Cerebrovascular accident (CVA) is one of the major complications and a leading cause of death in patients with a left ventricular assist device (LVAD). Multiple studies of have shown that patients with blood stream infection (BSI) are more likely to develop CVA compared to patients without BSI. However, there is no meta-analysis to confirm this association. Studies were systematically acquired from MEDLINE and EMBASE electronic databases. Included studies assessed patients with heart failure requiring LVAD and reported the number of patients who had BSI post LVAD, incidence of ischemic CVA, hemorrhagic CVA, or any CVA. Pooled effect size was calculated with a random-effect model, weighted for the inverse of variance. Heterogeneity was assessed with I. Six studies were analyzed. Participants with LVAD who developed BSI were more likely to have a CVA compared to participants without BSI (RR 3.43, 95% CI 2.49-4.72, I = 0). In four studies, there was an association between BSI and increased incidence of hemorrhagic CVA post LVAD (RR 5.28, 95% CI 2.65-10.53) with minimal heterogeneity (I = 30%). In three studies, participants with BSI were more likely to develop ischemic CVA (RR 2.18, 95% CI 1.23-3.84) compared to patients without BSI. This meta-analysis suggested that there maybe an association between blood stream infection and cerebrovascular accident in patients with LVAD.

Objective To describe a rare case of pheochromocytoma presenting with hypoglycemia. Methods We describe a rare case of pheochromocytoma presenting with a hypoglycemic seizure. Our article includes our differentials, work up, and management. Results Our patient had non–islet-cell tumor hypoglycemia that was non-insulin mediated, as noted by low insulin levels. His hypoglycemia was likely multifactorial and mediated by different mechanisms. We describe the rare case and review the causes of tumor-induced hypoglycemia. Conclusion Pheochromocytomas can rarely present with hypoglycemia and are associated with a poor prognosis.

Non-vitamin K oral anticoagulants (NOACs) are being increasingly prescribed. These drugs act rapidly, have predictable dose-related anticoagulation effect and require no routine laboratory monitoring, making them attractive for both patients and healthcare providers. All NOACs are at least partially excreted thought the kidneys. Renal injury related to NOAC use is being increasingly reported. NOAC-related acute interstitial nephritis (AIN) has only been reported once and that was in context of dabigatran use. We describe the first case of apixaban-related AIN. This case adds an important differential diagnoses that should be considered for any patient presenting with renal injury while being treated with NOACs.
