Aim: To evaluate plasma/urine/hair Lead (Pb), Cadmium (Cd), Gadolinium (Gd), Arsenic (As), Mercury (Hg), Cobalt (Co), Vanadium (V), Titanium (Ti), Sulfur (S), Chromium (Cr), Silver (Ag), Molybdenum (Mo), Boron (B), Lithium (Li), and Nickel (Ni) levels in women with premature ovarian insufficiency (POI) and to compare the results with those of healthy subjects. Methods: This prospective study will be included 50 women with idiopathic premature ovarian insufficiency and 50 controls. The blood/urine/hair for analyses will be obtained at the early follicular phase of the menstrual cycle and plasma Lead (Pb), Cadmium (Cd), Gadolinium (Gd), Arsenic (As), Mercury (Hg), Cobalt (Co), Vanadium (V), Titanium (Ti), Sulfur (S), Chromium (Cr), Silver (Ag), Molybdenum (Mo), Boron (B), Lithium (Li), and Nickel (Ni) levels will be measured using inductively coupled plasma-mass spectrometry.

Preterm labor is one of the problems of obstetrics, and is one of the leading cause of neonatal morbidity and mortality. The incidence of preterm birth is around 7 to 9 %. The preterm baby is prone to respiratory, renal, neurologic and gastrointestinal problems. The correct diagnosis should be followed by the early administration of the most effective tocolytic agent with least side effects for both mother and fetus. Nifedipine, a calcium channel blocker, has gained a world-wide popularity recently since it has the least side-effects on both mother and fetus. In the present study, we aimed to evaluate the success rate of tocolytic agent 'nifedipine' on the spontaneous preterm labor of singeton pregnant women with intact amnionic membrane.

This case-control study will be conducted all over the country (in Persian, Kurd, Azari, Arab, Lor, Bakhtiari, Baluch, Turkman, Qashqai, Gilak and in Muslims, Christians, Jewish, and Zoroastrian). the investigators intend to recruit patients (men 60≥ years of age and women 70≥ years of age) who underwent coronary angiography. Patients with coronary artery stenosis more than 75% (or left-main stenosis more than 50%) are defined as case group and patients with normal angiography are considered as the control group. at the same time, the prevalence of premature coronary artery disease in patients with positive angiography will be calculated.

Several positive physiological and behavioural outcomes have been observed in preterm infants exposed to music therapy during their stay at Neonatal Intensive Care Units (NICU). There is ample evidence in the literature showing that brief exposure to music can lead to superior performance on a host of cognitive tasks in laboratory settings in children, adolescent and adults. However, till date no study has examined the cognitive benefits of NICU music therapy in preterm infants. Further habituation tests have been employed to examine cognitive functioning in infants in laboratory setting but the same test have not been employed as a measure to examine early cognitive functioning in preterm infants. This project will be carried out to examine the benefits of NICU music therapy on the cognitive functioning of preterm infants born at 27- 33 weeks of gestational age. A randomized controlled research design will be employed to compare cognitive functioning between the treatment and control group at 18 - 24 months of corrected gestational age. The treatment group will be exposed to music therapy during their stay in NICU and the controlled group will be exposed to all standardized care available at our institution except music therapy. Habituation tests will be used to examine cognitive functioning of the preterm infants in groups at 18 - 24 months of gestational age.

Prematurity is the leading cause of mortality and perinatal morbidity. Despite the many preventive measures and use of tocolytic therapy, the incidence of premature births has not decreased in recent decades. In 2010 the preterm birth rate (single child, born alive) was still 5.5% in France and 11% in the population of Reunion. In 50% of cases, premature birth is related to spontaneous premature labor layout without rupture of amniotic membranes, called threat of premature birth.The threat of premature birth, defined by the combination of cervical modifications and regular and painful uterine contractions from 22 weeks of amenorrhea and 36 weeks of amenorrhea + 6days, is the major cause of hospitalization in pathological pregnancies services. But all threat of premature delivery situations do not cause premature delivery. In our service, only 30% of patients hospitalized for threat of premature delivery give birth prematurely in accordance with published international data. The diagnosis of threat of premature delivery is difficult and it is still not possible to differentiate a "false labour" of a "real labour". Currently the diagnosis of threat of premature delivery in routine is based on the combination of vaginal examination, the ultrasound, cervical length, but this strategy lacks specificity. In absence of prognostic tool for predicting more reliably the risk of premature delivery in situation of threat of premature delivery, the medical cares are maximalist.: hospitalization, conducting paraclinical investigations, prescription of tocolytics treatments and conducting antenatal corticotherapy. it seems particularly necessary to identify more efficient prognostic criteria that the clinic and ultrasound for judging the severity of threat of premature delivery in other words to predict the risk of premature delivery to adapt and adjust the care of patients after diagnosis of threat of premature delivery.

The prediction of preterm birth is beneficial because it initiates early treatment to minimize risk. It defines a population at risk to provide particular treatment and may lead us to a better understanding the mechanisms of preterm birth. The understanding of the mechanisms and etiology consequently leads to the possibility of early intervention and effective management aiming at preventing preterm birth. Five most common interventions for preventing and treating preterm birth are antibiotics, cervical cerclage, bed rest, progesterone, and tocolytic therapy. However, there are insufficient evidence showing the efficacy of cerclage and bed rest; antibiotics may only delay but not prevent the preterm birth; the use of certain tocolytics needs to be considered against the possible adverse effects. The early detection of pregnant women with high risk for preterm delivery would be the ideal solution to prevent preterm birth. However, to date, there is inadequate literature and little knowledge of diagnosis, treatment, prevention and prediction of preterm birth.

This study is to compare the maternal and neonatal outcomes in the patients with PPROM who are managed at home versus those managed at hospital, half the patients will be managed at home and the other half will be managed inpatient.

Preterm infants account for 6 % of all live-births in western societies. Scientific evidence can be found for altered palatal morphology in the short term among preterm children. Oral intubation and orogastric feeding might be contributing factors to these alterations, but it has not been examined whether in the absence of these interventions preterm infants' palates are altered a priori as compared to term infants, e.g. due to immaturity of the bones or due to immaturity of oral function. Because of contradictory results, lack of longitudinal and high quality standard studies, the scientific evidence is also to weak to answer the question whether premature birth without or with a history of orotracheal intubation and orogastric feeding causes permanent alteration of orofacial development. The aim of the present study, therefore is to investigate in consideration of perinatal, biometrical, nutritional, functional and parental parameters.

Premature infants, especially those less than 1250 gm at birth are extremely difficult to feed. For unknown physiologic reasons oral feeding also called enteral feeding is not well tolerated in these immature babies. Because of this challenge these infants require intravenous fluids solution called parenteral nutrition (TPN). Intravenous nutrition is inadequate because it cannot supply sufficient calories for growth both of body and brain. The composition of intravenous nutrition is also toxic to the liver. For those reasons it is very important to achieve adequate enteral nutrition in premature infants as soon as possible after birth. However the best feeding method for those babies has not been defined. Since premature babies are unable to suck and swallow properly, feeding is administered by a tube inserted into the infant's stomach. The timing between feeds is inconsistent. Some infants are fed every 3 hours, whereas others are fed every 4 hours. The purpose of this study is to determine which feeding method is better. We hypothesize that feeding every 4 hours by allowing more time for digestion will improve feeding tolerance in premature infants. In addition it will also facilitate discontinuation of TPN sooner, thus causing less side effects.
