Abstract Background The assessment of improvement or maintenance of joint health in healthy subjects is a great challenge. The aim of the study was the evaluation of a joint stress test to assess joint discomfort in subjects with activity-related knee joint discomfort (ArJD). Results Forty-five subjects were recruited to perform the single-leg-step-down (SLSD) test (15 subjects per group). Subjects with ArJD of the knee (age 22–62 years) were compared to healthy subjects (age 24–59 years) with no knee joint discomfort during daily life sporting activity and to subjects with mild-to-moderate osteoarthritis of the knee joint (OA, Kellgren score 2–3, age 42–64 years). The subjects performed the SLSD test with two different protocols: (I) standardization for knee joint discomfort; (II) standardization for load on the knee joint. In addition, range of motion (ROM), reach test, acute pain at rest and after a single-leg squat and knee injury, and osteoarthritis outcome score (KOOS) were assessed. In OA and ArJD subjects, knee joint discomfort could be reproducibly induced in a short time interval of less than 10 min (200 steps). In healthy subjects, no pain was recorded. A clear differentiation between study groups was observed with the SLSD test (maximal step number) as well as KOOS questionnaire, ROM, and reach test. In addition, a moderate to good intra-class correlation was shown for the investigated outcomes. Conclusions These results suggest the SLSD test is a reliable tool for the assessment of knee joint health function in ArJD and OA subjects to study the improvements in their activities. Further, this model can be used as a stress model in intervention studies to study the impact of stress on knee joint health function.

Abstract Objective: To evaluate the impact of two original compositions of polyphenols-containing dietary supplement on lipid profile and level of C-reactive protein (CRP) in patients with angiographycally verified coronary artery disease (CAD). Design and methods: 167 patients were selected during their scheduled post-event elective bicycle stress-test examination. All patients received standard CAD therapy and permanent statin therapy and had elevated total cholesterol (TC > 5.0 mmol/L) and/or CRP (>3.5 mg/L) levels. The study consisted of 2 days of polyphenol depletion followed by a 12-week supplementation period in a randomized, blinded, placebo-uncontrolled parallel design. Two different compositions SILVA 1 (Quercetine, linseed oil and Resveratrol), and SILVA 2 (Quercetine, linseed oil and Pycnogenol) were tested. Results: All parameters changed compared baseline and 1 and 3 months in both groups. CRP decreased from 2.48 ± 1.62 mg/L at baseline to 1.97 ± 1.15 mg/L, high density cholesterol (HDL-C) increased from 1.18 ± 0.31 to 1.38 ± 0.34 mmol/L, also decrease of triglycerides (TG) from 1.5 to 1.29 mmol/L after 3 months treatment in SILVA I group was statistically significant (p < 0.001). Changes of parameters between baseline and 1 or 3 months in SILVA II group were not statistically significant. Hovewer, decrease of CRP (from 2.6 ± 1.28 to 2.41 ± 1.68), decrease of low density cholesterol (LDL-C from 2.95 ± 1.2 to 2.88 ± 1.21), increase of HDL-C (from 1.25 ± 0.22 to 1.34 ± 0.23), decrease of TC (from 5.2 ± 1.3 to 5.1 ± 1.28) and decrease of TG (from 1.4 ± 0.41 to 1.3 ± 0.38) can be counted as tendency of changes. Conclusion: This study reveals the superiority of treatment with statins in combination with composition containing Resveratrol for correction of lipid profile and inflamation marker CRP of patients with CAD

The Impact

The panel performance of a prefabricated cabin-type substation under the impact of fires plays a vital role in the normal operation of the substation. However, current evaluations of the panel performance of substations under fire still focus on fire resistance tests, which seldom consider the relationship between fire behavior and the mechanical load of the panel under the impact of fires. Aiming at the complex and uncertain relationship between the thermal and mechanical performance of the substation panel under impact of fires, this paper proposes a machine learning method based on a BP neural network. First, the fire resistance test and the stress test of the panel is carried out, then a machine learning model is established based on the BP neural network. According to the collected data, the model parameters are obtained through a series of training and verification processes. Meanwhile, the correlation between the panel performance and fire resistance was obtained. Finally, related parameters are input into the thermal–mechanical coupling evaluation model for the substation panel performance to evaluate the fire resistance performance of the substation panel. To verify the correctness of the established model, numerical simulation of the fire test and stress test of the panel is conducted, and numerical simulation samples are predicted by the trained model. The results show that the prediction curve of neural network is closer to the real results compared with the numerical simulation, and the established model can accurately evaluate the thermal–mechanical coupling performance of the substation panel under fire.

AbstractChronic stress is associated with impacting eating behavior, namely food choice and energy intake, with a shift towards more palatable and energy dense foods. Additionally, eating behavior is influenced by other psychological factors like mood and emotions. The categorization of people into eating types such as restrained, emotional, and external eaters has gained attraction. Reported changes in eating behavior due to psychological stress are only occasionally accompanied by measures of physiological hunger through ghrelin. The primary objective of this study was to investigate how chronic stress and acute cortisol reactivity affect active ghrelin secretion and how these outcomes account for different eating types. 16 healthy, young males (age: 23 ± 3 years, BMI: 22.5 ± 1.3kg/m2) with low (n = 8) and average-to-high (n = 8) chronic stress level were subjected to the Trier Social Stress Test (TSST) and a control version on two separate days. Active ghrelin, cortisol, glucose, and heart rate were measured throughout the test. Subjects rated their hunger by means of visual analog scale and current mood was assessed with the Positive and Negative Affect Scale (PANAS). In addition, participants filled out the Dutch Eating Behavior Questionnaire (DEBQ) to account for their subjective eating behavior. Overall ghrelin values where higher on the test day compared to the control day. Ghrelin values were also higher during the time leading up to the stress or control test (TSST) than during the conclusion of said tests. On both days, mean values for active ghrelin where higher in individuals with low chronic stress exposure compare to those with average-to-high chronic stress exposure. While values from test to control day decreased for lower stressed participants, they slightly increased for higher stressed participants. Cortisol responders displayed higher ghrelin values on test day than cortisol non-responders, but this association inverted for the control day. Results indicate that chronic stress influences acute stress response and further alters active ghrelin production, which in turn can influence eating behavior. Replication in a greater group of participants of differing weight and sex could yield a greater understanding of stress induced eating. Factors such as relaxation techniques and coping mechanisms could further improve our knowledge and evaluate treatment possibilities.

The Impact

Weather variables are an important driver of power generation from renewable energy sources. However, accurately predicting such variables is a challenging task, which has a significant impact on the accuracy of the power generation forecasts. In this study, we explore the impact of imperfect weather forecasts on two classes of forecasting methods (statistical and machine learning) for the case of wind power generation. We perform a stress test analysis to measure the robustness of different methods on the imperfect weather input, focusing on both the point forecasts and the 95% prediction intervals. The results indicate that different methods should be considered according to the uncertainty characterizing the weather forecasts.

The Impact

This paper is an attempt to empirically examine the impact of Basel Accord regulatory guidelines on the risk-based capital adequacy regulation and bank risk management of Vietnamese commercial banks. Our research aims to assess how Vietnamese commercial banks manage their capital ratio and bank risk under the latest Basel Accord capital adequacy ratio requirements. Building on previous studies, this research uses a simultaneous equation modeling (SiEM) with three-stage least squares regression (3SLS) to analyze the endogenous relationship between risk-based capital adequacy standards and bank risk management. A year dummy variable (dy2013) is included in the model to take account of changes in the regulation of the Vietnamese banking system. Furthermore, we add a value-at-risk variable developed by as an independent variable into equations of the empirical models. The results reveal a significant impact of Basel capital adequacy regulatory pressure on the risk-based capital adequacy standards and bank risk management of Vietnamese commercial banks. Moreover, banks under the latest Basel capital adequacy regulations are induced to reduce risks and increase banks’ financial performance.

The Impact

Valvular heart disease affects 1%–2% of young individuals, many of whom aspire to partake in competitive sport or high intensity recreational exercise. There are limited reports on the impact of intensive physical activity on the progression of valvular heart disease; therefore, current recommendations are based on consensus opinion. The management of exercising individuals with valvular heart disease requires a structured approach that incorporates several key factors including symptomatic status, functional capacity, type and nature of the valvular lesion, impact on ventricular structure and function and effect on pulmonary artery pressure. Asymptomatic individuals with minor valvular abnormalities may engage in all forms of competitive sport, whereas those with lesions of moderate severity may exercise intensively if an exercise stress test tailored to the relevant physical activity reveals good functional capacity without myocardial ischaemia, haemodynamic disturbances or arrhythmia. Symptomatic athletes and those with severe valvular heart disease, impaired ventricular function, pulmonary hypertension and arrhythmias should refrain from most competitive sports. Athletes with a bicuspid aortic valve and aortic root diameter >40 mm should avoid sport with a strong isometric component even with minimal valvular dysfunction. There is an association between mitral valve prolapse and sudden cardiac death in the general population; however, there is limited evidence of increased risk with competitive sport. Athletes undergoing corrective surgery may return to exercise after 3 months if ventricular function and exercise capacity are preserved. Individuals anticoagulated for mechanical bioprosthetic valves should avoid contact or collision sport to minimise the risk of bleeding.
