UNASSIGNED: To evaluate the cost-effectiveness of budesonide/formoterol reliever and maintenance therapy compared with salmeterol/fluticasone plus salbutamol as reliever therapy for asthma patients ≥12 years from the societal perspective in China.
UNASSIGNED: A Markov model was developed with three health states (non-exacerbation, exacerbation, and death) with a lifetime horizon. The exacerbation rates were obtained from a prospective cohort study conducted in Chinese asthma patients. Healthcare resources utilization data were estimated based on current clinical asthma management guidelines. Asthma-related mortality, cost input and utility values were derived from public database and literature. Model robustness was assessed with one-way sensitivity and probabilistic sensitivity analyses.
UNASSIGNED: Compared with salmeterol/fluticasone plus salbutamol, budesonide/formoterol reliever and maintenance therapy led to fewer exacerbation events (13.6 vs. 15.9) and 0.0077 quality-adjusted life years (QALY) gain at an additional cost of ¥196.38 over lifetime. The base case incremental cost-effectiveness ratio (ICER) was ¥25,409.98 per QALY gained. The variables that had most impact on the model output included drug costs and medication adherence. At a willingness-to-pay threshold of ¥257,094/QALY (3 times of gross domestic product per capita in China in 2022), the probability of budesonide/formoterol maintenance and reliever therapy being cost-effective versus salmeterol/fluticasone plus as-needed salbutamol was 83.00%.
UNASSIGNED: From the societal perspective, budesonide/formoterol reliever and maintenance therapy is likely to be a cost-effective option compared with salmeterol/fluticasone plus as-needed salbutamol for Chinese asthma patients ≥12 years.

UNASSIGNED: Implantable cardioverter defibrillator (ICDs) for primary prevention (PP) of sudden cardiac arrest (SCA) is underutilized in developing countries. The Improve SCA study has identified a subset of 1.5 primary prevention (1.5PP) patients with a higher risk of SCA and a significant mortality benefit from ICD therapy. From the perspective of China\'s healthcare system, we evaluated the cost-effectiveness of ICD therapy vs. no ICD therapy among 1.5PP patients with a view to informing clinical and policy decisions.
UNASSIGNED: A published Markov model was adjusted and verified to simulate the course of the disease and describe different health states of 1.5PP patients. The patient characteristics, mortality, utility and complication estimates were obtained from the Improve SCA study and other literature. Cost inputs were sourced from government tender prices, medical service prices and clinical experts\' surveys in 9 Chinese public hospitals. For both ICD and no ICD therapy, the total medical costs and quality-adjusted life-years (QALYs) were modelled over a lifetime horizon and the incremental cost-effectiveness ratio (ICER) was calculated. Deterministic and probabilistic sensitivity analyses were performed to assess the uncertainty of the model parameters. We used the willingness-to-pay (WTP) threshold recommended by China Guidelines for Pharmacoeconomic Evaluations, one to three times China\'s GDP per capita (CNY85,698-CNY257,094) in 2022 Chinese Yuan.
UNASSIGNED: The incremental cost effectiveness ratio (ICER) of ICD therapy compared to no ICD therapy is 139,652 CNY/QALY, which is about 1-2 times China\'s GDP per capita. The probability that ICD therapy is cost effective was 92.1%. Results from sensitivity analysis supported the findings of the base case.
UNASSIGNED: ICD therapy compared to no ICD therapy is cost-effective for the 1.5PP patients in China.

UNASSIGNED: This study assessed the treatment patterns, healthcare resource utilization (HRU), costs, and annual prevalence and incidence of metastatic hormone-sensitive prostate cancer (mHSPC) and nonmetastatic castration-resistant prostate cancer (nmCRPC) in China.
UNASSIGNED: A retrospective study was conducted using electronic medical records (EMR) of patients with prostate cancer from three tertiary-care hospitals in China between January 2014 and March 2021. Descriptive statistics were used to analyze study outcomes.
UNASSIGNED: In total, 1086 patients with mHSPC and 679 patients with nmCRPC were included. From 2015 to 2020, the annual percentage of prevalent and incident cases of mHSPC decreased from 22.4% to 20.0% and 11.1% to 6.9%, respectively; for nmCRPC, these increased from 3.8% to 13.6% and 3.3% to 8.4%. Androgen-deprivation therapy and first-generation antiandrogens (bicalutamide or flutamide) were the most frequently prescribed prostate cancer-related medications at baseline and follow-up in patients with mHSPC. Bicalutamide was the most frequently prescribed prostate cancer-related medication during follow-up in patients with nmCRPC. For mHSPC, inpatient admission costs were the highest, with the median (interquartile range) costs per person-month being USD 403.00 (USD 85.50-1226.20), whereas outpatient visit costs were the highest for nmCRPC (USD 372.60 [USD 139.50-818.50]).
UNASSIGNED: EMR-based study design did not capture treatment patterns, HRU and associated costs, and healthcare encounters that occurred outside of participating hospitals, which could have led to underestimation of the true disease burden.
UNASSIGNED: A contrasting trend of a decline in the prevalence and incidence of mHSPC and an increase in these for nmCRPC was observed between 2015 and 2020 in China. Androgen-deprivation therapy and first-generation antiandrogens were the most frequently prescribed prostate cancer-related medications. Healthcare resource utilization was driven by inpatient costs in mHSPC and outpatient costs in nmCRPC.

UNASSIGNED: Evaluate the cost utility of menopausal hormone therapy for women in China.
UNASSIGNED: A bespoke Markov cost utility model was developed to evaluate a cohort of symptomatic perimenopausal women (>45 years) with intact uterus in China in accordance with China\'s Pharmacoeconomic guideline. Short (5-year) and long (10-year) treatment durations were evaluated over a lifetime model time horizon with 12-month cycle duration. Societal and healthcare payer perspectives were evaluated in the context of a primary care provider/prescriber, outpatient setting with inpatient care for patients with chronic conditions. Disease risk and mortality parameters were derived from focused literature searches, and China Diagnosis-related Group cost data was included. Comprehensive scenario, univariate and probabilistic sensitivity analysis were undertaken along with independent validation. This is the first model to include MHT-related disease risks.
UNASSIGNED: According to base case results, the total cost for MHT was 22,516$ (150,106¥) and total quality adjusted life years 12.32 versus total cost of no MHT 30,824$ (205,495¥) and total quality adjusted life years 11.16 resulting in a dominant incremental cost effectiveness ratio of -7,184$ (-47,898¥) per QALY. Results hold true over a range of univariate deterministic sensitivity and scenario analyses. Probabilistic analysis showed a 91% probability of being cost effective at a willingness to pay threshold of three times Gross Domestic Product per capita in China.
UNASSIGNED: Contingent on the structure and assumptions of the model, combination of estradiol plus dydrogesterone MHT is potentially cost saving in symptomatic women over the age of 45 years in China.
Menopausal hormone therapy is publicly funded in many countries to alleviate symptoms of menopause; however, uptake has been comparatively slow in China. This has implications for the estimated 168 million menopausal-aged women. This analysis is the first to evaluate the cost effectiveness of menopausal hormone therapy in China using best practice principles and incorporating longer term disease risks. Menopausal hormone therapy is potentially cost saving in the context of China.

BACKGROUND: Mediterranean diets (MedDiets) are linked to substantial health benefits. However, there is also growing evidence that the intensification of food production over the last 60 years has resulted in nutritionally relevant changes in the composition of foods that may augment the health benefits of MedDiets.
OBJECTIVE: To synthesize, summarize, and critically evaluate the currently available evidence for changes in food composition resulting from agricultural intensification practices and their potential impact on the health benefits of MedDiets.
METHODS: We summarized/synthesized information from (i) systematic literature reviews/meta-analyses and more recently published articles on composition differences between conventional and organic foods, (ii) desk studies which compared food composition data from before and after agricultural intensification, (iii) recent retail and farm surveys and/or factorial field experiments that identified specific agronomic practices responsible for nutritionally relevant changes in food composition, and (iv) a recent systematic literature review and a small number of subsequently published observational and dietary intervention studies that investigated the potential health impacts of changes in food composition resulting from agricultural intensification.
CONCLUSIONS: There has been growing evidence that the intensification of food production has resulted in (i) lower concentrations of nutritionally desirable compounds (e.g., phenolics, certain vitamins, mineral micronutrients including Se, Zn, and omega-3 fatty acids, α-tocopherol) and/or (ii) higher concentrations of nutritionally undesirable or toxic compounds (pesticide residues, cadmium, omega-6 fatty acids) in many of the foods (including wholegrain cereals, fruit and vegetables, olive oil, dairy products and meat from small ruminants, and fish) that are thought to contribute to the health benefits associated with MedDiets. The evidence for negative health impacts of consuming foods from intensified conventional production systems has also increased but is still limited and based primarily on evidence from observational studies. Limitations and gaps in the current evidence base are discussed. Conclusions: There is now substantial evidence that the intensification of agricultural food production has resulted in a decline in the nutritional quality of many of the foods that are recognized to contribute to the positive health impacts associated with adhering to traditional MedDiets. Further research is needed to quantify to what extent this decline augments the positive health impacts of adhering to a traditional MedDiet.

UNASSIGNED: To assess the economic burden of different chemotherapies for lung cancer patients and influencing factors in China.
UNASSIGNED: The economic burden of lung cancer, including direct, indirect and intangible costs was measured within three months after diagnosis and treatment. Direct cost included the cost of hospitalization, outpatient visits, out-of-pocket drug purchases, costs of transportation, accommodation and meal expenses while seeking treatments in hospitals. Cost information was attained from questionnaire and patients\' medical record. Indirect cost was measured by the patients\' and their caregivers\' productive days lost due to outpatient visits and hospitalization for lung cancer treatment. Intangible cost was obtained through the willingness-to-pay method from a questionnaire completed by the patient.
UNASSIGNED: Among the total cost of CNY71,401.92, direct cost, indirect cost and intangible cost constituted 89.02%, 4.29%, and 6.69% respectively. Educational level, occupation, family income, lung cancer classification, and the city of residence significantly influenced the total cost.
UNASSIGNED: Limitations in our study included: First, our follow-up period of three months was relatively short compared to the whole survival period of lung cancer patients. Second, the sample size of the chemotherapy combined with targeted therapy group was not large enough, and the cost data obtained would need confirmation in future studies. Third, participants came from only two localities, which may somewhat limit the representativeness of the study results for the whole of China.
UNASSIGNED: The economic burden of lung cancer treatment mainly came from the cost of the drugs. Patients taking chemotherapy had significantly higher cost compared to patients using targeted therapy. The cost was generally higher for those with higher educational level, those with higher family income, and those living in an economically more developed city. Patients with NSCLC had higher cost compared to patients with SCLC.
In China, lung cancer is the leading cause of cancer-related deaths and imparts a heavy economic burden. Most lung cancer patients are treated with chemotherapeutic and/of targeted agents because they are usually diagnosed at an advanced stage (IIIB or IV). The use of targeted therapy has achieved high response rates, longer overall survival, and longer progression-free survival compared with conventional chemotherapies. Adverse reactions with targeted therapeutic agents are usually mild compared with conventional chemotherapy. However, targeted drugs for lung cancer are usually more expensive than conventional chemotherapeutic drugs. It should be noted that the adverse effects and toxicities caused by chemotherapeutic drugs are generally more serious compared to targeted drugs; therefore, a number of measures are needed to prevent or relieve these reactions clinically. This can increase the financial burden of lung cancer treatment. Does these two treatments have a different cost? Our results showed that educational level, occupation, family income, classification of lung cancer, and the city of residence significantly influenced the total cost. Patients taking chemotherapy had significantly higher cost compared to patients using targeted therapy. This result suggests that targeted therapy for lung cancer is a better choice than chemotherapy.

UNASSIGNED: To compare cost offsets and contributing factors (false-negative rates and confirmatory imaging requirements, potentially leading to longer waiting times for diagnosis) as well as long-term cost effectiveness associated with the diagnostic and treatment pathways for colorectal cancer liver metastases (CRCLM) in the US, Japan, and China according to initial imaging modality used. Gadoxetate disodium (ethoxylbenzyl-diethylenetriaminepentaacetic acid)-enhanced magnetic resonance imaging (EOB-MRI) was compared to multidetector computed tomography (MDCT), extracellular contrast media enhanced-MRI (ECCM-MRI) (the US and China only) and contrast-enhanced ultrasound (CEUS).
UNASSIGNED: Decision tree models were developed to simulate the clinical pathway, from first diagnostic test to initial treatment decision, based on local clinical guidelines and validated by experts. Input data were derived from the literature (up to 31st December 2020) as well as from interviews with local experts. A Markov model extension was built to evaluate the number of false-negative patients and associated costs, over a lifetime horizon.
UNASSIGNED: The decision-tree models showed that, increasing proportionate use of initial EOB-MRI resulted in a cost-offset per patient (excluding false-negative patients) in all countries (USD 201 for the US, JPY 6,284 for Japan and CNY 446 for China) driven by reductions in follow-on diagnostic procedures and unnecessary treatment. The use of EOB-MRI was also associated with a shorter average waiting time to a final diagnosis and treatment decision compared to MDCT, ECCM-MRI and CEUS. The Markov model showed that with an increase in EOB-MRI use, there are fewer false-negative diagnoses over a lifetime horizon. In all three countries, the incremental cost-effectivenes ratio (ICER) was below standard willingness-to-pay thresholds.
UNASSIGNED: The findings of these models demonstrate that use of EOB-MRI early in the diagnostic pathway for CRCLM results in short-term cost savings, as well as being cost effective in the long term.

UNASSIGNED: Extraintestinal Pathogenic Escherichia coli (ExPEC) is a leading cause of invasive disease, including bacteremia and sepsis. Invasive ExPEC disease (IED) has the potential to complicate the clinical treatment of other conditions and is associated with an increased mortality, hospitalization, and worse outcomes. Older adults and individuals with comorbid conditions are at higher risk of IED. ExPEC is of particular concern in the Asia Pacific region due to aging populations and rising antimicrobial resistance.
UNASSIGNED: This study aimed to synthesize most recent data on the epidemiology, clinical and economic burden of IED in the elderly/high risk populations in China, Japan, South Korea, Taiwan, and Australia.
UNASSIGNED: A targeted literature review was conducted using Embase, Medline, as well as local scientific databases. We included studies published in English and local languages published from January 1, 2010 to October 7, 2020 that were relevant to the research objectives. Studies were narratively synthesized.
UNASSIGNED: A total of 1,047 studies were identified and 34 of them were included in this review. ExPEC accounted for 46.0% (1,238/2,692) of bacteria-related invasive diseases in patients aged above 60 years in South Korea, followed by China (44.4% (284/640)), Taiwan (39.0% (1,244/3,194)), and Japan (18.1% (581/3,206)), while Australia reported ExPEC out of all pathogens (54.7% (4,006/7,330)) in general adults. Comorbidities such as diabetes or cancer were common in these patients. Studies reported increases in length-of-stay, and in-hospital 30-day all-cause mortality related to ExPEC associated bacteremia was between 9% to 12%. From a cost perspective, a 3-fold increase in sepsis-associated cost was reported in South Korea between 2005 and 2012. In Australia, antimicrobial resistance contributed to an additional cost of AUD $5.8 million per year (95% uncertainty interval [UI], $2.2-$11.2 million) in the treatment of bloodstream infections (BSIs).
UNASSIGNED: ExPEC was a major cause of blood stream infection across China, Japan, South Korea, Taiwan, and Australia. Both the clinical and economic burden associated to ExPEC infections as well as the antimicrobial resistance observed in the elderly call for preventive and curative actions in these regions.
Extraintestinal Pathogenic Escherichia coli (ExPEC) is a leading cause of invasive disease, including bacteremia and sepsis.A targeted literature review included the most recent data from 34 published studies on the epidemiology and clinical and economic burden of IED in the elderly/high risk populations in China, Japan, South Korea, Taiwan, and Australia.ExPEC accounted for 46.0% (1,238/2,692) of bacteria-related invasive diseases in patients aged above 60 years in South Korea, followed by China (44.4% (284/640)), Taiwan (39.0% (1,244/3,194)), and Japan (18.1% (581/3,206)), while Australia reported ExPEC out of all pathogens (54.7% (4,006/7,330)) in general adults. Studies reported increases in length-of-stay and in-hospital 30-day all-cause between 9% to 12%. These factors, along with antimicrobial resistance observed in the elderly, call for preventive and curative actions in these regions.Data for costs associated with ExPEC induced BSI or sepsis in this region are limited, but evidence shows increasing expenditures.

The purpose of this study was to assess the effects of butylphthalide on cognitive deficiencies following sleep deprivation (SD).
The influence of butylphthalide on cognitive function changes in SD-induced mice was evaluated. Nissl staining and HE staining were used to analyze the morphology changes of the hippocampal formation. The changes in cognitive function of SD-induced mice were detected by the Morris water maze. Inflammatory factors, apoptosis, and signal pathway-related proteins in the mice hippocampus were detected.
SD increased escape latency and path length for mice to reach the hidden platform, decreased the time and range of activity in the target area, and reduced the number and time for traversing the target area. Butylphthalide significantly improved the cognitive decline of SD-induced spatial exploration and learning/memory ability. Butylphthalide also decreased the degeneration of hippocampal neurone, neuronal apoptosis, and inflammatory factors in hippocampus tissue. In addition, butylphthalide activated the nuclear factor erythroid 2-related factor (Nrf2)/heme oxygenase 1 (HO-1) pathway.
Butylphthalide alleviated SD-induced cognitive decline, neuronal apoptosis, and inflammation by activating Nrf2/HO-1 pathway. We suggested that butylphthalide may be a prospective candidate for the alleviation of cognitive deficit induced by SD.

UNASSIGNED: To compare relative costs associated with the diagnostic pathways for hepatocellular carcinoma (HCC) in the US and China according to the initial imaging modality used. Gadoxetate disodium (ethoxylbenzyl-diethylenetriaminepentaacetic acid)-enhanced magnetic resonance imaging (EOB-MRI) was compared to contrast-enhanced multidetector computed tomography (MDCT), extracellular contrast media enhanced-MRI (ECCM-MRI) and contrast-enhanced ultrasound (CEUS).
UNASSIGNED: Decision tree models were developed to simulate the clinical pathway, based on local clinical guidelines, and validated by experts. Input data were derived from the literature (up to 31 December 2020) as well as from interviews with local experts.
UNASSIGNED: The models showed that compared to alternative initial imaging modalities, EOB-MRI was associated with higher diagnostic accuracy (fewer false-positive and fewer false-negative results). Increasing proportionate use of EOB-MRI resulted in a cost offset per patient (excluding false-negative patients) in both the US (USD 337) and China (CNY 1,443), driven by reductions in scan costs and unnecessary treatment costs. The use of EOB-MRI was also associated with a shorter average waiting time for a final diagnosis and treatment decision for patients compared to MDCT, ECCM-MRI, and CEUS.
UNASSIGNED: The findings of these models demonstrate that EOB-MRI is the most accurate and rapid imaging modality for the diagnosis of HCC in the US and China, resulting in cost offsets that may benefit the healthcare system.
