The influence of cardiac rehabilitation according to the C model on exercise tolerance and hemodynamic indices in patients after cardiac incident

Background and Study Aim: Cardiovascular diseases are currently classified as civilization diseases. The number of cases since the 20th century has dramatically increased. Currently, as many as 46% of all deaths in Poland are caused by diseases of the circulatory system. The aim of the study is to assess the impact of cardiac rehabilitation according to the C model on exercise tolerance and hemodynamic indices in patients after a cardiac incident. Material and Methods: The research was carried out in the Department of Cardiac Rehabilitation in Szymbark. The study group consisted of 32 patients who, after physical examination at admission, were qualified for the preliminary assessment of physical fitness on the basis of 6MWT. The test was carried out the day after the admission, according to current standards. Subsequently, the examined persons underwent a 28-day cycle of early cardiac rehabilitation according to the C model. Results: As a result of a 4-week cardiac rehabilitation, a statistically significant improvement in physical performance was obtained, with a distance increase of 68.34 m on average. A statistically significant change in the level of fatigue according to Skala Borga after the completion of the rehabilitation cycle was demonstrated. Patients with normal body weight, overweight and obesity received a similar increase in 6MWT results due to the rehabilitation cycle. Conclusions: The results of this study indicate the urgent need to educate patients in the prevention and prevention of cardiovascular disease and to increase the availability of rehabilitation for all people after a cardiological incident.

The Impact

Introduction.Methanol and its derivatives occupy one of the leading places among the main organic synthesis intermediates in terms of their importance and scale of production. According to experts, by 2027 the global demand for methanol can reach 135 million tons, the annual growth will be about 5.5%. However, there is little information regarding the assessment of working conditions and occupational risks for workers in modern methanol production and its derivatives.The aim of the studyis hygienic assessment of working conditions and the formation of health risks in workers of modern production of methanol and methylamines.Materials and methods.The assessment of the main adverse factors of production is given. When studying the state of health, objective indicators (the results of an in-depth medical examination) and subjective (the results of a quantitative assessment of the risks of the main pathological syndromes associated with health) are considered.Results.According to long-term observations, the concentration of harmful substances in the air of the working area, indicators of labor severity, parameters of physical factors met hygienic requirements, with the exception of industrial noise exceeding the maximum permissible level, as well as labor intensity of 1 degree. The General assessment of working conditions corresponds to the category of harmful 2 degrees (3.2). According to the results of the medical examination and quantitative assessment of the risks of health disorders in workers, the most significant were functional disorders and diseases of the circulatory system. The levels of somatic pathology on the part of the main body systems were significantly higher in apparatchiks compared to the engineering and technical personnel (ETP).Conclusions:In the production of methyl alcohol and methylamines, the main hygienic importance is the impact on workers of the complex of harmful substances of 1-IV hazard classes in low concentrations, increased levels of industrial noise, labor intensity of 1 degree. According to the subjective assessment of health and medical examination, the greatest prevalence of health risks in workers was observed from the circulatory system, and the levels of the revealed somatic pathology were statistically significantly higher in apparatchiks compared with the ETP.

The paper presents a numerical modeling study aimed at a preliminary assessment of the impact of the planned sea outfall of the city of Limassol, Cyprus, on the waters of Akrotiri bay. First the local meteorological and oceanographic conditions as well as the loading characteristics are briefly reviewed. Two-dimensional finite element hydrodynamic and dispersion models are subsequently applied to the study area. The results of the former show an eastbound flow pattern under the prevailing westerly winds, in general agreement with available field observations. The spread of BOD and N under continuous loading is then examined for eastward as well as for westward flow as an indicator for the extent of pollution to be expected. The computed concentrations are generally low and confined to the shallower parts of the bay.

Abstract Funding Acknowledgements Type of funding sources: None. Introduction A number of randomized controlled trials have examined the effect of exercise training on left ventricle (LV) remodeling in individuals with cardiovascular disease. However, the results of these trials have been inconclusive. Purpose Evaluation of the impact of a cardiac rehabilitation program (CRP) on left ventricle remodelling evaluated by echocardiogram. Methods Observational single centre study including consecutive patients, undergoing structured CRP since June 2016 until February 2020. Phase II CRP included 3 months of exercise training, aerobic and strength exercise, individually prescribed, 3 times a week, 60 minutes sessions. All patients were submitted to a clinical evaluation, echocardiogram, and cardiopulmonary exercise test before and after the CRP. Results 205 patients (62.6 ± 11 years, 83.4% men, 82.3% ischemic disease) were included in a phase II CRP. Most patients had ischemic disease (82.3%) and 23.5% of patients had left ventricular ejection fraction (LVEF) <40%. Of the cardiovascular risk factors, hypertension was the most prevalent (76%), followed by dyslipidaemia (67.4%), active smoking (45.9%) and diabetes (26.9%). After the CRP, there was a significant improvement of LVEF (from 48.3 ± 13 to 52 ± 11.6 %, p = 0.001) and a significant reduction of LV volumes (LV end-diastolic volume, LVEDV , decreased from 140 ± 81 to 121 ± 57, p = 0.002; LV end-systolic volume , LVESV , reduced from 80 ± 75 to 64 ± 48, p = 0.004). Considering only the patients with LVEF < 40% (n = 38), the improvement was even greater: LVEF increased from 30 ± 8 to 39 ± 13 (p = 0.002); LVEDV reduced from 206 ± 107 to 159 ± 81 (p = 0.001) and LVESV reduced from 142 ± 99 to 101 ± 66 (p = 0.002). 63.6%(n = 14) of these patients improved at least 10% of LVEF and only 1 of them had a cardiac resynchronization therapy device. Conclusions A phase II CR program was associated with significant improvements in left ventricular reverse remodelling irrespective of baseline EF classification. Those with reduced baseline EF derived an even greater improvement, highlighting the great importance of CR in this subgroup of patients.

Over Time

The growth status and weight status of Chinese children have experienced remarkable changes in the past decades. Using China Health and Nutrition Survey (CHNS) data, this paper examines the secular trends and disparity of the growth status and weight status in Chinese children and further investigates the impact of various family environments on children’s growth from 1991 to 2011. We found an increasing trend in standardized growth indicators (height, weight, and BMI), overweight, and obesity from 1991 to 2011. We also observed an increasing disparity in overweight and obesity over time. Family environments had a significant impact on children’s growth status and weight status. In particular, children that live in families with a small size, higher family income, better sanitary conditions, and with well-educated parents or overweight parents tended to be taller and heavier and have a higher BMI, lower risk of being underweight, and higher risk of exhibiting overweight and obesity. Further decomposition analysis showed that more than 70% of the disparity in standardized height, weight, and overweight and around 50% of the disparity in standardized BMI, underweight, and obesity could be attributed to heterogeneity in family environments. Moreover, the disparity associated with family environments tended to increase over time.

AbstractThe severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) pandemic has proven a challenge to healthcare systems since its first appearance in late 2019. The global spread and devastating effects of coronavirus disease 2019 (COVID-19) on patients have resulted in countless studies on risk factors and disease progression. Overweight and obesity emerged as one of the major risk factors for developing severe COVID-19. Here we review the biology of coronavirus infections in relation to obesity. In particular, we review literature about the impact of adiposity-related systemic inflammation on the COVID-19 disease severity, involving cytokine, chemokine, leptin, and growth hormone signaling, and we discuss the involvement of hyperactivation of the renin-angiotensin-aldosterone system (RAAS). Due to the sheer number of publications on COVID-19, we cannot be completed, and therefore, we apologize for all the publications that we do not cite.

Background: One of the great challenges facing today’s society is the need to combat overweight and obesity in schoolchildren. This study aimed to analyze the impact of a cycle of didactic talks—given to families by a specialist in pediatrics, a specialist in nutrition and dietetics and a specialist in physical exercise—on childrens’ snack choices and nutrition quality. Methods: A longitudinal, quasi-experimental and quantitative investigation was designed, working with a total sample of 50 students divided into control and experimental groups. The nutritional quality of daily snacks was recorded during the month before and the month after the cycle of talks given by health experts. Results: An increase in the nutritional quality of the snacks was observed in the days after the talk—but, after a week, values returned to normal. Conclusions: The giving of educational talks to promote healthy habits may have a positive impact on the nutritional quality of school snacks in the days immediately following the talks. However, some forgetfulness was detected over time, which reduced the nutritional quality of the snacks once more. For future work, it is recommended that researchers measure the impact produced by giving regular talks.

Abstract Background To evaluate the short- and mid-term effect of a specially tailored resistance and balance training provided in addition to usual cardiac rehabilitation (CR) care program in older patients after valve surgery/intervention. Methods Single-center (inpatient CR clinic in Lithuania) randomized controlled trial. Two hundred fifty-two patients were assessed for eligibility on the first day of admittance to CR early after (14.5 ± 5.9 days) valve surgery/intervention between January 2018 and November 2019. Participants were coded centrally in accordance with randomization 1:1 using a computerized list. Control group (CG) patients were provided with usual care phase-II-CR inpatient multidisciplinary CR program, while intervention group (IG) patients received additional resistance and balance training (3 d/wk). Patients participated in a 3-month follow-up. Main outcome measures were functional capacity (6 min walk test (6MWT, meters), cardiopulmonary exercise testing), physical performance (Short Physical Performance Battery (SPPB, score) and 5-m walk test (5MWT, meters/second)), strength (one repetition maximum test for leg press), physical frailty (SPPB, 5MWT). Results One hundred sixteen patients (76.1 ± 6.7 years, 50% male) who fulfilled the study inclusion criteria were randomized to IG (n = 60) or CG (n = 56) and participated in CR (18.6 ± 2.7 days). As a result, 6MWT (IG 247 ± 94.1 vs. 348 ± 100.1, CG 232 ± 102.8 vs. 333 ± 120.7), SPPB (IG 8.31 ± 2.21 vs. 9.51 ± 2.24, CG 7.95 ± 2.01 vs. 9.08 ± 2.35), 5MWT (IG 0.847 ± 0.31 vs. 0.965 ± 0.3, CG 0.765 ± 0.24 vs 0.879 ± 0.29) all other outcome variables and physical frailty level improved significantly (p < 0.05) in both groups with no significant difference between groups. Improvements were sustained over the 3-month follow-up for 6MWT (IG 348 ± 113 vs. CG 332 ± 147.4), SPPB (IG 10.37 ± 1.59 vs CG 9.44 ± 2.34), 5MWT (IG 1.086 ± 0. 307 vs CG 1.123 ± 0.539) and other variables. Improvement in physical frailty level was significantly more pronounced in IG (p < 0.05) after the 3-month follow-up. Conclusion Exercise-based CR improves functional and exercise capacity, physical performance, and muscular strength, and reduces physical frailty levels in patients after valve surgery/intervention in the short and medium terms. SPPB score and 5MWT were useful for physical frailty assessment, screening and evaluation of outcomes in a CR setting. Additional benefit from the resistance and balance training could not be confirmed. Trial registration NCT04234087, retrospectively registered 21 January 2020.

The Impact

Abstract Physical exercise training and medication compliance are primary components of cardiac rehabilitation. When rehabilitating independently at home, patients often fail to comply with their prescribed medication and find it challenging to interpret exercise targets or be aware of the expected efforts. Our work aims to assist cardiac patients in understanding their condition better, promoting medication adherence and motivating them to achieve their exercise targets in a tele-rehabilitation setting. We introduce a patient-centric intelligible visualization approach to present prescribed medication and exercise targets to patients. We assessed efficacy of intelligible visualizations on patients’ comprehension in two lab studies. We evaluated the impact on patient motivation and health outcomes in field studies. Patients were able to adhere to medication prescriptions, manage their physical exercises, monitor their progress and gained better self-awareness on how they achieved their rehabilitation targets. Patients confirmed that the intelligible visualizations motivated them to achieve their targets better. We observed an improvement in overall physical activity levels and health outcomes of patients. Research Highlights Presents challenges currently faced in cardiac tele-rehabilitation. Demonstrates how intelligibility was applied to two core aspects of cardiac rehabilitation- promoting medication adherence and physical exercise training. Lab., field and clinical studies to demonstrate efficacy of intelligible visualization, impact on patient motivation and resultant health outcomes. Reflection on how similar HCI approaches could be leveraged for technology-supported management of critical health conditions such as cardiac diseases.

And Oxidative Stress

Vascular endothelium plays a vital role in the organization and function of the blood vessel and maintains homeostasis of the circulatory system and normal arterial function. Functional disruption of the endothelium is recognized as the beginning event that triggers the development of consequent cardiovascular disease (CVD) including atherosclerosis and coronary heart disease. There is a growing data associating mercury exposure with endothelial dysfunction and higher risk of CVD. This review explores and evaluates the impact of mercury exposure on CVD and endothelial function, highlighting the interplay of nitric oxide and oxidative stress.
