Multiple myeloma is a malignancy caused by the clonal expansion of abnormal plasma cells. Myeloma cells have proven to be incredibly successful at manipulating their microenvironment to promote growth and to evade modern therapies. They have evolved to utilise the integral signalling pathways of the bone and bone marrow to drive disease progression. The bone marrow is often described in the context of a single structure that fills the bone cavity and supports normal haematopoiesis. However, within that structure exists two anatomically different niches, the perivascular niche and the endosteal niche. These contain different cell types functioning to support normal immune and blood cell production as well as healthy bone. These cells secrete numerous signalling molecules that can influence myeloma cell biology and behaviour. The endosteal niche is home to specific bone cell lineages and plays a pivotal role in myeloma cell establishment and survival. This review will concentrate on some of the signalling pathways that are hijacked by myeloma cells to shape a favourable environment, and the different influences myeloma cells are exposed to depending on their spatial location within the bone marrow.This paper introduces a new column in the Journal for the exploration of and reflection on the roles and articulations of theory in the health professions education sciences. This introduction provides initial orientation to concepts such as theory as worldview, theory linked to empiricism and paradigm, and theory and reflexivity. The authors invite scholars to submit papers that explore the role of theory in HPE scholarship, that propose new and adapted theoretical positions, and that critique the many theories that might be brought to bear to address questions in the field.Recently, due to scarce resources and the need to provide an evidence-base for healthcare professions' education (HPE), HPE research centres internationally have turned to identifying priorities for their research efforts. Engaging a range of stakeholders in research priority setting exercises has been posited as one way to address the issues around reducing researcher bias and increasing social accountability. However, assigning individuals to single a priori stakeholder groups is complex, with previous research overlooking cross-category membership and agreement between individuals across groups. Further, analyses have pitched stakeholder groups against one another in an attempt to understand who prioritises what, and often fails to grasp rationales underlying priorities. A deeper understanding of who prioritises what research areas and why is required to consider applicability of results across contexts and deepen social accountability and transferability. A web-based Q-methodological approach with n=91 paationales for prioritisation were identified impact, organisational culture and deficit of educators/practitioners were most highly cited. Each Viewpoint, held by multiple stakeholders, comprised a unique set of topic-groupings, target study participants, beneficiaries and rationales. The two most prolific Viewpoints represent how different stakeholder groups highlight key complementary perspectives of healthcare professions' education in the workplace (efficacy of teaching/learning practices, application of knowledge/values). By illuminating the detail around each Viewpoint, and presenting an holistic description of the who-what-why in research priority setting, others wishing to undertake such an exercise can more easily identify how stakeholder Viewpoints and their epistemic beliefs can help shape healthcare professions' research agendas more generally.
To evaluate reserve quadriceps function and improve knee activity in patients with severe knee extension contracture following arthroscopic-assisted mini-incision quadricepsplasty as well as post-operative complications.
From 2012 to 2019, 32 patients with severe knee extension contractures (less than 45° range of flexion) were treated with an all-arthroscopic release technique. The clinical results, including range of motion (ROM), quadriceps function (quadriceps index, QI), and knee function, were evaluated, and MRI of the healed tendon after partial quadricepsplasty was performed. The patellar track and length during knee flexion were measured on three normal knees under fluoroscopy. Three formalin-fixed lower limbs were used to mimic severely contracted quadriceps to evaluate the extension of the patellar track.
The median follow-up time was 2.1 years (1-5 years). The average QI was 92.0 ± 6.2, and the quadriceps muscle strength was increased from 3.28 to 4.72. At the final follow-up, 90% of the patients had no difficulty going upstairs, going downstairs, or rising from a chair. The ROM improved by 25.69 ± 3.6 preoperatively to 105.88 ± 6.6 at the final follow-up (P < 0.001). The open surgery showed that a 2-cm extension could be achieved by partly cutting the quadriceps tendon, and two cuts achieved a total extension of 5.2 ± 0.52 cm. The patellar tracking distance was 7.7 ± 0.43 cm, and the gap between the patella and femur was also reduced.
Partial quadricepsplasty of the rectus femoris extended the contracted quadriceps and maintained quadriceps strength, allowing for full knee flexion and satisfactory clinical outcomes of knee function with few complications.

However, little information is available on the microbial populations in the cantaloupe farm environment. The purpose of this work was to characterize the bacterial communities present on cantaloupe farms. Fruit, soil, and harvester hand rinsates were collected from two Mexican cantaloupe farms, each visited three times. Microbiome analysis was performed by sequencing 16sRNA and analyzed using qiime2 software. Correlations were determined between sample type and microbial populations. The α and β diversity analysis identified 2777 sequences across all samples. selleck inhibitor The soil samples had the highest number and diversity of unique species (from 130 to 1329 OTUs); cantaloupe (from 112 to 205 OTUs), and hands (from 67 to 151 OTUs) had similar diversity. Collectively, Proteobacteria was the most abundant phyla (from 42 to 95%), followed by Firmicutes (1-47%), Actinobacteria ( less then 1 to 23%), and Bacteroidetes ( less then 1 to 4.
