Smoothed Particle Hydrodynamics for free-surface and multiphase flows: a review.

The Smoothed Particle Hydrodynamics (SPH) method is expanding and applied to more and more fields, particularly in engineering. The majority of current SPH developments deal with free-surface and multiphase flows, especially for situations where geometrically complex interface configurations are involved. The present review article covers the last 25 years of development of the method to simulate such flows, discussing the related specific features of the method.

Endocrinologic Dysfunctions and Neuropsychiatric Sequelae in Pediatric Patients With a History of Central Nervous System Infection (ENDLESS): A Prospective Monocentric Study.

Introduction: Central nervous system (CNS) infections represent some of the most critical pediatric health challenges, characterized by high mortality rates and a notable risk of long-term complications. Despite their significance, standardized guidelines for endocrinological follow-up of CNS infection survivors are lacking, leading to reliance on the expertise of individual centers and clinicians.

Materials And Methods: Prospective monocentric observational study conducted at the Fondazione Policlinico Universitario Agostino Gemelli in Rome, Italy.

Exploring Psychedelics Pharmacology: A Scoping Review Charting the Course of Psilocybin Pharmacokinetics.

Objectives: This scoping review aimed to synthesize the existing data about psilocybin pharmacokinetics to learn what has been described regarding body disposition and safety when psilocybin was used in controlled research settings.

Methods: We performed a scoping literature review following the framework proposed by the JBI manual for evidence synthesis. Controlled clinical trials reporting pharmacokinetic data of psilocybin were considered appropriate for inclusion.

Tropical forest clearance impacts biodiversity and function, whereas logging changes structure.

The impacts of degradation and deforestation on tropical forests are poorly understood, particularly at landscape scales. We present an extensive ecosystem analysis of the impacts of logging and conversion of tropical forest to oil palm from a large-scale study in Borneo, synthesizing responses from 82 variables categorized into four ecological levels spanning a broad suite of ecosystem properties: (i) structure and environment, (ii) species traits, (iii) biodiversity, and (iv) ecosystem functions. Responses were highly heterogeneous and often complex and nonlinear.

Clinical control in COPD and therapeutic implications: The EPOCONSUL audit.

Objective: This study aimed to evaluate clinical control in chronic obstructive pulmonary disease (COPD), the consequences in terms of treatment decisions, and their potentially associated factors during follow-up of patients in real-life clinical practice.

Methods: EPOCONSUL 2021 is a cross-sectional audit that evaluated the outpatient care provided to patients with a diagnosis of COPD in respiratory clinics in Spain and multivariable logistic regression models to assess the relationships between clinical control and clinical inertia.

Results: 4225 patients from 45 hospitals in Spain were audited.

Sociodemographic, behavioral, and clinical risk factors associated with cervical dysplasia: A case-control study.

Introduction: Cervical dysplasia is a precursor lesion of cervical cancer, one of the leading causes of morbidity and mortality in women, especially in developing countries. This study aimed to identify the risk factors associated with the development of cervical dysplasia in women treated at the Santa María del Socorro Hospital in Ica, Peru, between 2017 and 2019.

Methods: An observational case-control study was conducted with 92 cases of women with confirmed high-grade intraepithelial lesion and 184 controls with consecutive negative results in Pap smears.

Factors associated with asthma symptoms in Colombian subpopulations aged 1 to 17 and 18 to 59: Secondary analysis of the study "Prevalence of asthma and other allergic diseases in Colombia 2009-2010".

Background: Asthma, a chronic inflammatory lung disease, is one of the leading causes of disability, demands on health resources, and poor quality of life. It is necessary to identify asthma-related risk factors to reduce the presence and development of symptoms.

Objective: This study aimed to explore the association of multiple possible factors with asthma symptoms in two subpopulations, children, adolescents, and adults, in six cities in Colombia.

Anaphylaxis due to green beans (): a new phenotype?

Background: Anaphylaxis is a severe allergic reaction with increasing incidence in Europe. It is often caused by food, insect venom, and drugs. White, red, and green beans () are legumes of the family consumed worldwide.

Vitamin D as an add-on therapy to phosphodiesterase-5 inhibitor in experimental pulmonary arterial hypertension.

Severe vitamin D (vitD) deficiency is a very common condition in patients with pulmonary arterial hypertension (PAH) and it is predictor of poor prognosis. There is emerging evidence suggesting a connection between the insufficient response to phosphodiesterase-5 inhibitors (PDE5i) and vitD deficiency in patients with PAH. In the present translational study, vitD deficiency was induced in Wistar rats by exposure to vitD free diet for 5 weeks and followed by Su5416 administration and hypoxia (10%) for 3 weeks, a standard experimental model of PAH.

Chlamydia in farms located in the Argentine-Brazilian-Paraguay tri-border.

Chlamydias are zoonotic pathogens, broadly present in several bird species and responsible for economic losses in animal production. Our study focused on assessing the prevalence of Chlamydial species posing zoonotic risks in farm animals within the highly biodiverse Argentine, Brazil, and Paraguay tri-border area, characterized by significant human interaction. We surveyed nine farms in an area and nasally swabbed a total of 62 animals, that included cattle, horses and pigs.

The influence of prolonged aerobic exercise on cardiac, muscular, and renal biomarkers in trained individuals with obesity.

Purpose: The aim of this study was to investigate the influence of prolonged aerobic exercise on cardiac, muscular and renal inflammatory markers in a group of trained obese men.

Methods: Seventeen men (aged 40 ± 6 years; body mass index [BMI] 31.3 ± 2.

Performance of Noninvasive Tests for Metabolic Dysfunction-Associated Steatohepatitis and Liver Fibrosis Resolution after Bariatric Surgery.

Background: Noninvasive tests (NITs) to monitor metabolic dysfunction-associated steatohepatitis (MASH) progression and response to interventions are needed because of the risks of liver biopsy. A monocytes-based diagnostic test using perilipin-2 (PLIN2) and Ras-related protein-14 (RAB14) predict the severity of MASH and fibrosis. Here we compared the performances of PLIN2 and RAB14 with cytokeratin-18 (CK18) assessed by Ella™ or M65 ELISA in predicting MASH and fibrosis resolution following bariatric surgery in a longitudinal and histologically characterized cohort of individuals with obesity.

Mechanism of syncope: role of ambulatory blood pressure monitoring and cardiovascular autonomic function assessment.

Background And Aims: Identifying the haemodynamic mechanism of autonomic syncope is the essential pre-requisite for effective and personalized therapy aimed at preventing recurrences. The present study assessed the diagnostic efficacy of a two-step assessment.

Methods: Multicentre prospective, cross-sectional, observational study.

Triple Combination of MEK, BET, and CDK Inhibitors Significantly Reduces Human Malignant Peripheral Nerve Sheath Tumors in Mouse Models.

Purpose: Malignant peripheral nerve sheath tumor (MPNST) is an aggressive soft tissue sarcoma that develops sporadically or in Neurofibromatosis type 1 patients. Its development is marked by the inactivation of specific tumor suppressor genes (TSGs): NF1, CDKN2A and SUZ12EED (Polycomb Repressor Complex 2). Each TSG loss can be targeted by particular drug inhibitors and we aimed to systematically combine these inhibitors, guided by TSG inactivation status, to test their precision medicine potential for MPNSTs.

Preservation of Cardiac Xenografts in a Model of Infant Human Cardiac Transplantation.

Introduction: There is no standard protocol for management of organ preservation for orthotopic, life-sustaining cardiac xenotransplantation, particularly for hearts from pediatric sized donors. Standard techniques and solutions successful in human allotransplantation are not viable. We theorized that a solution commonly used in reparative cardiac surgery in human children would suffice by exploiting the advantages inherent to xenotransplantation, namely the ability to reduce organ ischemic times by co-locating the donor and recipient.

Biomarkers.

Background: Beyond dementia syndromes, cognitive symptoms are highly prevalent in Parkinson's disease (PD), often manifesting as mild cognitive impairment (MCI). Yet, their detection and characterization remain suboptimal because standard approaches rely on subjective impressions derived from lengthy, univariate tests. Here we introduce a novel approach to detect cognitive symptom severity and identify MCI in PD using fully automated word property analyses on brief verbal fluency tasks.

Biomarkers.

Background: Chronic exposition to stressor factors has been postulated as a cause of structural changes in the brain in the context of dementia. One of these changes can be the fiber integrity loss, that can be measured by diffusion tensor imaging (DTI). We obtained DTI whole brain metrics to relate them with allostatic load in subjects of a chilean cohort of cognitive complaint subjects.

Biomarkers.

Background: Dementia impacts the way individuals perceive and describe everyday events. Alzheimer's disease (AD) notably affects processing of entities manifested by nouns, while behavioral variant frontotemporal dementia (bvFTD) often presents a detached, third-person perspective. Yet, the potential of natural language processing tools (NLP) to detect these variations in spontaneous speech remains explored.

Biomarkers.

Background: Detecting Alzheimer's disease (AD) biological hallmarks before clinical symptoms emerge is now possible with available blood-based biomarkers. However, the rate of cognitive decline varies among individuals at risk of AD, and accurate prognostic blood-based biomarkers are lacking. Our goal is to identify plasma proteins predictive of fast cognitive decline in asymptomatic individuals at risk of AD.

Biomarkers.

Background: Chronic exposure to stress, quantified by allostatic load (AL), has been postulated as a cause of structural brain changes in the context of dementia. White matter hyperintensities (WMH), detected in MRI FLAIR, are a common brain abnormality representing small vessel disease or degenerative changes in the brain. Here, we studied differences in tract-specific WMH volume across three risk levels of AL in Chilean subjects with cognitive complaint, to explore links between chronic stress exposure and prodromal steps of dementia.

Biomarkers.

Background: This study examines an exceptional case of CADASIL (Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy), a hereditary cerebrovascular disease caused by a mutation in the notch3 gene. In contrast to typical cases manifesting before the age of 50 with migraines, this report highlights an atypical presentation in a 70-year-old woman with no history of migraines nor cognitive impairment.

Method: The patient, with a history of type 2 diabetes, hypothyroidism, and dyslipidemia, was initially treated for cognitive impairment and behavioral changes under suspicion of autoimmune encephalitis.

Biomarkers.

Background: The exact mechanism underlying amyloid-related imaging abnormalities (ARIA) is unknown. Several factors explain ARIA risk, including the presence of microbleeds, APOE4 carriership, and very low Aβ42 levels. The cerebrospinal fluid (CSF) proteome reflects ongoing mechanisms and, thereby, provides an accessible fluid to refine risk of ARIA development.

Biomarkers.

Background: Alzheimer's disease (AD) blood biomarkers alone can detect amyloid-β (Aβ) pathology in cognitively unimpaired (CU) individuals. We assessed whether combining different plasma biomarkers improves the detection of Aβ-positivity and identifies rapid amyloid deposition in CU individuals.

Method: CU participants from the ALFA+ cohort were included.
