Abstract:
Swine veterinarians in North America have applied oral fluid-based testing methodologies for an increasing number of systemic, respiratory, and enteric disease diagnostic applications. Since the first report of oral fluid testing in 2008, nucleic acid and antibody assays have been described in the peer-reviewed literature for many pathogens affecting swine. As evidence of the US swine industry’s growing utility of oral fluids as a diagnostic tool, the cumulative number of swine oral fluid diagnostic tests conducted at three veterinary diagnostic laboratories in the upper Midwest (Iowa State University, South Dakota State University, and University of Minnesota) has increased from approximately 21,000 tests in 2010 to nearly 370,000 tests in 2016. The objective of this review is to describe the developments in oral fluid diagnostics that have led to its widespread use and to highlight areas of concern as this technology is increasingly implemented by producers and veterinarians.

Abstract:
Diagnostic reference levels (DRLs) are a pivotal strategy to be implemented since pediatric interventional cardiology procedures are increasing. This work aimed to propose an initial set of Brazilian DRLs for pediatric interventional diagnostic and therapeutic (D&T) procedures. A retrospective study was carried out in four Brazilian states, distributed across the three regions of the country. Data were collected from pediatric patients undergoing cardiac interventional procedures (CIPs), including their age and anthropometric characteristics, and at least four parameters (number of images, exposure time, air kerma–area product—PKA, and cumulative air kerma). Data from 279 patients undergoing CIPs were gathered (147 diagnostic and 132 therapeutic procedures). There were no significant differences in exposure time and the number of images between the D&T procedures. A wide range of PKA was observed when the therapeutic procedures were compared to diagnostics for all age groups. There were significant differences between the D&T procedures, whether grouping data by patient weight or age. In terms of cumulative air kerma, it was noted that no value exceeded the level to trigger a monitoring process for patients. This study shows that it is possible to adopt them as the first proposal to establish national DRLs considering pediatric patient groups.

Abstract:
SummaryBackground: Patient-reported outcomes (PROs) are essential components of wound and vascular diagnostics and management. Aim: To provide an overview of PROs as diagnostic tools in the management of chronic wounds.Methods: Review of different concepts on inclusion of PROs in wound practice from literature.Results: PROs are indispensable sources of information for the understanding of the biopsycho- social context of wound diseases. Essential dimensions to be recorded are pain, health-related quality of life and patient benefit. Psychological parameters, adherence, treatment goals and treatment benefits are often needed. Further fields of interest include cumulative life course impairment, coping with disease, stigmatisation specifically applied according to clinical questions.Conclusion: Patient-reported outcomes are mandatory for the diagnostic work-up of chronic wounds. They also provide essential information in the course of a disease, can be diagnostic clues for non-adherence and treatment failures. Measurement of many PRO parameters in wound disease, such as health-related quality of life and pain, is facilitated by validated instruments, which are recommended for practice.

Abstract:
The research is devoted to steel structure diagnostics by the acoustic emission (AE) method. The existing regulatory documents for AE diagnostics of metals and alloys do not take into account some critical factors, among which one is the scale factor should be highlighted. As a result, this can lead to an unreliable assessment of the danger degree of defects in structures when using standard AE diagnostic criteria. This paper presents a quantitative assessment of the scale factor impact on the AE data during the static tension test of steel specimens to failure. Experimental studies were carried out on flat specimens of various thicknesses with a side notch made of high-quality alloyed steel 30 KhGSA. It was established that AE data changed (rise in the AE signals amplitudes and AE activity) within the increase of specimen thickness. Growth in the recorded AE signals cumulative energy was registered with a greater specimen thickness. Partial correlation dependences of the mean count frequency and cumulative energy of AE signals on the specimen thickness were obtained. It was shown that such an effect occurred due to both a general increase in the deformed metal volume and greater strain intensity during the tension of thick specimens. The obtained dependences may contribute to the development of AE diagnostics of metallic materials which is invariant to the scale factor impact.

Abstract:
Le diagnostic cumulatif des systèmes dynamiques nécessite la détection, l’identification et la caractérisation des dégradations naissantes. Son application à l'usinage à grande vitesse, par exemple, pourrait s’appuyer sur l’analyse des phénomènes de bifurcations de période-N pour détecter et identifier les chatters (broutages) naissants et améliorer la qualité des produits et des processus de fraisage. Jusqu'à présent, de nombrecuses méthodes efficaces ont été proposées pour détecter les broutages naissants et identifier les bifurcations de période-N. Cependant, ces méthodes peinent à mettre en œuvre ces tâches de manière fiable et précise. Le but de la présente thèse est de développer et mettre en œuvre des méthodes de détection de broutages naissants et d’identification de bifurcations de période-N dans une approche de diagnostic cumulatif temps réel. Afin de détecter les défauts de broutages naissants (early-chatter), nous avons proposé trois méthodes de détection et une méthode d’identification pour le diagnostic cumulatif. La première méthode peut être utilisée pour détecter à distance les broutages naissants. La deuxième méthode détecte rapidement les broutages naissants dans des conditions spécifiques de fonctionnement et de mesure. Mais dans la pratique, les conditions de fonctionnement et de mesure sont complexes et variables. Pour s'adapter aux différentes conditions de fonctionnement et de mesure, nous avons proposé une troisième méthode et cette dernière détecte de manière fiable les broutages naissants. On note également que dans les processus de fraisage, les broutages peuvent naître avec une bifurcation de type période-N ou de type Hopf. La qualité d'usinage sous un processus de bifurcation de type période-N est moins critique que celle de type Hopf. Ainsi, il est indispensable d’identifier précocement les bifurcations de type période-N pour améliorer l'efficacité d'usinage. Pour cela, nous avons développé une méthode d’identification du type et de la taille des bifurcations de période-N. Nous avons également prouvé l'efficacité des méthodes proposées, en utilisant deux modèles de processus de fraisage de référence. De plus, les méthodes proposées peuvent être utilisées pour le diagnostic de défaut d'autres systèmes dynamiques, tels que les systèmes de conversion d'énergie par modulation de largeur d'impulsion ou systèmes de paliers ou d’engrenageCumulative diagnosis of dynamic systems requires the detection, identification, and characterization of incipient degradations. Its application to high-speed machining, for instance, could rely on period-N bifurcations phenomena analysis to detect and identify early-chatters and improve the quality of milling products and processes. Up to now, many efficient methods were proposed to detect early-chatter and identify period-N bifurcations. But these methods are struggling to implement these tasks reliably and accurately due to the complex nonlinear characteristics of their dynamic behaviors, the noise, and the variation of their operating conditions. The present thesis aims to develop and implement methods of early-chatter detection and period-N bifurcations identification within a real-time cumulative diagnosis approach. Aimed at early-chatter detection, we proposed three detection methods and one identification method for the cumulative diagnosis. The first method can be used to detect early-chatters remotely. The second one detects early-chatter quickly under specific operating and measuring conditions. However, in practice, the operating and measuring conditions are complex and variable. To adapt to different operating and measuring conditions, we proposed a third method, and the latter detects early-chatter reliably. It is also noted that in milling processes, the early-chatter can give rise to a bifurcation of period-N or Hopf type. The machining quality under the bifurcation process of the period-N type is less critical than that under the Hopf bifurcation type. To improve machining productivity and ensure the required machining quality, we can mill the workpiece under the condition of period-N bifurcations. Thus, it is compulsory to identify the early period-N bifurcations for improving machining productivity. For that purpose, we developed a method for identifying the type and size of the period-N bifurcations. We also proved the effectiveness of the proposed methods, using two benchmark milling process models. Besides, the proposed methods can be used for fault diagnosis of other dynamic systems, such as the pulse energy conversion systems or bearing or gearing systems

Abstract:
Introdução: As atividades com grupos complementando os procedimentos terapêuticos são freqüentemente utilizadas na área de saúde do trabalhador, especialmente para os pacientes com LER/DORT. Este estudo tem por objetivo avaliar os possíveis benefícios da associação do tratamento cinesioterapêutico convencional com dinâmicas de grupo e verificar se o tratamento fisioterapêutico em grupo potencializa os efeitos da cinesioterapia em pacientes com LER/DORT. Método: Participaram do estudo 24 pacientes com diagnóstico de LER/DORT que foram distribuídos aleatoriamente para os dois tipos de intervenção: individual e em grupo. O protocolo de cinesioterapia foi o mesmo para as duas intervenções e teve duração de dez sessões. Os pacientes submetidos à intervenção em grupo participaram de dinâmicas grupais com temáticas previamente estabelecidas para instigar a discussão de aspectos considerados importantes durante o tratamento. A análise das intervenções foi feita por meio da avaliação do quadro doloroso (EVA, Questionário de Dor de McGill e Questionário Nórdico de Sintomas Osteomusculares), da avaliação da funcionalidade (Questionário DASH) e da avaliação da amplitude de movimento das articulações dos membros superiores. Além disso, foi realizada uma entrevista semi-estruturada para avaliar qualitativamente o impacto dessas intervenções no quadro clínico e na qualidade de vida destes pacientes. Resultados: Na avaliação quantitativa do quadro doloroso foi observado que a intervenção em grupo não produziu efeitos para o controle da dor, especialmente para diminuição da intensidade álgica. A análise do questionário DASH revelou que o tratamento individual e o em grupo não produziram efeitos na funcionalidade das atividades de vida diária e do trabalho. O aumento da amplitude de movimento em todas as articulações de membros superiores em ambas as intervenções não foi considerado significativo. Entretanto, a análise qualitativa apontou que os pacientes que participaram da intervenção em grupo relataram uma percepção de melhora do quadro doloroso e da funcionalidade em suas vidas; houve uma reflexão gerada a partir das dinâmicas de grupo trazendo uma nova percepção de saúde e do adoecimento Conclusão: A intervenção em grupo não potencializou os efeitos da cinesioterapia no controle do quadro doloroso, na melhora da funcionalidade e no aumento das amplitudes de movimento das articulações de membros superiores, mas o tratamento cinesioterapêutico convencional associado a dinâmicas de grupo permitiu uma abordagem mais global do processo de adoecimento, recuperação e reabilitação do paciente com LER/DORT e modificou as estratégias de enfrentamento dos processos dolorosos e dos conflitos cotidianos desses indivíduosIntroduction: The group activities are often used to complement therapeutic procedures in the laborers health area, especially for RSI/WMSD patients. This studys aim is to evaluate the possible benefits of associating the conventional kinesiotherapeutic treatment with group dynamics and check if the group physical therapeutic treatment potentializes the effects of kinesiotherapy in RSI/WMSD patients. Method: Twenty four RSI/WMSD patients took part in the study. They were randomly distributed for both kinds of interventions: the individual and the group treatments. The kinesiotherapy protocol was the same for both interventions and it lasted ten sessions. The patients submitted to group intervention took part in group dynamics with previously established themes to instigate the debate on aspects considered important during treatment. The interventions analysis was performed by the evaluation of pain conditions (VAS, McGill Pain Questionnaire, NMQ), of functionality (DASH Questionnaire), and of the upper limb joint movements. Furthermore, a semi-structured interview was performed to qualitatively evaluate the impact of these interventions in these patients clinical condition and quality of life. Results: In the quantitative evaluation of the pain condition it was evidenced that the group intervention was not effective for pain control, especially in the decrease in the intensity of pain. The DASH questionnaires analysis revealed that the individual and the group treatments were not effective in the functionality of daily life and labor activities. The increase in the movement amplitude in every upper limb joint in both interventions was not considered significant. Nonetheless, the qualitative analysis pointed out that those patients who took part in the group intervention reported the perception of improvement in the pain condition and in functionality in their lives; a reflection born within the group dynamics brought a new perception on health and illness. Conclusion: The group intervention did not potentialize the effects of kinesiotherapy in controlling pain, in improving functionality, and in increasing movement amplitudes in the upper limb joints, but the conventional kinesiotherapeutic treatment associated to group dynamics allowed a more global approach of the RSI/WMSD patients illness, recovering, and rehabilitation process and modified the strategies for dealing with these individuals pain processes and daily conflicts

Abstract:
Introduction: This study described patterns of imaging and cumulative effective dose (CED) from diagnostic radiation in young adult survivors (YAS) of malignancies and cancer-free controls in Ontario.
Methods: Persons aged 20-44 diagnosed with malignancy between 1992 and 1999 who lived at least 5 years without recurrent disease were matched to controls without a prior cancer diagnosis. The rate at which YAS received diagnostic studies and associated CED was compared to controls using multivariable regression techniques.
Results: 20,911 YAS and 104,524 controls were included. YAS received CT scanning at a significantly higher rate than controls (rate ratio = 3.49, 95% confidence interval [CI]: 3.37 – 3.62. YAS received a 4.57-fold higher CED than controls (95% CI: 4.20 – 4.57).
Conclusions: YAS are exposed to diagnostic radiation at significantly higher rates than controls even after 5 years of recurrence-free survival. Alternative imaging techniques not associated with radiation should be considered for these patients.

Abstract:
Necrotizing fasciitis (NF) is a rare and life threating soft-tissue infection specific to the skin’s fascia layer. It is most often encountered in the peripheries, abdominal wall, and perineum and has numerous etiologies and associated pathogens. Early diagnosis and rapid surgical debridement are essential in treating NF as the infection progresses rapidly and mortality rate increases significantly with time. The current difficulty in initial diagnosis is due to the lack of obvious skin findings early on in the infection. Laboratory tests, including the laboratory risk indicator for necrotizing fasciitis (LRINEC) score, gas on imaging tests, and physical exam findings are the current clues to an early diagnosis but official diagnosis can only be confirmed by surgical exploration and discovery of a lack of resistance to dissection in the fascia layer. The LRINEC score analyzes one variable, specifically C-reactive protein (CRP), which is often not included in routine laboratory tests skin infections at the emergency department (ED). Furthermore, no specific set of physical exam findings has been distinctly associated with diagnosis of NF over other soft-tissue infections and the most specific imaging tests are too expensive for routine use. A new and modified LRINEC score based only on routine ED laboratory tests as well as an additional objective scoring system for physical exam findings are the next steps toward rapid diagnosis. This approach requires large-scale retrospective statistical analyses of NF cases across the country for identification of the most prevalent physical exam findings and abnormal laboratory values.

Abstract:
Trabalho de projeto de mestrado em Bioestatística, Universidade de Lisboa, Faculdade de Ciências, 2021O cancro do pulmão é dos cancros mais fatais a nível mundial. As estimativas em 2018 para Portugal indicam que 4671 indivíduos morreram de cancro do pulmão, o que corresponde a 16.1% do total de mortes causadas por cancro. Estima-se que existam 5284 novos casos por ano, correspondendo a 9.1% de todos os cancros. A taxa de incidência para homens é 38.8 por cada 100000 habitantes enquanto que para mulheres é 12.6 por cada 100000 habitantes, o que corresponde a um aumento de 75%. A elevada taxa de mortalidade neste tipo de cancro pode ser justificada pelo facto de se tratar de uma doença assintomática. Cancros em estadios avançados têm um prognóstico pouco favorável quando comparados com cancros detetados em estadios menos avançados, daí a importância de um diagnóstico precoce. O estadio determina a escolha de tratamento e representa a severidade do tumor, o que influenciará o tempo de sobrevivênia. A classificação TNM é um sistema de estadios criado com base em três critérios de informação: o tamanho do tumor primário (T), extensão para os nódulos linfáticos vizinhos (N) e extensão para orgãos distantes (M). De acordo com os exames de diagnóstico, a doença pode ser classificada como I, II, IIIA, IIIB or IV, sendo um indicador da severidade da doença. A nova campanha , Treatment for All, da União para o Controlo Internacional do Cancro tem como objetivo reduzir a morte prematura de cancro e promove o acesso equitativo para o tratamento e bem-estar. As condições socioeconómicas são alguns dos fatores que podem comprometer o acesso aos cuidados de saúde. Portanto, o principal objetivo deste estudo foi perceber se os fatores socioeconómicos e o acesso aos cuidados de saúde estão associados com o estadio em que o cancro é diagnosticado. A informação foi recolhida pelo Registo Oncológico Regional Sul (ROR-Sul), que inclui as regiões de Lisboa e Vale do Tejo, Alentejo, Algarve e Região Autónoma da Madeira. O conjunto de dados tinha incluído 2266 pacientes diagnosticados com cancro do pulmão em 2013 e 2014. As variáveis incluídas foram o género, idade, concelho de residência, distrito de residência, morfologia, lateralidade, estadio ao diagnóstico e estado vital. As variáveis socioeconómicas foram extraídas a partir do INE e PORDATA. Através da revisão de literatura, foram identificados alguns indicadores que caraterizam as condições socioeconómicas, bem como as de acesso aos cuidados de saúde. Os dados foram modelados aplicando o modelo de regressão ordinal e o modelo misto de regressão ordinal, usando o concelho de residência como um efeito aleatório, que corresponde à variável que liga o conjunto de dados originais aos indicadores socioeconómicos e de acesso aos cuidados de saúde. O termo aleatório explicará as diferenças entre os concelhos e reduz a componente por explicar do modelo sem um termo aleatório. A correlação linear foi analisada para evitar a inclusão de variáveis independentes fortemente correlacionadas. A variável escolhida entre o par fortemente correlacionado era a mais informativa, excluindo aquela que, sendo menos informativa, estava associada à que foi incluída. A influência de cada uma das variáveis foi analisado de acordo com o odds ratio (OR). Considerando o sinal dos coeficientes de regressão, os resultados do modelo múltiplo sem termo aleatório indicaram que maior número de médicos por cada 1000 habitantes (OR 0.974, 95% CI: 0.942 - 1.008), idades avançadas (OR 0.996, 95% CI: 0.989 - 1.004) e maior número de beneficiários por cada 1000 habitantes (OR 0.998, 95% CI: 0.993 - 1.004) aparentam favorecer estadios mais baixos. Um maior rendimento anual (OR 1.003, 95% CI: 0.949 - 1.060) e um maior número de atendimentos por cada 1000 habitantes (OR 1.005, 95% CI: 0.995 - 1.016), aparentam contribuir para um diagnóstico em estadios avançados. O impacto do género variou de acordo com a categoria da variável resposta. Incluindo o termo aleatório, os resultados também indicaram que um elevado número de médicos por cada 1000 habitantes (OR 0.971, 95% CI: 0.880 - 1.073), uma idade avançada (OR 0.996, 95% CI: 0.988- 1.004) e um maior número de beneficiários por cada 1000 habitantes (OR 0.998, 95% CI: 0.988 - 1.009) aparentam favorecer estadios menos avançados. Um elevado rendimento anual (OR 1.008, 95% CI: 0.942 - 1.078) e um maior número de atendimentos por cada 1000 habitantes (OR 1.007, 95% CI: 0.988 - 1.026) aparentam contribuir para um diagnóstico em estadios avançados. Ao contrário do modelo sem termo aleatório, o efeito do género não varia de acordo com a severidade da doença. Com base no sinal do seu coeficiente de regressão, a possibilidade de um homem ser diagnosticado num estadio avançado era menor que uma mulher (OR 0.866 , 95% CI: 0.572 - 1.312). Apesar da variância associada ao termo aleatório (concelho de residência) tenha sido próxima de 1, a diferença entre estas regiões foram estatisticamente significativas no que diz respeito à severidade do estadio ao diagnóstico. A análise geoespacial mostrou que uma região do Centro tinha menor possibilidade de diagnóstico em estadios superiores. Na Região Autónoma da Madeira, a possibilidade de diagnóstico em estadios superiores era maior. Os resultados dos modelos múltiplos não encontraram evidências de associação entre as condições socioeconómicas e o acesso aos cuidados de saúde e a severidade do cancro do pulmão. O trabalho futuro deve passar pela recolha de mais informações individuais sobre o paciente, como estado civil, hábitos tabágicos, alimentção, mas também condições económicas e de acesso aos cuidados de saúde, como ter médico de família, proximidade de centros de saúde, facilidade para sair do trabalho, cobertura de seguro, etc.
Lung cancer is the most lethal type of cancer worldwide. The estimates for Portugal in 2018 indicate that 4671 individuals died of lung cancer, corresponding to 16.1% of total cancer deaths, with 5284 new cases estimated per year, corresponding to 9.1% of all cancers. The incidence rate for males is 38.8 per 100000 inhabitants whereas for females is 12.6 per 100000 inhabitants, which corresponds to an 75% increase. The high mortality rate of this type of cancer can be attributed to the fact that it is an asymptomatic disease, which delays diagnosis. Cancers in more advanced stages have reduced favourable prognosis compared to cancers detected in earlier stages, hence the importance of early diagnosis. The stage determines the choice of treatment and represents the severity of the tumour, which will influence survival time. TNM classification is a staging system created based on three information criteria: the size of the primary tumor (T), the spread to nearby lymph nodes (N) and the spread to distant organs (M). According to the diagnostic exams, the disease can be classified as I, II, IIIA, IIIB or IV, being an indicator of the severity of the disease. The new campaign, Treatment for All, of the Union for International Cancer Control (UICC) aims to reduce premature mortality from cancer and promote equitable access to treatment and care. Socioeconomic conditions can compromise access to primary health care. Therefore, the main aim of this study was to understand if socioeconomic factors and access to primary health care are associated with the stage at which the cancer is diagnosed. Data were collected from the Southern Portugal Cancer Registry (ROR-Sul), which includes the regions of Lisbon and the Tagus Valley, Alentejo, Algarve and Autonomous Region of Madeira. The dataset had included 2266 patients diagnosed with lung cancer in 2013 and 2014. The variables included in the original dataset were gender, age, residence county, residence district, morphology, laterality, stage at diagnosis and vital status. Socioeconomic variables were downloaded from the INE and PORDATA. Through a literature review several indicators characterizing the socioeconomic conditions as well as the access to healthcare conditions were identified. The data were modelled applying the ordinal regression model and the ordinal regression mixed model using the residence county as a random effect, which corresponds to the variable that links the original dataset to the socioeconomic and access healthcare indicators. The random term will explain the differences between counties and reduce the unexplained component of the model without a random term. The linear correlation was analysed to avoid the inclusion of strongly correlated independent variables. The variable chosen among the strongly correlated pair was the most informative, excluding the one that, being less informative, was associated with the one that was included. The influence of each variable was analysed according to the odds ratio (OR). Considering the sign of the regression coefficients, the results of the multivariable model without random term indicated that higher number of doctors per 1000 inhabitants (OR 0.974, 95% CI: 0.942 - 1.008), higher age (OR 0.996, 95% CI: 0.989 - 1.004) and higher number of welfare recipients per 1000 inhabitants (OR 0.998, 95% CI: 0.993 - 1.004) appeared as favouring lower stages. A higher annual income (OR 1.003, 95% CI: 0.949 - 1.060) and a higher number of attendances per 1000 inhabitants (OR 1.005, 95% CI: 0.995 - 1.016), appeared as contributing to a diagnosis in higher stages. The impact of gender varied according to the category. Including the random term, the results also indicated that a higher number of doctors per 1000 inhabitants (OR 0.971, 95% CI: 0.880 - 1.073), a higher age (OR 0.996, 95% CI: 0.988 - 1.004) and a higher number of welfare recipients per 1000 inhabitants (OR 0.998, 95% CI: 0.988 - 1.009) appeared favouring lower stages. A higher annual income (OR 1.008, 95% CI: 0.942 - 1.078) and a higher number of attendances per 1000 inhabitants (OR 1.007, 95% CI: 0.988 - 1.026), appeared as contributing to a diagnosis in higher stages. Unlike the model with no random term, the effect of gender does not vary according to the severity of the disease. Based on the sign of its regression coefficient, the odds of a male being diagnosed at a later stage was less than a woman (OR 0.866, 95% CI: 0.572 - 1.312). Although the variance associated with the random effect (residence county) was close to 1, the difference within regions were statistically significant regarding the severity of stage at diagnosis. The geospatial analysis has shown that a region in the Center had a lower possibility of having a diagnosis at higher stages. In the Autonomous Region of Madeira, the possibility of having a diagnosis at higher stages was higher. The multivariable models results found no evidence of a statistically significant association between socioeconomic conditions and access to healthcare, as they were measured, and lung cancer severity. Future work should collect more individual information about the patient, such as marital status, smoking habits, diet, but also economic conditions and conditions accessing healthcare, such as having a family doctor, proximity to health centres, ease of leaving work, insurance coverage, etc.

has been widely used in the statistical literature. In this thesis, we investigate the
merits of empirical likelihood for various problems arising in ratio estimation. First,
motivated by the smooth empirical likelihood (SEL) approach proposed by Zhou &
Jing (2003), we develop empirical likelihood estimators for diagnostic test likelihood
ratios (DLRs), and derive the asymptotic distributions for suitable likelihood ratio
statistics under certain regularity conditions. To skirt the bandwidth selection problem
that arises in smooth estimation, we propose an empirical likelihood estimator
for the same DLRs that is based on non-smooth estimating equations (NEL). Via
simulation studies, we compare the statistical properties of these empirical likelihood
estimators (SEL, NEL) to certain natural competitors, and identify situations
in which SEL and NEL provide superior estimation capabilities.
Next, we focus on deriving an empirical likelihood estimator of a baseline cumulative
hazard ratio with respect to covariate adjustments under two nonproportional
hazard model assumptions. Under typical regularity conditions, we show
that suitable empirical likelihood ratio statistics each converge in distribution to a
2 random variable. Through simulation studies, we investigate the advantages of
this empirical likelihood approach compared to use of the usual normal approximation.
Two examples from previously published clinical studies illustrate the use of
the empirical likelihood methods we have described.
Empirical likelihood has obvious appeal in deriving point and interval estimators
for time-to-event data. However, when we use this method and its asymptotic
critical value to construct simultaneous confidence bands for survival or cumulative
hazard functions, it typically necessitates very large sample sizes to achieve reliable
coverage accuracy. We propose using a bootstrap method to recalibrate the critical
value of the sampling distribution of the sample log-likelihood ratios. Via simulation
studies, we compare our EL-based bootstrap estimator for the survival function
with EL-HW and EL-EP bands proposed by Hollander et al. (1997) and apply this
method to obtain a simultaneous confidence band for the cumulative hazard ratios
in the two clinical studies that we mentioned above.
While copulas have been a popular statistical tool for modeling dependent data
in recent years, selecting a parametric copula is a nontrivial task that may lead to
model misspecification because different copula families involve different correlation
structures. This observation motivates us to use empirical likelihood to estimate
a copula nonparametrically. With this EL-based estimator of a copula, we derive
a goodness-of-fit test for assessing a specific parametric copula model. By means
of simulations, we demonstrate the merits of our EL-based testing procedure. We
demonstrate this method using the data from Wieand et al. (1989).
In the final chapter of the thesis, we provide a brief introduction to several areas
for future research involving the empirical likelihood approach.

Abstract:
AbstractParastomal hernia is an incisional hernia resulting from an abdominal wall stoma creation [1]. The published incidence of parastomal hernia varies widely, with 2–28% and 4–48% affecting end ileostomies and end colostomies, respectively, depending on the severity of the hernia, method of diagnosis, and the duration of follow-up [2]. Loop stomas have a much lower incidence of parastomal herniation, as these tend to be reversed before a hernia can develop. The risk of herniation is cumulative with time but appears to be highest within 2 years of ostomy formation. Most patients are asymptomatic or have mild complaints such as intermittent discomfort or sporadic obstructive symptoms, but many eventually have symptoms significant enough to warrant surgical intervention, including incarceration, strangulation, and perforation. The bulging around the stoma can also cause result in difficulty applying the stoma appliance, resulting in leakage and skin irritation [2].

Abstract:
Worldwide, the cumulative annual disabilities and deaths due to neglected tropical diseases (NTDs) are in the millions, with most cases found in the low-income countries. The World Health Organization (WHO) has proposed a road map to eliminate NTDs by the year 2030. Core interventions being implemented to achieve this target are vaccinations, chemotherapeutic treatments, vector control, and practicing hygiene. Whereas multiple successes have been registered so far, inadequacies or the complete absence of diagnostics for some of the diseases being targeted, are however hampering ongoing eradication campaigns. Current diagnostics for NTDs are costly, require sophisticated gadgets, depend on electricity, are time consuming and labor intensive, have low detection/discriminatory power, or require trained personnel for operation. For these reasons, the use of such diagnostics is limited to only well-equipped laboratories, often inaccessible to the poor who are the most affected by the NTDs. To increase accessibility to diagnostics by those who need it the most, Rapid Diagnostic Tests (RDTs) are being developed by translating existing diagnostic technologies, or by invention of new technologies. Here, we reviewed conventional diagnostics for NTDs as well as their RDT translated formats, and explored nanobodies (Nbs) as alternative reagents for the development of the RDTs.

Abstract:
Abstract Psychotic illnesses are increasingly complicated by alcohol and drug abuse as patients no longer spend long periods in hospital. Treated in the community the benefits of social inclusion can be offset by greater exposure to drugs and alcohol. Dual diagnosis patients will be used throughout this chapter to refer to patients with a psychotic illness plus significant alcohol or substance abuse. Assertive outreach provides the opportunity to accept dual diagnosis patients and work towards resolving the cumulative problems that both conditions bring. Dual diagnosis carries additional problems for both patients and services. Integrating both substance abuse strategies and more traditional mental health interventions in the same team is an essential response for such chaotic individuals.

Abstract:
Abstract Pain in youth athletes is not synonymous with injury (tissue damage). Rather, youth athletes’ pain, be it nociceptive, neuropathic, or nociplastic, results from the cumulative impact of many biopsychosocial factors common to the youth athletic experience. Appropriate identification and correction of these factors is critical to optimal pain management in youth athletes, which should not be limited to the diagnosis and treatment of structural damage at the anatomic location of pain. This chapter provides a framework for the diagnosis and management of youth athletes’ pain that is informed by pain pathophysiology and biopsychosocial factors drawn from developmental, biomechanical, and psychosocial domains unique to the youth athlete.

Abstract:
Abstract Work-related musculoskeletal disorders comprise a heterogeneous group of conditions whose natural history is for the most part poorly understood. A variety of terms have been used in different ways. For some, ‘work-related upper limb disorders’, ‘cumulative trauma disorders’, and ‘repetitive strain disorders’ are synonymous and describe a range of conditions—some well defined, others less so—arising or appearing to arise from frequent overuse at work. For others, repetitive strain injury (RSI) refers to a particular diagnosis made by exclusion: chronic upper limb pain ascribed to overuse at work for which no clinical diagnosis can be made. The apparently simple question, ‘which musculoskeletal problems are work-related’, has proved difficult to answer. Study data are weakened by cross-sectional designs and by selection bias.

Abstract:
The polycystic ovary syndrome (PCOS) includes different clinical, endocrine, metabolic, and morphological criteria in women of reproductive age and consequently different health risks in later life of a woman. Controversy and debates related to diagnostic criteria are constant and current worldwide. As a result of many proposals for PCOS diagnostic criteria, clinicians recognize four phenotypes of PCOS. PCOS is a frequent cause of infertility with an overall prevalence of 5–15% and counts for approximately 70% of all cases of ovulation disorders. There are many aspects of studying differences between PCO phenotypes and problems in infertility treatments. Ovulation induction is often used to treat anovulatory patients with PCOS, but many of these women fail to conceive and the next step in the treatment is assisted reproduction. The contribution of oocyte health to reproductive potential varies and largely depends on the PCOS phenotype and comorbidities associated with PCOS. Contrary to the previous one, PCOS phenotype is not significantly associated with the morphological quality of oocytes. It seems that a combination of hyperandrogenism and chronic anovulation is associated with a negative impact on the cumulative pregnancy rate in medically assisted reproduction.

Abstract:
ECG is an important means of diagnosis of arrhythmia. In daily health monitoring, serious noise pollution, reverse leads connection, and so on make cannot meet the requirements of subsequent automatic diagnosis. Thus, it is of great significance to further evaluate the ECG quality and screen out the ECG that meet the requirements of subsequent diagnosis. However, complex interference factors affect the quality of the signal and has brought the huge challenge to quality assessment. Additionally, the current algorithms depend on the wave detection, which also brings additional cumulative error. Meanwhile, the current algorithms cannot intuitively present the attention degree to ECG signals during the assessment process. This paper proposes a novel method (ACNN) for evaluating the ECG quality. ACNN directly targets the whole ECG signal and does not detect the waveform of the ECG signal. Then, ACNN uses convolutional blocks to extract the deep features and designs a novel attention layer to enhance the beneficial features of the results. Finally, the fully connected layer is employed for obtaining the final quality evaluation. Compared with existing methods, ACNN obtains better performance, with 100.0% sensitivity, 83.33% specificity and 98.0% accuracy, which shows ACNN can be applied in clinical scenarios.

Abstract:
This paper presents a test, diagnosis, and rework analysis model for use in manufacturing process modeling. The approach includes a model of functional test operations characterized by fault coverage, false positives, and defects introduced in test, in addition to rework and diagnosis (diagnostic test) operations that have variable success rates and their own defect introduction mechanisms. The model accommodates multiple rework attempts on a product instance. The model is applied within a framework for optimizing the location(s) and characteristics (fault coverage/test cost, rework success rate/rework cost) of Test/Diagnosis/Rework (TDR) operations in a general manufacturing process. A new search algorithm called Waiting Sequence Search (WSS) is applied to traverse a general process flow to perform the cumulative calculation of a yielded cost objective function. Real-Coded Genetic Algorithms (RCGAs) are used to perform a multi-objective optimization that minimizes yielded cost. An example of a general complex process flow is used to demonstrate the feasibility of the algorithm.

In ASME 2012 Internal Combustion Engine Division Spring Technical Conference. American Society of Mechanical Engineers, 2012. http://dx.doi.org/10.1115/ices2012-81105.
Abstract:
Reciprocating engines are still frequently used in aviation especially in applications such as recreation planes, taxi-planes, fire extinguishing aircraft and generally applications that do not require a high power density. For such applications they have a significant advantage against turbine engines as far as purchase and maintenance cost is concerned. The proper and efficient operation of these engines in aviation applications is critical and therefore techniques that are used to determine engine condition and to detect potential faults are extremely important. The performance of these engines depends strongly on the condition of the ignition system and the quality of the supplied mixture. For this reason in the present work it is examined the effect of mixture AFR on the combustion mechanism and engine performance using an existing diagnostic methodology for spark ignited engines developed by the present research group. The investigation is conducted on a radial, spark-ignited reciprocating engine used on the CL-215 fire extinguishing aircraft. The diagnostic technique is used to investigate the effect of AFR on the main combustion and performance characteristics of the engine and specifically brake power output, rate of heat release, cumulative heat release, peak firing pressure, ignition and injection timing and duration of combustion. Furthermore the diagnostic technique is used to derive information for spark advance, spark duration, compression condition etc. The diagnostic technique is based on a thermodynamic two-zone combustion model for spark ignited engines. To examine the effect of AFR on the combustion mechanism a detailed experimental investigation was conducted on an engine (radial, supercharged, air-cooled, eighteen-cylinders) mounted on a test bench. The measurement procedure involved measurements at various operating conditions (load and speed) and various AFR values. During the experimental investigation beyond the conventional test bench measurements, measurements were taken using a fast data acquisition system of cylinder pressure and the electric signal of both spark plugs. Engine diagnosis is established by processing of these measured data. From the results of the diagnosis procedure it is revealed that the diagnosis method provides detailed information for the operating condition of the engine and the values of parameters that cannot be measured on the field. The diagnosis results reveal that the proposed technique can determine the effect of AFR ratio on the combustion mechanism adequately and thus it can be used during engine testing to determine the optimum AFR ratio in combination with the remaining engine settings and mainly spark advance. The results obtained are positive and reveal that the proposed diagnostic technique can be easily applied on any type of spark-ignited engine and especially on aircraft piston engines (i.e. aviation applications), where the accurate estimation of the engine condition and settings is extremely important.

Abstract:
Very Large Floating Structures, so-called Mega-Floats, are the kind of social infrastructures. They are generally expected to keep their integrity for a long period, for example, more than 100 years. So, it is necessary to develop Long-Term Integrity Prediction and Diagnosis System to diagnose the soundness of Mega-Floats. In the present study, we paid our attention to dolphin-fender type mooring devices that pontoon type VLFS are equipped with. As a part of Long-Term Integrity Prediction and Diagnosis System, we developed a long-term integrity prediction code (Cumulative Fatigue Damage Prediction Code) to predict damage of these dolphins. We made an at-sea experiment with pontoon type VLFS model of 201.5 [m] length, 100 [m] breadth, and 3 [m] depth (We call this “At-Sea Experiment for Verifying Functions of Mega-Float Information Data Center”). The model had two dolphin-fender type mooring devices and we applied Cumulative Fatigue Damage Prediction Code to these devices.

Agency for Healthcare Research and Quality (AHRQ), December 2022. http://dx.doi.org/10.23970/ahrqepccer258.
Abstract:
Objectives. Diagnostic errors are a known patient safety concern across all clinical settings, including the emergency department (ED). We conducted a systematic review to determine the most frequent diseases and clinical presentations associated with diagnostic errors (and resulting harms) in the ED, measure error and harm frequency, as well as assess causal factors. Methods. We searched PubMed®, Cumulative Index to Nursing and Allied Health Literature (CINAHL®), and Embase® from January 2000 through September 2021. We included research studies and targeted grey literature reporting diagnostic errors or misdiagnosis-related harms in EDs in the United States or other developed countries with ED care deemed comparable by a technical expert panel. We applied standard definitions for diagnostic errors, misdiagnosis-related harms (adverse events), and serious harms (permanent disability or death). Preventability was determined by original study authors or differences in harms across groups. Two reviewers independently screened search results for eligibility; serially extracted data regarding common diseases, error/harm rates, and causes/risk factors; and independently assessed risk of bias of included studies. We synthesized results for each question and extrapolated U.S. estimates. We present 95 percent confidence intervals (CIs) or plausible range (PR) bounds, as appropriate. Results. We identified 19,127 citations and included 279 studies. The top 15 clinical conditions associated with serious misdiagnosis-related harms (accounting for 68% [95% CI 66 to 71] of serious harms) were (1) stroke, (2) myocardial infarction, (3) aortic aneurysm and dissection, (4) spinal cord compression and injury, (5) venous thromboembolism, (6/7 – tie) meningitis and encephalitis, (6/7 – tie) sepsis, (8) lung cancer, (9) traumatic brain injury and traumatic intracranial hemorrhage, (10) arterial thromboembolism, (11) spinal and intracranial abscess, (12) cardiac arrhythmia, (13) pneumonia, (14) gastrointestinal perforation and rupture, and (15) intestinal obstruction. Average disease-specific error rates ranged from 1.5 percent (myocardial infarction) to 56 percent (spinal abscess), with additional variation by clinical presentation (e.g., missed stroke average 17%, but 4% for weakness and 40% for dizziness/vertigo). There was also wide, superimposed variation by hospital (e.g., missed myocardial infarction 0% to 29% across hospitals within a single study). An estimated 5.7 percent (95% CI 4.4 to 7.1) of all ED visits had at least one diagnostic error. Estimated preventable adverse event rates were as follows: any harm severity (2.0%, 95% CI 1.0 to 3.6), any serious harms (0.3%, PR 0.1 to 0.7), and deaths (0.2%, PR 0.1 to 0.4). While most disease-specific error rates derived from mainly U.S.-based studies, overall error and harm rates were derived from three prospective studies conducted outside the United States (in Canada, Spain, and Switzerland, with combined n=1,758). If overall rates are generalizable to all U.S. ED visits (130 million, 95% CI 116 to 144), this would translate to 7.4 million (PR 5.1 to 10.2) ED diagnostic errors annually; 2.6 million (PR 1.1 to 5.2) diagnostic adverse events with preventable harms; and 371,000 (PR 142,000 to 909,000) serious misdiagnosis-related harms, including more than 100,000 permanent, high-severity disabilities and 250,000 deaths. Although errors were often multifactorial, 89 percent (95% CI 88 to 90) of diagnostic error malpractice claims involved failures of clinical decision-making or judgment, regardless of the underlying disease present. Key process failures were errors in diagnostic assessment, test ordering, and test interpretation. Most often these were attributed to inadequate knowledge, skills, or reasoning, particularly in “atypical” or otherwise subtle case presentations. Limitations included use of malpractice claims and incident reports for distribution of diseases leading to serious harms, reliance on a small number of non-U.S. studies for overall (disease-agnostic) diagnostic error and harm rates, and methodologic variability across studies in measuring disease-specific rates, determining preventability, and assessing causal factors. Conclusions. Although estimated ED error rates are low (and comparable to those found in other clinical settings), the number of patients potentially impacted is large. Not all diagnostic errors or harms are preventable, but wide variability in diagnostic error rates across diseases, symptoms, and hospitals suggests improvement is possible. With 130 million U.S. ED visits, estimated rates for diagnostic error (5.7%), misdiagnosis-related harms (2.0%), and serious misdiagnosis-related harms (0.3%) could translate to more than 7 million errors, 2.5 million harms, and 350,000 patients suffering potentially preventable permanent disability or death. Over two-thirds of serious harms are attributable to just 15 diseases and linked to cognitive errors, particularly in cases with “atypical” manifestations. Scalable solutions to enhance bedside diagnostic processes are needed, and these should target the most commonly misdiagnosed clinical presentations of key diseases causing serious harms. New studies should confirm overall rates are representative of current U.S.-based ED practice and focus on identified evidence gaps (errors among common diseases with lower-severity harms, pediatric ED errors and harms, dynamic systems factors such as overcrowding, and false positives). Policy changes to consider based on this review include: (1) standardizing measurement and research results reporting to maximize comparability of measures of diagnostic error and misdiagnosis-related harms; (2) creating a National Diagnostic Performance Dashboard to track performance; and (3) using multiple policy levers (e.g., research funding, public accountability, payment reforms) to facilitate the rapid development and deployment of solutions to address this critically important patient safety concern.
