Machine learning is a branch of artificial intelligence that helps machines learn from observational data without being explicitly programmed and its methods have been found to be very useful in the modern age for medical diagnosis and for early detection of diseases. According to the World Health Organization, 12 million deaths occur annually due to heart-related diseases. Thus, its early detection and treatment are of interest. This research introduces a better way of improving the timely prediction of cardiovascular diseases in suspected patients by comparing the efficiency of two boosting algorithms with four (4) other single based classifiers on cardiovascular official data. The best model was selected based on performances of 5 different evaluation metrics. From the results, Adaptive boosting is seen to outperform all other algorithms with a classification accuracy of 74.2%, closely followed by gradient boosting. However, gradient boosting was chosen as an acceptable technique because it trains faster than Adaboost with a better precision of 74.9% compared to 74.7% exhibited by Adaboost. Thus boosting algorithms are better predictors compared to single based classifiers with factors of age, systolic blood pressure, weight, cholesterol, height, and diastolic blood pressure as the major contributors to the model building.

Salt consumption is now much greater than needed for survival. High salt intake increases blood pressure in both animals and humans. Conversely, a reduction in salt intake causes a dose-dependent reduction in blood pressure in men and women of all ages and ethnic groups, and in patients already on medication. The risk of strokes and heart attacks rises with increasing blood pressure, but can be decreased by antihypertensive drugs. However, most cardiovascular disease events occur in individuals with ‘normal’ blood pressure levels. Non-pharmacological prevention is therefore the only option to reduce such events. Reduction in population salt intake reduces the number of vascular events. It is one of the most important public health measures to reduce the global cardiovascular burden. Salt reduction policies are powerful, rapid, equitable, and cost saving. The World Health Organization recommends reducing salt consumption below 5 g per day aiming at a global 30% reduction by 2025. A high potassium intake lowers blood pressure in people with and without hypertension. Its beneficial effects extend beyond blood pressure, and may include a reduction in the risk of stroke (independent of blood pressure changes). Potassium intake in the Western world is relatively low, and a lower potassium intake is associated with increased risks of cardiovascular disease, especially stroke. A moderate increase in potassium intake, either as supplement or with diet, reduces blood pressure, and the World Health Organization has issued global recommendations for a target dietary potassium intake of at least 90 mmol/day (≥3510 mg/day) for adults.

Objective: The principal aim of the study is to identify the effect of physical exercise and yoga on blood pressure (BP) among children, a common cardiovascular risk factor among children in recent years. Methods: A true experimental design was adopted to find the effect of physical exercise and yoga on selected children with increased BP and weight. The weight was inferred based on the World Health Organization (WHO) chart on body mass index for age. BP and height were measured and interpreted using the WHO height percentile chart for boys/girls and BP references of National Heart, Lung, and Blood Institute, to identify hypertensive children. Hypertensive children were given physical exercise and yoga, 5 days a week, for 6 months and control group led a normal lives. Results: In the pretest, 100% of the study and control group were prehypertensive. After 3 months of physical exercise and yoga, 21% of study group became normotensive which was significant at p=0.000 and it increased to 93% after 6 months with the significance of p=0.000. The weight and systolic BP (SBP) had a significant positive correlation. The age (p=0.001), number of family members, type of family (p=0.01), mother’s occupation, family history of obesity, and chronic illness among fathers (p=0.05) had a significant association with SBP of the children. Conclusion: The study concluded that physical exercise and yoga reduced childhood hypertension as well as is a cost effective and easily practicable intervention for children to minimize cardiovascular risk during their adulthood.

Abstract Different countries have adopted strategies for the early detection of SARS-CoV-2 since the declaration of community transmission by the World Health Organization (WHO) and timely diagnosis has been considered one of the major obstacles for surveillance and healthcare. Here, we report the increase of the number of laboratories to COVID-19 diagnosis in Brazil. Our results demonstrate an increase and decentralisation of certified laboratories, which does not match the much higher increase in the number of COVID-19 cases. Also, it becomes clear that laboratories are irregularly distributed over the country, with a concentration in the most developed state, São Paulo.

The World Health Organization identifies hypertension (AH) as «the world’s leading global risk of increased mortality from cardiovascular disease». AH is one of the most serious health problems because of its prevalence and importance. Caring for a patient with AH with or without chronic comorbidity requires a long-term holistic, patient-centered approach. The goal of treating a patient with AH is to reduce the overall cardiovascular risk, notu jst to control blood pressure. The aim is to analyze the possibilities of basic drug therapy and control over its implementation in patients with hypertension in different clinical situations in the practice of a family physician. Newly detected AH in a patient requires careful examination and appointment of effective comprehensive treatment. The tactics of selection of antihypertensive treatment for a patient with newly diagnosed hypertension are considered on a clinical example. Improving lifestyle and healthy living habits are necessary for all patients with AH, even when antihypertensive medication is mandatory. It is important to regulate blood pressure. The choice of medication depends on the patient’s characteristics and comorbidities. Care of a patient with hypertension should be carried out holistically with the identification and control of additional risk factors and complications, in parallel with the control of hypertension. At the same time it is necessary to take care of the treatment of some other somatic diseases or mental disorders that may affect the outcome of treatment of hypertension.

Introduction: Body mass index is an important parameter associated with a variety of disease processes. The risk of hypertension and cardiovascular diseases increases with an increase in body mass index. The study was conducted to compare the relationship between body mass index and blood pressure. Objective: To evaluate the prevalence and correlate the Obesity and Hypertension in    medical students  Methodology: The study was conducted in 200 students (113 males and 87 females). Height, weight and blood pressure were recorded from all participants and body mass index was calculated. The recorded body mass index was utilized to divide the student into underweight, normal, over weight and obese category according to the World Health organization body mass index classification. Hypertension was determined from the measure of blood pressure. Then comparison of blood pressure with body mass index was made. Results: Among 200 students 6% were obese, 22% were overweight, 65% were normal and 7% underweight. The mean height was 163cm and mean weight 60.48kg. The mean value of systolic blood pressure (105.85, 115.45, 134.95, 137.16 mmHg) and diastolic blood pressure (70.14, 76.15, 90.72, 93.33 mmHg) increased with increasing body mass index. Conclusion: Overweight and obesity increases the risk of hypertension among students.
