Abstract
Background: Methadone is well known for its long duration of action and propensity for mortality after an overdose. The present research was aimed at evaluating the clinical manifestations and time trends of methadone exposure patients in US hospitals. Methods: We queried the American College of Medical Toxicology’s ToxIC Case Registry for all cases of methadone exposure prospectively recorded between January 1, 2010, and December 31, 2017. The collected information included demographic features, clinical presentations, therapeutic interventions, poisoning type (acute, chronic or acute-on-chronic), and the reason(s) for exposure. Descriptive data and relative frequencies were used to investigate the participants’ characteristics. Our data analysis was performed using SPSS version 19 and Prism software. The trends and clinical manifestations of methadone poisoning over the time period of the study was specifically investigated. Results: Nine hundred and seventy-three patients who met our inclusion criteria with a mean age of 41.9 ± 16.6 years (range: 11 months-78 years) were analyzed. Five hundred eighty-two (60.2%) were male. The highest rate of methadone poisoning was observed in 2013. There was an increasing rate of methadone exposures in 2010–2013, followed by a decline in 2014–2017. The most common clinical manifestations in methadone poisoned patients were coma (48.6%) and respiratory depression (33.6%). The in-hospital mortality rate of methadone poisoning was 1.4%. Conclusion: Inpatient methadone exposures enhanced significantly from 2010 to 2013, after which a significant reduction occurred in the years 2014 to 2017.

Abstract
Background:Vitamin D plays an important role in bone health and other diseases, however, there is no consensus over the optimal serum 25-hydroxyvitamin D (25(OH)D) concentration. Many studies consider that the 25(OH)D concerntration which maximally inhibit serum intact parathyroid hormone (iPTH) might be the optimal status for vitamin D sufficiency. This study was performed to study the relationship between 25(OH)D concentration and intact parathyroid hormone (iPTH) concentration in the Chinese non-clinical population aged 18-44y. Methods: The serum samples of adults aged 18-44 years old were selected from the established serum bank of Chinese Chronic Diseases and Nutrition Survey (CCDNS, 2015-2018). The serum 25(OH)D concentration was determined by high performance liquid chromatography tandem mass spectrometer, and the iPTH was determined by electronic chemiluminescence method. The relationship of 25(OH)D and iPTH were analyzed by correlation analysis, segmented linear regression and the confidence interval was determined by bootstrap method. Results: 623 serum samples (293 male, 330 female) of 25(OH)D concentration and iPTH concentration were analyzed. Significant higher 25(OH)D concentration was found in male than female. And the samples from the southern China had higher 25(OH)D concentration than those from the northern China. Samples from autumn had higher 25(OH)D concentration than those from spring and winter. The inversely relationship between 25(OH)D concentration and iPTH concentration was observed in both male and female. The concentration of 25(OH)D was 19.2 (10.1-27.2) ng/mL (P=0.02) when iPTH entered the plateau in women and no plateau for iPTH was found in men. Conclusions: The relationship between 25(OH)D and iPTH differs by sex among Chinese adults aged 18-44y. Further study is needed to evaluate the sex-specific ranges of optimal vitamin D. Trial registration: Not applicable. Keywords: 25-hydroxyvitamin D; parathyroid hormone; plateau; Chinese adults

Abstract
Emergency Department (ED) crowding occurs when demand for care exceeds the available resources. Crowding has been associated with decreased quality of care and increased mortality, but the prevalence on a national level is unknown in most countries. We performed a national, cross-sectional study on staffing levels, staff workload, occupancy rate and patients waiting for an in-hospital bed (boarding) at five timepoints during 24 hours in Swedish EDs. Complete data were collected from 37 (51% of all) EDs in Sweden. High occupancy rate indicated crowding at twelve hospitals (37.5 %) at 31 out of 170 (18.2%) timepoints. Mean workload (measured on a scale from 1, no workload to 6, very high workload) was moderate at 2.65 (±1.25). Boarding was more prevalent in academic EDs than rural EDs (median 3 vs 0). There were an average of 2.6, 4.6 and 3.2 patients per registered nurse, enrolled nurse and physician, respectively. ED crowding based on occupancy rate was prevalent on a national level in Sweden and comparable with international data. Staff workload, boarding and patient to staff ratios were generally lower than previously described.

Abstract
BackgroundBRAF-activated non-coding RNA (BANCR) was reported to be aberrantly expressed in various tumor tissues and has been confirmed to function as tumor suppressor or oncogene in many types of cancers. Considering the conflicting results and insufficient sampling, a meta-analysis was performed to explore the prognostic value of BANCR in various carcinomas.MethodsA comprehensive literature search of PubMed, Web of Science, EMBASE, Cochrane Library and the China National Knowledge Infrastructure (CNKI) was conducted to collected relevant articles.ResultsPooling results showed strong relevance of high BANCR expression and poor overall survival (OS) (HR=1.60, 95% confidence interval (CI): 1.19-2.15, P =0.002) and recurrence-free survival (RFS) (HR=1.53, 95%CI: 1.27-1.85, P <0.00001). In addition, high BANCR expression predicts advanced tumor stage (OR=2.39, 95%CI: 1.26-4.53, P =0.008), present lymph node metastasis (OR=2.03, 95%CI: 1.08-3.83, P =0.03), positive distant metastasis (OR=3.08, 95%CI: 1.92-4.96, P <0.00001) and bigger tumor size (OR: 1.63, 95%CI: 1.09-2.46, P =0.02).ConclusionsThe results showed that elevated BANCR expression was associated with unfavorable prognosis for most of cancer patients, and BANCR could be served as a promising therapeutic target and independent prognostic predictor for cancers.

Abstract
Background: It may be impossible to perform cancer surgery with free margins in the presence of an unresectable structure. Local drug treatment after surgery has been proposed to increase the rate of tumor control. Methods: Multi-nanolayers (10-330nm) were generated by a low-pressure (375mTorr) inductively coupled plasma (13.56MHz) reactor for anticancer drug delivery by the deposition of polycaprolactone-polyethylene glycol multistack barrier on the collagen membrane (100µm thickness). Carboplatin (300µg/cm 2 ) was used for the in vitro and in vivo investigations. Energy-dispersive X-ray spectroscopy (15keV), scanning electron microscopy and inductively coupled plasma mass spectrometry were used to detect the presence of carboplatin in the nanolayer, the tumor sample and the culture medium. Preclinical studies were performed on ovarian (OVCAR-3NIH) and colon (CT26) cancer cell lines as xenografts (45 days) and allografts (23 days) in Swiss-nude (n=6) and immunocompetent BALB/cByJ mice (n=24), respectively. Results: The loading of carboplatin or other drugs between the nanofilm on the collagen membrane did not modify the mesh complex architecture or the drug properties. Drugs were detectable on the membrane for more than two weeks in the in vitro analysis and more than 10 days in the in vivo analysis. Cytotoxic mesh decreased cell adherence (down 5.42-fold) and induced cancer cell destruction (up to 7.87-fold). Implantation of the mesh on the mouse tumor nodule modified the cell architecture and decreased the tumor size (50.26%) compared to the control by inducing cell apoptosis. Conclusion: Plasma technology allows a mesh to be built with multi-nanolayer anticancer drug delivery on collagen membranes.

Abstract
Background: Metastatic prostate cancer (PC) is highly lethal. The ability to identify primary tumors capable of dissemination is an unmet need in the quest to understand lethal biology and improve patient outcomes. Previous studies have linked chromosomal instability (CIN), which generates aneuploidy following chromosomal missegregation during mitosis, to PC progression. Evidence of CIN includes broad copy number alterations (CNAs) spanning >300 base pairs of DNA, which may also be measured via RNA expression signatures associated with CNA frequency. Signatures of CIN in metastatic PC, however, have not been interrogated or well defined. We examined a published 70-gene CIN signature (CIN70) in untreated and castration-resistant prostate cancer (CRPC) cohorts from The Cancer Genome Atlas (TCGA) and previously published reports. We also performed transcriptome and CNA analysis in a unique cohort of untreated primary tumors collected from diagnostic prostate needle biopsies (PNBX) of localized (M0) and metastatic (M1) cases to determine if CIN was linked to clinical stage and outcome.
Methods: PNBX were collected from 99 patients treated in the VA Greater Los Angeles (GLA-VA) Healthcare System between 2000-2016. Total RNA was extracted from high-grade cancer areas in PNBX cores, followed by RNA sequencing and/or copy number analysis using OncoScan. Multivariate logistic regression analyses permitted calculation of odds ratios for CIN status (high versus low) in an expanded GLA-VA PNBX cohort (n = 121).
Results: The CIN70 signature was significantly enriched in primary tumors and CRPC metastases from M1 PC cases. An intersection of gene signatures comprised of differentially expressed genes (DEGs) generated through comparison of M1 versus M0 PNBX and primary CRPC tumors versus metastases revealed a 157-gene "metastasis" signature that was further distilled to 7-genes (PC-CIN) regulating centrosomes, chromosomal segregation, and mitotic spindle assembly. High PC-CIN scores correlated with CRPC, PC-death and all-cause mortality in the expanded GLA-VA PNBX cohort. Interestingly, approximately 1/3 of M1 PNBX cases exhibited low CIN, illuminating differential pathways of lethal PC progression.
Conclusions: Measuring CIN in PNBX by transcriptome profiling is feasible, and the PC-CIN signature may identify patients with a high risk of lethal progression at the time of diagnosis.

Abstract
Aldehyde dehydrogenase 1A3 (ALDH1A3) has been implicated in the survival and proliferation of prostate cancer cells. We retrospectively reviewed our patients with advanced disease on adjuvant hormonal therapy after prostatectomy. Time to castration resistance stage was documented. And Immunohistochemistry analysis for ALDH1A3 was performed for those patient samples on tissue microarray. Using bioinformatics analysis for RNA sequencing data of both primary prostate cancer and metastatic castration resistance prostate cancer (mCRPC) from online datasets, we have found that the expression level of ALDH1A3 is lower in mCRPC group than in primary cancer group. Crispr-Cas9 was used to knock out ALDH1A3 in prostate cancer luminal cells, and morphologic analysis as well as the Gene Set Enrichment Analysis (GSEA) were facilitated to discover the mechanisms of the resistance phenotype. We found that the patients with ALDH1A3 low expression had shorter time to progression to castration resistance compared with those of higher expression group on adjuvant hormonal therapy after radical prostatectomy. The ALDH1A3 knockout cells gradually acquired resistance to androgen deprivation therapy, few cells have been found in knockout group showing as that the spindle-like luminal cells in charcoal stripped medium. Furthermore, PI3K pathway activation has been confirmed by Western blot. The PI3K pathway inhibitor BEZ235 has been demonstrated that the acquired ADT resistance by ALDH1A3 down regulation could be rescued by PI3K pathway inhibitor. Together, these results suggested a novel function for ALDH1A3 in development of mCRPC, and indicated PI3K pathway inhibitor has the potential in the treatment of a subgroup of mCRPC patients.

Abstract
Background The “hot cross bun” (HCB) sign, a cruciform hyperintensity in the pons on magnetic resonance imaging (MRI), has gradually been identified as a typical finding in multiple system atrophy, cerebellar-type (MSA-C). Few reports have evaluated the sensitivity of an HCB including a cruciform hyperintensity and vertical line in the pons, which precedes a cruciform hyperintensity, in the early stages of MSA-C. Moreover, the difference in frequency and timing of appearance of an HCB between MSA-C and spinocerebellar ataxia type 3 (SCA3) has not been fully investigated. Methods This study investigated the time at which an HCB and orthostatic hypotension (OH) appeared in 41 patients with MSA-C, based on brain MRI and head-up tilt test. The MRI findings were compared with those of 26 patients with SCA3. The pontine signal findings on T2-weighted MRI were graded as 0 (no change), 1 (a vertical T2 high-intensity line), or 2 (a cruciform T2 high-intensity line), with grades 1 or 2 considered as an HCB. OH 30/15 was defined as a decrease in systolic blood pressure of > 30 mmHg or diastolic blood pressure of > 15 mmHg. Results Among the 24 patients with MSA-C within 2 years from the onset of motor symptoms, an HCB was detected in 91.7%, whereas OH 30/15 was present in 60.0%. Among the 36 patients with MSA-C within 3 years from the onset of motor symptoms, a grade 2 HCB was detected in 66.7% of those with MSA-C but in none of those with SCA-3. Conclusions HCB is a highly sensitive finding for MSA-C, even in the early stages of the disease. A grade 2 HCB in the early stage is an extremely specific finding for differentiating MSA-C from SCA-3.

Abstract
In order to avoid the influence of associated bacteria on the target cyanobacteria for physiological and molecular studies, a traditional and reliable method based on solid-liquid alternate cultivation is carried out to purify the non-axenic cyanobacterium Microcystis aeruginosa FACHB-905. On the basis of 16S rDNA gene sequences, two associated bacteria named strain B905-1 and strain B905-2, are identified as Pannonibacter sp. and Chryseobacterium sp. with a 99% and 97% similarity value, respectively. To better investigate the general interaction between the bacterium and the cyanobacterium, the effect of strain B905-1 on the axenic cyanobacterium M. aeruginosa FACHB-905A is studied. Results indicate that the axenic M. aeruginosa FACHB-905A could not form colonies on BG11 agar medium without the addition of strain B905-1, while it grows well in BG11 liquid medium. Although the presence of B905-1 was not indispensable for the growth of M. aeruginosa FACHB-905A, B905-1 had a positive effect on promoting the growth of M. aeruginosa FACHB-905A. The purification technique for cyanobacteria described in this study is potentially applicable to a wider range of filamentous cyanobacteria.

Abstract
Background Autotrophic prokaryotes are crucial participants in the global carbon cycle, and autotrophic carbon fixation contributes approximately 50% of the global net primary production in aquatic ecosystems per year. Salinity is a prominent regulator structuring microbial communities in diverse aquatic ecosystems. However, little information is available regarding the compositional and physiological response of autotrophic microbial communities to salinity change. Here, we used genome-resolved metagenomics to study autotrophic microbial communities in 25 Tibetan lacustrine sediments with a salinity gradient (from 0.54‰ to 82.6‰). Results117 metagenome-assembled genomes (MAGs) with carbon fixation potential belonging to 12 phyla were retrieved, of which approximately 21% were not affiliated with the known orders, suggesting taxonomically diverse autotrophic assemblages in sediments. The total abundance of these putative autotrophs decreased significantly with increasing salinity, and the variation of sediment autotrophic communities was mainly driven by salinity, pH and TOC. Notably, a change in the predominant lineage from Betaproteobacteria to Deltaproteobacteria was observed along the salinity gradient, and the dominant pathway for carbon fixation shifted from the Calvin-Benson-Bassham (CBB) cycle to more energy efficient Wood-Lungdahl (WL) pathway with glycolysis from Entner-Doudoroff to more exergonic Embden-Meyerhof-Parnas, demonstrating that the physiological efficiency increases from freshwater to hypersaline autotrophic communities. Metabolic inference revealed major links for carbon fixation to the oxidation of reduced sulfur compounds, ferrous iron and carbon monoxide, denitrification and nitrogen fixation in these MAGs, as well as the occurrence of dissimilatory sulfate reduction and the WL pathway dominating hypersaline sediments, greatly extending the understanding of metabolic versatility and diverse ecological niches of autotrophic microorganisms. Conclusions This study provided a systematic attempt to characterize the response of carbon fixation pathways to salinity and the knowledge essential for revealing ecological roles of autotrophic prokaryotes in aquatic habitats. These findings suggest with increased salinity, physiological efficiency of the autotrophic community increases, which has important implications for understanding the carbon budget in aquatic ecosystems.

Abstract
Background Revealing the specificity and flexibility of the algal symbiont-host association is fundamental for understanding how species can occupy a diverse range of habitats. Here we assessed the global distribution of the algal symbiont diversity for three shallow-water species of large benthic foraminifera (LBF) of the genus Amphistegina . Specifically, weinvestigated the role of habitat and host identity on the diversity of algal biome. Results Here we used next-generation sequencing to identify the algal biome in the species A. lobifera , A. lessonii , and A. radiata , collected from shallow habitats in 16 sites, spanning from the Mediterranean Sea to French Polynesia. Results showed the consistent presence of Fragilariales as the main algal taxa associated with all species across sites analysed. However, we uncovered unprecedented diversity of algal phylotypes found in low abundance.We further found high variability in algal biomes both within and between species and sites, indicating a substantial level of flexibility in symbiont associations. The effect of site was significant in all species analysed, and showed that local habitat is the main factor influencing the identity of algal symbionts. Symbiotic associations are also not constrained by the species identity nor the phylogenetic relationship among closely related hosts, suggesting symbiont identity plays a limited role in the evolutionary history of the genus Amphistegina . Conclusions We found that species of Amphistegina form flexible symbiotic relationship with algal taxa, which are primarily shaped by their local habitat. These observations strongly suggest that the capacity of Amphistegina species to utilise a diverse array of available symbionts likely underpins the ecological success of these crucial calcifying organisms across their extensive geographic range.
