    Multi-Res-Attention UNet: A CNN Model for the Segmentation of Focal Cortical Dysplasia Lesions from Magnetic Resonance Images
    (Institute of Electrical and Electronics Engineers Inc., 2021) Thomas, E.; Pawan, S.J.; Kumar, S.; Horo, A.; Niyas, S.; Vinayagamani, S.; Kesavadas, C.; Rajan, J.
    In this work, we have focused on the segmentation of Focal Cortical Dysplasia (FCD) regions from MRI images. FCD is a congenital malformation of brain development that is considered as the most common causative of intractable epilepsy in adults and children. To our knowledge, the latest work concerning the automatic segmentation of FCD was proposed using a fully convolutional neural network (FCN) model based on UNet. While there is no doubt that the model outperformed conventional image processing techniques by a considerable margin, it suffers from several pitfalls. First, it does not account for the large semantic gap of feature maps passed from the encoder to the decoder layer through the long skip connections. Second, it fails to leverage the salient features that represent complex FCD lesions and suppress most of the irrelevant features in the input sample. We propose Multi-Res-Attention UNet; a novel hybrid skip connection-based FCN architecture that addresses these drawbacks. Moreover, we have trained it from scratch for the detection of FCD from 3 T MRI 3D FLAIR images and conducted 5-fold cross-validation to evaluate the model. FCD detection rate (Recall) of 92% was achieved for patient wise analysis. © 2013 IEEE.

    Trends in Selected Birth Defects among Parents from Below Poverty Line Population in Karnataka during 2010-2020
    (Wolters Kluwer Medknow Publications, 2022) Nanjunda, D.C.; Jyothi Lakshmi, S.; Rajesh Acharya, R.H.; Mishra, A.K.
    The aim of the study is to reveal the common birth defects among parents of newborns belonging to the below poverty line (BPL) category in Karnataka state (South India) by analyzing Suvarna Arogya Suraksha Trust data. In the last 10 years, 3672 kids in BPL families have been born with various birth abnormalities. It is found that 50.3% of newborns have anorectal malformations, 33.1% have hypospadias, 6.0% have diaphragmatic hernia, 5.1% have esophageal atresia, and 2.8% have intestinal atresia and obstruct. As a parent's age rises, the likelihood of having a child with birth abnormalities raise as well, particularly anorectal malformations than diaphragmatic hernia. Male newborns have a higher risk of birth defects. We hypothesized that poverty, material deprivation, and low socioeconomic profile throughout the life course among the BPL community could be some of the key reasons for poor maternal health care and related neonatal outcomes. © 2022 Indian Journal of Public Health | Published by Wolters Kluwer-Medknow.
