Identification and genetic diversity analysis of high-yielding charcoal rot resistant soybean genotypes.

Charcoal rot disease caused by Macrophomina phaseolina (Tassi) Goid is one of the most devastating diseases in soybean in India. During 2018, 226 diverse soybean genotypes were evaluated for genetic resistance under hot-spot conditions. Out of them, a subset of 151 genotypes were selected based on Percent Disease Incidence (PDI) and better agronomic performance. Out of these 151 genotypes evaluated during 2019, 43 genotypes were selected based on PDI and superior agronomic performance for further field evaluation and molecular characterization. During 2020 and 2021, these forty-three genotypes, were evaluated for PDI, Area Under Disease Progress Curve (AUDPC), and grain yield. In 2020, genotype JS 20-20 showed least PDI (0.42) and AUDPC (9.37).Highest grain yield was recorded by the genotype JS 21-05 (515.00 g). In 2021, genotype JS 20-20 exhibited least PDI (0.00) and AUDPC (0.00).Highest grain yield was recorded in JS 20-98 (631.66 g). Across both years, JS 20-20 had the least PDI (0.21) and AUDPC (4.68), while grain yield was highest in JS 20-98 (571.67 g). Through MGIDI (multi-trait genotype-ideotype distance) analysis, JS 21-05 (G19), JS 22-01 (G43), JS 20-98 (G28) and JS 20-20 (G21) were identified as the ideotypes with respect to the traits that were evaluated. Two unique alleles, Satt588 (100 bp) on linkage group K (Chromosome no 9) and Sat_218 (200 bp) on linkage group H (Chromosome no 12), were specific for thetwo resistant genotypes JS 21-71and DS 1318, respectively. Through cluster analysis, it was observed that the genotypes bred at Jabalpur were more genetically related.

Hearing outcomes of cochlear implant recipients with pre-operatively identified cochlear dead regions.

Objectives: To determine how patients who did not meet UK TA166 NICE criteria for cochlear implantation (CI) but were subsequently found to have cochlear dead regions (DRs) performed with CI.Methods: A retrospective review of medical records was performed on CI recipients: 152 controls and 40 in the DR group. Of these, 34 pairs were matched by pre-operative Bamford-Kowal-Bench (BKB) scores and compared.Results: The forty DR patients had a median age at implantation of 56 years. Their mean pre-operative BKB score of 23% increased to 78% after CI. Thirty-seven experienced improvements in BKB scores. In matched case-control analysis, the improvement in mean BKB score with CI was no different (p = 0.19) between the DR group and control group; a similar proportion of patients benefitted in each group.Discussion: This study is the largestreport to date of performance of patients with DRs, before and after CI. The DR group gain similar benefit as the controls.Conclusion: Patients with DRs, who did not meet TA166 NICE criteria, received the same benefit as those who did. TEN testing to detect DRs should be included in routine CI work-up where standard criteria are not met.

Clinico-epidemiological study of low birth weight newborns in the Eastern part of Nepal.

Low birth weight (LBW) remains an important cause of newborn morbidity and mortality. A hospital based prospective and descriptive study was conducted at Paediatric wards, Nursery, Neonatal intensive unit (NICU) and Post natal ward during period of June to October 2010 to note the clinico-epidemiological profile of Low Birth Weight (LBW) newborns. Incidence of the LBW babies in our hospital was 14.45%; more than four fifth (82.2%) baby's mothers were primigravida. Eighty two percent mothers had unbooked pregnancies. Twenty and half percent LBW babies were twins. The mean duration of hospital stay of the subject was 7.4 (± 5.5) days. The mean birth weight of LBW babies was 1648 (± 344) grams. Clinical sepsis, non physiological jaundice and hypoglycaemia were the three most common complications of LBW babies. Antibiotics, oxygen and phototherapy were the three commonest modes of therapy. Majority of children (82.0%) improved and were discharged. Birth weight and gestational age were significantly different between survivors and babies who expired. Primigravida and lesser antenatal visits were important risk factors for Low birth weight babies. Birth weight, gestational age, apnoea and mechanical ventilation were the predictors of outcome.

Oral zinc supplementation for reducing mortality in probable neonatal sepsis: a double blind randomized placebo controlled trial.

OBJECTIVE: To study the role of Zinc in the treatment of neonatal sepsis. DESIGN: Double blind, randomized, placebo controlled trial. SETTING: Tertiary Care Hospital. PARTICIPANTS: 614 neonates with probable neonatal sepsis. INTERVENTION: The drug group (n=307) received 1mg/kg/day of elemental zinc, and placebo group (n=307) received the placebo, in addition to antibiotic therapy and supportive care, till the final outcome (discharge/death). OUTCOME MEASURES: Decrease in mortality rates (primary outcome), duration of hospital stay and need of higher lines of antibiotic therapy (secondary outcomes) were tested. RESULTS: Baseline characteristics of the two groups were similar. No statistically significant differences between drug and placebo group were found in mortality rate (9.77% vs 7.81%; P=0.393), mean duration of hospital stay (142.85 ± 69.41 hrs, vs. 147.99 ± 73.13 hrs; P=0.841), and requirement of higher lines of antibiotic therapy (13.35% vs 12.05%, P=0.628) after supplementation. CONCLUSIONS: This study does not report decrease in mortality rates, duration of hospital stay and requirement of higher lines of antibiotic therapy following zinc supplementation in neonatal sepsis.

Clinical profile and outcome of children presenting with poisoning or intoxication: a hospital based study.

Poisoning is a common preventable cause of morbidity and mortality in children. Most of the poisoning in children less than 5 years of age is accidental. Objective of the study was to study the clinical profile and outcome of childhood poisoning and intoxication. This was a retrospective study done in patients who were admitted in pediatric wards and pediatric intensive care unit (PICU) of BP Koirala Institute of Health Sciences with history of ingestion of poison or intoxication or envenomation firom January 2005 to June 2008. The data collected were analyzed with SPSS 12.0 software. There were 122 children enrolled in study. Male: female ratio was 1.4:1. The mean age of presentation was 5.8 years. Among 122 patients, 43.4% received pre-referral treatment in the form of gastric lavage, atropine etc. Organophosphorus poisoning was the commonest poisoning seen in 55 (45.1%) patients followed by hydrocarbon 12 (9.8%), mushroom 10 (8.2%) and organochlorine 10 (8.2%) poisoning. During treatment, 50.0% received antidotes. 55.7% received antibiotics, gastric lavage and anticonvulsants were required in 43.4% and 13.9% respectively. Overall survival was 87.4%. The time interval between intoxication and presentation to hospital, mean Glasgow Coma Scale (GCS) and presence of coma (GCS <8) were significantly different between survivors and expired cases. In conclusion, organophosphorus is the commonest agent involved in childhood poisoning. Overall, the outcome is good with 87.4% survival in our hospital. The time gap between the poisoning and presentation to hospital and presence of coma predict mortality.
