Nutrigenomics and nutrigenetics: the emerging faces of nutrition.

The recognition that nutrients have the ability to interact and modulate molecular mechanisms underlying an organism's physiological functions has prompted a revolution in the field of nutrition. Performing population-scaled epidemiological studies in the absence of genetic knowledge may result in erroneous scientific conclusions and misinformed nutritional recommendations. To circumvent such issues and more comprehensively probe the relationship between genes and diet, the field of nutrition has begun to capitalize on both the technologies and supporting analytical software brought forth in the post-genomic era. The creation of nutrigenomics and nutrigenetics, two fields with distinct approaches to elucidate the interaction between diet and genes but with a common ultimate goal to optimize health through the personalization of diet, provide powerful approaches to unravel the complex relationship between nutritional molecules, genetic polymorphisms, and the biological system as a whole. Reluctance to embrace these new fields exists primarily due to the fear that producing overwhelming quantities of biological data within the confines of a single study will submerge the original query; however, the current review aims to position nutrigenomics and nutrigenetics as the emerging faces of nutrition that, when considered with more classical approaches, will provide the necessary stepping stones to achieve the ambitious goal of optimizing an individual's health via nutritional intervention.

La atenuación en artículos de revisión odontológicos en español: estudio exploratorio

Describimos el uso de estrategias de atenuación en 40 artículos de revisión (AR), publicados en español en revistas iberoamericanas entre 1994 y 2004. Identificamos las estrategias empleadas en las secciones retóricas por medio de un análisis contextual de género y clasificamos los atenuantes en cinco categorías: construcciones impersonales, deícticos temporales, aproximadores, escudos y atenuantes compuestos. Los resultados muestran que hay abundantes y variadas estrategias de atenuación en las tres secciones retóricas del AR, aunque son más frecuentes en el desarrollo y en la introducción. Predomina el modal epistémico “poder”, los adverbios y los adjetivos de posibilidad y probabilidad, y los verbos epistémicos. Registramos varias construcciones impersonales empleadas para atenuar. Los aproximadores se usan para expresar honestidad y varios niveles de certidumbre en las proposiciones; los deícticos temporales, para expresar provisionalidad y sugerir varias interpretaciones. Concluimos que la atenuación puede estar relacionada con la posición de los autores en la comunidad científica y con las características del AR como género discursivo. Asimismo, el nivel de expectativa en la escritura de este género podría condicionar cómo se presentan las proposiciones.

La douleur prolongée chez le nouveau-né: étude de cas [Prolonged pain in neonates: retrospective analysis].

INTRODUCTION: infants hospitalised in neonatology are inevitably exposed to pain repeatedly. Premature infants are particularly vulnerable, because they are hypersensitive to pain and demonstrate diminished behavioural responses to pain. They are therefore at risk of developing short and long-term complications if pain remains untreated. CONTEXT: compared to acute pain, there is limited evidence in the literature on prolonged pain in infants. However, the prevalence is reported between 20 and 40 %. OBJECTIVE : this single case study aimed to identify the bio-contextual characteristics of neonates who experienced prolonged pain. METHODS : this study was carried out in the neonatal unit of a tertiary referral centre in Western Switzerland. A retrospective data analysis of seven infants' profile, who experienced prolonged pain ,was performed using five different data sources. RESULTS : the mean gestational age of the seven infants was 32weeks. The main diagnosis included prematurity and respiratory distress syndrome. The total observations (N=55) showed that the participants had in average 21.8 (SD 6.9) painful procedures that were estimated to be of moderate to severe intensity each day. Out of the 164 recorded pain scores (2.9 pain assessment/day/infant), 14.6 % confirmed acute pain. Out of those experiencing acute pain, analgesia was given in 16.6 % of them and 79.1 % received no analgesia. CONCLUSION: this study highlighted the difficulty in managing pain in neonates who are exposed to numerous painful procedures. Pain in this population remains underevaluated and as a result undertreated.Results of this study showed that nursing documentation related to pain assessment is not systematic.Regular assessment and documentation of acute and prolonged pain are recommended. This could be achieved with clear guidelines on the Assessment Intervention Reassessment (AIR) cyclewith validated measures adapted to neonates. The adequacy of pain assessment is a pre-requisite for appropriate pain relief in neonates.

Iowa Prescription Monitoring Program, January 13, 2103

The Iowa Prescription Monitoring Program (PMP) provides authorized prescribers and pharmacists with information regarding their patients’ use of controlled substances and is used as a tool in determining appropriate prescribing and treatment of patients without fear of contributing to a patient’s abuse of or dependence on addictive drugs or diversion of those drugs to illicit use. Iowa pharmacies are required to report to the Iowa PMP all Schedule II, III, and IV controlled substances dispensed by the pharmacy to ambulatory patients.

Prise de poids et contraceptifs à progestatifs seuls: plus d'inquiétude que de preuves scientifiques. [Weight gain and progestin-only contraceptives: more concern than evidence].

Weight gain is a side effect often associated with progestin-only contraceptives. A recently published Cochrane review focuses on this issue that has been addressed in only few studies of good quality. Here we discuss the results of this review in the context of three clinical cases. With progestin-only contraceptives the weight gain is less than often thought, especially after six or twelve months of treatment. Some results are rather reassuring, especially those in obese women and during the post-partum period. This should help improve the compliance of women who fear gaining weight with this type of hormonal contraception.

Ebola Information for West Africans Living in the United States, November 14, 2014

West Africans in the United States may face negative responses from people in their community because of the current Ebola outbreak. People may say bad things about you, or try to stop you or your family from everyday activities like work, school, shopping, or spending time with friends. This is known as stigma. Stigma mostly occurs because of fear—people fear Ebola and the disease is linked with a specific region of the world. You are not more at risk for Ebola because of your specific race or country of origin.

Long-term changes in synaptic transmission of the lateral amygdala induced by strong "in vitro" activation

Résumé : L'amygdale latérale (AL) joue un .rôle essentiel dans la plasticité synaptique à la base du conditionnement de la peur. Malgré le faite que la majorité des cellules de l'AL reçoivent les afférentes nécessaires, une potentialisation dans seulement une partie d'entre elles est obligatoire afin que l'apprentissage de la peur ait lieu. Il a été montré que ces cellules expriment la forme active de CREB, et celui-ci a été associé aux cellules dites de type 'nonaccomrnodating' (nAC). Très récemment, une étude a impliqué les circuits récurrents de l'AL dans le conditionnement de la peur. Un lien entre ces deux observations n'a toutefois jamais été établi. t Nous avons utilisé un protocole in vitro de forte activation de l'AL, résultant dans l'induction de 'bursts' provenant de l'hippocampe et se propageant jusqu'à l'AL. Dans l'AL ces 'bursts' atteignent toutes les cellules et se propagent à travers plusieurs chemins. Utilisant ce protocole, nous avons, pour la première fois pu associer dans l'AL, des cellules connectées de manière récurrente avec des cellules de type nAC. Aussi bien dans ces dernières que dans les cellules de type 'accommodating' (AC), une diminution dans la transmission inhibitrice, à la fois exprimée de manière pré synaptique mais également indépendant de la synthèse de protéine a pu être observé. Au contraire, une potentialisation induite et exprimée au niveau pré synaptique ainsi que dépendante de la synthèse de protéine a pu être trouvé uniquement dans les cellules de type nAC. De plus, une hyperexcitabilité, dépendante des récepteurs NMDA a pu être observé, avec une sélection préférentielle des cellules du type nAC dans la génération de bursts. Nous avons également pu démontrer que la transformation d'un certain nombre de cellules de type AC en cellules dites nAC accompagnait cette augmentation générale de l'excitabilité de l'AL. Du faite da la grande quantité d'indices suggérant une connexion entre le système noradrénergique et les états de peur/d'anxiété, les effets d'une forte activation de l'AL sur ce dernier ont été investigués et ont révélés une perte de sa capacité de modulation du 'spiking pattern'. Finalement, des changements au niveau de l'expression d'un certain nombre de gènes, incluant celui codant pour le BDNF, a pu être trouvé à la suite d'une forte activation de l'AL. En raison du lien récemment décrit entre l'expression de la forme active de CREB et des cellules de type nAC ainsi que celui de l'implication des cellules de l'AL connectés de manière récurrente dans l'apprentissage de la peur, nos résultats nous permettent de suggérer un modèle expliquant comment la potentialisation des connections récurrentes entre cellules de type nAC pourrait être à la base de leur recrutement sélectif pendant le conditionnement de la peur. De plus, ils peuvent offrir des indices par rapport aux mécanismes à travers lesquels une sous population de neurones peut être réactivée par une stimulation externe précédemment inefficace, et induire ainsi un signal suffisamment fort pour qu'il soit transmit aux structures efférentes de l'AL. Abstract : The lateral nucleus of the amygdala (LA) is critically involved in the plasticity underlying fear-conditioned learning (Sah et al., 2008). Even though the majority of cells in the LA receive the necessary sensory inputs, potentiation in only a subset is required for fear learning to occur (Repa et al., 2001; Rumpel et al., 2005). These cells express active CREB (CAMP-responsive element-binding protein) (Han et al., 200, and this was related to the non-accommodating (nAC) spiking phenotype (Viosca et al., 2009; Zhou et al., 2009). In addition, a very recent study implicated recurrently connected cells of the LA in fear conditioned learning (Johnson et al., 2008). A link between the two observations has however never been made. In rats, we used an in vitro protocol of strong activation of the LA, resulting in bursting activity, which spread from the hippocampus to the LA. Within the LA, this activity reached all cells and spread via a multitude of pathways. Using this model, we were able to link, for the first time, recurrently connected cells in the LA with cells of the nAC phenotype. While we found a presynaptically expressed, protein synthesis independent decrease in inhibitory synaptic transmission in both nAC and accommodating (AC) cells, only nAC cells underwent a presynaptically induced and expressed, protein synthesis dependent potentiation. Moreover we observed an NMDA dependent hyperexcitability of the LA, with a preferential selection of nAC cells into burst generation. The transformation of a subset of AC cells into nAC cells accompanied this general increase in LA excitability. Given the considerable evidence suggesting a relationship between the central noradrenergic (NA) system and fear/anxiety states (Itoi, 2008), the effects of strong activation of the LA on the noradrenergic system were investigated, which revealed a loss of its modulatory actions on cell spiking patterns. Finally, we found changes in the expression levels of a number of genes; among which the one coding for $DNF, to be induced by strong activation of the LA. In view of the recently described link between nAC cells and expression of pCREB (phosphorylated cAMP-responsive element-binding protein) as well as the involvement of recurrently connected cells of the LA in fear-conditioned learning, our findings may provide a model of how potentiation of recurrent connections between nAC neurons underlies their recruitment into the fear memory trace. Additionally, they may offer clues as to the mechanisms through which a selected subset of neurons can be reactivated by smaller, previously ineffective external stimulations to respond with a sufficiently strong signal, which can be transmitted to downstream targets of the LA.

Children's experience regarding the quality of their hospital stay: the development of an assessment questionnaire for children

A questionnaire assessing the satisfaction of children with their hospital stay has been developed and tested with 136 children (aged 6-12 years) at 2 Swiss hospital sites. Three out of 4 children were satisfied overall with their hospital stay. Their relationships with the professional medical staff, explanations they received, games they played, and environment, all received positive evaluations. The most critical points were pain, fear, and the absence of relatives. Ninety percent of the children appreciated that their opinions were sought. These results reinforce the importance of having questionnaires available for the children to consider their opinions to enhance the quality of care.

Life designing: A paradigm for career construction in the 21st century

At the beginning of the 21st century, a new social arrangement of work poses a series of questions and challenges to scholars who aim to help people develop their working lives. Given the globalization of career counseling, we decided to address these issues and then to formulate potentially innovative responses in an international forum. We used this approach to avoid the difficulties of creating models and methods in one country and then trying to export them to other countries where they would be adapted for use. This article presents the initial outcome of this collaboration, a counseling model and methods. The life-designing model for career intervention endorses five presuppositions about people and their work lives: contextual possibilities, dynamic processes, non-linear progression, multiple perspectives, and personal patterns. Thinking from these five presuppositions, we have crafted a contextualized model based on the epistemology of social constructionism, particularly recognizing that an individual's knowledge and identity are the product of social interaction and that meaning is co-constructed through discourse. The life-design framework for counseling implements the theories of self-constructing [Guichard, J. (2005). Life-long self-construction. International Journal for Educational and Vocational Guidance, 5, 111-124] and career construction [Savickas, M. L. (2005). The theory and practice of career construction. In S. D. Brown & R. W. Lent (Eds.), Career development and counselling: putting theory and research to work (pp. 42-70). Hoboken, NJ: Wiley] that describe vocational behavior and its development. Thus, the framework is structured to be life-long, holistic, contextual, and preventive.

Residents' Rights

Resident rights are guaranteed by the federal Nursing Home Reform Law of 1987, which requires nursing facilities to promote and protect the rights of each resident and places a strong emphasis on individual dignity and self-determination. Residents’ rights include, but are not limited to: • Being treated with respect and dignity • Being free from abuse and chemical and physical restraints • Participating in one’s own care and treatment • Being ensured information is being kept confidential • Managing one’s own finances • Being free to voice grievances, without fear of retaliation • Being able to associate and communicate privately with any person • Being able to send and receive personal mail • Making independent choices • Being able to apply for state and federal assistance without discrimination • Being informed of rights, services available and all charges prior to admission • Being given advance notice of a transfer or discharge

Causes and implications of overdiagnosis

Background: Overdiagnosis is defined as the diagnosis of a condition not associated with a substantial risk for health in an asymptomatic person. There are several causes of overdiagnosis. Clinical and public health implications of overdiagnosis are underappreciated. Objective: To review the causes of overdiagnosis, and its clinical and public health implications Method: Narrative review Results: Overdiagnosis results from some screening activities, increasingly sensitive diagnostic test procedures, incidental findings on routine exams, and widening diagnostic criteria to define a condition requiring an intervention. The fear of missing a diagnosis and the patients' requests for reassurance are further causes of overdiagnosis. Examples of overdiagnosis include some cases of breast and prostate cancers found by screening, pulmonary emboli identified on highly sensitive CT-scans, and kidney cancers found incidentally following abdominal CTscans. Lowering the critical levels of blood pressure, glycemia, and cholesterol to define hypertension, diabetes, and hypercholesterolemia, respectively, is also the causes of overdiagnosis. An overdiagnosed condition implies unnecessary procedures to confirm or exclude the presence of the disease and unnecessary treatments, both having potential adverse effects. Overdiagnosis also diverts health professionals from caring about other health issues and generates costs without any benefit. Measures to prevent overdiagnosis are notably 1) to increase awareness of health professionals and the population about its occurrence, 2) to account systematically for the risks and benefits of screening and diagnostic procedures using an evidence-based framework, and 3) to decide at which risk level to intervene based on the absolute risk of health events and the absolute risk reduction expected from an intervention. Conclusion: Overdiagnosis has major clinical and public health implications. Increasing awareness of its causes and implications is a step toward its prevention.

Mothers' experience of their contact with their stillborn infant: an interpretative phenomenological analysis.

BACKGROUND: Guidelines surrounding maternal contact with the stillborn infant have been contradictory over the past thirty years. Most studies have reported that seeing and holding the stillborn baby is associated with fewer anxiety and depressive symptoms among mothers of stillborn babies than not doing so. In contrast, others studies suggest that contact with the stillborn infant can lead to poorer maternal mental health outcomes. There is a lack of research focusing on the maternal experience of this contact. The present study aimed to investigate how mothers describe their experience of spending time with their stillborn baby and how they felt retrospectively about the decision they made to see and hold their baby or not. METHOD: In depth interviews were conducted with twenty-one mothers three months after stillbirth. All mothers had decided to see and the majority to hold their baby. Qualitative analysis of the interview data was performed using Interpretive Phenomenological Analysis. RESULTS: Six superordinate themes were identified: Characteristics of Contact, Physicality; Emotional Experience; Surreal Experience; Finality; and Decision. Having contact with their stillborn infant provided mothers with time to process what had happened, to build memories, and to 'say goodbye', often sharing the experience with partners and other family members. The majority of mothers felt satisfied with their decision to spend time with their stillborn baby. Several mothers talked about their fear of seeing a damaged or dead body. Some mothers experienced strong disbelief and dissociation during the contact. CONCLUSIONS: Results indicate that preparation before contact with the baby, professional support during the contact, and professional follow-up are crucial in order to prevent the development of maternal mental health problems. Fears of seeing a damaged or dead body should be sensitively explored and ways of coping discussed. Even in cases where mothers experienced intense distress during the contact with their stillborn baby, they still described that having had this contact was important and that they had taken the right decision. This indicates a need for giving parents an informed choice by engaging in discussions about the possible benefits and risks of seeing their stillborn baby.
