Systemic lidocaine versus ultrasound-guided transversus abdominis plane block for postoperative analgesia: A comparative randomised study in bariatric surgical patients.

BACKGROUND AND AIMS: The multimodal analgesia strategies to minimise opioid-related side effects are highly desirable in bariatric surgical procedures. We evaluated the efficacy of ultrasound-guided transversus abdominis plane (USG-TAP) block and intravenous lidocaine for postoperative analgesia in obese patients undergoing laparoscopic bariatric surgery. METHODS: We studied 56 patients with body mass index >35 kg/m2. They were randomly allocated to Lidocaine group (Group A) and USG-TAP group (Group B). Group A patients were given intravenous Lidocaine (1.5 mg/kg) bolus followed by (1.5 mg/kg/h) infusion. Group B patients were given ultrasound-guided bilateral TAP block using 20 cc of 0.375% ropivacaine each side. Postoperative numeric rating pain scale score (NRS) hours were compared. Other parameters compared were total fentanyl requirement, sedation score, postoperative nausea vomiting (PONV) score and patient satisfaction score. A P value < 0.05 was considered statistically significant. RESULTS: The patient in the Group A had lower resting NRS score (P < 0.05) postoperatively and less fentanyl consumption (P < 0.001) than in Group B. The difference in the sedation scores (P = 0.161) and PONV (P = 0.293) score was found to be statistically insignificant between Group A and B. The difference between the two groups was statistically significant with respect to patient satisfaction score with majority of patients having an excellent patient satisfaction score in Group A as compared to Group B. CONCLUSION: Intravenous Lidocaine as part of multimodal analgesic technique in obese patients undergoing laparoscopic bariatric surgery improves pain score and reduces opioid requirement as compared to USG-TAP Block.

Household Food Insecurity and Mental Health Among Teenage Girls Living in Urban Slums in Varanasi, India: A Cross-Sectional Study.

This study was undertaken to investigate the relation between household food insecurity and mental health problems in teenage girls living in urban slums. This community-based cross-sectional study was conducted in 5 urban slums in Varanasi, India, between September 2016 and July 2017. A probability proportion to size (PPS) method was employed to select 5 of 210 urban slums at a first stage, and in the second stage, 418 teenage girls were chosen randomly from selected households. The Household Food Insecurity Access Scale (HFIAS) and mental health inventory tools were employed to assess food insecurity and mental health status. Multivariable logistic regression analysis with at a 95% confidence interval (CI) was used to assess the association between household food insecurity and mental health status. Of 418 respondents, 47.6% were food insecure; 64.1%, 57.7%, and 58.4% had high levels of anxiety, depression, or psychological distress, respectively; and 57.2% exhibited a medium level of loss of behavioral control. Furthermore, teenage girls from food insecure households were more likely to have high levels of anxiety, depression, loss of behavioral control and psychological distress than those living in food secure households. This study shows food insecurity is independently associated with mental health problems among teenage girls. Food insecurity in Indian slums should be addressed by specific public health intervention programs that provide access to sufficient safe, nutritious food.

'MATRI-SUMAN' a capacity building and text messaging intervention to enhance maternal and child health service utilization among pregnant women from rural Nepal: study protocol for a cluster randomised controlled trial.

BACKGROUND: Capacity development of health volunteers and text messaging to pregnant women through mobile phones have shown improved maternal and child health (MCH) outcomes and is associated with increased utilisation of MCH services. However, such interventions are uncommon in Nepal. We aim to carry out an intervention with the hypothesis that capacity building and text messaging intervention will increase the MCH service utilisation. METHOD/DESIGN: MATRI-SUMAN is a 12-month cluster randomized controlled trial (RCT). The trial involves pregnant women from 52 clusters of six village development committees (VDCs) covering 66,000 populations of Dhanusha district of Nepal. In the intervention clusters, Female Community Health Volunteers (FCHVs) will receive capacity development skills through reinforcement training, supervision and monitoring skills for the promotion of health seeking behaviour among pregnant women and study participants will receive periodic promotional text messaging service about MCH components through mobile phones. A sample of 354with equal numbers in each study arm is estimated using power calculation formula. The primary outcomes of this study are the rate of utilization of skilled birth attendants and consumption of a specified diversified meal. The secondary outcomes are: four antenatal (ANC) visits, weight gain of women during pregnancy, delivery of a baby at the health facility, postnatal care (PNC) visits, positive changes in child feeding practices among mothers, performance of FCHVs in MCH service utilization. DISCUSSION: The intervention is designed to enhance the capacity of health volunteers for the promotion of health seeking behaviour among pregnant women and text messaging through a mobile phone to expecting mothers to increase MCH service utilization. The trial if proven effective will have policy implications in poor resource settings. TRIAL REGISTRATION: ISRCTN60684155, ( https://doi.org/10.1186/ISRCTN60684155 ). The trial was registered retrospectively.

Efficacy of Ayurvedic drugs as compared to chlorhexidine in management of chronic periodontitis: A randomized controlled clinical study.

BACKGROUND: In India, Ayurveda is considered to be more effective and cheaper than modern medicine. Ayurvedic literature shows its use in treating oral diseases also. However, their effectiveness, in comparison with the allopathic mode of management, has not been assessed previously. The aim of this randomized controlled clinical trial was to compare the efficacy of ayurvedic drugs over chlorhexidine in treating chronic periodontitis. MATERIALS AND METHODS: Four hundred and eight participants, in the age group 20-49 years, suffering from mild-to-moderate chronic periodontitis were included in this study. Community periodontal index for treatment needs (CPITN) score was recorded, and oral prophylaxis was done for each patient. They were then randomly divided into 6 groups: control group (I), chlorhexidine (II), Khadiradi vati (III), Dashansanskar churana (IV), Neem (V), and Apamarga (VI); based on the drugs used by patients for the maintenance of oral hygiene after oral prophylaxis. Patients were recalled at 1 week, 1 month, and 3 months after oral prophylaxis. CPITN score was re-recorded for each patient at each follow-up. Reduction in CPITN score indicated improvement in the periodontal health. Observations were statistically analyzed using univariate ANOVA and P value was set at <0.5. RESULTS: Improvement in CPITN scores in 6 groups was as follows: I - 42.0%, II - 76.37%, III - 82.03%, IV - 83.46%, V - 78.8%, and VI - 29.9%. Higher mean percentage improvement was seen when patients used these drugs for 3 months as compared to 1 month. CONCLUSION: Dashansanskar churana and Khadiradi vati showed better results than chlorhexidine and were found to be superior in managing mild-to-moderate cases of chronic periodontitis.

Fish Karyome version 2.1: a chromosome database of fishes and other aquatic organisms.

A voluminous information is available on karyological studies of fishes; however, limited efforts were made for compilation and curation of the available karyological data in a digital form. 'Fish Karyome' database was the preliminary attempt to compile and digitize the available karyological information on finfishes belonging to the Indian subcontinent. But the database had limitations since it covered data only on Indian finfishes with limited search options. Perceiving the feedbacks from the users and its utility in fish cytogenetic studies, the Fish Karyome database was upgraded by applying Linux, Apache, MySQL and PHP (pre hypertext processor) (LAMP) technologies. In the present version, the scope of the system was increased by compiling and curating the available chromosomal information over the globe on fishes and other aquatic organisms, such as echinoderms, molluscs and arthropods, especially of aquaculture importance. Thus, Fish Karyome version 2.1 presently covers 866 chromosomal records for 726 species supported with 253 published articles and the information is being updated regularly. The database provides information on chromosome number and morphology, sex chromosomes, chromosome banding, molecular cytogenetic markers, etc. supported by fish and karyotype images through interactive tools. It also enables the users to browse and view chromosomal information based on habitat, family, conservation status and chromosome number. The system also displays chromosome number in model organisms, protocol for chromosome preparation and allied techniques and glossary of cytogenetic terms. A data submission facility has also been provided through data submission panel. The database can serve as a unique and useful resource for cytogenetic characterization, sex determination, chromosomal mapping, cytotaxonomy, karyo-evolution and systematics of fishes.

FMiR: A Curated Resource of Mitochondrial DNA Information for Fish.

Mitochondrial genome sequences have been widely used for evolutionary and phylogenetic studies. Among vertebrates, fish are an important, diverse group, and their mitogenome sequences are growing rapidly in public repositories. To facilitate mitochondrial genome analysis and to explore the valuable genetic information, we developed the Fish Mitogenome Resource (FMiR) database to provide a workbench for mitogenome annotation, species identification and microsatellite marker mining. The microsatellites are also known as simple sequence repeats (SSRs) and used as molecular markers in studies on population genetics, gene duplication and marker assisted selection. Here, easy-to-use tools have been implemented for mining SSRs and for designing primers to identify species/habitat specific markers. In addition, FMiR can analyze complete or partial mitochondrial genome sequence to identify species and to deduce relational distances among sequences across species. The database presently contains curated mitochondrial genomes from 1302 fish species belonging to 297 families and 47 orders reported from saltwater and freshwater ecosystems. In addition, the database covers information on fish species such as conservation status, ecosystem, family, distribution and occurrence downloaded from the FishBase and IUCN Red List databases. Those fish information have been used to browse mitogenome information for the species belonging to a particular category. The database is scalable in terms of content and inclusion of other analytical modules. The FMiR is running under Linux operating platform on high performance server accessible at URL http://mail.nbfgr.res.in/fmir.

In silico analysis of SSRs in mitochondrial genomes of fishes.

The availability of fish mitochondrial (mt) genomes provides an opportunity to explore the simple sequence repeats. In the present study, mt genomes of 85 fish species reported from Indian subcontinent were downloaded from NCBI and computationally analysed for finding SSRs types, frequency of occurrence, mutation and evolutionary adaptation across species. A total of 92 microsatellites in different nucleotide combinations were detected in 59 species. 26 interspersed SSRs, mostly poly (AT)n were found in the D-loop regions in the species of Cyprinidae. Fifty-six SSRs of 12 bp fixed length were observed in eight genes only. Further, identical repeat motifs were found on the same location in ATP6 and ND4 genes, which were biased towards particular habitat. The comparison of ATP6 and ND4 gene sets to other homologous sequences showed point mutations. This study explores the SSRs discovery and their utility as marker for species and population identification.

Risk factors for visceral leishmaniasis and asymptomatic Leishmania donovani infection in India and Nepal.

There is increasing interest in the role of asymptomatic infection in transmission of Visceral Leishmaniasis (VL). We studied the individual, household and environmental factors associated with asymptomatic Leishmania donovani infected individuals and VL. 7,538 individuals living in VL endemic villages in India and Nepal were divided into three mutually exclusive groups based on their VL history and Direct Agglutination Test (DAT) results in yearly serosurveys over a two-year period. The groups were (1) VL cases, (2) asymptomatically infected individuals (seroconverters) and (3) seronegative individuals. VL cases and seroconverters were compared to seronegative individuals in mixed logistic regression models. The risk of seroconversion and disease was significantly increased in individuals aged 14 to 24 years old and by the presence of other DAT-positive, asymptomatically infected individuals and VL cases in the house. The risk of seroconversion was higher in Indian than in Nepalese villages and it increased significantly with age, but not so for VL. This study demonstrates that, when risk factors for leishmanial infection and VL disease are evaluated in the same population, epidemiological determinants for asymptomatic infection and VL are largely similar.

FishMicrosat: a microsatellite database of commercially important fishes and shellfishes of the Indian subcontinent.

BACKGROUND: Microsatellite DNA is one of many powerful genetic markers used for the construction of genetic linkage maps and the study of population genetics. The biological databases in public domain hold vast numbers of microsatellite sequences for many organisms including fishes. The microsatellite data available in these data sources were extracted and managed into a database that facilitates sequences analysis and browsing relevant information. The system also helps to design primer sequences for flanking regions of repeat loci for PCR identification of polymorphism within populations. DESCRIPTION: FishMicrosat is a database of microsatellite sequences of fishes and shellfishes that includes important aquaculture species such as Lates calcarifer, Ctenopharyngodon idella, Hypophthalmichthys molitrix, Penaeus monodon, Labeo rohita, Oreochromis niloticus, Fenneropenaeus indicus and Macrobrachium rosenbergii. The database contains 4398 microsatellite sequences of 41 species belonging to 15 families from the Indian subcontinent. GenBank of NCBI was used as a prime data source for developing the database. The database presents information about simple and compound microsatellites, their clusters and locus orientation within sequences. The database has been integrated with different tools in a web interface such as primer designing, locus finding, mapping repeats, detecting similarities among sequences across species, and searching using motifs and keywords. In addition, the database has the ability to browse information on the top 10 families and the top 10 species, through record overview. CONCLUSIONS: FishMicrosat database is a useful resource for fish and shellfish microsatellite analyses and locus identification across species, which has important applications in population genetics, evolutionary studies and genetic relatedness among species. The database can be expanded further to include the microsatellite data of fishes and shellfishes from other regions and available information on genome sequencing project of species of aquaculture importance.

Biodiversity of freshwater fish of a protected river in India: comparison with unprotected habitat.

In India, freshwater environments are experiencing serious threats to biodiversity, and there is an urgent priority for the search of alternative techniques to promote fish biodiversity conservation and management. With this aim, the present study was undertaken to assess the fish biodiversity within and outside a river protected area, and to evaluate whether the protected river area provides some benefits to riverine fish biodiversity. To assess this, the pattern of freshwater fish diversity was studied in river Gerua, along with some physicochemical conditions, from April 2000 to March 2004. For this, a comparison was made between a 15km stretch of a protected area (Katerniaghat Wildlife Sanctuary), and an unprotected one 85km downstream. In each site some physicochemical conditions were obtained, and fish were caught by normal gears and the diversity per site described. Our results showed that water temperature resulted warmest during the pre-monsoon season (25 degreeC) and low during the winter (14-15 degreeC); turbidity considerably varied by season. In the protected area, a total of 87 species belonging to eight orders, 22 families and 52 genera were collected; while a maximum of 59 species belonging to six orders, 20 families and 42 genera were recorded from the unprotected areas. Cyprinids were found to be the most dominant genera and Salmostoma bacaila was the most numerous species in the sanctuary area. Other numerous species were Eutropiichthys vacha, Notopterus notopterus, Clupisoma garua and Bagarius bagarius. The results indicated more species, greater abundances, larger individuals, and higher number of endangered fishes within the sanctuary area when compared to the unprotected area. Analysis on the mean abundance of endangered and vulnerable species for the evaluated areas in the sanctuary versus unprotected ones indicated significant differences in fish abundance (p<0.05). These results showed that this riverine protected area could be important for conservation and management of fish diversity in the region, especially for resident and threatened species.

Interaction between shrimp and white spot syndrome virus through PmRab7-VP28 complex: an insight using simulation and docking studies.

White spot disease is a devastating disease of shrimp Penaeus monodon in which the shrimp receptor protein PmRab7 interacts with viral envelop protein VP28 to form PmRab7-VP28 complex, which causes initiation of the disease. The molecular mechanism implicated in the disease, the dynamic behavior of proteins as well as interaction between both the biological counterparts that crafts a micro-environment feasible for entry of virus into the shrimp is still unknown. In the present study, we applied molecular modeling (MM), molecular dynamics (MD) and docking to compute surface mapping of infective amino acid residues between interacting proteins. Our result showed that α-helix of PmRab7 (encompassing Ser74, Ile143, Thr184, Arg53, Asn144, Thr184, Arg53, Arg79) interacts with ß-sheets of VP28 (containing Ser74, Ile143, Thr184, Arg53, Asn144, Thr184, Arg53, Arg79) and Arg69-Ser74, Val75-Ile143, Leu73-Ile143, Arg79-Asn144, Ala198-Ala182 bonds contributed in the formation of PmRab7-VP28 complex. Further studies on the amino acid residues and bonds may open new possibilities for preventing PmRab7-VP28 complex formation, thus reducing chances of WSD. The quantitative predictions provide a scope for experimental testing in future as well as endow with a straightforward evidence to comprehend cellular mechanisms underlying the disease.

Visceral leishmaniasis in rural bihar, India.

To identify factors associated with incidence of visceral leishmaniasis (VL), we surveyed 13,416 households in Bihar State, India. VL was associated with socioeconomic status, type of housing, and belonging to the Musahar caste. Annual coverage of indoor residual insecticide spraying was 12%. Increasing such spraying can greatly contribute to VL control.

Post-kala-azar dermal leishmaniasis in visceral leishmaniasis-endemic communities in Bihar, India.

We assessed the prevalence of post-kala-azar dermal leishmaniasis (PKDL), a late cutaneous manifestation of visceral leishmaniasis (VL), in 16 VL-endemic communities in Bihar, India. The prevalence of confirmed PKDL cases was 4.4 per 10 000 individuals and 7.8 if probable cases were also considered. The clinical history and treatment of the post-kala-azar dermal leishmaniasis cases are discussed.

FBIS: A regional DNA barcode archival & analysis system for Indian fishes.

UNLABELLED: DNA barcode is a new tool for taxon recognition and classification of biological organisms based on sequence of a fragment of mitochondrial gene, cytochrome c oxidase I (COI). In view of the growing importance of the fish DNA barcoding for species identification, molecular taxonomy and fish diversity conservation, we developed a Fish Barcode Information System (FBIS) for Indian fishes, which will serve as a regional DNA barcode archival and analysis system. The database presently contains 2334 sequence records of COI gene for 472 aquatic species belonging to 39 orders and 136 families, collected from available published data sources. Additionally, it contains information on phenotype, distribution and IUCN Red List status of fishes. The web version of FBIS was designed using MySQL, Perl and PHP under Linux operating platform to (a) store and manage the acquisition (b) analyze and explore DNA barcode records (c) identify species and estimate genetic divergence. FBIS has also been integrated with appropriate tools for retrieving and viewing information about the database statistics and taxonomy. It is expected that FBIS would be useful as a potent information system in fish molecular taxonomy, phylogeny and genomics. AVAILABILITY: The database is available for free at http://mail.nbfgr.res.in/fbis/

Fish Karyome: A karyological information network database of Indian Fishes.

'Fish Karyome', a database on karyological information of Indian fishes have been developed that serves as central source for karyotype data about Indian fishes compiled from the published literature. Fish Karyome has been intended to serve as a liaison tool for the researchers and contains karyological information about 171 out of 2438 finfish species reported in India and is publically available via World Wide Web. The database provides information on chromosome number, morphology, sex chromosomes, karyotype formula and cytogenetic markers etc. Additionally, it also provides the phenotypic information that includes species name, its classification, and locality of sample collection, common name, local name, sex, geographical distribution, and IUCN Red list status. Besides, fish and karyotype images, references for 171 finfish species have been included in the database. Fish Karyome has been developed using SQL Server 2008, a relational database management system, Microsoft's ASP.NET-2008 and Macromedia's FLASH Technology under Windows 7 operating environment. The system also enables users to input new information and images into the database, search and view the information and images of interest using various search options. Fish Karyome has wide range of applications in species characterization and identification, sex determination, chromosomal mapping, karyo-evolution and systematics of fishes.

Anesthesia for bone replacement surgery.

Advances in clinical medicine, improved understanding of pathophysiology, and the extensive application of medical technology have projected hitherto high risk and poor outcome surgical procedures into the category of routine and relatively good outcome surgeries. Bone replacement surgery is one amongst these and is wrought with a multitude of perioperative complexities. An understanding of these goes a long way in assisting in the final outcome for the patient. Here we present a review of the literature covering various issues involved during the different stages of the perioperative period.

Residual activity and integrity of PermaNet® 2.0 after 24 months of household use in a community randomised trial of long lasting insecticidal nets against visceral leishmaniasis in India and Nepal.

The World Health Organization (WHO) recommends several brands of long lasting insecticidal net (LN) for protection against insect vectors but also advises national programmes to monitor and evaluate performance under local conditions to help them select the most suitable LN for their setting. During the course of a community randomised trial of LNs against visceral leishmaniasis in northern India and Nepal, opportunity arose to assess the efficacy of PermaNet 2.0 (Vestergaard-Frandsen, Denmark) after two years of use against sandfly vectors. Between 63% (India) and 78% (Nepal) of LNs became holed over the course of two years, deltamethrin residues fell from 55 mg/m(2) to an average of 11.6 mg/m(2) (India) and 27.9 mg/m(2) (Nepal), but on the basis of bioassay criteria all LNs tested still met the WHO Pesticide Evaluation Scheme standard for LN effectiveness. Nets had on average only been washed 2.5 times (India) and 0.6 times (Nepal) by householders over the course of two years. The loss of insecticide was attributed to factors which had little or nothing to do with washing, such as handling, friction and torsion during daily use. Under conditions pertaining in this region of south Asia, and for two years at least, this brand of net continues to meet the criteria established by WHO for LNs.

Computational analysis of transcriptome of Indian major carp, Labeo rohita (Hamilton-Buchanan, 1822) for functional annotation.

A total of 1671 ESTs of Labeo rohita were retrieved from dbEST database and analysed for functional annotation using various computational approaches. The result indicated 1387 non-redundant (184 contigs and 1203 singletons) putative transcripts with an average length of 542 bp. These 1387 transcript sequences were matched with Refseq_RNA, UniGene and Swiss-Prot on high threshold cut-off for functional annotation along with help of gene ontology and SSRs markers. We developed extensive Perl programming based modules for processing all alignment files, comparing and extracting common hits from all files on a threshold, evaluating statistics for alignment results and assigning gene ontology terms. In this study, 92 putative transcripts predicted as orthologous genes and among those, 44 putative transcripts were annotated with gene ontology terms. The annotated orthologous gene of our result associated with some very important proteins of L. rohita involved in biotic and abiotic stresses and glucose metabolism of spermatogenic cells etc. The unidentified transcripts, if found important in expression profiling can be vital resource after re-sequencing. The predicted genes can further be used for enhancing productivity and controlling disease of L. rohita.
