| 1 | Significant increase in HBV, HCV, HIV and syphilis infections among blood donors in West Bengal, Eastern India 2004-2005: Exploratory screening reveals high frequency of occult HBV infection显示文摘AIM: To evaluate the prevalence of markers of hepatitis B virus (HBV) and hepatitis C virus (HCV) and human immunodeficiency virus (HIV) among blood donors in Kolkata, Eastern India for two consecutive years and to conduct a pilot study to explore the presence of HBV DNA among hepatitis B surface antigen (HBsAg) negative but anti-HBc positive blood donors. METHODS: Seroprevalence of HBsAg, anti-HCV and anti-HIV was studied among 113 051 and 106 695 voluntary blood donors screened in 2004 and 2005, respectively. Moreover, a pilot study on 1027 HBsAg negative donors was carried out for evaluating the presence of HBV DNA by PCR on HBsAg negative/anti- HBc positive donors. RESULTS: A statistically significant increase in the prevalence of HBV (1448 vs 1768, P < 0.001), HIV (262 vs 374, P < 0.001), HCV (314 vs 372, P = 0.003) and syphilis (772 vs 853, P = 0.001) infections was noted among blood donors of Kolkata West Bengal in 2005 as compared to 2004. Moreover, the exploratory study on 1027 HBsAg negative donors revealed that 188 (18.3%)of them were anti-HBc positive out of which 21% were positive for HBV DNA. CONCLUSION: The findings of this study underscore the significantly increasing endemicity of hepatitis viruses, syphilis and HIV among the voluntary blood donors of our community. The pilot study indicates a high rate of prevalence of HBV DNA among HBsAg negative/anti-HBc positive donors and thus emphasizes the need for a more sensitive and stringent screening algorithm for blood donations. | Prasun Bhattacharya Partha Kumar Chandra Sibnarayan Datta Arup Banerjee Subhashish Chakraborty Krishnan Rajendran Subir Kumar Basu Sujit Kumar Bhattacharya Runu Chakravarty | 2007 | World Journal of Gastroenterology2007，13，27： | 9 |
| 2 | Distribution of hepatitis B virus genotypes:Phylogenetic analysis and virological characteristics of Genotype C circulating among HBV carriers in Kolkata,Eastern India显示文摘AIM: To evaluate the genotype distribution of hepatitis B virus (HBV) in Eastern India and to clarify the phyloge- netic origin and virological characteristics of the recently identifi ed genotype C in this region. METHODS: Genotype determination, T1762/A1764 mutation in the basal core promoter (BCP) and A1896 mutation in the precore region of 230 subjects were de- termined by restriction fragment length polymorphism method (RFLP) and the result was confi rmed by direct sequencing. RESULTS: The predominant genotypes D (HBV/D) and A (HBV/A) were detected in 131/230 (57%) and 57/230 (25%) samples. In addition, genotype C (HBV/C) was detected in 42/230 (18%) isolates. Surface gene region was sequenced from 45 isolates (27 HBV/C, 9 HBV/A and 9 HBV/D). Phylogenetic analysis revealed that all of the HBV/C sequences clustered with South East Asian subgenotype (HBV/Cs). The sequence data showed re- markable similarity with a Thai strain (AF068756) (99.5% ± 0.4% nucleotide identities) in 90% of the genotype C strains analyzed. T1762/A1764 mutation in BCP re- gion, associated with high ALT was signifi cantly higher in HBeAg negative isolates than HBeAg positive isolates. Frequency of A1896 mutation leading to HBeAg negativ- ity was low.CONCLUSION: The present study reports the genotypic distribution and the characteristics of partial genome sequences of HBV/C isolates from Eastern India. Low genetic diversity and confi nement of HBV/C in Eastern India possibly indicate a recent, limited, spread in this region. Genotype C with T1762/A1764 mutation has been reported to increase the risk for hepatocellular car- cinoma; therefore genotype C carriers in Eastern India should be carefully monitored. | Arup Banerjee Sibnarayan Datta Partha K Chandra Susanta Roychowdhury Chinmoy Kumar Panda Runu Chakravarty | 2006 | World Journal of Gastroenterology2006，12，37： | 3 |

| 5 | Pediatric thermal burn injury:A retrospective analysis from pediatric care institutes,Eastern India显示文摘Objective:Pediatric burns pose difficult healthcare issues in underdeveloped nations.Due to the scarcity of pediatric burn care facilities and qualified burn‑care staff,patients are frequently referred from a rural hospital.This study explores the burn‑treatment approach that could be used in rural hospitals in the absence of a dedicated pediatric burn care facility.Materials and Methods:A retrospective analysis of clinical data of 199 children who received treatment for burn‑injury in an isolated general surgical ward.Wound debridement under anesthesia at the earliest was the cornerstone of the treatment plan for this cohort.Until the wounds healed,the treatment was repeated every alternate day.The patient’s demographic data,number of surgical dressings,length of hospital stay,and outcome were analyzed.Results:The mean age of the patients was 51.68±23.79 months.The male‑female ratio was 1.45:1.The survival rate was 99.00%.The disability rate was 4.52%.Univariate logistic regression identified the age group,total body surface area affected,depth of the wound,and time of intervention as statistically significant variables(P<0.05)predicting the disfigurement.Multivariate logistic regression identified the time intervals between surgical intervention and injury as an important predictor of morbidity.In addition,delayed presentation and delayed intervention led to a longer hospital stay,and more interventions than the early intervention cohort.Conclusions:Early debridement accelerates recovery and lessens the need for future skin grafts or contracture procedures.This approach can be used in rural hospitals as well because pediatric burns can be manageable in an isolated general ward. | Kartik Chandra MANDAL Sourav ROY Pankaj Kumar HALDER Partha CHAKRABORTY L.NEILASANO Debasree GUHA | 2023 | Journal of Integrative Nursing2023，5，2： | 0 |
