Abstract
Introduction Pompe disease (PD) is a glycogen disorder caused by the deficient activity of acid alpha-glucosidase (GAA). We sought to review the latest available evidence on the safety and efficacy of recombinant human GAA enzyme replacement therapy (ERT) for infantile-onset PD (IOPD). Methods We systematically searched the MEDLINE (via PubMed) and Embase databases for prospective clinical studies evaluating ERT for IOPD on pre-specified outcomes. Meta-analysis was also performed. Results Of 1,722 articles identified, 16 were included, evaluating 316 patients. Studies were heterogeneous and with very low certainty of evidence for most outcomes. A moderate/high risk of bias was present for most included articles. The following outcomes showed improvements associated with alglucosidase alfa, over natural history of PD/placebo, for a mean follow-up of 48.3 months: left ventricular (LV) mass {mean change 131.3 g/m2 [95% confidence interval (CI) 81.02, 181.59]}, time to start ventilation (TSV) [HR 0.21 (95% CI: 0.12, 0.36)], and survival [HR 0.10 (95% CI: 0.05, 0.19)]. There were no differences between the pre- and post-ERT period for myocardial function and psychomotor development. Adverse events (AEs) after ERT were mild in most cases. Conclusion Our data suggest that alglucosidase alfa potentially improves LV mass, TSV, and survival in IOPD patients, with no important safety issues. Systematic Review Registration PROSPERO identifier (CRD42019123700).

Abstract
Hydroxypropyl methylcellulose (HPMC)-based microparticles and modified starch emulsions (OSA-MS) were loaded with resveratrol and characterized regarding their physicochemical and thermal properties. Both delivery systems were subject to an in vitro gastrointestinal digestion to assess the bioaccessibility of resveratrol. In addition, cell-based studies were conducted after in vitro digestion and cytotoxicity and oxidative stress were assessed. HPMC-based microparticles displayed higher average sizes (d) and lower polydispersity index (PDI) (d = 948 nm, PDI < 0.2) when compared to OSA-MS-based emulsions (d = 217 nm, PDI < 0.3). Both proved to protect resveratrol under digestive conditions, leading to an increase in bioaccessibility. Resveratrol-loaded HPMC-microparticles showed a higher bioaccessibility (56.7 %) than resveratrol-loaded emulsions (19.7 %). Digested samples were tested in differentiated co-cultures of Caco-2 and HT29-MTX, aiming at assessing cytotoxicity and oxidative stress, and a lack of cytotoxicity was observed for all samples. Results displayed an increasing antioxidant activity, with 1.6-fold and 1.4-fold increases over the antioxidant activity of free resveratrol, for HPMC-microparticles and OSA-MS nanoemulsions, respectively. Our results offer insight into physiological relevancy due to assessment post-digestion and highlight the protection that the use of micro-nano delivery systems can confer to resveratrol and their potential to be used as functional food ingredients capable of providing antioxidant benefits upon consumption.

Abstract
Studies have shown that the higher the aerobic capacity, the lower the risk of cardiovascular mortality and morbidity. In the case of cardiac patients, high-intensity interval training (HIIT) seems to be more effective than moderate-intensity continuous training (MICT) in improving aerobic capacity. The aim of this study was to investigate the effects of two community-based exercise programs using two short-term protocols (HIIT and MICT) on physical fitness and physical activity (PA) levels in coronary artery disease (CAD) patients. Methods. In this randomized controlled trial, body composition, aerobic capacity, muscle strength, and daily PA levels were assessed before and after 6 weeks of intervention in 69 patients diagnosed with CAD. All patients were randomly (1 : 1 : 1) assigned to two exercise groups (HIIT or MICT) or a control group (no exercise). Both training programs consisted of 6 weeks of supervised treadmill exercise, three sessions per week. MICT targeted ≈70-75% of peak heart rate (HR), while HIIT aimed for ≈85-95% of peak HR. The control group only followed the medical recommendations. Results. Community-based exercise programs showed more positive effects on physical fitness variables and physical activity levels compared to control. HIIT could significantly improve waist circumference, body fat mass, VO2peak, sedentary behavior, and moderate-to-vigorous PA compared to MICT. Moreover, the control group showed poorer results. Conclusion. HIIT can improve health outcomes more positively than MICT and control. These findings indicate that HIIT may be an alternative and effective training method in community-based exercise programs for CAD patients. This trial is registered with NCT03538119.

Abstract
Grape marc (GM) is an agri-food residue from the wine industry valuable for its high content of phenolic compounds. This study aimed to develop an encapsulation system for GM extract (GME) using food-grade biopolymers resistant to gastric conditions for its potential use as a nutraceutical. For this purpose, a hydroalcoholic GME was prepared with a total phenolics content of 219.62 ± 11.50 mg gallic acid equivalents (GAE)/g dry extract and 1389.71 ± 97.33 µmol Trolox equivalents/g dry extract antioxidant capacity, assessed through ABTS (2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) assay. Moreover, the extract effectively neutralized reactive oxygen species in Caco-2 cells, demonstrating an intracellular antioxidant capacity comparable to Trolox. The GME was encapsulated using whey protein isolate and pectin through nano spray drying (73% yield), resulting in spherical microparticles with an average size of 1 ± 0.5 µm and a polydispersity of 0.717. The encapsulation system protected the microcapsules from simulated gastrointestinal digestion (GID), where at the end of the intestinal phase, 82% of the initial phenolics were bioaccessible compared to 54% in the free GME. Besides, the encapsulated GME displayed a higher antioxidant activity by the ferric reducing antioxidant power assay than the free extract after GID. These results show the potential of this encapsulation system for applying GME as a nutraceutical with a high antioxidant capacity and protective effect against cellular oxidation.

Abstract
This work had as main objective to encapsulate vitamin D3 (VD3) into nanostructured lipid carriers (NLCs) using rhamnolipids as surfactant. Glycerol monostearate and medium chain triglycerides with 2.625 % of VD3 were used as lipid materials. The three formulations of NLCs with VD3 (NLCs + VD3) were composed by 99 % of aqueous phase, 1 % of lipid phase and 0.05 % of surfactant. The difference between them was the ratio of solid:liquid in lipid phase. The NLCs + VD3 sizes ranged between 92.1 and 108.1 nm. The most stable formulation maintaining their caracteristics for 60 days at 4 °C. The NLCs + VD3 cytotoxicity demonstrated that concentrations of 0.25 mg/mL or lower up had a good biocompatibility in vitro. During the in vitro digestion, formulations with lower sizes and higher content on solid lipid had higher lipolysis rate and consequently higher VD3 bioaccessibility. The rhamnolipids-based NLCs are a good option for the encapsulation of VD3.

Abstract
Herein, we review the current state-of-the-art on the use of micro- and nano-delivery systems, a possible solution to some of the drawbacks associated with the incorporation of resveratrol in foods. Specifically, we present an overview of a wide range of micro-nanostructures, namely, lipidic and polymeric, used for the delivery of resveratrol. Also, the gastrointestinal fate of resveratrol-loaded micro-nanostructures, as a critical parameter for their use as functional food, is explored in terms of stability, bioaccessibility, and bioavailability. Different micro-nanostructures are of interest for the development of functional foods given that they can provide different advantages and properties to these foods and even be tailor-made to address specific issues (e.g., controlled or targeted release). Therefore, we discuss a wide range of micro-nanostructures, namely, lipidic and polymeric, used to deliver resveratrol and aimed at the development of functional foods. It has been reported that the use of some production methodologies can be of greater interest than others, for example, emulsification, solvent displacement and electrohydrodynamic processing (EHDP) enable a greater increase in bioaccessibility. Additionally, the use of coatings facilitates further improvements in bioaccessibility, which is likely due to the increased gastric stability of the coated micro-nanostructures. Other properties, such as mucoadhesion, can also help improve bioaccessibility due to the increase in gut retention time. Additionally, cytotoxicity (e.g., biocompatibility, antioxidant, and anti-inflammatory) and possible sensorial impact of resveratrol-loaded micro- and nano-systems in foods are highlighted.

Abstract
Inflammatory bowel disease causes a major burden to patients and healthcare systems, raising the need to develop effective therapies. Technological advances in cell culture, allied with ethical issues, have propelled in vitro models as essential tools to study disease aetiology, its progression, and possible therapies. Several cell-based in vitro models of intestinal inflammation have been used, varying in their complexity and methodology to induce inflammation. Immortalized cell lines are extensively used due to their long-term survival, in contrast to primary cultures that are short-lived but patient-specific. Recently, organoids and organ-chips have demonstrated great potential by being physiologically more relevant. This review aims to shed light on the intricate nature of intestinal inflammation and cover recent works that report cell-based in vitro models of human intestinal inflammation, encompassing diverse approaches and outcomes.

Abstract
Reproducible in vitro studies of bioaccessibility, intestinal absorption, and bioavailability are key to the successful development of novel food ingredients or drugs intended for oral administration. There is currently a lack of methods that offer the finesse required to study these parameters for valuable molecules typically found in small volumes - as is the case of nanomaterials, which are often used to carry and protect bioactives. Here, we describe a modular microfluidic-based platform for total simulation of the human gastro-intestinal tract. Digestion-chips and cell-based gut-chips were fabricated from PDMS by soft lithography. On-chip digestion was validated using a fluorescently labelled casein derivative, which followed typical Michaelis-Menten kinetics and showed temporal resolution and good agreement with well-established bench-top protocols. Irreversible inhibition of serine proteases using Pefabloc® SC and a 1 : 6 dilution was sufficient to mitigate the cytotoxicity of simulated digestion fluids. Caco-2/HT29-MTX co-cultures were grown on-chip under a continuous flow for 7 days to obtain a differentiated cell monolayer forming a 3D villi-like epithelium with clear tight junction formation, and with an apparent permeability (Papp) of Lucifer Yellow closely approximating values reported ex vivo (3.7 × 10-6 ± 1.4 × 10-6vs. 4.0 × 10-6 ± 2.2 × 10-6). Digesta from the digestion-chips were flowed through the gut-chip, demonstrating the capacity to study sample digestion and intestinal permeability in a single microfluidic platform holding great promise for use in pharmacokinetic studies.

Abstract
The present study aimed to evaluate whether a 14-day period of balneotherapy influences the inflammatory status, health-related quality of life (QoL) and quality of sleep, underlying overall health state, and clinically relevant benefits of patients with musculoskeletal diseases (MD). The health-related QoL was evaluated using the following instruments: 5Q-5D-5L, EQ-VAS, EUROHIS-QOL, B-IPQ, and HAQ-DI. The quality of sleep was evaluated by a BaSIQS instrument. Circulating levels of IL-6 and C-reactive protein (CRP) were measured by ELISA and chemiluminescent microparticle immunoassay, respectively. The smartband, Xiaomi MI Band 4, was used for real-time sensing of physical activity and sleep quality. MD patients improved the health-related QoL measured by 5Q-5D-5L (p < 0.001), EQ-VAS (p < 0.001), EUROHIS-QOL (p = 0.017), B-IPQ (p < 0.001), and HAQ-DI (p = 0.019) after balneotherapy; the sleep quality was also improved (BaSIQS, p = 0.019). Serum concentrations of IL-6 were markedly decreased after the 14-day balneotherapy (p < 0.001). No statistically significant differences were observed regarding the physical activity and sleep quality data recorded by the smartband. Balneotherapy may be an effective alternative treatment in managing the health status of MD patients, with a decrease in inflammatory states, along with positive effects on pain reduction, patient's functionality, QoL, quality of sleep, and disability perception status.

Abstract
Introduction Colorectal cancer (CRC) is the second most common cancer in Portugal and worldwide, with a high mortality rate, especially in more advanced stages. In recent decades, there has been a growing interest in the distinction between right colorectal carcinoma (RCC) and left colorectal carcinoma (LCC) due to the different presentation, treatment, and prognosis. Studies show that RCC and LCC have different clinical and biological characteristics, being considered two distinct entities. Material and methods This cross-sectional, descriptive, and comparative retrospective study included data collection at the three hospitals of Beira Interior - Centro Hospitalar Cova de Beira, Hospital Amato Lusitano, and Hospital Sousa Martins - over a 6-year period. Results The proportion of RCC cases was higher. The proportion of women was higher in the RCC group compared to the LCC (46.2%, 121/262 vs. 39%, 76/195). Anemia was statistically higher in the RCC group (p <0.01). On the other hand, intestinal occlusion tends to appear in patients with LCC (p <0.001). The most frequent surgery was elective. The proportion of emergency surgery was higher in the LCC group (LCC vs RCC: 27.2% vs 18.3%; p = 0.03). Discussion and conclusion In both the RCC and LCC groups, the male sex is the most frequently observed in Beira Interior and in Portugal, opposite from the world population, in which the female sex predominates in patients with RCC. The RCC presents alterations in bowel habits more often (p> 0.05). On the other hand, anemia is more common in RCC and intestinal occlusion in LCC, following the current literature. Conducting targeted studies and optimizing the screening and treatment processes are key to reducing mortality associated with CRC.

Abstract
Cardiovascular diseases (CVD) are the leading cause of death globally. Cardiac rehabilitation (CR) programs' benefits are overall consensual; however, during exercise, progressive physiological effects have not been studied yet in cardiac patients. Our study aims to analyze physiological parameters of thermography, heart rate variability (HRV), blood pressure, central nervous system (CNS) fatigue, and cortical arousal in heart attack patients (HAP) who belong to CR programs of High-Intensity Interval Training (HIIT) and Moderate-intensity Continuous Training (MICT) compared to healthy participants. In this case control study, two HAP patients (both male, age 35 and 48, respectively) and two healthy people (both male, age 38 and 46, respectively) were randomly assigned in a 1:1:1:1 allocation ratio to one of four groups: cardiac MICT, cardiac HIIT, control MICT, and control HIIT. The HIIT at ≈85-95% of peak heart rate (HR) was followed by a one-minute recovery interval at 40% peakHR, and MICT at ≈70-75% of peakHR. Outcome measurements included thermography, HRV, blood pressure, CNS fatigue, and cortical arousal; The HAP presents more than twice the CNS fatigue in MICT than control participants, but HIIT has almost the same CNS fatigue in HAP and control. In addition, both of the HAP groups presented higher temperatures in the chest. The HIIT protocol showed better physiological responses during exercise, compared to MICT in HAP.

Abstract
Phenytoin is a widely used antiseizure drug with well-documented side effects, including hypocalcemia, particularly in patients with concomitant vitamin D deficiency. Decreased serum calcium levels can induce seizures. In stabilized patients under long-term anticonvulsant treatment with phenytoin, loss of seizure control is rare but has been reported. This report illustrates a case of a 69-year-old woman under treatment with phenytoin for more than 10 years, who presented persistent hypocalcemia despite calcium correction, and seizures refractory to treatment with four combined antiepileptic drugs. She also presented with low vitamin D and elevated parathyroid hormone levels. Only when phenytoin administration was stopped it was possible to correct hypocalcemia and achieve seizure control. This case illustrates the need for regular monitoring and supplementation with calcium and vitamin D for patients under prolonged treatment with phenytoin. The proposed mechanism for phenytoin-induced hypocalcemia is reviewed. When installed, hypocalcemia can be resistant to supplementation until phenytoin is stopped, and in rare cases may lead to loss of seizure control.

Abstract
Obesity is associated with metabolic and physiological effects in the gut. In this study, we evaluated the anti-inflammatory effect of trypsin inhibitor isolated from tamarind seeds (TTI) in vitro (interaction with lipopolysaccharide (LPS) and inhibitory activity against human neutrophil elastase (HNE)), and using intestinal co-cultures of Caco-2:HT29-MTX cell lines inflamed with TNF-α (50 ng/mL) and a Wistar rat model of diet-induced obesity (n = 15). TTI was administered to animals by gavage (10 days), and the treated group (25 mg/kg/day) was compared to animals without treatment or treated with a nutritionally adequate diet. In the in vitro study, it showed inhibitory activity against HNE (93%). In co-cultures, there was no protection or recovery of the integrity of inflamed cell monolayers treated with TTI (1.0 mg/mL). In animals, TTI led to lower plasma concentrations of TNF-α and IL-6, total leukocytes, fasting glucose, and LDL-c (p < 0.05). The intestines demonstrated a lower degree of chronic enteritis, greater preservation of the submucosa, and greater intestinal wall thickness than the other groups (p = 0.042). Therefore, the better appearance of the intestine not reflected in the intestinal permeability added to the in vitro activity against HNE point to possibilities for new studies and applications related to this activity.

Abstract
BACKGROUND: TB notifications in Latin American prisons have more than doubled over the past two decades; however, treatment outcomes and their determinants among incarcerated individuals in this region are not well understood.METHODS: Newly diagnosed drug-susceptible TB cases reported to Brazil´s Information System for Notifiable Diseases (Sistema de Informação de Agravos de Notificação, SINAN) between January 2015 and December 2017 were included. Multivariate logistic regression was used to assess socio-economic and clinical factors associated with treatment success among incarcerated individuals.RESULTS: Incarcerated individuals (n = 17,776) had greater treatment success than non-incarcerated individuals (n = 160,728; 82.2% vs. 75.1%; P < 0.0001), including after adjusting for demographic and clinical risk factors (adjusted odds ratio aOR 1.27, 95% CI 1.19-1.34). These differences were partially mediated by increased use of directly observed therapy among incarcerated individuals (DOT) (61% vs. 47%; P < 0.001), which was associated with greater efficacy in the incarcerated population (aOR 2.56 vs. aOR 2.17; P < 0.001). DOT was associated with improved treatment success among incarcerated subpopulations at elevated risk of poor outcomes.CONCLUSION: TB treatment success among incarcerated individuals in Brazil is higher than non-incarcerated individuals, but both fall below WHO targets. Expanding the use of DOT and services for socially and medically vulnerable individuals may improve outcomes in carceral settings.

Abstract
Climate change is expected to have strong social-ecological implications, with global but especially regional and local challenges. To assess the climatic vulnerability of a given territory, it is necessary to evaluate its exposure to climate change and its adaptive capacity. This study describes the development of an Action Plan for Adapting to Climate Change in the Tâmega and Sousa Region, a mountainous inter-municipal community in the North of Portugal. The goals were to identify the main impacts of climate change on water resources, agriculture, forests, biodiversity, and socioeconomic sectors, as well as to develop a plan, merging local and scientific knowledge through a transdisciplinary lens. This study describes an approach that combines modelling methods, applied in the different sectors, and participatory methods, based on the analysis of the perceptions of local actors. Results indicate that the target region will experience a generalized increase in temperature and a decrease in precipitation, which will negatively impact all studied social-ecological dimensions. Overall, local business and institutional agents perceive the primary and tourism sectors as the most vulnerable in the region. The described framework demonstrates the engagement process between relevant scientific experts and local practitioners, as well as how it is critical to understand the impacts of climate change and to support the co-design of an adaptation plan, which in turn can guide political and economic decision-making towards effective implementation of the plan. In addition, the difficulties and challenges encountered during this process are discussed to support future plans and strategies for local adaptation.

Abstract
Oxidative stress, triggered by UV radiation, is one of the major causes of free radical-associated disorders, such as skin cancer. The application of natural compounds (NCs) with antioxidant effects can attenuate free radicals’ accumulation and, therefore, provide a strategy for skin care and cancer prevention. In this work, three natural compounds, naringenin, nordihydroguaiaretic acid (NDGA), and kaempferol, were encapsulated into nanostructured lipid carriers (NLCs) aiming for the development of a formulation for cutaneous application with antioxidant properties. For the experiments, different formulation parameters were evaluated to optimize the NLCs that showed a diameter around 200 nm, which is an adequate particle size for incorporation in cosmetics. Transmission electron microscopy (TEM) analysis confirmed the NLCs’ typical spherical morphology. Encapsulation efficiency (EE) and loading capacity (LC) values revealed an effective production process, with EEs over 90% and LCs near the maximum value. The developed NLCs revealed a prolonged in vitro release of the natural compounds. The NLCs were stable under storage conditions, maintaining their psychochemical characteristics for 30 days. Additionally, they did not show any physical instability in accelerated stability studies, which also suggests long-term stability. Finally, the NCs antioxidant activity was evaluated. Interestingly, the NDGA and kaempferol mixture provided an antioxidant synergic effect. The NLC formulations’ cytotoxicity was tested in vitro in immortalized human keratinocytes (HaCaT). In addition, putative antioxidant effects of the developed NLC formulations against tert-butyl hydroperoxide (t-BHP)-induced oxidative stress were studied, and the NDGA-loaded NLC was revealed to be the one with the most protective effect. Therefore, we concluded that the naringenin, NDGA, and kaempferol incorporation into NLCs constitutes a promising strategy to increase their bioavailability and delivery to the skin.

Abstract
Background
Cardiovascular diseases (CVD) are among the most prevalent illnesses worldwide, causing substantial mortality, morbidity and hospitalization. Understanding the correlation of thyroid function and glycemic metabolism and inflammation to body composition and cardiorespiratory and muscular function is imperative. This manuscript's main goal is to evaluate the association of thyroid function and glycemic metabolism to body mass composition and cardiovascular fitness (CRF) and muscular function in a group of coronary artery disease (CAD) patients.
Methods
To examine cross-sectional associations of thyroid function, glycemia, hemoglobin A1c (HgA1c) and C-reactive protein (CRP) with CRF, muscular function and body mass composition. Forty-five stable CAD patients were enrolled (aged 54.9 ± 10.0 years). Participants were assessed for body composition (DXA®), muscle strength (Biodex®), cardiorespiratory fitness (6-minute walking test) and blood biomarkers, including [CRP, Tyrode Hormones higher free thyroxine (FT4), lower total triiodothyronine (FT3) and metabolic parameters]. The Pearson correlation and t-test statistical measures were used for associations between thyroid function, glycemia, insulin, HgA1c and CRF/muscle strength, body composition.
Results
We found significant inter-correlations between body fat and FT4 (P < 0.01), HgA1c (P = 0.01), insulin (P = 0.01) and blood glucose (P = 0.05); lean mass and FT3 (P = 0.001); and a negative inter-correlation between C-reactive protein and knee extensor and flexor isokinetic peak torques (P < 0.01), and cardiorespiratory fitness (P < 0.05).
Conclusions
Our findings showed that THs function and body mass fat, HgA1c, blood glucose, insulin and CRP were associated with the CRF, muscle strength or body composition. These results highlight the importance of endocrine and metabolic mechanisms concerning CRF and muscle strength in a group of patients with CAD.

Abstract
The bone is a complex and dynamic structure subjected to constant stress and remodeling. Due to the worldwide incidence of bone disorders, tissue scaffolds and engineered bone tissues have emerged as solutions for bone grafting, which require sophisticated scaffolding architectures while keeping high mechanical performance. However, the conjugation of a bone-like scaffold architecture with efficient mechanical properties is still a critical challenge for biomedical applications. In this sense, the present study focused on the modulating the architecture of silk fibroin (SF) scaffolds crosslinked with horseradish peroxidase and mixed with zinc (Zn) and strontium (Sr)-doped β-tricalcium phosphate (ZnSr.TCP) to mimic bone structures. The ZnSr.TCP-SF hydrogels were tuned by programmable ice-templating parameters, and further freeze-dried, in order to obtain 3D scaffolds with controlled pore orientation. The results showed interconnected channels in the ZnSr.TCP-SF scaffolds that mimic the porous network of the native subchondral bone matrix. The architecture of the scaffolds was characterized by microCT, showing tunable pore size according to freezing temperatures (-196 °C: ∼80.2 ± 20.5 µm; -80 °C: ∼73.1 ± 20.5 µm; -20 °C: ∼104.7 ± 33.7 µm). The swelling ratio, weight loss, and rheological properties were also assessed, revealing efficient scaffold integrity and morphology after aqueous immersion. Thus, the ZnSr.TCP-SF scaffolds made of aligned porous structure were developed as affordable candidates for future applications in clinical osteoregeneration and in vitro bone tissue modelling.

Abstract
Inflammatory bowel diseases (IBD) with chronic infiltration of immune cells in the gastrointestinal tract are common and largely incurable. The therapeutic targeting of IBD has been hampered by the complex causality of the disease, with environmental insults like cholesterol-enriched Western diets playing a critical role. To address this drug development challenge, we report an easy-to-handle dietary cholesterol-based in vivo assay that allows the screening of immune-modulatory therapeutics in transgenic zebrafish models. An improvement in the feeding strategy with high cholesterol diet (HCD) selectively induces a robust and consistent infiltration of myeloid cells in larvae intestines that is highly suitable for compound discovery efforts. Using transgenics with fluorescent reporter expression in neutrophils, we take advantage of the unique zebrafish larvae clarity to monitor an acute inflammatory response in a whole organism context with a fully functional innate immune system. The use of semi-automated image acquisition and processing combined with quantitative image analysis allows categorizing anti- or pro-inflammatory compounds based on a leukocytic inflammation index. Our HCD gut inflammation (HCD-GI) assay is simple, cost- and time-effective as well as highly physiological which makes it unique when compared to chemical-based zebrafish models of IBD. Besides, diet is a highly controlled, selective and targeted trigger of intestinal inflammation that avoids extra-intestinal outcomes and reduces the chances of chemical-induced toxicity during screenings. We show the validity of this assay for a screening platform by testing two dietary phenolic acids, namely gallic acid (GA; 3,4,5-trihydroxybenzoic acid) and ferulic acid (FA; 4-hydroxy-3-methoxycinnamic acid), with well described anti-inflammatory actions in animal models of IBD. Analysis of common IBD therapeutics (Prednisolone and Mesalamine) proved the fidelity of our IBD-like intestinal inflammation model. In conclusion, the HCD-GI assay can facilitate and accelerate drug discovery efforts on IBD, by identification of novel lead molecules with immune modulatory action on intestinal neutrophilic inflammation. This will serve as a jumping-off point for more profound analyses of drug mechanisms and pathways involved in early IBD immune responses.

Abstract
The food industry has increased its interest in using "consumer-friendly" and natural ingredients to produce food products. In the case of emulsifiers, one of the possibilities is to use biopolymers with emulsification capacity, such as octenyl succinic anhydride modified starch, which can be used in combination with other polysaccharides, such as chitosan and carboxymethylcellulose, in order to improve the capacity to protect bioactive compounds. In this work, multilayer nano-emulsion systems loaded with oregano essential oil were produced by high energy methods and characterized. The process optimization was carried out based on the evaluation of particle size, polydispersity index, and zeta potential. Optimal conditions were achieved for one-layer nano-emulsions resulting in particle size and zeta potential of 180 nm and -42 mV, two layers (after chitosan addition) at 226 nm and 35 mV, and three layers (after carboxymethylcellulose addition) of 265 nm and -1 mV, respectively. The encapsulation efficiency of oregano essential oil within nano-emulsions was 97.1%. Stability was evaluated up to 21 days at 4 and 20 °C. The three layers nano-emulsion demonstrated to be an efficient delivery system of oregano essential oil, making 40% of the initial oregano essential oil available versus 13% obtained for oregano essential oil in oil, after exposure to simulated digestive conditions.

Abstract
Obesity is a chronic disease resulting from an imbalance between energy intake and expenditure. The growing relevance of this metabolic disease lies in its association with other comorbidities. Obesity is a multifaceted disease where intestinal hormones such as cholecystokinin (CCK), glucagon-like peptide 1 (GLP-1), and peptide YY (PYY), produced by enteroendocrine cells (EECs), have a pivotal role as signaling systems. Receptors for these hormones have been identified in the gut and different brain regions, highlighting the interconnection between gut and brain in satiation mechanisms. The intestinal microbiota (IM), directly interacting with EECs, can be modulated by the diet by providing specific nutrients that induce environmental changes in the gut ecosystem. Therefore, macronutrients may trigger the microbiota-gut-brain axis (MGBA) through mechanisms including specific nutrient-sensing receptors in EECs, inducing the secretion of specific hormones that lead to decreased appetite or increased energy expenditure. Designing drugs/functional foods based in bioactive compounds exploiting these nutrient-sensing mechanisms may offer an alternative treatment for obesity and/or associated metabolic diseases. Organ-on-a-chip technology represents a suitable approach to model multi-organ communication that can provide a robust platform for studying the potential of these compounds as modulators of the MGBA.

Abstract
Maturity-onset diabetes of the young (MODY) is a genetically and clinically heterogeneous group of diseases characterized by autosomal dominant monogenic non-ketogenic diabetes mellitus, usually with early-onset, with a prevalence of 1-5% of all diabetes cases. A 72-year-old female was admitted with intestinal occlusion, anorexia, vomiting, and weight loss for four months. Medical history of type 2 diabetes mellitus, chronic pancreatitis with abnormal pancreatic development, and acute obstructive jaundice due to a mass in the head of the pancreas with duodenum extension four months before. Assuming surgically unresectable pancreatic neoplasm, digestive bypass surgery was performed. The pathologic examination of surgical specimens was negative for neoplasm. Abdominal imaging showed the pancreatic mass, proximal bowel distension and ascites, which was negative for neoplastic cells. A percutaneous biopsy of the mass revealed adenocarcinoma. Palliative chemotherapy was started. Next-generation sequencing revealed the variant c.-8G>T in the 5’ untranslated region (UTR) region of the adenosine triphosphate (ATP) binding cassette subfamily C member 8 (ABCC8) gene in heterozygosity, associated with the MODY 12 subtype. We report a possible case of MODY 12 diabetes with a phenotype not previously described: a non-neoplastic pancreatic mass that appears in a previously abnormally developed pancreas, with evolution to neoplasm along with the late development of diabetes mellitus. Although this ABCC8 gene mutation could be incidental, there could be a relationship between this mutation, pancreatic malformation, chronic pancreatitis and pancreatic neoplasm. Investigation of new phenotypes is critical, including the potential role of the ABCC8 gene in oncogenesis.

Abstract
Congenital lobar emphysema (CLE) is a rare developmental abnormality of the lower respiratory tract. This disease is caused by cartilage or connective tissue defects, leading to overdistention of a pulmonary lobe. CLE is mainly diagnosed in early childhood, though it might be rarely found in young adults. Due to its rarity, it can be misdiagnosed with other conditions. Here we report a case of a previously healthy young female complaining of dyspnea and thoracic pain after a commercial flight. Physical and radiological examinations were consistent with the diagnosis of CLE.

Abstract
Simple Summary The tomato fruitworm, Helicoverpa armigera, is a key pest of several crops. It can cause particularly extensive damage in crops of processing tomatoes. Risk assessment can be a tedious and costly task if sampling protocols require a large number of plants. Sequential sampling allows sampling of a reduced number of plants when population densities are much lower or much higher than the economic or control threshold. Additionally, for crop protection purposes, sampling for classification (to assess if population density is lower or higher than the economic threshold) is adequate and requires much less effort. We studied the preferred location of eggs found on plants and then described the spatial pattern of oviposition in processing tomatoes using Taylor’s power law. Eggs were found more frequently in the exposed canopy in the upper and middle-upper strata, directly below open flower clusters, with an aggregated spatial pattern. A sequential plan was developed for 20 and 80 plants, as minimum and maximum sample sizes, respectively. This reduces sampling efforts and costs when compared to the fixed number sampling plan, and provides acceptable precision in decision-making for this pest in a processing tomato crop. Abstract Helicoverpa armigera is one of the key pests affecting processing tomatoes and many other crops. A three-year study was conducted to describe the oviposition preferences of this species on determinate tomato plants (mainly the stratum, leaf, leaflet, and leaf side) and the spatial pattern of the eggs in the field, to form a sequential sampling plan. Eggs were found mainly in the exposed canopy, on leaves a (upper stratum) and b (upper-middle stratum) and significantly fewer eggs on leaf c (middle-lower stratum) below flower clusters. This vertical pattern in the plant was found in all phenological growth stages. The spatial pattern was found to be aggregated, with a trend towards a random pattern at lower densities. A sequential sampling plan was developed, based on Iwao’s method with the parameters of Taylor’s power law, with minimum and maximum sample size of 20 and 80 sample units (plants), respectively (two leaves/plant). For its validation, operating characteristic (OC) and average sample number (ASN) curves were calculated by means of simulation with independent data sets. The β-error was higher than desirable in the vicinity of the economic threshold, but this sampling plan is regarded as an improvement both in effort and precision, compared with the fixed sample plan, and further improvements are discussed.

Abstract
Over the last decades, antifouling coatings containing biocidal compounds as active ingredients were used to prevent biofouling, and eco-friendly alternatives are needed. Previous research from our group showed that polymethoxylated chalcones and glycosylated flavones obtained by synthesis displayed antifouling activity with low toxicity. In this work, ten new polymethoxylated flavones and chalcones were synthesized for the first time, including eight with a triazole moiety. Eight known flavones and chalcones were also synthesized and tested in order to construct a quantitative structure-activity relationship (QSAR) model for these compounds. Three different antifouling profiles were found: three compounds (1b, 11a and 11b) exhibited anti-settlement activity against a macrofouling species (Mytilus galloprovincialis), two compounds (6a and 6b) exhibited inhibitory activity against the biofilm-forming marine bacteria Roseobacter litoralis and one compound (7b) exhibited activity against both mussel larvae and microalgae Navicula sp. Hydrogen bonding acceptor ability of the molecule was the most significant descriptor contributing positively to the mussel larvae anti-settlement activity and, in fact, the triazolyl glycosylated chalcone 7b was the most potent compound against this species. The most promising compounds were not toxic to Artemia salina, highlighting the importance of pursuing the development of new synthetic antifouling agents as an ecofriendly and sustainable alternative for the marine industry.

Abstract
The current study developed and tested the indirect effect of the relational job characteristics (i.e., perceived prosocial impact and perceived social value) on the burnout syndrome through the autonomous motivation. The cross-sectional survey data analysis of 1,538 Portuguese contact center workers was analyzed using the software package Mplus to conduct structural equation models. Autonomous motivation partially explains the negative relation between the relational job characteristics and burnout. However, the direct relationship between perceived prosocial impact and burnout was not significant. To promote awareness about the perceived value and impact of work and to invest in the interactions between workers and customers are the major practical implications of this study.

Abstract
β-carotene loaded bio-based nanoparticles (NPs) were produced by the solvent-displacement method using two polymers: zein and ethylcellulose. The production of NPs was optimised through an experimental design and characterised in terms of average size and polydispersity index. The processing conditions that allowed to obtain NPs (<100 nm) were used for β-carotene encapsulation. Then β-carotene loaded NPs were characterised in terms of zeta potential and encapsulation efficiency. Transmission electron microscopy, Fourier transform infrared spectroscopy and X-ray diffraction analysis were performed for further morphological and chemical characterisation. In the end, a static in vitro digestion following the INFOGEST protocol was performed and the bioaccessibility of β-carotene encapsulated in both NPs was determined. Results show that the best conditions for a size-controlled production with a narrow size distribution are lower polymer concentrations and higher antisolvent concentrations. The encapsulation of β-carotene in ethylcellulose NPs resulted in nanoparticles with a mean average size of 60 ± 9 nm and encapsulation efficiency of 74 ± 2%. β-carotene loaded zein-based NPs resulted in a mean size of 83 ± 8 nm and encapsulation efficiency of 93 ± 4%. Results obtained from the in vitro digestion showed that β-carotene bioaccessibility when encapsulated in zein NPs is 37 ± 1%, which is higher than the value of 8.3 ± 0.1% obtained for the ethylcellulose NPs.

Abstract
Grape pomace (GP) is a major by-product from the wine industry, known for its bioactive compounds and their impact upon gastrointestinal (GI) health. However, bioaccessibility is often poor due to their degradation during digestion. This work aimed to encapsulate bioactive GP extract (GPE) into chitosan (CS) and alginate (Alg) nanoparticles (NPs) to mitigate degradation in the GI tract. Alg and CS NPs were optimized using a rotatable central composite design and NPs were characterized for their size, polydispersity, zeta potential and total phenolics (TP) association efficiency. The best formulations showed sizes ranging 523-853 nm, polydispersity indexes of 0.11-0.36, zeta potential of -15.0-14.9 mV and TP association efficiencies of 68 and 65%. FTIR confirmed that there was no formation of new chemical groups after association of the polymers with GPE. Both formulations improved the bioaccessibility of different phenolics following in vitro GI digestion, leading to increased antioxidant and antimicrobial activities. Moreover, the permeability of bioactive compounds through a Caco-2/HT29-MTX co-culture was reduced, suggesting a higher residence time in the intestine. Cy5.5 was used for tracking the CS NPs, which did not affect the metabolic activity of Caco-2 and HT29-MTX cells. Confocal microscopy images confirmed the adsorption of NPs to the cellular layer and suggested a reduction of the tight junction protein occludin when cells were incubated with Cy5.5-CS in solution. This study suggests that encapsulation of GPE can offer protection against along the GI tract and improve its biological activity with significant impact for oral delivery applications, including functional foods.

Abstract
Lignin particles (LPs) have gained prominence due to their biodegradability and bioactive properties. LP production at nano and micro scale produced from organosolv lignin and the understanding of size's effect on their properties is unexplored. This work aimed to produce and characterize lignin nanoparticles and microparticles using a green synthesis process, based on ethanol-solubilized lignin and water. Spherical shape LPs, with a mean size of 75 nm and 215 nm and with a low polydispersity were produced, as confirmed by transmission electron microscopy and dynamic light scattering. LPs thermal stability improved over raw lignin, and the chemical structure of lignin was not affected by the production method. The antimicrobial tests proved that LPs presented a bacteriostatic effect on Escherichiacoli and Salmonella enterica. Regarding the antioxidant potential, LPs had a good antioxidant activity that increased with the reaction time and LPs concentration. LPs also presented an antioxidant effect against intracellular ROS, reducing the intracellular ROS levels significantly. Furthermore, the LPs showed a low cytotoxic effect in Caco-2 cell line. These results showed that LPs at different scales (nano and micro) present biological properties and are safe to be used in different high value industrial sectors, such as biomedical, pharmaceutical and food.

Abstract
Abstract
Background
Understanding salt-related knowledge, attitudes and behaviors can help the design of effective health interventions. Therefore, our objective was to describe knowledge and behaviors related to salt intake according to urinary sodium excretion and blood pressure in University workers.
Methods
We performed our study in a subsample of the participants of the iMC Salt project (n = 60 subjects, 60.5% women, mean age 48±9.5 years). Sodium excretion were measured by one 24-h urinary collection, validated by creatinine excretion and participants were grouped according to the WHO sodium recommendations (<2.0 g/day; high, ≥2.0 g/day). Subjects were classified as hypertensive if the systolic blood pressure was ≥130 mmHg and/or diastolic blood pressure was ≥80mmHg. Knowledge and behaviors regarding salt intake were assessed by the WHO Stepwise Approach to Chronic Disease Risk Factor Surveillance.
Results
About 74.6% of the participants reported that reducing salt in their diet was very important and 93.2% think that salt is harmful to health. However, 76.3% always add salt during cooking, 42.4% said that they always or often consume processed foods high in salt, 79.7% reported that they don't look at the salt on food labels, 50.8% don't buy low salt alternatives and 30.5% don't use spices as one substitute for salt when cooking. Hypertensive subjects had a higher mean sodium excretion (3710±1508mg/day vs 2478±871mg/day, p = 0.002) and reported a significant higher frequency of consumption of processed foods high in salt (53.1% vs 29.6%, p = 0.024). No significant differences were found with the other variables.
Conclusions
Most university workers were aware that high salt intake can cause health problems, but they reported low adherence to behaviors to control their salt intake. Hypertensive subjects recognized that frequently consume processed foods high in salt, so reduce salt content on those products could have important impact on their daily salt consumption.
Key messages
This study provides evidence on knowledge and behaviors regarding salt intake to guide salt reduction policies. Hypertensive participants reported a higher frequency of eating processed foods rich in salt.

Abstract
Abstract
Background
The National Policy for Hearing Health Care in Brazil proposes that all newborns in the country undergo hearing screening in the first month of life.The Universal Neonatal Hearing Screening Program being extremely important for the early intervention of deafness. However, many parents/guardians do not return to the auditory retest, interrupting the neonatal protocol and making early auditory diagnosis impossible. Objective:To analyze the reasons for the non-attendance to retest of the Hearing Screening of a hospital in Curitiba.
Methods
This study was carried out in a Public Hospital, with live births from August 2017-May 2018. All the born were considered for the variables gender, risk for hearing loss, age at birth, results of Hearing Screening. Failed babies were analyzed, including the active search of those who did not attend the retest, through contact with parents/guardians to collect the reasons for faults.
Results
2,531 infants were born, male had a prevalence of 1,275 (50.38%), term born 1,734(68.51%) and ICU stay as the most common risk indicator - 118(79.73%). 2,261(89.33%) infant passed on both ear; among those who failed only 94(40.0%) attended the retest. An active search was performed by phone, and 78(55.31%) could not establish contact, totaling 47(54.02%) mothers contacting. These motherś age was 19 to 24 years, 56.92% of whom had high school. The majority of those in charge are aware of the result of the test of the ear of their son (82.97%), was directed to test again (87.23%), were not able to answer the reason for not attending (27.65%) or had forgotten about this commitment (19.14%).
Conclusions
The data analyzed showed the lack of information that parents / guardians of the newborns give to the Hearing Screening, which compromises the integrality of health actions in newborns, making it necessary to seek other ways to ensure family adherence to the Program.
Key messages
Babies at risk of deafness need constant monitoring. Without parental participation, there is no success in health programs.

Abstract
Abstract
Background
Vascular function and blood pressure regulation may be impaired by acute hypohydration but data on the association between hypertension and hydration status is scarce. The objectives of this study were to evaluate the hydration status in a sample of university workers and to assess the association between hypertension and hydration status.
Methods
A cross-sectional evaluation of a sample of 60 university workers (32 women) was conducted in 2019/2020 in Portugal. A 24-hour urine sample was collected; urinary volume, creatinine and osmolality were quantified. Free water reserve (FWR) was used to assess hydration status and subjects were classified as hypohydrated (FWR<0) or euhydrated (FWR > =0). Arterial blood pressure was evaluated [average of 2 blood pressure (BP) measurements] by researchers using standard methodology and participants with systolic and diastolic blood pressure ≥130 mm Hg and/or ≥80 mm Hg, respectively, were classified as hypertensive. A binary logistic regression model was used to estimate the association between hypohydration and hypertension, adjusting for sex, age and use of anti-hypertensive drugs. Odds Ratios (OR) and respective 95% Confidence Intervals (95%CI) were calculated.
Results
Hypertension was observed in 40.6% of women and 67.9% of men whereas hypohydration affected 31.3% of women and 32.1% of men. After adjusting for confounders, hypertension was associated with a 7-fold increased risk of hypohydration (OR = 7.56; 95% CI: 1.81-31.59).
Conclusions
These results stress the positive association between hypohydration and hypertension and highlight the need for implementing strategies for the promotion of water intake, particularly in the hypertensive patients.
This project was granted by Fundação para a Ciência e Tecnologia - Grant POCI-01-0145-FEDER-029269.
Key messages
Hypohydration affect nearly one third of this sample of university workers. Hypertension was associated with a 7-fold increased risk of hypohydration.

Abstract
Abstract
Issue
In Portugal, most of the salt consumed comes from the salt added during preparation/cooking. Therefore, it is urgent to introduce mechanisms to allow the quantification of the salt in foods, and the salt added during culinary.
Description of the Problem
To tackle salt reduction, we considered: having a portable and user-friendly instrument that measure salt content of foods; and controlling the amount of salt added to foods during culinary, assessing its impact on health. The first project was SALT QUANTI (co-funded by NORTE 2020), promoted by a consortium between EVOLEO Technologies and the University of Porto (finished in September 2018, duration 18 months); its major deliverable was to obtain a prototype of a portable device and the analytical procedure that enabled the analysis of salt content in foods/meals produced in catering kitchens, in less than 5 minutes. The second project was iMC SALT (supported by FCT, Grant POCI-01-0145-FEDER-029269), started in July 2018 (duration 36 months), aiming to develop prototypes for controlling the amount of salt added to foods during culinary, at home and catering, according international recommendations; one clinical intervention to assess the impact on health of the prototype at home is underway.
Results
The SALT QUANTI and iMC SALT prototypes showed good results in validation tests. The preliminary results of the health impact of the iMC SALT prototype will be presented at the conference.
Lessons
The implementation of innovative equipments to help consumers and catering industry to monitor or control the addition of salt during preparation of food or cooking are expected to be available soon and to be useful to consumers and catering industry to reduce salt intake.
Key messages
Innovative equipments may contribute to estimate salt in foods, and to reduce salt added during culinary. The implementation of an equipment to control culinary salt could be one valid approach to reduce salt consumption with impact on health.

Abstract
Abstract
Background
Worldwide, workers' health is still a Public Health concern, given the high number of hazardous occupational activities, as well as workers affected by work-related diseases. Among these diseases, occupational Noise-Induced Hearing Loss-NIHL is considered the second commonest occupational disease, and in Brazil, its reporting is compulsory. However, occupational diseases are usually underreported, hindering the knowledge of their actual magnitude, and the elaboration of prevention-oriented public policies.
Objective
To analyze the perception and knowledge of Primary Health Care professionals in Curitiba-Parana State, Brazil, on the compulsory NIHL reporting.
Methods
quantitative and qualitative approach conducted in three steps: analysis of a series of NIHL case histories reported in the official database between 2007 and 2018; application of a questionnaire to Primary Health Care Network professionals; collective interview with Primary Health Care Network nurses, speech therapists and doctors.
Results
NIHL reporting evidenced 82 cases, 67 (81.7%) among males, age ranging 50-64 years, 10 (12.2%) had complete high school level, 27 (32.9%) were formally employed, and 12 (14.6%) worked in the processing industry. Regarding the result of the applied questionnaire among the Primary Health Care professionals, 48 (68.7%) stated that they were prepared to identify workers' health problems, to 33 (68.7%) professionals, guidance to reassure users' comprehensive care is more important than the compulsory reporting, 21 (43.7%) claimed that they were qualified to identify NIHL cases, and 25 (52.1%) did not report the cases. Difficulties in reporting NIHL cases are: not understanding their flow, being afraid of the legal implications, which may generate difficulties in requesting audiometric testing, not having the management support, etc.
Conclusions
Most health care professionals are knowledgeable on NIHL, but they do not report the suspected cases due to lack of guidance.
Key messages
Primary care health professionals does not consider occupational health as part of the service to be provided. Primary care services are not prepared to establish the relationship between the injury and the job.

Abstract
BACKGROUND Intravenous drug users (IDUs) with hepatitis C virus (HCV)/human immunodeficiency virus (HIV)-coinfection are recognised as a high-risk, vulnerable group. METHODS Between February 2015 and April 2018, a single-centre, non-interventional cohort study was conducted in an outpatient setting, to evaluate the sustained virologic response (SVR12) and assess treatment uptake models. The study included 385 former or recent IDUs divided into two groups: A-without use of opioid substitution treatment (OST) and B-patients taking opioid substitution; patients in group B received OST and self-administered therapy (B1) or OST and therapy under DOT (B2). Patients were characterised by demographic and clinical features and compared for treatment response. Correlations between SVR12 and independent variables were determined by logistic regression. RESULTS Patients were mostly males (88.3%) with a mean age of 46 ± 5 years and HCV genotype 1a (63.7%). Approximately 28% were treatment-experienced and 84.9% received sofosbuvir/ledipasvir. The mean CD4+T count was 649 cells/mm3, and most individuals were on antiretroviral therapy with undetectable viral loads (97.4%). SVR12 was achieved in 94.8%, and only eight patients relapsed. No significant differences were found in treatment effect between individuals taking opioid substitutes under different treatment models. Correlations were found between HCV viral response and both HIV suppression and albumin levels. CONCLUSIONS IDU with HCV/HIV coinfection, including individuals on self-administration of HCV therapy and opioid substitution treatments or in DOT programmes, are no longer considered a difficult-to-treat group, as they achieve high rates of SVR12.

Abstract
Background Oral administration remains the most common mode of drug delivery. However, orally administered bioactive compounds must first survive digestion and then be absorbed at the intestine in order to reach other tissues or organs. The efficiency of both processes can be improved by encapsulation or conjugation with polymeric nanoparticles. Here we report the synthesis of amphiphilic hyaluronic acid (HyA) nanogels as nanocarriers for drug delivery. Methods HyA nanogels were prepared by self-assembly from amphiphilic HyA conjugates produced by grafting hydrophobic alkyl chains to the HyA backbone. The dye Cy5.5 was covalently bonded and used for tracking. The nanogels were characterised according to their structure, size and zeta potential, as well as biocompatibility towards an intestinal epithelial cell line. The uptake and intestinal permeability of the nanogels were assessed using in vitro models, which physiological relevance was verified regarding the morphology of the epithelium, the production of mucus, the expression of occludin and the transepithelial electrical resistance. Results The covalent binding of Cy5.5 did not affect significantly the size and surface charge of the nanogels at 125.1 ± 3.2 nm and -57.6 ± 6.2 mV respectively after labelling. Studies of biocompatibility showed that the nanogels were non-toxic to Caco-2 cells up to the concentration of 0.1 mg∙mL-1. The presence of mucus affected the nanogel uptake and highlighted the importance of considering mucus-producing cells in in vitro intestinal models. The uptake or adsorption to a Caco-2/HT29-MTX co-culture (8.1%) was higher than with single Caco-2 cell cultures (4.3%). Interestingly, both models led to minute (<0.5%) permeation of the nanogels across the intestinal barrier. Conclusion The HyA nanogels demonstrated to be mucoadhesive and effectively uptaken by intestinal cells. Both are determinant features for sustained release, but if systemic delivery is envisaged further modification with targeting moieties could be important to improve the nanogel permeability.

Abstract
In vivo studies show the benefits of the trypsin inhibitor isolated from tamarind (Tamarindusindica L.) (TTI) seeds in satiety and obesity. In the present study, TTI nanoencapsulation (ECW) was performed to potentialize the effect of TTI and allow a controlled release in the stomach. The impact on glycemia, insulin, and lipid profile was evaluated in Wistar rats overfed with a high glycemic index diet (HGLI). Characterization of the nanoparticles and in vitro stability in simulated gastrointestinal conditions, monitored by antitrypsin activity and HPLC, was performed. ECW and empty nanoparticles (CW) were administered by gavage, using 12.5 and 10.0 mg/kg, respectively. Both nanoformulations presented a spherical shape and smooth surface, with an average diameter of 117.4 nm (24.1) for ECW and 123.9 nm (11.3) for CW. ECW maintained the antitrypsin activity (95.5%) in the gastric phase, while TTI was completely hydrolyzed. In Wistar rats, the nanoformulations significantly reduced glycemia and HOMA IR, and ECW increased HDL-c compared to CW (p < 0.05).Pancreas histopathology of animals treated with ECW suggested an onset of tissue repair. Thenanoencapsulation provided TTI protection, gradual release in the desired condition, and improvement of biochemical parameters related to carbohydrate metabolism disorders,without compromising insulinemia.

Abstract
The management of vineyards depends on the use of plant protection agents. Regardless of the numerous environmental impacts that these pesticides generate during their production, their dosage as pest control agents in vineyards causes an important toxic effect that must be monitored. Copper-based inorganic pesticides are the most widely used agents to control fungal diseases in humid wine-growing regions. It is, however, significant that the environmental analysis of their use through the Life Cycle Assessment (LCA) methodology does not provide detailed information on the potential toxicity of this type of pesticides. Hence, most studies report average values for copper characterization factors (CFs), excluding local soil characteristics. The objective of the study was the spatial characterization of the ecotoxicity factors of copper soil emissions as a function of the chemical characteristics of vineyard soils located in Portugal and Galicia (NW Spain). A multiple linear regression model was applied to calculate the comparative toxic potential. Subsequently, CFs for copper were calculated based on spatial differentiation considering the variable properties of the soil within each wine appellation. The CFs obtained for the area evaluated ranged from 141 to 5937 PAF·m3·day/kgCu emitted, for fibric histosols (HSf) and dystic cambisols (CMd), respectively. Moreover, the average values obtained for Galician and Portuguese soils were 1145 and 2274 PAF·m3·day/kgCu emitted, respectively. The results obtained illustrate the high variability of CF values as a function of the chemical characteristics of each type of soil. For example, Cu soil mobility was linked to organic carbon content and pH. Finally, to validate the representativeness of the calculated CFs, these were applied to the results of 12 literature life cycle inventories of grape production in the area evaluated, revealing that impact scores associated with Cu emissions can considerably vary when spatially-differentiated CFs are implemented.

Abstract
BACKGROUND There are different neck proprioceptive tests that are believed to be targeting different sources of proprioceptive information. OBJECTIVE To assess the reliability, measurement error, discriminative validity and convergent validity of four proprioceptive tests (head repositioning to neutral - HRNT, torsion test - TT, head repositioning to 30° rotation - HR30T and figure of eight relocation test - F8T) in individuals with chronic idiopathic neck pain and asymptomatic individuals. A secondary aim was to assess the divergent validity of these tests by correlating them against measures of disability, pain catastrophizing and fear of movement. DESIGN - Reliability and validity study. METHODS - 66 participants (33 with chronic neck pain and 33 asymptomatic) were assessed using four proprioceptive tests, pain catastrophizing scale, neck disability index, tampa scale of kinesiophobia and visual analogue scale. RESULTS Proprioceptive tests showed moderate to good reliability (ICC: 0.55 to 0.85), but high measurement error. All tests but the HR30T were significantly different between participants with and without neck pain (p < 0.05). Only the HRNT showed an area under the curve above 0.5 (AUC95% CI = 0.51; 0.78, p ≤ 0.042). Between test correlations ranged between 0.35 and 0.61 and correlations between proprioceptive tests and catastrophizing, fear of movement and disability were, in general, lower than 0.3. CONCLUSION The four proprioceptive tests showed reliability and measurement errors good enough for group comparisons but of limited utility for individual comparisons. They seem to measure related but dissimilar constructs and the HRNT seemed better at discriminating individuals with and without NP and easier to perform in clinical practice.
