Objective: To analyze the degree of physical disability in the elderly population affected by leprosy in Bahia State, between 2001 and 2012. Methods: The data relating to cases of leprosy was obtained from National System of Notifiable Diseases. Variables analyzed gender, age, race/color, education level, clinical and operational classification, degree of physical incapacity in diagnosis and discharge. Epidemiological indicators related to physical incapacity were calculated. Results: The leprosy features high magnitude in the elderly population, with a coefficient of detection of new cases higher than the general population, situated at a hyperendemic level. As to the epidemiological profile of leprosy in elderly, stands out: men, age 60 to 69 years, white race, low education level, dimorphic clinical manifestation and multibacillary operational classification. 36.25% of diagnosed cases had a physical incapacity at the time of diagnosis, with emphasis on the masculine gender. Conclusion: The high proportion of individuals with physical incapacity at the time of diagnosis suggests late diagnosis and hidden prevalence of the disease, mostly in Individuals of the male gender.Objetivo: Analisar o grau de incapacidade física na população idosa afetada pela hanseníase no estado da Bahia, entre 2001 e 2012.

SARS-CoV-2 introductions and early dynamics of the epidemic in Portugal

Genomic surveillance of SARS-CoV-2 in Portugal was rapidly implemented by the National Institute of Health in the early stages of the COVID-19 epidemic, in collaboration with more than 50 laboratories distributed nationwide. Methods By applying recent phylodynamic models that allow integration of individual-based travel history, we reconstructed and characterized the spatio-temporal dynamics of SARSCoV-2 introductions and early dissemination in Portugal. Results We detected at least 277 independent SARS-CoV-2 introductions, mostly from European countries (namely the United Kingdom, Spain, France, Italy, and Switzerland), which were consistent with the countries with the highest connectivity with Portugal. Although most introductions were estimated to have occurred during early March 2020, it is likely that SARS-CoV-2 was silently circulating in Portugal throughout February, before the first cases were confirmed. Conclusions Here we conclude that the earlier implementation of measures could have minimized the number of introductions and subsequent virus expansion in Portugal. This study lays the foundation for genomic epidemiology of SARS-CoV-2 in Portugal, and highlights the need for systematic and geographically-representative genomic surveillance.We gratefully acknowledge to Sara Hill and Nuno Faria (University of Oxford) and Joshua Quick and Nick Loman (University of Birmingham) for kindly providing us with the initial sets of Artic Network primers for NGS; Rafael Mamede (MRamirez team, IMM, Lisbon) for developing and sharing a bioinformatics script for sequence curation (https://github.com/rfm-targa/BioinfUtils); Philippe Lemey (KU Leuven) for providing guidance on the implementation of the phylodynamic models; Joshua L.

Repercussão da terapia de suplementação de proteína em detrimento das alterações na composição muscular de idosos: uma revisão: Repercussion of protein supplementation therapy to the detriment of changes in muscle composition in the elderly: a review

INTRODUÇÃO: O ato de envelhecer traz consigo inúmeras mudanças fisiológicas, dentre elas, destaca-se a sarcopenia, que por vezes pode levar a perda da capacidade funcional, podendo prejudicar a mobilidade e por fim acarretar em acidentes graves ou mortes. A atual concentração diária recomendada de proteína por quilograma não foi projetada para uma população em fase de envelhecimento, o que pode levar a uma concentração de proteína insuficiente. A suplementação proteica surgiu como forma alternativa de preservar a manutenção muscular. OBJETIVO: Analisar os efeitos da suplementação proteica na manutenção da capacidade funcional muscular na população idosa. METODOLOGIA: Para tanto, foi realizada uma revisão integrativa da literatura de aspecto qualitativo, no qual, a partir de uma pesquisa em bases de dados selecionadas, baseou-se em estudos que apresentaram efeitos da suplementação proteica na manutenção da capacidade funcional muscular de idosos. Ao final foram selecionados seis estudos que contemplavam o tema em questão. RESULTADOS E DISCUSSÃO: A melhora do estado nutricional está relacionada ao desempenho muscular, com base nisso, foram analisados nos estudos os seguintes aspectos: ganho de massa muscular, exercício físico em jejum, membros inferiores, velocidade da marcha e outros parâmetros funcionais e 25-hidroxivitamina D, todos colocando-se em comparação com a suplementação proteica como forma intervencionista e de manutenção da capacidade funcional muscular. Ainda, foi realizada uma análise da suplementação dietética com aminoácidos de cadeia ramificada (BCAAs) em relação a desnutrição. CONCLUSÃO: A análise dos dados supracitados revelou a relevância da busca pela melhoria na qualidade de vida e bem-estar da população senil, de maneira que o consumo diário recomendado de proteína seja preconizado como principal medida para manutenção da massa muscular nesta parcela populacional. Deve-se estimular o consumo diário de alimentos ricos em proteínas, tais como carnes, ovos, leite e derivados e suplementos alimentares, quando sua prescrição se faz necessária. Diante da corroboração da sarcopenia no aumento da incidência de quedas em idosos, se faz necessário orientar e estimular a população senil para a prática regular de exercício físico resistido, além do acompanhamento de equipe multidisciplinar

Robust estimation of bacterial cell count from optical density

Optical density (OD) is widely used to estimate the density of cells in liquid culture, but cannot be compared between instruments without a standardized calibration protocol and is challenging to relate to actual cell count. We address this with an interlaboratory study comparing three simple, low-cost, and highly accessible OD calibration protocols across 244 laboratories, applied to eight strains of constitutive GFP-expressing E. coli. Based on our results, we recommend calibrating OD to estimated cell count using serial dilution of silica microspheres, which produces highly precise calibration (95.5% of residuals <1.2-fold), is easily assessed for quality control, also assesses instrument effective linear range, and can be combined with fluorescence calibration to obtain units of Molecules of Equivalent Fluorescein (MEFL) per cell, allowing direct comparison and data fusion with flow cytometry measurements: in our study, fluorescence per cell measurements showed only a 1.07-fold mean difference between plate reader and flow cytometry data

BacHBerry: BACterial Hosts for production of Bioactive phenolics from bERRY fruits

BACterial Hosts for production of Bioactive phenolics from bERRY fruits (BacHBerry) was a 3-year project funded by the Seventh Framework Programme (FP7) of the European Union that ran between November 2013 and October 2016. The overall aim of the project was to establish a sustainable and economically-feasible strategy for the production of novel high-value phenolic compounds isolated from berry fruits using bacterial platforms. The project aimed at covering all stages of the discovery and pre-commercialization process, including berry collection, screening and characterization of their bioactive components, identification and functional characterization of the corresponding biosynthetic pathways, and construction of Gram-positive bacterial cell factories producing phenolic compounds. Further activities included optimization of polyphenol extraction methods from bacterial cultures, scale-up of production by fermentation up to pilot scale, as well as societal and economic analyses of the processes. This review article summarizes some of the key findings obtained throughout the duration of the project

Global, regional, and national age-sex-specific mortality for 282 causes of death in 195 countries and territories, 1980-2017: a systematic analysis for the Global Burden of Disease Study 2017.

BACKGROUND: Global development goals increasingly rely on country-specific estimates for benchmarking a nation's progress. To meet this need, the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2016 estimated global, regional, national, and, for selected locations, subnational cause-specific mortality beginning in the year 1980. Here we report an update to that study, making use of newly available data and improved methods. GBD 2017 provides a comprehensive assessment of cause-specific mortality for 282 causes in 195 countries and territories from 1980 to 2017. METHODS: The causes of death database is composed of vital registration (VR), verbal autopsy (VA), registry, survey, police, and surveillance data. GBD 2017 added ten VA studies, 127 country-years of VR data, 502 cancer-registry country-years, and an additional surveillance country-year. Expansions of the GBD cause of death hierarchy resulted in 18 additional causes estimated for GBD 2017. Newly available data led to subnational estimates for five additional countries-Ethiopia, Iran, New Zealand, Norway, and Russia. Deaths assigned International Classification of Diseases (ICD) codes for non-specific, implausible, or intermediate causes of death were reassigned to underlying causes by redistribution algorithms that were incorporated into uncertainty estimation. We used statistical modelling tools developed for GBD, including the Cause of Death Ensemble model (CODEm), to generate cause fractions and cause-specific death rates for each location, year, age, and sex. Instead of using UN estimates as in previous versions, GBD 2017 independently estimated population size and fertility rate for all locations. Years of life lost (YLLs) were then calculated as the sum of each death multiplied by the standard life expectancy at each age. All rates reported here are age-standardised

31st Annual Meeting and Associated Programs of the Society for Immunotherapy of Cancer (SITC 2016) : part two

Background The immunological escape of tumors represents one of the main ob- stacles to the treatment of malignancies. The blockade of PD-1 or CTLA-4 receptors represented a milestone in the history of immunotherapy. However, immune checkpoint inhibitors seem to be effective in specific cohorts of patients. It has been proposed that their efficacy relies on the presence of an immunological response. Thus, we hypothesized that disruption of the PD-L1/PD-1 axis would synergize with our oncolytic vaccine platform PeptiCRAd. Methods We used murine B16OVA in vivo tumor models and flow cytometry analysis to investigate the immunological background. Results First, we found that high-burden B16OVA tumors were refractory to combination immunotherapy. However, with a more aggressive schedule, tumors with a lower burden were more susceptible to the combination of PeptiCRAd and PD-L1 blockade. The therapy signifi- cantly increased the median survival of mice (Fig. 7). Interestingly, the reduced growth of contralaterally injected B16F10 cells sug- gested the presence of a long lasting immunological memory also against non-targeted antigens. Concerning the functional state of tumor infiltrating lymphocytes (TILs), we found that all the immune therapies would enhance the percentage of activated (PD-1pos TIM- 3neg) T lymphocytes and reduce the amount of exhausted (PD-1pos TIM-3pos) cells compared to placebo. As expected, we found that PeptiCRAd monotherapy could increase the number of antigen spe- cific CD8+ T cells compared to other treatments. However, only the combination with PD-L1 blockade could significantly increase the ra- tio between activated and exhausted pentamer positive cells (p= 0.0058), suggesting that by disrupting the PD-1/PD-L1 axis we could decrease the amount of dysfunctional antigen specific T cells. We ob- served that the anatomical location deeply influenced the state of CD4+ and CD8+ T lymphocytes. In fact, TIM-3 expression was in- creased by 2 fold on TILs compared to splenic and lymphoid T cells. In the CD8+ compartment, the expression of PD-1 on the surface seemed to be restricted to the tumor micro-environment, while CD4 + T cells had a high expression of PD-1 also in lymphoid organs. Interestingly, we found that the levels of PD-1 were significantly higher on CD8+ T cells than on CD4+ T cells into the tumor micro- environment (p < 0.0001). Conclusions In conclusion, we demonstrated that the efficacy of immune check- point inhibitors might be strongly enhanced by their combination with cancer vaccines. PeptiCRAd was able to increase the number of antigen-specific T cells and PD-L1 blockade prevented their exhaus- tion, resulting in long-lasting immunological memory and increased median survival
