750-0.875), mTCI-LHL (0.640-1.060), and mTCI-MHL (0.740-0.900), beyond which the likelihood of elbow stiffness significantly increased (P less then .001). By multivariate analysis, mTCI-HA (odds ratio [OR] 26.22, 95% confidence interval [CI] 3.39-203.07, P = .002), mTCI-LHL (OR 5.37, 95% CI 2.17-13.28, P less then .001), and mTCI-MHL (OR 5.95, 95% CI 1.91-18.56, P = .002) values beyond the optimal ranges were identified as the independent risk factors for elbow stiffness. The interrater reliability of mTCI-HA, mTCI-LHL, and mTCI-MHL was 0.986, 0.983, and 0.987, respectively. Conclusion The mTCI measurement method is reliable. Either too small or too large mTCI values were associated with post-traumatic elbow stiffness among adult patients with type C2-3 distal humeral fractures. The mTCI-HA showed a better predictive value than mTCI-LHL and mTCI-MHL.The human gut microbiota is the most important active part of the intestinal micro-ecosystem. Lifestyle modification, drug intake and nutrition have an impact on the composition of the gut microbiota and its metabolites. This review focuses on the effects of changes in the gut microbiota as well as the important metabolite Trimethylamine-N-oxide (TMAO). Furthermore, relevant therapeutic options to target the human microbiome in patients with cardiovascular disease are presented.The capability to produce customizable 3D printed imaging phantoms out of a growing number of materials has contributed to the increased use of such phantoms in clinical practice and research. Many of these materials have not been characterized at clinically relevant parameters for nuclear medicine imaging. In this work, we measured the attenuation of several 3D printing metal-infused filament materials with the potential for blocking 122 keV gamma photons using a scintillation detector. Understanding the ability of each material to attenuate gamma rays would allow modelling of varying levels of attenuation required for different body tissues at this energy. In addition, it allows for the determination of the thickness of the material needed to attenuate 122 keV photons, in order to build high-contrast spatial resolution phantoms. To achieve this goal, we performed attenuation experiments for three different 3D printing materials in this work (Tungsten infused Acrylonitrile Butadiene Styrene (ABS), Iron infused Polylactic Acid (PLA), and Stainless Steel (SS) infused PLA), by observing gamma transmission through blocks made of each material as a function of thickness. A Cobalt-57 (Co-57; 122 keV) source was chosen because of its relevance to nuclear medicine. Tungsten infused ABS showed the highest measured attenuation coefficient out of the three candidates at this energy (1.452 cm2/g). We further designed and 3D printed an imaging phantom to aid in characterizing the spatial resolution of novel gamma imaging systems at the above energy. The phantom design contains multiple line pairs (lp) located in four quadrants ranging from 1.2 mm - 8 mm. The 3D printed phantom was imaged by a molecular breast tomosynthesis (MBT) gamma camera. Assessment of the intrinsic spatial resolution of the MBT camera showed that our 3D printed phantom might be a viable option for routine spatial resolution quality control (QC) of gamma cameras used in clinical practice.Robotic assistive devices are able to enhance physical stability and balance. Smart walkers, in particular, are also capable of offering cognitive support for individuals whom conventional walkers are unsuitable. However, visually impaired individuals often need additional sensorial assistance from those devices. This work proposes a smart walker with an admittance controller for guiding visually impaired individuals along a desired path. The controller uses as inputs the physical interaction between the user and the walker to provide haptic feedback hinting the path to be followed. Such controller is validated in a set of experiments with healthy individuals. At first, users were blindfolded during navigation to assess the capacity of the smart walker in providing guidance without visual input. Then, the blindfold is removed and the focus is on evaluating the human-robot interaction when the user had visual information during navigation. The results indicate that the admittance controller design and the design of the guidance path were factors impacting on the level of comfort reported by users. In addition, when the user was blindfolded, the linear velocity assumed lower values than when did not wear it, from a mean value of 0.19 m/s to 0.21 m/s.Background/purpose Rosacea has been linked to inflammatory bowel disease and small bowel bacterial overgrowth. We aimed to investigate the fecal microbial profiling and the potential gene functions between rosacea and non-rosacea subjects. Methods A case-control study. Fecal microbiome and predicted genetic function inferred from high-throughput 16S ribosomal RNA sequencing were analyzed between rosacea (n = 11) and age-, gender- and body mass index-matched non-rosacea subjects (n=110). The correlation between altered microbiome as well as lifestyle and diet were also investigated. Results A significant reduction of fecal microbial richness was found in rosacea patients. A distinct fecal microbial community structure was demonstrated in rosacea patients. selleck products The discriminating enriched genera in rosacea patients included Rhabdochlamydia, CF231, Bifidobacterium, Sarcina, Ruminococcus, belonging to the phylum of Chlamydiae, Bacteroidetes, Actinobacteria, and Lentisphaerae. The discriminating reduced abundant genera included Lactobacillus, Megasphaerae, Acidaminococcus, Hemophilus, Roseburia, Clostridium, belong to the phylum of Firmicutes; and Citrobacter, belonging to the phylum of Proteobacteria. The distinct fecal microbial composition might be related to sulfur metabolism, cobalamin, and carbohydrate transport. Conclusion An altered fecal microbial richness and composition were observed in rosacea patients. The distinct microbial composition might be related to sulfur metabolism, cobalamin and carbohydrate transport.Background Scalp angiosarcomas (AS) are aggressive soft tissue sarcomas that present with outcomes different from other AS of the head and neck region. Due to the rarity of the disease, limited data on the clinical outcome of scalp AS are available. In particular, the prognostic significance of surgical margins remains controversial and the impact of margin status on survival has not been documented. Methods We retrospectively reviewed 41 scalp AS patients, including 30 patients with localized disease and 11 patients with initial distant metastasis, treated in our institution between 1997 and 2017. Survival was determined by Kaplan-Meier analysis. In the 30 patients without distant metastasis (localized disease), univariate and multivariate analysis using the Cox proportional hazards model were used to determine clinicopathologic characteristics associated with recurrence free survival (RFS), locoregional control (LRC), and overall survival (OS). Results Totally 41 patients diagnosed with scalp AS were identified, including 30 patients with localized disease and 11 patients with initial distant metastasis on diagnosis.
