Abstract
BACKGROUND AND AIMS Exercise remains a key component of nonalcoholic fatty liver disease (NAFLD) treatment. However, mechanisms underpinning the improvements in NAFLD seen with exercise are unclear. Exercise improved liver fat and serum biomarkers of liver fibrosis in the NASHFit trial. We investigated exercise's mechanism of benefit by conducting a post hoc analysis of these data to determine the relationship between serum fibroblast growth factor (FGF) 21, which is implicated in NAFLD development, and exercise. METHODS In the 20 wk NASHFit trial, patients with nonalcoholic steatohepatitis (NASH) were randomized to receive moderate-intensity aerobic exercise training or standard clinical care. Mediterranean-informed dietary counseling was provided to each group. Change in serum FGF21 was measured after an overnight fast. RESULTS There was a significant improvement in serum FGF21 with exercise training compared to standard clinical care (p = 0.037) with serum FGF21 reducing by 22% (-243.4 +/-349 ng/mL) with exercise vs. a 34% increase (+88.4 ng/mL +/-350.3 ng/mL) with standard clinical care. There was a large inverse association between change in serum FGF21 and change in cardiorespiratory fitness (VO2peak) (r = -0.62, 95% CI -0.88 to -0.05, p = 0.031), and on multivariable analysis, change in VO2peak remained independently associated with change in FGF21 (β = -44.5, 95% CI -83.8 to -5.11, p = 0.031). CONCLUSIONS Serum FGF21 is markedly decreased in response to aerobic exercise training, offering a novel mechanism to explain the observed reduction in liver fat and improvement in serum biomarkers of liver fibrosis in patients with NASH who do exercise.

Abstract
BACKGROUND AND AIMS NASH is a common disease associated with increased rates of thromboembolism (TE). Although exercise training can lessen thrombotic risk in patients with vascular disease, whether similar findings are observed in patients with NASH is open for study. APPROACH AND RESULTS We conducted a 20-week randomized controlled clinical trial involving patients with biopsy-confirmed NASH. Patients were randomly assigned (2:1 ratio) to receive either an exercise training program or standard clinical care. The primary endpoint was change in plasminogen activator inhibitor 1 (PAI-1) level, an established thrombotic biomarker. Twenty-eight patients were randomly assigned (18 exercise training and 10 standard clinical care). PAI-1 level was significantly decreased by exercise training when compared to standard clinical care (-40 ± 100 vs. +70 ± 63 ng/ml; p = 0.02). Exercise training decreased MRI proton density fat fraction (MRI-PDFF; -4.7 ± 5.6 vs. 1.2 ± 2.8% absolute liver fat; p = 0.01); 40% of exercise subjects had a ≥30% relative reduction in MRI-PDFF (histological response threshold) compared to 13% for standard of care (p < 0.01). Exercise training improved fitness (VO2 peak, +3.0 ± 5.6 vs. -1.8 ± 5.1 ml/kg/min; p = 0.05) in comparison to standard clinical care. CONCLUSIONS This clinical trial showed that, independent of weight loss or dietary change, exercise training resulted in a significantly greater decrease in thrombotic risk than standard clinical care in patients with NASH, in parallel with MRI-PDFF reduction and improvement in fitness. Future studies are required to determine whether exercise training can directly impact patient outcomes and lower rates of TE.

Abstract
BACKGROUND Lifestyle changes, including physical activity, are the cornerstones of the treatment of nonalcoholic fatty liver disease (NAFLD). For unclear reasons, most NAFLD patients do not achieve the recommended amount of weekly activity. AIMS Our aim was to measure perceived barriers to physical activity and enablers to exercise intervention. METHODS Consecutive subjects aged 18-70 with NAFLD were prospectively enrolled. An exercise motivation questionnaire was administered to assess current behaviors and perceived barriers. RESULTS Eighty-seven subjects (60% female) were enrolled with mean age 52 years and mean body mass index (BMI) 34.5 kg/m2. Metabolic comorbidities were common: 49% had hyperlipidemia, 42% hypertension, and 40% diabetes. The majority (75%) did not achieve ≥ 150 min/week of physical activity. Ninety-one percent agreed that activity was important in improving NAFLD; 88% desired to be more active. Lack of exercise resources and education from treating provider (47%), physical discomfort during exercise (44%), and time constraints (32%) were the most common barriers. Rates of fitness tracker (34%), gym (33%), exercise program (33%), and personal trainer (17%) use were low. CONCLUSIONS While nearly all subjects with NAFLD identify physical activity to be important and desire to be more active, only a few meet activity recommendations. This discordance is due to a perceived lack of resources and education, physical discomfort, and time constraints. Better understanding of these barriers and behaviors are important to improve morbidity and mortality in NAFLD. Future behavioral research removing the identified barriers is of great importance to global public health and should be prioritized.

Abstract
Background Most patients with nonalcoholic fatty liver disease (NAFLD) are physically inactive despite the well-known benefits of physical activity. Telehealth offers promise as a novel way to deliver an exercise training program and increase physical activity. However, the feasibility, safety, and efficacy of telehealth-based exercise programs is unknown in patients with NAFLD. Objective The aim of this study was to determine the feasibility of a directly supervised exercise training program delivered exclusively with telehealth to patients with nonalcoholic steatohepatitis (NASH), the progressive form of NAFLD. Methods In response to COVID-19 research restrictions, we adapted an existing clinical trial and delivered 20 weeks of moderate-intensity aerobic training 5 days a week under real-time direct supervision using an audio–visual telehealth platform. Aerobic training was completed by walking outdoors or using a home treadmill. Fitness activity trackers with heart rate monitors ensured exercise was completed at the prescribed intensity with real-time feedback from an exercise physiologist. Results Three female patients with biopsy-proven NASH were enrolled with a mean age of 52 (SD 14) years. The mean body mass index was 31.9 (SD 5.1) kg/m2. All patients had metabolic syndrome. All patients completed over 80% of exercise sessions (mean 84% [SD 3%]) and no adverse events occurred. Body weight (mean –5.1% [SD 3.7%]), body fat (mean –4.4% [SD 2.3%]), and waist circumference (mean –1.3 in. [SD 1.6 in.]) all improved with exercise. The mean relative reduction in magnetic resonance imaging-proton density fat fraction (MRI-PDFF) was 35.1% (SD 8.8%). Mean reductions in hemoglobin A1c and Homeostatic Model Assessment for Insulin Resistance were also observed (–0.5% [SD 0.2%] and –4.0 [SD 1.2], respectively). The mean peak oxygen consumption (VO2peak) improved by 9.9 (SD 6.6) mL/kg/min. Conclusions This proof-of-concept study found that supervised exercise training delivered via telehealth is feasible and safe in patients with NASH. Telehealth-based exercise training also appears to be highly efficacious in patients with NASH, but this will need to be confirmed by future large-scale trials.

Abstract
Multiplex quantitative real-time PCR (MRT-PCR) using blood can improve the diagnosis of intra-abdominal candidiasis (IAC). We prospectively studied 39 patients with suspected IAC in the absence of previous antifungal therapy. Blood cultures, MRT-PCR, and β-D-glucan (BDG) in serum were performed in all patients. IAC was defined according to the 2013 European Consensus criteria. For MRT-PCR, the probes targeted the ITS1 or ITS2 regions of ribosomal DNA. Candidaemia was confirmed only in four patients (10%), and IAC criteria were present in 17 patients (43.6%). The sensitivity of MRT-PCR was 25% but increased to 63.6% (P = .06) in plasma obtained prior to volume overload and transfusion; specificity was above 85% in all cases. BDG performance was improved using a cutoff > 260 pg/ml, and improvement was not observed in samples obtained before transfusion. In this cohort of high risk of IAC and low rate of bloodstream infection, the performance of non-culture-based methods (MRT-PCR or BDG) was moderate but may be a complementary tool given the limitations of diagnostic methods available in clinical practice. Volume overload requirements, in combination with other factors, decrease the accuracy of MRT-PCR in patients with IAC.

Abstract
Background Many factors impact nutritional status in inflammatory bowel disease (IBD). We undertook this study to evaluate the potential role that abdominal pain has on weight loss and dietary behavior in IBD. Methods This is a retrospective cohort study utilizing data from an IBD registry at our institution between January 1, 2015 and August 31, 2018. Pain scores and nutritional outcomes were derived from validated questionnaires while key associated clinical data were derived from the medical record. Results Three hundred and three patients (154 females; 206 Crohn’s disease) were included in this study. Ninety-six patients (31.7%) had experienced a 6-lb or greater weight loss in the prior month. On multivariate analysis, abdominal pain and anxious/depressed state were independently associated with weight loss, while female gender and NSAID use were inversely associated with weight loss (P < 0.05). IBD patients with abdominal pain also reported significantly poorer dietary behavior than those without this symptom. Conclusions Abdominal pain is more likely to result in negative dietary outcomes and independently associated with weight loss in IBD. IBD providers should screen for malnutrition when patients report abdominal pain. We demonstrated that IBD patients with abdominal pain, anxious or depressed state have poorer nutritional outcomes, regardless of disease activity state. These findings reinforce the importance of screening for malnutrition in IBD patients with one or more of these symptoms.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is the leading cause of chronic liver disease worldwide affecting upwards of one third the global population. For reasons not fully understood, individuals with NAFLD and its more severe variant, nonalcoholic steatohepatitis (NASH), are at increased risk for venous thromboembolism which significantly increases morbidity and mortality. Lifestyle changes centering around exercise training are the mainstay of treatment for NAFLD/NASH. While exercise training can lessen venous thromboembolic risk in healthy persons and those with cardiovascular disease, whether or not this benefit is seen in patients with NAFLD/NASH remains unknown. In order to better understand how exercise training impacts thrombosis risk in NAFLD, we present the design of a thirty-two week randomized controlled clinical trial of 42 sedentary subjects age 18-69 with biopsy proven NASH. The main aim is to determine the impact of an aerobic exercise training program on the abnormal hemostatic system unique to NAFLD/NASH. The main outcome is change in plasminogen activator inhibitor one level, an established marker for venous thromboembolism. Secondary outcomes include body composition, cardiorespiratory fitness, control of comorbid metabolic conditions (e.g., obesity, hypertension, hyperlipidemia, diabetes), dietary composition, health related quality of life, liver enzymes and histology, NAFLD/NASH disease activity (e.g., biomarkers, clinical decision aids), microbiome, other markers of hemostasis, and PNPLA3 gene expression. The study represents the first clinical trial of an exercise training program to reduce elevated clotting risk in subjects with NAFLD/NASH.

Abstract
Background: Pain perception is critical for detection of noxious bodily insults. Gastrointestinal hypoalgesia in inflammatory bowel disease (IBD) is a poorly understood phenomenon previously linked to poor patient outcomes. We aimed to evaluate the risk factors associated with this condition and to discern characteristics that might differentiate these patients from pain-free quiescent counterparts. Methods: We performed a retrospective analysis using an IBD natural history registry based in a single tertiary care referral center. We compared demographic and clinical features in 3 patient cohorts defined using data from simultaneous pain surveys and ileocolonoscopy: a) active IBD without pain (hypoalgesic IBD); b) active IBD with pain; and c) inactive IBD without pain. Results: One hundred fifty-three IBD patients had active disease and 43 (28.1%) exhibited hypoalgesia. Hypoalgesic IBD patients were more likely to develop non-perianal fistulae (P=0.03). On logistic regression analysis, hypoalgesic IBD was independently associated with male sex, advancing age and mesalamine use, and inversely associated with anxious/depressed state and opiate use. Hypoalgesic IBD patients were demographically and clinically similar to the pain-free quiescent IBD cohort (n=59). Platelet count and C-reactive protein were more likely to be pathologically elevated in hypoalgesic IBD (P=0.03), though >25% did not exhibit elevated inflammatory markers. Conclusions: Hypoalgesia is common in IBD, particularly in male and older individuals, and is associated with an increased incidence of fistulae and corticosteroid use. Novel noninvasive diagnostic tools are needed to screen for this population, as inflammatory markers are not always elevated.

Abstract
Much evidence indicates that iron stored in ferritin is mobilized through protein degradation in lysosomes, but concerns about this process have lingered, and the mechanistic details of its aspects are lacking. In the studies presented here, 59Fe-labeled ferritin was induced by preloading hepatic (HepG2) cells with radiolabeled Fe. Placing these cells in a medium containing desferrioxamine resulted in the loss of ferritin-59Fe, but adding high concentrations of reducing agents or modulating the internal GSH concentration failed to alter the rates of ferritin-59Fe release. Confocal microscopy showed that Fe deprivation increased the movement of ferritin into lysosomes and hyperaccumulation was observed when lysosomal proteolysis was inhibited. It also resulted in the rapid movement of DMT1 to lysosomes, which was inhibited by bafilomycin. Ferrihydrite crystals isolated from purified rat liver/spleen ferritin were solubilized at pH 5 and 7 by GSH, ascorbate, citrate and lysosomal fluids obtained from livers and J774a.1 macrophages. The inhibition of DMT1/Nramp2 and siRNA knockdown of Nramp1 each reduced the transfer of 59Fe from lysosomes to the cytosol; and hepatocyte-specific knockout of DMT1 in mice prevented the release of Fe from the liver responding to EPO treatment, but did not inhibit lysosomal ferritin degradation. We conclude that ferritin-Fe mobilization does not occur through changes in cellular concentrations of reducing/chelating agents but by the coordinated movement of ferritin and DMT1 to lysosomes, where the ferrihydrite crystals exposed by ferritin degradation dissolve in the lysosomal fluid, and the reduced iron is transported back to the cytosol via DMT1 in hepatocytes, and by both DMT1 and Nramp1 in macrophages, prior to release into the blood or storage in ferritin.

Abstract
INTRODUCTION Cortical subarachnoid haemorrhage (cSAH) has multiple aetiologies. No prospective study has reported the long-term progression of the condition. The objective of this study is to describe the clinical and aetiological characteristics of patients with cSAH and to gain insight into prognosis. METHODS We performed a prospective, observational, multi-centre study. Data on clinical and radiological variables were collected; during a one-year follow-up period, we recorded data on mortality, dependence, rebleeding, and the appearance of dementia. RESULTS The study included 34 patients (mean age, 68.3 years; range, 27-89). The most frequent symptoms were headache and focal neurological deficits, which were frequently transient and recurrent. CT scans returned pathological findings in 28 patients (85%). Brain MRI scans were performed in 30 patients (88%), revealing acute ischaemia in 10 (29%), old haemorrhage in 7 (21%), and superficial siderosis in 2 (6%). Aetiology was identified in 26 patients (76.5%): causes were cerebral amyloid angiopathy in 8, ischaemic stroke in 5, vasculitis in 4, reversible posterior encephalopathy in 2, venous thrombosis in 2, reversible cerebral vasoconstriction syndrome in 2, carotid occlusion in 1, Marfan syndrome in 1, and meningeal carcinomatosis in 1. Three patients died during follow-up (2 due to causes related to the cause of cSAH). Three patients developed dementia, 3 had lobar haemorrhages, and one had a second cSAH. CONCLUSIONS The most frequent causes of cSAH in our series were cerebral amyloid angiopathy, ischaemic stroke, and vasculitis. This type of haemorrhage has a worse prognosis than other non-aneurysmal cSAH. There are numerous possible causes, and prognosis depends on the aetiology. In elderly patients, intracranial haemorrhage is frequently associated with cognitive impairment.

Abstract
In a prospective randomized study in patients undergoing carotid endarterectomy, we compared the hemodynamic effects, the quality of induction, and the quality of recovery from a hypnotic drug for the induction of anesthesia with sevoflurane, a target-controlled infusion (TCI) of propofol, or propofol 1.5 microg/kg followed by isoflurane. All patients were premedicated with midazolam and received sufentanil 0.4 microg/kg at induction. The induction of anesthesia was associated with a decrease in arterial blood pressure in all groups, but this was least pronounced in the Sevoflurane group. There were similar a number of episodes of hypotension, hypertension, and tachycardia among groups, but the incidence of bradycardia was less in the TCI group (P < 0.05) compared with the other groups. The duration of episodes of hypotension was shorter (P < 0.05) in the TCI Propofol group (1.9 +/- 2.3 min) compared with the Sevoflurane group (4.7 +/- 3.6 min). The duration of episodes of bradycardia was significantly lower (P < 0.05) in the TCI Propofol group (0.1 +/- 0.5 min) in comparison with the Propofol Bolus group (2.5 +/- 3.9 min). Similar doses of vasoactive drugs were used in all groups. The induction of anesthesia with sevoflurane was associated with inferior conditions for intubation in comparison with both Propofol groups, although the time to intubation was faster in the Sevoflurane group (P < 0.05). The recovery characteristics were similar in the three groups.

Abstract
This paper presents an automated method for extracting anabolic agents from urine samples for their GC-MS analysis by selected-ion monitoring. The sample preparation was carried out in a Hewlett-Packard 7686 SPE PrepStation system. Each 0.6-ml aliquot was hydrolyzed, extracted, dried and trimethylsilyl (TMS) derivatized in a 2-ml vial without any hands-on labor. When sample preparation was finished 2 microl of the extract was injected into the gas chromatograph by split (1:10) mode. Due to the small amount of free space in the 2-ml vials for handling the sample, parameters like time of hydrolysis, type of shaking, number of extractions and some TMS derivatization parameters had to be adjusted to achieve the best recovery for all of the compounds in the screening. Manual and automated sample preparation schemes were compared in terms of linearity, precision, accuracy, limit of detection and recovery data. When large concentrations were analyzed using the automated method no carry-over effect was observed.

Abstract
We report a patient with an undetermined leucodystrophy associated with type 1A oculocutaneous albinism (OCA). Type 1 OCA results from recessive mutations in the tyrosinase gene (TYR) located in 11q14.3. The patient was found by FISH to carry a deletion of at least the first exon of the TYR gene on one chromosome and a (TG) deletion at codon 244/245 on the second chromosome. The existence of the microdeletion suggested that a gene responsible for leucodystrophy was located in the vicinity of the TYR gene. A combination of a test of hemizygosity and contig mapping studies allowed us to map the gene within a 0.6 cM region flanked by microsatellite markers D11S1780 and D11S931.

Abstract
This contribution analyzes the anaerobic digestion process and compares GHG emissions estimated for four different management processes for MSW (Municipal Solid Waste): biogasification, landfilling, composting and incineration. The comparison has been undertaken by considering in the estimation of the emissions the full cycle of MSW treatment, and not only the emissions derived from the fraction of MSW treated by each particular system. For instance, the fraction of MSW not submitted to biological treatment has to be incinerated or deposited in a landfill. The corresponding emissions of these processes have to be considered in the calculations of the final emissions.

Abstract
The analysis of mass isotopomers in blood glucose and lactate can be used to estimate gluconeogenesis (Gneo), glucose production (GP), and, by subtraction, nongluconeogenic glucose release by the liver. At 6 AM, 18 normal subjects received a 7-hour primed constant infusion of [U-13C6] glucose. After a 3-hour baseline period (12 hours of fasting), somatostatin, insulin, hydrocortisone, growth hormone (GH), and glucagon were infused for 4 hours. Glucagon was infused at a low-dose (n = 6) or high-dose (n = 6) concentration for 4 hours and was compared with fasting alone (n = 6). Low-dose glucagon infusion increased plasma glucagon (64 +/- 3 v 44 +/- 7 ng/L, low glucagon v baseline). GP increased above baseline (15.5 +/- 0.5 v 13.8 +/- 0.5 micromol/kg/min, P < .05), which was also greater than fasting alone (11 .5 +/- 0.6 micromol/kg/min, P < .05). The elevation in GP was due to a near doubling of nongluconeogenic glucose release compared with fasting alone (8.3 +/- 0.6 v 4.7 +/- 0.5 micromol/kg/min, P < .01). High-dose glucagon infusion (125 +/- 25 ng/L) increased GP above baseline (15.8 +/- 0.6 v 13.5 +/- 0.5 micromol/kg/min, P < .05), which was also greater than fasting alone (11.5 +/- 0.6 micromol/kg/min, P < .05). The increase in GP was due to an increase in Gneo (8.5 +/- 0.5 v 6.8 +/- 0.7 micromol/kg/min, P < .05) and nongluconeogenic glucose release (7.4 +/- 0.5 v 4.7 +/- 0.4 micromol/kg/min, P < .05) compared with fasting. Low-dose glucagon increases GP only by stimulation of nongluconeogenic glucose release. High-dose glucagon increases GP by an increase in both Gneo and nongluconeogenic glucose release.

Abstract
BACKGROUND A preceding viral syndrome is classically cited as a triggering factor for thrombotic microangiopathy although only anecdotal reports of the causal agent have been documented. CASE REPORT An 84-year-old woman developed thrombotic microangiopathy secondary to diarrhea. An exhaustive etiological work-up documented the presence of Rotavirus alone in the fecal matter. The clinical course was favorable after 9 plasma exchanges using frozen fresh plasma and was associated with disappearance of the Rotavirus. DISCUSSION Enterohemorrhagic Escherichia coli is the most commonly identified infectious agent causing thrombotic microangiopathy. A small number of cases caused by viral agents (particularly retroviruses) have also been documented. To our knowledge, this is the first case attributable to a Rotavirus. In our case, the presence of the Rotavirus in the fecal matter and the favorable clinical course when the virus disappeared would be in favor of its causal role in the pathogenesis of thrombotic micorangiopathy.

Abstract
A first inversion of the backscatter profile and extinction-to-backscatter ratio from pulsed elastic-backscatter lidar returns is treated by means of an extended Kalman filter (EKF). The EKF approach enables one to overcome the intrinsic limitations of standard straightforward nonmemory procedures such as the slope method, exponential curve fitting, and the backward inversion algorithm. Whereas those procedures are inherently not adaptable because independent inversions are performed for each return signal and neither the statistics of the signals nor a priori uncertainties (e.g., boundary calibrations) are taken into account, in the case of the Kalman filter the filter updates itself because it is weighted by the imbalance between the a priori estimates of the optical parameters (i.e., past inversions) and the new estimates based on a minimum-variance criterion, as long as there are different lidar returns. Calibration errors and initialization uncertainties can be assimilated also. The study begins with the formulation of the inversion problem and an appropriate atmospheric stochastic model. Based on extensive simulation and realistic conditions, it is shown that the EKF approach enables one to retrieve the optical parameters as time-range-dependent functions and hence to track the atmospheric evolution; the performance of this approach is limited only by the quality and availability of the a priori information and the accuracy of the atmospheric model used. The study ends with an encouraging practical inversion of a live scene measured at the Nd:YAG elastic-backscatter lidar station at our premises at the Polytechnic University of Catalonia, Barcelona.

Abstract
Stellate ganglion block is a common treatment for neuropathic pain. The technique is not without potentially severe complications when a paratracheal approach is used. A 33-year-old woman complained of atypical facial pain of 15 years' duration with pain intensity of 6 to 8 on a visual analog scale and no pain-free periods upon use of inadequate analgesia. One minute after performing a second stellate ganglion block the patient showed signs of apnea and paralysis of the upper extremities and face, with no involvement of oculomotor muscles or the lower extremities, and no loss of consciousness. Assisted ventilation was started. Signs and symptoms resolved fully after 15 minutes. A few days later, the patient reported having perceived paresthesia in the affected zone during the procedure. Central spread of a portion of local anesthetic by way of the spinal nerve sheath toward the subarachnoid space may cause partial cervical and basal nuclear blockade. Signs would be apnea, involvement of the upper extremities and facial muscles, although paresthesia during the injection is the only evidence supporting this hypothesis. Bone contact and negative aspiration while performing a stellate ganglion block do not guarantee avoidance of complications.

Abstract
We report four cases of adult thrombotic microangiopathy associating diarrhea with severe ischemic colitis. In one case, the intestinal complications was severe and diffuse ischemic colitis, in two cases an inaugural colonic perforation requiring colectomy and in the last case a massive mesenteric infarct. In three cases, histologic examination showed vessel occlusion with microthrombi. Despite treatment with plasma exchange and plasma infusion, death ensued in two cases. Principally described in childhood thrombotic microangiopathy, intestinal complications occur exceptionally in adult thrombotic microangiopathy and are associated with a poor prognosis. Inaugural ischemic colitis revealing an adult thrombotic microangiopathy is also uncommon and thrombotic microangiopathy could be evoked in all patients presenting acute ischemic colitis.

Abstract
A procedure for detecting and confirming 23 anabolic substances and/or metabolites has been developed using a GC-MS-MS ion trap system in full-scan mode. The process used to select the precursor ion, and the optimization of the system parameters used to obtain the daughter ion spectra, are explained. Urine samples were prepared using solid-phase extraction and enzymatic hydrolysis, and after TMS derivatives had been formed, they were injected into the mass spectrometer. This method permits confirmation of the presence of anabolic substances at low ng ml(-1) levels without the need of further purification procedures on the samples. This procedure has been used on more than 2000 urine samples collected from sporting competitions and has made it possible to confirm more than 45 true positive cases which could not have been confirmed using routine GC-MS methods.

Abstract
A totally automated procedure has been developed for the preparation and analysis of 34 basic and neutral drugs in urine samples using an integrated HP 7686 PrepStation-HP 6890 gas chromatographic system. The automated preparation of the sample consisted of a liquid-liquid extraction of 250 microliters urine at alkaline pH with 100 microliters of methyl tert.-butyl ether. After phase separation the organic solvent was automatically placed in the injector of the gas chromatograph and analysed. High recoveries of extraction were obtained. The limits of detection of most of the drugs were less than 0.5 microgram/ml. The method, which allows the preparation and analysis of the samples to be completely synchronised, showed good accuracy and precision.

Abstract
Triphasic waves are usually associated with metabolic encephalopathies but have been reported in patients with other etiologies. The pathophysiology of this EEG pattern remains poorly understood, although they have been attributed to lesion in the connections between the thalamus and cortex. We report a case of top-of-the-basilar artery occlusion with selective paramedian thalamic-mesencephalic infarct in which triphasic waves were evident on the EEG during clinical hypersomnia. To our knowledge this is the first reported case of triphasic waves with selective paramedian thalamomesencephalic infarct. We conclude that triphasic waves are a nonspecific manifestation of diencephalic dysfunction, probably of the paramedian thalamomesencephalic reticular system.

Abstract
Eleven newly-diagnosed GCA patients were included in a prospective open study and treated with high initial prednisone doses, a quick-tapering CS schedule and weekly oral MTX for two years. It took a mean of 14 weeks to reach a 10 mg/day dose of prednisone and 29.8 weeks until steroid withdrawal. The mean cumulative dose of prednisone was 3.4 g. Two patients relapsed and five developed CS side effects. No serious MTX side effects were observed. Our results suggest that MTX is safe and could be useful in the therapy of GCA.

Abstract
BACKGROUND The identification of the factors associated with infection of the surgical wound and the groups of patients with greatest risk of developing the same may aid in the elaboration of prevention strategies. METHODS A prospective follow up study of a group of 1,143 patients admitted to general and digestive surgical departments in the Ramón y Cajal Hospital over a period of 7 months was carried out to determine the accumulated incidence of infection of the surgical wound and quantify the associated risk factors. A mathematical model was developed by logistic multiple regression analysis allowing the identification of groups of patients with high risk of infection which were internally evaluated posteriorly. RESULTS Surgically intervened patients (70% of those admitted) developed a mean of 11 wound infections out of 100 patients. Five independent factors (age, surgical classification, length of intervention, presurgical stay, and presence of a central route) were associated to increased risk of infection. CONCLUSIONS The factors associated with surgical wound infection identified in this study are related to the degree of wound contamination, the intrinsic risk of the patients and quality of health care. The model obtained is more efficient than the traditional surgical classification for the identification of groups of patients with high risk of infection.

Abstract
Despite routine monitoring, a number of prolonged apneic and bradycardic episodes were undetected in a group of infants in the neonatal intensive care unit (NICU). Sixty-one infants were evaluated by 12-hour pneumocardiograms at a post-conceptional age of 35 +/- 3 (SD) weeks. Nursing documentation failed to detect 11 infants with prolonged apnea and bradycardia. Three of these infants were not detected in spite of increased awareness following in-service education. Such a lack of documentation may lead to improper medical management of infants at risk for pathologic apnea and suggests the need for more accurate documentation at the time of discharge.
