Background: Lung cancer (LC) causes more deaths worldwide than any other cancer type. Despite advances in therapeutic strategies, the fatality rate of LC cases remains high (95%) since the majority of patients are diagnosed at late stages when patient prognosis is poor. Analysis of the International Association for the Study of Lung Cancer (IASLC) database indicates that early diagnosis is significantly associated with favorable outcome.

Brain edema formation is a key factor for secondary tissue damage after traumatic brain injury (TBI), however, the type of brain edema and the temporal profile of edema formation are still unclear. We performed free water imaging, a bi-tensor model based diffusion MRI analysis, to characterize vasogenic brain edema (VBE) and cytotoxic edema (CBE) formation up to 7 days after experimental TBI. Male C57/Bl6 mice were subjected to controlled cortical impact (CCI) or sham surgery and investigated by MRI 4h, 1, 2, 3, 5, and 7 days thereafter ( = 8/group).

WNT enhancing signals in pancreatic cancer are transmitted by LGR6.

Aging (Albany NY)

September 2023

Department of General, Visceral and Transplantation Surgery, Hospital of the University of Munich, Ludwig-Maximilians-University (LMU), Munich, Bavaria, Germany.

The G-protein-coupled receptor LGR6 associates with ligands of the R-Spondin (RSPO) family to potentiate preexisting signals of the canonical WNT pathway. However, its importance in pancreatic ductal adenocarcinoma (PDAC) remains unclear. Here, we show that LGR6 is differentially expressed in various PDAC cell lines of mesenchymal and epithelial phenotype, respectively, siding with the latter subsets.

Background & Aims: Early identification of patients at risk for malnutrition followed by individualized nutrition interventions is a central step to the provision of appropriate nutrition care. However, a health care professional (HCP)-based nutrition screening is not always consistently integrated into routine care. Patient-reported (PR) nutrition screening could thus potentially alleviate the burden on the HCPs and contribute to a greater number of patients who are identified and treated for malnutrition.

Background: Multiple randomized trials have established adjuvant endocrine therapy (ET) and whole breast irradiation (WBI) as the standard approach after breast-conserving surgery (BCS) in early-stage breast cancer. The omission of WBI has been studied in multiple trials and resulted in reduced local control with maintained survival rates and has therefore been adapted as a treatment option in selected patients in several guidelines. Omitting ET instead of WBI might also be a valuable option as both treatments have distinctly different side effect profiles.

Despite progress in the development of anti-seizure medications (ASMs), one third of people with epilepsy have drug-resistant epilepsy (DRE). The working definition of DRE, proposed by the International League Against Epilepsy (ILAE) in 2010, helped identify individuals who might benefit from presurgical evaluation early on. As the incidence of DRE remains high, the TASK1 workgroup on DRE of the ILAE/American Epilepsy Society (AES) Joint Translational Task Force discussed the heterogeneity and complexity of its presentation and mechanisms, the confounders in drawing mechanistic insights when testing treatment responses, and barriers in modeling DRE across the lifespan and translating across species.

Article Synopsis
  • The study investigates the role of CCR2, a receptor for CCL2 involved in monocyte movement, in the risk of atherosclerotic cardiovascular disease, particularly through examining genetic variants in a large population sample from the UK Biobank.
  • Researchers identified 45 harmful genetic variants linked to lower monocyte counts, finding that carriers had a reduced risk of myocardial infarction and coronary artery disease, especially the M249K variant.
  • The M249K variant was associated with significantly lower risks for heart issues without increasing infection risk, suggesting its potential protective role against cardiovascular diseases.

Article Synopsis
  • Clopidogrel is an antiplatelet medication used to prevent cardiovascular diseases, but its effectiveness can vary based on genetic factors and clinical characteristics measured by the ABCD-GENE score.
  • A study analyzed data from 11,248 clopidogrel users in the UK Biobank, finding that a higher ABCD-GENE score indicated a greater risk of vascular events like heart attacks and strokes.
  • The results highlight that the ABCD-GENE score can predict vascular risks not only for clopidogrel users but also for those taking aspirin or not using either medication.

Non-melanoma skin cancer (NMSC) is the most common cancer in Caucasians worldwide. We investigated the pathophysiological role of MIF and its homolog D-DT in UVB- and chemically induced NMSC using Mif, D-dt and Mif/D-dt mice on a hairless SKH1 background. Knockout of both cytokines showed similar attenuating effects on inflammation after acute UVB irradiation and tumor formation during chronic UVB irradiation, without additive protective effects noted in double knockout mice, indicating that both cytokines activate a similar signaling threshold.

Aims: Arrhythmogenic cardiomyopathy (AC) is a severe heart disease predisposing to ventricular arrhythmias and sudden cardiac death caused by mutations affecting intercalated disc (ICD) proteins and aggravated by physical exercise. Recently, autoantibodies targeting ICD proteins, including the desmosomal cadherin desmoglein 2 (DSG2), were reported in AC patients and were considered relevant for disease development and progression, particularly in patients without underlying pathogenic mutations. However, it is unclear at present whether these autoantibodies are pathogenic and by which mechanisms show specificity for DSG2 and thus can be used as a diagnostic tool.
