Blood donor questionnaires and infectious disease screening in Latin American countries.

BACKGROUND AND OBJECTIVES: Blood donor questionnaires are tools used to screen prospective blood donors to determine their eligibility. There are limited data regarding blood donor questionnaires and infectious disease screening of the blood supply in Latin American countries. This study aimed to survey donor centres in Latin American countries to learn more about blood donor screening and infection assessment. MATERIALS AND METHODS: An international team of transfusion medicine professionals including medical directors and supervisors who work or collaborate with Latin American donor centres, called 'Comité de Investigación en Medicina Transfusional', designed a survey (16 questions) to characterize blood donor eligibility in Latin America. RESULTS: Eighty-two institutions from 14 Latin American countries responded to the survey. Most donor centres (66%; 54 of 82) had a donor deferral percentage between 5% and 25%, and the most common causes of deferrals were low haemoglobin and high-risk behaviour. Most donors in blood centres were directed family donors compared with voluntary donors. Infection evaluation included mostly serologic assessment (81%; 30 of 37) for human immunodeficiency virus (HIV), Hepatitis B, Hepatitis C, Treponema pallidum and Trypanosoma cruzi rather than nucleic acid tests (5%; 2 of 37). CONCLUSION: Heterogeneity exists in donor selection and infectious disease screening in Latin American countries. This survey provides valuable information to understand Latin American blood centre practices.

Successful Haploidentical Bone Marrow Transplantation of an Infant With a Novel Mutation in SAMD9L Gene (Ataxia-Pancytopenia Syndrome).

Data regarding the outcomes of hematopoietic stem cell transplant (HSCT) for the management of SAMD9L -associated ataxia-pancytopenia syndrome remains limited. We depict the case of a 2-month-old male with a novel mutation in the SAMD9L gene, presenting with respiratory failure, pancytopenia and severe developmental delay. He experienced graft failure 2 months after a 4/6 HLA-matched cord HSCT. At 9 months old, an unsuccessful unrelated donor search prompted a haploidentical HSCT with successful engraftment. He sustains excellent donor chimerism and has improved developmentally over 2 years posttransplant. This case demonstrates haploidentical HSCT as a viable option for patients with SAMD9L mutation and no acceptable unrelated donor.

Multisystem Inflammatory Syndrome in a Pediatric Patient With Sickle Cell Disease and COVID-19: A Case Report.

To this day, there are limited data about the effects and management of coronavirus disease infection in pediatric patients with sickle cell disease. We present the management and successful clinical course of an 8-year-old female with homozygous sickle cell disease (SS) and severe acute chest syndrome secondary to coronavirus disease 2019 infection, complicated by cortical vein thrombosis.

[The hand project: more hugs, no shakings]. / Proyecto manos: más abrazos, no sacudidas.

The purpose of the study was to determine if an educational program for parents of newborns can be useful to prevent Shaken Baby Syndrome in Puerto Rican families. Staff training was performed, parents observed an educational video & infant crying management strategies were discussed. Pre-post tests, follow up phone calls and medical chart reviews (53%) were conducted. A total of 65 newborns participated (62 mothers, 11 fathers). Parents reported that 50% had college studies, 78.7% lived together and 83.1% had government insurance. Pre-post tests demonstrated increase in knowledge (p < 0.05). Over 75% were contacted; 94% recalled learned strategies & 98% reported the infants had been well. Two infants were removed from home; no incidents of head trauma were reported. Almost half (44.5%) indicated taking care of the baby was difficult; managing the baby's crying was most difficult. All reported the program helped them. The program should be offered in other hospitals.
