    Background: Hemoglobinopathies pose a significant health burden in India. Prevention programmes can significantly reduce this burden. Although sophisticated methods of screening for β thalassemia trait are available, a cheap and simple method is beneficial for population screening. Although the Naked Eye Single Tube Red Cell Osmotic Fragility Test (NESTROFT) has been evaluated in many studies, sample sizes were small in some and many earlier studies have not done complete blood count (CBC) and High-Performance Liquid Chromatography (HPLC) in all the cases. We evaluate the suitability of NESTROFT for detection of β-thalassemia trait in a high prevalence region in Saurashtra, Gujarat.Methods: Here, 1000 unrelated individuals were studied. NESTROFT, CBC and estimation of HbA2 and HbF or other hemoglobin variants were done by HPLC.Results: Prevalence of β thalassemia trait was 7.8% in this population. NESTROFT showed an overall sensitivity and specificity of 94.87 and 85.38 respectively for the detection of β thalassaemia trait. Using red cell indices (MCH <27 pg and MCV <80 fl), One β thalassemia trait with normal indices would have been missed. Among twelve individuals with other hemoglobinopathies (HbS, HbD, HbE, δβ thalassemia trait or HPFH), seven had a positive NESTROFT while three had normal MCV & MCH values.Conclusions: NESTROFT is a cost-effective sensitive test which does not require any equipment and can be done in remote areas. It remains a useful first line screening test when large populations have to be screened.

    Nebulized Recombinant Tissue Plasminogen Activator (rt-PA) for Acute COVID-19-Induced Respiratory Failure: An Exploratory Proof-of-Concept Trial

    Acute lung injury in COVID-19 results in diffuse alveolar damage with disruption of the alveolar-capillary barrier, coagulation activation, alveolar fibrin deposition and pulmonary capillary thrombi. Nebulized recombinant tissue plasminogen activator (rt-PA) has the potential to facilitate localized thrombolysis in the alveolar compartment and improve oxygenation. In this proof-of-concept safety study, adults with COVID-19-induced respiratory failure and a <300 mmHg PaO2/FiO2 (P/F) ratio requiring invasive mechanical ventilation (IMV) or non-invasive respiratory support (NIRS) received nebulized rt-PA in two cohorts (C1 and C2), alongside standard of care, between 23 April–30 July 2020 and 21 January–19 February 2021, respectively. Matched historical controls (MHC; n = 18) were used in C1 to explore efficacy. Safety co-primary endpoints were treatment-related bleeds and <1.0–1.5 g/L fibrinogen reduction. A variable dosing strategy with clinical efficacy endpoint and minimal safety concerns was determined in C1 for use in C2; patients were stratified by ventilation type to receive 40–60 mg rt-PA daily for ≤14 days. Nine patients in C1 (IMV, 6/9; NIRS, 3/9) and 26 in C2 (IMV, 12/26; NIRS, 14/26) received nebulized rt-PA for a mean (SD) of 6.7 (4.6) and 9.1(4.6) days, respectively. Four bleeds (one severe, three mild) in three patients were considered treatment related. There were no significant fibrinogen reductions. Greater improvements in mean P/F ratio from baseline to study end were observed in C1 compared with MHC (C1; 154 to 299 vs. MHC; 154 to 212). In C2, there was no difference in the baseline P/F ratio of NIRS and IMV patients. However, a larger improvement in the P/F ratio occurred in NIRS patients (NIRS; 126 to 240 vs. IMV; 120 to 188) and fewer treatment days were required (NIRS; 7.86 vs. IMV; 10.5). Nebulized rt-PA appears to be well-tolerated, with a trend towards improved oxygenation, particularly in the NIRS group. Randomized clinical trials are required to demonstrate the clinical effect significance and magnitude

    Acknowledgments We would like to extend our sincerest gratitude to all the colleagues and hospital staff who worked tirelessly throughout the pandemic and without whom this work would not have been possible. Firstly, we would like to thank our colleagues in the intensive care unit (ICU), in particular the matrons, Sean Carroll and Sinead Hanton, and research nurses, Filipe Helder and Amitaa Maharajh for their support, and bedside nurses who bore the responsibility of drug administration. We would also like to extend our thanks to ICU consultants who acted as professional legal consultees on behalf of critical care patients. Equally, we would like to thank colleagues within the respiratory team. Their expertise was instrumental to our role in treating patients on 8N and 8E wards. A special mention to lead Nurse Mary Emerson; we were grateful for her knowledge, support and for facilitating the training for the nebulizer and drug administration on the wards. We would like to thank Aarti Nandani and all the staff in the Royal Free clinical trials pharmacy for their immense support throughout the whole pandemic, especially considering their ever-increasing workload at the time. Thanks also to the HSL coagulation laboratory, the Trust R&D department and all the staff working to cover during a very challenging time. We are also very grateful to the Royal Free charity for funding this study. Finally, we would like to thank all the clinical nurses, physiotherapists, research data managers and healthcare professionals within the Haemophilia department (and wider hospital) for all their many efforts in supporting this study. This trial was overseen by an independent data monitoring committee, chaired by Najib Rahman, Director of the Oxford Respiratory Trials Unit, University of Oxford and comprises the following committee members: Mike Makris, Jonathan Silversides and Henry Watson. Funding Royal Free Charity Trust Fund 35 provided funding for this study. The study drug was provided by Boehringer Ingelheim (BI). BI had no role in the design, analysis, or interpretation of the results. They were given the opportunity to review the manuscript for medical and scientific accuracy since it relates to BI substances and intellectual property considerations.Peer reviewedPublisher PD

    From the sinh-Gordon field theory to the one-dimensional Bose gas: exact local correlations and full counting statistics

    Get PDF
    We derive exact formulas for the expectation value of local observables in a one-dimensional gas of bosons with point-wise repulsive interactions (Lieb-Liniger model). Starting from a recently conjectured expression for the expectation value of vertex operators in the sinh-Gordon field theory, we derive explicit analytic expressions for the one-point K-body correlation functions \u27e8(\u3a8\u2020)K(\u3a8)K\u27e9 in the Lieb-Liniger gas, for arbitrary integer K. These are valid for all excited states in the thermodynamic limit, including thermal states, generalized Gibbs ensembles and non-equilibrium steady states arising in transport settings. Our formulas display several physically interesting applications: most prominently, they allow us to compute the full counting statistics for the particle-number fluctuations in a short interval. Furthermore, combining our findings with the recently introduced generalized hydrodynamics, we are able to study multi-point correlation functions at the Eulerian scale in non-homogeneous settings. Our results complement previous studies in the literature and provide a full solution to the problem of computing one-point functions in the Lieb Liniger model

    Dimethyl fumarate (DMF) inhibits inflammasome-mediated inflammation and has been proposed as a treatment for patients hospitalised with COVID-19. This randomised, controlled, open-label platform trial (Randomised Evaluation of COVID-19 Therapy [RECOVERY]), is assessing multiple treatments in patients hospitalised for COVID-19 (NCT04381936, ISRCTN50189673). In this assessment of DMF performed at 27 UK hospitals, adults were randomly allocated (1:1) to either usual standard of care alone or usual standard of care plus DMF. The primary outcome was clinical status on day 5 measured on a seven-point ordinal scale. Secondary outcomes were time to sustained improvement in clinical status, time to discharge, day 5 peripheral blood oxygenation, day 5 C-reactive protein, and improvement in day 10 clinical status. Between 2 March 2021 and 18 November 2021, 713 patients were enroled in the DMF evaluation, of whom 356 were randomly allocated to receive usual care plus DMF, and 357 to usual care alone. 95% of patients received corticosteroids as part of routine care. There was no evidence of a beneficial effect of DMF on clinical status at day 5 (common odds ratio of unfavourable outcome 1.12; 95% CI 0.86-1.47; p = 0.40). There was no significant effect of DMF on any secondary outcome
