Abstract
AIM Raman spectroscopy of human tissue can provide a unique biochemical 'fingerprint' that alters with disease progression. Light incident on tissue is scattered and may be altered in wavelength, which can be represented as a Raman spectrum. A confocal fibreoptic Raman probe designed to fit down the accessory channel of a colonoscope has been constructed. This in-vitro study evaluated the accuracy of pathological diagnosis in the colon using probe-based Raman spectroscopy. METHOD Biopsy samples were collected at colonoscopy, snap frozen and stored at -80 °C. Raman spectra with 10-s and 1-s acquisition periods were measured with the probe tip in contact with the mucosal surface of thawed specimens. Mathematical modelling using principal component analysis followed by linear discriminant analysis was used to correlate Raman spectra with histopathological diagnoses. RESULTS Three-hundred and seventy-five Raman spectra were measured from a total of 356 colon biopsies (81 of normal colon mucosa, 79 of hyperplastic polyps, 92 of adenomatous polyps, 64 of adenocarcinoma and 40 of ulcerative colitis) from 177 patients. Spectral classification accuracies comparing pathology pairs ranged from 72.1 to 95.9% for 10-s acquisitions and from 61.5 to 95.1% for 1-s acquisitions. For a three-group model of normal, adenomatous and adenocarcinoma tissue, accuracies were 74.1% for 10-s acquisitions and 63.5% for 1-s acquisitions. CONCLUSION The confocal Raman probe system can distinguish between different colorectal pathologies. The probe has potential to establish Raman spectroscopy as a clinical tool for instant diagnosis at colonoscopy.

Abstract
Aims In the HORIZONS trial, in-hospital treatment with bivalirudin reduced bleeding and mortality in primary percutaneous coronary intervention (PCI) compared with heparin and routine glycoprotein IIb/IIIa inhibitors (GPI). It is unknown whether this advantage of bivalirudin is observed in comparison with heparins only with GPI used as bailout. Methods and results In the EUROMAX study, 2198 patients with ST-segment elevation myocardial infarction (STEMI) were randomized during transport for primary PCI to bivalirudin or to heparins with optional GPI. Primary and principal outcome was the composites of death or non-CABG-related major bleeding at 30 days. This pre-specified analysis compared patients receiving bivalirudin (n = 1089) with those receiving heparins with routine upstream GPI (n = 649) and those receiving heparins only with GPI use restricted to bailout (n = 460). The primary outcome death and major bleeding occurred in 5.1% with bivalirudin, 7.6% with heparin plus routine GPI (HR 0.67 and 95% CI 0.46–0.97, P = 0.034), and 9.8% with heparins plus bailout GPI (HR 0.52 and 95% CI 0.35–0.75, P = 0.006). Following adjustment by logistic regression, bivalirudin was still associated with significantly lower rates of the primary outcome (odds ratio 0.53, 95% CI 0.33–0.87) and major bleeding (odds ratio 0.44, 95% CI 0.24–0.82) compared with heparins alone with bailout GPI. Rates of stent thrombosis were higher with bivalirudin (1.6 vs. 0.6 vs. 0.4%, P = 0.09 and 0.09). Conclusion Bivalirudin, started during transport for primary PCI, reduces major bleeding compared with both patients treated with heparin only plus bailout GPI and patients treated with heparin and routine GPI, but increased stent thrombosis.

Abstract
BACKGROUND Several cross-sectional studies have shown an association between exposure to life events and psychological problems in adults with intellectual disability (ID). To establish life events as a risk factor, prospective designs are needed. METHODS Support staff informants provided data on the psychological problems of 68 adults with ID and their recent exposure to life events. Using data collected on the same sample 3.5 to 4 years earlier, prospective analysis of the relationships between life events exposure and psychological problems over time was explored. RESULTS Hierarchical linear regression analyses demonstrated a contribution of life events to the prediction of later psychological problems after controlling for earlier psychological problems. Exploratory analyses showed that the relationship between life events and psychological problems might be unidirectional, and non-spurious; remaining present once the impact of other correlates of psychological problems was controlled. CONCLUSIONS These data offer support for the status of life events (with a negative valence) as a risk factor for psychological problems in adults with ID. To establish life events as a causal risk factor, research is needed to examine the mechanisms via which life events have their impact on psychological well-being.

Abstract
BACKGROUND In patients with ST-segment elevation myocardial infarction (STEMI) triaged to primary percutaneous coronary intervention (PCI), anticoagulation often is initiated in the ambulance during transfer to a PCI site. In this prehospital setting, bivalirudin has not been compared with standard-of-care anticoagulation. In addition, it has not been tested in conjunction with the newer P2Y12 inhibitors prasugrel or ticagrelor. DESIGN EUROMAX is a randomized, international, prospective, open-label ambulance trial comparing bivalirudin with standard-of-care anticoagulation with or without glycoprotein IIb/IIIa inhibitors in 2200 patients with STEMI and intended for primary percutaneous coronary intervention (PCI), presenting either via ambulance or to centers where PCI is not performed. Patients will receive either bivalirudin given as a 0.75 mg/kg bolus followed immediately by a 1.75-mg/kg per hour infusion for ≥30 minutes prior to primary PCI and continued for ≥4 hours after the end of the procedure at the reduced dose of 0.25 mg/kg per hour, or heparins at guideline-recommended doses, with or without routine or bailout glycoprotein IIb/IIIa inhibitor treatment according to local practice. The primary end point is the composite incidence of death or non-coronary-artery-bypass-graft related protocol major bleeding at 30 days by intention to treat. CONCLUSION The EUROMAX trial will test whether bivalirudin started in the ambulance and continued for 4 hours after primary PCI improves clinical outcomes compared with guideline-recommended standard-of-care heparin-based regimens, and will also provide information on the combination of bivalirudin with prasugrel or ticagrelor.

Abstract
UNLABELLED PROBLEM/OBJECTIVES: Permanent childhood hearing loss has major negative impacts on children's health and development. To improve outcomes, universal newborn hearing screening (UNHS) has been implemented widely. However, high-quality evidence on its efficacy was lacking. To address this evidence gap, we conducted the Longitudinal Outcomes of Children with Hearing Impairment (LOCHI) study to directly compare outcomes of early- and late-identified children. This paper investigates whether early performance measured shortly after initial amplification predicts language development at 3 years of age. METHODOLOGY This is a prospective, population-based study. We assessed outcomes at 6- and 12-months after amplification, and then at 3 and 5 years of age. Main outcome measures included directly-assessed language, receptive vocabulary, speech production; and parent-reported functional performance in everyday life. A range of demographic and audiological information was also collected at evaluation intervals. RESULTS About 450 children participated, and 3-year outcomes scores were available for 356 participants. Multiple regression analysis revealed that early language scores or functional performance ratings were significant predictors of 3-year outcomes. Other significant predictors included the presence or absence of additional disabilities, severity of hearing loss, and age at cochlear implant activation. CONCLUSIONS Early performance, either directly-assessed language ability (PLS-4) or parent-reported functional ratings (PEACH), were significant predictors of 3-year outcomes; along with presence or absence of additional disabilities, severity of hearing loss, and age at CI activation. Earlier implantation is possible with early detection of hearing loss via UNHS. Monitoring performance after initial amplification allows preventive strategies to be implemented early to improve outcomes.

Abstract
BACKGROUND Colorectal cancer (CRC) is the third-leading cause of cancer death for both men and women in the USA. Despite consensus recommendations for screening, just over half of eligible adults nationally have undergone screening. We therefore implemented a programme to improve the rate of CRC screening. METHODS This study was conducted in the Utah Health Research Network and the University of Utah Community Clinics, a 100 000 patient, seven-practice, university-owned system offering primary and secondary care and ancillary services including endoscopy. We focused on patients aged >or=50 who were seen between 1 January 2003 and 31 October 2006, and who were not current for CRC screening at the time of the visit. The study included a three-phase INTERVENTION electronic medical record (EMR) reminders, physician and medical assistant (MA) education about CRC screening guidelines, and redesign of patient visit workflow with an expanded role for MAs to review patients' CRC screening status and recommend testing when appropriate. With patient agreement, the MA entered a preliminary order in the EMR, and the physician confirmed or rejected the order. The primary outcome measure was the rate of screening colonoscopy ordered for eligible patients. RESULTS The baseline colonoscopy referral rate was 6.0%. Provider education and electronic reminders had minimal immediate impact on screening rates. Addition of the expanded MA role was associated with a sustained increase in colonoscopy referral order rate to 13.4%, a relative improvement of 123%. CONCLUSIONS The MA can play a key role in improving CRC screening rates as part of a redesigned system of primary care.

Abstract
Intestinal adenocarcinomas are rare but have been described in the literature. The present case is unusual in both its clinical presentation and in the distribution of metastatic lesions. The sequestrum formation and pathological fracture present are most commonly associated with osteomyelitis in horses and the details of the case highlight the need for differential diagnosis in these particular circumstances and of which clinicians should be aware.

Abstract
The aim of this study was to determine normative values for minimal response levels (MRLs) for normal-hearing young infants using insert earphone visual reinforcement audiometry (VRA). The subjects were 46 normally developing infants aged between 33 and 50 weeks who had hearing sensitivity assumed to be within normal limits and no evidence of middle ear dysfunction. VRA was carried out using insert earphones with warble tone stimuli, generated from an AC33 audiometer and calibrated to ISO 389-2 for insert earphones in adults. The frequencies assessed were 500 Hz, 1 kHz, 2 kHz and 4 kHz. In total, 102 MRLs were obtained, with an approximately equal number of MRLs per frequency. Mean MRLs for 500 Hz, 1 kHz, 2 kHz and 4kHz were 16 dB HL, 13 dB HL, 7 dB HL and 6 dB HL, respectively. Standard deviations were close to 6 dB for all frequencies. Mean MRLs at the lower frequencies were significantly greater than MRLs at the two higher frequencies. MRLs did not vary significantly with age. The results obtained from this study suggest significant infant adult differences when testing hearing using VRA with insert earphones, particularly at lower frequencies. Possible reasons for this and the clinical use of these normative values are discussed.

Abstract
e17563 Background: Progress in cancer treatment is very much dependent on the effective interaction of several specialties. To facilitate the process, more and more multidisciplinary clinics have been created over the last decade, especially in academic settings. This approach has been more established in the academic setting to help facilitate better patient accrual to clinical trials. Although there are studies confirming the effectiveness of this approach in fulfilling practice guidelines, there is however no study of patients’ expectations at a multidisciplinary clinic, especially in regard to the patients’ attitude towards clinical trials. This study examines patients’ preferences for services offered in an academic Methods: Surveys were handed to patients at the time of the first clinic visit and at time of progressive disease. The surveys were designed as a self directed questionnaire with the following questions that were rated on an ordinate scale from not at all important (score 1) to extremely important value (score 7): to see all doctors the same day; to be treated at a university-based cancer center; to have everything completely explained; to have the first appointment within 10 days; to know your cases will be discussed at conference; to have help with transportation and medical costs; and to participate in clinical trials. Results: 94 patients were surveyed at the GI and Thoracic Multimodality Clinic. Among patients the highest preference was “to have every thing explained,” score 6.7 (6.5–7.0, CI), immediately followed by the discussion at the multidisciplinary conference, score 6.6 (6.5–6.8, CI). Clinical trials ranked lowest, score 4.8 (4.4–5.2,CI). The difference was statistically significant, p = 0.012. There was no difference between GI and Thoracic Multimodality Clinic patients. Patients with progressive cancers showed a slightly higher interest in clinical trials, but still ranking trials below most other services. Conclusions: Patients value complete explanations of the disease and management plan far more than they value clinical trials. Considering that nationwide less than 5% of cancer patients are enrolled in clinical studies, it is important for physicians to explain the merit of clinical trials to patients and public. No significant financial relationships to disclose.

Abstract
Following recent torsional oscillator measurements which appear to show the 'non-classical rotational inertia' which characterizes a supersolid, a number of experiments have searched for evidence of unusual behavior in other properties. We have developed a new technique for measuring the shear modulus of solid helium at low frequencies and small strains. In hexagonal close packed (4)He, the shear modulus increases dramatically below 200 mK, the temperature range where decoupling is seen in torsional oscillators. The modulus anomaly is frequency independent, depends strongly on strain amplitude, and is very sensitive to (3)He impurities. In these and other ways, the shear modulus closely mirrors the torsional oscillator behavior and it is clear that the two phenomena are closely related. We attribute the shear modulus effects to the elastic response of mobile dislocations and their pinning by (3)He impurities at low temperatures. A question then arises: are the modulus increases responsible for the frequency changes seen in torsional oscillator experiments? The expected frequency shifts appear to be much too small to explain the apparent decoupling, nor can elastic effects explain the 'blocked annulus' results or the behavior in small pores. In order to clarify the relationship between the shear modulus and torsional oscillator behaviors, we have recently made modulus measurements on (3)He, where no supersolid response is expected. Since dislocation motion depends on crystal structure it was important that these measurements be extended to the hexagonal close packed phase of (3)He, not just the body centered cubic phase.

Abstract
Objectives To see whether revised screening standards and health-professional training are associated with changes in the performance of a neonatal screening programme for congenital hypothyroidism (CHT). Methods Screening data from the regional screening service in Durham and Newcastle, which covers north-east England and North Cumbria. Setting We assessed the timing of the different stages of the screening process leading up to the introduction of the revised guidelines between April 2004 and March 2005 (year 1) and afterwards between April 2005 and March 2006 (year 2) in all babies notified as having CHT. We also assessed the interval between sampling and specimen arrival in the laboratory at the beginning and end of year 2 in all babies screened. Results Twenty-three babies tested positive or borderline in year 1 and 18 babies in year 2. There was reduced variability in the overall time from birth to notification in year 2 versus year 1 ( P = 0.001). This reduction was a consequence of a reduced interval between sample collection and arrival in the laboratory ( P = 0.047) and for the laboratory to notify the positive test result ( P = 0.003). There was a reduction in the mean time from sampling to receipt by the laboratory in the 2997 babies screened in the final month compared with the 2498 babies screened in the first month of year 2 ( P = 0.01). Conclusion There was an improvement in neonatal screening programme performance around the time that revised neonatal screening guidelines were introduced. This highlights the importance of ongoing education and training for those involved in screening programmes.

Abstract
6609 Introduction: Programmed wireless notebook computers (e-tablets) can collect review of systems (ROS) data at point of care. Patients complete surveys in the clinic waiting area; a report is generated for the subsequent clinical visit. Are e-tablets a feasible, acceptable method for collecting data directly from patients in an academic cancer clinic? Can they reliably collect other survey data? Methods: We used PACE e-tablets (SOS, Inc.) to administer Functional Assessment of Cancer Therapy (FACT)-G, FACT-B, MD Anderson Symptom Inventory (MDASI), FACIT-Fatigue, and Self Efficacy instruments, in addition to the PACE Patient Care Monitor (PCM) ROS survey. Participants were 66 breast cancer patients in Duke Breast Cancer Clinic. At 4 visits in 6 months, participants completed all electronic and 1 paper survey. Subscales were compared using paired t-tests. Patients completed an electronic survey of satisfaction with PCM. Results: Mean age, 55 (SD 12); 77% Caucasian; 49% no college degree; 68% married; 61% metastatic cancer. Patients strongly supported e-tablets: easy to read (94%), easy to respond to questions (98%), weight of computer comfortable (87%). Satisfaction increased over time: helpful for reporting symptoms (75–88%), would recommend PCM to other patients (87–94%). 75% indicated PCM helped them remember symptoms to discuss with the clinician. Responses to paper and electronic surveys were nearly identical for 3 of 4 FACT-G, and all FACT-B, MDASI, and FACIT-Fatigue subscales (all p>0.31). Responses on FACT-G Social Wellbeing and 4 Self Efficacy subscales differed from paper to electronic (all p<0.006, all electronic scores poorer). Conclusions: Patients are satisfied with e-tablets. E- tablets furnish comparable data to those collected by paper on nearly all scales tested. PCM offers a valid, feasible method for collecting research-quality, clinically relevant data from patients in outpatient academic oncology. No significant financial relationships to disclose.

Abstract
Three new crystal forms of satellite panicum mosaic virus (SPMV) were grown and their structures solved from X-ray diffraction data using molecular replacement techniques. The crystals were grown under conditions of pH and ionic strength that were appreciably different then those used for the original structure determination. In rhombohedral crystals grown at pH 8.5 and low ionic strength PEG 3350 solutions, Fourier syntheses revealed segments, ten amino acid residues long, of amino-terminal polypeptides not previously seen, as well as masses of electron density within concavities on the interior of the capsid, which appeared in the neighborhoods of icosahedral five- and threefold axes. The densities were compatible with secondary structural domains of RNA, and they included a segment of double helical RNA of about four to five base pairs oriented, at least approximately, along the fivefold axes. The distribution of RNA observed for SPMV appears to be distinctly different than the encapsidated nucleic acid conformation previously suggested for another satellite virus, satellite tobacco mosaic virus. This study further shows that analysis of viruses in crystals grown under different chemical conditions may reveal additional information regarding the structure of encapsidated RNA.

Abstract
OBJECTIVE Platelets and monocytes possess haemostatic properties, but the clinical effect of platelet-monocyte interactions on haemostasis following coronary surgery is not known. The study characterises the platelet and monocyte responses in cardiac surgery and its impact on haemostasis. METHODS In 1342 patients, changes in white blood cell counts (WBC), monocyte counts and platelet counts were measured. PMC formation was analysed by flow-cytometry using monoclonal antibodies against pan-leucocyte marker CD45, monocyte marker CD14 and platelet marker CD42. TF expression was determined using monoclonal antibodies against, CD45, CD14 and human-TF. Continuous variables were expressed as mean+/-SD. Changes in monocyte and platelet counts over time were considered as repeated measures data, and analysed using Generalised Estimating Equations (GEE). Multivariate regression analysis was used to evaluate the effect of several factors on blood loss. RESULTS A monocytosis occurs with on-pump coronary surgery, but is less pronounced than with off-pump surgery. No difference was seen in patients having redo-surgery or more complex cardiac surgery. Factors associated with monocytosis on multivariate analysis were higher body mass index (p=0.02), diabetes (p=0.035) and smoking (p=0.01). Older patients manifested a lower response (p<0.001). Cross-clamp fibrillation was associated with a lower (p=0.048) monocytic response than was cardioplegia. PMC formation dropped following administration of heparin, peaked at 5 min of CPB, and declined by 2h of CPB (p=0.04). A return towards preoperative levels was found during postoperative days 1-5. No significant change in monocyte TF expression occurred. The mean postoperative blood loss was 581.2+/-292.8 ml, and inversely related to increasing preoperative platelet counts (p<0.001), and to higher monocyte % counts (p=0.012). Patients, who were female (p<0.001), had higher body mass indices (p<0.001), and higher core body temperatures during surgery (p=0.013), as well as patients having perioperative aprotinin (p<0.001) related to less blood loss. CONCLUSIONS A higher postoperative platelet count as well as monocyte% significantly and independently decreases postoperative blood loss following cardiac surgery.

Abstract
Two experiments were conducted to determine the effect of estradiol cypionate (ECP), when incorporated into a conventional GnRH-PGF(2alpha)-GnRH timed artificial insemination protocol (Ovsynch), on systemic estradiol (E(2)), time and incidence of ovulation, luteal development, and conception rate in Holstein cows. Our objective was to determine if administration of 0.25 mg of ECP at the time of the second GnRH injection would effectively synchronize ovulation and increase conception rate. In Experiment 1, lactating Holstein cows (n = 23; 58.7 +/- 1.2 d in milk) were synchronized with PGF(2alpha) (at d -10). Ten days later, Ovsynch was initiated with the administration of 100 mug of GnRH (d 0) followed by PGF(2alpha) on d 7. On d 9, cows were assigned randomly to be treated with either GnRH + 0.25 mg of ECP (OVS-ECP; n = 11) or GnRH and 1 mL of cottonseed oil (OVS-C; n = 12). Ovarian activity was monitored by ultrasonography on d 0, 7, and 9. To determine the time of ovulation, ultrasound examinations were conducted at 12 and 20 h posttreatment and then at least every 3 h until either 36 h posttreatment or ovulation was observed. Blood samples were collected on d 0, 7, 9, and 16 for progesterone analysis. Blood samples also were collected at the time of treatment (d 9, 0 h) and at 6, 12, 20, and 28 h for E(2) analysis. Incidence of ovulation did not differ between treatments. Mean ovulation time relative to the second GnRH administration was similar between treatments. Serum progesterone concentration did not differ between treatments at any time. Serum E(2) concentration was not different at the time of treatment (0 h); however, mean E(2) concentration was greater for the OVS-ECP group at 6 and 12 h after treatment compared with OVS-C. In Experiment 2, lactating dairy cows (n = 333) in 3 commercial herds were randomly assigned to OVS-ECP (n = 169) or OVS-C (n = 164). Cows were inseminated 22 to 24 h posttreatment. Conception rates did not differ between treatments. Estradiol cypionate treatment was successful in increasing serum E(2) when administered at the time of the second dose of GnRH in the Ovsynch protocol. Conception rates, however, were not affected by treatment.

Abstract
The protein thaumatin was studied as a model macromolecule for crystallization in microgravity-environment experiments conducted on two US Space Shuttle missions (USML-2 and LMS). In this investigation, we have evaluated and compared the quality of space- and earth-grown thaumatin crystals using X-ray diffraction analyses, and characterized them according to crystal size, diffraction resolution limit and mosaicity. Two different approaches for growing thaumatin crystals in the microgravity environment, dialysis and liquid-liquid diffusion, were employed as a joint experiment by our two investigative teams. Thaumatin crystals grown in a microgravity environment were generally larger in volume and the total number of crystals was less, relative to crystals grown on earth. They diffracted to significantly higher resolution and with improved diffraction properties, as judged by relative plots of I/sigma versus resolution. The mosaicity of space-grown crystals was significantly less than that of crystals grown on earth. Increased concentrations of protein in the crystallization chambers in microgravity led to larger crystals. The data presented here lend further support to the idea that protein crystals of improved quality can be obtained in a microgravity environment.

Abstract
Three crystal forms of the sweet-tasting protein thaumatin from the African berry Thaumatococcus daniellii have been grown. These include two naturally occurring isoforms, A and B, that differ by a single amino acid, and a recombinant form of isoform B expressed in yeast. The crystals are of space groups C2 with a = 117.7, b = 44.9, c = 38.0 A, and beta = 94.0 degrees, P2(1)2(1)2(1) with a = 44.3, b = 63.7 and c = 72.7 A, and a tetragonal form P4(1)2(1)2 with a = b = 58.6 and c = 151.8 A. The structures of all three crystals have been solved by molecular replacement and subsequently refined to R factors of 0.184 for the monoclinic at 2.6 A, 0.165 for the orthorhombic at 1.75 A, and 0.181 for the tetragonal, also at 1.75 A resolution. No solvent was included in the monoclinic crystal while 123 and 105 water molecules were included in the higher resolution orthorhombic and tetragonal structures, respectively. A bound tartrate molecule was also clearly visible in the tetragonal structure. The r.m.s. deviations between molecular structures in the three crystals range from 0.6 to 0.7 A for Calpha atoms, and 1.1 to 1.3 A for all atoms. This is comparable to the r.m.s. deviation between the three structures and the starting model. Nevertheless, several peptide loops show particularly large variations from the initial model.

Abstract
Recent evidence supports involvement of the acute phase protein haptoglobin in numerous events of mammalian reproduction. The objective of this study was to determine whether haptoglobin mRNA was expressed in the bovine ovary and oviduct, and to evaluate whether expression of haptoglobin mRNA in reproductive tissues and liver was associated with a specific phase of the bovine oestrous cycle. Oestrus was synchronized in Holstein cows by prostaglandin injection and tissues were collected during the luteal and peri-oestrous stages of the oestrous cycle. Total RNA was isolated and reverse-transcription polymerase chain reaction (RT-PCR) was performed using primers designed against regions of similarity in human, rat and mouse haptoglobin sequences. Haptoglobin mRNA expression was detected in oviductal cells and liver, during both stages of the oestrous cycle, but not in ovarian follicular cells. The 302 bp PCR product was determined to share 82-83% identity with reported primate haptoglobin sequences. Analysis by Northern blotting revealed 1.2 and 1.4 kb haptoglobin mRNA transcripts in the oviduct and liver, and indicated that hepatic haptoglobin mRNA expression was elevated above basal levels in a greater proportion of peri-oestrous cows (4/4) than luteal cows (1/5). Haptoglobin cDNA was cloned and in vitro transcribed to generate probes for in situ hybridization. Haptoglobin mRNA was detected in the liver, but not in the ovary or oviduct. We conclude that haptoglobin mRNA expression in the bovine liver is up-regulated during the peri-oestrous phase of the oestrous cycle, and that the bovine oviduct expresses a low level of haptoglobin mRNA constitutively. This temporal pattern of haptoglobin mRNA expression would expose reproductive tissues to elevated concentrations of serum haptoglobin during the peri-oestrous stage, and suggests that haptoglobin may be important in reproductive events occurring during this time period.

Abstract
This report describes a sensitive and specific high-performance liquid chromatography (HPLC)-electrospray ionization-tandem mass spectrometry (MS-MS) method for the detection of subnanogram concentrations of fentanyl and its metabolite norfentanyl in human plasma. The assay was based on a liquid-liquid extraction of 0.5 mL of human plasma, with a lower limit of quantitation (LLOQ) of 0.05 ng/mL. Sample extracts were analyzed using a ThermoQuest TSQ MS-MS interfaced with a Hewlett-Packard series 1100 HPLC and a Phenomenex (30 x 2.00-mm, 5 microLuna C18(2)) column. The intra-assay precision and accuracy ranged from 2.1 to 12.5% for both analytes at concentrations of 0.1, 0.5, 1.0, and 10 ng/mL. The interassay accuracy and precision ranged from 7.34 to 10.95%.

Abstract
Objective To assess whether differences in safety profiles between nevirapine (NVP) and efavirenz (EFV), as observed in the 2NN study, translated into differences in ‘health related quality of life’ (HRQoL). Design A sub-study of the 2NN study, with antiretro-viral-naive patients randomly allocated to NVP (once or twice daily), EFV or NVP+EFV, in addition to stavudine and lamivudine. Methods Comparing differences in changes of HRQoL over 48 weeks as measured with the Medical Outcomes Study HIV Health Survey (MOS-HIV) questionnaire, using analysis of variance. Results The 2NN study enrolled 1216 patients. No validated questionnaires were available for 244 patients, and 55 patients had no HRQoL data at all, leaving 917 patients eligible for this sub-study. A total of 471 (51%) had HRQoL measurements both at baseline and week 48. The majority (69%) of patients without HRQoL measurements did, however, complete the study. The change in the physical health score (PHS) was 3.9 for NVP, 3.4 for EFV and 2.4 for NVP+EFV ( P=0.712). For the mental health score (MHS) these values were 6.1, 7.0 and 3.9, respectively ( P=0.098). A baseline plasma HIV-1 RNA concentration (pVL) ≥100 000 copies/ml and a decline in pVL (per log10) were independently associated with an increase of PHS. An increase of MHS was only associated with pVL decline. Patients experiencing an adverse event during follow-up had a comparable change in PHS but a significantly smaller change in MHS, compared with those without an adverse event. Conclusions First-line ART containing NVP and/or EFV leads to an improvement in HRQoL. The gain in HRQoL was similar for NVP and EFV, but slightly lower for the combination of these drugs.

Abstract
PURPOSE This phase II study was undertaken to determine the efficacy of adding infusional fluorouracil (FU) to the chemotherapy doublet of gemcitabine and cisplatin in patients with advanced pancreatic cancer. PATIENTS AND METHODS The eligibility criteria included histologically or cytologically confirmed adenocarcinoma of the pancreas that was either unresectable or metastatic. No prior gemcitabine therapy was allowed. Patients received a combination of gemcitabine 1000 mg/m2 intravenously (IV) on days 1, 8, and 15; cisplatin 50 mg/m2 IV on days 1 and 15; and FU 175 mg/m2/d from days 1 to 15 by continuous IV infusion. Cycles were repeated every 28 days. Objective tumor response and toxicity were evaluated according to the World Health Organization criteria. RESULTS A total of 47 patients (median age, 57 years; males, 59%) were enrolled. Sixteen patients had locally advanced (LA) disease, and 31 patients had metastatic disease. A total of 183 cycles of chemotherapy were administered. In patients with metastatic disease (n = 31), the probability of survival at 6 and 12 months was 66% and 34%, respectively. Objective partial response or stable disease was observed in 26% (90% confidence interval [CI], 0.14 to 0.41) and 61% (90% CI, 0.45 to 0.74) of patients, respectively. In patients with LA disease (n = 16), there were three partial responses (19%; 90 CI, 0.07 to 0.39). One patient in this group was successfully resected after FU-based radiotherapy. The most common grade 3 to 4 toxicities were neutropenia (60%), thrombocytopenia (42%), and anemia (26%). Thirteen patients were hospitalized for treatment-related complications. CONCLUSION The combination of gemcitabine, cisplatin, and infusional FU has significant activity in patients with advanced pancreatic cancer.

Abstract
Sequencing of the genomes of Mycobacterium tuberculosis H37Rv and Streptomyces coelicolor A3(2) identified putative genes for an NAD(+)-dependent DNA ligase. We have cloned both open reading frames and overexpressed the protein products in Escherichia coli. In vitro biochemical assays confirm that each of these proteins encodes a functional DNA ligase that uses NAD(+) as its cofactor. Expression of either protein is able to complement E. coli GR501, which carries a temperature-sensitive mutation in ligA. Thus, in vitro and in vivo analyses confirm predictions that ligA genes from M. tuberculosis and S. coelicolor are NAD(+)-dependent DNA ligases.

Abstract
Recent research has highlighted the role of expressed emotion by ward staff in determining the well-being of psychiatric inpatients. Existing methods of assessing staff expressed emotion involve standardized interviews and are expensive and time-consuming. We report the development of a questionnaire measure of expressed emotion in staff as perceived by patients. In study 1, factor analysis of items administered to patients in a variety of settings led to the development of a questionnaire with three subscales: supportiveness, criticism and intrusiveness. In study 2, the test-retest reliability of the questionnaire was found to be adequate, and some evidence of concurrent validity for the scale was obtained against expressed emotion rated from staff speech samples. In study 3, the scale was shown to have good concurrent validity against the ward atmosphere scale, and scores were found to be independent of insight or experience of admission to hospital. The perceived expressed emotion in staff scale is a convenient measure, which may have utility for both research and clinical purposes.

Abstract
Patients with Hurler syndrome (mucopolysaccharidosis type-IH) and metachromatic leukodystrophy (MLD) develop significant skeletal and neurologic defects that limit their survival. Transplantation of allogeneic hematopoietic stem cells results in partial correction of the clinical manifestations. We postulated that some of these defects may be corrected by infusion of allogeneic, multipotential, bone marrow-derived mesenchymal stem cells (MSC). Patients with Hurler syndrome (n = 5) or MLD (n = 6) who previously underwent successful bone marrow transplantation from an HLA-identical sibling were infused with 2-10 x 10(6)/kg MSCs, isolated and expanded from a bone marrow aspirate of the original donor. There was no infusion-related toxicity. In most recipients culture-purified MSCs at 2 days, 30-60 days and 6-24 months after MSC infusion remained of host type. In two patients the bone marrow-derived MSCs contained 0.4 and 2% donor MSCs by FISH 60 days after MSC infusion. In four patients with MLD there were significant improvements in nerve conduction velocities after MSC infusion. The bone mineral density was either maintained or slightly improved in all patients. There was no clinically apparent change in patients' overall health, mental and physical development after MSC infusion. We conclude that donor allogeneic MSC infusion is safe and may be associated with reversal of disease pathophysiology in some tissues. The role of MSCs in the management of Hurler syndrome and MLD should be further evaluated.

Abstract
Searching the Internet effectively necessitates the use of contemporary software programs commonly known as "search engines" to locate desired and meaningful information. Knowing how to effectively and efficiently utilize such search engines is critical for effective and efficient knowledge-seeking activities by the practitioner. Three categories of search engines are described in this article along with an explanation of strategies to maximize the efficiency of searching by appropriately using keywords and supplemental search operators. Examples of major search engines are included in the discussion.
