The tuna meat is a nutritious food that possesses high content of protein, its low content of saturated fatty acids makes it a high demand food in the world. The Thunnus genus is composed of eight species, albacore (T. alalunga), bigeye (T. obesus), long tail tuna (T. tonggol), yellowfin tuna (T. albacares), pacific bluefin tuna (T. orientalis), bluefin tuna (T. maccoyii), Atlantic bluefin tuna (T. thynnus) and blackfin tuna (T. atlanticus). The blackfin tuna (BFT) (Thunnus atlanticus) represent the smallest species within the Thunnus genus. This species inhabits the warm waters of the West Atlantic Ocean, from the shore of Massachusetts in the north, to Rio De Janeiro in Brazil. The first objective of this study was to evaluate the nutritional composition of BFT captured in the Gulf of Mexico, we determined ash, moisture, fat, protein and carbohydrates in BFT muscle and compared the obtained data with the nutritional reports from commercial tuna species including yellowfin tuna, Atlantic bluefin tuna and salmon (Salmo salar).Secondly, we report the genetic diversity and genetic differentiation of BFT within its geographical distribution range using the Cytochrome Oxidase I (COI) and control region sequenced data and from specimens collected in the Gulf of Mexico. We observed a nucleotide diversity π=0.001, 24 segregating sites and 10 parsimony informative. Within the CR we found nine different haplotypes π=0.044, 39 segregating sites, 16 parsimony informative sites. We concluded that according with the haplotype distribution there are differences among the BFT from the Gulf of Mexico and the North Atlantic compared to the South Atlantic. The Caribbean Sea is a migration point of the BFT, where all except the South Atlantic haplotypes were found.

- Abstract
At least half the population in industrialized countries suffers from obesity due to excessive accumulation of adipose tissue. Recently, rice ( Oryza sativa ) proteins have been considered valuable sources of bioactive peptides with antiadipogenic potential. In this study, the digestibility and bioaccessibility in vitro of a novel protein concentrate (NPC) from rice were determined through INFOGEST protocols. Furthermore, the presence of prolamin and glutelin was evaluated via SDS-PAGE, and their potential digestibility and the bioactivity of ligands against peroxisome proliferator-activated receptor gamma (PPARγ) were explored by BIOPEP UWM and HPEPDOCK. For the top candidates, molecular simulations were conducted using Autodock Vina to evaluate their binding affinity against the antiadipogenic region of PPARγ and their pharmacokinetics and drug-likeness using SwissADME. Simulating gastrointestinal digestion showed a recovery of 43.07% and 35.92% bioaccessibility. The protein banding patterns showed the presence of prolamin (57 kDa) and glutelin (12 kDa) as the predominant proteins in the NPC. The in silico hydrolysis predicts the presence of three and two peptide ligands in glutelin and prolamin fraction, respectively, with high affinity for PPARγ (≤160). Finally, the docking studies suggest that the prolamin-derived peptides QSPVF and QPY (-6.38 & -5.61 kcal/mol, respectively) have expected affinity and pharmacokinetic properties to act as potential PPARγ antagonists. Hence, according to our results, bioactive peptides resulting from NPC rice consumption might have an antiadipogenic effect via PPARγ interactions, but further experimentation and validation in suitable biological model systems are necessary to gain more insight and to provide evidence to support our in silico findings.

- Abstract
Fava bean ( Vicia faba L.) is a high-protein crop consumed worldwide and is an exceptional plant-based protein source for human consumption. The present study evaluated in vitro nutritional properties of four different protein flours of fava bean: minimal processed flour (MPF), cooked flour (CF), non-polyphenol protein concentrate (NPP), and polyphenol-protein concentrate (PP). NPP showed the highest protein concentration of 94.39 ± 0.76%. The heat treatment significantly increased the in vitro protein digestibility in CF (94.15 ± 2.45%). NPP and PP showed the highest bioaccessibility, 29.85 ± 1.88 and 33.19 ± 1.65%, respectively, no significant differences. SDS-PAGE analysis revealed bioaccessible low molecular weight peptides (<15 kDa) and legumin and vicilin presence. In silico analysis of bioactive peptides of legumin and vicilin presented high occurrence frequencies of bioactivities, as angiotensin-converting enzyme-inhibitor and dipeptidyl peptidase III/IV inhibitor peptides. This study supports the use and further investigation of fava bean proteins for human nutrition., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2022 The Authors.)

- Abstract
Legumes are associated with gut health benefits, and increasing evidence indicates that their consumption reduces the risk of chronic diseases that include autoimmunity. Beans are rich sources of compounds with health-promoting effects, and recent metabolomic approaches have enabled the comprehensive characterization of the chemical composition of Vicia faba L. This article reviewed whether the phytocompounds in broad beans might modulate the aryl hydrocarbon receptor (AhR), which plays an essential role in autoantigen tolerance as a potential dietary strategy for autoimmune disease management. Therefore, thirty molecules present in Vicia faba of the chemical classes of flavonoids, chalcones, stilbenes, jasmonates, alkaloids, and amino acids, and either a human- or microbiome-derived product of biotransformation, retrieved from the literature or predicted in silico were evaluated by docking for affinity against the ligand-binding domain of AhR. Most analyzed compounds showed high affinity even after their metabolism which indicate that some AhR modulators remain active despite several steps in their biotransformation. Hence, our results suggest that in similitude with the gut metabolism of the tryptophan, phytocompounds mainly polyphenols also lead to metabolites that induce the AhR pathway. Furthermore, wyerone acid, wyerone epoxide, jasmonic acid, stizolamine, vicine, and convicine and their metabolite derivatives are reported for the first time as potential AhR ligands. Overall, chronic consumption of phytochemicals in Vicia faba L. and their gut biotransformation may protect against autoimmune disease pathogenesis by AhR modulation., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Méndez-López, Sosa de León, López-Cabanillas Lomelí, González-Martínez and Vázquez-Rodríguez.)

- Abstract
Though not exempt from adverse events, azathioprine (AZA) is an inexpensive and effective drug in the induction and maintenance treatment of patients with inflammatory bowel disease. We present the case of a 20-year-old female patient with left-side ulcerative colitis in whom AZA was started at a dose of 1.5 mg/kg/day due to dependence on corticoids (thiopurine methyltransferase activity: 14.9 U/mL). Two weeks after starting treatment she began to report excessive hair loss, resulting in an almost complete loss of scalp hair.

- Abstract
The tepary bean ( Phaseolus acutifolius Gray) is a US-Mexico frontier native crop, produces high yields in agriculture, and needs to be reconsidered because of its nutritional and functional properties. This study aimed to determine the technological and nutritional properties of flours and protein concentrates of tepary bean, besides determining an in silico agonist effect of tepary bean lectin to peroxisome proliferator-activated receptor gamma (PPAR-γ). We evaluated the technological properties of raw samples (tepary flour and tepary protein concentrate) and cooked samples (tepary flour and tepary protein concentrate). The flours present a significant difference ( p < 0.05) concerning protein concentrates in water absorption and oil absorption capacity. The raw samples' emulsifying capacity was higher than that reported in the literature for other legumes, but not the cooked samples. The samples' foaming capacity had no significant difference in treatments ( p > 0.05), and cooked tepary bean protein concentrate presented complete gelation at a lower concentration (2%). Nutritionally, raw samples present a protein percentage of 23.46 ± 0.06 and 71.38 ± 0.44 and cooked samples present a protein percentage of 25.27 ± 0.04 and 62.69 ± 0.14; a chemical score of 72, 86, 82, and 72; in vitro protein digestibility (%) = 48.20 ± 0.31, 49.80 ± 0.80, 61.77 ± 1.70, and 63.61 ± 4.19; and C-PER = 0.86, 1.34, 1.93, and 1.81, respectively. All the samples showed methionine + cysteine as the limiting amino acid. All these nutritional data are very similar to the common bean ( Phaseolus vulgaris ). SDS-PAGE preserves the lectin fraction in both protein concentrates. The in silico study of tepary lectin (PDB: 6tt9) shows that there were seven peptides that presented values below -120 kcal/mol: PEW, VSVGF, PSQK, TTPW, ATSF, ITY, and TSF, with VSVGF, PSQK, and PEW having the highest affinity for active sites of the PAPRγ receptor (binding energies from -5.32 to -7.04 kcal/mol). These peptides could show antiadipogenic or antidiabetic activity based on the intermolecular bond energies and open an interesting research item., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 López-Ibarra, Ruiz-López, Bautista-Villarreal, Báez-González, Rodríguez Romero, González-Martínez, López-Cabanillas Lomelí and Vázquez-Rodríguez.)

- Abstract
Although digestive endoscopy is considered to be a safe procedure, both the growing complexity of the techniques and the underlying diseases of patients increase the risk of adverse events during the procedure. Cardiorespiratory events are the most frequent complications, and can occur in patients with or without sedation, although they appear more often when the patient is sedated. The body's physiological response to stress is what causes these adverse events, which are generally mild and transient, although they can be serious. They are more frequent in patients with cardiopulmonary diseases, which logically increase risk. The autonomic nervous system, through its sympathetic and parasympathetic branches, is primarily responsible for these alterations. Patients with asthma or chronic obstructive pulmonary disease have a higher risk of hypoxemia, bronchospasm, and arrhythmia during the endoscopic procedure. Patients with arrhythmia and ischemic heart disease have a higher risk of myocardial ischemia and heart rhythm disturbances. The risk of adverse events during the procedure can be reduced by reviewing the patient's medical history along with a basic clinical examination before endoscopy. A brief interrogation about symptom control can also help the safety of endoscopy.

- Abstract
Percutaneous endoscopic gastrostomy (PEG) is an effective and safe method for nutritional support in patients with malnutrition and impossibility of oral intake with an estimated survival higher than the months that require enteral nutrition beyond four weeks. The main indications include neoplasms of the upper air-digestive tract and neurological diseases, with dementia currently considered a controversial indication. Anatomical alterations and infectious diseases are the most frequent contraindications. There are different endoscopic techniques; the most widely used being the "pull" method, with a low mortality. Complications are more frequent in patients with multiple pathologies and the elderly. Wound infection, extraction of the tube, tube blockage and bronchoaspiratory pneumonia are the most prevalent complications. Adequate prior preparation of the patient and exhaustive maintenance of the tube can reduce the appearance of these., (Copyright © 2018 Elsevier España, S.L.U. All rights reserved.)

- Abstract
Introduction: Cervical cancer is the second most common cancer worldwide in women, with an annual mortality of 3.6 per 100.000 women in Spain. An opportunistic screening protocol is currently being developed in Cantabria. The objective of the study is to propose a population-based screening program in Cantabria and assess its cost-benefits., Patients and Methods: The population-based program design has been carried out according to the description of the natural course of cervical cancer and its incidence and mortality in Cantabria during 2000-2009. There have been some proposals to increase participation in the program and to evaluate its quality. Costs and benefits (direct and indirect) have been analyzed in several scenarios by modifying the frequency of tests (3-5 years), the age at which the program can be accessed (21, 25 or 30 years), the coverage of the program (60-80%), and discount rates (0-3-6%)., Results: A program carried out with coverage of 80% and tests performed every 3 years generates annual costs of €893.000 (discount rate of 3%) compared to the current opportunistic protocol. Scenarios with tests performed every 5 years generate an annual benefit higher than €618.000, depending on the age of accessing the program., Conclusions: Scenarios with coverage lower than 60% or with women over 30 years old having access to the program are not of interest because of the lower health benefits. However, performing tests every 5 years is more economically advantageous than every 3 years, with similar health benefits., (Copyright © 2013 Sociedad Española de Médicos de Atención Primaria (SEMERGEN).

- Abstract
Objective: To analyze cervical cancer screening performed in Cantabria by evaluating the coverage and costs of screening and by calculating the available direct costs of the disease and the indirect costs of cervical cancer mortality., Methods: Screening for cervical cancer is performed in women aged between 21 and 65. According to the census for 2011 in Cantabria, there were 189.111 women in this age group. We performed a cross sectional, quantitative and qualitative study of the Pap smears performed and analyzed the direct and indirect costs of cervical cancer., Results: Between 2006 and 2011, 51% of women studied had one Pap smear, and 26% had two. In 2011, 31.554 Pap smears were performed in opportunistic screening in Cantabria, and the direct cost was 2,904.760 €. The annual direct cost of cervical cancer (average 2008-2010) was 567.567 €. The annual indirect costs (average 2001-2008) of cervical cancer was 386.122.02 €, in the reference scenario considered., Conclusions: Only 26% of women in Cantabria attended screening within the intervals recommended in the current opportunistic protocol. The cost data provided in this study may be useful for future economic evaluations., (Copyright © 2013 SESPAS. Published by Elsevier Espana. All rights reserved.)
