Published: March 2018

BACKGROUND:
Although the utility of universal newborn hearing screening is undisputed, testing protocols vary. In particular, the impact of the infant’s age at the time of automated auditory brainstem response (AABR) screening has not been well studied.

METHODS:
We conducted a retrospective review of newborn hearing screening data in 6817 low-risk, term and late-preterm newborns at our large, urban, academic medical center for a 1-year period to analyze the impact of age and other factors on the screening failure rate and referral for diagnostic testing.

RESULTS:
AABR screening failure rates decreased with postnatal age over the first 48 hours; 13.3% failed at &lt;24 hours versus 3.8% at ≥48 hours (P &lt; .0001). Infants who were initially tested at ≥36 hours failed repeat testing more often than those who were tested at &lt;36 hours (11.5% vs 18.9%; P = .03). Other factors that were associated with failure included being a boy and of a race other than white. Sensorineural hearing loss (SNHL) was diagnosed in 18.6% of infants who failed their final screening at ≥48 hours compared with 2.8% of those whose final screening occurred earlier (P = .03). SNHL was more likely in infants who failed their first screening bilaterally (21.2%) than unilaterally (4.4%); P = .03).

CONCLUSIONS:
Among healthy newborns, delaying AABR screening in the first 48 hours minimized failure rates. SNHL was 6 times as likely in infants who failed their final screening at ≥48 hours compared with those who were screened at &lt;48 hours of age. In our study, we offer guidance for nursery directors and audiologists who determine hearing screening protocols and counsel families about results.

BACKGROUND:Fever of unknown origin (FUO) is a well-known pediatric presentation. The primary studies determining the causes of prolonged fever in children were performed 4 decades ago, before major advances in laboratory and diagnostic testing. Given that the distribution of diagnosed causes of adult FUO has changed in recent decades, we hypothesized that the etiology of FUO in children has concordantly changed and also may be impacted by a definition that includes a shorter required duration of fever.METHODS:A single-center, retrospective review of patients 6 months to 18 years of age admitted to the North Carolina Children’s Hospital from January 1, 2002, to December 21, 2012, with an International Classification of Diseases, Ninth Revision diagnosis of fever, a documented fever duration &gt;7 days before admission, and a previous physician evaluation of each patient’s illness.RESULTS:A total of 1164 patients were identified, and of these, 102 met our inclusion criteria for FUO. Etiologic categories included “infectious” (42 out of 102 patients), “autoimmune” (28 out of 102 patients), “oncologic” (18 out of 102 patients), and “other” or “unknown” (14 out of 102 patients). Several clinical factors were statistically and significantly different between etiologic categories, including fever length, laboratory values, imaging performed, length of stay, and hospital costs.CONCLUSIONS:Unlike adult studies, the categorical distribution of diagnoses for pediatric FUO has marginally shifted compared to previously reported pediatric studies. Patients hospitalized with FUO undergo prolonged hospital stays and have high hospital costs. Additional study is needed to improve the recognition, treatment, and expense of diagnosis of prolonged fever in children.

Published: March 2018

BACKGROUND:
Addressing anthropometric failure in low- and middle-income countries can have 2 targets of inference: addressing differences between individuals within populations (Wpop) or differences between populations (Bpop). We present a multilevel framework to apply both targets of inference simultaneously and quantify the extent to which variation in anthropometric status and growth failure is reflective of undernourished children or undernourished populations.

METHODS:
Cross-sectional data originated from the Demographic and Health Surveys program, covering children under age 5 from 57 countries surveyed between 2001 and 2015.

RESULTS:
A majority of variation in child anthropometric status and growth failure was attributable to Wpop-associated differences, accounting for 89%, 83%, and 85% of the variability in z scores for height for age, weight for age, and weight for height. Bpop-associated differences (communities, regions, and countries combined) were associated with 11%, 17%, and 15% of the variation in height-for-age z score, weight-for-age z score, and weight-for-height z score. Prevalence of anthropometric failure was closely correlated with mean levels of height and weight. Approximately 1% of Wpop variability, compared with 30% to 50% of the Bpop variability, was explained by mean values of maternal correlates of anthropometric status and failure. Although there is greater explanatory power Bpop, this varied because of modifiability of what constitutes population.

CONCLUSIONS:
Our results suggest that universal strategies to prevent future anthropometric failure in populations combined with targeted strategies to address both the impending and existing burden among children are needed.
Effect of Processing on Nix-Gao Bilinear Indentation Results Obtained for High Purity Iron
Authors: Soman Prasad Pramod , Herbert Erik Gregory , Aifantis Katerina E. , Hackney Stephen A. 
Published: March 2018

AbstractInstrumented indentation of a high purity Fe surface with unresolved surface deformation due to mechanical polishing is compared to the same grain surface annealed at increasing time and temperature. The differences in indentation size effect behavior with annealing are correlated with hardness and electron backscatter diffraction measurements as independent measures of surface layer deformation. It is found that the Nix Gao plot evolves from non-linear (bilinear) towards the predicted linear relationship as the surface deformation is removed. The experimental observations are rationalized by inclusion of a depth dependent, polishing induced forest dislocation density within the Nix-Gao model.
Density Functional Theory study of Cu doped {0001} and {01$\overline 1 $2} surfaces of hematite for water splitting

Published: March 2018

AbstractDensity Functional Theory (DFT) calculations study of Cu doped {0001} and {01–12} surfaces of hematite for enhanced water splitting have been carried out. The doping was restricted to planes in the vicinity of the surface, specifically from the top most layers to the third inner layer of Fe atoms. Thermodynamic stabilities were evaluated based on surface energies and formation energies. The evaluation of thermodynamic stabilities (negative formation energy values) shows that the systems are thermodynamically stable which suggest that they can be synthesized in the laboratory under favorable conditions. Doping on the top most layer yields the energetically most favorable structure. The calculated charge density difference plots showed the concentration of charge mainly at the top of the surface (termination region), and this charge depleted from the Cu atom to the surrounding Fe and O atoms. This phenomenon (concentration of charge at the top of the surface) is likely to reduce the distance moved by the charge carriers, decrease in charge recombination leading to facile transfer of charge to the adsorbate and, suggesting improved photoelectrochemical water oxidation activity of hematite. The analysis of electron electronic structure reveals that Cu doped surface systems does not only decrease the band gap but also leads to the correct conduction band alignment for direct water splitting without external bias voltage.

A hospitalização infantil acarreta privações e restrições, proporcionando experiências adversas e sofrimento psíquico. A hospitalização influi na conjuntura familiar, podendo agravar os efeitos dos eventos estressores. Este estudo analisou relações entre as variáveis risco psicossocial, temperamento e estresse em 31 crianças com idade entre 5 e 7 anos (M= 5,83; DP= 0,82), internadas em hospital público de Cuiabá-MT. Foram aplicados individualmente, nos cuidadores, o Questionário de Comportamento da Criança - Children’s Behavior Questionnaire - Very Short Form e a avaliação psicossocial -Psychosocial Assessment Tool. Os resultados indicaram: a) mais famílias com risco psicossocial moderado; b) temperamento infantil facilitador, porém, mais “desconforto” para as meninas (p= 0,033; U= 65,50); c) as crianças com baixo risco psicossocial apresentaram escores menores para a subescala raiva/frustração, escores maiores para as subescalas focalização de atenção e controle inibitório; as crianças com maior risco familiar indicaram relação positiva com a subescala raiva/frustração e relação negativa com reatividade crescente/capacidade de se acalmar e controle inibitório. As dificuldades de autorregulação das crianças de famílias com maior risco psicossocial podem evidenciar o impacto de estressores, demandando atenção e cuidado dos profissionais de saúde. Tais resultados podem subsidiar intervenções dirigidas ao perfil familiar.

Published: March 2018

Today, we are experiencing what it is being labelled as the Fourth Industrial Revolution (Industry 4.0) in terms of automation and control systems of cyber - physical production environments. These systems not only allow access to many innovative features based on network connections, but they also provide access to the world of the Internet of Things (IoT). It is in this context that IoT changes the ways to link new technologies in order to obtain more efficient, intelligent, flexible and adaptable production systems; thus becoming an interdependence of the product itself that the companies wish to commercialize. Cyber- Physical Production Systems (CPPS) have the advantages of granular communications, common electric bandwidth for all users regardless of data speeds, compatibility in connection with free or guided space communication links and with the major compatibility with intensity modulation. IEC 61499 is generally based on a generic architecture, with specific software requirements, development rules that allow for portability and device configuration.Keywords: IoT, configuration, communication, CPPS, Industry 4.0, smart.

The aim of the research was to evaluate the removal of micropollutants in a combined system MBR + ozonation. The research was carried out in a MBR scale laboratory plant which was fed with synthetic wastewater, doped with simazine (SIM), atrazine (ATZ) and terbutilazine (TBZ). The MBR operational conditions were: hydraulic retention time (HRT) of 20 h, organic loading rate (OLR) of 0.23 KgCOD/KgSSV·day, sludge retention time (SRT) of 30 d, and flux of 5.5 LMH. Two ozone doses were tested: low dose (16 mg O3/L) and high dose (45 mg O3/L). The removal eficiency of organic matter was 96%. For the studied triazines, low biodegradation effiencies were reached by biological treatment (MBR): 57%, 53% and 63% for SIM, ATZ and TBZ, respectively. The complementary treatment of ozonation improved the quality of the effluents. At low ozonation dose the overall removal efficiencies increased to 95%, 92% and 96% for SIM, ATZ and TBZ, respectively. At high ozonization dose the overall removal efficiencies were 98%, 97% and 97 % for SIM, ATZ and TBZ, respectively, percentages slightly higher than those obtained at low dose. The results showed the combination of MBR + O3 is effective to remove micropollutants from wastewater, contributing to the preservation of a good ecological state of water bodies.Keywords: Bioreactor, Membrane, Ozone, Triazines, Herbicides.

Los océanos son la clave para la conservación de la vida y son la conexión para los ecosistemas y el mercado mundial. Los seres humanos somos atraídos a las zonas costeras por los múltiples beneficios que nos brinda, siendo el principal la pesca. A través de los productos del mar que consumimos, podemos resultar contaminados con toxinas que producen unos microorganismos acuáticos llamados dinoflagelados que a su vez pueden causar la enfermedad ciguatera. En Panamá dentro el Paisaje Protegido de Punta Galeta se está realizando una investigación desde junio 2016 hasta la fecha y se han encontrado tres géneros de dinoflagelados que pueden causar esta enfermedad (Gambierdiscus, Prorocentrum y Ostreopsis), siendo el primero el más abundante. Los datos obtenidos de pH en campo van en un rango de 8.02 hasta 8.63 siendo estos de poca variación, mientras que en los análisis de laboratorio para estos mismos cinco puntos se han obtenido datos en un rango de 7.89 a 8.33. Ambos resultados indican que las condiciones de pH para Punta Galeta son buenas ya que estudios previos determinan que el agua de mar presenta, de forma estable, pH comprendido entre 7-9 unidades, siendo 8 unidades el valor normal en superficie.Palabras claves: Ciguatera, dinoflagelados, mariscos, pH, algas.

Authors: Meneses Gustavo 
Published: March 2018

Structural health monitoring systems rely on electronic instrumentation and telemetry for improving maintenance tasks, preventing catastrophic failures and following the behavior of critical variables for infrastructure works such as tunnels, highways, bridges and buildings. A proposal for the development of sensor networks for monitoring Metro-de-Medellín system infrastructure is presented. The adopted approach is based on the deployment of generic sensing units that can operate either individually or by constituting wireless personal area networks un-der the MiWi P2P protocol from Microchip. Different transceivers can be added to monitoring units that can act as gateways in order to allow collected data reach other networks, ranging from local area to metropolitan area coverage. Several sensors, digital and analog, can be attached to the generic units depending on the particular requirements of specific situations and monitoring locations. The results obtained from performed tests and the options considered for graphical user interfaces are also presented.Keywords: MiWi Protocol, Structural Health Monitoring, Short Data Service, Terrestrial Trunked Radio, Wireless Sensor Networks.

Published: March 2018

Background: The objective of this study was to test a breastfeeding history questionnaire to predict inhospital formula supplementation.Methods: A breastfeeding questionnaire named BAP, an abbreviation based on three questions, was conceptualized and implemented in clinical practice. Primary outcome was formula supplementation during the postpartum hospital stay.Results: Multiparous women with BAP scores of 1 or less were over four times more likely to use formula during the postpartum hospital stay than women with BAP scores of 2 or greater (RR = 4.35, 95% CI [2.47, 7.65]; p < .001). Additionally, multiparous mothers with BAP scores of 1 or less were more likely to use formula than primiparous mothers (RR = 1.93, 95% CI [1.47, 2.52]; p < .001). The adjusted odds of formula use were eight times greater for women with the lower BAP score (aOR 8.04, 95% CI [3.10, 20.86]; p < .001).Conclusions: The BAP tool can be used to identify multiparous women most at risk for early formula use, thereby allowing targeted referral to breastfeeding support services.

Published: March 2018

Merging two Methods between lecturing and Group Investigation ar Al-Qur'an is essentially dedicated to mankind wherever they are. One method to bring the Qur'an closer to human is through the stories that are presented in Al-Quran. This paper would like to investigate more about how the description of the Ibrahim story and its relevance to the values of Islamic education. The results found the data of the verses relating to the story of the prophet Ibrahim AS, as many as 186 verses spread in 25 surah. From 25 surah there are 17 (seventeen) surah down in Mecca, and 8 (eight) surah down in Medina. Furthermore, the values of Islamic education contained in the story of Prophet Ibrahim AS consists of the first; the value of uluhiyah, namely the values of faith and the values of worship; the value of uluhiyah is the value that God offers through his rasul who are immortal and never changed; it is fundamental and contains absoluteness for human life. Secondly, the values of humanity, namely the values that come from human beings, that is grown by human agreement, lived and thrived in human civilization. It is dynamic and contains truth that is relative and limited by space and time. In the Islamic context, human values can be identified with moral values. These values are honesty (shiddiq), trustworthiness (amanah), truth-telling (tabligh), intelligence (fathanah), love, patience, exemplary, and democracy.

The high potential number of Muzakki in Sumenep needs a well organized management. Additional condition to be done for this empowerment is that the Muzakki, both individually and company, trust their zakat management on the Amil Zakat. The research focuses are: how was the real condition of the potential Muzakki in Sumenep? How is the process of zakat collection, management and distribution in BAZNAS Sumenep? What are the problems faced by BAZNAS Sumenep in order to gain professionalism in managing Zakat? And also how to improve the zakat manager’s skill? The approach used in this study is action research, participatory action research. The object of the study is BAZNAS Sumenep and BAZNAS Karanganyar Solo as the reference which is already successful in terms of professional management. The data collection used are documentation, interview, observation, and Focus group discussion (FGD). The technique of data analysis through 5 steps activity planning, first, making potential local mapping by doing observation to BAZNAS Karanganyar Solo and FGD. Second, conducting Zakat seminar. The third, improving the BAZNAS zakat organizer’s skill. Fourth, Social network development. Fifth, assistance, monitoring and evaluating process. The result shows that first, actually it is already potential in sumenep in the process of collecting Zakat, the people of sumenep is religious people who understand their responsibility to pay Zakat. Second, there is no serious attention on the management of Zakat, also on the supporting means. Third, the difficulties faced by BAZNAS Sumenep are the means and infrastructure of the office, the lack of working accountability, the Muzakki did not receive the report of Zakat management, the lack of socialization, support and guidance from local government. Fourth, organizing innovation program of BAZNAS Sumenep by doing some cooperations with SKPD, stakeholders, the board of Amil Zakat, universities and Islamic Boarding House.
