Alu insertion polymorphisms in the African Sahel and the origin of Fulani pastoralists.
2017
The origin of Western African pastoralism, represented today by the Fulani nomads, has been a highly debated issue for the past decades, and has not yet been conclusively resolved.This study focused on Alu polymorphisms in sedentary and nomadic populations across the African Sahel to investigate patterns of diversity that can complement the existing results and contribute to resolving issues concerning the origin of West African pastoralism.A new dataset of 21 Alu biallelic markers covering a substantial part of the African Sahel has been analysed jointly with several published North African populations.Interestingly, with regard to Alu variation, the relationship of Fulani pastoralists to …
Genomic Analysis and Lineage Identification of SARS-CoV-2 Strains in Migrants Accessing Europe Through the Libyan Route
2021
Many African countries, representing the origin of the majority of refugees, asylum-seekers, and other migrants, toward regions bordering on the Mediterranean area, are experiencing sustained local transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Sicily is one of the main entry gates of migrants crossing into Europe. We conducted a pilot study, based on the full-genome sequencing of SARS-CoV-2 strains isolated from migrants coming to Sicily by crossing the Mediterranean Sea, with the aim to investigate the viral genome polymorphism and to describe their genetic variations and the phylogenetic relationships. On June 21, a nongovernmental organization vessel rescu…
Seabird migration strategies: Flight budgets, diel activity patterns and lunar influence
2021
Every year, billions of birds undertake extensive migrations between breeding and nonbreeding areas, facing challenges that require behavioural adjustments, particularly to flight timing and duration. Such adjustments in daily activity patterns and the influence of extrinsic factors (e.g., environmental conditions, moonlight) have received much more research attention in terrestrial than marine migrants. Taking advantage of the widespread deployment in recent decades of combined light-level geolocator-immersion loggers, we investigated diel organisation and influence of the moon on flight activities during the non-breeding season of 21 migrant seabird species from a wide taxonomic range (6 …
The genetic prehistory of the Baltic Sea region
2018
Correction: Nature communications 9 (2018), art. no. 1494 doi:10.1038/s41467-018-03872-y While the series of events that shaped the transition between foraging societies and food producers are well described for Central and Southern Europe, genetic evidence from Northern Europe surrounding the Baltic Sea is still sparse. Here, we report genome-wide DNA data from 38 ancient North Europeans ranging from similar to 9500 to 2200 years before present. Our analysis provides genetic evidence that hunter-gatherers settled Scandinavia via two routes. We reveal that the first Scandinavian farmers derive their ancestry from Anatolia 1000 years earlier than previously demonstrated. The range of Mesolit…
Evaluation of HIV transmission clusters among natives and foreigners living in Italy
2020
We aimed at evaluating the characteristics of HIV-1 molecular transmission clusters (MTCs) among natives and migrants living in Italy, diagnosed between 1998 and 2018. Phylogenetic analyses were performed on HIV-1 polymerase (pol) sequences to characterise subtypes and identify MTCs, divided into small (SMTCs, 2&ndash
Trend in rifampicin-, multidrug- and extensively drug-resistant tuberculosis in Italy, 2009-2016
2018
In Italy, rifampicin-resistant and MDR-TB were high in foreign-born persons, but decreased from 2009 to 2016

ELF and migrant categorization at family clinics in Finland
2019
Artikkelin tavoite on selvittää, miten neuvolan terveydenhoitajat käyttävät puheessaan kieltä, erityisesti englannin kieltä, ei-suomea-puhuvien asiakkaidensa kategorisointiin. Tutkimuksessa hyödynnetään jäsenkategoria-analyysiä (Schegloff, Emanuel A. 2007. A tutorial on membership categorization. Journal of Pragmatics 39(3). 462–482) osoittamaan, miten englannin kielen osaaminen maahanmuuttostatuksen ja syntyperäisen englannin puhujan normin ohella näytti olevan määräävin tekijä siinä, miten terveydenhoitajat kategorisoivat siirtolaistaustaisia asiakkaitaan. Tutkimustulokset osoittavat kuinka vahvasti jäsenkategoriapohjainen luokittelu näkyy institutionaalisessa päätöksenteossa, ja ne koros…
„Wir wussten, dass es schwierig wird, doch damit haben wir nicht gerechnet!“ Erfahrungen beim Studieneinschluss von Krebspatient*innen mit Migrations…
2021
Zusammenfassung Hintergrund Der Prozess des Studieneinschlusses von Teilnehmenden ist ein wichtiger Bestandteil und oftmals aufwendiger Arbeitsschritt in wissenschaftlichen Forschungsprojekten. Aufgrund unterschiedlicher finanzieller, organisatorischer und ethischer Rahmenbedingungen stellt die fristgerechte Gewinnung von Teilnehmenden haufig eine Herausforderung dar. In diesem Beitrag berichten wir uber unsere Erfahrungen hinsichtlich des Studieneinschlusses, die wir im Projekt „Psychoonkologische Versorgung von Krebspatienten mit Migrationshintergrund – eine Mixed-Methods-Studie“ (POM) gemacht haben. Methode Die Gewinnung von Teilnehmenden erfolgte uber ambulante hamato-onkologische Schwe…
