The association between vitamin D levels and nonalcoholic fatty liver disease (NAFLD) has been recognized. However, few studies showed independent associations between vitamin D deficiency and NAFLD after a sex-related adjustment for metabolic factors. We aimed to study whether vitamin D deficiency is an independent risk factor of NAFLD even after controlling for metabolic syndrome and visceral fat in both sexes. In this cross-sectional study, 7,514 Korean adults (5,278 men, 2,236 women) participated in a health check-up program...

REVIEW
Ashley Altman, Steven M Zangan
Differentiating benign and malignant biliary strictures is a challenging and important clinical scenario. The typical presentation is indolent and involves elevation of liver enzymes, constitutional symptoms, and obstructive jaundice with or without superimposed or recurrent cholangitis. While overall the most common causes of biliary strictures are malignant, including cholangiocarcinoma and pancreatic adenocarcinoma, benign strictures encompass a wide spectrum of etiologies including iatrogenic, autoimmune, infectious, inflammatory, and congenital...

REVIEW
Stephen Thomas, Kayleen Jahangir
Clinical data such as history, physical examination, and laboratory tests are useful in identifying patients with biliary obstruction and biliary sources of infection. However, if intervention is planned, noninvasive imaging is needed to confirm the presence, location, and extent of the disease process. Currently, the most commonly available and used noninvasive modalities are ultrasound (US), computed tomography (CT), magnetic resonance (MR), and nuclear medicine hepatobiliary scintigraphy (HIDA). US is quick, portable, readily available, and is commonly the first imaging modality used when biliary pathology is suspected...

OBJECTIVES: We propose the application of virtual nodules to evaluate the performance of computer-aided detection (CAD) of lung nodules in cancer screening using low-dose computed tomography (CT). METHODS: The virtual nodules were generated based on the spatial resolution measured for a CT system used in an institution providing cancer screening and were fused into clinical lung images obtained at that institution, allowing site-specificity. First, we validated the virtual nodules as an alternative to artificial nodules inserted into a phantom...

BACKGROUND: Positional compression of the vertebral artery (VA) due to cervical spondylosis is an uncommon cause of stroke. We report two cases of cervical spondylosis causing wake-up stroke, which is extremely rare. CASE DESCRIPTION: The first case was a 78-year-old woman who presented with vertigo and vomiting lasting from waking up. Magnetic resonance (MR) images and angiography documented right cerebellar infarction, and stenosis of the right cervical VA. Dynamic angiography revealed that the right VA was occluded when her neck was extended or rotated to the right...

Lung cancer is a devastating disease, the deadliest form of cancer in the world and in the United States. As a consequence of CMS's determination to provide low-dose CT (LDCT) as a covered service for at-risk smokers, LDCT lung cancer screening is now a covered service for many at-risk patients that first requires counseling and shared clinical decision making, including discussions of the risks and benefits of LDCT screening. However, shared decision making fundamentally relies on the premise that with better information, patients will arrive at rational decisions that align with their preferences and values...

The objective of our study was to examine the anti-tumor effect of paclitaxel (PTX)-loaded polymeric nanoparticles (PTX-NPs) combined with circadian chronomodulated chemotherapy. Our intention was to screen out the best time of the day for the drug to be administered. PTX-NPs with a diameter of approximately 168nm were prepared through a thin film dispersion technique. The PTX in PTX-NPs showed an initial fast release subsequently a slower and sustained release. The cytotoxicity of chronomodulated administration of PTX-NPs in vitro confirmed that its cytotoxic effect was lower than that of PTX injection, and showed a time-dependent effect...

Fares Benmiloud, Michel Grino, Charles Oliver, Anne Denizot
PURPOSE: Since intrathoracic goiters (IG), either cervico-mediastinal goiters (CMGs) or mediastinal nodules (MNs), can lead to sternotomies and/or evitable reoperations, their detection is mandatory before thyroid surgery. A systematic screening by CT scan or MRI is not conceivable because of their expensiveness. We tested if conventional chest radiography (CCR) could remain a good screening tool for IG before thyroid surgery. METHODS: In this retrospective study (2554 patients), CCR usefulness was evaluated in relation with patients' complaints, clinical examination, neck US, and anatomical and surgical findings...

We describe a patient with an incidental finding of a large mass adjacent to the heart detected on a screening CT scan. The differential diagnosis included primary and secondary tumours of the heart. Subsequent investigation with trans-thoracic echocardiogram and cardiac MRI confirmed a diagnosis of a giant pericardial lipoma, one of the common benign primary cardiac tumours.

The type VI secretion system (T6SS) of bacteria plays a key role in competing for specific niches by the contact-dependent killing of competitors. Recently, Rhs proteins with polymorphic C-terminal toxin-domains that inhibit or kill neighboring cells were identified. In this report, we identified a novel Rhs with an MPTase4 (Metallopeptidase-4) domain (designated as Rhs-CT1) that showed an antibacterial effect via T6SS in Escherichia coli. We managed to develop a specific strategy by matching the diagnostic domain-architecture of Rhs-CT1 (Rhs with an N-terminal PAAR-motif and a C-terminal toxin domain) for effector retrieval and discovered a series of Rhs-CTs in E...
