Risking Connection Trauma Training: A Pathway Toward Trauma-Informed Care in Child Congregate Care Settings

Despite the high prevalence of traumatic experiences and attachment disruptions among clients in child congregate care treatment settings, until recently there has been little formal training on trauma for staff serving this population. Staff trauma training is one important intervention for agencies aiming to implement trauma-informed care (TIC), a term describing an international trend in mental health care whereby treatment approaches and cultures recognize the pervasive impact of trauma and aim to ameliorate, rather than exacerbate, the effects of trauma. The current study examines the impact of the curriculum-based Risking Connection (RC) trauma training on the knowledge, beliefs, and behaviors of 261 staff trainees in 12 trainee groups at five child congregate care agencies. RC is one of several models used nationally and internationally as a pathway toward TIC culture change in human service organizations including residential treatment. For a subset of agencies, measures were collected at four different time points. Results showed an increase in knowledge about the core concepts of the RC training consistently across groups, an increase in beliefs favorable to TIC over time, and an increase in self-reported staff behavior favorable to TIC in the milieu. In addition, these findings suggest that the train-the-trainer (TTT) model of dissemination central to RC is effective at increasing beliefs favorable to TIC. Differences in posttraining changes between three agencies are qualitatively investigated and discussed as examples of the importance of organization-level factors in successful implementation of agency-wide interventions like RC. Implications for implementing RC and trauma-informed agency change are discussed.
Development of a Gaussia Luciferase-Based Human Norovirus Protease Reporter System: Cell Type-Specific Profile of Norwalk Virus Protease Precursors and Evaluation of Inhibitors

ABSTRACT Norwalk virus (NV) is the prototype strain of human noroviruses (HuNoVs), a group of positive-strand RNA viruses in the Caliciviridae family and the leading cause of epidemic gastroenteritis worldwide. Investigation of HuNoV replication and development of antiviral therapeutics in cell culture remain challenging tasks. Here, we present NoroGLuc, a HuNoV protease reporter system based on a fusion of NV p41 protein with a naturally secreted Gaussia luciferase (GLuc), linked by the p41/p22 cleavage site for NV protease (Pro). trans cleavage of NoroGLuc by NV Pro or Pro precursors results in release and secretion of an active GLuc. Using this system, we observed a cell type-specific activity profile of NV Pro and Pro precursors, suggesting that the activity of NV Pro is modulated by other viral proteins in the precursor forms and strongly influenced by cellular factors. NoroGLuc was also cleaved by Pro and Pro precursors generated from replication of NV stool RNA in transfected cells, resulting in a measurable increase of secreted GLuc. Truncation analysis revealed that the N-terminal membrane association domain of NV p41 is critical for NoroGLuc activity. Although designed for NV, a genogroup GI.1 norovirus, NoroGLuc also efficiently detects Pro activities from GII.3 and GII.4 noroviruses. At noncytotoxic concentrations, protease inhibitors ZnCl2 and Nα-p-tosyl-l-lysine chloromethyl ketone (TLCK) exhibited dose-dependent inhibitory effects on a GII.4 Pro by NoroGLuc assay. These results establish NoroGLuc as a pan-genogroup HuNoV protease reporter system that can be used for the study of HuNoV proteases and precursors, monitoring of viral RNA replication, and evaluation of antiviral agents. IMPORTANCE Human noroviruses are the leading cause of epidemic gastroenteritis worldwide. Currently, there are no vaccines or antiviral drugs available to counter these highly contagious viruses. These viruses are currently noncultivatable in cell culture. Here, we report the development of a novel cell-based reporter system called NoroGLuc that can be used for studying norovirus replication and also for screening/evaluation of antiviral agents. This system is based on the fusion between viral protein p41 and a naturally secreted Gaussia luciferase (GLuc) with a cleavage site that can be recognized by the viral protease. Cleavage of this fusion protein by the viral protease results in the release and secretion of an active GLuc. Using NoroGLuc, we demonstrated a cell type-specific activity profile of the viral protease and its precursors and dose-dependent inhibitory effects of two protease inhibitors. This novel reporter system should be useful in probing norovirus replication and evaluating antiviral agents.
Labeling of antibiotics for infection diagnosis.

UNLABELLED The high impact of infection on daily clinical practice has promoted research into better and more accurate diagnostic and therapeutic METHODS Localizing inflammation/infection with nuclear medicine techniques began over 40 years ago. Today, (67)Ga-scintigraphy, (99m)Tc-nanocolloid, (111)In and (99m)Tc in vitro labeled leukocytes, and monoclonal antigranulocyte antibodies are widely available for this purpose. While these methods are useful for localizing inflammation, they cannot always differentiate septic from aseptic processes. The ideal properties of an agent for diagnosing infection include: high specificity, early diagnosis, rapid blood clearance, ease of preparation, low toxicity, biodistribution appropriate for the disease under study, absence of immunologic response and low cost. A novel approach to infection diagnosis is the use of radiolabelled antibiotics. Antibiotics localize in the infectious focus, where they are frequently taken up and metabolized by microorganisms. The majority of the various antibiotics studied so far are those of the quinolones group (ciprofloxacin, sparfloxacin, enrofloxacin, levofloxacin, norfloxacin and ofloxacin). More recently, the labeling of ceftizoxime, a semisynthetic third generation cephalosporin, has been reported. The relevant features of labeled antibiotics in research and/or clinical infection diagnosis are the focus of this article.
Unusually High Prevalence of Panton-Valentine Leukocidin Genes among Methicillin-Sensitive Staphylococcus aureus Strains Carried in the Indonesian Population

ABSTRACT Few data on the molecular characteristics and epidemiology of Staphylococcus aureus from Indonesia are available. The purpose of the present study was to define S. aureus reservoirs in both the Indonesian community and hospital using a collection of 329 nasal carriage isolates obtained during a survey of 3,995 healthy individuals and patients from Java, Indonesia. Only one strain (0.3%) was identified as methicillin-resistant S. aureus by mecA gene PCR. The Panton-Valentine leukocidin (PVL) genes were detected in 35 methicillin-sensitive S. aureus strains (10.6%). Molecular typing by pulsed-field gel electrophoresis of the 329 isolates showed extensive genetic diversity among both PVL-positive and PVL-negative strains. In Surabaya, Indonesia, however, a cluster was identified that was strongly associated with the presence of the PVL locus (P < 0.0001). As determined by high-throughput amplified fragment length polymorphism, PVL-positive strains occurred throughout all major AFLP clusters (I to IV). Multilocus sequence typing of a subset of isolates showed that most PVL-positive strains belonged to sequence type (ST) 188, while most PVL-negative isolates belonged to ST45. The high prevalence of PVL-positive S. aureus strains in certain regions of Indonesia is of concern since these strains may cause severe infections in the community and in hospitals.
Plasma glucose kinetics during exercise in subjects with high and low lactate thresholds.

The purpose of this study was to test the hypothesis that the rate of plasma glucose oxidation during exercise is inversely related to muscle respiratory capacity. To this end, 14 subjects were studied: in 7 of these subjects, the blood lactate threshold (LT) occurred at a relatively high intensity [i.e., at 65 +/- 2% of peak cycle ergometer oxygen uptake (VO2 peak)], whereas in the other 7 subjects, LT occurred at a relatively low intensity (i.e., at 45 +/- 2% of VO2 peak). VO2peak did not differ between the two groups, but citrate synthase activity in the vastus lateralis muscle was 53% higher (P < 0.05) in the high LT group. A primed continuous infusion of [U-13C]glucose was used to quantify rates of glucose appearance (Ra), disappearance (Rd), and oxidation (R(ox)) during 90 min of exercise at 55% VO2peak. Although both absolute and relative rates of oxygen uptake during exercise were similar in the two groups, mean Ra and Rd were 17% lower (P < 0.001) in the high LT group, and mean R(ox) was 25% lower (21.0 +/- 2.6 vs. 27.9 +/- 2.6 mumol.min-1.kg-1; P < 0.001). The percentage of total energy derived from glucose oxidation was inversely related to muscle citrate synthase activity (r = -0.85; P < 0.01). These data support the concept that skeletal muscle respiratory capacity has a major role in determining the metabolic response to submaximal exercise.
No Evidence of Sleep Apnea in Children with Attention Deficit Hyperactivity Disorder

Children with attention deficit hyperactivity disorder (ADHD) may have a component of sleep apnea causing arousal and contributing to ADHD behavior during the day. Twenty non-ADHD children between 4 and 16 years of age were compared with 18 children with ADHD with use of nocturnal polysomnography (PSG) and psychometric tests. The psychometric testing confirmed that the control group were normal and that the ADHD children fulfilled the diagnostic criteria for ADHD. The PSG showed normal arousal indexes for the ADHD group (9.8 ± 3.9/hr) and controls (10.2 ± 3.1/hr), and normal apnea/hypnea indexes for the ADHD group (1.0 ± 2.4/hr) and controls (0.6 ± 0.9/hr). The sleep architecture was not significantly different between groups. There were no sleep abnormalities in the ADHD children that could be responsible for, or contributing to, the disorder.
ACTION OF THE NEUROTOXIN KAINIC ACID ON HIGH AFFINITY UPTAKE OF l‐GLUTAMIC ACID IN RAT BRAIN SLICES

Kainic acid is a linear competitive inhibitor (Kis 250 μm) of the ‘high affinity’ uptake of l‐glutamic acid into rat brain slices. Kainic acid inhibits the ‘high affinity’ uptake of l‐glutamic, d‐aspartic and l‐aspartic acids to a similar extent. Kainic acid is not actively taken up into rat brain slices and is thus not a substrate for the ‘high affinity’ acidic amino acid transport system or any other transport system in rat brain slices. Kainic acid (300 μm) does not influence the steady‐state release or potassium‐stimulated release of preloaded d‐aspartic acid from rat brain slices.
The validity of a parent report instrument of child language at twenty months

ABSTRACT When carefully assessed and analysed, parent report can provide a valuable overall evaluation of children's language at 20 months. Norming information and validity coefficients are presented here for a vocabulary checklist assessment included in the Early Language Inventory. Normative data are provided for fullterm, preterm, and precocious samples, including selected vocabulatory subsets that are indicative of early language learning style. The vocabulary checklist has substantial validity as indexed by correlations with the Bayley Scales of Infant Development and particularly with a language subscale derived from that test.
Cloning, DNA sequencing, and characterization of a nifD-homologous gene from the archaeon Methanosarcina barkeri 227 which resembles nifD1 from the eubacterium Clostridium pasteurianum

L. Sibold, M. Henriquet, O. Possot, and J.-P. Aubert (Res. Microbiol. 142:5-12, 1991) cloned and sequenced two nifH-homologous open reading frames (ORFs) from Methanosarcina barkeri 227. Phylogenetic analysis of the deduced amino acid sequences of the nifH ORFs from M. barkeri showed that nifH1 clusters with nifH genes from alternative nitrogenases, while nifH2 clusters with nifH1 from the gram-positive eubacterium Clostridium pasteurianum. The N-terminal sequence of the purified nitrogenase component 2 (the nifH gene product) from M. barkeri was identical with that predicted for nifH2, and dot blot analysis of RNA transcripts indicated that nifH2 (and nifDK2) was expressed in M. barkeri when grown diazotrophically in Mo-containing medium. To obtain nifD2 from M. barkeri, a 4.7-kbp BamHI fragment of M. barkeri DNA was cloned which contained at least five ORFs, including nifH2, ORF105, and ORF125 (previously described by Sibold et al.), as well as nifD2 and part of nifK2. ORFnifD2 is 1,596 bp long and encodes 532 amino acid residues, while the nifK2 fragment is 135 bp long. The deduced amino acid sequences for nifD2 and the nifK2 fragment from M. barkeri cluster most closely with the corresponding nifDK1 gene products from C. pasteurianum. The predicted M. barkeri nifD2 product contains a 50-amino acid insert near the C terminus which has previously been found only in the clostridial nifD1 product. Previous biochemical and sequencing evidence indicates that the C. pasteurianum nitrogenase is the most divergent of known eubacterial Mo-nitrogenases, most likely representing a distinct nif gene family, which now also contains M. barkeri as a member. The similarity between the methanogen and clostridial nif sequences is especially intriguing in light of the recent findings of sequence similarities between gene products from archaea and from low-G+C gram-positive eubacteria for glutamate dehydrogenase, glutamine synthetase I, and heat shock protein 70. It is not clear whether this similarity is due to horizontal gene transfer or to the resemblance of the M. barkeri and C. pasteurianum nitrogenase sequences to an ancestral nitrogenase.
Excitotoxic Death of a Subset of Embryonic Rat Motor Neurons In Vitro

Abstract : We have used cultures of purified embryonic rat spinal cord motor neurons to study the neurotoxic effects of prolonged ionotropic glutamate receptor activation. NMDA and non‐NMDA glutamate receptor agonists kill a maximum of 40% of the motor neurons in a concentration‐ and time‐dependent manner, which can be blocked by receptor subtype‐specific antagonists. subunit‐specific antibodies stain all of the motor neurons with approximately the same intensity and for the same repertoire of subunits, suggesting that the survival of the nonvulnerable population is unlikely to be due to the lack of glutamate receptor expression. Extracellular Ca2+ is required for excitotoxicity, and the route of entry initiated by activation of non‐NMDA, but not NMDA, receptors is L‐type Ca2+ channels. Ca2+ imaging of motor neurons after application of specific glutamate receptor agonists reveals a sustained rise in intracellular Ca2+ that is present to a similar degree in most motor neurons, and can be blocked by appropriate receptor/channel antagonists. Although the lethal effects of glutamate receptor agonists are seen in only a subset of cultured motor neurons, the basis of this selectivity is unlikely to be simply the glutamate receptor phenotype or the level/pattern of rise in agonist‐evoked intracellular Ca2+.
Factors Affecting the Adoption of an Internet-based Sales Presence for Small Business

The Internet has doubled in size every year in recent years and now spans the globe, facilitating the exchange of all matter of digital data. Recent development has been categorized by an explosion in new commercial activity. Despite overwhelming coverage in the popular press, relatively little is understood regarding the impact the Internet is having on firms that use this medium to facilitate commerce. Even less is understood about the impact on small enterprises-the largest segment of U.S., Japanese, and Western European businesses. This article reports the results of an exploratory study examining critical issues surrounding the use of the Internet in emerging enterprises. The survey (1) describes how small businesses develop and use their on-line sales presence, (2) explores factors that motivate firms to invest in electronic commerce, (3) assesses the importance of the expected benefits of an on-line sales presence on the decision to go on-line, and (4) examines some of the barriers that prevent sma.
Evaluation of Cultural Practices for Potential to Control Strawberry Sap Beetle (Coleoptera: Nitidulidae)

Abstract Strawberry sap beetle, Stelidota geminata (Say) (Coleoptera: Nitidulidae), adults and larvae feed on and contaminate marketable strawberry (Fragaria L.) fruit. The beetle is a serious pest in the northeastern United States, with growers in multiple states reporting closing fields for picking prematurely due to fruit damage. Three options were evaluated for potential to reduce strawberry sap beetle populations. First, the influence of plant structure on accessibility of fruit in different strawberry cultivars to strawberry sap beetle was assessed by modifying plant structure and exposing caged plants to strawberry sap beetle adults. Severity of damage to berries staked up off the ground was similar to damage to those fruit contacting the soil, showing that adults will damage fruit held off the ground. Second, baited traps were placed at three distances into strawberry fields to determine whether overwintered beetles enter strawberry fields gradually. Adult beetles were first caught in the strawberries ≈19 d after occurring in traps placed along edges of adjacent wooded areas. The beetles arrived during the same sampling interval in traps at all distances into the fields, indicating that a border spray is unlikely to adequately control strawberry sap beetle. Third, the number of strawberry sap beetle emerging from strawberry for 5 wk after tilling and narrowing of plant rows was compared in plots renovated immediately at the end of harvest and in plots where renovation was delayed by 1 wk. In the 2-yr study, year and not treatment was the primary factor affecting the total number of emerging strawberry sap beetle. Overall, limited potential exists to reduce strawberry sap beetle populations by choosing cultivars with a particular plant structure, applying insecticide as a border spray, or modifying time of field renovation.
Availability of Corona Cage for Predicting Audible Noise Generated from HVDC Transmission Line

The authors examine the feasibility of using a corona cage to predict audible noise (AN) generated from an HVDC (high-voltage direct current) transmission line. The possible use of the cage is based on the assumption that generation quantities of AN and corona current are determined by F/sub max/ (the 'true' maximum conductor surface gradient in the presence of space charge) regardless of the surrounding electrode arrangement. This assumption has been verified by tests using corona cages and a test line. The results indicate that a corona cage is indeed suitable for predicting AN generated from HVDC transmission lines. It is applicable to DC lines with any line configuration and any polarity arrangement. >
Open versus laparoscopic radical prostatectomy: Part II

notably the nodes were withdrawn in a protective bag [7]. In the largest series of node dissection in node-positive patients there were no cases of peritoneal, parietal or trocar port seeding, even in hormone-resistant patients [8]. Although the follow-up is short, prostate cancer does not appear to implant readily on the peritoneum or trocar track. The laparoscopic extraperitoneal approach avoids this potential risk of intraperitoneal dissemination [9–12].
Clinical characteristics of cancer patients referred early to supportive and palliative care.

BACKGROUND Palliative care is evolving from end-of-life care to care provided earlier in the disease trajectory. We compared clinical characteristics between patients referred late in the course of their disease (late referrals, LRs) with patients referred earlier (early referrals, ERs). METHOD Six hundred and ninety-five patients referred to the Supportive Care Center (SCC) with follow-up within 30 days were enrolled. One hundred ERs (expected survival ≥ 2 years or receiving treatment for curative intent, 14.4%) were compared with a random sample of 100/595 consecutive LRs (all others). RESULTS ERs were younger (54.4 versus 59.5, p=0.009), more likely to have head and neck cancer (67% versus 6%, p<0.0001), alcoholism (15% versus 4%, p=0.014), and shorter disease duration until first palliative care consultation (3.8 months versus 16.2 months, p<0.0001). They were also more likely to be referred by radiation oncologists (49% versus 3%, p<0.0001), be referred for treatment-related side effects (70% versus 9%, p<0.0001), and receive more anticancer treatment (74% versus 48%, p=0.0002). Head and neck cancer and reason for referral were independent predictors for ERs (p<0.0001) in multivariate analysis. Baseline Edmonton Symptom Assessment System (ESAS) symptoms were similar between ERs and LRs. Both groups exhibited improved ESAS scores at follow-up; LRs experienced greater improvement in the symptom distress score (-5.5 versus -3, p=0.007). The median total number of medical visits was higher in ERs (p<0.001); however, the median number of visits per month was higher in LRs (p<0.001). CONCLUSIONS ERs had different patient characteristics than LRs, and although ERs experience distress similar to that of LRs, their needs and outcomes differ.
The Hyaluronic Acid Receptor CD44 Coordinates Normal and Metaplastic Gastric Epithelial Progenitor Cell Proliferation*

Background: Gastric parietal cell atrophy causes metaplasia, reactive stem cell proliferation, and increased risk for cancer. Results: Atrophy induces proliferation of CD44-positive epithelial cells that requires ERK → CD44 → STAT3 signaling. Conclusion: CD44 is a putative gastric stem cell marker that regulates normal and metaplasia-associated proliferation. Significance: Targeted pharmacological inhibition of ERK/CD44/STAT3 signaling may help block or reverse proliferation in precancerous atrophic/metaplastic lesions. The stem cell in the isthmus of gastric units continually replenishes the epithelium. Atrophy of acid-secreting parietal cells (PCs) frequently occurs during infection with Helicobacter pylori, predisposing patients to cancer. Atrophy causes increased proliferation of stem cells, yet little is known about how this process is regulated. Here we show that CD44 labels a population of small, undifferentiated cells in the gastric unit isthmus where stem cells are known to reside. Loss of CD44 in vivo results in decreased proliferation of the gastric epithelium. When we induce PC atrophy by Helicobacter infection or tamoxifen treatment, this CD44+ population expands from the isthmus toward the base of the unit. CD44 blockade during PC atrophy abrogates the expansion. We find that CD44 binds STAT3, and inhibition of either CD44 or STAT3 signaling causes decreased proliferation. Atrophy-induced CD44 expansion depends on pERK, which labels isthmal cells in mice and humans. Our studies delineate an in vivo signaling pathway, ERK → CD44 → STAT3, that regulates normal and atrophy-induced gastric stem/progenitor-cell proliferation. We further show that we can intervene pharmacologically at each signaling step in vivo to modulate proliferation.
