OBJECTIVE: The risk of maternal and fetal mortality is high if cardiopulmonary arrest occurs during pregnancy. To assess the best position for maternal cardiopulmonary resuscitation (CPR), a prospective randomized crossover study was undertaken, involving basic life support mannequin-based simulation (BLS-MS) and a swine model of pulseless electrical activity (an unstable cardiac state) incorporating a fetal mannequin (PEA-FM). STUDY DESIGN: The BLS-MS (performed by certified rescuers) served to evaluate the quality of chest compressions in 30° left lateral tilt (LLT) and supine positions...

Victimization has been widely demonstrated to have negative consequences in minors. Most crimes against children go unreported and victims tend to reach adulthood without receiving any of the available specialized support. Studies have highlighted the unique role of school workers in early detection and reporting of possible cases of victimization, and have also found high rates of underreporting by school staff. The present study analyzes the underreporting of child and youth victimization suspicions among school staff and aims to identify variables related to its detection and reporting...

Micropropagated plants experience significant stress from rapid water loss when they are transferred from an in vitro culture to either greenhouse or field conditions. This is caused both by inefficient stomatal control of transpiration and the change to a higher light intensity and lower humidity. Understanding the physiological, vascular and biomechanical processes that allow micropropagated plants to modify their phenotype in response to environmental conditions can help to improve both field performance and plant survival...

The hippocampus is critical for producing stable representations of familiar spaces. How these representations arise is poorly understood, largely because changes to hippocampal inputs have not been measured during spatial learning. Here, using intracellular recording, we monitored inputs and plasticity-inducing complex spikes (CSs) in CA1 neurons while mice explored novel and familiar virtual environments. Inputs driving place field spiking increased in amplitude - often suddenly - during novel environment exploration...

Visual prostheses are now an available mobility aid for patients blinded by degenerative retinal diseases. However, the spatial resolution of existing devices is still insufficient to deliver normal levels of mobility vision without stimulation strategies which enable existing devices to deliver several different percepts per stimulation site. A stimulation strategy in which field shaping is achieved by incorporating multipolar (bipolar and tripolar) stimulation could convey additional information to a user of a visual prosthesis, as compared to monopolar stimulation, is investigated...

Wells are considered to be high-risk pathways for fluid leakage from geologic CO2 storage reservoirs, because breaches in this engineered system have the potential to connect the reservoir to groundwater resources and the atmosphere. Given these concerns, a few studies have assessed leakage risk by evaluating regulatory records, often self-reported, documenting leakage in gas fields. Leakage is thought to be governed largely by initial well-construction quality and the method of well abandonment. The geologic carbon storage community has raised further concerns because acidic fluids in the CO2 storage reservoir, alkaline cement meant to isolate the reservoir fluids from the overlying strata, and steel casings in wells are inherently reactive systems...

BACKGROUND: Critical limb ischemia (CLI) may be the consequence of chronic occluded popliteal artery aneurysm (PAA). Open repair (OR) offers better 5-year results than endovascular treatment, but in patients with severe comorbidities or unfit to OR, endovascular repair (ER) could represent a valid treatment option. The purpose of this retrospective study was to review our experience of endovascular popliteal aneurism repair (EVPAR) in patients with chronic occluded PAA. METHODS: The endpoints assessed were: 1- and 3-year primary and secondary patency rates, technical success, 30-day major adverse events, major amputation free-survival, re-intervention and survival rates...

BACKGROUND: Fournier's gangrene (FG) is a rapidly evolving necrotizing fasciitis of the perineum and the genital area, the scrotum as it most commonly affects man in the vast majority of cases. It is polymicrobial in origin, due to the synergistic action of anaerobes and aerobes and has a very high mortality. There are many predisposing factors including diabetes mellitus, alcoholism, immunosuppression, renal, and hepatic disease. The prognosis of the disease depends on a lot of factors including but not limited to patient age, disease extent, and comorbidities...

Gamma oscillation plays a role in binding process or sensory integration, a process by which several brain areas beside primary cortex are activated for higher perception of the received stimulus. Beta oscillation is also involved in interpreting received stimulus and occurs following gamma oscillation, and this process is known as gamma-to-beta transition, a process for neglecting unnecessary stimuli in surrounding environment. Gamma oscillation also associates with cognitive functions, memory and emotion...

OBJECTIVE: Stereotactic body radiotherapy (SBRT) for early-stage non-small-cell lung cancer (NSCLC) is the standard of care in medically inoperable patients. In very elderly patients, previous studies have shown SBRT to offer excellent local control, though with higher toxicities than in younger populations. We report our institutional experience using SBRT in the definitive management of NSCLC in patients ≥80years old. MATERIALS AND METHODS: Using an IRB-approved registry of 158 patients treated with definitive-intent lung SBRT for early-stage NSCLC at our institution between 2010 and 2016, 31 consecutively treated patients ≥80years of age were identified...
