BackgroundDiabetes Mellitus (DM) is a chronic disease that is considered a global public health problem. Education and self-monitoring by diabetic patients help to optimize and make possible a satisfactory metabolic control enabling improved management and reduced morbidity and mortality. The global growth in the use of mobile phones makes them a powerful platform to help provide tailored health, delivered conveniently to patients through health apps.ObjectiveThe aim of our study was to evaluate the efficacy of mobile apps through a systematic review and meta-analysis to assist DM patients in treatment.MethodsWe conducted searches in the electronic databases MEDLINE (Pubmed), Cochrane Register of Controlled Trials (CENTRAL), and LILACS (Latin American and Caribbean Health Sciences Literature), including manual search in references of publications that included systematic reviews, specialized journals, and gray literature. We considered eligible randomized controlled trials (RCTs) conducted after 2008 with participants of all ages, patients with DM, and users of apps to help manage the disease. The meta-analysis of glycated hemoglobin (HbA1c) was performed in Review Manager software version 5.3.ResultsThe literature search identified 1236 publications. Of these, 13 studies were included that evaluated 1263 patients. In 6 RCTs, there were a statistical significant reduction (P<.05) of HbA1c at the end of studies in the intervention group. The HbA1c data were evaluated by meta-analysis with the following results (mean difference, MD −0.44; CI: −0.59 to −0.29; P<.001; I²=32%).The evaluation favored the treatment in patients who used apps without significant heterogeneity.ConclusionsThe use of apps by diabetic patients could help improve the control of HbA1c. In addition, the apps seem to strengthen the perception of self-care by contributing better information and health education to patients. Patients also become more self-confident to deal with their diabetes, mainly by reducing their fear of not knowing how to deal with potential hypoglycemic episodes that may occur.
Antimicrobial resistance (AMR) is a high priority across countries as it increases morbidity, mortality and costs. Concerns with AMR have resulted in multiple initiatives internationally, nationally and regionally to enhance appropriate antibiotic utilization across sectors to reduce AMR, with the overuse of antibiotics exacerbated by the COVID-19 pandemic. Effectively tackling AMR is crucial for all countries. Principally a narrative review of ongoing activities across sectors was undertaken to improve antimicrobial use and address issues with vaccines including COVID-19. Point prevalence surveys have been successful in hospitals to identify areas for quality improvement programs, principally centering on antimicrobial stewardship programs. These include reducing prolonged antibiotic use to prevent surgical site infections. Multiple activities centering on education have been successful in reducing inappropriate prescribing and dispensing of antimicrobials in ambulatory care for essentially viral infections such as acute respiratory infections. It is imperative to develop new quality indicators for ambulatory care given current concerns, and instigate programs with clear public health messaging to reduce misinformation, essential for pandemics. Regular access to effective treatments is needed to reduce resistance to treatments for HIV, malaria and tuberculosis. Key stakeholder groups can instigate multiple initiatives to reduce AMR. These need to be followed up.
Introduction and Objective: Dengue virus is a serious global health problem with an estimated 3.97 billion people at risk for infection worldwide. In December 2015, the first vaccine (CYD-TDV) for dengue prevention was approved in Brazil, developed by Sanofi Pasteur. However, given that the vaccine will potentially be paid via the public health system, information is need regarding consumers’ willingness to pay for the dengue vaccine in the country as well as discussions related to the possible inclusion of this vaccine into the public health system. This was the objective of this research.Methods: We conducted a cross-sectional study with residents of Greater Belo Horizonte, Minas Gerais, about their willingness to pay for the CYD-TDV vaccine.Results: 507 individuals were interviewed. These were mostly female (62.4%) had completed high school (62.17%), were working (74.4%), had private health insurance (64.5%) and did not have dengue (67.4%). The maximum median value of consumers’ willingness to pay for CYD-TDV vaccine is US$33.61 (120.00BRL) for the complete schedule and US$11.20 (40.00BRL) per dose. At the price determined by the Brazil’s regulatory chamber of pharmaceutical products market for the commercialization of Dengvaxia® for three doses, only 17% of the population expressed willingness to pay for this vaccine.Conclusion: Brazil is currently one of the largest markets for dengue vaccine and the price established is a key issue. We believe the manufacturer should asses the possibility of lower prices to reach a larger audience among the Brazilian population.
Background: Chikungunya fever is an important infectious disease transmitted by the bite of Aedes genus mosquitoes infected with the Chikungunya Virus (CHIKV). Information about consumers' willingness to pay (WTP) for a hypothetical vaccine against CHIKV can help discussions about prices and funding in countries with limited resources. Methods: Cross-sectional study among adult residents of Minas Gerais, Brazil, asking if they were willing to pay the price for a hypothetical chikungunya vaccine defined by the authors with an effective protection of 80% and the possibility of local and systemic side-effects. Residents were provided with information if not familiar with the virus. .90 (720.00BRL). We included this aspect due to issues with any anchoring effect. Results: 496 individuals were interviewed. Among these, 23 were excluded. Most of the respondents were female (57.3%), had completed at least high school (90.7%), were employed (87.7%) and had private health insurance (62.6%). The median value of the WTP was US$ 31.17 (120.00 BRL) for a unique dose vaccine. There was a statistical significant correlation with monthly family income and access to private health insurance. Conclusion: This study can contribute to decision-making about potential prices for a CHIKV vaccine when it becomes available in Brazil. We also showed the anchoring effect as a possible influence on consumers' WTP in studies with similar techniques. Finally, we encourage the development of a chikungunya virus vaccine to benefit the Brazilian population.
Background: Zika virus is a newly emerging infection, associated with increasingly large outbreaks especially in tropical countries such as Brazil. A future Zika vaccine can contribute to decreasing the number of cases and associated complications. Information about consumers' willingness to pay (WTP) for a hypothetical Zika vaccine can help price setting discussions in the future in Brazil, starting with the private market. Methods: A cross-sectional study conducted among residents of Minas Gerais, Brazil, regarding their WTP for a hypothetical Zika Vaccine. The mean effective protection was 80%, with the possibility of some local and systemic sideeffects. Results: 517 people were interviewed. However, 30 would not be vaccinated even if the vaccine was free. Most of the resultant interviewees (489) were female (58.2%), had completed high school (49.7%), were employed (71.2%), had private health insurance (52.7%) and did not have Zika (96.9%). The median individual maximum willingness to pay for this hypothetical Zika vaccine (one dose) was US$31.34 (BRL100.00). Conclusion: Such discussions can contribute to decision-making about prices once a Zika vaccine becomes available in Brazil alongside other ongoing programmes to control the virus.
Summary Dengue virus is known to modulate host cell lipid metabolism in order to promote efficient viral replication. Recent studies have focused on circulating lipids as potential biomarkers of dengue severity; however, the results obtained so far lack the consistency to establish a definite relationship between the two. Therefore, in the present study, we investigated serum lipids as potential biomarkers of dengue severity by conducting a meta‐analysis of the currently available clinical data. Nine studies that evaluated 1,953 patients were included in the review, many of which were cross‐sectional (44.4%) and conducted in Asian countries (55.5%). These studies observed the presence of lipids in serum samples (77%) of patients in the acute phase of the disease (88.8%). Circulating total‐cholesterol (P = .001) and LDL (P = .001) levels, but not HDL (P = .07), VLDL (P = .9) and triglyceride (P = .57) levels, were inversely and significantly correlated with dengue severity. Total cholesterol (P ≤ .001) and LDL (P = .001) were also useful in determining the risk of hypovolemic shock in patients with severe dengue. Subgroup analysis showed that factors, such as design (cross‐sectional vs cohort), racial‐ethnic differences (Asian vs Latin Americans), and age range (children vs adult) influenced the correlation and also contributed to the high level of heterogeneity in the studies. Our meta‐analysis demonstrates that total‐cholesterol and LDL‐cholesterol levels should be explored as routine laboratory markers for dengue severity, as they will help in employing an appropriate patient therapy, and thus optimize the use of available resources.
Aim: Global expenditure on medicines is rising up to 6% per year driven by increasing prevalence of non-communicable diseases (NCDs) and new premium priced medicines for cancer, orphan diseases and other complex areas. This is difficult to sustain without reforms. Methods: Extensive narrative review of published papers and contextualizing the findings to provide future guidance. Results: New models are being introduced to improve the managed entry of new medicines including managed entry agreements, fair pricing approaches and monitoring prescribing against agreed guidance. Multiple measures have also successfully been introduced to improve the prescribing of established medicines. This includes encouraging greater prescribing of generics and biosimilars versus originators and patented medicines in a class to conserve resources without compromising care. In addition, reducing inappropriate antibiotic utilization. Typically, multiple measures are the most effective. Conclusion: Multiple measures will be needed to attain and retain universal healthcare.
CYD-TDV showed moderate efficacy in children and adolescents. From the immunogenicity results in adults, we can expect satisfactory efficacy from vaccination in this population.
