    Fasting plasma glucose (FPG) and haemoglobin A1c (HbA1c) are both used to diagnose diabetes, but may identify different people as having diabetes. We used data from 117 population-based studies and quantified, in different world regions, the prevalence of diagnosed diabetes, and whether those who were previously undiagnosed and detected as having diabetes in survey screening had elevated FPG, HbA1c, or both. We developed prediction equations for estimating the probability that a person without previously diagnosed diabetes, and at a specific level of FPG, had elevated HbA1c, and vice versa. The age-standardised proportion of diabetes that was previously undiagnosed, and detected in survey screening, ranged from 30% in the high-income western region to 66% in south Asia. Among those with screen-detected diabetes with either test, the agestandardised proportion who had elevated levels of both FPG and HbA1c was 29-39% across regions; the remainder had discordant elevation of FPG or HbA1c. In most low- and middle-income regions, isolated elevated HbA1c more common than isolated elevated FPG. In these regions, the use of FPG alone may delay diabetes diagnosis and underestimate diabetes prevalence. Our prediction equations help allocate finite resources for measuring HbA1c to reduce the global gap in diabetes diagnosis and surveillance.peer-reviewe

    Two series (aand b) of N-substituted heteroaromatic compounds related to clotrimazole were synthesized. Imidazole ring of the clotrimazole was replaced by 2-methylimidazole in series a, and by 2-methyl-4-nitroimidazole in series b. O-cholortrityl moiety of clotrimazole was also replaced by trityl, mono or dimethoxy trityl. Chemical structures of all the new compounds were confirmed by spec-trophotometric methods. These compounds docked into the active site of MT-CYP51(PDB code, 1E9X) using Autodock tools software which showed good affinity for the enzyme. Antifungal activities of these compounds were evaluated against Trichophyton mentagrophytes, Microsporum gypseumand Candida albicans using SC, SCC and PDAas media, CHCl3and DMSO as solvents and agar dilution assay as method. In this method 1(4-methoxyphenyl-diphenylmethyl)-2-methylimidazole (2), 1[bis-4-methoxyphenyl-phenylmethyl]-2-methyl imidazole (3) and1[4-methoxyphenyl-diphenylmethyl]-2-methyl-4-nitroimidazole (5) showed morethan 75% activity against fungi. In the second step all of the derivatives also were evaluated against Trichophyton rubrum, Microsporum canisand Epidermaphyton floccosum using PDAmedium by agar dilution method. Compound 2showed morethan 75% activity by this method. Then the most active analogue (2) was tested in RPMI 1640 medium which showed desirable biological activity in comparison to clotrimazole

    International audienceAbstract Fasting plasma glucose (FPG) and hemoglobin A1c (HbA1c) are both used to diagnose diabetes, but these measurements can identify different people as having diabetes. We used data from 117 population-based studies and quantified, in different world regions, the prevalence of diagnosed diabetes, and whether those who were previously undiagnosed and detected as having diabetes in survey screening, had elevated FPG, HbA1c or both. We developed prediction equations for estimating the probability that a person without previously diagnosed diabetes, and at a specific level of FPG, had elevated HbA1c, and vice versa. The age-standardized proportion of diabetes that was previously undiagnosed and detected in survey screening ranged from 30% in the high-income western region to 66% in south Asia.
