Micronutrient levels and haemato-biochemical status of patients with sickle cell anaemia at a tertiary hospital in Abakaliki, south-eastern Nigeria: a cross-sectional study.

Introduction: nutritional status is an under-studied environmental factor that can impact the phenotypic manifestations of patients with Sickle Cell Anaemia (SCA). This study aimed to define hemato-biochemical parameters and micronutrient status in patients with SCA. Methods: this was a cross-sectional study of patients with SCA and hemoglobin genotype HBAA controls at a tertiary health facility in Abakaliki, from 2nd December 2020 to 31st March 2021. Plasma micronutrient levels, haemato-biochemical parameters were analyzed and anthropometric measurements obtained from all participants. Results: sixty participants with SCA had 58.3% females (mean age of 24.77±7.39 years) while controls had 50% females (mean age of 26.23 ± 8.44 years). The SCA group had significantly lowered calcium (2.733 ± 1.593 vs 1.846 ± 1.123 mmol/l; p=0.009) and magnesium (19.38 ± 6.37 vs 9.65 ± 1.38 mg/dl; p= < 0.001) levels but higher plasma iron (1.70 ± 0.89 vs 1.06 ± 0.53; p=0.001). Zinc and Copper did not reveal significant differences between the two groups. Chloride ion levels was significantly lower in the SCA patients (107.50 ± 17.42 vs 100.19 ± 12.92; p=0.026) while Alkaline phosphatase (ALP), bilirubin, total white blood cell (WBC) and platelets (PLT) count were higher compared with the HBAA group (255.72 ± 124.52 vs 134.56 ± 39.67; p= <0.001, 46.86 ± 25.03 vs 25.63 ± 18.80; p = 0.001, 13.21± 6.57 vs 6.10 ± 1.35; p= < 0.001 and 369.25 ± 138.11 vs 209.36 ± 47.85; p= <0.001). Conclusion: Copper and zinc deficiency was not present in our population of SCA patients but, they had lower plasma calcium and magnesium levels and elevated levels of blilirubin, ALP, WBC and platelets PLT counts. These parameters can be explored in designing better management for patients with SCA.

Prevalence of venous thromboembolism and its associations in a large racially homogenous population of sickle cell disease patients.

To determine the prevalence of venous thromboembolism (VTE) among adult sickle cell disease (SCD) patients in Nigeria. METHODS: This was a multicentre retrospective study in which the medical records of adult SCD patients were reviewed. Information on demographics, steady-state haemogram, clinical phenotypes, duration of follow-up, history of VTE including risk factors and management was collected. RESULTS: Of the 509 SCD patients with a median (IQR) duration of follow-up of 2 years, 10 (2.0%) had VTE (9 DVT and 1 PE). Their median (IQR) age was 27 (22.8-30.3) years. Identifiable risk factors for VTE included positive family history (2, 20%) surgery, splenectomy, paraplegia and cancer (1, 10% each). No risk factor was identifiable in four persons. VTE had no significant association with age and gender. VTE was significantly associated with the following events: acute chest syndrome [p = .002, odds ratio (OR) 8, 95% CI 2.2-28.9], osteonecrosis [p = .012, OR 5.24, 95% CI, 1.45-18.91] and vaso-occlusive crisis [p = .035]. Also significantly associated with VTE were pulmonary hypertension [p = .001, OR 23.3, 95%CI 5.18-105.06] and stroke [p = .032, OR 9.35, 95%CI 0.87-53.25]. CONCLUSION: The prevalence of VTE among SCD patients in Nigeria is low. It is significantly associated with vaso-occlusive crisis, pulmonary hypertension and stroke.

Donor Blood Procurement, Safety, and Clinical Utilization: A Study of Blood Transfusion Services in a Tertiary Care Hospital in Nigeria.

Background: Donated blood is an essential component of the management of many diseases, and hospital-based blood banks in Nigeria are saddled with the responsibility of provision of safe blood and coordination of its appropriate utilization for patient care. Objective: This study reviewed the extent to which the hospital blood transfusion service ensures adequate safe blood supply and utilization. Materials/Methods. This was a retrospective study of 2 years record of the blood bank service of Alex Ekwueme Federal University Teaching. Methods of donor blood procurement, transfusion transmissible infection status, the pattern of blood, and blood component usage across the hospital's clinical departments were evaluated. Statistical analysis was conducted using IBM SPSS, and data were presented as percentages. Fisher's tests were used to test significance, and p value <0.05 is significant. Results: The highest proportion of donors was male family replacement donors aged 26-35 years (3634 (39.68%)) while total voluntary donors were 315 (2.65%). Hepatitis B had the highest seroprevalence 267 (2.22%) among blood-borne diseases screened. National Blood Transfusion Service (NBTS) supplied only 3 (0.03%) of total blood units used. The accident and emergency department had the highest proportion of persons who utilized whole blood; 4568 (99.96%). Conclusion: The hospital blood bank relies heavily on family replacement donors with little or no assistance from the National Blood Transfusion Service. Family replacement donors have the highest risk of TTIs, and hepatitis B infection has the highest prevalence. The high cost of blood component therapy increases the need for whole blood.

Diagnostic Challenges of Anaplastic Large Cell Lymphoma in a Resource-Limited Setting: A Case Report and Literature Review.

Anaplastic large cell lymphoma (ALCL) is a rare variety of non-Hodgkin's lymphoma with diverse morphologic variants. Due to the similarity of the different variants with other lymphoma entities, misdiagnosis may be inevitable when immunohistochemical and cytogenetic techniques are not available and histology alone is employed. We report a case of a 43-year-old woman with a seven-month history of neck swelling which was complicated by ulceration of the mass and pathological fracture of the right clavicle after two months delay in arriving at a correct diagnosis. Several attempts to arrive at definitive diagnosis using histology alone gave divergent reports which all misdiagnosed the case until it was sent to a facility outside the country. Our report highlights the limitations and challenges of histology in making a definitive diagnosis of ALCL and the overt importance of immunohistochemical and cytogenetic techniques which are largely unavailable in resource-constrained environment typical of tertiary centers in Nigeria and most sub-Saharan Africa countries.

Effect of digital storytelling intervention on burnout thoughts of adolescent: Athletes with disabilities.

BACKGROUND/OBJECTIVE: Both athletes with and without disabilities can develop burnout symptoms. However, athletes with disabilities may face different or more challenges compared to their counterparts without disabilities. The present study aimed at ascertaining the effect of digital storytelling intervention on burnout thoughts of adolescent-athletes with disabilities. METHOD: This study is a randomized controlled trial involving a total of 171 adolescent-athletes with disabilities who showed a high degree of burnout symptoms. These adolescent-athletes were randomly assigned to either an intervention group (n = 85) or a waitlisted control group (n = 86). The treatment intervention for the adolescent-athletes was digital stories which were created based on the framework of rational emotive behaviour therapy (REBT). The Athlete Burnout Questionnaire was used for gathering of data at three different times (baseline, post-test and follow up). Data were analyzed using repeated measure analysis of variance at a significant level of 0.05. RESULTS: Results showed that the digital storytelling intervention based on REBT significantly reduced burnout thoughts among disabled adolescent-athletes in the intervention group compared to athletes in the waitlisted control group as measured by the Athlete Burnout Questionnaire. Additionally, at follow-up evaluation, it was observed that the decrease in burnout scores was maintained by those athletes in the digital storytelling intervention. CONCLUSION: Digital storytelling intervention based on rational emotive behaviour therapy shows great potentials in addressing burnout among adolescent-athletes with disabilities.
