New York City: "gilt cage" or "promised land" ? : representations of urban space in Edith Wharton and Anzia Yezierska

This thesis explores the importance of literary New York City in the urban narratives of Edith Wharton and Anzia Yezierska. It specifically looks at the Empire City of the Progressive Period when the concept of the city was not only a new theme but also very much a typical American one which was as central to the American experience as had been the Western frontier. It could be argued, in fact, that the American city had become the new frontier where modern experiences like urbanization, industrialization, immigration, and also women's emancipation and suffrage, caused all kinds of sensations on the human scale from smoothly lived assimilation and acculturation to deeply felt alienation because of the constantly shifting urban landscape. The developing urban space made possible the emergence of new female literary protagonists like the working girl, the reformer, the prostitute, and the upper class lady dedicating her life to 'conspicuous consumption'. Industrialization opened up city space to female exploration: on the one hand, upper and middle class ladies ventured out of the home because of the many novel urban possibilities, and on the other, lower class and immigrant girls also left their domestic sphere to look for paid jobs outside the home. New York City at the time was not only considered the epicenter of the world at large, it was also a city of great extremes. Everything was constantly in flux: small brownstones made way for ever taller skyscrapers and huge waves of immigrants from Europe pushed native New Yorkers further uptown on the island, adding to the crowdedness and intensity of the urban experience. The city became a polarized urban space with Fifth Avenue representing one end of the spectrum and the Lower East Side the other. Questions of space and the urban home greatly mattered. It has been pointed out that the city setting functions as an ideal means for the display of human nature as well as social processes. Narrative representations of urban space, therefore, provide a similar canvas for a protagonist's journey and development. From widely diverging vantage points both Edith Wharton and Anzia Yezierska thus create a polarized city where domesticity is a primal concern. Looking at all of their New York narratives by close readings of exterior and interior city representations, this thesis shows how urban space greatly affects questions of identity, assimilation, and alienation in literary protagonists who cannot escape the influence of their respective urban settings. Edith Wharton's upper class "millionaire" heroines are framed and contained by the city interiors of "old" New York, making it impossible for them to truly participate in the urban landscape in order to develop outside of their 'Gilt Cages'. On the other side are Anzia Yezierska's struggling "immigrant" protagonists who, against all odds, never give up in their urban context of streets, rooftops, and stoops. Their New York City, while always challenging and perpetually changing, at least allows them perspectives of hope for a 'Promised Land' in the making. Central for both urban narrative approaches is the quest for a home as an architectural structure, a spiritual resting place, and a locus for identity forming. But just as the actual city embraces change, urban protagonists must embrace change also if they desire to find fulfillment and success. That this turns out to be much easier for Anzia Yezierska's driven immigrants rather than for Edith Wharton's well established native New Yorkers is a surprising conclusion to this urban theme.

Contextual Effects on Hopelessness in the Second Half of the Life

Depression and suicidal ideation are tightly linked to the lack of hope in the future. Hopelessness begins with the occurrence of negative life events and develops through the perception that negative outcomes are stable and pervasive. Most of the research has investigated individual factors predicting hopelessness. However, other studies have shown that the social context may also play an important role: disadvantaged contexts exacerbate the feeling that future is unreachable and hopeless. In this study we investigate the role of shared emotions (emotional climates) on the sense of hopelessness during the second half of the life. Emotional climates have been defined as the emotional relationships constructed between members of a society and describe the quality of the environment within a particular community. We present results of multilevel analyses using data from the NCCR-LIVES769 project «Vulnerability and growth», the Swiss Household Panel and official statistics, that explore the relationship between characteristics of the Swiss cantons and hopelessness. Although hopelessness is mainly affected by individual factors as life events and personality, results show that canton socio-economic conditions and climates of optimism or pessimism have an effect on the individual perception of hopelessness. Individuals are more likely to feel hopeless after having experienced critical events (i.e., loss of the partner in the late life) in cantons with high rates of unemployment and with a high share of negative emotions. On the contrary, positive emotional climates play a protective role against hopelessness.

Le suicidant, sa famille et son médecin

Résumé : Le suicidant, sa famille et son médecin. - Dans une lignée systémique, nous avons à nous demander quelle représentation du suicide ont les suicidants par rapport à l'acte lui-même et par rapport à l'impact que ces mêmes actes ont sur leur famille. D'autre part, il convient de nous interroger sur les représentations que chaque membre de la famille peut construire de l'acte suicidaire lui-même, du sens qu'il revêt pour le jeune et les proches. Notre expérience de psychiatres dans un hôpital général nous amène à nous questionner aussi sur les représentations de cet acte chez les professionnels qui offrent des soins aigus somatiques et qui luttent pour la vie lorsque les patients eux ont opté pour la mort. Ce geste nous envoie un signal fort de perte d'espoir et d'absence de perspectives futures chez les suicidants. Il nous renvoie aussi à la question de la mort chez les médecins formés à lutter pour la vie. L'acte suicidaire est un geste violent qui renvoie aux soignants un sentiment d'impuissance et pour lequel ils se sentent démunis. Nous aborderons dans une première partie l'attitude adoptée dans le service de psychiatrie de liaison à Lausanne. Nous exposerons ensuite quelques pistes de réflexion sur la prise en charge des suicidants dans un effort de compréhension systémique. Une responsabilité majeure éthique et humaine nous incombe.Summary : The suicidal person, his family and his doctor. - In a systemic lineage, we have to ask ourselves what representation of suicide do people with suicidal tendencies have, and what is the impact of suicide on their families and their doctor. On the other hand, it is advisable to ask ourselves what does suicide mean to their relatives. Our practice as psychiatrists in a general hospital leads us also to try and understand the image and impact of suicide on the medical staff who constantly aims at saving lives, while patients opted for death. This act sends us a strong signal of loss of hope and the absence of prospects for suicidal people. It has also a strong emotional impact on health practitioners and frequently makes them feel helpless. It also sends back to us to the question of the image of death among doctors. We will discuss, in a first part, the adopted attitude in the service of liaison psychiatry in Lausanne. We will try and develop then a way of taking care of suicidal patients, their families and the medical staff, attending them in a systemic approach. This is a great ethical and human responsibility to all health practitioners.

Managing Social-Business Tensions: A Review and Research Agenda for Social Enterprise

In a world filled with poverty, environmental degradation, and moral injustice, social enterprises offer a ray of hope. These organizations seek to achieve social missions through business ventures. Yet social missions and business ventures are associated with divergent goals, values, norms, and identities. Attending to them simultaneously creates tensions, competing demands, and ethical dilemmas. Effectively understanding social enterprises therefore depends on insight into the nature and management of these tensions. While existing research recognizes tensions between social missions and business ventures, we lack any systematic analysis. Our paper addresses this issue. We first categorize the types of tensions that arise between social missions and business ventures, emphasizing their prevalence and variety. We then explore how four different organizational theories offer insight into these tensions, and we develop an agenda for future research. We end by arguing that a focus on social-business tensions not only expands insight into social enterprises, but also provides an opportunity for research on social enterprises to inform traditional organizational theories. Taken together, our analysis of tensions in social enterprises integrates and seeks to energize research on this expanding phenomenon.

Novel testis germ cell-specific transcript of the CREB gene contains an alternatively spliced exon with multiple in-frame stop codons.

The gene encoding the cAMP-responsive transcription factor CREB consists of multiple small exons some of which undergo alternative RNA splicing. We describe the finding of a novel transcript of the CREB gene expressed at high levels in the germ cells of the rat testis. The transcript contains an alternatively spliced exon inserted within the sequence encoding the transcriptional transactivation domain of CREB and this exon contains multiple in-frame stop codons. Furthermore, the exon is conserved in both rat and human genes (75% nucleotide identity). Although the function(s) of this RNA or the truncated CREB protein predicted to result from the translation of this unusual transcript is unknown, the high level of expression in the testicular germ cells and remarkable conservation of sequences in rat and human suggests that it may have a unique biological function in these cells.

GENETIC AND BIOCHEMICAL ANALYSIS OF THE TESTIS-SPECIFIC ZINC FINGER PROTEIN CTCFL/BORIS

Abstract en FrançaisCTCFL a d'abord été identifié comme un paralogue de la protéine ubiquitaire CTCF en raison de sa forte homologie entre leurs onze « zinc fingers », un domaine de liaison à l'ADN. Parmi ses nombreux rôles, la liaison des zinc fingers de CTCF à la région de contrôle de l'empreinte (ICR) maternelle non-méthylée Igf2/H19, contrôle l'expression empreinte (monoallélique) de H19 et IGF2 dans les cellules somatiques. La méthylation de l'ICR Igf2/H19 paternelle est nécessaire à l'expression empreinte de ces deux gènes. Bien que le mécanisme par lequel l'ICR est méthylé soit mal compris, il est connu que l'établissement de la méthylation se produit pendant le développement des cellules germinales mâles et que les ADN méthyltransférases de novo DNMT3A et DNMT3L sont essentiels. Par conséquent, CTCFL fournit un bon candidat pour un rôle dans la méthylation de l'ICR paternelle Igf2/H19 en raison de son expression restreinte à certains types de cellules où la méthylation de l'ICR a lieu (spermatogonies et spermatocytes) ainsi qu'en raison sa capacité à lier les ICR lgf2/HÎ9 dans ces cellules. Les premiers travaux expérimentaux de cette thèse portent sur le rôle possible des mutations de CTCFL chez les patients atteints du syndrome de Silver-Russell (SRS), où une diminution de la méthylation de l'ICR IGF2/H19 a été observée chez 60% d'entre eux. Admettant que CTCFL pourrait être muté chez ces patients, j'ai examiné les mutations possibles de CTCFL chez 35 d'entre eux par séquençage de l'ADN et analyse du nombre de copies d'exons. N'ayant trouvé aucune mutation chez ces patients, cela suggère que les mutations de CTCFL ne sont pas associées au SRS. Les travaux expérimentaux suivants ont porté sur les modifications post-traductionnelles de CTCFL par la protéine SU MO « small ubiquitin-like modifier » (SUMO). La modification de protéines par SU MO change les interactions avec d'autres molécules (ADN ou protéines). Comme CTCFL régule sans doute l'expression d'un certain nombre de gènes dans le cancer et que plusieurs facteurs de transcription sont régulés par SUMO, j'ai mené des expériences pour déterminer si CTCFL est sumoylé. En effet, j'ai observé que CTCFL est sumoylated in vitro et in vivo et j'ai déterminé les deux résidus d'attachement de SUMO aux lysines 181 et 645. Utilisant les mutants de CTCFL K181R et K645R ne pouvant pas être sumoylated, j'ai évalué les conséquences fonctionnelles de la modification par SUMO. Je n'ai trouvé aucun changement significatif dans la localisation subcellulaire, la demi-vie ou la liaison à l'ADN, mais ai constaté que la sumoylation module à la fois {'activation CTCFL-dépendante et la répression de l'expression génique. Il s'agit de la première modification post-traductionnelle décrite pour CTCFL et les conséquences possibles de cette modification sont discutées pour le cancer et les testicules normaux. Avec cette thèse, j'espère avoir ajouté des résultats importants à l'étude de CTCFL et donné quelques idées pour de futures recherches.AbstractJeremiah Bernier-Latmani, Institute of Pathology, University of Lausanne, CHUVCTCFL was first identified as a paralog of the ubiquitous protein CTCF because of high homology between their respective eleven zinc fingers, a DNA binding domain. Among its many roles, CTCF zinc finger-mediated binding to the unmethylated maternal Igf2/H19 imprinting control region (ICR), controls the imprinted (monoallelic) expression of Igf2 and H19 in somatic cells. Methylation of the paternal Igf2/H19 ICR is necessary for the imprinted expression of the two genes. Although the mechanism by which the ICR is methylated is incompletely understood, it is known that establishment of methylation occurs during male germ cell development and the de novo DNA methyltransferases DNMT3A and DNMT3L are essential. Therefore, CTCFL provided a good candidate to play a role in methylation of the paternal Igf2/H19 ICR because of its restricted expression to cell types where ICR methylation takes place (spermatogonia and spermatocytes) and its ability to bind the Igf2/H19 ICR in these cells. The first experimental work of this thesis investigated the possible role of CTCFL mutations in Silver-Russell syndrome (SRS) patients, where it has been observed that 60% of the patients have reduced methylation of the IGF2/HÎ9 ICR. Reasoning that CTCFL could be mutated in these patients, I screened 35 patients for mutations in CTCFL by DNA sequencing and exon copy number analysis, I did not find any mutations in these patients suggesting that mutations of CTCFL are not associated with SRS. The next experimental work of my thesis focused on posttranslational modification of CTCFL by small ubiquitin-like modifier (SUMO) protein. SUMO modification of proteins changes the interactions with other molecules (DNA or protein). As CTCFL arguably regulates the expression of a number of genes in cancer and many transcription factors are regulated by SUMO, I conducted experiments to assess whether CTCFL is sumoylated. I found that CTCFL is sumoylated in vitro and in vivo and determined the two residues of SUMO attachment to be lysines 181 and 645. Using K181R, K645R mutated CTCFL- which cannot be detected to be sumoylated-1 assessed the functional consequences of SUMO modification. I found no significant changes in subcellular localization, half-life or DNA binding, but found that sumoylation modulates both CTCFL-dependent activation and repression of gene expression. This is the first posttranslational modification described for CTCFL and possible consequences of this modification are discussed in both cancer and normal testis. With this thesis, I hope I have added important findings to the study of CTCFL and provide some ideas for future research.

Wheat germ cell-free expression: Two detergents with a low critical micelle concentration allow for production of soluble HCV membrane proteins.

Membrane proteins are notoriously difficult to express in a soluble form. Here, we use wheat germ cell-free expression in the presence of various detergents to produce the non-structural membrane proteins 2, 4B and 5A of the hepatitis C virus (HCV). We show that lauryl maltose neopentyl glycol (MNG-3) and dodecyl octaethylene glycol ether (C12E8) detergents can yield essentially soluble membrane proteins at detergent concentrations that do not inhibit the cell-free reaction. This finding can be explained by the low critical micelle concentration (CMC) of these detergents, which keeps the monomer concentrations low while at the same time providing the necessary excess of detergent concentration above CMC required for full target protein solubilization. We estimate that a tenfold excess of detergent micelles with respect to the protein concentration is sufficient for solubilization, a number that we propose as a guideline for detergent screening assays.

Germ cell-specific targeting of DICER or DGCR8 reveals a novel role for endo-siRNAs in the progression of mammalian spermatogenesis and male fertility.

Small non-coding RNAs act as critical regulators of gene expression and are essential for male germ cell development and spermatogenesis. Previously, we showed that germ cell-specific inactivation of Dicer1, an endonuclease essential for the biogenesis of micro-RNAs (miRNAs) and endogenous small interfering RNAs (endo-siRNAs), led to complete male infertility due to alterations in meiotic progression, increased spermatocyte apoptosis and defects in the maturation of spermatozoa. To dissect the distinct physiological roles of miRNAs and endo-siRNAs in spermatogenesis, we compared the testicular phenotype of mice with Dicer1 or Dgcr8 depletion in male germ cells. Dgcr8 mutant mice, which have a defective miRNA pathway while retaining an intact endo-siRNA pathway, were also infertile and displayed similar defects, although less severe, to Dicer1 mutant mice. These included cumulative defects in meiotic and haploid phases of spermatogenesis, resulting in oligo-, terato-, and azoospermia. In addition, we found by RNA sequencing of purified spermatocytes that inactivation of Dicer1 and the resulting absence of miRNAs affected the fine tuning of protein-coding gene expression by increasing low level gene expression. Overall, these results emphasize the essential role of miRNAs in the progression of spermatogenesis, but also indicate a role for endo-siRNAs in this process.

Pituitary blastoma: a pathognomonic feature of germ-line DICER1 mutations.

Individuals harboring germ-line DICER1 mutations are predisposed to a rare cancer syndrome, the DICER1 Syndrome or pleuropulmonary blastoma-familial tumor and dysplasia syndrome [online Mendelian inheritance in man (OMIM) #601200]. In addition, specific somatic mutations in the DICER1 RNase III catalytic domain have been identified in several DICER1-associated tumor types. Pituitary blastoma (PitB) was identified as a distinct entity in 2008, and is a very rare, potentially lethal early childhood tumor of the pituitary gland. Since the discovery by our team of an inherited mutation in DICER1 in a child with PitB in 2011, we have identified 12 additional PitB cases. We aimed to determine the contribution of germ-line and somatic DICER1 mutations to PitB. We hypothesized that PitB is a pathognomonic feature of a germ-line DICER1 mutation and that each PitB will harbor a second somatic mutation in DICER1. Lymphocyte or saliva DNA samples ascertained from ten infants with PitB were screened and nine were found to harbor a heterozygous germ-line DICER1 mutation. We identified additional DICER1 mutations in nine of ten tested PitB tumor samples, eight of which were confirmed to be somatic in origin. Seven of these mutations occurred within the RNase IIIb catalytic domain, a domain essential to the generation of 5p miRNAs from the 5' arm of miRNA-precursors. Germ-line DICER1 mutations are a major contributor to PitB. Second somatic DICER1 "hits" occurring within the RNase IIIb domain also appear to be critical in PitB pathogenesis.

Fermeture percutanée de l'auricule gauche: un nouvel espoir pour le patient en fibrillation auriculaire [Percutaneous closure of left atrial appendage: a new hope for patients with atrial fibrillation?].

Atrial fibrillation (AF) is the most common cardiac arrhythmia. The risk of thromboembolic events is important, and at that time, there is no definite treatment for AF. Oral anticoagulation also represents a hemorrhagic risk factor. Ninety percent of atrial thrombi are located within the left atrial appendage. The percutaneous closure of this left atrial appendage with a device has been shown to decrease thromboembolic events even after interruption of oral anticoagulation as compared to warfarin in a recent randomized study. Recent data support this innovative technique as a reasonable alternative to long term anticoagulation in patients at high risk of bleeding.

Functional studies of a germ-line polymorphism at codon 47 within the p53 gene.

A rare germ-line polymorphism in codon 47 of the p53 gene replaces the wild-type proline (CCG) with a serine (TCG). Restriction analysis of 101 human samples revealed the frequency of the rare allele to be 0% (n = 69) in Caucasians and 4.7% (3/64, n = 32) among African-Americans. To investigate the consequence of this amino acid substitution, a cDNA construct (p53 mut47ser) containing the mutation was introduced into a lung adenocarcinoma cell line (Calu-6) that does not express p53. A growth suppression similar to that obtained after introduction of a wild-type p53 cDNA construct was observed, in contrast to the result obtained by introduction of p53 mut143ala. Furthermore, expression of neither p53 mut47ser nor wild-type p53 was tolerated by growing cells. In transient expression assays, both mut47ser and wild-type p53 activated the expression of a reporter gene linked to a p53 binding sequence (PG13-CAT) and inhibited the expression of the luciferase gene under the control of the Rous sarcoma virus promoter (RSVluc). In the same assay, mut143ala did not activate the expression of PG13-CAT and produced only a slight inhibitory effect on RSVluc. These findings indicate that the p53 variant with a serine at codon 47 should be considered as a rare germ-line polymorphism that does not alter the growth-suppression activity of p53.

Rapid evolution of cancer/testis genes on the X chromosome.

BACKGROUND: Cancer/testis (CT) genes are normally expressed only in germ cells, but can be activated in the cancer state. This unusual property, together with the finding that many CT proteins elicit an antigenic response in cancer patients, has established a role for this class of genes as targets in immunotherapy regimes. Many families of CT genes have been identified in the human genome, but their biological function for the most part remains unclear. While it has been shown that some CT genes are under diversifying selection, this question has not been addressed before for the class as a whole. RESULTS: To shed more light on this interesting group of genes, we exploited the generation of a draft chimpanzee (Pan troglodytes) genomic sequence to examine CT genes in an organism that is closely related to human, and generated a high-quality, manually curated set of human:chimpanzee CT gene alignments. We find that the chimpanzee genome contains homologues to most of the human CT families, and that the genes are located on the same chromosome and at a similar copy number to those in human. Comparison of putative human:chimpanzee orthologues indicates that CT genes located on chromosome X are diverging faster and are undergoing stronger diversifying selection than those on the autosomes or than a set of control genes on either chromosome X or autosomes. CONCLUSION: Given their high level of diversifying selection, we suggest that CT genes are primarily responsible for the observed rapid evolution of protein-coding genes on the X chromosome.

ESCMID* guideline for the diagnosis and management of Candida diseases 2012: developing European guidelines in clinical microbiology and infectious diseases.

The process to develop a guideline in a European setting remains a challenge. The ESCMID Fungal Infection Study Group (EFISG) successfully achieved this endeavour. After two face-to-face meetings, numerous telephone conferences, and email correspondence, an ESCMID task force (basically composed of members of the Society's Fungal Infection Study Group, EFISG) finalized the ESCMID diagnostic and management/therapeutic guideline for Candida diseases. By appreciating various patient populations at risk for Candida diseases, four subgroups were predefined, mainly ICU patients, paediatric, HIV/AIDS and patients with malignancies including haematopoietic stem cell transplantation. Besides treatment recommendations, the ESCMID guidelines provide guidance for diagnostic procedures. For the guidelines, questions were formulated to phrase the intention of a given recommendation, for example, outcome. The recommendation was the clinical intervention, which was graded by a score of A-D for the 'Strength of a recommendation'. The 'level of evidence' received a score of I-III. The author panel was approved by ESCMID, European Organisation for Research and Treatment of Cancer, European Group for Blood and Marrow Transplantation, European Society of Intensive Care Medicine and the European Confederation of Medical Mycology. The guidelines followed the framework of GRADE and Appraisal of Guidelines, Research, and Evaluation. The drafted guideline was presented at ECCMID 2011 and points of discussion occurring during that meeting were incorporated into the manuscripts. These ESCMID guidelines for the diagnosis and management of Candida diseases provide guidance for clinicians in their daily decision-making process.

Perinatal care at the limit of viability between 22 and 26 completed weeks of gestation in Switzerland.

Perinatal care of pregnant women at high risk for preterm delivery and of preterm infants born at the limit of viability (22-26 completed weeks of gestation) requires a multidisciplinary approach by an experienced perinatal team. Limited precision in the determination of both gestational age and foetal weight, as well as biological variability may significantly affect the course of action chosen in individual cases. The decisions that must be taken with the pregnant women and on behalf of the preterm infant in this context are complex and have far-reaching consequences. When counselling pregnant women and their partners, neonatologists and obstetricians should provide them with comprehensive information in a sensitive and supportive way to build a basis of trust. The decisions are developed in a continuing dialogue between all parties involved (physicians, midwives, nursing staff and parents) with the principal aim to find solutions that are in the infant's and pregnant woman's best interest. Knowledge of current gestational age-specific mortality and morbidity rates and how they are modified by prenatally known prognostic factors (estimated foetal weight, sex, exposure or nonexposure to antenatal corticosteroids, single or multiple births) as well as the application of accepted ethical principles form the basis for responsible decision-making. Communication between all parties involved plays a central role. The members of the interdisciplinary working group suggest that the care of preterm infants with a gestational age between 22 0/7 and 23 6/7 weeks should generally be limited to palliative care. Obstetric interventions for foetal indications such as Caesarean section delivery are usually not indicated. In selected cases, for example, after 23 weeks of pregnancy have been completed and several of the above mentioned prenatally known prognostic factors are favourable or well informed parents insist on the initiation of life-sustaining therapies, active obstetric interventions for foetal indications and provisional intensive care of the neonate may be reasonable. In preterm infants with a gestational age between 24 0/7 and 24 6/7 weeks, it can be difficult to determine whether the burden of obstetric interventions and neonatal intensive care is justified given the limited chances of success of such a therapy. In such cases, the individual constellation of prenatally known factors which impact on prognosis can be helpful in the decision making process with the parents. In preterm infants with a gestational age between 25 0/7 and 25 6/7 weeks, foetal surveillance, obstetric interventions for foetal indications and neonatal intensive care measures are generally indicated. However, if several prenatally known prognostic factors are unfavourable and the parents agree, primary non-intervention and neonatal palliative care can be considered. All pregnant women with threatening preterm delivery or premature rupture of membranes at the limit of viability must be transferred to a perinatal centre with a level III neonatal intensive care unit no later than 23 0/7 weeks of gestation, unless emergency delivery is indicated. An experienced neonatology team should be involved in all deliveries that take place after 23 0/7 weeks of gestation to help to decide together with the parents if the initiation of intensive care measures appears to be appropriate or if preference should be given to palliative care (i.e., primary non-intervention). In doubtful situations, it can be reasonable to initiate intensive care and to admit the preterm infant to a neonatal intensive care unit (i.e., provisional intensive care). The infant's clinical evolution and additional discussions with the parents will help to clarify whether the life-sustaining therapies should be continued or withdrawn. Life support is continued as long as there is reasonable hope for survival and the infant's burden of intensive care is acceptable. If, on the other hand, the health care team and the parents have to recognise that in the light of a very poor prognosis the burden of the currently used therapies has become disproportionate, intensive care measures are no longer justified and other aspects of care (e.g., relief of pain and suffering) are the new priorities (i.e., redirection of care). If a decision is made to withhold or withdraw life-sustaining therapies, the health care team should focus on comfort care for the dying infant and support for the parents.
