Transitions of cardio-metabolic risk factors in the Americas between 1980 and 2014
Background: Describing the levels and trends of cardio-metabolic risk factors associated with non-communicable diseases (NCDs) is vital for monitoring progress, planning prevention and provide evidence to support policy efforts. We aimed to analyse the transition in body-mass index (BMI), obesity, blood pressure, raised blood pressure (RBP) and diabetes in the Americas, 1980-2014.
Methods: Pooled analysis of population-based studies with data on anthropometric measurements, biomarkers for diabetes, and blood pressure from adults aged 18+ years. A Bayesian model was used to estimate trends in BMI, RBP (systolic blood pressure â„140 mmHg or diastolic blood pressure â„90 mmHg) and diabetes (fasting plasma glucose â„7.0 mmol/l, history of diabetes, or diabetes treatment) from 1980 to 2014 in 37 countries and 6 sub-regions of the Americas.
Findings: 389 population-based surveys from the Americas were available. Comparing the 2014 with the 1980 prevalence estimates, the obesity ratio was the largest in the non-English-speaking Caribbean sub-region (4.71 in men and 2.50 in women) showing that the prevalence in 2014 for men is almost five times larger than it was in 1980. The English-speaking Caribbean sub-region had the largest ratio regarding diabetes (2.14 in men and 2.13 in women). Conversely, the ratio for RBP signals that the frequency of this condition has diminished across the region; the largest decrease was found in North America (0.56 in men and 0.54 in women).
Interpretation: Despite the generally high prevalence of cardio-metabolic risk factors across the Americas region, estimates also show a high level of heterogeneity in the transition between countries
Global, Regional, and Country-Specific Lifetime Risks of Stroke, 1990 and 2016
BACKGROUND The lifetime risk of stroke has been calculated in a limited number of selected populations. We sought to estimate the lifetime risk of stroke at the regional, country, and global level using data from a comprehensive study of the prevalence of major diseases. METHODS We used the Global Burden of Disease (GBD) Study 2016 estimates of stroke incidence and the competing risks of death from any cause other than stroke to calculate the cumulative lifetime risks of first stroke, ischemic stroke, or hemorrhagic stroke among adults 25 years of age or older. Estimates of the lifetime risks in the years 1990 and 2016 were compared. Countries were categorized into quintiles of the sociodemographic index (SDI) used in the GBD Study, and the risks were compared across quintiles. Comparisons were made with the use of point estimates and uncertainty intervals representing the 2.5th and 97.5th percentiles around the estimate. RESULTS The estimated global lifetime risk of stroke from the age of 25 years onward was 24.9% (95% uncertainty interval, 23.5 to 26.2); the risk among men was 24.7% (95% uncertainty interval, 23.3 to 26.0), and the risk among women was 25.1% (95% uncertainty interval, 23.7 to 26.5). The risk of ischemic stroke was 18.3%, and the risk of hemorrhagic stroke was 8.2%. In high-SDI, high-middle-SDI, and low-SDI countries, the estimated lifetime risk of stroke was 23.5%, 31.1% (highest risk), and 13.2% (lowest risk), respectively; the 95% uncertainty intervals did not overlap between these categories. The highest estimated lifetime risks of stroke according to GBD region were in East Asia (38.8%), Central Europe (31.7%), and Eastern Europe (31.6%), and the lowest risk was in eastern sub-Saharan Africa (11.8%). The mean global lifetime risk of stroke increased from 22.8% in 1990 to 24.9% in 2016, a relative increase of 8.9% (95% uncertainty interval, 6.2 to 11.5); the competing risk of death from any cause other than stroke was considered in this calculation. CONCLUSIONS In 2016, the global lifetime risk of stroke from the age of 25 years onward was approximately 25% among both men and women. There was geographic variation in the lifetime risk of stroke, with the highest risks in East Asia, Central Europe, and Eastern Europe.Peer reviewe
Global, regional, and national comparative risk assessment of 79 behavioural, environmental and occupational, and metabolic risks or clusters of risks, 1990-2015 : a systematic analysis for the Global Burden of Disease Study 2015
Background: The Global Burden of Diseases, Injuries, and Risk Factors Study 2015 provides an up-to-date synthesis of the evidence for risk factor exposure and the attributable burden of disease. By providing national and subnational assessments spanning the past 25 years, this study can inform debates on the importance of addressing risks in context. Methods: We used the comparative risk assessment framework developed for previous iterations of the Global Burden of Disease Study to estimate attributable deaths, disability-adjusted life-years (DALYs), and trends in exposure by age group, sex, year, and geography for 79 behavioural, environmental and occupational, and metabolic risks or clusters of risks from 1990 to 2015. This study included 388 risk-outcome pairs that met World Cancer Research Fund-defi ned criteria for convincing or probable evidence. We extracted relative risk and exposure estimates from randomised controlled trials, cohorts, pooled cohorts, household surveys, census data, satellite data, and other sources. We used statistical models to pool data, adjust for bias, and incorporate covariates. We developed a metric that allows comparisons of exposure across risk factorsâthe summary exposure value. Using the counterfactual scenario of theoretical minimum risk level, we estimated the portion of deaths and DALYs that could be attributed to a given risk. We decomposed trends in attributable burden into contributions from population growth, population age structure, risk exposure, and risk-deleted causespecifi c DALY rates. We characterised risk exposure in relation to a Socio-demographic Index (SDI). Findings: Between 1990 and 2015, global exposure to unsafe sanitation, household air pollution, childhood underweight, childhood stunting, and smoking each decreased by more than 25%. Global exposure for several occupational risks, high body-mass index (BMI), and drug use increased by more than 25% over the same period. All risks jointly evaluated in 2015 accounted for 57·8% (95% CI 56·6â58·8) of global deaths and 41·2% (39·8â42·8) of DALYs. In 2015, the ten largest contributors to global DALYs among Level 3 risks were high systolic blood pressure (211·8 million [192·7 million to 231·1 million] global DALYs), smoking (148·6 million [134·2 million to 163·1 million]), high fasting plasma glucose (143·1 million [125·1 million to 163·5 million]), high BMI (120·1 million [83·8 million to 158·4 million]), childhood undernutrition (113·3 million [103·9 million to 123·4 million]), ambient particulate matter (103·1 million [90·8 million to 115·1 million]), high total cholesterol (88·7 million [74·6 million to 105·7 million]), household air pollution (85·6 million [66·7 million to 106·1 million]), alcohol use (85·0 million [77·2 million to 93·0 million]), and diets high in sodium (83·0 million [49·3 million to 127·5 million]). From 1990 to 2015, attributable DALYs declined for micronutrient defi ciencies, childhood undernutrition, unsafe sanitation and water, and household air pollution; reductions in risk-deleted DALY rates rather than reductions in exposure drove these declines. Rising exposure contributed to notable increases in attributable DALYs from high BMI, high fasting plasma glucose, occupational carcinogens, and drug use. Environmental risks and childhood undernutrition declined steadily with SDI; low physical activity, high BMI, and high fasting plasma glucose increased with SDI. In 119 countries, metabolic risks, such as high BMI and fasting plasma glucose, contributed the most attributable DALYs in 2015. Regionally, smoking still ranked among the leading five risk factors for attributable DALYs in 109 countries; childhood underweight and unsafe sex remained primary drivers of early death and disability in much of sub-Saharan Africa. Interpretation: Declines in some key environmental risks have contributed to declines in critical infectious diseases. Some risks appear to be invariant to SDI. Increasing risks, including high BMI, high fasting plasma glucose, drug use, and some occupational exposures, contribute to rising burden from some conditions, but also provide opportunities for intervention. Some highly preventable risks, such as smoking, remain major causes of attributable DALYs, even as exposure is declining. Public policy makers need to pay attention to the risks that are increasingly major contributors to global burden

Minimizing measures of risk by saddle point conditions
The minimization of risk functions is becoming a very important topic due to its interesting
applications in Mathematical Finance and Actuarial Mathematics. This paper addresses
this issue in a general framework. Many types of risk function may be involved. A
general representation theorem of risk functions is used in order to transform the initial
optimization problem into an equivalent one that overcomes several mathematical caveats
of risk functions. This new problem involves Banach spaces but a mean value theorem
for risk measures is stated, and this simplifies the dual problem. Then, optimality is
characterized by saddle point properties of a bilinear expression involving the primal and
the dual variable. This characterization is significantly different if one compares it with
previous literature. Furthermore, the saddle point condition very easily applies in practice.
Four applications in finance and insurance are presented.This research was partially supported by ââWelzia Management SGIIC SA, RD_Sistemas SAââ and ââMEyCââ (Spain), Grant ECO2009-14457-C04.Publicad
Bandt-Pompe symbolization dynamics for time series with tied values: A data-driven approach
In 2002, Bandt and Pompe [Phys. Rev. Lett. 88, 174102 (2002)] introduced a successfully symbolic encoding scheme based on the ordinal relation between the amplitude of neighboring values of a given data sequence, from which the permutation entropy can be evaluated. Equalities in the analyzed sequence, for example, repeated equal values, deserve special attention and treatment as was shown recently by Zunino and co-workers [Phys. Lett. A 381, 1883 (2017)]. A significant number of equal values can give rise to false conclusions regarding the underlying temporal structures in practical contexts. In the present contribution, we review the different existing methodologies for treating time series with tied values by classifying them according to their different strategies. In addition, a novel data-driven imputation is presented that proves to outperform the existing methodologies and avoid the false conclusions pointed by Zunino and co-workers.Fil: Traversaro Varela, Francisco.

Key Steps to Reduce Suicide
a call that was dispatched as a suicide attempt. He found a young woman, her husband, their baby, and an empty bottle of Tylenol. The distraught husband said his wife had taken a large amount of the pills to try to kill herself. Jim asked the weary-looking woman, Maria, what had happened. She said she was depressed, had a bad headache, and had taken some Tylenol. Jim asked Maria directly, but compassionately, if she had been trying to kill herself. Maria would not give a clear answer, so Jim asked if she had ever attempted suicide. Then Maria started to cry and said she had attempted when she was a teenager and had vowed to never do it again. But now life was too difficult with the new baby and her husband unemployed, and she just couldnât take it anymore. Jim suggested that Maria and her husband go to the hospital to talk with a doctor to get some help for Maria, and Maria hesitantly agreed. At the hospital, Jim told the emergency department physician that Maria had taken a large amount of Tylenol, had attempted suicide in the past, and now âjust couldnât take it anymore. â The physician thanked Jim for the information and said it was helpful
