Commercial RT-PCR Tests Compared to Culture for Bacterial Gastroenteritis

Nucleic acid-based testing (culture-independent diagnostic testing, CIDT) for bacterial gastroenteritis offers three major advantages over culture-based diagnosis: it has better analytical sensitivity, is less labor intensive through automation, and has faster turnaround times. More...

Skin Infections Confirmed as a Cause of Acute Rheumatic Fever

Infection with group A streptococcus (GAS) can trigger an immune-mediated response in a small minority of people, resulting in acute rheumatic fever (ARF). ARF produces an inequitable burden of disease, with the highest rates in low and middle-income countries and among some, often indigenous-minority populations living in high-income countries. More...

Menstrual Blood Testing With Capture Sequencing Detects High-Risk Human Papillomavirus

Persistent infection of high-risk human papillomavirus (hrHPV) is associated with various HPV-related pre-cancers and cancers. In recent years, HPV testing has gradually become the primary method for cervical cancer screening. More...

Parkinson’s Disease Patients Have More Inflammatory Bacteria in Their Noses

Parkinson’s disease (PD) is a complex neurodegenerative disease characterized by nigrostriatal degeneration resulting in bradykinesia, rigidity, tremor, and gait dysfunction. Non-motor symptoms are also typically present, including depression, constipation, and alteration of smell. Diminished sense of smell (hyposmia), is a common hallmark of prodromal PD. More...

Calprotectin Levels Vary When Measured in Different Matrices for COVID-19

Several risk scores, diagnostic imaging and biomarkers have been evaluated and compared to help predict severe complications and outcome in COVID-19 patients. Nevertheless, early prediction of COVID-19 severity remains difficult, emphasizing the need for additional biomarkers in daily practice. More...

Bacterial Communities Diverge in The Lower Airways of CF Children

Chronic airway infection and inflammation resulting in progressive, obstructive lung disease is the leading cause of morbidity and mortality in people with cystic fibrosis (CF). Culture-independent, molecular approaches have broadened the view from a few individual pathogens to more complex and dynamic polymicrobial communities. More...
