The adoption of a vegetarian diet increased over the years. In Portugal, is estimated that 1.2% of the population follows this food pattern. A cross-sectional study was carried out, including a final sample of 74 nutrition professionals to assess their position concerning the vegetarian diet (VD) according to their year of graduation (YG). The results analyses demonstrated that 23 nutrition professionals graduated between 1980 and 2009; and 51 between 2010 and 2019. There were statistically significant differences regarding the possibility of keeping a VD throughout life, since 81.1% of the participants consider it possible, most of them belonging to the group who graduated after 2009. As for supplements, 13% of the nutrition professionals who graduated until 2009 believe it possible to adhere to a VD without resorting to supplements, however, the percentage increases significantly to 39.2% in nutrition professionals trained after 2009. The percentage of nutrition professionals that approved the adherence of athletes to VD increased statistically in recent years, however, most believe this adherence is only possible with the use of supplements. Adherence to VD has increased over the past few years, however, the opinion of nutrition professionals is not unanimous regarding its safety, effectiveness in weight loss, and use of supplementation.

Algorithms, queries, and knowledge-based systems are among approaches to screen electronic patient records stored in databases and support pharmacist medication reviews. The aim of this study was to perform a type 1 medication review and identify clusters that enable the definition of an algorithm to tailor pharmacy professional interv A retrospective observational study was conducted on a convenience sample of pharmacy records. Records were included if patients had a medication dispensing history between June 2017 - July 2018 and used two or more chronic medications. Statistical analysis used a two-step cluster to identify common characteristics among fifty-five sets of patient records which underwent Type 1 medication review. The median number of drugs used per patient was five [IQR: 3.0 – 7.0]. 18.2% of patients had inappropriate drugs, and 30.9% had moderate or major interaction potential. Four clusters were identified based on the variables of interactions, number of drugs used, contraindications, Beers criteria and measurable biomarkers, allowing to envision possible pharmaceutical interventions, as well as the priority in providing that intervention. The identification of patient clusters via medication review of electronic records of pharmacy patients supports the design of criteria-based algorithms, likely to be automated.

Some challengers such as methylnicotinate (MN) have been used in human models to study the anti-inflammatory effect of topical formulations. However, MN skin responses are still poorly understood and widely varied. In the present study we aim to contribute to better characterise those responses. Eight healthy participants were selected. All procedures were approved by the institutional Ethics Committee. Two aqueous MN dilutions (0.5% and 1.0%) were left in contact for 1 minute in the anterior forearm skin. Following exposure, skin reactions were clinically and biometrically assessed at 30, 60 and 120 minutes and compared with baseline. Measurements involved the ICDRG clinical score scale and select analytical technologies - laser Doppler flowmetry, Polarised Spectroscopy, Transepidermal Water Loss Meter, and High Resolution Sonography. Results have shown that MN application evoked a maximal response at 30 minutes with an increase in the ICDRG score between 1-2. Significant changes in TEWL and microcirculation were observed, as was an increased dermal hypoecogenicity (edema), detected by HRS. These effects are compatible with a localised short-duration inflammation and reinforce the interest of MN to be used as a safe and controllable challenger in human models.

There is a great diversity of plants which are grown in the Atlantic Forest region of Brazil that produce small, colorful, edible fruit that are used in empiric mode to treat several diseases, such as diabetes, as fruits are a rich source of dietary phenolic antioxidants. In this study, we investigated the inhibitory activity of methanolic fruit extracts from the Myrtaceae family - Psidium cattleianum (araçá), Syzygium cumini (jambolão), Campomanesia xanthocarpa (guabiroba), Eugenia uniflora (pitanga) and Eugenia pyriformis (uvaia) - against α-amylase and intestinal α-glucosidase (maltose and sucrose). The antioxidant activities were evaluated using two different in vitro assays: the 2,2’-azinobis(3-ethylbenzthiazoline-6-sulphonate) (ABTS) test and the 2,2’-diphenyl-1-picrylhydrazyl (DPPH) test. The extracts of P. cattleianum, S. cumini, E. pyriformis inhibited α-amylase activity between 13% and 60% (p<0.05). The extracts of P. cattleianum also inhibited α-glucosidase activity with either maltose or sucrose as substrate between 15% and 61% (p<0.05). Additionally, these fruits are rich in phenolic compounds with antioxidant activities.

Diet is commonly accepted as a determinant of body composition, especially when related to specific lifestyles. Vegetarian-vegan diets, which involve a reduction or elimination of animal product consumption, are believed to be more “healthy,” facilitating weight control and reducing the incidence and clinical course of different diseases, in particular those related to overweight and obesity. Global reviews and metanalysis on these issues, however, are still insufficient. Our preliminary approach addresses the total body composition differences among vegetarians-vegans and omnivorous individuals. This cross-sectional study involved ten healthy women, five vegetarian-vegan, and five omnivores (mean 28.10 years old). Body composition was assessed using a dual-energy x-ray absorptiometry (DXA Lunar Prodigy Advance - General Electric Healthcare®). Other general and sociodemographic variables were also collected by trained dietitians. Our results have shown that the vegetarian-vegan group had a non-significantly lower volume of all types of body mass (total bone, fat, lean, tissue, and fat-free) evaluated. Additionally, the vegetarian-vegan group presented higher values of visceral adipose tissue and subcutaneous adipose tissue (286.20 and 11138.40 cm3, respectively, p > 0.05) compared to the omnivore group. These differences will be further confirmed in subsequent studies.
人们普遍认为饮食是身体组成的决定因素，尤其是与特定的生活方式有关时。素食-纯素饮食涉及减少或消除动物产品的消费，被认为更“健康”，有助于控制体重，减少各种疾病的发病率和临床病程，特别是那些与超重和肥胖有关的疾病。然而，关于这些问题的全球综述和元分析仍然不足。我们的初步方法解决了素食者-素食者和杂食性个体之间的总体组成差异。这项横断面研究涉及10名健康女性，5名素食者和5名杂食者(平均年龄28.10岁)。使用双能x线吸收仪(DXA Lunar Prodigy Advance - General Electric Healthcare®)评估体成分。其他一般和社会人口变量也由训练有素的营养师收集。我们的结果显示，素食-纯素食组在所有类型的体重(总骨骼、脂肪、瘦肉、组织和无脂肪)评估中都没有显著降低。此外，素食-素食组内脏脂肪组织和皮下脂肪组织的数值分别为286.20和11138.40 cm3, p > 0.05)高于杂食组。这些差异将在后续的研究中得到进一步证实。

Obtaining new cosmetic ingredients, mainly from sustainable sources, as novel excipients or even active compounds is noteworthy for the cosmetic industry to enhance new innovative dermocosmetics. Thus, it is essential to establish the safety of these new ingredients to avoid adverse events, mainly those associated with clastogenic effects from the chemical compounds used for collagen extraction. In this study, we evaluated solutions of chemical compounds used in the collagen extraction process from tilapia skin (Oreochromis niloticus). The cytotoxic and genotoxic effects of the solutions used in the collagen extraction process were 10.0, 1.0, 0.5, and 0.1% n-butanol. Solutions were evaluated by the Allium test and the comet assay in peripheral white blood cells. The residual water from the final skin wash in the pre-treatment phase and the 0.5% lyophilized collagen extract were also investigated. The absence of cytotoxic and genotoxic activity was demonstrated in the collagen extract, despite the fact that n-butanol showed DNA damage, both in the root cells of Allium cepa and in the white blood cells of human peripheral blood. Therefore, we note the necessity to carry out genotoxicity tests to guarantee the absence of contaminants in the collagen extract for cosmetic purposes

Body posture and movement seem to be responsible for multiple variations of microcirculation in the foot, although difficulties associated with measurement during movement have limited their characterization. This pilot study sought to explore a new non-invasive instrument based on polarized light spectroscopy – the TiVi system, under orthostatic and dynamic conditions. Five healthy participants (duly informed, 26.0 ± 6.5 years of age) of both genders were selected. The protocol involved sequential posture changes (orthostatic variation) and dynamic movements (squatting and unipodal flexion). Perfusion variations were evaluated in both feet by laser-Doppler flowmetry (LDF) and polarized spectroscopy (TiVi). Both systems revealed the same type of modification of these flow-related variables. The most pronounced changes were obtained with exercise, especially with squatting, which caused a marked increase in foot perfusion. Less dramatic but in the same direction, the increased perfusion with unipodal flexion was also observed in the contralateral limb. This study confirmed the interest in using the TiVi system in these domains, as well as the appropriateness of this experimental design to look deeper into the impact of lower limb movement on the functional dynamics of the foot.

A year for balance This was our first year of a new (risky) experience, assuming a totally online edition, new editorial procedures, organization, and layout. Happening in a year definitively marked by the extraordinary global crisis caused by this SARS COVID19 changing the definition of “normality” in all aspects of our life. Biomedical and Biopharmaceutical Research journal is no exception. The year of our full open access was simultaneously, the year of many other changes and impacts. Crisis always give space to opportunities, and we did got ours. BBR journal achieved to be more professional and available. Closer to the authors, to the reviewers and editors interacting in a regular way. Stronger in its processes and therefore more rigorous and transparent, in the right track for consolidation. This is no doubt, the most productive editorial year ever in the history of BBR. Our options were clearly accepted by our authors. We read these outcomes as a trust token that we deeply appreciate. Our success is their success. Therefore, we will continue to do more and better for this instrument of scientific culture specially conceived and reasoned in the common language of our Portuguese speaking communities. We stress our independent character, non-profit defined, exclusively based in the science and education, wholeheartedly dedicated to the growth of scientific culture. This is part of our foundation and our compromise for the future. This 2020 closure number includes two articles in the Nutrition and Food Sciences section, six articles in the Biomedical Sciences section and six others in the Biopharmaceutical Sciences section. Three other documents complete this number – the Proceedings Book of the 55th Annual Congress of the Brazilian Society of Physiology which included the 1st Portuguese-Brazilian Physiology Meeting organized by both countries’ (sister) Physiology Societies, the Proceedings Book from the 2020 CBIOS Science Sessions, and the Proceedings Book from the IV CBIOS Seminar 2020.

As a global epidemic, obesity is currently a significant public health challenge, especially in children. Childhood obesity is related to short term consequences, but also with an increased risk to develop many comorbidities in adult life, such as cardiovascular diseases, type 2 diabetes, strokes, and others. A cross-sectional study to assess the prevalence of normal weight, pre-obesity and obesity in school-aged children was designed. The final sample size analyzed included 81 participants (47 boys and 34 girls) aged between 6 and 14 years old. Pre-obesity and obesity were determined according to the BMI cut-off points adopted by the IOTF. Although no significant differences were found, the prevalence of pre-obesity and obesity for the total population studied was 16.00% and 6.20%, respectively, with 14.60%, and 4.30% for boys and 17.60% and 8.80% for girls. More girls were pre-obese and obese than boys except at ages 9 and 12. The same age that boys presented cardiometabolic risk associated with a WHtR>0.50. These results emphasize the importance of nutritional status assessment to develop appropriate actions to prevent childhood obesity.
