Epidemiology, economic, and humanistic burden of hereditary angioedema: a systematic review.

BACKGROUND: This systematic study aims to assess the global epidemiologic, economic, and humanistic burden of illness associated with all types of hereditary angioedema. METHODS: A systematic search for articles reporting the epidemiologic, economic, and humanistic burden associated with patients with HAE was conducted using English and Chinese literature databases from the inception to May 23, 2022. The selected studies were assessed for their quality and risk of bias. The study was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses and registered with the International Prospective Register of Systematic Reviews (PROSPERO; CRD42022352377). RESULTS: In total, 65 articles that met the search inclusion criteria reported 10,310 patients with HAE, of whom 5861 were female patients. Altogether, 4312 patients (81%) and 479 patients (9%) had type 1 and type 2 HAE, respectively, whereas 422 patients (8%) had HAE-normal C1-INH. The overall prevalence of all types of HAE was between 0.13 and 1.6 cases per 100,000. The mean or median delay from the first onset of a symptom of HAE to confirmed diagnosis ranged from 3.9 to 26 years. The estimated risk of death from asphyxiation was 8.6% for patients with HAE. Hospitalization, medication, unnecessary surgeries, doctor visits, specialist services, and nursing costs are direct expenses that contribute to the growing economic burden. The indirect cost accounted mostly due to missing work ($3402/year) and loss of productivity ($5750/year). Furthermore, impairment of QoL as reported by patient-reported outcomes was observed. QoL measures identified depression, anxiety, and stress to be the most common symptoms for adult patients and children. CONCLUSION: This study highlights the importance of early diagnosis and the need for improving awareness among health care professionals to reduce the burden of HAE on patients and society.

Economic cost of management of glaucoma in public and private health facilities in the Tema metropolis in Ghana.

Objectives: This study sought to determine the economic cost of the management of glaucoma among patients seeking care in health facilities in Ghana. Design: A cross-sectional cost-of-illness (COI) study from the perspective of the patients was employed. Setting: The study was conducted in public and private eye care facilities in the Tema Metropolis of Ghana. Participants: About 180 randomly selected glaucoma patients seeking healthcare at two facilities participated in the study. Main outcome measure: Direct cost, including medical and non-medical costs, indirect cost, and intangible burden of management of glaucoma. Results: the cost per patient treated for glaucoma in both facilities was US$60.78 (95% CI: 18.66-107.80), with the cost in the public facilities being slightly higher (US$62.50) than the private facility (US$ 59.3). The largest cost burden in both facilities was from direct cost, which constituted about 94% of the overall cost. Medicines (42%) and laboratory and diagnostics (26%) were the major drivers of the direct cost. The overall cost within the study population was US$10,252.06. Patients paid out of pocket for the frequently used drug- Timolol, although expected to be covered under the National Health Insurance Scheme (NHIS). Patients, however, expressed moderate intangible burdens due to glaucoma. Conclusion: The cost of the management of glaucoma is high from the perspective of patients. The direct costs were high, with the main cost drivers being medicines, laboratory and diagnostics. It is recommended that the National Health Insurance Authority (NHIA) should consider payment for commonly used medications to minimize the burden on patients. Funding: None declared.

Reducing economic burden through split-shared care model for people living with uncontrolled type 2 diabetes and polypharmacy: a multi-center randomized controlled trial.

BACKGROUND: Interprofessional collaborative care such as a split-shared care model involving family physicians and community pharmacists can reduce the economic burden of diabetes management. This study aimed to evaluate the economic outcome of a split-shared care model between family physicians and community pharmacists within a pharmacy chain in managing people with uncontrolled type 2 diabetes and polypharmacy. METHOD: This was a multi-center, parallel arm, open label, randomized controlled trial comparing the direct and indirect economic outcomes of people who received collaborative care involving community pharmacists (intervention) versus those who received usual care without community pharmacist involvement (control). People with uncontrolled type 2 diabetes, defined as HbA1c > 7.0% and taking ≥ 5 chronic medications were included while people with missing baseline economic data (such as consultation costs, medication costs) were excluded. Direct medical costs were extracted from the institution's financial database while indirect costs were calculated from self-reported gross income and productivity loss, using Work Productivity Activity Impairment Global Health questionnaire. Separate generalized linear models with log link function and gamma distribution were used to analyze changes in direct and indirect medical costs. RESULTS: A total of 175 patients (intervention = 70, control = 105) completed the trial and were included for analysis. The mean age of the participants was 66.9 (9.2) years, with majority being male and Chinese. The direct medical costs were significantly lower in the intervention than the control group over 6 months (intervention: -US$70.51, control: -US$47.66, p < 0.001). Medication cost was the main driver in both groups. There were no significant changes in productivity loss and indirect costs in both groups. CONCLUSION: Implementation of split-shared visits with frontline community partners may reduce economic burden for patient with uncontrolled type 2 diabetes and polypharmacy.

How Much Does Dysphagia Cost? Understanding the Additional Costs of Dysphagia for New Zealand in Patients Hospitalised with Stroke.

INTRODUCTION: Dysphagia (i.e., disordered swallowing) is a consequence of stroke. Existing literature on the marginal cost of dysphagia after stroke is limited and ignores long-term impacts. Our aim was to determine the marginal 12-month cost attributable to dysphagia, including health-related quality of life (HRQoL) impacts, among patients hospitalised with stroke in New Zealand. METHODS: Secondary analysis of observational data from the REGIONS Care study, a national study from New Zealand of consecutively hospitalised patients with acute stroke between May 1, 2018, and October 30, 2018, including an outcome survey at 12 months among those who provided consent. Patients were identified as dysphagic if they received a swallow screen in hospital resulting in a speech language therapist review. Patients that required a nasogastric feeding tube in hospital were classified as "severe." Optimal linear propensity score matching was utilised to provide a group of patients to compare with stroke and dysphagia. All costs were converted to 2021NZD. RESULTS: Overall, of the 2,379 patients in the REGIONS cohort (51% male, median age: 78), 40% (944/2,379) were dysphagic (52% male, median age: 78), and 5% (111/2,379) were classified as severely dysphagic. Within 12 months of hospital discharge, dysphagia reduced HRQoL overall by 0.06 index points (95% CI: 0.028-0.100), and severe dysphagia by 0.12 index points (95% CI: 0.03-0.20). The estimated marginal 12-month cost attributable to stroke-related dysphagia was NZD 24,200 on average per patient. This estimate includes the additional hospitalisation costs (NZD 16,100), community rehabilitation services (NZD 570), hospital level aged residential care (NZD 4,030), and reduced HRQoL (NZD 3,470) over a 12-month period post-hospital discharge. The overall total marginal cost for those with severe dysphagia was NZD 34,000 per patient. CONCLUSION: We report cost estimates to 12 months from a national perspective on the additional costs and HRQoL outcomes of dysphagia for people hospitalised with stroke in New Zealand. Findings provide a novel contribution internationally since few prior studies have extended beyond the acute hospital phase of care. By quantifying the economic burden, we provide information to decision makers to improve dysphagia management strategies and ultimately enhance the overall HRQoL for people with stroke and dysphagia.

Financial and economic costs of healthcare-associated infections in Africa.

BACKGROUND: Healthcare-associated infections (HAIs) remain a global health challenge, and have elevated rates in Sub-Saharan Africa. HAIs impact patients and their families by causing illness, prolonged hospital stay, potential disability, excess costs and, sometimes, death. The costs of HAIs are increasing due to spreading antimicrobial resistance. A major risk factor for HAIs is lack of water, sanitation and hygiene (WASH); environmental cleaning and healthcare waste management. In Sub-Saharan Africa, these services are lacking in at least 50% of healthcare facilities. AIM: To estimate the costs associated with HAIs at national level in 14 countries in Sub-Saharan Africa. METHODS: Economic methodologies were employed to estimate the medical costs, productivity losses and value of premature death from HAIs, drawing on national statistics and published studies to populate the economic model. RESULTS: In 2022, the number of HAIs was estimated at 4.8 million, resulting in 500,000 deaths. Health-related economic losses amounted to US$13 billion per year, equivalent to 1.14% of combined gross domestic product and US$15.7 per capita. Healthcare costs were US$500 per HAI, and represented 5.6% of total health expenditure. The costs of providing basic WASH were US$0.91 per capita, which, if they reduced HAIs by 50%, would result in benefit-cost ratios of 1.6 (financial healthcare savings alone) and 8.6 (all economic benefits). CONCLUSION: HAIs have a major health and economic burden on African societies, and a significant proportion can be prevented. It is critical that health policy makers and practitioners dedicate policy space, resources and training to address HAIs.

The clinical role of remimazolam: Protocol for a scoping review.

BACKGROUND: Remimazolam, a novel benzodiazepine, shows promise as an alternative to traditional sedatives and hypnotic agents in procedural sedation and general anaesthesia. While preliminary research indicates potential advantages over conventional agents, such as faster onset, predictable duration, and improved safety profile, the extent and quality of existing evidence remain unclear. This scoping review aims to investigate the current clinical role of remimazolam and provide a broad and comprehensive overview. METHODS: The proposed review will adhere to the JBI methodology for scoping reviews and the Preferred Reporting Items for Systematic Review and Meta-Analysis for Scoping Reviews. A comprehensive search will be conducted across major peer-reviewed databases and grey literature will be sought. All studies involving individuals undergoing procedural sedation or general anaesthesia with remimazolam will be eligible. Data extraction will encompass trial and participant characteristics, intervention details, reported outcomes, comparative efficacy versus midazolam and propofol, patient and operator experience and economic costs. RESULTS: We will provide a descriptive summary supplemented by statistics, figures and tables where applicable. CONCLUSION: The outlined scoping review aims to assess the clinical use of remimazolam in procedural sedation and as the hypnotic component of general anaesthesia. The review will map the current body of evidence of remimazolam and identify knowledge gaps, contributing to understanding its clinical implications and guiding future research efforts in procedural sedation and general anaesthesia.

Economic Cost of Rehabilitation with Robotic and Virtual Reality Systems in People with Neurological Disorders: A Systematic Review.

Background: The prevalence of neurological disorders is increasing worldwide. In recent decades, the conventional rehabilitation for people with neurological disorders has been often reinforced with the use of technological devices (robots and virtual reality). The aim of this systematic review was to identify the evidence on the economic cost of rehabilitation with robotic and virtual reality devices for people with neurological disorders through a review of the scientific publications over the last 15 years. Methods: A systematic review was conducted on partial economic evaluations (cost description, cost analysis, description of costs and results) and complete (cost minimization, cost-effectiveness, cost utility and cost benefit) studies. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. The main data sources used were PubMed, Scopus and Web of Science (WOS). Studies published in English over the last 15 years were considered for inclusion in this review, regardless of the type of neurological disorder. The critical appraisal instrument from the Joanna Briggs Institute for economic evaluation and the Consolidated Health Economic Evaluation Reporting Standards (CHEERS) were used to analyse the methodological quality of all the included papers. Results: A total of 15 studies were included in this review. Ten papers were focused on robotics and five on virtual reality. Most of the studies were focused on people who experienced a stroke. The robotic device most frequently used in the papers included was InMotion® (Bionik Co., Watertown, MA, USA), and for those focused on virtual reality, all papers included used semi-immersive virtual reality systems, with commercial video game consoles (Nintendo Wii® (Nintendo Co., Ltd., Kyoto, Japan) and Kinect® (Microsoft Inc., Redmond, WA, USA)) being used the most. The included studies mainly presented cost minimization outcomes and a general description of costs per intervention, and there were disparities in terms of population, setting, device, protocol and the economic cost outcomes evaluated. Overall, the methodological quality of the included studies was of a moderate level. Conclusions: There is controversy about using robotics in people with neurological disorders in a rehabilitation context in terms of cost minimization, cost-effectiveness, cost utility and cost benefits. Semi-immersive virtual reality devices could involve savings (mainly derived from the low prices of the systems analysed and transportation services if they are applied through telerehabilitation programmes) compared to in-clinic interventions.

Short-term effects of air pollutants on hospital admissions for asthma among older adults: a multi-city time series study in Southwest, China.

Background: This study aimed to explore the relationship between air pollution and hospital admissions for asthma in older adults, and to further assess the health and economic burden of asthma admissions attributable to air pollution. Methods: We collected information on asthma cases in people over 65 years of age from nine cities in Sichuan province, as well as air pollution and meteorological data. The relationship between short-term air pollutant exposure and daily asthma hospitalizations was analyzed using the generalized additive model (GAM), and stratified by gender, age, and season. In addition, we assessed the economic burden of hospitalization for air pollution-related asthma in older adults using the cost of disease approach. Results: The single pollutant model showed that every 1 mg/m3 increase in CO was linked with an increase in daily hospitalizations for older adults with asthma, with relative risk values of 1.327 (95% CI: 1.116-1.577) at lag7. Each 10 µg/m3 increase in NO2, O3, PM10, PM2.5 and SO2, on asthma hospitalization, with relative risk values of 1.044 (95% CI: 1.011-1.078), 1.018 (95% CI: 1.002-1.034), 1.013 (95% CI: 1.004-1.022), 1.015 (95% CI: 1.003-1.028) and 1.13 (95% CI: 1.041-1.227), respectively. Stratified analysis shows that stronger associations between air pollution and asthma HAs among older adult in females, those aged 65-69 years, and in the warm season, although all of the differences between subgroups did not reach statistical significance. During the study period, the number of asthma hospitalizations attributable to PM2.5, PM10, and NO2 pollution was 764, 581 and 95, respectively, which resulted in a total economic cost of 6.222 million CNY, 4.73 million CNY and 0.776 million CNY, respectively. Conclusion: This study suggests that short-term exposure to air pollutants is positively associated with an increase in numbers of asthma of people over 65 years of age in Sichuan province, and short-term exposure to excessive PM and NO2 brings health and economic burden to individuals and society.

A Systematic Review of the Economic Burden of Diabetes in Eastern Mediterranean Region Countries.

Diabetes Mellitus (DM) is a highly prevalent non-communicable disease with high mortality and morbidity, which imposes a significant financial impact on individuals and the healthcare system. The identification of various cost components through cost of illness analysis could be helpful in health-care policymaking. The current systematic review aims to summarize the economic burden of DM in the Eastern Mediterranean Region (EMR) countries. The original studies published in the English language between January 2010 and June 2023 reported the cost of DM was identified by searching four different databases (Google Scholar, PubMed, Science Direct, and Cochrane Central). Two reviewers independently screened the search results and extracted the data according to a predefined format, whereas the third reviewer's opinion was sought to resolve any discrepancies. The costs of DM reported in the included studies were converted to USD dates reported in the studies. After the systematic search and screening process, only 10 articles from EMR countries met the eligibility criteria to be included in the study. There are substantial variations in the reported costs of DM and the methodologies used in the included studies. The mean annual cost per patient of DM (both direct and indirect cost) ranged from 555.20 USD to 1707.40 USD. The average annual direct cost ranged from 155.8 USD to 5200 USD and indirect cost ranged from 93.65 USD to 864.8 USD per patient. The studies included in the review obtained a median score of 8.65 (6.5 ─ 11.5) on the quality assessment tool based on Alison's checklist for evaluation of cost of illness studies. There is a significant economic burden associated with DM, which directly affects the patients and healthcare system. Future research should focus on refining cost estimation methodologies, improving the understanding of study findings, and making it easier to compare studies.

Ambient PM2.5 and productivity-adjusted life years lost in Brazil: a national population-based study.

Enormous health burden has been associated with air pollution and its effects continue to grow. However, the impact of air pollution on labour productivity at the population level is still unknown. This study assessed the association between premature death due to PM2.5 exposure and the loss of productivity-adjusted life years (PALYs), in Brazil. We applied a novel variant of the difference-in-difference (DID) approach to assess the association. Daily all-cause mortality data in Brazil were collected from 2000-2019. The PALYs lost increased by 5.11% (95% CI: 4.10-6.13%), for every 10 µg/m3 increase in the 2-day moving average of PM2.5. A total of 9,219,995 (95% CI: 7,491,634-10,921,141) PALYs lost and US$ 268.05 (95% CI: 217.82-317.50) billion economic costs were attributed to PM2.5 exposure, corresponding to 7.37% (95% CI: 5.99-8.73%) of the total PALYs lost due to premature death. This study also found that 5,005,306 PALYs could be avoided if the World Health Organization (WHO) air quality guideline (AQG) level was met. In conclusion, this study demonstrates that ambient PM2.5 exposure is associated with a considerable labour productivity burden relating to premature death in Brazil, while over half of the burden could be prevented if the WHO AQG was met. The findings highlight the need to reduce ambient PM2.5 levels and provide strong evidence for the development of strategies to mitigate the economic impacts of air pollution.

Overcoming public resistance to carbon taxes: A cost-efficient solution built on a pre-existing reward-based climate policy.

A carbon tax is effective at curbing carbon emissions, but it is met with low public support due to its high personal cost. Investigations have been conducted to reform carbon tax design to ease the burden on individuals by providing economic compensation, but the cost for governments is high. We propose a new cost-efficient solution by introducing people to a pre-existing reward-based climate policy to create a sense of economic compensation. Across three experiments, we show that the presence of a pre-existing reward-based climate policy increases participants' support for a carbon tax, especially when the innate connection between the two policies is made salient and people regard the reward as compensation for the tax. In contrast, if people are distracted from sensing this interrelationship, support for the tax does not differ from when it is introduced alone. Applicability of this approach was tested under different conditions where the pressure to reduce carbon emission is either high or low.

Healthcare provider cost of antimicrobial resistance in two teaching hospitals in Ghana.

Understanding the healthcare provider costs of antimicrobial resistance (AMR) in lower-middle-income countries would motivate healthcare facilities to prioritize reducing the AMR burden. This study evaluates the extra length of stay and the associated healthcare provider costs due to AMR to estimate the potential economic benefits of AMR prevention strategies. We combined data from a parallel cohort study with administrative data from the participating hospitals. The parallel cohort study prospectively matched a cohort of patients with bloodstream infections caused by third-generation cephalosporin-resistant enterobacteria and methicillin-resistant Staphylococcus aureus (AMR cohort) with two control arms: patients infected with similar susceptible bacteria and a cohort of uninfected controls. Data collection took place from June to December 2021. We calculated the cost using aggregated micro-costing and step-down costing approaches and converted costs into purchasing power parity in international US dollars, adjusting for surviving patients, bacterial species and cost centres. We found that the AMR cohort spent a mean of 4.2 extra days (95% CI: 3.7-4.7) at Hospital 1 and 5.5 extra days (95% CI: 5.1-5.9) at Hospital 2 compared with the susceptible cohort. This corresponds to an estimated mean extra cost of $823 (95% CI: 812-863) and $946 (95% CI: US$929-US$964) per admission, respectively. For both hospitals, the estimated mean annual extra cost attributable to AMR was approximately US$650 000. The cost varies by organism and type of resistance expressed. The result calls for prioritization of interventions to mitigate the spread of AMR in Ghana.

Revision surgery versus biologic treatment with omalizumab in recurrent chronic rhinosinusitis with nasal polyps: An analysis of cost-utility and clinical outcomes.

Background: Both revision surgery and omalizumab are recommended therapies for the treatment of recurrent chronic rhinosinusitis with nasal polyps (CRSwNP) and can improve patients' clinical symptoms and quality of life (QoL). The aim of this study was to compare the improvement in sinus-related symptoms, QoL, economic cost, and duration cost between treatment with revision-surgery and treatment with omalizumab. Methods: This was a prospective study of patients with recurrent CRSwNP. All patients were asked to complete a 22-item sino-nasal outcome test (SNOT-22), a visual analog scale (VAS), and a 36-item short-form (SF-36) questionnaire at baseline and 6 months after the treatments. Patients were required to document economic costs and duration costs within 6 months and report them at each visit. Results: A total of 44 patients who received the treatment of revision surgery or omalizumab were enrolled in this study. After six months of treatment, the improvements in total SNOT-22 and SF-36 in 8 domains were not different between the 2 treatments. The improvements in rhinologic symptoms, extranasal rhinologic symptoms, and ear/facial symptoms according to the SNOT-22 (P value = 0.0288, 0.0016, and 0.0347, respectively) and the improvements in nasal congestion, loss of smell, and overall symptoms assessed by the VAS (P value = 0.0057, 0.0206, and 0.0122, respectively) were better in the revision surgery group than in the omalizumab group. The economic cost and the total duration cost were obviously lower in the omalizumab group (¥18836 and 1 day) than in the revision surgery group (¥29824 and 23 days). Conclusions: Both revision surgery and omalizumab treatments can improve the clinical symptoms and QoL of patients with recurrent CRSwNP. Patients who underwent revision surgery experienced better improvement in sinus-related symptoms. However, omalizumab treatment clearly showed a benefit in terms of economic cost and duration cost of disease-related care.

Thermodynamic and thermo-economic analyses of a coupled heat-pump system for low-grade exhaust-air heat exchange in mines.

Combining mine exhaust waste heat with existing heat pump technology is a promising technical route to realise the efficient extraction and scientific use of low-grade waste heat resources in mines and to solve the problem of insufficient heat supply in remote mining areas. This study proposes a new type of mine-exhaust-air heat exchange coupled with heat-pump waste-heat-utilisation system based on deep enthalpy heat extraction. Using a mining area in Northwest China as a representative case, this study establishes a systematic exergy analytical model and a thermo-economic model. Through an in-depth analysis of the different evaporation temperatures and condensing temperatures, the system's energy efficiency ratio (COP) reaches its optimal performance, with the total exergy efficiency surpassing 90%. The minimum efficiency of the subsystem return air heat exchanger is 35%. The unit thermal costs of the mine exhaust air waste heat utilisation system and a conventional coal-fired boiler system are 0.1291 and 0.1573 million RMB/kW·h, respectively. This is a thermal economics cost saving of 21%. The studied system demonstrates great economic viability and the potential for energy saving throughout its life cycle.

The Short-Term Effects and Burden of Ambient Air Pollution on Hospitalization for Type 2 Diabetes: Time-Stratified Case-Crossover Evidence From Sichuan, China.

Type 2 diabetes mellitus (T2DM), a complicated metabolic disease, might be developed or exacerbated by air pollution, resulting in economic and health burden to patients. So far, limited studies have estimated associations between short-term exposure to air pollution and disease burden of T2DM in China. Hence, we aimed to estimate the associations and burden of ambient air pollutants (NO2, PM10, PM2.5, SO2, and CO) on hospital admissions (HAs) for T2DM using a time-stratified case-crossover design. Data on HAs for T2DM during 2017-2019 were collected from hospital electronic health records in nine cities in Sichuan Province using conditional poisson regression. Totally, 92,381 T2DM hospitalizations were recorded. There were significant short-term effects of NO2, PM10, PM2.5, SO2 and CO on HAs for T2DM. A 10 µg/m3 increment of NO2, PM10, PM2.5, SO2 and CO as linked with a 3.39% (95% CI: 2.26%, 4.54%), 0.33% (95% CI: 0.04%, 0.62%), 0.76% (95% CI: 0.35%, 1.16%), 12.68% (95% CI: 8.14%, 17.42%) and 79.00% (95% CI: 39.81%, 129.18%) increase in HAs for T2DM at lag 6. Stratified analyses modified by age, sex, and season showed old (≥65 years) and female patients linked with higher impacts. Using WHO's air quality guidelines of NO2, PM10, PM2.5, and CO as the reference, the attributable number of T2DM HAs exceeding these pollutants exposures were 786, 323, 793, and 2,127 during 2017-2019. Besides, the total medical costs of 25.83, 10.54, 30.74, and 67.78 million China Yuan were attributed to NO2, PM10, PM2.5, and CO. In conclusion, short-term exposures to air pollutants were associated with higher risks of HAs for T2DM.

Comparative assessment of Chinese mitten crab aquaculture in China: Spatiotemporal changes and trade-offs.

The increasing human demand for high-quality animal protein has provided impetus for the development of aquaculture. Chinese mitten crab (Eriocheir sinensis) is a catadromous species rapidly being cultured in China but scientific literature documenting its life cycle environmental and economic consequences remains scarce. This study aims to address this gap by examining the spatio-temporal evolution of crab aquaculture in China since the 2000s and evaluating the environmental and economic characteristics along its life-cycle stages: megalopa, juvenile crab, and adult crab cultivation. The geostatistical analysis shows a more dispersed pattern of crab aquaculture nationally as crab grows, with coastal provinces that have brackish water for megalopa cultivation but wider spatial coverage for juvenile and adult crab cultivation. Our findings reveal that the production of 1 ton of live-weight crab results in 7.65 ton of CO2 equivalent of greenhouse gas emissions, surpassing previous estimates for finfish fish production by approximately 50%. Most environmental pressures occur during the adult crab cultivation stage, with significant contributions from upstream processes such as electricity and feed production. By comparing between different production systems, our study shows that crab aquaculture in lake systems performs better than pond systems in terms of most global environmental impact categories and economic considerations. This work contributes to the existing literature by elucidating the spatio-temporal changes of crab aquaculture boom in China and constructing a representative life cycle data pool that broadens the benchmark knowledge on its environmental and economic characteristics. We highlight the trade-offs between environmental and economic performance as well as the balance between global and local environmental impacts to promote sustainable growth in the aquaculture industry.

The multifaceted consequences and economic costs of child anxiety problems: A systematic review and meta-analysis.

Background: Over a quarter of people have an anxiety disorder at some point in their life, with many first experiencing difficulties during childhood or adolescence. Despite this, gaps still exist in the current evidence base of the multiple consequences of childhood anxiety problems and their costs. Methods: A systematic review of Medline, PsycINFO, EconLit and the National Health Service Economic Evaluation Database was conducted for longitudinal and economic studies reporting on the association between childhood anxiety problems and at least one individual-, family- or societal-level outcome or cost. All studies were synthesised narratively. For longitudinal studies, 'effect direction' was used as a common metric, with random effects meta-analysis undertaken where possible. Results: Eighty-three studies met inclusion criteria and were synthesised narratively. We identified 788 separate analyses from the longitudinal studies, which we grouped into 15 overarching outcome domains. Thirteen of the studies were incorporated into 13 meta-analyses, which indicated that childhood anxiety disorders were associated with future anxiety, mood, behaviour and substance disorders. Narrative synthesis also suggested associations between anxiety problems and worse physical health, behaviour, self-harm, eating, relationship, educational, health care, employment, and financial outcomes. 'Effect direction' was conflicting in some domains due to a sparse evidence base. Higher economic costs were identified for the child, their families, healthcare providers and wider society, although evidence was limited and only covered short follow-up periods, up to a maximum of 2 years. Total annual societal costs per anxious child were up to £4040 (2021 GBP). Conclusions: Childhood anxiety problems are associated with impaired outcomes in numerous domains, and considerable economic costs, which highlight the need for cost-effective interventions and policies to tackle them. More economic evidence is needed to inform models of the long-term, economic-related, consequences of childhood anxiety problems.

The humanistic and economic burden of work-related musculoskeletal pain: a cross-sectional survey of workers in the United Kingdom.

OBJECTIVE: The aim of this study was to evaluate the impact of work-related musculoskeletal (MSK) lower body pain on health-related quality of life (HRQoL) and work productivity in a large sample of workers in the United Kingdom, as well as evaluating the potential economic impact of MSK pain. METHODS: Participants with self-reported work-related MSK pain were recruited from an online panel maintained by a third party (Qualtrics LLC). Participants completed three validated instruments online: the Brief Pain Inventory (BPI), the Assessment of Quality of Life Instrument (AQoL-4D), and the 6-item Work Productivity and Activity Impairment Questionnaire (WPAI). Sociodemographic details, work patterns and healthcare resource utilisation were also reported. One-way analysis of variance (ANOVA) and t-tests were used to explore differences between variables. Linear regression was applied to determine the impact of work-related MSK pain on HRQoL. RESULTS: All 1035 recruited participants completed the survey (57.4% female; mean age 43.4 years). Participants reported spending all (25.2%) or most (53%) of their time at work on their feet. Mean pain severity was 4.63 (standard deviation: 2.07); mean pain interference was 4.37 (2.49). There was a linear relationship between length of shift, time on feet and pain. Mean AQoL-4D scores were 0.609 (0.254). A mean of 4.12 h was lost per week due to pain. Absenteeism (last 7 days) was 9.5% (20.7%), and presenteeism 33.3% (24.9%). An average 1.55 visits were made to family practitioners (total cost: £19,866) and 1 hospital visit (£37,320) due to work-related MSK pain. CONCLUSION: This study demonstrated that work-related lower body pain has a significant impact in terms of individual HRQoL and as an economic societal burden.

Energy behaviour and economic analysis of a photovoltaic-thermal (PV/T) collector coupled with a reverse osmosis (RO) desalination unit in Tunisian climatic conditions: a feasibility study.

Water scarcity affects about one billion people in the world. Around two billion people could be living in water-stressed areas by 2050. For this reason, the desalination is always evolving due to the importance of the water resources found in the seas and brackish water. As these systems are generally energy intensive, the use of a renewable energy source is among the most appropriate solution. In this paper, both experimental and numerical investigations have been conducted to evaluate the performances and the economic viability of a photovoltaic-thermal collector intended to supply a reverse osmosis (RO) unit. Experimental study is based on the input-output and dynamic system testing (DST) according to ISO 9459-5 standard method and computations use the energy and mass balances of the PV/T collector and the RO plant. Results of DST testing showed that the loss coefficient of the PV/T, the tank loss coefficient and the total tank heat capacity are 10.46 W.m-2.K-1, 1.596 W.K-1 and 388 MJ.K-1, respectively. The ability to couple the RO technology to PV/T systems has been demonstrated. The complete system has been simulated for a water salinity of 10,000 ppm and climatic data of Borj-Cedria (Tunisia) site (longitude 10° 25' 41″ E and latitude 36° 43' 04″ N). Numerical investigations showed that the electricity needs of a small off-grid desalination unit could be met by using a 6.48 m2 PV/T panel surface area. In this case, the purified water produced has a salinity of 1500 ppm and the flow rate is 24,000 l/day. For a grid connected site, the produced and auxiliary powers are found to be equal to 54% and 21%, respectively. Moreover, the economic cost of adding a PV/T system into an existing RO unit has been evaluated and the results showed that the payback period is 6 years.

"The Little Money I Get Is Used to Buy Drugs": A Qualitative Exploration of the Economic Cost of Intimate Partner Violence for Female Survivors in Ghana.

Empirical research confirms the economic costs of intimate partner violence (IPV) for women. Yet, scholarship on this topic is lacking in Ghana, where IPV against women is commonplace. We used in-depth interviews with 15 female survivors of IPV in the Eastern Region to examine the economic costs of IPV for women. Findings showed that the economic costs were both direct and indirect. Direct costs included out-of-pocket payments for medical and nonmedical services, while indirect costs included diminished work abilities, increased absenteeism from work, and lowered work productivity. Ghanaian policymakers must enforce and strengthen policies to prevent violence against women.
