Referral, monitoring, and factors associated with non-referral of chronic kidney disease in Germany: a nationwide, retrospective cohort study.

Background: Chronic kidney disease (CKD) is one of the most significant drivers of the global burden of disease and an increasing public health issue. Adequate monitoring and referral of high-risk patients to nephrologists are associated with improved management of CKD. We aimed to assess nephrology referral rates, monitoring of kidney function, and factors associated with failure to refer in Germany.

Wetting behavior in the inertial phase of droplet impacts onto sub-millimeter microstructured surfaces.

Hypothesis: The shape of the wetted region after a droplet impact can vary significantly even in the early phase of the process. How much of the early spreading process occurs within the structures versus above the structures, flow regimes and local wetting at groove intersections can have effects on the sizes and shapes of the final wetted regions. Experiments and simulations: We experimentally study droplet impacts onto cubic pillars with , and side length, height and separation.

'Incense is the one that keeps the air fresh': indoor air quality perceptions and attitudes towards health risk.

Background: Air pollution is of significant environmental and public health concern globally. While much research has historically focused on outdoor air pollution, indoor air pollution has been relatively under-explored despite its strong connection with health outcomes, particularly respiratory health. Studies on air pollution exposure mitigation consistently reveal a significant knowledge gap between the understanding of air pollution as a health risk among lay individuals and expert scientists.

Concurrent optogenetic motor mapping of multiple limbs in awake mice reveals cortical organization of coordinated movements.

Background: Motor mapping allows for determining the macroscopic organization of motor circuits and corresponding motor movement representations on the cortex. Techniques such as intracortical microstimulation (ICMS) are robust, but can be time consuming and invasive, making them non-ideal for cortex-wide mapping or longitudinal studies. In contrast, optogenetic motor mapping offers a rapid and minimally invasive technique, enabling mapping with high spatiotemporal resolution.

Determinants of Prognosis in Head and Neck Cutaneous Squamous Cell Carcinoma With Nodal Metastases.

Importance: The eighth edition tumor, node, metastasis (TNM) staging for head and neck cutaneous squamous cell carcinoma (HNcSCC) is a poor predictor of survival in patients with lymph node metastases, possibly due to the inclusion of extranodal extension (ENE).

Objective: To identify the key determinants of prognosis in patients with nodal metastatic HNcSCC and analyze the association of ENE with TNM stage and investigate for prognostic heterogeneity in ENE-positive disease.

Design, Setting, And Participants: This retrospective, multicenter cohort study was conducted at 4 Australian tertiary referral centers using prospectively collected data in patients treated between 1980 and 2017 with a median (IQR) follow-up of 3.

Dogs distinguish authentic human emotions without being empathic.

Several recent studies have investigated how dogs perceive human emotional expressions. They have measured the reactions of dogs when exposed to stimuli presented in different modalities, such as photographs, audio recordings or odor samples, or to humans simulating various emotional situations. In the current study, dog owners were manipulated to genuinely experience emotions of happiness, sadness, and neutrality.

Predictors of distant metastatic recurrence in head and neck cutaneous squamous cell carcinoma with lymph node metastases treated with curative intent: A multicenter study.

Background: We aimed to identify predictors of distant metastatic recurrence (DMR) in patients with head and neck cutaneous squamous cell carcinoma (HNcSCC) with nodal metastases treated with curative intent.

Methods: Predictors of DMR were identified using Cox regression in a multicenter study of 1151 patients.

Results: The 5-year risk of DMR was 9.

Allocation Rules and Age-Dependent Waiting Times for Kidney Transplantation.

Background: Rigid age limits in the current allocation system for post-mortem donor kidneys in Germany may have problematic effects. The new German national transplantion registry enables data analysis with respect to this question.

Methods: Using anonymized data from the German national transplantion registry, we extracted and evaluated information on the recipients and postmortem donors of kidneys that were allocated in Germany through Eurotransplant over the period 2006-2020.

Concurrent optogenetic motor mapping of multiple limbs in awake mice reveals cortical organization of coordinated movements.

Background: Motor mapping allows for determining the macroscopic organization of motor circuits and corresponding motor movement representations on the cortex.

Computational modeling of heart failure in microgravity transitions.

The space tourism industry is growing due to advances in rocket technology. Privatised space travel exposes non-professional astronauts with health profiles comprising underlying conditions to microgravity. Prior research has typically focused on the effects of microgravity on human physiology in healthy astronauts, and little is known how the effects of microgravity may play out in the pathophysiology of underlying medical conditions, such as heart failure.

[Which dialysis method for whom? In-center dialysis vs home dialysis].

There are various dialysis methods available to treat patients with chronic kidney failure. Generally, a distinction is made between peritoneal dialysis and hemodialysis, as well as between home dialysis methods and center-based dialysis methods. To be able to advise patients optimally, it is important to understand the opportunities and limitations of the different method variants.

Unveiling the Unlikely: Extraskeletal Ewing Sarcoma Masquerading as Gastrointestinal Bleeding.

While Ewing sarcoma is traditionally a malignant tumor of bone, it may uncommonly present extra-skeletally, leading to an array of puzzling presentations depending on the tissue involved. Here, we describe the case of a 66-year-old man who presented to the primary care office for evaluation of intermittent melena. He ultimately underwent capsule endoscopy and developed a secondary small bowel obstruction, unveiling his neoplasm.

Aspirin resistance in patients with ventricular assist devices: A follow-up study.

Background: Despite combined anticoagulation therapy consisting of a vitamin K antagonist and an antiplatelet agent, thromboembolic complications often occur in patients with a left ventricular assist device (LVAD). In addition, bleeding events are also common. Resistance to antiplatelet drugs is a well-known phenomenon; however, the utilization of laboratory chemistry testing for the presence of such resistance, and then switching therapy, is controversial.

In a novel autoimmune and high-pressure glaucoma model a complex immune response is induced.

Background: The neurodegenerative processes leading to glaucoma are complex. In addition to elevated intraocular pressure (IOP), an involvement of immunological mechanisms is most likely. In the new multifactorial glaucoma model, a combination of high IOP and optic nerve antigen (ONA) immunization leads to an enhanced loss of retinal ganglion cells accompanied by a higher number of microglia/macrophages in the inner retina.

The Intersectoral Coordination Unit for the Sustainable Intensification of Peritoneal Dialysis in Schleswig-Holstein (SKIP-SH) cohort study.

Background: Peritoneal dialysis (PD) remains underutilised in Germany, prompting the initiation of the Sustainable Intensification of Peritoneal Dialysis in Schleswig-Holstein (SKIP-SH) project. The SKIP-SH cohort study aims to demonstrate the presumed benefits of PD, including enhanced quality of life and reduced healthcare personnel requirements, and to generate data to strengthen the use of PD.

Methods: The prospective SKIP-SH cohort study recruits patients with advanced chronic kidney disease (CKD) and their caregivers.

Recapitulation of human pathophysiology and identification of forensic biomarkers in a translational model of chlorine inhalation injury.

Chlorine gas (Cl) has been repeatedly used as a chemical weapon, first in World War I and most recently in Syria. Life-threatening Cl exposures frequently occur in domestic and occupational environments, and in transportation accidents. Modeling the human etiology of Cl-induced acute lung injury (ALI), forensic biomarkers, and targeted countermeasures development have been hampered by inadequate large animal models.

Potential and Uncertainties of RejectClass in Acute Kidney Graft Dysfunction: An Independent Validation Study.

Background: Kidney graft rejections are classified based on the Banff classification. The RejectClass algorithm, initially derived from a cohort comprising mostly protocol biopsies, identifies data-driven phenotypes of acute rejection and chronic pathology using Banff lesion scores. It also provides composite scores for inflammation activity and chronicity.

Occurrence of multiple fistulas decades after ingestion and neglect of numerous thermometers: a case report.

Background: Ingestion of thermometers is a very rare occurrence and associated with penetrations of hollow organs. An event decades ago can lead to the development of fistulas.

Case Presentation: We present a case of a 62-year-old male who swallowed multiple thermometers with a length of up to 22 cm over a period of 40 years.

The German Transplantation Registry Reveals Deficiencies in the Listing Process for Kidney Transplantation.

Introduction: The time from dialysis onset to enrollment on the kidney waiting list (listing time) is a crucial step on the path to receiving a kidney allograft; however, this process has received very little research attention in the Eurotransplant (ET) area.

Methods: We retrospectively analyzed data from the German transplantation registry, including patients who were on the waiting list for a first kidney transplant in Germany between 2006 and 2016. Listing time was evaluated using a mixed linear model.
