Acute effects on the psychological perception of university students after participation in the "RegulACTION" workshop for the improvement of emotional health and promotion of an active lifestyle.

Introduction: Prospective research in Health Sciences and Sports Sciences warns of the need to design and implement educational program at the different stages of human development, that promote emotional competences, interpersonal competences, an adequate level of healthy physical activity as well as adherence to the Mediterranean diet and a more active lifestyle on a physical and social level. The main objective of the study was to design an intervention program on intra-and interpersonal competences together with emotional education, nutritional education and healthy physical activity, called 'RegulACTION'. Methods: The preliminary study sample consisted of 11 participants aged 21-28 years (M = 5.00, SD = 8.76) (8 female and 3 males) university students. An ad hoc questionnaire was elaborated to evaluate the participant's perception of the usefulness of the 'RegulACTION' experience and a semi-structured interview of 5 questions to assess their perception, identification of their emotions, awareness of their cognitions, emotions and behaviors in the different areas of their lives. Results: The descriptive results show that the participants are receptive to continuing training in the regulation of cognitions (thoughts) and emotions to increase their satisfaction in different areas of their lives. Regarding the qualitative results, the participants' perception, collected verbatim, is that they feel the need to apply the knowledge about personal and social emotions, as well as healthy behavior in terms of nutrition and exercise, in their daily lives. Discussion: The 'RegulACTION' program is designed based on the assessment of the prevalence of mental illness in the young adult and adult population, in line with the literature review in the area of knowledge of the theory of emotions, motivational theories and on the occasion of the development of a workshop organized.

Gender disparities in lost productivity resulting from non-communicable diseases in Mexico, 2005-2021.

Background: Non-communicable diseases (NCDs) cause long-term impacts on health and can substantially affect people's ability to work. Little is known about how such impacts vary by gender, particularly in low- and middle-income countries (LMICs), where productivity losses may affect economic development. This study assessed the long-term productivity loss caused by major NCDs among adult women and men (20-76 years) in Mexico because of premature death and hospitalisations, between 2005 and 2021. Methods: We conducted an economic valuation based on the Human Capital Approach. We obtained population-based data from the National Employment Survey from 2005 to 2021 to estimate the expected productivity according to age and gender using a two-part model. We utilised expected productivity based on wage rates to calculate the productivity loss, employing Mexican official mortality registries and hospital discharge microdata for the same period. To assess the variability in our estimations, we performed sensitivity analyses under two different scenarios. Results: Premature mortality by cancers, diabetes, chronic cardiovascular diseases (CVD), chronic respiratory diseases (CRD) and chronic kidney disease (CKD) caused a productivity loss of 102.6 billion international US dollars (Intl. USD) from 2.8 million premature deaths. Seventy-three percent of this productivity loss was observed among men. Cancers caused 38.3% of the productivity loss (mainly among women), diabetes 38.1, CVD 15.1, CRD 3.2, and CKD 5.3%. Regarding hospitalisations, the estimated productivity loss was 729.7 million Intl. USD from 54.2 million days of hospitalisation. Men faced 65.4 and women 34.6% of these costs. Cancers caused 41.3% of the productivity loss mainly by women, followed by diabetes (22.1%), CKD (20.4%), CVD (13.6%) and CRD (2.6%). Conclusions: Major NCDs impose substantial costs from lost productivity in Mexico and these tend to be higher amongst men, while for some diseases the economic burden is higher for women. This should be considered to inform policymakers to design effective gender-sensitive health and social protection interventions to tackle the burden of NCDs.

Gender and non-communicable diseases in Mexico: a political mapping and stakeholder analysis.

BACKGROUND: Mexico and other low- and middle-income countries (LMICs) present a growing burden of non-communicable diseases (NCDs), with gender-differentiated risk factors and access to prevention, diagnosis and care. However, the political agenda in LMICs as it relates to health and gender is primarily focused on sexual and reproductive health rights and preventing violence against women. This research article analyses public policies related to gender and NCDs, identifying political challenges in the current response to women's health needs, and opportunities to promote interventions that recognize the role of gender in NCDs and NCD care in Mexico. METHODS: We carried out a political mapping and stakeholder analysis during July-October of 2022, based on structured desk research and interviews with eighteen key stakeholders related to healthcare, gender and NCDs in Mexico. We used the PolicyMaker V5 software to identify obstacles and opportunities to promote interventions that recognize the role of gender in NCDs and NCD care, from the perspective of the political stakeholders interviewed. RESULTS: We found as a political obstacle that policies and stakeholders addressing NCDs do not take a gender perspective, while policies and stakeholders addressing gender equality do not adequately consider NCDs. The gendered social and economic aspects of the NCD burden are not widely understood, and the multi-sectoral approach needed to address these aspects is lacking. Economic obstacles show that budget cuts exacerbated by the pandemic are a significant obstacle to social protection mechanisms to support those caring for people living with NCDs. CONCLUSIONS: Moving towards an effective, equity-promoting health and social protection system requires the government to adopt an intersectoral, gender-based approach to the prevention and control of NCDs and the burden of NCD care. Despite significant resource constraints, policy innovation may be possible given the willingness among some stakeholders to collaborate, particularly in the labour and legal sectors. However, care will be needed to ensure the implementation of new policies has a positive impact on both gender equity and health outcomes. Research on successful approaches in other contexts can help to identify relevant learnings for Mexico.

Reliability and validity of a low-cost, wireless sensor and smartphone app for measuring force during isometric and dynamic resistance exercises.

The aim of this study was to investigate the reliability and validity of an affordable wireless force sensor in measuring mean and peak forces during resistance training.A Suiff Pro wireless force sensor (Suiff, Spain) and a MuscleLab force platform (Ergotest, Norway) were used concurrently to assess tensile load and the ground reaction force resulting from an upright row exercise. Thirteen participants (28.2 ± 5.7 years, 76.2 ± 9.6 kg, 178.2 ± 9.2 cm) performed the exercise under three velocity conditions and isometrically. Each condition involved three sets of exercise. Mean (Fmean) and peak (Fpeak) force values from both sensors were collected and compared.Suiff Pro exhibited excellent reliability for Fmean and Fpeak (ICCs = 0.99). When compared to the criterion measures, Suiff Pro showed trivial standardized bias for Fmean (Mean = 0.00 [CI 95% = 0.00 to 0.01]) and Fpeak (-0.02 [-0.04 to 0.00]). The standardized typical error was also trivial for Fmean (0.03 [0.02 to 0.03]) and Fpeak (0.07 [0.05 to 0.09]). Correlations with the MuscleLab force platform were nearly perfect: Fmean (0.97 [0.94 to 0.98]; p<0.001); Fpeak (0.96 [0.92 to 0.97]; p<0.001).The findings demonstrate that the Suiff Pro sensor is reliable and valid device for measuring force during isometric and dynamic resistance training exercises. Therefore, practitioners can confidently use this device to monitor kinematic variables of resistance training exercises and to obtain real-time augmented feedback during a training session.

Impact of cigarette price and tobacco control policies on youth smoking experimentation in Albania.

BACKGROUND: Albania has one of the highest smoking prevalence in Europe especially among the youth. There is a lack of evidence in Albania, as well as in most of Eastern Europe and middle-income countries, regarding the effect of price on smoking experimentation. OBJECTIVE: The study aims to assess the effect of price and tobacco control policies on youth smoking experimentation in Albania. METHODS: We used microdata from the Global Youth Tobacco Survey in Albania for 2004, 2009, 2015 and 2020. We constructed a pseudo-longitudinal dataset and estimated a split-population model to assess the hazard of smoking experimentation. RESULTS: Price is a significant predictor of smoking experimentation among teenagers in Albania for both males and females (p<0.001). Being male increases the odds for smoking experimentation by more than 50% as compared with females (p<0.001), whereas females appear to be more price sensitive. Peer and parent smoking are also important determinants for smoking experimentation. Introducing penalties for smokers and legal entities violating smoke-free policies implemented in 2014 is also associated with a lower hazard of smoking experimentation. CONCLUSION: Price is a significant predictor of smoking experimentation among teenagers in Albania for both males and females. A combination of increasing taxes and strengthening the rule of law to control tobacco use in public spaces, in addition to public awareness campaigns targeting both youth and smoking parents, could help to significantly reduce the probability of smoking experimentation.

Environmental and economic assessment of biodegradable and compostable alternatives for plastic materials in greenhouses.

Plastics and other materials commonly used in horticulture for plant support (e.g. raffia) and soil protection (e.g. mulching film) pose a challenge to achieving a circular economy. These materials contaminate plant residues, hampering their direct reuse due to the need for separation and cleaning. As a result, contaminated plant residues is often landfilled or incinerated. This study investigates the replacement of conventional plastic raffia and mulching film with biodegradable and compostable alternatives. Polypropylene raffia is compared with a biodegradable viscose polymer and compostable jute fibre, while polyethylene mulching film is compared with a biodegradable polylactic acid film. Conventional and novel alternatives are compared economically using Life-Cycle Costing and environmentally using Life-Cycle Assessment. The economic assessment is based on case studies with two horticultural companies in Almeria (south-eastern Spain), while the environmental analysis uses data from the Ecoinvent database. The use of biodegradable and compostable alternatives for raffia and mulching film proved to be 49% more expensive than conventional options. However, when conventional plastic waste is incinerated rather than landfilled, biodegradable and compostable alternatives have a lower carbon footprint. Although biodegradable and compostable options can be more expensive and have higher impacts in certain situations, proper waste management can lead to environmental benefits. With optimisation and incentives, these alternative options support the transition of horticulture to a sustainable circular economy.

Automatic mechanistic inference from large families of Boolean models generated by Monte Carlo tree search.

Many important processes in biology, such as signaling and gene regulation, can be described using logic models. These logic models are typically built to behaviorally emulate experimentally observed phenotypes, which are assumed to be steady states of a biological system. Most models are built by hand and therefore researchers are only able to consider one or perhaps a few potential mechanisms. We present a method to automatically synthesize Boolean logic models with a specified set of steady states. Our method, called MC-Boomer, is based on Monte Carlo Tree Search an efficient, parallel search method using reinforcement learning. Our approach enables users to constrain the model search space using prior knowledge or biochemical interaction databases, thus leading to generation of biologically plausible mechanistic hypotheses. Our approach can generate very large numbers of data-consistent models. To help develop mechanistic insight from these models, we developed analytical tools for multi-model inference and model selection. These tools reveal the key sets of interactions that govern the behavior of the models. We demonstrate that MC-Boomer works well at reconstructing randomly generated models. Then, using single time point measurements and reasonable biological constraints, our method generates hundreds of thousands of candidate models that match experimentally validated in-vivo behaviors of the Drosophila segment polarity network. Finally we outline how our multi-model analysis procedures elucidate potentially novel biological mechanisms and provide opportunities for model-driven experimental validation.

Validity of a low-cost friction encoder for measuring velocity, force and power in flywheel exercise devices.

The purpose of this study was to investigate the validity of a low-cost friction encoder against a criterion measure (strain gauge combined with a linear encoder) for assessing velocity, force and power in flywheel exercise devices. Ten young and physically active volunteers performed two sets of 14 maximal squats on a flywheel inertial device (YoYo Technology, Stockholm, Sweden) with five minutes rest between each set. Two different resistances were used (0.075 kg · m2 for the first set; 0.025 kg · m2 for the second). Mean velocity (Vrep), force (Frep) and power (Prep) for each repetition were assessed simultaneously via a friction encoder (Chronojump, Barcelona, Spain), and with a strain gauge combined with a linear encoder (MuscleLab 6000, Ergotest Technology, Porsgrunn, Norway). Results are displayed as (Mean [CI 90%]). Compared to criterion measures, mean bias for the practical measures of Vrep, Frep and Prep were moderate (-0.95 [-0.99 to -0.92]), small (0.53 [0.50 to 0.56]) and moderate (-0.68 [-0.71 to -0.65]) respectively. The typical error of estimate (TEE) was small for all three parameters; Vrep (0.23 [0.20 to 0.25]), Frep (0.20 [0.18 to 0.22]) and Prep (0.18 [0.16 to 0.20]). Correlations with MuscleLab were nearly perfect for all measures in all load configurations. Based on these findings, the friction encoder provides valid measures of velocity, force and power in flywheel exercise devices. However, as error did exist between measures, the same testing protocol should be used when assessing changes in these parameters over time, or when aiming to perform inter-individual comparisons.

A Gender-Based and Quasi-Experimental Study of the Catastrophic and Impoverishing Health-Care Expenditures in Mexican Households with Elderly Members, 2000-2020.

Latin America has experienced a rise in noncommunicable diseases (NCDs) which is having repercussions on the structuring of healthcare delivery and social protection for vulnerable populations. We examined catastrophic (CHE) and excessive (EHE, impoverishing and/or catastrophic) health care expenditures in Mexican households with and without elderly members (≥65 years), by gender of head of the households, during 2000-2020. We analyzed pooled cross-sectional data for 380,509 households from eleven rounds of the National Household Income and Expenditure Survey. Male- and female-headed households (MHHs and FHHs) were matched using propensity scores to control for gender bias in systematic differences regarding care-seeking (demand for healthcare) preferences. Adjusted probabilities of positive health expenditures, CHE and EHE were estimated using probit and two-stage probit models, respectively. Quintiles of EHE by state among FHHs with elderly members were also mapped. CHE and EHE were greater among FHHs than among MHHs (4.7% vs 3.9% and 5.5% vs 4.6%), and greater in FHHs with elderly members (5.8% vs 4.9% and 6.9% vs 5.8%). EHE in FHHs with elderly members varied geographically from 3.9% to 9.1%, being greater in less developed eastern, north-central and southeastern states. Compared with MHHs, FHHs face greater risks of CHE and EHE. This vulnerability is exacerbated in FHHs with elderly members, because of gender intersectional vulnerability. The present context, marked by a growing burden of NCDs and inequities amplified by COVID-19, makes key interlinkages across multiple Sustainable Development Goals (SDGs) apparent, and calls for urgent measures that strengthen social protection in health.

PortAqua: a low-cost, compact water quality meter for science communication.

Water quality monitoring allows communities to achieve sustainable management of water resources, which is crucial for life-supporting processes. Water quality is determined by measuring chemical, physical, and biological parameters, requiring sophisticated meters and trained specialists to perform the measurement. However, in low-income communities, water quality is determined by using human senses-smell, color, and taste-since meter acquisition is limited by costs and most people do not know how to monitor water quality. Therefore, accessible technology is necessary to empower communities to have a sustainable lifestyle. In this paper, we present the design and implementation of PortAqua, a 2-parameter water quality meter (WQM), to promote training on water quality measurement. Using basic electronic components, PortAqua is capable of measuring pH with an error of 0.4, and conductivity with an error of 33% at 85 µS cm-1, and 8.7% at 1413 µS cm-1. To demonstrate its preliminary effectiveness as a WQM and its science communication capabilities, the meter has been used in a hands-on workshop with undergraduate and graduate students. During the workshop, attendees participated in a short lecture about water quality measurement techniques and local regulations. Then, they collected water samples from a local source, measured the samples using PortAqua, and discussed the results based on the concepts and regulations. The workshop's effectiveness was evaluated through pre- and post-assessments which revealed increased knowledge of water quality regulations, measurement, and parameters at the end of the activity.

Synthesis and evaluation of a Zn-Al layered double hydroxide for the removal of ochratoxin A. Greenness assessment.

The retention behavior of a dangerous toxin, ochratoxin A (OTA), present in food samples and derivatives was evaluated using Layered Double Hydroxides (LDHs). This nanomaterial composed mostly of zinc and aluminum was synthesized by the co-precipitation method and the obtained solid was characterized by different techniques, such as XRD, FTIR, TGA, SEM, and N2 adsorption-desorption isotherms. Experimental conditions were optimized by chemometric tools. Ochratoxin A determination was performed using an ultra-high-performance liquid chromatography (UHPLC) system coupled to tandem mass spectrometry. From the findings, quantitative removal of the mycotoxin was achieved. Thus, a novel, nanostructured, innocuous, low-cost, easily synthesized material, such as the Zn-Al layered double hydroxide, is proposed for ochratoxin A removal. This might represent an effective and sustainable approach with potential applications to different types of food and feed samples.

Density of alcohol-selling outlets and prices are associated with frequent binge drinking in Mexico.

Despite the increase in the prevalence of binge drinking in Mexico studies focus on sociodemographic factors and little attention is paid on contextual factors. We estimated the association between density of alcohol outlets, price of alcoholic beverages, and binge drinking in Mexico among the population aged 12 to 65 years old who consumed alcohol during the last 12 months. Data come from different sources for alcohol consumption; availability of bar, nightclubs, saloons and stores that sell alcohol and prices of alcoholic beverages. We estimated generalized linear models for binary outcomes for the relationship between density of alcohol outlets and prices of alcoholic beverages with binge drinking at least once per year, at least once per month, and at least once per week controlling for sex, age, religion, household income and municipality size. Living in areas with a high density of alcohol-selling outlets was associated with a higher risk of binge drinking, at least once a year (RR 1.0, 95% CI: 1.0,1.1) at least once a month (RR 1.3, 95% CI: 1.2, 1.4) and weekly (RR 1.9, 95% CI: 1.6, 2.2). Living in States with lower alcohol prices was marginally associated to binge drinking at least once a year (RR 1.0, 95% CI: 1.0, 1.1) but more strongly associated to monthly (RR 1.2, 95% CI: 1.2, 1.4) and weekly binge drinking (RR 1.4, 95% CI: 1.3, 1.6). Along with strong fiscal policies, the implementation of spatial restrictions to the number of alcohol-selling outlets could help decrease binge drinking.

Health and Economic Impacts Assessment of O3 Exposure in Mexico.

Health effects related to exposure to air pollution such as ozone (O3) have been documented. The World Health Organization has recommended the use of the Sum of O3 Means Over 35 ppb (SOMO35) to perform Health Impact Assessments (HIA) for long-term exposure to O3. We estimated the avoidable mortality associated with long-term exposure to tropospheric O3 in 14 cities in Mexico using information for 2015. The economic valuation of avoidable deaths related to SOMO35 exposure was performed using the willingness to pay (WTP) and human capital (HC) approaches. We estimated that 627 deaths (95% uncertainty interval (UI): 227-1051) from respiratory diseases associated with the exposure to O3 would have been avoided in people over 30 years in the study area, which confirms the public health impacts of ambient air pollution. The avoidable deaths account for almost 1400 million USD under the WTP approach, whilst the HC method yielded a lost productivity estimate of 29.7 million USD due to premature deaths. Our findings represent the first evidence of the health impacts of O3 exposure in Mexico, using SOMO35 metrics.

Evaluation of the role of anal tone and perianal sensation examination in the assessment of suspected cauda equina syndrome.

PURPOSE: Cauda equina syndrome (CES) can present with a varied constellation of clinical signs and symptoms, which together with the time-sensitive nature of the condition and risk of catastrophic clinical outcome, presents a significant challenge to those assessing patients with this suspected diagnosis. Anal tone is commonly tested during initial assessment using a digital rectal examination (DRE). This study aims to evaluate the diagnostic value of anal tone and perianal sensation assessment in patients with suspected CES and report modern prevalence data on CES within a neurosciences centre. MATERIALS AND METHODS: Consecutive patients with suspected CES presenting over three years to the Emergency Department (ED) of a busy tertiary centre were included in the study. History and examination findings, documented in the ED notes, were assessed and these variables were correlated with the presence or absence of cauda equina compression on subsequent magnetic resonance imaging (MRI). RESULTS: Out of 1005 patients with suspected CES, 117 (11.6%) had MRI confirmed cauda equina compression (MRI + ve CES). 35% of MRI + ve patients and 31% of MRI -ve patients had reduced anal tone. Using univariate and multivariable logistic regression analyses, no associations were found between abnormal anal tone and MRI + ve CES for patients of all ages. The univariate logistic regression analysis identified altered perianal sensation to be significantly associated with MRI + ve CES in patients ≤42 years old. This association was no longer present when an adjusted multivariable logistic regression was performed. CONCLUSION: The prevalence of MRI + ve CES was 11.6%. Our findings suggest that the clinical finding of reduced anal tone has no demonstrable diagnostic value for those with suspected CES, either in itself or in combination with other clinical findings. Further studies are needed to confirm the diagnostic efficacy of assessing perianal sensation in this context.

Time-efficient three-dimensional transmural scar assessment provides relevant substrate characterization for ventricular tachycardia features and long-term recurrences in ischemic cardiomyopathy.

Delayed gadolinium-enhanced cardiac magnetic resonance (LGE-CMR) imaging requires novel and time-efficient approaches to characterize the myocardial substrate associated with ventricular arrhythmia in patients with ischemic cardiomyopathy. Using a translational approach in pigs and patients with established myocardial infarction, we tested and validated a novel 3D methodology to assess ventricular scar using custom transmural criteria and a semiautomatic approach to obtain transmural scar maps in ventricular models reconstructed from both 3D-acquired and 3D-upsampled-2D-acquired LGE-CMR images. The results showed that 3D-upsampled models from 2D LGE-CMR images provided a time-efficient alternative to 3D-acquired sequences to assess the myocardial substrate associated with ischemic cardiomyopathy. Scar assessment from 2D-LGE-CMR sequences using 3D-upsampled models was superior to conventional 2D assessment to identify scar sizes associated with the cycle length of spontaneous ventricular tachycardia episodes and long-term ventricular tachycardia recurrences after catheter ablation. This novel methodology may represent an efficient approach in clinical practice after manual or automatic segmentation of myocardial borders in a small number of conventional 2D LGE-CMR slices and automatic scar detection.

Impact of COVID-19 on the surgical volume of general surgery residents as main surgeons in a National Training Program in Costa Rica: A cross-sectional study.

ABSTRACT: To quantify the impact of coronavirus disease 19 (COVID-19) on the surgical volume of residents' medical practice in Costa Rica's General Surgery Residency Program.The COVID-19 pandemic has caused a significant disruption in people's lives. Health systems worldwide have been forced to adapt to the new normal, which has posed a challenge for medical residency programs, especially in the surgical field.This transversal study includes the surgical records of all residents of the General Surgery program who worked as main surgeons at the Mexico Hospital of the Costa Rican Social Security between December 23, 2019, and June 25, 2020.As main surgeons, a total of 10 residents performed 291 pre-pandemic surgeries and 241 pandemic surgeries.When comparing the distribution of procedures performed by residency levels, it is observed that the postgraduate year -2 increased the number of procedures performed during the pandemic period (pre-pandemic 19% vs pandemic 27%, P = .028). There was no statistically significant difference between the pre-pandemic and pandemic periods in the remaining levels.When comparing the procedures by unit, a statistically significant decrease was observed in the Endocrine-Abdominal Wall Unit (pre-pandemic 18.3% vs pandemic 5.4%, P < .001). Conversely, a statistically significant increase was identified in Surgical Emergencies Unit procedures (40.0% vs post 51.7%, P = .007). No statistically significant differences were observed in the remaining the Units.The COVID-19 pandemic had no statistically significant effect on surgeries performed by residents of the General Surgery Residency Program as main surgeons in a national training center in Costa Rica. The Department's timely measures and pro-resident attitude were the key reasons for the above results.

Abstract: Objective: Estimate the price and income elasticities of the demand for beer in Mexico. Materials and methods: Monthly series on beer sales and prices from 2007 to 2019 were used. Long-term elasticity was estimated using ordinary least squares (OLS). Short-term elasticity was estimated using a dynamic ordinary least squares (DOLS) model. Results: The price elasticity was in the long term of -1.40 (95%CI: -2.53 to -0.27) and -1.31 (95%CI: -2.46 to -0.15) in the short term. The income elasticity of demand in the long and short term was estimated at 0.86 (95%CI: 0.44-1.29 and 0.93 (95%CI: 0.51-1.34), respectively. Conclusions: The findings of this study suggest that fiscal policies may have a positive impact on the health of the population by reducing beer consumption.

Ethnic-racial inequity in health insurance in Colombia: a cross-sectional study.

OBJECTIVE: Characterize the relationship between ethnic-racial inequity and type of health insurance in Colombia. METHODS: Cross-sectional study based on data from the 2019 Quality of Life Survey. We analyzed the type of health insurance (contributory, subsidized, or none) and its relationship to ethnic-racial status and predisposing variables (sex, age, marital status), demographic variables (area and region of residence), and socioeconomic variables (education, type of employment, income, and unmet basic needs) through simple and multivariate regression analyses. The association between ethnic-racial status and type of health insurance was estimated using odds ratios (OR) and their 95% confidence intervals, through a multinomial logistic model. RESULTS: A statistically significant association was found between ethnic-racial status and type of health insurance. In comparison with the contributory system, the probabilities of being a member of the subsidized system were 1.8 and 1.4 times greater in the indigenous population (OR x 1.891; 95%CI: 1.600-2.236) and people of African descent (OR = 1.415; 95%CI: 1.236-1.620), respectively (p <0.01) than in the population group that did not identify as belonging to one of those ethnic-racial groups. CONCLUSIONS: There is an association between ethnic-racial status and type of insurance in the contributory and subsidized health systems in Colombia. Ethnic-racial status is a structural component of inequity in access to health services and heightens the disadvantages of people and population groups with low socioeconomic status.

Assessment of Concentrated Liquid Coffee Acceptance during Storage: Sensory and Physicochemical Perspective.

Concentrated liquid coffees (CLCs) refer to stored extracts stable at environmental temperature, used as ingredients in the retail market. Their low chemical stability affects the sensory profile. This study was performed in two CLCs, one without additives (BIB) and another with a mix of sodium benzoate and potassium sorbate additives (SD), stored at 25 °C for one year. Quantitative-Descriptive (QDA) and discriminant analyses permitted identifying the critical sensory attributes and their evolution over time. The concentrate without additives presented an acceptance limit of 196 days (evaluated at a 50% acceptance ratio), while the additives increased the shelf life up to 226 days (38.9% improvement). The rejection was related to a decreased aroma, increased acidity, and reduced bitterness. A bootstrapped feature selection version of Partial Least Square analysis further demonstrated that reactions of 5-caffeoylquinic acid (5CQA) and 3,5-dicaffeoylquinic acid (3,5diCQA) could cause changes in the aroma at the first degradation stage. In the following stages, changes in fructose and stearic acid contents, a key indicator of acceptance for both extracts possibly related to non-enzymatic reactions involving fructose and other compounds, might affect the bitterness and acidity. These results provided valuable information to understand flavor degradation in CLCs.

New Tools to Support the Risk Assessment Process of Nanomaterials in the Insurance Sector.

During the last decade, the use of nanomaterials, due to their multiple utilities, has exponentially increased. Nanomaterials have unique properties such as a larger specific surface area and surface activity, which may result in health and environmental hazards different from those demonstrated by the same materials in bulk form. Besides, due to their small size, they can easily penetrate through the environmental and biological barriers. In terms of exposure potential, the vast majority of studies are focused on workplace areas, where inhalation is the most common route of exposure. The main route of entry into the environment is due to indirect emissions of nanomaterials from industrial settings, as well as uncontrollable releases into the environment during the use, recycling and disposal of nano-enabled products. Accidental spills during production or later transport of nanomaterials and release from wear and tear of materials containing nanomaterials may lead to potential exposure. In this sense, a proper understanding of all significant risks due to the exposure to nanomaterials that might result in a liability claim has been proved to be necessary. In this paper, the utility of an application for smartphones developed for the insurance sector has been validated as a solution for the analysis and evaluation of the emerging risk of the application of nanotechnology in the market. Different exposure scenarios for nanomaterials have been simulated with this application. The results obtained have been compared with real scenarios, corroborating that the use of novel tools can be used by companies that offer risk management in the form of insurance contracts.
