he best of both worlds.This study investigated the reliability of sonoelastography techniques in quantifying lower limb tendon elasticity. A literature search was conducted using PubMed, Web of Science and CINAHL. The quality of the selected papers was evaluated using the Guidelines for Reporting Reliability and Agreement Studies and the Quality Appraisal Tool for Studies of Diagnostic Reliability checklist. Reliability values were extracted and synthesized. Twenty-four studies were included and were divided by the two main technologies used strain and shear-wave elastography. The overall methodological quality was questionable; all studies were at risk of bias. Highly variable results ranging from poor to excellent reliability were found for both technologies and for all tendons considered. Intra-rater reliability of strain elastography on the Achilles tendon and shear-wave elastography on the patellar and quadriceps tendon was adequate. Inter-rater, inter-session and inter-machine reliability was insufficient. Caution should be used when interpreting results from sonoelastography studies measuring lower limb tendon elasticity.To evaluate fracture stability and complications such as infections, need for hardware removal, malunion, and nonunion when using 2.0-mm locking plating system in fixation of mandible fractures and to compare these to those associated with the 2.0-mm non-locking plating system. A prospective clinical study was conducted in a cohort of mandible fracture patients who were randomly assigned to two groups. Patients in the non-locking group were treated with 2.0-mm non-locking plating system, and those in locking group were treated with 2.0-mm locking plating system. Fracture stability, need for maxillomandibular fixation (MMF) and postoperative complications were assessed and compared. A total of 60 patients (30 in each group) were recruited. Significant differences were found between the two groups with respect to postoperative fracture stability (P = 0.001) and need for MMF (P = 0.005). Multivariate analysis revealed that type of fixation was not the only dependent variable which affected fracture stability. There were no significant differences in postoperative complications between the two groups. The 2.0-mm locking plating system provides greater stability and early functional restoration than the 2.0-mm non-locking plating system, with similar rates of postoperative complications. Thus, it can be used as a reliable and effective treatment modality for treating mandibular fractures.

Endoscopic submucosal dissection (ESD) is a well-established treatment for superficial gastrointestinal tumors and enables en bloc resection. Adequate tissue tension is important for safe and effective dissection. Simplified magnetic anchor-guided ESD (MAG-ESD) with a neodymium magnet has potential benefits, compared with other current traction methods. We evaluated the feasibility of simplified MAG-ESD in an ex vivo porcine model.

An experimental study was conducted, utilizing the standard ESD technique. An external magnet and an internal magnet, both neodymium magnets, were used for the magnetic anchoring. The internal magnet was attached to an arm of a hemoclip with a 2-0 silk suture. BMS935177 After the incision, the clip with the internal magnet was placed at the edge of the lesion. The external magnet was maneuvered around the surface to apply adequate tension.

A total of 15 en bloc ESDs (five with no magnetic anchoring and 10 with magnetic anchoring) were carried out. Traction and dissection were feasible in all cases and the procedures were completed in fewer than 90 min. Lesion size ranged from 15 to 50 mm (mean 30 mm). Two cases in the group with magnetic anchoring presented with punctate perforation (13.3%).

Our study demonstrated the feasibility of simplified MAG-ESD and en bloc resection in an ex vivo porcine model.

This study aims at investigating the epidemiological profile of chronic hepatitis C (CHC) regarding hepatitis C virus (HCV) genotype in Taiwan.

A total of 29,087 CHC patients with advanced fibrosis who received direct-acting antivirals (DAAs) therapy under Taiwan's National Health Insurance (NHI) during 2017-2018 were recruited. The HCV genotype distribution and its association with patients' demographic factors including age, gender, and geographical areas were examined.

The most common genotypes were 1b (59.5%) and 2 (30.1%) with characteristics of older age (mean±standard deviation (SD) 66.5±10.7 years and 67.3±10.9 years) and female gender predominant (57.1% and 59.4%), which were associated with iatrogenic infection decades ago. Most of patients with genotype 1a (5.9%) and 6 (3.7%) infection were relatively younger (59.2±12.0 years and 60.0±13.8 years) and male gender predominant (59.1% and 61.1%), except Liujia and Liuying districts in southern Taiwan. The youngest group (53.2±11.8 years) and most male gender predominant (74.3%) was genotype 3 (0.37%). These genotypes with characteristics of being younger and male gender predominant were highly related to injection drug use in recent years. The number of genotype 4 patients were extremely rare (n=25) and efficacy of genotype-4-specific-DAA was significantly poorer than non-genotype-4-specific DAA (P value=0.0411).

The significant differences in demographic characteristics among CHC patients with different HCV genotypes found in this study suggest HCV genotype was highly associated with transmission pattern and may be used as a reference for HCV control.

To summarize the current available evidence on the use of behavior change theories to explain and change physical activity behavior in urological cancer survivors.

Five electronic databases including Medline, Web of Science, Embase, Cochrane, and Psych INFO and reference lists of key studies were searched between database inception and November 2020. Peer-reviewed articles on the use of behavior change theories to understand or change physical activity in urological cancer survivors were included.

The theory of planned behavior and the social cognitive theory were the most used theories to explain and change physical activity behavior in urological cancers, respectively. However, the use of behavior change theories in physical activity interventions for urological cancers is still low across all urological tumor groups. Planning frameworks such as the intervention mapping approach should be used to enhance the systematic use of behavior change theories during every phase of intervention development. In addition, more research is needed to identity which behavior change techniques are most effective to change physical activity behavior in urological cancer survivors.

Nurses play a key role in the urological cancer patients' clinical pathway and should be able to motivate patients to engage in sufficient physical activity levels. Therefore, it is important that nurses understand the underlying reasons why patients (do not) engage in physical activity and which behavior change techniques are most effective in changing a patients' behavior.

With norovirus vaccine candidates currently under development, now is the time to identify the vaccine characteristics and implementation thresholds at which vaccination becomes cost effective and cost saving in a community setting.

In 2020, a norovirus transmission, clinical, and economics computational simulation model representing different U.S. population segments was developed to simulate the spread of norovirus and the potential impact of vaccinating children aged <5 years and older adults (aged ≥65 years).

Compared with no vaccination, vaccinating preschool-aged children averted 8%-72% of symptomatic norovirus cases in a community, whereas vaccinating older adults averted 2%-29% of symptomatic cases (varying with vaccine efficacy [25%-75%] and vaccination coverage [10%-80%]). Vaccination with a 25% vaccine efficacy was cost effective (incremental cost-effectiveness ratio ≤$50,000 per quality-adjusted life year) when vaccination cost ≤$445 and cost saving at ≤$370 when vaccinating preschool-agelds can help provide decision makers with targets to consider when developing and implementing a norovirus vaccine.Common variable immunodeficiency disorders (CVID) are the most common symptomatic primary antibody deficiency in adults with an estimated prevalence of 1/25,000. The most frequent clinical manifestations are upper respiratory tract infections (including pneumonia, bronchitis, and sinusitis) predominantly with Streptococcus pneumoniae or H. influenzae. However, CVID are complicated in 20 to 30 % of cases of non-infectious manifestations which have been well characterized in recent years. Several complications can be observed including autoimmune, lymphoproliferative, granulomatous or cancerous manifestations involving one or more organs. These complications, mostly antibody-mediated cytopenias, are correlated with a decrease in the number of circulating switched memory B cells. Replacement therapy with polyvalent gammaglobulins has greatly improved the prognosis of these patients but it remains poor in the presence of digestive complications (especially in the case of chronic enteropathy and/or porto-sinusoidal vascular disease), pulmonary complications (bronchiectasis and/or granulomatous lymphocytic interstitial lung disease) and when progression to lymphoma. Much progress is still to be made, in particular on the therapeutic management of non-infectious complications which should benefit in the future from targeted treatments based on knowledge of genetics and immunology.

We sought to investigate the tumor control probability (TCP) of spinal metastases treated with stereotactic body radiation therapy (SBRT) in 1 to 5 fractions.

PubMed-indexed articles from 1995 to 2018 were eligible for data extraction if they contained SBRT dosimetric details correlated with actuarial 2-year local tumor control rates. Logistic dose-response models of collected data were compared in terms of physical dose and 3-fraction equivalent dose.

Data were extracted from 24 articles with 2619 spinal metastases. Physical dose TCP modeling of 2-year local tumor control from the single-fraction data were compared with data from 2 to 5 fractions, resulting in an estimated α/β = 6 Gy, and this was used to pool data. Acknowledging the uncertainty intrinsic to the data extraction and modeling process, the 90% TCP corresponded to 20 Gy in 1 fraction, 28 Gy in 2 fractions, 33 Gy in 3 fractions, and (with extrapolation) 40 Gy in 5 fractions. The estimated TCP for common fractionation schemes was 82% at 18 Gy, 90% for 20 Gy, and 96% for 24 Gy in a single fraction, 82% for 24 Gy in 2 fractions, and 78% for 27 Gy in 3 fractions.
