Bounded cocycles: von Neumann algebras and amenability.
Creators: name: Bates, Teresa.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1995
Subjects: subject: Mathematics.

description: In a 1993 preprint Guyan Robertson proved that every uniformly bounded representation of a discrete group on a finite von Neumann algebra is similar to a unitary representation. We have since discovered that this result was first proved in a paper of Vasilescu and Zsido, published in 1974 (VZ). In this thesis we generalise this result for discrete groupoids, proving that every uniformly bounded cocycle into a finite von Neumann algebra is cohomologous to a unitary cocycle. The corresponding result for cocycles into finite dimensional algebras was proved in (Zim3). We also derive some equivalent definitions of amenability of group actions and provide a new proof of a result of Zimmer regarding uniformly bounded cocycles on amenable G-spaces. We develop some machinery in order to prove these results. This is the theory of ${\cal G}$-flows in which we explore the actions of groupoids on Borel fields of sets. Our development of this theory follows that of the usual theory of flows from topological dynamics.

description: Introducción: Existe una evidencia creciente de que el género tienen un impacto en las diferencias de resultados en distintas enfermedades (Hertler et al, 2020), no siendo nuevo el estudio de las diferencias de género en psicopatología (Andreasen, 1997). En este sentido, se señala que los problemas de salud mental son de predominio femenino en los adultos (Salud mental en datos, 2020).

 

Objetivos: Determinar, desde la Psiquiatría de Enlace, las diferencias de género en la morbilidad y mortalidad de las personas ingresadas en el hospital general por patologías médico-quirúrgicas.

 

Material y métodos: Material: Variables sociodemográficas (edad, sexo), clínicas (diagnóstico psiquiátrico global realizado desde la interconsulta, tipo de patología somática concomitante, patologías somáticas comórbidas) y asistenciales (derivación al alta, mortalidad). Método: Diseño del estudio: Estudio epidemiológico prospectivo sobre 2184 interconsultas psiquiátricas solicitadas desde el 1 de enero de 2012 hasta el 31 de diciembre de 2018. Consideraciones bioéticas: El estudio forma parte de un proyecto más amplio, el Estudio AQUILES (Análisis de la Interconsulta de PsiQUIatría en el CompLEjo ASistencial de Zamora: estudio retrospectivo de los años 2012 a 2018), aprobado por el Comité de Ética de la Investigación con Medicamentos (CEIm) de Área.

 

Resultados: De las 2184 interconsultas, 1014 (46,4%) fueron mujeres. No diferencias en la edad media de varones (65,31 años) y mujeres (65,73). El diagnóstico psiquiátrico global diferencial realizado desde la interconsulta fue en varones los trastornos por uso de sustancias (26%, p 0,000) y las psicosis (9,1%, p 0,000); y en mujeres los trastornos afectivos (13,8%, p 0,000), los de ansiedad (31,8%, p 0,000) y los trastornos de la personalidad (6,1%, p 0,000). Las patologías somáticas concomitantes diferenciales en las mujeres fueron las endocrino/metabólicas (45,3%, p 0,004), hematológicas (12,3%, p 0,016) y las alteraciones metabólicas agudas (15,6%, p 0,000).

 

Conclusiones: Los trastornos depresivos, de ansiedad y de la personalidad, en la Psiquiatría de Enlace e Interconsulta, son más prevalentes en las mujeres.  Las diferencias de género deben tenerse en cuenta a la hora de implementar una mejora en la identificación, prevención y tratamiento de los trastornos mentales.

Subjects: subject: Computer Science.

description: Detecting the position and the level of joint impingement is often a key to a computer-aided surgical plan to normalize joint kinematics. So far for ball-and-socket joints most of the existing impingement detection methods are not efficient or only consider the collided points as the detection result. In this thesis, we present two efficient and accurate collision detection systems to detect and evaluate the impingement on ball-and-socket joints. Through the first system, we rapidly non-uniformly sample the object surface in the spherical coordinate system based on polygon rasterization and then globally check the distance differences between the objects to approximately estimate the impingement level; the second system has a similar design but is based on a uniform sampling method which can sample the object more adequately and reduce the memory cost by 20%. We achieved the accuracy, the efficiency, and also the feature of providing overall impingement estimation and visualization on the joint surfaces. The first system is further applied in a real-time ROM observation simulation to flexibly check the location and the level of the impingement occurred during the motion.

Video indexing and summarization service for mobile users.

Subjects: subject: Engineering, Electronics and Electrical.

description: Image processing, video analysis and computer vision techniques are presently developing rapidly because of the availability of acquisition, processing and editing tools which use current hardware and software systems. However, problems still remain in conveying this video data to the end users. Limiting factors are the resource capabilities in distributed architectures, and the features of the users' terminals. The efficient use of image processing, video indexing, and analysis techniques can provide solutions or alternatives. This thesis presents a new algorithm for video segmentation, indexing and key framing tasks. The algorithm is based on color histograms, and uses a binary penetration technique. Although a lot of work has been done in this area, most does not adequately consider the optimization of timing performance and processing storage. This is especially the case when the techniques are designed for use within run-time distributed environments. A main contribution of this thesis is to blend high performance and storage criteria with the need for effective results. The algorithm uses the temporal heuristic characteristics of the visual information in a video stream. It considers the issues of detecting false cuts and missing true cuts due to the movement of the camera, the optical flow of large objects, or both. We discuss the merits of the new algorithm compared to the existing one, supporting the discussion both with results from experiments and from the implementation of our application. We also propose a video event modeling mechanism to intelligently parse, analyze and extract the significant content information from digital video libraries or video mails. This also requires an adaptation stage in order to react to the status, policies and configuration of the end user environment. In order to build robust and extendable systems capable of dealing with future new devices that may have new specifications, we consider devices by their characteristics rather than their type (PDA, PC, cellular phone, etc). We designed and developed a video key framing and summarization service within an overall agent-based architecture that negotiates the different factors autonomously and dynamically at run-time in order to provide the service to the user in an efficient and secure manner.

Photoacid generation and acid mobility: Mechanistic studies relevant to photolithography.
Creators: name: Coenjarts, Christopher.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2002
Subjects: subject: Chemistry, Physical.

description: Although highly varied, all of the work in this thesis involves studying acid in photolithographically relevant systems. The objectives of the individual projects never stray far from the central goal of acquiring mechanistic insight into both the photoacid generation process as well as acid mobility in polymer films. It is the ultimate goal of this work to gain a fundamental understanding of chemical processes and reaction mechanisms, in order to apply this knowledge to the evaluation and design of materials for use in photolithography. Techniques for quantifying and locating photogenerated acid in solution and in polymer films were both developed and extensively employed. These techniques are based on the protonation of acid-sensitive dyes and were used for the purposes of studying acid diffusion as well as evaluating photoacid generating efficiencies of photoacid generators (PAGs). A novel technique for monitoring acid desorption from polymer films was developed in order to study the behaviour of acid in polymer films under processing conditions similar to those employed industrially. The kinetics for acid desorption were measured and the factors which control acid mobility were identified. Much of the work presented in this thesis is focused on determining the mechanisms by which PAGs generate acid as well as designing and testing new molecules for use as PAGs. Among the molecules studied in these contexts were sulfones, N-heteroaromatic salts and sulfonium salts tethered to ketones. The key steps towards photoacid generation for these molecules include homolytic bond cleavage, photoinduced electron transfer and triplet energy transfer, respectively.

description: Background: Family medicine (FM) residents choose among a range of options as they enter practice, including practice model, clinical domains, settings, and populations. The choices they make have implications for primary care workforce planning and may differ between FM residents who are parents and those who are not, as well as between male and female FM residents. We investigate whether parenthood shapes intentions among FM residents entering practice and whether the effect of parenthood differs between male and female FM residents. Methods: We conducted cross-sectional analysis of national survey data collected from FM residents in Canadian residency programs by the College of Family Physicians of Canada between 2014 and 2017. The survey captures information on intentions for comprehensive or focused practice, practice model, clinical domains, practice setting, and populations. We used chi-square tests and multivariable logistic regression to investigate the relationships between parenthood, gender, and practice intentions, adjusting for other physician personal characteristics. Results: Almost a quarter of FM residents were parents or became parents during residency. Intentions for the provision comprehensive care were higher among parents, and intentions for clinically focused practice were lower. Differences in intentions for practice models, domains, and settings/population were primarily by gender, though in several cases the effects of parenthood differed between female and male FM residents. Even during residency, the effects of parenthood differ between male and female residents: while three quarters of male parents finish residency in two years, fewer than half of female parents do. Conclusions: Both parenthood and gender independently shape practice intentions, but the effect of parenthood differs for male and female FM residents. Supporting FM residents who are parents may positively impact the quality and availability of primary care services, especially since parents are more likely to report intentions to provide  comprehensive care soon after entering practice.

description: Abstract

Cigarette smoking and exposure to cigarette smoke during pregnancy have detrimental effects on the health of expectant mothers, increasing the likelihood of respiratory diseases or infections. Due to the stimulant effect of smoking, the negative effect on diurnal rhythm and sleep is also observed. Sleep quantity and quality are directly related to health and well-being, especially during times of excess stress, such as the perinatal period. This prospective study aimed to examine the relationship between cigarette smoking and exposure to cigarette smoke during pregnancy and sleep patterns in pregnant women. An online survey was conducted among Polish women from May 2020 to September 2021, during the COVID-19 pandemic. Participants reported the use of stimulants during pregnancy and rated sleep in three categories (difficulty falling asleep, waking up too early, and difficulty staying asleep). Data from 3365 mothers aged 18-43 (mean 30.7; SD 3.87) were analyzed using multivariate logistic regression. The incidence of sleep problems in pregnant women was shown to be associated with exposure to cigarette smoke (passive smoking) while controlling for a range of individual variables (age, education, place of residence, satisfaction with the woman's life, and economic situation, pregnancy complications, levels of state anxiety and depressive symptoms, trimester of pregnancy, nausea or vomiting during pregnancy, and COVID-19 infections). Interestingly, active smoking was not associated with sleep difficulties. Our results suggest that passive smoking is a potential risk factor for sleeping problems in pregnant women, especially in the aspect of waking up too early. These results are worth considering when formulating pro-health measures for pregnant women and their close ones.
Pornography as a subject for religious studies: New directions for the field of women and religion.
Creators: name: Downing, Marymay.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1994
Subjects: subject: Religion, General.

description: The argument of this thesis is that pornography is a subject relevant for religious studies, particularly for the sub-field of women and religion. A review of the etymological derivation and history of the word 'pornography', and of various positions in the current definitional debate, provide the basis for defining the term. Methodologically, the thesis approach is feminist because it engages with feminist theory in religion and proceeds from the premise that pornography is experienced by the majority of women as a "problem" in need of analysis. Only a few religious studies scholars have treated the subject previously; their ideas are outlined and critically assessed. Chapter Two examines the history of modern pornography's self-conscious relation of antithesis with Christianity, beginning with pornographic literature of the late 18th century and including contemporary pornographic books and magazines. A third demonstration of pornography's relevance is presented in Chapter Three by means of analyses of several feminist critiques of pornography, each of which asserts significant correspondences between pornography and the Christian religion. Chapter Four proposes that newly developing theory about gender-based differences in experiences of the sacred is supported by an analysis of women's objections to pornography. Finally, by analyzing the abstract features of pornography's content and form, the argument is presented in Chapter Five that pornography can be seen to be functioning like a religion in contemporary society. Its meaningfulness, contrary to most expectations, can be compared to multivalent religious myths and symbols. The argument concludes by noting that pornography is a relevant subject for religious studies not only because it contributes to these various aspects of theory in the study of religion, especially in the field of women and religion, but also because the discipline of religious studies offers a particularly useful perspective on the problem of pornography. By elucidating more fully the nature of pornography in its contemporary manifestations, including the manner in which it can be seen to be functioning as a replacement for religion in modern society, a religious studies perspective helps to explain why pornography should be recognized as a problem of significant dimensions that merits more serious attention and efforts at resolution.

description: Le concept moderne du risque, definit maintenant comme un danger est invoque pour proteger l'individu de la menace du sida. En effet la seule facon de proteger la societe est en invoquant la menace individuelle. Etant percu comme une maladie resultant des choix des acteurs individuels, le sida exige des solutions de la meme nature pour enrayer sa dissemination. Considerer l'epidemie du HIV comme un probleme de comportement a risque semble avoir renforce la culture individualiste de la societe industrielle occidentale. Impregnee des stereotypes moralisateurs, du la definition sociale du sida formulee en Occident evoque la notion de responsabilite individuelle. C'est l'individu qui est coupable d'avoir contracte le HIV. Devenue une realite en soi et maintenant universalisee, cette definition de l'epidemie du HIV s'est vue refletee, non seulement dans la facon dont est vue cette problematique ailleurs, tel que dans le Tiers Monde, mais aussi, dans les solutions proposees. Celles-ci contrastent souvent avec les realities des pays du Tiers Monde. (Abstract shortened by UMI.)

The role of self-construals in obsessive-compulsive disorder
Creators: name: Ahern, Claire Terese
Publisher: name: Swinburne

description: Our sense of self is central to how we experience the world and provides an important foundation with which to understand psychological health. This thesis examined the role of self-contruals in Obsessive-Compulsive Disorder, a highly debilitating anxiety disorder considered to be amongst the most common and disabling psychiatric conditions. With the use of questionnaire, interview and computer based experiments, results on 140 volunteers demonstrated that self-processes are involved in both the development and maintenance of Obsessive- Compulsive Disorder. These findings are important because they increase our theoretical understanding of Obsessive-Compulsive Disorder, and suggest ways that we may improve patient adherence and outcomes of psychological treatment.
Low density lipoprotein receptor: Interaction with ligands and molecular chaperone proteins.

Publisher: name: Université d'Ottawa / University of Ottawa

description: The low density lipoprotein receptor (LDLr) is a complex multi-domain protein that is involved in the maintenance of cholesterol homeostasis. To study the kinetics of interaction of lipoproteins to the LDLr, we produced truncated forms of the LDLr that included the ligand-binding domain with and without the EGF homology domain. In the absence of the EGF precursor homology domain the receptor was secreted from Chinese hamster ovary (CHO-K1) cells as inactive, disulfide-linked multimers. In contrast, in the presence of the EGF precursor homology domain the receptor was secreted as a functional monomeric species. These observations led us to believe that inter-domain interactions may be involved in producing an active receptor. Since many mutations that cause familial hypercholesterolemia (FH) map to the EGF precursor homology domain, we expressed the EGF precursor homology domain as a separate polypeptide in order to determine if it could act in trans to assist in the proper folding of the ligand-binding domain. We propose a model, whereby an initial co-translational stabilization of the ligand-binding domain by chaperone proteins is followed by a post-translational interaction of the EGF repeats with the ligand-binding domain to yield a properly folded and functional receptor. Low density lipoproteins (LDL) are heterogeneous in terms of size, lipid composition and protein conformation. These factors influence the ability of LDL to bind to the LDLr. The binding of lipoproteins to the LDLr is also modulated by a number of other factors including ligand conformation, cell surface proteoglycans and steric hindrance. Surface plasmon resonance (SPR) was used to determine the affinity and kinetics of the LDL-LDLr interaction. This technology allows for interactions to be continuously monitored in real time and generates binding profiles from which rate constants can be derived. To minimize lattice effects and to exclude the participation of other cell surface components, a soluble N-terminal 692 amino acid LDLr fragment was stably produced in mammalian cells. The LDLr was expressed at 10 mug/ml and could be immuno-purified to homogeneity using the anti-LDLr monoclonal antibody, C7. The LDLr bound biotinylated LDL on a ligand blot and, when monitored by SPR, it could bind native but not acetylated LDL, which demonstrates its physiological specificity. The kinetics of binding fit a model in which a conformational change in the receptor and/or the ligand occurs following the initial binding that converts a low affinity complex to a high affinity complex with a slow dissociation rate. To determine the effect of LDL heterogeneity on the kinetics of binding, LDL from hypertriglyceridemic patients was tested. The small, dense and triglyceride-enriched particles bound the LDLr with similar conformational kinetics as native LDL.

description: High calorie intake has proved harmful worldwide, as it has led to many diseases. However, dieticians have deemed that a standard intake of number of calories is essential to maintain the right balance of calorie content in human body. In this thesis, we consider the category of tools that use image processing to recognize single and multiple mixed-food objects, namely Deep Learning and the Support Vector Machine (SVM). We propose a method for the fully automatic and user-friendly calibration of the sizes of food portions. This calibration is required to estimate the total number of calories in food portions. In this work, to compute the number of calories in the food object, we go beyond the finger-based calorie calibration method that has been used in the past, by automatically measuring the distance between the user and the food object. We implement a block resize method that uses the measured distance values along with the recognized food object name to further estimate calories. While measuring distance, the system also assists the user in real time to capture an image that enables the quick and accurate calculation of the number of calories in the food object. The experimental results showed that our method, which uses deep learning to analyze food objects, led to an improvement of 16.58% in terms of recognition, over the SVM-based method. Moreover, the block resize method showed that percentage error for calorie estimation was reduced to 3.64% as compared to 5% achieved in previous methods.

description: Les concentrateurs photovoltaïques sont parmi les technologies d'énergies solaires les plus prometteuses. Ils ont une efficacité allant jusqu'à deux fois celle des panneaux photovoltaïques conventionnels. Malgré les avancements en recherche et développement, les concentrateurs photovoltaïques demeurent des systèmes relativement complexes. Cette même complexité laisse place à l'innovation et à la possibilité de réduire considérablement les coûts de fabrication. Dans le cadre de cette thèse, deux sites de tests sont développés et déployés pour faire l'analyse des performances des concentrateurs photovoltaïques plats. Quatre designs de cellules solaires sont caractérisés en laboratoire et incorporés dans les panneaux prototypes pour ensuite être individuellement étudiés. Les quatre designs sont ensuite comparés l'un à l'autre, et selon leurs emplacements, pour comprendre comment le design de la cellule affecte la performance des panneaux.

description: Objective: Type I interferons (IFN) have important roles in many immune-mediated inflammatory diseases (IMIDs) and are a relatively new therapeutic target. Direct detection of type I IFNs has proved challenging, thus their presence is often inferred from the expression of interferon-stimulated genes (ISGs) and calculation of an interferon score (IS). The objective of this research was to determine if the expression of six common ISGs and subsequent IS were comparable when RNA was derived from the Tempus and PAXgene whole blood RNA collection systems. Results: Whole blood was obtained from ten healthy adults, incubated ex vivo in the absence and presence of recombinant human IFNα then divided into PAXgene and Tempus tubes. Despite reports of tube-specific patterns of gene expression, quantitative PCR (qPCR) analysis revealed no significant differences between PAXgene and Tempus tubes in either the homeostatic or IFNα-induced expression of six ISGs (IFI27, IFI44L, IFIT1, ISG15, RSAD2, SIGLEC1). Overall there was a strong correlation in the IS between unstimulated (r = 0.92, p = 0.0005) and IFNα-stimulated (r = 0.71, p = 0.0268) samples derived from the PAXgene and Tempus tubes.

description: Canada coordinates its responses to natural disasters abroad through implementing its ‘whole-of-government’ policy framework. The two largest natural disasters that struck in 2010 were the January earthquake in Haiti and the flooding in Pakistan seven months later. In contrast to the fast and robust earthquake relief provided to Haiti, Canada’s response to the Pakistan floods was minimal, especially when considering the extent of damage sustained. This dissertation applies a public administration lens to trace factors that led to the Government of Canada’s 2010 disaster-relief decisions. It develops a multi-level theoretical framework to holistically explore the role of problem-definition in shaping decision-making. It applies historical institutionalism at the macro level; recognizes the role of case-specific details and arenas at the meso level; and uses the logic of appropriateness to identify informal institutions affecting individual action at the micro level. Analysis of interviews, government documents and media coverage indicates that bureaucratic actors involved in the whole-of-government approach recognize that their role is ultimately removed from final disaster-relief decisions. There is an informal acceptance that political will, more than needs in the disaster-affected region, shapes implementation decisions. Consequently, technical assessment is inadvertently affected, and recommendations reflect what is deemed most in line with ministerial disposition to assist. The primary motivators for Government of Canada action are found to be the gaining of public support or the need to subdue targeted criticisms. Findings indicate that as a result of its media appeal, there was a strong incentive for the deployment of military assets in response to the earthquake in Haiti, even when doing so was not in the best interest of the affected region. Where Canada could respond only with non-military means, there was less incentive for action. This leads to supply-driven relief rather than a needs-based humanitarian response. With the developed theoretical framework, process-mapping and media analysis methodologies, and the actor-centred approach adopted, the dissertation makes theoretical and empirical contributions to existing public administration literature on decision-making and problem definition. It also presents a hitherto unexplored perspective on donor behaviour for consideration by international relations and development scholars.

description: During the past years, there has been an increasing interest in the design and development of network traffic controllers capable of ensuring the QoS requirements of a wide range of applications. In this thesis, based on previous work, we use a systems approach to construct a dynamic model for the token bucket mechanism: a traffic controller widely used in various QoS-aware protocol architectures. An enhanced model of multiplexor is also added into the multiple token buckets system model. In this way, the model represents a complete system at the access node of the network. We then develop an optimization algorithm based on a dynamic programming and genetic algorithm approach. Applying two MPEG-1 video traces and two self-similar traffic traces, we conduct an extensive campaign of numerical experiments allowing us to gain insight into the operation of the controller and evaluate the benefits of using a genetic algorithm approach to speed up the computation process based on dynamic programming. Our results show that the optimization is not only capable of getting the best cost, but also balancing the costs corresponding to different aspects. The results also shows that the use of the genetic algorithm proves particular useful in reducing the computation time required to optimize the operation of a system consisting of multiple token-bucket regulated sources.

description: The aim of EKLIPSE is to develop a mechanism to inform European-scale policy on biodiversity and related environmental challenges. This paper considers two fundamental aspects of the decision-support mechanism being developed by EKLIPSE: 1) the engagement of relevant actors from science, policy and society to jointly identify evidence for decision making; and 2) the networking of scientists and other holders of knowledge on biodiversity and other relevant evidence. The mechanism being developed has the potential not only to build communities of knowledge holders but to build informal networks among those with similar interests in evidence, be they those that seek to use evidence or those who are building evidence, or both. EKLIPSE has been successful in linking these people and in contributing to building informal networks of requesters of evidence, and experts of evidence and its synthesis. We have yet to see, however, significant engagement of formal networks of knowledge holders. Future success, however, relies on the continued involvement with and engagement of networks, a high degree of transparency within the processes and a high flexibility of structures to adapt to different requirements that arise with the broad range of requests to and activities of EKLIPSE.

description: The introduction of Professional Standards legislation across Australia in 2003 reinforced a requirement of professional associations that professionals undertake professional development in order to maintain and enhance their knowledge. A case study of small/medium accounting enterprises determined that Professional Standards legislation had no impact on the way professional development is conducted. The research identified: a) the substantial benefits to professional enterprises generated by professional development; b) enterprises invest considerable time and money in professional development; and c) the factors influencing the outcomes. Greater understanding of professional development potentially increases the knowledge held and available to the public.

Novel lamin AC mutations and their expression in the cardiac tissue of end-stage dilated cardiomyopathy patients

Subjects: subject: Biology, Genetics.

description: Dilated cardiomyopathy (DCM) is a cardiac muscle disorder characterized by ventricular dilatation and impaired systolic function. LMNA, one of fifteen autosomal genes implicated in this disease, encodes for two alternatively spliced nuclear intermediate filaments proteins, lamins A and C. Two novel missense mutations, D192G and R541 S, were identified in highly conserved regions of the LMNA gene. Electron micrographs of cardiac tissue containing the D192G mutation demonstrated dramatic morphologic alterations of the nucleus. By contrast, cardiac samples from the R541 S carrier were almost indistinguishable from those of transplanted DCM patients without LMNA mutations. Expression levels of total LMNA mRNA in this individual were comparable to those found in end-stage DCM patients without LMNA mutations. Moreover, the mutated allele was expressed in the heart tissue of this patient. Functional studies to determine the impact of these mutations on cellular models are ongoing.

description: Abstract To explore the largely unknown etiology of small intestine cancer, we examined metabolic factors and risk of small intestine cancer overall and by subtypes. Among 404 220 women and 403 265 men in six European cohorts, we applied Cox regression with adjustment for smoking and body mass index (BMI), to calculate sex‐specific hazard ratios (HRs) of small intestine cancer by levels of BMI, mean arterial pressure (MAP) and plasma total cholesterol, triglycerides and glucose. We also calculated HRs for these factors combined (metabolic score; MetS) and used Wald test statistics to investigate pairwise interactions between metabolic factors on risk. We also performed analyses separately per subtype (neuroendocrine tumors [NETs] and adenocarcinomas). During a median follow‐up of 16.9 years, 144 women and 195 men were diagnosed with small intestine cancer, including 184 NETs and 99 adenocarcinomas. Among men, no main associations or interactions between metabolic factors were observed in relation to the risk of small intestine cancer. Among women, triglycerides were positively and linearly associated with risk (HR per standard deviation [SD]: 1.23, 95% confidence interval [CI]: 1.04‐1.46), and a positive association was also observed for the MetS (HR per SD: 1.25, 95% CI: 1.02‐1.52). Positive interactions were observed among women between triglycerides and cholesterol (P = .0005), and between MAP and glucose (P = .009), on risk. Glucose was positively associated with adenocarcinomas among women. This large, prospective study suggests that elevated triglycerides, and metabolic factors in interaction, confer an increased risk of small intestine cancer among women, but not among men.
