rence of high SI on MRI, seems to be essential for postoperative functional improvement regardless the above-mentioned confounders.Level of Evidence 3.

Surgery for DCM leads to significant functional improvement. However, better outcome was observed in younger individuals with lower CCI and absence of radiographic myelopathy signs. Therefore, DCM surgery, particularly before occurrence of high SI on MRI, seems to be essential for postoperative functional improvement regardless the above-mentioned confounders.Level of Evidence 3.

Retrospective study.

A retrospective study was conducted to clarify the prognostic factors of postoperative for cervical spine fractures patients with ankylosing spondylitis (AS).

Now the high probability of cervical fractures in patients with AS is unanimously recognized. Fractures mostly occur in the lower cervical spine and two-thirds of patients are accompanied by spinal cord injury. But there are few studies on treatment of AS patients with cervical fracture and it is unclear whether the surgical method, timing of surgery, basic treatment of AS, and different doses of steroids therapy have an impact on the prognosis. Thus, this study aims to evaluate the impact of perioperative factors on the prognosis of traumatic cervical fractures in surgical patients with AS.

Preoperative and postoperative spinal cord function were assessed according to the Japanese Orthopaedic Association (JOA) Scores and Improvement rate were calculated. The neck pain severity were rated using a visual analogue scale (VAS) reoperative steroid application as soon as possible.

Retrospective cohort study.

The purpose of this study was to utilize the National Readmission Database to determine the national estimates of complication and 90-day readmission rates associated with cervical spinal fusion in adult patients with rheumatoid arthritis (RA).

RA patients who undergo cervical spine surgery are known to be at high risk for readmissions, which are costly and may not be reimbursed by Medicare.

The National Readmission Database was queried for adults (>18 years) diagnosed with RA undergoing cervical spine fusion. Patient, operative, and hospital factors were assessed in bivariate analyses. Pemigatinib solubility dmso Independent risk factors for readmissions were identified using stepwise multivariate logistic regression.

From 2013 to 2014, a total of 5597 RA patients (average age 61.5 ± 11.2 years, 70.9% female) underwent cervical spine fusion. A total of 691 (12.3%) patients were readmitted within 90 days (). Index inpatient complications included dysphagia (readmitted 7.9% vs. non-readmitted 5.1%; P = 0.003), urinary tract infection (UTI) (8.8% vs. 3.7%; P < 0.001), respiratory-related complications (7.6% vs. 3.4%; P < 0.001), and implant-related complications (5.4% vs. 2.7%; P < 0.001). Multivariate logistic regression demonstrated the following as the strongest independent predictors for 90-day readmission intraoperative bleeding (odds ratio [OR] 3.6, P = 0.001), inpatient Deep Vein Thrombosis (DVT) (OR 4.1, P = 0.004), and patient discharge against medical advice (OR 33.5, P = 0.001).

Readmission rates for RA patients undergoing cervical spine surgery are high and most often due to postoperative infection (septicemia, UTI, pneumonia, wound). Potential modifiable factors which may improve outcomes include minimizing intraoperative blood loses, postoperative DVT prophylaxis, and discharge disposition.

3.Lung cancer always ranks first in the number of cancer deaths every year, accounting for 18.4% of total cancer deaths in 2018. Metastasis is the main cause of death in lung cancer patients. The identification of bioactive components of traditional Chinese medicine is very important for the development of novel reagents against non-small cell lung cancer (NSCLC). Rosthorin A has originated from Rabdosia rosthornii (Diels) Hara which excerpts from 'Chinese materia medica', and is known to have 'clear heat phlegm' properties in the folk. Little is known about the biological functions and mechanisms of Rosthorin A in cancer cells at present. The role of EMT in metastasis of a tumor cell is self-evident. Slug is an important EMT inducer, which is related to the development of lung cancer. Cell growth, clone assay, cell migration, cell invasion, and protein expression, and NSCLC transplanted tumor growth were performed in A549, H1299, and H1975 cells. Rosthorin A significantly inhibited the growth of NSCLC cells, it could prolong the survival of nude mice. Rosthorin A inhibited the migration and invasion of A549, H1299, and H1975 cells. Rosthorin A up-regulated E-cadherin expression level and down-regulated the expression of β-catenin, N-cadherin, vimentin, Slug, and Twist. Rosthorin A could promote the expression of E-cadherin and inhibit the development of EMT by downregulating Slug, to inhibit the development and metastasis of NSCLC cells. In summary, Rosthorin A could be used as a promising candidate for the treatment of NSCLC patients with recurrence and metastasis.

To demonstrate the efficacy of a protocol combining surgical excision and high-dose-rate brachytherapy for treatment of keloids.

The authors performed a unicentric retrospective cohort study between 2013 and 2018. The minimum follow-up was 12 months. All patients treated for keloids at the authors' institution were included. Extralesional excision was performed with placement of a brachytherapy sheath under the skin. The total dose of irradiation was 18 Gy. The postoperative results were evaluated for aesthetic and functional outcomes with a validated scale, as well as the presence or absence of recurrence.

Fifteen patients were lost to follow-up. Thirty-eight patients with 67 keloids were included. The control rate was 94%. The aesthetic and functional outcomes were considered good in 62% of cases. The main limitation of the study was the small patient population.

Extralesional excision combined with postoperative high-dose-rate brachytherapy seems to be one of the most effective invasive protocols to treat and prevent keloids.
