Patients with PK deficiency have a spectrum of significant, long-term complications that include iron overload, liver disease, osteopenia/bone fragility, biliary events and pulmonary hypertension [<span>1-4</span>]. It has been reported that some of these clinical complications, including iron overload and pulmonary hypertension, are associated with a lower health-related quality of life in patients with PK deficiency [<span>5</span>]. The overlap in clinical and haematological features of PK deficiency with other hereditary anaemias, as well as its clinical heterogeneity, often hinders diagnosis of the disease [<span>6</span>]. Due to the rarity of PK deficiency and its common misdiagnosis [<span>6</span>], the current understanding of the disease burden and the impact of PK deficiency on patient survival is limited. A better understanding of survival outcomes could improve disease management, timing of treatment intervention and healthcare resource utilisation.</p><p>To better characterise the survival outcomes of these patients, this retrospective cohort study evaluated overall survival (OS) of patients with PK deficiency and matched non-PK deficiency controls in the United Kingdom (UK), using data from the Clinical Practice Research Datalink (CPRD). The CPRD is comprised of two longitudinal primary care databases, CPRD Aurum and CPRD GOLD, which cover 20% and 4% of the UK population, respectively.

Established in 2020, <i>eJHaem</i> is a relatively young journal that has already become an important publication within the BSH family of journals.</p><p>Since its inception, Dr. Andrew Evens has brilliantly led <i>eJHaem</i>. Under his guidance, the Journal has published a wide variety of content, including original articles, short reports, case reports, letters, correspondence, and striking images in haematology. The journal covers all aspects of haematology—both benign and malignant diseases, adult and paediatrics—as well as topics in cell therapy (HSCT and CAR-T) and transfusion medicine.</p><p>As Editor-in-Chief, I aim to expand the journal's reach, ensuring it becomes a truly global venue representing physicians, scientists, and researchers from diverse regions. A bit about my background: I was born in Boston and raised in São Paulo, Brazil. I returned to the United States for medical training, where I spent 15 years completing my internship, residency, chief residency, and fellowships in both haematology and oncology. For over a decade, I worked at the Haematology Branch of the National Heart, Lung, and Blood Institute (NHLBI) at the National Institutes of Health (NIH) in Bethesda, Maryland. During my fellowships at the NIH, I conducted research both at the bench and in the clinic. After this period, I returned to São Paulo in 2012 to become the Head of the Division of Haematology at one of the largest cancer centres in the country. My international experience has impacted my vision for <i>eJHaem</i>: to make it not only accessible but also truly “author-friendly” for contributors worldwide, while expanding its reach to less represented regions.</p><p>It is bittersweet to step down from my role as an Associate Editor (AE) of the <i>British Journal of Haematology</i> (<i>BJHaem</i>), where I have served since 2019. I am grateful for the warm welcome I received and for the opportunity to contribute to <i>BJHaem</i>. I particularly want to thank Dr. John Barrett, Editor-in-Chief during my tenure. With his leadership, talent, and knowledge, John excelled at enhancing the quality and breadth of <i>BJHaem</i>’s publications and assembling a truly top-notch team of Associate Editors. I would also like to express my gratitude to Lorna Wycherley, the journal's exceptional Editorial Assistant, whose efforts kept the editorial process running smoothly, and Claire Dowbekin, Wiley's senior publisher, for her openness to innovation, collaboration, and support.</p><p>As I take on this new role, I am excited to continue working alongside Dr. Andrew Evens, who is stepping into the role of Editor-in-Chief at <i>BJHaem</i>.
