Abstract
BACKGROUND The androgen/androgen receptor (AR)-signaling axis plays a central role in prostate cancer (PCa). Upon androgen-binding the AR dimerizes with another AR, and translocates into the nucleus where the AR-dimer activates/inactivates androgen-dependent genes. Consequently, treatments for PCa are commonly based on androgen deprivation therapy (ADT). The clinical benefits of ADT are only transitory and most tumors develop mechanisms allowing the AR to bypass its need for physiological levels of circulating androgens. Clinical failure of ADT is often characterized by the synthesis of a constitutively active AR splice variant, termed AR-V7. AR-V7 mRNA expression is considered as a resistance mechanism following ADT. AR-V7 no longer needs androgenic stimuli for nuclear entry and/or dimerization. METHODS Our goal was to mechanistically decipher the interaction between full-length AR (AR-FL) and AR-V7 in AR-null HEK-293 cells using the NanoLuc Binary Technology under androgen stimulation and deprivation conditions. RESULTS Our data point toward a hypothesis that AR-FL/AR-FL homodimers form in the cytoplasm, whereas AR-V7/AR-V7 homodimers localize in the nucleus. However, after androgen stimulation, all the AR-FL/AR-FL, AR-FL/AR-V7 and AR-V7/AR-V7 dimers were localized in the nucleus. CONCLUSIONS We showed that AR-FL and AR-V7 form heterodimers that localize to the nucleus, whereas AR-V7/AR-V7 dimers were found to localize in the absence of androgens in the nucleus.

Abstract
Covering: September 1964 to June 2023Bacteria and fungi living in symbiosis with insects have been studied over the last sixty years and found to be important sources of bioactive natural products. Not only classic producers of secondary metabolites such as Streptomyces and other members of the phylum Actinobacteria but also numerous bacteria from the phyla Proteobacteria and Firmicutes and an impressive array of fungi (usually pathogenic) serve as the source of a structurally diverse number of small molecules with important biological activities including antimicrobial, cytotoxic, antiparasitic and specific enzyme inhibitors. The insect niche is often the exclusive provider of microbes producing unique types of biologically active compounds such as gerumycins, pederin, dinactin, and formicamycins. However, numerous insects still have not been described taxonomically, and in most cases, the study of their microbiota is completely unexplored. In this review, we present a comprehensive survey of 553 natural products produced by microorganisms isolated from insects by collating and classifying all the data according to the type of compound (rather than the insect or microbial source). The analysis of the correlations among the metadata related to insects, microbial partners, and their produced compounds provides valuable insights into the intricate dynamics between insects and their symbionts as well as the impact of their metabolites on these relationships. Herein, we focus on the chemical structure, biosynthesis, and biological activities of the most relevant compounds.

Abstract
BACKGROUND Primary Graft Dysfunction (PGD) is the leading cause of morbidity and mortality early after heart transplant (HT). The International Consortium on PGD is a multicenter collaboration dedicated to identifying the clinical risk factors for PGD in the contemporary era of HT. The objectives of the current report were to 1) assess the incidence of severe PGD in an international cohort, 2) evaluate the performance of the most validated PGD risk tool, the RADIAL score, in a contemporary cohort, and 3) redefine clinical risk factors for severe PGD in the current era of HT. METHODS This is a retrospective, observational study of consecutive adult HT recipients between 2010 and 2020 in 10 centers in the United States, Canada, and Europe. Patients with severe PGD were compared to those without severe PGD (comprising those with no, mild and moderate PGD). The RADIAL score was calculated for each transplant recipient. The discriminatory power of the RADIAL score was evaluated using receiver operating characteristic (ROC) analysis and its calibration was assessed by plotting the percentage of PGD predicted versus observed. To identify clinical risk factors associated with severe PGD, we performed multivariable mixed-effects logistic regression modeling to account for among-center variability. RESULTS A total of 2,746 patients have been enrolled in the registry to date, including 2,015 (73.4%) from North America, and 731 (26.6%) from Europe. 215 participants (7.8%) met the criteria for severe PGD. There was an increase in the incidence of severe PGD over the study period (p-value for trend by difference sign test = 0.004). The Kaplan Meier estimate for 1-year survival was 75.7% [95%CI 69.4-80.9%] in patients with severe PGD as compared to 94.4% [95% CI 93.5-95.2%] in those without severe PGD (log-rank p-value <0.001). The RADIAL score performed poorly in our contemporary cohort and was not associated with severe PGD with an AUC of 0.53 (95%CI 0.48-0.58). In the multivariable regression model, acute preoperative dialysis (OR 2.41, 95% CI 1.31 - 4.43), durable LVAD support (OR 1.77, 95% CI 1.13 - 2.77), and total ischemic time (OR 1.20 for each additional hour, 95% CI 1.02 - 1.41) were associated with an increased risk of severe PGD. CONCLUSIONS Our consortium has identified an increasing incidence of PGD in the modern transplant era. We identified contemporary risk factors for this early post-transplant complication, which confers a high mortality risk. These results may enable the identification of patients at high risk for developing severe PGD in order to inform peri-transplant donor and recipient management practices.

Abstract
Dormant bacterial cells do not divide and are not immediately culturable, but they persist in a state of low metabolic activity, a physiological state having clinical relevance, for instance in latent tuberculosis. Resuscitation-promoting factors (Rpfs) are proteins that act as signalling molecules mediating growth and replication. In this study we aimed to test the effect of Rpfs from Micrococcus luteus on the number and diversity of cultured bacteria using insect and soil samples, and to examine if the increase in culturability could be reproduced with the putative reaction product of Rpf, 1,6-anhydro-N-acetylmuramic acid (1,6-anhydro-MurNAc). The rpf gene from Micrococcus luteus was amplified and cloned into a pET21b expression vector and the protein was expressed in Escherichia coli BL21(DE3) cells and purified by affinity chromatography using a hexa-histidine tag. 1,6-Anhydro-MurNAc was prepared using reported chemical synthesis methods. Recombinant Rpf protein or 1,6-anhydro-MurNAc were added to R2A cultivation media, and their effect on the culturability of bacteria from eight environmental samples including four cockroach guts and four soils was examined. Colony-forming units, 16S rRNA gene copies and Illumina amplicon sequencing of the 16S rRNA gene were measured for all eight samples subjected to three different treatments: Rpf, 1,6-anhydro-MurNAc or blank control. Both Rpf and 1,6-anhydro-MurNAc increased the number of colony-forming units and of 16S rRNA gene copies across the samples although the protein was more effective. The Rpf and 1,6-anhydro-MurNAc promoted the cultivation of a diverse set of bacteria and in particular certain clades of the phyla Actinomycetota and Bacillota . This study opens the path for improved cultivation strategies aiming to isolate and study yet undescribed living bacterial organisms.

Abstract
The genus Vagococcus belongs to the family Enterococcaceae (order Lactobacillales) and is closely related to the genus Enterococcus. Currently, 19 species of the genus have been validly named. In this study, we isolated strain G314FT from the common green bottle fly Lucilia sericata collected in Germany. Sequencing of its almost-complete 16S rRNA gene revealed that the isolate belongs to the genus Vagococcus, being closely related to Vagococcus bubulae SS1994T with high sequence identity (99.50 %), followed by Vagococcus martis D7T301T (98.86 %), Vagococcus vulneris SS1995T (98.71 %), Vagococcus teuberi DSM 21459T (98.64 %), Vagococcus silagei 2B-2T (98.64 %) and Vagococcus penaei CD276T (98.64 %). Genome sequencing of strain G314FT was performed by a combination of Illumina and Oxford Nanopore technology, yielding a circular genome with a size of 2 139 468 bp and an 11 kb plasmid. Average nucleotide identity and digital DNA-DNA hybridization values were calculated between G314FT and its closest-related taxa, and found to be <91 % and <40 %, respectively, thus strongly supporting that strain G314FT represents a novel species of the genus Vagococcus. Phylogenetic and core protein-based phylogenomic trees revealed that G314FT was closely related to a group of three species, V. bubulae SS1994T, V. martis D7T301T and V. teuberi DSM 21459T. Comparatively, the genome of G314FT is the smallest in the group of the four related species, and the biochemical pathway comparison using BlastKOALA revealed that G314FT has lost some amino acid biosynthetic proteins; however, it has gained enzymes for carbohydrate metabolism. Phenotypically, G314FT was consistent with other species of the genus Vagococcus including a negative catalase reaction and non-motility. Using the polyphasic approach, our data supports that the isolate represents a new species, for which we propose the name Vagococcus luciliae G314FT (=DSM 112651T= CCM 9164T).

Abstract
Acetic acid bacteria (family Acetobacteraceae) are found in the gut of most insects. Two clades are currently recognized: Commensalibacter-Entomobacter and Bombella-Oecophyllibacter. The latter group is only found in hymenopteran insects and the described species have been isolated from bees and ants. In this study, two new strains DDB2-T1T (=KACC 21507T=LMG 31759T) and DM15PD (=CCM 9165=DSM 112731=KACC 22353=LMG 32454) were isolated from wasps collected in the Republic of Korea and Germany, respectively. Molecular and phenotypic analysis revealed that the strains are closely related, with 16S rRNA gene sequences showing 100 % identity and genomic average nucleotide identity (ANI) values ≥99 %. The closest related species based on type strain 16S rRNA gene sequences are Swingsia samuiensis, Acetobacter peroxydans, Bombella favorum and Bombella intestini (94.8-94.7% identity), whereas the closest related species based on type strain genome analysis are Saccharibacter floricola and Bombella intestini (ANI values of 68.8 and 68.2 %, respectively). The reconstruction of a phylogenomic tree based on 107 core proteins revealed that the branch leading to DDB2-T1T and DM15PD is localized between Oecophyllibacter and Saccharibacter-Bombella. Further genomic distance metrics such as ANI, percentage of conserved proteins and alignment fraction values were consistent with these strains belonging to a new genus. The key phenotypic characteristics were one MALDI-TOF-MS peak (m/z=4601.9±2.0) and the ability to produce acid from d-arabinose. Based on this polyphasic approach, including phylogenetics, phylogenomics, genome distance calculations, ecology and phenotypic characteristics, we propose to name the novel strains Aristophania vespae gen. nov., sp. nov., with the type strain DDB2-T1T (=KACC 21507T=LMG 31759T).

Abstract
In the present study, we further analyzed the data obtained in our previous study, where we investigated the cell-free DNA (cfDNA) of 34 progressive prostate cancer patients via targeted sequencing. Here, we studied the occurrence and prognostic impact of sequence variants according to their clinical pathological significance (CPS) or their functional impact (FI) in 23 DNA damage repair (DDR) genes with a focus on the ATM serine/threonine kinase gene (ATM). All patients had at least one DDR gene with a CPS or FI variant. Kaplan-Meier analysis indicated that the group with a higher number of CPS variants in DDR genes had a shorter time to treatment change (TTC) compared to the group with a lower number of CPS variants (p = 0.038). Analysis of each DDR gene revealed that CPS variants in the ATM gene and FI variants in the nibrin (NBN) gene showed a shorter TTC (p = 0.034 and p = 0.042). In addition, patients with CPS variants in the ATM gene had shorter overall survival (OS; p = 0.022) and disease-specific survival (DSS; p = 0.010) than patients without these variants. Interestingly, patients with CPS variants in seven DDR genes possessed a better OS (p = 0.008) and DSS (p = 0.009), and patients with FI variants in four DDR genes showed a better OS (p = 0.007) and DSS (p = 0.008). Together, these findings demonstrated that the analysis of cfDNA for gene variants in DDR genes provides prognostic information that may be helpful for future temporal and targeted treatment decisions for advanced PCa patients.

Abstract
A new series of sulfonamides, 8a-b, 10, 12, and 14a-b, were synthesized by N-sulfonation reaction with sulfonyl chlorides 6a-b. Five new series of chalcone-sulfonamide hybrids (16-20)a-f were prepared via Claisen–Schmidt condensation of the newly obtained sulfonamides with aromatic aldehydes 15a-f in basic medium. Chalcones substituted with chlorine at position 4 of each series were used as precursors for the generation of their five-membered heterocyclic pyrazoline (22-23)a-d, (24-25)a-b and carbothioamide 27a-f derivatives. The synthesized compounds were evaluated for their anticancer and antituberculosis activities. To determine their anticancer activity, compounds were screened against sixty human cancer cell lines at a single dose (10 μM). Compounds 17a-c were highly active against LOX IMVI (melanoma), with IC50 values of 0.34, 0.73 and 0.54 μM, respectively. Chalcone 18e showed remarkable results against the entire panel of leukemia cell lines with IC50 values between 0.99–2.52 μM. Moreover, compounds 20e and 20f displayed growth inhibition of Mycobacterium tuberculosis H37Rv at concentrations below 10 μM. Although they showed low selectivity in cytotoxicity tests against the Vero cell line, further optimization could advance the potential biological activity of the selected compounds.

Abstract
Kim et al. isolated a polystyrene-degrading bacterium from the gut of the superworm (Zophobas atratus) and identified it as Pseudomonas aeruginosa DSM 50071. However, the original P. aeruginosa DSM 50071 was isolated before 1946 from an unknown source by researchers from Merck Sharp & Dohme. To claim that the superworm bacterial isolate is the same P. aeruginosa DSM 50071 strain is misleading. The two strains are different, and the original DSM 50071 strain may or may not degrade polystyrene. The recommendation to Kim et al. is to label the strain isolated from the superworm with a unique code, to re-sequence its 16S rRNA gene to near completeness, and to deposit the culture in a public collection so that other researchers and society may benefit from its study.

Abstract
A Gram-negative bacterial strain, G163CMT, was isolated from the gut of the Asian emerald cockroach Corydidarum magnifica. The 16S rRNA gene sequence (1416 bp) of strain G163CMT showed 99.22% similarity to
Pseudocitrobacter faecalis
CCM 8479T and
Pseudocitrobacter vendiensis
CPO20170097T. The average nucleotide identity, digital DNA–DNA hybridization and average amino acid identity values of strain G163CMT were 92.4, 48.8 and 95.7% to
P. faecalis
CCM 8479T, and 93.3, 52.4 and 95.7% to
P. vendiensis
CPO20170097T. This strongly supports the designation of G163CMT as representing a new species in the genus
Pseudocitrobacter
. Phylogenetic trees based on the alignment of 16S rRNA, multilocus sequence analysis of six single-copy genes (fusA, pyrG, leuS, rpoB, recN and mnmE) and 107 core protein sequences consistently showed G163CMT to be a member of the genus
Pseudocitrobacter
, closely related to
P. vendiensis
CPO20170097T. In contrast to
P. faecalis
CCM 8479T and
P. vendiensis
CPO20170097T, the genome of G163CMT did not encode for proteins conferring resistance to antibiotics. However, all three genomes encoded a similar number of virulence factors and specialized metabolite biosynthetic proteins. The major fatty acids of strain G163CMT were C16:0 (31.5 %), C18:1 ω7c (22.6 %), C17:0 cyclo (15.3 %) and C14:0 (6.5 %). Based on the polyphasic results, we conclude that strain G163CMT represents a novel species of the genus
Pseudocitrobacter
and we propose the name Pseudocitrobacter corydidari sp. nov. with the type strain G163CMT (=DSM 112648T=CCM 9160T).

Abstract
A Gram-stain-positive bacterial strain, designated G127ATT, was isolated as soft small white colonies from the hindgut of the cockroach Archimandrita tesselata. Examination of the complete 16S rRNA sequence mapped the strain to the genus
Agromyces
. The type strain with the highest pairwise similarity was
Agromyces marinus
H23-8T (97.3%). The genome of G127ATT was sequenced by a combination of Illumina and Nanopore methods and consisted of a single circular DNA molecule with a size of 3.45 Mb. The DNA G+C content was 71.3 mol%. A phylogenomic tree based on conserved single copy housekeeping genes, placed G127ATT among the ancestral species of the genus
Agromyces
, and only
Agromyces atrinae
P27T was found to diverge earlier than G127ATT. Genome distance metrics average nucleotide identity (ANI) (76–78 %) and digital DNA–DNA hybridization (dDDH) (20.2–21.5 %) of the isolate against available genomes of several type strains of species of the genus
Agromyces
indicated that G127ATT represented a previously undescribed species of the genus
Agromyces
. Morphological, physiological and biochemical characteristics, including lipid profile, cellular fatty acids and peptidoglycan type were in accordance with usual attributes of members of the genus
Agromyces
. The novel isolate could be differentiated from the most closely related species by extracellular expression of acid and alkaline phosphatases, trypsin and α-chymotrypsin, and utilization of l-arabinose and salicin as sole carbon sources. On the basis of the combined genomic and phenotypic features, isolate G127ATT (=DSM 111850T=LMG 32099T) is considered to represent a novel species of the genus
Agromyces
, for which we propose the name Agromyces archimandritae sp. nov.

Abstract
Prostate cancer (PCa) is the second most common malignant cancer and is a major cause of morbidity and mortality among men worldwide. There is still an urgent need for biomarkers applicable for diagnosis, prognosis, therapy prediction, or therapy monitoring in PCa. Liquid biopsies, including cell-free DNA (cfDNA) and circulating tumor cells (CTCs), are a valuable source for studying such biomarkers and are minimally invasive. In our study, we investigated the cfDNA of 34 progressive PCa patients, via targeted sequencing, for sequence variants and for the occurrence of CTCs, with a focus on androgen receptor splice variant 7 (AR-V7)-positive CTCs. The cfDNA content was associated with overall survival (OS; p = 0.014), disease-specific survival (DSS; p = 0.004), and time to treatment change (TTC; p = 0.001). Moreover, when considering all sequence variants grouped by their functional impact and allele frequency, a significant association with TTC (p = 0.017) was observed. When investigating only pathogenic or likely pathogenic gene variants, variants of the BRCA1 gene (p = 0.029) and the AR ligand-binding domain (p = 0.050) were associated with a shorter TTC. Likewise, the presence of CTCs was associated with a shorter TTC (p = 0.031). The presence of AR-V7-positive CTCs was associated with TTC (p < 0.001) in Kaplan–Meier analysis. Interestingly, all patients with AR-V7-positive CTCs also carried TP53 point mutations. Altogether, analysis of cfDNA and CTCs can provide complementary information that may support temporal and targeted treatment decisions and may elucidate the optimal choice within the variety of therapy options for advanced PCa patients.

Abstract
BACKGROUND Recurrent vasovagal syncope is common, responds poorly to treatment, and causes physical trauma and poor quality of life. Midodrine prevents hypotension and syncope during tilt tests in patients with vasovagal syncope. OBJECTIVE To determine whether midodrine can prevent vasovagal syncope in usual clinical conditions. DESIGN Randomized, double-blind, placebo-controlled clinical trial. (ClinicalTrials.gov: NCT01456481). SETTING 25 university hospitals in Canada, the United States, Mexico, and the United Kingdom. PATIENTS Patients with recurrent vasovagal syncope and no serious comorbid conditions. INTERVENTION Patients were randomly assigned 1:1 to placebo or midodrine and followed for 12 months. MEASUREMENTS The primary outcome measure was the proportion of patients with at least 1 syncope episode during follow-up. RESULTS The study included 133 patients who had had a median of 6 syncope episodes in the prior year (median age, 32 years; 73% female). Compared with patients receiving placebo, fewer patients receiving midodrine had at least 1 syncope episode (28 of 66 [42%] vs. 41 of 67 [61%]). The relative risk was 0.69 (95% CI, 0.49 to 0.97; P = 0.035). The absolute risk reduction was 19 percentage points (CI, 2 to 36 percentage points), and the number needed to treat to prevent 1 patient from having syncope was 5.3 (CI, 2.8 to 47.6). The time to first syncope was longer with midodrine (hazard ratio, 0.59 [CI, 0.37 to 0.96]; P = 0.035; log-rank P = 0.031). Adverse effects were similar in both groups. LIMITATION Small study size, young and healthy patients, relatively short observation period, and high proportion of patients from 1 center. CONCLUSION Midodrine can reduce the recurrence of syncope in healthy, younger patients with a high syncope burden. PRIMARY FUNDING SOURCE The Canadian Institutes of Health Research.

Abstract
Ehlers-Danlos Syndrome (EDS) are a heterogeneous group of genetic connective tissue disorders, and typically manifests as weak joints that subluxate/dislocate, stretchy and/or fragile skin, organ/systems dysfunction, and significant widespread pain. Historically, this syndrome has been poorly understood and often overlooked. As a result, people living with EDS had difficulty obtaining an accurate diagnosis and appropriate treatment, leading to untold personal suffering as well as ineffective health care utilization. The GoodHope EDS clinic addresses systemic gaps in the diagnosis and treatment of EDS. This paper describes a leap forward—from lack of awareness, diagnosis, and treatment—to expert care that is tailored to meet the specific needs of patients with EDS. The GoodHope EDS clinic consists of experts from various medical specialties who work together to provide comprehensive care that addresses the multi-systemic nature of the syndrome. In addition, EDS-specific self-management programs have been developed that draw on exercise science, rehabilitation, and health psychology to improve physical and psychosocial wellbeing and overall quality of life. Embedded into the program are research initiatives to shed light on the clinical presentation, underlying mechanisms of pathophysiology, and syndrome management. We also lead regular educational activities for community health care providers to increase awareness and competence in the interprofessional management of EDS beyond our doors and throughout the province and country.

Abstract
A novel bacterium designated G55GPT and pertaining to the family Acetobacteraceae was isolated from the gut of the Madagascar hissing cockroach Gromphadorhina portentosa. The Gram-negative cells were rod-shaped and non-motile. The complete 16S rRNA sequence of the strain G55GPT showed the highest pairwise similarity to Gluconacetobacter johannae CFN-Cf-55T (95.35 %), suggesting it represents a potential new genus of the family Acetobacteraceae. Phylogenetic analysis based on 16S rRNA gene and 106 orthologous housekeeping protein sequences revealed that G55GPT forms a monophyletic clade with the genus Commensalibacter, which thus far has also been isolated exclusively from insects. The G55GPT genome size was 2.70 Mbp, and the G+C content was 45.4 mol%, which is lower than most acetic acid bacteria (51-68 mol%) but comparable to Swingsia samuiensis AH83T (45.1 mol%) and higher than Commensalibacter intestini A911T (36.8 mol%). Overall genome relatedness indices based on gene and protein sequences strongly supported the assignment of G55GPT to a new genus within the family Acetobacteraceae. The percentage of conserved proteins, which is a useful metric for genus differentiation, was below 54 % when comparing G55GPT to type strains of acetic acid bacteria, thus strongly supporting our hypothesis that G55GPT is a member of a yet-undescribed genus. The fatty acid composition of G55GPT differed from that of closely related acetic acid bacteria, particularly given the presence of C19 : 1 ω9c/ω11c and the absence of C14 : 0 and C14 : 0 2-OH fatty acids. Strain G55GPT also differed in terms of metabolic features such as its ability to produce acid from d-mannitol, and its inability to produce acetic acid from ethanol or to oxidize glycerol to dihydroxyacetone. Based on the results of combined genomic, phenotypic and phylogenetic characterizations, isolate G55GPT (=LMG 31394T=DSM 111244T) is considered to represent a new species in a new genus, for which we propose the name Entomobacter blattae gen. nov., sp. nov.

Abstract
Background MiRNAs act as negative regulators of gene expression through target mRNA degradation or inhibition of its translation. In cancer, several miRNAs are upregulated and play crucial roles in tumorigenesis, making the inhibition of these oncomiRs an interesting therapeutic approach. This can be achieved by directly complementary single-stranded anti-miRNA oligonucleotides (antimiRs). A major bottleneck in antimiR therapy, however, is their efficient delivery. The nanoparticle formation with polyethylenimine (PEI) may be particularly promising, based on the PEI’s ability to electrostatically interact with oligonucleotides. This leads to their protection and supports delivery. In the present study, we explore for the first time PEI for antimiR formulation and delivery. We use the branched low molecular weight PEI F25-LMW for the complexation of different antimiRs, and analyse tumor- and metastasis-inhibitory effects of PEI/antimiR complexes in different tumor models. Results In prostate carcinoma, transfection of antimiRs against miR-375 and miR-141 leads to tumor cell inhibition in 2D- and 3D-models. More importantly, an in vivo tumor therapy study in prostate carcinoma xenografts reveals anti-tumor effects of the PEI/antimiR complexes. In advanced melanoma and metastasis, we identify by a microRNA screen miR-150 as a particularly relevant oncomiR candidate, and validate this result in vitro and in vivo. Again, the systemic application of PEI/antimiR complexes inhibiting this miRNA, or the previously described antimiR-638, leads to profound tumor growth inhibition. These effects are associated with the upregulation of direct miRNA target genes. In a melanoma metastasis mouse model, anti-metastatic effects of PEI/antimiR treatment are observed as well. Conclusions We thus describe PEI-based complexes as efficient platform for antimiR therapy, as determined in two different tumor entities using in vivo models of tumor growth or metastasis. Our study also highlights the therapeutic relevance of miR-375, miR-141, miR-150 and miR-638 as target miRNAs for antimiR-mediated inhibition.![]()

Abstract
Abstract
Background
The COMPLETE trial showed that routine and complete Percutaneous Coronary Intervention (PCI) of non-infarct related artery (non-IRA) lesions in STEMI was associated with a significant reduction in the rates of death or new myocardial infarction. However, whether this benefit is related to improved myocardial salvage and left ventricular (LV) function is unknown.
Methods
We prospectively included 465 patients with first STEMI reperfused by primary PCI. Late gadolinium-enhanced Cardiac Magnetic Resonance (CMR) was obtained during admission to measure the area at risk (AAR), IRA-infarct size (IS) as % LV mass, and myocardial salvage index (MSI) as % of AAR. The study was repeated in 392 of them at 6 months follow-up to compute LV volumes and ejection fraction (EF).
Results
Patients with three-vessel disease had larger IS than those with two or single vessel disease (25.4±14.5% vs 19.0±13.1% vs 19.0±12.8% LV mass respectively, p<0.05), despite no differences in AAR (33±11% LV mass for all). Accordingly, MSI decreased progressively for one, two or three-vessel disease (42.4±31.4 vs 41.5±30.6 vs 25.1±31.3% AAR respectively, p<0.01). The number of myocardial segments with microvascular obstruction (MVO) was also higher for three-vessel disease (1.9±1.9) than for two (1.1±1.7) or single-vessel disease (1.2±1.8), p<0.05. Mean follow-up EF also decreased progressively with the number of vessels involved (50.7±9.4, 49.1±11.4 and, 44.4±11.2% respectively, p<0.01). A total of 183 patients had multivessel disease. Among them, those with complete revascularization (n=51) had larger MSI (46.4±35.2 vs 34.5±29.3% AAR, p<0.04) and were less likely to have MVO phenomenon (28.6 vs 49.2%, p<0.05). However, no significant differences in the change in EF was observed between both groups (ΔEF:+4.4±6.2 vs +4.3±6.2%, p=0.985 for the interaction).
Conclusion
The presence and extent of multivessel disease influence myocardial salvage and MVO following primary PCI in STEMI. Improvement in myocardial salvage in the IRA territory and a reduction in microvascular obstruction may mediate the beneficial effects of complete revascularization.

Abstract
Abstract Cockroaches have existed for 300 million years and more than 4600 extant species have been described. Throughout their evolution, cockroaches have been associated with bacteria, and today Blattabacterium species flourish within specialized bacteriocytes, recycling nitrogen from host waste products. Cockroaches can disseminate potentially pathogenic bacteria via feces and other deposits, particularly members of the family Enterobacteriaceae, but also Staphylococcus and Mycobacterium species, and thus, they should be cleared from sites where hygiene is essential, such as hospitals and kitchens. On the other hand, cockroaches also carry bacteria that may produce metabolites or proteins with potential industrial applications. For example, an antibiotic-producing Streptomyces strain was isolated from the gut of the American cockroach Periplaneta americana. Other cockroach-associated bacteria, including but not limited to Bacillus, Enterococcus, and Pseudomonas species, can also produce bioactive metabolites that may be suitable for development as pharmaceuticals or plant protection products. Enzymes that degrade industrially relevant substrates, or that convert biomasses into useful chemical precursors, are also expressed in cockroach-derived bacteria and could be deployed for use in the food/feed, paper, oil, or cosmetics industries. The analysis of cockroach gut microbiomes has revealed a number of lesser-studied bacteria that may form the basis of novel taxonomic groups. Bacteria associated with cockroaches can therefore be dangerous or useful, and this review explores the bacterial clades that may provide opportunities for biotechnological exploitation. Key points • Members of the Enterobacteriaceae are the most frequently cultivated bacteria from cockroaches. • Cultivation-independent studies have revealed a diverse community, led by the phyla Bacteroidetes and Firmicutes. • Although cockroaches may carry pathogenic bacteria, most strains are innocuous and may be useful for biotechnological applications.

Abstract
Abstract
Prostate cancer, is still a major cause of morbidity and mortality among men worldwide. The expression of the survival and proliferation factor progranulin (GP88) has not yet been comprehensively studied in PCa tumors. The aim of this study was to characterize GP88 protein expression in PCa by immunohistochemistry and to correlate the findings to the clinico-pathological data and prognosis. Immunohistochemical staining for GP88 was performed by TMA with samples from 442 PCa patients using an immunoreactive score (IRS). Altogether, 233 cases (52.7%) with negative GP88 staining (IRS<2) and 209 cases (47.3%) with positive GP88 staining (IRS≥2) were analyzed. A significant positive correlation was found for the GP88 IRS with the PSA value at prostatectomy and the cytoplasmic cytokeratin 20 IRS, whereas it was negatively associated with follow-up times. The association of GP88 staining with prognosis was further studied by survival analysis (Kaplan-Meier, univariate and multivariate Cox's regression analysis). Increased GP88 protein expression appeared as independent prognostic factor for overall, disease-specific and relapse-free survival in all PCa patients. Interestingly, in the subgroup of younger PCa patients (≤65 years), GP88 positivity was associated with a 3.8-fold (P=0.004), a 6.0-fold (P=0.008) and a 3.7-fold (P=0.003) increased risk for death, disease-specific death and occurrence of a relapse, respectively. This finding gains impact against the background of increasing numbers of PCa cases among younger men below 65 years of age. Summarizing, GP88 protein positivity appears to be an independent prognostic factor for PCa patients.

Abstract
Background:The introduction of biologics has transformed care for children with systemic juvenile idiopathic arthritis (SJIA). Differences in treatment approaches between countries and how they have changed over time are not well studied.Objectives:We contrast the initial features, treatment and 12-month outcome in SJIA across 10 JIA registers in Europe and North America.Methods:Data were extracted locally from 10 Registers including manifestations at diagnosis, medication use over first year and outcomes (Physician Global Assessment (PGA), active joint count (AJC)) at 12 months. Data was compared before/after 2012 to assess change over time. Weighted (w) means were used to adjust for varying number of patients/Register.Results:1,149 patients; 553 had medication data for 2012-2018; primarily female and Caucasian; median age at diagnosis 5.3-8 years. Median duration of symptoms prior to first visit varied (0-3.3 months). Glucocorticoid (GC) use was common in the first year (w_average 72% (range 33-96%)). Biologic use included IL-1, IL-6 and TNF inhibitors. The proportion of patients treated with biologics, primarily anakinra, increased after 2012 (Table 1). W_mean PGA and AJC at the 12±3 month visit were 1.55 and 1.57, respectively (Table 2). At one year, the proportion of patients prescribed GC varied (w_mean 40%, range 26-60%).Conclusion:Analysis of SJIA patients across 10 countries show that time to first rheumatology visit was highly variable. Although local factors influence treatment decisions, biologic use increased after 2011; anakinra most common. Nearly 75% of patients were prescribed steroids within the first year but seemed to decrease after 1 year. More study is needed on long-term outcomes in SJIA patients within this modern era.1: Medication Usage within First Year (pre/post 2012 where available)Glucocorticoids (IV+PO)%Methotrexate%Biologic%Anti-IL-1%Anakinra%Tocilizumab%USA2010-2011n=922563333330USA2012-2018n=91501771705717Canada2005-2010n=8876601710100UK2001-2011n=69787110330UK2012-2018n=31485829191919Portugal2008-2011n=7342364330Portugal2012-2018n=19744732161621Sweden2009-2015n=50964662302830Denmark1997-2011n=83864013662Denmark2012-2018n=325012.575636319Turkey2000-2011n=71937758423720Turkey2012-2018n=11498524032289Germany2000-2011n=27173621376<1Germany2012-2018n=249574727191020Norway1997-2011n=26816212448Norway2012-2018n=510060100202080Finland2006-2011n=12424217008Finland2012-2018n=1225880082: Clinical Outcomes at 12 Months -all yearsAJCMedian [IQR]PGAMedian [IQR]GC Use, %USA0 [0, 0]0 [0,0]47Canada0 [0, 2]0.1 [0, 2.7]41UK0 [0, 0]0.5 [0, 1.7]53Portugal0 [0, 0]0.3 [0, 1]53Sweden0 [0, 0.5]0 [0, 0.5]31Denmark0 [0, 0]-26Turkey4 [2, 7]4 [3, 7]60Germany0 [0, 1]0 [0,2]36Norway0 [0, 0]0.5 [0, 2]45Finland0 [0, 0]0 [0, 0]33Disclosure of Interests:Mary Beth Son: None declared, Yukiko Kimura Consultant of: Genetech, Kristiina Aalto: None declared, Lillemor Berntson: None declared, Johnathan Dallas: None declared, Ciaran Duffy: None declared, Mia Glerup: None declared, Jaime Guzman: None declared, Troels Herlin: None declared, Petteri Hovi: None declared, Kimme Hyrich Grant/research support from: Pfizer, UCB, BMS, Speakers bureau: Abbvie, Jens Klotsche: None declared, Bo Magnusson: None declared, Vanessa McItyre: None declared, Ellen Nordal: None declared, Seza Özen: None declared, Maria Jose Santos Speakers bureau: Novartis and Pfizer, Betül Sözeri: None declared, Timothy Beukelman Consultant of: UCB, Novartis

Abstract
Postural orthostatic tachycardia syndrome (POTS) is accompanied by reduced brain blood flow, autonomic dysfunction, and orthostatic intolerance. We hypothesized that wearing a neck compression collar would attenuate orthostatic symptoms, increase brain blood flow, and influence autonomic reflexes. Ten participants with POTS (9 women, age: 36 ± 10) underwent two trials of supine rest, paced deep breathing (6 breaths/min), Valsalva maneuver (40 mmHg for 15 s), and 70° upright tilt. For one trial, participants wore a neck compression device (Q30 Innovations). Blood pressure, heart rate (HR), brain blood flow velocity, stroke volume, respiratory rate, and end-tidal gases were continuously measured. The Vanderbilt Orthostatic Symptom Score was compiled at the end of tilt. The use of the collar reduced the orthostatic symptom score of participants with POTS during upright tilt (26.9 ± 12.5 to 18.7 ± 13.1, P = 0.04). Collar compression in the supine condition reduced the low-frequency domain of HR variability (60 ± 18 to 51 ± 23 normalized units, P = 0.04) and increased the change in HR (15 ± 5 to 17 ± 6 bpm, P = 0.02) and E:I ratio (1.2 ± 0.1 to 1.3 ± 0.1, P = 0.01) during paced deep breathing. Throughout tilt, wearing the collar reduced respiratory rate (baseline: 13 ± 3 to 12 ± 4 breath/min; tilt: 18 ± 5 to 15 ± 5 breath/min; main effect of collar P = 0.048), end-tidal oxygen (baseline: 115 ± 5 to 112 ± 5 mmHg; tilt: 122 ± 10 to 118 ± 11 mmHg; main effect of collar P = 0.026). In participants with POTS, wearing the Q-collar reduced orthostatic symptoms, increased the HR response to deep breathing, and decreased resting ventilation.NEW & NOTEWORTHY We found that using a neck compression collar alleviated orthostatic symptoms in upright posture in participants with postural orthostatic tachycardia syndrome (POTS). This could be due to compression of the baroreceptors and subsequent changes in autonomic function. Indeed, we observed increased heart rate responsiveness to paced deep breathing and reductions of respiratory rate and end-tidal O2 (suggesting reduced ventilation). Further, wearing the collar reduced mean blood velocity in the brain during Valsalva perhaps due to higher brain blood volume.

Abstract
The new 2017 diagnostic criteria for hypermobile Ehlers-Danlos Syndrome (hEDS) provide a framework for diagnosing hEDS but are more stringent than the previous Villefranche criteria. Our clinical experience at the GoodHope EDS clinic was that the 2017 criteria left many highly symptomatic patients without a diagnosis of hEDS. We conducted a retrospective cohort study to confirm our clinic experience and assess the accuracy of the 2017 diagnostic criteria for hEDS in patients who had a previous hEDS diagnosis based on the Villefranche criteria. Our study found that 15% (n = 20 of 131) of patients with a prior diagnosis of hEDS met the 2017 diagnostic criteria, and many of the traits used to distinguish hEDS were not significantly more frequent in patients who met 2017 criteria versus those who did not. In both groups objective systemic manifestations were found less frequently than subjective systemic manifestations. Beighton score (BS) as assessed by primary care practitioner was found to be higher than assessment by EDS practitioner in 81% (n = 74 of 91) of cases. Generalized joint hypermobility was confirmed in only 46% (n = 51 of 111) of patients who had a previous diagnosis of hEDS. Higher BS did not correlate with increased number of systemic manifestations in our cohort. Common comorbidities of hEDS were found with similar frequency in those who met 2017 criteria and those who did not. Based on our cohort, the 2017 hEDS diagnostic criteria require refinement to improve its diagnostic accuracy.

Abstract
Eight quinoline-based hydroxyimidazolium hybrids 7a-h were prepared and evaluated in vitro against a panel of clinically important fungal and bacterial pathogens, including mycobacteria. Hybrid compounds 7c-d showed remarkable antifungal activity against Cryptococcus neoformans with a minimum inhibitory concentration (MIC) value of 15.6 µg/mL. Against other opportunistic fungi such as Candida spp. and Aspergillus spp., these hybrids showed MIC values of 62.5 µg/mL. Regarding their antibacterial activity, all the synthetic hybrids demonstrated little inhibition of Gram-negative bacteria (MIC ≥50 µg/mL), however, hybrid 7b displayed >50% inhibition against Klebsiella pneumoniae at 20 µg/mL and full inhibition at 50 µg/mL. Moreover, this hybrid was shown to be a potent anti-staphylococcal molecule, with a MIC value of 2 µg/mL (5 µM). In addition, hybrid 7h also demonstrated inhibition of Staphylococcus aureus at 20 µg/mL (47 µM). Hybrids 7a and 7b were the most potent against Mycobacterium tuberculosis H37Rv with MIC values of 20 and 10 µg/mL (46 and 24 µM), respectively. The 7b hybrid demonstrated high selectivity in killing S. aureus and M. tuberculosis H37Rv in comparison with mammalian cells (SI >20), and thus it can be considered a hit molecule for mechanism of action studies and the exploration of related chemical space.

Abstract
New sulfonamides 5/6 derived from 4-methoxyacetophenone 1 were synthesized by N-sulfonation reaction of ammonia (3) and aminopyrimidinone (4) with its sulfonyl chloride derivative 2. Sulfonamides 5 and 6 were used as precursors of two new series of chalcones 8a-f and 9a-f, which were obtained through Claisen-Schmidt condensation with aromatic aldehydes 7a-f. Compounds 5/6, 8a-d, 8f, 9a-d, and 9f were screened by the US National Cancer Institute (NCI) at 10 μM against sixty different human cancer cell lines (one-dose trial). Chalcones 8b and 9b satisfied the pre-determined threshold inhibition criteria and were selected for screening at five different concentrations (100, 10, 1.0, 0.1, and 0.01 μM). Compound 8b exhibited remarkable GI50 values ranging from 0.57 to 12.4 μM, with cytotoxic effects being observed in almost all cases, especially against the cell lines K-562 of Leukemia and LOX IMVI of Melanoma with GI50 = 0.57 and 1.28 μM, respectively. Moreover, all compounds were screened against Mycobacterium tuberculosis H37Rv, chalcones 8a-c and 9a-c were the most active showing MIC values between 14 and 42 μM, and interestingly they were devoid of antibacterial activity against Mycobacterium smegmatis and Staphylococcus aureus. These antituberculosis hits showed however low selectivity, being equally inhibitory to M. tuberculosis and mammalian T3T cells. The chalcone-sulfonamide hybrids 8a-f and 9a-f resulted to be appealing cytotoxic agents with significant antituberculosis activity.

Abstract
BACKGROUND Evidence-based resource allocation in the public health care sector requires reliable economic evaluations that are different from those needed in the commercial sector. AIMS To describe a framework for conducting economic evaluations of occupational health and safety (OHS) programmes in health care developed with sector stakeholders. To define key resources and outcomes to be considered in economic evaluations of OHS programmes and to integrate these into a comprehensive framework. METHODS Participatory action research supported by mixed qualitative and quantitative methods, including a multi-stakeholder working group, 25 key informant interviews, a 41-member Delphi panel and structured nominal group discussions. RESULTS We found three resources had top priority: OHS staff time, training the workers and programme planning, promotion and evaluation. Similarly, five outcomes had top priority: number of injuries, safety climate, job satisfaction, quality of care and work days lost. The resulting framework was built around seven principles of good practice that stakeholders can use to assist them in conducting economic evaluations of OHS programmes. CONCLUSIONS Use of a framework resulting from this participatory action research approach may increase the quality of economic evaluations of OHS programmes and facilitate programme comparisons for evidence-based resource allocation decisions. The principles may be applicable to other service sectors funded from general taxes and more broadly to economic evaluations of OHS programmes in general.
