Recently, there is an increased number of reports being published on Methotrexate (MTX) related cutaneous manifestations. We aimed to identify and critically appraise descriptive studies describing the MTX related skin manifestations, treatment approach, and their outcomes.

An extensive literature search was performed in the PubMed, Embase, and Scopus databases from inception to April 2021 without any restrictions along with the bibliographic search of included studies, grey literature search, and a snowball search was performed in Google and Google Scholar to identify the relevant literature. Descriptive studies reporting MTX related cutaneous manifestations were considered for the review. The study selection, data extraction, and quality assessment were conducted by two independent reviewers and any disagreements were settled by consensus with the third reviewer.

31 out of 8,365 descriptive studies including 38 patients (22 females and 16 males) aged between 12 and 78years prescribed for the management of rheumatoid arthritis, ankylosing spondylitis, and psoriasis were included in this review. Toxic epidermal necrolysis (TEN), papular eruption, vasculitis, erosions of psoriasis, ulcerated psoriatic plaques, local reactions, keratinocyte dystrophy, erythema multiforme, drug rash with eosinophilia and systemic symptoms, Steven Johnson syndrome and photosensitive dermatitis were the majority of MTX induced cutaneous reactions. Immediate withdrawal of MTX, providing appropriate care with anti-inflammatory, topical steroids, and supplementation with folic acid were reported to be effective for the management of the MTX related cutaneous manifestations.

Clinicians and healthcare professionals should be aware of possible acute cutaneous drug reactions induced by MTX to avoid further consequences and fatal conditions. Immediate withdrawal of MTX and supportive care were reported as an efficacious therapeutic management of acute cutaneous drug reactions.

CRD42020220038.The dense and heterogeneous physical network of the extracellular matrix (ECM) in tumors represents a formidable barrier that limits intratumor drug delivery and the therapeutic efficacy of many anticancer therapies. Here, the two major nanomedicine strategies to circumvent intratumor ECM barriers regulating the physiochemical properties of nanomedicines and remodeling the components and structure of the ECM are summarized. Nanomedicines can be rationally regulated by optimizing physiochemical properties or designed with biomimetic features to promote ECM permeation capability. Meanwhile, they can also be designed to remodel the ECM by modulating signaling pathways or destroying the components and architecture of the ECM via chemical, biological, or physical treatments. These efforts produce profound improvements in intratumor drug delivery and anticancer efficacy. Moreover, to aid in their anticancer efficacy, feasible approaches for improving ECM-circumventing nanomedicines are proposed.
Obesity is protective of bone health; however, abdominal obesity is associated with a higher fracture risk. Little is known about whether body composition protects or adversely affects osteoporotic fractures because of practical issues regarding assessment tools. This study aimed to evaluate the association of predicted body composition with fracture risk to determine the distinctive and differing effects of muscle or fat mass on bone health outcomes in the general population.

This population-based, longitudinal cohort study used 2009-2010 Korean National Health Insurance Service data and follow-up data from 1 January 2011 to 31 December 2013, to determine the incidence of osteoporotic fracture (total, spine, and non-spine) defined using the International Classification of Diseases, Tenth Revision codes. The study participants were aged ≥50years (men, 158426; women, 131587). selleckchem The predicted lean body mass index (pLBMI), appendicular skeletal muscle index (pASMI), and body fat mass index (pBFMI) were used toeater in men and reduced the risk of spinal fractures. An increased pBFMI was associated with an increased risk of spinal fractures in women.

An increased pLBMI or pASMI was significantly associated with decreased total osteoporotic fracture risk; however, the pBFMI showed no statistically significant association. Muscle mass was more important than fat mass in preventing future osteoporotic fractures based on anthropometric prediction equations.

The use of immersive virtual reality simulated learning environments (VR SLEs) for improving clinical communication can offer desirable qualities including repetition and determinism in a safe environment. The aim of this study was to establish whether the mode of delivery, VR SLE versus clinical role-play, could have a measurable effect on clinical empathic communication skills for MRI scenarios.

A split-cohort study was performed with trainee practitioners (n = 70) and qualified practitioners (n = 9). Participants were randomly assigned to four groups clinician VR (CVR), clinician role-play (CRP), trainee VR (TVR), and trainee RP (TRP). Clinical communication skills were assessed using two methods firstly, a self-reported measure - the SE-12 communication questionnaire and, secondly, a training and assessment tool developed by a panel of experts.

Participants in the VR trainee (TVR) and clinician (CVR) groups reported 11% (P < 0.05) and 7.2% (P < 0.05) improvements in communication confidence poon into an emotional narrative in a VR environment to increase the user's susceptibility for recalling and selecting empathic terminology.
To report the arrival ionised calcium (iCa) and fibrinogen concentrations in trauma patients treated with packed red blood cells by the road-based high-acuity response units of a metropolitan ambulance service.

A retrospective review of trauma patients treated with packed red blood cells by high-acuity response units between January 2012 and December 2016. Patients were identified from databases at southeast Queensland adult trauma centres, Pathology Queensland Central Transfusion Laboratory, Gold Coast University Hospital blood bank and the Queensland Ambulance Service. link2 Patient characteristics, results of laboratory tests within 30 min of ED arrival were analysed.

A total of 164 cases were analysed. link3 The median injury severity score was 33.5 (interquartile range 22-41), with blunt trauma the commonest mechanism of injury (n=128, 78.0%). Fifty-eight of the 117 patients (24.4%) with fibrinogen measured had a fibrinogen concentration ≤1.5g/L; 79 of the 123 patients (64.2%) with an international normalised ratio (INR) measurement had an INR >1.2; 97 of 148 patients (63.8%) with an iCa measured, had an iCa below the Pathology Queensland reference range of 1.15-1.32 mmol/L. Arrival fibrinogen concentration ≤1.5g/L and arrival iCa ≤1.00 were associated with in-hospital mortality with odds ratio11.90 (95% confidence interval 4.50-31.65) and odds ratio4.97 (95% confidence interval 1.42-17.47), respectively.

Hypocalcaemia and hypofibrinogenaemia on ED arrival were common in this cohort. Future work should evaluate whether outcomes improve by correction of these deficits during the pre-hospital phase of trauma care.

There is no categorical documentation in the current literature on the precise locations of arterial resistance (R) and compliance (C) in vasculature. Knowledge of their exact locations in the arterial tree enables re-assessment of the differential action of vasoactive drugs on resistance versus compliance vessels once we resolve beat-to-beat changes in R and C in response to these drugs. Isolated goat aortae and small arteries were perfused with a pulsatile pump and lumen pressures were recorded before and after addition of adrenaline. Equivalent electrical models were simulated, and biological data was compared against the electrical equivalents to derive interpretations. In the aortae, systolic pressure increased, diastolic pressure decreased, pulse pressure increased (p = 0.018); but the mean pressure remained the same (p = 0.357). Whereas in small artery, vasoconstriction caused an increase in systolic, diastolic, and mean pressures (p = 0.028). Simulations allow us to infer that vasoconstriction in aorta leads to a reduction in compliance, but an increase in resistance if any, is not sufficient to alter the mean aortic pressure. Whereas vasoconstriction in small arteries increases resistance, but a decrease in compliance if any, does not affect any of the pressure parameters measured. The presented study is first of its kind to give experimental evidence that large arteries and aorta are the only compliance vessels and small arteries are the only resistance vessels.
The impact of electronic health records (EHRs) in the emergency department (ED) remains mixed. Dynamic and unpredictable, the ED is highly vulnerable to workflow interruptions.

The aim of the study is to understand multitasking and task fragmentation in the clinical workflow among ED clinicians using clinical information systems (CIS) through time-motion study (TMS) data, and inform their applications to more robust and generalizable measures of CIS-related documentation burden.

Using TMS data collected among 15 clinicians in the ED, we investigated the role of documentation burden, multitasking (i.e., performing physical and communication tasks concurrently), and workflow fragmentation in the ED. We focused on CIS-related tasks, including EHRs.

We captured 5,061 tasks and 877 communications in 741 locations within the ED. Of the 58.7 total hours observed, 44.7% were spent on CIS-related tasks; nearly all CIS-related tasks focused on
and
. Over one-fifth of CIS-related task time was spent on multt observation techniques (e.g., EHR log files).
Multitasking and workflow fragmentation may play a significant role in EHR documentation among ED clinicians, particularly among data-entering tasks. Understanding where and when multitasking and workflow fragmentation occurs is a crucial step to assessing potentially burdensome clinician tasks and mitigating risks to patient safety. These findings may guide future research on developing more scalable and generalizable measures of CIS-related documentation burden that do not necessitate direct observation techniques (e.g., EHR log files).
Overuse of cardiac telemetry monitoring (telemetry) can lead to alarm fatigue, discomfort for patients, and unnecessary medical costs. Currently there are evidence-based recommendations describing appropriate telemetry use, but many providers are unaware of these guidelines.

At our multihospital health system, our goal was to support providers in ordering telemetry on acute care in accordance with evidence-based guidelines and discontinuing telemetry when it was no longer medically indicated.

We implemented a multipronged electronic health record (EHR) intervention at two academic medical centers, including (1) an order set requiring providers to choose an indication for telemetry with a recommended duration based on American Heart Association guidelines; (2) an EHR-generated reminder page to the primary provider recommending telemetry discontinuation once the guideline-recommended duration for telemetry is exceeded; and (3) documentation of telemetry interpretation by telemetry technicians in the notes section of the EHR.
