Authors: Navarro Ibarra Lizzeth Aurora , Cuevas Salazar Omar , Martínez Castillo Jaime
Published: April 2017

La finalidad de la investigación es hacer un meta-análisis del estado del conocimiento de la educación mediada por las Tecnologías de la Información y Comunicación (TIC) en México y América Latina en la última década. Previo a la búsqueda de información se definieron Líneas Generales de Aplicación del Conocimiento (LGAC) y categorías. Los resultados indican que los estudios están orientados principalmente a los recursos virtuales de aprendizaje y su contribución en la educación. De igual forma se detectó que el 80% de los trabajos son de tipo cualitativo, siendo los de corte cuantitativo o mixto sólo una quinta parte. La educación superior es hacia donde se dirige el 46% de las investigaciones en México y el 62% en América Latina. Se encontraron vacíos en la generación de conocimiento en las habilidades digitales de los padres, capacitación a estudiantes sobre competencias en TIC, vinculación educativa con empresas y educación a discapacitados.
Estratificación digital: acceso y usos de las TIC en la población escolar chilena
Authors: Rodríguez Garcés Carlos René , Sandoval Muñoz Daniela
Published: April 2017

Las TIC ocupan en la actualidad un importante espacio en la vida cotidiana, pues son utilizadas en diversos contextos y con diferentes finalidades; no obstante, existe un sector de la población excluido de las oportunidades que las TIC brindan, exclusión determinada por el nivel socioeconómico. Utilizando bases de datos nacionales, en la presente investigación se hace un análisis descriptivo-correlacional de la penetración y usos de las TIC en la población escolar de enseñanza básica y media en Chile. Los resultados indican que el acceso a Internet y a las tecnologías está fuertemente segmentado; la estratificación digital va más allá del acceso y existen usos diferenciados con base en el capital cultural del estudiante. La escuela se configura como el principal elemento compensador de la brecha digital posibilitando el acceso (aunque restringido) a las TIC para una proporción importante de estudiantes de los sectores de menores ingresos.

La Política de Cohesión Europea en dos regiones españolas: configurando las redes de políticas y el capital social
Authors: Jordana Jacint , Mota Fabiola , Noferini Andrea
Published: April 2017

El artículo analiza la fase de programación de la política europea de cohesión centrándose en el nivel autonómico de gobierno. Sostiene que los Fondos Estructurales han afectado de manera esencial la configuración de las políticas de desarrollo regional. En particular, la europeización de la política regional en España ha implicado un papel creciente de los gobiernos autonómicos, que han ido adoptando un conjunto de prácticas y procedimientos homogéneos en los procesos de programación e implementación de la política de cohesión. No obstante, la evidencia empírica recogida en las comunidades autónomas de Galicia y de Murcia, en relación con la programación del período financiero 2007-2013 (PORs), prueba la existencia de diferentes configuraciones de la red de política regional que lleva a cabo las tareas de programación. Al mismo tiempo, también las características de capital social de los actores implicados en cada red de política regional presentan diferencias significativas. Estos resultados sugieren que, a pesar de que los procedimientos formales de programación son prácticamente idénticos, los procesos políticos son bastante distintos en cada comunidad autónoma, lo que plantea nuevos interrogantes sobre las causas de dichas variaciones.

A spinal epidural abscess due to Streptobacillus moniliformis infection following a rat bite: case report
Authors: Hammer Alexander , Wolff Dorit , Geißdörfer Walter , Schrey Michael , Ziegler Renate , Steiner Hans-Herbert , Bogdan Christian
Published: April 2017

The authors describe the case of a 40-year-old man suffering from an epidural abscess in the thoracic spine due to a rarely isolated pathogen, Streptobacillus moniliformis, the causative agent of rat bite fever. Besides diffuse abdominal pain, ataxia, paresthesia, hypesthesia, and enhanced reflexes of the lower extremities, the patient suffered from a decreased sensation of bladder filling. His history was also positive for a rat bite 6 weeks earlier. Magnetic resonance imaging showed an epidural, space-occupying lesion compressing the spinal cord at the vertebral levels of T6–8. Neurosurgery revealed an epidural abscess, which was drained via laminectomy (T-7) and excision of the ligamentum flavum (T6–8). The etiological agent S. moniliformis was identified by 16S rRNA-based polymerase chain reaction and sequencing as well as by culture and mass spectrometry. Treatment with penicillin G led to complete resolution of the abscess and clinical recovery of the patient, who regained his bladder-filling sensation and free walking ability.

This case demonstrates that careful attention to the patient's history is essential in suspecting unusual bacterial pathogens as the cause of an epidural abscess and initiating the optimal diagnostic procedure and antimicrobial therapy.
Minimally invasive instrumentation without fusion during posterior thoracic corpectomies: a comparison of percutaneously instrumented nonfused segments with open instrumented fused segments
Authors: Lau Darryl , Chou Dean
Published: April 2017

OBJECTIVE

During the mini-open posterior corpectomy, percutaneous instrumentation without fusion is performed above and below the corpectomy level. In this study, the authors' goal was to compare the perioperative and long-term implant failure rates of patients who underwent nonfused percutaneous instrumentation with those of patients who underwent traditional open instrumented fusion.

METHODS

Adult patients who underwent posterior thoracic corpectomies with cage reconstruction between 2009 and 2014 were identified. Patients who underwent mini-open corpectomy had percutaneous instrumentation without fusion, and patients who underwent open corpectomy had instrumented fusion above and below the corpectomy site. The authors compared perioperative outcomes and rates of implant failure requiring reoperation between the open (fused) and mini-open (unfused) groups.

RESULTS

A total of 75 patients were identified, and 53 patients (32 open and 21 mini-open) were available for followup. The mean patient age was 52.8 years, and 56.6% of patients were male. There were no significant differences in baseline variables between the 2 groups. The overall perioperative complication rate was 15.1%, and there was no significant difference between the open and mini-open groups (18.8% vs 9.5%; p = 0.359). The mean hospital stay was 10.5 days. The open group required a significantly longer stay than the mini-open group (12.8 vs 7.1 days; p < 0.001). Overall implant failure rates requiring reoperation were 1.9% at 6 months, 9.1% at 1 year, and 14.7% at 2 years. There were no significant differences in reoperation rates between the open and mini-open groups at 6 months (3.1% vs 0.0%, p = 0.413), 1 year (10.7% vs 6.2%, p = 0.620), and 2 years (18.2% vs 8.3%, p = 0.438). The overall mean follow-up was 29.2 months.

CONCLUSIONS

These findings suggest that percutaneous instrumentation without fusion in mini-open transpedicular corpectomies offers similar implant failure and reoperation rates as open instrumented fusion as far out as 2 years of follow-up.

Published: April 2017

OBJECTIVE

The ability to assess the risk of adverse events based on known patient factors and comorbidities would provide more effective preoperative risk stratification. Present risk assessment in spine surgery is limited. An adverse event prediction tool was developed to predict the risk of complications after spine surgery and tested on a prospective patient cohort.

METHODS

The spinal Risk Assessment Tool (RAT), a novel instrument for the assessment of risk for patients undergoing spine surgery that was developed based on an administrative claims database, was prospectively applied to 246 patients undergoing 257 spinal procedures over a 3-month period. Prospectively collected data were used to compare the RAT to the Charlson Comorbidity Index (CCI) and the American College of Surgeons National Surgery Quality Improvement Program (ACS NSQIP) Surgical Risk Calculator. Study end point was occurrence and type of complication after spine surgery.

RESULTS

The authors identified 69 patients (73 procedures) who experienced a complication over the prospective study period. Cardiac complications were most common (10.2%). Receiver operating characteristic (ROC) curves were calculated to compare complication outcomes using the different assessment tools. Area under the curve (AUC) analysis showed comparable predictive accuracy between the RAT and the ACS NSQIP calculator (0.670 [95% CI 0.60–0.74] in RAT, 0.669 [95% CI 0.60–0.74] in NSQIP). The CCI was not accurate in predicting complication occurrence (0.55 [95% CI 0.48–0.62]). The RAT produced mean probabilities of 34.6% for patients who had a complication and 24% for patients who did not (p = 0.0003). The generated predicted values were stratified into low, medium, and high rates. For the RAT, the predicted complication rate was 10.1% in the low-risk group (observed rate 12.8%), 21.9% in the medium-risk group (observed 31.8%), and 49.7% in the high-risk group (observed 41.2%). The ACS NSQIP calculator consistently produced complication predictions that underestimated complication occurrence: 3.4% in the low-risk group (observed 12.6%), 5.9% in the medium-risk group (observed 34.5%), and 12.5% in the high-risk group (observed 38.8%). The RAT was more accurate than the ACS NSQIP calculator (p = 0.0018).

CONCLUSIONS

While the RAT and ACS NSQIP calculator were both able to identify patients more likely to experience complications following spine surgery, both have substantial room for improvement. Risk stratification is feasible in spine surgery procedures; currently used measures have low accuracy.
Hydrocephalus treatment in children: long-term outcome in 975 consecutive patients
Authors: Beuriat Pierre-Aurelien , Puget Stephanie , Cinalli Giuseppe , Blauwblomme Thomas , Beccaria Kevin , Zerah Michel , Sainte-Rose Christian
Published: April 2017

OBJECTIVE

Hydrocephalus remains one of the more common pathologies managed in pediatric neurosurgical units. Endoscopic third ventriculostomy (ETV) has an advantage over ventriculoperitoneal shunting as it enables patients to remain device free. Multiple shunt devices with various valve designs exist, with no one valve proven to be superior to another. The aim of this study was to describe the management of hydrocephalus and its long-term outcome.

METHODS

The authors retrospectively reviewed the medical records of all patients who had been treated for hydrocephalus at the Hôpital Necker-Enfants Malades in the period from 1985 to 1995.

RESULTS

Nine hundred seventy-five children had been treated for hydrocephalus. The mean follow-up was 11 ± 7.4 years (mean ± standard deviation). The most common cause of hydrocephalus was tumor related (32.3%), followed by malformative (24.5%) and inflammatory (20.9%) causes. Two hundred eighty patients underwent ETV as the first-line treatment. The procedure was effective in controlling hydrocephalus due to posterior fossa tumors and aqueductal stenosis. Six hundred ninety-five children had initial shunt insertion, with the majority receiving an Orbis-Sigma valve (OSV). The overall OSV shunt survival was 70% at 1 year, 58% at 10 years, and 49% at 20 years. The most common cause for mechanical shunt failure was obstruction (50.7%). Overall shunt survival was statistically different between the OSV and the differential-pressure valve (p = 0.009).

CONCLUSIONS

Endoscopic third ventriculostomy is effective in the management of childhood hydrocephalus. Its success is directly related to the underlying pathology. In the long term, the OSV has significantly higher event-free shunt survival than the classic differential-pressure valve systems
Effect of Nest Characteristics on Thermal Properties, Clutch Size, and Reproductive Performance for an Open-Cup Nesting Songbird
Authors: Akresh Michael E. , Ardia Daniel R. , King David I.
Published: April 2017

Maintaining avian eggs and young at optimum temperatures for development can increase hatching success and nestling condition, but this maintenance requires parental energetic demands. Bird nests, which often provide a structure to safely hold the eggs and nestlings and protect them from predators, can additionally be designed to help maintain eggs’ optimum temperatures by minimising heat loss, especially in climates where eggs cool rapidly when unattended. We collected and measured Prairie Warbler ( Setophaga discolor) nests in western Massachusetts, U.S. in 2009 and conducted a climate-controlled, nest-cooling experiment to determine how nest characteristics affect thermal properties for small, open-cup nesting birds. We then assessed if nests with better insulation properties resulted in any fitness benefits, and also tested if nest structural characteristics affected birds’ fitness. We found that nest characteristics influenced their thermal properties, with thicker, heavier, and larger nests having slower cooling rates and higher predicted equilibrium egg temperatures. Both nest cup depth and clutch size significantly declined over the breeding season, and we observed a trend, although non-significant, that nests with shallower cups had smaller clutches. Contrary to studies on cavity-nesting birds, we found no significant effects of nest thermal properties or nest structure on hatching and fledging success, nestling condition, brood parasitism, or nest survival. Prairie Warblers in our study site may already be adapted to build nests within a range that maximises their fitness. Furthermore, studies have shown that open-cup nests of other species are relatively thicker and more insulated in colder environments at higher latitudes than our study. Instead of building nests to solely minimise heat loss, open-cup nesting birds in temperate climates may also be driven by opposing selection pressures when building their nests, such as to prevent nestlings from overheating during hot days.
Diet-ESP: IP layer security for IoT
Authors: Migault Daniel , Guggemos Tobias , Killian Sylvain , Laurent Maryline , Pujolle Guy , Wary Jean Philippe
Published: April 2017

The number of devices connected through the Internet of Things (IoT) will significantly grow in the next few years while security of their interconnections is going to be a major challenge. For many devices in IoT scenarios, the necessary resources to send and receive bytes are extremely high and when such devices are powered with battery the amount of exchanged bytes directly impacts their life time. As a result, compression of existing protocols is a widely accepted technique to make IoT benefit from the protocols developed over the last decades.

This paper presents ESP Header Compression (EHC), a framework that enables compression of packets protected with Encapsulating Security Payload (ESP). EHC is composed of EHC Rules, targeting the compression of a specific field and organized according to EHC Strategies. Further, the paper presents Diet-ESP, an EHC Strategy that highly reduces the networking overhead of ESP packets to address the IoT security and bandwidth requirements. Diet-ESP results in sending fewer bytes which in turn reduces the number of required radio frames and thus battery consumption. The measurements showed that sending 10 byte application data on IEEE 802.15.4 radio networks secured with the standard ESP requires sending an additional frame. This results into a 95% energy overhead compared to the unprotected data, while Diet-ESP results only in a 3% overhead compared to unprotected data.

This small overhead is achievable with some compressions being performed within the ESP stack which requires altering the same. Nevertheless, Diet-ESP remains fully security compliant to ESP and performs better than any other compression framework as far as ESP is considered.
Sarcomere Dysfunction in Nemaline Myopathy
Authors: de Winter Josine M. , Ottenheijm Coen A.C.
Published: April 2017

Nemaline myopathy (NM) is among the most common non-dystrophic congenital myopathies (incidence 1:50.000). Hallmark features of NM are skeletal muscle weakness and the presence of nemaline bodies in the muscle fiber. The clinical phenotype of NM patients is quite diverse, ranging from neonatal death to normal lifespan with almost normal motor function. As the respiratory muscles are involved as well, severely affected patients are ventilator-dependent. The mechanisms underlying muscle weakness in NM are currently poorly understood. Therefore, no therapeutic treatment is available yet.

Eleven implicated genes have been identified: ten genes encode proteins that are either components of thin filament, or are thought to contribute to stability or turnover of thin filament proteins. The thin filament is a major constituent of the sarcomere, the smallest contractile unit in muscle. It is at this level of contraction – thin-thick filament interaction – where muscle weakness originates in NM patients.

This review focusses on how sarcomeric gene mutations directly compromise sarcomere function in NM. Insight into the contribution of sarcomeric dysfunction to muscle weakness in NM, across the genes involved, will direct towards the development of targeted therapeutic strategies.

Background: Treatment outcomes are poorly characterized in patients with metastatic chromophobe renal cell cancer (chrRCC), a subtype of renal cell carcinoma.

Objective: This retrospective series aims to determine metastatic chrRCC treatment outcomes in the targeted therapy era.

Methods: A retrospective data analysis was performed using the IMDC dataset of 4970 patients to determine metastatic chrRCC treatment outcomes in the targeted therapy era.

Results: 109/4970 (2.2%) patients had metastatic chrRCC out of all patients with mRCC treated with targeted therapy. These patients were compared with 4861/4970 (97.8%) clear cell mRCC (ccRCC) patients. Patients with metastatic chrRCC had a similar OS compared to patients with ccRCC (23.8 months (95% CI 16.7 – 28.1) vs 22.4 months (95% CI 21.4 – 23.4), respectively ( p = 0.0908). Patients with IMDC favorable (18%), intermediate (59%) and poor risk (23%) had median overall survivals of 31.4, 27.3, and 4.8 months, respectively ( p = 0.028).

Conclusions: To the authors’ knowledge, this is the largest series of metastatic chrRCC patients and these results set new benchmarks for survival in clinical trial design and patient counseling. The IMDC criteria risk categories seem to stratify patients into appropriate favourable, intermediate, and poor risk groups, although larger patient numbers are required. It appears that outcomes between metastatic chrRCC and ccRCC are similar when treated with conventional targeted therapies. Patients with metastatic chrRCC can be treated with tyrosine kinase inhibitors and enrolled in clinical trials to further measure outcomes in this rare patient population.

The objective of this study was to purify and characterize the alpha-N-acetylgalactosaminidase (?-GalNAcase) from hilsha fish, Hilsha ilisha. Digestive organ of hilsha fish was found to contain a large amount of ?-GalNAcase in compared with the other tissues examined. ?-GalNAcase was purified from the crude extract of hilsha fish by ammonium sulphate precipitation, Sephadex G-200 gel filtration, and SP-Sephadex C-50 column chromatography. The purified enzyme gave a single band on sodium dodecylsulphate-polyacrylamide gel electrophoresis and exhibited a molecular mass of 48 kDa. The final preparation of ?-GalNAcase showed 3.02% ?-galactosidase activity. The enzyme had an optimum pH of 4.0 and was found to be quiet heat stable at 37°C. Inhibition studies with metal ions demonstrated that the enzyme was highly inhibited by silver and mercury ions. Both N-acetylgalactosamine and galactose affect the enzyme activity. Kinetic studies with the enzyme showed that the KM value for p-nitrophenyl-?-N-acetylgalactosaminide substrate was 3.31 mM and the Vmax value was 35.04 unit/mg.

Published: April 2017

Effective and cost efficient wastewater treatment is one of the major challenges for textile sectors of Bangladesh. The present study was an attempt to address the removal efficiency of organic matter and suspended solid of textile waste water by industrial scale combined anaerobic and aerobic treatment system. The experiments were performed at 6, 12, 18 and 24 hr hydraulic retention times (HRTs) and removal efficiency of different parameters (BOD5, COD and TSS) was measured. The average BOD5 and COD removal efficiency were in the range of 71% to 91% and 52% to 75% respectively at different HRTs in this plant. 73% - 82% range of TSS of wastewater was reduced by this method. Maximum BOD5 (88.2-92.5%) removal was occurred in aerobic treatment system whereas, high amount of COD (49.2-71.7%) removal efficiency reported in the anaerobic treatment system at different HRTs. The result indicated that the industrial scale combined treatment system can treat wastewater effectively.

Hanging, the commonest method of suicide, is a form of violent asphyxia produced by suspending the body with a ligature round the neck. A total of 312 cases of suicidal hanging autopsied in this five years retrospective descriptive study spanning from January 2000 to December 2004 at Sir Salimullah Medical College (SSMC) morgue. The objective of this study was to evaluate the present situation, pattern of hanging, socio-demographic characteristics of victims and probable cause of suicidal hanging of studied population. Victims' mean( ± SD) age was (23.5 ± 11.7) years and highest number 146 (46.8%) of victims were from the age group 21-30 years. This study revealed that numbers of suicidal hanging cases were increasing day by day in the studied area (46 in 2000 and 82 in 2004). Out of 312 cases, 171 (55%) were female and 141 (45%) were male. Married cases were 165 (53%) and 204 (66%) victims hanged themselves at night. In 165 (53%) victims' stomach were found empty. Most of the cases 309 (99%) were complete hanging and majority 299 (96%) of the bodies were recovered from the living rooms. In two hundred and sixty nine (87%) cases had ligature mark at neck, 132 (43%) cases had fracture of hyoid bone and 45 (15%) victims had the fracture of thyroid cartilages and none of the victims had found spinal cord injury. Maximum number of victims 134 (43%) used ropes as ligature materials. Most common known 70 (23%) cause of self-suspension was quarrel between husband and wife.KYAMC Journal Vol. 4, No.-1, July 2013, Page 331-336

Health Paradox of Indigenous people in Bangladesh: Unravelling aspects of mass media campaigns in changing health behaviors to prevent non-communicable diseases
Authors: Tabassum Reshman
Published: April 2017

Bangladesh, a developing country, has one of the highest rates of age-standardized mortality due to non-communicable diseases (NCDs). The prevalence of NCDs is steadily increasing within all population groups, including indigenous communities in Bangladesh. Indigenous people, non-dominant communities of society, are individuals having distinctive social, economic or political systems, and preserving own languages, cultures and beliefs. Contemporary research proposes that negative health behaviors, especially tobacco use, unhealthy diets, physical inactivity, and alcohol consumption are becoming escalating problems in Bangladesh. Indigenous communities with low health literacy are less receptive to health information and are unlikely to embrace positive health behaviors. Three major barriers to change health behaviors toward preventing NCDs among indigenous people in Bangladesh are: unawareness of the severity and/or importance of NCDs; absence of health literacy or knowledge on NCDs; and lack of advocacy for health intervention programs for indigenous patients suffering from NCDs. Intertwined within socio-economic delusions and discrepancies, indigenous people miss out on health care to prevent NCDs. Mass media campaigns have both an extensive coverage and an awareness-constructing potential to educate and influence intended audiences attitudes on changing health related behaviors. Bangladesh can change health behaviors within indigenous communities by adopting some effective strategies, including using multifaceted mass media to intensify coverage of the health campaigns, underpinning stereotyping health beliefs and conveying unidentified details about NCDs, and developing risk-reduction strategies for indigenous patients suffering from NCDs. Multi-stakeholder and intergovernmental mechanisms and mass media campaigns can be effective options for changing health behaviors of indigenous people in Bangladesh.South East Asia Journal of Public Health Vol.6(2) 2016: 17-22

Improved Tensor-Based Singular Spectrum Analysis Based on Single Channel Blind Source Separation Algorithm and Its Application to Fault Diagnosis
Authors: Yang Dan , Yi Cancan , Xu Zengbin , Zhang Yi , Ge Mao , Liu Changming
Published: April 2017

To solve the problem of multi-fault blind source separation (BSS) in the case that the observed signals are under-determined, a novel approach for single channel blind source separation (SCBSS) based on the improved tensor-based singular spectrum analysis (TSSA) is proposed. As the most natural representation of high-dimensional data, tensor can preserve the intrinsic structure of the data to the maximum extent. Thus, TSSA method can be employed to extract the multi-fault features from the measured single-channel vibration signal. However, SCBSS based on TSSA still has some limitations, mainly including unsatisfactory convergence of TSSA in many cases and the number of source signals is hard to accurately estimate. Therefore, the improved TSSA algorithm based on canonical decomposition and parallel factors (CANDECOMP/PARAFAC) weighted optimization, namely CP-WOPT, is proposed in this paper. CP-WOPT algorithm is applied to process the factor matrix using a first-order optimization approach instead of the original least square method in TSSA, so as to improve the convergence of this algorithm. In order to accurately estimate the number of the source signals in BSS, EMD-SVD-BIC (empirical mode decomposition—singular value decomposition—Bayesian information criterion) method, instead of the SVD in the conventional TSSA, is introduced. To validate the proposed method, we applied it to the analysis of the numerical simulation signal and the multi-fault rolling bearing signals.
