The Mother-Infant Study Cohort (MISC): Methodology, challenges, and baseline characteristics. PLoS One 2018; 13:e0198278. [PMID: 29851999 PMCID: PMC5978878 DOI: 10.1371/journal.pone.0198278] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2017] [Accepted: 05/16/2018] [Indexed: 12/16/2022] Open
Abstract
BACKGROUND The United Arab Emirates (UAE) exhibits alarming high prevalence of Non-Communicable Diseases (NCDs) and their risk factors. Emerging evidence highlighted the role of maternal and early child nutrition in preventing later-onset NCDs. The objectives of this article are to describe the design and methodology of the first Mother and Infant Study Cohort (MISC) in UAE; present the baseline demographic characteristics of the study participants; and discuss the challenges of the cohort and their respective responding strategies. METHODS The MISC is an ongoing two-year prospective cohort study which recruited Arab pregnant women in their third trimester from prenatal clinics in Dubai, Sharjah and Ajman. Participants will be interviewed six times (once during pregnancy, at delivery, and at 2, 6, 12 and 24months postpartum). Perinatal information is obtained from hospital records. Collected data include socio-demographic characteristics, lifestyle, dietary intake and anthropometry; infant feeding practices, cognitive development; along with maternal and infant blood profile and breast milk profile. RESULTS The preliminary results reported that 256 completed baseline assessment (mean age: 30.5±6.0 years; 76.6% multiparous; about 60% were either overweight or obese before pregnancy). The prevalence of gestational diabetes was 19.2%. Upon delivery, 208 women-infant pairs were retained (mean gestational age: 38.5±1.5 weeks; 33.3% caesarean section delivery; 5.3% low birthweight; 5.7% macrosomic deliveries). Besides participant retention, the main encountered challenges pertained to cultural complexity, underestimation the necessary start-up time, staff, and costs, and biochemical data collection. CONCLUSIONS Despite numerous methodological, logistical and sociocultural challenges, satisfactory follow-up rates are recorded. Strategies addressing challenges are documented, providing information for planning and implementing future birth cohort studies locally and internationally.

Harke SM, Khadke SP, Ghadge AA, Manglekar AS, Shah SS, Diwan AG, Kuvalekar AA. Adipocytokines and anthropometric measures in type 2 diabetics. Diabetes Metab Syndr 2017; 11 Suppl 1:S273-S276. [PMID: 28087246 DOI: 10.1016/j.dsx.2016.12.043] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/12/2016] [Accepted: 12/27/2016] [Indexed: 11/15/2022]
Abstract
AIM Type 2 diabetes mellitus has assumed pandemic proportions worldwide. Aggressive management of hyperglycemia in diabetics is a primary goal of treatment. We have previously reported favorable effects of oral hypoglycemic agents on adipocytokines. Aim of the present study was to investigate the relationship of adipocytokines with anthropometric measures and biochemical parameters in type 2 diabetics. METHODS Clinically diagnosed type 2 diabetics and age, gender matched healthy volunteers were recruited for study. Anthropometric measurements like height, weight, waist-circumference, hip-circumference were recorded and BMI, waist-hip ratio were calculated. Fasting blood samples were collected from participants and sera were analyzed for glucose, glycated haemoglobin, total cholesterol, SGOT, SGPT, insulin, adiponectin and leptin. Correlation of adipocytokines with anthropometric and biochemical parameters was assessed in healthy and diabetic individuals. RESULTS BMI and WHR in diabetics were significantly higher than healthy population. BMI did not show significant association with adipocytokines. Diabetic males with WHR≥0.9 showed negative association with adiponectin and positive association with leptin. WC did not show significant association with adipocytokines in males. Irrespective of WC, healthy females exhibited positive association with leptin. Diabetic females with WC≥88cm showed leptin to be positively associated with WC. Such association of adipocytokines with WHR was not detected in females. CONCLUSIONS Body fat distribution can be considered as a parameter in assessing adipokine imbalance. Central adiposity is a better measure of adipokine imbalance than BMI. Abdominal obesity in diabetics correlates with altered levels of adipocytokines indicating its importance in diabetic individuals.

Abu-Farha M, Melhem M, Abubaker J, Behbehani K, Alsmadi O, Elkum N. ANGPTL8/Betatrophin R59W variant is associated with higher glucose level in non-diabetic Arabs living in Kuwaits. Lipids Health Dis 2016; 15:26. [PMID: 26864934 PMCID: PMC4750355 DOI: 10.1186/s12944-016-0195-6] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2015] [Accepted: 02/03/2016] [Indexed: 12/02/2022] Open
Abstract
Background ANGPTL8 (betatrophin) has been recently identified as a regulator of lipid metabolism through its interaction with ANGPTL3. A sequence variant in ANGPTL8 has been shown to associate with lower level of Low Density Lipoprotein (LDL) and High Density Lipoprotein (HDL). The objective of this study is to identify sequence variants in ANGPTL8 gene in Arabs and investigate their association with ANGPTL8 plasma level and clinical parameters. Methods A cross sectional study was designed to examine the level of ANGPTL8 in 283 non-diabetic Arabs, and to identify its sequence variants using Sanger sequencing and their association with various clinical parameters. Results Using Sanger sequencing, we sequenced the full ANGPTL8 gene in 283 Arabs identifying two single nucleotide polymorphisms (SNPs) Rs.892066 and Rs.2278426 in the coding region. Our data shows for the first time that Arabs with the heterozygote form of (c.194C > T Rs.2278426) had higher level of Fasting Blood Glucose (FBG) compared to the CC homozygotes. LDL and HDL level in these subjects did not show significant difference between the two subgroups. Circulation level of ANGPTL8 did not vary between the two forms. No significant changes were observed between the various forms of Rs.892066 variant and FBG, LDL or HDL. Conclusion Our data shows for the first time that heterozygote form of ANGPTL8 Rs.2278426 variant was associated with higher FBG level in Arabs highlighting the importance of these variants in controlling the function of betatrophin.
