Therapeutically exploiting STAT3 activity in cancer - using tissue repair as a road map.

Abstract: The tightly orchestrated temporal and spatial control of signal transducer and activator of transcription 3 (STAT3) activity in epithelial, immune and stromal cells is critical for wound healing and tissue repair. Excessive STAT3 activation within cancer cells and cells of the tumour microenvironment can be viewed as a neoplastic mimic of an inflammation-driven repair response that collectively promotes tumour progression. In addition to the canonical transcriptional pathways by which STAT3 promotes stem cell-like characteristics, survival, proliferation, metastatic potential and immune evasion, cytoplasmic STAT3 activity fuels tumour growth by metabolic and other non-transcriptional mechanisms. Here, we review the tumour-modulating activities of STAT3 in light of its role as a signalling node integrating inflammatory responses during wound healing. Accordingly, many of the cytokines that contribute to the para-inflammatory state of most solid malignancies converge on and underpin dysregulated STAT3 activity. Targeting of these cytokines, their cognate receptors and associated signalling cascades in clinical trials is beginning to demonstrate therapeutic efficacy, given that interference with STAT3 activity is likely to simultaneously curb the growth of cancer cells and augment antitumour immunity. This Review discusses how excessive signal transducer and activator of transcription 3 (STAT3) activation within cancer cells and cells of the tumour microenvironment can be viewed as a neoplastic mimic of an inflammation-driven repair response that promotes tumour progression.

Hospital discharge planning for frail older people and their family. Are we delivering best practice? A review of the evidence.

Abstract: Aims and objectives. This paper examined the available evidence concerning hospital discharge practices for frail older people and their family caregivers and what practices were most beneficial for this group. Background. Hospital discharge practices are placing an increasing burden of care on the family caregiver. Discharge planning and execution is significant for older patients where inadequate practices can be linked to adverse outcomes and an increased risk of readmission. Design. Literature review. Methods. A review of English language literature published after 1995 on hospital discharge of frail older people and family carer’s experiences. Results. Numerous factors impact on the hospital discharge planning of the frail older person and their family carer’s that when categorised focus on the role that discharge planning plays in bridging the gap between the care provided in hospital and the care needed in the community, its potential to reduce the length of hospital stay, the impact of the discharge process on family carer’s and the need for a coordinated health professional approach that includes dissemination of information, clear communication and active support. Conclusion. The current evidence indicates that hospital discharge planning for frail older people can be improved if interventions address family inclusion and education, communication between health care workers and family, interdisciplinary communication and ongoing support after discharge. Interventions should commence well before discharge. Relevance to clinical practice. An awareness of how the execution of the hospital discharge plan is perceived by the principal family carer of a frail older person, will allow nurses and others involved with the discharge process to better reconcile the family caregivers’ needs and expectations with the discharge process offered by their facility. The research shows there is a direct correlation between the quality of discharge planning and readmission to hospital.

2016 Patellofemoral pain consensus statement from the 4th International Patellofemoral Pain Research Retreat, Manchester. Part 1: Terminology, definitions, clinical examination, natural history, patellofemoral osteoarthritis and patient-reported outcome measures

Abstract: Patellofemoral pain (PFP) typically presents as diffuse anterior knee pain, usually with activities such as squatting, running, stair ascent and descent. It is common in active individuals across the lifespan,1–4 and is a frequent cause for presentation at physiotherapy, general practice, orthopaedic and sports medicine clinics in particular.5 ,6 Its impact is profound, often reducing the ability of those with PFP to perform sporting, physical activity and work-related activities pain-free. Increasing evidence suggests that it is a recalcitrant condition, persisting for many years.7–9 In an attempt to share recent innovations, build on the first three successful biennial retreats and define the ‘state of the art’ for this common, impactful condition; the 4th International Patellofemoral Pain Research Retreat was convened. The 4th International Patellofemoral Research Retreat was held in Manchester, UK, over 3 days (September 2–4th, 2015). After undergoing peer-review for scientific merit and relevance to the retreat, 67 abstracts were accepted for the retreat (50 podium presentations, and 17 short presentations). The podium and short presentations were grouped into five categories; (1) PFP, (2) factors that influence PFP (3) the trunk and lower extremity (4) interventions and (5) systematic analyses. Three keynote speakers were chosen for their scientific contribution in the area of PFP. Professor Andrew Amis spoke on the biomechanics of the patellofemoral joint. Professor David Felson spoke on patellofemoral arthritis,10 and Dr Michael Ratleff's keynote theme was PFP in the adolescent patient.11 As part of the retreat, we held structured, whole-group discussions in order to develop consensus relating to the work presented at the meeting as well as evidence gathered from the literature. ### Consensus development process In our past three International Patellofemoral Research Retreats, we developed a consensus statement addressing different presentation categories.12–14 In Manchester in 2015, we revised the format. For the exercise and …

GAMYB-like genes, flowering, and gibberellin signaling in Arabidopsis.

Abstract: We have identified three Arabidopsis genes with GAMYB-like activity, AtMYB33, AtMYB65, and AtMYB101, which can substitute for barley (Hordeum vulgare) GAMYB in transactivating the barley alpha-amylase promoter. We have investigated the relationships between gibberellins (GAs), these GAMYB-like genes, and petiole elongation and flowering of Arabidopsis. Within 1 to 2 d of transferring plants from short- to long-day photoperiods, growth rate and erectness of petioles increased, and there were morphological changes at the shoot apex associated with the transition to flowering. These responses were accompanied by accumulation of GAs in the petioles (GA(1) by 11-fold and GA(4) by 3-fold), and an increase in expression of AtMYB33 at the shoot apex. Inhibition of GA biosynthesis using paclobutrazol blocked the petiole elongation induced by long days. Causality was suggested by the finding that, with GA treatment, plants flowered in short days, AtMYB33 expression increased at the shoot apex, and the petioles elongated and grew erect. That AtMYB33 may mediate a GA signaling role in flowering was supported by its ability to bind to a specific 8-bp sequence in the promoter of the floral meristem-identity gene, LEAFY, this same sequence being important in the GA response of the LEAFY promoter. One or more of these AtMYB genes may also play a role in the root tip during germination and, later, in stem tissue. These findings extend our earlier studies of GA signaling in the Gramineae to include a dicot species, Arabidopsis, and indicate that GAMYB-like genes may mediate GA signaling in growth and flowering responses.
