Pre-diagnostic concordance with the WCRF/AICR guidelines and survival in European colorectal cancer patients: a cohort study.

BACKGROUND Cancer survivors are advised to follow lifestyle recommendations on diet, physical activity, and body fatness proposed by the World Cancer Research Fund/American Institute of Cancer Research (WCRF/AICR) for cancer prevention. Previous studies have demonstrated that higher concordance with these recommendations measured using an index score (the WCRF/AICR score) was associated with lower cancer incidence and mortality. The aim of this study was to evaluate the association between pre-diagnostic concordance with WCRF/AICR recommendations and mortality in colorectal cancer (CRC) patients. METHODS The association between the WCRF/AICR score (score range 0-6 in men and 0-7 in women; higher scores indicate greater concordance) assessed on average 6.4 years before diagnosis and CRC-specific (n = 872) and overall mortality (n = 1,113) was prospectively examined among 3,292 participants diagnosed with CRC in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort (mean follow-up time after diagnosis 4.2 years). Multivariable Cox proportional hazard models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for mortality. RESULTS The HRs (95% CIs) for CRC-specific mortality among participants in the second (score range in men/women: 2.25-2.75/3.25-3.75), third (3-3.75/4-4.75), and fourth (4-6/5-7) categories of the score were 0.87 (0.72-1.06), 0.74 (0.61-0.90), and 0.70 (0.56-0.89), respectively (P for trend <0.0001), compared to participants with the lowest concordance with the recommendations (category 1 of the score: 0-2/0-3). Similar HRs for overall mortality were observed (P for trend 0.004). Meeting the recommendations on body fatness and plant food consumption were associated with improved survival among CRC cases in mutually adjusted models. CONCLUSIONS Greater concordance with the WCRF/AICR recommendations on diet, physical activity, and body fatness prior to CRC diagnosis is associated with improved survival among CRC patients.

Cancer pulmonaire: lobectomie par thoracoscopie [VATS lobectomy for early-stage primary lung cancer].

Lobectomy via video-assisted thoracoscopic surgery (VATS) is now considered as a valid alternative to conventional thoracotomy for early-stage primary lung cancer. Various studies have reported that VATS lobectomy is a safe technique associated with fewer postoperative complications and better post-operative recovery than open thoracotomy. Furthermore, studies suggest oncological equivalence between VATS and open lobectomy.

To the Editor: The value of angiotensin-converting– enzyme (ACE) inhibitors, beta-blockers, and spironolactone has been well established by the results of numerous clinical trials. About 70 percent of the patients described by Rose et al. were treated with ACE inhibitors or angiotensin II–receptor antagonists; 35 to 40 percent received spironolactone, and only about 20 percent received beta-blockers. Thus, this population cannot have been considered to be optimally treated from the point of view of medical therapy.

Results from a multicentre international registry of familial Mediterranean fever: impact of environment on the expression of a monogenic disease in children.

BACKGROUND AND AIM: Familial Mediterranean fever (FMF) is an autoinflammatory disease caused by mutations of the MEFV gene. We analyse the impact of ethnic, environmental and genetic factors on the severity of disease presentation in a large international registry. METHODS: Demographic, genetic and clinical data from validated paediatric FMF patients enrolled in the Eurofever registry were analysed. Three subgroups were considered: (i) patients living in the eastern Mediterranean countries; (ii) patients with an eastern Mediterranean ancestry living in western Europe; (iii) Caucasian patients living in western European countries. A score for disease severity at presentation was elaborated. RESULTS: Since November 2009, 346 FMF paediatric patients were enrolled in the Eurofever registry. The genetic and demographic features (ethnicity, age of onset, age at diagnosis) were similar among eastern Mediterranean patients whether they lived in their countries or western European countries. European patients had a lower frequency of the high penetrance M694V mutation and a significant delay of diagnosis (p<0.002). Patients living in eastern Mediterranean countries had a higher frequency of fever episodes/year and more frequent arthritis, pericarditis, chest pain, abdominal pain and vomiting compared to the other two groups. Multivariate analysis showed that the variables independently associated with severity of disease presentation were country of residence, presence of M694V mutation and positive family history. CONCLUSIONS: Eastern Mediterranean FMF patients have a milder disease phenotype once they migrate to Europe, reflecting the effect of environment on the expression of a monogenic disease.

PFAPA syndrome is not a sporadic disease.

OBJECTIVES: To determine whether PFAPA (periodic fever, aphthous stomatitis, pharyngitis and cervical adenitis) patients have a positive family history (FH) for recurrent fever syndromes. METHOD: For all patients with PFAPA seen in two paediatric rheumatology centres (Romandy, Switzerland and Bordeaux, France), parents were interviewed to record the FH for periodic fever. As controls, we interviewed a group of children without history of recurrent fever. RESULTS: We recruited 84 patients with PFAPA and 47 healthy children. The FH for recurrent fever (without an infectious cause and recurring for at least half a year) was positive in 38/84 (45%), and was positive for PFAPA (diagnosis confirmed by a physician) in 10/84 (12%) of the PFAPA patients. For 29 of the 38 patients with positive FH, the affected person was a sibling or a parent. None of the healthy children had a positive FH for recurrent fever or PFAPA. A positive FH for rheumatological diseases was seen in both groups of children. CONCLUSION: These data show that a significant percentage of PFAPA patients present a positive FH of recurrent fever and PFAPA. This familial susceptibility suggests a potential genetic origin for this syndrome.

Late Pliensbachian-Early Toarcian (Early Jurassic) environmental changes in an epicontinental basin of NW Europe (Causses area, central France): A micropaleontological and geochemical approach

We present an integrated work based on calcareous nannofossil and benthic foraminiferal assemblages, and geochemical analyses of two Upper Pliensbachian-Lower Toarcian sections located in the central-South France. The studied sections, Tournadous and Saint-Paul-des-Fonts, represent the proximal and the distal part, respectively, of the Jurassic Causses Basin, one of the small, partly enclosed basins belonging to the epicontinental shelf of the NW Tethys. At the transition from Late Pliensbachian to Early Toarcian, the Causses Basin recorded an emersion in response to the global sea-level fall. Our data indicate severe environmental conditions of marine waters, including salinity decrease and anoxia development, occurring in the Early Toarcian. The acme of this deterioration coincides with the Early Toarcian Anoxic Event (T-OAE) but, due to the restricted nature of the basin. anoxia persisted until the end of the Early Toarcian. mainly in the deeper parts of the basin. The micronutrients and organic organic-matter fluxes were probably high during the entire studied time interval, as shown by nannofossil and foraminiferal assemblages. However, nannoplankton production drastically decreased during the T-OAE, as demonstrated by very low nannofossil fluxes, and only taxa tolerant to low-saline surface waters could thrive. At the same time, benthic foraminifers temporarily disappeared in response to sea-bottom anoxia. Our study demonstrates that environmental changes related to the T-OAE are well-recorded even in small, partly enclosed basins of NW Europe, like the Causses Basin. Within this area, the effects of global changes. like sea sea-level and temperature fluctuations, are modulated by local conditions mainly controlled by the morphology of the basin.

Effets des usages différenciés de l'activité physique sur des enfants en classe enfantine : étude pluridisciplinaire et comparative

La thèse traite de projets de classes enfantines avec de l'activité physique, projets pilotes ayant entre autres le but d'évaluer les effets d'un apport d'activité physique auprès d'enfants de 4 à 6 ans. Le projet de recherche saisit l'opportunité de pouvoir observer les effets de l'AP sur de jeunes enfants (n=86, classes AP=40, classes contrôles=46) et ceci par trois regards distincts : une quantification de l'activité physique, l'influence de cette dernière sur certaines composantes cognitives (créativité, intelligence et concentration) des jeunes enfants et, enfin, l'influence de l'activité physique au niveau psychosocial (microsystèmes familial et scolaire). La méthodologie mélange des méthodes qualitatives (entretiens, observations) et quantitatives (accéléromètres (GT1M), tests de créativité (Krampen, 1996), d'intelligence (Cattell, Weiss & Osterland, 1997), de concentration (Krampen, 2007)). Les principaux résultats démontrent que ce type de projet permet d'augmenter l'AP durant le temps scolaire et les résultats sont plus contrastés en extrascolaire. Un temps supérieur consacré à l'AP ne démontre aucune diminution des capacités cognitives dans cette tranche d'âge-là. L'analyse du microsystème familial nous informe sur le fait que les parents qui ont placé leurs enfants dans ce type de classes sont eux-mêmes plus actifs que la moyenne de la population suisse (Lamprecht, Fischer, & Stamm, 2008a). Enfin, un apport d'AP ne permet pas d'augmenter le nombre de feedbacks tournés vers l'autonomie et le style contrôlant est même renforcé. Nos résultats sont discutés sur la base des études de Kriemler et al. (2010) qui démontrent toute la difficulté d'une intervention scolaire pour modifier les comportements familiaux en extrascolaire. La fonction exécutive (Tomporowski et al., 2008) offre un regard neurophysiologique éclairant les effets de l'AP sur les différentes capacités étudiées. Enfin, il semble que la pression générée par la mise en place de projets liés à un apport d'AP en école enfantine va dans le sens d'une augmentation d'un style contrôlant (Tessier, 2006). Ce choix d'approcher les observations selon plusieurs angles d'étude est audacieux car il se situe en situation écologique mais il représente en même temps le seul moyen d'observer les effets en tenant davantage compte de la complexité des conduites des interactions entre différents facteurs. - The aim of the study is to evaluate the effect of physical activity (PA) in kindergartens with children aged from 4 to 6 years old. The project seizes the opportunity to observe the effects of PA on young children (n=86, classes AP=40, control classes=46) with three different axes: a quantification of PA, the influence of PA on cognitive functions (creativity, intelligence and concentration), and the influence on the family and the climate in the class. The methodology is based on a mix of qualitative (interviews, observations) and quantitative (accelerometer (GT1M), creativity test (Krampen, 1996), intelligence test (Cattell, Weiss & Osterland, 1997), concentration test (Krampen, 2007)) methods. The main results show that PA during the schooltime increased and the results outside of the school present more contrasts. More time spent for PA doesn't influence negatively the evolution of the cognitive functions at this age. The parents, who have interest for this kind of kindergartens for their children move significantly more than the Swiss population (Lamprecht, et al., 2008a). More PA during the lessons doesn't increase the feedbacks given with autonomy and more control is even observed. The results show the difficulty of changing the behaviors of a family linked to PA outside of the school (Kriemler et al., 2010). The discussion of the results of the cognitive functions is based on the executive function, which seems to be linked to PA (Tomporowski et al., 2008). Finally, it seems that the pressure occurred by those projects with PA tend to foster a climate with more control (Tessier, 2006). The choice of structuring the thesis with three different axes represents a risk because it is established in ecological conditions, but it also allows to observe the effects of PA taking into consideration the interactions between the different factors.

Jalkaterapian asiakkaiden jalkojen omahoitotottumukset vuosina 2003-2005

Tutkimuksen tavoitteena oli kartoittaa Helsingin ammattikorkeakoulu Stadian jalkapisteessä hoidossa käyneiden eri-ikäisten asiakkaiden (n=346) jalkojen omahoitotottumukset ja niiden tarkoituksenmukaisuus sekä jalkaterien terveyden taso. Tutkimukseen osallistuneiden ikäjakauma oli 6-96 ja keski-ikä 60 vuotta. Kysely toteutettiin Kunto-Stadian jalkapisteessä opiskelijoiden harjoittelujaksoilla vuosina 2003-2005. Tutkimusstrategia oli kvantitatiivinen ja tiedonhankintamenetelmänä oli strukturoitu kyselylomake. Tulokset on esitetty käyttäen frekvenssejä ja prosenttiosuuksia. Tulosten mukaan suurin osa vastanneista pesi jalat päivittäin ja kuivasi varvasvälit joka pesun yhteydessä. Vajaa puolet rasvasi jalat harvemmin kuin kerran viikossa tai ei lainkaan. Noin puolet käytti jalkojen ihon hoidossa raspia. Noin puolet käytti luonnonkuitusukkia. Yksi kymmenestä liikkui sisätiloissa sukkasillaan. Hieman yli puolelle kenkien löytyminen oli vaikeata. Alle kolmasosa harrasti yhtä tai kahta liikuntalajia. Yleisimmin harrastettiin kävelyä. Alle puolet harrasti liikuntaa 3-4 kertaa viikossa. Alle puolet ei toteuttanut jalkavoimistelua. Johtopäätöksenä voidaan todeta, että jalkahygienian taso on huono, koska jalkojen omahoitotietoudessa on puutteita. Tässä tutkimuksessa sukat ja kengät tukevat jalkojen terveyttä melko huonosti. Tutkimustulosten mukaan sukkia vaihdetaan liian harvoin, jonka seurauksena jalkahygienia kärsii. Kenkätottumukset eivät tue pystyasentoa ja liikkumista. Tutkimukseen osallistuneet harrastavat yksipuolista liikuntaa, koska tutkimustuloksista ilmenee, että suurin osa harrastaa yhtä tai kahta liikuntalajia. Jalkavoimistelua harrastettiin liian vähän, jonka seurauksena jalkaterän ja säären alueen lihastasapaino häiriintyy ja nivelten toiminta kärsii. Suomessa ja ulkomailla ei ole aiemmin tehty näin laajaa tutkimusta jalkojen omahoitotottumuksista. Ammattikuntamme ja muu terveydenhuoltohenkilöstö saavat ajankohtaista ja syventävää tietoa, jolloin jalkaongelmien syntymistä voidaan ehkäistä puuttumalla ajoissa opetuksen ja ohjauksen avulla puutteellisiin jalkojen omahoitotottumuksiin. Toivomme tämän tutkimuksen kannustavan jalkojenhoitajia ja jalkaterapeutteja panostamaan jatkossa yksilölliseen asiakkaan opetukseen ja ohjaukseen sekä kehittämisehdotusten perusteella muokatun jalkojen omahoitolomakeen motivoivan entistä enemmän keräämään tietoja asiakkaiden jalkojen omahoitotottumuksista. Kysymykset on muokattu tutkimustulosten ja opinnäytetyön tekovaiheessa ilmenneiden kehitystarpeiden perusteella.

Neurotoxicant-induced inflammatory response in three-dimensional brain cell cultures.

Brain inflammatory response is triggered by the activation of microglial cells and astrocytes in response to various types of CNS injury, including neurotoxic insults. Its outcome is determined by cellular interactions, inflammatory mediators, as well as trophic and/or cytotoxic signals, and depends on many additional factors such as the intensity and duration of the insult, the extent of both the primary neuronal damage and glial reactivity and the developmental stage of the brain. Depending on particular circumstances, the brain inflammatory response can promote neuroprotection, regeneration or neurodegeneration. Glial reactivity, regarded as the central phenomenon of brain inflammation, has also been used as an early marker of neurotoxicity. To study the mechanisms underlying the glial reactivity, serum-free aggregating brain cell cultures were used as an in vitro model to test the effects of conventional neurotoxicants such as organophosphate pesticides, heavy metals, excitotoxins and mycotoxins. This approach was found to be relevant and justified by the complex cell-cell interactions involved in the brain inflammatory response, the variability of the glial reactions and the multitude of mediators involved. All these variables need to be considered for the elucidation of the specific cellular and molecular reactions and their consequences caused by a given chemical insult.

O primeiro centro urbano colonial nos trópicos: Ribeira Grande (Cabo Verde), séculos XV-XVII.

A cidade da Ribeira Grande não resulta de uma selecção natural das populações ao longo dos tempos, atraídas por um local que apresente as várias condições favoráveis à evolução da vida comunitária. Ela é fundada por decisão administrativa num vazio populacional, de clima adverso, por razões exógenas ao território. Quando esses condicionalismos externos se alteram e a retaguarda se povoa, a cidade decai e a população ruraliza-se. A ilha de Santiago e designadamente o porto da Ribeira Grande tornaram-se, no 3º quartel do séc. XV, objecto de atenções por parte da política ultramarina da Coroa portuguesa devido à sua possível função de “fortaleza feitoria insular” da Costa da Guiné.1 Efectivamente, por razões estratégicas os portugueses inventaram um pólo de atracção tão intenso, quanto nele confluíam todas as linhas que estabeleciam a ligação entre a ilha e o extenso litoral fronteiro. O porto insular foi um litoral fabricado, para ocupação sem resistências, dispondo de uma retaguarda passiva, utilizável a qualquer momento.2

Quality assurance of the EORTC 22043-30041 trial in post-operative radiotherapy in prostate cancer: Results of the Dummy Run procedure.

BACKGROUND AND PURPOSE: The EORTC 22043-30041 trial investigates the role of the addition of androgen suppression to post-operative radiotherapy in patients who have undergone radical prostatectomy. As part of the quality assurance of radiotherapy (QART) a Dummy Run (DR) procedure was performed. MATERIALS AND METHOD: The protocol included detailed and published delineation guidelines. Participating institutions digitally submitted radiotherapy treatment volumes and a treatment plan for a standard clinical case. Submissions were centrally reviewed using the VODCA software platform. RESULTS: Thirty-eight submissions from thirty-one institutions were reviewed. Six were accepted without comments. Twenty-three were accepted with comments on one or more items: target volume delineation (22), OAR delineation (23), planning and dosimetry (3) or treatment verification (1). Nine submissions were rejected requiring resubmission, seven for target volume delineation reasons alone. Intervention to highlight the importance of delineation guidelines was made prior to the entry of the first patient in the trial. After this, a lower percentage of resubmissions was required. CONCLUSIONS: The EORTC 22043-30041 Dummy Run highlights the need for timely and effective QART in clinical trials. The variation in target volume and OAR definition demonstrates that clinical guidelines and radiotherapy protocols are not a substitute for QART procedures. Early intervention in response to the Dummy Run improved protocol understanding.
