Cuvinte cheie vitamină D sarcină deficienţă Introduction Appropriate nutrition is an renal cancer vitamin d condition papiloma intraduttale health.

The birth, growth, development, reproduction and senescence under physiological conditions can be achieved without diminishing the role of other important aspects that influence them, only with the support of an optimal diet which is a fundamental requirement nowadays, considering that health and nutritional status are in a permanent interdependence. A particular physiological situation through the impact on the individual, the family, but also on society is the gestation state, the current concepts and orientations referring both to the preconception nutrition of the woman in the fertile period and to the nutritional intake during the pregnancy, targeting its effects on the conception product.

The gestational state is a period of intense fetal growth and development, and of major adaptive changes in the maternal body. Malnutrition, both in the sense of deficit and excess, is associated with unfavorable results of pregnancy evolution, which is why it is of particular importance to evaluate, monitor and permanently improve the nutritional status of women, both during preconception period and during pregnancy and lactation.

The effects of inadequate nutrition reflect on the expression of genes, influencing the renal cancer vitamin d of certain diseases in childhood and adulthood 1. Nutritional supervision and counseling should be continued during pregnancy and lactation.

Optimally, this can be done through a team approach that includes obstetrician physician, specialized prenatal nutrition counseling, and dietitian specialized in perinatal nutrition. In the context of the clinical specialties of the Romanian healthcare network, the perinatal nutrition approach could be achieved through the collaboration of the obstetrician and the specialists in diabetes and nutrition graduate of the master studies in nutrition and food safetybecause university studies and the development of dietetics will bring an essential plus of competence to this team.

Knowing the phases of the gestation period, in which the needs of certain nutrients are increased and their absence has a serious impact on fetal growth and development, allows for the adoption in due time of concrete preventive rules.

The beneficial effect of preventive therapy is renal cancer vitamin d the present time a certainty and a method of primary prophylaxis. The effects of food deficiencies on the function of reproductive organs are of particular importance from the point of view of the late disorders they cause and their persistence for a long time after the normalization of food intake.

Malnutrition is considered renal cancer vitamin d risk factor for amenorrhea and infertility. Late ovulation and menstrual cycle disorders are the main effects of inadequate intake, which is also associated with an increased risk of recurrent miscarriage, intrauterine growth restriction and congenital malformations.

In the second half of pregnancy, a serious food deficiency of the mother can cause spontaneous abortion. Moderate food deficiencies cause premature delivery and fetal hypotrophy. Inadequate nutrition in the first part of pregnancy may cause, depending on the severity of the deficiency, either abortion, or alteration of embryonic structures.

The imbalance of the enzymatic components exerts the renal cancer vitamin d obvious teratogenic effect. Vitamin D — or calciferol — is a generic term comprising a group of liposoluble compounds having a skeleton composed of four cholesterol molecules.

The hydroxyvitamin D is the major circulating form of vitamin D. The half-life is weeks compared to 24 hours of the inactive vitamin D form. The 1,dihydroxyvitamin D binds to intracellular receptors present in target tissues and regulates gene transcription, a mechanism that is realized with a single receptor VDRuniversally expressed in nucleated cells.

Vitamin D is obtained from dairy products, vegetables, fish oil and dietary supplements. The endogen vitamin D is produced by direct exposure to the sun. Previtamin D is synthesized non-enzymatically in skin from 7-dehydrocholesterol during exposure to ultraviolet light in sunlight. Previtamin D is subsequently subjected to temperature-dependent conformational rearrangement, forming vitamin D3 colecalciferol.

This system is excessively effective, with the estimated occasional exposure of only arms and face to the sun being equivalent to the ingestion of international units IU per day. However, it is difficult to assess the duration of daily exposure required to obtain the equivalent of oral vitamin D supplementation, as there are many variables represented by skin type, latitude, season and time of the day 7,8.

Prolonged exposure of the skin to sunlight cannot produce toxic amounts of vitamin D3 due to the photoconversion of previtamin D3 and vitamin D3 in inactive metabolites lumisterol, tahisterol, 5,6-transvitamin D and suprasterol 1 and 2 9, In addition, sunlight induces melanin production that reduces vitamin D3 production in the skin.

Children, people with disabilities and the elderly may experience inadequate sun exposure and the dermis of papiloma humano tiene curacion over the age of 70 years renal cancer vitamin d renal cancer vitamin d no longer able to efficiently convert vitamin D. At Nordic latitudes, there is not enough radiation for this conversion, especially in the cold season. For these reasons, in the United States of America, milk, instant milk for infants, breakfast cereals, renal cancer vitamin d some other renal cancer vitamin d are renal cancer vitamin d with vitamin D3 or synthetic vitamin D2 ergocalciferolwhich is derived from the effect of radiation on ergosterol found in plants, in plankton, or in molds.

In other countries, cereals and bakery products are often also fortified with vitamin D. Vitamin D present in the diet is incorporated into the mycelium, absorbed by enterocytes, and then stored in kilomicrons.

Biochemical mechanisms Vitamin D from diet or dermal synthesis is biologically inactive and requires enzyme, liver and kidney conversion to generate active metabolites.

Riscurile și complicațiile cauzate de o deficiență de vitamină D Pacienții cu niveluri scăzute renal cancer vitamin d vitamina D sunt predispuși la dezvoltarea următoarelor complicații: Rahitism la copii Dezvoltarea bolilor cu componentă autoimună Transformarea tumorală a celulelor Dezvoltarea episoadelor depresive și anxioase Alterarea structurii și funcției țesutului muscular, cartilajului și tendoanelor Perturbarea dentiției Creșterea riscului de instalare a unor boli precum artrita reumatoidă, scleroza multiplă, hipertensiune arterială f. Diagnosticarea deficitului de vitamină D Referitor la concentrațiile plasmatice ale vitaminei D, există controverse asupra nivelurilor deficiente și suficiente. Acest domeniu coincide cu prevederile existente în ghidurile europene. Concentrația de 1, OH 2-vitamină D reflectă activitatea 1-alfa-hidroxilazei renale. De obicei, concomitent este util a se determina și nivelul de parathormon.

Renal cancer vitamin d vitamin D is directed to the liver linked to the vitamin D binding protein, associated permanently with kilomicrons and lipoproteins. Along with endogenously synthesized vitamin D3, exogenous vitamin D is metabolized into the liver, where the hepatic hydroxylase enzyme places a hydroxy group at the position of the vitamin D molecule, resulting in the formation of hydroxyvitamin D 25[OH]D — calcidiol ; hydroxyvitamin D2 has a lower affinity compared to hydroxyvitamin D3 for the vitamin D binding protein.

Therefore, hydroxyvitamin Cancer genetic discrimination has a half-life shorter than hydroxyvitamin D3. In this context, vitamin D2 treatment is not able to grow total serum level of 25 OH D as effective as vitamin D3.

The hydroxyvitamin D2 and D3 produced in the liver enter the circulation and cross the kidneys, linked to the specific protein that has a single binding site for all the D vitamins and all their metabolites.

In the renal tubules, the entry of the 25 OH D-protein binding protein of vitamin D into the cells is facilitated by receptor-mediated endocytosis At least two proteins working in tandem are involved in this process: cubilin and megalina 12, Cubilin and megaline expressed in the proximal renal tubule have multiple binding receptors that facilitate extracellular ligand uptake.

The deficiency of any of these proteins results in increased urinary excretion of 25 OH D and, consequently, renal cancer vitamin d experimental models, resulting in 1,dihydroxyvitamin D deficiency and bone damage
