MONOCYTES MACROPHAGES EXPRESSION OF Ml OR M2 PHENOTYPES IN LATENT TUBERCULOSIS, ACTIVE DISEASES AND UNINFECTED MIGRANTS AND SICILIAN PATIENTS
2016
The high grade ofphenotype plasticity of monocytes macrophages, is resumed in two different cell subsets named M1 or M2. Several studies of microbial infections in vitro and in vivo, showed that, during the early stage of infection, macrophages are polarized toward Ml phenotype that should be protective against pathogen, while during the chronic phase of infection/disease macrophages polarize toward M2 phenotype to avoid damages from a prolonged Ml type activation.Obiettivo: In order to investigate if Mycobacterium tuberculosis infection can drive circulating monocytes toward the expression of Ml or M2 phenotypes, we have analyzed by flow cytometry monocytes obtained from patients with acti…
Depression comorbid with tuberculosis and its impact on health status: cross-sectional analysis of community-based data from 48 low- and middle-incom…
2017
Background Depression in tuberculosis increases the risk for adverse health outcomes. However, little is known about comorbid depression and tuberculosis in the general population. Thus, we assessed the association between depression and tuberculosis, and the decrements in health status associated with this comorbidity in 48 low- and middle-income countries. Methods Cross-sectional, community-based data from the World Health Survey on 242,952 individuals aged ≥ 18 years were analyzed. Based on the World Mental Health Survey version of the Composite International Diagnostic Interview, past 12-month depression was categorized into depressive episode, brief depressive episode, subsyndromal dep…
A model species for agricultural pest genomics: the genome of the Colorado potato beetle, Leptinotarsa decemlineata (Coleoptera: Chrysomelidae)
2018
AbstractThe Colorado potato beetle is one of the most challenging agricultural pests to manage. It has shown a spectacular ability to adapt to a variety of solanaceaeous plants and variable climates during its global invasion, and, notably, to rapidly evolve insecticide resistance. To examine evidence of rapid evolutionary change, and to understand the genetic basis of herbivory and insecticide resistance, we tested for structural and functional genomic changes relative to other arthropod species using genome sequencing, transcriptomics, and community annotation. Two factors that might facilitate rapid evolutionary change include transposable elements, which comprise at least 17% of the gen…
Mycobacterium tuberculosis prosthetic joint infections a case series and literature review
2018
International audience; Objectives - We aimed to characterize diagnosis, management, and outcome of Mycobacterium tuberculosis prosthetic joint infections (PJI).Methods - Cases of M. tuberculosis PJI documented in 7 referral French centers were retrospectively reviewed. Data were collected from medical files on a standardized questionnaire. We performed a literature review using the keywords 'prosthetic joint', and 'tuberculosis'. Results - During years 1997-2016, 13 patients (8 males, 5 females, median age 79 years [range, 60-86]) had documented M. tuberculosis PJI, involving hip (n = 6), knee (n = 6), or shoulder (n = 1). Median time from arthroplasty to diagnosis was 9 years [0.4-20]. Th…
Determinants of patient and health system delay among Italian and foreign-born patients with pulmonary tuberculosis: a multicentre cross-sectional st…
2018
ObjectivesThe aim of this cross-sectional study was to identify key factors associated with patient delay (PD), health system delay (HSD) and total delay (TOTD) in patients with tuberculosis (TB) to inform control programmes.SettingThe study was conducted in four Italian regions in 2014–2016. Data were obtained using a questionnaire including: sociodemographic and lifestyle data, TB comorbidities, patient knowledge and attitudes towards TB, stigma, access to TB care and health-seeking behaviours.ParticipantsPatients’ inclusion criteria were being diagnosed as a new smear positive pulmonary TB case and living in one of the participating Italian regions. Overall, 344 patients from 30 healthca…
Fried potato consumption is associated with elevated mortality: an 8-y longitudinal cohort study
2017
Background: Few studies have assessed the association between potato consumption and mortality. Objective: We investigated whether potato consumption (including fried and unfried potatoes) is associated with increased premature mortality risk in a North American cohort. Design: A longitudinal analysis included 4440 participants aged 45-79 y at baseline with an 8-y follow-up from the Osteoarthritis Initiative cohort study. Potato consumption (including fried and unfried potatoes) was analyzed by using a Block Brief 2000 food-frequency questionnaire and categorized as ≤1 time/mo, 2-3 times/mo, 1 time/wk, 2 times/wk, or ≥3 times/wk. Mortality was ascertained through validated cases of death. T…
Potato Consumption is not Associated with Higher Risk of Mortality: A Longitudinal Study among Southern Italian Older Adults
2018
Objective: The consumption of potatoes is increasing worldwide, but few studies have assessed the association between potato consumption and mortality, particularly in Mediterranean countries. We therefore investigated whether potato consumption is associated with higher risk of death in a large cohort of people living in South Italy. Design: Longitudinal. Setting: Community-dwelling. Measurements: 2,442 participants coming from MICOL and NUTRIHEP studies aged more than 50 years at baseline were followed-up for 11 years. Dietary intake was assessed by means of a Food Frequency Questionnaire. Potato consumption was categorized in quintiles according to their daily consumption (< 3.95, 3.9…
Janus -faced liposomes enhance antimicrobial innate immune response in Mycobacterium tuberculosis infection
2012
We have generated unique asymmetric liposomes with phosphatidylserine (PS) distributed at the outer membrane surface to resemble apoptotic bodies and phosphatidic acid (PA) at the inner layer as a strategy to enhance innate antimycobacterial activity in phagocytes while limiting the inflammatory response. Results show that these apoptotic body-like liposomes carrying PA (ABL/PA) ( i ) are more efficiently internalized by human macrophages than by nonprofessional phagocytes, ( ii ) induce cytosolic Ca 2+ influx, ( iii ) promote Ca 2+ -dependent maturation of phagolysosomes containing Mycobacterium tuberculosis (MTB), ( iv ) induce Ca 2+ -dependent reactive oxygen species (ROS) production, (…
Molecular epidemiology and whole genome sequencing analysis of clinical Mycobacterium bovis from Ghana
2019
[Background]: Bovine tuberculosis (bTB) caused by Mycobacterium bovis is a re-emerging problem in both livestock and humans. The association of some M. bovis strains with hyper-virulence, MDR-TB and disseminated disease makes it imperative to understand the biology of the pathogen.
