Assessment of pain relief after four botulinum toxin A injection cycles in patients with post-stroke lower limb spasticity: A prospective, observational study. Rehabilitacion (Madr) 2024; 58:100856. [PMID: 38795502 DOI: 10.1016/j.rh.2024.100856] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2023] [Revised: 02/06/2024] [Accepted: 04/27/2024] [Indexed: 05/28/2024]
Abstract
INTRODUCTION Spasticity is common after a stroke and is an independent risk factor for developing pain. BotulinumtoxinA injection is the treatment of choice for focal spasticity. We examined the effect of intramuscular botulinumtoxinA on pain relief in patients in routine clinical practice who were experiencing pain as a primary complaint associated with post-stroke lower limb spasticity. METHODS Prospective, multicentre, post-marketing observational study. The study period was 16 months. The primary effectiveness variable was the mean change from baseline on the pain 0-10 Numerical Rating Scale after four botulinumtoxinA injection cycles. Secondary endpoints included changes from baseline on the pain 0-100 Visual Analogue Scale, Goal Attainment Scale, modified Ashworth Scale, 10-Meter Walk Test, Penn Spasm Frequency Scale, and 36-item Short-Form Health Survey. RESULTS Of 186 enrolled patients, 180 (96.8%) received botulinumtoxinA at least once. The mean (standard deviation) pain 0-10 Numerical Rating Scale score decreased significantly (p<0.0001) from 4.9 (2.2) at baseline to 2.5 (2.1) at study end, representing a 50% decrease in pain severity. Relief of pain due to spasticity was supported by improvement from baseline in all secondary variables except the 10-Meter Walk Test. Two adverse events (erysipelas and phlebitis) in one patient were considered likely to be related to botulinumtoxinA injection. CONCLUSION BotulinumtoxinA appears to provide pain relief as an additional benefit of local treatment in patients with post-stroke lower limb spasticity for whom pain relief is a primary therapeutic goal (a Lay Abstract has been provided as Appendix A).

Antiretroviral treatment outcomes among late HIV presenters initiating treatment with integrase inhibitors or protease inhibitors. HIV Med 2020; 22:47-53. [PMID: 33047484 DOI: 10.1111/hiv.12962] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2020] [Revised: 07/08/2020] [Accepted: 08/26/2020] [Indexed: 11/29/2022]
Abstract
OBJECTIVES The aim of the study was to investigate the efficacy and safety of first-line antiretroviral therapy (ART) with integrase inhibitor (INI) or protease inhibitor (PI)-based regimens in patients with low CD4 cell counts and/or an AIDS-defining disease. METHODS We conducted a retrospective, multicentre analysis to investigate discontinuation proportions and virological response in patients with CD4 cell counts < 200 cells/µL and/or AIDS-defining disease when starting first-line ART. Proportions of those discontinuing ART were compared using univariate analysis. Virological response was analysed using the Food & Drug Administration (FDA) snapshot analysis (HIV-1 RNA < 50 HIV-1 RNA copies/mL at week 48). RESULTS Two hundred and eighteen late presenters were included in the study: 13.8% were women and 23.8% were of non-European ethnicity, and the mean baseline CD4 count was 91 cells/µL (standard deviation 112 cells/µL). A total of 131 late presenters started on INI- and 87 on PI-based treatment. It was found that 86.1% of patients treated with INIs and 81.1% of patients treated with PIs had a viral load < 50 copies/mL at week 48; proportions of discontinuation because of adverse events were 6.1% in the INI group and 11.5% in the PI group. No significant differences in discontinuation proportions were observed at week 12 or 48 between INI- and PI-based regimens (P = 0.76 and 0.52, respectively). Virological response was equally good in those receiving INIs and those receiving PIs (86.1% vs. 81.1%, respectively; P = 0.36). CONCLUSIONS In a European cohort of late presenters starting first-line INI or PI-based ART regimens, there were no significant differences in discontinuation proportions or virological response at week 48.

Abstract
PURPOSE The aim of the study was to evaluate the effectiveness of fentanyl pectin nasal spray (FPNS) in controlling procedural breakthrough cancer pain (BTCP) in advanced cancer patients undergoing radiotherapy. MATERIALS AND METHODS This study involved 62 advanced cancer patients, with well-controlled background pain, who presented BTCP associated to routine radiotherapy procedures, treated with FPNS according to our protocol of administration. The BPE intensity was measured using a visual analog scale (VAS). RESULTS The BTCP was triggered during the computed tomography simulation (79.3%) or treatment delivery (20.7%). Patients indicated a mean VAS of 8.8 (range 7-10) when attempting the procedure. After 4.5 min (range 2-10) of the first FPNS dose, the majority of patients (85.5%) indicated a VAS of 4.3 (range 2-6). 15.5% of the patients did not respond after 15 min; requiring a second dose. All these patients responded, reporting a mean VAS of 4.2 (range 4-6) after 3.0 min (range 2-5) of the second dose. None of the patients required a third dose, nor reported an AE after the administration of FPNS. CONCLUSIONS In our knowledge, our study is the one of highest recruitment, and with the fastest response of BTCP treated with FPNS reported in advanced cancer patients undergoing radiotherapy. FPNS has proven to be highly effective in reducing the intensity of procedural BTCP in a very short period of time.

Abstract
Aliquots of a wine of Merlot were micro-oxygenated at two doses of oxygen (2.5 and 5.0 mg of O2/L.month) in the presence or not of oak staves of different potential ellagitannin release (PER) for three months. In general, micro-oxygenation increased the color intensity and stability probably because favor the formation of new pigments. The presence of staves increased the total phenolic index and the ellagitannin concentration, and this effect was higher when greater was the PER of the staves. Finally, the dose of microoxygenation only affects the concentration of total furanic compounds whereas the PER of the staves seems to determine the concentration of furanic compounds, volatile phenols and β-methyl-γ-octolactones.

Abstract
INTRODUCTION Cerebral palsy describes a group of developmental and posture disorders, which cause a limitation of activity due to non-progressive damage occurring in the developing brain. A population register facilitates the identification of cerebral palsy cases within a specific geographic population. Its usefulness is recognized in the world literature but in Spain, published databases focus on the treatment or complications of cerebral palsy. AIMS To propose a population register that can be useful in different areas of our environment and to evaluate its validity through its application in two differentiated and geographically delimited health areas. SUBJECTS AND METHODS The registry consists of 124 items divided into seven sections: data on the child filiations, maternal history and parents' information, pregnancy and neonatal period data, diagnoses and classification, neuroimaging tests, therapeutic interventions and others. Patients attended in external consultations in Navarre and Andorra were included. RESULTS In the register, 53 patients (52.8% females) were evaluated. 56.5% were premature. Spastic cerebral palsy is the most frequent presentation. 42% have associated epilepsy. CONCLUSIONS The use of population registers allows a better knowledge of cerebral palsy as well as the evaluation and development of prevention strategies and optimization of care resources with objective data. It is necessary to generalize the use of this type of records in our environment.

A Quantitative Analysis of Cold Water for Human Consumption in Hospitals in Spain. JOURNAL OF HEALTHCARE ENGINEERING 2016; 2016:6534823.

Abstract
An estimation of the water used for human consumption in hospitals is essential to determine possible savings and to fix criteria to improve the design of new water consumption models. The present work reports on cold water for human consumption (CWHC) in hospitals in Spain and determines the possible savings. In the period of 2005-2012, 80 Eco-Management and Audit Schemes (EMAS) from 20 hospitals were analysed. The results conclude that the average annual consumption of CWHC is 1.59 m(3)/m(2) (with a standard deviation of 0.48 m(3)/m(2)), 195.85 m(3)/bed (standard deviation 70.07 m(3)/bed), or 53.69 m(3)/worker (standard deviation 16.64 m(3)/worker). The results demonstrate the possibility of saving 5,600,000 m(3) of water per year. Assuming the cost of water as approximately 1.22 €/m(3), annual savings are estimated as 6,832,000 €. Furthermore, 2,912 MWh of energy could be saved, and the emission of 22,400 annual tonnes of CO2 into the atmosphere could be avoided.

Abstract
It is commonly accepted that human immunodeficiency (HIV) coinfection negatively impacts on the rates of sustained virological response (SVR) to therapy with pegylated interferon plus ribavirin (PR). However, this hypothesis is derived from comparing different studies. The aim of this study was to determine the impact of HIV coinfection on SVR to PR in one single population. In a multicentric, prospective study conducted between 2000 and 2013, all previously naïve hepatitis C virus (HCV)-infected patients who started PR in five Spanish hospitals were analyzed. SVR was evaluated 24 weeks after the scheduled end of therapy. Of the 1046 patients included in this study, 413 (39%) were coinfected with HIV. Three hundred and forty-one (54%) HCV-monoinfected versus 174 (42%) HIV/HCV-coinfected patients achieved SVR (p < 0.001). The corresponding figures for undetectable HCV RNA at treatment week 4 were 86/181 (47%) versus 59/197 (30%), p < 0.001. SVR was observed in 149 (69%) HCV genotype 2/3-monoinfected subjects versus 91 (68%) HIV/HCV genotype 2/3-coinfected subjects (p = 0.785). In the HCV genotype 1/4-infected population, 188 (46%) monoinfected patients versus 82 (30%) with HIV coinfection (p < 0.001) achieved SVR. In this subgroup, absence of HIV coinfection was independently associated with higher SVR [adjusted odds ratio (95% confidence interval): 2.127 (1.135-3.988); p = 0.019] in a multivariate analysis adjusted for age, sex, baseline HCV RNA load, IL28B genotype, fibrosis stage, and type of pegylated interferon. HIV coinfection impacts on the rates of SVR to PR only in HCV genotype 1/4-infected patients, while it has no effect on SVR in the HCV genotype 2/3-infected subpopulation.

Abstract
OBJECTIVES The aim of the study was to establish the risk of liver toxicity in HIV/hepatitis C virus (HCV)-coinfected patients receiving etravirine, according to the degree of liver fibrosis. METHODS A prospective cohort study of 211 HIV-infected patients initiating an etravirine-containing regimen was carried out. HCV coinfection was defined as a positive HCV RNA test, and baseline liver fibrosis was assessed by transient elastography. Hepatotoxicity was defined as clinical symptoms, or an aspartate aminotransferase (AST) or alanine aminotransferase (ALT) value > 5-fold higher than the upper limit of normal if baseline values were normal, or 3.5-fold higher if values were altered at baseline. RESULTS Overall, 145 patients (69%) were HCV coinfected, with a lower nadir (165 versus 220 cells/μL, respectively; p = 0.03) and baseline (374 versus 498 cells/μL, respectively; p = 0.04) CD4 count than monoinfected patients. Etravirine was mainly used with two nucleoside reverse transcriptase inhibitors (129; 61%) or with a boosted protease inhibitor (PI) (28%), with no significant differences according to HCV serostatus. Transient elastography in 117 patients (81%) showed a median (range) stiffness value of 8.25 (3.5-69) kPa, with fibrosis stage 1 in 43 patients (37%) and fibrosis stage 4 in 28 patients (24%). During an accumulated follow-up time of 449.3 patient-years (median 548 days), only one patient with advanced fibrosis (50.8 kPa) had grade 3-4 liver toxicity (0.7%). Transaminases changed slightly, with no significant differences compared with baseline fibrosis, and nine and six patients had grade 1 and 2 transaminase increases, respectively. Also, HCV coinfection was not associated with a higher risk of discontinuation (25% discontinued versus 21% of monoinfected patients; p = 0.39, log-rank test) or virological failure (8% versus 12%, respectively; p = 0.4). CONCLUSIONS Our data suggest that etravirine is a safe option for HIV/HCV-coinfected patients, including those with significant liver fibrosis.

Abstract
To describe temporal trend and characteristics of newly HIV-diagnosed patients in a medical care area in Northwest Spain over the last 10 years. All newly diagnosed patients for HIV-infection from 2004 to 2013 at a reference medical care area in Northwest of Spain were identified. Epidemiological, virological, immunological, and clinical data, as well as HIV genotype and drug resistance information were recorded. A total of 565 newly HIV-diagnosed patients were identified. The number of new cases increased in the last 5 years (66 cases/year). Overall, 53.1% had a median CD4 counts < 350 cells/µl and 33.6% had an AIDS defining criteria. Non-B variants were found in 34.4% of patients being subtype F (25.8%) the most common non-B subtype. The rate of transmitted drug resistance (TDR) over the study period was 3.7%, but a decreased to 2.6% was observed in the last 5 years. The most prevalent TDR mutations were: T215 revertants (1.5%), K219QENR (1.2%), for NRTIs; K103N (1.9%), for NNRTIs; L90M (0.3%), for PIs. Overall, 73.2% of patients started antiretroviral treatment and 9.9% of patients died during follow-up. The number of newly HIV diagnosed patients increased since year 2009. There is a high prevalence of late diagnosis (53%) and 33% had an AIDS defining criteria. Interestingly, the most prevalent non-B subtype in our population was F (25.8%). These findings support the need to facilitate the access for HIV testing to reduce the rate of late HIV diagnosis, improve the clinical outcome and prevent HIV transmission.

Abstract
Local climatic factors might explain seasonal patterns of rotavirus infections, but few models have been proposed to determine the effects of weather conditions on rotavirus activity. Here, we study the association of meteorologic factors with rotavirus activity, as determined by the number of children hospitalized for rotavirus gastroenteritis on the Mediterranean island of Mallorca (Spain). We conducted a retrospective review of the medical records of children aged 0-5 years admitted for rotavirus gastroenteritis between January 2000 and December 2010. The number of rotavirus hospitalizations was correlated to temperature, humidity, rainfall, atmospheric pressure, water vapor pressure, wind speed, and solar radiation using regression and time-series techniques. A total of 311 patients were hospitalized for rotavirus gastroenteritis in the 11-year study period, with a seasonal pattern from December to June, and a peak incidence in February. After multiple regressions, weekly rotavirus activity could be explained in 82 % of cases (p < 0.001) with a one-week lag meteorologic model. Rotavirus activity was negatively associated to temperature and positively associated to atmospheric pressure, solar radiation, and wind speed. Temperature and solar radiation were the factors that contributed most to the model, with a peak rotavirus activity at 9 °C and 800 10KJ/m(2), respectively. In conclusion, hospitalization for rotavirus was strongly associated with mean temperature, but an association of rotavirus activity with solar radiation, atmospheric pressure, and wind speed was also demonstrated. This model predicted more than 80 % of rotavirus hospitalizations.

Abstract
Hypermutable or mutator microorganisms are those that have an increased spontaneous mutation rate as a result of defects in DNA repair or error avoidance systems. Over the last two decades, several studies have provided strong evidence for a relevant role of mutators in the evolution of natural bacterial populations, particularly in the field of infectious diseases. Among them, chronic respiratory infection with Pseudomonas aeruginosa in cystic fibrosis (CF) patients was the first natural environment to reveal the high prevalence and important role of mutators. A remarkable positive selection of mutators during the course of the chronic infection has been reported, mainly as a result of the emergence of DNA mismatch repair system (mutS, mutL or mutU)-deficient mutants, although strains defective in the GO system (mutM, mutY and mutT) have also been observed. High frequencies of mutators have also been noted among other pathogens in the CF setting, particularly Staphylococcus aureus and Haemophilus influenzae. Enhanced antimicrobial resistance development is the most thoroughly studied consequence of mutators in CF and other chronic infections, although recent studies show that mutators may additionally have important effects on the evolution of virulence, genetic adaptation to the airways of CF patients, persistence of colonization, transmissibility, and perhaps lung function decline. Further prospective clinical studies are nevertheless still needed for an in-depth evaluation of the impact of mutators on disease progression and outcome.

Abstract
OBJECTIVES We sought to evaluate the clinical use of linezolid for the treatment of neurosurgical infections. METHODS Retrospective observational study of a cohort of hospitalized patients who received linezolid for a culture-positive neurosurgical infection from July 2004 to February 2009 in a tertiary hospital in Spain. RESULTS Seventeen patients were included in the study. Main comorbidities among these patients included one or more of the following: subarachnoidal or intraventricular hemorrhage (n=8), solid neurological cancer (n=7), corticosteroids(n=9) and hydrocephalus (n=6). Eight patients underwent a craniotomy and fourteen patients had an external ventricular drainage (EVD) as predisposing factors for infection. Meningitis was the most common infection (11; 64.7%), followed by ventriculitis (4; 23.5%) and brain abscesses (2;11.8%). The main causative organisms were coagulase-negative Staphylococcus spp. (13; 76.5%). Linezolid was used as the initial therapy in 8 episodes, after therapy failure in 6 and for other reasons in 3. The oral route was used in 9 (52.9%) episodes; linezolid was initiated orally in 2 cases. The mean duration of treatment was 26.5 days (range 15-58). No adverse events were reported. Sixteen (94.1%) patients were considered cured.There was one recurrence. The mean length of hospital stay was 45.6 (range 15-112) days and the mean duration of follow-up was 7.2 (range 0.4-32) months. No related deaths occurred during active episodes. CONCLUSIONS Linezolid was mainly indicated in post-neurosurgical EVD-associated infections due to coagulase-negative Staphylococcus spp. It was used as initial therapy in most cases. A high rate of clinical cure was observed and no related adverse events were reported. More than half of the patients were benefited by the advantages of the oral route of administration.

Abstract
In this work, a fluid-solid interaction (FSI) analysis of a healthy and a stenotic human trachea was studied to evaluate flow patterns, wall stresses, and deformations under physiological and pathological conditions. The two analyzed tracheal geometries, which include the first bifurcation after the carina, were obtained from computed tomography images of healthy and diseased patients, respectively. A finite element-based commercial software code was used to perform the simulations. The tracheal wall was modeled as a fiber reinforced hyperelastic solid material in which the anisotropy due to the orientation of the fibers was introduced. Impedance-based pressure waveforms were computed using a method developed for the cardiovascular system, where the resistance of the respiratory system was calculated taking into account the entire bronchial tree, modeled as binary fractal network. Intratracheal flow patterns and tracheal wall deformation were analyzed under different scenarios. The simulations show the possibility of predicting, with FSI computations, flow and wall behavior for healthy and pathological tracheas. The computational modeling procedure presented herein can be a useful tool capable of evaluating quantities that cannot be assessed in vivo, such as wall stresses, pressure drop, and flow patterns, and to derive parameters that could help clinical decisions and improve surgical outcomes.

Abstract
Nowadays, interventions associated with the implantation of tracheal prostheses in patients with airway pathologies are very common. This surgery may promote problems such as migration of the prosthesis, development of granulation tissue at the edges of the stent with overgrowth of the tracheal lumen or accumulation of secretions inside the prosthesis. Among the movements that the trachea carries out, swallowing seems to have harmful consequences for the tracheal tissues surrounding the prosthesis. In this work, a finite-element-based tool is presented to construct patient-specific tracheal models, introducing the endotracheal prosthesis and analysing the mechanical consequences of this surgery during swallowing. A complete description of a patient-specific tracheal model is given, and a fully experimental characterization of the tracheal tissues is presented. To construct patient-specific grids, a mesh adaptation algorithm has been developed and the implantation of a tracheal prosthesis is simulated. The ascending deglutition movement of the trachea is recorded using real data from each specific patient from fluoroscopic images before and after implantation. The overall behaviour of the trachea is modified when a prosthesis is introduced. The presented tool has been particularized for two different patients (patient A and patient B), allowing prediction of the consequences of this kind of surgery. In particular, patient A had a decrease of almost 30 per cent in his ability to swallow, and an increase in stresses that were three times higher after prosthesis implantation. In contrast, patient B, who had a shorter trachea and who seemed to undergo more damaging effects, did not have a significant reduction in his ability to swallow and did not present an increase in stress in the tissues. In both cases, there are clinical studies that validate our results: namely, patient A underwent a further intervention whereas the outcome of patient B's surgery was completely successful. Notwithstanding the fact that there are a lot of uncertainties relating to the implantation of endotracheal prostheses, the present work gives a new insight into these procedures, predicting their mechanical consequences. This tool could be used in the future as pre-operative planning software to help thoracic surgeons in deciding the optimal prosthesis as well as its size and positioning.

Abstract
In previous work (E. E. Smith, D. G. Buckley, Z. Wu, C. Saenphimmachack, L. R. Hoffman, D. A. D'Argenio, S. I. Miller, B. W. Ramsey, D. P. Speert, S. M. Moskowitz, J. L. Burns, R. Kaul, and M. V. Olson, Proc. Natl. Acad. Sci. USA 103:8487-8492, 2006) it was shown that Pseudomonas aeruginosa undergoes intense genetic adaptation during chronic respiratory infection (CRI) in cystic fibrosis (CF) patients. We used the same collection of isolates to explore the role of hypermutation in this process, since one of the hallmarks of CRI is the high prevalence of DNA mismatch repair (MMR) system-deficient mutator strains. The presence of mutations in 34 genes (many of them positively linked to adaptation in CF patients) in the study collection of 90 P. aeruginosa isolates obtained longitudinally from 29 CF patients was not homogeneous; on the contrary, mutations were significantly concentrated in the mutator lineages, which represented 17% of the isolates (87% MMR deficient). While sequential nonmutator lineages acquired a median of only 0.25 mutation per year of infection, mutator lineages accumulated more than 3 mutations per year. On the whole-genome scale, data for the first fully sequenced late CF isolate, which was also shown to be an MMR-deficient mutator, also support these findings. Moreover, for the first time the predicted amplification of mutator populations due to hitchhiking with adaptive mutations in the course of natural human infections is clearly documented. Interestingly, increased accumulation of mutations in mutator lineages was not a consequence of overrepresentation of mutations in genes involved in antimicrobial resistance, the only adaptive trait linked so far to hypermutation in CF patients, demonstrating that hypermutation also plays a major role in P. aeruginosa genome evolution and adaptation during CRI.

Abstract
Clinical isolates (n = 389) of methicillin-resistant Staphylococcus aureus (MRSA) recovered from 371 patients between January 2003 and June 2004 at the three major public hospitals on the island of Majorca, Spain were studied. The clonal relatedness of MRSA isolates was determined by pulsed-field gel electrophoresis (PFGE) after digestion with SmaI. During the study period, MRSA was found in 31% of patients with S. aureus-positive cultures. PFGE analysis identified three predominant clones, affecting 94% of the patients. The three clones had been detected since 1999 in one hospital, and were designated as clones A, B and C. Whereas clones A and B (multidrug-resistant) were related to the two most prevalent clones in Spain at this time, clone C was identical to EMRSA-15, currently one of the most common MRSA clones in UK hospitals and also detected in other countries, but rarely in Spanish hospitals. This imported epidemic clone was detected in c. 10% of patients admitted to one of the three hospitals in 2002, but its prevalence has increased significantly (32% of the patients investigated in the three hospitals in the present study), and this clone also accounted for 44% of the isolates from non-hospitalised patients. Even though EMRSA-15 showed the least multidrug resistance of the three major clones, it was apparently more virulent, since it was associated significantly (p 0.001) with bacteraemia, and positive blood cultures were documented for 21% of the patients infected by this clone, compared with only 10% and 7% of patients infected with clones A and B, respectively.

Abstract
18613 Background: Anorexia is a common and major problem in cancer patients. Its ethiology is multifactorial and has negative effects on pts QoL. Up to 30% of non-metastasic lung cancer pts receiving radiotherapy will develop anorexia during treatment. We conducted a randomized trial comparing the efficacy of two different doses of MA. The results of the first 130 pts included, presented at ASCO 2003, indicated that MA at doses of 600 mg/day is significantly more effective in the treatment of anorexia in these pts than low doses (320 mg/day) of MA. Here we present the results of the quality of life sub-study which purpose is to evaluate the effect of reversing anorexia in pts health related quality of life (HRQOL). Methods: From February 1999 to April 2003, 160 non-mestastatic lung cancer pts who developed anorexia during radiotherapy were randomized to receive either 320 mg/day or 600 mg/day of MA. All pts who developed anorexia filled up the EuroQuol (EQ-5D) quality of life questionnaire before treated with MA and the responders did it again when appetite was regained. The endpoint was improvement in pts HRQOL (defined as an increase > 5 mm in the EQVAS score between the second and first questionnaires). Results: The analysis of the EuroQuol (EQ-5D) questionnaires of the 131 pts who responded to treatment with MA shows that 106 pts (81%) had an improvement > 5 mm in the EQVAS score while 19 % did not. The difference is statistically significant (Binomial test: p < 0.0001). Regarding differences between the two series, 42 pts improved in the 320 mg arm versus 64 in the 600 mg arm which is not statistically significant (Fisher test: p = 0.501). Conclusions: Our results indicate that reversal of anorexia with MA has a clinically significant improvement in HRQOL in non-metastatic lung cancer pts undergoing radiation therapy. The absence of statistically significant differences between the two series may be due to the sample size. [Table: see text] No significant financial relationships to disclose.

Abstract
Stimulation of the innate immune system is potentially very important in neonates who have an immature adaptive immune system and vaccination cannot be used to reduce the risk of infection. CpG oligodeoxynucleotide (ODN) can stimulate innate immune responses in newborn chickens and mice, but similar studies are lacking in other mammalian species. We have shown previously that CpG ODN can both stimulate an acute-phase immune response and induce the antiviral effector molecule, 2'5'-A synthetase, in adult sheep. Therefore, the immunostimulatory activity of A class and B class CpG ODN was evaluated in newborn lambs, and the capacity of CpG ODN-induced responses to reduce viral shedding was evaluated following aerosol challenge with the respiratory pathogen, bovine herpesvirus-1 (BHV-1). In vitro CpG ODN stimulation of peripheral blood mononuclear cells (PBMC) isolated from newborn lambs (3-5 days old) and adult sheep induced equivalent CpG-specific proliferative responses and interferon-alpha (IFN-alpha) secretion. CpG ODN-induced IFN-alpha secretion by neonatal PBMCs was, however, significantly (p < 0.01) enhanced 6 days after subcutaneous (s.c.) injection of 100 microg/kg CpG ODN 2007. Newborn lambs injected s.c. with B class CpG ODN 2007 or the inverted GpC control ODN formulated in 30% Emulsigen (MVP Laboratories, Ralston, NE) displayed CpG ODN-specific increases in body temperature (p < 0.0001), serum 2'5'-A synthetase activity (p = 0.0015), and serum haptoglobin (p = 0.07). CpG ODN-treated lambs also displayed a transient reduction in viral shedding on day 2 postinfection (p < 0.05), which correlated (p < 0.03) with serum 2'5'-A synthetase levels on the day of viral challenge. These observations confirmed that CpG ODNs effectively activate innate immune responses in newborn lambs and CpG ODN-induced antiviral responses correlated with a reduction in viral shedding.

Abstract
INTRODUCTION Disability produced by locomotor pathology causes a loss in working hours and indirect costs that are increasing at a growing rate. The aims of this study are to estimate the costs in total working hours lost caused by this pathology in two health areas of Navarra with 441,600 inhabitants, to obtain standards for the duration and incidence of sick leave and to study the relation between the average duration of sick leave and variables such as the geographical accessibility of the rehabilitation services, residence in a rural or urban milieu, and between the different health areas. METHODS We study all the processes of temporary disability due to pathology of the locomotor system in Health Areas I and III of Navarra in 1997 and 1998, taking different variables into account. We make a descriptive study of the pathologies, counting the working days lost. We calculate the annual incidence of sick leave because of pathologies. We compare average duration with other variables. RESULTS These represent 221,054 lost working days per year. Low back pain and sprained ankles are the most frequent processes. We find an increase in the incidence of temporary disability due to low back pain and lumbar/sciatica in the basic rural areas of the middle region. There are no statistically significant differences with a p<0.05 in the duration of temporary disability according to Health Area, rural or urban milieu or geographical accessibility to the Rehabilitation Services. A statistically significant fall can be observed in the first year of operation of a temporary disability management program.

Abstract
Cytosine-phosphate-guanosine (CpG)-DNA can induce an impressive array of innate immune responses that may directly or indirectly contribute to the clearance of infectious agents. Assays, such as lymphocyte proliferative responses, have been used to demonstrate that the immunostimulatory activity of CpG-DNA is conserved among a broad range of vertebrate species, but no studies have been completed to determine if qualitative differences exist among species for CpG-oligodeoxynucleotide (ODN)-induced innate immune responses. In this study, we assessed the capacity of a Class A (ODN 2216) and a Class B (ODN 2007) CpG-ODN to induce innate immune responses in two closely related species, ovine (n = 28) and bovine (n = 29). The secretion of interferon (IFN)-alpha and IFN-gamma and non-major histocompatability complex (MHC)-restricted cytotoxic activity were assayed with CpG-ODN-stimulated peripheral blood mononuclear cells (PBMC). These investigations revealed significant interspecies and intraspecies variation in the responses. As expected, ODN 2216 was a potent inducer of IFN-alpha secretion by both bovine and ovine PBMC, but ODN 2007 also induced dose-dependent, CpG-specific IFN-alpha secretion by ovine PBMC. In contrast, a significant dose-dependent, CpG-specific IFN-gamma secretion response was only observed following ODN 2216 stimulation of bovine PBMC. Furthermore, both ODN 2216 and ODN 2007 induced CpG-specific non-MHC-restricted cytotoxicity with ovine but not bovine PBMC. Finally, there was not a single assay in which PBMC from all sheep or cattle responded at a detectable level. A striking aspect of these results is that such marked differences in CpG-ODN induced innate responses existed both between and within two closely related species.
