Introduction: Barrett's esophagus (BE) is a metaplastic change in the distal esophagus in which squamous epithelium is replaced by columnar epithelium with goblet cells. Chronic gastroesophageal reflux disease (GERD) is strongly linked to the development of BE, which is a known precursor lesion to esophageal adenocarcinoma (EAC). There is no universal guideline for BE screening, however AJG suggest a single screening endoscopy in patients with chronic GERD symptoms and 3 or more addition risk factors, such as male sex, age > 50 years, white race, tobacco smoking, obesity and family history of BE or EAC. Within the Veteran's Affair (VA) hospital in Northport, New York, many veterans possess multiple risk factors for BE. Residents in VA primary care clinic are diligent in colorectal cancer screening, yet there is concern for limited offerings for BE screening. Our project aims to study the barriers to BE screening within a high-risk veteran population. Method(s): This is a survey-based study. A total of 36 internal medicine residents working in VA primary care clinic were asked to fill out a survey regarding their perspective towards BE screening. The results of the survey are compiled in Table. Result(s): 36 residents within the clinic completed the survey. As shown in Table, 35 out of 36 residents expressed that the primary care clinic does not screen for BE adequately. 30 residents expressed uncertainty regarding referral criteria for BE screening, 24 residents revealed having never referred patients for BE screening. When asked about barriers regarding BE screening, consensus polling showed that there is a lack of resident education surrounding indications for screening. Other common barriers include lack of transportation for veterans to appointments, the COVID 19 pandemic, and lack of health literacy within the veteran population. Conclusion(s): Although there is no established guideline for BE screening, per AJG there is recommendation for a one-time screening endoscopy in susceptible population. VA patients pose a high-risk population that appears to have low screening rates. Patients appear to be placed on long term PPIs without re-assessment and endoscopic screening despite possessing multiple risk factors for BE. Our survey shows that within our resident cohort there is concern for lack of awareness regarding screening criteria for BE. With the initiation of this project, we hope to increase awareness of BE screening within the resident group and improve health outcomes within veteran population. (Table Presented).

We examine the high-frequency intraday return and volatility transmission between crude oil futures prices and exchange rates during the 2020 Covid-19 pandemic in the context of two markets: the newly established renminbi-denominated Shanghai International Energy Exchange in China and the US-dollar-denominated Brent market in the United Kingdom. By controlling for the influence of the stock markets, our findings reveal significant disparities in return linkages, yet fairly comparable volatility transmission patterns. The International Energy Exchange shows no return linkages with exchange rates except before the shock, while Brent consistently shows return spillovers from crude oil futures prices to exchange rates. In both markets, the volatility spillovers from exchange rates to crude oil futures prices are unidirectional prior to the shock but become bidirectional as a result of the shock. Nevertheless, both the return and volatility spillover patterns in China resemble those in the United Kingdom when utilizing offshore instead of onshore exchange rates. Such similarities in return and volatility spillovers can also be observed during the 2022 Covid-19 shock that emerged in Shanghai. These findings have significant practical implications. © Infopro Digital Limited 2023.

As society faces more crises, it is critical for leaders, especially at the local level, to make decisions and intervene before reaching the tipping point. This often requires collective sensemaking across boundaries, but most studies focus on the challenges. This article asks how decision makers make timely decisions. It presents an institutions-process framework and analyzes the process and mechanism in the case of the response of E-Zhong City-just over an hour's drive from Wuhan City in Hubei Province-to COVID-19 in the "Golden Seven Days" of 2020. Decision makers achieved timely decisions by exploiting all possible political opportunities and institutional tools, maximizing the diversity of the information available, and using multiple discourses and frameworks to enhance personal crisis awareness and achieve collective sensemaking across boundaries. This article defines the mechanism as bricolage and defines these decision makers as institution-knowledge bricoleurs. The concept of institution-knowledge bricoleurs extends the study of crisis decision making and the relationship between institutions and sensemaking.
