There are approximately 11.1 million undocumented immigrants in the United States, with a majority being Latino. Cancer is now the leading cause of death in Latinos. There is little research guiding providers on how to deliver optimal end-of-life care in this population. We describe a case of an undocumented Latino patient with advanced cancer, and provide a review of the literature on end-of-life care in undocumented immigrants. Our patient encountered many challenges as he navigated through the healthcare system in the last months of life. These included delayed diagnosis, limited social support, financial issues, fear of deportation, and language and cultural barriers, which resulted in significant physical and psychological distress. Within the undocumented patient population, there is often a lack of advance care planning, prognostic understanding, mistrust, religious practices, and cultural beliefs that may affect decision making. Given the growing number of undocumented immigrants in the United States, it is important for clinicians and policy makers to have a better understanding of the issues surrounding end-of-life care for undocumented immigrants, and work together to improve the quality of life and quality of end-of-life care for these disadvantaged individuals.

BACKGROUND: There is scant evidence to guide the management of patients after hepatic artery embolization (HAE). We examined length of stay (LOS), laboratory patterns, medication usage, morbidity, and mortality of patients hospitalized after HAE for metastatic neuroendocrine tumors. METHODS: Data were abstracted retrospectively from electronic medical records on LOS, liver function tests (LFTs), i.v. antibiotics, analgesia, peak temperature, bacteremia, hepatic abscess formation, carcinoid crisis, and metastatic burden on cross-sectional imaging. RESULTS: In 2005-2009, 72 patients underwent 174 HAEs for carcinoid and islet cell tumors. The median LOS was 4 days (range, 1-8 days). There was no correlation between peak LFTs and tumor burden. Declines in LFTs were not uniform before hospital discharge; 25%, 37%, 30%, 53%, and 67% of patients were discharged before their respective aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, and total and direct bilirubin levels began to decline, with no readmissions for acute hepatic failure. The median i.v. analgesia dose was 60 mg oral morphine equivalents (range, 3-1,961 mg). Pre-HAE i.v. antibiotics were administered in 99% of cases; post-HAE fever occurred in 37% of patients, with no documented bacteremia. One patient developed a hepatic abscess after HAE. There were two carcinoid crises. The single in-hospital death was associated with air in the portal veins. CONCLUSIONS: The duration and intensity of in-hospital care following HAE should be managed on an individual basis. A downward trend in LFTs is not required before discharge. Modest use of i.v. analgesia suggests that many patients could exclusively receive oral analgesics. Given the rarity of serious complications, hospital stays could be shortened, thereby reducing costs and nosocomial risks.

In the olfactory epithelium (OE), generation of new neurons by neuronal progenitors is inhibited by a signal from neurons themselves. Here we provide evidence that this feedback inhibitory signal is growth and differentiation factor 11 (GDF11). Both GDF11 and its receptors are expressed by OE neurons and progenitors, and GDF11 inhibits OE neurogenesis in vitro by inducing p27(Kip1) and reversible cell cycle arrest in progenitors. Mice lacking functional GDF11 have more progenitors and neurons in the OE, whereas mice lacking follistatin, a GDF11 antagonist, show dramatically decreased neurogenesis. This negative autoregulatory action of GDF11 is strikingly like that of its homolog, GDF8/myostatin, in skeletal muscle, suggesting that similar strategies establish and maintain proper cell number during neural and muscular development.
