A pessoa idosa com doença crônica não transmissível atendida em serviços de média complexidade na cidade de Natal/RN

The demographic and epidemiological transition process caused by a declining in birth rates and in mortality, also changes occurred in morbidity and mortality is represented by the increasing of the aging population and the raising of chronic diseases. These diseases are characterized by multiple etiologies, risk factors, long latency period, a prolonged evolution, non-infectious origin and it has association with functional impairment and disability. Thus, elderly with chronic non-communicable disease has priority because they belong to a vulnerable group to get affection of comorbidities in aging, with increased demand and spending on health services. This study is aimed to analyse the understanding of elderly people with chronic non comunicable disease in the medium complexity service as a contribution to the improvement of health care in the city of Natal / RN. This is a descriptive and exploratory study with a quantitative approach, carried out at the Specialized Center for Elderly Health Care and at the Pescadores Hospital. The population was composed of 4,180 persons with a sample of 124 elderly aged above 60 years, attended in these medium complexity services. The instrument, a structured form, adapted from a questionnaire for monitoring risk and protective factors for chronic disease of the Ministry of Health. To collect data was was used the interview form containing demographic data, habits, health status and health care services. The results were processed using the Statistical Package for Social Science, version 18.0, analyzed by simple statistics. It was found that most seniors were female, predominantly between 70 and 74 years old, married, with a brown skin tone and Catholic religion, more than half had incomplete basic education, family income between one to two minimum wages and living with their families. Regarding the interviewers lifestyle, 94.4%, of them ate chicken and 97.6%, fruits, it was observed a reduction in smoking, alcoholism habits and physical activity according to the increasing age, 58.1 and 18.5% had insomnia18,5 % used sleeping pills. The elderly (51.6%) reported using services in times of sickness, seeking primary care at first (30.6%), 52% did not receive referral and was looking for free demand (38.7%). The most reported morbidity was hypertension, followed by musculoskeletal disorders. Regarding the difficulties in seeking health services, the delay in treatment and the waiting line were the most cited by the elderly. Almost all of them reported no activities to promote health in these services and those who received individual counseling on chronic diseases. Almost always, the health professionals who care of them, were mostly doctors followed by nurses. Based on the results presented, it is considered that the health services of medium complexity must undergone a more continuous dialogue with other attention level and focus on actions of health promotion and prevention. It is also recommended the necessity for qualified professionals to delivery health care to elderly and the implementation of protocols by a multidisciplinary health team, intending to provide better and continous care for the elderly with chronic diseases. The healthcare professionals who served them, were mostly physicians, followed by nurses. Through the results presented, it is considered that the medium complexity healthcare services need to perform a more continuous dialogue with the other levels of attention focusing attention to the health promotion and prevention actions. It is also recommended the necessity for qualified professionals to delivery healthcare for the elderly, in addition, a protocol implementation for the multidisciplinary health care team, to provide better care, and also the care continuity to elderly with chronic diseases

Efeito do parceiro social sobre a resposta comportamental ao ambiente novo em sagüi comum (Callithrix jacchus)

Algumas pesquisas demonstram que a presença de um parceiro social durante uma situação de risco modula a resposta ao estresse, atenuando seus efeitos negativos. Neste estudo, 8 díades de machos e 8 de fêmeas de sagüi comum (Callithrix jacchus) foram expostos a um ambiente novo, sozinhos e acompanhados de um parceiro de mesmo sexo e idade. Quando submetidos a um ambiente novo em companhia de um animal de mesmo sexo, os machos apresentaram um perfil mais filiativo enquanto as fêmeas foram mais competitivas entre si. Os resultados mostram que a resposta comportamental é sexualmente dimórfica, e que machos e fêmeas utilizam diferentes estratégias quando confrontados com situações desafiadoras no ambiente natural Abstract Some researches demonstrate that the presence of a social partner during a challenging situation modulates the stress response, decreasing its negative effects. In this study common marmoset (Callithrix jacchus) males and females were exposed to a new environment, alone or in companion of a social partner of the same sex and age. When submitted to new environment in companion of a same-sex social partner males showed more affiliation whereas females performed agonistic behaviors. The results show that behavioral response is sexually dimorphic and that males and females used different strategies when facing challenging situations in natural conditions

Estilo de vida e vulnerabilidade social dos adolescentes no Bairro de Felipe Camarão, Natal/RN, 2005

Este estudo descreve o estilo de vida e vulnerabilidade dos adolescentes do bairro Felipe Camarão em Natal-RN, a fim de compreender seus comportamentos, conforme vulnerabilidades identificadas. Foram aplicados 145 questionários semi-estruturados entre os adolescentes de 12 a 18 anos, no período de janeiro, a abril de 2005. O estilo de vida descrito, conforme os dados colhidos, informa que 92,4% sabem da importância de se alimentar bem, 86,9% têm sono preservado; 76,5% têm boa relação com seus pais. Porém, 86,9% afirmaram não haver área de lazer/diversão no bairro, enquanto os 31,0% não responderam sobre higiene corporal; 41,4% consomem drogas lícitas (maioria álcool), enquanto 37,9%, as ilícitas (maioria cola); 51,7% dizem que não conversam sobre sexo, enquanto 30,3% conversam com suas mães; 38,0% estão sexualmente ativos, iniciados entre 13 a 16 anos. Os comportamentos de alguns adolescentes estudados indicam um estilo de vida saudável, enquanto outros demonstram justamente o contrário, através de práticas como: pouca participação no lazer, por falta de opção; consumo de drogas lícitas e ilícitas; a falta de diálogo com os pais sobre sexo; relacionamento sexual precoce, somados às condições econômicas e sociais desfavorecidas que os expõem à adoção de um estilo de vida que implica em vulnerabilidade

Prevalência da infecção por HPV e perfil das mulheres frente ao exame de papanicolau no município de São José de Mipibú/RN.

The Human Papillomavirus (HPV) infection is the major sexually transmitted disease all over the world. There are many factors associated to infection and the virus persistency in the organism. This study aims to evaluate the women's knowledge, attitudes and practice about the Papanicolaou test (Pap), as well as analyze the HPV and Chlamydia trachomatis infections prevalences in sexually active women from the city of São José do Mipibu/RN/Brazil. This research was divided in two steps (step I and step II), using different methodologies and samples each. The samples collected in each step, even socio-demographic or from uterus cervix, are from different patients e were analyzed separated. In step I was evaluated 267 rural and urban zone women s knowledge, attitudes and practices about the Pap by home interview. In the step II were included 605 women with age ranged from 15 to 71 years old, with mean of 33,5 years old and from each one were collected two cervical samples, one for Pap and other for molecular biology, beside the epidemiological interview to investigate the correlation between prevalence of HPV infection and risk factors. To molecular analyses, the samples were processed using a mammal rapid DNA extraction technique protocol. For C. trachomatis DNA detection were used the CP24/27 primers, and GP5+/GP6+ to HPV. PCR products were analyzed by electrophoresis on 8% polyacrylamide gels, followed by silver staining. The results of the step I showed that, in spite of only 46,1% of the interviewed women they have demonstrated to possess appropriate knowledge on the Pap test, the attitude and practice proportions were significantly larger, 63,3% and 64,4% respectively. The largest education degree presented association with adaptation of the knowledge, attitudes and practice, while neglect, lack of solicitation of the exam for the doctor and shame, came as main barriers for the accomplishment of the exam. In the stage II the HPV general prevalence was 28,9%, being 26,7% in the women with normal cytology or benign alterations, 26,7% in the ones that had atypical squamous cells of undetermined significance (ASC-US) and 80% in those with Low grade squamous intraepithelial lesion (LSIL). the HPV infection prevalence was larger in the patients with up to 30 years of age and in the unmarried women, and those that had more than one sexual partner presented larger infection risk. The results show that the sexual relationship with multiple partners increased the infection risk for HPV and consequently the possibility of the occurrence of lesions uterine cervix

Estrutura da população de Coleodactylus natalensis Freire, 1999 (Squamata: Sphaerodactylidae) no Parque Estadual Dunas de Natal, Rio Grande do Norte, Brasil

Coleodactylus natalensis Freire, 1999, an endemic species of Atlantic Forest fragments around the Natal municipality, Rio Grande do Norte State, Brazil, has as type locality the Parque Estadual Dunas de Natal (05º48 S to 05º53 S and 35º09 W to 35º12 W), one of the largest restinga (herb and shrub association on sand dunes along the Brazilian coastline) associate fragment, surrounded by urban zone, placed on setentrional Atlantic Forest limits. We made estimates on populational density, spatial distribution, habitat and microhabitat preferences and feeding ecological aspects like sazonal and sexual variations on diet, prey electivities and niche breadth. We randomly sampled ninety-six 50m2 quadrants in each of the four habitats identified in the study area. Were collected 49 specimens and their stomach contents were analyzed; prey items found were correlated with leaf-litter invertebrates from habitat samples. We found a 98,5 ± 75,5 individuals/ha density, in grouped distribution pattern on densest habitats and random distribution on others habitats. This species lives mostly on leaf-litter in forest habitats, in higher humidity points, with lower temperatures, deeper leaf litter and lower sea level elevations than the randomly chosen points in the study area. Isopoda and Aranae were the most important prey categories in numeric, frequency and volumetric terms. Niche breadth has an intermediate value and was variable in sexual and in habitat terms. There was no correlation between morfometric measures and prey size on diet. The C. natalensis population studied seems to be diet opportunist, although selects larger prey items. The Parque Estadual das Dunas do Natal has several indications of anthropic pressure from the surrounding urban area that may affects the local C. natalensis population. Thus, the fragility of this species calls for urgent conservation efforts

Prevalência da infecção por papilomavírus humano, herpes simplex tipo 1 e 2 e Chlamydia trachomatis em um segmento da população feminina da grande Natal/RN

Sexually transmitted diseases (STDs) are among the largest public health problems, especially in developing countries. The acquisition of these infections during early sexual activity is common and many infections have a benign course. However, in some pathogens remain in the state of latency can be reactivated and cause productive infection that may progress to severe forms. In addition, some of them are transmitted vertically resulting in congenital infection, causing immediate damage or long-term child. The classic risk factors for sexually transmitted agents are: early onset of sexual and reproductive health, multiple sexual partners throughout life, use of oral contraceptives and co-infections with different pathogens. We present the results of a cross-sectional study aimed to estimate the prevalence of genital infection by human papillomavirus (HPV), Herpes simplex virus (HSV) and Chlamydia trachomatis (CT) in a segment of the female population of the metropolitan area Christmas, among those who enrolled voluntarily sought, Basic Health Units for the examination of cancer screening cervix in the period 2008 to 2010. All participants, a total of 261 women answered a standard questionnaire by which identified the socio-demographic characteristics, classical risk factors for STDs, reproductive and sexual activity and smoking. Of each patient were obtained two samples, one for the completion of the Pap test for detection of cellular changes and the other processed for DNA extraction and analyzed by PCR (polymerase chain reaction) to detect the three pathogens studied. The population of the study was composed of sexually active women aged between 13 and 79 years, mean 38.7 years, most of them being married, low education levels and low incomes. The majority (87%) had normal results on cytology and only 2.7% had low-grade cytological abnormalities. Prevalence rates were 37.9% for HPV, 4.6% for CT and 26% for HSV. HPV prevalence was higher in women under 25, unmarried and in those who had multiple sexual partners. Women with simultaneous infection by HSV-1 and 2 had higher prevalence of HPV infection. The prevalence of HSV infection showed no association whatsoever with the risk factors analyzed and HSV-1 was the predominant type among the cases of genital HSV infection. The overall prevalence of C. Trachomatis was relatively low, thus providing greater value in younger women aged less than or equal to 20 years

Prevalência da infecção genital pelo vírus herpes simples tipo 1 e 2 em mulheres grávidas e não grávidas de Natal/RN

Herpes simplex is a virus that can be transmitted sexually and is potentially associated with vertical transmission. This study evaluated the prevalence of genital infection by herpes simplex virus (HSV) types 1 and 2 in pregnant and nonpregnant care in the city of Natal / RN, including a total of 222 women, 92 pregnant and 130 nonpregnant. The participants answered a questionnaire to obtain data and socio-demographic characteristics, as well as potential risk factors for sexually transmitted diseases. After the interview, we collected two cervical specimens, one for the Pap test and the other for DNA extraction and analyzed by polymerase chain reaction (PCR) to detect both virus serotypes. Then the women underwent a clinical examination by colposcopy. For statistical analysis, we used the chi-square and logistic regression by SSPS 17.0 Statistic. Most women were up to 30 years of age, nonwhite ethnicity, married, elementary education, family income below the poverty level; initiated sexual activity with age up to 18 years; had more than one sexual partner lifelong and was not pregnant, but has had at least one child. The HSV-1 showed a prevalence of 26.1% among pregnant women and 30.0% in non-pregnant women. While HSV-2 prevalence was found with 10.9% and 19.2% in pregnant and nonpregnant women, respectively. The largest proportion of morphological changes of the uterine cervix was detected among nonpregnant women, both in cytology and in colposcopy. The women were nonwhite ethnicity, married, became pregnant aged less than or equal to 18 years and who had one to two pregnancies had a lower risk of acquiring genital HSV infection. There was a high prevalence of genital HSV infection, HSV-1 is more prevalent than HSV-2. No association was found between morphological changes of the uterine cervix and the presence of the virus in pregnant and nonpregnant women, nor between genital HSV infection and the classic risk factors for sexually transmitted diseases

Prevalência da infecção por Chlamydia Trachomatis em mulheres atendidas no Programa de rastreamento do câncer de colo do útero

Genital infection with Chlamydia trachomatis is now recognized as one of the most prevalent sexually transmitted infections (STDs). Despite major advances in laboratory diagnosis techniques, primarily the character of asymptomatic chlamydial infection in both men and in women constitutes the basis for the formation of reservoirs that perpetuate transmission and acquisition of this and other STDs. The asymptomatic in women favors the rise of infection to the upper genital tract, causing injuries that can result in infertility. An examination of population screening for early detection and treatment of asymptomatic infections is the key step in combating this major public health problem. The present study aimed to evaluate the prevalence of infection by C. trachomatis in sexually active women attended the screening program for cervical cancer of the uterus in health facilities in municipalities in different regions of the State of Rio Grande do Norte, and identify factors that may contribute to the spread of this pathogen and its relationship with the lesions of the uterine cervix. It is a cross-sectional study aimed at detecting the presence of genital tract infection by C. trachomatis either in isolated form or in association with human papilloma virus (HPV) infection in asymptomatic women. Were included in this study, a total sample of 1,134 women aged 13-76, mean 34.4 years, from March 2008 to September 2012. Specimens containing exfoliated cells of the epithelium of the uterine cervix were analyzed by examining Pap cytology for the detection of possible injuries, and the polymerase chain reaction (PCR) for detection of plasmid DNA from C. trachomatis and HPV. Infection with C. trachomatis was detected with overall prevalence rate of 8.1% in the isolated form and 2.8% in co-infection with HPV. The infection was detected in 7.4% of women with normal cytology 11.5% of those with atypical cells of undetermined significance (ASC-US) and 16.7% of those with low-grade squamous intraepithelial lesion (LSIL). We observed an association between C. trachomatis and incidence of low-grade squamous intraepithelial lesion (LSIL). The genital tract infection by C. trachomatis alone was associated with education level, ethnicity and parity, revealing that women with higher education, those of non-white ethnicity and those who had three or more pregnancies were more likely to acquire infection. Levels very close to statistical significance were observed for chronological age, age at first sexual intercourse and first pregnancy. There was no association with marital status, number of sexual partners. Co-infection with C. trachomatis and HPV was detected in 2.3% of women with normal cytology, who had 5.1% in ASC-US and 10.4% in those with LSIL. No association was found between infection C. trachomatis and increased risk of HPV infection, but women with simultaneous infection by both pathogens showed greater risk for LSIL. Co-infection was more prevalent among single women, who had in the first sexual intercourse under 18 years and those who had two or more sexual partners over a lifetime

Projeto Prevenir: uma pesquisa acerca das mudanças no perfil das infecções por DST/AIDS, com a perspectiva de detectar pontos vulneráveis da prevenção

Rio Grande do Norte is among the Brazilian States where the tourism and sexual violence increasingly grow in the country, occupying 4th place in 2004. Associated to this fact, it comes the problematic one of the contamination of the women by Sexually Transmitted Disease (STD). Studies in Brazil have presented a considerable increase of the STDs, caused through lack of suitable protection in the sexual relationships. Due to the biological and psychosocial vulnerability, besides failures or inconsistencies in the condom use associated to the raised taxes of sexual activity with different partners, the STDs constitute the main risk of health. Many difficulties are found by the confrontation of this problem. In this context, this project had as aim to evaluate the vulnerability of this population of sexually active women in Natal-RN Ponta Negra neighbourhood to the infections by STDs, such as, Candida sp., Vaginoses Bacterial, Trichomonas Vaginalis and Chlamydia sp., arisen with the explosion of the sex market, showing a current statistical panorama. It was possible to detect vulnerable points in prevention through patient anamnesis, where the study it showed: high number of partners (8,3% with more than five), low age of first relationship and not the use of condoms (31,8% sometimes use and 45,8% had not used in the first relationship). Already consolidated by the preventive cytopathologic examination, these data were strengthened by high incidence of causing agents of STDs (58,6%). In this way, it is clear that the sexuality must to be thought on the context of the deep economic and socio-cultural transformations in which pass societies, and mainly the ones concerning to the sexuality exercise and to the sex market. With the profile change of the infections, new demands are placed in relation to the risk factors. Therefore, it can be concluded that the prevention vulnerable points detected as more important had been the deficiency in self-perception and wareness of the risk existence among the studied women

Tuberculose: conhecimentos, representações sociais e experiências da doença na visão do portador

Tuberculosis is considered one of the most ancient human diseases, cases were registered 3900 years before Christ, and it is currently regarded as a serious public health problem in the world due to several factors such as income mismanagement, precarious standard of life and some sort of prejudice comprised by the word tuberculosis. Taking this into consideration, it was developed a descriptive and exploratory study aiming at analyzing the social representations of tuberculosis made by its patient from the Unidades de Saúde da Família (Family Health Units a public health program) in Campina Grande City PB, in relation to the decentralization of the policies that administrate the disease. It was interviewed 34 tuberculosis patient that were being treated from 2007 to 2008. The age group of the interviewees varied from 10 to 60 years old, but most of them were between 36 and 60 years old (58,8%, n=20), some were young adult and adult (21 35 years old), with 11 (32,3%) respondents, and, less frequent, children and teenagers (11 20 years old), with 03 (8,8%) participants. Data was collected through semi-structured interview. The questions that guided the research were elaborated based on the operational recommendations of DOTS strategy; that is: access to laboratory examinations; medication guarantee; directly observed treatment. Besides that, the experiences of the patient were considered in their relation with the family and the different social groups. The analysis of the discursive material was submitted to the Analyse Lexicale par Context d un Ensemble de Segments de Texte software - ALCESTE 4.7. Data interpretation showed five categories for the social representations of the tuberculosis patient that participated in DOTS strategy: 1) the accessibility of the health assistance service; 2) the patient perspective of the disease; 3) the change in the operation of the productive life; 4) the signals and symptoms of the tuberculosis disease; 5) the rearrangement and mechanisms used to face the disease. The Central Nucleus reveals that tuberculosis is a transmissible disease that can be prevented by people through educational practices, health promotion, active search for symptomatic respiratory and control of the carriers communication; these mechanisms should be incorporated to the routine of all participants of the family health groups. The Intermediate Elements, based on quotidian life, as well as the individual experiences of the tuberculosis patient, reveals prejudiced attitude and beliefs that lead to isolation and restriction of interpersonal relationship. Peripheral Elements were constituted by themes that showed the patient feelings of indignation because of the social barriers they had to face in the Family Health Units during the treatment. These elements demonstrate a negative perspective of the representation concerning the accessibility, i.e. inadequate structure of the health service; long distance to the Health Centre, this factormakes it difficult for the patient to continue the treatment; scheduling delay; and limited service regarding other requests (doctor, dentist etc). One expects to contribute for the construction of a new perspective of the health question between the different agents who make the assistencial institutions and formation of professionals, either in central or local scope

Papel de sinais cromáticos na identificação de parceiros sexuais em sagüi comum (callithrix jacchus)

The literature concerning color vision shows a trichromatic advantage in detecting ripe fruits and young leaves, but there are contradictory results. There is also the suggestion of this type of vision being adapted to perceive socio-sexual signals. Indeed, Old World primates utilize the skin color of conspecifics as a factor of attraction. But in New World primates there is no record of a coloration signal in the body that can be utilized by other group members. The present study aims to: 1- test whether there is a relation between coloration of body regions and ovulatory cycle in female Callithrix jacchus; 2- Determine if this species uses visual signals to choose mates that are sexually receptive. We collected feces from six females during one month to quantify progesterone concentration by EIA. Body region coloration was measured using a portable spectrometer and modeled to obtain the quantum catch of each photoreceptor, the opponency channels and chromatic distance between the points in units of JND. We recorded the behavior of six males exposed to three pairs of females with a cycling and a non-cycling female in each pair using a transparent plexiglass apparatus. The color of different body regions presented a correlation between progesterone concentration and the yellow-blue and red-green visual axes, with the genitalia as the region showing the highest correlation. The visual axis more apt to see the color variations was the yellow-blue in dichromats, and in trichromats were the red-green to face, yellow-blue to abdomen and both chromatic axes to genitalia. There was no difference in the signal detectability between trichromats and dichromats, but the perception pattern differed between the phenotypes, with a better signal detection by the dichromat phenotype 562 and the trichromat phenotype 543/562. During the behavioral experiments males presented longer gaze duration in periods of experimental manipulation and gaze duration was always longer towards cycling females compared to non-cycling females. Male locomotion during experimental manipulation was greater than in the control only during the periovulatory period of the female, indicating greater excitement. The behavior of cycling females was more active than the behavior of the non-cycling ones regarding locomotion and touching of the plexiglass division of the apparatus. Male gaze duration to cycling females increased with decreasing progesterone concentration, but none of the coloration parameters was correlated to the mate preference exhibited. This coloration signal can transmit information to animals of the group about fertility of female. Different from the intense red of the genitalia swellings of Old World primates, marmoset female genitalia became more bluish-green in the fertile period. Males chose fertile females and were able to visually identify the periovulatory period of females. Choice is related to progesterone concentration, but our results do not show relation between coloration and mate preference. Maybe some behavioral measure is associated with the choice
