A Systematic Review of Technical Parameters for MR of the Small Bowel in non-IBD Conditions over the Last Ten Years.

ABSTRACT: Technical guidelines for magnetic resonance imaging (MRI) of the small bowel (SB) in the setting of inflammatory bowel diseases (IBDs) were detailed in a 2017 consensus issued by European Society of Gastrointestinal and Abdominal Radiology (ESGAR) and European Society of Pediatric Radiology (ESPR); however, MRI for non-IBD conditions was not addressed. Hence, we performed a systematic review collecting researches on SB MRI for non-IBDs. The literatures were then divided into morphologic group and functional group. Information about the MRI techniques, gastrointestinal preparation, and details of cine-MRI protocols was extracted. We found that a 1.5?T MRI system, prone positioning, and MR enterography were frequently utilized in clinical practice. Gadolinium contrast sequences were routinely implemented, while diffusion-weighted imaging (DWI) was much less performed. The gastrointestinal preparation varied throughout the studies. No uniform protocols for cine imaging could be established. SB MRI examinations for non-IBDs are far from standardized, especially for functional studies. Recommendations for standard parameters in cine-MRI sequences are difficult to make due to lack of evidentiary support. MRI investigations in non-IBD conditions are needed and the standardization of non-IBD imaging in clinical practice is required.

Project description:There is an increasing need to understand the structural drivers of immigrant health inequities, including xenophobic and racist policies at the state level in the United States. Databases aggregate state policies related to immigration and research using single year indices examines state policy and immigrant health. Yet none of these sources use a theoretically informed social determinants of immigrant health approach to consider state environments longitudinally, include both exclusionary and inclusionary policies, and are relevant to immigrants from any region of the world or ethnic group. Using an established social determinants of immigrant health framework, a measure of structural xenophobia was created using fourteen policies across five domains: access to public health benefits, higher education, labor and employment, driver's licenses and identification, and immigration enforcement over a ten-year period (2009-2019). To create the Immigration Policy Climate (IPC) index, we used data from state legislatures as well as policy databases from foundations, advocacy organizations, and scholarly articles. We identified and coded 714 US state policies across the 50 US States and the District of Columbia from 2009 to 2019. We calculated annual IPC index scores (range: 12 - 12) as a continuous measure (negative scores: exclusionary; positive scores: inclusionary). Results show that the US has an exclusionary immigration policy climate at the state-level (mean IPC score of -2.5). From 2009 to 2019, two-thirds of state-level immigration policies are exclusionary towards immigrants. About 75% of states experienced a 4-point change or less on the IPC index, and no state changed from largely exclusive to largely inclusive. By aggregating comprehensive, detailed data and a measure of state-level immigration policies over time, the IPC index provides population health researchers with rigorous evidence with which to assess structural xenophobia and an opportunity for longitudinal research on health inequities and immigrant health.
