Inhibition of Bacterial and Fungal Biofilm Formation by 675 Extracts from Microalgae and Cyanobacteria
Bacterial biofilms are complex biological systems that are difficult to eradicate at a medical, industrial, or environmental level. Biofilms confer bacteria protection against external factors and antimicrobial treatments. ...
Assessment of In Vitro Cefiderocol Susceptibility and Comparators against an Epidemiologically Diverse Collection of Acinetobacter baumannii Clinical Isolates.
Cefiderocol is a catechol-substituted siderophore cephalosporin combining rapid penetration into the periplasmic space with increased stability against β-lactamases. This study provides additional data on the in vitro ...
High within-host diversity found from direct genotyping on post-mortem tuberculosis specimens in a high-burden setting
Objectives: To characterize the clonal complexity in Mycobacterium tuberculosis (MTB) infections considering factors that help maximize the detection of coexisting strains/variants. Methods: Genotypic analysis by Mycobacterial ...
Effectiveness and cost-effectiveness of Improving clinicians' diagnostic and communication Skills on Antibiotic prescribing Appropriateness in patients with acute Cough in primary care in CATalonia (the ISAAC-CAT study): Study protocol for a cluster randomised controlled trial
Background: Despite their marginal benefit, about 60% of acute lower respiratory tract infections (ALRTIs) are currently treated with antibiotics in Catalonia. This study aims to evaluate the effectiveness and efficiency ...
Growth of Acinetobacter baumannii in pellicle enhanced the expression of potential virulence factors
Background Interestingly, Acinetobacter baumannii presents an enhanced capacity to form biofilms (also named pellicles) at the air-liquid interface as compared to the other Acinetobacter species. This characteristic questions ...
Insight into genetic predisposition to chronic lymphocytic leukemia from integrative epigenomics.
Genome-wide association studies have provided evidence for inherited genetic predisposition to chronic lymphocytic leukemia (CLL). To gain insight into the mechanisms underlying CLL risk we analyze chromatin accessibility, ...
Biological prognostic and therapeutic impact of the epigenome in CLL
Chronic lymphocytic leukemia (CLL) is characterized by widespread alterations in the genetic and epigenetic landscapes which seem to underlie the variable clinical manifestations observed in patients. Over the last decade, ...
Outcomes of corticosteroid therapy in patients with viral community-acquired pneumonia
Aim: The objective of this study was to assess the therapeutic effects of corticosteroids in adult patients hospitalized with viral community-acquired pneumonia. Methods: This is a retrospective analysis of data collected ...
Calodium hepaticum: Household Clustering Transmission and the Finding of a Source of Human Spurious Infection in a Community of the Amazon Region
Background: Calodium hepaticum (syn. Capillaria hepatica) is a worldwide helminth parasite of which several aspects of transmission still remain unclear. In the Amazon region, the mechanism of transmission based on the ...
Quick detection of nonmelanoma skin cancer by histopathology: feasibility and diagnostic accuracy of immediate cutaneous diagnosis
Background: Dermoscopy, diagnostic cytology, confocal microscopy are used to improve diagnostic accuracy. Frozen section techniques have been used to control margins but not for diagnosis. Objectives: We used a new frozen ...
Neuroanatomical substrate of visuospatial and visuoperceptual impairment in Parkinson's disease.
To determine magnetic resonance imaging patterns of gray matter (GM) atrophy underlying visuospatial and visuoperceptual impairment in Parkinson's disease (PD), we applied voxel-based morphometry to 36 nondemented PD ...
Alteracions del control del cicle cel·lular en neoplàsies humanes
Fins fa poc temps, els mecanismes que portaven un grup de cèl·lules de l'organisme a abandonar el comportament ordenat que caracteritza els teixits dels organismes pluricel·lulars i donar origen al càncer eren desconeguts. ...
A novel strategy based on genomics and specific PCR reveals how a multidrug resistant Mycobacterium tuberculosis strain became prevalent in Equatorial Guinea 15 years after its emergence.
OBJECTIVE: Molecular epidemiology techniques in tuberculosis (TB) can identify high-risk strains that are actively transmitted. We aimed to implement a novel strategy to optimize the identification and control of ...
miR-143 Interferes with ERK5 Signaling, and Abrogates Prostate Cancer Progression in Mice
Abstract Background: Micro RNAs are small, non-coding, single-stranded RNAs that negatively regulate gene expression at the post-transcriptional level. Since miR-143 was found to be down-regulated in prostate cancer cells, ...
The prognostic impact of minimal residual disease in patients with chronic lymphocytic leukemia requiring first-line therapy.
A proportion of patients with chronic lymphocytic leukemia achieve a minimal residual disease negative status after therapy. We retrospectively evaluated the impact of minimal residual disease on the outcome of 255 consecutive ...
A low total metabolic tumor volume independently predicts for a longer time to first treatment in initially observed, low tumor burden follicular lymphoma
Watchful waiting is an acceptable management strategy for advanced-stage, low tumor burden (LTB) patients with follicular lymphoma (FL). However, the prediction of how long this treatment-free observation period will last ...
Psychiatric and psychological assessment of Spanish patients with drug-resistant epilepsy and psychogenic nonepileptic seizures (PNES) with no response to previous treatments
Objective: Psychogenic nonepileptic seizures (PNES) are common imitators of epileptic seizures. Refractoriness to antiseizure medication hinders the differential diagnosis between ES and PNES, carrying deleterious consequences ...
EQD2 Analyses of Vaginal Complications in Exclusive Brachytherapy for Postoperative Endometrial Carcinoma
Background: To evaluate whether EQD2(α/β = 3Gy) at 2 cm3 of the most exposed area of the vagina is related to late vaginal toxicity in postoperative endometrial cancer (PEC) patients (p) treated with exclusive brachytherapy ...
Viral epidemic preparedness: a perspective from five clinical microbiology laboratories in Europe
Background: Pandemic preparedness is critical to respond effectively to existing and emerging/new viral pathogens. Important lessons have been learned during the last pandemic at various levels. This revision discusses ...
Lestaurtinib inhibition of the JAK/STAT signaling pathway in Hodgkin lymphoma inhibits proliferation and induces apoptosis
Standard cytotoxic chemotherapy for Hodgkin Lymphoma (HL) has changed little in 30 years; the treatment for patients with relapsed or refractory disease remains challenging and novel agents are under development. JAK/STAT ...
