PURPOSE: A case highlighting challenges with enoxaparin dosage and monitoring in obese patients is presented. SUMMARY: A morbidly obese 22-year-old Caucasian female (height, 168 cm; weight, 322 kg; body mass index [BMI], 114 kg/m(2)) who presented to the emergency department with acute-onset dyspnea and hypoxia was empirically initiated on enoxaparin for suspected pulmonary embolism at the institution's standard maximum dosage (160 mg subcutaneously every 12 hours)...

HIV infection is in the large majority of cases established by a single variant and understanding the characteristics of successfully transmitted variants is relevant to prevention strategies. Few studies have investigated the viral determinants of mother-to-child transmission. To determine the impact of Gag-protease driven viral replication capacity on mother-to-child transmission, the replication capacities of 148 recombinant viruses encoding plasma derived Gag-protease from 53 non-transmitter mothers, 48 transmitter mothers and 47 infected infants were assayed in an HIV-1 inducible green fluorescent protein reporter cell line...

BACKGROUND: The Masquelet-induced-membrane technique is a commonly used method for treating segmental bone defects. However, there are no established clinical standards for management of the induced membrane before grafting. QUESTIONS/PURPOSES: Two clinically based theories were tested in a chronic caprine tibial defect model: (1) a textured spacer that increases the induced-membrane surface area will increase bone regeneration; and (2) surgical scraping to remove a thin tissue layer of the inner induced-membrane surface will enhance bone formation...

Purpose. Patients with anaplastic thyroid cancer have a very high death rate. In contrast, deaths from non-anaplastic thyroid cancer are much less common. The genetic alterations in fatal non-anaplastic thyroid cancers have not been reported. <p>Experimental Design. We performed next-generation sequencing of 410 cancer genes from 57 fatal non-anaplastic thyroid primary cancers. Results were compared to The Cancer Genome Atlas study (TCGA study) of papillary thyroid cancers (PTC) and to the genomic changes reported in anaplastic thyroid cancer (ATC)...

A series of fluorescent silyl-fluorene molecules were synthesized and studied with respect to their photophysical properties and response toward ionizing neutron and gamma-ray radiation. Optically transparent and stable organic glasses were prepared from these materials using a bulk melt-casting procedure. The prepared organic glass monoliths provided fluorescence quantum yields and radiation detection properties exceeding the highest-performing benchmark materials such as solution-grown trans-stilbene crystals...

Species differences in perception have been linked to divergence in gross neuroanatomical features of sensory pathways. The anatomical and physiological basis of evolutionary change in sensory processing at cellular and circuit levels, however, is poorly understood. Here, we show how specific changes to a sensory microcircuit are associated with the evolution of a novel perceptual ability. In mormyrid fishes, the ability to detect variation in electric communication signals is correlated with an enlargement of the midbrain exterolateral nucleus (EL), and a differentiation into separate anterior (ELa) and posterior (ELp) regions...

Lipid production in the industrial microalga Nannochloropsis gaditana exceeds that of model algal species and can be maximized by nutrient starvation in batch culture. However, starvation halts growth, thereby decreasing productivity. Efforts to engineer N. gaditana strains that can accumulate biomass and overproduce lipids have previously met with little success. We identified 20 transcription factors as putative negative regulators of lipid production by using RNA-seq analysis of N. gaditana during nitrogen deprivation...

With recent advances in synthetic biology, CO2 could be utilized as a carbon feedstock by native or engineered organisms, assuming the availability of electrons. Two key enzymes used in autotrophic CO2 fixation are the CO dehydrogenase (CODH) and acetyl-CoA synthase (ACS), which form a bifunctional heterotetrameric complex. CODH/ACS can reversibly catalyze CO2 to CO, effectively enabling a biological water-gas shift reaction at ambient temperatures and pressures. The CODH/ACS complex is part of the Wood-Ljungdahl pathway (WLP) used by acetogens to fix CO2 and has been well characterized in native hosts...

BACKGROUND AND OBJECTIVES: Recent studies show that maternal obesity is associated with impaired offspring neurodevelopmental outcomes. The mechanism underlying the association is unclear. However, there is evidence to suggest a role for intra-uterine exposure to inflammation and insulin resistance (IR). We aimed to determine if maternal IR and inflammation were associated to fetal neurodevelopment as indicated by fetal heart rate variability (HRV), an index of fetal cardiac autonomic nervous system development...

OBJECTIVE: We examined data from a prospective study of risk factors that increase vulnerability or resilience, exacerbate distress, or foster recovery to determine whether risk factors accurately predict which individuals will later have high posttraumatic (PT) symptom levels and whether brief measures of risk factors also accurately predict later symptom elevations. METHOD: Using data from 129 adults exposed to traumatic injury of self or a loved one, we conducted receiver operating characteristic (ROC) analyses of 14 risk factors assessed by full-length measures, determined optimal cutoff scores, and calculated predictive performance for the nine that were most predictive...

Undifferentiated uterine sarcomas (UUS) are a heterogenous group of high-grade mesenchymal tumors. Although these tumors are highly aggressive, a subset of patients may experience long-term survival. These tumors have previously been divided morphologically into uniform and pleomorphic types. A previous study demonstrated that a mitotic index cutoff of 25 mitoses/10 high-power fields (corresponding to 11.16 mitotic figures/mm) could successfully divide tumors into 2 prognostic groups with significantly different overall survival...

BACKGROUND: Patients with atrial fibrillation (AF) have increased risk of thromboembolic events such as stroke and myocardial infarction (MI). Although it has been established that the efficacy of anticoagulation is superior to that of antiplatelet agents for stroke prophylaxis in AF, the optimal antithrombotic treatment remains uncertain for primary protection against MI. OBJECTIVES: The authors investigated the incidence of first-time MI in patients with AF according to antithrombotic treatment and estimated the risk of stroke and bleeding...

Brandon M Casper, Michele B Halvorsen, Thomas J Carlson, Arthur N Popper
Previous studies exploring injury response to pile driving in fishes presented exposure paradigms (>900 strikes) that emulated circumstances where fish would not leave an area being ensonified. Those studies did not, however, address the question of how many strikes are needed before injuries appear. Thus, the number of strikes paired with a constant single strike sound exposure level (SELss) that can cause injuries is not yet clear. In order to examine this question, hybrid striped bass (white bass Morone chrysops × striped bass Morone saxatilis) were exposed to 8-384 strikes in three different SELss treatments that generated different cumulative sound exposure level values...

REVIEW
Adiel Mamut, Kevin V Carlson
Urethral bulking aims to improve urethral mucosal coaptation, and thus outlet resistance, in an effort to limit stress-induced leakage. While efforts have been made to employ bulking agents to treat stress urinary incontinence (SUI) for more than 100 years, we remain wanting for the perfect injectable. Regardless of the agent studied, efficacy is modest at best, repeat injections are the norm, and long-term followup is conspicuously lacking. This treatment, however, fills an important need in our armamentarium against SUI, serving those patients who are not candidates for more invasive interventions and those with multiple prior failed surgeries...

REVIEW
Gregory G Bailly, Kevin V Carlson
The surgical management of female stress urinary incontinence (SUI) has evolved over the past century, using various techniques of retropubic colposuspensions and sling procedures. In the past two decades, the sling has become the mainstay of surgical treatment of SUI, with the synthetic midurethral sling (MUS) leading the way. With the recent concerns raised by the U.S. Food and Drug Administration (FDA) and Health Canada about the safety of vaginal surgery using mesh implants, including the MUS, urologists and gynecologists should be familiar with suitable alternatives, including the pubovaginal sling (PVS), which often incorporates autologous fascia...

REVIEW
Alex Kavanagh, May Sanaee, Kevin V Carlson, Gregory G Bailly
Surgical failure rates after midurethral sling (MUS) procedures are variable and range from approximately 8-57% at five years of followup. The disparity in long-term failure rates is explained by a lack of long-term followup and lack of a clear definition of what constitutes failure. A recent Cochrane review illustrates that no high-quality data exists to recommend or refute any of the different management strategies for recurrent or persistent stress urinary incontinence (SUI) after failed MUS surgery. Clinical evaluation requires a complete history, physical examination, and establishment of patient goals...
