Deep Learning Digital Microscope Scanner Detects Malaria

Malaria remains a major global health problem with a need for improved field-usable diagnostic tests. Light microscopy assessment of blood smears to detect Plasmodium parasites remains the diagnostic gold standard and allows detection and quantification of Plasmodium species while also being more sensitive than rapid diagnostic tests (RDTs).

Specific Gut Bacterium Linked to Irritable Bowel Syndrome

The incidence of Irritable Bowel Syndrome (IBS) steeply increases following a gastroenteritis episode, suggesting a possible causative role for microbial perturbation. Gut microbiota composition studies overwhelmingly rely on fecal material. More...

Distinct Inflammatory Profiles Distinguish COVID-19 From Influenza

Acute respiratory failure occurs in a subset of COVID-19 patients. Understanding the etiology of respiratory failure in COVID-19 patients is critical for determining the best management strategies and pharmacologic targets for treatment. More...

SARS-CoV-2 RNA Test Assessed Among Recovered COVID-19 Patients

Some patients who have recovered from coronavirus disease 2019 (COVID-19) with documented negative real-time polymerase chain reaction (RT-PCR) results at the time of recovery have had subsequent positive RT-PCR test results for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). More...

Metagenomic Sequencing Quickly Identifies Pathogens in Body Fluids

Metagenomic next-generation sequencing (mNGS) is a shotgun sequencing approach in which all of the nucleic acid (DNA and RNA) in a clinical sample is sequenced at a very high depth, 10-20 million sequences per sample. More...

COVID-19 Lung Damage Caused by Persistence of Abnormal Cells

Several uncertainties still relate to the involvement of other organs in COVID-19. Besides indirect multi-organ injury, a few reports have suggested the possibility of direct injury caused by viral replication in brain, heart and kidney. More...

Rapid Tests Evaluated in the Management of Dengue Fever

Dengue is a mosquito-borne infection caused by four distinct viruses (DENV 1-4) which belong to the flavivirus genus and may lead to diverse outcomes. The disease can be asymptomatic in about 75% of cases, causing Dengue fever (DF), or result in severe dengue. Dengue is common in more than 120 countries. More...
