Review question / Objective: Does catheter ablation for scar-related monomorphic ventricular tachycardia improve outcomes (defined as any appropriate ICD therapy, appropriate ICD shocks, all-cause mortality, VT storm, cardiovascular mortality, cardiovascular hospitalizations, complications) in adult patients with ischemic or non-ischemic cardiomyopathy and implantable cardioverter-defibrillator? Condition being studied: Ventricular tachycardia in patients with structural heart disease is usually an arrhythmia using the myocardial scar as a substrate for reentry. It poses a risk of syncope and sudden cardiac death, especially in patients with reduced ejection fraction. Most antiarrhythmic drugs are of little value and their use is restricted in patients with LV systolic dysfunction. Catheter ablation is a viable option for the treatment of ventricular tachycardia. In patients with previous myocardial infarction the arrhythmogenic scar is located most frequently subendocardially and is readily accessible using endocardial approach, while in non-ischemic cardiomyopathy the scar is frequently located in the midmyocardial or subepicardial layers. This is the reason endocardial catheter ablation to be less effective in those patients and to more often necessitate epicardial approach.

Published: June 2022

COVID-19 is a severe and rapidly spreading respiratory disease that can be transmitted through airborne particles, emitted from cough. This study investigated the influence of underfloor air distribution (UFAD) and overhead air distribution on the diffusion of the coughed particles emitted from two infected patients in an isolation ward. Additionally, the study examined the performance of mounting retractable covers around the exhausts on minimizing the dispersion of the particles. A coupled Eulerian-Lagrangian approach is adopted by using a discrete random walk model. The effect of Brownian force, drag force with Cunningham slip correction factor, turbulence dispersion, Rosin-Rammler, and the breakup is considered in the respiratory airborne coughed particles simulation. The model has a good agreement with the experimental data. The results show that overhead air distribution (case 1) disperses the particles faster to the occupied zone due to the strong mixing between downward inlet airflow and indoor air accompanied by infectious particles. The usage of retractable covers (case 2) significantly minimized the diffusion of the particles inside the ward and their residence time. The particles quantity drops by 53, 98.62, and 99.94 % at 2.0, 10.0, and 120.0 s, respectively, compared to case 1. Case 2 shows the best efficient protection and inhaled air quality for the HCW in all the walking areas inside the room. The upward inlet air in underfloor air distribution (case 3) keeps particles floating for a while at a higher level near the ceiling exhausts, enhancing removal efficiency. Also, it has a slower lateral dispersion of the particles than in case 1. Underfloor air distribution minimized the number of particles by 30.0 % at 120.0 s, compared to overhead air distribution. Inlet air location significantly affects the diffusion of infectious particles in the indoor environment.

This study aims to investigate the feasibility of using a feedwater heaters system with coal-fired power plant. Furthermore, the influence evaluation of the different coal consumption on the coal-fired power plants in terms of power output and thermal efficiency improvements. As well, this study focuses on the effect of different feedwater heaters' numbers which caused the highest exergy destruction of the coal-fired power plants. For different values of the coal consumption, a parametric study was conducted to determine the efficiency of the coal-fired power plant. The results show that, when the coal consumption increases the power output will increases too. The slight decreases in the efficiencies are due to the small differences in how the mass flow rates of different streams increase. The exergy destruction was increased by about 16% when the consumption of fuel increases by 40 kg/s. It was observed that operating the coal-fired power plant at high coal consumption leads to reduce the effective ness of the feedwater heaters and increases the power output.

Fake news et théories du complot en période(s) pandémique(s)
Authors: Giry Julien
Published: June 2022

L’apparition et le développement de la pandémie de Covid-19 au début de l’année 2020 a donné lieu à la circulation dans l’espace public, en particulier numérique, de nombreux énoncés incertains voire douteux, parmi lesquels de véritables thèses conspirationnistes et fake news. Dès lors, l’enjeu de cet article est d’interroger, y com­pris dans leur profondeur historique, les conditions d’émergence et de circulation de ces énoncés performatifs qui constituent autant de mécanismes de régulation sociale et informationnelle alternatifs à la parole des autorités légitimes. Dans un premier temps, nous envisa­gerons comment la méconnaissance de la maladie nouvelle par les scientifiques, combinée à une communication des autorités politiques fluctuante et inaudible ainsi qu’un haut degré de défiance structurelle vis-à-vis des professionnels des médias et de la politique, a servi de « fenêtre d’opportunité » pour l’émergence de théories du complot et de fake news. Ensuite, nous verrons que ces dernières font largement écho à celles ayant déjà circulé lors des pandémies précédentes, depuis la fin du XIXe siècle au moins. Enfin, nous étudierons la manière dont ces énoncés ont circulé dans l’espace numérique, en particulier sur les réseaux sociaux.
L’université à la maison ou la plasticité de la vie privée en temps de Covid-19
Authors: Barats Christine , Wilhelm Carsten
Published: June 2022

La pandémie de Covid-19 a renforcé la place du numérique et des pratiques en ligne dans tous les secteurs d’activité. L’enseignement en ligne s’est ainsi généralisé, transformant le home office – parfois désiré – en lieu de télétravail forcé. Cette situation inédite interroge les frontières et définitions de la vie privée. Une enquête menée en France auprès d’enseignant.e.s de l’enseignement supérieur a permis de prêter attention à la multidimensionnalité de la vie privée et au concept de privacy en contexte, que ce soit au regard du choix des outils, de la présentation de soi ou du rapport aux autres. La situation d’enseignement en ligne a ainsi conduit à des renégociations des frontières de la vie privée, soulignant sa plasticité et la diversité des pratiques y afférents.
Exploring Convivial Conservation in Theory and Practice
Authors: Massarella Kate , Krauss Judith E. , Kiwango Wilhelm , Fletcher Robert
Published: June 2022

Convivial conservation has been put forward as a radical alternative to transform prevailing mainstream approaches that aim to address global concerns of biodiversity loss and extinction. This special issue includes contributions from diverse disciplinary and geographical perspectives which critically examine convivial conservation's potential in theory and practice and explore both possibilities and challenges for the approach's transformative ambitions. This introduction focuses on three issues which the contributions highlight as critical for facilitating transformation of mainstream conservation. First, the different ways in which key dimensions of justice — epistemic, distributive, and participatory and multi-species justice — intersect with the convivial conservation proposal, and how potential injustices might be mitigated. Second, how convivial conservation approaches the potential to facilitate human and non-human coexistence. Third, how transformative methodologies and innovative conceptual lenses can be used to further develop convivial conservation. The diverse contributions show that convivial conservation has clear potential to be transformative. However, to realise this potential, convivial conservation must avoid previous proposals’ pitfalls, such as trying to ‘reinvent the wheel’ and being too narrowly focused. Instead, convivial conservation must continue to evolve in response to engagement with a plurality of perspectives, experiences, ideas and methodologies from around the world.
Assessment of metabolic syndrome parameters in pediatric acute lymphoblastic leukemia survivors
Authors: Kartal Ömer , Gürsel Orhan
Published: June 2022

Objective:

This study aims to demonstrate the prevalence of metabolic syndrome parameters and to investigate their relationship with body mass index in pediatric acute lymphoblastic leukemia survivors.

Methods:

The cross-sectional study was conducted between January and October 2019 at the Department of Pediatric Hematology and comprised acute lymphoblastic leukemia survivors who had been treated between 1995 and 2016 and had been off treatment for at least 2 years. The control group included 40 healthy participants who were matched for age and gender. The two groups were compared in terms of various parameters (BMI [body mass index], waist circumference, fasting plasma glucose, HOMA-IR [Homeostatic Model Assessment–Insulin Resistance], etc.). Data were analyzed using Statistical Package for the Social Sciences (SPSS) 21.

Results:

Of the 96 participants, 56 (58.3%) were survivors and 40 (41.6%) were controls. Among the survivors, there were 36 (64.3%) men, whereas the control group had 23 (57.5%) men. The mean age of the survivors was 16.67 ± 3.41 years, whereas the mean age of the controls was 15.51 ± 4.2 years (P > 0.05). Multinomial logistic regression analysis showed that cranial radiation therapy and female gender were associated with overweight and obesity (P < 0.05). A significant positive correlation was found between BMI and fasting insulin, in survivors (P < 0.05).

Conclusion:

Disorders of the metabolic parameter were found to be more common among acute lymphoblastic leukemia survivors than among healthy controls.

Squamous cell carcinoma (SCC) has a good prognosis, while metastatic tumors have aggressive behavior. Immunotherapy has become a standard line of treatment in metastatic cancers; pembrolizumab has shown promising results and improved quality of life in recurrent and metastatic cancers. We report a case of recurrent SCC of the skin with extensive disease and a known case of human immunodeficiency virus. He completed standard lines of treatment and currently on immunotherapy. After 3 cycles of immunotherapy plus chemotherapy, he got a complete metabolic response. Our experience showed palliative benefits and increased quality of life.

Published: June 2022

Mucoepidermoid carcinoma (MEC) is a rare malignant thyroid neoplasm. Cases of MEC with papillary, insular, and anaplastic thyroid carcinoma have been reported. Here, we present a case of follicular carcinoma with extensive MEC-like differentiation. A 62-year-old female presented with complaint of thyroid swelling for 10 years. Cytological features were suggestive of follicular neoplasm. Contrast-enhanced computed tomography showed metastasis to lung and vertebrae. Salivary glands and breasts were normal on examination and imaging. Subtotal thyroidectomy with bilateral neck dissection surgery was performed. The specimen was submitted for histopathological examination. Microscopy showed features of follicular carcinoma with capsular and vascular invasion along with an additional MEC-like morphology. Follicular carcinoma with extensive MEC-like differentiation is a rare observation. Since the tumor was sparing salivary glands and breasts, we considered it as mucoepidermoid differentiation over a collision tumor. However, immunohistochemistry and molecular analysis were the limitations.

Thyroid gland blood supply is rich but it is not an open area for metastasis. Only 1%–3% of the neoplastic lesions seen in the thyroid are of extrathyroidal origin. Thyroid, lung, bone, lymph node metastasis were detected at the time of diagnosis in a 78-year-old woman with metastatic breast cancer. Control imaging was performed 3 months after hormone therapy was started. All lesions were regressed except thyroid lesion and neck lymph. Tru-cut biopsy was performed to the lesion in the thyroid. The result is consistent with breast cancer metastasis. With this breast cancer metastasis to thyroid case, we want to emphasize the differential diagnosis of neoplastic lesions in the thyroid is important in those diagnosed with malignancy. If there is clinical suspicion after a nondiagnostic thyroid sampling, repeated biopsies should be performed.

Published: June 2022

Background:

Saliva, a complex fluid secreted by the salivary glands within the oral cavity, is the first to interact with smoke while smoking. Nicotine in smoke causes structural and functional changes in the saliva, leading to a significant reduction in salivary flow.

Aim:

The present study was done to compare the salivary flow between reverse smokers, regular smokers, and non-smokers with the help of the Modified Schirmer Test (MST) to assess unstimulated saliva.

Materials and Methodology:

Ninety subjects were randomly divided into three groups; Group A (30) subjects who had the habit of reverse smoking daily for >6 months, Group B (30) subjects who had the habit of smoking daily for >6 months, and Group C (30) healthy, non-tobacco users. MST was done in the morning hours; they were not asked to eat/drink for 2 h before the procedure. Later, they were asked to raise their tongue, and the rounded end of Schirmer's strip was placed on the floor of the mouth. Wetting of the strip was recorded every 1, 2, and 3-minute intervals.

Results:

Data was recorded, and statistical analysis was done by the paired t-test. The mean value of salivary flow rate in reverse smokers per 3 minutes (19.73 ± 4.16) was less when compared to conventional smokers (22.53 ± 2.75) and healthy individuals (31.53 ± 2.90), with a significant P value of P < 0.0001.

Conclusion:

There was a significantly reduced unstimulated salivary flow rate in reverse smokers compared to conventional smokers and healthy individuals.
