Abstract

Eight hundred and fifty-four patients of 928 who had attended a mass radiographic tuberculosis survey and in whom the diagnosis of non-tuberculous lung disease had been made, were located two years after the survey. This was the second follow-up survey of this group, the first having been at four months. The majority of patients were well, but 247 were ill and 101 had died. Serious non-tuberculous chest disease can be diagnosed with accuracy at mass surveys but the benefit to the patient of having these conditions detected is less clear. Serious progressive conditions that lead to death or ill health within two years appear to become symptomatic and force the sufferer to seek medical advice at about the same time that they are detected at mass surveys. This fact, coupled with the low yield of previously unknown tuberculosis, makes the future use of general mass radiographic surveys questionable in areas with good medical services. Evidence is presented that suggests screening directed to specific age groups may be more productive.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Alzheimer's Disease: MS4A

Variants within the membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease in genome-wide association studies. Here is the latest research on Alzheimer's disease and MS4A.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Laryngeal Neoplasms

Laryngeal Neoplasms occur in the Larynx and are typically associated with smoking and alcohol consumption. Discover the latest research on Laryngeal Neoplasms here.

Cell Atlas Along the Gut-Brain Axis

Profiling cells along the gut-brain axis at the single cell level will provide unique information for each cell type, a three-dimensional map of how cell types work together to form tissues, and insights into how changes in the map underlie health and disease of the GI system and its crosstalk with the brain. Disocver the latest research on single cell analysis of the gut-brain axis here.
