Agrio et Emulsio – development of fruity mustard creams
Agrio et Emulsio project (POCI-01-0145-FEDER-023583) presents an proposal in the areas
of vinegar products and food emulsions. Combining technical features with mediterranean
traditions and Nouvelle Cuisine, two prototypes of fruity mustards are undergoing final
development, valuing regional raw materials and profiling into the gourmet/vegan/veggie
markets. Mustard creams are oil-in-water emulsions but its practice is linked to vinegar
traditions since the thirteenth century, in France, with the foundation of the first confraternity
of Maîtres Vinaigrier-Moutardier. Thus, by applying the ancestral practice, mustard (seeds,
fragments, powder) was first submitted to maturation studies, varying the type of vinegar and
the time of immersion/contact. Maturation reached equilibrium on the 16th day, but pH
evolution shows a practically stationary state from the 7th. Best results were obtained with
seeds and powdered mustards in red wine vinegar, 4 %(m/v) acidity. The assays were carried
out at room temperature using Sinapis Alba (Linnaeus) mustard species. Prototyping
articulated technical, analytical (physicochemical, rheological, microbiological) and sensory
tests. Each final prototype has a distinct profile of ingredients, mustard, fruits (raspberry and
beet or blueberry), olive oil, water, salt, sugar, honey and spices. Both creams retain the sui
generis taste of mustard tinted with the fruit flavour plus an innovative pink colour.info:eu-repo/semantics/publishedVersio
New food, new technology: innovative spreadable cream with strawberry syrup
A strawberry spreadable cream was developed, valorizing regional raw materials, contributing to food waste reduction and
agri-food ecosystem sustainability. Spreadable creams are water-in-oil emulsions whose lipid phase normally contains a blend
of vegetable oils, natural colourants, stabilizers, emulsifers, favourings, antioxidants, lecithin, and fat-soluble vitamins. The
aqueous phase normally contains skim milk proteins and small quantities of other ingredients, such as salt, preservatives,
thickeners, and water-soluble vitamins. The methodology involved the experimental technological development articulated
with microbiological, proximal, physicochemical, and sensorial analysis. This new product revealed nutritional advantages
over similar products already on the market. The fnal prototype was subjected to food pairing and food design with incre mental acceptance according to gastronomic use, in addition to its direct use as a spreadable cream. This work was part of
the project Agrio et Emulsio—new products development (POCI-01-0145-FEDER-023583), whose main objective was the
formulation and design of innovative food emulsions based on processed raw materials, with potential application in certain
markets such as gourmet, diet, and vegan.info:eu-repo/semantics/publishedVersio
Sanitation of chicken eggs by ionizing radiation: functional and nutritional assessment
Alternative technologies must be developed and implemented considering sanitation and preservation of eggs mainly for risk population. Food irradiation is an alternative to free Salmonella spp. and Campylobacter spp. eggs, as a low dose point to a safety assurance. This study presents the correlation between irradiation doses (0.5 kGy up to 5 kGy at dose rate of 1.0 kGy/h) and some of functional and nutritional egg properties. Viscosimetry of non-irradiated and irradiated eggs was evaluated by means of VT550 Haake with an NV sensor and co-axes cylinders. After irradiation at 5 kGy, the yolk colour die (pale yellow) and the white egg was modified to a turbid yellow. The Cross equation was utilized to viscosimetry curves. Based on the assymptotics viscosimetry data indicated that increase of doses corresponds to an increase of the yolk and a decrease of white egg viscosimetry as such a Newton behaviour. Irradiation effects on nutritional properties were evaluated by means of egg protein patterns that were assessed by polyacrylamide gel electrophoresis. Lipids were identified by TLC. Based on results the sanitation dose is lower than the limit dose for the decrease of the main eggs properties
Evaluation of potential of gamma radiation as a conservation treatment for blackberry fruits
BACKGROUND: Blackberries consumption has been associated with health benefits. However, these fruits present a short shelf-life. Thus, food irradiation is a potential alternative technology for conservation of these fruits without use of chemicals. OBJECTIVE: Analyse the potentiality of gamma radiation as a decontamination method for blackberry fruits. METHODS: Fresh packed blackberries were irradiated in a Co-60 source at two doses (1.0 and 1.5 kGy). Bioburden, physical and rheological, sensorial and total soluble content parameters were assessed before irradiation, immediately after and at two days storage time at 4°C. RESULTS: The characterization of blackberries microbiota point out to an average bioburden value of 104 CFU/g and to a microbial population predominantly composed by filamentous fungi. The inactivation studies on the blackberries mesophilic population indicated a limited microbial inactivation (<1 log decimal reduction) for the applied radiation doses, being the surviving population mainly constituted by filamentous fungi and yeast. No effect of irradiation on colour of blackberries was observed. Concerning texture parameters, no significant differences were observed in both fracturability and firmness between non-irradiated and irradiated blackberries immediately after irradiation. In blackberries stored for two days, both parameters were slightly lower in irradiated blackberries, compared to non-irradiated blackberries. The performed sensorial analysis indicated a similar acceptability among irradiated and non-irradiated fruits. CONCLUSION: This work reveals gamma irradiation treatment potential since no major impact was detected on blackberries physical, rheological and sensory attributes. Further studies with longer periods of storage are needed to elucidate the advantages of irradiation as a conservation treatment.© 2013 - IOS Press and the authors. All rights reserved
Produção in vitro de embriões ovinos a partir de oócitos coletados durante os períodos seco e chuvoso
Objetivou-se determinar o efeito dos períodos seco (Julho a Janeiro) e chuvoso (Fevereiro a Junho) sobre a produção in vitro de embriões ovinos. Os ovários foram coletados em abatedouro e transportados ao laboratório em recipiente térmico contendo solução fisiológica aquecida a 38 oC. Os ovócitos foram recuperados de folículos medindo 2 a 6 mm e selecionados com base na sua morfologia. Utilizou-se 1231 ovócitos na estação seca e 1252 na chuvosa em 12 replícas, os quais foram submetidos à maturação in vitro, fecundação in vitro e cultivo in vitro no mesmo ambiente atmosférico. As taxas de clivagem e de desenvolvimento embrionário até os estádios de 8 a 16 células, mórula e blastocisto foram avaliadas, respectivamente, no 3o, 4o, 5o e 8o dia após a fecundação in vitro. Os blastocistos foram avaliados quanto à incidência de apoptose determinada pela fragmentação do DNA. A taxa de ovócitos viáveis para a fecundação in vitro, clivagem e número de embriões no estádio entre 8 e 16 células foi maior (P < 0,05) durante o período chuvoso. No entanto, as taxas de maturação in vitro, de mórula, de blastocistos e de apoptose não diferiram (P > 0,05) entre os períodos. Os resultados permitem concluir que não existe influência climática sobre a maturação in vitro de ovócitos, bem como sobre a produção in vitro de embriões da espécie ovina
Global economic burden of unmet surgical need for appendicitis
Background: There is a substantial gap in provision of adequate surgical care in many low-and middle-income countries. This study aimed to identify the economic burden of unmet surgical need for the common condition of appendicitis. Methods: Data on the incidence of appendicitis from 170 countries and two different approaches were used to estimate numbers of patients who do not receive surgery: as a fixed proportion of the total unmet surgical need per country (approach 1); and based on country income status (approach 2). Indirect costs with current levels of access and local quality, and those if quality were at the standards of high-income countries, were estimated. A human capital approach was applied, focusing on the economic burden resulting from premature death and absenteeism. Results: Excess mortality was 4185 per 100 000 cases of appendicitis using approach 1 and 3448 per 100 000 using approach 2. The economic burden of continuing current levels of access and local quality was US 73 141 million using approach 2. The economic burden of not providing surgical care to the standards of high-income countries was 75 666 million using approach 2. The largest share of these costs resulted from premature death (97.7 per cent) and lack of access (97.0 per cent) in contrast to lack of quality. Conclusion: For a comparatively non-complex emergency condition such as appendicitis, increasing access to care should be prioritized. Although improving quality of care should not be neglected, increasing provision of care at current standards could reduce societal costs substantially
Laparoscopy in management of appendicitis in high-, middle-, and low-income countries: a multicenter, prospective, cohort study.
BACKGROUND: Appendicitis is the most common abdominal surgical emergency worldwide. Differences between high- and low-income settings in the availability of laparoscopic appendectomy, alternative management choices, and outcomes are poorly described. The aim was to identify variation in surgical management and outcomes of appendicitis within low-, middle-, and high-Human Development Index (HDI) countries worldwide. METHODS: This is a multicenter, international prospective cohort study. Consecutive sampling of patients undergoing emergency appendectomy over 6 months was conducted. Follow-up lasted 30 days. RESULTS: 4546 patients from 52 countries underwent appendectomy (2499 high-, 1540 middle-, and 507 low-HDI groups). Surgical site infection (SSI) rates were higher in low-HDI (OR 2.57, 95% CI 1.33-4.99, p = 0.005) but not middle-HDI countries (OR 1.38, 95% CI 0.76-2.52, p = 0.291), compared with high-HDI countries after adjustment. A laparoscopic approach was common in high-HDI countries (1693/2499, 67.7%), but infrequent in low-HDI (41/507, 8.1%) and middle-HDI (132/1540, 8.6%) groups. After accounting for case-mix, laparoscopy was still associated with fewer overall complications (OR 0.55, 95% CI 0.42-0.71, p < 0.001) and SSIs (OR 0.22, 95% CI 0.14-0.33, p < 0.001). In propensity-score matched groups within low-/middle-HDI countries, laparoscopy was still associated with fewer overall complications (OR 0.23 95% CI 0.11-0.44) and SSI (OR 0.21 95% CI 0.09-0.45). CONCLUSION: A laparoscopic approach is associated with better outcomes and availability appears to differ by country HDI. Despite the profound clinical, operational, and financial barriers to its widespread introduction, laparoscopy could significantly improve outcomes for patients in low-resource environments.

Global, regional, and national comparative risk assessment of 79 behavioural, environmental and occupational, and metabolic risks or clusters of risks in 188 countries, 1990-2013: A systematic analysis for the Global Burden of Disease Study 2013
Background: The Global Burden of Disease, Injuries, and Risk Factor study 2013 (GBD 2013) is the first of a series of annual updates of the GBD. Risk factor quantification, particularly of modifiable risk factors, can help to identify emerging threats to population health and opportunities for prevention. The GBD 2013 provides a timely opportunity to update the comparative risk assessment with new data for exposure, relative risks, and evidence on the appropriate counterfactual risk distribution. Methods: Attributable deaths, years of life lost, years lived with disability, and disability-adjusted life-years (DALYs) have been estimated for 79 risks or clusters of risks using the GBD 2010 methods. Risk-outcome pairs meeting explicit evidence criteria were assessed for 188 countries for the period 1990-2013 by age and sex using three inputs: risk exposure, relative risks, and the theoretical minimum risk exposure level (TMREL). Risks are organised into a hierarchy with blocks of behavioural, environmental and occupational, and metabolic risks at the first level of the hierarchy. The next level in the hierarchy includes nine clusters of related risks and two individual risks, with more detail provided at levels 3 and 4 of the hierarchy. Compared with GBD 2010, six new risk factors have been added: handwashing practices, occupational exposure to trichloroethylene, childhood wasting, childhood stunting, unsafe sex, and low glomerular filtration rate. For most risks, data for exposure were synthesised with a Bayesian metaregression method, DisMod-MR 2.0, or spatial-temporal Gaussian process regression. Relative risks were based on meta-regressions of published cohort and intervention studies. Attributable burden for clusters of risks and all risks combined took into account evidence on the mediation of some risks such as high body-mass index (BMI) through other risks such as high systolic blood pressure and high cholesterol. Findings: All risks combined account for 57·2% (95% uncertainty interval [UI] 55·8-58·5) of deaths and 41·6% (40·1-43·0) of DALYs. Risks quantified account for 87·9% (86·5-89·3) of cardiovascular disease DALYs, ranging to a low of 0% for neonatal disorders and neglected tropical diseases and malaria. In terms of global DALYs in 2013, six risks or clusters of risks each caused more than 5% of DALYs: dietary risks accounting for 11·3 million deaths and 241·4 million DALYs, high systolic blood pressure for 10·4 million deaths and 208·1 million DALYs, child and maternal malnutrition for 1·7 million deaths and 176·9 million DALYs, tobacco smoke for 6·1 million deaths and 143·5 million DALYs, air pollution for 5·5 million deaths and 141·5 million DALYs, and high BMI for 4·4 million deaths and 134·0 million DALYs. Risk factor patterns vary across regions and countries and with time. In sub-Saharan Africa, the leading risk factors are child and maternal malnutrition, unsafe sex, and unsafe water, sanitation, and handwashing. In women, in nearly all countries in the Americas, north Africa, and the Middle East, and in many other high-income countries, high BMI is the leading risk factor, with high systolic blood pressure as the leading risk in most of Central and Eastern Europe and south and east Asia. For men, high systolic blood pressure or tobacco use are the leading risks in nearly all high-income countries, in north Africa and the Middle East, Europe, and Asia. For men and women, unsafe sex is the leading risk in a corridor from Kenya to South Africa. Interpretation: Behavioural, environmental and occupational, and metabolic risks can explain half of global mortality and more than one-third of global DALYs providing many opportunities for prevention. Of the larger risks, the attributable burden of high BMI has increased in the past 23 years. In view of the prominence of behavioural risk factors, behavioural and social science research on interventions for these risks should be strengthened. Many prevention and primary care policy options are available now to act on key risks
