Selective arm-usage of pre-miR-1307 dysregulates angiogenesis and affects breast cancer aggressiveness.

Background: Breast cancer is the leading cause of cancer-related mortality in women. Deregulation of miRNAs is frequently observed in breast cancer and affects tumor biology. A pre-miRNA, such as pre-miR-1307, gives rise to several mature miRNA molecules with distinct functions.

Effects of genetic ablation and pharmacological inhibition of HuR on gene expression, iron metabolism, and hormone levels.

Background: HuR/ELAV1, a ubiquitous RNA-binding protein, belongs to the RNA-binding protein family and is crucial for stabilizing and regulating the translation of various mRNA targets, influencing gene expression. Elevated HuR levels are associated with multiple disorders, including cancer and neurodegenerative diseases. Despite the identification of small molecule inhibitors targeting HuR, their detailed characterization remains limited.

Satisfied with the worst health outcomes or unsatisfied with the best: explaining the divergence between good patient-reported outcomes and low satisfaction and vice versa among knee arthroplasty patients - a retrospective cohort study.

Objectives: Total knee arthroplasty (TKA) is an effective treatment for patients with end-stage knee osteoarthritis but some patients exhibit a discrepancy between patient-reported outcomes (PROs) and patient satisfaction (PS). This study aims to identify predictors for patients reporting unfavorable PROs but high PS and vice versa.

Materials And Methods: This retrospective cohort study categorized patients from nine German hospitals into four groups based on (i) whether they achieved a minimal clinically important difference (MCID) in knee functionality, measured with a joint-specific PRO from admission to 12-month post-surgery; and (ii) whether they were satisfied at 12 months post-surgery.

Fast vocal-motor tracking of escaping prey in echolocating bats.

Background: Echolocating bats face an intense arms race with insect prey that can detect bat calls and initiate evasive maneuvers. Their high closing speeds and short biosonar ranges leave bats with only a few 100 ms between detection and capture, suggesting a reactive sensory-motor operation that might preclude tracking of escaping prey. Here we test this hypothesis using greater mouse-eared bats (Myotis myotis) as a model species.

An interactive course program on nutrition for medical students: interdisciplinary development and mixed-methods evaluation.

Nutrition plays a crucial role in human and planetary health, as prevailing nutritional patterns significantly contribute to the global non-communicable disease pandemic. Moreover, the global food system is inextricably linked to planetary health deterioration. The relevance of nutrition for individual and planetary health is insufficiently addressed in German medical schools.

Minimally invasive management of hidradenitis suppurativa using a 1470 nm diode laser: a step-by-step description of our technique.

Background: The management of hidradenitis suppurativa (HS) requires a multidisciplinary approach to ensure sustainable treatment results, especially in the advanced stages. Traditionally, deroofing and wide excision represented commonly employed surgical techniques. Due to the recurrent nature of HS, tissue preservation should be a relevant aspect of surgical management.

Lifestyle scores and their potential to estimate the risk of multiple non-communicable disease-related endpoints: a systematic review.

Background: Lifestyle scores have emerged as a practical tool to assess the risk of major non-communicable diseases (NCDs). However, most of them are primarily developed for single NCDs. Given the common risk factors for some of the major NCDs, we conducted a systematic review to evaluate the potential of existing lifestyle scores in predicting the risk of multiple NCD-related endpoints.

Ramadan during pregnancy and the role of dietary intake for neonatal health in Kaduna, Northwestern Nigeria: a cross-sectional study.

Background: Ramadan during pregnancy is associated with adverse offspring health outcomes. Recent evidence from Europe indicates that maternal diet during non-fasting hours might alleviate these effects. This study describes fasting, diet, and sleep habits among pregnant Muslims in Kaduna, Nigeria, and assesses impacts on neonatal health in this setting.

Prolonged pain-to-balloon time still impairs midterm left ventricular function following STEMI.

Background: ST-elevation myocardial infarction (STEMI) demands near-time reperfusion to reduce the risk of long-term heart failure. This study evaluates the proportion of impaired left ventricular ejection fraction (LVEF) following STEMI in the context of current healthcare settings at a tertiary care center equipped with the most advanced and up-to-date standards of care.

Methods: Patients experiencing STEMI as their first manifestation of coronary artery disease were analyzed, as these individuals had no prior experience with heart-related chest pain.

Psychosocial working conditions and violence prevention climate in German emergency departments - a cross-sectional study.

Background: Emergency departments (EDs) are high pressure work environments with several psychosocial job demands, e.g., violence, and job resources, e.

DenseSeg: joint learning for semantic segmentation and landmark detection using dense image-to-shape representation.

Purpose: Semantic segmentation and landmark detection are fundamental tasks of medical image processing, facilitating further analysis of anatomical objects. Although deep learning-based pixel-wise classification has set a new-state-of-the-art for segmentation, it falls short in landmark detection, a strength of shape-based approaches.

Methods: In this work, we propose a dense image-to-shape representation that enables the joint learning of landmarks and semantic segmentation by employing a fully convolutional architecture.

Reducing cheap talk? How monetary incentives affect the accuracy of metamemory judgments.

The accuracy of metacognitive judgments is rarely incentivized in experiments; hence, it depends on the participants' willingness to invest cognitive resources and respond truthfully. According to arguments promoted in economic research that performance cannot reach its full potential without proper motivation, metacognitive abilities might therefore have been underestimated. In two experiments (N = 128 and N = 129), we explored the impact of incentives on the accuracy of judgments of learning (JOLs), memory performance, and cue use in free recall of word lists.

Co-culture of Helicobacter pylori with oral microorganisms in human saliva.

Objective: Helicobacter pylori is known for colonizing the gastric mucosa and instigating severe upper gastrointestinal diseases such as gastritis, gastroduodenal ulcers, and gastric cancer. To date, there is no data available on the oral cavity as transmission site, whether H. pylori can survive in the oral cavity or in human saliva.

Stromal PDGFR-beta expression is a prognostic factor in high-grade serous ovarian cancer patients but is it also predictive for response to antiangiogenic treatment?

Objective: In advanced ovarian cancer, the majority of patients receive anti-angiogenic treatment with bevacizumab. However, its use is often associated with severe side effects, and not all patients benefit from the therapy. Currently, there are no reliable biomarkers to predict response to treatment.

CT angiography of acute aortic syndrome in patients with chronic kidney disease.

The term acute aortic syndrome (AAS) refers to a range of different entities, including dissection, intramural haematoma and penetrating atherosclerotic ulcer. Patients with chronic renal disease and particularly those with dominant polycystic kidney disease are susceptible to this pathology, given the underlying renal arteriopathy and hypertension. Imaging plays a crucial role in diagnosing, grading and guiding management of these patients, with computed tomography angiography (CTA) being on the frontline.

Drug interactions in a sample of inpatients diagnosed with cannabis use disorder.

The majority of patients with cannabis use disorder (CUD) regularly take medication. Cannabinoids influence metabolism of some commonly prescribed drugs. However, little is known about the characteristics and frequency of potential cannabis-drug (CDIs) and drug-drug interactions (DDIs) in patients with CUD.

Probing the properties of PTEN specific botulinum toxin type E mutants.

Botulinum neurotoxins (BoNT) are established biopharmaceuticals for neuromuscular and secretory conditions based on their ability to block neurotransmitter release from neurons by proteolyzing specific soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) proteins. Recently, a mutant catalytic domain of serotype E (LC/E) exhibiting 16 mutations was reported to cleave the phosphatase and tensin homolog (PTEN). This molecule represents an attractive new target in neurons as several reports support PTEN knockdown as a strategy to stimulate axonal regeneration after injury.

Prognostic and clinical heterogeneity of PD1 and PD-L1- immunohistochemical scores in endometrial cancers.

Introduction: PD1/PD-L1 inhibition (ICi) has recently become a new standard of care for patients with advanced MMR-deficient (MMRd) endometrial cancers. Nevertheless, response to immunotherapy is more complex than the presence of a single biomarker and therefore it remains challenging to predict patients response to ICi beyond MMRd tumors. Elevated PD-L1 expression (CPS ≥ 1) is often used as a prognostic marker as well as a predictive biomarker of response to ICi in different tumor types.

A living library concept to capture the dynamics and reactivity of mixed-metal clusters for catalysis.

The exploration of ligated metal clusters' chemical space is challenging, partly owing to an insufficiently targeted access to reactive clusters. Now, dynamic mixtures of clusters, defined as living libraries, are obtained through organometallic precursor chemistry. The libraries are populated with interrelated clusters, including transient and highly reactive ones, as well as more accessible but less reactive species.

Associations of inferior frontal sulcal hyperintensities on brain MRI with cerebral small vessel disease, cognitive function, and depression symptoms.

Inferior frontal sulcal hyperintensities (IFSH) observed on fluid-attenuated inversion recovery (FLAIR) MRI have been proposed as indicators of elevated cerebrospinal fluid waste accumulation in cerebral small vessel disease (CSVD). However, to validate IFSH as a reliable imaging biomarker, further replication studies are required. The objective of this study was to investigate associations between IFSH and CSVD, and their potential repercussions, i.

Long-term effects of SARS-CoV-2 infection and vaccination in a population-based pediatric cohort.

During the omicron wave of the COVID-19 pandemic and with SARS-CoV-2 vaccines becoming available, seroprevalence rates rose in children and adolescents. This study investigated the impact of both SARS-CoV-2 infections and vaccinations on the incidence of acute and prolonged symptoms in real-world conditions during the transition from the pandemic to the endemic phase. Participants from a pediatric population based seroprevalence study (CorKID study) were followed up at least two and for almost four years by survey of health status features and symptoms suggestive of post-COVID syndrome (PCS).
