Nutritional intervention is an essential part of cancer treatments. Research and clinical evidence in cancer have shown that nutritional support can reduce length of hospitalisation, diminish treatment-related toxicity, and improve nutrient intake, quality of life, and physical function. GSK458 Nutritional intervention can improve outcomes and help patients in the successful completion of oncological treatments by preventing malnutrition. Malnutrition is a very common hallmark in patients with cancers. Almost one-fourth of cancer patients are at risk of dying because of the consequences of malnutrition, rather than cancer itself. Patients with digestive cancers are at higher risk of suffering malnutrition due to the gastrointestinal impairment caused by their disease. They are at high nutritional risk by definition, yet the majority of them have insufficient or null access to nutritional intervention.Inadequate resources are dedicated to implementing nutritional services in Europe. Universal access to nutritional support for digestive cancer patients is not a reality in many European countries. To change this situation, health systems should invest in qualified staff to reinforce or create nutritional teams' experts in digestive cancer treatments. We aim to share the patient community's perspective on the status and the importance of nutritional intervention. This is an advocacy manuscript presenting data on the topic and analysing the current situations and the challenges for nutrition in digestive cancers. It highlights the importance of integrative nutrition in the treatment of digestive cancers and advocates for equitable and universal access to nutritional intervention for all patients.The genetics of allorecognition has been studied extensively in inbred lines of Hydractinia symbiolongicarpus, in which genetic control is attributed mainly to the highly polymorphic loci allorecognition 1 (Alr1) and allorecognition 2 (Alr2), located within the Allorecognition Complex (ARC). While allelic variation at Alr1 and Alr2 can predict the phenotypes in inbred lines, these two loci do not entirely predict the allorecognition phenotypes in wild-type colonies and their progeny, suggesting the presence of additional uncharacterized genes that are involved in the regulation of allorecognition in this species. Comparative genomics analyses were used to identify coding sequence differences from assembled chromosomal intervals of the ARC and from genomic scaffold sequences between two incompatible H. symbiolongicarpus siblings from a backcross population. New immunoglobulin superfamily (Igsf) genes are reported for the ARC, where five of these genes are closely related to the Alr1 and Alr2 genes, suggesting the presence of multiple Alr-like genes within this complex. Complementary DNA sequence evidence revealed that the allelic polymorphism of eight Igsf genes is associated with allorecognition phenotypes in a backcross population of H. symbiolongicarpus, yet that association was not found between parental colonies and their offspring. Alternative splicing was found as a mechanism that contributes to the variability of these genes by changing putative activating receptors to inhibitory receptors or generating secreted isoforms of allorecognition proteins. Our findings demonstrate that allorecognition in H. symbiolongicarpus is a multigenic phenomenon controlled by genetic variation in at least eight genes in the ARC complex.
This study investigated the incidence of AVN in patients with cerebral palsy who underwent a hip reconstruction surgery (soft tissue release, femur and pelvic osteotomies) and its impact on quality of life.
Retrospective study, with clinical and radiographic analysis of 104 patients (128 hips) GMFCS IV and V with a minimum twoyear follow-up. Reimers migration percentage, the amount of abduction, acetabular index, and the neck-shaft angle were collected before and after surgery. Modified Tönnis classification was used to analyze the hips before surgery, and the Bucholz and Ogden classification was used to identify hips with AVN. Function and quality of life were investigated with the CPCHILD questionnaire after surgery.
The mean age of participants at surgery was 120.1months (72-184), and it was not related with AVN (p = 0.946). AVN signs were observed in 62 hips (48.5%). The mean pre-op Reimers value was 68.7% (16-100) in normal hips and 83.1% (0-100) in hips with AVN (p = 0.003). All hips considered as Tönnis IV before surgery developed AVN (p = 0.006). The amount of abduction did not differ between hips that developed AVN and those that did not (p = 0.313). Patients who developed AVN had lower scores of quality of life (p = 0.023) and comfort (p = 0.025) according to the CPCHILD questionnaire.
We observed a relationship between the greater pre-operative severity according to the Reimers index and the modified Tonnis classification and the development of AVN.

The purpose of this study was to investigate the incidence, characteristics, and risk factors for venous thromboembolism (VTE) in patients who underwent shoulder arthroplasty (SA) through systematic review.
A search of studies was conducted using the databases for PubMed, EMBASE, Scopus, Ovid, MEDLINE, and Cochrane Library according to the guidelines for PRISMA (Preferred Reporting Items for Systematic Meta-Analyses). Quality assessment was performed using the Methodological Index for Nonrandomized Studies (MINORS).
Nine studies (12,566 shoulders) were finally eligible and the mean MINORS score was 13.2 (ranges, 9-18). The overall incidence of VTE was 0.81% (78/9681) including 0.54% (52/9681) for deep vein thrombosis (DVT) and 0.33% (42/12,566) for pulmonary embolism (PE). There were no significant differences in the incidences according to the type of arthroplasty. DVT was detected at an average of 18.8days after index surgery, and PE was detected at an average of 12.7days after index surgery. The risk treatment, and prophylaxis.Carbon fiber/poly-ether-ether-ketone implants are increasingly being used in orthopedic oncology. An understanding of how to evaluate the normal appearance of these implants is critical for detecting any failures or complications that may arise. The purpose of this manuscript is to provide primarily a radiographic review of the normal radiographic appearance of carbon fiber-reinforced poly-ether-ether-ketone implants in the appendicular skeleton with some cross-sectional imaging discussion. We additionally aim to highlight some of the unique clinical benefits compared to metal implants, review the unique appearance of failures of these implants, and propose a standardized radiologic method for their evaluation. Our review is based on a retrospective case review of 31 patients with carbon fiber-reinforced poly-ether-ether-ketone implants placed in a single center orthopedic oncology practice from 2017 to 2021.Vertebral compression fractures (VCFs) are a common pathologic process seen in 30-50% of individuals over the age of 50 years. Historically, VCFs were first treated with nonsurgical management while vertebral augmentation was reserved for severe cases resulting in deformity or significant disability. Current treatment algorithms based on established appropriateness criteria have changed recommendations towards supporting early vertebral augmentation for the VCFs causing the most clinically difficulty and taking into account the degree of vertebral body height loss, kyphotic deformity, and the degree of clinical progression. Percutaneous vertebroplasty (PVP) involves injecting primarily polymethacrylate (PMMA) bone cement directly into the cancellous bone of the vertebral body. There is recent literature showing the effectiveness of PVP including data comparing vertebroplasty to sham treatment. Vertebroplasty evolved into balloon kyphoplasty (BKP) where a balloon is first inserted into the vertebral body to create a cavity and reduce the fracture followed by an injection of bone cement. Both PVP and BKP have been shown to be significantly more effective at treatment of VCFs compared to nonsurgical management. The benefits shown in the literature have been demonstrated randomized control trials, cohort matched trials, post-market trials, registries, and many other data sources with approximately 250 manuscripts produced per year dedicated to the topic of vertebral augmentation.Members of candidate Asgardarchaeota superphylum appear to share numerous eukaryotic-like attributes thus being broadly explored for their relevance to eukaryogenesis. On the contrast, the ecological roles of Asgard archaea remains understudied. Asgard archaea have been frequently associated to low-oxygen aquatic sedimentary environments worldwide spanning a broad but not extreme salinity range. To date, the available information on diversity and potential biogeochemical roles of Asgardarchaeota mostly sourced from marine habitats and to a much lesser extend from true saline environments (i.e., > 3% w/v total salinity). Here, we provide an overview on diversity and ecological implications of Asgard archaea distributed across saline environments and briefly explore their metagenome-resolved potential for osmoadaptation. Loki-, Thor- and Heimdallarchaeota are the dominant Asgard clades in saline habitats where they might employ anaerobic/microaerophilic organic matter degradation and autotrophic carbon fixation. Homologs of primary solute uptake ABC transporters seemingly prevail in Thorarchaeota, whereas those putatively involved in trehalose and ectoine biosynthesis were mostly inferred in Lokiarchaeota. We speculate that Asgardarchaeota might adopt compatible solute-accumulating ('salt-out') strategy as response to salt stress. Our current understanding on the distribution, ecology and salt-adaptive strategies of Asgardarchaeota in saline environments are, however, limited by insufficient sampling and incompleteness of the available metagenome-assembled genomes. Extensive sampling combined with 'omics'- and cultivation-based approaches seem, therefore, crucial to gain deeper knowledge on this particularly intriguing archaeal lineage.Biomolecular condensates compartmentalize and regulate assemblies of biomolecules engaged in vital physiological processes in cells. Specific proteins and nucleic acids engaged in shared functions occur in any one kind of condensate, suggesting that these compartments have distinct chemical specificities. Indeed, some small-molecule drugs concentrate in specific condensates due to chemical properties engendered by particular amino acids in the proteins in those condensates. Here we argue that the chemical properties that govern molecular interactions between a small molecule and biomolecules within a condensate can be ascertained for both the small molecule and the biomolecules. We propose that learning this 'chemical grammar', the rules describing the chemical features of small molecules that engender attraction or repulsion by the physicochemical environment of a specific condensate, should enable design of drugs with improved efficacy and reduced toxicity.
