ely needed to determine the utility of NIRS.

NIRS has low sensitivity and high specificity to identify intra-operative ischaemia compared with awake monitoring. Extracranial signal contribution was highly variable. Ultimately, data from high quality studies are desperately needed to determine the utility of NIRS.

Postoperative pneumonia is a major cause of morbidity and mortality following cardiac surgery. The inflammatory response to cardiac surgery has been widely studied, but specific mechanisms for postoperative pneumonia have not been determined. Tranexamic acid is renowned for its effect on bleeding but can also modulate inflammatory processes. Cardiac surgery is known to release mitochondrial DAMPs (mtDAMPs) and is linked to postoperative inflammation and atrial fibrillation. We speculated that mtDAMPs might be related to postoperative pneumonia and that this might be modulated by tranexamic acid.

Forty-one (41) patients from the Aspirin and Tranexamic Acid for Coronary Artery Surgery (ATACAS) trial were studied. Levels of mitochondrial DNA, matrix metallopeptidase 9 (MMP-9) and neutrophil elastase (NE) were determined in plasma preoperatively, at 24 and 72 hours post-surgery and correlated with clinical outcome.

mtDNA was significantly elevated postoperatively in the placebo and tranexamic acid (TXA) groe low number of individuals developing pneumonia, further studies are warranted to clearly identify whether TXA impacts on the inflammatory response in postoperative pneumonia.

To investigate the effects of a 12-week early moderate-intensity resistance training program compared to aerobic-based rehabilitation on postoperative cognitive recovery following cardiac surgery via median sternotomy.

This was a multicentre, prospective, pragmatic, non-blinded, pilot randomised controlled trial (11 randomisation) of two parallel groups that compared a 12-week early moderate-intensity resistance training group to a control group, receiving aerobic-based rehabilitation. English-speaking adults (≥18 years) undergoing elective cardiac surgery via median sternotomy were randomised using sealed envelopes, with allocation revealed before surgery. The primary outcome was cognitive function, assessed using the Alzheimer's Disease Assessment Scale-cognitive subscale (ADAS-cog), at baseline, 14 weeks and 6 months postoperatively.

The ADAS-cog score at 14 weeks was significantly better for the resistance training group (n=14, 7.2±1.4; 95% CI 4.3, 10.2, vs n=17, 9.2±1.3; 95% CI 6.6, 11.9, p=0.010). At 14 weeks postoperatively, 53% of the aerobic-based rehabilitation group (n=9/17) experienced cognitive decline by two points or more from baseline ADAS-cog score, compared to 0% of the resistance training group (n=0/14; p=0.001).

Early resistance training appears to be safe and may improve cognitive recovery compared to standard, aerobic-based rehabilitation following cardiac surgery via median sternotomy, however as this was a pilot study, the sample size was small and further research is needed to determine a causal relationship.

While most plant-pathogen interaction studies focus on pathogen effectors and their functions in suppressing plant immunity or interfering with normal cellular processes, other virulence factors likely also contribute. Here we highlight another important strategy used by pathogens to promote virulence secretion of mimics of host molecules, including peptides, phytohormones, and small RNAs, which play diverse roles in plant development and stress responses. Palbociclib in vitro Pathogen-secreted mimics hijack the host endogenous signaling pathways, thereby modulating host cellular functions to the benefit of the pathogen and promoting infection. Understanding the mechanisms of pathogen-secreted host mimics will expand our knowledge of host-pathogen coevolution and interactions, while providing new targets for plant disease control.Kidney organoid technology has led to a renaissance in kidney developmental biology. The complex underpinnings of mammalian kidney development have provided a framework for the generation of kidney cells and tissues from human pluripotent stem cells. Termed kidney organoids, these 3-dimensional structures contain kidney-specific cell types distributed similarly to in vivo architecture. The adult human kidney forms from the reciprocal induction of two disparate tissues, the metanephric mesenchyme (MM) and ureteric bud (UB), to form nephrons and collecting ducts, respectively. Although nephrons and collecting ducts are derived from the intermediate mesoderm (IM), their development deviates in time and space to impart distinctive inductive signaling for which separate differentiation protocols are required. Here we summarize the directed differentiation protocols which generate nephron kidney organoids and collecting duct kidney organoids, making note of similarities as much as differences. We discuss limitations of these present approaches and discuss future directions to improve kidney organoid technology, including a greater understanding of anterior IM and its derivatives to enable an improved differentiation protocol to collecting duct organoids for which historic and future developmental biology studies will be instrumental.

Urolift implant placement may be preferred to conventional endoscopic surgery for patients who wish to preserve their sexuality or for those who prefer a rapid post-operative recovery. The absence of general anaesthesia is an important element that reinforces the minimally invasive aspect of the procedure and improves the speed of recovery. The aim of this work was to report our preliminary experience of Urolift treatment under local anaesthesia.

A retrospective analysis was conducted including all patients treated with Urolift between 2017 and 2021 in our centre. Local anaesthesia was based on the instillation of 2 Xylocaine gels at 4°C into the urethra 15minutes before the procedure. The primary endpoint was the successful completion of the procedure without interruption due to pain or the need for any other form of anaesthesia or analgesia.

Twenty-seven patients were included with a median age of 65years and a prostate volume of 46mL. The International Prostate Symptom Score (IPSS) was 23. The first 3patients were operated on under general anaesthesia. Local anaesthesia was introduced from the fourth patient onwards. There was no recourse to other modalities of analgesia or anaesthesia or interruption of the procedure. The operating time was 10minutes and pain was assessed at 1 on a visual analogue scale. At 3months, the IPSS score was 9 (P=0.001).

This preliminary experience confirms the feasibility of placing the Urolift implant under local anaesthesia without any failure of the proposed management. The improvement in IPSS score was consistent with previously published clinical trials.

The Toxic Stress Schema (TSS) is an ecological framework with a social justice lens for identifying and alleviating stress and strengthening social determinants of health for children and families of color impacted by the COVID-19 pandemic and the cumulative effects of racism and generational, systemic inequities.

Relevant literature is reviewed, and examples were provided to illustrate the differential impacts of the "stress superstorm" of 2020 had on children of color based on their family's position on the advantage-disadvantage continuum.

The utility of the TSS framework as a model for advanced nursing practice is demonstrated, and recommendations are formulated for the pediatric nurse practitioner's role in health policy.

The COVID-19 pandemic elucidated the historical inequities experienced by children and families of color. The TSS framework provides a model for recognizing, organizing, and implementing.

Patients presenting with mandibular prognathism and scheduled for orthognathic surgery were randomized into either the SSRO group or the IVRO group. Changes at B-point were assessed by serial tracing of lateral cephalograms, which were taken preoperatively, and at 2 weeks, 6 months, 1 year, and 2 years postoperatively. Ninety-eight patients were recruited, with 49 patients in each group. Between 2 weeks and 6 months postoperatively, there was significantly more surgical relapse in the horizontal direction (anterior movement) in the SSRO group when compared with the IVRO group (1.83 mm (SD 2.91 mm) vs 0.49 mm (SD 2.32 mm); p = 0.019). At 2 years, there was more surgical relapse in the horizontal direction in the SSRO group than in the IVRO group (0.27 mm (SD 0.34 mm) vs 0.10 mm (SD 0.29 mm); p = 0.014). There were also more absolute changes (irrespective of direction) at B-point in the SSRO group than in the IVRO group at postoperative 6 months, 1 year, and 2 years (p = 0.016, 0.049, and 0.045, respectively). The amounts of change at B-point as percentages of total mandibular setback were 1.3% and 3.5% in the IVRO group and SSRO group, respectively. There were no differences in vertical changes between the two groups at any time points. In conclusion, the horizontal stability at B-point was shown to be superior in the IVRO group compared with the SSRO group in the correction of mandibular prognathism during the 2-year follow-up. Although the exact clinical importance of this difference is unknown at this time, this possible benefit may be an important key factor when deciding which osteotomy technique to employ for mandibular setback.

Immune-related adverse events (irAEs) remain generally unpredictable, and severe irAEs remain challenging to detect early and manage. Very severe (grade IV-V) irAEs have not been extensively characterised in prospective studies, and their predictive factors remain unknown.

The objective of the study was to describe and identify predictive factors of very severe (grade IV-V) irAEs.

The French Registre des Effets Indésirables Sévères des Anticorps Monoclonaux Immunomodulateurs en Cancérologie (REISAMIC) registry has prospectively collected all clinically significant irAEs occurring in patients treated with immune checkpoint inhibitorsat Gustave Roussy Institute since 2014.

This was a single-centre prospective cohort study at the Gustave Roussy Institute cancer centre (Villejuif, France).

The participants were all adult patients with a solid or haematological cancer treated with an anti-programmed cell death 1 (PD-1) or an anti-programmed cell death-ligand 1 (PD-L1) and who presented a clinically significant irAE.
