Hyperglycemia during pregnancy is thought to cause epigenetic changes in the leptin gene of newborns leading to a potential increased risk for obesity and heart disease. Leptin is sometimes known as the “satiety hormone” because it is released by fat cells to inhibit hunger. By studying both animal models and human observational studies, it has been suggested that a leptin surge in the perinatal period plays a critical role in contributing to long-term risk of obesity. The perinatal period begins at 22 weeks gestation and ends a week after birth.

An ~18kbp deletion, encompassing the entire Rpl38 locus underlies the phenotype in the Tail-short (Ts) mutant mouse. In homozygous state, Ts mice die at around 3–4 days of gestation. Ts/+ heterozygous embryos undergo an anemia and develop skeletal malformations. During the perinatal period ~30% of the heterozygotes die.

These depolarizations activate voltage-dependent calcium channels. They later become hyperpolarizing as the mammal matures. To be specific, in rats, this maturation occurs during the perinatal period when brain stem projects reach the lumbar enlargement. Descending modulatory inputs are necessary for the developmental shift from depolarizing to hyperpolarizing inhibitory postsynaptic potentials.

|
Another critical developmental time window is the perinatal period, the time period immediately before and after birth. It has been shown that maternal diet in late pregnancy and an infant's diet in the beginning weeks can all have significant impacts on gene expression. Therefore, perinatal nutrition is both late-stage in utero nutrition and lactation.

During the perinatal period, the embryo/fetus can contract the virus through the placenta. Gestational diabetes is directly linked with obesity in offspring through adolescence. Additionally, children whose mothers had diabetes are more likely to develop Type II diabetes. Mothers who have gestational diabetes have a high chance of giving birth to very large infants (10 pounds or more).

PIM2 is expressed with high levels in the brain and lymphoid cells. PIM1-3 compound knockout mice that survived the perinatal period showed a large reduction in body size. This suggests that the PIM enzymes are important for body growth. Experiments have implicated that PIM1 and PIM2 are necessary for cytokine-dependent proliferation and survival of lymphocytes.

Extranuclear transmission of viral genomes and symbiotic bacteria is also possible. An example of viral genome transmission is perinatal transmission. This occurs from mother to fetus during the perinatal period, which begins before birth and ends about 1 month after birth. During this time viral material may be passed from mother to child in the bloodstream or breastmilk.

USP18-deficiency is a very rare primary immunodeficiency caused by mutations of the USP18 gene. The inheritance is autosomal recessive. The clinical disease presents in the perinatal period with life-threatening autoinflammation that mimics TORCH infections, but in the absence of infection. The severe inflammation results from a failure to regulate type I IFN activity, and is therefore considered a type I interferonopathy.

It is also produced in perisinusoidal cells in the liver. Liver production predominates in the fetal and perinatal period; renal production predominates in adulthood. It is homologous with thrombopoietin. Exogenous erythropoietin, recombinant human erythropoietin (rhEPO), is produced by recombinant DNA technology in cell culture and are collectively called erythropoiesis-stimulating agents (ESA): two examples are epoetin alfa and epoetin beta.

Polymicrogyria typically forms while the embryo's central nervous system is maturing. Ulegyria is acquired later in development during the perinatal period after neuronal migration has already occurred. It is also suspected that polymicrogyra is genetically linked, whereas ulegyria is caused by environmental factors—namely lack of oxygen. Polymicrogyria can lead to similar conditions that are linked to ulegyria such as mental retardation, cerebral palsy, and epilepsy.
|
|
Ulegyria was found in about 1/3 of patients with defects caused by circulatory disease in the perinatal period. Most clinical observations of the condition report mental retardation, cerebral palsy, and seizures as the main defects. However, milder cases have been reported in which patients that exhibit ulegyria develop relatively normally. The main movement disorders associated with ulegyria that are classified as cerebral palsy are choreoathetosis, dystonia, and ataxia.

An individual that has been exposed to domestic violence is predisposed to the development of PTSD. However, being exposed to a traumatic experience does not automatically indicate that an individual will develop PTSD. There is a strong association between the development of PTSD in mothers that experienced domestic violence during the perinatal period of their pregnancy. Those who have experienced sexual assault or rape may develop symptoms of PTSD.

Male sea lions reach sexual maturity from ages 5 to 7 and don't become territorial until around 9 to 13 years of age. The females arrive in late May bringing in an increase of territorial defense through fighting and boundary displays. After a week births consist most usually of one pup with a perinatal period of 3 to 13 days. Steller sea lions have exhibited multiple competitive strategies for reproductive success.

The 2000 Surgeon's General Report stressed the interdependence of oral health on the overall health and well-being of an individual. Oral health is especially essential during perinatal period and the future development of the child. Proper management of oral health has benefits to both mother and child. Furthermore, lack of understanding or maintenance of good oral health for pregnant women may have adverse effects on them and their children.

Pups from gestating rats exposed to hypergravity (1.8 g) or to normal gravity at the perinatal period were evaluated. By comparison to controls, the hypergravity group had shorter latencies before choosing a maze arm in a T-maze and fewer exploratory pokes in a hole board. During dyadic encounters, the hypergravity group had a lower number of self-grooming episodes and shorter latencies before crossing under the opposing rat.

Breastfeeding research continues to assess prevalence, HIV transmission, pharmacology, costs, benefits, immunology, contraindications, and comparisons to synthetic breast milk substitutes. Factors related to the mental health of the nursing mother in the perinatal period have been studied. While cognitive behavior therapy may be the treatment of choice, medications are sometimes used. The use of therapy rather than medication reduces the infant's exposure to medication that may be transmitted through the milk.

Makrides is a dietician, specialising in translational research on the nutrition and health of mothers and babies. She works on health effects of different dietary supplements, including fatty acids and iron during the perinatal period. Makrides work has led to changes in infant formulae as well as improving food laws internationally (Codex Alimentarius). Most recently Maria was part of an international expert advisory group to comment on the composition of follow-up formulas under review by Codex.

Arsenic exposure through groundwater is highly concerning throughout the perinatal period. Pregnant women are a high-risk population because not only are the mothers at risk for adverse outcomes, but in-utero exposure also poses health risks to the infant. There is a dose-dependent relationship between maternal exposure to arsenic and infant mortality, meaning that infants born to women exposed to higher concentrations, or exposed for longer periods of time, have a higher mortality rate.Rahman, Anisur et al.

The cause of biliary atresia in most infants is not known and it is likely that a number of factors may play a role. Some may be due to a defect in early bile duct development (particularly those with other abnormalities) and some may arise in the perinatal period due to an external cause such as an hepatotropic virus reovirus 3 infection, congenital cytomegalovirus infection, and autoimmunity. However, experimental evidence is insufficient to confirm any of these theories.

Thanatophoric dysplasia is a genetic disorder caused by gain-of- function mutations in FGFR3 that is often fatal during the perinatal period because the child cannot breathe. There are two types. TD type I is caused by a stop codon mutation that is located in part of the gene coding for the extracellular domain of the protein. TD type II is a result of a substitution in a Lsy650Glu which is located in the tyrosine kinase area of FGFR3.

A mother carries her infant on her belly for its first four weeks. After this time, the mother carries her infant on her back, as well. Infants continue to be carried past a year. A mother and her infant tend to avoid other troop members, and the mother may socialize again very slowly.Bardi M, Shimizu K, Fujita S, Borgognini-Tarli S, Huffman MA.

Achondrogenesis, type 1B is a severe autosomal recessive skeletal disorder, invariably fatal in the perinatal period. Achondrogenesis Type 1B, GeneReviews Bookshelf, 2002-2014, L. Bonafé, L. Mittaz-Crettol, D. Ballhausen, and A. Superti-Furga It is characterized by extremely short limbs, a narrow chest and a prominent, rounded abdomen. The fingers and toes are short and the feet may be rotated inward. Affected infants frequently have a soft out-pouching around the belly-button (an umbilical hernia) or near the groin (an inguinal hernia).

Almost all infants with ROP have a gestational age of 31 weeks or less (regardless of birth weight) or a birth weight of 1250 g (2.76 lbs) or less; these indications are generally used to decide whether a baby should be screened for ROP, but some centres, especially in developing countries extend birth weight screening criteria to 1500 g (3.3 lbs). Any premature baby with severe illness in perinatal period (Respiratory distress syndrome, sepsis, blood transfusion, Intra ventricular haemorrhage, apnoeic episodes, etc.) may also be offered ROP screening.

Other mutations, such as those affecting acetylcholinesterase and acetyltransferase, can also cause the expression of CMS, with the latter being associated specifically with episodic apnea. These syndromes can present themselves at different times within the life of an individual. They may arise during the fetal phase, causing fetal akinesia, or the perinatal period, during which certain conditions, such as arthrogryposis, ptosis, hypotonia, ophthalmoplegia, and feeding or breathing difficulties, may be observed. They could also activate during adolescence or adult years, causing the individual to develop slow-channel syndrome.

This is consistent with other findings among low-SES Mexican-American women and their infants. Women with prenatal depressive symptoms are more likely to develop postpartum depression, which can also have negative consequences on children, such as emotional and behavior problems, attachment difficulties, cognitive deficits, physical growth and development, and feeding habits and attitudes. Related, maternal depression affects parenting behaviors, which in turn could affect child outcomes. Thus, women’s mental health throughout the perinatal period should be a priority, not only to support women, but also to promote optimal functioning for their infants.

Leonard Birnie Strang FRCP (13 May 1925 in East Kilbride – 24 June 1997) was a Scottish born, British professor of Paediatric sciences and was a Secretary of the Paediatric Committee of the Royal College of Physicians. He was considered an outstanding clinical observer, contributing to the first accounts of harlequinism and of catecholamine secretion in neuroblastoma. However it was his later work that Leonard Strang became famous, leading a team over two decades studying pulmonary vasculature in the perinatal period and even more the central role that secretion of lungs containing fluid plays in lung formation and preparation for birth.

There are no life-threatening complications after the perinatal period (around the time of birth) and the skin conditions persist but to a lesser degree of severity. Individuals have a favourable prognosis as symptoms can be managed and past the infancy stage are not life-threatening. The red skin edema improves after a three-week period but the ichthyosis scaling persists. Asthma has been recorded in some cases later on in the individual's life and sign of atopic dermatitis persist, follicular hyperkeratosis and small amounts of scaling at the scalp that goes on into adulthood but otherwise the individual continues a healthy life.

Ulegyria is a diagnosis used to describe a specific type of cortical scarring in the deep regions of the sulcus that leads to distortion of the gyri. Ulegyria is identified by its characteristic "mushroom-shaped" gyri, in which scarring causes shrinkage and atrophy in the deep sulcal regions while the surface gyri are spared. This condition is most often caused by hypoxic- ischemic brain injury in the perinatal period. The effects of ulegyria can range in severity, although it is most commonly associated with cerebral palsy, mental retardation and epilepsy. N.C. Bresler was the first to view ulegyria in 1899 and described this abnormal morphology in the brain as “mushroom-gyri.

The Collaborative Perinatal Project (abbreviated CPP), also known as the National Collaborative Perinatal Project (or NCPP), was a multisite prospective cohort study designed to identify the effects of complications during either pregnancy or the perinatal period on birth and child outcomes, especially neurological disorders such as cerebral palsy. It was conducted by the National Institute of Neurological and Communicative Disorders and Stroke on over 55,000 pregnant mothers at 12 sites across the United States from 1959 to 1965. It is one of the largest and broadest epidemiological studies in American history; according to Mark Klebanoff, "No U.S.-based study of pregnancy and childhood conducted before or since has matched its size, breadth and depth".

Perinatal mortality (PNM) refers to the death of a fetus or neonate and is the basis to calculate the perinatal mortality rate. Variations in the precise definition of the perinatal mortality exist, specifically concerning the issue of inclusion or exclusion of early fetal and late neonatal fatalities. The World Health Organization defines perinatal mortality as the "number of stillbirths and deaths in the first week of life per 1,000 total births, the perinatal period commences at 28completed weeks (196 days) of gestation, and ends seven completed days after birth", but other definitions have been used. The UK figure is about 8 per 1,000 and varies markedly by social class with the highest rates seen in Asian women.

Mental stress in men is associated with various complications which can affect men's health: high blood pressure and subsequent cardiovascular morbidity and mortality, cardiovascular disease, erectile dysfunction (impotence) and possibly reduced fertility (due to reduced libido and frequency of intercourse). Fathers experience stress during the time shortly before and after the time of birth (perinatal period). Stress levels tend to increase from the prenatal period up until the time of birth, and then decrease from the time of birth to the later postnatal period. Factors which contribute to stress in fathers include negative feelings about the pregnancy, role restrictions related to becoming a father, fear of childbirth, and feelings of incompetence related to infant care.

A term with the same meaning is the "antepartum" (from Latin ante "before" and parere "to give birth") Sometimes "antepartum" is however used to denote the period between the 24th/26th week of gestational age until birth, for example in antepartum hemorrhage.patient.info » PatientPlus » Antepartum Haemorrhage Last Updated: 5 May 2009The Royal Women’s Hospital > antepartum haemorrhage Retrieved on 13 Jan 2009 The perinatal period (from Greek peri, "about, around" and Latin nasci "to be born") is "around the time of birth". In developed countries and at facilities where expert neonatal care is available, it is considered from 22 completed weeks (usually about 154 days) of gestation (the time when birth weight is normally 500 g) to 7 completed days after birth.Definitions and Indicators in Family Planning.
