Abstract

Objective:
The purpose of this study was to determine the frequency of non-immune hydrops fetalis (NIHF) among all pregnancies referred for prenatal care at Sultan Qaboos University Hospital (SQUH) during the study period and to evaluate the underlying etiologies of NIH.

Study design:
All pregnancies referred to SQUH between February 2014 and December 2015 were identified, and all pregnancies meeting the diagnosis of NIHF were included in this study. All cases of NIHF referred to our center during this period underwent standard systematic diagnostic work-up that included biochemical and molecular studies in addition to the standard investigations for hydrops fetalis. Clinical characteristics and results of the diagnostic work-up were retrospectively reviewed.

Results:
A total of 3234 pregnancies were referred for prenatal care at SQUH during the study period, and 12 pregnancies were affected by NIHF. An underlying diagnosis was established in nine cases, and the majority of cases (7/9) were caused by inborn errors of metabolism (IEM). These included a novel homozygous variant in the AARS2 gene (5/7) and two cases of galactosialidosis (2/7).

Conclusion:
IEM was a major cause of NIHF in this cohort. The AARS2 variant accounts for a significant number of cases with NIHF in this cohort of Omani patients.
Trade Potential of China’s Export to ASEAN: The Gravity Model Using New Economic Mass Proxies
Authors: Zhang Yuqin , Wang Shouyang 
Published: August 2017

AbstractConsidering the fact that China is the world factory, in which the trade of intermediate goods has a relatively high share and especially that the trade of intermediate goods with ASEAN is even higher, it is not suitable to use GDP as the economic mass proxies in the gravity model to estimate trade flows traditionally. This paper, by using the data between China and 10 member states of ASEAN along with other 12 main trading partners of China from 1999 to 2013, constructs China’s bilateral export equation based on the gravity model using new economic mass proxies according to Baldwin and Taglioni, and then calculates the trade potential index of China’s export to the member states of ASEAN by using this equation. The empirical results show that, China’s export trade equation based on new economic mass proxy has stronger explanatory power compared to the standard gravity model by using GDP as economic mass proxy. Therefore, the calculating results of trade potential of China’s export to ASEAN are more convincing.

Published: August 2017

AbstractBased on association rules, this article proposed a method for intelligent recommendation of power supply mode, which helps decision-makers in the selection of many schemes. Firstly, a history database which includes the forecasting models and correlative factors was first built and association rule mining was conducted; then combined with the correlative factors in the designated area, the criteria matching in the rules mined were carried out with CBR technique; finally automatic recommendation of the power supply modes was achieved under the given conditions. By application of an example, it is demonstrated that the proposed method can not only automatically analyze the applicability of power supply modes and the intrinsic relationship between correlative factors but also provide, to some extent, theoretical basis for selection of power supply modes and practical utility for urban distribution network planning.

Published: August 2017

BACKGROUND AND OBJECTIVES:
The American Academy of Pediatrics recommends infants be placed supine for sleep. Our objectives in this study were to, in a nationally representative sample, examine (1) prevalence of maternal intention regarding infant sleeping position and of actual practice and (2) factors associated with their choices.

METHODS:
We recruited mothers from 32 US hospitals, oversampling African American and Hispanic mothers, in a nationally representative sample of mothers of infants aged 2 to 6 months. Survey questions assessed choice of usual infant sleeping position, all sleeping positions, intention for sleep position, as well as actual practice. Multivariable logistic regression analyses controlled for demographic, receipt of doctor advice, and theory of planned behavior variables (attitudes, subjective norms, and perceived control).

RESULTS:
Of the 3297 mothers, 77.3% reported they usually placed their infants in the supine position for sleep, but fewer than half reported that they exclusively did so. Only 43.7% of mothers reported that they both intended to and then actually placed their infants exclusively supine. African American mothers and those who did not complete high school were more likely to intend to use the prone position. Theory of planned behavior factors (attitudes, subjective norms, and perceived control) and doctor advice were associated with maternal choice.

CONCLUSIONS:
Not all mothers place their infants exclusively supine for sleep. Many mothers intend to place their infants supine yet often do not do so in actual practice. Factors potentially amenable to intervention including attitudes, subjective norms, and doctor advice are associated with intention and practice.

This Clinical Report was reaffirmed July 2021.
Children and adolescents may participate in sports that favor a particular body type. Some sports, such as gymnastics, dance, and distance running, emphasize a slim or lean physique for aesthetic or performance reasons. Participants in weight-class sports, such as wrestling and martial arts, may attempt weight loss so they can compete at a lower weight class. Other sports, such as football and bodybuilding, highlight a muscular physique; young athletes engaged in these sports may desire to gain weight and muscle mass. This clinical report describes unhealthy methods of weight loss and gain as well as policies and approaches used to curb these practices. The report also reviews healthy strategies for weight loss and weight gain and provides recommendations for pediatricians on how to promote healthy weight control in young athletes.

Published: August 2017

Abstract: Introduction: Structure, importance and incidence and clinical role of macro-TSH not clarified in thyroid diseases. Aim: This study was undertaken to determine the incidence and biological role of macro-TSH in patients with Hashimoto’s thyroiditis. Method: Blood samples taken from patients with Hashimoto’s thyroiditis were screened for the presence of macro-TSH with the polyethylene glycol method and confirmed with protein G agarose absorption test and gel filtration chromatography. Stimulatory capacity of macro-TSH was measured by CHO cells bio-assay. Patients were treated with L-thyroxine (mean 66.5 µg/day) and half of them with selenium (mean 60 µg/day), respectively. Results: 880 patients (728 female, aged 44.8 yr) with Hashimoto’s thyroiditis was involved in the study. Macro-TSH was found in the serum of 41 patients (4.6%), the mean TSH 185.4 ± 35 IU/l was before PEG precipitations and after 5.55 ± 1.8 IU/l. Titre of anti-TPO proved to be 445 ± 51 IU/l and gradulally decreased to 212 ± 51 IU/l after one year therapy. Both the precipitation, protein G absorption and gel chromatography supported the presence of anti-TSH antibody in the macro-TSH complex. Stimulatory capacity of macro-TSH on CHO bio-assay was not proved. The macro-TSH was detected in the selenium not treated group for 18 ± 3.2 months, selenium-treated for 12 ± 1.9 months. Conclusion: It is concluded that anti-human TSH autoantibodies are a major components of macro-TSH and may cause diagnostic and therapeutical difficulties. The PEG precipitation is a suitable screening method for detection of macro-TSH. Selenium is able to decrease of anti-TPO antibodies and macro-TSH, respectively. When the TSH level is greater than 40.0 IU/l, without the signs of hypothyroidism, the presence of macro-TSH is to be considered. Orv Hetil. 2017; 158(34): 1346–1350.

An Experimental Study of Acid Matrix Treatment Performance On Shale Core Samples
Authors: Khalil Rayan E. , Mansour Ahmed , Gamadi Talal 
Published: August 2017

Abstract
Experimental and numerical studies have demonstrated that there is great potential of enhancing the oil recovery from tight formations. This study investigated the effect of acid matrix treatment by applying gas flooding on the core samples before and after the treatment. The aim of the acid stimulation treatment was to improve the low-permeability of the cores.
Four core samples (0.5 in, 1.0 in, 1.5 in, and 2.0 in) from an outcrop of the Eagle Ford formation were used in this study. Permeability was measured before and after the acid treatment. The cores were CT-scanned to identify natural fractures. Different gas injection pressures were used to study the oil recovery and the time needed to penetrate through core samples. Furthermore, a solubility test was applied to identify the optimal acid concentration. The cores were re-scanned after the acid flooding treatments to detect any change. Gas flooding was applied to acidized core samples to detect changes in penetration time and recovery factor.
A solubility test demonstrated that 15% of HCL was the optimal acid concentration for the Eagle Ford formation. The study showed the porosity, permeability, recovery factor, and penetration time before and after the acidizing treatment. Permeability was enhanced from 1.04 nanodarcies to 2.10 microdarcies. Furthermore, the study showed the effect of core length on penetration rate (in/min) of gas flooding and the recovery factor at each injecting pressure. The penetration time in this study varied from 207 to 112 minutes/inch when the injecting pressure increased from 1500 to 2500 psi. After acidizing, however, the penetration rate decreased to 8.4 minutes/inch using flooding of 300 psi. The CT scan showed improvement of the micro fracture width.
Depressurizing Permian Basin San AndresResidual Oil Zones: A Feasibility Study
Authors: Jamali Ali , Ettehadtavakkol Amin , Watson Marshall , Zeinuddin Omar 
Published: August 2017

AbstractA Residual Oil Zone (ROZ) is a naturally waterflooded reservoir at residual or near residual oil saturation, technically recoverable only through unconventional methods. The development of ROZs is extensively pursued in the Texas Permian Basin. Several successful ROZ CO2 Enhanced Oil Recovery (CO2-EOR) projects indicate enormous resource potential for these emerging oil plays. Another approach, called Depressurizing the Upper ROZ (DUROZ), was recently proposed and is currently under extensive investigation. This study offers a mechanistic understanding of DUROZ and investigates the factors affecting its viability and performance.DUROZ refers to the progressive reduction of reservoir pressure through the withdrawal of large volumes of water from a horizontal well in the upper section of ROZ. When reservoir pressure falls below the saturation pressure, gas bubbles liberate from capillary-trapped oil and develop into a continuous gas phase. Consequently, the oil phase may also become mobile beyond waterflood residual oil saturation. We history-match the oil and water production from twoDUROZ producers in the upper San Andres dolomite using a tuned reservoir simulation model. To properly capture the rock and fluid interaction, the relative permeability data are tuned with the experimental core datafrom the San Andres ROZ. Extensive experimental studies have highlighted a substantial difference between relative permeabilities measured under external drive and solution gas drive. We define two sets of relative permeabilities: an original set based on the external drive experiments and the relevant correlations, and a modified set for modeling production under solution gas drive.Our results show that even for the most optimistic relative permeabilities, the reservoir initial oil saturation should be at least 20% above the residual oil saturationin order to match the oil cuts of the reported DUROZ producers. This shows inconsistencies in use of the term "residual oil"zone by the industry in the Permian Basin. In other words, although DUROZ shows potential for production beyond waterflood residual oil saturation, the documented cases are unlikely to be true ROZ producers and are more likely completed in the Transition Zone (TZ) or near-ROZ. Finally, a discussion on the operational risks and technical considerations associated with DUROZ, including water disposal, infrastructure and facility requirements, and modeling limitations, is presented.
