Addition of [18 F]Fluorodeoxyglucose Positron Emission Tomography With Computed Tomography to Cross-Sectional Imaging Improves Staging and Alters Management in Hepatocellular Carcinoma.

In this work, we characterize the value of positron emission tomography (PET) with computed tomography (CT) in combination with cross-sectional imaging for staging and prognostication of hepatocellular carcinoma (HCC) patients. In this retrospective cohort study, HCC patients underwent PET-CT after initial staging with contrast-enhanced CT or magnetic resonance imaging (MRI). The benefit of PET-CT was measured by the identification of new HCC lesions, and potential harm was quantified by the number of false positives and subsequent diagnostic evaluation. We used multivariate Cox regression analysis to evaluate the association between the highest grade on PET-CT with the risk of extrahepatic metastasis, progression-free, and overall survival. Among 148 patients, PET-CT detected additional extrahepatic metastasis in 11.9% of treatment-naïve and 13.8% of treatment-experienced patients. PET-CT changed the Barcelona Clinic Liver Cancer (BCLC) staging in 5.9% of treatment-naïve and 18.8% of treatment-experienced patients compared with CT/MRI alone, changing HCC management in 9.9% and 21.3% of patients, respectively. Of the patients, 5% (n = 8) experienced severe physical harm requiring additional procedures to evaluate extrahepatic findings. High tumor grade on PET-CT was independently associated with a higher likelihood of extrahepatic metastasis (hazard ratio [HR], 17.1; 95% confidence interval [CI], 3.6-81.5) and worse overall survival (HR, 2.4; 95% CI, 1.4-4.3). Treatment-experienced patients (versus treatment-naïve patients; HR, 9.7; 95% CI, 1.9-49.4) and BCLC stage A (HR, 8.2; 95% CI, 1.5-45.9; P < 0.01) and BCLC stage B (HR, 20.6; 95% CI, 1.5-282.2; P < 0.05) were more likely to have an upstaging with PET-CT compared with BCLC stage C (reference). PET-CT provides prognostic information and improves tumor staging beyond CT/MRI alone, with subsequent changes in management for patients with HCC.

Use of Telehealth Expedites Evaluation and Listing of Patients Referred for Liver Transplantation.

BACKGROUND & AIMS: Liver transplantation is the only treatment that increases survival times of patients with decompensated cirrhosis. Patients who live farther away from a transplant center are disadvantaged. Health care delivery via telehealth is an effective way to manage patients with decompensated cirrhosis remotely. We investigated the effects of telehealth on the liver transplant evaluation process. METHODS: We performed a retrospective study of 465 patients who underwent evaluation for liver transplantation at the Richmond Veterans Affairs Medical Center from 2005 through 2017. Of these, 232 patients were evaluated via telehealth, and 233 via in-person evaluation. Using regression models, we evaluated the differential effects of telehealth vs usual care on placement on the liver transplant waitlist. We also investigated the effects of telehealth on time from referral to initial evaluation by a transplant hepatologist, liver transplantation, and mortality. RESULTS: Patients in the telehealth group were evaluated significantly faster than patients evaluated in person, without or with adjustment for potential confounders (21.7 vs 79.5 d; P < .01). Telehealth also was associated with a significantly shorter time on the liver transplant waitlist (138.8 vs 249 d; P < .01). After propensity-matched analysis, telehealth was associated with a reduction in the time from referral to evaluation (hazard ratio, 0.15; 95% CI, 0.09-0.21; P < .01) and listing (hazard ratio, 0.26; 95% CI, 0.12-0.40; P < .01), but not to transplantation. In the intent-to-treat analysis of all referred patients, we found no significant difference in pretransplant mortality between patients evaluated via telehealth vs in-person. There was statistically significant interaction between model for end-stage liver disease (MELD)-Na scores and time to evaluation (P = .009) and placement on the transplant waitlist (P = .002), with telehealth offering greater benefits to patients with low MELD-Na scores. CONCLUSIONS: Use of telehealth is associated with a substantial reduction in time from referral to initial evaluation by a hepatologist and placement on the liver transplant waitlist, especially for patients with low MELD scores, with no changes in time to transplantation or pretransplant mortality. More studies are needed, particularly outside of the Veterans Administration Health System, to confirm that telehealth is a safe and effective way to expand access for patients undergoing evaluation for liver transplantation.

Use and Perception of Contraception among Genders in Santo Domingo, Dominican Republic.

BACKGROUND: The prevalence of contraception in the Dominican Republic is among the highest of Latin American countries. Prior research has assessed the general perception of contraception in Latin America, examined determinants of contraceptive use among Dominican women, and explored their perceived reproductive control. Little research has explored the specific role each sexual partner, male and female, has in determining the use of contraception in Latin American countries. OBJECTIVE: This study aims to address the gap in research regarding the specific role each sexual partner has in determining the contraception use in Latin American countries by evaluating male and female perception and use of contraception, and their perceived reproductive control. METHODS: A one-time survey was administered to adult patients of two short-term medical missions located in Santo Domingo, Dominican Republic. The difference in overall responses to dichotomous questions and ordinal questions were tested using binomial Z-test and nonparametric Chi-Square Goodness-of-Fit test. Bivariate analyses were conducted using cross tabulation with Chi-Square test. FINDINGS: The majority of participants of both genders are in favor of contraception use, believe they have the power to avoid an unplanned pregnancy, and view their partners' wishes regarding the use of contraception as important. However, significantly more females than males are in favor of contraception use (p-value = 0.01). Specific subgroups of men and women answered the survey in ways that suggest traditional values may be at odds with individuals' willingness to use contraception. CONCLUSIONS: There is an overall acceptance of contraception use and perception of reproductive control among both genders in our population, with a greater proportion of females in favor of contraception use than males (p-value = 0.01). Changing cultural norms may be coming into conflict with established beliefs and practices in the Dominican Republic, such as its machismo culture.

Acute kidney injury in acute liver failure: a review.

Acute liver failure is a rare and often devastating condition consequent on massive liver cell necrosis that frequently affects young, previously healthy individuals resulting in altered cognitive function, coagulopathy and peripheral vasodilation. These patients frequently develop concurrent acute kidney injury (AKI). This abrupt and sustained decline in renal function, through a number of pathogenic mechanisms such as renal hypoperfusion, direct drug-induced nephrotoxicity or sepsis/systemic inflammatory response contributes to increased morbidity and is strongly associated with a worse prognosis. Improved understanding of the pathophysiology AKI in the context of acute liver failure may be beneficial in a number of areas; the development of new and sensitive biomarkers of renal dysfunction, refining prognosis and organ allocation, and ultimately leading to the development of novel treatment strategies, these issues are discussed in more detail in this expert review.

Independent effects of pregnancy induced hypertension on childhood development: a retrospective cohort study.

OBJECTIVE: To assess whether maternal hypertension in pregnancy was independently associated with additional support needs in children. STUDY DESIGN: Retrospective cohort study using linkage of birth records of all singleton deliveries occurring in primigravidae between 1995 and 2008 in Aberdeen Maternity and Neonatal Databank with the Support Needs System (SNS) dataset in Grampian. Crude and adjusted odds ratios with 95% confidence intervals of having a record in SNS in the presence of maternal pregnancy induced hypertension were calculated using logistic regression taking account of confounders such as preterm birth and low birth weight. RESULTS: After adjusting for confounding factors, neither pre-eclampsia {Adj OR 0.80 (95% CI 0.60, 1.07)} nor gestational hypertension {Adj OR 1.16 (95% CI 0.99, 1.36)} showed statistically significant associations with additional support needs. An association of pre-eclampsia with cerebral palsy seen on univariate analysis also disappeared on adjusting for confounders {Adj OR 1.26 (95% CI 0.43, 3.68)}. Birth before 32 weeks gestation and birthweight below 1500g were independently associated with additional support needs in children. CONCLUSIONS: While maternal hypertension was not found to be independently associated with special needs in children, very preterm birth and very low birthweight showed an association.

Effect of interpregnancy interval on outcomes of pregnancy after miscarriage: retrospective analysis of hospital episode statistics in Scotland.

OBJECTIVE: To determine the optimum interpregnancy interval after miscarriage in a first recorded pregnancy. DESIGN: Population based retrospective cohort study. SETTING: Scottish hospitals between 1981 and 2000. PARTICIPANTS: 30,937 women who had a miscarriage in their first recorded pregnancy and subsequently became pregnant. MAIN OUTCOME MEASURES: The primary end point was miscarriage, live birth, termination, stillbirth, or ectopic pregnancy in the second pregnancy. Secondary outcomes were rates of caesarean section and preterm delivery, low birthweight infants, pre-eclampsia, placenta praevia, placental abruption, and induced labour in the second pregnancy. RESULTS: Compared with women with an interpregnancy interval of 6-12 months, those who conceived again within six months were less likely to have another miscarriage (adjusted odds ratio 0.66, 95% confidence interval 0.57 to 0.77), termination (0.43, 0.33 to 0.57), or ectopic pregnancy (0.48, 0.34 to 0.69). Women with an interpregnancy interval of more than 24 months were more likely to have an ectopic second pregnancy (1.97, 1.42 to 2.72) or termination (2.40, 1.91 to 3.01). Compared with women with an interpregnancy interval of 6-12 months, women who conceived again within six months and went on to have a live birth in the second pregnancy were less likely to have a caesarean section (0.90, 0.83 to 0.98), preterm delivery (0.89, 0.81 to 0.98), or infant of low birth weight (0.84, 0.71 to 0.89) but were more likely to have an induced labour (1.08, 1.02 to 1.23). CONCLUSIONS: Women who conceive within six months of an initial miscarriage have the best reproductive outcomes and lowest complication rates in a subsequent pregnancy.
