Removal involving rare adult cervical thymic cyst.
The results provide evidence of good-excellent reproducibility of the 6MWT with children and youth with JIA and support the use of the 6MWT as a measure of exercise capacity in clinical practice and research.Surgical sutures are indispensable for a vast majority of operative procedures. An ideal suture is characterized by high tissue compliance without cutting into the mended tissue and optimal biocompatibility. Therefore, we assessed these mechanical and biological properties for novel elastic thermoplastic polyurethane (TPU) and cross-sectional modified "snowflake" sutures. Circular and "snowflake"-shaped TPU threads were manufactured and compared to similar surface modified polyvinylidene fluoride (PVDF) sutures. Regular PVDF sutures were used as the control group. Single-axis tensile test with and without gelatinous tissue surrogates were performed to evaluate the suture incision into the specimens. Biocompatibility was evaluated by subcutaneous implantation (n = 18) in rats for 7 and 21 days. Histology and immunohistology was conducted for assessment of the foreign body reaction. Regular and modified TPU threads showed a significant reduction of incision into the tissue surrogates compared to the control. Both TPU sutures and the modified PVDF sutures achieved comparable biocompatibility versus regular PVDF threads. Detailed histology revealed novel tissue integration into the notches of the surface modified sutures, we termed this newly shaped granuloma "intrafilamentous" granuloma. Elastic TPU threads showed a significant reduction of tissue surrogate incision and suture tension loss. Biocompatibility did not significantly differ from standard PVDF. Histology demonstrated tissue ingrowth following the surface modification of the suture referred to as "intrafilamentous" granuloma.

Neurodegeneration is a complex cellular process linked to prompt changes in myelin integrity and gradual neuron loss. Current imaging techniques offer estimations of myelin volumes in lesions/remyelinated areas but are limited to detect subtle injury.

To investigate whether measurements detected by a signal hierarchically isolated as a function of time-to-echo (SHIFT) MRI technique can determine changes in myelin integrity and fiber axolemma.

Prospective animal model.

Surgically demyelinated spinal cord (SC) injury model in rodents (n = 6).

Gradient-echo spin-echo at 3T.

Multicompartment T
relaxations were computed by SHIFT MRI in 75-microns-resolution images of the SC injury penumbra region 2 weeks post-trauma. G-ratio and axolemma delamination were assessed by transmission electron microscopy (TEM) in intact and injured samples. SC myelinated nerve fraction was computed by SHIFT MRI prospectively and assessed histologically.

Relations between SHIFT-isolated T
-components and TEM measuremenith abnormal intermembrane spaces formed upon mild injury, directly correlated with early neuro integrity loss. Level of Evidence 1 Technical Efficacy Stage 2.

To investigate current awareness and practices of neurological prognostication in comatose cardiac arrest (CA) patients.

An anonymous questionnaire was distributed to 1600 emergency physicians in 75 hospitals which were selected randomly from China between January and July 2018.

92.1% respondents fulfilled the survey. The predictive value of brain stem reflex, motor response and myoclonus was confirmed by 63.5%, 44.6% and 31.7% respondents, respectively. Only 30.7% knew that GWR value<1.1 indicated poor prognosis and only 8.1% know the most commonly used SSEP N20. Status epilepticus, burst suppression and suppression were considered to predict poor outcome by only 35.0%, 27.4% and 20.9% respondents, respectively. Only 46.7% knew NSE and only 24.7% knew S-100. Only a few respondents knew that neurological prognostication should be performed later than 72hours from CA either in TTM or non-TTM patients. In practice, the most commonly used method was clinical examination (85.4%). Only 67.9% had used brain CT for prognosis and 18.4% for MRI. NSE (39.6%) was a little more widely used than S-100β (18.0%). However, SSEP (4.4%) and EEG (11.4%) were occasionally performed.

Neurological prognostication in CA survivors had not been well understood and performed by emergency physicians in China. They were more likely to use clinical examination rather than objective tools, especially SSEP and EEG, which also illustrated that multimodal approach was not well performed in practice.

This study investigated the change in self-rated health (SRH) status among elderly Koreans and sought influential factors affecting SRH by reference to data collected during the Korean Community Health Survey 2008-2017.

We obtained raw data from the Korea Community Health Survey for 10 years (2008-2017), which included sociodemographic and health information on Koreans aged ≥65 years (242 552 men and 349 586 women). SRH was measured using the SRH scale and divided into not-poor and poor. Logistic regression analyses of poor SRH were performed using a weighted sampling method and interaction models (year × variables) to represent the entire Korean elderly population and estimate the changes in poor SRH over time.

The proportion of elderly subjects in the population increased over 10 years. After adjusting for all confounding variables, the weighted adjusted odds ratios for poor SRH decreased consistently between 2008 and 2017 (men 0.64, 95% confidence interval 0.50-0.81; women 0.62, 0.46-0.83). The odds ratios for poor SRH were markedly higher in subjects who reported being stressed (men 7.
