Babesiosis is usually acquired from a tick bite or through a blood transfusion. We report a case of babesiosis in an infant for whom vertical transmission was suggested by evidence of Babesia spp. antibodies in the heel-stick blood sample and confirmed by detection of Babesia spp. DNA in placenta tissue.

Arterial dysfunction has been documented in patients with beta-thalassaemia major. This study aimed to determine the quantity and proliferative capacity of circulating CD133(+)VEGFR2(+) and CD34(+)VEGFR2(+) cells in patients with beta-thalassaemia major and those after haematopoietic stem cell transplantation (HSCT), and their relationships with arterial function. Brachial arterial flow-mediated dilation (FMD), carotid arterial stiffness, the quantity of these circulating cells and their number of colony-forming units (CFUs) were determined in 17 transfusion-dependent thalassaemia patients, 14 patients after HSCT and 11 controls. Compared with controls, both patient groups had significantly lower FMD and greater arterial stiffness. Despite having increased CD133(+)VEGFR2(+) and CD34(+)VEGFR2(+) cells, transfusion-dependent patients had significantly reduced CFUs compared with controls (p = 0.002). There was a trend of increasing CFUs across the three groups with decreasing iron load (p = 0.011). The CFUs correlated with brachial FMD (p = 0.029) and arterial stiffness (p = 0.02), but not with serum ferritin level. Multiple linear regression showed that CFU was a significant determinant of FMD (p = 0.043) and arterial stiffness (p = 0.02) after adjustment of age, sex, body mass index, blood pressure and serum ferritin level. In conclusion, arterial dysfunction found in patients with beta-thalassaemia major before and after HSCT may be related to impaired proliferation of CD133(+)VEGFR2(+) and CD34(+)VEGFR2(+) cells.

Goals Of Work: We report the first analysis of demographic, socioeconomic, and toxicity data from the Longitudinal Oncology Registry of Head and Neck Carcinoma (LORHAN).Materials and Methods: Eligible patients include newly diagnosed Head and Neck Cancer (HNC) patients, scheduled to receive radiotherapy or drug therapy, > or =18 years of age, and able to provide informed consent. Assessments are completed at baseline, at the completion of therapy, and yearly thereafter. Patient data are entered in the registry electronically and transferred via Secure HTTP protocols.Results: Reported use of supportive care differed by treatment setting. When compared to community sites, patients at academic centers received more supportive interventions: feeding tube (59% vs. 48%; p = 0.001), tracheotomy tube (16% vs. 9%; p = 0.002), opioid analgesics (89% vs. 59%; p < 0.0001), anti-emetics (83% vs. 68%; p < 0.0001), and amifostine (17% vs. 12%; p = 0.02). Reported grades 3-4 mucositis/stomatitis was also higher in patients treated at academic centers (38% vs. 28%; p = 0.001).Conclusion: There was a marked decrease in the documented use of supportive care measures in the community setting. This may be due to (1) lower rates of toxicity requiring less supportive care, (2) less stringent documentation, or (3) less aggressive use of supportive care measures. The documented rate of mucositis was less than expected. This is likely due to inadequate assessment or documentation. Further exploration of these findings is warranted as they may indicate an under appreciation and undertreatment of clinically significant acute tumor and treatment-related toxicities.
