Impact of COVID-19 pandemic and diabetes on mechanical reperfusion in patients with STEMI: insights from the ISACS STEMI COVID 19 Registry.

Background: It has been suggested the COVID pandemic may have indirectly affected the treatment and outcome of STEMI patients, by avoidance or significant delays in contacting the emergency system. No data have been reported on the impact of diabetes on treatment and outcome of STEMI patients, that was therefore the aim of the current subanalysis conducted in patients included in the International Study on Acute Coronary Syndromes-ST Elevation Myocardial Infarction (ISACS-STEMI) COVID-19.

Methods: The ISACS-STEMI COVID-19 is a retrospective registry performed in European centers with an annual volume of > 120 primary percutaneous coronary intervention (PCI) and assessed STEMI patients, treated with primary PCI during the same periods of the years 2019 versus 2020 (March and April).

Impact of COVID-19 Pandemic on Mechanical Reperfusion for Patients With STEMI.

Background: The fear of contagion during the coronavirus disease-2019 (COVID-19) pandemic may have potentially refrained patients with ST-segment elevation myocardial infarction (STEMI) from accessing the emergency system, with subsequent impact on mortality.

Objectives: The ISACS-STEMI COVID-19 registry aims to estimate the true impact of the COVID-19 pandemic on the treatment and outcome of patients with STEMI treated by primary percutaneous coronary intervention (PPCI), with identification of "at-risk" patient cohorts for failure to present or delays to treatment.

Methods: This retrospective registry was performed in European high-volume PPCI centers and assessed patients with STEMI treated with PPPCI in March/April 2019 and 2020.

Lenalidomide Maintenance with or without Prednisone in Newly Diagnosed Myeloma Patients: A Pooled Analysis.

We conducted a pooled analysis of two phase III trials, RV-MM-EMN-441 and EMN01, to compare maintenance with lenalidomide-prednisone vs. lenalidomide in newly diagnosed transplant-eligible and -ineligible myeloma patients. Primary endpoints were progression-free survival, progression-free survival 2 and overall survival with both regimens.

Loss of Fbxw7 synergizes with activated Akt signaling to promote c-Myc dependent cholangiocarcinogenesis.

Background & Aims: The ubiquitin ligase F-box and WD repeat domain-containing 7 (FBXW7) is recognized as a tumor suppressor in many cancer types due to its ability to promote the degradation of numerous oncogenic target proteins. Herein, we aimed to elucidate its role in intrahepatic cholangiocarcinoma (iCCA).

Methods: Herein, we first confirmed that FBXW7 gene expression was reduced in human iCCA specimens.

Complete and Durable Response to Combined Chemo/Radiation Therapy in Wild-Type Lung Adenocarcinoma with Diffuse Brain Metastases.

Most non-small-cell lung cancer (NSCLC) patients are likely to develop brain metastases during the course of their illness. Currently, no consensus on NSCLC patients' treatment with brain metastasis has been established. Although whole brain radiotherapy prolongs the median survival time of approximately 4 months, a cisplatin-pemetrexed combination may also represent a potential option in the treatment of asymptomatic NSCLC patients with brain metastases.

Cardiac Abnormalities in Alzheimer Disease: Clinical Relevance Beyond Pathophysiological Rationale and Instrumental Findings?

Objectives: This case control study sought to assess the presence and characteristics of cardiac abnormalities in patients with Alzheimer disease (AD).

Background: Protein misfolding is involved in the pathophysiology of neurodegenerative disorders such as AD. Recently, amyloid-beta (Aβ) aggregates were identified within the cardiomyocytes and interstitium of patients with AD, suggesting that Aβ oligomers may reach and damage the heart.

Combined CDK4/6 and Pan-mTOR Inhibition Is Synergistic Against Intrahepatic Cholangiocarcinoma.

Purpose: Intrahepatic cholangiocarcinoma (ICC) is an aggressive cancer type, lacking effective therapies and associated with a dismal prognosis. Palbociclib is a selective CDK4/6 inhibitor, which has been shown to suppress cell proliferation in many experimental cancer models. Recently, we demonstrated that pan-mTOR inhibitors, such as MLN0128, effectively induce apoptosis, although have limited efficacy in restraining proliferation of ICC cells.

[Dual antiplatelet therapy in elderly patients with acute coronary syndrome: does age make the difference?].

The appropriate use of dual antiplatelet therapy (DAPT) in elderly patients with acute coronary syndrome (ACS) remains a highly debated subject. In fact, achieving the correct balance between the reduction of ischemic risk and the increase in hemorrhagic events is more difficult in this population than in younger subjects, especially in the case of very potent drug therapy. As a consequence of this, despite guideline recommendations, antiplatelet therapy is currently underutilized in elderly patients with ACS.

DEXAMETHASONE IMPLANT FOR DIABETIC MACULAR EDEMA IN NAIVE COMPARED WITH REFRACTORY EYES: The International Retina Group Real-Life 24-Month Multicenter Study. The IRGREL-DEX Study.

Purpose: To investigate efficacy and safety of repeated dexamethasone (DEX) implants over 24 months, in diabetic macular edema (DME) eyes that were treatment naive compared with eyes refractory to anti-vascular endothelial growth factor treatment, in a real-life environment.

Methods: This multicenter international retrospective study assessed best-corrected visual acuity and central subfield thickness (CST) of naive and refractory eyes to anti-vascular endothelial growth factor injections treated with dexamethasone implants. Safety data (intraocular pressure rise and cataract surgery) were recorded.

Efficacy of MEK inhibition in a K-Ras-driven cholangiocarcinoma preclinical model.

Intrahepatic cholangiocarcinoma (iCCA) is a deadly malignancy with limited treatment options. Gain-of-function mutations in K-Ras is a very frequent alteration, occurring in ~15 to 25% of human iCCA patients. Here, we established a new iCCA model by expressing activated forms of Notch1 (NICD) and K-Ras (K-Ras) in the mouse liver (K-Ras/NICD mice).

Deregulated c-Myc requires a functional HSF1 for experimental and human hepatocarcinogenesis.

Deregulated activity of the c-Myc protooncogene is a frequent molecular event underlying mouse and human hepatocarcinogenesis. Nonetheless, the mechanisms sustaining c-Myc oncogenic activity in liver cancer remain scarcely delineated. Recently, we showed that the mammalian target of rapamycin complex 1 (mTORC1) cascade is induced and necessary for c-Myc dependent liver tumor development and progression.

A new mutation of the CDH1 gene in a patient with an aggressive signet-ring cell carcinoma of the stomach.

Germline mutations in CDH1, the gene coding for the E-cadherin adhesion protein, are known to cause hereditary diffuse gastric cancer. We identified a new truncating germline mutation (p.Asp538Thrfs*19) in exon 11 of the CDH1 gene in a 41-year-old male with a diffuse gastric cancer.

OCT Biomarkers as Functional Outcome Predictors in Diabetic Macular Edema Treated with Dexamethasone Implant.

Purpose: Identification and characterization of patients with diabetic macular edema (DME) are important for individualizing treatment and optimizing outcome. We investigated OCT biomarkers for DME treated by intravitreal dexamethasone (DEX) implant.

Design: Multicenter, retrospective, observational cohort study.

Pan-mTOR inhibitor MLN0128 is effective against intrahepatic cholangiocarcinoma in mice.

Background & Aims: Intrahepatic cholangiocarcinoma (ICC) is a lethal malignancy without effective treatment options. MLN0128, a second generation pan-mTOR inhibitor, shows efficacy for multiple tumor types. We evaluated the therapeutic potential of MLN0128 vs.

A functional mammalian target of rapamycin complex 1 signaling is indispensable for c-Myc-driven hepatocarcinogenesis.

Unlabelled: Amplification and/or activation of the c-Myc proto-oncogene is one of the leading genetic events along hepatocarcinogenesis. The oncogenic potential of c-Myc has been proven experimentally by the finding that its overexpression in the mouse liver triggers tumor formation. However, the molecular mechanism whereby c-Myc exerts its oncogenic activity in the liver remains poorly understood.

Plasmapheresis, Intravenous Immunoglobulins, and Autologous Serum Eyedrops in the Acute Eye Complications of Toxic Epidermal Necrolysis.

Purpose: Toxic epidermal necrolysis (TEN) is a rare, life-threatening, drug-induced, mucocutaneous disease, which can severely affect the ocular surface. The purpose of this study was to investigate the efficacy of plasmapheresis, human IV immunoglobulins (IVIg), and autologous serum (AS) eyedrops in the treatment of the severe acute ocular complications of TEN.

Methods: A retrospective chart review of all patients admitted to the Burn Unit, Azienda Ospedaliero-Universitaria-Sassari, Sassari, Italy, from 2009 to 2015, identified 9 patients (2 men, 7 women; mean age 63.

Jagged 1 is a major Notch ligand along cholangiocarcinoma development in mice and humans.

Intrahepatic cholangiocarcinoma (ICC) is a rare yet deadly malignancy with limited treatment options. Activation of the Notch signalling cascade has been implicated in cholangiocarcinogenesis. However, while several studies focused on the Notch receptors required for ICC development, little is known about the upstream inducers responsible for their activation.

Associations between ventilator settings during extracorporeal membrane oxygenation for refractory hypoxemia and outcome in patients with acute respiratory distress syndrome: a pooled individual patient data analysis : Mechanical ventilation during ECMO.

Purpose: Extracorporeal membrane oxygenation (ECMO) is a rescue therapy for patients with acute respiratory distress syndrome (ARDS). The aim of this study was to evaluate associations between ventilatory settings during ECMO for refractory hypoxemia and outcome in ARDS patients.

Methods: In this individual patient data meta-analysis of observational studies in adult ARDS patients receiving ECMO for refractory hypoxemia, a time-dependent frailty model was used to determine which ventilator settings in the first 3 days of ECMO had an independent association with in-hospital mortality.
