Abstract
BACKGROUND Children with thalassemia are generally dependent on blood transfusions and face a lot of stress and alteration in their physiological parameters through the procedure. AIM: This study aimed to investigate the effect of Benson's relaxation technique versus music intervention on physiological parameters and stress of children with thalassemia during blood transfusions. DESIGN A randomized, controlled trial with three parallel groups. METHODS One hundred and twenty preschool-age children with thalassemia who underwent blood transfusions were randomly assigned to three groups. Children of the control group received only routine hospital care through blood transfusions. Music intervention group children listened to recorded Mozart's music and children of Benson's relaxation group received relaxation intervention before and during the blood transfusions. Outcome measures were physiological parameters and behavioral distress levels. SETTING Hematology outpatient clinic of the Children's University Hospital at El-Shatby in Alexandria from October 2022 to February 2023. RESULTS The mean total score of children's behavioral responses to stress before the blood transfusions procedure was 19.32 ± 4.08, 14.20 ± 0.93, and 16.92 ± 4.74 in the control, music, and Benson groups, respectively. Beyond that, there was a decline in their physiological parameters and behavioral stress response during and after procedure among groups of study (P = 0.005 & <0.001, respectively). CONCLUSION Music and Benson's relaxation interventions had a helpful effect on stabilizing the physiological parameters and reducing behavioral distress levels in children with thalassemia undergoing blood transfusions. PRACTICE IMPLICATIONS This study directs paediatric nurses to apply Benson's relaxation and music interventions for children with thalassemia to enhance their responses.

Abstract
BACKGROUND Knowledge about the risk for bleeding in patients with hemophilia (PWH) would be relevant for patients, stakeholders, and policy makers. OBJECTIVES to perform a systematic review of the literature on risk assessment models (RAMs) and risk factors for bleeding in PWH on regular prophylaxis. METHODS We searched MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials, and the Cochrane Database of Systematic Reviews from inception through August 2019. In duplicate, reviewers screened the articles for inclusion, extracted data, and assessed the risk for bias using the QUIPS tool. A qualitative synthesis of the results was not performed due to high heterogeneity in risk factors, outcomes definition and measurement, and statistical analysis of the results. RESULTS From 1843 search results, 10 studies met the inclusion criteria. No RAM for the risk for bleeding in PWH was found. Most studies included only PWH A or both PWH A and B and were conducted in North America or Europe. Only one study had a low risk for bias in all the domains. Eight categories of risk factors were identified. The risk for bleeding was increased when factor levels were lower and in people with a significant history of bleeding or who engaged in physical activities involving contact. CONCLUSIONS Our findings suggest that plasma factor levels, history of bleeds, and physical activity should be considered for the derivation analysis when building a RAM for bleeding in PWH, and the role of other risk factors, including antithrombotic treatment and obesity, should be explored.

Abstract
BACKGROUND Despite ~90% of sickle cell disease (SCD) occurring in low-and middle-income countries (LMICs), the vast majority of people are not receiving evidence-based interventions (EBIs) to reduce SCD-related adverse outcomes and mortality, and data on implementation research outcomes (IROs) and SCD is limited. This study aims to synthesize available data on EBIs for SCD and assess IROs. METHODS We conducted a systematic review of RCTs reporting on EBIs for SCD management implemented in LMICs. We identified articles from PubMed/Medline, Global Health, PubMed Central, Embase, Web of Science medical subject heading (MeSH and Emtree) and keywords, published from inception through February 23, 2020, and conducted an updated search through December 24, 2020. We provide intervention characteristics for each study, EBI impact on SCD, and evidence of reporting on IROs. MAIN RESULTS 29 RCTs were analyzed. EBIs identified included disease modifying agents, supportive care agents/analgesics, anti-malarials, systemic treatments, patient/ provider education, and nutritional supplements. Studies using disease modifying agents, nutritional supplements, and anti-malarials reported improvements in pain crisis, hospitalization, children's growth and reduction in severity and prevalence of malaria. Two studies reported on the sustainability of supplementary arginine, citrulline, and daily chloroquine and hydroxyurea for SCD patients. Only 13 studies (44.8%) provided descriptions that captured at least three of the eight IROs. There was limited reporting of acceptability, feasibility, fidelity, cost and sustainability. CONCLUSION EBIs are effective for SCD management in LMICs; however, measurement of IROs is scarce. Future research should focus on penetration of EBIs to inform evidence-based practice and sustainability in the context of LMICs. CLINICAL TRIAL REGISTRATION This review is registered in PROSPERO #CRD42020167289.

Abstract
OBJECTIVE Adherence to medication regimens is of critical importance in sickle cell disease (SCD). Most notably, data indicate that hydroxyurea, penicillin, and iron chelators increase life expectancy and decrease comorbid medical problems (e.g., strokes). However, average pediatric SCD adherence rates are only 55-74%. Studies have introduced interventions for pediatric SCD adherence, but no review has synthesized these data. METHODS We conducted a systematic review of interventions for enhancing medication adherence in pediatric SCD. There were 9 studies that met inclusion and exclusion criteria. The Pediatric Self-Management Model provided a framework for organizing the modifiable factors targeted by existing interventions. RESULTS The 9 studies had high risk of bias levels and most targeted hydroxyurea. All studies used multiple measures of adherence, the interventions were multicomponent, and most included behavioral or technological interventions. There was variability in terms of whether the intervention targeted the individual, family, community, or healthcare system. CONCLUSIONS Consistent with the broader adherence literature, targeting knowledge alone was insufficient in increasing adherence. Findings suggest that reminders and targeting self-efficacy were key to success. In addition, addressing multiple domains in an intervention yielded larger effects on adherence. Although these results are promising, this review highlights several limitations of the extant literature, including a paucity of intervention studies and several methodological weaknesses, such as small sample sizes, few randomized controlled trials, and variable measures of adherence. Recommendations for advancing scientific understanding of adherence promoting interventions in pediatric SCD are provided.
PICO Summary
Population
Paediatric patients with sickle cell disease (SCD), (9 studies, n=247).

Abstract
BACKGROUND Sickle cell disease is one of the commonest severe monogenic disorders in the world, due to the inheritance of two abnormal haemoglobin (beta globin) genes. Sickle cell disease can cause severe pain, significant end-organ damage, pulmonary complications, and premature death. Stroke affects around 10% of children with sickle cell anaemia (HbSS). Chronic blood transfusions may reduce the risk of vaso-occlusion and stroke by diluting the proportion of sickled cells in the circulation. This is an update of a Cochrane Review first published in 2002, and last updated in 2017. OBJECTIVES To assess risks and benefits of chronic blood transfusion regimens in people with sickle cell disease for primary and secondary stroke prevention (excluding silent cerebral infarcts). SEARCH METHODS We searched for relevant trials in the Cochrane Library, MEDLINE (from 1946), Embase (from 1974), the Transfusion Evidence Library (from 1980), and ongoing trial databases; all searches current to 8 October 2019. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Haemoglobinopathies Trials Register: 19 September 2019. SELECTION CRITERIA Randomised controlled trials comparing red blood cell transfusions as prophylaxis for stroke in people with sickle cell disease to alternative or standard treatment. There were no restrictions by outcomes examined, language or publication status. DATA COLLECTION AND ANALYSIS Two authors independently assessed trial eligibility and the risk of bias and extracted data. MAIN RESULTS We included five trials (660 participants) published between 1998 and 2016. Four of these trials were terminated early. The vast majority of participants had the haemoglobin (Hb)SS form of sickle cell disease. Three trials compared regular red cell transfusions to standard care in primary prevention of stroke: two in children with no previous long-term transfusions; and one in children and adolescents on long-term transfusion. Two trials compared the drug hydroxyurea (hydroxycarbamide) and phlebotomy to long-term transfusions and iron chelation therapy: one in primary prevention (children); and one in secondary prevention (children and adolescents). The quality of the evidence was very low to moderate across different outcomes according to GRADE methodology. This was due to the trials being at a high risk of bias due to lack of blinding, indirectness and imprecise outcome estimates. Red cell transfusions versus standard care Children with no previous long-term transfusions Long-term transfusions probably reduce the incidence of clinical stroke in children with a higher risk of stroke (abnormal transcranial doppler velocities or previous history of silent cerebral infarct), risk ratio 0.12 (95% confidence interval 0.03 to 0.49) (two trials, 326 participants), moderate quality evidence. Long-term transfusions may: reduce the incidence of other sickle cell disease-related complications (acute chest syndrome, risk ratio 0.24 (95% confidence interval 0.12 to 0.48)) (two trials, 326 participants); increase quality of life (difference estimate -0.54, 95% confidence interval -0.92 to -0.17) (one trial, 166 participants); but make little or no difference to IQ scores (least square mean: 1.7, standard error 95% confidence interval -1.1 to 4.4) (one trial, 166 participants), low quality evidence. We are very uncertain whether long-term transfusions: reduce the risk of transient ischaemic attacks, Peto odds ratio 0.13 (95% confidence interval 0.01 to 2.11) (two trials, 323 participants); have any effect on all-cause mortality, no deaths reported (two trials, 326 participants); or increase the risk of alloimmunisation, risk ratio 3.16 (95% confidence interval 0.18 to 57.17) (one trial, 121 participants), very low quality evidence. Children and adolescents with previous long-term transfusions (one trial, 79 participants) We are very uncertain whether continuing long-term transfusions reduces the incidence of: stroke, risk ratio 0.22 (95% confidence interval 0.01 to 4.35); or all-cause mortality, Peto odds ratio 8.00 (95% confidence interval 0.16 to 404.12), very low quality evidence. Several review outcomes were only reported in one trial arm (sickle cell disease-related complications, alloimmunisation, transient ischaemic attacks). The trial did not report neurological impairment, or quality of life. Hydroxyurea and phlebotomy versus red cell transfusions and chelation Neither trial reported on neurological impairment, alloimmunisation, or quality of life. Primary prevention, children (one trial, 121 participants) Switching to hydroxyurea and phlebotomy may have little or no effect on liver iron concentrations, mean difference -1.80 mg Fe/g dry-weight liver (95% confidence interval -5.16 to 1.56), low quality evidence. We are very uncertain whether switching to hydroxyurea and phlebotomy has any effect on: risk of stroke (no strokes); all-cause mortality (no deaths); transient ischaemic attacks, risk ratio 1.02 (95% confidence interval 0.21 to 4.84); or other sickle cell disease-related complications (acute chest syndrome, risk ratio 2.03 (95% confidence interval 0.39 to 10.69)), very low quality evidence. Secondary prevention, children and adolescents (one trial, 133 participants) Switching to hydroxyurea and phlebotomy may: increase the risk of sickle cell disease-related serious adverse events, risk ratio 3.10 (95% confidence interval 1.42 to 6.75); but have little or no effect on median liver iron concentrations (hydroxyurea, 17.3 mg Fe/g dry-weight liver (interquartile range 10.0 to 30.6)); transfusion 17.3 mg Fe/g dry-weight liver (interquartile range 8.8 to 30.7), low quality evidence. We are very uncertain whether switching to hydroxyurea and phlebotomy: increases the risk of stroke, risk ratio 14.78 (95% confidence interval 0.86 to 253.66); or has any effect on all-cause mortality, Peto odds ratio 0.98 (95% confidence interval 0.06 to 15.92); or transient ischaemic attacks, risk ratio 0.66 (95% confidence interval 0.25 to 1.74), very low quality evidence. AUTHORS' CONCLUSIONS There is no evidence for managing adults, or children who do not have HbSS sickle cell disease. In children who are at higher risk of stroke and have not had previous long-term transfusions, there is moderate quality evidence that long-term red cell transfusions reduce the risk of stroke, and low quality evidence they also reduce the risk of other sickle cell disease-related complications. In primary and secondary prevention of stroke there is low quality evidence that switching to hydroxyurea with phlebotomy has little or no effect on the liver iron concentration. In secondary prevention of stroke there is low-quality evidence that switching to hydroxyurea with phlebotomy increases the risk of sickle cell disease-related events. All other evidence in this review is of very low quality.
PICO Summary
Population
Patients of all ages with sickle cell disease (SCD), (5 studies, n= 660).
Intervention
Red cell transfusions.
Comparison
Standard care, or hydroxyurea and phlebotomy.
Outcome
Red cell transfusions versus standard care: long term transfusions probably reduce the incidence of clinical stroke in children with a higher risk of stroke (abnormal transcranial doppler velocities or previous history of silent cerebral infarct). Long-term transfusions may: reduce the incidence of other sickle cell disease-related complications but make little or no difference to IQ scores. We are very uncertain whether long-term transfusions reduce the risk of transient ischaemic attacks, have any effect on all-cause mortality, or increase the risk of alloimmunisation. Hydroxyurea and phlebotomy versus red cell transfusions and chelation: Neither trial reported on neurological impairment, alloimmunisation, or quality of life. Switching to hydroxyurea and phlebotomy may have little or no effect on liver iron concentrations. We are very uncertain whether switching to hydroxyurea and phlebotomy has any effect on: risk of stroke, transient ischaemic attacks or other sickle cell disease-related complications. Switching to hydroxyurea and phlebotomy may: increase the risk of sickle cell disease-related serious adverse events, but have little or no effect on median liver iron. We are very uncertain whether switching to hydroxyurea and phlebotomy: increases the risk of stroke, or has any effect on all-cause mortality, or transient ischaemic attacks.

Abstract
PURPOSE beta-Thalassemia is an inherited blood disorder characterized by reduced or no production of adult hemoglobin. Systematic identification of the burden of beta-thalassemia with contemporary treatments is lacking in published literature. Thus, a gap exists in understanding the baseline burden on which to assess future treatments. Therefore, a systematic literature review (SLR) was performed to assess management and outcomes in patients with transfusion-dependent beta-thalassemia (TDT) who received long-term transfusion regimens. METHODS Searches of MEDLINE, EMBASE, and 5 conference websites were conducted to identify clinical-practice studies in Italy, France, Germany, Greece, the United States, and the United Kingdom, published since January 2007. The review found 135 articles meeting the SLR criteria. FINDINGS Among patients carrying 2 beta-thalassemia mutations, 64%-89% underwent regular transfusions at intervals of between 2 and 4 weeks. Transfusion-associated complications that were reported included iron overload, transfusion reactions, alloimmunization, and infections. Analyses of 42, 25, and 73 studies reporting liver iron concentration (median, 8.5 mg/g of dry weight [dw]; interquartile range [IQR], 4.5-11.0 mg/g dw), cardiac T2* magnetic resonance imaging (median, 27.4 ms; IQR, 26.0-30.2 ms), and serum ferritin (median, 1465.0 ng/mL; IQR, 1238.2-1797.0 ng/mL), respectively, showed wide ranges in iron levels and a general trend toward improved iron control in recent years. Adverse transfusion reactions and alloimmunization were reported in ~50% and 10%-20% in patients, respectively. Rates of transfusion-transmitted infections were highly variable by study but were lower in more recent cohorts. Complications stemming from iron overload and underlying disease captured in this SLR included cardiac disease, liver disease, and endocrine and musculoskeletal disorders. Approximately 10% of patients were diagnosed with heart failure, with rates ranging from 2.9% to 20.9% across 6 studies. Other significant complications reported with beta-thalassemia included pain (25%-69%), psychiatric disorders (25%-30%), and reduced health-related quality of life. Despite substantial improvements in survival, patients with TDT remained at an increased risk for early mortality. IMPLICATIONS Consistent with improvements in transfusion practices and iron monitoring and management, outcomes in patients with TDT have improved. However, iron overload and disease-associated complications remain a challenge in this population. This review supports the burden of disease affecting patients with beta-thalassemia and provides a baseline health status against which to assess future improvements in care.
