Simultaneous measurement of HbA1C and Hemoglobin by Turbidimetric inhibition immunoassay from a single punch of dried blood spot samples
Hemoglobin and glycosylated hemoglobin (HbA1C) are frequently monitored health indicators in population based studies for information about the status of nutrition and diabetes control. We present here possibly for the first time the findings of simultaneous estimation of Hemoglobin and HbA1C on Dried blood spot (DBS) samples by a single test. Validation was done by turbidimetric inhibition immunoassay (TINIA) using Roche Integra 400 plus instrument. Paired whole blood and DBS samples were tested for HbA1C estimation by Integra 400 plus. Total hemoglobin values obtained during HbA1C estimation were compared with hemoglobin values estimated by Coulter AcT 5 Diff CP Hematology counter. Agreement in HbA1C and hemoglobin values between paired whole blood and DBS samples was found to be high with R2 values of 0.994 and 0.9349, respectively. Intra- and inter- assay precision was found to be within 10% for both parameters. Values obtained after assaying DBS samples prepared by spotting proficiency samples on Whatman 903 protein saver cards demonstrated acceptable standard deviation indices resulting in successful participation in EQAS programs for both these parameters. The results reveal the potential of TINIA for simultaneous estimation of hemoglobin and HbA1C from a single punch of the DBS samples

Exploring Inclusive MedTech Innovations for Resource-Constrained Healthcare in India
The potential of inclusive medical technological innovations to create access to affordable and appropriate products and services for local healthcare systems in developing countries has emerged as a critical area of academic and policy debates. This research contributes to these debates by studying the key factors, actors and their interactions influencing the development and adoption of three innovative diagnostic devices to resolve the healthcare needs of the local population in the Indian healthcare systems. It highlights the critical role of the state in influencing the development and adoption of inclusive MedTech innovations in resource-constraint settings. It further reveals that the availability of finance facilitated the early-stage development of innovations. At the same time, collaborative arrangements with a diverse set of stakeholders contributed to late-stage development and adoption of innovations in the local healthcare systems. This research also expands on the conceptualization of inclusivity in the MedTech sector by providing a holistic interpretation of affordability as reducing healthcare costs over a longer period through access to early diagnostics rather than the purchase cost of a product. These research findings have significant implications for innovation and healthcare policies that can help to resolve the challenges of accessible healthcare in developing countries
MetaGT : A pipeline for de novo assembly of metatranscriptomes with the aid of metagenomic data
While metagenome sequencing may provide insights on the genome sequences and composition of microbial communities, metatranscriptome analysis can be useful for studying the functional activity of a microbiome. RNA-Seq data provides the possibility to determine active genes in the community and how their expression levels depend on external conditions. Although the field of metatranscriptomics is relatively young, the number of projects related to metatranscriptome analysis increases every year and the scope of its applications expands. However, there are several problems that complicate metatranscriptome analysis: complexity of microbial communities, wide dynamic range of transcriptome expression and importantly, the lack of high-quality computational methods for assembling meta-RNA sequencing data. These factors deteriorate the contiguity and completeness of metatranscriptome assemblies, therefore affecting further downstream analysis. Here we present MetaGT, a pipeline for de novo assembly of metatranscriptomes, which is based on the idea of combining both metatranscriptomic and metagenomic data sequenced from the same sample. MetaGT assembles metatranscriptomic contigs and fills in missing regions based on their alignments to metagenome assembly. This approach allows to overcome described complexities and obtain complete RNA sequences, and additionally estimate their abundances. Using various publicly available real and simulated datasets, we demonstrate that MetaGT yields significant improvement in coverage and completeness of metatranscriptome assemblies compared to existing methods that do not exploit metagenomic data. The pipeline is implemented in NextFlow and is freely available fromhttps://github.com/ablab/metaGT.Peer reviewe
Simultaneous measurement of HbA1C and Hemoglobin by Turbidimetric inhibition immunoassay from a single punch of dried blood spot samples
7-13Hemoglobin and glycosylated hemoglobin (HbA1C) are frequently monitored health indicators in population based
studies for information about the status of nutrition and diabetes control. We present here possibly for the first time the
findings of simultaneous estimation of Hemoglobin and HbA1C on Dried blood spot (DBS) samples by a single test.
Validation was done by turbidimetric inhibition immunoassay (TINIA) using Roche Integra 400 plus instrument. Paired
whole blood and DBS samples were tested for HbA1C estimation by Integra 400 plus. Total hemoglobin values obtained
during HbA1C estimation were compared with hemoglobin values estimated by Coulter AcT 5 Diff CP Hematology
counter. Agreement in HbA1C and hemoglobin values between paired whole blood and DBS samples was found to be high
with R2 values of 0.994 and 0.9349, respectively. Intra- and inter- assay precision was found to be within 10% for both
parameters. Values obtained after assaying DBS samples prepared by spotting proficiency samples on Whatman
903 protein saver cards demonstrated acceptable standard deviation indices resulting in successful participation in
EQAS programs for both these parameters. The results reveal the potential of TINIA for simultaneous estimation of
hemoglobin and HbA1C from a single punch of the DBS samples
Education, gender, and state-level disparities in the health of older Indians: Evidence from biomarker data
AbstractUsing new biomarker data from the 2010 pilot round of the Longitudinal Aging Study in India (LASI), we investigate education, gender, and state-level disparities in health. We find that hemoglobin level, a marker for anemia, is lower for respondents with no schooling (0.7g/dL less in the adjusted model) compared to those with some formal education and is also lower for females than for males (2.0g/dL less in the adjusted model). In addition, we find that about one third of respondents in our sample aged 45 or older have high C-reaction protein (CRP) levels (>3mg/L), an indicator of inflammation and a risk factor for cardiovascular disease. We find no evidence of educational or gender differences in CRP, but there are significant state-level disparities, with Kerala residents exhibiting the lowest CRP levels (a mean of 1.96mg/L compared to 3.28mg/L in Rajasthan, the state with the highest CRP). We use the Blinder–Oaxaca decomposition approach to explain group-level differences, and find that state-level disparities in CRP are mainly due to heterogeneity in the association of the observed characteristics of respondents with CRP, rather than differences in the distribution of endowments across the sampled state populations
