The purpose of this study is to develop a machine learning algorithm to predict future intubation among patients diagnosed or suspected with COVID-19.

This is a retrospective cohort study of patients diagnosed or under investigation for COVID-19. A machine learning algorithm was trained to predict future presence of intubation based on prior vitals, laboratory, and demographic data. Model performance was compared to ROX index, a validated prognostic tool for prediction of mechanical ventilation.

4087 patients admitted to five hospitals between February 2020 and April 2020 were included. 11.03% of patients were intubated. The machine learning model outperformed the ROX-index, demonstrating an area under the receiver characteristic curve (AUC) of 0.84 and 0.64, and area under the precision-recall curve (AUPRC) of 0.30 and 0.13, respectively. In the Kaplan-Meier analysis, patients alerted by the model were more likely to require intubation during their admission (p<0.0001).

In patients diagnosed or under investigation for COVID-19, machine learning can be used to predict future risk of intubation based on clinical data which are routinely collected and available in clinical setting. Such an approach may facilitate identification of high-risk patients to assist in clinical care.

Sentinel node (SN) assessment via frozen section (FS) has declined since the publication of Z0011 which modified the management of a specific group of patients with positive SN. The risk of misleading the surgeons to a preventable ALND and the cost are among the main factors for that. The aim of our study is to assess the value of FS in the post Z0011.

244 patients out of 434 were eligible for an upfront SLNB. Based on the final histology and the clinical data we selected the eligible for breast conserving surgery patients (55.4%). 78 patients had positive SN and 26 of them fulfilled the criteria of Z0011. We assessed the false negative findings, the impact on the management and the indications and value of FS in the post Z0011 era.

Overall, there were 12 F N cases out of which 7 were macrometastases (8.97%). Only in one case there were > 2 positive LN and 3 patients needed mastectomy. The remaining cases fulfilled the criteria of Z0011 and needed no further surgery hence in 96.1% of the cases the axillary status was correctly assessed via FS and the reoperation rate was 1.2%. On the contrary, if FS was not used, at least 21.3% of the patents would have needed reoperation based on the today's guidelines.

We believe FS is still valuable and may spare a significant percentage of patients from a second operation (SNB) without leading to axillary overtreatment if used wisely.

In this study, we evaluated the function of microRNA-211-5p (miR-211-5p) on SCI in a rat model. SCI model was established using modified Allen's weight-drop method and Basso-Bcattie-Bresnahan score was applied to assess the locomotor function. MiR-211-5p agomir was utilized to increase miR-211-5p expression and endoplasmic reticulum (ER) stress inhibitor, 4-PBA (4-phenylbutyric acid), was utilized to suppress ER stress. Neuron apoptosis and the expressions of miR-211-5p, activating transcription factor 6 (ATF6), apoptosis-related proteins, pro-inflammatory cytokines and endoplasmic reticulum stress-related proteins were detected. Dual luciferase reporter gene assay was performed to verify the binding between miR-211-5p and ATF6. The results showed that miR-211-5p directly targeted ATF6. MiR-211-5p was down-regulated and ATF6 was up-regulated in SCI rats. Both interferences with miR-211-5p agomir and 4-PBA effectively attenuated neuron apoptosis and reversed the expressions of apoptosis, inflammation and endoplasmic reticulum stress-related molecules post SCI in rats. These findings demonstrated that miR-211-5p could effectively alleviate SCI-induced neuron apoptosis and inflammation via directly targeting ATF-6 and regulating ER stress.Cystic echinococcosis (CE) is caused by the cestodes of the Echinococcus granulosus sensu lato complex and, in the majority of cases, is associated with hepatic or pulmonary involvement. Human CE is not thought to be endemic in Ireland. check details We describe the first reported case of human CE possibly acquired in Ireland.Curcumin (Cur) is a natural polyphenolic flavonoid isolated from the rhizomes of Curcuma longa. Its anti-inflammatory and cardioprotective properties are increasingly considered to have beneficial effects on the progression of cardiomyopathy associated with Chagas disease, caused by Trypanosoma cruzi. However, the Cur therapeutic limitation is its bioavailability and new Cur nanomedicine formulations are developed to overcome this obstacle. In this research, we provide evidence showing that oral therapy with a suboptimal dose of the standard parasiticidal drug benznidazole (BZ) in combination with Cur-loaded nanoparticles is capable of reducing myocardial parasite load, cardiac hypertrophy, inflammation and fibrosis in mice with long-term infection by T. cruzi. Treatment with BZ plus Cur was highly effective in downregulating myocardial expression of proinflammatory cytokines/chemokines (IL-1β, TNF-α, IL-6, CCL5), and the level/activity of matrix metalloproteinases (MMP-2, MMP-9) and inducible enzymes (cyclooxygenase, nitric oxide synthase) implicated in leukocyte recruitment and cardiac remodeling. Oral administration of a Cur-based nanoformulation displays potential as a complementary strategy to the conventional BZ chemotherapy in the treatment of chronic Chagas heart disease.
