Repeated measures ANCOVA suggested participants performed significantly better on laboratory and 3D stations compared to 2D stations. Moderate to severe cybersickness symptoms were reported by 63% of participants in at least one category while using the VRBR application. Highest reported symptoms included eye strain, general discomfort, difficulty focusing, and difficulty concentrating. Overall, the VRBR application is a promising tool for its portability, affordability, and accessibility. Due to reported cybersickness and other technical limitations, the use of VRBR as an alternative to cadaveric specimens presents several challenges when testing anatomy knowledge that must be addressed before widespread adoption.The liver is the primary organ responsible for drug detoxification. Drug-induced liver injury (DILI) is a leading cause of attrition during drug development and is one of the main reasons that drugs are withdrawn from the market. Hence, the prevention of DILI plays a central role in the overall drug-discovery process. Most of the liver's energy supply comes in the form of adenosine triphosphate (ATP), which is largely generated by mitochondria. This article describes the evaluation of drug-induced mitochondrial dysfunction using the Seahorse Extracellular Flux Analyzer (Agilent). The described protocols detail the accurate measurement of ATP production rate in HepG2 cells after exposure to a panel of potentially toxic compounds. This assay measures changes in extracellular acidification rate (ECAR) and oxygen consumption rate (OCR) as indicators of glycolysis and mitochondrial respiration-the two major energy-generating pathways in a cell. This assay provides a useful model to predict mitochondrial dysfunction-mediated DILI. © 2021 Wiley Periodicals LLC.

Pouchitis is a condition with large unmet medical needs and no approved therapies. Lack of validated instruments to measure disease activity and treatment response is a major barrier to drug development.

To conduct a modified RAND/University of California Los Angeles appropriateness process to produce a standardised assessment of pouchitis disease activity in clinical trials.

A list of 164 items generated upon a systematic review and expert opinion were rated based on a 9-point scale (appropriate, uncertain and inappropriate), by a panel including 16 gastroenterologists, surgeons and histopathologists.

Items rated as appropriate to evaluate in pouchitis clinical trials were (a) clinical stool frequency and faecal urgency; (b) endoscopic primary assessment in the pouch body according to the percentage of affected area (<50%, 50%-75% and >75%), evaluation of the presence of ulcers/erosions according to size (erosions <5mm, ulcers ≥5mm to 2cm and large ulcers >2cm) and ulcerated area (<10%, 10%-30% and >30%); (c) histologic two biopsies from each segment, from the ulcer's edge when present, or endoscopically normal areas, assessment of lamina propria chronic inflammation, epithelial and lamina propria neutrophils, epithelial damage, erosions and ulcers; and (d) clinical trial inclusion/outcome criteria minimum histologic disease activity for inclusion, a primary endpoint based on stool frequency and assessment of clinical, endoscopic and histologic response and remission. The overall majority of items surveyed (100/164) were rated 'uncertain'.

We conducted a RAND/UCLA appropriateness process to help inform measurement of pouchitis disease activity within clinical trials and foster the development of novel therapies.

To describe the application of a big data science framework to develop a pain information model and to discuss the potential for its use in predictive modeling.

This is an application of a cross-industry standard process for a data mining adapted framework (the Applied Healthcare Data Science Framework) to build an information model on pain management and its potential for predictive modeling. Data were derived from electronic health records and were composed of approximately 51,000 records of unique adult patients admitted to clinical and surgical units between July 2015 and June 2019.

The application of the Applied Healthcare Data Science Framework steps allowed the development of an information model on pain management, considering pain assessment, interventions, goals, and outcomes. The developed model has the potential to be used for predicting which patients are most likely to be discharged with self-reported pain.

Through the application of the framework, it is possible to support health professionals' decision making on the use of data to improve the effectiveness of pain management.

In the long term, the framework is intended to guide data science methodologies to personalize treatments, reduce costs, and improve health outcomes.

The phosphodiesterase inhibitors theophylline and pentoxifylline have anti-inflammatory properties that may make them useful in COVID-19 pneumonia. We conducted a retrospective review of hospitalized COVID-19 patients requiring oxygen who received these drugs.

To examine the potential efficacy and safety of theophylline and pentoxifylline in COVID-19 pneumonia patients.

Adults with a positive test for SARS-COV2 and were hospitalized due to pneumonia requiring either high flow nasal cannula or mechanical ventilation were included. Patients with a history of asthma or chronic obstructive pulmonary disease were preferentially given theophylline. All other patients received pentoxifylline 400mg orally TID. A group of hospitalized COVID-19 patients receiving standard of care acted as a comparison group. The coprimary outcomes were a change in C-reactive protein (CRP) and ROX score between groups from day 1 to day 4 of therapy.

Two hundred and nine inpatients were reviewed. Fifty-eight patients received pentoxifylline/theophylline, with 151 patients serving as the comparison group. Active therapy was associated with an increase in the ROX score (mean 2.9 (95% CI 0.6, 5.1)) and decrease in CRP (mean -0.7 (95% CI -4.7, 3.2). Mortality rates were theophylline/pentoxifylline 24% and comparison group had a 26%, respectively.

In this retrospective study, theophylline and pentoxifylline were associated with an increase in ROX score and nominal decreases in CRP and mortality. Treatment was safe with few adverse reactions documented. We believe that this study could the basis for randomized-controlled trials to further explore these drugs' role in COVID-19.

Trastuzumab can significantly prolong the survival of patients with human epidermal growth factor receptor-2 (HER-2)-positive breast cancer. Trastuzumab-induced thrombocytopenia is a rare adverse effect. There have been no reports of acute, grade 4 thrombocytopenia after weekly trastuzumab therapy. The study reports a case of a breast cancer patient with severe thrombocytopenia due to trastuzumab infusion (8mg/kg). Moreover, the patient experienced recurrence of severe thrombocytopenia after receiving weekly trastuzumab therapy (4mg/kg).

A 52-year-old woman with HER-2-positive breast cancer developed diffuse petechial haemorrhages and ecchymosis on the lower limbs and gingival bleeding within 24 hours of trastuzumab infusion (8mg/kg). She was confirmed to have severe thrombocytopenia, which quickly recovered after corticosteroid therapy and platelet transfusion. When her platelet count recovered, we attempted weekly trastuzumab therapy (4mg/kg); however, thrombocytopenia recurred within 24 hours. Thus, we did not attempt further treatment with trastuzumab.

We are the first to attempt weekly trastuzumab therapy after thrombocytopenia induced by its initial administration. Reducing the trastuzumab dose did not prevent trastuzumab-induced thrombocytopenia. Unlike other reports with administration of high-dose corticosteroid, we found that a standard dose of corticosteroid combined with platelet transfusion was effective in treating trastuzumab-induced thrombocytopenia.

However, the expression of PD-L1 on bone marrow mesenchymal stem cells (BMSCs) and whether the programmed cell death 1 (PD-1)/PD-L1 signal pathway is involved in the BMSCs versus T cell immune response in multiple myeloma (MM) remains poorly defined. In this study, we explored the expression of PD-L1 on BMSCs from newly diagnosed MM (NDMM) patients and the role of PD-1/PD-L1 pathway in BMSC-mediated regulation of CD8+ T cells. The data showed that the expression of PD-L1 on BMSCs in NDMM patients was significantly increased compared to that in normal controls (NC) (18·81 ± 1·61 versus 2·78± 0·70%; P less then 0·001). Furthermore, the PD-1 expression on CD8+ T cells with NDMM patients was significantly higher than that in normal controls (43·22 ± 2·98 versus 20·71 ± 1·08%; P less then 0·001). However, there was no significant difference in PD-1 expression of CD4+ T cells and natural killer (NK) cells between the NDMM and NC groups. Additionally, the co-culture assays revealed that BMSCs significantly suppressed CD8+ T cell function. However, the PD-L1 inhibitor effectively reversed BMSC-mediated suppression in CD8+ T cells. We also found that the combination of PD-L1 inhibitor and pomalidomide can further enhance the killing effect of CD8+ T cells on MM cells. In summary, our findings demonstrated that BMSCs in patients with MM may induce apoptosis of CD8+ T cells through the PD-1/PD-L1 axis and inhibit the release of perforin and granzyme B from CD8+ T cells to promote the immune escape of MM.
Local anaesthesia (LA) administration provokes dental anxiety in children. BrightHearts is a biofeedback relaxation application designed to reduce anxiety in children during painful procedural interventions.

To compare the effectiveness of biofeedback relaxation (BR) and audio-visual (AV) distraction on dental anxiety among 7- to 12-year-old children while administering LA.

A total of 70 children requiring dental treatment under LA for three visits were recruited for this single-blinded randomized control trial. 8-OH-DPAT clinical trial They were randomly divided into two equal groups. Group A received BR and Group B received AV distraction during LA delivery in the first two visits, and both groups did not receive any intervention during LA in third visit. Outcomes were measured using heart rate and a cartoon-based anxiety measuring scale (Chotta Bheem-Chutki (CBC) scale).

AV group had statistically significant higher mean heart rates than BR group (P<.001) during needle penetration and post-intervention, respectively. CBC scale showed no statistical differences between the groups.
