Parenteral Nutrition as a Risk Factor for Central Venous Catheter–Related Infection

BACKGROUND The role of parenteral nutrition (PN) therapy as an independent risk factor for central venous catheter (CVC)-related infection in nonselected adult patients is not well established. The aim of this study was to evaluate PN as a risk factor for central venous catheter-related infection in nonselected adult patients in a general university hospital. METHODS Patients using central venous catheters, exposed or nonexposed to PN, were prospectively followed for development of central venous catheter-related infection. RESULTS One hundred fifty-three patients were studied; 28 developed central venous catheter-related infection. Patients with central venous catheter-related infection presented higher frequency of PN use than patients without infection (60.7 vs 34.4%; p = .010). Multivariate Cox analysis showed that PN (relative risk (RR) = 3.30; 95% confidence interval [CI], 1.30-8.34; p = .012) was the only risk factor for central venous catheter-related infection. Malnutrition (RR = 0.45; 95% CI, 0.15-1.34; p = .152), days of hospitalization before central venous catheter insertion (RR = 1.00; 95% CI, 0.98-1.02; p = .801), and sustained hyperglycemia (RR = 0.49; 95% CI, 0.98-1.21; p = .091) were not significant in the model. Multiple logistic regression revealed that mal-nutrition (odds ratio [OR] = 8.05; 95% CI, 1.85-35.03; p = .005), central venous catheter indication for surgical-related pathology (OR = 7.26; 95% CI, 2.51-21.04; p < .001), sustained hyperglycemia (OR = 4.34; 95% CI, 1.79-10.52; p = .001), and days of hospitalization before central venous catheter insertion (OR = 1.04; 95% CI, 1.01-1.07; p = .004) were associated with PN use after adjustment for Assessment Score Intervention System score (OR = 0.33; 95% CI, 0.14-0.80; p = .014). CONCLUSIONS PN therapy is an independent risk factor for central venous catheter-related infection in nonselected hospitalized adult patients.

Adequabilidade da assistência pré-natal em uma estratégia de saúde da família de Porto Alegre-RS

The study aimed to evaluate the adequacy of low-risk prenatal care, as recommended by the Ministry of Health, concerning the minimum number of consultations, and identify possible associated factors. Prenatal care was evaluated in a historical cohort study of 95 pregnant women. Over 50% of the women underwent six or more prenatal consultations. The beginning of the prenatal care began in the first trimester of the gestation for 52% of the women, 84.2% of the women did all their prenatal medical tests, and only 16.8% had postpartum consultations. Prenatal assistance was considered adequate for 2.1% of the sample. A higher number of prenatal consultation was observed among women who had a partner and who had other children. The records reveal a low adequacy level with all minimum criteria established and few factors seem to explain this scenario.O estudo objetivou avaliar a adequabilidade da assistencia pre-natal de baixo risco, conforme a recomendacao do Ministerio da Saude, quanto ao numero minimo de consultas, e verificar possiveis fatores associados. Avaliou-se a atencao pre-natal de uma coorte historica de 95 gestantes. Mais de 50% das mulheres fizeram 6 ou mais consultas de pre-natal. O inicio do pre-natal ocorreu no primeiro trimestre de gestacao para 52% das mulheres; 84,2% das mulheres realizaram todos os exames de pre-natal e apenas 16,8% realizaram consulta no puerperio. A assistencia pre-natal foi considerada adequada para 2,1% da amostra. Maior numero de consultas pre-natal foi observado entre as mulheres com companheiro e com maior numero de filhos. Os registros demonstraram baixa adequacao a totalidade dos criterios minimos estabelecidos e poucos fatores parecem explicar esse cenario.

Lifetime induced abortion: a comparison between women living and not living with HIV.

Background Studies aimed at understanding the association between induced abortion and HIV are scarce and differ on the direction of the association. This paper aims to show the prevalence of induced abortion in a sample of pregnancies of women living and not living with HIV/Aids, determining variables associated with pregnancy termination and linked to the life course of women and to the specific context of the pregnancy. Methods Data came from a cross-sectional study, using interviewer-administered questionnaire, developed with women that attended public health services in Porto Alegre, Brazil. A generalized estimating equation model with logit link measured the association between determinants and abortion. Findings The final sample was composed of 684 women living with HIV/Aids (2,039 pregnancies) and 639 women not living with HIV/Aids (1,539 pregnancies). The prevalence of induced abortion among pregnancies in women living with HIV/Aids was 6.5%, while in women not living with HIV/Aids was 2.9%. Among women living with HIV/Aids, the following were associated with induced abortion in the multivariable analysis: being older, having a higher education level, having had more sexual partners (i.e., variables linked to the life course of women), having had children prior to the index pregnancy and living with a sexual partner during pregnancy (i.e., variables linked to the context of each pregnancy). On the other hand, among women not living with HIV/Aids, only having a higher education level and having had more sexual partners (i.e., determinants linked to the life course of women) were associated with voluntary pregnancy termination in multivariable analysis. Conclusion Although determinants are similar between women living and not living with HIV/Aids, prevalence of induced abortion is higher among pregnancies in women living with HIV/Aids, pointing to their greater social vulnerability and to the need for public policy to address prevention and treatment of HIV associated with reproductive issues.

The Scale of Self-Efficacy Expectations of Adherence to Antiretroviral Treatment: A Tool for Identifying Risk for Non-Adherence to Treatment for HIV.

Background Identification of risk for non-adherence to treatment is a challenge for personalized care for people living with HIV. Standardized questionnaires of patients’ expectations of their capability to overcome obstacles for treatment adherence may be used as a pre-screening for risk identification. A scale of self-efficacy expectations of adherence to antiretroviral treatment (SEA-ART scale) was previously developed. This study assesses the scale validity in predicting non-adherence to ART in adults living with HIV. Methods and Findings A prospective cohort study applied a 21-item SEA-ART scale to 275 adults in ART treatment at an outpatient public service for HIV in Southern Brazil. ART medications taken were assessed at one-month follow-up; ART adherence was devised as an intake of 95% and more of the prescribed medication. A SEA-ART score was calculated by adding up the scores of all items. Multivariable logistic regression and the Area Under the Receiver-Operating-Characteristic Curve (AUROC) were applied to examine the ability of the SEA-ART score to predict non-adherence at follow-up. The SEA-ART score varied from 21 to 105; mean 93.9; median 103.0. Non-adherence was 30.3% (n = 81/267). The odds of non-adherence was 8% lower for each unit increase of the SEA-ART score; after adjustment for age, sex, formal education and time in treatment (OR = 0.92; 95%CI 0.90–0.95; LRT for linear trend, p = 0.002). The AUROC was 0.80 (95%CI 0.73–0.87; p<0.001). The SEA-ART optimal cut-off value was 101, providing a sensitivity of 76.5%, a specificity of 73.1%, a positive predictive value of 55.4% and a negative predictive value of 87.7%. There was no evidence of difference in sensitivity, and specificity among groups organized by age, gender, formal education and time in treatment. Conclusions The SEA-ART scale appears to have a good capacity to discriminate between adherents and non-adherents at one-month follow-up. Further studies should confirm these results in other populations.

Post-diagnosis abortion in women living with HIV/Aids in the south of Brazil

OBJECTIVE To understand how the HIV diagnosis combines with other factors that influence the decision to abort. METHODOLOGY Data were collected during a crossover study of women aged between 18 and 49 years old and seen in public health services in Porto Alegre, Brazil. The life stories of 18 interviewees who had post-diagnosis abortion were reconstructed on a timeline, using information collected quantitatively. RESULTS The time between the diagnosis and abortion was 2 years or less for more than half of the women. For some, post-diagnosis abortion did not mean the end of reproductive life. The most frequent reason for terminating pregnancy was to be living with HIV; however, only some of the women who stated having this motivation did not have post-diagnosis children. Changing partners between pregnancies was a recurring finding; however, in most pregnancies that ended in abortion, the women lived with their partners. DISCUSSION The analysis of the reproductive trajectory of the women studied showed that there is no specific profile of the woman who aborts after receiving the HIV diagnosis. Although this diagnosis may be involved in the decision to terminate a pregnancy, it does not necessarily result in the end of a womans reproductive trajectory. Thus, abortion should be understood within a diversity of decision-making processes and the specific moment of a womans life story.

Desenvolvimento e validação de um índice de vulnerabilidade social aplicado a políticas públicas do SUS

The article outlines the development and initial validation of a Social Vulnerability Index (SVI) including five social determinants of risk to health and demonstrates its application in the financing of primary care by the Unified Health System (SUS) in the State of Rio Grande do Sul. Municipal indicators of vulnerability relating to poverty and population dispersion were obtained from the 2010 population census of the Brazilian Institute of Geography and Statistics. Both exploratory and confirmatory factor analysis suggests that the five items can constitute a reliable and acceptable measurement scale. The SVI-5 was then generated based on the first main component, measuring municipal inequalities in social vulnerability relating to poverty and population in the territory in Z-scores. The external validity of SVI-5 was examined in relation to health outcomes using DATASUS 2007-2011 data, revealing that infant mortality and hospitalizations for conditions treatable by primary care are greater in more vulnerable municipalities The results suggest that the SVI-5 is a valid measure of inequalities in social vulnerability between municipalities, applicable to socially equitable policies in health.

Socioeconomic and regional inequalities of pap smear coverage.

Objectives To identify socioeconomic and regional inequalities of pap smear coverage in the state of Rio Grande do Sul. Methods An ecological study based on data of the 2011-2012 national health information system to estimate the annual coverage of pap smears for the overall female population of the state and for women without private health insurance. We estimated annual pap smear coverage according to the Municipal Social Vulnerability Index and health macro-regions and regions of the state. Results The percentage of women without private health insurance ranged from 38.1% to 94.2% in the health regions. Pap smear coverage was 17.3% for the overall female population and 23.8% for women without private health insurance. Pap smear coverage was higher in more socially vulnerable municipalities and regions with a higher percentage of women with private health insurance. Conclusions The prevalence of private health insurance should be considered in studies that address the coverage of the Brazilian Unified Health System (SUS).Objectives To identify socioeconomic and regional inequalities of pap smear coverage in the state of Rio Grande do Sul.

Factors associated with post-diagnosis pregnancies in women living with HIV in the south of Brazil

Objectives To analyze the factors associated with the occurrence of pregnancies after the diagnosis of infection by HIV. Methods Cross-sectional study with women of a reproductive age living with HIV/AIDS cared for in the public services of the city of Porto Alegre, in southern Brazil. The data was analyzed from a comparison between two groups: women with and women without pregnancies after the diagnosis of HIV. Poisson regression models were used to estimate the reasons of prevalence (RP). Results The occurrence of pregnancies after the diagnosis of HIV is associated with a lower level of education (RP adjusted = 1.31; IC95%: 1.03–1.66), non-use of condoms in the first sexual intercourse (RP = 1.32; IC95%: 1.02–1.70), being 20 years old or less when diagnosed with HIV (RP = 3.48; IC95%: 2.02–6.01), and experience of violence related to the diagnosis of HIV (RP = 1.28; IC95%: 1.06–1.56). Conclusions The occurrence of pregnancies after the diagnosis of infection by HIV does not indicate the exercise of the reproductive rights of the women living with HIV/AIDS because these pregnancies occurred in contexts of great vulnerability.
