The prognosis of chronic heart failure with reduced ejection fraction (HFrEF) has been studied extensively, but factors predicting cardiac decompensation are poorly defined. Right ventricular stroke work index (RVSWI), an invasive measure of right ventricular (RV) systolic function, is a well-known prognostic marker of RV failure after left ventricular assist device insertion and after lung transplantation. Thus, the aim of this study was to assess whether there is a relationship between RVSWI, HFrEF hospital readmission due to cardiac decompensation, and prognosis.
 
  We prospectively enrolled 132 consecutive patients with HFrEF. Right heart catheterization was performed and RVSWI values were calculated in all patients. The relationship between RVSWI values and readmission and prognosis was analyzed.
 
  During a median follow-up of 20±7 months, 33 patients were readmitted due to cardiac decompensation in the survivor group, and 18 patients died due to cardiac causes. There was no difference between patients who died and survived in terms of RVSWI values. Among patients with decompensation, mean RVSWI was significantly lower than in patients with stable HFrEF (6.0±2.2 g/m
  /beat vs. 8.8±3.5 g/m
  /beat, p<0.001). On correlation analysis, RVSWI was negatively correlated with NYHA functional class. RVSWI was also identified as an independent risk factor for cardiac decompensation in Cox regression survival analysis.
 
  We showed that RVSWI predicts cardiac decompensation and correlates with functional class in advanced stage HFrEF. Our data suggest the value of combining information on right heart hemodynamics with assessment of RV function when defining the risk of patients with advanced HFrEF.

Despite the absence of significant coronary lesions, in the setting of a vulnerable substrate - a hypokinetic and hyperechogenic region of ventricular myocardium - an upgrade to a dual-chamber implantable cardioverter-defibrillator was performed, and substrate ablation was planned.Small ubiquitin-like modifiers (SUMOs) regulate virtually all nuclear processes. The fate of the target protein is determined by the architecture of the attached SUMO protein, which can be of polymeric nature. Here, we highlight the multifunctional aspects of dynamic signal transduction by SUMO polymers. The SUMO-targeted ubiquitin ligases (STUbLs) RING-finger protein 4 (RNF4) and RNF111 recognize SUMO polymers in a chain-architecture-dependent manner, leading to the formation of hybrid chains, which could enable proteasomal destruction of proteins. Recent publications have highlighted essential roles for SUMO chain disassembly by the mammalian SUMO proteases SENP6 and SENP7 and the yeast SUMO protease Ulp2. SENP6 is particularly important for centromere assembly. These recent findings demonstrate the diversity of SUMO polymer signal transduction for proteolytic and nonproteolytic purposes.
  This report describes why there is a need for cancer-specific physical activity and exercise prescription guidelines, how the recommendations in the guidelines were derived, and how these guidelines can be used and by whom, to reduce cancer-related burden.

  Higher physical activity levels post-cancer diagnosis has been consistently associated with improved morbidity and/or survival outcomes for all cancers studied to date. As such, although physical activity recommendations for those post-cancer are largely generic and tend to replicate physical activity guidelines endorsed for healthy adults, the cancer-specific epidemiological evidence-base suggest this to be appropriate. These guidelines should be endorsed and promoted by all members of the cancer care team, across all phases of cancer survivorship. Cancer-specific exercise prescription guidelines are supported by a clinical trial evidence-base and enable targeted exercise prescription for the benefit of the individual patient. Any member of the cancer care team can refer patients at any time to exercise professionals, who will use these exercise guidelines to direct their provision of exercise as medicine.
 
  The prevention of physical activity declines and small increases in physical activity levels during and following cancer treatment is appropriate for the majority. Further, physical activity promotion, alongside incorporation of planned, purposeful, targeted and individualized exercise, has significant potential for reducing morbidity and mortality of cancer worldwide.
 
  Nurses are well-placed to regularly encourage patients to participate in physical activity, and to refer patients to exercise professionals, during and following their cancer treatment.

  Exercise initiated in the early stages of cancer treatment may present as the most opportune time to reduce the detrimental side effects of treatment. Beginning exercise post-cancer treatment may not be early enough to elicit important improvements. The role of exercise alongside chemotherapy treatment, specifically during chemotherapy infusion may be an opportunity for the therapeutic delivery of exercise for cancer patients.

  Exercise initiated in the early stages of chemotherapy treatment may present as the most opportune time to improve therapeutic health outcomes and patient experience. If exercise during chemotherapy infusion could be feasible more testing is warranted to explore different modes including resistance-based exercise, dosage, intensity, and its potential affect on tumor hypoxia and chemotherapy drug uptake.
 
  Oncology nurses are in the ideal position to initiate the conversation about exercise during chemotherapy treatments specifically the opportunity to provide light exercise during chemotherapy infusion.
