We conducted an epigenome-wide association study (EWAS) and investigated CUD-associated differentially methylated regions (DMRs). To explore the functional impact of CUD-related differential methylation, we performed Gene Ontology (GO) analyses and constructed co-methylation networks using weighted correlation network analysis. A more thorough investigation into epigenetic age in CUD was conducted using epigenetic clocks to assess biological age.
In the context of the BA9 analysis, although no cytosine-phosphate-guanine (CpG) site was found to be significantly associated with CUD at an epigenome-wide level, 20 differentially methylated regions (DMRs) were identified in association with CUD. Following the annotation of DMRs to genes, we discovered

The persistent issue of primary postpartum hemorrhage as a leading cause of maternal mortality globally, especially in resource-constrained nations like Ethiopia, highlights the critical need for improved healthcare infrastructure and an adequate supply of skilled medical professionals. The study lacks substantial or any information on the prevalence of primary postpartum hemorrhage within the evaluated patient group.
The 2021 objective of this study in Gedeo Zone, Southern Ethiopia, was to quantify the incidence of primary postpartum hemorrhage and analyze the factors linked to it among women who experienced childbirth.
In the Gedeo Zone, a facility-based cross-sectional study was conducted in public health facilities from January 1st, 2021, to March 30th, 2021. A random sample of 577 individuals was part of the research. A structured questionnaire, pre-tested and administered via interview, was employed to collect the data. Utilizing SPSS 23, the information collected was processed after being imported into Epi Info 35.1. Tables and graphs were used to effectively present the descriptive data. A logistic regression model was applied to the dataset and fitted to the results. To pinpoint the presence and intensity of association, a bivariate and multivariate logistic regression model was constructed.

The magnitude of primary postpartum hemorrhage, as determined, was 42% (with a 95% confidence interval ranging from 24% to 60%). A considerable link exists between postpartum hemorrhage and the presence of antepartum hemorrhage, evidenced by an adjusted odds ratio of 1167 (95% confidence interval 717-1617).
Within the Gedeo Zone, situated in the south of Ethiopia, 42% of cases involved primary postpartum hemorrhages. A combination of twin delivery, uterine atony, prolonged labor, and antepartum hemorrhage was found to be a key indicator for primary postpartum hemorrhage. Clinicians must promptly identify and address any issues arising in the early postpartum period to manage and prevent excessive blood loss, thereby potentially reducing the incidence of primary postpartum hemorrhage, considering the aforementioned points.
Within the population of the Gedeo Zone, Southern Ethiopia, 42% experienced primary postpartum hemorrhages. Primary postpartum hemorrhage was predicted by the presence of twin delivery, uterine atony, antepartum hemorrhage, and prolonged labor. The results demonstrate the necessity of prompt attention to early postpartum care, allowing clinicians to quickly pinpoint and address issues, prevent and treat excessive blood loss early, and potentially reduce primary postpartum hemorrhage rates, while considering previous factors.
A crucial factor in dry eye disease diagnosis is the tear meniscus height (TMH), which is an important indicator. Nonetheless, customary TMH measurement methods, being manual or semi-automatic in nature, render the TMH measurement process susceptible to subjective influences, protracted in duration, and demanding in effort. These problems were addressed by proposing a deep learning and image processing-based segmentation algorithm for the automatic determination of TMH. Employing the DeepLabv3 framework, the segmentation algorithm developed here for the tear meniscus region incorporates portions of the ResNet50, GoogleNet, and FCN architectures, thereby improving accuracy. The 305 ocular surface images examined in this study were categorized for both training and testing applications. Data from the training set was utilized to train the network model, while the testing set provided a platform to evaluate the performance of the trained model. In the experiment focused on tear meniscus segmentation, the key metrics showed an intersection over union of 0.896, a Dice coefficient of 0.884, and a sensitivity of 0.877. For the central ring of corneal projection ring segmentation, the intersection-over-union average was 0.932, the Dice coefficient was 0.926, and the sensitivity reached 0.947. The segmentation model's performance, as evaluated by the comparison of indices, surpassed that of existing models in this study. The proposed method's TMH measurement outcomes on the test data were ultimately contrasted with the findings from manual measurements. In a direct comparison of all measurement results, linear regression yielded a regression line of y = 0.98x – 0.02, along with an overall correlation coefficient of r² = 0.94. The presented method for measuring TMH in this paper closely mirrors manual measurements, enabling automated quantification and supporting clinician diagnosis of dry eye disease.
