AbstractDiglycolamide (DGA) resin, a product produced by Eichrom Technologies, Inc. employs TODGA (N,N,N′,N′-tetraoctyldiglycolamide) as the active extractant, which will be used by Savannah River National Laboratory to extract trivalent actinides and lanthanides from dissolved irradiated Mark-18A targets. The final form of the extracted material will be an oxide suitable for shipment. A two-step process was developed and validated for the direct recovery of actinides and lanthanides loaded on I-grade DGA resin as nitrates by thermally drying and decomposing resin loaded with Nd(III), a surrogate for trivalent actinides and lanthanides, under inert conditions followed by calcining the resultant residue in air to provide an oxide product. A stepwise heating profile up to 385°C under argon gas flow resulted in 85% to 89% mass loss during the resin drying and decomposition step, and calcination of the resultant Nd-loaded resin residue provided an overall material mass loss of ≥ 98%. Recoveries from resin saturated with Nd(III) from 7 M and 0.35 M nitric acid subjected to this process were 30.7 mg and 27.6 mg Nd/g dry resin, respectively, representing an average of 96.1% of Nd retained in the resin bed.

Our cost of illness study aimed to provide an estimate of the burden related to systemic lupus erythematosus (SLE) in the Mexican context. Our model was used to simulate the resource utilization and economic consequences over a period of 5 years for patients with SLE in Mexico. The model simulated four health states—three phenotypes of SLE, including mild, moderate, and severe states, and death. Clinical parameters were retrieved from the literature. Resource utilization in our model represents the most common practice in the Mexican healthcare system. These include disease management, transient events (e.g. infections, flares, and complications due to SLE-related organ damage), and indirect costs. Direct non-medical costs were not considered. One-way sensitivity analysis was performed. The number of targeted Mexican SLE patients was 57,754. The numbers of SLE patients diagnosed with mild, moderate, and severe phenotypes were 8,230, 44,291, and 5,233, respectively. Disease management costs, including the treatment of each phenotype and disease follow-up, were MXN 4 billion ($ 415 million); the costs of transient events (infections, flares, and consequences of SLE-related organ damage) were MXN 5 billion ($ 478 million). Productivity loss costs among adult employed Mexican patients with SLE were estimated at MXN 17 billion ($ 1.6 billion). The total SLE cost in Mexico over 5 years from the payer and societal perspectives is estimated at MXN 9 billion ($ 893 million) and 26 billion ($ 2.5 billion), respectively. Over 5 years, the costs per patient per year from the payer and societal perspectives were MXN 32,131($ 3,095) and MXN 91,661($ 8,830), respectively. The findings pointed out the substantial economic burden associated with SLE, including the costs of disease progression and SLE transient events, such as flare-ups, infections, and organ damage, in addition to productivity loss due to work capacity impairment.

Our study aims to provide an enhanced comprehension of systemic lupus erythematosus (SLE) burden in United Arab Emirates (UAE), over a five-year period from payer and societal perspective. A Markov model was established to simulate the economic consequences of SLE among UAE population. It included four health states: i) the three phenotypes of SLE, representing mild, moderate, and severe states, and ii) death. Clinical parameters were retrieved from previous literature and validated using the Delphi panel—the most common clinical practice within the Emirati healthcare system. We calculated the disease management, transient events, and indirect costs by macro costing. One-way sensitivity analysis was conducted. The estimated number of SLE patients in our study was 13,359. The number of SLE patients with mild, moderate, and severe phenotypes was 3,914, 8,109, and 1,336, respectively. Disease management costs, including treatment of each phenotype and disease follow-up, were AED 2 billion ($0.89 billion), whereas the costs of transient events (infections, flares, and consequences of SLE-related organ damage) were AED 1 billion ($0.44 billion). The productivity loss costs among adult-employed patients with SLE in the UAE were estimated at AED 7 billion ($3.1 billion). The total SLE cost over five years from payer and societal perspectives is estimated at AED 3 ($1.3 billion) and 10 billion ($4.4 billion), respectively. Additionally, the costs per patient per year from the payer and societal perspectives were AED 45,960 ($20,610) and AED 148,468 ($66,578), respectively. Our findings demonstrate that the burden of SLE in the UAE is enormous, mainly because of the costly complications and productivity loss. More awareness should be created to limit the progression of SLE and reduce the occurrence of flares, necessitating further economic evaluations of novel treatments that could help reduce the economic consequences of SLE in the UAE.

SLE imposes a significant morbidity and mortality as well as a substantial burden on the healthcare system. The model aimed to measure the cost-effectiveness of anifrolumab implementation against belimumab as an add-on-therapy to the standard of care (SoC) over a lifetime horizon for Emirati patients. A microsimulation model was used to assess the cost-effectiveness of anifrolumab against belimumab (IV/SC) as an add-on therapy to SoC in a hypothetical cohort of adult Emirati patients with systemic lupus erythematosus (SLE) over a lifetime horizon. The clinical data was captured from published clinical trials as; TULIP-1, TULIP-2, BLISS-52, BLISS-76 and BLISS‐SC. Health utility scores were constructed according to a linear regression model from the pooled data of the two TULIP Phase III trials of anifrolumab. Our model captures direct SLE-related medical costs from the Dubai Health Authority. Sensitivity analyses were conducted to assess model uncertainty. Using BICLA as a response criterion in the Johns Hopkins cohort, anifrolumab was found to be more effective than belimumab (IV/SC; the incremental discounted QALY of anifrolumab against belimumab was 0.42). The incremental cost-effectiveness ratio (ICER) of anifrolumab against belimumab IV and belimumab SC were AED 466,371 ($209,135) and AED 252,612 ($113,279), respectively, these ICERs are below the cost-effectiveness threshold in the United Arab Emirates (UAE) (three times gross domestic product capita; AED 592,278). In the Toronto lupus cohort, the ICER of anifrolumab against belimumab IV and belimumab SC were AED 491,403 ($220,360) and AED 276,642 ($124,055), respectively (anifrolumab was a cost-effective option vs. belimumab IV and belimumab SC). The addition of anifrolumab to SoC is a cost-effective option versus belimumab for the treatment of adult patients with active, autoantibody-positive SLE, despite being allocated to SoC. Cost-effectiveness was demonstrated by a reduction in complications and organ damage, which reflected costs and outcomes. [ABSTRACT FROM AUTHOR]

Our cost-of-illness (COI) model adopted both payer and societal perspectives over a time horizon of 5 years to measure the economic burden of systemic lupus erythematosus (SLE) in Taiwan. A prevalence-based model was established to estimate the economic consequences of SLE after diagnosis in Taiwan. The model included four health states: (i) the three phenotypes representing mild, moderate, and severe SLE, and (ii) death. The inputs were obtained from a literature review of all the clinical trials and validated using a Delphi panel. The Delphi panel's insights included commonly used treatment strategies for patients with SLE within the Taiwanese healthcare system. The costs mentioned in this model are disease management, monitoring, transient event, and indirect costs. One-way sensitivity analyses were conducted to assess the model uncertainty. The number of patients with SLE in our COI model was 20,189. At diagnosis, the number of SLE patients with mild, moderate, and severe phenotypes was 5,916, 12,255, and 2019, respectively. The total SLE cost in Taiwan over 5 years from both payer and societal perspectives was estimated at TWD 3.9 and 47 billion, respectively. The costs per patient per year from the payer and societal perspective were TWD 38,775 ($2,758) and TWD 466,119 ($33,152), respectively. The findings demonstrated that the burden of SLE in Taiwan over a time horizon of 5 years is substantially high, mainly due to the consequences of economic loss as it affects women and men during their working age, in addition to the costs of SLE management and its consequences, such as flares, infection, and organ damage. Therefore, more attention should be paid to limiting the progression of SLE and the occurrence of flares, and further economic evaluations are necessary to assess novel treatment strategies that could control the disease.

Our cost-of-illness (COI) model adopted the perspective of both payer and society over a time horizon of 5 years to measure the economic burden of systemic lupus erythematosus (SLE) in Malaysia. Our COI model utilized a prevalence-based model to estimate the costs and economic consequences of SLE in Malaysia. The clinical parameters were obtained from published literature and validated using the Delphi panel. Direct and indirect medical costs were measured, including disease management, transient events, and indirect costs. One-way sensitivity analysis was also performed. The number of target Malaysian patients with SLE in the COI model was 18,121. At diagnosis, the numbers of SLE patients with mild, moderate, and severe phenotypes were 2,582, 13,897, and 1,642, respectively. The total SLE cost in Malaysia over 5 years from both payer and society perspectives was estimated at MYR 678 million and 2 billion, respectively. The results showed a considerable cost burden due to productivity losses resulting from SLE-related morbidity and mortality. Over a 5-year time horizon, the costs per patient per year from the payer and society perspectives were MYR 7,484 ($4766) and 24,281($15,465), respectively. Our study demonstrated the substantial economic burden of SLE in Malaysia over a time horizon of 5 years. It affects adults of working age, in addition to the costs of SLE management and its consequences, such as flares, infection, and organ damage. Our COI model indicated that disease management costs among patients with higher disease severity were higher than those among patients with a mild phenotype. Hence, more attetion should be paid to limiting the progression of SLE and the occurrence of flares, with the need for further economic evaluation of novel treatments that could lead to better outcomes.

Our cost-of-illness (COI) model adopted payer and societal perspectives over five years to measure the economic burden of Systemic Lupus Erythematosus (SLE) in Colombia. A prevalence-based model was constructed to estimate costs and economic consequences for SLE patients in Colombia. The model included four health states: three phenotypes of SLE representing mild, moderate, and severe states and death. The clinical inputs were captured from the published literature and validated by the Delphi panel. Our model measured direct medical and indirect costs, including disease management, transient events, and indirect costs. One-way sensitivity analysis was also performed. The number of Colombian SLE patients was 37,498. The number of SLE patients with mild, moderate, and severe phenotypes was 5343, 28757 and 3,397, respectively. SLE-patients with moderate (Colombian pesos; COP 146 billion) and severe phenotypes (COP276 billion) incurred higher costs than those with mild phenotypes (COP2 billion), over 5 years. The total SLE cost in Colombia over five years from the payer and societal perspectives was estimated to be COP 915 billion and 8 trillion, respectively. The costs per patient per year from the payer and societal perspectives were COP 4,881,902 ($3,510) and COP 46,637,054 ($33,528), respectively. The burden of SLE in Colombia over five years is substantially high, mainly due to the consequences of economic loss because it affects women and men of working age, in addition to the costs of SLE management and its consequences, such as flares, infection, and organ damage. Our COI indicated that disease management costs among patients with moderate and severe SLE were substantially higher than those among patients with a mild phenotype. Therefore, more attention should be paid to limiting the progression of SLE and the occurrence of flares, with the need for further economic evaluation of novel treatment strategies that help in disease control.

Due to the rapid growth of the global economy, energy consumption has been steadily increasing, leading to increasing issues such as energy shortages and environmental concerns. Biomass energy, a critical renewable energy source, plays a vital role in advancing low-carbon energy development and resource sustainability. In this study, experiments were conducted to study the migration of C, H, and N elements of corn straw during the microwave heating process, and the effects of residence time, heating temperature, and microwave power were also investigated. The results showed that when the temperature rose, both the proportion of C and H elements fluctuated slightly. Specifically, when the temperature rose from 75 °C to 275 °C, there was a 1.02% increase in the proportion of the C element and a 0.25% decrease in the proportion of the H element. Residence time appeared to be a significant factor influencing the changes in C, H, and N elements. For a 40 min residence time, the proportion of the C element increased from 31.77% to 35.36%, while the proportion of the H element decreased from 4.50% to 3.83%. When there was an increase in the microwave power between 160 W and 200 W, higher temperatures were reached in the samples, leading to the carbonization process of corn straw being more complete. Consequently, the proportion of the C element rose with extended residence time, whereas the proportion of the H element decreased as the residence time increased. [ABSTRACT FROM AUTHOR]

Proposed Ti15.4Zr30.2Mn(54.4−x−y)VxNiyCry alloy compositions are characterized by improved characteristics, in particular hydrogen saturation at room temperature and relatively low pressure, which makes them promising for using in hydrogen energy. It established that only part of the nickel introduced into the alloy dissolves in the Laves phase (type C14) and as a result, its phase composition and microstructure change. It was determined that the change in the phase composition of the alloy does not affect the kinetics of the hydrogen absorption process, but leads to a change hydrogen capacity and increase in the temperature at which all hydrogen release.

This study examines the interplay between tax haven use, geographic disclosures and corporate tax avoidance. Based on a panel of 497 non-financial EU listed firms during the period 2006–2012, we provide evidence that corporate groups with affiliates in tax havens tend to have lower effective tax rates and lower geographic disclosures fineness scores. We, also, find a positive association between geographic disclosures fineness scores and the firms' effective tax rates. We, further, find that the negative association between tax haven use and the effective tax rate is more pronounced for firms disclosing geographic information at a more aggregated level, showing a moderating effect of geographic disclosures fineness on such association. Our findings are based upon hand-collected data on corporate geographical dispersion, and corroborated by several additional and robustness tests. The research results should be of concern to policymakers and others interested in multinational companies' segment reporting practices and tax planning activities. [ABSTRACT FROM AUTHOR]

The influence of quantum plasma on Jeans instability is investigated in the presence of magnetic fields, and the dispersion relation obtained in both parallel and perpendicular directions has shown the stabilizing effect on the growth rate of Jeans instability with a moderate temperature high-density regime. The influence of the magnetic field on the Jeans criteria is illustrated through the graphical representation. The inclusion of magnetic fields with quantum effect on the motion of a charged particle involves the essential properties of acceleration and the transport of highly ionized particles is important in connection with a well-known application of the confinement of magnetized plasma. In this paper, we analytically discuss the effect of magnetic field on white dwarfs. The mass-radius relation of highly magnetized white dwarfs is different from their non-magnetic equivalent and leads to a modified super-Chandrashekhar mass limit. [ABSTRACT FROM AUTHOR]

Public debt can be reduced in three ways: (1) repayment; (2) default; and (3) indirect default through monetary financing accompanied by debasement or followed by currency reform. In the course of history, repayment was more the exception than the rule, default often the only available way when a government had no control over the currency in which it borrowed, and indirect default more the rule than the exception. In this paper we review the three ways of debt reduction with exemplary references to historical events. We conclude that financial repression supplemented with debt repayment is likely to be the preferred way for public debt reduction today. The alternative would be currency reform.

Hydrophobic organic contaminated polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs) and CHNS (carbon, hydrogen, nitrogen and sulphur species) are explosively associated with road dust particles. A few organic contaminants are toxic in nature and have an unpleasant effect on human health. The International Agency for Research on Cancer (IARC), the US Department of Health and Human Services (HHS) and the United States–Environmental Protection Agency has considered several PAHs and PCBs as carcinogens for human beings. In the proposed study, the anthropogenic contaminants present in road dust were assessed in six representative diversified sites i.e. industrial, commercial, office, residential, construction and traffic intersection in Delhi NCR, India. Roadside dust samples were gathered in premonsoon, monsoon and postmonsoon seasons and characterized for PAHs, PCBs and CHNS. The concentration of total PAHs (16 Nos) and PCBs (6 Nos) of the selected sites ranged from 0.27 µg/kg to 605.80 µg/kg and 0.01 µg/kg to 41.26 µg/kg, respectively. The Fourier transform infrared spectroscopy-attenuated total reflectance study suggested that the presence of O = C = O, Si–O, carbonyl, acidic or aliphatic esters group were associated with road dust particles. Hydrogen and sulphur concentrations were not detected in the selected road dust samples. Carbon and nitrogen concentrations varied from 2.24% to 16.82% and 0.69% to 14.5%, respectively, seasonally. In the premonsoon season, road dust was distinguishably contaminated as compared to monsoon and postmonsoon season, which might be due to movement of contaminated road dust from adjacent locations. It was perceived that Delhi NCR organic contamination in road dust was much below as compared to other countries. It may be concluded that due to the presence of significant amounts of carbon and nitrogen concentrations in the road dust, to a greater extent, road dust can be fertile and might be advantageous for green belt development to mitigate air pollution. The utilization of road dust will further bring down the burden of landfill sites and may lead towards sustainability. [ABSTRACT FROM AUTHOR]

BK virus associated hemorrhagic cystitis(BKV-AHC) is a serious complication observed after allogeneic stem cell transplantation and the current therapeutic options are scarce with substantial renal side effects. Although the guidelines recommend intravenous cidofovir application with caution to nephrotoxicity, there are few studies which investigated intravesical administration and reported similar therapeutic results with less renal side effects. Methods: We administered low dose, daily and consecutive (75 mg/day, for 5 days) intravesical cidofovir to 25 patients with BKV-AHC that developed after (ASCT). Results: The response rate in our cohort was 92% and relapse was not encountered in 84% of the patient population during one year of follow-up. The median BK urine viral load significantly decreased from 260,000,000 IU/mL to 53,000,000 IU/mL after a week of treatment (p = 0.0001). Rise in serum creatinine was observed in 5 patients during treatment and post-treatment nephrotoxicity was seen in only 1 patient. Conclusions: Daily low dose intravesical cidofovir might be an effective treatment option for BKV-AHC after ASCT with favorable less systemic side effects. [ABSTRACT FROM AUTHOR]

The War of the Worlds is a famous novel by British writer H.G. Wells. Having been serialised in 1897 in Pearson's Magazine in the UK and in Cosmopolitan in the USA, it is also an early example of globalisation, as it was read simultaneously on both sides of the Atlantic. Furthermore, unlike other works of the time (especially American) which conjured up social paradises and utopian worlds on planet Mars, Wells' novel introduced into Western imagery the concretisation of a real threat coming from other worlds and capable of destroying the 'civilisation' that Europe and America had painstakingly built. The narrator, sometimes assuming the traits of the voyeur, and at other times those of the flaneur, becomes the symbol of a crepuscular phase of Western society that is already on its way towards the condition of a wasteland. Thanks to a deus-ex-machina device consisting in a new and powerful, albeit elementary, coalition between God and biology, the narrator survives the end of beauty, not only in an aesthetic sense, but also as a cultural heritage that should be preserved. As such, he is one of the most interesting and controversial characters of dystopian fiction; and it is not by chance that the novel has had so many sequels, accompanied by pastiches and adaptations, which have turned it into a real cult work transcending time and space. I intend to focus both on the characteristics of the narrator as a transmedia character and on the American reception of the original novel in the phase of transition from the Gay Nineties to the Progressive Era. This is a little investigated subject if compared, for example, to the countless studies on the collective panic that followed Orson Welles' radio play in 1938. [ABSTRACT FROM AUTHOR]

To assess the potential clinical impact and cost-effectiveness of COVID-19 mRNA vaccines updated for fall 2023 in adults aged ≥18 years over a 1-year analytic time horizon (September 2023-August 2024). A compartmental Susceptible-Exposed-Infected-Recovered model was updated to reflect COVID-19 cases in summer 2023. The numbers of symptomatic infections, COVID-19–related hospitalizations and deaths, and costs and quality-adjusted life-years (QALYs) gained were calculated using a decision tree model. The incremental cost-effectiveness ratio (ICER) of a Moderna updated mRNA fall 2023 vaccine (Moderna Fall Campaign) was compared to no additional vaccination. Potential differences between the Moderna and the Pfizer-BioNTech fall 2023 vaccines were also examined. Base case results suggest that the Moderna Fall Campaign would decrease the expected 64.2 million symptomatic infections by 7.2 million (11%) to 57.0 million. COVID-19–related hospitalizations and deaths are expected to decline by 343,000 (-29%) and 50,500 (-33%), respectively. The Moderna Fall Campaign would increase QALYs by 740,880 and healthcare costs by $5.7 billion relative to no vaccine, yielding an ICER of $7700 per QALY gained. Using a societal cost perspective, the ICER is $2100. Sensitivity analyses suggest that vaccine effectiveness, COVID-19 incidence, hospitalization rates, and costs drive cost-effectiveness. With a relative vaccine effectiveness of 5.1% for infection and 9.8% for hospitalization for the Moderna vaccine versus the Pfizer-BioNTech vaccine, use of the Moderna vaccine is expected to prevent 24,000 more hospitalizations and 3300 more deaths than the Pfizer-BioNTech vaccine. As COVID-19 becomes endemic, future incidence, including patterns of infection, are highly uncertain. The effectiveness of fall 2023 vaccines is unknown, and it is unclear when a new variant that evades natural or vaccine immunity will emerge. Despite these limitations, our model predicts the Moderna Fall Campaign vaccine is highly cost-effective across all sensitivity analyses. [ABSTRACT FROM AUTHOR]

To assess, within the Italian healthcare system, the cost-effectiveness of baricitinib versus dupilumab, both in combination with topical corticosteroids (TCS), in adults with moderate to severe atopic dermatitis (AD) who are eligible for but have failed, have contraindications to, or cannot tolerate ciclosporin. Using the perspective of the Italian healthcare payer, direct medical costs associated with each intervention were estimated over a lifetime horizon. A Markov cohort model utilized the proportions of patients with ≥75% improvement Eczema Area and Severity Index obtained from clinical trials. Health outcomes were evaluated in quality-adjusted life years (QALYs) to assess the cost effectiveness of baricitinib against a willingness-to-pay threshold of €35,000 per QALY gained. In the base case, with secondary censoring applied, patients treated with dupilumab or baricitinib, in combination with TCS, accumulated total costs of €135,780 or €129,586, and total QALYs of 18.172 or 18.133, respectively. The incremental cost-effectiveness ratio of dupilumab versus baricitinib was estimated at €160,905/QALY. Core assumptions were needed to extrapolate available short-term clinical trial data to lifelong data, adding uncertainty. Benefits of baricitinib seen in clinical trials and not assessed in dupilumab clinical trials were not included. Discontinuation rates for each treatment were derived from different sources potentially introducing bias. Results may not be generalizable to other populations. This cost-effectiveness analysis shows that, from the Italian healthcare payer perspective, in the treatment of patients with moderate to severe AD who have experienced failure on, are intolerant to, or have contraindication to ciclosporin, dupilumab cannot be considered cost-effective when compared with baricitinib. Given its oral administration, favorable risk/benefit profile and lower acquisition cost compared with dupilumab, baricitinib may offer a valuable, cost-effective treatment option—after failure on conventional systemic agents—for patients with moderate to severe AD in Italy. Baricitinib is the first oral systemic treatment for patients with moderate to severe atopic dermatitis (AD). The drug was effective for treating patients with AD in clinical trials, producing improvements in skin inflammation, itch, sleep disturbances due to itch and skin pain, as well as the quality of life of patients. However, it is important to ensure that healthcare funds are well spent. We therefore compared the cost-effectiveness of baricitinib, with another new systemic treatment for AD, dupilumab, (both in combination with topical corticosteroids) in patients with moderate to severe AD who are eligible for but have failed or are unable to take ciclosporin, in Italy. We found that using dupilumab to treat these patients with AD cost more than using baricitinib, although dupilumab was more effective. Combining these considerations showed that the cost of obtaining the additional benefit from dupilumab over baricitinib was not cost-effective for the Italian healthcare system. Baricitinib may be a better treatment option because it is given orally, has a favorable balance between the risks and benefits of treatment, and costs less than dupilumab. [ABSTRACT FROM AUTHOR]

As innovative oncology medicines are rapidly developed, there is increasing pressure on payers to offer patients timely access to life-saving therapies. The uncertainty surrounding these therapies when phase III clinical trials are pending has necessitated new, adapted pathways to market access, with timelines that greatly vary by country. Understanding differences between pathways may identify opportunities to expedite patient access universally. To describe early access pathways for new oncology medicines among selected countries with established health technology assessment (HTA) frameworks and publicly funded health systems, with a special focus on real-world evidence (RWE). We reviewed the HTA agency websites of the selected OECD countries: National Institute for Health and Care Excellence (NICE) for England and Wales; Haute Autorité de Santé (HAS) for France; IQWiG and G-BA for Germany; Agenzia Italiana del Farmaco (AIFA) for Italy; Pharmaceutical Benefits Advisory Committee (PBAC) for Australia; and CADTH and Institut National d'Excellence en Santé et Services Sociaux (INESSS) for Canada as the primary source of evidence. Processes for early patient access to innovative oncology therapies varied across selected countries; however, most countries have an established pathway for publicly funded early access (England and Wales, France, Germany, Italy, and Australia). The utilization of RWE to support earlier access (coverage with evidence) also varied by country, with some HTA organizations being actively engaged in these agreements (NICE, AIFA, and HAS) and others having no established processes in place (G-BA and CADTH/INESSS). This review of early access pathways for novel oncology medicines found substantial variability between countries of interest. Coverage with evidence frameworks may provide a unique opportunity for industry and payers to collaborate on earlier access to innovative cancer therapies with life-saving potential.

To describe clinical complications, treatment use, healthcare resource utilization (HCRU), and costs among patients with transfusion-dependent β-thalassemia (TDT) in the United States. Merative MarketScan Databases were used to identify patients with β-thalassemia between 1 March 2010, and 1 March 2019. Patients were eligible for inclusion with ≥1 inpatient claim or ≥2 outpatient claims for β-thalassemia and ≥8 red blood cell transfusions (RBCTs) during any 12-month period after and including the date of the first qualifying β-thalassemia diagnosis code. Matched controls consisted of individuals without β-thalassemia. Clinical and economic outcomes of patients were assessed during ≥12 months of follow-up, defined as the period from the index date (i.e. the first RBCT) to either the end of continuous enrollment in benefits, inpatient death, or 1 March 2020. Overall, 207 patients with TDT and 1035 matched controls were identified. Most patients received iron chelation therapy (ICT) (91.3%), with a mean of 12.1 (standard deviation [SD] = 10.3) ICT claims per-patient-per-year (PPPY). Many also received RBCTs, with a mean of 14.2 (SD = 4.7) RBCTs PPPY. TDT was associated with higher annual ($137,125) and lifetime ($7.1 million) healthcare costs vs. matched controls ($4183 and $235,000, respectively). Annual costs were driven by ICT (52.1%) and RBCT use (23.6%). Patients with TDT had 7-times more total outpatient visits/encounters, 3-times more prescriptions, and 33-times higher total annual costs than matched controls. This analysis may underestimate the burden of TDT, as indirect healthcare costs (e.g. absenteeism, presenteeism, etc.) were not included. Results may not be generalizable to patients excluded from this analysis, including those with other types of insurance or without insurance. Patients with TDT have high HCRU and direct healthcare costs. Treatments that eliminate the need for RBCTs could reduce the clinical and economic burden of managing TDT. [ABSTRACT FROM AUTHOR]

Paediatric growth hormone deficiency (pGHD) manifests as growth failure associated with inadequate growth hormone (GH) production. Daily injections of recombinant human GH (dGH) [somatropin] is the current standard of care, which has been shown to be well tolerated and effective, but associated with suboptimal adherence, leading to reduced effectiveness. Somatrogon, a once-weekly injectable long-acting human GH, has demonstrated clinical non-inferiority and significantly lower life interference (i.e. treatment burden) vs. somatropin in two Phase 3 studies. This work evaluated cost-effectiveness and cost-utility of somatrogon vs dGHs from an Irish payer perspective. A Markov model was developed for patients starting somatrogon or dGHs treatment at 3–12 years and continuing up to achievement of near adult height (NAH), with growth driven by trial-based height velocity (HV) and treatment-specific adherence. Patients could discontinue treatment at the end of Year 1 (4%). DGH adherence (95.3%–65% over treatment duration) and adherence-growth relationship were based on published evidence. Higher Year 1 adherence of 4%, tapering over time, for somatrogon vs. dGHs was based on clinical consultation. Treatment costs, monitoring costs and costs due to different wastage types (device setting and adherence) were sourced from local data. Health utilities based on height and injection frequency were derived from published literature. Scenario analysis, deterministic and probabilistic sensitivity analysis were performed. Somatrogon treatment led to 1.87–3.66 cm greater NAH gain and 0.21–0.50 higher quality adjusted life years (QALYs) vs. dGHs, across the base case and scenarios evaluated. Somatrogon treatment was associated with cost savings of €5,699–€21,974 and lower cost per cm gained vs. dGHs (€197–€527), per patient. Somatrogon was cost-effective vs. dGHs, with the result consistent across the sensitivity analyses conducted. Somatrogon weekly injections were estimated to result in higher NAH, higher QALYs, lower overall costs and lower costs per cm gained than dGHs, in pGHD. [ABSTRACT FROM AUTHOR]

To determine the cost of wound care and prevalence of chronic wounds for Medicare beneficiaries in the aggregate, by wound type, and by setting between the years 2014 and 2019. This retrospective analysis of Medicare claims data included beneficiaries who experienced episodes of care for diabetic foot ulcers and infections; arterial ulcers; skin disorders and infections; surgical wounds and infections; traumatic wounds; venous ulcers and infections; unspecified chronic ulcers; and others. The 2014 data were based on a Medicare 5% Limited Data Set whereas for 2019 the data used were for all fee-for-service Medicare beneficiaries. Three methods were used to generate expenditure estimates: (a) a low (Medicare provider payments when the wound was a primary diagnosis, excluding any kind of deductible); (b) mid (primary plus secondary diagnosis with weighted attribution); and (c) high (primary or secondary diagnosis). The main outcomes were the prevalence of each wound type, Medicare expenditure for each wound type and aggregate, and expenditure by type of service. Over the 5-year period the number of Medicare beneficiaries with a wound increased from 8.2 million to 10.5 million. Wound prevalence increased by 13% from 14.5% to 16.4%. Over the 5-year period, the Medicare beneficiaries with the largest increase in chronic wound prevalence were those aged <65 years (males: 12.5% to 16.3%; females: 13.4% to 17.5%). The largest changes in terms of wound prevalence were increases in arterial ulcers (0.4% to 0.8%), skin disorders (2.6% to 5.3%), and decreases in traumatic wounds (2.7% to 1.6%). Expenditures decreased regardless of the three methods used with a reduction of $29.7 billion to $22.5 billion for the most conservative method. Except for venous ulcers in which costs per Medicare beneficiary increased from $1206 to $1803, cost per wound decreased with surgical wounds remaining the most expensive to treat (2014: $3566; 2019: $2504), and the largest decrease for arterial ulcers ($9651 to $1322). Hospital outpatient fees saw the largest reduction ($10.5 billion to $2.5 billion) although home health agency expenditures decreased from $1.6 billion to $1.1 billion. Physician offices saw an increase from $3.0 billion to $4.1 billion and durable medical equipment increased from $0.3 billion to $0.7 billion. It appears that chronic wound care expenditures have shifted to the physician's office from the hospital-based outpatient department. Given that the prevalence of chronic wounds is increasing, especially among the disabled under 65, it will be important to know whether these shifts have positively or negatively affected outcomes. In 2014 chronic wounds impacted 14.5% of Medicare beneficiaries but this increased to 16.3% by 2019. The group of Medicare beneficiaries most affected in terms of chronic wound prevalence over the 5-year period were those aged <65 years (males: 12.5% to 16.3%; females: 13.4% to 17.5%). The largest changes in terms of prevalence were increases in arterial ulcers (0.4% to 0.8%), skin disorders (2.6% to 5.3%), and traumatic wounds (2.7% to 1.6%) Over the 5-year period, regardless of the method used, there was a decrease in chronic wound-related costs ($29.7 billion in 2014 to $22.5 billion in 2019 for the most conservative method: Medicare provider payments when the wound was a primary diagnosis, excluding any kind of deductible). Surgical complications still represent the largest wound category of costs with a small decrease from 2014 to 2019 of $6.1 billion to $5.9 billion. Based on the most conservative method, there was a very large cost reduction observed for outpatients from $10.5 billion to $2.5 billion with a correspondingly smaller decrease for inpatients of $5.3 billion to $4.2 billion, but an increase from $3.0 billion to $4.1 billion for physician offices. In addition, while durable medical equipment increased from $0.3 billion to $0.7 billion, home health agency expenditures decreased from $1.6 billion to $1.1 billion. Our data suggest that while most of the cost remains in the subacute setting it has shifted to the physician's office from the hospital-based outpatient department. Given the increasing prevalence of chronic wounds, especially among the disabled under 65, it will be important to know whether these shifts have positively or negatively affected outcomes.

To assess the cost-efficiency and expanded access of three rituximab biosimilars versus the reference rituximab from the perspective of the Jordanian national health payer. A 1-year cost-efficiency and expanded access model of conversion from reference rituximab (Mabthera) to the approved biosimilars (Truxima, Rixathon, and Tromax) to assess five metrics: total annual cost to treat a hypothetical patient; head-to-head cost comparison; changes in patients' access to rituximab; number-needed-to-convert (NNC) to provide an additional 10 patients access to a rituximab treatment; and relative amount of Jordanian Dinar (JOD) spent on rituximab options. The model included rituximab doses at 100 mg/10 ml and 500 mg/50 ml and considered both cost-saving and cost-wastage scenarios. Costs of treatments were based on the fiscal year 2022 tender prices received by the Joint Procurement Department (JPD). Rixathon was associated with the lowest average annual cost per patient (JOD2,860) across all six indications among all rituximab comparators, followed by Truxima (JOD4,240), Tromax (JOD4,365) and reference Mabthera (JOD11,431). The highest percentage of patient access to rituximab treatment (321%) was achieved when switching patients from Mabthera to Rixathon in the RA and PV indications. At four patients, Rixathon was associated with the lowest NNC to provide an additional 10 patients access to rituximab treatment. For each JOD1 spent on Rixathon, an additional JOD3.21 must be spent on Mabthera, an additional JOD0.55 on Tromax, and an additional JOD0.53 on Truxima. Rituximab biosimilars were associated with cost savings in all approved indications in Jordan compared to reference rituximab. Rixathon was associated with the lowest annual cost, the highest percentage of expanded patient access for all six indications, and the lowest NNC providing 10 additional patients with access.

Pimavanserin (PIM) is the only FDA approved atypical antipsychotic (AAP) for the treatment of Parkinson's Disease Psychosis (PDP) while other off-label AAPs like quetiapine (QUE) are also used. Real-world comparative effects of PIM and QUE on health resource utilization (HCRU) may provide insights about their relative benefits. To examine annual HCRU among newly initiated PIM or QUE monotherapy among patients with PDP. Retrospective analysis of 100% Medicare (Parts A, B, and D) claims of patients with PDP during 1 January 2013 to 31 December 2019 was conducted. Treatment-naive patients with first prescription for PIM or QUE from 1 January 2014 to 31 December 2018 were selected if they had ≥12-months continuous monotherapy and had no prior AAP use for ≥12-month pre-index. Post-index 12-month HCRU was compared between 1:1 propensity score matched (PSM) PIM or QUE cohorts. HCRU outcomes included: rates of all-cause and psychiatric-related inpatient hospitalizations by stay-type [i.e., long-term stays (LT-stays), short-term stays (ST-stays), skilled nursing facility stays (SNF-stays)], outpatient hospitalizations, emergency room (ER) visits, and office visits. Relative risk and 95% confidence intervals are reported [RR (95% CI)]. A total of 842 and 7,116 were treated with PIM and QUE, respectively. Mean age and gender distribution were similar among both groups. After PSM, those on PIM (n=842) had significantly lower RR for all-cause: inpatient hospitalizations [RR=0.78 (0.70–0.87)], ST-stays [RR=0.75 (0.66–0.84)], SNF-stays [RR=0.64 (0.54–0.76)], and ER visits [RR=0.91 (0.84–0.97)] vs. QUE (n=842). PIM patients had slightly higher RR for all-cause office visits [RR=1.03 (1.01–1.05)] vs. QUE. Psychiatric-related inpatient hospitalizations were also lower for PIM vs. QUE: [RR=0.63 (0.48–0.82)] ST-stays [RR=0.61 (0.43–0.86)], SNF-stay [RR=0.69 (0.47–1.02)], and ER visits [RR=0.53 (0.37–0.76)]. In this analysis of PDP patients, PIM monotherapy resulted in nearly 22% and 37% lower all-cause hospitalizations and psychiatric-related inpatient hospitalizations compared to QUE.

The National Health Service (NHS) in England is facing extreme capacity pressures. The backbone of prostate cancer care is gonadotropin-releasing hormone agonist (GnRHa) therapy, commonly administered every month or 3 months. We estimated the cost and capacity savings associated with increased use of 6-monthly GnRHa therapy in England. A capacity and cost-minimization model including a societal perspective was developed (in Microsoft Excel) to generate cost and capacity estimates for GnRHa drug acquisition and administration for "Current practice" and for a "Base case" scenario. In the "Base case" scenario, 50% of patients who were receiving monthly or 3-monthly GnRHa therapy in "Current practice" switched/transitioned to a 6-monthly formulation. Cost/capacity estimates were calculated per patient per administration and scaled to annualized population levels. Sensitivity analyses were conducted to assess the impact of individual model assumptions: 1 tested the impact of drug acquisition costs; 2 and 3 tested the level of nurse grade and the time associated with treatment administration, respectively; 4 tested the rate of switch/transition to 6-monthly GnRHa therapy; and 5 tested differing diagnostic patterns following the coronavirus disease 2019 pandemic. Compared with "Current practice", the "Base case" scenario was associated with annual cost savings of £5,164,296 (148,478 fewer appointments/year and 37,119 fewer appointment-hours/year). The largest savings were in drug administration (£2.2 million) and acquisition (£1.6 million) costs. Annual societal cost savings totaled £1.4 million, mainly in reduced appointment-related travel, productivity and leisure time opportunity losses. Increased use of 6-monthly versus monthly or 3-monthly GnRHa therapy consistently achieved system-wide annual cost and capacity savings across all sensitivity analysis scenarios. Our holistic model suggests that switching/transitioning men from monthly or 3- monthly GnRHa therapy to a 6-monthly formulation can reduce NHS cost and capacity pressures and the societal and environmental costs associated with prostate cancer care. Men with prostate cancer often receive hormone injections to slow their cancer progression and relieve their symptoms. In England, most men who are prescribed hormone injections receive them once every month or 3 months; however, a 6-monthly option would reduce the number of injection appointments required each year. If some men who are receiving hormone injections every month or every 3 months switched to treatment once every 6 months, it could reduce the impact of prostate cancer treatment on their lives. It might also reduce the demands of prostate cancer treatment on the National Health Service (NHS). We developed a computer-based model to assess how NHS costs and nursing would be affected if half of the men in England who are receiving hormone injections every month or 3 months switched to injections every 6 months. According to our model, this change could save the NHS about £5.2 million each year. The main cost savings would be in reduced nursing costs. The change would also benefit the NHS because nurses would have almost 150,000 fewer injections to give, meaning that they could spend their time providing care elsewhere. Given that men would have to attend fewer appointments, they would also benefit from reduced time traveling, which would benefit the environment as well. Overall, these benefits to society would contribute about £1.4 million of savings per year. Given how stretched the NHS is in England, particularly after the COVID-19 pandemic, opportunities to reduce time and staffing pressures are very important. [ABSTRACT FROM AUTHOR]

There is an ongoing debate among researchers and policy-makers on how to make transparency a powerful tool of healthcare systems. This study addresses how the availability and accessibility of information about medical services to the general population affects healthcare outcomes in Russia. A systematic review was conducted and reported according to the Preferred Reporting Items for Systematic Reviewing and Meta-Analysis (PRISMA) guidelines. Transparency indicators of health facilities used in the world's most efficient healthcare systems are also reviewed. Although the increase of transparency in the Russian healthcare system is considered as a tool for improving its efficiency, very little has been done to improve the actual level of transparency. The existing institutional specifics of the Russian healthcare system impose serious restrictions on acceptable levels of transparency. In the reviewed empirical Russian studies, transparency is often viewed simplistically as either information available on the websites of medical organizations or issues related to the amount of accessible indicators of compulsory medical statistical reporting. The novelty of this study consists in (a) reviewing the most recent studies on the topic and (b) including studies in Russian in the analysis. We elaborate on general and specific policy implications for improving transparency-driven outcomes in the Russian healthcare system. [ABSTRACT FROM AUTHOR]

In Canada, a persistent barrier to achieving healthcare system efficiency has been patient days accumulated by individuals with an alternate level of care (ALC) designation. Transitional care units (TCUs) may address the capacity pressures associated with ALC. We sought to assess the cost-effectiveness of a nursing home (NH) based TCU leveraging existing infrastructure to support a hospitalized older adult's transition to independent living at home. This case-control study included frail, older adults who received care within a function-focused TCU following a hospitalization between 1 March 2018 and 30 June 2019. TCU patients were propensity score matched to hospitalized ALC patients ("usual care"). The primary outcome was days without requiring institutional care six months following discharge, defined as institutional-free days. This was calculated by excluding all days in hospitals, rehabilitation facilities, complex continuing care facilities and NHs. Using the total direct cost of care up to discharge from TCU or hospital, the incremental cost-effectiveness ratio was calculated. TCU patients spent, on average, 162.0 days institution-free (95% CI: 156.3–167.6d) within six months days post-discharge, while usual care patients spent 140.6 days institution-free (95% CI: 132.3–148.8d). TCU recipients had a lower total cost of care, by CAN$1,106 (95% CI: $–6,129–$10,319), due to the reduced hospital length of stay (mean [SD] 15.6d [13.3d] for TCU patients and 28.6d [67.4d] days for usual care). TCU was deemed the more cost-effective model of care. The main limitation was the potential inclusion of patients not eligible for SAFE in our usual group. To minimize this selection bias, we expanded the geographical pool of ALC patients to patients with SAFE admission potential in other area hospitals. Through rehabilitative and restorative care, TCUs can reduce hospital length of stay, increase potential for independent living, and reduce risk for subsequent institutionalization. A persistent barrier to achieving efficiency within the Canadian healthcare system has been days accumulated by patients who no longer require the intensity of hospital care but are waiting to be discharged to more appropriate care settings. Prolonged hospital stays are known to expose patients to various health risks. Transitional care units are care settings designed to improve care continuation for patients moving between different locations or levels of care. They an opportunity to address the capacity pressures and health risks associated with prolonged hospital stays. Studies have demonstrated the effectiveness of transitional care units to improve outcomes among older adults, such as reducing hospital length of stay, nursing home placement, and falls, as well as improving functional status, quality of life, and likelihood of being discharged home. However, the financial implications of transitional care units, in terms of resources required to operate their services, and value for money are not well understood. This study found that a nursing home-based, function-focused transitional care unit reduced the length of stay in hospitals and the risk for subsequent institutionalization among frail, older adults. This was achieved at a lower total cost of care. Older adults who received transitional care were able to remain at home for three weeks longer without requiring institutional care compared to those who did not receive transitional care. Considering the growing investments in transitional care, this research provides evidence supporting nursing home-based transitional care programs. [ABSTRACT FROM AUTHOR]

This real-world retrospective database study quantified the costs of biomarker testing in a US population of patients with lung or thyroid cancers. The commercial claims IBM Marketscan database, a de-identified real-world dataset, was used to identify patients diagnosed with lung or thyroid cancer between 1/2015 and 12/2019. Eligible patients were 18 years or older with two or more lung or thyroid diagnosis codes. Patients were excluded who had evidence of prior cancer diagnoses. Subgroup analyses evaluated eligible patients with metastatic disease. Descriptive statistics were used to evaluate commercial insurance plan payer and patient out-of-pocket costs for diagnostic testing overall as well as by test procedure code and payer type. Costs were adjusted to 2020 US dollars. A total of 23,633 patients with lung cancer were eligible, 13,320 of whom had metastatic disease. There were 36,867 patients with thyroid cancer, 2,241 of whom had metastatic disease. Biomarker codes were observed among 68.4/75.8% (lung/metastatic lung) and 18.2/42.3% (thyroid/metastatic thyroid). Few patients had codes for comprehensive biomarker tests (5.2/6.7% lung/metastatic lung, 0.3/2.2% thyroid/metastatic thyroid) Among those with biomarker tests, the median per-patient total payer lifetime costs of all biomarker testing were $394/$462 (lung/metastatic lung) and $148/$232 (thyroid/metastatic thyroid). Total lifetime biomarker costs for payers ranged from a median of $128 (consumer-driven health plans) to $477 (preferred provider organizations). Median lifetime patient out-of-pocket costs were $0.00 for both tumor types and all payer types except for consumer-driven health plans ($12 for thyroid and $10 for metastatic lung). While comprehensive testing adds to the cost of biomarker testing, these data suggest the relatively low lifetime cost of biomarker testing for both payers and patients. Costs for biomarker testing should not be a limitation to access among these populations with commercial insurance plans in the US. This real-world retrospective database study found that there is a relatively low lifetime total cost of biomarker testing for the care of patients with lung or thyroid cancers. While comprehensive testing adds to the cost of biomarker testing, these data suggest the relatively low lifetime cost of biomarker testing for both payers and patients. Payer costs for biomarker testing do not appear to be limitation to access among populations with commercial insurance plans in this study. [ABSTRACT FROM AUTHOR]

Pimavanserin (PIM) is the only FDA-approved atypical antipsychotic (AAP) for hallucinations and delusions associated with Parkinson's disease psychosis (PDP). Comparative real-world analyses demonstrating its benefits are needed. To evaluate health care resource utilization (HCRU) outcomes among PDP patients treated with PIM vs. other-AAPs. Retrospective cohort analysis of Parts A, B, and D claims from 100% Medicare sample from 01 January 2013–31 December 2019 was conducted. PDP Patients initiating (i.e. index date) continuous monotherapy (PIM vs. other-AAPs) for ≥12-months during 01 January 2014–31 December 2018 without 12-months pre-index AAP use were selected after 1:1 propensity score matching (PSM) on 31 variables (sex, race, region, age, and 27 Elixhauser comorbidities). HCRU outcomes included: annual all-cause and psychiatric hospitalization (short-term stay, long-term stay, and SNF-stay [skilled nursing facility]) rates, annual all-cause and psychiatric-ER visit rates, mean per-patient-per-year (PPPY) hospitalizations, and average length of stay (ALOS). PIM and other-AAPs were compared using generalized linear models (GLM) controlled for demographic characteristics, comorbidities, coexisting-dementia, and coexisting insomnia. Of 12,164 PDP patients, 48.41% (n = 5,889) were female, and mean age was 77 (±8.14) years. Among 1:1 matched patients (n = 842 in each), 37.8% (n = 319) on PIM vs. 49.8% (n = 420) on other-AAPs (p <.05) reported ≥1 all-cause hospitalizations, respectively. Specifically, short-term and SNF-stay among PIM patients vs. other-AAPs were: 34% (n = 286) vs. 46.2% (n = 389) and 20.2% (n = 170) vs. 31.8% (n = 267) (p <.05), respectively. Similarly, 9.6% (n = 81) of PIM vs. 14.6% (n = 123) of other-AAPs patients had ≥1 psychiatric hospitalization (p <.05). Furthermore, ≥1 all-cause and psychiatric ER visit among PIM vs. other-AAPs were 61.6% (n = 519) vs. 69.4% (n = 584) and 5.2% (n = 43) vs. 10.2% (n = 86) (p <.05), respectively. PIM also had significantly lower ALOS, and mean PPPY short-term hospitalization and SNF-stays. In this analysis of PDP patients, PIM monotherapy resulted in nearly 12% and 7% lower all-cause hospitalizations and ER visits vs. other-AAPs. [ABSTRACT FROM AUTHOR]

Summary: Trichomes that originate from plant aerial epidermis act as mechanical and chemical barriers against herbivores. Although several regulators have recently been identified, the regulatory pathway underlying multicellular trichome formation remains largely unknown in tomato.Here, we report a novel HD‐ZIP IV transcription factor, Lanata (Ln), a missense mutation which caused the hairy phenotype. Biochemical analyses demonstrate that Ln separately interacts with two trichome regulators, Woolly (Wo) and Hair (H). Genetic and molecular evidence demonstrates that Ln directly regulates the expression of H.The interaction between Ln and Wo can increase trichome density by enhancing the expression of SlCycB2 and SlCycB3, which we previously showed are involved in tomato trichome formation.Furthermore, SlCycB2 represses the transactivation of the SlCycB3 gene by Ln and vice versa. Our findings provide new insights into the novel regulatory network controlling multicellular trichome formation in tomato. [ABSTRACT FROM AUTHOR]

The goal of the article is to explore the relationship between reasons for using the Internet and time spent on the Internet. The article also deals with reasons for using the Internet and exposure to bullying among adolescents. The survey was carried out on 710 secondary school students, based on a questionnaire about the habits and frequency of using information and communication technology (I.C.T.) The basic statistical values and multiple linear regression analysis were used. Based on the evaluation of the obtained data, the main reason for Internet use are video games, which confirms the first hypothesis, i.e., the relationship between the reason for using the Internet and the time spent using it. The second hypothesis can also be confirmed, i.e., that there is a significant statistical correlation between the time spent using the Internet and exposure to bullying, in the sense that certain reasons for using I.C.T. contribute to lower exposure to bullying. The results point to the resilience factors under consideration in a sense that some of these variables contribute to a shorter use of the Internet, and so to a lower exposure to bullying. Based on the obtained results it is possible to plan further preventive interventions in that sense. [ABSTRACT FROM AUTHOR]

A cantilever beam with multiple rotation spring-dampers was utilized to simulate the damped outrigger system. Two new methods, namely, the "Maxwell dampers type method" and the "virtual small mass method," were proposed to present the simplified seismic response analysis of the damped outrigger system. Corresponding dynamic characteristic equations based on the proposed methods were also given. Subsequently, H ∞ performance index was employed to obtain the optimal damper parameters. The numerical analysis shows that the proposed methods agree well with the finite-element method and have relatively accurate results. Stiffness ratios of the perimeter columns have a significant effect on the pseudo frequencies and system damping ratios. Lower stiffness ratios of the perimeter columns commonly lead to higher pseudo frequencies and system damping ratios. Furthermore, the damped outrigger system has excellent seismic mitigation performance when applied with appropriate damping parameters based on H ∞ . [ABSTRACT FROM AUTHOR]

An exhaustive and theoretical analysis for the CH3SH + H, CH3SH + CH3·, CH3CH2SH + H and CH3CH2SH + CH3· reactions has been examined using quantum chemistry theory. The potential energy surface was obtained by the CCSD(T)/CBS//M06-2X/cc-pVTZ level of theory. The overall rate coefficients have been analysed and the energetics and reaction enthalpies were also calculated. Three kinds of reaction channels have been analysed: hydrogen abstraction, SH-transfer and CH3-transfer. The calculated kinetics demonstrate that the hydrogen abstraction from the –SH group are major channels at low-temperature region (less than 1000 K). The SH-transfer channels become a competitive reaction channels with the increase in temperature. [ABSTRACT FROM AUTHOR]

Backgrounds: Biologics and JAK inhibitors were the most effective innovative systemic treatments for moderate-to-severe atopic dermatitis (AD). However, their cost-effectiveness in China remains unclear. This study aims to compare both the short- and long-term cost-effectiveness of abrocitinib and dupilumab in adults with moderate-to-severe AD from the perspective of the Chinese healthcare system., Methods: A hybrid decision tree and Markov model were developed to simulate the costs and health outcomes of interventions on both short-term and long-term horizons. Short- and long-term horizons were employed to reflect the 26-week induction treatment and model the extended 10-year maintenance treatment period, respectively. The cost-effectiveness of strategies was measured by incremental cost-effectiveness ratios (ICERs), which were then compared with the willingness-to-pay threshold (WTP) that was equivalent to the gross domestic product (GDP) per capita of China in 2023 ($12,681 [€11679.26]). One-way and probabilistic sensitivity analyses were conducted to validate the robustness of the model., Results: Over the short-term horizon, the QALYs (quality-adjusted life years) gained were 0.43 for the abrocitinib group and 0.42 for the dupilumab group, with the costs being $2,716.01 (€2501.46) and $3,940.33 (€3629.06), respectively. Over the long-time horizon, abrocitinib therapy yields higher QALYs (6.60 versus 6.53) and incurs a lower cost ($22,765.15 [€20966.81] versus $30,683.38 [€28259.54]) compared to dupilumab. The probability of abrocitinib being cost-effective was nearly 100% under the current WTP. Both short- and long-term results showed that abrocitinib was more effective and less costly than dupilumab, making abrocitinib the dominant option., Conclusions: Abrocitinib was dominant compared to dupilumab both over the short- and long-term horizon for moderate-to-severe AD in China. Future research incorporating real-world evidence and long-term efficacy outcomes could further refine these economic evaluations.

Ceramic/metal interfaces own great importance of technology, but the weak interface bond limits their applications. In this work, the effects of doping H element on the stability and bonding properties of SiC/Cu interface are studied by first principles calculations. In order to study the stability of interface, the potential surfaces were firstly studied for the C and Si terminated SiC/Cu interfaces. The C terminated interface is more stable than the Si terminated interface, which contributes the largest work of adhesion of 3.998 J/m2. The effects of hydrogen on the interface bonding properties were further studied. The occupation properties of hydrogen atoms were then studied, the hydrogen tends to occupy the octahedral position with negative formation energy. To reveal the bonding strength of SiC/Cu interface, the tensile simulations were carried out. The hydrogen owns obvious effects on the tensile strength depends on its occupation site. The movement and diffusion properties of hydrogen atoms in the interface zone were studied combining molecular dynamics and climbing image nudged elastic band method. Finally, the bonding mechanisms were analyzed by combining charge density, state density, differential charge and bader charge. Based on the above calculation results, it is found that for SiC(001)/Cu(111) interface, the H element generally has a negative impact on the bonding properties of SiC/Cu interface. • To further verify this conclusion, a model of H atom filling all octahedral gaps at the interface is established and the tensile tests are carried out. • According to the previous calculation, H4/5/6/7 systems have the lowest energy, and H5/6/7 models have close tensile properties. • Considering the computation consuming, only the H5 system is chosen for further discussions.

Corruption has become a big issue in the international trade environment with the increasing number of non-tariff barriers. The cost of corruption in customs administrations around the world has been estimated to be at least USD 2 billion. When stringent regulations become barriers to firms, they sometimes bribe government officials to get things done. Using firm-level data covering 11 Asian countries, this study sets out to quantify the impact of customs and other trade regulatory barriers on the firms' decision to bribe. Endogenous treatment model has been accommodated to address possible endogeneity problems usually inherited in this kind of observational data. Results provide that in Asia, firms which experience difficulties with customs and other trade regulatory constraints are likely to pay more bribe amounting to 6.4% of their annual total sales than other firms. Enterprises which trust the fair functioning of their judiciary systems and enterprises with high productivity levels are less likely to bribe government officials to get things done. It is, therefore, necessary to implement policies to eliminate administrative inefficiencies especially in customs and minimize trade regulatory constraints to control trade-related corrupt practices.

Para juzgar el impacto y la relevancia de los resultados del quehacer científico, las y los investigadores son sometidos a procesos de evaluación en los que se involucran registros de publicaciones y las citas correspondientes. Para ello, algunos índices se han desarrollado. Entre ellos, los índices propuestos por Hirsch se consideran en la mayoría de los procesos de evaluación. Un análisis de ellos permite concluir que el índice h ignora la contribución relativa de un investigador en las publicaciones, especialmente en aquellas que se generan por grupos grandes, p. ej. grupos con entre 80 hasta 700 autores. Asimismo, el índice h omite, en general, libros y capítulos de libro, la contribución de un investigador en la formación de recursos humanos y la formación de grupos y participación en sociedades científicas. El índice h no considera las innovaciones técnicas, la difusión y la divulgación del conocimiento científico. De manera relevante, lo preciso es enfatizar que el índice h no toma en cuenta las contribuciones científicas que conllevan al establecimiento de políticas públicas, las cuales pueden ser estratégicas y de relevancia local, regional e inclusive nacional. Valorar la obra de un investigador basándose principalmente en su índice h no solo es limitado e injusto, sino que está distorsionando severamente las prioridades de las generaciones nuevas de científicos en México. Los científicos no debemos olvidar que somos subvencionados con recursos públicos, lo cual conlleva a no solamente ser ampliamente citados a nivel internacional, sino también a contribuir en la formación de recursos humanos, a la resolución de problemas locales, regionales y nacionales, a incidir en la generación de Políticas Públicas y en la apropiación social del conocimiento. Por lo tanto, la necesidad de gestionar un sistema que considere esos aspectos es imprescindible con el propósito de evaluar el impacto posible de la obra de cada investigador.
