The blood components obtained from apheresis offer greater safety to patients at the time of blood transfusion; verifying leukoreduction differentiator Material and Methods: A descriptive study was performed cross-sectional in Colombia Hematol\'{o}gica Foundation. Bogot\'{a}. Simple random sampling was performed from the list entered in a blood drive for the purpose of verification of residual white blood cell count by Nageotte chamber and Cell Dyn Ruby © © units. For the analysis of the data measures of central tendency and dispersion for quantitative variables were applied (95%) and Spearman correlation analysis for satisfactory procedures (t-test); Data analysis was performed on SPSS Version IBM © program 19. Results: The study population consisted of 124 samples of platelets obtained by apheresis. In relation to cell count for the two methodologies presented an average of 0,057 vs 0,003 cells counted; the maximum value for the two methods was 0.34 to 0.44. Conclusions: The samples analyzed presented residual white blood cell counts below 5.0 x 106 estimated to set the drive as leukoreduced with this finding value puts the safety of transfused platelets obtained by apheresis aspects reactions to evidence transfusion rWBC additionally could be used safely leaving platelets into consideration the use of filters to leucorreduci\'{o}n.},

abstract = {Objective: To determine the seroprevalence of HTLV screening and factors associated with co-infection in blood donors in Colombia. 



Materials and Methods: We performed a retrospective cross-sectional study inferential, the population was of 971 records of volunteer blood donors, we calculated the prevalence of HTLV and calculated odds ratios (OR). 



Results: 49.3 % of donors were between 18 and 33 years, 53.4 % were female, 44.3 % lived with a partner, it was observed that the major syphilis coinfections are 7.0 %. There is a trend to increased prevalence of HTLV between 2010 (0.23 %) and 2011 (0.24 %) in the process of Bogot\'{a}. Headquarters in related factors associated, a positive association was found with increasing age and living with a partner, and negative association with the contributory system in multiple Poisson regression showed that the prevalence of co-infection is 2.92 (95 % CI 1.92 to 4.45) times in people 34 to 64 years compared to under 34 years, also the contributory scheme protects coinfection 0.69 (95 % CI 0.48-0.99) in people with contributory scheme compared to the subsidized regime. 



Conclusi\'{o}n: In general there is a significant proportion of donors with reactive results are set out clearly and factors associated with coinfection prevalence is higher than in other reports.

abstract = {Objective: To establish the prevalence of hepatitis B and C and factors related to coinfection with other markers screened in blood bank volunteer donors between 2006 and 2011 in a blood bank in Colombia. 



Methods: A retrospective cross-sectional study. The study population consisted of 587.446 records of volunteer blood donors, of which 13.133 showed reactivity to hepatitis B and/or hepatitis C; odds ratios were calculated to establish factors associated with coinfection. 



Results: The mean age was 38.55 ± 12.4. The odds ratios for simultaneous coinfection with other blood bank markers and analyzed variables were membership scheme 1.1 (1.04 to 1.36), gender 1,4 (1.22 \textendash 1.61), and age 4.2 (3.54 to 4.99) for hepatitis B, and age 0.6 (0.38-1.00) and gender 5.1 (3.07-8.78) for hepatitis C.



Conclusions: This study demonstrates that age is a risk factor for simultaneous reactivity with other screening markers in blood banks. A different behavior was found between gender according to existing coinfection studies. },

Materials and methods: We performed a cross-type study with professors of physical therapy program at the University of Santander \textendash Colombia in 2013.

Results: The study population consisted of 21 professors in the physical therapy program with an average age of 37.05 years, the majority was female, the teaching experience was 9.20 years, and only 23.8% of professors had donated blood at some time in their life. Regarding the promotion of donation in classrooms, the donation was considered important by all professors. Among the reasons for not donating blood, “Scared of having your blood drawn” was the most important, and among reasons for donating, the main one was advertising.

Discussion: Professors are important actors in the process of promoting blood donation in the student population.},

abstract = {The demand for blood donation makes it a constant activity, whereby knowing the motivational aspects for its implementation becomes a determinant in the formulation of strategies for the increase of donors and to strengthen the donation programs. The aim of this study was to establish the main motivations for voluntary donation in the population that attended a gathering point of Bogot\'{a} (Colombia). A descriptive transversal study was designed with a sample of 500 adults (28.8 ± 10.4 years), 58% female. A survey was done for data collection. The variables used were age, sex, socioeconomic status, residence for the last five years and the main motive for blood donating. A descriptive and a bivariate analysis applying the chi2 test were executed. The software used was Stata 11.0. The main motives for the donation were the promotion (18% CI 95% 14.7-21.7) and to save lives (14.4% CI 95% 11.4-17.8). People coming from socioeconomic levels I and II donated mainly motivated by the promotion (33.0%) and those from the socioeconomic levels III, IV and V donated mainly to save lives (38.4%). The interviewed population gave clear information about the aspects that motivated voluntarily and willingly blood donation, as to promote more donations and save lives, among others.},

Objective: establish the main social preconceptions related to the voluntary donation of blood. Methods: a descriptive transversal study of a sample of 100 adults. The data was gathered through the application of surveys conducted during the months of July to December of 2010. The variables were: age, sex, origin, social and financial status, level of education and main preconceptions related to the donation of blood. A descriptive analysis was conducted; the software used was Epilnfo version 3.5.1. Results: the main preconception for women was "gaining weight" with 70.59%, while for men it was "blood is commercialized" with 36.36%. Discussion: the age described in the study and the social and cultural aspects behave according to those predetermined; the social preconceptions are established mainly by the feminine gender with the weight increase. Conclusion: the social preconceptions allow for the subjects to have a greater negative predisposition towards donating blood.},
