Public Health Intervention
A public health intervention is any effort, policy, or program intended to improve mental and physical health at the population level. Interventions involve social movements that strive to support public health at different levels of society. Public health interventions may be run by a variety of organizations, including governmental health departments and non-governmental organizations (NGOs). Interventions can be personal, community-level, national, and global. Common types of interventions include screening programs, vaccination, food and water supplementation, and health promotion. Common issues that are the subject of public health interventions include obesity, drug, tobacco, and alcohol use, and the spread of infectious disease, e.g. HIV. Public health interventions are distinct from healthcare interventions in terms of their scope, methods, and objectives. Though, both are highly interconnected and necessarily complementary. A policy may meet the criteria of a public he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mental Health
Mental health is often mistakenly equated with the absence of mental illness. However, mental health refers to a person's overall emotional, psychological, and social well-being. It influences how individuals think, feel, and behave, and how they cope with stress, relate to others, and make choices. Mental illness, on the other hand, refers to diagnosable conditions—such as depression, anxiety disorders, or schizophrenia—that disrupt a person's thoughts, mood, behavior, or functioning. It is possible for individuals with mental illness to experience periods of good mental health, just as people without a mental illness may struggle with poor mental well-being at times.[1][2] Mental health encompasses emotional, Psychology, psychological, and social well-being, influencing cognition, perception, and behavior. Mental health plays a crucial role in an individuals daily life when managing stress, engaging with others, and contributing to life overall. According to the World Heal ...

Vertical Transmission
Vertical transmission of symbionts is the transfer of a microbial symbiont from the parent directly to the offspring. Many metazoan species carry symbiotic bacteria which play a mutualistic, commensal, or parasitic role. A symbiont is acquired by a host via horizontal, vertical, or mixed transmission. Fitness benefits Vertical transmission, passage of symbiotic microflora from parents to offspring, is common in species of animals which have parental care. There are fitness benefits in providing youths with established microorganism community early on. # Immune system development: parents microbes prime young immune system. # Disease resistance: because skin is already colonized by parental microbes, pathogen flora has a harder time to establish itself. # Digestive help: parental microbes might help with digestion, as a result, the young ones can survive on a diet which would not meet their nutritious needs otherwise. # Environmental adaptation: microflora might help t ...

Tooth Decay
Tooth decay, also known as caries,The word 'caries' is a mass noun, and is not a plural of 'carie'.'' is the breakdown of teeth due to acids produced by bacteria. The resulting cavities may be a number of different colors, from yellow to black. Symptoms may include pain and difficulty eating. Complications may include periodontal disease, inflammation of the tissue around the tooth, tooth loss and infection or dental abscess, abscess formation. Tooth regeneration is an ongoing Stem-cell therapy, stem cell–based field of study that aims to find methods to reverse the effects of decay; current methods are based on easing symptoms. The cause of cavities is acid from bacteria dissolving the hard tissues of the teeth (Tooth enamel, enamel, dentin and cementum). The acid is produced by the bacteria when they break down food debris or sugar on the tooth surface. Simple sugars in food are these bacteria's primary energy source and thus a diet high in simple sugar is a risk factor. I ...

Water Fluoridation
Water fluoridation is the controlled addition of fluoride to Public water supply, public water supplies to reduce tooth decay. Fluoridated water maintains fluoride levels effective for cavity prevention, achieved naturally or through supplementation. In the mouth, fluoride slows tooth enamel Demineralization (physiology), demineralization and enhances remineralization in early-stage cavities. Defluoridation is necessary when natural fluoride exceeds recommended limits. The World Health Organization (WHO) recommends fluoride levels of 0.5–1.5 mg/L, depending on climate and other factors. In the U.S., the recommended level has been 0.7 mg/L since 2015, lowered from 1.2 mg/L. Bottled water often has unknown fluoride levels. Tooth decay affects 60–90% of schoolchildren worldwide. Fluoridation reduces cavities in children, with Cochrane (organisation), Cochrane reviews estimating reductions of 35% in baby teeth and 26% in permanent teeth when no other fluoride s ...

Spina Bifida
Spina bifida (SB; ; Latin for 'split spine') is a birth defect in which there is incomplete closing of the vertebral column, spine and the meninges, membranes around the spinal cord during embryonic development, early development in pregnancy. There are three main types: spina bifida occulta, meningocele and myelomeningocele. Meningocele and myelomeningocele may be grouped as spina bifida cystica. The most common location is the Lumbar vertebrae, lower back, but in rare cases it may be in the Thoracic vertebrae, middle back or Cervical vertebrae, neck. Occulta has no or only mild signs, which may include a hairy patch, dimple, dark spot or swelling on the back at the site of the gap in the spine. Meningocele typically causes mild problems, with a sac of fluid present at the gap in the spine. Myelomeningocele, also known as open spina bifida, is the most severe form. Problems associated with this form include poor ability to walk, impaired Neurogenic bladder dysfunction, bladder o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Folic Acid
Folate, also known as vitamin B9 and folacin, is one of the B vitamins. Manufactured folic acid, which is converted into folate by the body, is used as a dietary supplement and in food fortification as it is more stable during processing and storage. Folate is required for the body to make DNA and RNA and metabolise amino acids necessary for cell division and maturation of blood cells. As the human body cannot make folate, it is required in the diet, making it an Nutrient#Essential nutrients, essential nutrient. It occurs naturally in many foods. The recommended adult daily intake of folate in the U.S. is 400 micrograms from foods or dietary supplements. Folate in the form of folic acid is used to treat anemia caused by folic acid deficiency, folate deficiency. Folic acid is also used as a supplement by women during pregnancy to reduce the risk of neural tube defects (NTDs) in the baby. NTDs include anencephaly and spina bifida, among other defects. Low levels in early pregna ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Goitre
A goitre (British English), or goiter (American English), is a swelling in the neck resulting from an enlarged thyroid gland. A goitre can be associated with a thyroid that is not functioning properly. Worldwide, over 90% of goitre cases are caused by iodine deficiency. The term is from the Latin ''gutturia'', meaning throat. Most goitres are not cancerous ( benign), though they may be potentially harmful. Signs and symptoms A goitre can present as a palpable or visible enlargement of the thyroid gland at the base of the neck. A goitre, if associated with hypothyroidism or hyperthyroidism, may be present with symptoms of the underlying disorder. For hyperthyroidism, the most common symptoms are associated with adrenergic stimulation: tachycardia (increased heart rate), palpitations, nervousness, tremor, increased blood pressure and heat intolerance. Clinical manifestations are often related to hypermetabolism (increased metabolism), excessive thyroid hormone, an in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iodised Salt
Iodised salt (American and British English spelling differences#-ise, -ize (-isation, -ization), also spelled iodized salt) is Salt#Edible salt, table salt mixed with a minute amount of various iodine salts. The ingestion of iodine prevents iodine deficiency. Worldwide, iodine deficiency affects about two billion people and is the leading preventable cause of Intellectual disability, intellectual and developmental disabilities. Deficiency also causes thyroid gland problems, including endemic goitre. In many countries, iodine deficiency is a major public health problem that can be cheaply addressed by purposely adding small amounts of iodine to the sodium chloride salt. Iodine is a micronutrient and dietary mineral that is naturally present in the food supply in some regions, especially near sea coasts but is generally quite rare in the Earth's crust since iodine is a so-called heavy element, and abundance of chemical elements typically declines with greater atomic mass.

Vitamin Deficiency
Vitamin deficiency is the condition of a long-term lack of a vitamin. When caused by not enough vitamin intake it is classified as a ''primary deficiency'', whereas when due to an underlying disorder such as malabsorption it is called a ''secondary deficiency''. An underlying disorder can have 2 main causes: * Metabolic causes: Genetic defects in enzymes (e.g. kynureninase) involved in the kynurenine pathway of synthesis of niacin from tryptophan can lead to pellagra (niacin deficiency). * Lifestyle choices: Lifestyle choices and habits that increase vitamin needs, such as smoking or drinking alcohol Alcohol may refer to: Common uses * Alcohol (chemistry), a class of compounds * Ethanol, one of several alcohols, commonly known as alcohol in everyday life ** Alcohol (drug), intoxicant found in alcoholic beverages ** Alcoholic beverage, an alco .... Government guidelines on vitamin deficiencies advise certain intakes for healthy people, with specific values for women, men, ...

Food Fortification
Food fortification is the addition of micronutrients (essential trace elements and vitamins) to food products. Food enrichment specifically means adding back nutrients lost during food processing, while fortification includes adding nutrients not naturally present.World Health Organization and Food and Agriculture Organization of the United Nations Guidelines on food fortification with micronutrients. 2006 ited on 2011 Oct 30 Food manufacturers and governments have used these practices since the 1920s to help prevent nutrient deficiencies in populations.

Polio Vaccine
Polio vaccines are vaccines used to prevent poliomyelitis (polio). Two types are used: an inactivated vaccine, inactivated poliovirus given by injection (IPV) and a attenuated vaccine, weakened poliovirus given by mouth (OPV). The World Health Organization (WHO) recommends all children be fully vaccinated against polio. The two vaccines have eliminated polio from most of the world, and reduced the number of cases reported each year from an estimated 350,000 in 1988 to 33 in 2018. The inactivated polio vaccines are very safe. Mild redness or pain may occur at the site of injection. Oral polio vaccines cause about three cases of vaccine-associated paralytic poliomyelitis per million doses given. This compares with 5,000 cases per million who are paralysed following a polio infection. Both types of vaccine are generally safe to give during pregnancy and in those who have HIV/AIDS, but are otherwise well. However, the emergence of circulating vaccine-derived poliovirus (cVDPV), a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bill & Melinda Gates Foundation
The Gates Foundation is an American private foundation founded by Bill Gates and Melinda French Gates. Based in Seattle, Washington, it was launched in 2000 and is reported to be the third largest charitable foundation in the world, holding $77.2 billion in assets as of December 31, 2024.
