Abstract
Abstract
Background
In an effort to improve outcomes of STEMI patients, we developed a secure mobile application (app) to streamline real-time communication and coordination between multiple teams taking care of STEMI patients in a large health care system. The app includes multi-level alarm and notification systems, instant EKG transmission for quick interpretation, activation of the cardiac catheterization laboratory (CCL) after expert case review, secure video chat among team members facilitating clinical discussion, continuous updates on patients' clinical status and ambulance location tracking.
Purpose
One of the major shortcomings in STEMI system of care has been long delays in transfer of patients from non-PCI capable hospitals to a receiving center for primary PCI. To address the challenges of interhospital transfer, we designed a pilot project employing the app for STEMI transfer from a first contact hospital to our CCL. This report assesses the effect of the app on door-to-device time by comparing the key metric for STEMI transfer before (historic) and after app launch.
Methods
The pilot project involved key leadership stakeholders from Emergency Medicine and Nursing Departments at the referring hospital, CCL and our transfer center. During pilot period (July 2021 to January 2022) the referring center activated STEMI alarms using app activation in parallel with the previously established STEMI activation process via traditional phone calls to the transfer center. The built-in workflow redundancy was introduced to ensure the rapid and efficient, and at the same time, safe and reliable response to STEMI alert. In preparation for the pilot, more than 250 people were provisioned accounts, trained on their user-specific roles and scheduled in the app according to their schedules.
Results
A total of 40 suspected STEMIs were activated through the app during the pilot study; among them 30 cases were accepted for transfer and 10 rejected. After excluding patients who expired during transfer, were intubated, or had normal coronaries, final study population included 13 STEMI cases activated through the app. These cases were compared with 43 STEMIs activated through the traditional pathway from January 2019 to July 2021 before app launch. After implementing the app, the mean door-to-device time for STEMI transfer decreased from 120.3±48.3 to 91.8±15.4 min (P=0.002) (Figure 1). The significant improvement, 29 min (24%), of the key metric for interhospital transfer resulted in all STEMI cases meeting AHA goal of door-to-device time ≤120 minutes after the app launch. The respective percent of STEMI cases meeting the goal before app was 71% (Figure 2).
Conclusions
Implementation of a mobile app into STEMI workflow of a large urban healthcare system had a significant impact on the quality of care for transfer of STEMI patients, which has also helped bring our clinical practice closer to the AHA guidelines pertaining to the first door-to-device time.

Abstract
BACKGROUND Many commonly ingested substances such as grapefruit juice and Hypericum perforatum (St John's wort) have been found to interact with important therapeutic agents such as cyclosporine (INN, ciclosporin). The mechanism for these interactions is thought to involve modulation of the activity of the drug-metabolizing enzyme cytochrome P4503A4 (CYP3A4) and/or the drug transport protein Pglycoprotein. In vitro data suggest that red wine may interact with CYP3A4 substrates such as cyclosporine. METHODS We conducted a randomized, 2-way crossover study of 12 healthy individuals. Subjects received a single 8-mg/kg dose of oral cyclosporine with water (control) and with 12 oz of red wine (Blackstone Merlot, 1996; Blackstone Winery, Graton, Calif). Whole blood was analyzed for cyclosporine and 6 metabolites by specific fluorescence polarization immunoassay and tandem liquid chromatography-mass spectrometry. Blood levels of cyclosporine were compared between the 2 arms. RESULTS Red wine caused a 50% increase in the oral clearance of cyclosporine. Systemic exposure as measured by the area under the concentration-versus-time curve (AUC) and peak concentration (C(max)) were significantly decreased by red wine. However, half-life was not affected, suggesting that red wine decreased cyclosporine absorption. In vitro, the solubility of cyclosporine in red wine appeared to be lower than in water. CONCLUSIONS Administration of cyclosporine with red wine causes a significant decrease in cyclosporine exposure. Because cyclosporine is a narrow therapeutic range compound, caution may be warranted with concomitant intake of red wine and cyclosporine.

Abstract
CONCLUSIONS Urinary TAP obtained within the first 48 h of the onset of symptoms can distinguish patients with severe acute pancreatitis. BACKGROUND Urinary trypsinogen activation peptide (TAP) has recently been described as an early marker of severity in acute pancreatitis. METHODS In a multicenter study, urine samples were collected for TAP concentration at 6-12, 24, and 48 h after admission from 139 patients with acute pancreatitis (99 with mild disease, 40 with severe disease) and from 50 control patients. Severity of acute pancreatitis was defined by the presence of organ failure and/ or pancreatic necrosis on dynamic contrast-enhanced computed tomography. RESULTS Median urinary TAP in the 139 patients with acute pancreatitis compared to the 50 control patients was significantly higher at admission, 4.6 vs 0.8 ng/mL (p < 0.001), and 6-12 h, 1.9 vs 0.55 ng/mL (p = 0.04). Among patients who presented within 48 h of the onset of symptoms, the median urinary TAP for severe pancreatitis (9 patients) compared to mild pancreatitis (40 patients) was significantly higher at admission, 29.6 vs. 3.6 ng/mL (p = 0.001). Also, when obtained within 48 h of the onset of symptoms, all patients with severe pancreatitis had an admission urinary TAP level > 10 ng/mL. The sensitivity and specificity of an admission urinary TAP > or = 10 for severe pancreatitis was 100 and 85%, respectively. Given a cutoff of 10 ng/mL for an admission urinary TAP obtained within 48 h of the onset of symptoms, the negative predictive value was 100% for mild pancreatitis.

Abstract
Pancreatic cysts include pseudocysts, serous tumors, and mucinous tumors, some of which are malignant. The clinical and radiologic features of these lesions may not permit a preoperative diagnosis. Analysis of percutaneous cyst fluid aspirates for cytologic findings, tumor markers, enzymes, and viscosity has been proposed as an aid to differential diagnosis. The combination of cytologic findings, carcinoembryonic antigen level, and viscosity will usually differentiate mucinous from nonmucinous cysts, whereas cytologic findings and levels of tumor markers CA 15-3 and CA 72-4 are useful to predict malignancy. Pseudocysts can be identified by a combination of cytologic features; levels of tumor markers, including NB/70K; and levels of enzymes, including amylase isoenzymes and leukocyte esterase. Serous tumors are a diagnosis of exclusion, although in 50% of cases the cytologic findings will indicate a serous tumor. When compared with conventional methods of differentiating pancreatic cysts, cyst fluid analysis is a promising new approach to the evaluation of these diagnostically difficult lesions.

Abstract
Cystic islet-cell tumors are rare neoplasms that may be confused with more familiar cystic pancreatic lesions, such as pseudocysts, serous cystadenoma, and mucinous tumors. Analysis of aspirated cyst fluid for tumor markers (carcinoembryonic antigen [CEA], CA-125, and CA-15.3), enzymes (amylase and lipase), viscosity, and cytology has been proposed as an aid to preoperative differential diagnosis. These tests will distinguish mucinous from nonmucinous cysts and usually help in determining malignancy. However, cyst fluid parameters from rarer types of pancreatic cystic tumors have not been described. We report the clinical and pathologic features of two cystic islet-cell tumors including cyst fluid parameters in one of the cases. Two cases of cystic islet-cell tumors were identified by clinical history, histopathologic, and immunohistochemical techniques. Cyst fluid was aspirated intraoperatively from one case and analyzed for CEA, CA-125, CA 15.3, insulin, amylase, viscosity, and cytology. Cyst fluid analysis showed low values for CEA, CA-125, and CA-15.3, low viscosity, and variable amylase content. This spectrum of findings is similar to that of serous cystadenomas. Cyst fluid cytologic examination was positive for neuroendocrine-type epithelial cells and insulin levels were elevated, observations indicative of an islet-cell tumor. Analysis of fluid from cystic islet-cell tumors may aid in the preoperative differentiation of these tumors from more common pancreatic cystic lesions. These findings represent the first report of the characteristics of the fluid in these uncommon tumors.

Abstract
The term "microcystic adenoma" of the pancreas has gained nearly universal acceptance among pathologists owing to the characteristic gross and microscopic features of this tumor. The possible existence of macrocystic variants of serous cystadenoma has been largely ignored in the literature. We report five cases of macrocystic serous cystadenoma of the pancreas, two of which were of the unilocular type. These tumors exhibited distinctly different macroscopic features from microcystic adenoma, which created diagnostic difficulties for both the radiologist and pathologist. Computed tomography scans on all five cases were thought to represent either mucinous cystic neoplasms or pseudocysts and the tumors were misclassified in two of three cases on which intraoperative frozen sections were performed. In our opinion, microcystic and macrocystic serous tumors represent morphologic variants of the same benign pancreatic neoplasm and we suggest that the term "serous cystadenoma" be used to encompass all variants of this benign neoplasm.
