RESUMO
Background: Childhood diarrhoea mainly caused by Group A Rotavirus, is a major global health issue, especially for children under five. In India, RVA-induced diarrhoea causes numerous deaths, hospitalizations, and outpatient visits annually. Vaccination is crucial in preventing RVA, with WHO-approved oral vaccines significantly reducing global mortality and morbidity. However, challenges persist in implementing vaccines in regions like sub-Saharan Africa due to factors like malnutrition and unsanitary conditions. Despite this, since 2009, low-income countries have seen a decline in RVA-related illness. Methods: Over 18 months, from January 2021 to June 2022, a study at the Post Grad Dept. of Microbiology, Index Medical College, Hospital and Research Centre in Indore, MP, involved 250 children under five with acute gastroenteritis. Ethical clearance and parental consent were obtained. Data included demographic, antenatal, diarrhoea l symptoms, feeding, hygiene, physical exams, and stool analysis. Results: 250 children under five were screened for Rotavirus. 60 tested positive, mostly in 6–12-month-olds during cooler months in urban areas. 80% were from low socioeconomic backgrounds. Exclusive breastfeeding linked to lower incidence. Vomiting and severe dehydration more frequent in positive cases. ELISA and ICG methods equally effective. Conclusions: Childhood diarrhoea, primarily caused by Rotavirus, remains a leading cause of under-five deaths, totalling 600,000 annually. Among 250 children studied, 60 tested positive for Rotavirus, especially among males aged 7-12 months, with infections peaking in cooler months. Both ELISA and ICG were equally effective in detection. Treatment primarily involves oral rehydration with low osmolarity ORS. Predominant strains were G1 P (8) and G2 P (4). Global endorsement of rotavirus vaccines like Rotarix and Rotateq, with Rotavac showing promise in India, signals progress in fighting rotavirus, potentially improving public health via inclusion in state immunization programs.
RESUMO
Minimum tillage methods offer numerous benefits compared to conventional tillage, including reduced farm operations to establish a good seedbed. Spot tillage, in particular, has advantages such as preserving soil structure, preventing erosion, saving time and energy, and reducing input costs. For this study, the effect of different auger size (40, 50 & 70mm) which was operated by 12V DC motor at different depth of operations (80, 120 & 160mm) were determined. The different parameters were measured such as bulk density, cone index, germination percentage, root length, root weight and cob weight for maize crop (GAYMH-3) and same for traditional sowing method. The results showed that auger size (40, 50 & 70mm) and depth of operation (80, 120 & 160mm) significantly influenced bulk density as bulk density of the soil increased with depth and decrease with increase in auger size. The larger auger (70mm) resulting in lower values in bulk density due to more soil removal. However, cone index was not significantly affected by auger size (40, 50 & 70mm) and depth of operation (80, 120 & 160mm). Seed germination for maize was consistently around 90%, with no significant effects of auger size and depth of operation were observed. An auger size (70mm) was associated with shorter root lengths. Increasing depth resulted in greater root development, leading to longer roots was observed in small size augers. Larger auger size and deeper depths generally resulted in higher root weights. Cob weight increased with auger size (70mm) and deeper depths. Auger size and depth significantly impacted cob weight. Overall, results showed that auger having the size of 70mm and depth of operation at 160mm was desirable compared to other auger size in terms of lower bulk density and cone index but increased root weight and cob weight of maize crop.
