Prevention of systemic arterial hypertension under the perspective of users of a family health unit
Objective: understanding how users who attended a group of preventive actions in a Unit Family Health see hypertension and ways to prevent it. Method: this was a descriptive and exploratory study, with a qualitative approach, performed in a Unit of Family Health in João Pessoa/Paraiba, with the participation of 20 users using a semi-structured interview containing questions about demographic profile, knowledge about hypertension and its prevention. The data collected in the interviews were subjected to thematic content categorical analysis. Results: before the questioning of what hypertension is, in 60% of participants there is knowledge about what it is, while 40% do not know what is. Conclusion: it is increasingly necessary providing opportunities for people to gain the autonomy needed for decision-making on matters that affect their health, through knowledge and information
Effect of chemotherapy perception pictures of mastectomized women
The antineoplastic drugs used in systemic treatment of cancer by interfering with the
mechanisms of survival, and cell migration proliferation. By systemic, these drugs can
reach the central nervous system causing possible reactions in normal cells, including
regions of the visual cortex, responsible for visual perception. The role of contrast
sensitivity (FSC) has been used to characterize the process by which the visual system
processes the information of the various frequencies of stimuli received by sensory stimuli
perceived. So, this study aimed to investigate whether the agents of antineoplastic drugs
can alter the sensory threshold in women that used for the systemic treatment of breast
carcinoma, using the FSC as a tool. Respecting ethical aspects necessary to conduct the
study, 20 volunteers participated in the tests, with normal or corrected visual acuity, ten
users of antineoplastic drugs administered in six cycles of the FAC scheme - 5-
fluorouracil, doxorubicin and cyclophosphamide (Experimental Group, EG) and ten
volunteers without condition and without identifiable antineoplastics use of drugs (Control
Group, CG). Measures of sensory threshold were performed at the Laboratory of
Perception, Neuroscience and Behavior, using visual stimuli of spatial frequencies of 0.25,
1, 4 and 8 c/deg (cycle per degree of visual angle). The stimuli were generated in shades of
gray and on a video monitor at 150 cm from the screen. It used to be an experimental
design with repeated measures and put psychophysical forced-choice with two alternatives
of choice. The procedure for measuring the sensitivity was the presentation of successive
pairs of simple stimuli (test and neutral) and the volunteers were asked to choose among
them always, that contained the frequency space. Three consecutive correct responses were
necessary to reduce the amount of contrast in a indeed and an error to increase it (20%).
Each frequency space was estimated twice for each participant, generating 240 values of
thresholds for contrast. The data were grouped into tables and spreadsheets in Microsoft
Office sociodemographic profile of the second sample, the iron values of contrast for
maximum and minimum frequency space for the two groups.The analysis of variance for
measures spread showed a significant difference between the threshold contrast of EG and
the CG (F (1,238) = 23.97, p<0001), in the other words, there was variation in contrast
sensitivity between the groups. At the highest spatial frequency (8 cpg) women in the
control group were 1.6 more sensitive than the experimental group, analyzing how the
post-hoc Tukey test (p<0001). You can guarantee, then, that the variation in contrast
sensitivity among women of EG and CG can be caused, possibly by using the FAC scheme
administered for the treatment of breast carcinoma. Therefore, the hypothesis that women
mastectomized when subjected to treatment with drugs antineoplastics may have changed
their visual perception is confirmed and accepted.Coordenação de Aperfeiçoamento de Pessoal de NÃvel Superior - CAPESAs drogas antineoplásicas são utilizadas no tratamento sistêmico do câncer por
interferir nos mecanismos de sobrevivência, proliferação e migração celular. Por via
sistêmica, estas drogas podem atingir o sistema nervoso central causando possÃveis reações
em células normais, inclusive nas regiões do córtex visual, responsáveis pela percepção
visual. A Função de Sensibilidade ao Contraste (FSC) tem sido utilizada para caracterizar o
processo pelo qual o sistema visual transforma as informações das várias freqüências do
estÃmulo sensorial recebido em estÃmulo percebido. Assim, o presente estudo teve como
objetivo investigar se os agentes das drogas antineoplásicas podem alterar o limiar sensório
em mulheres que a utilizaram para o tratamento sistêmico do carcinoma mamário,
utilizando a FSC como instrumento. Respeitando os aspectos éticos necessários para a
realização da pesquisa, participaram dos testes 20 voluntárias, com acuidade visual normal
ou corrigida, dez usuárias de drogas antineoplásicas administradas em seis ciclos do
esquema FAC - 5-fluorouracil, doxorrubicina (adriamicina) e ciclofosfamida (Grupo
Experimental, GE) e dez voluntárias sem patologia identificável e sem uso de drogas
antineoplásicas (Grupo Controle, GC). As medidas de limiar sensório foram realizadas no
Laboratório de Percepção, Neurociências e Comportamento, utilizando estÃmulos visuais
de freqüências espaciais de 0,25; 1; 4 e 8 cpg (ciclo por grau de ângulo visual). Os
estÃmulos eram gerados em tons de cinza e apresentados num monitor de vÃdeo a 150 cm
de distância da tela. Usou-se um delineamento experimental com medidas repetidas e o
método psicofÃsico da escolha forçada com duas alternativas de escolha. O procedimento
para medir a sensibilidade consistiu na apresentação sucessiva simples de pares de
estÃmulos (teste e neutro) e as voluntárias foram orientadas a escolher sempre dentre eles,
aquele que continha a freqüência espacial. Eram necessários três acertos consecutivos para
diminuir a quantidade de contraste em uma unidade e um erro para aumentá-la (20%).
Cada freqüência espacial foi estimada duas vezes por cada participante, gerando 240
valores de limiares de contraste. Os dados coletados foram agrupados em tabelas e
planilhas do Microsoft Office segundo perfil sociodemográfico da amostra, valores de
limiar de contraste máximos e mÃnimos por freqüência espacial para os dois grupos. A
análise de variância para medidas repetidas mostrou diferença significante entre o limiar de
contraste do GE e do GC (F (1,238) = 22,73; p<0,001), ou seja, houve variação na
sensibilidade ao contraste entre os grupos. Na freqüência espacial mais alta (8 cpg) as
mulheres do grupo controle foram 1,6 mais sensÃveis do que o grupo experimental,
analisado com o teste post-hoc Tukey (p<0,001). Pode-se afirmar, então, que a variação na
sensibilidade ao contraste entre as mulheres do GE e GC pode ser causada, possivelmente,
pelo uso do esquema FAC administrado para o tratamento do carcinoma mamário.
Portanto, a hipótese levantada de que as mulheres mastectomizadas quando submetidas a
tratamento com drogas antineoplásicas podem ter sua percepção visual alterada está
confirmada e aceita
Risk behavior on HIV transmission in independent elderly people
Objective: The objective was to know the risk behavior of independent elderly people in DST / HIV / AIDS prevention.
Method: Exploratory study with quantitative data approach. Sample was composed of 24 independent elderly people without diagnosis. An elaborate semi-structured interview script was used. The data were analyzed by descriptive statistics, using chi-square and Pearson correlation coefficient. Results: We found 87% female, age group between 60-69 years (62%) and marital status widow (43%).Of the sample, 87% reported knowing the means of transmission of the virus, 79% reported not using condoms and all had some sexual intercourse without the use of condoms.The analysis between the dependent variable "knows how to transmit HIV" and independent "condom use" showed statistical significance (p = 0.014).
Conclusion: It can be inferred that there was a high risk behavior for HIV / AIDS virus acquisition in this sample, since they did not use condoms in their sexual practices, even if they had knowledge about the forms of virus transmission.
