A hospital-based cross-sectional study on congenital anomalies in newborn babies of Uttarakhand
Background: Congenital anomalies make an important contribution to infant mortality. They remain a leading cause of death in many countries of the world. The prevalence and pattern of presentation vary from place to place. Objective: The aims and objectives of this study were to determine the prevalence of congenital abnormalities among babies (inborn and outborn) admitted at the Himalayan Hospital, Dehradun, Uttarakhand, India. Materials and Methods: A cross-sectional retrospective study was conducted in a Medical College Hospital in Uttarakhand. The case files of these babies were retrieved from the hospital records department and examined individually by the investigators. Data collection was done with structured forms designed for the study. Result: Among total 2242 neonates included in the study, the prevalence of congenital malformations was 8.3%. Central nervous system and cardiovascular, musculoskeletal, and genitourinary systems were found to be most commonly involved. Conclusion: The present study provides us an idea regarding prevalence of cases of congenital malformations and factors affecting it. In Indian environment, this study helps us to know the pattern of congenital malformation in this part of the country
A comparative study of functional outcome of external fixation and volar plating in unstable distal radius fractures
Background: Distal radius fractures are amongst the most common injuries seen in the emergency department. It is imperative to restore the anatomy as much as possible in order to restore wrist function. Identifying a fracture as ‘unstable’ is critical in predicting the final outcome of treatment. The present study compares two primary modalities of treatment: external fixation and volar plating in terms of the functional outcome post-surgery. Aim of the study was to compare the functional outcome of fixation of unstable distal radius fractures by external fixation to that of volar plating by the Disabilities of the Arm, Shoulder and Hand (DASH) scoring system and analysis of recovery of grip strength and range of motion. Settings and design: Hospital-based; randomized control trial.Methods: 80 patients presenting with unstable distal radius fractures were randomized into two groups of 40 each. One group received external fixation and the second received open reduction with volar plate fixation as the primary intervention. DASH scores were obtained and compared at specified time intervals following surgery.Results: The results of our study show a better improvement in the mean DASH scores at 3, 6 and 12 months in the volar plating group as compared to the external fixation group.Conclusions: Volar plating, with its definitive advantage of direct fracture visualization, has an overall better functional outcome with greater postoperative wrist motion and a lower incidence of complications.
Effect of vam fungi and applied phosphorus through stcr precision model on growth, yield and nutrient dynamics in maize in acid alfisol
The Inoculation of three VAM cultures viz. local culture (Glomus mosseae), VAM culture from IARI, New Delhi (Glomus mosseae) and a culture from The Energy Research Institute (TERI), New Delhi (Glomus Intraradices) alone or with increasing applied phosphorus levels from 25 to 75% of recommended P2OS based on soil test crop response (STCR) precision model improved the plant height, shoot and root dry matter accumulation, root length and root weight density as well as yield attributes of ralnfed maize in an acid alflsol of NW Himalayas. It was revealed that sole application of any of 3 VAM fungi did not have pronounced effect on phenologlcal stages though combined application of VAM cultures with increasing P levels from 25 to 75% of recommended P2O5 reduced the days to various phenologlcal stages, it was reported that sole application of these 3 VAM cultures improved the maize grain yield by 17.10 to 25.36% over control. Increase in P levels from 25 to 75% of recommended P2O5 besides VAM inoculation resulted in consistent and significant Improvement In grain, stover and biological yield of maize. 75% of recommended P2O5 alongwith VAM cultures achieved the goal of targeted yield (40 q ha"1) of maize, thus, saving the applied P to the tune of about 25% without Impairing the soil fertility in the present stud
Ecological and Economic Potential of Major Halophytes and Salt Tolerant Vegetation in India
Soil salinization is a global and climatic phenomenon that affects various spheres of life. The present rate of salinization is perilously fast because of global climate change and associated events leading to enhanced land degradation, loss of soil fertility and crop productivity. In this chapter, we tried to focus on the arid and semiarid regions of India along with our coastal zone which are economically fragile regions and need much closer attention. In future, India will face extreme pressure on its land resources in agriculture because of likely rapid degradation of these resources. Thus, salt affected soils must be brought under cultivation by adopting site specific strategies to ensure national food and nutritional security. In this regard, a comprehensive review of the major halophytes of these ecological zones, its mechanism of salt tolerance, ecological and economic potential is done. The potential applications of saline land vegetation including halophytes in climate change mitigation, phytoremediation, desalination, food, secondary metabolite and nutraceutical production, medicine, and saline agriculture have been discussed. Further, we tried to focus on popular farmer adopted halophytic species including edible ones, their uses, products of economic significance etc. which is highly imperative for effective utilization of these saline soils leading to improved livelihood and sustenance of resource poor farmers along with improved ecological balance
Influence of Vesicular Arbuscular Mycorrhizal Fungi and Applied Phosphorus on Root Colonization in Wheat and Plant Nutrient Dynamics in a Phosphorus-Deficient Acid Alfisol of Western Himalayas
Vesicular arbuscular mycorrhizal (VAM) fungi symbiosis confers benefits directly to the host plant's growth and yield through acquisition of phosphorus and other macro- and micronutrients, especially from phosphorus (P)–deficient acidic soils. The inoculation of three VAM cultures [viz., local culture (Glomus mosseae), VAM culture from Indian Agricultural Research Institute (IARI), New Delhi (Glomus mosseae), and a culture from the Centre for Mycorrhizal Research, Energy Research Institute (TERI), New Delhi (Glomus intraradices)] along with P fertilization in wheat in a P-deficient acidic alfisol improved the root colonization by 16–24% while grain and straw yields increased by 12.6–15.7% and 13.4–15.4%, respectively, over the control. Uptake of nitrogen (N), P, potassium (K), iron (Fe), manganese (Mn), zinc (Zn), and copper (Cu) was also improved with VAM inoculation over control, but the magnitude of uptake was significantly greater only in the cases of P, Fe, Zn, and Cu. Inoculation of wheat with three VAM cultures in combination with increasing inorganic P application from 50% to 75% of the recommended P2O5 dose to wheat through the targeted yield concept following the soil-test crop response (STCR) precision model resulted in consistent and significant improvement in grain and straw yield, macronutrient (NPK) uptake, and micronutrient (Fe, Mn, Zn, Cu) uptake in wheat though root colonization did not improve at P2O5 doses beyond 50% of the recommended dose. The VAM cultures alone or in combination with increasing P levels from 50% to 75% P2O5 dose resulted in reduction of diethylenetriaminepentaacetic acid (DTPA)–extractable micronutrient (Fe, Mn, Zn, Cu) contents in P-deficient acidic soil over the control and initial fertility status, although micronutrient contents were relatively greater in VAM-supplied plots alone or in combination with 50% to 75% P2O5 dose over sole application of 100% P2O5 dose, thereby indicating the positive role of VAM in nutrient mobilization and nutrient dynamics in the soil–plant system. There was significant improvement in available N and P status in soil with VAM inoculation coupled with increasing P levels upto 75% P2O5 dose, although the greatest P buildup was obtained with sole application of 100% P2O5 dose. The TERI VAM culture (Glomus intraradices) showed its superiority over the other two cultures (Glomus mosseae) in terms of crop yield and nutrient uptake in wheat though the differences were nonsignificant among the VAM cultures alone or at each P level. Overall, it was inferred that use of VA-mycorrhizal fungi is beneficial under low soil P or in low input (nutrient)–intensive agroecosystems
Improving Phosphorus Use through Co-inoculation of Vesicular Arbuscular Mycorrhizal Fungi and Phosphate-Solubilizing Bacteria in Maize in an Acidic Alfisol
Performance of three vesicular arbuscular mycorrhizal (VAM) fungi cultures and a phosphate-solubilizing bacteria (PSB) culture alone or in combination with or without 75% of the recommended P2O5 dose based on soil-test crop response model was examined in maize in a phosphorus (P)-deficient acidic Alfisol in a glasshouse pot experiment. Sole application of VAM besides co-inoculation with PSB (Pseudomonas striata) and inorganic P stimulated mycorrhizal root colonization. Sole application of PSB, VAMT (Glomus intraradices), and VAMI (Glomus mosseae) as well as co-inoculation of VAM with PSB significantly improved crop productivity besides grain protein content, thus indicating a synergistic interaction between VAM and PSB. Application of VAMT or VAMI + PSB + 75% P2O5 remained at par with sole application of 100% P2O5 dose with regard to productivity, nutrient uptake, and soil fertility status (particularly P), thus indicating economization of fertilizer P to the tune of about 25% without compromising crop productivity and soil fertility in an acidic Alfisol
Nitrogen Use Efficiency in Sorghum: Exploring Native Variability for Traits Under Variable N-Regimes
Exploring the natural genetic variability and its exploitation for improved Nitrogen
Use Efficiency (NUE) in sorghum is one of the primary goals in the modern crop
improvement programs. The integrated strategies include high-throughput phenotyping,
next generation sequencing (NGS)-based genotyping technologies, and a priori selected
candidate gene studies that help understand the detailed physiological and molecular
mechanisms underpinning this complex trait. A set of sixty diverse sorghum genotypes
was evaluated for different vegetative, reproductive, and yield traits related to NUE in
the field (under three N regimes) for two seasons. Significant variations for different
yield and related traits under 0 and 50% N confirmed the availability of native
genetic variability in sorghum under low N regimes. Sorghum genotypes with distinct
genetic background had interestingly similar NUE associated traits. The Genotyping-
By-Sequencing based SNPs (>89 K) were used to study the population structure,
and phylogenetic groupings identified three distinct groups. The information of grain N
and stalk N content of the individuals covered on the phylogenetic groups indicated
randomness in the distribution for adaptation under variable N regimes. This study
identified promising sorghum genotypes with consistent performance under varying
environments, with buffer capacity for yield under low N conditions. We also report
better performing genotypes for varied production use—grain, stover, and dual-purpose
sorghum having differential adaptation response to NUE traits. Expression profiling
of NUE associated genes in shoot and root tissues of contrasting lines (PVK801
and HDW703) grown in varying N conditions revealed interesting outcomes. Root
tissues of contrasting lines exhibited differential expression profiles for transporter genes
[ammonium transporter (SbAMT), nitrate transporters (SbNRT)]; primary assimilatory
(glutamine synthetase (SbGS), glutamate synthase (SbGOGAT[NADH], SbGOGAT[Fd]),
assimilatory genes [nitrite reductase (SbNiR[NADH]3)]; and amino acid biosynthesis
associated gene [glutamate dehydrogenase (SbGDH)]. Identification and expression profiling of contrasting sorghum genotypes in varying N dosages will provide new
information to understand the response of NUE genes toward adaptation to the
differential N regimes in sorghum. High NUE genotypes identified from this study could
be potential candidates for in-depth molecular analysis and contribute toward the
development of N efficient sorghum cultivars
Genome-wide identification and characterization of Puccinia striiformis-responsive lncRNAs in Triticum aestivum
Wheat stripe rust (yellow rust) caused by Puccinia striiformis f. sp. tritici (Pst) is a serious biotic stress factor limiting wheat production worldwide. Emerging evidence demonstrates that long non-coding RNAs (lncRNAs) participate in various developmental processes in plants via post-transcription regulation. In this study, RNA sequencing (RNA-seq) was performed on a pair of near-isogenic lines—rust resistance line FLW29 and rust susceptible line PBW343—which differed only in the rust susceptibility trait. A total of 6,807 lncRNA transcripts were identified using bioinformatics analyses, among which 10 lncRNAs were found to be differentially expressed between resistance and susceptible lines. In order to find the target genes of the identified lncRNAs, their interactions with wheat microRNA (miRNAs) were predicted. A total of 199 lncRNAs showed interactions with 65 miRNAs, which further target 757 distinct mRNA transcripts. Moreover, detailed functional annotations of the target genes were used to identify the candidate genes, pathways, domains, families, and transcription factors that may be related to stripe rust resistance response in wheat plants. The NAC domain protein, disease resistance proteins RPP13 and RPM1, At1g58400, monodehydroascorbate reductase, NBS-LRR-like protein, rust resistance kinase Lr10-like, LRR receptor, serine/threonine-protein kinase, and cysteine proteinase are among the identified targets that are crucial for wheat stripe rust resistance. Semiquantitative PCR analysis of some of the differentially expressed lncRNAs revealed variations in expression profiles of two lncRNAs between the Pst-resistant and Pst-susceptible genotypes at least under one condition. Additionally, simple sequence repeats (SSRs) were also identified from wheat lncRNA sequences, which may be very useful for conducting targeted gene mapping studies of stripe rust resistance in wheat. These findings improved our understanding of the molecular mechanism responsible for the stripe rust disease that can be further utilized to develop wheat varieties with durable resistance to this disease
Mapping of variations in child stunting, wasting and underweight within the states of India: the Global Burden of Disease Study 2000–2017
Background
To inform actions at the district level under the National Nutrition Mission (NNM), we assessed the prevalence trends of child growth failure (CGF) indicators for all districts in India and inequality between districts within the states.
Methods
We assessed the trends of CGF indicators (stunting, wasting and underweight) from 2000 to 2017 across the districts of India, aggregated from 5 × 5 km grid estimates, using all accessible data from various surveys with subnational geographical information. The states were categorised into three groups using their Socio-demographic Index (SDI) levels calculated as part of the Global Burden of Disease Study based on per capita income, mean education and fertility rate in women younger than 25 years. Inequality between districts within the states was assessed using coefficient of variation (CV). We projected the prevalence of CGF indicators for the districts up to 2030 based on the trends from 2000 to 2017 to compare with the NNM 2022 targets for stunting and underweight, and the WHO/UNICEF 2030 targets for stunting and wasting. We assessed Pearson correlation coefficient between two major national surveys for district-level estimates of CGF indicators in the states.
Findings
The prevalence of stunting ranged 3.8-fold from 16.4% (95% UI 15.2–17.8) to 62.8% (95% UI 61.5–64.0) among the 723 districts of India in 2017, wasting ranged 5.4-fold from 5.5% (95% UI 5.1–6.1) to 30.0% (95% UI 28.2–31.8), and underweight ranged 4.6-fold from 11.0% (95% UI 10.5–11.9) to 51.0% (95% UI 49.9–52.1). 36.1% of the districts in India had stunting prevalence 40% or more, with 67.0% districts in the low SDI states group and only 1.1% districts in the high SDI states with this level of stunting. The prevalence of stunting declined significantly from 2010 to 2017 in 98.5% of the districts with a maximum decline of 41.2% (95% UI 40.3–42.5), wasting in 61.3% with a maximum decline of 44.0% (95% UI 42.3–46.7), and underweight in 95.0% with a maximum decline of 53.9% (95% UI 52.8–55.4). The CV varied 7.4-fold for stunting, 12.2-fold for wasting, and 8.6-fold for underweight between the states in 2017; the CV increased for stunting in 28 out of 31 states, for wasting in 16 states, and for underweight in 20 states from 2000 to 2017. In order to reach the NNM 2022 targets for stunting and underweight individually, 82.6% and 98.5% of the districts in India would need a rate of improvement higher than they had up to 2017, respectively. To achieve the WHO/UNICEF 2030 target for wasting, all districts in India would need a rate of improvement higher than they had up to 2017. The correlation between the two national surveys for district-level estimates was poor, with Pearson correlation coefficient of 0.7 only in Odisha and four small north-eastern states out of the 27 states covered by these surveys.
Interpretation
CGF indicators have improved in India, but there are substantial variations between the districts in their magnitude and rate of decline, and the inequality between districts has increased in a large proportion of the states. The poor correlation between the national surveys for CGF estimates highlights the need to standardise collection of anthropometric data in India. The district-level trends in this report provide a useful reference for targeting the efforts under NNM to reduce CGF across India and meet the Indian and global targets.
