OBJECTIVE: Endovascular aneurysm repair (EVAR) can be performed through percutaneous or surgical access. Our goal was to assess the difference in perioperative outcomes based on access type in a real-world setting. METHODS: The Vascular Quality Initiative (VQI) database was queried for EVAR. Univariable analysis and multivariable analysis were used to determine the independent effect of access type. RESULTS: There were 8340 (64%) and 4747 (36%) EVAR procedures performed through percutaneous and surgical access (3395 [72%] transverse and 1352 [28%] vertical incisions)...

BACKGROUND: Midaortic syndrome (MAS) is a rare condition characterized by stenosis of the abdominal aorta. Patients with disease refractory to medical management will usually require either endovascular therapy or surgery with use of prosthetic graft material for bypass or patch angioplasty. We report our early experience with a novel approach using a tissue expander (TE) to lengthen the normal native arteries in children with MAS, allowing primary aortic repair without the need for prosthetic graft material...

A 5-year-old girl with Aicardi syndrome and microphthalmia with cyst of the OD presented with progressive enlargement of the cyst causing pain. Microophthalmia with inferior cyst (35 × 25 × 12 mm) was noted at birth, and Aicardi syndrome was diagnosed at 10 months by the presence of the classic triad of callosal agenesis, infantile spasms, and chorioretinal lacunae. She underwent enucleation with cyst resection, and subsequent reconstruction with a dermis fat graft. Histopathologic study revealed adenocarcinoma of the pigmented ciliary epithelium...

PURPOSE OF REVIEW: Given the extremely expensive nature of critical care medicine, it seems logical that intensivists should play an active role in designing efficient systems of care. The true value of intensivists, however, is not well defined. RECENT FINDINGS: Anesthesiologists have taken key roles in improving patient safety in the operating room. Anesthesia-related mortality rates have decreased from 20 deaths per 100 000 anesthetics in the early 1980s to less than one death per 100 000 currently...

High-throughput single-cell analysis is a challenging target for implementing advanced biomedical applications. An excellent candidate for this aim is label-free tomographic phase microscopy (TPM). In this paper, some of the methods used to obtain TPM are reviewed, analyzing advantages and disadvantages of each of them. Moreover, an alternative tomographic technique is described for live cells analysis, and future trends of the method are foreseen. In particular, by exploiting random rolling of cells while they are flowing along a microfluidic channel, it is possible to obtain phase-contrast tomography thus obtaining complete retrieval of both 3D-position and orientation of rotating cells...

BACKGROUND: Although gunshot-induced extremity fractures are typically not considered open fractures, there is controversy regarding wound management in the setting of operative fixation to limit infection complications. Previous studies have evaluated the need for a formal irrigation and debridement (I&D) prior to intra-medullary nailing (IMN) of gunshot-induced femur fractures but none have specifically evaluated tibias. By comparing primary IMN for tibial shaft fractures caused by low-velocity firearms additionally treated with a formal operative I&D (group 1) with those without an I&D (group 2), we sought to identify whether there are: differences in treatment group infection rates; particular fracture patterns more prone to infection; and patient characteristics more prone to infections...

BACKGROUND: Musculoskeletal trauma represents a large source of morbidity in low and middle human development index countries (LMHDICs). Open reduction and internal fixation (ORIF) of traumatic long bone fractures definitively manages these injuries and restores function when conducted safely and effectively. Surgical site infections (SSIs) are a common complication of operative fracture fixation, although the risks of infection are ill-defined in LMHDIC. PATIENTS AND METHODS: This study reviewed systematically all studies describing SSI after ORIF in LMDHICs...

The threshold anomaly of the phenomenological potential has been known for a long time in nuclear reactions at energies around the Coulomb barrier, where the connection between the real and imaginary potentials is well described by the dispersion relation. However, this connection is not clear yet for some weakly bound nuclear systems, especially for reactions induced by exotic radioactive nuclei. In this study, precise optical potentials of the halo nuclear system ^{6}He+^{209}Bi were extracted via ^{208}Pb(^{7}Li,^{6}He) transfer reactions with energies measured downward to the extremely sub-barrier region...

Using the unique capabilities of the Variable Density Turbulence Tunnel at the Max Planck Institute for Dynamics and Self-Organization, Göttingen, we report experimental measurements in classical grid turbulence that uncover oscillations of the velocity structure functions in the inertial range. This was made possible by measuring extremely long time series of up to 10^{10} samples of the turbulent fluctuating velocity, which corresponds to O(10^{7}) integral length scales. The measurements were conducted in a well-controlled environment at a wide range of high Reynolds numbers from R_{λ}=110 up to R_{λ}=1600, using both traditional hot-wire probes as well as the nanoscale thermal anemometry probe developed at Princeton University...

Precision searches for time-reversal symmetry violating interactions in polar molecules are extremely sensitive probes of high energy physics beyond the standard model. To extend the reach of these probes into the PeV regime, long coherence times and large count rates are necessary. Recent advances in laser cooling of polar molecules offer one important tool-optical trapping. However, the types of molecules that have been laser cooled so far do not have the highly desirable combination of features for new physics searches, such as the ability to fully polarize and the existence of internal comagnetometer states...

We identify a largely model-independent signature of dark matter (DM) interactions with nucleons and electrons. DM in the local galactic halo, gravitationally accelerated to over half the speed of light, scatters against and deposits kinetic energy into neutron stars, heating them to infrared blackbody temperatures. The resulting radiation could potentially be detected by the James Webb Space Telescope, the Thirty Meter Telescope, or the European Extremely Large Telescope. This mechanism also produces optical emission from neutron stars in the galactic bulge, and x-ray emission near the galactic center because dark matter is denser in these regions...

At the triple point of a repulsive screened Coulomb system, a fcc crystal, a bcc crystal, and a fluid phase coexist. At their intersection, these three phases form a liquid groove, the triple junction. Using confocal microscopy, we resolve the triple junction on a single-particle level in a model system of charged PMMA colloids in a nonpolar solvent. The groove is found to be extremely deep and the incommensurate solid-solid interface to be very broad. Thermal fluctuations hence appear to dominate the solid-solid interface...

Mixed adenoneuroendocrine carcinoma (MANEC) is defined as a tumor that has morphologically recognizable both adenocarcinoma and neuroendocrine carcinoma components comprising at least 30% of either components. MANEC occurring in the ampulla of Vater is extremely rare, and only 16 cases have been reported in the English language literature. In the present report, we describe the first case of MANEC of the ampulla of Vater with immunocytochemical analyses. An 82-year-old Japanese male was incidentally found to have a tumorous lesion in the ampulla of Vater...

Thiols and primary aliphatic amines (PAA) are ubiquitous and extremely important species in biological system. They have performed significant interplaying roles in complex biological events. A single fluorescent probe differentiating both thiol and PAA can contribute to understanding the intrinsic inter-relationship of thiols and PAA in biological processes. Herein, we rationally constructed the first fluorescent probe that can respond to thiols and PAA in different fluorescence channels. The probe exhibited high selectivity and sensitivity to thiols and PAA...

REVIEW
Janet Treasure, Monica Leslie, Rayane Chami, Fernando Fernández-Aranda
Explanatory models for eating disorders have changed over time to account for changing clinical presentations. The transdiagnostic model evolved from the maintenance model, which provided the framework for cognitive behavioural therapy for bulimia nervosa. However, for many individuals (especially those at the extreme ends of the weight spectrum), this account does not fully fit. New evidence generated from research framed within the food addiction hypothesis is synthesized here into a model that can explain recurrent binge eating behaviour...
