Portuguese validation of the Symptom Inventory of the M.D. Anderson Cancer Center

Objective To analyze the reliability and validity of the psychometric properties of the Brazilian version of the instrument for symptom assessment, titled MD Anderson Symptom Inventory - core. Method A cross-sectional study with 268 cancer patients in outpatient treatment, in the municipality of Ijuí, state of Rio Grande do Sul, Brazil. Results The Cronbach’s alpha for the MDASI general, symptoms and interferences was respectively (0.857), (0.784) and (0.794). The factor analysis showed adequacy of the data (0.792). In total, were identified four factors of the principal components related to the symptoms. Factor I: sleep problems, distress (upset), difficulties in remembering things and sadness. Factor II: dizziness, nausea, lack of appetite and vomiting. Factor III: drowsiness, dry mouth, numbness and tingling. Factor IV: pain, fatigue and shortness of breath. A single factor was revealed in the component of interferences with life (0.780), with prevalence of activity in general (59.7%), work (54.9%) and walking (49.3%). Conclusion The Brazilian version of the MD Anderson Symptom Inventory - core showed adequate psychometric properties in the studied population.

Caring for family caregivers: An analysis of a family-centered intervention

Objective To assess the effectiveness of Problem-Solving Therapy (PST) on family caregivers through the use of scales to measure anxiety, depression and emotional distress; and to explore facilitating factors and obstacles for its use based on the narrative of nurses. Method A clinical trial and an exploratory focus group with the use of mixed analysis methodology. The study was conducted in a primary health care center in Tarragona, Spain, and the sample consisted of 122 family caregivers who were included in the home care service, and 10 nurses who participated in the intervention group. Family caregivers with evident symptoms of anxiety, depression and emotional distress received PST in the intervention group. The intervention group also consisted of a discussion with eight nurses, which was transcribed and submitted to content analysis. Conclusion Problem-Solving Therapy proved to be effective in reducing perceived anxiety, depression and emotional distress. We identified its strong points and obstacles as described by nurses.



Assessing dispositional empathy in adults: A French validation of the Interpersonal Reactivity Index (IRI).

The goal of this study was to validate a French version of the Interpersonal Reactivity Index (IRI), a self-report questionnaire comprised of four subscales assessing affective (empathic concern and personal distress) and cognitive (fantasy and perspective taking) components of empathy. To accomplish this, 322 adults (18 to 89 years) completed the French version of the IRI (F-IRI). A confirmatory factor analysis confirmed the four-factor structure of the original IRI. The F-IRI showed good scale score reliability, test-retest reliability, and convergent validity, tested with the French version of the Empathy Quotient. These findings confirmed the reliability and validity of the F-IRI and suggest that the F-IRI is a useful instrument to measure self-reported empathy. In addition, we observed sex and age differences consistent with findings in the literature. Women reported higher scores in empathic concern and fantasy than men. Older adults reported less personal distress and less fantasy. (PsycINFO Database Record (c) 2013 APA, all rights reserved)

Dysfunctional psychological responses among Intensive Care Unit nurses: a systematic review of the literature

AbstractOBJECTIVETo systematically review evidence on dysfunctional psychological responses of Intensive Care Units nurses (ICUNs), with focus on anxiety and depressive symptoms and related factors.METHODA literature search was performed in CINAHL, PubMed and Scopus databases, from 1999 to present, along with a critical appraisal and synthesis of all relevant data. The following key words, separately and in combination, were used: "mental status" "depressive symptoms" "anxiety" "ICU nurses" "PTSD" "burnout" "compassion fatigue" "psychological distress".RESULTSThirteen quantitative studies in English and Greek were included. The results suggested increased psychological burden in ICUNs compared to other nursing specialties, as well as to the general population.CONCLUSIONSStudies investigating psychological responses of ICUNs are limited, internationally. Future longitudinal and intervention studies will contribute to a better understanding of the phenomenon.

A la recherche de symptômes de désorientation dépendant d'un déficit d'intégration multisensorielle chez l'animal : un éclairage sur les mécanismes fondamentaux de la schizophrénie

Abstract Fundamental research in psychiatric neurosciences assumes that psychiatric disorders are associated with neurobiological factors. Identification of these factors would provide therapeutic targets as well as a better understanding of the relationship between- brain and behaviour in pathological processes. We conducted experiments in an animal model of schizophrenia. Several behavioural tasks were used to evaluate spatial and working memory in these animals. The model is based on glutathione deficit during cerebral development. Indeed, a 50% decrease of glutathione has been reported in prefrontal cortex of patients with schizophrenia. Glutathione is a major antioxidant in the brain and its deficit could lead to abnormal brain connectivity. The glutathione deficit was induced in rats by perinatal (PS-P16) subcutaneous injections with Lbuthionine-(S,R)-sullfoximine (BSO), an inhibitor of glutathione synthesis. This treatment leads to a transitory 50% glutathione levels during brain development. In parallel, we conducted behavioural testing in rats with a medial prefrontal cortex lesion. This allowed us to compare early damage induced by BSO treatment with a focal lesion in adults of a brain area known to present anomalies in schizophrenia. Finally, we conducted a series of experiments in senescent rats to evaluate if cognitive deficits could be related to neurobiological changes. Our results show that an early glutathione deficit provokes cognitive deficits in adulthood. These spatial and working memory deficits resemble the cognitive deficits observed in schizophrenia. The comparison with prefrontal rats revealed that the early brain glutathione deficit provoked more severe cognitive deficits than the prefrontal lesion in adult rats. Moreover, in both cases, we observed a dissociation in memory deficits depending on the type of locomotion that was used in behavioural experiments. Indeed, BSO treated rats as well as prefrontal rats showed place learning or working memory deficits in tasks conducted on dry surfaces where they had to walk. In contrast, they showed no deficit when the same cognitive functions were tested in the water maze. This dissociation might be sustained by a difference in requirement of sensory integration between walking and swimming tasks. Résumé La recherche fondamentale en neurosciences psychiatriques repose sur le présupposé selon lequel les symptômes manifestés dans les troubles psychiatriques auraient des concomitants neurobiologiques. Ceux-ci, une fois identifiés, offriraient des cibles pour une démarche thérapeutique ainsi que des modèles permettant de mieux comprendre les soubassements biologiques du comportement et des activités mentales. Nos expériences s'articulent autour de la question de la modélisation de la schizophrénie chez l'animal. Nous avons recherché chez ces animaux des troubles cognitifs et sensoriels associés à la schizophrénie. En effet, chez l'homme comme chez l'animal, la mémoire spatiale et la mémoire de travail dépendent fortement de la capacité d'intégration et d'organisation des informations sensorielles. Les premières expériences ont été menées suite à une perturbation périnatale du développement cérébral. Celle-ci visait à reproduire une diminution du taux de glutathion dans le cerveau, des recherches précédentes ayant observé une diminution de 50% du taux de glutathion dans le cortex préfrontal de patients schizophrènes. Le glutathion étant un antioxydant majeur dans le cerveau, son déficit pourrait conduire à des perturbations de la circuiterie cérébrale. Nous avons reproduit ce déficit chez le rat, par injection de Lbuthionine-(S,R)-sullfoximine (BSO), un inhibiteur de la synthèse du glutathion... Ce traitement a été administré pendant la période périnatale (du jour postnatal 5 au jour 16) provoquant une diminution de 50% du taux de glutathion. Nous avons ensuite évalué lës répercussions de cette atteinte précoce sur le comportement des rats à l'âge adulte. Ce modèle s'inscrit donc dans l'hypothèse neurodéveloppementale qui associe la schizophrénie à une atteinte du développement cérébral normal. Nous avons ensuite conduit des expériences similaires chez des rats ayant subi une lésion du cortex préfrontal pour comparer les répercussions du traitement périnatal avec une lésion, à l'âge adulte, d'une aire cérébrale connue pour présenter des anomalies chez les patients. Finalement, nous avons évalué si les processus sensoriels et cognitifs précédemment étudiés pouvaient également être affectés lors du vieillissement normal en recherchant des corrélats biologiques des déficits de mémoire liés à l'âge avancé. Nos résultats montrent que ce déficit précoce en glutathion peut avoir des répercussions surale comportement à l'âge adulte. On a relevé une similarité avec les déficits cognitifs associés.à la schizophrénie, incluant des déficits de mémoire de travail ainsi que des déficits de mémoire spatiale. Ces déficits étaient fortement liés au type de locomotion utilisée et n'ont été observés que dans les tâches où les animaux devaient rejoindre un but en marchant mais pas dans lés tests dans lesquels ils devaient localiser une cible en nageant. Les déficits induits par la lésion préfrontale chez l'adulte étaient beaucoup plus légers que ceux découlant de l'atteinte périnatale mais présentaient une dissociation analogue en fonction du type de locomotion. De plus, des tests similaires menés au cours du vieillissement confirment que la mémoire de travail peut être affectée sélectivement par le vieillissement dans une tâche où les animaux doivent marcher, tout en restant intacte dans le bassin de Morris. Les déficits cognitifs liés au vieillissement étaient significativement corrélés à des différences de niveaux des protéines post-synaptiques PSD95 (postsynaptic density 95). L'ensemble des résultats montre que les tests qui sont fréquemment utilisés pour évaluer la mémoire chez l'animal pourraient faire appel à des processus différents. Cette différence pourrait notamment tenir au niveau d'intégration sensorielle requis pour résoudre la tâche, qui est particulièrement sollicitée au cours d'une locomotion intermittente.

Exome Sequencing Identifies INPPL1 Mutations as a Cause of Opsismodysplasia.

Opsismodysplasia (OPS) is a severe autosomal-recessive chondrodysplasia characterized by pre- and postnatal micromelia with extremely short hands and feet. The main radiological features are severe platyspondyly, squared metacarpals, delayed skeletal ossification, and metaphyseal cupping. In order to identify mutations causing OPS, a total of 16 cases (7 terminated pregnancies and 9 postnatal cases) from 10 unrelated families were included in this study. We performed exome sequencing in three cases from three unrelated families and only one gene was found to harbor mutations in all three cases: inositol polyphosphate phosphatase-like 1 (INPPL1). Screening INPPL1 in the remaining cases identified a total of 12 distinct INPPL1 mutations in the 10 families, present at the homozygote state in 7 consanguinous families and at the compound heterozygote state in the 3 remaining families. Most mutations (6/12) resulted in premature stop codons, 2/12 were splice site, and 4/12 were missense mutations located in the catalytic domain, 5-phosphatase. INPPL1 belongs to the inositol-1,4,5-trisphosphate 5-phosphatase family, a family of signal-modulating enzymes that govern a plethora of cellular functions by regulating the levels of specific phosphoinositides. Our finding of INPPL1 mutations in OPS, a severe spondylodysplastic dysplasia with major growth plate disorganization, supports a key and specific role of this enzyme in endochondral ossification.

What kind of relationships between the evolution of pain, beliefs and bio-psycho-social complexity after a locomotor traumatism?

Introduction: Pain and beliefs have an influence on the patient's course in rehabilitation, pain causes fears and fears influence pain perception. The aim of this study is to understand pain and beliefs evolutions during rehabilitation taking into account of bio-psycho-social complexity.Patients and methods: 631 consecutive patients admitted in rehabilitation after a musculoskeletal traumatism were included and assessed at admission and at discharge. Pain was measured by VAS (Visual Analogical Scale), bio-psycho-social complexity by Intermed scale, and beliefs by judgement on Lickert scales. Four kinds of beliefs were evaluated: fear of a severe origin of pain, fear of movement, fear of pain and feeling of distress (loss of control). The association between the changes in pain and beliefs during the hospitalization was assessed by linear regressions.Results: After adjustment for gender, age, education and native language, patients with a decrease in pain during rehabilitation have higher probability of decreasing their fears. For the distress feeling, this relationship is weaker among bio-psycho-socially complex patients (odds-ratio 1.22 for each decreasing of 10mm/100 VAS) than among non-complex patients (OR 1.47). Patients with a pain decrease of 30% or more during hospitalization have higher probability of seeing their fears decrease, this relationship being stronger in complex patient for fear of a severe origin of pain.Discussion: The relationships between evolution of pain and beliefs move in the same direction. The higher a patient feels pain, the less they could be able to modify their dysfunctional beliefs. When the pain diminishes of 30% or more, the probability to challenge the beliefs is increased. The prognostic with regard to feeling of distress and fear of a severe origin of pain, is worse among bio-psycho-socially complex patients.

Congenital tumors: imaging when life just begins.

BACKGROUND: The technical developments of imaging methods over the last 2 decades are changing our knowledge of perinatal oncology. Fetal ultrasound is usually the first imaging method used and thus constitutes the reference prenatal study, but MRI seems to be an excellent complementary method for evaluating the fetus. The widespread use of both techniques has increased the diagnosis rates of congenital tumors. During pregnancy and after birth, an accurate knowledge of the possibilities and limits of the different imaging techniques available would improve the information obtainable, thus helping the medical team to make the most appropriate decisions about therapy and to inform the family about the prognosis. CONCLUSION: In this review article, we describe the main congenital neoplasms, their prognosis and their imaging characteristics with the different pre- and postnatal imaging methods available.

16q24.1 microdeletion in a premature newborn: Usefulness of array-based comparative genomic hybridization in persistent pulmonary hypertension of the newborn.

OBJECTIVE:: Report of a 16q24.1 deletion in a premature newborn, demonstrating the usefulness of array-based comparative genomic hybridization in persistent pulmonary hypertension of the newborn and multiple congenital malformations. DESIGN:: Descriptive case report. SETTING:: Genetic department and neonatal intensive care unit of a tertiary care children's hospital. INTERVENTIONS:: None. PATIENT:: We report the case of a preterm male infant, born at 26 wks of gestation. A cardiac malformation and bilateral hydronephrosis were diagnosed at 19 wks of gestation. Karyotype analysis was normal, and a 22q11.2 microdeletion was excluded by fluorescence in situ hybridization analysis. A cesarean section was performed due to fetal distress. The patient developed persistent pulmonary hypertension unresponsive to mechanical ventilation and nitric oxide treatment and expired at 16 hrs of life. MEASUREMENTS AND MAIN RESULTS:: An autopsy revealed partial atrioventricular canal malformation and showed bilateral dilation of the renal pelvocaliceal system with bilateral ureteral stenosis and annular pancreas. Array-based comparative genomic hybridization analysis (Agilent oligoNT 44K, Agilent Technologies, Santa Clara, CA) showed an interstitial microdeletion encompassing the forkhead box gene cluster in 16q24.1. Review of the pulmonary microscopic examination showed the characteristic features of alveolar capillary dysplasia with misalignment of pulmonary veins. Some features were less prominent due to the gestational age. CONCLUSIONS:: Our review of the literature shows that alveolar capillary dysplasia with misalignment of pulmonary veins is rare but probably underreported. Prematurity is not a usual presentation, and histologic features are difficult to interpret. In our case, array-based comparative genomic hybridization revealed a 16q24.1 deletion, leading to the final diagnosis of alveolar capillary dysplasia with misalignment of pulmonary veins. It emphasizes the usefulness of array-based comparative genomic hybridization analysis as a diagnostic tool with implications for both prognosis and management decisions in newborns with refractory persistent pulmonary hypertension and multiple congenital malformations.

Lack of Smad3 signaling leads to impaired skeletal muscle regeneration.

Smad3 is a key intracellular signaling mediator for both transforming growth factor-β and myostatin, two major regulators of skeletal muscle growth. Previous published work has revealed pronounced muscle atrophy together with impaired satellite cell functionality in Smad3-null muscles. In the present study, we have further validated a role for Smad3 signaling in skeletal muscle regeneration. Here, we show that Smad3-null mice had incomplete recovery of muscle weight and myofiber size after muscle injury. Histological/immunohistochemical analysis suggested impaired inflammatory response and reduced number of activated myoblasts during the early stages of muscle regeneration in the tibialis anterior muscle of Smad3-null mice. Nascent myofibers formed after muscle injury were also reduced in number. Moreover, Smad3-null regenerated muscle had decreased oxidative enzyme activity and impaired mitochondrial biogenesis, evident by the downregulation of the gene encoding mitochondrial transcription factor A, a master regulator of mitochondrial biogenesis. Consistent with known Smad3 function, reduced fibrotic tissue formation was also seen in regenerated Smad3-null muscle. In conclusion, Smad3 deficiency leads to impaired muscle regeneration, which underscores an essential role of Smad3 in postnatal myogenesis. Given the negative role of myostatin during muscle regeneration, the increased expression of myostatin observed in Smad3-null muscle may contribute to the regeneration defects.

A dilution cost approach to financial intermediation and securities markets

This paper proposes a model of financial markets and corporate finance,with asymmetric information and no taxes, where equity issues, Bankdebt and Bond financing may all co-exist in equilibrium. The paperemphasizes the relationship Banking aspect of financial intermediation:firms turn to banks as a source of investment mainly because banks aregood at helping them through times of financial distress. The debtrestructuring service that banks may offer, however, is costly. Therefore,the firms which do not expect to be financially distressed prefer toobtain a cheaper market source of funding through bond or equity issues.This explains why bank lending and bond financing may co-exist inequilibrium. The reason why firms or banks also issue equity in our modelis simply to avoid bankruptcy. Banks have the additional motive that theyneed to satisfy minimum capital adequacy requeriments. Several types ofequilibria are possible, one of which has all the main characteristics ofa "credit crunch". This multiplicity implies that the channels of monetarypolicy may depend on the type of equilibrium that prevails, leadingsometimes to support a "credit view" and other times the classical "moneyview".

GLUT8 is dispensable for embryonic development but influences hippocampal neurogenesis and heart function.

GLUT8 is a glucose transporter isoform expressed at high levels in testis; at intermediate levels in the brain, including the hippocampus; and at lower levels in the heart and several other tissues. GLUT8 is located in an intracellular compartment and does not appear to translocate to the cell surface, except in blastocysts, where insulin has been reported to induce its surface expression. Here, we generated mice with inactivation of the glut8 gene. We showed that expression of GLUT8 was not required for normal embryonic development and that glut8-/- mice had normal postnatal development, glucose homeostasis, and response to mild stress. Adult glut8-/- mice showed increased proliferation of hippocampal cells but no defect in memory acquisition and retention. Absence of GLUT8 from the heart did not alter heart size and morphology but led to an increase in P-wave duration, which was not associated with abnormal Nav1.5 Na+ channel or connexin expression. Thus, absence of GLUT8 expression in the mouse caused complex but mild physiological alterations.

Relationship Between the Development of the Spinal Canal and the Etiopathogenesis of Lumbar Spinal Stenosis

INTRODUCTION: The presence of a pre-existing narrow spinal canal may have an important place in the ethiopathogenesis of lumbar spinal stenosis. By consequence the study of the development of the spinal canal is crucial. The first goal of this work is to do a comprehensive literature search and to give an essential view on the development of spinal canal and its depending factors studied until now. The second goal is to give some considerations and hypothesize new leads for clinically useful researches. MATERIALS AND METHODS: A bibliographical research was executed using different search engines: PubMed, Google Schoolar ©, Ovid ® and Web Of Science ©. Free sources and avaible from the University of Lausanne (UNIL) and Centre Hospitalier Universitaire Vaudois (CHUV) were used. At the end of the bibliographic researches 114 references were found, 85 were free access and just 41 were cited in this work. Most of the found references are in English or in French. RESULTS AND DISCUSSION: The spinal canal is principally limited by the vertebrae which have a mesodermal origin. The nervous (ectodermal) tissue significantly influences the growth of the canal. The most important structure participating in the spinal canal growth is the neurocentral synchondrosis in almost the entire vertebral column. The fusion of the half posterior arches seems to have less importance for the canal size. The growth is not homogeneous but, depends on the vertebral level. Timing, rate and growth potentials differ by regions. Especially in the case of the lumbar segment, there is a craniocaudal tendency which entails a greater post-natal catch-up growth for distal vertebrae. Trefoil-shape of the L5 canal is the consequence of a sagittal growth deficiency. The spinal canal shares some developmental characteristics with different structures and systems, especially with the central nervous system. It may be the consequence of the embryological origin. It is supposed that not all the related structures would be affected by a growth impairment because of the different catch-up potentials. Studies found that narrower spinal canals might be related with cardiovascular and gastrointestinal symptoms, lower thymic function, bone mineral content, dental hypoplasia and Harris' lines. Anthropometric correlations found at birth disappear during the pediatric age. All factors which can affect bone and nervous growth might be relevant. Genetic predispositions are the only factors that can never be changed but the real impact is to ascertain. During the antenatal period, all the elements determining a good supply of blood and oxygen may influence the vertebral canal development, for example smoking during pregnancy. Diet is a crucial factor having an impact on both antenatal and postnatal growth. Proteins intake is the only proved dietetic relationship found in the bibliographic research of this work. The mechanical effects due to locomotion changes are unknown. Socioeconomic situation has an impact on several influencing factors and it is difficult to study it owing to numerous bias. CONCLUSIONS: A correct growth of spinal canal is evidently relevant to prevent not-degenerative stenotic conditions. But a "congenital" narrower canal may aggravate degenerative stenosis. This concerns specific groups of patient. If the size of the canal is highly involved in the pathogenesis of common back pains, a hypothetical measure to prevent developmental impairments could have a not- negligible impact on the society. It would be interesting to study more about dietetic necessities for a good spinal canal development. Understanding the relationship between nervous tissues and vertebra it might be useful in identifying what is needed for the ideal development. Genetic importance and the post-natal influences of upright standing on the canal growth remain unsolved questions. All these tracks may have a double purpose: knowing if it is possible to decrease the incidence of narrower spinal canal and consequently finding possible preventive measures. The development of vertebral canal is a complex subject which ranges over a wide variety of fields. The knowledge of this subject is an indispensable tool to understand and hypothesize the influencing factors that might lead to stenotic conditions. Unfortunately, a lack of information makes difficult to have a complete and satisfactory interdisciplinary vision.

Changes in ubiquitin immunoreactivity in developing rat brain: a putative role for ubiquitin and ubiquitin conjugates in dendrite outgrowth and differentiation.

The role of ubiquitin in development of the mammalian brain has been studied using a monoclonal antibody, RHUb1, specific for ubiquitin. Immunodevelopment of western blots of homogenate samples of the cerebral cortex, hippocampus and cerebellum prepared from animals of known postnatal age show marked developmental changes in conjugate level. Striking decreases in the level of a prominent conjugate of molecular weight 22,000, which is identified as ubiquitinated histone, are observed during the first postnatal week in the cerebral cortex and hippocampus, but not the cerebellum. A marked overall developmental decrease in the level of high-molecular-weight (> 40,000) ubiquitin conjugates which occurs predominantly during the third, but also the fourth, postnatal week is observed in all three regions. Immunocytochemical data obtained with the RHUb1 antibody show intense staining of neuronal perikarya, nuclei and dendrites in early postnatal cerebral cortex and hippocampus. Staining of pyramidal cell perikarya and dendrites is particularly prominent. The intensity of dendritic staining, particularly for the cerebral cortex, shows a striking decrease after postnatal day 14 and only faint dendritic staining is observed in the adult. In early postnatal cerebellum, immunoreactivity is predominantly nuclear, though some staining of the proximal regions of Purkinje cell dendrites is observed between postnatal days 4 and 19. As with the cerebral cortex and hippocampus, most of the ubiquitin reactivity is lost in adult animals. The loss of dendritic staining, particularly in the cerebral cortex, correlates with the decrease in the level of high-molecular-weight ubiquitin conjugates observed on the western blots. Immunodevelopment of western blots of a range of subcellular fractions prepared from developing rat forebrain shows that the developmental decrease in the level of high-molecular-weight ubiquitin conjugates is not uniform for all fractions. The decrease in conjugate level is most marked for the cell-soluble, mitochondrial and detergent-insoluble cytoskeletal fractions. Taken overall, the data suggest a role for ubiquitin in dendrite outgrowth and arborization, loss of dendritic ubiquitin immunoreactivity correlating with completion of these processes.
