T cell acute lymphoblastic leukaemia (T-ALL) is a genetically heterogeneous and aggressive form of malignancy. Although a number of recurrent fusion genes are reported in T-ALL, their involvement in disease stratification and therapeutic intervention is still controversial. Considering the prognostic value of STIL-TAL1 fusion and tyrosine kinase inhibitor (TKI) based therapeutic potential of NUP214-ABL1, the present study aimed to investigate their frequency and clinical correlation in pediatric T-ALL cases. Our cohort consisted of 48 T-ALL pediatric cases (age ≤ 12 years) with a median age of 6 years and male to female ratio of 20.51. The median TLC of the study group was noted to be 220,000/ cu mm with a range from 26,810/cu mm to 785,430/cu mm. By MLPA and RT-PCR analysis we observed that 11/48 cases (23%) showed STIL-TAL1 fusion and 4/48 cases (8.3%) had NUP214-ABL1 fusion gene. Both of the fusion genes did not show any significant correlation with any of the clinico-hematological or treatment outcome parameters. However, upon analysis of copy number variations (CNVs) with other clinically relevant genes, we found significant correlation between LEF1 (p = 0.024) and PTEN (p = 0.049) gene deletions with STIL/TAL1 fusion in T-ALL patients. NUP214-ABL1 fusion gene did not reveal any association with either CNVs or with survival. Although limited with the small cohort size and follow up, our study supports the similar frequency of these fusions as compared to other Asian and Western studies and also highlights utility of MLPA technique as a good diagnostic modality to screen for both STIL-TAL1 and NUP214-ABL1 fusions in a single assay with additional data on secondary copy number changes.Polymorphisms in the IL-2 gene are associated with various diseases and cancers including non-Hodgkin lymphoma (NHL). The aim of the study is to assess the impact of IL-2 genetic polymorphisms [- 330 T/G (rs2069762) and + 114 T/G (rs2069763)] on the susceptibility and prognosis of NHL. Sixty patients with NHL as well as 60 age and sex matched healthy control subjects are included in this study. IL-2 genotypes were determined by Polymerase Chain Reaction-Restriction Fragment length Polymorphism assay (PCR-RFLP). Our study revealed that both IL-2 rs2069762 and rs2069763 gene polymorphisms are associated with increased risk of developing NHL; OR = 3.609 (95% CI = 1.527-8.417) and 4.142 (95% CI = 1.637-10.538) respectively. Moreover, the simultaneous presence of both polymorphisms is associated with about 6 fold increased risk of developing NHL. Also, IL-2 rs2069762 and rs2069763 gene polymorphisms increase the risk of unfavorable prognosis with OR = 17.300 (95% CI = 3.392-87.725) and 10.424(95% CI = 1.870-58.413) respectively. These findings suggest that IL-2 (rs2069762) and (rs2069763) gene polymorphisms could be involved in the development of NHL.The study aimed at identifying the profile of gut colonization of patients with acute leukemia who underwent induction chemotherapy and its association with induction events and outcome. Baseline bacterial stool culture with resistance pattern of isolates were recorded. Multi-drug resistance was defined as resistance to at least two antibiotic classes including beta lactam and fluoroquinolones. During induction chemotherapy, blood and clinically indicated cultures were taken during febrile neutropenic episodes. Association studies were done between gut colonization and induction events/outcome. Among 109 patients enrolled, 71 (65.13%) patients undergoing induction chemotherapy were colonized with bacteria, with nearly 50% of colonizers harboring multi-drug resistant bacteria. Organisms isolated from stool pre-induction were mostly gram negative (98%), with Escherichia coli and Klebsiella pneumoniae being the commonest. 65.13% patients developed febrile neutropenia. Overall multi-drug resistant positivity during febrile neutropenia was 70.14%. Concordance of 8.45% was observed between isolates from stool and organisms isolated from cultures during febrile neutropenia. There were significant proportion of gut colonized gram-negative multi-drug resistance bacteria among patients with acute leukemia. There was a low concordance rate between baseline stool isolates and subsequent cultures during the induction. There was no significant association between gut colonization and induction events/outcomes studied.Therapy related acute leukemia consists of a unique subset of acute leukemia with an increased frequency of high risk cytogenetic and molecular abnormalities, dismal response to therapy, higher relapse rates and poor overall survival. Therapy related acute myeloid leukemia (t-AML) is a better defined disease entity than therapy related acute lymphoid leukemia (t-ALL). However, in recent times, t-ALL is also being increasingly recognized and extensively studied. Therapy related acute myeloid leukemia is usually classified together with therapy related myelodysplastic syndrome. However, the management of these two diseases maybe different regarding needs of induction chemotherapy and eligibility for upfront allogeneic hematopoietic stem cell transplantation (Allo HSCT). There is also evidence regarding differences in prognosis and outcomes between these two entities. Allo HSCT offers a potential for cure in t-AML and t-ALL. However, existing literature on the same is confounded by inclusion of t-MDS and secondary acute leukemias. Here we review the current evidence on the outcomes and predictors of outcomes of Allo HSCT in the management of therapy related acute leukemias. We also shed light into the under-representation of therapy related leukemias in clinical trials. selleck chemicals This stresses the need for prospective trials incorporating measurable residual disease monitoring and sequential next generation sequencing based genomic data for accurate prognostication and management of therapy related acute leukemia.This paper examines the long- and short-run spillover effects of US quantitative easing (QE) on the benchmark 10-year Indian government bond (IGB) yield by Autoregressive Distributed Lag (ARDL) bounds testing co-integration approach using monthly data from September 2008 to June 2019. The results show that a 10%-point rise in US QE led to a 4 bp rise in yields. The counterfactual analysis shows that volatility of the yields would have been less without the QE. During the episodes of QE, the Reserve Bank of India (RBI) had to alter its policy rate and engage in open-market operations (OMOs) to simultaneously maintain liquidity in the system and reduce the volatility of interest rates. Spillover on the debt yield leads to mispricing of assets and partial loss of the monetary-policy autonomy of the RBI.Pulmonary mucormycosis (PM) is a rare disease. Literature about the surgical management of PM in India is sparse. Recently, there has been a surge in the number of cases of mucormycosis in association with the coronavirus disease 2019 (COVID-19) pandemic, igniting the interest in PM. Hence, we endeavoured to analyse our surgical experience in treating PM prior to the pandemic, in a tertiary care centre, to provide insight into this disease. Data of 10 adult patients with isolated PM, who underwent surgery between the years 2009 and 2020, and maintained in our departmental database, were retrieved and analysed.Lung transplantation has come of age in India. This article aims to trace the evolution of lung transplantation in India from its humble beginnings in 1999 to the current scenario spanning a period of 22 years. Right from the passing of the Act legalising deceased organ transplantation, its amendments and rules-to the development of transplant regulatory bodies-both at national and state levels, the journey thus far has been chronicled. Description of the initial cases at sporadic centres which has now proliferated to many centres now across many states has been elaborated on. The impacts on evolution of lung transplantation by the governmental transplant organisations, non-governmental organisations, and the medical professional societies are described. Publications related to lung transplantation from India are mentioned. Situations specific to India, current scenario of lung transplantation, and future directions are discussed. A brief mention of our experience with lung transplantation has also been made.The trucking industry is the backbone of domestic supply chains. In the context of the COVID-19 pandemic, road transportation has been essential to guarantee the supply of basic goods to confined urban areas. However, the connectivity of the trucking network can also act as an efficient virus spreader. This paper applies network science to uncover the characteristics of the trucking network in one major Latin American country -Colombia- and provides evidence on freight networks' ability to spread contagious diseases spatially. Network metrics, official COVID-19 records at the municipality level, and a zero-inflated negative binomial model are used to test the association between network topology and confirmed COVID-19 cases. Results suggest that (i) the number of COVID-19 cases in a municipality is linked to its level and type of network centrality; and (ii) being a port-city and a primary economic hub in the trucking network is associated with a higher probability of contracting earlier a pandemic. Based on these results, a risk-based approach is proposed to help policymakers implement containment measures.The global outbreak of COVID-19 has further exposed deficiencies in city logistics based on human and ground roads, such as poor emergency response capacity and high risk of infection during transportation. Metro-based underground logistics system (M-ULS) may be an innovative approach to deal with this city-level disaster due to its efficient operation, contactless and driverless characteristics. However, the market evolution process and the quantitative calculation framework of comprehensive benefits after the application of M-ULS are still unclear, which has become a problem of mutual restriction with the extensive application of M-ULS. This paper attempts to use the system dynamics method, based on the real-world simulation, to analyze the quantitative relationship between the M-ULS implementation and the city logistics performance under epidemic outbreaks. Wuhan city in China was selected as the empirical background, and five simulation scenarios were set under different implementation strategies of M-ULS in response to the epidemic. Six variables were selected to measure city logistics performance and M-ULS operation status, including demand fill-rate, unit delivery time, total deprivation cost, total transportation cost, total number of susceptible people, and utilization rate of M-ULS. The results show that M-ULS is effective in improving the performance of city logistics and responding to the epidemic. The delivery time and transportation cost have a strong impact on the market share of M-ULS. Finally, a set of incentive policies was designed to promote the adoption of M-ULS. The findings not only provide a method for evaluating the overall performance of M-ULS, but also provide a unique perspective for promoting the implementation of M-ULS and responding to the transportation challenges brought by the epidemic.
