An increasingly older population will most likely lead to greater demands on the health care system, as older age is associated with an increased risk of having acute and chronic conditions. The number of diseases or disabilities is not the only marker of the amount of health care utilized, as persons may seek hospitalization without a disease and/or illness that requires hospital healthcare. Hospitalization may pose a severe risk to older persons, as exposure to the hospital environment may lead to increased risks of iatrogenic disorders, confusion, falls and nosocomial infections, i.e., disorders that may involve unnecessary suffering and lead to serious consequences. Aims: The overall aim of this thesis was to describe and explore individual trajectories of cognitive development in relation to hospitalization and risk factors for hospitalization among older persons living in different accommodations in Sweden and to explore older persons' reasons for being transferred to a hospital. Methods: The study designs were longitudinal, prospective and descriptive, and both quantitative and qualitative methods were used. Specifically, latent growth curve modelling was used to assess the association of cognitive development with hospitalization. The Cox proportional hazards regression model was used to analyse factors associated with hospitalization risk overtime. In addition, an explorative descriptive design was used to explore how home health care patients experienced and perceived their decision to seek hospital care. Results: The most common reasons for hospitalization were cardiovascular diseases, which caused more than one-quarter of first hospitalizations among the persons living in ordinary housing and nursing home residents (NHRs). The persons who had been hospitalized had a lower mean level of cognitive performance in general cognition, verbal, spatial/fluid, memory and processing speed abilities compared to those who had not been hospitalized. Significantly steeper declines in general cognition, spatial/fluid and processing speed abilities were observed among the persons who had been hospitalized. Cox proportional hazards regression analysis showed that the number of diseases, number of drugs used, having experienced a fall and being assessed as malnourished according to the Mini Nutritional Assessment scale were related to an increased hospitalization risk among the NHRs. Among the older persons living in ordinary housing, the risk factors for hospitalization were related to marital status, i.e., unmarried persons and widows/widowers had a decreased hospitalization risk. In addition, among social factors, receipt of support from relatives was related to an increased hospitalization risk, while receipt of support from friends was related to a decreased risk. The number of illnesses was not associated with the hospitalization risk for older persons in any age group or for those of either sex, when controlling for other variables. The older persons who received home health care described different reasons for their decisions to seek hospital care. The underlying theme of the home health care patients’ perceptions of their transfer to a hospital involved trust in hospitals. This trust was shared by the home health care patients, their relatives and the home health care staff, according to the patients. Conclusions: This thesis revealed that middle-aged and older persons who had been hospitalized exhibited a steeper decline in cognition. Specifically, spatial/fluid, processing speed, and general cognitive abilities were affected. The steeper decline in cognition among those who had been hospitalized remained even after controlling for comorbidities. The most common causes of hospitalization among the older persons living in ordinary housing and in nursing homes were cardiovascular diseases, tumours and falls. Not only health-related factors, such as the number of diseases, number of drugs used, and being assessed as malnourished, but also social factors and marital status were related to the hospitalization risk among the older persons living in ordinary housing and in nursing homes. Some risk factors associated with hospitalization differed not only between the men and women but also among the different age groups. The information provided in this thesis could be applied in care settings by professionals who interact with older persons before they decide to seek hospital care. To meet the needs of an older population, health care systems need to offer the proper health care at the most appropriate level, and they need to increase integration and coordination among health care delivered by different care services.

Adolescents - defined as young people between 10 and 19 years of age1 - are, in general, a relatively healthy segment of the population.2 However, the developmental changes that take place during adolescence may affect their subsequent risk for diseases and for a variety of health-related behaviors. In fact, early onset of preventable health problems (e.g. obesity, malnutrition, STDs) and the engagement in health risk behaviors (e.g., sedentary life style, excessive alcohol consumption, unprotected sex) during adolescence, are likely to put them at greater risk for physical and mental health problems at a later stage in life. Moreover, health related problems and health risk behaviors may disrupt adolescents' physical and cognitive development and therefore may affect their ability to think and act in relation to decisions about their health in the future.1 In summary, health-related behaviors in adolescence, apart from their influence on the continuum of "health-disease", they also have the potential to influence future behaviors. In fact, several studies have shown that past behaviors are good predictors of future behaviors .3,4 Thus, promoting healthy practices during adolescence and taking measures to better protect young people from health risks are essential for the prevention of health problems in adulthood.5 According to the World Health Organization, the main problems affecting young people include mental health problems (such as behavioral disorders, eating disorders, suicide, anxiety or depression), the use of substances (illegal substances, alcohol and tobacco), interpersonal violence, nutrition (a proper nutrition consists of healthy eating habits and physical exercise), unintentional injuries (which are a leading cause of death and disability among young people, with road traffic injuries accounting for about 700 deaths per day), sexual and reproductive health (for example, risky sexual behaviors, early pregnancy and childbirth) and HIV (resulting from sexual transmission and drug injection).5,6 On the other hand, the number of children and youth with chronic health conditions has increased dramatically in the past four decades7 as larger numbers of chronically ill children survive beyond the age of 10.8 Despite the lack of data on adolescents' health making it difficult to determine the prevalence of chronic illnesses in this age group9, it is known that one in ten adolescents suffers from a chronic condition worldwide.10 In fact, national population based studies from Western countries show that 20-30% of teenagers have a chronic illness, defined as one that lasts longer than six months.8 The most prevalent chronic illness among adolescents is asthma and the one with the highest incidence is diabetes mellitus, particularly type II.9 Traditionally, healthcare professionals have been mainly investing in health education activities, through the transmission of knowledge with a view to creating habits, customs and behaviors, and promoting healthy lifestyles. However, empowering people does not only consist of giving them the right information11 , i.e. good information is not enough to cause people to make changes.12 The motivation or desire to change unhealthy behaviors and habits depends on many factors, namely intrinsic motivation, control over personal decisions, self-confidence and perception of effectiveness, personal ambivalence, and individualized assistance.12 Many professionals assume that supplying knowledge is sufficient for behavioral changes; however, even very good advice often fails to generate behavioral change. After all, people continue to engage in unhealthy behaviors despite clearly knowing what they should do and how to change. "What is lacking is the motivation to apply that knowledge".13, p.1233 In fact, behavioral change is a complex phenomenon with multiple determinants that also includes motivational variables. It is associated with ambivalent processes expressed in the dilemma between keeping the current status and moving on to new ways of acting. For example, telling adolescents that if they keep on engaging in a certain behavior, they are increasing the risk of developing a long-term condition such as cardiovascular disease, stroke or diabetes is rarely enough to trigger the desired behavioral change; people are more likely to change when they believe that the change is really effective and that they are able to implement it.12 Therefore, it is essential to provide specific training for "healthcare professionals to master motivational techniques, avoid confrontation with the users, and facilitate behavioral changes".14 In this context, motivating patients to make behavioral changes is also an important nursing task where change in lifestyle is a major element of patients' treatment and preventive interventions.15 One of the nurse's goals is to help improve a patient's health or help them to manage existing health conditions. Once nurses are in a position where they have to focus on accomplishing tasks and telling patients what needs to be accomplished16, the role of the nurse is expanding even more into the use of motivational strategies.17 MI is bringing nurses back to therapeutic communication and moving them closer to successful health promotion and disease management, by promoting behavior change and empowering their patients. As the nursing profession evolves, MI is seen as a challenge and the basis of nurse's interactions with individuals, families and communities.16, 17 In the same way, MI may be taken as an essential tool in the provision of nursing care to adolescents, being itself a workspace with possible therapeutic effects regarding problems, clarification of doubts, and development of skills.18 In fact, MI may be particularly applicable in work with adolescents because of their specific developmental stage. Adolescents attempt to establish their own autonomy and identity while struggling with social interactions and moral issues, which leads to ambivalence.19 Consistent with the developmental challenges during adolescence, "MI explicitly honors autonomy, people's right and irrevocable ability to decide about their own behavior"20 while allowing the person to explore possibilities for change of risky or maladaptive behaviours.19 MI can be defined as a directive, client-centred counselling style for eliciting behavior change by helping clients to explore and resolve ambivalence. It is most centrally defined not by technique but by its spirit as a facilitative style of interpersonal relationship.21 It is a set of strategies and techniques widely used in clinical practice based on the transtheoretical model of change. The Stages of Change model describes five stages of readiness—precontemplation, contemplation, preparation, action, and maintenance—and provides a framework for understanding behavior change.22 The MI has been widely tested and applied in different areas, such as modification of addictive behaviors, interventions with offenders in the context of justice, eating disorders, promotion of therapeutic adherence among chronic patients, promotion of learning in school settings or intervention with adolescents at risk.18,23 In general, clinical practice has been adopting the perspective of motivation as something relatively immutable, i.e., the adolescent is either motivated for change/treatment and, in these conditions, the professional's role is to help him/her, or the adolescent is not motivated and then change/treatment is not feasible. Alternatively the theoretical model underlying the MI technique postulates that the individual's adherence to change/treatment depends on his/her motivation, which can change throughout the therapeutic intervention. As several studies found positive results for effects of MI24-26 and its use by health professionals is encouraged23,27 nurses may play an important role in patients' process of change. As nurses have a crucial role in clinical contexts, they can facilitate the process of ending risk behaviors and/or adopting positive health behaviors through some motivational techniques, namely with adolescents. A considerable number of systematic reviews about MI already exist pointing to some benefits of its use in the treatment of a broad range of behavioral problems and diseases.13,28,29 Some of the current reviews focus on examining the effectiveness of MI for adolescents with diverse health risks/problems 30-32. However, to date there are no reviews that present and assess the evidence for the use of nurse-led MI in adolescents. Therefore, we have little knowledge of what works for whom (which adolescent subpopulation) under what circumstances (in which setting, for what problem) in relation to motivational interviewing by nurses. There is a clear need for scoping or mapping the use of MI by nurses with adolescents to identify evidence gaps and to inform opportunities for future development in nursing practice. On the other hand, information regarding nurse-led implemented and evaluated interventions, techniques and/or strategies used, contexts of application and adolescents subpopulation groups is dispersed in the literature33-36 which impedes the formulation of precise questions about the effectiveness of those interventions conducted by nurses and therefore the realization of a systematic review. In other words, it is known that different kind of motivational interventions have been implemented in different contexts by nurses, however does not exist a map about all the motivational techniques and/or strategies used. Furthermore the literature does not clarify which is the role of nurses at cross professional motivational intervention implemented programs and finally the outcomes and evaluation of interventions are unclear. Thus, the practical implication of this mapping will be clarifying all these aspects. Without this clarification is not possible to proceed to the realization of a systematic review about the effectiveness of the use of motivational interviews by nurses to promote health behaviors in adolescents, in a particular context and/or health risk behavior; or regarding the effectiveness of certain technique and/or strategy of MI. Consequently, there are important questions about the nature of the evidence in this area that need to be answered before formulating a precise question of effectiveness. This scoping review aims to respond to these questions. An initial search of the JBI Database of Systematic Reviews & Implementation Reports, Cochrane Database of Systematic Reviews, , Database of promoting health effectiveness reviews (DoPHER), The Campbell Library, Medline and CINAHL, has revealed that currently there is no Scoping Review (published or in progress) on the subject. In this context, this scoping review will examine and map the published and unpublished research around the use of MI by nurses implemented and evaluated to promote health behaviors in adolescents; to establish its current extent, range and nature and identify its feasibility, outcomes and gaps in the evidence defining research priorities in this field. This scoping review will be informed by the JBI methodology37 that suggests a five stage methodological framework for conducting scoping reviews which includes: identifying the research question, searching for relevant studies, selecting studies, charting data, collating, summarizing and reporting the results.

Background. Duodenal injuries are rare in children and classically present following a fall over the handle bar. Retroperitoneal location of the duodenum may lead to delay in diagnosis, and missed injuries are associated with increased morbidity and mortality. Case report. A 5-year-old child was admitted to the National Trauma Center, in Tirana (Albania), 28 hours after a Motor Vehicle Crash (MVC), complaining of mild abdominal pain. He was febrile (39°C) and had a white blood cells count of 18,000 mm3. On physical exam he had mild tenderness. Plain abdominal X-rays and Focused Abdominal Sonography for Trauma (FAST) were negative for free air or free fluid. The CT scan of the abdomen demonstrated free air and fluid in the retroperitoneal space. At laparatomy, a perforation of the second portion of the duodenum was found. A single layer suture repair of the duodenum with wide drainage was performed. The patient was discharged from the hospital tolerating oral feeding 8 days later. Conclusion. Duodenal injuries in children are rare. Most duodenal hematomas are managed non-operatively. This is a case of MCV with delayed presentation that was treated surgically for perforation successfully.

Benzodiazepines continue to be widely prescribed in primary care for longer than guidelines advise and can cause adverse consequences for those who have long-term prescriptions. The aim of this study was to explore the experience of nonmedical prescribers (NMPs) in relation to their role in improving benzodiazepine prescribing management in primary care. A qualitative study using a thematic analysis framework, in which face-to-face interviews with eight NMPs from the disciplines of nursing and pharmacy were conducted in their areas of practice in 2011 in rural localities in southern Scotland. The NMPs view their qualification as rigorous in its capacity to promote more focused and confident practice, and provide detailed knowledge about medications and the ability to question the appropriateness of medicines. As medication review is an integral part of the role of the NMP they are suited to contribute positively to benzodiazepine prescribing management. Although several obstacles to the successful integration and full utilization of non-medical prescribing currently exist, more training in the recognition of mild-to-moderate mental health problems, psychopharmacology and alternative interventions would allow this role to be assumed with confidence. NMPs may have a useful role to play in benzodiazepine prescribing. NMPs have regular contact with patients in the older age group and those with chronic illnesses, and are in a prime position to utilize opportunistic medication review to improve concordance in this area of prescribing.

Improved strategies are urgently required to control infections with enterohemorrhagic Escherichia coli and enteropathogenic E. coli, two dominant zoonotic enteric pathogens responsible for a wide spectrum of illnesses as well as deaths of human being, with tremendous financial cost worldwide. The present study investigates the capacity of two clay nanoparticles (NPs) with opposite surface charges, namely synthetic layered double hydroxide (LDH) and hectorite (HEC) NPs as adjuvants to promote strong immune responses against the infections. Here both LDH and HEC NPs are showed to be able to carry an appreciable amount of Intimin β (1.1 and 4.4 mg per mg clay nanomaterials, respectively) and significantly facilitate antigen uptake by antigen-presenting cells. Remarkably, these clay NPs induce strong antibody and cell-mediated immune responses, which are much higher than that by the potent adjuvant, QuilA. Furthermore, these strong immune responses are well maintained for at least four months in the mouse model, during which there are no changes in histopathology of the animal organs. Collectively these data demonstrate the suitability of LDH and HEC NPs as useful adjuvants in new-generation vaccine formulations to control various infectious diseases.

The not criminally responsible on account of mental disorder (NCRMD) defence is used when claims can be made that offenders are not responsible for their actions due to symptoms of a mental disorder. Bill C-14, now enacted in Canada, has implemented changes making it more difficult for NCRMD defendants to be released back into the public. This enactment appears to have been primarily due to public perceptions rather than actual knowledge of the defence. Thus it seems important to assess what members of the public actually know about the defence. To assess this, 127 participants completed a survey assessing their knowledge of the illnesses generally involved in the NCRMD defence, crimes committed, and punishments received. On average, only 31.6% of responses were answered within 20% of the factual statistics. Results suggest a general lack of knowledge about the defence and demonstrate why important changes should be based on factual information rather than public opinion.

Este trabalho se propõe estudar a obra do poeta cearense Antonio Gonçalves da Silva, conhecido como Patativa do Assaré. O estudo de tal obra encontra-se alicerçado na crítica literária, sobretudo no conceito de textos histórica e socialmente ancorados elaborado por Antonio Cândido, e na discussão do diálogo entre teologia e literatura, a partir da idéia de reescritura de um texto literário a partir de textos sagrados, de Eli Brandão. Dessa forma objetiva-se localizar, no contexto brasileiro, a partir do diálogo entre teologia e literatura, a plausibilidade de nossa pesquisa, ou seja: ao longo da produção literária de Patativa do Assaré, encontramos questões existenciais provocadoras de diversas aflições percebidas no cotidiano do povo sertanejo, as quais nos remetem a questionamentos e temas de cunho teológico, notados através da obra de um poeta, reveladora não somente da dura realidade do nordestino, mas também da fé e esperança deste em um Deus, visto ao longo da poética de Patativa do Assaré não como fonte de castigo, mas percebido como um Deus sensível aos sofrimentos, mazelas e marginalização dos nordestinos desamparados. Assim, acreditamos na proposta de estudar a poética patativana sob a perspectiva de “um olhar teológico”, a partir do qual se percebe “temas teológicos nordestinos”, elaborados a partir do contato do poeta com o catolicismo do sertão, mas que, na percepção e compreensão de mundo de Patativa assumem novos significados e novas interpretações.

Hepatitis C virus (HCV) is emerging as one of the leading causes of morbidity and mortality in individuals infected with HIV and has overtaken AIDS-defining illnesses as a cause of death in HIV patient populations who have access to highly active antiretroviral therapy. For many years, the clonal analysis was the reference method for investigating viral diversity. In this thesis, a next generation sequencing (NGS) approach was developed using 454 pyrosequencing and Illumina-based technology. A sequencing pipeline was developed using two different NGS approaches, nested PCR, and metagenomics. The pipeline was used to study the viral populations in the sera of HCV-infected patients from a unique cohort of 160 HIV-positive patients with early HCV infection. These pipelines resulted in an improved understanding of HCV quasispecies dynamics, especially regarding studying response to treatment. Low viral diversity at baseline correlated with sustained virological response (SVR) while high viral diversity at baseline was associated with treatment failure. The emergence of new viral strains following treatment failure was most commonly associated with emerging dominance of pre-existing minority variants rather than re-infection. In the new era of direct-acting antivirals, next generation sequencing technologies are the most promising tool for identifying minority variants present in the HCV quasispecies populations at baseline. In this cohort, several mutations conferring resistance were detected in genotype 1a treatment-naïve patients. Further research into the impact of baseline HCV variants on SVR rates should be carried out in this population. A clearer understanding of the properties of viral quasispecies would enable clinicians to make improved treatment choices for their patients.

We present the case of a 33-year-old lady who was diagnosed with disseminated Kaposi’s sarcoma and HIV infection. The patient improved on highly active antiretroviral therapy (HAART), however, nine days into treatment, she became febrile and dyspnoeic and developed tender cervical and axillary lymphadenopathy. Despite treatment for suspected sepsis and immune reconstitution, she died in intensive care. Lymph node biopsies revealed coexistent Castleman’s disease and Kaposi’s sarcoma. Initiation of HAART can be rarely associated with unmasking and rapid progression of Castleman’s disease, a phenomenon called immune reconstitution. Urgent investigation and treatment with agents such as steroids and cytotoxic drugs can be life-saving.

Transhumanism is a philosophy whose essence is to use technology to overcome biological limitations of the man and improve the human condition. This overcoming and improvement are understood as freeing the man from illnesses, ageing processes, and achieving the state of full happiness, permanent, top excitement, as well as replacing many organs (and the entire body at some point) with artificial elements (better than the original ones). Transhumanism calls for maximum development and popularization of technology so that the above-mentioned full overcoming and human improvement could occur as soon as possible. This paper presents basic transhumanism ideas, stress the vision of education created within this philosophy and shows transhumanist projects (Clouds over Sidra, Eyeborg, VEST and BrainGate) that can transform education.

We present the case of a 55-year-old man, with a self-limited febrile condition associated to polyserositis with inconclusive investigation. Bilateral pleural and pericardial effusions resolved. The peritoneal fluid loculated and was compatible with an exudate. The patient remained clinically asymptomatic. Two years later, examination revealed a palpable and painless abdominal mass, which imaging study suggested a cystic lesion. Surgical resection was performed and the histological examination revealed a mesenteric pseudocyst. Mesenteric pseudocysts are rare intra-abdominal cystic masses, mostly benign, without causing specific symptoms. Although imaging tests are useful for their differential diagnosis, the histology is mandatory.

A triagem consiste numa avaliação preliminar do paciente, a qual deverá ser efetuada rapidamente, em cerca de 60 segundos, e pode ser confiada à equipa paramédica. Esta avaliação tem como principal objectivo determinar se o animal apresenta uma ou várias lesões susceptíveis de comprometer as suas funções vitais. Ao longo deste trabalho, são demonstradas diferentes escalas de triagem, de forma a dar a conhecer diversas formas de abordagem ao paciente crítico. Devido ao facto de existirem cada vez mais pacientes a dar entrada nos serviços de urgência veterinária, cria-se a necessidade de tentar adaptar uma destas escalas a esta realidade, tal como acontece em medicina humana. Uma grande variedade de sistemas, que classificam a gravidade das doenças, têm sido usados nos cuidados intensivos em humanos e sistemas similares têm sido desenvolvidos para unidades de cuidados intensivos de pequenos animais. Deste modo, esta dissertação de mestrado, através de um estudo estatístico, procurou correlacionar diferentes variáveis com a sobrevivência de um grupo de animais, em estado crítico, que deu entrada no Centro Hospitalar Veterinário (CHV).

Leptospirosis is an important but neglected zoonotic disease that is often overlooked in Africa. Although comprehensive data on the incidence of human disease are lacking, robust evidence of infection has been demonstrated in people and animals from all regions of the continent. However, to date, there are few examples of direct epidemiological linkages between human disease and animal infection. In East Africa, awareness of the importance of human leptospirosis as a cause of non-malarial febrile illness is growing. In northern Tanzania, acute leptospirosis has been diagnosed in 9% of patients with severe febrile illness compared to only 2% with malaria. However, little is known about the relative importance of different potential animal hosts as sources of human infection in this area. This project was established to investigate the roles of rodents and ruminant livestock, important hosts of Leptospira in other settings, in the epidemiology of leptospirosis in northern Tanzania. A cross-sectional survey of rodents living in and around human settlements was performed alongside an abattoir survey of ruminant livestock. Unusual patterns of animal infection were detected by real-time PCR detection. Renal Leptospira infection was absent from rodents but was detected in cattle from several geographic areas. Infection was demonstrated for the first time in small ruminants sub-Saharan Africa. Two major Leptospira species and a novel Leptospira genotype were detected in livestock. L. borgpetersenii was seen only in cattle but L. kirschneri infection was detected in multiple livestock species (cattle, sheep and goats), suggesting that at least two distinct patterns of Leptospira infection occur in livestock in northern Tanzania. Analysis of samples from acute leptospirosis in febrile human patients could not detect Leptospira DNA by real-time PCR but identified social and behavioural factors that may limit the utility of acute-phase diagnostic tests in this community. Analysis of serological data revealed considerable overlap between serogroups detected in cattle and human leptospirosis cases. Human disease was most commonly attributed to the serogroups Mini and Australis, which were also predominant reactive serogroups in cattle. Collectively, the results of this study led to the hypothesis that livestock are an important reservoir of Leptospira infection for people in northern Tanzania. These results also challenge our understanding of the relationship between Leptospira and common invasive rodent species, which do not appear to maintain infection in this setting. Livestock Leptospira infection has substantial potential to affect the well-being of people in East Africa, through direct transmission of infection or through indirect effects on food production and economic security. Further research is needed to quantify the impact of livestock leptospirosis in Africa and to develop effective interventions for the control of human and animal disease.
