The Access Paradox: Media Environment Diversity and Coverage of Activist Groups in Japan and Korea

Celeste L. Arrington 동아시아연구원 2017 Journal of East Asian Studies Vol.17 No.1

To what extent is a diverse news media environment good for activists who seek attention for their cause? Scholars agree that activist groups depend on the media to reach policymakers and bystanders. Yet prior scholars have overlooked how factors that contribute to media environment diversity—including journalistic norms, market structures, outlets’ partisanship, and audiences’ news consumption habits—can have contradictory implications for activist groups. Disaggregating questions of gaining publicity from questions of the message and reach of coverage, this article shows that while pluralistic media environments are more accessible to activists, more homogeneous media environments help groups that manage to break into the mainstream news reach wider audiences with more coherent narratives. These findings challenge common assumptions about the news media in Japan and Korea. A paired comparison of hepatitis C-related activism in both countries demonstrate show the forces democratizing access to the media are paradoxically reducing the persuasive potential of publicity.

Purpose: To evaluate the preoperative and intraoperative risk factors for revision after artificial urinary sphincter (AUS) implantation in male patients with stress urinary incontinence (SUI). Methods: A retrospective analysis from a prospectively maintained database was performed. Male patients, with moderate-tosevere SUI, undergoing AUS implantation were included. All patients underwent placement of AMS 800. Cause of revision, type of revision, and time to revision were recorded. Multivariable analyzes were performed using a logistic regression to investigate the risk factors. Competing risk analysis according to Fine-Gray model was used to study time to event data. Results: A total of 70 patients were included. Revision surgery was performed in 22 of 70 patients (31.4%), after a median (interquartile range) time of 26.5 months (6.5–39.3 months). Overall, 19 of 22 repairs (86.4%) and 3 of 22 explants (13.6%) were recorded. Mechanical dysfunction, urethral erosion, urethral atrophy, and device infection were the causes of revision in 11 of 22 (50.0%), 6 of 22 (27.3%), 3 of 22 (13.6%), and 2 of 22 patients (9.1%). Vesicourethral anastomosis stenosis (P=0.02), urethral cuff size of 3.5 cm (P=0.029), and dual implantation (P=0.048) were independent predictors for revision. Vesicourethral anastomosis stenosis (P=0.01) and urethral cuff size of 3.5 cm (P=0.029) predicted a lower survival of the AUS. Conclusions: The vesicourethral anastomosis stenosis, urethral cuff size of 3.5 cm, and dual implantation are independent predictors for revision after AUS implantation. However, only the vesicourethral anastomosis stenosis and urethral cuff size of 3.5 cm predict a lower survival of AUS.

Portal vein arterialization following a radical left extended hepatectomy for Klatskin tumor: A case report

Celeste Del Basso,Roberto Luca Meniconi,Sofia Usai,Nicola Guglielmo,Marco Colasanti,Stefano Ferretti,Giovanni Battista Levi Sandri,Giuseppe Maria Ettorre 한국간담췌외과학회 2021 Annals of hepato-biliary-pancreatic surgery Vol.25 No.3

Portal vein arterialization (PVA) has been attracting attention for its role as a salvage inflow technique in various clinical applications. Initially performed in shunt surgery for portal hypertension, with the aim of preventing a decreased hepatic inflow, it is largely used in case of hepatic artery thrombosis in the transplantation domain or in the enlarged radical operations in case of hilar cancer invading the hepatic artery. A 62-year-old man underwent a left extended hepatectomy with hepatic bile duct resection and right Roux-en-Y hepaticojejunostomy for hilar cholangiocarcinoma. Computed tomography scan on postoperative day (POD) 5 revealed right hepatic artery pseudo-aneurysm, which was confirmed by an angiography. Stent placement was infeasible. Coiling of the pseudoaneurysm was associated with a risk of complete occlusion inducing critical liver failure. Since his general conditions were deteriorated, the patient underwent an emergency laparotomy. Hepatic artery reconstruction was impossible. Thus, a PVA was performed by anastomosing the ileocecal artery and vein. The intraoperative ultrasound showed satisfactory patency of the PVA with good portal flow in the absence of arterial flow. Doppler ultrasound on POD 15 showed that the cross-sectional area and blood flow of the portal vein were increased. The patient was discharged on POD 54 in good general condition. Hepatic artery disruption represents potentially lethal complications of hepatic, biliary, and pancreatic surgery. PVA may be a feasible therapeutic strategy to guarantee arterial inflow to the remnant liver. Although PVA is a salvage surgical procedure, increased portal flow should be controlled to avoid portal hypertension and liver fibrosis.

Neuropsychiatric Symptoms of Multiple Sclerosis: State of the Art

Celeste Silveira,Renato Guedes,Diana Maia,Rosário Curral,Rui Coelho 대한신경정신의학회 2019 PSYCHIATRY INVESTIGATION Vol.16 No.12

Multiple Sclerosis (MS) is a chronic disabling neuroinflammatory disease. Psychiatric manifestations have a high prevalence in MS patients and may worsen the illness progression and the patients’ quality of life (QoL). Depression is a highly prevalent condition in MS patients, associated with poorer adherence to treatment, decreased functional status and QoL, and increased suicide risk. Diagnosis and treatment of this disorder is challenging because of symptom overlap. Other prevalent psychiatric comorbidities are anxiety disorders, bipolar disorder, psychotic disorders, substance misuse and personality disorders. As the illness progresses, personality changes can happen, as well as affect abnormalities. Cognitive changes occur frequently in MS patients, and affect features like processing speed, attention, learning, memory, visual spatial capabilities, and some language deficits. Disease-modifying treatments may reduce cognitive impairment because of their container action on the brain’s lesion burden. Other QoL determinants such as fatigue, pain, sexual dysfunction, exercise, resilience and social support should be taken into account, in order to promote the individuals’ well-being. Further studies are needed in order to elucidate the effectiveness of pharmacotherapy and more neuroimaging studies are required to clarify the relationship between structural changes and psychiatric comorbidities.

Traditionally, the studies examining heuristics and biases in decision-making have used experimental designs to demonstrate violations of rationality. The objective of this study was to perform the replication of five classic cognitive biases with an alternative form of measurement. The problems and the response scales were adapted from the experimental tasks performed by Stanovich and West (2008) to measure five cognitive biases: base-rate, conjunction, framing, anchoring, and outcome. It is a quantitative study with a cross-sectional experimental design. The set of problems was applied to a sample of 440 participants, 72% of women (M age = 21.3, SD = 4.05). The comparison of the average scores of each pair of problems yielded a response form compatible with the predictions inferred from the theory of cognitive biases. In addition, it was possible to replicate the results of the experimental procedures on which this study was based. Future research should aim to determine personal and situational variables associated with different thinking biases and to develop interventions for eliminating these biases, thus optimizing performance in areas where the cost of errors may be too high.

To review the evidence of clinical efficacy of low-intensity extracorporeal shock wave therapy (Li-ESWT) for the treatment of erectile dysfunction (ED). A search on PubMed using Medical Subject Headings terms [((low intensity extracorporeal shockwave therapy) OR (Li-ESWT)) AND (erectile dysfunction)] was conducted in August 2022, to obtain studies on the use of Li-ESWT for the treatment of ED. Its success rate in terms of International Index of Erectile Function-5 (IIEF-5) score and Erection Hardness Score (EHS) improvement was recorded and analysed. A total of 139 articles were reviewed. Overall, 52 studies were included in the final review. 17 studies were on vasculogenic ED, 5 on post pelvic surgery ED, 4 specifically on ED in diabetic patients, 24 on non-specified origin ED and 2 on mixed pathophysiological origin ED. The mean age of patients was 55.87±7.91 (standard deviation) years and the duration of ED was 4.36±2.08 years. The mean IIEF-5 score went from 12.04±2.67 at baseline to 16.12±5.72, 16.30±3.26 and 16.85±1.63 respectively at 3, 6 and 12 months. The mean EHS went from 2.00±0.46 at baseline to 2.58±0.60, 2.75±0.46 and 2.87±0.16 respectively at 3, 6 and 12 months. Li-ESWT may be a safe and efficacy option for the treatment and cure of ED. Further studies are needed to assess which patients are more suitable for this procedure and which Li-ESWT protocol can lead to the best outcomes.

Aerodynamics and rain rivulet suppression of bridge cables with concave fillets

Burlina, Celeste,Georgakis, Christos T.,Larsen, Soren V.,Egger, Philipp Techno-Press 2018 Wind and Structures, An International Journal (WAS Vol.26 No.4

In this paper, the aerodynamic performance of two new cable surfaces with concave fillets (strakes) is examined and compared to plain, dimpled and helically filleted surfaces. To this end, an extensive wind-tunnel campaign was undertaken. Different samples with different concave fillet heights for both new surfaces were tested and compared to traditional surfaces in terms of aerodynamic forces (i.e. drag and lift reduction) and rain-rivulet suppression. Furthermore, flow visualization tests were performed to investigate the flow separation mechanism induced by the presence of the concave fillet and its relation to the aerodynamic forces. Both new cable surfaces outperformed the traditional surfaces in terms of rain-rivulet suppression thanks to the ability of the concave shape of the fillet to act as a ramp for the incoming rain-rivulet. Furthermore, both new surfaces with the lowest tested fillet height were found to have drag coefficients in the supercritical Reynolds range that compare favorably to existing cable surfaces, with an early suppression of vortex shedding.
