High trait anger is associated with more severe alcohol use problems, and alcohol has been found to facilitate aggressive behavior among individuals with high trait anger. Treatments focused on a sample with alcohol use disorder with elevated anger could reduce alcohol use problems, as well as violence and aggression. We sought to examine the efficacy of interpretation bias modification for hostility (IBM-H) in a sample with high trait anger and alcohol use disorder (AUD). Fifty-eight individuals with AUD and elevated trait anger were randomly assigned to eight web-based sessions (two per week) of IBM-H or a healthy video control condition (HVC)...

Little is known about current practices in high-value care (HVC) bedside teaching. A lack of instruments for measuring bedside HVC behaviors confounds efforts to assess the impact of curricular interventions. The authors aimed to define observable HVC concepts by developing an instrument to measure the content and frequency of HVC discussions.The authors developed the HVC Rounding Tool in four iterative phases, using Messick's validity framework. Phases 1 and 2 were designed to collect evidence of content validity, Phases 3 and 4 to collect evidence of response process and internal structure...

Different neuronal types within brain motor areas contribute to the generation of complex motor behaviors. A widely studied songbird forebrain nucleus (HVC) has been recognized as fundamental in shaping the precise timing characteristics of birdsong. This is based, among other evidence, on the stretching and the "breaking" of song structure when HVC is cooled. However, little is known about the temperature effects that take place in its neurons. To address this, we investigated the dynamics of HVC both experimentally and computationally...

The neural basis of how learned vocalizations change during development and in adulthood represents a major challenge facing cognitive neuroscience. This plasticity in the degree to which learned vocalizations can change in both humans and songbirds is linked to the actions of sex steroid hormones during ontogeny but also in adulthood in the context of seasonal changes in birdsong. We investigated the role of steroid hormone signaling in the brain on distinct features of birdsong using adult male canaries (Serinus canaria), which show extensive seasonal vocal plasticity as adults...

A fast, neuromodulatory role for estrogen signaling has been reported in many regions of the vertebrate brain. Regional differences in the cellular distribution of aromatase (estrogen synthase) in several species suggest that mechanisms for neuroestrogen signaling differ between and even within brain regions. A more comprehensive understanding of neuroestrogen signaling depends on characterizing the cellular identities of neurons that express aromatase. Calcium-binding proteins such as parvalbumin and calbindin are molecular markers for interneuron subtypes, and are co-expressed with aromatase in human temporal cortex...

During typical late-postnatal CNS development, net reductions in dendritic spine densities are associated with activity-dependent learning. Prior results showed agonist exposure in young animals increased spine densities in a subset of song regions while adult exposures did not, suggesting endocannabinoid signaling regulates dendritic spine dynamics important to vocal development. Here we addressed this question using the CB1 receptor-selective antagonist SR141716A (SR) to disrupt endocannabinoid signaling both during and after vocal learning...

Birdsong is a complex behavior that exhibits hierarchical organization. While the representation of singing behavior and its hierarchical organization has been studied in some detail in avian cortical premotor circuits, our understanding of the role of the thalamus in adult birdsong is incomplete. Using a combination of behavioral and electrophysiological studies, we seek to expand on earlier work showing that the thalamic nucleus Uvaeformis (Uva) is necessary for the production of stereotyped, adult song in zebra finch (Taeniopygia guttata)...

BACKGROUND: Total knee arthroplasty is overall a very successful surgery, but complications do occur. These complications include aseptic loosening of the tibial component, and obese patients are among the highest risk group. High-viscosity cement (HVC) has been implicated as a possible cause for aseptic loosening of the tibial component. The purpose of this study was to evaluate the incidence of aseptic loosening of the tibial component in obese patients with the use of HVC and standard tibial tray...

Human immunodeficiency virus (HIV) and hepatitis C virus (HCV) are prevalent infections in opiate-dependent patients. Opiate replacement treatment (ORT) with methadone or buprenorphine is associated with several important outcomes among patients with opiate dependence. However, little is known about outcomes in patients with HIV and/or HCV infections that are in ORT. Also, it is not well established whether the presence of HCV or HIV infection could be associated with higher methadone doses. This paper reanalyzes the database of PROTEUS study, using two principal variables: methadone dose and presence of HIV and/or HCV infection...

Male zebra finches produce a song consisting of a canonical sequence of syllables, learned from a tutor and repeated throughout its adult life. Much of the neural circuitry responsible for this behavior is located in the cortical premotor region HVC (acronym is name). In a recent study from our laboratory, we found that partial bilateral ablation of the medial portion of HVC has effects on the song that are qualitatively different from those of bilateral ablation of the lateral portion. In this report we describe a neural network organization that can explain these data, and in so doing suggests key roles for other brain nuclei in the production of song...

Sporadic porphyria cutanea tarda (PCT) is strongly associated with HCV infection in our population (1,2,3,4.) . Therapeutic options for PCT include phlebotomies and low-dose 4-aminoquinolines, which show high rates of disease remission. However, some PCT patients may present frequent relapses attributable to resistance/intolerability/poor adherence to conventional treatments and/or persistence of risk factors. In 2014 we reported the first case of a patient with active PCT and HCV-HIV co-infection cured with direct antiviral agents (DAAs) (5) ...

The sequential activation of neurons has been observed in various areas of the brain, but in no case is the underlying network structure well understood. Here we examined the circuit anatomy of zebra finch HVC, a cortical region that generates sequences underlying the temporal progression of the song. We combined serial block-face electron microscopy with light microscopy to determine the cell types targeted by HVC(RA) neurons, which control song timing. Close to their soma, axons almost exclusively targeted inhibitory interneurons, consistent with what had been found with electrical recordings from pairs of cells...

BACKGROUND: Rising and burdensome health care costs have driven interest in the practice of high-value care (HVC) and have inspired calls for increased HVC training across all levels of medical education, including among undergraduate medical students. CONTEXT: Classroom-based HVC curricula targeted to medical students have not been previously described in the medical literature. INNOVATION: We developed and evaluated a workshop comprising a lecture, a small-group exercise and a group discussion to instruct medical students on interpreting cost-effectiveness analyses (CEA), applying CEA to patient care and discussing the cost of care with patients...

Bacterial infection of tattoos remains a common complication. Pyogenic bacteria can cause infections shortly after the tattoo is made. Severity of infection varies from minor to major, ultimately with life-threatening septicemia. Viral infections may be introduced, i.e. HVB, HVC, and HIV. The risk of infection depends on the following triad: microbial pathogen and its aggressiveness, individual resistance of the tattooed, and inoculation and exposures by the tattoo needle and in the tattoo parlor. Some infectious risks can be controlled...

INTRODUCTION: Detection of hepatitis C virus (HCV) RNA and the HCV core antigen assay (HCV-Ag) are reliable techniques for the diagnosis of active and chronic HCV infection. Our aim was to evaluate the HCV-Ag assay as an alternative to quantification of HVC RNA. METHODS: A comparison was made of the sensitivity and specificity of an HCV-Ag assay (204 serum samples) with those of a PCR assay, and the correlation between the two techniques was determined. RESULTS: The sensitivity and specificity of HCV-Ag was 76...
