Background: Even patients with normal computed tomography (CT) head imaging may experience persistent symptoms for months to years after mild traumatic brain injury (mTBI). There is currently no good way to predict recovery and triage patients who may benefit from early follow-up and targeted intervention. We aimed to assess if existing prognostic models can be improved by serum biomarkers or diffusion tensor imaging metrics (DTI) from MRI, and if serum biomarkers can identify patients for DTI.

Originating from human psychology, the concepts of "optimism" and "pessimism" were transferred to animal welfare science about 20 years ago to study emotional states in non-human animals. Over time, "optimism" and "pessimism" have developed into valuable welfare indicators, but little focus has been put on the ecological implications of this concept. Here, we aim to bridge this gap and underline the great potential for transferring it to behavioural ecology.

: Aortic pulse wave velocity (aPWV) is a well-established surrogate marker of arterial stiffness. The Antares algorithm offers a method for determining aPWV from oscillometric blood pressure waveforms without requiring additional inputs. This prospective study aimed to evaluate the association and prognostic value of aPWV, determined by Antares, in predicting major adverse cardiovascular events (MACE).

Alberta is home to one of Canada's fastest growing populations of Black people, driven by an influx of African immigrants to major metropolitan areas such as Edmonton and Calgary. As the Black population in Alberta continues to grow, it is crucial to the well-being of these communities that we understand their health service needs. Black women are a vulnerable group within the Black population due to inequities in social determinants of health such as access to healthcare.

Animal research is a matter of intense public debate, with some people supporting and some opposing it. Drawing from examples of behavioural biology, we argue that such an 'all-or-nothing' debate falls short. We highlight the potential of better science communication and tailored ethics assessments to foster a more nuanced view.

Aircraft observations have revealed ubiquitous new particle formation in the tropical upper troposphere over the Amazon and the Atlantic and Pacific oceans. Although the vapours involved remain unknown, recent satellite observations have revealed surprisingly high night-time isoprene mixing ratios of up to 1 part per billion by volume (ppbv) in the tropical upper troposphere. Here, in experiments performed with the CERN CLOUD (Cosmics Leaving Outdoor Droplets) chamber, we report new particle formation initiated by the reaction of hydroxyl radicals with isoprene at upper-tropospheric temperatures of -30 °C and -50 °C.

New particle formation (NPF) in the tropical upper troposphere is a globally important source of atmospheric aerosols. It is known to occur over the Amazon basin, but the nucleation mechanism and chemical precursors have yet to be identified. Here we present comprehensive in situ aircraft measurements showing that extremely low-volatile oxidation products of isoprene, particularly certain organonitrates, drive NPF in the Amazonian upper troposphere.

Article Synopsis
  • Inappropriate therapy (IAT) is a significant issue associated with implantable cardiac defibrillator (ICD) therapy, particularly highlighted in early subcutaneous ICD (S-ICD) studies which showed high rates of inappropriate shocks (IAS).
  • The PRAETORIAN trial, an international study with 849 patients, found no major differences in IAT and IAS rates between S-ICD and transvenous ICD (TV-ICD) groups, as both groups had similar cumulative incidences.
  • Key predictors for IAT varied between the two groups, with TV-ICD patients experiencing IAT mainly from supraventricular tachycardias, while S-ICD patients faced issues from cardiac oversensing

Introduction: Following the formal launch of the AAO-African Chapter in October 2023, there was a renewed interest among African Optometrists to obtain the Fellowship of the American Academy of Optometry (FAAO). This paper investigates the awareness of the FAAO process among African optometrists and their perception of the newly established African Chapter's role in advancing the profession on the continent. The survey addresses a critical gap in understanding and highlights the pivotal role the African Chapter can play in advancing the optometry profession on the continent, contributing valuable insights for shaping strategies to enhance awareness, promote professional development, and foster a sense of belonging among African optometrists within the global optometry community.

Introduction: Despite a high number of long/post-COVID cases and an enormous psychological strain on the part of the patients, no scientific consensus has yet been reached on a clearly defined disease entity. The comprehensive media coverage has made the public more sensitive to this topic, which makes it more difficult to take an objective perspective.

Methods: We report on long/post-COVID symptoms in a hotspot collective of the first SARS-CoV-2 wave of infections in Germany; these infections began in Spring 2020 and therefore preceded the start of an intensive media coverage.

Article Synopsis
  • The S-ICD was created to eliminate lead-related issues found in the TV-ICD, as it is an external device that sits under the skin rather than using leads inside the body.
  • This analysis comes from the PRAETORIAN trial, where patients were randomly assigned to either S-ICD or TV-ICD and assessed for quality of life through various questionnaires at different stages.
  • Results showed no significant differences in physical and mental well-being between the groups, but patients who experienced a shock recently reported lower social functioning and emotional health compared to those who did not.

Background: To what extent and under what conditions electronically captured patient-reported outcomes (ePROs) can be used in routine medical care and contribute to improved patient care is a widely discussed question. In the field of oncology, few studies in Germany have focused this topic that go beyond the scope of time-limited studies.

Method: First, we present the centrally coordinated collection of ePROs in the routine care of a comprehensive cancer center of the German Cancer Aid in its development, and then describe its qualitative dimension.

  • A fungal pathogen affecting low-input apple production has become more widespread in Europe over the past 15 years, yet little is known about its biology and ability to cause disease.
  • This study focused on strain DC1_JKI from Germany, which was sequenced to achieve a comprehensive genome assembly, revealing a mating-type locus identified as MAT1-2.
  • Analysis across European and Asian samples showed that only MAT1-2 was present in European samples, potentially explaining the absence of the sexual reproduction form of the pathogen in European apple orchards.

A search for the exclusive hadronic decays W^{±}→π^{±}γ, W^{±}→K^{±}γ, and W^{±}→ρ^{±}γ is performed using up to 140  fb^{-1} of proton-proton collisions recorded with the ATLAS detector at a center-of-mass energy of sqrt[s]=13  TeV. If observed, these rare processes would provide a unique test bench for the quantum chromodynamics factorization formalism used to calculate cross sections at colliders. Additionally, at future colliders, these decays could offer a new way to measure the W boson mass through fully reconstructed decay products.

Article Synopsis
  • - The ATLAS experiment at the LHC conducted a search for long-lived particles (LLPs) using a large dataset (140 fb^{-1}) from proton-proton collisions at 13 TeV, focusing on LLPs with masses from 5 to 55 GeV that decay within the inner detector.
  • - The study considered scenarios where LLPs are produced from exotic Higgs boson decays and models involving axionlike particles (ALPs).
  • - No significant findings above expected background levels were detected, leading to the establishment of upper limits on various production rates involving the Higgs boson and the top quark related to LLPs and ALPs.

  • The study investigates the associated production of Higgs and W bosons, focusing on how the relative signs of the Higgs couplings to W and Z bosons impact the process.
  • Two specific searches were conducted using large amounts of collision data from the LHC to analyze different coupling scenarios: one for opposite-sign couplings and another for same-sign (standard model-like) couplings.
  • The results significantly exclude the opposite-sign coupling hypothesis and set a strict upper limit on the production rate of this process compared to standard model predictions.

An earlier observational study described selected patients with acute neck pain syndrome, who experienced short bursts of cervical vertigo elicited by rapid head movements. The current study on a larger cohort of 20 patients with chronic or frequently recurring neck pain syndrome and age-matched controls focused on two major questions: (1) Can head movements in subjects with exacerbations of neck pain and restrictions of neck mobility also elicit bursts of vertigo? (2) What is the impact on postural balance measured by analysis of body sway and locomotion? A detailed questionnaire was applied, posture and gait were evaluated by use of instrumented posturography-and gait analysis with and without slow or rapid horizontal head rotations in the yaw plane with and without sight/visual input. All patients reported some or frequent episodes of dizziness in the range of seconds only elicited by rapid, not by slow head movements.

Context: In this study, a small set of 1,3-dipolar cycloaddition reactions that proceed at the same exothermicity is presented. Our main objective was to extend the application of the reaction force constant concept to gain an understanding of the reactivity principles. Inspired by a recent article where we show that the Bell-Evans-Polanyi principle is fulfilled under the condition of an equal degree of (a)synchronicity, here, we demonstrate that the reaction force constant is also a suitable descriptor to quantify the principle of non-perfect synchronization proposed by Bernasconi as a way to understand deviations from the Bell-Evans-Polanyi principle.
