AbstractEnlargement of the left atrium is perceived as a part of athlete’s heart syndrome, despite the lack of evidence. So far, left atrial size has not been assessed in the context of exercise capacity. The hypothesis of the present study was that LA enlargement in athletes was physiological and fitness-related condition. In addition, we tried to assess the feasibility and normal values of left atrial strain parameters and their relationship with other signs of athlete’s heart. The study group consisted of 114 international-level rowers (17.5 ± 1.5 years old; 46.5% women). All participants underwent a cardio-pulmonary exercise test and resting transthoracic echocardiography. Beside standard echocardiographic measurements, two dimensional speckle tracking echocardiography was used to assess average peak atrial longitudinal strain, peak atrial contraction strain and early left atrial diastolic longitudinal strain. Mild, moderate and severe left atrial enlargement was present in 27.2°%, 11.4% and 4.4% athletes, respectively. There were no significant differences between subgroups with different range of left atrial enlargement in any of echocardiographic parameters of the left ventricle diastolic function, filling pressure or hypertrophy. A significant correlation was found between the left atrial volume index and maximal aerobic capacity (R > 0.3; p < 0.001). Left atrial strain parameters were independent of atrial size, left ventricle hypertrophy and left ventricle filling pressure. Decreased peak atrial longitudinal strain was observed in 4 individuals (3.5%). We concluded that LA enlargement was common in healthy, young athletes participating in endurance sport disciplines with a high level of static exertion and was strictly correlated with exercise capacity, therefore, could be perceived as another sign of athlete’s heart.

Abstract
There were two aims of this study: first, to investigate physical fitness and match performance differences between under-16 (U16) and under-18 (U18) female basketball players, and second, to evaluate the relationship between physical fitness and game-related performances. Twenty-three young, female, elite Spanish basketball players (16.2 1.2 years) participated in the study. The sample was divided into two groups: U16 and U18 players. The average scores from pre- and post-season physical fitness measurements were used for subsequent analyses. Anthropometric variables were also measured. To evaluate game performance, game-related statistics, including the number of games and minutes played, points, rebounds, assists, steals and blocks per game, were recorded for every competitive match in one season. When anthropometric and physical performance variables were compared between groups, the U18 group demonstrated significantly (p<0.05) higher values in upper (+21.2%) and lower (+27.11%) limb strength compared to the U16 group. Furthermore, no significant differences between groups were observed in match performance outcomes. Only two performance variables, steals and assists per game, correlated significantly with jump capacity, speed, agility, anaerobic power, repeated sprint ability and aerobic power (p ≤ 0.005). These findings can help optimize training programs for young, elite female basketball players.

Abstract
This study analysed the physiological, nutritional and performance profiles of athletes practicing Brazilian jiu-jitsu. To this end, 15 athletes that practiced Brazilian jiu-jitsu (aged: 28 ± 5 years; 8 brown belts and 7 black belts; training experience: 11 ± 4 years) underwent anthropometric measurements (body composition and somatotype), dietary evaluation (24 h recall) and physical fitness tests (movement time, dynamometer handgrip, kimono grip strength, vertical jump and sit-and-reach tests). The athletes had 12.7 ± 4.8% of body fat, 59.2 ± 5.0% of muscle mass and their somatotype was dominated by the mesomorphic component (5.3 ± 2.0), followed by endomorphic (3.7 ± 1.5) and ectomorphic (1.4 ± 0.9) components. Nutritional assessment suggested a diet consisting of 54 ± 7% of carbohydrates, 19 ± 4% of protein and 27 ± 6% of lipids. Movement time on the handgrip tests was 0.42 ± 0.05 s, for handgrip strength, 53 ± 7 kgf was found for the dominant hand and 50 ± 9 kgf for the non-dominant hand. For the countermovement jump, the jiu-jitsu athletes reached 41 ± 5 cm. Athletes remained 30 ± 14 s in the maximum static suspension test gripping a kimono, and reached 27 ± 8 cm in the sit-and-reach test. Overall the sample presented average levels of body fat, elevated muscle mass and a predominantly mesomorphic somatotype. Diet was generally poor, with low carbohydrate intake, high protein intake and adequate lipid intake. Maximum isometric handgrip strength was consistent with observations of other athletes in this sport discipline. However, the performance in the maximum static suspension test gripping a kimono was lower than in other Brazilian jiu-jitsu athletes. Movement time was comparable and lower body muscle power was worse compared to athletes in similar sports. Additionally, flexibility was rated as poor.
Selection of an Estimation Window in the Presence of Data Revisions and Recent Structural Breaks
Authors: Hännikäinen Jari 
Published: October 2016

AbstractIn this paper, we analyze the forecasting performance of a set of widely used window selection methods in the presence of data revisions and recent structural breaks. Our Monte Carlo and empirical results for U.S. real GDP and inflation show that the expanding window estimator often yields the most accurate forecasts after a recent break. It performs well regardless of whether the revisions are news or noise, or whether we forecast first-release or final values. We find that the differences in the forecasting accuracy are large in practice, especially when we forecast inflation after the break of the early 1980s.
Multi-Objective Optimization of Bead Geometry for Submerged Arc Welding of Pipeline Steel Using RSM-Fuzzy Approach
Authors: Sharma Satish Kumar , Maheshwari Sachin , Rathee Sandeep 
Published: October 2016

AbstractIn this paper, for the purpose of better control as well as multi-objective optimization of bead geometry parameters, the optimal combination of submerged arc welding (SAW) process variables is determined using fuzzy logic approach. Open circuit voltage, trolley speed, contact tube to work distance, preheating temperature and wire feed rate are taken as process variables during SAW of the pipeline steel. For this experimental investigation, experiments are designed and performed according to response surface methodology (RSM). Bead width, penetration, and reinforcement are taken as the performance measures in bead geometry. In fuzzy logic, two membership function (MF) namely triangular and trapezoidal are employed for the performance comparison of SAW process. As compared to triangular MF, the use of trapezoidal MF has given the more logical and better-optimized results for bead geometry parameters. Outcomes of the study are also confirmed by conducting the confirmatory experiments.
Decomposition of a second-order linear time-varying differential system as the series connection of two first order commutative pairs
Authors: Koksal Mehmet Emir 
Published: October 2016

Abstract
Necessary and sufficiently conditions are derived for the decomposition of a second order linear time- varying system into two cascade connected commutative first order linear time-varying subsystems. The explicit formulas describing these subsystems are presented. It is shown that a very small class of systems satisfies the stated conditions. The results are well verified by simulations. It is also shown that its cascade synthesis is less sensitive to numerical errors than the direct simulation of the system itself.
Simple method for manufacturing and optical characterization of tapered optical fibres
Authors: Zakrzewski A. , Pięta A. , Patela S. 
Published: October 2016

AbstractPhotonic devices often use light delivered by a single-mode telecommunication fibre. However, as the diameter of the core of the optical fibre is of 10 microns, and the transverse dimensions of the photonic waveguides are usually micrometer or less, there is an issue of incompatibility. The problem may be solved by application of tapered optical fibres. For efficient light coupling, the taper should be prepared so as to create a beam of long focal length and small spot diameter in the focus. The article describes the design, fabrication and characterization of tapered optical fibres prepared with a fibre-optic fusion splicer. We modelled the tapers with FDTD method, for estimation of the influence of the tapered length and angle on the spot diameter and the focal length of an outgoing beam. We fabricated tapers from a standard single mode fibre by the Ericsson 995 PMfi- bre-optic fusion splicer. We planned the splicing technology so as to get the needed features of the beam. We planned a multistep fusion process, with optimized fusion current and fusion time. The experimental measurements of best tapered optical fibres were carried out by the knife-edge method.

Published: October 2016

Abstract
A high molecular weight chitosan was chemically modified to quantitatively incorporate quaternary ammonium groups. Its efficiency was evaluated in the liquid-solid separation for various liquors, and compared with the one of a polyelectrolyte usually used for this utilization. The performance of the liquid-solid separation was estimated through the determination of two parameters measured after the screening- settling of the mixture liquor/flocculating agent: the separation efficiency (EV) and the TS removal efficiency (ETS). Apart for liquor 6, TS removal was always better after an addition of functionalized chitosan. Furthermore, whatever the type of liquor, the distribution was modified by an increased presence of high-size particles when functionalized chitosan was added. Moreover, chitosan addition tended to homogenize the size of the particles, which could facilitate the choice of the liquid-solid separation process. This homogenization was particularly observed for the liquor initially highly dispersed in size, i.e. liquors 1, 4, 6 and 8.

Abstract
We previously reported that trait aggression, proposed as an endophenotype for suicidal behavior, is positively associated with Toxoplasma gondii (T. gondii) seropositivity in females, but not in males. Additionally, older males seropositive for T. gondii had lower scores on measures of trait aggression, including self-aggression. Trait aggression may be influenced by dopaminergic signaling, which is known to be moderated by gender and age, and potentially enhanced in T. gondii positives through the intrinsic production of dopamine by the microorganism. Therefore, we investigated associations between trait aggression and interactions between T. gondii enzyme-linked immunoabsorbant assay (ELISA) IgG titer-determined seropositivity and high-performance liquid chromatography- (HPLC-) measured blood levels of dopamine precursors phenylalanine (Phe), tyrosine (Tyr), and their ratio in a sample of 1000 psychiatrically healthy participants. Aggressive traits were assessed using the questionnaire for measuring factors of aggression (FAF), the German version of the Buss-Durkee hostility questionnaire. We found that 1) the decrease in trait aggression scores in T. gondii
-positive older males was only present in individuals with a low Phe:Tyr ratio, and 2) that there was a positive correlation between Phe:Tyr ratio and total aggression and selected subscales of aggression in T. gondii-positive males, but not in T. gondii-negative males. These findings point toward a gender-specific reciprocal moderation by Phe:Tyr ratio and T. gondii seropositivity of their associations with aggression scores, and lead to experimental interventions geared to manipulating levels of dopamine precursors in selected T. gondii positive individuals with increased propensity for aggression.

Abstract
We investigate a discrete negative order potential Korteweg–de Vries (npKdV) equation via the generalised Cauchy matrix approach. Solutions more than multisoliton solutions of this equation are derived by solving the determining equation set. We also show the semidiscrete equation and continuous equation together with their exact solutions by considering the continuum limits.

Published: October 2016

OBJECTIVE:
To describe recent, 10-year trends in pediatric hospital resource use with and without a psychiatric diagnosis and examine how these trends vary by type of psychiatric and medical diagnosis cooccurrence.

METHODS:
A retrospective, longitudinal cohort analysis using hospital discharge data from 33 tertiary care US children’s hospitals of patients ages 3 to 17 years from January 1, 2005 through December 31, 2014. The trends in hospital discharges, hospital days, and total aggregate costs for each psychiatric comorbid group were assessed by using multivariate generalized estimating equations.

RESULTS:
From 2005 to 2014, the cumulative percent growth in resource use was significantly (all P &lt; .001) greater for children hospitalized with versus without a psychiatric diagnosis (hospitalizations: +137.7% vs +26.0%; hospital days: +92.9% vs 5.9%; and costs: +142.7% vs + 18.9%). During this time period, the most substantial growth was observed in children admitted with a medical condition who also had a cooccurring psychiatric diagnosis (hospitalizations: +160.5%; hospital days: +112.4%; costs: +156.2%). In 2014, these children accounted for 77.8% of all hospitalizations for children with a psychiatric diagnosis; their most common psychiatric diagnoses were developmental disorders (22.3%), attention-deficit/hyperactivity disorder (18.1%), and anxiety disorders (14.2%).

CONCLUSIONS:
The 10-year rise in pediatric hospitalizations in US children’s hospitals is 5 times greater for children with versus without a psychiatric diagnosis. Strategic planning to meet the rising demand for psychiatric care in tertiary care children’s hospitals should place high priority on the needs of children with a primary medical condition and cooccurring psychiatric disorders.

Published: October 2016

Background: The aim of this systematic review is to evaluate the relationship between two methods used to assess implant stability, investigating whether both provide similar implant stability assessments for the same clinical case.Methods: A literature search was conducted on MEDLINE‐PubMed and Scopus databases, without limitation of the publication period, up to November 2015. The following key words were used, with associations among them: “dental implant,” “dental implants,” “Osstell,” “resonance frequency analysis,” “implant stability quotient,” “ISQ,” “Periotest,” “Periotest value,” and “PTV.” Inclusion criteria were English language, prospective, retrospective, and randomized controlled clinical trials that evaluated implant stability through use of resonance frequency analysis (RFA) and damping capacity analysis (DCA). The study should assess implant stability of only a specific region for all patients or discriminate results evaluated for each region if the analysis had been made in various regions; RFA and DCA should have been applied in the same implants and periods. Studies have been carefully selected, and data of interest were tabulated.Results: Six studies met the inclusion criteria. Although there was significant numerical correlation between values obtained by both methods, data showed that less than half (46%) of cases coincided in relation to implant stability classification.Conclusions: It can be considered that there is not always a consensus and standardization in the classification of implant stability related to the values obtained by RFA and DCA devices, which could create disagreements and miscommunication among dentistry professionals.

Published: October 2016

SummaryAs imaging and diagnostic capabilities improve, an increasing number of patients will present for complex surgical procedures requiring a multidisciplinary team approach. Atrial tumour thrombus secondary to intra‐abdominal malignancy presents major challenges for both anaesthetic and surgical management. This often requires the use of both cardiopulmonary bypass and deep hypothermic circulatory arrest. We describe the anaesthetic management of two rare intra‐bdominal sarcomas with cardiac involvement. Both patients underwent successful radical resection of sarcoma with inferior vena caval thrombectomy. We also review the available literature regarding the management of these patients.

Authors: Trindade Hugo , Silva Ronald , Rocha Teresa 
Published: October 2016

SummaryNeuraxial blockade is a useful technique in the paediatric population, particularly in cases where the risks of other anaesthetic techniques outweigh their benefits. Ultrasound‐guided approaches are becoming more popular than established classical techniques. In paediatrics, the development of new approaches to neuraxial techniques have been slow and their contribution yet to be demonstrated in prospective studies. We describe a successful case related to surgery on an infant with Crouzon syndrome, in which we used a new combined ultrasound‐guided block.

Published: October 2016

SummaryPatients with a difficult airway provide a challenge for both anaesthetists and surgeons during laryngeal surgery. We describe a novel technique in the anaesthetic management of a 58‐year‐old male with a known difficult airway who required tubeless anaesthesia for laryngeal surgery. By utilising an airway exchange catheter as an adjunct during tubeless anaesthesia, we were able to safely manage the airway and ventilation in addition to providing a tubeless surgical field. Our experience has prompted us to consider its use more frequently during laryngeal surgery where a difficult airway is anticipated or encountered.

Мета дослідження — вивчення ефективності та безпеки терапії метформіном пролонгованої дії у поєднанні з глімепіридом у хворих на цукровий діабет (ЦД) 2-го типу. Матеріали та методи. Під спостереженням перебувало 35 хворих на ЦД 2-го типу. До включення в дослідження пацієнти отримували метформін без досягнення цільових рівнів глікемії, а з моменту спостереження було додатково призначено комбіновану цукрознижувальну терапію глімепіридом і метформіном пролонгованої дії (препарат Дуглимакс, «Кусум Фарм», Україна) у поєднанні з метформіном (препарат Метамін SR, «Кусум Фарм», Україна). Лікування тривало впродовж 12 тижнів. До і після лікування оцінювали показники вуглеводного, ліпідного обміну, ступінь інсулінорезистентності та масу тіла. Результати. У проведеному дослідженні встановлений позитивний вплив комбінованої терапії метформіном і глімепіридом на вуглеводний та ліпідний обмін і загалом на показники чинників ризику розвитку серцево-судинних ускладнень (дисліпідемію, інсулінорезистентність, гіперінсулінемію). Рівень глікованого гемоглобіну порівняно з початковими значеннями знизився на 1,5 % (р < 0,05), глікемії натще — на 32,1 % (р < 0,05), постпрандіальної глікемії — на 43,7 % (р < 0,05). Крім того, на тлі терапії спостерігалося покращення ліпідного обміну: зниження загального холестерину на 16,6 % (р < 0,05), холестерину ліпопротеїнів низької щільності — на 29,7 % (р < 0,05), тригліцеридів — на 42,7 % (р < 0,001). Спостерігалося зниження рівня лептину в плазмі крові з 17,84 ± 2,3 нг/мл до 14,83 ± 2,42 нг/мл (р > 0,05). Зміни антропометричних показників (індексу маси тіла, окружності талії і стегон) були статистично незначущими (р > 0,05). На тлі комбінованого лікування не відзначалося гіпоглікемічних реакцій і побічних явищ. Висновки. Комбінована цукрознижувальна терапія метформіном пролонгованої дії і глімепіридом упродовж 12 тижнів призвела до статистично значущого покращення показників вуглеводного та ліпідного обміну.
