Abstract: that her persistent thrombocytopenia was caused by sepsis, not refractory TTP. In Patient 10, TTP was unresponsive to multiple treatments, in addition to PEX, corticosteroids, and rituximab. Plus, ADAMTS13 activity was not measured during her… read more here.

DOI: 10.1002/ajh.26356
Abstract: To the Editor: Low oxygen affinity hemoglobin (Hb) mutations are a rare but important consideration in patients presenting with low peripheral oxygen saturations (SpO2) and anemia without clinical evidence of hypoxia; cyanosis may also be… read more here.

DOI: 10.1080/03630269.2017.1302467
Abstract: Abstract We describe an insertion variant on the α1-globin gene (HBA1) identified in a 49-year-old woman of Jurassian ancestry presenting with macrocytosis and erythrocytosis. The variant resulted in a peak of 15.5% of the total… read more here.

DOI: 10.1111/bjh.16888
Abstract: Abstract During critical care, at least until the late stage of the disease, severely ill COVID‐19 patients may have relatively well preserved lung compliance but remain severely hypoxaemic. A recent theoretical study suggested a direct… read more here.

DOI: 10.3389/fphys.2021.763933
Abstract: Humans elicit a robust series of physiological responses to maintain adequate oxygen delivery during hypoxia, including a transient reduction in hemoglobin-oxygen (Hb-O2) affinity. However, high Hb-O2 affinity has been identified as a beneficial adaptation in… read more here.
