An Early Childhood Care and Education (ECCE) program in rural India was evaluated in terms of care and learning outcomes of children. The study was undertaken to observe and describe the ECCE system for children who were economically and educationally disadvantaged and enrolled in three Government Primary Schools (GPS) in India. In particular, the study tries to answer the question, ‘What factors affect the learning of Mathematics and English in the primary schools of rural Tamil Nadu?’ This Observational study was undertaken over a six-month period. The study included 183 children from LKG to Class 3 in normative stages of development as per their age and stage requirements. The parameters that were observed included learning outcomes in Math, English, Science and Social studies. An innovative daily baseline assessment was undertaken over a three-month period to understand children’s learning milestones. Results indicate that the learning outcomes were deplorably poor by Indian and international standards of education. Many challenges still remain in helping children gain a healthy start to life. There is a lack of an integrated framework that combines both health & well-being and learning. In the COVID-19 pandemic era, it is critical to move away from the traditional physical center models to a more hybrid scientific and technology driven systems for scale that are financially viable. These require a planned approach for introduction considering the scale in which it has to be implemented in India. Such plans need to be both top-down and bottom-up approach which entail large up-front investment in communicating and educating all the stakeholders. Personalized attention is not possible in traditional systems catering to such a large population. Additionally, and more importantly, there are no early warning mechanisms in place to help identify issues when it matters the most. Our analysis supports our research question and proves our hypotheses.

Background/Aims Consensus guidelines for performance and analysis of high-resolution esophageal manometry (HREM) recommend use of equipment, population and posture specific normative values. To provide normative values for Chicago classification (CC) metrics in the physiological seated position for a 16-channel water perfused system (Dentsleeve HREM catheter, Advanced Manometry Systems, Melbourne, Australia) widely used in India and other countries with limited access to solid-state equipment. The results are compared with published CC metrics in supine position done using the same system and volunteers. Methods HREM tracings of ten 5 mL water swallows in sitting posture were acquired in healthy volunteers and normative values for CC version 3.0 metrics calculated. Individual swallows were paired with previously reported supine swallows for postural variations (Wilcoxon sign rank test) and concordance of CC diagnoses (Pearson coefficient). Results Analysis of 530 sitting posture water swallows (53 subjects) and comparison with their supine data revealed significantly higher integrated relaxation pressure (IRP; median 6.7 mmHg vs 6.1 mmHg) but lower distal latency (DL; mean 6.3 seconds vs 6.8 seconds) and distal contractile integral (DCI; mean 1224 mmHg·sec·cm vs 1456 mmHg·sec·cm). Sitting posture normal was defined as: IRP < 13.9, DL > 4.5, and DCI = 115-4500 (absent contractility: DCI < 30). CC diagnoses concordance using posture-specific cut-offs was moderate (k = 0.47). Conclusions This paper provides normative values for the Advanced Manometry Systems 16-channel water perfused system in the physiological seated position for CC metrics. Our findings of higher IRP and lower DCI in sitting posture than previously reported supine CC cut-offs, confirm the need to use posture-specific cut-offs for reporting HREM tracings.

We investigated the effect of Silver nanoparticles (AgNPs) on the gut protease activity of insecticide resistant gram caterpillar, Helicoverpa armigera. The leaf extracts of Peepal tree, Ficus religiosa (FR) and banyan tree, Ficus benghalensis (FB) mediated biogenic AgNPs were synthesized to modulate the function of gut protease activity in H. armigera (Ha). Bioassay with FR and FB AgNPs significantly reduced both larval weight and survival rate of H. armigera. The FR and FB AgNPs inhibited the Ha-Gut protease activity by 50 and 70% at 100 μg concentration respectively. The FR and FB Silver nanoparticles were interacted and binds with high affinity with protease. The inhibition studies on Ha-gut protease activity may contribute towards developing new IRM(Insecticide Resistant Management) strategies against H. armigera to overcome insecticidal resistance issues.
