RESUMO

This pilot study evaluated the impact of pistachio consumption on cognitive performance and mood in overweight young adults. Pistachios were characterized (chemical and nutraceutical), and a baseline-final, uncontrolled nutritional intervention was performed (28 g of pistachio/28 days). Psychometric tests were applied to estimate cognitive performance and mood; anthropometric evaluation, biochemical analysis, and plasma antioxidant activity were included. The main component of nuts was lipids (48.1%). Pistachios consumption significantly (p ≤ 0.05) reduced waist circumference (-1.47 cm), total cholesterol (-10.21 mg/dL), LDL (-6.57 mg/dL), and triglycerides (-21.07 mg/dL), and increased plasma antioxidant activity. Pistachio supplementation improved risk tolerance (p ≤ 0.006) and decision-making strategy (p ≤ 0.002; BART-task), executive functions (BCST-task; p ≤ 0.006), and selective and sustained attention (Go/No-Go-test; p ≤ 0.016). The mood state was positively modulated (p ≤ 0.05) for anxiety, anger-hostility, and sadness-depression. These results show for the first time the benefits of pistachio consumption on cognitive performance and mood in overweight young adults.

RESUMO

BACKGROUND: Infections by dengue virus (DENV) and Zika virus (ZIKV) have some similar symptoms and a cross-reactive immune response, although with different risk populations and outcomes. Here, we evaluated the virological characteristics and the nonstructural protein 1 (NS1)-specific antibody responses to DENV and ZIKV in children suspected of dengue in different epidemiological moments in Colombia. METHODS: Viral RNA, circulating NS1 and IgM/IgG specific for DENV and ZIKV were performed by reverse transcription-quantitative polymerase chain reaction and enzyme-linked immunosorbent assay (ELISA) in 301 children suspected of dengue enrolled in a hospital setting during the ZIKV epidemic and a primary healthcare setting during a DENV epidemic. For the detection of DENV and ZIKV-specific IgM, an NS1-based ELISA was validated using characterized pediatric samples. Clinical and laboratory parameters were also evaluated. RESULTS: DENV RNA or NS1 antigen was detected in the plasma of 62% of children, and in none, the ZIKV RNA was found. NS1-based ELISA for DENV and ZIKV IgM showed a sensitivity/specificity of 90/84% and 73/98%, respectively. Of 114 children without detectable viremia or antigenemia, 30.7%, 17.5%, 22% and 30% were IgM-DENV+, IgM-ZIKV+, IgM-DENV+ZIKV+ and IgM-DENV-ZIKV-, respectively. The ZIKV/DENV IgM-NS1 ratio allows the identification of the infecting ortho flavivirus in 88% of the children with IgM-DENV+ZIKV+, confirming a high predominance of DENV infections in the 2 pediatric settings. CONCLUSION: Overall, 88% of the children with clinical suspicion of dengue had an identifiable ortho flaviviral infection, with 80% caused by DENV, 7% by ZIKV and 0.7% classified as recent infections or coinfection, demonstrating active viral cocirculation in the pediatric population of southern Colombia. The IgM-NS1 detection improved the identification of ortho flaviviral infections in children without viremia or antigenemia, suggesting it is a helpful complementary tool for medical personnel in tropical regions with high viral cocirculation and different clinical scenes.

RESUMO

Background: Suicide is a public health problem, which has increased in recent years, becoming a serious cause of mortality, mostly in low- and middle-income countries. Suicidal behavior is infrequent before adolescent years, various related factors have been described. The purpose of this work is to describe the case of a patient in school age who attempted suicide and the identified factors that might have contributed. Clinical case: Nine-year-old male attempted suicide by hanging in the bathroom, endangering his life. He received emergency attention and hospitalized in intensive care. During his hospitalization, the mental health service approached him. Amongst the factors previously associated with suicidal intent during school age and identifiable in the patient are family disintegration, symptoms of major depression episodes, reading-related learning difficulties and attention deficit hyperactivity disorder. The patient received treatment and follow up consultation, without showing any suicidal behavior up to this date. The patient is currently 13 years old. Conclusions: It must be recognized that children of school age can present suicidal behavior. It is important to acknowledge the factors associated with this kind of behavior, to reduce risks and provide an opportune attention and handling.


Introducción: el suicidio es un problema de salud pública que se ha incrementado en los últimos años, convirtiéndose en una grave causa de mortalidad principalmente en países de ingresos bajos y medios. Las conductas suicidas son poco frecuentes antes de la adolescencia, por lo que se han descrito diversos factores relacionados. El propósito de este trabajo es describir el caso de un paciente en edad escolar que intentó suicidarse y las causas identificadas que pudieron influir. Caso clínico: paciente masculino de nueve años puso su vida en riesgo al intentar suicidarse por ahorcamiento en el cuarto de baño. Recibió atención de urgencia y estuvo en la terapia intensiva. Durante su hospitalización fue abordado por el servicio de salud mental. Entre los factores que han sido previamente asociados al intento suicida en la edad escolar que pudieron identificarse en el paciente se encuentran: desintegración familiar, síntomas de episodio depresivo grave, dificultad en el aprendizaje para la lectura y un trastorno por déficit de atención con hiperactividad. El paciente recibió tratamiento y seguimiento, hasta el día de hoy no ha vuelto a presentar comportamientos suicidas. Actualmente tiene trece años. Conclusiones: se debe reconocer que los niños en edad escolar pueden presentar comportamientos suicidas, y es importante conocer los factores asociados a este tipo de conductas. Esto, con la finalidad de poder reducir el riesgo, así como otorgar atención y manejo de forma oportuna.

RESUMO

The current conservation status of Percichthys trucha (Creole perch) is Least Concern, although the population trend is considered to be decreasing. We conducted an extensive survey of parasite fauna in this species over two decades in its distribution range in Argentina. Fish were collected using gill and trawl nets. Parasites were collected, identified, and counted to calculate prevalence and mean intensity. The present work reports the parasite species infecting P. trucha, using data from our own survey and from previously published records. This information enables us to evaluate infection and distribution patterns, assess the role of P. trucha as host, determine the specificity of the parasites, and evaluate the threat represented by introduced, invasive parasites. The data set consists of a total of 453 host-parasite-locality records, of which only 15 are exclusively bibliographic. We found 44 parasite taxa: 19 digeneans, 4 monogeneans, 5 cestodes, 8 nematodes, 4 acanthocephalans, 3 crustaceans, and 1 mollusk. The most represented families were Diplostomidae, Heterophyidae, and Dactylogyridae. This study increases the number of parasite species known from 25 to 44. It can be concluded that this parasite fauna is characterized by high diversity, particularly of digeneans, and most of the parasites reproduce within this host, a pattern which is related to the top position of this fish species in the trophic webs. Six parasite species (Allocreadium patagonicum, Homalometron papilliferum, Acanthostomoides apophalliformis, Duplaccessorius andinus, Pseudodelphys limnicola, and Hysterothylacium patagonense) exhibit high host specificity (only matures in Creole perches) and are widely distributed, which could now be considered as "biogeographical core helminth fauna." Some P. trucha populations are affected by the invasion of alien fishes like Cyprinus carpio and pathogenic parasites like Lernaea cyprinacea and Schizocotyle acheilognathi. Our findings emphasize the need for further research.

RESUMO

Many neurological disorders have a distinctive colonic microbiome (CM) signature. Particularly, children with autism spectrum disorders (ASD) exhibit a very dissimilar CM when compared to neurotypical (NT) ones, mostly at the species level. Thus far, knowledge on this matter comes from high-throughput (yet very expensive and time-consuming) analytical platforms, such as massive high-throughput sequencing of bacterial 16S rRNA. Here, pure (260/280 nm, ~1.85) stool DNA samples (200 ng.µL-1) from 48 participants [39 ASD, 9 NT; 3-13 y] were used to amplify four candidate differential CM markers [Bacteroides fragilis (BF), Faecalibacterium prausnitzii (FP), Desulfovibrio vulgaris (DV), Akkermansia muciniphila (AM)], using micro-organism-specific oligonucleotide primers [265 bp (BF), 198 bp (FP), 196 bp (DV), 327 bp (AM)] and a standardized two-step [low (step 1: °Tm-5 °C) to high (stage 2: °Tm-0 °C) astringent annealing] PCR protocol (2S-PCR). The method was sensitive enough to differentiate all CM biomarkers in the studied stool donors [↑ abundance: NT (BF, FP, AM), ASD (DV)], and phylogenetic analysis confirmed the primers' specificity.

RESUMO

BACKGROUND: Pediatric dengue and sepsis share clinical and pathophysiologic aspects. Multiple inflammatory and regulatory cytokines, decoy receptors and vascular permeability factors have been implicated in the pathogenesis of both diseases. The differential pattern and dynamic of these soluble factors, and the relationship with clinical severity between pediatric dengue and sepsis could offer new diagnosis and therapeutic strategies. METHODS: We evaluated the concentration levels of 11 soluble factors with proinflammatory, regulatory and vascular permeability involvement, in plasma from children with dengue or sepsis, both clinically ranging from mild to severe, in the early, late and convalescence phases of the disease. RESULTS: During early acute infection, children with sepsis exhibited specific higher concentration levels of IL-6, vascular endothelial growth factor (VEGF), and its soluble decoy receptor II (sVEGFR2) and lower concentration levels of IL-10 and the soluble tumor necrosis factor receptor 2 (sTNFR2), in comparison with children with severe dengue. In addition, the circulating amounts of soluble ST2, and VEGF/sVEGFR2 were widely associated with clinical and laboratory indicators of dengue severity, whereas secondary dengue virus infections were characterized by an enhanced cytokine response, relative to primary infections. In severe forms of dengue, or sepsis, the kinetics and the cytokines response during the late and convalescence phases of the disease also differentiate. CONCLUSIONS: Dengue virus infection and septic processes in children are characterized by cytokine responses of a specific magnitude, pattern and kinetics, which are implicated in the pathophysiology and clinical outcome of these diseases.

RESUMO

Bisphenol A (BPA) promotes colon cancer by altering the physiological functions of hormones. Quercetin (Q) can regulate signaling pathways through hormone receptors, inhibiting cancer cells. The antiproliferative effects of Q and its fermented extract (FEQ, obtained by Q gastrointestinal digestion and in vitro colonic fermentation) were analyzed in HT-29 cells exposed to BPA. Polyphenols were quantified in FEQ by HPLC and their antioxidant capacity by DPPH and ORAC. Q and 3,4-dihydroxyphenylacetic acid (DOPAC) were quantified in FEQ. Q and FEQ exhibited antioxidant capacity. Cell viability with Q+BPA and FEQ+BPA was 60% and 50%, respectively; less than 20% of dead cells were associated with the necrosis process (LDH). Treatments with Q and Q+BPA induced cell cycle arrest in the G0/G1 phase, and FEQ and FEQ+BPA in the S phase. Compared with other treatments, Q positively modulated ESR2 and GPR30 genes. Using a gene microarray of the p53 pathway, Q, Q+BPA, FEQ and FEQ+BPA positively modulated genes involved in apoptosis and cell cycle arrest; bisphenol inhibited the expression of pro-apoptotic and cell cycle repressor genes. In silico analyses demonstrated the binding affinity of Q > BPA > DOPAC molecules for ERα and ERß. Further studies are needed to understand the role of disruptors in colon cancer.

RESUMO

The estrogenic receptor beta (ERß) protects against carcinogenesis by stimulating apoptosis. Bisphenol A (BPA) is related to promoting cancer, and naringenin has chemoprotective activities both can bind to ERß. Naringenin in the colon is metabolized by the microbiota. Cancer involves genetic and epigenetic mechanisms, including miRNAs. The objective of the present study was to evaluate the co-exposure effect of colonic in vitro fermented extract of naringenin (FEN) and BPA, to elucidate molecular effects in HT-29 colon cancer cell line. For this, we quantified genes related to the p53 signaling pathway as well as ERß, miR-200c, and miR-141. As an important result, naringenin (IC50 250 µM) and FEN (IC50 37%) promoted intrinsic pathways of apoptosis through phosphatase and tensin homolog (PTEN) (+2.70, +1.72-fold, respectively) and CASP9 (+3.99, +2.03-fold, respectively) expression. BPA decreased the expression of PTEN (-3.46-fold) gene regulated by miR-200. We suggest that once co-exposed, cells undergo a greater stress forcing them to mediate other extrinsic apoptosis mechanisms associated with death domain FASL. In turn, these findings are related to the increase of ERß (5.3-fold with naringenin and 13.67-fold with FEN) gene expression, important in the inhibition of carcinogenic development.

RESUMO

Garambullo (Myrtillocactus geometrizans), endemic fruit from Mexico, contains several bioactive compounds (phenolic compounds, betalains, antioxidant fiber), highlighting it as a good functional food. In this research, the impact of the in vitro gastrointestinal digestion on phytochemical bioaccessibility from garambullo and its antioxidant capacity are studied. The fruit contained previously unidentified phytochemicals in the polar and non-polar extracts (acetone and hexane). The bioaccessibility decreased in the mouth and stomach for flavanones (up to 11.9 and 8.9%, respectively), isoflavones (up to 20.0 and 9.2%, respectively), flavonols (up to 15.2 and 15.7%, respectively), hydroxycinnamic acids (up to 21.7 and 13.1%, respectively), and betalains (up to 10.5 and 4.2%, respectively); hydroxybenzoic acids were increased (up to 752.8 and 552.6%, respectively), while tocopherols increased in the mouth (127.7%) and decreased in the stomach (up to 90.3%). In the intestinal phase, the digestible fraction showed low phytochemicals bioaccessibility, and some compounds were recovered in the non-digestible fraction. The antioxidant capacity decreased in different compartments of the gastrointestinal tract, being higher in the mouth (872.9, 883.6, 385.2, and 631.2 µmol TE per g dw by ABTS, DPPH, ORAC, and FRAP, respectively) and stomach (836.2, 942.1, 289.0, and 494.9 µmol TE per g dw ABTS, DPPH, ORAC, and FRAP, respectively). The results indicate that digestion positively or negatively affects compounds' bioaccessibility depending on their structural family, and the antioxidant capacity decreases but remains higher than other functional foods.

RESUMO

Extruded polyphenol-rich by-products like mango bagasse (MB) could be used to manufacture functional confections. However, few reports have assessed the extrusion impact on MB polyphenols within a food matrix. This research aimed to evaluate the impact of extrusion on the bioaccessibility, intestinal permeability, and antioxidant capacity of phenolic compounds (PC) from non-extruded and extruded MB-added confections (EMBC and MBC, respectively). The inhibition of 2,2-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) and 2,2-diphenyl-1-picrylhydrazyl radicals and in silico approaches were used to evaluate the antioxidant capacity. MBC displayed the highest gastric bioaccessibility (%) of xanthones and flavonoids, whereas selective release of gallic acid, mangiferin, and quercetin glucoside was shown for EMBC. Lower PC' apparent permeability coefficients were found in EMBC compared to MB (0.11 to 0.44-fold change, p < 0.05). EMBC displayed the highest antioxidant capacity by the DPPH method for the non-digestible fraction, being mangiferin the highest in silico contributor (-4 kcal/mol). Our results showed that the extrusion process helps release selective phenolics from MBC, which increases their bioaccessibility and intestinal permeability.

RESUMO

Vegetal wastes are currently a source of pollution due to the excess of organic compounds in the environment. Seeds are the main by-product of the avocado industry and represent 16-22% of the total weight and it is considered a waste without applications. Despite the seed stands out for its high content of phenolic compounds, lack of knowledge regarding of the best processing state using non-invasive and short-time methods are required to take advantage of these nutraceutical compounds. This research aimed to find correlations from physicochemical analysis, color, hardness, and firmness of the whole avocado seeds with its nutraceutical properties as long as the ripeness increased, providing information for further industrial use of this waste. The results indicated that 'Hass' avocado fruit ripening positively correlates with the improvement of the physicochemical parameters involved in the fruit processing and the increase of nutraceutical compounds in the seed. The ripeness process decreased moisture (%) and hardness (N) parameters in the seeds (27.69 and 16.4%, respectively), facilitating its processing. Moreover, the ripening increased the antioxidant capacity by DPPH* around 7%, due to the concentration of phenolic compounds in the seed. Seed's phenolic compounds were positively correlated with the Hue angle at increasing ripeness, becoming a potential physicochemical indicator for the industry. The prediction of changes in nutraceutical compounds and physicochemical properties, as ripening occurred, may reduce analysis times, processes, and guidance to use avocado seeds as a by-product. These results facilitate the seed processing and open up opportunities for its use in the industry.

RESUMO

BACKGROUND: Low back pain (LBP) is a condition with a high global prevalence, which is getting health professionals' attention, including physiotherapists as they must have the skills to provide treatment that increases the patient's quality of life. Clinical simulations could be a pedagogic strategy that facilitates adequate training for students to acquire skills to improve their professional reasoning in this clinical situation. OBJECTIVE: This study sought to determine the effects of clinical simulations with simulated patients (SP) on the physiotherapy students' clinical decision-making within a role-playing (RP) scenario while caring of LBP patients. METHODS: This experimental study included 42 participants from two Colombian universities, randomized into two groups (SP, n = 21; RP, n = 21). The clinical skill of performing the Objective Structured Clinical Examination (OSCE-LBP) was evaluated while students cared for patients with LBP; after that, a pedagogical method was conducted that included clinical simulation and, finally, the OSCE-LBP was applied again to compare both groups. RESULTS: Changes occurred in the OSCE-LBP among both groups of students: the scores increased (0.66 and 0.59 in RP and SP, respectively), and neither of the two was superior (p value 0.01; 95%CI - 0.21 to 0.23). CONCLUSION: Both types of simulation favor decision-making in professional reasoning in physiotherapy students during interactions with individuals with LBP. Trial registration https://clinicaltrials.gov/ct2/show/NCT04428892 Identifying number: NCT04428892. It was retrospectively registered.

RESUMO

Underutilized marine food products such as cephalopods' ink could be sources of bioactive compounds providing health benefits. This study aimed to assess the anti-proliferative and anti-inflammatory effects from Octopus vulgaris ink extracts (hexane-, ethyl acetate-, dichloromethane- (DM), and water extracts) using human colorectal (HT-29/HCT116) and breast (MDA-MB-231) cancer cells, and LPS-challenged murine RAW 264.7 cells. Except by ethyl-acetate, all of the extracts exhibited anti-proliferative effects without being cytotoxic to ARPE-19 and RAW 264.7 cells. Among DM fractions (F1/F2/F3), DM-F2 showed the highest anti-proliferative effect (LC50 = 52.64 µg/mL), inducing pro-apoptotic morphological disruptions in HCT116 cells. On RAW 264.7 cells, DM-F2 displayed the lowest nitrites reduction and up-regulation of key-cytokines from the JAK-STAT, PI3K-Akt, and IL-17 pathways. Compared to control, DM-F2 increased IL-4 and decreased NF-κB fluorometric expression in peripheral blood mononuclear cells (PBMCs). Metabolomic analysis of DM-F2 highlighted hexadecanoic acid and 1-(15-methyl-1-oxohexadecyl)-pyrrolidine as the most important metabolites. These compounds also exhibited high in silico binding affinity (-4.6 to -5.8 kcal/mol) to IL-1α, IL-1ß, and IL-2. Results suggested the joint immuno-modulatory and anti-proliferative effect derived from selected compounds of underutilized marine food products such as ink. This is the first report of such biological activities in extracts from O. vulgaris ink.

RESUMO

Oslerus osleri is a cosmopolitan filaroid nematode that parasitizes the respiratory system of domestic and wild canids. Natural infection by O. osleri is reported in the Andean fox (Lycalopex culpaeus) in this study. Nematodes, enclosed in small and compact fibrous nodules of 1 to 5 mm in diameter, were found on the surface of the trachea near the bronchial bifurcation on four Andean foxes during necropsy (one from Cuzco, Peru and three from Northwestern Patagonia in Argentina). The nematodes were identified as O. osleri by morphological and molecular methods. Ribosomal and mitochondrial DNA analyses were performed amplifying the second internal transcribed spacer region (ITS-2), the partial cytochrome c oxidase 1 (cox1), and the large subunit of nuclear ribosomal RNA (LSU rRNA) genes. Sequences of the ITS-2 and LSU rRNA had a genetic variation of 1.5% and 1.0%, respectively, with previous sequences of O. osleri registered in Genbank. This is the first amplification of the cox1 gene of O. osleri and demonstrated an identity of 92% to Perostrongylus falciformis (KY365437), and 90% to Angiostrongylus cantonensis (KY779735) and Angiostrongylus costaricensis (AP017675).

RESUMO

Colorectal cancer is an important concern in modern society. Risk factors such as the diet indicate the need to find healthy food products displaying additional health benefits. This study aimed to characterise and evaluate the impact of the colonic metabolites from the fermented non-digestible fraction of Moringa oleifera (MO) leaves (FNFM) on cell death mechanisms from HT-29 cells. MO leaves were digested in vitro, and the 12 h-colonic extract was obtained. FNFM mainly contained morin and chlorogenic acids (41.97 and 25.33 µg/g sample). Butyric acid was ranked as the most important metabolite of FNFM. The FNFM exerted antiproliferative effect against HT-29 colorectal cancer cells (half lethal concentration, LC50: 5.9 mL/100 mL). Compared to untreated control, LC50 increased H2O2 production (149.43%); induced apoptosis (119.02%), autophagy (75.60%), and necrosis (87.72%). These results suggested that digested MO colonic metabolites exert antiproliferative effect against HT-29 cells, providing additional health benefits associated with MO consumption.

RESUMO

V. meridionale Swartz is an underutilized Andean Berry that has been linked to several health benefits potentially derived from its anti-inflammatory effects. This research aimed to evaluate the impact of Andean Berry Juice (ABJ) combined with Aspirin in the modulation of anti-inflammatory markers from LPS-stimulated RAW 264.7 macrophages. The chemical characterization of ABJ showed a high content of polyphenols, mainly gallic acid (659-75 µg/g) and cyanidin chloride (418.61 µg/mL). Compared to LPS-stimulated macrophages, ABJ, Aspirin, and its combination reduced NO and ROS production (3.26-42.55 and 17.59-65.68%, respectively). In comparison, the half inhibitory concentration of NO reduction (IC50) was found at 7.69% v/v (ABJ) and 24.48 mM (Aspirin). Compared to the pro-inflammatory control (LPS), ABJ reduced IL-1ß, MCP-1, and GCSF; Aspirin decreased IL1R1, MCP-1, GMCSF, GCSF, and TNF-α; and the ABJ + Aspirin treatment reduced IL1R, GMCSF, and CXCL10. The in silico interaction of cytokines and the prediction of potential binding interactions suggested CCR1, CCR5, and NF-kB modulation. These results showed the anti-inflammatory potential of underutilized South American berries and their co-adjuvant effect with known drugs such as Aspirin in the resolution of inflammatory-derived conditions. This is the first report of the anti-inflammatory effects of V. meridionale Swartz juice in combination with Aspirin on LPS-challenged RAW 264.7 macrophages.
