The investigation of wildlife gastrointestinal microbiomes by next-generation sequencing approaches is a growing field in microbial ecology and conservation. Such studies often face difficulties in sample preservation if neither freezing facilities nor liquid nitrogen (LQN) are readily available. Thus, in order to prevent microbial community changes because of bacterial growth after sampling, preservation buffers need to be applied to samples. However, the amount of microbial community variation attributable to the different preservation treatments and potentially affecting biological interpretation is hardly known...

BACKGROUND: A retained surgical item in patients (gossypiboma) is a persisting problem, despite consistent improvements and existing guidelines in counting instruments and sponges. Previous experiences with radiofrequency identification technology (RFID) tracking sponges show that it could represent an innovation, in order to reduce the criticism and increase the effectiveness during surgical procedures. We present an automated system that allows reduction of errors and improves safety in the operating room...

Group IV semiconductor optoelectronic devices are now possible by using strain-free direct band gap GeSn alloys grown on a Ge/Si virtual substrate with Sn contents above 9%. Here, we demonstrate the growth of Ge/GeSn core/shell nanowire arrays with Sn incorporation up to 13% and without the formation of Sn clusters. The nanowire geometry promotes strain relaxation in the Ge0.87Sn0.13 shell and limits the formation of structural defects. This results in room-temperature photoluminescence centered at 0.465 eV and enhanced absorption above 98%...

: 36 Background: More than one-third of adults in the United States are obese. Studies have shown that obesity-related comorbidities increase health care costs, but the effect of obesity on operating room utilization has not been completely evaluated. The purpose of our study was to examine how operative time (OPT) for common procedures in breast surgery is affected by patient weight. We expected that weight affected OPT more so for extensive procedures, such as axillary lymph node dissection (ALND) and mastectomy, than for minimally invasive procedures, such as lumpectomy and sentinel lymph node biopsy (SLNB)...

Online image guidance in the operating room using ultrasound imaging led to the resurgence of prostate brachytherapy in the 1980s. Here we describe the evolution of integrating MRI technology in the brachytherapy suite or operating room. Given the complexity, cost, and inherent safety issues associated with MRI system integration, first steps focused on the computational integration of images rather than systems. This approach has broad appeal given minimal infrastructure costs and efficiencies comparable with standard care workflows...

Advances in the field of quantum sensing mean that magnetic field sensors, operating at room temperature, are now able to achieve sensitivity similar to that of cryogenically cooled devices (SQUIDs). This means that room temperature magnetoencephalography (MEG), with a greatly increased flexibility of sensor placement can now be considered. Further, these new sensors can be placed directly on the scalp surface giving, theoretically, a large increase in the magnitude of the measured signal. Here, we present recordings made using a single optically-pumped magnetometer (OPM) in combination with a 3D-printed head-cast designed to accurately locate and orient the sensor relative to brain anatomy...

We sought to delineate factors of inferior vena cava filter placement associated with increased radiation and cost and difficult subsequent retrieval. In total, 299 procedures from August 2013 to December 2014, 252 in a fluoroscopy suite (FS) and 47 in the operating room (OR), were reviewed for radiation exposure, fluoroscopy time, filter type, and angulation. The number of retrieval devices and fluoroscopy time needed for retrieval were assessed. Multiple linear regression assessed the impact of filter type, procedure location, and patient and procedural variables on radiation dose, fluoroscopy time, and filter angulation...

OBJECTIVE: Unplanned hospital readmissions following surgical interventions are associated with adverse events and contribute to increasing health care costs. Despite numerous studies defining risk factors following lower extremity bypass surgery, evidence regarding readmission after endovascular interventions is limited. This study aimed to identify predictors of 30-day unplanned readmission following infrainguinal endovascular interventions. METHODS: We identified all patients undergoing an infrainguinal endovascular intervention in the targeted vascular module of the American College of Surgeons National Surgical Quality Improvement Program between 2012 and 2014...

STUDY DESIGN: This is a retrospective study. OBJECTIVE: Compare improvements in health status measures (HSMs) and surgical costs to determine whether use of more costly items has any relationship to clinical outcome and value in lumbar disc surgery. SUMMARY OF BACKGROUND DATA: Association between cost, outcomes, and value in spine surgery, including lumbar discectomy is poorly understood. Outcomes were calculated as difference in mean HSM scores between preoperative and postoperative timeframes...

BACKGROUND: There is increasing evidence that the physical environment of neonatal intensive care units (NICUs), including single-family rooms (SFRs) versus open-bay rooms (OPBYs), has tangible effects on vulnerable patients. The objective of this study was to illustrate the financial implications of SFR versus OPBY units by synthesizing and evaluating the evidence regarding the benefits and costs of each unit from a hospital perspective. METHODS: We assumed a hypothetical NICU with 40 beds in OPBY rooms, to be replaced with a new NICU with 32 SFRs and 8 OPBYs...

The current healthcare environment demands optimization of patient outcomes in addition to maximal cost efficiency. Restrictions on resident work hours have placed limitations on the amount of time that trainee physicians can spend on patient care. For the surgery resident, the consequence is less time spent in the operating room under the supervision of a senior surgeon, the cornerstone of Halsted's approach to resident surgeon education. The use of simulation in graduate medical education has gained significant traction as a way to provide trainees with exposure to various techniques and procedures before use on the general patient population...

Surgical site infections (SSIs) cost an estimated $27,288 per case. An analysis of the National Surgical Quality Improvement Program data at the University of Rochester Medical Center suggested that rates of SSIs could be lowered in comparison with both peers and baseline. The aim of this study was to reduce the number of SSIs to zero through the implementation of a "bundle" or a combination of practices. Meetings were held with the multidisciplinary care team that includes surgeons and staff from pediatric pharmacy, pediatric infectious diseases, anesthesia, and nursing to create a care bundle for all pediatric orthopaedic surgery patients...

OBJECTIVE: The objective of this project was to use an interdisciplinary approach to analyze strategies through simulation technology for improving patient flow in a pediatric hospital. BACKGROUND: Various statistics have been offered on the number of children admitted annually to hospitals. For administrators, particularly in smaller systems, the financial burden of equipping and staffing pediatric units often outweighs the moral desire to maintain a pediatric unit as a viable option for patients and pediatricians...

PURPOSE: A brain sized radio frequency (RF)-penetrable PET insert has been designed for simultaneous operation with MRI systems. This system takes advantage of electro-optical coupling and battery power to electrically float the PET insert relative to the MRI ground, permitting RF signals to be transmitted through small gaps between the modules that form the PET ring. This design facilitates the use of the built-in body coil for RF transmission and thus could be inserted into any existing MR site wishing to achieve simultaneous PET/MR imaging...

BACKGROUND AND AIMS: Emergence time, or the duration between incision closure and extubation, is costly nonoperative time. Efforts to improve operating room efficiency and identify trainee progress make such time intervals of interest. We sought to calculate the incidence of prolonged emergence (i.e., >15 min) for patients under the care of clinical anesthesia (CA) residents. We also sought to identify factors from resident training, medical history, anesthetic use, and anesthesia staffing, which affect emergence...
