RESUMO

BACKGROUND: There is little evidence of the influence of dietary patterns on mortality risk among adults 80 years or older ("oldest-old"). We evaluated the association between the Simplified Healthy Eating index (SHE-index) and mortality among Chinese oldest-old. METHODS: Population-based cohort study from the Chinese Longitudinal Healthy Longevity Survey (CLHLS 1998-2014, n = 35 927), conducted in 22 Chinese provinces, were pooled for analysis. The first seven waves of the CLHLS (1998, 2000, 2002, 2005, 2008-09, 2011-12, and 2013-2014) were utilized, with follow-up to the last wave (2018) (range 0-21 years). The SHE-index was collected in each wave, and was constructed from intake frequency of nine dietary variables, with a higher score indicating better diet quality. Cox proportional hazards model with dietary patterns as a time-varying exposure was employed to analyze the relationship between SHE-index and mortality. RESULTS: At baseline, the median age of all participants was 92 years (25th percentile, 85 years; 75th percentile, 100 years). In multivariable models, the hazard ratios (95% confidence intervals) for SHE-index quartile 2, quartile 3 and quartile 4 versus quartile1 were 0.91 (0.88, 0.93), 0.89 (0.86, 0.92) and 0.82 (0.78, 0.85), respectively. Results were generally consistent for men and women and in a large number of sensitivity analyses. CONCLUSIONS: Healthier eating patterns were associated with a significant reduction in the risk of all-cause mortality among Chinese oldest-old, lending support to the importance of life-long adherence to healthy diet into advanced old age.

RESUMO

OBJECTIVE: To derive the health utility scores of type 2 diabetes (T2D) patients using basal insulin (BI) with diverse characteristics in China. METHODS: The study used the data of insulin-using T2D patients on BI treatment enrolled in the BEYOND II study, which is a multi-center, observational study from 78 hospitals nationwide. The 3-level EQ-5D (EQ-5D-3L) questionnaire was administered to each patient to derive their health utility scores using the EQ-5D-3L value set for China. Patients' clinical and sociodemographic information were retrieved from their electronic case report form (eCRF). Ordinary least-square models with different specifications were explored to identify the best-fitting model to predict the utility scores. RESULTS: The sample (n = 12,583) achieved a mean (standard deviation) EQ-5D-3L utility score of 0.936 (0.120). According to the model, a Chinese male who was younger than 59 years, not underweight, diagnosed with T2D shorter than 10 years, with controlled plasma glucose and free of diabetes complications/comorbidities, would have a mean utility of 0.993. Being female, older age, underweight, and higher plasma glucose, longer diabetes duration was negatively related to EQ-5D-3L scores. Comorbidities and seven of eleven complications were associated with utility decrement. Interactions between some complications were also discovered. CONCLUSIONS: The derived health utility scores for diabetes complications could facilitate the assessment of the cost-effectiveness of health interventions for Chinese insulin-using T2D patients.

RESUMO

INTRODUCTION: The aim of this study was to compare the efficacy, safety and cost-utility (from the Chinese health insurance perspective) of lixisenatide and insulin regimens in patients with type 2 diabetes mellitus (T2DM) inadequately controlled on oral antidiabetic drugs (OADs). METHODS: A comprehensive literature search of English (PubMed and Cochrane Library) and Chinese (CNKI and WanFang) language databases was performed, and head-to-head relevant randomized controlled trials (RCTs) were retrieved and analyzed by performing a mixed-treatment comparison (MTC) meta-analysis for efficacy and safety endpoints. A cost-utility analysis was then conducted using the IQVIA CORE Diabetes Model to compare the lifetime pharmacoeconomic profiles among the treatment groups. RESULTS: Eleven RCTs were included in this MTC meta-analysis. Regarding glycated hemoglobin targets, lixisenatide was similar to both basal insulin (mean difference [MD] 0.27%; 95% credible interval [CrI] 0.02%, 0.57%) and premixed insulin (MD 0.32%; 95% CrI - 0.01%, 0.66%), respectively. Statistically significant differences were found for changes in body weight in favor of lixisenatide compared with basal insulin (MD - 3.22 kg; 95% CrI - 5.51 kg, - 0.94 kg) and premixed insulin (MD - 2.68 kg; 95% CrI - 5.16 kg, - 0.20 kg). The relative risk (RR) of symptomatic hypoglycemia associated with lixisenatide was also significantly lower than that associated with basal insulin (RR 0.22; 95% CrI 0.09, 0.52) and premixed insulin (RR 0.17; 95% CrI 0.07, 0.41). The cost-utility analysis yielded results of ¥61,072 ($8565, vs. basal insulin) and ¥127,169 ($17,836, vs. premixed insulin) per quality-adjusted life year gained, with both values falling within the willingness-to-pay threshold in China. CONCLUSIONS: For T2DM patients inadequately controlled on OADs, lixisenatide was shown to be comparable to basal insulin and premixed insulin in terms of HbA1c and better than both of the latter in terms of both body weight loss and hypoglycemia. Lixisenatide was also a cost-effective treatment option from the perspective of Chinese health insurance.

RESUMO

BACKGROUND: Both amisulpride and olanzapine are leading treatments for schizophrenia in China. This study aimed to investigate the long-term cost-effectiveness of amisulpride and olanzapine in the treatment of schizophrenia in China. METHODS: A decision-analytic Markov model was developed to simulate the lifetime clinical and economic outcomes of schizophrenia treatment from the healthcare payer perspective. The long-term costs and QALYs were estimated. Sensitivity analyses were performed to explore the impact of variance of parameters on the results. RESULTS: Treatment with amisulpride provided an effectiveness gain of 16.59 QALYs at an average cost of USD 25,884 whereas olanzapine resulted in 16.38 QALYs at a cost of USD 34,839 over a lifetime horizon. One-way sensitivity analysis suggested that the most sensitive variable was the unit cost of olanzapine. In a probabilistic sensitivity analysis based on a Monte Carlo simulation with a lifetime horizon, the probability of amisulpride being cost-effective was 99.8% at a willingness-to-pay threshold of USD 9,322, the GDP per capita in China 2018. A scenario analysis with updated olanzapine unit cost suggested an ICER of 7,857 USD/QALY. CONCLUSIONS: Amisulpride is likely to be a cost-effective option with increased effectiveness compared with olanzapine in the treatment of schizophrenia patients in China.

RESUMO

AIMS: To evaluate the comparative efficacy and safety of lixisenatide combined with basal insulin (BI) vs intensive premix insulin (premix), BI plus prandial insulin with the main meal (basal-plus) or progressively covering all meals (basal-bolus) in patients with type 2 diabetes mellitus (T2DM) inadequately controlled by BI, and the long-term cost-effectiveness of lixisenatide from a Chinese healthcare system perspective. MATERIALS AND METHODS: Randomized controlled trials (RCTs) published between 1998 and 2018 were systematically searched. The clinical efficacy and safety of each treatment were compared by network meta-analysis (NMA). The IQVIA CORE Diabetes Model was used to estimate the lifetime quality-adjusted life-years (QALYs) and direct medical costs of patients treated with different strategies. RESULTS: Eight RCTs were finally included. Lixisenatide plus BI showed a similar reduction in HbA1c from baseline compared with premix, basal-plus and basal-bolus. There were significant differences in the change of body weight in favour of lixisenatide plus BI compared with the three insulin regimens. The risk of symptomatic hypoglycaemia of lixisenatide plus BI was significantly lower compared with premix and basal-bolus. Lixisenatide plus BI was cost-effective compared with premix, basal-plus and basal-bolus with incremental cost-effectiveness ratios of Chinese yuan (CNY) 87 219, 48 173 and 48 670 per QALY gained, respectively, under the threshold of three times the gross domestic product (GDP) per capita in China. CONCLUSIONS: Lixisenatide plus BI shows a similar HbA1c reduction compared with insulin regimens, accompanied by lower risk of hypoglycaemia and greater body weight reduction. It is a cost-effective treatment alternative for patients with T2DM inadequately controlled by BI in China.

RESUMO

Objective: To compare the cost per responder of lixisenatide versus insulin glulisine once daily (basal-plus) and three times daily (basal-bolus) on top of basal insulin for the treatment of patients with type 2 diabetes mellitus (T2DM) inadequately controlled by basal insulin in China.Methods: The cost per responder was estimated based on clinical data obtained from the GetGoal Duo-2 clinical trial and direct medical costs from the perspective of the Chinese healthcare system over a 52-week time horizon. The response was assessed at week 26 in the clinical trial, which was extrapolated to 52 weeks to estimate the annual cost per responder. Responders were primarily defined using a composite endpoint that based on an HbA1c ≤ 7.0% threshold AND no weight gain With or Without no documented symptomatic hypoglycemia. Composite endpoints with varied HbA1c thresholds were defined in secondary analyses.Results: For the composite endpoint of HbA1c threshold ≤7.0% AND no weight gain, the annual cost per responder results were 96,722 CNY, 122,552 CNY and 135,926 CNY (14,616, 18,520 and 20,541 US dollars) for lixisenatide combined with basal insulin, basal-plus, and basal-bolus, respectively. For the composite endpoint of HbA1c threshold ≤7.0% AND no weight gain AND no documented symptomatic hypoglycemia, the annual cost per responder results were 136,290 CNY, 231,487 CNY and 222,424 CNY (20,596, 34,982 and 33,612 US dollars) for lixisenatide combined with basal insulin, basal-plus, and basal-bolus, respectively. The secondary analyses proved similar results.Conclusion: Lixisenatide combined with basal insulin is associated with a lower cost per responder compared with basal-plus and basal-bolus for T2DM patients inadequately controlled by basal insulin in China.

RESUMO

Objectives: To estimate the direct medical costs (DMCs) and healthcare resource utilization (HRU) of type 2 diabetes mellitus (T2DM)-related complications in China. Methods: Data from a total of 74,507 patients were extracted from the 2015 China Health Insurance Research Association Claims Database. The complications determined by primary diagnoses were categorized into three groups: 1) for mild acute and local chronic complications, both outpatients and inpatients were considered; 2) for severe acute complications, only inpatiens were considered; 3) for systemic chronic complications, a 1:1 propensity-score matching was performed to calculate the incremental DMCs and HRU of preexisting and new-onset patients. Results: Among the mild acute and local chronic complications, the DMCs and HRU per event were the highest for gangrene and laser treatment. Of the severe acute complications, the DMCs and HRU per event were highest for hyperosmotic nonketonic diabetic coma (HNDC), followed by severe hypoglycemia and ketosis. For systemic chronic complications, the DMCs and HRU associated with dialysis and myocardial infarction were the highest both in patients with new-onset complications and preexisting complications. Conclusions: The estimated economic data are required for policy decisions to optimize resource allocation and to evaluate different approaches for disease management.

RESUMO

BACKGROUND: To conduct an indirect treatment comparison of patients with high-volume mHSPC and a cost analysis between Abi-ADT and Doc-ADT therapies in China. METHODS: The Bucher technique for indirect treatment comparison was used. A cost analysis was conducted from both healthcare and patient perspectives. RESULTS: The indirect treatment comparison demonstrated no significant difference in PFS for Abi-ADT versus Doc-ADT (HR: 0.84, 95% CI 0.66-1.07). Doc-ADT therapy costs less than Abi-ADT, with potential savings of up to RMB 887,057 per patient from the healthcare perspective and RMB 226,210 per patient from the patient perspective. CONCLUSIONS: No significant differences in PFS between Doc-ADT and Abi-ADT therapy for patients with high-volume mHSPC. Doc-ADT therapy is a cost-saving alternative to Abi-ADT in China.

RESUMO

INTRODUCTION: To evaluate the efficacy and safety as well as the long-term cost-effectiveness of insulin glargine 100 U/mL (IGlar) versus insulin degludec (IDeg) for the treatment of type 2 diabetes mellitus (T2DM) from the Chinese healthcare system perspective. METHODS: A systematic search of English and Chinese electronic databases for randomized controlled trials (RCTs) comparing IGlar with IDeg for the treatment of T2DM was performed, followed by a meta-analysis to compare the efficacy and safety of IGlar versus IDeg. The CORE Diabetes Model was used to estimate lifetime costs, quality-adjusted life years (QALYs) gained, and cost-effectiveness of IGlar versus IDeg. One-way and probabilistic sensitivity analyses were conducted to assess the underlying parameter uncertainty. RESULTS: Six RCTs were included in the meta-analysis. The IGlar group showed a statistically significant decrease in glycated hemoglobin (HbA1c) from baseline compared to the IDeg group (mean difference [MD] 0.08%, 95% confidence interval [CI] 0.01-0.14%, P = 0.02). Body mass index (BMI) control was numerically better in the IGlar group than in the IDeg group (MD 0.07 kg/m2, 95% CI - 0.01 to 0.14 kg/m2, P = 0.08). In terms of hypoglycemia, the incidence of non-severe overall hypoglycemia was comparable between the IDeg and IGlar patient groups (P > 0.05), while the incidence of non-severe nocturnal hypoglycemia (relative risk [RR 0.79], 95% CI 0.70-0.90, P < 0.01) and the event rates of non-severe overall (RR 0.91, 95% CI 0.85-0.97, P < 0.01) and non-severe nocturnal hypoglycemia (RR 0.91, 95% CI 0.85-0.97, P < 0.01) were lower in the IDeg group. The incidences and event rates of both severe overall and nocturnal hypoglycemia were similar for the two groups (P > 0.05). The cost-effectiveness analysis showed that IGlar is the dominant treatment option compared with IDeg, with a lifetime savings of 1004 Chinese yuan in direct medical costs and a net gain of 0.015 QALYs per patient. Both one-way and probabilistic sensitivity analyses confirmed the robustness of the results. CONCLUSIONS: IGlar is a cost-saving option with incremental effectiveness compared with IDeg for the treatment of T2DM in China. FUNDING: Sanofi China.

RESUMO

Natural polyphenols are a large class of phytochemicals with neuroprotective effects. Four polyphenolic compounds: hesperidin, icariin, dihydromyricetin and baicalin were selected to evaluate their effects on Alzheimer's disease (AD). We analyzed by an inverse docking procedure (INVDOCK) the potential protein targets of these polyphenols within the KEGG AD pathway. Consequently, their therapeutic effects were evaluated and compared in a transgenic APP/PS1 mouse model of AD. These polyphenols were docked to several targets, including APP, BACE, PSEN, IDE, CASP, calpain and TNF-α, suggesting potential in vivo activities. Five month old transgenic mice were treated with these polyphenols. Icariin and hesperidin restored behavioral deficits and ameliorated Aß deposits in both the cortex and hippocampus while baicalin and dihydromyricetin showed no substantial effects. Our findings suggest that hesperidin and icariin could be considered potential therapeutic candidates of human AD.

RESUMO

BACKGROUND: Despite the significant burden of stroke in rural China, secondary prevention of stroke is suboptimal. This study aims to develop a SINEMA for the secondary prevention of stroke in rural China and to evaluate the effectiveness of the model compared with usual care. METHODS: The SINEMA model is being implemented and evaluated through a 1-year cluster-randomized controlled trial in Nanhe County, Hebei Province in China. Fifty villages from 5 townships are randomized in a 1:1 ratio to either the intervention or the control arm (usual care) with a target to enroll 25 stroke survivors per village. Village doctors in the intervention arm (1) receive systematic cascade training by stroke specialists on clinical guidelines, essential medicines and behavior change; (2) conduct monthly follow-up visits with the support of a mobile phone application designed for this study; (3) participate in virtual group activities with other village doctors; 4) receive performance feedback and payment. Stroke survivors participate in a health education and project briefing session, receive monthly follow-up visits by village doctors and receive a voice message call daily as reminders for medication use and physical activities. Baseline and 1-year follow-up survey will be conducted in all villages by trained staff who are blinded of the randomized allocation of villages. The primary outcome will be systolic blood pressure and the secondary outcomes will include diastolic blood pressure, medication adherence, mobility, physical activity level and quality of life. Process and economic evaluation will also be conducted. DISCUSSION: This study is one of very few that aim to promote secondary prevention of stroke in resource-constrained settings and the first to incorporate mobile technologies for both healthcare providers and patients in China. The SINEMA model is innovative as it builds the capacity of primary healthcare workers in the rural area, uses mobile health technologies at the point of care, and addresses critical health needs for a vulnerable community-dwelling patient group. The findings of the study will provide translational evidence for other resource-constrained settings in developing strategies for the secondary prevention of stroke.

RESUMO

BACKGROUND: Amisulpride was introduced into China in 2010 as a second-generation atypical antipsychotic, while olanzapine has been on the market since 1999 as one of the leading treatments for schizophrenia in China. Since more Chinese patients are gaining access to amisulpride, the study aims to compare the efficacy, safety, and costs between amisulpride and olanzapine for schizophrenia treatment in China. METHODS: PubMed, Embase, the Cochrane library, China National Knowledge Infrastructure (CNKI) and WanFang database were systematically searched for randomized controlled trials (RCTs) up to July 2018. The Cochrane Risk of Bias tool was utilized to assess the quality of included studies. A meta-analysis was performed to compare the efficacy and safety of amisulpride and olanzapine, followed by a cost-minimization analysis using local drug and medical costs reported in China. RESULTS: Twenty RCTs with 2000 patients were included in the systematic review. There were no significant differences between amisulpride and olanzapine on efficacy measures based on scores from the Positive and Negative Syndrome Scale, the Scale for the Assessment of Negative Symptoms, the Brief Psychiatric Rating Scale and the Clinical Global Impressions-Severity or Improvement. For safety outcomes, amisulpride was associated with lower fasting blood glucose and less abnormal liver functions as well as significantly lower risks of weight gain, constipation, and somnolence; olanzapine was associated with significantly lower risks of insomnia and lactation/amenorrhea/sexual hormone disorder. No significant differences were found in risks of extrapyramidal symptoms (EPS), tremor, akathisia, abnormal corrected QT interval. Cost-minimization analysis showed that amisulpride was likely to be a cost-saving alternative in China, with potential savings of 1358 Chinese Yuan (CNY) per patient for a three-month schizophrenia treatment compared with olanzapine. CONCLUSION: As the first meta-analysis and cost-minimization analysis comparing the efficacy, safety and cost of amisulpride and olanzapine within a Chinese setting, the study suggests that amisulpride may be an effective, well-tolerated, and cost-saving antipsychotic drug alternative in China.

RESUMO

Tibetan minipig is an important animal model for human diseases. The anterior pituitary is the master gland responsible for growth, reproduction, and metabolism and is regulated by thousands of miRNAs/mRNAs molecules. However, little is known about miRNAs and their relationships with mRNAs in Tibetan minipig anterior pituitary. Using microarray and mRNA-Sequencing, we identified 203 miRNAs and 12,040 mRNA transcripts from the anterior pituitary of Tibetan minipigs. These miRNAs were corresponding to 194 hairpin precursors, 25 miRNA clusters and 24 miRNA families. In addition, 64 intragenic miRNAs were annotated. Using three bioinformatic algorithms (TargetScan, miRanda and RNAhybrid), 359,184 possible miRNA-mRNA interactions were predicted, and an integrated network of miRNAs and pituitary-specific mRNA transcripts was established. To validate the predicted results, the degradome sequencing was employed to confirm miRNA-mRNA interactions, totally, 30 miRNA-mRNA pairs were identified. The present study provided a general overview of miRNA and mRNA annotation in Tibetan minipig anterior pituitary and established a miRNA-mRNA interactions database at the whole genome scale, which helps shed light on the molecular mechanisms in the anterior pituitary of pigs even other mammals.

RESUMO

Hesperidin, a member of the flavanone group of flavonoids, can be isolated in large amounts from the rinds of some citrus species. Considering the wide range of pharmacological activities and widespread application of hesperidin, this paper reviews preclinical and clinical trials of hesperidin and its related compounds, including their occurrence, pharmacokinetics, and some marketed products available. Preclinical studies and clinical trials demonstrated therapeutical effects of hesperidin and its aglycone hesperetin in various diseases, such as neurological disorders, psychiatric disorders, and cardiovascular diseases and others, due to its anti-inflammatory, antioxidant, lipid-lowering, and insulin-sensitizing properties.

RESUMO

FSH plays an essential role in processes involved in human reproduction, including spermatogenesis and the ovarian cycle. While the transcriptional regulatory mechanisms underlying its synthesis and secretion have been extensively studied, little is known about its posttranscriptional regulation. A bioinformatics analysis from our group indicated that a microRNA (miRNA; miR-361-3p) could regulate FSH secretion by potentially targeting the FSHB subunit. Herein, we sought to confirm these findings by investigating the miR-361-3p-mediated regulation of FSH production in primary pig anterior pituitary cells. Gonadotropin-releasing hormone (GnRH) treatment resulted in an increase in FSHB synthesis at both the mRNA, protein/hormone level, along with a significant decrease in miR-361-3p and its precursor (pre-miR-361) levels in time- and dose-dependent manner. Using the Dual-Luciferase Assay, we confirmed that miR-361-3p directly targets FSHB. Additionally, overexpression of miR-361-3p using mimics significantly decreased the FSHB production at both the mRNA and protein levels, with a reduction in both protein synthesis and secretion. Conversely, both synthesis and secretion were significantly increased following miR-361-3p blockade. To confirm that miR-361-3p targets FSHB, we designed FSH-targeted siRNAs, and co-transfected anterior pituitary cells with both the siRNA and miR-361-3p inhibitors. Our results indicated that the siRNA blocked the miR-361-3p inhibitor-mediated upregulation of FSH, while no significant effect on non-target expression. Taken together, our results demonstrate that miR-361-3p negatively regulates FSH synthesis and secretion by targeting FSHB, which provides more functional evidence that a miRNA is involved in the direct regulation of FSH.

RESUMO

BACKGROUND: Despite the strong uptake of mobile health (mhealth) technology targeted at cardiovascular care, it is still unclear if this improves adherence to therapy and patient-related outcomes in those with established cardiovascular disease. METHODS: A systematic search of English and Chinese language studies was conducted to investigate the benefit of mhealth technology for the secondary prevention of cardiovascular disease. RESULTS: Twenty-seven studies with 5165 patients were included in the systematic review. Patients in the mhealth group showed increased adherence to medical therapy (odds ratio [OR], 4.51; P < 0.00001), as well as increased adherence to pharmacologic and nonpharmacologic therapy (OR, 3.86; P < 0.00001). Patients in the mhealth group showed the ability to meet recommended blood pressure targets (OR, 2.80; P < 0.001) with a trend toward the ability to meet exercise goals (OR, 2.55; P = 0.07), however, no significant difference in smoking cessation (OR, 1.42; P = 0.45) and the ability to meet lipid target levels (OR, 1.16; P = 0.29) was found. Patients in the mhealth group did not show a reduction in hospital readmission (OR, 0.93; P = 0.96), with a small number of studies showing a reduction in angina (OR, 0.23; P = 0.005), and a decrease in transient ischemic attack/stroke recurrence in those with cerebrovascular disease (OR, 0.18; P < 0.0001) and a trend toward lower observed mortality rate (OR, 0.19; P = 0.06). CONCLUSIONS: The mhealth group compared with the usual care group had increased adherence to medical therapy, ability to reach blood pressure targets, exercise goals, and showed less anxiety and increased awareness of diet and exercise. There was no difference in smoking cessation, ability to meet low-density lipoprotein cholesterol targets, and hospital readmission.

RESUMO

Survivors of ischemic stroke are still at a significant risk for recurrence. Antiplatelet agents are the treatment of first choice for long-term secondary prevention of vascular events. This study aims to assess a health promotion program on medication adherence to antiplatelet therapy among ischemic stroke patients in Hainan province, China. In five hospitals from the intervention group, four highly experienced physicians trained 62 neurologists, who in turn trained 613 stroke patients to improve their awareness and adherence to antiplatelet therapy. Physicians and patients of the control group received usual stroke management programs. After one-year follow-up, the proportion of patients who took the antiplatelet therapy increased significantly in the intervention group, reaching 73.2%, with a pre-post difference between two arms of 22.9% ( P < 0.01). There was also a significant net increase in the proportion of patients with awareness of antiplatelet therapy (24.4%, P < 0.01). Multivariate analysis illustrated health promotion program, higher education, annual household income, insurance, and medical status affected antiplatelet drug use in stroke patients. In conclusion, the health promotion program, based on a train-the-trainer approach, showed positive effects on awareness of and adherence to antiplatelet therapy, which has the potential to be scaled up to other resource-limited areas.

RESUMO

Coronary heart disease (CHD) is a major disease burden globally and in China, but secondary prevention among CHD patients remains insufficient. Mobile health (mHealth) technology holds promise for improving secondary prevention but few previous studies included both provider-facing and patient-directed measures. We conducted a physician needs assessment survey (n = 59), physician interviews (n = 6), one focus group and a short cellphone message validation survey (n = 14) in Shanghai and Hainan, China. Based on these results, we developed a multifaceted mHealth intervention that includes: (1) a provider-facing bilingual mobile app guiding prescription of evidence-based medications for secondary prevention and (2) a patient-directed short messaging system automatically sending reminders to patients regarding medication adherence and lifestyle changes (4-5 messages per week for 12 weeks). This combined intervention has the potential to improve secondary prevention of CHD and to be adapted to other countries and healthcare conditions.

RESUMO

Although stroke incidence in high-income countries (HICs) decreased over the past four decades, it increased dramatically in low- and middle-income countries (LMICs). In this review, we describe the current status of primary prevention, treatment, and management of acute stroke and secondary prevention of and rehabilitation after stroke in LMICs. Although surveillance, screening, and accurate diagnosis are important for stroke prevention, LMICs face challenges in these areas due to lack of resources, awareness, and technical capacity. Maintaining a healthy lifestyle, such as no tobacco use, healthful diet, and physical activity are important strategies for both primary and secondary prevention of stroke. Controlling high blood pressure is also critically important in the general population and in the acute stage of hemorrhagic stroke. Additional primary prevention strategies include community-based education programs, polypill, prevention and management of atrial fibrillation, and digital health technology. For treatment of stroke during the acute stage, specific surgical procedures and medications are recommended, and inpatient stroke care units have been proven to provide high quality care. Patients with a chronic condition like stroke may require lifelong pharmaceutical treatment, lifestyle maintenance and self-management skills, and caregiver and family support, in order to achieve optimal health outcomes. Rehabilitation improves physical, speech, and cognitive functioning of disabled stroke patients. It is expected that home- or community-based services and tele-rehabilitation may hold special promise for stroke patients in LMICs.
