Abstract

To determine the factors contributing to the use of over-the-counter (OTC) drugs and to examine the relationship between the purchase of OTC drugs and the utilization of health care services in South Korea. This study used data from the 2008 Korea Health Panel Survey. The respondents were classified according to the purpose of the OTC drug use. The first group (n = 364) included respondents who had purchased OTC drugs for self-medication, and the second group (n = 955) included respondents who had taken OTC drugs for nutrition for more than 3 months. Logistic regression analyses were conducted to identify the factors contributing to the purchase of OTC drugs. The self-medication group was more likely to be older and to have a chronic disease. In addition, the purchase of OTC drugs was related to the utilization of other health care services. The more outpatient services at clinics were used, the more the respondents tended to purchase OTC drugs for self-medication and nutrition. As hospital outpatient visits increased, however, the purchase of OTC drugs for self-medication decreased and the purchase of OTC drugs for nutrition increased. This study shows that age and chronic disease are the major factors related to using OTC dru...Continue Reading

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.

Bone Marrow Neoplasms

Bone Marrow Neoplasms are cancers that occur in the bone marrow. Discover the latest research on Bone Marrow Neoplasms here.

IGA Glomerulonephritis

IgA glomerulonephritis is a chronic form of glomerulonephritis characterized by deposits of predominantly Iimmunoglobin A in the mesangial area. Discover the latest research on IgA glomerulonephritis here.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

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.

LRRK2 & Immunity During Infection

Mutations in the LRRK2 gene are a risk-factor for developing Parkinson’s disease. However, LRRK2 has been shown to function as a central regulator of vesicular trafficking, infection, immunity, and inflammation. Here is the latest research on the role of this kinase on immunity during infection.

Antiphospholipid Syndrome

Antiphospholipid syndrome or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by the presence of antibodies directed against phospholipids.

Meningococcal Myelitis

Meningococcal myelitis is characterized by inflammation and myelin damage to the meninges and spinal cord. Discover the latest research on meningococcal myelitis here.

Alzheimer's Disease: MS4A

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