PURPOSE: To determine the effects of the RF refocusing pulse profile on the magnitude of the transverse signal smoothness throughout the echo train in non-Carr-Purcell-Meiboom-Gill (nCPMG) single-shot fast spin echo (SS-FSE) imaging and to design an RF refocusing pulse that provides improved signal stability. THEORY AND METHODS: nCPMG SS-FSE quadratic phase modulation requires sufficiently high and uniform refocusing flip angle to achieve a stable signal. Typically, refocusing pulses used in SS-FSE sequences are designed for minimum duration to minimize echo spacing and as a consequence have poor selectivity...

Hernia repair is one of the most commonly performed surgical procedures worldwide, with a multi-billion dollar global market. Implant design remains a critical challenge for the successful repair and prevention of recurrent hernias, and despite significant progress, there is no ideal mesh for every surgery. This review summarizes the evolution of prostheses design toward successful hernia repair beginning with a description of the anatomy of the disease and the classifications of hernias. Next, the major milestones in implant design are discussed...

Fusing a lower resolution color image with a higher resolution monochrome image is a common practice in medical imaging. By incorporating spatial context and/or improving the signal-to-noise ratio, it provides clinicians with a single frame of the most complete information for diagnosis. In this paper, image fusion is formulated as a convex optimization problem that avoids image decomposition and permits operations at the pixel level. This results in a highly efficient and embarrassingly parallelizable algorithm based on widely available robust and simple numerical methods that realizes the fused image as the global minimizer of the convex optimization problem...

BACKGROUND: Transfascial suture passers (TSPs) are a commonly used surgical tool available in a wide array of tip configurations. We assessed the insertion force of various TSPs in an ex vivo porcine model. METHODS: Uniform sections of porcine abdominal wall were secured to a 3D-printed platform. Nine TSPs were passed through the abdominal wall both without and with prolene suture under the following scenarios: abdominal wall only and abdominal wall plus underlay ePTFE or composite ePTFE/polypropylene mesh...

This work elucidates the molecular binding mechanism of CO2 in [C4C1IM][PF6] ionic liquid (IL) and its interplay with the CO2 asymmetric stretch frequency ν3, and establishes computational protocols for the reliable construction of spectroscopic maps for simulating ultrafast 2D-IR data of CO2 solvated in ILs. While charge transfer drives the static frequency shift between different ionic liquids ( J. Chem. Phys. 2015 , 142 , 212425 ), we find here that electrostatic and Pauli repulsion effects dominate the dynamical frequency shift between different geometries sampled from the finite-temperature dynamics within a single ionic liquid...

The use and effectiveness of simulation with standardized patients in undergraduate and graduate nursing education programs is well documented. Simulation has been primarily used to develop health assessment skills. Evidence supports using simulation and standardized patients in psychiatric-mental health nurse practitioner (PMHNP) programs is useful in developing psychosocial assessment skills. These interactions provide individualized and instantaneous clinical feedback to the student from faculty, peers, and standardized patients...

SS-FSE is a fast technique that does not suffer from off-resonance distortions to the degree that EPI does. Unlike EPI, SS-FSE is ill-suited to diffusion weighted imaging (DWI) due to the Carr-Purcell-Meiboom-Geill (CPMG) condition. Non-CPMG phase cycling does accommodate SS-FSE and DWI but places constraints on reconstruction, which are resolved here through parallel imaging. Additionally, improved echo stability can be achieved by using short duration and highly selective DIVERSE radiofrequency pulses. Here, signal-to-noise ratio (SNR) comparisons between EPI and nCPMG SS-FSE acquisitions and reconstruction techniques give similar values...

The two hemispheres of the human brain differ functionally and structurally. Despite over a century of research, the extent to which brain asymmetry is influenced by sex, handedness, age, and genetic factors is still controversial. Here we present the largest ever analysis of subcortical brain asymmetries, in a harmonized multi-site study using meta-analysis methods. Volumetric asymmetry of seven subcortical structures was assessed in 15,847 MRI scans from 52 datasets worldwide. There were sex differences in the asymmetry of the globus pallidus and putamen...

BACKGROUND: Contaminated operative fields pose significant challenges for surgeons performing ventral hernia repair. Although biologic meshes have been utilized increasingly in these fields, recent evidence suggests that synthetic meshes represent a viable option. We analyzed the outcomes of biologic and synthetic mesh utilized in patients undergoing major ventral hernia repair in clean-contaminated/contaminated fields. METHODS: We conducted a multicenter, retrospective review of patients undergoing open ventral hernia repair in clean-contaminated/contaminated fields using biologic or synthetic mesh...

Root hairs are involved in water and nutrient uptake, and thereby in plant autotrophy. In legumes, they also play a crucial role in establishment of rhizobial symbiosis. To obtain a holistic view of Medicago truncatula genes expressed in root hairs and of their regulation during the first hours of the engagement in rhizobial symbiotic interaction, a high throughput RNA sequencing on isolated root hairs from roots challenged or not with lipochitooligosaccharides Nod factors (NF) for 4 or 20 h was carried out...

INTRODUCTION: Posterior component separation herniorrhaphy via transversus abdominis release (TAR) permits midline reapproximation of large fascial defects. To date, no report delineates the reduction in tensile force to reapproximate midline fascia following TAR. We hypothesized that open and laparoscopic TAR would provide similar reductions in midline reapproximation forces in a porcine model. METHODS: Under general anesthesia, a 20-cm midline laparotomy was created and bilateral lipocutaneous flaps were raised to expose the anterior rectus sheath...

INTRODUCTION: Per-oral endoscopic myotomy (POEM) is a less invasive therapy for achalasia with a shorter hospitalization but with similar short- and long-term outcomes as a laparoscopic Heller myotomy (LHM). Previous literature comparing POEM to LHM has focused primarily on postoperative outcome parameters such as complications, dysphagia scores and gastro-esophageal reflux severity. This study specifically compares postoperative pain following POEM to pain following LHM, the current gold-standard operation...

INTRODUCTION: Parastomal hernias are a complex surgical problem affecting a large number of patients. Recurrences continue to occur despite various methods of repair. We present a novel method of open parastomal hernia repair with retromuscular mesh reinforcement in a modified Sugarbaker configuration. METHODS: A full mildline laparotomy is performed and all adhesions are taken down. We then perform an open parastomal hernia repair by utilizing retromuscular dissection, posterior component separation via transversus abdominis release, and lateralization of the bowel utilizing a modified Sugarbaker mesh configuration within the retromuscular space...
