Effectiveness of a pediatric palliative home care team as experienced by parents and health care professionals.

OBJECTIVES: Little data are available on palliative home care for children. The objective of this study was to evaluate the effectiveness of a specialized pediatric palliative home care team (PPHCT) as experienced by parents and health care professionals (HCPs). METHODS: Parents and HCPs involved in the care of terminally ill children who died and whom the PPHCT was in charge of were surveyed with questionnaires focusing on satisfaction with the PPHCT, satisfaction with the course of the dying phase, and the development of anxiety, depression, and prolonged grief disorder. RESULTS: Forty-three parent dyads participated (return rate, 88%). Satisfaction with the PPHCT scored a median of 10 (numeric rating scale, 0-10). The child's death was predominantly experienced as very peaceful (median, 9); 71% died at home. According to parents, involvement of the PPHCT led to highly significant (p<0.001) improvements in the children's symptoms and quality of life, as well as in aspects of communication and administrative barrier reduction. Anxiety was detected in 25% of parents, depression in 19%, and prolonged grief disorder in 13%. HCPs (return rate, 83%) evaluated all investigated care domains (particularly cooperation/communication/family support) as being significantly improved (p<0.001). Thirty-five percent of HCPs felt uncertain concerning pediatric palliative care; 79% would welcome specific training opportunities. CONCLUSIONS: Involvement of a PPHCT is experienced as a substantial improvement of care by parents and HCPs. Coordination of palliative care during the last phase of life appears to be an important quality factor for the home care of dying children and their families.

Didactique de la géographie et formation initiale des enseignants spécialistes : conception et première évaluation du nouveau dispositif de formation initiale des enseignants de géographie du Secondaire supérieur à la HEP Vaud

Geography as a school subject is specifically thought for and by the schools. The contents of the school subject, nowadays, do not reflect the concerns and the evolution of the discipline as such. Nevertheless, official curricula set school objectives that address issues affecting the world and people's lives. These issues are coherent with the ones addressed by geography as a social science, that is to say the study of how people and their environment interact and how societies are interconnected through space. On an every day basis, Geography as a school subject is most of the time reduced to accumulating knowledge outside any given context. This knowledge may even be partially untrue or old and the related activities focus on low cognitive tensions. These practices do not contribute to the learners' understanding of the world because it does not allow them to build a geographical competence, which they. will need as future citizens in order to make responsible choices when they are confronted to questions related to how the locations of human and physical features are influenced by each other and how they interact across space. The central part of the text relies on the ideas and the processes discussed in the publications, which constitute the published file; it is divided into two parts. The first part (chapter 4) presents a didactic approach, which gives meaningful insights into Geography as a school subject and shows a brief account of the theoretical background that supports it. This socio-constructivist approach relies on the main following features: a priming stage (élément déclencheur), which presents geographical knowledge as an issue to be explored, discussed or solved; the issue is given to learners;. the planning of the teaching-learning sequence in small units launched by the main issue in the priming stage ; the interconnections of geographical knowledge with integrative concepts ; the synthetic stage or reporting stage where final concepts and knowledge are put together in order to be learned. Such an approach allows learners to re-invest the knowledge they have built themselves. This knowledge is organised by geographical integrative concepts, which represent true thinking operative tools and with which key issues in the geographical thinking are associated. The second part of the text (chapter 5) displays the didactic principles that governed the conception of the new initial training course for the future upper secondary school teachers at the HEP Vaud. The ambition of this course is to prepare future teachers to plan and realize the teaching of geography that provides pupils with the tools to understand better how people and their environment interact and how societies are interconnected through space. One of the tools for the teachers is the conceptual framework, whose most salient interest is to be relevant at every stage of the preparation and planning of the teaching, including the necessary epistemological reflection that should always be present. The synthesis of the text starts with a short account of the first evaluation of the new course. Various reflections on the future concerns and issues, that the didactics and methodology of Geography will be confronted with, constitute the synthesis.

Relation between atherogenic dyslipidemia and the Adult Treatment Program-III definition of metabolic syndrome (Genetic Epidemiology of Metabolic Syndrome Project).

Genetic Epidemiology of Metabolic Syndrome is a multinational, family-based study to explore the genetic basis of the metabolic syndrome. Atherogenic dyslipidemia (defined as low plasma high-density lipoprotein cholesterol with elevated triglycerides (&lt;25th and &gt;75th percentile for age, gender, and country, respectively) identified affected subjects for the metabolic syndrome. This report examines the frequency at which atherogenic dyslipidemia predicts the metabolic syndrome of the National Cholesterol Education Program Adult Treatment Panel III (ATP-III). One thousand four hundred thirty-six (854 men/582 women) affected patients by our criteria were compared with 1,672 (737 men/935 women) unaffected persons. Affected patients had more hypertension, obesity, and hyperglycemia, and they met a higher number of ATP-III criteria (3.2 +/- 1.1 SD vs 1.3 +/- 1.1 SD, p &lt;0.001). Overall, 76% of affected persons also qualified for the ATP-III definition (Cohen's kappa 0.61, 95% confidence interval 0.59 to 0.64), similar to a separate group of 464 sporadic, unrelated cases (75%). Concordance increased from 41% to 82% and 88% for ages &lt; or =35, 36 to 55, and &gt; or =55 years, respectively. Affected status was also independently associated with waist circumference (p &lt;0.001) and fasting glucose (p &lt;0.001) but not systolic blood pressure (p = 0.43). Thus, the lipid-based criteria used to define affection status in this study substantially parallels the ATP-III definition of metabolic syndrome in subjects aged &gt;35 years. In subjects aged &lt;35 years, atherogenic dyslipidemia frequently occurs in the absence of other metabolic syndrome risk factors.

From controlling to letting go : what are the psychosocial needs of parents of adolescents with a chronic illness?

While one of the main objectives of adolescence is to achieve autonomy, for the specific population of adolescents with a chronic illness (CI), the struggle for autonomy is accentuated by the limits implied by their illness. However, little is known concerning the way their parents manage and cope with their children's autonomy acquisition. Our aim was to identify the needs and preoccupations of parents of adolescents with CI in coping with their children's autonomy acquisition and to determine whether mothers and fathers coped differently. Using a qualitative approach, 30 parents of adolescents with CI participated in five focus groups. Recruitment took place in five specialized pediatric clinics from our university hospital. Thematic analysis was conducted. Transcript analyses suggested four major categories of preoccupations, those regarding autonomy acquisition, giving or taking on autonomy, shared management of treatment and child's future. Some aspects implied differences between mothers' and fathers' viewpoints and ways of experiencing this period of life. Letting go can be hard for the father, mother, adolescent or all three. Helping one or the other can in turn improve family functioning as a whole. Reported findings may help health professionals better assist parents in managing their child's acquisition of autonomy.

Perinatal assessment of infant, parents, and parent-infant relationship: prematurity as an example.

This article reviews the stresses for parents, infants, and other caregivers during the period surrounding the birth of the premature infant. Principles of assessment of infant discomfort, parental stress, the parent-infant relationship, and the match of the medical caregiving environment to the individual infant's needs are discussed. Relevant tools to aide in these aspects of assessment are reviewed. The role of early assessment as preventive intervention and the indication for subsequent intervention in complicated cases of premature infants and their parents are further discussed. The article offers detailed clinical examples to illustrate these and other points throughout.

Bitumens in the late Variscan hydrothermal vein-type uranium deposit of Pribram, Czech Republic: Sources, radiation-induced alteration, and relation to mineralization

The late Variscan (275-278 Ma) Pribram uranium deposit is one of the largest known accumulations of uraniferous bitumens in hydrothermal veins. The deposit extends along the northwestern boundary of the Central Bohemian pluton (345-335 Ma) with low-grade metamorphosed Late Proterozoic and unmetamorphosed Cambrian rocks. From a net uranium production of 41,742 metric tons (t), more than 6,000 t were extracted from bitumen-uraninite ores during 43 years of exploration and mining. Three morphological varieties of solid bitumen are recognized: globular, asphaltlike, and cokelike. While the globular bitumen is uranium free, the other two types are uraniferous. The amount of bitumen in ore veins gradually decreases toward the contact with the plutonic body and increases with depth. Two types of bitumen microtextures are recognized using high-resolution transmission electron microscopy: amorphous and microporous, the former being less common in uraniferous samples. A lower Raman peak area ratio (1,360/1,575 cm(-1)) in mineralized bitumens (0.9) compared with uranium-free samples (2.0) indicates a lower degree of microtextural organization in the latter The H/C and O/C atomic ratios in uranium-free bitumens (0.9-1.1 and 0.09, respectively) are higher than those in mineralized samples (H/C = 0.3-0.8, O/C = 0.03-0.09). The chloroform extractable matter yield is Very low in uranium-free bitumens (0.30-0.35% of the total organic carbon,TOC) and decreases with uranium content increase. The extracted solid uraniferous bitumen infrared spectra show depletion in aliphatic CH2 and CH3 groups compared to uranium-free samples. The concentration of oxygen-bearing functional groups relative to aromatic bonds in the IR spectra of uranium-free and mineralized bitumen, however, do not differ significantly. C-13 NMR confirmed than the aromaticity of a uraniferous sample is higher (F-ar = 0.61) than in the uranium-free bitumen (F-ar = 0.51). Pyrolysates from uraniferous and nonuraniferous bitumens do not differ significantly, being predominantly cresol, alkylphenols, alkylbenzenes, and alkylnaphthalenes. The liquid pyrolysate yield decreases significantly with increasing uranium content. The delta(13)C Values of bulk uranium-free bitumens and low-grade uraniferous, asphaltlike bitumens range from -43.6 to 52.3 per mil. High-grade, cokelike, uraniferous bitumens are more C-13 depleted (54.5 to -58.4 parts per thousand). In contrast to the very light isotopic ratios of the high-grade uraniferous cokelike bitumen bulk carbon, the individual n-alkanes and isoprenoids (pristane and phytane) extracted from the same sample are significantly C-13 enriched. The isotopic composition of the C13-24 n-alkanes extracted from the high-grade uraniferous sample (delta(13)C = -28.0 to 32.6 parts per thousand) are heavier compared with the same compounds in a uranium-free sample (delta(13)C = 31.9 to 33.8 parts per thousand). It is proposed that the bitumen source was the isotopically light (delta(13)C = 35.8 to 30.2 parts per thousand) organic matter of the Upper Proterozoic host rocks that were pyrolyzed during intrusion of the Central Bohemian pluton. The C-13- depleted pyrolysates were mobilized from the innermost part of the contact-metamorphic aureole, accumulated in structural traps in less thermally influenced parts of the sedimentary complex and were later extracted by hydrothermal fluids. Bitumens at the Pribram deposit are younger than the main part of the uranium mineralization and were formed through water-washing and radiation-induced polymerization of both the gaseous and liquid pyrolysates. Direct evidence for pyrolysate reduction of uranium in the hydrothermal system is difficult to obtain as the chemical composition of the original organic fluid phase was modified during water-washing and radiolytic alteration. However, indirect evidence-e.g., higher O/C atomic ratios in uranium-free bitumens (0.1) relative to the Upper Proterozoic source rocks (0.02-0.05), isotopically very light carbon in associated whewellite (delta(13)C = 31.7 to -28.4 parts per thousand), and the striking absence of bitumens in the pre-uranium, hematite stage of the mineralization-indicates that oxidation of organic fluids may have contributed to lowering of aO(2) and uraninite precipitation.

Relation soignant-soigné quand les blogs s'en mêlent [Patient-caregiver relationship: when illness blogs step in].

The use of social media as a communication tool is rapidly growing in the community, and more specifically in patients, through illness blogs. This has been true for several years in North America, but is becoming a reality in Europe as well. We report here the first results of studies on the putative psychological benefits and risks of illness blogs for their authors. We also explore the possible impact of blogging on the patient-caregiver relationship. Social media are expected to have a growing influence in certain areas of health care. Physicians should therefore stay informed about them, take advantage of their benefits, and anticipate their risks.
