Authors: Tsiouris Athanasios , Morgan Jeffrey A. , Nemeh Hassan W. , Hodari Arielle , Shah Rupen , Brewer Robert J. , Paone Gaetano
Published: May 2014

Background: Acuity models to predict survival after left ventricular assist device (LVAD) implantation do not include operative status as one of the calculated variables. The effect of elective versus emergent LVAD implantation on outcomes has not been examined.

Methods: Patients were stratified into 2 groups based on operative status (elective versus emergent). Variables were compared to determine whether there were differences in outcomes between elective versus emergent LVAD recipients

Results: Of the 130 patients, 59 underwent an elective procedure, whereas 71 had their LVAD implanted as an urgent/emergent operation. Patients in the urgent/emergent cohort had significantly worse preoperative hepatic and renal function and higher central venous pressures. Survival rates at 30 days, 6 months, 1 year, and 2 years were analogous for both cohorts. Patients in the emergent cohort had a higher incidence of postoperative right ventricular failure, with the requirement for short-term right ventricular support in 9.9% versus 1.7% (P = 0.054). The incidence of other LVAD-related complications, were similar in both groups. Emergency status did not predict postoperative mortality in univariate analysis.

Conclusions: Although patients who underwent emergent LVAD implantations had worse preoperative renal and liver function and a higher incidence of postoperative right ventricular failure, they exhibited similar midterm survival and a similar incidence of other postoperative complications.

Published: May 2014

An 83-year-old male with a history of three prior sternotomies, including coronary artery bypass surgery (CABG), presented with unstable angina. Cardiac catheterization showed left main and triple-vessel disease. The saphenous vein graft (SVG) to the right coronary artery was diseased but patent, and the SVG to the left anterior descending artery (LAD) was occluded. Preoperative evaluation showed a heavily calcified ascending aorta and minimum disease on the descending aorta. He successfully underwent a left thoracotomy 2-vessel off-pump CABG using the descending aorta for the proximal anastomosis. The left thoracotomy approach is a useful alternative to avoid complications associated with resternotomy, especially in patients with a hostile chest, although visualization of the target vessels may be limited.

Published: May 2014

Introduction: Interrupted aortic arch is a rare congenital malformation characterized by a complete loss of luminal continuity between the ascending and descending aorta. It is often diagnosed during the neonatal period.

Case presentation: We presented a 51-year-old male patient with interrupted aortic arch type B who was treated successfully with posterolateral thoracotomy without using cardiopulmonary bypass.

Conclusion: The prognosis for interrupted aortic arch depends on the associated congenital anomalies, but the outcome is usually very poor unless there is surgical treatment. Survival into adulthood depends on the development of collateral circulation.

Authors: Rawat Paridhi , Aeran Himanshu , Agarwal Anubha , Nautiyal Vijay
Published: May 2014

Background & Objectives:

Infections caused by blood-borne pathogens like HCV, HBV or HCV have emerged as a hurricane for health-care workers. Among them, Hepatitis-B is a leading cause of morbidity & mortality all around the world especially placing health workers at higher occupational risks. Also percutaneous injuries in dental clinic are risk factors for transmission of HBV. Hence a bi-directional relationship exists between dentist & patient regarding transmission of HBV. The present study is designed to evaluate degree of awareness & knowledge about HBV & status of vaccination against it, among the dental students & clinicians.

Methods:

A cross-sectional study was conducted on 279 dental professionals including 41 clinicians, 45 post-graduate students, 80 interns and 113 B.D.S III & IV Yr students by means of a questionnaire. Data was collected & then analyzed in SPSS version-16.

Result:

Our results were noteworthy that nearly 89.6% claimed that hepatitis-b is preventable. Positively, 90.71% subjects were vaccinated against HBV & 62.8% showed positive attitude towards HBV+ patients. However, some alarming findings are that 54.64% didn’t know about post-exposure prophylaxis and 79.84% didn’t have any idea about serum HBV DNA viral load considered safe according to CDC.

Conclusion:

The present study consolidates the urgent need for further spread of knowledge & awareness about Hepatitis-B. We also highlight practice of “Standard Infection Control” measures and strict adherence to tenets of CDC guidelines. Hence the call of the hour is to spread awareness about Hepatitis-B which can turn to be a “mouse or an elephant in dental clinic.”
Prevalence of Eruption of Third Molar Tooth among South Indians and Malaysians
Authors: Ren Calvin Gan Chee , Kumar B. Senthil
Published: May 2014

Introduction:

In prehistoric humans, when the jaw size permitted space for normal dental development and position in the arches, third molar may have been a vital survival tool. However, as human evolution has progressed, jaw size has been gradually decreasing (Lamarckian Evolution). Hence due to the decrease in size of the jaw bone, it’s been reported that approximately 65% of the human population has at least one impacted third molar, and third molars that do erupt are often malposed in the arches and are consequently difficult to clean and prone for infection.

Aim and Objective:

To study the prevalence of eruption of third molar tooth among South Indians and Malaysians by observing the presence of third molars among them and to analyze the percentage of impacted third molars and congenital absence of third molar teeth among the Indian and Malaysian population.

Materials and Methods:

50 Malaysians and 50 Indians (25 males and 25 females in each population) aged between 17 to 25 years old were examined for the presence or absence of the third molars. To confirm the congenital absence of third molars, Orthopantomograms (OPG) were taken.

Results and Conclusion:

In South Indian Population, it was noted that only 48% of males and 64% of females have congenital absence of third molar, and 52% of males and 36% of females have erupted third molars. 16% of males had partly impacted third molar whereas in case of female it was 28%. Congenital absence of third molars among females was 16% more than in males. More males (36%) had impacted third molars than females (24%). It was also noted that majority of them have their maxillary third molars erupted first before their mandibular third molars. In Malaysian Population, it was noted that only 28% of males and 20% of females had congenital absence of third molars, and 72% of males and 80% of females had erupted third molars. 40% of males had partly impacted third molar whereas in case of female it was 52%. Congenital absence of third molars among males was 8% more than females. More males (32%) had impacted third molars than females (28%). It was also noted that in majority of them their mandibular third molars had erupted before their maxillary third molars. When compared among south Indians and Malaysian population congenital absence and impacted third molars are more common in south Indians, whereas partly impacted third molar is more common among Malaysians.

Published: May 2014

Este estudo buscou conhecer expectativas e percepções dos acadêmicos de Odontologia da Universidade Estadual de Montes Claros, MG, Brasil, em relação ao atendimento aos pacientes com HIV/Aids. Utilizaram-se observação participante e entrevistas semiestruturadas com nove acadêmicos, sendo identificadas três categorias de análise: ”A expectativa do atendimento na clínica de HIV/Aids”, “O medo de infectar-se” e “Mudança de comportamento”. Percebeu-se que, anterior ao contato com os pacientes, as caracterizações construídas pelos acadêmicos eram estereótipos sociais, como: pessoas magras, homossexuais masculinos e aspecto deprimido. O medo foi observado pela tendência em superestimar os riscos de transmissão, mudando os comportamentos em relação à biossegurança. A etnografia proporcionou perceber a importância da prática clínica odontológica no cotidiano acadêmico, aliada à biossegurança no rompimento dos paradigmas e preconceitos com o paciente com HIV/Aids.

Functional magnetic resonance imaging in oncology: state of the art
Authors: Guimaraes Marcos Duarte , Schuch Alice , Hochhegger Bruno , Gross Jefferson Luiz , Chojniak Rubens , Marchiori Edson
Published: May 2014

In the investigation of tumors with conventional magnetic resonance imaging, both quantitative characteristics, such as size, edema, necrosis, and presence of metastases, and qualitative characteristics, such as contrast enhancement degree, are taken into consideration. However, changes in cell metabolism and tissue physiology which precede morphological changes cannot be detected by the conventional technique. The development of new magnetic resonance imaging techniques has enabled the functional assessment of the structures in order to obtain information on the different physiological processes of the tumor microenvironment, such as oxygenation levels, cellularity and vascularity. The detailed morphological study in association with the new functional imaging techniques allows for an appropriate approach to cancer patients, including the phases of diagnosis, staging, response evaluation and follow-up, with a positive impact on their quality of life and survival rate.
The carpal boss: a review of different sonographic findings
Authors: Arend Carlos Frederico
Published: May 2014

Carpal boss is an uncommon condition whose incidence is underestimated and that is frequently confused with other causes of development of tumor-like lesions on the dorsum of the wrist. From the clinical point of view, the main obstacle to its recognition is the nonspecificity of symptoms, frequently attributed to dorsal ganglion cysts, since both conditions share a similar location on the dorsum of the wrist. The assessment by ultrasonography allows for a correct diagnosis and appropriate management, with better chances of resolution of the clinical complaint and lower probability of iatrogenic worsening of the lesion. The present review is aimed at describing the different sonographic findings of carpal boss.

Published: May 2014

A água nas áreas de extrativismo de ostras do Estuário de Cananeia foi avaliada por meio da análise colimétrica durante o período de 2005 a 2011. Averiguou-se que a média geométrica dos coliformes termotolerantes (18,80 NMP.100mL-1) está dentro dos limites permitidos pelo CONAMA 357/2005, mas o percentil não alcançou o mínimo estabelecido pela Resolução (80%). Verificou-se que houve correlação positiva entre coliformes com o fator pluviosidade e correlação negativa com a salinidade. Constatou-se também que a preamar de sizígia apresentou menor densidade de coliformes e diferiu significativamente dos outros estofos analisados. Concluiu-se que a concentração de coliformes nos locais analisados demonstrou variabilidade temporal e que sofre influência direta de salinidade, pluviosidade e amplitude de maré.

Foi conduzido um estudo clínico, randomizado, duplo-cego e controlado por placebo, no qual mulheres idosas foram randomizadas para compor quatro grupos: 1) suplementação com placebo (PL; n = 10); 2) suplementação com creatina (CR; n = 10); 3) suplementação com placebo associado ao treinamento de força (PL+TR; n = 6); e 4) suplementação com creatina associado ao treinamento de força (CR+TR; n = 8). Antes (PRE) e após 24 semanas (POS) de intervenção, foram coletadas amostras de sangue para posterior análise das concentrações plasmáticas de hidroperóxidos lipídicos por espectrofotometria. Nenhuma diferença estatística foi observada na concentração de hidroperóxidos lipídicos entre os grupos (PL: PRE = 48,7 ± 36,9; POS = 29,3 ± 18,8; delta = -13,0 ± 26,8; CR: PRE = 51,0 ± 46,0; POS = 54,2 ± 51,6; delta = -8,6 ± 30,2; PL+TR: PRE = 33,0 ± 11,2; POS = 47,3 ± 31,6; Δ = 14,3 ± 39,2; CR+TR: PRE = 18,5 ± 10,1; POS = 28,1 ± 17,9; delta = 9,7 ± 16,4 pmol.mg-1 de proteína total; p = 0,17). A suplementação de creatina associada ou não ao treinamento de força não afetou a peroxidação lipídica, um importante marcador de estresse oxidativo no plasma, em mulheres idosas.

Published: May 2014

O presente estudo teve como objetivo criar e validar uma bateria de testes motores relacionados à atividade da vida diária (AVD), com o intuito de avaliar a independência funcional de indivíduos com lesão na medula espinal. Para tanto, foram selecionados 22 sujeitos por conveniência, com idades variando entre 20 e 53 anos. Esses indivíduos foram submetidos à realização de uma bateria de testes, a qual passou por processo de verificação da validação por conteúdo, objetividade e reprodutibilidade. Os dados foram tratados através de estatística descritiva, Análise de Variância (ANOVA- "one-way"), Coeficiente de Correlação Intraclasses e teste t-Student. Adotou-se a = 5%. Os principais resultados demonstraram que os testes que compõe a bateria possuem descrição clara, relacionam-se com AVD e possuem aplicabilidade, o que torna válido seu conteúdo. Além disso, todos os testes demonstraram alto grau de objetividade (p = 1,00 e F = 0,00) e reprodutibilidade (CCI > 0,85). A elaboração desta bateria de testes específicos para pessoas com lesão na medula espinhal pode ser uma ferramenta útil para avaliar de forma efetiva e com qualidade alguns parâmetros relevantes do seu dia a dia, de modo a analisar a independência dos sujeitos.
Momentos iniciais da educação física em Goiás (1917-1929)
Authors: DIAS Cleber
Published: May 2014

Este artigo analisa os momentos iniciais da organização institucional da educação física em escolas de Goiás, valendo-se de legislações, jornais, fotografias, livros de memórias e documentos oficiais como fontes. Desenvolvendo uma abordagem da história regional, o trabalho argumenta que o período entre 1917 e 1929 foi crucial para o início desse processo. Mais especificamente, uma combinação de interesses civis e militares, nacionais e regionais, de dentro e de fora de Goiás, parece ter sido o principal responsável por esse processo de construção social da educação física na região.

Published: May 2014

O objetivo desse estudo foi verificar o desenvolvimento de conceitos, níveis de aptidão física relacionados à saúde, e padrão de atividade física proporcionado pelas aulas de Educação Física (EF). Compuseram a amostra 40 alunos (24 meninos, 16 meninas) do ensino médio. A aptidão física (APF) foi avaliada mediante os testes sentar e alcançar, corrida de nove minutos e resistência abdominal em um minuto, pertencentes à bateria de testes da PROESP. Os conceitos foram analisados por prova teórica com questões objetivas. O escore de atividade física (ATF) foi estimado pela versão longa do International Physical Activity Questionaire (IPAQ). Em 30 aulas de EF os conteúdos de ensino se relacionaram aos conceitos sobre alongamento e exercícios gímnicos: ginástica intervalada e corridas. Encontraram-se mudanças significativas na resistência abdominal, flexibilidade e conhecimento para ambos os sexos e na resistência aeróbia para meninas, indicando que as aulas, trabalhadas mediante procedimentos de ensino visando à promoção da saúde podem modificar os conceitos e a aptidão física relacionados à saúde de alunos do Ensino Médio.

Alternative methods are being developed to reduce, refine, and replace (3Rs) animals used in experiments, aimed at protecting animal welfare. The present study reports alternative tests which are based on the principles of the 3Rs and the efforts made to validate these tests. In Europe, several methodologies have already been implemented, such as tests of irritability, cell viability, and phototoxicity as well as in vitro mathematical models together with the use of in silico tools. This is a complex process that spans from development to regulatory approval and subsequent adoption by various official entities. Within this regulatory framework is REACH, the European Community Regulation for chemicals and their safe use. In Brazil, the BraCVAM (Brazilian Center for the Validation of Alternative Methods) was recently established to validate alternative methods and stimulate incorporation of new methodologies. A new vision of toxicology is emerging for the 21st century (Tox-21), and the subsequent changes are shaping a new paradigm.

Objective

To study the growth of children with complete unilateral cleft lip and palate (UCLP) from 2 to 10 years of age and to assess whether growth varied from that of children without UCLP (typical children).

Design

Physical growth was one of the outcome measures of a National Institutes of Health–sponsored longitudinal, prospective clinical trial conducted by the University of Florida and the University of São Paulo.

Setting

Hospital of Rehabilitation of Craniofacial Anomalies, University of São Paulo (HRAC-USP), Bauru, Brazil.

Main Outcome Measures

Height and weight were prospectively measured for 360 healthy children with UCLP who were nonsyndromic, belonged to median socioeconomic status, and received health care at HRAC-USP. To compare growth of children with UCLP to that of typical children, growth curves for UCLP were developed and compared with World Health Organization curves for 2006 and 2007, which were used as reference for typical children. Third-degree polynomials were used to explain the relationship of length and weight with age. Confidence limits of 95% were used for the mean curve using the statistic Z ~ N (0,1).

Results

Children with UCLP from 2 to 10 years old presented height and weight growth curves similar to those of typical children for both genders.

Conclusion

Children with UCLP from 2 to 10 years old presented physical growth similar to that of typical children.

Background.

A rapid surge of young-female breast cancer (YFBC) has been observed in Taiwan and other East Asian countries. We recently reported that these cases of YFBC, in contrast to their Western counterparts, are predominantly luminal A subtype. YFBC in Asia may have distinct clinicopathological features and outcomes.

Methods.

Data collected prospectively by participating hospitals were retrieved from the Taiwan Cancer Database. A total of 15,881 women with newly diagnosed stage I–III breast cancer in 2002–2006 were included. The age at diagnosis was categorized into nine 5-year groups (from <30 years to ≥65 years). Clinicopathological variables and patient disease-free survival (DFS) were compared by age group.

Results.

The rates of stage I, estrogen receptor-positive (ER+), and progesterone receptor-positive breast cancer were higher in the younger patients (<50 years) than in the older patients (≥50 years). Univariate analysis showed that the 40–44 and 45–49 age groups were significantly associated with longer DFS than the other age groups. In the ER+ subgroup, multivariate analysis consistently showed that the 40–44 age group was significantly associated with longer DFS than the other age groups except for the 45–49 age group. In contrast, multivariate analysis of the ER-negative subgroup revealed no significant difference of DFS between the 40–44 age group and other age groups.

Conclusion.

Emerging YFBC in Taiwan is uniquely associated with favorable pathological features and better outcomes and should not be regarded as the mirror image of its Western counterpart.
Phylogenetic Analysis of the Spiny Oryctocephalids (Trilobita, Corynexochida?, Oryctocephalidae), Cambrian
Authors: Sundberg Frederick A.
Published: May 2014

Phylogenetic analyses of the Cambrian spiny oryctocephalids support the elevation to familiar rank of Oryctocephalidae Beecher, 1897 and indicate that the family can be divided into two clades, here designated as the subfamilies Oryctocephalinae Beecher, 1897 and Lancastriinae Kobayashi, 1935. Curvoryctocephaliinae Zhao and YuaninYuan et al., 2002 is considered here a junior synonym of Lancastriinae. Oryctocephalinae have tapered or parallel sided glabella and is composed of species ofOryctocephalusWalcott, 1886. The subgeneraOryctocephalus(Oryctocephalus) andO. (Eoryctocephalus) Zhao and YuaninYuan et al., 2002 do not form separate clades and are here rejected.

The genera of the Lancastriinae have expanding glabellae. The subfamily is composed of a broad variety of genera that can be divided into three major subclades:Lancastria,Protoryctocephalus, andOryctocephalites. TheLancastriasubclade is composed ofLancastriaKobayashi, 1935,ChangaspisLeeinChien, 1961, andGoldfieldiaPalmer, 1964 occurring at the base of the Lancastriinae.GoldfieldiaandLancastriaform a sister group toChangaspis. The long branches in the phylograms indicated significant differences between these taxa; thus, the genusGoldfieldiais maintained. TheProtoryctocephalussubclade is monogeneric and forms a sister group to theOryctocephalitessubclade. TheOryctocephalitessubclade consists of several species of this genus and the more derived formsMetabalangiaQian and YuaninZhang et al., 1980 andTonkinellaMansuy, 1916.OryctocephaloidesYuaninZhang et al., 1980 is considered a junior synonym ofOryctocephalitesResser, 1939. The subgeneraOryctocephalites(Oryctocephalites) andO. (Parachangaspis) Zhao and YuaninYuan et al., 2002 do not form separate clades. The later subgenus occurs in the basal portion of theOryctocephalitessubclade indicating that it is a paraphyletic taxon.

OpsiosoryctocephalusSundberg, 1994,OryctocephalopsLermontova, 1940, andCurvoryctocephalusZhao and YuaninYuan et al., 2002 are not consistent in their placement within the phylogenetic analyses, although they always occur in the Lancastriinae. As a result they are not placed within a subclade within Lancastriinae.

The type speciesGoldfieldia pacificaPalmer, 1964 was based solely on cranidia. This species is redescribed using topotype material that includes cranidia, librigenae, hypostomes, thorax, and pygidia.
