Do hip hop ao ciberespaço: interações midiáticas em jovens da periferia

En el barrio de Guarapes, al oeste de Natal, RN, un grupo de jóvenes se organizó para buscar de paz en su vecindario. Encontraron en la cultura hip hop una forma de contar sus historias y trabajar en el fortalecimiento de su propio lugar. Formaron la Posse de Hip Hop Lelo Melodia (PH2LM) y hace cerca de dos años, instalaron la "Bodega Digital", una especie de telecentro que ofrecía acceso a computadoras e Internet, donde pudieron producir una gran cantidad de música, además del primer video del grupo musical, que está en el aire a través de la Internet. En un suburbio, los procesos de mediatización de la sociedad pueden adquirir su propia dinámica y seguir movimientos que van más allá de las barreras impuestas por el proceso contradictorio de la globalización. En esta investigación, se buscó establecer relaciones entre la acción político-cultural de los jóvenes de la Posse y su participación en los medios de comunicación, especialmente en la Internet. Al observar al grupo y en entrevistas episódicas con sus miembros, trazamos un mapa e interpretamos los movimientos de los jóvenes hacia el ciberespacio y en sentido inverso, cómo traen a la calle lo que conquistan allí. Hemos encontrado que, a pesar de todos los obstáculos, estos jóvenes encuentran vacíos y los aprovechan para asegurar su acceso a los medios de comunicación y su participación en el ciberespacio.

Steatosis and hepatic markers before and shortly after bariatric surgery

Background We present new findings on liver steatosis detected in a group of 20 morbidly obese patients who were reassessed shortly after bariatric surgery (BS) by assaying hepatic markers in their serum.Methods We assayed aspartate aminotransferase (AST), alanine aminotransferase, lactate dehydrogenase, alkaline phosphatase, gamma-glutamyl transferase (gamma-GT), cholinesterase, cholesterol, total protein, and albumin, and measured the weight and the body mass index (BMI) of patients, before and one and three months after surgery.Results There were significant reductions in BMI following surgery and also falls in transaminases and gamma-GT activities three months after BS. No changes occurred in other parameters between periods, except that cholesterol was above reference values before BS and fell to normal levels three months after BS.Conclusions We suggest that before undergoing surgery, the patients suffered from slight steatosis, while after BS the reduction in AST and gamma-GT indicated that this condition was corrected within three months. Moreover, these enzymes may be useful markers for excess fat in the liver.

A Single Intraoperative Sub-Tenon's Capsule Injection of Triamcinolone and Ciprofloxacin in a Controlled-Release System for Cataract Surgery

PURPOSE. To compare intraoperative injection of triamcinolone and ciprofloxacin in a controlled-release system (DuoCat) with prednisolone and ciprofloxacin eye drops after cataract surgery.METHODS. In this randomized, double-masked, controlled trial, a total of 135 patients undergoing cataract surgery were randomly allocated to two groups: 67 patients treated after surgery with prednisolone 1% and ciprofloxacin 3% eye drops four times daily (week 1), three times daily (week 2), twice daily (week 3), and once daily (week 4) and 0.3% ciprofloxacin drops four times daily (weeks 1 and 2), and 68 patients treated at the end of surgery with a sub-Tenon's injection of 25 mg triamcinolone and 2 mg ciprofloxacin in biodegradable microspheres. The patients were examined on postoperative days 1, 3, 7, 14, and 28. The main outcome measures were postoperative anterior chamber cell and flare, intraocular pressure (IOP), lack of anti-inflammatory response, and presence of infection.RESULTS. No significant differences were observed between the groups in anterior chamber cell (P > 0.14) and flare (P > 0.02) at any postoperative visits. The mean (99% confidence interval) differences in IOP between the prednisolone and triamcinolone groups on days 1, 3, 7, 14, and 28 were -0.4 mm Hg (-2.1 to 1.3), 0.0 mm Hg (-1.4 to 1.3), 0.0 mm Hg (-1.1 to 1.1), -0.2 mm Hg (-1.1 to 0.8), and -0.1 mm Hg (-1.1 to 0.9), respectively. No patient had a postoperative infection.CONCLUSIONS. One injection of DuoCat had a therapeutic response and ocular tolerance that were equivalent to conventional eye drops in controlling inflammation after cataract surgery.

Avaliação da capacidade de caminhar do portador de obesidade mórbida utilizando teste de caminhada de 6 minutos

Introduction: The ability to walk is impaired in obese by anthropometric factors (BMI and height), musculoskeletal pain and level of inactivity. Little is known about the influence of body adiposity and the acute response of the cardiovascular system during whole the 6-minute walk test (6mWT). Objective: To evaluate the effect of anthropometric measures (BMI and WHR waist-to-hip ratio), the effort heart and inactivity in ability to walk the morbidly obese. Materials and Methods: a total 36 morbidly obese (36.23 + 11.82 years old, BMI 49.16 kg/m2) were recruited from outpatient department of treatment of obesity and bariatric surgery in University Hospital Onofre Lopes and anthropometric measurements of obesity (BMI and WHR), pulmonary function, pattern habitual physical activity (Baecke Questionnaire) and walking capacity (6mWT). The patient was checking to measure: heart rate (HR), breathing frequency (BF), peripheral oxygen saturation, level of perceived exertion, systemic arterial pressure and duplo-produto (DP), moreover the average speed development and total distance walking. The data were analysed between gender and pattern of body adiposity, measuring the behavior minute by minute of walking. The Pearson and Spearmam correlation coefficients were calculated, and stepwise multiple Regression examined the predictors of walking capacity. All analyses were performed en software Statistic 6.0. Results: 20 obese patients had abdominal adiposity (WHR = 1.01), waist circumference was 135.8 cm in women (25) and 139.8 cm in men (10). Walked to the end of 6mWT 412.43 m, with no differences between gender and adiposity. The total distance walked by obesity alone was explained by BMI (45%), HR in the sixth minute (43%), the Baecke (24%) and fatigue (-23%). 88.6% of obese (31) performed the test above 60% of maximal HR, while the peak HR achieved at 5-minute of 6mWT. Systemic arterial pressure and DP rised after walking, but with no differences between gender and adiposity. Conclusion: The walk of obese didn´t suffers influence of gender or the pattern of body adiposity. The final distance walked is attributed to excess body weight, stress heart, the feeling of effort required by physical activity and level of sedentary to obese. With a minute of walking, the obeses achieved a range of intensity cardiovascular trainning

Desfechos clínicos e mortalidade de sujeitos submetidos à cirurgia bariátrica no Rio Grande do Norte

Introduction: Actually the obesity is a public health problem throughout the world. Bariatric surgery has been an efficient method of weight reduction body in severe obesity, reducing its associated effects and presenting low levels of immediate and late postoperative complications. In Brazil, bariatric surgery asa recent therapeutic that has been growing recently. Being Brazil a country with continental dimensions and with a huge diversity socioeconomic and cultural, it is essential to understand the reality of patients undergoing bariatric surgery in less economically privileged regions of Brazil. Objectives: To evaluate the epidemiological, clinical outcomes and mortality of patients undergoing videolaparoscopic bariatric surgery through the public health system in the Brazilian state of Rio Grande do Norte- Brazil. Methods: Observational descriptive study of a prospective, carried out from February 2009 to February 2011, the Clinic Obesity and Bariatric Surgery at Universitary Hospital Onofre Lopes - Federal University of Rio Grande do Norte (HUOL-UFRN). Anthropometric measures, comorbidity and deaths register were made in the postoperative period. Results: Seventy patients (54 women) with low income aged 22 to 63 years completed the study. We recorded the death of three patients during the study period. The results show significant decrease anthropometric parameters, especially in relation to body weight, waist circumference and hipin both sexes. Only Waist / Hip ratio showed no difference after intervention in male patients It had a resolution of comorbidities. No significant differences in reports of daily sleepiness and the snoring male patients. Conclusion: Our findings attest laparoscopic bariatric surgery as an effective method reducing weight and comorbidities in morbidly obese patients
