Assessment of cataract surgery outcomes in Nampula (Mozambique): visual acuity, visual function and quality of life.

BACKGROUND: Despite advances in surgical techniques, cataract remains the leading cause of preventable blindness, and massive surgeries have been adopted as a strategy to change this situation. Monitoring the results of cataract surgeries has become imperative to ensure their quality. Therefore, this study aims to assess the cataract surgery outcomes performed at the Central Hospital of Nampula Mozambique. METHODS: This is a prospective and longitudinal study in which translation, cultural adaptation and validation of the visual function (VF) and quality of life (QoL) questionnaire were performed. The appearance, content, construct, criterion, internal consistency and responsiveness were validated using the most common methods and indicators. Visual acuity (VA), VF and QoL were evaluated on 447 patients before and after surgery by t-test and effect sizes. RESULTS: VF and QoL questionnaires showed one-dimension, good values of TLI (0.973, 0.951) and SRMR (0.057, 0.054), and for each item, weights > 0.7, H2 > 0.5, ranges > 5.8 and the RMSEA < 0.08. Correlations for criterion validity were high and for responsiveness were high for QoL and moderate for VF one and the ordinal Cronbach's alpha coefficients were greater than 0.97. Difference between VA, VF and QoL before and after surgery was statistically significant (p < 0.001). After surgery, 74.3% of patients had good, 23.5% had borderline and 2.2% had poor VA. CONCLUSIONS: The cataract surgery outcomes are outside the WHO recommendations regarding VA, but they have had a great impact on improving VF and QoL. The questionnaires showed excellent psychometric properties and should be used in daily clinical practice to evaluate the results of cataract surgeries.

The Design and Development of Recycled Concretes in a Circular Economy Using Mixed Construction and Demolition Waste.

This research study analysed the effect of adding fine-fMRA (0.25% and 50%)-and coarse-cMRA (0%, 25% and 50%)-mixed recycled aggregate both individually and simultaneously in the development of sustainable recycled concretes that require a lower consumption of natural resources. For this purpose, we first conducted a physical and mechanical characterisation of the new recycled raw materials and then analysed the effect of its addition on fresh and hardened new concretes. The results highlight that the addition of fMRA and/or cMRA does not cause a loss of workability in the new concrete but does increase the amount of entrained air. Regarding compressive strength, we observed that fMRA and/or cMRA cause a maximum increase of +12.4% compared with conventional concrete. Tensile strength increases with the addition of fMRA (between 8.7% and 5.5%) and decreases with the use of either cMRA or fMRA + cMRA (between 4.6% and 7%). The addition of fMRA mitigates the adverse effect that using cMRA has on tensile strength. Regarding watertightness, all designed concretes have a structure that is impermeable to water. Lastly, the results show the feasibility of using these concretes to design elements with a characteristic strength of 25 MPa and that the optimal percentage of fMRA replacement is 25%.

A Temperature Conditioned Markov Chain Model for Predicting the Dynamics of Mosquito Vectors of Disease.

Understanding and predicting mosquito population dynamics is crucial for gaining insight into the abundance of arthropod disease vectors and for the design of effective vector control strategies. In this work, a climate-conditioned Markov chain (CMC) model was developed and applied for the first time to predict the dynamics of vectors of important medical diseases. Temporal changes in mosquito population profiles were generated to simulate the probabilities of a high population impact. The simulated transition probabilities of the mosquito populations achieved from the trained model are very near to the observed data transitions that have been used to parameterize and validate the model. Thus, the CMC model satisfactorily describes the temporal evolution of the mosquito population process. In general, our numerical results, when temperature is considered as the driver of change, indicate that it is more likely for the population system to move into a state of high population level when the former is a state of a lower population level than the opposite. Field data on frequencies of successive mosquito population levels, which were not used for the data inferred MC modeling, were assembled to obtain an empirical intensity transition matrix and the frequencies observed. Our findings match to a certain degree the empirical results in which the probabilities follow analogous patterns while no significant differences were observed between the transition matrices of the CMC model and the validation data (ChiSq = 14.58013, df = 24, p = 0.9324451). The proposed modeling approach is a valuable eco-epidemiological study. Moreover, compared to traditional Markov chains, the benefit of the current CMC model is that it takes into account the stochastic conditional properties of ecological-related climate variables. The current modeling approach could save costs and time in establishing vector eradication programs and mosquito surveillance programs.

Acceptability of Violence Against Women Among the Roma Population in Spain.

Acceptability of violence against women (VAW) is a key dimension in addressing this social problem, given its influence on both the violent conduct of aggressors and the decisions of affected women. This study analyzes, for the first time, the magnitude of acceptability of VAW and associated factors in the Roma population in Spain. The Roma population is the largest ethnocultural minority in Europe. Data were analyzed from the Spanish National Health Survey of the Roma Population of 2014, a survey of 1,167 people identified as members of the Roma community. The results indicate that 70.9% of those surveyed completely reject VAW, with lower probability of acceptability among women than men (odds ratio [OR]: 0.66; 95% confidence interval [CI]: [0.51, 0.86]). There is also a decrease in probability as income increases, in people who identify themselves as evangelical (OR: 0.5; 95% CI: [0.36, 0.71]) and among those who report being acquainted with a battered woman (OR: 0.68; 95% CI: [0.48, 0.97]), similarly in women and men. It has to be highlighted that the observed associations between socioeconomic conditions and acceptability of VAW should be considered when designing strategies for raising awareness about the consequences of VAW for the Roma population.

Differences in the Prevalence of Fruit and Vegetable Consumption in Spanish Workers.

The present study aims to examine the differences in daily fruit and vegetable consumption in the working population in Spain. A cross-sectional study was conducted, using data from the 2017 National Health Survey (n = 10,700 workers aged between 18 and 65 years). The daily consumption of fruit and vegetables was evaluated using two items included in a food frequency questionnaire. Occupations were classified into the 17 main groups of the National Classification of Occupations of 2011 (CNO-11). The prevalence (P) of daily fruit and vegetable consumption was calculated in relation to sociodemographic characteristics, health behaviors, work-related characteristics and occupations. Logistic regression analysis was performed to examine the association, with simple and adjusted Odds Ratio (aOR). The P of daily consumption of fruit and vegetables in workers was 60% for fruit and 40% for vegetables. After adjusting for sociodemographic characteristics and health behaviors, workers working night or rotating shifts had a lower consumption of fruits (aOR:0.9; p < 0.05), and those working on temporary contracts had a lower consumption of vegetables (aOR:0.8; p < 0.05). Engineers, scientists, health care workers and teachers had the highest fruit consumption (74.5%) and the highest vegetable consumption (55.1%). The lowest consumption of fruits was presented by the military (42.3%) and unskilled workers in the service sector (45.8%), and the lowest consumption of vegetables was presented by skilled construction workers (25.5%). These findings could aid in workplace health promotion and could be used in future studies to evaluate the impact of the activities adopted.

Changes in Socioeconomic Inequalities in Amenable Mortality after the Economic Crisis in Cities of the Spanish Mediterranean Coast.

Several studies have described a decreasing trend in amenable mortality, as well as the existence of socioeconomic inequalities that affect it. However, their evolution, particularly in small urban areas, has largely been overlooked. The aim of this study is to analyse the socioeconomic inequalities in amenable mortality in three cities of the Valencian Community, namely, Alicante, Castellon, and Valencia, as well as their evolution before and after the start of the economic crisis (2000-2007 and 2008-2015). The units of analysis have been the census tracts and a deprivation index has been calculated to classify them according to their level of socioeconomic deprivation. Deaths and population were also grouped by sex, age group, period, and five levels of deprivation. The specific rates by sex, age group, deprivation level, and period were calculated for the total number of deaths due to all causes and amenable mortality and Poisson regression models were adjusted in order to estimate the relative risk. This study confirms that the inequalities between areas of greater and lesser deprivation in both all-cause mortality and amenable mortality persisted along the two study periods in the three cities. It also shows that these inequalities appear with greater risk of death in the areas of greatest deprivation, although not uniformly. In general, the risks of death from all causes and amenable mortality have decreased significantly from one period to the other, although not in all the groups studied. The evolution of death risks from before the onset of the crisis to the period after presented, overall, a general pro-cyclical trend. However, there are population subgroups for which the trend was counter-cyclical. The use of the deprivation index has made it possible to identify specific geographical areas with vulnerable populations in all three cities and, at the same time, to identify the change in the level of deprivation (ascending or descending) of the geographical areas throughout the two periods. It is precisely these areas where more attention is needed in order to reduce inequalities.

Inequalities in the use of gynecological visits and preventive services for breast and cervical cancer in Roma women in Spain.

OBJECTIVES: The Roma population in Spain makes up about two percent of the population and has worse health indicators than the general population. We analyzed both populations in 2006 and 2014 to discover whether there are differences in terms of gynecological visits and preventive services for breast and cervical cancer in Spain. METHODS: Cross-sectional study is based on the Spanish National Health Survey (SNHS) of 2006 and 2012 and the National Health Survey of the Roma Population (NHSRP) of 2006 and 2014. RESULTS: Roma women used gynecological visits less than the general population in 2006 (ORa 0.5 [0.4; 0.6] and in 2014 (ORa 0.2 [0.2; 0.3)]. In addition, use of the mammogram was lower in Roma women (ORa 0.7 [0.6; 0.8]), especially in the ages of the screening tests, and they had lower probability of receiving cervical examinations in 2006 (ORa 0.5 [0.4; 0.6]) and in 2014 (ORa 0.7 [0.6; 0.9]). CONCLUSIONS: This study shows that the inequality gap in gynecological visits and preventive services for breast and cervical cancer in Roma women has persisted during the years studied (2006 and 2014), despite Spanish prevention policies.

[Assessment of the consensus document on food in educational centres to evaluate school menus]. / Valoración del documento de consenso sobre alimentación en centros educativos para evaluar menús escolares.

OBJECTIVE: To explore the applicability of the Consensus Document on School Food Programmes in Educational Centres (DCSECE) to evaluate the adaptation of school menus to healthy eating recommendations. METHOD: Transversal study that analyzes monthly school menus from 28 early-childhood education and primary education centres in Andalusia and Canary Islands (Spain). Data were collected using an ad-hoc protocol based on the DCSECE recommendations and divided into food categories and subcategories. We studied the weekly menu offering of each of the foods by category and subcategory and compared them to the DCSECE recommendations. RESULTS: The majority of the schools offered better meals than as specified by the recommendations, in terms of vegetables, other garnishes and other deserts. They offered poorer quality meals in the categories of rice, pasta, prepared foods and salads, and had an equivalent offering in terms of pulses, meats, fish and eggs. By subcategory, we observed the predominance of cooked vegetables in the vegetable category as compared to salads, and the predominance of processed meats in the meats category. CONCLUSIONS: The DCSECE could be a useful instrument for evaluating the nutritional offering of school menus. However, there is a need for greater specificity in the recommendations, in order to identify whether these menus adhere to healthy eating recommendations.

Smoking Prevalence Inequalities Among Roma and Non-Roma Population in Spain Between 2006 and 2014.

Tobacco consumption is unequally distributed in society. The objective was to identify trends in tobacco use among the General and Spanish Roma populations in 2006 and 2014, years characterized by strengthening of anti-smoking policy in Spain. We calculated prevalences and logistical regression models based on the Spanish National Health Survey (2006/2012) and the National Health Survey of the Roma population (2006/2014). Smoking decreased only in men in the General population (OR 0.885). In the Roma population, there were no significant changes observed for the 2 years studied (OR: men 1.095, and women 1.147). In fact, Roma men smoke 4.2 cigarettes more, and they have a younger age of initial tobacco use. Smoking behavior of the Roma population has not changed, and there has been no reduction in inequalities in tobacco use among the two populations, despite public policies designed to reduce tobacco use in Spain.

Economic Crisis and Amenable Mortality in Spain.

Background: Both overall mortality and avoidable mortality have decreased in recent years in most European countries. It has become clear that less privileged socioeconomic groups have an increased risk of death. In 2008, most countries went into a severe economic recession, whose effects on the health of the population are still ongoing. While on the one hand, some evidence associates the economic crisis with positive health outcomes (pro-cyclical effect), on the other hand, some other evidence suggests that the economic crisis may pose serious public health problems (counter-cyclical effect), which has given rise to controversy. Objectives: To describe the evolution of overall mortality and amenable mortality in Spain between 2002⁻2007 (before the economic crisis) and 2008⁻2013 (during the economic crisis), nationally and by province, as well as to analyse trends in the risks of death and their association with indicators of the impact of the crisis. Methods: Ecological study of overall mortality and amenable mortality describing the evolution of the risks of death between 2002⁻2007 and 2008⁻2013. Age Standardised Rates were calculated, as well as their percentage change between periods. The association between percentage changes and provincial indicators of the impact of the crisis was analysed. Amenable mortality was studied both overall and categorised into five groups. Results: Amenable mortality represented 8.25% of overall mortality in 2002⁻2007, and 6.93% in 2008⁻2013. Age Standardised Rates for overall mortality and global amenable mortality generally declined, with the sharpest decline in amenable mortality. Decreases in overall mortality and amenable mortality were directly related to vulnerability indicators. The most significant decreases were registered in ischaemic heart disease, cerebrovascular disease, and other amenable causes. The relationship with vulnerability indices varied from direct (cancer) to inverse (hypertensive disease). Conclusions: Amenable mortality shows a more significant decrease than overall mortality between both study periods, albeit unevenly between provinces causes of death. Higher vulnerability indicators entail greater declines, although this trend varied for different causes. Mortality trends and their relationship with socioeconomic indicators in a situation of crisis must be conducted cautiously, taking into consideration a possible pro-cyclical effect.

[Purchase of local foods for school meals in Andalusia, the Canary Islands and the Principality of Asturias (Spain)]. / Compra de alimentos de proximidad en los comedores escolares de Andalucía, Canarias y Principado de Asturias.

OBJECTIVE: To explore and compare the characteristics of Primary Education Centres (PEC) in Andalusia, the Canary Islands and the Principality of Asturias depending on whether or not they make local food purchases (LFP) for school meals and to explore the opinion of cafeteria managers about the benefits and challenges of this type of purchase. METHOD: Information on the characteristics of 186 PECs and opinions of cafeteria managers about the benefits/challenges of LFP was collected through an electronic questionnaire. Data were stratified according to how the products were purchased (LFP: yes/no), and the chi square test was applied. RESULTS: 38.2% of the PECs studied make LFP. This is more frequent in rural areas (51.0 with self-managed cafeterias (80.0%), and their own kitchen (65.5%). These centres have less expensive menus than their peers (69.8%), participate more frequently in healthy eating programmes (81.5%) and purchase more organic food products (65.8%). According to the majority of the participants whose centres engage in LFP, the benefits include: supporting the local economy (97.2%), the offer of fresh foods (97.2%) and environmental sustainability (93.0%). The challenges include: productive capacity of the region (50.7%), the seasonal variation in food production (71.8%), and the lack of support (42.3%) and information from the government (46.5%). CONCLUSION: The location of the centres, the management of the cafeteria and the availability of a kitchen on site can influence the development of LFP in schools. Government support could help to integrate LFP in schools, improving school meals at a lower economic and environmental cost.

[Local food production for school feeding programmes in Spain]. / Alimentos de producción local en los comedores escolares de España.

OBJECTIVE: To identify and characterize initiatives that promote the purchase of locally-sourced foods to supply schools and the school centres carrying out the initiatives. METHOD: Exploratory, descriptive study based on secondary data and key informant reports. A search of governmental and non-governmental initiatives was carried out at the autonomous community level. Government initiatives were located through school feeding programmes in the different autonomous communities, their nutritional guides and representatives of the councils for education and agriculture. Non-governmental initiatives were found through their own websites and the snowball technique. Initiatives were analysed by their geographic distribution, organizational area (government vs. non-government), number of school centres carrying out the initiatives, management style and organic food purchase. A descriptive analysis of the data was carried out. RESULTS: 12 initiatives carried out by 318 schools (2.16% of all the schools with food service in Spain) were identified. Among these, 6 are governmental initiatives with a scope of 274 schools (1.86%), and 6 are non-governmental initiatives with a scope of 44 schools (0.30%). Most of these schools have a public management system in place (n=284). All the initiatives provide for the purchase of organic food. CONCLUSION: Local food purchase initiatives in Spain have a limited reach. However, the existence of a state directive could support and strengthen the development of such initiatives, given that school commitment is greater when initiatives are driven by the public sector.

Acceptability of pandemic A(H1N1) influenza vaccination by Essential Community Workers in 2010 Alicante (Spain), perceived seriousness and sources of information.

OBJECTIVE: Describe acceptability of pandemic A(H1N1) influenza vaccination by Essential Community Workers (ECWs) from Alicante province (Spain) in January 2010. Evaluate the correlation with attitudes, beliefs, professional advice and information broadcasted by media. METHOD: In this cross-sectional study, face-to-face interviews were conducted with 742 ECWs to assess their attitudes towards vaccination against the pandemic influenza strain. A multivariable regression model was made to adjust the Odds Ratios (ORs). RESULTS: Some ECWs reported having been vaccinated with seasonal vaccine, 21.5% (95%IC 18.6-24.9); only 15.4% (95%IC 12.8-18.4) with the pandemic one. ECWs vaccinated regularly against seasonal flu (OR 5.1; 95%IC 2.9-9.1), those who considered pandemic influenza as a severe or more serious disease than seasonal flu (OR 3.8; 95%IC 2.1-6.7) and those who never had doubts about vaccine safety (OR 3.7; 95%IC2.1-6.7) had a better acceptance of pandemic vaccine. Finally, 78.7% (95%IC 75.1-81.4) had doubts about pandemic vaccine's effectiveness. CONCLUSION: The vast amount of information provided by the media did not seem to be decisive to prevent doubts or to improve the acceptability of the vaccine in ECWs. Professional advice should be the focus of interest in future influenza vaccination campaigns. These results should be taken into account by health authorities.
