Non-HLA Antibodies and the Risk of Antibody-mediated Rejection without Donor-specific Anti-HLA Antibodies After Lung Transplantation.

Background: Antibody-mediated rejection (ABMR) has become one of the leading causes of chronic lung graft dysfunction. However, in lung transplantation, this entity is sometimes difficult and controversial to diagnose. It is mainly caused by the appearance of donor-specific anti-human leukocyte antigen (HLA) antibodies (DSA), although there are situations with C4d deposits in biopsy in the absence of circulating DSA.

Clinical characteristics and risk factors for the acquisition of an enteric infection by Aeromonas spp. in patients with digestive or nephrological diseases.

The role of aeromonads as contributors to gastrointestinal pathology remains controversial. The aim of this study was to analyse the clinical characteristics and risk factors for the acquisition of an enteric infection by Aeromonas spp. in patients with digestive or nephrological diseases.

Basic Science and Pathogenesis.

Background: Preclinical Alzheimer's disease may be linked to impaired cerebral amyloid clearance. We aim to obtain dynamic parameters of cortical and ventricular clearance of C-PIB and compare them with CSF amyloid values in a population of healthy volunteers.

Clinical Manifestations.

Background: Neuropsychological performance guides diagnostic and therapeutic decision-making on Alzheimer's disease (AD) and related disorders. Despite broad recognition that amyloid-beta (Aβ) impacts cognition during preclinical AD, the added value of Aβ-negative norms remains uncertain. Furthermore, normative modeling is constrained by limitations inherent to traditional methods.

Treatment patterns and outcomes in secondary acute myeloid leukemia arising after hypomethylating agents: PETHEMA registry study.

Background: Patients with secondary acute myeloid leukemia who previously received hypomethylating agents for prior myeloid neoplasms (HMA-sAML) face a dismal prognosis.

Methods: The authors analyze the characteristics, therapeutic approaches, and outcomes of patients with HMA-sAML from the Programa Español para el Tratamiento de Hemopatías Malignas (PETHEMA) registry.

Results: A total of 479 patients were included, mostly from prior myelodysplastic syndrome (84%).

Hemodynamic Management guided by the Hypotension Prediction Index in Abdominal Surgery: A Multicenter Randomized Clinical Trial.

Background: Postoperative acute kidney injury (AKI) after major abdominal surgery leads to poor outcomes. The Hypotension Prediction Index (HPI) may aid in managing intraoperative hemodynamic instability. This study assessed if HPI-guided therapy reduces moderate-to-severe AKI incidence in moderate-to-high-risk elective abdominal surgery patients.

Ileal Predominance in Crohn's Disease Is Associated With Increased Intestinal Surgery and Biological Therapy Use, With Lower Treatment Persistence.

Introduction: Crohn's disease (CD) varies by location, potentially affecting therapy efficacy and surgery risk, although research on this topic is conflicting. This study aims to investigate the independent association between CD location and therapeutic patterns.

Methods: We analyzed patients with CD diagnosed from January 2005 to May 2023 registered in the nationwide ENEIDA registry.

Rationale and design of the beta-blockers in tako-tsubo syndrome study: a randomized clinical trial (β-Tako).

Unlabelled: Introduction y objectives: Tako-tsubo syndrome (TTS) is a cardiac condition that mimics acute coronary syndrome, characterized by transient left ventricular dysfunction in the absence of culprit coronary artery stenosis. Although its etiology remains unknown, reversible microvascular dysfunction secondary to an adrenergic surge is thought to play a role. Treatment is empirical, although most patients receive beta-blockers (BB) in clinical practice.

Elastic static power, its correlation with acute respiratory distress syndrome severity: A Bayesian post-hoc analysis of the Mechanical Power Day cross-sectional trial.

Objective: The relationship between different power equations and the severity of acute respiratory distress syndrome (ARDS) remains unclear. This study aimed to evaluate various power equations: total mechanical power, total elastic power (comprising elastic static and elastic dynamic power), and resistive power, in a cohort of mechanically ventilated patients with and without ARDS. Bayesian analysis was employed to refine estimates and quantify uncertainty by incorporating a priori distributions.

Is Bone Marrow Trephine Biopsy Necessary in Multiple Myeloma Patients at Diagnosis?

Multiple myeloma (MM) diagnosis requires ≥10% plasma cell (PC) infiltration in the bone marrow (BM), detected by bone marrow aspiration (BMA) or biopsy (BMB). We evaluated the concordance of these 2 techniques in 189 patients. In 43 cases (23%), the techniques were discordant, 10 due to poor sample quality.

Cross-cultural adaptation, reliability, validity and responsiveness of the hand assessment tool (HAT-Sp) in Spain.

Purpose: The HAT is a questionnaire designed to measure activity limitations in patients with hand and wrist injuries, without assistance. This study aimed to translate, culturally adapt, and validate the psychometric properties of the HAT-validity, reliability, and responsiveness-for different hand conditions in Spain.

Methods: Cultural adaptation followed recommendations from the American Academy of Orthopaedic Surgeons (AAOS).

Validation of a hand-held ultrasound device in the evaluation of aortic stenosis.

Hand-held ultrasound devices (HHUD) are increasingly used in routine clinical practice, though they lacked continuous (CW) Doppler capability until recent times. There is limited evidence on the utility of HHUD in assessing aortic stenosis (AS) in real-world settings. Our goal was to validate a new HHUD with CW Doppler assessing AS hemodynamic severity.

The role of rapid multiplex molecular syndromic panels in the clinical management of infections in critically ill patients: an experts-opinion document.

Rapid multiplex molecular syndromic panels (RMMSP) (3 or more pathogens and time-to-results < 6 h) allow simultaneous detection of multiple pathogens and genotypic resistance markers. Their implementation has revolutionized the clinical landscape by significantly enhancing diagnostic accuracy and reducing time-to-results in different critical conditions. The current revision is a comprehensive but not systematic review of the literature.

Mortality predictors and definition proposal for complicated coagulase-negative Staphylococcus bacteremia. A multicenter prospective cohort study.

Objective: To explore a definition for complicated coagulase-negative staphylococci bloodstream infections (CoNS BSI), and to identify predictors for mortality.

In-depth mass-spectrometry reveals phospho-RAB12 as a blood biomarker of G2019S LRRK2-driven Parkinson's disease.

Leucine-rich repeat kinase 2 (LRRK2) inhibition is a promising disease-modifying therapy for LRRK2-associated Parkinson's disease (L2PD) and idiopathic PD (iPD). However, pharmaco-dynamic readouts and progression biomarkers for clinical trials aiming for disease modification are insufficient since no endogenous marker reflecting enhanced kinase activity of the most common LRRK2 G2019S mutation has been reported yet in L2PD patients. Employing phospho-/proteomic analyses we assessed the impact that LRRK2 activating mutations had in peripheral blood mononuclear cells (PBMCs) from a LRRK2 clinical cohort from Spain (n=174).

Longitudinal trajectory of plasma p-tau217 in cognitively unimpaired subjects.

Background: The advent of Alzheimer's disease-modifying drugs requires accurate biological diagnosis to identify candidates for these therapies. So far, the most promising single plasma biomarker is phosphorylated tau at threonine 217 (p-tau217). To understand its biological features, it is essential to know its longitudinal trajectory and factors influencing it in cognitively unimpaired subjects with no brain pathology.

Carvedilol vs. propranolol for the prevention of decompensation and mortality in patients with compensated and decompensated cirrhosis.

Background And Aims: Data on the effectiveness of classical non-selective beta-blockers (cNSBB, i.e., propranolol and nadolol) versus carvedilol in patients with cirrhosis are scarce.
