    Abstract Vertical HIV transmission is still an important global public health problem. This study aimed to verify vertical HIV transmission in Rio Branco, Acre, Brazil, and to assess the possibility of its elimination. A cross-sectional study was conducted of HIV in pregnant women and a longitudinal study on the incidence of vertical HIV transmission in pregnant women living in the municipality (county) of Rio Branco in 2007-2015. The cohorts of pregnant women consisted of women who had liveborn children, stillbirths, or abortions. The data were obtained from the Brazilian Information System for Notificable Diseases (SINAN), Brazilian Information System on Live Births (SINASC), Brazilian Mortality Information System (SIM), and Brazilian Hospital Information Systems (SIH). Databases. Probabilistic database linkage was performed with the OpenRecLink software. The authors calculated the HIV prevalence rate in pregnant women, the vertical transmission rate, and the principal associated factors. HIV prevalence in pregnant women showed an upward trend, and the mean prevalence was 0.18%. Variables statistically associated with the occurrence of HIV in pregnant women were maternal age ≥ 20 years (p = 0.007), lower schooling (p = 0.054), and unmarried conjugal status/without partner (p = 0.001). Vertical HIV transmission was 6.9%. Use of antiretroviral therapy (ART) during prenatal care, even among pregnant women that already knew they were HIV-positive, was less than 90%. The elective cesarean rate was less than 60%, and the use of ART during delivery and by the newborn in the first 24 hours showed variations, depending on the period in which the maternal diagnosis was made. Although the strategies for the elimination of vertical HIV transmission are well established, this study's results point to important flaws in the cascade of care for HIV-infected pregnant women in Rio Branco.

    Abstract Aim: To evaluate the effect of delays in stage IA to IIIB cervical cancer treatment initiation and conclusion on hospital-based survival among Brazilian women.
    Methods: A retrospective follow-up study was conducted in a stage IA to IIIB cervical cancer cohort treated from 2012 and 2014 and followed until December 31, 2017 in Rio de Janeiro. Delay in treatment initiation definition was defined based on the Brazilian law of 60 days for treatment initiation after diagnosis. Delay in treatment conclusion was defined based on the literature and sample distributions: < 120/121-200/> 200 days. The endpoint was death(from all causes or cervical cancer). Death causes and dates were obtained by a record linkage procedure between the hospital cancer registry and the Mortality Information System. Global 36-month survival and HRs were estimated by the KaplanMeier method and proportional Cox regression models, respectively.
    Results: From 865 patients, 269(31.1%) died over the median follow-up time of 27 months. Delay on treatment initiation(>60-days) was 92.8%, while the delay in treatment conclusion(>120 days) was 87.5%. Overall survival was 61.3% (<60-days:62.6%; 61-90 days:63.5%). Among stage IIB-IIIB, women treated < 60-days presented 40.1% survival, while 61-90-days had 52.5%, and > 90-days had 53.3%. Delays in treatment conclusion significantly reduced survival[72.2%(<120-days) to 60.7%(>200-days)]. Multivariate analysis showed that delays in treatment initiation did not affect 36-month death risk. Compared to women concluding treatment in < 120-days, those taking 121-200-days or > 200-days showed increases in death risk of 89%(95%CI:1.10-3.24) and 111%(95%CI:1.31-3.39), respectively, regardless of age, stage, treatment protocol, and time to treatment initiation.
    Conclusion: Delays in cervical cancer treatment conclusion (but not treatment initiation) affected 36-month survival and death risk among Brazilians.

    Abstract Background: Averse birth-outcomes still affect newborns worldwide. Although high-quality prenatal care is the main strategy to prevent these outcomes, the effect of prenatal care based on Kotelchuck index combined with consultation contents is still unclear. Thus, this article to evaluate the effect of the quality of prenatal care (PC) process on birth indicators in a cohort of puerperaes who attended maternity hospitals in Brazilian western Amazon, city of Rio Branco, in the state of Acre, Brazil, in 2015.
    Methods: This research was a hospital-based cohort study. The sample consisted of 1,030 women who gave birth in maternity hospitals in the city between April 6 and June 30, 2015. This research was a hospital-based cohort study. The sample consisted of 1,030 women who gave birth in maternity hospitals in Rio Branco between April 6th. and June 30th., 2015. Prenatal care was classified as fully adequate when started ≤4th month; ≥80.0-109% expected consultations for GA according to the Kotelchuck Index; ≥5 records of blood pressure, weight, GA, fundal height, ≥4 records of fetal heart rate, fetal movements or equivalent to 75% of the number of consultations; in addition to recording ABO/RH, hemoglobin, VDRL, urine, glucose, anti-HIV and anti-toxoplamosis during the 1st trimester. The evaluated outcomes were low birth weight (LBW), preterm birth and vertical transmission of human immunodeficiency virus (HIV)/hepatitis/syphilis. Differences between proportions were assessed using the X² test, and the crude and adjusted odds ratios (OR) (95% CI) were estimated using unconditional logistic regression.
    Results: Overall cohort, the outcomes incidences were 8.8% for LBW, 9.2% for preterm birth, and 1.1% for vertical transmission (syphilis/HIV/hepatitis). Crude and adjusted OR showed that inadequate PC increased the risk statistically significant of LBW (ORcrude: 1.84; 95%CI: 0.99-3.44; ORadjusted: 1.87; 95%CI: 1.00-3.52), and preterm birth (ORcrude: 1.79; 95%CI: 1.00-3.29; ORadjusted: 3.98; 95%CI: 1.40-11.29).
    Conclusion: The results draw attention to the importance of quality PC in reducing the risks of LBW, preterm birth, and vertical transmission of syphilis/HIV/hepatitis. Moreover, using this proposed quality prenatal care indicator based on Kotelchuck index combined with consultations contents adjusted by GA may accurately predict unfavorable outcomes.

    Abstract OBJECTIVE To review the main instruments of functional assessment and health status cited in the literature to evaluate Brazilian workers and verify the compatibility of their items with the core set for professional rehabilitation. METHODS A review of the literature was conducted in the main databases in search of articles that used assessment instruments in populations of workers between 2007 and 2017. Subsequently, the contents of the identified instruments were retrieved, and two evaluators analyzed their items to verify the compatibility with the categories of the core set of the International Classification of Functioning for professional rehabilitation. Cohen's kappa coefficient was used to evaluate the agreement between the evaluators. RESULTS Five specific and eight generic instruments were selected to evaluate the functioning of workers. The analysis of the items of the total instruments allowed the definition of 58 categories (64.5%) of the core set with minimal overlap: 13 (76.5%) of the body functions component, 29 (72.5%) of the activities and participation component and 16 (49%) environmental factors. CONCLUSIONS The association of several instruments requires time and makes it difficult to use the classification. The development of instruments with direct association with its categories is essential to operationalize it.

    Abstract This study aimed to assess time trends in colorectal cancer incidence from 1983 to 2012 in Latin America. This was an ecological time-series study whose population consisted of individuals aged 20 years or older diagnosed with colorectal cancer. Data from population-based cancer registries in Cali (Colombia), Costa Rica, Goiânia (Brazil), and Quito (Ecuador), were used for rates estimation, while time trends estimations were proceeded by the Joinpoint Regression Program. The study showed an increase in colorectal cancer incidence in men and women in Cali (2.8% and 3.2%, respectively), Costa Rica (3.1% and 2.1%, respectively), and Quito (2.6% and 1.2%, respectively), whereas in Goiânia, only women showed an increase in colorectal cancer rates (3.3%). For colon cancer, we observed an increasing trend in incidence rates in men and women in Cali (3.1% and 2.9%, respectively), Costa Rica (3.9% and 2.8%, respectively), and Quito (2.9% and 1.8%). For rectal cancer, we observed an increasing trend in incidence in men and women in Cali (2.5% and 2.6%, respectively), Costa Rica (2.2% and 1%, respectively), and Goiânia (5.5% and 4.6%, respectively), while in Quito only men showed an upward trend (2.8%). The study found increases in colorectal cancer, colon cancer, and rectal cancer in four Latin America regions. This findings reflect lifestyle, such as dietary changes, following the economic opening, and the prevalence variations of colorectal cancer risk factors by sex and between the four studied regions. Finally, the different strategies adopted by regions for colorectal cancer diagnosis and screening seem to influence the observed variation between anatomical sites.

    Abstract Objectives: This study aims to estimate a population-based cancer incidence among indigenous populations in the State of Acre, Brazilian Western Amazon, to provide knowledge about cancer epidemiological profiles contributing to healthcare policies and service planning. Although cancer epidemiology in Brazil is well described through incidence and mortality estimate in the general population, cancer estimates among indigenous peoples are still unknown.
    Design: This is a descriptive study of cancer incidence among the indigenous population (2000-2012) in the State of Acre, Brazil. The sources used were population-based cancer registries of Goiânia, hospital-based cancer registry of Acre, São Paulo, and Porto Velho; Special Indigenous Health Districts databases of Acre, Goiânia, and São Paulo; Mortality Information System, and Rio Branco's public and private laboratories' reports. Standardized Incidence Ratio (SIR) was calculated using cancer incidence rates of Goiânia as reference.
    Results: From 137 cancer cases, 51.8% occurred in women and 32.1% in people aged 70 + . Among men, the most frequent cancer sites were stomach (25.8%), liver (15.1%), colorectal (7.6%), leukemia (7.6%), and prostate (6.1%). Among women, the most frequent were cervical (50.7%), stomach (8.5%), leukemia (5.6%), liver (4.3%), and breast (4.3%). Among men, there was an excess of cancer cases for stomach (SIR=1.75; 95%CI:1.67-1.83), liver (SIR=1.77; 95%CI:1.66-1.88), and leukemia (SIR=1.64; 95%CI:1.49-1.78). In women, an excess of cancer cases was observed for cervical (SIR=4.49; 95%CI:4.34-4.64) and liver (SIR=2.11; 95%CI:1.88-2.34). A lower cancer incidence for prostate (SIR=0.06; 95%CI:0.05-0.07) and female breast (SIR=0.12; 95%CI:0.11-0.14) was observed.
    Conclusions: Cervical, stomach, and liver cancers corresponded to 52% of the cases and were highly incident among the Brazilian indigenous population of Western Amazon compared to non-indigenous counterparts. Despite the low frequency of breast and prostate cancer, the fact they were present among indigenous peoples suggests a complex epidemiological transition framework in these populations.

    Abstract Breast cancer survival in Latin America countries is below Central European countries. Hospital-based breast cancer survival studies in western Amazon, Brazil, are lacking. This article aims to estimate hospital-based breast cancer survival in Rio Branco, Acre, and predictor factors. Hospital-based cohort study of all women diagnosed with breast cancer (2007-2012) was proceeded. Information were obtained from medical reports, and follow-up was until 2013. One-, 2- and 5- years breast cancer specific-survival were estimated by Kaplan-Meier method. Crude and adjusted Harzards Ratios (HR) were estimated by proportional Cox regression model. One-, 2-, and 5-year overall breast cancer survival were 95.5%, 83.7%, and 87.3% respectively. Surgery combined to radiotherapy significantly affected 1-, 2-, and 5-year survival (99%, 94%, and 90.6%, respectively) as compared to other treatments (77%,57.1%, and 37.5%, respectively). Comparing to surgery combined to radiotherapy treatment, surgery alone increased the risk of death, independently of age and stage (HR = 7.23;95%CI:2.29-22.83). In Rio Branco, Acre, 5-year breast cancer survival is similar to more developed areas in Brazil. Surgery combined to radiotherapy was independently associated to a lower risk of death as compared to surgery alone and other treatment.

    Abstract Objective To describe the clinical and epidemiological profile of primary thyroid cancer hospital cases in Brazil. Methods This is a descriptive study of cases held on hospital cancer records who had their first consultation for treatment in the period 2000-2016 and who were monitored by the hospitals providing those records. Results Of the 52,912 cases, 83.4% were female and 96.9% were differentiated carcinoma cases. The median time to diagnosis was shorter for anaplastic cases (11 days) and for those living in Brazil's Southern region (5 days). Treatment was initiated within 60 days in 88.8% of cases that arrived at the hospitals without diagnosis and in 34.9% of those who arrived with diagnosis. Conclusion The findings are consistent with thyroid cancer epidemiology, with a predominance of female cases and differentiated carcinomas. Analysis of time-to-treatment suggests access difficulties for those who already had diagnosis when they arrived at the hospitals.

    Abstract Purpose: This clinical trial aimed to evaluate the influence of Mat Pilates and time on the change in fatigue scores in women with breast cancer undergoing adjuvant radiotherapy (RT). Additionally, assess the adherence and adverse effects of Mat Pilates sessions and the association of the level of physical activity with severe fatigue symptoms.
    Methods: One hundred fifty-six patients with non-metastatic breast cancer were randomized to usual care or supervised Mat Pilates exercise. Fatigue and physical activity level were measured at baseline, end of RT, 30 days, 3 and 6 months after RT. The generalized estimating equation (GEE) with intention to treat was applied.
    Results: A significant difference in the fatigue mean between the end of RT and the baseline was found in patients of both groups. There was no adverse effect with the practice of Mat Pilates, and it was analyzed the reduction of the symptom pain after the end of RT in women of intervention group compared to the control. There was no significant effect on fatigue between the groups. Patients with severe fatigue after 3 and 6 months of RT reported a significantly lower level of physical activity in the last periods.
    Conclusion: Fatigue levels increased at the end of RT but returned to baseline values after 6 months. A lower level of physical activity was associated with severe fatigue symptoms. Mat Pilates was safe for these women and reduced the symptom pain after treatment, but it did not successfully reduce fatigue during adjuvant RT.

    Abstract Data on exposure to organochlorine (OC) pesticides in the Brazilian population are lacking. The purpose of this study was to investigate the distribution of serum levels of OC pesticides in Brazilian blood donors and to determine factors potentially influencing exposure levels. To conduct this biomonitoring survey, blood samples were collected from blood donors attending the Hematherapic Unit in Rio Branco, North of Brazil, in 2010-2011. A total of 1183 (99%) subjects answered to a questionnaire including information on sociodemographics, lifestyle, and dietary habits. Twenty four OC pesticides were measured in serum samples from 978 donors (82%). Associations of OC pesticide serum levels and the number of OCs detected per donor with their potential predictors were explored by logistic and Poisson regression, respectively. Of the 24 OC pesticides analyzed, the highest prevalence was observed for p,p'-dichlorodiphenylethane (p,p'-DDE) (32%), followed by lindane (γ-hexachlorocyclohexane) (20%), heptachlor (16%), and p,p'-dichlorodiphenyltrichloroethane (p,p'-DDT) (13%). 95th percentiles of levels of these four OC pesticides were: 3.85ng/mL (p,p'-DDE) (median<0.09ng/mL), 0.09ng/mL (lindane) (median<0.04ng/mL), 0.23ng/mL (heptachlor) (median<0.09ng/mL), and 0.27ng/mL (p,p'-DDT) (median<0.02ng/mL). Factors significantly associated with a more frequent detection of OC pesticides included age, gender, education, and frequency of fish, manioc flour, açai pulp, and Brazil nuts intake. Major predictors of the number of OC pesticides detected were age, marital status, income, education, and frequency of consumption of manioc flour, açai pulp, and Brazil nuts. For the first time in Brazil, a biomonitoring study has assessed the internal doses of OC pesticides in a large sample of the adult population and potential exposure determinants. Except for lindane, which was permitted for use as a wood preservative until 2007 in Brazil, occurrence of OC pesticides was lower than or in the same range as those observed in other countries.
