RESUMEN

This study aimed to determine the main single nucleotide polymorphisms (SNPs) that are associated with an increased or decreased risk of glioma development in healthy individuals. We conducted a systematic review of the articles published in English on the PUBMED database between January 2008 and December 2017. Our search resulted in a total of 743 articles; however, only 56 were included in this review. A total of 148 polymorphisms were found, which involved 64 different genes. The polymorphisms that were most associated with an increased risk of glioma development were polymorphic variants rs179782, rs13181, and rs3791679 of the genes XRCC1, ERCC2, and EFEMP1, respectively.

RESUMEN

BACKGROUND: Sarcomas account for less than 1% of primary breast cancers, and breast angiosarcomas are responsible for only 0.05% of all breast malignancies. The male breast has the same potential for malignant transformation as the female breast. However, due to anatomical differences in the breast and the low incidence of angiosarcoma, it is difficult to determine how male breasts can be affected by this type of tumor. CASE PRESENTATION: A 36-year-old male patient was admitted to the hospital with a palpable lump in his right breast. Lymphadenopathy was negative. Ultrasonography showed a hypoechoic mass with partially defined contours, measuring 4.0 × 3.0 cm, with muscle infiltration. Histological examination revealed a malignant tumor. Radical mastectomy was then performed with clear surgical margins. The patient began chemotherapy with paclitaxel. Following the second cycle of chemotherapy, he presented with headache and seizures due to a frontal lobe metastasis. Twenty days after the onset of neurological symptoms, the patient died. CONCLUSIONS: Primary angiosarcomas of the male breast are extremely rare. This is the sixth case published in the literature. It is in agreement with other studies in the literature concerning clinical presentation and poor prognosis. Treatment consists in surgical removal of the tumor with clear margins and without axillary lymphadenectomy.

RESUMEN

Our aim is to investigate two major tendencies in nineteenth-century Brazilian alienism: mentalism and organicism, by conducting a descriptive study of original Brazilian documents on medical health treatments in the 1830s, 1840s and 1850s. Primary sources of Brazilian alienism were theses, memoirs, official reports, and documents written by clinicians and asylum directors. We analysed early mental treatment in Brazilian lunatic asylums, exploring the relative contributions of two main theoretical orientations: moral treatment (based on Pinel and Esquirol) and 'medical-organicist therapeutic orientation'. Intertextuality was used to assess reports of medical organicist treatment in Brazil. We concluded that contemporaneous textual sources indicate that mid-nineteenth-century alienism in Brazil was predominantly influenced by organicism exported from European countries. Pinel's mentalist view, nevertheless, remained the reference point for clinical issues associated with the doctor-patient relationship.

RESUMEN

Objective The aim of this paper is to analyse the quality of life (QOL) of undergraduate nursing students. Methods A descriptive cross-sectional study with 206 students conducted in July 2013, in the city of Picos/PI, Brazil. Data were collected using the WHOQOL-BREF questionnaire. The Mann-Whitney and Kruskal-Wallis tests were used to analyse the data with a significance level of 5%. Results The domains with the best average scores were Physical (69.4) and Social Relations (74.3), and the domains with the worst average scores were Psychological (68.5) and Environment (54.2). For the overall assessment, the average was 66.6+10.8. A statistical significance was observed when crossing QOL with number of children (p = 0.029), where students without children performed better. Conclusion These results allow the early detection of difficulties experienced by nursing students and may support strategies that benefit the search for solutions to conflicts that affect QOL.

RESUMEN

AIM: To compare the antimicrobial activity of the chemical substances--70% isopropyl alcohol, 2% glutaraldehyde (GTA) and 0.25% peracetic acid (PAA) in disinfecting orthodontic pliers contaminated in vitro with Streptococcui mutani, Staphylococci aureui and Candida albicani. MATERIALS AND METHODS: Distal end cutter pliers were divided into five groups: group 1 (negative control--sterilized pliers), group 2 (positive control--sterilized plier, subsequently contaminated), group 3 (disinfected with 70% isopropyl alcohol, friction method), group 4 (disinfected with 2% GTA, immersion method for 30 minutes), group 5 (disinfected with 0.25% peracetic acid (PAA), immersion method for 10 minutes). After the pliers were treated with one disinfectant and submitted to microbiological evaluation (by counting colony forming units), they were submitted to the same cleansing, sterilizing and contaminating processes, and were used in the following groups (crossover and washout study). The two-factor analysis of variance (ANOVA) test, followed by the Tukey test, was used to compare the groups. RESULTS: The results showed that there was no statistically significant difference between the three tested disinfectants. CONCLUSION: Although there were no statistically significant differences between the disinfectants, the chemical agents 2% glutaraldehyde and 0.25% PAA were effective in inhibiting the growth of the three microorganisms tested; however, 70% isopropyl alcohol was unable to completely eliminate S. aureui. CLINICAL SIGNIFICANCE: The chemical substances 2% glutaraldehyde and 0.25% PAA completely eliminated the microorganisms tested.

RESUMEN

OBJECTIVE: To verify the association between metabolic syndrome and its components, and intake of antioxidant nutrients in adolescents. METHODS: This is a cross-sectional study of the data of 327 adolescents in a high school in Teresina, Piauí, Brazil, pertaining to their socioeconomic background, anthropometric measurements, dietary intake (selenium; copper; zinc; vitamins A, C, and E), hemodynamics, and biochemical tests. The criteria for diagnosing metabolic syndrome in adolescents were applied. Binary logistic regression was used to verify the association between metabolic syndrome and its components, and intake of antioxidants. The level of significance was established at p<0.05. RESULTS: Prevalence of metabolic syndrome was 7.0%, with a significant association between body mass index and blood pressure. Lower tertiles of copper and vitamins A and E intake were associated with high triglyceride and glycemic levels. The association with vitamins A and E remained after adjustment. CONCLUSIONS: A significant association between lower vitamins A and E intake and metabolic syndrome components (altered triglycerides and glycemic levels) was found. Besides further studies on this issue, the need for health interventions was found, which ensures the appropriate intake of antioxidant nutrients during adolescence.

RESUMEN

OBJECTIVE: To verify the relationship of intermittent fasting in the bodyweight of overweight and obese individuals through a systematic literature review. METHODS: This is a systematic review based on randomized controlled trials. The articles were consulted in the databases: Science Direct, PubMed e BVS. This review was evaluated through the PRISMA recommendation. RESULTS: After the selection process, four articles were included in this review, comparing intermittent fasting (IF) with calorie restriction diet (CRD) as a control group. In 2 studies using similar protocols, there was no significant reduction in body weight of overweight or obese subjects. In the other two studies using different protocols, weight loss was significant in the IF group compared to the CRD group. CONCLUSIONS: Results did not provide evidence of the effect of intermittent fasting on weight loss in overweight or obese individuals.

RESUMEN

Background: Cancer and fibroadenoma are the most common breast tumors in women of reproductive age. Nuclear factor erythroid 2-related factor 2 (Nrf2) and the nuclear factor kappaB (NF-κB) transcription factor play an important role in the inflammatory process and in cell proliferation. However, few studies have analyzed these markers in breast cancer and fibroadenoma in women of reproductive age. Results: Light microscopy showed a higher concentration of anti-Nrf2 and anti-NF-κB-stained nuclei in breast cancer than in fibroadenoma. The mean percentage of stained nuclei for Nrf2 was 7.12 ± 5.2 and 43.21 ± 19.83 in the control and study groups, respectively (p < 0.0001). The mean percentage of anti-NF-κB was 10.75 ± 7.09 and 56.14 ± 21.19 (mean ± standard deviation) in the control and study groups, respectively (p < 0.0001). Histological grade 3 tumors showed a significantly higher expression of Nrf2 and NF-κB than grade 1 tumors (p < 0.05). Material and methods: This study was approved by the Institutional Review Board of Federal University of Piaui and all patients assigned an inform consent term prior to the study initiation. Nrf2 and NF-κB expression was evaluated by immunohistochemistry in 66 patients, divided into two groups, control (fibroadenoma, n = 36) and study (cancer, n = 30). The data were analyzed using ANOVA test and the statistical significance was established at p < 0.05. Conclusion: Nrf2 and NF-κB expression was significantly higher in breast cancer than in fibroadenoma, in addition to having a greater association with more aggressive tumors.

RESUMEN

CONTEXT AND OBJECTIVE: The number of acquired immunodeficiency syndrome (AIDS)-related deaths covers different segments of the population differently, making monitoring of this mortality essential. The aim of this study was to describe the epidemiological situation of AIDS-related mortality in a municipality in the northeastern region of Brazil. DESIGN AND SETTING: Retrospective cross-sectional study based on data from death certificates in the mortality information system of the Health Information Center, Municipal Health Foundation, Brazil. METHODS: Between 2003 and 2013, we investigated death certificates on which AIDS-related mortality was reported. Sociodemographic data, year, place, type of establishment where death occurred and underlying and associated causes that led to AIDS-related death were described. The Mann-Kendall test was used to verify the growth trend of the standardized mortality rate over the period studied. RESULTS: Among the 1,066 AIDS-related deaths, 69.7% were among men; 47.2% of the individuals were 28-41 years of age, 32.7% had had 4-7 years of schooling, 66.9% were pardos (mixed race), 55.7% were unmarried and 15.3% were housekeepers. Hospitals were the site of 97% of the deaths, and 91% occurred at public hospitals. Respiratory failure was the main cause of death. The prevalence of infectious and parasitic diseases was 99.0%. AIDS-related mortality increased by 160% over the period studied, from 5.5/100,000 inhabitants in 2003 to 14.3/100,000 in 2013. CONCLUSION: In the Brazilian municipality studied here, AIDS-related mortality was most prevalent among men and young adults of lower socioeconomic level. Over the period studied, the mortality rate increased.

RESUMEN

Breast cancer is a disease of unknown etiology, whose major risk factors are genetic alterations. Polymorphism of the calcium-sensing receptor (CaSR) has been a focus of some recent studies, due to a probable association with breast cancer risk and tumor aggressiveness. A relationship between polymorphic rs17251221 variant of the CaSR gene, and allele G (considered a gain-of-function mutation) and breast cancer risk has been stressed, despite the paucity of studies found in the literature. The present study involved 137 women (69 women with breast cancer-case; and 68 controls without breast cancer) who had 3 ml of peripheral blood drawn for DNA study. Genomic DNA was extracted from leukocytes by genotyping technique with real-time polymerase chain reaction. The AG genotype (rs17251221) was present in 13 women (18.84%) from the case group and in 8 (11.76%) women from the control group (p = 0.3434), while the GG genotype (rs17251221) did not occur in any group. In contrast, no statistically significant difference was observed between the AG genotype of variant rs17251221 in premenopausal case and control women (p = 0.71). There was also no statistically significant difference between postmenopausal case and control patients (p = 0.6851). In the current study, CaSR gene polymorphism of SNP variant rs17251221 did not show any statistically significant association with breast cancer, in both premenopausal and postmenopausal women.

RESUMEN

A dengue é uma arbovirose considerada de cunho desafiadora para a saúde pública mundial, visto que proporciona prejuízos duradouros, representando, assim, uma ameaça à saúde humana. Dessa forma, este estudo teve como objetivo analisar a distribuição espacial dos casos de dengue no Piauí entre 2015 e 2019. Tratou-se de um estudo ecológico espacial da dengue, com dados do Sistema de Informação de Agravos de Notificação (SINAN) de 2015 a 2019. Foi aplicado o teste de associação X² para a análise bivariada e para análise espacial foi utilizado o software Qgis (versão 3.16.7. Hannover). Nesse período, foram notificados 27289 casos e 21944 casos confirmados de dengue. O município de Teresina (62,9%) e a região de saúde Entre Rios (65,84%) apresentaram os maiores registros. O sexo feminino (58,4%), a faixa entre 20 e 34 anos (33,52%) e a etnia parda (44%) foram os mais afetados. Quanto à escolaridade, 58,5% foram ignorados. Os casos de dengue estão concentrados em polos com grande fluxo populacional. A identificação do perfil epidemiológico, da mesma maneira que os seus principais fatores de risco, é uma forma de auxiliar o sistema de saúde de todo o estado na elaboração de políticas de controle específicas para a população mais vulnerável a doença.


Dengue is an arboviral disease considered global public health challenge, as it provides lasting damage, thus representing a threat to human health. Therefore, this study aimed to analyze the spatial distribution of dengue cases in Piauí between 2015 and 2019. This was a spatial ecological study of dengue, with data from the Disease Notification Information System (SINAN) from 2015 to 2019. The X² association test was applied for the bivariate analysis and the Qgis software (version 3.16.7. Hannover) was used for spatial analysis. During this period, 27,289 cases and 21,944 confirmed cases of dengue were reported. The city of Teresina (62.9%) and the health region Entre Rios (65.84%) had the highest records. Females (58.4%), between 20 and 34 years old (33.52%) and mixed race (44%) were the most affected. As for education, 58.5% did not respond. Dengue cases are concentrated in poles with large population flows. The identification of the epidemiological profile, as well as its main risk factors, is a way to help the health system of the entire state to elaborate specific control policies for the population most vulnerable to the disease.

RESUMEN

Tumor biomarkers such as hormone receptors, HER-2 and Ki-67 are used routinely in clinical practice for classification of molecular subtypes of breast cancer. Cell proliferation evaluated by Ki-67 antigen expression is important to determine tumor aggressiveness. However, there is a paucity of studies comparing Ki-67 expression in an expressive number of cells among molecular subtypes of breast cancer, particularly among less and more aggressive tumors, such as luminal A and triple-negative, which have led us to the present study. The current study included invasive ductal carcinoma samples of 59 patients, which were divided into two groups: luminal A (n = 29) and triple-negative (n = 30). For immunohistochemical reaction, the samples were incubated with monoclonal anti-Ki-67 antibody (clone MIB1) and cells expressing Ki-67 protein were identified by dark brown staining of the nuclei, counting at least 600 cells per slide. The mean percentages of stained nuclei were analyzed by Student's t test (p < 0.05). The mean percentage of nuclei stained with anti-ki-67 was 10.14 and 77.22 in luminal A and triple-negative breast cancers, respectively (p < 0.0001). Our study showed a high cell proliferation of triple-negative breast cancer in comparison with luminal A, justifying its aggressiveness and poor clinical outcome.

RESUMEN

BACKGROUND:: The incidence of skin cancer has increased worldwide, particularly melanoma rates, which had a mean development of 2.6 % a year in the last 10 years. The agreement on the relation between long-term or chronic exposure to the sun and the emergence of these neoplasias has made several workers who perform activities exposed to solar radiation to form a risk group for the development of skin cancer, community health agents included. OBJECTIVES:: To analyze the prevalence of sunscreen-use-related factors to skin cancer in a labor risk group. METHODOLOGY:: Cross-sectional study with community health agents selected through simple random sampling. After collecting data using semi-structured interviews, a descriptive analysis was performed for the qualitative variables, bivariate analysis was employed for checking the association between sunscreen use and sociodemographic, occupational and knowledge about skin variables, and multivariate analysis was conducted to check independent variables associated to sunscreen use. A 5% significance level was used. RESULTS:: Of 261 health gents selected, 243 were able to participate in the study. The prevalence rate of sunscreen use was 34.2% (95% CI: 28.2-40.2). Factors associated with sunscreen use were female sex, advanced age, use of sunscreen in situations when the skin got burnt, knowledge of the negative effects of the sun on the skin and skin cancer history. CONCLUSIONS:: The prevalence found reveals that there is a need for implementing educational strategies in health services regarding photoprotection.

RESUMEN

The main determinants of the risk of mortality in the neonatal period are low birth weight and premature birth. The study sought to analyze the adequacy of prenatal care and risk factors associated with premature birth and low birth weight in a northeastern Brazilian capital. This is a case-control study. A model for adequacy of prenatal conditions composed of four indicators was created. Descriptive statistics for univariate analysis were used; as well as Wald linear trend tests, Student's t and chi-square test for bivariate analysis and multiple logistic regression for multivariate analysis with p <0.05. Multivariate analysis showed that poor education, not performing gainful activity, caesarean section, oligohydramnios, placental abruption and pre-eclampsia are independent factors associated with premature birth and/or low birth weight. For adequacy of prenatal care, variable indicator III remained significant, showing that mothers who had inadequate prenatal care had an increased chance for the occurrence of the outcome, highlighting the need for adequate public health policies of care for pregnant women in the municipality under scrutiny.

RESUMEN

Purpose Identify factors associated with infant mortality by a hierarchical model based on socioeconomic, health care, obstetric and biological determinants in a northeastern Brazilian capital. Methods Observational, retrospective cohort study based on secondary data of births and deaths of infants of mothers living in the city of Teresina. Results Based on the distal level of determination of infant mortality, the characteristics that remained statistically significant were maternal age, maternal education and maternal occupation (p < 0.001). In the intermediate level, all variables were statistically significant, particularly the type of pregnancy and delivery (p < 0.001). The gender of the baby was the proximal level feature that had no significant association with the outcome, while the other variables of this level had association (p < 0.001). Conclusions This study evidenced that, in addition to biological factors, socioeconomic status and maternal and child health care are important to determine infant mortality.

Binary logistic regression was used to verify the association between metabolic syndrome and its components, and intake of antioxidants. The level of significance was established at p<0.05. RESULTS: Prevalence of metabolic syndrome was 7.0%, with a significant association between body mass index and blood pressure. Lower tertiles of copper and vitamins A and E intake were associated with high triglyceride and glycemic levels. The association with vitamins A and E remained after adjustment. CONCLUSIONS: A significant association between lower vitamins A and E intake and metabolic syndrome components (altered triglycerides and glycemic levels) was found. Besides further studies on this issue, the need for health interventions was found, which ensures the appropriate intake of antioxidant nutrients during adolescence.

RESUMEN

AIM: To evaluate the demographic characteristics and clinical phenotypes of inflammatory bowel disease (IBD) in a geographic area in Northeastern Brazil. METHODS: This retrospective study was conducted at the Hospital of the Federal University of Piauí in Northeastern Brazil. Demographic characteristics and clinical phenotypes of IBD were analyzed in relation to the time of diagnostic confirmation, which was defined as the date of disease onset. Data were collected between January 2011 and December 2012 and included all census patients 18 years of age or older during that period for whom there was diagnostic confirmation of Crohn's disease (CD), ulcerative colitis (UC), or unclassified colitis according to the Montreal criteria. We also analyzed the period of time between the onset of clinical manifestations and the diagnosis of IBD (delay in the diagnosis). Statistical analyses included means and standard deviations for numeric variables and the Pearson χ2 adherence test for nominal variables. The annual index occurrence and overall prevalence of IBD at our institution were also calculated, with P values<0.05 indicating statistical significance. This study was approved by the Institutional Ethics and Research Committee. RESULTS: A total of 252 patients with IBD were included, including 152 (60.3%) UC patients and 100 (39.7%) CD patients. The clinical and demographic characteristics of all patients with IBD showed a female to male ratio of 1.3:1.0 and a mean age of 35.2 (SD=14.5) years. In addition, the majority of patients were miscegenated (171, 67.9%), had received higher education (157, 62.4%), lived in urban areas (217, 86.1%), and were under the age of 40 years (97, 62.5%). For patients with CD, according to the Montreal classification, the predominant features present from the onset of disease were an age between 17 and 40 years (A2); colonic disease location (L2); and nonstricturing, nonfistulizing disease behavior (B1). However, approximately one-quarter of all CD patients demonstrated perineal involvement. We also observed considerable delay in the diagnosis of IBD throughout the entire study period (mean=35.5 mo). In addition, the annual index occurrence rose from 0.08 to 1.53 cases/10(5) inhabitants/year during the study period, and the prevalence rate was 12.8 cases/10(5) inhabitants in 2012. Over the last two decades, there was a noted increase in the frequency of IBD in the study area. CONCLUSION: In this study, there was a predominance of patients with UC, young people under 40 years of age, individuals with racial miscegenation, and low annual incomes.

RESUMEN

Global concern in relation to child mortality gained visibility with the release of the Millennium Development Goals in 2000 in which the reduction of child mortality is included under goal number four, which proposes to reduce the mortality rate of children under five years by two thirds between 1990 and 2015. Reducing child mortality has been a major priority of social health policies of the Brazilian government. The identification of risk factors associated with infant mortality can assist in the planning of actions to restructure and improve care for pregnant women and newborns in order to reduce child mortality. With this in mind, this study sets out to analyze the use of the linkage method to identify risk factors associated with infant mortality. An integrative review of the literature was conducted for this purpose and eight complete articles published between 2008 and 2013 were analyzed using the following key words: infant mortality, risk factors and information systems. The use of the linkage method proved to be very useful, enabling adequate investigation of the factors most strongly related to child mortality, showing its relevance to the study of public health problems.
