‛Trophic switch' by catfish community from predation to scavenging modulated by human food discard in an estuarine bay. ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2024; 31:9183-9196. [PMID: 38190066 DOI: 10.1007/s11356-023-31749-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/20/2023] [Accepted: 12/23/2023] [Indexed: 01/09/2024]
Abstract
Benthic predatory catfishes are voracious and opportunistic predators and can easily shift their diet according to the availability of prey. In this study, feeding ecology of catfishes from two adjacent habitats of an estuarine bay is compared. The lower bay was relatively pristine as compared to the upper bay and was represented by two families of catfishes-Plotosidae and Ariidae, while the upper bay represented only ariid catfishes. Gut content analysis revealed that catfish predators from lower bay consumed conventional prey like teleosts and benthic invertebrates with a linear pattern of ontogenetic dietary shift. Plicofollis dussumieri and Plotosus canius occupied the position of top predators in the lower bay and were specialized feeders. Other predators like Plotosus lineatus, Arius arius, Arius jella, and Arius maculatus were generalist feeders occupying the position of mesopredators. However, in the upper bay, the catfish predators represented by Arius maculatus, Arius jella, and Arius arius predominantly fed on human discarded food. The easily available human food in the form of chicken, corn, and rice as noted from the investigated guts shows altered trophic guilds of ariid catfishes wherein only mid to large-sized catfish community was noted in this bay. A distinct "trophic switch" altered the trophic function from predation to scavenging which was observed in their feeding behavior. The anthropogenic impact in the form of unmanaged organic waste alters the role of predatory catfishes thereby restructuring the food web that may lead to unknown changes in the estuarine benthic ecosystems resulting in reduced ecosystem services.

Abstract
Diabetes is associated with a greater number of dental cavities. It is unclear, therefore, how potential risk factors such as salivary glucose, glycemic control and blood sugar could impact the onset of dental caries between people that have type 2 diabetes (T2D). Aim of the study - analyzing the risk factors for oral cavity disease in T2D patients. We analyzed the patient data including their dietary habits, dental hygiene practices, age and control of glycemic. The Indian dataset was used. Individual patient observations include the patient's diabetes classification as a range of medical attributes such as age, pregnancy, pedigree, glucose, body mass index, skin, blood pressure and insulin. The research discovered a significant correlation between poorly managed glycemic levels and dental caries are more prevalent in people with T2DM. High sugar consumption and poor oral hygiene habits have been identified as risk factors. These results highlight the need for integrating diabetes treatment measures with dental care to reduce dental caries in this susceptible group. Utilizing dental cavities into account improves oral health and has a positive impact on health outcomes for those with type 2 diabetes.

Abstract
Solution-processed quantum dot (QD) based blue emitters are of paramount importance in the field of optoelectronics. Despite large research efforts, examples of efficient deep blue/near UV-emitting QDs remain rare due to lack of luminescent wide band gap materials and high defect densities in the existing ones. Here, we introduce a novel type of QDs based on heavy metal free gallium sulfide (Ga2 S3 ) and their core/shell heterostructures Ga2 S3 /ZnS as well as Ga2 S3 /ZnS/Al2 O3 . The photoluminescence (PL) properties of core Ga2 S3 QDs exhibit various decay pathways due to intrinsic defects, resulting in a broad overall PL spectrum. We show that the overgrowth of the Ga2 S3 core QDs with a ZnS shell results in the suppression of the intrinsic defect-mediated states leading to efficient deep-blue emission at 400 nm. Passivation of the core/shell structure with amorphous alumina yields a further enhancement of the PL quantum yield approaching 50 % and leads to an excellent optical and colloidal stability. Finally, we develop a strategy for the aqueous phase transfer of the obtained QDs retaining 80 % of the initial fluorescence intensity.

Abstract
OBJECTIVE: To examine the short-term effect of ambient air pollution on daily acute respiratory emergency room visits among adults.METHODS: A time-series study (June 2017-February 2019) was carried out among adults (≥18 years) visiting a multi-specialty hospital in Delhi. We evaluated the association between the daily levels of particulate matter (PM) <2.5 μm in diameter (PM2.5) and PM <10 μm in diameter (PM10), ozone (O₃), nitrogen dioxide (NO₂), carbon monoxide (CO) and sulphur dioxide and daily count of emergency room (ER) visits for acute respiratory symptoms. Generalised additive model (GAM) was used with the Poisson link function to analyse the associations for 0-1 to 0-7 lag days.RESULTS: A total of 69,400 ER visits were recorded, of which 2,669 were by adults due to acute respiratory symptoms. At 0-7 lag days, an increment of 1 standard deviation in NO₂ and PM2.5 concentration was associated with a percentage increase in acute respiratory ER visits of respectively 53.0% (95% CI 30.84-78.97) and 19.5% (95% CI 4.53-36.65). During 0-7 lag days, a positive trend was observed at higher concentrations of CO (>1.86-3.28 mg/m³), while a negative significant association was observed at low concentrations of CO (<1.171 mg/m³).CONCLUSION: Short-term exposure to ambient NO2 and PM2.5 was associated with acute respiratory emergency visits of adults at lag 0-7 days.

ITPK1 Regulates Jasmonate-Controlled Root Development in Arabidopsis thaliana. Biomolecules 2023; 13:1368.

Abstract
Jasmonic acid (JA) is a plant hormone that regulates a plethora of physiological processes including immunity and development and is perceived by the F-Box protein, Coronatine-insensitive protein 1 (COI1). The discovery of inositol phosphates (InsPs) in the COI1 receptor complex highlights their role in JAperception. InsPs are phosphate-rich signaling molecules that control many aspects of plant physiology. Inositol pyrophosphates (PP-InsPs) are diphosphate containing InsP species, of which InsP7 and InsP8 are the best characterized ones. Different InsP and PP-InsP species are linked with JA-related plant immunity. However, role of PP-InsP species in regulating JA-dependent developmental processes are poorly understood. Recent identification of ITPK1 kinase, responsible for the production of 5-InsP7 from InsP6in planta, provides a platform to investigate the possible involvement of ITPK-derived InsP species in JA-related plant development. Here, in this study, we report that ITPK1-defective plants exhibit increased root growth inhibition to bioactive JA treatment. The itpk1 plants also show increased lateral root density when treated with JA. Notably, JA treatment does not increase ITPK1 protein levels. Gene expression analyses revealed that JA-biosynthetic genes are not differentially expressed in ITPK1-deficient plants. We further demonstrate that genes encoding different JAZ repressor proteins are severely down-regulated in ITPK1-defective plants. Taken together, our study highlights the role of ITPK1 in regulating JA-dependent root architecture development through controlling the expression of different JAZ repressor proteins.

Phthalate induced hormetic effect reveals susceptibility of gill compared to muscle tissue after depuration in commercially important fish (Etroplus suratensis). MARINE POLLUTION BULLETIN 2023; 194:115238.

Abstract
Effect of Bis-2ethylhexyl phthalate (DEHP) on commercially important tropical fish pearl spot has not been demonstrated at environmental concentrations along with depuration. The species is estuarine, juvenile and difficult to maintain but widely consumed and well distributed in tropical estuaries. Antioxidant activity of SOD, CAT and GPx was enhanced on all exposure days for gill and muscle suggesting high oxidative stress, except on day 5. Detoxifying enzyme-GST behaved differentially in gill and muscle tissue after depuration, depicting inhibited activity of GST in gill leading to lipid peroxidation. However, the muscle tissue was able to recover from stress after 7 days of depuration with the help of detoxifying enzymes. Overcompensation of antioxidant activity was observed over disruption of homeostasis defining hormesis effect. Integrated biomarker (IBR) index depicted high toxicity during entire exposure time, but after depuration, gill could not mediate LPO at lowest concentration (10 μg/l) while muscle tissue recovered, suggesting persistence of stress in gill.

Abstract
Nonpyrophoric aminophosphines reacted with indium(III) halides in the presence of zinc chloride have emerged as promising phosphorus precursors in the synthesis of colloidal indium phosphide (InP) quantum dots (QDs). Nonetheless, due to the required P/In ratio of 4:1, it remains challenging to prepare large-sized (>5 nm), near-infrared absorbing/emitting InP QDs using this synthetic scheme. Furthermore, the addition of zinc chloride leads to structural disorder and the formation of shallow trap states inducing spectral broadening. To overcome these limitations, we introduce a synthetic approach relying on the use of indium(I) halide, which acts as both the indium source and reducing agent for aminophosphine. The developed zinc-free, single-injection method gives access to tetrahedral InP QDs with an edge length > 10 nm and narrow size distribution. The first excitonic peak is tunable from 450 to 700 nm by changing the indium halide (InI, InBr, InCl). Kinetic studies using phosphorus NMR reveal the coexistence of two reaction pathways, the reduction of transaminated aminophosphine by In(I) and via redox disproportionation. Etching the surface of the obtained InP QDs at room temperature with in situ-generated hydrofluoric acid (HF) leads to strong photoluminescence (PL) emission with a quantum yield approaching 80%. Alternatively, surface passivation of the InP core QDs was achieved by low-temperature (140 °C) ZnS shelling using the monomolecular precursor zinc diethyldithiocarbamate. The obtained InP/ZnS core/shell QDs that emit in a range of 507-728 nm exhibit a small Stokes shift (110-120 meV) and a narrow PL line width (112 meV at 728 nm).

INOSITOL (1,3,4) TRIPHOSPHATE 5/6 KINASE1-dependent inositol polyphosphates regulate auxin responses in Arabidopsis. PLANT PHYSIOLOGY 2022; 190:2722-2738.

Abstract
The combinatorial phosphorylation of myo-inositol results in the generation of different inositol phosphates (InsPs), of which phytic acid (InsP6) is the most abundant species in eukaryotes. InsP6 is also an important precursor of the higher phosphorylated inositol pyrophosphates (PP-InsPs), such as InsP7 and InsP8, which are characterized by a diphosphate moiety and are also ubiquitously found in eukaryotic cells. While PP-InsPs regulate various cellular processes in animals and yeast, their biosynthesis and functions in plants has remained largely elusive because plant genomes do not encode canonical InsP6 kinases. Recent work has shown that Arabidopsis (Arabidopsis thaliana) INOSITOL (1,3,4) TRIPHOSPHATE 5/6 KINASE1 (ITPK1) and ITPK2 display in vitro InsP6 kinase activity and that, in planta, ITPK1 stimulates 5-InsP7 and InsP8 synthesis and regulates phosphate starvation responses. Here we report a critical role of ITPK1 in auxin-related processes that is independent of the ITPK1-controlled regulation of phosphate starvation responses. Those processes include primary root elongation, root hair development, leaf venation, thermomorphogenic and gravitropic responses, and sensitivity to exogenously applied auxin. We found that the recombinant auxin receptor complex, consisting of the F-Box protein TRANSPORT INHIBITOR RESPONSE1 (TIR1), ARABIDOPSIS SKP1 HOMOLOG 1 (ASK1), and the transcriptional repressor INDOLE-3-ACETIC ACID INDUCIBLE 7 (IAA7), binds to anionic inositol polyphosphates with high affinity. We further identified a physical interaction between ITPK1 and TIR1, suggesting a localized production of 5-InsP7, or another ITPK1-dependent InsP/PP-InsP isomer, to activate the auxin receptor complex. Finally, we demonstrate that ITPK1 and ITPK2 function redundantly to control auxin responses, as deduced from the auxin-insensitive phenotypes of itpk1 itpk2 double mutant plants. Our findings expand the mechanistic understanding of auxin perception and suggest that distinct inositol polyphosphates generated near auxin receptors help to fine-tune auxin sensitivity in plants.

Abstract
OBJECTIVE Although the elderly population remains at high risk for tuberculosis, studies addressing tuberculous meningitis (TBM) in this age group are scarce. The present study aimed to evaluate the spectrum and outcome of geriatric TBM and document differences between older and young patients. METHODS A prospective cohort study was conducted in the adult TBM patients admitted at PGIMER, Chandigarh (India). Consecutive older patients aged 60 years and above were enrolled from January 2019 to December 2020, and young adults aged 18-59 years were enrolled from July 2019 to December 2019. RESULTS Fifty-five older patients with a mean age of 66.6 years and 73 young patients with a mean age of 35.1 years were enrolled. At admission, older patients were more likely to have altered mental status (96.4% vs. 78.1%, P = 0.003) and advanced disease with British medical research council staging 2 or 3 (98.2% vs. 89.0%, P = 0.043); however, headache (38.2% vs. 67.1%, P = 0.001), vomiting (18.2% vs. 35.6%, P = 0.030) and fever (80.0% vs. 91.8%, P = 0.052) were less common. Cerebrospinal fluid (CSF) abnormalities were less marked in older patients, with a significant difference in median total cells (70 vs. 110/µl, P = 0.013). Hydrocephalous and infarct were common neuroimaging abnormalities in both groups; however, tuberculomas were significantly less in the elderly (15.1% vs. 35.2%, P = 0.012). Older patients had a significantly low survival rate (56.4% vs. 76.7%, P = 0.021). CONCLUSION Significant differences in clinical, CSF and radiological characteristics exist between elderly and young TBM patients, with survival remains dismal in the elderly.

Abstract
Inositol pyrophosphates are signaling molecules containing at least one phosphoanhydride bond that regulate a wide range of cellular processes in eukaryotes. With a cyclic array of phosphate esters and diphosphate groups around myo-inositol, these molecular messengers possess the highest charge density found in nature. Recent work deciphering inositol pyrophosphate biosynthesis in Arabidopsis revealed important functions of these messengers in nutrient sensing, hormone signaling, and plant immunity. However, despite the rapid hydrolysis of these molecules in plant extracts, very little is known about the molecular identity of the phosphohydrolases that convert these messengers back to their inositol polyphosphate precursors. Here, we investigate whether Arabidopsis Plant and Fungi Atypical Dual Specificity Phosphatases (PFA-DSP1-5) catalyze inositol pyrophosphate phosphohydrolase activity. We find that recombinant proteins of all five Arabidopsis PFA-DSP homologues display phosphohydrolase activity with a high specificity for the 5-β-phosphate of inositol pyrophosphates and only minor activity against the β-phosphates of 4-InsP7 and 6-InsP7. We further show that heterologous expression of Arabidopsis PFA-DSP1-5 rescues wortmannin sensitivity and deranged inositol pyrophosphate homeostasis caused by the deficiency of the PFA-DSP-type inositol pyrophosphate phosphohydrolase Siw14 in yeast. Heterologous expression in Nicotiana benthamiana leaves provided evidence that Arabidopsis PFA-DSP1 also displays 5-β-phosphate-specific inositol pyrophosphate phosphohydrolase activity in planta. Our findings lay the biochemical basis and provide the genetic tools to uncover the roles of inositol pyrophosphates in plant physiology and plant development.

Abstract
BACKGROUND Newborn oil massage is a widespread practice. Vigorous massage with potentially harmful products and forced removal of vernix may disrupt skin barrier integrity. Hospitalized, very-preterm infants treated with sunflower seed oil (SSO) have demonstrated improved growth but community-based data on growth and health outcomes are lacking. OBJECTIVES We aimed to test whether SSO therapy enhances neonatal growth and reduces morbidity at the population level. METHODS We conducted an open-label, controlled trial in rural Uttar Pradesh, India, randomly allocating 276 village clusters equally to comparison (usual care) and intervention comprised of promotion of improved massage practices exclusively with SSO, using intention-to-treat and per-protocol mixed-effects regression analysis. RESULTS We enrolled 13,478 and 13,109 newborn infants in demographically similar intervention and comparison arms, respectively. Adherence to exclusive SSO increased from 22.6% of intervention infants enrolled in the first study quartile to 37.2% in the last quartile. Intervention infants gained significantly more weight, by 0.94 g · kg-1 · d-1 (95% CI: 0.07, 1.82 g · kg-1 · d-1, P = 0.03), than comparison infants by intention-to-treat analysis. Restricted cubic spline regression revealed the largest benefits in weight gain (2-4 g · kg-1 · d-1) occurred in infants weighing <2000 g at birth. Weight gain in intervention infants was higher by 1.31 g · kg-1 · d-1 (95% CI: 0.17, 2.46 g · kg-1 · d-1; P = 0.02) by per-protocol analysis. Morbidities were similar by intention-to-treat analysis but in per-protocol analysis rates of hospitalization and of any illness were reduced by 36% (OR: 0.64; 95% CI: 0.44, 0.94; P = 0.02) and 44% (OR: 0.56; 95% CI: 0.40, 0.77; P < 0.001), respectively, in treated infants. CONCLUSIONS SSO therapy improved neonatal growth, and reduced morbidities when applied exclusively, across the facility-community continuum of care at the population level. Further research is needed to improve demand for recommended therapy inside hospital as well as in community settings, and to confirm these results in other settings.This trial was registered at www.isrctn.com as ISRCTN38965585 and http://ctri.nic.in as CTRI/2014/12/005282.

Abstract
India is the highest TB burden country in the world. The burden however is not uniform in different strata including tribal population - one of the key affected populations in the country. As the evidences from tribal population are hardly available, most of the policies and strategies implemented under National Tuberculosis Elimination Programme (NTEP) are usually based on the evidences from general populations. NTEP is continuously taking steps to strengthen TB services in tribal areas. The Social Action Plan including Tribal Action Plan is in place and the appropriate strategies are incorporated in the National Strategic Plan (NSP) to ensure universal access to quality TB services to vulnerable population groups. However, its implementation becomes challenging especially in tribal areas as different tribal groups have their own unique ways of dealing with health issues. These issues are therefore required to be addressed holistically involving all the stakeholders. In view of this a symposium was jointly organized by the Central TB Division (CTD), Govt. of India and ICMR - National Institute of Research in Tribal Health (NIRTH), Jabalpur on 17th and 18th December, 2019 at ICMR - NIRTH, Jabalpur. It provided an excellent platform for all the stakeholders from different parts of the country to share their experiences in tuberculosis particularly among marginalized populations. The recommendations emerged out of this interactive symposium highlight the sincere effort of NTEP to tackle TB situation in tribal population and show the way forward towards India's TB elimination goal by 2025 especially in hard to reach tribal areas.

Regulation of plant biotic interactions and abiotic stress responses by inositol polyphosphates. FRONTIERS IN PLANT SCIENCE 2022; 13:944515. [PMID: 36035672 PMCID: PMC9403785 DOI: 10.3389/fpls.2022.944515] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/15/2022] [Accepted: 07/20/2022] [Indexed: 05/14/2023]
Abstract
Inositol pyrophosphates (PP-InsPs), derivatives of inositol hexakisphosphate (phytic acid, InsP6) or lower inositol polyphosphates, are energy-rich signaling molecules that have critical regulatory functions in eukaryotes. In plants, the biosynthesis and the cellular targets of these messengers are not fully understood. This is because, in part, plants do not possess canonical InsP6 kinases and are able to synthesize PP-InsP isomers that appear to be absent in yeast or mammalian cells. This review will shed light on recent discoveries in the biosynthesis of these enigmatic messengers and on how they regulate important physiological processes in response to abiotic and biotic stresses in plants.

Risk factors for childhood illness and death in rural Uttar Pradesh, India: perspectives from the community, community health workers and facility staff. BMC Public Health 2021; 21:2027. [PMID: 34742283 PMCID: PMC8572490 DOI: 10.1186/s12889-021-12047-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2020] [Accepted: 10/19/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Uttar Pradesh (UP), India continues to have a high burden of mortality among young children despite recent improvement. Therefore, it is vital to understand the risk factors associated with under-five (U5) deaths and episodes of severe illness in order to deliver programs targeted at decreasing mortality among U5 children in UP. However, in rural UP, almost every child has one or more commonly described risk factors, such as low socioeconomic status or undernutrition. Determining how risk factors for childhood illness and death are understood by community members, community health workers and facility staff in rural UP is important so that programs can identify the most vulnerable children. METHODS This qualitative study was completed in three districts of UP that were part of a larger child health program. Twelve semi-structured interviews and 21 focus group discussions with 182 participants were conducted with community members (mothers and heads of households with U5 children), community health workers (CHWs; Accredited Social Health Activists and Auxiliary Nurse Midwives) and facility staff (medical officers and staff nurses). All interactions were recorded, transcribed and translated into English, coded and clustered by theme for analysis. The data presented are thematic areas that emerged around perceived risk factors for childhood illness and death. RESULTS There were key differences among the three groups regarding the explanatory perspectives for identified risk factors. Some perspectives were completely divergent, such as why the location of the housing was a risk factor, whereas others were convergent, including the impact of seasonality and certain occupational factors. The classic explanatory risk factors for childhood illness and death identified in household surveys were often perceived as key risk factors by facility staff but not community members. However, overlapping views were frequently expressed by two of the groups with the CHWs bridging the perspectives of the community members and facility staff. CONCLUSION The bridging views of the CHWs can be leveraged to identify and focus their activities on the most vulnerable children in the communities they serve, link them to facilities when they become ill and drive innovations in program delivery throughout the community-facility continuum.

Abstract
The management of drug-resistant (DR) tuberculosis (TB) remains a challenge particularly in remote rural areas of the country. Although the treatment with wholly oral drug regimens, including bedaquiline (BDQ) and delamanid, is rolled out under the National TB Elimination Program, little is known about its coverage and the effectiveness in hard-to-reach tribal areas. The present report describes the early identification and successful management, through team effort, of a case of extensively DR TB belonging to the Saharia tribe - a Particularly Vulnerable Tribal Groups (PVTGs) of Madhya Pradesh, which has a very high prevalence of TB. The BDQ-containing regimen was well tolerated and found effective with minimal side effects and contributed to the reduced time to culture conversion and radiological improvements. The concerted efforts and strategies need to be adopted for effective implementation of Programmatic management of DR TB (PMDT) guidelines in remote tribal areas of the country.

Abstract
OBJECTIVE We assessed the long-term survival of TB patients belonging to the Saharia tribe, a high TB burden community in Shivpuri district, Madhya Pradesh, central India. METHODS Population-based, longitudinal study conducted among 9756 Saharia population in 2013, and a resurvey done 2 years later in 2015 using the same methods. The status of the individuals during resurvey was recorded as non-TB, relapse and death. The deaths recorded in this period were used to measure the mortality among TB-affected population and the non-TB population in this cohort. RESULTS The standardised mortality ratio for the study cohort was 122.9 per 1000 population; males had higher mortality than females (129.9 vs. 96.8). The expected mortality among the non-TB population was 30.2, and the observed mortality among TB-affected population was 122.9 per 1000 population. CONCLUSION In the Saharia tribe, post-treatment mortality in the TB-affected population is significantly higher than in the general population. This highlights an urgent need for implementation of effective public health strategies to prevent disproportionate deaths among TB-affected individuals in resource-poor settings, and the importance of periodic follow-up of patients after cure/completion of treatment, especially in vulnerable populations.

Association of Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasma genitalium and Ureaplasma species infection and organism load with cervicitis in north Indian population. Lett Appl Microbiol 2021; 73:506-514.

Abstract
Cervicitis is predominantly caused by Neisseria gonorrhoeae and Chlamydia trachomatis, which accounts for almost half of all the cases of cervicitis. The role of newer organisms like Mycoplasma genitalium and Ureaplasma sp. and association of bacterial load with cervicitis are also not well established. So the study aimed to determine the relative frequency of these organisms and their load in association with cervicitis cases from north India. A case-control study involving 300 women was conducted using quantitative real-time PCR from endocervical swabs for identification of organisms and quantification of bacterial load. Among 150 cervicitis cases, C. trachomatis, N. gonorrhoeae, M. genitalium and Ureaplasma parvum were detected in 5 (3·3%), 10 (6·6%), 37(24·6%) and 47 (31·3%) respectively. Old age (<0·001, chi-squared test) and irregular menstrual cycles (<0·001, chi-squared test) were significantly associated with cervicitis. M genitalium was the only organism to be associated significantly with cervicitis with regard to age (<0·031) and symptoms like discharge (P < 0·033, chi-squared test) and dysuria (P < 0·044, chi-squared test) in multivariate analysis. Our finding suggests that the bacterial load of these organisms is not significantly associated with cervicitis. However, we found significant association of M. genitalium infection with clinical characteristics of cervicitis cases.

Abstract
AIMS The aim of this study was to identify the best combination of plant growth promoting bacteria (PGPB) and arbuscular mycorrhizal fungi (AMF) for biofortification and enhancing yield in wheat as well as improve soil health under field conditions. Another aim was to get insights into metabolite dynamics in plants treated with PGPB and AMF. METHODS AND RESULTS Different combinations of PGPB and AMF that gave good results in greenhouse study were used in a field study. The combined application of Bacillus subtilis CP4 (native PGPB) and AMF gave the best results with a significant increase in biomass, macronutrient and micronutrient content in wheat grains and improvement in yield-related parameters relative to the untreated control. PGPB and AMF treatment increased antioxidant enzymes and compounds and decreased the level of an oxidation marker. Metabolite profiling performed using Gas Chromatography-Mass Spectrometry (GC-MS) showed significant upregulation of specific organic acids, amino acids, sugars and sugar alcohols in plants treated with CP4 and AMF. The altered pathways due to CP4 and AMF inoculation mainly belong to carbohydrate and amino acid metabolism. A positive correlation was observed between some organic acids, sugars and amino acids with wheat growth and yield parameters. The activities of soil enzymes increased significantly with the best results shown by native PGPB and AMF combination. CONCLUSIONS A native bacterial isolate Bacillus subtilis CP4 in combination with AMF showed exceptional ability for biofortification and yield enhancement under field conditions. The upregulation of a number of metabolites showed correlation plant growth promotion and nutrients. SIGNIFICANCE AND IMPACT OF THE STUDY The combined application of native B. subtilis CP4 and AMF could offer a more sustainable approach for the development of a biofertilizer to enhance wheat nutrient content and production and soil health thereby advancing agriculture.

Abstract
SETTING A tertiary care hospital in North India. OBJECTIVE Tuberculosis (TB) remains a major public health problem in developing countries. The diagnosis of tuberculosis is still challenging in primary care settings in endemic countries like India. WHO has endorsed loop mediated isothermal amplification assay (LAMP) for TB as a replacement for smear microscopy for peripheral settings, however, more data is required to establish the specificity of this modality for the diagnosis of TB. In this study we aim to determine the diagnostic accuracy of the TB-LAMP assay in pulmonary tuberculosis. DESIGN A total of 236 patients (117 cases suspected of TB and 119 patients with non-TB pulmonary disease) were enrolled between February to July, 2018. Microbiological workups consisting of mycobacterial smear microscopy, culture, Xpert MTB/Rif and TB-LAMP were performed. RESULTS From 236 samples, 18 (7.6%) were excluded from the study. TB-LAMP and Xpert MTB/RIF were positive in 46 (21.1%) and 49 (22.5%) of the samples, respectively. The sensitivity of Xpert MTB/RIF and TB-LAMP, when culture was taken as a reference standard, was 90% (95%CI: 78.2-96.7) and 82% (95%CI: 68.6-91.4), respectively. The specificity, positive predictive value (PPV), and negative predictive value (NPV) of TB-LAMP assay were 96.8% (95%CI: 92.8-98.9), 89.1% (95%CI: 77.4-95.2), and 94.4% (95%CI: 90.4-96.5), respectively. CONCLUSION The TB-LAMP assay showed a good specificity and sensitivity for detection ofM. tuberculosis in adults, however, for programmatic implementation, more studies are required to be conducted at peripheral level healthcare settings.

Abstract
A newer application of data envelopment analysis (DEA) model with robust data envelopment analysis (RDEA) was presented for optimization of reaction variables of graft copolymerization of 2-hydroxyethyl methacrylate (HEMA) to Tamarindus indica seed polysaccharide (TSP). It helped to find out the most appropriate reaction conditions and variables (concentrations of HEMA and reaction initiator; temperature and time duration) for copolymerization. The data generated through the experimental work has been analyzed and indexed to predict the maximum %grafting. Sensitivity analysis was performed to check robustness of efficiency scores of CCR DEA efficient samples and a comparative analysis of the CCR DEA and RRDEA efficiency score has been done. The data obtained via real-time experiments and data predicted using computational modelling predictions were found to be in close vicinity.

Abstract
The COVID-19 pandemic, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is rapidly spreading across the globe due to its contagion nature. We hereby report the baseline permanent levels of two most toxic air pollutants in top ranked mega cities of India. This could be made possible for the first time due to the unprecedented COVID-19 lockdown emission scenario. The study also unfolds the association of COVID-19 with different environmental and weather markers. Although there are numerous confounding factors for the pandemic, we find a strong association of COVID-19 mortality with baseline PM2.5 levels (80% correlation) to which the population is chronically exposed and may be considered as one of the critical factors. The COVID-19 morbidity is found to be moderately anti-correlated with maximum temperature during the pandemic period (-56%). Findings although preliminary but provide a first line of information for epidemiologists and may be useful for the development of effective health risk management policies.

Abstract
The Xpert MTB/RIF Ultra is a recent advancement in molecular diagnostics of tuberculosis (TB) with higher sensitivity compared to its predecessor, the Xpert MTB/RIF assay. Prospective studies evaluating the performance of Xpert MTB/RIF Ultra in children with suspected TB are lacking. In this study, we evaluated the Xpert MTB/RIF Ultra for detection of Mycobacterium tuberculosis in samples from 156 children, of which one was excluded from the analysis. Of the remaining 155 samples, 6·5% (10/155), 21·3% (33/155), 20% (31/155) and 21·9% (34/155) were positive by smear examination, MGIT culture, Xpert MTB/RIF and Xpert MTB/RIF Ultra, respectively. The Xpert MTB/RIF and Xpert MTB/RIF Ultra had a similar overall sensitivity of 81·8% (95% CI: 64·5-93) and 84·8% (95% CI: 68·1-94·9), respectively. In suspected pediatric TB patients, the Xpert MTB/RIF Ultra had higher sensitivity compared to the Xpert MTB/RIF (72·7 vs 63·6). The AUC (area under the curve) of 0·905 for the Xpert MTB/RIF and 0·893 for the Xpert MTB/RIF Ultra indicate similar and good overall performance. Both Xpert assays were found to be equally efficient, however Xpert MTB/RIF Ultra showed better detection rate in suspected TB cases.

Abstract
Comminuted mandibular fracture poses a surgical challenge. Extensive comminution and absence of reference adds complexity particularly in anterior region. In this technical note, we describe a novel application of virtual surgical planning combined with 3D printing which grants precise anatomic reduction in such cases. Computed Tomography data (mandible) of another patient of same age and sex was utilized to create reference model by virtual surgical planning. Virtually created model was 3D printed and utilized for precontouring the reconstruction plate which assisted in achieving satisfactory outcome.

Abstract
The purpose of this study was to analyse whether costochondral grafts (CCG) fulfil temporomandibular joint (TMJ) reconstructive goals in children with TMJ ankylosis. A total of 23 patients (12 male, 11 female, aged 3-16 years) with unilateral or bilateral TMJ ankylosis operated on between January 2014 to April 2018 were included in the study. Maximal incisal opening (MIO), frequency of reankylosis, and growth of CCG, were evaluated at one month and six months for one year, and after that once yearly. Mouth opening changes with time were assessed by the Friedman test and growth was compared at follow up and analysed using the paired t test. Mean (range) follow up was 18 (12-48) months. Study results revealed follow up MIO at 12 months was highly significant (p=0.001). Out of 27 CCG studied, only one graft had undergone re-ankylosis. Based on the predetermined criteria using condylion to gnathion (Co-Gn) measurement in the posteroanterior cephalogram, CCG were categorised into optimum, sub-optimum, and overgrowth. However, long-standing TMJ ankylosis cases still displayed mandibular asymmetry at the end of the study, even with "optimal growth" radiographically. Overall comparison between the immediate postoperative and last follow up Co-Gn measurements in either unilateral or bilateral cases was not significant. CCG with functional matrix maintained the growth of the mandible and MIO in TMJ ankylosis. It can be concluded that CCG partially fulfils reconstructive goals; however, patients need to be followed up till the end of puberty for a substantive conclusion.

The unprecedented and rapidly spreading Coronavirus Disease-19 (COVID-19) pandemic has challenged public health care systems globally. Based on worldwide experience, India has initiated a nationwide lockdown to prevent the exponential surge of cases. During COVID-19, management of cardiovascular emergencies like acute Myocardial Infarction (MI) may be compromised. Cardiological Society of India (CSI) has ventured in this moment of crisis to evolve a consensus document for care of acute MI. However, this care should be individualized, based on local expertise and governmental advisories.

Abstract
Tuberculosis (TB) remains a major public health concern worldwide. To combat the global epidemic, the World Health Organization (WHO) launched the End TB Strategy in 2016. This strategy advocates patient-centered care. The WHO considers 'patients' as 'people' with interests and needs beyond their illness. TB care models centered around people aim to connect affected persons to health services and give support throughout treatment. Nevertheless, studies have shown that patients continue to experience negative attitudes from providers. The disempowering language used to refer to people with TB often place limits on the care that they receive. Common terminologies applied to patients who interrupt treatment perpetuate the 'blame game'. It is a moral obligation of providers to give care free from prejudice and discrimination, as articulated in the Patient's Charter for Tuberculosis Care. Researchers too have a duty to address underlying system barriers to relieve the unfair burden placed on patients. Lessons learned from the compassionate care provided to people living with HIV/AIDS (human immunodeficiency virus/acquired immune-deficiency syndrome) offer opportunities to address treatment adherence challenges. People-centered and patient-centered TB programs are necessary to end the epidemic. It is essential that providers and researchers find creative solutions for engaging patients throughout the care continuum and address health system factors.

Loop mediated isothermal amplification assay for detection of Trichomonas vaginalis in vaginal swabs among symptomatic women from North India. Lett Appl Microbiol 2020; 70:196-202. [PMID: 31808556 DOI: 10.1111/lam.13260] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2019] [Revised: 12/04/2019] [Accepted: 12/04/2019] [Indexed: 11/30/2022]
Abstract
Trichomonas vaginalis is one of the most common curable sexually transmitted pathogens infecting both men and women worldwide. Unlike traditional methods such as microscopy and culture, nucleic acid amplification tests rapidly detect this agent, assisting in treatment. Conventional polymerase chain reaction (PCR), the loop-mediated isothermal amplification (LAMP), and the Xpert TV assay were evaluated using 28 microscopy positive T. vaginalis samples and 125 microscopy negative samples from symptomatic females of reproductive age. The sensitivity of all tests was 100% and the specificity was 100%, 100%, and 99·2% for PCR, Xpert TV, and LAMP, respectively. The inter-rater reliability was excellent for PCR: Xpert TV (kappa-coefficient = 1) and good for LAMP assay: Xpert TV/PCR (kappa-coefficient = 0·98) and conventional PCR: LAMP (kappa-coefficient = 0·98). The study highlights the importance of PCR for screening T. vaginalis in women, particularly in laboratories where the Xpert-TV assay is not available or not affordable. The LAMP assay showed a lower positive predictive value which merits further evaluation. SIGNIFICANCE AND IMPACT OF THE STUDY: Trichomonas vaginalis is a common sexually transmitted pathogen associated with considerable morbidity and risk of complications. Due to the limitations of traditional diagnostic modalities, three molecular assays were compared: conventional polymerase chain reaction (PCR), Xpert TV assay, and loop mediated isothermal amplification (LAMP) assay for detecting T. vaginalis in symptomatic females. All tests had a sensitivity of 100% and the inter-rater reliability was excellent for PCR: Xpert TV, and good for LAMP assay: Xpert TV/PCR. The translational impact of this study lies in the possible use of conventional PCR and LAMP in laboratories where the Xpert TV assay is not available or not affordable.
