Filter by:Preterm birth is a leading cause of neonatal mortality and morbidity. Cervical insufficiency is one factor implicated in the complex mechanisms involved in spontaneous preterm birth. Trans-abdominal insertion of a cervical cerclage suture can be used to treat cervical insufficiency. Growing evidence support that laparoscopic cerclage procedures are safe and effective. Still, many aspects of the laparoscopic cerclage remains uncertain. Therefore, the investigators plan to study the obstetric outcome from the first and subsequent pregnancies after laparoscopic cerclage in a Danish cohort from Aarhus University Hospital in a 10 years' period.
Ventilated neonates frequently require supplementary oxygen to allow for adequate oxygen delivery to the tissues and normal cell metabolism. Oxygen treatment should be monitored carefully as both excessive and inadequate dosing can have detrimental effects for the infants. Hypoxia (giving too little oxygen) increases mortality and later disability whereas hyperoxia (giving too much oxygen) increases the risk of complications such as retinopathy of prematurity and lung disease. Although very preterm and low birth weight infants represent the majority of ventilated neonates, more mature infants may also require mechanical ventilation at birth and provision of supplementary oxygen. Therefore, they may suffer from complications related to hypoxia or hyperoxia. Hence, their oxygen saturation levels and the amount of the inspired oxygen concentration provided should be continuously monitored. Oxygen control is traditionally monitored and adjusted manually by the nurse looking after the infant. Closed-loop automated oxygen control (CLAC) is a more recent approach that involves the use of a computer software incorporated into the ventilator. The software uses an algorithm that automatically adjusts the amount of inspired oxygen to maintain oxygen saturation levels in a target range. Evidence suggests that CLAC increases the time spent in the desired oxygen target range, decreases the duration of hypoxia and hyperoxia and reduces the number of manual adjustments required by clinical staff. However previous studies have been limited to very small infants. With this study the investigators aim to evaluate the effectiveness of CLAC in ventilated infants born at 34 weeks gestation and beyond. The achievement of oxygen saturation targets and the number of manual adjustments required will be compared between periods of CLAC and manual control in a cohort of patients that has not been included in previous studies and could also benefit from the intervention. The investigators will also evaluate if CLAC reduces investigations performed to ventilated babies(blood gases, X-rays).
The objective of this study is to perform ultrasound Doppler measurements to evaluate the hemodynamic changes associated with different methods of placental transfusion (Intact umbilical cord milking, cut- umbilical cord milking and delayed cord clamping) in premature neonates over the first days of life.
Preterm infants are at risk of free radical mediated diseases from oxidative stress (OS) injury. Melatonin (MEL) is a powerful antioxidant and scavenger of free radicals. In preterm neonates, melatonin deficiency has been reported. Several studies tested the efficacy of melatonin to counteract oxidative damage in diseases of newborns such as chronic lung disease, perinatal brain injury, necrotizing enterocolitis, retinopathy of prematurity and sepsis, giving promising results. In these studies, the dosages of melatonin varied over a wide range. The present study was designed to test the hypothesis that oral administration of melatonin reduced OS and consequentially, the occurrence of intraventricular haemorrhage (IVH), necrotizing enterocolitis (NEC), retinopathy of prematurity (ROP) and bronchopulmonary dysplasia (BPD) in preterm newborns.
Women who had an adverse pregnancy outcome (APO), such as preeclampsia, preterm birth, or gestational diabetes, have a higher risk for heart disease. Some of the extra risk for heart disease after APOs is thought to be caused by inflammation. Investigators will randomize women who had an APO in the past 3 years to receive an anti-inflammatory supplement or serve as a time control. Investigators will compare blood pressure, arterial stiffness, blood vessel reactivity, and blood markers of inflammation between women who did and did not receive the supplement. Investigators will determine women's attitudes about taking a dietary supplement and measure whether the participants who receive the supplement take all or most of the doses.
This study evaluates the brain and renal oxygenation using near infrared spectroscopy in preterm infants with persistent ductus arteriosus
ROP is a preventable cause of blindness in premature infants. It is routinely screened for by using an indirect ophthalmoscope, a scleral depressor, and a condensing lens. This method of screening can cause significant cardiorespiratory distress to infants. A new camera (Optos California) has recently been used to image infants with different severities of ROP. The Optos California is capable of capturing up to 200 degrees of retina in a single image without contact with the eye. The non eye contact nature of the Optos California may cause less distress to infants who are due a ROP screening examination. The present study is to compare the impact of ROP screening examination between the Optos retinal camera and conventional binocular indirect ophthalmoscopy using cardiorespiratory indices (such as heart rate, oxygen saturations, blood pressure, and respiratory rate) as a measure of distress.
Non-invasively neonatal cardiac output can be measured by multiple methods, but the gold standard still remains conventional echocardiography. It is accurate, but needs a long training for new users to assess cardiac function. Continuous-wave Doppler ultrasound monitor USCOM is a relatively new monitor which can perform faster and less complex cardiac function measurement, also it is easier for the operator to get trained. The aim of the study is to assess the level of agreement between cardiac output measured with conventional echocardiography and with USCOM, to present normal ranges for neonates of different gestational age and to look for early signs of hemodynamic changes during sepsis.
Globally, 15% of all babies, amounting to 20 million infants each year, are born low birthweight (LBW), defined less than 2500 grams (5.5 lbs). Compared to normal weight infants, LBW infants are at higher risk of morbidity, mortality, and poor growth (Risnes et al 2011; Larroque et al 2001; WHO 2006). The main causes of LBW are preterm birth, intrauterine growth restriction (IUGR), or their combination. Unfortunately, there is a paucity of information around feeding practices and optimal feeding strategies for this population, particularly for LBW infants who struggle with breastfeeding or growth. This study hopes to address these gaps.
