Large-scale sequencing identifies multiple genes and rare variants associated with Crohn's disease susceptibility
Genome-wide association studies (GWASs) have identified hundreds of loci associated with Crohn's disease (CD). However, as with all complex diseases, robust identification of the genes dysregulated by noncoding variants typically driving GWAS discoveries has been challenging. Here, to complement GWASs and better define actionable biological targets, we analyzed sequence data from more than 30,000 patients with CD and 80,000 population controls. We directly implicate ten genes in general onset CD for the first time to our knowledge via association to coding variation, four of which lie within established CD GWAS loci. In nine instances, a single coding variant is significantly associated, and in the tenth, ATG4C, we see additionally a significantly increased burden of very rare coding variants in CD cases. In addition to reiterating the central role of innate and adaptive immune cells as well as autophagy in CD pathogenesis, these newly associated genes highlight the emerging role of mesenchymal cells in the development and maintenance of intestinal inflammation.Large-scale sequence-based analyses identify novel risk variants and susceptibility genes for Crohn's disease, and implicate mesenchymal cell-mediated intestinal homeostasis in disease etiology.Cellular mechanisms in basic and clinical gastroenterology and hepatolog
Effect of angiotensin-converting enzyme inhibitor and angiotensin receptor blocker initiation on organ support-free days in patients hospitalized with COVID-19
IMPORTANCE Overactivation of the renin-angiotensin system (RAS) may contribute to poor clinical outcomes in patients with COVID-19.
Objective To determine whether angiotensin-converting enzyme (ACE) inhibitor or angiotensin receptor blocker (ARB) initiation improves outcomes in patients hospitalized for COVID-19.
DESIGN, SETTING, AND PARTICIPANTS In an ongoing, adaptive platform randomized clinical trial, 721 critically ill and 58 non–critically ill hospitalized adults were randomized to receive an RAS inhibitor or control between March 16, 2021, and February 25, 2022, at 69 sites in 7 countries (final follow-up on June 1, 2022).
INTERVENTIONS Patients were randomized to receive open-label initiation of an ACE inhibitor (n = 257), ARB (n = 248), ARB in combination with DMX-200 (a chemokine receptor-2 inhibitor; n = 10), or no RAS inhibitor (control; n = 264) for up to 10 days.
MAIN OUTCOMES AND MEASURES The primary outcome was organ support–free days, a composite of hospital survival and days alive without cardiovascular or respiratory organ support through 21 days. The primary analysis was a bayesian cumulative logistic model. Odds ratios (ORs) greater than 1 represent improved outcomes.
RESULTS On February 25, 2022, enrollment was discontinued due to safety concerns. Among 679 critically ill patients with available primary outcome data, the median age was 56 years and 239 participants (35.2%) were women. Median (IQR) organ support–free days among critically ill patients was 10 (–1 to 16) in the ACE inhibitor group (n = 231), 8 (–1 to 17) in the ARB group (n = 217), and 12 (0 to 17) in the control group (n = 231) (median adjusted odds ratios of 0.77 [95% bayesian credible interval, 0.58-1.06] for improvement for ACE inhibitor and 0.76 [95% credible interval, 0.56-1.05] for ARB compared with control). The posterior probabilities that ACE inhibitors and ARBs worsened organ support–free days compared with control were 94.9% and 95.4%, respectively. Hospital survival occurred in 166 of 231 critically ill participants (71.9%) in the ACE inhibitor group, 152 of 217 (70.0%) in the ARB group, and 182 of 231 (78.8%) in the control group (posterior probabilities that ACE inhibitor and ARB worsened hospital survival compared with control were 95.3% and 98.1%, respectively).
CONCLUSIONS AND RELEVANCE In this trial, among critically ill adults with COVID-19, initiation of an ACE inhibitor or ARB did not improve, and likely worsened, clinical outcomes.

National Jewish Welfare Board, Army-Navy Division records, undated, 1917-1955, 1969, 1974
The collection consists mainly of minutes, surveys, reports, photographs and correspondence of both JWB personnel and U.S. military chaplains, directed toward or concerns with the Jewish men in the Armed Forces. The material covers such topics as arrangements for holidays (primarily the High Holy Days and Passover)--special food needs, services, furloughs, prayerbooks; budgeting and staffing; registration and marking of Jewish graves; anti-Semitism in the military; the general problems of Kashruth; communication between the men and their families; and general recreation and entertainment.27 boxes deal with the above topics as they relate to servicemen overseas, 8 boxes with servicemen in hospitals, and 7 boxes with veterans. Another 23 boxes deal specifically with the time (1941-1945) at which the JWB Army-Navy Division operated under the auspices of U.S.O.Also found in the collection are 2 boxes containing several speeches and miscellaneous files of Judge Irving Lehman, president of JWB, 1921-1940, and 18 boxes of Col. Harry Cutler, chairman of JWB, 1917-1921. 23 boxes contain the working papers for The JWB survey (New York; 1948) by Oscar I. Janowsky. 15 boxes contain various statistical compilations on Jewish communal organizations, and questionnaires with accompanying statistics based on surveys conducted by the JWB Statistics Dept. (1928-1943) on the services and personnel in Jewish community centers, nursery schools and summer camps.A detailed outline accompanies the collection.Donated by the National Jewish Welfare Board,Army-Navy Division is the branch of the JWB that intercedes for the needs and interests of Jewish military personnel; name officially introduced in 1941.Finding Aid available in Reading Room and on Internet.far0315digitized in par
