Distribution and availability of copper, iron, manganese and zinc in the archaeological black earth profile from the Amazon region

Os solos de terra preta arqueológica são ricos em matéria orgânica, contêm fragmentos cerâmicos e artefatos líticos e apresentam nutrientes em concentrações mais elevadas do que outros tipos de solos. Com o intuito de contribuir com informações sobre concentrações de micronutrientes disponíveis em solos de terra preta, foram avaliadas através de extrações químicas sequenciais, a distribuição e disponibilidade de Cu, Fe, Mn e Zn em um perfil de terra preta arqueológica no município de Juruti, estado do Pará. As maiores concentrações de Cu, Fe, Mn e Zn no perfil são encontradas na fração residual. Este estudo mostrou que ferro, manganês e zinco são preferencialmente disponíveis a partir das frações, associados aos óxidos de Fe-Mn, variando de 1265,39 a 1818,12 mg kg^-1, 0,83 a 48,51 mg kg^-1 e 1,92 a 12,05 mg kg^-1, respectivamente, e o cobre a partir da matéria orgânica, variando de 0,13 a 0,45 mg kg^-1.

Clinical, epidemiological, and therapeutic profile of dermatophytosis

BACKGROUND: The cutaneous mycoses, mainly caused by dermatophyte fungi, are among the most common fungal infections worldwide. It is estimated that 10% to 15% of the population will be infected by a dermatophyte at some point in their lives, thus making this a group of diseases with great public health importance. OBJECTIVE: To analyze the clinical, epidemiological, and therapeutic profile of dermatophytosis in patients enrolled at the Dermatology service of Universidade do Estado do Pará, Brazil, from July 2010 to September 2012. METHOD: A total of 145 medical records of patients diagnosed with dermatophytosis were surveyed. Data were collected and subsequently recorded according to a protocol developed by the researchers. This protocol consisted of information regarding epidemiological and clinical aspects of the disease and the therapy employed. RESULTS: The main clinical form of dermatophyte infection was onychomycosis, followed by tinea corporis, tinea pedis, and tinea capitis. Furthermore, the female population and the age group of 51 to 60 years were the most affected. Regarding therapy, there was a preference for treatments that combine topical and systemic drugs, and the most widely used drugs were fluconazole (systemic) and ciclopirox olamine (topical). CONCLUSION: This study showed the importance of recurrent analysis of the epidemiological profile of dermatophytosis to enable correct therapeutic and preventive management of these conditions, which have significant clinical consequences, with chronic, difficult-totreat lesions that can decrease patient quality of life and cause disfigurement.

Improvement of friable callus production of Boerhaavia paniculata Rich and the investigation of its lipid profile by GC/MS

Neste estudo, um protocolo para induzir maiores quantidades de calos friáveis de Boerhaavia paniculata RICH e uma técnica de lipidômica foram aplicados para investigar o perfil dos lipídios e serem comparados com aqueles presentes nas raízes desta planta, os quais apresentaram atividade anti-inflamatória no extrato hexânico bruto. A cultura de calo foi induzida a partir de sementes em meio sólido contendo sais de Murashige e Skoog com diferentes quantidades de glicose e diferentes concentrações de ácido 2,4-diclorofenoxiacético. Os frascos foram mantidos em câmara de germinação a 30 ± 2°C, com fotoperíodo de 16h sob intensidade luminosa de 27 µmol m^–2 s^–1 durante 4 semanas. Os melhores resultados para a formação de calo friável e desenvolvimento da biomassa foram obtidos no tratamento contendo 2,26 µM de 2,4-D e de glicose (1,5 %; m/v). Técnica de lipidômica foi aplicada na fração hexânica mostrando as concentrações mais elevadas de esteróides β-sitosterol (3,53 mg/100 g de cs - células seca ), e ácidos graxos; especialmente o ácido 2-hidroxi-tetracosanóico (0,34 mg/100 g cs), ácido eicosanoico (86,25 mg/100 g cs), ácido esteárico (420,83 mg/100 g cs), ácido tetradecanóico (10,74 mg/100 g cs) e ácido linoléico (100,61 mg/100 g cs). O perfil lipídico do calo versus aquele encontrado nas raízes da planta silvestre é descrito neste trabalho.

Lipid profile and cardiovascular risk in two Amazonian populations

OBJETIVO: Comparar o perfil lipídico e risco coronariano de uma população ribeirinha (Vigia) ao de uma população urbana (Belém). MÉTODOS: Foram avaliados 50 indivíduos de cada região, controlados por idade e sexo, examinando-se os principais fatores de risco para a doença coronariana. RESULTADOS: Segundo o Programa Nacional de Educação sobre o Colesterol (NCEP III) e determinando-se o escore de Framingham, ambas as populações expressaram o mesmo risco absoluto de eventos (Vigia 5,4 ± 1 vs. Belém 5,7 ± 1), a despeito da população de Vigia apresentar menor consumo de gordura saturada (p<0,0001), maior de mono e poliinsaturada (p<0,03), além de menores valores do índice de massa corpórea (25,4±0,6 vs. 27,6±0,7kg/m², p<0,02), da prega biceptal (18,6±1,1 vs. 27,5±1,3mm, p<0,0001) e triceptal (28,7±1,2 vs. 37,3±1,7mm, p<0,002), de colesterol total (205±5 vs. 223±6mg/dL, p< 0,03) e triglicérides (119 ± 9 vs. 177±18mg/dL, p<0,005), não diferindo no HDL-c (46±1 vs. 46±1mg/dL), LDL-c (135 ± 4 vs. 144 ± 5mg/dL) e pressão arterial (PAS 124 ± 3 vs. 128 ± 3mmHg; PAD 80 ± 2 vs. 82 ± 2mmHg). CONCLUSÃO: A população ribeirinha e urbana da Amazônia apresentaram risco cardiovascular semelhante. Entretanto, a marcante diferença entre as variáveis estudadas sugere que devam ser aplicadas diferentes estratégias de prevenção.

Profile of micronucleus frequencies and nuclear abnormalities in different species of electric fishes (Gymnotiformes) from the Eastern Amazon

The frequency of spontaneous micronucleus (MN) formation in fish species needs to be determined to evaluate their usefulness for genotoxic biomonitoring. The definition of a good bioindicator takes into account the current knowledge of its metabolic traits as well as other factors including its feeding behavior and relationship to the environment. In this study, we compared the basal frequencies of micronucleated erythrocytes and nuclear abnormalities (NA) among different species of the fish Order Gymnotiformes (Rhamphichthys marmoratus, Steatogenys elegans, Sternopygus macrurus, Parapteronotus hasemani, Gymnotus mamiraua, Gymnotus arapaima, Brachyhypopomus beebei, Brachyhypopomus n. sp. BENN) sampled in several localities of the Eastern Amazon. A baseline of MN and NA frequency in these fish was determined, enabling the identification of potentially useful species as models for genotoxicity studies. Only one impacted sample collected at a site in the River Caripetuba showed a significant number of NAs, which may be due to the release of wastewater by neighbouring mining industries and by the burnt fuel released by the small boats used by a local community. Our results may provide support for further studies in areas of the Eastern Amazon affected by mining, deforestation and other anthropogenic activities.

Association between phase angle, anthropometric measurements, and lipid profile in HCV-infected patients

OBJECTIVE: The objective of this study was to investigate the associations between phase angle, anthropometric measurements, and lipid profile in patients chronically infected with the hepatitis C virus. METHODS: A total of 160 consecutive patients chronically infected with the hepatitis C virus and who received treatment at the hepatitis C outpatient unit of our hospital from April 2010 to May 2011 were prospectively evaluated. Bioelectrical impedance analysis, anthropometric measurements, and serum lipid profile analysis were performed. RESULTS: Twenty-five patients were excluded. A total of 135 patients with a mean age of 49.8±11.4 years were studied. Among these patients, 60% were male. The phase angle and BMI means were 6.5±0.8° and 26.5±4.8 kg/m2, respectively. Regarding anthropometric variables, mid-arm circumference, mid-arm muscle circumference, and arm muscle area had a positive correlation with phase angle. In contrast, when analyzing the lipid profile, only HDL was inversely correlated with phase angle. However, in multiple regression models adjusted for age and gender, only mid-arm circumference (p = 0.005), mid-arm muscle circumference (p = 0.003), and arm muscle circumference (p = 0.001) were associated with phase angle in hepatitis C virus-infected patients. CONCLUSIONS: In conclusion, phase angle is positively correlated with anthropometric measures in our study. However, there is no association between phase angle and lipid profile in these patients. Our results suggest that phase angle is related to lean body mass in patients chronically infected with hepatitis C virus.

Anatomical changes and audiological profile in branchio-oto-renal syndrome: a literature review

Introduction  Branchio-oto-renal (BOR) syndrome is an autosomal-dominant genetic condition with high penetrance and variable expressivity, with an estimated prevalence of 1 in 40,000. Approximately 40% of the patients with the syndrome have mutations in the gene EYA1, located at chromosomal region 8q13.3, and 5% have mutations in the gene SIX5 in chromosome region 19q13. The phenotype of this syndrome is characterized by preauricular fistulas; structural malformations of the external, middle, and inner ears; branchial fistulas; renal disorders; cleft palate; and variable type and degree of hearing loss. Aim  Hearing loss is part of BOR syndrome phenotype. The aim of this study was to present a literature review on the anatomical aspects and audiological profile of BOR syndrome. Data Synthesis  Thirty-four studies were selected for analysis. Some aspects when specifying the phenotype of BOR syndrome are controversial, especially those issues related to the audiological profile in which there was variability on auditory standard, hearing loss progression, and type and degree of the hearing loss. Mixed loss was the most common type of hearing loss among the studies; however, there was no consensus among studies regarding the degree of the hearing loss.

Quality of life profile and correlated factors in chronic leg ulcer patients in the mid-west of São Paulo State, Brazil

BACKGROUND: Chronic leg ulcer may have an impact on patients' quality of life.OBJECTIVES:This study aimed to identify the impact of leg ulcers on patient's quality of life using the Dermatology Life Quality Index and to define the main factors correlated with this perception.METHOD:Cross-sectional, non-probabilistic sampling study. We included patients with chronic leg ulcers being treated for at least 3 months. A sociodemographic and clinical survey was conducted to assess the profile of the ulcers. We administered a screening for depressive symptoms and the Dermatology Life Quality Index. We performed a descriptive statistical analysis, chi-square test and Mann-Whitney test for categorical data, Pearson for numeric variables, and multiple regression for categorical data.RESULTS:Forty-one patients were assessed. Their mean age was 61.78 years. Venous ulcers (48.8%) were the most prevalent. Seventy-three percent of the sample perceived no impact/low impact on quality of life in the past week, and 26.8% perceived moderate/high impact. A multiple regression analysis identified the causes of lesion, pain related to the ulcers, time of onset, and severity of the depressive symptoms as the variables that had an influence on quality of life.CONCLUSIONS:The majority of the sample perceived low or no impact of the condition on the quality of the life. The variables etiology of the lesion (p<0.001), pain related to the ulcers (p=0.001), time of onset (p=0.006), and severity of the depressive symptoms (p<0.001) had an influence on the quality of life, suggesting the need for further studies with more robust designs to confirm the causal relationship between these characteristics and quality of life.
