Abstract
Background Haemoglobin disorders are unique and important health challenges for tribal populations. Hence, this study was undertaken with the aim to screen for haematological disorders, particularly anaemia and haemoglobinopathies, and to assess the sociodemographic profile in indigenous communities residing in and around Puducherry. Methods This was a community-based cross-sectional study conducted in both urban and rural areas of Puducherry district. We included 556 participants through convenient sampling. Trained research associates visited community to enrol eligible participants and sought information on sociodemographic parameters, health status, and disease profile, using a structured questionnaire; 2-3 ml of blood was collected in ethylene diamine tetra acid anticoagulant for analysis of haematology parameters. Results Median age of participants was 28 (17-42) years. Majority (58.8%) of the participants were female, married (52.8%). On thalassemia screening, none of the study participants had any haemoglobinopathy. The burden of anaemia among the study population was 38.7% (95% CI: 34.6-42.8%) and was higher among the female participants in both adolescent (54.5%) and adult (57.8%) age groups. The next common haematological abnormality observed was eosinophilia 21.4% (95% CI: 18-25%), more prevalent among males in the age group of 30-60 years. Conclusion More than half of the women were anaemic. Multidimensional planning and implementation are needed to improve the socio-economic profile and overall health of this vulnerable population.

Abstract
Purpose Chemo-immunotherapies like Fludarabine-Cyclophosphamide-Rituximab (FCR) are used for treatment of chronic lymphocytic leukemia (CLL) in young and fit patients while Bendamustine-Rituximab (BR) is used in older patients. In a resource constrained setting, managing toxicities of FCR chemotherapy is challenging and this study explores the use of upfront BR treatment in young CLL patients (age < 65). Methods Data of 61 CLL patients treated with the BR regimen between 2016 and 2020 was analysed. Overall-survival and progression-free-survival (OS and PFS) were compared between the two age groups (< / > 65 years) and correlated with the fluorescent-in-situ-hybridization (FISH) data, duration of illness and time to initiation of chemotherapy. Results Out of 61 patients, 34 (85%) were below 65 years. Five patients had del 17p and were excluded from the analysis. Forty patients had indications for treatment. Twenty-four (70.5%) of the forty patients achieved overall response; 10 developed progressive disease. The median OS and PFS was 1874 days (95% CI 1617-2130 days) and 1226 days (95% CI 1021-1432 days) respectively and were non inferior between the 2 age-groups. There were no correlations with clinical, laboratory or FISH parameters. The OS and PFS were better for patients with longer time to initiation of chemotherapy as compared to those with short duration of illness and short wait-and-watch periods (p < 0.000). Conclusions Our results show that BR chemotherapy can safely and effectively be used in upfront treatment of young CLL patients and provide durable responses.

Abstract
Hemoglobinopathy is a major concern among the tribal population which constitutes 8.6% of the total population, and West Bengal (WB) is the home to 5.3 million tribes. The present study was conducted on 52,880 tribal school students from all the districts of WB. Written informed consent and peripheral blood were collected for complete blood count and high-performance liquid chromatography analysis. Beta trait was 5.3%, sickle trait was 2.35%, and hemoglobin (Hb) E (HbE) trait was 1.4% in this population. About 37.8% of beta trait belonged to the Santal tribe and 21.5% belonged to Oraon. HbS is mainly found in Alipurduar and Jalpaiguri districts at the prevalence of 3.69% and 5.96%, respectively. HbE trait is found at 6.06% in Alipurduar, of which 51% of cases are from Mech tribe only found in this district. Unlike central and Western parts of India, HbS trait in WB was significantly low among the tribes. A high prevalence of consanguinity among the tribes is considered responsible for the high rate of hemoglobinopathy.

Abstract
Synchronous malignancies involving acute leukemia and a solid organ are rare. Bleeding per rectum is a common manifestation of acute leukemia during induction chemotherapy and might mask the presence of synchronous colorectal adenocarcinoma (CRC). Here we present two rare cases of acute leukemia with synchronous CRC. We also review previously reported synchronous malignancies to investigate demographics, diagnosis, and treatment modalities. Management of these cases requires a multispecialty approach.

Abstract
Background There is an age-old notion that family planning is women's responsibility disregarding the fact that men have equal responsibility in fertility regulation. Although male involvement is getting more recognition, studies on men's role in family planning are very few in the number in this part of the world. Objective To assess the knowledge, attitude and level of male involvement in family planning and to find out the factors associated with male involvement by contraceptive usage. Method A community based cross-sectional study was done from May to July 2021 among 165 currently married male, who had at least one child, living in Singur district of West Bengal. Cluster sampling method was done to select study participants and data were collected by pre-designed pretested questionnaire. Descriptive statistics, multivariable logistic regression was applied and data were analysed applying SPSS software. Result Only 36.4% participants were directly involved in family planning either by using condom or by withdrawal method but 65.5% participants were indirectly involved in family planning through spousal communication either by approving contraceptive use to their spouse or by decision making regarding family planning. Moreover, barrier of contraceptives usage were side effect (27%) and fear of impotence (25.5%). Male involvement was significantly associated with participant's education [AOR (95% CI= 3.63 (1.45-9.05)], caste [AOR (95% CI= 7.06 (2.55-19.51)], number of living children [AOR (95%CI= 5.01(1.95-12.87)], desire for more child [AOR (95% CI=0.34 (.13-.87)] and attitude on family planning [AOR (95% CI= 3.55 (1.41-8.94)]. Conclusion This study identified the prevailing gender norms in rural areas. Advocacy for male involvement in family planning by health personnel during counselling of eligible couples should help in increasing contraceptive coverage in the long run.

Abstract
Nanomedicine is seen as a potential central player in the delivery of personalized medicine. Biocompatibility issues of nanoparticles have largely been resolved over the past decade. Despite their tremendous progress, less than 1% of applied nanosystems can hit their intended target location, such as a solid tumor, and this remains an obstacle to their full ability and potential with a high translational value. Therefore, achieving immune-tolerable, blood-compatible, and biofriendly nanoparticles remains an unmet need. The translational success of nanoformulations from bench to bedside involves a thorough assessment of their design, compatibility beyond cytotoxicity such as immune toxicity, blood compatibility, and immune-mediated destruction/rejection/clearance profile. Here, we report a one-pot process-engineered synthesis of ultrasmall gold nanoparticles (uGNPs) suitable for better body and renal clearance delivery of their payloads. We have obtained uGNP sizes of as low as 3 nm and have engineered the synthesis to allow them to be accurately sized (almost nanometer by nanometer). The synthesized uGNPs are biocompatible and can easily be functionalized to carry drugs, peptides, antibodies, and other therapeutic molecules. We have performed in vitro cell viability assays, immunotoxicity assays, inflammatory cytokine analysis, a complement activation study, and blood coagulation studies with the uGNPs to confirm their safety. These can help to set up a long-term safety-benefit framework of experimentation to reveal whether any designed nanoparticles are immune-tolerable and can be used as payload carriers for next-generation vaccines, chemotherapeutic drugs, and theranostic agents with better body clearance ability and deep tissue penetration.

Abstract
Objective: The objective of this study is comparision of local and distant control rates with high-dose versus standard-dose radiotherapy along with concurrent chemotherapy in esophageal cancer – a prospective randomized study. Materials and Methods: Histologically proven Stage I–III patients with carcinoma esophagus were randomized into two groups. One group has been treated with standard-dose radiotherapy, i.e., a total dose of 50.4 Gy (1.8 Gy/day, 28#, 5 days/week). The other group (study arm) has received high-dose radiotherapy, i.e. a total dose of 64.8 Gy (1.8 Gy/day, 36#, 5 days/week). Both groups have received 2 cycles of 3 weekly concurrent chemotherapy (cisplatin 75 mg/m[2] on day 1 and 5-fluorouracil 750 mg/m[2] continuous intravenous infusion over 24 h on day 1–4). Follow-up response evaluation was done by both endoscopy and computed tomography scan after 6–8 weeks and after 2 months thereafter. Results: Out of a total of 28 patients, 68% showed a complete response, 14% showed partial response, and 18% patients developed progressive disease at first and subsequent follow up (median follow-up of 21 months). Among the complete response patients, rates were higher in high-dose group compared to standard-dose radiotherapy group (71% vs. 64%, P = 0.38). Treatment-related toxicities were acceptable in both groups. Conclusion: High-dose radiotherapy with concurrent chemotherapy seems to be more effective with acceptable toxicity in our study. However, further follow-up and large sample size may be required to validate the current study conclusion.

Abstract
Timely administration of appropriate empirical antibiotics in febrile neutropenia is crucial for favourable patient outcomes. There are guidelines in place recommending such antibiotics. However, regional variations and local epidemiological data must be evaluated to tailor the antibiotics for best possible and rational use. In this study, we audited the clinical and microbiological data of febrile neutropenic episodes occurring at a tertiary care haematology institution. Three hundred and ninety-three febrile neutropenic episodes occurring in 123 patients over a 1-year period were analysed for microbial profile, sensitivity and resistance patterns, and finally clinical outcomes. Gram-negative bacilli (GNB) blood stream infections (46.9%) were more prevalent as compared to gram-positive infections (41.9%). Overall mortality due to complicated neutropenic sepsis was 19.5% (24/123 patients). Increased resistance to carbapenems, beta-lactam beta-lactamase inhibitor combinations, aminoglycosides, fluoroquinolones, and cephalosporins were observed. Cefepime and tigecycline resistance were seen in 20% and 15% GNB isolates, respectively. Chest was the most frequent focus of infection, and acute myeloid leukaemia (AML) was the most common underlying disorder which correlated with the likelihood of death (p < 0.01). Multidrug-resistant GNB (esp. Klebsiella sp.) are still most worrisome isolates in neutropenic patients. Single-agent cefepime or piperacillin-tazobactam/tigecycline combination may be considered empirical agents. Chest infections and AML were independent predictors of poor clinical outcome in neutropenic patients. Regular audit of infections and antibiotic susceptibility data is needed to improve clinical outcomes in patients with febrile neutropenia.

Abstract
BACKGROUND Hemophilia A is an X chromosome-linked bleeding disorder caused by the deficiency of coagulation factor VIII (FVIII). The majority of the Indian population with hemophilia A use plasma-derived clotting factors and, in some instances, fresh frozen plasma and cryoprecipitate. Safer and more efficient treatment options are needed for this group of patients. OBJECTIVES To assess the safety of turoctocog alfa, a third-generation recombinant FVIII molecule, for the treatment and prophylaxis of bleeding episodes in previously treated Indian patients with moderate or severe hemophilia A. PATIENTS/METHODS This single-country, multicenter, open-label, nonrandomized trial enrolled 60 patients who received prophylactic treatment with turoctocog alfa for 8 weeks, which corresponded to a minimum of 20 exposure days. Confirmed development of FVIII inhibitors during the 8-week treatment period was evaluated. Other assessments included frequencies of adverse drug reactions (ARs), serious adverse reactions, drug-related allergic reactions, and infusion reactions during the 12-week period after the first treatment; hemostatic effect of turoctocog alfa for the treatment of bleeding episodes; and total annualized dose of turoctocog alfa administered during the 8-week treatment period. RESULTS No incidence of FVIII inhibitors was detected. No safety concerns such as ARs, serious ARs, or drug-related allergic reactions were noted. The hemostatic success rate for the treatment of bleeding episodes with turoctocog alfa was 81.6%. CONCLUSIONS The trial results demonstrated that turoctocog alfa is a safe treatment option for the prophylaxis and treatment of bleeding episodes in previously treated adolescent and adult patients with hemophilia A in the Indian population.

Abstract
Accurate and timely prenatal diagnosis of thalassemia is cornerstone to the success of thalassemia control; currently parents are screened for ß-thalassemia mutations by ARMS-PCR and subsequently chorionic villus sampling is done. We did an audit to ascertain whether the present design is adequate and determined the role of sequencing for pre-natal diagnosis of beta-thalassemia. This was a retrospective analysis of prenatal testing data collected over 10 years, (2010-2019). ARMS-PCR was done to identify the beta-globin mutation followed by CVS wherever indicated. Data was classified into 3 groups:-5 most commonly occurring mutations (group 1), less common mutations (group 2) and mutations not detected (group 3). Total number of cases studied were 2128. Mean age of the cohort was 29.30 years (range 18-48 years). Approximately 90% individuals had one of the 5 common mutations in decreasing order of frequency: IVS 1-5 G>C (1297/2128); Codon 26G>A/HbE (451/2128); codon 30G>C (69/2128); codon 15G>A (61/2128); FS 41-42-CTTT (48/2128). Undetected mutations amounted to 7.3% (156/2128). Mean haemoglobin was highest in the group 2 (12.46 g/dl) followed by the group 1 (11.20 g/dl) and least in group 3 (10.99 g/dl). MCV, MCH and MCHC showed similar trends. ANOVA on all these parameters, except RDW, within groups and for individual mutations, were statistically significant (p < 0.001). The hemogram-HPLC-ARMS-PCR-CVS approach is a cost-effective and established method but tends to miss out a considerable number of thalassemia mutations (~7%), emphasizing the role of sequencing in difficult cases. This needs to be addressed while formulating guidelines for thalassemia screening in future.

Abstract
HYPOTHESIS Dried blood droplet morphology may potentially serve as an alternative biomarker for several patho-physiological conditions. The deviant properties of the red blood cells and the abnormal composition of diseased samples are hypothesized to manifest through unique cell-cell and cell-substrate interactions leading to different morphological patterns. Identifying distinctive morphological trait from a large sample size and proposing confirmatory explanations are necessary to establish the signatory pattern as a potential biomarker to differentiate healthy and diseased samples. EXPERIMENTS Comprehensive experimental investigation was undertaken to identify the signatory dried blood droplet patterns. The corresponding image based analysis was in turn used to differentiate the blood samples with a specific haematological disorder "Thalassaemia" from healthy ones. Relevant theoretical analysis explored the role of cell-surface and cell-cell interactions pertinent to the formation of the distinct dried patterns. FINDINGS The differences observed in the dried blood patterns, specifically the radial crack lengths, were found to eventuate from the differences in the overall interaction energies of the system. A first-generation theoretical analysis, with the mean field approximation, also confirmed similar outcome and justified the role of the different physico-chemical properties of red blood cells in diseased samples resulting in shorter radial cracks.

Abstract
BACKGROUND We report the results of International Nosocomial Infection Control Consortium (INICC) surveillance study from January 2012 to December 2017 in 523 intensive care units (ICUs) in 45 countries from Latin America, Europe, Eastern Mediterranean, Southeast Asia, and Western Pacific. METHODS During the 6-year study period, prospective data from 532,483 ICU patients hospitalized in 242 hospitals, for an aggregate of 2,197,304 patient days, were collected through the INICC Surveillance Online System (ISOS). The Centers for Disease Control and Prevention-National Healthcare Safety Network (CDC-NHSN) definitions for device-associated health care-associated infection (DA-HAI) were applied. RESULTS Although device use in INICC ICUs was similar to that reported from CDC-NHSN ICUs, DA-HAI rates were higher in the INICC ICUs: in the medical-surgical ICUs, the pooled central line-associated bloodstream infection rate was higher (5.05 vs 0.8 per 1,000 central line-days); the ventilator-associated pneumonia rate was also higher (14.1 vs 0.9 per 1,000 ventilator-days,), as well as the rate of catheter-associated urinary tract infection (5.1 vs 1.7 per 1,000 catheter-days). From blood cultures samples, frequencies of resistance, such as of Pseudomonas aeruginosa to piperacillin-tazobactam (33.0% vs 18.3%), were also higher. CONCLUSIONS Despite a significant trend toward the reduction in INICC ICUs, DA-HAI rates are still much higher compared with CDC-NHSN's ICUs representing the developed world. It is INICC's main goal to provide basic and cost-effective resources, through the INICC Surveillance Online System to tackle the burden of DA-HAIs effectively.

We aim to study role of various genetic factors in determining severity of this disease. 243 diagnosed cases of HbE Beta thalassemia were included in this study. Patients were divided in two arms-transfusion dependent and non-transfusion dependent arms. Various factors (percentage of haemoglobin F, hemoglobin E, type of Beta mutation, Xmn1 polymorphism, alpha deletion, HPFH mutation) were evaluated in these patients. Xmn1 polymorphism (homozygous and heterozygous), presence of HPFH mutation and alpha deletion were more prevalent in NTDT arm versus TDT arm (p value < 0.001). Higher prevelance of severe beta mutation IVS 1-5 (G → C) mutation {64(61.54%) vs 38(27.34); p value < 0.001} was found in TDT arm when above factors were excluded from analysis. Higher mean haemoglobin F and mean Hemoglobin E percentage was associated with NTDT arm (p value < 0.001). Various factors (hemoglobin F and E percentage, Xmn1 polymorphism, HPFH mutation, alpha deletion and IVS 1-5 Beta mutation) were identified to affect severity of this cohort.

Abstract
Thalassaemias are the most common inherited autosomal recessive single gene disorders characterised by chronic hereditary haemolytic anaemia due to absence or reduced synthesis of one or more of the globin chains. Haemoglobin E (HbE)-β-thalassaemia is the genotype responsible for approximately one-half of all cases of severe β-thalassaemia worldwide. This study proposes to evaluate response of hydroxyurea in reducing transfusion requirements of severe HbE-β-thalassaemia patients, and its correlation with foetal haemoglobin (HbF) level and α-mutation. Hydroxyurea was started at a baseline dose in 82 transfusion-dependent HbE-β-thalassaemia patients. HbF levels and %F-cells were measured. β-Thalassaemia mutations and α-globin gene deletions and triplications were detected by amplification refractory mutation system (ARMS)-polymerase chain reaction (PCR) and Gap-PCR, respectively. Patients were categorised as good (41.5%), moderate (31.7%), and poor responders (26.8%) based on their decrease in transfusion requirements. Nine patients were excellent responders who became transfusion independent. The mean increase in HbF levels and %F-cells after therapy was correlated with decrease in transfusion requirements. Patients having a deletion of the α-globin gene were better responders. The response was proportional to the number of α-globin gene deletions. We conclude that hydroxyurea treatment decreases transfusion requirements, and the response correlates with α-globin gene deletions.

Abstract
Background & objectives Multiple transfusions in β-thalassaemia patients undergoing regular transfusion regimen are at a risk of developing transfusion transmitted infections, including hepatitis C virus (HCV). The present study was conducted to investigate the association of HCV viraemia and genotype with clinical parameters in HCV seroreactive β-thalassaemic individuals. Methods A total of 172 HCV seroreactive β-thalassaemic individuals aged between 2-35 yr with at least 25 units of blood transfusion were catagorized into four groups (2-12 yr, group 1; 13-19 yr, group 2; 20-29 yr, group 3; 30-35 yr, group 4). Aged matched control samples (n=87; β-thalassaemics without HCV infection) were also included. HCV RNA was detected by nested reverse transcriptase polymerase chain reaction (RT-PCR) based on 5' UTR of HCV genome, viral load was determined by real-time RT-PCR. Nested RT-PCR amplified partial core region was used for DNA sequencing. Liver function parameters [serum total bilirubin, alanine aminotransferase (ALT) and aspartate aminotransferase (AST)] were also determined. Results Of the 172 HCV seroreactive individuals, 59.30 per cent (n=102) were HCV RNA positive. HCV viral load ranged from 173 to 32.04×10[5] IU/ml; 87.65 per cent were infected with HCV genotype 3. Liver enzymes, such as ALT, AST and serum total bilirubin were significantly elevated in all age groups compared to control groups. Serum ferritin levels were found to be high in all individuals, but 16.27 per cent of HCV-infected individuals with >10,000 IU/ml viral load also showed high ferritin levels (>1500 μg/l) where the majority of them were infected with HCV genotype 3. Interpretation & conclusions HCV genotype 3 was the major circulating genotype among β-thalassaemia patients in this region. Our findings indicated an association between HCV replication and hepatic iron load and also highlighted the need for sensitive quantitative RT-PCR-based detection of HCV RNA in the high risk population.

Abstract
To study safety, efficacy (hemoglobin and hemoglobin F percentage increment in non-transfusion-dependent patients and decrease in transfusion frequency in transfusion-dependent patients), and determinants of response of decitabine in patients with HbE/β-thalassemia. Thirty patients of HbE/β-thalassemia (age > 18 years) were enrolled. Both transfusion-dependent (TDT) and non-transfusion-dependent (NTDT) patients were included after obtaining informed consent. Participants received 0.2 mg/kg of 5-aza-2'-deoxycytidine (decitabine) subcutaneously on 2 consecutive days a week for at least 12 weeks. Complete hemogram was done every 2 weeks and HPLC at every 4-week interval, until 2 months after last dose of drug for response assessment. Various factors like XMN1 polymorphism, IVS 1-5, alpha deletion, alpha triplication, baseline hemoglobin F, and baseline total hemoglobin were evaluated as determinants of response. Mean therapy period was 20.32 weeks. For NTDT group, peak mean increment in hemoglobin was 0.938 g/dl (p value < .001) and hemoglobin F percentage was 9.62% (p value < .001). Transfusion requirement decreased to 0.25 units compared to 0.96 units per patient per month for TDT patients over a period of last 1 year. Common side effects were respiratory tract infection (grade I/II) in three patients, chest tightness in one patient (grade I), and gastric erosion (grade III) in one patient. Decitabine is safe and efficacious in HbE/β-thalassemia.

Abstract
BACKGROUND Multitransfused thalassemic individuals are at high risk of developing transfusion transmitted Hepatitis C virus (HCV) infection. The aim of the study was to correlate the effects of host cytokine single nucleotide polymorphisms of TNF-α (-308 A/G) and IFN-γ (+874 A/T) in spontaneous or IFN induced treatment response in the HCV infected thalassemic individuals. METHODS A total of 427 HCV sero-reactive thalassemic individuals were processed for HCV viral genomic diversity and host gene polymorphisms analysis of TNF-α (-308 A/G) and IFN-γ (+874 A/T). RESULTS Out of 427 HCV sero-reactive individuals, 69.09% were found to be HCV RNA positive with genotype 3 as the predominant infecting strain (94.29%). Study highlighted that, A allele was significantly associated with (p < .05) spontaneous clearance of HCV infection and G allele was correlated with viral persistence at TNF-α (-308) gene polymorphism. Whereas in case of IFN-γ (+874) SNPs, A allele was significantly responsible (p < .05) for spontaneous clearance than T allele. Our study also indicated that in relapsed cases, IFN-γ (+874) T allele is more responsible than A allele. Though no significant correlation was found at both TNF-α (-308) and IFN-γ (+874) gene polymorphism among SVR and relapsed thalassemic patients. CONCLUSION A allele at both TNF-α (-308) and IFN-γ (+874) were strongly associated with spontaneous clearance among this population. But in case of SVR and relapsed cases no significant association was found. This cytokine gene polymorphisms pattern will help clinicians to take an informed decision about therapeutic management of HCV infected thalassemic individuals.

Abstract
OBJECTIVES To investigate the cause and effects of intracellular iron overload in lymphocytes of thalassemia major patients. METHODS Sixty-six thalassemia major patients having iron overload and 10 age-matched controls were chosen for the study. Blood sample was collected, and serum ferritin, oxidative stress; lymphocyte DNA damage were examined, and infective episodes were also counted. RESULTS Case-control analysis revealed significant oxidative stress, iron overload, DNA damage, and rate of infections in thalassemia cases as compared to controls. For cases, oxidative stress (ROS) and iron overload (serum ferritin) showed good correlation with R2 = 0.934 and correlation between DNA damage and ROS gave R2 = 0.961. We also demonstrated that intracellular iron overload in thalassemia caused oxidative damage of lymphocyte DNA as exhibited by DNA damage assay. The inference is further confirmed by partial inhibition of such damage by chelation of iron and the concurrent lowering of the ROS level in the presence of chelator deferasirox. CONCLUSION Therefore, intracellular iron overload caused DNA fragmentation, which may ultimately hamper lymphocyte function, and this may contribute to immune dysfunction and increased susceptibility to infections in thalassemia patients as indicated by the good correlation (R2 = 0.91) between lymphocyte DNA damage and rate of infection found in this study.

Abstract
Lymphoma patient presenting with isolated third nerve palsy is relatively rare, and diagnosis of underlying disease may be challenging. Until this date, less than 20 cases have been described in the literature. This is the case of a 3-year-old boy who presented to neurologist with ptosis of left eye for 8 days. On examination, abdominal mass was detected, and the child was referred to paediatric surgery department. Laparotomy and excision of the mass was done. Histopathology and immunohistochemistry of the mass confirmed it to be a case of Burkitt's lymphoma. At this point, the patient was referred to haematology department. Contrast-enhanced CT brain showed infiltration around left cavernous sinus. Patient was treated with two cycles of R-CODOX-M/R-IVAC. Ptosis improved completely within few days of starting chemotherapy. Follow-up positron emission tomography CT scan done after the second cycle of chemotherapy revealed no metabolically active disease.

Abstract
BACKGROUND Hepatitis C virus (HCV) is the major posttransfusion infection in multitransfused individuals in India with thalassemia major. To our knowledge, this study is the first conducted to correlate and comprehend the effects of the host interleukin (IL)28B gene polymorphism at loci rs12979860 and rs8099917 in spontaneous or interferon (IFN)-induced treatment response in the HCV-seroreactive individuals with thalassemia major. STUDY DESIGN AND METHODS A total of 557 HCV-seroreactive individuals with thalassemia were processed for HCV viral genotyping and host IL28B single-nucleotide polymorphism analysis at loci rs12979860 and rs8099917. RESULTS Of 557 individuals, 70.92% were found to be HCV RNA positive with Genotype 3 (95.18%) as predominant strain. A favorable CC allele at locus rs2979860 and TT allele at rs8099917 were 75.31 and 77.16%, respectively, which was strongly associated with spontaneous clearance of infection (p < 0.05). Of 85 IFN-treated cases, 56 achieved sustained virologic response (SVR) whereas 27 were relapsed cases. Among these patients who achieved SVR, a favorable CC/TT allele at rs12979860/rs8099917 was found to be predominant with 76.79 and 66.07%, respectively, whereas in the case of relapsed patients, unfavorable CT (55.56%) and TG (59.26%) alleles were found to be predominant. Additionally, low serum ferritin level was significantly associated with SVR. CONCLUSION CC at rs12979860 and TT at rs8099917 was strongly associated with spontaneous clearance and SVR in the population with thalassemia. Low age group and low serum ferritin level are important cofactors. This allelic pattern will aid clinicians in making an informed decision about prognosis and therapeutic management.

Abstract
BACKGROUND We report the results of International Nosocomial Infection Control Consortium (INICC) surveillance study from January 2010-December 2015 in 703 intensive care units (ICUs) in Latin America, Europe, Eastern Mediterranean, Southeast Asia, and Western Pacific. METHODS During the 6-year study period, using Centers for Disease Control and Prevention National Healthcare Safety Network (CDC-NHSN) definitions for device-associated health care-associated infection (DA-HAI), we collected prospective data from 861,284 patients hospitalized in INICC hospital ICUs for an aggregate of 3,506,562 days. RESULTS Although device use in INICC ICUs was similar to that reported from CDC-NHSN ICUs, DA-HAI rates were higher in the INICC ICUs: in the INICC medical-surgical ICUs, the pooled rate of central line-associated bloodstream infection, 4.1 per 1,000 central line-days, was nearly 5-fold higher than the 0.8 per 1,000 central line-days reported from comparable US ICUs, the overall rate of ventilator-associated pneumonia was also higher, 13.1 versus 0.9 per 1,000 ventilator-days, as was the rate of catheter-associated urinary tract infection, 5.07 versus 1.7 per 1,000 catheter-days. From blood cultures samples, frequencies of resistance of Pseudomonas isolates to amikacin (29.87% vs 10%) and to imipenem (44.3% vs 26.1%), and of Klebsiella pneumoniae isolates to ceftazidime (73.2% vs 28.8%) and to imipenem (43.27% vs 12.8%) were also higher in the INICC ICUs compared with CDC-NHSN ICUs. CONCLUSIONS Although DA-HAIs in INICC ICU patients continue to be higher than the rates reported in CDC-NSHN ICUs representing the developed world, we have observed a significant trend toward the reduction of DA-HAI rates in INICC ICUs as shown in each international report. It is INICC's main goal to continue facilitating education, training, and basic and cost-effective tools and resources, such as standardized forms and an online platform, to tackle this problem effectively and systematically.

Abstract
Thyroid abscess is a very rare clinical condition. It usually occurs in immunocompromised individuals or those with underlying malignancy. We report a case of multiple thyroid abscesses in the patient with Pre B acute lymphoblastic leukaemia which developed secondary to hematogenous spread from pyomyositis of right calf muscle. The patient developed sepsis-associated disseminated intravascular coagulation, which got resolved after thyroidectomy. He became afebrile after surgical intervention. Unfortunately, all the cultures were negative. Since there are few case series and reports, there are no clear guidelines for management of thyroid abscess. We conclude that though rare, thyroid abscess may be the cause of persistent fever in immunocompromised patients.

Abstract
The incidence of hereditary hemorrhagic disorders may vary according to the country and ethnic origin. Von Willebrand disease has emerged as the most common hereditary hemorrhagic disease in the industrialized world. In this series of 966 patients diagnosed to have inherited bleeding disorders, hemophilia A was the most common and was seen in 410 (42.4%) of the patients followed by platelet function defects seen in 380 (39.4%) of the patients. It is thus concluded that, similar to the white population, hemophilia A remains the most common bleeding disorder in the Indian population, although this is closely followed by platelet function defects in India, which are quite rare in whites. Von Willebrand disease is relatively rare in the Indian population.

Abstract
Forty-five patients with systemic lupus erythematosus (SLE) were investigated to evaluate the role of antiphospholipid antibodies in causation of thrombosis in Indians. The antiphospholipid antibodies studied included lupus anticoagulant (LAC), anticardiolipin antibodies (aCL), and anti-β2-glycoprotein 1 (aβ2-GP1). Twenty-seven patients (60%) had clinical manifestations of antiphospholipid antibody syndrome. Nineteen patients (42.2%) had a history of thrombosis, and eight (17.7%) had a history of recurrent fetal loss. aβ2-GP1 was (IgG) was positive in 23 (51.1%), aCL in 13 (28.8%), and LAC in four (8.8%). Of 19 patients with thrombosis, 14 (73.6%) were positive for aβ2-GP1, eight (42.1%) for aCL, and none of them was positive for LAC. Of the eight patients with recurrent fetal loss, two (25%) patients were positive for β2-GP1, five (62.5%) for aCL, and one (12.5%) for LAC. Of 18 patients without any manifestations of antiphospholipid syndrome (APS), seven patients (38.8%) were positive for aβ2-GP1, and three (16.6%) for aCL and LAC each. It is concluded that presence of aβ2-GP1 increases the risk of thrombosis and therefore should be looked for in all cases of SLE to consider prophylactic antithrombotic therapy in these patients.

Abstract
Fifty-three patients of thalassemia intermedia and 40 controls were studied for clinical evidence of thrombosis and laboratory evidence of hypercoagulable state. Thrombotic episodes were detected in 5 (9.4%) patients. Two of these 5 patients with thrombosis were splenectomized. Laboratory evaluation showed presence of thrombocytosis in 8 (15%), 5 of these were splenectomized. Platelet hyperaggregation was detected in 12 (22.2%) patients. Although rate of aggregation was slow in 7 (13.2%) patients, degree of aggregation was normal in these 7 patients and platelet hypoaggregation was not detected in any patient. Level of coagulation inhibitors protein C and protein S, and antithrombin III were decreased in 31 (58.4%) patients. There was no correlation between low level of protein C and protein S with hepatic dysfunction and iron overload. Antithrombin III level was decreased only in 8 (15%) patients. There was a statistically significant association between the lower level of this inhibitor and hepatic dysfunction. In conclusion, this study provides evidence for the existence of a chronic hypercoagulable state in patients with β thalassemia intermedia, and suggests that expression of a procoagulant surface by thalassemia intermedia red blood cells may be the major underlying factor giving rise to platelet and coagulation inhibitor abnormalities in these patients. These alterations are not related to iron overload or hepatic dysfunction.

Abstract
Multiple myeloma is a neoplastic disease of plasma cells accounting for 13 % of haematological malignancies and 2 % of all malignancies worldwide. Ascites may develop very rarely during the course of disease in multiple myeloma. We report the case of a 78 years old male with IgG lambda multiple myeloma who initially presented with plasmacytic ascites. An exhaustive review of world literature reveals 65 cases of ascites to have been reported in myeloma over a span of 62 years (1952 till date), usually developing in the course of treatment. This is the 7th case of plasmacytic ascites to have been diagnosed at initial presentation. We review the clinical features, diagnosis, prognostic significance and treatment of such cases.

Abstract
Mutation in the TP53 gene positively correlates with increased incidence of chemoresistance in different cancers. In this study, we investigated the mechanism of chemoresistance and epithelial-to-mesenchymal transition (EMT) in colorectal cancer involving the gain-of-function (GOF) mutant p53/ephrin-B2 signaling axis. Bioinformatic analysis of the NCI-60 data set and subsequent hub prediction identified EFNB2 as a possible GOF mutant p53 target gene, responsible for chemoresistance. We show that the mutant p53-NF-Y complex transcriptionally upregulates EFNB2 expression in response to DNA damage. Moreover, the acetylated form of mutant p53 protein is recruited on the EFNB2 promoter and positively regulates its expression in conjunction with coactivator p300. In vitro cell line and in vivo nude mice data show that EFNB2 silencing restores chemosensitivity in mutant p53-harboring tumors. In addition, we observed high expression of EFNB2 in patients having neoadjuvant non-responder colorectal carcinoma compared with those having responder version of the disease. In the course of deciphering the drug resistance mechanism, we also show that ephrin-B2 reverse signaling induces ABCG2 expression after drug treatment that involves JNK-c-Jun signaling in mutant p53 cells. Moreover, 5-fluorouracil-induced ephrin-B2 reverse signaling promotes tumorigenesis through the Src-ERK pathway, and drives EMT via the Src-FAK pathway. We thus conclude that targeting ephrin-B2 might enhance the therapeutic potential of DNA-damaging chemotherapeutic agents in mutant p53-bearing human tumors.

Abstract
Hemoglobin Eβ-thalassemia is by far the commonest form of thalassemia intermedia. Its phenotype ranges from mild anemia to severe transfusion-dependency necessitating splenectomy in many patients. The present study aimed to systematically analyze both clinical as well as laboratory parameters in profile of Eβ-thalassemia patients after splenectomy in terms of transfusion requirement, infections and other complications. Retrospective study conducted over a period of 3 years included 72 cases of splenectomized Eβ-thalassaemia patients, considering decrease in transfusion requirements, new complications, antibiotic, anti-malarial prophylaxis and iron chelation therapy. Out of 1380 registered Eβ-thalassemia patients, 618 (44.78 %) were regularly transfused and 72(5.22 %) underwent splenectomy. Mean age of diagnosis was 10.3 years. Nineteen patients (26.4 %) underwent splenectomy between 5 and 10 years, 38 cases (52.7 %) between 10 and 20 years. The leading cause (51.39 %) for splenectomy was mechanical discomfort. Mean steady state hemoglobin raised from pre-splenectomy level of 5.43-6.8 gm/dl after splenectomy. Mean transfusion requirement reduced from 18.1 to 7.8 units/year. Mean serum ferritin level increased from 907.58 to 1,091.6 ng/ml. Post-splenectomy; 21 (29.17 %) patients developed facial deformities, 17 (23.6 %) delayed pubertal growth, 11 (15.28 %) venous thromboembolism, five (6.94 %) pulmonary hypertension and four (5.5 %) had extramedullary hematopoiesis. Five (6.96 %) patients had documented bacterial infections and two (2.78 %) suffered from malaria. Forty eight patients (66.67 %) started with iron chelation therapy; but majority (52.7 %) stopped. Major advantage of splenectomy is reduced transfusion requirement, though it cannot prevent skeletal abnormalities and delayed pubertal growth. In resource constraint countries like India, routine anti-malarial and antibacterial prophylaxis is not desirable; iron chelation therapy should be encouraged and ensured.

Abstract
According to the 2008 revision of the World Health Organization (WHO) classification of myeloid malignancies, philadelphia chromosome (Ph)-negative myeloproliferative neoplasms (MPNs) include clonal, hematologic disorders such as polycythemia vera, primary myelofibrosis, and essential thrombocythemia. Recent years have witnessed major advances in the understanding of the molecular pathophysiology of these rare subgroups of chronic, myeloproliferative disorders. Identification of somatic mutations in genes associated with pathogenesis and evolution of these myeloproliferative conditions (Janus Kinase 2; myeloproliferative leukemia virus gene; calreticulin) led to substantial changes in the international guidelines for diagnosis and treatment of Ph-negative MPN during the last few years. The MPN-Working Group (MPN-WG), a panel of hematologists with expertise in MPN diagnosis and treatment from various parts of India, examined applicability of this latest clinical and scientific evidence in the context of hematology practice in India. This manuscript summarizes the consensus recommendations formulated by the MPN-WG that can be followed as a guideline for management of patients with Ph-negative MPN in the context of clinical practice in India.

Abstract
There is paucity of information from eastern India with regard to observed dominant micro-organisms causing febrile neutropenia (FN) in patients with haematological malignancies. To identify the prevalence of pathogenic microorganisms associated with FN. A total number of 268 episodes of FN were analysed from September'2010 to October'2013. The blood samples were inoculated into brain heart infusion broth, glucose broth, Hicombi dual performance media (Himedia, LQ-12) at 37° C for 168 h and Bactec method was also performed for these samples. Blood agar, chocolate agar, MacConkey's agar and cystine lactose electrolyte deficient agar were used for isolation of the microorganisms. A total number of 78 (29.10 %) episodes revealed positive growths. Gram negative bacilli and Gram positive cocci were isolated in 61.53 and 34.61 % cases respectively. The eight commonest isolates were Pseudomonas aeruginosa (14.10 %), methicillin resistant Staphylococcus aureus (MRSA-12.82 %), Acinetobacter sps (11.53 %), coagulase negative Staphylococcus (10.25 %), Klebsiella pneumoniae (8.97 %), Escherichia coli (8.97 %), ESBL E. coli (6.41 %), methicillin sensitive S. aureus (MSSA-6.41 %). Amongst other less common isolates were Citrobacter kosseri (3.84 %), Citrobacter freundii (2.56 %), Ralstonia paucula (2.56 %), Cedecia neteri (1.28 %), methicillin resistant coagulase negative Staphylococcus (2.56 %). Candida spp. including two cases of Candida non-albicans was isolated in 3.84 % of cases. P. aeruginosa was the commonest pathogenic isolates in FN patients associated with haematological malignancies in this study. Gram negative bacteria were the commonest isolates in FN including significant numbers of rare opportunistic micro-organisms.

Abstract
Introduction: Squamous cell cancer of the vulva is a rare disease with an annual incidence of two to three per 100,000 women. Lymph node metastasis is the most important prognostic factor for the recurrence and survival in vulval carcinoma. Materials and Methods: It is a retrospective study of 18 cases, operated in our institute from 2006 to 2009 and followed up till July, 2012. These patients were divided into two group of node positive and node negative and compared for recurrence and survival. Result: Ten patients had lymph node metastasis and eight had no lymph node metastasis. Recurrence rate was 40% and 12.5% in node positive and negative groups, respectively. Adjuvant radiation when given to node negative bulky tumor showed no recurrence compared to one out of two in the non-irradiated group. Survival was only 25% in node positive recurrent cases. Conclusion: Lymph node positivity added a great risk for future recurrence. Prophylactic radiation in node negative, bulky tumor is helpful.

Abstract
BACKGROUND Bone marrow changes are common throughout the course of HIV infection. There is scanty data addressing this issue in Indian subcontinent. The present study was aimed at characterizing the bone marrow changes in the antiretroviral naive HIV-infected Indian patients with anemia. MATERIALS AND METHODS This was a nonrandomized cross-sectional observational study undertaken over a period of 2 years. Forty-six randomly selected patients with documented anemia served as the study population. None of them was on any antiretroviral therapy or suffering from any known causes of anemia. All the patients underwent thorough evaluation, including bone marrow examination. RESULTS Majority of the patients had normocytic-normochromic anemia (63%), in tune with the available data. In most of the cases bone marrow was hypercellular (63.04%), although in a significant proportion it was found to be hypocellular (19.57%). Erythropoiesis was suppressed in 36.96% of patients. Dysplastic changes involving isolated cell lines ranged from 13.04% to 45.65%, dysmegakaryopoiesis being the most common, followed by dyserythropoiesis. Marrow plasmacytosis was detected in 23.91% of patients. No statistically significant correlation was detected in between immunological status (CD4 count) and marrow cellularity, myelodysplastic changes or marrow plasmacytosis. In a fair number of cases bone marrow examination aided in the diagnosis of opportunistic infections. CONCLUSIONS Bone marrow changes are common in Indian HIV-infected anemic population, particularly in the advanced stages of the disease. HIV infection should be considered in the differential diagnosis of patients with secondary myelodysplasia or unexplained bone marrow changes.
