Carbapenem-induced β-lactamase-isoform expression trends in Acinetobacter baumannii.

Carbapenem-resistant Acinetobacter baumannii (CRAb) is an urgent bacterial threat to public health, with only a few treatment options and a > 50% fatality rate. Although several resistance mechanisms are understood, it is still impossible to predict which mutations are most likely to occur. Here, we demonstrate that independent samples of Ab, exposed to different carbapenems with escalating concentrations, show concentration- and carbapenem-dependent trends in β-lactamase-isoform expression.

Study of the impact of ClinGen Revisions on ACMG/AMP variant semi-automatic classification for Rare Diseases diagnosis.

With the rapid development of massive sequencing technologies, the analysis of genetic variants for clinical diagnosis has exponentially escalated, particularly in the context of Rare Diseases (RDs). Diagnosing them involves identifying the genetic variants responsible for the underlying pathology development. In 2015, the American College of Medical Genetics (ACMG) established a set of recommendations to assess the evidence associated with each variant, aiming to achieve a standardized five tier classification.

Predictors of Recurrence in Nonmetastatic Appendiceal Epithelial Cancers: An Updated Single-Center Experience Over 25 Years.

Background: Appendiceal epithelial tumors are rare and encompass a broad set of adenocarcinoma histologies, including mucinous (mAC), colonic-type (cAC), and goblet cell (GCA) adenocarcinomas. It has previously been reported that nodal disease predicted recurrence in patients with nonmetastatic appendiceal adenocarcinomas, supporting diagnostic laparoscopy with right hemicolectomy for staging and assessment for risk of recurrence. In this update, we sought to identify predictors of nodal disease on initial diagnostic pathology in nonmetastatic adenocarcinomas.

Methods: Patients with WDPMT identified between August 2007 and December 2020 were followed through January 2023.

Selection of allergen extract for immunotherapy in polysensitized allergic rhinitis patients.

To evaluate the criteria used by allergists in selecting an immunotherapy extract (allergen immunotherapy [AIT]-extract) in rhinitis patients with polysensitization. First, a cross-sectional study was carried out by evaluating different factors that influence the medical choice of AIT-extract. Second, a literature review was performed by evaluating the diagnostic performance of atopy tests.

Efficient Parameterization of Density Functional Tight-Binding for 5-Elements: A Th-O Case Study.

Density functional tight binding (DFTB) models for -element species are challenging to parametrize owing to the large number of adjustable parameters. The explicit optimization of the terms entering the semiempirical DFTB Hamiltonian related to orbitals is crucial to generating a reliable parametrization for -block elements, because they play import roles in bonding interactions. However, since the number of parameters grows quadratically with the number of orbitals, the computational cost for parameter optimization is much more expensive for the -elements than for the main group elements.

Development and Bayesian validation of a competitive inhibition ELISA for detection of antibodies against Brucella abortus in cattle.

Bovine brucellosis is a zoonotic disease caused by Brucella abortus, responsible for abortions in cows. It is endemic in low- and middle-income countries, where the brucellosis control and eradication programs are based on compulsory vaccination, detection of infected cattle through serologic assays, and culling of infected animals at slaughterhouses. The development of high sensitivity and specificity, and low-cost serologic assays guarantee their implementation in countries where the disease is endemic.

Carbapenem-induced β-lactamase-isoform expression trends in .

Unlabelled: Carbapenem-resistant (CRAb) is an urgent bacterial threat to public health, with only a few treatment options and a >50% fatality rate. Although several resistance mechanisms are understood, the appearance of these mutations is generally considered stochastic. Recent reports have, however, begun to challenge this assumption.

Phenotypic and genetic characterization of Africanized colonies with natural tolerance to and contrasting defensive behavior.

Africanized colonies with promising characteristics for beekeeping have been detected in northern Argentina (subtropical climate) and are considered of interest for breeding programs. Integral evaluation of this feral material revealed high colony strength and resistance/tolerance to brood diseases. However, these Africanized honeybees (AHB) also showed variable negative behavioral traits for beekeeping, such as defensiveness, tendency to swarm and avoidance behavior.

Individualized dose of anti-thymocyte globulin based on weight and pre-transplantation lymphocyte counts in pediatric patients: a single center experience.

Anti-thymocyte globulin (ATG) has become a standard in preventing GVHD in related and unrelated donor transplantation, but there is no consensus on the best administration schedule. The PARACHUTE trial reported excellent CD4 immune reconstitution (CD4 IR) using a dosing schedule based on the patient's weight and pre-conditioning absolute lymphocyte count (ALC). In 2015 we introduced the PARACHUTE dosing schedule for pediatric patients at our center.

Influence of physical activity on the prognosis of COPD patients: the HADO.2 score - health, activity, dyspnoea and obstruction.

Objective: The aim of this study was to create a prognostic instrument for COPD with a multidimensional perspective that includes physical activity (PA). The score also included health status, dyspnoea and forced expiratory volume in 1 s (HADO.2 score).

How megadrought causes extensive mortality in a deep-rooted shrub species normally resistant to drought-induced dieback: The role of a biotic mortality agent.

Southern California experienced unprecedented megadrought between 2012 and 2018. During this time, Malosma laurina, a chaparral species normally resilient to single-year intense drought, developed extensive mortality exceeding 60% throughout low-elevation coastal populations of the Santa Monica Mountains. We assessed the physiological mechanisms by which the advent of megadrought predisposed M.

Automated software for counting and measuring Hyalella genus using artificial intelligence.

Amphipods belonging to the Hyalella genus are macroinvertebrates that inhabit aquatic environments. They are of particular interest in areas such as limnology and ecotoxicology, where data on the number of Hyalella individuals and their allometric measurements are used to assess the environmental dynamics of aquatic ecosystems. In this study, we introduce HyACS, a software tool that uses a model developed with the YOLOv3's architecture to detect individuals, and digital image processing techniques to extract morphological metrics of the Hyalella genus.

Older Adult Patients in the Emergency Department: Which Patients should be Selected for a Different Approach?

Background: While multidimensional and interdisciplinary assessment of older adult patients improves their short-term outcomes after evaluation in the emergency department (ED), this assessment is time-consuming and ill-suited for the busy environment. Thus, identifying patients who will benefit from this strategy is challenging. Therefore, this study aimed to identify older adult patients suitable for a different ED approach as well as independent variables associated with poor short-term clinical outcomes.

[Monitoring of anticoagulant treatment with Unfractionated Heparin in pediatrics].

Unlabelled: Unfractionated heparin (UFH) is the most widely used anticoagulant in hospitalized patients. The therapeutic range (TR) was defined in adults according to the prolongation of the activated Partial Thromboplastin Time (aPTT). However, the recommendation is to maintain a therapeutic range with anti-factor Xa assay (antiFXa).

Direct MR arthrography of the hip joint: anterior approach without imaging guidance.

Purpose: The purpose of this study is to describe the anterior injection approach, with anatomical landmark guidance, for direct MR arthrography (dMRA) of the hip joint, and to evaluate the effectiveness in joint distension and the security of the technique.

Material And Methods: Retrospective review of hip dMRAs was conducted on patients with suspected intra-articular pathology from two MR outpatient centers, performed by two radiologists with 25 and 5 years of experience, respectively. The analysis included assessing the presence of intra-articular contrast material (gadolinium-based solution), the number of injections performed, the degree of joint distension, and the degree of contrast extravasation.

Strategies of diaspore dispersal investment in Compositae: the case of the Andean highlands.

Background And Aims: Understanding diaspore morphology and how much a species invests on dispersal appendages is key for improving our knowledge of dispersal in fragmented habitats. We investigate diaspore morphological traits in high-Andean Compositae and their main abiotic and biotic drivers and test whether they play a role in species distribution patterns across the naturally fragmented high-Andean grasslands.

Methods: We collected diaspore trait data for 125 Compositae species across 47 tropical high-Andean summits, focusing on achene length and pappus-to-achene length ratio, with the latter as a proxy of dispersal investment.

Advance Care Planning in Ecuador.

Advance Care Planning is a process by which a patient's health care preferences are established in advance in the event that he or she become temporarily or constantly unable to make decisions for themselves in the future. It is also applied early in emergencies, in intensive care treatment, and after surgery where one's ability to decide is reduced. In Ecuador there is currently no legislation on this subject, however, the National Health Bioethics Commission validated and published the document "Advance Living Will" and as an important advance issued a favorable criterion before the National Assembly for it to be incorporated into the Organic Health Code, the concept, regulations, and the text of Vital Advance Will.

Axillary management in patients with breast cancer and positive axilla at diagnosis. Experience in a Spanish university hospital with a 5-year follow-up.

Background: Axillary lymph node dissection (ALND) was the standard in breast cancer with axillary involvement until recently. Along with the number of metastatic nodes, axillary positivity was considered a main prognostic factor and scientific evidence shows that the administration of radiotherapy on ganglion areas decreases the risk of recurrence even in positive axilla. The objective of this study was to evaluate the axillary treatment in patients with positive axilla at diagnosis, the evolution of them over time, and to assess patient's follow-up with the aim of avoiding the morbidity associated with axillary dissection.
