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.

Computer vision syndrome and associated factors in university students and teachers in Nampula, Mozambique.

BACKGROUND: Computer Vision Syndrome (CVS) is a complex of eye and visual problems that arise while using a computer or other Video Display Terminal (DVT). With the advent of the COVID-19 pandemic, the use of these DVTs has become indispensable in the lives of students and teachers. This study aims to identify the prevalence of CVS and associated factors in students and teachers at Lúrio University, in Nampula, during the pandemic period. METHODS: This is a cross-sectional study, carried out between November 2020 and March 2021. The validated CVS questionnaire (CVS-Q) and another semi-structured questionnaire on ergonomic risk factors were applied. Odds ratios (OR) and adjusted odds ratios (aOR) were calculated to measure the association between CVS and computer use conditions. RESULTS: The prevalence of CVS was 76.6%, and the female gender, age ≤ 20 years, levels I, II, III of course, lack of knowledge about ergonomics, use the computer to study, use more than 6 hours daily, absence of anti-reflex treatment, use of other devices and sitting in an inappropriate chair were risk factors for the occurrence of CVS, while being a teacher was a protective factor. CONCLUSION: The prevalence of CVS found in this study was high, due to several factors, especially not using ergonomic principles when using computers and other DVTs. There is a need to adopt intervention strategies focused on the most vulnerable groups such as women, age group ≤20 years and students, especially at the first year level, right after entering the University.

Analysis of bone cement distribution around fenestrated pedicle screws in low bone quality lumbosacral vertebrae.

PURPOSE: To study the exact distribution of bone cement around augmented fenestrated pedicle screws in both lumbar and sacral vertebrae of patients with low bone quality. METHODS: A total of 37 patients with instrumented lumbar fusion were investigated. 3D computed tomography virtual models of the injected cement and screws were obtained. The models were computed for their centroid (i.e. their average mass centre point), and their coordinates (x, y, z) were projected on their respective screw-transversal and screw-longitudinal planes for further analysis. RESULTS: The results showed better bone cement homogeneous distribution around the screws in lumbar (L4 and L5) than in sacral (S1) vertebrae. In the lumbar region, the centroids were transversally projected near the transversal centre of symmetry of the screws. On the other hand, in the sacral region, the cement flowed preferentially outside the centre of symmetry of the screws, into the sacral ala. CONCLUSIONS: The results confirm the different flow behaviours of bone cement in lumbar versus sacra vertebrae. The computer methodology followed in this study helps to understand the clinical monitoring observations and lays the foundations for better positioning of the screws and specific vertebrae-oriented screw designs.

A mobile insulator system to detect and disrupt cis-regulatory landscapes in vertebrates.

In multicellular organisms, cis-regulation controls gene expression in space and time. Despite the essential implication of cis-regulation in the development and evolution of organisms and in human diseases, our knowledge about regulatory sequences largely derives from analyzing their activity individually and outside their genomic context. Indeed, the contribution of these sequences to the expression of their target genes in their genomic context is still largely unknown. Here we present a novel genetic screen designed to visualize and interrupt gene regulatory landscapes in vertebrates. In this screen, based on the random insertion of an engineered Tol2 transposon carrying a strong insulator separating two fluorescent reporter genes, we isolated hundreds of zebrafish lines containing insertions that disrupt the cis-regulation of tissue-specific expressed genes. We therefore provide a new easy-to-handle tool that will help to disrupt and chart the regulatory activity spread through the vast noncoding regions of the vertebrate genome.

Presence of human papillomavirus DNA in breast cancer: a Spanish case-control study.

BACKGROUND: Breast cancer is one of the most important neoplasia among women. It was recently suggested that biological agents could be the etiological cause, particularly Human Papilloma Virus (HPV). The aim of this study was to explore the presence of HPV DNA in a case-control study. METHODS: We performed our study including 251 cases (breast cancer) and 186 controls (benign breast tumors), using three different molecular techniques with PCR (GP5/GP6, CLART® and DIRECT FLOW CHIP®). RESULTS: HPV DNA was evidenced in 51.8% of the cases and in 26.3% of the controls (p < 0.001). HPV-16 was the most prevalent serotype. The odds ratio (OR) of HPV within a multivariate model, taking into account age and breastfeeding, was 4.034. CONCLUSIONS: Our study, with methodological rigour and a sample size not previously found in the literature, demonstrate a significant presence of HPV DNA in breast cancer samples. A possible causal relationship, or mediation or not as a cofactor, remains to be established by future studies.

Validation of the Spanish version of Mackey childbirth satisfaction rating scale.

BACKGROUND: The "Mackey Childbirth Satisfaction Rating Scale" (MCSRS) is a complete non-validated scale which includes the most important factors associated with maternal satisfaction. Our primary purpose was to describe the internal structure of the scale and validate the reliability and validity of concept of its Spanish version MCSRS-E. METHODS: The MCSRS was translated into Spanish, back-translated and adapted to the Spanish population. It was then administered following a pilot test with women who met the study participant requirements. The scale structure was obtained by performing an exploratory factorial analysis using a sample of 304 women. The structures obtained were tested by conducting a confirmatory factorial analysis using a sample of 159 women. To test the validity of concept, the structure factors were correlated with expectations prior to childbirth experiences. McDonald's omegas were calculated for each model to establish the reliability of each factor. The study was carried out at four University Hospitals; Alicante, Elche, Torrevieja and Vinalopo Salud of Elche. The inclusion criteria were women aged 18-45 years old who had just delivered a singleton live baby at 38-42 weeks through vaginal delivery. Women who had difficulty speaking and understanding Spanish were excluded. RESULTS: The process generated 5 different possible internal structures in a nested model more consistent with the theory than other internal structures of the MCSRS applied hitherto. All of them had good levels of validation and reliability. CONCLUSIONS: This nested model to explain internal structure of MCSRS-E can accommodate different clinical practice scenarios better than the other structures applied to date, and it is a flexible tool which can be used to identify the aspects that should be changed to improve maternal satisfaction and hence maternal health.

Basin-scale phenology and effects of climate variability on global timing of initial seaward migration of Atlantic salmon (Salmo salar).

Migrations between different habitats are key events in the lives of many organisms. Such movements involve annually recurring travel over long distances usually triggered by seasonal changes in the environment. Often, the migration is associated with travel to or from reproduction areas to regions of growth. Young anadromous Atlantic salmon (Salmo salar) emigrate from freshwater nursery areas during spring and early summer to feed and grow in the North Atlantic Ocean. The transition from the freshwater ('parr') stage to the migratory stage where they descend streams and enter salt water ('smolt') is characterized by morphological, physiological and behavioural changes where the timing of this parr-smolt transition is cued by photoperiod and water temperature. Environmental conditions in the freshwater habitat control the downstream migration and contribute to within- and among-river variation in migratory timing. Moreover, the timing of the freshwater emigration has likely evolved to meet environmental conditions in the ocean as these affect growth and survival of the post-smolts. Using generalized additive mixed-effects modelling, we analysed spatio-temporal variations in the dates of downstream smolt migration in 67 rivers throughout the North Atlantic during the last five decades and found that migrations were earlier in populations in the east than the west. After accounting for this spatial effect, the initiation of the downstream migration among rivers was positively associated with freshwater temperatures, up to about 10 °C and levelling off at higher values, and with sea-surface temperatures. Earlier migration occurred when river discharge levels were low but increasing. On average, the initiation of the smolt seaward migration has occurred 2.5 days earlier per decade throughout the basin of the North Atlantic. This shift in phenology matches changes in air, river, and ocean temperatures, suggesting that Atlantic salmon emigration is responding to the current global climate changes.

Visual impairment and associated factors in adults from three suburban communities in Nampula, Mozambique.

CLINICAL RELEVANCE: Scientific evidence on the burden of visual impairment, its causes, and associated factors are essential to monitor progress in eye health, identify priorities and develop strategies and policies that meet the needs of the population, towards the eradication of preventable blindness. BACKGROUND: The aim of this study was to determine the prevalence of visual impairment, its causes and associated factors in adults living in suburban communities in Nampula. METHODS: This is a cross-sectional study conducted from November 2019 to February 2020. Eye examinations were performed on adults aged ≥18 years covered by the Lúrio University program, 'one student, one family'. The odds ratio (OR) and adjusted odds ratio (aOR) were calculated to study the association between the dependent variable (presenting visual impairment) and independent variables (gender, age, school level, residence, family income and systemic diseases), with a 95% confidence interval. RESULTS: Distance and near presenting visual impairment had a prevalence of 16.3% and 21.1%, respectively, and were statistically associated with the age groups between 45-65 (OR:4.9) and >65 years (OR: 29.1), illiterate (OR:13.8), primary (OR:4.8) and secondary (aOR:37.5) school level, farmer (OR:32.8) and retired (OR:14.3) occupation, and presence of systemic diseases (OR :3.3). The main causes of presenting visual impairment were uncorrected refractive error and cataract. CONCLUSION: The prevalence of presenting visual impairment is relatively high, given the enormous effort undertaken within the framework of VISION 2020: The Right to Sight global initiative. There is a need to develop intervention plans targeted at the highest risk groups, with a view to achieving the 'one student, one family' program goals with respect to eye health.

Dataset on the qualitative characteristics of roselle varieties (Hibiscus sabdariffa L.).

Roselle (Hibiscus sabdariffa L.) is a worldwide known species of great importance due to its medicinal properties and pleasant flavor. In Paraguay, it is used as an alternative crop by family-run farmers; however, the varieties used in the country are unknown, so no information is available on this crop. The qualitative characterization would collect knowledge serving as a basis for the registration of varieties produced in Paraguay. In addition, such data are useful for future genetic improvement programs considering this crop. The present work was carried out at the Multidisciplinary Center for Technological Research and the experimental farmland of the Faculty of Agricultural Sciences of the National University of Asuncion, during the years 2022 and 2023. The main objective was to carry out a morphological characterization of four Roselle varieties: Ana Delia, Benito, Dogo, and Creole. The design consisted of completely randomized blocks, with four treatments (varieties) and four replications; each experimental unit (block) was composed of 24 plants, distributed in four rows; 12 plants, selected from the central rows, were harvested for the evaluations. Stem color, leaf shape, leaf margin, rib color, petiole color, flower color, calyx color, calyx sepal opening, capsule shape, capsule color, capsule anthocyanin coloration, and pubescence level were evaluated. The results demonstrate qualitative differences between the varieties, which help to compare and classify them for a better variety selection.

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.

[Beliefs, attitudes and influence of the media in Spanish health care workers during the A (H1N1) 2009 flu pandemic]. / Creencias, actitudes e influencia de los medios de comunicación en trabajadores sanitarios españoles durante la gripe pandémica A (H1N1) 2009.

INTRODUCTION: The aim of this article is to report, from their own perspective, the attitudes and believes towards vaccination, with special emphasis on the influence of sources of information to make the decision to get vaccinated, of health care workers (HCWs), considered as a specific risk group for immunization strategy against A (H1N1) influenza. METHODS: Cross-sectional observational study focused on active health workers in the province of Alicante. Made by face to face questionnaires to a stratified random sample based on occupational categories in hospitals and health care centres. RESULTS: The sources of information differ between subgroups; physicians used journals and/or conferences, nurses obtained information through the Ministry of Health and other nurses, and the remaining workers opted for television and/or the family physician. Of the three studied groups, physicians felt minor concern about the influenza A (H1N1) pandemic (59.4%), had the most confidence in the vaccine (42.3%), were the ones who recommended the vaccine the most (44.4%), who best followed the recommendations to avoid infection (93%), and were the most vaccinated (18.3%). Around three-quarters (75.5%) of the HCWs assessed the provided information as fair, poor or very poor. All HCWs admitted that a social alarm was created. DISCUSSION: The success of future immunization campaigns against influenza in HCWs could increase if information activities were designed to focus on each subgroup of HCWs, by adapting the strategy and improving the quality of information.

[Validation of the questionnaire on vaccines and hesitancy to be vaccinated in the Spanish Society of Epidemiology]. / Validación del cuestionario sobre vacunas y reticencia a vacunarse en la Sociedad Española de Epidemiología.

OBJECTIVE: To develop and validate a survey aimed at epidemiologists to measure factors associated with vaccine reluctance. METHOD: Vaccination hesitancy refers to delayed acceptance or refusal of vaccination despite the availability of vaccination services. WHO included vaccination hesitancy among the 10 global health threats in 2019. Within this conceptual framework proposed by WHO, a committee of six experts from the Spanish Society of Epidemiology (SEE) designed a self-administered questionnaire to study factors associated with vaccination hesitancy in epidemiologists. This questionnaire was approved by the SEE Board, and was sent online to all members in 2019. Based on the responses obtained, the following characteristics were validated: face validity, internal validity, construct validity, criterion validity, reliability, as well as the characteristic curves of each item and the information function per item and overall. RESULTS: The final questionnaire showed two well-defined components, perception of vaccines and confidence in the transparency of vaccine data with high degrees of fit in all aspects of validation. Both components have shown that the higher the reluctance to vaccinate the better the questionnaire reports on these aspects. CONCLUSIONS: The study has allowed the development of a validated instrument in Spanish to measure the factors associated with vaccine reluctance among epidemiologists.

Feasibility of the set-up for the different approaches in robotic head and neck surgery with the Versius Surgical System.

The Versius Surgical System is a next generation soft-tissue robot with instrument and endoscope arms split into individual modules. Despite its similarities with previous systems, the basic changes in the design raise concerns relating to the feasibility of the set-up for the different approaches in robotic head and neck surgery procedures. We used a complete unit with a surgeon's console and four modules on a training mannequin to depict the different configurations in the operating room. We tested transoral robotic surgery and the four basic configurations for the remote access to the neck: transoral/transvestibular, retroauricular, axillary and bilateral axillo-breast approaches. We obtained a high quality simulation for transoral robotic surgery, as well as for the usual remote access approaches, except for the axillary approach. We were able to obtain an optimal distribution of the modules around the surgical table and an adequate configuration of the joints allowing the instruments to reach their targets. The Versius Surgical System might be an alternative device for robotic procedures in head and neck surgery, although this needs to be proved in a clinical setting.

[COVID-19 vaccination at the University of Alicante (Spain): detection of neutralizing antibodies against SARS-CoV-2 by rapid serological test, a cross-sectional study]. / Vacunación contra la COVID-19 en la Universidad de Alicante (España): detección de anticuerpos neutralizantes frente al sars-CoV-2 mediante test serológico rápido, un estudio transversal.

OBJECTIVE: Neutralizing antibodies against SARS-CoV-2 have shown to be an effective tool for the analysis of the immunity generated against COVID-19. Numerous seroprevalence studies carried out in different groups have made it possible to draw a global map of vaccination coverage through the use of rapid lateral flow immunochromatography serological tests for clinical and epidemiological purposes. The objective of our study was to determine the degree of immunity against SARS-CoV-2 associated with the presence of neutralizing antibodies in administrative staff, teachers and students at the University of Alicante by means of a rapid serological test and to learn about their experience with vaccination against COVID-19. METHODS: A cross-sectional epidemiological study was designed, based on the prevalence of antibodies against the S protein (spike) of SARS-CoV-2. A total of 888 people participated. The study was carried out with a single test (July 6 to July 22, 2021). Using logistic regression, adjusted Odds Ratios were calculated according to sex, age, type of vaccine, number of vaccine doses received, complete vaccination schedule, and having had COVID-19. RESULTS: The vaccines received mostly were Vaxzevria® and Comirnaty®, with 73.3% between both, although 67.2% presented a complete regimen. The results of the OJABIO rapid neutralizing antibody test gave a positive result in 61.4% of the sample. There was a high association between the variables COVID-19 infection, two doses of vaccine, Spikevax® or Comirnaty® vaccine, and eighteen/twenty-nine years old group with a positive result on the OJABIO test. A total of 712 subjects answered the parallel survey (80%) on adverse effects and preferences between the different vaccines against COVID-19. CONCLUSIONS: The vaccination status against COVID-19 in the university community after six months of the start of national immunization strategies reflects low coverage despite the excellent willingness to get vaccinated. Neutralizing antibodies (NAb) rapid tests can be useful to guide immunization strategies and decide when to administer new booster doses.

OBJECTIVE: Los anticuerpos neutralizantes frente al SARS-CoV-2 han resultado una herramienta eficaz para el análisis de la inmunidad generada frente a la COVID-19. Numerosos estudios de seroprevalencia realizados en diferentes colectivos han permitido trazar un mapa global sobre la cobertura vacunal mediante el uso de pruebas serológicas rápidas de inmunocromatografía de flujo lateral con fines clínicos y epidemiológicos. El objetivo de nuestro estudio fue determinar el grado de inmunidad frente al SARS-CoV-2 asociado a la presencia de anticuerpos neutralizantes en personal administrativo, docentes y estudiantes de la Universidad de Alicante, mediante un test serológico rápido, así como conocer su experiencia sobre la vacunación frente a la COVID-19. METHODS: Se diseñó un estudio epidemiológico, transversal, basado en la prevalencia de anticuerpos frente a la proteína S (espícula o Spike) del SARS-CoV-2. Participaron un total de 888 personas. El estudio se llevó a cabo con un único test (6 de julio a 22 de julio de 2021). Mediante regresión logística se calcularon Odds Ratios ajustadas según sexo, edad, tipo de vacuna, número de dosis de vacuna recibidas, pauta completa de vacunación y haber padecido la COVID-19. RESULTS: Las vacunas recibidas mayoritariamente fueron Vaxzevria® y Comirnaty®, con un 73,3% entre ambas; el 67,2% presentó pauta completa. Los resultados del test rápido de anticuerpos neutralizantes OJABIO dieron un resultado positivo en el 61,4% de la muestra. La posibilidad de un resultado positivo en el test OJABIO estuvo fuertemente asociada a haber padecido la COVID-19, haber recibido dos dosis, estar vacunado con Spikevax® o Comirnaty® o pertenecer al grupo de dieciocho a veintinueve años. Un total de 712 sujetos respondieron a un cuestionario (80%) paralelo sobre los efectos adversos y las preferencias entre las distintas vacunas contra la COVID-19. CONCLUSIONS: El estado de vacunación frente a la COVID-19 en la comunidad universitaria a los seis meses de la puesta en marcha de las estrategias nacionales de inmunización refleja una baja cobertura asociada, a pesar de la excelente predisposición a vacunarse. Los test rápidos de anticuerpos neutralizantes (AcN) pueden ser de utilidad para orientar las estrategias de inmunización y para decidir el momento de administrar nuevas dosis de refuerzo.

[Health risk behaviors by occupation in working population in Spain]. / Conductas de riesgo para la salud según la ocupación en población empleada en España.

OBJECTIVE: This study aims to analyze the variations in the prevalence of different health risk behaviors according to occupation in working population in Spain. METHOD: Cross-sectional study with data from the Spanish National Health Survey of 2017. The analysis includes adults between 18 and 65 years with employment at the time of the survey. Health risk behaviors are obesity, physical inactivity in free time, tobacco consumption and excessive alcohol consumption. The primary explanatory variable is the occupation, using the National Classification of Occupations of 2011. Sociodemographic characteristics are gender, age, country of birth and educational level. The prevalences (P) of risk behaviors have been calculated, as well as the odd and adjusted odds ratios (aOR). RESULTS: The highest figures of obesity are observed in operators of installations and machinery and assemblers (P: 20.0%; ORa: 1.26; A95%CI: 1.04-1.52). The higher level of physical inactivity during free time appears in elementary occupations (P: 83.4%; ORa: 1.70; A95%CI: 1.45-1.99). Tobacco consumption is higher in operators of installations and machinery and assemblies (P: 37.4%; ORa: 1.22; A95%CI: 1.05-1.43). Excessive alcohol consumption appears to a greater extent on skilled workers in the agricultural sector, livestock, forestry and fisheries (P: 3.9%; ORa: 1.51; A95%CI: 0.83-2.75). CONCLUSIONS: The results indicate a greater relationship between risk behaviors for health and manual or lower-skilled occupations.

Sustainable and Nutritional Recommendations for the Development of Menus by School Food Services in Spain.

BACKGROUND: Recommendations for the development of school menus can promote healthier, more sustainable food systems. In Spain, these recommendations depend on regional governments (Autonomous Communities-CCAAs) that develop their own guides. The objective of this study was to explore the nutritional and sustainability recommendations for the development of menus by school food services in Spain. METHODS: Guides were reviewed that were available on the official web pages of the councils of health and education. Twenty-four variables were studied and organized into three categories: characteristics, nutritional recommendations and sustainability. The number of recommendations included in each guide was counted. The weekly frequency of the suggested food provision for each food group was calculated, as was the average, median, standard deviation, confidence interval and interquartile index. RESULTS: Overall, 13 guides were reviewed from different CCAAs. All of them included at least three of the nutritional recommendations, two suggested restrictions in the provision of foods with high quantities of salt and six suggested restrictions in foods with high levels of trans and saturated fats and sugars. All except one guide recommended the weekly provision of foods by food group: protein-rich foods (n = 8), cereals and root vegetables (n = 6), vegetables (n = 5.2) and fruit (n = 4.3). Of the eight criteria for sustainability studied, nine guides included one or none. CONCLUSIONS: Guides for the provision of meals at school in Spain promote the incorporation of healthy foods; however, they rarely restrict foods with high levels of fat, salt and sugar, and the promotion of food sustainability is only just beginning. These guides should be reviewed and updated to include recommendations that promote healthy and sustainable food systems.

School Fruit and Vegetables Scheme: Characteristics of Its Implementation in the European Union from 2009/10 to 2016/17.

The "School Fruit and Vegetables Scheme" (SFVS) was proposed in 2009/10 as a strategy to support the consumption of Fruit and Vegetables (FV), decrease rates of obesity, improve agricultural income, stabilize markets, and ensure the current and future supply of these foods. However, there is little information about how it was carried out in the EU. Given the potential of the SFVS to support healthier, more sustainable food systems, the objective of this study was to identify the characteristics of SFVS implementation from 2009/10 to 2016/17 in the EU. A longitudinal, observational, and retrospective study was carried out based on secondary data. A total of 186 annual reports of the Member States (MS) participating in the SFVS from 2009/10 to 2016/17 were consulted: European and national budget, funds used from the EU, participating schools and students, duration of the SFVS, FV offered, and application of sustainability criteria, expenditure per student, days of the week, the quantity of FV offered per student and other indicators were calculated. The majority of MS participated in the SFVS during the study period with a heterogeneous implementation pattern in terms of funds used, coverage, duration, quantity (totals and by portion), and cost of FV distributed per student. The sustainability criteria for the FV distribution were also not applied uniformly in all the MS. Establishing minimum recommendations for SFVS implementation are recommended to maximize the benefits of the SFVS. The results may be useful for planning new strategies to help address and improve current health and environmental problems.

Feeding Difficulties Associated with IBD during the Working Day: Qualitative Study, Alicante Spain.

Inflammatory bowel disease (IBD) is a chronic disease characterized by inflammation of the gastrointestinal tract. Nutrition is a key aspect as it can modulate much of the symptomatology. People affected by IBD often experience difficulties at work in all areas, including adapting their dietary management to workplace situations. The aim of this study is to identify the difficulties associated with eating during the working day in people diagnosed with IBD. A qualitative study was conducted through a nominal and focus group with people affected by IBD. After the thematic analysis of the data, three main themes emerged: management of food during the working day, searching for strategies to live with the disease, and the importance of visibility and support. This study shows that IBD influences the working life of people with IBD and makes it difficult to maintain an adequate diet. The institutions in charge of the treatment of IBD patients should consider the support of multidisciplinary teams, including nutrition professionals, as a fundamental part of the pathology control and dietary treatment to minimize its repercussions at work.

[CVS-Q teen©: computer vision syndrome in adolescents and its relationship with digital textbooks]. / CVS-Q teen©: síndrome visual informático en adolescentes y su relación con libros de texto digitales.

OBJECTIVE: To analyse the prevalence and progression of computer vision syndrome in secondary and high school students with the CVS-Q© adapted and validated for adolescents, depending on whether they use textbooks or digital books. METHOD: The CVS-Q© will be adapted by a pilot study in adolescents and a nominal group of visual health specialists, teachers and parents. The resulting version (CVS-Q teen©) will be tested to confirm its quality and applicability and a validation study will be done with visual tests, retest and psychometric analysis. Subsequently, a prospective longitudinal study with four repeated measures will be carried out in adolescents from two secondary schools of San Juan de Alicante (one has replaced textbooks by tablets). Computer vision syndrome will be measured by the CVS-Q teen© with three follow-ups. The prevalence of computer vision syndrome will be analysed according to sociodemographic, visual and digital device use variables. Logistic regression models will be performed, with random effect by student and time of use.

Barriers to Accessing Eye Health Services in Suburban Communities in Nampula, Mozambique.

Globally, an estimated 2.2 billion people are visually impaired (VI) or blind, and a large proportion (90%) of those affected live in low- and middle-income countries (LMICs), where access to eye health services is limited. This study aimed to identify barriers to accessing eye health services and associated factors in suburban communities of Nampula. A cross-sectional community-based study was carried out on adults ≥18 years old. A total of 338 adults were randomly selected from three communities (Muthita, Piloto, and Nthotta). Individual interviews were carried out and socio-demographic data, eye symptoms, date of last eye examination, and barriers to access to eye health services were extracted. Among participants, 49.4% had eye symptoms and 41.7% did not have their eye examinations up to date. The most cited barriers were crowding in hospitals (40.7%), financial difficulties (30.0%), self-medication (20.5%), traditional treatment (17.8%), and buying eyeglasses on the street (11.6%). Barriers limited the service target to 33%. Lower levels of schooling and monthly family income and farmer occupation were statistically associated with the most barriers as risk factors. The use of eye health services was lower due to barriers to accessing eye services. More specific intervention plans and greater cooperation between sectors are needed to improve these indicators.
