BACKGROUND: The concept of free interposition arthroplasty proved successful for small joints of the hand, wrist, and foot, particularly after the use of implants coated with pyrocarbon, which enhanced their tribologic and elastic properties. The present study reports preliminary outcomes of a pyrocarbon-coated interposition shoulder arthroplasty (PISA) implant. METHODS: This was a prospective study of 67 consecutive patients who underwent shoulder PISA at 9 centers...

Subharmonic signals backscattered from gas-filled lipid-shelled microbubbles have generated significant research interest because they can improve the detection and sensitivity of contrast-enhanced ultrasound imaging. However, the emission of subharmonic signals is strongly characterized by a temporal dependence, the origins of which have not been sufficiently elucidated. The features that influence subharmonic emissions need to be identified not only to better develop next-generation microbubble contrast agents, but also to develop more efficient subharmonic imaging (SHI) modes and therapeutic strategies...

"Cross-correction," the transfer of soluble lysosomal enzymes between neighboring cells, forms the foundation for therapeutics of lysosomal storage disorders (LSDs). However, "cross-correction" poses a significant barrier to studying the role of specific cell types in LSD pathogenesis. By expressing the native enzyme in only one cell type, neighboring cell types are invariably corrected. In this study, we present a strategy to limit "cross-correction" of palmitoyl-protein thioesterase-1(PPT1), a lysosomal hydrolase deficient in Infantile Neuronal Ceroid Lipofuscinosis (INCL, Infantile Batten disease) to the lysosomal membrane via the C-terminus of lysosomal associated membrane protein-1 (LAMP1)...

Smith-Magenis syndrome (SMS), a neurodevelopmental disorder characterized by dysmorphic features, intellectual disability (ID), and sleep disturbances, results from a 17p11.2 microdeletion or a mutation in the RAI1 gene. We performed exome sequencing on 6 patients with SMS-like phenotypes but without chromosomal abnormalities or RAI1 variants. We identified pathogenic de novo variants in two cases, a nonsense variant in IQSEC2 and a missense variant in the SAND domain of DEAF1, and candidate de novo missense variants in an additional two cases...

Undergraduate research is often hailed as a solution to increasing the number and quality of science, technology, engineering, and mathematics graduates needed to fill the high-tech jobs of the future. Student benefits of research are well documented but the emerging literature on advisors' perspectives is incomplete: only a few studies have included the graduate students and postdocs who often serve as research advisors, and not much is known about why research advisors choose to work with undergraduate researchers...

AIMS: Quantitatively measure and validate analysis of neural respiratory drive (NRD) using a commercial polysomnography system in children during sleep. METHOD: Surface electromyogram of the diaphragm (sEMGdi) recorded from primary snoring children were analysed. A subset was re-analysed to assess intra- and inter-investigator reproducibility. Effects of different band pass filter settings (20-100Hz vs 10-1000Hz) on sEMGdi amplitude were evaluated. RESULTS: Mean sEMGdi from 45 children aged 4...

In the context of the evolution of care practices, continuing training enables caregivers to keep their practices up-to-date and to treat the patient more as a whole, by drawing on their experience in the field. Trainers support them in the development of academic and practical skills for which the expertise of patients plays a significant and recognised role. Patient-trainers enable caregivers to understand the constraints of chronicity and its treatment, not always visible when a purely clinical approach is adopted...

Healthcare research is developing in France, notably through hospital nursing and paramedical research programmes. Few research projects involve the patients as investigators as part of collaborative studies. These approaches favour the involvement of all the players concerned. Thereby, healthcare research, due to its holistic dimension, encourages the development of collaborative practices between researchers, patients and caregivers.

The deployment of quality approaches in hospitals and the evolution of the place of users in the health care system is resulting in patients becoming more involved in the quality of care. Taking into consideration the contribution of collaborative practices is necessary in order to enable patients and caregivers to work together effectively, and to improve the quality of care. Finally, the recognition of patients' expertise and the implementation of adapted methods allow different points of view to come together and decisions to be made jointly...

Alemtuzumab conditioning is highly effective at reducing the incidence of acute and chronic graft versus host disease (GVHD) in reduced intensity fludarabine and melphalan transplantation with ciclosporin monotherapy. Less frequent and lower dose scheduling may be used with sibling donors but an optimal regimen for matched unrelated donors has not been defined. In this retrospective observational study of 313 patients, the incidence and severity of GVHD was compared in patients receiving three different dose schedules: the standard 100mg regimen (20mg on day -7 to -3), 60mg (30mg day -4 and -2) or 50mg (10mg on day -7 to -3)...

BACKGROUND: The accumulation of advanced glycation endproducts in articular cartilage has been suggested as an etiologic factor in the development and progression of knee osteoarthritis (KOA). METHODS: We conducted a prospective cohort study of skin advanced glycation endproducts (sAGEs) measured non-invasively by skin intrinsic fluorescence and the relationship between sAGE KOA progression in 160 men and 287 women in a sub-cohort of the Osteoarthritis Initiative at a single site...

Given the difficulty in obtaining adequate tissue in NSCLC, we investigated the utility of circulating tumor cells (CTCs) for MET status assessment in NSCLC patients. We used two platforms for CTC capture, and assessed MET expression in CTCs and matched-bronchial biopsies in patients with advanced-stage III/IV lung adenocarcinoma. Baseline peripheral blood was collected from 256 advanced-stage III/IV NSCLC patients from Genentech clinical trials, and from 106 patients with advanced-stage III/IV lung adenocarcinoma treated at the Department of Pneumology, Pasteur Hospital, Nice...

Dietary polyphenols, derived from natural products, have received a great interest for their chemopreventive properties against cancer. In this study, we investigated the effects of phenolic extract of the oleaster leaves (PEOL) on tumor growth in mouse model and on cell death in colon cancer cell lines. We assessed the effect of oleaster leaf infusion on HCT116 (human colon cancer cell line) xenograft growth in athymic nude mice. We observed that oleaster leaf polyphenol-rich infusion limited HCT116 tumor growth in vivo...

BACKGROUND: Since 1984, WHO has endorsed drug treatment to reduce Schistosoma infection and its consequent morbidity. Cross-sectional studies suggest pre-treatment correlation between infection intensity and risk for Schistosoma-related pathology. However, evidence also suggests that post-treatment reduction in intensity may not reverse morbidity because some morbidities occur at all levels of infection, and some reflect permanent tissue damage. The aim of this project was to systematically review evidence on drug-based control of schistosomiasis and to develop a quantitative estimate of the impact of post-treatment reductions in infection intensity on prevalence of infection-associated morbidity...

Chronic alcohol consumption perturbs lipid metabolism as it increases adipose tissue lipolysis and leads to ectopic fat deposition within the liver and the development of alcoholic fatty liver disease. In addition to the recognition of the role of adipose tissue derived fatty acids in liver steatosis, alcohol also impacts other functions of adipose tissue and lipid metabolism. Lipid balance in response to long-term alcohol intake favors adipose tissue loss and fatty acid efflux as lipolysis is upregulated and lipogenesis is either slightly decreased or unchanged...

BACKGROUND: Despite its widespread use, the American Society of Anesthesiologists (ASA)-Physical Status Classification System has been shown to result in inconsistent assignments among anesthesiologists. The ASA-Physical Status Classification System is also used by nonanesthesia-trained clinicians and others. In 2014, the ASA developed and approved examples to assist clinicians in determining the correct ASA-Physical Status Classification System assignment. The effect of these examples by anesthesia-trained and nonanesthesia-trained clinicians on appropriate ASA-Physical Status Classification System assignment in hypothetical cases was examined...
