In this context, practical intervention of the social work is of great need and relevance. The research objective was the understanding of the social modifications in the lifestyle of chronic renal disease patients submitted to hemodialysis treatment from the patient's most significative experiences and introspective reflections about the illness and it's treatment. From our experience and the results obtained from the present investigation, some remarkable aspects are: the public health policies contribution aimed to patients with chronic renal disease, such as rights assurance, based on ANVISA's RDC-154 (2004); the knowledge correlated to the social stigma and to the discriminatory process imposed by the illness-related segregation; the importance of the actuation of the Social Services with the chronic renal patients submitted to hemodialysis, through the Professional Mediation. The methodology used was video recorded Focus Groups. The objective was to understand how the chronic renal patients submitted to hemodialysis experience the treatment and the most significative difficulties during the sickening process. Some empirical categories emerged from the process, such as Disease, Family, Kidney Transplant, Health Teams, Multidisciplinary Team. Willing to discuss the profession essence, we evolved a reflexion based on the emerged categories / A doença renal crônica e o tratamento de hemodiálise impõem ao paciente renal crônico, um grande desgaste e uma série de limitações que envolvem o biológico, o social e o psicológico. Neste contexto, a intervenção prática do assistente social se faz presente e necessária. Neste sentido esta pesquisa objetivou compreender as modificações sociais no modo de vida dos pacientes renais crônicos em hemodiálise, a partir da vivência e das inflexões mais significativas que o paciente atribui à doença e seu tratamento. Através da experiência que reunimos nesta área e dos estudos obtidos através da presente investigação, alguns aspectos merecem destaque: a contribuição das políticas públicas de saúde destinadas aos pacientes renais crônicos como garantia de direitos, a partir da RDC-154 de 2004 da ANVISA; os necessários conhecimentos correlatos ao estigma social e ao processo discriminatório da segregação imposta pela doença; a importância da ação do Serviço Social com os pacientes renais crônicos em hemodiálise, através da mediação profissional. A metodologia utilizada foi norteada pela técnica de grupo focal em vídeo, com o objetivo de compreender como os pacientes renais vivenciam a experiência do tratamento e as dificuldades mais significativas no processo do adoecimento. Como resultado deste processo algumas categorias empíricas emergiram, tais como, doença, família, transplante renal, equipes de saúde, equipe multiprofissional. Em torno delas desenvolvemos uma reflexão, procurando remeter ao debate a essência da profissão

The purpose of this study was to examine health literacy and treatment adherence among Latinos with end stage renal disease. Health literacy has been overlooked as one of the factors that affects one's ability to comply with the physician's prescribed medical treatment.

The prevalence of chronic Lyme disease (CLD) remains relatively unknown in Connecticut because there is not an agreement on what CLD is and how it should be diagnosed in addition to which pathological agent causes CLD. The aim of this quantitative study was to assess whether there were significant differences between two groups of primary care physicians (PCP) working in Connecticut from two different points in time regarding their knowledge in the diagnosis, treatment, and management of CLD. A knowledge, attitude, and practice model was used as the underlying theoretical framework for this study. A random cross-sectional survey was mailed out to the 1,726 PCPs found in the list of certified medical doctors in Connecticut of 2015. One hundred and forty-five PCPs responses (11.9% response rate) were received and compared to responses from previous data (a 2010 study) of 285 PCPs (39.1% response rate) from the list of certified medical doctors in 2006. The PCP estimated mean number of patients diagnosed and treated for CLD was not significantly different between 2006 and 2015. However, a significantly higher number of PCPs in 2015 reported knowing Lyme disease (LD) symptoms but not feeling comfortable diagnosing LD (χ� = 536.83, p < 0.001), and significantly more PCPs in 2015 reported knowing LD symptoms and feeling comfortable diagnosing CLD (χ� = 265.41, p < 0.001). This study can promote social change by encouraging Connecticut PCPs to recognize CLD as a diagnosis to enable the development of registries and case-control assessments. The findings of this study may also inspire future studies.

The overall aim of this thesis was to describe subjects with chronic obstructive pulmonary disease (COPD) from different perspectives. Focus was on patients at the time of diagnosis, impact of the disease in comparison to other chronic diseases, factors associated with good health and quality of life (QoL), and diagnostic spirometry in clinical practice. Methods: Qualitative method, grounded theory, was used to analyse patients´ perspectives at the time of diagnosis in a primary care setting (n=10). Public health surveys in the general population were used to compare chronic diseases (n=10,755) and analyse factors associated with health outcomes in COPD (n=1,475). Medical records and spirometry reports, from primary and secondary care, were analysed to assess diagnosis of COPD in clinical practice (n=533). Results: In clinical practice, 70% of patients at the time of diagnosis of COPD lacked spirometry results confirming the diagnosis. Factors related to consequences of smoking, shame and restrictions in physical activity (PA) in particular, were described by patients at the time of diagnosis of COPD. In general subjects with COPD (84%), rheumatoid arthritis (74%) and diabetes mellitus (72%) had an activity level considered too low to maintain good health. In COPD, the most important factor associated with good health and quality of life was a high level of PA. Odds ratios (OR (95%CI)) varied from 1.90 (1.47-2.44) to 7.57 (4.57-12.55) depending on the degree of PA, where subjects with the highest PA level had the best health and QoL. Conclusions: Subjects with COPD need to be diagnosed at an early stage, and health professionals should be aware that feelings of shame could delay patients from seeking care and thus obtaining a diagnosis. The use of spirometry and the diagnostic quality should be emphasised. In patients with COPD greater attention should be directed on increasing the physical activity level, as patients with a low level of physical activity display worse health and quality of life.

The aim of this thesis was to elucidate the role of carbonic anhydrase (CA) in the modulation of central pH/CO2-sensitive fictive breathing (measured using in vitro brainstem-spinal cord preparations) in leopard frogs (Rana pipiens) following exposure to chronic hypercapnia (CHC) and chronic hypoxia (CH). CHC caused an augmentation in fictive breathing compared to the controls (normoxic normocapnic). Addition of acetazolamide (ACTZ), a cell-permeant CA inhibitor, to the superfusate reduced fictive breathing in the controls and abolished the CHC-induced augmentation of fictive breathing. ACTZ had no effect on preparations taken from frogs exposed to CH. Addition of bovine CA to the superfusate did not alter fictive breathing in any group, suggesting that the effects of ACTZ were due to inhibition of intracellular CA. Taken together, these results indicate that CA is involved in central pH/CO2 chemoreception and the CHC-induced increase in fictive breathing in the leopard frog.

This study looked into paients’ experiences of end stage renal disease (ESRD) and renal replacement therapy (RRT). A qualitative me thodology was employed involving fifteen patients between the ages of 20 – 60 years that were interviewed on their experiences using the semi structured approach to interviewing. The knowledge gained was analysed thematically. The study was explored within two theoretical frameworks, namely the biopsychosocial and the ecological models. Results of the study revealed that ESRD and RRT posed many psychosocial challenges at a micro and macro level, as patients attempted to reconcil e these experiences with their lifestyles and lives. Challenges were expressed in the areas of functional capacity, work and sexuality. Family life was seriously affected when patients had to make themselves available for life long tr eatment that depended on machines. Recommendations included mobilisatio n of positive support networks, religion/spirituality, and pr ofessional support playing an interrelational role in enabling patients to cope through the long term process so that they may emerge from it with a modicum of quality in their life. Thus a team approach was key to optimal living for the patient. From an ecological perspective, macrosystemic change was also considered important for government to introduce policies that ensure economically productive living for persons with kidney dysfunction. / Thesis (M.A.)-University of KwaZulu-Natal, Durban, 2008.

[Truncated abstract] Despite significant scientific advances in tracking the complex physiological mechanisms that drive the asthma disease process, worldwide trends in childhood asthma continue to rise. This research sought to describe the relationships between psychosocial stress, psychosocial resources, asthma severity, and health-related outcomes from the standpoints of biopsychosocial and developmental theory. The research consisted of three studies based on a prospective study involving 2573 children from a community-based birth cohort. The cohort has been under active follow-up from birth and this thesis draws on data obtained at the 1, 2, 6, 10 and 13 year follow-ups . . . The final study undertook to describe the mediating influence of specific supportive behaviours provided by family members and peers to adolescents with asthma. Ninety-nine adolescents participating in the 13 year follow-up of the community cohort study completed a semi-structured interview adapted from the Diabetes Social Support Interview (La Greca et al., 1995) to assess supportive behaviours and the KINDL (Ravens-Sieberer & Bullinger, 1998) to assess QOL. It was predicted that illness-specific support would mediate the relationship between family dysfunction and quality of life. Qualitative analyses identified parents as important sources of tangible support, peers as important sources of companionship and emotional support, and siblings bridging the two, by providing tangible, companionship and emotional support to the adolescent. Mediator analyses found that specific parent behaviours perceived as unsupportive by the adolescent mediated the relationship between family dysfunction and self-oriented quality of life. Clinical implications support the integration of medical and psychological expertise in the treatment of asthma. Future research directions are also discussed.
