    Abstract COVID 19 is caused by Severe Acute Respiratory Syndrome Corona Virus-2 which results in wide range of manifestations. Systemic hypercoagulation is a typical feature of COVID-19. We present a case of COVID-19 in whom TEG was performed on admission and hypercoagulability was diagnosed and hence patient was started on Enoxaparin sodium 6000 IU twice daily. TEG was repeated after 5 days which showed normal coagulation status and the patient was discharged without any thrombotic complications.

    Abstract Objectives: Adverse donor reactions (ADR) may often go unreported due to donor related or blood center related factors. Possible donor related factors are self-ignorance of the adverse reaction, inertia to notify blood centre and non-compliance to follow-up. A better understanding of the self-ignored adverse donor reaction (SIADR) helps in early detection, avoidance of complications, adoption of mitigation strategies, and retention of donors. In the current study, we aim to identify the incidence and reasons for onsite SIADR among whole blood donors.
    Materials and methods: Prospective single-center observational study where 501 participants who completed whole blood donation were recruited. They were interviewed twice by an experienced investigator to identify any onsite SIADR occurred. First interview was conducted just before leaving the premise and second two days after donation using a peer reviewed and validated questionnaire. Cross-tabulation and Chi-square test were used for bivariate analysis.
    Results: Twelve participants out of 501 (2.39%) were found to have onsite SIADR which was twice the frequency of reported onsite ADR (1.20%) during the study period in our center. A majority (75%) of them experienced grade I vaso-vagal reactions (VVR). Around 58.3% of the SIADR donors ignored the reaction as they perceived it as mild, while 25% perceived the symptoms but failed to interpret them as a reaction.
    Conclusion: In our center, incidence of onsite SIADR was double the incidence of ADR and majority were VVR grade I. Commonest reason for SIADR was interpretation of reaction as mild. Blood center team shall be proactive and vigilant to identify and report SIADR.

    Abstract Unmanageable bleeding is one of the significant causes of mortality. Attaining rapid hemostasis ensures subject survivability as a first aid during combats, road accidents, surgeries that reduce mortality. Nanoporous fibers reinforced composite scaffold (NFRCS) developed by a simple hemostatic film-forming composition (HFFC) (as a continuous phase) can trigger and intensify hemostasis. NFRCS developed was based on the dragonfly wing structure's structural design. Dragonfly wing structure consists of cross-veins and longitudinal wing veins inter-connected with wing membrane to maintain the microstructural integrity. The HFFC uniformly surface coats the fibers with nano thickness film and interconnects the randomly distributed cotton gauge (Ct) (dispersed phase), resulting in the formation of a nanoporous structure. Integrating continuous and dispersed phases reduce the product cost by ten times that of marketed products. The modified NFRCS (tampon or wrist band) can be used for various biomedical applications. The in vivo studies conclude that the developed Cp NFRCS triggers and intensifies the coagulation process at the application site. The NFRCS could regulate the microenvironment and act at the cellular level due to its nanoporous structure, which resulted in better wound healing in the excision wound model.

    Abstract Background: COVID-19 associated coagulopathy (CAC) can either be localized or systemic hypercoagulable state with increased risk of thromboembolism. This study looked into the usefulness of Thromboelastography (TEG) and the velocity curve (V-curve) derivative from TEG in diagnosing and differentiating different stages of CAC.
    Materials and methods: A prospective single cohort study of RT-PCR confirmed COVID-19 patients was carried out for 2 weeks. Severe COVID-19 patients in the adult critical care units with a TEG report were recruited for the study. Citrated kaolin TEG was performed on the day of admission before anticoagulation. TEG parameters included were R and K time, alpha angle, maximum amplitude, clotting index, lysis at 30 min. The first-degree velocity curve of TEG is plotted as V-curve which extrapolates thrombus generation potential. Parameters analyzed were the maximum rate of thrombus generation as well as thrombus generated (TG).
    Results: The study included 43 patients with an average age of 58.34 (±15.35). TEG as well as V-curve of all the patients were hypercoagulable compared with age-matched reference range. We had 79.06% of patients in hypercoagulable stage. The mortality rate was 32.56% and 30.23% developed thrombotic incidents. Patients who succumbed to death had prolonged PT, aPTT, MA, Ly30, with a reduced TG (p < .05). The presence of fibrinolysis was associated with thromboembolism (OR = 6.76, CI = 1.48-25.82). Repeat TEG was done randomly in 11 patients and revealed a persistent hypercoagulable stage with increasing fibrinolysis activity.
    Conclusion: TEG is a useful tool in diagnosing and categorizing Coagulopathy associated with COVID-19.
