Trends, Predictors, and Outcomes of Bleeding Complications After Mitral Transcatheter Edge-to-Edge Repair: TVT Registry Insights.

Background: Bleeding events after arterial transcatheter procedures are associated with increased morbidity and mortality. The frequency and clinical implications of bleeding after mitral transcatheter edge-to-edge repair (M-TEER) have not been well-studied.

Objectives: The authors sought to explore the association of in-hospital bleeding events after M-TEER with patient outcomes.

Graft-Versus-Host Disease: an Update on Functional Implications and Rehabilitation Interventions.

Purpose Of Review: Despite advances in treatment, chronic graft-versus-host disease (cGVHD) remains a highly morbid complication of allogeneic hematopoietic stem cell transplantation. Due to direct effects of the disease on specific body sites, and its treatment, patients lose function. This review summarizes the latest evidence surrounding how cGVHD affects function, and restorative interventions.

The Society of Thoracic Surgeons National Database 2016 Annual Report.

The art and science of outcomes analysis, quality improvement, and patient safety continue to evolve, and cardiothoracic surgery leads many of these advances. The Society of Thoracic Surgeons (STS) National Database is one of the principal reasons for this leadership role, as it provides a platform for the generation of knowledge in all of these domains. Understanding these topics is a professional responsibility of all cardiothoracic surgeons.

2H NMR study of dynamics of benzene-d6 interacting with humic and fulvic acids.

Samples of three humic acids and one fulvic acid with 1% loading of benzene-d(6) in sealed glass tubes have been studied with solid-state deuterium quadrupole-echo nuclear magnetic resonance spectroscopy. Calculated spectra combining three motional models, two isotropic models and a third more restricted small-angle wobble (SAW) motional model, are fit to the experimental spectra. One isotropic motion (ISO(v)) is assigned to vaporous benzene-d(6) due to the small line width, short T(1), and the loss of this component by about -25 °C when the temperature is lowered.

Optimized low-level liquid scintillation spectroscopy of 35S for atmospheric and biogeochemical chemistry applications.

Anthropogenic activities, dominated by emissions of sulfur dioxide (SO(2)), have perturbed the global sulfur (S) cycle. Uncertainties in timescales of S transport and chemistry in the atmosphere lead to uncertainties in the predicted impact of S emissions. Measurements of cosmogenic (35)S may potentially be used to resolve existing uncertainties in the photochemical and chemical transformation of S in the environment.

Discovery and measurement of an isotopically distinct source of sulfate in Earth's atmosphere.

Sulfate (SO(4)) and its precursors are significant components of the atmosphere, with both natural and anthropogenic sources. Recently, our triple-isotope ((16)O, (17)O, (18)O) measurements of atmospheric sulfate have provided specific insights into the oxidation pathways leading to sulfate, with important implications for models of the sulfur cycle and global climate change. Using similar isotopic measurements of aerosol sulfate in a polluted marine boundary layer (MBL) and primary sulfate (p-SO(4)) sampled directly from a ship stack, we quantify the amount of p-SO(4) found in the atmosphere from ships.

Massive hepatic congenital haemangioma: clinical dilemmas.

A case of massive hepatomegaly secondary to a hepatic congenital haemangioma in a preterm neonate is described. This infant died after withdrawal of neonatal intensive care support, following massive intracerebral haemorrhage. There remains considerable uncertainty regarding the classification of, and therapy for, hepatic vascular anomalies.

Infection after medical abortion: a review of the literature.

Medical abortion regimens have become widely used, but the frequency of infection after medical abortion is not well documented. This systematic review provides data on infectious complications after medical abortion. We searched Medline for articles written before July 2003 to determine the frequency of infection after medical abortion up to 26 weeks of gestation.

Ectopic pregnancy and medical abortion.

Objective: Medical abortion regimens have become more widely used to terminate early pregnancies. Medical abortion providers are concerned to diagnose and exclude women with ectopic pregnancy before initiating treatment, as with any early pregnancy termination. Yet, there is little information about whether the various pretreatment screening methods used are adequate.

Dispersion compensation for terahertz optical frequency comb generation.

We demonstrate dispersion compensation in a terahertz-span optical frequency comb generator by use of an intracavity prism pair. With partial compensation of the material dispersion of the lithium niobate modulator, the span of the comb increases from 3.0 to 4.

Terahertz optical frequency comb generation and phase locking of an optical parametric oscillator at 665 GHz.

We have achieved efficient electro-optic phase modulation at high frequencies in a resonant modulator cavity. We enhance modulation by matching the phase velocities of the optical and microwave fields in the modulator substrate and by placing the modulator inside an optical cavity that is resonant for the input optical beam and the generated sidebands. An optical frequency comb with a span of 3 THz and at a spacing of 17 GHz is generated with 1 W of microwave power.

Factors associated with dangerous behavior in forensic inpatients: results from a pilot study.

This study was designed to identify risk factors associated with violence within a forensic inpatient hospital setting. The primary purpose was to develop a screening tool to aid in the rapid identification of patients requiring high versus low security ward placement. Subjects included 232 consecutive admissions during a five-month period to a 300-bed forensic division within a public-sector psychiatric hospital.

Durations of extended mental rehearsals are remarkably reproducible in higher level human performances.

It has been extremely difficult to quantify temporal aspects of higher level human brain function. We have found that mental rehearsals of musical performance of several minutes duration provide such a measure in that they can be highly reproducible, varying to less than 1%. These remarkable results pose fundamental neurophysiological problems.

Mesial temporal neurons in the macaque monkey with responses selective for aspects of social stimuli.

Primates possess a sophisticated cognitive ability to interpret and respond to the social actions of conspecifics. Neurons in the temporal lobes of macaque monkeys which are selective for the appearance and motions of conspecifics have been described previously; the results reported here indicate that pathways which integrate such information converge in mesial temporal regions. Single neuron data from an alert macaque viewing moving pictures of other monkeys engaged in a variety of behaviors are presented.

A neuroethological framework for the representation of minds.

The cognition that constructs mental features such as intention, disposition, and character is an aspect of theory of mind. This aspect of representation of minds, which inherently has valence, is viewed from cognitive, evolutionary, and neural perspectives. It is proposed that this cognition is modular, and that it normally operates in association with a valence-free cognition able to represent mental states such as belief.

Response of neurons in the macaque amygdala to complex social stimuli.

The presence of neurons in macaque temporal cortex and amygdala which fire selectively in response to social stimuli has been demonstrated by several investigators. The extent to which such neuronal populations may respond to a broad range of social features, including expressive movements and interactions, has not been fully explored due to the difficulty of presenting such complex stimuli in a controlled fashion. We describe a method for presenting moving segments of macaque behavior, visual and auditory, to animal subjects during single unit recording.

Delayed intraperitoneal ureteric rupture following blunt abdominal trauma: case report.

Ureteric injury is uncommon and mostly follows penetrating trauma or surgical injury. Ureteric rupture following blunt abdominal trauma is rare, there being only a few reported cases. The case described here, in which blunt abdominal trauma resulted in delayed intraperitoneal rupture, appears to be the first report of this type of injury in blunt trauma.

A biological perspective on empathy.

During the evolution of the primate CNS, organization of neural activity has been shaped by the need for rapid and accurate evaluation of the motivations of others. Using a broad biological approach, the author considers empathy from evolutionary, ontogenetic, and neurophysiological viewpoints. Emotional communication follows a developmental course in primate evolution and in individuals: specialized neural activity and CNS organization subserve the interpretation of social signals.

Neurophysiology of limbic system pathways in the rat: projections from the amygdala to the entorhinal cortex.

We studied the responses of rat entorhinal neurons to electrical stimulation of the amygdala. Four main results were obtained: (1) excitatory postsynaptic potentials were recorded in entorhinal neurons in response to electrical stimulation of the amygdala. Cells in layers II, III and V of the entorhinal cortex were responsive.
