Forensic anthropology is in the midst of its latest reckoning with the concept of ancestry, particularly insofar as its role in the development of biological profiles for unidentified decedents and the effects that these estimations have on broader investigative processes. As anthropologists who collaborate with forensic genomics experts, we are interested in considering how debates within anthropological circles might inform-or be informed by-detailed biogeographical ancestry estimates generated as part of forensic genomic analyses. Although such analyses are clearly rooted in the natural sciences, we believe that explorations of what practitioners and the public do with this genomic data-and how this relates to issues of identity-must ultimately be a social science pursuit. In this article, we summarize the history of the race concept in anthropology and contemporary debates about ancestry estimation occurring more specifically among forensic anthropologists. We will also review some of the literature from the emerging field of social science perspectives on genomics and identity.

The Central Belize Archaeological Survey (CBAS) was initiated in 2005 as a sub-project of the Belize Valley Archaeological Reconnaissance project (BVAR; directed by Jaime Awe) to investigate the prehistoric Maya cemetery site of Caves Branch Rockshelter. Subsequently, we began to survey other nearby cave and rockshelter sites (Hardy 2009) and to excavate the monumental civic-ceremonial centre of Deep Valley (Jordan 2008). CBAS became an independent project in 2009, with an increasing focus on sites in the neighbouring Roaring Creek Valley (Figure 1). This slight geographic shift was in part intended to expand bioarchaeological investigations to include dark zone cave contexts identified during the late 1990s by BVAR's Western Belize Regional Cave Project. In the area around these caves, we identified two large, previously unreported civic-ceremonial centres and a network of raised roads (sacbeob) connecting them and other sites. Our survey and excavations at Tipan Chen Uitz (Figure 2) have yielded evidence that it was a regional capital with ties to powerful foreign polities, as attested by the discovery of multiple carved stone monuments (Figure 3; see Andres et al. 2014; Helmke & Andres 2015; Andres et al. in press in Antiquity). We have also continued our investigations of mortuary rockshelters, including Sapodilla Rockshelter in the Caves Branch Valley.

The impacts of the COVID-19 pandemic on experiential learning have been felt by students interested in forensic anthropology casework and lab training. Without access to labs and with cancellations of courses related to hands-on learning like human osteology and forensic anthropology, students may not receive critical training necessary in their fields of interest. In this paper, we explore one potential option for engaged forensic anthropology research: the creation of skeletal research surveys that students can design and disseminate to law enforcement to better understand the nature of forensic casework in their own states. Students reported a high satisfaction rate with these survey projects and were able to build networks that helped them refine their post-graduation education and career goals. By formulating questions, creating surveys, submitting to the review board, and synthesizing data, students were able to explore forensic topics without entering a traditional lab setting during times of university lockdowns. The data from this research can be used by forensic anthropology students and professors in the future to better assist law enforcement with the identification of skeletal remains. The surveys described in this paper are easily replicated by other professors seeking to provide students with low-cost, remote forensic research opportunities.

Forensic recovery of submerged human remains may present logistical challenges for forensic anthropologists. In the case reported here, a decedent was recovered from a submerged car that could not be moved or dissembled per environmental safety standards. A recovery approach uniting forensic anthropologists, dive teams, and private contractors operating a marine venturi vacuum system resulted in a successful and nearly complete recovery.

Proton Pump Inhibitors (PPIs) are widely used in the treatment of peptic ulcer disease, Helicobacter pylori (H pylori) gastritis and gastro-esophageal reflux disease. PPIs are known to be relatively safe medications, with the most common adverse reactions reported as diarrhea, nausea, vomiting, abdominal pain and headache. Thrombocytopenia has not been found to be a significant side effect of PPI use. Furthermore, successful treatment of H pylori associated immune thrombocytopenic purpura (ITP) with PPI therapy has been reported in the literature. In clinical practice, however, PPI use has been thought to be associated with medication-induced thrombocytopenia, although the precise prevalence of this consequence has not been quantified. The purpose of this study is to determine the prevalence of thrombocytopenia in hospitalized patients treated with pantoprazole, a commonly prescribed PPI, compared to non-medicated controls. In this retrospective, case-controlled analysis, we analyzed the platelet counts of 626 patients between 18 and 80 years of age who were admitted to an urban, community-based hospital and were medicated with pantoprazole for at least three days during their hospital stay. Thrombocytopenia was defined as a drop in the platelet count to below 150,000/ml, or a drop of at least 50% from baseline. Patients who had a platelet count below 150,000/ml on admission or were hospitalized for less than 3 days were excluded from the study. A control group of 560 patients with the same inclusion criteria who had not been prescribed pantoprazole was analyzed for comparison. 626 patients were included in the study group and 560 patients in the control group. The median age was 67 years in study group, and 61 years in the control group. The mean platelet count on admission was 260,00/ml in the study group, and 257,000/ml in the control group. Of the subject group, 39 patients (6.2%) met our definition of thrombocytopenia, which was not statistically different from the 35 patients (6.2%) with thrombocytopenia in the control group (p=0.90). Our study compared patients who received PPI therapy with pantoprazole for at least three hospital days to patients without treatment. We found no difference in the rate of thrombocytopenia between hospitalized patients treated with pantoprazole and the non-medicated controls. The rate of thrombocytopenia that we observed is probably an estimate of the overall thrombocytopenia rate in hospitalized patients irrespective of specific medications. While our report did not control for variables such as concurrent medication use, comorbid illnesses, and patient demographics, we are confident that the sample size selected for this study is large enough to provide sufficient evidence that thrombocytopenia is not a significant side effect of pantoprazole therapy.
