Spatial variation in the temporal change of male and female melanic ornamentation in the barn owl.

Because the magnitude of selection can vary between sexes and in space and time, sexually antagonistic selection is difficult to demonstrate. In a Swiss population of barn owls (Tyto alba), a heritable eumelanic colour trait (size of black spots on ventral feathers) was positively selected with respect to yearling survival only in females. It remains unclear whether the absence of negative selection in males is typical in this species. To tackle this issue indirectly, we measured the size of black spots in 1733 skin specimens collected by museums from 1816 to 2001 in seven European countries and in the Middle-East. The temporal change in spot size was sex- and country-specific. In males, spots became smaller particularly in three countries (Middle-East, Italy and Switzerland). In females, the size of spots increased significantly in two countries (UK and Spain) and decreased in two others (Germany and Switzerland). Because migration and phenotypic plasticity cannot explain these results, selection is the most likely cause. The weaker temporal change in spot size in females than males may be because of the combined effect of strong genetic correlation between the sexes and stronger negative selection in males than positive selection in females. We thus suggest that in the barn owl, spot size (or genetically correlated traits) is sexually antagonistically selected and that its pattern of selection may account for the maintenance of its variation and sexual dimorphism.

Insulin modulation of luteinizing hormone secretion in normal female volunteers and lean polycystic ovary syndrome patients.

BACKGROUND/AIMS: Endocrine features of polycystic ovary syndrome (PCOS) include altered ovarian steroidogenesis, hyperinsulinemia and abnormal luteinizing hormone (LH) secretion. This study was undertaken to further evaluate the role of insulin to modulate LH secretion in lean PCOS patients with normal insulin sensitivity and normal volunteers. METHODS: The study was performed in five nonobese patients diagnosed with PCOS on the basis of amenorrhea and a polycystic morphology at ovarian ultrasound, and 5 normal controls in early to mid-follicular phase and matched for weight and age. All subjects were phenotyped, and then admitted for 12 h of frequent (q 10') blood sampling on two separate occasions, once for a baseline study and the other time for a hyperinsulinemic and euglycemic clamp study. LH was measured in samples obtained throughout each admission in order to perform LH pulse analysis. RESULTS: Baseline LH secretion in PCOS subjects was significantly different from controls: they had higher LH levels, higher LH/FSH ratios as well as a faster LH pulse frequency than normal women. Insulin administration did not affect the pattern of LH secretion of PCOS patients, whereas it significantly increased the LH pulse frequency while decreasing the LH interpulse intervals in the controls. CONCLUSIONS: These data confirm that an abnormal pattern of LH secretion characteristic of PCOS can be observed in lean patients, and appears independent of peripheral insulin levels. Furthermore, our results in lean controls provide the first direct evidence that peripheral insulin can modulate the activity of hypothalamic gonadotropin-releasing hormone (GnRH) neurons in the human.

Female adolescents' views on a youth-friendly clinic

Rapport de synthèse : La satisfaction des patients concernant leur prise en charge fait maintenant partie intégrante de la qualité des soins. Elle a été évaluée à maintes reprises chez des patients adultes ou pédiatriques, mais rarement chez des patients adolescents. Les attentes des adolescents par rapport aux services de soins ont par contre été souvent étudiées et certains facteurs semblent particulièrement importants. Parmi ceux-ci, citons la confidentialité, le respect, l'honnêteté, l'écoute, l'accès aux soins ou le fait d'avoir des informations compréhensibles. L'Organisation Mondiale de la Santé a développé le concept de 'Youth-friendly health services' pour répondre aux besoins et attentes particuliers des adolescents. Il est basé sur sept principes : l'accessibilité, l'équité, l'efficience, l'efficacité, le fait d'être approprié et compréhensible. Notre objectif était d'évaluer la satisfaction des adolescentes consultant dans une clinique multidisciplinaire pour adolescents basée sur le modèle 'Youth-friendly health services' et de déterminer les facteurs qui y sont associés. Nous avons fait une enquête transversale dans une clinique pour adolescents à Lausanne entre mars et mai 2008 moyennant un questionnaire anonyme auto-administré. Tous les patients qui avaient consulté au moins une fois auparavant étaient éligibles. Nous avons ensuite éliminé les garçons, en très petit nombre et donc de faible valeur statistique. Trois cents onze patientes âgées de 12 à 22 ans ont été inclues dans l'étude. Nous avons effectué des analyses bivariées pour comparer les patientes satisfaites et non satisfaites puis avons construit un modèle log- linéaire afin de déterminer les facteurs directement ou indirectement liés à la satisfaction des patientes. Nonante-quatre pourcent des patientes étaient satisfaites. Les facteurs significativement associés à la satisfaction des adolescentes étaient les suivants : Les jeunes filles se sentaient plus écoutées en ce qui concerne leurs plaintes, et avaient plus l'impression que le soignant les comprenait. Elles avaient aussi moins changé de soignant durant le suivi, avaient plus l'impression d'avoir bénéficié du traitement adéquat et pensaient avoir plus suivi les conseils du soignant. Le modèle log-linéaire que nous avons effectué a mis en avant quatre facteurs directement liés à la satisfaction des patientes, qui sont la continuité des soins, le résultat de la prise en charge, l'adhérence au traitement et le sentiment d'être comprise par le soignant. Ces résultats mettent en avant l'importance de la relation interpersonnelle entre le soignant et le patient, mais rendent aussi attentif à des aspects qui pourraient être améliorés, en ce qui concerne par exemple la continuité des soins. En effet, une clinique comme la nôtre fait partie d'un hôpital de formation et le tournus fréquent des soignants est inévitable. Les changements de médecins et autres soignants devraient alors être préparés et expliqués aux patients avec la plus grande attention. L'adhérence au traitement semble être fortement liée à la satisfaction des patients, mais la nature de notre étude ne permet pas de conclure à une relation de cause à effet. Nous pouvons tout de même supposer qu'elle est une conséquence de la satisfaction des patients. Enfin, la confidentialité et l'accès aux soins souvent cités comme essentiels à la satisfaction des patients dans la littérature étaient secondaires dans notre étude. En conclusion, la satisfaction des adolescentes était principalement basée sur une relation de confiance de longue durée avec leurs soignants. Les pédiatres occupent une place privilégiée pour répondre à ces besoins parce qu'ils connaissent leurs patients depuis l'enfance. Ils devraient cependant garder à l'esprit que la relation avec le patient change au moment de l'adolescence et que les jeunes sont très sensibles à la relation de confiance interpersonnelle qu'ils ont avec leur médecin.

2007 State of Iowa Juvenile Justice and Delinquency Prevention Act Formule Grand Update

This document is Iowa’s 2007 JJDP Act formula grant three year plan update. When specific items of this plan are unchanged from the previously submitted 2006 plan, we have reflected accordingly in the respective topic areas of this document. The bulk of this 2007 plan is an “update” of the program plan completed since submission of the original 2006 plan. The Division of Criminal and Juvenile Justice Planning (CJJP) wrote Iowa’s three year plan update. CJJP is the state agency responsible for administering the JJDP Act in Iowa. Federal officials refer to state administering agencies as the state planning agency (SPA). The Plan was developed and approved by Iowa’s Juvenile Justice Advisory Council. That Council assists with administration of the JJDP Act, and also provides guidance and direction to the SPA, the Governor and the legislature regarding juvenile justice issues in Iowa. Federal officials refer to such state level groups as state advisory groups (SAG’s).

Sex-specific estimates of dispersal show female philopatry and male dispersal in a promiscuous amphibian, the alpine salamander (Salamandra atra).

Amphibians display wide variations in life-history traits and life cycles that should prove useful to explore the evolution of sex-biased dispersal, but quantitative data on sex-specific dispersal patterns are scarce. Here, we focused on Salamandra atra, an endemic alpine species showing peculiar life-history traits. Strictly terrestrial and viviparous, the species has a promiscuous mating system, and females reproduce only every 3 to 4 years. In the present study, we provide quantitative estimates of asymmetries in male vs. female dispersal using both field-based (mark-recapture) and genetic approaches (detection of sex-biased dispersal and estimates of migration rates based on the contrast in genetic structure across sexes and age classes). Our results revealed a high level of gene flow among populations, which stems exclusively from male dispersal. We hypothesize that philopatric females benefit from being familiar with their natal area for the acquisition and defence of an appropriate shelter, while male dispersal has been secondarily favoured by inbreeding avoidance. Together with other studies on amphibians, our results indicate that a species' mating system alone is a poor predictor of sex-linked differences in dispersal, in particular for promiscuous species. Further studies should focus more directly on the proximate forces that favour or limit dispersal to refine our understanding of the evolution of sex-biased dispersal in animals.

Female thyroid cancer : the role of reproductive and hormonal factors in Switzerland

We conducted a study on 91 women with thyroid cancer and 306 controls in hospital for acute nonneoplastic, non-hormone-related disorders in order to investigate the role of reproductive and hormonal factors in the etiology of epithelial thyroid cancer in the Canton of Vaud, Switzerland. Non-significant increases in cancer risk with an increasing number of full-term pregnancies (odds ratio, OR, after allowance for age and previous benign thyroid disease = 1.6, for > or = 3 vs. 0 full-term pregnancies, 95% confidence interval, CI: 0.7-3.6) and spontaneous abortions (OR = 2.0 for > or = 2 vs. 0 spontaneous abortions, 95% CI: 0.7-5.2) were seen. A significantly elevated OR (2.8, 95% CI: 1.1-7.2) was found in those women whose first pregnancy ended with an abortion. Whereas most other reproductive, menstrual and hormonal factors examined did not seem to affect the risk of thyroid cancer significantly, a clue emerged of an association between thyroid cancer and artificial menopause (OR = 6.3, for women who underwent artificial menopause vs. premenopausal women, 95% CI: 1.7-23.2). Although not necessarily causal, the relationship between the risk of epithelial thyroid cancer and the occurrence of spontaneous abortions and artificial menopause deserves attention in future studies, in the light of the high incidence of thyroid cancer in young and middle-aged women.
