Filter by:First developed in Zimbabwe, Club 25 is an initiative to promote blood donation among young people, who present a low-risk population for the spread of transfusion transmissible infections (TTIs). Club 25 members in Malawi make a pledge to donate blood 25 times during their lifetime. The primary aim of this study is to compare a Club 25 donation program to the current standard procedures for student blood donor recruitment in 30 secondary schools in Malawi. Roughly half of the schools will be randomly assigned to a Club 25 intervention and the study will collect data on student blood donations in all 30 schools for three school years. Upon completion of data collection the rate of student blood donation will be compared between the intervention schools and the non-intervention schools.
A randomized trial will compare 6-months of low-dose (65mg elemental iron daily) among prospective blood donors who are deferred for low haemoglobin but have passed all of the other pre-screening requirements for blood donation to a group of donors who were deferred from donating and receive the current standard of care (nutrition counseling only). An automated full blood count (FBC) will also be done to identify any safety concerns. The randomized trial will evaluate effectiveness with the primary outcome of at least one successful donation during a 12-month follow-up period. Safety will be evaluated by tracking iron supplementation related adverse events (e.g., lower gastrointestinal) and acceptability (e.g., compliance to study prescribed regimen) with monthly phone calls. Participants will be followed for a total of 12 months from screening with follow up phone calls at 4 weekly intervals. All participants will receive nutrition counselling and haemoglobin will be evaluated at screening. Individuals with very low haemoglobin (<10g/dl in females and <11g/dl in males) will be identified by an automated FBC at screening and referred for proper medical care. Sample size will be 264 per group: this gives 80% power for detecting an odds ratio of 2.6. With 2 donors recruited at each donation event, this will require 264 donation events. This corresponds to 2.5 donation events per week for 2 years or 2 donation events per week for 2.5 years.
Studies in the literature suggest that people with obesity have an excess of stored iron. There is possibly an inverse relationship between ferritin levels and the actions of insulin on glycemic control. The reduction of stored iron by simply donating blood could result in improvements in glycemic control in people with obesity and prediabetes. We propose, to reduce ferritin levels through a standard donation of a unit of whole blood, and to measure if it positively affects glycemic control.
2 different oral iron supplementations after blood donation are compared.
we compared the effect of 3 different kinds of liquids (water, Oral Rehydration Salt 3 and white granulated sugar water) intake in Vasovagal Reaction After Whole Blood Donation
Studies have suggested a positive relationship between prosociality and well-being. attempt to analyze the relationship between blood donation and subjective well-being, and try to figure out the moderators and mediators. Also, the investigators would like to compare difference of subjective well-being between donors who are explicitly presented with information that the participants' blood has saved patient's life and those who are not.
Rh negative blood group is a rare blood group in China, as it only accounts for 0.3-0.4 percent of the Han population. Therefore, low inventory is often found in blood collection and supply agencies in many regions in China. On July 22, 2020 blood stockpile of O-negative and A-negative in Guangzhou Blood Center reached the warning line, and we took measures for emergency recruitment. O-negative and A-negative blood donors whose last donation dates were between January 1, 2018 and December 31, 2019 were identified and randomly assigned to four groups. Three different recruitment text messages were send three groups. We observed the re-donation rates among four groups within one week.
The fight against the spread of the 2019-nCoV epidemic has achieved some success in China, but the epidemic is far from over. A key factor making the epidemic under control in China is the government's call for social distance, which has led to few people going out for donation. As a result, the number of blood donors on the streets has been continuing to decline. The first urgent recruitment of blood donors had been implemented during the period from 30 April to 10 May via emergency recruitment SMS . This second repeat trial has been designed to further confirm the results from the the first recruitment by comparing which information extraction frameworks would be more sensitive to blood donors in emergency situations.

As a result, the number of blood donors on the streets has been continuing to decline. Urgent recruitment of blood donors is therefore planned during the period from 30 April to 10 May via emergency recruitment SMS . This study has been designed to compare which information extraction frameworks would be more sensitive to blood donors in emergency situations.
