There is limited information about outcomes associated with stopping asthma biologics.

To compare outcomes in people who stopped or continued asthma biologics.

We identified a cohort of people with asthma who stopped or continued asthma biologics in the Optum Labs Database Warehouse, using a propensity matching method for case and control groups with the variables of age, sex, race, region, insurance, income, specialist access, Charlson comorbidity, specific medical conditions, pre-index exacerbation count, pre-index rescue inhaler pharmacy fills, and pre-index inhaled corticosteroid with or without long-acting β-agonist pharmacy fills. Primary outcome used to assess failure of stopping was an increase of 50% or more in the asthma exacerbation rate in the 6 months after discontinuing the biologic compared with the 6-month period before biologic initiation.

Among a cohort of 4960 asthma biologic users, 1249 were observed to stop use after 6 to 12 months of use. We identified a matched cohort of 1247 stoppers and 1247 people who continued biologic use for at least 18 months. In the first 6 months after stopping or sham stopping, 10.2% of stoppers and 9.5% of continuers had an increase of 50% or more in asthma exacerbations. We found a similar adjusted odds of failing among stoppers and continuers (odds ratio= 1.085; 95% confidence interval, 0.833-1.413).

An increase in asthma exacerbations is infrequently observed in people who stopped asthma biologics and was observed at similar rates as in matched controls who continued asthma biologics.

Multiple randomized, double-blind, placebo controlled clinical trials have evaluated the efficacy and safety of SLIT for asthma. These data provide a good platform to appraise the evidence critically to evaluate the effect of SLIT in the management of asthma for the administration of SLIT by both SLIT drops and SLIT tablets, from a clinical perspective. In this clinical review, presented in a pro and con format, we examined (1) evidence from systematic reviews and meta-analyses; (2) clinical efficacy on asthma symptoms, asthma exacerbations, and quality of life; (3) clinical efficacy on reduction of asthma controller medication; (4) asthma severity; (5) safety profile; (6) long-term effect and prevention; (7) international guidelines, and (8) real-world evidence. Identified inconsistency in the data results from wide variations and differences in outcome measures, specific allergens, delivery approaches, schedules, and age groups. The house dust mite SLIT tablet demonstrated efficacy when it was used in the add-on management of house dust mite-associated allergic asthma in adults. Sublingual allergen immunotherapy for asthma may represent an important advance in incorporating a personalized medicine approach for patients with allergic asthma.
The COVID-19 pandemic has resulted in significant changes to healthcare systems which impact the delivery of surgical training. This study aimed to investigate the qualitative impact of COVID-19 on surgical training in the United Kingdom (UK) & Republic of Ireland (ROI) METHODS This national, collaborative, cross-sectional study involving 13 surgical trainee associations distributed a pan-surgical specialty questionnaire on the impact of COVID-19 on surgical training over 4 weeks in May 2020. Various aspects of training were assessed.

810 completed responses were analysed (males = 401, females = 390) from all deaneries and training grades. The perceived negative overall impact of the pandemic on surgical training experience was significant. (Weighted average = 8.66). PF-06650833 inhibitor 41% of respondents (n = 301) were redeployed with 74% redeployed for >4 weeks. Complete loss of training was reported in elective operating (69.5%), outpatient activity (67.3%) and endoscopy (69.5%). A reduction of >50% was reported level is required.
The Sofia catheter is a new large-bore aspiration catheter that allows easy access and good reperfusion. In this study, we analyzed the efficacy and safety of the Sofia catheter in comparison with stent retrievers as a contact aspiration thrombectomy (CAT) tool for large vessel occlusion.

We enrolled patients with acute ischemic stroke who underwent endovascular thrombectomy from April 2017 and April 2020 in our hospital. Patients wereretrospectively reviewed and divided into the stentretriever group (SR), the Sofia group, and all cases group.

A total of 114 patients were treated during the study period, including 27 in the stent retriever group and 15 in the Sofia group. Higher rates of the first-pass effect (FPE) (37% vs. 47%, P= 0.12) and significantly higher modified FPE (44% vs. 67%, P= 0.001) were observed in patients with SR and Sofia, respectively. Functional independence (modified Rankin Scale ≤2) at 30 days after onset was observed in 30% versus 47% (P= 0.47) of SR and Sofia, respectively.

The Sofia Plus is a large-bore aspiration catheter with high FPE and good accessibility. Use of this catheter resulted better angiographic outcome compared with the stent retriever, but there was no difference in clinical outcomes in this study. Further studies are needed to compare in new generation aspiration catheters.

Deep brain stimulation (DBS) of the mesencephalic locomotor region (MLR) has been studied as a therapeutic target in rodent models of stroke, parkinsonism, and spinal cord injury. Clinical DBS trials have targeted the closely related pedunculopontine nucleus in patients with Parkinson's disease as a therapy for gait dysfunction, with mixed reported outcomes. Recent studies suggest that optimizing the MLR target could improve its effectiveness.

We sought to determine if stereotaxic targeting and DBS in the midbrain of the pig, in a region anatomically similar to that previously identified as the MLR in other species, could initiate and modulate ongoing locomotion, as a step towards generating a large animal neuromodulation model of gait.

We implanted Medtronic 3389 electrodes into putative MLR structures in Yucatan micropigs to characterize the locomotor effects of acute DBS in this region, using EMG recordings, joint kinematics, and speed measurements on a manual treadmill.

MLR DBS initiated and augmented locomotion in freely moving micropigs.
