What the literature leaves open

  • There is a need to identify parameters associated with adverse outcomes in sickle cell disease. There is a need to evaluate the clinical profile of adult patients with sickle cell disease.

    Impact of hydroxyurea use on severity and hematologic profile in children with sickle cell disease at University of Benin Teaching Hospital, Benin city, Nigeria · 2026 · DOI

  • Physical challenges in managing children's needs. Emotional challenges in coping with the demands of caregiving. Social challenges in balancing caregiving responsibilities with other family and work obligations.

    Fenomena Perawatan Anak Thalasemia di Rumah dari Perspektif Ibu · 2026 · DOI

  • There is a lack of understanding of mothers' experiences in caring for children with thalassemia at home. Previous studies have focused on the medical aspects of thalassemia, with limited attention to the social and emotional impacts on families.

    Fenomena Perawatan Anak Thalasemia di Rumah dari Perspektif Ibu · 2026 · DOI

  • The study faces challenges in terms of data collection and analysis in resource-limited settings. The study has to deal with the lack of evidence on the real-world implementation and effectiveness of Hydroxyurea in resource-limited primary care settings. The study has to consider the potential biases and limitations of a retrospective cohort design.

    Hydroxyurea treatment for sickle cell disease in Nairobi informal settlements: a retrospective cohort study · 2026 · DOI

  • The sample size was limited to 100 patients. The study was conducted in a single tertiary hospital, limiting generalizability. The study did not investigate delayed puberty and hormonal factors.

    A study of anthropometric parameters in children with beta thalassemia major · 2026 · DOI

  • Limited treatment options due to hypersensitivity to deferasirox. Difficulty in controlling iron burden.
