Pre-exposure prophylaxis (PrEP) for HIV is underutilized, particularly among attendees of obstetrics and gynecology (Ob/Gyn) clinics. Lack of self-perception of HIV risk is a barrier to PrEP utilization, and a lack of understanding of community risk factors for HIV may contribute to that lack of self-perception of risk. Attendees of general Ob/Gyn clinics in New Orleans completed a survey assessing HIV knowledge, self-perception of HIV risk, and interest in PrEP.

Often composed of volunteers from a variety of backgrounds, professional societies can guide the cultural norms and expectations of an industry by acting as critical leaders for supporting diversity, equity, and inclusion initiatives. The present manuscript explains how professional societies, like the Organization of Biological Field Stations (OBFS), can embrace transdisciplinary approaches to create more inclusive (in)tangible spaces to address serious problems facing industries today.

Aims: We examined the accuracy of MRI in detecting PCA, and in identifying extracapsular extension (ECE) and seminal vesicle invasion (SVI) in PCA patients at our institution.
Methods: We retrospectively reviewed pre-biopsy MRI findings and correlated the same with subsequent radical prostatectomy pathology reports in all patients undergoing radical prostatectomy between 2010 and 2012.
Objective: The purpose of this study was to investigate the role of positron emission tomography (PET) with 18F-fluorodeoxyglucose (FDG) in differentiating benign from malignant disease in patients with possible pancreatic malignancy.
Subjects And Methods: All patients with a possible diagnosis of pancreatic carcinoma based on CT or ERCP findings were eligible for inclusion in this prospective study. PET imaging of the abdomen was performed in 37 patients and was interpreted as positive if FDG activity in the pancreas exceeded background activity and as negative if activity was less than or equal to background activity.
Purpose: To evaluate triple-phase helical computed tomography (CT) of carcinoid liver metastases.
Materials And Methods: Triple-phase helical CT was performed in 31 patients with proved carcinoid liver metastases. Hepatic arterial-dominant phase (HAP) and portal venous-dominant phase (PVP) images were obtained 20 and 70 seconds after intravenous iopamidol injection.
Objective: The purpose of this study was to determine the optimal time for obtaining delayed images with contrast-enhanced CT in patients who have intrahepatic or hilar cholangiocarcinoma.
Subjects And Methods: CT studies were performed in 25 consecutive patients with proven cholangiocarcinoma, including six patients who had undergone radiotherapy or chemotherapy. Dynamic images of the liver were obtained after 150 ml of IV contrast material was administered at 3 ml/sec.
Purpose: To determine the relative value of hepatic arterial and portal venous phase helical computed tomographic (CT) scans for tumor detection and vascular opacification in patients with pancreatic malignancy.
Materials And Methods: Ninety-five patients who had or were suspected of having pancreatic disease underwent dual-phase helical CT. Arterial phase scans were acquired 20-40 seconds after contrast material administration; venous phase scans, 70-100 seconds after administration.
Objective: Our purpose was to identify clinical or radiologic features predictive of response to percutaneous cholecystostomy performed for the treatment of acute cholecystitis.
Materials And Methods: The clinical records and radiologic images of patients who underwent percutaneous cholecystostomy for suspected acute cholecystitis between January 1987 and July 1994 were retrospectively reviewed. A response to percutaneous cholecystostomy was defined as an improvement in clinical symptoms and signs or reduction in fever and WBC to normal within 72 hr of percutaneous cholecystostomy.
Background: Positron emission tomography (PET) with F-18 fluorodeoxyglucose (FDG) is a useful technique for detection of malignancy. The purpose of this study was to determine if FDG-PET scanning using visual and quantitative analyses can identify patients with recurrent colorectal tumor following abdominoperineal resection.
Methods: Eighteen patients were evaluated for possible local recurrence of rectal carcinoma following abdominoperineal resection.
Purpose: To investigate the effect of arterial injection site and splenic volume on the hepatic zebra pattern seen at computed tomographic (CT) arterial portography.
Materials And Methods: Images from CT arterial portographic examinations, performed via either the splenic artery (SA)(n = 47) or superior mesenteric artery (SMA)(n = 51) in 98 patients, were reviewed. The hepatic parenchymal enhancement pattern was assessed by three blinded reviewers.
Purpose: To determine whether the diagnostic quality of computed tomography (CT) during arterial portography (CTAP) performed via the splenic artery (SA) is better than that performed via the superior mesenteric artery (SMA).
Materials And Methods: The authors evaluated CTAP images obtained in 98 patients from 1991 to 1994; 47 examinations were performed via the SA and 51 were performed via the SMA. Images were reviewed, by consensus, by three radiologists blinded to catheter location.
Objective: The purpose of this study was to review the radiologic manifestations of the hepatopulmonary syndrome.
Materials And Methods: We retrospectively reviewed clinical records, chest radiographs, 99m Tc-macroaggregated albumin (MAA) perfusion lung scans, chest CT scans, and pulmonary angiograms of 10 patients with proven hepatopulmonary syndrome.
Results: Chest radiographs showed basilar, medium-sized (1.
Malignant melanoma, a common malignancy whose prevalence is increasing, represents 1-3% of cancers in the United States [1]. At autopsy, metastatic deposits to the gut are frequently found, but less than 9% of melanoma patients are diagnosed with gastrointestinal metastases while living [2]. Modern management includes aggressive surgical therapy to prolong survival and to palliate the disease [3].

Patients And Methods: In a prospective, uncontrolled clinical trial, pulmonary artery pressures (systolic, diastolic, mean) of 116 patients referred for pulmonary angiography were recorded before and 1 and 5 minutes after injection of contrast material.
Results: There was a statistically significant rise in systolic, diastolic, and mean pulmonary artery pressure at 1 minute (4.
Purpose: To determine the success and safety of percutaneous transhepatic liver biopsy with tract embolization (PBTE) in patients at risk for standard transhepatic biopsy.
Materials And Methods: Eighty biopsies were performed in 76 patients with diffuse liver disease: 57 biopsies in patients with coagulopathy (11 of whom also had ascites), 16 in patients with mild coagulopathy and ascites, and seven in patients with ascites only. Biopsy was performed with a cutting needle placed through a 10-cm vascular sheath.
Objective: To determine the sensitivity of MR imaging for the detection of abnormal parathyroid glands in patients with biochemical evidence of hyperparathyroidism and to identify the factors affecting detection.
Subjects And Methods: Between 1985, 82 patients with biochemical proof of hyperparathyroidism were referred for MR imaging of the parathyroid glands prior to surgery. Axial T1- (600/20 [TR/TE]) and T2-weighted (2500/40, 80) spin-echo images were obtained using an anterior neck surface coil.
Purpose: To evaluate the safety of pulmonary angiography performed with iopamidol compared with pulmonary angiography performed with ionic contrast media.
Materials And Methods: The data in 1,434 patients who underwent pulmonary angiography with iopamidol 76% were retrospectively reviewed. Complications that occurred within 48 hours were identified with review of hospital charts and/or computer records.
