BACKGROUND: The ultrasound-guided transversus abdominis plane (TAP) block has been demonstrated as a useful analgesia technique in lower-abdomen surgeries. We hypothesized that it could be the principal anesthesia technique for end-stage renal disease (ESRD) patients undergoing peritoneal dialysis (PD) catheter (PDC) implantation using the open dissection method. METHODS: This was a single-center, prospective, randomized, and double-blinded study. All eligible patients were randomized into 2 groups: the TAP block group (n = 20) and the local anesthetic infiltration (LAI) group (n = 20)...

Electric field-induced p-n junctions are often used to realize peculiar functionalities in various materials. This method can be applied not only to conventional semiconductors but also to carbon nanotubes, graphene, and organic semiconductors to which the conventional chemical doping method is difficult to be applied. Transition-metal dichalcogenides (TMDs) are one of such materials where the field-induced p-n junctions play crucial roles in realizing solar cell and light-emitting diode operations as well as circularly polarized electroluminescence...

Network science is booming! While the insights and images afforded by network mapping techniques are compelling, implementing the techniques is often daunting to researchers. Thus, the aim of this tutorial is to facilitate implementation in the context of GIMME, or group iterative multiple model estimation. GIMME is an automated network analysis approach for intensive longitudinal data. It creates person-specific networks that explain how variables are related in a system. The relations can signify current or future prediction that is common across people or applicable only to an individual...

Recently, hairpin stacking circuits (HSC) based on toehold-mediated strand displacement have been engineered to detect nucleic acids and proteins. However, the three metastable hairpins in a HSC system can potentially react non-specifically in the absence of a catalyst, limiting its practical application. Here, we developed a unique hairpin design guideline to eliminate circuit leakage of HSC, and the high-performance HSC was successfully implemented on logic gate building and biosensing. We began by analyzing the sources of circuit leakage and optimizing the toehold lengths of hairpins in the HSC system based on the surface plasmon resonance (SPR) technique...

BACKGROUND: The combination of neurologic deformity of the ankle and foot with osteomyelitis is a therapeutic challenge. We investigated the role of Ilizarov with regard to eradication of infection, correction of deformities and improvement of patient function. METHODS: We retrospectively reviewed 77 patients (77 feet) with neurologic deformity of the ankle and foot with osteomyelitis treated sequentially in 3 stages by Ilizarov method. The 3 stages were (1) active debridement and Ilizarov stabilization, (2) further strengthening of Ilizarov fixator and active osteosynthesis consisting of strategies like arthrodesis, osteotomy distraction, bone transport, or combination thereof, (3) consolidation of fusion/regeneration achieved in second stage...

Congenital diaphragmatic hernia (CDH) remains one of the major challenges in neonatal surgery. Survival rate has increased in the last decades mainly due to perinatal care and surgical technique improvements. Classically, a laparotomy has been performed after cardiovascular and respiratory stabilization. Introduction of thoracoscopy in the repair of CDH brought the known advantages of reduced postoperative pain and better cosmesis. However, its safety and effectiveness have been questioned in the last few years...

BACKGROUND: Extracellular volume (ECV) by T1 mapping requires the contrast agent distribution to be at equilibrium. This can be achieved either definitively with a primed contrast infusion (infusion ECV), or sufficiently with a delay postbolus (bolus-only ECV). For large ECV, the bolus-only approach measures higher than the infusion ECV, causing some uncertainty in diseases such as amyloidosis. PURPOSE: To characterize the relationship between the bolus-only and current gold-standard infusion ECV in patients with amyloidosis...

Injury to the nerves of the aortic- and superior hypogastric plexuses during retroperitoneal surgery often results in significant post-operative complications, including retrograde ejaculation and/or loss of seminal emission in males. Although previous characterizations of these plexuses have done well to provide a basis for understanding the typical anatomy, additional research into the common variations of these plexuses could further optimize nerve-sparing techniques for retroperitoneal surgery. To achieve this, the present study aimed to document the prevalence and positional variability of the infrarenal lumbar splanchnic nerves (LSNs) through gross dissection of 26 human cadavers...

REVIEW
Shivani Ahlawat, Laura M Fayad
Diffusion-weighted imaging (DWI) is a fast, non-contrast technique that is readily available and easy to integrate into an existing imaging protocol. DWI with apparent diffusion coefficient (ADC) mapping offers a quantitative metric for soft tissue evaluation and provides information regarding the cellularity of a region of interest. There are several available methods of performing DWI, and artifacts and pitfalls must be considered when interpreting DWI studies. This review article will review the various techniques of DWI acquisition and utility of qualitative as well as quantitative methods of image interpretation, with emphasis on optimal methods for ADC measurement...

INTRODUCTION: Even if different surgical approaches for total knee arthroplasty are well known since decades, the standard medial parapatellar incision remains the most common one; general agreement about significant advantages with minimally invasive techniques is lacking. Furthermore, the surgical stress effect on the organism has always been analyzed through blood inflammatory parameters. This study aim was to compare the standard and subvastus approaches, using the salivary cortisol in particular as measure for systemic surgery-related stress...

PURPOSE: Previous studies have illustrated the clinical utility of the addition of intraoperative magnetic resonance imaging (iMRI) to conventional microsurgical resection. While iMRI requires initial capital cost investment, long-term reduction in costly follow-up management and reoperation costs may prove economically efficacious. The objective of this study is to investigate the cost-effectiveness of the addition of iMRI utilization versus conventional microsurgical techniques in focal cortical dysplasia (FCD) resection in pediatric patients with medically refractory epilepsy...

Purpose: The clinical utility of FDG-PET in diagnosing frontotemporal dementia (FTD) has been well demonstrated over the past decades. On the contrary, the diagnostic value of arterial spin labelling (ASL) MRI - a relatively new technique - in clinical diagnosis of FTD has yet to be confirmed. Using simultaneous PET/MRI, we evaluated the diagnostic performance of ASL in identifying pathological abnormalities in FTD (FTD) to determine whether ASL can provide similar diagnostic value as FDG-PET...

Reduction of the crosstalk between adjacent photonic components has been regarded as one of the most effective, yet most challenging approaches for increasing the packing density of photonic integrated circuits. Recently, extensive efforts have been devoted to this field, leading to a number of elaborate designs, such as waveguide supperlattice and nanophotonic cloaking, among others. Here we develop a simple and efficient crosstalk reduction approach for silicon-based nanophotonic circuits by introducing a periodic array of silicon strips between adjacent waveguides...
