Retrospective comparison between non-treponemal and treponemal tests for screening of blood donors for syphilis and their correlation with donor history in a tertiary care teaching hospital.

BACKGROUND AND OBJECTIVES: Treponemal tests provide advantage of better detection during early, late and latent stages of syphilis with equal or higher sensitivity & specificity in comparison to non-treponemal tests. The objective of the present study was to analyse the level of concordance between treponemal and non-treponemal tests for donor screening and to correlate them with donor history. MATERIALS AND METHODS: Retrospective analysis of syphilis screening by treponemal (Chemiluminescence & TPHA) and non-treponemal tests (RPR) was done and donor history for high-risk behaviour and factors associated with false positivity were collected from post-donation counselling and collected data was coded and analysed. RESULTS: Amongst the 12,000 donors screened, reactivity rate by RPR, TPHA and Chemiluminescence was 0.45%, 0.8% and 1.17% respectively. There was discordance of 62% and 32% for reactive results by RPR and TPHA respectively when compared with Chemiluminescence. History of high-risk behaviour was present in ∼ 50% and 15% of donors with discordant results by RPR and TPHA respectively. Of 34 donors who were reactive only by Chemiluminescence and were followed up, 15% had history of high-risk behaviour and 56% had factors associated with false reactivity. CONCLUSION: Treponemal tests showed high syphilis reactivity amongst blood donors as compared to non-treponemal tests most likely due to their ability to detect early, late and latent syphilis cases. This may confer added transfusion safety in centres dependent on replacement donors without NAT testing by identifying donors with high-risk history with negligible increase in discard rate due to false reactivity.

Is coronavirus lockdown taking a toll on mental health of medical students? A study using WHOQOL-BREF questionnaire.

INTRODUCTION: The Quality of life is a broad-ranging concept affected in a complex way by the person's physical health, psychological state, level of independence, social relationships, personal beliefs, and their relationship to salient features of their environment. The ongoing COVID-19 pandemic has resulted in many quarantine and isolation measures and lockdown of the nation for the foreseeable future. Although these initiatives are necessary to prevent the spread of coronavirus they may be causing adverse mental health effects. Medical students are backbone and future of the health system and the general public always looks up to them as a role model of society. With this background, this study aims to assess the quality of life among medical students during the lockdown period amid the COVID-19 pandemic. MATERIAL AND METHODS: A self-administered, pretested, questionnaire based on World Health Organization Quality of Life: Brief Version (WHOQOL-BREF) standard quality of life was used. For internal reliability and structural validity, Cronbach's alpha coefficient and confirmatory factor analysis (CFA) were calculated, respectively. t-test, one way ANOVA, and Pearson Chi-square test were used. RESULTS: The mean scores of domains of the present study were highest for the environmental domain (72.10 ± 13.0) followed by physical (67.23 ± 13.74), social (57.13 ± 20.1), and lowest for the psychological domain (52.10 ± 17.45). The level of internal consistency was found to be 0.883, which is considered as sufficiently reliable. One-third of the medical students were spending >6 h on-screen, and merely 15.6% were doing physical activity >1 h. CONCLUSION: It was found that during this time of crisis medical students were weaker in the psychological domain of Quality of Life among all the four domains. Physical activity and screen time was an important factor to the QOL of students, and it is likely that students would benefit from increased physical activity and minimizing screen time.
