Inactivation mechanisms of human adenovirus by e-beam irradiation in water environments
This study aims to study the kinetics and mechanisms of human adenovirus inactivation by electron beam. Human adenovirus type 5 (HAdV-5) was inoculated in two types of aqueous substrates (phosphate-buffered saline - PBS, domestic wastewater - WW) treated by electron beam at a dose range between 3 and 21 kGy. Samples were evaluated for virus infectivity, PCR amplification of fragments of HAdV-5 genome and abundance and antigenicity of the virion structural proteins. The maximum reduction in viral titre, in plaque-forming units (PFU) per millilitre, was about 7 and 5 log PFU/mL for e-beam irradiation at 20 kGy in PBS and 19 ...

A 6-Year Update on the Diversity of Methicillin-Resistant Staphylococcus aureus Clones in Africa: A Systematic Review
ConclusionWe observed an increase in the distribution of ST1, ST22, and ST152, but a decline of ST239/241 in Africa. Data on MRSA clones in Africa is still limited. There is a need to strengthen genomic surveillance capacity based on a “One-Health” strategy to prevent and control MRSA in Africa. (Source: Frontiers in Microbiology)

Tuberculosis contact investigation in African Portuguese-speaking countries at End TB Strategy era: a scoping review
Conclusion
This review highlights the scarcity of references on TB contact investigation in PALOP at the End TB Strategy era. Furthermore, it is well clear the importance of an information system that provides actual data for assessing the real impact of such interventions in controlling the disease in African Portuguese-speaking countries.

IJERPH, Vol. 19, Pages 3834: Tuberculosis and Migrant Pathways in an Urban Setting: A Mixed-Method Case Study on a Treatment Centre in the Lisbon Metropolitan Area, Portugal
raveiro
Tuberculosis (TB) is an infectious disease associated with poverty. In the European Union TB tends to concentrate in urban settings. In Lisbon, previous studies revealed, the presence of migrant populations from a high endemic country, is one of the risk factors contributing to TB. To better understand TB in foreign-born individuals in the Lisbon Metropolitan Area, a mixed-method case study was undertaken on a TB treatment centre in a high-risk part of urban Portugal. Quantitatively, annual TB cases were analysed from 2008 to 2018, dividing foreign-origin cases into recent migrants and long-term migrants. Quali...

Essential Metals and Trace Elements in Cereals and Their Derivatives Commercialized and Consumed in Cape Verde
Biol Trace Elem Res. 2022 Feb 28. doi: 10.1007/s12011-022-03158-x. Online ahead of print.ABSTRACTCereals and their derivatives are basic foods in the human diet and a source of minerals, but the content of elements may vary depending on the type of cereal or its processing. The levels of Na, K, Ca, Mg, Fe, Cu, Zn, Mo, Co, and Mn have been determined in 126 samples of cereals and cereal derivatives (rice, corn gofio, corn flour, wheat flour, corn, and wheat) commercialized and consumed in Cape Verde using an inductively coupled plasma-optical emission spectrometer (ICP-OES) after a wet microwave digestion process. Some elem...

Comparative study of organic contaminants in agricultural soils at the archipelagos of the Macaronesia
In this study, 218 pesticides, 49 persistent organic pollutants, 37 pharmaceutical active compounds and 6 anticoagulant rodenticides were analyzed in 139 agricultural soil samples collected between 2018 and 2020 in the Macaronesia. This region comprised four inhabited archipelagos (Azores, Canary Islands, Cape Verde, and Madeira) for which agriculture is an important and traditional economic activity. To our knowledge, this is the first study on the levels of organic compound contamination of agricultural soils of the Macaronesia. As expected, the most frequently detected compounds were pesticides, mainly fungicides and in...

Potential life years lost to COVID-19 in 17 countries during the pandemic period, up to August 2020
ConclusionsSouth America, and males were found to be the most affected by COVID-19. Ongoing monitoring of the COVID-19 mortality impact is essential in order to assess health system performances, control measures, and identify vulnerable populations. Differences in mortality burden among populations will help public health officials in their efforts to minimize the COVID-19 mortality burden on a local, and on a global level.Key messagesUp to August 2020, COVID-19 was a cause of premature mortality in all the participating countries, with South America and males to be more affected.The timing of the pandemic, seasonal trend...

Evaluation of naturally occurring radionuclides (K, Th and U) in volcanic soils from Fogo Island, Cape Verde
AbstractNatural radionuclides K, Th and U were evaluated for the first time on volcanic soils of Fogo Island (Cape Verde) aiming to contribute for the background concentration of radiogenic elements in these soils, assessing radiation risk, and allowing accurate chronological luminescence studies. Potassium and particularly U appear to be more mobilized in the older soils, with a high radon loss when compared to recent ones. External dose rate varies between 0.97 and 3.47 Gy/y. The results obtained in this work are a benchmark for further studies, particularly for the evaluation of modifications due to the 2014–2015 vo...
