In this study, we conducted newborn screening (NBS) using samples collected from umbilical cord blood in two hospitals on Santiago Island, Cape Verde. In newborns, HbS was detected using high-performance liquid chromatography (HPLC) on dried blood spot, with confirmation through polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP). In addition, we assessed the hematological and clinical characteristics of a second population group consisting of patients diagnosed with SCA. Haplotype determination was performed on both newborns with HbS and patients with SCA. Beta S-globin haplotypes were determined using PCR-RFLP. Hematological values were analyzed using standard methods. Out of 346 newborns, 21 (6%) were carriers of the sickle cell trait (HbAS) while none were identified as homozygous for sickle cell disease (HbSS). Among both groups of individuals, four haplotypes were identified: Senegal, Arabi-Indian, Bantu, and Benin. The Senegal haplotype was the most prevalent, possibly reflecting the ethnic origin of the mutations observed. Hematological values did not differ significantly among haplotypes. However, higher levels of HbF were associated with better hematological values. These findings suggest a positive impact of elevated HbF levels on reducing the severity of SCA.

Anemia has a negative impact on school children, including poor physical growth and reduced mental performance. Children show poor attentiveness, behavior, and memory and reduced school performance. There is limited evidence of the magnitude of anemia and associated factors in school-age children in Ethiopia, including the study area. Objective. To assess the magnitude of anemia and associated factors among public elementary school children in Asella Town, Southeast Ethiopia, in 2022. Methods. A school-based cross-sectional study was conducted in Asella Town from April 5 to May 5, 2022. A total of 442 school children aged 7–14 years were included in the study using the multistage sampling method. Data were collected using a pretested and semistructured questionnaire through a face-to-face interview technique. The hemoglobin concentration was determined by using the HemoCue 301+ analyzer. Anthropometric data and stool examinations were collected from participants. Data were entered into EpiData version 4.6, transported, and analyzed by Statistical Package for Social Sciences version 26. Bivariable and multivariable logistic regression analyses were carried out. Adjusted odds ratios along with their 95% confidence interval were used, and a p value of ≤0.05 was used for declaring statistical significance. Results. A total of 435 students with a mean age and standard deviation of 10.77 ± 2.21 years participated in the study. The magnitude of anemia was 78 (17.9%), with a 95% CI (14.3, 21.47). Of the participants, 63 (14.5%) were mild anemic and 15 (3.4%) were moderately anemic. Children whose mothers have no formal education (AOR = 3.94, 95% CI: 1.89, 8.21), underweight children (AOR = 3.83, 95% CI: 1.98, 7.40), and parasites in their stool (AOR = 3.72, 95% CI: 1.50, 9.20) were significantly associated with anemia in school-age children. Conclusion. Anemia among school-age children was found to be a mild public health problem. Uneducated mothers, intestinal parasite infections, and underweight children were found to be determinants of anemia among school-age children.

Anemia, a global health concern, affects one-fourth of the global population, particularly women. In Indonesia, its prevalence is 23.7%, with 32.0% among 15-24 year-olds. Factors include poor nutrition, infectious diseases, chronic diseases, inherited disorders, and inadequate healthcare access. This study aimed to investigate anemia prevalence and its etiology among medical students from Jakarta. Methods. This study was a descriptive research with a cross-sectional approach. Undergraduate students aged 18–23 years old were selected and consented to participate by a consecutive nonrandom sampling methods. Laboratory blood data were evaluated (including Hb, MCV, MCH, HbA2, and ferritin levels) and DNA was isolated to confirm the type of thalassemia carrier. Results. In total, 140 medical students, mainly female, were recruited. Anemia was found in 13.6% (11.4% had low MCV and/or MCH), and 16.5% had low MCV and/or MCH without anemia. Hb electrophoresis revealed high HbA2 values, suggesting the HbE variant (2.1%), and β-thalassemia carrier (0.7%). DNA analysis confirmed the cd26 mutation and heterozygous IVS1nt5. Among those without anemia, 5% had α-deletion, while in the group with anemia, 1.4% had α-deletion (with coexistent IDA), 3.6% had α-deletion, and 0.7% had β-mutation. Conclusion. DNA analysis can identify specific mutations associated with alpha-thalassemia, distinguishing between iron deficiency anemia and the alpha-thalassemia trait. Thalassemia screening should involve low MCV and/or MCH values as the first step (stage 1), followed by Hb analysis (stage 2) and DNA analysis (stage 3). In common areas, a combination of Hb and DNA testing is best. However, healthcare professionals must diagnose and treat thalassemia, as proper management relies on accurately identifying the underlying condition.","PeriodicalId":46055,"journal":{"name":"Anemia","volume":null,"pages":null},"PeriodicalIF":2.9,"publicationDate":"2024-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140710412","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, we aimed to assess the effects of TSH on SCD erythrocytes. The experiments were conducted using different concentrations of TSH (1, 2, 3, and 5 mIU/L). In HbS polymerization assay, erythrocytes were exposed to TSH in hypoxia to induce polymerization, and measurements were taken for 30 minutes. The deformability assay was made using Sephacryl-S 500 columns to separate deformable from nondeformable cells. Static adhesion test utilized thrombospondin to assess erythrocyte adhesion in the presence of TSH. TSH at all contractions were able to reduce polymerization of HbS and increase deformability. The static adhesion of erythrocytes at the lowest concentrations of 1 and 2 mIU/L were increased, but at higher contractions of 3 and 5 mIU/L, static adhesion was not modulated.

Objectives We determined the prevalence and risk factors for newborn anemia and its correlation with maternal anemia in southwestern Uganda. Methods This was a cross sectional study of 352 pregnant women presenting to the Mbarara Regional Referral Hospital for delivery. We collected maternal blood in labor and umbilical cord blood from the placental vein. We measured hemoglobin using a point-of-care Hemocue machine. We used summary statistics to characterize the study participants and compared demographic characteristics and outcomes using chi-square, t-test, and Wilcoxon rank sum analyses. We defined newborn anemia as umbilical cord hemoglobin <13 g/dl and measured the relationship between maternal and umbilical cord hemoglobin using linear regression analysis. Results The prevalence of newborn anemia was 17%. Maternal parity was significantly higher for anemic than nonanemic newborns (3 versus 2, P=0.01). The mean age in years (SD) was significantly lower for participants with umbilical cord hemoglobin <13 g/dl than those ≥13 g/dl (26 years [5.6] versus 28 [6.3], P=0.01). In multivariable linear regression analysis, a 1-point decrease in maternal hemoglobin was associated with a 0.14-point decrease in umbilical cord hemoglobin (P=0.02). Each one-unit increase in parity was associated with a 0.25-point decrease in umbilical cord hemoglobin (P=0.01). Cesarean delivery was associated with a 0.46-point lower umbilical cord hemoglobin level compared with vaginal delivery (P=0.03).
