Biomechanical effects of continuous loop running in comparison to discontinuous runway running on locomotion and running shoe characterization

Abstract Running and running shoe biomechanics are usually measured in laboratory settings, capturing discontinuous running trials. Continuous running measured outdoors doesn’t allow comprehensive measurement equipment due to limited technology. This research compared biomechanical effects of continuous loop and discontinuous runway running on locomotion and running shoe characterisation. Twenty-two runners performed eight trials in three shoe conditions in a runway and a loop laboratory setting, while capturing ground reaction forces and lower limb kinematics. Running mode and shoe variable magnitudes and intra-participant variability, means were compared for main and interaction effects (p < 0.05) by a 2 × 3 within-participants repeated measures analysis of variance, and effect size estimation. Kinetic and kinematic variables indicated biomechanical effects induced by running mode. Continuous loop running significantly decreased ground contact time (241.31–234.47 ms), and braking force (0.37–0.35 bw). It showed a significantly flatter and inverted foot-strike at touchdown by reducing sagittal shoe ground angle (20.27–16.69°), and increasing ankle inversion angle (5.50–6.67°). Continuous loop running significantly increased intra-participant variability in ankle dorsiflexion (9.49–12.78) and maximal eversion angle (12.70–17.36). Kinetic and kinematics indicated biomechanical effects induced by running shoes, shoe classification was similar between modes. Running mode influences biomechanics, whilst shoe classification remains similar. Anterior-posterior braking force is overestimated in discontinuous runway running, combined with increased variability suggesting an inconsistent foot-strike. Variability at the ankle joint was seen to increase during continuous loop running, indicating a more rigid ankle complex during discontinuous runway running. Our findings suggest that continuous loop running should be used when precise absolute variable magnitudes are required while runway running tests appear sufficient for general comparative shoe evaluation.
La psiquiatría de enlace y el diagnóstico del delirium tremens

Introducción Los síntomas de abstinencia aparecen cuando una persona con dependencia de alcohol disminuye o interrumpe por completo el consumo. Muchos individuos con dependencia de alcohol subestiman su problema. Con frecuencia, estos pacientes presentan síntomas de abstinencia cuando son internados debido a una enfermedad física y deben forzadamente dejar de beber. Cerca del 16% al 25% de las personas hospitalizadas debido a problemas médicos, y entre el 40% y el 50% de las que concurren a los servicios de emergencias presentan abuso o dependencia de alcohol. A su vez, aproximadamente la mitad de los pacientes con dependencia de alcohol (entre el 13% y el 71%) presentan síntomas de abstinencia clínicamente significativos; en consecuencia, la prevalencia de abstinencia de alcohol en individuos hospitalizados debido a problemas médicos es del 15% al 20%. La prevalencia de dichos síntomas es mayor en los servicios de agudos, como los de emergencias y traumatología o la unidad de cuidados intensivos (UCI), y varía entre el Abstract The most serious and potentially life-threatening manifestation of alcohol withdrawal is delirium tremens (DT) or alcohol withdrawal delirium, which occurs in about 5% to 10% of hospitalized patients with alcohol problems. A consideration of risk factors, the typical clinical picture, evolution of withdrawal-symptoms and their severity aid in the proper recognition of DT. Benzodiazepines are the mainstay of medication treatment of DT. Their efficacy has been established by a large body of evidence. Although alternative medications might be equally effective, benzodiazepines are preferred because of their favourable pharmacokinetic and safety. Alternative medications are used as adjuncts to benzodiazepines in the treatment of complicated and refractory withdrawal states. Oral or intravenous loadingdose regimens are preferred for treatment of DT. Rapidly escalating doses of benzodiazepines titrated to symptom-severity on structured scales and the use of adjunctive alternative medications ensures prompt control of DT. About 10% of patients who are benzodiazepine-resistant require treatment in intensive care units with massive intravenous doses of benzodiazepines and additional medications, careful monitoring and mechanical ventilation if necessary. Vitamin supplementation and adequate medical, nursing and supportive care are other essential components of management. Liaison psychiatrists are expected to form an integral part of the multidisciplinary team, which manages patients with DT in acute-care settings. Only skilled and knowledgeable liaison psychiatrists relying on standardized treatment protocols can make certain that patients with DT receive adequate care. The liaison psychiatrist also needs to ensure a safe and humane withdrawal that protects the patient’s dignity and prepares the patient for on-going treatment of dependence.
Did the introduction of High-Sensitivity Troponin T for the assessment of suspected acute coronary syndrome in Malta result in reduction of hospitalization time? A retrospective review

Aims: Troponins I and T are biomarkers used for diagnosing myocardial infarction. The recently developed high-sensitivity Troponin T assay can detect levels as low as 3 ng/L which gives the advantage of rapid diagnosis of acute coronary syndrome (ACS) allowing earlier intervention and theoretically earlier discharge. The aim of the study was to audit the hospital practice and its adherence to international guidelines in using Troponin for diagnosing ACS, and to assess the average hospital admission length when using Troponin T compared to the older Troponin I. Methodology: A retrospective study that included all patients who had Troponin T taken between January 1st and January 31st, 2016 at Mater Dei Hospital (MDH), comparing them to patients who had Troponin I taken between November 1st and November 30th, 2015. Results: Data collection yielded a total of 1,032 patients in the Troponin T group and 1,004 patients in the Troponin I group. The average length of stay when using Troponin T was 5.53 days whereas the average length of stay when using Troponin I was 8.29 days. Data analysis of those patients also showed that the average time interval between the first and second Troponin was in the region of 9 hours, which is not what the current guidelines recommend. Conclusion: The use of the new highly sensitive Troponin T resulted in an average reduction in hospitalization time of 2.76 days per patient at MDH. Adherence to the “0/3 hours” guideline of the second Troponin is highly recommended.
Serum zinc level and its relation to insulin resistance and lipid profile in childhood and adolescent obesity

Background Obesity is considered to be a worldwide health problem. Obese individuals are at a high risk of developing dyslipidemia, hypertension, impaired glucose tolerance, insulin resistance, and consequent increase of the risk of metabolic and cardiovascular diseases. In obesity, elevated insulin resistance is observed, which may be associated with disturbances in zinc status in the body. The few studies concerning the status of zinc and its relationship with insulin resistance in obese children and adolescents have brought inconclusive results. Aims The aims of this work were to study the level of serum zinc in obese children and adolescents and to evaluate its potential relation to obesity, insulin resistance, and lipid profile. Patients and methods Thirty obese children and adolescents and 30 healthy controls aged 5–19 years were recruited for the study. Lipid profile, serum zinc, fasting plasma glucose, and fasting insulin were measured. Insulin resistance was calculated according to the homeostatic model of assessment for insulin resistance and quantitative insulin-sensitivity check index. Results Obese individuals had significantly higher serum triglycerides, total cholesterol, low-density lipoprotein cholesterol, fasting plasma glucose, fasting blood insulin, and homeostatic model of assessment for insulin resistance, whereas high-density lipoprotein cholesterol and quantitative insulin-sensitivity check index were significantly lower in obese children than in healthy controls (all P<0.05). The serum concentration of zinc was significantly lower in obese individuals compared with control. There was a positive significant correlation between serum zinc level and high-density lipoprotein (r=0.511, P<0.05). Conclusion Obese children and adolescents have a poorer zinc status than children and adolescents of normal weight, which may affect lipid profile.
Experimental Demonstration of AoA Estimation Uncertainty for IoT Sensor Networks

In practice, the subspace-based algorithms such as Multiple Signal Classification (MUSIC) suffer from sensitivity to antenna-array response errors and therefore they require the assessment of the calibration gain and phase perturbations. This paper evaluates experimentally the accuracy of Angle-of-Arrival (AoA) estimation based on the MUSIC algorithm only coming from these perturbations in the context of Internet-of-Thing (IoT) applications. First of all, a new Over-the-Air (OTA) calibration method is proposed and gain and phase uncertainties are investigated. The impact of these uncertainties on the accuracy of AoA estimation is then studied and compared with the theoretical analysis. The experimental results show that the calibration errors coming from hardware imperfections can cause some degrees of uncertainty in AoA estimation.

Time–Frequency Attribute Analysis of Channel 1 Data of Lunar Penetrating Radar

The Lunar Penetrating Radar (LPR) carried by the Chang’E-3 (CE-3) and Chang’E-4 (CE-4) mission plays a very important role in lunar exploration. The dual-frequency radar on the rover (DFR) provides a meaningful opportunity to detect the underground structure of the CE-3 landing site. The low-frequency channel (channel 1) maps the underground structure to a depth of several hundred meters, while the high-frequency channel (channel 2) can observe the stratigraphic structure of gravel near the surface. As the low-frequency radar image is troubled by unknown noise, time–frequency analysis of a single trace is applied. Then, a method named complete ensemble empirical mode decomposition (CEEMD) is conducted to decompose the channel 1 data, and the Hilbert transform gives us the chance for further data analysis. Finally, combined with regional geology, previous studies, and channel 2 data, a usability analysis of LPR channel 1 data provides a reference for the availability of the CE-4 LPR data.
A Gamification and Avatar Self-representation Application for Diabetes Self-management

Diabetes affects a person’s lifestyle, in particular, their nutrition intake, daily activities, and exercise. Individuals with diabetes are encouraged to learn more about their condition. This will help them to control and manage diabetes and thus, nurturing self-management. Introducing gamification for diabetes, using a gamified avatar as self-representation to reflect the patient’s condition may offer different experiences in learning about the disease. In this study, we describe the gamification design applications that integrate games and the patient’s avatar for learning about diabetes that could help them to self-manage. We report our preliminary study on implementing the user experience approach, in evaluating the designs of the application. The study revealed that the gamified designs are considered suitable for diabetes self-management, however, there are still some concerns about the reality of the avatar reflection. We discuss challenges and suggestions for further research and implementation in the development of pervasive avatar gamified applications.

Effectiveness Undersampling Method and Feature Reduction in Credit Card Fraud Detection

: Credit card fraud is an issue that has affected Indonesia payment system over a decade. Sometimes, the result of the fraud used for terrorism and other crimes. Financial loss is not the only problem that is affected caused by credit card fraud but also Indonesia images in international trade, e-commerce, and the merchant. Currently, a trusted and secured banking payment system is crucial for both customers and banks. The problem from credit card fraud dataset is the data have many features and imbalanced class, this problem leads the paper to propose undersampling technique and feature reduction methods. In this paper we proposed two stage-feature reduction technique because a stage feature reduction could not find the optimal features. On the other hands, we are also applied Instance Hardness Threshold sampling and Random undersampling to deal with imbalance data. The two-stage feature reduction is chosen to eliminate the ineffective feature that cannot eliminate using only one feature reduction. The model from the implemented machine learning methods is evaluated using accuracy, specificity, recall, and Matthews Correlation Coefficient. We implemented our proposed approaches in the ULB credit card fraud detection dataset. According to the result, the undersampling gives a boost in performances which improve the recall and MCC score, the IHT undersampling provide goods results, and in some cases, the result can predict all the test set correctly. However, the two-stages feature reduction fails to improve the accuracy, precision, recall, and MCC score. In one case, the method reduced the accuracy score to 0.302.

Maintain situation awareness in semi-autonomous driving with a haptic seat

Semi-autonomous driving is rapidly evolving and one of its major issues is the reduction of the driver's attention to his/her environment. After a brief study of current interactions increasing this situational awareness, and more particularly haptic interactions, this article proposes the use of vibrations in the seat. Vibrations, due to their location and variations in frequency and amplitude, make it possible to convey different information to the driver such as the position of obstacles around his/her vehicle as well as the state of deterioration of the road markings. The results of initial exploratory tests are promising on the use of haptic interactions. They make it possible to set up the design and procedure for future experiments.
Acute Myocardial Infarction after MaxMan Consumption with Normal Angiography: A Case Report

Acute myocardial infarction (MI) with a normal coronary angiogram is a well established abnormality, although it is usually related with stenosis in coronary arteries. We reported here a case of a 24-year-old man referring with acute inferior MI after MaxMan capsule consumption. The patient had not any related risk factors of coronary artery disease and a history of prior MI. The acute inferior infarction in this patient was detected in the electrocardiogram in the absence of any stenosis or obstruction in the angiogram. We do not recommend MaxMan intake as a usual drug before intercourse.
Noninvasive Assessment of Coronary Flow Reserve Before and After Ranolazine Administration: Does It Improve in Our Real Patients?

Background: Myocardial ischemia may be caused by microvascular disease. The ratio of the maximal possible coronary blood flow to the resting coronary blood flow is termed “the coronary flow reserve” (CFR), which may be assessed noninvasively via dipyridamole stress echocardiography (DSE). Ranolazine is an anti-ischemic agent whose effect on the coronary flow is poorly known. Purpose: We sought to assess temporal variations in the CFR after and before ranolazine administration in a real clinical practice setting among patients with angina and non-obstructive epicardial coronary artery disease. Methods: Seven patients were enrolled, and their demographic, electrocardiographic, and laboratory data were recorded. The CFR was calculated in the anterior descending coronary artery. The definition of abnormal microcirculation was a cutoff value under 2.5. Treatment lasted for 3 months, after which time the same response variables as before were recorded. A general linear model was used to assess whether there was a difference between the preand post-administration of ranolazine. Results: Seven patients were evaluated. At follow-up, there was no discontinuation or side effect. The CFR significantly increased with time (F1,6 = 6.909; P = 0.039). Initially, the mean (± 1 SD) value was 1.85 (±0.34), which rose up to 2.21 (±0.31) after the 3-month treatment period. Conclusions: Ranolazine might have beneficial effects on the CFR as assessed by DSE in patients with angina and non-obstructive epicardial coronary artery disease.
Nekrotisierende Parodontalerkrankungen – eine neue therapieabhängige Klassifikation

Nekrotisierende Parodontalerkrankungen stellen eine eigene Entität (Subkategorie V) in der aktuellen Klassifikation parodontaler Erkrankungen und Zustände dar. Formal wird zwischen nekrotisierender ulzerierender Gingivitis (NUG) und nekrotisierender ulzerierender Parodontitis (NUP) differenziert. Nach der Klassifikation stellt die NUG eine Infektion dar, die durch gingivale Nekrosen charakterisiert ist. Diese imponieren als ausgestanzte Papillen, wohingegen die Nekrosen bei der NUP auf das Desmodont und den Alveolarknochen extendiert sind [1]. Eine klare Abgrenzung dieser beiden Erkrankungsformen ist in einigen Fällen jedoch nicht möglich. ▶ Abb. 1 zeigt ein klinisches Foto eines Patienten, der auf dem Boden einer bestehenden generalisierten chronischen Parodontitis nekrotische Areale entwickelt hat. Es ist hier nicht zu differenzieren, ob der Attachmentverlust entzündungsbedingt aus der chronischen Parodontitis oder aus dem nekrotischen Zerfall von Desmodont und Alveolarknochen resultiert.
Impact of structural and interpersonal components of health care on user satisfaction with services of an outpatient clinic of a Nigerian tertiary hospital

Background: Patient satisfaction plays a key role in health-care reforms and service delivery. It is determined by patient's perception of the structural, interpersonal, and technical components of care. With current efforts toward universal coverage, government-owned National Health Insurance Scheme (NHIS)-accredited health facilities may need to improve the structural and interpersonal aspects of patients' care to survive in the emerging competitive health-care industry in Nigeria. Materials and Methods: A cross-sectional study of 220 NHIS enrollees randomly selected from patients attending the Staff Clinic of Aminu Kano Teaching Hospital Kano assessed patients' satisfaction with the structural (service-window-locations, cleanliness, adequacy of seats and toilets, and staff sufficiency) and interpersonal (staff friendliness, communication, respectfulness, response-to-requests, and efficiency) components of care as well as overall clinic satisfaction using a modified general practice assessment questionnaire. Results: Most of the respondents (65.9%) were satisfied with the clinic services. Respondents' satisfaction with the clinic's cleanliness, ease in locating medical records' unit and retrieving laboratory results, adequacy of doctors, friendly/respectful and responsive cashiers and clinical assistants (CAs), receiving satisfactory explanation on how to use prescribed drugs and unavailable drugs were all associated with the overall clinic satisfaction. However, cashiers' efficiency (odds ratio [OR] = 6.5, P = 0.006) and CAs' responsiveness (OR = 5.0, P = 0.03) were the predictors of overall satisfaction. Conclusion: Improvements in patients' overall satisfaction with the clinic services may require increasing the proportion of patients satisfied with the cashiers' efficiency and CAs' responsiveness (or those with similar roles) in service delivery.
