post No. 1) and two parallel-sided and serrated posts (Fibrekor 1.25 mm and Reforpost No. 2) were adhesively luted with two different resin cements--a dual-cured (Rely-X ARC) and a self-cured (Cement Post)--in 40 single-rooted teeth. The teeth were divided into eight experimental groups (n = 5): PFD--Parallel-serrated-Fibrekor/dual-cured; PRD--Parallel-serrated-Reforpost/dual-cured; TED--Tapered-smooth-Exacto Cônico/dual-cured; TWD--Tapered-smooth-White Post/dual-cured; PFS--Parallel-serrated-Fibrekor/self-cured; PRS--Parallel-serrated-Reforpost/self-cured; TES--Tapered-smooth-Exacto Cônico/self-cured; TWS--Tapered-smooth-White Post/self-cured. The specimens were submitted to a pull-out test at a crosshead speed of 0.5 mm min(-1). Data were analysed using analysis of variance and Bonferroni's multiple comparison test (alpha = 0.05). Pull-out results (MPa) were: PFD = 8.13 (+/-1.71); PRD = 8.30 (+/-0.46); TED = 8.68 (+/-1.71); TWD = 9.35 (+/-1.99); PFS = 8.54 (+/-2.23); PRS = 7.09 (+/-1.96); TES = 8.27 (+/-3.92); TWS = 7.57 (+/-2.35). No statistical significant difference was detected for posts and cement factors and their interaction. The retention of glass fibre posts was not affected by post design or surface roughness nor by resin cement-curing mode. These results imply that the choice for serrated posts and self-cured cements is not related to an improvement in retention.

Stress in accident and post-accident management at Chernobyl

International Nuclear Information System (INIS)

Girard, P.; Dubreuil, G.H.

1996-01-01

The effects of the Chernobyl nuclear accident on the psychology of the affected population have been much discussed. The psychological dimension has been advanced as a factor explaining the emergence, from 1990 onwards, of a post-accident crisis in the main CIS countries affected. This article presents the conclusions of a series of European studies, which focused on the consequences of the Chernobyl accident. These studies show that the psychological and social effects associated with the post-accident situation arise from the interdependency of a number of complex factors exerting a deleterious effect on the population. We shall first attempt to characterise the stress phenomena observed among the population affected by the accident. Secondly, we will be presenting an anlysis of the various factors that have contributed to the emerging psychological and social features of population reaction to the accident and in post-accident phases, while not neglecting the effects of the pre-accident situation on the target population. Thirdly, we shall devote some initial consideration to the conditions that might be conducive to better management of post-accident stress. In conclusion, we shall emphasise the need to restore confidence among the population generally. (Author)

Identification of modifying factors that influence the development of post-concussion syndrome (PCS) following sport-related concussion (SRC) has drawn considerable interest. In this pilot study, we investigate the effect of team vs. individual sport participation on the development of PCS in a sample of 136 high school and college student-athletes. Controlling for several confounding variables, we employed a binary logistic regression and chi-squared test. Results of this pilot study indicate that participation in team versus individual sport is not a significant factor in the development of PCS. The identification of other forms of protective mechanisms is discussed.

The sustainable urban development growth in the ASEAN region has accelerated tremendously. More demand on the sustainable development has led to bigger market driven certified green neighborhood and buildings. However, there is a lack of post-occupancy evaluation study conducted in assessing the end-users perspective on the certified sustainable neighborhood development. This paper aims to investigate the end-users point of view on sustainable dimension pillar (SDP) adaptation based on environment dimension, social dimension and economic dimension using Post-Occupancy Evaluation Model (POEM) framework. The research methodology employed stakeholders-Inclusion Approach survey questionnaires in order to obtained the sustainable dimensional adaptation score. The results show that there is sustainable dimension gap in POEM evaluation, hence, suggested the pre- occupancy criteria did not fulfill the SDP adaptation and pre-occupancy criteria and variables if differ from post-occupancy criteria and variables.

Symptoms of both depression and Post-Traumatic Stress Disorder (PTSD) are prevalent among first-time mothers following birth. However, the direction of the association between the two types of symptoms is unclear. Ninety six first-time mothers giving birth via vaginal delivery (N=38), emergency C-Section (N=27) and planned C-Section (N=21) were assessed for depression and PTSD twice: Six weeks post-partum and six-weeks later. Cross-lagged Structural Equation Modeling (SEM) analyses revealed a prospective effect of depressive symptoms on PTSD symptoms. No moderating factors were identified. A relatively modest sample size and only two assessment waves. An early detection and intervention with symptoms of post-partum depression might also prevent the development of PTSD symptoms.

La nutrición es uno de los factores de influencia más efectiva sobre la productividad de los árboles frutales. Al contrario del análisis de suelo, el análisis foliar o de tejidos vegetales reune todos los factores que influyen sobre la disponibilidad de los nutrientes. Un alto contenido de un nutriente en el árbol puede reflejar el suplemento inadecuado de otro nutriente. Las relaciones sinérgicas y antagónicas entre los nutrientes se deben tener en cuenta al interpretar el análisis de tejidos vegetales. El crecimiento del árbol es una función de dos variables de nutrición, la intensidad y el balance. Por tanto, en este ensayo se evaluaron mensualmente las relaciones e interacciones entre los nutrientes en hojas y frutos de árboles de manzano ‘Anna’, cultivados en un suelo áido en los altiplanos tropicales. Las evaluaciones se hicieron desde 16 dís despué de plena floració (ddpf hasta la cosecha. El contenido de nutrientes en ramas se evaluóantes y despué de la temporada de crecimiento, al momento de defoliar y en la éoca de cosecha, respectivamente.

To identify the risk factors for post-traumatic amnesia (PTA) and to document the incidence of PTA after mild traumatic brain injuries. This was a prospective study, affecting mild TBI (mTBI) (Glasgow Coma Scale 14-15) cases attending to the Emergency Department between January 2009 and April 2012 (40 months duration). Patients were divided into two groups (Group A: without PTA, and Group B: with PTA, and they were assessed according to the risk factors. A total of 1762 patients (males: 1002, 56.8%) were meeting study inclusion criteria [Group A: n = 1678 (83.8%), Group B: n = 84 (4.2%)]. Age, CT findings: (traumatic focal HCs in the frontal and temporal lobes or more diffuse punctate HCs, and skull base fractures), anticoagulation therapy and seizures were independent factors of PTA. There was no statistically significant correlation between PTA and sex, convexity fractures, stroke event, mechanism of mTBI (fall +/or beating), hypertension, coronary heart disease, chronic smokers and diabetes (p > 0.005). CT findings: (traumatic focal HCs in the frontal and temporal lobes or more diffuse punctate HCs and skull base fractures), age, seizures and anticoagulation/antiplatelet therapy, were independent factors of PTA and could be used as predictive factors after mTBI.

Baby boomers' position in the caregiving context is shifting from caregiver to care recipient as the population ages. While the unique characteristics of baby boomer caregivers are well established in caregiving literature, there is limited information about the next caregiving group after the baby boomers. In this study, the sociodemographic and caregiving-related characteristics of the two generations are compared and specific factors contributing to caregiver burden between baby boomer and post baby boomer caregivers are identified. This cross-sectional and correlational study used secondary analysis of data from the National Alliance for Caregiving and the American Association of Retired Persons. A structured online survey was conducted in 2014 with randomly selected samples (n = 1069) in the United States focusing on sociodemographics, caregiving-related characteristics, and burden of care. Descriptive statistics, multivariate linear regression analyses, and Steiger's Z-test were used to identify group differences in multivariate factors related to caregiver burden in two generational groups. Baby boomers and post baby boomers experienced caregiver burden to a similar degree. Caregiving-related factors are more likely to increase burden of care than sociodemographics in both groups. Caregiving without choice and spending longer hours on caregiving tasks were common factors that increased the burden in both generational groups (all p values baby boomer caregivers reported additional challenges, such as unemployment during caregiving, the dual responsibility of both adult and child care, and a family relationship with the care recipient. Due to the aging population of baby boomers, post baby boomers encounter different challenges related to caregiving burden, which is often considered an additional workload in their life course. Current policy and program tailored to baby boomers should be re-designed to meet the different needs of emerging caregivers

However, in Colombia there are no studies about it. Objective: To establish the prevalence of compliance with intravenous chemotherapy on adult oncology patients that started and finished the treatment between January of 2011 and January of 2012 in the Hemato-Oncology service of a general hospital. Specifically, we sought to characterize the sample and recognize the associated factors of noncompliance. Sample: 107 cancer patients that met the inclusion criteria. Method: Study with a quantitative approach, non-experimental, cross exploratory. The statistical analysis was done with the program SPSS making an analysis of the central tendency measures, the frequency distribution, and contingency tables applying the chi-square (X2 test and Fisher’s test. Results: The prevalence of noncompliance of chemotherapy was 68 % and the prevalence of compliance was 32 %. Disease stage was found to be an associated factor. Conclusion: Noncompliance has a high prevalence in the studied sample, indicating the importance of bigger scale studies to gain nation-wide information on the prevalence of the phenomenon, as well as the associated factors, to generate proposals of appropriate interventions to the Colombian population considering the role of psychologists in the development and implementation of these strategies and interventions because it should not be forgotten that compliance is a behavioral issue.

The occurrence of the secondary disasters of forest fire has significant impacts on the environment quality and human health and safety. Post-fire debris flow is one of the most hazardous secondary disasters of forest fire. To understand the occurrence conditions of post-fire debris flow and to master its occurrence situation are the critical elements in post-fire hazard assessment. From the viewpoints of vegetation, precipitation threshold and debris flow material sources, this paper elaborated the impacts of forest fire on the debris flow, analyzed the geologic and geomorphic conditions, precipitation and slope condition that caused the post-fire debris flow as well as the primary mechanisms of debris-flow initiation caused by shallow landslide or surface runoff, and reviewed the research progress in the prediction and forecast of post-fire debris flow and the related control measures. In the future research, four aspects to be focused on were proposed, i. e., the quantification of the relationships between the fire behaviors and environmental factors and the post-fire debris flow, the quantitative research on the post-fire debris flow initiation and movement processes, the mechanistic model of post-fire debris flow, and the rapid and efficient control countermeasures of post-fire debris flow.

To investigate the associated factors and change trajectories of quality of life (QoL), global outcome, and post-concussion symptoms (PCS) over the first year following mild traumatic brain injury (mTBI). This was a prospective longitudinal study of 100 participants with mTBI from neurosurgical outpatient departments in Chiayi County District Hospitals in Taiwan. The checklist of post-concussion syndromes (CPCS) was used to assess PCS at enrollment and at 1, 3, and 12 months after mTBI; the glasgow outcome scale extended (GOSE), the quality of life after brain injured (QOLIBRI), Chinese version, and the Short Form 36 Health Survey (SF-36), Taiwan version, were used to assess mTBI global outcome and QoL at 1, 3, and 12 months after mTBI. Latent class growth models (LCGMs) indicated the change trajectories of QOLIBRI, PCS SF-36, MCS SF-36, GOSE, and PCS. Classes of trajectory were associated with age ≥40 years, unemployment at 1 month after injury, and educational level ≤12 years. Univariate analysis revealed that employment status at 1 month post-injury was correlated with the trajectories of QOLIBRI, PCS SF-36, MCS SF-36, and GOSE, but not PCS. Employment status was the most crucial associated factor for QoL in individuals with mTBI at the 1-year follow-up. Future studies should explore the benefits of employment on QoL of individuals with mTBI.

Introduction The aim of this study was to develop and validate a questionnaire for the assessment of pelvic floor disorders, their symptoms and risk factors in pregnancy and after birth including symptom course, severity and impact on quality of life. Methods The validated German pelvic floor questionnaire was modified and a new risk factor domain developed. The questionnaire was initially completed by 233 nulliparous women in the third trimester of pregnancy and at six weeks (n = 148) and one year (n = 120) post partum. Full pyschometric testing was performed. The clinical course of symptoms and the influence of risk factors were analysed. Results Study participants had a median age of 31 (19-46) years. 63 % had spontaneous vaginal deliveries, 15 % operative vaginal deliveries and 22 % were delivered by caesarean section. Content validity: Missing answers never exceeded 4 %. Construct validity: The questionnaire distinguished significantly between women who reported bothersome symptoms and those who did not. Reliability: Cronbach's alpha values exceeded 0.7 for bladder, bowel and support function, and 0.65 for sexual function. The test-retest analysis showed moderate to almost complete concordance. The intraclass coefficients for domain scores (between 0.732 and 0.818) were in acceptable to optimal range. Reactivity: The questionnaire was able to track changes significantly with good effect size for each domain. Risk factors for pelvic floor symptoms included familial predisposition, maternal age over 35 years, BMI above 25, nicotine abuse, subjective inability to voluntarily contract the pelvic floor musculature and postpartum wound pain. Conclusion This pelvic floor questionnaire proved to be valid, reliable and reactive for the assessment of pelvic floor disorders, their risk factors, incidence and impact on quality of life during pregnancy and post partum. The questionnaire can be utilised to assess the course of symptoms and treatment effects

The role of computer simulation in predicting intrinsic diffusion effects is amplified with the shrinkage of MOS devices. In this work, post-implant damage distributions are obtained from atomistic Monte Carlo (MC) simulations. Based on diffusion-limiting kinetics, the evolution of the damage at room temperature with time is studied. It is shown that evolution of the point defects follow the Ostwald ripening process, where larger defect clusters grow at the expense of smaller ones. A qualitative study of the effective plus factor is also conducted, taking into account various clustering and recombination processes. Clustering is found to significantly affect the remaining amount of damage, which in turn affects subsequent diffusion processes

With the publication of the International Statistical Classification of Diseases and Related Health Problems, 11th edition (ICD-11) due for release in 2018, a number of studies have assessed the factorial validity of the proposed post-traumatic stress disorder (PTSD) and complex (CPTSD) diagnostic criteria and whether the disorders are correlated but distinct constructs. As the specific nature of CPTSD symptoms has yet to be firmly established, this study aimed to examine the dimension of affect dysregulation as two separate constructs representing hyper-activation and hypo-activation. Seven alternative models were estimated within a confirmatory factor analytic framework using the International Trauma Questionnaire (ITQ). Data were analysed from a young adult sample from northern Uganda ( n  = 314), of which 51% were female and aged 18-25 years. Forty per cent of the participants were former child soldiers ( n  = 124) while the remainder were civilians ( n  = 190). The prevalence of CPTSD was 20.8% and PTSD was 13.1%. The results indicated that all models that estimated affective dysregulation as distinct but correlated constructs (i.e. hyper-activation and hypo-activation) provided satisfactory model fit, with statistical superiority for a seven-factor first-order correlated model. Furthermore, individuals who met the criteria for CPTSD reported higher levels of war experiences, symptoms of anxiety and depression, and somatic problems than those with PTSD only and no diagnosis. There was also a much larger proportion of former child soldiers that met the criteria for a CPTSD diagnosis. In conclusion, these results partly support the factorial validity of the ICD-11 proposals for PTSD and CPTSD in a non-Western culture exposed to mass violence. These findings highlight that more research is required across different cultural backgrounds before firm conclusions can be made regarding the factor structure of CPTSD using the ITQ.

Previous studies have suggested that the incidence of post-traumatic stress disorder in earthquake rescue workers is relatively high. Risk factors for this disorder include demographic characteristics, earthquake-related high-risk factors, risk factors in the rescue process, personality, social support and coping style. This study examined the current status of a unit of 1 040 rescue workers who participated in earthquake relief for the Wenchuan earthquake that occurred on May 12(th), 2008. Post-traumatic stress disorder was diagnosed primarily using the Clinician-Administered Post-traumatic Stress Disorder Scale during structured interviews. Univariate and multivariate statistical analyses were used to examine major risk factors that contributed to the incidence of post-traumatic stress disorder. Results revealed that the incidence of this disorder in the rescue group was 5.96%. The impact factors in univariate analysis included death of family members, contact with corpses or witnessing of the deceased or seriously injured, near-death experience, severe injury or mental trauma in the rescue process and working at the epicenter of the earthquake. Correlation analysis suggested that post-traumatic stress disorder was positively correlated with psychotic and neurotic personalities, negative coping and low social support. Impact factors in multivariate logistic regression analysis included near-death experience, severe injury or mental trauma, working in the epicenter of the rescue, neurotic personality, negative coping and low social support, among which low social support had the largest odds ratio of 20.42. Findings showed that the occurrence of post-traumatic stress disorder was the result of the interaction of multiple factors.

Brain-derived neurotrophic factor (BDNF), which regulates neuronal survival, growth differentiation, and synapse formation, is known to be associated with depression and post-traumatic stress disorder (PTSD). However, the molecular mechanism for those mental disorders remains unknown. Studies have shown that BDNF is associated with PTSD risk and exaggerated startle reaction (a major arousal manifestation of PTSD) in United States military service members who were deployed during the wars in Iraq and Afghanistan. The frequency of the Met/Met in BDNF gene was greater among those with PTSD than those without PTSD. Among individuals who experienced fewer lifetime stressful events, the Met carriers have significantly higher total and startle scores on the PTSD Checklist than the Val/Val carriers. In addition, subjects with PTSD showed higher levels of BDNF in their peripheral blood plasma than the non-probable-PTSD controls. Increased BDNF levels and startle response were observed in both blood plasma and brain hippocampus by inescapable tail shock in rats. In this paper, we reviewed these data to discuss BDNF as a potential biomarker for PTSD risk and its possible roles in the onset of PTSD. PMID:27014593

The objective of the study presented here was to perform an empirical investigation on factors affecting healthcare workers acceptance and utilisation of e-learning in post-school healthcare education. E-learning benefits are realised when key features of e-learning are not only applied, but deemed useful, compatible with the learning process and supportive in order to reach the overall goals of the learning process. We conducted a survey of 14 state-enrolled nurses and skilled-workers within the field of healthcare in Norway. The results show that perceived compatibility and subjective norm explain system usage of the e-learning tool amongst the students. We found that the fact that the students considered the e-learning to be compatible with the course in question had a positive effect on e-learning tool usage. We also found support for factors such as facilitating conditions and ease of use leads to the e-learning tool being considered useful.

As further understanding is required of what behavioural factors are associated with long-term weight-loss success, the aim of the present study was to determine the prevalence of successful weight loss 15 months post-enrolment in a commercial web-based weight-loss programme and which behavioural factors were associated with success. An online survey was completed 15 months post-enrolment in a commercial web-based weight-loss programme to assess weight-related behaviours and current weight. Participants were classified as successful if they had lost ≥5 % of their starting weight after 15 months. Commercial users of a web-based weight-loss programme. Participants enrolled in the commercial programme between August 2007 and May 2008. Six hundred and seventy-seven participants completed the survey. The median (interquartile range) weight change was -2·7 (-8·2, 1·6) % of enrolment weight, with 37 % achieving ≥5 % weight loss. Multivariate logistic regression analysis found success was associated with frequency of weight self-monitoring, higher dietary restraint score, lower emotional eating score, not skipping meals, not keeping snack foods in the house and eating takeaway foods less frequently. The findings suggest that individuals trying to achieve or maintain ≥5 % weight loss should be advised to regularly weigh themselves, avoid skipping meals or keeping snack foods in the house, limit the frequency of takeaway food consumption, manage emotional eating and strengthen dietary restraint. Strategies to assist individuals make these changes to behaviour should be incorporated within obesity treatments to improve the likelihood of successful weight loss in the long term.

Post retention and post/core shear bond strength of four post systems.

Stockton, L W; Williams, P T; Clarke, C T

2000-01-01

As clinicians we continue to search for a post system which will give us maximum retention while maximizing resistance to root fracture. The introduction of several new post systems, with claims of high retentive and resistance to root fracture values, require that independent studies be performed to evaluate these claims. This study tested the tensile and shear dislodgment forces of four post designs that were luted into roots 10 mm apical of the CEJ. The Para Post Plus (P1) is a parallel-sided, passive design; the Para Post XT (P2) is a combination active/passive design; the Flexi-Post (F1) and the Flexi-Flange (F2) are active post designs. All systems tested were stainless steel. This study compared the test results of the four post designs for tensile and shear dislodgment. All mounted samples were loaded in tension until failure occurred. The tensile load was applied parallel to the long axis of the root, while the shear load was applied at 450 to the long axis of the root. The Flexi-Post (F1) was significantly different from the other three in the tensile test, however, the Para Post XT (P2) was significantly different to the other three in the shear test and had a better probability for survival in the Kaplan-Meier survival function test. Based on the results of this study, our recommendation is for the Para Post XT (P2).

A prolonged latent phase of the first stage of labour showed a significant association with failed induction of labour. (author)

Post-accession economic development of Poland

Witold ORŁOWSKI

2011-12-01

Full Text Available The aim of this paper is to analyse the economic performance of Poland in the post-accession period. Poland joined the EU in 2004, after a long and difficult economic transition. The whole post-accession period could be divided into two sub-periods: the pre-crisis period of 2004-07, and the turbulent period of 2008-11. During the pre-crisis period, Poland recorded a fast growth, with a built-up of macroeconomic disequilibria. During the turbulent period, the economy was dealing successfully with the global financial crisis. The growth slowed down and the disequilibria were reduced. The paper discusses the growth patterns in the both sub-periods and tries to explain the factors that contributed to the good economic performance during the financial crisis. The astonishingly good economic growth results cannot be attributed to a single factor, but to a combination of many factors contributing at the same time. However, Poland has many valuable assets that may help in dealing with the further economic turbulences.

Post-traumatic syringomyelia

1999-01-01

The improvement of preclinical emergency medicine, better surgical and conservative therapies, and the development of intensive care units and specialized centers have improved the survival rate for patients with serious spinal cord injuries. Therefore, more sequelae of chronic spinal cord injuries such as post-traumatic spinal cord cavitations also occur. The first such case was described by Bastian in 1867. Generally, these cavitations were diagnosed from 2 months up to 32 years after the trauma. The overall prevalence of post-traumatic syringomyelia (PTS) is not known; however, with the increasing use of magnetic resonance imaging (MRI), its diagnosis has increased, ranging from 2.3% of paraplegic and tetraplegic patients in 1976 and 3.2% in 1985, to nearly 50% in a selected group of patients in 1991 and 1993. In 1995, a 4.45% incidence was reported. In our clinic we are currently treating 440 cases of syringomyelia, 140 of which are PTS. Several observations suggest more than one potential mechanism for the evolution of a post-traumatic cyst or PTS. Various factors, such as hemorrhage or, in particular, ischemia within the spinal cord, blockage of the cerebrosinal fluid (CSF) pathways around the cord or localized meningeal fibrosis either alone or in combination with other factors, may be involved. Clinically, sensory disturbances, loss of motor function, pain, and modification of the deep tendon reflexes are observed in most patients. On MRI, PTS is seen as a longitudinal, cystic cavity within the spinal cord, giving a hypointense signal on T 1 -weighted images and a hyperintense signal on T 2 -weighted images. For treatment planning it is mandatory to identify the lower and upper end of the PTS on the MRI. (orig.) [de

En este estudio se utilizaron 14 muestras de Ganoderma y dos de Tomophagus recolectados en Brasil para la extracción de ADN, amplificación y secuenciación de las regiones ITS y LSU. La delimitación filogenética de seis táxones neotropicales fue discutida con base en especímenes brasileños y secuencias del GenBank. Estas especies mostraron ser distintas de los Ganoderma lacados de Asia, Europa, América del Norte y de algunos ejemplares de Argentina. Las reconstrucciones filogenéticas confirman que los Ganoderma lacados son distintos de Tomophagus, aunque pertenecen al mismo grupo. No se confirman los sinónimos de G. subamboinense a G. multiplicatum, de G. boninense a G. orbiforme y G. chalceum a G. cupreum. G. parvulum se confirma como el nombre correcto para G. stipitatum. G. lucidum sólo se debe utilizar para especies europeas. Por lo tanto, se propone el uso de nombres publicados válidamente de acuerdo con la distribución geográfica de las muestras, características morfológicas y análisis de ADNr.

This cross-sectional correlational study examined post-partum depression and its relationship with demographic, maternal, and infant health problems in urban Jordanian women. Participants (n = 315) were selected from five maternal child healthcare centers and one major hospital in Amman, Jordan. Patient Health Questionnaire-9 was used to measure post-partum depression within 12 weeks of birth. A number of socio-demographic and health problems were examined for an association with post-partum depression. Results showed that 25% of post-partum women suffered moderate to severe depression and 50% of the sample had mild depression. None of the socio-demographic variables (age, education, employment, income) were significantly related to post-partum depression; however, two obstetric/infant variables (mode of birth and breastfeeding), were significantly associated with post-partum depression. There was a significant association between post-partum depression and 15 health problems of obstetric, gynecologic (i.e. episiotomy pain, infection), and general health conditions (i.e. fatigue, headache). Nurses and midwives need to emphasize post-partum depression screening, follow-up, and proper management of maternal and infant health factors predisposing to post-partum depression rather than merely focusing on women's inherent demographic factors. © 2015 Wiley Publishing Asia Pty Ltd.

Among organ transplant recipients, the African American population historically has received special attention. This is because secondary to their disposition to certain disease states, for example hypertension, an African American patient has a propensity to reach end-stage renal disease and require renal replacement earlier than a Caucasian patient. Regardless of the initiative to replace dialysis therapy with organ transplantation, the African American patient has many barriers to kidney transplantation, thus extending their time on dialysis and waiting time on the organ transplant list. These factors are among the many negative causes of decreased kidney graft survival, realized before kidney transplantation. Unfortunately, once the African American recipient receives a kidney graft, the literature documents that many post-transplant barriers exist which limit successful outcomes. The primary post-transplant barrier relates to designing proper immunosuppression protocols. The difficulty in designing protocols revolves around (i) altered genetic metabolism/lower absorption, (ii) increased immuno-active cytokines and (iii) detrimental effects of noncompliance. Based on the literature, dosing of immunosuppression must be aggressive and requires a diligent practitioner. Research has indicated that, despite some success with proven levels of immunosuppression, the African American recipient usually requires a higher 'dose per weight' regimen. However, even with aggressive immunosuppressant dosing, African Americans still have worse outcomes than Caucasian recipients. Additionally, many of the targeted sites of action that immunosuppression exerts its effects on have been found to be amplified in the African American population. Finally, noncompliance is the most discouraging inhibitor of long-term success in organ transplantation. The consequences of noncompliance are biased by ethnicity and affect the African American population more severely. All of these factors

Identify the environmental factors that influence stroke-survivors' reengagement in personally valued activities and determine what specific environmental factors are related to specific valued activity types. PubMed, CINAHL and PsycINFO were searched until June 2016 using multiple search-terms for stroke, activities, disability, and home and community environments. An integrated mixed-method systematic review of qualitative, quantitative and mixed-design studies was conducted. Two researchers independently identified relevant studies, assessed their methodological quality and extracted relevant findings. To validly compare and combine the various findings, all findings were classified and grouped by environmental category and level of evidence. The search yielded 4024 records; 69 studies were included. Most findings came from low-evidence-level studies such as single qualitative studies. All findings were consistent in that the following factors facilitated reengagement post-stroke: personal adapted equipment; accessible environments; transport; services; education and information. Barriers were: others' negative attitudes and behaviour; long distances and inconvenient environmental conditions (such as bad weather). Each type of valued activity, such as mobility or work, had its own pattern of environmental influences, social support was a facilitator to all types of activities. Although in many qualitative studies others' attitudes, behaviour and stroke-related knowledge were seen as important for reengagement, these factors were hardly studied quantitatively. A diversity of environmental factors was related to stroke-survivors' reengagement. Most findings came from low-evidence-level studies so that evidence on causal relationships was scarce. In future, more higher-level-evidence studies, for example on the attitudes of significant others, should be conducted.

Post-partum depression, although heterogeneous, is often considered a medical disease when viewed from the biomedical perspective. However, recent reports from the Indian subcontinent have documented psychosocial causal factors. This study employed qualitative methodology in a representative sample of women in rural South India. Women in the post-partum period were assessed using the Tamil versions of the Short Explanatory Model Interview, the Edinburgh Postnatal Depression Scale and a semi-structured interview to diagnose ICD 10 depression. Socio-demographic and clinical details were also recorded. Some 137 women were recruited and assessed, of these, 26.3% were diagnosed to have post-partum depression. The following factors were associated with post-partum depression after adjusting for age and education: age less than 20 or over 30 years, schooling less than five years, thoughts of aborting current pregnancy, unhappy marriage, physical abuse during current pregnancy and after childbirth, husband's use of alcohol, girl child delivered in the absence of living boys and a preference for a boy, low birth weight, and a family history of depression. Post-partum depression was also associated with an increased number of causal models of illness, a number of non-medical models, treatment models and non-medical treatment models. Many social and cultural factors have a major impact on post-partum depression. Post-partum depression, when viewed from a biomedical framework, fails to acknowledge the role of context in the production of emotional distress in the post-partum period.

We conducted a prospective study on 81 consecutive patients who had a kidney transplant with graft function for over 3 months to evaluate the prevalence of erythrocytosis following renal transplantation (PTE) and its potential risk factors. True PTE was defined as a RBC mass > 120% of the theoretical value allowing for sex, weight and height. 18 patients (22.2%) developed PTE (RBC mass = 157 +/- 21%) with no evidence of polycythemia vera (PV), or secondary polycythemia due to reduced arterial oxygen, kidney or hepatic tumors. PTE was more common in males (p = 0.041) and less common in patients treated with recombinant erythropoietin (rHEPO) prior to transplantation. 18 non-polycythemic patients (Hb 12.6 +/- 1.3 g/dl) matched for sex, age and renal function were used as case controls. Fewer PTE patients were transfused post-transplantation (p = 0.026). At the time of diagnosis, mean serum EPO was normal and similar to that of controls. PTE patients had lower serum ferritin (p = 0.005) and more commonly received iron supplementation when PTE occurred (p = 0.003). Other clinical factors did not differ significantly between the two groups. Two patients had a thrombotic event, 6 recovered spontaneously and 11 were successfully treated with angiotensin-converting enzyme inhibitors (ACEI). The normalization of Hb, hematocrit and RBC mass in ACEI treated patients was accompanied by a decline in serum EPO (p = 0.008). We conclude that true erythrocytosis is prevalent in cyclosporine-treated renal transplant patients. PTE seems to be an idiopathic erythrocytosis. Pretransplant rHEPO treatment may limit PTE by blunting the increased sensitivity of erythroid precursors to EPO and iron supplementation, which stimulates the development of PTE. ACEI treatment is effective and safe.

Objective To obtain information on the socioeconomic, medical, and functional status of polio survivors, and to use these results as the preliminary data for establishing the middle-aged cohort of polio survivors. Methods The subjects were recruited based on the medical records of multiple hospitals and centers. They were assessed through a structured questionnaire over the phone. Post-poliomyelitis syndrome (PPS) was identified according to the specified diagnostic criteria. Differences between polio survivors with or without PPS were evaluated, and the risk factors for PPS were analyzed by the odds ratio (OR). Results Majority of polio survivors were middle-aged and mean age was 51.2±8.3 years. A total of 188 out of 313 polio survivors met the adopted criteria for PPS based on the symptoms, yielding a prevalence of 61.6%. Mean interval between acute poliomyelitis and the development of PPS was 38.5±11.6 years. Female gender (OR 1.82; confidence interval [CI] 1.09-3.06), the age at onset of poliomyelitis (OR 1.75; CI 1.05-2.94), the use of orthoses or walking aids (OR 2.46; CI 1.44-4.20), and the history of medical treatment for paralysis, pain or gait disturbance (OR 2.62; CI 1.52-4.51) represented independent risk factors for PPS. Conclusion We found that the majority of Korean polio survivors entered middle age with many medical, functional, and social problems. Female gender, early age of onset of poliomyelitis, the use of orthoses or walking aids, and the history of medical treatment for paralysis, pain or gait disturbance were identified as the significant risk factors for PPS. A comprehensive and multidisciplinary plan should be prepared to manage polio survivors considering their need for health care services and the risk factors for late effects, such as PPS.

Prevalence and risk factors of PTSD among injured garment workers who survived a major factory collapse. Survivors receiving treatment or rehabilitation care at one year post event were surveyed, which included Post Traumatic Stress Disorder Checklist Specific version. The respondents consisted of 181 people with a mean age of 27.8 years and a majority had less than high school education (91.2%). Multivariable logistic regression found that the odds of having PTSD was higher among married (OR: 3.2 [95% CI: 1.3-8.0]), those who used to work more than 70 hr/week (OR: 2.4 [1.1-5.3]), workers who used to hold higher job positions (OR: 2.6 [1.2-5.6]) or who had a concussion injury (OR: 3.7 [1.4-9.8]). Among the respondents, 83.4% remained unemployed, and only 57.3% (63 people) reported receiving a quarter or less of what they were promised as compensation.

Despite increased use of the Alcohol Use Disorders Identification Test (AUDIT) in sub-Saharan Africa, few studies have assessed its underlying conceptual framework, and none have done so in post-conflict settings. Further, significant inconsistencies exist between definitions used for problematic consumption. Such is the case in Uganda, facing one of the highest per-capita alcohol consumption levels regionally, which is thought to be hindering rebuilding in the North after two decades of civil war. This study explores the impact of varying designation cutoff thresholds in the AUDIT as well as its conceptual factor structure in a representative sample of the population. In all, 1720 Cango Lyec Project participants completed socio-economic and mental health questionnaires, provided blood samples and took the AUDIT. Participant characteristics and consumption designations were compared at AUDIT summary score thresholds of ≥3, ≥5 and ≥8. Confirmatory factor analyses (CFA) explored one-, two- and three-factor level models overall and by sex with relative and absolute fit indicators. There were no significant differences in participant demographic characteristics between thresholds. At higher cutoffs, the test increased in specificity to identify those with hazardous drinking, disordered drinking and suffering from alcohol-related harms. All conceptual models indicated good fit, with three-factor models superior overall and within both sexes. In Northern Uganda, a three-factor AUDIT model best explores alcohol use in the population and is appropriate for use in both sexes. Lower cutoff thresholds are recommended to identify those with potentially disordered drinking to best plan effective interventions and treatments. A CFA of the AUDIT showed good fit for one-, two, and three-factor models overall and by sex in a representative sample in post-conflict Northern Uganda. A three-plus total AUDIT cutoff score is suggested to screen for hazardous drinking in this or

Objective We examine the role of family- and individual-level protective factors in the relation between exposure to ethnic-political conflict and violence and post-traumatic stress among Israeli and Palestinian youth. Specifically, we examine whether parental mental health (lack of depression), positive parenting, children’s self-esteem, and academic achievement, moderate the relation between exposure to ethnic-political conflict/violence and subsequent post-traumatic stress (PTS) symptoms. Method We collected three waves of data from 901 Israeli and 600 Palestinian youths (three age cohorts: 8, 11, and 14 years old; approximately half of each gender) and their parents at 1-year intervals. Results Greater cumulative exposure to ethnic-political conflict/violence across the first two waves of the study predicted higher subsequent PTS symptoms even when we controlled for the child’s initial level of PTS symptoms. This relation was significantly moderated by a youth’s self-esteem and by the positive parenting received by the youth. In particular, the longitudinal relation between exposure to violence and subsequent PTS symptoms was significant for low self-esteem youth and for youth receiving little positive parenting but was non-significant for children with high levels of these protective resources. Conclusions Our findings show that youth most vulnerable to PTS symptoms as a result of exposure to ethnic-political violence are those with lower levels of self-esteem and who experience low levels of positive parenting. Interventions for war-exposed youth should test whether boosting self-esteem and positive parenting might reduce subsequent levels of PTS symptoms. PMID:22594697

This prospective longitudinal study compared pretraumatic, peritraumatic, and post-traumatic predictors of post-traumatic growth (PTG) and post-traumatic stress disorder (PTSD). A total of 103 Israeli former prisoners of the Yom Kippur War were followed over 30 years. Sociodemographic variables, trauma exposure, reactions in captivity, world assumptions, social support, and personality factors were assessed in 1991, and PTG and PTSD symptoms in 2003. Hierarchical regression modeling showed that although some predictors, namely, loss of control and active coping during captivity, predicted both PTG and PTSD, others predicted one outcome and not the other. Self-controllability predicted PTG while sociodemographic factors predicted PTSD when controlling for PTSD and PTG, respectively. The findings indicate that salutary and pathogenic trauma outcomes share some but not all precursors, underscoring their multifaceted relationship. © 2010 Wiley Periodicals, Inc.

The neurogenic factor NeuroD1 is expressed in post-mitotic cells during juvenile and adult Xenopus neurogenesis and not in progenitor or radial glial cells.

Full Text Available In contrast to mammals that have limited proliferation and neurogenesis capacities, the Xenopus frog exhibit a great potential regarding proliferation and production of new cells in the adult brain. This ability makes Xenopus a useful model for understanding the molecular programs required for adult neurogenesis. Transcriptional factors that control adult neurogenesis in vertebrate species undergoing widespread neurogenesis are unknown. NeuroD1 is a member of the family of proneural genes, which function during embryonic neurogenesis as a potent neuronal differentiation factor. Here, we study in detail the expression of NeuroD1 gene in the juvenile and adult Xenopus brains by in situ hybridization combined with immunodetections for proliferation markers (PCNA, BrdU or in situ hybridizations for cell type markers (Vimentin, Sox2. We found NeuroD1 gene activity in many brain regions, including olfactory bulbs, pallial regions of cerebral hemispheres, preoptic area, habenula, hypothalamus, cerebellum and medulla oblongata. We also demonstrated by double staining NeuroD1/BrdU experiments, after long post-BrdU administration survival times, that NeuroD1 gene activity was turned on in new born neurons during post-metamorphic neurogenesis. Importantly, we provided evidence that NeuroD1-expressing cells at this brain developmental stage were post-mitotic (PCNA- cells and not radial glial (Vimentin+ or progenitors (Sox2+ cells.

Addressing air leakage of dwellings is important to improving energy efficiency and thermal comfort. This paper reports on the air permeability test results of 287 post-2006 new-build dwellings in the UK. The paper explores the relationships between air-tightness and its influencing factors including build method, dwelling type, management context, design target, season, number of significant penetrations, and envelope and floor area. One-way ANOVA analysis was utilised to compare means of air permeability in relation to the individual factors, and two- and three-way ANOVA analyses were applied for examining the interactions between them. The air-tightness of the dwellings averaged 5.97 m{sup 3}/(h m{sup 2}) at 50 Pa, which has improved from UK historic data. Dwellings built using precast concrete panels were significantly air-tighter than those built using timber frame, whilst those masonry and reinforced concrete frame dwellings were most leaky. Greater extent of innovative practice and 'self-build' procurement led to achieving superior air-tightness. Interaction was observed between 'build method' and 'dwelling type' and between 'dwelling type' and 'management context'. A modest positive correlation was noticed between air permeability and design target, which became weak in relation to the number of significant penetrations and envelope area. Applying the linear regression technique a predictive model is developed for estimating air permeability of dwellings. This model integrates the influencing factors and their significant interactions. The findings should contribute to future research in predicting impacts of controlling the influencing factors on achieving air-tightness of dwellings more consistently. (author)

While induced abortion is considered to be illegal and socially unacceptable in Nigeria, it is still practiced by many women in the country. Poor family planning and unsafe abortion practices have daunting effects on maternal health. For instance, Nigeria is on the verge of not meeting the Millennium development goals on maternal health due to high maternal mortality ratio, estimated to be about 630 maternal deaths per 100,000 live births. Recent evidences have shown that a major factor in this trend is the high incidence of abortion in the country. The objective of this paper is, therefore, to investigate the factors determining the demand for abortion and post-abortion care in Ibadan city of Nigeria. The study employed data from a hospital-based/exploratory survey carried out between March to September 2010. Closed ended questionnaires were administered to a sample of 384 women of reproductive age from three hospitals within the Ibadan metropolis in South West Nigeria. However, only 308 valid responses were received and analysed. A probit model was fitted to determine the socioeconomic factors that influence demand for abortion and post-abortion care. The results showed that 62% of respondents demanded for abortion while 52.3% of those that demanded for abortion received post-abortion care. The findings again showed that income was a significant determinant of abortion and post-abortion care demand. Women with higher income were more likely to demand abortion and post-abortion care. Married women were found to be less likely to demand for abortion and post-abortion care. Older women were significantly less likely to demand for abortion and post-abortion care. Mothers' education was only statistically significant in determining abortion demand but not post-abortion care demand. The findings suggest that while abortion is illegal in Nigeria, some women in the Ibadan city do abort unwanted pregnancies. The consequence of this in the absence of proper post

Married women were found to be less likely to demand for abortion and post-abortion care. Older women were significantly less likely to demand for abortion and post-abortion care. Mothers’ education was only statistically significant in determining abortion demand but not post-abortion care demand. Conclusion The findings suggest that while abortion is illegal in Nigeria, some women in the Ibadan city do abort unwanted pregnancies. The consequence of this

This transversal study was carried out with a multiprofessional team in the pre-hospital care in Minas Gerais, Brazil. It aimed to estimate the incidence of occupational accidents by exposure to biological material and post-accidents conductsta. Descriptive analysis and logistic regression were used. Incidence of accidents was 19.8%: 39,1% perforating-cutting materials and 56.5% body fluids. Doctors (33.3%) and drivers (24.0%) were most involved. Inadequate subsequent measures were highly prevalent: no medical assessment (69.6%), no work accident communication issued (91.3%), no measures (52.2%) and no serological follow-up (52.2%). Variables associated with accidents were: age >31 years old (OR = 3,02; IC95%: 1,25 - 7,33; p = 0,014) and working in basic support units (OR = 5,36; IC95%: 1,51 19,08; p = 0,010). The implementation of post-accidents protocols is suggested in order to reduce accidents and under-notification, and increase post-accident follow-up.

Refugees demonstrate high rates of post-traumatic stress disorder (PTSD) and other psychological disorders. The recent increase in forcible displacement internationally necessitates the understanding of factors associated with refugee mental health. While pre-migration trauma is recognized as a key predictor of mental health outcomes in refugees and asylum seekers, research has increasingly focused on the psychological effects of post-migration stressors in the settlement environment. This article reviews the research evidence linking post-migration factors and mental health outcomes in refugees and asylum seekers. Findings indicate that socioeconomic, social, and interpersonal factors, as well as factors relating to the asylum process and immigration policy affect the psychological functioning of refugees. Limitations of the existing literature and future directions for research are discussed, along with implications for treatment and policy.

To determine the incidence and severity of post-traumatic growth in a group of parents of children hospitalised in the intensive care unit in the past. A premature birth or a birth with life-threatening conditions is a traumatic event for the parents and may lead to a number of changes, some of which are positive, known as post-traumatic growth. The survey covered 106 parents of 67 infants aged 3-12 months. An original questionnaire and standardised research tools were used in the study: Impact Event Scale - Revised, Perceived Stress Scale, COPE Inventory: Positive Reinterpretation and Growth, Coping Inventory for Stressful Situations, Post-traumatic Growth Inventory and Parent and Infant Characteristic Questionnaire. Due to a stepwise backward variables selection, we found three main factors that explain post-traumatic growth: post-traumatic stress symptoms, positive reinterpretation and growth and dichotomic variable infants' survival. This model explained 29% of the post-traumatic growth variation. Similar models that were considered separately for mothers and fathers showed no significantly better properties. Post-traumatic growth was related to a lesser extent to sociodemographic variables or the stressor itself, and related to a far greater extent to psychological factors. Our study highlights the fact that post-traumatic growth in the parents of neonates hospitalised in the neonatal intensive care units remains under-evaluated. © 2016 John Wiley & Sons Ltd.

Background and study aims  Colorectal cancer (CRC) is one of the most common neoplasms and endoscopic submucosal dissection (ESD) is an effective treatment for early-stage CRC. However, it has been observed that patients undergoing ESD often complain of pain, even if ESD has been successfully performed. Risk factors for such pain still remain unknown. The aim of this study was to explore the risk factors for post-colorectal ESD coagulation syndrome (PECS). Patients and methods  This was a prospective multicenter observational trial (UMIN000016781) conducted in 106 of 223 patients who underwent ESD between March 2015 and April 2016. We investigated age, sex, tumor location, ESD operation time, lesion size, duration of hospitalization, and frequency of PECS. We defined PECS as local abdominal pain (evaluated on a visual analogue scale) in the region corresponding to the site of the ESD that occurred within 4 days of the procedure. Results  PECS occurred in 15/106 (14.2 %), and 10 were women ( P  = 0.01, OR: 7.74 [1.6 – 36.4]), 7 had lesions in the cecum ( P   90 min ( P  = 0.002, OR: 10.3 [2.4 – 44.6]). Frequency of deviation from the prescribed clinical path was significantly higher (47 % [7/15] vs. 2 % [2/91], P  PECS group.  Conclusions  Female gender, location of lesion in the cecum, and ESD operation time > 90 minutes were significant risk factors independent of PECS. These findings are important to management of PECS.  PMID:29527556

The prevalence of post-thrombotic syndrome (PTS) in Spain is not known accurately at present. The main objective of this study was to determine the prevalence of PTS and the possible prognostic factors related to its development and impact on quality of life. This was an observational, multicenter, cross-sectional and retrospective study of patients who had suffered a deep vein thrombosis (DVT) between March 2010 and March 2011. The Villalta scale was applied as a standardized assessment of PTS at the enrollment visit. According to the score, distribution was: patients with PTS (score>4) and patients without PTS (score ≤4). Subsequently, DVT data and risk factors were collected retrospectively. The quality of life of patients was evaluated. In total 511 patients with DVT were enrolled, of which 7 patients were excluded as they did not meet the inclusion/exclusion criteria. The prevalence of PTS was 53%, with 56.2% having a mild character, 20.6% moderate, and 23.2% severe. The presence of risk factors for DVT including immobilization, hormonal therapy and obesity was significantly higher in patients with PTS than in patients without PTS. There were not significant differences in the location of the DVT. The perception of patients about their health was significantly worse in patients with DVT. The prevalence of PTS in patients with DVT is very high. The presence of risk factors for DVT clearly contributes to a greater predisposition to suffering PTS in an average time of 2 years.

Vislovukh A. A.

2013-01-01

Full Text Available Eukaryotic translation elongation factor 1A exists as two 98 % homologous isoforms: eEF1A1 (A1 and eEF1A2 (A2 which are tissue and development specific. Despite high homology in an open reading frame (ORF region, mRNAs coding for eEF1A1 and eEF1A2 are different in their untranslated regions (UTR, suggesting a possibility of their dissimilar post-transcriptional regulation. Aim. To analyze the existence of cis-acting motifs in the UTRs of EEF1A1/A2 mRNAs, to confirm the possibility of post-transcriptional control of eEF1A1 and eEF1A2 expression. Methods. An ensemble of bioinformatic methods was applied to predict regulatory motifs in the UTRs of EEF1A1/A2 mRNAs. Dual-luciferase reporter assay was employed to detect post-transcriptional regulation of eEF1A1/A2 expression. Results. Numerous regulatory motifs in the UTR of EEF1A1/A2 mRNAs were found bioinformatically. The experimental evidence was obtained for the existence of negative regulation of EEF1A1 and positive regulation of EEF1A2 mRNA in the model of breast cancer development. Conclusions. EEF1A1 and EEF1A2 mRNAs contain distinct motifs in the UTRs and are differently regulated in cancer suggesting the possibility of their control by different cellular signals.

Post-traumatic stress disorder and cardiovascular disease.

Edmondson, Donald; von Känel, Roland

2017-04-01

In this paper, a first in a Series of two, we look at the evidence for an association of post-traumatic stress disorder with incident cardiovascular disease risk and the mechanisms that might cause this association, as well as the prevalence of post-traumatic stress disorder due to cardiovascular disease events and its associated prognostic risk. We discuss research done after the publication of previous relevant systematic reviews, and survey currently funded research from the two most active funders in the field: the National Institutes of Health and the US Veterans Administration. We conclude that post-traumatic stress disorder is a risk factor for incident cardiovascular disease, and a common psychiatric consequence of cardiovascular disease events that might worsen the prognosis of the cardiovascular disease. There are many candidate mechanisms for the link between post-traumatic stress disorder and cardiovascular disease, and several ongoing studies could soon point to the most important behavioural and physiological mechanisms to target in early phase intervention development. Similarly, targets are emerging for individual and environmental interventions that might offset the risk of post-traumatic stress disorder after cardiovascular disease events.

Full Text Available Background and Aims: Aging population is a major demographic trend worldwide. Globally, 50% of all the elderly individuals are estimated to undergo atleast one surgical procedure and post-operative cognitive dysfunction (POCD is one of the most common and often poorly understood post-operative complications in this section of the population. This randomised prospective study was conducted to assess the post-operative cognitive status in the elderly undergoing non-cardiac surgery, evaluate the cognitive parameters affected, evaluate the potential risk factors and thereby analyse the potential for implementation of preventive strategies. Methods: This study was conducted on 200 patients aged 60 years or older scheduled for elective non-cardiac surgeries. The baseline cognitive status of the patients was assessed 2 days prior to the date of the surgery. The post-operative cognitive status was assessed on the 3 rd day, 7 th day and after 1 month. Statistical analysis was performed using SAS and SPSS. Results: The incidence of POCD showed a gradual decline from postoperative day 3 to 30. Females were found to be at significant risk in developing POCD. Advancing age and level of education emerged as dominant factors, while type of anaesthesia, duration of surgery, and presence of coexisting comorbidities had no influence on the incidence of cognitive dysfunction. Conclusion: POCD is a definite complication after surgery and anaesthesia in the elderly population. Gender emerged as a significant risk factor with increasing age as a dominating factor contributing to POCD.

Full Text Available Abstract Background There is a relative lack of recent information about late post kidney transplantation anaemia (PTA, especially in the developing countries; data are scarce about the prevalence and risk factors of PTA. Sudan was a leading country in Africa and Arab world in kidney transplantation. The first kidney transplantation in Sudan was in 1973. Methods This is a cross-sectional hospital analytic study enrolling all kidney transplanted recipients following in the transplant referral clinics at Ahmed Gassim, Selma and Ibn Sina Hospitals, Khartoum/Sudan, in the period from 1/8/2010 to 1/9/2010, clinical and laboratory data were obtained from 114 patients, anaemia was defined as Hb levels of Results The study showed that 39.5% of the patients were anaemic. Univariate analysis showed that late PTA is significantly associated with not using Erythropoietin (EPO in the pre-transplant period (p = Conclusion The study concluded that late PTA is common and under recognized. Risk factors for late PTA include renal dysfunction, history of rejection, longer duration of transplantation and not using EPO in the pre-transplant period. Renal dysfunction and not using EPO in the pre-transplant period are major predictors of late PTA.

Age-related changes in factor VII proteolysis in vivo.

Previous studies have reported that pre-operative plasmas of patients over the age of 40 years who developed post-operative deep vein thrombosis (DVT) had approximately twice the amount of proteolysed factor VII found in plasmas of patients in whom prophylaxis with heparin or low M(r) heparin was successful. These and other studies also reported higher concentrations of thrombin-antithrombin III in pre- and post-operative plasmas of patients who developed post-operative thrombosis than in plasmas of patients in whom prophylaxis was successful. Whether the extent of factor VII proteolysis seen in the patients who developed post-operative DVT is related to the severity of their disease or age is not known. This report investigated age-related changes in the concentrations of total factor VII protein, factor VII zymogen, factor VIIa, tissue factor pathway inhibitor, thrombin-antithrombin III, and prothrombin fragment 1 + 2 in normal plasmas and the relationships between these parameters. With the exception of thrombin-antithrombin III, statistically significant increases in the concentrations of these parameters with age were found. Additionally, the differences between the concentrations of total factor VII protein and factor VII zymogen, an index factor VII proteolysis in vivo, were statistically significant only for individuals over age 40. Using linear regression analysis, a significant correlation was found to exist between the concentrations of plasma factor VIIa and prothrombin fragment 1 + 2. Since factor VIIa-tissue factor probably initiates coagulation in vivo, we hypothesize that the elevated plasma factor VIIa (reflecting a less tightly regulated tissue factor activity and therefore increased thrombin production in vivo) accounts for the high risk for post-operative thrombosis seen in individuals over the age of 40.

It remains unclear whether feelings of being disabled are a relevant psychological factor that determines long term outcome after percutaneous coronary intervention (PCI). Therefore, we evaluated 'feelings of being disabled' as an independent risk factor for mortality 12years post-PCI. The study population comprised a consecutive series of CAD patients (n=845) treated with PCI as part of the Taxus-Stent Evaluated At Rotterdam Cardiology Hospital (T-SEARCH) registry. Of these patients n=646 (age 63years, 75% male) completed the subscale 'feelings of being disabled' of the Heart Patients Psychological Questionnaire (HPPQ), within the first month after PCI. At 12year follow-up, n=209 patients (32%) died. Of the 162 females n=73 (45%) experienced high feelings of being disabled (High-FOBD) and of the 484 males, n=134 (28%) reported high-FOBD. Patients with high feelings of being disabled had a two-fold increased risk of mortality at 12-year follow-up (HR=1.86, 95% CI=1.41-2.45). After adjusting, high feelings of being disabled remained a predictor of 12-year mortality (HR=2.53, 95% CI=1.30-4.90). This study confirms that psychosocial variables like feelings of being disabled influence cardiac morbidity and mortality. Furthermore, there is no difference in mortality between men and women with high feelings of being disabled 12years post-PCI. It is important that clinicians are aware that PCI-patients who feel disabled have a less favorable survival and that the difference in survival is even greater for women who feel disabled.

Whiplash injuries are among the leading injuries related to car crashes and it is important to determine the prognostic factors that predict the outcome of patients with these injuries. This meta-review aims to identify factors that are associated with outcome after acute whiplash injury. A systematic search for all systematic reviews on outcome prediction of acute whiplash injury was conducted across several electronic databases. The search was limited to publications in English, and there were no geographical or time of publication restrictions. Quality appraisal was conducted with A Measurement Tool to Assess Systematic Reviews. The initial search yielded 207 abstracts; of these, 195 were subsequently excluded by topic or method. Twelve systematic reviews with moderate quality were subsequently included in the analysis. Post-injury pain and disability, whiplash grades, cold hyperalgesia, post-injury anxiety, catastrophizing, compensation and legal factors, and early healthcare use were associated with continuation of pain and disability in patients with whiplash injury. Post-injury magnetic resonance imaging or radiographic findings, motor dysfunctions, or factors related to the collision were not associated with continuation of pain and disability in patients with whiplash injury. Evidence on demographic and three psychological factors and prior pain was conflicting, and there is a shortage of evidence related to the significance of genetic factors. This meta-review suggests an association between initial pain and anxiety and the outcome of acute whiplash injury, and less evidence for an association with physical factors. Level 1.

Un modelo fenológico permite predecir  el tiempo en que ocurrirá un evento en el desarrollo de un organismo, y el calor acumulado en este proceso se conoce como tiempo fisiológico o grados-día de crecimiento.  El estudio fue realizado en una finca de producción de flores, ubicada en el municipio de Suesca (Cundinamarca, con el objetivo de evaluar el comportamiento fenológico de las variedades de rosas ‘Madame Delbard’, ‘Charlotte’ y ‘Freedom’, como respuesta a la acumulación de grados-día. Para esto, a los estadios fenológicos denominados ‘arroz’, ‘garbanzo’, ‘mostrando color’ y ‘cosecha’ se les hizo un seguimiento desde el momento de la poda. Para la primera cosecha de la variedad ‘Madame Delbard’, se obtuvo una acumulación total de 1085,3 grados-día y el pico de cosecha se presentó a los 86 d y 904,4 grados-día. La variedad ‘Charlotte’ tuvo sus primeras flores a los 49 d, finalizando la cosecha a los 87 d y con 906,3 grados- día. El pico de cosecha se dio a los 69 d y 718,5 grados-día. En el caso de la variedad ‘Freedom’, se necesitaron 50 d después de poda para cortar las primeras flores, a los 80 d y 779,9 grados-día se acentúo la cosecha, finalizando a los 93 d y 892,9 grados-día. Las curvas de producción obtenidas de las tres variedades presentaron un modelo cuadrático, definido por el modelo de regresión de Poisson, excepto para la curva de la ‘Freedom’, que se comportó como un modelo lineal.

To review the incidence of UTIs, post-operative fever, and risk factors for post-operative fever in PCNL patients. Between 2007 and 2009, consecutive PCNL patients were enrolled from 96 centers participating in the PCNL Global Study. Only data from patients with pre-operative urine samples and who received antibiotic prophylaxis were included. Pre-operative bladder urine culture and post-operative fever (>38.5°C) were assessed. Relationship between various patient and operative factors and occurrence of post-operative fever was assessed using logistic regression analyses. Eight hundred and sixty-five (16.2%) patients had a positive urine culture; Escherichia coli was the most common micro-organism found in urine of the 350 patients (6.5%). Of the patients with negative pre-operative urine cultures, 8.8% developed a fever post-PCNL, in contrast to 18.2% of patients with positive urine cultures. Fever developed more often among the patients whose urine cultures consisted of Gram-negative micro-organisms (19.4-23.8%) versus those with Gram-positive micro-organisms (9.7-14.5%). Multivariate analysis indicated that a positive urine culture (odds ratio [OR] = 2.12, CI [1.69-2.65]), staghorn calculus (OR = 1.59, CI [1.28-1.96]), pre-operative nephrostomy (OR = 1.61, CI [1.19-2.17]), lower patient age (OR for each year of 0.99, CI [0.99-1.00]), and diabetes (OR = 1.38, CI [1.05-1.81]) all increased the risk of post-operative fever. Limitations include the use of fever as a predictor of systemic infection. Approximately 10% of PCNL-treated patients developed fever in the post-operative period despite receiving antibiotic prophylaxis. Risk of post-operative fever increased in the presence of a positive urine bacterial culture, diabetes, staghorn calculi, and a pre-operative nephrostomy.

To determine which factors relate to the development of post-traumatic stress disorder, in adult patients who are admitted to critical care units. Patient survival rates from critical care areas are improving each year and this has led to interest in the long-term outcomes for patients who have been discharged from such environments. Patients typically require invasive and extensive treatment, which places a stress on physical and mental health. Prevalence estimates of post-traumatic stress disorder in the critical care discharge population vary from 5-63%, yet it remains unclear what the predisposing factors are. A systematised review. Subject heading and keyword searches were conducted in MEDLINE, CINAHL, PsycINFO and ScienceDirect, with 23 articles identified that examined the relationship between critical care and the development of post-traumatic stress disorder. Three main themes were identified; Critical Care Factors, Patient Factors and Experience Factors. Eight key and three potential causative factors were found: younger age, female, previous psychiatric history, length of ICU stay, benzodiazepine sedation, use of stress hormones, delusional memory and traumatic memory, delirium, GCS score of ≤9 on admission & use of mechanical restraint. Post-traumatic stress reactions can be strongly related to the development and presence of traumatic and delusional memories. Younger patients may exclude themselves from research to avoid their traumatic thoughts. The role of prior psychiatric illness is unknown. Distinction between 'factual' and 'false' or delusional memory as occurs in the literature maybe unhelpful in understanding trauma reactions. There are around 38,000 occupied critical care beds each year in England. The scale of the issue is therefore substantial. Risk factors can be isolated from available evidence and provide a rudimentary risk assessment tool to inform practice development in this area. © 2016 John Wiley & Sons Ltd.

Breast cancer (BC) is potentially a traumatic stressor which may be associated with negative outcomes, such as post-traumatic stress disorder (PTSD) or positive changes, such as post-traumatic growth (PTG). This study aims to identify the core issues of BC related PTSD, PTG and psychological distress by interrogating the literature in BC survivors. We have also highlighted issues related to the assessment, diagnosis and clinical management of PTSD and PTG. The authors systematically reviewed studies published from 1985 to 2014 pertaining to PTSD, psychological distress and PTG in BC survivors with particular attention paid to incidence rates and causative factors. Multiple studies intimated that women with BC have evidence of PTSD at the initial stages of diagnosis, whereas PTG develops once patients undergo treatment. Early diagnosis and treatment of PTSD/PTG is paramount from literature review but the previously mentioned relationship between PTSD and PTG in BC patients could not be verified. It is evident from the literature that a small percentage of BC patients experience PTSD, while the majority experience PTG after BC diagnosis and treatment. Future research should include prospective studies focusing on high-risk patients, causative factors and the development of psychological interventions.

1. To determine the prevalence of left vocal cord paralysis (LVCP) post patent ductus arteriosus (PDA) ligation at a Tertiary Care Centre. 2. To identify risk factors associated with LVCP. 3. To identify co-morbidities associated with LVCP. 4. To determine the frequency of pre- and post-operative nasopharyngolaryngoscopic (NPL) examination in this patient population. Retrospective chart review of all infants who underwent PDA ligation surgery at a tertiary care academic hospital between July 2003 and July 2010. Data on patient age, gender, weight, method of PDA ligation, and results of NPL scoping were collected, as well as patient co-morbidities post PDA ligation. One hundred and fifteen patients underwent PDA ligation surgery. Four patients were excluded due to bilateral vocal cord paralysis. Of the remaining 111 patients, nineteen patients (17.1%) were found to have LVCP. Low birth weight was identified as a significant risk factor for LVCP (p=0.002). Gastroesophageal reflux was identified as a significant co-morbidity associated with LVCP post PDA ligation (p=0.002). Only 0.9% of patients were scoped pre-operatively, and 27.9% were scoped postoperatively. LVCP is associated with multiple morbidities. The authors strongly recommend routine post-operative scoping of all patients post PDA ligation surgery, and preoperative scoping when possible. A prospective study is warranted, in order to confirm the prevalence of LVCP as well as risk factors and associated co-morbidities. Crown Copyright © 2012. Published by Elsevier Ireland Ltd.

Voss, M; Floderus, B; Diderichsen, F

2001-01-01

OBJECTIVE—To analyse incidence of sickness for women and men relative to potential aetiological factors at work—physical, psychosocial, and organisational.
METHODS—The study group comprised 1557 female and 1913 male employees of Sweden Post. Sickness absence was measured by incidence of sickness (sick leave events and person-days at risk). Information on explanatory factors was obtained by a postal questionnaire, and incidence of sickness was based on administrative files of the company.
RESULTS—Complaints about heavy lifting and monotonous movements were associated with increased risk of high incidence of sickness among both women and men. For heavy lifting, an odds ratio (OR) of 1.70 (95% confidence interval (95% CI) 1.22 to 2.39) among women, and OR 1.70 (1.20 to 2.41) among men was found. For monotonous movements the risk estimates were OR 1.42 (1.03 to 1.97) and OR 1.45 (1.08 to 1.95) for women and men, respectively. Working instead of taking sick leave when ill, was more prevalent in the group with a high incidence of sickness (OR 1.74 (1.30 to 2.33) for women, OR 1.60 (1.22 to 2.10) for men). Overtime work of more than 50 hours a year was linked with low incidence of sickness for women and men. Among women, 16% reported bullying at the workplace, which was linked with a doubled risk of high incidence of sickness (OR 1.91 (1.31 to 2.77)). For men, the strongest association was found for those reporting anxiety about reorganisation of the workplace (OR 1.93 (1.34 to 2.77)).
CONCLUSIONS—Certain physical, psychosocial, and organisational factors were important determinants of incidence of sickness, independently of each other. Some of the associations were sex specific.

Intimate partner violence (IPV) experienced by pregnant and post-partum women has negative health effects for women, as well as the foetus, and the new-born child. In this study we sought to assess the prevalence and factors associated with recent IPV amongst post-partum women in one clinic in eThekwini Municipality, South Africa, and explore the relationship between IPV, depression and functional limitations/disabilities. Past 12 month IPV-victimisation was 10.55%. Logistic regression modelled relationships between IPV, functional limitations, depressive symptoms, socio-economic measures, and sexual relationship power. In logistic regression models, overall severity of functional limitations were not associated with IPV-victimisation when treated as a continuous overall score. In this model relationship power (aOR0.22, p = 0.001) and depressive symptoms (aOR1.26, p = 0.001) were significant. When the different functional limitations were separated out in a second model, significant factors were relationship power (aOR0.20, p = 0.001), depressive symptoms (aOR1.20, p = 0.011) and mobility limitations (aOR2.96, p = 0.024). The study emphasises that not all functional limitations are associated with IPV-experience, that depression and disability while overlapping can also be considered different drivers of vulnerability, and that women's experience of IPV is not dependent on pregnancy specific factors, but rather wider social factors that all women experience.

To evaluate the occurrence of Post-Traumatic Stress Disorder among women experiencing a severe maternal morbidity event and associated factors in comparison with those without maternal morbidity. In a retrospective cohort study, 803 women with or without severe maternal morbidity were evaluated at 6 months to 5 years postpartum for the presence of Post-Traumatic Stress Disorder. Interviews were conducted by telephone and electronic data was stored. Data analysis was carried out by using χ2, Fisher's Exact test, and logistic regression analysis. There was no significant change in the prevalence of Post-Traumatic Stress Disorder related to a previous severe maternal morbidity experience. There were also no differences in diagnostic criteria for severe maternal morbidity (hypertensive syndromes, hemorrhage, surgical intervention or intensive care unit admission required, among other management criteria). Low parity (2.5-fold risk) and increasing age were factors associated with Post-Traumatic Stress Disorder. A severe maternal morbidity episode is not associated with Post-Traumatic Stress Disorder symptoms within five years of the severe maternal morbidity event and birth. However, a more advanced maternal age and primiparity increased the risk of Post-Traumatic Stress Disorder. This does not imply that women who had experienced a severe maternal morbidity event did not suffer or need differentiated care.

Full Text Available Background: Reactive arthritis (ReA/Reiter′s syndrome (RS may be caused as a sequel of infections caused by enteric bacterial pathogens, although the mechanisms through, which different pathogens cause similar disease are not clear. Aim: This study was done to look for the presence and role of any common bacterial antigen among the pathogens isolated from such patients. Materials and Methods: A total of 51 patients of ReA and 75 controls (three groups of 25 subjects each: Group 1: Patients who did not develop arthritic complications within 3 months after bacillary dysentery/diarrhea; Group 2: Patients with other arthritic diseases and Group 3: Normal healthy subjects were included. The isolated enteric pathogens were tested to detect the immunodominant antigens. Results and Conclusions: A common 30 kDa antigen was found to be specifically present among seven arthritogenic enteric bacterial strains belonging to three genera, Salmonella, Shigella and Hafnia. Post-dysenteric ReA patients′ sera show higher levels of immunoglobulin G, immunoglobulin M and immunoglobulin A antibodies against this antigen as compared to the controls. Lymphocytes of ReA patients recognize this antigen, proliferate and produce interleukin-2 in response to this antigen more than the lymphocytes of controls. 30 kDa antigen may be a common arthritogenic factor associated with post-dysenteric ReA/RS. The association of Hafnia alvei with post-dysenteric ReA is described for the first time. Four cases of mycobacterial ReA had an association with this antigen, suggesting that the arthritogenic antigen of mycobacteria and enteric bacteria may be of a similar nature.

Nursing students in the present sample who have experienced childhood adversity have a certain level of post-traumatic growth. If introduced into nursing curricula, emotional intelligence interventions may increase emotional coping resources and enhance social skills for nurses, which may benefit their long-term occupational health. As researchers consider personal resilience a strategy for responding to workplace adversity in nurses, resilience building should be incorporated into nursing education. This is a preliminary study that may guide future investigations of the curvilinear relationship rather than linear relationship between post-traumatic growth and positive factors in the special sample of nursing students. Resilience, emotional intelligence and post-traumatic growth may benefit nursing students' careers and personal well-being in clinical work. Developing both their emotional intelligence and resilience may assist their individual post-traumatic growth and enhance their ability to cope with clinical stress. To investigate the relationships among post-traumatic growth, emotional intelligence and psychological resilience in vocational school nursing students who have experienced childhood adversities, a cross-sectional research design with anonymous questionnaires was conducted and self-report data were analysed. The Childhood Adversities Checklist (Chinese version), Posttraumatic Growth Inventory, Emotional Intelligence Scale and the 10-item Connor-Davidson Resilience Scale were used. Survey data were collected from 202 Chinese vocational school nursing students during 2011. Post-traumatic growth was associated with emotional intelligence and psychological resilience. Results indicated a curvilinear relationship between emotional intelligence and post-traumatic growth, and between psychological resilience and post-traumatic growth. Moderate-level emotional intelligence and psychological resilience were most associated with the greatest levels of growth

A post hoc analysis of a randomized controlled trial comparing the clinical effects of furosemide and ethacrynic acid was conducted. Infants undergoing cardiac surgery with cardiopulmonary bypass were included in order to explore which clinical factors are associated with diuretic dose in infants with congenital heart disease. Overall, 67 patients with median (interquartile range) age of 48 (13-139) days were enrolled. Median diuretic dose was 0.34 (0.25-0.4) mg/kg/h at the end of postoperative day (POD) 0 and it significantly decreased (p = 0.04) over the following PODs; during this period, the ratio between urine output and diuretic dose increased significantly (p = 0.04). Age (r -0.26, p = 0.02), weight (r -0.28, p = 0.01), cross-clamp time (r 0.27, p = 0.03), administration of ethacrynic acid (OR 0.01, p = 0.03), and, at the end of POD0, creatinine levels (r 0.3, p = 0.009), renal near-infrared spectroscopy saturation (-0.44, p = 0.008), whole-blood neutrophil gelatinase-associated lipocalin levels (r 0.30, p = 0.01), pH (r -0.26, p = 0.02), urinary volume (r -0.2755, p = 0.03), and fluid balance (r 0.2577, p = 0.0266) showed a significant association with diuretic dose. At multivariable logistic regression cross-clamp time (OR 1.007, p = 0.04), use of ethacrynic acid (OR 0.2, p = 0.01) and blood pH at the end of POD0 (OR 0.0001, p = 0.03) was independently associated with diuretic dose. Early resistance to loop diuretics continuous infusion is evident in post-cardiac surgery infants: Higher doses are administered to patients with lower urinary output. Independently associated variables with diuretic dose in our population appeared to be cross-clamping time, the administration of ethacrynic acid, and blood pH.

Broad-Scale Environmental Conditions Responsible for Post-Fire Vegetation Dynamics

2010-11-01

Full Text Available Ecosystem response to disturbance is influenced by environmental conditions at a number of scales. Changes in climate have altered fire regimes across the western United States, and have also likely altered spatio-temporal patterns of post-fire vegetation regeneration. Fire occurrence data and a vegetation index (NDVI derived from the NOAA Advanced Very High Resolution Radiometer (AVHRR were used to monitor post-fire vegetation from 1989 to 2007. We first investigated differences in post-fire rates of vegetation regeneration between ecoregions. We then related precipitation, temperature, and elevation records at four temporal scales to rates of post-fire vegetation regeneration to ascertain the influence of climate on post-fire vegetation dynamics. We found that broad-scale climate factors are an important influence on post-fire vegetation regeneration. Most notably, higher rates of post-fire regeneration occurred with warmer minimum temperatures. Increases in precipitation also resulted in higher rates of post-fire vegetation growth. While explanatory power was slight, multiple statistical approaches provided evidence for real ecological drivers of post-fire regeneration that should be investigated further at finer scales. The sensitivity of post-disturbance vegetation dynamics to climatic drivers has important ramifications for the management of ecosystems under changing climatic conditions. Shifts in temperature and precipitation regimes are likely to result in changes in post-disturbance dynamics, which could represent important feedbacks into the global climate system.

Hovhannisyan, Lilit; Stepanyan, Ani; Arakelyan, Arsen

2017-10-01

Individual susceptibility to post-traumatic stress disorder (PTSD) is conditioned by genetic factors, and association between this disorder and polymorphisms of several genes have been shown. The aim of this study was to explore a potential association between single nucleotide polymorphisms (SNP) of the IL-1β gene (IL1B) and PTSD. In genomic DNA samples of PTSD-affected and healthy subjects, the rs16944, rs1143634, rs2853550, rs1143643, and rs1143633 SNPs of IL1B gene have been genotyped. The results obtained demonstrated that IL1B rs1143633*C and rs16944*A minor allele frequency were significantly lower in patients than in controls. Our results confirm that IL1B rs1143633 and rs16944 SNPs are negatively associated with PTSD which allows us to consider them as protective variants for PTSD. IL1B rs1143633*C and rs16944*A minor allele frequencies and carriage rates are significantly lower in the PTSD patients as compared to the controls. These results may provide a base to conclude that above-mentioned alleles can be protective against PTSD, and IL1B gene can be involved in the pathogenesis of this disorder.

Donor notification and counselling transforms the legal and ethical requirement of disclosure of transfusion transmissible infection (TTI) in a blood donor into practice. The present study was done to assess the response to the disclosure of TTI reactivity results in blood donors, assess the risk factors in blood donors and follow the compliance of the disclosure and clinical referral in a population of blood donors who are difficult to convince that they may be harbouring infections apparently in a healthy state today but with possible clinical disease consequences in the future. A retrospective study was conducted from April 2011 to November 2012. Screening was done using third generation ELISA kits used according to the manufacturer's directions; these kits were approved for use in blood banks by the Drug Controller General of India. Those testing repeat reactive were referred for further confirmation and management. The total number of TTI reactive donors was 787 (0.93 %, N = 83,865). The observed response rate in the present study is 21.6 % (167, N = 787). The risk factors for acquiring infections in TTI reactive donors were statistically significant history of high risk behaviour (20.3 %) for human immunodeficiency virus infection and history of jaundice in themselves, family or close contacts (16.1 %) for hepatitis B virus infection. One hundred and ten (65.8 %) of the referred donors were on outpatient clinical care when post-referral follow up was conducted. The study emphasises on continuing sensitization of blood donation camp organisers to the need of privacy during blood donor selection. The study also stresses the need to strengthen the pre-donation counselling at outdoor blood donation at the same time raise awareness amongst blood donors about the importance of post-donation counselling and follow up.

What is known on the subject? This study builds on existing research on war-related factors that may affect health-care staff by particularly focusing on trauma exposure in both professional and everyday life, as well as on correlates of later positive psychological changes. What this paper adds to existing knowledge? It shows that one in five nursing staff working in Gaza experienced post-traumatic stress symptoms within the clinical range, 2 years after an incursion on Gaza and after being exposed to substantial trauma during this period. Participants appeared to develop a variety of post-traumatic growth responses following trauma exposure. Although nurses experienced traumatic events both as civilians and in their health-care capacity, personal exposure was strongly associated with PTSD symptoms. What are the implications for practice? Support to nursing and other health-care professionals in war situations should entail different levels, remain available well after an acute conflict, and take into consideration both personal and practice-related traumatic events. Mental health nursing practitioners can play a pivotal role in this. To establish the association between war traumatic experiences, post-traumatic stress disorder (PTSD) symptoms and post-traumatic growth among nurses in the Gaza Strip, 2 years after an incursion on Gaza, and during a period of ongoing trauma exposure. This study builds on existing evidence by considering exposure to personal and work-related traumatic events, and on factors associated with later positive psychological adaptation. The sample consisted of 274 randomly selected nurses in Gaza who completed the Gaza Traumatic Events Checklist, PTSD Checklist, and Posttraumatic Growth Inventory. Of the nurses, 19.7% reported full PTSD. There was a significant relationship between traumatic events and PTSD scores; as well as between community-related traumatic events and post-traumatic growth. Participants reported a range of traumatic
