Intraspecific variation of thermal tolerance along elevational gradients: the case of a widespread diving beetle (Coleoptera: Dytiscidae).

Species distributed across wide elevational gradients are likely to experience local thermal adaptation and exhibit high thermal plasticity, as these gradients are characterised by steep environmental changes over short geographic distances (i.e., strong selection differentials).

Genomic, morphological and physiological data support fast ecotypic differentiation and incipient speciation in an alpine diving beetle.

An intricate interplay between evolutionary and demographic processes has frequently resulted in complex patterns of genetic and phenotypic diversity in alpine lineages, posing serious challenges to species delimitation and biodiversity conservation planning. Here we integrate genomic data, geometric morphometric analyses and thermal tolerance experiments to explore the role of Pleistocene climatic changes and adaptation to alpine environments on patterns of genomic and phenotypic variation in diving beetles from the taxonomically complex Agabus bipustulatus species group. Genetic structure and phylogenomic analyses revealed the presence of three geographically cohesive lineages, two representing trans-Palearctic and Iberian populations of the elevation-generalist A.

Parkinson's disease variant detection and disclosure: PD GENEration, a North American study.

Variants in seven genes (LRRK2, GBA1, PRKN, SNCA, PINK1, PARK7 and VPS35) have been formally adjudicated as causal contributors to Parkinson's disease; however, individuals with Parkinson's disease are often unaware of their genetic status since clinical testing is infrequently offered. As a result, genetic information is not incorporated into clinical care, and variant-targeted precision medicine trials struggle to enrol people with Parkinson's disease. Understanding the yield of genetic testing using an established gene panel in a large, geographically diverse North American population would help patients, clinicians, clinical researchers, laboratories and insurers better understand the importance of genetics in approaching Parkinson's disease.

Indeterminate pulmonary nodules and prior malignancy: survival and recurrence after surgery in newly diagnosed stage I non-small cell lung cancer.

Background: Surgical excision biopsy remains the only reliable option in most cases of indeterminate pulmonary nodules, particularly in cancer survivors for whom surgery provides local control of pulmonary metastasis and the best chance of cure for early-stage lung cancer. Nevertheless, unnecessary surgeries remain a concern and the prognosis of newly diagnosed lung cancer might be influenced by the history of previous malignancy. We aimed to analyze the outcomes of resected indeterminate pulmonary nodules in patients with and without previous malignancy, and the impact of prior cancer history on survival and recurrence in stage I non-small cell lung cancer (NSCLC) patients.

Thermal tolerance does not explain the altitudinal segregation of lowland and alpine aquatic insects.

Elevation gradients provide powerful study systems for examining the influence of environmental filters in shaping species assemblages. High-mountain habitats host specific high-elevation assemblages, often comprising specialist species adapted to endure pronounced abiotic stress, while such harsh conditions prevent lowland species from colonizing or establishing. While thermal tolerance may drive the altitudinal segregation of ectotherms, its role in structuring aquatic insect communities remains poorly explored.

Plasticity and associated epigenetic mechanisms play a role in thermal evolution during range expansion.

Due to global change, many species are shifting their distribution and are thereby confronted with novel thermal conditions at the moving range edges. Especially during the initial phases of exposure to a new environment, it has been hypothesized that plasticity and associated epigenetic mechanisms enable species to cope with environmental change. We tested this idea by capitalizing on the well-documented southward range expansion of the damselfly from France into Spain where the species invaded warmer regions in the 1950s in eastern Spain (old edge region) and in the 2010s in central Spain (new edge region).

Epileptiform electroencephalogram discharges increase seizure recurrence risk in patients with acute symptomatic seizure due to a structural brain lesion.

Objective: The risk factors for seizure recurrence after acute symptomatic seizure due to a structural brain lesion are not well established. The aim of this study was to analyze possible associations between demographic, clinical, and electroencephalographic variables and epilepsy development in patients with acute symptomatic seizure due to an acute structural brain lesion.

Methods: We designed an observational prospective study of patients with acute symptomatic seizure due to an acute structural brain lesion (hemorrhagic stroke, ischemic stroke, traumatic brain injury, or meningoencephalitis) who underwent EEG during their initial admission between January 2015 and January 2020.

Readiness for Parkinson's disease genetic testing and counseling in patients and their relatives in urban settings in the Dominican Republic.

Genetic testing for Parkinson's disease (PD) is increasing globally, and genetic counseling is an important service that provides information and promotes understanding about PD genetics and genetic testing. PD research studies have initiated outreach to underrepresented regions in North America, including regions in Latin America, such as the Dominican Republic (DR); some studies may include return of genetic test results. Thus, understanding what individuals know about PD, genetic testing for PD, and their interest in speaking with a genetic counselor, is crucial when assessing readiness.

AraC interacts with p75 transmembrane domain to induce cell death of mature neurons.

Cytosine arabinoside (AraC) is one of the main therapeutic treatments for several types of cancer, including acute myeloid leukaemia. However, after a high-dose AraC chemotherapy regime, patients develop severe neurotoxicity and cell death in the central nervous system leading to cerebellar ataxia, dysarthria, nystagmus, somnolence and drowsiness. AraC induces apoptosis in dividing cells.

Clinical Profile and Determinants of Mortality in Patients with Interstitial Lung Disease Admitted for COVID-19.

Background: Concern has risen about the effects of COVID-19 in interstitial lung disease (ILD) patients. The aim of our study was to determine clinical characteristics and prognostic factors of ILD patients admitted for COVID-19.

Evaluation of functional warm ischemia time during controlled donation after circulatory determination of death using normothermic regional perfusion (ECMO-TT): A prospective multicenter cohort study.

Background: Controlled donation after circulatory determination of death (cDCD) seems an effective way to mitigate the critical shortage of available organs for transplant worldwide. As a recently developed procedure for organ retrieval, some questions remain unsolved such as the uncertainty regarding the effect of functional warm ischemia time (FWIT) on organs´ viability.

Methods: We developed a multicenter prospective cohort study collecting all data from evaluated organs during cDCD from 2017 to 2020.

Low Energy Structures in Nuclear Reactions with 4n in the Final State.

We investigate a reaction model that describes a fast removal of the α particle from the ^{8}He nucleus with eventual emission of four neutrons. The obtained four neutron energy distribution allows one to explain the sharp low energy peak observed by studying the missing mass spectra of four neutrons in Duer et al. [Nature (London) 606, 678 (2022)NATUAS0028-083610.

Inhaled Sedation in Patients with COVID-19-Related Acute Respiratory Distress Syndrome: An International Retrospective Study.

Background And Objectives: The coronavirus disease 2019 (COVID-19) pandemic and the shortage of intravenous sedatives has led to renewed interest in inhaled sedation for patients with acute respiratory distress syndrome (ARDS). We hypothesized that inhaled sedation would be associated with improved clinical outcomes in COVID-19 ARDS patients.

Methods: Retrospective international study including mechanically ventilated patients with COVID-19 ARDS who required sedation and were admitted to 10 European and US intensive care units.

The covid-19 pandemic and the usability of telehealth in a midlife women's health integrated care program.

Aim: To investigate the usability of telephone-based telehealth in a women's health outpatient clinic and whether this may be affected by the severity of the COVID pandemic.

Early and Delayed Infarct Growth in Patients Undergoing Mechanical Thrombectomy: A Prospective, Serial MRI Study.

Background: We studied the evolution over time of diffusion weighted imaging (DWI) lesion volume and the factors involved on early and late infarct growth (EIG and LIG) in stroke patients undergoing endovascular treatment (EVT) according to the final revascularization grade.

Methods: This is a prospective cohort of patients with anterior large artery occlusion undergoing EVT arriving at 1 comprehensive stroke center. Magnetic resonance imaging was performed on arrival (pre-EVT), <2 hours after EVT (post-EVT), and on day 5.

Sources of excess steroid prescriptions and clinical adverse outcomes associated with steroid excess in patients with inflammatory bowel disease: The Leeds IBD Steroids study.

Background: Corticosteroids remain important for managing inflammatory bowel disease (IBD) flares. Steroid excess, however, may be a marker of poor care. Patients access steroid prescriptions from primary (General Practitioners [GP]) or secondary care (hospital-based).

A set of accessible enhancers enables the initial response of breast cancer cells to physiological progestin concentrations.

Here, we report that in T47D breast cancer cells 50 pM progestin is sufficient to activate cell cycle entry and the progesterone gene expression program. At this concentration, equivalent to the progesterone blood levels found around the menopause, progesterone receptor (PR) binds only to 2800 genomic sites, which are accessible to ATAC cleavage prior to hormone exposure. These highly accessible sites (HAs) are surrounded by well-organized nucleosomes and exhibit breast enhancer features, including estrogen receptor alpha (ERα), higher FOXA1 and BRD4 (bromodomain containing 4) occupancy.

Convergence of life history and physiology during range expansion toward the phenotype of the native sister species.

In our globally changing planet many species show range expansions whereby they encounter new thermal regimes that deviate from those of their source region. Pressing questions are to what extent and through which mechanisms, plasticity and/or evolution, species respond to the new thermal regimes and whether these trait changes are adaptive. Using a common-garden experiment, we tested for plastic and evolutionary trait changes in life history and a set of understudied biochemical/physiological traits during the range expansion of the damselfly Ischnura elegans from France into a warmer region in Spain.

Endovascular and medical therapy of May-Thurner syndrome: Case series and scoping literature review.

Introduction: May-Thurner syndrome has been recognized as a cause of chronic venous insufficiency and a trigger for venous thromboembolism. There is no consensus about the definition, diagnosis, and therapeutic approach. We are aiming to describe its characteristics and a scoping literature review.

Evolution of cold tolerance and thermal plasticity in life history, behaviour and physiology during a poleward range expansion.

Many species that are moving polewards encounter novel thermal regimes to which they have to adapt. Therefore, rapid evolution of thermal tolerance and of thermal plasticity in fitness-related traits in edge populations can be crucial for the success and speed of range expansions. We tested for adaptation in cold tolerance and in life history, behavioural and physiological traits and their thermal plasticity during a poleward range expansion.

Patients with inflammatory bowel disease (IBD) prefer oral tablets over other modes of medicine administration.

: With increasing treatment choices for inflammatory bowel disease (IBD), patients' preferences should be considered to limit non-adherence. We explored patients' preferences for route, form and frequency of medication administration, and factors influencing these choices.: Patients rated acceptability of different forms of medication on 10-point Likert scales and preferences for highest acceptable frequency.

A multidisciplinary approach and implementation of a specialized hemorrhage control team improves outcomes for placenta accreta spectrum.

Introduction: The main complication of placenta accreta spectrum (PAS) is massive bleeding. Endoarterial occlusion techniques have been incorporated into the management of this pathology. Our aim was to examine the endovascular practice patterns among PAS patients treated during a 9-year period in a low-middle income country in which an interdisciplinary group's technical skills were improved with the creation of a PAS team.
