Item Development Of Hplc Method For Stress Testing Of Combination Of Two Drugs Using Design Of Experiment Concept(MRI Publication Pvt. Ltd., 2019-11) Bajaj, M.; Nanda, S.This study was conducted to develop, an High Performance Liquid Chromatography using photodiode array detector (HPLC-PDA) method to analyse the samples generated by the stress testing of antifilarial combination (albendazole and diethylcarbamazine citrate) in the solution state. The concept of Quality by Design (Design of Experiment, DoE) approach was used for the development. For the separation of the drugs and its degradation products (DPs), DoE was applied in two stages, i.e., primary parameter stage where factors having major effect were selected. This stage gives us CQA (Critical Quality Attribute) which along with minor factors affecting were varied to get the secondary design. For each of the stage a different design was selected; for primary stage IV optimal design (Response Surface Method) was selected whereas for secondary stage, Taguchi orthogonal array design was selected. The major primary parameters affecting the HPLC method as screened by preliminary studies were the buffer pH, organic modifier (methanol or acetonitrile), initial hold time (start of gradient) and gradient time. The primary stage was completed successfully. The results were compiled in form of resolution of peak from next peak and analysed by DoE. The process fixed the values for buffer pH (4.38), organic modifier (acetonitrile) and gradient time (30 min). The CQA from primary run was initial hold time. This parameter along with other parameters: initial and final concentration of organic modifier, buffer type (phosphate or acetate), buffer strength (mM) and oven temperature were further varied and samples withdrawn were analysed. The data of secondary design was compiled in the form of resolution (R), analysed by Design Expert and final value for secondary parameter for HPLC method were fixed. The resolution of the peaks for some secondary runs was sufficient reflecting some type of interaction between the drugs and/or degradation products.Item Health profile of security personnel in a tertiary care hospital in Odisha(Mrs Dipika Charan of MedScience (India) Publications, 2022-09) Patnaik, A; Dash, A; Samal, MR; Nanda, S.Background: Security guards/protective inspectors are a group of professional gray collar workers responsible for safety and security of general public. In healthcare institutions, they play a pivotal role in streamlining the movement of patients, healthcare workers as well as other people as well as keeping a check upon the law-breaking activities within the premises. These professionals are constantly overburdened with responsibility and many of them are under the verge of physical, mental, and emotional crisis leading to various health issues. Aim and Objective: To assess the influence of changing work patterns on the overall physical health of security guards working in the hospital. Materials and Methods: A cross-sectional study was carried out in a tertiary care hospital in the Eastern part of Odisha involving all the security personnel currently working. Universal sampling was opted and 465 personnel participated in this study. Results: Of the total, 213 (45.8%) were between 30 and 40 years of age and 398 (85.5%) were male. 179 (38.4%) were overweight and 52.2% had a waist-hip ratio above normal range for their gender. Prevalence of anemia and Conjunctival xerosis was significantly higher among night shift workers with P < 0.001 whereas hypertension (P = 0.08) and rheumatoid arthritis (P = 0.006) was significantly higher among morning shift workers. Conclusion: Being a distinctive member of the hospital, it is high time that regular health check-ups and social security measures should be made available to them in order to provide quality life which will in turn ensure better hospital safety and security.
