Graves' orbitopathy (GO) is the most common extrathyroidal manifestation of Graves' disease (GD), an autoimmune disorder arising from the activity of T lymphocytes against antigens that infiltrate thyroid tissue, orbital tissue and extraocular muscles. An increase in oxidative stress has been discovered in autoimmune thyroid disease, encouraging investigation into new forms of treatment. Selenium has been described as a treatment option given its antioxidant properties. The present study evaluates the decrease of progression and inflammatory signs in patients with mild GO with oral selenium supplementation.

Controlled, randomized, single center trial at an ophthalmology referral center in Mexico City. Patients at least 18years of age with mild GO according to the CAS classification were included; exclusion criteria in addition to corticosteroid treatment included smokers or selenium allergy. MRTX0902 chemical structure Each patient was randomized into one of two groups. Group A took placebo tablets which consisted of 100μg of starch twice a day for 6months, and group B took a 100μg selenium tablet twice a day for 6months. The patients from both groups were examined and evaluated using a CAS score before and after the first, third and sixth month of treatment.

Thirty eyes of 30 patients were studied. The pretreatment values showed no statistically significant differences between groups (P>0.05). Intergroup analysis showed statistically significant differences in palpebral fissure and CAS score between the pretreatment values and six months after treatment in the selenium group (P<0.05). No differences were found in any variables in the placebo group during the study period (P>0.05). No adverse events were reported.

This is the first study in a Mexican population demonstrating that oral selenium decreases clinical activity and stops progression in patients with mild GO.

This risk is highest in those with pre-eclampsia and eclampsia as well as those of Asian descent. Despite this increased risk, pregnancy was an exclusion criterion for major stroke intervention trials. As a result, there are significant challenges concerning the management of this unique patient population. We describe a case of an early first trimester cerebrovascular accident treated with systemic thrombolysis.
We aimed to introduce an explainable machine learning technology to help clinicians understand the risk factors for neonatal postoperative mortality at different levels.

A total of 1481 neonatal surgeries performed between May 2016 and December 2019 at a children's hospital were included in this study. Perioperative variables, including vital signs during surgery, were collected and used to predict postoperative mortality. Several widely used machine learning methods were trained and evaluated on split datasets. The model with the best performance was explained by SHAP (SHapley Additive exPlanations) at different levels.

The random forest model achieved the best performance with an area under the receiver operating characteristic curve of 0.72 in the validation set. TreeExplainer of SHAP was used to identify the risk factors for neonatal postoperative mortality. The explainable machine learning model not only explains the risk factors identified by traditional statistical analysis but also identifies additional risk factors. The visualization of feature contributions at different levels by SHAP makes the "black-box" machine learning model easily understood by clinicians and families. Based on this explanation, vital signs during surgery play an important role in eventual survival.

The explainable machine learning model not only exhibited good performance in predicting neonatal surgical mortality but also helped clinicians understand each risk factor and each individual case.

We reported the in vitro and in vivo anti-tumor effects of trametinib, an MEK inhibitor, on neuroblastoma. However, long-term trametinib administration for bulky tumors failed to prevent local relapse. In this study, we established a local minimal residual disease (L-MRD) model to develop an optimal clinical protocol.

We prepared an l-MRD model by implanting neuroblastoma cells (SK-N-AS) into the renal capsule of nude mice with total tumorectomy or sham operation 14 days later. These mice received post-operative administration of trametinib or vehicle for eight weeks. Relapse was measured once weekly. Flow cytometry was performed with SK-N-AS cells treated by trametinib.

Tumorectomy+trametinib dramatically suppressed relapse, and all mice survived during trametinib administration, while other treatments failed to suppress relapse. The survival rates for other groups were 20% in sham+trametinib, 17% in tumorectomy+vehicle, and 0% in sham+vehicle. Relapse occurred in the tumorectomy+trametinib group after withdrawal of trametinib administration. Flow cytometry revealed G1 arrest in SK-N-AS cells treated with trametinib.

These findings suggested that trametinib was able to suppress relapse from minimal residual tumor cells. Therefore, we propose that trametinib be administered as an option for maintenance therapy after surgical and chemotherapeutic treatments for neuroblastoma in future clinical protocols.

Simultaneous gastrostomy tube (GT) and tracheostomy placement in young children offers potential benefit in limiting anesthetic exposure, but it is unknown whether combining these procedures introduces additional morbidity. This study compared outcomes after combined GT and tracheostomy placement versus GT placement alone among similar ventilator-dependent patients.

Ventilator-dependent children <2-years-old who underwent GT placement alone (MV-GT), simultaneous GT and tracheostomy placement (GT+T), and GT placement alone with a pre-existing tracheostomy (T-GT) were identified using 2012-2018 NSQIP-Pediatric Participant User Files. Multiple logistic regression models were used to compare outcomes while adjusting for other group differences.

Among 1100 children, 351 underwent MV-GT, 494 GT+T, and 255 T-GT. Major complications occurred in 23.6%, 17.0%, and 14.5% of the respective groups (p=0.01). Major complications with GT+T were similar to T-GT (adjusted odds ratio [aOR]=1.19, 95%CI0.78-1.83, p=0.4) and lower than MV-GT (aOR=0.
