RESUMEN
The Mediterranean diet (MD) is one of the healthiest ones and is associated with a lower incidence of cardiovascular and cerebrovascular diseases as well as cancer. Extra virgin olive oil (EVOO) is probably the most idiosyncratic component of this diet. EVOO has been attributed with many healthful effects, which may be due to its phenolic components, e.g. including hydroxytyrosol (HT). Recent studies suggest that EVOO and HT have molecular targets in human tissues and modulate epigenetic mechanisms. DNA methylation is one of the most studied epigenetic mechanisms and consists of the addition of a methyl group to the cytosines of the DNA chain. Given the purported health effects of EVOO (poly)phenols, we analyzed the changes induced by HT in DNA methylation, in a colorectal cancer cell line. Caco-2 cells were treated with HT for one week or with the demethylating agent 5'-azacytidine for 48 h. Global DNA methylation was assessed by ELISA. DNA bisulfitation was performed and Infinium Methylation EPIC BeadChips were used to analyze the specific methylation of CpG sites. We show an increase in global DNA methylation in Caco-2 cells after HT treatment, with a total of 32,141 differentially methylated (CpGs DMCpGs). Interestingly, our analyses revealed the endothelin receptor type A gene (EDNRA) as a possible molecular target of HT. In summary, we demonstrate that cellular supplementation with HT results in a specific methylome map and propose a potential gene target for HT.

Cell-to-cell communication strategies include extracellular vesicles (EVs) in plants and animals. The bioactive molecules in a diet rich in vegetables and fruits are associated with disease-preventive effects. Plant-derived EVs (PDEVs) are biogenetically and morphologically comparable to mammalian EVs and transport bioactive molecules, including miRNAs. However, the biological functions of PDEVs are not fully understood, and standard isolation protocols are lacking. Here, PDEVs were isolated from four foods with a combination of ultracentrifugation and size exclusion chromatography, and evaluated as vehicles for enhanced transport of synthetic miRNAs. In addition, the role of food-derived EVs as carriers of dietary (poly)phenols and other secondary metabolites was investigated. EVs from broccoli, pomegranate, apple, and orange were efficiently isolated and characterized. In all four sources, 4 miRNA families were present in tissues and EVs. miRNAs present in broccoli and fruit-derived EVs showed a reduced RNase degradation and were ferried inside exposed cells. EVs transfected with a combination of ath-miR159a, ath-miR162a-3p, ath-miR166b-3p, and ath-miR396b-5p showed toxic effects on human cells, as did natural broccoli EVs alone. PDEVs transport trace amounts of phytochemicals, including flavonoids, anthocyanidins, phenolic acids, or glucosinolates. Thus, PDEVs can act as nanocarriers for functional miRNAs that could be used in RNA-based therapy.

BACKGROUND: The COVID-19 pandemic has changed the organisational and management strategies of healthcare institutions such as primary care centres. Organisational culture as well as leadership style are key issues for the success of these institutions. Due to the multidimensional nature of identity processes, it is necessary to explore the changes experienced by health professionals from these perspectives. This study explores health professionals' organisational and management strategies in primary care settings during the COVID-19 pandemic. DESIGN: Qualitative, exploratory study based on the analysis of participants' accounts within a hermeneutic phenomenologicaly approach. METHODS: Research was conducted in primary care settings in two neighbouring Spanish healthcare regions. The sample included participants with different demographics (gender, age), professional roles (practice managers, general practitioners, paediatricians), employment status (permanent, temporary, zero-hours), and years of experience (under or over ten years' experience). Data were collected between July and December 2020 through focus groups and in-depth, semi-structured individual interviews. RESULTS: A total of 53 primary care workers participated in the study, of which 38 were individually interviewed and 15 participated in three focus groups. Of these, 78.4% were healthcare professionals, 49% were female nurses, and 70.5% had more than 10 years of work experience in primary care. Two main themes emerged: "liquid" healthcare and "the best healthcare system in the world". During the first wave of the COVID-19 pandemic, new, more fluid organisational and management models were implemented in primary care settings, which have remained in place since. Primary care workers' perceived a lack of appreciation and inclusion in decision-making that risked their alienation and disengagement. CONCLUSION: Primary care workers' professional identity became gradually blurred due to shifting perceptions of their professional roles in a context of increasing improvisation and flexible working practices. This affected their professional performance. TRIAL REGISTRATION: The study was approved by the Clinical Research Ethical Committee of the Talavera de la Reina Integrated Management Area (CEIm del AGI de Talavera de la Reina in Spain, Hospital Nuestra Señora del Prado, ref: 23/2020).

The olive ridley sea turtle, Lepidochelys olivacea (Eschscholtz, 1829), nests en masse in the protected natural area of La Escobilla, Mexico. On this beach, Omorgus suberosus (Fabricius, 1775), a sapro-necrophagous beetle, feeds on the sea turtles' decomposing and live eggs and is considered to be a threat for the conservation of L. olivacea. However, the abundance and reproductive phenology of O. suberosus in relation to the spatial and temporal availability of this food resource are unknown. We tested two alternative hypotheses during the 2013-2014 nesting season of L. olivacea: (i) abundance and female reproductive phenology of beetles are determined by the spatial and temporal availability of decomposing eggs that accumulate during the turtle nesting season, and (ii) abundance and female reproductive phenology of beetles are related to the increase in the concentration of seasonal and/or new turtle nests. Twenty-four plots (1 m2) were sampled in three areas with different turtle nesting densities. Spatially, beetle abundance was greater where turtle nest density was high and decomposed eggs were abundant. At the temporal level, old nests (> 45 days after egg deposition) were abundant and the presence of seasonal and new nests (~ 45 or fewer days after egg deposition) appeared to trigger sexual maturation in female beetles. Immature female beetles were more abundant throughout the turtles' nesting season, and mature females were only abundant during the turtle arribadas with the highest number of seasonal nests. We conclude that abundance and female reproductive phenology of O. suberosus females are influenced by the quantity and quality of the resource. These findings are useful to understand the interaction of L. olivacea with other species and to strengthen the conservation plans of this turtle species.

In Austria, single-stage vertical flow (VF) wetlands with intermittent loading are a state-of-the-art technology for treating domestic wastewater. They are designed according to the Austrian design standard with a specific surface area of 4 m2 per person (i.e. 20 g COD/(m2·d)) and thus demand a bigger amount of land to treat the same amount of wastewater compared to intensified technical treatment systems. In order to reduce the amount of land needed, a modified design for VF wetlands has been proposed. The modified design has a specific surface area of 2.5 m2 per person (i.e. 32 g COD/(m2·d)) and it has been shown to be able to meet the Austrian effluent requirements. To allow higher organic loading, more loadings per day but lower volume of a single loading, a constant loading interval, and increased number of openings per m2 are applied. A simulation study using the HYDRUS Wetland Module was carried out to compare the treatment efficiencies of single-stage VF wetlands with classical and modified design. Data from a classical Austrian single-stage VF wetland was used for calibration of the model using the standard parameter set for the CW2D biokinetic model. The influent COD fractionation was calibrated to adapt to the wastewater. The simulations showed a good performance of the modified design compared to a classical VF wetland for COD removal with COD effluent concentrations in winter (effluent water temperature of 4.5 °C) of 35 and 29 mg/L, respectively. The simulation study showed that during high-loading events the VF wetland with modified design has lower maximum NH4-N effluent concentrations. Single-stage VF wetlands with modified design seem to be very effective and allow application of higher organic loads compared to single-stage VF wetlands with classical design.

Given increasing popularity of triathlon, the objective of this study was to evaluate the acute effects upon the health of triathletes. To do so, with a sample of 23 male athletes (34.4 ± 7.9 years old), an assessment was carried out both before and after an Olympic distance triathlon, of the bodily composition, the jumping ability and the BORG and VAS scales, as well as a blood analysis of the following: Lactate (mmol/L), Hematrocrit (%), Glucose (mg/dL), Total proteins (mg/dL), Triglycerides (mg/dL), Bilirubin (mg/dL), GOT (IU/L), GPT (IU/L), LDH (IU/L), CPK (IU/L). The results showed an increase (p < 0.001) in the different markers of metabolic stress and muscular damage following the triathlon, but always within a normal range considered to be healthy, with the exception of CPK (IU/L) (PRE 149.33 ± 108.16 vs POST 290.10 ± 102.48). Therefore, it would seem that competing in an Olympic-distance triathlon does not pose health risks for trained subjects.

[Purpose] The aim of this study was to investigate whether or not a single whole-body vibration treatment after eccentric exercise can reduce muscle soreness and enhance muscle recovery. [Subjects and Methods] Twenty untrained participants were randomly assigned to two groups: a vibration group (n=10) and control group (n=10). Participants performed eccentric quadriceps training of 4 sets of 5 repetitions at 120% 1RM, with 4â min rest between sets. After that, the vibration group received 3 sets of 1â min whole body vibration (12â Hz, 4â mm) with 30â s of passive recovery between sets. Serum creatine kinase, blood urea nitrogen, muscle soreness (visual analog scale) and muscle strength (peak isometric torque) were assessed. [Results] Creatine kinase was lower in the vibration group than in the control group at 24â h (200.2 ± 8.2 vs. 300.5 ± 26.1 U/L) and at 48â h (175.2 ± 12.5 vs. 285.2 ± 19.7 U/L) post-exercise. Muscle soreness decreased in vibration group compared to control group at 48â h post-exercise (34.1 ± 11.4 vs. 65.2 ± 13.2â mm). [Conclusion] Single whole-body vibration treatment after eccentric exercise reduced delayed onset muscle soreness but it did not affect muscle strength recovery.
RESUMEN
INTRODUCTION: EndoPredict (EP) is an RNA-based multigene test that predicts the likelihood of distant recurrence in patients with estrogen receptor-positive (ER+), human epidermal growth factor receptor 2-negative (HER2-) breast cancer (BC) who are being treated with adjuvant endocrine therapy. Herein we report the prospective-retrospective clinical validation of EP in the node-positive, chemotherapy-treated, ER+/HER2- BC patients in the GEICAM 9906 trial. METHODS: The patients (N = 1,246) were treated either with six cycles of fluorouracil, epirubicin and cyclophosphamide (FEC) or with four cycles of FEC followed by eight weekly courses of paclitaxel (FEC-P), as well as with endocrine therapy if they had hormone receptor-positive disease. The patients were assigned to EP risk categories (low or high) according to prespecified cutoff levels. The primary endpoint in the clinical validation of EP was distant metastasis-free survival (MFS). Metastasis rates were estimated using the Kaplan-Meier method, and multivariate analysis was performed using Cox regression. RESULTS: The molecular EP score and the combined molecular and clinical EPclin score were successfully determined in 555 ER+/HER2- tumors from the 800 available samples in the GEICAM 9906 trial. On the basis of the EP, 25% of patients (n = 141) were classified as low risk. MFS was 93% in the low-risk group and 70% in the high-risk group (absolute risk reduction = 23%, hazard ratio (HR) = 4.8, 95% confidence interval (CI) = 2.5 to 9.5; P < 0.0001). Multivariate analysis showed that, in this ER+/HER2- cohort, EP results are an independent prognostic parameter after adjustment for age, grade, lymph node status, tumor size, treatment arm, ER and progesterone receptor (PR) status and proliferation index (Ki67). Using the predefined EPclin score, 13% of patients (n = 74) were assigned to the low-risk group, who had excellent outcomes and no distant recurrence events (absolute risk reduction vs high-risk group = 28%; P < 0.0001). Furthermore, EP was prognostic in premenopausal patients (HR = 6.7, 95% CI = 2.4 to 18.3; P = 0.0002) and postmenopausal patients (HR = 3.3, 95% CI = 1.3 to 8.5; P = 0.0109). There were no statistically significant differences in MFS between treatment arms (FEC vs FEC-P) in either the high- or low-risk groups. The interaction test results between the chemotherapy arm and the EP score were not significant. CONCLUSIONS: EP is an independent prognostic parameter in node-positive, ER+/HER2- BC patients treated with adjuvant chemotherapy followed by hormone therapy. EP did not predict a greater efficacy of FEC-P compared to FEC alone.

Sedimentary records help chronologically identify anthropogenic contamination in environmental systems. This study analysed dated sediment cores from L'Albufera Lake (Valencia, Spain), to assess the occurrence of heavy metals (HMs), polycyclic aromatic hydrocarbons (PAHs), perfluoroalkyl substances (PFASs), organophosphorus flame retardants (OPFRs), pesticides and pharmaceuticals and personal care products (PPCPs). The results evidence the continuing vertical presence of all types of contaminants in this location. The sediment age was difficult to establish. However, the presence of shells together with an historical estimation and the knowledge of sedimentary rates could help. HMs contents are higher in the upper layer reflecting the most recent increase of the industrial and agricultural practices in the area since the middle 20th century. Higher availability index of these HMs in the upper sediment layers is associated with point and diffuse contamination sources in the area. PAHs and OPFRs were homogeneous distributed through the sediments with few exceptions such as phenanthrene in the North and fluoranthene in the South. Perfluorooctanoic acid (PFOA) and perfluorooctanesulfonate (PFOS) were detected throughout the sediment core while short-chain PFASs (except perfluoropentanoic acid (PFPeA)) were detected only in the top layer. Pesticides and PPCPs showed appreciable down-core mobility. The vertical concentration profiles of organic contaminants did not exhibit a clear trend with depth, then, it is difficult to develop a direct relationship between sediment age and contaminant concentrations, and to elucidate the historical trend of contamination based on dated sediment core. Consequently, linking contaminant occurrence in sediments directly to their historical use is somewhat speculative at least in the conditions of L'Albufera Lake.
RESUMEN
The increasing prevalence of microplastics (MP) in urban environments has raised concerns over their negative effects on ecosystems and human health. Stormwater runoff, and road dust and sediment, act as major vectors of these pollutants into natural water bodies. Sustainable urban drainage systems, such as permeable pavements, are considered as potential tools to retain particulate pollutants. This research evaluates at laboratory scale the efficiency of permeable interlocking concrete pavements (PICP) and porous concrete pavements (PCP) for controlling microplastics, including tire wear particles (TWP) which constitute a large fraction of microplastics in urban environments, simulating surface pollution accumulation and Mediterranean rainfall conditions. Microplastic levels in road dust and sediments and stormwater runoff inputs were 4762 ± 974 MP/kg (dry weight) and 23.90 ± 17.40 MP/L. In infiltrated effluents, microplastic levels ranged from 2.20 ± 0.61 to 5.17 ± 1.05 MP/L; while tire wear particle levels ranged between 0.28 ± 0.28 and 3.30 ± 0.89 TWP/L. Distribution of microplastics within the layers of PICP and PCP were also studied and quantified. Microplastics tend to accumulate on the pavements surface and in geotextile layers, allowing microplastic retention efficiencies from 89 % to 99.6 %. Small sized (< 0.1 mm) fragment shaped microplastics are the most common in effluent samples. The results indicate that permeable pavements are a powerful tool to capture microplastics and tire wear particles, especially by surface and geotextile layers. The study aims to shed light on the complex mobilisation mechanisms of microplastics, providing valuable insights for addressing the growing environmental concern of microplastic pollution in urban areas.
RESUMEN
The chronological information provided by sediment cores about the beginning and evolution of anthropogenic contaminants is crucial for understanding the influence of humans on the environment. The dataset provides information about the vertical distribution of heavy metals (HMs), metalloids and various organic contaminants (OCs) including contemporary contaminants of emerging concern (CECs), such as pharmaceuticals and personal care products (PPCPs) and pesticides; as well as persistent organic contaminants (POPs) such as polycyclic aromatic hydrocarbons (PAHs), perfluoroalkyl substances (PFASs), organophosphorus flame retardants (OPFRs) in sediment cores of two different sampling areas (North and South) of L'Albufera lake. Additional information about the 14C-data of the organic matter present in the different layers of the sediment cores, and the 14C-data of the seashells found in some of them are shown. The dataset includes physico-chemical analyses of sediment characteristics at the different selected depth levels such as Organic Carbon (Corg), Inorganic Carbon (IC), Total Nitrogen (TN), Total Sulphur (TS) and texture. Furthermore, ecological risk assessment of these contaminants in surface sediment layers is performed to ascertain is potential toxicity. These data supplement the findings presented and considered in the research article "Exploring Organic and Inorganic Contaminant Histories in Sediment Cores Across the Anthropocene: Accounting for Site/Area Dependent Factors". Therefore, these data altogether are useful for researchers seeking to assess long-term impact of contamination.
RESUMEN
To identify a group of patients who might benefit from the addition of weekly paclitaxel to conventional anthracycline-containing chemotherapy as adjuvant therapy of node-positive operable breast cancer. The predictive value of PAM50 subtypes and the 11-gene proliferation score contained within the PAM50 assay were evaluated in 820 patients from the GEICAM/9906 randomized phase III trial comparing adjuvant FEC to FEC followed by weekly paclitaxel (FEC-P). Multivariable Cox regression analyses of the secondary endpoint of overall survival (OS) were performed to determine the significance of the interaction between treatment and the (1) PAM50 subtypes, (2) PAM50 proliferation score, and (3) clinical and pathological variables. Similar OS analyses were performed in 222 patients treated with weekly paclitaxel versus paclitaxel every 3 weeks in the CALGB/9342 and 9840 metastatic clinical trials. In GEICAM/9906, with a median follow up of 8.7 years, OS of the FEC-P arm was significantly superior compared to the FEC arm (unadjusted HR = 0.693, p = 0.013). A benefit from paclitaxel was only observed in the group of patients with a low PAM50 proliferation score (unadjusted HR = 0.23, p < 0.001; and interaction test, p = 0.006). No significant interactions between treatment and the PAM50 subtypes or the various clinical-pathological variables, including Ki-67 and histologic grade, were identified. Finally, similar OS results were obtained in the CALGB data set, although the interaction test did not reach statistical significance (p = 0.109). The PAM50 proliferation score identifies a subset of patients with a low proliferation status that may derive a larger benefit from weekly paclitaxel.

Lake Albufera is one of the most eutrophic bodies of water in Spain due to point and diffuse pollution over past decades, and its sediments are likely to be anoxic because of high organic matter flux. Hence, sulphides can play an important role in limiting the mobility of heavy metals. This study aimed to study the vertical variation of acid volatile sulphide (AVS) and simultaneously extracted metals (SEM) in sediment cores collected from Lake Albufera; other sediment characteristics, such as organic matter, biochemical oxygen, demand or total metals, were also studied. Three sites were selected, and four sampling campaigns were performed to study spatial and temporal variation as well as to obtain information regarding historical variation in the composition of sediments. AVS and SEM were analysed by the purge-and-trap method. The vertical distribution of AVS and SEM varied depending on the sampling site-concentrations of AVS and SEM were higher at sites close to mouths of inflowing channels. A decreasing trend of AVS has been found at these sites over time: In the two first samplings, AVS increased with depth reaching maximum concentrations of 40 and 21 µmol g(-1), but from then on AVS were lower and decreased with depth. SEM decreased with depth from 3 µmol g(-1) in surface layers to approximately 1 µmol g(-1) at deeper segments at these sites. However, the central site was more uniform with respect to depth as well as with time; it presented lower values of SEM and AVS (mean 0.9 and 2.0 µmol g(-1) respectively), and the maximum value of AVS (7 µmol g(-1)) was found at the top layer (0-3 cm). According to the (SEM-AVS)/fOC approach, every site, and throughout the cores, can be classified as containing nontoxic metals because the values were <130 µmol g(-1).

Treatment wetlands (TWs) are an efficient technology for removing microplastics (MPs) from wastewater, according to previous studies. This study investigates the dynamics and fate of MPs in two wastewater treatment plants (WWTPs) using TWs, one with horizontal subsurface flow (HF) and another with a floating plant system (FS). Special attention is paid to the retention produced in the sludge and the role of macrophyte roots. The abundance of MPs in the influent to the WWTPs was on average 20.3 ± 0.85 MP/L and 8.4 ± 1.13 MP/L in HF and FS respectively, while the effluent had 0.58 ± 0.07 MP/L and 0.17 ± 0.06 MP/L, thus giving overall efficiencies of 97.42% and 98.13%, respectively. In the HF wetland, sludge samples near the inlet and the outlet were taken, distinguishing between sludge adhered to gravel and sludge attached to roots. In the floating macrophytes, sludge samples from secondary and tertiary treatments were taken. The results indicate that roots play a significant role in MPs retention. In the HF wetland, the complex formed by roots and gravel attached more MPs than gravel alone in the final zone of the wetland. In the FS, roots retained a significant quantity of MPs, both in the secondary and tertiary treatments, thus giving rise to a sludge less concentrated in MPs. This study aims to improve the knowledge of MPs behavior and fate in full-scale TWs, providing valuable information to enhance retention efficiency.

This qualitative ethnographic study identifies how problems in the feeding process of a group of people with functional diversity influence different eating situations. The study, which was carried out in the Autonomous Community of Castilla La Mancha, Spain, is based on interviews conducted at the headquarters of the different participating associations for functionally diverse people, at the participants' homes, and in public spaces. The study included 27 subjects aged between 18-75 years. Their functional diversity had caused significant changes in their sociability, particularly in contexts associated with food consumption. The analysis identified three main themes: social ghettoisation and culinary loneliness; stigma, shame, feeling like a burden, and loneliness; and exclusion or self-exclusion at the dining table. Our participants' narratives underscored the importance of acknowledging the significance of changes in eating-related sociability due to functional diversity. For the study subjects, grief, loneliness, and shame contributed to disassociating food consumption from social celebrations, withdrawing from restaurant meals, or conversations while eating to avoid other people's stares.

A full-scale treatment wetland (TW) (100 inhabitants, 14 m3·d-1), composed of two horizontal subsurface flow wetlands (TW1-400 m2 and TW2-200 m2) and a small pond (13 m2), has been evaluated for Escherichia coli (E. coli) removal. The results indicate a global removal from 1.74·106 to 685 MPN·100 mL-1 (3.41 log units), reducing E. coli sufficiently to reach values suitable for reuse purposes such as agricultural reuse, without energy and reagent consumption. The small pond at the end of the treatment train plays an important role in E. coli removal and biodiversity enhancement. Data from TW1 and TW2 have been fitted to the P-k-C* model, giving values of 134 and 100 m·yr-1 for the first-order kinetic reaction coefficient. For the pond, a process-based model using continuous stirred-tank reactor (CSTR) and a 3d-CFD model have been implemented and compared. The models indicate that solar disinfection and predation by daphnids are the most important mechanisms in the studied pond, representing 65% and 25% of the removal respectively. It can be concluded that CSTR can provide good results for small ponds and 3d-CFD model provides extra information, useful to enhance their design.

BACKGROUND: Pandemics and epidemics have represented public health emergencies with severe consequences at a global level. Primary care teams have played a crucial role in disease surveillance and monitoring during the COVID-19 pandemic through early detection, contact tracing, and isolation of positive cases. The objective of this study was to explore the impact of the COVID-19 pandemic on primary care teams regarding their internal dynamics and their professional performance. METHODS: Qualitative study carried out between July and December 2020 in two large central and southern Spanish regions (Castilla la Mancha and Madrid). Semi-structured interviews and focus groups were conducted with primary care workers. Data was analysed using thematic content analysis. Participants were accessed using purposive sampling. RESULTS: A total of 53 primary care workers participated in the study, of which 38 were individually interviewed, and 15 participated in three focus groups.The analysis of their experiences revealed two main themes regarding the impact of the COVID-19 pandemic on primary care teams: 1) The need to reorganise traditional roles: Primary care settings closed their doors to the public and their workers restructured their roles to ensure the delivery of essential services; 2) The need to implement a new primary care delivery model: Each primary care team had to self-organise, making sure their reference population was cared for and developing resource optimisation strategies. CONCLUSIONS: Primary care teams have quickly adapted their roles and internal dynamics to respond to the demands generated by COVID-19. In the new delivery model, some positive aspects could be highlighted - such as increased communication between professionals and the use of telemedicine for some cases. However, it is important to address the negative impact that the COVID-19 crisis has had on of the main functions of primary care. These measures are necessary to promote well-being in primary care teams, and to provide quality care that addresses the complex and individual needs of each person and reduces inequalities in healthcare delivery.

OBJECTIVE: to explore the perception and experience of fathers of children with disabilities in caring for their children; to know their role and how these tasks impact their daily life, health and physical, mental and/or emotional well-being. METHODOLOGY: qualitative approach study with phenomenological design. The sample consisted of seven young fathers of underage children with various diagnoses. The data were collected through semi-structured interviews; the discourse analysis was carried out through open and axial coding processes. Three themes emerged from the results of the analysis: (1) shared responsibilities, (2) somewhat difficult to fit in, and (3) either you join or you split. RESULTS: Fathers must readjust their work schedule, reduce their working hours, or give up their job altogether to take care of their children, as well as give up their social life. They lack time to enjoy their leisure time, to spend time with their partner, to take care of themselves. This involvement in caregiving generates an important occupational imbalance that has repercussions above all on their mental health. CONCLUSIONS: The sharing of caregiving tasks also impacts significantly on parents' lives, it also takes away time and opportunities, and sometimes health and quality of life.
RESUMEN
This qualitative study explores the difficulties in experiencing eating-derived pleasure within a group of functionally diverse people, based on personal interviews and Grounded Theory. Understanding the feelings and subjective experiences of functionally diverse people can help develop new approaches to address their loss of pleasure and motivation regarding food intake. The study included 27 participants, aged between 18 and 75 years, all of whom had a functional deficiency that affected the occupational aspects of the eating process. Interviews were conducted in clinical settings and several centres for differently abled people. Four main themes emerged from the analysis: eating through obligation; fear of eating; the social life of food; and the importance of the taste and visual aesthetics of food. These themes underscore the importance of taking into account the phenomenological experiences of pleasure in the eating process.
RESUMEN
PURPOSE: This paper aims at describing the eating experience of people diagnosed with and treated for laryngeal cancer. Going beyond the mere conceptualization of "after-effect" or the quantification of the disease's impact on the basis of standardized questionnaires, we present a qualitative analysis of the narratives of such experiences. METHODS: Ethnographic study. Data is obtained from conversations, semi-structured interviews, participant observation, and written documents. A discourse analysis of the narrative information was conducted, with process coding and using the constant comparative method, inductive content analysis, category analysis, units of meaning associated with each other, and triangulation. RESULTS: The impact of cancer on eating processes is not limited to nutrition, but also affects the social and cultural value of food, which is put into question. The symbolic and social values which accompany the traditional way of eating are modified, which is connected with impaired quality of life. CONCLUSIONS: The impact on the eating process and its relationship with quality-of-life impairment are clear and connect with the importance of eating ways in culture and social organization. Greater attention should be paid to these contexts in clinical practice, which can affect even more than the impact on communicative processes.
