Gestational diabetes in a developing country, experience of screening at the Aga Khan University Medical Centre, Karachi

In order to determine the prevalence of glucose intolerance in pregnancy, 1267 consecutive women attending the antenatal clinic of the Aga Khan University Medical Centre were subjected to a 75 g glucose challenge followed 2 hr later by plasma glucose determination irrespective of gestation on the first antenatal visit. The test was repeated at 28-32 weeks of gestation if the patients had an abnormal initial screen at less than 28 weeks gestation and a normal glucose tolerance test on diagnostic follow-up and for those who had a risk factor for gestational diabetes and a normal initial screen at less than 28 weeks gestation. The glucose challenge test was abnormal (2 hr plasma glucose greater than 140 mg%) in 8.6% of the screened population. Follow-up oral glucose tolerance test on these patients revealed a prevalence of 3.2% of gestational diabetes and 1.9% of impaired glucose tolerance test based on the modified O\u27Sullivan criteria. Improvement in cost effectiveness of screening programmes was adjudged possible by avoiding glucose tolerance tests in patients with 2 hr plasma glucose value of greater than 170 mg% after a 75 g oral glucose challenge for screening

Assimilation of IRS-P4 (MSMR) meteorological data in the NCMRWF global data assimilation system

Oceansat-1 was successfully launched by India in 1999, with two payloads, namely Multi-frequency Scanning Microwave Radiometer (MSMR) and Ocean Color Monitor (OCM) to study the biological and physical parameters of the ocean. The MSMR sensor is configured as an eight-channel radiometer using four frequencies with dual polarization. The MSMR data at 75 km resolution from the Oceansat-I have been assimilated in the National Centre for Medium Range Weather Forecasting (NCMRWF) data assimilation forecast system. The operational analysis and forecast system at NCMRWF is based on a T80L18 global spectral model and Spectral Statistical Interpolation (SSI) scheme for data analysis. The impact of the MSMR data is seen globally, however it is significant over the oceanic region where conventional data are rare. The dry-nature of the control analyses have been removed by utilizing the MSMR data. Therefore, the total precipitable water data from MSMR has been identified as a very crucial parameter in this study. The impact of surface wind speed from MSMR is to increase easterlies over the tropical Indian Ocean. Shifting of the positions of westerly troughs and ridges in the south Indian Ocean has contributed to reduction of temperature to around 30‡S

Bacteriuria and pregnancy outcome: A prospective hospital-based study in Pakistani women

The prevalence of bacteriuria in Pakistani women and its association with complications of pregnancy was studied. Out of 1579 women, 77 had bacteriuria (4.8%). There was no association of age, gravidity, parity, haemoglobin, pre-eclampsia, mode of delivery, gestational age at delivery, preterm delivery and low birth-weight with presence of bacteriuria. With detection and treatment the pregnancy outcome of women with bacteriuria in pregnancy was the same as that of those without

Spatial analysis of soil parameters in Domagor-Pahuj watershed using Geostatistical methods of GIS

The water and land management is an important aspect in watershed programme increasing the productivity visa-vis sustainability of resources. Watersheds are natural hydraulic entity where water flows in a definite path to a common point. For land use planning of any watershed, soil characterization for its area is very essential and important. This would help in knowing the soil fertility status in watershed area. GIS is a tool that can be effectively used for spatial analysis of soil fertility for a desired geographical area. Domagor-Pahuj watershed is situated in Jhansi district of Bundelkhand region and located between 25o28’ to 25o31’ N latitude and 078o25’ to 078o28’ E longitude. This watershed has a total geographical area of 1 646 ha out of which 1 373 ha area is treatable and consists of three villages namely Domagor, Dikauli and Naya Khera. A total number of 103 representative soil samples were taken from Domagor-Pahuj watershed during May-June 2010. These samples were analyzed for soil parameters like pH, OC, EC, P, K, Zn, B and S. These sample points were geographically referenced and soil maps were generated using Geostatistical interpolation methods in Arc GIS 10. Ordinary and Universal Krigging methods were applied and compared on the basis of RMSE. Out of the two methods applied, ordinary Kriging was found better for prediction of soil EC, P, B and S, whereas universal Krigging was found better for prediction of soil pH, OC, K and Zn. Thus, spatial maps were generated by Ordinary and Universal Krigging methodsfor these soil parameters and hence may be used for soil fertility status and land use planning of Domagor-Pahuj watershed

Field Bund & Border as Alternative Land Use for Forage Production: A Case of Marginal Farmer in Bundelkhand Region of India

In India, if marginal farmers are approached for production of forage grasses in their agricultural lands, the response of the farmers would be straight forward „NO‟ to the forage crops on agricultural lands. The reason is that food grains (cereals & pulses), vegetables, oilseeds, fruits, etc. are grown on agricultural land and get the first preference for family members, while the forage grasses are least preferred, as crops residues are being fed to livestock. More than 60% of the farm produce come from the small farms only. The productivity of the marginal and small farmers is the solution for growing population food needs. Most of the marginal and small farmers cultivate the farm land with the support of their family members and local labour which the quality of the work is higher. They grow multiple crops and sow as soon as they harvest. The last four decades has witnessed a sharp decline in the average size of operational land holdings in India. The average size of operational land holdings has reduced by half from 2.28 ha in 1970-71 to 1.6 ha in 2010-11. Land holdings in the marginal category (less than 1 ha) constitute 67% of the operational holdings in India (2010-11). Marginal and small holdings together, constitute 85% in terms of number of operational holdings and 44% of the operated area in the country. Thus, over the period, the marginal category has emerged as a distinct and dominant class by itself with its average size dwindling to a mere 0.38 ha. (NABARD, 2014). This is the case study of an illiterate & marginal farmer, Shri Vijay Singh Kushwaha (37) S/o shri Dhan Singh resides in Kushwaha Dera at village Parasai (under Babina development block) in Jhansi district of Uttar Pradesh, Bundelkhand region of central India. He used to cultivate only monsoon crops, was the target of an extension programme initiated by ICAR-Central Agroforestry Research Institute, Jhansi in 2011 under the project “Enhancing groundwater recharge and water use efficiency in Semi-Arid Tropics region through watershed interventions, Parasai-Sindh watershed, Jhansi”. The watershed is being developed in consortia mode with ICAR-Central Agroforestry Research Institute, Jhansi, and International Crop Research Institute for Semi-Arid Tropics (ICRISAT), Hyderabad. The watershed comprises three villages namely Parasai, Chhatpur and Bachhauni and located between 250 23‟56‟‟ to 250 27‟ 9.34‟‟ N latitude and 780 19‟ 45.71‟‟ to 780 22‟ 42.57‟‟E longitude. The watershed is about 35 km in the West of the district headquarter. Bundelkhand is prone to severe drought leading to huge migration towards cities in search of livelihoods and the scarcity of green fodder posed as one of the major hindrances for dairy and livestock production activity in the region

Carbon Modeling of Agroforestry Systems at Farmers’ Field in Indo-Gangetic Plains of India

The Indian Green revolution region “Indo-Gangetic Plain” (IGP) comprises of four agro-climatic zones namely lower, middle, upper, and trans gangetic plains covering West Bengal, Bihar, Uttar Pradesh, Delhi, Uttarakhand, Chandigarh, Haryana, Punjab, and some part of Rajasthan state. It covers 169 districts with total geographical area of 43.70 million ha. The Indo-Gangetic plains are one of the most populous regions with its area covering nearly 13% of the total geographical area of the country. It produces about 50% of the total food grains to feed 40% of the population. The continuous cropping of rice-wheat system has degraded the soil health dramatically over the years. Hence, the incorporation of trees in agriculture would be a better option to improve the soil as well as livelihood of the farmers in IGP. Agriculture is the major enterprise of the region that is most vulnerable to climate changes particularly owing to the inadequacy of resources with the smallholder farmers. While, agroforestry has the potential to play a significant role in mitigating the atmospheric accumulation of greenhouse gases (GHG), it also helps smallholder farmers adapt to the changes. These are the reasons for recognizing agroforestry as a viable alternative to prevent and mitigate climate change (Ram Newaj et al., 2014). A considerable proportion of agroforestry area located in IGP and some of the promising tree species like Populus deltoides, Eucalyptus tereticornis, Melia azadirach, Mangifera indica, Dalbergia sissoo, and Acacia nilotica are very common in the farmer’s fields. Keeping this in view, the field survey was carried out to estimate the carbon sequestration potential at a farmer’s field in IGP

Modifiers of the effect of maternal multiple micronutrient supplementation on stillbirth, birth outcomes, and infant mortality: a meta-analysis of individual patient data from 17 randomised trials in low-income and middle-income countries

Background: Micronutrient deficiencies are common among women in low-income and middle-income countries. Data from randomised trials suggest that maternal multiple micronutrient supplementation decreases the risk of low birthweight and potentially improves other infant health outcomes. However, heterogeneity across studies suggests influence from effect modifiers. We aimed to identify individual-level modifiers of the effect of multiple micronutrient supplements on stillbirth, birth outcomes, and infant mortality in low-income and middle-income countries.Methods: This two-stage meta-analysis of individual patient included data from 17 randomised controlled trials done in 14 low-income and middle-income countries, which compared multiple micronutrient supplements containing iron-folic acid versus iron-folic acid alone in 112 953 pregnant women. We generated study-specific estimates and pooled subgroup estimates using fixed-effects models and assessed heterogeneity between subgroups with the χ2 test for heterogeneity. We did sensitivity analyses using random-effects models, stratifying by iron-folic acid dose, and exploring individual study effect.Findings: Multiple micronutrient supplements containing iron-folic acid provided significantly greater reductions in neonatal mortality for female neonates compared with male neonates than did iron-folic acid supplementation alone (RR 0·85, 95% CI 0·75–0·96 vs 1·06, 0·95–1·17; p value for interaction 0·007). Multiple micronutrient supplements resulted in greater reductions in low birthweight (RR 0·81, 95% CI 0·74–0·89; p value for interaction 0·049), small-for-gestational-age births (0·92, 0·87–0·97; p=0·03), and 6-month mortality (0·71, 0·60–0·86; p=0·04) in anaemic pregnant women (haemoglobin \u3c110g/L) as compared with non-anaemic pregnant women. Multiple micronutrient supplements also had a greater effect on preterm births among underweight pregnant women (BMI \u3c18·5 kg/m2; RR 0·84, 95% CI 0·78–0·91; p=0·01). Initiation of multiple micronutrient supplements before 20 weeks gestation provided greater reductions in preterm birth (RR 0·89, 95% CI 0·85–0·93; p=0·03). Generally, the survival and birth outcome effects of multiple micronutrient supplementation were greater with high adherence (≥95%) to supplementation. Multiple micronutrient supplements did not significantly increase the risk of stillbirth or neonatal, 6-month, or infant mortality, neither overall or in any of the 26 examined subgroups.Interpretation: Antenatal multiple micronutrient supplements improved survival for female neonates and provided greater birth-outcome benefits for infants born to undernourished and anaemic pregnant women. Early initiation in pregnancy and high adherence to multiple micronutrient supplements also provided greater overall benefits. Studies should now aim to elucidate the mechanisms accounting for differences in the effect of antenatal multiple micronutrient supplements on infant health by maternal nutrition status and sex.Funding: None

Whispering in our hearts: speaking of another in changing schools

Beneath discussions about race and ethnic relations is an unease, \u27a whispering in our hearts\u27 these debates that need to be understood \u27otherwise\u27. In more recent times, they seem increasingly complex and dangerous as the essential differences that underpin modern notions of identity appear negotiated, contingent, and disjunctive. In this paper, I examine the ways in which teachers and parents in one Melbourne secondary school spoke about these notions in 1988 and 1998. Taking up suggestions in the postcolonial and race literatures, the article argues that the normalised notions which make up these conversations need to be made explicit, and the near silences that negotiate the parameters of these discussions should also be the focus of analysis. While at one level teachers and parents discussed their unease and their excitement about the ways their school had changed, their conversations remained underpinned by taken-for-granted understandings about the ways people belong differently within the school community.<br /

Discourses of antagonism and desire : marketing for international students in neighbourhood schools

This paper explores the consequences of these discourses for the ways that international students are identified and positioned within school communities. My argument is developed in four sections. The first describes my ongoing exploration into the impact of international student programmes in Australia. The second exemplifies my argument: exploring the day-to-day experiences of vice principals in two Victorian government state secondary schools as they market their schools, and examining the systemic and ontological discourses played out within those conversations. The third interrogates discourses of identity and difference, neo-liberalism and nave cosmopolitanism which I find shape teacher conversations about international student programmes. In the final section, I argue that the impact of the discourse formations implicit in teacher talk about international student programmes has been the objectification of international students and their ambivalent inclusion within the school community.<br /

'You were quiet - I did all the marching': Research processes involved in hearing the voices of South Asian girls

This article is available open access through the publisher’s website at the link below. Copyright @ 2011 A B Academic Publishers.This article provides insights into the outcomes of reflection following two interview approaches used to explore narratives of the lived, individual experiences of South-Asian girls living in West London. In attempting to illuminate and re-present the cultural experiences as told by these girls, the choice of interview approach became critical in allowing the voices to be effectively heard (Rogers, 2005). This article therefore considers how a semi-structured interview approach offered valuable insights into the girls' experiences but became constraining for both researcher and participant in unveiling the complexity and depth of their lives. These constraints emerged through reflection by both participants and researcher. As a result of reflexivity during the research process, the researcher moved towards the use of research conversations during the second phase of the study. Ultimately the study revealed how the girls felt empowered by the opportunity to narrate their individual experiences and tell of their lives. In narrating their reflections on being part of the research, there was a clear recognition that the process facilitated the articulation of new voices and ‘multi-voicedness’ (Moen, 2006
