Could cattle ranching and soybean cultivation be sustainable? A systematic review and a meta-analysis for the Amazon

2021

Abstract: Tropical forests are being destroyed to make space for agricultural activities with the assumption that they are required to feed the growing global population. Consequently, more sustainable practices are needed to guarantee food security and environmental protection of highly threatened natural biodiversity hotspots like the Amazon rainforest. Cattle ranching and soybean cultivation are by far the greater drivers of land use change and deforestation in the Amazon region. We performed a systematic review of papers related to these two main drivers and a meta-analysis on the effects of sustainable practices on different ecosystem services. The results of the review highlight a lar…

Louseborne relapsing fever in young migrants, sicily, Italy, july-september 2015

2016

To the Editor: During the early 20th century, at the end of World War I, and during World War II, louseborne relapsing fever (LBRF) caused by Borrelia recurrentis was a major public health problem, especially in eastern Europe and northern Africa (1,2). Currently, poor living conditions, famine, war, and refugee camps are major risk factors for epidemics of LBRF in resource-poor countries, such as those in the Horn of Africa (3,4). Increased migration from resource-poor countries and war/violence create new routes for spread of vectorborne diseases. Recently, several cases of LBRF have been reported among asylum seekers from Eritrea in the Netherlands, Switzerland, and Germany (5–8). All of…

Evolutionary processes in the emergence and recent spread of the syphilis agent, Treponema pallidum

2022

Abstract The incidence of syphilis has risen worldwide in the last decade in spite of being an easily treated infection. The causative agent of this sexually transmitted disease is the bacterium Treponema pallidum subspecies pallidum (TPA), very closely related to subsp. pertenue (TPE) and endemicum (TEN), responsible for the human treponematoses yaws and bejel, respectively. Although much focus has been placed on the question of the spatial and temporary origins of TPA, the processes driving the evolution and epidemiological spread of TPA since its divergence from TPE and TEN are not well understood. Here, we investigate the effects of recombination and selection as forces of genetic diver…

LA QUALITÀ DEL MANGO PRODOTTO IN SICILIA, ASPETTI COLTURALI DELLA PAPAYA, DEL LICI E DEL NESPOLO DEL GIAPPONE

2016

L’introduzione di specie arboree da frutto di origine tropicale e subtropicale in Sicilia non è nuova ma solo negli ultimi anni si assiste ad una crescita esponenziale delle superfici investite. Infatti, se alberi come il Nespolo del Giappone fanno ormai parte della nostra cultura frutticola da decenni, mango, lici e papaia fino a qualche anno fa erano poco conosciuti sulle nostre tavole. Nel giro di poco tempo questi frutti hanno conquistato un posto stabile tra le preferenze del consumatore con spazi di mercato in continuo aumento. La coltivazione di questi fruttiferi di origine tropicale presuppone precise risposte sulla fattibilità di nuovi impianti e sulle modalità di conduzione agrono…

Where Did the Money Go? Endogenous Money Creation for International Fraudulent Purposes - The Case of the 2015 Moldovan Banking Scandal

2015

On Monday 4 May 2015, the speaker of Parliament of the Republic of Moldova published the Kroll report on his Internet blog after thousands of people rallied on Sunday 3 May in the capital, Chisinau, to protest against endemic corruption in the country, and demand recovery of the missing billions in the Ilan Shor group scandal. The Kroll report aims at investigating the apparent theft of nearly one-fifth of the country's annual GDP. In a spectacular lender-of-last resort move, the Moldovan central bank was forced to issue some 16 billion lei ($870 million) in emergency loans to keep the economy afloat. The Kroll report focuses on three commercial banks that account for a third of the country…

Spatial data of Ixodes ricinus instar abundance and nymph pathogen prevalence, Scandinavia, 2016-2017.

2020

ticks carry pathogens that can cause disease in both animals and humans, and there is a need to monitor the distribution and abundance of ticks and the pathogens they carry to pinpoint potential high risk areas for tick-borne disease transmission. In a joint Scandinavian study, we measured Ixodes ricinus instar abundance at 159 sites in southern Scandinavia in August-September, 2016, and collected 29,440 tick nymphs at 50 of these sites. We additionally measured abundance at 30 sites in August-September, 2017. We tested the 29,440 tick nymphs in pools of 10 in a Fluidigm real-time PCR chip to screen for 17 different tick-associated pathogens, 2 pathogen groups and 3 tick species. We present…

Association of Urogenital Symptoms with History of Water Contact in Young Women in Areas Endemic for S. haematobium. A Cross-Sectional Study in Rural…

2016

Female genital schistosomiasis is a neglected tropical disease caused by Schistosoma haematobium. Infected females may suffer from symptoms mimicking sexually transmitted infections. We explored if self-reported history of unsafe water contact could be used as a simple predictor of genital schistosomiasis. In a cross-sectional study in rural South Africa, 883 sexually active women aged 16–22 years were included. Questions were asked about urogenital symptoms and water contact history. Urine samples were tested for S. haematobium ova. A score based on self-reported water contact was calculated and the association with symptoms was explored while adjusting for other genital infections using m…

First morphogenetic analysis of parasite eggs from Schistosomiasis haematobium infected sub-Saharan migrants in Spain and proposal for a new standard…

2021

International audience; Schistosomiasis is a Neglected Tropical Disease caused by trematode species of the genus Schistosoma. Both, autochthonous and imported cases of urogenital schistosomiasis have been described in Europe. The present study focuses on eggs, considered pure S. haematobium by genetic characterisation (intergenic ITS region of the rDNA and cox1 mtDNA). A phenotypic characterisation of S. haematobium eggs was made by morphometric comparison with experimental populations of S. bovis and S. mansoni, to help in the diagnosis of S. haematobium populations infecting sub-Saharan migrants in Spain. Analyses were made by Computer Image Analysis System (CIAS) applied on the basis of …

Mapping 123 million neonatal, infant and child deaths between 2000 and 2017

2019

Since 2000, many countries have achieved considerable success in improving child survival, but localized progress remains unclear. To inform efforts towards United Nations Sustainable Development Goal 3.2—to end preventable child deaths by 2030—we need consistently estimated data at the subnational level regarding child mortality rates and trends. Here we quantified, for the period 2000–2017, the subnational variation in mortality rates and number of deaths of neonates, infants and children under 5 years of age within 99 low- and middle-income countries using a geostatistical survival model. We estimated that 32% of children under 5 in these countries lived in districts that had attained ra…
