José Moreira, Clarisse S Bressan, Patricia Brasil, Andre M Siqueira
BACKGROUND: The causes of acute febrile illness (AFI) in Latin America (LA) are diverse and its complexity increase as the proportion of fever due to malaria decreases as control and new pathogens emerge in the region. In this context, it is important to shed light over the gaps on the epidemiological characteristics and the geographic range for many AFI aetiologies. AIMS: To review studies on community-acquired fever etiology other than malaria in LA, and to highlight knowledge gaps and challenges needing further investigation...

Visual inspection with acetic acid (VIA) is an effective, affordable and simple test for cervical cancer screening in resource-poor settings. But considerable expertise is needed to differentiate cancerous lesions from normal lesions, which is lacking in developing countries. Many studies have attempted automation of cervical cancer detection from cervix images acquired during the VIA process. These studies used images acquired through colposcopy or cervicography. However, colposcopy is expensive and hence is not feasible as a screening tool in resource-poor settings...

BACKGROUND: Multimodal interventions are effective in increasing hand hygiene (HH) compliance amongst healthcare workers, but it is not known whether such interventions are cost-effective outside high-income countries. AIM: To evaluate the cost-effectiveness of multimodal hospital interventions to improve hand hygiene (HH) compliance in a middle-income country. METHOD: We adopted a conservative approach by developing a model to determine whether reductions in Methicillin-resistant Staphylococcus aureus bloodstream infections (MRSA-BSI) alone would make HH interventions cost-effective in intensive care units (ICUs)...

BACKGROUND: Reconstruction of the stage II adult-acquired flatfoot deformity (AAFD) often requires the use of multiple osteotomies and soft tissue procedures that may not heal well in older patients. The purpose of our study was to determine whether patients older than 65 years with stage II AAFD had inferior clinical outcomes or an increased number of subsequent surgical procedures after flatfoot reconstruction when compared with younger patients. METHODS: One-hundred forty consecutive feet (70 right, 70 left) with stage II AAFD in 137 patients were divided into 3 groups based on age: younger than 45 years (young; n = 21), 45 to 65 years (middle-aged; n = 87), and 65 years and older (older; n = 32)...

Acinetobacter baumannii is undoubtedly one of the most clinically significant pathogens. The multidrug resistance and virulence potential of A. baumannii are responsible for hospital-acquired nosocomial infections. Unlike numerous investigations on the drug-resistant epidemiology of A. baumanni , virulence molecular epidemiology is less studied. Here, we collected 88 A. baumannii clinical isolates, tested their antimicrobial susceptibility to 10 commonly used antibiotics and analyzed the distribution of 9 selected virulence-associated genes, aims to investigate the primary characteristics of the virulence-associated genes that exist in clinically multidrug resistant (MDR) and non-MDR isolates of A...

Pseudomonas aeruginosa is one of the most important causes of infection in the intensive care unit. It is intrinsically resistant to many antibiotics and easily acquires additional resistance genes via horizontal gene transfer of mobile genetic elements. In the present study, 1,528 P. aeruginosa isolates, obtained from a Dutch national surveillance program between the years 1998 and 2011, were analyzed for the presence of Extended Spectrum β-Lactamase (ESBL) genes blaCTX-M , blaSHV , blaTEM , blaBEL , blaPER , blaVEB , blaOXA-10 and metallo-β-Lactamase (MBL) genes blaIMP , blaVIM and blaNDM ...

Broad-spectrum antibiotics are widely used in patients on intensive care units (ICU), many of which develop hospital-acquired infections with Pseudomonas aeruginosa. Although preceding antimicrobial therapy is known as a major risk factor for P. aeruginosa-induced pneumonia, the underlying mechanisms remain incompletely understood. Here we demonstrate that depletion of the resident microbiota by broad-spectrum antibiotic treatment inhibited TLR-dependent production of a proliferation inducing ligand (APRIL), resulting in a secondary IgA deficiency in the lung in mice and human ICU patients...

The microbial etiology and source of sepsis influence the inflammatory response. Therefore, the plasma levels of cytokines (IL-6, IL-8, and IL-10), chemokines (CCL2/MCP-1, MIP-1 β ), heparin-binding protein (HBP), soluble CD14 (sCD14), and cortisol were analyzed in blood from septic patients obtained during the first 96 hours of intensive care unit hospitalization. The etiology was established in 56 out of a total of 62 patients enrolled in the study. Plasma concentrations of MCP-1, sCD14, IL-6, and IL-10 were significantly higher in patients with community-acquired pneumonia (CAP; n = 10) and infective endocarditis (IE; n = 11) compared to those with bacterial meningitis (BM; n = 18)...

BACKGROUND: Data sharing has been a big challenge in biomedical informatics because of privacy concerns. Contextual embedding models have demonstrated a very strong representative capability to describe medical concepts (and their context), and they have shown promise as an alternative way to support deep-learning applications without the need to disclose original data. However, contextual embedding models acquired from individual hospitals cannot be directly combined because their embedding spaces are different, and naive pooling renders combined embeddings useless...

Clostridium difficile infection (CDI) symptoms range from diarrhea to severe toxic megacolon and even death. Due to its rapid acquisition of resistance, C. difficile is listed as an urgent antibiotic-resistant threat, and has surpassed methicillin-resistant Staphylococcus aureus (MRSA) as the most common hospital-acquired infections in the USA. To combat the pathogen, the new structural class of pseudo peptides that exhibit antimicrobial activities could play an important role. Herein, we report that bis-cyclic guanidine compounds that exhibit potent antibacterial activity against C...
