To explore the possible way of proline-serine-threonine phosphatase-interacting protein 2 (PSTPIP2) influencing diabetes mellitus-osteoarthritis (DM-OA) progression.

In vivo, eight-week-old male Sprague Dawley rats were induced with DM-OA by intraperitoneal injection of streptozotocin with high-fat diet feeding and intra-articular injection of monoiodoacetate. PSTPIP2 overexpression was achieved by intra-articular injection of lentivirus vectors. PSTPIP2 expression was verified by real-time polymerase chain reaction and Western blotting. Histological changes were examined by hematoxylin/eosin and safranin-O/fast-green staining. In vitro, rat synovial fibroblasts were induced DM-OA by stimulation of high glucose (HG) and interleukin (IL)-1β. PSTPIP2 overexpression was achieved by lentivirus infection. U0126 was added as an ERK inhibitor. Levels of tumor necrosis factor (TNF)-α, IL-6, and IL-1β were detected using enzyme-linked immunosorbent assay. Expression of matrix metalloproteinase (MMP)-3, MMP-13, aggat synovial fibroblasts, PSTPIP2 protein expression was decreased compared to normal glucose (NG)-treated cells. Levels of TNF-α, IL-6, and IL-1β, as well as expression of MMP-3, MMP-13, ADAMTS-5, ICAM-1, ERK and p-ERK were increased. After cells were infected with PSTPIP2-overexpressed lentivirus, levels of TNF-α, IL-6, and IL-1β, and expression of MMP-3, MMP-13, ADAMTS-5, ICAM-1, ERK and p-ERK were obviously decreased compared to cells infected with NC lentivirus. In addition, ERK inhibitor U0126 treatment also decreased the TNF-α, IL-6, and IL-1βlevels and MMP-3, MMP-13, ADAMTS-5, ICAM-1, ERK and p-ERK expression in HG + IL-1β treated rat synovial fibroblasts.

Overexpression of PSTPIP2 alleviates synovial inflammation and cartilage injury during DM-OA progression via inhibiting ERK phosphorylation.

Osimertinib is a third-generation epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) approved for the treatment of patients with EGFR-mutant non-small cell lung cancer (NSCLC). However, the mechanisms of acquired drug resistance to osimertinib have not as yet been clarified. Exosomes and microRNAs (miRNAs) are involved in carcinogenesis and drug resistance in human cancers.

We used previously established osimertinib-resistant HCC827 (HCC827-OR) and PC-9 (PC-9-OR) cells. We evaluated the profiles of exosomal miRNA associated with resistance to osimertinib in EGFR-mutant NSCLC cells.

Epithelial-mesenchymal transition (EMT) phenomenon was observed in HCC827-OR and PC-9-OR cells. Microarray and quantitative reverse transcription-polymerase chain reaction analysis revealed that miR-210-3p was co-upregulated in exosomes isolated from HCC827-OR and PC-9-OR cells compared with those isolated from parental HCC827 and PC-9 cells. HCC827-OR cell-derived exosomes induced EMT changes and resistance to osimertinib in HCC827 cells. Subsequently, the induction of miR-210-3p directly promoted the EMT phenomenon and resistance to osimertinib in HCC827 cells.

Exosomal miR-210-3p may play a crucial role in resistance to osimertinib in the tumor microenvironment of EGFR-mutant NSCLC.

Visceral adipose tissue (AT) promotes inflammation and may be associated with disease progression in heart failure with preserved ejection fraction (HFpEF). We characterized regional AT distribution in HFpEF patients and controls and analysed associations with co-morbidities and exercise tolerance.

Magnetic resonance imaging was performed to quantify epicardial, liver, abdominal, and thigh skeletal muscle AT. We assessed New York Heart Association (NYHA) class, 6min walk distance, and global well-being score. Multivariable linear regression models adjusting for body surface area were used. We studied 55 HFpEF patients (41 women, mean age 67±11years) and 33 controls (21 women, mean age 57±10years). Epicardial AT (median [interquartile range] 4.6 [2.0] vs. 3.2 [1.4] mm, P<0.001), thigh intermuscular fat (11.0 [11.5] vs. 5.0 [2.7] cm

, P<0.001) and liver fat fraction (6.4% [6.1] vs. 4.1% [5.5], P=0.001) were higher in HFpEF patients than controls. Women with HFpEF had higher abdominal and thigh subcuents have increased epicardial, liver, and skeletal muscle fat compared with controls out of proportion to their increased body size, and adiposity was associated with worse NYHA class and exercise tolerance in HFpEF. These results provide the basis for further investigation into the effect of interventions to reduce regional AT distribution in relation to HFpEF symptoms and pathophysiology.

To determine the risk of patients with an early diagnosis of heritable retinoblastoma being diagnosed with TRb (or pineoblastoma) asynchronously in a later stage and its effect on screening.

We updated the search (PubMed and Embase) for published literature as performed by our research group in 2014 and 2019. Trilateral retinoblastoma (TRb) patients were eligible for inclusion if identifiable as unique and the age at which TRb was diagnosed was available. The search yielded 97 new studies. Three new studies and eight new patients were included. Combined with 189 patients from the previous meta-analysis, the database included 197 patients. The main outcome was the percentage of asynchronous TRb in patients diagnosed before and after preset age thresholds of 6 and 12months of age at retinoblastoma diagnosis.

Seventy-nine per cent of patients with pineoblastoma are diagnosed with retinoblastoma before the age of 12months. However, baseline MRI screening at time of retinoblastoma diagnosis fails to detect the later diagnosed pineal TRb in 89% of patients. K-Ras(G12C) inhibitor 9 We modelled that an additional MRI performed at the age of 29months picks up 53% of pineoblastomas in an asymptomatic phase. The detection rate increased to 72%, 87% and 92%, respectively, with 2, 3 and 4 additional MRIs.

An MRI of the brain in heritable retinoblastoma before the age of 12months misses most pineoblastomas, while retinoblastomas are diagnosed most often before the age of 12months. Optimally timed additional MRI scans of the brain can increase the asymptomatic detection rate of pineoblastoma.

Platelet indices have been associated with traditional cardiovascular risk factors, cardiovascular diseases and all-cause mortality. This study aimed to investigate the role of platelet count, mean platelet volume (MPV) and platelet-to-leukocyte ratio, including platelet-to-monocyte and platelet-to-lymphocyte ratio with cardiac function, heart failure (HF) phenotypes and clinical outcome, worsening of HF.

Univariate and multivariable linear and Cox regression analyses were used to investigate the associations between platelet indices, cardiac function and worsening of HF in 3250 subjects enrolled in the MyoVasc study. Higher MPV, lower platelet count, lower platelet-to-leukocyte and platelet-to-monocyte ratios have been associated with reduced left ventricular ejection fraction (beta estimate [β]

Platelet indices are linked with worse cardiac function and adverse clinical outcome, independent of subjects' underlying cardiovascular profile. This study emphasizes their important value to provide additional information on pathophysiology and risk stratification in HF syndrome.Nesfatin-1 (encoded by NUCB2) is a cardiac peptide possessing protective activities against myocardial ischaemia/reperfusion (MI/R) injury. However, the regulation of NUCB2/nesfatin-1 and the molecular mechanisms underlying its roles in MI/R injury are not clear. Here, by investigating a mouse MI/R injury model developed with transient myocardial ischaemia followed by reperfusion, we found that the levels of NUCB2 transcript and nesfatin-1 amount in the heart were both decreased, suggesting a transcriptional repression of NUCB2/nesfatin-1 in response to MI/R injury. Moreover, cardiac nesfatin-1 restoration reduced infarct size, troponin T (cTnT) level and myocardial apoptosis, supporting its cardioprotection against MI/R injury in vivo. Mechanistically, the Akt/ERK pathway was activated, and in contrast, endoplasmic reticulum (ER) stress was attenuated by nesfatin-1 following MI/R injury. In an in vitro system, similar results were obtained in nesfatin-1-treated H9c2 cardiomyocytes with hypoxia/reoxygenation (H/R) injury. More importantly, the treatment of wortmannin, an inhibitor of Akt/ERK pathway, abrogated nesfatin-1 effects on attenuating ER stress and H/R injury in H9c2 cells. Furthermore, nesfatin-1-mediated protection against H/R injury also vanished in the presence of tunicamycin (TM), an ER stress inducer. Lastly, Akt/ERK inhibition reversed nesfatin-1 effects on mouse ER stress and MI/R injury in vivo. Taken together, these findings demonstrate that NUCB2/nesfatin-1 inhibits MI/R injury through attenuating ER stress, which relies on Akt/ERK pathway activation. Hence, our study provides a molecular basis for understanding how NUCB2/nesfatin-1 reduces MI/R injury.We report on a 70-year-old woman who tried to eliminate ants from her kitchen by applying a publicly available insecticide spray. Immediately afterwards, she felt dyspnoea, superseded by heavy chest pain. High-sensitivity troponin concentration increased from 33 to 149 ng/L (cut-off 50 ng/L). Significant coronary stenosis was excluded by coronary angiography, and the myocardial damage was classified as myocardial infarction type II. After exclusion of other potential mechanisms, we consider a cardiotoxic effect of the insecticide mixture of cypermethrin, tetramethrin, and piperonyl butoxide possible. We conclude that consumer information has to be improved. This concerns sustainable control measures adapted to the target insect species (in this case, the black garden ant Lasius niger), and differentiation between authorized and non-authorized but notified products. The instructions for use should give clear information on vulnerable groups and recommend personal protective equipment. Physicians and authorities should be alert to cardiac side-effects of insecticides.

The study sought to investigate the long-term outcome after transcatheter mitral valve annuloplasty for secondary mitral regurgitation (MR).

Consecutive patients with symptomatic secondary MR undergoing transcatheter mitral valve annuloplasty with the Carillon device at Leipzig University Hospital between 2012 and 2018 were studied prospectively. Left ventricular (LV) function and MR severity were quantified by standardized echocardiography. 33 patients were included. Mean age was 75±10years, and 20 patients were women. A Society of Thoracic Surgeons score of 8.1±7.2% indicated high-risk status. In 24 patients, MR resulted from LV remodelling and dysfunction, eight suffered from left atrial dilatation, and one patient had MR due to combined primary and secondary aetiology. LV ejection fraction at baseline was (median) 38% [inter-quartile range (IQR) 30-49%]. During the mean follow-up time of 45±20months, 17 patients died, two patients withdraw consent, and four patients were lost. Of the remaining patients, four were hospitalized for decompensated heart failure.
