RESUMO
Since its declaration, the COVID-19 pandemic has resulted in over 530 million cases and over 6 million deaths worldwide. Predominant clinical testing methods, though invaluable, may create an inaccurate depiction of COVID-19 prevalence due to inadequate access, testing, or most recently under-reporting because of at-home testing. These concerns have created a need for unbiased, community-level surveillance. Wastewater-based epidemiology has been used for previous public health threats, and more recently has been established as a complementary method of SARS-CoV-2 surveillance. Here we describe the application of wastewater surveillance for SARS-CoV-2 in two university campus communities located in rural Lincoln Parish, Louisiana. This cost-effective approach is especially well suited to rural areas where limited access to testing may worsen the spread of COVID-19 and quickly exhaust the capacity of local healthcare systems. Our work demonstrates that local universities can leverage scientific resources to advance public health equity in rural areas and enhance their community involvement.
RESUMO
Food waste (mis)takes are implicated as drivers of global issues including climate change, food security, environmental sustainability, and international trade. In this article, we review recent research in this area and generate a novel conceptual organization through which we can understand the theoretical underpinnings of food waste. Our framework identifies consumer (mis)perception of food safety and (mis)estimation of food for consumption as the dominant mechanisms underlying food waste and specifies a set of psychological antecedents that activate these two theoretical drivers. This dynamic conceptual lens offers a framework through which researchers might categorize extant work, frame subsequent research aimed at understanding the drivers of food waste, and design solutions aimed at curbing it.

BACKGROUND: Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a recently discovered malignancy of T-cell type, correlated with the use of silicone breast implants. It has been theorized that the etiology may be linked to bacterial growth and long-term inflammation. The afflicted patient usually presents with breast swelling due to peri-implant fluid accumulation. Currently, the diagnosis is achieved by ultrasound, biopsy and testing for certain biomarkers. Following this, the treatment is achieved by complete surgical excision, or by capsulectomy and exchange with smoother surfaced implants. The aim of this study was to identify and report 50 most cited articles related to the field of BIA--ALCL. METHODS: The Web of Science Citation Index was used to identify 325 articles pertaining to BIA-ALCL. The 50 most cited articles among these were included in this study. The title, author name, journal and year of publication, country and institute of origin, level of evidence (LoE), type of study (clinical or basic), and topic of study (pathophysiology, oncologic management, diagnosis, case report and case series) were recorded. RESULTS: This study includes articles from the period 1997-2018 with an average citation rate of 65.5. The majority of the top cited articles (36%; N = 18) were found to be case reports, followed by case series (18%; N = 9), systemic reviews (12%; N = 6) and studies focused on the pathophysiology (16%; N = 8), oncologic management (6%; N = 3), databases (6%; N = 3), diagnostics (4%; N = 2) and informed consent (2%; N = 1). The articles were published across 30 journals and originated from 35 institutes. The United States was found to be the country of origin of most of the studies. While none of the articles achieved LoE 1, many were found to have LoE 4 (N = 11) or 5 (N = 19). Most of the articles (N = 42), were clinical research studies. CONCLUSION: According to this citation analysis, a large fraction of the existing high impact literature on BIA-ALCL is focused on disease monitoring. Through this study, we hope to present a simple educational tool to better appreciate the research in this relatively young field.
