Pregnancy-associated Malaria
Pregnancy-associated malaria (PAM) or placental malaria is a presentation of malaria in pregnancy which is life-threatening to both pregnant women and unborn fetuses. * PAM occurs when a pregnant woman contracts malaria, generally as a result of ''Plasmodium falciparum'' infection, and because she is pregnant, is at greater risk of associated complications such as placental malaria''.'' Placental malaria interferes with the transmission of vital substances through the fetal placenta, which can result in stillbirths, miscarriages, and dangerously low birth weights''.'' * Prevention and treatment of malaria are essential components of prenatal care in tropical and subtropical geographic areas affected by malaria, and thus has received much international attention. Signs and symptoms Symptoms of malaria include malaise, headaches, fatigue, fever, muscle aches, abdominal pain, nausea and vomiting. More severe cases may present with seizures and even coma. Women affected by PAM that h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fetus
A fetus or foetus (; : fetuses, foetuses, rarely feti or foeti) is the unborn offspring of a viviparous animal that develops from an embryo. Following the embryonic development, embryonic stage, the fetal stage of development takes place. Prenatal development is a continuum, with no clear defining feature distinguishing an embryo from a fetus. However, in general a fetus is characterized by the presence of all the major body organs, though they will not yet be fully developed and functional, and some may not yet be situated in their final Anatomy, anatomical location. In human prenatal development, fetal development begins from the ninth week after Human fertilization, fertilization (which is the eleventh week of Gestational age (obstetrics), gestational age) and continues until the childbirth, birth of a newborn. Etymology The word ''wikt:fetus#English, fetus'' (plural ''wikt:fetuses#English, fetuses'' or rarely, the solecism ''wikt:feti#English, feti''''Oxford English Dict ...

Upregulated
In biochemistry, in the biological context of organisms' regulation of gene expression and production of gene products, downregulation is the process by which a cell decreases the production and quantities of its cellular components, such as RNA and proteins, in response to an external stimulus. The complementary process that involves increase in quantities of cellular components is called upregulation. An example of downregulation is the cellular decrease in the expression of a specific receptor in response to its increased activation by a molecule, such as a hormone or neurotransmitter, which reduces the cell's sensitivity to the molecule. This is an example of a locally acting (negative feedback) mechanism. An example of upregulation is the response of liver cells exposed to such xenobiotic molecules as dioxin. In this situation, the cells increase their production of cytochrome P450 enzymes, which in turn increases degradation of these dioxin molecules. Downregulation or ...

Plasmodium Malariae
''Plasmodium malariae'' is a parasitic protozoan that causes malaria in humans. It is one of several species of ''Plasmodium'' parasites that infect other organisms as pathogens, also including ''Plasmodium falciparum'' and '' Plasmodium vivax'', responsible for most malarial infection. Found worldwide, it causes a so-called "benign malaria", not nearly as dangerous as that produced by ''P. falciparum'' or ''P. vivax''. The signs include fevers that recur at approximately three-day intervals – a '' quartan fever'' or ''quartan malaria'' – longer than the two-day (tertian) intervals of the other malarial parasite. History Malaria has been recognized since the Greek and Roman civilizations over 2,000 years ago, with different patterns of fever described by the early Greeks. In 1880, Alphonse Laveran discovered that the causative agent of malaria is a parasite. Detailed work of Golgi in 1886 demonstrated that in some patients there was a relationship between the 72-hour life ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clindamycin
Clindamycin is a lincosamide antibiotic medication used for the treatment of a number of bacterial infections, including osteomyelitis (bone) or joint infections, pelvic inflammatory disease, strep throat, pneumonia, acute otitis media (middle ear infections), and endocarditis. It can also be used to treat acne, and some cases of methicillin-resistant ''Staphylococcus aureus'' (MRSA). In combination with quinine, it can be used to treat malaria. It is available by mouth, by injection into a vein, and as a cream or a gel to be applied to the skin or in the vagina. Common side effects include nausea and vomiting, diarrhea, skin rashes, and pain at the site of injection. It increases the risk of hospital-acquired ''Clostridioides difficile'' colitis about fourfold and thus is only recommended for use when other antibiotics are not appropriate. It appears to be generally safe in pregnancy. It is of the lincosamide class and works by blocking bacteria from making protein. ...

Quinine
Quinine is a medication used to treat malaria and babesiosis. This includes the treatment of malaria due to ''Plasmodium falciparum'' that is resistant to chloroquine when artesunate is not available. While sometimes used for nocturnal leg cramps, quinine is not recommended for this purpose due to the risk of serious side effects. It can be taken by mouth or intravenously. Malaria resistance to quinine occurs in certain areas of the world. Quinine is also used as an ingredient in tonic water and other beverages to impart a bitter taste. Common side effects include headache, tinnitus, ringing in the ears, vision issues, and sweating. More severe side effects include deafness, thrombocytopenia, low blood platelets, and an irregular heartbeat. Use can make one more prone to sunburn. While it is unclear if use during pregnancy carries potential for fetal harm, treating malaria during pregnancy with quinine when appropriate is still recommended. Quinine is an alkaloid, a natural ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Artemisia Annua
''Artemisia annua'', also known as sweet wormwood, sweet annie, sweet sagewort, annual mugwort or annual wormwood, is a common type of wormwood native to temperate Asia, but naturalized in many countries including scattered parts of North America. The chemical compound artemisinin, which is isolated from ''A. annua'', is a medication used to treat malaria. Discovery of artemisinin and its antimalarial properties by the Chinese scientist Tu Youyou led to the award of the 2011 Lasker Prize and 2015 Nobel Prize in Physiology or Medicine. Description ''Artemisia annua'' belongs to the plant family of ''Asteraceae'' and is an annual short-day plant. Its stem is erect and brownish or violet-brown. The plant itself is hairless and naturally grows from 30 to 100 cm tall, although in cultivation plants can reach a height of 200 cm. The leaves of ''A. annua'' have a length of 3–5 cm and are divided by deep cuts into two or three small leaflets. The intensive aromatic ...

Insecticide Treated Nets
Insecticides are pesticides used to kill insects. They include ovicides and larvicides used against insect eggs and larvae, respectively. The major use of insecticides is in agriculture, but they are also used in home and garden settings, industrial buildings, for vector control, and control of insect parasites of animals and humans. Acaricides, which kill mites and ticks, are not strictly insecticides, but are usually classified together with insecticides. Some insecticides (including common bug sprays) are effective against other non-insect arthropods as well, such as scorpions, spiders, etc. Insecticides are distinct from insect repellents, which repel but do not kill. Sales In 2016 insecticides were estimated to account for 18% of worldwide pesticide sales. Worldwide sales of insecticides in 2018 were estimated as $ 18.4 billion, of which 25% were neonicotinoids, 17% were pyrethroids, 13% were diamides, and the rest were many other classes which sold for less than 10% ...

Sulfadoxine/pyrimethamine
Sulfadoxine/pyrimethamine, sold under the brand name Fansidar, is a combination medication used to treat malaria. It contains sulfadoxine (a sulfonamide) and pyrimethamine (an antiprotozoal). For the treatment of malaria it is typically used along with other antimalarial medication such as artesunate. In areas of Africa with moderate to high rates of malaria, three doses are recommended during the second and third trimester of pregnancy. Side effects include diarrhea, rash, itchiness, headache, and hair loss. Rarely a severe allergic reaction or rash such as toxic epidermal necrolysis, may occur. It is not generally recommended in people with a sulfonamide allergy or significant liver or kidney disease. It works by blocking malaria's ability to use folinic acid. Sulfadoxine/pyrimethamine was initially approved for medical use in the United States in 1981. It is on the World Health Organization's List of Essential Medicines. It is not commercially available in the United Stat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mefloquine
Mefloquine, sold under the brand name Lariam among others, is a medication used to prevent or treat malaria. When used for prevention it is typically started before potential exposure and continued for several weeks after potential exposure. It can be used to treat mild or moderate malaria but is not recommended for severe malaria. It is taken by mouth. Common side effects include vomiting, diarrhea, headaches, sleep disorders, and a rash. Serious side effects include potentially long-term mental health problems such as depression, hallucinations, and anxiety and neurological side effects such as poor balance, seizures, and ringing in the ears. It is therefore not recommended in people with a history of mental health problems or epilepsy. It appears to be safe during pregnancy and breastfeeding. Mefloquine was developed by the United States Army in the 1970s and came into use in the mid-1980s. It is on the World Health Organization's List of Essential Medicines. It is av ...

Chloroquine
Chloroquine is an antiparasitic medication that treats malaria. It works by increasing the levels of heme in the blood, a substance toxic to the malarial parasite. This kills the parasite and stops the infection from spreading. Certain types of malaria, resistant strains, and complicated cases typically require different or additional medication. Chloroquine is also occasionally used for amebiasis that is occurring outside the intestines, rheumatoid arthritis, and lupus erythematosus. While it has not been formally studied in pregnancy, it appears safe. It is taken by mouth. It was studied to treat COVID-19 early in the COVID-19 pandemic, pandemic, but these studies were largely halted in the northern summer of 2020, and the National Institutes of Health, NIH does not recommend its use for this purpose. Common side effects include muscle problems, loss of appetite, diarrhea, and skin rash. Serious side effects include problems with vision, muscle damage, seizures, and aplas ...
