In the past few decades, analysis of heart sound signals (i.e. the phonocardiogram or PCG), especially for automated heart sound segmentation and classification, has been widely studied and has been reported to have the potential value to detect pathology accurately in clinical applications. However, comparative analyses of algorithms in the literature have been hindered by the lack of high-quality, rigorously validated, and standardized open databases of heart sound recordings. This paper describes a public heart sound database, assembled for an international competition, the PhysioNet/Computing in Cardiology (CinC) Challenge 2016...

Obesity and heart failure are two of the leading causes of morbidity and mortality in the world. The relationship between obesity and cardiovascular diseases is complex and not fully understood. While the risk of developing heart failure has been shown to be higher in patients who are obese, there is a survival advantage for obese and overweight patients compared with normal weight or low weight patients. This phenomenon was first described by Horwich et al. and was subsequently confirmed in other large trials...

A 23-year-old asymptomatic woman was referred to our hospital for further examination of a systolic ejection murmur with fixed splitting of the second heart sound auscultated at the third left sternal border. Initial echocardiography could not detect the cause. Subsequently performed low-dose computed tomography, however, ruled out the possibility of any congenital heart diseases, but revealed a markedly shortened anteroposterior diameter of the chest, which led us to a diagnosis of straight back syndrome. A vertically oriented "pancake" appearance of the heart, straight vertebral column, and compression of the right ventricular outflow tract were clearly demonstrated on the reconstructed images...

This paper proposes the electronic heart sound sensor, based on the piezoresistive principle and MEMS (Micro-Electro-Mechanical System) technology. Firstly, according to the characteristics of heart sound detection, the double-beam-block microstructure has been proposed, and the theoretical analysis and finite element method (FEM) simulation have been carried out. Combined with the natural frequency response of the heart sound (20~600 Hz), its structure sizes have been determined. Secondly, the processing technology of the microstructure with the stress concentration grooves has been developed...

BACKGROUND: There is a global increase in rates of Cesarean delivery (CD). A minor factor in this increase is a shift towards CD for breech presentation. The aim of this study was to analyze breech births by mode of delivery and investigate short-term fetal and maternal outcomes in a low-income setting. METHODS: The study design was cross-sectional and the setting was Muhimbili National Hospital (MNH), Dar-es-Salaam, Tanzania. Subjects were drawn from a clinical database (1999-2010) using the following inclusion criteria: breech presentation, birth weight ≥ 2,500 g, single pregnancy, fetal heart sound at admission, and absence of pregnancy-related complication as indication for CD...

At the heart of prosthodontic treatment planning must be a sound understanding of the quality and reliability of the prosthodontic foundation. Implant prosthodontics relies almost entirely on the biological and mechanical properties of an osseous foundation. Initiation of therapy in the absence of a healthy and stable prosthodontic foundation risks unintended and suboptimal treatment outcomes. For conventional removable partial denture (RPD) therapy, consideration must be given to interactions between the soft and hard tissues available to support and stabilize planned prostheses...

BACKGROUND: Randomised controlled trials (RCTs) show that breastfeeding newborn infants during painful procedures reduces pain. Mechanisms are considered to be multifactorial and include sucking, skin-to-skin contact, warmth, rocking, sound and smell of the mother, and possibly endogenous opiates present in the breast milk. OBJECTIVES: To determine the effect of breastfeeding on procedural pain in infants beyond the neonatal period (first 28 days of life) up to one year of age compared to no intervention, placebo, parental holding, skin-to-skin contact, expressed breast milk, formula milk, bottle feeding, sweet-tasting solutions (e...

INTRODUCTION: Perioperative pain management is an integral part of anaesthesia and patients are most satisfied if there is minimal or no pain after surgery. Sciatic nerve block provides postoperative pain relief after below knee surgery and knee surgery. Many studies with different approaches for sciatic nerve block have been conducted to demonstrate the efficacy of sciatic nerve block with different local anaesthetic drugs over the past decade. AIM: To study the efficacy of single-shot sciatic nerve block for postoperative pain management in below knee orthopaedic surgery...

A new therapeutic agent for heart failure can be approved if it improves survival and/or reduces hospitalisations or if it safely improves functional capacity. Therefore its clinical development program must demonstrate clinically relevant improvement in a robust clinical end point and adequate safety to justify regulatory approval and clinical use. Mortality and hospitalisations are now combined with new composite end points in order to improve trial efficiency and adequate assessment of efficacy of newer molecules, biologicals and cell therapies developed for the treatment of heart failure...

Modified Early Warning Scores (MEWS) provide real-time vital sign (VS) trending and reduce ICU admissions in post-operative patients. These early warning calculations classically incorporate oxygen saturation, heart rate, respiratory rate, systolic blood pressure, and temperature but have not previously included end-tidal CO2 (EtCO2), more recently identified as an independent predictor of critical illness. These systems may be subject to failure when physiologic data is incorrectly measured, leading to false alarms and increased workload...

Cardiopulmonary exercise testing (CPET) is a specialized subtype of exercise testing that provides a more accurate and objective measure of cardiorespiratory fitness (CRF). CPET relies on measurement of ventilatory gases during exercise, i.e., a non-invasive procedure that involves the acquisition of expired ventilation and concentrations of oxygen (O2) and carbon dioxide (CO2) during progressive exercise. The non-invasive measurement of ventilation and expired gases permits the most accurate and reproducible quantification of CRF, a grading of the etiology and severity of impairment, and an objective assessment of the response to an intervention...

A young otherwise healthy 27-year-old male who has been using anabolic steroids for a long time developed Type I aortic dissection associated with heavy weightlifting. The patient did not have a recent history of trauma to the chest, no history of hypertension, and no illicit drug use. He presented with severe chest pain radiating to back and syncopal event with exertion. Initial vitals were significant for blood pressure of 80/50 mmHg, pulse of 80 beats per minute, respirations of 24 per minute, and oxygen saturation of 92% on room air...

From complex songs to simple honks, birds produce sounds using a unique vocal organ called the syrinx. Located close to the heart at the tracheobronchial junction, vocal folds or membranes attached to modified mineralized rings vibrate to produce sound. Syringeal components were not thought to commonly enter the fossil record, and the few reported fossilized parts of the syrinx are geologically young (from the Pleistocene and Holocene (approximately 2.5 million years ago to the present)). The only known older syrinx is an Eocene specimen that was not described or illustrated...

CONTEXT: Historical data has shown that cancer in general has been associated with less atherosclerosis while recently several studies have demonstrated more heterogeneous relations. However, most investigations were carried out clinically or radiographically and updated exhaustive, comprehensive autopsy studies are lacking. In our study, we aimed to assess the relationship between malignancy and grade of atherosclerosis in different locations (general, coronary) in a large study population over the course of 14 years...
