Treatment of pain following cancer : applying neuro-immunology in rehabilitation practice

Aim: Pain is the second most frequent persistent symptom following cancer treatment. This article aims at explaining how the implementation of contemporary pain neuroscience can benefit rehabilitation for adults following cancer treatment within an evidence-based perspective. Materials and methods: Narrative review. Results: First, pain education is an effective but underused strategy for treating cancer related pain. Second, our neuro-immunological understanding of how stress can influence pain highlights the importance of integrating stress management into the rehabilitation approach for patients having cancer-related pain. The latter is supported by studies that have examined the effectiveness of various stress management programmes in this population. Third, poor sleep is common and linked to pain in patients following cancer treatment. Sleep deprivation results in a low-grade inflammatory response and consequent increased sensitivity to pain. Cognitive behavioural therapy for sleep difficulties, stress management and exercise therapy improves sleep in patients following cancer treatment. Finally, exercise therapy is effective for decreasing pain in patients following cancer treatment, and may even decrease pain-related side effects of hormone treatments commonly used in cancer survivors. Conclusions: Neuro-immunology has increased our understanding of pain and can benefit conservative pain treatment for adults following cancer treatment

A century of temporal stability of genetic diversity in wild bumblebees

Since the 1950s, bumblebee (Bombus) species are showing a clear decline worldwide. Although many plausible drivers have been hypothesized, the cause(s) of this phenomenon remain debated. Here, genetic diversity in recent versus historical populations of bumblebee species was investigated by selecting four currently restricted and four currently widespread species. Specimens from five locations in Belgium were genotyped at 16 microsatellite loci, comparing historical specimens (1913-1915) with recent ones (2013-2015). Surprisingly, our results showed temporal stability of genetic diversity in the restricted species. Furthermore, both historical and recent populations of restricted species showed a significantly lower genetic diversity than found in populations of co-occurring widespread species. The difference in genetic diversity between species was thus already present before the alleged recent drivers of bumblebee decline could have acted (from the 1950's). These results suggest that the alleged drivers are not directly linked with the genetic variation of currently declining bumblebee populations. A future sampling in the entire distribution range of these species will infer if the observed link between low genetic diversity and population distribution on the Belgium scale correlates with species decline on a global scale

Feasibility and safety of PIPAC combined with additional surgical procedures: PLUS study.

PIPAC (Pressurized IntraPeritoneal Aerosol Chemotherapy) is a minimally invasive approach relying on physical principles for improving intraperitoneal drug delivery, including optimizing the homogeneity of drug distribution through an aerosol. Feasibility and safety of the new approach are now consolidated and data on its effectiveness are continuously increasing. Although any surgical procedure associated with PIPAC had always been discouraged due to the high risk of complications, surgical practice is constantly changing: with growing expertise, more and more surgical teams associate PIPAC with surgery. PLUS study is part of the retrospective international cohort studies including 10 centers around the world (India, Italy, France, Germany, Belgium, Russia, Saudi Arabia, Switzerland) and 96 cases of combined approaches evaluated through a propensity score analysis. the procedures most frequently associated with PIPAC were not only adhesiolysis, omentectomy, adnexectomy, umbilical/inguinal hernia repairs, but also more demanding procedures such as intestinal resections, gastrectomy, splenectomy, bowel repair/stoma creation. Although the evidence is currently limited, PLUS study demonstrated that PIPAC associated with additional surgical procedures is linked to an increase of surgical time (p < 0.001), length of stay (p < 0.001) and medical complication rate (p < 0.001); the most frequently reported medical complications were mild or moderate in severity, such as abdominal pain, nausea, ileus and hyperthermia. No difference in terms of surgical complications was registered; neither reoperation or postoperative deaths were reported. these results suggest that PIPAC can be safely combined in expert centers with additional surgeries. Widespread change of practice should be discouraged before the results of ongoing prospective studies are available

Recommendations for interoperability among infrastructures

The BiCIKL project is born from a vision that biodiversity data are most useful if they are presented as a network of data that can be integrated and viewed from different starting points. BiCIKL’s goal is to realise that vision by linking biodiversity data infrastructures, particularly for literature, molecular sequences, specimens, nomenclature and analytics. To make those links we need to better understand the existing infrastructures, their limitations, the nature of the data they hold, the services they provide and particularly how they can interoperate. In light of those aims, in the autumn of 2021, 74 people from the biodiversity data community engaged in a total of twelve hackathon topics with the aim to assess the current state of interoperability between infrastructures holding biodiversity data. These topics examined interoperability from several angles. Some were research subjects that required interoperability to get results, some examined modalities of access and the use and implementation of standards, while others tested technologies and workflows to improve linkage of different data types.These topics and the issues in regard to interoperability uncovered by the hackathon participants inspired the formulation of the following recommendations for infrastructures related to (1) the use of data brokers, (2) building communities and trust, (3) cloud computing as a collaborative tool, (4) standards and (5) multiple modalities of access:If direct linking cannot be supported between infrastructures, explore using data brokers to store linksCooperate with open linkage brokers to provide a simple way to allow two-way links between infrastructures, without having to co-organize between many different organisationsFacilitate and encourage the external reporting of issues related to their infrastructure and its interoperability.Facilitate and encourage requests for new features related to their infrastructure and its interoperability.Provide development roadmaps openlyProvide a mechanism for anyone to ask for helpDiscuss issues in an open forumProvide cloud-based environments to allow external participants to contribute and test changes to featuresConsider the opportunities that cloud computing brings as a means to enable shared management of the infrastructure.Promote the sharing of knowledge around big data technologies amongst partners, using cloud computing as a training environmentInvest in standards compliance and work with standards organisations to develop new, and extend existing standardsReport on and review standards compliance within an infrastructure with metrics that give credit for work on standard compliance and developmentProvide as many different modalities of access as possibleAvoid requiring personal contacts to download dataProvide a full description of an API and the data it servesFinally, the hackathons were an ideal meeting opportunity to build, diversify and extend the BiCIKL community further, and to ensure the alignment of the community with a common vision on how best to link data from specimens, samples, sequences, taxonomic names and taxonomic literature

Fishmeal replacement in feed for rainbow trout (Oncorhynchus mykiss)

The use of fishmeal and fish oil for aquaculture purposes is often questioned as it is considered to be non-sustainable. The cultivation of carnivorous species in particular requires an input of fishmeal and fish oil - often ex-pressed as FIFO: Fish In / Fish Out ratio - which, in theory, can be greater than 1. Although enormous progress has been made in this area in recent decades by reducing the fishmeal content (and replacing it by e.g. vegetable pro-tein sources) in feeds on the one hand and improved feed conversion (FCR) on the other, the search for high-performance, alternative protein sources remains very relevant. In this regard, insect meal can be an interesting option, as well as so-called single cell proteins (SCP) that are a by-product of various fermentation processes - whether or not modified. The main objective of this research was to investigate the potential of a composite core based on SCP as a fishmeal replacer for rainbow trout (Oncorhynchus mykiss) - a carnivorous species. Large volumes are grown in Europe and there is an increasing demand for more sustainable feeds. In this respect, the replacement of fishmeal by SCP could offer an answer.status: Published onlin
