We have studied the locally rotationally symmetric (LRS) Bianchi type-I cosmological model in f (R, T ) gravity (R is the Ricci scalar and T is the trace of the stress energy tensor) with Bulk viscous fluid as matter content. The model is constructed for the linear form f (R, T ) = R + 2f (T ). The exact solution of field equations is obtained by using a time varying deceleration parameter q for a suitable choice of the function f (T ). In this work, the bulk viscous pressurep is found to be negative and energy density ρ is found to be positive. The obtained model is anisotropic, accelerating and compatible with the results of astronomical observations. Also, some important features of physical parameters of this model have been discussed.

Background: Hodgkin’s lymphoma is a clonal malignant lymphoid proliferation, which originates from the germinal centers of B cells. This study was conducted to observe the socio-epidemiological profile of Hodgkin’s lymphoma in a tertiary cancer care centre from North East India. Methods: All patients from 0 to 18 years of age group with histopathologically proven diagnosis of HL, presenting to department of medical & pediatric oncology at Dr. Bhubaneswar Borooah cancer Institute during the period January 2012 to December 2019 were included in the study. Clinical parameters assessed included age, sex, locality, occupation, presenting symptoms, performance status, site of lymph node involvement, treatment modality, response to treatment, progression free survival and overall survival. Results: A total of 64 patients with histopathologically confirmed diagnosis of HL were registered in lymphoma joint clinic of BBCI from January 2012 to December 2019. The mean age was 12.68±4.71 years. Out of 64 patients, 54 (84.4%) belonged to rural areas and 10 patients (15.6%) to urban areas. Complete response was observed in 93.5% patient with limited risk disease, 73.24% with intermediate risk and 60% with advance stage. The overall survival and event free survival rates of 91% and 78.1%, respectively, were observed at 4 years. Conclusions: This study provides insight to incidence, demographic profile, overall response rates and survival pattern with other secondary objectives such as complete response rate, compliance rate and toxicity assessment among children with Hodgkin lymphoma belonging to Northeastern India.
