		                        			OBJECTIVE:
		                        			To compare the expected population impact of benefit and risk of aspirin treatment strategies for the primary prevention of cardiovascular diseases recommended by different guidelines in the Chinese Electronic Health Records Research in Yinzhou (CHERRY) study.
		                        		
		                        			METHODS:
		                        			A decision-analytic Markov model was used to simulate and compare different strategies of aspirin treatment, including: Strategy ①: Aspirin treatment for Chinese adults aged 40-69 years with a high 10-year cardiovascular risk, recommended by the 2020 Chinese Guideline on the Primary Prevention of Cardiovascular Diseases; Strategy ②: Aspirin treatment for Chinese adults aged 40-59 years with a high 10-year cardiovascular risk, recommended by the 2022 United States Preventive Services Task Force Recommendation Statement on Aspirin Use to Prevent Cardiovascular Disease; Strategy ③: Aspirin treatment for Chinese adults aged 40-69 years with a high 10-year cardiovascular risk and blood pressure well-controlled (< 150/90 mmHg), recommended by the 2019 Guideline on the Assessment and Management of Cardio-vascular Risk in China. The high 10-year cardiovascular risk was defined as the 10-year predicted risk over 10% based on the 2019 World Health Organization non-laboratory model. The Markov model simulated different strategies for ten years (cycles) with parameters mainly from the CHERRY study or published literature. Quality-adjusted life year (QALY) and the number needed to treat (NNT) for each ischemic event (including myocardial infarction and ischemic stroke) were calculated to assess the effectiveness of the different strategies. The number needed to harm (NNH) for each bleeding event (including hemorrhagic stroke and gastrointestinal bleeding) was calculated to assess the safety. The NNT for each net benefit (i.e., the difference of the number of ischemic events could be prevented and the number of bleeding events would be added) was also calculated. One-way sensitivity analysis on the uncertainty of the incidence rate of cardiovascular diseases and probabilistic sensitivity analysis on the uncertainty of hazard ratios of interventions were conducted.
		                        		
		                        			RESULTS:
		                        			A total of 212 153 Chinese adults, were included in this study. The number of people who were recommended for aspirin treatment Strategies ①-③ was 34 235, 2 813, and 25 111, respectively. The Strategy ③ could gain the most QALY of 403 [95% uncertainty interval (UI): 222-511] years. Compared with Strategy ①, Strategy ③ had similar efficiency but better safety, with the extra NNT of 4 (95%UI: 3-4) and NNH of 39 (95%UI: 19-132). The NNT per net benefit was 131 (95%UI: 102-239) for Strategy ①, 256 (95%UI: 181-737) for Strategy ②, and 132 (95%UI: 104-232) for Strategy ③, making Strategy ③ the most favorable option with a better QALY and safety, along with similar efficiency in terms of net benefit. The results were consistent in the sensitivity analyses.
		                        		
		                        			CONCLUSION
		                        			The aspirin treatment strategies recommended by the updated guidelines on the primary prevention of cardiovascular diseases showed a net benefit for high-risk Chinese adults from developed areas. However, to balance effectiveness and safety, aspirin is suggested to be used for primary prevention of cardiovascular diseases with consideration for blood pressure control, resulting in better intervention efficiency.

		                        			Diabetic kidney disease (DKD) is one of the major chronic complications of diabetes and is associated with a heavy disease burden. Since the release of the National Guidelines for the Prevention and Control of Diabetes in Primary Care (2018), there has been continuous improvement in the basic public health services and basic medical services of the primary care setting and an expansion of the scope of work. Therefore, more detailed technical guidelines for the prevention and management of diabetes and its complications in primary care are needed. This guide aims to promote the standardization of DKD prevention and control in primary care, to assist primary care physicians with the prevention and control of DKD, and to ensure the comprehensive management of patients with DKD. The contents include the basic requirements for the management, overview, screening, diagnosis and staging, treatment, follow-up, and referral of patients with DKD.

		                        			OBJECTIVE:
		                        			To evaluate the effectiveness of statin treatment strategies based on risk assessment for the primary prevention of cardiovascular diseases by the Western guidelines in a community-based Chinese population from economically developed areas using data from the Chinese electronic health records research in Yinzhou (CHERRY) study.
		                        		
		                        			METHODS:
		                        			A Markov model was used to evaluate the effectiveness of the following statin treatment strategies, including: (1) usual care without cardiovascular risk assessment(Strategy 0); (2) using the World Health Organization (WHO) non-laboratory-based risk charts with statin treatment for high-risk group (risk ≥ 20%) (Strategy 1); (3) using the WHO laboratory-based risk charts with statin treatment for high-risk group (risk ≥ 20%) (Strategy 2); and (4) using the Prediction for Atherosclerotic cardiovascular disease Risk in China (China-PAR) model with statin treatment for high-risk group (risk ≥ 10%, Strategy 3). According to the guidelines, adults in the medium-risk group received lifestyle intervention, and adults in the high-risk group received life-style intervention and statin treatment under these strategies. The Markov model simulated different strategies for ten years (cycles) using parameters from the CHERRY study, published data, meta-analyses and systematic reviews for Chinese. The number of cardiovascular events or deaths, as well as the number need to treat (NNT) with statin per cardiovascular event or death prevented, were calculated to compare the effectiveness of different strategies. One-way sensitivity analysis on the uncertainty of incidence rate of cardiovascular diseases, and probabilistic sensitivity analysis on the uncertainty of hazard ratios of interventions were conducted.
		                        		
		                        			RESULTS:
		                        			Totally 225 811 Chinese adults aged 40-79 years without cardiovascular diseases at baseline were enrolled. In contrast to the usual care without risk assessment-based statin treatment strategy, Strategy 1 using the WHO non-laboratory-based risk charts could prevent 3 482 [95% uncertainty interval (UI): 2 110-4 661] cardiovascular events, Strategy 2 using the WHO laboratory-based risk charts could prevent 3 685 (95%UI: 2 255-4 912) events, and Strategy 3 using the China-PAR model could prevent 3 895 (95%UI: 2 396-5 181) events. NNTs with statin per cardiovascular event prevented were 22 (95%UI: 14-54), 21 (95%UI: 14-52), and 27 (95%UI: 17-67), respectively. Strategy 3 could prevent more cardiovascular events, while Strategies 1 and 2 required fewer numbers need to treat with statin per cardiovascular event prevented. The results were consistent in the sensitivity analyses.
		                        		
		                        			CONCLUSION
		                        			The statin treatment strategies based on risk assessment for the primary prevention of cardiovascular diseases recommended by the Western guidelines could achieve substantive health benefits in adults from developed areas of China. Using the China-PAR model for cardiovascular risk assessment could prevent more cardiovascular diseases while using the WHO risk charts seems more efficient.

		                        			Background:
		                        			Cardiovascular disease is the leading cause of death in both genders worldwide. Gender differences in clinical presentation and treatment have been reported.
		                        		
		                        			Objective:
		                        			This study aims to describe and compare the cardiovascular risk factors and management strategies for primary prevention among Filipinos.
		                        		
		                        			Methods:
		                        			An analytical cross-sectional study was done on 2,082 patients at the Preventive Cardiology Clinic of a tertiary referral center in Quezon City, Philippines from January 1, 2002 to December 31, 2017.
		                        		
		                        			Results:
		                        			 Seventy-two percent of the patients were females with a higher mean age compared to males (57.67 + 10.50 vs 55.66 + 11.82, p 0.002). There were more women who were unemployed (75.2 vs 45.9, p<0.001). There was no significant difference in the prevalence of hypertension (68.6% vs 67.9%, p=0.542) and type 2 diabetes mellitus (19.8% vs 21.5%, p=0.437) in both genders. Beta blockers (24.1%), calcium channel blockers (22.9%) and angiotensin receptor blockers (22.1%) were the most commonly prescribed anti-hypertensive drugs. Biguanides were the most commonly prescribed glucose-lowering drug (11.3%). Compared to men, more women had dyslipidemia (51.8% vs 38.6%, p<0.001). Statins were more commonly prescribed in women (22.4 vs 18.1%, p=0.033).
		                        		
		                        			Conclusion
		                        			There were significantly more women seen in our Preventive Cardiology clinic. Smoking and alcoholic drinking were higher in males. BMI, total cholesterol and HDL were significantly higher in females than in males.

		                        			Objectives:
		                        			This cross-sectional study evaluates the degree of agreement between the 2018 American College of Cardiology/American Heart Association (ACC/AHA2018) and 2020 Philippine Guideline (PG2020) treatment algorithms for the primary prevention of dyslipidemia among Filipinos.
		                        		
		                        			Methodology:
		                        			This review included 159 charts of statin-naive Filipinos who are 45-79 years old. Using risk profile and lipid measurements, statin treatment recommendation was determined through the PG2020 algorithm and ACC/AHA-ASCVD Risk Estimator Plus web application. The degree of agreement was measured by Cohen’s kappa statistic with the two algorithms as independent raters.
		                        		
		                        			Results:
		                        			A total of 159 patients were included in the final analysis. There was a slight agreement with a kappa coefficient of 0.209 or 4.4% (95% CI 0.078-0.340, p=0.003). Statin treatment was recommended in 69 out of 159 patients (43.4%) by the PG2020 overlapping with ACC/AHA2018 in 56 cases (81.2%). On the other hand, 109 cases (68.6%) were recommended for statin treatment by ACC/AHA2018 overlapping with PG2020 in only 51.4%. 
		                        		
		                        			Conclusions
		                        			The low degree of agreement between the two treatment algorithms highlights the key demographic and ethnic variations in dyslipidemia management necessitating outcome-based studies to translate these differences. Overestimation of ASCVD risk calculation in the ACC/AHA2018 and consideration of important, unique risk factors among Filipinos favors the applicability of the Philippine guideline.

		                        			Cancer is a major public health issue that seriously endangers the public health and social development of China. Future initiatives for cancer prevention and control should continue to adhere to the principle of prioritizing prevention, and comprehensively implement related prevention activities nationwide. This is critical to reducing cancer burden in Chinese residents, especially in the low- and middle-income populations and those living in areas that are less economically developed. In the past several decades, the international community has significantly reduced the incidence of related cancers through primary prevention measures such as tobacco control, improved occupational hygiene, and vaccination. China has also implemented a series of exploratory primary prevention measures among high-risk groups of cancer in specific areas including Xuanwei, Qidong, and Linxian, and achieved encouraging results. However, due to the low level of systematic awareness of cancer risk factors and the lack of awareness and ability of self-health management in Chinese residents, it is urgent to develop novel research tools and methods to further reveal the causes of cancer, and establish innovative mechanisms and systems of primary prevention of cancer at population and individual levels. Based on current status of the transformation of cancer spectrum and the development of digital intelligence, it would be beneficial to establish a smart digital system for primary cancer prevention service that can cover the entire population, integrating authoritative popular science education on primary prevention of cancer, individualized cancer risk assessment, and personalized health management assistant. This will improve primary cancer prevention among the Chinese general population and can help the sustainable development of cancer prevention and control in China.

		                        			OBJECTIVE:
		                        			To evaluate the potential effectiveness of different screening strategies for cardiovascular diseases prevention in a community-based Chinese population from economically developed area of China.
		                        		
		                        			METHODS:
		                        			Totally 202 179 adults aged 40 to 74 years without cardiovascular diseases at baseline (January 1, 2010) were enrolled from the Chinese electronic health records research in Yinzhou (CHERRY) study. Three scenarios were considered: the screening strategy based on risk charts recommended by the 2020 Chinese guideline on the primary prevention of cardiovascular diseases in Chinese adults aged 40-74 years (Strategy 1); the screening strategy based on the prediction for atherosclerotic cardiovascular disease risk in China (China-PAR) models recommended by the 2019 Guideline on the assessment and management of cardiovascular risk in China in Chinese adults aged 40-74 years (Strategy 2); and the screening strategy based on the China-PAR models in Chinese adults aged 50-74 years (Strategy 3). According to the guidelines, individuals who were classified into medium- or high-risk groups after cardiovascular risk assessment by the corresponding strategies would be introduced to lifestyle intervention, while high-risk population would take medication in addition. Markov model was used to simulate different screening scenarios for 10 years (cycles), using parameters mainly from the CHERRY study, as well as published data, Meta-analyses and systematic reviews for Chinese populations. The life year gained, quality-adjusted life year (QALY) gained, number of cardiovascular disease events/deaths could be prevented and number needed to be screened (NNS) were calculated to compare the effectiveness between the different strategies. One-way sensitivity analysis on uncertainty of cardiovascular disease incidence rate and probabilistic sensitivity analysis on uncertainty of distributions for the hazard ratios were conducted.
		                        		
		                        			RESULTS:
		                        			Compared with non-screening strategy, QALYs gained were 1 433 [95% uncertainty interval (UI): 969-1 831], 1 401 (95%UI: 936-1 807), and 716 (95%UI: 265-1 111) for the Strategies 1, 2, and 3; and the NNS per QALY in the above strategies were 141 (95%UI: 110-209), 144 (95%UI: 112-216), and 198 (95%UI: 127-529), respectively. The Strategies 1 and 2 based on different guidelines showed similar effectiveness, while more benefits were found for screening using China-PAR models in adults aged 40-74 years than those aged 50-74 years. The results were consistent in the sensitivity analyses.
		                        		
		                        			CONCLUSION
		                        			Screening for cardiovascular diseases in Chinese adults aged above 40 years seems effective in coastal developed areas of China, and the different screening strategies based on risk charts by the 2020 Chinese guideline on the primary prevention of cardiovascular diseases or China-PAR models by the 2019 Guideline on the assessment and management of cardiovascular risk in China may have similar effectiveness.

		                        			OBJECTIVE:
		                        			To explore the effect of posaconazole in the primary prevention of invasive fungal disease (IFD) in the induction therapy of childhood acute lymphoblastic leukemia (ALL).
		                        		
		                        			METHODS:
		                        			From August 2018 to November 2020, 144 pediatric patients with ALL treated in Department of Pediatrics, Sun Yat-Sen Memorial Hospital, Sun Yat-Sen University were selected, 88 cases received fluconazole as IFD prophylaxis (fluconazole prophylaxis group), 56 cases received posaconazole as IFD prophylaxis (posaconazole prophylaxis group). The incidence of IFD and treatment-related adverse reactions between the two groups were compared, and the safety of posaconazole was evaluated.
		                        		
		                        			RESULTS:
		                        			The incidence of IFD in the fluconazole prophylaxis group was 20.4% (18/88), and in the posaconazole prophylaxis group was 7.1% (4/56). The incidence of IFD between the two groups was statistically significant different(P=0.030). There was no serious adverse reactions in the two groups. The incidence of mild adverse reactions in the posaconazole prophylaxis group (23.2%) was lower than that in the fluconazole prophylaxis group(39.8%), and the difference was statistically significant (P=0.039). There were 12 cases died in the fluconazole prophylaxis group and 4 in the posaconazole prophylaxis group, while no significant difference in the overall survival rate between the two groups (P=0.281).
		                        		
		                        			CONCLUSION
		                        			The effect of posaconazole in the primary prophylaxis of IFD is better and incidence of adverse reactions is lower than fluconazole. Posaconazole can be tolerated, and expected to become the first-line primary prophylaxis drug for IFD during the induction remission therapy of childhood ALL.
