Abstract
Idiopathic pulmonary fibrosis (IPF) is a fibrotic age-related chronic lung disease characterized by the accumulation of senescent cells. Whether impaired immune response is responsible for the accumulation of senescent cells in the IPF lung remains unknown. In this study, we characterized the NK phenotype in IPF lungs via flow cytometry using 5-dodecanoylaminofluorescein di-β-d-galactopyranoside, markers of tissue residence, and chemokine receptors. The effect of the lung microenvironment was evaluated using lung fibroblast (LF) conditioned media (CM), and the bleomycin-induced pulmonary fibrosis mouse model was used to assess the in vivo relationship between NK cells and the accumulation of senescent cells. We found that NK cells from the lower lobe of IPF patients exhibited immune-senescent and impaired CD57-NKG2A+ phenotype. We also observed that culture of NK cells from healthy donors in CM from IPF lower lobe lung fibroblasts induced a senescent-like phenotype and impaired cytotoxic capacity. There is an impaired NK recruitment by LF, and NKs presented decreased migration toward their CM. In addition, NK cell-depleted mice treated with bleomycin showed increased collagen deposition and accumulation of different populations of senescent cells compared with controls. The IPF lung microenvironment induces a dysfunctional NK phenotype limiting the clearance of lung senescent cells and the resolution of lung fibrosis. We propose that impaired NK activity could be one of the mechanisms responsible for perpetuating the accumulation of senescent cells in IPF lungs.

Abstract
BACKGROUND The role of the immune system in the pathobiology of Idiopathic Pulmonary Fibrosis (IPF) is controversial. METHODS To investigate it, we calculated immune signatures with Gene Set Variation Analysis (GSVA) and applied them to the lung transcriptome followed by unbiased cluster analysis of GSVA immune-enrichment scores, in 109 IPF patients from the Lung Tissue Research Consortium (LTRC). Results were validated experimentally using cell-based methods (flow cytometry) in lung tissue of IPF patients from the University of Pittsburgh (n = 26). Finally, differential gene expression and hypergeometric test were used to explore non-immune differences between clusters. RESULTS We identified two clusters (C#1 and C#2) of IPF patients of similar size in the LTRC dataset. C#1 included 58 patients (53%) with enrichment in GSVA immune signatures, particularly cytotoxic and memory T cells signatures, whereas C#2 included 51 patients (47%) with an overall lower expression of GSVA immune signatures (results were validated by flow cytometry with similar unbiased clustering generation). Differential gene expression between clusters identified differences in cilium, epithelial and secretory cell genes, all of them showing an inverse correlation with the immune response signatures. Notably, both clusters showed distinct features despite clinical similarities. CONCLUSIONS In end-stage IPF lung tissue, we identified two clusters of patients with very different levels of immune signatures and gene expression but with similar clinical characteristics. Weather these immune clusters differentiate diverse disease trajectories remains unexplored.

Abstract
(1) The role of the immune response in the pathogenesis of idiopathic pulmonary fibrosis (IPF) remains controversial. We hypothesized that peripheral blood immune phenotypes will be different in IPF patients and may relate to the disease severity and progression. (2) Whole blood flow cytometry staining was performed at diagnosis in 32 IPF patients, and in 32 age- and smoking-matched healthy controls. Thirty-one IPF patients were followed up for one year and categorized as stable or progressors based on lung function, deterioration and/or death. At 18-60 months, immunophenotypes were characterized again. (3) The main results showed that: (1) compared to matched controls, at diagnosis, patients with IPF showed more neutrophils, CD8+HLA-DR+ and CD8+CD28- T cells, and fewer B lymphocytes and naïve T cells; (2) in IPF, circulating neutrophils, eosinophils and naïve T cells were associated with lung function abnormalities; (3) patients whose disease progressed during the 12 months of follow-up showed evidence of cytotoxic dysregulation, with increased CD8+CD28- T cells, decreased naïve T cells and an inverted CD4/CD8 ratio at baseline; and (4) blood cell alterations were stable over time in survivors. (4) IPF is associated with abnormalities in circulating immune cells, particularly in the cytotoxic cell domain. Patients with progressive IPF, despite antifibrotic therapy, present an over-activated and exhausted immunophenotype at diagnosis, which is maintained over time.

Abstract
BACKGROUND Idiopathic Pulmonary Fibrosis (IPF) is an age-associated progressive lung disease with accumulation of scar tissue impairing gas exchange. Previous high-throughput studies elucidated the role of cellular heterogeneity and molecular pathways in advanced disease. However, critical pathogenic pathways occurring in the transition of fibroblasts from normal to profibrotic have been largely overlooked. METHODS We used single cell transcriptomics (scRNA-seq) from lungs of healthy controls and IPF patients (lower and upper lobes). We identified fibroblast subclusters, genes and pathways associated with early disease. Immunofluorescence assays validated the role of MOXD1 early in fibrosis. RESULTS We identified four distinct fibroblast subgroups, including one marking the normal-to-profibrotic state transition. Our results show for the first time that global downregulation of ribosomal proteins and significant upregulation of the majority of copper-binding proteins, including MOXD1, mark the IPF transition. We find no significant differences in gene expression in IPF upper and lower lobe samples, which were selected to have low and high degree of fibrosis, respectively. CONCLUSIONS Early events during IPF onset in fibroblasts include dysregulation of ribosomal and copper-binding proteins. Fibroblasts in early stage IPF may have already acquired a profibrotic phenotype while hallmarks of advanced disease, including fibroblast foci and honeycomb formation, are still not evident. The new transitional fibroblasts we discover could prove very important for studying the role of fibroblast plasticity in disease progression and help develop early diagnosis tools and therapeutic interventions targeting earlier disease states.

Abstract
La tesis doctoral constituye un hito en la formación en investigación. Dadas las bajas tasas de egreso y los tiempos extensos de graduación en doctorados en Ciencias Sociales y Humanas, el objetivo de este estudio fue indagar la propuesta formativa del taller de tesis como dispositivo pedagógico para la formación en investigación en doctorados de la Ciudad Autónoma de Buenos Aires. Se realizó un estudio cualitativo, descriptivo y exploratorio cuyo análisis de datos finalizó en 2019. Se trabajó con una muestra de seis doctorados y dieciséis entrevistas. Las estrategias de recolección fueron un análisis documental y entrevistas semiestructuradas a directivos y docentes de talleres de tesis. Se indagaron objetivos, ubicación curricular, contenidos y estrategias de enseñanza de los talleres. Tres de los doctorados ofrecen un acompañamiento prolongado en el proceso de realización de la tesis, desde la definición del planteo del problema hasta la elaboración de apartados específicos, se ofrecen desde el inicio de la cursada y se mantienen a lo largo del doctorado; las estrategias didácticas y las propuestas de actividades se orientan a transmitir el oficio de investigar. Se concluye que cuando se dan algunas características de las comunidades de práctica y se ofrecen de manera prolongada es posible que los talleres de tesis en este campo puedan constituirse en dispositivos pedagógicos para la formación en investigación. Futuros trabajos pueden ahondar en estas conclusiones y ofrecer mayor detalle al integrar otras áreas al análisis, como la observación de los talleres o las tasas de egreso doctorales y su vínculo con los talleres u otros dispositivos.

Abstract
OBJECTIVE To study the relationship between sleep quality and memory in healthy ageing. METHODS The study included 99 people older than 50 years (69 women and 30 men; mean age, 68.74±7.18 years) with no associated diseases. Patients completed digital versions of the Word Learning and Visual Paired Associates tests and the Pittsburgh Sleep Quality Index questionnaire to assess the quality of sleep. RESULTS Pittsburgh Sleep Quality Index score was negatively correlated with Visual Paired Associates and Word Learning test performance. Performance in these 2 memory tests decreased in line with sleep quality. In addition, performance in Visual Paired Associates test was negatively correlated with subjective sleep quality, duration, and sleep disturbances. Performance on the Word Learning test was negatively correlated with subjective sleep quality and efficiency. Participants' sex showed a weak effect on Visual Paired Associates performance and sleep latency. CONCLUSIONS Medical professionals working with elderly patients should take into consideration the effect of poor sleep quality on memory. Cognitive impairment in these patients may be a manifestation of a neuroendocrine imbalance due to a disrupted circadian rhythm. More research is needed to prove this hypothesis.

Abstract
Fibroblast-to-myofibroblast transdifferentiation and the acquisition of a senescent phenotype are hallmarks of fibrotic diseases. The study of the localization of senescent myofibroblasts as well as their interactions with other cell types in the fibrotic tissue has been hindered by the lack of methods to detect these cells in vivo. Here, we describe methods to detect tissue localization of senescent myofibroblasts in precision-cut lung slices (PCLS) by combining β-galactosidase staining with immunofluorescence techniques.

Abstract
Background Chronic Obstructive Pulmonary Disease (COPD) is associated with an abnormal pulmonary and systemic immune response to tobacco smoking. Yet, how do immune cells relate within and between these two biological compartments, how the pulmonary infiltrate influences the lung transcriptome, and what is the role of active smoking vs. presence of disease is unclear. Methods To investigate these questions, we simultaneously collected lung tissue and blood from 65 individuals stratified by smoking habit and presence of the disease. The immune cell composition of both tissues was assessed by flow cytometry, whole lung transcriptome was determined with Affymetrix arrays, and we used Weighted Gene Co-expression Network Analysis (WGCNA) to integrate results. Results Main results showed that: (1) current smoking and the presence of COPD were both independently associated with a reduction in the proportion of lung T cells and an increase of macrophages, specifically those expressing CD80 + CD163+; (2) changes in the proportion of infiltrating macrophages, smoking status or the level of airflow limitation were associated to different WGCNA modules, which were enriched in iron ion transport, extracellular matrix and cilium organization gene ontologies; and, (3) circulating white blood cells counts were correlated with lung macrophages and T cells. Conclusions Mild-moderated COPD lung immune infiltrate is associated with the active smoking status and presence of disease; is associated with changes in whole lung tissue transcriptome and marginally reflected in blood.

Abstract
BACKGROUND c-Kit + lung stem cells have been described in the human healthy lung. Their potential relation with smoking and/or chronic obstructive pulmonary disease (COPD) is unknown. METHODS We characterized and compared c-Kit+ cells in lung tissue of 12 never smokers (NS), 15 smokers with normal spirometry (S) and 44 COPD patients who required lung resectional surgery. Flow cytometry (FACS) was used to characterize c-Kit+ cells in fresh lung tissue disaggregates, and immunofluorescence (IF) for further characterization and to determine their location in OCT- embedded lung tissue. RESULTS We identified 4 c-Kit+ cell populations, with similar proportions in NS, S and COPD: (1) By FACS, c-Kithigh/CD45+ cells (4.03 ± 2.97% (NS), 3.96 ± 5.30% (S), and 5.20 ± 3.44% (COPD)). By IF, these cells were tryptase+ (hence, mast cells) and located around the airways; (2) By IF, c-Kitlow/CD45+/triptase- (0.07 ± 0.06 (NS), 0.03 ± 0.02 (S), and 0.06 ± 0.07 (COPD) cells/field), which likely correspond to innate lymphoid cells; (3) By FACS, c-Kitlow/CD45-/CD34+ (0.95 ± 0.84% (NS), 1.14 ± 0.94% (S) and 0.95 ± 1.38% (COPD)). By IF these cells were c-Kitlow/CD45-/CD31+, suggesting an endothelial lineage, and were predominantly located in the alveolar wall; and, (4) by FACS, an infrequent c-Kitlow/CD45-/CD34- population (0.09 ± 0.14% (NS), 0.08 ± 0.09% (S) and 0.08 ± 0.11% (COPD)) compatible with a putative lung stem cell population. Yet, IF failed to detect them and we could not isolate or grow them, thus questioning the existence of c-Kit+ lung stem-cells. CONCLUSIONS The adult human lung contains a mixture of c-Kit+ cells, unlikely to be lung stem cells, which are independent of smoking status and/or presence of COPD.

Abstract
RATIONALE Chronic obstructive pulmonary disease (COPD) is characterized by chronic airflow limitation caused by a combination of airways disease (bronchiolitis) and parenchymal destruction (emphysema), whose relative proportion varies from patient to patient. OBJECTIVES To explore and contrast the molecular pathogenesis of emphysema and bronchiolitis in COPD. METHODS We used network analysis of lung transcriptomics (Affymetrix arrays) in 70 former smokers with COPD to compare differential expression and gene coexpression in bronchiolitis and emphysema. MEASUREMENTS AND MAIN RESULTS We observed that in emphysema (but not in bronchiolitis) (1) up-regulated genes were enriched in ontologies related to B-cell homing and activation; (2) the immune coexpression network had a central core of B cell-related genes; (3) B-cell recruitment and immunoglobulin transcription genes (CXCL13, CCL19, and POU2AF1) correlated with emphysema severity; (4) there were lymphoid follicles (CD20(+)IgM(+)) with active B cells (phosphorylated nuclear factor-κB p65(+)), proliferation markers (Ki-67(+)), and class-switched B cells (IgG(+)); and (5) both TNFRSF17 mRNA and B cell-activating factor protein were up-regulated. These findings were by and large reproduced in a group of patients with incipient emphysema and when patients with emphysema were matched for the severity of airflow limitation of those with bronchiolitis. CONCLUSIONS Our study identifies enrichment in B cell-related genes in patients with COPD with emphysema that is absent in bronchiolitis. These observations contribute to a better understanding of COPD pathobiology and may open new therapeutic opportunities for patients with COPD.

Abstract
Chronic obstructive pulmonary disease (COPD) is characterised by pulmonary and systemic inflammation that bursts during exacerbations of the disease (ECOPD). The NLRP3 inflammasome is a key regulatory molecule of the inflammatory response. Its role in COPD is unclear. We investigated the NLRP3 inflammasome status in: 1) lung tissue samples from 38 patients with stable COPD, 15 smokers with normal spirometry and 14 never-smokers; and 2) sputum and plasma samples from 56 ECOPD patients, of whom 41 could be reassessed at clinical recovery. We observed that: 1) in lung tissue samples of stable COPD patients, NLRP3 and interleukin (IL)-1β mRNA were upregulated, but both caspase-1 and ASC were mostly in inactive form, and 2) during infectious ECOPD, caspase-1, oligomeric ASC and associated cytokines (IL-1β, IL-18) were significantly increased in sputum compared with clinical recovery. The NLRP3 inflammasome is primed, but not activated, in the lungs of clinically stable COPD patients. Inflammasome activation occurs during infectious ECOPD. The results of this study suggest that the inflammasome participates in the inflammatory burst of infectious ECOPD. The NLRP3 inflammasome is primed in stable COPD lungs, then activated during infectious exacerbationhttp://ow.ly/Wopi300DXcT

Abstract
Noncommunicable diseases, including cardiovascular, metabolic and respiratory diseases, among others, are the major medical challenge of the 21st century. Most noncommunicable diseases are related to the ageing process and often co-occur in the same individual. However, it is unclear whether the index disease is somehow influencing the development of the other ones (comorbidity) or whether all of them (including the index disease) simply represent the clinical expression of pathological ageing (multimorbidity). The pathobiology of ageing, chronic obstructive pulmonary disease (COPD) and concomitant disorders is complex. A new field of research, known as systems biology if applied to model systems or network medicine if applied to human beings, has emerged over the past decade or so, to address biological complexity in a holistic, integrated way. It offers, therefore, great potential to decipher the relationship between ageing, COPD and comorbidities/multimorbidities. In this State of the Art review we present the basic concepts of systems biology, use some examples to illustrate the potential of network medicine to address complex medical problems, and review some recent publications that show how a systems-based research strategy can contribute to improve our understanding of multimorbidity and age-related respiratory diseases.

Abstract
Chronic obstructive pulmonary disease (COPD) is a major public health problem because of its high prevalence, rising incidence and associated socio-economic cost. The inhalation of toxic particles and gases, mostly tobacco smoke, is the main risk factor for COPD. Yet, not all smokers are equally susceptible to these toxic effects and only a percentage of them develop the disease (so-called 'susceptible smokers'). This, in combination with the observation that COPD shows familial aggregation, suggests that the genetic background of the smoker is a key element in the pathogenesis of the disease. On the other hand, it is well established that 'susceptible' smokers exhibit an enhanced inflammatory response of the lung parenchyma as compared with 'resistant' smokers (i.e., those who manage to maintain lung function within the normal age range despite their habit). Importantly, in COPD patients this inflammatory response does not resolve after quitting smoking, again at variance with resistant smokers. All in all, these observations suggest that the pathogenesis of COPD may involve, in some patients, an autoimmune component which contributes to the enhanced and persistent inflammatory response that characterizes the disease. Here we: i) review briefly the pathobiology of COPD; ii) present the available scientific evidence supporting a potential role for autoimmunity in COPD; iii) propose a three-step pathogenic hypothesis in the transition from smoking to COPD; and iv) discuss potential implications for the diagnosis and treatment of this frequent, growing, devastating and costly disease.

Abstract
BACKGROUND Tobacco smoking is the main risk factor of chronic obstructive pulmonary disease (COPD) but not all smokers develop the disease. An abnormal pulmonary and systemic inflammatory response to smoking is thought to play a major pathogenic role in COPD, but this has never been tested directly. METHODS We studied the systemic biomarker and leukocyte transcriptomic response (Affymetrix microarrays) to smoking exposure in 10 smokers with COPD and 10 smokers with normal spirometry. We also studied 10 healthy never smokers (not exposed to smoking) as controls. Because some aspects of COPD may differ in males and females, and the inflammatory response to other stressors (infection) might be different in man and women, we stratified participant recruitment by sex. Differentially expressed genes were validated by q-PCR. Ontology enrichment was evaluated and interaction networks inferred. RESULTS Principal component analysis identified sex differences in the leukocyte transcriptomic response to acute smoking. In both genders, we identified genes that were differentially expressed in response to smoking exclusively in COPD patients (COPD related signature) or smokers with normal spirometry (Smoking related signature), their ontologies and interaction networks. CONCLUSIONS The use of an experimental intervention (smoking exposure) to investigate the transcriptomic response of peripheral leukocytes in COPD is a step beyond the standard case-control transcriptomic profiling carried out so far, and has facilitated the identification of novel COPD and Smoking expression related signatures which differ in males and females.

Abstract
Aspergillosis, the most frequent of pulmonary mycosis, represents a group of varying pathogenesis diseases with the same etiological agent--Aspergillus. This fungus is a saprophyte of normal respiratory airways, but the disease occurs in immunocompromised hosts. There are several anatomo-clinical forms, but it is important to know that some could be fatal, being necessary an early diagnosis and therapy. The authors describe an Invasive Pulmonary Aspegillosis case, in a immunocompromised patient submitted to long term corticotherapy treatment. Was started with liposomal Amphotericin B, discontinued due to nephrotoxicity and substituted by Itraconazol, with clinical, laboratorial and radiologic favourable evolution, as it's proven by imagiological studies.

Abstract
The therapeutic value of Florfenicol feed supplemented was evaluated in conventional pigs to eliminate consequences of chronic infection of Mycoplasma hyopneumoniae. The experimental animals were pigs with an average of 16 kg, after intratracheally inoculation with M. hyopneumoniae they were divided in two experimental groups: (a) the non-medicated; and (b) the feed supplemented group (20 g Florfenicol/ton of feed) during the ensuing 35 days. The average daily weight gain of the Florfenicol-treated pigs (0.33±0.14 kg/day) was significantly higher than that of the non-treated ones (0.21±0.10 kg/day). In medicated animals was still impaired relative to that of the uninfected ones control group (0.39±0.02 kg/day). The average percentage of pneumonic gross lesions extensions' of the pigs groups was: 13.99% for M. hyopneumoniae infected non-medicated group; 1.79% M. hyopneumoniae infected, Florfenicol-treated group and, 0.56% of the uninfected control group. M. hyopneumoniae; colonization was detected at these levels in 7 and 9 members of the respective infected groups. The extent of the pneumonic lesions and M. hyopneumoniae generally was greater in the non-medicated pigs. Therefore, oral administration of Florfenicol via feed ingestion seemed to be somewhat effective in ameliorating the clinical effects of M. hyopneumoniae infection of swine.

Abstract
BACKGROUND In Brazil hospital malnutrition is highly prevalent, physician awareness of malnutrition is low, and nutrition therapy is underprescribed. One alternative to approach this problem is to educate health care providers in clinical nutrition. The present study aims to evaluate the effect of an intensive education course given to health care professionals and students on the diagnosis ability concerning to hospital malnutrition. MATERIALS AND METHODS An intervention study, based on a clinical nutrition educational program, offered to medical and nursing students and professionals, was held in a hospital of the Amazon region. Participants were evaluated through improvement of diagnostic ability, according to agreement of malnutrition diagnosis using Subjective Global Assessment before and after the workshop, as compared to independent evaluations (Kappa Index, k). To evaluate the impact of the educational intervention on the hospital malnutrition diagnosis, medical records were reviewed for documentation of parameters associated with nutritional status of in-patients. The SPSS statistical software package was used for data analysis. RESULTS A total of 165 participants concluded the program. The majority (76.4%) were medical and nursing students. Malnutrition diagnosis improved after the course (before k = 0.5; after k = 0.64; p < 0.05). A reduction of false negatives from 50% to 33.3% was observed. During the course, concern of nutritional diagnosis was increased (chi2 = 17.57; p < 0.001) and even after the course, improvement on the height measurement was detected (chi2 = 12.87; p < 0.001). CONCLUSIONS Clinical nutrition education improved the ability of diagnosing malnutrition; however the primary impact was on medical and nursing students. To sustain diagnostic capacity a clinical nutrition program should be part of health professional curricula and be coupled with continuing education for health care providers.

Abstract
UNLABELLED Data concerning the effects of GnRHa on weight gain are scarce. OBJECTIVE To assess the variation of the body mass index (BMI) in girls during GnRHa treatment for idiopathic central precocious puberty (CPP). PATIENTS AND METHODS Semestral anthropometric data from 176 girls treated with goserelin or leuprorelin were analyzed. RESULTS BMI z-score increased from 1.5 +/- 0.1 SD before treatment (n = 176) to 1.7 +/- 0.2 SD after 24 months (n = 61, p = 0.008). In girls with normal weight before treatment, this variation was greater (n = 112, 0.2 +/- 0.1 SD, p = 0.01) than in those who were overweight (n = 63, -0.9 +/- 0.2 SD, p = 0.7). In the goserelin group the weight change adjusted for bone age was greater (n = 28, 0.4 +/- 0.1 SD) than in the leuprorelin group (n = 5, 0.04 +/- 0.1 SD, p = 0.05). CONCLUSIONS A slight increase in BMI was noted, mainly in girls with normal weight before treatment. The influence of different GnRHa on weight must be further investigated.

Abstract
INTRODUCTION The quality of life (QOL) of patients with morbid obesity (MO) is reduced given the restrictions it imposes. Bariatric surgery is considered an efficient treatment for MO as it leads to marked and progressive weight reduction. Weight loss, appropriate nutritional advice and follow up may induce significant improvement in QOL. AIM To evaluate the degree of QOL in patients with MO before and after bariatric, surgery (Fobi-Capella reducing gastroplasty). CASES. MATERIAL AND METHODS 95 morbidly obese(BMI > 40 kg/m2) or moderately obese (BNI 35 - 39 kg/m2) patients with co-morbidities were seen, followed up and given advice by the Nutrition, Psychology, Endocrinology and Surgery staff at the Federal University of Bahia Hospital. Group I included 66 subjects at the pre-surgical stage and Group II was composed of 29 other patients in a late postsurgical phase. Group II patients were seen at 6, 12 and more months after bariatric surgery. The medical outcomes study Short-Form Health Survey (SF-36) was the instrument used to evaluate QOL in this study. Data were analyzed using the Mann-Whitney non-parametric method and the SPSS program. RESULTS A statistically significant improvement in QOL was detected in the aspects of general health, functional ability and vitality. A progressive improvement in physical conditioning was particularly observed in the patients who had had bariatric surgery less than 6 months before, between 6 and 12 months and more than 12 months before. Small changes in subjective features were seen. An improvement in social aspects was observed after a post surgical fall. This explains why do not changes appear when pre and post surgical patients are compared. CONCLUSIONS Fobi-Capella bariatric surgery for our patients with MO or with co-morbidities associated moderate obesity resulted in QOL improvement, and gradual but marked improvements in physical condition over time.

Abstract
OBJECTIVES To assess the biocompatibility of controlled release microspheres prepared from different polymeric biomaterials in various size ranges in rabbit synovial joints and based on these data, design and evaluate the efficacy of an intra-articular, paclitaxel-loaded microspheres formulation in rabbit models of arthritis. METHODS Paclitaxel-loaded microspheres of poly(lactide-co-glycolide) (PLGA), poly(L-lactic acid) (PLA) and poly(caprolactone) (PCL) were prepared in different size ranges and inflammatory responses monitored following injection into healthy rabbit joints. The efficacy of 20% paclitaxel-loaded PLA microspheres (35-105 microm size range) injected intra-articularly into antigen and carrageenan induced rabbit models of arthritis was monitored. RESULTS Polymeric microspheres in the 35-105 microm size range were biocompatible whereas smaller microspheres (1-20 microm) produced an inflammatory response. Efficacy studies showed that injection of 20% paclitaxel-loaded PLA microspheres significantly reduced all measures of inflammation in the antigen arthritis rabbit model. CONCLUSIONS Paclitaxel-loaded PLA microspheres in the 35-105 microm size range, released paclitaxel in a controlled manner over several weeks, and may be a potential formulation for the intra-articular treatment of inflammation in arthritic conditions.

Abstract
OBJECTIVE To show the results of Radioimmunodetection (RID) using Cuban monoclonal antibody (MoA) anti-egf-ior-egf-r3 labeled with 99mTc for the detection of primary tumors and/or metastases of head and neck epithelial malignant tumors. MATERIAL AND METHODS Thirteen patients aged from 16-62 years (mean: 54.8 years) with primary tumors and metastases in the regional cervical lymph nodes were retrospectively evaluated. The labelling dose was 1480-2220 MBq (40-60 mCi). Planar images were performed after 10 minutes and together with SPECT images after 18-24 hours following MoA administration. The matrix was 128 x 128. SPECT images were reconstructed using the Butterworth 4/16 filter. A positive result was defined when the lesions were visualized. RESULTS RID localized 11 of the known primary tumors in the 13 patients studied. In the two other patients, in whom the primary tumor site was unknown, cervical lymph node metastases were found. The results of 3 of the RID were false negative but in the other 10, RID was able to localize the primary tumor and cervical lymph node metastases. Sensitivity was 77 % and the predictive positive value was 100 %. CONCLUSIONS The results of this study show that the Cuban MoA ior-egf-r3 can be employed for RID of primary head and neck tumors and their metastases. The radiation dose is adequate for RID.

Abstract
UNLABELLED Changes in nutritional status are important in clinical practice because they relate to an increase in morbidity and mortality. Studies about nutritional problems in hospitalized adults have been reported since the 1970s. The prevalence of malnutrition has varied from 10 to 70%, depending on the diagnostic criteria used. The hospital studied and the duration of admission. AIM To assess, in the first day of hospital stay, the nutritional status of adults admitted to undergo elective surgery in a public hospital of the State of Acre, Amazon Region, Brazil. STUDY DESIGN Sectional study from April 7 to May 22, 2002. PATIENTS AND METHODS 155 consecutive nutritional evaluations were performed using several parameters-global subjective assessment (GSA), anthropometric measurement and some laboratory tests. For the diagnosis of malnutrition the Index Suggestive of Malnutrition (ISM), as proposed by Waitzberg, was adopted. In the evaluation of obesity the BMI (Body Mass Index), with cutoffs suggested by WHO was used. RESULTS 75.2% were women. Average age was 34.4 +/- 10.1 years. Mulatto (63.1%) was the prevailing racial group. Gynecological (43.6%) was the most frequent surgery. ISM disclosed a 12.1% prevalence of malnutrition. BMI classified 2.0% of the patients as grade I overweight and 15.4% as being obese. Among 76 patients classified as normal by BMI, 15 (19.7%) were considered malnourished by ISM criteria. Concordance between ISM and BMI was weak (k = 0.07). GSA classified 100% of the cases as well nourished. CONCLUSION Lack of a golden standard to make the diagnosis of changes in nutritional status has been one of the determinants of the wide variations observed in the pertinent literature and it has hindered valid comparisons. The present study suggests that BMI should be used as an indicator of proportion and not of nutritional status. GSA underestimates the diagnosis of malnutrition. This paper concludes that establishing uniform standards for diagnostic criteria for malnutrition is urgently required and suggests preferring IMS (Index Suggestive of Malnutrition) because of its easy use, low coast and high sensitivity.

Abstract
Aspergillosis, the most frequent of pulmonary mycosis, represents a group of varying pathogenesis diseases with the same etiological agent--Aspergillus. This fungus is a saprophyte of normal respiratory airways, but the disease occurs in immunocompromised hosts. There are several anatomo-clinical forms, but it is important to know that some could be fatal, being necessary an early diagnosis and therapy. The authors describe an Invasive Pulmonary Aspegillosis case, in a immunocompromised patient submitted to long term corticotherapy treatment. Was started with liposomal Amphotericin B, discontinued due to nephrotoxicity and substituted by Itraconazol, with clinical, laboratorial and radiologic favourable evolution, as it's proven by imagiological studies.

Abstract
Infection with human herpesvirus type 8 and with human T-cell leukaemia virus type-1 shows strong geographic variations. We conducted this study to assess prevalence and risk factors for human herpesvirus type 8 infection in Havana City, Cuba. Information and residual serum samples already collected for a hospital based case-control study were used. A total of 379 individuals (267 males and 112 females; median age=63 years) were evaluated. Antibodies to the lytic antigen of human herpesvirus type 8 were detected by using an immunofluorescence assay, while human T-cell leukaemia virus type-1 serology was performed by means of an ELISA test (alpha Biotech). Overall, 64 subjects (16.9%, 95% confidence interval: 13.1-20.0) were positive for human herpesvirus type 8 antibodies. Human herpesvirus type 8 seroprevalence significantly increased with age (odds ratio=1.9 for >/=65 vs <55 years), and was twice as frequent in blacks than in whites. No association emerged with gender, socio-economic indicators, family size, history of sexually transmitted disease, sexual behaviour. Overall, 16 persons had anti-human T-cell leukaemia virus type-1 antibodies (4.2%, 95% confidence interval: 2.2-6.4). No relationship emerged between human T-cell leukaemia virus type-1 and human herpesvirus type 8 serostatus. The study findings indicate that human herpesvirus type 8 infection is relatively common in Havana City, Cuba, suggesting that Cuba may represent an intermediate endemical area. Sexual transmission does not seem to play a major role in the spread human herpesvirus type 8 infection.

Abstract
BACKGROUND Morin, a bioflavonoid with antioxidant properties, shows intestinal anti-inflammatory activity in the acute phase of the trinitrobenzenesulphonic acid model of rat colitis. AIM To assess the anti-inflammatory activity of morin in the chronic stages of trinitrobenzenesulphonic acid-induced rat colitis. METHODS Rats were rendered colitic by a single colonic instillation of 30 mg of the hapten trinitrobenzenesulphonic acid dissolved in 0.25 mL of 50% ethanol. A group of colitic animals was given morin orally at doses of 25 mg/kg daily. Animals were sacrificed every week for 4 weeks. Colonic damage was evaluated macroscopically and microscopically. Different biochemical markers of colonic inflammation were also assayed, including myeloperoxidase activity, leukotriene B4 and interleukin-1beta synthesis, glutathione and malonyldialdehyde levels and nitric oxide synthase activity. RESULTS The administration of morin facilitated tissue recovery during the 4 weeks following colonic insult with trinitrobenzenesulphonic acid, as demonstrated macroscopically and microscopically, as well as biochemically by a reduction in myeloperoxidase activity. The intestinal anti-inflammatory effect of morin was accompanied by a significant reduction in colonic leukotriene B4 and interleukin-1beta levels, improvement in colonic oxidative stress and inhibition of colonic nitric oxide synthase activity. CONCLUSIONS Morin exerts a beneficial anti-inflammatory effect in the chronic phase of trinitrobenzenesulphonic acid-induced rat colitis through the down-regulation of some of the mediators involved in the intestinal inflammatory response, including free radicals, cytokines, leukotriene B4 and nitric oxide.

Abstract
Gangrenous cystitis is a rare condition, there are no typical symptoms or clinical findings, which hampers diagnosis and may worsen the prognosis. The authors report the case of a diabetic male patient, hospitalized because of poor general condition, dehydration and diffuse abdominal pain. The diagnosis was made by typical pelvic CT findings. Medical treatment must be intensive and begun as soon as possible. As in the present case, the situation may have a favorable outcome.

Abstract
The intestinal anti-inflammatory activity of several doses of silymarin was tested in the acute stage of the trinitrobenzenesulfonic acid (TNBS) model of rat colitis. The results obtained show that oral pre-treatment with 50 mg/kg of silymarin significantly attenuated macroscopic colonic damage as well as reduced colonic myeloperoxidase activity compared to non-treated colitic animals. The beneficial effect was accompanied by an improvement in the colonic oxidative status, which was altered in colonic inflammation, by preventing glutathione depletion and reducing malonyldialdehyde production. This suggests that the well known antioxidant properties of silymarin can participate in its intestinal anti-inflammatory activity. In addition, a preservation in the colonic absorptive function was also observed, and this effect can also account for the colonic protective effect observed in this model of acute colitis.

Abstract
High prevalence of thyroid autoantibodies, with or without overt thyroiditis, has been described in hepatitis C patients, particularly in those undergoing alpha-interferon treatment. The aim of this study was to describe the frequency and clinical outcome of thyroid disease in a cohort of HCV carriers before and during combination therapy with interferon plus ribavirin. Between May, 1997, and May, 1999, 111 previously untreated (naive) patients were treated with a-interferon plus ribavirin for 6 or 12 months. Of those, 67 (60%) patients were male and 44 (40%) female. Thyroid function was evaluated in all patients by testing free T4, TSH and antiTPO within 30 days prior to treatment, 90 days after treatment was initiated, and 6 months after treatment was concluded. Abnormal thyroid tests were observed in 4 (3.6%) patients--1 male and 3 female--before the onset of antiviral treatment. Three patients were already undergoing T4 replacement due to Hashimoto thyroiditis and 1 patient had positive antiTPO with normal free T4 and TSH. All 4 patients completed the treatment regime for HCV, but required hormone replacement. Among the patients with a normal thyroid function test prior to treatment (107 cases), 5 (4.6%) developed thyroid test abnormalities; 2 patients had hypothyroidism due to autoimmune thyroiditis; 1 patient became positive for antiTPO antibodies but thyroid function remained normal, and 2 patients had subacute thyroiditis. Four of these patients (80%) were female and 1 was male (20%). A family history of thyroid disease was strongly predictive of thyroid abnormalities during antiviral treatment. In conclusion, there is a low prevalence of thyroid function abnormalities in HCV carriers with no prior antiviral treatment. Family history of thyroid disease reinforces the special attention to thyroid abnormality development before considering antiviral therapy. Subacute thyroiditis during combination therapy was observed, but its pathogenesis is still unknown. Evaluation of thyroid function during and after antiviral treatment is strongly recommended because thyroid related symptoms can be easily misinterpreted as medication side effects.

Abstract
Autoimmune thyroiditis has been frequently reported during interferon monotherapy for hepatitis C, but there are few reports concerning subacute thyroiditis. Recently, combination therapy of IFN plus ribavirin has become the preferred therapeutic schedule for chronic hepatitis C. Similarly to interferon monotherapy, there are no reports concerning subacute thyroiditis during combination therapy. We described four episodes of subacute thyroiditis occurring in three patients during antiviral combination therapy. All patients had symptoms compatible with hyperthyroidism, which could be misdiagnosed as IFN side-effects. The antiviral treatment was continued in all three patients and thyroid function increased progressively with pharmacological treatment for hyperthyroidism. We concluded that subacute thyroiditis may be a complication of combination antiviral therapy and should be investigated in patients presenting with compatible symptoms, in order to differentiate from IFN side-effects.
