Caracterización arqueométrica de las producciones del Alfar de el Rinconcillo (Cádiz, España)
La excavación de un sector del alfar romano de El Rinconcillo (Algeciras,
Cádiz) en 1991 permitió estudiar parte del complejo alfarero en el que se pro
ducían mayoritariamente ánforas y en menor cantidad, cerámica de cocina y mesa,
extendiéndose su utilización desde el segundo tercio del s. 1 a.C. hasta el segundo
cuarto del s. 1 d.C.
En este trabajo se realiza la caracterización arqueométrica de las produccio
nes con el fin de establecer grupos de referencia para futuros hallazgos de cerá
micas en otras excavaciones que nos permitan profundizar en el estudio de las
relaciones comerciales entre distintas áreas en la Antigüedad. Al mismo tiempo,
se determina la evolución de las condiciones de producción a lo largo de las dis
tintas fases de uso del alfar, tanto respecto a las materias primas empleadas como
a las condiciones de cocción en los homos, analizándose las relaciones entre la
tipología y la funcionalidad de las ánforas y sus parámetros arqueométricos

Intention to purchase sustainable craft products: a moderated mediation analysis of the adoption of sustainability in the craft sector
In the modern world, the management of companies has evolved from a model characterized by the extraction, transformation, and generation of waste towards a more sustainable model. This transition affects even more traditional sectors, such as crafts. A key aspect of the transition towards more sustainable models is knowledge of the disposition of consumers with respect to these new artisan products. To date, few works have addressed this research problem, so this paper analyses consumer behaviour towards sustainable craft products empirically. To accomplish this goal, the effect of the image of sustainable craft products as perceived by consumers on their purchase intention is studied. Attitudes towards sustainable crafts, purchase intention, degree of consumer involvement and degree of knowledge concerning sustainability are considered as moderating variables. A questionnaire was distributed to a sample of handicraft consumers, and confirmatory factor analysis and an ordinary least squares regression model were used to study the data thus obtained. The results showed that the image of sustainable craft products as perceived by consumers influences their purchase intentions. In addition, this influence is increased when consumer attitudes towards and involvement with sustainable craft products increase. The results of this study can be useful for the sustainable crafts sector with respect to incorporating more sustainable products and designing marketing and communication strategies to help consumers learn about sustainability
Contrast sensitivity evaluation with filter contact lenses in patients with retinitis pigmentosa: a pilot study
Purpose: the aim of this pilot study was to test whether retinitis pigmentosa patients would benefit from filter contact lenses as an effective optical aid against glare and photophobia.
Methods: fifteen subjects with retinitis pigmentosa were enrolled in this study. All of them were evaluated with filter soft contact lenses (MaxSight), filter glasses (CPF 527) and without filters (control). All patients were assessed for the three aid conditions by means of best corrected visual acuity (BCVA), contrast sensitivity (without glare and with central and peripheral glare)(CSV-1000) and a specific subjective questionnaire about quality of vision.
Results: BCVA was slightly better with filters than without filter but the differences were not statistically significant. Contrast sensitivity without glare improved significantly with the contact lenses (p<0.05). The central glare had significant differences for the frequencies of 3 cpd and 18 cpd between the contact lens filter and the control group (p=0.021 and p=0.044, respectively). For the peripheral glare contrast sensitivity improved with contact lens versus control group for highest frequencies, 12 and 18 cpd (p<0.001 and p=0.045, respectively). According to the questionnaire the contact lens filter gave them more visual comfort than the glasses filter under the scenarios of indoors glare, outdoors activities and indoors comfort.
Conclusion: the filter contact lenses seem to be a good option to improve the quality of vision of patients with retinitis pigmentosa

Risk factors and biochemical markers in metabolic bone disease of premature newborns
Background: Metabolic bone disease (MBD) of prematurity is a complication of multifactorial aetiology, which has been increasing, due to progressive decrease in mortality of preterm newborns. The aim of the study was to analyze risk factors of severe MBD and its analytical markers. Patients and Method: Retrospective study involving preterm infants less than 32 weeks gestational age and/or weight less tan 1, 500 g born between january 2012 and december 2014. Comparison was made according to the presence of severe MBD. Results: 139 patients were recruited. Mean value of 25(OH)D3 was 70.68 ± 25.20 nmol/L, being higher in patients born in spring-summer than in autumn-winter (80.94 ± 25.33 vs 61.13 ± 21.07; p = 0.000). Levels of 25(OH)D3 were similar in patients with severe MBD compared with the rest of patients (65.61 ± 26.49 vs 72.07 ± 24.89, P = 0.283). Higher levels of alkaline phosphatase (AP, IU/L) (1314.19 ± 506.67 vs 476.56 ± 188.85; p = 0.000) were found in these patients. Cutoff point of AP 796.5 IU/L (S 95.2%, specificity 92.4%) was calculated by ROC curve. The risk factors most associated to severe EMO were restricted fetal growth, birth weight, duration of ventilation therapy and parenteral nutrition. Conclusions: AP levels were the best marker of severe MBD development. EMO risk increases with the number of risk factors and lower levels of 25(OH) D3. Levels of 25(OH)D3 higher than 70nmol/L appear to protect from the development of severe MBD, even in patients with multiple risk factors.
Introducción: La enfermedad metabólica ósea (EMO) del recién nacido prematuro (RNPT) es una complicación de origen multifactorial, que ha ido en aumento, consecuencia de la disminución progresiva de la mortalidad. El objetivo del estudio fue analizar los factores de riesgo (FR) pre y postnatales relacionados con la EMO severa y sus marcadores analíticos. Pacientes y Métodos: Estudio retrospectivo observacional, descriptivo y analítico, que incluyó RNPT nacidos con menos de 32 semanas y/o peso menor de 1.500 g entre enero de 2012 y diciembre de 2014. Se analizó la muestra en función del desarrollo de EMO severa. Resultados: 139 pacientes, con 25(OH)D3 media de 70,68 ± 25,20 nmol/l, mayor en los nacidos en primavera-verano que en otoño-invierno (80,94 ± 25,33 vs 61,13±21,07; p = 0,000). Los pacientes con EMO severa presentaron valores de 25(OH)D3 similares al resto de pacientes (65,61 ± 26,49 vs 72,07 ± 24,89; p = 0,283), y superiores de fosfatasa alcalina (FA) (1314,19 ± 506,67 vs 476,56 ± 188,85; p = 0,000). Mediante curva ROC se calculó un punto de corte de FA de 796,5 IU/l (S 95,2%, E 92,4%). Los FR más asociados al desarrollo de EMO severa fueron el crecimiento intrauterino restringido, el peso al nacimiento y la duración de ventiloterapia y nutrición parenteral. Conclusiones: Las cifras de FA son las que mejor se relacionan con el desarrollo de EMO severa. El riesgo de ésta aumenta a mayor número de factores de riesgo y menores cifras de vitamina D3. Niveles de 25(OH)D3 por encima de 70 nmol/l parecen proteger del desarrollo de EMO, incluso en pacientes con múltiples factores de riesgo
Adherence to the mediterranean diet is inversely associated with the prevalence of metabolic syndrome in older people from the north of Spain
Background: The aim of this study was to relate adherence to the Mediterranean diet (MedDiet) to the prevalence of metabolic syndrome (MetS) in an elderly population from the north of Spain. Methods: We carried out an observational, descriptive, cross-sectional, and correlational study involving 556 non-institutionalised individuals aged 65 to 79 years. The MEDAS-14 questionnaire score was used to define the degree of adherence to the Mediterranean diet. The diagnosis of MetS was conducted using the International Diabetes Federation (IDF) criteria. Results: In 264 subjects with an average age of 71.9 (SD: ±4.2), 39% of whom were men, 36.4% had good adherence (score ? 9 in MEDAS-14), with no differences by gender or age. The prevalence of MetS was 40.2%, with 47.6% in men and 35.4% in women (p < 0.05). The prevalence of MetS was 2.4 times more frequent among individuals who consumed less than two servings (200 g) of vegetables daily compared with those who consumed two or more servings of vegetables daily (OR: 2.368, 95%CI: 1.141?4.916, p = 0.021). Low adherence to the MedDiet (MEDAS-14 score ? 8) was associated with an 82% higher prevalence of MetS (OR: 1.817, 95%CI: 1.072?3.081, p = 0.027). Conclusion: An inverse relationship was established between adherence to the MedDiet and the prevalence of MetS.Funding: This research received no external funding.

This work was carried out within the frame of FEDER-Infrastructure: IE19_198 UGR and OBEMIRISK EFSA-Partnering Grant Project GP/EFSA/ENCO/2018/03-GA04.Integrated data from molecular and improved culturomics studies might offer holistic insights
on gut microbiome dysbiosis triggered by xenobiotics, such as obesity and metabolic disorders.
Bisphenol A (BPA), a dietary xenobiotic obesogen, was chosen for a directed culturing approach
using microbiota specimens from 46 children with obesity and normal-weight profiles. In parallel,
a complementary molecular analysis was carried out to estimate the BPA metabolising capacities.
Firstly, catalogues of 237 BPA directed-cultured microorganisms were isolated using five selected
media and several BPA treatments and conditions. Taxa from Firmicutes, Proteobacteria, and Actinobacteria
were the most abundant in normal-weight and overweight/obese children, with species
belonging to the genera Enterococcus, Escherichia, Staphylococcus, Bacillus, and Clostridium. Secondly,
the representative isolated taxa from normal-weight vs. overweight/obese were grouped as BPA
biodegrader, tolerant, or resistant bacteria, according to the presence of genes encoding BPA enzymes
in their whole genome sequences. Remarkably, the presence of sporobiota and concretely Bacillus
spp. showed the higher BPA biodegradation potential in overweight/obese group compared to
normal-weight, which could drive a relevant role in obesity and metabolic dysbiosis triggered by
these xenobiotics.OBEMIRISK EFSA-Partnering Grant GP/EFSA/ENCO/2018/03-GA04FEDER-Infrastructure IE19_198 UG

Pleistocene and Holocene hunter – gatherers in Iberia and the Gibraltar Strait: the current archaeological record, aims to be an updating of the current knowledge on human predatory societies settled in Iberia. The archaeological record of that region is essential for the reconstruction of Human Evolution in Europe in biological, behavioural and cultural domains thus it preserves the earliest and more significant records of the humanization in the continent and because it allows the recovery of the main trends in that process. This is possible thanks to a rich, large and complete record, encompassing all the stages on that development and all the adaptive and cultural modes. Moreover, the discovery of that record is amongst the earliest known archaeological occurrences in the history of our discipline, materialized already during the XIX century.
The main aim of that volume is the systematic presentation of the current empirical data written by the same research teams already on work every year on the excavation and analysis of the sites. We have included the current knowledge on the main archaeo-palaeontological sites, those bearing the more significant record. These sites are arranged in eight physiographic and geological regions with the aim of making clear the adaptive ways of human societies to similar environments. Beyond these eight regions it seemed important to us to present the heritage of symbolic behaviour on the caves of the two regions bearing the more extensive record of that cultural trait: the Cantabrian and the Levantine regions. The cave paintings coming from outside these two regions are presented in their own region.
Finally, beyond the empirical data, we would like to highlight the main research lines in which the modern Iberian Archaeology is currently engaged in the field of Human Evolution and Palaeoecology.Peer reviewe
