Emerging evidence suggests that psychosocial factors pre-transplant predict survival in cancer patients undergoing hematopoietic stem cell transplantation (HSCT). These studies, however, typically have small sample sizes, short-term follow ups or a limited panel of medical covariates. We extend this research in a large, well-characterized sample of transplant patients, asking whether patients' perceived emotional support and psychological distress predict mortality over 2 years. Prior to transplant, 400 cancer patients (55.5% males; 82.8% White; M=50.0 years; 67.0% leukemia, 20.0% lymphoma) were interviewed by a social caseworker, who documented the patients' perceived emotional support and psychological distress. Subsequently, patients received an allogeneic HSCT (51.0% matched-related donor, 42.0% matched-unrelated donor and 7.0% cord blood). HSCT outcomes were obtained from medical records. Controlling for demographic characteristics (age, sex, race/ethnicity and marital status) and medical confounders (disease type, conditioning regimen, remission status, cell dosage, donor and recipient CMV seropositivity, donor sex, comorbidities and disease risk), ratings of good emotional support pre-transplant predicted longer overall survival (hazard ratio (HR)=0.61, 95% confidence interval (CI), 0.42-0.91; P=0.013). Pre-transplant psychological distress was unrelated to survival, however (Ps>0.58). Emotional support was marginally associated with lower rates of treatment-related mortality (HR=0.58, CI, 0.32-1.05; P=0.073). These findings are consistent with the hypothesis that emotional support contributes to better outcomes following HSCT. Future studies should examine whether intervention efforts to optimize emotional resources can improve survival in cancer patients.

There is a high incidence of atrial fibrillation (AF) in patients with obstructive sleep apnea (OSA). Whether this represents a causative relationship or is merely an association remains to be determined. This review describes the current understanding of pathophysiologic links supporting a causative relationship between OSA and AF. The management of AF with antiarrhythmics, cardioversion and ablation success depends on compliance with OSA treatment. OSA worsens every risk factor resulting in a higher stroke risk in AF patients. Strategies for early screening and compliance with OSA treatment are the need of the hour.

Women have a similar lifetime prevalence of non-valvular atrial fibrillation (NVAF) compared with that of men. Given the significant morbidity and potential mortality associated with NVAF, it is crucial to understand gender differences with NVAF. Women can be more symptomatic than men. Despite a higher baseline stroke risk, they are less likely to be on anticoagulation. Women have a greater risk of thromboembolism and a similar rate of bleeding risk compared with men on anticoagulation. Initial experience suggests that novel oral anticoagulants have similar safety and efficacy profile in men and women. Although women can have more adverse reactions from antiarrhythmic therapies, they are often referred later than men for ablation. As a group, a mitigating factor in ablation referral is that women also have a higher incidence of procedural complications from catheter ablation. This review summarizes the available literature highlighting significant gender-based differences and also highlights areas for research to improve NVAF outcomes in women.
