Identifying patients with prostate cancer at increased risk for haematuria during anticoagulation for venous thromboembolism.

Background: Haematuria is a common complication in prostate cancer patients receiving anticoagulation for venous thromboembolism (VTE). Early identification of at-risk patients might help to reduce its incidence and severity.

Methods: We used data from the RIETE registry to develop a prognostic score for haematuria during the first year of anticoagulation for VTE.

Risk factors for extended-spectrum beta-lactamase (ESBL)-producing E. coli carriage among children in a food animal-producing region of Ecuador: A repeated measures observational study.

Background: The spread of antibiotic-resistant bacteria may be driven by human-animal-environment interactions, especially in regions with limited restrictions on antibiotic use, widespread food animal production, and free-roaming domestic animals. In this study, we aimed to identify risk factors related to commercial food animal production, small-scale or "backyard" food animal production, domestic animal ownership, and practices related to animal handling, waste disposal, and antibiotic use in Ecuadorian communities.

Methods And Findings: We conducted a repeated measures study from 2018 to 2021 in 7 semirural parishes of Quito, Ecuador to identify determinants of third-generation cephalosporin-resistant E.

Leveraging the COVID-19 pandemic as a natural experiment to assess changes in antibiotic use and antibiotic-resistant E. coli carriage in semi-rural Ecuador.

The coronavirus 2019 (COVID-19) pandemic has had significant impacts on health systems, population dynamics, public health awareness, and antibiotic stewardship, which could affect antibiotic resistant bacteria (ARB) emergence and transmission. In this study, we aimed to compare knowledge, attitudes, and practices (KAP) of antibiotic use and ARB carriage in Ecuadorian communities before versus after the COVID-19 pandemic began. We leveraged data collected for a repeated measures observational study of third-generation cephalosporin-resistant E.

Risk factors for third-generation cephalosporin-resistant and extended-spectrum β-lactamase-producing Escherichia coli carriage in domestic animals of semirural parishes east of Quito, Ecuador.

Extended-spectrum β-lactamase (ESBL)-producing and other antimicrobial resistant (AR) Escherichia coli threaten human and animal health worldwide. This study examined risk factors for domestic animal colonization with ceftriaxone-resistant (CR) and ESBL-producing E. coli in semirural parishes east of Quito, Ecuador, where small-scale food animal production is common.

Influenza A-Associated In-Hospital Mortality in Very Older People: Does Inflammation Also Play a Role?

Background: The aim of the study was to analyze the clinical manifestations and outcome of the oldest old (people aged ≥85 years) who were admitted to the hospital with a confirmed influenza A virus infection in comparison with younger patients and to assess the role of inflammation in the outcome of influenza infection in this population.

Methods: This is an observational prospective study including all adult patients with influenza A virus infection hospitalized in a tertiary teaching hospital in Madrid, in 2 consecutive influenza seasons (2016-17 and 2017-18).

Results: Five hundred nine hospitalized patients with influenza A infection were included, of whom 117 (23%) were older than 85 years (median age: 89.

SARS-CoV-2 infection in cancer patients undergoing active treatment: analysis of clinical features and predictive factors for severe respiratory failure and death.

Aim: Previous studies have suggested a more frequent and severe course of novel coronavirus SARS-CoV-2 infection in cancer patients undergoing active oncologic treatment. Our aim was to describe the characteristics of the disease in this population and to determine predictive factors for poor outcome in terms of severe respiratory distress (acute respiratory distress syndrome [ARDS]) or death.

Patients And Methods: Patients consecutively admitted for SARS-CoV-2 infection were prospectively collected, and retrospective statistical analysis was performed.

Daptomycin Plus Fosfomycin as Salvage Therapy in a Difficult-to-Treat Total Femoral Replacement Infection.

The highly active anti-biofilm combination of daptomycin plus fosfomycin was successfully used in a difficult-to-treat infection of a total femoral replacement caused by multi-drug resistant in a 79-year-old woman. There was no need to remove the orthopedic hardware, and the patient is currently pain free and able to walk.

Impact of functional status on 6-month mortality in elderly patients with acute venous thromboembolism: results from a prospective cohort.

Functional status linked to a poor outcome in a broad spectrum of medical disorders. Barthel Activities of Daily Life Index (BADLI) is one of the most extended tools to quantify functional dependence. Whether BADLI can help to predict outcomes in elderly patients with acute venous thromboembolism (VTE) is unknown.

Comparative void-volume analysis of psychrophilic and mesophilic enzymes: Structural bioinformatics of psychrophilic enzymes reveals sources of core flexibility.

Background: Psychrophiles, cold-adapted organisms, have adapted to live at low temperatures by using a variety of mechanisms. Their enzymes are active at cold temperatures by being structurally more flexible than mesophilic enzymes. Even though, there are some indications of the possible structural mechanisms by which psychrophilic enzymes are catalytic active at cold temperatures, there is not a generalized structural property common to all psychrophilic enzymes.

Enhanced thermal stability achieved without increased conformational rigidity at physiological temperatures: spatial propagation of differential flexibility in rubredoxin hybrids.

The extreme thermal stability of proteins from hyperthermophilic organisms is widely believed to arise from an increased conformational rigidity in the native state. In apparent contrast to this paradigm, both Pyrococcus furiosus (Pf) rubredoxin, the most thermostable protein characterized to date, and its Clostridium pasteurianum (Cp) mesophile homolog undergo a transient conformational opening of their multi-turn segments, which is more favorable in hyperthermophile proteins below room temperature. Substitution of the hyperthermophile multi-turn sequence into the mesophile protein sequence yields a hybrid, (14-33(Pf)) Cp, that exhibits a 12 degrees increase in its reversible thermal unfolding transition midpoint.

Contribution of the multi-turn segment in the reversible thermal stability of hyperthermophile rubredoxin: NMR thermal chemical exchange analysis of sequence hybrids.

Pyrococcus furiosus (Pf) rubredoxin is the most thermostable protein characterized to date. Reflecting the complications arising from irreversible denaturation of this protein, predictions of which structural regions confer differential thermal stability have utilized kinetic stability measurements, hydrogen exchange protection factors, long range hydrogen bond NMR spin couplings, and molecular dynamics simulations, and have primarily implicated the three-stranded beta-sheet and the adjacent metal binding site. Herein, NMR chemical exchange experiments demonstrate reversible two-state unfolding at the thermal transition temperature (T(m)) for hybrids of Pf and the mesophile Clostridium pasteurianum (Cp) rubredoxins which interchange residues 14-33, the so-called multi-turn segment.
