- Abstract
The present study investigates Mg-2Zn-1Ca/XMn alloys as biodegradable implants for orthopedic fracture fixation applications. The effect of the presence and progressive addition of manganese (X = 0.3, 0.5, and 0.7 wt.%) on the degradation, and post-corrosion compressive response were investigated. Results suggest that the addition of manganese at 0.5 wt.% improved the corrosion resistance of Mg-2Zn-1Ca alloys. The pH values stabilized for the 0.5Mn-containing alloy and displayed a lower corrosion rate when compared to other Mg-2Zn-1Ca/Mn alloys. Mg-2Zn-1Ca showed a progressive reduction in the compressive strength properties at the end of day 21 whereas Mg-2Zn-1Ca/0.3Mn and Mg-2Zn-1Ca/0.5Mn samples showed a decrease until day 14 and stabilized around the same strength range after day 21. The ability of Mg-2Zn-1Ca/0.5Mn alloy to develop a network of protective hydroxide and phosphate layers has resulted in the corrosion control of the alloy. Mg-2Zn-1Ca/0.7Mn displays segregation of Mn particles at the grain boundaries resulting in decreased corrosion protection. The mechanism behind the corrosion protection of Mg-2Zn-1Ca alloys was discussed.

- Abstract
Staphylococcus aureus is one of the most prevalent pathogens, and a causative agent of a variety of infections in humans and animals. Most studies concentrated on characterization of staphylococcus isolates and its antimicrobial resistance from various illness of veterinary importance, but there is no specific study that is available on isolates from reproductive tract of small ruminants and especially its semen. Hence, in the current study, a total of 48 semen samples were collected from healthy bucks of different breeds to investigate the occurrence of S. aureus. Antimicrobial resistance and virulence of the Staphylococcus isolates were determined to assess the adverse effects of them on buck fertility. The bacterial isolates were tentatively confirmed as Staphylococcus spp. based on the Gram's staining, growth on Mannitol salt agar and catalase test. Overall, 75% (n = 36) of the samples were positive for Staphylococcus spp. from the total 48 buck semen ejaculates from different breeds and among them 23 (63.89%) were coagulase-negative (CoNS) and 13 (36.11%) were coagulase-positive Staphylococcus (CoPS) strains. The species identified by molecular characterization are S. aureus, S. chromogenes, S. haemolyticus, S. sciuri, S. simulans, and S. epidermidis from buck semen. Further, these isolates exhibited varying degrees of multidrug resistance genotypically as well as phenotypically. The presence of antibiotic resistance and virulence genes may pose a potential threat to reproductive health of animals, the animal handlers and livestock keepers, while simultaneously highlighting the need for vigilant monitoring of these isolates at the time of semen cryopreservation., (© 2022.

- Abstract
Introduction: With nearly 1,612,505 industrial workers in Karnataka, controlling hypertension among them is necessary to reduce subsequent non-communicable diseases (NCDs). However, information on prevalence, incidence, and risk for hypertension among industrial workers is limited., Objectives: To estimate the prevalence, incidence proportion, incidence rate, and risk for hypertension among annual medical examination [AME] attendee cohort between 2010 and 2014 in an automobile industry in India., Materials and Methods: Longitudinal record analysis (cohort approach) of 640 regular AME attendees between 2010 and 2014 was performed to estimate incidence and incidence rates. Cox regression was conducted to estimate the risk for hypertension in the study period. Necessary permission and ethics clearance was obtained., Results and Conclusion: The prevalence of hypertension significantly increased from 8.8% in 2010 to 26.6% in 2014. The small increase in mean blood pressure (BP) resulted in large increases in the prevalence of hypertension. The incidence rate increased from 6.5 per 1000 person-months of observation in 2012 to 14.5 in 2014. No significant risk for hypertension was observed for the work department and type of plant. Results indicate a rising burden of hypertension with no specific risks associated with different work departments or types of plants. AME data is a utility value to monitor hypertension trends among employees and evaluate the effectiveness of worksite health programs to reduce hypertension., Competing Interests: There are no conflicts of interest., (Copyright: © 2022 Indian Journal of Occupational and Environmental Medicine.)

- Abstract
Background: Despite their higher prevalence, the Common Mental Disorders (CMDs) are under-recognized and under-treated resulting in huge disability. India, home to one-fifth of the global population, could offer insights for organizing better services for CMDs. However, the prevalence and resultant disability in the general population is unknown, and consequently, gaps in management or plan for services are enormous, by default overlooked., Aim: Estimating the current prevalence, disability, socioeconomic impact, and treatment gap of CMDs in a nationally representative sample from India. We attempt to identify the missed opportunities and list priorities for planning., Methodology: The National Mental Health Survey of India (2016) is a multisite nationwide household survey conducted across India using a uniform methodology. Overall, 39,532 adults were surveyed with a response rate of 88%. Diagnoses are based on the Mini International Neuropsychiatric Interview 6.0.0. CMDs for this analysis include depressive and anxiety disorders (generalized anxiety disorder, social phobia, agoraphobia, panic disorder, obsessive-compulsive disorder, and posttraumatic stress disorder)., Results: The weighted prevalence of current CMDs was 5·1% (95% CI: 5.06-5.13). Prevalence was highest in females, among the 40-59 years of age group, and in metros. Nearly 60% of them reported disabilities of varying severity. The treatment gap was 80·4%. On average, patients and their families spent ₹1500/month towards the treatment of CMDs., Conclusions: This survey gives valuable insights regarding the disability and treatment gap due to CMDs and is imperative for reframing mental health policies and planning interventions. This study also suggests an international investigation to understand the difference in the prevalence of CMDs in developing versus developed countries., Competing Interests: There are no conflicts of interest., (Copyright: © 2022 Indian Journal of Psychiatry.)

- Abstract
The role of calcium release-activated calcium (CRAC) channels is well characterized and is of particular importance in T-cell function. CRAC channels are involved in the pathogenesis of several autoimmune diseases, making it an attractive therapeutic target for treating inflammatory diseases, like rheumatoid arthritis (RA). A systematic structure-activity relationship study with the goal of optimizing lipophilicity successfully yielded two lead compounds, 36 and 37 . Both compounds showed decent potency and selectivity and a remarkable pharmacokinetic profile. Further characterization in in vivo RA models and subsequent histopathological evaluation of tissues led to the identification of 36 as a clinical candidate. Compound 36 displayed an excellent safety profile and had a sufficient safety margin to qualify it for use in human testing. Oral administration of 36 in Phase 1 clinical study in healthy volunteers established favorable safety, tolerability, and good target engagement as measured by levels of IL-2 and TNF-α.

Bijur G, Ramakrishna M, and Kotegar KA
- Abstract
Dynamic traffic of multicast communication in the Software Defined Network environment focused less though it is more natural and practical. In multicast communication, the traffic is dynamic due to the dynamic group memberships (i.e., participants join and leave the group anytime), which are not explored much in the previous research works. The multicast in dynamic traffic requires a method to handle dynamic group membership and minimum tree alteration for every join and leave of participants from the multicast group. This paper proposes a multicast tree construction algorithm, which considers receiving devices and network capability as base parameters to construct the multicast path. The proposed routing method uses Dijkstra's Shortest Path algorithm for initial tree formation, identifies a multicast path, and processes the Shortest Path Tree to reduce the overall hop count and path cost. The multicast tree generated by the proposed enables the dynamic join and leaves of participating devices with reduced tree alteration using more common paths to reach the devices. The implementation and results show that the proposed method works efficiently in resource utilization with a reduced hop count and quality for multicast communication in static and dynamic scenarios. Also, the results demonstrate that the proposed method generates a stable common path for multicast communication., (© 2021. The Author(s).)

- Abstract
Receptor clustering is the first and critical step to activate apoptosis by death receptor-5 (DR5). The recent discovery of the autoinhibitory DR5 ectodomain has challenged the long-standing view of its mechanistic activation by the natural ligand Apo2L. Because the autoinhibitory residues have remained unknown, here we characterize a crucial patch of positively charged residues (PPCR) in the highly variable domain of DR5. The PPCR electrostatically separates DR5 receptors to autoinhibit their clustering in the absence of ligand and antibody binding. Mutational substitution and antibody-mediated PPCR interference resulted in increased apoptotic cytotoxic function. A dually specific antibody that enables sustained tampering with PPCR function exceptionally enhanced DR5 clustering and apoptotic activation and distinctively improved the survival of animals bearing aggressive metastatic and recurrent tumors, whereas clinically tested DR5 antibodies without PPCR blockade function were largely ineffective. Our study provides mechanistic insights into DR5 activation and a therapeutic analytical design for potential clinical success., Competing Interests: Declaration of interests Some components of PPCR discovery and 2DEI design are part of a pending provisional patent by J.T.-S. on behalf of the University of Virginia License and Venture Group., (Copyright © 2021 The Author(s).

- Abstract
Together with the ongoing serious COVID-19 second wave in India, a serious fungal infection, mucormycosis has been increasingly found in COVID-19-recovered patients. Colloquially known as 'black fungus', mucormycosis commonly causes necrosis in the head and neck including the nose, paranasal sinuses, orbits, and facial bones, with possible intracranial spread. The disease causes high morbidity and mortality given that it progresses rapidly and diagnosis is often delayed. Given the sheer magnitude of the outbreak, the Indian Health Ministry has advised all states to declare mucormycosis an epidemic. Typically, the disease has been found to be linked to COVID-19 infections caused by the B.1.617.2 (Delta) variant, which has spread rapidly throughout the country. This variant has already become a cause for global concern, having spread to at least 40 countries, including the USA and UK. We present the findings of a study conducted on COVID-19 associated mucormycosis (CAM) patients, and discuss the associated risk factors to raise awareness for OMFS colleagues., (Copyright © 2021 The British Association of Oral and Maxillofacial Surgeons.

- Abstract
Objectives: Management of hemodynamically stable patients with penetrating neck trauma (PNT) has evolved in recent years with improvements in imaging technology. Computed tomography angiography (CTA) encompassing all zones of the neck has become part of the standard diagnostic algorithm for PNT patients who do not require immediate surgical intervention for vascular or aerodigestive injuries (ADI). Several studies have demonstrated favorable operating characteristics for CTA at excluding arterial injuries; however, consensus as to CTA's ability to detect ADI is lacking. We conducted a systematic review (PROSPERO registration number CRD42019133509) to answer the question Is CTA sufficient to rule out ADI in hemodynamically stable PNT patients without hard signs?, Methods: Investigators independently searched PubMed, EMBASE, and Web of Science from their inception to August 2020 for the search terms "penetrating neck injuries" and "CT scan." To be included, studies required sufficient data to construct a 2×2 table of CTA for ADI. The operating characteristics of CTA for detecting ADIs are reported as sensitivity, specificity, and likelihood ratios (LRs), with 95% confidence intervals (95% CIs). Bias in our studies was quantified by QUADAS-2., Results: Our search identified 1,242 citations with seven studies with moderate to high risk of bias meeting our inclusion/exclusion criteria and encompassing 877 subjects with an ADI prevalence of 13.4%. CTA for ADI had sensitivity of 92% (95% CI = 85% to 97%), specificity of 88% (95% CI = 85% to 90%), positive likelihood ratio of 12.2 (95% CI = 4.6 to 32), and negative LR of 0.14 (95% CI = 0.05 to 0.37). Of the 26 identified esophageal injuries across our studies that were diagnosed by either swallow studies or surgical exploration, five (19%, 95% CI = 8.1% to 38.3%) were initially missed by CTA., Conclusion: CTA alone is not sufficient to exclude esophageal injuries in PNT. Because delayed diagnosis is associated with increased morbidity, additional diagnostic interventions should be undertaken if there is remaining concern for esophageal injury., (© 2021 by the Society for Academic Emergency Medicine.)

- Abstract
Background: Prophylaxis for cerebral desaturation events (CDEs) during anesthesia in the beach chair position (BCP) for shoulder surgeries has not been evaluated. We systematically analyzed the effectiveness of various prophylactic measures used in this clinical setting., Methods: We performed a meta-analysis (PROSPERO; no. CRD42020167285) of trials reporting CDEs and regional cerebral oxygen saturation (rSO2) and jugular venous oxygen saturation (SjvO2) values in anesthetized patients undergoing shoulder surgery in BCP. Considering the type of prophylactic measures used (pharmacological or non-pharmacological), a subgroup analysis was planned. Outcomes included (1) rSO2 and SjvO2 data with and without prophylactic measures for CDEs, recorded for different time intervals, and (2) the number of patients experiencing CDEs and hypotension., Results: Twelve studies (786 patients) were included in the analysis. We observed lower absolute rSO2 values for early and all-time periods for vasoactive agent prophylaxis. The lowest achieved rSO2 values were also lower for vasoactive agent prophylaxis. Risk of CDEs was higher with vasoactive agent prophylaxis. Subgroup analysis identified targeted mild hypercarbia as effective in preserving cerebral oxygenation. Similarly, targeted mild hypercarbia prevented the fall in rSO2 with position change. Meta-regressions revealed statistically significant highest estimates for vasoactive agent prophylaxis in contrast to targeted mild hypercarbia. Likelihood of not developing CDEs was higher for targeted mild hypercarbia. In contrast to rSO2, most prophylactic methods reduced hypotensive episodes., Conclusions: Targeted mild hypercarbia can reduce BCP-related CDEs. Evidence does not favor prophylactic use of vasoactive agents for the prevention of cerebral desaturations irrespective of whether their use interferes with cerebral oximetry readings.

- Abstract
The primary objective of this study was to determine, using population-based data, whether the addition of postoperative radiotherapy (RT) provides an overall survival benefit in patients with early primary squamous cell carcinoma (SCC) of tongue. The study included the data of tongue cancer patients treated between January 2016 and July 2019 retrieved from our hospital database. Tumours limited to pathologic T1 and T2 category managed with primary surgery with or without postoperative external beam RT were included. Overall survival (OS) and disease-free survival (DFS) were the main outcomes of interest. A total of 211 cases of oral cancer were evaluated and all the patients had clear surgical and pathological margins. Postoperative adjuvant therapy (PORT) was received by 16 patients. Comparison of DFS and OS at 2-year follow-up depicted a similar outcome (p = 0.582 and p = 0.312 respectively). Findings from our study suggest that in the absence of any absolute advantage on quantifiable survival and disease control, it is necessary to define stringent criteria when advocating PORT in early tongue cancer., Competing Interests: Conflict of InterestThe authors declare no competing interests., (© Indian Association of Surgical Oncology 2021.)

- Abstract
Mental illness is a leading cause of global morbidity. Over 10% of the Indian population experience a mental health disorder yet deficits in knowledge and negative attitudes towards metal illness limit early identification and treatment. We explored the relationship among knowledge, attitudes and practice among generalist nurses working at a large tertiary care hospital in South India. Participants demonstrated positive attitudes and sufficient knowledge about mental illness, yet these variables did not predict practice when presented with a patient case scenario of postpartum depression-related mental distress in a non-psychiatric inpatient setting. Findings warrant application-based pedagogies to facilitate nurses' enhanced recognition and treatment of patients experiencing mental distress in non-psychiatric settings., (Copyright © 2021 Elsevier B.V.

- Abstract
Objective: To estimate the burden of active infection and anti-SARS-CoV-2 IgG antibodies in Karnataka, India, and to assess variation across geographical regions and risk groups., Methods: A cross-sectional survey of 16,416 people covering three risk groups was conducted between 3-16 September 2020 using the state of Karnataka's infrastructure of 290 healthcare facilities across all 30 districts. Participants were further classified into risk subgroups and sampled using stratified sampling. All participants were subjected to simultaneous detection of SARS-CoV-2 IgG using a commercial ELISA kit, SARS-CoV-2 antigen using a rapid antigen detection test (RAT) and reverse transcription-polymerase chain reaction (RT-PCR) for RNA detection. Maximum-likelihood estimation was used for joint estimation of the adjusted IgG, active and total prevalence (either IgG or active or both), while multinomial regression identified predictors., Results: The overall adjusted total prevalence of COVID-19 in Karnataka was 27.7% (95% CI 26.1-29.3), IgG 16.8% (15.5-18.1) and active infection fraction 12.6% (11.5-13.8). The case-to-infection ratio was 1:40 and the infection fatality rate was 0.05%. Influenza-like symptoms or contact with a COVID-19-positive patient were good predictors of active infection. RAT kits had higher sensitivity (68%) in symptomatic people compared with 47% in asymptomatic people., Conclusion: This sentinel-based population survey was the first comprehensive survey in India to provide accurate estimates of the COVID-19 burden. The findings provide a reasonable approximation of the population immunity threshold levels. Using existing surveillance platforms coupled with a syndromic approach and sampling framework enabled this model to be replicable., (Copyright © 2021. Published by Elsevier Ltd.)

- Abstract
We report the development and evaluation of safety and immunogenicity of a whole virion inactivated (WVI) SARS-CoV-2 vaccine (BBV152), adjuvanted with aluminum hydroxide gel (Algel), or TLR7/8 agonist chemisorbed Algel. We used a well-characterized SARS-CoV-2 strain and an established Vero cell platform to produce large-scale GMP-grade highly purified inactivated antigen. Product development and manufacturing process were carried out in a BSL-3 facility. Immunogenicity and safety were determined at two antigen concentrations (3μg and 6μg), with two different adjuvants, in mice, rats, and rabbits. Our results show that BBV152 vaccine formulations generated significantly high antigen-binding and neutralizing antibody titers (NAb), at both concentrations, in all three species with excellent safety profiles.

- Abstract
Background: The incidence of oropharyngeal carcinoma has been on the rise in recent decades. About 30% of patients who undergo definitive chemoradiation as the initial treatment present with residual/recurrent disease. In such a situation, surgical salvage either in the form of traditional open surgery or transoral robotic surgery (TORS) remains a viable treatment option. However, the extensive vascular supply of the posterior tongue and tonsillar bed increases the risk of perioperative bleeding, which is a key concern. The article describes the technique of selective pre-operative embolization to reduce the risk of perioperative bleeding and enumerate its advantages in providing a bloodless field during surgery., Methods: Prospective study of 5 patients with recurrent or residual midline BOT tumours who underwent TORS after selective lingual artery embolization at our centre., Results and Conclusions: None of the patients had any major perioperative bleeding or post procedural complications. All the patients after TORS had their tongue vascularity preserved with adequate recovery of tongue functions. Selective embolization of the feeder vessels provides a favorable bloodless surgical field without affecting the vascular integrity of the remnant tongue. This added advantage helps restoring the normal oral phase of swallowing., (© 2020 Wiley Periodicals LLC.)

- Abstract
Background: Mental illness affects over one-third of the Indian population, and only a little is known about the exact situation of health systems in Madhya Pradesh, India. Therefore, the present research work provides an assessment of state mental health systems in Madhya Pradesh., Methods: The present cross-sectional study was conducted as a part of National Mental Health Survey 2015-16 in 48 districts of Madhya Pradesh, to provide an overview of the status of mental health systems. Secondary data was also retrieved from the state office so as to present the situational analysis in a more comprehensive and inferential way. The proforma for the study was developed based on the experience gained from studies conducted earlier with World Health Organization's Assessment Instrument for Mental Health Systems (WHO-AIMS) and with WHO's Mental Health Atlas as the base for thematic analysis., Results: Out of 51 districts, 13.7% of the districts of the state have been covered under District Mental Health Program (DMHP) in 2015-16. Around 11.8% of district/general hospitals were involved in providing mental health services. The availability of psychiatrist was 0.05 per Lakh population. Around 0.2% of the total health budget was allocated by the state for the last financial year for mental health. The overall average score of Madhya Pradesh in the assessment of qualitative indicators was 31 out of 100 in the year 2015-16., Conclusion: There is huge scope and an urgent need to increase mental healthcare facilities (with upgradation of existing one) along the availability of mental healthcare staff., Competing Interests: The authors declares that there is no conflict of interest., (Copyright © 2021 Arun M.

- Abstract
The COVID-19 pandemic is a global health crisis that poses a great challenge to the public health system of affected countries. Safe and effective vaccines are needed to overcome this crisis. Here, we develop and assess the protective efficacy and immunogenicity of an inactivated SARS-CoV-2 vaccine in rhesus macaques. Twenty macaques were divided into four groups of five animals each. One group was administered a placebo, while three groups were immunized with three different vaccine candidates of BBV152 at 0 and 14 days. All the macaques were challenged with SARS-CoV-2 fourteen days after the second dose. The protective response was observed with increasing SARS-CoV-2 specific IgG and neutralizing antibody titers from 3
rd -week post-immunization. Viral clearance was observed from bronchoalveolar lavage fluid, nasal swab, throat swab and lung tissues at 7 days post-infection in the vaccinated groups. No evidence of pneumonia was observed by histopathological examination in vaccinated groups, unlike the placebo group which exhibited interstitial pneumonia and localization of viral antigen in the alveolar epithelium and macrophages by immunohistochemistry. This vaccine candidate BBV152 has completed Phase I/II (NCT04471519) clinical trials in India and is presently in phase III, data of this study substantiates the immunogenicity and protective efficacy of the vaccine candidates.- Published

- Abstract
Abstract: Quadriparesis after intramuscular trigger point injections for myofascial pain syndrome has been rarely reported in the literature. A 37-year-old male patient presented with myofascial pain syndrome and was given trigger point injections in trapezius muscles under ultrasound guidance. The patient noticed weakness in all the 4 limbs at approximately 12 hours after the procedure, which gradually progressed to functional quadriplegia at the time of presentation to the emergency department. On examination, he had quadriparesis with no sensory involvement and superficial reflexes were normal. MRI screening of the whole spine was unremarkable, and MRI brain suggested an incidental granuloma, which could not explain his symptoms. Blood tests revealed severe hypokalemia (2.2 mEq/L) and deranged thyroid function tests. Immediate potassium correction with intravenous and oral potassium chloride was initiated, and the patient showed improvement within 6 hours of initiating correction. Stress of the procedure, use of steroids with mineralocorticoid effects such as methylprednisolone, or deranged thyroid function tests may have acted as triggers to precipitate hypokalemic paralysis in the patient. Knowledge of this complication is essential as prompt diagnosis and timely management of hypokalemia can result in complete resolution of the symptoms., (Copyright © 2020 International Association for the Study of Pain.)

- Abstract
Issues: To review the burden of alcohol use in India, examine current policy initiatives and programs specific to India and provide a roadmap for future actions., Approach: A literature search was undertaken to review available published research papers, unpublished reports and anecdotal media information in the period 2000-2020 to assess the burden and pattern of alcohol use and appraise alcohol control policies in India., Key Findings: The per-capita alcohol consumption among individuals aged 15+ years was 5.7 L, which increased over time. Prevalence of alcohol use varied across states with considerable impact on the nation. Regulatory policies and alcohol control programs vary across Indian states, with poor enforcement and implementation. Taxation and pricing policies are revenue oriented. Policies are needed to address the aggressive and innovative marketing strategies of the alcohol industry. The system for regular monitoring of alcohol burden and conducting alcohol policy analysis needs strengthening., Implications: Alcohol use and its public health impact would continue to increase in India in the absence of effective policy and programs; the country may not achieve its stated goal of relative reduction of alcohol use prevalence by 10% by 2025., Conclusion: The prevailing alcohol control policies and programs in India have been less than fully effective in controlling the burden of alcohol use and its associated impact. There is a need for comprehensive, evidence-based and consensus-driven national alcohol control policy to appropriately guide and support the Indian states in regulating alcohol and reducing the associated burden. Effective implementations of such policies are central to its success., (© 2020 Australasian Professional Society on Alcohol and other Drugs.)

- Abstract
The availability of a safe and effective vaccine would be the eventual measure to deal with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) threat. Here, we have assessed the immunogenicity and protective efficacy of inactivated SARS-CoV-2 vaccine candidates BBV152A, BBV152B, and BBV152C in Syrian hamsters. Three dose vaccination regimes with vaccine candidates induced significant titers of SARS-CoV-2-specific IgG and neutralizing antibodies. BBV152A and BBV152B vaccine candidates remarkably generated a quick and robust immune response. Post-SARS-CoV-2 infection, vaccinated hamsters did not show any histopathological changes in the lungs. The protection of the hamster was evident by the rapid clearance of the virus from lower respiratory tract, reduced virus load in upper respiratory tract, absence of lung pathology, and robust humoral immune response. These findings confirm the immunogenic potential of the vaccine candidates and further protection of hamsters challenged with SARS-CoV-2. Of the three candidates, BBV152A showed the better response., Competing Interests: The authors declare no competing interests., (© 2021 The Author(s).)

- Abstract
The inherent ability of seeds (orthodox, intermediate, and recalcitrant seeds and vegetative propagules) to serve as carriers of pests and pathogens (hereafter referred to as pests) and the risk of transboundary spread along with the seed movement present a high-risk factor for international germplasm distribution activities. Quarantine and phytosanitary procedures have been established by many countries around the world to minimize seed-borne pest spread by screening export and import consignments of germplasm. The effectiveness of these time-consuming and cost-intensive procedures depends on the knowledge of pest distribution, availability of diagnostic tools for seed health testing, qualified operators, procedures for inspection, and seed phytosanitation. This review describes a unique multidisciplinary approach used by the CGIAR Germplasm Health Units (GHUs) in ensuring phytosanitary protection for the safe conservation and global movement of germplasm from the 11 CGIAR genebanks and breeding programs that acquire and distribute germplasm to and from all parts of the world for agricultural research and food security. We also present the challenges, lessons learned, and recommendations stemming from the experience of GHUs, which collaborate with the national quarantine systems to export and distribute about 100,000 germplasm samples annually to partners located in about 90 to 100 countries. Furthermore, we describe how GHUs adjust their procedures to stay in alignment with evolving phytosanitary regulations and pest risk scenarios. In conclusion, we state the benefits of globally coordinated phytosanitary networks for the prevention of the intercontinental spread of pests that are transmissible through plant propagation materials.

181. Use of Contemporary Groups in the Construction of Multi-Environment Trial Datasets for Selection in Plant Breeding Programs.

- Abstract
Plant breeding programs use multi-environment trial (MET) data to select superior lines, with the ultimate aim of increasing genetic gain. Selection accuracy can be improved with the use of advanced statistical analysis methods that employ informative models for genotype by environment interaction, include information on genetic relatedness and appropriately accommodate within-trial error variation. The gains will only be achieved, however, if the methods are applied to suitable MET datasets. In this paper we present an approach for constructing MET datasets that optimizes the information available for selection decisions. This is based on two new concepts that characterize the structure of a breeding program. The first is that of "contemporary groups," which are defined to be groups of lines that enter the initial testing stage of the breeding program in the same year. The second is that of "data bands," which are sequences of trials that correspond to the progression through stages of testing from year to year. MET datasets are then formed by combining bands of data in such a way as to trace the selection histories of lines within contemporary groups. Given a specified dataset, we use the A-optimality criterion from the model-based design literature to quantify the information for any given selection decision. We demonstrate the methods using two motivating examples from a durum and chickpea breeding program. Datasets constructed using contemporary groups and data bands are shown to be superior to other forms, in particular those that relate to a single year alone., Competing Interests: AG commenced employment with InterGrain when this manuscript was nearing completion. The remaining authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Smith, Ganesalingam, Lisle, Kadkol, Hobson and Cullis.)

- Abstract
Magnesium-Zinc based nanocomposites containing cerium oxide nanoparticles were developed in the present work. A systematic study on their microstructure, mechanical properties, in vitro degradation behaviour, and cytotoxicity are presented. It was found that the developed nanocomposites exhibited excellent strength and toughness that are superior to the commercially available magnesium alloys. From corrosion perspective, nanocomposites exhibited reduced pH increase compared to pure Mg with Mg-0.5Zn/0.5CeO
2 showing the least corrosion rate. Moreover, the developed nanocomposites exhibited no cytotoxicity to MC3T3-E1 pre-osteoblast cells. Based on the above findings, the feasibility of Mg-Zn/CeO2 nanocomposites for use as orthopaedic implants is systematically discussed. This study provides an insight into the development of new high-performance Mg alloy-rare earth oxide (REO)-based nanocomposites with superior mechanical properties and corrosion resistance while effectively avoiding the possible standing toxic effect of RE elements., (Copyright © 2020.

- Abstract
Background: First Zika virus (ZIKV) positive case from North India was detected on routine surveillance of Dengue-Like Illness in an 85-year old female. Objective of the study was to conduct an investigation for epidemiological, clinical and genomic analysis of first ZIKV outbreak in Rajasthan, North India and enhance routine ZIKV surveillance., Method: Outbreak investigation was performed in 3 Km radius of the index case among patient contacts, febrile cases, and pregnant women. Routine surveillance was enhanced to include samples from various districts of Rajasthan. Presence of ZIKV in serum and urine samples was detected by real time PCR test and CDC trioplex kit. Few ZIKV positive samples were sequenced using the next-generation sequencing method for genomic analysis., Result: On outbreak investigation 153/2043 (7.48%) cases were found positive: 1/153 (0.65%) among contacts, 90/153 (58.8%) in fever cases, 62/153(40.5%) in pregnant females. In routine surveillance, 6/4722 (0.12%) serum samples were ZIKV positive.Majority of patients had mild signs and symptoms, no case of microcephaly and Guillain- Barre Syndrome was seen, 25 (40.3%) pregnant females delivered healthy babies, four (6.4%) reported abortion and three (4.8%) had intrauterine death, one (1.6%) child had colorectal malformation and died after few days of birth. ZIKV was found to belong to Asian lineage, mutation related to enhanced neuro-virulence and transmission in animal models was not found., Conclusion: ZIKV was endogenous to India belonging to Asian Lineage. Disease profile of the ZIKV was asymptomatic to mild. No major anomaly was observed in infants born to ZIKV positive mothers; however, long term follow up of these children is required. There is need to scale up surveillance in the virology lab network of India for early detection and control., Summary Line: Zika virus infection was endogenous due to Asian Lineage with mild disease, no case of microcephaly or Guillain- Barre Syndrome was seen but children need to be followed for anomalies and surveillance of ZIKV needs to be enhanced in the country., (Copyright © 2020 The Authors.

- Abstract
Study Design: Retrospective cohort study., Purpose: To analyze the clinical and sphincteric outcomes and the extent of sexual dysfunction (SD) in subjects with cauda equina syndrome (CES) and to assess their correlation with patient-reported and clinical/urodynamic parameters., Overview of Literature: Despite vast literature present for CES, extent of the problem of SD in CES patients has not received enough attention as reflected by the limited information in literature. Little is known about exact prevalence at presentation or about the recovery. A better understanding of SD and bladder dysfunction in CES secondary to lumbar disc herniation is essential as it commonly occurs in the sexually active age group., Methods: All cases of cauda equine syndrome secondary to lumbar disc herniation were recruited. Biographical and clinical data, history, examination findings, operative variables, recovery, and SD were noted. Water cystometry and uroflowmetry were done pre- and postoperatively. The International Index of Erectile Function questionnaire and Female Sexual Function Index were used to assess SD among the men and women, respectively., Results: A total of 43 patients with up to 2.94-year follow-up were included. Urodynamic studies were found to correlate significantly with age, days of bladder involvement, perianal numbness, and motor weakness (p<0.01). In step-wise regression analysis, perianal sensation and overall motor weakness were bladder function determinants. Bladder function recovery was directly related to the number of delay days (t=2.30, p<0.05) and with unilateral leg pain (t=2.15, p<0.05). Significant correlation between SD with age and days of bladder involvement before surgery was found (p<0.01)., Conclusions: Surgery timing is related to patient's functional and sexual outcomes. Patients with unilateral leg pain and hypocontractile bladder have better outcomes. SD is a remarkable problem in CES.

- Abstract
The present study investigates Mg-SiO
2 nanocomposites as biodegradable implants for orthopedic and maxillofacial applications. The effect of presence and progressive addition of hollow silica nanoparticles (0.5, 1, and 1.5) vol.% on the microstructural, mechanical, degradation, and biocompatibility response of pure Mg were investigated. Results suggest that the increased addition of hollow silica nanoparticles resulted in a progressive increase in yield strength and ultimate compressive strength with Mg-1.5 vol.% SiO2 exhibiting superior enhancement. The response of Mg-SiO2 nanocomposites under the influence of Hanks' balanced salt solution revealed that the synthesized composites revealed lower corrosion rates, indicating rapid dynamic passivation when compared with pure Mg. Furthermore, cell adhesion and proliferation of osteoblast cells were noticeably higher than pure Mg with the addition of 1 vol.% SiO2 nanoparticle. The biocompatibility and the in vitro biodegradation of the Mg-SiO2 nanocomposites were influenced by the SiO2 content in pure Mg with Mg-0.5 vol.% SiO2 nanocomposite exhibiting the best corrosion resistance and biocompatibility when compared with other nanocomposites. Enhancement in mechanical, corrosion, and biocompatibility characteristics of Mg-SiO2 nanocomposites developed in this study are also compared with properties of other metallic biomaterials used in alloplastic mandibular reconstruction in a computational model.- Published

COVID-19 has spread to most countries in the world. However, there are some striking differences in how COVID-19 is behaving in different age groups. While data on COVID-19 is limited, children appear to be less susceptible to severe disease. These unique characteristics may be considered as a potential link to understanding the immune system and response in COVID-19 and lead to an effective cure to the disease. We suggest a possible role of loss of bridging between innate and adaptive immunity in COVID-19 and a potential treatment modality also discussed., (Copyright © 2020 Elsevier Ltd.

- Abstract
Carcinogens play a key role in cancer initiation. Conventional theories support the concept of genetic changes inducing tumorigenesis through proteomics and metabolomics which lead to cancer development. Current research provides evidence that metabolic genes may be altered long before mutation of tumour suppressor genes, strongly suggesting that metabolic changes may be preceding the changes seen at a genetic level. Since cancer has long been known to occur through gene regulation, an impaired cellular respiration without utilizing mitochondrial function has been an area of active interest. We hypothesize the activity of carcinogens as electron acceptors to disrupt the normal glycolysis cycle happening in a cell by acting as positive ligands. The continuous restoration of NAD+ to cytosol by oxidation of NADH with carcinogen as electron acceptor creates a metabolic pathway to assist in the carcinogenic process. This metabolic pathway continues through an adaptive process, supplemented by pyruvate converting to lactate providing a constant pool of NAD+ to continue the glycolytic pathway. We also hypothesize that carcinogenesis occurs as a precursor to metabolic stress which may promote altered genetic and protein expression causing aberrant epigenetic and cell signaling pathways., (Copyright © 2020 Elsevier Ltd.

- Abstract
The majority of clinical deaths in patients with triple-negative breast cancer (TNBC) are due to chemoresistance and aggressive metastases, with high prevalence in younger women of African ethnicity. Although tumorigenic drivers are numerous and varied, the drivers of metastatic transition remain largely unknown. Here, we uncovered a molecular dependence of TNBC tumors on the TRIM37 network, which enables tumor cells to resist chemotherapeutic as well as metastatic stress. TRIM37-directed histone H2A monoubiquitination enforces changes in DNA repair that rendered TP53-mutant TNBC cells resistant to chemotherapy. Chemotherapeutic drugs triggered a positive feedback loop via ATM/E2F1/STAT signaling, amplifying the TRIM37 network in chemoresistant cancer cells. High expression of TRIM37 induced transcriptomic changes characteristic of a metastatic phenotype, and inhibition of TRIM37 substantially reduced the in vivo propensity of TNBC cells. Selective delivery of TRIM37-specific antisense oligonucleotides using antifolate receptor 1-conjugated nanoparticles in combination with chemotherapy suppressed lung metastasis in spontaneous metastatic murine models. Collectively, these findings establish TRIM37 as a clinically relevant target with opportunities for therapeutic intervention. SIGNIFICANCE: TRIM37 drives aggressive TNBC biology by promoting resistance to chemotherapy and inducing a prometastatic transcriptional program; inhibition of TRIM37 increases chemotherapy efficacy and reduces metastasis risk in patients with TNBC., (©2020 American Association for Cancer Research.)

Infectious diseases and aetiological agents related to female reproductive systems were extensively covered compared to its male counterpart. There needs a proper study to bridge this gap, where microflora and infectious agents of both male and female reproductive are mutually intelligible. With this study, we aimed to evaluate the microbial contamination of the preputial cavity and also screened for abortion-causing agents which are zoonotic as well. In goats, such types of abortions are caused by Brucella melitensis, Chlamydophila, Campylobacter and Coxiella etc. One of the major sources of contamination of semen is the preputial cavity, which is exposed to the external environment leading to spread of infection into the female via semen straws or by natural service. In the current study, good quality bucks (n = 32, Barbari = 12, Jamunapari = 10, Jakhrana = 10) which were routinely used for semen collection were screened for their preputial swabs, for the presence of the above pathogens. For detection of Brucella melitensis, OMP31 based TaqMan® probe real-time PCR assay was used, and for Chlamydia, 16srRNA gene based SYBR® green real-time PCR assay was employed for detection of Chlamydophila abortus. While for Campylobacter spp. and Coxiella burnetii, 16srRNA gene based conventional PCR and Trans-PCR were used, respectively. In the current study, of the screened preputial swabs, none of them showed positive for Brucella and Coxiella, but of the screened 32 samples 17 showed positive for Chlamydia (53.13%) and two (6.25%) showed positive for Campylobacter spp. The current study emphasizes on the farms and laboratories which were regularly involved in screening of brucellosis also often overlook the other potential non-brucella pathogens, causing abortions eventually incurring severe economic losses to the goat keepers., (© 2020 Wiley-VCH GmbH.)

- Abstract
Tumour metastasis is one of the leading cause of cancer-related mortality. Circulating tumour cells (CTCs) have been implicated in loco-regional and distant metastasis and its role is being extensively studied in various malignancies, including those from the head and neck region. The main challenge in understanding their significance lies in the rarity of these cells in the blood. However, newer technologies have attempted to overcome these pitfalls. This review explores the evolution of CTC research and other related areas, including its biological significance, sustainability within the circulating vascular environment and possible clinical implications., (© 2020 John Wiley & Sons A/S.

- Abstract
Majority of patients infected with the COVID 19 virus display a mild to moderate course of disease and spontaneously recover at 14-20 days. However, about 15% of patients progress to severe stages and 2.5% of these patients succumb to this illness. Most patients with severe disease belong to the elderly age group (<65 years of age) and have multiple associated co-morbidities. The immune responses induced by the COVID 19 virus, during the incubation and non-severe stages, requires the early initiation of a specific adaptive immune response to eliminate the virus and prevent the progress to severe stages. In patients with a dysfunctional bridge adaptive immunity, the innate immune response becomes exaggerated due to the lack of feedback from the adaptive immune cells. The resultant cytokine storm is responsible for the severe lung injury leading to acute respiratory distress syndrome seen in COVID 19 patients. Mesenchymal stem cells are known to suppress overactive immune responses as well as bring about tissue regeneration and repair. This immuno-modulatory effect of MSCs could hold potential to manage a patient with severe symptoms of COVID 19 infection due to a dysfunctional adaptive immune system., (© 2020 Published by Elsevier Ltd.)

- Abstract
Ensuring optimum safety in schools to prevent injuries and promote safety of children is a mandate by the Constitution of India. However, there is limited evidence regarding safety and injury prevention in schools. This safety appraisal was conducted on a sample of 131 schools, selected by stratified random sampling in Bengaluru and Kolar districts in India. Trained investigators collected data using smart phone-assisted interview, observational methods and record review between 1 January and 31 March 2019. Safety was assessed across the domains of macro areas (policy, guidelines, committee, budget, coordination and training), physical infrastructure, road and transport safety, fire safety and first-aid services. Safety level (%) at each school was computed based on scores obtained in each domain. Overall safety level was at 50.8% of the assessment criteria and was relatively better in private schools (54%). Most schools scored less than 30% in domains of transport safety, fire safety and macro areas. Results highlight the need for implementing and augmenting safety measures in schools.

- Abstract
Oral cancer is easily detectable by physical (self) examination. However, many cases of oral cancer are detected late, which causes unnecessary morbidity and mortality. Screening of high-risk populations seems beneficial, but these populations are commonly located in regions with limited access to health care. The advent of information technology and its modern derivative artificial intelligence (AI) promises to improve oral cancer screening but to date, few efforts have been made to apply these techniques and relatively little research has been conducted to retrieve meaningful information from AI data. In this paper, we discuss the promise of AI to improve the quality and reach of oral cancer screening and its potential effect on improving mortality and unequal access to health care around the world., (© 2020 John Wiley & Sons A/S.

- Abstract
Background: Long-term follow-ups after receiving lycopene therapy for management of oral submucous fibrosis (OSMF) are scarce. The study aimed to assess the long-term efficacy of lycopene for management of OSMF symptoms., Methods: In this prospective clinical study, 400 clinically diagnosed early OSMF patients were assessed for the efficacy of lycopene in alleviation of burning sensation (BS) and reduced mouth opening (MO) symptoms in comparison to placebo. After 1-year follow-up, group A (lycopene group) was divided equally into group A1 and group A2. group A1 patients were retreated with lycopene and the A2 group was followed without retreatment. After 2-year follow-up, the Group A2 patients were advised retreatment but not followed as most of the patient did not agree for follow-up. However, group A1 patients were continued to follow-up every 6 months for a total three years. Statistical analysis was by independent sample t-test and P-value <.05 were considered as significant., Results: A statistically significant difference (P < .05) in BS and MO was found between group A and B with lycopene showing better results. At one-year follow-up, a statistically significant recurrence in the symptoms was found (P < .05) in the lycopene group (group A). After the second intervention, there was a statistically significant difference in the improvement of symptoms between the group A1 and A2 at 6 months and 1 year (P < .05) with group A1 (retreatment) showing better results., Conclusions: Treatment with lycopene led to improvement in the symptoms of OSMF in the present study. The results highlight the importance of retreatment of lycopene for its long-term effect on alleviation the symptoms of OSMF., (© 2020 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)
