[Development and Implementation of a Nutrition Medicine Strategy to optimize Medical Service for Malnourished Patients at a Tertiary Referral Centre].

Zentralbl Chir 2021 Jun 21;146(3):283-295. Epub 2021 Jun 21.

Klinik und Poliklinik für Allgemein-, Viszeral-, Thorax- und Gefäßchirurgie, Universitätsklinikum Bonn, Deutschland.

Background: Malnutrition in hospitalised patients is an important and underestimated problem, with a negative impact on outcome and survival - not only in surgical patients. There is a discrepancy between optimal treatment as defined in relevant guidelines on clinical nutrition and the clinical reality. The Main reason for this discrepancy is the lack of established structures for nutrition medicine as an integral part of clinical routines. Read More

[Background, Necessity and Methodology of the S3 Guideline "Perioperative Management of Gastrointestinal Tumours (POMGAT)"].

Zentralbl Chir 2021 Jun 21;146(3):241-248. Epub 2021 Jun 21.

Klinik und Poliklinik für Allgemein-, Viszeral-, Thorax- und Gefäßchirurgie, Universitätsklinikum Bonn, Deutschland.

Malignancies are among the most common diseases, especially in old age, and are responsible for 25% of all deaths in Germany. Especially carcinomas of the gastrointestinal tract can be cured in most cases only through extensive surgery with significant morbidity. About 25 years ago, the multimodal, perioperative Fast Track (FT) concept for reducing postoperative complications was introduced and additional elements were added in the following years. Read More

Impact of COVID-19 on healthcare organisation and cancer outcomes.

Eur J Cancer 2021 May 28;153:123-132. Epub 2021 May 28.

Department of Biostatistics and Epidemiology, Gustave Roussy, Paris-Saclay University, Villejuif, France; Oncostat U1018, Inserm, Paris-Saclay University, Labeled Ligue Contre le Cancer, Villejuif, France.

Background: Changes in the management of patients with cancer and delays in treatment delivery during the COVID-19 pandemic may impact the use of hospital resources and cancer mortality.

Patients And Methods: Patient flows, patient pathways and use of hospital resources during the pandemic were simulated using a discrete event simulation model and patient-level data from a large French comprehensive cancer centre's discharge database, considering two scenarios of delays: massive return of patients from November 2020 (early-return) or March 2021 (late-return). Expected additional cancer deaths at 5 years and mortality rate were estimated using individual hazard ratios based on literature. Read More

Differential effects of acute cerebellectomy on cough in spontaneously breathing cats.

PLoS One 2021 21;16(6):e0253060. Epub 2021 Jun 21.

Department of Physiological Sciences, College of Veterinary Medicine, University of Florida, Gainesville, Florida, United States of America.

The role of the cerebellum in controlling the cough motor pattern is not well understood. We hypothesized that cerebellectomy would disinhibit motor drive to respiratory muscles during cough. Cough was induced by mechanical stimulation of the tracheobronchial airways in anesthetized, spontaneously breathing adult cats (8 male, 1 female), and electromyograms (EMGs) were recorded from upper airway, chest wall, and abdominal respiratory muscles.

Automatic assessment of Pectus Excavatum severity from CT images using deep learning.

IEEE J Biomed Health Inform 2021 Jun 21;PP. Epub 2021 Jun 21.

Pectus excavatum (PE) is the most common abnormality of the thoracic cage, whose severity is evaluated by extracting three indices (Haller, correction and asymmetry) from computed tomography (CT) images. To date, this analysis is performed manually, which is tedious and prone to variability. In this paper, a fully automatic framework for PE severity quantification from CT images is proposed, comprising three steps: (1) identification of the sternue's greatest depression point; (2) detection of 8 anatomical keypoints relevant for severity assessment; and (3) measurements' geometric regularization and extraction.

Artif Organs 2021 Jun 21. Epub 2021 Jun 21.

Department of Anesthesia and Intensive Care, IRCCS ISMETT, UPMC Italy, Palermo, Italy.

ECMO is frequently used in many centers around the globe for various indications. However, prognosis is often poor even with all supportive therapies, and in many cases clinical deterioration is associated with inflammation. Hemoadsorption with CytoSorb is a novel approach to limit the inflammatory response, and the device can be safely and easily installed into ECMO circuits. Read More

The effect of perioperative hemadsorption in patients operated for acute infective endocarditis - A randomized, controlled study.

Artif Organs 2021 Jun 21. Epub 2021 Jun 21.

Department of Thoracic- and Cardiovascular Surgery, University Hospital, Georg-August-University, Robert Koch Strasse 40, 37075, Göttingen, Germany.

Objectives: Patients operated for infective endocarditis (IE) are at high risk of developing an excessive systemic hyper-inflammatory state, resulting in systemic inflammatory response syndrome (SIRS) and septic shock. Hemadsorption (HA) by cytokine adsorbers has been successfully applied to remove inflammatory mediators. This randomized controlled trial investigates the effect of perioperative HA therapy on inflammatory parameters and hemodynamic status in patients operated for IE. Read More

Oncogenic potential of human pluripotent stem cell-derived lung organoids with HER2 overexpression.

Int J Cancer 2021 Jun 21. Epub 2021 Jun 21.

Department of Regenerative Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama, Japan.

Lung adenocarcinoma (LUAD) is the most common types among lung cancers generally arising from terminal airway and understanding of multistep carcinogenesis is crucial to develop novel therapeutic strategy for LUAD. Here we used human induced pluripotent stem cells (hiPSCs) to establish iHER2-hiPSCs in which doxycycline induced the expression of the oncoprotein HER2/ERBB2. Lung progenitors that differentiated from iHER2-hiPSCs, which expressed NKX2-1/TTF-1 known as a lung lineage maker, were cocultured with human fetal fibroblast and formed Human lung organoids (HLOs) comprising alveolar type 2-like cells.

Screening and clinical significance of lymph node metastasis-related genes within esophagogastric junction adenocarcinoma.

Cancer Med 2021 Jun 21. Epub 2021 Jun 21.

Department of Thoracic Surgery, Shandong Provincial Hospital Affiliated to Shandong First Medical University, Shandong Province, P. R. China.

Background: Despite recent improvements in treatment technologies, such as surgical resection and chemoradiotherapy, the prognosis of patients with esophagogastric junction adenocarcinoma (EJA) remains poor due to early lymph node metastasis. Since few studies have investigated genes associated with lymph node metastasis in EJA, we aimed to screen lymph node metastasis-associated genes and clarify their expression status and prognostic significance in EJA.

Methods: The differential frequency of mutations between carcinoma and para-carcinoma tissues from 199 cases with EJA was detected using targeted next-generation sequencing (tNGS). Read More

The causal effects of serum lipids and apolipoproteins on kidney function: multivariable and bidirectional Mendelian-randomization analyses.

Int J Epidemiol 2021 Jun 21. Epub 2021 Jun 21.

K.G. Jebsen Center for Genetic Epidemiology, Department of Public Health and Nursing, NTNU, Norwegian University of Science and Technology, Trondheim, Norway.

Background: The causal nature of the observed associations between serum lipids and apolipoproteins and kidney function are unclear.

Methods: Using two-sample and multivariable Mendelian randomization (MR), we examined the causal effects of serum lipids and apolipoproteins on kidney function, indicated by the glomerular-filtration rate estimated using creatinine (eGFRcrea) or cystatin C (eGFRcys) and the urinary albumin-to-creatinine ratio (UACR). We obtained lipid- and apolipoprotein-associated genetic variants from the Global Lipids Genetics Consortium (n = 331 368) and UK Biobank (n = 441 016), respectively, and kidney-function markers from the Trøndelag Health Study (HUNT; n = 69 736) and UK Biobank (n = 464 207).
