Descriptive epidemiology of nasal carriage of Staphylococcus aureus and methicillin-resistant Staphylococcus aureus among patients admitted to two he…
2014
Aim: To evaluate nasal carriage rate and variables associated with Staphylococcus aureus and methicillin-resistant Staphylococcus aureus (MRSA) in patients admitted in two healthcare facilities. Results: S. aureus was isolated from 159 (26%) of the enrolled patients. Methicillin-susceptible S. aureus was isolated from 150 (24.5%) patients, and MRSA was isolated from 9 (1.5%). Cancer and previous hospitalization were associated with a significantly higher frequency of nasal S. aureus carriage among the patients admitted to the general hospital and the nephrology department, respectively. MRSA isolates were heterogeneous with respect to their staphylococcal cassette chromosome mec element (SC…
One Health Approach to Zoonotic Parasites: Molecular Detection of Intestinal Protozoans in an Urban Population of Norway Rats, Rattus norvegicus, in …
2021
Rattus norvegicus, the brown or Norway rat, is the most abundant mammal after humans in urban areas, where they live in close proximity to people. Among rodent-borne diseases, the reservoir role of Norway rats of zoonotic parasites in cities has practically been ignored. Considering the parasitic diseases in the One Health approach, we intended to identify and quantify the zoonotic intestinal protozoans (ZIP) in an urban population of R. norvegicus in the city of Barcelona, Spain. We studied the presence of ZIP in 100 rats trapped in parks (n = 15) as well as in the city’s sewage system (n = 85) in the winter of 2016/17. The protozoans were molecularly identified by means of a multiplex PCR…
Misidentification ofDiphyllobothriumSpecies Related to Global Fish Trade, Europe
2014
To the Editor: Diphyllobothriosis, infection by tapeworms of the genus Diphyllobothrium (Cestoda: Diphyllobothriidea) (1), is a well-known disease of humans. In Europe, infections caused by 3 species of Diphyllobothrium have recently been reported in humans: D. latum is considered to be the principal species infecting persons in Europe (1); 4 cases of D. dendriticum infection and 6 cases of D. nihonkaiense infection have also been reported (2,3). Except for those caused by D. latum, which is autochthonous in northeastern Europe and subalpine lakes, most of the cases in Europe have been imported or caused by consumption of fish imported from areas to which the parasites are endemic (1,3,4). …
Multiple reassortment and interspecies transmission events contribute to the diversity of feline, canine and feline/canine-like human group A rotavir…
2011
Abstract RNA–RNA hybridization assays and complete genome sequence analyses have shown that feline rotavirus (FRV) and canine rotavirus (CRV) strains display at least two distinct genotype constellations (genogroups), represented by the FRV strain RVA/Cat-tc/AUS/Cat97/1984/G3P[3] and the human rotavirus (HRV) strain RVA/Human-tc/JPN/AU-1/1982/G3P3[9], respectively. G3P[3] and G3P[9] strains have been detected sporadically in humans. The complete genomes of two CRV strains (RVA/Dog-tc/ITA/RV198-95/1995/G3P[3] and RVA/Dog-tc/ITA/RV52-96/1996/G3P[3]) and an unusual HRV strain (RVA/Human-tc/ITA/PA260-97/1997/G3P[3]) were determined to further elucidate the complex relationships among FRV, CRV a…
Extraction, Structural Characterisation, and Immunomodulatory Properties of Edible Amanita hemibapha subspecies javanica (Corner and Bas) Mucilage Po…
2021
This research aimed to extract mucilage polysaccharides (MP) from Amanita hemibapha subspecies javanica (Corner and Bas), and further fractionate them using anion-exchange chromatography, yielding two fractions (MPF1 and MPF2). The crude extract, and fractions mainly consisted of carbohydrates (83.5–93.2%) with minor amounts of proteins (5.40–7.20%), and sulphates (1.40–9.30%). Determination of the monosaccharide composition revealed that glucose was the major unit, followed by galactose, mannose, rhamnose, and arabinose. The average molecular weight (MW) of the crude extract and fractions was in the range 104.0–479.4 × 103 g/mol. Interestingly, the crude extract, and fractions did not caus…
Familial Trichostrongylus Infection Misdiagnosed as Acute Fascioliasis
2015
To the Editor: Human fascioliasis, infection with Fasciola spp. flukes, is highly pathogenic in both acute and chronic phases and can result in death (1). This disease has been recently emerging, in part linked to climate and global changes (2). Human Fasciola infection has been reported in 5 continents and is related to the disease’s wide spread in livestock. Guilan Province in northern Iran is a fascioliasis-endemic area where the largest human epidemics have occurred, together affecting ≈15,000 persons (3). In 2014, 3 sisters (ages 35, 33, and 38) and their 41-year-old brother (patients 1–4, respectively) sought medical care at the same time, all with a 3-week history of symptoms. The pa…
The socio-ecology of zoonotic infections
2011
The resurgence of infectious diseases of zoonotic origin observed in recent years imposes a major morbidity/mortality burden worldwide, and also a major economic burden that extends beyond pure medical costs. The resurgence and epidemiology of zoonoses are complex and dynamic, being influenced by varying parameters that can roughly be categorized as human-related, pathogen-related, and climate/environment-related; however, there is significant interplay between these factors. Human-related factors include modern life trends such as ecotourism, increased exposure through hunting or pet owning, and culinary habits, industrialization sequelae such as farming/food chain intensification, globali…
Role of D-Mannose in the Prevention of Recurrent Uncomplicated Cystitis: State of the Art and Future Perspectives
2021
Background: Urinary tract infections (UTI) are highly frequent in women, with a significant impact on healthcare resources. Although antibiotics still represent the standard treatment to manage recurrent UTI (rUTI), D-mannose, an inert monosaccharide that is metabolized and excreted in urine and acts by inhibiting bacterial adhesion to the urothelium, represents a promising nonantibiotic prevention strategy. The aim of this narrative review is to critically analyze clinical studies reporting data concerning the efficacy and safety of D-mannose in the management of rUTIs. Methods: A non-systematic literature search, using the Pubmed, EMBASE, Scopus, Web of science, Cochrane Central Register …
MFCC-based Recurrent Neural Network for automatic clinical depression recognition and assessment from speech
2022
Abstract Clinical depression or Major Depressive Disorder (MDD) is a common and serious medical illness. In this paper, a deep Recurrent Neural Network-based framework is presented to detect depression and to predict its severity level from speech. Low-level and high-level audio features are extracted from audio recordings to predict the 24 scores of the Patient Health Questionnaire and the binary class of depression diagnosis. To overcome the problem of the small size of Speech Depression Recognition (SDR) datasets, expanding training labels and transferred features are considered. The proposed approach outperforms the state-of-art approaches on the DAIC-WOZ database with an overall accura…
Probing in cell protein structural changes with time-resolved X-ray scattering
2012
International audience; Investigating protein structural changes inside the cell is a major goal in molecular biology. Here we show that time-resolved wide-angle X-ray scattering is a valuable tool for this purpose. Hemoglobin has been chosen as a model system and its tertiary and quaternary conformational changes following laser flash-photolysis have been tracked in intact red blood cells with nanosecond time resolution.
