Social determinants of health: a need for better data capture in Asian American patients with hepatocellular cancer.

BACKGROUND: Social determinants of health lead to better cancer care. This multi-site, single-institution study sought to capture data on social determinants of health data in Asian Americans with hepatocellular carcinoma; this group constitutes 60% of patients with this malignancy and are often undertreated or not treated at all. METHODS: This study took advantage of an institutional initiative designed to capture and integrate social determinants of health data into the electronic medical record for all patients. Medical records of Asian Americans with hepatocellular cancer were reviewed to acquire data on housing instability, lack of transportation, financial concerns, and social isolation; a score of 1 indicated poor social determinants of health. RESULTS: Of 112 adult Asian American patients with hepatocellular cancer, 22 (20%) were Southeast Asian, and 74 (67%) described English proficiency/preference. Total noncompletion per domain (no question answered within that domain) was observed in 90 patients (80%) for housing instability; 90 (80%) for lack of transportation; 92 (82%) for financial hardship; and 90 (80%) for social isolation. A score of 1 (highest risk) was observed in 1 patient (0.9%) for housing instability; 1 (0.9%) lack of transportation; no patient for financial hardship; and 1 (0.9%) for social isolation. Of note, institution-wide benchmark total noncompletion rates were 0.3%, 0.3%, 47%, and 39% for these respective domains. CONCLUSION: High total noncompletion rates make social determinants of health data challenging to interpret and underscore the need for evidence-based guidelines on how best to capture such data in underserved patients.

Migraine and Gastroparesis.

PURPOSEOF REVIEW: Migraine is a chronic and disabling disease affecting a significant proportion of the world's population. There is evidence that gastroparesis, a gastrointestinal (GI) dysmotility disorder in which transit of gastric contents is delayed, can occur in the setting of migraine. This article aims to review recent literature on overlap in the pathophysiology and clinical manifestations of migraine and gastroparesis and highlight management considerations when these disorders coexist. RECENT FINDINGS: There has been increasing recognition of the importance of the connection between the GI tract and the brain, and mounting evidence for the overlap in the pathophysiology of migraine and gastroparesis specifically. There exists a complex interplay between the central, autonomic, and enteric nervous systems. Studies show that gastroparesis may be present during and between acute migraine attacks necessitating modification of management to optimize outcomes. Gastric dysmotility in the setting of migraine can impact absorption of oral migraine medications and alternate formulations should be considered for some patients. Noninvasive vagus nerve stimulation has been FDA cleared for migraine treatment and is also being studied in gastroparesis. Dysfunction of the autonomic nervous system is a significant feature in the pathophysiology of gut motility and migraine, making treatments that modulate the vagus nerve attractive for future research.

Magnetic resonance elastography can discriminate normal vs. abnormal liver biopsy in candidates for live liver donation.

PURPOSE: The aim of this study was to define liver shear stiffness by magnetic resonance elastography (MRE) that distinguishes normal from abnormal liver biopsy, especially when steatosis ≥20%, among potential live liver donors. METHODS: Baseline clinical, laboratory, imaging, MRE, and liver biopsy results were recorded. Using MRE, hepatic shear stiffness in kilopascals (kPa) was measured and compared to liver biopsy. Comparison between groups was done using χ(2) or Fisher's exact test for categorical variables and Wilcoxon test for continuous variables. Receiver operating characteristic (ROC) curve was calculated to assess diagnostic accuracy. Statistical significance was set at p < 0.05. RESULTS: 38 healthy adults were included. Liver biopsy was normal in 27 and abnormal in 11. ROC curve for MRE defined optimal cutoff at 2.6 kPa (sensitivity 0.72, specificity 0.85, AUC 0.81) to distinguish these 2 groups. Hepatic steatosis ≥20% on biopsy is a contraindication for liver donation in our center. We evaluated the ability of MRE to distinguish this degree of steatosis: 8 persons had steatosis ≥20% and were excluded from donation. ROC curve for MRE defined optimal cutoff at 2.82 kPa (sensitivity 0.88, specificity 1, AUC 0.98) to identify this group. CONCLUSIONS: Liver stiffness measured by MRE, even in the absence of liver fibrosis, can be useful in differentiating normal from abnormal liver histology, and most importantly in patients under evaluation for live liver donation, can very accurately distinguish those with complicated hepatic steatosis ≥20%, our cutoff for donation. In the future, MRE might provide supplementary information to make liver biopsy unnecessary in the donor evaluation process.

Magnetic resonance elastography (MRE) in assessing hepatic fibrosis: performance in a cohort of patients with histological data.

PURPOSE: The purpose of this study was to compare fibrosis seen on liver biopsy to MR elastography (MRE) stiffness measurements in normal controls and patients with abnormal transaminases and chronic liver disease. METHODS: The control group consisted of 22 healthy liver transplant donors who by definition had normal transaminases. The patient group (32 patients) was recruited from the Mayo Clinic Arizona hepatobiliary clinic over a 3-year span. All subjects underwent a liver biopsy as part of their evaluation and agreed to MRE within 35 days of biopsy. Non-parametric tests were used to compare the MRE-predicted liver fibrosis to the fibrosis noted on liver biopsy. RESULTS: Analysis included 54 subjects (32 patients with chronic liver disease and 22 healthy liver donor candidates). MRE median liver stiffness measurements increased per histologic liver fibrosis stage (one-way ANOVA p = 0.001), with significant correlation between increasing fibrosis stage and stiffness values. Median MRE for control group (2.13 kPa; mean = 2.3 ± 0.6 kPa) was significantly lower than for patient group (3.7 kPa; mean = 4.1 ± 2.1 kPa) (p = 0.003). Significantly, lower median stiffness was seen in zero-to-moderate (F0-2, n = 22) vs. severe fibrosis stages (F3-4, n = 10) 2.80 vs. 5.9 kPa, respectively (p < 0.05). Using a 3.7-kPa cut-off value, the predicted sensitivity and specificity for detecting F0-2 from F3-4 were 91% and 80%, respectively. CONCLUSIONS: Our analysis supports previous findings that MRE is a non-invasive and effective method for detection and assessment of liver fibrosis, particularly for discrimination between F0-2 stages and F3-4 stages. MRE may represent a valuable tool to finely discern hepatic fibrosis non-invasively.

The Face of Tropical Sprue in 2010.

Tropical sprue (TS), although endemic in certain tropical regions of the world, is rarely seen in North America and Europe. However, in this era of globalization and worldwide travel, it is important for all clinicians to be aware of the possibility of TS in patients presenting with nonspecific, persistent gastrointestinal complaints like diarrhea and weight loss. The symptoms and histologic findings of TS can resemble and be confused with those of diseases seen more commonly in nontropical climates like celiac disease and small intestine bacterial overgrowth. Therefore, if the usual causes of persistent diarrhea are ruled out, keeping a high index of suspicion for TS in patients who have a travel history to one of the endemic regions is important.

Risk factors for pancreatic adenocarcinoma and prospects for screening.

Pancreatic cancer has one of the worst survival rates of any cancer and is the fourth leading cause of cancer mortality. Early detection and surgery are the patient's best chance for cure. However, symptoms are typically vague and occur when the cancer is unresectable. Population-based mass screening is not practical for this rare disease, though screening and early detection in asymptomatic high-risk patient populations may be indicated.

An intention-to-treat analysis of liver transplantation for hepatocellular carcinoma using organ procurement transplant network data.

Single-center studies have shown acceptable long-term outcomes following orthotopic liver transplantation (OLT) for hepatocellular carcinoma (HCC) when tumors are within the Milan criteria. However, the overall survival and waiting list removal rates have not been described at a national level with pooled registry data. To evaluate this, a retrospective cohort of patients listed for OLT with a diagnosis of HCC between January 1998 and March 2006 was identified from Organ Procurement Transplant Network data. Analysis was performed from the time of listing. Adjusted Cox models were used to assess the relative effect of potential confounders on removal from the waiting list as well as survival from the time of wait listing. A total of 4482 patients with HCC were placed on the liver waiting list during the study period. Of these, 65% underwent transplantation, and 18% were removed from the list because of tumor progression or death. The overall 1- and 5-year intent-to-treat survival for all patients listed was 81% and 51%, respectively. The 1- and 5-year survival was 89% and 61% for those listed with tumors meeting the Milan criteria versus 70% and 32% for those exceeding the Milan criteria (P < 0.0001). On multivariate analysis, advanced liver failure manifested by Child-Pugh class B or C increased the risk of death, while age < 55 years, meeting the Milan criteria, and obtaining a liver transplant were associated with better survival. The current criteria for liver transplantation of candidates with HCC lead to acceptable 5-year survival while limiting the dropout rate. Liver Transpl 15:859-868, 2009. (c) 2009 AASLD.
