Gram staining of expectorated sputum is a simplistic, easy-to-perform, commonly available, and low-cost diagnostic for pneumonia patients. Sputum Gram stain may detect many infections at the same time, and the test has a quick turnaround time. With adequate specimens, the sputum Gram stain can aid in establishing the right bacterial …
Lactic acidosis is caused by high levels of lactic acid (lactate) and protons in the bodily secretions and is usually associated with poor clinical outcomes. The intensity and clinical setting of lactic acidosis influence its impact. Lactic acid, a carbohydrate metabolism intermediate, is mostly produced by white skeletal muscle, the …
Thalassemia is a spectrum of genetic conditions in which one or more globin genes are defective, resulting in reduced or deficient synthesis of the related globin chains. Patients with minor genetic abnormalities are usually asymptomatic. Patients with more severe abnormalities have symptoms caused by one or more of the following: …
A blood clot arises as a result of any injury to the body tissues. Blood clots, on the other hand, can trigger severe complications like strokes or MI in heart related dysfunction. Anticoagulants such as aspirin or warfarin are often administered for life as prophylaxis. These medications reduce clot formation …
Trimethylamine N-oxide (TMAO) is a metabolite derived from dietary nutrients processed by gut bacteria. Emerging research links high TMAO levels to an increased risk of cardiovascular diseases, including heart attacks and strokes. It is essential to understand TMAO production, its impact on cholesterol metabolism, and its broader health implications for …
Atherosclerosis, also known as coronary artery disease (CAD), is the most common form of cardiovascular disease (CVD) and a leading cause of death worldwide. This condition is characterized by the buildup of lipids (fats) and inflammation in the large arteries. Over time, this accumulation can lead to severe complications like …
Rotavirus is a widely recognised cause of acute gastroenteritis in young children all around the world. Almost every child under the age of five is at risk of contracting group A rotavirus (RVA). The World Health Organization (WHO) estimates that Rotavirus causes around 450,000 fatalities, more than 2 million hospitalizations, …
Samuel Darling, a physician practicing at the Canal Zone Hospital in Panama, initially reported histoplasmosis and named the bacterium in 1904. He mistook the bacterium, which resembled Leishmania in tissues, for a parasite. Histoplasma capsulatum is a thermally dimorphic fungus that occurs as a mold in the environment and at …
Von Behring and Kitasato discovered an agent in the blood capable of neutralizing diphtheria toxin in 1890. The term ‘Antikörper,’ or antibodies, was used in investigations the following year to describe the agent’s capacity to distinguish between two immunological compounds. As a result, the substance that causes the creation of …
Hepatic Lipase belongs to the lipase gene family, which also includes pancreatic lipase, Hepatic Lipase, and endothelial lipase. In humans, the Hepatic Lipase (HL) gene is found on chromosome 15 (q15–q22). It is more over 60 kb in length, with eight introns and nine exons accounting for 1.6 kb. Hepatic …
