Elektrokardiografinių rodiklių, ypač jų tarpusavio sąsajų kaitos tyrimas ir jų vertinimas naujais matematiniais analizės metodais – tai naujos galimybės praktiniam kompleksinių sistemų teorijos pritaikymui, siekiant atskleisti kurortinių veiksnių sukeliamus efektus. Bendrosios krioterapijos ir peloidoterapijos (gydomojo purvo vonios) procedūrų metu buvo nepertraukiamai registruota 12-os derivacijų EKG ir vertinta EKG rodiklių kaita šių procedūrų metu. Pritaikius naują matematinės analizės metodiką, sudarant dviejų procesų matricas ir išskaičiuojant diskriminantą, buvo vertinta EKG rodiklių dinaminių sąsajų kaita bei žmogaus organizmo funkcijų kompleksiškumos pokyčiai, vykstantys bendrosios krioterapijos ir peloidoterapijos procedūrų metu. Taip pat buvo vertintas organizmo jautrumo šalčio poveikiui ir adaptacinių organizmo reakcijų kitimas pakartotinių bendrosios krioterapijos poveikių metu. Pagal širdies ritmo variabilumo kitimą peloidoterapijos procedūrų metu buvo lygintos skirtingo amžiaus ir lyties žmonių adaptacinės organizmo reakcijos ir organizmo funkcijų kompleksiškumas. Šis tyrimas atskleidė net ir nedidelius reakcijų ypatumus ir skirtumus, kurių nebūtų galima pastebėti tiriant įprastinės elektrokardiografijos būdu. Toks tyrimo metodas ateityje galėtų būti plačiai taikomas kurortologiniuose tyrimuose, ypač diegiant naujas procedūras, tiriant ir lyginant gydymui taikomų procedūrų sukeltus efektus bei modeliuojant grįžtamąjį ryšį. / Research of electrocardiographic parameters, especially changes of their concatenations and assessment using new methods of mathematical analysis is a new opportunity to practically apply complex systems theory in order to reveal the effects, caused by factors of health resorts. The standard 12-lead ECG was registered synchronously and continuously through the procedures of whole body cryotherapy and peloidotherapy (mud baths) and changes of ECG parameters during these procedures were evaluated. A new mathematical analysis method, which consists of creating matrices of two processes and deducting a discriminant, was used to evaluate changes of dynamical concatenations of ECG parameters and functional changes of human organism’s complexity, which take place during general cryotherapy and peloidotherapy procedures. Organism’s sensitivity to cold and changes of adaptive reactions during repeated exposure to this factor during general cryotherapy was also assessed. Adaptive reactions and complexity of functioning of the organism within groups of various age and gender were compared according to the changes of heart rate variability. This research has revealed even small specificities and differences of reactions, which could not be identified by employing conventional electrocardiography. This test method could be widely applied in future researches in the field of health resort, particularly when introducing new procedures, researching or comparing treatment-induced effects...

Background: Hereditary transthyretin amyloidosis (ATTR) is a lethal disease in which misfolded transthyretin (TTR) proteins accumulate as insoluble aggregates in tissues throughout the body. A common mutation is the exchange of valine to methionine at place 30 (TTR V30M), a form endemically found in the northern parts of Sweden. The main treatment option for ATTR amyloidosis is liver transplantation as the procedure halts production of mutated transthyretin. The disease is associated with marked phenotypic diversity ranging from predominant cardiac complications to pure neuropathy. Two different types of fibril composition – one in which both fragmented and full-length TTR are present (type A) and one consisting of only full-length TTR (type B) have been suggested to account for some phenotypic differences. Cardiac amyloidosis is associated with increased myocardial thickness and the disease could easily be mistaken for other entities characterised by myocardial thickening, such as sarcomeric hypertrophic cardiomyopathy (HCM). The aims in this thesis were to investigate echocardiographic characteristics in Swedish ATTR amyloidosis patients, and to identify markers aiding in differentiating ATTR heart disease from HCM. Another objective was to examine the impact of fibril composition and sex on the phenotypic variation in amyloid heart disease. Methods: A total of 122 ATTR amyloidosis patients that had undergone thorough echocardiographic examinations were included in the studies. Analyses of ventricular geometry as well as assessment of systolic and diastolic function were performed, using both conventional echocardiographic methods and speckle tracking technique. ECG analysis was conducted in study I, allowing measurement of QRS voltage. In study I and study II ATTR patients were compared to patients with HCM. In addition, 30 healthy controls were added to study II. Results: When parameters from ECG and echocardiography were investigated, the results revealed that the combination of QRS voltage <30 mm (<3 mV) and an interventricular/posterior wall thickness quotient <1.6 could differentiate cardiac ATTR amyloidosis from HCM. Differences in degree of right ventricular involvement were also demonstrated between HCM and ATTR amyloidosis, where ATTR patients displayed a right ventricular apical sparing pattern whereas the inverse pattern was found in HCM. Analysis of fibril composition revealed increased LV wall thickness in type A patients compared to type B, but in addition type A women displayed both lower myocardial thickness and more preserved systolic function as compared to type A males. When cardiac geometry and function were evaluated pre and post liver transplantation in type A and B patients, significant deterioration was detected in type A but not in type B patients after liver transplantation. Conclusions: Increasing awareness of typical cardiac amyloidotic signs by echocardiography is important to reduce the risk of delayed diagnosis. Our classification model based on ECG and echocardiography could aid in differentiating ATTR amyloidosis from HCM. Furthermore, the apical sparing pattern found in the right ventricle may pose another clue for amyloid heart disease, although it requires to be studied further. Furthermore, we disclosed that type A fibrils, male sex and increasing age were important determinants of increased myocardial thickness. As type A fibril patients displayed rapid cardiac deterioration after liver transplantation other treatment options should probably be sought for this group of patients.

In all mammalian species examined thus far, the ovaries produce a burst of ornithine decarboxylase (ODC) and putrescine during ovulation or after application of a bolus of human chorionic gonadotropin (hCG). Aged mice are deficient in this peri-ovulatory ODC and putrescine burst. Moreover, peri-ovulatory putrescine supplementation in aged mice increases egg quality and reduces miscarriage rates. These studies suggest that peri-ovulatory putrescine supplementation may be a simple and effective therapy for reproductive aging for women. However, putrescine has never been used in humans and, currently no pure source of putrescine is suitable for human trials. Given that ODC is highly expressed in the ovaries during ovulation but otherwise exhibits low activity in most tissues, we hypothesized that L-ornithine, the substrate of ODC, might be a better alternative. In this study, we have demonstrated that systemic application of L-ornithine increased ovarian putrescine levels; the increase was restricted to animals that had been injected with hCG. Furthermore, L-ornithine specifically increased ovarian putrescine levels without affecting putrescine levels in most other tissues. Unfortunately, thus far peri-ovulatory L-ornithine supplementation in mouse drinking water produced mixed effects on reproductive outcome in aged mice. Therefore, our studies demonstrated the potential of L-ornithine supplementation as a possible therapy for aging-related infertility, but further work is required to produce an effective application method.

An integration of ICT advances into a conventional healthcare system is spreading extensively nowadays. This trend is known as Electronic health or E-Health. E-Health solutions help to achieve the sustainability goal of increasing the expected lifetime while improving the quality of life by providing a constant healthcare monitoring. Cardiovascular diseases are one of the main killers yearly causing approximately 17.7 million deaths worldwide. The focus of this work is on studying the detection of one of the cardiovascular diseases – Atrial Fibrillation (AF) arrhythmia.  This type of arrhythmia has a severe influence on the heart health conditions and could cause congestive heart failure (CHF), stroke, and even increase the risk of death. Therefore, it is important to detect AF as early as possible. In this thesis we focused on studying various machine learning techniques for AF detection using only short single lead Electrocardiography recordings. A web-based solution was built as a final prototype, which first simulates the reception of a recorded signal, conducts the preprocessing, makes a prediction of the AF presence, and visualizes the result. For the AF detection the relatively high accuracy score was achieved comparable to the one of the state-of-the-art. The work was based on the investigation of the proposed architectures and the usage of the database of signals from the 2017 PhysioNet/CinC Challenge. However, an additional constraint was introduced to the original problem formulation, since the idea of a future deployment on the resource-limited devices places the restrictions on the complexity of the computations being performed for achieving the prediction. Therefore, this constraint was considered during the development phase of the project.

Artificial neural networks have been gaining attention in recent years due to theirimpressive ability to map out complex nonlinear relations within data. In this report,an attempt is made to use a Long short-term memory neural network for detectinganomalies within electrocardiographic records. The hypothesis is that if a neuralnetwork is trained on records of normal ECGs to predict future ECG sequences, it isexpected to have trouble predicting abnormalities not previously seen in the trainingdata. Three different LSTM model configurations were trained using records fromthe MIT-BIH Arrhythmia database. Afterwards the models were evaluated for theirability to predict previously unseen normal and anomalous sections. This was doneby measuring the mean squared error of each prediction and the uncertainty of over-lapping predictions. The preliminary results of this study demonstrate that recurrentneural networks with the use of LSTM units are capable of detecting anomalies.

Os cães foram divididos em três grupos de acordo com o número de extrassístoles ventriculares (EV) obtidas pela avaliação Holter. O GC foi composto por cães apresentando menos de 20 EV/24 horas, o GD1 foi formado por animais com mais de 100 e menos de 1.000 EV/24 horas, enquanto o GD2 foi composto por animais que apresentaram mais de 1.000 EV/24 horas. Levando em consideração a presença de EV e extrassístoles supraventriculares (ESV) no ECG, este teste apresentou 83,33% de sensibilidade, 100% de especificidade, valor preditivo positivo (VPP) de 100% e valor preditivo negativo (VPN) de 86%. Os parâmetros da VFC SDNNIDX (Gc: 194,08 ± 56,29 ms; GD1: 202,20 ± 94,79 ms; GD2: 118,00 ± 43,76 ms) e pNN>50 (Gc: 39,75 ± 12,69 ms; GD1: 46,24 ± 14,08; GD2: 21,52 ± 9,27 ms) foram significativamente menores nos pacientes do GD2. O ECGAR apresentou sensibilidade de 30%, especificidade de 50%, VPP de 37,5% e VPN de 41,67%. Assim, os resultados sugerem que a eletrocardiografia convencional e a VFC são técnicas que podem contribuir substancialmente no diagnóstico da CAVD em cães Boxers, ao contrário da eletrocardiografia de alta resolução que se mostrou ineficaz em identificar a presença de potenciais tardios nos pacientes com esse grau de doença / Aiming to investigate the importance of tools that could identify arrhythmias or detect its possible inciting factor in patients affected by arrhythmogenic right ventricular cardiomyopathy, 25 Boxer dogs were submitted to conventional electrocardiogram (ECG), heart rate variability (HRV), obtained by 24-hours Holter evaluation, and 20 were submitted to high resolution electrocardiogram (HRECG). Dogs were divided into three different groups according to the number of ventricular complexes (VC) obtained in Holter analysis. The GC was formed by dogs presenting less than 20 VC/24 hours, the GD1 was formed by animals presenting more than 100 and less than 1.000 VC/24 hours, while the GD2 was composed of dogs presenting over a 1.000 VC/24 hours. Considering the presence of ventricular or supraventricular complexes on the ECG, this test had 83,33% of sensitivity, 100% of specificity, positive predictive value (PPV) of 100% and negative predictive value (NPV) of 86%. The HRV parameters SDNNIDX (Gc: 194.08 ± 56.29 ms; GD1: 202.20 ± 94.79 ms; GD2: 118.00 ± 43.76 ms) and pNN>50 (Gc: 39.75 ± 12.69 ms; GD1: 46.24 ± 14.08; GD2: 21.52 ± 9.27 ms) were significantly lower in the patients of GD2. The HRECG showed 30% of sensitivity, 50% of specificity, PPV of 37,5% and NPV of 41,67%. Thus, the results suggest that conventional ECG and HRV are techniques that can strongly contribute in the diagnosis of ARVD in Boxer dogs, opposed to HRECG that showed itself inefficient to detect the presence of late potentials in patients with this degree of disease

Nas últimas décadas, suas populações têm sofrido declínio notório devido, principalmente, à destruição do seu habitat. Isto causa a perda da diversidade genética, que junto à depressão endogâmica (pelo isolamento de pequenas populações) pode levar à espécie a extinções locais. Nesse contexto, as técnicas de reprodução assistida podem auxiliar no processo de manutenção da diversidade genética nestas populações isoladas. Desta forma, o objetivo deste estudo foi elaborar um protocolo de superovulação para cervo-do-pantanal em cativeiro. Assim, foram testados protocolos sucessivamente (A, B, C) até que fossem obtidos resultados satisfatórios. Para que se pudesse chegar a um protocolo viável, foram testadas três combinações farmacológicas. Tratamento A: CIDR® durante sete dias, seguido de 0,5 mg de BE e 0,11 mg de GnRH no dia 0, 800UI de eCG no dia 5 após inserção do CIDR®, 530 µg de PGF2α no dia 7 e 0,11 mg de GnRH logo após a detecção do estro, para a indução da ovulação. Tratamento B: CIDR® durante oito dias, seguido de 0,5 mg de BE e 0,11 mg de GnRH no dia 0, 1200UI de eCG no dia 5 após inserção do CIDR®, 530 µg de PGF2α no dia 8 e 0,11 mg de GnRH logo após a detecção do estro, para a indução da ovulação. Tratamento C: CIDR® durante oito dias, seguido de 0,5 mg de BE e 0,11 mg de GnRH no dia 0, 1200UI de eCG no dia 5 após inserção do CIDR®, 530 µg de PGF2α no dia 8 e 2,5 mg de LH, entre 12-18 horas após a detecção do estro para a indução da ovulação. A detecção de estro foi realizada com o auxílio de um macho, sendo permitida a cópula. Oito dias após a cópula foi realizada a contagem dos CL e folículos anovulatórios mediante laparotomia mediana ventral, assim como a colheita de embriões. O Tratamento A resultou em 2 CL. O Tratamento B resultou em 1 CL e 8 folículos anovulatórios. O Tratamento C resultou em 10, 3 e 11 CL, e 0, 1 e 5 folículos anovulatórios para as fêmeas 3, 4 e 5, respectivamente. Além disso foi realizada a colheita de 2, 2 e 5 embriões das fêmeas FBD3, FBD4 e FBD5, respectivamente. Obtendo uma taxa de recuperação de 37,5% (9/24), dos quais dois eram embriões viáveis para transferência. Todos os tratamentos foram efetivos na sincronização do estro. O Tratamento C, com a aplicação i.m. de 1200UI de eCG e de LH, como indutor da ovulação, teve a melhor resposta em termos de superovulação, assim como de colheita de embriões. / The marsh deer (Blastocerus dichotomus) is an emblematic species within the neotropical deer. In the last decades, their populations have suffered a notable decline due, mainly, to the destruction of their habitat. This causes loss of genetic diversity, which together with inbreeding depression (by the isolation of many small populations) can lead this species to local extinctions. In this context, assisted reproduction techniques can help in the process of maintaining genetic diversity in these isolated populations. Thus, the aim of this study was to elaborate a superovulation protocol for captive marsh deer. Therefore, protocols were successively tested (A, B, C) until satisfactory results were obtained. To be able to achieve a viable protocol, three pharmacological combination were tested. Treatment A: CIDR® for 7 days, followed by 0.5 mg of EB and 0.11 mg of GnRH on D0, 800IU of eCG on day 5 after CIDR® insertion, 530 µg PGF2α on day 7, and 0.11 mg of GnRH soon after estrus detection, for ovulation induction. Treatment B: CIDR® for 8 days, followed by 0.5 mg of EB and 0.11 mg of GnRH on D0, 1200IU of eCG on day 5 after CIDR® insertion, 530 µg PGF2α on day 8, and 0.11 mg of GnRH soon after estrus detection, for ovulation induction. Treatment C: CIDR® for 8 days, followed by 0.5 mg of EB and 0.11 mg of GnRH on D0, 1200IU of eCG on day 5 after CIDR® insertion, 530 µg PGF2α on day 8, and 0.25 mg of LH, between 12-18 hours post estrus detection, for ovulation induction. Estrus detection was performed with the aid of a male, and copulation was allowed. Eight days after copulation, CL and anovulatory follicles were counted through median ventral laparotomy, as well as the collection of embryos. Treatment A resulted in 2 CL. Treatment B resulted in 1 CL and 8 anovulatory follicles. Treatment C resulted in 10, 3 and 11 CL, and 0, 1 and 5 anovulatory follicles for hinds FBD3, FBD4, and FBD5, respectively. In addition, 2, 2 and 5 embryos were harvested from hinds FBD3, FBD4 and FBD5, respectively. Obtaining a recovery rate of 37.5% (9/24), of which two were viable embryos for transfer. All treatments were effective in synchronizing estrus. Treatment C, with an i.m. application of 1200IU of eCG and LH, as ovulation inducer, had the best response in terms of superovulation, as well as embryo collection.
