Lower Urinary Tract Symptoms in a prospective cohort of COVID-19 survivors.

Purpose: To analyze the prevalence of lower urinary tract symptoms (LUTS) in patients who survived moderate and severe forms of COVID-19 and the risk factors for LUTS six months after hospitalization.

Materials And Methods: In this prospective cohort study, patients were evaluated six months after hospitalization due to COVID-19. LUTS were assessed using the International Prostate Symptom Score.

Widespread micronodular hepatic metastases of neuroendocrine tumor detected by [Ga]DOTATATE PET/CT.

Neuroendocrine tumors (NET) encompass a diverse, heterogeneous group of neoplasms that originate from the secretory cells of the neuroendocrine system. These neoplasms typically express the somatostatin receptor (SSTR), which can be targeted by molecular agents for imaging and therapy. This is particularly advantageous for imaging NETs that are indolent, slow-growing, and less well detected by [F]FDG and for the detection of occult disease not easily identified by anatomic imaging.

Dose-dependent effects of ultrasound therapy on hepatocellular carcinoma.

Non-invasive ischemic cancer therapy requires reduced blood flow whereas drug delivery and radiation therapy require increased tumor perfusion for a better response. In this study we investigate the hypothesis that different dose models of antivascular ultrasound therapy (AVUS) can have opposite effects on hepatocellular carcinoma (HCC) tumor blood flow. HCC was induced in 22 Wistar rats by ingestion of diethylnitrosamine (DEN) for 12 weeks.

Microbubble-enhanced ultrasound for the antivascular treatment and monitoring of hepatocellular carcinoma.

: Hepatocellular carcinoma (HCC) is the most common primary liver malignancy, and its current management relies heavily on locoregional therapy for curative therapy, bridge to transplant, and palliative therapy. Locoregional therapies include ablation and hepatic artery therapies such as embolization and radioembolization. In this study we evaluate the feasibility of using novel antivascular ultrasound (AVUS) as a noninvasive locoregional therapy to reduce perfusion in HCC lesions in a rat model and, monitor the effect with contrast-enhanced ultrasound imaging.

B-mode ultrasound for the assessment of hepatic fibrosis: a quantitative multiparametric analysis for a radiomics approach.

Hepatic fibrosis and cirrhosis are a growing global health problem with increasing mortality rates. Early diagnosis and staging of hepatic fibrosis represent a major challenge. Currently liver biopsy is the gold standard for fibrosis assessment; however, biopsy requires an invasive procedure and is prone to sampling error and reader variability.

Predictive Value of Abnormal Findings on Covered Transjugular Intrahepatic Portosystemic Shunt Baseline Doppler Sonography.

Doppler ultrasound (DUS) is frequently performed as a screening and diagnostic modality to evaluate the transjugular intrahepatic portosystemic shunt (TIPS) for short- and intermediate-term complications of the procedure. However, the clinical significance of initial frequently observed abnormalities in flow velocities, gradient, and direction in patients with covered TIPS is less studied. A retrospective study was performed between January 2005 and December 2014, and all patients undergoing covered TIPS procedure for the management of portal hypertension were included.

Incidence, determinants and outcomes of pregnancy-associated hepatitis B flares: A regional hospital-based cohort study.

Background & Aims: There is limited knowledge about hepatitis B virus (HBV) flare among pregnant women. We evaluated the incidence, determinants and outcomes of HBV flare in a multicultural cohort of pregnant HBV-infected women in the United States.

Methods: We performed a retrospective cohort study of pregnant hepatitis B surface antigen-positive women cared for at hospital-based clinics of 4 medical centres in Southeastern Pennsylvania from 2006 to 2015.

Detection of Helicobacter pylori resistance to clarithromycin and fluoroquinolones in Brazil: A national survey.

Aim: To evaluate bacterial resistance to clarithromycin and fluoroquinolones in Brazil using molecular methods.

Methods: The primary antibiotic resistance rates of Helicobacter pylori (H. pylori) were determined from November 2012 to March 2015 in the Southern, South-Eastern, Northern, North-Eastern, and Central-Western regions of Brazil.

Mucinous Bladder Adenocarcinoma: Case Report and Literature Review.

Primary mucinous adenocarcinoma is an extremely rare type of bladder cancer, with aggressive behavior and poor response to chemotherapy and radiotherapy. The symptoms are similar to those of other bladder tumors. Surgery is the main treatment and remains the only curative option.
