    We analyze the dynamics of cervical cancer mortality rates for African American and White women residing in 13 states located in the eastern half of the United States of America from 1975 through 2010. Despite decreasing trends in cervical cancer mortality rates for both races, racial disparities in mortality rates still exist. In all 13 states, Black women had higher mortality rates at all times. The degree of disparities and pace of decline in mortality rates over time differed among these states. In all 13 states, cervical cancer mortality rates for both racial groups have fallen. Disparities in the pace of decline in mortality rates in these states may be due to differences in the rates of screening for cervical cancers. Of note, the gap in cervical cancer mortality rates between Black women and White women is narrowing

    Impact of Inconsistent Policies for Transfusion-Transmitted Malaria on Clinical Practice in Ghana

    Background: Policies concerning the prevention of transfusion transmitted malaria (TTM) are the responsibility of blood transfusion services and malaria control programmes. To prevent spreading drug resistance due to over-use of malaria drugs, recent malaria treatment guidelines recommend prompt parasitological confirmation before treatment is started. In contrast, blood safety policies from the World Health Organisation (WHO) recommend presumptive malaria treatment for recipients of blood in endemic countries but evidence supporting this approach is lacking. Our study documented how these conflicting policies relating to malaria transmission through blood transfusion impact on clinical practice in a teaching hospital in West Africa. Methods/Principal Findings: We randomly selected and reviewed case notes of 151 patients within 24 hours of their receiving a blood transfusion. Transfusion practices including the confirmation of diagnosis and anti-malarial treatment given were compared across three departments; Obstetrics and Gynaecology (O&G), Paediatrics and Medicine. Overall, 66 (44%) of patients received malaria treatment within 24 hrs of their blood transfusion; of which only 2 (3%) received antimalarials based on a laboratory confirmation of malaria. Paediatric patients (87%) received the most anti-malarials and only 7 % and 24 % of recipients in medicine and O&G respectively received anti malarials. In 51 patients (78%), the anti-malarials were prescribed at the same time as the blood transfusion and anti-malarials prescriptions exceeded the number of patient

    In order to prevent post transfusion alloimmunization, it is essential to give recipients compatible blood products. However in countries with limited income, blood grouping is limited to the ABO system and to the D antigen of the Rhesus system; however, there are other immunogenic antigens such as C, c, E, e and K to name a few. This should be the reason why a retrospective study by Tayou et al. at the blood bank of the University Hospital Center (CHU) of Yaoundé in 2009 on the erythrocyte phenotype in the donor and recipient of blood product only reported to us that data relate to the erythrocyte blood group system ABO and the Rh 1 antigen. We therefore found it expedient to carry out erythrocyte phenotyping in the ABO, RH and KELL blood group systems in the donor and recipient of blood products at the CHU of Yaoundé.&#x0D; A descriptive, transversal and prospective study was carried out at the blood bank of the CHU of Yaoundé over 6 months, from June 1, 2017 to December 31, 2017. It was interested in the donor-recipient couples of blood within which the recipient was a patient hospitalized at the CHU. Laboratory analyses of donor and recipient blood samples have allowed us to have the phenotypes in the ABO, RH, and KELL blood group systems.&#x0D; In the ABO system, the phenotypes obtained were 4: A1, A1B, B and O at 27.27%, 2.27%, 13.64% and 56.82% respectively among donors and 31.82%, 2.27%, 13.64% and 52.27% among recipients. In addition, from the Rhesus system, there were 5 phenotypes in donors: D + C + E + c + e +, D + C + E-c + e +, D + C-E + c + e +, D + CE-c + e +, DCE-c + e + respectively at 2.27%, 11.36%, 9.09%, 75.00% and 2.27% and in recipients 4 phenotypes, namely: D + C + E + c + e +, D + C-E + c + e +, D + CE-c + e +, DCE-c + e + at 15.91%, 27.27%, 54.55% and 2.27% respectively. In the KELL system, the K antigen was present in 4.55% of donors and 2.27% of recipients. An antigen supply from the donor to the recipient was evaluated at 6.82% for C, 4.54% for E, 2.27% for K and 2.27% for K, C, E at the same time. This gave us an estimate of the average risk of alloimmunization at 15.9%.&#x0D; Erythrocyte phenotyping would therefore be of major benefit during blood transfusion and would considerably prevent the risks of alloimmunization.</jats:p
