Abstract Background: Millions of lives around the world are being saved annually through blood transfusion. However, blood transfusion is among the important vehicles for transmitting infections. The overall prevalence of Transfusion Transmissible Infections (TTIs) among blood donors differs around the world, reflecting the variation in the prevalence of these infections. The aim of this study is to assess the prevalence and trends of TTIs among blood donors in Qatar. Methods: This is a cross sectional study utilizing donation records of a five-year period from January 2013 to December 2017. Results for all screening and confirmatory tests for Hepatitis B Virus (HBV), Hepatitis C Virus (HCV), Human T-Lymphotropic Virus-I/II (HTLV-I/II), Syphilis and Malaria were included in the study. Results: Among the 190,509 donations received at the donation center during the study period, about 91% donations were received from males and 9% from females. The overall positivity rate for all tests were 1.95, 2.18, 1.62, 1.81 and 1.85 for the years 2013 through 2017. The overall positivity rates for HBV, Syphilis and Malaria were 0.30, 0.43 and 0.20, respectively. Throughout the years, the positivity rates decreased for HBV, Syphilis and Malaria and increased for HCV and HTLV. Conclusion: The overall positivity rate of all tests combined for the TTIs demonstrated a gradual increasing trend from 2013 to 2017. The rates for HCV and HTLV showed increasing trends too. To support developing effective prevention and control strategies, further investigations are needed to improve the estimations of the prevalence of these infections.

Background: Platelets are an important constituent of blood. Safety measures of blood transfusion are important for optimum health environment. To the knowledge of the researchers, there is no study that was conducted concerning Platelets count in apparently healthy Eritrean blood donors. Therefore, this study will help in establishing the reference ranges of Platelets count in them. Objectives: To measure the serum platelets levels and mean platelets volume in apparently healthy Eritrean blood donors attending the national blood bank of Eritrea. Study design: Descriptive crosssectional study. Materials and methods: 610 Blood donors were incorporated in the study. 4 ml of venous blood was collected into K3EDTA tubes (Becton Dickinson, Plymouth, UK) from all of the participants of the study. Blood samples collected into the (EDTA)-tubes were examined for Platelets count and mean platelet volume. Results: The overall mean of platelets count was 267.145 ± (65.915) ×109 /L, The median and mode of values were both 266.3 thousands/mm3. The mean platelet count for the females was 296.122 thousands /mm3, and for males was 252.477 ×109 /L, and the statistic difference between them was significant. The statistic mean of MPV for males was 8.763 fl, and for females was 8.717, and the difference between the two means also considered insignificant. Conclusion: This descriptive cross sectional study was performed in the National Blood bank in Asmara where platelets levels and mean platelets volume were measured for 610 healthy blood donors. The results were found to be within reference normal ranges. The difference between the males and females results was statistically significant

BACKGROUND Even in the presence of sufficient voluntary blood donors, the need of blood is not met yet. We wanted to evaluate the causes that hinder the smooth functioning of well-maintained blood transfusion services (BTS). METHODS This is a population based cross-sectional study conducted among blood donors from voluntary outreach blood donation camp for period of one year. Total 1536 blood donors from 32 blood donation camps were subjected to study for the sociodemographic characteristic and their knowledge of blood donation. Statistical analysis of data was done using Microsoft Excel, analysed using statistical package for social sciences (SPSS) ver.16 software. RESULTS A total of 32 blood donation camps were conducted during the study period that provided 1536 donors. In most of the camps, male donors (75 %) were more than female donors. Donors of age group of 30 to 39 years (43.9 %) were more when compared to others. Donors those who were married accounted for 79.9 %. Blood donors of Hindu religion (53 %) were more. CONCLUSIONS The main hindrance for blood donor motivation is lack of knowledge. Literacy and chance to mingle in society have a positive effect on blood donor motivation. Targeting of effective donor motivation, recruitment, and retention were attained by conducting awareness classes, seminars, workshops, and visual communication modalities.

Hepatitis B Virus (HBV) and Hepatitis C Virus (HCV) infections lead to chronic diseases and are the most common causes of liver cirrhosis and cancer in developing countries like Nepal. The study is carried out to determine the seroprevalence of HBV and HCV by using a Rapid kit method and Elisa Method to find out its risk factors. The cross-sectional study was done among blood donating people from 16th August 2016 to 19th November 2016. Blood donors in Pokhara Valley were screened for anti-HCV antibodies, anti-HBV antibodies using third generation ELISA kits and automated ELISA Processor in serology laboratory at Central Blood Transfusion Service (CBTS) of Nepal Red Cross Society (NRCS) in Pokhara, Nepal. 1777 (87.2%) units were male blood donors and 260 (12.6%) units were female donors out of 2037 participants. Gender wise, the ratio between male and female was 1:0.1. HBV and HCV infection rate in blood donors were detected at 0.7% (15/2037) and 0.5% (8/2037) respectively. HBV infection rate in volunteer blood donor people was 0.7% (14/1881) which was higher than the replacement donors i.e. 0.6% (1/156). Similarly, in HCV infection rate in volunteer donor were 0.4% (8/1881). HBV infected people are detected higher than the HCV infected people among the blood donors. In addition, there was no significant relationship between positive results of HBV and HCV tests with the gender, age, tattoo, donor type.

Background: Hepatitis A virus (HAV) infection is endemic in Iran. Detection of the seroprevalence of HAV is necessary to evaluate the feasibility of infection control strategies in the population. Objectives: This study aimed to determine the seroprevalence of HAV among blood donors as a representative sample of the general population. Methods: In this cross-sectional study, 268 blood samples were randomly selected from donors, presenting to the Iranian Blood Transfusion Organization in Sanandaj, Iran, in 2019. The collected sera were measured for anti-HAV antibodies (IgG and IgM), using ELISA assays. Also, demographic data, including age, gender, marital status, education, occupation, and blood donation status, were collected. The test results and demographic data were analyzed in STATA software. Results: The mean age of the blood donors was 37.79 ± 10.64 years, and 88.43% of them were male. Out of 268 blood samples, 218 (81.34%) were positive for anti-HAV antibodies. The antibody positivity was significantly correlated with age (P = 0.014) and marital status (P = 0.027). The majority of anti-HAV positive cases were found among farmers and ranchers (93.33%) (P = 0.045). Conclusions: A large proportion of blood donors had anti-HAV antibodies and were immune to HAV infection. Therefore, HAV was endemic in the study area.

BackgroundNon-communicable lung disease and exposure to air pollution are major problems in sub-Saharan Africa. A high burden of chronic respiratory symptoms, spirometric abnormalities and air pollution exposures has been found in Malawian adults; whether the same would be true in children is unknown.MethodsThis cross-sectional study of children aged 6–8 years, in rural Malawi, included households from communities participating in the Cooking and Pneumonia Study (CAPS), a trial of cleaner-burning biomass-fuelled cookstoves. We assessed; chronic respiratory symptoms, anthropometry, spirometric abnormalities (using Global Lung Initiative equations) and personal carbon monoxide (CO) exposure. Prevalence estimates were calculated, and multivariable analyses were done.ResultsWe recruited 804 children (mean age 7.1 years, 51.9% female), including 476 (260 intervention; 216 control) from CAPS households. Chronic respiratory symptoms (mainly cough (8.0%) and wheeze (7.1%)) were reported by 16.6% of children. Average height-for-age and weight-for-age z-scores were −1.04 and −1.10, respectively. Spirometric abnormalities (7.1% low forced vital capacity (FVC); 6.3% obstruction) were seen in 13.0% of children. Maximum CO exposure and carboxyhaemoglobin levels (COHb) exceeded WHO guidelines in 50.1% and 68.5% of children, respectively. Children from CAPS intervention households had lower COHb (median 3.50% vs 4.85%, p=0.006) and higher FVC z-scores (−0.22 vs −0.44, p=0.05) than controls.ConclusionThe substantial burden of chronic respiratory symptoms, abnormal spirometry and air pollution exposures in children in rural Malawi is concerning; effective prevention and control strategies are needed. Our finding of potential benefit in CAPS intervention households calls for further research into clean-air interventions to maximise healthy lung development in children.

Abstract Background: Yemen is facing major challenges in ensuring the safety and availability of blood transfusion to meet the increased demand for blood transfusion due to the protracted conflict. However, Transfusion-transmissible infectious (TTIs) agents such as hepatitis B virus (HBV), hepatitis C virus (HCV), human immunodeficiency virus (HIV), syphilis and malaria remain the greatest threats for blood transfusion safety in such fragile, conflict-affected and vulnerable settings. This study aimed to determine the magnitude of TTIs among blood donors attending National Blood Transfusion and Research Center (NBTRC) and its associated factors. Methods: Cross- sectional study was conducted on 340 blood donors at the NBTRC during November and December 2017. Data was collected through face-to-face interview using a predesigned questionnaire that covered socio-demographic characteristics and possible TTIs associated factors. Blood samples were drawn and tested for HBV surface antigen (HBsAg), HCV antibodies, HIV1, 2 by using electrochemi-luminescence immunoassay technique and rapid immunochromato-graphic for screened syphilis and malaria antibodies. Result: The overall prevalence of TTIs was 8.8% where 2.5 %, 1.2%, 0.3%, 1.2%, 3.2% have HBV, HCV, HIV, syphilis and malaria respectively. HBV was significantly associated with history of jaundice and cupping. Furthermore, urethero-vaginal excretion was significantly associated with syphilis while malaria was significantly higher among donors from malaria endemic areas. Nearly three-fourth of donations were from replacement donors who had significantly higher TTIs prevalence than the voluntary donors: 10.4% vs. 3.3%, OR 3.4 (CI: 1.1-11.6). Conclusions: Although the prevalence of TTIs is low, it poses a serious risk for blood recipients especially in in fragile, conflict-affected and vulnerable settings where needs for blood transfusion are increasing and resources are limited. Therefore, using more sensitive screening methods and establishment of TTIs surveillance system should be considered. Efforts should be made to improve donor recruitment procedures and increase the proportion of regular and voluntary donation.

A cross - sectional study was conducted from November 2009 to March 2010 on cysticercosis ( Cystice rcus bovis ) and cystic echinococcosis in cattle slaughtered at Mekelle municipality abattoir in Tigray region of Ethiopia with over all objectives of determining the prevalence of metacestods and providing the baseline data on their status and socio econom ic importance in the study area. Accordingly, a total of 1800 randomly selected slaughtered cattle were examined both during ante mortem and postmortem inspection and then a prevalence of 22.2% (399/1800) for hydatidosis and 4.44% (80/1800) for cysticercos is observed. The distribution of Cysticercosis in infected organs and tissue showed: masseter muscle and heart (0.2%), lung (0.7%), tongue (0.4%) and liver (3.1%). The logistic regression analysis of potential risk factors revealed that there was statistic ally insignificant difference in the prevalence of taeniasis between animals from different origin and age (P > 0.05). Regarding the distribution of hydatid cyst; lung (13%), liver (8.2%), spleen (0.44%), kidney (0.17%) and heart (0.3%). Study results indi cated that age, body condition and origin have significant effect (P < 0.05) on the prevalence of the disease. A lower percentage of calcified cysts (23.3%) out of cyst examined and relatively high percentage, 37.8% and 38.9% of the total cysts were fertil e and sterile, respectively. The total annual economic loss from organ condemnation and carcass weight loss due to hydatidosis and cysticercosis was estimated to be 930,918.52 ETB. The result of this study revealed that metacestode is the major disease cau sing direct and indirect economic losses significantly in the study area. Control strategies should be instituted taking into account the social, cultural and economic condition at the study area.
