Sudden Cardiac Death in Young Athletes: Screening and Risk Indicators | Chapter 19 | New Frontiers in Medicine and Medical Research Vol. 3

Background: Sudden cardiac death (SCD) during physical activity in athletes is uncommon. SCD in a young athlete is a terrible event that is the biggest medical cause of death in this population. The exact prevalence of SCD in young athletes has been a source of contention, with studies reporting widely disparate rates (1:917,000 AYs to 1:3000 AYs) depending on the methodological design of the study or the demographic studied.

The goal of this study was to assess the warning signals of SCD in young athletes and compare them to electrocardiographic data.

Methods: This was a prospective case-control study comparing athletes to inactive people. Resting electrocardiography and the Sudden Cardiac Death Screening of Risk Factors (SCD-SOS) questionnaire were used.

The overall number of participants was 898, with 589 (65.6%) in the case group (athletes) and 309 (34.4%) in the control group (sedentary). Athletes had considerably fewer fainting episodes (odds ratio 0.252, p0.001). There were no significant differences in heart rates. Sinus arr was the most prevalent electrocardiographic finding.

Conclusion: Risk markers for sudden cardiac death were shown to be less common in young athletes. There was a link between the duration of the QRS complex and the number of athletes that fainted. SCD is the main cause of death in athletes while they are exercising, and it is usually caused by intrinsic heart abnormalities precipitated by the physiologic demands of strenuous exercise. SCD rates are now at least 4 to 5 times higher than previously thought, with men, African Americans, and male basketball players being the most vulnerable. According to new evidence, the most common finding in athletes with SCD is a structurally normal heart (autopsy-negative sudden inexplicable death).

Greening Regional Airports: A Vision for Carbon Neutral Infrastructure | Chapter 12 | Contemporary Perspective on Science, Technology and Research Vol. 3

 This study provides an overview of the energy demand of a regional airport, divided into individual time horizons. The electrification of aircraft systems raises the question of whether airports will be among the largest electricity consumers in our infrastructure in the future. Sustainability and especially emission reductions are significant challenges for airports that are currently being addressed. The Clean Sky 2 project GENESIS addresses the environmental sustainability of hybrid-electric 50-passenger aircraft systems in a life cycle perspective to support the development of a technology roadmap for the transition to sustainable and competitive electric aircraft systems. This article originates from the GENESIS research and describes various options for ground power supply at a regional airport. Potential solutions for airport infrastructure with a short (2030), medium (2040), and long (2050) time horizon are proposed. In addition to the environmental and conservation benefi...

Study on Processing Method Influences the Effect of Cassava (Manihot esculenta) Consumption on Blood Lipid Profile in Rats | Chapter 8 | Current Research and Development in Chemistry Vol.1

Cassava is consumed in many tropical countries and is fast becoming the major raw material of many diets, especially in the bakery, brewery and pharmaceutical industries. In a study to determine the effects of various formulations of Cassava feeds on blood lipid profile in rats. Forty adult Wistar rats weighing between 120 and 150 g were divided into 4 groups of 10 rats each. The rats were acclimatized for one week; fed with different formulations of Cassava feeds adlibitum, after which the rats were allotted into groups. Group 1 was fed on Garri; group 2 on Cassava flour; group 3 on Tapioca, and the control group (group 4) on normal chow. After 4 weeks, each animal was anaesthetized by exposure to chloroform vapour and blood samples collected by cardiac puncture. Group 1 diet (Garri) significantly increased HDL-cholesterol (HDL-C) concentration and significantly decreased LDL-cholesterol (LDL-C) concentration (p<0.05) compared with the control group. In Group 2 (Cassava flour), t...

Ethnopharmacological Survey among Traditional Medicine Practitioners in Abidjan (Côte d'Ivoire) for the Management of Pathologies such as Malaria, ENT Diseases, Diarrhea, Typhoid Fever and Anemia | Chapter 05 | New Horizons in Medicine and Medical Research Vol. 8

 Traditional Medicine Practitioners (TMPs) of Côte d'Ivoire are familiar with the therapeutic herbs. Medicinal plants have been shown to be useful in the treatment of common diseases such as malaria (KROA, 2004) and diabetes (N'GUESSAN et al, 2013) in several studies and scientific study. In the Abidjan District, the current policy is to integrate traditional medicine and pharmacopoeia into the national health system in order to improve population health coverage, particularly in the management of commonly encountered diseases such as malaria, ENT diseases, diarrhoea, typhoid fever, and anaemia. This research aims to increase the use of traditional medicine and pharmacopoeia in the national health system. Over the course of three months, fifty (50) PMTs in the District of Abidjan participated in this study. Plant therapists accounted for 30 of the 50 PMTs polled at the end of the study, or 60%. Traditional medicine centres use 61 types of medicinal plants from 36 famili...
