Cardiac auscultation is one of the most cost-effective techniques used to detect and identify many heart conditions. Computer-assisted decision systems based on can support physicians in their decisions. Unfortunately, application such clinical trials still minimal since them only aim presence extra or abnormal waves phonocardiogram signal, i.e., a binary ground truth variable (normal vs abnormal) provided. This mainly due lack large publicly available datasets, where more detailed...
Abstract Cardiac auscultation is an accessible diagnostic screening tool that can help to identify patients with heart murmurs for follow-up and treatment abnormal cardiac function. However, experts are needed interpret the sounds, limiting accessibility of care in resource-constrained environments. Therefore, George B. Moody PhysioNet Challenge 2022 invited teams develop algorithmic approaches detecting function from phonocardiogram (PCG) recordings sounds. For Challenge, we sourced 5272...
HipertensãoOs estudos epidemiológicos sobre hipertensão (HAS) primária na infância e adolescência realizados no Brasil demonstraram uma prevalência que variou de 0,8% a 8,2% 1,2 .A exemplo do foi observado em adultos, muitos desses trabalhos freqüente associação HAS com sobrepeso ou obesidade. Sobrepeso obesidadeNos últimos 30 anos, um rápido declínio da desnutrição crianças adolescentes elevação, num ritmo mais acelerado, sobrepeso/obesidade adultos.A análise dos dados 2 17 Pesquisa Padrão...
To determine the frequence and profile of congenital heart defects in Down syndrome patients referred to a pediatric cardiologic center, considering age referral, gender, type disease diagnosed by transthoracic echocardiography its association with pulmonary hypertension at initial diagnosis.Cross-sectional study retrospective data collection 138 from total 17,873 records. Descriptive analysis was performed, using Epi-Info version 7.Among syndrome, females prevailed (56.1%) 112 (81.2%) were...
To assess the number of children born with microcephaly in State Paraíba, north-east Brazil.We contacted 21 maternity centres belonging to a paediatric cardiology network, access information regarding more than 100 000 neonates between 1 January 2012 and 31 December 2015. For 10% these neonates, nurses were requested retrieve head circumference measurements data from delivery-room books. We used three separate criteria classify whether neonate had microcephaly: (i) Brazilian Ministry Health...
Abstract The recent outbreak of Zika virus (ZIKV) disease caused an enormous number infections in Central and South America, the unusual increase infants born with microcephaly associated ZIKV infection aroused global concern. Here, we developed a reverse transcription loop-mediated isothermal amplification (RT-LAMP) assay using portable device for detection ZIKV. specifically detected strains both Asian African genotypes without cross-reactivity other arboviruses, including Dengue...
Auscultation is widely applied in clinical activity, nonetheless sound interpretation dependent on clinician training and experience. Heart features such as spatial loudness, relative amplitude, murmurs, localization of each component may be indicative pathology. In this study we propose a segmentation algorithm to extract heart components (S1 S2) based it's time frequency characteristics. This takes advantage the knowledge cycle times (systolic diastolic periods) spectral characteristics...
The Tracking Outcomes and Practice in Pediatric Pulmonary Hypertension (TOPP) registry is a global network established to gain insights into the disease course long-term outcomes of paediatric pulmonary arterial hypertension (PAH). Previously published cohorts PAH are obscured by survival bias due inclusion both prevalent (previously diagnosed) incident (newly patients. current study aims describe outcome its predictors PAH, exclusively newly diagnosed
Abstract The Eighth World Congress of Pediatric Cardiology and Cardiac Surgery (WCPCCS) will be held in Washington DC, USA, from Saturday, 26 August, 2023 to Friday, 1 September, 2023, inclusive. the largest most comprehensive scientific meeting dedicated paediatric congenital cardiac care ever held. At time writing this manuscript, has 5,037 registered attendees (and rising) 117 countries, a truly diverse international faculty over 925 individuals 89 2,000 individual abstracts poster...
Providing health care for children with congenital heart diseases remains a major challenge in low- and middle-income countries.In October 2011, the Government of Paraíba, Brazil, established paediatric cardiology network partnership nongovernmental organization Círculo do Coração. A team supervised all activities, using Internet to keep contact remote facilities. The developed protocols screening defects. Echocardiograms were performed by physicians under direct online supervision...
Early detection of congenital heart disease is a worldwide problem. This more critical in developing countries, where shortage professional specialists and structural health care problems are constant. E-learning has the potential to improve capacity, by overcoming distance barriers its ability adapt reduced time professionals.The study aimed develop an e-learning pediatric cardiology basics course evaluate pedagogical impact user satisfaction.The sample consisted 62 professionals, including...
Rheumatic heart disease remains a major burden in the developing countries. The World Heart Federation proposed guidelines for echocardiographic detection of disease, which mitral leaflets' morphology assessment is key indicator. drawback that these are dependent on clinician experience. To overcome this limitation, we propose an automatic segmentation leaflets using new method based convolutional neural network, specifically UNet architecture. results indicate median DICE coefficient 0.74...
Digital stethoscopes are medical devices that can collect, store and sometimes transmit acoustic auscultation signals in a digital format. These then be replayed, sent to colleague for second opinion, studied detail after an auscultation, used training or, as we envision it, cheap powerful tool screening cardiac pathologies. In this work, present the design, development deployment of prototype collecting annotating within real hospital environments. Our main objective is not only pave way...
The blood pressure to height ratio (BP:HT) has been proposed as a simple method for identifying children with elevated BP. This procedure shows good accuracy the screening of hypertension in adolescents but less so younger children. Our aim this study was modify BP:HT and determine if change would increase when measuring during childhood.BP levels 4,327 (aged 5-12 years) were retrospectively obtained from medical charts. modified (BT:eHT13) calculated as: BP/(HT + 7 × (13 - age years))....
Objective: To determine if in-hospital mortality after cardiac surgery can be predicted, in children, using a new clinical and surgical index. Study design: Observational, retrospective, cross-sectional. Methods: We reviewed 818 charts from children undergoing between January, 2000, December, 2004. The index was calculated by summing the scores five variables, specifically age, nutritional state, presence of associated risk factors, complexity, use time cardiopulmonary bypass. Each variable...
The George B. Moody PhysioNet Challenge 2022 explored the detection of abnormal heart function from phonocardiogram (PCG) recordings.Although ultrasound imaging is becoming more common for investigating defects, PCG still has potential to assist with rapid and low-cost screening, automated annotation recordings further improve access.Therefore, this Challenge, we asked participants design working, opensource algorithms that use identify murmurs clinical outcomes.This makes several...
We propose a denoising and segmentation technique for the second heart sound (S2). To denoise, Matching Pursuit (MP) was applied using set of non-linear chirp signals as atoms. show that proposed method can be used to segment phonocardiogram into its two clinically meaningful components: aortic (A2) pulmonary (P2) components.
