    The purpose of this paper is to discuss the investigator\u27s reflections, both prospective and retrospective, on the process and experience of conducting a mini-ethnographic case study research in Nigeria. The research titled “Exploring barriers to women entrepreneurs in Enugu State Nigeria” was written to add to the body of knowledge on barriers facing some small-scale women entrepreneurs in the marketplaces in Nigeria. A mini-ethnographic case study design was used for this study, this methodology is a combination of ethnography and case study research that can assist a researcher to gain an in-depth understanding of a phenomenon. The data collection methods used for this study included open-ended semi-structured interviews, direct observation, reflective journaling, and field notes. Reflection enables investigators to engage in self-analysis throughout the research process. Reflections and experiences in the three marketplaces where the research took place, including interactions with the gatekeepers as well as the women entrepreneurs who shared their lived experiences, will be discussed

    Isotropic apparent diffusion coefficient mapping of postnatal cerebral development

    Diffusion-weighted imaging (DWI) allows us to image the motion of tissue water. This has been used to demonstrate acute ischaemia. Diffusion imaging is also sensitive to water movement along neuronal tracts. Our objective was to map brain maturation in vivo using maps of apparent diffusion coefficient (ADC). We studied 22children without neurological disease aged between 2 and 720days. MRI was performed at 1.5tesla. Multislice single-shot echoplanar DWI was performed at b 0 and 1000s/mm2. ADC maps were generated automatically and measurements were performed in the basal ganglia, frontal and temporal white matter and the pons. There was a decrease over time in water diffusion in the areas examined, most marked in the frontal (0.887-1.898×10-3mm2/s) and temporal (1.077-1.748×10-3mm2/s)lobes. There was little change, after an initial decrease, in the basal ganglia (0.690-1.336×10-3mm2/s). There was a difference in water diffusion between the anterior (0.687-1.581×10-3mm2/s) and posterior (0.533-1.393×10-3mm2/s) pons. These changes correlate well with those observed in progressive myelination: the increased water content probably reflects incomplete myelination and the decrease with time in water motion reflects the increase in myelinated brai

    Determination of saturation factors in 31P NMR spectra of the developing human brain

    In order to assess the influence of longitudinal relaxation on previously reported variations in 31P NMR signals during brain development, we used an accelerated two-point technique to determine T1 at 2.35 Tesla in 8 min. Comparison between 10 normal neonates (age range 37-46 weeks postconception) and 10 healthy infants (age range 80-157 weeks postconception) indicated that T1 does not vary substantially during the first year of life, except in the phosphomonoester (PME) region of the spectra. T1 of total PME decreases with age which we could explain by its variable multicomponent nature: The signal from (unresolved) components at the downfield shoulder of PME (attributed mostly to phosphorylethanolamine at 6.72 ppm) with a T1 of at least 6.4 s decreases with age relative to contributions from other phosphomonoester compounds resonating predominantly at the upfield side of the peak (approximately 6.3 ppm), with T1 below 2.9 s. Because the T1 heterogeneity of PME may depend on its relative composition, quantitative 31P NMR spectroscopy may require an assessment of the influence of longitudinal relaxation on the signal amplitudes in each measurement

    Neonatology/Paediatrics – Guidelines on Parenteral Nutrition, Chapter 13

    There are special challenges in implementing parenteral nutrition (PN) in paediatric patients, which arises from the wide range of patients, ranging from extremely premature infants up to teenagers weighing up to and over 100 kg, and their varying substrate requirements. Age and maturity-related changes of the metabolism and fluid and nutrient requirements must be taken into consideration along with the clinical situation during which PN is applied. The indication, the procedure as well as the intake of fluid and substrates are very different to that known in PN-practice in adult patients, e.g. the fluid, nutrient and energy needs of premature infants and newborns per kg body weight are markedly higher than of older paediatric and adult patients. Premature infants <35 weeks of pregnancy and most sick term infants usually require full or partial PN. In neonates the actual amount of PN administered must be calculated (not estimated). Enteral nutrition should be gradually introduced and should replace PN as quickly as possible in order to minimise any side-effects from exposure to PN. Inadequate substrate intake in early infancy can cause long-term detrimental effects in terms of metabolic programming of the risk of illness in later life. If energy and nutrient demands in children and adolescents cannot be met through enteral nutrition, partial or total PN should be considered within 7 days or less depending on the nutritional state and clinical conditions

    Enhancing primary care support for informal carers: a scoping study with professional stakeholders

    Get PDF
    Informal carers (i.e. people who provide unpaid care to family and/or friends) are crucial in supporting people with long‐term conditions. Caring negatively impacts on carers’ health and experiences of health services. Internationally and nationally, policies, legislation, professional guidance and research advocate for health and care services to do more to support carers. This study explored the views of health and social care providers, commissioners and policy makers about the role and scope for strengthening health service support for carers. Twenty‐four semi‐structured interviews, with 25 participants were conducted, audio‐recorded, transcribed verbatim and analysed by thematic analysis. Three main themes emerged: (a) identifying carers, (b) carer support, and (c) assessing and addressing carer needs. Primary care, and other services, were seen as not doing enough for carers but having an important role in identifying and supporting carers. Two issues with carer identification were described, first people not self‐identifying as carers and second most services not being proactive in identifying carers. Participants thought that carer needs should be supported by primary care in collaboration with other health services, social care and the voluntary sector. Concerns were raised about primary care, which is under enormous strain, being asked to take on yet another task. There was a clear message that it was only useful to involve primary care in identifying carers and their needs, if benefit could be achieved through direct benefits such as better provision of support to the carer or indirect benefit such as better recognition of the carer role. This study highlights that more could be done to address carers’ needs through primary care in close collaboration with other health and care services. The findings indicate the need for pilots and experiments to develop the evidence base. Given the crucial importance of carers, such studies should be a high priority

    Targeting human milk fortification to improve very preterm infant growth and brain development: study protocol for Nourish, a single-center randomized, controlled clinical trial.

    Human milk is recommended for very preterm infants, but its variable macronutrient content may contribute to undernutrition during a critical period in development. We hypothesize that individually targeted human milk fortification is more effective in meeting macronutrient requirements than the current standard of care.MethodsWe designed a single-center randomized, controlled trial enrolling 130 infants born DiscussionWe expect this trial to provide important data regarding the effectiveness of individually targeted human milk fortification in the neonatal intensive care unit (NICU).Trial registrationNCT03977259 , registered 6 June, 2019

    SCAMP:standardised, concentrated, additional macronutrients, parenteral nutrition in very preterm infants: a phase IV randomised, controlled exploratory study of macronutrient intake, growth and other aspects of neonatal care

    <p>Abstract</p> <p>Background</p> <p>Infants born <29 weeks gestation are at high risk of neurocognitive disability. Early postnatal growth failure, particularly head growth, is an important and potentially reversible risk factor for impaired neurodevelopmental outcome. Inadequate nutrition is a major factor in this postnatal growth failure, optimal protein and calorie (macronutrient) intakes are rarely achieved, especially in the first week. Infants <29 weeks are dependent on parenteral nutrition for the bulk of their nutrient needs for the first 2-3 weeks of life to allow gut adaptation to milk digestion. The prescription, formulation and administration of neonatal parenteral nutrition is critical to achieving optimal protein and calorie intake but has received little scientific evaluation. Current neonatal parenteral nutrition regimens often rely on individualised prescription to manage the labile, unpredictable biochemical and metabolic control characteristic of the early neonatal period. Individualised prescription frequently fails to translate into optimal macronutrient delivery. We have previously shown that a standardised, concentrated neonatal parenteral nutrition regimen can optimise macronutrient intake.</p> <p>Methods</p> <p>We propose a single centre, randomised controlled exploratory trial of two standardised, concentrated neonatal parenteral nutrition regimens comparing a standard macronutrient content (maximum protein 2.8 g/kg/day; lipid 2.8 g/kg/day, dextrose 10%) with a higher macronutrient content (maximum protein 3.8 g/kg/day; lipid 3.8 g/kg/day, dextrose 12%) over the first 28 days of life. 150 infants 24-28 completed weeks gestation and birthweight <1200 g will be recruited. The primary outcome will be head growth velocity in the first 28 days of life. Secondary outcomes will include a) auxological data between birth and 36 weeks corrected gestational age b) actual macronutrient intake in first 28 days c) biomarkers of biochemical and metabolic tolerance d) infection biomarkers and other intravascular line complications e) incidence of major complications of prematurity including mortality f) neurodevelopmental outcome at 2 years corrected gestational age</p> <p>Trial registration</p> <p>Current controlled trials: <a href="http://www.controlled-trials.com/ISRCTN76597892">ISRCTN76597892</a>; EudraCT Number: 2008-008899-14</p

    Less is more: Antibiotics at the beginning of life

    Get PDF
    Antibiotic exposure at the beginning of life can lead to increased antimicrobial resistance and perturbations of the developing microbiome. Early-life microbiome disruption increases the risks of developing chronic diseases later in life. Fear of missing evolving neonatal sepsis is the key driver for antibiotic overtreatment early in life. Bias (a systemic deviation towards overtreatment) and noise (a random scatter) affect the decision-making process. In this perspective, we advocate for a factual approach quantifying the burden of treatment in relation to the burden of disease balancing antimicrobial stewardship and effective sepsis management
