Evaluation of the effects of adenotonsillar hypertrophy and adenotonsillectomy on growth in children

Sum mary Aim: Several factors including genetic factors, nutrition and environment play a critical role in the growth of children. Adenotonsillar hypertrophy (ATH) can cause growth retardation by obstructing the upper airway. Surgical treatment of ATH has been considered to have a positive effect on growth. The aim of this study was to evaluate the role of chronic ATH on growth by measuring weight, height, body mass index (BMI), bone age, serum insulin-like growth factor 1 (IGF-1) and insulin-like growth factor binding protein 3 (IGFBP-3) values before and after adenotonsillectomy. Material and Method: The study was approved by the Ethics Committee (4.5.2004; 04/170) and written informed consents were obtained from parents of the participants. A total of 40 prepubertal children who were diagnosed as chronic ATH were enrolled. Obstructive symptoms were questioned in the medical history before surgery. Weight, height, BMI and bone age values were measured and compared with reference values. Preoperative serum IGF-1 and IGFBP-3 values were compared with the control group which consisted of healthy children. Rates of obstructive symptoms, weight, height, BMI, bone age, serum IGF-1 and IGFBP-3 values of the patients were determined seven months after adenotonsillectomy and were compared with preoperative values. Results: Obstructive symptoms in children with ATH decreased remarkably after surgery. Preoperative mean value of bone age of the patients was statistically lower than reference values (p<0.05) and mean value of serum IGF-1 was lower than than the control group (p<0.05). IGF-1 and IGFBP3 values did not increase significantly after surgery (p>0.05). However, growth retardation was detected in three out of 40 patients based on the anthropometric measurements. Conclusions: In this study, antropometric findings showed that chronic ATH did not cause significant growth retardation in prepubertal children. In addition, we could not prove that surgical treatment of ATH improved the growth in the postoperative follow-up period of seven months. This result may be related with our study population with a limited number of patients who had baseline growth retardation and short postoperative follow up period. Further studies with large number of patients and longer postoperative follow-up periods are required to determine the exact role of chronic ATH in growth retardation.

Effect of Perceived Ease of Use, Word-of-Mouth Communication, and Brand Image on Decision to Use Lazada E-Commerce Services

The rapidly growing communication, media and information technology and the widespread development of global information infrastructure has influenced the ways and patterns of business activities in the trade industry, social and political governance. Indonesia is one of the countries that has the largest internet growth after China and India. This growth is likely to form online buying and selling transactions. It is supported by a survey conducted by APJII (Association of Indonesian Internet Service Providers) about Internet Users in Indonesia in 2016 that the most frequently visited commercial content was online shop (62%) or equal to 82.2 million. Visitors and big opportunities for online shops have an impact on the emergence of more e-commerces whose goods or products sold come from the website or application itself without giving opportunity or place for other sellers to sell their products. Based on the data from CNN Indonesia, the number of Lazada app’s downloaders is in first place followed by its competitors Tokopedia and Bukalapak. The abundance of e-commerce in Indonesia creates increasingly fierce competition. Many e-commerce applications or websites provide display menu that makes it easier for users to shop, quality and complete items, varied price ranges, and trusted image of the e-commerce.
Gross and histological types of early gastric carcinomas in relation to the acid‐secreting area

The relation of gastric acid‐secreting function to the gross and histological types and locations of carcinomas was examined in 53 patients with early gastric carcinomas. Studies were made by the endoscopic Congo red test developed in this clinic. Results indicated a close correlation between the gross and histological types of early gastric carcinoma and the extent of the acid‐secreting area. In general, when the acid‐secreting area was large, the carcinomas were ulcerated and histologically undifferentiated, and they were chiefly located in nonacid‐secreting areas adjacent to acid‐secreting areas, or sometimes they were surrounded by acid‐secreting areas. On the contrary, when there was little or no acid‐secreting area the carcinomas were polypoid and histologically differentiated, and they were located in nonacid‐secreting areas far from acid‐secreting areas.
DESIGN OF RESILIENT GENERAL CRITERIA CONTROLLERS FOR NONLINEAR SYSTEMS WITH UNCERTAINTIES

A resilient and robust state feedback control scheme is proposed to control a large class of uncertain nonlinear systems with locally conic type of nonlinearities and driven by finite energy disturbances. Resilience property is achieved by satisfying various performance requirements in the presence of bounded perturbations in the feedback gain. System models are also allowed to contain a high degree of uncertainty involving perturbations in the center and the radius of the cone in which the nonlinearity resides that result in a robust design. Linear matrix inequality (LMI) techniques are used in the mathematical formulation. Various commonly used performance criteria are treated in a unified framework. Illustrative examples are included to demonstrate the effectiveness of the proposed methodology and to compare the relative performance of the controllers.

Near-infrared coloring via a contrast-preserving mapping model

Near-infrared gray images captured together with visible color images have recently proven useful for image enhancement and restoration. This paper introduces a new coloring method for adding colors to near-infrared gray images via a contrast-preserving mapping model. A naive coloring method directly adds the colors from the visible color image to the near-infrared gray image; however, this method results in an unrealistic image because of the discrepancies in brightness and image structure between the near-infrared gray image and the luminance plane of the visible color image. To solve this problem, a local linear mapping model with a local contrast constraint is proposed to find the relation between the near-infrared gray image and the luminance plane of the visible color image. This contrast-preserving linear mapping model enables the creation of a new near-infrared gray image that has a similar appearance to the luminance plane of the visible color image, but preserves local contrasts of the near-infrared gray image. In addition, the proposed mapping model can be utilized to transfer the colors from the visible color image to the newly created near-infrared gray image. The experimental results show that the proposed method not only preserves the local contrast and details of the near-infrared gray image, but also transfers the realistic colors from the visible color image to the near-infrared gray image.
User preferences dynamics on evolving social networks - learning, modeling and prediction: student research abstract

What drives people's preferences dynamics? Modeling users' preferences and needs is one of the most important personalization tasks in information retrieval and recommender systems domains. User preferences are fairly dynamic, since users tend to exploit a wide range of items and modify their tastes accordingly over time. Moreover, all the time users are facing with others' opinions and suffering social influence. In our research, we investigate the interplay of structure and content in social interaction to exploit how user preferences evolve over time. The main objective is to develop a model for user preferences dynamics and algorithms to predict them.
Effect of naturally occurring coagulase-negative staphylococcal infections on experimental challenge with major mastitis pathogens.

The influence of pre-existing Staphylococcus sp. IMI on development of new IMI after experimental challenge with Staphylococcus aureus and Streptococcus agalactiae was studied. The IMI data were analyzed from five trials in which quarters were challenged with major pathogens incident to studies of teat dip efficacy. Prior to each trial, quarter IMI status was determined, and new IMI were enumerated during challenge. Percentage of new Staph. aureus IMI in uninfected quarters was 3-fold that of quarters already infected with Staphylococcus sp. Of quarters that were initially uninfected, 13.23% acquired new Staph. aureus IMI, and 4.49% of quarters infected with Staphylococcus sp. became infected. Conversely, the percentage of new Strep. agalactiae IMI in quarters infected with Staphylococcus sp. was 1.5-fold that of uninfected quarters (8.38 vs. 5.52%). The percentage of clinical Staph. aureus IMI in uninfected quarters was higher than for quarters infected with Staphylococcus sp. , but percentages of clinical Strep. agalactiae IMI were similar among IMI statuses. Geometric mean SCC prior to challenge were 87 x 10(3) for uninfected quarters and 260 x 10(3)/ml for quarters infected with Staphylococcus sp. Quarters infected with Staphylococcus sp. were less susceptible to Staph. aureus IMI, but more susceptible to Strep. agalactiae IMI.
Fibronectin and laminin enhance gingival cell attachment to dental implant surfaces in vitro.

The objective of this study was to determine if the biologically active molecules laminin and fibronectin could influence gingival cell attachment to implant surfaces in vitro. Flat squares of the following implant materials were tested: smooth, plasma-sprayed, and hydroxyapatite-coated titanium. The surfaces were coated with equimolar quantities of either laminin, fibronectin, or bovine serum albumin. Fibronectin coating of implant surfaces resulted in two to three times the enhancement of gingival fibroblast binding on all implant surfaces tested (P < .01), with a lesser effect on epithelial cells. Laminin coating resulted in three to four times the enhancement of gingival epithelial cell binding on all implant surfaces tested (P < .01), with a lesser effect on fibroblasts. The two cell types exhibited distinct preferences for the different molecules tested with the surface roughness having some influence.
Calculation of the armature inductance of the universal AC commutator motor

This paper presents an analytical method for calculating the direct- and quadrature-axis inductances of the universal AC commutator motor, suitable for use in design calculations. These inductances are important in understanding the steady-state and transient behaviour, and the commutation. The analysis concentrates on the parameters affecting these inductances, and draws attention to the rarely-mentioned reluctance torque of this machine.
Making an exception: market design and the politics of re-regulation in the French electricity sector

Abstract By subjecting market participants to uncertain and volatile prices, the liberalization of public concerns generates opposition that threatens its own survival. This paper asks how this contradiction is resolved in practice. We examine the case of the French electric power industry. When this sector was liberalized and integrated with European markets, a period of unexpectedly high prices brought strenuous objections from the French electro-intensive industries, and a crisis in political support for liberalization. Based on interviews with key participants and analysis of the documentary record, we trace a series of efforts to reach a political accommodation. Liberalization has not realized the neoliberal imaginary of an efficient and peaceful allocation of state services. But it has effectively transformed the terms under which political-economic struggles proceed, mediating, constraining and governing the politics of distribution.
Immunohistochemical and ultrastructural studies of basal cells, Clara cells and bronchiolar cuboidal cells in normal human airways

Immunohlstochemical studies were made of the distribution of various cytokeratins (CK), Clara cell secretory protein (CC10), surfactant proteln A (SP‐A) and type VII collagen in normal human alrways. Electron microscopic studies were made to Identify hemldesmosomes and anchoring fibrils on the basal surfaces of the epithelial cells. CK19 was detected In all epithelial cells, and CK17 in all basal cells. CK14 was coaxpressed in a few basal cells, and this coexpression was decreased in the distal airways. Two types of basal cells were recognized. One type, found mainly In large airways, was characterized by abundant intermediate filaments and well‐developed hemidesmosomes and anchoring fibrils. The second type contained few intermediate filaments and poorly developed hemidesmosomes and anchoring fibrils. Reactivity for type VII collagen was found along the basement membrane throughout the airways, but not in the alveoli. Clara cells were reactive for CC10 and CK17, but not for CK14 and SP‐A. The bronchiolar cuboidal cells in the respiratory bronchloles were positive only for CK19. Surfactant proteln A was present only in type II alveolar eplthellal cells. Thus, two types of basal cells are present in always, and the bronchiolar cuboidal cells appear distinct from these basal cells, Clara cells and type II alveolar epithelial cells.
Inertial frequency response provided by battery energy storage systems: Probabilistic assessment

This paper proposes a methodology for assessment to measure the impact of the inertial frequency response provided by battery energy storage systems (BESS) considering power system uncertainties. The proposed methodology is used to assess the impact of the BESS equipped with sensible frequency controller on the frequency behaviour of the system after a system frequency disturbance considering the variability coming from power system uncertainties. The proposed meteorology is tested in an illustrative power system considering the integration of a grid-scale BESS equipped with inertial frequency response controller, the uncertainty of the power system is simulated by the variability of the power demand. Monte Carlo simulations and time-domain simulations, using DIgSILENT® PowerFactory™ are combined in the implementation of the proposed methodology. Simulation results demonstrate the suitability of the proposed approach to obtain probabilistic distribution functions (PDF) of the main system frequency response.
Radioactive iodine treatment and external radiotherapy for lung and bone metastases from thyroid carcinoma.

UNLABELLED We assessed the therapeutic benefits of 131I treatment in patients with distant metastases of differentiated thyroid carcinoma. METHODS Of 2200 patients treated for differentiated thyroid carcinoma at our institution, 394 had lung and/or bone metastases. RESULTS Two-thirds of the patients had 131I uptake in their metastases, but only 46% achieved a complete response. Prognostic factors for complete response were: younger age, presence of 131I uptake in the metastases and small extent of disease. The survival rate was 33% at 15 yr. As shown by multivariate analysis, favorable prognostic factors for survival were: younger age and time of metastases detection, well-differentiated histologic type of the thyroid tumor, presence of 131I type uptake in the metastases, small extent of the disease and year of discovery of metastases. CONCLUSION In terms of survival, the benefits of 131I therapy cannot be demonstrated by prospective controlled studies. The present study clearly demonstrates, however, that treatment with 131I is one of the factors which accounts for survival; patients whose metastases concentrated 131I and who could be treated with radioiodine had higher survival rates. Patients who achieved complete response following treatment of distant metastases had a 15-yr survival rate of 89%, while those who did not achieve complete response had a survival rate of only 8%. The survival rate improved with the year of discovery of distant metastases, after 131I total-body imaging and serum thyroglobulin measurements were routinely used.
Do Structural Inequalities Contribute to Marital Violence? Ethnographic Evidence From Rural South India

Ethnographic research was conducted in rural communities in Karnataka State, South India, to explore the contexts in which marital violence occurs and the relationships between structural inequalities (gender, caste, and class inequalities) and marital violence. Research highlighted that (a) marital violence is intimately linked to experiences of gender, caste, and class inequalities; (b) women’s ability to resist violence hinges on access to economic and social resources; and (c) health care providers need to be actively involved in responding to violence. This study demonstrates the urgent need for violence prevention initiatives, particularly those that address the contribution of structural inequalities.
Accuracy and precision of the CKD-EPI and MDRD predictive equations compared with glomerular filtration rate measured by inulin clearance in a Saudi population

BACKGROUND Predictive equations for estimating glomerular filtration rate (GFR) in different clinical conditions should be validated by comparing with the measurement of GFR using inulin clearance, a highly accurate measure of GFR. OBJECTIVES Our aim was to validate the Chronic Kidney Disease-Epidemiology Collaboration (CKD-EPI) and Modification of Diet in Renal Disease (MDRD) equations by comparing it to the GFR measured using inulin clearance in chronic kidney disease (CKD) patients. DESIGN Cross-sectional study performed in adult Saudi patients with CKD. SETTING King Saud University Affiliated Hospital, Riyadh, Saudi Arabia in 2014. PATIENTS AND METHODS We compared GFR measured by inulin clearance with the estimated GFR calculated using CKD-EPI and MDRD predictive formulas. MAIN OUTCOME MEASURE(S) Correlation, bias, precision and accuracy between the estimated GFR and inulin clearance. RESULTS Comparisons were made in 31 participants (23 CKD and 8 transplanted), including 19 males (mean age 42.2 [15] years and weight 68.7 [18] kg). GFR using inulin was 51.54 (33.8) mL/min/1.73 m2. In comparison to inulin clearance, the GFR by the predictive equations was: CKD-EPI creatinine 52.6 (34.4) mL/min/1.73 m2 (P=.490), CKD-EPI cystatin C 41.39 (30.30) mL/min/1.73 m2 (P=.002), CKD creatinine-cystatin C 45.03 (30.9) mL/min/1.73 m2 (P=.004) and MDRD GFR 48.35 (31.5) mL/min/1.73 m2 (P=.028) (statistical comparisons vs inulin). Bland-Altman plots demonstrated that GFR estimated by the CKD-EPI creatinine was the most accurate compared with inulin clearance, having a mean difference (estimated bias) and limits of agreement of −1.1 (15.6, −17.7). By comparison the mean differences for predictive equations were: CKD-EPI cystatin C 10.2 (43.7, −23.4), CKD creatinine-cystatin C 6.5 (29.3, −16.3) and MDRD 3.2 (18.3, −11.9). Except for CKD-EPI creatinine, all of the equations underestimated GFR in comparison with inulin clearance. CONCLUSIONS When compared with inulin clearance, the CKD-EPI creatinine equation is the most accurate, precise and least biased equation for estimation of GFR in the Saudi population and in all subgroups by age, stage of CKD and transplantation status. LIMITATIONS Small sample size and the study did not include patients with comorbid diseases such as diabetes, hepatitis C virus infection, and other co-morbidities as well as old age (>80 years).
