Journal ArticleDOI
Exploring mechanisms of excess mortality with early fluid resuscitation: insights from the FEAST trial
Kathryn Maitland,Elizabeth C George,Jennifer Evans,Sarah Kiguli,Peter Olupot-Olupot,Samuel Akech,Robert O. Opoka,Charles Engoru,Richard Nyeko,George Mtove,Hugh Reyburn,Bernadette Brent,Julius Nteziyaremye,Ayub Mpoya,Natalie Prevatt,Cornelius M Dambisya,Daniel Semakula,Ahmed Ddungu,Vicent Okuuny,Ronald Wokulira,Molline Timbwa,Benedict Otii,Michael Levin,Jane Crawley,Abdel Babiker,Diana M. Gibb +25 more
TL;DR: Excess mortality from boluses occurred in all subgroups of children and should prompt a re-evaluation of evidence on fluid resuscitation for shock and are-appraisal of the rate, composition and volume of resuscitation fluids.
Journal ArticleDOI
Predicting mortality in sick African children: the FEAST Paediatric Emergency Triage (PET) Score
Elizabeth C George,AS Walker,Sarah Kiguli,Peter Olupot-Olupot,Robert O. Opoka,Charles Engoru,Samuel Akech,Richard Nyeko,George Mtove,Hugh Reyburn,James A. Berkley,Ayub Mpoya,Michael Levin,Jane Crawley,Jane Crawley,Diana M. Gibb,Kathryn Maitland,Kathryn Maitland,Abdel Babiker +18 more
TL;DR: Eight clinical prognostic factors that could be rapidly assessed by healthcare staff for triage were combined to create the FEAST Paediatric Emergency Triage (PET) score and externally validated and discriminated those at highest risk of fatal outcome at the point of hospital admission and compared well to other published risk scores.
Journal ArticleDOI
Immediate Transfusion in African Children with Uncomplicated Severe Anemia
Kathryn Maitland,Sarah Kiguli,Peter Olupot-Olupot,Charles Engoru,Macpherson Mallewa,Pedro Saramago Goncalves,Robert O. Opoka,Ayub Mpoya,Florence Alaroker,Julius Nteziyaremye,George Chagaluka,Neil Kennedy,Eva Nabawanuka,Margaret Nakuya,Cate Namayanja,Sophie Uyoga,Dorothy Kyeyune Byabazaire,Bridon M'baya,Benjamin Wabwire,Gary Frost,Imelda Bates,Jennifer Evans,Thomas N. Williams,Elizabeth C George,Diana M. Gibb,A. Sarah Walker +25 more
TL;DR: There was no evidence of differences in clinical outcomes over 6 months between the children who received immediate transfusion and those who did not, and the triggered-transfusion strategy in the control group resulted in lower blood use; however, the length of hospital stay was longer, and this strategy required clinical and hemoglobin monitoring.
Journal ArticleDOI
Transfusion and Treatment of severe anaemia in African children (TRACT): a study protocol for a randomised controlled trial
Ayub Mpoya,Sarah Kiguli,Peter Olupot-Olupot,Robert O. Opoka,Charles Engoru,Macpherson Mallewa,Yami Chimalizeni,Neil Kennedy,Dorothy Kyeyune,Benjamin Wabwire,Bridon M'baya,Imelda Bates,Imelda Bates,Britta C. Urban,Britta C. Urban,Michael Boele von Hensbroek,Robert S. Heyderman,Robert S. Heyderman,Margaret J. Thomason,Sophie Uyoga,Thomas N. Williams,Diana M. Gibb,Elizabeth C. George,A. Sarah Walker,Kathryn Maitland +24 more
TL;DR: If confirmed by the trial, a cheap and widely available ‘bundle’ of effective interventions, directed at immediate and downstream consequences of severe anaemia, could lead to substantial reductions in mortality in a substantial number of African children hospitalised withsevere anaemia every year, if widely implemented.
Journal ArticleDOI
Transfusion Volume for Children with Severe Anemia in Africa
Kathryn Maitland,Peter Olupot-Olupot,Sarah Kiguli,George Chagaluka,Florence Alaroker,Robert O. Opoka,Ayub Mpoya,Charles Engoru,Julius Nteziyaremye,Macpherson Mallewa,Neil Kennedy,Margaret Nakuya,Cate Namayanja,Julianna Kayaga,Sophie Uyoga,Dorothy Kyeyune Byabazaire,Bridon M'baya,Benjamin Wabwire,Gary Frost,Imelda Bates,Jennifer Evans,Thomas N. Williams,Pedro Saramago Goncalves,Elizabeth C George,Diana M. Gibb,A. Sarah Walker +25 more
TL;DR: Overall mortality did not differ between the two transfusion strategies, and there was no evidence of differences between the randomized groups in readmissions, serious adverse events, or hemoglobin recovery at 180 days.
