Physical activity shifts gut microbiota structure in aged subjects with overweight/obesity and metabolic syndrome.

We aimed to identify how physical activity (PA), within the context of a Mediterranean diet, affects metabolic variables and gut microbiota in older individuals with overweight/obesity and metabolic syndrome. Observational analysis was conducted as part of the PREDIMED-Plus study with 152 males and 145 females with overweight/obesity and metabolic syndrome. General assessments, anthropometric and biochemical measurements, and gut microbial 16S rRNA sequencing data were analyzed at baseline and 1-year of follow-up. Participants were stratified by tertiles of 1-year change in total PA-related energy expenditure ranging from -98.77 to 1099.99 METs (min/week). The total PA percentage of change was reduced in tertile 1 (-44.83 ± 24.94), increased in tertile 2 (28.96 ± 23.33) and tertile 3 (273.64 ± 221.42). Beta diversity analysis showed differences in the gut microbiota population within each tertile group. Significant differences were found at phylum, family, and genus levels in the gut microbiota of the three tertile groups at baseline and 1-year timepoint. Tertile 3, the group with the greatest increase in PA, was characterized by increases in their levels of Sutterella, Bilophila, and Lachnospira bacteria as well as a reduction in Collinsella. Moreover, this tertile showed a different pattern in its predicted metabolic capacities to the other groups. Our results have demonstrated that changes in PA such as lifestyle and Mediterranean diet induces specific variations in the gut microbiota profile. This modulation of gut microbiome populations and their metabolic capacities may contribute to the health of the aged individuals with overweight/obesity and metabolic syndrome.

A morphological and molecular approach to investigating infectious disease in early medieval Iberia: The necropolis of La Olmeda (Palencia, Spain).

OBJECTIVE: Here we investigate infectious diseases that potentially contribute to osteological lesions in individuals from the early medieval necropolis of La Olmeda (6th-11th c. CE) in North Iberia. MATERIALS AND METHODS: We studied a minimum number of 268 individuals (33 adult females; 38 adult males, 77 unknown/indeterminate sex; and 120 non-adults), including articulated and commingled remains. Individuals with differential diagnoses suggesting chronic systemic infectious diseases were sampled and bioinformatically screened for ancient pathogen DNA. RESULTS: Five non-adults (and no adults) presented skeletal evidence of chronic systemic infectious disease (1.87% of the population; 4.67% of non-adults). The preferred diagnoses for these individuals included tuberculosis, brucellosis, and malaria. Ancient DNA fragments assigned to the malaria-causing pathogen, Plasmodium spp., were identified in three of the five individuals. Observed pathology includes lesions generally consistent with malaria; however, additional lesions in two of the individuals may represent hitherto unknown variation in the skeletal manifestation of this disease or co-infection with tuberculosis or brucellosis. Additionally, spondylolysis was observed in one individual with skeletal lesions suggestive of infectious disease. CONCLUSIONS: This study sheds light on the pathological landscape in Iberia during a time of great social, demographic, and environmental change. Genetic evidence challenges the hypothesis that malaria was absent from early medieval Iberia and demonstrates the value of combining osteological and archaeogenetic methods. Additionally, all of the preferred infectious diagnoses for the individuals included in this study (malaria, tuberculosis, and brucellosis) could have contributed to the febrile cases described in historical sources from this time.

Intensity of Interprofessional Collaboration and related factors in Intensive Care Units. A descriptive cross-sectional study with an analytical approach.

OBJECTIVE: To determine the Intensity of Collaboration between the intensive care professionals of a third level hospital. METHOD: Descriptive cross-sectional study with an analytical approach. SETTING: 6 intensive care units of a third level hospital. SAMPLE: nurses and doctors. Consecutive type non-probabilistic sampling. DATA COLLECTION: sociodemographic, economic, motivation and professional satisfaction variables, and the intensity of collaboration using the "Scale of Intensity of Interprofessional Collaboration in Health." RESULTS: A total of 102 health professionals (91 nurses and 11 doctors) were included. The mean overall Intensity of Collaboration (IoC) was moderate. Men showed higher scores in all factors (p<.05). The IoC global score was higher in the group of professionals with ≤10 years of experience (p=.043) and those who were highly satisfied with the profession (p=.037). Physicians presented higher scores in the global IdC (p=.037) and in the Collaboration mean (p=.020) independently in the multivariate models. A negative linear relationship (rho: -0,202, p=.042) was observed between age and the overall IoC score. Professionals aged ≤30years reported a higher perception of Shared Activities (p=.031). Negative linear relationships were observed between years of experience and total IoC score (rho: -0,202, p=.042) and patients' Perception score (rho: -0.241, p=0.015). The research activity also showed to be a variable related to a greater degree of Collaboration at a global level and in some of the factors (p<.05). The scale of IoC obtained a Cronbach's α of 0,9. CONCLUSIONS: The intensity of interprofessional collaboration in ICUs is moderate. Professionals with experience of ≤10 years, a higher level of satisfaction and participation in research activities show a greater intensity of collaboration. Doctors perceive collaboration more intensely than nurses. All factors contribute equally to the internal consistency of the questionnaire.

Quality of life following transobturator sling surgery for female stress urinary incontinence.

OBJECTIVE: This descriptive study examines quality of life in women undergoing placement of a midurethral sling for stress urinary incontinence. MATERIALS AND METHODS: This was a retrospective cohort study based on data from 51 women consecutively undergoing this procedure at a tertiary hospital in the years 2014 and 2015. The main outcome variable was quality of life assessed through the Sandvick severity test and International Consultation on Incontinence Short Quality of Life Questionnaire (ICIQ-IU-SF) at the time points baseline or presurgery, and 6 months and 5 years postsurgery. Factors associated with treatment failure were determined through binary logistic regression. RESULTS: At 5-year follow up we obtained an absolute reduction of 8.78 points (95% CI 6.43-11.14; p < 0.001) in the ICIQ-IU-SF questionnaire and 4.54 (95% CI 3.25-5.83; p < 0.001) in the Sandvick severity test score, compared to baseline, in the 35 patients that completed follow-up. Out of the 51 patients that were followed, the rate of success in incontinence correction was 86.3% (44/50) with a failure rate of 12% (6/50). Multiparity and previous gynaecological surgery were identified as predisposing factors for treatment failure. Obesity was associated with a worse treatment outcome. CONCLUSION: Sling treatment for incontinence was successful in 86.3% (44/50) of participants and remained effective 5 years after surgery in terms of quality of life.

Uric acid and acute kidney injury in high-risk patients for developing acute kidney injury undergoing cardiac surgery: A prospective multicenter study.

PURPOSE: It is unclear whether preoperative serum uric acid (SUA) elevation may play a role in the development of acute kidney injury (AKI) associated with cardiac surgery (CSA-AKI). We conducted a cohort study to evaluate the influence of preoperative hyperuricemia on AKI in patients at high risk for developing SC-AKI. DESIGN: Multicenter prospective international cohort study. SETTING: Fourteen university hospitals in Spain and the United Kingdom. PARTICIPANTS: We studied 261 consecutive patients at high risk of developing CSA-AKI, according to a Cleveland score ≥ 4 points, from July to December 2017. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: AKIN criteria were used for the definition of AKI. Multivariable logistic regression models and propensity score-matched pairwise analysis were used to determine the adjusted association between preoperative hyperuricemia (≥7 mg/dL) and AKI. Elevated preoperative AUS (≥7 mg/dL) was present in 190 patients (72.8%), whereas CSA-AKI occurred in 145 patients (55.5%). In multivariable logistic regression models, hyperuricemia was not associated with a significantly increased risk of AKI (adjusted Odds Ratio [OR]: 1.58; 95% confidence interval [CI]: 0.81-3; P = .17). In propensity score-matched analysis of 140 patients, the hyperuricemia group experienced similar adjusted odds of AKI (OR 1.05, 95%CI 0.93-1.19, P = .37). CONCLUSIONS: Hyperuricemia was not associated with an increased risk of AKI in this cohort of patients undergoing cardiac surgery at high risk of developing CSA-AKI.

Raman spectra soft modeling of the biodiesel oxidation through evolving factor analysis & multivariate curve resolution.

The oxidative stability of biodiesel is defined by its relative resistance to the action of oxygen at room temperature. Its determination is an essential reference to the quality of biofuel and a significant parameter to be determined. This parameter concerns the quality of the biodiesel to be supplied to the consumer, and its determination is fundamental to maintaining the engine's proper functioning. Raman spectroscopy allows the rapid obtaining of structural information regarding biodiesel quality and, when aided by multivariate analysis methods, allows a quantitative determination of specific properties. This work uses Raman spectroscopy, Multivariate Curve Resolution with Alternative Least Squares (MCR-ALS) method, and Evolving Factor Analysis (EFA) to study biodiesel's oxidation kinetics. Also, the vibrational modes C = C, CH2, and CH3 were identified as the main structural groups involved in this process, corroborating previous studies. The MCR-ALS & EFA combination allowed modeling of the degradation kinetics following an A â†’ B â†’ C mechanism, where A corresponds to the biodiesel (starting material), B is related to the hydroperoxide mixture, and C is the final product. The results also suggested that this process follows a first-order reaction, with kinetic constant values of k1 = 0.0056 min-1 and k2 = 0.0031 min-1.

Childhood cancer survivors: current challenges.

Rates of childhood cancer survival in developed countries have risen to over 80-85 %. In consequence, the population of childhood cancer survivors (CCS) has grown considerably. Nevertheless, CCS present a high morbidity and mortality due to cancer or its treatment, with an increased risk of premature mortality, second primary tumors and late side effects, both physical and psychosocial, all of which decrease the quality of life. Long-term follow-up (LTFU) of CCS is recommended to prevent, detect and treat those health problems. Despite the advances achieved, the management of CCS is still not optimal. Among the areas for improvement discussed in this manuscript are: (1) Quantifying the real burden of morbimortality, by implementing new frequency measures (mean cumulative count and cumulative burden), to obtain more accurate assessments, and using simulation models, to determine individual risks; (2) Assessing the impact of risk factors for late side effects, related to the patient, tumor type, treatments, lifestyle, comorbidities, genetics and ageing; (3) Considering the impact of the international harmonisation of long-term follow-up guidelines, to generate homogeneous, evidence-based recommendations and an individualized LTFU and, (4) Challenges to LTFU implementation, considering models of care adapted to patient risk and needs, with special attention to the transition to adult-care follow-up. Finally, we comment on the situation of CCS in Spain and consider future prospects for improving the health and quality of life of this population.

Prematurity and congenital malformations differ according to the type of pregestational diabetes.

BACKGROUND: Diabetes mellitus (DM) is the most common metabolic disorder in pregnancy. Women with Type 2 DM seems to have no better perinatal outcomes than those with Type 1 DM. METHODS: Single-center prospective cohort observational study. Pregnant women with diabetes (141 with Type 1 DM and 124 with Type 2 DM) that were followed in the university hospital between 2009 and 2021 were included in this study. Clinical data and obstetric and perinatal outcomes were collected. RESULTS: As expected, women with Type 1 DM were younger and had a longer duration of diabetes than women with Type 2 DM. Obesity and chronic hypertension were higher in the group of women with Type 2 DM and their value of HbA1c in the second and third trimesters were lower than in Type 1 DM. No differences in prematurity were found, but more extreme prematurity was observed in Type 2 DM, as well as a higher rate of congenital malformations. The frequency of hypoglycemia and the weight of the newborn was higher in Type 1 DM. The maternal independent factors related to the weight of the newborn were: the glycemic control at the third trimester, the weight gain during pregnancy, and pregestational BMI. CONCLUSIONS: Newborns born to mothers with Type 1 DM were larger and had a higher frequency of hypoglycemia, while congenital malformations and precocious preterm was more associated to Type 2 DM. Metabolic control, weight gain and pregestational weight were important determinants of both obstetric and neonatal complications.

Transcriptomic and lipidomic analysis of the differential pathway contribution to the incorporation of erucic acid to triacylglycerol during Pennycress seed maturation.

Thlaspi arvense (Pennycress) is an emerging feedstock for biofuel production because of its high seed oil content enriched in erucic acid. A transcriptomic and a lipidomic study were performed to analyze the dynamics of gene expression, glycerolipid content and acyl-group distribution during seed maturation. Genes involved in fatty acid biosynthesis were expressed at the early stages of seed maturation. Genes encoding enzymes of the Kennedy pathway like diacylglycerol acyltransferase1 (TaDGAT1), lysophosphatidic acid acyltransferase (TaLPAT) or glycerol 3-phosphate acyltransferase (TaGPAT) increased their expression with maturation, coinciding with the increase in triacylglycerol species containing 22:1. Positional analysis showed that the most abundant triacylglycerol species contained 18:2 at sn-2 position in all maturation stages, suggesting no specificity of the lysophosphatidic acid acyltransferase for very long chain fatty acids. Diacylglycerol acyltransferase2 (TaDGAT2) mRNA was more abundant at the initial maturation stages, coincident with the rapid incorporation of 22:1 to triacylglycerol, suggesting a coordination between Diacylglycerol acyltransferase enzymes for triacylglycerol biosynthesis. Genes encoding the phospholipid-diacylglycerol acyltransferase (TaPDAT1), lysophosphatidylcholine acyltransferase (TaLPCAT) or phosphatidylcholine diacylglycerolcholine phosphotransferase (TaPDCT), involved in acyl-editing or phosphatidyl-choline (PC)-derived diacylglycerol (DAG) biosynthesis showed also higher expression at the early maturation stages, coinciding with a higher proportion of triacylglycerol containing C18 fatty acids. These results suggested a higher contribution of these two pathways at the early stages of seed maturation. Lipidomic analysis of the content and acyl-group distribution of diacylglycerol and phosphatidyl-choline pools was compatible with the acyl content in triacylglycerol at the different maturation stages. Our data point to a model in which a strong temporal coordination between pathways and isoforms in each pathway, both at the expression and acyl-group incorporation, contribute to high erucic triacylglycerol accumulation in Pennycress.

Barriers and facilitators in self-care and management of chronic kidney disease in dialysis patients: A systematic review of qualitative studies.

AIM: To identify and synthesise qualitative studies on barriers and facilitators perceived by dialysis patients in relation to self-care and disease management. DESIGN: Systematic review of qualitative studies. DATA SOURCES: Qualitative study articles were extracted from PUBMED, MEDLINE, COCHRANE, WEB OF SCIENCE (WOS), CINAHL PsycINFO and EMBASE and electronic journals of the Spanish Society of Nephrology and Spanish Society of Nephrological Nursing until May 2022. Studies on barriers and/or facilitators affecting self-care and disease management expressed by people undergoing haemodialysis or peritoneal dialysis were included. REVIEW METHODS: The SPICE (Setting, Perspective, Intervention, Comparison and Evaluation) strategy was used to develop issues and subissues through the thematic synthesis of the qualitative findings. GRADE-CERQual was used to evaluate the articles. RESULTS: From 172 articles, 15 qualitative articles about barriers and facilitators perceived by patients concerning self-care and disease management were finally included. Identified eight facilitators and four barriers. CONCLUSION: Patients perceived a significant number of barriers and facilitators. It is possible to identify which aspects facilitate self-management of their disease and to understand that the processes are individualised. This is why therapeutic strategies should be designed to foster the participation and empowerment of the person in the management of the disease. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: Identifying the barriers and facilitators concerning the management of chronic kidney disease furnishes us with knowledge for individualised clinical practice and improved care processes. IMPACT: This review is the first to synthesise barriers and facilitators in haemodialysis patients about the management of their disease and treatment. The results enable the proposal of improvements in the training of healthcare personnel, clinical practice guidelines and action protocols to improve the daily life and management of the disease by patients. No patient or public contribution due to this is a systematic review.

Gestación tras cáncer / Pregnancy after cancer

El embarazo o el deseo gestacional en personas con antecedentes oncológicos son situaciones clínicas de frecuencia creciente que requieren un abordaje global. El consejo preconcepcional es básico en estos casos, y debe incluir una valoración conjunta y una coordinación multidisciplinar entre los especialistas de oncología o del proceso de base, de fertilidad o reproducción, y obstetricia o medicina maternofetal. El objetivo de esta valoración incluye consensuar el momento óptimo para asumir una gestación de forma segura sin empeorar el pronóstico de su enfermedad y planificar el seguimiento de la gestación de acuerdo con las posibles complicaciones maternas o perinatales. En la presente revisión se detallan los aspectos reproductivos más relevantes de tres de los tipos de cáncer más frecuentes en la edad reproductiva: el cáncer de mama, el cáncer de cérvix y los cánceres hematológicos.(AU)

Pregnancy or reproductive desire in people with a previous cancer represents a clinical situation of increasing frequency that requires a global approach. Preconceptional counseling is mandatory in these cases and should include a global assessment and multidisciplinary coordination between specialists in oncology, fertility and obstetrics or maternal-fetal medicine. The objective of this assessment includes determining the optimal time-to-pregnancy safe for the mother, without worsening the prognosis of the disease and planning the pregnancy follow-up according to possible maternal or perinatal complications. This review details the most relevant reproductive aspects of three of the most frequent types of cancer during reproductive age: breast cancer, cervical cancer and hematological cancers.(AU)

Effect of a nutritional intervention based on an energy-reduced Mediterranean diet on environmental impact.

OBJECTIVE: To estimate the environmental impact of a dietary intervention based on an energy-reduced Mediterranean diet (MedDiet) after one year of follow-up. METHODS: Baseline and 1-year follow-up data were used for 5800 participants aged 55-75 years with metabolic syndrome in the PREDIMED-Plus study. Food intake was estimated through a validated semiquantitative food consumption frequency questionnaire, and adherence to the MedDiet was estimated through the Diet Score. Using the EAT-Lancet Commission tables we assessed the influence of dietary intake on environmental impact (through five indicators: greenhouse gas emissions (GHG), land use, energy used, acidification and potential eutrophication). Using multivariable linear regression models, the association between the intervention and changes in each of the environmental factors was assessed. Mediation analyses were carried out to estimate to what extent changes in each of 2 components of the intervention, namely adherence to the MedDiet and caloric reduction, were responsible for the observed reductions in environmental impact. RESULTS: We observed a significant reduction in the intervention group compared to the control group in acidification levels (-13.3 vs. -9.9 g SO2-eq), eutrophication (-5.4 vs. -4.0 g PO4-eq) and land use (-2.7 vs. -1.8 m2). Adherence to the MedDiet partially mediated the association between intervention and reduction of acidification by 15 %, eutrophication by 10 % and land use by 10 %. Caloric reduction partially mediated the association with the same factors by 55 %, 51 % and 38 % respectively. In addition, adherence to the MedDiet fully mediated the association between intervention and reduction in GHG emissions by 56 % and energy use by 53 %. CONCLUSIONS: A nutritional intervention based on consumption of an energy-reduced MedDiet for one year was associated with an improvement in different environmental quality parameters.

Evaluation of effectiveness of an art-based museum intervention in reducing loneliness among older adults (ArtGran): a quasi-experimental study.

OBJECTIVES: Loneliness is a public health issue among older adults. We designed an intervention offering 10 sessions with diverse artistic methods (ArtGran). This study assessed the effectiveness of ArtGran in reducing loneliness and its negative effects on health in community-dwelling older adults in 2022 in Barcelona. STUDY DESIGN: Quasi-experimental study, with an intervention group (IG) and a comparison group (CG). METHODS: The sample included residents aged ≥70 years from 6 selected neighbourhoods of Barcelona. In each neighbourhood, an IG and a CG was formed with participants who reported loneliness and without special mobility needs. The participants were referred from primary care centres, social services, and community health centres. We included 138 participants (IG = 63, CG = 75). We collected data on loneliness, quality of life (QoL-5D), mood, and self-perceived health before and after the intervention through validated questionnaires. To assess the effect of the intervention, we built Poisson models with robust variance and linear regression models. RESULTS: At the end of the intervention, participants in the IG were more likely than those in the CG to be able to perform their usual activities without problems (adjusted prevalence ratio [aPR] = 1.22; 95% confidence interval [CI]: 1.02-1.45). Compared with the CG, participants in the IG attending more than half of the sessions had lower levels of loneliness (aPR = 1.36; 95%CI: 1.07-1.73), a better ability to perform their usual activities (aPR [95%CI] = 1.24 [1.05-1.48]), and higher happiness scores (ß = 0.73; P = 0.01). CONCLUSIONS: The effectiveness of the intervention was more pronounced when participants had high attendance. Our results suggest that high attendance of the ArtGran program was helpful in shielding older individuals from loneliness, fostering positive moods, and preserving their functional status.

Impact of mediterranean diet promotion on environmental sustainability: a longitudinal analysis.

OBJECTIVE: This article aims to estimate the differences in environmental impact (greenhouse gas [GHG] emissions, land use, energy used, acidification and potential eutrophication) after one year of promoting a Mediterranean diet (MD). METHODS: Baseline and 1-year follow-up data from 5800 participants in the PREDIMED-Plus study were used. Each participant's food intake was estimated using validated semi-quantitative food frequency questionnaires, and the adherence to MD using the Dietary Score. The influence of diet on environmental impact was assessed through the EAT-Lancet Commission tables. The influence of diet on environmental impact was assessed through the EAT-Lancet Commission tables. The association between MD adherence and its environmental impact was calculated using adjusted multivariate linear regression models. RESULTS: After one year of intervention, the kcal/day consumed was significantly reduced (-125,1 kcal/day), adherence to a MD pattern was improved (+0,9) and the environmental impact due to the diet was significantly reduced (GHG: -361 g/CO2-eq; Acidification:-11,5 g SO2-eq; Eutrophication:-4,7 g PO4-eq; Energy use:-842,7 kJ; and Land use:-2,2 m2). Higher adherence to MD (high vs. low) was significantly associated with lower environmental impact both at baseline and one year follow-up. Meat products had the greatest environmental impact in all the factors analysed, both at baseline and at one-year follow-up, in spite of the reduction observed in their consumption. CONCLUSIONS: A program promoting a MD, after one year of intervention, significantly reduced the environmental impact in all the factors analysed. Meat products had the greatest environmental impact in all the dimensions analysed.

Development of functional consortia for the pretreatment of compostable lignocellulosic waste: A simple and effective solution to a large-scale problem.

Microorganisms drive the degradation of organic matter thanks to their enzymatic versatility. However, the structure of lignocellulose poses a great challenge for the microbiota inhabiting a compost pile. Our purpose was to increase the biodegradability of vegetable waste in the early stages of the composting process by applying a microbial consortium with lignocelllulolytic capacity. For this, a previous screening was performed among the culturable microbiota from different composting processes to find inoculants with ligninocellulolytic activity. Selected strains were applied as a pure culture and as a microbial consortium. The starting material was composed of tomato plant and pruning remains mixed in a ratio (50:50 v/v), whose humidity was adjusted to around 65%. To determine the ability of both treatments to activate the biodegradation of the mixtures, moisture, organic matter, ash, C/N ratio, 4-day cumulative respirometric index (AT4) and degradation rates of cellulose, hemicellulose and lignin were evaluated. Subsequently, a real composting process was developed in which the performance of the microbial consortium was compared with the composting process without inoculum (control). According to our tests, three microbial strains (Bacillus safensis, Bacillus licheniformis and Fusarium oxysporum) were selected. The results showed that the application of the bacteria strains at low doses (104 CFU g-1 on the complete residual material of the pile) resulted in higher rates of lignocelullose degradation after 10 days of treatment compared to that observed after application of the fungus in pure culture or untreated controls. The implementation of the strategy described in this work resulted in obtaining compost with better agronomic quality than the uninoculated controls. Therefore, the application of this consortium could be considered as an interesting tool for bioactivation of lignocellulosic waste prior to the composting process.

Bellwethers of change: population modelling of North Pacific humpback whales from 2002 through 2021 reveals shift from recovery to climate response.

For the 40 years after the end of commercial whaling in 1976, humpback whale populations in the North Pacific Ocean exhibited a prolonged period of recovery. Using mark-recapture methods on the largest individual photo-identification dataset ever assembled for a cetacean, we estimated annual ocean-basin-wide abundance for the species from 2002 through 2021. Trends in annual estimates describe strong post-whaling era population recovery from 16 875 (± 5955) in 2002 to a peak abundance estimate of 33 488 (± 4455) in 2012. An apparent 20% decline from 2012 to 2021, 33 488 (± 4455) to 26 662 (± 4192), suggests the population abruptly reached carrying capacity due to loss of prey resources. This was particularly evident for humpback whales wintering in Hawai'i, where, by 2021, estimated abundance had declined by 34% from a peak in 2013, down to abundance levels previously seen in 2006, and contrasted to an absence of decline in Mainland Mexico breeding humpbacks. The strongest marine heatwave recorded globally to date during the 2014-2016 period appeared to have altered the course of species recovery, with enduring effects. Extending this time series will allow humpback whales to serve as an indicator species for the ecosystem in the face of a changing climate.

[Translated article] Type III acromioclavicular dislocation: Mid term results after operative and non-operative treatment.

INTRODUCTION: Controversy exists in the literature about the best treatment for type III acromioclavicular dislocations. The aim of this study is to compare functional results between surgical and conservative treatment in type III acromioclavicular joint dislocations. MATERIAL AND METHOD: We retrospectively evaluated the records of 30 patients from our area with acute type III acromioclavicular dislocations that were treated from January 1st, 2016 to December 31st, 2020. Fifteen patients were treated surgically and 15 conservatively. Follow-up mean time was 37.93 months in operative group and 35.73 months in non-operative group. Results obtained on the Constant score was the main variable analysed and results obtained on the Oxford score and the Visual Analogue Scale for pain were the secondary variables. Epidemiological variables were analysed, as well as range of mobility in injured shoulder and subjective and radiological variables (distance between the superior border of the acromion and the superior border of the clavicle's distal end and presence of osteoarthritis in the acromioclavicular joint). RESULTS: Functional evaluation scores did not show differences between the two groups (Constant: operative 82/non-operative 86.38, p 0.412; Oxford: operative 42/non-operative 44.80, p 0.126) nor did Visual Analogue Scale (operative 1/non-operative 0.20, p 0.345). Subjective evaluation of the injured shoulder was excellent or good in 80% of the patients in both groups. Measurement of the distance between the superior border of the acromion and the superior border of the clavicle's distal end were significantly higher in non-operative group (operative 8.95/non-operative 14.21, p 0.008). CONCLUSIONS: Although radiographic results were better in the surgical treatment group, functional evaluation scores did not show significant differences between the two groups. These results do not support the routine use of surgical treatment for grade III acromioclavicular dislocations.

Marinade injection of pork as a possible technological strategy to reduce boar taint: Response and attitude of the consumer.

Sensory evaluation by consumers allows validation of a solution for the food industry to overcome boar taint and market entire male pork with high levels of boar taint considered "unfit for human consumption". One possible technological strategy for improvement is the injection marination of entire male pork to help minimise the impact of boar taint and improve its marketability. The responses of 120 regular pork consumers, to entire males with high levels of boar taint and castrated pork, both injection-marinated, were evaluated. The results showed a similar response between entire and castrated male pork regardless of sex, and the detection of unpleasant odours and flavours (as farm/animal), thus offering a new alternative to the pork sector to mask the boar taint and revalue this pork. However, it was observed that consumer information on castration and animal welfare of entire male pork is scarce, and it is important to increase their knowledge so that they can place a value on this technological strategy with entire male pork and thus increase their purchase intention.

The European intercomparison of in-vivo monitoring laboratories: the EIVIC-2020 project.

The EIVIC project was launched in 2020, and the main goal was the organisation of a European intercomparison of in-vivo monitoring laboratories dealing with direct measurements of gamma-emitting radionuclides incorporated into the body of exposed workers. This project was organised jointly by members of EURADOS Working Group 7 on internal dosimetry (WG7), the Federal Office for Radiation Protection (BfS, Germany) and the Radioprotection and Nuclear Safety Institute (IRSN, France). The objective was to assess the implementation of individual-monitoring requirements in EU Member States on the basis of in-vivo measurements and to gain insight into the performance of in-vivo measurements using whole-body counters. In this context, a total of 41 in-vivo monitoring laboratories from 21 countries, together with JRC (EC) and IAEA participated. The results were submitted in terms of activity (Bq) of the radionuclides identified inside phantoms that were circulated to all participants. The measured data were compared with reference activity values to evaluate the corresponding bias according to the standards ISO 28218 and ISO 13528. In general, the results of the different exercises are good, and most facilities are in conformity with the criteria for the bias and z-scores in the ISO standards. Furthermore, information about technical and organisational characteristics of the participating laboratories was collected to test if they had a significant influence on the reported results.
