Adolescent pain is common and continues into adulthood, leading to negative long-term outcomes including substance-related morbidity an empirical definition of its construct may inform the early detection of persistent pain trajectories. These secondary analyses of a classical twin study assessed whether headaches, back pains, abdominal pain, chest pains, stabbing/throbbing pain, gastric pain/nausea, measured in 501 pairs across 5 waves between age 12-17, fit a unitary construct, or constitute independent manifestations. We then assessed which symptoms were associated with a steady, 'frequent pain' trajectory that is associated with risk for early opioid prescriptions. Item Response Theory results indicated that all 6 pain symptoms index a unitary construct. Binary logistic regressions identified 'back pain' as the only symptom consistently associated with membership in the 'frequent adolescent pain' trajectory (OR1.66-3.38) at all 5 measurement waves. Receiver Operating Characteristic analyses computed thee cut-off thresholds of symptom frequency, 'back pain' showed good sensitivity/false alarm probability trade-offs, predominantly in the 13-14-15 age range, to predict the 'frequent pain' trajectory. These data support a unitary conceptualization and assessment of adolescent pain, which is advantageous for epidemiological, clinical, and translational purposes. Persistent back pain constitutes a sensitive indicator of a steady trajectory of adolescent pain.
Emerging literature continues to demonstrate the use of innovative practices such as simulated-based learning experiences to prepare students for professional placements. This scoping review aimed to provide a broad overview of how simulated-based learning experiences have been implemented within or immediately before the professional practice placements of entry-level allied health programs. Four databases (MEDLINE, EMCARE, CINAHL, and Scopus) were searched up to August 2020. Kirkpatrick's evaluation framework was used to categorize outcomes, and the Simulation-Based Research Extension for the CONSORT statement was used to appraise the quality of simulation reporting. The search revealed 6584 unique abstracts with 321 full-text articles reviewed. Forty-eight studies met the inclusion criteria. This review has shown a clear trend toward using simulation within or immediately before the professional practice placements of allied health programs. Using Kirkpatrick's evaluation framework, most studies reportede clinical environment. In addition, more consistent reporting of simulation methodologies and evaluation methods are needed to strengthen the evidence base.
As simulation matures, it is critical to develop pathways for researchers. A recent analysis, however, demonstrates a low conversion rate between abstract and peer-reviewed journal publication in our field. The International Network for Simulation-based Pediatric Innovation, Research, and Education has used the ALERT Presentation process for the past decade as a means of accelerating research. In this study, we analyze the scholarly products attributable to ALERT Presentations.

Surveys were distributed to all International Network for Simulation-based Pediatric Innovation, Research, and Education Advanced Look Exploratory Research Template (ALERT) Presentation first authors from January 2011 through January 2020. Presenters were asked to provide information on abstracts, grants, journal publications, and book chapters related to their ALERT Presentation, as well as basic demographic information. A structured literature search was conducted for those ALERT Presentations whose authors did not return a surveship. Wider adoption may benefit other simulation and education research networks.
There is evidence in the literature for high-fidelity in situ simulation training programs being an effective modality for physicians training. This quality initiative focused on implementation of the procedural sedation and analgesia (PSA) in our pediatric emergency department (PED). The primary outcomes of this study were to evaluate the impact of blended in situ simulation training (BST) program on PSA for closed forearm fracture reduction in the PED and to assess its cost-effectiveness. The secondary outcomes were to estimate this change on PSA's clinical efficacy and safety.

Between 2014 and 2018, a single-center, quasi-experimental, uncontrolled before and after study on forearm fracture reduction management was conducted. To assess the impact of our BST-PSA course, both historical control and prospective analyses were performed. Statistical significance was based on Fisher exact test or Pearson χ2 test.

Eight hundred eighty-five children met inclusion criteria. A significant difference in the number of PSAs performed in the PED, before and after BST, was found (37% vs. 85.3%, P < 0.001). Furthermore, a reduction in the number of hospitalizations for closed fracture reduction was measured (68.2% vs. 31.8%, P < 0.001). The overall cost savings from the BST-enabled increase in PSAs carried out in the PED was €370,714 ($440,838) with a return on investment of 641. No significant increase of PSA-related adverse events was found, and no serious adverse events occurred.

Findings provide evidence of the benefits of implementing BST to enable PSA use in the PED, with an improved patient flow and significant cost savings from avoiding unnecessary hospitalizations.

Previous studies have shown that methamphetamine (METH) can induce complex adaptive changes in the reward system in the brain, including the changes in the content of neurotransmitters in the signal transduction pathway. However, how the changes of various neurotransmitters in relevant brain reward circuits contribute to METH-induced conditioned place preference (CPP) remains unclear.

In this study, first, we designed an animal model of METH-induced CPP. Then we used liquid chromatography-mass spectrometry (LC-MS) to simultaneously determine the contents of various neurotransmitters - dopamine (DA), norepinephrine (NE), 5-hydroxytryptamine (5-HT), 5-hydroxyindole acetic acid (5-HIAA), glutamic acid (Glu) and glutamine (Gln) - in different brain regions of the prefrontal cortex (PFc), nucleus accumbens (NAc), caudate-putamen (CPu) and hippocampus (Hip), which are believed to be relevant to the drug's reward effect.

The results of the behavioral experiment suggested that 1.0 mg/kg METH could induce obvioueffect, which is important for future improvements in the treatment of drug addiction.
Venetoclax is a BCL-2 inhibitor that was approved in combination therapy with hypomethylating agents or low dose cytarabine for newly diagnosed acute myeloid leukemia (AML). The purpose of this review is to outline the most recent venetoclax-based combination therapies in newly diagnosed or relapsed myelodysplastic syndrome (MDS) and AML patients.

Venetoclax has been incorporated in various therapeutic regimens - either with chemotherapy, immunotherapy or targeted therapies. These combinations achieve high remission rates with deep molecular responses, as suggested by measurable residual disease measurements. There are concerns regarding the incomplete count recovery, prolonged cytopenia and infection rates, especially when combined with chemotherapy. There is also limited data concerning durability of these remissions, and the effectiveness in high-risk population (i.e. p53-mutated AML patients).

Venetoclax-based combination therapies encompass novel therapeutic possibilities in MDS and AML with encouraging initial results. However, the exact role of each combination therapy and the long-term effects on patients' outcome are yet to be defined.

Melanocytic nevi submitted to trauma can undergo clinical, dermoscopic, and even histological changes, making it difficult to differentiate them from a melanoma.

The aim of this study is to evaluate the dermoscopic changes of traumatized nevi after dermabrasion.

Dermoscopic images of acquired melanocytic nevi were compared before and 4 weeks after half of their area had undergone dermabrasion.

The sample consisted of 50 lesions from 15 patients. The homogeneous pattern was the most frequent, followed by the reticular, cobblestone, and globular patterns. After dermabrasion, nearly half of the lesions (46%) became dermatoscopically asymmetric. Among all lesions, structureless areas, dotted vessels and erythema were the most frequent new dermoscopic structures.

Trauma after dermabrasion may induce significant dermoscopic changes in melanocytic nevi. Although the global pattern did not change, most of the lesions became asymmetric, with the appearance or fading of dermoscopic structures and colors. A history of recent trauma should be investigated when evaluating pigmented lesions.

Perusal of the literature of cutaneous squamous cell carcinoma (SCC) reveals that the role of the desmoplastic subtype is indistinct. Data on local infiltration and recurrence are inconsistent dependent on surgical technique, histological method, and investigated collective.

The aim of the study was to analyze local infiltration and locoregional recurrence of the desmoplastic subtype under a uniform procedure.

Between 2005 and 2015, 320 SCCs were analyzed and histological sections of all tumors were examined. Data collection included locoregional recurrence, metastasis rate, and tumor-specific death. CRT-0105446 molecular weight The median follow-up was 36.5 months.

The desmoplastic subtype required significant more re-excisions (70.0% vs 23.9%, p < .001), more interventions until tumor-free margins were achieved (maximal 6 vs 2; p < .001), showed more widespread tumor infiltration with larger excisional margins (median 9 mm, 2-51 mm vs median 4 mm, 1-10 mm; p < .001), and a 5-fold higher local recurrence rate (26.7% vs 5.0%, p < .001). The metastasis rate (16.6% vs 2.3%, p < .001) was increased.

The desmoplastic subtype is characterized by a widespread local infiltration associated with perineural infiltration. It seems to be a marker for decreased histological detectability with a high rate of locoregional recurrence and metastasis.
