PURPOSE: To evaluate the suitability of MRI for lung cancer screening in a high-risk population. MATERIALS AND METHODS: A 5-year lung cancer screening program comparing MRI and low-dose CT (LDCT) in a high-risk population was initiated. 224 subjects were examined with MRI and LDCT. Acquired MRI sequences were T2w MultiVane XD, balanced steady-state-free precession, 3D T1w GRE, and DWI with a maximum in-room-time of 20 min. Categorization and management of nodules were based on Lung-RADS...

The side product of the cyclo-condensation reaction between ethyl benzimidazole-2-carboxyl-ate and the nitrile imine of the corresponding hydrazonyl chloride, C20H11BrClN5O, crystallized in two crystal forms. Form (1) is a co-crystal of the target compound (without any chlorine substituent) and a side product containing a Cl atom in position 2 of the bromo-phenyl group, C20H12BrN5O·0.143C20H11BrClN5O. (2) contains the pure side product. The slightly different conformation of the ring systems leads to a different packing of (1) and (2), but both crystal structures are dominated by π-π inter-actions...

Crohn's disease (CD) is a chronic inflammatory disease, in most patients involving the small and large bowel. In recent years, with the use of small bowel video capsule endoscopy (SBCE), it has become clear that in 50% or more of adults with established CD there is not only distal but also proximal small bowel involvement that suggests poor prognosis. A great deal of effort has been put into early diagnosis and stratification of patients into low versus high risk, thus directing treatment from step-up, or accelerated step-up, to top-down therapies...

BACKGROUND: The potential for simulation-based learning in neurosurgical training has led the Congress of Neurosurgical Surgeons to develop a series of simulation modules. The Northwestern Objective Microanastomosis Assessment Tool (NOMAT) was created as the corresponding assessment tool for the Congress of Neurosurgical Surgeons Microanastomosis Module. The face and construct validity of the NOMAT have been previously established. OBJECTIVE: To further validate the NOMAT by determining its interrater reliability (IRR) between raters of varying levels of microsurgical expertise...

Trauma is the leading cause of death worldwide for individuals under the age of 55. Interpatient genomic differences, in the form of candidate single nucleotide polymorphisms (SNPs), have been associated previously with adverse outcomes after trauma. However, the utility of these SNPs to predict outcomes based on a meaningful endpoint such as survival is as yet undefined. We hypothesized that specific SNP haplotypes could segregate trauma survivors from non-survivors. Genomic DNA samples were obtained from 453 blunt trauma patients, for whom complete daily clinical and biomarker data were available for 397...

PURPOSE: Radioactive seed localization (RSL) uses a titanium seed labeled with iodine-125 energy for surgery of nonpalpable breast lesions. RSL facilitates radiology-surgery scheduling and allows for improved oncoplasty compared with wire localization (WL). The purpose of this work was to compare the 2 techniques. METHODS: We performed a retrospective study of all breast lesions operated with RSL between February 2013 and March 2015 at our university institution, and compared with an equivalent number of surgeries performed with a single WL...

Ramy Younes, Paola Ponzo, Alfredo Marzano
Microangiopathic hemolytic anemia (MAHA) originates from a mechanical injury of red cells, caused by vascular thrombosis or stenosis. Cancer is a cause of MAHA as a consequence of both chemotherapy and disseminated disease itself. Here we describe the case of a 60-year-old man who developed a signet-ring cell carcinoma originated from the intrahepatic bile ducts, complicated by bone marrow metastasis and MAHA.

BACKGROUND: In asymptomatic end-stage renal disease (ESRD) patients undergoing vasodilator stress myocardial perfusion imaging (MPI) prior to renal transplantation (RT), the impact of pre-transplant heart rate response (HRR) to vasodilator stress on post-RT outcomes is unknown. METHODS: We analyzed a retrospective cohort of asymptomatic patients with ESRD who underwent a vasodilator stress SPECT-MPI and subsequently received RT. Blunted HRR was defined as HRR <28% for regadenoson stress and <20% for adenosine stress...

PROBLEM: In endocervical epithelial cells (End1/E6E7), miRNA let-7f plays an important role in the control of innate immunity. The underlying molecular mechanism for let-7f regulation in these cells remains largely unclear. METHODS OF STUDY: let-7f was knocked down in End1/E6E7 cells using siRNA, and differential gene expression was analyzed by microarray. Differentially expressed genes were validated by qPCR and Western blot. Expression of let-7f was studied by qPCR after inhibition of C/EBPβ with betulinic acid (BA) and pCMVβ plasmid and after overexpression of C/EBPβ with pCMVβ+ plasmid...

The central nervous system and the immune system, the two major players in homeostasis, operate in the ongoing bidirectional interaction. Stress is the third player that exerts strong effect on these two 'supersystems'; yet, its impact is studied much less. In this work employing carp model, we studied the influence of preliminary stress on neural and immune networks involved in post-injury brain regeneration. The relevant in-vivo models of air-exposure stress and precisely directed cerebellum injury have been developed...

BACKGROUND: Cerebral coenurosis is a disease of the central nervous system in sheep and goats, and is usually fatal unless surgical relief is provided. Information regarding neuroanaesthesia in veterinary medicine in goats is scant. CASE PRESENTATION: We describe anaesthetic management of an intact female goat (2 years; 16 kg) presented for craniectomy. The goat was sedated with xylazine (0.05 mg kg(-1), i.m.) and morphine (0.05 mg kg(-1), i.m.). General anaesthesia was induced 20 min later with propofol and maintained with a constant rate infusion of propofol (0...

BACKGROUND: Movement of the stent delivery system in the coronary bed as a result of the cardiac cycle is a well-known clinical observation that usually is either underestimated or ignored. This effect may potentially jeopardize precise stent deployment. We used a novel technology to objectively measure the relative intracoronary device motion in the different coronary segments throughout the cardiac cycle. METHODS: A total of 193 patients undergoing coronary angiography were enrolled and their studies were analyzed for device movement using the SyncVision System (Philips Volcano)...

BACKGROUND: Despite widespread use, evidence to support preemptive intraaortic balloon pump (IABP) insertion for patients undergoing high-risk coronary artery bypass graft (CABG) surgery remains sparse, and in need of a well-defined clinical trial. To inform the design of a prospective trial, we sought to review outcomes in randomized controlled trials (RCTs) of anticipatory IABP use vs control in patients undergoing high-risk CABG through meta-analysis. The primary endpoint was all-cause mortality within 30 days of surgery...

Granulomatosis with polyangiitis (GPA), previously known as Wegener's granulomatosis, is a pulmonary-renal syndrome affecting small and medium sized blood vessels. The disease has a prevalence in studies ranging from 3 to 15.7 cases per 100,000, with a noted increasing incidence and prevalence in more recent studies. Pulmonary manifestations include hemorrhage, lung cavitary lesions, and pulmonary fibrosis. Within the kidney, GPA is known to cause rapidly progressive pauci-immune crescentic glomerulonephritis...

The dual-mode interferometer (DMI) is an attractive alternative to Mach-Zehnder interferometers for sensor purposes, achieving sensitivities to refractive index changes close to state-of-the-art. Modern designs on silicon-on-insulator (SOI) platforms offer thermally stable and compact devices with insertion losses of less than 1 dB and high extinction ratios. Compact arrays of multiple DMIs in parallel are easy to fabricate due to the simple structure of the DMI. In this work, the principle of operation of an integrated DMI with differential outputs is presented which allows the unambiguous phase shift detection with a single wavelength measurement, rather than using a wavelength sweep and evaluating the optical output power spectrum...
