Carbohydrate antigen 19-9 (CA 19-9) is widely recognized as a tumor marker primarily associated with pancreatic cancer. However, its elevation in benign pancreaticobiliary conditions complicates its diagnostic utility. We present the case of a 39-year-old male with no significant medical history who presented with symptoms of abdominal pain, nausea, vomiting, and diarrhea.

Introduction: We assessed the clinical-epidemiological profile of acquired immune deficiency syndrome (AIDS) patients in the Santos region (São Paulo state) with the highest AIDS prevalence in Brazil.
Methods: Information was extracted from records of 409 AIDS-infected patients hospitalized between 2011 and 2016.
Results: Human immunodeficiency virus (HIV) was diagnosed in 24.
Background: Experimental studies suggest that mechanical cell washing to remove pro-inflammatory components that accumulate in the supernatant of stored donor red blood cells (RBCs) might reduce inflammation and organ injury in transfused patients.
Methods: Cardiac surgery patients at increased risk of large-volume RBC transfusion were eligible. Participants were randomized to receive either mechanically washed allogenic RBCs or standard care RBCs.
Introduction: It has been suggested that removal of proinflammatory substances that accumulate in stored donor red cells by mechanical cell washing may attenuate inflammation and organ injury in transfused cardiac surgery patients. This trial will test the hypotheses that the severity of the postoperative inflammatory response will be less and postoperative recovery faster if patients undergoing cardiac surgery receive washed red cells compared with standard care (unwashed red cells).
Methods And Analysis: Adult (≥16 years) cardiac surgery patients identified at being at increased risk for receiving large volume red cell transfusions at 1 of 3 UK cardiac centres will be randomly allocated in a 1:1 ratio to either red cell washing or standard care.
Objectives: Based on previous evidence showing that early weaning disturbs the ontogenesis of rat gastric glands, which are the major site of ghrelin synthesis, we investigated the distribution of ghrelin and its receptor (GHS-R) in the rat gastric epithelium during postnatal development and evaluated the effects of early weaning on their levels. Additionally, we studied the contribution of ghrelin to gastric growth during the abrupt nutrient transition.
Methods: Wistar rats were submitted to early weaning at 15 d and suckling counterparts were taken as controls.
Telcagepant is a calcitonin gene-related peptide (CGRP) receptor antagonist being evaluated for acute migraine treatment. CGRP is a potent vasodilator that is elevated after myocardial infarction, and it delays ischemia during treadmill exercise. We tested the hypothesis that CGRP receptor antagonism does not reduce treadmill exercise time (TET).

The blood pressure (BP) effects of naproxcinod and naproxen were assessed in an 8-week, double-blind, crossover study in 131 hypertensive patients aged 50 to 74 years. Patients received naproxcinod 750 mg twice daily or naproxen 500 mg twice daily, then the alternate treatment, each for 14 days, with placebo run-in/washout before each active treatment period and 24-hour ambulatory BP monitoring conducted before and after each active treatment period. Mean change from baseline in average 24-hour systolic BP (SBP) after 2 weeks of treatment numerically favored naproxcinod 750 mg twice daily (least-squares [LS] mean for naproxcinod minus naproxen: -1.

Background: Several small, non-placebo-controlled trials suggest that fasudil reduces myocardial ischemia in patients with stable or vasospastic angina.
Methods: In a multicenter, double-blind, placebo-controlled, randomized trial, the efficacy and safety of fasudil were evaluated in stable angina patients.
The efficacy and safety of nisoldipine-extended release (ER) and amlodipine were compared in a 6-week multicenter, randomized, double-blind, double-dummy, parallel group, titration-to-effect trial in patients with stage 1 to 2 systemic hypertension (90 to 109 mm Hg diastolic blood pressure [BP]) and chronic stable angina pectoris. After a 3-week placebo run-in period, patients (n = 120) were randomly assigned to active treatment with either nisoldipine-ER (20 to 40 mg) or amlodipine (5 to 10 mg) once daily, titrated as necessary after 2 weeks to achieve diastolic BP <90 mm Hg. After 6 weeks, the mean reduction in systolic/diastolic BP from baseline was 15/13 mm Hg with nisoldipine-ER and 13/11 mm Hg with amlodipine (p = NS/p = NS).

Background: Erectile dysfunction (ED) is common among men with CAD. PDE5 inhibition is increasingly the preferred treatment option for ED.
Background: Mibefradil, a newly approved antihypertensive and antianginal drug, is the first member of a new class of calcium antagonists (CAs), the tetralol derivatives, that selectively blocks T-type Ca2+ channels in contrast to classical CAs which, at therapeutic concentrations, block only L-type Ca2+ channels. Since patients with chronic stable angina pectoris typically may be treated with the combination of a long-acting nitrate and a CA, the additive efficacy and safety of mibefradil in combination with nitrate therapy needs to be determined.
Hypothesis: This study was designed to assess the efficacy, tolerability, and safety of mibefradil when added to long-acting nitrate therapy in patients with chronic stable angina pectoris.
This multicenter, double-masked, randomized, forced-titration, parallel-group trial was designed to determine whether we could confirm the results of a previous trial that demonstrated a significantly greater antihypertensive effect for mibefradil compared with diltiazem CD. Two hundred thirty-nine patients with uncomplicated mild-to-moderate essential hypertension and a baseline sitting diastolic blood pressure (SDBP) between 95 and 114 mm Hg were randomized to receive once-daily treatment with mibefradil 50 mg (n = 119) or diltiazem CD 180 mg (n = 120). After 4 weeks of treatment, all patients underwent forced titration to mibefradil 100 mg or diltiazem CD 360 mg for an additional 8 weeks.

Methods: Medical records of 171 consecutive patients with atrial fibrillation and acute stroke at six U.S.
Background: The risk of stroke in patients with atrial fibrillation can be significantly reduced with antithrombotic therapy. Despite this, many physicians remain hesitant to prescribe warfarin sodium or aspirin therapy for patients with atrial fibrillation.
Objective: To assess the use of antithrombotic therapy in patients with atrial fibrillation at 6 academic hospitals in the United States.
Optimal drug therapy for patients with acute myocardial infarction (AMI) is well described in the medical literature. However, data on the actual pharmacologic management of patients surviving AMI at academic hospitals is unavailable. The purpose of this study was to document treatment profiles in 500 patients surviving AMI at 12 academic hospitals in the United States.

Mild-to-moderate essential hypertension is a major risk factor for stroke and cardiovascular mortality and morbidity. Morbidity can be reduced significantly by lowering high blood pressure, and with the effective antihypertensive drugs now available, it is ever more important to identify and treat the estimated 50 to 60 million hypertensive persons in the United States. Yet a high percentage of persons being treated stop taking their medication and refuse to comply with their therapeutic regimen.
