Sequencing Gut Microbiota to Visualize Population Changes with Age

This is an interesting study; you'll have to actually look at the open access paper to see the meat of it, which is the various graphs showing the changes in relative population size of different microbe families in the gut that take place with age. A great deal of work on the gut microbiome and its role in health and aging is presently taking place in the scientific community; researchers have identified a number of beneficial metabolites that are produced by classes of microbe that decline with age. Further, the gut microbiome becomes ever more inflammatory with age. The size of these effects on health might be in the same ballpark as those of regular exercise, but the reasons why changes take place are not yet fully understood. The causative mechanisms seem fairly clear in and of themselves, meaning declining immune function, changes in diet, and so forth, but how they interact and which are primary and which are secondary is yet to be firmly resolved. We obtained RNA sequencing data of subjects ranging from newborns to centenarians from a previous study, and summarized the data into a relative abundance matrix of genera in all the samples. Without using the age information of samples, we applied an unsupervised algorithm to recapitulate the underlying aging progression of microbial community from hosts in different age groups and identify genera associated to this progression. Literature review of these identified genera indicated that for individuals with advanc...

There is an urgent need to share expertise and offer emergency guidance for breast radiation therapy (RT) during the COVID-19 (Coronavirus) pandemic. As per the World Health Organisation (WHO) statement, our aim and obligation should be “to stop, contain, control, delay and reduce the impact of this virus at every opportunity”. In our roles as healthcare professionals and/or breast cancer experts this translates to minimising exposure of our patients to COVID-19 without compromising oncological outcome.

Purpose: The availability of novel imaging modalities (NIM) in prostate cancer (PCa) has overtaken the evidence informing their use. The recent EORTC consensus statement on modern imaging recognises the need for large-scale clinical trials of novel imaging [1]. The UK environment is well placed to conduct such trials; the NCRI prostate cancer CSG wished to benchmark current UK imaging availability and practice to inform future national trials.

Purpose: The role of pelvic nodal irradiation in prostate cancer remains controversial. Nevertheless, many high-risk patients are treated with prostate and pelvis radiotherapy in addition to androgen deprivation therapy (ADT) [1]. A recent retrospective study [2] and data from the UK Stampede control arm [3] suggest that radiotherapy may be of benefit to node positive patients. The aim of our study was to document outcomes in patients with node positive prostate cancer treated with pelvic nodal radiotherapy in a UK cancer centre.

Purpose: Relapsed or progressive prostate cancer frequently manifests as consecutive PSA rises long before disease is clinically detectable. Imaging with novel radiotracers targeting prostate-specific membrane antigen (PSMA) has been shown to be more sensitive in identifying the site of disease at lower PSA levels compared with conventional imaging, which may provide increased opportunity for salvage therapy, more aggressive local management of oligometastatic disease or increased confidence in proceeding with systemic therapy [1].

Purpose: To assess the benefits and risks of co-administering maintenance prednisolone with docetaxel and androgen-deprivation therapy (ADT) in hormone sensitive metastatic prostate cancer (HSMPC).

Purpose: As doctors we are required to take consent for radiotherapy; we typically take written consent [1]. We must tell a patient if a treatment might result in a serious adverse outcome, even if the likelihood is very small [2]. As many cancer centres move towards tumour site-specific consent forms for prostate radiotherapy we wanted to ascertain if there was consensus.

Purpose: Synchronous chemotherapy with mitomycin C and 5-FU with radiotherapy may have an additional benefit over radiotherapy alone [1]. We looked into the rate of recurrence and median overall survival between these two groups of patients.

Purpose: The use of FDG PET has become more readily available over the past 15 years. It can be used to aid initial staging of testicular tumours and also assess the response to treatment in the metastatic setting, especially as residual masses are frequently seen after chemotherapy. There have been some recent concerns that FDG PET used to assess for residual disease may have a low positive predictive value [1]. A retrospective audit was carried out to look at the performance of FDG PET in seminoma patients treated at the Edinburgh Cancer Centre.

Purpose: The STAMPEDE trial has recently shown a benefit in overall survival by irradiating the prostate of patients with newly diagnosed metastatic prostate cancer [1]. This benefit was only shown in patients with low burden of metastatic disease, as per the CHAARTED criteria [2]. The current standard of care for these patients is androgen deprivation therapy ± docetaxel chemotherapy and radiotherapy to symptomatic areas of disease if required. The aim of this audit is to determine the potential number of men with low burden of metastatic disease who may require additional radiotherapy.
