These findings demonstrate that melanoma metastasis is driven by the AP-2alpha/EZH2 pathway and suggest that AP-2alpha expression can be used as a biomarker to predict responsiveness to EZH2 inhibitors for the treatment of advanced melanomas.Blood levels of acute-phase protein α1-acid glycoprotein (AGP, orosmucoid) increase in patients with cancer. Although AGP is produced from hepatocytes following stimulation by immune cell-derived cytokines under conditions of inflammation and tumorigenesis, the functions of AGP in tumorigenesis and tumor progression remain unknown. In the present study, we revealed that AGP contributes directly to tumor development by induction of programmed death ligand 1 (PD-L1) expression and IL-6 production in macrophages. Stimulation of AGP induced PD-L1 expression in both human monocyte-derived macrophages through STAT1 activation, whereas AGP had no direct effect on PD-L1 expression in tumor cells. AGP also induced IL-6 production from macrophages, which stimulated proliferation in tumor cells by IL-6R-mediated activation of STAT3. Furthermore, administration of AGP to AGP KO mice phenocopied effects of tumor-associated macrophages on tumor progression. AGP decreased IFN-γ secretion from T-cells and enhanced STAT3 activation in subcutaneous tumor tissues. In addition, AGP regulated PD-L1 expression and IL-6 production in macrophages by binding with CD14, a co-receptor for TLR4, and inducing TLR4 signaling. These results provide the first evidence that AGP is directly involved in tumorigenesis by interacting with tumor-associated macrophages and that AGP might be a target molecule for anti-cancer therapy.
Ibrutinib is a tyrosine kinase inhibitor most commonly associated with atrial fibrillation. However, additional cardiotoxicities have been identified, including accelerated hypertension. The incidence and risk factors of new or worsening hypertension following ibrutinib treatment are not as well known.

We conducted a retrospective study of 144 patients diagnosed with B cell malignancies treated with ibrutinib (n=93) versus conventional chemoimmunotherapy (n=51) and evaluated their effects on blood pressure at 1, 2, 3 and 6 months after treatment initiation. Descriptive statistics were used to compare baseline characteristics for each treatment group. Fisher's exact test was used to identify covariates significantly associated with the development of hypertension. Repeated measures analyses were conducted to analyse longitudinal blood pressure changes.

Both treatments had similar prevalence of baseline hypertension at 63.4% and 66.7%, respectively. There were no differences between treatments by age, sexologists must be aware of this cardiotoxicity to allow timely management of blood pressure elevations.
Ibrutinib is associated with the development of hypertension and worsening of blood pressure. Cardiologists and oncologists must be aware of this cardiotoxicity to allow timely management of blood pressure elevations.Cancer and cardiovascular disease share many risk factors. Due to improved survival of patients with cancer, the cohort of cancer survivors with heart failure referred for heart transplantation (HT) is growing. Specific considerations include time interval between cancer treatment and HT, risk for recurrence and risk for de novo malignancy (dnM). dnM is an important cause of post-HT morbidity and mortality, with nearly a third diagnosed with malignancy by 10 years post-HT. Compared with the age-matched general population, HT recipients have an approximately 2.5-fold to 4-fold increased risk of developing cancer. HT recipients with prior malignancy show variable cancer recurrence rates, depending on years in remission before HT 5% recurrence if >5 years in remission, 26% recurrence if 1-5 years in remission and 63% recurrence if less then 1 year in remission. A myriad of mechanisms influence oncogenesis following HT, including reduced host immunosurveillance from chronic immunosuppression, influence of oncogenic viruses, and the cumulative intensity and duration of immunosuppression. Conversely, protective factors include acyclovir prophylaxis, use of proliferation signal inhibitors (PSI) and female gender. Management involves reducing immunosuppression, incorporating a PSI for immunosuppression and heightened surveillance for allograft rejection. Cancer treatment, including immunotherapy, may be cardiotoxic and lead to graft failure or rejection. Additionally, there exists a competing risk to reduce immunosuppression to improve cancer outcomes, which may increase risk for rejection. A multidisciplinary cardio-oncology team approach is recommended to optimise care and should include an oncologist, transplant cardiologist, transplant pharmacist, palliative care, transplant coordinator and cardio-oncologist.We report the benign clinical course of a 'hand knob' stroke syndrome in a 106-year-old man and discuss some issues that arise when caring for the very oldest of the old.COVID-19 resulting from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has resulted in a pandemic of respiratory failure previously unencountered. Early in the pandemic, concentrated infections in high-density population cities threatened to overwhelm health systems, and ventilator shortages were predicted. An early proposed solution was the use of shared ventilation, or the use of a single ventilator to support ≥ 2 patients. Spurred by ill-conceived social media posts, the idea spread in the lay press. Prior to 2020, there were 7 publications on this topic. A year later, more than 40 publications have addressed the technical details for shared ventilation, clinical experience with shared ventilation, as well as the numerous limitations and ethics of the technique. This is a review of the literature regarding shared ventilation from peer-reviewed articles published in 2020.Postoperative pulmonary complications have a significant impact on perioperative morbidity and mortality and contribute substantially to health care costs. Surgical stress and anesthesia lead to changes in respiratory physiology, altering lung volumes, respiratory drive, and muscle function that can cumulatively increase the risk of postoperative pulmonary complications. Preoperative medical evaluation requires a structured approach to identify patient-, procedure-, and anesthesia-related risk factors for postoperative pulmonary complications. Bortezomib molecular weight Validated risk prediction models can be used for risk stratification and to help tailor the preoperative investigation. Optimization of pulmonary comorbidities, smoking cessation, and correction of anemia are risk-mitigation strategies. Lung-protective ventilation, moderate PEEP application, and conservative use of neuromuscular blocking drugs are intra-operative preventive strategies. Postoperative early mobilization, chest physiotherapy, oral care, and appropriate analgesia speed up recovery.
