Filter by:unit (NICU); however prolonged MV is known to be associated with serious complications including ventilator associated pneumonia, blood stream infections, bronchopulmonary dysplasia (BPD) and periventricular leukomalacia. At the same time, extubation failure increases morbidities and mortality. Hatch et al (2016) in their prospective study on 162 infants described adverse events in 40% of intubations and severe complications including need for CPR in 9%. Reintubations are frequently associated with hypoxemia, bradycardia, fluctuations in blood pressures and cerebral perfusion. Each intubation attempt increases the risk of traumatic injury to the upper airway, lung atelectasis and infections. Thus, there is a clear need to establish objective criteria that would help avoid extubation failure and the need for reintubation. In recent years, a new imaging application has been introduced in neonatal practice-lung ultrasound (LUS), an accurate and reliable technique for the lung evaluation. LUS is safe, non-ionizing, easy to operate, and low-cost tool. The evaluation of lungs is performed in real-time, on the bedside and without anesthetic drugs. Lung aeration could be assessed in dynamics without extra radiation to the infant. Ultrasound findings combined with clinical information could be used for the prognosis of successful extubation in premature infants.
We are going to assess an ability of speech perception in voice in children diagnosed with ADHD (Attention Deficit Hyperactivity Disorder), comparing to normal control group. This is an attempt to understand the factors influencing on this ability.
Zinc is important in biology and allows the proper function of proteins in living organisms. Severe zinc deficiency in animals and humans over long periods of time can therefore cause adverse effects. In the UK, the zinc status of most people is adequate, but about 20% of the population, especially adolescents in deprived communities and vegetarians/vegans, are likely marginally zinc deficient. Because potatoes are a favoured food in adolescents and vegetarians/vegans, the investigators have improved the zinc content of Saxon potatoes by biofortification, which involves spraying potato plant leaves with zinc salts. The potato zinc concentration is about three times the level in unfortified potatoes of the same variety. This level of zinc can boost the zinc intake of people who are marginally zinc deficient so that they become zinc adequate. Indeed, in rat studies, the investigators have shown that addition of some zinc-biofortified potato to a low zinc diet improves the zinc and health status of the animals. In the present study, the investigators propose to investigate whether the potato biofortification can improve the zinc and health status of volunteers. Because most of the volunteers (healthy adult men and women after the menopause) might have normal or variable zinc status at recruitment, it might not be possible to see the benefits of the potato diets and therefore, the investigators shall reduce the zinc intake of all 45 participants to 1 mg Zn/d for a period of two weeks prior to feeding 15 randomly selected individuals the biofortified potato diets (4 mg Zn/d) for two weeks. Zinc and health status will be measured by blood tests before and after zinc depletion and after feeding the potato diets. Results will be compared with data from 15 volunteers eating unfortified potato diets with a daily placebo and 15 volunteers consuming the unfortified potato diets with a zinc supplement (18 mg/d) as a positive control.
Study will examine the metabolic, physiological and cardiovascular changes by intake of New Zealand blackcurrant extract at rest and during moderate-intensity treadmill walking in healthy males.
The investigator will determine the effectiveness of psychological skill training on quantitative EEG in athletes before the competition.
A number of processed foods particularly those high in protein and based on whey protein are high in advanced glycation end products (AGEs). AGEs are the result of a chemical reaction between mainly sugar and protein when they are heated together (known as the Maillard reaction). Whey protein is routinely derived via high temperature processing methods which produce AGEs. AGEs are absorbed during digestion and high circulating concentrations of AGEs are associated with adverse health effects such as dementia and the metabolic syndrome. In this study we aim to firstly ascertain the habitual level of AGE intake in the diet via a dietary questionnaire and equate this to both metabolic health and cognition at baseline. Volunteers will then be given a milkshake with either a high or low AGE content on either a high or low fat background. AGEs are usually ingested as part of a processed food diet which can be high in fat and it is necessary to separate the effects of these two food types. We will test these effects in a young and older group of volunteers with low and higher levels of circulating AGEs respectively. Circulating levels of hormones, glucose and lipids in the blood will be measured as indicators of metabolic health. Cognitive tests will be carried out to assess the impact of AGEs on episodic memory.
The progress of labour is traditionally determined by regular vaginal examinations (VEs) to assess the cervix (neck of the womb) and the baby's head position. Such examinations can be uncomfortable and risk causing infection to the baby or mother's womb. The findings are subjective, can be unreliable and cannot be recorded for later review and analysis. The novel, non-intrusive "transperineal ultrasound" technique has been developed utilising existing scanning machines normally found on a delivery unit, with the ultrasound probe placed outside the woman's vagina. This allows objective, recordable measurements creating images that can be captured and stored electronically. This is a prospective longitudinal observational cohort study in nulliparous term (37-42 weeks) labouring women. This study aims to improve the prediction of intrapartum Caesarean Delivery (ICD). The study contains ultrasound and clinical assessments: Transabdominal Ultrasound to measure: Umbilical and Middle Cerebral Artery Doppler, fetal head position and Amniotic Fluid Index (AFI). Transperineal Ultrasound to assess: Head Perineum Distance (HPD), Caput Succedaneum and moulding. Digital vaginal examination by a caregiver: to measure cervical dilatation. Primary outcome: • Mode of delivery Secondary outcome: • Time to delivery Neonatal outcomes: • Apgar score, cord pH level, gender, fetal birth weight, neonatal unit admission within 24 hours, neonatal morbidity.
Some stimuli, such as sinusoidal networks in motion, or the best known, Necker's cube, are simple visual stimulations generating interpretations of unstable and oscillatory shapes or movements, mutually exclusive. Currently, the explanatory models of these perception phenomena are based on adaptation and learning mechanisms as well as the importance of noise in the perceptual and decision-making system. Often noise is a harmful component, but it can also be a facilitator in perceptual systems: the investigator's eye is always in motion, it is the micro-movements during eye fixation (phase of eye stability). In particular, the role of micro-eye movements has been identified in perceptual systems, and it will be necessary here to relate these micro-movements to the perceptive tilts facing multisable stimuli. However, how to access the perceptive states is a real question, since it has been shown that the participant's transfer of his perceptual state by means of a motor response can alter the very state of the percept. This is why the EEG activity will be analyzed to learn to discriminate the different percepts over time, without disruption of the participant's perceptual exploration endogenous activity.
This is a single site evaluation study of Vitastiq device accuracy in healthy men and women in ratio 1:1 (approximately) aged between 18 and 64 years. A total of 45 Vitastiq personal devices will be used by volunteers for two months. The Vitastiq device will be evaluated during three site visits: on day 1, 29 ± 4 days and 57 ± 4 days. During site visit days, blood sampling will be collected and analysed and readings using Vitastiq device will be performed. Data will be analysed retrospectively to evaluate Vitastiq performance compared to blood tests results.
