Desenvolvimento de produto: empadas equilibradas nutricionalmente

Mestrado em Engenharia Alimentar - Instituto Superior de AgronomiaThis dissertation explores the development of nutritional balanced “empadas and also its sensorial e microbiological properties. Cook 4 Day Lda passed the knowledge behind this type of product, and what were the objectives. With the bibliographic review was possible to identify various eating disorders within the portuguese population, being the cause of numerous diseases. With this info, it was clear that the new product should have in count this kind of problematics and others like celiac disease and cancer. It were developed two recipes with different types of dough, one with wheat flour and olive oil and another one without gluten, through the use of corn flour and olive oil too. The other four recipes were developed for the fillings of the “empadas”, two vegetarian’s recipes one for the dough without gluten and another for the dough with gluten, a filling of red fruits and a filling of sardine. The process of creating the recipes mentioned above implied the creation of a nutritional simulator, for a better knowledge of what type of ingredients to use and in what quantities. The analysis were only based on the two vegetarian “empadas” with wheat dough, due to the impossibility of the company to provide the respective samples of sardine “empada”. The results from the microbiological analysis indicated that the product has a satisfactory quality, but at the same time revealed the importance of maintenance of the cold system through all the process. With the nutritional analysis was possible to conclude that the product is well balanced and is within of what was defined as an objective for the product. The sensorial analysis revealed a good acceptance of the product, and is worth investment in market introduction. It’s also possible to say that there is a clear preference for one type of filling

Descrição da biodiversidade terrestre dos Açores

Os Açores constituem um arquipélago de nove ilhas oceânicas isoladas, onde os organismos terrestres chegaram através do vento, do mar, noutros animais e, nos tempos históricos, com a ajuda humana. Este capítulo analisa de forma detalhada aquilo que se conhece sobre a biodiversidade terrestre dos Açores. Para tal analisámos os quatro grandes grupos de organismos listados no capítulo 4: Bryophyta (musgos, antocerotas e hepáticas), Pteridophyta e Spermatophyta (fetos e fanerogâmicas), Mollusca (lesmas e caracóis) e Arthropoda (centopeias, diplópodes, crustáceos, aranhas, ácaros, insectos, etc.). O número total de espécies e/ou subespécies dos Açores pertencentes aos quatro grupos de organismos acima referidos é de cerca de 3705 (3666 espécies e 224 subespécies). No entanto, adicionando outros grupos como os vertebrados (Chordata, Vertebrata), anelídeos (Annelida), nemátodos (Nematoda) e líquenes, aquele número sobe para 4487 espécies e/ou subspecies (4443 espécies e 232 subespécies). O número total de espécies e/ou subespécies endémicas dos Açores pertencentes aos Bryophyta, Pteridophyta, Spermatophyta, Mollusca e Arthropoda totaliza as 393 (384 espécies e 44 subespécies). Os filos animais são os mais diversos em taxa endémicos (Mollusca = 49; Arthropoda = 267), com cerca de 80 % dos endemismos dos Açores. Deve ser ainda de assinalar a elevada percentagem de endemismo nos caracóis e lesmas (Mollusca) terrestres dos Açores, com cerca de 44% de endemismo. As plantas vasculares possuem 68 endemismos e os briófitos 9. Usando um estimador não paramétrico, a estimativa conservadora da riqueza de taxa endémicos terrestres de briófitos, plantas vasculares, moluscos e artrópodes rondará 530 taxa, pelo que apenas 77% dos endemismos dos Açores serão conhecidos. Em apenas alguns géneros se verificou uma taxa de especiação elevada, na sua maior parte pertencentes aos filos Mollusca e Arthropoda. A maior parte das espécies de artrópodes e moluscos endémicos são conhecidas apenas de uma ilha, enquanto que, nas plantas, uma grande fracção das espécies ocorre na maioria das ilhas. A análise das proporções das várias categorias de colonização mostra que uma grande proporção da phanerofauna de artrópodes e da flora de plantas vasculares do arquipélago é constituída por espécies introduzidas. Deste modo, as invasões por espécies exóticas constituem um problema actual e terão impactos futuros na biodiversidade dos Açores, criando um padrão de uniformização da fauna e flora. Os Açores constituem o arquipélago da Macaronésia geologicamente mais recente, estando situado mais a norte. As suas nove ilhas isoladas no meio do oceano Atlântico possuem uma grande diversidade de histórias geológicas e constituem laboratórios ecológicos e evolutivos extraordinários. Torna-se cada vez mais importante um esforço adicional nos estudos de taxonomia e ecologia de comunidades que envolvam o estudo de grupos taxonómicos mal conhecidos (fungos, líquenes, muitos grupos de artrópodes) mas também a revisão taxonómica de muitas espécies de briófitos e plantas vasculares.ABSTRACT: The Azores is a remote oceanic archipelago of nine islands where the terrestrial organisms arrived by wind, on the sea, on other animals and on historical times by human assistance. This chapter highlights what we know about Azorean terrestrial biodiversity. Four important terrestrial taxonomic groups listed in Chapter 4 are analysed in detail: Bryophyta (mosses, liverworts), Pteridophyta and Spermatophyta (ferns and phanerogamics), Mollusca (slugs and snails) and Arthropoda (millipedes, centipedes, mites, spiders, insects, etc.). Currently the total number of terrestrial species and/or subspecies of the above mentioned organisms in the Azores is estimated of about 3705 (3666 species and 224 subspecies). However, if we add other groups like vertebrates (Chordata, Vertebrata), annelids (Annelida), nematodes (Nematoda) and lichens, this number reaches 4487 species and/or subspecies (4443 species and 232 subspecies). The total number of endemic species and/or subspecies from the Azores belonging to Bryophyta, Pteridophyta, Spermatophyta, Mollusca and Arthropod is about 393 (384 species and 44 subspecies). The animals Phyla are the most diverse in endemic taxa (Mollusca = 49; Arthropoda = 267), comprising about 80% of the Azorean endemics. The percentage of endemismo within Mollusca (44%) is remarkable. Vascular plants have 68 endemic species while bryophytes have 9 endemics. Using a non-parametric estimator we obtained a conservative estimate for endemic Azorean terrestrial vascular plants, bryophytes, molluscs and arthropods around 530 taxa, which mean that only about 77% have already been described. In only some genera there was a substantial inter and intra-island speciation, most cases occurring in Mollusca and Arthropoda. Most of the endemic arthropods and molluscs are known in only one island, whereas in plants a large proportion of species occur in most islands. Na analysis of the proportions of the colonization categories in arthropods and vascular plants shows that a major proportion of the species are introduced. Therefore, invasions of alien organisms are an actual and future environmental threat in the Azores, creating a pattern of biotic homogenization that is of great contemporary concern. The Azores is the northernmost and the most recent Macaronesian archipelago. The nine islands, isolated in the middle of the Atlantic, with different geological histories, are wonderful ecological and evolutionary laboratories. An additional effort on taxonomic and community-level research implies the detailed examination of poorly studied groups (fungi, lichens, many arthropod groups), but a revision of the taxonomic status of many bryophyte and vascular plants is also deeply needed

Impact of COVID-19 on cardiovascular testing in the United States versus the rest of the world

Objectives: This study sought to quantify and compare the decline in volumes of cardiovascular procedures between the United States and non-US institutions during the early phase of the coronavirus disease-2019 (COVID-19) pandemic. Background: The COVID-19 pandemic has disrupted the care of many non-COVID-19 illnesses. Reductions in diagnostic cardiovascular testing around the world have led to concerns over the implications of reduced testing for cardiovascular disease (CVD) morbidity and mortality. Methods: Data were submitted to the INCAPS-COVID (International Atomic Energy Agency Non-Invasive Cardiology Protocols Study of COVID-19), a multinational registry comprising 909 institutions in 108 countries (including 155 facilities in 40 U.S. states), assessing the impact of the COVID-19 pandemic on volumes of diagnostic cardiovascular procedures. Data were obtained for April 2020 and compared with volumes of baseline procedures from March 2019. We compared laboratory characteristics, practices, and procedure volumes between U.S. and non-U.S. facilities and between U.S. geographic regions and identified factors associated with volume reduction in the United States. Results: Reductions in the volumes of procedures in the United States were similar to those in non-U.S. facilities (68% vs. 63%, respectively; p = 0.237), although U.S. facilities reported greater reductions in invasive coronary angiography (69% vs. 53%, respectively; p < 0.001). Significantly more U.S. facilities reported increased use of telehealth and patient screening measures than non-U.S. facilities, such as temperature checks, symptom screenings, and COVID-19 testing. Reductions in volumes of procedures differed between U.S. regions, with larger declines observed in the Northeast (76%) and Midwest (74%) than in the South (62%) and West (44%). Prevalence of COVID-19, staff redeployments, outpatient centers, and urban centers were associated with greater reductions in volume in U.S. facilities in a multivariable analysis. Conclusions: We observed marked reductions in U.S. cardiovascular testing in the early phase of the pandemic and significant variability between U.S. regions. The association between reductions of volumes and COVID-19 prevalence in the United States highlighted the need for proactive efforts to maintain access to cardiovascular testing in areas most affected by outbreaks of COVID-19 infection

Global age-sex-specific mortality, life expectancy, and population estimates in 204 countries and territories and 811 subnational locations, 1950–2021, and the impact of the COVID-19 pandemic: a comprehensive demographic analysis for the Global Burden of Disease Study 2021

Background: Estimates of demographic metrics are crucial to assess levels and trends of population health outcomes. The profound impact of the COVID-19 pandemic on populations worldwide has underscored the need for timely estimates to understand this unprecedented event within the context of long-term population health trends. The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2021 provides new demographic estimates for 204 countries and territories and 811 additional subnational locations from 1950 to 2021, with a particular emphasis on changes in mortality and life expectancy that occurred during the 2020–21 COVID-19 pandemic period. Methods: 22 223 data sources from vital registration, sample registration, surveys, censuses, and other sources were used to estimate mortality, with a subset of these sources used exclusively to estimate excess mortality due to the COVID-19 pandemic. 2026 data sources were used for population estimation. Additional sources were used to estimate migration; the effects of the HIV epidemic; and demographic discontinuities due to conflicts, famines, natural disasters, and pandemics, which are used as inputs for estimating mortality and population. Spatiotemporal Gaussian process regression (ST-GPR) was used to generate under-5 mortality rates, which synthesised 30 763 location-years of vital registration and sample registration data, 1365 surveys and censuses, and 80 other sources. ST-GPR was also used to estimate adult mortality (between ages 15 and 59 years) based on information from 31 642 location-years of vital registration and sample registration data, 355 surveys and censuses, and 24 other sources. Estimates of child and adult mortality rates were then used to generate life tables with a relational model life table system. For countries with large HIV epidemics, life tables were adjusted using independent estimates of HIV-specific mortality generated via an epidemiological analysis of HIV prevalence surveys, antenatal clinic serosurveillance, and other data sources. Excess mortality due to the COVID-19 pandemic in 2020 and 2021 was determined by subtracting observed all-cause mortality (adjusted for late registration and mortality anomalies) from the mortality expected in the absence of the pandemic. Expected mortality was calculated based on historical trends using an ensemble of models. In location-years where all-cause mortality data were unavailable, we estimated excess mortality rates using a regression model with covariates pertaining to the pandemic. Population size was computed using a Bayesian hierarchical cohort component model. Life expectancy was calculated using age-specific mortality rates and standard demographic methods. Uncertainty intervals (UIs) were calculated for every metric using the 25th and 975th ordered values from a 1000-draw posterior distribution. Findings: Global all-cause mortality followed two distinct patterns over the study period: age-standardised mortality rates declined between 1950 and 2019 (a 62·8% [95% UI 60·5–65·1] decline), and increased during the COVID-19 pandemic period (2020–21; 5·1% [0·9–9·6] increase). In contrast with the overall reverse in mortality trends during the pandemic period, child mortality continued to decline, with 4·66 million (3·98–5·50) global deaths in children younger than 5 years in 2021 compared with 5·21 million (4·50–6·01) in 2019. An estimated 131 million (126–137) people died globally from all causes in 2020 and 2021 combined, of which 15·9 million (14·7–17·2) were due to the COVID-19 pandemic (measured by excess mortality, which includes deaths directly due to SARS-CoV-2 infection and those indirectly due to other social, economic, or behavioural changes associated with the pandemic). Excess mortality rates exceeded 150 deaths per 100 000 population during at least one year of the pandemic in 80 countries and territories, whereas 20 nations had a negative excess mortality rate in 2020 or 2021, indicating that all-cause mortality in these countries was lower during the pandemic than expected based on historical trends. Between 1950 and 2021, global life expectancy at birth increased by 22·7 years (20·8–24·8), from 49·0 years (46·7–51·3) to 71·7 years (70·9–72·5). Global life expectancy at birth declined by 1·6 years (1·0–2·2) between 2019 and 2021, reversing historical trends. An increase in life expectancy was only observed in 32 (15·7%) of 204 countries and territories between 2019 and 2021. The global population reached 7·89 billion (7·67–8·13) people in 2021, by which time 56 of 204 countries and territories had peaked and subsequently populations have declined. The largest proportion of population growth between 2020 and 2021 was in sub-Saharan Africa (39·5% [28·4–52·7]) and south Asia (26·3% [9·0–44·7]). From 2000 to 2021, the ratio of the population aged 65 years and older to the population aged younger than 15 years increased in 188 (92·2%) of 204 nations. Interpretation: Global adult mortality rates markedly increased during the COVID-19 pandemic in 2020 and 2021, reversing past decreasing trends, while child mortality rates continued to decline, albeit more slowly than in earlier years. Although COVID-19 had a substantial impact on many demographic indicators during the first 2 years of the pandemic, overall global health progress over the 72 years evaluated has been profound, with considerable improvements in mortality and life expectancy. Additionally, we observed a deceleration of global population growth since 2017, despite steady or increasing growth in lower-income countries, combined with a continued global shift of population age structures towards older ages. These demographic changes will likely present future challenges to health systems, economies, and societies. The comprehensive demographic estimates reported here will enable researchers, policy makers, health practitioners, and other key stakeholders to better understand and address the profound changes that have occurred in the global health landscape following the first 2 years of the COVID-19 pandemic, and longer-term trends beyond the pandemic

Guided Bone Regeneration in the Edentulous Atrophic Maxilla Using Deproteinized Bovine Bone Mineral (DBBM) Combined with Platelet-Rich Fibrin (PRF)—A Prospective Study

Background: Bone regeneration procedures represent a major challenge in oral surgery. This study aimed to evaluate a composite PRF/particulate xenograft in guided bone regeneration. Methods: Edentulous patients with horizontal ridge deficiencies in the anterior maxilla and candidates to an immediate-loading full-arch rehabilitation were included. Horizontal linear measurements indicating bone gain were assessed from computer beam computer tomography (CBCT) scans obtained at pre-surgery, post-surgery, and the 12-month follow-up. Mean bone values were presented as mean ± 95% CI. Non-parametric tests were used as appropriate, and the effect size was calculated with Cohen’s d repeated measures. Results: Eighteen patients were rehabilitated with 72 implants. The mean horizontal bone width was 4.47 [4.13–4.80] mm pre-surgically, 9.25 [8.76–9.75] mm post-surgically, and 7.71 [7.28–8.14] mm 12 months after. Conclusions: PRF associated with a xenograft seems to promote an effective horizontal bone gain. Randomized clinical trials are needed to confirm the benefits of this surgical approach
