Systematic Review Protocol to Evaluate the Effectiveness and Cost Effectiveness of Personalised Surveillance after Colorectal Adenomatous Polypectomy

Lifetime risk of developing colorectal cancer (CRC) is 5% and five-year survival at early-stage is 92%. CRC risk following index colonoscopy should establish post-screening surveillance benefit, which may be greater in high-risk patients. This review evaluated published cost-effectiveness estimates of post-polypectomy surveillance to assess the potential for personalised recommendations by risk sub-group. Current data suggested colonoscopy identifies those at low-risk of CRC, who may not benefit from intensive surveillance, which risks unnecessary harms and inefficient use of colonoscopy resources. Meta-analyses of incidence of advanced-neoplasia post-polypectomy for low-risk was comparable to those without adenoma; both rates were under the lifetime risk of 5%. Therefore, greater personalisation through de-intensified strategies for low-risk individuals could be beneficial and could employ non-invasive testing such as faecal immunochemical tests (FIT) combined with primary prevention or chemoprevention, thereby reserving colonoscopy for targeted use in personalised risk-stratified surveillance.
This systematic review aims to:
1. Assess if there is evidence supporting a program of personalised surveillance in patients with colorectal adenoma according to risk sub-group.
2. Compare the effectiveness of surveillance colonoscopy with alternative prevention strategies.
3. Assess trade-off between costs, benefits and adverse effects which must be considered in a decision to adopt or reject personalised surveillance.

An exploration of men’s experiences of undergoing active surveillance for favourable-risk prostate cancer: A mixed methods study protocol

Background
Prostate cancer is one of the most common male cancers worldwide. Active Surveillance (AS) has been developed to allow men with lower risk disease to postpone or avoid the adverse side effects associated with curative treatments until the disease progresses. Despite the medical benefits of AS, it is reported that living with untreated cancer can create a significant emotional burden for patients.

Methods/design
The aim of this study is to gain insight into the experiences of men eligible to undergo AS for favourable-risk PCa.

This study has a mixed-methods sequential explanatory design consisting of two phases: quantitative followed by qualitative. Phase 1 has a multiple point, prospective, longitudinal exploratory design. Ninety men diagnosed with favourable-risk prostate cancer will be assessed immediately post-diagnosis (baseline) and followed over a period of 12 months, in intervals of 3 month. Ninety age-matched men with no cancer diagnosis will also be recruited using peer nomination and followed up in the same 3 month intervals. Following completion of Phase 1, 10–15 AS participants who have reported both the best and worst psychological functioning will be invited to participate in semi-structured qualitative interviews. Phase 2 will facilitate further exploration of the quantitative results and obtain a richer understanding of participants’ personal interpretations of their illness and psychological wellbeing.

Discussion
To our knowledge, this is the first study to utilise early baseline measures; include a healthy comparison group; calculate sample size through power calculations; and use a mixed methods approach to gain a deeper more holistic insight into the experiences of men diagnosed with favourable-risk prostate cancer.

Iowa Surveillance of Notifiable and Other Diseases Annual Report, 2014 Amended May 2, 2016

***********Amended Report, May 2, 2016*************** Promoting and protecting the health of Iowans is the mission of the Iowa Department of Public Health (IDPH). Surveillance of notifiable health conditions is essential in establishing what, how, and when events impact the public’s health. Once this information is gathered, public health and health care providers around the state are able to use this data to take steps to prevent illnesses from occurring. Multiple divisions and bureaus are dedicated to accomplishing the goals of surveillance. In 2014, there were more than 86,000 laboratory results of infectious diseases and conditions submitted to IDPH disease surveillance programs. IDPH also investigates non-infectious conditions related to lead, occupational, and environmental hazards like carbon monoxide. In 2014, approximately 71,000 children’s and more than 7,000 adults’ blood tests results were reported to IDPH.

La suggestion de pistes narratives - Comment évoquer une histoire, un souvenir, un instant en art vidéo

L’essentiel de ce texte se veut une réflexion sur la manière de raconter une histoire ou, plutôt, de l’évoquer : un questionnement qui fonde ma pratique de l’image photographique et vidéographique. Afin de mener à bien cette réflexion, plusieurs aspects de mon questionnement par rapport à l’image seront abordés : la notion de véracité historique, l’image photographique, l’image d’archives, la complexité, un « univers de possibles », ainsi que l’analyse de ma méthodologie de travail. Cet approfondissement théorique sera développé de connivence avec ma pratique visuelle qui, dans le cadre de ma maîtrise en arts visuels, s’est principalement déployée sous la forme de l’installation vidéographique. Mots-clés : histoire, archives, évocation, complexité, art vidéographique.

Dynamique des ambiances lumineuses - approche basée sur la photométrie vidéo d’espaces de transition

Les variations de la lumière naturelle lors du passage d’un espace à un autre caractérisent de manière complexe, mais importante le design d’un bâtiment. Cette adaptation visuelle s’inscrit dans un processus spatiotemporel et influe sur le confort et le bien-être de ses occupants. La littérature fait état du peu de connaissances de la relation lumière espace-temps. Cette recherche propose donc d’étudier cette relation spatio-temporelle existant entre la lumière et l’espace, afin de qualifier un parcours architectural au moyen d’une expérimentation in situ et de segments filmiques. La recherche combine l’utilisation d’un luminance-mètre, d’une caméra vidéo et d’une méthode d’analyse d’images numériques afin de permettre l’évaluation des qualités spatio-temporelles de la lumière. Le parcours architectural est analysé selon la diversité et l’intensité des ambiances lumineuses en fonction du temps permettant de décrire les perceptions visuelles d’espaces transitions. Cette méthode dynamique offre un potentiel d’analyse et de création aux concepteurs désireux d’enrichir le design de séquences spatiales en favorisant la diversité lumineuse dans l’expérience architecturale. Mots clefs: adaptation visuelle, analyse d’images, ambiance lumineuse, contraste, éclairage naturel, espaces transitions, lumière perception visuelle, vidéo, spatio-temporel.

Avian Cholera emergence in Arctic-nesting northern Common Eiders: using community-based, participatory surveillance to delineate disease outbreak patterns and predict transmission risk

Emerging infectious diseases are a growing concern in wildlife conservation. Documenting outbreak patterns and determining the ecological drivers of transmission risk are fundamental to predicting disease spread and assessing potential impacts on population viability. However, evaluating disease in wildlife populations requires expansive surveillance networks that often do not exist in remote and developing areas. Here, we describe the results of a community-based research initiative conducted in collaboration with indigenous harvesters, the Inuit, in response to a new series of Avian Cholera outbreaks affecting Common Eiders (Somateria mollissima) and other comingling species in the Canadian Arctic. Avian Cholera is a virulent disease of birds caused by the bacterium Pasteurella multocida. Common Eiders are a valuable subsistence resource for Inuit, who hunt the birds for meat and visit breeding colonies during the summer to collect eggs and feather down for use in clothing and blankets. We compiled the observations of harvesters about the growing epidemic and with their assistance undertook field investigation of 131 colonies distributed over >1200 km of coastline in the affected region. Thirteen locations were identified where Avian Cholera outbreaks have occurred since 2004. Mortality rates ranged from 1% to 43% of the local breeding population at these locations. Using a species-habitat model (Maxent), we determined that the distribution of outbreak events has not been random within the study area and that colony size, vegetation cover, and a measure of host crowding in shared wetlands were significantly correlated to outbreak risk. In addition, outbreak locations have been spatially structured with respect to hypothesized introduction foci and clustered along the migration corridor linking Arctic breeding areas with wintering areas in Atlantic Canada. At present, Avian Cholera remains a localized threat to Common Eider populations in the Arctic; however expanded, community-based surveillance will be required to track disease spread.

Identification des motivations pour le jeu vidéo: Revue des typologies des joueurs

Les jeux vidéo, bien que souvent associés au divertissement, sont de plus en plus utilisés à des fins pratiques en raison de leurs aptitudes à soutenir la motivation intrinsèque des joueurs. Afin de bien répondre aux préférences des joueurs, il devient important de comprendre quels facteurs permettent de soutenir ce type de motivation. Malgré la vaste littérature sur le sujet, aucune étude n’a avancé un modèle des motivations pour les jeux vidéo accepté de façon unanime. D’une part, plusieurs modèles fréquemment recensés dans les écrits ne sont supportés par aucune étude empirique. D’une autre part, les modèles ayant reçu un appui empirique sont souvent spécifiques à un type de jeu, ou divergent les uns des autres en raison d’une interprétation restreinte des analyses factorielles. Par conséquent, la présente étude cherche à proposer un modèle des motivations pour les jeux vidéo unifiant les différents modèles présents dans les écrits. Un questionnaire portant sur les comportements et les préférences des joueurs a été développé afin de tester la validité d’un modèle théorique récent des motivations pour les jeux vidéo et d’explorer les motivations des joueurs dans la population générale. Cent cinquante-six participants (41 Femmes; Mage = 25.95) ont complétés le questionnaire dans le cadre d’une expérience portant sur les jeux vidéo ou en ligne. Une analyse factorielle confirmatoire n’a pas permis de confirmer la structure du modèle théorique étudié. Plutôt, une analyse en composantes principales exploratoire a révélé la présence de sept composantes. Enfin, sept facteurs récurrents à travers les modèles supportés empiriquement ont été identifiés : la socialisation, la compétition, l’accomplissement, l’immersion, l’échappement, l’autonomie, et l’auto-actualisation. Ce modèle propose une base sur laquelle les études futures pourront bâtir, ainsi qu’un modèle préliminaire pouvant contribuer au développement de jeux favorisant la motivation intrinsèque des joueurs.
