Advanced Hepatocellular Carcinoma in Adults Without Cirrhosis: A Single-Institution Retrospective Review.

Background: Although up to one in five cases of hepatocellular carcinoma (HCC) occurs in patients without cirrhosis, there is scarce literature characterizing non-cirrhotic HCC (NCHCC). Existing NCHCC research is primarily limited to surgical case series and there is a lack of data on unresectable NCHCC. Aim: The purpose of this retrospective review was to compare the characteristics of unresectable NCHCC and cirrhotic hepatocellular carcinoma (CHCC). Methods: A retrospective chart review of adult patients with unresectable HCC treated from 2007 to 2017 was performed at the University of Florida Shands Hospital. The data set was stratified into two cohorts: NCHCC and CHCC. Continuous variables were compared using Wilcoxon-Mann-Whitney tests and Kruskal-Wallis rank-sum tests. Categorical variables were compared using Pearson's Chi-squared tests and Fisher's exact tests. Overall survival was explored utilizing the Kaplan-Meier and log-rank method. Results: There were 1494 adult patients included in the final analysis, including 264 patients (17.7%) with NCHCC and 1230 patients (82.3%) with CHCC. Median age was 61.0 years old and median follow-up time was 30.2 months. NCHCC patients were older than CHCC patients (66.3 years vs 61.9 years; p < 0.0001). NHCC tumors were larger than CHCC tumors (7.92 ± 4.85 vs 4.38 ± 3.12 cm; p < 0.0001) and more likely to be associated with distant metastases (23.35% vs 15.91%; p = 0.0055). There was no difference in overall survival, with a median of 23.5 months in NCHCC and 22.4 months in CHCC (p = 0.9196). Conclusion: Our findings suggest that unresectable NCHCC and CHCC have unique characteristics but similar overall survival. To the best of our knowledge, this is the largest comparison of CHCC and NCHCC.

Frequency of technical success of two-dimensional ultrasound shear wave elastography in a large pediatric and young adult cohort: a clinical effectiveness study.

BACKGROUND: There is a paucity of available literature describing the frequency of technical success of liver two-dimensional (2-D) ultrasound (US) shear wave elastography (SWE) in children and young adults. OBJECTIVE: To determine the frequency of technical success of liver 2-D ultrasound (US) SWE in children and young adults based on the interquartile range (IQR)/median of 10 shear wave speed (SWS) measurements. MATERIALS AND METHODS: Clinical 2-D US SWE exams performed between February 2016 and March 2018 were retrospectively identified. Patient age and gender, median/mean liver stiffness (10 SWS measurements), IQR/median, abdominal wall thickness, body mass index (BMI) and serum alanine aminotransferase (ALT) were documented. The number of technically inadequate exams was calculated using three methods: 1) IQR/median >0.3, 2) IQR/median >95th percentile for our study population and 3) statistical outlier identification using the Tukey method. The effect of age, gender, median SWS, abdominal wall thickness, BMI, US transducer and ALT on measurement variability (IQR/median) was assessed using multivariable linear regression. RESULTS: During the study period, 573 exams were performed. Mean age was 12.6±7.1 years; 274 (47.8%) exams were in male patients. Average median liver stiffness was 1.75±0.47 m/s. Based on Methods 1, 2 and 3, 29/573 (5.1%), 28/573 (4.9%, IQR/median cutoff value=0.303) and 30/573 (5.2%) exams were technically inadequate. Predictors of IQR/median included age (P=0.03), abdominal wall thickness (P=0.003), median SWS (P<0.0001) and transducer (P<0.0001). CONCLUSION: Approximately 95% of liver 2-D US SWE exams are technically successful based on IQR/median in children and young adults.

Meta-analyses of HIV prevention interventions targeting improved partner communication: effects on partner communication and condom use frequency outcomes.

Behavioral HIV prevention interventions designed to improve safer-sex communication skills with sexual partners may enhance engagement in protective behaviors and reduce HIV/STI risk. The current meta-analyses examined the efficacy of individual-based (i.e., not couples-based) HIV prevention interventions with a partner communication skills building component to increase frequency of: (a) safer-sex communication and (b) condom use with sexual partners among HIV at-risk groups (e.g., heterosexual African American females). Studies were retrieved from online bibliographic databases, a database of effective behavioral HIV prevention interventions, and an existing review of effective interventions. Eight manuscripts (k = 10 intervention vs. control comparisons) met inclusion criteria. Results indicated that compared to control conditions, at post-intervention follow-up, participants who were exposed to individual-based HIV prevention interventions with safer-sex communication skills training components had safer sex discussions with partners more frequently [drandom = 0.35 ± 0.10, p < .001, 95% CI (0.16, 0.55)], and used condoms more frequently [drandom = 0.39 ± 0.07, p < .001, 95% CI (0.25, 0.54)]. Including partner communication skills training in individual-based HIV prevention interventions may increase the frequency of both partner communication and condom use among the at-risk populations represented in the meta-analyses.

The Association between Alcohol and Sexual Risk Behaviors among College Students: A Review.

PURPOSE OF REVIEW: Alcohol use is prevalent among college students and may contribute to sexual risk behavior engagement. A narrative review of the recent empirical literature examining the association between alcohol use and sexual risk behaviors among college student samples was conducted. The purpose of this review was to: (a) review studies examining the association between alcohol use and risky sexual behaviors; and (b) overview research investigating alcohol expectancies and partner characteristics as factors that may influence the alcohol-risky sex relation among college students. RECENT FINDINGS: Findings regarding the direct link between alcohol use and sexual risk behaviors were mixed. Results suggest a more nuanced association between alcohol and risky sexual behaviors that is influenced by alcohol expectancies and partner characteristics. SUMMARY: Results highlight the importance of considering additional factors that may influence the alcohol-risky sex relation. Future interventions targeting alcohol-related sexual risk behavior engagement among college students are needed.
