Domestic Violence: The Use of Pro-Arrest Policies and Mandatory Prosecutions

Domestic violence is a crime that affects millions of American families. Traditionally,domestic violence was recognized by the general population and the courts as being aprivate issue that should be handled within the boundaries of the family. Lawenforcement and the judicial system played a minimal role and generally maintained ahands off policy in relation to domestic violence cases. Adding to this mentality ofprivacy, the Fourth Amendment to the Constitution prohibits entering a residence withoutprobable cause. The Minneapolis domestic violence experiment attempted to measurewhich police response was most beneficial. In order to empower victims and bringabusers to justice, state governments should adopt a pro-arrest policy alongside amandatory prosecution policy

Augmentative and Alternative Communication in the Intensive Care Unit: A Service Delivery Model

Patients in the intensive care unit (ICU) often find it difficult or impossible to verbally communicate due to mechanical ventilation, tracheostomy tubes or increased fatigue and delirium. Augmentative and alternative communication (AAC) can provide ICU patients with a way to communicate during their ICU admittance. However, few hospitals currently have a systematic service delivery model in place for providing AAC tools and supports to ICU patients. This resource manual provides an outline for creating and implementing an AAC service delivery model along with AAC materials and resources appropriate for an ICU. Explanations of how each material is used, who they are appropriate for and how they can modify are provided for each AAC method discussed. Providing a detailed and systematic AAC service delivery model, such as the one outlined in this resource manual, allows ICU patients to effectively and efficiently communicate during a frightening and anxiety-provoking time

Mainstream Tablets as Speech Generating Devices: Considerations in Decision Making

In the last several years, the field of augmentative and alternative communication (AAC) has seen significant technological advances that are both innovative and exciting. One of the main advances in technology comes in AAC applications on mainstream tablet devices like iPads. Tablet devices with AAC applications are being explored as an alternative to dedicated speech generating devices due to cost and convenience. But, before choosing between a mainstream tablet AAC device and a dedicated AAC device, there are several foundational elements of AAC to be understood. All of the AAC basics and considerations should be part of the assessment process that determines the most appropriate device for an individual in need of an AAC device because not all devices work for everyone. Language representation method, vocabulary organization, and hardware differences are some of the main foundational elements of AAC that should be considered in the assessment process. Once the basics are established, considerations such as cost, insurance coverage, available accessories, and social factors must be explored before choosing between the devices. Overall, it is important to consider all aspects of AAC when choosing an appropriate device for an individual

Metastatic Squamous Cell Carcinoma in a Northern Brown Bandicoot (<i>Isoodon macrourus</i>)

Aside from a handful of notable exceptions, neoplasia is not reported as a major cause of mortality in wild animal populations and often goes undetected. For northern brown bandicoots specifically, there are few reported tumors in the literature and on file in the Australian Registry of Wildlife Health. This report describes a case of squamous cell carcinoma in a northern brown bandicoot (Isoodon macrourus), with metastases to the draining lymph nodes and lung. This neoplasm consisted predominantly of well-differentiated squamous cells and multifocal keratin pearls, with areas possibly consistent with epithelial to mesenchymal transition, as identified by positive immunohistochemical staining by both pancytokeratin (AE1/AE3) and vimentin. Additional investigations were negative for bandicoot papillomatosis carcinomatosis viruses

Regulated expression of HCN channels and cAMP levels shape the properties of the h current in developing rat hippocampus.

The hyperpolarization-activated current (I(h)) contributes to intrinsic properties and network responses of neurons. Its biophysical properties depend on the expression profiles of the underlying hyperpolarization-activated, cyclic nucleotide-gated (HCN) channels and the presence of cyclic AMP (cAMP) that potently and differentially modulates I(h) conducted by HCN1, HCN2 and/or HCN4. Here, we studied the properties of I(h) in hippocampal CA1 pyramidal cells, the developmental evolution of the HCN-subunit isoforms that contribute to this current, and their interplay with age-dependent free cAMP concentrations, using electrophysiological, molecular and biochemical methods. I(h) amplitude increased progressively during the first four postnatal weeks, consistent with the observed overall increased expression of HCN channels. Activation kinetics of the current accelerated during this period, consonant with the quantitative reduction of mRNA and protein expression of the slow-kinetics HCN4 isoform and increased levels of HCN1. The sensitivity of I(h) to cAMP, and the contribution of the slow component to the overall I(h), decreased with age. These are likely a result of the developmentally regulated transition of the complement of HCN channel isoforms from cAMP sensitive to relatively cAMP insensitive. Thus, although hippocampal cAMP concentrations increased over twofold during the developmental period studied, the coordinated changes in expression of three HCN channel isoforms resulted in reduced effects of this signalling molecule on neuronal h currents

E-Predict: a computational strategy for species identification based on observed DNA microarray hybridization patterns

DNA microarrays may be used to identify microbial species present in environmental and clinical samples. However, automated tools for reliable species identification based on observed microarray hybridization patterns are lacking. We present an algorithm, E-Predict, for microarray-based species identification. E-Predict compares observed hybridization patterns with theoretical energy profiles representing different species. We demonstrate the application of the algorithm to viral detection in a set of clinical samples and discuss its relevance to other metagenomic applications

Aligning Medical Student Curriculum with Practice Quality Goals: Impacts on Quality Metrics and Practice Capacity for Students

The practice of medicine occurs primarily in the ambulatory environment where providers have many competing demands, including health record documentation and patient volume expectations. Subsequently, medical student education has not been a priority for providers, health systems, or community practices. Yet, accrediting and professional organizations, such as the Association of American Medical Colleges, American Academy of Family Physicians, Ambulatory Pediatric Association, Society of General Internal Medicine, and the Liaison Committee on Medical Education, recommend education in ambulatory settings

Enhanced expression of a specific hyperpolarization-activated cyclic nucleotide-gated cation channel (HCN) in surviving dentate gyrus granule cells of human and experimental epileptic hippocampus.

Changes in the expression of ion channels, contributing to altered neuronal excitability, are emerging as possible mechanisms in the development of certain human epilepsies. In previous immature rodent studies of experimental prolonged febrile seizures, isoform-specific changes in the expression of hyperpolarization-activated cyclic nucleotide-gated cation channels (HCNs) correlated with long-lasting hippocampal hyperexcitability and enhanced seizure susceptibility. Prolonged early-life seizures commonly precede human temporal lobe epilepsy (TLE), suggesting that transcriptional dysregulation of HCNs might contribute to the epileptogenic process. Therefore, we determined whether HCN isoform expression was modified in hippocampi of individuals with TLE. HCN1 and HCN2 expression were measured using in situ hybridization and immunocytochemistry in hippocampi from three groups: TLE with hippocampal sclerosis (HS; n = 17), epileptic hippocampi without HS, or non-HS (NHS; n = 10), and autopsy material (n = 10). The results obtained in chronic human epilepsy were validated by examining hippocampi from the pilocarpine model of chronic TLE. In autopsy and most NHS hippocampi, HCN1 mRNA expression was substantial in pyramidal cell layers and lower in dentate gyrus granule cells (GCs). In contrast, HCN1 mRNA expression over the GC layer and in individual GCs from epileptic hippocampus was markedly increased once GC neuronal density was reduced by &gt;50%. HCN1 mRNA changes were accompanied by enhanced immunoreactivity in the GC dendritic fields and more modest changes in HCN2 mRNA expression. Furthermore, similar robust and isoform-selective augmentation of HCN1 mRNA expression was evident also in the pilocarpine animal model of TLE. These findings indicate that the expression of HCN isoforms is dynamically regulated in human as well as in experimental hippocampal epilepsy. After experimental febrile seizures (i.e., early in the epileptogenic process), the preserved and augmented inhibition onto principal cells may lead to reduced HCN1 expression. In contrast, in chronic epileptic HS hippocampus studied here, the profound loss of interneuronal and principal cell populations and consequent reduced inhibition, coupled with increased dendritic excitation of surviving GCs, might provoke a "compensatory" enhancement of HCN1 mRNA and protein expression

Localization of HCN1 channels to presynaptic compartments: novel plasticity that may contribute to hippocampal maturation.

Increasing evidence supports roles for the current mediated by hyperpolarization-activated cyclic nucleotide-gated (HCN) channels, I(h), in hippocampal maturation and specifically in the evolving changes of intrinsic properties as well as network responses of hippocampal neurons. Here, we describe a novel developmental plasticity of HCN channel expression in axonal and presynaptic compartments: HCN1 channels were localized to axon terminals of the perforant path (the major hippocampal afferent pathway) of immature rats, where they modulated synaptic efficacy. However, presynaptic expression and functions of the channels disappeared with maturation. This was a result of altered channel transport to the axons, because HCN1 mRNA and protein levels in entorhinal cortex neurons, where the perforant path axons originate, were stable through adulthood. Blocking action potential firing in vitro increased presynaptic expression of HCN1 channels in the perforant path, suggesting that network activity contributed to regulating this expression. These findings support a novel developmentally regulated axonal transport of functional ion channels and suggest a role for HCN1 channel-mediated presynaptic I(h) in hippocampal maturation
