Haemodynamic assessment following inferior vena cava resection without replacement

Background: Treatment of bulky retroperitoneal malignancy may require en bloc resection of the infrarenal inferior vena cava. A number of reconstructive options are available to the surgeon but objective haemodynamic assessment of the peripheral venous system following resection without replacement is lacking. The aim of the present paper was thus to determine the symptomatic and haemodynamic effects of not reconstructing the resected infrarenal inferior vena cava. Methods: A retrospective descriptive study was carried out at Princess Alexandra Hospital in Queensland. Five patients underwent resection of the thrombosed infrarenal inferior vena cava as part of retroperitoneal lymph node dissection for testicular cancer (n = 3), radical nephrectomy for renal cell carcinoma (n = 1) and thrombosed inferior vena cava aneurysm (n = 1). Clinical effects were determined via the modified venous clinical severity score and venous disability score. Haemodynamic data were obtained postoperatively using venous duplex ultrasound and air plethysmography. Results: None of the present patients scored >2 (out of 30) on the modified venous clinical severity score or >1 (out of 3) on the venous disability score. Haemodynamic studies showed only minor abnormalities. Conclusions: Not reconstructing the resected thrombosed infrarenal inferior vena cava results in minor signs and symptoms of peripheral venous hypertension and only minor abnormalities on haemodynamic assessment.

Validating the functional capacity index: A comparison of predicted versus observed total body scores

Background: The Functional Capacity Index (FCI) was designed to predict physical function 12 months after injury. We report a validation study of the FCI. Methods: This was a consecutive case series registered in the Queensland Trauma Registry who consented to the prospective 12-month telephone-administered follow-up study. FCI scores measured at 12 months were compared with those originally predicted. Results: Complete Abbreviated Injury Scale score information was available for 617 individuals, of whom 587 (95%) could be assigned at least one FCI score (range, 1-17). Agreement between the largest predicted FCI and observed FCI score was poor (kappa = 0.05; 95% confidence interval, 0.00-0.10) and explained only 1% of the variability in observed FCI. Using an encompassing model that included all FCI assignments, agreement remained poor (kappa = 0.05; 95% confidence interval, -0.02-0.12), and the model explained only 9% of the variability in observed FCI. Conclusion: The predicted functional capacity poorly agrees with actual functional outcomes. Further research should consider including other (noninjury) explanatory factors in predicting FCI at 12 months.

Antenatal corticosteroids impact the inflammatory rather than the antiangiogenic profile of women with preeclampsia

Circulating antiangiogenic factors and proinflammatory cytokines are implicated in the pathogenesis of preeclampsia. This study was performed to test the hypothesis that steroids modify the balance of inflammatory and proangiogenic and antiangiogenic factors that potentially contribute to the patient’s evolving clinical state. Seventy singleton women, admitted for antenatal corticosteroid treatment, were enrolled prospectively. The study group consisted of 45 hypertensive women: chronic hypertension (n=6), severe preeclampsia (n=32), and superimposed preeclampsia (n=7). Normotensive women with shortened cervix (<2.5 cm) served as controls (n=25). Maternal blood samples of preeclampsia cases were obtained before steroids and then serially up until delivery. A clinical severity score was designed to clinically monitor disease progression. Serum levels of angiogenic factors (soluble fms-like tyrosine kinase-1 [sFlt-1], placental growth factor [PlGF], soluble endoglin [sEng]), endothelin-1 (ET-1), and proinflammatory markers (IL-6, C-reactive protein [CRP]) were assessed before and after steroids. Soluble IL-2 receptor (sIL-2R) and total immunoglobulins (IgG) were measured as markers of T- and B-cell activation, respectively. Steroid treatment coincided with a transient improvement in clinical manifestations of preeclampsia. A significant decrease in IL-6 and CRP was observed although levels of sIL-2R and IgG remained unchanged. Antenatal corticosteroids did not influence the levels of angiogenic factors but ET-1 levels registered a short-lived increase poststeroids. Although a reduction in specific inflammatory mediators in response to antenatal steroids may account for the transient improvement in clinical signs of preeclampsia, inflammation is unlikely to be the major contributor to severe preeclampsia or useful for therapeutic targeting.

The relationship between participation in unethical behaviors during the nursing student experience and participation in unethical behaviors as a registered nurse

The effect of unethical behaviors in health care settings is an important issue in the safe care of clients and has been a concern of the nursing profession for some time. The purpose of this study was to examine the relationship between use of unethical behaviors in the nursing student experience and the use of unethical behaviors in the workplace as a registered nurse. In addition, the relationship between the severity of unethical behaviors utilized in the classroom, clinical setting and those in the workplace was examined. To insure greater honesty in self-report, only a limited number of demographic variables were requested from participants.^ During the summer of 1997, a 56 item questionnaire was distributed to registered nurses enrolled in either undergraduate or graduate courses in a public or private institution. The participants were asked to self-report their own use of unethical behaviors as well as their peers use of unethical behaviors. In order to assign a severity score for each item, nursing school faculty were asked to rate severity of unethical behaviors which could be used during the nursing student experience and nursing administrators were asked to rate unethical behaviors which could be used in the workplace.^ A significant positive relationship was found between individuals' use of unethical behaviors during nursing school and those used in the workplace $r=.630.$ A significant positive relationship was found between the severity of unethical behaviors used in the nursing student experience and the severity of unethical behaviors used in the workplace $r=.637.$ No relationship was found between years of practice, type of initial nursing education and whether or not the participant was raised inside or outside the United States and the use of unethical behaviors. ^

The effects of defendant account on damage award decisions

The purpose of this study was to examine whether the manner in which civil defendants account for their behavior influences compensatory and punitive damage awards. Jurors read three civil trial summaries, in which I manipulated injury severity (high vs. low), defendant reprehensibility (high vs. low), defendant status (individual vs. corporate), and account (concession, excuse, justification or refusal) in a factorial design. I also included four control groups in which the defendant stipulated liability. In all other conditions, participants read that a jury had found the defendant negligent. Only defendant reprehensibility influenced punitive awards. Both plaintiff injury and defendant reprehensibility influenced compensatory awards. When individuals offered justifications and when corporations offered excuses, jurors awarded lower compensatory awards against low reprehensibility defendants than against high reprehensibility defendants. Negligence stipulations led to lower damage awards for individuals than for corporations. Additionally, concessions tended to produce lower awards when combined with a stipulation of negligence as opposed to a jury decision. These findings support the hypothesis that in cases in which the defendant is clearly negligent, circumstances exist in which stipulating negligence and offering an apologetic account will lead to reduced damage awards decisions. Results indicate that individual and corporate defendants offering justifications and refusals should first consider the reprehensibility of their actions. In a broader realm, findings demonstrate that the manner in which a jury perceives the explanation given by the defendant is dependent upon defendant characteristics and case-specific factors. ^

Trajetórias e fatores associados a qualidade de vida de mães de recém-nascidos pré-termos de muito baixo peso até três anos após o parto

Preterm birth is a public health problem worldwide. It holds growing global incidence rates, high mortality rates and a risk of the long-term sequelae in the newborn. It is also poses burden on the family and society. Mothers of very low birth weight (VLBW) preterm infants may develop psychological disorders, and impaired quality of life (QoL). Factors related to mothers and children in the postpartum period may be negatively associated with the QoL of these mothers. The aim of this study was to assess factors possibly associated with the QoL of mothers of VLBW preterm newborns during the first three years after birth. Mothers of VLBW preterm answered the World Health Organization Quality of Life (WHOQOL)-bref and the Beck Depression Inventory (BDI) in five time points up to 36 months postpartum, totalizing 260 observations. The WHOQOL–bref scores were compared and correlated with sociodemographic and clinical variables of mothers and children at discharge (T0) and at six (T1), twelve (T2), 24 (T3) and 36 (T4) months after the delivery. We used the Kruskal Wallis test to compared scores across different time points and correlated WHOQOL-bref scores with the sociodemographic and clinical variables of mothers and preterm infants. Multiple linear regression models were used to evaluate the contribution of these variables for the QoL of mothers. The WHOQOL–bref scores at T1 and T2 were higher when compared to scores in T0 in the physical health dimension (p = 0.013). BDI scores were also higher at T1 and T2 than those at T0 (p = 0.027). Among the maternal variables that contributed most to the QoL of mothers, there were: at T0, stable marital union (b= 13.60; p= 0.000) on the social relationships dimension, gestational age (b= 2.38; p= 0.010) in the physical health dimension; post-hemorrhagic hydrocephalus (b= -10.05; p= 0.010; b= -12.18; p= 0.013, respectively) in the psychological dimension; at T1 and T2, Bronchopulmonary dysplasia (b= -7.41; p= 0.005) and female sex (b= 8,094; p= 0.011) in the physical health dimension and environment, respectively. At T3, family income (b= -12.75’ p= 0.001) in the environment dimension, the SNAPPE neonatal severity score (b= -0.23; p= 0.027) on the social relationships dimension; at the T4, evangelical religion (b= 8.11; p= 0.019) and post-hemorrhagic hydrocephalus (b: -18.84 p: 0.001) on the social relationships dimension. The BDI scores were negatively associated with WHOQOL scores in all dimensions and at all times points: (-1.42 ≤ b ≤ -0.36; T0, T1, T2, T3 and T4). We conclude that mothers of preterm infants VLBW tend to have a transient improvement in the physical well-being during the first postpartum year. Their quality of life seems to return to levels at discharge between two and three years after delivery. The presence of maternal depressive symptoms and diagnosis of post-hemorrhagic hydrocephalus or BDP are factors negatively associated with the QoL of mothers. Social, religious and economic variables are positively associated with the QoL of mothers of VLBW preterm.

Traitement des émotions évoquées par les expressions faciales, vocales et musicales à la suite d’un traumatisme craniocérébral

Le traitement des émotions joue un rôle essentiel dans les relations interpersonnelles. Des déficits dans la reconnaissance des émotions évoquées par les expressions faciales et vocales ont été démontrés à la suite d’un traumatisme craniocérébral (TCC). Toutefois, la majorité des études n’ont pas différencié les participants selon le niveau de gravité du TCC et n’ont pas évalué certains préalables essentiels au traitement émotionnel, tels que la capacité à percevoir les caractéristiques faciales et vocales, et par le fait même, la capacité à y porter attention. Aucune étude ne s’est intéressée au traitement des émotions évoquées par les expressions musicales, alors que la musique est utilisée comme méthode d’intervention afin de répondre à des besoins de prise en charge comportementale, cognitive ou affective chez des personnes présentant des atteintes neurologiques. Ainsi, on ignore si les effets positifs de l’intervention musicale sont basés sur la préservation de la reconnaissance de certaines catégories d’émotions évoquées par les expressions musicales à la suite d’un TCC. La première étude de cette thèse a évalué la reconnaissance des émotions de base (joie, tristesse, peur) évoquées par les expressions faciales, vocales et musicales chez quarante et un adultes (10 TCC modéré-sévère, 9 TCC léger complexe, 11 TCC léger simple et 11 témoins), à partir de tâches expérimentales et de tâches perceptuelles contrôles. Les résultats suggèrent un déficit de la reconnaissance de la peur évoquée par les expressions faciales à la suite d’un TCC modéré-sévère et d’un TCC léger complexe, comparativement aux personnes avec un TCC léger simple et sans TCC. Le déficit n’est pas expliqué par un trouble perceptuel sous-jacent. Les résultats montrent de plus une préservation de la reconnaissance des émotions évoquées par les expressions vocales et musicales à la suite d’un TCC, indépendamment du niveau de gravité. Enfin, malgré une dissociation observée entre les performances aux tâches de reconnaissance des émotions évoquées par les modalités visuelle et auditive, aucune corrélation n’a été trouvée entre les expressions vocales et musicales. La deuxième étude a mesuré les ondes cérébrales précoces (N1, N170) et plus tardives (N2) de vingt-cinq adultes (10 TCC léger simple, 1 TCC léger complexe, 3 TCC modéré-sévère et 11 témoins), pendant la présentation d’expressions faciales évoquant la peur, la neutralité et la joie. Les résultats suggèrent des altérations dans le traitement attentionnel précoce à la suite d’un TCC, qui amenuisent le traitement ultérieur de la peur évoquée par les expressions faciales. En somme, les conclusions de cette thèse affinent notre compréhension du traitement des émotions évoquées par les expressions faciales, vocales et musicales à la suite d’un TCC selon le niveau de gravité. Les résultats permettent également de mieux saisir les origines des déficits du traitement des émotions évoquées par les expressions faciales à la suite d’un TCC, lesquels semblent secondaires à des altérations attentionnelles précoces. Cette thèse pourrait contribuer au développement éventuel d’interventions axées sur les émotions à la suite d’un TCC.
