Aim: The aim of this study was to investigate patient-reported outcomes (PROs) following lumbar discectomy on patients with lateral lumbar disc herniation (LDH) compared to patients with paramedian LDH.

Background: Surgery for disc herniation is one of the most common procedures of the lumbar spine. LDHs can be divided into median, paramedian, foraminal and extraforaminal types based on the anatomical site of the lesion.

Introduction: While diagnosis rates of autism spectrum disorders (ASD) and attention deficit hyperactivity disorder (ADHD) vary within countries at a large-scale municipal level, small neighbourhood geographic variation remains understudied. In this nationwide study, we describe the rates of ASD and ADHD diagnoses in children and adults by geographical data zones of approximately 2,500 residents across Denmark.

Methods: We included a population of children born from 1993 through 2020 and an adult population born from 1977 through 2003.

Meningiomas are the most common primary central nervous system tumor. Clinical trials have failed to support effective medical treatments, despite initially promising animal studies. A key issue could be that available experimental models fail to mimic the clinical situation.

Introduction: Parkinson's disease (PD) is a progressive neurodegenerative disease, and biomarkers are needed to enhance earlier detection and monitoring. Alpha-synuclein, phosphorylated at serine 129 (pS129-α-syn), is the predominant form of α-syn found in Lewy bodies implicating an involvement in disease pathology. This review aims to systematically evaluate the evidence for pS129-α-syn detection in human biofluid samples of PD utilizing ELISA-based protein detection methods.

Background: Systematic reviews within the field of animal research are becoming more common. However, in animal translational research, issues related to methodological quality and quality of reporting continue to arise, potentially leading to underestimation or overestimation of the effects of interventions or prevent studies from being replicated. The various tools and checklists available to ensure good-quality studies and proper reporting include both unique and/or overlapping items and/or simply lack necessary elements or are too situational to certain conditions or diseases.

Objective: To investigate whether hearing-aid fitting based on user-operated audiometry is non-inferior to hearing-aid fitting based on traditional audiometry.

Design: This non-inferiority randomised clinical trial, took place at Odense University Hospital, Odense, Denmark. In a first visit, participants were tested with traditional audiometry as well as user-operated audiometry and filled in the Speech, Spatial and Qualities of Hearing Scale (SSQ12) at baseline.

Article Synopsis
  • This paper explores silver gallium selenide (AGSe) as a better option than silver gallium sulfide (AGS) for detecting infrared signals beyond 10 µm, particularly in the 10 to 20 µm range.
  • AGSe has a wider transparency range up to approximately 20 µm, while AGS has limitations due to high absorption beyond 12 µm.
  • Experimental comparisons show that AGSe achieves higher upconversion efficiency and better phase matching, making it a strong candidate for long-wavelength infrared detection applications.

Importance: Research suggests an increase in mental disorder incidence in recent years, but this trend remains unexplained, and there is a lack of large studies based on a representative sample that investigate mental disorders over the full spectrum.

Objective: To explore sex- and age-specific incidence of any mental disorder and 19 specific disorders according to birth cohort and calendar period.

Design, Setting, And Participants: This was a population-based cohort study among 5 936 202 individuals aged 1 to 80 years living in Denmark at some point between January 1, 2004, and December 31, 2021.

Article Synopsis
  • The study investigates how self-promoted N-glycosylations work through experiments that test reaction rates, computer simulations, and competing reactions with different nucleophiles.
  • It proposes that the reaction starts with a proton transfer from a sulfonyl carbamate to a trichloroacetimidate, forming an ion pair that leads to a specific intermediate structure.
  • The findings suggest that the reaction produces specific stereoisomers because of the nature of the intermediates, and the sulfonyl carbamates can act as catalysts when competing nucleophiles are present.

Purpose: Intracranial pressure (ICP) control is important to avoid secondary brain injury in patients with intracranial pathologies. Current methods for measuring ICP are invasive and carry risks of infection and hemorrhage. Previously we found correlation between ICP and the arteriole-venous ratio (A/V ratio) of retinal vessels in an outpatient setting.

Prostate tumor heterogeneity is a major obstacle when studying the biological mechanisms of molecular markers. Increased gene expression levels of secreted frizzled-related protein 4 (SFRP4) is a biomarker in aggressive prostate cancer. To understand how SFRP4 relates to prostate cancer we performed comprehensive spatial and multiomics analysis of the same prostate cancer tissue samples.

Gluconolactone serves as a readily available and inexpensive starting material for synthesizing the potential platform chemical (Z)-3-deoxy-1,2 : 5,6-di-O-isopropylidene-D-erythro-hex-3-enolactone in two steps. In this work, the selective elimination of triacetone gluconolactone was optimized. The resulting product is a versatile molecule, capable of being transformed into various compound classes in one or a few steps, i.

Extracellular vesicles, including exosomes, are small extracellular vesicles that range in size from 30 nm to 10 μm in diameter and have specific membrane markers. They are naturally secreted and are present in various bodily fluids, including blood, urine, and saliva, and through the variety of their internal cargo, they contribute to both normal physiological and pathological processes. These processes include immune modulation, neuronal synapse formation, cell differentiation, cancer metastasis, angiogenesis, lymphangiogenesis, progression of infectious disease, and neurodegenerative disorders like Alzheimer's and Parkinson's disease.

Background: The aim of this study was to investigate the perioperative outcomes of robotic liver surgery (RLS) and Open liver surgery (OLS) in a centre with a high number of operations.

Methods: A 1:1 propensity score matched (PSM) analysis of a retrospective database of RLS and OLS was performed. Cumulative sum (CUSUM) analysis was performed to identify learning curves.

  • Black communities in Canada are significantly affected by HIV, with low uptake of PrEP, a key prevention method, among eligible individuals.
  • A study in Toronto revealed that many Black clients experience decisional conflict and unmet needs when making choices about starting and adhering to PrEP.
  • To address this, researchers developed a decision support tool (DST) using a structured 7-step process, involving various stakeholders, to enhance decision-making about PrEP among Black clients, focusing on its acceptability and usability.

Article Synopsis
  • Researchers studied how surviving childhood leukemia (ALL) might affect mental health as kids grow up.
  • They looked at almost 2,000 survivors and compared them to their siblings and other kids to see who had more psychiatric problems by age 30.
  • They found that survivors had a slightly higher chance of mental health issues, especially those who had serious treatments, but overall, the risks were similar to their siblings and friends.

Proton exchange membrane water electrolysis (PEMWE) is a promising technology to produce hydrogen directly from renewable electricity sources due to its high power density and potential for dynamic operation. Widespread application of PEMWE is, however, currently limited due to high cost and low efficiency, for which high loading of expensive iridium catalyst and high OER overpotential, respectively, are important reasons. In this study, we synthesize highly dispersed IrRu nanoparticles (NPs) supported on antimony-doped tin oxide (ATO) to maximize catalyst utilization.

Background: Viral infection is a common trigger of severe respiratory illnesses in early life and a risk factor for later asthma development. The mechanism leading to asthma could involve an aberrant airway immune response to viral infections, but this has rarely been studied in a human setting.

Objectives: To investigate in situ virus-specific differences in upper airway immune mediator levels during viral episodes of respiratory illnesses and the association with later asthma.
