Quality of life in transfusion-dependent thalassemia patients

Objectives: Thalassemia is the most common genetic disorder in the Mediterranean region. Despite recent advances in the management of thalassemia, people living in developing countries do not receive satisfactory treatment. For such chronic conditions, not only is patients' survival important but their quality of life (QOL) is also important, which is primarily driven by psychological and social constraints. This study explores various factors that affect QOL in transfusion-dependent thalassemia patients. Methods: This case control study included children with thalassemia major who received regular transfusions for the last five years. Controls were matched for age, gender and socio-economic status and included only healthy children. Different types of QOL were assessed using the World Health Organization (WHO) Quality of Life Assessment tool. Results: Our study included 90 cases (8 dropouts) and 98 controls (0 dropouts), with an average age of 8.3 ± 4.4 in cases and 12.2 ± 4.7 in the control group. The total mean aggregate score of all patient questions was 82.04 ± 15.54; in the control group, the score was 87.86 ± 12.9. In nearly all factors, differences between cases and controls were most significant in males. There were no significant differences for the variables of physical pain, appearance and relations with others in both groups. Conclusion: Although there was no significant difference in the QOL score in thalassemia children, a more significant difference was observed in male patents than in females. The implications of this finding must be explored in further case-control studies

SARS-CoV-2 vaccination modelling for safe surgery to save lives: Data from an international prospective cohort study

Background: Preoperative SARS-CoV-2 vaccination could support safer elective surgery. Vaccine numbers are limited so this study aimed to inform their prioritization by modelling. Methods: The primary outcome was the number needed to vaccinate (NNV) to prevent one COVID-19-related death in 1 year. NNVs were based on postoperative SARS-CoV-2 rates and mortality in an international cohort study (surgical patients), and community SARS-CoV-2 incidence and case fatality data (general population). NNV estimates were stratified by age (18-49, 50-69, 70 or more years) and type of surgery. Best- and worst-case scenarios were used to describe uncertainty. Results: NNVs were more favourable in surgical patients than the general population. The most favourable NNVs were in patients aged 70 years or more needing cancer surgery (351; best case 196, worst case 816) or non-cancer surgery (733; best case 407, worst case 1664). Both exceeded the NNV in the general population (1840; best case 1196, worst case 3066). NNVs for surgical patients remained favourable at a range of SARS-CoV-2 incidence rates in sensitivity analysis modelling. Globally, prioritizing preoperative vaccination of patients needing elective surgery ahead of the general population could prevent an additional 58 687 (best case 115 007, worst case 20 177) COVID-19-related deaths in 1 year. Conclusion: As global roll out of SARS-CoV-2 vaccination proceeds, patients needing elective surgery should be prioritized ahead of the general population
