Heart rate characters

PURPOSE: To characterize intraplacental blood flow patterns in placenta accreta spectrum (PAS) with color and spectral Doppler imaging. METHODS: Thirty-two patients at risk for PAS underwent ultrasound imaging with both color and spectral Doppler. The placenta was inspected for areas of vascularity by color Doppler, particularly within the lower uterine segment. Spectral Doppler waveforms were obtained from these vessels and categorized as either intraplacental or subplacental (myometrial), venous or arterial, fetal or maternal (based on heart rate)...

Background: With the rapid improvement in economy and lifestyle, dietary risk-related diseases have become a public health problem worldwide. However, the health effects of dietary risk over time have not been fully clarified in China. Here, we explored the temporal trends in the death burden of unhealthy dietary habits in China and benchmark dietary risk challenges in China to G20 member states. Method: Sex-age-specific burdens due to dietary risk in China were extracted from the Global Burden of Disease (GBD) Study 2019, including annual numbers and age-standardized rates (ASRs) of death, disability-adjusted life years (DALYs), and summary exposure values (SEVs) during 1990-2019...

Loving-Kindness Meditation (LKM) is an efficient mental practice with a long history that has recently attracted interest in the fields of neuroscience, medicine and education. However, the neural characters and underlying mechanisms have not yet been fully illustrated, which has hindered its practical usefulness. This study aimed to investigate LKM from varied aspects and interactions between the brain, the heart, and psychological measurements. A Buddhist monk practitioner was recruited to complete one 10-min LKM practice, in between two 10-min resting tasks (pre- and post-resting) per experimental run...

We developed a novel interpretable biological heart age estimation model using cardiovascular magnetic resonance radiomics measures of ventricular shape and myocardial character. We included 29,996 UK Biobank participants without cardiovascular disease. Images were segmented using an automated analysis pipeline. We extracted 254 radiomics features from the left ventricle, right ventricle, and myocardium of each study. We then used Bayesian ridge regression with tenfold cross-validation to develop a heart age estimation model using the radiomics features as the model input and chronological age as the model output...

Heart failure is a common cardiovascular disease. The elderly have a high risk of illness. Many patients die of the disease every year. It has become a killer for all humans. Cardiovascular disease often triggers myocardial ischemia and myocardial cell apoptosis, resulting in myocardial damage and even heart failure in patients with cardiovascular disease. Related studies have shown that miRNA-19a/19b plays an important role in myocardial damage and heart failure character. The purpose of this article is to further explore the therapeutic effect of miRNA-19a/19b on heart failure and the regulation mechanism of myocardial regeneration and repair...

OBJECTIVE: It was intended to quantify cardiocirculatory stress and risk of professional football (soccer) coaches during competition. DESIGN: Descriptive cross-sectional study. SETTING: Medical screening examination and measurements during match. PARTICIPANTS: Seventeen coaches and 11 assistant coaches of the 2 highest German football leagues (male coaches; 46 ± 7 years; 8 ± 7 years in job). INDEPENDENT VARIABLES: Professional football matches with highly competitive character were chosen and monitored for elicited cardiocirculatory stress and possible damage...

According to the American College of Cardiology/American Heart Association (ACC/AHA), both aspirin and statin are used in the primary prevention of cardiovascular diseases. Aspirin (ASA) is contraindicated if there is gastrointestinal bleeding because it will exaggerate the condition. In this study, the effect of surfactant; sodium lauryl sulfate (SLS), in enhancing the in vitro dissolution of simvastatin (SIM) and ASA, as well as gastric irritation and upset, was studied. Oral tablets containing both ASA and SIM with and without the SLS were manufactured using the direct compression technique...

Oriented lines impact human cognition subconsciously. This study aimed to determine whether line orientations in the background of Chinese written characters influenced individual's memory and emotion. Five pictures with Chinese characters as experimental material, in which four had equidistant parallel lines (0°, -45°, 90°, and +45°) as background and the other one had a blank background, were presented on a personal computer screen, for 15 seconds each, to 94 participants. The participants were then given 45 seconds to write down what they had just memorized...

BACKGROUND: Adolescents in low- and middle-income countries in need of mental health care often do not receive it due to stigma, cost, and lack of mental health professionals. Culturally appropriate, brief, and low-cost interventions delivered by lay-providers can help overcome these barriers and appear effective at reducing symptoms of depression and anxiety until several months post-intervention. However, little is known about whether these interventions may have long-term effects on health, mental health, social, or academic outcomes...

BACKGROUND: Repeated or chronic stress is considered a major source of disease, in terms of both somatic and mental illnesses. The prevention of stress-related disease by interventions for relaxation has thus increased societal relevance. In this randomized controlled non-inferiority trial, we will compare a newly developed virtual reality (VR) environment for relaxation to an active control group applying a freely chosen relaxation method. To test if our VR environment supports relaxation in a situation of acute stress, a standardized stress induction protocol will precede the relaxation phase...

Distinguishing among similar events is indeed crucial to memory. In a dangerous context, this ability may be less essential, whereas in a secure context it may provide an adaptative advantage notably in social situations. Vagal activity as a marker of the individual's adaptation in social engagement contexts might predict the ability to discriminate highly similar memories in an unthreatening context. The present study aims to test the relation between vagal activity and memory discrimination by manipulating the visual distinctiveness of stimuli (high vs...

Activity in both divisions of the autonomic nervous system (ANS) can increase during seizures and result in tachy- or bradyarrhythmias. We sought to determine the patterns of ANS activity that led to heart rate (HR) changes and whether the character of ANS and HR changes can impact the seizures themselves. Simultaneous recordings of vagus nerve and cervical sympathetic ganglionic or nerve activity, EEG, ECG, and blood pressure were acquired from 16 urethane-anesthetized rats that received systemic kainic acid to induce seizures...

Alice in Wonderland syndrome (AIWS) is a rarely curious visual perceptual disorder which has been associated with diverse neurologic and psychiatric problems. It may be a manifestation in migraine, epileptic seizures, encephalitis, other brain lesions, medication-related side effects, schizophrenia, and depressive disorders. Principal character of AIWS is the disproportion between the external world and the self-image in which micropsia (objects appear smaller), macropsia (objects appear larger), and teleopsia (objects appear further away) are frequently reported...

OBJECTIVE: Patients with multi-vessel coronary artery disease (MVD) compared to single-vessel coronary artery disease (CAD) have more comorbidities and poor in-hospital outcomes. We aim to analyze MVD-AMI patients regarding clinical data and short-term outcomes. METHODS: This is a retrospective analysis of the prospectively collected data registry, a single-center study reviewing the clinical details and hospital outcome measures of AMI patients referred to our center for early revascularization from 2016 to 2019...

Along other breakthroughs in computer sciences, such as artificial intelligence, virtual characters (i.e. digitally represented characters featuring a human appearance or not) are foreseen as potential providers of mental healthcare services. However, their current use in clinical practice is marginal and limited to an assistive role to help clinicians in their practices. Safety and efficiency concerns, as well as a general lack of knowledge and experience, may explain this discrepancy between the expected (sometimes futuristic) and current use of virtual characters...

OBJECTIVES: This study aimed to compare the effectiveness of paced breathing (PB) versus su-soku practice (spontaneous breathing with counting numbers) on autonomic function and brain activity and examine the associations between personality traits, brain activity, and autonomic function. DESIGN: A three-way crossover study design. SETTING: Thirty healthy Korean participants (15 men: 28.5 ± 4.7 years; 15 women: 27.7 ± 4.8 years) were asked to answer the Korean version of the 125-Temperament and Character Inventory (TCI)...

Routine blood pressure (BP) measurement in pregnancy is commonly performed using automated oscillometric devices. Since no wireless oscillometric BP device has been validated in preeclamptic populations, a simple approach for capturing readings from such devices is needed, especially in low-resource settings where transmission of BP data from the field to central locations is an important mechanism for triage. To this end, a total of 8192 BP readings were captured from the Liquid Crystal Display (LCD) screen of a standard Omron M7 self-inflating BP cuff using a cellphone camera...

In 2019, a new virus, SARS-CoV-2, responsible for the COVID-19 disease, was discovered. Asymptomatic and mildly symptomatic patients were forced to quarantine and closely monitor their symptoms and vital signs, most of the time at home. This paper describes e-CoVig, a novel mHealth application, developed as an alternative to the current monitoring paradigm, where the patients are followed up by direct phone contact. The e-CoVig provides a set of functionalities for remote reporting of symptoms, vital signs, and other clinical information to the health services taking care of these patients...

RATIONALE: First discovered in 1990, the endocannabinoid system (ECS) was initially shown to have an intimate relationship with central areas of the nervous system associated with pain, reward, and motivation. Recently, however, the ECS has been extensively implicated in the cardiovascular system with contractility, heart rate, blood pressure, and vasodilation. Emerging data demonstrate modulation of the ECS plays an essential role in cardio metabolic risk, atherosclerosis, and can even limit damage to cardiomyocytes during ischemic events...

Heart Rate Variability (HRV) has been suggested as a useful tool to assess fatigue-sensitive psychological operations. The present study uses a between and within-subject design with a cognitively demanding task and a documentary viewing condition, to examine the temporal profile of HRV during reactivity, Time-on-Task (ToT), and recovery. In the cognitive task group, participants worked on a bimodal 2-back task with a game-like character (the Gatekeeper task) for about 1.5 hours, followed by a 12-minute break, and a post-break block of performance (about 18 min)...
