BACKGROUND Rheumatic heart disease (RHD) remains a major public health concern in developing countries, and routine screening has the potential to improve outcomes. Standard portable echocardiography (STAND) is far more sensitive than auscultation for the detection of RHD but remains cost-prohibitive in resource-limited settings. Handheld echocardiography (HAND) is a lower-cost alternative. The...
Some of the highest recorded rheumatic heart disease (RHD) prevalence and mortality rates are from the World Health Organization's Western Pacific Region (WPR). RHD burden has been well documented in much of the WPR subregion of Oceania, but less is known about RHD outside the Pacific Islands and Australasia. We aimed to review RHD burden in WPR outside Oceania to identify countries with high R...
BACKGROUND Although acute rheumatic fever (ARF) and its sequel, rheumatic heart disease (RHD), continue to cause a large burden of morbidity and mortality in disadvantaged populations, most studies investigating the effectiveness of control programs date from the 1950s. A control program, including a disease register, in the Northern Territory of Australia where the Indigenous population has hi...
BACKGROUND The objective of this study was to compare the expression of heat shock proteins (HSPs) between rheumatic heart disease (RHD) patients with atrial fibrillation (AF) and RHD patients without AF, and its efficacy in predicting the occurrence of AF in RHD patients. METHODS Ninety-five patients were enrolled in our study, including 60 RHD patients with AF, and 35 RHD patients without A...
A two-locus gene conversion model with selection is developed. Under the joint action of selection, mutation, gene conversion, recombination, and random genetic drift, approximate formulas for the expectations of the moments of allele frequencies and the expected amounts of variation within and between two loci are obtained by a diffusion method assuming relatively strong selection. It is shown...
Rh blood group antigens of the D, C/c, and E/e series are carried by at least three red cell membrane polypeptides encoded by two highly related genes, RHD and RHCE. Homozygous individuals carrying the D--, Dc-, and DCw- gene complexes are characterized by a total or partial lack of expression of the RHCE-encoded antigens. Analysis of the molecular genetic basis of these rare conditions indicat...
In the Rh blood system, RhAG (Rhassociated glycoprotein, or Rh50) is thought to be involved in Rh30 (D, CE) expression by forming a protein complex on the red cell surface. To obtain further insight into the Rh complex, we chose nonerythroid COS-1 cells instead of proerythroblast-like K562 cells, which produce endogenous Rh proteins as cell host, for the expression of both RhAG and RhD. The RhA...
OBJECTIVE To estimate the accuracy of a new assay to determine the fetal RHD status using circulating cell-free DNA. METHODS This was a prospective, observational study. Maternal blood samples were collected in each trimester of pregnancy in 520 nonalloimmunized RhD-negative patients. Plasma samples were analyzed for circulating cell-free DNA using the SensiGENE RHD test, which used primers f...
BACKGROUND Echocardiographic screening for rheumatic heart disease (RHD) is becoming more widespread, but screening studies to date have used different echocardiographic definitions. The World Heart Federation has recently published new criteria for the echocardiographic diagnosis of RHD. We aimed to establish the prevalence of RHD in high-risk Indigenous Australian children using these criteri...
