RESUMO

Outdoor physical activity has become one of the main trends in Europe, specially the practice in informal places such as parks, streets or natural surrounds. The purpose of this study is to go in depth the knowledge of sports practice in urban green areas, their meanings and motivations in the environment of a medium-sized Spanish city.Considering the object of study nature, a case study design in the city of Zaragoza was chosen. This work shows a qualitative research, where three focus group with 28 participants were carried out.Results point to sports practice increase in urban green areas could be due to city expansion, green areas promotion, economic situation, sport and health links, sports culture evolution, and trends and fashions.

La actividad física al aire libre se ha convertido en una de las principales tendencias en Europa, especialmente la practicada en espacios informales tales como parques, calles o entornos naturales. Este estudio tiene como finalidad profundizar en el conocimiento de la práctica físico-deportiva en áreas verdes urbanas, sus significados y motivaciones, en el entorno de una ciudad española de tamaño medio. Dada la naturaleza del objeto de estudio, se optó por un diseño de estudio de caso en la ciudad de Zaragoza. En este trabajo se presenta una investigación de tipo cualitativo donde se realizaron tres focus group con 28 participantes. Los resultados indican que el aumento de la práctica físico-deportiva en espacios verdes urbanos podría deberse a la expansión de la ciudad, la promoción de zonas verdes, la situación económica, los vínculos entre deporte y salud, la evolución de la cultura deportiva, y las tendencias y modas.

RESUMO

BACKGROUND: Chronic obstructive pulmonary disease (COPD) has been proposed as a disease of accelerated aging. Several cross-sectional studies have related a shorter telomere length (TL), a marker of biological aging, with COPD outcomes. Whether accelerated telomere shortening over time relates to worse outcomes in COPD patients, is not known. METHODS: Relative telomere length (T/S) was determined by qPCR in DNA samples from peripheral blood in 263 patients at baseline and up to 10 years post enrolment. Yearly clinical and lung function data of 134 patients with at least two-time measures of T/S over this time were included in the analysis. RESULTS: At baseline, T/S inversely correlated with age (r = - 0.236; p < 0.001), but there was no relationship between T/S and clinical and lung function variables (p > 0.05). Over 10 years of observation, there was a median shortening of TL of 183 bp/year for COPD patients. After adjusting for age, gender, active smoking and mean T/S, patients that shortened their telomeres the most over time, had worse gas exchange, more lung hyperinflation and extrapulmonary affection during the follow-up, (PaO2 p < 0.0001; KCO p = 0.042; IC/TLC p < 0.0001; 6MWD p = 0.004 and BODE index p = 0.009). Patients in the lowest tertile of T/S through the follow-up period had an increased risk of death [HR = 5.48, (1.23-24.42) p = 0.026]. CONCLUSIONS: This prospective study shows an association between accelerated telomere shortening and progressive worsening of pulmonary gas exchange, lung hyperinflation and extrapulmonary affection in COPD patients. Moreover, persistently shorter telomeres over this observation time increase the risk for all-cause mortality.

RESUMO

PURPOSE: To evaluate the dose effect of vitamin K3 on wound healing mechanisms. METHODS: Conjunctival fibroblasts were incubated for 24 hours. An artificial wound was made and the cells were incubated with fresh medium plus doses of vitamin K3 to be tested. Wound repair was monitored at 0, 18, 24, and 48 hours. Proliferation was measured in actively dividing cells by [(3)H]thymidine uptake. Six different groups were tested: group 1/no drugs added, group 2/ethanol 0.1%, group 3/vitamin K3 1 mg/L, group 4/vitamin K3 2 mg/L, group 5/vitamin K3 4 mg/L, and group 6/vitamin K3 6 mg/L. Each experiment was carried out in triplicate and 4 times. RESULTS: There were no differences among groups at the initial time. In vitro wound repair was slower in groups 4, 5, and 6. There were no differences between control and ethanol groups and between control and vitamin K3 1 mg/L groups. Fibroblast mitogenic activity was statistically decreased in all vitamin K groups; statistical differences were found among vitamin K3 1 mg/mL and higher doses too. In groups 5 and 6, cellular toxicity was presented. CONCLUSIONS: Vitamin K3 is able to inhibit fibroblast proliferation. Vitamin K3 2 mg/L or higher doses inhibit wound healing repair, exhibiting cellular toxicity at 4 and 6 mg/L.

RESUMO

PURPOSE: To determine the glaucomatous visual field damage patterns by short-wavelength automated perimetry (SWAP) in glaucoma suspects, and to compare the frequency of diffuse visual field losses and localized defects. METHODS: 157 eyes of 157 ocular hypertensive subjects who met the selection criteria (intraocular pressure greater than 21 mm Hg and normal standard visual fields) were studied. SWAP was done with a modified Humphrey Field Analyzer. Total (TD) and Pattern Deviation (PD) probability maps were calculated for SWAP. The frequency of abnormlities in the TD and PD were determined, analyzing the visual field loss components. RESULTS: The involvement of the test points was more frequent on the TD plots than on the PD plots for all levels of defects (p< 0.001). The glaucomatous defects also showed certain topographical distribution. CONCLUSIONS: A diffuse sensitivity component of visual field loss was found at all SWAP defect depths in glaucoma suspects.

RESUMO

PURPOSE: To evaluate efficacy and reliability of local intra-arterial fibrinolysis (LIF) in Retinal Central Artery Occlusion (RCAO). MATERIAL AND METHOD: We have studied 12 patients with RCAO. Seven patients (group I) were treated with conventional therapy and 5 patients (group II) underwent treatment with urokinase via transcutaneous femoral catheter into the ophthalmic artery. Thereafter patients received heparin sulfate for 3 days. RESULTS: Mean follow up was 14 months and mean time from onset of symptoms to the beginning of therapy was 11 hours. One patient in group I showed improvement of visual acuity (from counting fingers to 0.1). In all patients in group II there was angiographic evidence of improved perfusion of retinal arteries and 4 patients (80%) showed improvement in visual acuity. The best results were obtained when LIF was performed before 10 hours after onset of symptoms. No complications were observed after the fibrinolysis treatment. CONCLUSION: LIF in ophtalmic arteries for the treatment of RCAO reduces dosage of fibrinolytic agents and becomes a safe and useful treatment during the first hours post RCAO.

RESUMO

PURPOSE: To determine width and shape of neuro-retinal rim in normal hypertensive subjects and patients with glaucomatous damage. MATERIAL AND METHOD: Patients underwent a perimetry and a photographic retinal nerve fiber evaluation. Patients were divided in three groups: normal subjects (n=34), ocular hypertension subjects (n=38) and glaucoma patients (n=34). Neuro-retinal rim was measured using 40 degrees stereoscopic photographs with center in the optic nerve head based on a biomorphometry technique. RESULTS: In normal subjects neuro-retinal rim appeared wider in the lower pole, followed by the upper, nasal and temporal aspects. Optic nerve fiber layer showed a decreased thickness in hypertensive and glaucoma patients, particularly in sectors of the temporal aspect of the optic nerve (p<0.05). CONCLUSIONS: A Planimetry study of the optic nerve is able to detect alterations in normal neuro-retinal rim configuration and can as well detect thinning of the rim, particularly in temporal, upper and lower areas.

RESUMO

Objetivo: Determinar los espesores del anillo neurorretiniano y su configuración a lo largo del borde papilar en sujetos normales, hipertensos y con daño glaucomatoso. Material y Método: Tras exploración perimétrica y estudio fotográfico de la capa de fibras nerviosas de la retina, los sujetos se distribuyeron en 3 grupos: normales (n=34), hipertensos oculares (n=38) y glaucomatosos (n=34). A partir de fotografías estereoscópicas de 40° centradas en el nervio óptico se determinó el grosor del anillo neurorretiniano en cada radio papilar mediante planimetría papilar. Resultados: En los sujetos normales, el grosor del anillo neurorretiniano fue mayor en el polo inferior, seguido del superior, zona nasal y temporal. Existió una disminución del grosor de la capa de fibras del nervio óptico en pacientes hipertensos y glaucomatosos, más acentuada en las regiones temporales de la papila (p<0,05).Conclusiones: El estudio papilar mediante planimetría puede detectar alteraciones en la configuración normal del anillo neurorretiniano y la presencia de adelgazamientos, que suelen ser más pronunciados en las regiones temporales del anillo neurorretiniano (AU)

RESUMO

PURPOSE: To assess the differences in neuroretinal rim shape in ocular hypertensive patients (normal white-white automated perimetry) with and without perimetric injury in the short wave length automated perimetry (blue-yellow). MATERIAL AND METHODS: 72 eyes from 72 hypertensive ocular patients with normal achromatic automated perimetry examination were included. Forty eyes had normal short wave length automated perimetries while 32 subjects presented an abnormal condition. The neuroretinal rim morphology was quantified by means of a planimetric study from the papillary images obtained with confocal laser scanning. RESULTS: The subjects with abnormal blue-yellow perimetry showed a decrease in the neuroretinal rim area in the inferior and temporal positions. The differences were significant (p<0.05) at the 9 o'clock position (below the middle line) and almost significant (p<0.10) at the 10 o'clock position. CONCLUSIONS: There are differences in the neuroretinal rim shape in ocular hypertensive subjects with normal achromatic perimetry according to whether there are abnormalities in the blue-yellow perimetry.

RESUMO

Objetivo: Determinar las diferencias en la morfología del anillo neurorretiniano que presentan sujetos hipertensos oculares (sin alteración perimétrica blanco-blanco) con y sin daño perimétrico en la perimetría automatizada de longitud de onda corta (azul-amarillo). Material y método: Se incluyeron 72 ojos de 72 hipertensos oculares con exploración perimétrica acromática normal, de los que 40 presentaron una perimetría automatizada de longitud de onda corta normal y 32, patológica. Se cuantificó la morfología del anillo neurorretiniano mediante estudio planimétrico a partir de imágenes papilares obtenidas mediante láser confocal de barrido. Resultados: Los sujetos con perimetría azul-amarillo patológica presentaron menor anillo neurorretiniano en las posiciones horarias inferiores y temporales, siendo las diferencias significativas (p<0,05) en la posición '9 horas' (por debajo de la línea media). Conclusiones: En sujetos hipertensos oculares con perimetría computarizada acromática normal existen diferencias en la configuración del anillo neurorretiniano en dependencia de la presencia o no de daño perimétrico en la perimetría azul-amarillo (AU)

RESUMO

PURPOSE: To present a rare case of central retinal vein occlusion in conjunction with the HELLP syndrome. METHODS: A 30-year-old woman presented in the 28th week of her second pregnancy with severe pre-eclampsia with HELLP syndrome; delivery by caesarean section was recommended. Ten days later, the patient complained of severely decreased visual acuity in her right eye. RESULTS: Ophthalmoscopy revealed a central retinal vein occlusion with venous engorgement and tortuosity, multiple flame hemorrhages, and disc and macular edema. Electroretinography revealed a reduction of b-wave/a-wave ratio. Fluorescein-angiography showed a blockage due to extensive retinal hemorrhages with late mild staining of the walls of veins. The patient presented a spontaneous improvement in visual acuity (0.8 two months after) and a complete resolution of ophthalmoscopic findings. CONCLUSION: Ophthalmic complications are possible during and soon after this syndrome. This is the first description of a patient suffering a central retinal vein occlusion during puerperium after the HELLP syndrome.

RESUMO

Objetivo: Estudiar en conejos albinos la capacidad antiinflamatoria del pranoprofeno tópico comparada con otros antiinflamatorios no esteroideos (AINEs) de uso en oftalmología (diclofenaco y flurbiprofeno).Métodos: Se indujo una uveítis mediante inyección intravítrea de 10 ng/5 µL de endotoxina de Salmonella typhimurium en el ojo derecho del animal de experimentación. Se utilizaron 48 conejos albinos divididos en 4 grupos de 12, siendo el grupo I el control (inyección intravítrea de suero fisiológico), se aplicaron los siguientes tratamientos (en ojo derecho) cada 2 horas: Grupo II, 2 gotas de pranoprofeno (1 mg/ml). Grupo III, 2 gotas de diclofenaco (0,2 mg/ml). Grupo IV, 2 gotas de flurbiprofeno (0,3 mg/ml). A las 24 horas de la administración de la endotoxina se sacrificaron los conejos tras la determinación de la valoración clínica y la concentración de proteínas en humor acuoso. Resultados: Se observó una reducción significativa respecto al control de los parámetros estudiados (hiperemia del iris, tyndall, exudado pupilar y concentración de proteínas) excepto la hiperemia ciliar, en todos los grupos de tratamiento. Los distintos grupos tratados no mostraron diferencias entre sí. Conclusiones: La capacidad antiinflamatoria del pranoprofeno es comparable a la de otros AINEs derivados del ácido propiónico como el flurbiprofeno, consiguiendo una reducción significativa de la inflamación en la uveítis inducida por endotoxina (AU)

RESUMO

PURPOSE: To study the antiinflammatory capacity of topical pranoprofen in comparison with other ophthalmological nonsteroidal antiinflammatory drugs (diclofenac and flurbiprofen) in albino rabbits. METHODS: We have produced an endotoxin-induced uveitis by intravitreal injection of 10 ng of Salmonella typhimurium endotoxin. We have used 48 albino rabbits (4 groups of 12 animals each), first group were control group (intravitreal saline solution), which were treated unilaterally every two hours with 2 drops of: Group II, pranoprofen (1 mg/ml). Group III, diclofenac (0.2 mg/ml). Group IV, flurbiprofen (0.3 mg/ml). We determined clinical signs of inflammation and protein concentration in the aqueous humor. The rabbits were sacrificed 24 hours after the endotoxin administration. RESULTS: In all treated groups we observed a significant reduction (p<0.05) in all studied parameter as compared with control group, except for ciliar hyperemia. Different treatment groups did not show differences. CONCLUSION: The antiinflammatory capacity of pranoprofen is comparable to other NSAIDs derived from propionic acid such as flurbiprofen, obtaining a good control of endotoxin-induced uveitis.

RESUMO

PURPOSE: To assess the effect of nicardipine (NCP) on fibroblast migration and proliferation, and its cellular toxicity. METHODS: In vitro wound repair was assessed in confluent fibroblast monolayer. Mechanical round wounds were performed in the monolayers and the cultures were incubated in fresh media plus NCP. The cell-free area was monitored after 0, 18, 24 and 48 hours. Groups of treatment: Group 1, Sham. Group 2, NCP 10(-4)M in the media. Group 3, NCP 7.5x10(-5)M. Group 4, NCP 5x10(-5)M. Group 5, NCP 2.5x10(-5)M. Group 6, NCP 10(-5)M. Group 7, NCP 10(-6)M. Group 8, NCP 10(-7)M. Group 9, NCP 10(-3)M. Each experiment consisted of three tests that were repeated four times. RESULTS: The fibroblast migration and proliferation was inhibited at 5x10(-5)M or higher doses. The proliferation after 48 hours with NCP 2.5x10(-5)M was statistically inferior to the control group and groups 7, 8, and 9. NCP 5x10(-5)M or higher doses showed cellular atypia and cell death. CONCLUSIONS: NCP effectively inhibits fibroblastic wound repair process at doses 2.5x10(-5)M and shows toxicity at doses over 5x10(-5)M.

RESUMO

OBJECTIVE: To evaluate the efficacy of clarithromycin alone in comparison with the combination of clarithromycin and cefuroxime in the treatment of nonhospitalized patients with community-acquired pneumonia (CAP) in a Mediterranean population. METHODS: CAP was defined as the acute onset of fever (>38 degrees C) with pulmonary opacity on chest roentgenogram. The American Thoracic Society (ATS) criteria (1993) were used to decide on patient hospitalization. Ninety subjects, of whom 53 (59%) were men, with a mean age (+/-SD) of 38+/-15 years, were randomized: 45 received clarithromycin 500 mg b.i.d. orally for 14 days (CL group), and 45 received clarithromycin plus cefuroxime 500 mg b.i.d. orally for 7 days (CLCE group). Patients were monitored with clinical, radiological, and laboratory controls at 3 and 21 days. There were no significant differences between the two groups with regard to demographic, clinical, physical and laboratory data. RESULTS: The mean time to defervescence was 2.4+/-1.4 and 2.4+/-1.5 days, respectively. Chest roentgenogram clearance was complete in all cases, without statistically significant differences in the time to resolution between both arms. Side effects were mild (no significant differences between groups): 5 patients in the CL group and 3 in the CLCE group showed gastrointestinal symptoms. Two patients (2.2%), both in the CLCE group, needed hospital admission during follow-up, but all 90 patients showed an excellent outcome. A causative agent was determined in 25 cases (28%). Legionella pneumophila, Streptococcus pneumoniae, and Mycoplasma pneumoniae were the most frequent pathogens. CONCLUSION: Empirical treatment of outpatient CAP with clarithromycin can be considered adequate in the Mediterranean area, independently of the microbiological etiology. ATS criteria for admitting patients with CAP are appropriate in this population.

RESUMO

BACKGROUND: The study was designed to evaluate blood pressure (BP) values related to left ventricular hypertrophy (LVH) in a group of never treated middle-aged hypertensive subjects. PATIENTS AND METHOD: Non-invasive ambulatory blood pressure monitoring (ABPM) and echocardiography were performed in 149 hypertensive patients (25-50 years old) with diastolic blood pressure (DBP) 90-114 mmHg. LVH was considered when left ventricular mass (LVM) was > 134 g/m2 in males and > 110 g/m2 in females. RESULTS: 43% of patients had LVH. Patients with LVH had higher clinic and ambulatory BP values. The greatest differences were in mean 24-h SBP (p = 0.001) and in 24-h DBP (p = 0.006). With respect to LVH, there were no differences between dippers and non-dippers, males or females, and circadian or BP variability. LVM was positively correlated with clinical DBP (p = 0.24), 24 h SBP (p = 0.41), pulse pressure (PP) (p = 0.36) and absolute BP variability (p = 0.23). Multiple regression analysis confirmed that 24-h SBP and sex where positively associated with LVH independent of others factors. The existence of 24-h SBP > 150 mmHg dramatically increased the risk of LVH (odds ratio [OR] = 9.2; CI 95%: 2.8-29.3; p = 0.002). CONCLUSIONS: The present study indicates that in never treated middle-aged essential hypertensive patients the principal factor related to the presence of LVH is the value of systolic blood pressure throughout a 24-h period.

RESUMO

OBJECTIVE: Stenotrophomonas maltophilia (SM) is a gram-negative bacillus whose incidence like nosocomial pathogen has been incremented in the last years, especially in immunocompromised patients, subjected to invasive procedures and those receiving broad-spectrum antimicrobial therapy. METHOD: We report 15 isolations of SM between 1994-1996. RESULTS: The criteria for SM infection were fulfilled by 9 patients (60%), and 6 patients (40%) were colonized. The mean age of the patient was 60 +/- 12 years. Major predisposing factors in infections included venous catheterization (100%), prior surgery (86%), residence in ICU (80%), prior antibiotic therapy (80%) and intubation (66%). The most common underlying disease were heart disease (60%), treatment with immunosuppressors and/or steroids (46%) and chronic lung disease (46%). Ten cases (66%) had polymicrobial culture. The mortality rate was 40%. Risk factors associated with fatal outcome included the following: chronic lung disease (p = 0.043), nasogastric catheterization (p = 0.01), urinary tract catheterization (p = 0.02), intubation (p = 0.04) and the presence of pneumonia or sepsis by SM (p = 0.02). The most active agents were colistina (100%), cotrimoxazol (71%) and ceftazidima (53%). The isolates were highly resistant to first and second-generation cephalosporins (100%) tetracyclines (86%), aztreonam (91%) and imipenem (71%). CONCLUSION: SM cause a wide range of clinical syndromes and is more likely to cause infection or colonization in patients who have underlying disease. Due to its inherent multiple-antimicrobial resistance, it would appear its potential as a nosocomial pathogen will continue to increase. Therapy of patients should include cotrimoxazole.

RESUMO

We reported a 66 year old woman diagnosed of cirrhosis secondary to VHC. A TIPS (transjugular intrahepatic portosystemic shunt) placement was used for the treatment of recurrent variceal hemorrhage and, a chyloperitoneum with hepatorenal syndrome developed after shunt occlusion. We discuss the pathological processes that might be responsible and the poor prognosis of this no reported complication.

RESUMO

African swine fever (ASF) virus induces immune cell alterations that may be detected by changes in peripheral blood cells phenotypic antigens and activation markers which were examined by flow cytometry, analyzing both cell proportion and/or expression intensity of superficial antigens. These studies were conducted in pigs with experimental acute of chronic ASF infection to determine whether changes among important surface activation markers and phenotypic antigens, and their correlative lymph node status, reflected similar or disparate aspects of immune pathology. In acute infection produced by virulent viruses, macrophage and B lymphocyte populations decreased in peripheral blood after a short activation period at the beginning of the infection. A significative decrease of interleukin 2 receptor (IL 2R) expression was also observed in those pigs. These variations correlated with lymph node cell depletion due to an intense lymphoid cell death by apoptosis, affecting mainly the B lymphocyte subpopulation as determined by immunohistochemistry. Nevertheless, pigs infected with an attenuated isolate undergoing chronic persistent infection, presented a distinct pattern of modification, according with a different clinicopathological evolution. Changes consisted in systemic immune activation coincident with the highest viremia titer, with an augmentation in CD8+ T lymphocyte, macrophage, and B cell populations, and MHC (major histocompatibility complex) antigens. Percentage elevation of circulating immune subpopulations was accompanied by cell accumulation with lymphoid hyperplasia but a conserved distribution of B lymphocytes in lymphoid organs of chronically infected pigs.

RESUMO

In a survey conducted from January to December, 1994, muscle tissues in 12 out of 22 slaughtered carabaos ages 8-17 years old and obtained from the Food Terminal Inc, Abbatoir in Laguna showed numerous white and creamy elliptic-shaped soft bodied macrocysts in the throat muscles. Microscopic examination of the throat and cardiac muscle tissues revealed the presence of fusiform-shaped microcysts. Our observations are consistent with previous reports incriminating Sarcocystis fusiformis as the most important etiologic agent of bubaline sarcocystosis in the country. In a survey of bovine sarcocystosis in muscle tissues of imported Australian cattle (Brahman Breed) and native cattle obtained from various slaughter houses in Manila and suburbs, prevalence rates of 17% (98/577) and 3% (1/31) were noted, respectively. Sarcocysts were predominant in skeletal muscles and to a lesser extent in cardiac, esophageal and diaphragm muscle tissues. Light microscopic examination of sarcocysts morphology suggests Sarcocystis cruzi (= Sarcocystis bovis), and Sarcocystis hominis (= Sarcocystis bovihominis) or Sarcocystis hirsuta (= Sarcocystis bovifelis) as the likely etiologic agents of bovine sarcocystosis in the country. Of the 225 swines examined, only muscle tissues from a 6-month old swine revealed very young sarcocysts (= metrocytes). A review of available documented studies on sarcocystosis suggests that to date, our findings may represent the first data on the prevalence of bovine and swine sarcocystosis in the Philippines.

RESUMO

Langerhans cell Histiocytosis or Histiocytosis X encompasses the syndromes of Letterer-Siwe disease, Hand-Schuller-Christian disease and eosinophilic granuloma. The localized disease usually consisted of isolated bone involvement as osteolytic areas. The isolated lymph node disease is uncommon. A case study of eosinophilic granuloma of lymph node in a 27 years-old woman who underwent several recurrences as lymphadenitis is presented. This case is presented in light of the cytologic, histologic and immunohistochemical findings of node-based eosinophilic granuloma and the favorable prognosis of this localized form treated with steroids.
