Authors: Dekker Travis John , Godin Jonathan Alexander , Dale Kevin , Garrett William E. , Taylor Dean C. , Riboh Jonathan Charles 
Published: July 2017

Objectives: Anterior cruciate ligament (ACL) graft failure and contralateral ACL tears are more frequent in children/adolescents than adults. These re-injuries result in significant time lost from sport, and may contribute to worse long-term outcomes and post-traumatic osteoarthritis. The reasons for higher subsequent injury rates in this unique population are incompletely understood. Methods: We analyzed a single center continuous cohort of patients under the age of eighteen years. Subjects underwent primary ACL reconstruction between 2006 and 2014 with minimum 2-year follow up. Age, sex, graft type, duration of physical therapy, time to return to sport, and length of follow-up were evaluated using multivariable logistic regression modeling to assess their contribution to the risk of subsequent ACL injury. Results: A total of 109 subjects met all study inclusion/exclusion criteria. Eighty-two subjects (75%) had follow-up data and were included in the final analysis. Mean age was 14 +/- 1.9 years (range 8 - 17 years). Mean follow-up was 47.7 +/- 15.6 months (range 28 - 91 months). Seventeen patients (20.7%) sustained an ACL graft rupture, eleven patients (13.4%) sustained a contralateral ACL tear, and one patient (1.2%) sustained both. The combined subsequent injury incidence was 35.4% (29 of 82 subjects). The odds of subsequent ACL injury decreased by 0.29 for every yearly increase in age (OR 0.71, 95% CI 0.53 - 0.92, p = 0.008), and decreased by 0.16 for every monthly increase in time to return to sport (OR 0.84, 95% CI 0.69 - 0.99, p = 0.048). Sex, graft type, duration of physical therapy, sport, and length of follow up did not have a statistically significant impact on the rate of subsequent ACL injury (p > 0.05). Conclusion: Subsequent ACL injuries (ipsilateral or contralateral) are common after primary ACL reconstruction in children and adolescents (combined incidence 35%). Within this high-risk population, younger age and an earlier return to sport portend a higher risk of a second injury.
Short-term Outcomes following Concussion in the NFL: An 11-year Retrospective Study of Player Release Rate and Financial Loss
Authors: Ramkumar Prem , Navarro Sergio Michael 
Published: July 2017

Objectives: The primary goal of this study was to assess the short-term outcomes among National Football League (NFL) players following concussion in terms of: (1) DNP protocol activation, (2) release rate at one and three years, and (3) mean salary reduction. A secondary goal of the study was to stratify the post-concussive release rate by franchise and player position. Methods: NFL player transaction records and publicly available weekly injury reports from August 2005 to January 2016 for NFL players were analyzed. All players immediately sustaining recorded concussions were evaluated for a change to inactive or do-not-play (DNP) status. The one-year and three-year release rate following concussion was defined as any player transitioning to inactivation, retirement, free agency, or any failure to return for a successive season on the same team’s active roster after one or three years from the initial concussion. Student’s t-test was used to compare release rates between non-concussed and concussed players at one and three years. Mean salary reduction per year following concussion was calculated using publicly available player contracts. Additionally, franchise-level and position-based analyses of the release rate were performed. Results: Of the total 5,451 NFL players retrospectively analyzed over the 11-year period, 373 sustained publicly reported concussions resulting in DNP protocol activation. The release rate of the post-concussive versus non-concussive player was 26% vs. 20% at 1 year (p<0.01) and 31% vs. 19% at 3 years (p<0.01). After analyzing individual player contracts, the mean year-over-year change in contract value for concussed players after DNP protocol activation was an overall salary reduction of $760,000/year ± $2,380,000. Figure 1 depicts the tendency of each NFL franchise to release an athlete following concussion within one and three years. Table 1 reports a position-based analysis in terms of concussion rate, mean salary reduction, and NFL career longevity. Conclusion: Our retrospective study demonstrates that NFL concussions resulting in DNP protocol activation leads to a statistically greater release rate among concussed NFL players than non-concussed players. Released players suffered reduction in year-over-year accumulated earnings, and particular franchises tended to release concussed players more than others. [Table: see text]

Preventing Discontinuation of Radiation Therapy: Predictive Factors to Improve Patient Selection for Palliative Treatment
Authors: Puckett Lindsay L. , Luitweiler Eric , Potters Louis , Teckie Sewit 
Published: July 2017

Purpose: Approximately one third of patients with cancer require palliative radiation therapy (PRT), yet no guidelines exist for optimal patient selection. We have observed that many patients who begin PRT do not complete their prescribed treatment. Our study sought to identify factors associated with discontinuation of PRT, assess for a relationship with survival, and inform patient selection. Methods: We performed an institutional review board–approved retrospective analysis of patients with cancer treated in a multicenter radiation oncology department in 2014. Of 297 patients who began PRT, 60 discontinued and 237 completed treatment. Primary end points included discontinuation and overall survival. Results: Patient factors were analyzed for association with discontinuation of PRT and overall survival, respectively, using logistic regression and Cox proportional regression models. Factors associated with discontinuation were low Karnofsky performance status (KPS) score, high number of fractions prescribed, and treatment site other than bone metastasis. The odds of discontinuing PRT decreased by approximately 52% for every 10-point increase in KPS score (odds ratio, 0.48; 95% CI, 0.36 to 0.63; P < .001). Factors associated with shorter survival included discontinuation of PRT, low KPS score, community practice location, multiple comorbidities, and treatment of brain metastases. Patients who discontinued treatment were more likely to die than patients who completed treatment, independent of other factors (hazard ratio, 3.67; 95% CI, 2.41 to 5.61; P < .001). Conclusion: Patients with low KPS scores, long treatment courses, and those treated to sites other than bone metastasis were significantly more likely to discontinue treatment. Discontinuation was predictive for poor survival. Pretreatment evaluation of KPS, comorbidities, and brain metastases can help guide appropriate patient selection for PRT.
Pricing of Conditional Upgrades in the Presence of Strategic Consumers
Authors: Cui Yao , Duenyas Izak , Sahin Ozge 
Published: July 2017

In this paper, we study a conditional upgrade strategy that has recently emerged in the travel industry. After a consumer makes a reservation for a product (e.g., a hotel room), she is asked whether she would like to upgrade her product to a higher-quality (more expensive) one at a discounted price. The upgrade, however, is not fulfilled immediately. The firm fulfills upgrades at check-in if higher-quality products are still available, and the upgrade fee is charged to the consumer if and only if she actually gets upgraded. Consumers decide which product type to book and whether to accept an upgrade offer or not based on the anticipated upgrade probability. We find that conditional upgrades create value by improving demand–supply matching for the firm. The firm can use the conditional upgrade channel to flexibly manage capacity allocations and reoptimize demand segmentation. For a firm that takes product prices as given, offering conditional upgrades is effective in compensating for the firm’s lack of ability in setting prices optimally. For a firm that has the ability to optimize product prices, conditional upgrades generate higher revenues than dynamic pricing.

Published: July 2017

O estudo apresentou como objetivo analisar a distribuição e cobertura do Núcleo de apoio à Saúde da Família (NASF) na IV Macrorregião de saúde do estado de Pernambuco. Foi realizado estudo descritivo de abordagem quantitativa a partir de dados secundários do Cadastro Nacional de Estabelecimentos de Saúde (CNES). Observou-se que as regionais VII, VIII e IX possuem 293 ESF e 32 equipes de NASF nas modalidades 1 e 2. Foi constatada ausência de implantação desse serviço em alguns municípios, bem como excesso de ESF vinculadas em outros. A partir dos dados, observou-se que o número de NASF implantados é insuficiente para apoiar as ESF existentes. Dessa forma, verifica-se que há a necessidade de expansão dessas equipes com vistas a adequação das normas preconizadas pelo Ministério da Saúde.

Published: July 2017

O presente estudo pretende contribuir com as discussões a respeito da necessidade de valorização dos profissionais de educação, principalmente sobre a remuneração dos contratados, especificamente do Município de Ouricuri Pernambuco. O mesmo traz como objetivo identificar os fatores responsáveis pela ocorrência do atraso na remuneração dos profissionais contratados, no âmbito da Secretaria de Educação do referido município. Com a finalidade de alcançar os objetivos propostos foi realizado entrevistas com os gestores onde constatou - se vários motivos que influenciam na gestão financeira causando irregularidade no pagamento de professores contratados. De acordo com a pesquisa, conclui - se que uma das causas do atraso das folhas de pagamento esta relacionado aos repasses do governo federal, pois o município não dispõe de recurso suficiente e depende da complementação da verba federal. Outro motivo e a não realização de concurso público que provoca uma demanda de contratos temporários e consequentimente influencia no atraso do pagamento. Como solução para o problema foi apontada a realização do concurso público que segundo a opinião dos entrevistados sendo os profissionais concursados o repasse do governo federal fica assegurado para complementar à folha de pagamento dos servidores.

This thesis deals with a study on the torsional stiffness of existing truck chassis and some others improved models by using finite element method. The objective of this study is to improve the torsional stiffness by design and to provide simulation of the deflection on the chassis. The problem on the chassis is the deflection on the chassis whereas higher displacement will affect the torsional stiffness of the truck. ABAQUS was used as it is a powerful engineering simulation tool based on the finite element method. The magnitude of torsional stiffness for existing and modified models were calculated based on data of deflection of each models which were obtained from the finite element simulation. The multi holes model was choosen as the best proposed model due to the highest of torsional stffness as comparison result among existing and modified models.

Development of composite materials is growing rapidly to support medical needs. Biocomposite was made from bovine bone powder/shellac/chitosan for bone filler applications. Biocomposite of BHA(Bovine Hydroxyapatite)/shellac/chitosan was derived of bovine bone powder coated with shellac 10 ml. Mixed variation between BHA/shellac and chitosan i.e 30:40, 40:60, 50:50, 60:40, 70:30 %wt were synthesized by dry method. Samples of BHA/shellac/chitosan were compacted with the pressure 60 bar until becomes solid with the cylinder mold 13 mm and 8 mm in thickness, the calcination process on temperature of 900ºC for 2 hours and increased temperature is 10ºC/min. Test XRD (X-Ray Diffraction), Microvickers, DTS (Diametric Tensile Strength) and SEM (Scanning Electron Microschopy), Density, and Porosity. XRD test results showed that bovine powder has become BHA (Bovine Hydroxyapatite), microvickers test of sample BHA/shellac/chitosan for maximum was 7.47 ± 0.685 VHN and 0.182 ± 3.73 VHN for minimum, DTS test of sample BHA/shellac/chitosan maximum at 36.66 ± 9.01 KPa and minimum at 13.90 ± 1.24 KPa. Porous observations with SEM toward sample BHA/shellac/chitosan porous size and number of samples contained at BHA/shellac/chitosan is 70:30 wt%. Density test with highest value was 1,168gr/cm3, and lowest 1,070 gr/cm3. Highest porosity value at variation 50/50 %wt = 0,988%, and the lowest at 70/30 %wt = 0,977%

Authors: Sánchez-Salazar José , Aymerich-Sánchez Edward 
Published: July 2017

Debido a que la tendencia actual es tener más y más procesadores (cores) disponibles en cada computadora, la escalabilidad de las estructuras de datos usadas en programación paralela debe ser considerada cuidadosamente, para así garantizar que ellas saquen ventaja de los procesadores disponibles. Debido al aumento en la contención, usualmente las estructuras de datos basadas en bloqueos no mejoran su rendimiento proporcionalmente al incrementar el número de procesadores. El uso de estructuras de datos libres de bloqueos bien diseñadas, tales como las colas first in-first out, puede mejorar el rendimiento de un programa paralelo, cuando hay varios procesadores disponibles. En este trabajo se diseña e implementa una versión paralela de bzip2, un programa para compresión y descompresión de datos muy popular, usando colas libres de bloqueos en lugar de las basadas en bloqueos, y aplicando una estrategia de dos buffers de salida. Se compara el rendimiento de la implementación libre de bloqueos contra implementaciones basadas en bloqueos. Se midió el tiempo de compresión usando diferente número de procesadores y diferentes tamaños de bloques. Coincidiendo con la hipótesis de trabajo, los resultados muestran que la implementación paralela libre de bloqueos supera las otras implementaciones.

Introdução: A medida da circunferência braquial é uma das etapas a serem realizadas antes do procedimento de medida indireta da pressão arterial. No entanto, observa-se na prática uma quebra neste protocolo, o que pode levar a valores e diagnósticos incorretos.Objetivo: Identificar a circunferência braquial de pacientes internados e correlacionar com o tamanho de manguito correspondente, de acordo com as VI Diretrizes Brasileiras de Hipertensão. Materiais e Métodos: Estudo transversal realizado com pacientes internados em unidade de terapia intensiva adulto. Utilizou-se fita métrica inelástica para medir a circunferência braquial dos sujeitos e compará-la com as recomendações das VI Diretrizes Brasileiras de Hipertensão.Resultados: Foram medidas as circunferências braquiais de 46 pacientes. Destes, apenas 16 (34,8%) estavam com manguitos apropriados, 28 (60,9%) com maiores que o adequado e dois deles (4,3%) com um cuff menor do que o preconizado.Conclusão: Os resultados do estudo mostram inadequação na escolha dos manguitos, o que pode ter privado pacientes de tratamentos corretos perante o quadro clinico. É pontual a necessidade de atividades de educação continuada para os profissionais envolvidos com a medida da pressão arterial, especialmente em relação à adequação do manguito em pacientes críticos.

Objetivo: Analisar a quantidade de gestantes com queixa de lombalgia gestacional, as características da dor relatada, identificar o impacto nas atividades de vida diária e relacionar o grau de incapacidade funcional com a qualidade de vida em gestantes do primeiro e segundo trimestres gestacionais.Materiais e Métodos: Estudo observacional descritivo, do tipo transversal, realizado com gestantes atendidas em uma Maternidade do município de Lagarto/SE. Para avaliação da incapacidade provocada pela lombalgia utilizou-se o questionário de Roland-Morris e para avaliação da qualidade de vida o Medical Outcomes Study-36.Resultados: A amostra foi dividida nos grupos primeiro (GI; n=19) e segundo trimestre gestacional (GII; n=19). A prevalência de lombalgia foi 84,2% GI e 78,9% GII (p=0,334). A dor teve inicio durante a gestação em 75% no GI e 73,3% no GII (p=0,784). Quanto aos fatores que agravavam a dor, 62,5% no GI e 33,3% no GII relataram ficar na mesma posição. Para diminuir a dor, o repouso foi o mais citado nos dois grupos (p<0,001). No questionário Roland-Morris, a média do escore total foi 7,16±4,80 para o GI e 7,79±5,55 GII. Na avaliação da qualidade de vida, os domínios mais afetados negativamente foram à vitalidade no GI (51,32±21,27) (p=0,484) e limitação por aspectos emocionais no GII (52,63±43,48) (p=0,623). Os menos afetados foram capacidade funcional no GI (70±29,11) (p=0,784) e aspectos sociais no GII (73,68±32,78) (p=0,661).Conclusão: A lombalgia gestacional atinge principalmente mulheres jovens e primigestas, interfere na vitalidade e aspectos emocionais, gerando impacto nas atividades de vida diárias. No entanto, a dor não torna as mulheres incapacitantes durante os dois primeiros trimestres gestacionais.

Abstract: Following tooth removal, three dimensional hard- and soft-tissue loss take place. Spontaneous healing makes the defect more severe and results in collapsing tissues. Implant placement is not feasible. In the aestethic zone even fixed partial dentures will not deliver the expected result. Our aim was to demonstrate that only ridge preservation enables implant placement and also provides excellent aestetic result even at frontal areas. CBCT was made before and 6–8 months after ridge preservation. Vertical and socket area measurements were carried out and compared in pre-, and postoperative images. Implant placement was feasible in all three cases; furthermore favourable buccal bone (4.24 mm, 6.22 mm, 9.57 mm) and area growth (129%, 145%, 167%) were measured. Ridge preservation provides appropriate therapy for complete reconstruction of tissues after tooth removal. Orv Hetil. 2017; 158(31): 1228–1234.
