European cancer mortality predictions for the year 2014.

BACKGROUND: From most recent available data, we projected cancer mortality statistics for 2014, for the European Union (EU) and its six more populous countries. Specific attention was given to pancreatic cancer, the only major neoplasm showing unfavorable trends in both sexes. PATIENTS AND METHODS: Population and death certification data from stomach, colorectum, pancreas, lung, breast, uterus, prostate, leukemias and total cancers were obtained from the World Health Organisation database and Eurostat. Figures were derived for the EU, France, Germany, Italy, Poland, Spain and the UK. Projected 2014 numbers of deaths by age group were obtained by linear regression on estimated numbers of deaths over the most recent time period identified by a joinpoint regression model. RESULTS: In the EU in 2014, 1,323,600 deaths from cancer are predicted (742,500 men and 581,100 women), corresponding to standardized death rates of 138.1/100,000 men and 84.7/100,000 women, falling by 7% and 5%, respectively, since 2009. In men, predicted rates for the three major cancers (lung, colorectum and prostate cancer) are lower than in 2009, falling by 8%, 4% and 10%, respectively. In women, breast and colorectal cancers had favorable trends (-9% and -7%), but female lung cancer rates are predicted to rise 8%. Pancreatic cancer is the only neoplasm with a negative outlook in both sexes. Only in the young (25-49 years), EU trends become more favorable in men, while women keep registering slight predicted rises. CONCLUSIONS: Cancer mortality predictions for 2014 confirm the overall favorable cancer mortality trend in the EU, translating to an overall 26% fall in men since its peak in 1988, and 20% in women, and the avoidance of over 250,000 deaths in 2014 compared with the peak rate. Notable exceptions are female lung cancer and pancreatic cancer in both sexes.

L'histoire naturelle au XVIe siècle : regards, lectures et discours sur la nature à travers l'exemple de La nature et diversité des poissons de Pierre Belon (1555)

Plan du travail Nous traiterons de cet aspect historique et contextuel dans la première partie. Les trois premiers chapitres décrivent les fondements antiques et médiévaux de la philosophie naturelle seiziémiste et évoquent l'influence du De animalibus d'Albert le Grand sur les médecins naturalistes. Nous en arriverons alors aux liens qui unissent ces derniers (chapitre IV) et aux conditions matérielles et intellectuelles qui entourent et parfois entravent la parution des ouvrages (chapitre V). Nous nous pencherons ensuite sur l'identité des lecteurs susceptibles d'être intéressés par les traités d'histoire naturelle. Ces lecteurs ont des attentes qui méritent aussi un examen quant à leur origine, car elles conditionnent pour une part variable, mais importante, le contenu des oeuvres (chapitre VI). Confrontés à des critiques, à des obstacles institutionnels parfois séculaires, les médecins naturalistes se défendent pour une part en reprenant les arguments de leurs prédécesseurs médiévaux. Mais nous les verrons mettre en place de nouvelles stratégies, en relation étroite avec le renouveau bien connu de la dialectique et de la rhétorique, qui trouve ses racines en Italie du nord à la fin du XVe siècle. Ce point sera développé dans la seconde partie, qui servira de transition essentielle dans notre exposé. C'est là que nous découvrirons que la rhétorique ne s'impose pas uniquement comme un rituel renouvelé de la dispute médiévale : elle n'entre pas seulement en jeu lorsqu'il s'agit de défendre ses intérêts contre des rivaux ou des adversaires académiques (chapitre VII). Les médecins naturalistes mettent au contraire au point des instruments au service d'un processus heuristique qui s'inspire des nouveaux canons de la rhétorique, dont Rudolph Agricola est un des théoriciens principaux (chapitre VIII). Ces observations nous amèneront à repréciser ce qu'il faut entendre par philosophie naturelle au XVIe siècle, notamment au travers de l'autorité de personnages comme Théodore Gaza (chapitre IX) et à définir les fondements généraux de l'histoire naturelle seiziémiste, en adoptant des points de vue divers : examen des tables des matières d'ouvrages, des réflexions des médecins naturalistes, avec à leur tête Conrad Gesner, ou encore étude de la pénétration de l'histoire naturelle dans quelques récits des voyageurs aux Amériques (chapitre X et XI). Arrivé à ce point de l'exposé, le lecteur aura constaté que la solidité de l'histoire naturelle seiziémiste tient à une stratégie discursive soigneusement élaborée. Le développement détaillé et l'application de ce nouveau processus, qui s'ancre au plus profond du discours descriptif de la nature, seront décrits dans la troisième partie. Nous commencerons par y rappeler quels sont les instruments antiques de la description des particulares, l'accident et la différence, que les médecins naturalistes adaptent à leurs exigences heuristiques (chapitre XII). Nous verrons le rôle de "nota", outil discursif méconnu, qui désigne les éléments décisifs ou arguments par lesquels les médecins naturalistes identifient les espèces décrites par les anciens en les confrontant aux espèces réelles (chapitre XIII). Une fois présenté l'instrument descriptif, se pose la question de son utilisation par les médecins naturalistes et de son évaluation par rapport au fonctionnement de la taxonomie moderne (chapitre XIV). La différence entre les deux regards sur la nature apparaîtra comme fondamentale : les médecins naturalistes assignent à leurs investigations des limites, inhérentes à l'origine sacrée de leur quête, qui relève de la philosophie, elle-même subordonnée à la théologie. Cela se percevra par exemple dans la description des animaux du Nouveau Monde. Les conséquences de cette constatation sont considérables : elles remettent en cause le statut du "savant" du XVIe siècle, qui ne saurait être assimilé à l'observateur extérieur tel que l'érige la science des Lumières. Belon et ses collègues se disent plutôt des "contemplateurs" et des interprètes, ce qui les rapprochent de la figure du poète, avec qui ils entretiennent des rapports ambivalents. C'est la relation même du médecin naturaliste au langage de la nature qui s'en trouve affectée : le savant n'a pas la maîtrise du discours, dans la mesure où les signes qu'il interprète et, dans une certaine mesure, ordonne, du latin : les noms d'espèces, entre autres dans les titres de notices descriptives, pour mieux cerner la relation entre la langue antique et la vernaculaire, ainsi que la notion de langue originelle chez les médecins naturalistes (chapitre XVIII). Les points communs qui émergeront de cette confrontation feront disparaître le clivage anachronique entre langue latine et langue vernaculaire, de même que l'hypothèse de l'insuffisance lexicale de la seconde, dont les médecins naturalistes auraient en vain voulu faire l'instrument de la science moderne (chapitre XIX). Le chapitre XX aura pour but d'établir le lien et l'adéquation entre les caractéristiques du discours descriptif ainsi mises en évidence et les fondements véritables de l'histoire naturelle seiziémiste.

PAR2 absence completely rescues inflammation and ichthyosis caused by altered CAP1/Prss8 expression in mouse skin.

Altered serine protease activity is associated with skin disorders in humans and in mice. The serine protease channel-activating protease-1 (CAP1; also termed protease serine S1 family member 8 (Prss8)) is important for epidermal homeostasis and is thus indispensable for postnatal survival in mice, but its roles and effectors in skin pathology are poorly defined. In this paper, we report that transgenic expression in mouse skin of either CAP1/Prss8 (K14-CAP1/Prss8) or protease-activated receptor-2 (PAR2; Grhl3(PAR2/+)), one candidate downstream target, causes epidermal hyperplasia, ichthyosis and itching. K14-CAP1/Prss8 ectopic expression impairs epidermal barrier function and causes skin inflammation characterized by an increase in thymic stromal lymphopoietin levels and immune cell infiltrations. Strikingly, both gross and functional K14-CAP1/Prss8-induced phenotypes are completely negated when superimposed on a PAR2-null background, establishing PAR2 as a pivotal mediator of pathogenesis. Our data provide genetic evidence for PAR2 as a downstream effector of CAP1/Prss8 in a signalling cascade that may provide novel therapeutic targets for ichthyoses, pruritus and inflammatory skin diseases.

Correlation of intra- and extraepidermal CD8 T cell numbers with development of psoriatic epidermal pathology

The development of psoriatic plaques is T cell dependent. Recently, Th17 CD4 T cells have been proposed to be the main effector cells. However, development of psoriasis is critically dependent on accumulation of epidermal T cells, among the majority express CD8. Here we show that numbers of epidermal CD8 T cells correlated with development of psoriasis in human biopsies, and that blockade of CD8 T cells by depleting antibodies inhibited development of psoriasis in the AGR xenotransplantation mouse model. In human dermis, both CD4 and CD8 T cell numbers correlated significantly with epidermal pathology, indicating a role for dermal CD4 T cells in orchestrating the development of psoriasiform changes induced by epidermis-infiltrating CD8 T cells.

Fracture risk and zoledronic acid therapy in men with osteoporosis.

BACKGROUND: Fractures in men are a major health issue, and data on the antifracture efficacy of therapies for osteoporosis in men are limited. We studied the effect of zoledronic acid on fracture risk among men with osteoporosis. METHODS: In this multicenter, double-blind, placebo-controlled trial, we randomly assigned 1199 men with primary or hypogonadism-associated osteoporosis who were 50 to 85 years of age to receive an intravenous infusion of zoledronic acid (5 mg) or placebo at baseline and at 12 months. Participants received daily calcium and vitamin D supplementation. The primary end point was the proportion of participants with one or more new morphometric vertebral fractures over a period of 24 months. RESULTS: The rate of any new morphometric vertebral fracture was 1.6% in the zoledronic acid group and 4.9% in the placebo group over the 24-month period, representing a 67% risk reduction with zoledronic acid (relative risk, 0.33; 95% confidence interval, 0.16 to 0.70; P=0.002). As compared with men who received placebo, men who received zoledronic acid had fewer moderate-to-severe vertebral fractures (P=0.03) and less height loss (P=0.002). Fewer participants who received zoledronic acid had clinical vertebral or nonvertebral fractures, although this difference did not reach significance because of the small number of fractures. Bone mineral density was higher and bone-turnover markers were lower in the men who received zoledronic acid (P<0.05 for both comparisons). Results were similar in men with low serum levels of total testosterone. The zoledronic acid and placebo groups did not differ significantly with respect to the incidence of death (2.6% and 2.9%, respectively) or serious adverse events (25.3% and 25.2%). CONCLUSIONS: Zoledronic acid treatment was associated with a significantly reduced risk of vertebral fracture among men with osteoporosis.

Quality of Web-based information on obsessive compulsive disorder.

BACKGROUND: The Internet is increasingly used as a source of information for mental health issues. The burden of obsessive compulsive disorder (OCD) may lead persons with diagnosed or undiagnosed OCD, and their relatives, to search for good quality information on the Web. This study aimed to evaluate the quality of Web-based information on English-language sites dealing with OCD and to compare the quality of websites found through a general and a medically specialized search engine. METHODS: Keywords related to OCD were entered into Google and OmniMedicalSearch. Websites were assessed on the basis of accountability, interactivity, readability, and content quality. The "Health on the Net" (HON) quality label and the Brief DISCERN scale score were used as possible content quality indicators. Of the 235 links identified, 53 websites were analyzed. RESULTS: The content quality of the OCD websites examined was relatively good. The use of a specialized search engine did not offer an advantage in finding websites with better content quality. A score ≥16 on the Brief DISCERN scale is associated with better content quality. CONCLUSION: This study shows the acceptability of the content quality of OCD websites. There is no advantage in searching for information with a specialized search engine rather than a general one. Practical implications: The Internet offers a number of high quality OCD websites. It remains critical, however, to have a provider-patient talk about the information found on the Web.

Tree line shifts in the Swiss Alps: Climate change or land abandonment?

Questions: Did the forest area in the Swiss Alps increase between 1985 and 1997? Does the forest expansion near the tree line represent an invasion into abandoned grasslands (ingrowth) or a true upward shift of the local tree line? What land cover / land use classes did primarily regenerate to forest, and what forest structural types did primarily regenerate? And, what are possible drivers of forest regeneration in the tree line ecotone, climate and/or land use change? Location: Swiss Alps. Methods: Forest expansion was quantified using data from the repeated Swiss land use statistics GEOSTAT. A moving window algorithm was developed to distinguish between forest ingrowth and upward shift. To test a possible climate change influence, the resulting upward shifts were compared to a potential regional tree line. Results: A significant increase of forest cover was found between 1650 to and 2450 m. Above 1650 m, 10% of the new forest areas were identified as true upward shifts whereas 90% represented ingrowth, and we identified both land use and climate change as likely drivers. Most upward shift activities were found to occur within a band of 300 m below the potential regional tree line, indicating land use as the most likely driver. Only 4% of the upward shifts were identified to rise above the potential regional tree line, thus indicating climate change. Conclusions: Land abandonment was the most dominant driver for the establishment of new forest areas, even at the tree line ecotone. However, a small fraction of upwards shift can be attributed to the recent climate warming, a fraction that is likely to increase further if climate continues to warm, and with a longer time-span between warming and measurement of forest cover.
