Efeito nas mudanças temporárias dos limiares auditivos durante o uso de próteses auditivas de alta potência / Effect in the temporary threshold shift during the use of the high power hearing aid

Ursula Maria Lellis de Vitto 17 February 2005 (has links)
Alterações temporárias ou permanentes na audição podem ser encontradas nas orelhas submetidas a níveis elevados de pressão sonora. As mudanças temporárias induzidas nas orelhas protetizadas, quando estimuladas por suas próteses auditivas ajustadas na amplificação prescrita, foram avaliadas em um grupo de 25 pacientes após um período controlado (2 a 2 ½ h) de exposição ao ruído presente em um ambiente acústico comum. O estudo foi dividido em três etapas. Uma medida inicial foi realizada na primeira etapa para mensurar a magnitude das mudanças temporárias dos limiares auditivos, induzidas nas 42 orelhas (25 pacientes) durante um período contínuo de exposição ao ruído, com suas próteses auditivas ajustadas na amplificação prescrita. Na segunda etapa, essas 42 orelhas foram divididas em dois grupos distintos: as 22 orelhas protetizadas (13 pacientes) que apresentaram maior mudança temporária inicial nos limiares auditivos foram incluídas no Grupo Experimental e as 20 orelhas protetizadas (12 pacientes) que apresentaram menor mudança temporária inicial nos limiares auditivos foram incluídas no Grupo Convencional. Nesta etapa, as próteses auditivas, adaptadas nas 22 orelhas incluídas no Grupo Experimental, tiveram a sua amplificação reduzida por um período de 60 a 90 dias proposto para o \"treinamento\" das orelhas no uso cotidiano de suas próteses auditivas. Após este período de treino, a amplificação das próteses auditivas retornou ao nível prescrito. No Grupo Convencional, a amplificação prescrita das próteses auditivas adaptadas não foi alterada. Durante esta etapa, quatro medidas das mudanças temporárias induzidas nos limiares auditivos foram realizadas para os dois grupos nas mesmas condições de exposição ao ruído adotadas para a determinação da medida inicial. Uma última medida das mudanças temporárias induzidas nos limiares auditivos foi realizada na terceira etapa, também em idênticas condições. Esta última medida ocorreu em média 30/35 dias depois do término do treinamento, quando os pacientes do Grupo Experimental já faziam o uso cotidiano de suas próteses auditivas reajustadas na amplificação prescrita. A análise estatística de variância (ANOVA) comparou o comportamento das mudanças temporárias induzidas nos limiares auditivos nas três etapas do estudo. Para as orelhas incluídas no Grupo Experimental, foram verificadas alterações estatisticamente significantes (f<0,05) durante as etapas do estudo. As mudanças temporárias induzidas nos limiares auditivos das orelhas incluídas no Grupo Experimental aumentaram nos primeiros quinze a trinta e cinco dias após o inicio do treinamento. Com a continuidade do treinamento essas alterações foram gradualmente se reduzindo. As mudanças temporárias induzidas no final do treinamento (etapa pós-experimental) foram as menores observadas durante o estudo. A redução teve inicio nas freqüências abaixo de 1000 Hz e se extendeu na faixa de freqüência mais afetada nas orelhas protetizadas durante a exposição inicial ao ruído ambiente (250 a 2000 Hz). Para as orelhas incluídas no Grupo Convencional não foram constatadas alterações estatisticamente significantes (f>0,05) nas mudanças temporárias induzidas nos limiares auditivos quando avaliadas nas mesmas condições de exposição ao ruído ambiente. Entretanto, para as freqüências mais graves (250 Hz), foi verificada uma tendência a redução nestas alterações no decorrer do estudo / It is well known that the temporary threshold shift in hearing sensitivity is the most obvious hearing effect of the high level acoustic stimulation. Temporary threshold shifts induced in the aided ears were measured in 25 patients after the use of the hearing aids fitted in the prescribed gain during a controlled exposition time (2 a 2 ½ h) to an environmental noise. The study was performed in three phases. In the first phase a first measure of the temporary threshold shift was obtained for 42 aided ears (25 patients) in order to measure the initial amount of temporary threshold shift induced by the hearing aids fitted in the prescribed acoustic gain. In the second phase the ears were included into two study groups: The Experimental Group (EG) formed by 22 ears (13 patients) with greater temporary threshold shift in the initial measure and the Conventional Group(CG) , formed by 20 ears with the shorter temporary threshold shift in the initial measure . The hearing aids amplification in the 22 aided ears of the Experimental Group was reduced during the daily use for a \"training\" period of about 60 to 90 days, and after that was turned to the prescribed gain. The prescribed gain was not modified to the 20 ears of the Conventional Group. Four measure of temporary threshold shift were performed in the second phase when the patients included in the two groups were exposed to an environmental noise in the same conditions used to obtain the initial measure. The last measure (post-experimental phase) of the temporary threshold shift was performed in the same conditions , 30 days in average after the patients of Experimental Group had returned to use their hearing aids in the prescribed gain. In the Experimental Group, the analysis of the variance (ANOVA) showed significant differences(f<0,05) in the amount of induced temporary threshold shifts measured during the three phases of the study. Fifteen or thirteen five days after the training had begun the amount of temporary threshold shift increase, but with the continuous training it was gradually to reduced .In the end of the study, the last measure (post-experimental phase) was performed and the amount of temporary thresholds shift was very shorter. This reduction of temporary threshold shift was initially verified in the frequencies below 1000 Hz and at the end of the study all of the frequencies initially affected during the exposition time to the environmental noise (250 to 2000 Hz) were significantly reduced. In the ears included in the Conventional Group it was not verified temporary threshold shift statistically significant (f>0,05) in any moment, but in the low frequencies (250 Hz) it was noticed a gradually reduction of the amount of temporary threshold shift during the period of this study

Violência de Gênero, Necessidades de Saúde e Uso de Serviços em Atenção Primária. / Gender violence, Healthcare needs and the use of healthcare services

Ana Flávia Pires Lucas D'Oliveira 21 August 2000 (has links)
Estudou-se a forma usual como a violência vem se apresentando e é ou não trabalhada no interior dos serviços de saúde de atenção primária. A partir da interação que se estabelece entre as usuárias e profissionais desses serviços busca-se as condições que propiciam ou obstaculizam a emergência, o acolhimento e a proposta de intervenção sobre a questão no interior de um serviço de saúde. Foi estudado um serviço específico que tinha como característica ter o PAISM implantado através de observação direta de atividades assistenciais, análise do registro em prontuário e do perfil de consumo do serviço e entrevistas com usuárias e profissionais. Encontrou-se a emergência de conflitos em torno das relações de gênero e violência de gênero no registro tanto em prontuários como na observação direta. Observou-se que as possibilidades de emergência destes conflitos estão ligadas aos canais de comunicação abertos e à possibilidade de antever alguma resposta para o exercício profissional. Discute-se os riscos trazidos pela possível medicalização e psiquiatrização da violência e a importância de um trabalho intersetorial e multidisciplinar para apreender e trabalhar o problema. / The purpose of this paper is to identify the usual ways in which violence has been manifesting itself and how health services deal with it –- or fail to do so. It tries to understand the relation that is established between female users and the professionals who work at these healthcare services with regard to the problem of violence against women as a form of demand capable of generating the production of healthcare. This comprehension has made it possible to understand the conditions that either enable or stand it the way of the manifestation, the provision of care and the intervention proposal relative to the issue within healthcare services. The risks that result from the possible medicalization of violence are also discussed, as well as the importance of interdisciplinary and intersectorial work in both understanding and dealing with the problem.

Efeitos da acupuntura sobre os pacientes com asma leve e moderada persistentes: um estudo randomizado, controlado e cruzado / Effects of acupuncture on patients with mild to moderate persistent asthma: a randomized, controlled, crossover

Hong Jin Pai 11 March 2014 (has links)
Introdução: Este estudo foi realizado com o intuito de avaliar efeitos da acupuntura sobre os pacientes com asma leve e moderada persistentes com o uso de beta-2 agonista ou corticoide inalatório. Métodos e casuística: Trata-se de um estudo prospectivo, duplo-cego, randomizado e cruzado com dois braços. Os 74 pacientes com diagnóstico de asma leve/moderada, de acordo com a classificação de GINA 2002/2003, foram divididos em dois grupos, sendo 31 do Grupo I, e 43 do Grupo II inicialmente. Foram realizadas consultas médicas e exames que incluíram espirometria, citologia de escarro induzido, NO expirado, preenchimento de escala de sintoma, questionários de qualidade de vida de asma e de SF 36, e realização de peak-flow, dependendo da Fase do protocolo. A Fase I constituiu-se dos exames pré-intervenção. Na Fase II, foram realizadas 10 sessões de Acupuntura Real no Grupo I e 10 sessões de Acupuntura Sham no Grupo II, na Fase III, houve 4 semana de washout, na Fase IV, houve a troca de técnicas de acupuntura, sendo uma sessão por semana e, na Fase V, realização dos exames. Resultados: Não há diferença nos critérios de avaliação no pré-tratamento entre dois grupos, com exceção de maior celularidade inflamatória no Grupo II. No entanto, houve uma redução significativa de eosinófilos (p = 0,035) e neutrófilos (p = 0,047), e aumento de macrófagos (p = 0,001), melhora da medida de volume do peak-flow (p = 0,01) na fase IV do Grupo II. No Grupo I, na avaliação de escala de sintomas diária, havia menor uso de medicação de resgate (p = 0,043) na Fase II, e, depois de receber a Acupuntura Sham na Fase IV, havia menos tosse (p = 0,007), menos chiado (p = 0,037), menos dispneia (p < 0,001) e menor uso de medicação de resgate (p < 0,001). No Grupo II, após receber o tratamento com a Acupuntura Sham na Fase II, houve diminuição de tosse (p = 0,037), de chiado (p = 0,013) e de dispneia (p = 0,014), e, na Fase IV, havia menos tosse (p = 0,040), sibilos (p = 0,012), dispneia (p < 0,001) e menos despertares noturnos (p = 0,009). Nos questionários de qualidade de vida de asma e de SF 36, foram encontrados alguns aspectos de melhora significantes na Acupuntura Sham dos dois grupos em relação à Fase I, mas os resultados da Acupuntura Real tiveram maiores índices de melhora em relação aos resultados da Acupuntura Sham nos dois grupos. Mas não há diferença significativa entre os dois na qualidade de vida de SF 36. Entretanto, não houve alteração de avaliação de espirometria e de óxido nítrico expirado. Conclusão: Este estudo demonstrou que o uso de Acupuntura Real num grupo de pacientes com a celularidade mais inflamatória teve melhor resultados de sintomas diários, tais como dispneia e despertar noturno, de medida de volume de peak-flow matutina, e de avaliação de qualidade de vida em asma e SF36, além da diminuição quantitativa de neutrófilos e de eosinófilos, com aumento de macrófagos, que justificam os efeitos anti-inflamatórios e imunitários. A acupuntura é uma terapia segura, não havendo nenhum efeito colateral observado neste projeto que possa interferir com a vida cotidiana e pode ser de grande auxílio no alívio de sintomas, com melhora de qualidade de vida e, possivelmente, pode ter uma ação na modulação do processo inflamatório de vias aéreas / Introduction: This survey has been conducted in order to evaluate the effects of acupuncture in patients with persistent mild and moderate asthma (according to GINA criteria 2003), using beta agonist and/or inhaled glucocorticoid. Methods and patients: This is a prospective, double blinded, randomized and cross-over study with two branches: 74 patients diagnosed with mild and moderate asthma were divided into two groups: Group I with 31, initiating with real acupuncture and Group II, starting with sham acupuncture. Medical interview and laboratory tests including spirometry, induced sputum citology, exhaled NO measurement, quality of life questionnaire (SF-36 and QQL), besides, daily symptom scores and measurement of peak-flow were performed, in the beginning of the study, and in the end of each phase of treatment. Phase I: laboratory tests and other qualitative measurements. There were 10 real acupuncture weekly sessions to Group I and 10 sham acupuncture sessions to Group II in Phase II. On the other hand, in the Phase IV, there was an exchange between Group I and Group II, which was receiving real acupuncture started to receive sham, and vice-versa, the number of sessions remained the same (10 weekly sessions). Phase III, during the interval between Phase II and Phase IV, there was an interval of 4 weeks of washout. Phase V: laboratory tests and other qualitative measurements. Results: There was no difference beween both the groups in all criteria of evaluation pré treatment, with only na exception: in the Group II there was large inflammatory cell counts. However, there was a significant reduction in eosinophils (p = 0.035) and neutrophils (p = 0.047), and increase of macrophages (p = 0.001), improved peak-flow measurement in the morning (p = 0.01) in Group II (started with sham) in Phase IV. In Daily Symptons Score, there was a significant reduction in use of rescue medication (p = 0.043) in Group I (real acupuncture) in Phase II and after received sham acupuncture (Phase IV), there were less cough (p = 0.007), less wheezing (p = 0.037), less dyspnea (p < 0.001) e less use of rescue medication (p < 0.001). In Group II, after received sham (Phase II), there were less cough (p = 0.037), less wheezing (p = 0.013) and less dyspnea (p = 0.014). In Phase IV, less cough (p = 0.040), wheezing (p = 0.012), dyspnea (p < 0.001) and less nocturnal awakening (p = 0.009). In the questionnaires of quality of life SF-36 and QQL, several domains were found to be improved after received sham acupuncture in both groups, comparing phase II against phase I, but the results found after received real acupuncture were better than sham in both groups. Although there was no statistic difference between both groups. However, there was no difference in exhaled NO and spirometry measurement. Conclusion: This survey demonstrated that the use of real acupuncture in a group of patients with large inflammatory cells counts could have contributed to reduce symptoms, improve quality of life, improved peak-flow measurement in the morning and reduced inflammatory cells count in induced sputum, therefore, acupuncture is a safe healing techniques, presented no adverse effects observed in this study, and could of great help in treatment of patients with mild and moderate asthma

Prevenção do remodelamento ventricular esquerdo induzido pelo decanoato de nandrolona / Prevention of left ventricular remodelling induced by nandrolone decanoate

Maria Cecilia de Toledo Damasceno 13 January 2003 (has links)
Os esteróides anabólico-androgênicos (EAA) são derivados da testosterona que foram desenvolvidos para o tratamento de determinadas condições médicas. Hoje as utilizações feitas por atletas com objetivo de melhorar o desempenho esportivo e por não atletas interessados em melhorar a força física e a aparência vem chamando mais a atenção. O aparecimento do remodelamento ventricular está associado ao uso de EAA. Neste estudo, caracterizamos o remodelamento ventricular que ocorre com o uso de um EAA e avaliamos sua relação com a administração concomitante de um IECA. Os achados mostram que os EAA causam remodelamento ventricular e que o enalaprilato na dose e tempo empregados não exerceu o efeito cardioprotetor e reparador esperado / Anabolic androgenic steroids (AAS) are testosterone by-products that were developed for treating certain medical conditions. Today its non-medical uses attract more attention, such as its use by athletes to improve their performance in sports and by non-athletes interested in enhancing their physical strength and appearance. The emergence of ventricular remodelling are associated to the use of AAS. This study describes the ventricular remodelling that takes place with the use of AAS and evaluates its relation with the concomitant administration of ACEI. These findings show that AAS cause ventricular remodelling and that enalaprilate at the dose and for the time used in this study did not have the expected cardioprotective and repairing effect

Hiperparatireoidismo secundário: fatores prognósticos de recidiva atribuída ao implante após paratireoidectomia total e auto-implante\" / Secondary hyperparathyroidism : prognostic factors of graft-dependent recurrence after total parathyroidectomy and parathyroid autotransplantation

Sérgio Samir Arap 27 October 2005 (has links)
Nos casos de hiperparatireoidismo secundário onde não é possível o tratamento clínico, é indicada a paratireoidectomia. No Serviço de Cirurgia de Cabeça e Pescoço do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo, o tipo de cirurgia utilizada é a paratireoidectomia total com auto-implante de paratireóide em membro superior. Nesses casos, ao contrário da paratireoidectomia total, pode haver recidiva do hiperparatireoidismo no sítio do implante, com sintomas sistêmicos e com necessidade de intervenção para retirada do tecido hiperplásico. Já na paratireoidectomia total, há hipoparatireoidismo definitivo e risco de doença óssea adinâmica. O presente estudo tem como escopo avaliar os pacientes submetidos a paratireoidectomia com implante e esclarecer se há fatores clínicos e de imunohistoquímica que possam indicar antes da cirurgia algum risco de recidiva no implante / When clinical treatment of secondary hyperparathyroidism fails, parathyroidectomy is mandatory. Total parathyroidectomy and immediate parathyroid autotransplantation in the forearm is the treatment of choice at Head and Neck Surgery of Hospital das Clínicas of University of São Paulo Medical School. In this cases, recurrent hyperparathyroidism may be caused by hyperplastic graft tissue. Without autotransplantation, adinamic bone disease may occur. The present study seek to evaluate patients submitted to total parathyroidectomy and autotransplantation and try to clarify clinical or immunohistochemical

Ecological Influences on Weight Status in Urban African-American Adolescent Females: A Structural Equation Analysis

Stanford, Jevetta 01 January 2012 (has links)
The present study employed a quantitative, non-experimental, multivariate correlational research design to test a hypothesized model examining associative paths of influence between ecological factors and weight status of urban, African-American adolescent females. Anthropometric and self-report survey data of 182 urban, African- American adolescent females were collected during after-school programs, health and physical education classes, and community events in an urban area in northeast Florida. Descriptive analyses were conducted to characterize the study participants based upon their age, study setting, and weight status. A scale reliability analysis was conducted to assess the internal consistency reliability of the sample data using selected measures within the context of the study’s specific population and subsequently guided the structural equation model (SEM) analyses. The SEM path analysis was used to develop two measurement models to control for observed error variance for variables demonstrating poor internal consistency reliability (diet behaviors and nutrition selfefficacy) and a final structural model to test the associative paths of influence between latent (diet behaviors and nutrition self-efficacy) and manifest variables (teacher social support and friend social support) on weight status. The results of the path analysis indicated that both teacher social support and friend social support demonstrated a positive, indirect influence on child weight status through nutrition self-efficacy and diet behaviors following two different and specific paths of influence. Diet behaviors, in turn, demonstrated a positive, direct effect on child weight status. These findings provide clear implications for educational leaders that call for the integration of health behavior change theory into traditional education and leadership practice and actively addressing the childhood obesity epidemic in the school environment by implementing health behavior change strategies at various ecological environmental levels.

Efeitos do treinamento físico contínuo ou intervalado em um modelo experimental de dislipidemia e isquemia miocárdica / Effects of continuous or interval physical training on an experimental model of dyslipidemia and myocardial ischemia

César Cavinato Cal Abad 04 June 2013 (has links)
O infarto do miocárdio (IM) é a doença cardiovascular que mais causa morte e invalidez em todo o mundo. O uso de animais experimentais tem auxiliado a compreender melhor a fisiopatologia e as formas de tratamento do IM. Sabendo que as dislipidemias estão associadas com o IM e que o treinamento físico pode ser prescrito para prevenção e tratamento de doenças cardiovasculares, no presente trabalho, investigamos os efeitos de dois tipos de treinamentos físicos em um modelo experimental de dislipidemia e isquemia miocárdica. Camundongos selvagens (WT) e knockout para o receptor LDL (LDL-/-) foram divididos em oito grupos: a) LDLr-/- sedentário (LDL-S); b) LDLr-/- infartado sedentário (LDL-IM-S); c) LDLr-/- infartado submetido a treinamento contínuo (LDL-IM-C); d) LDLr-/- infartado submetido a treinamento intervalado (LDL-IM-I); e) WT sedentário (WT-S); f) WT infartado sedentário (WT-IM-S); g) WT infartado submetido a treinamento contínuo (WT-IM-C); h) WT infartado submetido a treinamento intervalado (WT-IM-I). Após 60 dias da ligadura da artéria coronária descendente, o treino contínuo constou de corrida a 60% do máximo e o intervalado de 8 tiros de 4min a 80% do máximo e recuperação de 4min a 40% do máximo. Nos animais WT infartados, ambos os treinamentos aumentaram a tolerância ao esforço e provocaram diminuição do balanço simpatovagal e aumento do índice alfa em magnitudes semelhantes. O treinamento intervalado reduziu o número de fibras do tipo II em relação aos grupos WT-S e WT-IM-C, bem como reduziu a quantidade de fibras do tipo II-X em relação aos WT-S. A área de secção transversa das fibras do tipo I foi maior no grupo WT-IM-I do que no WT-IM-S e WT-S. A razão capilar/fibra foi maior nos animais do grupo WT-I do que no WT-S. A fração de ejeção e a fração de encurtamento foi menor no grupo LDL-IM-I em relação aos demais, mas sem diferenças entre os grupos WT-S, WT-IM-C e WT-IM-I. Nos animais LDL-/-, o LDL foi maior e o VLDL menor no grupo LDL-IM-C em relação aos demais. O HDLtg(%) foi superior no LDL-C em relação ao LDL-S. O HDLc (mg e %) do LDL-IM-I foi maior que o do grupo LDL-IM-C, sendo que o HDLc (mg) do LDL-IM-I foi, ainda maior do que o grupo LDL-S. O triglicérides total foi menor no grupo LDL-IM-C do que no LDL-S. Somente o grupo LDL-IM-I diminuiu a FC de repouso em relação ao grupo LDL-IM-S. A PA diastólica foi menor no grupo LDL-IM-S em relação ao LDL-S, enquanto que o grupo LDL-IM-I apresentou PA diastólica maior do que o grupo LDL-IM-C. A variância do intervalo de pulso foi maior no grupo LDL-S somente em relação ao grupo LDL-IM-I. Em conjunto nossos resultados demonstraram que os animais LDL possuem diferenças funcionais e fisiológicas importantes em relação ao WT, especialmente na morfologia muscular, na hemodinâmica e no controle autonômico. Que o IM acarretou prejuízos em ambas as linhagens investigadas e que os dois tipos de TF atenuaram semelhantemente esses prejuízos em grande parte das variáveis analisadas / Myocardial infarction (MI) is a major cause of death and disability worldwide. The use of experimental animals has supported to better understand the pathophysiology and treatment forms of myocardial infarction (MI). Knowing that the dyslipidemia associated with IM and that physical training can be prescribed for prevention and treatment of cardiovascular diseases, the present study investigated the effects of two types of physical training on an experimental model of dyslipidemia and myocardial ischemia. Wild mice (WT) and LDL receptor knockout (LDL-/- ) were divided into eight groups: a) LDLr-/- sedentary (LDL-S), b) LDLr-/- myocardium infarction sedentary (LDL-MI-S), c) LDLr-/- myocardium infarction submitted to continuous training (LDL-MI-C), d) LDLr-/- myocardium infarction submitted to interval training (LDLMI- I), e) sedentary WT (WT-S); f) WT myocardium infarction sedentary (WT-MI-S); g) WT myocardium infarction submitted to continuous training (WT-MI-C), h) WT myocardium infarction submitted to interval training (WT-IM-I). After 60 days of descending coronary artery ligation, the continuous training consisted of running at 60% of maximum, while the interval training consisted of eight sprints of 4 min at 80% of maximum and a 4 min recovery at 40% of maximum. In infarcted WT animals, both training programs increased exercise tolerance and promoted decrease of sympathetic-vagal balance and increase of alpha index in similar magnitudes. Nevertheless, the interval training reduced the number of type II fibers in infarcted WT animals compared to WT-S and WT-MI-C groups, as well as reduced the amount of fiber type II-X compared to WT-S. The cross-sectional area of the fiber type I was higher in the WTMI- I animals than in WT-MI-S and S-WT groups. The reason capillary/fiber was higher in group WT-I than in the WT-S. Ejection fraction and shortening fraction were lower in LDL-MII compared to the others, but with no differences among the WT-S, WT-IMI-C and WT-MI-I groups. About the LDL-/- animals, the LDL was higher and VLDL was lower in the group LDL-MI-C in relation to the others. The HDLtg (%) was higher in LDL-C compared to LDL-S. The HDLc (mg and %) of LDL-MI-I was higher than the LDL-MI-C group, and the HDLc (mg) of LDL-MI-I was even higher than LDL-S group. The total triglycerides was lower in LDL- MIC than in LDL-S animals. Only in LDL-MI-I group the resting HR was decreased in comparison to LDL-MI-S. The diastolic blood pressure was lower in LDL-MI-S in relation to LDL-S, while the LDL-MI-I group presented a higher diastolic BP than the LDL-MI-C group. The pulse interval variance was greater in LDL-S than in LDL-MI-I only. In conclusion, our results demonstrate that LDL animals have important functional and physiological differences compared to WT, especially in relation to muscle morphology, hemodynamic and autonomic cardiovascular control. Furthermore, MI leads to damage in both investigated strains and the two types of physical training attenuate similarly the impairment of most of the analyzed variables

Ekologické aspekty paroplynové teplárny Červený Mlýn / Environmental aspects of steam-gas power station Červený Mlýn

Šilar, Martin January 2011 (has links)
The master’s thesis deals with the environmental aspects of combined heat and power station Červený Mlýn (Red Mill). The introductory part of the thesis focuses on the current production technology and the electricity balance of the power station. The heat and power station (also called combined cycle heat and power plant) is scrutinized in terms of emissions sources, focusing on pollutant emissions to air in the following chapter. In this part of the thesis the quantities of the released emissions, namely solid particulate matter (TZL), sulfur dioxide (SO2), carbon dioxide (CO2) are also calculated. The calculation is worked out according to the valid Czech legislation. Further on, the current production technology of the power station is compared with the best available technologies according to the valid directive 2008/1/EC of the European Parliament and of the Council concerning integrated pollution prevention and control. The last chapter presents the innovative technologies which could possibly be installed to reduce pollution emissions (especially nitrogen oxides - NOx) to air at the heat and power station Červený Mlýn.

Guidelines to facilitate the integration of HIV/AIDS services into primary health care programmes within Vhembe District of Limpopo Province, South Africa

Tshililo, Azwidihwi Rose 18 September 2017 (has links)
PhD (Health) / Department of Public Health / The Government of South Africa in response to a prevalent human immunodeficiency virus (HIV) has adopted an approach of integrating HIV/AIDS service into primary health care, as a key to achieving universal access to antiretroviral treatment (ART). Despite the government’s efforts of integrating HIV service into Primary Health Care (PHC), insufficient numbers of PHC staff and inadequate infrastructure is challenging when integrating HIV/AIDS service into PHC. This study explored the extent of HIV service integration into PHC and whether the clinic/health centre’s environment is enabling to integrate HIV service into PHC. Barriers to HIV/AIDS services integration as well as attitudes of PHC nurses were assessed. The overall purpose of this study was to develop guidelines to facilitate the integration of HIV/AIDS services into PHC in Vhembe district of Limpopo province, South Africa. An exploratory sequential mixed methods design was used. The qualitative data was collected and analysed before and results for qualitative approach used to build a subsequent quantitative phase. The current study revealed that HIV/AIDS services are integrated into every existing programme at the PHC clinic and health centres; these include: Immunisation programme, Family planning, PMTCT and ANC programmes, STIs, minor ailments and chronic illness and TB. The study further revealed that the environments at PHC clinics and health centres are not enabling the integration of HIV/AIDS services into PHC due to insufficient staff and inadequate infrastructure. Guidelines to facilitate the integration of HIV/AIDS services based on the findings was developed. The study recommendations comprise; increasing knowledge of HIV serostatus, accelerating HIV prevention, accelerating the scale-up of HIV treatment and care, creating of enabling environment for the integration of HIV/AIDS services into PHC, nursing education and training and nursing education and training.
