Treatment and evaluation of talus neck fracture
Authors: Tadvi Niranjan D.
Published: July 2017

Background: Talus fractures rank second in frequency of all tarsal bone injuries and talar neck fractures account for approximately 50% of these. The purpose of this study was to evaluate clinical and radiological outcomes with a long follow-up of displaced and operatively treated talar fractures.

Methods: The study was a prospective study of ten cases of closed talar neck fracture evaluated and treated at the Department of orthopaedics, Sir.T.Hospital, Bhavnagar from 19 May 2011 to 17 March 2013. Out of ten patients, nine turned up for follow up, one was lost.

Results: Reduction was anatomical in five cases (50%), nearly anatomical in 3 cases (30%) and poor in two cases (20%). One patient (10%) developed an early superficial infection and required surgical irrigation and debridement and appropriate antibiotic treatment. Using the AOFAS ankle–hindfoot scale, the average functional score was 74.2 points. There was excellent result in one patient, good result in three cases, fair in six and no poor result fond.

Conclusions: Talar neck fractures (Hawkins type 2 and 3) treated with anatomical reduction and near anatomical reduction having satisfactory clinical and functional outcome, where as (Hawkins type 4) having fair to poor  outcome with complication like AVN, arthritis and malunion due to poor initial reduction.

Keywords: Talus neck fractures, Avascular necrosis, AOFAS ankle–hindfoot scale, Hawkins type offracture
Maturity Assesment: A Case of Micro and Small Service Enterprises
Authors: Carballo-Mendivil Blanca, , Arellano-Gonzalez Alejandro, , Ríos-Vazquez Nidia Josefina,
Published: July 2017

High percentages of Micro and Small-sized enterprises (MSEs) perish in their initials years of business. That is why various efforts have been made to know their operation and improve it. However those proposals of improvement are mostly based in reductionist diagnostics that limit the understanding of their business processes. This paper presents an integral diagnostic of MSEs, specifically in the service sector in the north of Mexico, through which the maturity level of its processes is determined. The design was descriptive exploratory with a quantitative approach. A rubric-type instrument was applied, which was designed to perform an integral diagnosis and measure the maturity level of the processes in 140 companies. The results indicate that the maturity levels of the business processes in the service sector are mostly craft-like. The elements with the lowest maturity levels include service assessment as part of management, the capacity to design new services/processes, evaluation and selection of suppliers, and improvements to the purchasing process that can assure an appropriate level of service. The need to implement improvement projects in areas related to planning, monitoring, control and information support systems were also detected. The main contribution of this work is having defined the service sector of the municipality where the organizations under study are located, which will help entrepreneurs in the sector, to improve their knowledge on the area in which they operate; researchers decide to make more contributions to the sector; and clients obtain information about the business they purchase from.
On the Acquisition of Derivational Suffixes by Kuwaiti EFL Learners
Authors: Alotaibi Maye A. , Alotaibi Abdullah M.
Published: July 2017

This study aims to test the extent to which 90 Kuwaiti EFL learners are aware of the correct use of derivational suffixes in English. It also identifies the mains reasons of the errors that Kuwaiti EFL learners may make. In addition, it investigates whether the English proficiency level of the participants plays a role in their answers on the test. To this end, the participants were tested twice in this study; a multiple-choice test was used to check their comprehension skills, whereas a fill-in the blank test was used to measure their ability to produce the correct derivational suffixes in English. Following data analysis, the results reveal that Kuwaiti EFL learners are fairly aware of the correct use of English derivational suffixes to a certain degree; the total mean on both tests (comprehension = 70% and production = 56%) is 63%. The participants obtained higher percentage of correct answers on the comprehension test (mean= 70%) compared to the production test (mean = 56%). Additionally, the t-test shows that the participants’ English proficiency level plays a central role in their comprehension and production of these suffixes. The performance of the Advanced Learners (ALs) (comprehension = 77% and production = 62%) is better than that of the Intermediate Learners (ILs) (comprehension = 64% and production = 48%) on the tests. In particular, there is a statistically significant difference between the answers of ALs and ILs on both tests. Regarding the types of error made by the participants, I argued that the most noticeable ones are due to: (1) the modification that non-neutral derivational suffixes cause when they are attached to the word (stems/roots); and (2) first language (L1) influence. Finally, the study concludes with some recommendations for further research.

Authors: Alvares Robson Pereira , Henkes Jairo Afonso
Published: July 2017

O presente trabalho constitui-se em um estudo de viabilidade da aplicação do Mode-lo Digital de Elevação – MDE, elaborado a partir dos dados da missão “Shuttle Ra-darTopography Mission” (SRTM), no intuito de verificar se um mapa de declividade elaborado através deste insumo permite a delimitação de áreas de preservação permanente em encostas. A metodologia adotada utilizou dados vetoriais do Siste-ma Cartográfico do Distrito Federal para confecção de um MDE que serviu de base comparativa para análise do MDE do SRTM. Foram utilizadas ferramentas de geo-processamento na execução das seguinte tarefaz: conversão da base vetorial e da-dos matriciais ao mesmo sistema de coordenadas, geração do modelo irregular de triangulação que originou o MDE do SICAD, comparação dos insumos através de imagens de diferença e estatística dos dados. Todos os dados foram analisados a luz do decreto lei nº 89.817, de 20 junho de 84, que define o Padrão de Exatidão Cartográfica – PEC. Os resultados encontrados indicam o Padrão de Exatidão Car-tográfica Classe A referido a escala 1 : 100.000 para o MDE do SRTM, tomando-se como referência o modelo do SICAD, gerado a partir de base vetorial de PEC A na escala de 1: 10.000. Entretanto as regiões de maiores discrepâncias altimétricas em relação ao modelo de referência, foram encostadas nas áreas de encostas e topos de morros, permitindo concluir sua inviabilidade para uso no que tange o objeto da pesquisa.
Um social dividido, um não-lugar encenado pela fuga
Authors: Modesto Rogério , Anjos Liliane dos
Published: July 2017

O objetivo deste artigo é compreender o funcionamento discursivo de gestos de fuga textualizados em cenas prototípicas. Adotamos uma perspectiva discursiva materialista que nos permite pensar a fuga em sua relação com o simbólico, situando-a como prática que se quer de resistência no bojo das relações de poder, sem deixar de reconhecer uma possibilidade de resistência no espaço da contradição. As diferentes formulações visuais e sonoras colocadas em paráfrase fazem perceber regularidades que, remetidas ao interdiscurso, permitem compreender os movimentos dos sentidos na imagem em seus silêncios e em seus excessos capazes de textualizar o conflito por meio da denúncia.
A demanda de Marcovaldo: apropriando-se do banco-cama na cidade
Authors: Paula Fernanda Cristina de , Marandola Junior Eduardo
Published: July 2017

Esse artigo discorre sobre apropriação do espaço a partir de um conto do livro “Marcovaldo ou as estações na cidade”, de Italo Calvino. Mediante uma postura de escavação dos sentidos, acompanhamos Marcovaldo e sua principal demanda: encontrar a “natureza pura” no interior da cidade industrial. Discutimos essa demanda ao perscrutar os sentidos: da necessidade de Marcovaldo de escapar do espaço de desconforto, do seu desejo pelo espaço da tranquilidade, de suas estratégias (frustradas) de tornar um banco da praça em cama. Essas desventuras de Marcovaldo denotam a experiência de ser-no-mundo e como a apropriação está presente nela, levando-nos a refletir sobre como a apropriação do espaço participa da ontologia humana.
A casa que habito: relatos de um reassentamento urbano
Authors: Bressan Sidney , Lajús Maria Luiza de Souza
Published: July 2017

Esse artigo objetiva analisar a apropriação do espaço residencial, a partir dos relatos daqueles que o protagonizaram – famílias de baixa renda que moravam em áreas de risco e irregulares e que foram reassentadas em um conjunto de Habitação de Interesse Social denominado Vida Nova, na cidade de São Domingos/SC. Por meio de narrativas busca-se apresentar histórias particulares de lutas e superações em relação à antiga morada, bem como os fatores sociais, econômicos e culturais que podem ter contribuído no jeito peculiar de cada morador em apropriar-se do novo espaço. Considerar a moradia em seus fenômenos particulares e subjetivos demonstrou ser, tanto um agente conformador como propulsor para o modo de apropriação do espaço residencial.

Published: July 2017

O fenômeno da explosão informacional traz, às instituições de ensino e pesquisa, um grande desafio, que é o de extrair da enorme massa de dados, aquilo que parece ser relevante para o desenvolvimento de suas pesquisas e estudos. Diante disso, a seleção e sistematização de informações úteis para as universidades e seus pesquisadores parecem ser cada vez mais prementes e, nesse contexto, as bibliotecas digitais temáticas assumem importância central e despontam como uma nova tendência, no que concerne à sistematização da informação especializada para o acesso. Assim, o Sistema de Biblioteca da Unicamp, considerando as necessidades informacionais de seus pesquisadores e da sociedade criou a Biblioteca Digital Zika (BDZ), cujo objetivo é disponibilizar conteúdos científicos especializados que auxiliem no desenvolvimento de novas pesquisas relacionadas ao enfrentamento das doenças transmitidas pelo mosquito Aedes Aegypti. Os resultados deste projeto demonstram a relevância das bibliotecas no contexto social, científico e cultural de nossa sociedade, além de aumentar a visibilidade e importância do trabalho do profissional bibliotecário.

Avaliou-se a eficiência do choque térmico duplo para induzir tetraploidia em jundiá Rhamdia quelen em diferentes tempos pós-fertilização. Vinte mililitros de ovos (10, 15, 20, 25, 30 e 35 mpf í  minutos pós-fertilização) foram tratados com choque térmico quente (39 Â± 0,2Â°C) durante 3 min, seguido de choque térmico frio (1,0 Â± 0,1Â°C) durante 30 min. Um grupo controle foi utilizado. As taxas de fertilização e de eclosão foram medidas 12 hpf (horas pós-fertilização) e 30 hpf respectivamente. Decorridas 60 hpf, 25 larvas de cada unidade experimental foram fixadas para verificação da ploidia, por citometria de fluxo. A taxas de fertilização foram de 87,83% para o controle e de 23,4%; 28,5%; 30,4%; 20,0%; 30,3% e 36,7%, para os grupos tratados com choque térmico aos 10, 15, 20, 25, 30 e 35 mpf respectivamente. Encontraram-se tetraploides apenas nos grupos de ovos tratados aos 15 mpf e 20 mpf. Este é o primeiro trabalho de indução de tetraploidia em jundiá por choques térmicos quente e frio, o qual possibilitou o aperfeiçoamento dessa técnica.

Published: July 2017

A região Neotropical tem grande diversidade de caranguejos. No entanto, a diversidade de parasitos infestando esses crustáceos ainda é pobremente conhecida. No presente estudo foram registradas três novas ocorrências de Leidya distorta em Ucides cordatus no Sudeste do Brasil e no Nordeste da Venezuela. Os caranguejos foram coletados em manguezais da Venezuela (Cumaná) e do Brasil (Cananéia e São Vicente). Um total de 281 caranguejos foi capturado nessas localidades, sendo os indiví­­duos dissecados no laboratório para verificar a presença de L. distorta. Apenas três caranguejos estavam infestados com o bopirí­­deo Leidya distorta. A prevalência nos caranguejos foi muito baixa (1,1%) e diferiu de acordo com a localidade, sendo levemente alta em Cananéia (2,6%) e São Vicente (2,2%), quando comparada com Cumaná (0,5%). Este estudo apresenta novas ocorrências de Leidya distorta infestando o caranguejo-uçá Ucides cordatus na América do Sul, bem como uma revisão dos braquiúros que servem de hospedeiro para Leidya distorta.
Risk Factors for and Clinical Outcomes of Dysphagia After Anterior Cervical Surgery for Degenerative Cervical Myelopathy
Authors: Nagoshi Narihito , Tetreault Lindsay , Nakashima Hiroaki , Arnold Paul M. , Barbagallo Giuseppe , Kopjar Branko , Fehlings Michael G.
Published: July 2017

Background:

Although dysphagia is a common complication after anterior cervical decompression and fusion, important risk factors have not been rigorously evaluated. Furthermore, the impact of dysphagia on neurological and quality-of-life outcomes is not fully understood. The aim of this study was to determine the prevalence of and risk factors for dysphagia, and the impact of this complication on short and long-term clinical outcomes, in patients treated with anterior cervical decompression and fusion.

Methods:

Four hundred and seventy patients undergoing a 1-stage anterior or 2-stage anteroposterior cervical decompression and fusion were enrolled in the prospective AOSpine CSM (Cervical Spondylotic Myelopathy) North America or International study at 26 global sites. Logistic regression analyses were conducted to determine important clinical and surgical predictors of perioperative dysphagia. Preoperatively and at each follow-up visit, patients were evaluated using the modified Japanese Orthopaedic Association scale (mJOA), Nurick score, Neck Disability Index (NDI), and Short Form-36 Health Survey (SF-36). A 2-way repeated-measures analysis of covariance was used to evaluate differences in outcomes at 6 and 24 months between patients with and those without dysphagia, while controlling for relevant baseline characteristics and surgical factors.

Results:

The overall prevalence of dysphagia was 6.2%. Bivariate analysis showed the major risk factors for perioperative dysphagia to be a higher comorbidity score, older age, a cardiovascular or endocrine disorder, a lower SF-36 Physical Component Summary score, 2-stage surgery, and a greater number of decompressed levels. Multivariable analysis showed patients to be at an increased risk of perioperative dysphagia if they had an endocrine disorder, a greater number of decompressed segments, or 2-stage surgery. Both short and long-term improvements in functional, disability, and quality-of-life scores were comparable between patients with and those without dysphagia.

Conclusions:

The most important predictors of dysphagia are an endocrine disorder, a greater number of decompressed levels, and 2-stage surgery. At the time of both short and long-term follow-up, patients with perioperative dysphagia exhibited improvements in functional, disability, and quality-of life scores that were similar to those of patients without dysphagia.

Short-Term Outcomes Following Hip Fractures in Patients at Least 100 Years Old
Authors: Manoli Arthur , Driesman Adam , Marwin Rebecca A. , Konda Sanjit , Leucht Philipp , Egol Kenneth A.
Published: July 2017

Background:

The number of hip fractures is rising as life expectancy increases. As such, the number of centenarians sustaining these fractures is also increasing. The purpose of this study was to determine whether patients who are ≥100 years old and sustain a hip fracture fare worse in the hospital than those who are younger.

Methods:

Using a large database, the New York Statewide Planning and Research Cooperative System (SPARCS), we identified patients who were ≥65 years old and had been treated for a hip fracture over a 12-year period. Data on demographics, comorbidities, and treatment were collected. Three cohorts were established: patients who were 65 to 80 years old, 81 to 99 years old, and ≥100 years old (centenarians). Outcome measures included hospital length of stay, estimated total costs, and in-hospital mortality rates.

Results:

A total of 168,087 patients with a hip fracture were identified, and 1,150 (0.7%) of them had sustained the fracture when they were ≥100 years old. Centenarians incurred costs and had lengths of stay that were similar to those of younger patients. Despite the similarities, centenarians were found to have a significantly higher in-hospital mortality rate than the younger populations (7.4% compared with 4.4% for those 81 to 99 years old and 2.6% for those 65 to 80 years old; p < 0.01). Male sex and an increasing number of medical comorbidities were found to predict in-hospital mortality for centenarians sustaining extracapsular hip fractures. No significant predictors of in-hospital mortality were identified for centenarians who sustained femoral neck fractures. An increased time to surgery did not influence the odds of in-hospital mortality.

Conclusions:

Centenarians had increased in-hospital mortality, but the remaining short-term outcomes were comparable with those for the younger cohorts with similar fracture patterns. For this extremely elderly population, time to surgery does not appear to affect short-term mortality rates, suggesting a potential benefit to preoperative optimization.

Protected Time for Research During Orthopaedic Residency Correlates with an Increased Number of Resident Publications
Authors: Williams Benjamin R. , Agel Julie A. , Van Heest Ann E.
Published: July 2017

Background:

The Accreditation Council for Graduate Medical Education (ACGME) requires orthopaedic residency programs to promote scholarship and research, which manifest differently among programs. We assess the impact of protected research time during orthopaedic residency on the number of resident publications.

Methods:

Rotation schedules and resident names were collected from 125 ACGME-accredited U.S. orthopaedic residency programs. Protected research time was classified as 1 of 3 types: (1) block time, (2) longitudinal time, or (3) no dedicated time. In April 2016, we searched residents in postgraduate year (PGY)-3 to PGY-5 on pubmed.gov to generate all orthopaedic publications with a PubMed identifier published during residency. Each publication’s 2015 Thomson Reuters Journal Citation Reports 5-Year Journal Impact Factor and resident first authorship were noted. The number of PubMed identifiers for each program was summed and was divided by the number of residents in PGY-3 to PGY-5, giving a mean number of publications per resident. The relationship between output and program research time was compared using t tests and analysis of variance (ANOVA).

Results:

A total of 1,690 residents were included, with an overall mean number (and standard deviation) of 1.2 ± 2.4 publications per resident. Eighty-seven programs reported block time, 14 programs reported longitudinal time, and 24 programs reported no time. There was a significant difference (p = 0.02) in the mean number of publications per resident when compared between programs with protected time (1.1 ± 1.2 publications) and programs with no protected time (0.6 ± 0.5 publication). One-way ANOVA demonstrated a significant mean difference across the 3 groups (p < 0.001), with longitudinal time correlating with significantly greater output at 1.9 ± 1.8 publications than block time at 1.0 ± 1.0 publication or no time at 0.6 ± 0.5 publication, a difference that persisted when adjusted to include only impact factors of >0 and exclude case reports (p = 0.0015).

Conclusions:

Both the presence of and the type of dedicated research time correlate with residents’ research productivity; further consideration of protected research time during residency is warranted.

Clinical Relevance:

This article provides objective data with regard to research strategies in training orthopaedic surgeons.
The Fourth Year of Medical School: Time for Reassessment
Authors: Alman Benjamin A. , Purtill James J. , Pellegrini Vincent D. , Scoles Peter
Published: July 2017

Most U.S. medical schools follow the 4-year model, consisting of 2 preclinical years, core clinical experience, and a fourth year intended to permit students to increase clinical competency, to explore specialty areas, and to transition to residency. Although the design and delivery of Years 1 through 3 have evolved to meet new challenges and expectations, the structure of Year 4 remains largely unchanged. For most students considering a career in orthopaedics, Year 4 is a series of elective rotations in which educational objectives become secondary to interviewing for residency programs. Most accreditation bodies recognize the importance of attainment of competency over the duration of medical school as the goal of educating physicians, and thus, there is a growing interest in reexamining the traditional medical school curriculum with the goal of integrating the final phases of undergraduate education and the first phases of postgraduate education.

A literature search was undertaken to identify publications on the duration of medical education. Pilot approaches to competency-based integration of undergraduate medical school and postgraduate training in orthopaedic surgery were reviewed.

There have been few data suggesting that 4 years of medical education is superior to shorter-duration programs. Three approaches to competency-based integration of undergraduate medical school and postgraduate training are presented. Their goal is to use student and faculty time more effectively. Each approach offers the opportunity to lower the cost and to decrease the time required for Board Certification in Orthopaedic Surgery. Two approaches shorten the entire duration of medical school and graduate training by using various proportions of the fourth year to begin residency, and one approach expands the duration of orthopaedic training by starting in the fourth year of medical school and including training equivalent to a fellowship program into the residency experience.

The effectiveness of such programs will form the basis for revisions to the current orthopaedic training paradigm, resulting in a more effective, efficient, and integrated orthopaedic training curriculum.
An in Vivo Simulation of Isometry of the Anterolateral Aspect of the Healthy Knee

Published: July 2017

Background:

To assess the isometry of theoretical lateral extra-articular reconstruction (LER), we evaluated theoretical grafts attached to various points on the lateral femoral condylar area and to either Gerdy’s tubercle or the anatomic attachment site of the anterolateral ligament to the tibia.

Methods:

In 18 subjects, healthy knees with no history of either injury or surgery involving the lower extremity were studied. The subjects performed a sit-to-stand motion (from approximately 90° of flexion to full extension), and each knee was studied using magnetic resonance and dual fluoroscopic imaging techniques. The 3-dimensional wrapping paths of each theoretical LER graft were measured. Grafts showing the least change in length during the sit-to-stand motion were considered to be the most isometric.

Results:

The most isometric attachment site on the lateral femoral epicondyle to either of the studied tibial attachment sites was posterior-distal to the femoral attachment site of the fibular collateral ligament. The LER graft had a mean change in length of approximately 3%. Moving the femoral attachment site anteriorly resulted in increased length of the graft with increasing flexion; more posterior attachment sites resulted in decreased length with increasing flexion. Moving the attachment site in the proximal-distal direction had a less profound effect. Moving the tibial attachment site from Gerdy’s tubercle to the tibial attachment site of the anterolateral ligament affected the overall isometric distribution on the lateral femoral epicondyle.

Conclusions:

The most isometric attachment site on the femur for an LER would be posterior-distal to the femoral attachment site of the fibular collateral ligament. Different length changes for LER grafts were identified with respect to different femoral attachment sites. Desirable graft fixation locations for treating anterolateral rotatory instability were found posterior-proximal to the femoral fibular collateral ligament attachment.

Clinical Relevance:

The present data could be used both in biomechanical studies and in clinical studies as guidelines for planning LER surgical procedures.
Outcomes and Complications of Reconstruction with Use of Free Vascularized Fibular Graft for Spinal and Pelvic Defects Following Resection of a Malignant Tumor
Authors: Houdek Matthew T. , Rose Peter S. , Bakri Karim , Wagner Eric R. , Yaszemski Michael J. , Sim Franklin H. , Moran Steven L.
Published: July 2017

Background:

Following resection of malignant tumors of the spine and pelvis, reconstructive surgeons often face large structural defects. Unlike reconstruction in the extremities, wherein a free vascularized fibular graft (FVFG) is a highly utilized option for segmental osseous reconstruction, there are limited data on the use of an FVFG in the spine and pelvis. The aim of this study was to review our institution’s experience with reconstruction with use of an FVFG following oncological resection in the spine and pelvis.

Methods:

We reviewed 24 cases involving the use of an FVFG in reconstruction of segmental osseous defects of the spine and pelvis following oncological resection from 2000 to 2015. The cohort consisted of 12 male and 12 female patients with a mean age of 37 years and a mean follow-up of 5 years. Fifty-four percent of the reconstructions were spinopelvic or sacropelvic.

Results:

The overall 2, 5, and 10-year rate of survival was 76%, 55%, and 37%, respectively. With regard to disease-free survival, the overall 2, 5, and 10-year rate was 81%, 72%, and 48%. The overall rate of union was 86%, with a mean time to union of 7 months. Complications were common, with 83% of the patients sustaining at least 1 postoperative complication. Following the procedure, the mean Musculoskeletal Tumor Society rating was 53%.

Conclusions:

An FVFG provides a durable means of reconstruction of osseous defects in the spine and pelvis. Although patient function was acceptable following these large reconstructions, the rate of postoperative complications was high.

Reproductive biology of the strongspine silverbiddy, Gerres longirostris Lacepede, 1801, was studied by examining 1910 individuals collected fortnightly between May 2012 and January 2014 from the western Arabian Gulf, off Saudi Arabia. The samples were identified as 470 males, 1370 females and 70 undetermined. Maximum length observed was 30 and 40 cm (total length TL) for males and females, respectively. Overall sex ratio of males to females was found to be 1:3.1. This sex ratio was significantly different from the normally expected 1:1 ratio (p0.05). Females were significantly greater than males in all size classes between 20 and 34 cm with high significant difference (p30.28°C might not be optimal for reproduction of G. longirostris.
Nutritional and physical characteristics of noodles incorporated with green seaweed (Ulva reticulata) and fish (Pangasianodon hypophthalmus) mince
Authors: Debbarma Jesmi , Viji P. , Rao B. M. , Prasad M. M.
Published: July 2017

Nutritional and physical properties of noodles incorporated with green seaweed (Ulva reticulata) puree and fish (Pangasionodon hypophthalmus) mince were evaluated. Four lots of noodles were prepared using different formulations viz., control noodle without adding seaweed puree or fish meat (C); noodle with 20% cooked pangasius fish meat (T1), noodles with 20% seaweed puree (T2) and noodles with 10% seaweed puree and 10% cooked pangasius fish meat (T3). Proximate composition, cooking properties, textural and sensory qualities of noodles were assessed. Results indicated that addition of green seaweed puree increased the crude fibre content of noodles. Crude fibre content was higher in T2 (2.62±0.18%) followed by T3 (1.71±0.06%). Cooking time for noodles varied between 6.80±0.71 and 9.15±0.21 min and cooking loss was significantly (p<0.05) higher for noodles with 20% seaweed puree. Significantly higher water absorption was noticed in noodles with 20% green seaweed puree, which led to softer and spongier textural intensities of the noodles. Although T2 showed lower score for colour values, its overall score for flavour and taste was higher compared to control and other treatments. The results indicate that incorporation of green seaweed puree in noodles has positively influenced the flavour and fibre content and hence, it can be used to enrich the fibre content of noodles.

Published: July 2017

Diet analysis of 1190 fishes belonging to 17 species of deep sea fishes were conducted. The samples were collected from the South-eastern Arabian Sea in bottom trawl by the research vessel FORV Sagar Sampada (cruise no. 322 and 345) during January 2014 and October 2015, between lat. 7- 150N and long. 78 - 720E in the depth range 200 - 1000 m. Diet composition, feeding strength, size range, depth range, distribution and index of preponderance were ascertained for all the species. It was observed that the deep sea fishes mainly feed on benthic and epibenthic organisms such as fishes, shrimps, crabs and squids, revealing their carnivorous nature. Deep sea shrimps are one of the major diet components of these fishes, which is an indication of the availability of good quantity of deep sea shrimps, along the South-eastern Arabian Sea and this abundant population can be commercially utilised in order to lessen the pressure of overexploitation being experienced in case of coastal shrimps.
Arterial line fracture: an unusual complication of invasive blood pressure monitoring
Authors: Allen Lara , Netke Meenu
Published: July 2017

Arterial lines are routinely used for haemodynamic monitoring in critically ill patients and they are associated with a low incidence of major complications. We present a case of radial arterial cannula fracture which necessitated surgical removal. Ultrasound played a crucial role in both identifying the cannula fragment and aiding surgical retrieval. Arterial line fracture is a rare complication of arterial cannulation but patient safety could be improved through a revision of how cannulas are secured to prevent kinking, fatigue and subsequent fracture. We suggest arterial lines should have marked or coloured tips to aid practitioners in ensuring the entire cannula length is removed with the distal tip intact.

Las infecciones de transmisión sexual constituyen un problema epidemiológico y clínico de primer orden en todo el mundo por las secuelas que pueden ocasionar y por sus consecuencias económicas. Los adolescentes y jóvenes, tienen mayor riesgo de presentarlas debido a factores como el inicio temprano de relaciones sexuales, la promiscuidad, entre otros. El objetivo de esta investigación fue determinar los comportamientos de riesgo y nivel de conocimiento de infecciones de transmisión sexual en estudiantes de Bacteriología.  Estudio correlacional de corte transversal. Se aplicó un cuestionario para determinar comportamientos de riesgo y nivel de conocimiento a 128 estudiantes de Bacteriología. El 78,1 % de estudiantes  encuestados si ha tenido relaciones sexuales. El 55 % ingiere bebidas alcohólicas antes de una relación sexual. A través del análisis estadístico se estableció asociación entre la presencia  de ITS con el consumo de drogas (p=0,042). Los estudiantes presentaron un nivel de conocimiento regular. No se encontró asociación estadísticamente significativa entre los comportamientos de riesgo y el nivel de conocimiento (p> 0,05). Los resultados encontrados en esta investigación evidencian la necesidad de realizar actividades tendientes a la prevención y motivar cambios de comportamiento que permitan disminuir el riesgo de contagio de estas enfermedades.

Published: July 2017

Se objetivó revisar la literatura existente respecto a la valoración clínica de la incontinencia urinaria femenina en la consulta ginecológica. Se hizo una exploración de la literatura médica en las bases de datos electrónicas, libros de textos impresos, en revistas indexadas y sociedades científicas reconocidas, a fin de identificar la literatura relevante en la valoración clínica del escape de orina en la consulta ginecológica. En la actualidad la evidencia sobre este tema no permite sugerir un examen clínico específico para valorar la incontinencia en una consulta ginecológica, pero la correlación de hallazgos entre uno y otro, facilita el mismo. La literatura muestra que los métodos de evaluación de clínica de la incontinencia urinaria en la consulta ginecológica, juegan un importante papel en el correcto diagnóstico de las pacientes y en el adecuado tratamiento de las mismas; por lo tanto, se hace necesario volver los ojos a la adecuada evaluación clínica en la consulta ginecológica.
Determinantes para la Práctica de Actividad Física en Estudiantes Universitarios
Authors: Caro-Freile Ana Isabel , Rebolledo-Cobos Roberto Carlos
Published: July 2017

La actividad física hace referencia al movimiento corporal que genera gasto energético, su práctica frecuente mejora las funciones físicas y mentales; el transporte activo, las actividades cotidianas  y la recreación corresponden a la forma más común de actividad física. En Colombia la mayor parte de la población es inactiva, los niños son más activos, pero esta condición disminuye con la edad, el porcentaje de universitarios que realizan actividad física es bajo, está práctica está condicionada por la motivación interna, la condición física, la disponibilidad de tiempo y  el soporte social. El gusto por el deporte, el espíritu competitivo, el mejoramiento de la imagen corporal, el manejo del estrés y los beneficios para la salud son factores motivadores para la práctica de la actividad física en estudiantes universitarios; por otra parte la pereza, el miedo a lesionarse, la escases de escenarios deportivos y la inseguridad del entorno son las barreras más frecuentes para la realización de actividad física en esta población

Synthesis and Biological Evaluations of Organoruthenium Scaffolds: A Comprehensive Update
Authors: Mondal Ashaparna , Paira Priyankar
Published: July 2017

Background:

Currently ruthenium complexes are immerging as effective anticancer agents due to
their less toxicity, better antiproliferative and antimetastatic activity, better stability in cellular environment and
most importantly variable oxidation and co-ordination states of ruthenium allows binding this molecule with a
variety of ligands. So in past few years researchers have shifted their interest towards organoruthenium complexes
having good fluorescent profile that may be applicable for cancer theranostics. Nowadays, photodynamic
therapy has become more acceptable because of its easy and effective approach towards killing cancer
cells.

Objective:

Objective of this review article is to shed light on synthesis, characterization, stability and fluorescence
studies of various ruthenium [Ru(II) and Ru(III)] complexes and different bioactivity studies conducted
with the synthesized compounds to test their candidacy as potent chemotherapeutic agents.

Methods:

Various heterocyclic ligands containing N,O and S as heteroatom mainly were prepared and
subjected to complexation with ruthenium-p-cymene moiety. In most cases [Ru(η6-p-cymene)(µ-Cl)Cl]2 was
used as ruthenium precursor and the reactions were conducted in various alcohol medium such as methanol,
ethanol or propanol. The synthesized complexes were characterized by 1H NMR and 13C NMR spectroscopy,
GC-MS, ESI-MS, elemental analysis and single crystal X-ray crystallography methods. Fluorescence study and
stability study were conducted accordingly using water, PBS buffer or DMSO. Stable compounds were
considered for cell viability studies. To study the efficacy of the compounds in ROS generation as
photosensitizers, in few cases, singlet oxygen quantum yields in presence of light were calculated. Suitable
compounds were selected for in vitro & in vivo antiproliferative, anti-invasive activity studies.

Result:

Many newly synthesized compounds were found to have less IC50 compared to a standard drug cysplatin.
Those compounds were also stable preferably in physiological conditions. Good fluorescence profile
and ROS generation ability were observed for few compounds.

Conclusion:

Numerous ruthenium complexes were developed which can be used as cancer theranostic agents.
Few molecules were synthesized as photosensitizers which were supposed to generate reactive singlet oxygen
species in targeted cellular environment in presence of a particular type of light and thereby ceasing cancer cell
growth.
