Background: Trypanosoma cruzi causes Chagas disease in the Americas. Outcome of infection ranges from lifelong asymptomatic status to severe disease. Understanding how history of T. cruzi lineage (TcI-TcVI) infection relates to clinical prognosis is challenging. We previously described peptide-based lineage-specific ELISA with Trypomastigote Small Surface Antigen (TSSA). Methods: A novel rapid diagnostic test (Chagas Sero K-SeT) incorporating a peptide corresponding to the TSSA-II/V/VI common epitope was developed, and validated by comparison with ELISA...

Cardiac output (CO) and stroke volume (SV) are parameters of key clinical interest. Many techniques exist to measure CO and SV, but are either invasive or insufficiently accurate in clinical settings. Electrical impedance tomography (EIT) has been suggested as a noninvasive measure of SV, but inconsistent results have been reported. Our goal is to determine the accuracy and reliability of EIT-based SV measurements, and whether advanced image reconstruction approaches can help to improve the estimates. Data were collected on ten healthy volunteers undergoing postural changes and exercise...

BACKGROUND: QRS fragmentation (fQRS) is believed to reflect myocardial scar formation in patients with coronary disease. Whether early formation of fQRS in patients with ST-segment elevation myocardial infarction (STEMI) treated with percutaneous coronary intervention (PCI) is correlated with infarct size and prognosis is unknown. We assessed the prognostic value of fQRS at 60min post-PCI and its correlation with infarct size in patients with anterior STEMI managed with primary PCI. METHODS: The INFUSE-AMI trial enrolled 452 patients with anterior STEMI undergoing primary PCI...

BACKGROUND: KAF156 is a novel imidazolopiperazine anti-malarial with activity against pre-erythrocytic liver stages, asexual and sexual blood stages. Based on in vitro data, a two-way pharmacokinetic interaction was hypothesized for KAF156 use in combination with piperaquine (PPQ) as both drugs are CYP3A4 substrates and inhibitors. Potential combination effects on the QT interval were also assessed. METHODS: This was an open-label, parallel-group, single-dose study in healthy volunteers randomized to three parallel arms (1:1:1) of 800 mg KAF156 + 1280 mg PPQ, 800 mg KAF156 alone and 1280 mg PPQ alone...

OBJECTIVES: Co-morbidities affect survival after in-hospital cardiac arrests (IHCA). The risk population for IHCA, i.e. the hospitalised patients, have a doubled increase in co-morbidities over time. A similar increase in co-morbidities among IHCAs might explain the relatively poor survival ratios despite improved care. AIM: To assess changes in the burden of baseline age-adjusted Charlson co-morbidity index (ACCI) scores among IHCAs as well as to assess its impact on survival in three time periods...

Aging affects baroreflex regulation. The effect of senescence on baroreflex control was assessed from spontaneous fluctuations of heart period (HP) and systolic arterial pressure (SAP) through the HP-SAP gain, while the HP-SAP phase and strength are usually disregarded. This study checks whether the HP-SAP phase and strength, as estimated respectively via the phase of the HP-SAP cross-spectrum (PhHP-SAP) and squared coherence function (K2HP-SAP), varies with age in healthy individuals and trends are gender-dependent...

We sought to characterize presenting electrocardiographic findings in patients with acute coronary syndromes (ACSs) and out-of-hospital cardiac arrest (OHCA). In the Global Registry of Acute Coronary Events and Canadian ACS Registry I, we examined presenting and 24- to 48-hour follow-up ECGs (electrocardiogram) of ACS patients who survived to hospital admission, stratified by presentation with OHCA. We assessed the prevalence of ST-segment deviation and bundle branch blocks (assessed by an independent ECG core laboratory) and their association with in-hospital and 6-month mortality among those with OHCA...

BACKGROUND: Trends in the use of antithrombotic drugs in elderly patients with atrial fibrillation (AF) are largely unknown. We estimated the prevalence of AF in an older population, and examined whether use of anticoagulant and antiplatelet drugs in older AF patients has changed over time. METHODS: Data from the population-based Swedish National study on Aging and Care in Kungsholmen (n=3363, age≥60years, 64.9% women) were used (2001-2004 and 2007-2010). AF cases were identified through 12-lead electrocardiogram, physician examinations, and patient register records (ICD-10 code I48)...

Photoplethysmography(PPG) as a non-invasive tool for monitoring various cardiovascular parameters, has become popular due to the ease of wearable integration and pervasive nature. Due to unobtrusive nature of sensor placement at wrist, smartwatches and wrist based fitness bands have gained popularity. However, any movement of the wrist along with frequent loose contacts significantly corrupts the PPG signal. Reliable peak detection from the corrupted PPG signal is essential for any further processing, as many physiological quantities such as heart rate variability (HRV) depends on the peak-to-peak distances in the PPG signal, known as the RR Series...
