Abstract
OBJECTIVE To describe efficacy, safety, and patient-reported outcomes (PROs) in patients with rheumatoid arthritis (RA) with an inadequate response to conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) treated with tofacitinib or biological DMARDs (bDMARDs) in real-life conditions. METHODS A noninterventional study was performed between March 2017 and September 2019 at 13 sites in Colombia and Peru. Outcomes measured at baseline and at the 6-month follow-up were disease activity (RAPID3 [Routine Assessment of Patients Index Data] score), functional status (HAQ-DI [Health Assessment Questionnaire] score), and quality of life (EQ-5D-3L [EuroQol Questionnaire]). The Disease Activity Score-28 (DAS28-ESR) and frequency of adverse events (AEs) were also reported. Unadjusted and adjusted differences from baseline were estimated and expressed as the least squares mean difference (LSMD). RESULTS Data from 100 patients treated with tofacitinib and 70 patients with bDMARDs were collected. At baseline, the patients' mean age was 53.53 years (SD 13.77), the mean disease duration was 6.31 years (SD 7.01). The change from baseline at month 6 was not statistically significant different in the adjusted LSMD [SD] for tofacitinib vs. bDMARDs for RAPID3 score (-2.55[.30] vs. -2.52[.26]), HAQ-DI score (-.56[.07] vs. -.50[.08]), EQ-5D-3L score (.39[.04] vs. .37[.04]) and DAS28-ESR (-2.37[.22] vs. -2.77[.20]). Patients from both groups presented similar proportions of nonserious and serious AEs. No deaths were reported. CONCLUSION Changes from baseline were not statistically significantly different between tofacitinib and bDMARDs in terms of RAPID3 scores and secondary outcomes. Patients from both groups presented similar proportions of nonserious and serious AEs. CLINICAL TRIAL NUMBER NCT03073109.

Abstract
OBJECTIVE To evaluate work productivity of adult Latin American patients with rheumatoid arthritis (RA) treated with tofacitinib and biological disease-modifying anti-rheumatic drugs (bDMARDs) measured by the Work Productivity and Activity Impairment (WPAI) in RA questionnaire at 0- and 6-month follow-up. METHODS This non-interventional study was performed in Colombia and Peru. Evaluated the effects of tofacitinib and bDMARDs in patients with RA after failure of conventional DMARDs. The WPAI-RA questionnaire was administered at baseline and at the 6-month (±1 month) follow-up. The results are expressed as least squares means (LSMs), and standard errors (SEs). RESULTS One hundred patients treated with tofacitinib and 70 patients treated with bDMARDs were recruited. Twenty-eight percent of patients from the tofacitinib group and 40.0% from the bDMARDs group were working for pay at baseline. At month 6, the changes in absenteeism, presenteeism, and work impairment due to health were -18.3% (SE 7.7), -34.8% (SE 5.9), and -11.0% (SE 16.5), respectively, in the tofacitinib group and -19.4% (SE 8.0), -34.8% (SE 6.2), and -15.9% (SE 15.0), for the bDMARD group. CONCLUSION For patients who reported working, there were improvements in presenteeism, absenteeism, and work impairment due to health in both groups. TRIAL REGISTRATION NCT03073109.

Abstract
A bifunctional amine/squaramide catalyst promoted direct aldol addition of an hydantoin surrogate to pyridine 2-carbaldehyde N-oxides to afford adducts bearing two vicinal tertiary/quaternary carbons in high diastereo- and enantioselectivity (d.r. up to >20:1; ee up to 98 %) is reported. Acid hydrolysis of adducts followed by reduction of the N-oxide group yields enantiopure carbinol-tethered quaternary hydantoin-azaarene conjugates with densely functionalized skeletons. DFT studies of the potential energy surface (B3LYP/6-31+G(d)+CPCM (dichloromethane)) of the reaction correlate the activity of different catalysts and support an intramolecular hydrogen-bond-assisted activation of the squaramide moiety in the transition state of the catalytic reaction.

Abstract
Atherosclerotic stenosis of the posterior circulation refractory to medical treatment generally has a poor prognosis resulting in a high morbidity-mortality rate and the recurrence of ischemic events. Extracranial bypass in the vertebrobasilar system is possible but is also associated with high morbidity (3–21%) and mortality (13–55%)1,2, and has not been demonstrated to reduce the risk of stroke. Percutaneous angioplasty alone has also not shown favorable results, and further, has been associated with a remarkable number of complications. The improvement resulting from endovascular therapy has taken the treatment of this pathology to a new dimension. We describe eight patients with severe symptomatic basilar artery stenosis who, in addition to medical therapy, were treated by our service with angioplasty and stent placement. Three of them received urgent treatment. All patients suffering from severe stenosis of the basilar artery were treated by the insertion of balloon expandable stents. The degree of pre-stent stenosis was approximately 80% in all cases, and was reduced to 5–10% after the stent implant. There were no complications during treatment. There has not been a recurrence of symptoms or a new ischemic lesion during the one-year follow-up period. Endovascular therapy with a balloon expandable stent or angioplasty plus stent are presented as improved choices for treatment of patients with severe basilar artery stenosis refractory to medical treatment.

Abstract
The tomato borer Tuta absoluta Meyrick is a serious tomato pest that has lately undergone a rapid expansion, causing severe crop losses. An integrated management is required to control this insect, within which biological control is now beginning to play a key role. In this regard, the effectiveness of a liquid formulation based on strains of the fungus Metarhizium anisopliae variety anisopliae (Metschnikoff) Sorokin (4.46 x 10(9) viable conidia per milliliter), applied together with irrigation water, has been evaluated by laboratory tests on different populations of T. absoluta. A bioassay method has been developed to test the efficacy of the product. The technique chosen has been validated and the different studied populations have been typified according to their susceptibility, determining the baseline susceptibility of the pest to the fungus. The results revealed a complete efficacy of M. anisopliae against pupae of T. absoluta at the recommended label rate (5.58 x 10(9) viable conidia per liter) for the populations assayed. Moreover, a notably lower dose was also sufficiently effective to control the tomato borer populations because values of LC90 lower than 3 x 10(9) viable conidia per liter were obtained unfailingly. The most sensitive populations were those collected in Almeria and Nijar, Spain, with LC50 values of 0.21 and 0.22 x 10(9) viable conidia per liter(-1), respectively. The average value obtained for LC50 was 0.34 x 10(9) viable conidia per liter(-1) and 2 x 10(9) for LC90. These results show the potential of M. anisopliae to control pupae of the tomato borer in integrated pest management programs.

Abstract
Elastofibroma dorsi is a benign lesion of fibroelastic tissue. It often presents bilaterally, is frequently localized to the subscapular region, and is more common in middle-aged and elderly women. The pathogenesis is still unclear but it has been suggested to involve reactive, degenerative, or neoplastic processes. We present a retrospective study of the findings from 6 patients with elastofibroma dorsi. Elastofibroma should be included in the differential diagnosis of subcutaneous scapular tumors, as it is a benign lesion that only requires surgery when associated with symptoms or the lesion is extensive. Noninvasive techniques such as ultrasonography, computed tomography, and, above all, magnetic resonance imaging, may be sufficient to guide diagnosis. The results of histology and imaging are closely correlated, so the need for unnecessary biopsy and surgery may be avoided.

Abstract
The electron internal transport barrier (eITB) formation in the Large Helical Device (LHD) is studied with the transport code TOTAL and a GyroBohm-like model. The reduction of anomalous transport by the E x B shear has been introduced by means of the factor [1 + (tauomega(ExB))(gamma)](-1). Simulation results show a clear critical transition between plasma regimes with rather flat electron temperature profiles (non-) to a steeped one (with eITB) when average density is low enough. With the aim of studying the eITB formation as a phase transition phenomenon, the electron average density is taken as the control parameter and the E x B shearing rate as the order parameter. Results show how the eITB formation in LHD is compatible with a continuum phase transition with critical exponent beta = 0.40.

Abstract
BACKGROUND Spirometric parameters can be normal in many stable asthma patients, making a diagnosis difficult at certain times in the course of disease. OBJECTIVES The present study aims to find differences and similarities in the acoustic characteristics of forced wheezes among asthma patients with and without normal spirometric values. METHODS Eleven chronic asthma patients (8 men/3 women) with moderate-to-severe airway obstruction (FEV1 48.4%), 9 stable asthma patients (6 males/3 females) with normal spirometry (FEV1 84.0%) and a positive methacholine test and 14 healthy subjects (8/6) were enrolled in the study. A contact sensor was placed on the trachea, and wheezes were detected by a modified Shabtai-Musih algorithm in a time-frequency representation. RESULTS More wheezes were recorded in obstructive asthma patients than in stable asthma and control subjects: nonstable asthma 13.6 (13.3), stable asthma 3.5 (3.0) and control subjects 2.5 (2.1). The mean frequency of all wheezes detected was higher in control subjects than in either stable or non-stable asthma patients. The change in the total number of wheezes after terbutaline inhalation was more pronounced in nonstable asthma patients than in stable asthmatics and control subjects. CONCLUSIONS This study confirms that wheeze recording during forced expiratory maneuvers can be a complementary measure to spirometry to identify asthma patients.

Abstract
Stenoses in the posterior cerebral circulation often have a bad prognosis. There may be a high rate of morbi-mortality and recurrences of ischemic events in this territory. Currently we have no evidence or consensus about what the best pharmacological option is for these patients. We report a case of a 75 year old woman with sever stenosis of the proximal part of the basilar artery with recurrent transient ischemic events unresponsive to different combinations of antiagregant and anticoagulant treatments. A percutaneous transluminal angioplasty with the addition of a stent in the basilar artery was performed successfully. At present, there are few studies and a low number of patients treated by this technique. The results obtained are promising, with a low rate of morbi-mortality, the most frequent complications being embolization of the atherosclerotic lesion, dissection, rupture or restenosis.

Abstract
BACKGROUND Exacerbations of chronic obstructive pulmonary disease (COPD) are a leading cause of admission to hospital among men in many countries, although the factors causing exacerbations are largely unknown. The association between readmission for a COPD exacerbation and a wide range of modifiable potential risk factors, after adjusting for sociodemographic and clinical factors, has been assessed. METHODS Three hundred and forty patients with COPD recruited during an admission for an exacerbation in four tertiary hospitals in the Barcelona area of Spain were followed for a mean period of 1.1 years. Information on potential risk factors, including clinical and functional status, medical care and prescriptions, medication adherence, lifestyle, health status, and social support, was collected at the recruitment admission. A Cox's proportional hazards model was used to obtain independent relative risks of readmission for COPD. RESULTS During the follow up period 63% of patients were readmitted at least once, and 29% died. The final multivariate model showed the following risk (or protective) factors: > or =3 admissions for COPD in the year before recruitment (hazard ratio (HR)=1.66, 95% CI 1.16 to 2.39), forced expiratory volume in 1 second (FEV(1)) percentage predicted (0.97, 95% CI 0.96 to 0.99), oxygen tension (0.88, 95% CI 0.79 to 0.98), higher levels of usual physical activity (0.54, 95% CI 0.34 to 0.86), and taking anticholinergic drugs (1.81, 95% 1.11 to 2.94). Exposure to passive smoking was also related to an increased risk of readmission with COPD after adjustment for clinical factors (1.63, 95% CI 1.04 to 2.57) but did not remain in the final model. CONCLUSIONS This is the first study to show a strong association between usual physical activity and reduced risk of readmission to hospital with COPD, which is potentially relevant for rehabilitation and other therapeutic strategies.

Abstract
BACKGROUND The evaluation of respiratory muscle performance can be described in terms of strength and endurance, the latter usually being measured by means of resistive or threshold inspiratory loads, using devices that are also used for respiratory muscle training. Few authors, however, have published endurance reference values for healthy subjects. To that end, we studied two indices of respiratory muscle endurance in a population of 99 healthy volunteers (50 men, 49 women) divided into five age groups (20-70 years old) applying a modification of the methods of Martyn et al. and Nickerson and Keens. Inspiratory muscle endurance (Tlim) was defined as the time the subject was able to sustain breathing against an inspiratory pressure load equivalent to 80% of the maximum tolerated load (Cmax). Cmax was calculated using a 2-min incremental threshold load. RESULTS We found that the heaviest inspiratory threshold load tolerated for 2 min and the time a load equivalent to 80% of Cmax (Tlim) could be sustained were not significantly different for male and female subjects. Tlim correlated with Cmax, age, height, and maximum respiratory pressures.

Abstract
The four primary objectives of this descriptive study were to: 1) design a quality-measurement instrument for institutional cancer registries (ICRs), 2) evaluate the existing ICRs in Colombia with the designed instrument, 3) categorize the different registries according to their quality and prioritize efforts that will efficiently promote better registries with the limited resources available, and 4) determine the institution with the greatest likelihood of successfully establishing Colombia's second population-based cancer registry. In 1990 the National Cancer Institute of Colombia developed 13 institution-based cancer registries in different Colombian cities in order to promote the collection of data from a large group of cancer diagnostic and treatment centers. During the first half of 1997, this evaluation reviewed 12 registries; one of the original 13 no longer existed. All of the Colombian institutions (hospitals) that maintain institution-based cancer registries were included in the study. At each institution, a brief survey was administered to the hospital director, the registry coordinator, and the registrar (data manager). Researchers investigated the institutions by looking at six domains that are in standard use internationally. Within each domain, questions were developed and selected through the Delphi method. Each domain and each question were assigned weights through a consensus process. In most cases, two interviewers went to each site to collect the information. The university hospitals in Cali, Pereira, and Medellín had substantially higher scores, reflecting a good level of performance. Four of the 12 institutions had almost no cancer registry work going on. Five of the 12 hospital directors considered that the information provided by the cancer registries influenced their administrative decisions. Three of the registries had patient survival data. Four of the institutions allocated specific resources to operate their cancer registries; in the other 8 hospitals there was no clear budget allocation. Seven of the hospital directors could not identify five or more objectives of a cancer registry. Data management was usually poor and resources insufficient at most of the institutions. In summary, the cancer registry system in Colombia varies greatly from institution to institution. A few of the hospitals do a good job while others have neglected the registries. The high, identical total scores for Pereira and Medellín suggest they would be good locations to establish new population-based cancer registries similar to the existing one in Cali. However, the overall characteristics in Pereira may provide a more appropriate environment for the second registry, with Medellín as an alternative.

Abstract
PURPOSE During the past 10 years, the acoustic analysis of breath sounds has been used as a diagnostic tool in patients suffering from obstructive respiratory diseases. Acoustic analysis might be able to monitor the response to bronchodilator therapy in a clinical setting. So far, few studies have been carried out in asthmatic patients. To assess the responses of a sampling of asthma patients to an inhaled bronchodilator (terbutaline) by means of spectral analysis of the tracheal sound performed during forced expiratory maneuvers. MATERIAL AND METHODS Seventeen nonsmoking asthma patients (9 were male, 8 were female) who had been suffering from the disease for > or = 15 years were included in the study, as were 15 normal subjects (7 were male, 8 were female). The average age (+/- SD) was 56.5 +/- 15.2 years (FVC, 2.7 +/- 0.9 L [63.4%]; FEV1, 1.5 +/- 0.6 L [53.0%]). The tracheal sounds were collected during three forced expiratory maneuvers with a sampling frequency of 5,000 Hz and were analyzed by applying a 16-parameter autoregressive model. RESULTS The centroid frequency decreased after the bronchodilator was given at different flow segments between 1.2 and 0.4 L/s, with significant changes between 0.6 and 0.4 L/s. CONCLUSIONS Patients with asthma showed changes in the spectral acoustic analysis frequencies after the administration of a bronchodilator drug (terbutaline) during forced expiratory maneuvers.

Abstract
Risk factors and prevalence of occupational asthma in the general population were examined in a cross-sectional community study conducted in north Barcelona. A self-administered questionnaire that contained questions about bronchial asthma and occupation was mailed to a random sample of 4000 adults who lived in north Barcelona; the response rate was 31.0%. Investigators made phone calls to nonresponders to determine response bias. Risk factors for occupational asthma were assessed with logistic regression. Investigators, who sought a definite diagnosis of occupational asthma, offered a chest examination to all subjects who reported asthma in life and who experienced clinically relevant occupational exposures. The examination included skin tests to common allergens, forced spirometry with reversibility test, and peak expiratory flow rate at and away from work. Cumulative prevalences obtained from responders were good estimates for the general population: asthma in life, 9.0%; clinically relevant occupational exposure, 28.9%; and respiratory symptoms at work, 18.3%. Adjustments were made for age, sex, and smoking habits, and relevant exposure caused an increase in asthma risk (odds ratio [OR] = 1.9; 95% confidence interval [95% CI] = 1.1, 3.2); however, when investigators introduced specific occupations in the model as independent variables, only occupational exposure to leather (OR = 12.8 [95% CI = 4.4, 37.4]), animals (OR = 10.3 [95% CI = 1.6, 65.2]), dyes (OR = 5.6 [95% CI = 2.1, 15.3]), and flour (OR = 4.6 [CI = 1.3, 15.7]) persisted as significant risk factors. A 1.7/1000 minimum prevalence of occupational asthma for the north Barcelona population was estimated from chest examination results. Occupational risk for asthma appeared to be associated with exposure to leather, animals, dyes, or flour in the north Barcelona area.

Abstract
UNLABELLED Chronic obstructive pulmonary disease (COPD) patients suffer from significant impairment in quality of life (QL), but the variables related to this impairment are not well known. The aim of this study has been to identify physiological parameters related to QL in severe COPD patients undergoing long-term oxygen therapy. MATERIALS AND METHODS We studied 47 COPD patients using long-term oxygen therapy (43 men/four women, 65.17 SD 8.21 years, 3.17 SD 2.61 years on oxygen). The Nottingham Health Profile (NHP) and activities of daily living (ADL) questionnaire were used to measure QL. Subjective assessment of dyspnoea was performed using a visual analogue scale. The physiological parameters determined were lung function (spirometry, arterial blood gases, lung volumes and carbon monoxide diffusing capacity), muscle function (maximum inspiratory and expiratory pressures, deltoid muscle and handgrip strength), and nutrition status (tricipital skin fold and mid-arm muscle circumference). RESULTS High ADL (8.32 SD 6.97) and NHP scores (energy 63.3 SD 40.43, pain 35.11 SD 31.56, emotional reactions 43.03 SD 25.13, sleep 51.91 SD 32.75, social isolation 30.64 SD 26.98, physical mobility 49.73 SD 24.93) demonstrated clinically significant QL impairment in the severe COPD patients studied. Stepwise multiple regression analysis found a correlation between lung function and QL. Low FEV1% was associated with impairment in energy, physical mobility and social isolation NHP scores and ADL score (r = -0.3, P < 0.05). RV/TLC also correlated with ADL and social isolation scores (r = 0.3, P < 0.05). Lung function explained 39-45% of the variation in these QL dimensions. QL did not correlate with other lung function parameters, muscle function or nutrition status. CONCLUSION COPD patients using long-term oxygen suffer from severe QL impairment affecting not only energy and mobility but also emotional reactions, social isolation and sleep. Lung function is related to energy, mobility and social isolation dimensions, but muscle function is unrelated to QL in these patients.

Abstract
Investigations of pharmacodynamic parameters (postantibiotic effect [PAE], sub-MIC effects [SMEs], etc.) have been progressively employed for the design of dosing schedules of antimicrobial agents. However, there are fewer in vivo than in vitro data, probably because of the simplicity of the in vitro procedures. In this study, we have investigated the in vitro PAE, SME, and previously treated (postantibiotic [PA]) SME (1/2 MIC, 1/4 MIC and 1/8 MIC) of azithromycin and isepamicin against standard strains of Staphylococcus aureus and Escherichia coli by using centrifugation to remove the antibiotics. In addition, the in vivo PAE and SME have been studied with the thigh infection model in neutropenic mice. Finally, in vivo killing curves with two dosing schedules were determined to examine whether the PAE can cover the time that antimicrobial agents are below the MIC. The two antimicrobial agents induced moderate-to-high in vitro PAEs, SMEs, and PA SMEs against S. aureus (>8 h) and E. coli (3.38 to >7.64 h). The in vivo PAEs were also high (from 3.0 to 3.6 h), despite the fact that isepamicin had lower times above the MIC in serum. Only azithromycin showed a high in vivo SME against the two strains (1.22 and 1.75 h), which indicated that the in vivo PAEs were possibly overestimated. In the killing kinetics, no great differences (<0.5 log10) were observed between the schedule that took the PAE into account and the continuous administration of doses. These results are comparable with those of other authors and suggest that these antimicrobial agents could be administered at longer intervals without losing effectiveness.

Abstract
This study has investigated the effect of interrupting nasal continuous positive airway pressure (nCPAP) therapy on 10 obstructive sleep apnoea (OSA) patients (nine male, one female) (53.6 +/- 7.3 years) treated over 2 years. The effect of nCPAP interruption was determined by variations in sleep counts and gasometric values during five consecutive nights. On the first night, the patient used his habitual nCPAP. On the remaining nights, nasal nCPAP was not applied. The apnoea-hypopnoea index (AHI) was found to increase significantly in the second night, attaining a similar level to that of the basal study (2 years ago). SaO2 minimum decreased and PaCO2 increased in the second night with respect to the first night. The interruption of nCPAP therapy in OSA patients treated over a long period of time increases the sleep counts and impairs the gasometric parameters. Consequently, any change in nCPAP time therapy must be checked to avoid negative effects.
