Characterization of the degree of food processing in the European Prospective Investigation into Cancer and Nutrition: Application of the Nova classification and validation using selected biomarkers of food processing
Background: Epidemiological studies have demonstrated an association
between the degree of food processing in our diet and the risk of various
chronic diseases. Much of this evidence is based on the international Nova
classification system, which classifies food into four groups based on the type
of processing: (1) Unprocessed and minimally processed foods, (2) Processed
culinary ingredients, (3) Processed foods, and (4) “Ultra-processed” foods
(UPF). The ability of the Nova classification to accurately characterise the
degree of food processing across consumption patterns in various European
populations has not been investigated so far. Therefore, we applied the Nova
coding to data from the European Prospective Investigation into Cancer and
Nutrition (EPIC) in order to characterize the degree of food processing in our
diet across European populations with diverse cultural and socio-economic
backgrounds and to validate this Nova classification through comparison with
objective biomarker measurements.
Methods: After grouping foods in the EPIC dataset according to the Nova
classification, a total of 476,768 participants in the EPIC cohort (71.5% women;
mean age 51 [standard deviation (SD) 9.93]; median age 52 [percentile (p)25–
p75: 58–66] years) were included in the cross-sectional analysis that
characterised consumption patterns based on the Nova classification. The
consumption of food products classified as different Nova categories were
compared to relevant circulating biomarkers denoting food processing,
measured in various subsamples (N between 417 and 9,460) within the EPIC
cohort via (partial) correlation analyses (unadjusted and adjusted by sex,
age, BMI and country). These biomarkers included an industrial transfatty
acid (ITFA) isomer (elaidic acid; exogenous fatty acid generated during
oil hydrogenation and heating) and urinary 4-methyl syringol sulfate (an
indicator for the consumption of smoked food and a component of liquid
smoke used in UPF). Results: Contributions of UPF intake to the overall diet in % grams/day varied
across countries from 7% (France) to 23% (Norway) and their contributions to
overall % energy intake from 16% (Spain and Italy) to >45% (in the UK and
Norway). Differences were also found between sociodemographic groups;
participants in the highest fourth of UPF consumption tended to be younger,
taller, less educated, current smokers, more physically active, have a higher
reported intake of energy and lower reported intake of alcohol. The UPF
pattern as defined based on the Nova classification (group 4;% kcal/day) was
positively associated with blood levels of industrial elaidic acid (r = 0.54) and
4-methyl syringol sulfate (r = 0.43). Associations for the other 3 Nova groups
with these food processing biomarkers were either inverse or non-significant
(e.g., for unprocessed and minimally processed foods these correlations were
–0.07 and –0.37 for elaidic acid and 4-methyl syringol sulfate, respectively).
Conclusion: These results, based on a large pan-European cohort,
demonstrate sociodemographic and geographical differences in the
consumption of UPF. Furthermore, these results suggest that the Nova
classification can accurately capture consumption of UPF, reflected by
stronger correlations with circulating levels of industrial elaidic acid and a
syringol metabolite compared to diets high in minimally processed foods.International Agency for Research on Cancer (IARC)Imperial College LondonNIHR

Safeguarding Health at the Workplace: A Study of Work Engagement, Authenticity and Subjective Wellbeing among Religious Workers
: Research in work and organizational psychology has paid little attention to religious workers, something certainly surprising as faith-based organizations play a key role in the welfare state of many countries. This research shows that religious workers in a Catholic order present a high degree of subjective wellbeing, both in terms of flourishing and satisfaction with life in general,
and a positive balance of positive and negative feelings. More specifically, this study examines the relationship between authenticity and wellbeing amongst religious workers. Survey responses from 142 religious workers in Spain were analyzed using partial least squares path modelling. The results reveal that subjective wellbeing at work is positively related to authenticity. In addition, this relationship is mediated by their level of work engagement

Self-reported adherence to the Mediterranean diet has been modestly inversely associated with incidence of type 2 diabetes (T2D) in cohort studies. There is uncertainty about the validity and magnitude of this association due to subjective reporting of diet. The association has not been evaluated using an objectively measured biomarker of the Mediterranean diet.
Methods and findings
We derived a biomarker score based on 5 circulating carotenoids and 24 fatty acids that discriminated between the Mediterranean or habitual diet arms of a parallel design, 6-month partial-feeding randomised controlled trial (RCT) conducted between 2013 and 2014, the MedLey trial (128 participants out of 166 randomised). We applied this biomarker score in an observational study, the European Prospective Investigation into Cancer and Nutrition (EPIC)-InterAct case-cohort study, to assess the association of the score with T2D incidence over an average of 9.7 years of follow-up since the baseline (1991 to 1998). We included 22,202 participants, of whom 9,453 were T2D cases, with relevant biomarkers from an original case-cohort of 27,779 participants sampled from a cohort of 340,234 people. As a secondary measure of the Mediterranean diet, we used a score estimated from dietary-self report. Within the trial, the biomarker score discriminated well between the 2 arms; the cross-validated C-statistic was 0.88 (95% confidence interval (CI) 0.82 to 0.94). The score was inversely associated with incident T2D in EPIC-InterAct: the hazard ratio (HR) per standard deviation of the score was 0.71 (95% CI: 0.65 to 0.77) following adjustment for sociodemographic, lifestyle and medical factors, and adiposity. In comparison, the HR per standard deviation of the self-reported Mediterranean diet was 0.90 (95% CI: 0.86 to 0.95). Assuming the score was causally associated with T2D, higher adherence to the Mediterranean diet in Western European adults by 10 percentiles of the score was estimated to reduce the incidence of T2D by 11% (95% CI: 7% to 14%). The study limitations included potential measurement error in nutritional biomarkers, unclear specificity of the biomarker score to the Mediterranean diet, and possible residual confounding.
Conclusions
These findings suggest that objectively assessed adherence to the Mediterranean diet is associated with lower risk of T2D and that even modestly higher adherence may have the potential to reduce the population burden of T2D meaningfully.EU FP6 programme

Dietary Intake of 91 Individual Polyphenols and 5-Year Body Weight Change in the EPIC-PANACEA Cohort
Polyphenols are bioactive compounds from plants with antioxidant properties that may have a protective role against body weight gain, with adipose tissue and systemic oxidative stress as potential targets. We aimed to investigate the dietary intake of individual polyphenols and their association with 5-year body weight change in a sub-cohort of the European Prospective Investigation into Cancer and Nutrition (EPIC). This study included 349,165 adult participants from nine European countries. Polyphenol intake was estimated through country-specific validated dietary questionnaires and the Phenol-Explorer database. Body weight was obtained at recruitment and after a mean follow-up time of 5 years. Associations were estimated using multilevel mixed linear regression models. From 91 polyphenols included, the majority (n = 67) were inversely associated with 5-year body weight change after FDR-correction (q < 0.05). The greatest inverse associations were observed for quercetin 3-O-rhamnoside (change in weight for doubling in intake: -0.071 (95% CI: -0.085; -0.056) kg/5 years). Only 13 polyphenols showed positive associations with body weight gain, mainly from the subclass hydroxycinnamic acids (HCAs) with coffee as the main dietary source, such as 4-caffeoylquinic acid (0.029 (95% CI: 0.021; 0.038) kg/5 years). Individual polyphenols with fruit, tea, cocoa and whole grain cereals as the main dietary sources may contribute to body weight maintenance in adults. Individual HCAs may have different roles in body weight change depending on their dietary source.Instituto De Salud Carlos III (European Regional Development Fund, ERDF, a way to build Europe)

The Subjective Well-Being Challenge in the Accounting Profession: The Role of Job Resources
The main activity of the accountant is the preparation and audit of the financial information of a company. The subjective well-being of the accountant is important to ensure a balanced professional judgment and to offer a positive image of the profession in the face of the incorporation and retention of talent. However, accountants are subjected to intense pressures that affect their well-being in the performance of their tasks. In this paper, the job demands–resources theoretical framework is adopted
to analyze the relationships between job demands, job resources, and the subjective well-being of a large sample of 739 accounting experts at the European level. Applying a structural equations model, the results confirm, on the one hand, the direct effects provided in the theoretical framework and, on the other, a new mediating role of job demands–subjective well-being relationship resources

Efecto del tamaño de la ventana de promediado y la histéresis variable en algoritmos de handover horizontal en redes convergentes
En las redes convergentes inalámbricas, el traspaso horizontal entre distintos puntos de acceso de la red WLAN es una gran fuente de degradación de la calidad de la VoIP y otros servicios conversacionales en tiempo real. Esto es debido a que este tipo de redes no fueron concebidas originalmente para soportar este tipo de servicios, y los traspasos siguen un protocolo ¿cortar antes de realizar¿, produciéndose interrupciones en la comunicación motivadas por el tiempo que necesitan los terminales en volver a asociarse a la red. En este artículo se estudia el efecto que tienen el tamaño de la ventana de promediado de la señal, la histéresis variable y el retardo del handover por parecido entre potencia de puntos de acceso de destino sobre el número de traspasos y las caídas de la potencia de señal por debajo del valor de sensibilidad del terminal, causantes principales de las interrupciones en la comunicación, y, con ello, de la degradación de la calidad de las comunicaciones
Despliegues de femtoceldas LTE en interiores comparación con otras tecnologías inalámbricas
Long Term Evolution (LTE) has appeared with the aim of improving the performance of 3G networks, increasing spectral efficiency and peak rates both at downlink and uplink, reducing latency and increasing flexibility of frequency allocation. Therefore, LTE is expected to have a key role in the development of wireless networks and services in the next years, and, of course, in specific dedicated in-building solutions. Due to that fact, an analysis of LTE performance in indoor scenarios in terms of capacity and grade of service is essential, as well as its comparison with other indoor solutions, pointing out the technical challenges derived, and describing and proposing performance assessment rules to be used in LTE deployments
