Bakgrund: Prostatacancer är en sjukdom som påverkar ett stort antal män världen över där behandlingsalternativen ofta följer med svåra biverkningar för patienten. Biverkningarna påverkar bland annat sexuell hälsa och urinvägar. Biverkningarna påverkar även männens identitet och manlighet.  Syfte: Syftet med litteraturöversikten var att beskriva patienters upplevelser av prostatacancer. Metod: En litteraturöversikt användes där författarna hittade 10 stycken kvalitativa vetenskapliga artiklar som sammanställts till resultatet i denna studie.  Resultat: Resultatet visar att männens upplevelser kring prostatacancer är ofta svåra för männen och att det finns många påverkande faktorer mot deras identitet och självkänsla.  Sammanfattning: Med denna studie ger vi en ökad förståelse för männens upplevelser under sin sjukdom med prostatacancer och ge kunskap till sjuksköterskor om männens psykiska tillstånd för att kunna utföra god omvårdnad. / Background: Prostate cancer is a disease that affects many men around the world where treatment options often come with severe side effects for the patient. The side effects affect their sexuality among other things, but there are many more serious side effects. The side effects also often hit hard on men's identity, which often has serious consequences on their life.  Aim: The aim of this literature overview was to describe patient’s experiences of prostate cancer.  Method: A literature review was performed where 10 articles was found for our result.  Results: The results showed that men's experiences of prostate cancer are often difficult for men and that there are many influencing factors towards their identity and self-esteem.  Conclusion: With this study we provided an increased understanding of men's experiences during their illness with prostate cancer and to provide nurses with knowledge about men's mental state in order to be able to perform good nursing.

Bakgrund: När individer diagnostiseras med ADHD är det inte ovanligt att individen påbörjar en centralstimulerande läkemedelsbehandling. Men forskningen kring läkemedelsbehandlingens påverkan på sexualiteten är skral både nationellt och internationellt. Det finns ett behov av att få bättre förståelse de konsekvenser som centralstimulerande läkemedelsbehandling kan ha för individers sexuella hälsa och välbefinnande. Syfte: För att fördjupa kunskapen inom detta område syftade denna studie att undersöka hur vuxna personer med ADHD upplever att centralstimulerande läkemedelsbehandling påverkar deras sexuella hälsa och välbefinnande samt vilka upplevelser de har av hälso- och sjukvårdens bemötande i relation till frågor som rör sexualitet och ADHD-läkemedel.Metod: Studien utgår ifrån en kvalitativ forskningsdesign bestående av nio semistrukturerade intervjuer. Empirin har analyserats utifrån en reflexiv tematisk analys.Resultat: Resultatdelen bygger på tre huvudteman: Medicinska biverkningars påverkan på sexualitet, Intervjupersoners upplevelser av sitt medicinerande sexuella jag – individuellt och relationellt och Sexualitet i en vårdkontext. Dessa har analyserats med hjälp av begreppen compulsory sexuality och compulsory able-bodiedness för att förstå hur normer kring sexualitet och kroppslig funktion samverkar och påverkar individers upplevelse av sin sexualitet. Slutsats: Resultaten visar att centralstimulerande läkemedel påverkar sexualiteten både positivt och negativt i relation till kroppsliga, psykologiska och sociala faktorer. I studien uppkommer även behov och önskemål om att sexologiska frågeställningar och information om sexuella biverkningar lyfts i hälso- och sjukvården. Resultaten är av vikt för den kliniska sexologin för att ämnet ska synliggöras och uppmärksammas i praktiken för att möjliggöra sexuellt välbefinnande hos vuxna personer med ADHD. / Background: When individuals are diagnosed with ADHD it is not uncommon that they begin a treatment with stimulant medication. However, research about the impact of said treatment is sparse, both nationally as well as internationally. There lies a need to make better understanding of what consequences central stimulants can have for the individual's sexual health and well-being. Aim: To deepen the knowledge within this field, the study aims to examine how adults diagnosed with ADHD experience how being treated with central stimulants affects their sexual health and well-being, as well as what experiences these individuals have regarding how they are being approached by health care professionals with reference to questions about sexuality and medication for ADHD. Method: A qualitative research method has been used in this study, consisting of nine semi-structured interviews. The observations have been analyzed with a reflexive thematic analysis.Results: The results are divided into three major themes: The influence that medical side effects have on sexuality, How the interviewees view their medicating sexual self - individually and with others and Sexuality in a health care context. The themes have been analyzed together with the concepts of compulsory sexuality and compulsory able-bodiedness in order to understand how social norms regarding sexuality and bodily function intertwine with - and affect – individuals’ view on their own sexuality. Conclusion: The results show that central stimulants affect sexuality in both positive and negative ways regarding bodily, psychological and social factors. The study also shows that there is a need for questions of sexological matter to be brought up by health care professionals, as well as giving information about potential side effects that have an impact on sexual health. The results are important for the clinical sexology field and practition, in order to raise awareness for this subject and to enable sexual well-being for adults with ADHD.

The use of methylenedioxymethamphetamine (MDMA) or Ecstasy is a phenomenon that has established itself in the widespread Rave culture. Ecstasy use causes not only physical, social and psychological problems in the development of the adolescent but may also influence his concentration and learning abilities. To prevent these problems educators should be well informed regarding current drug use trends and also be capable of assisting adolescents. Research regarding the nature of Ecstasy use and the characteristics of its users is lacking nationally. The increase in use amongst school going adolescents and young adults and the fact that there are side effects and unknown long term effects has made it imperative that educators learn as much as possible about this drug. The purpose of this research is therefore to furnish the educator with accurate information that will enable him to obtain a reference point from which assistance can be offered to the young Ecstasy user. / Psychology of Education / M.Ed.(Guidance and Counselling)

Chemical substance abuse and dependence constitute an increasing international and national phenomenon. Individuals, groups and communities are at risk of the mental, biological, legal and environmental implications associated with substance dependence. Human sexual behaviour is no new phenomenon to be studied. Human beings experience sexual behaviour and gratification as important. Sexual behaviour is not vital for the survival of the individual but vital for survival of the species. Sexual behaviour in combination with chemical substance abuse might pose further dangers to a person or group. Sexual behaviour where persons engage in sexual actions when using or abusing chemical substances could construct certain positive functions for persons. Qualitative researchers are interested in discovering the meaning persons attach to experiences. In understanding the dynamics of the phenomenon, possible contributions to the human sciences could be made. Chemical substance abuse and dependency affect the individual, his/her family systems and the community. Depressants and stimulants change the chemical functioning of the human brain and the mental health of the user. Despite the harm caused to the dependent person, abuse of the chemical substance is continued. The substance has various functions that the biological and psychological person becomes dependent on. Sexual behaviour is inherent in human nature, but not chemical substance abuse. It is expected by the researcher that there might be certain function(s) served by chemical substances in the sexual behaviour of persons. A literature study on the topic on the function of chemical substances in the sexual behaviour of persons yielded unsatisfactory results. Little research was found with regard to the function of chemical substances in relation to people’s sexual behaviour. In response to this need the researcher embarked on a qualitative research journey to explore the function of the chemical substances within the context of an individual’s sexual behaviour and practices. Chemical substances have different functions and affect the sexual behaviour, functioning and experiences of the users of such substances. Six objectives were set with the aim of developing an in-depth understanding of the function of chemical substances in sexual behaviour. The research question of this investigation leads to a clear inquiry into the phenomenon that was examined and analysed and yielded useful new information. This qualitative research project is characterised by its inductive features, openness to change and interest in human behaviour. The study is characterised by an interpretive nature as an interpretative investigation. An effort was made towards understanding the phenomenon through observation and exploration. Persons were invited to participate in the research and reported themselves to the researcher, the process of self-selection sampling was utilised. In drawing a sample from the population of patients at a treatment centre an interactive approach to the process was followed by conducting semi-structured and in-depth interviews as a method of data collection. Data analysis and processing was executed according to the eight steps for qualitative data analysis as proposed by Tesch (in Creswell, 2009). Data verification for the assessment of the trustworthiness of the research findings was achieved by utilizing Guba’s model as espoused in Krefting (1991). Informed consent, confidentiality and management of information were some of the ethical considerations adhered to in the planning and execution of this research project. The nature of this study is marked by the person-centred approach in combination with the qualitative methodology and philosophy. The researcher found the two to be appropriate when a sensitive and private topic was to be explored. Participants were able to evaluate the meanings that were attached to their experiences within a psychologically sound environment. Themes became evident through the data analysis process. These themes were contrasted against a body of existing theory. The wholeness of human beings came to the fore and literature from a bio-neurological and humanistic perspective was found to be applicable. The social sciences and, in particular, social workers are concerned with the wellbeing of persons, their relevant systems and context. These dimensions of human beings were addressed by this study and aimed to contribute to further development in the science of psychotherapy and the understanding of the person within the phenomenon being studied. Therapists should be willing and demonstrate a sensitive ability to understand the client’s experiences from the person’s own point of view (Rogers, 1950: 444). In a relationship that is constructed for the purpose the aim should be mainly to understand the whole person (Rogers, 1952: 343). Therapists should develop an ability to see completely through the client’s eyes and adopt the person’s frame of reference. This is the basis for implementing “client-centred” therapy (Rogers 1950: 444). A key role of social work practice is facilitating the empowerment of persons, and their personal and interpersonal strengths according to their own self-determination (Zastrow, 2012:39); the researcher recommends a holistic full understanding of the person in his/her wholeness (Rogers, 1987: 486). / Exploring the functions of chemical substances in individuals' sexual behavior / Interviews in English and Afrikaans / Department of Social Work / M.A. (Social Work)

The thesis deals with possibilities of an application of system dynamics methodics for an understanding and teaching the project management. A dynamic simulation model has been created for this purpose by using Vensim. A web simulator for the project management, which is based on the simulation model, has been created in the next part of the thesis. The benefit of the simulator over the model is its user- friendliness and its self-explanatory graphic interface, which makes it possible to use the simulation model for purposes of teaching and further reaserch in the field of project management.

Introdução: Tenofovir disoproxil fumarate (TDF) é um inibidor da transcriptase reversa análogo nucleotídeo que tem sido usado por gestantes para o tratamento da infecção pelo vírus da imunodeficiência humana (HIV), bem como para a prevenção da transmissão vertical do vírus. Até o momento, não há estudos experimentais ou em humanos sobre a incidência de alterações renais nos fetos expostos a esquemas contendo TDF. Objetivo: Verificar a ocorrência de alterações renais e sistêmicas fetais causadas pelo uso do TDF durante a gestação. Metodologia: Ratos Wistar fêmeas receberam dieta padrão com ou sem adição de TDF (100mg/Kg de dieta) desde uma semana antes do cruzamento até o parto. A prole proveniente do grupo TDF foi colocada com uma mãe adotiva não tratada durante o período de amamentação e foi comparada com a prole de ratas que receberam dieta padrão durante a gestação (grupo controle). Controle e TDF foram acompanhados até três (n=9 para cada grupo) e seis (n=12 e n=10, respectivamente) meses de idade. Foram avaliados: peso corporal (PC) e pressão arterial sistólica (PAS) mensais, contagem de glomérulos, função renal (através do clearance de inulina), parâmetros bioquímicos (proteinúria, colesterol total, sódio e potássio séricos e urinários), e expressão proteica do tecido renal para componentes do sistema renina angiotensina aldosterona (SRAA) e para transportadores de sódio. Resultados: A prole TDF apresentou menor PC ao nascimento em comparação com o controle. Após o 3º mês, o grupo TDF demonstrou um crescimento compensatório, atingindo o sexto mês com maior PC. O peso renal foi menor no grupo TDF, porém, não houve diferença do número de néfrons entre os grupos. O grupo TDF apresentou alterações estruturais glomerulares. Observou-se também um aumento progressivo da PAS após o segundo mês de idade no grupo TDF. Não houve diferença estatística na função renal entre os grupos. Os níveis plasmáticos de aldosterona foram mais elevados no grupo TDF, em associação com um aumento da expressão renal do SRAA. Ratos do grupo TDF apresentaram menor excreção renal de sódio e maior expressão renal de transportadores de sódio. Conclusões: Esta é a primeira descrição, a partir de um modelo experimental, que a utilização do TDF durante a gestação resulta em hiperativação do SRAA, aumento da expressão dos transportadores renais de sódio e hipertensão arterial da prole / Introduction: Tenofovir disoproxil fumarato (TDF) is a nucleotide reverse transcriptase inhibitor that has been used in pregnants for treatment of maternal HIV infection and for prevention of vertical transmission. Currently, there are no published studies providing data regarding the occurrence of renal abnormalities in fetuses exposed to TDF-containing regimens. Objective: To evaluate the occurrence of systemic and renal abnormalities in offspring of Wistar rats exposed to TDF during pregnancy. Methods: Female Wistar rats received a standard diet, with or without addition of TDF (100 mg/Kg diet), one week before mating and during pregnancy. Offspring from the TDF group were placed with an untreated foster mother during breastfeeding and compared with offspring from rats maintained on a standard diet during mating and pregnancy (control). Control and TDF were followed up at three and six months of age. Analyzed data: monthly body weight and systolic blood pressure (SBP), glomerular counting, renal function, biochemical parameters, and renal tissue immunoblotting for renin angiotensin aldosterone system (RAAS) and renal sodium transporters. Results: TDF offspring showed lower birth weight compared with the control group. After the third month, growth among the TDF group experienced a rapid catch-up. SBP increased progressively after the second month of age in the TDF group. The nephron number did not differ between groups. The TDF group showed glomerular structural changes. There was no significant difference in renal function between the groups studied. Plasma aldosterone was higher in the TDF group, associated with a significant increase in renal expression of RAAS. The TDF rats showed upregulation of renal sodium transporters and consequently lower urinary sodium excretion. Conclusions: This is the first demonstration using an experimental model that maternal exposure to TDF during gestation results in over activation of RAAS, upregulation of renal sodium transporters and hypertension of the offspring

A Síndrome da Imunodeficiência Adquirida (AIDS) é um problema de saúde pública. O Tenofovir Disoproxil Fumarato (TDF) foi o primeiro inibidor do nucleotídeo da transcriptase reversa e é a droga mais recomendada para o tratamento da AIDS. Entretanto, o uso prolongado de TDF está associado com a nefrotoxicidade. A deficiência de vitamina D tem alta prevalência em indivíduos infectados com o Vírus da Imunodeficiência Humana (HIV). A vitamina D participa da regulação de atividades fisiológicas de diversos órgãos, incluindo o rim, oferecendo proteção contra as lesões ocasionadas por diferentes causas. Portanto, pacientes com níveis baixos de vitamina D infectados com o HIV podem apresentar complicações renais e cardiovasculares durante a terapia antirretroviral. Sendo assim, a carência desta vitamina pode acelerar a progressão da doença renal. Tendo em vista o aumento da incidência de hipovitaminose D na população mundial, esse trabalho tem o objetivo de verificar os mecanismos que levam ao desenvolvimento da lesão renal em ratos depletados de vitamina D submetidos ao tratamento com TDF. Ratos Wistar foram divididos em quatro grupos: controle, animais que receberam dieta padrão por 60 dias; dVD, animais que receberam dieta depletada em vitamina D por 60 dias; TDF, animais que receberam dieta padrão por 60 dias com a adição de TDF (50 mg/kg de dieta) nos últimos 30 dias; e dVD+TDF, animais que receberam dieta depletada em vitamina D por 60 dias com a adição de TDF nos últimos 30 dias. Ao final dos 60 dias, os animais foram submetidos à eutanásia, amostras de sangue, urina e o tecido renal foram coletados para a análise dos mecanismos de lesão renal. O tratamento com TDF levou a insuficiência renal observada pela queda da filtração glomerular e lesão tubular proximal com aparecimento de fosfatúria ocasionada pela diminuição do cotransportador sódio/fosfato subtipo IIa. Essas alterações foram acompanhadas de hipertensão e modificações no perfil lipídico. A deficiência em vitamina D associada à administração de TDF agravou os efeitos renovasculares e a nefrotoxicidade induzida pelo TDF, pelo menos em parte, devido ao aumento nos marcadores de estresse oxidativo e a participação do sistema renina-angiotensina-aldosterona. Portanto, é essencial monitorar os níveis de vitamina D em pacientes infectados com o HIV tratados com TDF / Acquired Immunodeficiency Syndrome (AIDS) has become one of the world\'s most serious health problem. Tenofovir Disoproxil Fumarate (TDF) was the first available nucleotidic reverse transcription inhibitor and is a widely prescribed antiretroviral medication for treatment of Human Immunodeficiency Virus (HIV). However, the long-term use of TDF has been associated with a number of toxicities, including those affecting the kidney. Vitamin D deficiency is prevalent among HIVinfected individuals. Vitamin D not only regulates numerous physiological activities of multiple organ systems, but also protects the kidney from injury from different causes. Thus, HIV-infected subjects with low levels of vitamin D could experience increased complications during antiretroviral therapy, such as cardiovascular disease and renal impairment. In view of the high worldwide incidence of hypovitaminosis D, the aim of this study was to investigate the effects of vitamin D deficiency on TDF-induced nephrotoxicity. Wistar rats were divided into four groups: control, receiving a standard diet for 60 days; dVD, receiving a vitamin D-free diet for 60 days; TDF, receiving a standard diet for 60 days with the addition of TDF (50 mg/kg food) for the last 30 days; and dVD+TDF receiving a vitamin D-free diet for 60 days with the addition of TDF for the last 30 days. At the end of the protocol, animals were euthanized and blood, urine and tissue samples were collected in order to evaluate the mechanisms responsible for renal injury. TDF led to impaired renal function, hyperphosphaturia, hypophosphatemia, hypertension and increased renal vascular resistance due to downregulation of the sodium-phosphorus cotransporter and upregulation of reninangiotensin- aldosterone system (RAAS). TDF also increased oxidative stress, as evidenced by higher TBARS and lower GSH levels, and induced dyslipidemia. Association of TDF and vitamin D deficiency aggravated renovascular effects and TDFinduced nephrotoxicity at least in part by the increase of oxidative stress and the involvement of RAAS. Hence, it is important to monitor vitamin D levels in HIV-infected patients treated with TDF
