Dirigentas de campamento y actividad mediática: Más allá de internet

__RESUMEN__ El debate en torno al carácter activo de las audiencias contemporáneas tiende a centrarse en las nuevas tecnologías de comunicación y en las posibilidades de producción de contenido que ellas ofrecen. Este artículo propone, en cambio, atender al carácter político de ciertas actividades mediáticas y a factores no-tecnológicos. Específicamente, identificamos la llamada cultura promocional como un impulso importante para influir —y no directamente producir— los contenidos en los medios. Ilustramos este enfoque a través de un caso de estudio sobre la relación entre dirigentas de campamentos y los medios de comunicación en Chile. Estas mujeres interactúan con los medios tradicionales, no digitales, motivadas por la necesidad de reivindicar su imagen y promocionar sus demandas. Argumentamos que el estudio de las actividades de las audiencias en una sociedad neoliberal como la chilena debe considerar que las estrategias promocionales no son el privilegio de ciertos grupos sociales, sino que están presentes de un modo cada vez más generalizado en la sociedad. __ABSTRACT__ Discussions about the active character of contemporary audiences tend to be centered on new communication technologies and on the possibilities of content production offered by these technologies. This article, in contrast, proposes that we pay attention to the political character of certain media activities and to non-technological factors that influence the changing relation between audiences and media. Specifically, we focus on promotional culture as an important drive for activities aimed at influencing—and not directly producing—media content. This approach is illustrated through a case study about the relationship between female slum community leaders and the media in Chile. These women interact largely with traditional rather than digital media, motivated by the need to challenge the image of them proposed by those media, and promote their demands. We argue that the study of audience participation in a neoliberal society like Chile must recognize promotional strategies as not exclusive of certain social groups, but as increasingly widespread throughout society

Cutaneous manifestations of spondyloarthritis

Spondyloarthritis comprises a group of inflammatory rheumatic disorders with a genetic predisposition involving multiple genes that interact with environmental factors. The skin manifestations of spondyloarthritis are diverse, particularly psoriatic arthritis related to the overexpression of inflammatory cytokines such as TNF, IL-6, IL-12, IL-2 and IFN-g; this psoriatic dermatitis is a common skin feature of spondyloarthritis. Spondyloarthritis mainly affects the spine, sacroiliac joints, ligaments and other tissues. Psoriatic lesions are erythematous plaques covered with silvery whitish scales distributed on the scalp, elbows, knees, trunk and gluteus creases, and the fingernails are frequently involved. Individuals with reactive arthritis and Crohn’s disease may exhibit psoriasiform dermatitis and other manifestations including ocular inflammation, oral ulceration, erythema nodosum and/or thrombophlebitis. In the case of reactive arthritis, male patients may exhibit circinate balanitis and keratoderma blennorrhagica. In summary, dermatological manifestations of spondyloarthritis represent clinical clues and a unique scenario to explore the related pathophysiology and therapeutic approaches

Severe Cases of Pandemic (H1N1) 2009 in Children, Germany

In a hospital-based observational study in Germany, we investigated children admitted to pediatric intensive care units and deaths caused by confirmed pandemic (H1N1) 2009 to identify risk factors and outcomes in critically ill children. Ninety-three children were eligible for our study, including 9 with hospital-acquired infections. Seventy-five percent had underlying chronic medical conditions; neurodevelopmental disorders were most prevalent (57%). The proportion of patients having >1 risk factor increased with age in years (odds ratio 1.21, p = 0.007). Of 15 deaths, 11 occurred in a pediatric intensive care unit (case-fatality rate 12%, 95% confidence interval 6%–21%). Only 9% of the children had been vaccinated against pandemic (H1N1) 2009; all survived. Our results stress the role of underlying risk factors, especially neurodevelopmental disorders, and the need for improving preventive measures to reduce severe disease and adverse outcomes of pandemic (H1N1) 2009 in children

Nowcasting pandemic influenza A/H1N1 2009 hospitalizations in the Netherlands

During emerging epidemics of infectious diseases, it is vital to have up-to-date information on epidemic trends, such as incidence or health care demand, because hospitals and intensive care units have limited excess capacity. However, real-time tracking of epidemics is difficult, because of the inherent delay between onset of symptoms or hospitalizations, and reporting. We propose a robust algorithm to correct for reporting delays, using the observed distribution of reporting delays. We apply the algorithm to pandemic influenza A/H1N1 2009 hospitalizations as reported in the Netherlands. We show that the proposed algorithm is able to provide unbiased predictions of the actual number of hospitalizations in real-time during the ascent and descent of the epidemic. The real-time predictions of admissions are useful to adjust planning in hospitals to avoid exceeding their capacity

Risk Factors for Severe Cases of 2009 Influenza A (H1N1): A Case Control Study in Zhejiang Province, China

Few case control studies were conducted to explore risk factors for severe cases of 2009 influenza A (H1N1) with the mild cases as controls. Mild and severe cases of 2009 influenza A (H1N1), 230 cases each, were randomly selected from nine cities in Zhejiang Province, China, and unmatched case control study was conducted. This study found that it averagely took 5 days for the severe cases of 2009 influenza A (H1N1) to start antiviral therapy away from onset, 2 days later than mild cases. Having chronic underlying diseases and bad psychological health combined with chronic underlying diseases were two important risk factors for severe cases, and their OR values were 2.39 and 5.85 respectively. Timely anti-viral therapy was a protective factor for severe cases (OR = 0.35, 95% CI: [0.18–0.67]). In conclusion, psychological health education and intervention, as well as timely anti-viral therapy, could not be ignored in the prevention, control and treatment of 2009 influenza A (H1N1)

Fasting plasma glucose is an independent predictor for severity of H1N1 pneumonia

<p>Abstract</p> <p>Background</p> <p>The pandemic influenza A (H1N1) virus emerged during 2009 and has spread worldwide. This virus can cause injuries to the lungs, liver, and heart. However, data regarding whether this influenza virus can affect pancreatic islets are limited. We investigated the effects of influenza A (H1N1) pneumonia on fasting plasma glucose (FPG) and islet function, and evaluated possible correlations between biochemical test results and the severity of H1N1 pneumonia.</p> <p>Methods</p> <p>We performed a retrospective analysis of patients either diagnosed with or suspected of having H1N1 pneumonia who were admitted to our hospital in 2009. Possible associations between FPG levels and H1N1 virus infection were assessed by logistic regression. Correlation and regression analyses were used to assess relationships between FPG and biochemical test results. Associations between admission days and significant data were assessed by single factor linear regression. To evaluate effects of H1N1 on pancreatic β-cell function, results of a resistance index (homa-IR), insulin function index (homa-β), and insulin sensitivity index (IAI) were compared between a H1N1 group and a non-H1N1 group by t-tests.</p> <p>Results</p> <p>FPG was significantly positively associated with H1N1 virus infection (OR = 1.377, 95%CI: 1.062-1.786; p = 0.016). FPG was significantly correlated with AST (r = 0.215; p = 0.039), LDH (r = 0.400; p = 0.000), BUN (r = 0.28; p = 0.005), and arterial Oxygen Saturation (SaO₂; r = -0.416; p = 0.000) in the H1N1 group. H1N1 patients who were hypoxemic (SaO₂<93%) had higher FPG levels than those who were not hypoxic (9.82 ± 4.14 vs. 6.64 ± 1.78; p < 0.05). FPG was negatively correlated with SaO₂in the H1N1 group with hypoxia (SaO₂<93; r = -0.497; p = 0.041). SaO₂levels in patients with high FPG levels (≥7 mmol/L) were significantly lower than those of H1N1 patients with low FPG levels (<5.6 mmol/L). There were no significant differences in homa-IR, homa-β, or IAI between the H1N1 and non-H1N1 groups after adjusting for age, sex, and BMI.</p> <p>Conclusions</p> <p>FPG on admission could be an independent predictor for the severity of H1N1 pneumonia. Elevated FPG induced by H1N1 pneumonia is not a result of direct damage to pancreatic β-cells, but arises from various factors' combinations caused by H1N1 virus infection.</p
