Natural-Looking Ears after Otoplasty with a Modified Anterior Scoring Technique.

The correction of prominent ears is a rewarding operation. When choosing a surgical technique, we prefer a cartilage-sparing technique to a cartilage-splitting technique to achieve natural-looking long-term results. In this article, we present our preferred technique of an anterior scoring technique combined with concha-mastoid sutures step by step.

Decipher 'Em All: A Profiling Study on the Effects of Acyl Groups in -Acyl-ω-hydroxy Fatty Acids.

The -acyl-ω-hydroxy fatty acids (OAHFAs) are an intriguing class of surface-active lipids which can be found in the human tear film lipid layer (TFLL). Recent studies have suggested that OAHFAs exist in the polar lipid layer and play a central role in TFLL function. Surprisingly, biophysical profiling studies have only shed light on the properties of OAHFAs bearing an oleate acyl group and insights on species with other acyl groups are scarce.

[Current diagnostics and therapy in chronic rhinosinusitis].

Chronic rhinosinusitis is a prevalent condition with significant implications for both patients and society at large. The diagnostic and treatment approaches are primarily guided by the EPOS2020 guidelines in Europe, which increasingly delve into the molecular -mechanism of the disease and its resulting phenotypes. In recent years, biologics have emerged as a promising option, in particular for cases that are refractory to conventional therapies.

Despite Recovery from Necrotizing Enterocolitis Infants Retain a Hyperinflammatory Response to Injury.

Background: Necrotizing enterocolitis (NEC) is the leading gastrointestinal cause of death of premature neonates. NEC is associated with prematurity, a hyperinflammatory response, and dysregulation of intestinal barrier function. We hypothesize that patients with NEC will have, and continue to have after recovery, an increased hyperinflammatory intestinal response compared to those patients without NEC.

Caveolin-1: A Review of Intracellular Functions, Tissue-Specific Roles, and Epithelial Tight Junction Regulation.

Caveolin-1 (Cav1) is a vital protein for many cellular processes and is involved in both the positive and negative regulation of these processes. Cav1 exists in multiple cellular compartments depending on its role. Of particular interest is its contribution to the formation of plasma membrane invaginations called caveolae and its involvement in cytoskeletal interactions, endocytosis, and cholesterol trafficking.

Early-Stage Development of an Anti-Evaporative Liposomal Formulation for the Potential Treatment of Dry Eyes.

Dry eye disease (DED), the most common ocular disorder, reduces the quality of life for hundreds of millions of people annually. In healthy eyes, the tear film lipid layer (TFLL) stabilizes the tear film and moderates the evaporation rate of tear fluid. In >80% of DED cases, these central features are compromised leading to tear film instability and excessive evaporation of tear fluid.

Accuracy and Reliability of Chatbot Responses to Physician Questions.

Importance: Natural language processing tools, such as ChatGPT (generative pretrained transformer, hereafter referred to as chatbot), have the potential to radically enhance the accessibility of medical information for health professionals and patients. Assessing the safety and efficacy of these tools in answering physician-generated questions is critical to determining their suitability in clinical settings, facilitating complex decision-making, and optimizing health care efficiency.

Objective: To assess the accuracy and comprehensiveness of chatbot-generated responses to physician-developed medical queries, highlighting the reliability and limitations of artificial intelligence-generated medical information.

Reconstructive ossiculoplasty options in primary cholesteatoma surgeries with an intact stapes.

Purpose: In primary cholesteatoma patients, incus destruction with an intact and mobile stapes is a frequent finding. Different techniques have been described to restore the ossicular chain, including incus interposition, stapes augmentation and type III tympanoplasty. Controversy about postoperative hearing results in open versus closed surgical techniques exist.

Response of the Glutathione (GSH) Antioxidant Defense System to Oxidative Injury in Necrotizing Enterocolitis.

Necrotizing enterocolitis (NEC) is a neonatal intestinal disease associated with oxidative stress. The targets of peroxidation and the role of the innate intestinal epithelial antioxidant defense system are ill-defined. We hypothesized that oxidative stress in NEC correlates with oxidized GSH redox potentials, lipid peroxidation, and a dysfunctional antioxidant system.

Persistent Proclivity to a Proinflammatory State in a Human Enteroid Model of Necrotizing Enterocolitis.

Necrotizing enterocolitis (NEC) is a devastating disease of premature neonates with substantial morbidity and mortality. Necrotizing enterocolitis is associated with prematurity, a hyperinflammatory response, and dysregulation of intestinal barrier function. We hypothesize that patients with NEC will have an increased hyperinflammatory intestinal response compared with those without NEC.

Clinical reasoning: What do nurses, physicians, and students reason about.

Clinical reasoning is a core ability in the health professions, but the term is conceptualised in multiple ways within and across professions. For interprofessional teamwork it is indispensable to recognise the differences in understanding between professions. Therefore, our aim was to investigate how nurses, physicians, and medical and nursing students define clinical reasoning.

Apical-Out Enteroids as an Innovative Model for Necrotizing Enterocolitis.

Introduction: Necrotizing enterocolitis (NEC) is a gastrointestinal disease of premature neonates. We previously validated a NEC enteroid model derived from human infant intestinal tissue. Typical enteroid configuration is basolateral-out (BO) without direct access to the luminal (apical) surface.

Assessing the Accuracy and Reliability of AI-Generated Medical Responses: An Evaluation of the Chat-GPT Model.

Background: Natural language processing models such as ChatGPT can generate text-based content and are poised to become a major information source in medicine and beyond. The accuracy and completeness of ChatGPT for medical queries is not known.

Methods: Thirty-three physicians across 17 specialties generated 284 medical questions that they subjectively classified as easy, medium, or hard with either binary (yes/no) or descriptive answers.

Interpreting the risk analysis index of frailty in the context of surgical oncology.

Background And Objectives: The Risk Analysis Index (RAI) accurately predicts adverse postoperative outcomes but the inclusion of cancer status in the RAI has raised two key concerns about its suitability for use in surgical oncology: (1) the potential over classification of cancer patients as frail, and (2) the potential overestimation of postoperative mortality for patients with surgically curable cancers.

Methods: We performed a retrospective cohort analysis to assess the RAI's power to appropriately identify frailty and predict postoperative mortality in cancer patients. We assessed discrimination for mortality and calibration across five RAI models-the complete RAI and four variants that removed different cancer-related variables.

[Bavarian online database for corona screening tests-development and use of a digital solution in the pandemic].

During the SARS-CoV‑2 pandemic, various data had to be collected to support political decisions for pandemic preparedness and response. Nevertheless, using analogue tools like paper and pencil as well as sending files with media discontinuity that have to be merged later are not useful and can hardly provide usable data in real time. With the selected system architecture, the Bavarian Online Database for Corona Screening Tests (BayCoRei) is a central, Bavaria-wide, consistent digital solution that is agile and easy to use.

Sphingolipid subtypes differentially control proinsulin processing and systemic glucose homeostasis.

Impaired proinsulin-to-insulin processing in pancreatic β-cells is a key defective step in both type 1 diabetes and type 2 diabetes (T2D) (refs. ), but the mechanisms involved remain to be defined. Altered metabolism of sphingolipids (SLs) has been linked to development of obesity, type 1 diabetes and T2D (refs.

Selective ablation of P53 in pancreatic beta cells fails to ameliorate glucose metabolism in genetic, dietary and pharmacological models of diabetes mellitus.

Objective: Beta cell dysfunction and death are critical steps in the development of both type 1 and type 2 diabetes (T1D and T2D), but the underlying mechanisms are incompletely understood. Activation of the essential tumor suppressor and transcription factor P53 (also known as TP53 and Trp53 in mice) was linked to beta cell death in vitro and has been reported in several diabetes mouse models and beta cells of humans with T2D. In this article, we set out to determine the beta cell specific role of P53 in beta cell dysfunction, cell death and development of diabetes in vivo.

Determining Intestinal Permeability using Lucifer Yellow in an Apical-Out Enteroid Model.

Enteroids are an emerging research tool in the study of inflammatory bowel diseases such as necrotizing enterocolitis (NEC). They are traditionally grown in the basolateral-out (BO) conformation, where the apical surface of the epithelial cell faces the inner lumen. In this model, access to the luminal surface of enteroids for treatment and experimentation is challenging, which limits the ability to study host-pathogen interactions.

[Interprofessional Training for Discharge Planning: Effects of Self-Efficacy in Nursing and Medical Students].

Interprofessional Training for Discharge Planning: Effects of Self-Efficacy in Nursing and Medical Students Concordant and methodical briefing about a patient's disposition for discharge from hospital within the interprofessional ward round can facilitate a timely discharge. However, interprofessional ward rounds require not only professional skills but also knowledge of interprofessional cooperation between all the occupational groups involved. The question arose whether students of the various professions could learn the necessary competencies during their studies.

Decreased expression of hypoxia-inducible factor 1α (HIF-1α) in cord blood monocytes under anoxia.

Background: Infections are a major cause for morbidity and mortality in neonates; however, the underling mechanisms for increased infection susceptibility are incompletely understood. Hypoxia, which is present in inflamed tissues, has been identified as an important activation signal for innate immune cells in adults and is mainly mediated by hypoxia-inducible factor 1α (HIF-1α). Fetal tissue pO physiologically is low but rises immediately after birth.

COVID-19 case findings and contact tracing in South German nursing homes.

Background: The air borne SARS-CoV-2 poses a high threat to the elderly and people with underlying diseases. COVID-19 spread quickly in South German nursing homes and for this reason called for preventive measures by the German government. The aim of this paper is to showcase the testing strategies implemented by the Public Health Department Reutlingen to control the spread of COVID-19 in local nursing homes and to report the results thereof.

Stapled Full-Thickness Diaphragm Resection: A Novel Approach to Diaphragmatic Resection in Cytoreductive Surgery with Hyperthermic Intraperitoneal Chemotherapy.

Full-thickness diaphragm resection (FT-DR) during cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) is sometimes required to achieve a complete cytoreduction. It is conventionally performed with electrocautery with primary repair or mesh repair. FT-DR using a linear cutting stapler is a novel technique that avoids entry to the chest cavity and minimizes the use of electrocautery on the diaphragm.

[Teaching Interprofessional Patient Pathways in Medical Education in Switzerland - A Collaboration of Multiple Players].

Teaching Interprofessional Patient Pathways in Medical Education in Switzerland - A Collaboration of Multiple Players The increase of chronic and complex medical disorders challenges actors in the health care system and affects the entire health care system in Switzerland. Through an interprofessional exchange between medical and health care professionals, the individual needs of patients can be better addressed, which has a positive impact on patients' treatments. To prepare students of the Bachelor of Medicine at ETH Zurich for these challenges, the ETH has designed a specific course together with four educational institutions, which is oriented towards the interprofessional, patient-centred supply chain.
