Background: This report aims to present a novel system for the management of foot lesions in patients with diabetes. It was developed in the diabetic foot unit (DFU) of the Mutua de Terrassa University Hospital (HUMT) by primary care professionals, the Diabetic Foot Clinic (DFC), and during emergency cases treated by our group based on daily activities in patients with neuropathy or neuroischemia. BODY: This system considers five degrees of action based on two fixed variables: presence of infection and lesion depth.

Methods: This was a quasi-experimental before-after study involving patients in the 53-bed Internal Medicine ward in a university hospital in Spain. The preventive measures included hand hygiene, dysphagia detection, head-of-bed elevation, withdrawal of sedatives in the event of confusion, oral care, and sterile or bottled water use.

Objective: To study the presence of SARS-CoV-2 on surfaces (high, medium and low contact) and airs in non-sanitary spaces with high public influx to evaluate the risk of environmental contagion.
Methods: Surfaces and airs were analysed by RT-qPCR to detect the presence of SARS-CoV-2.
Results: 394 surfaces and air samples were obtained from spaces with high public influx such as offices, shopping centres and nursing homes.

is a pathogenic bacterium, ubiquitous in freshwater environments and able to colonise man-made water systems from which it can be transmitted to humans during outbreaks. The prevention of such outbreaks requires a fast, low cost, automated and often portable detection system. In this work, we present a combination of sample concentration, immunoassay detection, and measurement by chronoamperometry.

The methods used for the diagnosis of LD are direct culture of respiratory samples and urinary antigen detection. However, the sensitivity of culture is low, and the urinary antigen test is specific only for L.

During an 8-year period, hot water in a large hospital building was sampled monthly in areas with suitable dimensioning and recirculation and in areas with dead legs and low-use taps. In the former areas, the percentage of Legionella-negative samples was 83.

Despite continuing efforts to maintain water safety, water quality is still affected by deterioration and pollution. Legionella pneumophila colonizes man-made water systems and can infect humans causing Legionnaire's disease (LD), pneumonia.

The characterisation of clinical and environmental isolates using molecular epidemiology techniques provides epidemiological data for a specific geographic region and makes it possible to carry out phylogenetic and population-based analyses.
View Article and Find Full Text PDFLegionella pneumophila is responsible for Legionnaires' disease (LD). Its detection in both environmental and clinical samples is mainly performed by culture plate method which requires up to 10days to obtain results. Nowadays, there are commercial antibodies against this bacterium, but they have not been tested against all subgroups of L.

The low pathogen concentration needed to produce a disease outbreak makes it essential to process large water volumes and use sensitive and specific methods such as immunoassays for its detection. In the present work, we describe the development of a device based on microfiltration membranes to integrate the concentration and the immunodetection of waterborne bacteria.
View Article and Find Full Text PDFMolecular epidemiologic studies of Legionella have shown different molecular types coexisting in the same environment, with only one having the ability to trigger an outbreak. We therefore studied the proteome of isolates of these different molecular types in search of the proteins responsible for infection. In this study, we performed a differential proteomic analysis between patient-related and non-patient-related environmental isolates using two-dimensional difference gel electrophoresis (2D-DIGE) combined with mass spectrometry.

The aim of the study was to analyze the prevalence of MRSA-ST398 colonization in pigs and in pig farmers in an area with a high pig population (Osona, Barcelona province, Catalonia, Spain).
Methods: We performed a cross-sectional prevalence study in Osona (Catalonia, Spain), from June 2014 to June 2015.
Aim: To characterize the genetic diversity of unrelated Legionella pneumophila clinical isolates in Catalonia and compare with other European regions.
Methods: 95 unrelated isolates were analyzed using monoclonal antibodies and sequence-based typing, 1989-2013.
Results: The isolates showed a high diversity (IOD 0.
Aim: To compare the discriminatory power of pulsed-field gel electrophoresis (PFGE) and sequence-based typing (SBT) in Legionella outbreaks for determining the infection source.
Materials & Methods: Twenty-five investigations of Legionnaires' disease were analyzed by PFGE, SBT and Dresden monoclonal antibody.
Results: The results suggested that monoclonal antibody could reduce the number of Legionella isolates to be characterized by molecular methods.
Background: The invasive mosquito Aedes albopictus, with proven vectorial ability to transmit European autochthonous cycles of dengue and chikungunya virus, has currently colonized every coastal department of Eastern Spain. The main objective of the study was to define the epidemiological and clinical characteristics as well as the trends of these two arboviral diseases in a European area heavily colonized by Ae. albopictus.

In vitro culture of microorganisms is the first technique applied for infection diagnosis which is laborious and time consuming. In recent decades, efforts have been focused on the applicability of "Omics" sciences, highlighting the progress provided by proteomic techniques in the field of infectious diseases.

The objectives of this study were to evaluate the changes in IPD incidence and clinical data as well as the trends in Streptococcus pneumoniae serotype distribution in adults during the peak period of the 2009 influenza A H1N1 pandemic (IAP).
Methods: We performed a prospective multicentre study on IPD from week 42 to 48, 2009 in an area of Barcelona (Catalonia, Spain) covering 1,483,781 adult inhabitants.
Background: Hospital-acquired pneumonia (HAP) is one of the leading nosocomial infections and is associated with high morbidity and mortality. Numerous studies on HAP have been performed in intensive care units (ICUs), whereas very few have focused on patients in general wards. This study examined the incidence of, risk factors for, and outcomes of HAP outside the ICU.

However, hyperinfection can occur in patients receiving immunotherapy resulting in high mortality rates. The main objective of this study was to assess the results of a 10-year multicenter surveillance program performed in an area with dense immigration in Barcelona, Spain.
