Distributed online constrained nonconvex optimization in dynamic environments over directed graphs

This paper is concerned with distributed online constrained nonconvex optimization problems of minimizing a global cost function decomposed by a sum of local smooth (possibly nonconvex) cost functions. This type of problems occupy a significant component of online learning in dynamic environments which are commonly involved in time-varying (TV) digraphs. Moreover, the network topology of TV digraphs is considered to be more general where related weight matrices are permitted to be row stochastic. Aiming at tackling these intricate challenges effectively, we adopt a valid primal–dual framework decomposing the multiple coupled constraints into individual node-related constraints. Additionally, by integrating a compensation error scheme, a novel primal dual mirror descent (PDMD) algorithm is proposed which employs two sequence of variables respectively serving as compensation error terms for bidirectional mirror mapping processes between primal space and dual space. Under some wild conditions, we theoretically prove that the proposed method can sublinearly reach the stationary point. In numerical simulations, four numerical examples are used to illustrate the validity and superiority of the proposed algorithm with contrast algorithms.

Clinical management of chronic wound infections: The battle against biofilm.

Bacteria constitute the most abundant life form on earth, of which the majority exist in a protective biofilm state. Since the 1980s, we have learned much about the role of biofilm in human chronic infections, with associated global healthcare costs recently estimated at ~$386 billion. Chronic wound infection is a prominent biofilm-induced condition that is characterised by persistent inflammation and associated host tissue destruction, and clinical signs that are distinct from signs of acute wound infection. Biofilm also enables greater tolerance to antimicrobial agents in chronic wound infections compared with acute wound infections. Given the difficulty in eliminating wound biofilm, a multi-targeted strategy (namely biofilm-based wound care) involving debridement and antimicrobial therapies were introduced and have been practiced since the early 2000s. More recently, acknowledgement of the speed at which biofilm can develop and hence quickly interfere with wound healing has highlighted the need for an early anti-biofilm strategy to combat biofilm before it takes control and prevents wound healing. This strategy, referred to as wound hygiene, involves multiple tools in combination (debridement, cleansing, and antimicrobial dressings) to maximise success in biofilm removal and encourage wound healing. This review is intended to highlight the issues and challenges associated with biofilm-induced chronic infections, and specifically address the challenges in chronic wound management, and tools required to combat biofilm and encourage wound healing.

Cost Analysis of Penitentiary Systems and Comparison Between the Countries of the Council of Europe

Background: The objective was to analyze the budgets invested in prisons by the member states of the Council of Europe (CoE) and the relationships between the global cost, the cost incurred per single inmate, the number of inmates per 100,000 inhabitants (PPR), the gross domestic product (GDP) and per capita GDP. Methods: The data relating to the variables considered for the year 2020 were obtained from the SPACE-I 2021 of the CoE, the World Bank/OECD, and Eurostat. Regression models were used to evaluate the relationships between the PPR and the GDP, the daily cost per prisoner and per capita GDP, and between the PPR and the per capita GDP. A multiple correspondence analysis was performed to evaluate associations between the PPR, EU membership, cost per day, cost rate, geographical area, and inmate gender. Results: The daily expenditure per inmate in northern European countries reaches very high values, respectively: EUR 330.6 (Norway) and EUR 303 (Sweden), while, in the eastern countries, the values drop sharply (EUR 6.50 in Bulgaria and EUR 8.08 in Azerbaijani). The lowest PPR values are found in northern European countries, and the highest in the following countries: Russia, Turkey, Georgia, and Azerbaijan. Conclusions: Countries with a higher GDP per capita tend to have lower prison population rates and to invest larger amounts of funds for prison systems.

Diverse ancestry GWAS for advanced age-related macular degeneration in TOPMed-imputed and Ophthalmologically-confirmed 16,108 cases and 18,038 controls.

Age-related macular degeneration (AMD) is a leading cause of blindness with $344 billion dollars global costs. In 2016, the International Age-related Macular Degeneration Genomics Consortium devised genomic data on ∼50,000 individuals (IAMDGC 1.0) and identified 52 variants across 34 loci associated with advanced AMD in European ancestry. We have now analyzed a more densely imputed version (IAMDGC 2.0) and performed cross-ancestry GWAS in 16,108 advanced AMD cases and 18,038 AMD-free controls. This identified 28 loci at P<5×10 -8 , including two additional AMD loci compared to IAMDGC 1.0 ( SERPINA1 and CPN1 ). Fine-mapping supported one ancestry-shared signal around HTRA1/ARMS2 and nine signals around CFH without African ancestry contribution. The 52-variant genetic risk score with and the 44-variant score without CFH -variants predicted advanced AMD not only in EUR, but also in AFR and ASN (AUC=0.80/0.75, 0.65/0.64, 0.80/0.79, respectively). Our results indicate that the genetic underpinning of advanced AMD is mostly shared between ancestries.

Quantitative Characterization of Compressed Air Systems

In industrial production plants, leaks in the compressed air system (CAS) lead to significant energy losses. In view of rising global energy costs, increasing the efficiency of such systems represents considerable costcutting potential. When analyzing CASs, it is often not possible to quantify the basic consumption and leakages from the available data. For companies seeking to evaluate potential savings and enhance energy efficiency, it is crucial to quantitatively assess the efficiency of CASs in terms of leakage rate. Determining the quality is typically done at a pressure of 1 bar, which is insufficient due to the volume influence of different compressor-units used in production plants. This work focuses on the algorithmic identification of pressure drop intervals as well as the determination and graphical representation of a quantitative trend visualization for industrial pressure drop intervals over a broad pressure range. For the study, the pressures time series of four production sites were recorded within one year. Shutdown periods were identified from the raw data using four machine-learning (ML) clustering and classification methods. By segmenting the pressure drop intervals, the shutdown periods were parameterized, from which quantitative trend visualization for the pressure drop periods due to compressor shutdown could be calculated and interpreted in the context of a graphical representation. The classification methods were compared as part of this work. With an F1-score of up to 0.99 being reached, only the variance differed among the algorithms. From the temporal observation of the calculated trend visualizations, rapidly falling curves suggest an increasing system leakage.

Experimental study of a distributed active noise control system with multi-device nodes based on augmented diffusion strategy.

Recently, distributed active noise control (DANC) algorithms have been explored as a way to reduce computational complexity while ensuring system stability, thereby outperforming conventional centralized and decentralized algorithms. Most existing DANC algorithms assume that each node has only one pair of loudspeaker and microphone, limiting their flexibility in practical applications. In contrast, this paper proposes a DANC algorithm with general multi-device nodes based on the recently developed augmented diffusion strategy, allowing flexible and scalable ANC applications. A real-time distributed ANC system based on a multi-core digital signal processor platform is developed in order to compare the control performance of the proposed extended augmented diffusion algorithm with that of existing centralized, decentralized and augmented diffusion algorithms. Real-time experiments demonstrate that the proposed algorithm exhibits noise reduction performance consistent with that of the centralized algorithm while achieving lower global computational complexity and avoiding the system instability risk of the decentralized algorithm. Further, the new algorithm improves convergence speed and reduces the global communication cost compared to the previous augmented diffusion algorithm. Experimental results indicate the application potential of the proposed DANC algorithm for a generalized system configuration.

The impact of sodium glucose co-transporter 2 inhibitors and glucagon-like peptide 1 receptor agonists on insulin utilisation and costs in Australia: a national retrospective observational cross-sectional study

Global insulin requirements for type 2 diabetes were predicted to increase by more than 20% from 2018 to 2030. However, this did not anticipate the rapid increase in use of glucagon-like peptide-1 receptor agonists and sodium-glucose cotransporter 2 inhibitors that has occurred over recent years. The current study aims to examine changes in insulin utilisation and costs in Australia from 2003 to2023. We conducted a large-scale observational study of national insulin utilisation and expenditure in Australia from 2003 to 2023 using the Australian Pharmaceutical Benefits Scheme. The proportion of insulin-treated people with type 2 diabetes between 2013 and 2023 was estimated using National Diabetes Services Scheme data. Joinpoint models and interrupted time series analysis were used to examine utilisation trends. Insulin utilisation (units of insulin per person with diabetes) increased by an average of 2.71% per annum (95% CI 1.97, 3.73) from 2003 to 2015, then fell by 2.70% per annum (95% CI-4.55,-1.39) from 2015 to 2023. The proportion of insulin-treated people with type 2 diabetes increased by 1.00% per annum (95% CI 0.81, 1.25) from 2013 to 2020, then fell by 0.66% per annum (95% CI-1.62,-0.04) from 2020 to 2023. A 43% reduction in inflation-adjusted insulin expenditure was observed between 2015 and 2023 due to a combination of reduced utilisation and reduction in the price of insulin glargine. Projected global insulin requirements and costs may be less than previously anticipated if reduced use of insulin in Australia is similarly observed in other countries. No funding was received for this study.

Harnessing iron tailings as supplementary cementitious materials in Limestone Calcined Clay Cement (LC3): An innovative approach towards sustainable construction

The increasing demand for sustainable construction materials has led to the exploration of iron tailings (ITs) as supplementary cementitious materials (SCMs) in Limestone Calcined Clay Cement (LC3). This study investigates the effects of varying ITs content in LC3 on compressive strength, microstructure, and environmental impact. Replacing 28 % of LC3 with ITs resulted in a 42 MPa compressive strength after 28 days, comparable to ordinary Portland cement (OPC), while reducing OPC content by 50 %. Microstructural analysis revealed that ITs contributed to the formation of additional C-(A)-S-H gel, enhancing the mechanical properties of the cement matrix. The findings also showed that concentrations of Zn (0.003–0.094 mg/L), Pb (0.002–0.090 mg/L), Cu (0.005–0.018 mg/L), Mn (0.115–0.712 mg/L), Ni (0.011–0.021 mg/L) in the leachates of LC3 containing ITs were below the critical limits for surface water and groundwater. Moreover, the life cycle assessment (LCA) demonstrated significant reductions in global warming potential (43.6 %), energy consumption (37.2 %), and cost (35.5 %). This study provides an innovative solution for waste utilization and environmentally friendly cement production.

Experimental analysis and optimization of kenaf fiber-lateritic bricks using glass powder as partial cement replacement

The rising global cost of housing demands innovative solutions to improve construction materials and reduce expenses, making affordable housing more attainable. This study investigates the synergistic benefits of eco-friendly additives—kenaf fiber and glass powder—in masonry applications aimed at affordable housing solutions. The aim is to identify the effect of different kenaf fiber and glass powder proportions on lateritic brick. Kenaf fiber was incorporated into a cement-lateritic clay mix at varying percentages (0.5 %, 1.0 %, 1.5 %, and 2.0 %), while glass powder replaced cement at levels of 10 %, 20 %, 30 %, and 40 %. The reference mix was prepared as 20 % cement, 20 % sand, and 60 % laterite clay while the water/cement ratio was maintained at 0.4. Results indicate that kenaf fiber and glass powder significantly improve compressive, flexural, and splitting strengths compared to the reference mix. However, kenaf fiber exhibits a reduction in ultrasonic velocity. The dosage of kenaf fiber and glass powder profoundly influences the hybrid material properties. The study has revealed that 4 % of glass powder and 1 % of kenaf fiber highly improved the compressive strength, flexural strength and ultrasonic velocity of the mixes. On the other hand, 4 % of glass powder and 1.5 % of kenaf fiber highly improved the splitting strength of the material. These results were supported by a predictive model validated against experimental data. Optimization reveals an optimum mix with 20.44 % cement replacement (comprising 15.91 % cement, 4.08 % glass powder, and 1.19 % kenaf fiber), 20 % sand and 58.80 % clay, offering balanced performance for masonry bricks in affordable mass housing construction.

Cumulative Tariff Cost Rate and Structure in the Global Value Chain: A Theoretical and Empirical Study

Abstract This paper constructs a more unified measurement framework from the perspective of the Leontief inverse matrix and Ghosh inverse matrix (Ghosh). At the same time, referring to the four-term decomposition method of Leontief inverse matrix in Muradov (2016), this paper analyzes the structural decomposition of the cumulative tariff cost rate. Results show that (1) Overall, from 2000 to 2017, China’s cumulative tariff cost rate, direct tariff cost rate, and multi-stage tariff cost rate all showed a downward trend, and the decline was greater than that of other countries (regions). China has strictly fulfilled its WTO accession commitments and has greatly reduced the tariff rate on imported intermediate goods. (2) With China’s deep participation in the global value chain, the amplification effect of China’s tariffs has increased from 2.57 in 2000 to 3.17 in 2017, and there is a certain degree of “amplification effect” (above 1.5) in tariffs in all countries in the world. (3) From the perspective of the contribution rate of various countries in the world, China contributes the most to the global cumulative tariff cost rate, which is due to the complexity of the global production network structure, rather than the excessively high tariff rate imposed by China on imported intermediate goods. In terms of policy implications, if China did not take the initiative to reduce tariffs, the structural changes in the global production network would lead to a larger global cumulative tariff cost rate.

Family function, psychological distress and burden in informal caregivers of people with dementia

Abstract Background Dementia presents a public health priority due to its high global prevalence, mortality, economic cost, and caregiver burden (CB). Dementia care can be stressful and may negatively influence the health of informal caregivers. This cross-sectional study aimed to identify psychological and social factors associated with subjective CB in informal home care providers of people with dementia (PwD), controlling for sociodemographic, clinical, and care-related variables. Methods We included 115 informal caregivers of PwD from community settings (mean age: 54.0±12.4 years; 81.7% women). Participants fulfilled the Zarit Burden Interview (ZBI-12), the Patient Health Questionnaire (PHQ-9), the Generalized Anxiety Disorder Scale (GAD-7), the Family APGAR, and the short IQCODE used to assess dementia severity. Multiple linear analyses were used to analyse the data. Results The mean caregiving duration was 4.8±4.8 years, and 55.7% of informal caregivers extend care for &amp;gt;40 hours/week. We found that a total of 52.5 % of informal caregivers experienced a high CB (ZBI-12 cut-off score: 17). Univariate analyses showed an association between depression (β = 0.36; p &amp;lt; 0.001), anxiety (β = 0.52; p &amp;lt; 0.001), family dysfunction (β = 0.36; p &amp;lt; 0.001), and CB. Regression analyses showed that CB was the most strongly associated with anxiety (β = 0.51; p &amp;lt; 0.001). This association weakened (0.47; p &amp;lt; 0.01) when family function was added to the final model (β=-0.22; p &amp;lt; 0.05). The final model explained 23.5% of the variance in CB. No associations between the caregiver's age, sex, caregiving duration, the extent of care per day, use of community care, dementia severity, and depression were identified. Conclusions Long-term care for people living with dementia can be very demanding. Thus, the implementation of tailored interventions to enhance family function and diminish psychological distress can mitigate level of caregiver burden. [Grant support: APVV-22-0587]. Key messages • Dementia caregiving is a global public health priority. • The caregiver’s burden and distress can be alleviated by the interventions focusing on family dysfunction.

Distributed Optimization on Matrix‐Weighted Networks

ABSTRACTThis article is intended to tackle the optimization problems for continuous‐time first‐order and second‐order multi‐agent systems (MASs) operating over matrix‐weighted networks. A matrix‐weighted network serves as a powerful framework to model the interdependence among agents' multidimensional states, providing an effective approach to analyze smart grids, intelligent transportation systems, and so forth. Our optimization objective is to facilitate the convergence of all agents toward the optimal value of a global cost function, which is formed by a sum of local cost functions. To achieve this goal, distributed optimization algorithms based on Hessian matrix and gradient information are constructed. Additionally, an edge‐based event‐triggered mechanism is utilized to avoid communicating with all neighbors at the time of event triggering. It is proved that this mechanism theoretically excludes Zeno behavior. The results show that the proposed algorithms ensure that the agents can achieve the optimization goal while reducing energy consumption. Finally, an application is presented to substantiate the theoretical results.

Predictive alternating runs and random task-switching sequences produce dissociative switch costs in the Consonant-Vowel/Odd-Even task.

Task-switching is commonly used to investigate working memory and attentional control processes. The current study compares predictive versus non-predictive task-sequencing effects on task-switching performance. Participants completed four blocks of the Consonant-Vowel/Odd-Even (CVOE) task: Two single task pure blocks, a predictable switch block where task switching occurred every two trials, and a random switch block where switching was unpredictable. In addition to mean error rates and response times (RTs), we assessed sequence effects on local switch costs (i.e., switch vs. nonswitch trials) and global costs (i.e., nonswitch vs. pure trials) for both error rates and RTs along with their underlying distributions. Overall, we show that while predictive and random switching produced similar patterns for mean error rates and RTs, a dissociation occurred in RT switch costs. When switching was random, local costs were inflated. In contrast, predictive switching increased global costs. Increased local costs for random versus predictive switching reflect an increase in task-setreconfiguration processes as participants struggle to reconfigure to an unpredictable task type in working memory on a subsequent trial. Separately, increased global costs for predictive switching reflect declines in task-set maintenance processes, as participants must maintain both task types in working memory while simultaneously monitoring their progress through the trial sequencing.

Nuciferine Alleviates High-Fat Diet- and ApoE-/--Induced Hepatic Steatosis and Ferroptosis in NAFLD Mice via the PPARα Signaling Pathway.

Nonalcoholic fatty liver disease (NAFLD) causes significant global mortality and healthcare costs with no recommended pharmacological intervention for clinical management. Nuciferine (Nuc) is an alkaloid with aromatic rings, abundantly found in Nelumbo nucifera Gaertn. In this study, we explored the protective mechanisms of Nuc against hepatic steatosis and ferroptosis in NAFLD. High-fat diet (HFD) and healthy male ApoE-/- mice were used to induce NAFLD and a hypercholesterolemia model. Nuc was administered to the mice for four consecutive weeks from the ninth week. Various assessments, including histopathology, RNA sequencing, lipid metabolism, and ferroptosis-related protein expression, showed that Nuc alleviated hepatic steatosis and ferroptosis. We further showed that Nuc improves fatty acid accumulation and ferroptosis through the PPARα signaling pathway in mice and RSL3-treated AML-12 cells. The PPARα inhibitor GW6471 blocked Nuc's protective effects, leading to excess accumulation of iron ions. Thus, Nuc may be a potential therapeutic agent for NAFLD.

Economic evaluation of an outsourced fourth-party logistics (4PL) under a flexible production system

Competition in the production business is getting harder day by day for the manufacturer and the corresponding retailer of the supply chain. When a supply chain deals with deteriorating products, an efficient production system, and a logistic provider are two important pillars to keep the business profitable. Logistics facility for deteriorating products requires additional attention, especially when deteriorating products require a refrigerate-storage facility. This study investigates the economic evaluation of flexible production and logistics outsourcing for deteriorating products with the help of logistics outsourcing. The retailer outsources logistics facilities through a fourth-party logistics provider. Fourth-party logistics uses reefer shipping to transport deteriorating products for preventing deterioration during transportation. The refrigerant of the shipping container has a random leakage during shipping. In the meantime, the manufacturer uses preservation facility to reduce the random deterioration rate of products. A classical optimization finds the global minimum total cost for a unique solution of decision variables. Results prove that flexible production is very sensitive to machinery systems and fresh products are more cost-effective for transportation than frozen products. The proposed system saves 38.38% of the total cost in comparison with a constant production rate. Sensitivity analysis finds transportation costs of 4PL are the most sensitive parameters of the system.

Optimization of the pipe diameters and the dynamic operation of a district heating network using a robust initialization strategy

District heating networks (DHN) are systems offering a substantial solution for the decarbonization of heat production. As these systems involve significant costs, the development of digital tools for their optimization becomes a necessity. In the literature, there is a lack of studies optimizing the sizing of the DHN while considering a dynamic operation of the system with a detailed physics. In this work, we developed a Non-Linear Programming (NLP) optimization used in a case study of a DHN where the pipe sizing and the operation are optimized with a precise modeling of the distribution network. The method of Orthogonal Collocation on Finite Elements (OCFE) was employed to discretize the partial differential equation (PDE) governing the temperature evolution in the pipes. In addition, the pressure drops were modeled using the Darcy–Weisbach equation. Three optimization criteria were used: investment cost of the pipes, operational cost, and the global cost. The optimization provided the pipe diameters that best fit each optimization criterion. Furthermore, several initializations were tested to verify if the obtained optimum was a confidence optimum and if the resolution was robust. Finally, the optimization provided a coherent response to the variation in the cost of heat production.

Global trade of green iron as a game changer for a near-zero global steel industry? - A scenario-based assessment of regionalized impacts

The currently most promising approach for reducing CO2 emissions of the global steel production is reducing iron ore in shaft furnaces with (green) hydrogen instead of blast furnaces. Unlike to the liquid iron produced in blast furnaces, the direct reduced iron produced in this route (green iron) exists in a solid state and can be transported at reasonable costs over long distances. This allows for spatial decoupling of the iron reduction step from the steelmaking step and may lead to global trade in green iron as a new intermediate product in the steelmaking value chain. This article assesses the potential impact of a global green iron trade in terms of shifting energy demand between regions and in terms of cost savings by comparing three scenarios for a global near-zero GHG steel industry: The Domestic scenario, assuming strict regional co-location of green iron and steel production; The Max Trade scenario, assuming early emergence of a global green iron market and the Intermediate Trade scenario, assuming late emergence of a global green iron market. In the trade scenarios, 12-21% of global crude steel is produced from traded green iron in 2050. 15-26 Mt/a of hydrogen consumption is relocated to global “sweet spots”, resulting in cost savings of 2.2-3.9% of the global annual steel production costs, which can provide important support for the development of net zero steel production. Enablers and barriers for global green iron trade are discussed.

Design and Synthesis of Six‐Armed Antimicrobial Polymer to Battle Against Nosocomial Pathogens

ABSTRACTThe world is under threat from microorganisms that have evolved resistance to currently available medicinal drugs and multidrug resistance among bacterial pathogens is becoming to be a serious public health issue worldwide. It is imperative to find or develop new antibiotics against Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter species (ESKAPE) pathogens because they exhibit multidrug resistance and virulence through a variety of mechanisms. ESKAPE infections are often associated with increased global healthcare costs, morbidity, and illnesses. As a result, the utilization of naturally occurring bioactive agents offers a solution since these molecules are widely available and safe to employ during their use. Ricinoleic acid, an extract of seed oil that contains an unsaturated omega‐9 fatty acid and hydroxy acid, has garnered increasing interest due to its wide‐range antibacterial properties. Herein, we report the synthesis of polyethyleneimine‐ricinoleic acid‐based polymer (PEIRA) to battle against Methicillin‐resistant Staphylococcus aureus (MRSA), Acinetobacter baumannii (one among ESKAPE) and Staphylococcus aureus. The synthesized polymer showed efficient activity against MRSA, Acinetobacter baumannii, and Staphylococcus aureus. A noticeable percentage inhibition against MRSA (74%), A. baumannii (73%), and S. aureus (81%) was achieved at 2.5 mg/mL. The time‐kill assay revealed that the PEIRA polymer exhibited a bacteriostatic effect against all the tested pathogens. Cytotoxicity assay on human dermal fibroblast (HDF) cell lines revealed the PEIRA has an IC 50 of 31.7 μg/mL and exhibited above 75% cell viability at the concentration 5 and 10 μg/mL were deemed nontoxic on HDF. Based on the investigation, the synthesized PEIRA polymer may have promising applications in the biomedical sector and hospital‐acquired infections (HAIs).

Reducing the risk of social engineering attacks using SOAR measures in a real world environment: A case study

The global cost of successful cyberattacks is increasing annually, with there being a shift towards social engineering threats in recent years. Cybercriminals are increasingly targeting humans rather than technical systems, recognizing data as a critical resource, especially in the finance industry where breaches can lead to substantial losses and reputational damage. The present case study proposes measures to reduce human susceptibility to social engineering attacks, leveraging SOAR (Security Automation, Orchestration, and Response) technology for incident response automation. The study covers various issues in cybersecurity, SOAR, and social engineering, through analyzing interviews with expert practitioners in the field, addressing cybersecurity skills shortages and current cyber threats. Four social engineering vignettes were developed, representing real threats, along with specific SOAR measures implemented using Microsoft Sentinel. These measures were simulated to demonstrate their effectiveness by reducing the employee's vulnerability to social engineering attacks. The risk of social engineering attacks was successfully reduced by implementing a responsive approach through the developed SOAR measures. Some of the measures reduced the risk by locking user accounts or forcing password changes after a detected cyber incident while another measure was developed for awareness enhancements. Given the current shortage of cybersecurity professionals, technologies like SOAR are becoming increasingly relevant for security teams. However, SOAR alone cannot address all challenges posed by social engineering and should be viewed as a complementary measure rather than a standalone solution.

Lichen Sclerosus is a high-cost diagnosis, compounded by comorbid conditions

Introduction and Objective: In the past decade, there have been significant advancements in understanding the etiology, molecular mechanisms, and best treatment options for lichen sclerosus (LS). However, to date, there is a lack of published data on the costs of care, associated comorbidities, and quality of life related to the condition. Therefore, this study aims to investigate the global costs associated with the treatment of LS using a contained insurance dataset. Methods: Deidentified 12-month data from 2022 to 2023 for a northeastern private insurer of teachers and municipal workers was queried to analyze costs associated with a diagnosis of LS (ICD-10 code L90.0). Comorbidities were also queried. Descriptive statistics were utilized to describe the population’s expenditures. Johns Hopkins Adjusted Clinical Groups (ACG) risk assessment was utilized to determine future costs. Z-tests were utilized to determine the differences in rates of comorbidities, and T-tests for differences in cost. Results: The database included all 4,306 members. Average annual cost per member was $9,280, average age was 35.5 years, behavioral health prevalence was 26%, and 53% were female. Cost for members with a behavioral health condition was $18,125 (2.0-fold) and $6,219 average cost for members without (0.7-fold). LS was present in 161 (3.7%) members, with average age of 42.0, prevalence of behavioral health 37%, and 62% were female. The presence of lichen sclerosus was associated with a 3.5-fold increase in average cost per member ($32,437 annually). For those with LS and a behavioral health condition, cost was $53,539 (5.8-fold average per member) compared to $19,901 (2.1-fold average plan cost) for those with LS and no BH condition. Median cost for those with LS was $8,755 compared to $2,056 for the entire cohort which was a significant difference (P < 0.0001). Incidence of behavioral health conditions, low back pain, obesity, chronic obstructive pulmonary disease, hyperlipidemia and hypertension were increased in the LS group versus the plan population (P < 0.01). Pharmaceutical expenditure for those with LS was a median of $267.58 compared to $94.80 average for the entire cohort (P < 0.0001). Conclusions: The presence of LS in this privately insured population significantly raises costs, exacerbated by elevated rates of mental health and other comorbidities, highlighting the need for comprehensive care addressing these complexities to improve health outcomes and reduce overall expenses.
