Abstract
Guidelines recommend that head-injured patients who require life-saving decompressive surgery should undergo surgery within 4 h. To assess the compliance with this recommendation 100 consecutive head-injured patients admitted to a regional neurosurgical unit (RNU) were studied. Time points from head injury to craniotomy were documented and analysed. Twenty-four patients underwent emergency craniotomy, only one being operated on within 4 h. In this cohort of patients there was no relationship between timing of surgery and outcome. In order to investigate whether it is possible to reduce delays in transportation time, theoretical models were created to determine whether direct transfer to the RNU would be faster by land or air ambulance.

Experimental measurement of the mechanical properties of carotid atherothrombotic plaque fibrous cap. J Biomech 2009; 42:1650-5. [PMID: 19464014 DOI: 10.1016/j.jbiomech.2009.04.025] [Citation(s) in RCA: 65] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2008] [Revised: 03/31/2009] [Accepted: 04/17/2009] [Indexed: 11/29/2022]
Abstract
Eleven carotid atherothrombotic plaque samples were harvested from patients. Three samples that were highly calcified were discarded, while eight yielded results. The elastic properties of the material were estimated by fitting the measured indentation response to finite element simulations. The methodology was refined and its accuracy quantified using a synthetic rubber. The neo-Hookean form of the material model gave a good fit to the measured response of the tissue. The inferred shear modulus mu was found to be in the range 7-100 kPa, with a median value of 11 kPa. A review of published materials data showed a wide range of material properties for human atherothrombotic tissue. The effects of anisotropy and time dependency in these published results were highlighted. The present measurements were comparable to the static radial compression tests of Lee et al, 1991 [Structure-dependent dynamic behaviour of fibrous caps from human atherosclerotic plaques. Circulation 83, 1764-1770].

Abstract
Spatial attention is oriented by social visual cues: targets appearing at cued (gazed-at) locations are detected more rapidly than those appearing at uncued locations. The current studies provide evidence that social gaze directs attention to auditory as well as visual targets at cued locations. For auditory target detection the effect lasted from 300 to 1,005 ms while for discrimination the effect was restricted to 600 ms. Improved performance at 600-ms stimulus onset asynchrony was observed across all experiments and may reflect an optimal processing window for social stimuli. In addition, the orienting of attention by gaze was impaired by the presentation of negative faces. These experiments further demonstrate the unique and cross-modal nature of social gaze cueing.

Abstract
BACKGROUND AND PURPOSE To prospectively evaluate differences in carotid plaque characteristics in symptomatic and asymptomatic patients using high resolution MRI. METHODS 20 symptomatic and 20 asymptomatic patients, with at least 50% carotid stenosis as determined by Doppler ultrasound, underwent preoperative in vivo multispectral MRI of the carotid arteries. Studies were analysed both qualitatively and quantitatively in a randomised manner by two experienced readers in consensus, blinded to clinical status, and plaques were classified according to the modified American Heart Association (AHA) criteria. RESULTS After exclusion of poor quality images, 109 MRI sections in 18 symptomatic and 19 asymptomatic patients were available for analysis. There were no significant differences in mean luminal stenosis severity (72.9% vs 67.6%; p = 0.09) or plaque burden (median plaque areas 50 mm(2) vs 50 mm(2); p = 0.858) between the symptomatic and asymptomatic groups. However, symptomatic lesions had a higher incidence of ruptured fibrous caps (36.5% vs 8.7%; p = 0.004), haemorrhage or thrombus (46.5% vs 14.0%; p<0.001), large necrotic lipid cores (63.8% vs 28.0%; p = 0.002) and complicated type VI AHA lesions (61.5% vs 28.1%; p = 0.001) compared with asymptomatic lesions. The MRI findings of plaque haemorrhage or thrombus had an odds ratio of 5.25 (95% CI 2.08 to 13.24) while thin or ruptured fibrous cap (as opposed to a thick fibrous cap) had an odds ratio of 7.94 (95% CI 2.93 to 21.51) for prediction of symptomatic clinical status. CONCLUSIONS There are significant differences in plaque characteristics between symptomatic and asymptomatic carotid atheroma and these can be detected in vivo by high resolution MRI.

Abstract
Streptomyces coelicolor is a representative of the group of soil-dwelling, filamentous bacteria responsible for producing most natural antibiotics used in human and veterinary medicine. Here we report the 8,667,507 base pair linear chromosome of this organism, containing the largest number of genes so far discovered in a bacterium. The 7,825 predicted genes include more than 20 clusters coding for known or predicted secondary metabolites. The genome contains an unprecedented proportion of regulatory genes, predominantly those likely to be involved in responses to external stimuli and stresses, and many duplicated gene sets that may represent 'tissue-specific' isoforms operating in different phases of colonial development, a unique situation for a bacterium. An ancient synteny was revealed between the central 'core' of the chromosome and the whole chromosome of pathogens Mycobacterium tuberculosis and Corynebacterium diphtheriae. The genome sequence will greatly increase our understanding of microbial life in the soil as well as aiding the generation of new drug candidates by genetic engineering.

Abstract
OBJECTIVE We examined the correlation between the basal triiodothyronine resin uptake (T3-RU) levels in depressed subjects and the response to anti-depressant treatment. METHOD We treated with fluoxetine 235 outpatients meeting DSM-IV criteria for major depression. We measured T3 resin uptake (T3-RU) levels before the onset of treatment. The 17-item Hamilton Rating Scale for Depression (Ham-D-17) was administered before, during and after the eight weeks of treatment to assess changes in depressive symptoms. RESULTS 16 patients (6.8 percent) had low T3-RU levels (range 16.5-21), and 7 patients (3.0 percent) had high T3-RU levels (range 36-38). No relationship was found between T3-RU levels and clinical improvement, defined as either total Ham-D-17 score change or Ham-D-17 score < or = 7 in the last 3 weeks of treatment, even after adjusting for baseline severity of depression. CONCLUSION Abnormal T3-RU levels are rather uncommon in outpatient depression and do not correlate with the response to antidepressant treatment or lack thereof.

Abstract
OBJECTIVE This study compares the effectiveness of the Chinese version of the Beck Depression Inventory (CBDI) and the Chinese Depression Inventory (CDI) in screening for depression among Chinese Americans. METHOD Five hundred and three Chinese-Americans in primary care were administered the CBDI and the CDI for depression screening. The results were compared with standard semistructured interview. RESULTS With empirically determined cutoff scores of the CBDI (> or =13) and the CDI (>/=16), both instruments have good sensitivity (0.78) and excellent specificity (0.91 and 0.93, respectively). The correlation between the total scores of the two instruments was high (0.785, P < 0.01). The areas under the Receiver Operating Characteristic (ROC) curve of the CBDI and the CDI were 0.94 and 0.95, respectively, and were not significantly different. CONCLUSION When administered by interviewers, the CBDI and the CDI have comparable effectiveness. Low participation among Chinese-Americans with self-report measures limits both scales as efficient depression screening instruments.

Abstract
We have sequenced and annotated the genome of fission yeast (Schizosaccharomyces pombe), which contains the smallest number of protein-coding genes yet recorded for a eukaryote: 4,824. The centromeres are between 35 and 110 kilobases (kb) and contain related repeats including a highly conserved 1.8-kb element. Regions upstream of genes are longer than in budding yeast (Saccharomyces cerevisiae), possibly reflecting more-extended control regions. Some 43% of the genes contain introns, of which there are 4,730. Fifty genes have significant similarity with human disease genes; half of these are cancer related. We identify highly conserved genes important for eukaryotic cell organization including those required for the cytoskeleton, compartmentation, cell-cycle control, proteolysis, protein phosphorylation and RNA splicing. These genes may have originated with the appearance of eukaryotic life. Few similarly conserved genes that are important for multicellular organization were identified, suggesting that the transition from prokaryotes to eukaryotes required more new genes than did the transition from unicellular to multicellular organization.

Abstract
OBJECTIVES To measure the concentrations of particles less than 100 nm diameter and of oxides of nitrogen generated by cooking with gas and electricity, to comment on possible hazards to health in poorly ventilated kitchens. METHODS Experiments with gas and electric rings, grills, and ovens were used to compare different cooking procedures. Nitrogen oxides (NO(x)) were measured by a chemiluminescent ML9841A NO(x) analyser. A TSI 3934 scanning mobility particle sizer was used to measure average number concentration and size distribution of aerosols in the size range 10-500 nm. RESULTS High concentrations of particles are generated by gas combustion, by frying, and by cooking of fatty foods. Electric rings and grills may also generate particles from their surfaces. In experiments where gas burning was the most important source of particles, most particles were in the size range 15-40 nm. When bacon was fried on the gas or electric rings the particles were of larger diameter, in the size range 50-100 nm. The smaller particles generated during experiments grew in size with time because of coagulation. Substantial concentrations of NO(X) were generated during cooking on gas; four rings for 15 minutes produced 5 minute peaks of about 1000 ppb nitrogen dioxide and about 2000 ppb nitric oxide. CONCLUSIONS Cooking in a poorly ventilated kitchen may give rise to potentially toxic concentrations of numbers of particles. Very high concentrations of oxides of nitrogen may also be generated by gas cooking, and with no extraction and poor ventilation, may reach concentrations at which adverse health effects may be expected. Although respiratory effects of exposure to NO(x) might be anticipated, recent epidemiology suggests that cardiac effects cannot be excluded, and further investigation of this is desirable.

Abstract
BACKGROUND Patients treated in community clinics, particularly those of minority status, may rely more heavily on primary care physicians (PCPs) for the diagnosis and management of depression. We wished to determine how PCPs in a community clinic setting initially manage patients newly diagnosed with major depression. METHODS 698 patients were screened for major depression by the Structural Clinical Interview for DSM-III-R in a community-based primary care health center. Forty outpatients (29 Hispanic) were found to suffer from major depression. A letter explaining positive findings was sent to the patients' PCPs. Medical record charts were reviewed 3 months later to determine the PCP's management following the diagnosis. RESULTS Of the 38 patients who remained in the study at 3 months, 20 (53%) received no intervention from the PCP by the end of 3 months after diagnosis, and of these, 14 were Hispanic. Five (13%) were prescribed an antidepressant by the PCP. Nine (24%) were referred to mental health services for medication, psychotherapy or combination treatment. Four (11%) were prescribed an antidepressant and then referred to mental health services. Differences between management of Hispanic and non-Hispanic patients were not statistically significant. CONCLUSIONS Independent screening by psychiatrists in primary care settings may not be adequate enough to ensure appropriate management of depression by PCPs. Possible explanations may include time constraints during primary care visits, patient and/or physician reticence, and insufficient education of PCPs about depression.

Abstract
OBJECTIVE To measure the effect of matter collected by a method that has a 50% efficiency for particles with an aerodynamic diameter of 10 microm (PM10), generated by gas and electric cooking, on A549 epithelial cells with and without nitrogen dioxide (NO2). METHOD Multiple indoor PM10 samples were collected on Teflon filters during the use of gas or electric cookers. Interleukin-8 (IL-8) concentrations were measured with a sandwich enzyme linked immunosorbent assay (ELISA) system. RESULTS Treatment of A549 cells with PM10 generated from gas cooking resulted in increased concentrations of IL-8 compared with untreated cells; particles from the electric cooker had no effect. NO2 did not alter the concentration of IL-8. CONCLUSION PM10 generated by gas cooking has the potential to cause proinflammatory effects in lung cells. This may have implications for susceptible people.

Abstract
Platelet count and mean platelet volume (MPV) were estimated in 349 normal pregnancies at various gestational stages, and in 30 cases of pre-eclampsia. A probability plot was constructed from these data using discriminant analysis of MPV versus platelet count for the pre-eclamptic versus normal pregnancies. The sensitivity for pre-eclampsia was 90% (27/30) and the specificity was 83.3%. This plot may be of use in confirming risk of pre-eclampsia.

Abstract
Anti-Ro (SS-A) antibodies are important diagnostic markers for primary Sjögren's syndrome and systemic lupus erythematosus, but their detection by indirect immunofluorescence (IF) in the diagnostic laboratory is hindered by the low cellular abundance of 60kDa Ro protein (Ro60). The approach we used to overcome this problem was to transfect and over-express the Ro60 gene into HEp-2 cells. In this study we have used a mixture of Ro60 transfectants and untransfected HEp-2 cells (HEp-Ro60) as a substrate for IF-antinuclear antibody (ANA) testing in a hospital laboratory. Screening of 240 routine serum specimens identified 14 Ro transfectant-positive sera which were confirmed by counterimmunoelectrophoresis (CIE); 3 of these sera were ANA-negative on untransfected cells and regular HEp-2. A comparison of HEp-Ro60 and regular HEp-2 showed strong concordance of the different ANA patterns between the 2 substrates. No increase in background staining was observed on the Ro transfectants when reacted with normal human sera. A comparison between HEp-Ro60 and CIE for 53 sera from patients with primary Sjögren's syndrome showed that HEp-Ro60 were a sensitive and specific substrate for detection of anti-Ro antibodies. Masking of positive Ro transfectants was observed rarely in sera containing multiple ANA specificities, but the Ro60 staining on these transfectants were unmasked at higher serum dilutions. We conclude that HEp-Ro60 are a suitable substrate for IF-ANA in the routine laboratory and that they have the additional advantage over regular HEp-2 slides of being able to detect anti-Ro in ANA-negative sera. HEp-RO60 are also a valuable confirmatory test for sera giving equivocal precipitin reactions or ELISA results.

Abstract
Nine automated, activated partial thromboplastin time (APTT) reagents were evaluated on an automated coagulometer, in comparison with a manual reagent. The study consisted of three separate stages: 1) to choose a reagent that had a working stability between 4 degrees C and 8 degrees C for seven days and heparin sensitivity between 0 and 0.8 iu/ml; ii) assessment of sensitivity to specific factor deficiencies, particularly factors VIII, IX, XI and XII using standardised plasma serially diluted with factor-deficient plasma; and iii) assessment of sensitivity to the presence of a lupus anticoagulant, from a known positive panel. Only one reagent fulfilled all the essential criteria as an acceptable replacement for the manual reagent.

Abstract
Eighteen horses affected by the idiopathic headshaker syndrome were studied in an owner assessed trial to test the efficacy of some prophylactic therapies. Riding the affected animal with a veil over the nostrils gave varying degrees of temporary relief in three of 10 horses. Local (intra-nasal) corticosteroid therapy was reported to be slightly effective in three of nine horses, but treatment with sodium cromoglycate, systemic corticosteroid, flunixin meglumine and an antihistamine were generally ineffective. Bilateral infraorbital neurectomy provided sustained relief in three of seven horses, but in one of these cases, a reaction at the neurectomy site necessitated another surgical procedure after six months. A fourth horse was reported to be slightly improved after neurectomy. A period of nasal irritation resulting in self-inflicted trauma was a common complication of this surgery.

Abstract
A retrospective analysis was performed on 48 cases of suspected neoplasia involving the equine external genitalia. Forty nine squamous cell carcinomata (SCC) and 23 squamous papillomata (SP) were identified. Two cases of epithelial hyperplasia and one case of habronemiasis were also recognised histopathologically. The glans penis was the most common site of tumour development accounting for 53 per cent of cases of SCC and 61 per cent of SP. The urethral diverticulum, urethral process or urethra was involved in 27.6 per cent (8/29) of cases of SCC. Twelve per cent (5/41) of cases of SCC were confirmed to have metastatic involvement of the local lymph nodes. Papillomata showing pre-malignant changes were identified in five cases. Seventy five per cent (36/48) of the animals presented were ponies. All were geldings, mean age 16.5 years. Penile amputation and urethrostomy, preputial ablation and proximal urethrostomy or local excision were used in the surgical management of these animals; three cases were inoperable and destroyed at presentation. Oedema, haemorrhage and stenosis of the urethrostomy site were encountered as post operative complications. Sixty six per cent (6/9) of animals with SCC of the glans penis (without urethral involvement), which had a known history over the follow up period, treated by penile amputation and urethrostomy survived for longer than 18 months. Similarly, of those with urethral involvement only 28.6 per cent (2/7) survived for a similar follow-up period. SCC not uncommonly affects the external genitalia of aged pony geldings and frequently the glans penis. If the lesion is identified before local metastasis occurs, penile amputation and urethrostomy is indicated and the prognosis is favourable.

Abstract
OBJECTIVE To determine whether admitting elderly patients to hospital to give temporary relief to their carers is associated with increased mortality. DESIGN Prospective multicentre study comparing the mortality of patients admitted on a one off or rotational basis with that experienced while they were awaiting admission. SETTING A wide range of urban and rural district general, geriatric or long stay, and general practitioner hospitals. PATIENTS 474 Patients aged 70 or over who had 601 admissions. MAIN OUTCOME MEASURE Death. RESULTS 16 (3.4%) Of the 474 patients (2.7% of all 601 admissions) died while in hospital during an average stay of 15.7 days whereas 23 (4.9%) patients died while awaiting admission (average waiting time was 34.2 days). The 16 deaths in hospital and the 23 deaths during the longer waiting period correspond to death rates of 19.9 and 12.5 per 10,000 person days respectively. The difference between these of 7.4 is not statistically significant (95% confidence interval -3.6 to 18.3). The estimated relative risk of dying in hospital is 1.59 but the 95% confidence interval is wide (0.84 to 3.01). CONCLUSION Although the death rates are slightly higher in those admitted to hospital for relief care than in those awaiting admission, the difference was not significant, and the death rate in both groups was reassuringly small.

Abstract
IgG- and C3b-coated erythrocytes were used to investigate splenic Fc-receptor function and hepatic C3b-receptor function by measurements of their blood clearance. Most patients with glomerular disease including those who were HLA, A1, B8, DR3 had normal Fc-receptor function. Occasional individuals with persistent glomerulonephritis had delayed clearance unrelated to disease activity. In rapidly progressive glomerulonephritis, the phenomenon of 'reticulo-endothelial blockade' was confirmed. C3b-receptor function was normal in most patients with persistent glomerulonephritis. A defect in splenic Fc-receptor function hepatic C3b-receptor function is unlikely to underlie persistent glomerulonephritis.

Abstract
Antibodies to three major antigens of the non-histone or saline-extractable nuclear antigen (ENA) complex were sought by counterimmunoelectrophoresis (CEP) in three groups of sera which gave different patterns in the immunofluorescence test for antinuclear antibodies (ANA). Precipitins, mainly anti RNP and anti SS-B, were found most commonly (61%) in 70 sera with a speckled ANA pattern but were less frequent (8%) in 61 sera with a homogeneous ANA pattern and exceptional (1%) in 72 sera which showed fibrillar ANA staining. Rim staining was an insensitive indicator of nDNA antibody. An enzyme immunoassay (EIA), specific for anti-SS-B was more sensitive than CEP and identified this antibody in 28 sera, compared with 18 for CEP.
