Background Some studies revealed that despite having sufficient sun exposure and dietary supply, the level of serum 25(OH)D in Bangladeshi adults is lower than its normal range. Genetic pattern of an individual is also an essential factor that regulates the level of serum 25(OH)D. However, the genetic variations of CYP2R1 (rs10741657) and their association with low serum 25(OH)D level in Bangladeshi adults are yet to be explored. Objective This study was conducted to determine the frequency of variants of rs10741657 of CYP2R1 gene and its association with low serum 25(OH)D level among Bangladeshi adults. Method This pilot study was conducted among thirty individuals with low serum 25(OH)D level as the study population and ten subjects with sufficient serum 25(OH)D level as controls based on the inclusion and exclusion criteria. Genetic analysis of rs10741657 of CYP2R1 including primer designing, DNA extraction, PCR of target region with purification and Sanger sequencing of the PCR products were done accordingly. For statistical analysis, One-way ANOVA followed by LSD test, Freeman-Halton extension of Fisher’s exact test, Chi-square test (χ2) test and unpaired student t-test were performed. Results In this study, genetic variants of CYP2R1 (rs10741657) among the study population were genotype GG (63.30%), GA (30%) and AA (6.7%). Minor allele frequency of the study population was 0.217. The association between GG and GA genotypes of CYP2R1 (rs10741657) with low serum 25(OH)D level among the study population was found and it was statistically significant. Statistically significant differences were also observed between the genotypes and alleles of the study population and controls. Conclusions The presence of ‘GG’ and ‘GA’ genotypes of rs1041657 in CYP2R1 gene is associated with low serum 25(OH)D level among Bangladeshi adults in this pilot study.

Background and objectives: The prevalence of anxiety disorders is increasing in the world. Studies revealed that generalized anxiety disorder may lead to change in circulating catecholamine levels. Thus, the changes of catecholamine metabolite like urinary vanillylmandelic acid may increase the future risk of thrombotic diseases in patients with generalized anxiety disorder (GAD). The aim of this present study is to evaluate urinary vanillylmandelic acid (VMA) levels in patients with generalized anxiety disorder. Materials and methods: A cross-sectional study was performed in the Department of Physiology, Dhaka Medical College, Dhaka from July 2019 to June 2020.After obtaining ethical clearance, a total 144 individuals were selected based on inclusion and exclusion criteria with age ranging from 18-50 years. Group A was study group selected from Out Patient Department of Psychiatry of Dhaka Medical College Hospital, Dhaka diagnosed by the experienced psychiatrist. Group B was control group who were apparently healthy adults selected from different area of Dhaka city. The subjects were interviewed and detailed history regarding personal, family, medical and drug history were taken. Prior to sample collection, informed written consent was taken from the participants. Urinary vanillylmandelic acid levels were measured in the Department of Endocrinology, BIRDEM General Hospital, Dhaka. Statistical analysis: For statistical analysis, Unpaired Student’s ‘t’ test was considered using SPSS 25.0 version. Results: Urinary vanillylmandelic acid of generalized anxiety disorder patients was significantly higher (p< 0.001) than control group. Conclusion: It can be concluded that generalized anxiety disorder patients may have more chance of thrombotic diseases due to significantly higher urinary vanillylmandelic acid (VMA) levels than healthy adults.

Background: The prevalence of anxiety disorders is increasing in the world. Studies revealed that generalized anxiety disorder may lead to change in platelet size, volume and functions. Thus, the changes in platelet indices may increase the future risk of thrombotic diseases in patients with Generalized Anxiety Disorder (GAD). Aim: To evaluate platelet indices (total count of platelet, mean platelet volume, platelet distribution width, plateletcrit) levels in patients with generalized anxiety disorder. Material and Methods: A cross-sectional study was performed in the Department of Physiology, Dhaka Medical College, Dhaka from July 2019 to June 2020. After obtaining ethical clearance, a total of 144 individuals were selected based on inclusion and exclusion criteria with ages ranging from 18 -50 years. Group A was the study group selected from Out Patient Department of Psychiatry of Dhaka Medical College Hospital, Dhaka, diagnosed by an experienced psychiatrist.

Background: ABO blood group distribution defers with racial and geographic variations. They are related to diseases like cardiovascular diseases, cerebral thromboembolism. ABO blood group system may influence coagulation factor VIII which may increase the future risk of thrombosis. Aim: To assess the relation of ABO blood group with coagulation factor VIII in healthy adults. Material and Methods: A prospective type of analytical cross-sectional study was conducted in the Department of Physiology, Dhaka Medical College, Dhaka from July 2019 to June 2020. After obtaining ethical clearance, a total of 190 healthy adults were selected from different areas of Dhaka city based on inclusion and exclusion criteria, with ages ranging from 18 -45 years. The subjects were interviewed and detailed history regarding personal, family, medical and drug were taken. Prior to sample collection, informed written consent was taken from the participants. Individuals of blood group A were selected as group A, blood group B as group B, blood group AB as group AB and blood group O as group O.
