The Correlation of Thumbprint Patterns with Blood Group and Gender Among Students at Saint James School of Medicine

/in /by

This study explores the relationship between thumbprint patterns, blood groups, and gender among students at Saint James School of Medicine. The primary aim is to examine whether specific thumbprint characteristics are associated with blood group types and whether these patterns differ between male and female students. A total of 60 participants (31 males and 29 females) were involved in this study. Thumbprint patterns were classified into loops, double loops, whorls, tentarchs, and arches using a standardized classification system. Blood groups were identified through serological testing. Statistical analyses, including chi-square tests, were used to examine potential associations between thumbprint patterns, blood groups, and gender. Preliminary results suggest notable variations in thumbprint patterns across different blood groups, with some patterns being more common in specific groups. Additionally, gender differences were identified, indicating that male and female students display distinct thumbprint characteristics. These findings contribute to the understanding of biometric traits and their potential connections to genetic factors, such as blood group and gender. Further research is recommended to investigate the genetic and environmental factors influencing thumbprint patterns.

Correlation between Coagulation Profile and Blood group among patients with Ischemic Heart Disease in Khartoum State

Background: Coronary artery disease (CAD), also known as ischemic heart disease (IHD) is a group of diseases that includes stable angina, unstable angina, myocardial infarction, and sudden cardiac death. It’s considered a major public health issue that affects an estimated 1 in 3 adults in the United States. The ABO blood group and coagulation profile exerts a profound influence on hemostasis,

This study was aimed to correlate between ABO grouping & coagulation profile in Ischemic heart disease at Khartoum State.

Methods: This was case and control study conducted during the period from January to May 2021 at Ahmed gasim hospital. Study included hundred (100) sample, fifty (50) Ischemic heart disease (IHD) patients taken as cases and fifty (50) apparently healthy taken as controls. Blood samples were collected for the analysis of prothrombin time (PT), activated partial thromboplastin time (aPTT) using STart stago semi-automated instruments and for the determining the ABO blood group using direct slide agglutination method. Statistical analysis was performed using SPSS version 25.

Results: The results of study showed that the most frequent ABO blood type among all the participants among ischemic and healthy individuals was O. The mean level of APTT in Ischemic Heart Disease (IHD) showed that there was significantly decreased (27.06 ± 3.04) when compared to control group (29.45 ± 3.7) with p. value 0.001. However no significance differences in the mean level of PT between two groups (p value= 0.96).

Its also observed that among all study participants, in blood group A, the PT and aPTT levels were the least, while blood group O had the greatest PT and aPTT values. No association was found between ABO grouping and coagulation profile in ischemic heart disease in case and control group.

Conclusion: This study concluded that O blood group was more frequent among patients with IHD followed by A blood group and least frequent was AB. In addition, there was significant shorter aPTT in Ischemic Heart Disease cases when compared to control group.

No association was found between ABO grouping and coagulation profile in ischemic heart disease in case and control group.
