A rise and/or fall in high sensitivity cardiac troponin (hs-Tn) is critical in defining acute myocardial injury and therefore the diagnosis of acute myocardial infarction. A significant rise in hs-Tn is not well defined in current guidelines. Calculation of a z-score for two consecutive hs-Tn measurements is a method-independent measure of dynamic troponin elevation. However, the association of hs-Tn z-score with outcomes for unselected emergency department admissions is unknown. Moreover, the association of non-dynamic troponin elevations, as defined by a normal z-score, with clinical outcomes remains to be assessed.

We retrospectively calculated z-scores for patients presenting to emergency department over 18 months who had serial troponin measurements with at least one result >99th percentile using the Abbott hs-TnI assay. We assessed the association of z-score with discharge diagnosis, cardiac interventions, inpatient mortality, length of stay and readmission rates.

There were 2062 presentations for 1830 patients where a z-score was calculated. Z-score was elevated in 1080 presentations. Dynamic troponin elevation (z-score ≥ 2) was associated with acute myocardial infarction (OR = 9.1,
 < 0.01), admission to an inpatient unit (95 vs. 88%,
 < 0.01), increased inpatient length of stay (97 vs. 65 days,
 < 0.01), inpatient coronary intervention (21 vs. 6%,
 < 0.01) and mortality (4.4 vs. 2.4%,
 < 0.05) compared with myocardial injury with a static troponin elevation.

Z-score is an assay-independent tool to alert clinicians of significant, dynamic troponin elevation and acute myocardial injury. It is associated with poorer clinical outcomes.

Intestinal endometriosis is believed to affect about one-third of patients with endometriosis4; 72-95% of patients experience recto-sigmoid involvement.2,3 Occasionally, endometriotic lesions precipitate mass effect or infiltrate the bowel wall, mimicking a neoplasm. In the index case, we evaluated a G0P0 41-year-old perimenopausal female with near obstructing sigmoid endometrioma, clinically presented, investigated, and managed in the lines of sigmoid colon carcinoma. Computed Tomography revealed marked distention of the distal descending and proximal sigmoid colon to the level of a [possible] intraluminal mass. CA-125 was 247.4. Transvaginal ultrasound revealed a heterogeneous irregularity adjacent the left adnexa. Flexible sigmoidoscopy to 12-15 cm was unable to pass liquid or visualize the lumen secondary to extrinsic colonic obstruction. She underwent exploratory laparotomy with sigmoidectomy, oversew of rectal stump, and descending colostomy. Left fallopian tube and ovary were adherent to sigmoid mass, therefore, removed en-bloc. Histopathological report revealed extensive endometriosis involving the muscularis propria and serosal surface of colon and ovary, with fibrinous serosal adhesions of the sigmoid colon. While inconsistent clinical presentation, similar radiographic features, and colonoscopy with other inflammatory or malignant lesions of the bowel makes the preoperative diagnosis challenging, colonic endometriosis is to always be considered as one of the differential diagnoses in reproductive age women with patterned, cyclic gastrointestinal symptoms, and intestinal masses of uncertain etiology or diagnosis.[Figure see text].Background COVID-19 may present with a variety of cardiovascular manifestations, and elevations of biomarkers reflecting myocardial injury and stress are prevalent. SARS-CoV-2 has been found in cardiac tissue, and myocardial dysfunction post-COVID-19 may occur. However, the association between SARS-CoV-2 RNA in plasma and cardiovascular biomarkers remains unknown. Methods and Results COVID MECH (COVID-19 Mechanisms) was a prospective, observational study enrolling consecutive, hospitalized patients with laboratory-confirmed infection with SARS-CoV-2 and symptoms of COVID-19. Biobank plasma samples used to measure SARS-CoV-2 RNA and cardiovascular and inflammatory biomarkers were collected in 123 patients at baseline, and in 96 patients (78%) at day 3. Patients were aged 60±15 (mean ± SD) years, 71 (58%) were men, 68 (55%) were White, and 31 (25%) received mechanical ventilation during hospitalization. SARS-CoV-2 RNA was detected in plasma from 48 (39%) patients at baseline. Patients with viremia were more frequently men, had more diabetes mellitus, and lower oxygen saturation. Patients with viremia had higher concentrations of interleukin-6, C-reactive protein, procalcitonin, and ferritin (all less then 0.001), but comparable levels of cTnT (cardiac troponin T; P=0.09), NT-proBNP (N-terminal pro-B-type natriuretic peptide; P=0.27) and D-dimer (P=0.67) to patients without viremia. SARS-CoV-2 RNA was present in plasma at either baseline or day 3 in 50 (52%) patients, and these patients experienced increase from baseline to day 3 in NT-proBNP and D-dimer concentrations, while there was no change in cTnT. Conclusions SARS-CoV-2 viremia was associated with increased concentrations of inflammatory, but not cardiovascular biomarkers. WH-4-023 supplier NT-proBNP and D-dimer, but not cTnT, increased from baseline to day 3 in patients with viremia. Registration URL https//www.clinicaltrials.gov; Unique identifier NCT04314232.Background Black Americans have a higher risk of hypertension compared with White Americans. Perceived discrimination is a plausible explanation for these health disparities. Few studies have examined the impact of perceived discrimination on the incidence of hypertension among a racially diverse sample. Our study examined associations of everyday and lifetime discrimination with incidence of hypertension and whether these associations varied by sex, discrimination attribution, and racial residential segregation. Methods and Results The study included 3297 Black, Hispanic, Chinese, and White participants aged 45 to 84 years from the Multi-Ethnic Study of Atherosclerosis who were without hypertension at exam 1 (2000-2002) and who completed at least 1 of 5 follow-up exams (2002-2018). Cox proportional hazards regression was used to estimate associations of perceived discrimination with incident hypertension. Over the follow-up period, 49% (n=1625) of participants developed hypertension. After adjustment for age, sex, socioeconomic status, hypertension risk factors, and study site, Black participants reporting any lifetime discrimination (compared with none) were more likely to develop hypertension (hazard ratio [HR], 1.
