To define and evaluate hemodynamic criteria to distinguish between classical orthostatic hypotension (cOH) and vasovagal syncope (VVS) in tilt table testing (TTT).

Inclusion criteria for VVS were a history of VVS and tilt-induced syncope defined as a blood pressure (BP) decrease and electroencephalographic changes during syncope with complaint recognition. Criteria for cOH were a history of cOH and a BP decrease meeting published criteria. Clinical diagnoses were established prior to TTT. We assessed (1)whether the decrease of systolic BP accelerated, "convex," or decelerated, "concave"; (2) the time from head-up tilt to when BP reached one-half its maximal decrease; (3) the difference between baseline heart rate (HR) and HR at BP nadir. We calculated the diagnostic yield of optimized thresholds of these features and their combinations.

We included 82 VVS cases (40% men, median age 44years) and 65 cOH cases (66% men, median age 70years). BP decrease was concave in cOH in 79% and convex in VVS in 94% (p<0.001). The time to reach half the BP decrease was shorter in cOH (median 34sec, interquartile range (IQR) 19-98sec) than in VVS (median 1571sec, IQR 1381-1775sec, p<0.001). Mean HR increased by 11±11bpm in cOH and decreased by 20±19bpm in VVS (p<0.001). When all three features pointed to VVS, sensitivity for VVS was 82% and specificity was 100%. When all three pointed to cOH, sensitivity for cOH was 71% and specificity was 100%.

These new hemodynamic criteria reliably differentiate cOH from VVS.

Posaconazole and itraconazole are commonly used for systemic antifungal prophylaxis after lung transplantation. The aim of this study on critically ill lung transplant recipients was to assess the rate of adequate plasma concentrations and the frequency of fungal-induced transitions from antifungal prophylaxis to therapy after the administration of either posaconazole or itraconazole for systemic prophylaxis.

Critically ill lung transplant recipients with postoperative posaconazole or itraconazole prophylaxis and therapeutic drug monitoring from February 2016 to November 2019 were retrospectively included in the study. Positive fungal cultures or Aspergillus antigen tests resulting in a transition from antifungal prophylaxis to therapy were analyzed from the first day of prophylaxis until 7days after the last sample for each patient. Adequate plasma concentrations were defined as ≥500µg/L for itraconazole and ≥700µg/L for posaconazole.

Two hundred seventy-five samples from 73 patients were included in the analysis. Overall, 60% of the posaconazole and 55% of the itraconazole concentrations were subtherapeutic. Administration of posaconazole suspension resulted significantly (P<.01) more often in subtherapeutic concentrations than tablets (68% vs 10%). Patients treated with posaconazole showed less positive fungal records resulting in a transition from prophylaxis to therapy than patients treated with itraconazole (10% vs 33%, P-value .029). The detection of a fungal pathogen was not associated with the measured plasma concentrations or the achievement of the target concentrations.

Our findings suggest that posaconazole should be used instead of itraconazole for systemic prophylaxis in critically ill lung transplant recipients.

The aim of this study was to describe the dynamic changes in blood work following individual adjusted dosage of intravenously administered iron(III) isomaltoside in a 4-week period prior to surgery in patients with colorectal cancer.

This was a single-centre, observational cohort study with prospectively collected data, including patients with colorectal cancer receiving preoperative treatment with iron(III) isomaltoside. Blood samples were taken at baseline, 1 week, 2 weeks and 4 weeks after initial treatment. Sixty-two patients were included in the study.

Sixty-two patients were included for final analysis. The mean increase in haemoglobin was 0.77g/dl (95% CI 0.52-1.03 g/dl, P<0.0001) at week 1, 1.5g/dl (95% CI 1.21-1.80 g/dl, P<0.0001) at week 2 and 2.13g/dl (95% CI 1.71-2.55 g/dl, P<0.0001) at week 4. Patients with severe anaemia (<9.02g/dl) showed the largest increase in haemoglobin during the treatment course (2.92g/dl, 95% CI 2.27-3.58g/dl, P<0.0001). Patients with mild anaemia (>10.31g/dl) did not show a significant increase (0.66g/dl, 95% CI -0.29-1.61 g/dl, P=0.17). The mean of transferrin saturation after 4 weeks was 8% (95% CI 6%-10%, P<0.0001).

After intravenously administered iron, patients with severe anaemia had the most substantial increase in haemoglobin, and the increase was largest after 4 weeks. PFI-3 molecular weight Patients with mild anaemia did not have an increase in haemoglobin during the treatment course. link2 The vast majority of patients still had iron deficiency at surgery 4 weeks after the initial treatment.

The neuro-oncology community in Australia is well positioned to collaborate internationally, with a motivated trials group, strong regulatory bodies and an attractive fiscal environment. We sought to identify gaps in the Australian neuro-oncology clinical trials landscape and describe strategies to increase international trial access in Australia.

We searched clinical trial registries to identify active adult primary brain cancer trials. We compared the participation rate and phase of these trials between tumour types and countries. A survey was distributed to the Cooperative Trials Group for Neuro-Oncology membership to identify barriers and solutions to effective international collaboration.

Globally, 307 trials for adult primary brain cancers were identified. These included 50% pharmaceutical agents, 18% cellular therapies and 9% radiation therapy. Twelve adult primary brain cancer trials were actively recruiting in Australia at the time the survey was sent out. There were more early phase brain canc mutual ethics schemes.Stigmatization of patients exists in nursing and results in less than optimal nursing care and poor patient outcomes. It is also a violation of our code of ethics. In order to eliminate stigmatization from nursing practice, it is necessary to understand how it develops. Two possible theoretical pathways are proposed to explain the development of stigmatization in nursing. These pathways are informed by a conceptual understanding of stigma and theories of professional socialization, professional formation, symbolic interactionism, and social cognitive theory. Re-labeling and role-taking and moral disengagement are proposed as two possible processes that may lead to stigmatization of patients. Both proposed pathways have implications on professional socialization, formation, and the development of professional identity. Devoting attention to and reframing normative behavioral expectations, eliminating labeling, developing empathy, focusing on relationships, and cultivating ethical comportment and moral maturity during nursing formation may reduce the stigmatization of patients by nurses.Spatial organization and gene expression of mammalian chromosomes are maintained and regulated in conjunction with cell cycle progression. This is perturbed once cells enter senescence and the highly abundant HMGB1 protein is depleted from nuclei to act as an extracellular proinflammatory stimulus. Despite its physiological importance, we know little about the positioning of HMGB1 on chromatin and its nuclear roles. To address this, we mapped HMGB1 binding genome-wide in two primary cell lines. We integrated ChIP-seq and Hi-C with graph theory to uncover clustering of HMGB1-marked topological domains that harbor genes involved in paracrine senescence. Using simplified Cross-Linking and Immuno-Precipitation and functional tests, we show that HMGB1 is also a bona fide RNA-binding protein (RBP) binding hundreds of mRNAs. It presents an interactome rich in RBPs implicated in senescence regulation. The mRNAs of many of these RBPs are directly bound by HMGB1 and regulate availability of SASP-relevant transcripts. Our findings reveal a broader than hitherto assumed role for HMGB1 in coordinating chromatin folding and RNA homeostasis as part of a regulatory loop controlling cell-autonomous and paracrine senescence.

Subsequent cancers (SCs) after melanoma diagnosis further increases the risks of mortality and medical costs. This population-based analysis aimed to evaluate risk factors for SC, mortality, and medical costs of melanoma patients with SC.

A retrospective cohort analysis was conducted using a nationwide claims database during 2002-2017 in South Korea. SC was defined as having other types of cancer diagnoses other than subsequent melanoma during-up to 5 years after melanoma diagnosis. Melanoma patients were divided into patients with and without SC, and the overall and subgroup survival rates, the risk of developing SC, and the total medical costs were analyzed using a Kaplan-Meier method and regressions.

A total of 3740 melanoma patients were included in the analysis (mean age, 62.3±15.4 y; 47.2% men), and 2273 patients (1157 within 2 months, 756 after 2 months of melanoma diagnosis) had SC. Higher Charlson comorbidity index score and male sex significantly increased the risk of developing SC. Five-year survival rate and cumulative medical costs were 62.3% (95% confidence interval [CI], 60.8-63.9) and $21,413, respectively, in all patients. Patients with SC diagnosed after 2 months showed the lowest survival rate of 47.8% (95% CI, 44.3-51.4) and the highest costs of $27,081, showing a mortality hazard ratio of 1.65 (range, 1.46-1.86) and a cost ratio of 1.189 (range, 1.112-1.271) compared with those without SC.

This study presented survival outcomes and medical costs in melanoma patients and confirmed that SC after the first diagnosis of melanoma significantly increased disease burden in terms of mortality and medical costs.

Hence, we aimed to investigate the effect of sorafenib between HBV-HCC and HCV-HCC patients in Taiwan. From August 2012 to December 2016, 575 consecutive advanced HCC patients received sorafenib under the reimbursement of Taiwan national health insurance in our hospital. Radiologic assessment was performed at a 2-month interval. Those patients with tumor progression or liver function deterioration were disallowed for further sorafenib use. Patients with HBV or HCV infection were, retrospectively, enrolled and followed till December 2018. There were 277 (62.4%) HBV-HCC patients and 167 (37.6%) HCV-HCC patients. Before sorafenib, 192 (69.3%) HBV-HCC patients who had used nucleoside analogs (NAs) for HBV management, whereas only 5 (3%) HCV-HCC patients received interferon-based antiviral therapy.
