No full textShear stress and oxygen in placental vascular development
No full textThe placenta is an essential organ for a successful pregnancy as it develops to establish effective fetal and maternal blood supplies and materno-fetal gas exchange, both of which are crucial for fetal growth. Abnormal development of the structural components of the placenta are known to be associated with pregnancy complications including fetal growth restriction (FGR) and pre-eclampsia. The overall aim of this thesis is to understand how the placental structural aberrations observed in FGR pregnancies impact placental haemodynamics and materno-fetal gas exchange. In order to accomplish this aim, both in silico and in vitro experimental models are employed to analyse the interactions between placental structure and function in normal and FGR pregnancies.The thesis commences with an in silico study which aims to predict how the structure of the placenta impacts on the mechanical shear stress sensed by endothelial cells that form the walls of placental capillaries. A computational model of feto-placental circulation,with structure parameterised with previously published morphometric data from normal and FGR pregnancies, was used to predict placental microvascular blood flow and shear stress in normal and FGR placentae. The model predicts an elevated microvascular shear stress in FGR placentae in comparison to normal placentae and that the main parameters influencing the elevated shear stress in FGR placentae are placental volume, vascular density, radius and length of individual vascular branches. Shear stress cannot be directly measured in vivo, however, the anatomical model of the placenta considered here provides the first predictions of the magnitude and distribution of shear stress in normal and FGR placentae. The next step is to determine whether this mechanical stress can impact on endothelial cell behaviours. Using an in vitro shear stress experiment, the predicted placental microvascular shear stresses were applied to vascular endothelial cells. These endothelial cells migrated more slowly and more persistently when they were exposed to the shear stresses of FGR conditions, suggesting that normal function of endothelial cells is impaired in FGR placentae, compromising the process of blood vessel formation. We, therefore, propose a vicious cycle in FGR pregnancy, where the elevated shear stress resulting from abnormal vascular structure undermines blood vessel formation, aggravating pre-existing vascular structure abnormalities. The morphology based feto-placental haemodynamic model is extended in two ways. First the model is extended to provide a complete model of the entire fetal circulation. This allows prediction of scenarios relevant to fetal survival in a multi-scale approach, including the interaction between fetal blood pressures, cardiac output and the shear stress in the placental capillaries. Using data from the literature we explore the impact of placental resistance due to structural abnormalities on fetal cardiac function. Then, we take steps toward a personalised approach to modelling the feto-placental circulation by analysing the chorionic vascular network in normal and FGR placentae. We confirm that this network contributes to overall placental resistance in individuals, and quantify how the characteristics of this network impact on placental function in FGR. Finally, in order to understand how the placental villous structure affects on placental exchange function, a 3D computational model of placenta representing the whole organ has been developed. Normal and FGR villous structure were parameterised as reported in previous morphometric studies. The reduced villous density in FGR placentae negatively impacts the maternal blood flow velocity into intervillous space (IVS), resulting in impaired materno-fetal gas exchange and fetal growth.This thesis demonstrates the influence of placental villous and vascular structure on placental vascular shear stress and materno-fetal oxygen exchange, and contributes to the understanding of the pathophysiology of fetal growth in FGR pregnancies. It provides a concept that the in vivo physiological data, that are difficult to assess, could be predicted by developing a replica of biological system computationally

Nutrition in transition: historical cohort analysis summarising trends in under- and over-nutrition among pregnant women in a marginalised population along the Thailand-Myanmar border from 1986 to 2016
No full textThe objective of the present study is to summarise trends in under- and over-nutrition in pregnant women on the Thailand-Myanmar border. Refugees contributed data from 1986 to 2016 and migrants from 1999 to 2016 for weight at first antenatal consultation. BMI and gestational weight gain (GWG) data were available during 2004-2016 when height was routinely measured. Risk factors for low and high BMI were analysed for <18·5 kg/m2 or ≥23 kg/m2, respectively. A total of 48 062 pregnancies over 30 years were available for weight analysis and 14 646 pregnancies over 13 years (2004-2016) had BMI measured in first trimester (<14 weeks' gestational age). Mean weight at first antenatal consultation in any trimester increased over the 30-year period by 2·0 to 5·2 kg for all women. First trimester BMI has been increasing on average by 0·5 kg/m2 for refugees and 0·6 kg/m2 for migrants, every 5 years. The proportion of women with low BMI in the first trimester decreased from 16·7 to 12·7 % for refugees and 23·1 to 20·2 % for migrants, whereas high BMI increased markedly from 16·9 to 33·2 % for refugees and 12·3 to 28·4 % for migrants. Multivariate analysis demonstrated low BMI as positively associated with being Burman, Muslim, primigravid, having malaria during pregnancy and smoking, and negatively associated with refugee as opposed to migrant status. High BMI was positively associated with being Muslim and literate, and negatively associated with age, primigravida, malaria, anaemia and smoking. Mean GWG was 10·0 (sd 3·4), 9·5 (sd 3·6) and 8·3 (sd 4·3) kg, for low, normal and high WHO BMI categories for Asians, respectively.</p
The cropping systems of the Central Dry Zone of Myanmar: Productivity constraints and possible solutions
No full textAvailable online 06 December 2018The Central Dry Zone (CDZ) of Myanmar is home to an estimated 12 million people, provides 35% of Myanmar's grain cropping, but is underdeveloped and food-insecure. We examined the cropping systems of the CDZ to understand the biophysical drivers of those systems, the need for change to improve productivity and sustainability, and how future research and extension might be framed to best serve the rural communities. Data were sourced from (i) published empirical studies and web-based documents produced by the Myanmar Government and international agencies and (ii) a face to face survey of 190 Central Dry Zone farmers. Our analysis indicates that CDZ cropping systems have low productivity which threatens sustainability and future production. Farmers practice traditional cultivation and remove crop residues to use as animal feed, which together deplete soil organic matter reserves and expose the soil to physical degradation. The soils are generally coarse-textured with low water retention, high leaching potential and nutritionally deficient. Nutrient inputs from farm-yard manure and mineral fertiliser are also low. As a consequence, crop nutrient deficiencies are widespread across the CDZ and a major productivity constraint. Mineral-fertiliser use is increasing however, but farmers are conscious of the need for high-quality advice on how best to use these inputs. A narrow range of crops is grown in the CDZ with ca. 80% of the land used to grow pulse and oilseed legumes and sesame and sunflower, but few cereals. The lack of crop diversity exposes farmers to market price fluctuations and the lack of balance between broadleaf and cereal crops results in disease and yield loss. Climate changes further threaten the sustainability and economic viability of grain cropping with increasing temperatures, more erratic rainfall and fewer but more intense rainfall events during the monsoon. Consequences are more floods and dry periods and increased risk of soil erosion. The imperative now is to transition the upland cropping of Myanmar's CDZ to embrace the basic elements of conservation agriculture, i.e. crop diversity, effective weed control, in situ retention of crop residues, optimised crop nutrition and minimal-to-zero soil disturbance, to sustainably increase crop water use-efficiency and system productivity.David F.

Detection of Signal for Radar Navigational System Using MATLAB
No full textThis paper aims to evaluate the performance of target
detection in the presence of sea clutter. Radar detection of a
target against a background of unwanted clutter due to echoes
from sea clutter or land is a problem of interest in the radar field.
Radar detector has been developed by assuming the radar clutter
is Gaussian distributed. However, as technology emerges, the
radar distribution is seen to deviates from the Gaussian
assumption. Thus, detectors designs based on Gaussian
assumption are no longer optimum for detection in non-Gaussian
nature. The theory of target detection in Gaussian distributed
clutter has been well established and the closed form of the
detection performances can be easily obtained. However, that is
not the case in non-Gaussian clutter distributions. The operation
of radar detection is determined by radar detection theory with
different types of Swerling target models; such as Swerling I, II,
III, IV and V. By using MATLAB, these signal detection
techniques are developed
A mixed methods evaluation of Advanced Life Support in Obstetrics (ALSO) and Basic Life Support in Obstetrics (BLSO) in a resource-limited setting on the Thailand-Myanmar border [version 1; peer review: 2 approved]
No full textBackground: Short emergency obstetric care (EmOC) courses have demonstrated improved provider confidence, knowledge and skills but impact on indicators such as maternal mortality and stillbirth is less substantial. This manuscript evaluates Advanced Life Support in Obstetrics (ALSO) and Basic Life Support (BLSO) as an adult education tool, in a protracted, post-conflict and resource-limited setting. Methods: A mixed methods evaluation was used. Basic characteristics of ALSO and BLSO participants and their course results were summarized. Kirkpatrick’s framework for assessment of education effectiveness included: qualitative data on participants’ reactions to training (level 1); and quantitative health indicator data on change in the availability and quality of EmOC and in maternal and/or neonatal health outcomes (level 4), by evaluation of the post-partum haemorrhage (PPH) related maternal mortality ratio (MMR) and stillbirth rate in the eight years prior and following implementation of ALSO and BLSO. Results: 561 Thailand-Myanmar border health workers participated in ALSO (n=355) and BLSO (n=206) courses 2008-2020. Pass rates on skills exceeded 90% for both courses while 50% passed the written ALSO test. Perceived confidence significantly improved for all items assessed. In the eight-year block preceding the implementation of ALSO and BLSO (2000-07) the PPH related MMR per 100,000 live births was 57.0 (95%CI 30.06-108.3)(9/15797) compared to 25.4 (95%CI 11.6-55.4)(6/23620) eight years following (2009-16), p=0.109. After adjustment, PPH related maternal mortality was associated with birth before ALSO/BLSO implementation aOR 3.825 (95%CI 1.1233-11.870), migrant (not refugee) status aOR 3.814 (95%CI 1.241-11.718) and attending ≤four antenatal consultations aOR 3.648 (95%CI 1.189-11.191). Stillbirth rate per 1,000 total births was 18.2 (95%CI 16.2-20.4)(291/16016) before the courses, and 11.1 (95%CI 9.8-12.5)(264/23884) after, p=0.038. Birth before ALSO/ BLSO implementation was associated with stillbirth aoR 1.235 (95%CI 1.018-1.500). Conclusions: This evaluation suggests ALSO and BLSO are sustainable, beneficial, EmOC trainings for adult education in protracted, post-conflict, resource-limited settings
