Cost-Efficient Transcriptomic-Based Drug Screening.

Transcriptomics allows to obtain comprehensive insights into cellular programs and their responses to perturbations. Despite a significant decrease in the costs of library production and sequencing in the last decade, applying these technologies at the scale necessary for drug screening remains prohibitively expensive, obstructing the immense potential of these methods. Our study presents a cost-effective system for transcriptome-based drug screening, combining miniaturized perturbation cultures with mini-bulk transcriptomics. The optimized mini-bulk protocol provides informative biological signals at cost-effective sequencing depth, enabling extensive screening of known drugs and new molecules. Depending on the chosen treatment and incubation time, this protocol will result in sequencing libraries within approximately 2 days. Due to several stopping points within this protocol, the library preparation, as well as the sequencing, can be performed time-independently. Processing simultaneously a high number of samples is possible; measurement of up to 384 samples was tested without loss of data quality. There are also no known limitations to the number of conditions and/or drugs, despite considering variability in optimal drug incubation times.

Contemporary national outcomes of hyperbaric oxygen therapy in necrotizing soft tissue infections.

BACKGROUND: The role of hyperbaric oxygen therapy (HBOT) in necrotizing soft tissue infections (NSTI) is mainly based on small retrospective studies. A previous study using the 1998-2009 National Inpatient Sample (NIS) found HBOT to be associated with decreased mortality in NSTI. Given the argument of advancements in critical care, we aimed to investigate the continued role of HBOT in NSTI. METHODS: The 2012-2020 National Inpatient Sample (NIS) was queried for NSTI admissions who received surgery. 60,481 patients between 2012-2020 were included, 600 (<1%) underwent HBOT. Primary outcome was in-hospital mortality. Secondary outcomes included amputation, hospital length of stay, and costs. A multivariate model was constructed to account for baseline differences in groups. RESULTS: Age, gender, and comorbidities were similar between the two groups. On bivariate comparison, the HBOT group had lower mortality rate (<2% vs 5.9%, p<0.001) and lower amputation rate (11.8% vs 18.3%, p<0.001) however, longer lengths of stay (16.9 days vs 14.6 days, p<0.001) and higher costs ($54,000 vs $46,000, p<0.001). After multivariate analysis, HBOT was associated with decreased mortality (Adjusted Odds Ratio (AOR) 0.22, 95% CI 0.09-0.53, P<0.001) and lower risk of amputation (AOR 0.73, 95% CI 0.55-0.96, P = 0.03). HBO was associated with longer stays by 1.6 days (95% CI 0.4-2.7 days) and increased costs by $7,800 (95% CI $2,200-$13,300), they also had significantly lower risks of non-home discharges (AOR 0.79, 95%CI 0.65-0.96). CONCLUSIONS: After correction for differences, HBOT was associated with decreased mortality, amputations, and non-home discharges in NSTI with the tradeoff of increase to costs and length of stay.

Barriers to cervical cancer screening in Africa: a systematic review.

INTRODUCTION: Africa has one of the highest burdens of cervical cancer in the world. The unacceptably high incidence and mortality rates could be reduced through implementing a comprehensive approach to its prevention and control that includes screening, which however, is low in most low-and-middle-income countries. Hence, this systematic review aims at exploring factors that prevent women from utilising cervical cancer screening services in the region. METHODS: A mixed method systematic review was conducted. A search was performed on PubMed (Medline), EMBASE, CINAHL (EBSCOHOST) and Scopus databases for articles published until May 2019 without time, language or study design limits. Two reviewers critically appraised the included studies independently using the standard quality assessment criteria for evaluating primary research papers. Results of the quantitative and mixed methods studies were transformed into qualitative data and synthesised using thematic analysis. RESULTS: From a potential 2 365 studies, 24 from 11 countries met the eligibility criteria and were selected; eight qualitative, 13 quantitative, and three that used the mixed-method approach. The primary barriers were identified as poor access to screening services, lack of awareness and knowledge on cervical cancer and screening, and socio-cultural influences. Service providers perceived lack of skills, screening equipment and supplies, and staff shortages as the major barriers to the provision of screening services. CONCLUSION: Barriers to cervical cancer screening in Africa are multifaceted and require a holistic approach that will address them concurrently at the health system, individual, interpersonal, community and structural levels. Political will complimented by stakeholder involvement is required in the development and implementation of strategies that will ensure acceptability, availability, accessibility, and affordability of screening to minimise barriers in accessing the service.

Oil price uncertainty, oil pricing reform, and corporate profitability: The case of China.

This study investigates the impact of oil price uncertainty (OPU) on corporate profitability in China, the world's largest crude oil consumer. Most importantly, we examine how the Chinese government's oil price reform affects this relationship. Using the yearly data of Chinese-listed companies, we find that the uncertainty of oil prices negatively affects corporate profitability but positively impacts operating expenses from 2007 to 2020. This finding holds after robust tests, including alternative profitability metrics and endogeneity model. Most interestingly, implementing the 2013 market-oriented oil pricing reform amplifies the adverse impact of OPU on corporate profitability owing to increased operating costs in the post-2013 period. Moreover, the detrimental effect of uncertain oil prices on corporate profitability is less prominent for large-capitalized companies. This research adds to the body of knowledge on the factors affecting corporate profitability by highlighting the volatility effect of oil prices and government pricing mechanisms. The results offer grounds for legislators and corporate managers to consider how to control the uncertainty surrounding oil price matters to ensure stable corporate profitability.

Firm-Level and Public-Sector Costs Make Small-Scale Maize Flour Fortification Challenging in Uganda.

BACKGROUND: Maize flour in Uganda is milled by hundreds of enterprises, mostly small- (5-20 metric tons [MT]/day) and micro-scale (<5 MT/day) mills or firms. A mandatory maize flour fortification program exists for medium-scale mills (>20 MT/day) and policymakers are considering including smaller-scale millers. OBJECTIVE: We estimated the private and public costs of maize flour fortification at different scales and explored their implications for extending the mandatory fortification to include smaller-scale mills. METHODS: We used secondary data on the structure of the maize flour market and primary data on milling and fortification costs to estimate mill and regulatory costs at 3 scales of flour production: micro, small, and medium. RESULTS: For micro-, small-, and medium-size operations, respectively, operational costs of fortification were US$13, US$9, and US$7 per metric ton (MT) of maize flour, which represented 20%, 16%, and 16% of annual operating costs, and the ratio of fortification equipment cost to mill equipment costs was higher for micro-scale mills (2.7) than for small- (0.38) and medium-scale (0.54) maize mills. Governmental regulatory costs rise if smaller-scale mills are included due to the increased number of facility inspections. CONCLUSIONS: Fortification and regulatory costs increase as production scale decreases. Up-front capital costs of fortification would be daunting for micro- and small-scale mills. Medium-scale mills, which supply social protection programs, might be able to manage fortification costs and other challenges. Decision-makers should consider all costs and cost burdens, and the realities of enforcement capabilities before expanding fortification programs to include smaller-scale operations.

Plain language titleCosts of Small-scale Maize Flour Fortification in UgandaPlain language summaryA study of the costs of adding vitamins and minerals by small-scale maize flour millers in Uganda was undertaken to understand if it would be commercially beneficial from a business and operations perspective for them to do so, and if requiring them to do so would impose additional cost burdens on government to ensure that fortification standards were met.Why was the study done?Maize flour is consumed by the majority of Uganda's population, especially the rural poor. If the flour were fortified, it would reduce vitamin and mineral deficiencies among those at risk. The most important constraint to market-wide fortification is the presence of many small-scale mills or firms that neither have the resources nor the technology to adopt and sustain the fortification process. To date, no study has been done to calculate the costs that small-scale mills would have to face to fortify flour, or what the cost implications for government would be for including smaller-scale mills in a national fortification program, including the costs of enforcing regulations.What did the researchers do?The researchers interviewed millers of several scales of operation to collect cost information on their operations and interviewed representatives of government regulatory bodies to estimate the costs of testing maize flour to ensure compliance with regulations. Researchers estimated the cost to the mills of adding fortification to their business models, and the impacts on the government costs (eg, testing additional samples, etc.) of including smaller-scale mills in the fortification program.What did the researchers find?The researchers looked at 3 different types of mills based on their capacity to mill maize flour­micro-scale firms milled less than 5 metric tons (MT) a day, small-scale firms milled 5 to 20 MT per day, and medium-scale firms milled over 20 MT a day. For micro-, small-, and medium-size firms, respectively, fortification increased operational costs by US$13, US$9, and US$7 per MT of maize flour, which represented 20%, 16%, and 16% of annual operating costs. Similarly, governmental regulatory costs rose if smaller-scale mills were included because of the increased number of facility inspections required since the current legislation requires mandatory annual inspections.What do the findings mean?Fortification and regulatory costs increase as the scale of production by the millers decreases. If fortification by small- and micro-scale mills were made mandatory, up-front costs of fortification equipment and materials would be daunting for micro- and small-scale millers. Ugandan medium-scale millers might manage fortification costs and other challenges, but only if the social protection programs they supplied were of sufficient volume and regularity.

Modelling policies to improve affordability and consumption of nutritious foods for complementary feeding in Kenya.

In Kenya 26% of children under age 5 experience stunted growth, 4% are wasted and 11% are underweight. In pregnant women, the prevalence of iron deficiency is 36% and iron-deficiency anaemia prevalence is 26%. Previous studies have identified affordability as a key barrier to the intake of nutrients, particularly from animal-source foods (ASFs). Thus, this study analyzes to what extent the affordability of ASF in Kenya can be improved. It focuses on four ASFs: eggs, milk, chicken and beef. Using a computable general equilibrium model, three policy simulations were undertaken to establish the impact of potential changes on nutritious ASF availability and affordability: a 20% increase in total factor productivity (TFP) for the four products; a 20% TFP increase plus a 25% reduction in trade and transportation margins; and a 20% TFP increase for ASF and maize (a key input in animal feed). Simulations suggest increasing the productivity of the four ASF products would increase their availability and lower consumer prices (up to 17% lower). Household consumption of the four commodities would increase, resulting in improved household dietary diversity. Rural households would gain more compared with urban households. Poor households (the lowest 40%) would register larger welfare (Equivalent Variation) gains than other households in both urban and rural areas. The richest 20% of the population would neither lose nor gain following the policy changes. Reducing transportation costs and trade margins and increasing maize productivity could further reduce the price of ASFs through lower production costs and increased consumption.

Comparative life cycle cost analysis of bio-valorized magnetite nanocatalyst for biodiesel production: Modeling, optimization, kinetics and thermodynamic study.

An active, high surface area, recyclable, magnetic, basic, iron oxide-based nanocatalyst was developed from banana leaves waste and used for microwave-assisted transesterification of soybean oil to biodiesel. According to the Hammett indicator, the catalyst has a high total basicity of 15 < H < 18.4. After optimization through the response surface methodology, the reaction allows 96.5 % biodiesel yield in the presence of 24:1 methanol to soybean oil molar ratio, 6 wt% BLW@Fe3O4, 0.5 h at 65 °C. The magnetic nature of the catalyst improves reusability for up to 6 cycles. Thermodynamic analyses showed that transesterification of soybean oil to biodiesel is an endothermic reaction. Moreover, the catalyst has the potential to reduce biodiesel production costs by utilizing abundant biomass waste materials. The calculated cost for 1 kg of catalyst is $1.14, while the biodiesel's cost per kg produced in this work is merely $1.05, showing high commercial viability.

Failure to Participate in Sports: An Evaluation of Preparticipation Physicals in a Local School District.

PURPOSE: To determine the incidence of the documentation of athlete failure of preparticipation sports physicals. METHODS: This was a retrospective observational study that involved review of preparticipation examination physical form documentation from multiple clinicians for all student athletes who participated in athletics during the 2018 to 2019 academic year at Galveston Independent School District (GISD). We collected the reasons for failure to pass the preparticipation physical examination. RESULTS: Of the approximately 800 student athlete forms reviewed, 183 forms indicated individual athletes failed the visual acuity or cardiovascular portions of the preparticipation physical examination. DISCUSSION: Athlete failures of the preparticipation physical examination may cause delays in sports participation, and time and monetary costs to students and their parents. Inconsistences in guidelines used to clear athletes as well as variation in form completion impacts whether athletes reportedly failed or passed the examination. Mass participation screening becomes a safety net for communities for athletes who may not have primary care providers to encourage follow-up with a regular clinician for previously undiagnosed medical issues and standardizing guideline use and form completion across clinicians who do these exams may improve numbers of athletes who are cleared to play sports. CONCLUSION: Focusing on preventable and addressable preparticipation examination failures may help clinicians who perform these exams, while also establishing a safety net for previously undiagnosed medical conditions. Instituting yearly vision checks, addressing cardiovascular issues, and encouraging yearly follow-up with primary care clinicians can more readily address physical and mental health issues and will provide more comprehensive care to student athletes.

Cost Analysis and Financial Implications of a Peritoneal Surface Malignancy Program in the USA.

BACKGROUND: We aimed to describe the financial implications of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) in the USA. MATERIALS AND METHODS: We conducted a retrospective cost analysis of 100 CRS/HIPEC procedures to examine the impact of patient and procedural factors on hospital costs and reimbursement. A comparison of surgeons' work relative value units (wRVUs) between CRS/HIPEC and a representative sample of complex surgical oncology procedures was made to assess the physicians' compensation rate. Univariable and multivariable backward logistic regression was used to analyze the association between perioperative variables and high direct cost (HDCs). RESULTS: The median direct cost per CRS/HIPEC procedure was US $44,770. The median hospital reimbursement was US $43,066, while professional reimbursement was US $8608, resulting in a positive contribution margin of US $7493/procedure. However, the contribution margin significantly varied with the payer mix. Privately insured patients had a positive median contribution margin of US $23,033, whereas Medicare-insured patients had a negative contribution margin of US $13,034. Length of stay (LOS) had the most significant association with HDC, and major complications had the most significant association with LOS. Finally, CRS/HIPEC procedures generated a median of 13 wRVU/h, which is significantly lower than the wRVU/h generated by open pancreatoduodenectomies, open gastrectomies, and hepatectomies. However, higher operation complexity and multiple visceral resections help compensate for the relatively low wRVU/h. CONCLUSIONS: CRS/HIPEC is an expensive operation, and prolonged LOS has the most significant impact on the total cost of the procedure. High-quality care is essential to improve patient outcomes and maintain the economic sustainability of the procedure.

Physiological responses of tambaqui (Colossoma macropomum) fed diets supplemented with silage from fish and vegetables residues / Respostas fisiológicas de tambaqui (Colossoma macropomum) alimentado com dietas suplementadas com silagem de resíduos de pescado e vegetais

The demand for products to replace high-cost raw materials, such oil and fish meal, in the manufacture of feed for use in aquaculture, while also guaranteeing the nutritional quality of the diets, is increasing. Silage produced with fish and vegetables residues is a low-cost and efficient protein source. The objective of the present study was to evaluate the physiological and biochemical responses of tambaqui fingerlings fed four different levels of silage included in commercial feed with 28% crude protein, over two periods: 45 and 90 days. Each treatment was carried out over three replications, with 10 tambaqui in each 100 L experimental tank. At the end of each established period, blood samples were collected from five animals from each repetition to determine the hematological and biochemical variables. Body weight and total length, hepatosomatic and liposomal indices and hematocrit of specimens fed with diets supplemented with silage did not exhibit significant changes in both assessment period. After 45 days of feeding, the hemoglobin concentration increased when tambaqui were fed a diet including 20% silage. The red blood cell count, mean corpuscular volume and mean corpuscular hemoglobin did not change between treatments in either period. The total protein concentrations increased significantly in the plasma of tambaqui fed with diets with the inclusion of 5 and 10% of silage, evaluated after feeding for 45 days. It was found that the groups which had silage included in their diet did not exhibit significant alterations in the evaluated parameters, and the diet was therefore not consider harmful to the health of tambaqui. Therefore, the use of silage as a feed supplement during tambaqui farming is a sustainable alternative for producers, as it leads to a reduction of impacts of fish and vegetables waste disposal.

A procura por insumos que substituam produtos de alto custo, como óleo e farinha de peixe, na fabricação de rações para uso na aquicultura é crescente, sendo necessário garantir a qualidade nutricional das dietas. A silagem produzida a partir de resíduos de pescado e de vegetais apresenta-se como uma alternativa de baixo custo e eficiente fonte proteica. O objetivo do presente estudo foi avaliar as respostas fisiológicas e bioquímicas de alevinos de tambaqui alimentados com quatro níveis de inclusão de silagem em ração comercial com 28% de proteína bruta, em dois períodos: 45 e 90 dias. Cada tratamento foi realizado em três repetições, com 10 tambaquis em cada caixa experimental de 100 L. Ao término de cada período estabelecido, amostras sanguíneas foram coletadas de cinco animais de cada repetição para determinação das variáveis hematológicas e bioquímicas. Peso, comprimento total e índices hepatossomático e lipossomático de espécimes alimentados com silagem não mostraram alterações significativas em ambos os períodos de avaliação, bem como os valores de hematócrito. A concentração de hemoglobina de tambaqui após 45 dias de alimentação aumentou quando foi fornecida dieta com inclusão de 20% de silagem. A contagem de eritrócitos, volume corpuscular médio e hemoglobina corpuscular média não apresentaram alterações entre os tratamentos, em ambos os períodos. As proteínas totais aumentaram significativamente no plasma de tambaquis que receberam dietas com inclusão de 5 e 10% de silagem, avaliados após 45 dias de alimentação. Evidenciou-se que os grupos com inclusão de silagem na dieta não apresentaram alterações significativas nos parâmetros avaliados, assim não sendo prejudiciais à higidez do tambaqui. Portanto, o uso da silagem como suplemento alimentar durante o cultivo do tambaqui é uma alternativa sustentável para produtores, por promover a redução do descarte de resíduos de pescado e da agricultura.

Cost analysis of photobiomodulation in tibia fracture in the Brazilian public health system.

Managing tibial fractures requires substantial health resources, which costs the health system. This study aimed to describe the costs of photobiomodulation (PBM) with LEDs in the healing process of soft tissue lesions associated with tibial fracture compared to a placebo. Economic analysis was performed based on a randomized controlled clinical trial, with a simulation of the cost-effectiveness and incremental cost model. Adults (n = 27) hospitalized with tibia fracture awaiting definitive surgery were randomized into two distinct groups: the PBM Group (n = 13) and the Control Group with simulated phototherapy (n = 14). To simulate the cost-effectiveness and incremental cost model, the outcome was the evolution of wound resolution by the BATES-JENSEN scale and time of wound resolution in days. The total cost of treatment for the Control group was R$21,164.56, and a difference of R$7,527.10 more was observed when compared to the treatment of the PBM group. The proposed intervention did not present incremental cost since the difference in the costs to reduce measures between the groups was smaller for the PBM group. When analyzing the ICER (Incremental cost-effectiveness ratio), it would be possible to save R$3,500.98 with PBM and decrease by 2.15 points in the daily average on the BATES-JENSEN scale. It is concluded, therefore, that PBM can be a supportive therapy of clinical and economic interest in a hospital setting.

A Cost Analysis of Rethink the Strip: De-implementing a Low-value Practice in Primary Care.

BACKGROUND: Routine self-monitoring of blood glucose is a low-value practice that provides limited benefit for patients with non-insulin-treated type 2 diabetes mellitus. OBJECTIVES: We estimated the costs of Rethink the Strip (RTS), a multistrategy approach to the de-implementation of self-monitoring of blood glucose in primary care. RESEARCH DESIGN: RTS was conducted among 20 primary care clinics in North Carolina. We estimated the non-site-based and site-based costs of the 5 RTS strategies (practice facilitation, audit and feedback, provider champions, educational meetings, and educational materials) from the analytic perspective of an integrated health care system for 12 and 27-month time horizons. Material costs were tracked through project records, and personnel costs were assessed using activity-based costing. We used nationally based wage estimates. RESULTS: Total RTS costs equaled $68,941 for 12 months. Specifically, non-site-based costs comprised $16,560. Most non-site-based costs ($11,822) were from the foundational programming and coding updates to the electronic health record data to develop the audit and feedback reports. The non-site-based costs of educational meetings, practice facilitation, and educational materials were substantially lower, ranging between ~$400 and $1000. Total 12-month site-based costs equaled $2569 for a single clinic (or $52,381 for 20 clinics). Educational meetings were the most expensive strategy, averaging $1401 per clinic. The site-based costs for the 4 other implementation strategies were markedly lower, ranging between $51 for educational materials and $555 for practice facilitation per clinic. CONCLUSIONS: This study provides detailed cost information for implementation strategies used to support evidence-based programs in primary care clinics.

Local anesthesia versus saddle block for open hemorrhoidectomy: cost-analysis from a randomized, double blind controlled trial.

BACKGROUND: Despite the benefits attributed to the use of local anesthesia (LA) for open hemorrhoidectomy (OH) in developed countries, this technique is still not considered as the first line technique in low-income countries such as Uganda; therefore, we aimed at comparing the cost of OH under LA versus Saddle block among patients with 3rd or 4th degree hemorrhoids. METHODS: This trial was conducted from December 2021 to May 2022 among patients with primary uncomplicated 3rd or 4th degree hemorrhoids. The operating time, and direct costs in (US$) including medical and non-medical were recorded. We analysed the cost in the two groups (local anesthesia versus saddle block) using SPSS version 23.0. RESULTS: Findings of fifty-eight patients were analysed including 29 participants per group. There was a significant difference in operating time and cost among the two groups (p < 0.05). The mean operating time was 15.52 ± 5.34(SD) minutes versus 33.72 ± 11.54 min for OH under LA and SB respectively. The mean cost of OH under LA was 57.42 ± 8.90 US$ compared to 63.38 ± 12.77US$ in SB group. CONCLUSION: The use of local anesthesia for OH was found to have less operating time with high-cost effectiveness. Being affordable, local anesthesia can help to increase the turnover of patients who would otherwise wait for the availability of anesthesia provider. Policy makers should emphasize its applicability in low-income settings to help in the achievement of 2030 global surgery goals.

Testing the effectiveness of household fuel conservation strategies: Policy implications for increasing the affordability of exclusive clean cooking.

BACKGROUND: Exclusive clean fuel use is essential for realizing health and other benefits but is often unaffordable. Decreasing household-level fuel needs could make exclusive clean fuel use more affordable, but there is a lack of knowledge on the amount of fuel savings that could be achieved through fuel conservation behaviors relevant to rural settings in low- and middle-income countries. METHODS: Within a trial in Peru, we trained a random half of intervention participants, who had previously received a liquefied petroleum gas (LPG) stove and were purchasing their own fuel, on fuel conservation strategies. We measured the amount of fuel and mega joules (MJ) of energy consumed by all participants, including control participants who were receiving free fuel from the trial. We administered surveys on fuel conservation behaviors and assigned a score based on the number of behaviors performed. RESULTS: Intervention participants with the training had a slightly higher conservation score than those without (7.2 vs. 6.6 points; p = 0.07). Across all participants, average daily energy consumption decreased by 9.5 MJ for each 1-point increase in conservation score (p < 0.001). Among households who used exclusively LPG (n = 99), each 1-point increase in conservation score was associated with a 0.04 kg decrease in LPG consumption per household per day (p = 0.03). Using pressure cookers and heating water in the sun decreased energy use, while using clay pots and forgetting to close stove knobs increased energy use. CONCLUSION: Our findings suggest that a household could save 1.16 kg of LPG per month for each additional fuel conservation behavior, for a maximum potential savings of 8.1 kg per month. Fuel conservation messaging could be integrated into national household energy policies to increase the affordability of exclusive clean fuel use, and subsequently achieve the environmental and health benefits that could accompany such a transition.

Municipal emission pathways and economic performance toward net-zero emissions: A case study of Nakhon Ratchasima municipality, Thailand.

The transition to net-zero emissions (NZEs) in developing countries is challenging and requires the immediate adoption of comprehensive climate policy packages, strong collaboration among all sectors and stakeholders, and timely financial and technological assistance for developing economies. This research aims to analyze and evaluate the pathways to realize an NZE scheme at the municipality level. Nakhon Ratchasima (NR) Municipality, Thailand, is selected as the case study for this research. The Global Protocol for Community-Scale GHG Emission Inventories (GPC) is applied as the robust framework to assess the city's GHG emission profile. A mathematical forecasting model and the participatory multicriteria decision-making (MCDM) approach were adopted to support evidence-based local climate action planning based on four different scenarios: the business-as-usual (BAU), nationally determined contribution (NDC), carbon neutrality (CN), and NZE scenarios. The roles of stakeholders at the local community level across all sectors in mitigation actions and investment costs were investigated, and cost-effectiveness was evaluated to understand the economic performance of the adoption and implementation of local climate policy packages. The results indicate that by employing solely conventional technologies, a residential city that is also a hub for trade and land transportation will be unable to achieve its net-zero targets. It is imperative to seek additional low-carbon businesses and decarbonizing technologies that accompany substantial investments. According to the case of NR Municipality, the implementation costs to attain the NZE target by 2050 would range between 974.40 and 4.131.96 million USD. A pivotal driver of the municipal NZE pathway is the successful mobilization private sector investments to propel the transition toward climate-friendly technologies. Cost-effectiveness analysis significantly bolsters the municipality's transitional plan preparation, holistically encompassing economic, social, and environmental considerations. By preparing these aspects together, we ensure a smooth and equitable transition to net zero, avoid conflicts and economic harm and leave no one behind. This approach ensures a harmonious balance between a net-zero future, economic growth, and environmentally friendly living for all.

Road map for sustainable and effective carbon pricing: bridging the gap of realities and ambitions.

An increase in policy ambition is needed to close the gaps related to climate change mitigation and those required to meet the targets of Paris Agreement. This article examines the contemporary situation of carbon pricing and suggests how carbon costs would help countries adopt comprehensive climate policies. This paper explores the carbon pricing imitative across different regions and the associated issues and proposes how to format holistic, ambitious approaches for effective implementation of carbon pricing. The carbon taxes and emission trading programs are the primary tools for implementation costs. Carbon taxes, fuel taxes, subsidies for fossil energy, and emission trading systems (ETSs) all contribute to these costs. Different countries have adopted different approaches to adopt and mitigate the adverse effect of carbon emissions, but coordinated and integrated efforts are needed. This paper emphasizes the effective carbon pricing and integrating role of finance departments in climate policy; new synergies can be developed to boost government agencies' ability to implement climate policy. Governments may increase their involvement in carbon pricing beyond direct carbon pricing if they implement efficient carbon pricing. Governments, international organizations, and civil society can all play a role in pushing for effective carbon prices to encourage more ambitious targets. Furthermore, the article stresses the need for open communication and a proper understanding of carbon pricing potential to implement climate policy.

Potential Avoidable Costs of Low-Value Clinical Practices in Acute Injury Care in an Integrated Canadian Provincial Trauma System.

[Settlement of the surgical treatment of lipoedema]. / Abrechnung der chirurgischen Therapie des Lipödems.

The billing of lipoedema treatment in Germany has come to be heterogeneous. This is due to the decision of the Federal Joint Committee ("Gemeinsamer Bundesausschuss", G-BA) to acknowledge lipoedema stage III as a treatment to be paid by the statutory health insurance funds ("Gesetzliche Krankenversicherung", GKV) until the completion of the trial study "LipLeg" at the end of 2024. Based on this decision, inpatient and outpatient surgical treatment of stage III lipoedema can be billed to the GKV, while the reimbursement of costs for surgical treatment of the other two stages remains a case-by-case decision of the GKV and is currently often rejected. Therefore, treatment costs are often paid by patients themselves. The question of the correct settlement of lipoedema treatment repeatedly arises in the context of legal disputes, which, in turn, repeatedly faces experts and courts with a major challenge. In the following article, the Task Force Lipoedema of the German Society for Plastic, Reconstructive and Aesthetic Surgery presents an overview of the various billing modalities and presents a proposal for the correct billing of lipoedema within the framework of the German medical fee schedule ("Gebührenordnung für Ärzte", GOÄ).

Cost Analysis of a Culturally Appropriate, Community-Delivered Intervention to Increase Physical Activity.

PURPOSE: Understand the cost of delivering existing community-based, no cost to participant, aerobic dance and yoga classes in an underserved, racial and ethnic minority community in the Midwest. DESIGN: Pilot 4-month observational, descriptive, cost analysis of community fitness classes. SETTING: Community-wide, group-based, fitness classes online, and in parks and community centers in traditionally Black neighborhoods in Kansas City. PARTICIPANTS: Participants (N = 1428) were recruited from underserved, racial and ethnic minority areas of Kansas City, Missouri. INTERVENTION: Aerobic dance and yoga classes were provided free of charge to all residents of Kansas City, Missouri online and in-person. Each class was approximately 1 hour, with a warmup and cooldown. All classes were delivered by African American women. METHODS: Descriptive statistics of the costs for the program are presented. Cost per metabolic equivalents (MET) were calculated. Independent samples t-tests were conducted to examine differences between aerobic dance and yoga cost per MET. RESULTS: The total program costs were $10,759.88 USD, with 1428 participants attending 82 classes over the 4-month intervention. The cost per MET was $1.67, $1.11, and $0.74/MET-hour/session/attendee for low, moderate, and high-intensity aerobic dance, respectively, and $3.02/MET-hour/session/attendee for yoga. Aerobic dance had a significantly lower cost per MET than yoga (t = 13.6, P < .001, t = 47.6, P < .001, t = 92.8, P < .001, for low, moderate, and high-intensity, respectively). CONCLUSIONS: Delivering community-based, physical activity interventions in racial and ethnic minority communities is a potential way to increase physical activity. The costs of group-based fitness classes are similar to other physical activity interventions. Further research needs to be conducted on the costs to increase physical activity of traditionally underserved populations who suffer from higher rates of inactivity and comorbidities.
