Formulary Management of Biologics in Plaque Psoriasis
Authors: Vannabouathong Chris , Dyrda Peter
Published: March 2023

Unlike the new-generation biologics (interleukin [IL]-17 and IL-23 inhibitors), all old-generation biologics (anti–tumour necrosis factor [TNF] and anti–IL-12/23 biologics) for plaque psoriasis (PsO) have now lost their exclusivity status and most were launched prior to the pan-Canadian Pharmaceutical Alliance. In addition, biosimilar versions of the old-generation biologics have had limited uptake and delayed launches in Canada spanning multiple years, suggesting a significant opportunity cost paid for these drugs after loss of exclusivity.

Modern clinical evidence, which is more rigorous than the evidence supporting the old-generation drugs and includes head-to-head trials comparing IL-17 and IL-23 inhibitors with anti-TNF and anti–IL-12/23 biologics, have demonstrated greater efficacy with the new-generation biologics.

In Canada, despite access to newer and more efficacious treatments, physicians continue to prescribe old-generation drugs to patients newly initiating a biologic for PsO (25% of patients in 2020), and the new-generation biologics are also less costly on an average per patient basis at list price compared with the most utilized old-generation biologic (ustekinumab).

Public payers have spent $28 million (at list price) on biologics initiated for PsO beyond their loss of exclusivity from 2016 to 2020 ($600 million for biologics initiated for any indication), and that figure is likely much higher today. Notably, some IL-17 biologics will lose data protection within the next 2 years, which will further increase this opportunity cost.

It is prudent that decision-makers review the place in therapy of biologics for PsO. Based on the findings of this report, the policy recommendation is to assess the clinical and economic value of old-generation biologics in the context of current evidence standards in PsO. The promotion of the use of new-generation biologics should be considered by payers to support the appropriate use of biologics in PsO, which would improve patient outcomes with budget savings or neutrality (assuming no confidential pricing agreements with the old-generation biologics) versus the status quo.
Improving Arctic sea ice thickness retrieved from CryoSat-2: A comprehensive optimization of a retracking algorithm, radar penetration rate, and snow depth

Published: March 2023

Abstract. The Arctic sea ice thicknesses retrieved from the CryoSat-2 satellite are significantly influenced by sea ice surface roughness, snow backscatter, and snow depth on the sea ice. This study is the first to improve the retrieval of sea ice thickness from CryoSat-2 data derived by the Alfred Wegener Institute (AWI CS2) through applying a comprehensive optimization of an improved retracking algorithm, corrected radar penetration rate, and new snow depth. The radar freeboard data was obtained from the improved retracking algorithm of the Lognormal Altimeter Retracker Model (LARM). The radar penetration rates were corrected to 0.77 for first-year ice (FYI), 0.96 for multi-year ice (MYI), and 0.91 for all ice types. The new snow depth data was derived from the Chinese satellite Feng Yun-3B with the MicroWave Radiometer Imager (FY3B/MWRI). Three individual and one combined optimization cases were created by focusing on the retracking algorithm, radar penetration rate, and snow depth, which were validated with in situ observations collected from the National Aeronautics and Space Administration Operation IceBridge (OIB), Ice Mass Balance buoys (IMB), CryoSat Validation Experiment (CryoVEX), and Alfred Wegener Institute IceBird Program (AWI IceBird). The assessment results showed that all the optimization cases had the ability to effectively improve the sea ice thickness, with similar correlation coefficients. In the validation with the four kinds of observed data, the optimization cases reduced the RMSE of AWI CS2 up to 0.23 m (25.0 %), 0.27 m (29.7 %), 0.26 m (25.5 %), and 0.22 m (23.9 %). The improved sea ice thickness retrieval retained the major distribution patterns generated by AWI CS2, but generally showed thinner sea ice thickness. In particular, in the MYI region, the difference in thickness became increasingly evident from fall to spring. The differences in the variation trend between the optimization cases and AWI CS2 were significant in some coastal regions and the central Arctic. The experiments revealed that the radar penetration rate calculation was more sensitive to sea ice density than to snow density. The sensitivity experiments suggested that the snow depth of TOPAZ4, in addition to that of FY3B/MWRI, was also applicable in improving the retrieval of sea ice thickness. The updated scheme of sea ice densities (FYI = 925 kg m−3 and MYI = 902 kg m−3) can be combined with the use of comprehensive optimization to improve the retrieval of sea ice thickness. This successful optimization provided new insights into improving the sea ice thickness retrieved from CryoSat-2 and helped to further understand and quantify the spatiotemporal variations of sea ice thickness.
New Records of Species Taeniopteryx hubaulti Aubert, 1946 and Taeniopteryx schoenemundi (Mertense, 1923) (Plecoptera: Taeniopterygidae) in Serbia

Published: March 2023

Species Taeniopteryx hubaulti Aubert, 1946 and T. schoenemundi (Mertense, 1923) have been emphasized as endangered or vulnerable species in several European countries due to their local and limited distribution. More intensive research of these species on the territory of Serbia was conducted from 2011 to 2022. Taeniopteryx hubaulti was registered in seven localities. Five of these localities (Brusnička and Jerma rivers, the spring of the Raška River, and two localities on Grza River, spring and tufa barriers) were recorded as new sites of this species in Serbia. Two localities (Barska River and Lisinski Stream) had already been known from previous studies. The species T. schoenemundi was recorded in four new localities (Dulenska, Visočica, Temštica, and Trnavska rivers). Both species were found in waters with high oxygen concentration, relatively uniform low water temperature, and variable values of hardness, electrical conductivity, and pH values, with a small amount of inorganic nutrients. Considering the rare occurrence and prominent importance of these species as biological indicators of water quality and climate change, their findings have a great deductive value. This research represents an important contribution to the insight into the distribution of T. hubaulti and T. schoenemundi species.

Published: March 2023

To systematically study the quantitative relationship between natural enemies and pests, this paper used grey relational analysis method, angular cosine coefficient method, fuzzy similarity priority ratio method and correlation coefficient method to analyze the closeness of the quantitative relationship between natural enemies and Empoasca onukii Matsuda in “Anjibaicha”, “Huangshandayezhong” and “Longjing 43” tea plantations. The conclusions obtained by the grey relational analysis method were used as a criterion to compare the sum of the rankings of the top three natural enemies, Plexippus paykulli, Tetragnatha squamata and Ebrechtella tricuspidata, thus comparing and discussing the similarities and differences between the conclusions obtained by the four research methods. The angular cosine coefficient method and grey relational analysis method yielded no major differences in conclusions, followed by the correlation coefficient method, with the fuzzy similarity priority ratio method yielding more varied results. According to the ranking analysis of the close relationship between the number of E. onukii and its natural enemies, Tetragnatha squamata, Hylyphantes graminicola and Ebrechtella tricuspidata are the first three natural enemies closely related to the number of E. onukii. This paper is an attempt to compare the consistency of research results of various research methods, which provides a reference for selecting research methods in analyzing the quantitative relationship between natural enemies and pests.

Authors: Brunton Steven L.
Published: March 2023

Turbulent fluid dynamics are often too complex to model every detail. Instead, we tend to model bulk quantities and low-resolution approximations. To remain physical, these reduced approximations of the Navier-Stokes equations must be 'closed', and turbulence closure modeling is one of the most important topics in high-performance computing and scientific computing. This video describes several leading approaches, including the Reynolds averaged Navier Stokes (RANS) equations and large eddy simulations (LES).

We also discuss how to enforce partially known physics, such as energy conservation in incompressible fluid flows, by constraining the sparse least squares regression.
Discrepancy Modeling with Physics Informed Machine Learning
Authors: Brunton Steven L.
Published: March 2023

This video describes how to combine machine learning with classical physics models to correct for discrepancies in the data (e.g., from nonlinear friction, wind resistance, etc.). Several examples are covered, from modern robotics, to classical connections with Galileo v. Aristotle, and Kepler v. Ptolemy. The examples in this video highlight work and discussions with Prof. Nathan Kutz, especially connections to classical scientific discoveries.

Turbulence: Reynolds Averaged Navier-Stokes (Part 1, Mass Continuity Equation)
Authors: Brunton Steven L.
Published: March 2023

One of the most common strategies to model a turbulent fluid flow is to attempt to model the average, or mean flow field, by expanding the velocity field into an average and a fluctuating component. This video introduces this idea of 'Reynolds averaging' and shows how to obtain a mass continuity equation for the mean flow.

Authors: Nascimento Vagner Ferreira do , Piber Ronaldo Souza , Britis Rayssa Ferreira , Riegel Fernando , Unicovsky Margarita Ana , Terças-Trettel Ana Cláudia Pereira , Luis Margarita Antonia Villar
Published: March 2023

Objetivo: conhecer as opiniões de idosos acerca da vacina anticovid e sua possível recusa. Metodologia: trata-se de estudo exploratório e qualitativo, realizado em um município de pequeno porte, do extremo Norte de Mato Grosso, Brasil. A coleta de dados ocorreu em março de 2021, por meio de entrevista semiestruturada. Para a análise dos dados, utilizou-se o software ATLAS.ti®. Resultados: a maioria dos idosos demonstrou aceitação e desejo em ser imunizada, porém aqueles com baixa escolaridade apresentaram maior rejeição à vacina, os quais foram percebidos pelos demais idosos como irresponsáveis. Os participantes mencionam que todos possuem o direito de escolha. Conclusões: apesar de os idosos terem opinado positivamente sobre a vacina, ações educativas, principalmente junto àqueles com baixa escolaridade, devem ser intensificadas, a fim de que o comportamento de recusa, caso prevaleça mesmo após diálogos e esclarecimentos, não influencie terceiros e coloque em risco a saúde da comunidade.

Pengabdian Kepada Masyarakat (PKM) merupakan salah satu kegiatan wajib bagi dosen berdasarkan Tri Dharma Perguruan Tinggi. Artikel ini membahas mengenai perlunya mengadakan pelatihan berkaitan dengan pengenalan konsep pembangunan video game. Hal ini dianggap perlu karena melihat banyaknya peluang yang terbuka di industri video game. Ditambah lagi dengan fakta bahwa Indonesia merupakan pangsa pasar video game terbesar di Asia Tenggara. Pengembang video game lokal bahkan hanya menguasai 0.4% pangsa pasar di Indonesia. Disisi lain, Indonesia memiliki kurikulum pendidikan yang bertujuan untuk menyiapkan sumberdaya manusianya untuk menguasai kemampuan industri dengan pendidikan setingkat Sekolah Menengag Atas (SMA) yang disebut Sekolah Menengah Kejuruan (SMK). Motivasi yang kuat untuk menguasai kemampuan industri pada pelajar SMK menjadikan SMK menjadi target yang cocok untuk diberikan pembekalan mengenai pembangunan video game. Maka dari itu, Institut Teknolgi dan Bisnis Kalbis serta SMK Sint Joseph bermitra untuk mengadakan pelatihan ini. Dari kegiatan PKM yang telah dilakukan, kegiatan ini memiliki hasil evaluasi yang sangat baik berdasarkan kuisioner yang diisi peserta. Berdasarkan antusiasme dan saran dari peserta membuat pelatihan ini juga layak untuk diadakan kembali dengan materi pembelajaran yang baru dan lebih mendalam.

ABSTRACT: Village development plays an important role for the advancement of a nation because it is an inseparable part of regional and national development. An Islamic youth movement organization whose majority of its members are young people is part of the community that should participate in village development. To foster this spirit, a village driving cadre school was held. The method used in carrying out this community service is socialization and discussion. The stages of implementing village driving cadres are the stages of planning activities, implementation activities, and evaluations. The results of this activity are expected to increase youth awareness in exploring village potential and play an active role in village development.

Life Is Not a Machine or a Ghost: The Naturalistic Origin of Life’s Organization and Goal-Directedness, Consciousness, Free Will, and Meaning
Authors: Enright Marsha Familaro
Published: March 2023

Due to a widespread belief in mechano-reductionism, most intellectuals reject the idea that nonconscious living beings act toward goals. Proposing otherwise is mostly rejected as unscientific anthropomorphizing or necessitating appeals to a supernatural power. This false dichotomy has stymied biology and its related sciences. Herein, I present a new naturalistic gestalt on the nature of life—one based on facts and evidence. It incorporates Ludwig von Bertalanffy’s and Arthur Koestler’s theories of systems and hierarchies with the ideas of Aristotle, Hans Jonas, and Ayn Rand, to identify fundamental formulations on the nature of life, consciousness, free will, and meaning.

A review of Bixa orellana L. (Annatto) leaves as medicinal resource: Use in the population as complementary medicine, phytotherapeutic action and quality parameters
Authors: Molina-Romani Sonia , Bonilla-Rivera Pablo , de Albuquerque Ricardo Diego
Published: March 2023

Bixa orellana, known as Annato or Achiote, is a species popularly used in various countries of America as a dye and medicine. Its leaves possess several biological activities and are commonly marketed as filters. However, despite some ethnomedicinal and pharmacological studies with Bixa orellana leaves having been published, there is a lack of review articles that collect this information. In addition, the few studies about the quality parameters of these filters must be addressed jointly so that the usefulness of existing information can be better addressed in the discussion of commercial regulation. In this way, this review aims to compile systematically useful information about the medicinal use and pharmacology of B. orellana leaves, in addition to channeling the studies on the quality parameters of filters, which in turn can define the quality, efficacy and safety of the marketed products. As a result of the review, the searches showed that the leaves of B. orellana are traditionally used for various purposes, including treatment of headache, bronchitis, and inflammation, in addition to using as a diuretic, analgesic, antiophidic, among others. These findings were corroborated by pharmacological studies, which also point to other biological activities such as antioxidant, antimicrobial, anti-inflammatory, neurodepressant and gastrointestinal modulator through the administration of leaf extracts. Finally, stability and extraction yield studies were also important in providing data for implementing quality control of B. orellana products.

Traumatic dental injury (TDI) is a public health problem with high prevalence and incidence rates. Appropriate intervention can significantly reduce subsequent complications of these events. This case report describes the clinical interventions to manage a patient with traumatic maxillary incisor with extrusive dislocation . The intervention aimed to preserve pulpal vitality and ensure periodontal maintenance to the highest possible degree. In this article, the patient referred to the ,, Spitalul Clinic Republican pentru Copii „Emilian Coțaga””with dental trauma who suffered extrusive dislocation of maxillary lateral incisor d.12 . The patient reported that he suffered a direct blow to the OMF region. The case will document the clinical approach taken for d.12 permanent maxillary incisor with extrusive dislocation in a 17-yearold boy. The proposed procedures involved repositioning of the tooth, by digital pressure and stabilization using a rigid splint namely with the help of fixed orthodontic straight Muspring Ni-Ti appliance with 14mm diameter for 3-4 weeks ,plus bracket refixation on the tooth surface. X-rays are useful to visualize the displacement of the tooth in the alveolus and its repositioning. In this case we will use the OPG paraclinical examination as a diagnostic source. However, long-term clinical and radiological follow-up (3,6,12 months) is necessary to prevent and detect early any complications that may arise from extrusive dislocation. Lacunar, apical or superficial root resorption, pulpal necrosis may occur from which the treatment tactics should be modified, respectively, and the rehabilitation time will be different.
