The impact of diabetes mellitus and glycemic control on clinical outcomes following liver transplant for hepatitis C

Hepatitis C is the leading indication for liver transplantation in the USA and recurrence is universal. The impact of preexisting diabetes, new‐onset diabetes after transplant (NODAT), and glycemic control on fibrosis progression has not been studied. This retrospective longitudinal cohort study included adult liver recipients with hepatitis C transplanted between 2000 and 2011. Patients were divided into three groups: preexisting diabetes (n = 41), NODAT (n = 59), and no diabetes (n = 103). Patients with preexisting diabetes (70%) or NODAT (59%) were more likely to develop hepatitis C recurrence (≥stage 1 fibrosis), as compared to non‐diabetics (36%, p = 0.006). There was also a trend toward a higher incidence of at least Stage 2 fibrosis (36% and 48% vs. 23%, respectively; p = 0.063). Patients with tight glycemic control had a lower rate of Stage 2 fibrosis development (78% vs. 60%, p = 0.027), while those with good control (<150 mg/dL) also had lower rates of Stage 2 fibrosis (84% vs. 62%, p = 0.004). Multivariable analysis verified a decreased rate of recurrence for patients with blood glucose <138 mg/dL (p = 0.021), after controlling for confounders. These results demonstrate that diabetes is strongly associated with an increased risk of hepatitis C virus‐related fibrosis development and glycemic control may reduce the risk and severity of recurrence.

Acute treatment of blood pressure after ischemic stroke and intracerebral hemorrhage

Blood pressure elevation in the setting of acute ischemic stroke and intracerebral hemorrhage is common. Controversy exists as to the optimal management of elevated blood pressure in this patient population. This article reviews the available clinical data that guides acute blood pressure management and how this may affect clinical outcomes. Furthermore, it examines how these data have led to controversies in their clinical application.

Precision Dosing: Public Health Need, Proposed Framework, and Anticipated Impact

“Precision dosing” focuses on the individualization of drug treatment regimens based on patient factors known to alter drug disposition and/or response. In 2015, over 8 in 10 nonfederal acute care hospitals in the United States had adopted a basic electronic health record (EHR) system,1 which will facilitate the application of precision dosing. Expanding on recent publications,2, 3 we outline the public health need, a proposed framework, and the anticipated impact for the adoption of precision dosing.

The Role of Statin Therapy in Hemorrhagic Stroke.

The 3‐hydroxy‐3‐methylglutaryl coenzyme A reductase inhibitors (statins) are the most widely utilized class of cholesterol‐lowering agents, carrying multiple indications for both primary and secondary cardiovascular risk reduction. Concern was raised by previously published post hoc analyses and observational studies that noted an increased risk of hemorrhagic stroke in patients receiving a statin. Subsequent studies have demonstrated conflicting results regarding the role of statin therapy on hemorrhagic stroke risk and patient outcomes. New evidence suggests that statins taken prior to or continued during admission for intracerebral hemorrhage (ICH) may be associated with positive outcomes. Evidence also suggests deleterious outcomes resulting from the abrupt discontinuation of statins upon hospital admission for multiple disease states including ICH. Conflicting data also exist for the use of statins following aneurysmal subarachnoid hemorrhage (aSAH). Recent evidence suggests statins started during admission for aSAH confer no additional benefit in reducing delayed ischemic neurologic deficits despite initial positive results. Larger scale evaluation of the role of statin therapy following hemorrhagic stroke is warranted. The available literature is reviewed to provide guidance for therapeutic decision making.

Hyponatremia in Patients with Spontaneous Intracerebral Hemorrhage.

Hyponatremia is the most frequently encountered electrolyte abnormality in critically ill patients. Hyponatremia on admission has been identified as an independent predictor of in-hospital mortality in patients with spontaneous intracerebral hemorrhage (sICH). However, the incidence and etiology of hyponatremia (HN) during hospitalization in a neurointensive care unit following spontaneous intracerebral hemorrhage (sICH) remains unknown. This was a retrospective analysis of consecutive patients admitted to Detroit Receiving Hospital for sICH between January 2006 and July 2009. All serum Na levels were recorded for patients during the ICU stay. HN was defined as Na <135 mmol/L. A total of 99 patients were analyzed with HN developing in 24% of sICH patients. Patients with HN had an average sodium nadir of 130 ± 3 mmol/L and an average time from admission to sodium <135 mmol/L of 3.9 ± 5.7 days. The most common cause of hyponatremia was syndrome of inappropriate antidiuretic hormone (90% of HN patients). Patients with HN were more likely to have fever (50% vs. 23%; p = 0.01), infection (58% vs. 28%; p = 0.007) as well as a longer hospital length of stay (14 (8–25) vs. 6 (3–9) days; p < 0.001). Of the patients who developed HN, fifteen (62.5%) patients developed HN in the first week following sICH. This shows HN has a fairly high incidence following sICH. The presence of HN is associated with longer hospital length of stays and higher rates of patient complications, which may result in worse patient outcomes. Further study is necessary to characterize the clinical relevance and treatment of HN in this population.

Evaluation of a comprehensive, integrated, medical service-based pharmacy practice model

Prior to 2008, the pharmacy practice model utilized by the University of North Carolina (UNC) Medical Center was a traditional central pharmacist and clinical specialist model. The department of pharmacy implemented a unique and innovative pharmacy practice model in 2008 organized around medical services. Through this medical service‐based model, all patients are now covered by a pharmacist. The objectives of this study were to evaluate the sustainability of the improvements associated with the medical service‐based pharmacy practice model at UNC Medical Center, which included pharmacist turnover, employee satisfaction and workforce engagement, resident and student involvement in patient care, and inpatient drug costs.
