Bakgrund: Dysfagi innebär avvikelser i den normala sväljningsfunktionen och är en vanlig funktionsnedsättning till följd av stroke. Tidigare studier har påvisat att incidensen av dysfagi i det akuta skedet efter stroke är 41-68 %. Kliniskt sett upplevs incidensen ha minskat de senaste tio åren. Syfte: Syftet med denna studie var därför att (1) undersöka den nuvarande incidensen av orofaryngeal dysfagi hos nyinsjuknade strokepatienter, (2) undersöka hur många av deltagarna som upplever svårigheter att äta och svälja samt bedöms lida av dysfagi enligt vårdpersonal. Metod: Sextiotre patienter inkluderades i studien, av dessa fick 42,9 % diagnosen stroke. Samtliga deltagare genomgick en dysfagibedömning inom tre dygn efter inskrivning på vårdavdelning. Denna bestod av testerna the Standardized Swallowing Assessment – Svensk översättning (SSA-S) och sväljkapacitetstest (SCT). Deltagare som inte klarade kriterierna i dessa bedömdes lida av orofaryngeal dysfagi. Resultat: Totalt bedömdes 24 deltagare lida av orofaryngeal dysfagi. I diagnosgruppen stroke var incidensen 48,1 %. Det fanns noteringar om dysfagi i patientjournal hos 20,8 % av deltagarna som enligt testledare bedömdes lida av orofaryngeal dysfagi. Vidare upplevde 29,2 % av samtliga deltagare med orofaryngeal dysfagi samt 30,8 % i diagnosgruppen stroke svårigheter att äta eller svälja. Slutsatser: Studien indikerar på att incidensen av orofaryngeal dysfagi hos nyinsjuknade strokepatienter inte har minskat i jämförelse med tidigare studier. Däremot tycks det finnas en låg medvetenhet om befintliga ät- och sväljningssvårigheter hos såväl patienter som vårdpersonal.Background: Dysphagia involves abnormalities in the normal swallowing function, and is a common impairment following stroke. Previous studies have shown that the incidence of dysphagia in the acute phase after stroke is 41-68 %. Clinically interprets that the incidence has declined over the past decade. Aim: The purpose of this study was to (1) examine the current incidence of oropharyngeal dysphagia in recent-onset stroke patients, (2) investigate how many of the participants who experience difficulty eating and swallowing, and how many is believed to suffer from dysphagia according to healthcare professionals. Method: Sixty-three patients were enrolled in the study, of whom 42,9 % were diagnosed with stroke. All participants underwent a bedside assessment of swallowing function within three days after enrollment in the nursing ward. The assessment consisted of the Standardized Swallowing Assessment - Swedish translation (SSA-S) and swallowing capacity test (SCT). Participants who did not pass the criteria of these two tests suffered from oropharyngeal dysphagia. Results: Totally, 24 participants suffered from oropharyngeal dysphagia. The incidence in the stroke group was 48,1 %. There were notes about dysphagia in medical records in 20,8 % of the participants who were judged to suffer from oropharyngeal dysphagia by the test managers. Furthermore 29,2 % of all participants with oropharyngeal dysphagia and 30,8 % in the stroke group experienced difficulty eating or swallowing. Conclusions: This study indicates that the incidence of oropharyngeal dysphagia in recent-onset stroke patients has not decreased in comparison with previous studies. In contrast, it appears to be a low awareness of existing eating and swallowing difficulties for both patients and healthcare professionals.

In this thesis stochastic techniques are used in attempts to understand cancer risk, its relationship to patient age and genotype, as well as its distribution in human populations. The starting point for the thesis is the general observation that cancer incidence grows in approximate proportion to an integer power of age. Quasi-mechanistic mathematical models of cancer incidence have suggested that the integer power in a given case is related to the number of crucial cellular events that must occur for a malignant tumour to evolve from a healthy tissue. This idea and its limitations are explored. Further applications of cancer incidence models are then evaluated and developed. Specifically, a critical examination is presented of the notion that increases in risk associated with a particular predisposing germline gene mutation, can provide information about the disease-associated activity of that gene. Finally, there is a discussion of heterogeneity in liability to cancer. Methods for quantifying this heterogeneity and its effect on incidence patterns are investigated.

An element \(\char{cmti10}{0x78}\) of a Lie algebra \(\char{cmmi10}{0x4c}\) over the field \(\char{cmmi10}{0x46}\) is extremal if [\(\char{cmti10}{0x78}\), [\(\char{cmti10}{0x78}\), \(\char{cmmi10}{0x4c}\)]] \(\subseteq\)\(\char{cmmi10}{0x46}\)\(\char{cmti10}{0x78}\). One can define the extremal geometry of \(\char{cmmi10}{0x4c}\) whose points \(\char{cmsy10}{0x45}\) are the projective points of extremal elements and lines \(\char{cmsy10}{0x46}\) are projective lines all of whose points belong to \(\char{cmsy10}{0x45}\). We prove that any finite dimensional simple Lie algebra \(\char{cmmi10}{0x4c}\) is a classical Lie algebra of type A\(_n\) if it satisfies the following properties: \(\char{cmmi10}{0x4c}\) contains no elements \(\char{cmti10}{0x78}\) such that [\(\char{cmti10}{0x78}\), [\(\char{cmti10}{0x78}\), \(\char{cmmi10}{0x4c}\)]] = 0, \(\char{cmmi10}{0x4c}\) is generated by its extremal elements and the extremal geometry \(\char{cmsy10}{0x45}\) of \(\char{cmmi10}{0x4c}\) is a root shadow space of type A\(_{n,(1,n)}\).

Pełny tekst źródłaStreszczenie:
This thesis is concerned with developing and implementing a method for modelling and projecting cancer incidence data. The burden of cancer is an increasing problem for society and therefore, the ability to analyse and predict trends in large scale populations is vital. These predictions based on incidence and mortality data collected by cancer registries, can be used for estimation of current and future rates, which is helpful for public health planning. A large body of work already exists on the use of various modelling strategies, methods and fitting techniques. A multilevel method of preparing the data is proposed, fitted to historical data using regression modelling, to predict future rates of incidence for a given population. The proposed model starts with a model for the total incidence of the population, with each successive level stratifying the data into progressively more specific groupings, based on age. Each grouping is partitioned into subgroups, and each subgroup is expressed as a proportion of the parent group. Models are fitted to each of the proportional age-groups, and a combination of these models produces a model that predicts incidence for a specific age. A simple, efficient implementation of the modelling procedure is described, including key algorithms and measures of performance. The method is applied to data from populations that have very different melanoma incidence (the USA and Australia). The proportional structure reveals that the proportional age trends present in both populations are remarkably similar, indicating that there are links between causative factors in both populations. The method is applied fully to data from a variety of populations, and compared with results from existing models. The method is shown to be able to produce results that are reliable and stable, and are generally significantly more accurate than those of other models.

Background: Amyloidosis is a rare disorder of protein folding in which a variety of proteins deposit as fibrils in the extracellular space. The two most commonly affected organs are the kidneys and heart. Deposition of amyloid in these two critical organs is of major prognostic importance. Aims: To identify the burden of systemic amyloidosis in the English population. To characterise the phenotype and diagnostic features of wild type transthyretin amyloidosis and identify the type and frequency of arrhythmic activity in cardiac amyloidosis. To evaluate outcome in renal amyloidosis, and assess the role of renal replacement therapy. Results and Conclusions: Amyloidosis was mentioned in 0.58/1000 deaths in England between 2000 and 2008. Sensitivity of death certificates in identifying patients with amyloidosis was 79%. The estimated true incidence of the disease is ~1/100000 population in England. Wild type transthyretin amyloidosis (ATTRwt) is increasingly diagnosed in the UK. Age of the patient at diagnosis and N T-proB N P level can aid in distinguishing ATTRwt from cardiac AL amyloidosis. Median survival is significantly better in ATTRwt than in cardiac AL amyloidosis. A positive troponin T, a pacemaker and NYHA class IV symptoms are all associated with worse outcome. Complex ventricular arrhythmias are seen more frequently on Holter monitoring in patients with transthyretin cardiac amyloidosis compared to cardiac AL which are in turn more frequent than patients without myocardial amyloid infiltration. There does not appear to be an association between the frequency of complex ventricular arrhythmi as and disease severity in cardiac amyl oi dosi s. Renal and overall outcome in AL amyl oi dosi s are both strongly associated with FLC response and are best among patients who achieve >90% suppression of the monoclonal component of the FLC. Survival on dialysis is improving. Outcome following renal transplantation is dependent on the amyloid fibril type and suppression of the precursor protein.

The incidence structure of the cross-polytope gives rise to certain modular representations for the hyperoctahedral group. In this thesis we introduce and begin the study of these natural representations. In particular we show that they satisfy a branching rule. This branching rule is used to extract information about the representations and underlying combinatorial objects. Amongst the information extracted is a formula for the dimensions of the representations. This has applications in calculating the p-rank of incidence matrices arising from the cross-polytope. We also construct explicit generators for the representations and identify cases where the representations are irreducible.

This study compared the cost-effectiveness of four tuberculosis (TB) control strategies for detecting and treating latent tuberculosis infection (LTBI) among long-term travellers to countries where TB incidence is elevated. The decision analysis considered hypothetical cohorts of travellers from Canada and the United States (U.S.) to Mexico, Haiti, and the Dominican Republic. Strategy I consisted of screening for incident infection via two-step tuberculin skin testing prior to travel and skin testing upon return from abroad, followed by standard LTBI treatment with isoniazid for skin test converters. Strategy II carried the additional recommendation of isoniazid treatment for individuals who screen positive for LTBI before travel. Strategy III consisted of post-travel tuberculin skin testing alone, and isoniazid for all reactors. Strategy IV consisted of post-travel chest radiographic screening alone, and LTBI treatment for travellers with inactive TB. All strategies were compared with the status quo strategy of passive case detection. Costs were assessed from the viewpoint of the health system, in year 2003 Canadian dollars, and effectiveness was measured as cases of active TB prevented. In the base analysis, travel duration was 3 months. Strategy III (the single post-trip tuberculin test) was most effective in reducing future incidence of active TB, with the lowest incremental cost per TB case prevented. The best candidates for TB screening were travellers born in Haiti who visited Haiti, for whom Strategy III cost an estimated $37,613 per TB case prevented. Even for this group, however, no net cost-savings resulted from any screening strategy.

This research encompasses four studies exploring bone adaptation, fracture incidence, and preventative measures to decrease fracture risk and increase bone health. Study one was a clinical audit exploring incidence rates for appendicular fractures in children in Western Australia over ten years. Diagnostic and remedial approaches were explored in studies two, three and four by examining the between-day reliability of upper limb scans; reliability of the osteogenic index (OI) for upper-body strength and power exercises; and the diagnostic value or utility of using pQCT in disease profiling, respectively. Fracture rates in the limbs of children were found to be increasing each year, particularly in the forearm, and regardless of gender, between 2005 and 2015, similar to international trend data. pQCT was established as a reliable tool for quantifying upper limb diaphyseal measurements. The OI had varying reliability depending on the equation used, exercise type and exercise intensity when measured using accelerometers at multiple locations. Lastly, paediatric populations with low motor competence and/or neuromuscular disorders were disease profiles which had a measurably negative influence on bone when compared to unaffected controls. The increase in fracture incidence in Western Australia is a concerning trend for bone health in children and adolescents that requires lifestyle and population-based interventions to arrest this incremental problem. pQCT may be a valuable tool for disease profiling with area measurements for bone and some muscle variables more reliable than volumetric measurements in the upper limbs. The OI is a more reliable tool when measuring strength exercises than power exercises; and individuals with a greater risk of weaker bones should apply more daily load to increase their overall bone health. Interventions should be put into place to rehabilitate individuals with already weaker bones, such as targeted and well-designed exercise programs supported by good nutritional practices.

L'intérêt du programme de dépistage du cancer du sein par mammographie résulte de la balance entre la réduction de la mortalité et les effets indésirables du programme. L'objectif de ce travail était d'évaluer trois aspects du programme de dépistage dans le département de l'Isère. Nous avons utilisé une méthode Approximate Bayesian Computation pour estimer le surdiagnostic lié au dépistage par mammographie de cancers non évolutifs. Ils représentaient respectivement 1,5% (IC95% : 0,3% - 2,9%) et 28,0% (IC95% : 2,2% - 59,8%) des cancers invasifs et in situ diagnostiqués. Nous avons réalisé une revue de la littérature des méthodes d'estimation du surdiagnostic et montré sur des données simulées que les méthodes basées sur les taux d'incidence annuels étaient les moins sensibles aux biais. Par ailleurs, l'incidence des cancers de l'intervalle était inférieure lorsque les mammographies étaient réalisées avec deux clichés par sein au lieu d'un seul, aussi bien à 12 que à 24 mois. Enfin, l'exclusion du diagnostic de cancer après la réalisation d'une imagerie supplémentaire, d'une biopsie ou un suivi radiologique diminuait la participation lors de la prochaine invitation au dépistage organisé. En conclusion, l'intérêt du programme de dépistage du cancer du sein par mammographie n'est pas remis en cause avec 1,4 décès évité pour un cancer surdiagnostiqué (in situ ou invasif).

Many women experience miscarriage every year. Every fourth woman who has given birth reports that she has previous experience of miscarriage. In a study of all women in the Swedish Medical Birth Register 1983-2003, we found that the number of cases of self reported miscarriage had increased in Sweden during this 21 year period. This increase can be explained by the introduction of sensitive pregnancy tests around 1990, as well as an increase in the mean age of the mothers, by approximately 3 years, during the observation period. The risk of miscarriage is 13% with the first child. With subsequent pregnancies, the risk of miscarriage is 8%, 6% and 4% with the second, third and fourth child, respectively. Thirteen of these women who had suffered a recent miscarriage were interviewed four months later, and their feelings of guilt and emptiness were explored. Their experience was that they wanted their questions to be answered, and that they wanted others to treat them as the mothers to be that they felt themselves to be. They also experienced the need for time to grieve their loss. Measurement of grief by means of the Perinatal Grief Scale (PGS) is used in research but has also been proposed for clinical use. We have translated this psychological instrument to Swedish, back-translated and tested it in a small pilot study. In a randomized controlled study, women with early miscarriage were allocated, either to a structured visit (study group) or a regular visit (control group) to a midwife. The structured visit was conducted according to the Swanson caring theory. We could conclude that the structured visit had no significant effect on grief compared to the regular visit, as measured using the PGS. However, women with the sub-diagnosis missed abortion have significantly more grief four months after early miscarriage, regardless of visit type. We also performed a content analysis of the tape-recorded structured follow-up visit. The code-key used was Bonanno and Kaltman’s general grief categorization. Women’s expression of grief after miscarriage was found to be very similar to the grief experienced following the death of a relative. Furthermore, the grief was found to be independent of number of children, women’s age, or earlier experience of miscarriage. Conclusions: Every fourth woman who gives birth reports that she has also experienced early miscarriage. The experience of these women is that they have suffered a substantial loss and their reaction is grief similar to that experienced following the death of a relative.On the day of the public defence of the doctoral thesis the status of article III was In Press and article IV was In Press.

Temporomandibular disorders (TMD) embrace pain and dysfunction in the temporomandibular joint (TMJ) and jaw muscles. TMD is a prevalent condition in the population and constitutes a significant health problem. Knowledge of factors influencing the onset and course of TMD is important in preventive care and development of treatment strategies as well as in clinical decision making. The aim of this thesis was to gain knowledge of whether variations in dental occlusion, bruxism, spinal pain and gender predicted the development and course of TMD. The study population comprised 371 undergraduate dental students. A questionnaire was used to obtain case histories. Clinical examination included the function of the TMJ, jaw muscles, maximal jaw mobility, the morphological occlusion, and contact patterns in centric and eccentric positions. The examinations were performed at start, and after 12 and 24 months. In total, 280 subjects were examined at all three occasions. The incidence of TMJ pain and dysfunction was high among both males and females. The course composed onset, recovery and maintenance resulting in a fluctuating pattern. Females were more likely to have persistent TMJ pain and dysfunction than males. The incidence and persistence of jaw muscle signs and symptoms was high and significantly more common in females. A similar fluctuating pattern as for TMJ pain and dysfunction was found. Crossbite predicted onset and persistence of TMJ pain and dysfunction; mandibular instability in centric positions predicted persistent TMJ pain and dysfunction, as well as persistent jaw muscle signs or symptoms. Reported bruxism increased the risk for TMJ pain and dysfunction but did not significantly affect the course of jaw muscle signs and symptoms. Spinal pain at baseline predicted the onset of jaw pain, headaches, and TMD pain. Signs of TMD at baseline predicted the onset of non-pain symptoms of TMD, jaw pain, headaches, and spinal pain. In conclusion, the results in this thesis show high incidence rates for TMD, headaches, and spinal pain among dental students. Crossbite, mandibular instability, reported bruxism, as well as female gender were identified as contributing risk factors. Spinal pain and TMD mutually predicted each other, indicating common pathophysiological mechanisms and individual vulnerability. The findings support a multidisciplinary approach, and it is recommended that the status and function of the jaw system be considered in patients with spinal pain.

If diseased plants (or plant units) are randomly dispersed, the frequency distribution of diseased plants (or plant units) per sample may be described by a binomial distribution, and statistical analyses may be based on the linear logistic model. Since most disease incidence data do not have a random spatial pattern, the binomial distribution can hardly ever, in practice, be used to describe observed frequencies. In this study, the use of conditional probability distributions, such as the logistic-normal binomial distribution, for such data is illustrated. Both descriptive distribution fitting and statistical modelling are discussed. The study evaluates several methods for analysis of incidence data which do not exhibit a random spatial pattern. Some of these methods are applied to plant disease data for the first time. A method of choosing between the different analyses is discussed. All the techniques are illustrated using examples and, as an application, survey data collected on pineapple wilt disease in Sri Lanka are extensively studied. As an alternative method of describing disease incidence data with a non random spatial pattern, the use of two-dimensional distance class (2DCLASS) analysis was evaluated using the same survey data. 2DCLASS analysis is widely accepted in plant disease epidemiology as a method of analysing non-random spatial patterns when the observations are made as presence or absence of the disease on individual plant basis. We demonstrate the possibility of using quadrat-based data in 2DCLASS analysis. We investigate the use of 2DCLASS analysis as a methodology and find some drawbacks with this technique, which are discussed in detail. Moreover, this study introduces a new parameter in the 2DCLASS analysis called Scaled Core Cluster size, that may be more suitable to use for comparison of datasets of different sizes.

Pełny tekst źródłaStreszczenie:
Research on road safety has been of great interest to engineers and planners for decades. Regardless of modeling techniques, a serious factor of inaccuracy - in most past studies - has been data aggregation. Nowadays, most freeways are equipped with continuous surveillance systems making disaggregate traffic data readily available ; these have been used in few studies. In this context, the main objective of this dissertation is to capitalize highway traffic data collected on a real-time basis at the moment of accident occurrence in order to expand previous road safety work and to highlight potential further applications. To this end, we first examine the effects of various traffic parameters on type of road crash as well as on the injury level sustained by vehicle occupants involved in accidents, while controlling for environmental and geometric factors. Probit models are specified on 4-years of data from the A4-A86 highway section in the Ile-de -France region, France. Empirical findings indicate that crash type can almost exclusively be defined by the prevailing traffic conditions shortly before its occurrence. Increased traffic volume is found to have a consistently positive effect on severity, while speed has a differential effect on severity depending on flow conditions. We then establish a conceptual framework for incident management applications using real-time traffic data on urban freeways.

Background: Professional ballet dancers focus on the high levels of discipline, perfection and mobility to achieve the fluid, controlled lines of movement presented on the stage. Dancers undergo long hours of strenuous, repetitive training which increases the risk of developing overuse or traumatic injuries and may compromise the longevity of dancers' careers. Relevant research, particularly in the South African context, is needed to provide recommendations on the intrinsic and extrinsic factors contributing to musculoskeletal injuries in professional ballet dancers. Aim: The aim of this study was to determine the incidence of musculoskeletal injuries and their associated risk factors over a three-month period in adult female professional ballet dancers in South Africa. Specific Objectives: The specific objectives of this study were: • To determine the incidence of traumatic and overuse injuries per 1000 dance hours over a three-month training and performance period in South African female professional ballet dancers; • To determine the relationships between a) Functional Lower Extremity Evaluation (FLEE) scores and injury incidence; b) intrinsic factors (amenorrhoea; body mass index; skinfold measurements; caloric intake) and injury incidence; and c) extrinsic factors (training hours; performance hours) and injury incidence respectively, in South African female professional ballet dancers. Methods: This study had a prospective, descriptive design. Eighteen female dancers were recruited from professional dance companies in the Gauteng, Western Cape and North West provinces of South Africa. Data were collected over a three-month period and included a subjective questionnaire, three-day food diary, skinfold measurements and the Functional Lower Extremity Evaluation (FLEE). Injuries were reported using an injury reporting form over the three-month period. Results: Participants had an average age of 22.1 ± 3.0 years. The dancers had an average BMI of 21.4 ± 2.1 kg.m⁻²; LBM of 41.7 ± 4.9 kg and body fat percentage of 24.7% ± 2.9%. Injury incidence was 3.3 injuries per 1000 dance hours with a total of 4605.58 hours reported overall. Of the 15 injuries reported, 13 occurred in the lower limb, with eight in the ankle and foot. Overuse injuries accounted for 93.3% of the total injuries, with only one traumatic injury reported. None of the descriptive characteristics was associated with increased injury risk. The average caloric intake of 1810.0 ± 503.7 calories, while lower than what is recommended for female athletes, also showed no significant relationship to injury. There were also no significant associations between pre-injury FLEE measurements and training loads; and injury incidence over the course of the study. Conclusion: An overall injury incidence of 3.3 injuries per 1000 dance hours was found in professional female ballet dancers in South Africa, which is higher than the injury incidences identified in previous studies in high-income countries. With regards to injury profile, overuse injuries are 86% more prevalent than traumatic injuries among this population type. We were unable to identify any intrinsic or extrinsic risk factors associated with injury incidence; however, we recognise the limitations of the small sample size in this study. With a high level of injury incidence and inconclusive results on injury risk factors, there is a clear need for significant further research in the field of injury prevention in professional ballet dancing. Further, this study identified a strong need for further research in South African dance companies to facilitate injury prevention and management in South Africa.

Pełny tekst źródłaStreszczenie:
Aircraft propellers in any flight condition other than pure axial flight are subject to an incident flowfield that gives rise to time-varying forces. Means of modelling these time-dependent forces have been presented in the literature, to varying degrees of success but a review of the different models is missing, and there is a need for an instructive means of simulation using physically realistic but computationally light methodologies. This dissertation provides a comprehensive overview of the relevant work to date, in addition to providing a logical framework in which the problem of propeller blade cyclic load variation may be assessed. Through this framework, the importance of different aerodynamic features pertinent to this problem are compared, and a new solution methodology based on adaptations of existing models is presented. This research project was commissioned by Dowty Propellers (DP), who chose Glasgow University and the supervisors for their rotorcraft simulation experience. Prediction of the propeller induced flowfield is shown to be of importance for the calculation of blade cyclic loads. Momentum models are fit for purpose owing to relative computational simplicity - this dissertation suggests a new radially-weighted implementation of momentum theory that provides better correlation with wind tunnel data than existing models. Swept propeller blades are discussed and the inherent problems faced by a designer or performance engineer are highlighted. An Euler transform to resolve velocities and forces between disc and blade element axes is presented, along with the assertion that ‘simple’ sweep correction methods can be deleterious to propeller aerodynamic simulation if used naïvely. Fundamentally, representation of a swept propeller blade by a blade element model is described as wholly more problematic than a straight propeller blade owing to the displacement of blade elements with respect to the blade pitch change axis - and that flow information will always be lost with such a representation. Installation effects are simulated and installed load fluctuations are predicted to a reasonable degree of accuracy compared to what little data is available. Different means of resolving installation velocities to disc and, subsequently, blade element axes are compared, and it is shown that representing installation effects by an effective incidence angle as is ‘standard practice’ will most likely underpredict installed load fluctuation. In addition to a varying blade root bending load caused directly by load fluctuation on a propeller at an angle of incidence, the reacted net loads at a propeller hub may include a constant yawing moment and in-plane force. This in-plane force has been well documented in the literature, but the equations for its calculation may miss a component of force due to a tilting of the blade tangential force. New equations for this additional force term are presented that validate well to legacy experimental data.

Cancer mortality has declined over the last three decades in most high-income countries reflecting improvements in cancer prevention, diagnosis, treatments, and management. However, there are persisting and substantial differences in mortality, incidence, and survival worldwide.
Using the World Health Organization (WHO) database I worked on the trends and projections analysis of mortality from various cancer sites. I computed age-specific rates for each 5-year age group, calendar year, and sex globally. I then computed age-standardized mortality rates per 100,000 person-years using the direct method based on the world standard population. I performed joinpoint models to identify the years when significant changes in trends occurred and I calculated the corresponding annual percent changes. For the mortality projections, I predicted the number deaths and rates for a specific calendar year, using a logarithmic Poisson count data joinpoint regression model.
My first study on this topic aimed to provide an up-to-date overview of trends in cancer mortality, incidence, and survival among adults, retrieving data from high-quality population-based cancer registries in seven high-income countries and the European Union. Mortality from all cancers and most common cancer sites has declined over the last three decades, except for pancreas and lung (in women). The patterns for incidence were less consistent between countries, except for a steady decrease in stomach cancer in both sexes and lung cancer in men. Survival for all cancers and the selected cancer sites increased in all countries, although there is still substantial variability. Although overall cancer death rates continue to decline, incidence rates have been levelling off among males and have been moderately increasing among females. These trends reflect population changes in cancer risk factors, screening test use, diagnostic practices, and treatment advances. Many cancers can be prevented or treated effectively if they are diagnosed early. Population-based cancer incidence and mortality data can be used to inform efforts to decrease the cancer burden and regularly monitor progress toward goals.
I had the opportunity to collaborate with the University of Miami Miller School of Medicine, which provided data on cancer mortality among Italy-born Americans in California, Florida, Massachusetts, and New York Departments of Vital Statistics. The comparison of cancer mortality rates and risk factors among foreign-born populations in a host country with those in the country of origin provides insights into differences in access to care, timely diagnosis, and disease management between the two countries. Moreover, cancer studies on specific European-born populations in the USA are scarce. Using official Italian death certificate data and resident population estimates based on the official census from the WHO, I was able to conduct a study to compare cancer mortality rates between Italians and Italy-born Americans. Generational differences in smoking prevalence patterns between the USA and Italy may explain the advantages for Italy-born Americans for lung and other tobacco-related cancers compared to their Italian male counterparts. The lower prevalence of Helicobacter pylori, alcohol consumption, and hepatitis B and C virus in the USA may justify the lower mortality for stomach and liver cancer, among Italy-born Americans. Earlier and more widespread adoption of cancer screening and effective treatments in the USA is likely to be influential in breast, colorectal, and prostate cancer mortality.
I then focused my studies on urologic cancer mortality over time and predictions. I carried out a time-trend analysis for selected European countries for prostate, testis, bladder, and kidney cancers over the last four decades. Prostate cancer mortality in the EU decreased over recent years and the projections are favorable. Less favourable trends were observed in eastern Europe, though starting from relatively low rates. Testicular cancer mortality declined over time in most countries, however levelling off in northern and western countries, after reaching very low rates. Bladder cancer mortality trends were less favourable in central and eastern countries compared to northern and western ones. Kidney cancer mortality reported a slight increase in men and stable rates in women over the last decade in the EU. To sum up, over the last four decades, mortality from prostate, testis, and bladder cancers but not from kidney cancer, declined in most European countries. Prostate cancer mortality rates remain lower in Mediterranean countries than in northern and central Europe. Rates for all urologic cancers remain higher in central and eastern Europe. I wrote a book chapter on the epidemiology of prostate cancer, including all the aspects I studied for my PhD.
In addition, I published as a co-author other papers on mortality over time and prediction analysis focusing on different aspects and various cancer mortality causes: mortality from soft tissue sarcomas, childhood cancer mortality, colorectal cancer mortality in young adults, and mortality from gastric and esophageal cancer, and differences between eastern and western EU cancer mortality. I submitted an abstract for the Africa Mortality Symposium on mortality cancer trends in the Republic of South Africa, the Republic of Mauritius, and Réunion and I am currently working on European prediction of cancer mortality rates for 2023. The research group I work has been publishing cancer mortality predictions annually since 2011.
Moreover, during these three years, I was involved in the CEFIC project (PI Prof. Negri from University of Bologna) titled “Incidence trends of selected endocrine-related diseases and conditions in Europe and North America, and the contribution of changes in human reproduction”. Among the endocrine-related diseases and conditions, there were four cancer sites considered: endometrium, breast, testis, and prostate. I gave my contribution to this project by evaluating the cancer incidence trends in high-income countries worldwide and reviewing the association between selected reproductive factors and the selected cancers. Thus, we investigated changes in relevant reproductive factors and estimated their influence on cancer occurrence.
During my PhD, I have been collaborating with the department of Oncology at the Mario Negri Institute. Under the supervision of Dr Bosetti I have worked on various projects. In particular, I was involved in updating of a meta-analysis concerning aspirin use and the risk of twelve solid tumors with a dose-response analysis finalizing three publications. Moreover, the Mario Negri Institute manages the Italian Register of Multiple Sclerosis, collecting data from more than 100 Italian centers including more than 70.000 patients. Based on this real-world dataset, I have dealt with several aspects related to multiple sclerosis, being involved in the drafting of two papers one concerning two methods for measuring the disability accumulated over time and another one studying patients’ and referral centers’ characteristics in relation to multiple sclerosis phenotypes.
In my last PhD year, I worked at the Department of Quantitative Methods and Economics of the University of Las Palmas supervised by Prof. Serra-Majem for nine months. This training period aimed to gain new experience in conducting cost-effectiveness studies. I conducted a study aimed to quantify the over cost due to obesity among patients hospitalized for Covid-19. In collaboration with the Department of Public Health, I conducted an effectiveness analysis of a primary prevention intervention with a Mediterranean diet supplemented with extra-virgin olive oil or nuts using the data from PREDIMED Trial. Lastly, I took part in the WOMEDS Study, a project aimed to analyse gender inequality among medical doctors in Spain. During these months abroad, I co-wrote three papers, currently under revision.

Introduction: The Mortality–Incidence Ratio complement [1 – MIR] is an indicator validated in various populations to estimate five-year cancer survival, but its validity remains unreported in Peru. This study aims to determine if the MIR correlates directly with five-year survival in patients diagnosed with the ten most common types of cancer in metropolitan Lima. Materials and methods: The Metropolitan Lima Cancer Registry (RCLM in Spanish) for 2004–2005 was used to determine the number of new cases and the number of deaths of the following cancers: breast, stomach, prostate, thyroid, lung, colon, cervical, and liver cancers, as well as non-Hodgkin’s lymphoma and leukaemia. To determine the five-year survival, the five-year vital status of cases recorded was verified in the National Registry of Identification and Civil Status (RENIEC in Spanish). A linear regression model was used to assess the correlation between [1 – MIR] and total observed five-year survival for the selected cancers. Results: Observed and estimated five-year survival determined by [1 – MIR] for each neoplasia were thyroid (66.7%, 86.7%), breast (69.6%; 68%), prostate (64.3%, 63.8%) and cervical (50.1%, 58.5%), respectively. Pearson’s r coefficient for the correlation between [MIR – 1] and observed survival was = 0.9839. Using the coefficient of determination, it was found that [1 – MIR] (X) captures the 96.82% of observed survival (Y). Conclusion: The Mortality–Incidence Ratio complement [1 – MIR] is an appropriate tool for approximating observed five-year survival for the ten types of cancers studied. This study demonstrates the validity of this model for predicting five-year survival in cancer patients in metropolitan Lima.

A point-weighted structure is an incidence structure with each point assigned an element of some set W C Z+ as a 'weight'. A point-weighted structure with no repeated blocks and the property that the sum of the weights of the points incident with anyone block is a constant k is called a point-weighted design. A t - (v, k, Aj W) point-weighted design is such a structure with the sum of the weights of all the points equal to v and the property that every set of t distinct points is incident with exactly A blocks. This thesis introduces and examines this generalisation of block designs. The first chapter introduces incidence structures and designs. Chapter 2 introduces and defines point-weighted designs. Three constructions of families of t - (v, k, Aj W) point-weighted designs are given. Associated with any point-weighted design is the incidence structure on which it is based - the 'underlying' incidence structure (u.i.s.). It is shown in Chapter 3 that any automorphism of the u.i.s. of a t - (v, k, Aj W) point-weighted design with more than one block and t > 1 preserves weights in the point-weighted design. The u.i.s. of such a point-weighted design is shown to be a block design if and only if every point is assigned the same weight. A necessary and sufficient condition is obtained for the assignment of weights in any point-weighted design to be essentially uniquely determined by the u.i.s. Chapter 4 considers t-{v, k, Aj W) point-weighted designs in which all of the points apart from a 'special' point have the same weight. It is shown that when v > k the weight of the special point is an integer multiple of the weight assigned to all the other points. A class of these point-weighted designs is demonstrated to be equivalent to a class of group-divisible designs with specific parameters. The final chapter uses the procedure of point-complementing incidence structures to construct point-weighted designs. Trivial point-weighted designs are defined and a necessary and sufficient condition for the existence of a member of a certain class of these is obtained. A correspondence between this class of point-weighted designs and certain trivial block designs is given using point-complementing.

The definition of awareness used consistently in this thesis is: Explicit recall of intraoperative events during general anaesthesia. Since there is no objective method to detect awareness, the patients must be interviewed after anaesthesia. The form and timing of the interview is crucial. To rely on spontaneous disclosure of awareness episodes is not sufficient. The total number of awareness-victims is considerable although the incidence may seem modest. A number of these patients look upon the awareness experience as the worst experience in their life. Suffering can include pain, mental distress and delayed psychological symptoms. However, the experience of awareness is not uniform and not all patients suffer. A comprehensible definition for dreaming during anaesthesia is: Any recalled experience, excluding awareness, which occurred between induction of anaesthesia and the first moment of consciousness upon emergence. Some findings point in the direction that dreaming during anaesthesia may be related to light or insufficient anaesthesia, but other findings do not. Some patients find dreaming during anaesthesia distressing, but generally the overall impression is that consequences of dreaming during anaesthesia seem to be small and of minor importance to the majority of patients. In this thesis I have found the following:The incidence of awareness is approximately 0.2% when neuromuscular blocking drugs are used and awareness also exists without these drugs, albeit to a lesser extent. These findings represent standard practice in an adult population at normal risk. 50% of awareness cases may have delayed recall of awareness. Using a consecutive inclusion design we found initial awareness suffering comparable to previous studies, but a lower incidence and less pronounced severity of late psychological symptoms. The incidences found among the awareness-victims in our study were; experience of pain 46%, immediate mental distress 65%, any late psychological symptom 33%, and PTSD below 10%. A memory of an intraoperative dream after general anaesthesia is not an early interpretation of delayed awareness, indicating that no routine follow up of dreaming-only patients is indicated. Dreams reported after anesthesia are generally not related to insufficient anesthesia defined as high BIS, and should not be regarded as near awareness.

Lichen sclerosus (LS) is a well-recognised inflammatory dermatosis but the aetiology remains uncertain. It has a predilection for the anogenital area and affects both sexes at all ages. In females it presents most commonly post menopausally but also affects a considerable number of prepubertal children. In this thesis I wished to document how commonly lichen sclerosus affects children, what the possible causes may be, to find the ideal treatment to minimise both short and longterm problems and lastly to clarify whether the longterm risks for this group ofchildren after puberty are the same as those for adults. Development of the specialist dermatology paediatric vulval clinic proved the ideal setting for studying the presentation, clinical features and course of the disease in girls and the paediatric urology clinic offers the same facility for boys. Both genetic and environmental factors may play a role in the aetiology of lichen sclerosus and assessment of familial incidence, immunogenetics and possible infective 'triggers' provide further areas of study. Lastly, treatment options have been assessed, the course of the disease recorded and risks for the future including development of malignancy is addressed. I The incidence of childhood lichen sclerosus is assessed using sources below 1. paediatric dermatology clinic presentation 2. paediatric urology clinic presentation 3. numbers diagnosed histologically per year 4. numbers from the GP database II Epidemiological data - 3 Supplied by The British Library - 'The world's knowledge' collected from patients by means ofquestionnaires and facts gathered during the course of diagnosis, treatment and follow up in clinic. This documents the increasing incidence oflichen sclerosus in children and its possible relation to anxieties about sexual abuse. III Genetic Influences Familial incidence oflichen sclerosus and its association with autoimmunity is confirmed. HLA tissue typing in the department ofTransplant Immunology at The Churchill, Oxford allowed examination ofimmunogenetic influences. The association with HLA class II DQ7 is documented in prepubertal girls with LS. IV Environmental Influences Several infective triggers have been suggested for the onset oflichen sclerosus, investigated and refuted. Considering the role ofhuman papilloma virus (HPV) as a trigger for lichen sclerosus we investigated cohorts ofmale and female children with LS for the presence ofHPV compared to controls. HPV DNA was detected and typed using a nested PCR technique with the help ofthe Microbiology and PHL at Addenbrookes Hospital Cambridge. HPV carriage is common in all children but girls with LS were found to carry more dysplastic-associated types ofHPV. The incidence ofabnormal smears and anogenital warts in mothers ofaffected children is also raised. Sexual abuse has also been suggested as a possible trigger for the onset oflichen sclerosus but the figures in this study do not support this. V Clinical Data Information is gathered from paediatric vulval and urology clinics as to mode and age ofpresentation ofLS. The natural history ofthe disease and how it is influenced by treatment is studied retrospectively and prospectively, and ideal treatment regimes formulated. Studying postpubertal children with LS suggests that the disease does not always clear at puberty so there is a theoretical risk of suffering the disease in adulthood with the concomitant risk ofdeveloping associated malignancy. It is wise to give patients and parents the information given to adults with the disease in case of problems later in life even if the children appear to be 'disease-free' after treatment.

Introduction:
Cancer differentially affects populations and geographical regions. Given the ethnic diversity and growing population of immigrants in Canada and British Columbia in particular, it is important to understand how the risk of cancer is distributed according to where in BC immigrants live, given that this population may experience distinct cancer risks.
Objectives:
The purpose of this study is to understand how cancer incidence rates in BC vary by the regional proportion of immigrants and to explore how these rates are associated with duration of residence (recent versus well established), age at immigration, and country of origin.
Methods:
Analyses were conducted using a dataset of adult incident cancers diagnosed in BC (2000 to 2009) collected by the BC Cancer Registry. Regional-level estimates of the proportion of immigrants, as well as the socioeconomic and ethnic profiles of the BC population, were obtained from the Statistics Canada 2006 Census (defined by Local Health Area) and linked to the Cancer Registry data. Poisson and Negative Binomial regression models were used to estimate the rate ratios (RR) of cancer incidence by proportion of immigrants.
Results:
Overall, regional immigrant density significantly predicted lower cancer incidence rates for all-cancers and the most common cancers of the breast, prostate, colon and lung. However, for less common cancers of the liver, stomach and pharynx, proportion of immigrants significantly predicted higher cancer risk. This association was seen for recent and established immigrants, although cancer rates were higher among established immigrants. The proportion of immigrants at a younger age at immigration and from European origin were associated with increased risk for all-cancers and common cancers, but decreased risk of less common cancers. The proportion of immigrants at an older age at arrival (particularly 45 years and older) and from Asian origin were associated with decreased all-cancer risk and the risk of common cancers, but increased risk of less common cancers.
Conclusion:
Regional-level concentration of immigrants predicted cancer incidence rates in BC. Regional data on cancer incidence is important for developing effective health promotion strategies and public health planning by various Local Health Areas and health authorities in BC.Medicine, Faculty of
