ABSTRACT

INTRODUCTION: The prevalence of coronary artery disease (CAD) is high among patients with cirrhosis; however, the impact of it on cardiovascular disease (CVD) is not known. The aim of the current study was to evaluate CVD events in patients with cirrhosis and impact of cirrhosis on biomarkers of atherogenesis. METHODS: The study included 682 patients with decompensated cirrhosis referred for liver transplantation (LT) evaluation between 2010 and 2017. All patients were followed until they experienced a CVD event, non-cardiac death, liver transplantation or last follow-up. To evaluate mechanistic link, patients with NASH cirrhosis were propensity matched 1:2 to non-cirrhosis NASH patients and biomarkers of atherogenic risk were compared. RESULTS: The composite CVD outcome occurred in 23(3.4%) patients after a median follow-up period of 585 days (IQR 139, 747). A strong association between presence of any CAD and CVD event was noted (HR = 6.8, 95% CI 2.9, 15.9) that was independent of age, gender, BMI, and MELD score. In competing risk model, the combined rate of LT and non-cardiac was significantly higher when compared to the rate of CVD events. Marker of insulin resistance and inflammation-related markers were similar in patients with and without cirrhosis. Patients with cirrhosis were more likely to have reduced VLDL, sdLDL-C, LDL-C, and triglycerides. Interestingly, patients with cirrhosis had an increase in serum HDL-2, the anti-atherogenic lipoprotein, and adiponectin, a protective serum adipokine. CONCLUSION: The risk of CVD events in patients with cirrhosis is low and may potentially be due to improvement in markers of atherogenic risk.

ABSTRACT

INTRODUCTION: High-energy mechanisms of acetabular fracture in the geriatric population are becoming increasingly common as older adults remain active later in life. This study compared outcomes for high- versus low-energy acetabular fractures in older adults. MATERIALS AND METHODS: We studied outcomes of 22 older adults with acetabular fracture who were treated at a level-I trauma center over a 4-year period. Fourteen patients were categorized as low-energy mechanism of injury, and 8 were identified as a high-energy mechanism. We analyzed patient demographics with univariate logistic regressions performed to assess differences in high- and low-energy group as well as patient characteristics compared with surgical outcomes. RESULTS: Most high-energy mechanisms were caused by motor vehicle collision (n = 4, 50.0%), with most having posterior wall fractures (50.0%). Among patient characteristics, the mechanism of injury, hip dislocation, fracture types, and fracture gap had the largest differences between energy groups effect size (ES: 2.45, 1.43, 1.36, and 0.83, respectively). The high-energy group was more likely to require surgery (odds ratio [OR] = 2.80, 95% CI: 0.26-30.70), develop heterotopic bone (OR = 4.33, 95% CI: 0.33-57.65), develop arthritis (OR = 3.60, 95% CI: 0.45-28.56), and had longer time to surgery (mean = 4.8 days, standard deviation [SD] = 5.8 days) compared to low-energy group (mean = 2.5 days, SD = 2.3 days). DISCUSSION: The results of this case series confirm previous findings that patients with high-energy acetabular fractures are predominantly male, younger, and have fewer comorbidities than those who sustained low-energy fractures. Our results demonstrate that the majority of the high-energy fracture patients also suffered a concurrent hip dislocation with posterior wall fracture and experienced a longer time to surgery than the low-energy group. CONCLUSION: Geriatric patients who sustained high-energy acetabular fractures tend to have higher overall rates of complications, including infection, traumatic arthritis, and heterotopic bone formation when compared with patients with a low-energy fracture mechanism.

ABSTRACT

INTRODUCTION: There has been a recent trend in medical research towards a more collaborative relationship between statisticians and clinical investigators. This has led to an increased focus on the most efficient and effective ways to structure, conduct, and measure the impact of organizations that provide statistical services to clinical investigators. Several recent guidelines and recommendations on the conduct of statistical consulting services(SCSs) have been made in response to this need, focusing on larger SCSs consisting primarily of faculty and staff statisticians. However, the application of these recommendations to consulting services primarily staffed by graduate students, which have the dual role of providing a professional service and training, remains unclear. METHODS: Guidelines and recommendations, primarily from the Clinical and Translational Science (CTSA) consortium, were applied to a SCS staffed primarily by graduate students in an academic health center. A description of the organizational structure and outcomes after 3 years of operation is presented. RESULTS: The guidelines recommended by the CTSA consortium and other groups were successfully incorporated into the graduate consulting laboratory. At almost one new project request per week, the consulting laboratory demonstrated a large bandwidth and had an excellent feedback from investigators. CONCLUSIONS: Guidelines developed for larger statistical consulting organizations are able to be applied in student-led consultation organizations. Outcomes and recommendations from 3.5 years of operation are used to describe the successes and challenges we have encountered.

ABSTRACT

Cardiovascular disease (CVD) is a major contributor to longterm mortality after liver transplantation (LT) necessitating aggressive modification of CVD risk. However, it is unclear how coronary artery disease (CAD) and the development of dyslipidemia following LT impacts clinical outcomes and how management of these factors may impact survival. Patients undergoing LT at Virginia Commonwealth University from January 2007 to January 2017 were included (n = 495). CAD and risk factors in all potential liver transplantation recipients (LTRs) over the age of 50 years were evaluated via coronary angiography. The impact of pre-LT CAD after transplantation was evaluated via a survival analysis. Additionally, factors associated with new-onset dyslipidemia, statin use, and mortality were assessed using multiple logistic regression or Cox proportional hazards models. The mean age of the cohort was 55.3 ± 9.3 years at the time of LT, and median follow-up was 4.5 years. CAD was noted in 129 (26.1%) patients during the pre-LT evaluation. The presence or severity of pre-LT CAD did not impact post-LT survival. Dyslipidemia was present in 96 patients at LT, and 157 patients developed new-onset dyslipidemia after LT. Statins were underused as only 45.7% of patients with known CAD were on therapy. In patients with new-onset dyslipidemia, statin therapy was initiated in 111 (71.1%), and median time to initiation of statin therapy was 2.5 years. Statin use conferred survival benefit (hazard ratio, 0.25; 95% confidence interval, 0.12-0.49) and was well tolerated with only 12% of patients developing an adverse event requiring the cessation of therapy. In conclusion, pre-LT CAD did not impact survival after LT, potentially suggesting a role of accelerated atherosclerosis that may not be captured on pre-LT testing. Although statin therapy confers survival benefit, it is underused in LTRs.

ABSTRACT

BACKGROUND & AIMS: Cardiovascular complications are major contributors to mortality at liver transplantation (LT). However, the impact of coronary artery disease (CAD) on these complications is not well-understood as the literature is limited by non-invasive assessment of CAD, which is suboptimal in patients with cirrhosis. Thus, the current study evaluated cardiovascular events at LT stratified according to the presence and severity of CAD quantified on coronary angiography. METHODS: All patients who had LT from January 2010 to January 2017 were evaluated (N = 348), but analysis was restricted to patients who had coronary angiography prior to LT (N = 283). Protocol coronary angiography was performed in all patients' ages >50 years, history of CAD, abnormal cardiac stress test or risk factors for CAD. The primary outcome was a cardiovascular composite outcome including myocardial infraction (MI), cardiac arrest, stroke, cardiac death, heart failure or arrhythmia occurring within 4 weeks after LT. RESULTS: CAD was present in 92(32.5%) patients and 32(11.3%) had obstructive CAD. During the study period, 72(25.4%) patients met the primary cardiovascular outcome, the most common being arrhythmia (N = 59 or 20.8%). Non-ST elevation MI occurred in 11(3.9%) of patients. A total of 10 deaths (3.5%) occurred, of which 6(2.1%) were attributable to cardiac death. There was no evidence of a relationship between the presence and severity of CAD and composite cardiovascular events. In multiple regression modelling, only diabetes [OR 2.62, 95%CI (1.49, 4.64), P < 0.001] was associated with the likelihood of having a cardiovascular event. CONCLUSION: Cardiovascular disease mortality is the most important contributor of early mortality after LT but is not related to the severity of CAD.

ABSTRACT

GOALS AND BACKGROUND: Two common endoscopic therapies for eradication of dysplastic Barrett's esophagus are radiofrequency ablation (RFA) and liquid nitrogen spray cryotherapy (LNC). There is no data comparing postprocedural pain. This study aimed to compare the incidence of postprocedural pain between the 2 ablation modalities. METHODS: This is a multicenter prospective study in which pain intensity scores and the presence of dysphagia were assessed immediately before and after treatment, 48 hours posttreatment and at 3 weeks posttreatment using validated instruments. RESULTS: Of 94 patients, 35 underwent LNC and 59 underwent RFA [36 with focal radiofrequency ablation (RFA-F) and 23 with circumferential radiofrequency ablation (RFA-C)]. Immediately posttreatment, patients in the LNC group reported an average Numeric Pain Scale score that was lower than in the RFA groups [LNC 0.41 vs. RFA-F 1.18 (P=0.026), LNC 0.41 vs. RFA-C 1.38 (P=0.010)]. These differences persisted at 48 hours posttreatment [LNC 0.76 vs. RFA-F 1.77 (P=0.013), LNC 0.76 vs. RFA-C 1.73 (P=0.018)]. The odds of pain after RFA were at least 5 times greater than after LNC [immediately posttreatment odds ratio, 5.26 (95% confidence interval, 1.85-14.29) and 48 h posttreatment odds ratio, 5.56 (95% confidence interval, 2.27-14.29)]. There was no difference in dysphagia after treatment in either group, at any time point (P=0.429). CONCLUSION: LNC was associated with less postprocedural pain when compared with RFA. These results help inform patients and physicians about the expected symptoms after ablative endotherapy.

ABSTRACT

BACKGROUND AND OBJECTIVE: It has been suggested that probiotics may decrease infant mortality and nosocomial infections because of their ability to suppress colonization and translocation of bacterial pathogens in the gastrointestinal tract. We designed a large double-blinded placebo-controlled trial using Lactobacillus reuteri to test this hypothesis in preterm infants. METHODS: Eligible infants were randomly assigned during the first 48 hours of life to either daily probiotic administration or placebo. Infants in the intervention group were administered enterally 5 drops of a probiotic preparation containing 10(8) colony-forming units of L reuteri DSM 17938 until death or discharge from the NICU. RESULTS: A total of 750 infants ≤ 2000 g were enrolled. The frequency of the primary outcome, death, or nosocomial infection, was similar in the probiotic and placebo groups (relative risk 0.87; 95% confidence interval: 0.63-1.19; P = .376). There was a trend toward a lower rate of nosocomial pneumonia in the probiotic group (2.4% vs 5.0%; P = .06) and a nonsignificant 40% decrease in necrotizing enterocolitis (2.4% vs 4.0%; P = .23). Episodes of feeding intolerance and duration of hospitalization were lower in infants ≤ 1500 g (9.6% vs 16.8% [P = .04]; 32.5 days vs 37 days [P = .03]). CONCLUSIONS: Although L reuteri did not appear to decrease the rate of the composite outcome, the trends suggest a protective role consistent with what has been observed in the literature. Feeding intolerance and duration of hospitalization were decreased in premature infants ≤ 1500 g.
