The main concern of this work is to offer an analysis of the possibility of an ethical approach to the interaction between human beings and animals. As far as possible we seek an approach which rely neither on utilitarian considerations nor on indirect reasons to explain the attribution of dignity or moral rights to animals. We take for granted that some of them (if not all) do possess it. And then we try to show that a deontological ethical theory (one which centers in the human as the agent but is not restricted to humans as the objects of the moral action) can afford us a good theoretical basis for the grounding of the attribution of rights or dignity to animals. Analyzing the main features of Kantian ethics, as well as some of its alternatives, it will be possible to show that an ethical theory which does not presuppose reciprocity nor depends solely upon particular human concerns is not only possible but also reveals itself as the most sensible and adequate to the nature of our values and of the case at hand.

Photodynamic therapy (PDT) consists of a non-toxic photosensitizing agent (FS) administration followed by a laser source resulting in a sequence of photochemical and photobiological processes that generate reactive oxygen species (ROS) that damaging cells. The present work evaluated the effects of PDT nanoemulsion-aluminum chloride phthalocyanine (AlClFc) mediated on malondialdehyde (MDA), glutathione (GSH), superoxide dismutase (SOD) and glutathione peroxidase (GPx) levels, which represent indicators involved in oxidative stress and antioxidant defenses. For this purpose, this study used 120 female rats of the Rattus norvegicus species, Wistar race, divided into 5 groups: Healthy (H), with periodontal disease (PD), with periodontal disease and treatment with FS (F), with periodontal disease and treatment with the laser (L); and periodontal disease and treatment with PDT (FL). An experimental model for represent periodontal disease (PD) was induced by ligature (split-mouth). Seven days later the induction of PD, the treatments were instituted according to the groups. In the group treated with PDT was applied 40μl FS (5μM) followed by laser irradiation diode InGaAlP (660nm, 100J / cm2). The rats were sacrificed on the 7th and 28th day after treatment and tissue specimens were removed and subjected to histological, immunohistochemical methods and enzymatic colorimetric measurements with detection by UV / VIS spectroscopy. Inflammatory changes, connective tissue disorganization and alveolar bone loss were displaying in groups with PD induced. The enzyme dosages showed that MDA levels were higher in PD induced groups, with no statistically significant differences (p> 0.05). High levels of GSH were found in groups L (p = 0.028) and FL (p = 0.028) compared with PD group, with statistically significant differences. Immunohistochemistry for SOD showed higher immunostaining in L and FL groups, compared to the PD group without statistically significant differences (p> 0.05). GPx showed lower immunoreactivity in the DP group when compared to the other groups and statistically significant differences were observed between the DPxL groups (p <0.05). TFD administered in this experiment did not induce elevation of MDA levels significantly increased the GSH levels and showed intense immunostaining pada SOD and GPx, showing that this therapy does not accentuated lipid peroxidation, however, it was able to induce effects on the antioxidant defenses processes. The LBI therapy appeared to show photomodulatory promoting effects reduction of the MDA levels, increasing GSH levels and with intense immunostaining for SOD and GPx, demonstrating that laser therapy induced antioxidant effects.

Introduction: The production of KPC (Klebsiella pneumoniae carbapenemase) has become an important mechanism of carbapenem-resistance among Enterobacteriaceae strains. In Brazil, KPC is already widespread and its incidence has increased significantly, reducing treatment options. The “perfect storm” combination of the absence of new drug developmentand the emergence of multidrug-resistant strains resulted in the need for the use of older drugs, with greater toxicity, such as polymyxins. Aims: To determine the occurrence of carbapenemase-producing strains in carbapenem-resistant Enterobacteriaceae isolated from patients with nosocomial infection/colonization during September/2014 to August/2015, to determine the risk factors associated with 30-day- mortality and the impact of inappropriate therapy. Materials and Methods: We performed a case control study to assess the risk factors (comorbidities, invasive procedures and inappropriate antimicrobial therapy) associated with 30-day-mortality, considering the first episode of infection in 111 patients. The resistance genes blaKPC, blaIMP, blaVIM and blaNDM-1 were detected by polymerase chain reaction technique. Molecular typing of the strains involved in the outbreak was performed by pulsed field gel electrophoresis technique. The polymyxin resistance was confirmed by the microdilution broth method. Results: 188 episodes of carbapenem-resistant Enterobacteriaceae infections/colonizations were detected; of these, 122 strains were recovered from the hospital laboratory. The presence of blaKPC gene were confirmed in the majority (74.59%) of these isolates. It was not found the presence of blaIMP , blaVIM and blaNDM-1 genes. K. pneumoniae was the most frequent microorganism (77,13%), primarily responsible for urinary tract infections (21,38%) and infections from patients of the Intensive Care Unit (ICU) (61,38%). Multivariate statistical analysis showed as predictors independently associated with mortality: dialysis and bloodstream infection. The Kaplan-Meier curve showed a lower probability of survival in the group of patients receiving antibiotic therapy inappropriately. Antimicrobial use in adult ICU varied during the study period, but positive correlation between increased incidence of strains and the consumption was not observed. In May and July 2015, the occurrence rates of carbapenem-resistant Enterobacteriaceae KPC-producing per 1000 patient-days were higher than the control limit established, confirming two outbreaks, the first caused by colistin-susceptible KPC-producing K. pneumoniae isolates, with a polyclonal profile and the second by a dominant clone of colistin-resistant (≥ 32 μg/mL) KPC-producing K. pneumoniae. The cross transmission between patients became clear by the temporal and spatial relationships observed in the second outbreak, since some patients occupied the same bed, showing problems in hand hygiene adherence among healthcare workers and inadequate terminal disinfection of environment. The outbreak was contained when the ICU was closed to new admissions. Conclusions: The study showed an endemicity of K. pneumoniae KPC-producing in adult ICU, progressing to an epidemic monoclonal expansion, resulted by a very high antibiotic consumption of carbapenems and polymyxins and facilitated by failures in control measures the unit.

Advances in neonatology resulted in reducing the mortality rate and the consequent increase in survival of newborn pre terms (PTN). On the other hand, there was also a considerable increase in the risk of developing health care-related infection (HAI) in its most invasive, especially for bloodstream. This situation is worrying, and prevent the occurrence of it is a challenge and becomes one of the priorities in the Neonatal Intensive Care Unit (NICU). Sepsis is the main cause of death in critical neonates and affects more than one million newborns each year, representing 40% of all deaths in neonates. The incidence of late sepsis can reach 50% in NICUs. Currently the major responsible for the occurrence of sepsis in developed countries is the coagulase negative Staphylococcus (CoNS), followed by S. aureus. The cases of HAIs caused by resistant isolates for major classes of antimicrobial agents have been increasingly frequent in the NICU. Therefore, vancomycin has to be prescribed more frequently, and, today, the first option in the treatment of bloodstream infections by resistant Staphylococcus. The objectives of this study were to assess the impact on late sepsis in epidemiology III NICU after the change of the use of antimicrobials protocol; check the frequency of multiresistant microorganisms; assess the number of neonates who came to death. This study was conducted in NICU Level III HC-UFU. three study groups were formed based on the use of the proposed late sepsis treatment protocol, with 216 belonging to the period A, 207 B and 209 to the C. The work was divided into three stages: Period A: data collected from neonates admitted to the unit between September 2010 to August 2011. was using treatment of late sepsis: with oxacillin and gentamicin, oxacillin and amikacin, oxacillin and cefotaxime. Period B: data were collected from March 2012 to February 2013. Data collection was started six months after protocol change. Due to the higher prevalence of CoNS, the initial protocol was changed to vancomycin and cefotaxime. Period C: data were collected from newborns inteerne in the unit from September 2013 to August 2014. Data collection was started six months after the protocol change, which occurred in March 2013. From the 632 neonates included in this study, 511 (80,8%) came from the gynecology and obstetrics department of the HC-UFU. The mean gestational age was 33 weeks and the prevailing sex was male (55,7%). Seventy-nine percent of the studied neonates were hospitalized at the NICU HC-UFU III because of complications related to the respiratory system. Suspicion of sepsis took to hospitalization in the unit of 1,9% of newborns. In general, the infection rate was 34,5%, and the most frequent infectious sepsis syndrome 81,2%. There was a tendency to reduce the number of neonates who died between periods A 11 and C (p = 0,053). From the 176 cases of late sepsis, 73 were clinical sepsis and 103 had laboratory confirmation, with greater representation of Gram positive bacteria, which corresponded to 67.2% of the isolates and CoNS the most frequent micro-organism (91,5%). There was a statistically significant difference in the reduction of isolation of Gram positive microorganisms between periods A and C (p = 0,0365) as well as in reducing multidrug-resistant CoNS (A and B period p = 0,0462 and A and C period, p = 0,158). This study concluded that: the CoNS was the main microorganism responsible for the occurrence of late sepsis in neonates in the NICU of HC-UFU; the main risk factors for the occurrence of late sepsis were: birth weight <1500 g, use of PICC and CUV, need for mechanical ventilation and parenteral nutrition, SNAPPE> 24 and length of stay more than seven days; the new empirical treatment protocol late sepsis, based on the use of vancomycin associated cefepime, it was effective, since promoted a reduction in insulation CoNS blood cultures between the pre and post implementation of the Protocol (A and C, respectively); just as there was a reduction in the number of newborns who evolved to death between periods A and C.

Recolher dados para actualizar os conhecimento da diversidade parasitária dos mesocarnívoros mais abundantes nas regiões do sul de Portugal e relacionar a dispersão parasitária, a conservação e a saúde humana constituíram os principais objetivos deste estudo. Raposas (Vulpes vulpes), sacarrabos (Herpestes ichneumon), fuinhas (Martes foina), ginetes (Genetta genetta) e texugos (Meles meles) atropelados foram os carnívoros-hospedeiros em estudo. Um grupo de raposas caçadas foi também considerado parte da amostra. A informação geo-referenciada de todos os animais serviu para executar a análise espacial. Realizaram-se necrópsias meticulosas e procedeu se à recolha, identificação e preservação dos parasitas encontrados. Pela primeira vez em Portugal é registada a presença do parasita da gineta Ancytostoma martinezi. A correlação entre os factores humanos e ambientais e, a riqueza de espécies foi determinada estatisticamente. Densidade populacional, disponibilidade de égua, tipo de uso de solo e distância mínima às sedes de concelho não apresentaram uma relação estatisticamente significativa com a infecção parasitária das raposas. Os resultados obtidos relativamente à presença de parasitas zoonóticos nos animais silvestres em estudo fomentam o trabalho multidisciplinar entre a Biologia da Conservação e as ciências médicas. ABSTRACT; The aim of this study was to collect data in order to update the information related to the parasitic diversity of the predominant mesocarnívores in the southern regions of Portugal and to establish relationships between the parasite dispersal, conservation and human health. Road killed foxes (Vulpes vulpes), mongoose (Herpestes ichneumon), stone marten (Martes foina), common genets (Genetta genetta) and euroasian badgers (Meles meles) were the considered carnivore-hosts. A sample of hunted foxes was also regarded.AD the animals had geo-reference information, ultimately used for spatial analysis. Thorough necropsies were performed and macroparasites collected, identified and preserved. For the first time in Portugal Ancylostoma martinezi, a common genets parasite.is recorded. Statistical species richness and correlation between human and environmental factors were determined. Human population density, water drainage, soil use, minimum distance to head council cities and the infection status of foxes proved no significant statistical relation. Results obtained on zoonotic parasites present in wild animals enhance the necessity of multidisciplinary work between Biology conservation and medical sciences.

Este relatório foi realizado no âmbito da conclusão do mestrado integrado em medicina veterinária da Universidade de Évora, encontrando-se dividido em duas partes. A primeira é referente à casuística acompanhada ao longo do estágio curricular, decorrido no Hospital Veterinário do Restelo (HVR), com a duração de quatro meses, desde 03 de Agosto de 2015 a 06 de Dezembro de 2016, sob orientação da Doutora Sandra Branco e coorientação do Dr. Diogo Magno, subdiretor clínico do HVR. A segunda parte é constituída por uma monografia subordinada ao tema “Erliquiose Monocítica Canina”, seguida de um caso clínico acompanhado pelo autor no âmbito do referido tema. A erliquiose monocítica canina (EMC) é uma doença infeciosa transmitida por um vetor, o ixodídeo Riphicephalus sanguineus, cujos controlos químicos e ambientais são essenciais para reduzir a prevalência da doença. É causada por uma bactéria intracelular, Ehrlichia canis, que afeta o sistema imunitário dos cães, manifestando diferentes fases de evolução e podendo apresentar formas aguda e crónica da doença. O tratamento de primeira escolha é o uso da antibioterapia com tetraciclinas, dentre as quais a doxiciclina, para além do tratamento de suporte, como a fluidoterapia. O prognóstico é variável, dependendo da precocidade e eficiência da terapêutica instituída; ABSTRACT: The present report, wrote to get the master degree in veterinary medicine area, on Universidade de Évora, is divided up into two distinct parts. On one hand it describes the clinical situations’ roll, assisted through the experimental trainee, that took place on Hospital Veterinário do Restelo (HVR), for a period of four months, specifically since 3 august 2015 until 6 december 2015, and this trainee was led by Doctor Sandra Branco, and also the HVR’s clinical subdirector Dr. Diogo Magno. On other hand the second parts reveals a monograph titled “ehrlichiosis monocytic canine” (EMC), specifying a particular clinical case followed by the author. The EMC an infectious disease transmitted by a tick - Riphicephalus sanguineus – whose chemical controls and even the environmental ones are crucial to reduce the disease’s prevalence. The disease has an intracellular bacteria origin - Ehrlichia canis – responsability for the dog’s immune system infection, and it reveals different evolution phases and present acute or in some cases chronic forms. The treatment’s first step is to use an antibiotic with tetracycline that include doxycycline, and as a fluid’s therapy addition is use to do the supportive treatment. The diagnosis is variable so it depends on precocity evaluation and even on the therapeutics efficiencies.

Este relatório foi realizado no âmbito do estágio curricular no Hospital Veterinário do Baixo Vouga de 1 de Setembro de 2015 a 31 de Janeiro de 2016. A primeira componente trata da casuística acompanhada no estágio. A área médica mais comum foi a gastroenterologia. A segunda componente consiste na revisão bibliográfica da aspergilose canina complementada com um caso clínico acompanhado no estágio. A aspergilose sino-nasal canina ocorre principalmente em indivíduos jovens ou de meia-idade, mesaticéfalos ou dolicocéfalos e saudáveis. O seu diagnóstico implica o conjunto de vários exames, nomeadamente imagiológicos, cultura de fungos, histopatologia, serologia e diagnóstico molecular. O tratamento recomendado é o tópico. A aspergilose disseminada é menos frequente, sendo mais comum na raça Pastor Alemão. Sendo geralmente mais grave, o tratamento passa essencialmente pela terapia antifúngica sistémica. O uso de fungicidas tem sido muito associado à ocorrência de resistências cruzadas a antifúngicos azóis, dificultando o tratamento destas infeções; Abstract: Small Animal Medicine This report was elaborated following a traineeship at the Hospital Veterinário do Baixo Vouga from September 1st, 2015 to January, 31st, 2016. The first component covers the casuistry accompanied during the same. The most prevalent medical field was the gastroenterology. The second component consists of a literature review of canine aspergillosis along with the report of a case followed during the internship. Canine sinonasal aspergillosis primarily affects young to middle-aged, mesaticephalic or dolichocephalic and healthy dogs. Its diagnosis involves a conjunction of medical exams, namely imagiologic, fungal culture, histopathology, serology and molecular diagnosis. The recommended treatment is the topical one. Disseminated aspergillosis is more infrequent, occurring usually in German Shepard Dogs. Being more grievous, its treatment is based upon the administration of systemic antifungals. The use of azole fungicides has been linked to the development of cross-resistances between these and the antifungal azoles, making it difficult to treat such infections.
