Objectives Breaking bad news can be a very distressing situation for both patients and physicians. Physician communication behavior should therefore match patients' communication preferences. The aim of this study was to characterize the content of bad news from the patients' perspective. Patients' preferences for communication of bad news as well as the fit to communication behavior displayed by physicians were also investigated. Finally, consequences of a mismatch between patients' preferences and physician communication were investigated in relation to psychological distress in patients...

Venous thromboembolism (VTE) is a well-known and feared complication following foot and ankle surgery, as it is a source of morbidity and mortality in the perioperative phase. The most recent CHEST guidelines recommended against the use of chemoprophylaxis and the majority of the literature has found a low incidence of VTE following foot and ankle surgery. Some authors prefer screening patients for risk factors and recommend the use of chemoprophylaxis on a case-by-case basis. Interestingly, studies that found high incidence of VTE were unable to determine a statistically significant difference between the prophylaxis and placebo groups...

We prospectively evaluated the surgical, audiologic, and quality-of-life outcomes in 5 patients-2 men and 3 women, aged 22 to 64 years (mean: 41.8)-who were implanted with the Sophono Alpha 2 MPO Processor. The indications for implantation of this bone-conduction device included recurrent ear canal infections with hearing aids (n = 3), single-sided deafness (n = 1), and patient preference in view of difficulty using a conventional hearing aid (n = 1). In addition to the patient with single-sided deafness, 3 patients had a bilateral mixed hearing loss and 1 had a bilateral conductive hearing loss...

A recent study reported that heat stress stimulates osteogenesis in an in vivo rat model using alginate gel and magnetite cationic liposomes. However, for clinical use, the efficacy for promoting osteogenesis needs to be investigated using clinically approved materials, and preferably with animals larger than rats. The aim of this study was to evaluate multiple heat stimuli-triggered osteogenesis in rat tibial defect models using already clinically applicable materials (Resovist® and REGENOS®) and determine the efficacy also in the rabbit...

A thin elastic sheet lying on a soft substrate develops wrinkled patterns when subject to an external forcing or as a result of geometric incompatibility. Thin sheet elasticity and substrate response equip such wrinkles with a global preferred wrinkle spacing length and with resistance to wrinkle curvature. These features are responsible for the liquid crystalline smectic-like behaviour of such systems at intermediate length scales. This insight allows better understanding of the wrinkling patterns seen in such systems, with which we explain pattern breaking into domains, the properties of domain walls and wrinkle undulation...

A previously healthy 7-month-old male infant presented for evaluation of fever, deceased oral intake, and intermittent noisy breathing. Physical examination revealed neck tenderness. Soft tissue neck radiographs and computed tomography (CT) scan supported a diagnosis of retropharyngeal swelling with extension to the superior mediastinum. Surgical exploration was planned, and endotracheal intubation was performed in the operating room. Significant cardiorespiratory derangements developed immediately after the tracheal tube was inserted, including hypotension, hypoxia, and bradycardia with signs of cardiac ischemia...

AbstractWe sought to identify independent, nonacademic predictors of medical and nursing student intent to migrate abroad or from rural to urban areas after graduation in low- and middle-income countries (LMIC). This was a cross-sectional survey of 3,199 first- and final-year medical and nursing students at 16 training institutions in eight LMIC. Questionnaires assessed demographics, career intentions, and preferences regarding selected career, location, and work-related attributes. Using principal component analysis, student preferences were reduced into four discrete categories of priorities: 1) work environment resources, 2) location livability, 3) altruistic job values, and 4) individualistic job values...

Exposure to ochratoxin A (OTA), a possible human carcinogen, leads to many different DNA mutations. As a first step toward understanding the structural basis of OTA-induced mutagenicity, the present work uses a robust computational approach and a slipped mutagenic intermediate model previously studied for C(8)-dG aromatic amine adducts to analyze the conformational features of post-replication 2-base deletion DNA duplexes containing OT-dG, the major OTA lesion at the C(8) position of guanine. Specifically, a total of 960 ns of molecular dynamics simulations (excluding trial simulations) were carried out on four OT-dG ionization states in three sequence contexts within oligomers containing the NarI recognition sequence, a known hotspot for deletion mutations induced by related adducts formed from known carcinogens...

Lung surfactant proteins (SP) play critical roles in surfactant function and innate immunity. SP-A and SP-D, members of the collectin family of C-type lectins, exhibit distinct ligand specificities, effects on surfactant structure, and host defense functions despite extensive structural homology. SP-A binds to dipalmitoylphosphatidylcholine (DPPC), the major surfactant lipid component, but not phosphatidylinositol (PI), whereas SP-D shows the opposite preference. Additionally, SP-A and SP-D recognize widely divergent pathogen-associated molecular patterns...

REVIEW
Helmut Plattner
During evolution, the cell as a fine-tuned machine had to undergo permanent adjustments to match changes in its environment, while "closed for repair work" was not possible. Evolution from protists (protozoa and unicellular algae) to multicellular organisms may have occurred in basically two lineages, Unikonta and Bikonta, culminating in mammals and angiosperms (flowering plants), respectively. Unicellular models for unikont evolution are myxamoebae (Dictyostelium) and increasingly also choanoflagellates, whereas, for bikonts, ciliates are preferred models...

BACKGROUND: Fusarium graminearum is the main pathogen of Fusarium Head Blight (FHB), a worldwide plant disease and one of the major wheat diseases in China. The control of the FHB is mainly dependent on the application of DMIs fungicides. Fungal sterol 14α-demethylase enzymes (CYP51) are the main target for DMIs fungicides. In order to investigate the binding mechanism between azoles and CYP51B in F.graminearum, the molecular modeling study and biological evaluation were performed. RESULTS: Firstly, the homology model based on the crystal structure of Aspergillus fumigatus was built...

Using the classical emulsified system and the monomolecular film technique, the substrate specificity of recombinant Gibberella zeae lipase (rGZEL) that originates from Gibberella zeae was characterized in detail. Under the emulsified reaction system, both phospholipase and glycolipid hydrolytic activities were observed, except for the predominant lipase activity. The optimum conditions for different activity exhibition were also determined. Compared with its lipase activity, a little higher ratio of glycolipid hydrolytic activity (0...

We investigated nursing behavior on the Hawaiian breeding grounds for first year humpback whale (Megaptera novaeangliae) calves. We observed and video-documented underwater events with nursing behavior from five different whale groups. The observed nursing events include behaviors where a calf positions itself at a 30-45° angle to the midline of the mother's body, with its mouth touching her mammary slit (i.e., suckling position). On two occasions, milk in the water column was recorded in close proximity to a mother/calf pair, and on one occasion, milk was recorded 2...
