Health and Demographic Characteristics of Patients Attending a Newly-Opened Medical Facility in a Remote Amazonian Community: A Descriptive Study

2018

Peru is a country with wide regional disparities in health. Remote Amazonian communities have high rates of poverty and poor access to health services. There is a lack of data on morbidity and use of health services in the region. We describe a descriptive, cross-sectional study of the demographic characteristics and presenting complaints of attendees to a newly-opened primary care facility in a remote community. This was supplemented by structured interviews of adult attendees to build a picture of sociocultural determinants of health locally, including engagement with traditional forms of medicine. Our study provides novel insights into an under-studied and under-resourced area. We found …

Immune Modulating Effects of NKT Cells in a Physiologically Low Dose Leishmania major Infection Model after αGalCer Analog PBS57 Stimulation

2014

Leishmaniasis is a parasitic infection affecting ∼12 million people worldwide, mostly in developing countries. Treatment options are limited and no effective vaccines exist to date. Natural Killer T (NKT) cells are a conserved innate-like lymphocyte population with immunomodulating effects in various settings. A number of reports state a role of NKT cells in different models of Leishmania infection. Here, we investigated the effect of NKT cells in a physiologically relevant, intradermal low dose infection model. After inoculation of 103 infectious-stage L. major, comparable numbers of skin-immigrating NKT cells in both susceptible BALB/c mice and resistant C57BL/6 mice were noted. Compared …

Tuberculosis among Migrant Populations in Sicily: A Field Report

2021

Background. In the EU, tuberculosis (TB) mainly affects vulnerable people, including migrants. From 2014 to 2017, we have estimated the frequency of both tuberculosis and latent tuberculosis infection (LTBI) among the migrant population hosted in 41 reception centers in western Sicily (ITaCA network). Materials and Methods. All migrants were consecutively recruited for the screening of TB infection with physical examination and TST in 1,020 migrants and with IGRA in the others 2,690. The screening was carried out 4–8 weeks after landing in Sicily. For all migrants with a positive screening test, chest X-ray and smear examination were performed. LTBI was defined by positivity of TST or IGRA …

Malalties tropicals oblidades: determinants del seu estat actual

2015

Les malalties tropicals oblidades són malalties infeccioses lligades a la pobresa, i que afecten als sectors més desafavorits dels països en vies de desenvolupament. S'estima que una sisena part de la població mundial pateix avui en dia les greus conseqüències d'aquestes malalties. Però, malgrat la seua alta prevalença, les malalties tropicals oblidades romanen invisibles per a la majoria de la societat. Així doncs, en aquest treball es pretén determinar el grau de desconeixement i percepció que té el sector universitari d'aquestes malalties a través d'enquestes. Així mateix, també s'ha fet una revisió d'alguns mitjans de comunicació amb l'objectiu d'analitzar el seu grau de cobertura medià…

Fourth case of louse-borne relapsing fever in Young Migrant, Sicily, Italy, December 2015. Mini Review Article

2016

Abstract Objectives Currently louse-borne relapsing fever (LBRF) is primarily found in limited endemic foci in Ethiopia, Somalia and Sudan; no case of imported LBRF has been reported in Europe in the 9 years prior to 2015. The aim of our paper is to describe a new case of imported LBRF detected in Sicily, Italy, and to review all cases reported in migrants arrived in Europe in the last 10 years. Study design Mini review of all published cases of louse-borne relapsing fever in Europe in the last 10 years. Methods A computerized search without language restriction was conducted using PubMed combining the terms ‘(louse-borne relapsing fever or LBRF or recurrentis) and (refugee or Europe or mig…

Geotomus granulosus, a peculiar sehirine-like new species of the subfamily Cydninae (Hemiptera: Heteroptera: Cydnidae) from Burundi

2022

Geotomus granulosus sp. n. is described from Burundi, and is the third burrower bug species recorded hitherto from this country. This burrower bug resembles species of two Sehirinae genera, i.e. Ochetostethus Fieber, 1860 and Ochetostethomorpha Schumacher, 1913, in its dorsal body habitus. However, all its crucial diagnostic characters (the body chaetotaxy, the shape of evaporatoria and the peritreme, the meso- and metathoracic wings venation, and the shape of spermatheca) demonstrate it represents the genus Geotomus Mulsant et Rey, 1866 (subfamily Cydninae, tribe Geotomini sensu lato).

ALLERGENS IN THE PARK AND GARDEN FLORA OF SICILY

2017

The ornamental flora of parks and gardens, as we know, generally includes high proportions of exotics. In Italy it arose from Renaissance on and increasingly enriched up to include a large proportion of exotics native to countries under Mediterranean and temperate climates. Similarly the garden flora of Sicily has a large number of mostly Mediterranean and subtropical exotics. Even if very similar on the whole, these floras differ in some floristic, biological and ecological features. Indeed, several succulent families and genera that are rare or missing in Italy are frequent in Sicily, but plants from temperate regions are almost absent in the island. As regards the allergenic patterns ref…

KOSMOS 2017 Peru Side Experiment: nutrients, phytoplankton abundances, enzyme rates, photophysiology

2022

This data was collected during an short-term incubation experiment in March 2017 that investigated the response of a surface plankton community to upwelling. This experiment was carried in the framework of the SFB754-funded KOSMOS mesocosm study that took place in La Punta, Callao, Peru between February-April 2017. A total of six different treatments were used to disentangle chemical and biological characteristics of deep water that influence surface plankton blooms: 2 different deep water sources with different nutrient concentrations; 3 treatments to distinguish the effects of inorganic nutrients, organic nutrients and deep water microbial populations. Measured variables include inorganic…
