Metal levels in waste pickers in Brasilia, Brazil: hair and nail as exposure matrices.

The aim of this cross-sectional study was to compare workplace conditions and metal exposures in 431 waste pickers who worked nearby at the Estrutural Dump in Brasilia utilizing hair (n = 310) and nail (n = 355) as matrices of exposure. Waste pickers were grouped according to their workplace (open waste dump: G1 and sorting plants: G2). Hair and nail samples were collected and analyzed using ICP-MS. The work duration in the facilities was significantly different between the groups with averages of 16.46 (8.48) yrs and 9.26 (6.28) yrs for hair donors in G1 and G2, and 15.92 (7.72) yrs and 8.55 (5.77) yrs for toenail donors in G1 and G2, respectively. The arithmetic means (µg/g) of cadmium, copper, lead, and manganese in hair were significantly higher in G2 (0.076 ± 0.133; 19.61 ± 18.16; 2.27 ± .56 and 3.87 ± 5.59, respectively) compared to G1 (0.069 ± 0.235; 15.72 ± 15.18; 1.72 ± 4.04 and 3.65 ± 5.5, respectively). Concentrations of arsenic, barium, cadmium, copper, cobalt, lead, manganese, and molybdenum in nail were significantly higher in G2 (0.57 ± 0.39; 22.74 ± 42.06; 0.1 ± 0.08; 22.7 ± 51.60; 0.48 ± 0.45; 4.69 ± 9.43; 19.07 ± 20.75; 1.80 ± 1.76, respectively) compared to G1 (0.40 ± 0.28; 15.32 ± 22.31; 0.08 ± 0.11; 11.91 ± 16.25; 0.37 ± 0.37; 3.94 ± 15.04; 13.01 ± 19.08; 1.16 ± 1.80, respective. Our findings suggest that the studied population was exposed to toxic metals and indicates the need for chemical exposure prevention policies to monitor chemical risk exposures in waste pickers.

A descriptive analysis of hospitalized adolescents facing chronic illnesses with different durations of disease.

OBJECTIVES: To assess characteristics of hospitalized adolescents facing chronic diseases, correlating the perceptions of their illness, quality of life and the prevalence of risk behaviors, considering gender and the diseases' durations. METHODS: The sample consisted of 61 adolescents, aged between 10 and 19 years, with chronic diseases, hospitalized at the University Hospital of the State University of Londrina. They answered a questionnaire and the scales World Health Organization Quality of Life (WHOQOL-BREF) and Illness Perception Questionnaire (IPQ). They were divided in groups, according to the durations of the disease: group 1 (up to 4 years) and group 2 (5 years or more). RESULTS: Group 2 demonstrated higher leisure activity (p = 0.02) and more painful symptoms (p = 0.02). In WHOQOL-BREF, group 2 had a higher quality of life in the domain on environment (p = 0.02) and a higher total score (p = 0.04). Lower scores on the IPQ were associated with higher scores on the WHOQOL-BREF. Positive correlation was found between WHOQOL-BREF total score and years of disease, in which male presented higher scores. CONCLUSIONS: These findings may alert to the need for more knowledge about the diseases and the importance of encouraging ways to improve quality of life and care to reduce risky behaviors.

Relationship between actinic keratosis and malignant skin lesions on the eyelid / Relação entre ceratose actínica e lesões cutâneas malignas na pálpebra

ABSTRACT Purpose: To evaluate the variables possibly related to actinic keratosis and malignant skin lesions on the eyelid. Methods: A prospective study of patients with suspected eyelid malignancy was conducted. The participants underwent a 2-mm punch biopsy at two opposite sites of the lesion for diagnosis, and the results were compared with those of the histopathological study of the surgical excised specimen. The patients with an actinic keratosis component were divided into two groups (actinic keratosis-associated malignancy and actinic keratosis alone), which were compared for the following variables: age, disease duration, largest diameter, tumor area, Fitzpatrick classification, sex, tumor site and margin involvement. A cluster analysis was also performed. Results: We analyzed 174 lesions, of which 50 had an actinic keratosis component. Actinic keratosis was associated with squamous cell carcinoma in 22% of the cases and to basal cell carcinoma in 38%, which shows that both neoplasms may have contiguous actinic keratosis. Statistical analysis revealed no significant difference among the variables. In a cluster analysis, four groups were identified with malignant lesions in the medial canthus with the largest mean diameter and area. All margin involvements on the lower eyelid were related to malignancy, which means that all cases with margin involvement had an almost 100% risk of malignancy. Conclusions: Larger actinic keratosis lesions in the medial canthus and lesions with margin involvement on the lower eyelid have a greater probability of malignant association.

RESUMO Objetivo: Avaliar as possíveis variáveis relacionadas à ceratose actínica e lesões malignas cutâneas nas pálpebras. Métodos: Estudo prospectivo de pacientes com lesões palpebrais suspeitas de malignidade. Os participantes foram submetidos à biopsia por trépano (punch) de 2-mm em dois pontos opostos da lesão como método diagnóstico e os resultados foram comparados com o estudo histopatológico da peça excisada cirurgicamente. Aqueles que apresentaram ceratose actínica como resultado foram divididos em dois grupos (ceratose actínica associada com malignidade e ceratose actínica isolada) e foram comparados de acordo com as variáveis: idade, tempo de doença, maior diâmetro, área do tumor, classificação de Fitzpatrick, gênero, localização e acometimento da margem palpebral. A análise de cluster também foi realizada. Resultados: Foram analisadas 174 lesões e 50 delas tinham ceratose actínica como componente do tumor. Ceratose actínica esteve associada ao Carcinoma Espinocelular em 22% dos casos e ao Carcinoma Basocelular em 38%, mostrando que ambos podem ter ceratose actínica adjacente. A análise estatística não encontrou diferença entre as variáveis. A análise de cluster identificou quatro grupos e mostrou que lesões malignas no canto medial tinham maiores diâmetro e área. Acometimento da margem na pálpebra inferior relacionou-se em 100% com malignidade, enquanto a ausência de acometimento da margem mostrou menor chance de malignidade. Conclusões: Lesões maiores de ceratose actínica no canto medial e lesões com acometimento da margem palpebral inferior têm maiores chances de associação com malignidade.

Cognitive impairment, childhood trauma, sedentary behaviour, and elevated C-reactive protein levels in major affective disorders.

Elevated C-reactive protein (CRP) levels were associated with cognitive decline, sedentary behaviour, and childhood trauma in patients with major affective disorders. This study aims to examine the association of peripheral CRP levels, cognitive function, childhood trauma, sedentary behaviour, and quality of life in individuals with major affective disorders, including bipolar disorder (BD), major depressive disorder (MDD), and individuals without mood disorders (controls). We included outpatients with BD (n = 42), MDD (n = 27), and healthy controls (n = 40). All participants were assessed by a questionnaire, structured clinical interview, and the following scales: international physical activity questionnaire, childhood trauma questionnaire, 17-item Hamilton Depression Rating Scale (HDRS17), and World Health Organization Quality of Life instrument, brief version (WHOQOL-BREF). Other measures were included: hs-CRP levels, anthropometric measures, and cognitive tests (Trail-making test part A and part B, Stroop test, phonemic verbal fluency test, and semantic verbal fluency test). Our results indicated that BD outpatients were less significantly physically active on leisure domain than controls. Levels of hs-CRP ≥ 5 mg/L were significantly linked with a history of childhood sexual abuse and childhood physical abuse, as well as worse neurocognitive performance in major depressive disorders, mainly in BD. There was a significant negative correlation between Trail-making part B score and WHOQOL-BREF total score. The findings support the hypothesis that levels of hs-CRP ≥ 5 mg/L may be a possible predictor of cognitive dysfunction, childhood sexual abuse and sedentary behaviour in major affective disorders.

Growth hormone directly favors hepatic ketogenesis in persons with prediabetes or type 2 diabetes mellitus treated with empagliflozin.

PURPOSE: Sodium-glucose cotransporter 2 inhibitors increase glucagon secretion by pancreatic alpha cells and the susceptibility to ketoacidosis. On the other hand, growth hormone (GH) stimulates peripheral lipolysis and provides free fatty acids (FFA) for ketogenesis; however, it remains unresolved whether GH directly impacts hepatic ketogenesis. We aimed to investigate the role of physiologic GH levels in promoting ketogenesis in prediabetic or type 2 diabetic patients under empagliflozin treatment. METHODS: Sixteen patients (11 women, 5 men) with prediabetes or type 2 diabetes mellitus, aged 55.6 ± 4.7 years and with a mean BMI of 30.7 ± 4.8 kg/m2 and HbA1c 7.1 ± 1.6% (means ± SD), participated in this study. All of them were submitted to three mixed-meal tests: they received placebo at -60 min (test 1), and empagliflozin 25 mg (test 2, 21st day) and empagliflozin 25 mg plus pegvisomant 30 mg were administered subcutaneously 36 h before (test 3, 28th day). After test 1, all patients were instructed to take empagliflozin 25 mg daily. RESULTS: The empagliflozin treatment decreased the plasma concentrations of glucose by 14% (P < 0.01), FFA by 23% (P < 0.01), and the insulin/glucagon ratio by 26% (P < 0.01), and it increased ß-hydroxybutyrate by 44% (P < 0.05). The GH receptor block by pegvisomant restored the plasma ß-hydroxybutyrate to baseline levels. CONCLUSIONS: We conclude that GH has a direct effect on promoting the ketogenesis environment in patients treated with empagliflozin.

Intensive care unit time and prolonged enucleation to processing interval are associated with donor cornea contamination.

PURPOSE: To determine donor cornea contamination rate and to determine factors associated with cornea contamination. To assess the effect of hospitalization, intensive care unit (ICU) time, and antibiotic use on corneal contamination rate. To determine the spectrum of the contaminating microorganisms. METHODS: The contamination rate of 212 corneas, obtained by enucleation from April 2014 to January 2015 in a single eye bank, was assessed retrospectively according to age, sex, cause of death, systemic antibiotic use, hospitalization time, ICU time, mechanical ventilation (MV), death to enucleation interval (DEI), enucleation to processing interval (EPI), and corneal epithelial exposure grading. The relative risk (RR) and adjusted RR with a 95% confidence interval were calculated using IBM-SPSS 20.0. RESULTS: The contamination rate was 35.6% (n = 75). On multivariate analysis, ICU stay of 4 days or longer and enucleation to processing interval (EPI) greater than 7.4 h (RR 1.58, CI 0.96-2.60, P = 0.06) were associated with donor cornea contamination. Corneal contamination risk was highest from 4 to 6 days at the ICU (RR 3.40, CI 1.54-7.51, P < 0.01) and decreased after 7 days (RR 2.22, CI 1.00-4.93, P = 0.05). Coagulase-negative Staphylococcus was the most common isolated bacteria (69.6%). The frequency of gentamicin-resistant bacteria was higher among patients who stayed 4 days or longer at the ICU. CONCLUSION: Patients staying at the intensive care unit 4 days or longer showed increased risk of corneal contamination. This is an important result to consider further indication for cornea donation.

Poor Relationships and Physical Violence at School Are Associated With More Forms of Psychological Violence Among Brazilian Teachers: A Cross-Sectional Study.

Our purpose was to identify individual and work-related factors that are associated with psychological violence (PV) and are related to a higher number of PV forms among teachers. This cross-sectional study included 789 elementary and high school teachers in a municipality in southern Brazil. Data were obtained through interviews and a self-administered questionnaire. PV was characterized by reports of insults from students, humiliation by colleagues or teachers, and threats in the 12 months preceding the study. Factors associated with the number of PV forms were also investigated. Poisson regression models were used for the analyses. More than half (64.1%) of the teachers reported at least one event of PV, 38.3% reported only one form, 21.5% reported two forms, and 4.3% reported all three surveyed forms. After adjustments, poor relationships with superiors or students and having suffered physical violence at school remained associated with at least one PV episode. The same variables were associated with the number of forms of PV, as were age (inverse relationship) and violence outside of school. The higher the number of aggregated factors, the more estimated forms of PV, particularly among the younger teachers. These results highlight the importance of adopting strategies that promote a nonviolent and safe school environment for teachers, which will in turn improve work conditions, the quality of education, and teachers' health.

The effect of water source and soil supplementation on parasite contamination in organic vegetable gardens.

The objective of this study was to determine factors associated with vegetable contamination with zoonotic protozoan. Samples of water, soil and vegetables were collected from July/2014 to May/2016, totaling 83 samples, 21 properties of Londrina region, Paraná, Brazil. DNA amplification of Toxoplasma gondii, Cryptosporidium spp. and Giardia intestinalis in the samples was conducted using polymerase chain reaction (PCR). The PCR results were positive for T. gondii in 12.9% (8/62), Cryptosporidium spp. in 11.3% (7/62) and G. intestinalis in 25.8% (16/62) of the samples. DNA sequencing identified C. parvum in five samples and G. intestinalis Assemblage E in three. The statistical associations demonstrated greater probability of positive samples for T. gondii and for at least one of the three protozoa when the source of irrigation water was the river; a greater chance of positive samples for Cryptosporidium spp. when deer were present on the property; and a smaller chance of positive samples for at least one of the three etiologic agents when soil was supplemented with limestone. The results expose some critical contamination points, providing support for training farmers on good management practices during the production process.

Effects of adjunctive N-acetylcysteine on depressive symptoms: Modulation by baseline high-sensitivity C-reactive protein.

Outcomes in a RCTs of 12 weeks of theclinical efficacy of N-acetylcysteine (NAC) as an adjunctive treatment on depression and anxiety symptoms and its effects on high-sensitivity C-reactive protein (hs-CRP) levels. A wide array of measures were made. The 17-item version of the Hamilton Depression Rating Scale (HDRS17); the Hamilton Anxiety Rating Scale (HAM-A); Sheehan Disability Scale; Quality of Life; Clinical Global Impression (CGI); anthropometrics measures; and vital signs and biochemical laboratory. There were no significant differences among the groups regarding demographic, clinical features, use of medication, metabolic syndrome and comorbidities. From baseline to week 12, individuals receiving NAC, versus placebo, had a statistically significant reduction in depressive symptoms on HDRS17 (p < 0.01) and anxiety symptoms on HAM-A (p = 0.04), but only for individuals with levels of hs-CRP > 3 mg/L at baseline. Individuals receiving NAC with baseline levels of hs-CRP > 3 mg/L, had more significant reduction in uric acid levels compared to individuals with baseline levels of hs-CRP ≤ 3 mg/L on week 12. Participants receiving placebogained significantly more weight during the 12 weeks for baseline levels of hs-CRP ≤ 3 mg/L and hs-CRP > 3 mg/L, and individuals receiving NAC in both groups did not have significant weight change during the 12 weeks. No individuals were withdrawn from the study because of adverse event. NAC group exhibited significantly greater reduction on hs-CRP levels than placebo group from baseline to week 12. TRIAL REGISTRATION: clinicaltrials.gov Identifier; NCT02252341.

Blood manganese levels and associated factors in a population-based study in Southern Brazil.

Manganese (Mn) is an essential dietary nutrient for human health serving as a cofactor for many enzymes; however, exposure to excessive quantities of Mn may lead to toxicity with symptoms analogous to Parkinson's disease (PD). Population-based biomonitoring is an effective tool for characterizing the body burden of environmental or occupational pollutants, including Mn. The objective of this cross-sectional study was to (1) estimate reference values (RV) for blood Mn in an adult population and (2) assess the variables that were associated with higher blood metal levels. A total of 947 adults, aged 40 years or older, were randomly selected in a city in Southern Brazil. Information on socioeconomic, dietary, lifestyle, and occupational background was collected by trained interviewers. Blood Mn levels (µg/L) were analyzed by inductively coupled plasma-mass spectrometer (ICP-MS). The RV for blood Mn concentrations were obtained from the upper limits of the 95% confidence intervals (CI) of the 95th percentile distributions. Cluster analysis was performed to identify variables associated with high or low blood Mn concentrations. The RV for blood Mn levels in this study were 18.54 and 20.15 µg/L for men and women, respectively. Mn blood concentrations decreased with age and were higher in females compared to males. No marked association was noted between blood Mn and smoking or drinking habits, education levels and socioeconomic status. Diastolic blood pressure was higher in a group of women approximately 54 years of age associated with elevated blood Mn levels. Important reference data stratified by demographic and lifestyle factors that may prove useful for future surveillance of environmental exposure to Mn and health risks associated with this metal are presented.

Association of lead, cadmium and mercury with paraoxonase 1 activity and malondialdehyde in a general population in Southern Brazil.

Metal exposure is associated with increased oxidative stress (OS), which is considered an underlying mechanism of metal-induced toxicity. Malondialdehyde (MDA) is a final product of lipid peroxidation, and it has been extensively used to evaluate metal-induced OS. Pro-oxidant effects produced by metals can be mitigated by paraoxonase 1 (PON1), an antioxidant enzyme known to prevent cardiovascular disease and atherosclerosis. Among other factors, the Q192R polymorphism and the exposure to heavy metals have been known to alter PON1 activity. Here, we evaluated the association of blood lead (Pb), cadmium (Cd) and mercury (Hg) levels with PON1 activity, and with MDA concentrations in a randomly selected sample of Brazilian adults aged 40 years or older, living in an urban area in Southern Brazil. A total of 889 subjects were evaluated for blood Pb and Cd levels, and 832 were tested for Hg. Geometric mean of blood Pb, Cd and Hg was 1.93µg/dL, 0.06µg/L and 1.40µg/L, respectively. PON1 activity was significantly different among various genotypes: QQ (PON1=121.4U/mL), QR (PON1=87.5U/mL), and RR (PON1=55.2U/mL), p<0.001. PON1 genotypes were associated only with Cd blood levels. Those with QR genotype had Cd concentrations higher (0.07µg/L) than those with the RR genotype (0.04µg/L) with p=0.034. However, PON1 activity was not significantly associated with metal concentrations. Cluster analysis showed that men who reported to be current smokers and drinkers with higher blood Pb and Cd levels, had significantly lower PON1 activity than non-smokers or -drinkers, and women with lower Pb and Cd levels. RR genotype carriers had lower PON1 activity than those with the QR genotype, and had higher levels of Pb and Cd compared with other genotype carriers. For blood Hg, no association with PON1 activity or genotype was noted. We found low levels of Pb, Cd and Hg in environmentally exposed Brazilian adults. Cd concentrations were increased in subjects with QR genotype. Those with RR genotype had lower PON1 activity and higher levels of Pb and Cd than other genotype carriers. The results of cluster analysis suggested that smoking status exerts a significant influence on PON1 activity. Other studies with environmentally exposed populations are required to further clarify whether low blood levels of metals influence OS biomarkers.

Association between blood lead and blood pressure: a population-based study in Brazilian adults.

BACKGROUND: Environmental lead exposure among adults may increase blood pressure and elevate the risk of hypertension. The availability of data on blood lead levels (BLL) in adult Brazilian population is scarce and population-based studies are important for screening the population exposure and also to evaluate associations with adverse health effects. The goal of this study was to examine the association of BLL with blood pressure and hypertension in a population-based study in a city in Southern Brazil. METHODS: A total of 948 adults, aged 40 years or older, were randomly selected. Information on socioeconomic, dietary, lifestyle and occupational background was obtained by orally administered household interviews. Systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured according to the guidelines VI Brazilian Guidelines on Hypertension. BLL were measured by inductively coupled plasma mass spectrometry technique. Multiple linear and logistic regression models were performed to evaluate associations of BLL with SBP and DBP, and with the chance of hypertension and of elevated SBP and DBP. RESULTS: The geometric mean of BLL was 1.97 µg/dL (95%CI:1.90-2.04 µg/dL). After multivariable adjustment, participants in the quartile 4 of blood lead presented 0.06 mm/Hg (95%CI, 0.04-0.09) average difference in DBP comparing with those in quartile 1. Participants in the 90th percentile of blood lead distribution had 0.07 mmHg (95% CI, 0.03 to 0.11) higher DBP compared with those participants in the 10th percentile of blood lead. The adjusted OR for hypertension was 2.54 (95% CI, 1.17-5.53), comparing the highest to the lowest blood lead quartiles. Compared with participants in the 10th percentile of blood lead, participants in the 90th percentile presented higher OR for hypertension (OR: 2.77; 95% CI, 1.41 to 5.46). CONCLUSION: At low concentrations, BLL were positively associated with DBP and with the odds for hypertension in adults aged 40 or older. It is important to enforce lead exposure monitoring and the enactment of regulatory laws to prevent lead contamination in urban settings.

A prospective study of treatment of carbapenem-resistant Enterobacteriaceae infections and risk factors associated with outcome.

BACKGROUND: To describe the clinical and microbiological data of carbapenem-resistant Enterobacteriaceae (CRE) infections, the treatment used, hospital- and infection-related mortality, and risk factors for death. METHODS: A prospective cohort conducted from March 2011 to December 2012. Clinical, demographic, and microbiological data such as in vitro sensitivity, clonality, carbapenemase gene mortality related to infection, and overall mortality were evaluated. Data were analyzed using Epi Info version 7.0 (CDC, Atlanta, GA, USA) and SPSS (Chicago, IL, USA). RESULTS: One hundred and twenty-seven patients were evaluated. Pneumonia, 52 (42 %), and urinary tract infections (UTI), 51 (40.2 %), were the most frequent sites of infection. The isolates were polyclonal; the Bla KPC gene was found in 75.6 % of isolates, and 27 % of isolates were resistant to colistin. Mortality related to infection was 34.6 %, and was higher among patients with pneumonia (61.4 %). Combination therapy was used in 98 (77.2 %), and monotherapy in 22.8 %; 96.5 % of them were UTI patients. Shock, age, and dialysis were independent risk factors for death. There was no difference in infection-related death comparing colistin-susceptible and colistin-resistant infections (p = 0.46); neither in survival rate comparing the use of combination therapy with two drugs or more than two drugs (p = 0.32). CONCLUSIONS: CRE infection mortality was higher among patients with pneumonia. Infections caused by colistin-resistant isolates did not increase mortality. The use of more than two drugs on combination therapy did not show a protective effect on outcome. The isolates were polyclonal, and the bla KPC gene was the only carbapenemase found. Shock, dialysis, and age over 60 years were independent risk factors for death.

Prevalência de fatores de risco de doença cardiovascular em trabalhadores de condomínios / Prevalence of cardiovascular disease risk factors among condominium workers

Contexto: As doenças cardiovasculares (DCV) representam a principal causa de morte no Brasil e existem poucos estudos que relacionam seus fatores de risco com trabalhadores de condomínios. Objetivos: Determinar a prevalência dos principais fatores de risco para as doenças cardiovasculares em trabalhadores de condomínios residenciais e comerciais e relacioná-los com seus enquadramentos funcionais. Métodos: Estudo epidemiológico transversal e observacional com 380 indivíduos selecionados aleatoriamente por enquadramento funcional: portaria, zeladoria, faxina e auxiliar de limpeza. Foi utilizado um formulário individual padronizado para coleta de dados após consulta médica em ambulatório de Medicina Geral, que atende 4.735 trabalhadores em Londrina (PR). Os fatores de risco para DCV analisados foram: idade, sexo, índice de massa corpórea, hipertensão arterial sistêmica (HAS), diabetes mellitus tipo 2 (DM2), pré-diabetes (pré-DM), hipercolesterolemia, evento cardiovascular prévio, sedentarismo e tabagismo. Resultados: A maioria dos trabalhadores era composta por homens, exercia a função na portaria e apresentava mais de 40 anos de idade. As prevalências encontradas foram: HAS ­ 39,5%; hiperglicemia (pré-diabetes e diabetes tipo 2) ­ 18,2%; hipercolesterolemia ­ 35,3%; tabagismo ­ 12,1%. Cabe ressaltar a elevada prevalência de excesso de peso encontrada em mais 80% da amostra estudada, sendo que quase metade se situava na faixa de obesidade. Além disso, o sedentarismo foi encontrado em 80% dos indivíduos pesquisados. Conclusão: A distribuição elevada dos fatores de risco de DCV entre os trabalhadores de condomínio deve estimular a adoção de estratégias para melhorar as condições de saúde desses trabalhadores. O maior conhecimento do perfil clínico-ocupacional de um grupo fornece subsídios para viabilizar o correto direcionamento de recursos nos programas de saúde, bem como aumenta a qualidade de vida no trabalho.

Context: Cardiovascular diseases (CVD) are the leading cause of death in Brazil and there are few studies that relate their risk factors with condominium workers. Objectives: To determine the prevalence of the major risk factors for CVD in residential and commercial condominium workers and relate them to their functional frameworks. Methods: Transversal and observational epidemiologic study with 380 individuals randomly selected by functional framework: reception desk, concierge, housekeeping and cleaning assistant. A standardized form was used to collect data after medical consultation in a general practice clinic responsible for 4.735 workers in Londrina, state of Paraná, Brazil. The following risk factors for CVD were analyzed: age, sex, body mass index, systemic arterial hypertension (SAH), type 2 diabetes (T2DM), pre-diabetes (IGT ­ impaired glucose tolerance), hypercholesterolemia, previous cardiovascular event, sedentary lifestyle and smoking. Results: Most of the workers were men, worked as doormen and had more than 40 years old. Prevalence rates were: SAH ­ 39,5%; hyperglycemia (type 2 diabetes and pre-diabetes) ­ 18,2%; hypercholesterolemia ­ 35,3%; smoking ­ 12,1%. A high prevalence of overweight was found in over 80% of the sample, with almost half belonging in the obesity range. Moreover, 80% of the individuals were sedentary. Conclusion: The high distribution of CVD risk factors among condominium workers should encourage the adoption of strategies to improve the health of them. Greater knowledge of the clinical and occupational profile of a group provides subsidies to enable the correct targeting of resources in health programs and increases the quality working life.

Is pilates as effective as conventional pelvic floor muscle exercises in the conservative treatment of post-prostatectomy urinary incontinence? A randomised controlled trial.

AIMS: To verify the efficacy of a Pilates exercise program compared to conventional pelvic floor muscle exercise (PFME) protocol in the conservative treatment of post-prostatectomy urinary incontinence (PPUI). METHODS: Baseline assessment was performed four weeks postoperatively and included 24 hr pad test, bladder diary, and the ICIQ-SF. Patients were randomised into three groups: Pilates (G1), PFME combined with anal electrical stimulation (G2), and a control group (G3). Both treatment groups had to perform 10 weekly treatment sessions. Primary outcomes were mean reduction of daily pads and mean reduction of ICIQ-SF score four months after surgery. The significance level was set at P < 0.05. RESULTS: 85 patients completed the study. Differences between treatment groups (G1 and G2) in terms of mean reduction in daily pad usage, 24 hr pad test, and ICIQ-SF scores were not statistically significant (P > 0.05). The control group differed from G1 in daily pad usage (P = 0.01) and ICIQ-SF score (P = 0.0073). Intergroup comparisons revealed that 57.7% of the volunteers in G1 and 50% of the individuals from G2 no longer used pads by the end of the treatment period (P = 0.57). In the control group, 22.6% were not using pads four months after surgery, with statistical difference compared to G1 (P < 0.05). CONCLUSIONS: The Pilates exercise program proved to be as effective as conventional PFME to speed up continence recovery in PPUI. It also achieved a higher rate of fully continent patients when compared to the control group in the short-term. Neurourol. Urodynam. 35:615-621, 2016. © 2015 Wiley Periodicals, Inc.

Effects of extra virgin olive oil and fish oil on lipid profile and oxidative stress in patients with metabolic syndrome.

OBJECTIVE: The aim of this study was to verify if extra virgin olive oil and fish oil have a synergistic effect on lipid and oxidative stress parameters in patients with metabolic syndrome (MetS). METHODS: This intervention study included 102 patients (81 women and 21 men) with MetS (mean age 51.45 ± 8.27 y) from the ambulatory center of the University Hospital of Londrina, Paraná, Brazil. Patients were randomly assigned to one of four groups: Patients in the control group (CG) were instructed to maintain their usual diet; the second group (fish oil group [FO]) received 3 g/d of fish oil ω-3 fatty acids (10 capsules); the third group (extra virgin olive oil group [OO]) received 10 mL/d of extra virgin olive oil at lunch and dinner; and the fourth group (fish oil and extra virgin olive oil group [FOO]) received 3 g/d of fish oil ω-3 fatty acids and 10 mL/d of extra virgin olive oil. MetS related markers and oxidative stress were measured at baseline and after 90 d. RESULTS: Differences across treatment groups showed a statistically significant decrease (P < 0.05) in total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) when FOO was compared with CG and OO, respectively. Hydroperoxides showed a significant decrease (P < 0.05) when FOO was compared with CG, whereas there was an increase in total peroxyl radical-trapping antioxidant potential/advanced oxidation protein products (TRAP/AOPP; P < 0.05) in FOO when compared with FO. In relation to baseline values, there was a significant decrease (P < 0.05) in LDL-C values, and TC/high-density lipoprotein cholesterol (HDL-C) and LDL-C/HDL-C indexes in FOO. There was also a decrease (P < 0.05) in hydroperoxides, in AOPP and in AOPP/TRAP index in FOO, and an increase (P < 0.05) in TRAP/AOPP index in FOO and in TRAP/uric acid ratio in OO. CONCLUSION: The present study provides evidence that increased dietary ω-3 polyunsaturated fatty acids and extra virgin olive oil have beneficial synergistic effects on lipid metabolism and oxidative stress in patients with MetS.

Risk factors for lead exposure in adult population in southern Brazil.

In Brazil there is no systematic evaluation to access blood lead levels (BLL) in the general population and few studies with adults have been published. The aim of this study was to examine the socioeconomic, environmental, and lifestyle determinants of BLL in the adult Brazilian population. In total, 959 adults, aged 40 years or more, were randomly selected in a city in southern Brazil. Information on socioeconomic, dietary, lifestyle, and occupational background was obtained by interviews. A spatial analysis was conducted to discern whether there were any identifiable sources of exposure. BLL were measured by inductively coupled plasma-mass spectrometry. There was an adjustment for gender, age, race, education, income class, smoking status, alcohol consumption, occupation, and red meat or cow milk consumption (Model 1), and for occupation and gender (Model 2). The geometric mean of BLL was 1.97 µg/dl (95% CI: 1.9-2.04 µg/dl). In Model 1, BLL were positively associated with male gender, older age, and drinking and smoking habits, and less frequently with milk consumption. In Model 2, data showed higher BLL in non-white than white participants, in former smokers and individuals with current or former employment in lead (Pb) industries. The participants living in the area with more Pb industries had higher BLL (3.3 µg/dl) compared with those residing in other areas with no or fewer Pb industries (1.95 µg/dl). Despite the low BLL found in adults living in an urban area, Pb industries need to be monitored and regulatory laws implemented to prevent metal contamination in urban settings.
