RESUMEN
BACKGROUND: Obesity and metabolic syndrome (MetS) have been implicated as rising risk factors for the development of colorectal cancers. A rapid increase in the prevalence of obesity and severe obesity among Hispanic patients in the United States may present substantially increased risk for advanced colorectal neoplasia in this population. Currently, there is very little research in this area. AIMS: We sought to identify metabolic risk factors for advanced adenomas (AA) in Hispanic Americans. METHODS: We retrospectively reviewed data from the Los Angeles General (LAG) Medical Center of asymptomatic Hispanic patients above 45 years of age who underwent their first colonoscopies following a positive screening FBT. Patient demographics, metabolic characteristics, as well as colon polyp size and histology were recorded. Polyps were classified as adenomas or AA (including both high-risk adenomas and high-risk serrated polyps). Relative risk for AA was assessed by multivariate logistical regression analyses. RESULTS: Of the 672 patients in our study, 41.4% were male, 67% had adenomas, and 16% had AA. The mean BMI was 31.2 kg/m2. The mean HDL-C was 49.5 mg/dL (1.28 mmol/L) and the mean triglyceride level was 151 mg/dL. 44.6% had diabetes and 64.1% had hypertension. When comparing patients with AA to patients with no adenoma, male sex, BMI > 34.9 kg/m2, and elevated fasting triglyceride levels were associated with an increased risk of AA. FIB-4 ≥1.45 was also associated with an increased risk of AA in males. There was no significant difference in the risk of AA with diabetes, hypertension, FIB-4 score, LDL-C level, and HDL-C level. CONCLUSIONS: Hispanic patients with a positive FBT were observed to have a high incidence of AA. Class II obesity (BMI ≥ 35 kg/m2), elevated triglyceride levels were identified as risk factors among males in our study. Early interventions to address these modifiable risk factors in at-risk populations, such as multi-disciplinary weight management programs for the treatment of obesity and related co-morbidities, could potentially lead to risk reduction and CRC prevention.

Purpose of review: Bariatric and metabolic endoscopic therapies provide an option for patients seeking clinically significant weight loss with fewer adverse events than conventional bariatric surgery. Our aims are to provide an overview of the current state of primary endoscopic treatment options for weight loss and to emphasize the importance of including these therapies when presenting weight loss options to qualified patients. Recent findings: Bariatric endoscopy procedures are associated with a lower adverse event rate when compared to bariatric surgery and result in more weight loss than most existing pharmacotherapies approved by the Food and Drug Administration. Summary: Sufficient evidence exists to implement bariatric endoscopic therapies-namely, the intragastric balloon and endoscopic sleeve gastroplasty-as safe and effective treatment options for weight loss when used in combination with lifestyle changes. However, bariatric endoscopy remains an underutilized option by weight management providers. Future studies are needed to identify patient and provider-level barriers to adopting endoscopic bariatric therapies as an option for the treatment of obesity.
RESUMEN
BACKGROUND: Psychiatric co-morbidities are thought to deter listing of patients with acetaminophen-induced acute liver failure (APAP-ALF) for liver transplantation (LT). We examined the listing process and short-term outcomes via a cohort study of APAP-ALF patients with and without psychiatric comorbidity. METHODS: We analyzed listing determinants, listing rates, and short-term (21-day) outcomes in APAP-ALF patients with and without psychiatric comorbidity (mental illness and/or substance abuse) enrolled in the ALFSG registry between 2000 and 2016. RESULTS: Of the 910 APAP-ALF patients, 801 (88%) had evidence of psychiatric comorbidity. There was no difference in listing between patients with (169/801, 21%) and without (26/109, 24%) psychiatric comorbidity (p = 0.59). Listed patients in both groups were younger with more severe admission clinical parameters than those not listed. Patients with and without psychiatric comorbidity had similar short-term outcomes: transplant rates among listed patients [57/169 (34%) vs 10/26 (39%), p = 0.80], spontaneous (transplant-free) survival (SS) [544/801 (68%) vs 73/109 (67%), p = 0.93], and overall death [207/801 (26%) vs 26/109 (24%), p = 0.74]. CONCLUSIONS: In our study, which is limited by informal psychiatric assessments, psychiatric comorbidity in APAP-ALF patients does not appear to impact listing, or short-term outcomes-SS, LT, or death. Transplant listing decisions primarily appear to be based on clinical severity of disease, rather than concern that APAP-ALF patients' psychiatric comorbidity will compromise outcomes.

BACKGROUND & AIMS: Low rates of hepatocellular carcinoma (HCC) surveillance are primarily due to provider-related process failures. However, few studies have evaluated primary care provider (PCP) practice patterns, attitudes, and barriers to HCC surveillance at academic tertiary care referral centers. METHODS: We conducted a web-based survey of PCPs at 2 tertiary care referral centers (133 providers) from June 2017 through December 2017. The survey was adapted from pretested surveys and included questions about practice patterns, attitudes, and barriers to HCC surveillance. We used the Fisher exact and Mann-Whitney rank-sum tests to identify factors associated with adherence to HCC surveillance recommendations, for categoric and continuous variables, respectively. RESULTS: We obtained a provider-level response rate of 75% and clinic-level response rate of 100% (133 providers). Whereas most PCPs performed HCC surveillance themselves, one-third deferred surveillance to subspecialists and referred patients to a hepatology clinic. Providers believed the combination of ultrasound and α-fetoprotein analysis to be highly effective for early stage tumor detection and reported using the combination for assessment of most patients. However, PCPs were more likely to use computed tomography- or magnetic resonance imaging-based surveillance for patients with nonalcoholic steatohepatitis or decompensated cirrhosis. Most providers believed HCC surveillance to be efficacious for early tumor detection and increasing survival. However, they desired increased high-quality evidence to characterize screening benefits and harms. Providers expressed notable misconceptions about HCC surveillance, including the role for measurement of liver enzyme levels in HCC surveillance and cost effectiveness of surveillance in patients without cirrhosis. They also reported barriers, including not being up to date on HCC surveillance recommendations, limited time in the clinic, and competing clinical concerns. CONCLUSIONS: In a web-based survey, PCPs reported misconceptions and barriers to HCC surveillance. This indicates the need for interventions, including provider education, to improve HCC surveillance effectiveness in clinical practice.

BACKGROUND: Patients with inflammatory bowel disease (IBD) require close follow up and frequently utilize healthcare services. We aimed to identify the main reasons that prompted patient calls to gastroenterology providers and further characterize the "frequent callers". METHODS: This retrospective cross-sectional study included all phone calls registered in medical records of IBD patients during 2012. Predictive variables included demographics, psychiatric history, IBD phenotype, disease complications and medical therapies. Primary outcome was the reason for call (symptoms, medication refill, procedures and appointment issues). Secondary outcome was the frequency of changes in management prompted by the call. RESULTS: 209 patients participated in 526 calls. The mean number of calls per patient was 2.5 (range 0-27); 49 (23.4%) patients met the criterion of "frequent caller". Frequent callers made or received 75.9% of all calls. Crohn's disease, anxiety, extra-intestinal manifestations and high sedimentation rate were significantly associated with higher call volume. 85.7% of frequent callers had at least one call that prompted a therapeutic intervention, compared to 18.9% of non-frequent callers (P<0.001). The most common interventions were ordering laboratory or imaging studies (15.4%), dose adjustments (12.1%), changes in medication class (8.4%), and expediting clinic visits (8.4%). CONCLUSION: Most phone calls originated from a minority of patients. Repeated calling by the same patient and new onset of gastrointestinal (GI) and non-GI symptoms were important factors predicting the order of diagnostic modalities or therapeutic changes in care. Triaging calls to IBD healthcare providers for patients more likely to require a change in management may improve healthcare delivery.
RESUMEN
OBJECTIVE: Establish reference values of cardiorespiratory fitness applicable to the general, untrained spinal cord injury (SCI) population. DESIGN: Data were retroactively obtained from 12 studies (May 2004 to May 2012). SETTING: An institution-affiliated applied physiology research laboratory. PARTICIPANTS: A total of 153 men and 26 women (age, 18-55y) with chronic SCI (N=179) were included. Participants were not involved in training activities for 1 or more months before testing and were able to complete a progressive resistance exercise test to determine peak oxygen consumption (Vo2peak). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: Percentile ranking (poor<20%; fair; 20%-40%; average, 40%-60%; good, 60%-80%; excellent, 80%-100%) used to establish reference values. RESULTS: Reference cardiorespiratory fitness values based on functional classification as paraplegic or tetraplegic were established (paraplegic: median, 16.0mL·kg(-1)·min(-1); range, 1.4-35.2mL·kg(-1)·min(-1); tetraplegic: median, 8.8mL·kg(-1)·min(-1); range, 1.5-21.5mL·kg(-1)·min(-1)) for untrained men and women. For the primary outcome measure (Vo2peak), persons with paraplegia had significantly higher values than did persons with tetraplegia (P<.001). Although men had higher values than did women, these differences did not reach significance (P=.256). Regression analysis revealed that motor level of injury was associated with 22.3% of the variability in Vo2peak (P<.001), and an additional 8.7% was associated with body mass index (P<.001). No other measure accounted for additional significant variability. CONCLUSIONS: Established reference fitness values will allow investigators/clinicians to stratify the relative fitness of subjects/patients from the general SCI population. Key determinants are motor level of injury and body habitus, yet most variability in aerobic capacity is not associated with standard measures of SCI status or demographic characteristics.
