Factors Affecting the Utilization of Specialty and General Medical Mental Health Services

This study compares the extent to which need, predisposing, and enabling factors affect the use of mental health services in the specialty and general medical health sectors during a 6-month period. Data are drawn from the first wave of interviews of the Epidemiological Catchment Area (ECA) project at the Yale University site. The results indicate that 1) in the general population, factors affecting use of the two sectors differ; 2) among those using any mental health services, factors affecting use of the two sectors differ; 3) indicators of need have the strongest relationships with utilization; and 4) the effects of predisposing and enabling factors are contingent upon the presence of need.
Web use and peer interconnectivity metrics for academic web sites

This paper introduces two new web link count metrics to complement the existing Web Impact Factor. The first is provisionally cast as an indicator of the average degree of online informal scholarly communication and information use by the academics in a given university. The second has a similar construction but focuses on the degree of web interconnection in terms of both inlinks and outlinks. The latter metric is based upon a more elaborate mechanism than raw link counts: totalling the minimum number of links between universities over all distinct pairs in the chosen set that include the given institution. Statistical tests give evidence that the results of both correlate with institutional research productivity in the UK, providing preliminary support for their continued development. Further research is needed into causes of linking in order to allow more meaningful interpretations of their values to be made.
Biogenic amines and narcotic effects. II. Serotonin turnover in the rat after acute and chronic morphine administration.

As determined by nonisotopic and isotopic techniques, the turnover of cerebral serotonin (5-HT) is enhanced in Sprague-Dawley rats after a single injection of 16 or 32 mg/kg of morphine. Low and intermediate doses of morphine ( e.g. , 4 and 8 mg/kg) fail to alter whole-brain 5-HT metabolism. Chronic administration of 16 mg/kg of morphine results in the development of tolerance to the increase in 5-HT turnover observed afer a single injection. Naloxone pretreatment blocks the increase in 5-HT turnover induced by 16 mg/kg of morphine. Wistar rats showed a similar increase in 5-HT turnover after 16 mg/kg of morphine. The increase in 5-HT turnover after acute morphine administration was not reflected by an increase in in vitro tryptophan hydroxylase activity. Moreover, tryptophan hydroxylase activity was not altered by chronic morphine treatment. These observations suggest that 5-HT synthesis is stimulated by acute morphine administration and tolerance develops to this effect with repeated exposure to the drug. The possible significance of these data are discussed in relation to the role of 5-HT in narcotic-induced motor effects.
Simultaneous registration and clustering for temporal segmentation of facial gestures from video

Ethanol and/or acetaldehyde are produced by reacting at elevated temperature and pressure methanol with synthesis gas in the presence of a catalyst comprising a metal complex in which the metal is a metal of Group VIII of the Periodic Table other than iron, palladium and platinum and the ligand is derived from cyclopentadiene or a substituted cyclopentadiene and a promoter which is an iodide or a bromide. Optionally there is also added as a co-promoter a compound of formula X(A) (B) (C) wherein X is nitrogen, phosphorus, arsenic, antimony or bismuth and A, B and C are individually C1 to C20 monovalent hydrocarbyl groups which are free from aliphatic carbon-carbon unsaturation and are bound to the X atom by a carbon/X bond, or X is phosphorus, arsenic, antimony or bismuth and any two of A, B and C together form an organic divalent cyclic ring system bonded to the X atom, or X is nitrogen and all of A, B and C together form an organic trivalent cyclic ring system bonded to the X atom, e.g. triphenylphosphine.
TactoGlove: Displaying Tactile Sensations in Tacto-gestural Interaction

In the research field of augmented reality, many experimental systems have been introduced so far to provide natural interactions with a virtual character and a surrounded environment. To introduce a high level interaction, not only visual and auditory information but also other human sensations such as tactile sensations and somatosensory information should be presented to a user. In this study, we pay attention to the tactile sensation in the manipulation of a virtual character, and develop TactoGlove for presenting tactile sensations to a user. The virtual environment is manipulated by intuitive gestures, and tactile sensations corresponding with the gestural actions are presented to the user through TactoGove to establish multimodal interactions. Four subjects tried the system, and significant evaluations were obtained in the interaction between a virtual character and a user.
Surgical Options in Rheumatic Mitral Valve Disease in Children

In children with rheumatic heart disease, conservative valve surgery is the best option whenever feasible. Surgeons must develop an attitude and interest in valve repair techniques that can be easily learned. Patients who undergo valve repair at an early age are at risk of requiring additional surgery over time. Mechanical valve replacement, nonetheless, should be reserved for situations where more conservative approaches are not feasible.
Evaluation of morbillivirus exposure in cetaceans from the northern Gulf of Mexico 2010-2014

*Corresponding author: Deborah.Fauquier@noaa.gov ABSTRACT: The potential role of morbillivirus was evaluated in the deaths of >1100 bottlenose dolphins Tursiops truncatus and other small cetaceans that stranded from February 2010 through July 2014, during the northern Gulf of Mexico (GoM) unusual mortality event (UME). Morbillivirus analysis was carried out on 142 live or freshly dead cetaceans and results were combined with samples from 102 live, free-ranging bottlenose dolphins sampled during capture-release health assessments conducted from 2011 to 2014. Polymerase chain reaction (PCR) testing for morbillivirus showed that 9.9% (14/142) of the stranded cetaceans and 1% (1/83) of the free-ranging live dolphins were positive for dolphin morbilliviral (DMV) RNA. In contrast, previous DMV dolphin die-offs had DMV detectable by PCR in 61 to 97% of animals tested. Histologic findings consistent with morbillivirus infection, including lymphoid depletion, bronchointerstitial pneumonia, syncytial cell formation, or meningoencephalitis, were found in 6.6% (9/136) of the cetaceans that underwent histologic examinations. Serological analysis using a virus neutralization assay found that 29% (5/17) of live stranded and 23% (23/102) of live free-ranging bottlenose dolphins had titers of 64 or greater for cetacean morbillivirus, indicating prior but not necessarily recent exposure to morbillivirus. Current findings suggest that DMV infection, although present in the northern GoM, was sporadic and occurred at low levels and therefore was not the primary cause of the northern GoM UME. Confirmation of DMV infections and existing DMV titers demonstrate continued exposure to morbillivirus among northern GoM cetaceans since the first detection of this virus in the early 1990s.
Physiology and taxonomy of Thiobacillus strain TJ330, which oxidizes carbon disulphide (CS2)

A bacterium (strain TJ330) capable of using carbon disulphide (CS2) as its sole energy source in an acidic environment was isolated from a peat biofilter used in experiments to remove CS2 and hydrogen sulphide (H2S) from air. Its physiology and taxonomy are described here. The strain oxidized CS2, H2S and elemental sulphur to sulphate chemolithotrophically. The rate of sulphate production was highest at pH 2. The maximum growth rate constant (µmax) using CS2 as a substrate was 3·9 × 10−2 h−1 (generation time 18 h) and the Monod constant (Ks) was 0·97–2·6 µmol l−1 CS2 (74–198 µg l−1), corresponding to an equilibrium with 15–40 ppm CS2 in the headspace. The optimum growth temperature using elemental sulphur as a substrate was 28 °C. The strain bears morphological and physiological similarities to Thiobacillus thiooxidans, but the latter is incapable of oxidizing CS2. The strain TJ330 (DSM 8985) showed only 44·2 + 11·8% DNA homology with the type strain T. thiooxidans ATCC 19377, while its homology with T. ferrooxidans ATCC 23270 was 17·1 + 3·4%. The strain TJ 330 represents a high‐affinity bacterium which can effectively remove low CS2 concentrations in an acid environment. These properties can be utilized in biotechnological purification applications.
Stringlish: improved English string searching in binary files

When analyzing binary files, printable strings are easy to find, but a naïve approach yields a large number of false positives: ‘uninteresting’ string‐like sequences that occur by chance in the binary. We present a lightweight yet surprisingly effective method of filtering printable strings for English or English‐like sequences. Copyright © 2015 John Wiley & Sons Ltd.
Kinetic modeling of PET data without blood sampling

In positron emission tomography (PET) imaging, application of kinetic modeling always requires an input curve (IC) together with the PET data. The IC can be obtained by means of external blood sampling or, in the case of cardiac studies, by means of a region-of-interest (ROI) drawn on the blood pool. It is, however, very unsuitable to withdraw and to analyze blood samples, and in small animals, these operations become difficult, while ICs determined from ROIs are generally contaminated by emissions from neighboring sites, or they are underestimated because of partial volume effect. In this paper, we report a new method to extract kinetic parameters from dynamic PET studies without a priori knowledge of the IC. The method is applied in human brain data measured with fluorodeoxyglucose (FDG) human-brain and in cardiac-rat perfusion studies with /sup 13/N-ammonia and /sup 11/C-acetate. The tissue blood volume (TBV), usually fitted together with the rate constants, is extracted simultaneously with the tissue time activity curves for cardiac studies, while for brain gray matter, TBV is known to be about 4% to 7%. The shape of IC is obtained by means of factor analysis from an ROI drawn around a cardiac tissue or a brain artery. The results show a good correlation (p<0.05) between the cerebral metabolic rate of glucose, myocardial blood flow, and oxygen consumption obtained with the new method in comparison to the usual method. In conclusion, it is possible to apply kinetic modeling without any blood sampling, which significantly simplifies PET acquisition and data analysis.
Modulation classification in alpha-stable noise

In this paper, we propose a modulation classifier for non-Gaussian noise environment. The modulation model is formed via autoregressive spectrum modeling, where the additive noise is assumed to obey symmetric alpha-stable distribution. The modulation model used the instantaneous frequency and bandwidth parameters as obtained from the roots of the autoregressive polynomial. The distinguish features are extracted based on fractional lower order moments of alpha-stable distribution random variable. Computer simulations demonstrate its efficiency and comparison with other methods is also given.

Pre-operative grading of intracranial glioma.

AIM To compare the accuracy of MR-determined cerebral blood volume (CBV) maps with SPECT imaging with thallium-201 in pre-operative grading of intracranial glioma. MATERIAL AND METHODS Nineteen patients (7 female and 12 male, mean age 46.8 years) with intracranial gliomas were examined with MR perfusion imaging pre-operatively. Sixteen of these patients were also examined with SPECT imaging with thallium-201. The tumour to contralateral white matter NI (negative integral) and tracer uptake ratios were evaluated. The ratios in high-grade and low-grade tumours were compared. RESULTS The maximum CBV ratios of grades I and II gliomas (2.958+/-2.217) were significantly lower than the maximum CBV ratio of grades III and IV (9.484+/-4.520), p<0.001. There was no statistical difference when CBV ratios of grades I and II (p=0.381), grades II and III (p=0.229) and grades III and IV (p=0.476) gliomas were compared. Thallium SPECT imaging showed no difference in tumour uptake ratio between low-grade and high-grade gliomas (p=0.299). CONCLUSION MR-determined NI was useful for pre-operative grading of intracranial gliomas but SPECT thallium-201 imaging was not.
A comparative study of the migration behaviors of cellulose particles in natural ester and mineral oil under DC electrical field

Natural ester is considered to be a suitable substitute of mineral oil in transformer. Previously the bridging phenomenon in mineral oil has been studied. Due to the difference in physicochemical and dielectric properties between mineral oil and natural ester, the bridging phenomenon is also disparate. The migration behaviors of pressboard particle in contaminated mineral oil and natural ester under the influence of DC electric field has been investigated respectively in this paper. The formation of cellulose bridge is observed between two plate electrodes under DC electric field of three different intensities. Images during the bridging process were captured. Through the comparative study of the bridges formation and the stable conduction current, a conclusion can be draw that natural ester has a better performance than mineral when it comes to the bridging phenomena of the particles.

Two New Zealand outbreaks of norovirus gastroenteritis linked to commercially farmed oysters.

AIM We report on the investigations of two gastroenteritis outbreaks, which were linked to a common source. METHODS Retrospective cohort studies were conducted for two gastroenteritis outbreaks which occurred in Auckland and in Waikato. Faecal samples and samples of oyster meat were analysed. Environmental surveys of implicated areas were conducted. RESULTS 10 out of 16 people who had eaten at a catered event in Auckland, and 3 out of 15 people who had eaten at a Waikato restaurant, experienced gastroenteritis. The symptoms, duration of illness and incubation periods were consistent with norovirus gastroenteritis in both outbreaks. The consumption of oysters was strongly associated with an increased risk of illness. Faecal samples were positive for norovirus. Oysters from both outbreaks were traced back to the same growing area. Samples of oyster meat from one of the restaurants and from the growing area were positive for norovirus. The growing area was closed for further investigation. A pipe from a waste water treatment plant was later found to be leaking partially treated effluent into a stream discharging near the implicated growing area. CONCLUSION Investigation of these two outbreaks led to the discovery of a common source of norovirus at a commercial oyster growing area.
Effets de la modulation de la masse grasse sur la production d'adiponectine chez la souris : conséquences sur le métabolisme hépatique des lipides

L’adiponectine (ApN) est une adipokine de 30 KDa produite abondamment par le tissu adipeux qui a ete decrite pour la premiere fois en 1995. Des lors qu’une correlation inverse entre les taux circulants d’ApN et l’adiposite a ete mise en evidence, de tres nombreuses etudes ont ete initiees pour chercher a etablir un lien avec les pathologies liees au syndrome metabolique. Ainsi, chez les patients obeses et diabetiques, une perte de poids induite par un traitement medicamenteux ou un regime hypocalorique s’accompagne d’une augmentation des taux circulants d’ApN et d’une amelioration des parametres biochimiques. Il ressort de ces etudes que des taux eleves d’ApN sont correles a une amelioration de la sensibilite a l’insuline, des parametres lipidiques et une diminution du risque cardiovasculaire. Cependant, les mecanismes d’action conduisant a l’amelioration du metabolisme lipidique et glucidique restent encore mal connus. Au cours de cette etude, nous avons, dans un premier temps, cherche a determiner les consequences d’une variation de la masse grasse sur la production de l’ApN chez la souris. Pour cela, differentes strategies nutritionnelles et pharmacologiques, conduisant a une fonte ou a une augmentation de la masse grasse, ont utilisees. Les resultats obtenus suggerent que la production d’ApN n’est pas dependante de la taille des adipocytes mais plutot de leur etat inflammatoire. Dans un second temps, grâce a un modele d’explants de foie en culture, nous avons cherche a determiner les effets directs de l’ApN sur le metabolisme lipidique du foie. Une premiere approche a consiste a tester les effets a long terme c’est a dire susceptibles de correspondre a des modifications d’expression genique et de synthese proteique en incubant les explants pendant 21h dans un milieu de culture contenant de l’ApN en presence ou non d’insuline. Les resultats suggerent que l’ApN accentue les effets de l’insuline, ce qui se traduit par une meilleure utilisation du glucose avec en contre partie une stimulation de la lipogenese et une reduction de la s-oxydation en presence d’insuline. De plus, l’ApN apparait exercer un effet sur les voies de catabolisme des HDL. Par une seconde approche, nous avons teste les effets a court terme de l’ApN sur les capacites β-oxydatives en traitant les explants pendant 45 min. Dans ces conditions plus appropriees pour mettre en evidence l’activation des voies de regulation rapides, la presence d’ApN entraine une stimulation de la s-oxydation qui s’accompagne d’une augmentation de la p- AMPK. En conclusion, ces resultats suggerent que l’ApN exerce des effets directs sur le metabolisme hepatique du glucose compatible avec l’effet insulino-sensibilisateur observe in vivo. En revanche, les resultats ne permettent pas, a ce stade, d’etablir une relation entre une induction par l’ApN de l’activite s-oxydative des acides gras dans le foie et ces effets benefiques sur les parametres lipidiques.
Estimated additional lifetime risk of cancer attributable to diagnostic CT in a pediatric bone marrow transplant cohort: Experience at a single academic institution

Purpose: To determine the frequency of CT procedures in a cohort of bone marrow transplant patients and estimate the effective dose from each CT procedure as well as rough estimates of lifetime attributable risk (LAR) of cancer (both incidence and mortality). Background: Pediatric patients who undergo bone marrow transplant benefit greatly from the diagnostic power of computed tomography, but due to the need for frequent imaging, these patients are repeatedly exposed to the carcinogenic potential of ionizing radiation. Methods: CT Imaging and patient parameters were collected from a retrospective cohort of bone marrow transplant patients. Dosimetry was estimated as a function of age, dose length product (DLP), and scan region based on published DLP to effective dose tables. Lifetime attributable risk (LAR) of cancer as a function of age, gender, and organ specific dose was derived from BEIR VII phase 2 estimates. Results: 44 patients with bone marrow transplant were included and ranged in age from 7 months to 20 years (average age, 9 years). The average number of CT studies per patient was 3.2 over the 15 month period. The average effective dose for each study was 5.9 +/– 4.5 mSv. Cumulative effective dose to each patient was 20 +/– 32 mSv. It was estimated that in this cohort, the CT imaging performed over a 15-month period on a 64-slice scanner led to a lifetime additional risk of cancer incidence of 5 in 1000 and a lifetime additional risk of cancer mortality of 2 in 1000. Conclusion: Diagnostic CT is important in the assessment and management of ill patients following bone marrow transplant. The risk of ionizing radiation leading to additional development of cancer merits using as low a CT technique as reasonable to achieve a diagnostic study.
Cytokine Expression in Pediatric Helicobacter pylori Infection

ABSTRACT Helicobacter pylori infection is one of the most common gastrointestinal infections worldwide and almost invariably causes chronic gastritis in the infected host. A predominant Th1 profile has been demonstrated in H. pylori-infected mucosa from adults, but no previous study has evaluated in situ cytokine expression in children. We therefore examined expression of proinflammatory, anti-inflammatory, and regulatory cytokines by immunohistochemistry in cryopreserved antral biopsy specimens from 10 H. pylori-infected and 10 uninfected children and correlated expression of cytokines with histology scores. Concomitant expression of interleukin-8 (IL-8), gamma interferon (IFN-γ), IL-4, transforming growth factor β, and tumor necrosis factor alpha was seen in 8/10 H. pylori-infected cases and in 5/10 noninfected cases; all H. pylori-infected subjects showed staining for at least two of the cytokines. The proportion of epithelial cytokine-specific staining did not differ significantly between the groups, either in surface or glandular epithelium. Furthermore, no significant differences were noticed between intraepithelial or lamina propria lymphocyte staining in the groups. There was, however, a tendency of higher numbers of IFN-γ- and IL-8-positive cells in the H. pylori-infected group. IFN-γ and IL-8 lamina propria lymphocyte expression correlated significantly with antrum chronic inflammation, but there was no correlation between histology scores and epithelial cytokine expression. When the same techniques were used, the cytokine response appeared to be smaller in H. pylori-infected children than in adults, and there was no clear Th1 dominance. These results therefore suggest a different mucosal immunopathology in children. It remains to be determined whether the gastric immune response is downregulated in children with H. pylori infection and whether this is relevant to the outcome of infection.
Sub-synchronous interaction analysis between DFIG based wind farm and series compensated network

This paper analyzes the sub-synchronous interaction (SSI) phenomenon between the doubly fed induction generator (DFIG) based wind farm (WF) and the series capacitor compensated network. The possible types of SSI in the DFIG based WF are studied. The factors influencing the SSI of DFIG based WF are investigated. The large signal stability and small signal stability of the DFIG based WF with different series compensation (SC) level and wind speed are simulated and compared.
