Blood pressure (BP) measurement is a major physiological information for people with cardiovascular diseases, such as hypertension, heart failure, and atherosclerosis. Moreover, elders and patients with kidney disease and diabetes mellitus also are suggested to measure their BP every day. The cuffless BP measurement has been developed in the past 10 years, which is comfortable to users. Now, ballistocardiogram (BCG) and impedance plethysmogram (IPG) could be used to perform the cuffless BP measurement. Thus, the aim of this study is to realize edge computing for the BP measurement in real time, which includes measurements of BCG and IPG signals, digital signal process, feature extraction, and BP estimation by machine learning algorithm. This system measured BCG and IPG signals from a bodily weight-fat scale with the self-made circuits. The signals were filtered to reduce the noise and segmented by 2 s. Then, we proposed a flowchart to extract the parameter, pulse transit time (PTT), within each segment. The feature included two calibration-based parameters and one calibration-free parameter was used to estimate BP with XGBoost. In order to realize the system in STM32F756ZG NUCLEO development board, we limited the hyperparameters of XGBoost model, including maximum depth (max_depth) and tree number (n_estimators). Results show that the error of systolic blood pressure (SBP) and diastolic blood pressure (DBP) in server-based computing are 2.64 ± 9.71 mmHg and 1.52 ± 6.32 mmHg, and in edge computing are 2.2 ± 10.9 mmHg and 1.87 ± 6.79 mmHg. This proposed method significantly enhances the feasibility of bodily weight-fat scale in the BP measurement for effective utilization in mobile health applications.

Background: Metabolic syndrome (MetS) is an important public health issue that has been lately linked as a growing concern worldwide.
The Objective: To find out which anthropometric and body composition indices can prognosticate MetS in Jordanian adult females.
Methods: A sample of 656 Jordanian adult females was recruited (January-March 2024) in the middle of Jordan.

Background: Non-adherence to antihypertensive medication is a key factor contributing to uncontrolled blood pressure and the subsequent complications of hypertension. Despite its importance, there is a lack of data regarding the prevalence of and factors associated with non-adherence to medication among individuals with hypertension in India. This review aimed to assess medication adherence rates among hypertensive patients in India and identify the factors influencing non-adherence.

A 61-year-old man with chronic renal failure had an embolic stroke of undetermined source that was treated with warfarin. Five weeks later, the patient contracted coronavirus disease (COVID-19). Six days after the onset of COVID-19, high blood pressure (>200 mmHg) and consciousness disturbance were reported.

Disease screening aims to identify individuals at risk for specific conditions. It is expected that an early detection allows for early intervention, with improved outcomes. However, large scale screening programs may not only have implications on resources, patient outcomes may not improve but may worsen if screening for the targeted disease has not been carefully designed and executed.
