In elderly survivors, fewer factors had a positive (adequate physical exercise) or inverse (multimodality cancer treatment and current smoking) association with influenza vaccination.
 
  Influenza vaccination rate was suboptimal, especially among younger cancer survivors. Targeted strategies are necessary to improve influenza vaccination in cancer survivors with consideration of individual characteristics such as age, lifestyle, cancer treatment modality, cancer type and education level.

  To analyze global left ventricular longitudinal strain (GLS), mechanical dispersion (MD), electrocardiographic repolarization, and myocardial injury markers changes during androgen deprivation therapy (ADT) and subsequent hypogonadism in men with advanced prostate cancer.
 
  We included 31 patients 69.7±7.3years old, in sinus rhythm, with stable cardiac conditions and evaluated them by echocardiography, electrocardiography, and blood sampling for high sensitivity cardiac troponin I (hs-cTnI), and N-terminal pro-brain natriuretic peptide (NTproBNP), at ADT initiation (M0) and after 6months of treatment (M1). Peak longitudinal strain by speckle-tracking echocardiography was assessed in 17 left ventricular segments and averaged to GLS. Standard deviation of time intervals from the start of Q/R on electrocardiogram to peak longitudinal strain in the 17 segments (MD
  ), and the difference between the longest and shortest time-to-peak strain intervals (MD
  ) were calculated as indices of MD. Fridericia correctedphic repolarization parameters, and hs-cTnI during the first 6 months of treatment.The Western Cape province was the early epicentre of the coronavirus disease 2019 pandemic in South Africa and on the African continent. In this short article we report on an initiative set up within the provincial Department of Health early in the pandemic to facilitate collective learning and support for health workers and managers across the health system, emphasising the importance of leadership, systems resilience, nonhierarchical learning and connectedness. These strategies included regular and systematic engagement with organised labour, different ways of gauging and responding to staff morale, and daily 'huddles' for raid learning and responsive action. We propose three transformational actions that could deliver health systems that protect staff during good times and in times of system shocks. (a) Continuously invest in building the foundations of system resilience in good times, to draw on in an acute crisis situation.  https://www.selleckchem.com/products/retatrutide.html  (b) Provide consistent leadership for an explicit commitment to supporting health workers through decisive action across the system. (c) Optimise available resources and partners, act on improvement ideas and obstacles. Build trusting relationships amongst and across actors.
  The use of intraoperative indocyanine green (ICG) angiography has been well documented for confirmation of arterial perfusion in transferred free flaps. However, no previous report has yet focused on whether ICG angiography can be used to detect congestion in free flaps. The present report investigates the feasibility of ICG angiography for detecting flap congestion intraoperatively through illustrative cases.
 
  From September 2019 to September 2020, 65 consecutive female patients who underwent breast reconstructions using a free deep inferior epigastric perforator (DIEP) flap were enrolled in this study. Forty-eight patients with 52 DIEP flaps were eligible for the study after application of the exclusion criteria. ICG angiography was performed after elevation of the flap, after completion of the anastomoses, and after inset of the flap.
 
  In five cases (9.6%), an inadequate highlight was demonstrated with ICG angiography performed after flap elevation. All such cases were deemed congestive since robust bleeding was observed with the prick test. ICG angiography demonstrated sufficient highlight of the flap after removal of the clamp on the superficial inferior epigastric vein. In two cases (4.2%), kinking of the pedicle vein of the DIEP flap was found with ICG angiography performed after inset of the flap. In both cases, the pedicle and the flap were reinset. All flaps survived completely postoperatively.
 
  ICG angiography can detect flap congestion, and the proposed 3-step protocol is useful for the prevention of postoperative complications.

Majority of the PARP inhibitors are not isoform-selective which may cause unwanted off-target effects. In the present study, we explore the molecular mechanism and energy requirements for PARP-2 inhibition. This involves docking studies, frontier molecular orbital analysis, 500 ns molecular dynamics simulation (MD), binding free energy analysis and principal component analysis. The results clearly suggest the importance of hydrogen bonding (Gly429, Gln332, Ser470, Tyr455) and π-π stacking interactions (His428, Tyr455, Tyr462, Phe463, Tyr473) between residues and the inhibitor. Presence of lowest unoccupied molecular orbitals favors π-π stacking interactions and highest occupied molecular orbital orbital favors hydrogen-bonding interactions in the ligands. The stability of most active/PARP-2 complex is confirmed by hydrogen bonding and π-π stacking interaction parameters. Molecular-mechanics Poisson-Boltzmann surface area energy calculations showed that van der Waals and nonpolar solvation energy terms are crucial components for the stable binding of the ligands. Per residue analysis showed that tyrosine, histidine, and phenyl alanine residues are responsible for hydrophobic interactions with the ligands. Four new inhibitors are designed based on this study and the stability of PARP-2/inhibitor complex is validated by MD, density functional theory studies, and ADME/toxicity properties. Information from the present study can serve as a basis for designing new isoform-selective PARP-2 inhibitors.
