Platelet transfusion practices among neonatologists in Saudi Arabia: A nationwide cross-sectional survey.

The etiologies of thrombocytopenia are highly diverse; however, early neonatal thrombocytopenia might be more common among extremely low-weight neonates. Therefore, in this study, we aimed to examine the current neonatal platelet (PLT) transfusion practices in Saudi Arabia. This is a cross-sectional online survey study that was conducted between October and December 2022. Convenience sampling was used to recruit the participants. In this study, we developed a questionnaire based on an extensive literature review to examine current neonatal PLT transfusion practices. A total of 81 neonatologists participated. The vast majority of them (85.2%) were practicing in a level 3 neonatal intensive care unit, with 60.0% of them reporting that they transfuse PLTs over 1 hour. Around 53% reported that they typically order 10 mL/kg per PLT transfusion. Up to 34.6% of the study participants reported that they use pooled whole-blood-derived PLT products in their practicing unit. Almost half (48.0%) of the study participants reported that they have written guidelines for PLT transfusion in their practicing unit, with 81.1% reporting that the PLT transfusion threshold was stated in the guidelines. Neonatal thrombocytopenia is typically treated with PLT transfusions. PLT transfusion criteria should be lowered in light of recent evidence suggesting that doing so may be counterproductive. However, there is some disagreement about whether a PLT count constitutes a medical emergency requiring a transfusion for a newborn baby. Furthermore, there is a great deal of variation in the administration of PLT infusions in Saudi Arabia because of the absence of clear protocols. Strict neonatal PLT transfusion standards and carefully planned clinical research are needed to address the risks and/or benefits of these diverse methods.

Evaluate the side effect associated with COVID-19 vaccine on adolescents in Riyadh, Saudi Arabia: A cross-section study.

OBJECTIVES: To investigate the side effects of Pizer- BioNTech mRNA (BNT162b2) and Spikevax (mRNA- 1273) Coronavirus disease 2019 (COVID-19) vaccines on adolescents in Riyadh, Saudi Arabia. METHODS: A cross-sectional study using an online questionnaire was carried out among COVID-19 vaccine adolescent recipients in Riyadh, Saudi Arabia. After receiving at least one dose of each vaccine, general and demographic data were collected, and vaccine-related side effects were evaluated. RESULTS: The final sample consisted of 604 participants with a majority age group of 16-17 years old. Approximately 89.1% of the study participants were female. Most participants reported pain at the injection site (85.1% 1st dose, 79.8% 2nd dose), feeling tired, and headache (58.6% 1st dose, 64.2% 2nd dose). Moreover, we found that patients who took the first dose and had a chronic disease had 2.4 times higher odds of having menstrual disorder (females) than non-chronic disease patients (p=0.03) and 4.5 times higher odds of exhibiting breathing congestion (p=0.01). In addition, patients with chronic disease had 2.4 times higher odds of exhibiting muscle and joint pain and dizziness than non-chronic disease patients (p=0.01, p=0.02). Males were less likely to have dizziness after the first dose than females (OR=0.26, p=0.01). CONCLUSION: This study investigates the adverse effects of COVID-19 vaccines among adolescents in Riyadh. As a result, this study creates a database to inform people about the risk of experiencing side effects based on their gender, age, and the vaccine type; more investigation is needed to better understand the link between risk factors and the development of adverse effects.
