OBJECTIVE:

The American Academy of Pediatrics recommends intramuscular (IM) vitamin K prophylaxis for all newborns to prevent vitamin K deficiency bleeding. Given the serious implications of late-onset vitamin K deficiency bleeding, our objective was to examine factors influencing parents’ decisions to refuse IM vitamin K prophylaxis.

METHODS:

Parents intending to refuse IM vitamin K prophylaxis at delivery were recruited from 5 community hospitals, 1 academic medical center, and 2 birthing centers in a single Southeastern state. Participants completed a written survey including demographics, birth and parenting decisions (eg, breastfeeding), and open-ended questions about their vitamin K information sources, concerns, and knowledge of risks.

RESULTS:

The incidence of refusal was highest at the birthing centers. Fifty-four parents intending to refuse IM vitamin K completed the survey. Most were white (78%), over age 30 (57%), and college graduates (65%). All reported intention to exclusively breastfeed. Most refused hepatitis B vaccine (90%) and erythromycin eye ointment (77%). The most common source of information was the Internet (70%). Concerns included synthetic or toxic ingredients (37%), excessive dose (28%), and side effects (24%). Eighty-three percent of parents reported awareness of risks associated with vitamin K refusal. However, only 6 parents (11%) decided to accept IM prophylaxis.

CONCLUSIONS:

This study provides an understanding of the concerns, mindset, and information sources used by parents refusing IM vitamin K. Educating parents about the importance of IM prophylaxis should begin in the prenatal period and must address concerns parents identify on the Internet.

Published: January 2016

OBJECTIVE:

Achieving high-value health care is a goal of health care providers who strive to increase quality and decrease cost. Decreasing laboratory tests is a potential method to increase value. We used quality improvement methodology to decrease the percentage of unnecessary complete blood counts (CBCs) and basic metabolic panels (BMPs) obtained on a pediatric hospital medicine service from 13.5% to <5%.

METHODS:

A pre- and postintervention design was conducted including all patients admitted to 2 hospital medicine teams between May 2013 and December 2014. Multiple interventions linked to key drivers were tested through rapid plan-do-study-act cycles. Primary and secondary outcome measures, percent reduction of unnecessary CBCs and BMPs, and consecutive day tests were analyzed using statistical process control. Total billed charges, laboratory charges, 7-day readmission rates, and length of stay were compared pre- and postintervention.

RESULTS:

Primary outcome of unnecessary CBCs and BMPs was reduced from a baseline of 13.5% to 4.5%. Secondary outcome measure of consecutive day testing was reduced from 20.9% to 8.5%. Median laboratory charges decreased significantly ($842 [$256–$1863] vs $800 [$222–$1616], P = .002), with no significant differences in total billed charges, 7-day readmission rates, or length of stay.

CONCLUSIONS:

Rapid cycle plan-do-study-act methodology, initially focusing on the inclusion of a daily laboratory plan in progress notes, was an effective means to improve laboratory utilization and decrease laboratory charges without adversely affecting other quality measures. Spreading these efforts to different patient populations and laboratory tests could have a demonstrable effect on the value of health care.

Authors: El Hassani Aziz
Published: January 2016

This paper, part of which was presented at the 12th annual AMICAL conference at the American University in Bulgaria held in Blagoevgrad, on 29 May 2015, reports on a doctoral research project which explores the meaning and role of information literacy in higher education and lifelong learning. It also highlights an information literacy initiative at a Moroccan university, namely Al Akhawayn University in Ifrane, and how its academic library strives to promote it. Living in an age of information tsunami and technological advancement, issues of information access, evaluation, retrieval and effective use, have become significantly critical in our societies. Directing the attention to the issue of information literacy and framing the best practices on how they can be best blended into the learning process of students are of paramount importance. Like other libraries across the globe, Mohammed VI Library at Al Akhawayn University in Morocco has realized the importance of information literacy and has worked in various ways to address this issue. This paper will describe the university strategy of teaching Information Literacy to graduate and undergraduate students in a number of ways. Recommendations to improve and support this initiative, including incorporating information literacy and skills across the university's curriculum, and fostering more effective partnerships between the Al Akhawayn university library and the teaching faculty, will be also discussed in this paper.

Published: January 2016

Resumo A aderência dos pacientes ao tratamento em hemodiálise é importante para o sucesso do tratamento, mas há carência de instrumentos de avaliação validados para o Brasil. Esta pesquisa visou à adaptação transcultural para o Brasil das escalas Renal Adherence Behaviour Questionnaire (RABQ) e Renal Adherence Attitudes Questionnaire (RAAQ), que avaliam os comportamentos e atitudes de aderência. Esses instrumentos foram submetidos aos procedimentos de adaptação transcultural: tradução, retradução, avaliação por comissão de especialistas e estudo piloto. Foram feitas modificações na redação dos itens e no formato de aplicação, que deve ser em entrevista face a face. Não foi necessário alterar as alternativas de respostas. As versões brasileiras das escalas RABQ e RAAQ apresentam equivalência semântica e cultural com as versões originais e foram redigidas de forma a facilitar sua compreensão pela população-alvo. As duas escalas necessitam ser submetidas a estudos de validade e fidedignidade para serem utilizadas.

Published: January 2016

Abstract This work reports the process and costs of comprehensively implementing two tests to decentralize the diagnosis of visceral leishmaniasis (VL) in an endemic city in Brazil: a rapid test (IT LEISH) and a direct agglutination test (DAT-LPC). The implementation began by training health professionals to perform the tests. Estimation of the training costs considered the proportional remuneration of all professionals involved and the direct costs of the tests used for training. The study was conducted between November 2011 and November 2013. During that time, 17 training sessions were held, and 175 professionals were trained. The training cost for each professional was US$ 7.13 for the IT LEISH and US$ 9.93 for the DAT-LPC. The direct costs of the IT LEISH and DAT-LPC were estimated to be US$ 6.62 and US$ 5.44, respectively. This first evaluation of the implementation of these diagnostic tests indicates the feasibility of decentralizing both methods to extend access to VL diagnosis in Brazil.

Published: January 2016

Abstract This study reviewed the evidence that assessed the association between maternal pre-pregnancy body mass index (BMI) and/or gestational weight gain and offspring body composition in childhood. A systematic review was conducted. Cohort studies, case-control studies and randomized controlled trials measuring offspring body composition by indirect methods were included. Meta-analyses of the effect of pre-pregnancy BMI on offspring fat-free mass, body fat percent, and fat mass were conducted through random-effects models. 20 studies were included, most of which reported a positive association of pre-pregnancy BMI with offspring body fat. Standardized mean differences in body fat percent, fat mass and fat-free mass between infants of women with normal pre-pregnancy BMI and those of overweight/obese women were 0.31 percent points (95%CI: 0.19; 0.42), 0.38kg (95%CI: 0.26; 0.50), and 0.18kg (95%CI: -0.07; 0.42), respectively. Evidence so far suggests that pre-pregnancy maternal overweight is associated with higher offspring adiposity.

Authors: Pinheiro Hudson Azevedo , Vilaça Karla Helena Coelho , Carvalho Gustavo de Azevedo
Published: January 2016

Abstract Objective : To assess muscle mass, risk of falls and fear of falling in elderly adults with diabetic neuropathy (DNP). Methods : 50 elderly patients with diabetes mellitus (DM) and diabetic neuropathy (NPD) participated in this study. Risk of falling was assessed using the Berg Balance Scale (BBS). Fear of falling was assessed by means of the Falls Efficacy Scale-International (FES-I). Muscle mass was assessed by tetrapolar bioimpedance analysis (BIA) and Janssen's equation. Subjects were divided into two groups: one with a history of falls in the six months before study enrollment (G1) and the other without history of falls (G2). Results : There were statistically significant differences between G1 and G2 regarding lean body mass (p < 0.05), risk of falls as measured by the BBS (p < 0.01), and fear of falling as measured by the FES-I (p < 0.01). In addition, there was a significant correlation between the BBS and BIA (r = 0.45 and p < 0.01), showing that the greater the lean body mass, the lower the risk of falling. Conclusions : We found an association between lean mass, risk of falls and fear of falling in elderly adults with DNP and a history of falls from own height.

Abstract Objective : To evaluate the prevalence of back pain, disability, and postural changes in the spines of adults of different ages and with different levels of body mass index (BMI). Methodology : A total of 534 users of the Brazilian Public Health System in Porto Alegre, Brazil, were included in the study. An evaluation of the thoracic and lumbar spine was performed using the Flexicurve instrument. Data was analyzed using descriptive statistics and the calculation of prevalence ratios (PR) and their respective confidence intervals of 95% (CI 95%). Three analyses were performed with the dependent variables pain, functional disability, and posture. Results : A significant association between pain and female gender (p = 0.000), and pain and change in the lumbar spine (p = 0.014) were found. The variable disability was associated with BMI (p = 0.004) and age (p = 0.001). When we analyzed postural change, an association was found only with age group (p = 0.032). Conclusion : These findings highlight the need for prevention and primary care educational programs aimed at reducing postural aberrations in the adult population.

Published: January 2016

The purpose of this study was to determine the accuracy of autofluorescence techniques for diagnosing oral mucosa lesions, using as reference pattern for comparison the visual diagnosis made by a clinical specialist. A pilot study was conducted with 60 patients divided in a control group without mucosal pathology and a study group with known clinical history for mucosal pathology. Both groups were examined by an oral medicine specialist and by a general dentist who used VELscope(r) system, which applies tissue fluorescence visualization to identify oral mucosal abnormalities. Using the VELscope(r) system, the general dentist made overdiagnosis in two cases and underdiagnosis in one case. The sensitivity and specificity for the oral medicine specialist were 1 (95% CI: 0.884 to 1). For the general dentist, the sensitivity did not improve significantly with the use of VELscope(r) system [0.53 (95% CI: 0.343 to 0.717) versus 0.49 (95% CI: 0.406 to 0.773)] and the specificity was 0.80 (95% CI: 0.614 to 0.923). A limitation of the study is the small sample size, which does not fully represent a population and extrapolation of the data should be done carefully. Based on the obtained results, no clinical benefits were obtained using this VELscope(r) system.

Published: January 2016

This research evaluated the influence of temporary cements (eugenol-containing [EC] or eugenol-free [EF]) on the tensile strength of Ni-Cr copings fixed with self-adhesive resin cement to the metal coronal substrate. Thirty-six temporary crowns were divided into 4 groups (n=9) according to the temporary cements: Provy, Dentsply (eugenol-containing), Temp Cem, Vigodent (eugenol-containing), RelyX Temp NE, 3M ESPE (eugenol-free) and Temp Bond NE, Kerr Corp (eugenol-free). After 24 h of temporary cementation, tensile strength tests were performed in a universal testing machine at a crosshead speed of 0.5 mm/min and 1 kN (100 kgf) load cell. Afterwards, the cast metal cores were cleaned by scraping with curettes and air jet. Thirty-six Ni-Cr copings were cemented to the cast metal cores with self-adhesive resin cement (RelyX U200, 3M ESPE). Tensile strength tests were performed again. In the temporary cementation, Temp Bond NE (12.91±2.54) and Temp Cem (12.22±2.96) presented the highest values of tensile strength and were statistically similar to each other (p>0.05). Statistically significant difference (p<0.05) was observed only between Provy (164.44±31.23) and Temp Bond NE (88.48±21.83) after cementation of Ni-Cr copings with self-adhesive resin cement. In addition, Temp Cem (120.68±48.27) and RelyX Temp NE (103.04±26.09) showed intermediate tensile strength values. In conclusion, the Provy eugenol-containing temporary cement was associated with the highest bond strength among the resin cements when Ni-Cr copings were cemented to cast metal cores. However, the eugenol cannot be considered a determining factor in increased bond strength, since the other tested cements (1 eugenol-containing and 2 eugenol-free) were similar.

Published: January 2016

Studies based on dentists' clinical practice possess vital relevance to understand factors leading the clinicians to choose by a specific technique over another. This study investigated which clinical conduct therapies are adopted by dentists in front of deep caries. Was evaluated how the place of work, post-graduate training and years since complete graduation influenced their decisions. A cross-sectional study was performed using a self-applied questionnaire with dentists (n=276) in Southern Brazil. Information regarding post-graduation training (specialization, master's or PhD), clinical experience (years since completing graduation) and place of work were investigated. The information regarding pulp vital therapies (materials for direct pulp capping; techniques for caries removal in deep cavities and strategies for indirect pulp capping) were collected by specific questions. Data were submitted to descriptive analysis and Exact Fischer Test. Response rate was 68% (187). The majority of dentists selected the calcium hydroxide (CH) as first material for direct (86.3%) and indirect (80.3%) pulp protection. Partial caries removal was reported by 61.9% of dentists. Less experienced clinical dentists choose partial caries removal more frequently (p=0.009), if compared with dentists graduated 10 years and up ago. The use of MTA was more common among professionals working at academic environment. Besides, MTA was not mentioned by professionals working exclusively in the public health service (p=0.003). In conclusion, the time since graduation influenced the clinical conduct related to caries removal. The choice of liner materials was influenced by dentists' workplace.

Published: January 2016

The aim of this study was to analyze the transplant efficiency of non-pedicled buccal fat pad graft (BFPG) for the treatment of Miller Class I or II gingival recessions (GRs) and to compare these results with those of subepithelial connective tissue graft (SCTG), which is considered the gold standard. Twelve patients with Miller Class I or II (≥2 mm) bilateral recessions in maxillary premolars or canines were selected. Recessions were randomly assigned to receive SCTG or BFPG. The clinical parameters evaluated at baseline and at 1, 3, and 6 months postoperatively included gingival index, plaque index, probing depth, GR, clinical attachment level, width of keratinized tissue, thickness of keratinized tissue and gingival margin to the acrylic guide. None of the evaluated clinical parameters differed significantly between the groups. At all evaluated postoperative time-points, both groups exhibited statistically significant differences in GR and gingival margin to the acrylic guide compared to baseline. Six months after surgery, the mean percentages of root coverage were 67.5% and 87.5% in the BFPG and SCTG groups respectively. In both groups, complete root coverage was observed in 50% of cases 6 months after surgery. The results presented herein indicate that the use of BFPG transplant has clinical similarities with SCTG and both may be considered as clinically successful methods for treating Miller Class I and II GRs.

Published: January 2016

The present study evaluated the reliability of FEA on the results of different mechanical properties (E and v) of materials. Two 3D models of a maxillary canine with endodontic treatment, intracanal post, composite resin core and restored with porcelain-fused-to-metal crown were generated according to micro-CT images. Two groups with different E and ν values for porcelain, metal coping alloy, resin cement and composite resin were established. The materials' properties for group GL were based on literature data, while for group GIE the impulse excitation technique was used. A load of 180 N was applied at 45° on the incisal third of the lingual surface of the canine tooth. All models were supported by the periodontal ligament (x=y=z=0). The von Mises stress (VMS) was calculated. The stress values revealed differences between the groups for both VMS distribution and value. The porcelain (GL: 5.966 MPa; GIE: 7.478 MPa), metal coping (GL: 3.811 MPa; GIE: 0.973 MPa) and core (GL: 4.771 MPa; GIE: 0.026 MPa) were significantly affected. In conclusion, this study showed that the determination of mechanical properties (E and ν) of materials is essential for the reliability on the results of FEA.

ABSTRACT: Aluminum (Al) is highly toxic to plants, causing stress and inhibiting growth and silicon (Si) is considered beneficial for plants. This chemical element has a high affinity with Al. The aim of this study was to investigate the potential of Si to mitigate the toxic effects of Al on potato ( Solanum tuberosum L.) plants and assess whether this behavior is different among genotypes with differing degrees of sensitivity to Al. Potato plants of the genotypes SMIJ319-7 (Al-sensitive) and SMIF212-3 (Al-tolerant) were grown for fourteen days in nutrient solution (without P and pH 4.5±0.1) under exposure to combinations of Al (0 and 1.85mM) and Si (0, 0.5 and 1.0mM). After this period, shoot and roots of the two genotypes were collected to determine Al content in tissues and assess morphological parameters of root and shoot growth. Roots of both genotypes accumulated more Al than shoots and the Al-tolerant genotype accumulated more Al than the sensitive one, both in roots and in shoot. Furthermore, the presence of 0.5 and 1.0mM Si together with Al reduced the Al content in shoot in both genotypes and in roots of the Al-tolerant genotype, respectively. Si ameliorated the toxic effects of Al with regard to number of root branches and leaf number in both potato genotypes. Si has the potential to mitigate the toxic effects of Al in potato plants regardless of Al sensitivity.

RESUMO: O objetivo deste trabalho foi estimar o tamanho de amostra para medir a densidade populacional de espécies de percevejos, variando métodos de coleta, altitude e cultivares de soja. Foram utilizadas 100 lavouras de soja, distribuídas em nove municípios da região central do Rio Grande do Sul, em três safras agrícolas (2010/2011, 2011/2012, 2012/2013). Em cada lavoura, foram demarcados 30 pontos distantes em 20 metros entre si. Em cada ponto, foram coletados percevejos (adultos + ninfas) das espécies Dichelops sp., Piezodorus guildinii e Euchistus heros, por meio dos métodos pano-de-batida largo e rede entomológica, totalizando 6.000 coletas. Para cada lavoura, método de coleta e espéciede percevejo, foram estimadas a média da densidade populacional e o tamanho de amostra por meio de reamostragem. O tamanho de amostra (número de pontos) para determinar a densidade populacional de percevejos varia com o método de coleta e a densidade populacional. Usando o pano-de-batida largo para a coleta de percevejos em soja, para um erro de estimação (amplitude do intervalo de credibilidade) igual a dois percevejos e densidade populacional na classe de 1,5 a 2,0 percevejos m-2, o tamanho de amostra é 13, 77 e 15, respectivamente, para as espécies Dichelops sp., P. guildinii e E. heros.
Histamina e rastreamento de pescado: revisão de literatura

Published: January 2016

A preocupação com a qualidade do pescado sempre foi um tema recorrente, visto que é um alimento de alto valor nutricional para toda população, porém com grande susceptibilidade à deterioração e formação de substâncias prejudiciais ao homem, caso não sejam obedecidas as condições de conservação. Um exemplo de substância formada é a histamina, uma diamina biogênica primária e heterocíclica, não volátil, termoestável, originada pela descarboxilação da L-histidina, quando as condições de manuseio e estocagem são inadequadas, favorecendo a multiplicação da microbiota natural do pescado. A histamina possui potencial alergênico, podendo causar um quadro de intoxicação no ser humano e, em casos graves, levar à morte. Para tal problema, um sistema de rastreabilidade poderia ser a solução. Seu objetivo é garantir ao consumidor um produto seguro e saudável por meio do controle de todas as fases da produção, industrialização, distribuição e comercialização, possibilitando uma perfeita correlação entre o produto final e a matéria-prima que lhe deu origem. Em diversos países existem atualmente sistemas de rastreabilidade controlando a cadeia de pescado. No Brasil, vários entraves podem ser apontados para a não obrigatoriedade da rastreabilidade em pescado. A divisão de regulamentação do setor entre diferentes órgãos, tais como Ministério da Pesca e Aquicultura (MPA), Ministério da Agricultura, Pecuária e Abastecimento (MAPA) e a Agência Nacional de Vigilância Sanitária (ANVISA), a falta de articulação entre esses órgãos fiscalizadores, a baixa capacitação de mão de obra e a desvalorização dos produtos da pesca, o que trazem a descapitalização da base da cadeia produtiva. De tal maneira, pode-se afirmar que há uma série de desafios para que ocorra a implantação de um sistema de rastreabilidade em território nacional. De acordo com o exposto, este estudo objetivou, através de uma revisão bibliográfica sistemática da literatura, informar a situação atual da escombrotoxicose e da rastreabilidade da histamina em pescado.
O produtivismo na era do "publique, apareça ou pereça": um equilíbrio difícil e necessário
Authors: Zuin Antônio A. S. , Bianchetti Lucídio
Published: January 2016

Na sociedade da cultura digital, um novo imperativo categórico impõe-se: ser significa ser midiática e eletronicamente percebido. Em conformidade com a lógica dessa nova ontologia, também o produtivismo acadêmico metamorfoseia-se numa espécie de produtivismo midiático e performático, na medida em que os artigos e seus respectivos autores se transformam em logotipos de sucesso quando são mais visualizados no ambiente virtual do que outros. Dado esse cenário e tendo como mediações pesquisas anteriores e revisão bibliográfica, objetiva-se, neste artigo, investigar o modo como a expressão "publique ou pereça" se converte em "publique, apareça ou pereça". Conclui-se que se faz cada vez mais necessário engendrar novas políticas de produção acadêmica, de tal maneira que seus autores reflitam criticamente sobre os conceitos de produtivismo, plágio, autoplágio e redundância no contexto da cultura digital.

Authors: LOPES Luísa Bandeira Pires Monteiro , ARAÚJO Andreia Sofia Lopes de , MILAGRE Virginia Barreiros
Published: January 2016

Objective: To quantify the color variation of two glass ionomer cements and a composite resin used in pediatric dentistry, after being immersed in different pigments agents. Methods: Using two glass ionomer cements (Ketac(tm) Molar and Photac(tm) Fil) and a microhybrid composite resin (Filtek(tm) z250), were produced 40 disks of each material (10 mm in diameter and 2 mm thick). The samples were soaked in artificial saliva (control group), coke, peach Ice Tea(r) and chocolate milk, for 72 hours in an oven at 37ºC. After this period, the samples were washed in 50 ml of distilled water. Finally, using the spectrophotometer, it was made the reading of results. The color change was measured according to the CIE L * a * b * system. Color changes were statistically analyzed using parametric one-way ANOVA and ANOVA with Welch correction, the nonparametric Kruskal-Wallis tests and post-hoc Tukey and Dunnet T3 with p≤ 0.05. Results: The immersion of restorative materials in different pigmentation agents caused a significant color variation on the samples. The agent who presented higher results was the Peach Ice Tea(r). The chocolate milk was the fluid with lowest pigmentation capacity of all restorative materials under study. The greater color variation was found on the Ketac(tm) Molar submerged in Coca-Cola(r) and the smallest on the Filtek(tm) z250 in chocolate milk. Conclusion: All restorative materials were shown to be susceptible to pigmentation by all agents. The Filtek(tm) z250 proved to have better color stability, followed by Photac(tm) Fil and finally by Ketac(tm) Molar.

Published: January 2016

Objective: To evaluate the occlusal aspects of patients with and without noncarious cervical injury and identify its risk factors. Method: Through a cross-sectional study, 88 patients of both sexes between 18 and 71 years old were evaluated, in Occlusion services in the cities of João Pessoa and Campina Grande. Clinical assessments were performed by a single calibrated examiner to check the occlusal aspects of patients with and without injuries, through descriptive and non-parametric analysis with 5% significance level and 95% of confidence interval. Results: Parafunctional habits were identified at a frequency of 92.0% of the patients. Unilateral chewing was not associated with the presence of lesions. The side disocclusion by the canine was prevalent in the whole sample. Occlusal interference in maximal intercuspal position and in nonworking side were presented as risk factors for the higher number of lesions and their development. Wear facets were common in the premolar groups and the maxillary arch in patients with lesions. Conclusion: Occlusal factors pose risks for the development and greater number of noncarious cervical lesions.

Methods: a prospective cohort study with a sample of 30 preterm newborns that weighed under 1500 g and were hospitalized in the NICU of the university hospital. Data were collected from January to December 2013 using a structured instrument. Results: of the 30 neonates included in the study, 14 developed late-onset neonatal sepsis with a prevalence of coagulase-negative staphylococci. Conclusions: the incidence of late-onset neonatal sepsis indicates a vulnerability in preterm infants due to immunological immaturity. These results reveal that knowledge of the profile of newborn infants admitted to the NICU and the risk factors to which they are exposed are central to the planning of nursing care for these patients. Future studies should address strategies for preventing nosocomial infection.

O Valongo de Machado na cartografia do Rio de Janeiro: a escravidão em cena na cidade
Authors: Jordão Rogério Pacheco
Published: January 2016

Resumo Este artigo discute, em diálogo com passagens selecionadas de Machado de Assis, o que pode condensar, na contemporaneidade, o nome próprio Valongo, lugar de desembarque de centenas de milhares de africanos e onde operou, no Rio de Janeiro, o maior mercado de escravos do Brasil Colônia e Império. Esquecido dos mapas e do imaginário da cidade por quase duzentos anos, o Valongo foi "redescoberto" arqueologicamente no ano de 2011, no seio de uma ampla reforma urbanística da área portuária carioca, o projeto Porto Maravilha. Nestes termos, faz-se aqui uma reflexão a respeito da potência da prosa machadiana para a leitura do passado escravista brasileiro e suas heranças.

Although papaya world production is high, the integument of papaya seeds, called sarcotesta, is an obstacle in the seedling production process. The aim of this work was to develop techniques to facilitate the removal of papaya seed sarcotesta for seedlings production. For that, two assays were developed. For the first one, the seeds were immersed in different concentrations of active chlorine (0, 2, 4, 6 and 8%) at ratio 600:200 seeds/mL of solution, respectively, besides the study of intact seeds and seeds subjected to the sieve method + stagnant water. For the second one, the seeds were immersed in active chlorine 2% in different ratios (10: 200; 200: 200; 400: 200 and 600: 200), and the concentration of 0% at ratio 10:200 and the sieve method + stagnant water. The effect of the treatments was evaluated by germination test and scanning electron microscopy. Sodium hypochlorite did not remove completely sarcotesta, but damaged it. In ratio 10:200 in a concentration of 2% of active chlorine for 24 hours, the embryo and the endosperm were not affected, resulting in 80% of germination, which can be an alternative to sarcotesta manual removal.

The Paramirim Corridor represents the maximum inversion zone of the Paramirim Aulacogen. Reverse-to-reverse dextral shear zones and various types of folds dominate such corridor. These structures reflect a stress field that is WSW-ENE oriented, developed in units of Aulacogen basement, as well as in the Lagoa Real Intrusive Suite, of Statherian age, in Espinhaço and São Francisco supergroups, of Statherian-Tonian and Cryogenian ages, respectively, and in the Macaúbas-Santo Onofre Group, of Tonian age at the most. A rich collection of extensional structures truncate compressional structures of the Paramirim Corridor, characterized by normal shear zones and foliation, which is sometimes mylonitic, down-dip stretching lineation, drag folds, traction fractures and S/C structures. In these shear zones, quartz occurs truncated by the foliation, while feldspars are fractured and altered to white mica. Distribution of the quartz c-axes is at a maximum of 14° from the Z-axis. Thus, it suggests that the deformation activated mainly the basal glide planes in the  direction. The paleostress study using the Win-Tensor software demonstrated that the regimen ranged between radial and pure distention. The S1 direction oscillated around a vertical trend, while s3 was sub-horizontal, with a predominant N230-050° direction. Ar-Ar ages in biotite obtained from the extensional shear zones ranged from 480 and 490 Ma. Together, data obtained for the structures associated with the late extensional regimen described in the present study suggest that its nucleation is associated with distal and brittle-ductile sectors of the gravitational collapse zone of Araçuaí-West Congo Orogen.
Mineralogia, geoquímica e evolução da lateritização em Apuí, sudeste do Amazonas

Published: January 2016

Análises químicas, DRX e MEV realizadas em bauxitas, crostas ferruginosas e ferro-alumino-silicosas, aliadas ao estudo do relevo, tiveram por objetivo discutir os processos que levaram a formação e preservação das crostas lateríticas ao longo do tempo geológico no sudeste do Amazonas. As crostas são maciças, pisolíticas, brechóides e vermiformes, sustentam platôs e colinas com altitudes entre 200 e 320 m e 140 e 200 m, e desenvolveram-se a partir de rochas ígneas e sedimentares dos grupos Colíder e Alto Tapajós e do Supergrupo Sumaúma. A correlação entre os produtos da lateritização e as rochas identificou três associações: (1) congrega arenitos, vulcânicas e siltitos em razão da associação SiO2-Ba-Rb; (2) agrupa bauxitas e solos relacionados Al2O3-TiO2-PF-Y-Ta-Nb-U-Th-Ga-Hf-Zr-ETR; (3) reúne a bauxita pisolítica, crostas ferruginosas e ferro-alumino-silicosas vinculadas a Fe2O3-Ag-As-Ni-Pb-V. Aspectos geoquímicos e a ausência de seixos quartzosos indicam que o protólito da bauxita maciça e do solo sobrejacente é a rocha vulcânica, enquanto a bauxita pisolítica e a crosta vermiforme ferro-alumino-silicosa derivam dos arenitos do Supergrupo Sumaúma, e as demais crostas ferruginosas a ferro-alumino-silicosas correlacionam-se ao Grupo Alto Tapajós. As ações erosivas foram facilitadas pela incisão dos rios Aripuanã, Acari e Sucunduri; pelo condicionamento de grábens e horsts; e pelas épocas mais secas no Quaternário Amazônico, que resultaram em relevo dissecado, perfis truncados, formação de linhas de pedra e solo pouco espesso.
Applications and limitations of thermobarometry in migmatites and granulites using as an example rocks of the Araçuaí Orogen in southern Bahia, including a discussion on the tectonic meaning of the current results

In southern Bahia, there are outcrops of migmatites and granulites in the Jequitinhonha Complex, which is part of the northern portion of the Araçuaí Orogen. Migmatites (garnet-cordierite diatexite) dominate the metamorphic rocks and host lenses and layers of felsic garnet granulite. The conditions of temperature and pressure of metamorphism were calculated using conventional thermobarometry and the software THERMOCALC. Values around 850 °C and 7 kbar were obtained with THERMOCALC. The calculations for the garnet-cordierite diatexite were made considering aH2O equal to 1, but the best results of calculations for the granulites are obtained with aH2O values of 0.3. Pressure values obtained with GAPES resulted in consistent values with THERMOCALC, but the pair garnet-orthopyroxene always produces low values for temperature and high ones for pressure. The results are consistent with the presence of the pair garnet and cordierite in diatexite and orthopyroxene in felsic granulite. From the tectonic point of view, the setting in which metamorphism of these rocks occurred requires high heat flow with a thermal anomaly in mid continental crust, as indicated by values of 7 kbar. Recent studies have favored the closure of a back-arc basin for this tectonic setting, but it does not solve the problem that the time span between metamorphic peak and the end of granite intrusions, involving large bodies of charnockite, is more than 80 million years. The model of tectonic switching is suggested here as it can explain the maintenance of high temperatures for a more extended interval of time.

Paracoccidioidomycosis and histoplasmosis are systemic fungal infections endemic in Brazil. Disseminated clinical forms are uncommon in immunocompetent individuals. We describe two HIV-negative patients with disseminated fungal infections, paracoccidioidomycosis and histoplasmosis, who were diagnosed by biopsies of suprarenal lesions. Both were treated for a prolonged period with oral antifungal agents, and both showed favorable outcomes.

Published: January 2016

Background: Prolonged preoperative fasting may impair nutritional status of the patient and their recovery. In contrast, some studies show that fasting abbreviation can improve the response to trauma and decrease the length of hospital stay. Aim: Investigate whether the prescribed perioperative fasting time and practiced by patients is in compliance with current multimodal protocols and identify the main factors associated. Methods: Cross-sectional study with 65 patients undergoing elective surgery of the digestive tract or abdominal wall. We investigated the fasting time in the perioperative period, hunger and thirst reports, physical status, diabetes diagnosis, type of surgery and anesthesia. Results: The patients were between 19 and 87 years, mostly female (73.8%). The most performed procedure was cholecystectomy (47.69%) and general anesthesia the most used (89.23%). The most common approach was to start fasting from midnight for liquids and solids, and most of the patients received grade II (64.6%) to the physical state. The real fasting average time was 16 h (9.5-41.58) was higher than prescribed (11 h, 6.58 -26.75). The patients submitted to surgery in the afternoon were in more fasting time than those who did in the morning (p<0.001). The intensity of hunger and thirst increased in postoperative fasting period (p=0.010 and 0.027). The average period of postoperative fasting was 18.25 h (3.33-91.83) and only 23.07% restarted feeding on the same day. Conclusion: Patients were fasted for prolonged time, higher even than the prescribed time and intensity of the signs of discomfort such as hunger and thirst increased over time. To better recovery and the patient's well-being, it is necessary to establish a preoperative fasting abbreviation protocol.
