SummaryThe thrombotic risk with haemoglobin C trait (HbAC) or haemoglobin C disease (HbCC) is unclear. However, individuals with HbCC have demonstrated chronic haemolysis, higher blood viscosity and altered rheology when compared to individuals with wild‐type haemoglobin (HbAA). These physiological alterations may theoretically translate to increased risk of thrombosis; therefore, a systematic literature review was performed to investigate the possible association between HbAC and/or HbCC and thrombosis. Twenty‐two studies met inclusion criteria representing 782 individuals with HbAC (n = 694) or HbCC (n = 88). Fifteen studies described the presence/absence of venous thromboembolism (VTE) in patients with HbAC (n = 685) or HbCC (n = 79), while seven studies described patients with HbAC (n = 9) or HbCC (n = 9) and arterial thrombosis. Most (n = 20) studies were case reports or case series; however, two studies suggested a potential increased VTE risk with HbAC compared to HbAA in (i) all patients (OR 2.2, 95% CI: 0.9–5.5) and in (ii) pregnant individuals (RR 3.7, 95% CI 0.9–16). This review is the largest assessment of patients with HbC trait or disease and thrombosis to date; despite its limitations, the findings suggest HbC may be a predisposing risk factor to thrombosis. Prospective cohort studies are warranted to definitively elucidate the risk of thrombosis in this population.

Abstract Objectives To evaluate the gender composition of departmental chairs and program leadership of Accreditation Council for Graduate Medical Education–accredited pathology residencies and American Board of Pathology–certified subspecialty fellowships across the United States. Methods In this cross-sectional analysis, we examined the gender of individuals holding leadership positions in academic pathology in the United States. Using publicly available online data, 2 authors independently coded perceived gender (ie, man/woman/other) with 100% concordance. Results In 144 pathology residency programs, more women hold residency program director positions (52.1% [75/144]). Among 11 pathology subspecialties, women overall hold fewer fellowship program director positions (45.0% [212/471]). Among the residency-associated pathology department chair positions identified, women hold fewer positions (31.8% [42/132]). There is some geographic variation in pathology leadership gender composition when stratified using US Census regions. Conclusions Women in academic pathology departments are well represented in residency and overall fellowship program leadership but are underrepresented in department chair and certain pathology subspecialty leadership positions. The disproportionate number of women in department chair positions is observed across medical specialties, highlighting the need for improved gender equity among high-level academic medicine positions.
