Digital literacy linked to engagement and psychological benefits among breast cancer survivors in Internet-based peer support groups
© 2019 John Wiley & Sons Ltd Objective: Internet-based peer support groups (ISGs) represent an innovative, scalable approach to addressing information and support needs of cancer survivors. However, this innovation may not benefit survivors equally due to population variance in digital literacy. This study examined how digital literacy influences level of engagement in and psychological benefits from participating in ISGs for breast cancer (N = 183). Methods: Secondary analysis of data from a randomised trial of ISGs that included behavioural measures of engagement, subjective ratings and psychological distress symptoms. Results: Digital literacy was positively related to education level (p =.005). Relative to women with high digital literacy, those with lower digital literacy were more likely to report difficulties using the ISG and to value the user's guide and facilitator assistance (all p's <.05). Digital literacy was negatively correlated with computer anxiety pre-intervention, distress before and after online chat during the intervention and post-intervention depressive symptoms (all p's <.05). Conclusion: Low digital literacy is associated with computer anxiety and barriers to ISG use, as well as distress during and after ISG use. Digital literacy must be taken into account when designing or delivering innovative digital interventions for cancer survivors
Collisional cross sections and momentum distributions in astrophysical plasmas: dynamics and statistical mechanics link
We show that, in stellar core plasmas, the one-body momentum distribution
function is strongly dependent, at least in the high velocity regime, on the
microscopic dynamics of ion elastic collisions and therefore on the effective
collisional cross sections, if a random force field is present. We take into
account two cross sections describing ion-dipole and ion-ion screened
interactions. Furthermore we introduce a third unusual cross section, to link
statistical distributions and a quantum effect originated by the
energy-momentum uncertainty owing to many-body collisions, and propose a
possible physical interpretation in terms of a tidal-like force. We show that
each collisional cross section gives rise to a slight peculiar correction on
the Maxwellian momentum distribution function in a well defined velocity
interval. We also find a possible link between microscopical dynamics of ions
and statistical mechanics interpreting our results in the framework of
non-extensive statistical mechanics.Comment: 8 page
Tapinarof Cream 1% Once Daily for the Treatment of Plaque Psoriasis: Case Photography of Clinical Outcomes from Three Phase 3 Trials
Tapinarof cream 1% (VTAMA(®); Dermavant Sciences, Inc.) is a non-steroidal, topical, aryl hydrocarbon receptor agonist approved by the US Food and Drug Administration (FDA) to treat plaque psoriasis in adults and under investigation for the treatment of psoriasis in children down to 2 years of age, and for atopic dermatitis in adults and children down to 2 years of age. The PSOARING phase 3 clinical trial program evaluated tapinarof cream 1% once daily (QD) in adults with mild to severe plaque psoriasis for up to 52 weeks (NCT03956355, NCT03983980, NCT04053387).
Here we present case photography documenting outcomes in the PSOARING trials. Cases illustrate various outcomes across different body areas, including responses meeting the formal FDA-mandated regulatory endpoint of a Physician Global Assessment (PGA) score of 0 (clear) or 1 (almost clear) and a decrease of at least 2 points from baseline at week 12, meaningful clinical improvement not meeting this formal endpoint, patient-reported outcomes, and pre-specified adverse events of special interest (AESIs). Tapinarof cream 1% QD demonstrated rapid and highly statistically significant efficacy, with improvements in disease activity and quality of life. In addition, a high rate (40.9%; n = 312/763) of complete disease clearance (PGA = 0) was achieved, and improvements exceeding National Psoriasis Foundation treatment goals were demonstrated. After first achieving complete disease clearance (PGA = 0), patients treated with tapinarof experienced an approximately 4-month remittive effect off therapy. Incidence and severity of folliculitis and contact dermatitis AESIs were generally mild or moderate, localized to the site of application, and associated with low discontinuation rates. Medical images are of importance in trials of dermatologic therapies to inform clinical decision-making and enhance patient assessment. Tapinarof cream 1% QD is efficacious and well tolerated in patients with mild to severe plaque psoriasis, with clinically relevant improvements seen early in the course of treatment.

Исследование методов государственного регулирования цен и издержек системы здравоохранения на лекарственные препараты в Великобритании
Objective: analysis of state regulation of prices and costs for the purchase of medicines (drugs) in the United Kingdom (UK), and proposal development to improve the processes of state regulation of manufacturers’ marginal registered prices of medicines included in the list of vital and essential drugs approved in the Russian Federation.Material and methods. Analysis of the structure of state regulation of prices and costs for the procurement of drugs was carried out based on information contained in the regulatory legal documents of the UK Government, health services and technical regulation, and data provided in systematic reviews and articles.Results. A key feature of regulation in the UK is maximizing the efficiency of health care costs based on the principles of digitization, long-term planning and health technology assessment in pricing. Government regulation of costs is focused on the patent-protected drug segment. Providers of such medicines fall under the Voluntary or Statutory Scheme and are required to make payments in the form of a fixed percentage of sales to the Department of Health and Social Care. Certain drug segments are exempt from payments to stimulate innovative development of the pharmaceutical industry and accelerate market access for new therapies. As practice shows, the Voluntary Scheme is more profitable for most companies. Regulation in the segment of reproduced drugs is carried out by free-market mechanisms and the antimonopoly service.Conclusion. The analysis revealed the mechanisms and key features of the methods of state regulation of prices and costs of the health care system for the procurement of drugs, identified best practices that are promising for adaptation to improve the state regulation of prices in the Russian Federation. Цель: анализ государственного регулирования цен и издержек на закупку лекарственных препаратов (ЛП) в Великобритании, а также разработка предложений по совершенствованию процессов государственного регулирования предельных зарегистрированных цен производителей на препараты, включенные в перечень жизненно необходимых и важнейших ЛП, утвержденный в Российской Федерации.Материал и методы. Анализ структуры государственного регулирования цен и издержек на закупку ЛП проведен на основании сведений, содержащихся в нормативных правовых документах Правительства Великобритании, служб здравоохранения и технического регулирования, а также информации, представленной в систематических обзорах и статьях.Результаты. Ключевой особенностью регулирования в Великобритании является максимизация эффективности издержек здравоохранения на основе принципов цифровизации, долгосрочного планирования и оценки технологий здравоохранения при ценообразовании. Государственное регулирование издержек сконцентрировано на сегменте ЛП, находящихся под патентной защитой. Поставщики таких препаратов подпадают под действие Добровольной или Принудительной схемы доступа на рынок и обязаны осуществлять платежи в виде фиксированного процента продаж в пользу Департамента здравоохранения и социального обеспечения. Отдельные сегменты лекарств освобождены от платежей с целью стимулирования инновационного развития фармацевтической отрасли и ускорения доступа на рынок новых видов терапии. Как показывает практика, Добровольная схема выгоднее для большинства компаний. Регулирование в сегменте воспроизведенных ЛП осуществляется механизмами свободного рынка и антимонопольной службой.Заключение. В результате анализа выявлены механизмы и ключевые особенности методов государственного регулирования цен и издержек системы здравоохранения на закупку ЛП, определены лучшие практики, перспективные для адаптации с целью совершенствования подходов государственного регулирования цен в Российской Федерации
Обзор методик расчета, процедуры регистрации и перерегистрации цен производителей лекарственных препаратов в странах Евразийского экономического союза
Aim. To analyze the methods of the state regulation of prices for the manufacturers of pharmaceutical drugs in the Eurasian Economic Community counties (EAEC).Materials and Methods. The comparison of the aspects of the price regulation was presented as short characteristics of the regulating impact of the key normative legal acts (NLA) in the sphere of price formation on pharmaceutical drugs in the EAEC. The study included the following stages: the analysis of NLA in the Russian Federation, Republic of Belarus, Republic of Kazakhstan, Republic of Moldova, Republic of Armenia, and the Kyrgyz Republic, the comparison of the list of reference countries, and decreasing coefficients.Results. The authors revealed the differences in the procedure of the registration, re-registration, referencing of prices, and decreasing coefficients for the generics. The authors highlighted the drawbacks of the existing procedure of the registration of prices in Russia in terms of the formation of the list of the referent countries, the re-registration of drugs with an increase in price, and limited economic efficiency.Conclusion. The performed analysis showed that the differences in the methods of the state regulation of prices on pharmaceutical drugs in the EAEC countries do not allow for the formation of a unified approach. However, the creation of supranational method of price formation is an essential condition for the functioning of the united market of pharmaceutical drugs.Цель. Анализ методов государственного регулирования цен производителей лекарственных препаратов в странах-участницах Евразийского экономического союза (далее – ЕАЭС, Союз).Материалы и методы. Сопоставление аспектов ценового регулирования представлено в виде краткой характеристики регулирующего воздействия ключевых статей нормативных правовых актов (далее – НПА) в сфере ценообразования на лекарственные препараты в странах ЕАЭС. Исследование включало следующие этапы: анализ НПА в Российской Федерации, Республике Беларусь, Республике Казахстан, Республике Молдова, Республике Армения, Киргизской Республике; сравнение перечня референтных стран, понижающих коэффициентов.Результаты. Выявлены различия в процедурах регистрации, перерегистрации, реферирования цен, величине понижающих коэффициентов для воспроизведенных препаратов, выделены недостатки существующего порядка регистрации цен в России в части формирования перечня референтных стран, перерегистрации цены производителя в сторону увеличения, ограничения рентабельности.Заключение. По результатам анализа сделан вывод о том, что различия в методах государственного регулирования цен на лекарственные препараты в странах ЕАЭС на данный момент не позволяют сформировать универсальный подход, однако создание наднациональной методики ценообразования является необходимым условием для функционирования единого рынка лекарственных средств
Is concern about young people's anti-social behaviour associated with poor health? cross-sectional evidence from residents of deprived urban neighbourhoods
<p><b>Background:</b> Young people in disadvantaged neighbourhoods are often the focus of concerns about anti-social behaviour (ASB). There is inconsistent evidence to support the hypothesis that perceptions of ASB (PASB) are associated with poor health. We ask whether perceptions of young people's ASB are associated with poor health; and whether health, demographic and (psycho)social characteristics can help explain why PASB varies within disadvantaged neighbourhoods (Glasgow, UK).</p>
<p><b>Methods:</b> Regression analysis of survey data exploring associations between perceiving teenagers hanging around to be a serious neighbourhood problem and SF-12v2 mental and physical health scores (higher = better), including adjustment for demographic characteristics. Further analysis explored associations with self-reported measures of health service use, psychosocial characteristics of homes and neighbourhoods and social contacts.</p>
<p><b>Results:</b> 6008 adults participated (50% response) and 22% (n = 1,332) said teenagers were a serious neighbourhood problem (the most frequently reported local problem). Demographic characteristics associated with perceiving serious teenager problems included regular health service use, age (inverse relationship), financial problems and living with children. Lower SF-12v2 physical health scores were associated with perceiving teenager problems after adjustment for demographic variables (OR 0.98; 95%CI 0.97,0.99; p = < 0.001), whilst adjusted findings for mental health scores were less conclusive (OR 0.99; 95%CI 0.98,1.00; p = 0.103). Further analysis suggested that perceiving teenager problems was more strongly associated with a number of self-reported psychosocial factors: e.g. lacking social support, < weekly family contacts, poor neighbourhood safety, low trust in neighbours, neighbourhood perceived to be a barrier to self-esteem, and neighbourhood decline.</p>
<p><b>Conclusions:</b> Given the evidence we found of weak and small associations between PASB and health, we caution against assuming that tackling concern about teenagers' ASB will lead to substantial public health gains in disadvantaged areas. Although the findings do not present a compelling case for making PASB a public health priority, it is still important to address concerns about young people's ASB. Reasons for doing so may include improving social cohesion, reducing fear and isolation, and improving the general quality of people's lives - particularly in neighbourhoods burdened by multiple disadvantages. Future research should evaluate interventions that attempt to reduce PASB in disadvantaged areas. Findings from this study could help inform the targeting of such interventions.</p>
Bridging the gap between global models and full fluid models : a fast 1D semi-analytical fluid model for electronegative plasmas
Analytical and numerical models allow investigation of complicated discharge phenomena and the interplay that makes plasmas such a complex environment. Global models are quick to implement and can have almost negligible computation cost, but provide only bulk or spatially averaged values. Full fluid models take longer to develop, and can take days to solve, but provide accurate spatio-temporal profiles of the whole plasma. The work presented here details a different type of model, analytically similar to fluid models, but computationally closer to a global model, and able to give spatially resolved solutions for the challenging environment of electronegative plasmas. Included are non-isothermal electrons, gas heating, and coupled neutral dynamics. Solutions are reached in seconds to minutes, and spatial profiles are given for densities, fluxes, and temperatures. This allows the semi-analytical model to fill the gap that exists between global and full fluid models, extending the tools available to researchers. The semi-analytical model can perform broad parameter sweeps that are not practical with more computationally expensive models, as well as exposing non-trivial trends that global models cannot capture. Examples are given for a low pressure oxygen CCP. Excellent agreement is shown with a full fluid model, and comparisons are drawn with the corresponding global model

Values - reviewing the construct and drawing implications for values work in organisation and leadership. Kap. 2
I: H.Askeland, G. Espedal, B. Jelstad Løvaas & S. Sirris (Eds.), Understanding values work : Institutional perspectives in organizations and leadershipThis chapter outlines the trajectory of values, particularly within streams of organisational institutionalism, in order to analyse its application to values work in organisation and leadership. Conveying a frame for discussing values work, it aims at clarifying how to conceptualise the term values. Discussing classic and recent contributions, the chapter proposes seeing values as individual and collective conceptions of desirable trans-situational behaviours, objectives and ideals, serving to guide or valuate practice. Despite being an essential part of defining organisational institutionalism, and its sub-streams, values are seldom explicated. Utilising values in organisational and leadership research requires attention to their situatedness in contexts, and this chapter argues they are salient to organisations operating in pluralistic institutional environment. Studying values work, attention should be given to who and how such work is performed.publishedVersio
