A non-punitive debriefing model is essential for enhancing student engagement and motivating improved performance in follow-up simulation learning sessions. If nurse educators stay open and responsive to the learning needs of mature students, the advantages of learning through simulation can be realised fully.Resistance to chemotherapeutic agents remains a major challenge in the fierce battle against cancer. Cancer stem cells (CSCs) are a small population of cells in tumors that possesses the ability to self-renew, initiate tumors, and cause resistance to conventional anticancer agents. Targeting this population of cells was proven as a promising approach to eliminate cancer recurrence and improve the clinical outcome. CSCs are less susceptible to death by classical anticancer agents inducing apoptosis. CSCs can be eradicated by ferroptosis, which is a non-apoptotic-regulated mechanism of cell death. The induction of ferroptosis is an attractive strategy to eliminate tumors due to its ability to selectively target aggressive CSCs. The current review critically explored the crosstalk and regulatory pathways controlling ferroptosis, which can selectively induce CSCs death. In addition, successful chemotherapeutic agents that achieve better therapeutic outcomes through the induction of ferroptosis in CSCs were discussed to highlight their promising clinical impact.Sterols serve structural and physiological roles in insects. However, insects and other arthropods have lost many genes in the sterol biosynthesis pathway, so they must acquire sterols from their food. selleck chemicals Sterols occur naturally as free (unconjugated) molecules, and as conjugated ones (mostly steryl esters). Once sterols are ingested and make their way into the gut, steryl esters can be converted into free sterols by Magro protein, a lipase excreted by enterocytes. Sterols in the free form enter midgut enterocytes through NPC1b and are then transported to the smooth endoplasmic reticulum membrane for possible metabolism. For most insect herbivores, phytosterol dealkylation converts plant sterols into cholesterol. Some ingested sterols may also be consumed by microbiota dwelling inside the insect gut lumen; bacteria use sterols as a source of carbon and energy. Further studies will reveal interesting and exciting discoveries regarding the pathways for the dietary sterols entering the insect alimentary canal.

Gamma Knife surgery has become an accepted treatment for small to medium‑size vestibular schwannoma with a high rate of tumor control and good clinical outcome. When GKS treatment fails to stop tumor growth, GKS retreatment can be proposed in selected cases. This retrospective study examines the clinical and tumor control outcome after the second GKS retreatment for the same vestibular schwannomas.

A total of 14 consecutive vestibular schwannomas patients retreated with 2nd GKS were included The median time interval between GKS treatments was 44 months, and the median follow‑up duration after last GKS retreatment was 60 months. The median marginal dose used for the first and second treatments was 12 Gy. The median tumor volume at the initial GKS was 2.4cc (range 0.27-3.8) and was 3.8cc (range 1.21-7.6) at the GKS retreatment.

At the last follow‑up, 93% (13 patients) had tumor growth control, decreased in 4, remained unchanged in 9, and increased tumor size in one patient. New facial or severe trigeminal palsy did not occur after the second GKS retreatment. The hearing was not preserved except in one patient post-GKS retreatment.

GKS retreatment after the failure of initial GKS to control vestibular schwannomas growth appears to be an effective strategy and can be proposed as an alternative to microsurgery when the tumor volume remains within the usual radiosurgical range.

A thorough follow-up study in which the same clinic presents the change in the surgical outcomes of acromegaly over the years, is still lacking in the endoscopic era. In this study, we intended to evaluate the clinical characteristics, radiological features, surgical and late remission rates of newly diagnosed acromegaly patients treated in our clinic between 2014 and 2019 in order to delineate the surgical remission status according to radiological, microscopic, and hormonal features. As a follow-up to our initial report, we also aimed to display the change of surgical remission rates over time in a tertiary center.

A total of newly diagnosed 106 patients with acromegaly, who underwent endoscopic endonasal trans-sphenoidal approach (EETSA) in the last five years were retrospectively analyzed and presented in this study. Medical records were reviewed in clinical, biochemical, pathological, and radiological aspects to assess the relationship of preoperative patient characteristics with surgical remissions.erm late remissions via a multidisciplinary approach.

The presented surgical results are considerably better than our published initial series of acromegaly patients operated in the same clinic between 2007 and 2014. The improvement in surgical remission rate support a positive surgical volume – remission rate relationship for acromegaly in the era of endoscopic endonasal skull base approaches. One possible factor for better results may be the increasing surgical experience in EETSA, which follows a trend toward gradual improvement of long-term late remissions via a multidisciplinary approach.In the wake of the pandemic COVID-19 and nationwide lockdowns gripping many countries globally, the national healthcare systems are either overwhelmed or preparing to combat this pandemic. Despite all the containment measures in place, experts opine that this novel coronavirus is here to stay as a pandemic or an endemic. Hence, it is apt to be prepared for the confrontation and its aftermath. From protecting the vulnerable individuals to providing quality care for all health conditions and maintaining essential drug supplies, it is going to be a grueling voyage. Preparedness to sustain optimal care for each health condition is a must. With a higher risk for severe COVID-19 disease in infants, need of high-dose hormonal therapy with a concern of consequent severe disease, presence of comorbidities, and a need for frequent investigations and follow-up; children with West syndrome constitute a distinctive group with special concerns. In this viewpoint, we discuss the important issues and concerns related to the management of West syndrome during COVID-19 pandemic in the South Asian context and provide potential solutions to these concerns based on the current evidence, adeptness, and consensus.
