RESUMEN
The development of multiple highly effective and safe direct-acting antivirals to treat hepatitis C virus (HCV) has resulted in greater ease and confidence in managing HCV infection in transplant recipients that in turn has impacted the solid organ transplant community as well. In the United States, the opioid epidemic has increased the number of overdose deaths with a concomitant increase in younger HCV viremic donors after brain death being identified. At the same time, a decrease in HCV viremic transplant candidates has led to a growing interest in exploring the use of HCV viremic liver and kidney donor allografts in HCV-negative recipients. To date, experience with the use of HCV viremic liver and kidney allografts in HCV-negative recipients is limited to a few small prospective research trials, case series, and case reports. There are also limited data on recipient and donor selection for HCV viremic liver and kidney allografts. In response to this rapidly changing landscape in the United States, experts in the field of viral hepatitis and liver and kidney transplantation convened a meeting to review current data on liver and kidney recipient selection and developed consensus opinions related specifically to recipient and donor selection of HCV viremic liver and kidney allografts.

Corticosteroids have been a mainstay of immunosuppression following liver transplantation. However, evolution in the field of transplant immunology has produced steroid-free options, resulting in most transplant centers weaning steroids after transplant within days to months-an evidence-based management decision. Patients with autoimmune hepatitis (AIH), however, receive corticosteroids prior to transplant. This raises the question of whether these patients should also be weaned from corticosteroids. In this review, we discuss the benefits of avoiding steroid use in this population of patients-an approach that not only avoids the adverse effects of corticosteroids but does so without risking graft failure from recurrent AIH or from acute cellular rejection.

BACKGROUND: Prospective and longitudinal studies have examined liver donors' medical outcomes beyond the first 1 to 2 years postdonation. There is no analogous longitudinal evidence on long-term psychosocial outcomes, including patient-reported clinically significant mental health problems and perceptions of physical well-being. We examined prevalence, descriptive characteristics, and predictors of diagnosable mental health conditions and self-reported physical health problems, including fatigue and pain, in the long-term years after liver donation. METHODS: Donors from 9 centers who initially completed telephone interviews at 3 to 10 years postdonation (mean, 5.8 years; SD, 1.9) were reinterviewed annually for 2 years using validated measures. Outcomes were examined descriptively. Repeated-measures regression analyses evaluated potential predictors and correlates of outcomes. RESULTS: Of 517 donors initially interviewed (66% of those eligible), 424 (82%) were reassessed at least once. Prevalence rates of major depression and clinically significant pain were similar to general population norms; average fatigue levels were better than norms. All prevalence rates showed little temporal change. Anxiety and alcohol use disorder rates exceeded normative rates at 1 or more assessments. Longer postdonation hospitalization, female sex, higher body mass index, concerns about donation-related health effects, and burdensome donation-related financial costs were associated with increased risk for most outcomes (P's < 0.05). Men were at higher risk for alcohol use disorder (P < 0.001). CONCLUSIONS: Anxiety and alcohol use disorders were more common than would be expected; they may warrant increased research attention and clinical surveillance. Surveillance for long-term problems in the areas assessed may be optimized by targeting donors at higher risk based on identified predictors and correlates.

Construction activities around Campeche's central park led to the discovery of an early colonial church and an associated burial ground, in use from the mid-16th century AD to the late 17th century. Remains of some individuals revealed dental mutilations characteristic of West Africa. Analyses of strontium isotopes of dental enamel from these individuals yielded unusually high (87)Sr/(86)Sr ratios, inconsistent with an origin in Mesoamerica, but consistent with an origin in West Africa in terrain underlain by the West Africa Craton, perhaps near the port of Elmina, a principal source of slaves for the New World during the 16th century. These individuals likely represent some of the earliest representatives of the African Diaspora in the Americas.

Petrographic thin sections of pottery from five Formative Mexican archaeological sites show that exchanges of vessels between highland and lowland chiefly centers were reciprocal, or two-way. These analyses contradict recent claims that the Gulf Coast was the sole source of pottery carved with iconographic motifs. Those claims were based on neutron activation, which, by relying on chemical elements rather than actual minerals, has important limitations in its ability to identify nonlocal pottery from within large data sets. Petrography shows that the ceramics in question (and hence their carved motifs) have multiple origins and were widely traded.
